DETAILED DESCRIPTION

[0019] Please refer to Figures 1 to 6 ;

[0020] This embodiment provides a space-saving fixing structure for a camera PCB, including a lens holder 1 for installation and fixing and a PCB board 2 embedded and fixed therein. A positioning locking seat 12 is provided on the lens holder 1, and a rotatable positioning screw 3 is provided in the positioning locking seat 12. The positioning screw 3 is rotated to realize positioning, guiding and locking of the PCB board 2. A positioning locking hole 22 is opened on the PCB board 2.

[0021] Preferably, an anti-foolproof card table 11 is provided on one side of the inner cavity of the mirror base 1, and a cylindrical positioning locking seat 12 is provided at the upper left corner and the lower right corner of the inner cavity of the mirror base 1. A T-shaped cylindrical cavity-shaped rotating shaft cavity 13 is eccentrically provided in the positioning locking seat 12, and a spring cavity 14 is provided at the bottom of the rotating shaft cavity 13.

[0022] In a specific embodiment, a fool-proofing slot 21 corresponding to the fool-proofing slot 11 is provided on one side edge of the PCB board 2. The fool-proofing slot 21 and the fool-proofing slot 11 cooperate with each other to prevent the original components on the PCB board 2 from being damaged due to misplaced installation by personnel during installation.

[0023] Preferably, a PCB board 2 is sleeved on the positioning locking seat 12 of the mirror base 1, and an anti-foolproofing slot 21 corresponding to the anti-foolproofing card platform 11 is provided on one side edge of the PCB board 2, and penetrating positioning locking holes 22 are provided at the upper left corner and the lower right corner of the PCB board 2, and the positioning locking holes 22 are slidably sleeved on the positioning locking seat 12 of the mirror base 1.

The top of the positioning screw 3 is a positioning head 31 with a chamfered edge on the upper surface of the upper surface and a slotted notch. The diameter of the positioning head 31 is equal to the diameter of the positioning locking seat 12 of the mirror base 1. A T-shaped eccentric rotating shaft 32 is eccentrically provided on the bottom surface of the positioning head 31. The eccentric rotating shaft 32 is rotatably provided in the rotating shaft cavity 13 of the mirror base 1.

[0025] In a specific embodiment, the elastic force of the spring 4 provides a damping effect on the rotation of the eccentric shaft 32 of the positioning screw 3, thereby preventing the positioning screw 3 from idling without external force and causing the PCB board 2 to be disengaged.

[0026] Preferably, a spring 4 is provided in the spring cavity 14 of the mirror base 1 , and the spring 4 abuts against the bottom surface of the inner wall of the spring cavity 14 and the bottom surface of the eccentric shaft 32 of the positioning screw 3 .

The surface of the PCB board 2 is unobstructed, and the PCB board 2 is slidably sleeved on the outer wall of the positioning locking seat 12 for loading and unloading. When the PCB board 2 needs to be locked, a flat-bladed screwdriver is used to manually rotate the positioning head 31 of the positioning screw 3 to be eccentric with the positioning locking seat 12. The positioning head 31 is staggered with the positioning locking seat 12, and the positioning head 31 fixes the PCB board 2 on the positioning locking seat 12 to achieve locking.
