Description

Technical Field

[0001] The present invention relates to the technical field of medical devices, and particularly to a balance training device. Background Art

[0002] In the field of rehabilitation medicine, the restoration of balance ability is a crucial rehabilitation link for many patients; with the aggravation of population aging and the increase in the number of patients with nervous system and motor system injuries caused by various accidents and chronic diseases, many patients have a decline in physical balance ability due to reasons such as nervous system injury, after orthopedic surgery, or old age and physical weakness.

[0003] Traditional balance training devices are relatively simple. Some are just simple balance boards, and patients can only perform limited center-of-gravity transfer exercises in a static environment, making it difficult to simulate dynamic scenarios in real life and unable to effectively improve the balance ability to cope with complex situations. Some more advanced devices can achieve a certain degree of swaying, but usually limited to a single direction. For example, a device that can only sway left and right can only exercise the muscle regulation and center-of-gravity control of the patient in that lateral direction, and there is insufficient balance perception stimulation in the front-back direction; conversely, a device with only front-back swaying function also has the same problem. This means that if patients want to comprehensively improve their multi-directional balance ability, they have to switch between various training devices with different functions, consuming a large amount of time, energy, and rehabilitation costs. Summary of the Invention

[0004] In view of the problems existing in the use of the above-mentioned traditional balance training devices, the present invention is proposed.

[0005] Therefore, the purpose of the present invention is to provide a balance training device that enables patients to conveniently perform left-right swaying balance training and front-back swaying balance training on the same device, and at the same time achieve the purpose of efficient, accurate, and personalized balance training.

[0006] To achieve the above purpose, the present invention provides the following technical solutions:

[0007] A balance training device includes a base frame. A placement groove is formed in the base frame, and a U-shaped mounting frame is fixedly installed on the surface of the base frame and outside the placement groove. The four corners of the top surface of the U-shaped mounting frame are evenly fixedly installed with the feet of a support frame, and a monitoring sensor probe is fixedly provided at the end of each foot of the support frame. A control panel is fixedly installed on the top of the support frame, and a control module is arranged in the control panel. The monitoring sensor probe is electrically connected to the control module;

[0008] A front-back swaying assembly is arranged inside the swaying outer frame, and the front-back swaying assembly is fixedly connected to a balance foot pedal to control the front-back swaying of the balance foot pedal;

[0009] A bottom support plate is fixedly installed on the bottom surface of the placement groove. Driving cylinders A are fixedly installed at the left and right ends of the bottom support plate respectively, and the output shafts of the driving cylinders A are rotatably connected to the swinging outer frame. A balance foot pedal is arranged at the top end of the swinging outer frame. By sequentially driving the driving cylinders A at the left and right ends of the bottom support plate, the swinging outer frame drives the balance foot pedal to swing left and right.

[0010] Preferably, a conductive rubber anti-slip pad is laid on the surface of the balance foot pedal. A pressure sensor array is built in the conductive rubber anti-slip pad. The data collected by the pressure sensor array is transmitted to the control module through a circuit and visually presented on the display screen of the control panel, enabling medical staff to intuitively grasp the sole pressure distribution of the patient.

[0011] Preferably, the front and rear swinging assembly includes two groups of guide rods. A fixing plate is fixedly installed on the inner wall of the swinging outer frame. The two groups of guide rods are respectively movably installed at the front and rear ends of the bottom surface of the balance foot pedal. The guide rods slide through the fixing plate, and a guide seat is fixedly installed at the bottom of the guide rods. A transmission mechanism is arranged at the bottom of the guide seat, and the transmission mechanism can sequentially lift the two guide seats;

[0012] Guide grooves are formed on the surface of the swinging outer frame, and the two groups of guide rods slide in the guide grooves. The bottom surface of the swinging outer frame is fixedly connected to the mounting plate through a spring frame A. The mounting plate is fixedly installed on the surface of the fixing plate, and the spring frame A plays a role in supporting the balance foot pedal.

[0013] Preferably, the transmission mechanism includes a motor. The motor is fixedly installed on the inner wall of the swinging outer frame. The output shaft of the motor is fixedly connected to a transmission rod. The other end of the transmission rod is rotatably connected to the inner wall of the swinging outer frame. Transmission cams are fixedly sleeved at both ends of the transmission rod, and the protruding directions of the two transmission cams are opposite to each other. When the motor drives the transmission rod to rotate, the two transmission cams will rotate synchronously. Due to their opposite protruding directions, they can respectively, sequentially and crosswise lift the guide seats located above them. The action of the lifted guide seats is conducted through the guide rods connected thereto, and finally drives the balance foot pedal to swing back and forth. The motor is electrically connected to the control module.

