The invention belongs to the technical field of car trunks, and provides a car trunk lid inner plate assembly, a trunk, a car and a machining method.The car trunk lid inner plate is arranged to be a plastic plate which comprises a plurality of reinforcing ribs and is integrally formed in an injection molding mode, and on the basis that the reinforcing ribs meet the strength requirement, the reinforcing ribs are arranged on the plastic plate; compared with a mode of welding a steel plate or an aluminum plate, the plastic trunk lid inner plate obtained through integral injection molding has the advantages that the weight is greatly reduced, and the endurance mileage of an electric automobile can be increased; meanwhile, before injection molding of the trunk lid inner plate, the hinge reinforcing plate and the lock reinforcing plate are placed in an injection mold and integrally subjected to injection molding with the trunk lid inner plate, so that the size adaptation error of the joint of the trunk lid inner plate and other parts such as the hinge reinforcing plate and the lock reinforcing plate is reduced, and the strength and rigidity after connection are guaranteed; and the trunk lid inner plate can be obtained through an integral injection molding process.

    本发明属于车行李箱技术领域,提出了一种汽车行李箱盖内板总成、行李箱、汽车及加工方法,将行李箱盖内板设置为包括多个加强筋的一体注塑成型的塑料板,在加强筋保证强度要求的基础上,通过一体注塑成型得到塑料材质的行李箱盖内板,较焊接钢板或铝板的方式相比,极大的降低了重量,有利用于增加电动汽车的续航里程;同时,在行李箱盖内板注塑前,将铰链加强板和锁加强板放置在注塑模具内,与行李箱盖内板一体完成注塑成型,减小了李箱盖内板与铰链加强板和锁加强板等其他部件连接处的尺寸适配误差,保证了连接后的强度和刚度,为通过一体注塑成型工艺得到行李箱盖内板提供可能。
