Embodiment 1

[0030] Embodiment 1: as Figure 1~Figure 16 As shown, the independent self-service barrier-free wheelchair is composed of a stair climbing mechanism, a level ground movement mechanism, a power mechanism 2, a seat mechanism 1 and a frame 3, the seat mechanism 1 is fixed in the middle of the upper part of the frame 3, and the stair climbing mechanism is fixed At the bottom of the frame 3 , the ground motion mechanism is fixed at the front and rear ends of the frame 3 , and the power mechanism 2 is fixed at the two outer sides of the frame 3 top.

[0031]The stair climbing mechanism consists of the body 12 that is upturned from the front and 12 shock-absorbing flexible power wheel sets (6 groups on each side) that are arranged on both sides of its lower end, the sprocket wheel 20 that is installed on the small wheel shaft 23 of the power wheel set, and The chain mechanism 11 passing through the sprockets 20 of each wheel group mechanism is composed of a body 12 fixed on the frame...

Embodiment 2

[0038] Embodiment 2: as Figure 1~Figure 13 As shown, the structure of the wheelchair is the same as that of Embodiment 1, and there are 10 sets of shock-absorbing flexible power wheel sets in total, 5 sets on each side. When two steamboats 10 are connected with frame 3 by body connecting piece 7, be 15 ° with vertical direction and install inclined forward, guarantee the realization of whole mechanism function.

Embodiment 3

[0039] Embodiment 3: as Figure 1~Figure 13 As shown, the structure of the wheelchair is the same as that of Embodiment 1, and there are 14 sets of shock-absorbing flexible power wheel sets in total, 7 sets on each side. When two steamboats 10 are connected with frame 3 by body connecting piece 7, be 30 with vertical direction 0 The installation is tilted forward to ensure the realization of the function of the whole mechanism.

Abstract

The invention discloses an independent self-help barrier-free wheelchair totally manually operated and used for independently, conveniently and stably climbing stairs, and belongs to the technical field of wheelchairs. The wheelchair consists of a stair climbing mechanism, flat ground movement mechanisms, power mechanisms, a seat mechanism and a frame; the seat mechanism is fixed at the upper middle part of the frame; the stair climbing mechanism is fixed at the lower part of the frame; the flat ground movement mechanisms are fixed at the front end and the rear end of the frame; and the power mechanisms are fixed on two outer sides of the upper part of the frame. The stair climbing mechanism consists of a body with upwards warped front, a plurality of damping flexible power wheel sets positioned on two sides of the lower end of the body respectively, chain wheels arranged on a small wheel axle of the power wheel sets, and a chain mechanism passing through the chain wheels of the wheelset mechanisms; and the body is fixed on the frame. The wheelchair has the advantage that a user can walk freely on the flat ground, stairs and slopes without the assistance of others. Meanwhile, due to the pure mechanical structure of the wheelchair, the wheelchair has low cost and is suitable for medium and low-end markets.

Description

Technical field [0001] The patent of the present invention is a fully manual and purely mechanical barrier-free wheelchair, which belongs to a barrier-free wheelchair that can be used by disabled people on flat ground and stairs. Background technique [0002] At present, most of the wheelchairs used by the disabled on the market are ordinary wheelchairs that can only walk on flat ground. Some stair climbing wheelchairs at home and abroad have expensive electrical components, which makes the price of the wheelchair very high, and is not suitable for the majority of low-income leg disabled people. . Common types of low-cost wheelchairs are tracked and wheeled. Crawler wheelchairs only contact the sharp corners of the stairs, and their reliability is not high. Wheeled wheelchairs are more bumpy in motion and less comfortable. Contents of the invention [0003] In order to overcome the defects of the existing wheelchairs, such as unstable stair climbing, high price, low rel...
