Problems solved by technology

But in use because the upper body of the user is fixed on the backrest, the upper body is still in a vertical state due to the limitation of the seat in the process of standing up, which does not conform to the natural trajectory of the human body's standing up movement. The user mainly relies on the seat to passively Standing up hard, it is difficult to achieve the effect of exercise

Embodiment 1

[0044] figure 1 It is a structural schematic diagram of the rehabilitation wheelchair of the present invention in a folded state, figure 2 It is a structural schematic diagram of the rehabilitation wheelchair of the present invention when it is in an extended state, image 3It is the rear view of the rehabilitation wheelchair of the present invention. As shown in the figure, the rehabilitation wheelchair of the present invention includes: driving wheel 1, vehicle frame 2, driven wheel 3, pedal 4, pedal connector 5, seat cushion 6, armrest 7, clutch button 8, backrest 9, card Buckle 10, protective casing 11, handle 12, six-bar mechanism 13, support frame 14, baffle plate 15, motor 16, manual wheel 17, handbrake 18, battery 19 and clutch 20. Wherein the driving wheel 1 is used to drive the entire rehabilitation wheelchair to move, and the driven wheel 3 is a direction control wheel. The pedal connector 5 is an elastic connector. The handle 12 facilitates controlling the mov...

Embodiment 2

[0059] This embodiment is further limited on the basis of Embodiment 1.

[0060] The lifting device has a backrest and a six-bar mechanism located in the middle of the support frame on the back of the rehabilitation wheelchair. The fifth rod 13e in the six-bar mechanism 13 is a pulley fixed on the fourth rod 13d, and one end of the sixth rod 13f is rotatably fixed on the edge of the pulley. The position where the center of the pulley is fixed to the sixth bar 13f is the length of the fifth bar 13e. The motor 16 controls the motion of other four rods by controlling the rotation of the pulley.

[0061] The rehabilitation wheelchair of the present invention is also equipped with an intelligent terminal device as a control terminal, and the intelligent terminal device is connected with the rehabilitation wheelchair through wired or wireless means to control the motion state of the lifting device and the rehabilitation wheelchair. The intelligent terminal device may be a controll...

Embodiment 3

[0066] This embodiment is further limited on the basis of Embodiment 2.

[0067] Such as Figure 5 As shown, the rehabilitation wheelchair includes: driving wheel 1, frame 2, driven wheel 3, pedal 4, pedal connector 5, seat cushion 6, armrest 7, clutch button 8, backrest 9, buckle 10, protective shell 11. Handle 12, six-bar mechanism 13, support frame 14, baffle plate 15, motor 16, hand wheel 17, hand brake 18, battery 19, clutch 20, transmission chain 21, terminal support frame 22 and sensor assembly. The terminal support frame 22 is used to place the intelligent terminal equipment or used as a shelf, and the transmission chain 21 is used to transmit the driving force of the motor 16 to the six-bar mechanism 13 .

[0068] The sensor assembly includes: a foot sensor 4a, a cushion sensor 6a, an armrest sensor 7a and a back sensor 9a, which are respectively placed in the footrest 4, the cushion 6, the armrest 7 and the backrest 9 to sense the physiological state of the user. T...

Abstract

The invention provides a rehabilitation wheelchair. The rehabilitation wheelchair is provided with a standing assisting device which is provided with at least one single-freedom-degree six-rod mechanism, and the single-freedom-degree six-rod mechanism is used for controlling a backrest connected to the six-rod mechanism to reciprocate according to an assigned track so that assistance force helping a user to stand up and sit down can be applied to the user. Due to the fact that the standing assisting device is adopted for the rehabilitation wheelchair, a user weak in waist strength can be helped to stand up or sit down, meanwhile, standing and sitting training can be assisted, and therefore waist rehabilitation training can be performed. The single-freedom-degree six-rod mechanism is adopted, the mechanical structure is simplified, and cost is saved. Besides, by simulating the human body motion track, the wheelchair is more humanized and is convenient to use.

Description

technical field [0001] The invention relates to the field of rehabilitation wheelchairs, in particular to the field of rehabilitation wheelchairs. Background technique [0002] At present, the development of electric walking rehabilitation wheelchairs has been relatively mature. People hope to give more functions to the rehabilitation wheelchair for easy use. For elderly people with limited mobility or patients with damaged waists who need exercise, sitting in rehabilitation wheelchairs for a long time is not conducive to health, but due to their poor physical fitness, it is more difficult to sit up. At present, most walking aid rehabilitation wheelchairs do not have the function of assisting sitting up. Especially for the patient who needs to carry out waist rehabilitation training by sit-up training, there is no corresponding auxiliary exercise rehabilitation wheelchair. [0003] Chinese patent CN101828995A discloses a kind of electric mobility-assisted rehabilitation w...
