The electronic device 100 provided in the embodiments of the present application is described in detail below with reference to the accompanying drawings through specific embodiments and application scenarios thereof.

As shown in fig. 1 to 6, an electronic apparatus 100 according to an embodiment of the present invention includes first and second brackets 10 and 20, a winding shaft 40, a display screen 30, a driving assembly, and a transmission assembly.

Specifically, the first bracket 10 is connected with the second bracket 20, and the second bracket 20 is movable in a first direction with respect to the first bracket 10. The winding shaft 40 is rotatably provided to the second bracket 20 about its own axis. Drive assembly locates first support 10, drive assembly is connected with second support 20, drive assembly is connected with drive assembly and winding shaft 40 respectively, the first end and the first support 10 of display screen 30 are connected, the second end and the winding shaft 40 of display screen 30 are connected, drive assembly drive second support 20 moves in the first direction, and drive the activity of drive assembly, drive assembly drives winding shaft 40 and rotates around its own axis, so that display screen 30 convolutes in winding shaft 40, or for the unwinding of winding shaft 40.

In other words, the electronic apparatus 100 according to the embodiment of the present invention, as shown in fig. 5, mainly includes the first bracket 10 and the second bracket 20 that are engaged with each other, the winding shaft 40 provided on the second bracket 20, the display screen 30 having flexibility, the driving component capable of providing a driving source, and the transmission component that realizes force transmission.

As shown in fig. 1 and 2, the first support 10 and the second support 20 are movably connected, and the second support 20 is movable in a first direction relative to the first support 10, for example, the second support 20 is movable toward the first support 10 or away from the first support 10.

The display screen 30 is disposed on the first stand 10 and the second stand 20, and a winding shaft 40 is provided on the second stand 20. A first end of the display 30 is connected to the first bracket 10, and a second end of the display 30 is connected to the winding shaft 40.

As shown in fig. 3 to 4, since the second end of the display screen 30 can be wound around the winding shaft 40, the position of the second end of the display screen 30 can be controlled by controlling the rotation or movement of the winding shaft 40. For example, by controlling the rotation direction of the winding shaft 40, the second end of the display screen 30 can be wound on the winding shaft 40 or released from the winding shaft 40. The second end of the display screen 30 can be synchronously translated by controlling the winding shaft 40 to translate along the first direction. Meanwhile, the winding shaft 40 is controlled to rotate and translate at the same time, so that the winding shaft 40 can rotate and translate at the same time, and the display screen 30 can be automatically unfolded and stored.

As shown in fig. 5, when the electronic apparatus 100 is horizontally disposed, the first direction may be set to be a horizontal direction, which can effectively reduce the thickness of the electronic apparatus 100 in the up-down direction. As shown in fig. 2 and 6, when the second bracket 20 moves in the first direction, the distance between the first bracket 10 and the second bracket 20 gradually increases. The second end of the display screen 30 is extended relative to the winding shaft 40 by the driving assembly cooperating with the winding shaft 40. When the second support 20 moves to the first preset position along the first direction, the state of the display 30 may be set to the limit unfolded state where the area of the display 30 is the largest.

As shown in fig. 1 and 5, when the second bracket 20 moves leftward, the distance between the first bracket 10 and the second bracket 20 gradually decreases. The second end of the display screen 30 is wound around the winding shaft 40 by the driving assembly cooperating with the winding shaft 40. When the second support 20 moves leftward to a second preset position, the state of the display 30 may be set to an initial state, in which the area of the display 30 is the smallest.

When the first direction is divided into left and right as shown in fig. 5 and 6, the display screen 30 is unfolded when the second stand 20 moves to the right; and when the second stand 20 moves leftward, the display screen 30 is received.

Further, a driving assembly is provided on the first bracket 10 and can be connected with the second bracket 20. That is, the driving assembly can drive the second carriage 20 to move in the first direction with respect to the first carriage 10. When the first bracket 10 and the second bracket 20 both extend in the horizontal direction, the driving assembly can displace the second bracket 20 in the horizontal direction with respect to the first bracket 10. It should be noted that the driving assembly can drive the second bracket 20 to move in the first direction, and drive the winding shaft 40 to move in the first direction; or the winding shaft 40 is driven to move in the first direction, so as to drive the second bracket 20 to move in the first direction, which is not limited herein.

