For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.
[0029] Example 1
[0030] This embodiment provides a multi-directional motion training device for lower limb rehabilitation training, such as Figure 1 As shown, it includes a seat cushion 1, a support leg 3 is fixedly installed at the bottom of the seat cushion 1, and a backrest 2 is fixedly installed at the top of the seat cushion 1; the seat cushion 1 is used for patients to sit on, and the backrest 2 provides back support for patients when training their lower limbs.
[0031] like Figure 2 and 2 As shown, it also includes an adjustment component 4, which includes an inner ring 41, a clearance groove 42, a clamping plate 43, an outer ring 45, a threaded ring 46 and a resistance component. The clearance groove 42 is provided at the curved surface of the inner ring 41, and the clamping plate 43 is rotatably connected to the inner ring 41 at the clearance groove 42 through a rotating shaft. A notch is provided on the inner ring of the outer ring 45, and the clamping plate 43 is clamped with the notch of the outer ring 45. A return spring 44 is elastically connected between the clamping plate 43 and the outer ring 45, and the clamping plate 43 can be completely received in the clearance groove 42.
[0032] A threaded ring 46 is fixedly installed at the bottom of the outer ring 45, and a return spring 44 is elastically connected between the clamping plate 43 and the outer ring 45. The clamping plate 43 can be completely retracted into the yield groove 42. The top of the inner ring 41 is fixedly connected to the rotating plate 49. The training component 5 rotates with the rotating plate 49 as the rotation center. The rotating plate 49 rotates reciprocatingly, and the outer ring 45 always rotates in one direction.
[0033] like Figure 3 and 4 As shown, the inner ring of the threaded ring 46 is threadedly connected to the support leg 3, and the resistance assembly is fixedly installed on the side of the outer ring 45 away from the threaded ring 46. The resistance assembly includes a spring telescopic rod 47 and a friction plate 48. The spring telescopic rod 47 is fixedly installed on the side of the outer ring 45 away from the threaded ring 46, and the friction plate 48 is fixedly installed on the other end of the spring telescopic rod 47. The outer ring 45 and the friction plate 48 are both annular structures and are both sleeved on the support leg 3. A rotating plate 49 is provided on the top of the friction plate 48. The elastic force applied to the friction plate 48 by the spring telescopic rod 47 increases the friction force between the friction plate 48 and the rotating plate 49 as pressure, and the spring telescopic rod 47 is extended and retracted to guide the direction of the elastic force application.
[0034] The inner circle of the rotating plate 49 is rotatably connected to the supporting leg 3, and a training assembly 5 is disposed on the top of the rotating plate 49. The patient's lower limbs are placed on the training assembly 5, and the training assembly 5 is driven to rotate by the lower limbs to perform lower limb training. Initially, the spring telescopic rod 47 is compressed to the limit position, and the friction plate 48 exerts the greatest pressure on the rotating plate 49.
[0035] When the inner ring 41 rotates counterclockwise, the clamping plate 43 contacts the outer ring 45 to compress the return spring 44 to fold and completely retract into the retracting groove 42. At this time, the resistance component on the top of the outer ring 45 does not move, and friction resistance is generated between the resistance component and the rotating plate 49, and the patient's lower limbs are trained to resist the friction resistance;
[0036] When the inner ring 41 rotates clockwise, the clamping plate 43 will engage with the interface of the outer ring 45 to drive the outer ring 45 to rotate, thereby causing the threaded ring 46 to rotate and causing the outer ring 45 to move away from the rotating plate 49. Therefore, the resistance component gradually moves away from the rotating plate 49, that is, the resistance of the resistance component to the rotating plate 49 becomes smaller and smaller. As the patient gradually consumes physical strength during training, the resistance he can resist also gradually becomes smaller. By reducing the resistance, the training time of the lower limbs can be extended, and there is no need to frequently adjust the training resistance of the lower limbs.
[0037] In this embodiment, when the patient trains his lower limbs, the training component 5 and the rotating plate 49 are driven to reciprocate, and the rotating plate 49 drives the inner ring 41 to move. The inner ring 41 and the clamping plate 43 cooperate with the outer ring 45 to make the outer ring 45 rotate in one direction, so that the threaded ring 46 rotates to continuously pull the outer ring 45 and the resistance component downward, reducing the friction resistance of the resistance component to the rotating plate 49, thereby achieving the goal that as the training progresses, the patient's lower limbs consume physical strength and gradually reduce the training resistance, so that the patient can always adapt to the training resistance.
[0038] Example 2
[0039] Based on Example 1, this embodiment proposes a multi-directional motion training device for lower limb rehabilitation training, such as Figure 5 As shown, the training assembly 5 includes a training board 51, a first support board 54 and a second support board 56. The end of the training board 51 is fixedly connected to the rotating board 49. The top of the training board 51 is hinged to the first support board 54, the end of the first support board 54 is hinged to the second support board 56, and the bottom of the second support board 56 is slidably connected to the training board 51. The lower limbs of the human body are placed on the top of the first support board 54 and the second support board 56. The first support board 54 and the second support board 56 rotate around the rotating board 49 to perform horizontal rotation exercises on the lower limbs of the patient. The first support board 54 and the second support board 56 are located at the rear of the lower limb knee. The end of the first support board 54 is hinged to the second support board 56, so that the lower limbs of the patient can be exercised by pushing the legs. The lower limbs of the patient can be fixed on the first support board 54 and the second support board 56 by installing straps on the first support board 54 and the second support board 56.
[0040] A slide groove 53 is provided on the top of the training board 51, and a slider 55 is fixedly installed on the bottom of the second support plate 56, and the slider 55 slides in the slide groove 53. The slider 55 reduces the friction between the second support plate 56 and the training board 51, and the slide groove 53 guides the second support plate 56 to prevent the slider 55 and the second support plate 56 from deviating.
[0041] like Figure 5 As shown, a movable leg 52 is fixedly mounted on the bottom of the training board 51, and a roller is rotatably connected to the bottom of the movable leg 52. The training board 51 is supported by the movable leg 52, and the roller is used to reduce the friction between the training board 51 and the ground.
[0042] In this embodiment, the first support plate 54 and the second support plate 56 are rotated around the rotating plate 49 to perform horizontal rotation exercise on the patient's lower limbs. The first support plate 54 and the second support plate 56 are located at the back of the lower limbs' knees. The second support plate 56 is hinged at the end of the first support plate 54 to enable the patient's lower limbs to perform leg-pushing exercise, thereby performing multi-directional training on the patient's lower limbs.
