Description

Technical Field

[0001] The present invention relates to the technical field of medical rehabilitation equipment, and in particular to a balance training device. Background Art

[0002] Cerebral infarction and other diseases can cause damage to brain tissues such as the cerebellum, basal ganglia or brainstem, affecting the motor control area and causing motor coordination disorders, which are mainly manifested in symptoms such as uncoordinated limb movements, decreased balance ability, and unstable gait. For this type of balance dysfunction, modern medical rehabilitation centers adopt a rehabilitation model that allows patients to stand on a swinging platform. Through the multi-directional movement of the platform, patients are forced to use different muscles to stand firmly on the platform. However, with existing balance training devices, patients can only be trained in situ. The training model is single and focuses more on training the patient's muscle strength. It cannot specifically simulate the patient's training in a walking state, resulting in unsatisfactory balance rehabilitation training results. Summary of the Invention

[0003] The purpose of the present invention is to provide a balance training device to solve the problem that the existing balance training device has a single training action and cannot specifically simulate the training of patients in a walking state, resulting in unsatisfactory rehabilitation training effects.

[0004] To achieve the above object, the basic scheme of the present invention is as follows:

[0005] A balance training device includes a horizontally arranged base plate, a walking board group arranged on the base plate for a patient to walk, and a support member for supporting the patient. The walking board group is movably connected to the base plate, and the inclination angle of the walking board group can be adjusted to change the difficulty of the patient's walking. The support member is used to prevent the patient from falling during movement.

[0006] Furthermore, the walking plate group includes a support seat arranged near a long side of the base plate and along the length direction of the base plate, a plurality of independent plates arranged in sequence along the length direction of the base plate, and a plurality of telescopic parts arranged corresponding to the independent plates. One end of the independent plate is rotatably connected to the support seat through a rotating shaft 1 horizontally arranged along the length direction of the base plate, and the end of the independent plate away from the support seat is a free end. The telescopic part is arranged below the free end of the independent plate, the lower end of the telescopic part is connected to the base plate, and the upper end of the telescopic part contacts the independent plate. The telescopic part can be extended and retracted to force the independent plate to rotate a certain angle around the rotating shaft 1 so that the independent plate is in a certain inclined state.

[0007] Furthermore, the supporting member includes support columns vertically arranged at the four corners of the base plate and handrails horizontally arranged along the length direction of the base plate and detachably connected to the support columns.

[0008] Furthermore, the support member also includes a longitudinal rod horizontally arranged along the length direction of the base plate and a transverse rod horizontally arranged along the width direction of the base plate, the longitudinal rod is fixedly connected to the upper end of the support column, and the transverse rod and the longitudinal rod are both provided with a sliding sleeve, and the sliding sleeve is slidably connected to the corresponding longitudinal rod or transverse rod, and the two ends of the transverse rod are respectively fixedly connected to the sliding sleeve on one of the longitudinal rods, and a flexible safety strap is provided on the sliding sleeve on the transverse rod, the upper end of the safety strap is fixedly connected to the corresponding sliding sleeve, and the lower end of the safety strap is a free end.

[0009] The top end of the gear train is fixedly mounted on the drive means, and the bottom end of the gear train is engaged with the gear of the control wheel, and the bottom end of the gear train is engaged with the gear of the control wheel.

[0010] Furthermore, the baffle is provided with limit grooves on both sides of the first rotation direction and the second rotation direction of the rotating shaft 2. When the baffle contacts the baffle block to stop the rotation of the rotating shaft 2, the baffle block is located in the limit groove to prevent the baffle from sliding toward the axial direction of the rotating shaft 2.

[0011] Furthermore, connecting rod 1 and connecting rod 2 are provided at both ends of the handrail rod, and multiple sockets are arranged vertically on the support column. The sockets are along the length direction of the base plate. The first ends of connecting rod 1 and connecting rod 2 are rotatably connected to the handrail rod, and the first ends of connecting rod 1 and connecting rod 2 are connected to the sockets through the plug rod.

