Description

Technical Field

[0001] The invention belongs to the field of rehabilitation medical equipment, and in particular relates to a novel whole-body vibration platform with double pedals. Background Art

[0002] Osteoporosis is a systemic bone disease caused by a variety of reasons, which leads to a decrease in bone density and quality, resulting in damage to bone microstructure, increased bone brittleness, and easy fracture. Osteoporosis may cause a decrease in height, back pain, decreased mobility and other serious complications. The current treatments for osteoporosis are mainly drug therapy and physical therapy, among which physical therapy is mainly extracorporeal shock wave therapy and whole body vibration training. Compared with extracorporeal shock wave therapy, whole body vibration training can more effectively improve neuronal excitability and motor unit synchronization, stimulate plantar fascia proprioceptors, and improve patients' muscle strength and coordination.

[0003] The existing platform device for whole-body vibration training has two vibration modes, one is the vertical vibration of the whole platform at the same time, frequency and direction, and the other is left-right alternating vibration. Among them, left-right alternating vibration can simulate the lower limb motion curve of normal physiological activities of the human body, and can transmit more acceleration to the patient's lower limbs compared to vertical vibration. The whole-body vibration platforms of left-right alternating vibration type on the market are all single-pedal and single-motor, providing vibration with a mechanical structure similar to a seesaw. When this vibration platform is in use, because the posture of the human body standing on the foot pedal is not completely symmetrical, it will lead to an unbalanced weight distribution on both sides, and this asymmetry will make the sum of the lateral forces provided by the vibration movement acting on the human foot in all directions not completely zero, which will have a negative impact on the accuracy of the vibration platform, resulting in the frequency and amplitude accuracy it can provide being lower than the ideal state. It will also cause the difference in acceleration between the left and right feet of the patient to gradually increase during the vibration process, causing the measurement of the phase between the right foot and the left foot to present a random tilt effect, which will have an adverse effect on the patient's sense of balance and training effect. Summary of the invention

[0004] The present application aims to solve the problem that the frequency and amplitude actually output by the whole-body vibration platform in the prior art are inconsistent with the preset ones, resulting in an increased difference in acceleration between the left and right feet during the vibration process. Furthermore, a vibration structure is proposed which adopts independent control of double pedals for the left and right feet and separate frequency and amplitude adjustment of double motors on a single-side pedal, and a new whole-body vibration platform with double pedals designed based on the structure.

[0005] The technical solution adopted by this application to solve the above technical problems is: A novel whole-body vibration platform with two pedals, each pedal being configured with: a piston device connected to the pedal through a first bearing device; a buoyancy arm located below the piston device and connected to the piston device through a first rotating connecting rod; a vibration amplitude adjustment device, comprising: a vibration amplitude disk, the buoyancy arm is mounted on the vibration amplitude disk through a second bearing device; a vibration amplitude adjustment motor, which is connected to a servo reducer; a rotation angle adjustment crank, one end of which is connected to a driving rod of the servo reducer, and the other end is connected to the vibration amplitude disk through a second rotating connecting rod, and the inclination angle of the vibration amplitude disk is adjusted under the drive of the servo reducer; a vibration frequency adjustment device, comprising: a rotating shaft connected to the buoyancy arm; a vibration frequency adjustment motor, which is connected to the rotating shaft through a rotation transmission mechanism and drives the buoyancy arm to rotate through the rotating shaft; the first rotating connecting rod is eccentrically arranged relative to the rotating shaft of the buoyancy arm.

[0006] The upper end of the first rotating connecting rod is rotationally connected to the first bracket fixed at the bottom of the piston device, and the lower end of the first rotating connecting rod is rotationally connected to the second bracket fixed at the top of the buoyancy arm. The rotation connection point between the first rotating connecting rod and the second bracket is eccentrically set relative to the rotation axis of the buoyancy arm.

