The invention provides a car lower platform capable of expanding in the Z direction, the car lower platform comprises a car frame structure and a floor structure, the floor structure comprises a cabin floor, the car frame structure comprises a middle car frame, a front car frame and a rear car frame, and the front car frame and the rear car frame are symmetrical relative to the middle car frame; two sides of the Y direction opposite to the automobile body are arranged in parallel; the two ends of the transverse support are adjacently connected between the longitudinal supports to form a frame structure, and the transverse support is used for being connected and fixed in the X direction through connecting pieces; wherein the cabin floor and the battery upper cover plate are integrated, the cabin floor and the battery upper cover plate are used for sealing the upper side of the frame body structure to form a battery containing cavity for containing a battery cell and bearing a cabin at the same time, and the middle-area vehicle frame is independently arranged relative to the front vehicle frame and the rear vehicle frame of the vehicle frame structure. And meanwhile, the middle-area frame adopts a frame body structure which is enclosed by longitudinal brackets and transverse brackets and has a flattened surface, so that a larger design space is reserved in a cabin, Z-direction expansion is realized, and the whole frame structure has high universality.

    本发明提供了一种可Z向拓展的汽车下平台,所述汽车下平台包括车架结构、地板结构,所述地板结构包括座舱地板,所述车架结构包括中区车架及相对中区车架对称的前车架、后车架:所述中区车架包括:纵向支架,平行设置相对汽车车身Y向的两侧;横向支架,所述横向支架两端邻接在纵向支架之间形成框体结构,用于通过连接件在X向连接固定;其中,所述座舱地板和电池上盖板集成化一体,用于封闭框体结构的上侧形成放置电芯的电池容腔同时承载座舱,且所述中区车架相对于车架结构的前车架、后车架分别独立设置。同时中区车架采用纵向支架和横向支架围合成表面平整化的框体结构,给舱内预留更大的设计空间,实现Z向可拓展,使得整体的车架结构具备高通用率。