[0012] Furthermore, the telescopic member includes a vertically arranged electric cylinder, the lower end of the electric cylinder is fixedly connected to the base plate, and the output shaft of the electric cylinder contacts the lower surface of the corresponding independent plate.

[0013] Furthermore, the longitudinal rod and the transverse rod are both rectangular rods, and the rack is arranged on the lower surfaces of the longitudinal rod and the transverse rod.

[0014] Furthermore, the through slot passes through the slide downward, and the lower end of the slide is detachably connected to a bottom plate that closes the lower end of the through slot, and the upper end of the safety strap is fixedly connected to the bottom plate.

[0015] Compared with the prior art where patients can only train in situ, the present invention has at least the following beneficial effects:

[0016] 1. In this solution, each electric cylinder can be controlled to make each independent plate in a horizontal state to form a horizontal walking platform. It can be used for patients to simulate walking training on flat ground. Patients can hold the handrails to control their body balance while walking to prevent falling. It can be used for patients' initial walking training.

[0017] 2. In this solution, each electric cylinder can be controlled so that each independent plate is in the same tilt state to form an inclined walking platform, which can be used for patients to simulate walking training on an inclined ground.

[0018] 3. In this solution, different independent plates can be placed in different tilt states by controlling different electric cylinders to simulate uneven ground, which can be used for patients to simulate walking training on uneven ground.

[0019] 4. In this solution, the height of the handrail and the distance between the handrail and the support column can be changed by matching the insertion rod with the sockets in different positions to meet the needs of patients with different body shapes.

[0020] 5. In this solution, the handrail can be removed and the lower end of the safety belt can be tied to the patient's chest, so that the patient can swing his hands freely and walk freely on the walking platform composed of independent boards. When the patient is trained normally and can walk slowly, the safety belt moves with the patient. Under the pull of the safety belt, each slide slides freely on the corresponding transverse rod or longitudinal rod. The sliding of the slide causes the corresponding gear to rotate and drives the rotating shaft 2 to rotate. Under the elastic force of the tension spring, the centrifugal force generated by the rotation of the rotating shaft 2 when the patient walks normally is not enough to make the stop bar slide to contact with the stop block, and the patient can walk freely. However, when the patient suddenly falls in a certain direction due to inability to maintain balance, the safety belt quickly pulls the slide to slide quickly, causing the corresponding gear to suddenly speed up and then rotate. The speed of shaft two is accelerated synchronously, which increases the centrifugal force on the stop rod and causes the stop rod to slide until it contacts a certain block. When the stop rod contacts the block, the block blocks the stop rod, causing shaft two to stop rotating, and then the gear also stops rotating, causing the slide to stop sliding to prevent the patient from further tipping over and falling. When the stop rod contacts the block, causing shaft two to stop rotating, the block is located in the limit groove on the stop rod. At this time, the tension spring cannot force the stop rod to slide in the direction close to the axis of shaft two. The stop rod always remains in contact with the block to prevent the slide from continuing to slide. After the patient strives to restore his balance, the patient or other personnel pulls the safety strap in the opposite direction of the tipping direction to reverse the gear, causing the stop rod to slide out of the block under the elastic force of the tension spring, and the patient can then continue to perform independent walking training.

[0038] Combine Figure 1-Figure 3As shown, the base plate 10 is a rectangular plate, and the walking plate group includes a support seat 40 arranged near one long side of the base plate 10 and along the length direction of the base plate 10, a plurality of independent plates 41 arranged in sequence along the length direction of the base plate 10, and a plurality of telescopic members arranged corresponding to the independent plates 41. The support seat 40 is fixedly connected to the base plate 10, and the independent plate 41 is a rectangular plate and is arranged along the width direction of the base plate 10. One end of the independent plate 41 is rotatably connected to the support seat 40 through a rotating shaft 42 horizontally arranged along the length direction of the base plate 10. The end of the vertical plate 41 away from the support seat 40 is a free end, and the telescopic part is an electric cylinder 43. The electric cylinder 43 is connected to an external power supply and a controller for controlling the operation of the electric cylinder 43. The electric cylinder 43 is arranged below the free end of the independent plate 41, and the lower end of the electric cylinder 43 is fixedly connected to the base plate 10. The output shaft of the electric cylinder 43 is arranged vertically upward and contacts with the lower surface of the corresponding independent plate 41. The output shaft of the electric cylinder 43 can be controlled to extend or shorten to force the corresponding independent plate 41 to rotate a certain angle around the rotating shaft 42 so that the independent plate 41 is in a certain tilted state.