[0007] The vibration amplitude disk is mounted on the rotation adjustment bracket and is suitable for adjusting the tilt angle relative to the rotation adjustment bracket.

[0008] The rotation transmission mechanism includes: a first synchronous pulley, which is coaxially arranged with the driving shaft of the vibration frequency adjustment motor; a second synchronous pulley, which is coaxially arranged with the rotating shaft, the first synchronous pulley and the second synchronous pulley are connected by a belt, and a tensioner is also arranged on the belt, and the tensioner is equipped with a rotating tensioner shaft.

[0009] An inertia flywheel is installed on the rotating shaft.

[0010] The novel whole-body vibration platform with two pedals is also provided with a rotating servo mounting plate, on which the vibration frequency adjustment motor and the vibration amplitude adjustment motor are mounted; a rotating main flange is provided below the rotating adjustment bracket, and the rotating main flange is also mounted on the rotating servo mounting plate; The rotating shaft passes through the vibration amplitude disk, the rotation adjustment bracket and the rotation servo mounting plate, and a third bearing device is arranged at the lower end of the rotating shaft; the driving shaft of the vibration frequency adjustment motor passes through the rotation servo mounting plate, and the rotation transmission mechanism is located between the third bearing device and the rotation servo mounting plate.

[0011] The novel whole-body vibration platform with two pedals also includes: a bus multi-axis controller connected to the vibration frequency adjustment motor and the vibration amplitude adjustment motor of the pedals on both sides; a PLC controller connected to the bus multi-axis controller; a human-computer interaction touch screen connected to the PLC controller for inputting vibration parameter instructions; and a multi-function handle connected to the PLC controller and provided with three functions of start, stop and reset.

[0012] The novel whole-body vibration platform with two pedals is also provided with a whole machine housing, the two pedals are installed on the plane of the whole machine housing, handrails are installed on both sides of the double pedals, the human-computer interaction touch screen is arranged on the table in front of the pedals, and the multi-function handle is arranged below the human-computer interaction touch screen; a control cabinet housing is arranged on the whole machine housing, and the bus multi-axis controller and the PLC controller are placed in the control cabinet housing; an emergency stop button is also arranged on the whole machine housing, and the emergency stop button is connected to the power supply of the vibration frequency adjustment motor and the vibration amplitude adjustment motor.

[0013] The method of using the novel whole-body vibration platform with two pedals is as follows: the vibration amplitude of the pedals on both sides is adjusted by a motor to make the amplitude of the pedals on both sides consistent, but in the initial state, the vibration phase of the pedals on both sides differs by half a cycle; the vibration frequency of the pedals on both sides is adjusted by a motor to make the vibration frequency of the pedals on both sides consistent.

[0014] The amplitude range of the pedals on both sides is controlled to be 0-4mm, and the minimum adjustment accuracy is 0.05mm; the vibration frequency range of the pedals on both sides is controlled to be 0-70Hz, and the minimum adjustment accuracy is 1 Hz; the response time of the vibration frequency adjustment motor in the start-stop stage is less than 0.8s.

[0015] The advantages of the novel double-pedal whole body vibration platform of the present invention are: (1) The dual-pedal novel whole-body vibration platform described in the present invention uses two different motors on each side of the pedal to control the frequency and amplitude respectively. The dual-pedal independent oscillation can effectively avoid the increase in the acceleration difference between the left and right feet during the vibration process, and can also better adjust the phase difference between the two feet at the beginning of the vibration, simulating the simple harmonic motion curve of normal physiological activities of the human body. The present invention uses the eccentric rotation of the buoyancy arm as the vibration principle. During the rotational vibration, the same acceleration will be generated in all directions of the plane, that is, the acceleration in each direction is offset, eliminating the hidden danger of displacement of the entire device during the vibration process. The vibration structure of the single-pedal dual motor separate adjustment of frequency and amplitude in the present invention reduces the required motor torque and power, greatly reducing the requirements of the motor compared to the single pedal. At the same time, the separation control is not affected by the torque reduction of the single motor at high frequency, and can still ensure accurate high amplitude when reaching high frequency, realizing accurate control of the whole-body vibration frequency and amplitude, and the output under heavy load can also be consistent with the preset parameters. In addition, the adjustable range of the vibration parameters is wide, and the continuous adjustment of the vibration frequency and amplitude can be achieved. Compared with the stage-by-stage adjustment method in the prior art, it can better meet the different requirements of different users for vibration parameters.

