Moreover, since the support base 200 is provided with the through hole 210, the spaces on the opposite sides of the support base 200 can be communicated with each other through the through hole 210, the gas circulation device 400 is arranged on one side of the support base 200, the camera 100 can transfer the heat of the camera to the plurality of radiating fins 310 of the radiating portion 300, the temperature of the radiating fins 310 is increased, so that the gas pressure in the space on the side of the support base 200 where the camera 100 is located is increased, further, the air in the space of the support 200 on the side where the camera 100 is located flows to the other side of the support 200 through the through hole 210, and at the same time, under the condition that the gas circulation device 400 works, the efficiency and the thoroughness degree of gas exchange on the two opposite sides of the supporting seat 200 can be accelerated, thereby take the heat out to outside the camera module along with gas flow, prevent the high temperature of camera 100 and camera module, guarantee that the camera module has higher life.

In this case, the area of the support base 200 capable of exchanging gas can be enlarged, and the support base 200 can be filled with the through holes 210 as much as possible, so that each position of the camera 100 corresponds to the through hole 210, the distance between each position of the camera 100 and the through hole 210 is reduced, gas carrying heat on the camera 100 flows in the space on one side of the support base 200 facing the camera 100 as little as possible, the gas flow path is reduced, and the heat dissipation efficiency of the camera module is improved. In addition, through making a plurality of through holes 210 evenly arrange, can reduce the processing degree of difficulty, promote the machining efficiency of supporting seat 200, can also reduce the adverse effect that the setting of a plurality of through holes 210 produced the overall structure intensity of supporting seat 200 as far as possible.

Specifically, the through holes 210 may be arranged in a row-by-row manner, and the through holes 210 may be disposed on the supporting base 200 in multiple rows and multiple columns. Or, the arrangement of the through holes 210 may be determined according to the shape of the support base 200, for example, in the case that the support base 200 is a circular structural member, the through holes 210 may form a plurality of circular rings with different sizes, and the circular rings are sequentially arranged on the support base 200 in a surrounding manner, so that the through holes 210 can better fill the entire support base 200.

In order to ensure that the space between the camera 100 and the supporting base 200 is relatively large while improving the heat dissipation effect, optionally, the gas circulation device 400 is disposed on one side of the supporting base 200 departing from the camera 100. Under this condition, can prevent that gas circulation device 400 from taking up the activity interval between camera 100 and the supporting seat 200, guarantee that the anti-shake effect of camera 100 and anti-shake effect can not influenced because of setting up gas circulation device 400. Moreover, under the condition of adopting the technical scheme, the camera 100 can be produced by adopting a conventional processing technology, and after the camera 100 is processed, the gas circulating device 400 is arranged on one side of the supporting seat 200 departing from the camera 100 through a connecting piece and the like, so that the adverse effect on the processing flow caused by equipment improvement can be reduced as much as possible.

Further, the surfaces of the plurality of heat dissipation fins 310 facing away from the camera head 100 may all be located on the same spherical surface, and the spherical surface protrudes toward the supporting seat 200. That is to say, one side of the heat dissipation portion 300 facing the support base 200 is a spherical structure, and the heat dissipation portion 300 protrudes toward a direction close to the support base 200, so that in the process of the camera 100 moving relative to the support base 200 to perform the pan-tilt anti-shake, the adverse effect on the anti-shake process due to the heat dissipation portion 300 can be reduced to the maximum.

Specifically, specific parameters such as the radian of the structure of each heat dissipation fin 310 away from the surface of the camera 100 may be selected correspondingly according to the moving range of the camera 100, and accordingly, the actual structural parameters of each heat dissipation fin 310 may be determined comprehensively by combining the moving intervals between the heat dissipation portion 300 and the support base 200.

Alternatively, the heat sink 310 is a flat plate-shaped structure, and the plurality of heat sinks 310 are arranged in parallel with each other. Under the condition that the heat dissipation part 300 adopts the structure, the spaces on the two opposite sides of the heat dissipation part 300 can be communicated with each other along the direction perpendicular to the thickness direction of the supporting part, so that the flowing amplitude and the flowing range of gas between any two adjacent heat dissipation fins 310 are further enlarged, the gas exchange efficiency and the thorough degree between the heat dissipation fins 310 are improved, and the heat dissipation efficiency of the camera 100 is further improved. Specifically, the thickness of the heat dissipation fins 310 may be determined according to actual conditions, and as described above, the size of the space between two adjacent heat dissipation fins 310 may be the same, or may be flexibly determined according to the thermal distribution condition of the camera head 100.
