Description

Technical Field

[0001] The present invention relates to the field of movement assisted training, and particularly relates to an assisted training device for patients with movement disorders. Background Art

[0002] Movement disorder diseases, also known as extrapyramidal diseases, mainly show disorders in the regulation of voluntary movement, with muscle strength, sensation, and cerebellar function unaffected. They result from basal ganglia dysfunction and are usually divided into hypertonia - hypokinesia and hypotonia - hyperkinesia. The clinical manifestations of movement disorder diseases mainly include involuntary movements, absence or slowness and weakness of work paralysis, abnormal posture and muscle tone, etc.

[0003] In order to help patients with movement disorder diseases to carry out rehabilitation training, passive movement can be used through the use of auxiliary devices to enhance muscle strength, improve joint mobility, and enhance balance and coordination abilities. When some existing auxiliary devices, especially those for leg muscle training, are in use, power assistance for separately supporting the thigh, calf, and sole of the leg is used to adjust the joint flexion of the patient to achieve the purpose of enabling the patient to perform walking movement training, so as to achieve the purpose of assisted training. This training method is only suitable for patients who need to be completely assisted by the device to walk and do not have the ability to walk by themselves. For patients with mild walking function disorders, the patient's own initiative should be the main force. Therefore, different patients should have different training method intensities suitable for different degrees or different stages, while the training intensity and method of existing auxiliary devices cannot be changed, and the applicable range is small. Summary of the Invention

[0004] Aiming at the deficiencies of the above - mentioned existing technologies, the technical problem to be solved by the present invention is: to provide an assisted training device for patients with movement disorders to solve the problem of the single training mode of existing auxiliary devices.

[0005] To solve the above - mentioned technical problem, a technical solution adopted by the present invention is: to provide an assisted training device for patients with movement disorders, including a bracket, a limb fixation unit, and a leg training unit. There is a training space on the bracket for a wheelchair or a patient to move into it; the limb fixation unit includes a first power part installed on the bracket and a limb fixation part hoisted on the first power part and used for sleeving on the patient's limb. The limb fixation part is located in the training space, and the first power part is used to drive the limb fixation part to lift and lower; the leg training unit includes a first leg training part movably installed at the bottom of the training space for driving the patient's leg to swing, a second leg training part movably installed at the bottom of the training space for assisting the patient to walk, and a position - switching structure for enabling the first leg training part and the second leg training part to perform position switching in the training space.

[0006] Further, the limb fixing part includes a first protective belt which is hoisted on the first power part through a first connecting belt and is used for passing through the upper body of the patient, and a second protective belt which is hoisted on the first power part through two second connecting belts and is used for passing through the buttocks of the patient.

[0008] Further, the two second winding parts are drivingly connected to operate synchronously.

[0009] Further, the first leg training part includes a first base movably installed at the bottom of the training space, a base installed on the top of the first base, and two pedals rotatably installed on both sides of the base for the patient to step on staggeredly with both feet. Shoe supports for the patient's toes or shoe tips to penetrate into are arranged on the two pedals, and an elastic surrounding belt for sleeving on the patient's heel position is also connected to the shoe supports.

[0010] Further, the first leg training part further includes a second power part arranged in the base and drivingly connected to the pedals.

[0011] Further, the base is slidably arranged longitudinally on the first base.

[0012] Further, the second leg training part includes a second base movably installed at the bottom of the training space and a stepper arranged on the second base. The heights of the stepper, the first base, the second base and the bottom surface of the training space are all the same.

[0013] Further, the cutting structure includes a bottom groove recessed from the bottom surface of the training space, at least two slide rails protruding transversely on the bottom wall of the bottom groove along a direction perpendicular to the longitudinal direction, and a compensation plate. The first base and the second base are both slidably arranged adjacent to each other in the bottom groove along the transverse direction through the slide rails, and the compensation plate is placed adjacent to the first base on the top of each slide rail; an opening for the compensation plate to pass through is longitudinally opened on one side of the bottom groove corresponding to the second base and the compensation plate along the longitudinal direction.

[0014] Further, two handrails are respectively rotatably installed and received on both sides of the bracket. Both of the two handrails have free ends that can swing freely, and the two free segments are detachably connected and are located on the side of the limb fixing part when connected.

