Electric stair climber

Abstract

The invention discloses an electric stair climber. The electric stair climber comprises a bracket, a seat, an operating rod, a bearing bracket assembly, two big wheels, and a stair climbing assembly, wherein the bracket comprises a left slide rail, a right slide rail, and a connection bottom plate connecting the left slide rail and the right slide rail; through pulleys which are respectively arranged on both sides of the bearing bracket assembly, the bearing bracket assembly is mounted on slide grooves which are respectively formed in the left slide rail and the right slide rail; the seat is mounted on the bearing bracket assembly; each big wheel is hinged to one end of each slide rail; the stair climbing assembly comprises a motor, a decelerator and stair climbing wheels, wherein the input shaft of the decelerator is connected with the output shaft of the motor; each stair climbing wheel is mounted at each of both ends of the output shaft of the decelerator; each stair climbing wheel comprises a wheel body, stair climbing arms, stair climbing cranks and rolling wheels; the wheel bodies are mounted on the output shaft of the decelerator; at least two stair climbing arms are uniformly distributed on each wheel body; each stair climbing crank is arranged on the outer lateral side of each stair climbing arm; each rolling wheel is mounted at the end of each stair climbing arm. According to the electric stair climber disclosed by the invention, the power consumption can be lowered, and the movement is stable; regardless of the angle formed between the electric stair climber and the ground level, the original relative state of a born object and the ground level is always maintained.

Description

technical field [0001] The invention is an electric stair climbing device, which belongs to the innovative technology of the electric stair climbing device. Background technique [0002] The current electric stair climbing device mainly has the following two structures: 1) A plurality of straight rods based on the rotation center are evenly distributed radially, and a runner is installed at the end of each straight rod away from the rotation center, such as Figure 14 As shown in the figure, when these straight rod assemblies rotate around the center of rotation, due to the gap between the two adjacent rods, they can fit the shape of the stairs so that they can go up and down the steps, so as to achieve the purpose of ascending or descending the load on the stairs. 2) Tracked device, that is, a miniature tank. When the first structure works, after the small wheel is in contact with the ladder surface, the instantaneous center of the moving part falls on the rotation center o...
