Next, the use and operation of the adaptor device 1 according to the present embodiment will be described with reference to fig. 1 to 17 again, taking the example of disposing the infant carrier on the stroller.

When the infant carrier and the adapting device 1 need to be combined for use and collected, the adapting device 1 is opened to be in the unfolding position, at this time, the first supporting piece 100 and the second supporting piece 200 extend in opposite directions, as shown in fig. 1 and 3, the adapting device 1 can be directly placed on the ground or a table, the infant carrier is clamped on the adapting device 1, and the connection between the two is a conventional way in the art, the infant carrier can be prevented from unnecessarily shaking and the like through the adapting device 1, so that the infant can sit more comfortably. Furthermore, the adapter 1 can be fastened to the stroller, that is, the fixing base 330 is fastened to the fastening mechanism of the stroller, so that the baby basket is disposed on the stroller.

When the adapting device 1 is not needed, the baby basket, the adapting device 1 and the baby stroller can be respectively folded after being disassembled, and the adapting device 1 can also be directly folded on the baby stroller. Specifically, the pulling member 400 shown in fig. 1 and 18 is pulled upwards, which pulls the lock release operating members 360 of the two connecting mechanisms 300 simultaneously to pivot synchronously, and the lock release operating members 360 drive the locking pins 350 to slide out of the locking holes 322 of the second joints 320, as shown in fig. 17, in the process, the resetting member 370 is compressed; then, the first supporting member 100 is pushed to rotate a certain angle slightly and the pulling member 400 is released, the unlocking operation member 360 will be reset under the action of the resetting member 370, and the unlocking operation member 360 will drive the locking pin 350 to slide towards the second joint 320 again and make it be engaged with the limiting groove 323, as shown in fig. 6 and 8.

Then, the first supporting member 100 is further pushed to rotate along the direction indicated by the arrow F1 in fig. 12, and the first supporting member 100 drives the second supporting member 200 to rotate along the direction indicated by the arrow F2 in fig. 12 until the first supporting member 100 and the second supporting member 200 pivot to the folded state of the state illustrated in fig. 2, 4 and 14, in the process, the locking pin 350 slides in the limiting groove 323, as illustrated in fig. 15; the folded state of the adapter 1 can be further illustrated with reference to fig. 2 and 4.

Furthermore, during the process of pivotally folding the first support member 100 and the second support member 200, the second joint 320 drives the sliding block 380 to slide downwards along the fixing seat 330 through the connecting rod 390, so that the sliding block 380 can drive the locking mechanism of the stroller to release the lock, and the adaptor 1 can be folded on the stroller synchronously without being detached and then folded, and the folding operation is simpler.

Referring now to fig. 18-22, in a second embodiment of the present invention, the adapter 1 differs from the first embodiment only in that: the arrangement of the release operation member 360 'and the reset member 370' will be described only with respect to differences, and the description of the same parts will not be repeated.

Specifically, in the present embodiment, a pivot portion 361 'is formed at a substantially middle portion of the release operation member 360', the pivot portion 361 'is pivotally connected to the first joint 310 through a rotation shaft 3611', after the pivot portion is pivotally connected, an axial direction of the rotation shaft 3611 'is perpendicular to an axial direction of a pivot shaft of the first joint 310, an operation portion 362' is formed at a lower end of the release operation member 360 ', and the reset member 370' abuts between an upper end thereof and the first joint 310.

As shown in fig. 21, the upper end of the release operation member 360 'has a first protrusion 366 protruding toward the side thereof, the first joint 310 has a second protrusion 315 protruding from the first protrusion 366, and two ends of the reset member 370' are respectively sleeved on the first protrusion 366 and the second protrusion 315 and abut against between the release operation member 360 'and the first joint 310, so that when the operation portion 362' is pulled to move away from the first joint 310, the release operation member 360 'can pivot around the rotation shaft 3611', that is, the release operation member 360 'pivots around the rotation shaft 3611' in the direction indicated by the arrow F3 in fig. 22, and the upper end of the release operation member 360 'approaches the first joint 310 to press the reset member 370' to deform; when the operating portion 362 'is released, the reset member 370' is deformed to reset the actuating member 360 ', i.e., the actuating member 360' is pivoted in the direction indicated by the arrow F3 in fig. 22.

