The auxiliary frame structure comprises an auxiliary frame arranged above a chassis longitudinal beam, the auxiliary frame comprises a bearing box, a cover plate and a transverse supporting beam, the bearing box stretches across the chassis longitudinal beam and is fixedly connected to the chassis longitudinal beam, and the transverse supporting beam stretches across the chassis longitudinal beam and is fixedly connected to the chassis longitudinal beam. The upper ends of the bearing box and the transverse supporting beam are fixedly connected with a cover plate, and the upper portion of the cover plate serves as an installation plane used for installing an upper loading carriage of the motor home. The bearing box fixedly connected to the longitudinal beam and the cover plate structure fixed to the bearing box are adopted by the auxiliary frame, the strength of the chassis longitudinal beam is improved, intricate frame structures are reduced, the structure is simple, the weight is light, the cost is low, the storage space utilization rate is high, batch production is convenient, and the production efficiency is improved; and the gravity center of the motor home is centered, so that the motor home runs more stably and safely.

    本发明公开了一种改装车副车架结构,包括设置在底盘纵梁上方的副车架,所述副车架包括承载箱、盖板和横向支撑梁,所述承载箱横跨底盘纵梁并固定连接在底盘纵梁上,所述横向支撑梁横跨底盘纵梁并固定连接在底盘纵梁上,所述承载箱和横向支撑梁的上端固定连接有盖板,所述盖板上方作为安装平面用于安装房车的上装车厢。本发明通过副车架采用固定连接在纵梁上的承载箱和固定在承载箱上的盖板结构,增加了底盘纵梁的强度,减少了错综复杂的框架结构,使得结构简洁,重量轻,成本低,存储空间利用率高,方便批量生产,提高生产效率;且房车重心居中,使得房车行驶更加稳定、安全。
