According to a first aspect of the present application, a camera module 10 is provided, the camera module 10 includes a camera assembly 100, a fixing member 200, a filter 300 and a temperature control assembly 400, referring to fig. 1:

the camera assembly 100 includes a camera 110 and a camera housing 120, and the camera housing 120 surrounds the camera 110 and fixes the camera 110, or the camera 110 is disposed in the camera housing 120 and fixed. In fig. 1, the number of the cameras 110 is three, and in other embodiments, more or less cameras 110 may be designed as needed. The camera 110 may be a depth camera, which can obtain depth information of the photographic subject, i.e. three-dimensional position and size information, besides the planar image, and a subsequent computing system can obtain three-dimensional stereo data of the environment and the photographic subject, and the data can be used in the fields of tracking and three-dimensional reconstruction of the photographic subject.

The fixing member 200 includes a hollow region 210 and a frame 220 surrounding the hollow region 210, or the shape of the frame 220 defines the shape of the hollow region 210. The frame 220 includes a fixing portion 221 extending toward the hollow region 210, the fixing portion 221 is connected to the camera housing 120 to fix the camera housing 120, the frame 220 is further used for being detachably connected to an external device to be fixed by the external device, and the camera assembly 100 extends forward and into the hollow region 210. The fixing portion 221 may be integrally formed with the fixing member 200, or the fixing portion 221 and the fixing member 200 may be detachably coupled and fixed as two separate members. In some embodiments shown in fig. 1, the fixing portion 221 is located at a rear side of the frame 220, and in other embodiments, the fixing portion 221 may also be located near a middle position of the frame 220 in the front-rear direction. Camera head assembly 100 extends forward and may extend a small or large portion into hollow area 210, such as when the back side of camera housing 120 is level with the back side of bezel 220, where a large portion of camera head assembly 100 extends into hollow area 210. When the camera housing 120 protrudes from the rear side of the frame 220, it is more convenient to extract and replace the camera assembly 100; when the rear side of the camera housing 120 and the rear side of the frame 220 are at the same level, the camera module 10 is advantageously miniaturized.

The filter 300 is disposed in front of the camera assembly 100 and is used for filtering a predetermined light to prevent the predetermined light from entering the camera 110. The working principle of the light filtering piece 300 is to absorb certain wavelengths, so that a shot object can be protruded, on the other hand, for example, infrared light larger than 700nm can be filtered out by the infrared light filtering piece of a mobile phone camera, the visible light within 700nm is imaged for post-processing, the infrared light does not participate in the post-processing, and the influence on the calculation result is reduced. In some embodiments, the filter 300 is made of plastic or glass plate and special dye, and the filter 300 can be selected according to the desired subject to improve the imaging quality.

Wherein, the temperature control assembly 400 comprises a heating element 410, the front side of the heating element 410 is adapted to the shape of the front side of the light filtering element 300, and the front side of the heating element 410 is attached to the rear side of the light filtering element 300. Here, the front side of the heating member 410 is adapted to the rear side of the optical filter 300, for example, the front side is of a straight plate structure, so that the optical filter 300 can be uniformly heated by the heating member 410, the temperature unevenness of the optical filter 300 can be reduced, and the accuracy of the temperature obtained by the temperature sensing member 430 can be improved. The heating element 410 can increase the surface temperature of the filter 300, prevent frost or water vapor from forming on the filter 300, and the filter 300 with a higher surface temperature can reduce the retention time of insects such as mosquitoes, flies, ants and the like on the filter 300, reduce the traces left by the insects such as mosquitoes, flies, ants and the like on the filter 300, and improve the quality of the image shot by the camera module 10.

Wherein a heat insulating member 420 is disposed between the heating member 410 and the fixing member 200 for reducing heat transfer between the heating member 410 and the fixing member 200. Since the heating member 410 can raise the surface temperature of the filter member 300, the temperature distribution of the camera assembly 100 as a whole is not uniform, for example, the temperature of the heating member 410 and the filter member 300 is higher, and the temperature of the fixing member 200 is lower. The heat insulating member 420 is made of a heat insulating material (also called thermal insulating material) which can block heat flow transmission. In some embodiments, the thermal insulation 420 may be made of one or more combinations of foam, ultra-fine glass wool, high-silica wool. The heat insulation member 420 is disposed between the heating member 410 and the fixing member 200, so that the heat transfer from the heating member 410 with a higher temperature to the fixing member 200 with a lower temperature can be reduced, the heat loss of the heating member 410 can be reduced, and the heat utilization efficiency of the camera module 10 can be improved. In addition, the heat transfer from the heating element 410 with higher temperature to the fixing element 200 with lower temperature is reduced, the temperature rise of the camera 110 caused by the temperature rise of the camera shell 120 connected to the fixing element 200 can be prevented, and the normal working temperature of the camera 110 is guaranteed. The temperature resistance limit of the nitrile rubber and the hydrogenated nitrile rubber is 177 ℃, the nitrile rubber is used in air at 121 ℃ or oil at 150 ℃ for a long time, and the heat insulation piece 420 can be made of the nitrile rubber and the hydrogenated nitrile rubber, so that the heat insulation capability of the heat insulation piece 420 is improved, and the heated piece 410 is prevented from being damaged at high temperature.