[0015] The auxiliary training device for patients with movement disorders of the present invention has at least the following beneficial effects: By providing a limb fixing unit to relatively fix the upper body and buttocks of the patient, the first power unit can adjust the height of the limb fixing part to facilitate the use by patients of different heights, with a wider range of use; By providing a cutting structure, the first leg training part and the second leg training part can change positions, so that when assisting the patient in training, one of the training parts is located below the limb fixing part. Thus, according to the conditions of different patients, the first leg training part can be used for patients with more severe leg disorders, and the second leg training part can be used for patients with less severe leg disorders, so that the training mode can be switched to adapt to different patients.

Detailed implementation manners

[0026] The present invention will be further described below with reference to the accompanying drawings.

[0027] Please refer to Figures 1 to 7 , the auxiliary training device for patients with movement disorders of the present invention includes a bracket 1 with a training space inside, a limb fixing unit installed on the bracket 1 and located inside the training space, a leg training unit installed on the bracket 1 and located at the bottom of the training space, and two handrail parts 4 arranged on the bracket 1 and capable of being stored and placed. The training space is used for a patient or a wheelchair carrying the patient to move into it, so that a patient with inconvenient movement can move into the training space through the wheelchair, reducing trouble and improving convenience; the limb fixing unit is used for supporting the upper body of the patient in a hoisting manner by putting on the upper body of the patient after the patient moves into the training space, so that the patient can use the leg training unit without effort on the upper body, reducing the stress on the patient's legs; the leg training unit is used for assisting the patient to perform leg movements, thereby exercising the patient's leg muscles and achieving the purpose of auxiliary training; when training, the patient can hold the handrail parts 4 with hands to relatively stably support the hoisted upper body, thereby avoiding excessive shaking of the upper body and affecting the training effect.

[0028] Please refer to Figure 1 , Figure 2 and Figure 5, in this embodiment, the bracket 1 includes a bottom plate 11 with a horizontal support surface on the top surface, four vertical frames 12 fixedly arranged in a rectangular array along a vertical direction on the horizontal support surface, and a cross frame 13 connected end to end at the top ends of each vertical frame 12. Among them, both ends of any one cross frame 13 are fixedly connected to the top ends of two adjacent vertical frames 12, and adjacent two cross frames 13 are connected by mortise and tenon joints. In this embodiment, the bottom plate 11 is made of an alloy material and is solid inside to ensure that it has sufficient stiffness to support each structure. In order to facilitate supporting the patient, the vertical frames 12 and the cross frame 13, the bottom plate 11 has a sufficient thickness, such as more than 10 cm, to ensure that it has sufficient weight. In order to facilitate the wheelchair to move into the training space, the direction parallel to the length of the bottom plate 11 is defined as the longitudinal direction, the direction parallel to the width of the bottom plate 11 is defined as the transverse direction, and the vertical direction corresponds to the thickness direction of the bottom plate 11. A moving inclined surface 14 extending outside the training space and inclined downward and narrowing away from the training space is formed on one side edge of the bottom plate 11 along the longitudinal direction. The lowest point of the moving inclined surface 14 extends to be flush with the ground to facilitate the wheelchair or the patient to move from the moving inclined surface 14 into the training space. The vertical frames 12 and the cross frame 13 are made of metal materials and can be set to be hollow or solid, but it should be ensured that the stiffness between the vertical frames 12 and the cross frame 13 is sufficient to bear and support the weight of multiple people. The cross frame 13, the vertical frames 12 and the bottom plate 11 are connected and supported with each other to form a relatively stable structure. The training space is formed on the top surface of the bottom plate 11 and the inner sides of the cross frame 13 and the vertical frames 12. The training space should ensure sufficient width to accommodate the wheelchair. Therefore, the length, width and height of the training space are much larger than the dimensions of a conventional wheelchair and the height dimensions of an adult.

