For explaining the specific structure of the camera of the present application, please refer to fig. 1, and fig. 1 is a schematic structural diagram of an embodiment of the camera of the present application. As shown in fig. 1, in the present embodiment, the camera 10 includes: the camera comprises a shell, a lens 1, an axial flow fan 2, a camera heat source 3, a heat dissipation block 4 and a blowing fan 5.

Wherein the housing comprises a first housing 8 and a second housing 9 connected to each other; the lens 1 is fixed on the first shell 8; the axial flow fan 2 is arranged on the first side, close to the second shell 9, of the lens 1, and the axial flow fan 2 comprises an axial flow fan suction opening 21 and an axial flow fan air outlet 22; a camera heat source 3 disposed on a second side of the lens 1, the second side being adjacent to the first side; the heat dissipation block 4 is arranged on one side, away from the lens 1, of the camera heat source 3; the air outlet 22 of the axial flow fan is opposite to one end of the heat dissipation block 4 close to the second shell 9; the blowing fan 5 is arranged opposite to one side of the heat dissipation block 4 away from the camera heat source 3; the blowing fan 5 comprises a blowing fan suction opening 51 and a blowing fan air outlet 52, and the blowing fan suction opening 51 is arranged opposite to the radiating block 4; the axial fan 2 blows air to the heat dissipation block 4, and the blower fan 5 discharges hot air dissipated from the heat dissipation block 4 to dissipate heat from the camera heat source 3.

Specifically, the heat sink 4 is closely attached to the camera heat source 3 to dissipate heat conducted by the camera heat source 3 to the ambient environment by radiation, so that the temperature of the air near the heat sink 4 is raised, and since the axial flow fan 2 is disposed on the first side of the lens 1 and the camera heat source 3 and the heat sink 4 are disposed on the second side of the lens 1, the heat radiated from the heat sink 4 has less influence on the air near the first side of the lens 1. Relatively cool air (hereinafter referred to as cool air for convenience of description) near the first side of the lens 1 is sucked in through the axial fan inlet 21 and blown out through the axial fan outlet 22 to accelerate the heat dissipation of the heat dissipation block 4 and balance the temperature of the air near the heat dissipation block 4, so that the heat flow temperature near the camera heat source 3 and the heat dissipation block 4 is reduced by mixing the cool air and the hot air. The blowing fan 5 is disposed on a side of the heat dissipation block 4 away from the camera heat source 3, and the blowing fan suction opening 51 is used for sucking cold air blown out from the axial fan air outlet 22 and hot air dissipated from the heat dissipation block 4, and discharging the hot air through the blowing fan air outlet 52, so as to further perform air suction and heat dissipation on the heat dissipation block 4.

The blower fan 5 has an air channel and includes a blower fan inlet 51 and a blower fan outlet 52, the direction of which is limited, and the blower fan inlet 51 can accurately suck the cold air blown out from the axial fan outlet 22 and the hot air emitted from the heat dissipation block 4, and guide the hot air to a desired position through the air channel and the blower fan outlet 52.

The axial fan 2 has no air duct, the axial fan suction opening 21 and the axial fan air outlet 22 have no direction, and can be vertically or horizontally installed according to the internal structure of the camera 10, and only the suction opening 21 needs to suck air at a position corresponding to the air suction opening.

Further, since the camera generally includes the blowing fan, and the blowing fan has a relatively large number of structures and is relatively complex to install, and the axial flow fan has a relatively small number of structures and is relatively simple to install, in consideration of technical difficulty and cost, the axial flow fan 2 is used as an additional fan in the camera 10 to form a dual duct with the blowing fan 5.

Different from the prior art, in the embodiment, the axial flow fan 2 is added to the assembly of the lens 1, and the axial flow fan 2 is used for sucking cold air, so that the cold air blown out by the axial flow fan 2 is mixed with air near the heat dissipation block 4, and then the air is sucked by the air blowing fan 5, and heat radiated by the camera heat source 3 and the heat dissipation block 4 is taken away to the maximum extent by utilizing heat convection. The heat dissipation of the camera heat source 3 and the heat dissipation block 4 can be accelerated through the synergistic effect of the double fans, so that the heat dissipation efficiency is improved, and the service life of the electronic element is prolonged.

Referring to fig. 1, in the present embodiment, the camera 10 includes a first bracket 11, and the axial flow fan 2 is disposed on a first side of the lens 1 through the first bracket 11.

Specifically, please refer to fig. 2, fig. 2 is a schematic perspective view of a first bracket according to an embodiment of the camera of the present application. As shown in fig. 2, in the present embodiment, the first bracket 11 includes a first fixing plate 111, a connecting plate 112, a second fixing plate 113, a first through hole 114, and a second through hole 115.