And, the driving assembly can drive the transmission assembly to move, and the transmission assembly is connected with the winding shaft 40. Therefore, when the driving assembly drives the winding shaft 40 to move along the first direction, the transmission assembly can synchronously drive the winding shaft 40 to rotate around the axis of the transmission assembly, and meanwhile, the winding shaft 40 can also move along the first direction along with the second bracket 20.

That is, the driving assembly and the transmission assembly cooperate to drive the second bracket 20 to generate the first-direction displacement, and simultaneously, the winding shaft 40 can rotate around its own axis and synchronously move with the second bracket 20, so that the display screen 30 can be released from the winding shaft 40 or wound on the winding shaft 40, and the display screen 30 can be enlarged or reduced.

For example, when the driving assembly drives the transmission assembly to move rightward, the second bracket 20 moves rightward, and the winding shaft 40 can also move rightward. The transmission assembly drives the winding shaft 40 to rotate anticlockwise around the axis of the winding shaft, the display screen 30 is released from the winding shaft 40, and the display screen 30 extends.

When the driving assembly drives the transmission assembly to move leftward, the second bracket 20 moves leftward, and the winding shaft 40 can also move leftward. The transmission assembly drives the winding shaft 40 to rotate clockwise around the axis of the winding shaft 40, the display screen 30 is wound on the winding shaft 40, and the display screen 30 contracts.

Note that the driving unit is not limited to a driving motor and the like, and may be a mechanical structure capable of performing a driving function, an external force of the electronic apparatus 100, or the like.

Thus, according to the electronic apparatus 100 of the embodiment of the present invention, the driving component is matched with the transmission component, and the winding shaft 40 can be driven to rotate around its own axis and move along the first direction, so that the display screen 30 can be wound on the winding shaft 40 or unwound relative to the winding shaft 40. The electronic device 100 has the advantages of being simple in structure, improving user experience and the like.

According to one embodiment of the present application, the drive assembly includes a support, a first lead screw 52, a movable member 53, and a motor 54. Wherein the supporting member is provided to the first bracket 10. The first lead screw 52 is rotatably provided to the support member. The movable member 53 is connected to the first lead screw 52, when the first lead screw 52 rotates, the movable member 53 is driven by the first lead screw 52 to move along the first direction, and the transmission assembly is respectively connected to the movable member 53 and the winding shaft 40. The motor 54 is connected to the first lead screw 52 to drive the first lead screw 52.

That is, as shown in fig. 5, the driving assembly mainly includes a supporting member capable of performing an installation function, a first lead screw 52 provided on the supporting member, a movable member 53 movably connected to the first lead screw 52, and a motor 54 for providing a driving source. A support is provided on the first bracket 10, and the support can support the first lead screw 52. The motor 54 is connected to the first lead screw 52 and can drive the first lead screw 52 to rotate on the support around the axis of the first lead screw 52.

When the first lead screw 52 rotates, because the movable element 53 is installed on the first lead screw 52, the first lead screw 52 is in threaded connection with the movable element 53, and when the first lead screw 52 rotates along the axis of the first lead screw 52, the movable element 53 can be driven to move along the axis of the first lead screw 52.

That is, as shown in fig. 5, when the first lead screw 52 rotates, the movable piece 53 can be driven to move in the first direction by controlling the rotational direction of the first lead screw 52. The movable member 53 is connected to the transmission element, so that the movable member 53 can drive the transmission element to move along the first direction.

Since the transmission assembly is connected to the winding shaft 40 and the winding shaft 40 is connected to the second bracket 20, the winding shaft 40 and the second bracket 20 can move in the first direction.

