The light-weight inverted tricycle frame structure comprises a chassis frame and a front cabin frame, and the front cabin frame is arranged above the front portion of the chassis frame. Wherein the chassis frame comprises a main beam left pipe and a main beam right pipe which are symmetrically arranged left and right, the main beam left pipe and the main beam right pipe penetrate through the whole vehicle body after being transversely bent and longitudinally bent, and a first cross beam, a second cross beam, a third cross beam, a fourth cross beam and a fifth cross beam which are arranged at intervals in the length direction of the vehicle body are connected between the main beam left pipe and the main beam right pipe; the forecabin frame comprises four round vertical pipes connected to the chassis frame, the tops of the four round vertical pipes are connected with a forecabin transverse round pipe bent to be in a U shape, the rear end of the forecabin transverse round pipe is connected with a direction pipe column round pipe with the middle arched upwards, and the middle of the forecabin transverse round pipe is connected with a transverse supporting frame. The inverted tricycle frame has the beneficial effects that the inverted tricycle frame is simple but not simple in structure, light weight is achieved while the structural strength is met, functional positions are complete, assembly is easy, layout is reasonable, and maintenance is easy.
本发明公开了一种轻量化倒三轮车架结构,包括底盘框架和前舱框架,前舱框架设置于底盘框架前部上方;其中底盘框架包括左右对称布置的主梁左管和主梁右管,主梁左管和主梁右管经过横向弯折和纵向弯折后贯穿整个车身,主梁左管和主梁右管之间连接有沿车身长度方向间隔布置的第一横梁、第二横梁、第三横梁、第四横梁、第五横梁,前舱框架包括连接在底盘框架上的四个圆立管,四个圆立管顶部连接有弯折呈U型的前舱横圆管,前舱横圆管后端连接有中部向上拱起的方向管柱圆管,前舱横圆管中部连接有横向支撑架,本发明的有益效果包括:本倒三轮车架结构简约而不简单,在满足结构强度的同时实现了轻量化,功能位齐全,且装配简单,布局合理,易维修。