[0029] Please refer to Figure 1 and Figure 5, in this embodiment, the limb fixation unit includes a first power unit 21 installed on the bracket 1 and a limb fixation part 22 hoisted on the first power unit 21 and used to be sleeved on the patient's limb. The limb fixation part 22 is located within the training space. The first power unit 21 is used to drive the limb fixation part 22 to lift and lower after operation. Among them, before the patient is transferred into the training space, the limb fixation part 22 can be located at the top of the training space and higher than the patient's head through the first power unit 21, so as to avoid the limb fixation part 22 affecting the patient's movement. After the patient moves into the training space, the first power unit 21 drives the limb fixation part 22 to descend to a position at the same height as the patient's upper body. After the limb fixation part 22 is worn on the patient's upper body by the attendant beside, the first power unit 21 can drive the limb fixation part 22 to rise to a certain extent to ensure that the patient's lower limbs can use the leg training unit in a standing or sitting manner, so that the patient can have sufficient energy to train the lower limbs and reduce the labor intensity of the patient's upper body. It should be noted that the limb fixation unit is not limited to the structure of this embodiment, and other devices capable of fixing the patient's upper body can also be used for replacement. In another embodiment, the limb fixation unit includes a swing arm with one end hinged on the top of the bracket 1 made of a rigid material and a third protective belt fixedly installed on the swing arm. The third protective belt includes a third loop belt for surrounding the patient's chest for one week and two second shoulder straps with both ends fixedly connected to the third loop belt respectively. The front ends of the two second shoulder straps are spaced apart and the rear ends are cross-distributed for sleeving on the patient's two shoulders. One side where the two second shoulder straps cross and the corresponding side of the third loop belt are both fixedly connected to the swing arm. The swing arm can be automatically controlled by setting a power device for driving its rotation, so as to cooperate with the third protective belt to support the patient's upper body.

[0030] In the content defined by this embodiment, the limb fixing part 22 includes a first protective belt 221 hoisted on the first power part 21 and a second protective belt 222 hoisted on the first power part 21. Among them, a first connecting belt 223 is connected to both sides of the first protective belt 221, and the top end of the first connecting belt 223 is connected to the first power part 21, and the first protective belt 221 is used to be worn on the upper body of the patient; a second connecting belt 224 is connected to both sides of the second protective belt 222, and the top end of the second connecting belt 224 is connected to the first power part 21, and the second protective belt 222 is used to be worn on the patient's buttocks and the root of the thighs to support the patient's buttocks through the cooperation of the first power part 21. Correspondingly, the first power part 21 includes a first winding part 211 arranged on the bracket 1 and located at the top of the training space and two second winding parts 212 arranged on the bracket 1 and located on both sides of the training space. The first winding part 211 is connected to the two first connecting belts 223 for winding the two first connecting belts 223, and the second winding parts 212 are respectively connected to the two second connecting belts 224 for winding the second connecting belts 224. The first power part 21 realizes the lifting of the first protective belt 221 and the second protective belt 222 by respectively winding or unwinding the first connecting belt 223 and the second connecting belt 224 through the first winding part 211 and the second winding part 212. Among them, the first winding part 211 and the second winding part 212 operate independently. Therefore, the lifting of the first protective belt 221 and the second protective belt 222 is also carried out independently, so as to be used by patients with different upper body conditions and support the upper body of the patient in a comfortable state as much as possible.

[0031] In this embodiment, the first protective belt 221 includes a first annular belt 2211 and two shoulder straps 2212 with both ends fixedly connected to the first annular belt 2211 respectively. Among them, the front ends of the two shoulder straps 2212 (both refer to the sides where the shoulder straps 2212 face away from the moving inclined plane 14 along the longitudinal direction) are spaced apart, and the rear ends of the two shoulder straps 2212 are cross - distributed for sleeving on the two shoulders of the patient. The two shoulders and arms of the patient pass through the inner sides of the two shoulder straps 2212 respectively in a back - to - back manner. Both the first annular belt 2211 and the shoulder straps 2212 are made of strip - shaped nylon belts. Insert buckles 2213 and locking buckles 2214 are respectively arranged at both ends of the first annular belt 2211. The insert buckles 2213 and the locking buckles 2214 are any existing detachable protective buckles 2214, and the detachable connection is achieved through an insertion and engagement method, so as to facilitate the first protective belt 221 to be worn on the upper body of the patient, and the upper body is lifted through the cooperation between the first annular belt 2211 and the upper limbs of the patient. Regarding the specific structures of the insert buckles 2213 and the locking buckles 2214, since they are prior art, they will not be elaborated here. At the part where the two shoulder straps 2212 cross at the rear end, a metal fixing piece for respectively fixing the crossed part can be provided. Through holes for the two shoulder straps 2212 to pass through are opened on the metal fixing piece so that it always remains in a crossed state. The first connecting belt 223 is a strip - shaped nylon belt. The middle part thereof bypasses the hole of the metal fixing piece, and both ends are spaced apart and fixedly connected to the first winding part 211, so that the first connecting belt 223 forms a triangular shape and can hoist the first protective belt 221 relatively stably.

