Abstract

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.

Description

technical field [0001] The invention relates to the technical field of mobile robots, in particular to a four-wheel mobile robot chassis and a four-wheel mobile robot. Background technique [0002] With the continuous advancement of science and technology, smart equipment has gradually entered people's lives, replacing people with simple and repetitive tasks. For example, outdoor mobile robots can replace people in park inspections and outdoor item delivery, so it is necessary to design a chassis structure suitable for this type of mobile robot. [0003] Most of the existing schemes use four-wheel drive and four-wheel differential steering mobile chassis, which is suitable for indoor use. However, the outdoor road surface is relatively complicated, and the friction force of the four-wheel differential steering is relatively large, and the driving motor power required for turning is too large, resulting in high manufacturing costs, high power consumption, and short battery l...
