DETAILED DESCRIPTION

[0027] To make the purpose, technical scheme and advantages of the embodiments of the present application clearer, the technical scheme in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all of the embodiments. The components of the embodiments of the present application generally described and shown in the drawings here can be arranged and designed in various different configurations. Therefore, the following detailed description of the embodiments of the present application provided in the drawings is not intended to limit the scope of the application claimed for protection, but merely represents the selected embodiments of the present application. Based on the embodiments of the present application, all other embodiments obtained by those skilled in the art without making creative work belong to the scope of protection of the present application.

[0028] Since the electronic rearview mirror is exposed to the outside for a long time, it is easily damaged by flying sand and rocks, insects, etc. The present application simulates the protection mechanism of the eye according to the principle of biomimetic biology. When the rotating disk 82 is driven forward, the iris blade 85 blocks the camera 3, simulating the closing of the eyelids, preventing debris from hitting or dust from accumulating on the camera 3, thereby protecting the camera 3. When the rotating disk 82 is driven reversely, the iris blade 85 moves away from the position of the camera 3, and the iris blade 85 no longer blocks the camera 3, simulating the opening of the eyelids, and will not affect the normal acquisition of external images and video information by the camera 3.

[0029] An electronic rearview mirror according to an embodiment of the present application comprises: a first shell 1, a camera 3 and an iris assembly 8, wherein the first shell 1 is provided with an installation cavity 12, the camera 3 is located in the installation cavity 12, the first shell 1 is provided with a collection hole 13, the collection hole 13 is cylindrical or prism-shaped and communicates with the installation cavity 12; the iris assembly 8 comprises a rotating disk 82, an iris blade 85 and a first driver, the rotating disk 82 is located in the installation cavity 12, the rotating disk 82 is annular, the inner ring of the rotating disk 82 is directly opposite to the collection hole 13, the camera 3 is also located in the ring of the rotating disk 82, so that the camera 3 collects external image / video information, the iris blade 85 is connected to the side of the rotating disk 82, the first driver is transmission-connected to the rotating disk 82, when the rotating disk 82 rotates forwardly along its axial direction, the iris blade 85 swings into the ring to cover the collection hole 13, and when the rotating disk 82 rotates reversely along its axial direction, the iris blade 85 drives out of the ring.

[0030] like Figures 1 to 7 As shown, in combination with the above embodiments, the first housing 1 can be designed to be streamlined to reduce the running resistance. The collection hole 13 can be designed to be cylindrical, triangular, quadrangular, etc. The camera 3 can be designed to be cylindrical, triangular, quadrangular, etc. The camera 3 is installed in the installation cavity 12, and the axis of the camera 3 coincides with the axis of the collection hole 13. The minimum diameter of the collection hole 13 is slightly larger than the maximum outer diameter of the camera 3 to avoid the inside of the collection hole 13 blocking the camera 3 and affecting the collection work of the camera 3. The minimum diameter of the collection hole 13 is greater than the depth of the collection hole 13. The depth scale of the collection hole 13 cannot be designed to be too large. For example, the ratio of the minimum diameter of the collection hole 13 to its depth can be 5:1 to avoid the collection hole 13 being too deep to affect the light entering the collection hole 13. The minimum diameter of the inner ring of the rotating disk 82 needs to be slightly larger than the maximum diameter of the collection hole 13 to avoid the inner wall of the rotating disk 82 blocking the light and thus affecting the normal lighting of the camera 3. The axes of the camera 3 , the collection hole 13 and the rotating disk 82 are arranged to coincide with each other, which can save installation space and thus reduce the volume of the first housing 1 .

[0031] Furthermore, when the rotating disk 82 is coaxially installed with the collection hole 13, the disk surface of the rotating disk 82 close to the collection hole 13 is recorded as the front disk surface, and the disk surface of the rotating disk 82 away from the collection hole 13 is recorded as the rear disk surface, and the iris blades 85 can be installed on the front disk surface or the rear disk surface. When there are multiple iris blades 85, the iris blades 85 can be installed on the front disk surface or the rear disk surface at the same time, or a part of the iris blades 85 are installed on the front disk surface, and the remaining part of the iris blades 85 are installed on the rear disk surface. When the rotating disk 82 rotates, the end of the iris blade 85 is driven to move, and the end of the iris blade 85 extends into the ring along the plane where the front disk surface or the rear disk surface is located, thereby completely or partially blocking the collection hole 13, thereby protecting the camera 3 and preventing the camera 3 from being damaged.

When the first driver drives the rotating disk 82 to rotate forward, the slider 88 slides along the corresponding slide groove 87, driving the iris blades 85 to gather toward the inside of the ring. When the first driver drives the rotating disk 85 to rotate reversely, the slider 88 slides along the corresponding slide groove 87, driving the iris blades 85 to disperse from the ring.

[0033] In combination with the above embodiment, the fixing frame 89 can be set on the front disk surface or the rear disk surface of the rotating disk 82, and the iris blade 85 and the fixing frame 89 are located on the front disk surface or the rear disk surface of the rotating disk 82, that is, when the fixing frame 89 is installed on the front disk surface of the rotating disk 82, the iris blade 85 is correspondingly installed on the front disk surface, and when the fixing frame 89 is installed on the rear disk surface of the rotating disk 82, the iris blade 85 is correspondingly installed on the rear disk surface.

When the rotating disk 85 rotates, the slider 88 can slide along the corresponding slide groove 87, and the friction between the two can make the slider 88 rotate in the corresponding slide groove 87. Figure 7As shown, when the rotating disk 82 rotates counterclockwise (forward), the slider 88 rotates counterclockwise and drives the iris blade 85 to swing counterclockwise, so that the end of the iris blade 85 extends into the ring, and the iris blade 85 blocks the collection hole 13.