[0032] Corresponding to the first protective belt 221, the first winding part 211 includes a first driving member 2111 and a first roller 2112 axially connected to the output shaft of the first driving member 2111. First through - holes are correspondingly opened on the two cross - frames 13 distributed along the transverse direction. A bearing is fixedly arranged in each first through - hole. Both ends of the first roller 2112 are respectively fixedly connected to the inner ring surfaces of the bearings in the two first through - holes, so that the first roller 2112 can rotate self - sufficiently. Among them, the first roller 2112 is located at the top central position of the training space, and the first driving member 2111 is fixedly connected to the outside of one of the cross - frames 13 provided with the first through - hole, and its output shaft is fixedly and coaxially connected to the first roller 2112. The first driving member 2111 can be a motor capable of forward and reverse rotation. In order to prevent the motor from rotating too fast, a corresponding speed reducer can be arranged on the output shaft of the motor, or a low - speed motor can be directly selected. Both ends of the first connecting belt 223 are fixedly connected to the first roller 2112. When the first roller 2112 rotates forward under the drive of the first driving member 2111, the first connecting belt 223 is wound on the first roller 2112, and the first protective belt 221 moves upward. On the contrary, when the first roller 2112 rotates reversely under the drive of the first driving member 2111, the first connecting belt 223 unfolds from the wound state, and the second protective belt 222 moves downward.

[0033] In this embodiment, the second protective belt 222 includes a second annular belt 2221 and two supporting belts 2222 with both ends respectively connected to the second annular belt 2221. The second annular belt 2221 and the first annular belt 2211 are arranged in the same way and are both made of strip-shaped nylon belts provided with protective buckles 2214. The two supporting belts 2222 are also supported by strip-shaped nylon belts, and the two supporting belts 2222 are horizontally arranged on both sides of the second annular belt 2221. The middle parts of the two supporting belts 2222 are fixedly connected to each other so that a space for the patient's legs to pass through is defined between the two supporting belts 2222 and the second annular belt 2221. The patient passes the two legs through the inner sides of the two supporting belts 2222 until the supporting belts 2222 respectively hold the root of the patient's thighs and support the patient's buttocks.

[0034] Corresponding to the second protective belt 222, the length directions of the two second winding parts 212 are both distributed longitudinally, and the two second winding parts 212 are respectively horizontally arranged on both sides of the bracket 1. Among them, second through holes are coaxially formed longitudinally on the two vertical frames 12 horizontally arranged on one side, and second through holes are also formed longitudinally on the other two vertical frames 12, and each second through hole is located at the same height. Bearings are fixedly connected in each second through hole. Each of the two second winding parts 212 includes a second roller 2121 with a length direction distributed longitudinally. The two ends of one second roller 2121 are respectively fixedly connected to the bearings in the second through holes on the two vertical frames 12 horizontally arranged on the same side, and the two ends of the other second roller 2121 are respectively fixedly connected to the bearings in the other two second through holes, so that both second rollers 2121 can rotate. One of the second winding parts 212 also has a second driving member 2122 fixedly installed on the vertical frame 12 and coaxially fixedly connected to the second roller 2121 of the corresponding second winding part 212. The second driving member 2122 is the same as the first driving member 2111 and can be a motor capable of forward and reverse rotation. The second driving member 2122 is used to drive the corresponding second roller 2121 to rotate forward and backward. The second connecting belt 224 can be the same as the first connecting belt 223 and forms a triangular shape by folding in the middle. In this embodiment, two second connecting belts 224 are arranged on both sides of the second protective belt 222. The two second connecting belts 224 are spaced apart and symmetrically arranged. One end of each second connecting belt 224 is fixedly connected to the second annular belt 2221, and the other ends of each second connecting belt 224 are fixedly and spacedly connected to the two second rollers 2121 in pairs, and the second connecting belts 224 do not cross each other. And relative to the first connecting belt 223, the second connecting belts 224 on both sides of the second protective belt 222 are located on both sides of the first connecting belt 223 to avoid interfering with each other and affecting the use.

