The invention relates to the technical field of mobile robots, and particularly discloses a four-wheel mobile robot chassis and a four-wheel mobile robot. The four-wheel mobile robot chassis comprisesa front steering wheel train, a rear driving wheel train, a frame body and a shock absorber; a first hinge seat is arranged at one end of the frame body, and the front steering wheel train is connected with the frame body through the first hinge seat; a second hinge seat is arranged at the other end of the frame body, and the rear driving wheel train is connected with the frame body through the second hinge seat; and the shock absorber is connected with the frame body, the front steering wheel train and the rear driving wheel train, the front steering wheel train swings up and down around thefirst hinge seat under the action of the shock absorber, and the rear driving wheel train swings up and down around the second hinge seat under the action of the shock absorber. According to the four-wheel mobile robot chassis, a non-independent suspension system is adopted, the hinge seat is additionally arranged between the suspension system and the frame body, and under the action of the spring shock absorber, it can be guaranteed that wheels evenly touch the ground when the chassis passes through a bumpy complex road condition.
本发明涉及移动机器人技术领域,具体公开一种四轮移动机器人底盘以及四轮移动机器人。四轮移动机器人底盘包括前转向轮系、后驱动轮系、车架体以及减震器;车架体的一端设有第一铰接座,前转向轮系通过第一铰接座与车架体连接;车架体的另一端设有第二铰接座,后驱动轮系通过第二铰接座与车架体连接;减震器与车架体、前转向轮系以及后驱动轮系连接,前转向轮系在减震器的作用下绕第一铰接座上下摆动,后驱动轮系在减震器的作用下绕第二铰接座上下摆动。本发明的四轮移动机器人底盘采用非独立悬挂系统,悬挂系统与车架体之间增加铰接座,在弹簧减震器的作用下,可使底盘在通过坑洼复杂路况时,保证车轮均匀着地。
