Suspension mechanism of mobile robot

Abstract

The invention relates to a suspension mechanism of a mobile robot. Suspension mechanisms are arranged between a vehicle body of the robot and wheels; the suspension mechanisms comprise upper arms andlower arms; hub seats rotationally connected with the wheels are arranged on the wheels; one end of the upper arms are hinged with the vehicle body; the other ends of the upper arms are hinged with the hub seats; the lower arms are arranged right under the upper arms; one ends of the lower arms are hinged with the vehicle body; and the other ends of the lower arms are hinged with the hub seats. According to the suspension mechanism of the mobile robot, by arranging the suspension mechanisms between the wheels and the vehicle body of the mobile robot, the mobile robot can adapt to bumpy road conditions in the moving process so that a vibration buffering and absorbing effect is realized and the moving stability of the robot is improved. The hinging points of the two ends of the upper arms and the hinging points of the two ends of the lower arms form a parallelogram so that the wheels are prevented from being suspended in the air and the road holding is kept. Universal joints are arrangedon the wheels and power pieces and are suitable for the suspension mechanisms to move up and down.

Description

technical field [0001] The invention relates to a robot, more specifically to a suspension mechanism of a mobile robot. Background technique [0002] The driving mechanism of the existing mobile robot has poor anti-collision performance, and the movement is extremely unstable when encountering a rigid collision during the movement. In addition, when moving on a slightly uneven ground, the entire robot is often stuck because the driving wheel has insufficient grip, the driving force is idling, and the movement is hindered. When moving on a bumpy road, the wheels have a greater impact on the car body, which will cause impacts on the parts inside the car body and shorten the life of the car body. Contents of the invention [0003] The object of the present invention is to overcome the defects of the prior art and provide a suspension mechanism of a mobile robot. [0004] To achieve the above object, the present invention adopts the following technical solutions: [0005] A...

[0002] The driving mechanism of the existing mobile robot has poor anti-collision performance. During the movement, when encountering a rigid collision, the movement is extremely unstable

Also, when moving on a slightly uneven ground, the entire robot is often stuck due to insufficient grip of the driving wheels, the driving force is idling, and the movement is blocked.

When moving on a bumpy road, the wheels have a greater impact on the car body, which will impact the parts inside the car body and shorten the life of the car body
