Vehicle door structure without B column

Abstract

The invention relates to a B-pillar-free car door structure, and relates to the technical field of car design and manufacturing. The B-pillar-free vehicle door structure comprises the sliding door and the front door which can be opened at the same time, the opening degree is increased, freight transport is facilitated, the front door B pillar is arranged in the front door, and the sliding door B pillar is arranged in the sliding door; a window frame reinforcing plate is arranged on the side, close to the sliding door, of an inner window frame of the front door, an upper lock reinforcing plate is arranged on the upper portion of the window frame reinforcing plate, a transversely-arranged anti-collision beam is arranged on the lower portion in the front door, a vertically-arranged outer plate supporting plate is arranged between the window frame and the anti-collision beam, and a lower lock reinforcing plate is arranged on the side, close to the sliding door, of the lower side of the anti-collision beam. The upper end of the front door B column is opposite to the window frame reinforcing plate; and the lower end of the front door B column is opposite to the lower lock reinforcing plate. According to the B-pillar-free vehicle door structure, the performance of absorbing side collision energy is improved, the front door can be prevented from excessively invading into the vehicle during side collision by being matched with the arrangement of the safety hook, and multiple safety guarantees are formed.

Description

technical field [0001] The invention relates to the technical field of automobile design and manufacture, more specifically, the invention relates to a vehicle door structure without a B-pillar. Background technique [0002] With the development of the economy and the progress of the society, the current demand for cargo transshipment has reached its peak. Although the models of logistics transshipment are becoming more and more common, domestic logistics vehicles are still mainly loaded and unloaded with side sliding doors as the channel. There is some inconvenience in cargo transshipment. [0003] In order to better facilitate the loading and unloading of goods, the model without B-pillar came into being. Its advantage is that when the front door and the sliding door are opened at the same time, a huge cargo transfer channel will be formed, and relatively large cargo can be easily loaded and unloaded, thus Improve the convenience of loading, unloading and transshipment of...
