Description

Technical Field

[0001] This invention relates to a rehabilitation training device for patients after illness, or a fitness equipment for the elderly, particularly a balance training device for weight transfer that can adjust the pedaling force. Background Technology

[0002] Currently, with the increasing number of stroke patients, center of gravity transfer balance training devices have gradually become a necessity for stroke patient rehabilitation training. The patent application "A Flexible Center of Gravity Transfer Balance Training Device" (patent application number: 202522121299.2) includes: a center of gravity transfer mechanism, a center of gravity transfer detection device, and a center of gravity transfer display device. During use, the patient's feet move left and right on the pedals, visually monitoring their trained center of gravity transfer electronic data, and using the brain's nerves to control leg movements through the central nervous system, repeatedly training the hemiplegic leg movements to help the patient gradually recover the mobility of the hemiplegic limbs. However, the drawback of this "Flexible Center of Gravity Transfer Balance Training Device" is that the patient's feet must stand on the pedals... The force required for left and right pedal swinging is the same and cannot be adjusted. Because stroke patients often experience weakness in the paralyzed leg, it's difficult for them to swing on the pedal, hindering their rehabilitation. A flexible weight transfer balance trainer with automatically adjustable pedal force has become a necessity for doctors and trainees. Furthermore, when using an automatic flexible weight transfer balance trainer for home exercise by the elderly, a weight transfer balance trainer with adjustable pedal force is needed to accommodate the varying leg strength of different elderly individuals. Summary of the Invention

[0003] The purpose of this invention is to overcome the shortcomings of the existing technology and provide a brand-new center of gravity transfer balance training device. This device is used to adjust the left and right pedaling force of the center of gravity transfer balance training device, solve the problem that the hemiplegic patient's leg is different from the normal leg and has difficulty pedaling and swinging in a circular motion, and solve the problem that the left and right feet of the hemiplegic patient need different pedaling forces, thereby improving the training effect. At the same time, it can automatically adjust the pedaling force for elderly people with different physical conditions to suit the exercise and fitness needs of different elderly people.

[0004] The technical solution adopted in this invention is: a center of gravity transfer balance training device, comprising: The center of gravity transfer mechanism includes a housing and a foot pedal, with the foot pedal hinged to the housing via a hinge shaft; The moving mechanism includes a flexible elastic element and a traction mechanism. The flexible elastic element is connected to the traction mechanism. The flexible elastic element and the traction mechanism are installed at the bottom of the box. The flexible elastic element and the traction mechanism are located below the foot pedal. The traction mechanism is connected to the box. The traction mechanism is connected to the flexible elastic element. The flexible elastic element is dynamically connected to the bottom of the box. The controller includes a center of gravity transfer detection device and a center of gravity transfer display device, which are mounted on the foot pedal or the housing.

[0005] During use, the trainee stands on the foot pedals with both feet and swings left and right against the resistance of the flexible elastic element by pressing the pedals. The doctor or trainee can use the control traction mechanism to move the flexible elastic element to the bottom of the housing according to training needs, adjusting the distance between the flexible elastic element and the hinge axis to adjust the force required to press the pedals. When the distance between the flexible elastic element and the hinge axis increases, the force required to press the pedals increases; when the distance decreases, the force required to press the pedals decreases. This addresses the issue of hemiplegic patients requiring different pressing forces for their left and right feet, meeting the needs of different users with varying pressing forces. It also caters to the needs of elderly people with different physical conditions who require different pressing forces to swing the pedals, thus suiting the fitness and exercise requirements of different elderly individuals.

[0006] During use, the center of gravity transfer detection device detects the center of gravity transfer and pedaling force data of the foot pedal, and displays the trainee's center of gravity transfer and pedaling force data through the center of gravity transfer display device. By visually observing their own center of gravity transfer and pedaling force data, trainees can establish a connection between the brain and the limbs through the central nervous system, repeatedly train the limbs, especially hemiplegic limbs, and improve the training effect.

