The chassis structure comprises a chassis, a first rotating part, a second rotating part, a third rotating part, a fourth rotating part and a swing rod, the first rotating part and the second rotating part are connected to the chassis, the middle of the swing rod is in lever connection with the chassis, the third rotating part is connected to one end of the swing rod, and the fourth rotating part is connected to the other end of the swing rod. The fourth rotating piece is connected to the other end of the swing rod. At least one of the first rotating piece, the second rotating piece, the third rotating piece and the fourth rotating piece comprises a steering wheel, and at least one of the first rotating piece, the second rotating piece, the third rotating piece and the fourth rotating piece comprises a universal wheel. Wherein the third rotating part and the fourth rotating part are connected to the chassis through a swing rod, and when the load is increased, the swing rod can swing, so that the load pressure can be distributed to steering wheels in the first rotating part, the second rotating part, the third rotating part and the fourth rotating part, and the pressure between the steering wheels and the ground is increased along with the increase of the load; therefore, the driving force of the steering wheel is increased and the driving efficiency is improved.
本发明提供了一种底盘结构及运载机器人,底盘结构包括底盘、第一转动件、第二转动件、第三转动件、第四转动件及摆杆,第一转动件和第二转动件连接在底盘上,摆杆中部与底盘形成杠杆连接,第三转动件连接在摆杆的一端,第四转动件连接在摆杆的另一端;第一转动件、第二转动件、第三转动件和第四转动件中,至少一者包含有舵轮以及至少一者包含万向轮。其中,第三转动件和第四转动件通过摆杆连接在底盘,随负载增加时,摆杆能够摆动,使得负载压力分能够分布至第一转动件、第二转动件、第三转动件和第四转动件中的舵轮上,并且舵轮与地面之间的压力随着负载的增大而增大,进而舵轮的驱动力而增大,提高驱动效率。