[0016] In the whole body vibration treatment and research of osteoporosis, it is very important to determine the treatment parameters of vibration frequency and amplitude. However, the whole body vibration platform currently used cannot ensure that the output parameters are consistent with the preset parameters due to mechanical structure and other problems, which greatly limits the development of research. This device can provide accurate incremental input vibration parameters, and the error between the actual output and input parameters is extremely small, providing a rigorous experimental environment for experimenters, and the quantitative and accurate vibration parameters also provide greater guarantee for the treatment effect of osteoporosis patients.

[0017] (2) The dual-pedal novel whole-body vibration platform described in the present invention, when the vibration is completed or the emergency stop button is pressed, the vibration frequency adjustment motor stops within 0.8s, and the rotating inertia flywheel gradually reduces the rotation speed of the rotating shaft by using the remaining rotation inertia, so that the buoyancy arm gradually reduces the rotation speed to stop the pedal vibration, avoiding human discomfort caused by abrupt changes in acceleration. Similarly, during the startup phase, the inertia flywheel can also play a buffering role to avoid sudden discomfort to the human body.

[0018] (3) The dual-pedal new whole-body vibration platform described in the present invention has armrests and handles on the device housing to stabilize the user's posture; there is an emergency stop button next to the interactive touch screen to ensure user safety. When the vibration platform in the present invention is in use, the noise generated by the device itself is very small, and the inner side of the device housing can be filled with silent cotton to further reduce the operating noise.

[0022] This embodiment provides a novel whole body vibration platform with two pedals, such as Figure 1 and Figure 2As shown, each side pedal 1 is equipped with a vibration system, including a piston device 2 and a buoyancy arm 4, wherein the piston device 2 is connected to the pedal 1 through a first bearing device 3, the first bearing device 3 uses a high-speed bearing, and the first bearing device 3 is installed on the bottom surface of the pedal 1, and the piston device 2 is suitable for moving in the up and down directions, thereby driving the pedal 1 to rise and fall. The buoyancy arm 4 is located below the piston device 2 and is connected to the piston device 2 through a first rotating connecting rod 5.

[0023] The single-sided pedal in this embodiment is provided with a dual-motor separation control system consisting of a vibration amplitude adjustment device and a vibration frequency adjustment device. The vibration amplitude adjustment device includes a vibration amplitude disk 8, a vibration amplitude adjustment motor 9 and a rotation angle adjustment crank 10. The buoyancy arm 4 is mounted on the vibration amplitude disk 8 through a second bearing device. A servo reducer 11 is connected to the vibration amplitude adjustment motor 9; one end of the rotation angle adjustment crank 10 is connected to the driving rod of the servo reducer 11, and the other end is connected to the vibration amplitude disk 8 through a second rotating connecting rod 12, and the vibration amplitude disk 8 is linked through the second rotating connecting rod 12. The vibration amplitude disk 8 is controlled by the vibration amplitude adjustment motor 9 and the servo reducer 11 to rotate relative to the driving rod, thereby driving the vibration amplitude disk 8 to move in the tilting direction to adjust the tilting angle. As a preferred embodiment, the vibration amplitude disk 8 is mounted on the rotation adjustment bracket 13 through a horizontal axis 14, which is suitable for adjusting the tilting angle relative to the rotation adjustment bracket 13.

