The invention discloses a back-off type deep-drawing movable nut plate, which relates to the technical field of vehicle parts and comprises a deep-drawing nut plate, a back-off type deep-drawing movable nut plate, a battery pack mounting bolt, a vehicle body longitudinal beam assembly and a BEV vehicle body longitudinal beam framework assembly. According to the invention, the battery pack mounting nut which is arranged in the longitudinal beam of the vehicle body in a projection welding manner is designed into the movable nut plate assembly, so that the problem of high-precision assembly of the battery pack with large weight and large size of a pure electric BEV model is solved; the nut buried in the movable nut plate is designed to be a deep-drawing nut, and the requirement for large installation torque of an opponent bolt is met. The base wrapping the deep drawing nut in the movable nut plate is designed to be of an inverted buckling type closed structure, and the risk that the movable nut plate of a vehicle body fails to be jacked up in the mounting and dismounting processes is avoided; the optimal deep-drawing nut outline optimization design is made through CAE analysis, and the risk that in traditional design, under the large-torque assembling condition of a hand part bolt, the side wall of a nut plate base is punctured by trimming of a movable nut plate, and 360-degree rotation is caused is avoided.

    本发明公开了倒扣型深冲活动螺母板,涉及车用零件技术领域,包括:深冲螺母板、倒扣型深冲活动螺母板、电池包安装螺栓、车身纵梁总成和BEV车型车身纵梁骨架总成。本发明将凸焊在车身纵梁内部的电池包安装螺母设计成活动螺母板组件,解决了纯电动BEV车型大重量、大尺寸电池包高精度装配问题;将埋在活动螺母板里的螺母设计为深冲螺母,解决了对手件螺栓大安装扭矩要求;将活动螺母板中包裹深冲螺母的底座,设计成一种倒扣型封闭结构,解决了车身活动螺母板安装及拆装过程中顶起失效的风险;通过CAE分析做最佳的深冲螺母轮廓优化设计,解决了传统设计中对手件螺栓大扭矩装配情况下,活动螺母板修边戳破螺母板底座侧壁,造成360度旋转的风险。
