The invention discloses a patch plate engine cover inner plate, an automobile and a manufacturing method. The manufacturing method comprises the following steps: obtaining an inner plate material sheet of an engine cover and two hinge reinforcing plate material sheets, pre-fixing the two hinge reinforcing plate material sheets at the two ends of the inner plate material sheet respectively to form a basic inner plate, and using a hot forming stamping process to make the basic inner plate to form the patch plate engine cover inner plate body. According to the manufacturing method of the patch plate engine cover inner plate, the hinge reinforcing plate material sheets and the inner plate material sheet of the engine cover hinge are combined into a whole, the number of dies, detection tools and clamps is effectively reduced, meanwhile, the part machining precision is improved, the weight of an engine cover assembly is reduced, light weight is achieved, the strength of the hinge position of the engine cover inner plate is improved, and the performance of an engine cover assembly is improved.

    本发明公开了一种补丁板发动机盖内板、汽车及制造方法,包括:获取发动机盖的内板料片和两个铰链加强板料片,将两个铰链加强板料片分别在内板料片的两端进行预固定,构成基础内板,采用热成型冲压工艺使基础内板形成补丁板发动机盖内板本体,该补丁板发动机盖内板制造方法将发动机盖铰链的铰链加强板料片与内板料片结合为一体,有效减少模具、检具和夹具数量,同时提高零件加工精度,降低发动机盖总成重量,实现轻量化,增加了发动机盖内板铰链处强度,提升发动机盖总成性能。
