[0056] In the above scheme, the sliding block 19 is located on one side of the reciprocating screw 18, the first elastic oil bag 20 is set as an annular oil bag, the reciprocating screw 18 passes through the middle of the first elastic oil bag 20, the first oil pipe 21 is located on the side of the third fixed shell 17 away from the adjacent sliding block 19, the first elastic oil bag 20 is fixedly connected to the third fixed shell 17 on the side close to the first oil pipe 21, the first elastic oil bag 20 and the first oil pipe 21 are both filled with hydraulic oil, the limiter 22 is composed of a piston plate and a T-shaped rod, the T-shaped rod is rotatably connected to the piston plate, the lower side of the T-shaped rod is provided with an arc surface that slides with the thread groove of the reciprocating screw 18, and a torsion spring is provided between the T-shaped rod and the sliding block 19, the torsion spring is used to reset the T-shaped rod after the thread groove of the reciprocating screw 18 swings.

[0057] Please refer to Figure 5 and Figure 9-12The power transmission assembly includes: a fourth fixed shell 23, fixedly connected to one side of the third fixed shell 17; a connecting member 24, slidably connected in the fourth fixed shell 23, the connecting member 24 is composed of a fixed ring and a rotating ring, the rotating ring is rotatably connected to the fixed ring, the fixed ring is slidably matched with the fourth fixed shell 23 and is fixedly connected to the second elastic oil bag 25; the second elastic oil bag 25 is fixed in the fourth fixed shell 23, the second elastic oil bag 25 is extruded and matched with the connecting member 24, the second elastic oil bag 25 is connected to the oil guide pipe of the adjacent sliding block 19, and a chamber is provided between the second elastic oil bag 25 and the fourth fixed shell 23.

[0058] In the above scheme, the fourth fixed shell 23 is an annular cylinder, the second elastic oil bag 25 is an annular oil bag, and the second elastic oil bag 25 is fixedly connected to the fourth fixed shell 23 at a position away from the connecting member 24 on the circumference thereof, so that when the second elastic oil bag 25 is squeezed, it can only expand by deforming on the side away from the connecting member 24, and the second elastic oil bag 25 and the oil guide pipe are both filled with hydraulic oil.

[0059] Please refer to Figure 3-Figure 5 and Fig.13 The driving assembly also includes: a rotating shell 26, which is rotatably connected to the moving part 1, the rotating shell 26 is fixedly connected to the reciprocating screw 18, a transmission part is arranged between the rotating shell 26 and the adjacent driving module 5, the rotating shell 26 is slidably connected to the transfer rod 27, one side of the transfer rod 27 is rotatably matched with the transmission rod 12; a first sliding plate 28, which is fixedly connected to the other side of the transfer rod 27, the first sliding plate 28 is fixedly connected to the limiting rod 29, and the limiting rod 29 passes through the rotating shell 26 and is squeezed and matched with the rotating ring of the connecting member 24.

[0060] In the above scheme, the rotating shell 26 is rotatably installed on the moving part 1 through the mounting part, the rotating shell 26 and the axis of the reciprocating screw 18 are on the same straight line, the transmission part between the rotating shell 26 and the driving module 5 is set as a belt and a pulley, the pulley on the driving module 5 is fixed to the side of the driving module 5 away from the driving wheel, and at least two limiting rods 29 are set to ensure that the connecting part 24 is evenly stressed when being squeezed.

[0061] When a patient who lacks independent movement ability needs to use this device to go out or perform rehabilitation exercises, the patient controls the second connecting rod 4 to swing downward through the operating table 401 (the operation is not limited to the patient himself, but can also be assisted by a caregiver. The patient's own operation is taken as an example below). The swing of the second connecting rod 4 drives the first connecting rod 3 to swing downward through the hinge rod until the first connecting rod 3 is in a horizontal state and then stops. During the rotation of the second connecting rod 4, the operating table 401 rotates synchronously to keep the operating table 401 in a horizontal state. After the second connecting rod 4 and the operating table 401 stop, the patient moves his feet to the two foot slots of the moving part 1, then holds the handles on the support part 2, uses the arm force to sit on the cushion, and then fixes the waist with a strap.

[0062] When the patient fixes his waist and needs to use the present device for passive exercise, the patient controls the second connecting rod 4 to swing upward through the operating platform 401, so that the operating platform 401 and the first connecting rod 3 are reset, thereby driving the upper body to move upward through the straps. While the upper body is moved by the straps, the seat cushion applies a supporting force to the patient's buttocks, so that the patient stands up, and then sits down through the operating platform 401 (the action here is consistent with the action of swinging the second connecting rod 4 and the first connecting rod 3 downward when the present device is used), and repeats this process. When the patient uses the present device for autonomous exercise, the patient holds the handles with both hands, uses the force of his arms to pull himself up, and then uses his arms to slowly sit down after standing up (the action here is consistent with the action of the present device for passive exercise), so as to perform autonomous exercise and repeat this process.

