[0022] The technical solution of this utility model will be clearly and completely described below with reference to the accompanying drawings. In addition, the forms of the various structures described in the following embodiments are merely illustrative. This utility model is not limited to the structures described in the following embodiments. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0023] Reference Figures 1-4 This utility model provides a vehicle camera mounting bracket, including a mounting frame 1. Mounting holes are provided at all four corners of the mounting frame 1. A slot 5 is provided on the inner wall of one side of the mounting frame 1 at the center position. A transparent cover 4 is adhered to the inner wall of the mounting frame 1 at the slot 5 position. A carrier frame 16 is fixed to the inner wall of the bottom of the mounting frame 1 by bolts at the center position. A connecting shaft 14 is rotatably connected to the inner wall of the top of the carrier frame 16 via a bearing. A fixing frame 7 is provided on the top of the carrier frame 16. One end of the connecting shaft 14 passes through the carrier frame 16 and is fixed to the fixing frame 7. A camera fixing and locking assembly is provided on the top of the fixing frame 7. A gear 15 is connected to the outer circumference of the connecting shaft 14 at the bottom of the carrier frame 16 via a key. A rack 13 meshing with the gear 15 is provided at the bottom of the carrier frame 16. A drive mechanism is provided on the inner wall of the bottom of the mounting frame 1. The power assembly for the reciprocating movement of the rack 13 includes a support frame 12 fixed to the inner wall of the bottom of the mounting bracket 1 by bolts. A self-locking electric push rod 11 is mounted on the top of the support frame 12. The piston end of the self-locking electric push rod 11 is fixed to the rack 13. When the self-locking electric push rod 11 is activated, the piston end of the self-locking electric push rod 11 drives the rack 13 to move left and right. When the rack 13 moves, it drives the gear 15 to rotate. The rotation of the gear 15 drives the connecting shaft 14 to rotate. The connecting shaft 14 drives the fixed bracket 7 to rotate. The fixed bracket 7 drives the camera fixed on the fixed bracket 7 to rotate, thereby realizing the adjustment of the camera angle to meet the shooting needs of different directions. At the same time, it can also observe the situation of the left and right blind spots. The mounting bracket 1 can be installed at the rear of the motor vehicle by using the mounting holes and bolts.

[0024] It should be noted that the self-locking electric push rod 11 is existing technology, and those skilled in the art can set it according to actual needs, which will not be elaborated here.

[0025] In this embodiment, the locking assembly includes two symmetrical fixing plates 8 welded to the top of the fixing frame 7. The fixing plates 8 are inclined, and a guide rod 10 is slidably connected inside the fixing plate 8. Both ends of the guide rod 10 pass through the fixing plate 8. A clamping block 6 is welded to one end of the guide rod 10. A threaded rod 9 is rotatably connected to one side of the clamping block 6 via a bearing. The threaded rod 9 is threadedly connected to the fixing plate 8. The inclination angle of the fixing plate 8 is 40 to 45 degrees. The inclination angles of the fixing plate 8, the threaded rod 9, and the guide rod 10 are equal. When the two threaded rods 9 are rotated, they will move inclinedly along the direction of the guide rod 10. The movement of the two threaded rods 9 will drive the clamping block 6 to move, so that the two clamping blocks 6 contact the camera and form a squeezing state, thereby achieving the fixed locking of the camera. Through the inclined threaded rod 9, its rotation trajectory forms a certain angle with the edge of the mounting frame 1. In this way, fingers or tools will not be obstructed by the narrow space of the mounting frame 1 during operation, which greatly improves the convenience of operation in a limited space.

[0026] In this application, the inner wall of the threaded hole of the fixing plate 8 that mates with the threaded rod 9 is provided with an annular groove. A nylon 66 damping ring with a Shore hardness of 85A is embedded in the groove. The continuous axial clamping force generated by its elastic deformation forms a helical angle interference fit with the surface of the threaded rod at 15°-20°. When the threaded pair is subjected to axial vibration load, the nylon insert can generate a maximum elastic compression of 0.3m, which increases the friction coefficient between the thread contact surfaces from 0.15 to 0.68 (tested according to ASTM D1894 standard), effectively suppressing loosening displacement caused by thread springback.

[0027] In this embodiment, an anti-slip pad is attached to the side of the clamping block 6 that contacts the camera. Multiple anti-slip patterns are provided on one side of the anti-slip pad. When the two clamping blocks 6 move toward the camera and clamp, the anti-slip pad can increase the friction between the anti-slip pad and the camera, thereby effectively preventing the camera from sliding or shifting during the fixing process.

[0028] In this embodiment, the transparent cover 4 is an arc-shaped tempered glass plate, which ensures that the transparent cover 4 has high strength and good light transmittance.

[0029] In this embodiment, a dustproof plate 2 is detachably connected to the inner wall edge of the mounting bracket 1 by bolts, and a through-hole 3 is provided on one side of the dustproof plate 2.

[0030] The use of this utility model involves the following steps:

[0031] S1: Rotate the two threaded rods 9 respectively. The threaded rods 9 will tilt and move along the direction of the guide rod 10. The movement of the two threaded rods 9 will drive the clamping blocks 6 to move, so that the two clamping blocks 6 contact the camera and form a squeezing state, thereby fixing and locking the camera.

[0032] S2: When it is necessary to adjust the angle of the camera, activate the self-locking electric push rod 11. The piston end of the self-locking electric push rod 11 drives the rack 13 to move left and right. When the rack 13 moves, it drives the gear 15 to rotate. The rotation of the gear 15 drives the connecting shaft 14 to rotate. The connecting shaft 14 then drives the fixing frame 7 to rotate. The fixing frame 7 drives the camera fixed on the fixing frame 7 to rotate, thereby realizing the adjustment of the camera angle to meet the shooting needs of different directions.

[0033] Finally, the following points should be noted: In the description of this application, it should be noted that, unless otherwise specified and limited, the terms "installation", "connection" and "linkage" should be interpreted broadly, and can be mechanical or electrical connection, or internal connection between two components, or direct connection. "Up", "down", "left", "right", etc. are only used to indicate relative positional relationship. When the absolute position of the described object changes, the relative positional relationship may change.
