The invention relates to the technical field of motor home carriages, in particular to an expandable van motor home which comprises a chassis, a carriage, a bed frame and a main bed board, the bed frame is arranged in the carriage, the main bed board is laid on the upper side of the bed frame, and an auxiliary bed board and a length expansion module are arranged at the tail of the carriage. When the length expansion module of the expandable van type motor home is expanded to the outer side of the carriage, the telescopic rod is driven by the length expansion module to extend out of the carriage along with the length expansion module and is used for providing supporting force for the auxiliary bed board, and the telescopic rod is installed in the bed frame and provides all the supporting force for the auxiliary bed board from the lower portion; the stress of the main bed board and the auxiliary bed board is all concentrated on the bed frame, and the length expansion module is not subjected to the load on the main bed board and the auxiliary bed board, so that the situation that the guide rail is easy to deform and derail after the length expansion module is excessively stressed or stressed for a long time is avoided, and the failure rate of the length expansion module is reduced; and the smoothness of the length expansion module during recovery is improved.

    本发明涉及房车车厢技术领域,具体为一种可拓展厢式房车,包括底盘、车厢、床架、主床板,床架设于车厢内,主床板铺设在床架上侧,车厢尾部设有副床板和长度拓展模块,本发明通过设置伸缩杆,可拓展厢式房车的长度拓展模块拓展至车厢外侧时,伸缩杆在长度拓展模块的带动下跟随长度拓展模块延伸至车厢外,并用于为副床板提供支撑力,由于伸缩杆安装于床架内且伸缩杆从下方提供给副床板全部的支撑力,主床板与副床板的受力全部集中在床架上,而长度拓展模块不受主床板和副床板上的负载,从而避免了长度拓展模块受力过大或长时间受力后容易出现导轨变形、脱轨的情况,降低长度拓展模块的故障率,提升长度拓展模块回收时的平顺性。
