Abstract

The invention provides a linear suspension damping device for a chassis of a wheeled mobile robot. The linear suspension damping device comprises a suspension damping assembly for being connected with the robot chassis, and a motion assembly connected to the bottom of the suspension damping assembly. The suspension damping assembly comprises a support, a main motion shaft and an auxiliary motion shaft, and elasticity exists between the two ends of the support; the main motion shaft is arranged at one end of the support, the auxiliary motion shaft is arranged at the other end of the support, the top end of the main motion shaft and the top end of the auxiliary motion shaft are connected with the robot chassis, and the bottom end of the main motion shaft and the bottom end of the auxiliary motion shaft are kept to elastically make contact with the top face of the support; the motion assembly comprises a motor, a motor base and a wheel, wherein the motor, the motor base and the wheel are sequentially connected; the motor and the motor base are connected to the bottom face of the support, the motor is fixed below the auxiliary motion shaft, and the motor base is fixed below the main motion shaft; the main motion shaft is used for bearing impact generated after the wheel is subjected to road excitation; and the auxiliary motion shaft is used for buffering impact borne by the main motion shaft. The obstacle crossing capacity of the robot is improved, motion abrasion of an output shaft of the motor is relieved, and walking tends to be optimized.

Description

technical field [0001] The invention relates to the technical field of robots, in particular to a linear suspension shock absorbing device for a chassis of a wheeled mobile robot. Background technique [0002] At present, there are many kinds of robots. In terms of moving methods, they can be divided into wheeled, crawler, legged, snake-like, and jumping. Due to the advantages of large carrying capacity, fast walking speed, relatively convenient driving and control, wheeled mobile robots are widely used in various fields. The chassis of the wheeled mobile robot has the advantages of low noise, good stability, and fast walking speed. In particular, the use of mecanum wheels and omnidirectional wheels can realize all-round movements such as translation, in-situ rotation, and straight walking by controlling the drive motor. However, this type of mecanum wheel, omnidirectional wheel, and tubeless rubber wheel do not have a pneumatic inner tube. The wheel itself lacks elasticity...