The pressure sensors are used to detect the gravity or pressure of the foot pedal's center of gravity transfer.

[0010] The aforementioned electrically driven flexible center of gravity transfer balance trainer has a sliding groove and a sliding seat at the bottom of the housing. The sliding seat and the sliding groove are dynamically connected, and the flexible elastic element is fixedly connected to the sliding seat. The traction mechanism includes an electric push rod, the outer shell of which is fixedly connected to the housing, and the drive rod of which is connected to the sliding seat. The axis of the electric push rod is perpendicular to the axis of the flexible elastic element, so as to realize the purpose of using the traction mechanism to drive the flexible elastic element to move, thereby adjusting the distance between the flexible elastic element and the hinge axis.

[0011] The aforementioned motor-driven flexible center of gravity transfer balance trainer has a sliding groove at the bottom of the housing, with a sliding seat movably fitted into the groove. A flexible elastic element is fixedly connected to the sliding seat. The sliding seat has a wheel, with the wheel axle movably fitted into the sliding seat. The traction mechanism includes a motor, with the motor base fixedly connected to the sliding seat and the motor shaft connected to the wheel axle. The motor drives the wheel to rotate, which in turn moves the sliding seat, and the sliding seat moves the flexible elastic element, thereby adjusting the distance between the flexible elastic element and the hinge shaft.

[0012] The traction mechanism includes a traction rod, which is movably connected to the housing via a bushing and is also connected to a slide. In use, the traction rod is used to pull the slide, causing the flexible elastic element to move and changing the distance between the flexible elastic element and the hinge axis, thereby adjusting the pedal force.

[0013] The flexible elastic element is equipped with a guide block, which is located above the pressure sensor and has a guide wheel to reduce the friction between the flexible elastic element and the foot pedal.

[0014] The aforementioned center of gravity transfer balance training device includes a foot therapy device, which includes two far-infrared therapy foot pads. The far-infrared therapy foot pads are symmetrically fixed on the left and right panels of the foot pedal. The controller is connected to the far-infrared therapy foot pads through a control line to use the far-infrared therapy foot pads to provide far-infrared therapy to the soles of the trainee's feet.

[0015] The aforementioned center of gravity transfer balance training device includes a massager mounted on a foot pedal. The foot pedal has massage holes symmetrically arranged on both sides of the foot pedal. A far-infrared therapy foot pad has acupoint holes. The massage holes and acupoint holes are on the same axis and are located above the massage holes. The massage head of the massager is located at both the massage holes and the acupoint holes. The massage head is equipped with a massage pressure sensor. A human body sensor is located next to the massager. The controller is connected to the massager and the human body sensor via a control line.

[0016] The controller is equipped with a data input interface, which includes a wired interface or a wireless interface, to connect to the Internet.

During use, the doctor or patient, based on the patient's hemiplegic condition and the different pedaling force requirements for the left and right feet, inputs center of gravity transfer training data via a touchscreen display. The controller controls the traction mechanism to move the flexible elastic element at the bottom of the housing, adjusting the distance between the flexible elastic element and the hinge axis to adjust the pedaling force. When the distance between the flexible elastic element and the hinge axis increases, the force required to pedal increases; when the distance decreases, the force required to pedal decreases. This solves the problem of hemiplegic patients requiring different pedaling forces for the left and right feet, meeting the needs of different users with different pedaling forces. It also satisfies the needs of elderly people with different physical conditions who require different pedaling forces for pedaling, thus meeting the fitness and exercise requirements of different elderly individuals.

