[0002] Balance control is a complex motor skill; walking, standing, and various other movements all rely on proper balance to be performed smoothly. Maintaining postural balance is a complex process that depends on the coordination of visual, proprioceptive, and vestibular information by the central nervous system and the control of motor effectors. These elements are indispensable and interdependent. With the increasing annual incidence of cerebrovascular diseases, Parkinson's disease, traumatic brain injury, and spinal cord injury, these diseases and injuries can cause balance dysfunction and even disability. Balance dysfunction is a major contributing factor to disability. Multiple medical studies have shown that training, including balance function and upper and lower limb function, is an important way to improve function.

[0044] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0045] The following disclosure provides numerous different embodiments or examples for implementing various structures of this application. To simplify the disclosure, specific examples of components and arrangements are described below. These are merely examples and are not intended to limit the scope of this application. Furthermore, reference numerals and / or letters may be repeated in different examples. Such repetition is for simplification and clarity and does not in itself indicate a relationship between the various embodiments and / or arrangements discussed. In addition, various specific examples of processes and materials are provided in this application; however, those skilled in the art will recognize the applicability of other processes and / or the use of other materials.

[0046] For ease of description, spatial relative terms may be used in the text to describe the relative position or movement of one element or feature relative to another element or feature, as shown in the figure. These relative terms include, for example, "inside," "outside," "middle," "outer," "below," "below," "above," "front," "back," etc. Such spatial relative terms are intended to include different orientations of the device in use or operation, other than those depicted in the figure. For example, if the device in the figure undergoes a positional flip, orientation change, or change of motion, these directional indications will change accordingly. For instance, an element described as "below other elements or features" or "below other elements or features" will subsequently be oriented "above other elements or features" or "above other elements or features." Therefore, the example term "below" can include both upper and lower orientations. The device may be otherwise oriented (rotated 90 degrees or in other directions), and the spatial relative descriptors used in the text will be interpreted accordingly.

[0047] See Figures 1-5This application provides a limb balance training system, including a lower limb balance training device 100, an upper limb balance training device, and a locking button 200. The upper limb balance training device includes a mounting rod 300, a sliding guide rail 301, a handrail 400, and a weight-reducing component. The sliding guide rail 301 is connected to the first end of the mounting rod 300 and extends along the axial direction of the mounting rod 300. The mounting rod 300 is arranged perpendicular to the lower limb balance training device 100, and the second end of the mounting rod 300 is connected to the lower limb balance training device 100. The weight-reducing component is connected to the handrail 400 and is used to offset a preset value of the weight of the handrail 400. The handrail 400 is slidably connected to the sliding guide rail 301. The locking button 200 is fixedly connected to the handrail 400 and can be locked to the sliding guide rail 301.

[0048] Specifically, the preset value of the weight-reducing components offsetting the weight of the handrail 400 can be adjusted according to usage needs. Different structures of the weight-reducing components result in different preset values. Changes in the preset values ​​affect the force exerted on the user's hands. When the weight-reducing components offset the entire weight of the handrail 400, the user can easily move the handrail 400 up and down.

[0049] Specifically, this application integrates an upper limb balance training device and a lower limb balance training device 100 by arranging an installation rod 300, thereby achieving the superposition of upper and lower limb training spaces and greatly saving the floor space occupied by the limb balance training system.

[0050] The limb balance training system provided by this utility model involves vertically fixing the mounting rod 300 to the top of the lower limb balance training device 100 during use, and slidably connecting the handrail 400 to the sliding guide rail 301. When the lower limb balance training device 100 is not needed, the locking button 200 is not locked to the sliding guide rail 301, and the handrail 400 can move up and down along the sliding guide rail 301. The user can freely push the handrail 400 for lifting and lowering training. At the same time, the preset weight of the handrail 400 can be offset by the weight-reducing component, thereby interfering with the force on the user's hands. When the lower limb balance training device 100 needs to be used, the locking button 200 is locked to the sliding guide rail 301, and the handrail 400 cannot move up and down along the sliding guide rail 301. This application integrates a lower limb balance training device 100 and an upper limb balance training device, enabling balance training of the upper and lower limbs to be conducted using a single four-limb balance training system. This improves user convenience. By incorporating weight-reducing components, the weight of the handrail 400 can be counteracted, thereby reducing interference with the user and enhancing the balance training effect. Furthermore, when using the lower limb balance training device 100, the fixed handrail 400 also provides protection for the user, thus improving the safety of the four-limb balance training system.

