DETAILED DESCRIPTION

[0031] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0032] Example 1

[0033] like Figures 1-9 As shown, the present invention provides a physical fitness recovery device for sports injuries, comprising a wheelchair 1, a fixed block 2 being mounted on the bottom side of the wheelchair 1, a movable block 4 being movably connected to the outside of the fixed block 2, a movable plate 7 being slidably connected to the outside of the movable block 4, a recovery assembly being disposed on the outside of the movable block 4 and the movable plate 7, the recovery assembly comprising a training plate 11 disposed on the movable block 4, a rack 12 disposed on the training plate 11, and a gear 10 meshing with the rack 12;

[0034] A separation assembly for the gear 10 and the rack 12 is commonly provided between the movable block 4 and the movable plate 7, and the separation assembly includes a first sliding block 17 provided on the movable block 4, the first sliding block 17 is fixedly connected to the movable plate 7, a baffle 28 is slidably connected to the outside of the training plate 11, a placement groove 29 is provided on the outside of the training plate 11, a first round rod 3 is installed on the outside of the fixed block 2, the movable block 4 is slidably connected to the outside of the first round rod 3, a first servo motor 5 is installed at the bottom of the wheelchair 1, a first threaded rod 6 is installed on the end of the output shaft of the first servo motor 5, and the first threaded rod 6 is threadedly connected to the movable block 4, a second sliding groove 22 is provided on the outside of the training plate 11, a second round rod 25 is installed on the inner side of the second sliding groove 22, a second sliding block 23 is installed on the outside of the movable block 4, the second sliding groove 22 and the second round rod 25 are both slidably connected to the second sliding block 23, and a spring 24 is commonly installed between the second sliding block 23 and the side wall of the second sliding groove 22;

[0035] A second servo motor 14 is installed on the outside of the movable plate 7, and a second bevel gear 15 is installed on the end of the output shaft of the second servo motor 14. A support block 8 is installed on the outside of the movable plate 7, and the external rotation of the support block 8 is connected to the first rotating rod 9. The end of the first rotating rod 9 close to the second bevel gear 15 is installed with a first bevel gear 13 that can mesh with the second bevel gear 15. The gear 10 is installed on the end of the first rotating rod 9 away from the first bevel gear 13. A fourth sliding groove 30 is opened on the outside of the wheelchair 1, and the rack 12 is installed on the inner side of the fourth sliding groove 30, and the size of the opening of the fourth sliding groove 30 is adapted to the size of the second bevel gear 15.

[0036] In this embodiment, after a sports injury, the patient can sit in the wheelchair 1 to move and rest. When recovery training is needed, the patient can put his feet on the placement slots 29, and then the second servo motor 14 can be started, and the second bevel gear 15 can be driven by the second servo motor 14 to rotate back and forth. Since the second bevel gear 15 is meshed with the first bevel gear 13, the second servo motor 14 can drive the first rotating rod 9 to rotate through the second bevel gear 15 and the first bevel gear 13, and at the same time drive the second bevel gear 15 to rotate. Since the second bevel gear 15 is meshed with the rack 12, the second bevel gear 15 is meshed with the rack 12. When the wheel 15 rotates, it drives the training board 11 to move back and forth, so that the training board 11 moves back and forth along the second sliding groove 22 and the second round rod 25 through the second sliding block 23. When the training board 11 moves back and forth, it drives the patient's feet to move back and forth, thereby achieving back and forth flexion and extension of the legs. When flexion and extension training is not required, the training board 11 can also be driven to move by the second bevel gear 15, thereby adjusting the position of the placement groove 29 on the training board 11, so that the patient can find a more comfortable position to place his feet. When the wheelchair 1 and the training board 11 are not needed, the training board 11 can also be retracted to the bottom of the wheelchair 1 to reduce the space occupied.

[0037] When the legs need to move up and down, the first servo motor 5 can be activated, and the first threaded rod 6 can be rotated by the first servo motor 5. The force generated by the rotation of the first servo motor 5 can drive the movable block 4 to move up and down along the first round rod 3, thereby driving the feet on the training board 11 to move up and down, thereby achieving up and down movement of the legs. This allows the patient to perform leg flexion and extension exercises and up and down leg movements, which can help improve blood circulation in the injured leg and reduce swelling and congestion. Improved blood circulation is crucial for tissue recovery and can maintain or enhance leg muscle strength and maintain normal joint mobility.

[0038] Example 2

[0039] like Figures 1-9 As shown, based on the first embodiment, a first sliding groove 16 is provided on the outside of the movable block 4, and the first sliding block 17 is slidably connected to the inner side of the first sliding groove 16. The inner side of the first sliding groove 16 is rotatably connected to the second threaded rod 18, and the second threaded rod 18 is threadedly connected to the first sliding block 17. A third bevel gear 19 is installed on the outside of the second threaded rod 18. The outside of the movable block 4 is rotatably connected to the second rotating rod 20, and the second rotating rod 20 extends to one end inside the first sliding groove 16 and is equipped with a fourth bevel gear 21 that can mesh with the third bevel gear 19. A third sliding groove 26 is provided on the outside of the training board 11, and the inner side of the third sliding groove 26 is rotatably connected to the third threaded rod 27. The baffle 28 is slidably connected to the inner side of the third sliding groove 26, and the baffle 28 is threadedly connected to the third threaded rod 27.

[0040] In this embodiment, when the patient is performing recovery training, active or passive training can be selected according to the degree of injury. During passive training, the training plate 11 can be directly driven back and forth by the second servo motor 14, thereby realizing passive training. If the patient needs active training, the second rotating rod 20 can be rotated at this time. Since the fourth bevel gear 21 is engaged with the third bevel gear 19, the second rotating rod 20 can be rotated to drive the second threaded rod 18 to rotate. The force generated by the rotation of the second threaded rod 18 can drive the first sliding block 17 to move along the first sliding groove 16, and at the same time drive the movable plate 7 to move. When the movable plate 7 moves, it drives the second bevel gear 15 to move, so that the second bevel gear 15 and the rack 12 are engaged. Separated, at this time, the patient can use both feet to drive the training board 11 to move back and forth, so that the training board 11 moves back and forth along the second round rod 25 and the second sliding groove 22 through the second sliding block 23, and then active training is achieved through the force of the spring 24 expansion and contraction. Before active training, the third threaded rod 27 can be rotated, and the force generated by rotating the third threaded rod 27 drives the baffle 28 to rotate back and forth along the third sliding groove 26, thereby limiting the distance of the training board 11 moving back and forth, thereby limiting the angle of the patient's leg flexion and extension movement, making it safer to make recovery training, avoid exceeding the training limit, and causing damage to the legs, realizing active movement and passive movement, adapting to different rehabilitation needs, and improving rehabilitation efficiency.

[0041] While 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 these embodiments without departing from the principles and spirit of the invention, and that the scope of the invention is defined by the appended claims and their equivalents.
