Description

Technical Field

[0001] The utility model belongs to the field of rehabilitation auxiliary training equipment, and particularly relates to an auxiliary rehabilitation system. Background Technique

[0002] When patients are undergoing rehabilitation training, most of them have difficulty moving their lower limbs. As the foundation support of the whole body, the lower limbs also play a key role in the balance, support and stability of other parts of the body. Once the lower limbs are not active for a long time, it is easy to cause muscle atrophy of the lower limbs, which will further affect the normal life of the patients. At present, in order to help the patients with difficulty in moving their lower limbs recover as soon as possible, they will be timely helped to carry out functional exercises of the lower limbs. The existing lower limb trainers have simple training actions and can only make the lower limbs of the patients perform simple reciprocating movements, and cannot help the lower limbs of the patients to carry out effective multi-mode training.

Specific implementation manner

[0022] As Figures 1-5 shown, the present utility model provides an auxiliary rehabilitation system, including a mounting plate 1. At the upper end of the mounting plate 1, there are a connecting plate 2 and a swing plate 3 whose one ends are hinged to each other. The swing plate 3 is located above the connecting plate 2. A pushing structure is installed on the surface of the connecting plate 2. Driven by the pushing structure, the swing plate 3 can be pushed to swing upward repeatedly. A pedal 7 that can move back and forth is installed on the surface of the swing plate 3. The pedal 7 can move along the length direction of the pedal 7 as the swing plate 3 swings up and down.

[0023] The two connecting plates 2 are respectively slidably connected to the mounting plate 1, so that the two connecting plates 2 can move outward. A driving structure is installed at the upper end of the mounting plate 1 and can drive the two connecting plates 2 to move outward simultaneously.

[0024] When the device is in use, the foot can be placed on the upper end of the pedal 7. By driving the pushing structure to push the swing plate 3 to swing upward, the patient's leg can be lifted. When the patient's leg is lifted, the pedal 7 can be controlled to move on the upper end of the swing plate 3 by the leg, playing a role in stretching the leg. It can be controlled according to the needs of the user. And when exercising the patient's leg, the connecting plate 2 can be driven to move outward by controlling the driving structure, so that the user's legs can open and close outward, facilitating the user to move the legs.

[0025] At the front and rear sides of the inner ends of the two connecting plates 2, mounting rods 4 are respectively fixedly connected. Mounting holes are respectively opened on the surface of the mounting plate 1 corresponding to the mounting rods 4. The mounting rods 4 are respectively slidably connected to the mounting rods 4, which can enable the connecting plates 2 to move outward and reciprocate stably, facilitating the user to carry out rehabilitation exercises.

[0026] The driving structure includes a reciprocating lead screw 12 which is respectively rotatably connected to the surface of the connecting plate 2 and is perpendicular to the connecting plate 2. A linkage rod 14 is slidably connected between the left and right corresponding reciprocating lead screws 12. The linkage rod 14 is rotatably connected to the surface of the mounting plate 1. A mating gear 15 is fixedly connected to the surface of the linkage rod 14. A driving gear 16 is meshed with the rear side of the mating gear 15. A driving motor 17 is fixedly connected to the left end of the driving gear 16. Limiting sleeves 13 are respectively sleeved on the surfaces of the reciprocating lead screws 12. The limiting sleeves 13 are fixedly connected to the surface of the mounting plate 1. A pin shaft 20 is fixedly connected to the inner wall of the limiting sleeve 13. The pin shaft 20 is meshed with the reciprocating lead screw 12. A guiding groove 18 with opposite thread helix directions at both ends and connected end to end is formed on the surface of the reciprocating lead screw 12. The pin shaft 20 is meshed with the guiding groove 18. When the pin shaft 20 is fixed and the reciprocating lead screw 12 rotates, the two reciprocating lead screws 12 can move reciprocally outwards through the meshing of the guiding groove 18 and the pin shaft 20, thereby pushing the connecting plate 2 to move reciprocally outwards.

[0027] A baffle 21 is respectively fixedly connected to the edge positions of the inner ends of the two reciprocating lead screws 12 to prevent the reciprocating lead screws 12 from disengaging from the limiting sleeves 13.

[0028] Linkage holes 19 with two sides recessed inwards on the circumferential surface are respectively formed at the inner ends of the two reciprocating lead screws 12. The circumferential surface of the linkage rod 14 is recessed inwards along the axial direction, so that the linkage rod 14 can be meshed with the linkage holes 19, enabling the connecting rod to not only axially move inside the linkage holes 19, but also drive the reciprocating lead screw 12 to rotate when the linkage rod 14 rotates. Furthermore, when the reciprocating lead screw 12 moves outwards, the linkage rod 14 can also drive the reciprocating lead screw 12 to rotate, facilitating the driving of the swing plate 3.

[0029] A connecting chute 11 is formed along the length direction at the upper end of the swing plate 3. A connecting slider 5 is slidably connected inside the connecting chute 11. A moving plate 6 is fixedly connected to the upper end of the connecting slider 5. Pedals 7 are respectively hinged to the inner ends of the moving plate 6. Rectangular concave surfaces are respectively formed at the upper and lower ends of the pedals 7 for placing the feet of the user. When the moving plate 6 moves, the connecting slider 5 can move inside the connecting chute 11, improving the stability of the pedals 7 during movement.

[0030] The driving structure includes a cam 9 fixedly connected to the outer end of the reciprocating lead screw 12. An articulated rod 8 is hinged at a non-central position of the cam 9, and the other end of the articulated rod 8 is hinged to the bottom of the moving plate 6. When the reciprocating lead screw 12 rotates, it can drive the cam 9 to rotate. Then, when the cam 9 rotates, it can drive the moving plate 6 to move under the drive of the articulated rod 8. Moreover, when the cam 9 rotates, the convex part of the cam 9 abuts against the lower connecting plate 2, which can indirectly push the swing plate 3 to swing upward, achieving the effect of controlling the pedal 7 to move while the swing plate 3 swings, facilitating the rotation of the patient's leg. And under the engagement of the pin shaft 20 and the reciprocating lead screw 12, the swing plate 3 can also move outward while swinging upward, further improving the convenience of the device for assisting the user in moving the patient's leg.

[0031] A pulley 10 is rotatably connected to the surface of the connecting plate 2 below the cam 9. When the cam 9 rotates, the convex part of the cam 9 can abut against the pulley 10, thereby reducing the friction and facilitating the swing of the swing plate 3.

[0032] The specific embodiments described herein are merely illustrative of the spirit of the present invention. Those skilled in the art to which the present invention pertains can make various modifications or supplements to the described specific embodiments or use similar methods to replace them, but will not deviate from the spirit of the present invention or exceed the scope defined by the appended claims.