[0039] The support member includes support columns 21 vertically arranged at the four corners of the base plate 10, longitudinal rods 23 horizontally arranged along the length direction of the base plate 10, transverse rods 24 horizontally arranged along the width direction of the base plate 10, and handrails 22 horizontally arranged along the length direction of the base plate 10 and detachably connected to the support columns 21. The support column 21 is vertically arranged, and the lower end of the support column 21 is fixedly connected to the base plate 10. The longitudinal rods 23 and the transverse rods 24 are both rectangular rods. Figure 4-Figure 6 As shown, the lower surfaces of the longitudinal rod 23 and the transverse rod 24 are fixedly connected with a rack 32, the rack 32 on the longitudinal rod 23 is arranged along the length direction of the base plate 10, and the rack 32 on the transverse rod 24 is arranged along the width direction of the base plate 10, the two ends of the longitudinal rod 23 are respectively fixedly connected to the upper end of one of the support columns 21, and the transverse rod 24 and the longitudinal rod 23 are both sleeved with a sliding sleeve 30, the sliding sleeve 30 is slidably connected to the corresponding longitudinal rod 23 or transverse rod 24, and the sliding sleeve 30 includes a slide 301 sleeved on the corresponding longitudinal rod 23 or transverse rod 24 and a gear 302 arranged in the slide 301 and meshing with the rack 32, one end of the transverse rod 24 is fixedly connected to the slide 301 on one of the longitudinal rods 23, and the other end of the transverse rod 24 is fixedly connected to the slide 301 on the other longitudinal rod 23.

[0040] A through slot 303 is provided at the lower end of the slide 301 along the length direction of the rack 32, and the through slot 303 passes through the slide 301 downwardly. The lower end of the slide 301 is connected to a bottom plate 308 that closes the lower end of the through slot 303 by bolts. A flexible safety strap 31 is provided on the bottom plate 308 on the transverse rod 24, and the upper end of the safety strap 31 is fixedly connected to the bottom plate 308 on the slide 301, and the lower end of the safety strap 31 is a free end. The rack 32 is located in the through slot 303 and is fixedly connected to the transverse rod 24 or the longitudinal rod 23. The gear 302 is arranged in the through slot 303. The gear 302 is coaxially fixedly connected to the second rotating shaft 304. The second rotating shaft 304 is horizontally arranged along the width direction of the base. The second rotating shaft 304 is rotatably connected to the slide 301. Both ends of the second rotating shaft 304 extend out of the slide 301. A slideway 3041 is provided on the second rotating shaft 304 located outside the slide 301 along the radial direction of the second rotating shaft 304. One end of the slideway 3041 passes through the second rotating shaft 304, and the other end of the slideway 3041 is a blind end. A blocking rod 305 and a tension spring 306 are provided in the slideway 3041. The blocking rod 305 is connected to the second rotating shaft 304. The slide 3041 is slidably connected, one end of the tension spring 306 is fixedly connected to the baffle rod 305, and the other end of the tension spring 306 is fixedly connected to the blind end of the slide 3041. When the second rotating shaft 304 is in a stationary state, the center of mass of the baffle rod 305 is eccentrically arranged with respect to the axis of the second rotating shaft 304. Specifically, the center of mass of the baffle rod 305 is located in the area between the axis of the second rotating shaft 304 and the opening of the slide 3041. When the second rotating shaft 304 rotates, the baffle rod 305 slides in the direction away from the axis of the second rotating shaft 304 under the action of centrifugal force and extends the baffle rod 305 out of the second rotating shaft 304. The faster the rotation speed of the second rotating shaft 304, the longer the part of the baffle rod 305 extending out of the second rotating shaft 304. A plurality of stops 307 are evenly distributed in a ring around the second rotating shaft 304 on the outer wall of the slide 301, and the stops 307 are fixedly connected to the slide 301. In this embodiment, six stops 307 are evenly distributed in a ring on the outer wall of the slide 301. In other embodiments, other numbers of stops 307 can be reasonably set, which will not be listed one by one here.