[0035] In order to ensure the retracting effect of the second protective belt 222, the two second rollers 2121 of the two second retracting parts 212 are connected in transmission to rotate synchronously. Among them, the limb fixing part 22 also includes a transmission part 225, and the ends of the two second rollers 2121 facing the same side are both passed out of the second through hole. The transmission part 225 includes two first transmission wheels 2251 that are respectively fixed and coaxially sleeved on the ends of the two second rollers 2121 passing out of the second through hole, and a first transmission belt 2252 wound around the two first transmission wheels 2251. The two first transmission wheels 2251 are usually gears, and the first transmission belt 2252 is a toothed belt for meshing with the first transmission wheels 2251. A protective cover 2253 is fixedly connected to the vertical frame 12 to cover the outer ends of the two second rollers 2121 passing through the second through holes. The first transmission wheel 2251 and the first transmission belt 2252 are both located in the protective cover 2253 to prevent the first transmission belt 2252 and the first transmission wheel 2251 from getting entangled with other structures or human bodies.

[0036] See also Figures 1 to 5 In this embodiment, the leg training unit includes a first leg training unit 31 movably mounted at the bottom of the training space, a second leg training unit 32 movably mounted at the bottom of the training space, and a position switching structure 33 for switching the positions of the first leg training unit 31 and the second leg training unit 32 in the training space. The first leg training unit 31 is used to drive the patient's legs to perform free cycling training by pedaling and swinging in a dislocated manner, thereby exercising the patient's leg, buttocks, waist and abdominal muscles, and also has a training effect on the joints; the second leg training unit 32 is used to assist the patient to step on the spot to walk, thereby exercising the patient's autonomous walking, and is used to train the patient to perform autonomous leg force training; the position switching structure 33 can change the position of the first leg training unit 31 and the second leg training unit 32, so as to move the first leg training unit 31 or the second leg training unit 32 to the bottom of the limb fixing unit according to the actual training situation, so as to perform appropriate training. In another embodiment, the leg training unit may only include the first leg training part 31 or the second leg training part 32 to be used as a dedicated auxiliary training setting with a single function, or a secondary frame may be provided on the front side of the bracket 1, and the leg training unit also includes a turntable rotatably mounted on the secondary frame and two gripping rods coaxially connected on both sides of the turntable, and the two gripping rods are rotatably connected to the turntable through bearings so as to be able to rotate by themselves, and the patient's hands respectively hold the two gripping rods and shake them manually to achieve arm muscle exercise. Among them, the turntable can also be rotated by using a power device such as rotatably connecting the secondary frame to the bracket 1 and connecting it to a motor fixedly connected to the bracket 1. The turntable can be fixedly connected to the secondary frame so as to drive the turntable to rotate through the motor, so that after the patient's hands hold the gripping rods, the patient's arms are driven to swing and bend with the rotation of the turntable.

[0037] In the content defined in this embodiment, the first leg training part 31 includes a first base 311 movably installed at the bottom of the training space, a base 312 installed on the top of the first base 311, and two pedals 313 rotatably installed on both sides of the base 312. The first base 311 is used to cooperate with the cutting structure 33 to switch positions and support the base 312. The base 312 provides support for the pedal 313 so that the patient's legs can contact the pedal 313. The pedal 313 is used for the patient to step on it with his feet in a staggered manner. The patient can achieve leg training by stepping on the pedal 313 alternately with his feet in opposite directions.

[0038] In another embodiment, in order to facilitate the training of patients with movement disorders with weak leg strength, the first leg training unit 31 also includes a second power unit 314 arranged in the base 312 and connected to the pedal 313 by transmission, so that the two pedals 313 are driven to rotate through the second power unit 314 to drive the patient's two feet to swing alternately. In this embodiment, the first base 311 is a rectangular parallelepiped structure and the length, width and height are all corresponding to the length and width of the bottom plate 11. The first base 311 can be made of solid materials with low density, such as wood, to ensure that the base 312 is sufficiently supported while the weight is arranged so as not to be too heavy and affect movement. The base 312 is made of alloy and has a hollow internal cavity inside. The base 312 is a structure with a narrow top and a wide bottom, and the two side surfaces of the base 312 along the horizontal direction are parallel planes, so that the patient's legs can be extended outside the two sides of the base 312 along the horizontal direction. A first slide groove 3111 is vertically provided on the top surface of the first base 311. The first slide groove 3111 is convex-shaped, and the upward portion is a narrow portion, and the downward portion is a wide portion. The first slide groove 3111 is extended longitudinally and penetrates the first base 311 on the side away from the moving inclined surface 14. The bottom surface of the base 312 is a horizontal plane parallel to the top surface of the first base 311, and the bottom surface width of the base 312 is greater than the top width of the first slide groove 3111. A convex slider adapted to the first slide groove 3111 is convexly provided on the bottom surface of the base 312. The first slide groove 3111 penetrates one end of the first base 311 to facilitate the slider to enter therein, so that the base 312 is slidably arranged on the first base 311 along the longitudinal direction. A fixed block 3112 is fixedly connected to the top surface of the end of the first base 311 away from the moving inclined surface 14 to block the first slide groove 3111. In order to prevent the base 312 from excessively sliding during use, the lower half of the base 312 is a solid structure to increase the weight of the base 312 and increase the friction between the base 312 and the first base 311 through its gravity.

