Stair climbing mechanism driven by motor

Abstract

The invention discloses a stair climbing mechanism driven by a motor. The stair climbing mechanism comprises a beam, wherein two wheels are separately arranged at two ends of the beam; the motor is fixedly arranged at one side of the beam; the two ends of the motor are separately and fixedly connected with the beam through fixed frames; an output shaft of the motor is connected with a crank and rocker mechanism, a motor shaft rotates to drive the crank and rocker mechanism to move, and lifting wheels are supported to go upstairs and downstairs. According to the stair climbing mechanism disclosed by the invention, the structure is light, and the labor intensity can be effectively reduced; a mechanical structure and electric control are combined, so that the operating space of equipment is large; the stair climbing mechanism is driven by the motor, so that the stair climbing mechanism is steady in operation, high in safety and high in stability in the use process, and high in stair climbing efficiency. The stair climbing mechanism adopts a modularization design, is small in size, convenient to carry, simple to mount and low in price, and has high practicality.

Description

【Technical field】 [0001] The invention belongs to the field of power-assisted machinery, and in particular relates to a motor-driven stair climbing mechanism. 【Background technique】 [0002] Present stair-climbing mechanism mostly is star-wheel type stair-climbing mechanism, crawler-type stair-climbing mechanism. The principle of crawler-type stair climbing machine is simple, and the technology is relatively mature, but its weight is heavy and its movement is not flexible enough. When climbing stairs, it will cause huge pressure on the edge of the stairs, which will damage the stairs to a certain extent. It is inconvenient to turn, the stability of the star wheel stair climbing mechanism is not high when going up and down the stairs, the center of gravity fluctuates greatly, and the star wheel stair climbing mechanism is large in size, it is difficult to use it on ordinary residential stairs, and domestically produced stair climbing machines exist How to improve the climbin...

Problems solved by technology

The principle of crawler-type stair climbing machine is simple, and the technology is relatively mature, but its weight is heavy and its movement is not flexible enough. When climbing stairs, it will cause huge pressure on the edge of the stairs, which will damage the stairs to a certain extent. It is inconvenient to turn, the stability of the star wheel stair climbing mechanism is not high when going up and down the stairs, the center of gravity fluctuates greatly, and the star wheel stair climbing mechanism is large in size, it is difficult to use it on ordinary residential stairs, and domestically produced stair climbing machines exist The overall weight is high, the efficiency of climbing stairs is low, it is inconvenient to carry, and the price is expensive. How to improve the climbing efficiency and portability has become a difficult problem in the field of stair climbing trucks