[0063] When the patient needs to go out after standing on the device, the two driving modules 5 are controlled by the operating table 401 to drive the driving wheels to rotate so that the movable part 1 moves. While the two driving modules 5 drive the two front wheels to rotate, the two driving modules 5 respectively drive the two fixed blocks 14 to rotate. The two driving modules 5 also drive the two rotating shells 26 to rotate synchronously through the transmission parts. The rotation of the two rotating shells 26 respectively drives the two reciprocating screws 18 to rotate. The rotation of the two fixed blocks 14 drives the two rotating blocks 13 to rotate respectively through the telescopic rods thereon. At the same time, the centrifugal block inside the fixed block 14 is subjected to the centrifugal force and moves in the direction away from the axis of the fixed block 14. At this time, if the movable part 1 makes a linear motion, the rotation speed of the two driving modules 5 is consistent, and the centrifugal force exerted on the centrifugal blocks in the two fixed blocks 14 is consistent and transmitted to the two rotating blocks through the pull rope. The pulling force of 13 is consistent, so that the transmission rod 12 remains stationary. When the rotation speeds of the two fixed blocks 14 are different, it means that the movable part 1 is turning. The following text is based on the forward direction when the patient sits on the cushion of the first connecting rod 3. When the rotation speed of the right fixed block 14 is greater than the rotation speed of the left fixed block 14, it means that the movable part 1 is turning left. At this time, the centrifugal force exerted on the centrifugal block in the right fixed block 14 is greater than the centrifugal force exerted on the centrifugal block in the left fixed block 14. The right fixed block 14 will pull the transmission rod 12 to the right through the pull rope of the centrifugal block inside it and the rotating block 13, compressing the second elastic member between the transmission rod 12 and the second fixed shell 11, and the transmission rod 12 moves to the right through the rotating block 13 on the left and the pull rope on the left rotating block 13 to pull the centrifugal block in the left fixed block 14 toward the direction close to the axis of the fixed block 14.

[0064] During the process of the transmission rod 12 moving to the right, the transmission rod 12 drives the two transmission rods 27 to move to the right. At this time, the right transmission rod 27 drives the first sliding plate 28 to move in the direction close to the right third fixed shell 17. The movement of the first sliding plate 28 drives the two limit rods 29 thereon to move. During the movement of the limit rod 29, it contacts and squeezes the connecting member 24 to move. The connecting member 24 moves to squeeze the second elastic oil bag 25 so that the hydraulic oil inside it enters the cavity of the sliding block 19 through the oil guide pipe and pushes the limit member 22 downward. When the limit member 22 is blocked by the reciprocating screw 18, the connecting member 24 continues to squeeze the second elastic oil bag 25 to make it expand into the chamber of the fourth fixed shell 23 until the transmission rod 12 compresses the second elastic member between it and the second fixed shell 11 to the limit and stops.

[0065] After the transmission rod 12 stops moving, the second elastic oil bag 25 stops expanding. During this process, the reciprocating screw 18 continues to rotate. When the thread groove of the reciprocating screw 18 and the limiter 22 are in corresponding positions, the expanded second elastic oil bag 25 shrinks a part, so that the hydraulic oil in the second elastic oil bag 25 enters the cavity of the sliding block 19 through the oil guide pipe, so that the limiter 22 moves downward again and limits each other with the thread groove of the reciprocating screw 18. At this time, the reciprocating screw 18 can drive the sliding block 19 to move through the limiter 22, and the sliding block 19 moves to squeeze the first elastic oil bag 20 so that the hydraulic oil inside it enters the first fixed shell 7 through the first oil pipeline 21. The hydraulic oil entering the first fixed shell 7 pushes the piston rod 8 moves to the left and compresses the first elastic member between the piston rod 8 and the first fixed shell 7. The piston rod 8 moves to the left and synchronously drives the counterweight block 6 to move to the left, so that the center of gravity of the movable part 1 is shifted to the left when the movable part 1 turns left, avoiding the center of gravity shifting to the right when turning left and causing the movable part 1 to tip over to the right, thereby improving the safety of the patient when using the device for movement. The rotation speed of the drive module 5 is transmitted to the reciprocating screw 18 through the rotating shell 26 to control the squeezing speed of the sliding block 19 on the first elastic oil bag 20, so that the moving speed of the counterweight block 6 is proportional to the turning angle, so that the position of the center of gravity of the movable part 1 can be accurately adjusted according to the different turning angles of the movable part 1, thereby improving the stability of the movable part 1 when turning.

