[0030] See also Figure 1-6The utility model provides a technical solution: a wheelchair for assisting the disabled, comprising a base 1, a bottom plate 2, a seat cushion 3, a back plate 4, a rear wheel 5, a pedal 6, a front wheel 7, a support column 8, an armrest 9, a cushion block 10, a connecting rod 11, an electric push rod 12, a motor 13, a controller 14, a connecting plate 15, a support plate 16, a driven wheel 17, and a driving wheel 18.
[0031] This device has the effect of assisting people to stand up, specifically:
[0032] The base 1 is a hollow structure with an open side surface. A bottom plate 2 is fixedly installed on the top of the base 1, a seat cushion 3 is fixedly installed on the upper surface of the bottom plate 2, and a back plate 4 is fixedly installed on the upper surface of the seat cushion 3. A rear wheel 5 is arranged on one side of the base 1. Two rear wheels 5 are symmetrically arranged. The two rear wheels 5 are installed on the same rotating shaft surface. The rotating shafts of the rear wheels 5 are rotatably installed on the side surface of the base 1 through a bracket. A pedal 6 is fixedly installed on the lower surface of the base 1. The pedal 6 is provided on one side of the pedal 6. The two front wheels 7 are installed on the same rotating shaft surface. The rotating shafts of the front wheels 7 are rotatably connected with the pedal 6 through a bracket. The surface of the bottom plate 2 is provided with an auxiliary standing structure. The body structure is provided with an armrest 9 that slides up and down to achieve the effect of assisting the disabled to stand up. The assisting standing structure includes a support column 8, which is fixedly installed on the upper surface of the bottom plate 2. The outer surface of the support column 8 is slidably connected with the armrest 9. The armrest 9 is arranged parallel to the upper surface of the bottom plate 2. A pad 10 is slidably installed on the outer surface of the armrest 9. The surface of the pad 10 is a flexible material. There are two support columns 8, two armrests 9 and two pads 10 symmetrically arranged respectively. The lower surfaces of the two armrests 9 are fixedly connected to the surface of the same connecting rod 11. An electric push rod 12 is fixedly installed on the upper surface of the bottom plate 2. The output end of the electric push rod 12 is fixedly connected to the lower surface of the connecting rod 11.
[0033] like Figure 1 , Figure 2 and Figure 4 As shown, when using the device, the user sits on the upper surface of the seat cushion 3 and leans his back against the surface of the backboard 4. At this time, the user's hands can be placed on the surface of the pad 10 on the outer surface of the armrests 9 on both sides. The surface of the pad 10 is made of flexible material, which can increase the comfort of the user, and the pad 10 is slidably connected to the armrests 9, so that the pad 10 can adapt to users of different body shapes. When the user needs to get up, the controller 14 on the surface of the armrest 9 is used to control the electric push rod 12, and the electric push rod 12 drives the connecting rod 11 to move upward, and the connecting rod 11 drives the armrests 9 on both sides to slide upward on the surface of the support column 8, giving the user's arms an upward thrust, thereby assisting the user to get up.
[0034] The device has the effect of assisting leg exercise, specifically:
[0035] A driving structure is arranged inside the base 1. The driving structure is provided with a motor 13 to control the movement of the wheelchair and drive the disabled person's legs to move through a driving wheel 18. The driving structure includes a motor 13. The motor 13 is fixedly installed inside the base 1 and is a bidirectional output structure. A transmission chain is arranged at the output end of the motor 13 to be transmission-connected with the outer surface of the rear wheel 5. The armrests 9 on both sides are respectively provided with a controller 14. The controller 14 is connected with the electric push rod 12 and the motor 13. A connecting plate 15 is rotatably arranged on the inner wall of the base 1. Two connecting plates 15 are symmetrically arranged. A supporting plate 16 is rotatably arranged between the two connecting plates 15. A driven wheel 17 is arranged on the outer surface of the rotating shaft of the connecting plate 15. The driven wheel 17 is a gear structure. A driving wheel 18 is meshed on one side of the driven wheel 17. The driving wheel 18 is a toothless structure and is connected to the output end of the motor 13. A V-shaped groove is arranged in an annular manner on the outer surface of the front wheel 7.
[0036] like Figure 1 , Figure 3 , Figure 5 and Figure 6 As shown, when the user uses the wheelchair to move, the controller 14 on the surface of the armrests 9 on both sides can be used to control the motor 13 to start. The controllers 14 on both sides can be used by left-handed or right-handed people. The user's legs can be placed on the surface of the fixed pedal 6, or on the surface of the support plate 16. When the legs are placed on the surface of the support plate 16, the motor 13 starts to drive the rear wheel 5 to rotate, thereby driving the wheelchair to move. At the same time, the start of the motor 13 will drive the driving wheel 18 to rotate, and the driving wheel 18 with a toothless structure will intermittently drive the driven wheel 17 to rotate. When the driven wheel 17 rotates, the driven wheel 17 drives the connecting plate 15 to rotate, and the connecting plate 15 drives the support plate 16 to move, thereby driving the legs on the upper surface of the support plate 16 to move. When the driven wheel 17 stops rotating, the support plate 16 drives the legs to move downward under the action of gravity, so that the user's legs can remain active during the movement of the wheelchair, achieving the effect of exercise.
[0037] Working principle: When using the wheelchair for the disabled, the controller 14 on the surface of the armrest 9 can be used to control the electric push rod 12 and the motor 13. The motor 13 is started, and the motor 13 drives the rear wheel 5 to rotate, thereby driving the wheelchair to move. When the motor 13 is started, the motor 13 will drive the driving wheel 18 to rotate, and the rotation of the driving wheel 18 drives the driven wheel 17 to rotate intermittently, thereby realizing the movement of the connecting plate 15, and the connecting plate 15 drives the supporting plate 16 to move, so as to move the legs located on the surface of the supporting plate 16, thereby achieving the effect of exercising. When it is necessary to get up, the electric push rod 12 is started, and the electric push rod 12 drives the connecting rod 11 to move upward, and the connecting rod 11 drives the armrests 9 on both sides to move upward, thereby giving the user's arms an upward thrust, achieving the effect of assisting getting up, and increasing the overall practicality.
[0038] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
