[0024] The camera module will generate a lot of heat when working continuously. If the heat cannot be dissipated in time, it will cause changes in the performance of the internal chip, thus affecting the camera effect. Therefore, it is urgent to solve how to quickly dissipate the heat of the camera module at this stage.
[0025] In view of the above problems, an embodiment of the present application provides a camera module that can dissipate heat from the camera module to prevent heat accumulation in the camera module, thereby ensuring normal camera effects.
[0026] The technical solution of the embodiments of the present application is described in detail below with reference to the accompanying drawings.

[0028] It should be noted that the flow channel 120 is a channel for air flow, the valve 310 is a one-way valve, the sealing ring 330 is used to fix the piezoelectric ceramic sheet 320, and the connecting harness 340 is used to connect an external alternating voltage to cause the piezoelectric ceramic sheet 320 to deform in the horizontal and vertical directions. Figure 1 As shown, the piezoelectric ceramic sheet 320 can shrink in the horizontal direction, which means that the piezoelectric ceramic sheet 320 can stretch in the vertical direction. Through the above configuration, the present application utilizes the property that the piezoelectric ceramic sheet 320 will deform when powered, and changes the fluid pressure in the accommodating cavity 111 through the deformation of the piezoelectric ceramic sheet 320, so that air flows in the flow channel 120, thereby taking away heat.
[0029] See also Figure 2 In one embodiment, the heat conducting component 300 further includes a cover 350 , and the cover 350 is disposed on the first housing 210 .
[0030] It should be noted that the cover 350 is used to seal on the piezoelectric ceramic sheet 320 .
[0031] See also Figure 2 In one embodiment, the heating component 200 includes a first PCB board 210 and a first thermally conductive pad 220, the first thermally conductive pad 210 is disposed on the first PCB board 220, and the first PCB board 210 is disposed in the first housing 110. Specifically, the heating component 200 includes a second PCB board 230 and a second thermally conductive pad 240, the second thermally conductive pad 240 is disposed on the second PCB board 230, and the second PCB board 230 is disposed in the first housing 110.
[0032] It should be understood that the first PCB board 220 and the second PCB board 230 of the camera module will generate a large amount of heat when working, and this heat will be transferred to the first thermal conductive gasket 210 and the second thermal conductive gasket 240, and the deformation of the piezoelectric ceramic sheet 320 will drive the air flow, thereby taking away the heat.
[0033] See also Figure 2 In one embodiment, the valve 310 includes an intake valve 311 and an exhaust valve 312, and the intake valve 311 is connected to the exhaust valve 312.

[0034] It should be noted that there is one inlet passage 121 and three exhaust passages 122, and both the inlet valve 311 and the exhaust valve 312 are one-way valves. It should be understood that when the piezoelectric ceramic piece 320 is connected to an alternating voltage, the piezoelectric ceramic piece 320 is radially compressed under the action of the electric field, and tensile stress is generated inside, so that the piezoelectric ceramic piece 320 is bent and deformed in the horizontal direction. Further, when the piezoelectric ceramic piece 320 is stretched in the horizontal direction under the action of the alternating voltage, the volume of the accommodating chamber 111 increases, the fluid pressure in the accommodating chamber 111 decreases, the inlet valve 311 opens, and air enters the accommodating chamber 111 from the inlet passage 121. When the piezoelectric ceramic piece 320 contracts in the horizontal direction under the action of the alternating voltage, the volume of the accommodating chamber 111 decreases, the fluid pressure in the accommodating chamber 111 increases, the exhaust valve 312 opens, the intake valve 311 closes, and the air is discharged from the exhaust duct 312, taking away the heat of the first thermal conductive gasket 210 and the second thermal conductive gasket 240.
