M-shaped anti-collision beam structure of thermoformed front door

Abstract

The invention discloses an M-shaped anti-collision beam structure of a thermoformed front door and belongs to the field of automobile anti-collision beams. The anti-collision beam structure comprisesan anti-collision beam base body, a main frame and reinforcing ribs. A first welding spot is arranged at one end of the anti-collision beam base body; a second welding spot is arranged at the other end of the anti-collision beam base body; a first groove and a second groove are sequentially formed in the surface of the anti-collision beam base body; the main frame is welded to the surface of the anti-collision beam base body, and the main frame is arranged between the first groove and the second groove; a first threaded groove is formed in one end of the main frame; and a second threaded groove is formed in the other end of the main frame. The overall structure is simplified, the anti-collision performance is high, the welding technological process is reduced, and the installation efficiency is effectively improved.

Description

technical field [0001] The invention relates to the field of automobile anti-collision beams, in particular to an M-shaped anti-collision beam structure for a thermoformed front door. Background technique [0002] The front door anti-collision beam, also known as the door anti-collision beam, refers to the addition of a beam to the internal structure of the door to strengthen the structure of the side of the vehicle, thereby improving the anti-collision resistance during side impact, and improving the safety of the side. . [0003] At present, the front door anti-collision beam of most models adopts the tubular anti-collision bar and the front and rear brackets to weld the anti-collision bar assembly through carbon dioxide shielded welding. This structure will add a sequence of carbon dioxide shielded welding welding, and a total of three parts are welded through carbon dioxide shielded welding. It is difficult to ensure the welding accuracy; and the two front and rear shee...

Problems solved by technology

[0003] At present, the front door anti-collision beam of most models adopts the tubular anti-collision bar and the front and rear brackets to weld the anti-collision bar assembly through carbon dioxide shielded welding. This structure will add a sequence of carbon dioxide shielded welding welding, and a total of three parts are welded through carbon dioxide shielded welding. It is difficult to ensure the welding accuracy; and the two front and rear sheet metal brackets are opened more, the process is complicated and the cost is increased, and it is not convenient for the on-site workers to apply the vibration isolation glue on the outer panel of the door, and the design cannot be matched with the outer panel, and even worse Need to add additional welding glue bracket

At the same time, the cross section of the entire assembly of the existing anti-collision beam is not equal, which is easy to form stress concentration and lacks anti-collision performance
