Technical Field

[0001] This utility model relates to the field of wheelchair technology, and in particular to a rehabilitation training wheelchair. Background Technology

[0002] A wheelchair is a chair equipped with wheels that can help replace walking. It is an important mobility tool for the injured, sick, and disabled to use at home for rehabilitation, transportation, medical treatment, and outdoor activities. Wheelchairs not only meet the mobility needs of people with limb disabilities and limited mobility, but more importantly, they facilitate the movement and care of family members, and enable patients to exercise and participate in social activities with the help of wheelchairs.

[0003] Existing wheelchairs are mostly electrically driven for ease of use. However, when using a wheelchair on uneven surfaces, the fixed wheels can cause it to tilt, shifting the center of gravity and potentially leading to tipping or secondary injuries. Therefore, we propose a rehabilitation training wheelchair. Utility Model Content

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0018] Example Reference Figures 1-4 A rehabilitation training wheelchair includes a support plate 1, a backrest 14 at one top end of the support plate 1, a seat cushion installed on the top of the support plate 1, and a backrest cushion installed on the side of the backrest 14 near the support plate 1, to improve the comfort of the patient when sitting on the support plate 1.

[0019] First universal wheels 11 are provided on both sides of the bottom of the support plate 1 away from the back plate 14. The first universal wheels 11 are rotatably mounted on the first support frame 9, and the first support frame 9 is fixed on the bottom of the support plate 1. Hub motors 7 are provided on both sides of the other end of the bottom of the support plate 1. Tires 8 are installed along the outer wall of the hub motor 7, and the hub motor 7 is rotatably mounted on the second support frame 2. The second support frame 2 is fixed to the support plate 1, providing power for the wheelchair to move on the ground.

[0020] Specifically, a crossbeam 3 is installed on the bottom of the second support frame 2, and a control box 4 is installed on the crossbeam 3. The control box 4 contains a controller and a battery pack. The controller is connected to the battery pack and the hub motor 7 via wires. In actual use, the controller is one of the control motherboard and the control host, providing power and control for the operation of the hub motor 7.

[0021] The control box 4 is a top-opening enclosure. A cover 5 is detachably installed on the top of the control box 4 to allow for the replacement of the battery pack or maintenance of the controller and battery pack.

[0022] It should be noted that connecting seats 15 are installed on both sides of the back panel 14, and handles 17 are installed on the connecting seats 15. A connecting rod 16 is installed on the bottom of the other end of the handle 17. The bottom of the connecting rod 16 is installed on a fixed seat, and the fixed seat is fixed to the side of the support plate 1. A control joystick and a control button are installed on one of the handles 17. The control joystick and control button are connected to the controller through wires and are used to control the operation and speed of the hub motor 7. That is, in use, the direction of travel of the wheelchair can be controlled by the control joystick, and the start and stop of the hub motor 7 can be controlled by the control button. In actual use, since there are two hub motors 7 at the bottom of the support plate 1, the steering operation of the wheelchair can be provided according to the speed difference of the two hub motors 7.

[0023] In order to provide support strength for the two sets of support frames, a connecting frame 13 is used to connect the side of the first support frame 9 and the side of the second support frame 2.

[0024] Furthermore, a placement plate 12 is provided at the bottom of the end of the support plate 1 away from the back plate 14, and the placement plate 12 is installed on the support beam 10, and the support beam 10 is fixed on the first support frame 9, so as to support and place the patient's feet.

[0025] Furthermore, a fixing plate 18 is installed on the top of the back panel 14 on the side away from the support plate 1, and handles 19 are installed on both ends of the side of the fixing plate 18, so that the wheelchair can be manually pushed when the hub motor 7 is not operating, thereby improving the adaptability of the wheelchair.

[0026] Mounting plates 20 are fixed on both sides of the second support frame 2. Connecting plates 21 are vertically mounted on the sides of the mounting plates 20. First strip plates 23 are rotatably mounted on both sides of the connecting plates 21 via a first rotating shaft 22. A first torsion spring 24 is sleeved on the first rotating shaft 22, with one end of the first torsion spring 24 fixed to the first strip plate 23 and the other end fixed to the connecting plate 21. A second rotating shaft 26 is installed between the bottoms of the two first strip plates 23. A second strip plate 25 is rotatably mounted on the second rotating shaft 26, and a second torsion spring 27 is sleeved on the second rotating shaft 26, with one end of the second torsion spring 27 fixed to the first strip plate 23 and the other end fixed to the second strip plate 25. A second strip plate 25 is rotatably mounted on the bottom of the second strip plate 25. The wheelchair has a second omnidirectional wheel 6. When the wheelchair is moving, the second omnidirectional wheel 6 is placed on the ground on both sides of the wheelchair to provide side support. When the wheelchair encounters an uneven surface and tilts, the unevenness of the surface will exert a pushing force on the second omnidirectional wheel 6, causing the second strip plate 25 and the first strip plate 23, as well as the first strip plate 23 and the connecting plate 21, to rotate. This causes the torsion spring to twist, thereby providing a reverse force to each strip plate. This ensures that the second omnidirectional wheel 6 provides side support to the wheelchair, so as to provide a push force to push the wheelchair back to its initial position in the event of a rollover. It also provides room for movement and cushioning when the wheelchair tilts, so as to adapt to various uneven surfaces and avoid direct hard impact that could damage the strip plates.

[0027] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
