Description

B-pillar structure of a two-seat frameless door car

technical field

The utility model relates to the field of vehicle production and manufacturing, in particular to a B-pillar structure of a two-seat frameless door car.

Background technique

Frameless windows generally appear on sports cars or sports cars, especially convertible sports cars. Frameless door technology appeared at the end of the last century. It has a wider vision, is very elegant, trendy and individual, but this technology has not been popularized for a long time, and it has been transferred to ordinary sports cars. The safety performance is lower than that of a framed door, and the side impact performance is worse than that of a framed door.

Due to the lack of a frame in the frameless car door, the door bears less force during a side impact, so the B-pillar bears a greater force than a conventional door during a side impact, which requires that the B-pillar structure of the frameless door must have sufficient strength At the same time, because it is a two-seater car, the distance between the rear butterfly window and the B-pillar is relatively close, and it is impossible to provide a mounting surface for the rear butterfly window while taking into account the impact strength of the B-pillar, resulting in a structural overlap between the B-pillar and the rear butterfly window. problem.
