Description

Technical Field

[0001] This application relates to the field of rehabilitation training equipment technology, and further to a balance table and balance training device. Background Technology

[0002] In recent years, with the continuous development of the global fitness and rehabilitation industry, the market size of balance training devices has also expanded significantly due to their diverse training modes, customizable personalized training programs, and ease of operation.

[0003] In practical applications, such as balance training in rehabilitation medicine, patients stand on the balance platform of a balance training device and perform corresponding movements according to the doctor's instructions or on-screen prompts. The pressure sensor array inside the balance platform measures the patient's center of gravity data in real time to display the patient's center of gravity shift and help determine their balance ability. In the industry, conventional balance training devices often wobble when placed on the ground due to uneven surfaces, affecting the collection of center of gravity data. Currently, the balance platform is usually lifted and its supporting legs are rotated to adjust their height for stable placement. However, balance platforms are typically flat, making the above method of adjusting the height of the supporting legs inconvenient and requiring multiple adjustments and tests to achieve a leveling effect. The leveling process is cumbersome and needs improvement. Summary of the Invention

[0004] The purpose of this application is to provide a balancing force table and a balancing training device, which simplifies the leveling steps of the balancing force table of the balancing training device and improves the efficiency and convenience of the leveling operation.

[0005] The technical solution provided in this application is as follows:

[0006] On one hand, this application provides a balancing force table, comprising:

[0007] Support platform;

[0008] Multiple pressure sensors are located below the support platform to detect the pressure distribution on the support platform;

[0009] Multiple support legs are provided below the support platform to support the support platform; and at least one of the multiple support legs is an adjustable support leg.

[0010] A transmission mechanism is located below the support platform and is connected to the adjustable support legs via a transmission mechanism.

[0011] An adjusting component is located on the side of the support platform. It is connected to the transmission mechanism and constitutes the power input end of the transmission mechanism. It is used to drive the transmission mechanism to adjust the height of the adjustable support leg in the vertical direction.

[0012] This application provides a balancing platform. In practical applications, the user operates the adjusting mechanism according to the placement of the platform. The adjusting mechanism drives the transmission mechanism, which in turn moves the adjustable legs vertically up and down relative to the support platform, adjusting the height of the corresponding adjustable legs to achieve stable placement of the balancing platform on the ground. Compared to the leveling methods in the aforementioned related technologies, the leveling process of this balancing platform does not require lifting the entire platform or repeatedly twisting the legs and testing its stability. The user only needs to operate the adjusting mechanism from the side of the platform, and the leveling operation is completed once overall stability is observed. This balancing platform leveling operation is convenient, efficient, easy to use, and provides a superior user experience.

[0013] In some embodiments, the transmission mechanism further includes a driven gear and a transmission element;

[0014] The driven gear is sleeved on the adjustable support leg and is coaxially connected to the adjustable support leg for transmission.

[0015] The transmission component is rotatably arranged relative to the support platform about its own axis, and is connected to the driven gear and the adjusting component in a transmission manner;

[0016] The power input end of the transmission component is connected to the adjustment component in a transmission manner;

[0017] The power output end of the transmission component is connected to the driven gear to drive the adjustable support leg to rotate relative to the support platform for height adjustment.

[0018] This application provides a balancing force table, in which a driven gear is coaxially mounted on an adjustable support leg, and a transmission component is provided between the adjusting component and the driven gear. The transmission component connects the adjusting component and the adjustable support leg. When the user operates the adjusting component, it drives the transmission component and the driven gear to rotate sequentially, thereby causing the adjustable support leg to rotate relative to the support platform around its own axis, thus adjusting the height of the adjustable support leg. The lifting drive structure of the adjustable support leg is simple and can be configured in various ways, which helps reduce the production difficulty of the balancing force table and facilitates cost reduction and efficiency improvement for enterprises.

[0019] In some embodiments, the adjusting member includes a first handwheel, the axis of rotation of which is vertically oriented;

[0020] The transmission component includes a first gear, which is coaxially fixed below the first handwheel;

[0021] The driven gear meshes with the first gear, and the axial dimension of the driven gear is smaller than the axial dimension of the first gear.