And, the transmission assembly can drive the winding shaft 40 to rotate around its own axis, so that the display screen 30 can be released from the winding shaft 40 or wound on the winding shaft 40, thereby realizing the enlargement and reduction of the display screen 30. The flexible screen is simple in arrangement, and automatic telescopic design of the flexible screen is achieved.

In addition, compared with the prior art, the electronic device 100 of the present application can realize both the rotation of the winding shaft 40 and the expansion or contraction of the first stand 10 and the second stand 20 by only one motor 54, thereby realizing the automatic enlargement and reduction of the display screen 30. The size of the electronic device 100 can be effectively reduced, the electronic device is convenient to be designed to be light and thin, electric energy is saved compared with a mode of driving by two motors 54, and energy consumption of the device is reduced.

In some embodiments of the invention, the support is provided with a threaded hole running through in the first direction. The transmission assembly includes a second lead screw 61, a first gear 62 and a second gear 63. The first end of the second screw rod 61 penetrates through the threaded hole to be connected with the movable piece 53, when the second screw rod 61 moves along the first direction, the second screw rod 61 is matched with the threaded hole, and the second screw rod 61 rotates around the axis of the second screw rod 61. The first gear 62 is disposed at the second end of the second lead screw 61, and the first gear 62 and the second lead screw 61 move synchronously. The second gear 63 is provided on the winding shaft 40 and moves synchronously with the winding shaft 40, and the second gear 63 meshes with the first gear 62.

The cooperation between the first lead screw 52 and the second lead screw 61 will be described in detail with reference to the accompanying drawings.

As shown in fig. 5 and 6, the support is provided with a screw hole penetrating in the first direction. The transmission assembly mainly comprises a second screw rod 61, a first gear 62 and a second gear 63. The second screw 61 passes through the threaded hole, and the second screw 61 is in threaded connection with the inner wall surface of the threaded hole.

The left end of the second screw rod 61 is movably connected with the movable piece 53, and the second screw rod 61 is in threaded connection with the support piece. The right end of the second screw 61 is connected to the first gear 62, the second gear 63 is connected to the winding shaft 40 via the first gear 62, and the second gear 63 is engaged with the first gear 62.

For example, when the motor 54 drives the first lead screw 52 to rotate counterclockwise, the movable member 53 moves leftward along the axial direction of the first lead screw 52. The movable element 53 is movably connected with the left end of the second lead screw 61, and the movable element 53 can drive the second lead screw 61 to translate leftwards. Because the second screw rod 61 is screwed with the support piece, when the second screw rod 61 translates leftwards, the second screw rod 61 can rotate around the axis of the second screw rod 61, and finally the display screen 30 is stored. Similarly, when the motor 54 drives the first lead screw 52 to rotate clockwise, the display screen 30 can be unfolded, which is not described herein. It should be noted that, according to actual requirements, the display 30 may be unfolded when the first lead screw 52 rotates counterclockwise, and the display 30 may be stored when the first lead screw 52 rotates clockwise, which is not limited herein.

The fitting relationship between the first gear 62, the second gear 63, and the take-up shaft 40 will be described in detail with reference to the drawings.

As shown in fig. 5 and 6, the first gear 62 is connected to the right end of the second lead screw 61, and the first gear 62 and the second lead screw 61 can move synchronously. Specifically, when the second lead screw 61 moves leftward, the first gear 62 can also move leftward. When the second lead screw 61 is moved rightward, the first gear 62 can also be moved rightward. When the second lead screw 61 rotates about its axis, the first gear 62 can also rotate.

Since the first gear 62 is engaged with the second gear 63, the second gear 63 is mounted on the winding shaft 40, and the winding shaft 40 is mounted on the second bracket 20. Therefore, when the first gear 62 moves to the right, the second gear 63 and the winding shaft 40 can be pushed to move to the right, and when the first gear 62 rotates, the second gear 63 can also rotate, and finally the winding shaft 40 rotates along the self axis while moving to the right, so that the display screen 30 is unfolded on the winding shaft 40. When the first gear 62 moves to the left, on the one hand, the winding shaft 40 can be rotated along its axis while moving to the left by the meshing action between the first gear 62 and the second gear 63; in another aspect, the winding shaft 40 can be rotated along its axis while moving to the right by the restoring member between the first bracket 10 and the second bracket 20 and by the cooperation of the restoring member and the motor 54, for example, a spring is provided on the first bracket 10 and the second bracket 20, and when the motor 54 drives the second lead screw 61 to move to the left, the winding shaft 40 also moves to the left by the restoring force of the spring, and the engagement between the first gear 62 and the second gear 63 is always maintained.

