Title:
LOCOMOTION CHASSIS FOR ROBOT
Document Type and Number:
WIPO Patent Application WO/2023/045091
Kind Code:
A1
Abstract:
A locomotion chassis for a robot, comprising a chassis (1), a rack (2), adjustment mechanisms (4), follower wheel sets (5), and a steering mechanism (6). The rack (2) is fixedly connected to the upper end of the chassis (1). By means of the provision of the adjustment mechanisms (4), propulsion cylinders (42) are used to drive fixing frames (43) to deflect, so that the state of first rollers (45) and anti-skid wheels (44) is transitioned from the first rollers (45) being in contact with the ground and the anti-skid wheels (44) being in a suspended state to the first rollers (45) leaving the ground and the anti-skid wheels (44) being in contact with the ground. When the propulsion cylinders (42) work, the first rollers (45) gradually deflect upwards along with the deflection of the fixing frames (43) and then leave the ground, and the anti-skid wheels (44) gradually approach the ground along with the deflection of the fixing frames (43) until the anti-skid wheels (44) are in contact with the ground, thereby completing an adjustment function, and in this case, the first rollers (45) are suspended and the anti-skid wheels (44) work, thereby avoiding the problem that a robot may skid when moving to the ground having water stains; moreover, by means of the adjustment mechanisms (4), the first rollers (45) and the anti-skid wheels (44) can be switched at any time, so as to adapt to more environments in actual use.
