Automobile lightweight door frame assembly

Abstract

The invention discloses an automobile lightweight door frame assembly, relates to the technical field of automobile accessories, and solves the problems that an existing automobile door frame and an anti-collision frame are prone to being impacted to fall off and penetrate through an interior trim panel of an automobile door to stab and injure a driver and passengers, and the anti-collision safety coefficient is poor. The automobile lightweight door frame assembly comprises a door frame, the door frame comprises L-shaped mounting bases, the upper half portion of the door frame is of a triangular arc-shaped structure, the lower half portion of the door frame is of a rectangular arc-shaped bent structure on the left side and the right side, and four L-shaped mounting bases are symmetrically arranged on the lower half portion of the door frame in a stamped mode. Two transverse supporting steel pipes are symmetrically welded and fixed to the four L-shaped mounting bases, and the length of the two transverse supporting steel pipes is two thirds of the width of the door frame; two hexagonal vertical supporting shafts are symmetrically welded to the middle sections of the two transverse supporting steel pipes in a penetrating mode. The end faces of the backs of the four mounting plates are flat, the four mounting plates are located on the same horizontal plane, and sound insulation cotton can be unfolded and mounted more conveniently.

Description

technical field [0001] The invention relates to the technical field of auto parts, in particular to an automobile lightweight door frame assembly. Background technique [0002] In general, a door frame of a vehicle is a window frame mounted to the door. That is, the door frame of the vehicle is a frame formed to surround the door glass. Further, a door glass run is installed at a door frame of a vehicle to guide opening / closing of a door glass. [0003] Whether it is the research and development of traditional fuel vehicles or new energy vehicles, especially electric vehicles, it is required to control or even reduce the weight of the vehicle to ensure that the vehicle has better acceleration and braking performance and reduces fuel consumption. , improve the cruising range; make the whole vehicle have better driving pleasure and handling fun. With the wave of new energy vehicles, electric vehicles have become a new force. How to improve the car door when the existing batt...
