Obstacle crossing assembly and obstacle crossing device

Abstract

The invention relates to the field of roller advancing structures, in particular to an obstacle crossing assembly and an obstacle crossing device. The obstacle crossing assembly comprises a wheel carrier, more than one driven wheel and more than one obstacle crossing wheel, wherein the driven wheels and the obstacle crossing wheels are rotationally installed on the wheel carrier. The obstacle crossing wheels are arranged in front of the advancing direction of the driven wheels, and the bottoms of the obstacle crossing wheels are higher than those of the driven wheels. The obstacle crossing wheels firstly contact with an obstacle, and the obstacle crossing wheels are easy to jump up the obstacle due to the high bottom surface, so that the driven wheels originally contacting with the groundare lifted to be separated from the ground, and the obstacle crossing effect is achieved. Through the assembly, the obstacle crossing performance is improved on the premise that the diameter of the driven wheel is not increased.

Description

technical field [0001] Embodiments of the present disclosure relate generally to the field of roller travel structures, and more particularly to obstacle clearance assemblies and obstacle clearance devices. Background technique [0002] At present, many traveling structures equipped with rollers need to consider the obstacle-crossing function on uneven road surfaces. The rollers usually have their own obstacle-breaking height, and the obstacle-breaking height of ordinary universal rollers is much smaller than its own wheel radius, about 1 / 4 The radius of one round is about 100%. To improve the obstacle surmounting performance, the radius of the wheel must be increased. However, in some application scenarios, the space is limited and the wheels with larger radius cannot be used. [0003] The problem of not being able to increase the radius of the roller has not been solved. Some universal wheels add a slope in front of the wheel to face the obstacle, so that the slope can sli...

Problems solved by technology

[0002] At present, many traveling structures equipped with rollers need to consider the obstacle-crossing function on uneven road surfaces. The rollers usually have their own obstacle-breaking height, and the obstacle-breaking height of ordinary universal rollers is much smaller than its own wheel radius, about 1 / 4 The radius of one round is about 100mm. To improve the obstacle-crossing performance, the radius of the wheel must be increased. However, in some application scenarios, the space is limited and it is impossible to use a wheel with a larger radius.

[0003] The problem of not being able to increase the radius of the roller has not been solved. Some universal wheels add a slope in front of the wheel to face the obstacle, so that the slope slides on the obstacle. There is no obvious improvement
