Connection structure of retro-reflector and body

The invention discloses a connection structure of a retro-reflector and a body. The connection structure comprises a body sheet metal part which is disposed on the inner side and is integrally plate-shaped, and the retro-reflector which is mounted on the outer side of the body sheet metal part. A groove is formed in the outer surface of the body sheet metal part. The retro-reflector is mounted in the groove of the body sheet metal part. An outward flange is arranged on the periphery of the retro-reflector. The outer end of the flange gradually approaches the side wall of the groove and is at a position adjacent to the periphery profile of the groove of the body sheet metal part. At least one cushion block is arranged between the bottom of the groove of the body sheet metal part and the retro-reflector and is fixedly connected with the retro-reflector. By adopting the connection structure, the retro-reflector can be prevented from compressional deformation, and the appearance of the connection part of the retro-reflector and the body is improved. At the same time, the production difficulty is low, the manufacturing error is small, and the mounting is simple and convenient.