[0021] The present invention will be further described below with reference to the accompanying drawings and specific embodiments: like Figure 1-3 As shown, a center of gravity transfer balance training device includes: The center of gravity transfer mechanism 10 includes a housing 11 and a foot pedal 12. The foot pedal 12 is hinged to the housing 11 via a hinge pin 13. In use, the trainee swings left and right by stepping on the foot pedal 12, which is hinged to the housing 12, to achieve the purpose of center of gravity transfer training. The moving mechanism 20 includes a flexible elastic element 21 and a traction mechanism 22. The flexible elastic element 21 is connected to the traction mechanism 22. The flexible elastic element 21 and the traction mechanism 22 are installed at the bottom of the housing 11 and located below the foot pedal 12. The traction mechanism 22 is connected to the housing 11 and the flexible elastic element 21. The flexible elastic element 21 is dynamically connected to the bottom of the housing 11. The flexible elastic element 21 includes a buffer, a shock absorber, and a damper. In use, the traction mechanism 22 is used to move the flexible elastic element 21 to adjust the pedaling resistance of the foot pedal 12. In use, the trainee stands on the foot pedal 12 with both feet and swings the foot pedal 12 from side to side against the resistance of the flexible elastic element. The doctor or trainee can use the control traction mechanism 20 to move the flexible elastic element 21 at the bottom of the housing 11 according to training needs, adjusting the distance between the flexible elastic element 21 and the hinge shaft 13, thus adjusting the force required to swing the foot pedal 12. When the distance between the flexible elastic element 21 and the axis of the hinge shaft 13 increases, the force required to swing the foot pedal 12 increases; when the distance decreases, the force required to swing the foot pedal 12 decreases. This addresses the issue of different pedaling forces required for the left and right feet of hemiplegic patients, meeting the needs of different users and satisfying the different physical conditions of elderly people who require different pedaling forces to swing the foot pedal 12, thus adapting to the fitness and exercise requirements of different elderly individuals.

[0022] A center of gravity transfer balance trainer includes a controller 30, which includes a center of gravity transfer detection device 31 and a center of gravity transfer display device 32. The center of gravity transfer detection device 31 and the center of gravity transfer display device 32 are mounted on the foot pedal 12 or the housing 11.

[0023] In use, the center of gravity transfer detection device 31 detects the center of gravity transfer and pedaling force data of the foot pedal 12, and displays the center of gravity transfer and pedaling force data of the trainee through the center of gravity transfer display device 32. By visually observing their own center of gravity transfer and pedaling force data, the trainee establishes a connection between the brain and the limbs through the central nervous system, and repeatedly trains the limbs, especially hemiplegic limbs, to improve the training effect.

[0024] In use, the doctor or trainee can control the traction mechanism 22 through the controller 30 to automatically control the movement of the flexible elastic element 21 according to the training needs, and change the distance between the flexible elastic element 21 and the axis of the hinge shaft 13 to adapt to the different pedaling force requirements of different trainees; or, the same trainee can use different pedaling force requirements.

[0025] When the aforementioned center of gravity transfer balance trainer is in use, the controller 30 controls the traction mechanism 22 to pull the flexible elastic element 21 to move at the bottom of the box 11. When the distance between the flexible elastic element 21 and the axis of the hinge shaft 13 increases, the force required to step on the foot pedal 12 increases; when the distance between the flexible elastic element 21 and the axis of the hinge shaft 13 decreases, the force required to step on the foot pedal 12 decreases, so as to meet the different stepping force requirements of different users.

[0026] Because the strength of the two feet of a hemiplegic patient is different, with the foot on the hemiplegic side being weaker, the stepping force on both sides of the foot pedal 12 needs to be adjustable; the traction mechanism 22 includes a left traction mechanism 221 and a right traction mechanism 222, and the flexible elastic element 21 includes a left flexible elastic element 211 and a right flexible elastic element 212. The left traction mechanism 221 and the left flexible elastic element 211 are located on the left side of the hinge shaft 13, and the right traction mechanism 222 and the right flexible elastic element 212 are located on the right side of the hinge shaft 13.