In some embodiments, referring to fig. 1, the temperature control assembly 400 further includes a temperature sensing element 430, the temperature sensing element 430 is in contact with the filter 300 to obtain the temperature of the filter 300, and the temperature sensing element 430 is a contact type temperature sensing element, and after obtaining the temperature of the filter 300, the temperature sensing element is adjusted by the heating element 410 to prevent the filter 300 from being damaged by an excessively high temperature. In some application scenarios, when the temperature of the optical filter 300 is within the design range, the heating power of the heating element 410 can be increased in a short time, so as to quickly eliminate the frost or moisture. In the specific arrangement, the heating element 410 is provided with a first through hole 411, the heat insulation element 420 is provided with a second through hole 421, and the temperature sensing element 430 penetrates through the second through hole 421 and the first through hole 411 in sequence to abut against the rear side surface of the light filtering element 300. In some embodiments including the sealing frame 510, as shown in fig. 1, the temperature sensing element 430 sequentially passes through the sealing frame 510, the second through hole 421, and the first through hole 411 to abut against the rear side of the optical filter 300. The first through hole 411 and the second through hole 421 should be larger than the temperature sensing element 430, so as to prevent the temperature sensing element 430 from contacting the heating element 410 or/and the heat insulating element 420 to interfere with the temperature sensing element 430 in obtaining the temperature of the filter 300, and to influence the accuracy of obtaining the temperature of the filter 300 by the temperature sensing element 430.

In some embodiments not including the sealing assembly 500, the light filtering element 300, the heating element 410 and the heat insulating element 420 are sequentially attached and sealed from front to back and are disposed in the hollow region 210 of the fixing member 200, and the heat insulating element 420 is detachably connected to the fixing portion 221. In these embodiments, the frame 220 of the fixing member 200 surrounds the optical filtering member 300, the heating member 410 and the heat insulating member 420, so that the optical filtering member 300, the heating member 410 and the heat insulating member 420 do not protrude from the frame 220, and the frame 220 plays a role in protecting these components and preventing collision and damage. Moreover, the optical filter 300, the heating element 410 and the thermal insulation element 420 are disposed in the hollow region 210 of the fixing member 200, which is beneficial to the subsequent overall sealing of the camera assembly 100.

In some embodiments, referring to fig. 1, camera assembly 100 further includes a connector 130 coupled to camera housing 120 and extending away from camera housing 120.

In the embodiments shown in fig. 1, the connecting member 130 is detachably connected to the fixing portion 221 of the frame 220 and is fixed by the fixing portion 221. In other embodiments, the connecting member 130 is detachably connected to and fixed to the other portion of the bezel 220 except for the fixing portion 221. In the embodiments shown in fig. 1, the connecting member 130 and the fixing portion 221 are detachably connected and fixed by screws, and in other embodiments, a snap-fit manner may also be used. When the camera assembly 100 fails or needs to be upgraded, the camera assembly 100 can be conveniently detached from the camera module 10 and replaced with a new one. Additionally, camera head 110 may also be removed from camera head assembly 100 and replaced with a new one.

In some embodiments, camera assembly 100 further includes a support member 140 coupled to camera housing 120 and extending in a direction away from camera housing 120 in the up-down direction. When the camera head assembly 100 extends forward and protrudes into the hollow region 210, the supporting member 140 interferes with the fixing portion 221. Referring to fig. 1, the supporting member 140 is disposed below the camera housing 120, and in other embodiments, may be disposed above the camera housing 120 according to actual design requirements. The connection position of the support member 140 and the camera housing 120 may be selected according to the design distance of the camera 110 and the filter 300. For example, when the design distance between the camera 110 and the filter 300 is small, the support 140 is connected to the camera housing 120 near the front side; when the design distance between the camera 110 and the filter 300 is large, the support member 140 is attached to the camera housing 120 near the rear side. Thus, by selection of the location of the connection of the support member 140 to the camera housing 120, a small or large portion of the camera head assembly 100 may be extended into the hollow region 210. The front side of the supporting member 140 close to the camera housing 120 is connected, so that the protruding degree of the camera assembly 100 relative to the rear side of the fixing member 200 can be reduced, the length of the camera module 10 in the front-rear direction can be reduced, and the camera module 10 can be miniaturized.
