Door lock reinforcing plate for automobile tail door

Abstract

The invention relates to a door lock reinforcing plate for an automobile tail door. The door lock reinforcing plate comprises a reinforcing plate body which is used for being fixedly connected to an inner plate of the automobile tail door, the reinforcing plate body is bent to form a lower side plate, a middle plate and an upper side plate, the lower side plate is provided with a door lock arranging hole for arranging a tail door lock and a door lock fixing hole, the two ends of the middle plate extend horizontally to form horizontal extending strips, the side edge of the upper side plate extends upwards to form a V-shaped extending strip, mounting holes used for connection of the inner plate of the automobile tail door and an outer plate of the automobile tail door are formed in the reinforcing plate body, the horizontal extending strips and the V-shaped extending strip, and the reinforcing plate body, the horizontal extending strips and the V-shaped extending strip are mounted on a tail door structure through bolts; plastic-coated gum flowing holes used for being connected with the inner plate of the automobile tail door are formed in the reinforcing plate body, the horizontal extending strips and the V-shaped extending strip. According to the structure of the door lock reinforcing plate, the problem of insufficient rigidity of the automobile tail door is solved, the fatiguelife of mounting regions is prolonged when the door is opened and closed repeatedly, the application range is wide, and the door lock reinforcing plate can be used in structures of various automobiletail doors.

Description

technical field [0001] The invention relates to a reinforcing plate for automobiles, in particular to a door lock reinforcing plate for tailgates of automobiles. Background technique [0002] At present, most of the existing automobile door lock reinforcement plates are designed as L-shaped bending surfaces, one surface of the L-shaped bending is connected with the inner panel of the car door, and the other surface is connected with the inner panel of the car door and the door lock assembly. In the process of opening and closing the door, relatively large stress concentration is likely to occur at the chamfer of the inner door panel interface, and due to the insufficient fatigue strength of the door inner panel, cracks are prone to appear at the chamfer of the inner door panel interface. When cracks appear in the inner panel of the car door, the stiffness and fatigue durability of the inner panel of the door are generally improved by adding reinforcement plates locally, but ...
