Detailed Description

In order to make the purpose, features and advantages of the present application more obvious and understandable, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is obvious that the embodiments described below are only a part of the embodiments of the present application, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.

The invention is further elucidated with reference to the drawings and the embodiments.

In the description of the present application, it is to be understood that the terms "upper", "lower", "top", "bottom", "inner", "outer", and the like, indicate orientations or positional relationships based on the orientations or positional relationships shown in the drawings, are only for convenience in describing the present application and simplifying the description, and do not indicate or imply that the referenced devices or elements must have a particular orientation, be constructed and operated in a particular orientation, and thus, are not to be construed as limiting the present application.

As shown in the figures, the camera module of the unmanned vehicle comprises a module housing 100 and a camera module 200. A chamber is provided in the module case 100 for installing the camera module 200.

As a specific example, the module housing 100 includes a front housing 110 and a rear housing 120, and a panel of the front housing 110 is mounted in a front windshield of the unmanned vehicle, and may be specifically pasted with 3M glue on the surface and then pasted on the front windshield of the vehicle.

The panel of the front casing 110 is provided with a hollow area 111, but the front casing 110 and the rear casing 120 are made of opaque materials, and light leakage in the whole chamber is basically absent, so that the shooting environment of the shooting mechanism 230 is ensured. The hollow area 111 of the front housing 110 comprises an upper area 111A and a lower area 111B, the upper area 111A faces the camera 230, the diameter of the upper area 111A is smaller than that of the camera 230, so as to ensure that the camera part of the camera 230 cannot extend out of the hollow area 111, and as shown in the figure, the position is the facing angle between the camera and the hollow area 111, and the distance between the hollow area 111 and the camera is the closest (i.e. the rotation track of the camera is at most tangent to the hollow area 111), so as to ensure that the camera does not interfere with the front windshield of the vehicle during the adjustment process.

The wiring harness of the camera directly enters the roof interior trim after passing through the wiring hole on the rear shell 120, and the number of the wiring harnesses leaked outside is small. If the maintenance camera needs to be replaced subsequently, the rear shell 120 can be taken down only by detaching four screws on two sides of the rear shell 120, the front shell 110 does not need to be detached, and the external arrangement of the front module and the rear module relative to the vehicle can be guaranteed to be unchanged.

As a specific example, the camera module 200 includes a connecting shaft 210, a wave plate 220 and a camera mechanism 230. The connecting shafts 210 are located on two sides of the camera mechanism 230, one side of each connecting shaft is installed in the rear housing 120, and the other side of each connecting shaft penetrates through the rear housing 120 and is connected with the wave plate 220. The wave plate 220 drives the camera 230 to rotate along a plane perpendicular to the hollow area 111. Because the inclination angles of the front windshield glass of different vehicle types are different, the angle of the camera can be adjusted by rotating the pointer, so that the functions of image acquisition, obstacle detection and the like of the unmanned vehicle are realized.

As a specific example, the wave plate 220 is provided with a rotating pointer, the direction of the rotating pointer is consistent with the imaging angle of the imaging mechanism 230, and the imaging direction of the imaging mechanism 230 can be directly adjusted by controlling the direction of the rotating pointer.

As a specific embodiment, the rear housing 120 is provided with connecting blocks 121 at two sides, one connecting block 121 is provided with a through hole 122, the connecting shaft 210 passes through the through hole 122 and then is connected with the wave plate 220, and the other connecting block 121 is provided with a round hole for the connecting shaft 210 to fixedly pass through. The arrangement of the connection block 121 can improve the connection rigidity of the entire camera module 200 and the module case 100 and the stability in the rotation process.

As a specific example, the rear bracket 240 is disposed on the back of the camera 230, the rear bracket 240 is fixedly connected to the camera 230, and both sides of the rear bracket 240 are connected to the connecting shaft 210. Groove-shaped fixing portions 241 are disposed at both sides of the rear bracket 240, and through holes 242 are disposed on a base of the groove-shaped fixing portions 241 and fixedly connected to the connecting shaft 210 by nuts. The rotation of the rotary pointer drives the rotation of the connecting shaft 210, and the connecting shaft 210 drives the rotation of the rear bracket 240, thereby adjusting the angle adjustment of the camera mechanism 230. In contrast to the solution in which the connection shaft 210 is directly connected to the imaging mechanism 230, in this solution, the end of the connection shaft 210 may be broken by stress in a long-term use. By adopting the scheme, the camera shooting mechanism 230 and other parts can be replaced conveniently, stress on the end part of the connecting shaft 210 can be reduced, and durability is improved.

As a specific example, the connecting shaft 210 connected to the circular hole employs the damping rotating shaft 211 to reduce the influence of the vibration of the entire vehicle on the image pickup mechanism 230.

Although the preferred embodiments of the present invention have been described in detail, the present invention is not limited to the details of the foregoing embodiments, and various equivalent changes (such as number, shape, position, etc.) may be made to the technical solution of the present invention within the technical spirit of the present invention, and the equivalents are protected by the present invention.