[0022] This application provides a balancing platform. When the rotation axis of the first handwheel is vertically set, the user can horizontally and reciprocally turn the first handwheel. The first handwheel drives the first gear to rotate, which in turn drives the driven gear and the adjustable support legs to rotate synchronously, thereby adjusting the height of the adjustable support legs. Since only the first handwheel needs to be turned, the balancing platform can be leveled with one hand. The operation steps are simple and easy to implement, effectively ensuring the corresponding leveling efficiency and convenience.

[0023] Meanwhile, due to the limited space under the support platform, the first gear is placed below the first handwheel, extending the layout space of the transmission mechanism downwards from the support platform. Furthermore, the axial length of the first gear is greater than that of the driven gear. This not only ensures the stable operation of the transmission mechanism but also helps to improve the ease of its placement under the support platform, further reducing the corresponding production difficulty.

[0024] In some embodiments, the transmission element further includes a second gear;

[0025] The second gear is disposed between the driven gear and the first gear, and meshes with the first gear and the driven gear respectively, and the axial dimension of the driven gear is smaller than the axial dimension of the second gear.

[0026] This application provides a balancing force table with a second gear acting as an idler wheel. On one hand, this changes the rotation direction of the driven gear, aligning it with the rotation direction of the first handwheel, making it easier for the user to understand the leveling process. On the other hand, for different batches of balancing force tables, the adjustable legs are positioned differently below the support platform. By using a second gear of different sizes to link the first and driven gears according to the different leg positions, different spatial layouts can be accommodated. The overall structure is simple and easy to manufacture. Simultaneously, the second gear can absorb speed fluctuations from the first handwheel, making the driven gear run more smoothly and ensuring the stability of the adjustable leg lifting function, thus further promoting cost reduction and efficiency improvement for enterprises.

[0027] In some embodiments, the rotation axis of the adjusting member is horizontal;

[0028] The driven gear includes a worm gear;

[0029] The transmission component includes a worm gear that meshes with the worm wheel; and the end of the worm gear opposite to its helical teeth is coaxially connected to the adjusting component.

[0030] The worm gear is connected to the adjustable support leg via a slide key.

[0031] This application provides a balancing platform that uses a worm gear structure to drive the adjustable feet to rise and fall, so that the direction of the handwheel is aligned with the direction of the feet's rise and fall, making the height adjustment of the feet more intuitive and helping to further improve the user experience.

[0032] In some embodiments, the adjusting element is configured as a second handwheel;

[0033] The end of the worm gear opposite to its helical teeth is coaxially connected to the second handwheel.

[0034] The balancing force table provided in this application can be driven by turning the second handwheel to drive the worm gear structure transmission in practical applications, thereby achieving the leveling of the corresponding balancing force table. The corresponding adjustment component has a simple structure, is easy to produce and operate, and helps to ensure user experience.

[0035] In some embodiments, the adjusting element is configured as a drive gear;

[0036] The transmission component also includes a third gear, which is coaxially connected to the end of the worm gear away from its helical teeth and meshes with the drive gear.

[0037] This application provides a balancing force table with an adjustable drive gear. The drive gear and worm gear are arranged at a right angle, and the direction of drive gear movement is consistent with the lifting direction of the adjustable feet. This makes the height adjustment of the adjustable feet more intuitive and helps to improve the user experience. Simultaneously, a third gear transmission connects the drive gear and the worm gear structure. Adjusting the size of the third gear can meet the spatial layout requirements of the transmission structure of different batches of balancing force tables, helping to reduce the production precision requirements of the balancing force table, improve its production efficiency, and benefit enterprises in terms of energy saving and cost reduction.

[0038] In some embodiments, the outer tooth surface of the worm gear is recessed radially inward to form a limiting groove coaxial with the worm gear;

[0039] The worm gear is adapted to the concave surface of the limiting groove.