The folding and unfolding operation modes and principles of the adapter device 1 in this embodiment are the same as those in the above embodiments, and are not described repeatedly.

As shown in fig. 20 and 22, in the present embodiment, the first joint 310 and the second joint 320 are not limited to be locked by the locking pin, but may be locked by other methods, for example, the release operation member 360 'may be directly engaged with the second joint 320, specifically, the operation portion 362' of the release operation member 360 'is bent and protruded toward the second joint 320 to form an engaging portion 367 (see fig. 20 and 22), a locking notch 325 (see fig. 20 and 22) corresponding to the engaging portion 367 is formed at an edge of the second joint 320 adjacent to the first joint 310, when the release operation member 360' is at the initial position, the engaging portion 367 passes through an outer edge of the first joint 310 to be engaged with the locking notch 325 (see fig. 20 and 22) on the second joint 320, at this time, the first joint 310 and the second joint 320 cannot relatively rotate, when the operating portion 362 'is pulled to pivot the release operating member 360', the engaging portion 367 will be disengaged from the locking notch 325, and at this time, the first joint 310 and the second joint 320 can rotate relatively.

Referring now to fig. 23-29, in a third embodiment of the present invention, the adapter 1 differs from the first embodiment only in that: the structure of the linkage 340 and the linkage mode between the first joint 310 and the second joint 320. Only the differences will be explained below, and the description of the other similar parts will not be repeated.

In the embodiment, the linkage 340 includes a first linkage 341 and a second linkage 342, wherein a first end 3411 of the first linkage 341 is pivoted to the first joint 310 to form a first pivot point P1, a first end 3421 of the second linkage 342 is pivoted to the second joint 320 to form a second pivot point P2, and a second end 3412 of the first linkage 341 is pivoted to a second end 3422 of the second linkage 342 to form a third pivot point P3. In addition, the centers of the pivot axes of the first joint 310, the second joint 320 form a fourth pivot point P4, and the fourth pivot point P4 is located above the third pivot point P3. The first pivot point P1, the third pivot point P3, the second pivot point P2 and the fourth pivot point P4 are connected in sequence to form a four-bar linkage. When one of the first joint 310 and the second joint 320 is stressed, the first linking rod 341 and the second linking rod 342 are linked to each other, so that the four pivot points of the four-bar linkage mechanism pivot mutually, and further, the other one of the first joint 310 and the second joint 320 is pulled to pivot, thereby realizing automatic folding of the first joint 310 and the second joint 320, and enabling folding operation to be simpler and more labor-saving.

Referring to fig. 23-27, in the present embodiment, the first linking rod 341 and the second linking rod 342 are disposed between the second joint 320 and the fixing base 330. Of course, the positions of the first and second linking levers 341 and 342 are not limited thereto.

Specifically, the second joint 320 is provided with a sliding hole 326 in a penetrating manner, the sliding hole 326 is an arc-shaped structure and is concentrically arranged with the pivot axes of the first joint 310 and the second joint 320, that is, the sliding hole 326 is centered around the fourth pivot point P4. Meanwhile, a cylinder 316 is protruded from the first joint 310, the cylinder 316 slidably penetrates through the sliding hole 326, the cylinder 316 protrudes toward the fixing base 330, and is pivotally connected to the first end 3411 of the first linkage rod 341 through the cylinder 316, as shown in fig. 24.

As shown in fig. 23, the second end 3412 of the first linking rod 341 and the second end 3422 of the second linking rod 342 are pivotally connected by a shaft 381, and the shaft 381 is slidably disposed in the long hole 334 of the fixing base 330 and connected to the slider 380. Therefore, during the process of pivoting the first joint 310 and the second joint 320 together, the shaft 381 is driven to slide down along the long hole 334, and the slider 380 is driven to slide down along the sliding groove 333, as shown in fig. 28-29. Therefore, in the present embodiment, the linkage between the first joint 310 and the second joint 320 is achieved by the four-bar linkage, and the slider 380 is also synchronously driven to slide downward, thereby greatly simplifying the linkage structure between the first joint 310 and the second joint 320.

In this embodiment, the sliding hole 333 of the fixing base 330 extends vertically along the central axis L of the fixing base 330, and the long hole 334 in the sliding hole 333 also extends vertically along the central axis L, as shown in fig. 28 to 29.