The connecting portion 112 is perpendicular to the first fixing plate 111 and the second fixing plate 113, and two ends of the connecting portion 112 are connected to one end of the first fixing plate 111 and one end of the second fixing plate 113, respectively; wherein, the projection of the second fixing plate 113 on the plane where the first fixing plate 111 is located does not overlap with the first fixing plate 111.

A first through hole 114 is formed in the first fixing plate 111 on a side close to the connecting portion 112, so that a bolt fastens the first bracket 11 and the movement assembly of the lens 1 through the first through hole 114. The second fixing plate 113 has a hole in the middle for accommodating the axial fan 2, and a plurality of second through holes 115 are uniformly disposed on the periphery of the hole along the circumferential direction of the hole, so that the bolt fastens the axial fan 2 and the first bracket 11 through the second through holes 115, and the axial fan 2 is disposed on the first side of the lens 1 through the first bracket 11.

In this embodiment, the axial fan 2 is fixed to the first side of the lens 1 through the first bracket 11, and the axial fan suction opening 21 and the axial fan air outlet 22 form a complete air duct, so that the fan blades can be distributed in the whole air duct, and the air is pushed by the blades to accelerate the air flow, thereby improving the heat dissipation effect.

With continued reference to fig. 3, fig. 3 is a partially exploded view of an embodiment of the camera of the present application. As shown in fig. 3, in the present embodiment, the axial fan 2 is fastened to the first bracket 11 by a bolt 12, the first bracket 11 is provided with a corresponding hole for accommodating the axial fan 2, and is provided with a second through hole 115, the axial fan 2 is correspondingly provided with a through hole 215, and further, the first bracket 11 is connected to the core assembly of the lens 1 by the bolt 12, so that the axial fan 2 is disposed on the first side of the lens 1 by the first bracket 11.

Referring to fig. 1, in the present embodiment, the camera heat source 3 further includes a chip.

The chip includes an Image Signal Processor (ISP), a Digital Signal Processor (DSP), and a Double Data Rate (DDR) SDRAM. Specifically, the ISP is used to process output data of an Optical sensor (Optical Sensors), the restored Optical image is converted into an electrical signal, the electrical signal is converted into a digital signal through analog-to-digital conversion, the digital signal is processed through the DSP, and the finally processed image is stored in the DDR and converted into an image that can be seen on a screen.

When the chip works, the camera heat source 3 generates a large amount of heat, and the heat dissipation block 4 is tightly attached to the camera heat source 3 so as to dissipate the heat of the camera heat source 3 to the surrounding environment through radiation.

Because the second side of the lens 1 is adjacent to the first side, and the axial fan air outlet 22 is disposed opposite to the camera heat source 3 and the end of the heat dissipation block 4 close to the second housing 9, the axial fan 2 can blow out the cold air sucked from the axial fan air inlet 21 through the axial fan air outlet 22, so as to accelerate the heat dissipation of the camera heat source 3 and the heat dissipation block 4.

Referring to fig. 1, in the present embodiment, the camera heat source 3 is closely attached to the heat dissipation block 4 through the heat conductive paste 32.

Wherein, the camera heat source 3 is closely attached to the heat dissipation block 4 through the heat conduction mud 32 for heat dissipation.

The heat conductive paste 32 includes silicone resin, heat conductive filler, and adhesive material.

Specifically, the heat-conducting mud is a jelly prepared by taking silicon resin as a base material, adding a heat-conducting filler and a bonding material according to a certain proportion and processing the base material by a special process. In practical application, the heat-conducting putty is also called as heat-conducting putty, heat-conducting glue mud and the like. The heat conduction mud has excellent high and low temperature resistance, excellent weather resistance, radiation resistance and excellent dielectric property, has viscosity, does not need to use an adhesive product which does not contribute to the heat conduction property to improve the application property, is suitable for filling unformed gaps, cannot deform in a static use process after being formed, and has excellent aging resistance.

In the present embodiment, the heat conductive paste 32 is kneaded into a thin layer as required, and is filled between the camera heat source 3 to be cooled and the heat dissipation block 4, so that the camera heat source 3 and the heat dissipation block 4 are in close contact. Through the way, the thermal resistance between the camera heat source 3 and the heat dissipation block 4 can be reduced, so that the camera heat source 3 can quickly conduct the generated heat to the heat dissipation block 4, the temperature of the electronic element can be effectively reduced, the service life of the electronic device can be prolonged, and the reliability of the electronic device can be improved.

Referring to fig. 1, in the present embodiment, a heat dissipating block fin 41 is disposed on a side of the heat dissipating block 4 away from the camera heat source 3. As shown in fig. 1, the axial fan outlet 22 is disposed opposite to one end of the heat radiation block fin 41 close to the second housing 9, and the blower fan suction opening 51 is disposed opposite to one side of the heat radiation block fin 41 away from the camera heat source 3.

