Self-control wheel-track automatic-switching stair-climbing machine

Abstract

The invention discloses a self-control wheel-track automatic-switching stair-climbing machine. The self-control wheel-track automatic-switching stair-climbing machine is characterized in that: a wheel-track switching mechanism is arranged in a way that: front and rear wheels are assembled on wheel shafts on the two sides of each of a front wheel shaft bracket and a rear wheel shaft bracket; the middle parts of the front and rear wheel shaft brackets are provided with lifting drive shafts connected into a whole; the lifting drive shafts and the wheel shafts on the two sides form eccentric structures; the two sides of each of the front and rear wheel shaft brackets are fixed with a push shank respectively; connecting rods are hinged between the front and rear push shanks on the two sides; the lifting drive shaft of the rear wheel shaft bracket is fixed with a rocking handle; a vehicle frame is fixedly connected with a support arm; an electric push rod of an electric push rod component is hinged with the rocking handle, while a push rod seat is hinged with the support arm; and a steering mechanism is arranged in a way that: the vehicle frame is provided with a driven steering wheel lifting mechanism frame which is hinged with the electric push rod seat; a driven steering wheel supporting arm is hinged with the electric push rod of an electric push rod component; and the middle part of the driven steering wheel supporting arm is connected to the driven steering wheel lifting mechanism frame by a pin shaft, while an end part is connected with a driven steering wheel. The self-control wheel-track automatic-switching stair-climbing machine has the advantages of traveling on a flat ground, climbing stairs, realizing free switching according to needs and realizing a zero-turning radius, along with safety and reliability in use.

Description

technical field [0001] The invention relates to an automatic device capable of integrating the functions of walking on flat ground and climbing stairs. Walking on flat ground and climbing stairs can be automatically switched, and the angle of climbing stairs is 35 degrees. Background technique [0002] At present, there are several forms of devices for climbing stairs, such as star wheel type and crawler type, and there are several types of devices for walking on flat ground, such as four-wheel and three-wheel, etc., but no combination of walking on flat ground and climbing stairs has been found yet. Mechanical device, which brings great inconvenience to the demander. When the two functions of the wheel and the shoes are combined, the strengths of both can be fully brought into play, and it has the dual functions of walking on level ground and climbing stairs. Contents of the invention [0003] The purpose of the present invention is to overcome the shortcomings of being...

AI Technical Summary

Problems solved by technology

[0003] The object of the present invention is to provide a self-controlled wheel-track automatic conversion stair climbing machine in order to overcome the shortcomings of being unable to climb stairs when walking on flat ground, and unable to walk on flat ground when climbing stairs. It can be freely converted according to the needs to achieve zero turning radius, safe and reliable to use
