The invention discloses an engine cover inner plate and a vehicle, and belongs to the technical field of automobile parts. The engine cover inner plate comprises an engine cover inner plate body, a plurality of rib beams and a plurality of welding spots, the engine cover inner plate body is of an annular structure, the engine cover inner plate body of the annular structure surrounds to form a mounting area, the rib beams are located in the mounting area, and the welding spots are connected with the engine cover inner plate body and the rib beams respectively. Both the engine cover inner plate body and the rib beam can be made of high-hardness materials, under the normal condition of a vehicle, the engine cover inner plate body and the rib beam are connected through the welding spots, the engine cover inner plate body and the rib beam which are high in hardness guarantee the performance requirements for rigidity and concave resistance of the engine cover inner plate, under the condition that the head of a pedestrian collides with the engine cover inner plate, the welding spots fail, and the engine cover inner plate cannot be damaged. The rib beam falls off from the engine cover inner plate body to avoid the head of a pedestrian, so that the damage of the engine cover inner plate to the head of the pedestrian is effectively reduced, and the two requirements of the engine cover inner plate for rigidity, concave resistance and protection of the head of the pedestrian are met at the same time.
本公开是一种发盖内板及车辆,属于汽车零部件技术领域。发盖内板包括发盖内板本体、多个筋梁和多个焊点,发盖内板本体具有环形结构,环形结构的发盖内板本体环绕形成安装区域,多个筋梁位于安装区域,焊点分别与发盖内板本体、筋梁相连。发盖内板本体与筋梁均可以采用硬度较高的材质,在车辆的正常情况下,发盖内板本体与筋梁通过焊点相连,硬度较高的发盖内板本体与筋梁保证了发盖内板自身刚度、抗凹的性能需求,在行人头部撞击发盖内板的情况下,焊点失效,筋梁从发盖内板本体上脱落以避让行人头部,进而有效降低发盖内板对行人头部的伤害,从而同时兼顾了发盖内板自身刚度、抗凹性能和对行人头部保护两种需求。
