The invention relates to the technical field of mobile vehicles, and discloses an adjustable rear wheel expansion device which comprises a device body. A front case; a rear housing; the connecting assembly is arranged between the front shell and the rear shell, one end of the connecting assembly is slidably connected with the front shell in the front-back direction, and the other end of the connecting assembly is fixedly connected with the rear shell; the first rear wheel assembly and the second rear wheel assembly are arranged on the two opposite sides of the rear shell respectively; the expansion assembly can apply a first acting force to the first rear wheel assembly and the second rear wheel assembly, the first acting force enables the first rear wheel assembly and the second rear wheel assembly to move oppositely, and the expansion assembly can apply a second acting force to the first rear wheel assembly and the second rear wheel assembly; the second acting force enables the first rear wheel assembly and the second rear wheel assembly to move relatively. Adjustment of the distance between the rear wheels is achieved, and the performance of the device in the aspects of the stability and the bearing capacity of the rear wheels is improved.

    本发明涉及移动交通工具技术领域,公开了一种可调节后轮扩展装置,包括:装置本体;前壳;后壳;连接组件,设置在前壳与后壳之间,连接组件的一端和前壳在前后方向上滑动连接,连接组件的另一端与后壳固定连接;第一后轮组件和第二后轮组件,后壳的相对两侧分别设有第一后轮组件和第二后轮组件;扩展组件,扩展组件可对第一后轮组件和第二后轮组件施加第一作用力,第一作用力使得第一后轮组件和第二后轮组件相背运动,且扩展组件可对第一后轮组件和第二后轮组件施加第二作用力,第二作用力使得第一后轮组件和第二后轮组件相对运动。本发明实现了后轮间距的调节,提高了装置在后轮稳定性和承载能力方面的性能。
