The invention provides a stroller frame body structure and a stroller, and belongs to the technical field of strollers, the stroller frame body structure comprises: a base provided with a limiting groove; the first arm body is rotatably connected with the base; the second arm body is rotatably connected with the base; a first linkage part and a second linkage part are arranged at the two ends of the first connecting rod respectively; a third linkage part and a fourth linkage part are arranged at the two ends of the second connecting rod respectively; and the linkage piece penetrates through the second linkage part, the limiting groove and the fourth linkage part. The mechanical arm has the beneficial effects that when the first arm body rotates relative to the base, the first connecting rod drives the linkage piece to move in the length direction of the limiting groove, and the second connecting rod drives the second arm body to rotate relative to the base, so that the first arm body and the second arm body always keep the same rotation; and the condition that one of the two is accidentally opened after the folding is not easy to occur.
本发明提供了一种儿童推车架体结构以及儿童推车,属于儿童推车技术领域,包括:基座,其设置有限位槽;第一臂体,其可转动地与所述基座连接;第二臂体,其可转动地与所述基座连接;第一连杆,其两端分别设置有第一联动部以及第二联动部;第二连杆,其两端分别设置有第三联动部以及第四联动部;联动件,其穿过所述第二联动部、所述限位槽以及所述第四联动部。本发明的有益效果为:第一臂体相对于基座转动时通过第一连杆带动联动件沿限位槽的长度方向移动,并通过第二连杆带动第二臂体相对于基座转动,从而使第一臂体与第二臂体始终保持相同的转动,不易发生收折后两者的其中之一意外打开的情况发生。