[0014] Preferably, a fixed rotating seat is rotatably sleeved on the outer side of the transmission rod. The fixed rotating seat is fixedly installed on the surface of the swinging outer frame.

[0015] Preferably, a plugging groove is formed on one side of the guide rod. A stabilizing mechanism is fixedly installed on the upper surface of the fixing plate. The stabilizing mechanism cooperates with the plugging groove to fix the guide rod, so as to make the balance foot pedal horizontal.

[0016] Preferably, the stabilizing mechanism includes a driving cylinder B, which is fixedly installed on the surface of the fixed plate. A plugging rod is slidably arranged in the output end of the driving cylinder B. A spring frame B is sleeved in the middle of the plugging rod. One end of the spring frame B is fixedly connected to the surface of the plugging rod, and the other end is fixedly connected to the surface of the output end of the driving cylinder B. The plugging rod is slidably spliced with the plugging groove. The driving cylinder B is electrically connected to the control module.

[0017] In the above technical solution, the technical effects and advantages provided by the present invention are as follows:

[0018] In the present invention, by setting the front-back swing assembly and the left-right swing structure, the patient can conveniently perform left-right swing balance training and front-back swing balance training on the same device, comprehensively improving the patient's multi-directional balance ability, without having to move between various training devices with different functions, saving the patient's time, energy and rehabilitation costs; among them, in the transmission mechanism of the front-back swing assembly, the motor drives the transmission rod to rotate, and the convex directions of the transmission cams at both ends of the transmission rod are opposite, which can respectively, sequentially and crosswise lift the guide seat, and then drive the balance foot pedal to swing back and forth. This design structure is simple and stable, ensuring the smooth progress of the front-back swing action; among them, the left-right swing is realized by sequentially driving the driving cylinders A at the left and right ends of the bottom support plate, so that the swing outer frame drives the balance foot pedal to swing left and right, which is convenient to operate and the swing amplitude can be adjusted according to needs; in order to ensure the level of the balance foot pedal during the left-right swing, the driving cylinder B can be started, and the output end of the driving cylinder B drives the plugging rod to move towards the direction close to the guide rod. During this process, when the plugging rod abuts against the outer wall of the guide rod, it moves into the output end of the driving cylinder B, and at the same time compresses the spring frame B. When the guide rod is driven by the transmission cam to move upward, the plugging rod is inserted into the plugging groove to fix the guide rod, and similarly, the other guide rod can also be fixed. Finally, it is ensured that the balance foot pedal follows the swing outer frame to smoothly realize the left-right swing action while maintaining a horizontal state, providing stable and accurate balance training conditions for the patient.

[0019] In the present invention, by laying a conductive rubber anti-slip pad on the surface of the balance foot pedal and internally arranging a pressure sensor array, the pressure distribution data of the patient's soles can be collected and transmitted to the control module through the circuit, and visually presented on the display screen of the control panel, so that the medical staff can intuitively master the pressure distribution of the patient's soles, and thus more accurately formulate a personalized balance training plan for the patient to improve the training effect.

Detailed implementation manners

[0028] In order to enable those skilled in the art to better understand the technical solutions of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings.

[0029] An embodiment of the present invention discloses a balance training device.

[0030] Referring to Figures 1-5 , a balance training device includes a base frame 1. A placement groove 5 is provided inside the base frame 1. A U-shaped mounting frame 2 is fixedly installed on the surface of the base frame 1 and outside the placement groove 5. The top surface of the U-shaped mounting frame 2 is evenly fixed with the feet of the support frame 3, and a monitoring sensor probe 301 is fixedly provided at the end of each foot of the support frame 3. A control panel 4 is fixedly installed on the top of the support frame 3. A control module is provided inside the control panel 4. The monitoring sensor probe 301 is electrically connected to the control module; the monitoring sensor probe 301 is used to monitor the state of the patient during training in real time;

[0031] A front-back swing component is arranged inside the swing outer frame 6, and the front-back swing component is fixedly connected to the balance foot pedal 9. The front-back swing component controls the front-back swing of the balance foot pedal 9;

[0032] A bottom support plate 7 is fixedly installed on the bottom surface of the placement groove 5. Driving cylinders A8 are respectively fixedly installed at the left and right ends of the bottom support plate 7. The output shafts of the driving cylinders A8 are rotatably connected to the swing outer frame 6. A balance foot pedal 9 is arranged at the top of the swing outer frame 6. The swing outer frame 6 can swing in the placement groove 5. By sequentially driving the driving cylinders A8 at the left and right ends of the bottom support plate 7, the swing outer frame 6 drives the balance foot pedal 9 to swing left and right.