[0040] This application provides a balancing force table with a recess on the outer tooth surface of the worm gear, which changes the contact mode of the worm gear from point contact to line contact, improving the reliability of the transmission mechanism, helping to ensure the smooth operation of the adjustable support foot adjustment, thereby improving the product quality of the corresponding balancing force table and enhancing the user experience.

[0041] In some embodiments, the adjustable foot is positioned below the pressure sensor, and the upper end of the adjustable foot is threadedly connected to the pressure sensor.

[0042] On the other hand, this application also provides a balance training device, including any of the balance force platforms described above.

[0043] Compared with the prior art, the balance force table and balance training device provided in this application have at least one of the following advantages:

[0044] 1. This application utilizes a transmission mechanism with corresponding adjustable feet to drive the adjustable feet to vertically raise and lower relative to the support platform, thereby achieving the leveling process of the support platform. An adjusting component, serving as the power input to the transmission mechanism, is installed on the side of the balancing platform. In practical applications, the user observes the placement of the balancing platform and operates the adjusting component to adjust the height of the corresponding adjustable feet to level the platform. Therefore, the leveling process eliminates the need to lift the entire platform and repeatedly twist the feet and test stability. The steps are simple, the operation is convenient, effectively improving the efficiency of the leveling operation and enhancing the user experience.

[0045] 2. In this application, a gear transmission structure is set to drive the rotation of the adjustable support leg. The transmission mechanism can be arranged in various ways, and the structure is simple, convenient for production and assembly, which helps enterprises reduce costs and increase efficiency.

[0061] To more clearly illustrate the technical solutions in the embodiments of this application or the prior art, the specific implementation methods of this application will be described below with reference to the accompanying drawings. Obviously, the accompanying drawings described below are only some embodiments of this application. For those skilled in the art, other drawings and other implementation methods can be obtained based on these drawings without creative effort.

[0062] To keep the drawings concise, each drawing only schematically shows the parts relevant to this application, and they do not represent the actual structure of the product. Furthermore, for ease of understanding, in some drawings, only one of the components with the same structure or function is schematically shown, or only one is labeled. In this document, "one" not only means "only one," but can also mean "more than one."

[0063] In recent years, with the continued growth of the global fitness industry and people's increasing emphasis on healthy living, the market demand for balance training devices has been growing. In related technologies, the balance platform of a balance training device is typically flat, similar to a body fat scale, and mainly includes a support platform, multiple legs, and a pressure sensor array. During training, the user stands on the balance platform and performs corresponding movements according to the prompts. The pressure sensors measure the center of gravity data in real time and feed it back to the processor, which then displays the data on the screen. By observing the corresponding values, the user can understand the user's center of gravity shift and judge their balance ability. In practical applications, due to the unevenness of the ground, the balance training device often shakes after being placed on the ground, affecting the acquisition of center of gravity data, requiring leveling first. Currently, the conventional leveling operation involves lifting the entire balance platform, twisting specific support legs to adjust their height, then placing it back on the ground and testing its stability. Leveling is considered complete once the balance platform is stably placed on the ground. The inventors believe that the conventional leveling method is cumbersome, inefficient, and inconvenient, affecting the user experience.

[0064] In one embodiment, reference is made to the accompanying drawings. Figures 1 to 12 A balancing force table is provided to simplify the corresponding leveling steps and improve the efficiency and convenience of leveling operations. It includes a support platform 1, multiple support legs 2 located below the support platform 1, and pressure sensors 3. The pressure sensors 3 are used to detect the pressure distribution on the support platform 1, and the support legs 2 are used to support the support platform 1. At least one of the support legs 2 includes an adjustable support leg 21, which is vertically adjustable relative to the support platform 1. A transmission structure 4 is also provided below the support platform 1 corresponding to the adjustable support leg 21 to drive the adjustable support leg 21 to rise and fall. Simultaneously, an adjustment component 41 is provided at the power input end of the transmission mechanism 4, and the adjustment component 41 is installed on the side of the support platform 1. Operating the adjustment component 41 drives the transmission mechanism 4 to operate, thereby driving the adjustable support leg 21 to rise and fall relative to the support platform 1, and thus leveling the corresponding balancing force table.