[0024] The vibration frequency adjustment device includes a rotating shaft 15, which is connected to the buoyancy arm 4. In this embodiment, the rotating shaft 15 is fixedly connected to the buoyancy arm 4 through a rotating main shaft pin 16. A vibration frequency adjustment motor 17 is also provided, which is connected to the rotating shaft 15 through a rotation transmission mechanism, and drives the buoyancy arm 4 to rotate through the rotating shaft 15. In this embodiment, the rotation connection point between the first rotating link 5 and the second bracket 7 is eccentrically arranged relative to the rotating shaft 15 of the buoyancy arm 4, so the first rotating link 5 is eccentrically arranged relative to the rotating shaft 15 of the buoyancy arm 4. The rotation transmission mechanism includes a first synchronous pulley 18 and a second synchronous pulley 19, wherein the first synchronous pulley 18 is coaxially arranged with the driving shaft of the vibration frequency regulating motor 17; the second synchronous pulley 19 is coaxially arranged with the rotating shaft 15, the first synchronous pulley 18 and the second synchronous pulley 19 are connected by a belt 20, a tensioner is arranged inside the belt 20, and a rotating tensioner shaft is provided at the center of the tensioner for adjusting the size of the tensioner. As a preferred embodiment, an inertia flywheel is installed on the rotating shaft 15.

[0025] In order to ensure the stability of operation, the vibration platform is also provided with a rotating servo mounting plate, on which the vibration frequency adjustment motor 17 and the vibration amplitude adjustment motor 9 are installed; a rotating main flange is provided below the rotating adjustment bracket 13, and the rotating main flange is also installed on the rotating servo mounting plate. The lower end of the rotating shaft 15 passes through the vibration amplitude disk 8, the rotating adjustment bracket 13 and the rotating servo mounting plate, and a third bearing device is provided at the lower end of the rotating shaft 15; the driving shaft of the vibration frequency adjustment motor 17 passes through the rotating servo mounting plate, and the rotation transmission mechanism is located between the third bearing device and the rotating servo mounting plate.

[0026] The novel whole-body vibration platform with two pedals is also provided with a bus multi-axis controller, which is connected to the vibration frequency adjustment motor 17 and the vibration amplitude adjustment motor 9 of the pedals on both sides, and is connected to the bus multi-axis controller with a PLC controller; in order to realize human-computer interaction, the vibration platform is provided with a human-computer interaction touch screen and a multi-function handle, which is connected to the PLC controller for inputting vibration frequency, vibration amplitude and vibration time instructions; the multi-function handle is also connected to the PLC controller. The multi-function handle is provided with three functions: start, stop and reset. After the stop function is pressed, the motor stops working and the vibration ends, but the set amplitude will not return to zero at this time, that is, if the start button is continued to be pressed, it will vibrate according to the last amplitude. Pressing the reset button can return the amplitude to zero. After the vibration starts, the "reset function" is locked, and pressing the reset button is invalid; when the reset button is pressed, the start function is invalid because the amplitude returns to zero.

[0027] The new whole-body vibration platform with double pedals is also provided with a whole machine housing, and the whole machine sheet metal housing is adopted in this embodiment. The two pedals 1 are installed on the plane of the whole machine housing, and the third bearing device at the lower end of the rotating shaft 15 is fixed on the bottom plate of the whole machine housing. Handrails are installed on both sides of the double pedals, and the human-machine interactive touch screen is arranged on the table in front of the pedals 1, and the multi-function handle is arranged below the human-machine interactive touch screen; a control cabinet housing is arranged on the whole machine housing, and the bus multi-axis controller and the PLC controller are placed in the control cabinet housing; an emergency stop button is also arranged on the whole machine housing. In order to prevent emergencies, the emergency stop button is connected to the power supply, and the power is immediately cut off after being pressed. At this time, the motor stops working immediately, and the amplitude will not be reset to 0. In this embodiment, the emergency stop button is arranged next to the human-machine interactive touch screen. The vibration platform can be connected to an external power supply for supplying power to all electrical components, and a power indicator light is also arranged on the table of the whole machine housing.