In the present embodiment, the axial fan inlet 21 sucks air and blows it out through the axial fan outlet 22, and the blower fan inlet 51 sucks air blown out from the axial fan outlet 22 and hot air blown out from the heat dissipation block fins 41 and blows it out through the blower fan outlet 52 to dissipate heat from the camera heat source 3.

Specifically, the heat conduction mud 32 is tightly attached to the camera heat source 3 and the heat dissipation block 4 to reduce the thermal resistance between the camera heat source 3 and the heat dissipation block 4, so that the camera heat source 3 can quickly conduct the generated heat to the heat dissipation block 4, the heat is conducted through the heat dissipation block 4, and the heat dissipation area is enlarged by using the heat dissipation block fins 41 to accelerate the heat dissipation of the camera heat source 3; the heat conducted by the camera heat source 3 is radiated to the surrounding environment through the heat radiation block fins 41, so that the temperature of the air near the heat radiation block fins 41 is raised, and since the axial flow fan 2 is arranged on the first side of the lens 1 and the camera heat source 3 and the heat radiation block fins 41 are arranged on the second side of the lens 1, the influence of the heat radiated from the heat radiation block fins 41 on the air near the first side of the lens 1 is small. Cold air near the first side of the lens 1 is sucked in by the axial fan suction opening 21 and blown out through the axial fan outlet opening 22 to accelerate heat dissipation of the heat dissipation block fin 41 and balance the air temperature near the heat dissipation block fin 41, and the heat flow temperature near the camera heat source 3 and the heat dissipation block fin 41 is lowered by mixing of the cold air and the hot air. The blowing fan 5 is disposed on a side of the heat dissipating block fin 41 away from the camera heat source 3, and the blowing fan suction opening 51 is used for sucking cold air blown out from the axial flow fan outlet 22 and hot air dissipated from the heat dissipating block fin 41, so as to further perform air suction and heat dissipation on the heat dissipating block fin 41.

In the present embodiment, the number of the heat radiation block fins 41 is at least two. Specifically, the number of the heat dissipation block fins 41 may be set according to the size of the heat dissipation block 4, and the number of the heat dissipation block fins 41 is not limited in the present application.

In the present embodiment, the heat dissipation block 4 is stacked with a plurality of heat dissipation block fins 41 on the side away from the camera heat source 3, and since the heat dissipation block fins 41 are thin-plate structures and the area of the heat dissipation block fins 41 is much larger than that of the heat dissipation block 4, the heat exchange area can be effectively increased during the heat transfer process, thereby accelerating the heat dissipation of the electronic component.

Further, because the fin structure of the radiating block fin 41 has certain uniqueness, the fluid in the radiating block fin 41 tube can form violent disturbance during heat exchange, and a boundary layer can be continuously broken, so that the thermal resistance is reduced, and the heat exchange efficiency of the whole system is greatly increased.

In the present embodiment, the heat radiation block 4 and the heat radiation block fin 41 are formed by injection molding.

Different from the prior art, in the present embodiment, the axial flow fan 2 is added to the assembly of the lens 1, and the axial flow fan 2 is used to suck cold air, so that the cold air blown by the axial flow fan 2 is mixed with air near the heat dissipation block fins 41, and then the air is sucked by the blower fan 5, and heat radiated from the camera heat source 3 and the heat dissipation block fins 41 is taken away to the maximum extent by using thermal convection. The heat dissipation of the camera heat source 3 and the heat dissipation block fins 41 can be accelerated through the synergistic effect of the double fans, so that the heat dissipation efficiency is improved, and the service life of the electronic element is prolonged.

Referring to fig. 1, in the present embodiment, the camera 10 further includes a blowing fan duct 6. As shown in fig. 1, the blowing fan duct 6 includes a duct support (not shown) so that the blowing fan 5 is fixed in the blowing fan duct 6 by the duct support, and the blowing fan duct 6 is fixed to the case by the second support 61.

With continued reference to fig. 1, in this embodiment, the camera 10 further includes a window glass 7. As shown in fig. 1, the window glass 7 is disposed on the surface of the first housing 8 and opposite to the lens 1.

In this embodiment, the window glass 7 is also located on the side of the outlet of the blower fan duct 6.

The air duct 6 of the blowing fan is arranged opposite to the window glass 7 at a predetermined angle, so that hot air guided out through the air duct 6 of the blowing fan can be blown to the window glass 7 through the conducting channel to demist the window glass 7.

Specifically, when the ambient temperature of the camera is rapidly reduced, the surface temperature of the window glass used by the camera is also reduced, and the damp and hot air in the camera meets the cold window glass and then is fogged on the inner surface, so that the image abnormality of the camera is caused.

