CN2835466Y - Reinforced piece structure for car back-door lock - Google Patents

Abstract

The utility model discloses a reinforced piece structure for a car back door lock. A reinforced piece for the back door lock is provided with a welded nut for installing the back door lock. A bent L shape of 90 DEG is formed between the bottom surface and the back surface of the reinforced piece for the back door lock. The bottom surface and the back surface are stuck to the inner skin of the back door. Thus, the bottom surface and the back surface can be connected with the inner skin of the back door in a weld spot mode on a plurality of surfaces. In addition, a flanging structure is also designed on the front end of the reinforced piece for the back door lock for reinforcing self-strength. The welding strength between the reinforced piece and the inner skin of the back door can be increased by adopting the structure. Meanwhile, the self-strength of the reinforced piece is enhanced.