[0039] In the content defined in this embodiment, a protrusion is formed by protruding upward from the top of the base 312. A third through hole is transversely formed in the protrusion, and a bearing is fixedly connected in the third through hole. Each of the two pedals 313 includes a connecting rod 3131 and a foot pedal 3132 that is rotatably connected to one end of the connecting rod 3131 and extends away from the base 312 relative to the connecting rod 3131. Among them, the ends of the two connecting rods 3131 away from the foot pedal 3132 are bent in an arc shape toward the base 312. A rotating shaft is fixedly connected to the inner ring of the bearing in the third through hole, and the arc-shaped ends of the two connecting rods 3131 are fixedly connected to both ends of the rotating shaft in parallel and opposite directions. Among them, the end of the connecting rod 3131 provided with the foot pedal 3132 is bent in an arc shape toward the side away from the base 312. A bearing is fixedly connected to the side of the two foot pedals 313 facing the base 312, and the end of the connecting rod 3131 away from the rotating shaft is connected to the inner ring of the bearing on the corresponding foot pedal 3132, so that the foot pedal 3132 can rotate relative to the connecting rod 3131. In order to prevent the patient's sole from slipping after stepping on the foot pedal 3132, shoe supports 3133 into which the patient's toes or shoe tips can be inserted are provided on the front sides of the tops of the two pedals 313. The shoe supports 3133 are in an arc-shaped crescent shape, and the edges are fixedly connected to the edges of the corresponding foot pedals 3132.

[0040] In the content defined in this embodiment, the second leg training unit 32 includes a second base 321 movably installed at the bottom of the training space and a stepper 322 disposed on the second base 321. Among them, the heights of the stepper 322, the first base 311, the second base 321, and the bottom surface of the training space are all the same, so as to facilitate the wheelchair to be transferred to the bottom of the training space. In this embodiment, the length, width, and height of the second base 321 are all the same as those of the first base 311, and the inside of the second base 321 is hollow and vertically penetrates up and down to form a frame shape. The stepper 322 includes a plurality of third rollers rotatably connected to the inner side of the second base 321 through bearings, second transmission wheels fixedly sleeved on each third roller, a second transmission belt wound around each second transmission wheel, a drive motor fixedly installed on the second base 321 and fixedly connected to one of the third rollers, and a walking transmission belt wound around each third roller. The height of the walking transmission belt is the same as the top surface height of the second base 321. Among them, each third roller is longitudinally arranged in parallel at equal intervals, and the interval should be as small as possible. The axial directions of all the third rollers are arranged transversely. The structures and cooperation methods between the second transmission wheels and the second transmission belt and the first transmission wheels 2251 and the first transmission belt 2252 are the same, and will not be elaborated here. The walking transmission belt and the third roller can also be the same, and the specific principle structure can refer to the structure of the treadmill. When in use, after moving the second leg training unit 32 under the limb fixing unit, when the drive motor is started, the walking transmission belt at the top moves longitudinally toward the side close to the moving inclined surface 14, so that patients with less severe leg disabilities can walk in place to exercise leg muscles, and the moving speed of the walking transmission belt is adjustable.

