The invention provides a mobile platform off-road chassis and a mobile robot, and belongs to the field of intelligent motion platforms. The off-road chassis comprises a frame, a roller assembly, a steering assembly and driving assemblies. Rear cantilevers capable of swinging up and down relative to the frame are arranged at the rear end of the frame, and a shock absorber is connected between the frame and each rear cantilever. The roller assembly comprises front wheels and rear wheels, and each rear wheel is connected with one rear cantilever. The steering assembly is arranged at the front endof the frame and controls each front wheel to swing towards the two sides of the frame. Each rear wheel is correspondingly provided with a set of driving assembly, each set of driving assembly comprises a driving motor, a driving speed reducer and a telescopic universal joint which are in transmission connection in sequence, and the telescopic universal joints are in transmission connection withthe rear wheels. The mobile robot comprises a robot body and the off-road chassis. Rear wheel independent driving is matched with front wheel steering, and flexible steering is achieved through rear wheel active differential driving; and the rear wheels are matched with the telescopic universal joint and the rear suspension, and are supported and damped through the dampers, so that the steering stability and the obstacle crossing capability are improved.

    本申请提供一种移动平台越野底盘及移动机器人,属于智能运动平台领域。该越野底盘包括车架、滚轮组件、转向组件及驱动组件。车架后端设有能相对车架上下摆动后悬臂,车架与每个后悬臂之间均连接减震器。滚轮组件包括前轮及后轮,每个后轮与一个后悬臂连接。转向组件设置于车架前端,控制每个前轮朝向车架两侧摆动。每个后轮对应设置一组驱动组件,每组驱动组件包括依次传动连接的驱动电机、驱动减速机以及伸缩万向节,伸缩万向节与后轮传动连接。移动机器人包括机器人主体及该越野底盘。后轮独立驱动配合前轮转向,通过后轮主动差速驱动实现灵活转向;后轮与伸缩万向节及后悬架配合,通过减震器支撑和减震,利于提高转向稳定性及越障能力。
