The top of the base 1 is hingedly connected with a carrying arm 2, which is a cantilever structure and rotates up and down. The top of the carrying arm 2 is provided with a popliteal fossa support 3 and a leg support 4. The popliteal fossa support 3 is in contact with the popliteal fossa of the leg. One end of the leg support 4 is hingedly connected with the carrying arm 2. The leg support 4 serves to support the lower leg. The up-and-down swinging of the lower leg drives the leg support 4 to swing up and down.

[0033] One side of the carrying arm 2 is provided with a conical turntable 5. One side of the conical turntable 5 is provided with an eccentric shaft 9. Specifically, a support shaft penetrating through the carrying arm 2 is fixedly arranged on one side of the conical turntable 5. One end of the support shaft is fixedly connected with a transmission disc. One end of the eccentric shaft 9 is fixedly connected with one side of the transmission disc. A connecting block 7 is arranged on the base 1. In this embodiment, the connecting block 7 is fixedly connected with the base 1. The connecting block 7 is rotationally connected with the eccentric shaft 9 through a supporting rod 8. When the conical turntable 5 rotates, the carrying arm 2 appears a reciprocating swinging effect. This kind of arrangement can make functional rehabilitation training on the thigh.

[0034] The bottom of the leg support 4 is provided with a dynamic elastic driving group 6 for driving the conical turntable 5 to rotate. Under the action of the dynamic elastic driving group 6, when the leg support 4 is under load, the leg support 4 swings downward in a lagging manner. The rotation speed of the conical turntable 5 increases. When the load on the leg support 4 disappears, the leg support 4 swings upward in a lagging manner. The rotation speed of the conical turntable 5 decreases. In general, when the lower leg exerts force to bend, the leg support 4 swings downward after a delay of several seconds. The frequency of the up-and-down swinging of the thigh increases. When the lower leg relaxes or is lifted, the leg support 4 approaches and fits the lower leg after a delay of several seconds. The frequency of the up-and-down swinging of the thigh decreases. This kind of auxiliary device can train the extension-flexion nerve control function of the lower leg. Moreover, it has the function of assisting the movement of the hip joint, relieving the discomfort caused by the compression of the hip joint, and needs to be noted that the above-mentioned delay function can effectively relieve the fatigue of the patient during rehabilitation training.

[0035] Specifically, the dynamic elastic drive group 6 comprises a guide rod 61, a drive wheel 62, a transmission group 63 and a drive motor 64, the bottom of the leg support 4 is fixedly connected with a support rod 41, the bottom of the support rod 41 is elastically and slidably connected with the guide rod 61, and the sliding axis is parallel to the axis of the conical turntable 5, specifically, one end of the support rod 41 is fixedly provided with a sliding sleeve 411 sleeved on the guide rod 61, the guide rod 61 is sleeved with a supporting spring 613 located on one side of the sliding sleeve 411, and the guide rod 61 is fixedly provided with a check ring 612 located on one side of the supporting spring 613, the supporting spring 613 applies an elastic pushing force to the guide rod 61 to move towards the conical turntable 5. The drive wheel 62 is arranged at one end of the guide rod 61 and abuts against the conical surface of the conical turntable 5, specifically, one end of the guide rod 61 is welded with an L-shaped positioning plate 611, and the middle of the drive wheel 62 is fixedly provided with a transmission shaft 621 rotatably connected at one end with one side of the L-shaped positioning plate 611, and the drive wheel 62 rotates to drive the conical turntable 5 to rotate by means of friction, and further, the outer ring of the drive wheel 62 is covered with a rubber ring 622, and the outer periphery of the conical turntable 5 is covered with a conical rubber sleeve 51, so that the friction between the drive wheel 62 and the conical turntable 5 can be increased.

[0036] The transmission group 63 and the drive motor 64 are both arranged on the guide rod 61, the drive motor 64 controls the drive wheel 62 to rotate through the transmission group 63, specifically, the drive motor 64 is fixedly arranged on one side of the L-shaped positioning plate 611, and the transmission group 63 comprises a bevel gear one 631 and a bevel gear two 632 which are meshed with each other, the bevel gear one 631 and the bevel gear two 632 are fixedly connected with the transmission shaft 621 and the output shaft of the drive motor 64 respectively, that is to say, the drive motor 64 provides continuous rotating power to the drive wheel 62 through the transmission group 63.