[0028] The method of using the novel double-pedal whole body vibration platform in this embodiment is as follows: Before using, the user should connect the power cord of the vibration platform to a 220V power supply, and the power indicator light will be green. When using, stand on the left pedal with your left foot and the right pedal with your right foot, select the required vibration frequency, amplitude and vibration time on the human-computer interactive touch screen, hold the armrest if necessary, and finally press the start button on the multi-function handle to start vibration.

[0029] The vibration amplitude of the pedals on both sides is controlled by the vibration amplitude adjustment motor 9. At this time, in the rotating lifting vibration structure of the single-side pedal, the vibration amplitude adjustment motor 9 changes the angle of the rotation angle adjustment crank 10 through the servo reducer 11, so that the angle of the rotating connecting rod changes, thereby adjusting the pitch angle of the vibration amplitude disk 8. The buoyancy arm 4 fits the vibration amplitude disk 8, which will cause the buoyancy arm 4 to have an inclination angle, and the second bracket 7 located at the upper end of one side of the buoyancy arm 4 will also be tilted. The vibration amplitude adjustment motor 9 of the pedals on both sides is used to control the vibration amplitude of the two sides to be consistent, and the vibration frequency adjustment motor 17 is used to control the vibration frequency of the pedals 1 on both sides to be consistent. The vibration frequency adjustment motor 17 works at a preset frequency, and its driving rod drives the first synchronous pulley 18 to rotate, and drives the rotating shaft 15 to rotate through the transmission belt 20, the tensioner, and the second synchronous pulley 19. The rotating shaft 15 is connected to the buoyancy arm 4 through the rotating main shaft pin 16. When the rotating shaft 15 rotates, the buoyancy arm 4 rotates at the same speed. When the inclined buoyancy arm 4 drives the second bracket 7 to rotate along the vibration amplitude disk 8 at a certain pitch angle, the second bracket 7 performs eccentric rotation on the vibration amplitude disk 8, and the pedal 1 is lifted up by the first rotating connecting rod 5 and the piston device 2 on the side of the vibration amplitude disk 8 with a higher horizontal position, and the pedal 1 is lowered on the side of the vibration amplitude disk 8 with a lower horizontal position. After the start instructions of the vibration frequency adjustment motors 17 on both sides are issued at the same time, the amplitude and vibration frequency are kept consistent, but the vibration phases of the pedals 1 on both sides differ by half a cycle in the initial state, so that when the vibration of the pedal 1 starts, the left and right sides vibrate with the same frequency and amplitude, but in opposite directions, thereby simulating the coordinated movement of the left and right feet of the human body. When the pedal 1 vibrates up and down periodically, its displacement height variation curve over time is a simple harmonic wave. During the vibration process, the amplitude of the pedals on both sides is controlled by the vibration amplitude adjustment motor 9 to be in the range of 0-4mm, and the minimum adjustment accuracy is 0.05mm; the vibration frequency of the pedals on both sides is controlled by the vibration frequency adjustment motor 17 to be in the range of 0-70Hz, and the minimum adjustment accuracy is 1 Hz; the response time of the vibration frequency adjustment motor 17 in the start-stop stage is less than 0.8s.

[0030] When the vibration is completed or the emergency stop button is pressed, the vibration frequency regulating motor stops within 0.8s, and the inertia flywheel 23 gradually reduces the rotation speed of the rotating shaft 15 using the remaining rotation inertia, so that the buoyancy arm 4 gradually reduces the rotation speed to stop the pedal vibration, avoiding human discomfort caused by the sudden change in acceleration.

[0031] The above-mentioned embodiments only express several implementation methods of the present invention, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the scope of the patent of the present invention. It should be pointed out that, for those of ordinary skill in the art, several variations and improvements can be made without departing from the concept of the present invention, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the patent of the present invention shall be subject to the claims.