[0066] After the turn, the moving part 1 resumes straight-line travel, the rotation speeds of the left and right fixed blocks 14 resume consistency, the centrifugal forces on the centrifugal blocks in the two fixed blocks 14 are equal, the pulling forces exerted on the transmission rod 12 by the two fixed blocks 14 are balanced, and the transmission rod 12 is reset under the action of the second elastic member between it and the second fixed shell 11, and the centrifugal blocks in the right fixed block 14 are reset to the middle of the fixed block 14 slide groove, and the centrifugal blocks in the left fixed block 14 are reset to the middle of the fixed block 14 slide groove under the action of centrifugal force, the transmission rod 12 is reset and drives the first sliding plate 28 to reset through the transfer rod 27, and the first sliding plate 28 drives the two limit rods 29 to reset, so that the limit rod 29 releases the squeezing of the connecting member 24 and thereby releases the squeezing of the second elastic oil bag 25, and the second elastic oil bag 25 is reset under the action of its own elastic force and The hydraulic oil in the cavity of the sliding block 19 is pumped back into the second elastic oil bag 25 through the oil guide pipe. The hydraulic oil in the cavity of the sliding block 19 flows back and drives the limit piece 22 to reset, so that the limit piece 22 contacts the thread groove of the reciprocating screw 18 and limits the position. At this time, the sliding block 19 stops moving and the pressure on the first elastic oil bag 20 disappears. Then the elastic force of the first elastic piece between the first fixed shell 7 and the piston rod 8 is released and drives the piston rod 8 to reset. The piston rod 8 is reset and pushes the hydraulic oil in the first fixed shell 7 back into the first elastic oil bag 20 through the first oil delivery pipe 21. The hydraulic oil flowing back into the first elastic oil bag 20 causes the first elastic oil bag 20 to resume expansion and push the sliding block 19 to reset in the direction away from the fourth fixed shell 23 until the elastic force of the first elastic piece in the first fixed shell 7 is completely released and drives the counterweight 6 to reset to the right.

[0067] When the movable part 1 turns right, the rotation speed of the left fixed block 14 is greater than that of the right fixed block 14, so that the centrifugal force provided by the centrifugal block in the left fixed block 14 is larger, thereby pulling the transmission rod 12 to the left, so that the rotating shell 26 on the left squeezes the connecting piece 24 and the second elastic oil bag 25 in the left fourth fixed shell 23 through the limit rod 29, so that the reciprocating screw 18 on the left drives the sliding block 19 on the left to move, so that the hydraulic oil entering the left first fixed shell 7 pushes the piston rod 8 to move right, and moves the counterweight block 6 on the left to the right, thereby balancing the center of gravity of the movable part 1 turning right. After the turn is completed, the reset action of the left part is consistent with the reset action of the right part at the end of the left turn.

[0068] Example 2: Based on Example 1, please refer to Fig. 9 , Fig.13 and Fig.14, also includes: a delay component, the number of which is consistent with the number of the rotating shell 26, and is arranged in the rotating shell 26. The delay component is used to delay the resetting of the first elastic oil bag 20. The delay component includes: a second sliding plate 30, which is sealed and slidably connected to the rotating shell 26, and a third sliding plate 31 is sealed and slidably connected in the rotating shell 26. The side of the transmission rod 27 away from the transmission rod 12 passes through the first sliding plate 28, the third sliding plate 31, the rotating shell 26 and the reciprocating screw 18 and is located in the third fixed shell 17. The transmission rod 27 is rotatably matched with the rotating shell 26 and the reciprocating screw 18. The transmission rod 27 is sealed and slidably matched with the first sliding plate 28 and the third sliding plate 31. The second sliding plate 30 is fixedly connected to the transmission rod 27 and is located between the first sliding plate 28 and the third sliding plate 31. The first sliding plate 28 is fixedly connected with a third elastic member. The third elastic member of the first sliding plate 28 The parts are squeezed and matched with the rotating shell 26, the second sliding plate 30 is provided with an oil guide hole, and the side of the transmission rod 27 away from the transmission rod 12 is rotatably connected to the L-shaped rod 32 through a connecting ring; the connecting shell 33 is fixed to the inner circumference of the third fixed shell 17, the connecting shell 33 is provided with a first guide hole, and a sealing plate 34 is slidably connected in the connecting shell 33, the sealing plate 34 is fixed to the L-shaped rod 32, and the sealing plate 34 is provided with a second guide hole, the sealing plate 34 is sealed and matched with the first guide hole of the connecting shell 33, and the second guide hole of the sealing plate 34 is communicated and matched with the first guide hole of the connecting shell 33, and the first guide hole of the connecting shell 33 is communicated and matched with the first elastic oil bag 20, a one-way valve is provided in the first oil pipeline 21, the first oil pipeline 21 is fixedly connected and communicated with the second oil pipeline 35, and the second oil pipeline 35 passes through the third fixed shell 17 and is communicated with the first guide hole of the connecting shell 33.

