Embodiment Construction

[0029] For ease of understanding, the spatial orientation is stipulated as follows: the direction of climbing stairs is "front", and the position of the rear wheels is "rear". Correspondingly, facing the direction of climbing stairs, it can be divided into "left", "right", The orientations of "up" and "down" are vertical along the front-back direction, and horizontal along the left-right direction. The following descriptions all follow the above principles.

[0030] The concrete structure of the present invention is as follows: from top to bottom successively is workbench part, center of gravity adjusting device, front and rear and up and down telescopic device and driving traveling device.

[0031] Such as figure 1 As shown, the workbench components are composed of a workbench 1, a cover plate 2, a mode button 3, a ratchet lock 4, a T-shaped handle 5 and a fixed support 6. The workbench 1 is a cuboid platform structure, parallel to the horizontal plane in the original state,...

Abstract

The invention discloses a three-foot stair climbing device for helping the elder and the disabled in a corridor and an implementing method of the three-foot stair climbing device. A gravity adjusting device, a battery module and a control system are arranged in a working table, and according to the gravity adjusting device, a stepping motor is adopted to drive a lead screw to adjust the front-back position, relative to the working table, of a mass block, so that the stability of the gravity of the device in the stair climbing process is ensured; according to a front-back and up-down telescopic device, three main electric push rods vertically distributed are adopted so that three feet can ascend or descend, and two auxiliary electric push rods horizontally arranged are adopted so that the three feet can move horizontally in the stair climbing process; according to a driving traveling device, a rear wheel hub motor is adopted for driving, front wheels and middle wheels are steering wheels, a ratchet mechanism capable of being opened or closed is arranged on each wheel, on one hand, the safety of the stair climbing process is ensured, on the other hand, ratchet reverse locking is used for cooperating with the auxiliary electric push rods to achieve different moving combinations of the three feet, the three-foot stair climbing device can assist in stair climbing and can be used for riding instead of walking on the flat ground, the posture is horizontal in the stair climbing process, the gravity of the device is adjustable, three-foot stair climbing device is stable and reliable, and the wheels have the ratchet reverse locking function and are good in safety.

Description

technical field [0001] The invention relates to the technical field of transportation for the elderly and the disabled between corridors, in particular to a stair-climbing device that can not only walk on flat ground, but also be suitable for occasions without elevators, and assist people to go up and down stairs or carry heavy objects. Background technique [0002] Newly built high-rise or small high-rise residential buildings are equipped with elevators to facilitate people going up and down stairs, but elevators are far from being popular below small high-rise buildings or in many old residential buildings; at the same time, with the acceleration of population aging, the elderly are increasingly For the most part, they need to go up and down stairs frequently when shopping for vegetables and taking a walk after meals in their daily life, and sometimes even need to carry some heavy objects, but their old physical conditions have brought great troubles and even hidden danger...