[0041] In the content defined by this embodiment, the cutting position structure 33 includes a bottom groove 331 recessed from the bottom surface of the training space, at least two slide rails 332 arranged on the bottom wall of the bottom groove 331 along a transverse direction perpendicular to the longitudinal direction, and a compensation plate 333. In this embodiment, the bottom groove 331 has a cuboid cavity structure, and the length and width of the compensation plate 333 correspond to the length and width of the first base 311. The length of the bottom groove 331 corresponds to the sum of the lengths of the first base 311, the second base 321, and the compensation plate 333, and the width of the bottom groove 331 corresponds to the widths of the first base 311, the second base 321, and the compensation plate 333, so that the second base 321, the first base 311, and the compensation plate 333 can be placed adjacent to each other in sequence along the transverse direction in the bottom groove 331, and it is ensured that the gaps between the first base 311, the second base 321, and the compensation plate 333 and the inner side walls of the bottom groove 331 are relatively small, such as within 2 cm. In this embodiment, three slide rails 332 are provided and evenly distributed on the bottom wall of the bottom groove 331. The cross-section of the slide rail 332 can be rectangular or triangular with a narrow top, so as to facilitate the second chute to be mounted on the slide rail 332 vertically, but it is not limited to the foregoing cross-sectional shapes. Second chutes penetrating transversely are provided at the positions corresponding to the three slide rails 332 on the bottom surfaces of the first base 311 and the second base 321. The first base 311 and the second base 321 are slidably supported on the slide rails 332 through the second chutes, so that the first base 311 and the second base 321 are both slidably arranged in the bottom groove 331 along the longitudinal direction through the slide rails 332. The thickness of the compensation plate 333 is equal to the vertical distance between the top surface of the slide rail 332 and the top of the bottom groove 331, and the bottom surface of the compensation plate 333 is directly in contact with the top surface of the slide rail 332 and placed in the bottom groove 331, so that the compensation plate 333 can move longitudinally and transversely. Openings 334 for the compensation plate 333 to pass through are longitudinally provided on one side of the bottom groove 331 corresponding to the second base 321 and the compensation plate 333 along the longitudinal direction. The openings 334 enable the compensation plate 333 to move longitudinally out of the bottom groove 331. For the convenience of moving the compensation plate 333, first guiding inclined surfaces 3331 are provided at both ends of the compensation plate 333, and the two first guiding inclined surfaces 3331 make the compensation plate 333 have an isosceles trapezoid structure with a narrow bottom. Second guiding inclined surfaces 3341 are provided on the bottom surfaces of the respective openings 334. The second guiding inclined surfaces 3341 are inclined downward on the side away from the bottom groove 331 and are flush with the ground, so as to facilitate moving the compensation plate 333 in a pushing or pulling manner longitudinally.When in use, when the first leg training part 31 needs to be used, the compensation plate 333 and the second leg training part 32 are distributed transversely on both sides of the first leg training part 31. The first base 311, the second base 321 and the compensation plate 333 are convenient for filling the top surface of the bottom plate 11 to avoid the situation that the wheelchair or the feet of a person sink. When the second leg training part 32 needs to be used, the compensation plate 333 is pulled out longitudinally, the first leg training part 31 is moved towards the original position of the compensation plate 333, and then the second leg training part 32 is moved directly below the limb fixing unit, and the compensation plate 333 is pushed to the original position of the second leg training part 32, so that the position can be switched and the bottom plate 11 can be filled. In order to facilitate the pushing and pulling of the compensation plate 333, a handle can be fixedly connected to the second wire slope on the side of the compensation plate 333 away from the moving slope 14. The compensation plate 333 is made of a light material, such as plastic, wood, etc.

[0042] In order to facilitate the arrangement of the driving motor, a receiving groove 15 can be opened on the bottom wall of the bottom groove 331. The receiving groove 15 extends transversely. The driving motor can extend into the receiving groove 15 by arranging a speed reducer and other devices on the second base 321, so that it can move with the movement of the second base 321. The circuits of each power device can be ensured that the movement of the first base 311 and the second base 321 will not affect the use of the circuit by arranging a drag chain and other structures in the bottom groove 331.

[0043] Please refer to Figure 1 and Figure 7 , in this embodiment, receiving grooves 15 are opened on both vertical frames 12 of the bracket 1 located on the front side (the front side refers to the side relative to the bracket 1 along the longitudinal direction away from the moving slope 14). The two receiving grooves 15 are open on the side facing each other and the length direction is distributed vertically. The top end of the receiving groove 15 is basically at the same height as the first protective belt 221. One ends of the two armrest parts 42 are respectively rotatably connected in the two receiving grooves 15 through hinge chains or universal ball joints, and the length of the receiving groove 15 is adapted to the length of the handrail part 4 and is slightly longer than the length of the handrail part 4, so that the handrail part 4 can be received in the receiving groove 15.