[0037] Embodiment 2

[0038] Please refer to Figure 4 , and the difference from embodiment 1 is that the support rod 8 is a flexible telescopic rod structure and comprises a sleeve pipe 81, a connecting spring 82 and a connecting rod 83, one end of the sleeve pipe 81 is hingedly connected with the top of the connecting block 7, the connecting spring 82 is located in the sleeve pipe 81, and one end of the connecting rod 83 is provided with a connecting hole rotatably connected with the eccentric shaft 9, so that the patient's thigh is in an elastic up-down swinging state, and when the patient needs to perform hip joint nerve training, the patient only needs to exert force to overcome the elastic force of the connecting spring 82 in the telescopic support rod 8, which greatly reduces the strength of the hip joint nerve training and effectively assists the patient to perform the hip joint nerve training.

[0039] Embodiment 3

[0040] Please refer to Figure 4, based on the difference between example 1 and example 2, the top horizontal sliding connection of the connecting block 7 and the base 1, when the connecting block 7 slides, under the action of the supporting rod 8, the carrying arm 2 and the components on its top can be greatly lifted, this kind of setting has the advantage of facilitating the butt joint of the popliteal support 3 and the leg support 4 with the patient's leg, that is, after lowering the height of the popliteal support 3 and the leg support 4, the patient places the leg above the popliteal support 3 and the leg support 4, and then controls the sliding of the connecting block 7 to drive the lifting of the carrying arm 2, at this time the popliteal support 3 and the leg support 4 will lift the popliteal and calf from below the patient's leg.

[0041] A lead screw 101 is rotatably connected to the top of the base 1 and penetrates the connecting block 7, one end of the lead screw 101 is fixedly connected with an output shaft, and a control motor 102 is fixedly connected to the end of the lead screw 101, the control motor 102 is started to drive the rotation of the lead screw 101, and the rotation is used to control the reciprocating sliding action of the connecting block 7, which is convenient to operate, and has the advantage of facilitating the butt joint of the device and the patient's leg.

[0042] Working principle: when in use, place the base 1 of the device in front of the external seat, then assist the patient to sit on the seat and control one of the legs to be above the popliteal support 3 and the leg support 4.

[0043] Start the control motor 102 to drive the rotation of the lead screw 101, under the action of the rotation force, the connecting block 7 slides along the base 1, under the action of the supporting rod 8, the carrying arm 2 is lifted, the popliteal support 3 enters the patient's popliteal fossa, and the calf is placed on the leg support 4, at this time the device and the patient are butt jointed.

[0044] Control the driving motor 64 to be energized and started, under the action of the transmission group 63, the driving wheel 62 rotates, under the action of the friction force, the conical turntable 5 rotates, the eccentric shaft 9 moves with the conical turntable 5, under the action of the supporting rod 8, the carrying arm 2 swings up and down with a small amplitude, at this time the patient's thigh swings, and the patient's hip joint is in a state of activity, relieving the discomfort caused by long-term inactivity of the hip joint.

[0045] At this time, when the patient exerts force to control the thigh to be in a stationary state, the popliteal support 3 can timely catch the uncontrollable thigh swinging up and down, avoiding the problem of soreness caused by excessive activity of the thigh.

[0046] When the nerve of the calf needs to be exercised, the patient controls the calf to bend, and the leg support 4 is pressed, at this time the driving wheel 62 presses the inclined surface on the conical turntable 5, and the driving wheel 62 is in a rolling state, at this time the supporting spring 613 will be in a compressed state, and the driving wheel 62 will move close to the small end of the conical turntable 5, this process will make the leg support 4 delay the downward swing relative to the carrying arm 2.

[0047] When the patient controls the lower leg to stretch, the leg support 4 will be separated from the leg support 4, and the supporting spring 613 will be reset. In the process of resetting, the leg support 4 will delay following and adhere to the lower leg. The auxiliary device makes the lower leg stretching and bending movement always in a stable lifting state.

[0048] The driving wheel 62 changes the rotating speed of the conical turntable 5 when moving axially along the conical turntable 5, thereby being able to push the patient's thighs to swing up and down and also being able to change the swinging frequency, thereby reducing the fatigue of the patient during rehabilitation training.

[0049] The above merely describes the preferred embodiments of the present application, but the protection scope of the present application is not limited to this. Any person skilled in the art can make equivalent replacements or changes according to the technical scheme and the inventive concept of the present application within the technical range disclosed by the present application, which should be covered in the protection scope of the present application.