[0033] A conductive rubber anti-slip pad 10 is laid on the surface of the balance foot pedal 9. A pressure sensor array 11 is built into the conductive rubber anti-slip pad 10. The data collected by the pressure sensor array 11 is transmitted to the control module through a circuit and visually presented on the display screen of the control panel 4, enabling medical staff to intuitively grasp the sole pressure distribution of the patient.

[0034] The front-back swing component includes two groups of guide rods 18. A fixing plate 601 is fixedly installed on the inner wall of the swing outer frame 6. The two groups of guide rods 18 are respectively movably installed at the front and rear ends of the bottom surface of the balance foot pedal 9. The guide rods 18 slidably penetrate through the fixing plate 601. A guide seat 19 is fixedly installed at the bottom of the guide rod 18. A transmission mechanism is arranged at the bottom of the guide seat 19, and the transmission mechanism can sequentially lift the two groups of guide seats 19;

[0035] Guide grooves 602 are formed on the surface of the swing outer frame 6, and the two groups of guide rods 18 slide in the guide grooves 602. The bottom surface of the swing outer frame 6 is fixedly connected to the mounting plate 17 through a spring frame A16. The mounting plate 17 is fixedly installed on the surface of the fixing plate 601. The spring frame A16 plays a role in supporting the balance foot pedal 9.

[0036] The transmission mechanism includes a motor 12. The motor 12 is fixedly installed on the inner wall of the swing outer frame 6. The output shaft of the motor 12 is fixedly connected to a transmission rod 13. The other end of the transmission rod 13 is rotatably connected to the inner wall of the swing outer frame 6. Transmission cams 15 are firmly fixedly sleeved at both ends of the transmission rod 13, and the protruding directions of these two transmission cams 15 are opposite to each other. When the motor 12 drives the transmission rod 13 to rotate, the two transmission cams 15 will rotate synchronously. Due to their opposite protruding directions, they can respectively, sequentially and crosswise lift the guide seats 19 located above them. The action of the guide seats 19 being lifted will be conducted through the guide rods 18 connected to them, ultimately driving the balance foot pedal 9 to achieve front-back swing. The motor 12 is electrically connected to the control module.

[0037] A fixed rotating seat 14 is rotatably sleeved on the outer side of the transmission rod 13. The fixed rotating seat 14 is fixedly installed on the surface of the swing outer frame 6.

[0038] One side of the guide rod 18 is provided with a plugging groove 23, and a stabilizing mechanism is fixedly installed on the upper surface of the fixed plate 601. The stabilizing mechanism cooperates with the plugging groove 23 to fix the guide rod 18, so as to make the balance foot pedal 9 horizontal.

[0039] The stabilizing mechanism includes a driving cylinder B20, which is fixedly installed on the surface of the fixed plate 601. A plugging rod 21 is slidably arranged in the output end of the driving cylinder B20. A spring frame B22 is sleeved in the middle of the plugging rod 21. One end of the spring frame B22 is fixedly connected to the surface of the plugging rod 21, and the other end is fixedly connected to the surface of the output end of the driving cylinder B20. The plugging rod 21 is slidably spliced with the plugging groove 23. The driving cylinder B20 is electrically connected to the control module;