[0065] Since the adjusting component 41 is installed on the side of the balancing platform, in actual application, the user can adjust the height of the corresponding adjustable support leg 21 by operating the adjusting component 41 on the side of the support platform 1 according to the placement of the balancing platform, so as to achieve the leveling of the balancing platform on the ground. The corresponding leveling steps are simple, convenient to operate, and can be completed quickly, effectively improving the user experience.

[0066] In one embodiment, based on the above embodiments, referring to Figures 1 to 12 Specifically, the support platform 1 is roughly rectangular flat plate structure, referring to... Figure 1 and Figure 2In this embodiment, four legs 2 are provided, located at the four corners of the support platform 1; the pressure sensors 3 correspond one-to-one with the legs 2 and are fixed to the support platform 1 with bolts. Of course, the support platform 1 can also be configured in other shapes, such as a circular plate structure, a hexagonal plate structure, etc., as long as it can accommodate the user's body. The number of legs 2 can also be set according to the shape and size of the support platform 1. The shape of the support platform 1, the number of legs 2 and the number of pressure sensors 3 should not be regarded as specific limitations on the scope of protection of this application.

[0067] Reference Figure 2 and Figure 3 In this embodiment, the lower middle part of the support platform 1 is recessed inward to form a receiving cavity 11. The pressure sensor 3, the support leg 2, etc. are all located in the receiving cavity 11 to minimize the influence of dust, water vapor, etc. in the external environment on the pressure sensor 3, the support leg 2 and their connection structure. Of course, in order to ensure the structural strength of the support platform 1, in this embodiment, multiple reinforcing ribs 12 are also arranged crosswise on the lower part of the support platform 1, and each reinforcing rib 12 is located on the bottom wall of the receiving cavity 11.

[0068] Furthermore, refer to Figures 1 to 3 After the lower side of the support platform 1 is recessed, its edge naturally forms a protective edge 13. In this embodiment, any two opposing edges 13 are recessed inward along their own thickness direction to form a gripping part 14, so as to move or reposition the balancing force platform. Of course, the gripping part 14 can also be provided by a subtractive molding method, for example, by laterally hollowing out the edge 13 with a larger thickness. This application does not impose specific limitations on the molding method of the gripping part 14. Meanwhile, referring to Figure 2 Any edge 3 is also formed with a receiving groove 15 to accommodate and avoid the wiring terminals of pressure sensor 3, etc.; in this embodiment, the receiving groove 15 is preferably provided on any edge 13 between the two gripping parts 14.

[0069] Reference Figure 4 A cover plate 5 is also provided below the support platform 1. In this embodiment, the cover plate 5 is preferably slidably embedded in the opening of the receiving cavity 11 along its own thickness direction, and fastened to the support platform 1 by bolts or other fasteners to stably cover the opening of the receiving cavity 11.

[0070] In the embodiments of this application, the transmission mechanism 4 can correspond one-to-one with the support leg 2, that is, the height of any support leg 2 can be adjusted. Of course, only some support legs 2 can be set to be height adjustable. In this embodiment, since there are 4 support legs 2, considering the stability of the triangle, it is preferable to connect the transmission mechanism 4 to one of the support legs 2, that is, only one support leg 2 is set as an adjustable support leg 211. In this embodiment, the upper end of the adjustable support leg 211 is screwed into the corresponding pressure sensor 3. The transmission mechanism 4 drives the adjustable support leg 211 to rotate relative to the pressure sensor 3 around its own axis, which can realize the vertical lifting and lowering drive of the adjustable support leg 211, that is, realize the adjustment of the height of the corresponding adjustable support leg 21.

