The invention relates to the field of vehicle body structures, and discloses an upper and lower vehicle body screw joint structure for a lightweight vehicle body, which comprises an upper vehicle body and a lower vehicle body, the upper vehicle body and the lower vehicle body are connected and fixed through bolts so as to reduce the welding process, the lower vehicle body is platform-shaped, and the upper vehicle body can directly share the lower vehicle body after being remodeled. The upper vehicle body and the lower vehicle body are connected and fixed through the bolts, the upper vehicle body can directly share the lower vehicle body after being remodeled, it means that the design of the vehicle can be divided into an upper body design part and a lower body design part, and the upper body design part can be redesigned or upgraded without affecting the lower body; therefore, the production cost can be reduced, the manufacturing efficiency can be improved, and meanwhile, the stability and the consistency of the lower body design can be kept; by means of the design, more freedom degrees and flexibility can be provided for automobile manufacturers so as to cope with constantly changing market requirements and consumer preferences.

    本申请涉及车体结构领域,公开了一种用于轻量化车身的上下车体螺接结构,包括上车体和下车体,所述上车体和下车体之间通过螺栓连接固定,以减少焊接工艺,所述下车体呈平台化,所述上车体改款后能直接共用所述下车体。本发明通过上车体和下车体之间通过螺栓连接固定,上车体改款后能直接共用下车体,意味着车辆的设计可以分为上身设计和下身设计两部分,上身设计部分可以进行重新设计或升级而不会影响到下身,这样就可以在减少生产成本和提高制造效率的同时,也可以保持下身设计的稳定性和一致性;这种设计也可以为汽车制造商提供更多的自由度和灵活性,以应对不断变化的市场需求和消费者的偏好。
