Electric stair-climbing machine for carrying person

Abstract

The invention discloses an electric stair-climbing machine for carrying a person, pertaining to the field of assisted-living mechanical equipment. The electric manned stair-climbing machine comprises an armrest, a frame, a battery, a motor and a speed reducer, wheels, a seat and a stair-climbing actuating mechanism. The stair-climbing actuating mechanism is composed of stair-climbing wheels and installing racks. When the machine goes upstairs, the motor rotates forwards to drive the installing racks to perform rotary motion clockwise such that the stair-climbing wheels stay on the upper stair. The installing racks continue to rotate in order to support the stair-climbing machine. After the stair-climbing machine is put on the upper stair, the installing racks continue to perform rotary motion in order to go upstairs. When the machine goes downstairs, the motor rotates reversely and the installing racks perform anticlockwise rotary motion such that the stair-climbing wheels are supported on the current stair. The installing racks continue to perform rotary motion so that the stair-climbing machine is placed on the later stair. The installing racks continue to perform rotary motion in order to go downstairs.

Description

technical field [0001] The invention relates to an electric manned stair climbing machine, which belongs to the field of mechanical equipment for assisting living. Background technique [0002] For the current electric manned stair climbing machines, there are star wheel type, crawler type, self-driving type, etc. The star wheel type manned stair climbing machine has fixed star wheel track and depth, but the height and width of the stairs are different. , in the process of climbing stairs, there will be misalignment and slippage, which has certain potential safety hazards; when the crawler-type manned stair climbing machine leaves the previous step or goes to the next step, it will tilt forward and backward due to the deviation of the center of gravity. The stair climbing machine adopts crawler transmission, which has a large friction with the corridor, so the wear and tear on the crawler belt is large and the maintenance cost is high in the later period; the self-driving ma...

Problems solved by technology

[0002] For the current electric manned stair climbing machines, there are star wheel type, crawler type, self-driving type, etc. The star wheel type manned stair climbing machine has fixed star wheel track and depth, but the height and width of the stairs are different. , in the process of climbing stairs, there will be misalignment and slippage, which has certain potential safety hazards; when the crawler-type manned stair climbing machine leaves the previous step or goes to the next step, it will tilt forward and backward due to the deviation of the center of gravity. The stair climbing machine adopts crawler transmission, which has a large friction force with the corridor, so the wear on the crawler belt is large and the maintenance cost is high in the later period; the self-driving manned stair climbing machine is not suitable for turning operation in the corridor due to its large size.
