Electric wheelchair driven by one foot

Abstract

The invention relates to a novel electric wheelchair, in particular to a handicapped electric wheelchair on which a person sits and can drive the handicapped to move forward by using a supporting leg. In the disabled people, both hands are disabled, and only one foot is good, so that the disabled people are inconvenient to move, and particularly, the latter is almost unable to go out. The invention may provide them, especially the latter, with a vehicle. The electric wheelchair is convenient to operate, after a person sits on the electric wheelchair, the person only needs to step on the double pedals under the feet, and the wheelchair can move forwards, retreat, bend leftwards, bend rightwards and brake by stepping on the pedals forwards, backwards, obliquely leftwards and obliquely rightwards, so that the electric wheelchair is simple to operate and can be learned at a time. After being stored and folded, the device is small in size and easy to store. And the pull rod can be pulled out to be easily dragged. And a user can go out to travel as long as accompanied by a healthy person.

Description

Technical Field

[0001] The invention relates to an electric wheelchair, in particular to an electric wheelchair which can be driven by one foot. Background Art

[0002] Currently known electric wheelchairs are all driven by hand, but among the disabled people, some have both hands disabled, and a few have one foot disabled, so they have difficulty in moving, especially the latter, who have basically lost the ability to walk or go out. Summary of the invention

[0003] In order to solve the above problems, the present invention provides an electric wheelchair which can be driven by one foot. After sitting on the wheelchair, the wheelchair can be driven forward, backward, left, right and braked by one foot, and the control is simple.

[0004] The technical solution adopted by the present invention to solve the technical problem is: a balance car is used as the front wheel, two universal wheels are used as the rear wheels, a carriage-type tray is placed on the tray, a seat is placed on the tray, and at the same time, a strip pedal is installed in the middle of the two pedals of the balance car, and the rear half of the two strip pedals is bolted to the rear half of the balance car pedal, the front half of the pedal is tilted, and the heel is turned up to limit the position, and the total width of the two strip pedals is consistent with the width of the shoe. When pressing forward, backward, left, and right, the wheelchair

[0005] Since electric wheelchairs all have the functions of storage, folding, storage and transportation, the specific structure of the one-legged electric wheelchair is as follows: a triangular channel steel is placed on each side of the balance vehicle pedal, a steel pipe is bent into a U shape, and both sides are embedded in the channel steel. The bottom of the steel pipe keeps a small distance from the bottom of the channel steel, and can be slightly rotated after the axle pin is put on. The two rear sections of the U-shaped steel pipe are inserted under the tray. On both sides, two sliding pipe clamps are arranged in a channel, which can be pushed in or pulled out and positioned by the card pin on the front of the tray; a universal wheel is installed under the support plates welded on both sides of the rear of the tray, and they constitute the walking part of the one-legged electric wheelchair.

[0006] A seat is installed on the tray, and a lifting mechanism is added between the seat and the tray. Two frames are bent into a U shape, and the sides are crossed into an X shape, and the middle is in contact and connected by a thread. The horizontal pipe behind the two frames is pressed on the tray and under the seat bottom plate by two sliding pipe hoops, respectively. The four ends extending forward are riveted with a thread respectively. At the lower and upper points of the four ends, two sections of slide rails are welded on the tray, and two sections of slide rails are welded under the seat bottom plate. The two thread pins at the lower and upper ends are respectively inserted into their respective slide rails and locked with an opening pin, and the seat can be raised and lowered. For positioning, a groove is opened at the tail of the two lower slide rails 11, and the groove is round in front and inclined upward in the back. When the seat is lifted, the two lower thread pins move backward on the slide rail. When they move to the groove, the thread pins fall down and hook the arc, so that the person sitting is stable. When it is to be put down, the seat is first lifted up, and the thread pin is pushed up. At this time, the seat is pressed down quickly, and the thread pin has no time to fall, and it passes through the groove and moves forward to flatten the seat.

[0007] When storing, push the balance bike under the tray, insert the latch, lay the seat flat and then fold the backrest flat, the volume becomes smaller and easier to store. If you need to tow it, pull out the rear pull rod and you can tow it.

[0008] The beneficial effects of the present invention are: providing a one-legged electric wheelchair for disabled persons with both hands injured, especially disabled persons with only one leg left, which is simple and convenient to operate and can be compacted after being stored. The disabled persons can go out or travel as long as they are accompanied by a healthy person, thus showing love to such disabled persons. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0015] exist Figure 1 In the figure, the balancing car 1 is connected to the tray 4 on the U-shaped steel frame 2 through the pipe clamp 5 embedded with the triangular channel steels 3 on both sides thereof, and then the two universal wheels 6 under the supporting plates 18 on both sides of the rear of the tray 4 constitute a walking mechanism.

[0016] On the tray 4, 7 is a cushion and 8 is a backrest. The two of them form a folding seat through a rotating frame 17, which is supported by an X-shaped lifter below. 9 and 12 are crossed upper and lower U-shaped frames. The transverse tube of the upper U-shaped frame 9 is pressed on the tray by two pipe hoops 10, and the transverse tube of the lower U-shaped frame is pressed under the bottom plate of the cushion 7 by two pipe hoops 13. The middle part where they meet is connected by a pin. At the same time, in front of the tray and the bottom plate of the cushion, a section of lower slide rail 11 and upper slide rail 14 are welded on both sides. The pins on the four ends of the front ends of the two U-shaped frames are respectively inserted into their respective slide rails and locked with an open pin. In order to control the height of the seat, a groove is opened at the tail of each of the two lower slide rails 11. The groove is round in front and inclined at the back. When the two lower pins of the lifting seat move backward on the slide rail, when they move to the groove, the pins fall down and hook the arc. At this time, the backrest 8 is lifted up and stands obliquely on the rotating frame 17, blocked by the back of the rotating frame, and the person sitting can operate it.

[0017] At this time, the wheelchair can move forward, backward, bend left or right by stepping on the two strip pedals 15 and 16 with one foot. A light pressure will make it slow, while a heavy pressure will make it fast. When braking is needed, just step on the pedal in the opposite direction.

[0018] When storing, 1. Lift the two latches 19 in front of the tray, push the balance car under the tray, and put down the latches 19. 2. Flip down the seat back, lift the seat lightly, the hook strip will pop up, and then press the seat lightly, the hook groove will step over the hook strip until the seat is laid flat.

[0019] If the vehicle needs to be towed, the pull rod 20 at the rear lower portion can be pulled out to tow the vehicle.

Claims

1. A one-legged electric wheelchair, characterized by: A balance bike is used as the front wheel and two universal wheels are used as the rear wheels. A carriage-type tray is placed on the tray, and a liftable and foldable seat is placed on the tray. At the same time, a strip pedal is installed in the middle of the two foot pedals of the balance bike, and the total width is consistent with the shoe width. The rear half of the two strip pedals is installed on the rear of the original pedals with bolts, and the front half is tilted up, and the heel is folded up to limit the position. When a person sits on the seat, stretches out his feet, steps on the two strip pedals, presses forward, backward, left, and right, the wheelchair can move forward, backward, turn left, and turn right. When braking, the person only needs to step on the pedal in the opposite direction to stop the car. The operation is simple.
