The invention relates to a four-wheel steering mechanism, which comprises a front wheel assembly, a rear wheel assembly and a linkage assembly. The linkage assembly comprises a first traction piece with a front end connected with the front wheel assembly and a rear end connected with the rear wheel assembly, and a second traction piece with the front end connected with the front wheel assembly andthe rear end connected with the rear wheel assembly. The front end of the first traction piece is located on the left side, the front end of the second traction piece is located on the right side, the rear end of the first traction piece is located on the right side, and the rear end of the second traction piece is located on the left side. According to the four-wheel steering mechanism, by arranging the linkage assembly, the front wheel assembly can drive the rear wheel assembly to steer in the opposite direction at the same time in the steering process, the overall turning radius of the four-wheel steering mechanism is greatly reduced, and therefore turning operation is more flexible. The four-wheel steering mechanism can be applied to various types of scooters, such as scooters, disabled scooters and knee scooters.
本发明涉及一种四轮转向机构,包括前轮组件后轮组件、联动组件,联动组件包括前端与前轮组件相连接且后端与后轮组件相连接的第一牵引件、前端与前轮组件相连接且后端与后轮组件相连接的第二牵引件,第一牵引件的前端位于左侧,第二牵引件的前端位于右侧,第一牵引件的后端位于右侧,第二牵引件的后端位于左侧。本四轮转向机构通过设置联动组件,使前轮组件在转向时能够带动后轮组件同时向着相反的方向转向,这样大大减小了四轮转向机构整体的转弯半径,从而使转弯操作更加灵活。本四轮转向机构可以应用于多种类型的代步车,如滑板车、残障车、膝盖代步车等。
