With reference to fig. 3 and the example shown in fig. 2, the number of the camera modules 20 corresponds to the number of the mounting holes 103, one camera module 20 is fixed on the first bottom wall 111 of the first housing 11, and the lens of the one camera module 20 is exposed out of the mounting hole 103 of the first housing 11. The other camera module 20 is fixed to the fourth bottom wall 121 of the second housing 12, and a lens of the other camera module 20 is exposed out of the mounting hole 103 of the second housing 12.

In the embodiment of the present invention, the specific structure and function of the two camera modules 20 are the same, and for brevity, the first bottom wall 111 of the first housing 11 fixed to one camera module 20 is used as an example. Referring to the example shown in fig. 4 and 5 together, fig. 4 is a schematic structural diagram of the camera module in fig. 1, and fig. 5 is a cross-sectional view taken at B-B in fig. 4. The camera module 20 may include a lens holder 21, a lens set 22, a conducting structure 23, an image sensor and a mounting holder 24. The mirror base 21 can be fixed to the first bottom wall 111 of the first housing 11 by means of a threaded fastener, and a cavity, and a first opening 21a, a second opening 21b and a third opening 21c respectively communicated with the cavity are arranged in the mirror base 21. The lens group 22 includes a first lens 221 and a second lens 222, the first lens 221 is connected to the lens holder 21 and covers the first opening 21a, and the second lens 222 is connected to the lens holder 21 and covers the second opening 21b. The mounting base 24 can also be fixed to the mirror base 21 by a threaded fastener and cover the third opening 21c, wherein the second lens 222 divides the cavity of the mirror base 21 into two parts, the first lens 221, the second lens 222 and the mirror base 21 enclose to form the first sealed cavity 211, the conducting structure 23 is disposed on the mirror base 21 to communicate the first sealed cavity 211 with the outside, the second lens 222, the mirror base 21 and the mounting base 24 enclose to form the second sealed cavity 212, the image sensor is disposed on the surface of the mounting base 24 facing the second sealed cavity 212, and the image sensor is electrically connected to the control board 30 through the FPC connector. With continuing reference to the example shown in fig. 5, the first lens 221 and the second lens 222 are coaxially disposed in sequence along the incident direction of the light. The light may enter the second sealed cavity 212 through the first lens 221 and the second lens 222 of the lens group 22, respectively, and fall on the image sensor to form an image.

Because the lens seat 21 is provided with the conducting structure 23 for communicating the first sealed cavity 211 with the outside, there is no pressure difference between the first sealed cavity 211 and the outside, when the camera module 20 is applied in a vacuum environment, neither the first lens 221 nor the second lens 222 in the lens group 22 is deformed due to the change of pressure, that is, the pressure cannot affect the structural stability of the lenses of the lens group 22, thereby ensuring the imaging quality of the camera module 20. For example, the conducting structure 23 may be a through hole, alternatively, the conducting structure 23 may also be formed by dispensing between the first lens 221 of the lens set 22 and the lens base 21, so that the first sealed cavity 211 communicates with the outside, so as to achieve the similar effects as described above. Alternatively, the conducting structure 23 may also be a component for adjusting a pressure difference between the outside and the first sealed cavity 211, so as to balance the pressures of the outside and the first sealed cavity 211.

Further, the first lens 221 is a concave-convex positive lens, and the second lens 222 is a concave-convex negative lens, wherein the light incident surface and the light emitting surface of the first lens 221 are both curved outward, i.e. curved in a direction opposite to the incident direction of the light, and the light incident surface of the second lens 222 is curved toward the inside of the first sealed cavity 211, i.e. curved in the direction opposite to the incident direction of the light. In other words, the lens of the camera module is a fisheye lens, so that the lens of a single camera module 20 can achieve the maximum photographing angle of view, and the combination of two camera modules 20 can obtain a 360 ° field angle, so as to meet the use requirement of a user for taking panoramic photos or videos.

Further, the first sealed cavity 211 and the second sealed cavity 212 are disposed at an angle, and for example, the first sealed cavity 211 may be disposed horizontally, and the second sealed cavity 212 may be disposed vertically. The camera module 20 further includes a reflective mirror 25, the reflective mirror 25 is accommodated in the second sealed cavity 212, and the reflective mirror 25 can reflect the light passing through the second lens 222 to the image sensor. With such a design, the thickness of the camera module 20 can be reduced to a certain extent, so that the camera module 20 is thinner and thinner.

For the control board 30, the control board 30 is provided with electronic components (not shown), including but not limited to a main control chip or a communication chip for generating heat when the camera is in operation. In the embodiment of the present invention, the heat generating element may be at least partially in contact with the third bottom wall 113 of the first housing 11 through the thermal pad 50, so as to conduct the heat generated by the electronic component to the housing 10. Illustratively, the thermal pad 50 is a thermal conductive silicon paste, which may have low volatility to reduce adverse effects of silicone oil being easily extracted in a vacuum environment.

Optionally, the camera further includes an aerospace electrical connector 60, the aerospace electrical connector 60 is fixed to an end of the housing 10 away from the camera module 20, and the aerospace electrical connector 60 is electrically connected to the control board 30.