The portions of the present embodiment that are not described in detail are the same as those of the first embodiment described above.

The pivotal folding of the turning device 1 in the present embodiment will be described with reference to fig. 23 to 29 again. As shown in fig. 23 and 28, when the adapter 1 is in the open state, the slider 380 is located at the topmost end of the sliding groove 333 (see fig. 23 and 28), and the positional relationship between the first linking lever 341 and the second linking lever 342 is shown in fig. 26. When the lock release operation member 360 is pulled to release the lock, the first support member 100 and the second support member 200 can be pushed to be folded in a pivoting manner, which specifically comprises the following operations:

if the first supporting member 100 is pushed to rotate in the direction indicated by the arrow F1 in fig. 23 and 28, the first joint 310 is driven by the first supporting member 100 to rotate synchronously, and the column 316 on the first joint 310 slides in the sliding hole 326 on the second joint 320 during the pivoting process of the first joint 310, as shown in fig. 27, the first end 3411 of the first connecting rod 341 is driven by the column 316 to slide along the sliding hole 326, that is, the first end 3411 of the first connecting rod 341 rotates around the fourth pivot point P4, and the position of the first end 3411 of the first connecting rod 341 will be lowered, as shown in fig. 27. During the movement of the first connecting rod 341, the position of the second end 3412 is moved downward, so as to push the shaft 381 connected to the second end 3412 to slide downward along the sliding hole 334 of the fixing holder 330, i.e., downward in the direction of the arrow F4 in fig. 26-27.

In the process of moving down the position of the first linkage 341, the second end 3422 of the second linkage 342 is pulled to move down along the sliding hole 334 (i.e., move down in the direction of arrow F4), so that the included angle between the second end 3412 of the first linkage 341 and the second end 3422 of the second linkage 342 changes, the first end 3421 of the second linkage 342 further rotates around the second pivot point P2 and pulls the second joint 320 to move down, so that the second joint 320 rotates in the direction of arrow F2 in fig. 26-27, i.e., the rotation direction of the second joint 320 is opposite to the rotation direction of the first joint 310, and in the process, the first to fourth pivot points P1-P4 of the four-bar linkage rotate mutually, as shown in fig. 27. Therefore, only one hand is needed to push the first supporting member 100 to pivot, so as to drive the second supporting member 200 to rotate reversely to close (see fig. 29), and the folding operation is simpler and more labor-saving.

Further, in the process that the first joint 310 and the second joint 320 are pivoted and closed, the slider 380 is driven to slide downwards along the sliding groove 333, when the first joint 310 and the second joint 320 are completely folded, the slider 380 slides to the bottom end of the sliding groove 333 (see fig. 29), and in the process that the slider 380 slides downwards, the lock releasing device arranged on the infant carrier can be driven to release the lock so as to realize the synchronous folding of the adapter 1 and the infant carrier.

Understandably, the relative pivotal folding of the first supporting member 100 and the second supporting member 200 can also be realized when the second supporting member 200 is stressed.

In summary, since the connection mechanism 300 of the present invention has the first joint 310, the second joint 320 and the locking pin 350 connected therebetween, the connection mechanism 300 can be conveniently unlocked by the unlocking operation members 360, 360' to achieve pivotal folding and unfolding, and the operation is simple and labor-saving, in addition, one of the first joint 310 and the second joint 320 is connected to the fixing base 330, and the fixing base 330 is used for detachably connecting to the infant carrier, so that the connection mechanism can be configured on different infant carriers according to the requirement; when the connecting mechanism 300 is applied to the adapting device 1, the adapting device 1 can be folded and unfolded conveniently and easily, the operation is more convenient, the folded adapting device 1 occupies a smaller storage space, and the adapting device 1 can be used to configure the baby carrying device on different baby carriers for use by clamping the fixing base 330 with different baby carriers, so that the use of the baby carrying device is more flexible and convenient.

The structures of the infant carrier and the infant carrier according to the present invention are conventional arrangements well known to those skilled in the art, and will not be described in detail herein.

The above disclosure is only for the purpose of illustrating the preferred embodiments of the present invention and is not to be construed as limiting the scope of the present invention, therefore, the present invention is not limited by the appended claims.
