Radial telescopic wheel mechanism capable of adapting to stair steps with different heights

Abstract

The invention discloses a radial telescopic wheel mechanism capable of adapting to stair steps with different heights. The wheel mechanism comprises a vehicle body connecting seat, a driving combinedshaft, a radial telescopic quadrangular wheel and a telescopic adjusting combined piece; the vehicle body connecting seat is connected with a vehicle frame body; the driving combined shaft comprises ahollow transmission shaft and a solid transmission shaft, the hollow transmission shaft is hinged with the vehicle body connecting seat, and the solid transmission shaft is hinged in the hollow transmission shaft; the radial telescopic quadrangular wheel comprises a four-caster frame capable of stretching out and drawing back in the radial direction and Mecanum wheels arranged at the ends of fourfeet of the four-caster frame; the four-caster frame is fixedly connected with the hollow transmission shaft, and the Mecanum wheels are in transmission fit with the solid transmission shaft; the telescopic adjusting combined piece comprises a brake mechanism arranged between the vehicle body connecting seat and the hollow transmission shaft and a brake adjusting mechanism arranged between the vehicle frame body and the four-caster frame. The wheel mechanism can adapt to the height change of stair steps, and the safety and stability of stair climbing equipment in use are improved.

Description

technical field [0001] The invention belongs to the technical field of vehicle wheels, and in particular relates to a radially telescopic wheel mechanism that can adapt to stair steps of different heights. Background technique [0002] Stair cleaning robots often use triangular or quadrangular wheel frames with mecanum wheels to realize stair climbing and lateral movement on stair steps; none of the wheel frames using mecanum wheels in the prior art has the function of radial telescopic adjustment ; When cleaning the stairs, it cannot adapt to the changes of the stairs of different heights. After the height of the stairs changes, it is easy for the robot to slip off the stairs and cannot climb, resulting in unsafe, unstable, and poorly designed stair cleaning robots. The function of can not be brought into play effectively; Therefore, it is necessary to improve existing technology. Contents of the invention [0003] The purpose of the present invention is to address the d...
