Buffering pressure relief mechanism used when rearview mirror electric folder returns to zero position

The utility model discloses a buffer pressure relief mechanism used when an electric folder of a rearview mirror returns to the zero position. The buffer pressure relief mechanism comprises a support and a lower cover. A connecting groove for placing the lower cover is formed in one side of the support, concave holes for placing the PINs are formed in the surface of the lower cover, springs for enabling the PINs to stretch out and draw back are welded in the PINs, connecting blocks are welded to one sides of the springs, and sliding grooves for enabling sliding blocks on one sides of the connecting blocks to slide are formed in the PINs; by means of the support, the lower cover, the spring, the connecting block and the PIN, the buffering pressure relief mechanism solves the problems that when an existing buffering pressure relief mechanism used when the rearview mirror electric folder returns to the zero position is used, impact shaking and impact noise are prone to occurring when a rearview mirror left piece
