Problems solved by technology

However, most electric walking wheelchairs do not have the function of assisting sitting up, which makes it difficult for the elderly to get up and sit up when they want to walk independently from the wheelchair.
[0003] At present, the relevant patents at home and abroad mainly include a utility model named "Electric Wheelchair with Liftable Seat" (patent application number 03246351.0). In the process of sitting, the center of gravity of the human body is also constantly changing, and the center of gravity of the seat in this patent mainly changes in the vertical direction, and there is no movement in the horizontal direction. Therefore, this patent cannot be used according to the center of gravity of the human body. Patient reaches standing position
[0004] Moreover, when this patent is in use, the lifting mechanism drives the seat to move upwards, and the human body also moves upwards accordingly. If the user does not stretch out the feet in time to touch the ground, there will be problems such as the user's feet being separated from the ground. The difficulty caused by the user standing

Embodiment 1

[0033] The vertical standing mechanism 6 is an electric push rod 61 . Horizontal sit-up mechanism 7 comprises power plate 71 and the transverse slide rail 72 that is arranged on the power plate 71, and the base 5 is provided with the first slide block 73 that can move along transverse slide rail 72, and horizontal rise mechanism 7 also comprises drive base 5. The driving steel rope 74 that moves along the transverse slide rail 72. One end of the driving steel rope 74 is connected with the bottom of the car body 1, and the other end is connected with the first slider 73. At least two driving steel ropes are arranged on the power plate 71. The pulley 75 that the rope is wound, the winding mode is as image 3 , Figure 4 As shown, since one end of the driving steel rope 74 is connected to the first slider, and the other end is fixed to the car body, since the driving steel rope has an inelastic characteristic, the driving steel rope is vertically aligned during the movement of t...

Embodiment 2

[0040] The rest are the same as in Embodiment 1, the difference is that the vertical drive mechanism can also be a vertical cylinder or a motor and a screw drive, etc., the displacement of the base can be adjusted more accurately through the drive of the motor screw, and the specific method will not be described. limit.

Embodiment 3

[0042] The rest are the same as in Embodiment 1, the difference is that the horizontal lifting mechanism includes a power plate and a horizontal cylinder arranged on the power plate, and the base is fixedly arranged on the front end of the horizontal cylinder, and the base is moved horizontally by the promotion of the horizontal cylinder. There is no need to use components such as driving steel ropes and reset steel ropes. The usage of components is reduced, and the structure of the device is simplified. In addition to the horizontal cylinder, motor drive and other methods can also be used at this place, and there is no specific limitation.

Abstract

The invention discloses a multi-functional standing and sitting device for a walker wheelchair. A vertical standing and sitting mechanism and a transverse standing and sitting mechanism are arranged on an electric wheelchair, and the vertical standing and sitting mechanism is used for adjusting the lifting of a seat; the transverse standing and sitting mechanism is used for adjusting the horizontal movement of the seat, and the vertical standing and sitting mechanism and the transverse standing and sitting mechanism synchronously operate; and when the vertical standing and sitting mechanism drives the seat to lift, the transverse standing and sitting mechanism synchronously drives the seat to move forwards, so that the center of gravity of the human body is continuously changed so as to gradually help a user to stand up, and vice versa, the device helps the user to stand up and sit for exercise, and the standing and sitting difficulty of the user is reduced, so that the electric wheelchair is more humanized.

Description

technical field [0001] The invention belongs to the technical field of electric wheelchairs, in particular to a multifunctional walking aid wheelchair sitting device. Background technique [0002] With the aging of China's population, there are more and more elderly people with limited mobility. Most elderly people have not completely lost their walking ability and can walk for a short time, but they have great difficulty in standing up. At present, the development of electric wheelchairs has been relatively mature, and the elderly can use wheelchairs instead of feet to achieve the purpose of walking. However, most electric walking wheelchairs do not have the function of assisting sitting up, which makes it difficult for the elderly to get up and sit up when they want to walk independently from the wheelchair. [0003] At present, the relevant patents at home and abroad mainly include a utility model named "Electric Wheelchair with Liftable Seat" (patent application number...
