The invention discloses a car door anti-collision beam structure which comprises an anti-collision beam body and a concave reinforcing rib connected with the anti-collision beam body, the length of the concave reinforcing rib is smaller than that of the anti-collision beam body, and the concave reinforcing rib and the anti-collision beam body are integrally formed through a hot air expansion process. According to the vehicle door anti-collision beam structure, the side door anti-collision beam is formed into a thermal forming reinforcing structure with a closed section through a hot air expansion forming technology after the thermal forming plate is blanked, the rigidity of the anti-collision beam is improved through the closed section, and the safety of the side door in the side collision process is guaranteed; and the protection effect on passengers in the side collision process of the automobile door is improved. The invention further discloses a manufacturing method of the vehicle door anti-collision beam structure, a vehicle door assembly and a vehicle.
本发明公开了一种车门防撞梁结构,包括防撞梁本体和与防撞梁本体连接的内凹加强筋,内凹加强筋的长度小于防撞梁本体的长度,内凹加强筋和防撞梁本体为采用热气胀工艺一体成型。本发明的车门防撞梁结构,采用将热成型板材下料后卷管,通过热气胀成型技术,将侧门防撞梁成型为带封闭式截面的热成行加强结构,通过封闭截面提升防撞梁刚度,保证侧门在侧面碰撞过程中的安全性,提高车门在侧面碰撞过程中对乘员的保护作用。本发明还公开了一种车门防撞梁结构的制造方法、车门总成和车辆。
