The invention relates to the technical field of automobile body parts, and discloses an automobile door outer protective plate structure, an automobile door and an automobile. The automobile door outer protective plate structure comprises an outer protective plate and an automobile door metal plate, a gap is formed between the outer protective plate and the automobile door metal plate, and a rigid body is arranged in the gap between the outer protective plate and the automobile door metal plate; the side, close to the outer protection plate, of the rigid body makes contact with the outer protection plate, the side, close to the automobile door metal plate, of the rigid body makes contact with the automobile door metal plate, a plurality of through holes and/or grooves are formed in the rigid body, and the shapes of the through holes and/or the grooves comprise one or more combinations of a circle, a polygon and an irregular shape. The rigid body is arranged in the gap between the outer protective plate and the automobile door metal plate, when collision occurs, collision force colliding with the outer protective plate can be directly transmitted to the automobile door metal plate through the rigid body and then transmitted to the doorsill beam, in the whole process, the transmission stroke of the thickness of the rigid body is shortened, and therefore the transmission time of the collision force can be shortened, and the transmission efficiency is improved. And the explosion time of the air bag is close to the collision time.
本发明涉及汽车车身零部件技术领域,公开了一种车门外护板结构、车门及车辆,车门外护板结构包括外护板和车门钣金,外护板与车门钣金之间具有间隙,外护板与车门钣金之间的间隙内设有刚性体,刚性体靠近外护板的一侧与外护板接触,刚性体靠近车门钣金的一侧与车门钣金接触,刚性体上设有若干通孔和/或凹槽,通孔和/或凹槽的形状包括圆形、多边形和不规则形状的一种或者多种组合。本发明在外护板与车门钣金之间的间隙中设置刚性体,当发生碰撞时,碰撞到外护板的碰撞力可以通过刚性体直接传递到车门钣金,再传递到门槛梁,整个过程中,缩短了刚性体厚度的传递行程,从而就可以缩短碰撞力的传递时间,使得气囊的点爆时间接近碰撞发生时的时间。
