A robotic adjustable three-blade wheel for climbing stairs

Abstract

The invention belongs to the technical field of adjustable three-blade wheels for robots, and particularly relates to an adjustable three-blade wheel for a stairs climbing robot. The adjustable three-blade wheel comprises a driving motor, climbing blades, support toothed bars, a mounting shell and a servo motor. The adjustable three-blade wheel has the advantages that the climbing blades of the adjustable three-blade wheel need to be adjusted to adapt to stairs required to be climbed when the adjustable three-blade wheel is about to be used, the servo motor can be driven to work at the moment,a driving mounting disc can be driven by the servo motor via a servo motor rotary shaft to rotate, a driving rotary shaft can be driven under the rotation actions of the driving mounting disc to rotate, and the support toothed bars and the three corresponding climbing blades can be adjusted to adapt to the stairs under the rotation actions of the driving rotary shaft; the driving motor can be driven to work after the support toothed bars and the three corresponding climbing blades are completely adjusted, accordingly, an output shaft can be driven by the driving motor to rotate, the mountingshell can be driven by the output shaft to rotate, the three climbing blades can be driven by the mounting shell to rotate around the axis of the mounting shell, and the robot can be driven to go downstairs under the rotation actions of the three climbing blades.

Description

technical field [0001] The invention belongs to the technical field of robot adjustable three-impellers, in particular to a robot adjustable three-impeller for climbing stairs. Background technique [0002] There are a large number of old, weak, sick, and disabled groups in the country. It is inconvenient for outdoor and indoor climbing stairs, and the demand for means of transportation is increasing. In order to solve the practical problems of these special groups, various forms of variable wheel stair-climbing wheelchair robots have been adopted at home and abroad, including manual and electric stair-climbing wheelchairs, crawler type, wheel group type, track type, etc. However, the current variable wheel stair-climbing wheelchair has some defects, such as the inflexible movement of the crawler-type stair-climbing wheelchair, large size, heavy weight, great damage to the building body, and is not suitable for ordinary residents to walk in corridors; while the wheel set str...

Problems solved by technology

However, the current variable wheel stair-climbing wheelchair has some defects, such as the inflexible movement of the crawler-type stair-climbing wheelchair, large size, heavy weight, great damage to the building body, and is not suitable for ordinary residents to walk in corridors; while the wheel set structure is complex, The price is high and the stability is poor; the track type needs a special track, which is not suitable for ordinary consumers; some wheelchairs rely on star wheel climbing stairs, which require people to push and pull, poor stability and troublesome operation; some have many problems with the balance design of the chair when the wheelchair goes up and down stairs Unrealistic defects, and using the motor-driven lifting mechanism to adjust the balance is feasible, but there are defects in the balance adjustment response and inflexible operation; so design a balance adjustment response sensitive, flexible operation, simple structure, cost-effective High stair-climbing robot walking platform is very necessary