[0071] Reference Figure 3 In this embodiment, in addition to the adjusting member 41, the transmission mechanism 4 also includes a driven gear 42 and a transmission member 43; wherein, the driven gear 42 is sleeved on the adjustable support leg 21 and is coaxially connected to the adjustable support leg 21; the transmission member 43 is rotatably disposed below the pressure sensor 3 and / or the support platform 1 around its own axis, and is located between the driven gear 42 and the adjusting member 41, so that its power input end is connected to the adjusting member 41 and its power output end is connected to the driven gear 42, thereby realizing the rotation drive of the adjusting member 41 on the adjustable support leg 21.

[0072] Specifically, refer to Figure 2 and Figure 3 When the rotation axis of the adjusting member 41 is vertically arranged, in one embodiment, the adjusting member 41 is set as a first handwheel 411; the transmission member 43 is set as a first gear 431, which is coaxially fixedly connected to the first handwheel 411 and meshes with the driven gear 42. Turning the first handwheel 411 drives the first gear 431 and the driven gear 42 to rotate synchronously, thereby driving the adjustable support leg 21 to rotate. In this embodiment, for ease of assembly, it is preferable that the first gear 431 is coaxially fixed below the first handwheel 411; of course, in the embodiments of this application, a power input gear can also be directly set as the first handwheel 41, or a gear ring can be coaxially sleeved on the outside of the first handwheel 411 to directly mesh with the driven gear 42. The specification of this application is attached. Figure 3 The implementation of a first gear 431 coaxially arranged below the first handwheel 411 is shown, and this embodiment is only described with the transmission component 43 including the first gear 431 as an example.

[0073] Preferably, in this embodiment, the axial length of the driven gear 42 is less than the axial length of the first gear 431, so that while the first gear 431 stably meshes with the driven gear 42, the driven gear 42 can move axially relative to the first gear 431, ensuring that the adjustable support leg 21 can perform vertical lifting and lowering movements. It should be noted that the difference between the axial lengths of the first gear 431 and the driven gear 42 should be greater than the maximum value of the height adjustment range of the adjustable support leg 21.

[0074] Reference Figures 1 to 3 In this embodiment, the first handwheel 411 is preferably provided with anti-slip ridges to reduce the probability of slippage during the leveling process and ensure the stability, reliability and safety of the leveling operation.

[0075] Reference Figure 3 To improve the leveling accuracy, in this embodiment, it is preferable that the radial dimension of the first gear 431 is smaller than that of the driven gear 42; of course, the radial dimension of the first gear 431 can also be set to be smaller than that of the first handwheel 411.

[0076] Furthermore, refer to Figure 4 and Figure 5 In one embodiment, based on the above embodiments, the transmission component 43 preferably further includes a second gear 432. Specifically, the second gear 432 is rotatably positioned below the pressure sensor 3, and is located between the driven gear 42 and the first gear 431, simultaneously meshing with both the first gear 431 and the driven gear 42. This ensures that the rotation direction of the driven gear 42 is consistent with the first handwheel 411, making it easier for the user to clearly understand the leveling process and further improving the user experience. Similarly, preferably, the axial length of the driven gear 42 is less than the axial length of the second gear 432, and the difference in their axial lengths is greater than the maximum value of the height adjustment range of the adjustable foot 21, so that when the adjustable foot 21 is vertically adjusted, the driven gear 42 fitted onto the adjustable foot 21 can always remain meshed with the second gear 432.

[0077] Based on the above embodiments, when the rotation axis of the adjusting member 41 is horizontal, refer to Figures 6 to 10 In one embodiment, the adjusting member 41 is configured as a second handwheel 412; the driven gear is configured as a worm gear 421; correspondingly, the transmission member 43 is configured as a worm 433, with the worm gear 421 meshing with the worm 433, and the end of the worm 433 opposite to its helical teeth being coaxially connected to the second handwheel 412; simultaneously, the worm gear 421 is connected to the adjustable foot 21 via a sliding key 6. Turning the second handwheel 412 drives the worm 433 to operate, thereby causing the adjustable foot 21 to rotate relative to the pressure sensor 3 around its own axis, thus achieving the lifting and lowering drive of the adjustable foot 21.