[0069] In the above scheme, the axis of the transmission rod 27 is on the same straight line as the axis of the reciprocating screw 18, the first sliding plate 28 and the third sliding plate 31 and the rotating shell 26 together form a closed oil chamber, hydraulic oil is filled between the first sliding plate 28 and the third sliding plate 31, the third elastic member between the first sliding plate 28 and the rotating shell 26 is set as a spring, the connecting shell 33 is located between the third fixed shell 17 and the first elastic oil bag 20, the first guide hole of the connecting shell 33 and the second guide hole of the sealing plate 34 are initially connected, the side of the first oil pipe 21 close to the first elastic oil bag 20 is a hard pipe, the one-way valve in the first oil pipe 21 is located inside the hard pipe area of ​​the first oil pipe 21, the flow direction of the one-way valve in the first oil pipe 21 is from the side of the one-way valve close to the first elastic oil bag 20 to the side of the one-way valve away from the first elastic oil bag 20, and the second oil pipe 35 is filled with hydraulic oil.

[0070] When the turning amplitude of the movable part 1 is too large, the transmission rod 27 drives the second sliding plate 30 to move. Since the flow volume of the oil guide hole on the second sliding plate 30 is small, the second sliding plate 30 pushes the first sliding plate 28 to move through the hydraulic oil, thereby driving the limit rod 29 to move, and squeezing the third elastic member between the first sliding plate 28 and the rotating shell 26. During the movement of the first sliding plate 28, the first sliding plate 28 moves and synchronously drives the third sliding plate 31 to move through the hydraulic oil. The movement of the transmission rod 27 will also synchronously drive the L-shaped rod 32 to move in the direction away from the fourth fixed shell 23. The movement of the L-shaped rod 32 drives the blocking plate 34 to move, so that the blocking plate 34 blocks the first guide hole of the connecting shell 33. The subsequent actions of the limit rod 29 squeezing the connecting part 24 and the second elastic oil bag 25 are consistent with the above actions, and finally the hydraulic oil in the first elastic oil bag 20 enters the first fixed shell 7 through the one-way valve in the first oil pipeline 21, so that the counterweight block 6 adjusts to adapt to the center of gravity of the movable part 1 when turning.

[0071] In the process of the reciprocating screw 18 driving the sliding block 19 to move, the elastic force of the third elastic member between the first sliding plate 28 and the rotating shell 26 is gradually released and pushes the first sliding plate 28 to move in the direction close to the second sliding plate 30. At this time, the position of the second sliding plate 30 remains unchanged, and the hydraulic oil between the first sliding plate 28 and the second sliding plate 30 enters between the second sliding plate 30 and the third sliding plate 31 through the oil guide hole of the second sliding plate 30 and pushes the third sliding plate 31 to move until the elastic force of the spring between the first sliding plate 28 and the rotating shell 26 is completely released to drive the first sliding plate 28 and the third sliding plate 31 to reset. At this time, the squeezing of the connecting member 24 by the limit rod 29 disappears, so that the reciprocating screw 18 no longer drives the sliding block 19 to move, and the sliding block 19 stops squeezing the first elastic oil bag 20, thereby stopping the movement of the counterweight block 6. At this time, due to the action of the one-way valve in the first oil delivery pipe 21, the hydraulic oil entering the first fixed shell 7 will not flow back, thereby maintaining the current position of the piston rod 8 until the moving member 1 ends turning.

[0072] After the moving part 1 finishes turning, the transmission rod 12 drives the transmission rod 27 to reset, thereby driving the second sliding plate 30 to reset. The reset of the transmission rod 27 drives the L-shaped rod 32 to reset, and the L-shaped rod 32 drives the blocking plate 34 to move, so that the second guide hole of the blocking plate 34 is connected to the first guide hole of the connecting shell 33. At this time, the hydraulic oil entering the first fixed shell 7 flows back to the first elastic oil bag 20 through the first oil pipe 21 and the second oil pipe 35 thereon, so that the first elastic oil bag 20 expands and drives the sliding block 19 to reset, and the first sliding plate 28 is reset during the turning process through the oil guide hole of the second sliding plate 30, so that the counterweight block 6 stops moving after adapting to the turning angle and adjusting the center of gravity to the optimal position, and keeps the current position unchanged, so that the moving part 1 always maintains the optimal center of gravity position when the turning amplitude is large, thereby improving the stability of the moving part 1 during the turning process.