[0040] It should be noted that when realizing the left - right swing function, it is achieved by means of the driving cylinders A8 at the left and right ends of the bottom support plate 7; by sequentially driving these two driving cylinders A8, the swing outer frame 6 can be promoted to swing left and right, and then drive the balance foot pedal 9 to swing left and right synchronously. This operation mode is not only simple and easy to implement, but also has a significant advantage, that is, it can flexibly adjust the swing amplitude according to the actual training needs to adapt to the training conditions of different patients; at the same time, in order to ensure that the balance foot pedal 9 always maintains a horizontal state during the left - right swing process, a driving cylinder B20 is specially set. After the driving cylinder B20 is started, its output end will exert force to push the plugging rod 21, so that the plugging rod 21 moves towards the direction close to the guide rod 18. During the process of the plugging rod 21 gradually approaching the guide rod 18, once the end of it touches the outer wall of the guide rod 18, it will receive a reaction force and retract into the output end of the driving cylinder B20. During this period, the spring frame B22 will be compressed due to the retraction action of the plugging rod 21 and start to accumulate elastic potential energy. When the guide rod 18 moves upward driven by the transmission cam 15, the previously retracted plugging rod 21 will, under the action of the elastic restoring force of the spring frame B22, be inserted into the pre - set plugging groove 23 on one side of the guide rod 18; in this way, the guide rod 18 is firmly fixed. According to the same principle, the other guide rod 18 is also fixed, and finally it is ensured that the balance foot pedal 9 follows the swing outer frame 6 to smoothly realize the left - right swing action while maintaining a horizontal state, providing stable balance training conditions for patients.

[0041] In the present invention, when performing the front - back swing training:

[0042] The patient stands on the balance foot pedal 9, starts the motor 12, and the motor 12 drives the transmission rod 13 to rotate. The two transmission cams 15 rotate synchronously, respectively, successively and crosswise to push up the guide seat 19 located above it. The movement of the guide seat 19 is conducted through the guide rod 18, driving the balance foot pedal 9 to swing back and forth, and performing balance training in the front and back directions for the patient; medical staff can also set the rotation parameters of the motor 12, such as the rotation speed, etc., on the control panel 4 to adjust the amplitude and speed of the back-and-forth swing.

[0043] When performing left and right swing training:

[0044] First, it is necessary to adjust and fix the balance foot pedal 9 horizontally: The control module can be used to control the action of the stabilizing mechanism; the driving cylinder B20 is fixedly installed on the surface of the fixed plate 601, and the insertion rod 21 is slidably arranged inside its output end. A spring frame B22 is sleeved in the middle of the insertion rod 21. One end of the spring frame B22 is fixedly connected to the surface of the insertion rod 21, and the other end is fixedly connected to the surface of the output end of the driving cylinder B20. The control module controls the driving cylinder B20 to extend, so that the insertion rod 21 is inserted into the insertion slot 23 on one side of the guide rod 18, thereby fixing the guide rod 18 and keeping the balance foot pedal 9 horizontal; Subsequently, the patient stands on the balance foot pedal 9, and the control module sequentially drives the driving cylinders A8 at the left and right ends of the bottom support plate 7. The telescopic action of the driving cylinder A8 drives the swing outer frame 6 to swing left and right, thereby realizing the left and right swing of the balance foot pedal 9 and performing balance training in the left and right directions for the patient; medical staff can set the driving parameters of the driving cylinder A8, such as the telescopic speed, swing amplitude, etc., on the control panel 4 according to the actual situation of the patient; When front and back swing training is required, the control module controls the driving cylinder B20 to retract, pulls out the insertion rod 21, releases the fixation of the guide rod 18, and the balance foot pedal 9 can perform front and back swing.

[0045] It is worth noting that this device can provide balance training for front and back swing or left and right swing, but cannot perform front, back, left, and right swing training simultaneously;

[0046] Pressure monitoring and feedback: When the patient is training on the balance foot pedal 9, the pressure sensor array 11 built in the conductive rubber anti-slip pad 10 on the surface of the balance foot pedal 9 will collect the data of the pressure distribution on the patient's sole. These data are transmitted to the control module through the circuit. After the control module processes the data, it is visually presented on the display screen of the control panel 4; medical staff can understand the pressure distribution on the patient's sole in real time according to the data on the display screen, judge the balance state of the patient, and adjust the training plan accordingly, such as adjusting the parameters of left and right or front and back swing.

[0047] It should be understood that the embodiments of the present application are not limited to the exact structures already described and shown in the drawings, and various modifications and changes can be made without departing from its scope. The scope of the embodiments of the present application is only limited by the appended claims.

[0048] The above-described embodiments merely represent several implementation manners of the embodiments of the present application. The description thereof is relatively specific and detailed, but it should not be construed as a limitation on the scope of the invention patent. It should be noted that for those of ordinary skill in the art, without departing from the concept of the embodiments of the present application, several deformations and improvements can still be made, and these all belong to the protection scope of the embodiments of the present application.
