Problems solved by technology

Among the currently widely used electric wheelchairs, the use of most electric wheelchairs requires users to get on and off the wheelchair independently, and this process is very limited for some patients with severe illnesses and groups with mobility impairments; when users want to get out of the wheelchair When transferring to a bed for rest, the movement can only be realized through the assistance of external force; at the same time, for the road surface with obstacles, ordinary electric wheelchairs need to apply a lot of force and generate a lot of impact, which will have a great impact on the patient's body. cause a lot of damage

Embodiment Construction

[0021] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0022] combine Figure 1~1 2. An electric wheelchair that can assist patients in getting on and off the bed and can complete the functions of backrest adjustment and obstacle surmounting, including wheelchair frame 1, a retractable armrest mechanism, a seat lateral movement mechanism, a backrest adjustment mechanism and an obstacle surmounting mechanism.

[0023] The handrail mechanism that can complete the retractable function includes a handrail 6, a first connecting rod 8, a right-angled rod 7, and a second connecting rod 9. What is adopted between the handrail 6 and the first connecting rod 8 is a pin 11 to connect, and the first connecting rod 8 The bottom is pinned to the hole on the boss 12 of the wheelchair frame 1. The boss 12 and the wheelchair steel frame 1 are welded. When the armrest 6 is put down, only the right angle b...

Abstract

The invention provides an electric wheelchair having functions of assisting going to and going out of beds and crossing over obstacles. The wheelchair comprises a wheelchair main body, a seat, a seatmoving mechanism, a backrest adjusting mechanism, foldable armrest mechanisms and an obstacle-crossing mechanism. The foldable armrest mechanisms comprise armrests, connecting rods and right-angle rods. The seat moving mechanism comprises the seat, an electric motor, belt wheels, a synchronous belt, a sliding block connecting plate, a crank, connecting rods, a sliding block and a sliding rail. Thebackrest adjusting mechanism comprises an electric motor, belt wheels, a synchronous belt, straight toothed spur gears and a backrest. The obstacle-crossing mechanism comprises two swing rods, smallwheels, an electric motor, a speed reducer and bevel gears. Meanwhile, the backrest adjusting mechanism and the obstacle-crossing mechanism are subjected to time-sharing driving by virtue of the samemotor and an electromagnetic clutch. The electric wheelchair provided by the invention, which has the function of crossing over the obstacles, can cross over obstacles which are 20cm high; the electric wheelchair provided by the invention is convenient for a user to operate and control; patient's motion freedom is improved, patient's motion intensity is reduced and workload of family members is reduced.

Description

technical field [0001] The invention relates to a wheelchair, in particular to an electric wheelchair with the functions of assisting getting on and off the bed and overcoming obstacles. Background technique [0002] As a new type of means of transportation, electric wheelchairs are mainly suitable for special groups with limited mobility, such as the disabled, medical rehabilitation patients, and the elderly and infirm. Compared with traditional manual wheelchairs, electric wheelchairs are more convenient and easy to operate, so they are more widely used. Among the currently widely used electric wheelchairs, the use of most electric wheelchairs requires users to get on and off the wheelchair independently, and this process is very limited for some patients with severe illnesses and groups with mobility impairments; when users want to get out of the wheelchair When transferring to a bed for rest, the movement can only be realized through the assistance of external force; at...