[0027] like Figure 4-5 As shown, when using the aforementioned center-of-gravity transfer balance trainer, the controller 30 controls the left traction mechanism 221 to pull the left flexible elastic element 211 to the right at the bottom of the housing 11, changing the distance between the left flexible elastic element 211 and the axis of the hinge shaft 13, thus adjusting the stepping force on the left side of the foot pedal 12. For patients with left-leg hemiplegia, due to the relatively weak strength of the left leg, less stepping force is required to swing the foot pedal 12. When the left flexible elastic element 211 moves to the right, the distance between the left flexible elastic element 211 and the axis of the hinge shaft 13 decreases, and the force required for the left foot to swing the foot pedal 12 is reduced; conversely, the force required for the left foot to swing the foot pedal 12 is reduced. Alternatively, the controller 30 can control the right traction mechanism 222 to pull the right flexible elastic element 212 to the left at the bottom of the housing 11, changing the distance between the right flexible elastic element 212 and the hinge shaft 13, thus adjusting the stepping force on the right side of the foot pedal 12. For patients with right hemiplegia, due to the relatively weak strength of the right foot, less stepping force is needed to swing the foot pedal 12. When the right flexible elastic element 212 moves to the left, the distance between the right flexible elastic element 212 and the axis of the hinge shaft 13 decreases, and the force required for the right foot to swing the foot pedal 12 decreases; conversely, the force required for the right foot to swing the foot pedal 12 increases, thus adapting to the training requirements of different hemiplegic trainees. In order to detect data on the patient's center of gravity shift during training, the center of gravity shift detection device 31 includes an inclination sensor 310, which is installed on the foot pedal 12 and is used to detect the inclination angle of the foot pedal 12 swinging.

[0028] When using the aforementioned center of gravity transfer balance trainer, the trainee stands with both feet on either side of the axis of the foot pedal 12 hinge 13. The state of the foot pedal 12 includes a balanced state, a center of gravity shift to the left state, and a center of gravity shift to the right state. When the foot pedal 12 is in a balanced state, the tilt angle of the foot pedal 12 is either a flat angle of 180° or a 0° angle. The tilt sensor 310 transmits the flat angle data of the foot pedal 12 to the controller 30, and the controller 30 controls the center of gravity transfer display device 32 to display the balance data of the foot pedal 12. like Figure 6 As shown, when the center of gravity shifts to the left, the foot pedal 12 swings to the left, and the tilt angle of the foot pedal 12 is greater than 180° or 0°. The proportion of the center of gravity shifting to the left is proportional to the angle of the foot pedal 12 swinging counterclockwise. The tilt sensor 310 transmits the angle data of the foot pedal 12 swinging counterclockwise to the controller 30, and the controller 30 controls the center of gravity shift display device 32 to display the center of gravity shift data to the left. like Figure 7 As shown, when the center of gravity shifts to the right, the foot pedal 12 swings to the right. The tilt angle of the foot pedal 12 is less than 180° or 0°. The proportion of the center of gravity shifting to the right is proportional to the angle of the foot pedal 12 swinging clockwise. The tilt sensor 310 transmits the angle data of the foot pedal 12 swinging clockwise to the controller 30. The controller 30 controls the center of gravity shift display device 32 to display the center of gravity shift data to the right.

[0029] To detect the pressure of the foot pedal 12 swinging left and right, the center of gravity transfer detection device 31 includes a pressure sensor 320, which includes a left pressure sensor 3201 and a right pressure sensor 3202. The left pressure sensor 3201 is installed on the upper end of the left flexible elastic element 211 and is located between the foot pedal 12 and the left flexible elastic element 211. The right pressure sensor 3202 is installed on the upper end of the right flexible elastic element 212 and is located between the foot pedal 12 and the right flexible elastic element 212. The pressure sensor 320 is used to detect the gravity or pressure of the center of gravity transfer of the foot pedal 12.

