The utility model sets two embodiments for the rolling rotation matching part 8, the first kind refers to as shown in Figure 2 , Figure 3 , the rolling rotation matching part 8 comprises an upper plane washer 9 and a lower plane washer 10, the opposite end faces of the upper plane washer 9 and the lower plane washer 10 are provided with annular grooves, a plurality of steel balls 11 are distributed between the annular grooves, the lower plane washer 10 is arranged on the supporting tray 7 and is detachably connected with the supporting tray 7, the upper plane washer 9 is arranged on the lower end face of the stepped surface 3 and abuts against the stepped surface 3 through the lower plane washer 108 and the steel balls 11. The second kind refers to as shown inFigure 4 , Figure 5 As shown, the rolling and rotating fitting part 8 includes an upper washer 12 fixed to or integrally formed with the end face of the stepped surface 3 and a lower washer 13 fixed to or integrally formed with the support tray 7. Both the upper washer 12 and the lower washer 13 have annular grooves on their opposite end faces, and multiple steel balls 11 are distributed between the annular grooves. The two types of rolling and rotating fitting parts 8 can be selected according to actual production costs. Both types can increase the flexibility and smoothness of the mirror housing 1 during rotation, while reducing wear.

[0025] For reference Figure 1 , Figure 3 As shown, the bottom of the rotating fixing part 51 is a sphere 511 with a built-in cavity, and the upper end is a hollow rod 512 communicating with the cavity. The upper end of the hollow rod 512 passes through the stepped surface 3 and is connected to a reset mechanism 14. When the mirror housing 1 rotates about the rotating fixing part 51, the reset mechanism 14 is used to drive the mirror housing 1 to reset. The rotating fixing part 51 is connected to the extension part 2 and the reset mechanism 14 through a connecting mechanism 6. The connecting mechanism 6 includes a screw 61, a nut 62 and a spring 63. The spring 63 is sleeved on the screw 61 and distributed in the cavity. A washer is provided between the head of the screw 61 and the spring 63 to prevent the spring 63 from disengaging from the screw 61. The screw 61 passes through the extension part 2 and the reset mechanism 14 and is connected to the nut 62. At least one washer is provided between the nut 62 and the reset part. Specifically, the reset mechanism 14 includes a first reset block integrally formed with the upper connecting groove or a first reset block detachably connected to the upper connecting groove. The upper end surface of the first reset block is provided with a non-flat surface, and a second reset block is matched with the non-flat surface. Both the second reset block and the first reset block are provided with through holes in their centers. The second reset block is provided with a fan-shaped block that decreases in size from bottom to top in the corresponding fan-shaped notch in the through hole. A compensation block is also inserted at the fan-shaped block. The compensation block restricts the rotation of the compensation block by a vertical limiting block and a vertical limiting groove inside the through hole, thereby enabling the compensation block to move up and down. The compensation block is provided with a multi-shaped block corresponding to the fan-shaped notch. The multi-shaped block and the fan-shaped block are combined and fit against the fan-shaped notch. A gasket is also provided above the compensation block to compensate for the gap between the top of the compensation block and the upper end of the connecting mechanism 6, so that the compensation block can push the nut 62 to move upward. When the mirror housing 1 rotates due to a collision, the first reset block and the second reset block rotate upwards in a misaligned manner, and the compensation block moves upwards, thereby driving the screw 61 to move upwards. This causes the spring 63, which is confined in the cavity, to be in a compressed state. After the collision, the restoring force of the spring 63 itself will push the pad to move downwards, which in turn will cause the first screw 61 to move downwards. When the compensation block and the second reset block move downwards, a restoring force is generated. The first reset block, along with the mirror housing 1, returns to the original set angle around the hollow rod 512, so that the first reset block and the second reset block can be refitted.

[0026] like Figure 7As shown, in order to further increase the damping between the first reset block and the second reset block, the protrusions on the end face of the first reset block are provided with grooves, and the second reset block is provided with protrusions corresponding to the grooves. The cooperation of the recesses and protrusions increases the damping, so that the mirror shell 1 is not easily pushed under the action of external force.