According to one embodiment of the present application, the first gear 62 and the second gear 63 are both bevel gears, and the axial directions of the two bevel gears are perpendicular.

That is, by providing the first gear 62 and the second gear 63 as two bevel gears perpendicular to each other, the first gear 62 and the second gear 63 mesh to form a bevel gear. The bevel gear can transmit motion and power between two intersecting shafts, namely, the first gear 62 is driven to rotate by the second screw rod 61, and the second gear 63 is driven to rotate by the first gear 62, so that the winding shaft 40 and the second gear 63 rotate synchronously. By providing the bevel gear, the power of the motor 54 is conveniently transmitted to the winding shaft 40, which is beneficial to the winding shaft 40 to simultaneously realize rotation and shielding.

In some embodiments of the present application, the support member includes a first mounting portion 511 and a second mounting portion 512. The first mounting portion 511 is provided to the first bracket 10, and a first end of the first lead screw 52 is connected to the first mounting portion 511. The second mounting portion 512 is disposed on the first bracket 10 and spaced apart from the first mounting portion 511, a threaded hole is formed in the second mounting portion 512, and the second end of the first lead screw 52 is connected to the second mounting portion 512. The movable element 53 is provided between the first mounting portion 511 and the second mounting portion 512, and the motor 54 is provided on the first mounting portion 511 or the second mounting portion 512.

Specifically, the supporting member mainly includes a first mounting portion 511 and a second mounting portion 512, which can support the first mounting portion 511 and the second mounting portion 512, the first mounting portion 511 and the second mounting portion 512 are respectively disposed on the first bracket 10 at an interval, and the first mounting portion 511 and the second mounting portion 512 are disposed opposite to each other, so that the influence on the movement of the second bracket 20 can be avoided. As shown in fig. 5 and 6, when assembling, the left end of the first screw 52 may be connected to the first mounting portion 511, and the right end of the first screw 52 may be connected to the second mounting portion 512. The first lead screw 52 may be partially or entirely located between the first and second mounting portions 511 and 512. The left end of the second screw 61 is also connected to the first mounting portion 511, and the right end of the second screw 61 is connected to the second mounting portion 512. And the first screw rod 52 is connected with the second screw rod 61 through the movable piece 53, so that the rotation of the first screw rod 52 can be converted into the translation of the second screw rod 61. And because the second mounting part 512 is provided with the threaded hole, and the second screw rod 61 is in threaded connection with the threaded hole, the translation of the second screw rod 61 can be converted into two modes of translation and rotation.

That is, as shown in fig. 5 and 6, when the motor 54 drives the first lead screw 52 to rotate on the first mounting portion 511 and the second mounting portion 512, the movable member 53 is driven to move along the first direction. The movable member 53 drives the second lead screw 61 to perform linear motion along the first direction, and simultaneously, the second lead screw 61 rotates relative to the second mounting portion 512. The first gear 62 and the second screw 61 rotate synchronously, the first gear 62 drives the second gear 63 to rotate, and the second gear 63 drives the winding shaft 40 to rotate synchronously. The rotation direction of the first lead screw 52 is driven by the motor 54, and finally the winding shaft 40 can be rotated in a certain direction, so that the display screen 30 can be released from the winding shaft 40 or wound on the winding shaft 40, thereby realizing the enlargement and reduction of the display screen 30. The motor 54 may be a motor, avoiding manual pulling or retracting of the display screen 30, optimizing user experience.