[0078] Based on the above embodiments, in one embodiment, reference is made to... Figure 11 and Figure 12 Alternatively, the adjusting element 41 can be configured as a drive gear 413, with the end of the worm 433 facing away from its helical teeth coaxially connected to the drive gear 413, so that the worm 433 and the rotation plane of the drive gear 413 are set perpendicularly.

[0079] Of course, in the embodiments of this application, a gear ring can also be coaxially sleeved outside the handwheel structure to form a drive gear 413. This application does not impose specific restrictions on the forming method of the drive gear 413.

[0080] In addition, a third gear 434 can be provided between the worm 433 and the drive gear 413. That is, the transmission component 43 can also include a third gear 434. The end of the worm 433 away from its helical teeth is coaxially connected to the third gear 434, and the third gear 434 meshes with the drive gear 413. At this time, the third gear 434 acts as an idler gear to change the rotation direction of the worm wheel 421 so that the movement direction of the adjustable support 21 is consistent with the turning direction of the drive gear 413, thereby making the leveling effect more intuitive and further ensuring the user experience.

[0081] In this embodiment, the support platform 1 is provided with an ear plate on its lower side, and the drive gear 413 and the third gear 434 are rotatably mounted on the ear plate; by moving the drive gear 413, the adjustable support leg 21 can be driven to rotate relative to the pressure sensor 3, thereby leveling the balance force table.

[0082] In addition, to ensure the transmission stability of the worm gear structure, in this embodiment, it is preferable to set the outer tooth surface of the worm gear 421 to be concave in the radial direction and form a limiting groove that matches the worm gear 421; of course, the limiting groove is coaxially arranged with the worm gear 421.

[0083] In the embodiments of this application, in order to facilitate user operation of the adjustment component 41, a clearance groove 16 is provided on the corresponding side 13 of the support platform 1 to avoid the first handwheel 411, the second handwheel 412 or the drive gear 413; and, depending on the specific arrangement of the transmission mechanism 4, the first handwheel 411, the second handwheel 412 or the drive gear 413 can be at least partially protruding from the corresponding side 13 of the support platform 1, or they can be completely installed in the clearance groove 16.

[0084] The technical solution of this application will be further described in detail below, taking the application of the balance force platform in a balance training scenario as an example. In one embodiment, a balance training device is provided, including the balance force platform described in any of the above embodiments. It may also include a data processing unit and a human-computer interaction system. The human-computer interaction system includes a display screen and a buzzer. The display screen is used to display real-time center of gravity movement data, and the buzzer is used to sound an alarm when the center of gravity exceeds a safe range. The pressure sensor 3, the data processing unit, and the human-computer interaction system are electrically or signal-connected.

[0085] The implementation principle of this embodiment is as follows: When performing static balance training, the user rotates the adjustment component 41 according to the placement of the balance force platform to drive the transmission mechanism 4. The driven gear 42 in the transmission mechanism 4 drives the adjustable support leg 21 to rotate relative to the pressure sensor 3, thereby adjusting the height of the adjustable support leg 21 and thus realizing the leveling process of the balance force platform to ensure that it is placed stably on the ground, effectively reducing the occurrence of training failure due to the shaking of the balance force platform.

[0086] With this leveling structure, the adjusting component 41, which serves as the power input end of the transmission mechanism 4, is located on the side of the support platform 1. The adjusting component 41 is set as a wheel-shaped structure such as a handwheel, allowing the user to perform the leveling operation with one hand. Once the balance force table is observed to be stable, the leveling operation is completed. The leveling operation of the balance force table is convenient and efficient, making the corresponding balance training instrument more convenient to use and effectively ensuring the user experience.

[0087] It should be noted that the above embodiments can be freely combined as needed. The above description is only a preferred embodiment of this application. It should be pointed out that for those skilled in the art, several improvements and modifications can be made without departing from the principle of this application, and these improvements and modifications should also be considered within the protection scope of this application.