[0044] In the content defined by this embodiment, the bottom ends of the two hand-holding parts 4 both have free ends that can swing freely. The two free sections are detachably connected and are located on the side of the limb fixing part 22 when connected. Each hand-holding part 4 includes a support rod 41 with one end hinged inside the top end of the receiving groove 15 and a handrail 42 fixedly connected to the support rod 41. The free ends of the two support rods 41 are at the non-hinged ends. A connecting cylinder 43 is connected to the free end of one of the support rods 41, a support ring plate 44 fixedly connected to the side of the connecting cylinder 43 away from the other support rod 41, and a spring 45 located between the support ring plate 44 and the connecting cylinder 43. Among them, the connecting cylinder 43 is slidably connected to the support rod 41 on which it is located along its axial direction. A threaded hole with an opening facing the other support rod 41 is provided inside the connecting cylinder 43, and the end of the support rod 41 where the connecting cylinder 43 is located slides into the threaded hole. A fourth through hole with a size smaller than the threaded hole and adapted to the support rod 41 is provided on the end face of the connecting cylinder 43 close to the support rod 41. The end of the support rod 41 is cylindrical and after passing through the similarly cylindrical fourth through hole, a limiting edge that cannot pass through the fourth through hole extends radially on the end face where it penetrates into the threaded hole. The connecting cylinder 43 can rotate relative to the support rod 41, and the spring 45 presses against the connecting cylinder 43 towards the side away from the support ring plate 44. A threaded post 46 adapted to the threaded hole is fixedly connected to the free end of the other support rod 41. When in use, when the two support rods 41 are rotated out of the receiving groove 15 and rotated towards each other until they are coaxial, the threaded hole presses against the connecting cylinder 43 towards the side of the support ring plate 44. At this time, the connecting cylinder 43 is squeezed and moves towards the side away from the threaded post 46. At this time, by rotating the connecting cylinder 43, the connecting cylinder 43 can be screwed onto the threaded post 46 to achieve connection. When it needs to be removed, just rotate it in the reverse direction. One ends of the two handrails 42 extend in a direction perpendicular to the support rod 41, and the other ends of the two handrails 42 bend towards the training space side and then extend. In another embodiment, a moving block can be connected to the receiving groove 15 by means of bolts. After removing the bolts, the moving block can slide vertically in the receiving cavity. Threaded holes can be provided vertically on the inner wall of the receiving cavity, and threaded holes are also provided on the moving block, so that the height of the hand-holding part 4 can be adjusted.

[0045] In this embodiment, a control box 5 is provided on the bracket 1. Devices such as a controller and a power supply are provided inside the control box 5. Various adjustment buttons electrically connected to the controller and the power supply are provided on the control box 5. The first driving member 2111, the second driving member 2122, the driving motor, and each motor are all electrically connected to the power supply and the controller. By using the adjustment buttons, the controller controls the opening and closing and start modes of each power device.

[0046] One working mode of the auxiliary training device for patients with movement disorders according to the present invention is as follows: In the initial state, the base 312 slides relative to the first base 311 to the side away from the moving inclined plane 14, and the hand-held part 4 is received in the receiving groove 15. First, move the first leg training part 31 or the second leg training part 32 to be used to the middle position and place the compensation plate 333. Then, move the patient into the training space. For patients using a wheelchair, first, lower the first protective belt 221 through the first driving member 2111, put on the first protective belt 221 on the upper body of the patient, let the patient's arm pass through the shoulder strap 2212, and after the first loop belt 2211 is looped around the chest and the lock 2214 is fastened, lower the second protective belt 222 so that the patient's feet and calves pass through the two support belts 2222. Then, make the first driving member 2111 reel in the first connecting belt 223 to move the first protective belt 221 upward. After the patient's buttocks leave the wheelchair, move the wheelchair away and move the support belt 2222 to the patient's thighs to support the buttocks. Then, the second driving member 2122 operates to drive the second protective belt 222 upward until the patient's soles can contact the walking protective belt or the footrest 3132 in a proper form. After the first protective belt 221 is adjusted to a comfortable position manually, both the first driving member 2111 and the second driving member 2122 are turned off. Connect the hand-held part 4 together through the threaded column 46 and the connecting cylinder 43 as needed, so that the patient holds the handrail 42. Then, start the first leg training part 31 or the second leg training part 32 to perform leg training.

[0047] Compared with the prior art, the auxiliary training device for patients with movement disorders according to the present invention not only realizes the switching of the exercise mode, but also reduces the leg burden of the patient by supporting the upper body, and improves the stability during exercise through the hand-held part 4, so as to be able to perform more adaptable leg training for different patients.