According to an embodiment of the present application, the support further includes a guide rod 513, a first end of the guide rod 513 is connected to the first mounting portion 511, a second end of the guide rod 513 is connected to the second mounting portion 512, and the movable member 53 is movably connected to the guide rod 513.

That is, the movement of the movable piece 53 and the second lead screw 61 can be guided by providing the guide 513. For example, as shown in fig. 5 and 6, the left end of the guide 513 is connected to the first mounting portion 511, and the right end of the guide 513 is connected to the second connecting portion. On one hand, the guide rod 513 connects the first mounting portion 511 with the second connecting portion, which can play a role of fixing and supporting, so as to ensure that the distance between the first mounting portion 511 and the second connecting portion is not changed, and the second lead screw 61 can accurately and smoothly move on the second bracket 20. On the other hand, the movable member 53 can move along the guide rod 513, and the guide rod 513 can guide the movement of the movable member 53, so that the movement of the movable member 53 is more stable and the repeated movement of the movable member 53 is facilitated.

According to an embodiment of the present invention, the first and second mounting portions 511 and 512 are spaced apart in a first direction, and the axes of the guide bar 513, the first lead screw 52, and the second lead screw 61 all extend in the first direction.

That is, the first and second mounting portions 511 and 512 are provided at intervals in the horizontal direction, and the positions where the first and second mounting portions 511 and 512 are provided correspond. The axes of the guide rod 513, the first lead screw 52 and the second lead screw 61 may be arranged in parallel and all extend along the first direction. The driving assembly is simple in arrangement, the overall structure of the driving assembly is more compact, and the electronic equipment is easy to achieve light and thin.

In some embodiments of the present application, the first and second mounting portions 511 and 512 are rectangular blocks, and the guide bar 513, the first lead screw 52, and the second lead screw 61 are spaced apart from each other along a length direction of the first or second mounting portion 511 or 512.

That is, as shown in fig. 5 and 6, by providing the first and second mounting parts 511 and 512 as rectangular blocks and providing the first and second mounting parts 511 and 512 as regular shapes, the machining design is facilitated. And by arranging the guide rod 513, the first lead screw 52 and the second lead screw 61 to be arranged at intervals along the length direction of the first mounting part 511 or the second mounting part 512, the various structural brackets can be compactly arranged, and the thickness and the whole volume of the electronic device 100 can be reduced.

According to an embodiment of the present invention, there are two guide rods 513, the first lead screw 52 and the second lead screw 61 are located between the two guide rods 513, and the movable member 53 is connected to the two guide rods 513 respectively.

That is, as shown in fig. 5 and 6, the number of the guide rods 513 is set to two. The two guide rods 513 are disposed opposite to each other and are connected to the first and second mounting portions 511 and 512. The first lead screw 52 and the second lead screw 61 are located between two guide rods 513, as shown in fig. 5, one guide rod 513 is located behind the first lead screw 52, and the other guide rod 513 is located in front of the second lead screw 61. The movable member 53 is sleeved on the peripheries of the two guide rods 513 and can move on the guide rods 513 along a first direction. The two guide rods 513 can not only play a role of supporting and fixing, so that the movable member 53 can move smoothly along the first direction; the moving direction of the movable piece 53 can be limited, and the movable piece 53 is prevented from deviating in the moving process.

The movable member 53 according to an embodiment of the present application includes a connection block connected to the two guide rods 513, the first lead screw 52, and the second lead screw 61, and a stopper plate disposed above the connection block, as shown in fig. 5 and 6. As shown in fig. 4, when the movable element 53 moves rightward to a position where the display screen 30 is completely unfolded, the right end of the stop plate can abut against the second mounting portion 512, and the second screw rod 61 cannot move rightward continuously, so that the display screen 30 is prevented from being damaged by pulling. Similarly, when the movable element 53 moves leftward to a position where the display screen 30 is completely accommodated, the left end of the stop plate can be stopped by the first installation portion 511, and the second screw rod 61 cannot move leftward continuously, so that the display screen 30 is prevented from being damaged by extrusion.
