Description

Technical Field

[0001] The utility model relates to the technical field of aluminum-based vehicle bodies, in particular to a door opening stop structure of an aluminum-based vehicle body. Background Art

[0002] At present, the body frames on the market are mainly made of steel bodies. The structure of the stop part of the traditional steel body is composed of the stamping parts of the side outer panel assembly and the side inner panel assembly, which are spot-welded and matched to form the structural design of the door opening stop. However, since the aluminum body frame is composed of overlapping aluminum profiles, the stop flange of the aluminum body cannot be formed synchronously with that of the steel body.

[0003] For example, Chinese patent CN112441132A discloses a method for connecting a vehicle threshold to a vehicle body, which includes a threshold inner panel, a threshold outer panel and a support plate. The threshold inner panel is a steel sheet metal part, the threshold outer panel is an aluminum profile threshold, and the support plate is located between the threshold outer panel and the threshold inner panel. The threshold inner panel, the threshold outer panel and the support are fixedly connected to form an integrated structure, and the edge of the threshold inner panel forms a stop structure. The stop structure can be formed by flanging, but its structural strength is relatively weak. Utility Model Content

[0007] Further:

[0008] The invention also comprises a threshold beam aluminum profile, on which a threshold stop is extruded and formed integrally.

[0009] The B-pillar assembly is a separate sheet metal structure, and the end of the B-pillar assembly is riveted and fixed to the side frame of the vehicle body.

[0010] The front stop of the front door opening includes a pair of sheet metal parts whose edges are welded to form the stop, a flange structure is formed on the inner side of the sheet metal part, and the flange structure is welded to the A-pillar profile of the vehicle body.

[0012] The rear stop of the rear door opening includes a pair of sheet metal parts whose edges are welded to form the stop, a flange structure is formed on the inner side of the sheet metal part, and the flange structure is welded to the C-pillar profile of the vehicle body.

[0013] Adjacent stoppers of the door opening stopper structure are spliced ​​and welded to each other.