[0030] When the aforementioned center of gravity transfer balance trainer is in use, when the foot pedal 12 is in a balanced state, the foot pedal 12 does not compress the left flexible elastic element 211 and the right flexible elastic element 212. The left pressure sensor 3201 and the right pressure sensor 3202 transmit their data to the controller 30. The controller 30 displays the left foot pedal force and the right foot pedal force of the foot pedal 12 as zero through the center of gravity transfer display device 32. When the center of gravity shifts to the left, the foot pedal 12 swings to the left. The left pressure sensor 3201 on the left flexible elastic element 211 is compressed by the left side of the foot pedal 12. The left pressure sensor 3201 transmits its pressure data to the controller 300. The controller 300 controls the center of gravity shift display device 32 to display the gravity data of the center of gravity shifting to the left. When the center of gravity shifts to the right, the foot pedal 12 swings to the right. The right pressure sensor 3202 on the right flexible elastic element 212 is compressed by the right side of the foot pedal 12. The right pressure sensor 3202 transmits its pressure data to the controller 300. The controller 300 controls the center of gravity shift display device 32 to display the gravity data of the center of gravity shifting to the right.

[0031] like Figure 1-3 The diagram shows the structure of an automatic flexible center of gravity transfer balance trainer driven by an electric push rod. The bottom of the housing 11 is provided with a slide groove 111 and a slide seat 210. The slide seat 210 is movably connected to the slide groove 111, and the flexible elastic element 21 is fixedly connected to the slide seat 210. The traction mechanism 22 includes an electric push rod 223. The outer shell of the electric push rod 223 is fixedly connected to the housing 11, and the drive rod of the electric push rod 223 is connected to the slide seat 210. The axis of the electric push rod 223 is perpendicular to the axis of the flexible elastic element 21, so as to realize the purpose of using the traction mechanism 22 to drive the flexible elastic element 21 to move, thereby adjusting the distance between the flexible elastic element 21 and the hinge shaft 13.

[0032] As shown in Figure 8-9, a schematic diagram of a motor-driven automatic flexible center of gravity transfer balance trainer is provided. The bottom of the housing 11 is provided with a slide groove 111, and a slide seat 210 is movably fitted to the slide groove 111. The flexible elastic element 21 is fixedly connected to the slide seat 210. The slide seat 210 is provided with a wheel 2101, and the axle of the wheel 2101 is movably fitted to the slide seat 210. The traction mechanism 22 includes a motor 224, the base of the motor 224 is fixedly connected to the slide seat 210, and the motor shaft of the motor 224 is connected to the axle of the wheel 2101. The motor 224 drives the wheel 2101 to rotate, thereby moving the slide seat 210. The slide seat 210 then moves the flexible elastic element 21 to adjust the distance between the flexible elastic element 21 and the hinge shaft 13.

[0033] The traction mechanism 22 includes an electric push rod, and a limit switch 225 is provided inside the housing of the electric push rod to control the stroke of the flexible elastic element 21. The controller 30 controls the distance of the drive rod of the electric push rod to move by controlling the working time of the electric push rod, so as to control the movement distance of the flexible elastic element 21. The controller 30 controls the left and right movement of the flexible elastic element 21 by controlling the extension or retraction of the drive rod of the electric push rod, so as to adjust the distance between the flexible elastic element 21 and the axis of the hinge shaft 13. Alternatively, the traction mechanism 22 includes a motor 224, and the slide 111 is equipped with a limit switch 225 for controlling the travel of the flexible elastic element 21. The controller 30 controls the rotation distance of the drive wheel 2101 of the motor 224 by controlling the working time of the motor 224, so as to control the movement distance of the flexible elastic element 21. By controlling the forward or reverse rotation of the motor 224, the left and right movement of the flexible elastic element 21 is controlled, so as to adjust the distance between the flexible elastic element 21 and the hinge shaft 13.

[0034] like Figure 10 The diagram shows the structure of the manually traction-based center of gravity transfer balance trainer. The bottom of the housing 11 is provided with a slide groove 111 and a slide seat 210. The slide seat 210 is movably connected to the slide groove 111, and the flexible elastic element 21 is fixedly connected to the slide seat 210. The traction mechanism 22 includes a traction rod 226, which is movably connected to the bushing 112 of the housing 11 and is connected to the slide seat 210.

