Embodiment Construction

[0008] The present invention will be described in detail below in conjunction with the accompanying drawings and embodiments. Refer to attached picture, figure 1 The driving parts of the wheelchair traveling mechanism that automatically adapts to the road conditions shown are composed of a load wheel 1, a rubber track 2, a front drive wheel 3, a rubber track tensioning device 4, a guide wheel 10, a rear drive wheel 12, and a stepping drive motor 13; The adjusting part is made up of parallel hydraulic cylinder 5, upper connecting rod 6, parallel oil pipe 7, balance adjustment hydraulic cylinder 9, lower connecting rod 11, seat position sensor 14, seat support frame 15, seat suspension rod 16.

[0009] When the wheelchair moves up the stairs, the suspension seat 8 is always kept in a vertical position by gravity, so that the seat suspension rod 16 and the seat support frame 15 are staggered by an angular displacement, and the seat position sensor 14 obtains the data and then adj...

Abstract

The invention discloses a wheel chair travelling mechanism capable of automatically adapting to the road condition, which is used for patients with physical disability or pathological changes and old people with mobility difficulty to walk up or down the stairs and ride instead of walk in daily travel, and belongs to the field of medical apparatus. The key components related with the invention are composed of a track, a driving system, seven load bearing hydraulic cylinders communicated with each other, a balance adjusting hydraulic cylinder, hung seat position sensors and the like. The seven load bearing hydraulic cylinders, an upper connecting rod and a lower connecting rod form a plane movement mechanism. When a wheel chair goes uphill or downhill and the wheel chair is inclined, a hung seat is always vertical downwards due to the action of gravity, the sensors are used for measuring the relative displacement between seat hanging bars and a support frame, and the balance adjusting hydraulic cylinder is driven to keep the seven load bearing hydraulic cylinders always vertical downwards, so as to maintain the balance of the system.

Description

technical field [0001] The invention provides a wheelchair tool for transporting patients with handicapped limbs to go up and down stairs. Specifically, the adaptation and balance to the road surface is realized through the equal pressure principle of parallel hydraulic cylinders and a planar movement mechanism, and belongs to the field of medical equipment. Background technique [0002] With the development of urbanization, a large number of multi-storey buildings have increasingly become people's daily residences, causing many patients with physical disabilities and elderly people with limited mobility to have difficulty in daily travel and unable to take care of themselves; at the same time, leisure in urban parks In recreational activities, groups with physical disabilities also need a reliable means of transportation. In recent years, some designers at home and abroad have also developed wheelchair traveling mechanisms with the function of assisting up and down stairs, ...