[0041] Limiting grooves 3051 are provided on both sides of the first rotation direction and the second rotation direction of the second rotating shaft 304 at one end of the blocking rod 305 close to the blocking block 307. When the blocking rod 305 contacts the blocking block 307 to stop the rotation of the second rotating shaft 304, the blocking block 307 is located in the limiting groove 3051, preventing the blocking rod 305 from sliding out of the blocking block 307 in the axial direction close to the second rotating shaft 304 under the elastic force of the tension spring 306 when the second rotating shaft 304 is blocked and is at rest.

[0042] Both ends of the handrail rod 22 are provided with a connecting rod 1 221 and a connecting rod 2 222. A plurality of sockets 211 are vertically arranged on the support column 21. The sockets 211 are along the length direction of the base plate 10. The first ends of the connecting rod 1 221 and the connecting rod 2 222 are rotatably connected to the handrail rod 22. The first ends of the connecting rod 1 221 and the connecting rod 2 222 are connected to the sockets 211 through an insertion rod (not shown in the drawings).

[0043] Compared with the prior art in which patients can only perform activity training in situ, the present invention has at least the following beneficial effects:

[0044] 1. In this solution, each independent plate 41 can be kept in a horizontal state by controlling each electric cylinder 43 to form a horizontal walking platform, which can be used for patients to simulate walking training on flat ground. The patient can control the body balance independently while walking by holding the handrail 22 to prevent falling, which can be used for patients' initial walking training.

[0045] 2. In this solution, each electric cylinder 43 can be controlled so that each independent plate 41 is in the same tilted state to form an inclined walking platform, which can be used for patients to simulate walking training on an inclined ground.

[0046] 3. In this scheme, if Figure 7 As shown, different independent plates 41 can be placed in different tilt states to simulate rough ground by controlling the telescopic states of the output shafts of different electric cylinders 43 , which can be used for training patients to simulate walking on rough ground.

[0047] 4. In this solution, the height of the handrail rod 22 and the distance between the handrail rod 22 and the support column 21 can be changed by matching the insertion rod with the insertion hole 211 at different positions to meet the needs of patients with different body shapes.

[0048] 5. In this scheme, if Figure 7As shown, the handrail 22 can be removed and the lower end of the safety strap 31 can be tied to the patient's chest so that the patient can swing his hands freely and walk freely on the walking platform composed of the independent plates 41. When the patient is trained normally and can walk slowly, the safety strap 31 moves with the patient. Under the pull of the safety strap 31, each slide 301 slides freely on the corresponding transverse rod 24 or longitudinal rod 23. The sliding of the slide 301 causes the corresponding gear 302 to rotate and drives the second shaft 304 to rotate. Under the elastic force of the tension spring 306, the centrifugal force generated when the second shaft 304 rotates is not enough to make the blocking rod 305 slide to contact with the block 307, and the patient can walk freely. However, when the patient suddenly falls in a certain direction due to being unable to maintain balance, the safety strap 31 quickly pulls the slide 301 to slide quickly, causing the corresponding gear 302 to suddenly accelerate in speed and then the speed of the second shaft 304 to accelerate synchronously, so that the blocking rod 305 is affected When the gear 302 is in the reverse direction, the gear 302 is reversed, and the gear 302 is stopped, so that the slide 301 stops sliding to prevent the patient from falling down.

[0049] The above are only embodiments of the present invention, and the common knowledge such as the specific structure and characteristics of the scheme are not described in detail here. It should be pointed out that for those skilled in the art, without departing from the structure of the present invention, several variations and improvements can be made, which should also be regarded as the scope of protection of the present invention, and these will not affect the effect of the implementation of the present invention and the practicality of the patent. The scope of protection required by this application shall be based on the content of its claims, and the specific implementation methods and other records in the specification can be used to interpret the content of the claims.
