[0028] The working principle of this utility model:

[0029] Refer to the instruction manual Figures 1-6 The utility model is provided with a rearview mirror body 1, a bracket body 2, a first gear 6, a servo motor 7, a second gear 8, a mounting seat 13, a mounting bracket 14 and a camera 16. The bracket body 2 is used to install the rearview mirror body 1 in the car. At the same time, the bracket body 2 provides an installation position for the camera 16. The servo motor 7 is turned on, and the servo motor 7 drives the second gear 8 to rotate. The second gear 8 drives the first gear 6 to rotate. The first gear 6 drives the mounting seat 13 to rotate. The mounting bracket 14 rotates horizontally along with the mounting seat 13. The mounting bracket 14 drives the camera 16 to rotate horizontally. The specific rotation angle can be determined by the rotation movement of the servo motor 7. The camera 16 can be made to swing back and forth horizontally within a certain range, which can effectively improve the environmental video data acquisition range of the camera 16 and effectively improve the environmental perception effect of the camera 16.

[0030] During the rotation of the second gear 8, the support rod 9 is driven to rotate, and the bidirectional screw rod 10 rotates along with the support rod 9. The rotation of the bidirectional screw rod 10 drives the screw nut 11 to move up and down, and the screw nut 11 drives the rack 12 to move up and down. The rack 12 is engaged with the sector teeth 15. During the lifting movement of the rack 12, the sector teeth 15 can be effectively swung up and down, and the sector teeth 15 drive the mounting bracket 14 to swing up and down. The mounting bracket 14 drives the camera 16 to swing up and down, so that the camera 16 can swing up and down to collect video data, which can further improve the environmental video data collection range of the camera 16 and effectively improve the camera 16's perception of the environment;

[0031] The arc guide rail 17 is designed to guide the rack 12 to swing in the horizontal direction, so that when the sector tooth 15 rotates with the mounting base 13, the rack 12 also rotates with the mounting base 13. The arc guide rail 17 performs sliding guidance and limitation between the rack 12 and the lead screw nut 11, ensuring that the rack 12 can move up and down under the drive of the lead screw nut 11, and at the same time ensuring that the rack 12 always remains in meshing state with the sector tooth 15, thereby ensuring the horizontal and vertical swing adjustment of the camera 16.

[0032] Finally, it should be noted that the above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention.
