The invention provides a reinforcing structure at a vehicle door hinge, and belongs to the technical field of machinery. The reinforcing structure solves the problems that in front collision or smalloffset collision of an existing reinforcing structure, deformation of an A pillar is too large, welding spots fail, and a metal plate is torn. The reinforcing structure at the vehicle door hinge comprises a reinforcing plate arranged at an installation position of a vehicle door A pillar hinge, the reinforcing plate is provided with at least one first protruding part arched towards one side and further provided with at least one second protruding part arched towards the other side, and the first protruding parts and the second protruding parts are distributed in the length direction of the reinforcing plate. According to the reinforcing plate, the first protruding parts and the second protruding parts are arranged such that by means of the structure, extrusion force can be transmitted anddispersed, stress concentration at the position is avoided, and therefore the problems of welding spot failure and metal plate tearing at the position are avoided, deformation of the A pillar in the collision process is reduced, the integrity of the passenger compartment structure is guaranteed, and the safety performance is effectively improved.
本发明提供了一种车门铰链处的加强结构,属于机械技术领域。它解决了现有的加强结构在前部碰撞或小偏置碰撞中容易造成A柱下变形过大而导致焊点失效及钣金撕裂的问题。本车门铰链处的加强结构,包括用于设置在车门A柱铰链安装处的加强板,加强板上具有至少一个向一侧拱起的凸起部一,加强板上还具有至少一个向另一侧拱起的凸起部二,凸起部一和凸起部二沿加强板的长度方向分布。本加强板通过凸起部一和凸起部二的结构设置,能够通过本身的结构将该挤压力传递分散,避免在该处实现应力集中,从而避免了该处焊点失效及钣金撕裂的问题,减小了A柱在碰撞中的变形,保证了乘员舱结构的完整性,有效的提升了安全的性能。
