When the patient sits on the top surface of the seat board 1, the patient's back can lean on one side of the backrest board 2.

[0030] A worm 3 is rotatably connected to one side of the inner cavity of the support plate 2, a drive motor 11 is fixedly installed on one side of the support plate 2, the drive motor 11 can be reversed, the output end of the drive motor 11 passes through the support plate 2 and is fixedly connected to the worm 3, a threaded rod 4 is rotatably connected to the top surface of the inner cavity of the support plate 2 and is located on one side of the worm 3, the bottom end of the threaded rod 4 is rotatably connected to the bottom surface of the inner cavity of the support plate 2, a worm wheel 5 adapted to the worm 3 is fixedly sleeved on the peripheral side of the threaded rod 4, and the worm 3 and the worm wheel 5 are parallel to each other. The drive motor 11 is turned on, so that the drive motor 11 drives the worm 3 to rotate, and the worm 3 can drive the threaded rod 4 to rotate in the inner cavity of the support plate 2 through the matching worm wheel 5. A movable block 6 is provided on the threaded sleeve on the circumferential side of the threaded rod 4. A limiting rod 12 is longitudinally installed on the bottom surface of the inner cavity of the support plate 2 and on one side of the threaded rod 4. The movable block 6 is slidably sleeved on the circumferential side of the limiting rod 12. When the threaded rod 4 rotates, it will drive the movable block 6 to move longitudinally on the circumferential side of the limiting rod 12.

[0031] The inner walls on both sides of the lower half of the inner cavity of the backboard 2 are symmetrically connected with sliding rods 7, the threaded rod 4 is set between the two sliding rods 7, and the limiting rod 12 is also set between the two sliding rods 7. The peripheral sliding sleeves of the two sliding rods 7 are provided with moving blocks 8, and the moving blocks 8 can move laterally around the two sliding rods 7. The top surface of the moving block 8 is hinged with a connecting plate 9, and the free end of the connecting plate 9 is hinged to one side of the movable block 6. One side of the moving block 8 penetrates to one side of the backboard 2 and is fixedly connected with a waist block 10 for driving the patient's waist to swing. When the patient sits on the top surface of the seat board 1, the waist is moved to the inner cavity of the waist block 10 and the waist is fitted against the waist block 10, and a transverse groove for the moving block 8 to move is opened laterally on one side of the backboard 2. When the threaded rod 4 drives When the movable block 6 moves downward, the movable block 6 will drive the connecting plate 9 to move downward. Since the two ends of the connecting plate 9 are respectively hinged to one side surface of the movable block 6 and the top surface of the movable block 8, the connecting plate 9 will drive the movable block 8 to move to the right when it moves downward. Conversely, by rotating the threaded rod 4 in the opposite direction, the movable block 6 and the connecting plate 9 can be driven to move upward, and the connecting plate 9 can drive the movable block 8 to move to the left. In conjunction with the forward and reverse rotation of the drive motor 11, the movable block 8 can be made to reciprocate left and right in the inner cavity of the transverse groove, thereby driving the waist clamping block 10 to move left and right, so that the waist clamping block 10 can assist the patient's waist to swing left and right, avoid the situation where the patient is inconvenient to swing left and right independently, and improve the effect of the auxiliary device on the patient's waist rehabilitation training.

[0032] A micro motor 13 is fixedly connected to the inner wall of one side of the waist block 10, and the micro motor 13 can be rotated forward and reversely. The output shaft of the micro motor 13 is fixedly connected to a threaded shaft 14, and the free end of the threaded shaft 14 is rotatably connected to the inner wall of the other side of the waist block 10. A limit block 15 is provided on the threaded sleeve of the circumference of the threaded shaft 14, and the bottom surface of the limit block 15 is in friction contact with one side of the waist block 10. The inner cavity of the waist block 10 and one side of the threaded shaft 14 are symmetrically provided with a plurality of vertical blocks 16, and the bottom surface of each vertical block 16 is connected to the waist block. The distance from the inner wall of one side of 10 is smaller than the height of the limit block 15. One side of each vertical block 16 penetrates to one side of the waist block 10. The bottom surface of each vertical block 16 is fixedly connected with two springs 17. The free end of each spring 17 is rotatably connected to the inner wall of one side of the waist block 10. The micro motor 13 is turned on, and the micro motor 13 drives the threaded shaft 14 to rotate, so that the threaded shaft 14 drives the limit block 15 to move. Since the distance from the bottom surface of each vertical block 16 to the inner wall of one side of the waist block 10 is smaller than the height of the limit block 15, the bottom surface of each vertical block 16 is fixedly connected to the inner wall of one side of the waist block 10. The height of the limit block 15 is such that the limit block 15 will press against the vertical block 16 in turn after it moves, and the limit block 15 is continued to be moved, so that the vertical block 16 can move along the inclined surface of the limit block 15 in turn, and then the vertical block 16 can stretch the spring 17, so that the upper half of the vertical block 16 can move to one side of the waist block 10. Since the plurality of vertical blocks 16 are arranged in parallel, the limit block 15 can restrict the vertical blocks 16 in turn, so that each vertical block 16 can move to one side of the waist block 10 in turn. When the limit block 15 is moved from the lower part of the vertical block 16 When the vertical block 16 is moved away, the rebound of the spring 17 will drive the vertical block 16 to return to its original position. By repeating the operation, multiple vertical blocks 16 can be moved and returned to one side of the waist clamping block 10 in turn, so that multiple vertical blocks 16 can slightly push the waist attached to one side of the waist clamping block 10 to achieve a massage effect, and a cushion is installed on the top surface of each vertical block 16 to increase the comfort of the patient's waist massage, and the bottom surface of each vertical block 16 can be processed into an arc surface, so that it can better move along the inclined surface of the limit block 15.

[0033] A plurality of vertical rods 18 are symmetrically arranged on the inner walls of both sides of the waist block 10 , and each vertical block 16 is slidably sleeved on the circumference of two vertical rods 18 , ensuring that each vertical block 16 can move in a vertical direction.

[0034] The top surface of the seat board 1 and one side surface of the backrest board 2 are both installed with cushions to increase the patient's comfort, and the thickness of the cushion on one side of the backrest board 2 can be selected according to actual conditions to ensure that after the patient's waist rests on the inner cavity of the waist block 10, the patient's shoulders will not be suspended.

[0035] Working principle:

[0036] In the rehabilitation auxiliary device, the patient sits on the top surface of the seat board 1 and moves his waist to the inner cavity of the waist clamping block 10 and fits the inner wall of the waist clamping block 10. At this time, the driving motor 11 is turned on, and the driving motor 11 drives the worm 3 to rotate, so that the worm 3 drives the worm wheel 5 to rotate, thereby allowing the worm wheel 5 to drive the threaded rod 4 to rotate. When the threaded rod 4 rotates, it will drive the movable block 6 to perform repeated longitudinal movements, so that the movable block 6 will drive the connecting plate 9 to move longitudinally. Since the two ends of the connecting plate 9 are respectively hinged to one side surface of the movable block 6 and the top surface of the movable block 8, when the connecting plate 9 moves longitudinally, it will drive the movable block 8 to perform horizontal reciprocating motion around the two sliding rods 7, thereby driving the waist clamping block 10 to perform horizontal reciprocating motion, allowing the waist clamping block 10 to drive the patient's waist to swing left and right, which can assist the patient's waist training, avoid the situation where the patient is inconvenient to swing his waist independently to perform rehabilitation training, and improve the effect of the auxiliary device on the patient's rehabilitation training.