[0035] In use, the slide block 210 is manually pulled by the handle 2261 of the traction rod 226, which drives the flexible elastic element 21 to move, changing the distance between the flexible elastic element 21 and the axis of the hinge shaft 13, so as to adjust the stepping force of the foot pedal 12.

[0036] In order to reduce the resistance to the movement of the flexible elastic element 21, the flexible elastic element 21 is provided with a guide block 2102, which is located above the pressure sensor 320 and is provided with a guide wheel 2103; so as to reduce the friction between the flexible elastic element 21 and the foot pedal 12.

[0037] When the aforementioned center of gravity transfer balance trainer is in use, the controller 30 controls the drive rod of the electric push rod of the traction mechanism 22 to drive the slide 210 to move; or, the controller 30 controls the motor 224 of the traction mechanism 22 to drive the wheel 2101 to rotate, thereby moving the slide 210; the slide 210 drives the flexible elastic element 21 to move, adjusting the distance between the flexible elastic element 21 and the axis of the hinge shaft 13, thus changing the torque between the foot pedal 12 and the axis of the hinge shaft 13; the trainee stands symmetrically on the left and right sides of the foot pedal 12. Training involves the trainee swaying the foot pedal 12 from side to side. When the flexible elastic element 21 moves toward the axis of the hinge 13, the trainee's stomping force on the foot pedal 12 decreases, meaning the pressure or gravity applied to the foot pedal 12 decreases as the trainee sways the foot pedal 12. When the flexible elastic element 21 moves away from the axis of the hinge 13, the trainee's stomping force on the foot pedal 12 increases, meaning the pressure or gravity applied to the foot pedal 12 increases as the trainee sways the foot pedal 12. This is to adapt to different stomping force requirements during training.

[0038] When the controller 30 controls the slide 210 to pull the flexible elastic element 21 to move, the pressure sensor 320 provided on the flexible elastic element 21 moves with the slide 210. When the left flexible elastic element 211 on the left side of the foot pedal 12 moves to the right, the left pressure sensor 3201 on the left flexible elastic element 211 detects that the pressure applied by the foot pedal 12 to the left flexible elastic element 211 decreases; when the left flexible elastic element 211 on the left side of the foot pedal 12 moves to the left, the left pressure sensor 3201 on the left flexible elastic element 211 detects that the pressure applied by the foot pedal 12 to the left flexible elastic element 211 increases. When the right flexible elastic element 212 on the right side of the foot pedal 12 moves to the left, the right pressure sensor 3202 on the right flexible elastic element 212 detects that the pressure applied by the foot pedal 12 to the right flexible elastic element 212 decreases; when the right flexible elastic element 212 on the right side of the foot pedal 12 moves to the right, the right pressure sensor 3202 on the right flexible elastic element 212 detects that the pressure applied by the foot pedal 12 to the right flexible elastic element 212 increases; this is to adapt to the different stepping force requirements of the left and right feet of hemiplegic patients, and to adapt to the different stepping force requirements of different trainees.

[0039] To enable the input of various training standard data or other data to the controller 30, the center of gravity transfer display device 32 includes a touch screen display 321, which includes a training data input box 3210. The center of gravity transfer training standard data is input through the training data input box 3210, and the center of gravity transfer detection device 31 detects the center of gravity transfer training process. The controller 30 calculates and judges whether the center of gravity transfer training has met the standard requirements, and displays the results through the center of gravity transfer display device 32. The center of gravity transfer training standard data includes: the proportion of left center of gravity transfer, the gravity force of left center of gravity transfer, the gravity force curve of left center of gravity transfer, the proportion of right center of gravity transfer, the gravity force of right center of gravity transfer, the gravity force curve of right center of gravity transfer, the number of pedal swings, the pedal swing frequency, and the training time, etc.

[0040] For other physiotherapy or therapeutic functions of weight transfer training, the aforementioned weight transfer balance trainer includes a foot physiotherapy device 40, which includes far-infrared physiotherapy foot pads 41. Two far-infrared physiotherapy foot pads 41 are provided and are symmetrically fixed on the left and right panels of the foot pedal 12.