In the existing method for defogging a window glass, for example, manual wiping is used for defogging, however, traces are often left after wiping, and the effect of lens shooting is further affected. Or, through installing a sheath additional on the camera lens, the one end cover of sheath is on the camera lens, the other end top is tight on the clear glass of front frame, form sealed passageway between camera lens and the front frame glass, thereby with front frame clear glass, the space separation between camera lens and the sheath, the camera, clear glass's temperature just is unanimous with the camera lens, clear glass, the sheath three forms the temperature in the sealed passageway, steam in the air just can not form the water smoke on the clear glass inner wall in the guard shield like this, and influence the normal shooting function of camera, however, this kind adopts the mode of machinery install device additional, owing to having increased one deck clear glass, itself just influences photographic quality, and, clear glass itself also easily congeals into water smoke, influences the shooting. Or, set up the fan that is used for the defogging specially inside the camera, make the fan blow to camera lens direction through opening the instruction and dispel the heat defogging, however, additionally increase the fan and carry out the defogging, can make the camera power consumption more, be not conform to green's designing requirement, be unfavorable for reducing the power consumption of camera.

In this embodiment, through the angle of the export of design blast fan wind channel 6 and window glass 7, can make the hot-blast through conducting channel that blows out via blast fan wind channel 6 blow to window glass 7, dry the moisture around window glass 7 through thermal convection, prevent window glass 7 fogging to realize the defogging function.

In other embodiments, the angle between the outlet of the air duct 6 of the blowing fan and the window glass 7 is not required, and only the communication channel is required to be established between the outlet of the air duct 6 of the blowing fan and the window glass 7, for example, one section of air duct is added, the hot air exhausted from the air duct 6 of the blowing fan is guided to the window glass 7 through the air duct, so that the moisture around the window glass 7 is dried through heat convection, the window glass 7 is prevented from being fogged, the defogging function is realized, and the application does not limit the angle.

Through the mode, the embodiment does not need to additionally adopt a fan to demist the window glass 7, can utilize the heat generated by the camera heat source 3 to the maximum extent, and solves the problem that the window glass forms water mist under the condition of not increasing the energy consumption of the camera so as to carry out shooting smoothly in the following process.

Referring to fig. 4, fig. 4 is a schematic perspective view of a housing according to an embodiment of a camera of the present application. As shown in fig. 4, in the present embodiment, both the first case 8 and the second case 9 have a hemispherical shape.

Wherein, the shape of first casing 8 and second casing 9 all sets up to the hemisphere, is favorable to increasing heat conduction area of contact to make the inside hot-air of camera 10 can pass through the shell and radiate in the external environment, thereby further promote the radiating efficiency.

Because the axial fan 2 is disposed on the first side of the lens 1, and the camera heat source 3 and the heat dissipation block fin 41 are disposed on the second side of the lens 1, the heat radiated from the heat dissipation block fin 41 has a small influence on the air near the first side of the lens 1, that is, the air near the axial fan suction area a is still cold air, and the axial fan suction inlet 21 can suck the cold air in the axial fan suction area a and blow out the cold air to the axial fan air outlet area B through the axial fan air outlet 22. The cool air in the axial fan outlet area B is mixed with the hot air in the camera heat source heat dissipation area C to lower the temperature of the heat flow near the camera heat source 3 and the heat dissipation block fins 41. The blowing fan 5 is disposed on one side of the heat dissipation block fins 41 away from the camera heat source 3, and the blowing fan suction opening 51 is used for sucking the mixed air in the blowing fan suction area D to further perform suction heat dissipation on the camera heat source heat dissipation area C. Furthermore, the air duct 6 of the blowing fan is arranged opposite to the window glass 7 at a predetermined angle, so that the mixed air in the air-out area E of the blowing fan can be blown to the defogging area F of the window glass through the conducting channel after being led out through the air duct 6 of the blowing fan, so as to defogge the window glass 7.

In this embodiment, a clockwise heat flow circulating system is formed by the axial fan 2, the heat conducting mud 32, the heat dissipating block 4, the heat dissipating block fins 41, the blower fan 5 and the blower fan duct 6, so that the cold air sucked from the air suction area a of the axial fan can be mixed with the hot air in the heat dissipating area C of the camera heat source, the heat flow temperature near the camera heat source 3 is reduced, the mixed air in the air suction area D of the blower fan is sucked and blown out by the blower fan 5, the circulating speed of the heat flow is accelerated, and then the mixed air in the air outlet area E of the blower fan is guided to the window glass demisting area F by the blower fan duct 6, so that the mixed air window glass 7 is dried and demisted, and the heat flow temperature is further reduced. Through the mode, the heat flow temperature of the cavity near the heat source 3 of the camera can be effectively reduced, the defogging function of the window glass 7 is realized, and the service life of the electronic element is prolonged.