[0051] To optimize the above technical solution, the limb balance training system also includes a slider 302 and a U-shaped handrail 400, which includes a first handrail 401, a connecting rod, and a second handrail 402. The connecting rod is connected to the slider 302, and the first handrail 401 and the second handrail 402 are set horizontally to support the upper limbs.

[0052] Specifically, the first handrail 401 and the second handrail 402 are used to support the left and right hands respectively, and the handrail 400 has a symmetrical structure.

[0053] Specifically, by adjusting the locking button 200 to lock the position on the sliding guide rail 301, the height of the armrest 400 can be changed to suit users of different heights.

[0054] Specifically, force sensors (including but not limited to piezoelectric film sensors) can be integrated on the surfaces of the first handrail 401 and the second handrail 402 to monitor the distribution of the user's gripping force in real time.

[0055] When in use, slide the handrail 400 up and down along the sliding guide rail 301 to shoulder height. The user can use one hand to apply the first handrail 401 or the second handrail 402 to perform alternating weight-bearing training, or use both hands to apply the first handrail 401 and the second handrail 402 to move the handrails up and down and perform weight-bearing training with both hands at the same time.

[0056] Furthermore, the first handrail 401 and the second handrail 402 can be detachably connected to the connecting rod. Users can replace the first handrail 401 and the second handrail 402 with different shapes according to their needs, thereby changing the grip direction of the hand and stimulating muscle groups in different positions.

[0057] Furthermore, the connecting rod can be a telescopic rod that can extend and retract horizontally to adjust the distance between the first support bar 401 and the second support bar 402, thereby making the limb balance training system suitable for users with different shoulder widths.

[0058] This arrangement allows the limb balance training system to be applied to different groups of people, thereby expanding the scope of application of the limb balance training system.

[0059] To optimize the above technical solution, the limb balance training system also includes a controller. The sliding guide rail 301 has a locking hole 303. The locking button 200 is fixedly connected to the slider 302. The locking button 200, the upper limb balance training device, and the lower limb balance training device 100 are electrically connected to the controller. When the lower limb balance training device 100 is in working condition, the controller controls the locking button 200 to cooperate with the locking hole 303, and the slider 302 is fixed to the sliding guide rail 301. When the upper limb balance training device is in working condition, the controller controls the locking button 200 to separate from the locking hole 303, and the slider 302 can slide along the sliding guide rail 301.

[0060] Specifically, the locking button 200 can be an electromagnetic lock, the specific structure of which includes an electromagnetic coil, an armature sliding block that cooperates with the locking hole 303, and a return spring. When the lower limb balance training device 100 is activated, the controller sends a signal to the electromagnetic coil, generating a magnetic attraction force, and the armature sliding block is inserted into the locking hole 303, thereby completely restricting the sliding of the slider 302 along the sliding guide rail 301; when the upper limb balance training device is activated, the electromagnetic coil is de-energized, the magnetic force disappears, and the return spring pulls the armature sliding block back to its original position, no longer restricting the sliding of the slider 302 along the sliding guide rail 301.

[0061] In some embodiments, the limb balance training system may further include an elastic positioning pin, which is disposed on the slider 302 and can be manually inserted into the locking hole 303 to achieve quick fixation of the handrail 400.

[0062] In other embodiments, a manual knob may be provided to connect the threaded pair mechanical locking slider 302 and the sliding guide rail 301.

[0063] Both of the above embodiments are alternatives to electromagnetic locks. When the electromagnetic lock malfunctions, the user can manually fix the handrail 400.

[0064] This arrangement allows for quick switching between upper and lower limb training, ensuring the effective positioning of the handrail 400, thereby improving the ease of use and safety of the limb balance training system.

[0065] To optimize the above technical solution, the limb balance training system also includes a connector 500 and a rotary bearing 700. The connector 500 is U-shaped and includes a first mounting plate, a first connecting plate 501, and a second mounting plate. The first mounting plate is connected to the first handrail 401, and the second mounting plate is connected to the second handrail 402. The first connecting plate 501 is connected to the slider 302 through the rotary bearing 700, which can rotate around its own axis.

[0066] Specifically, the rotary bearing 700 can be a double-row angular contact ball bearing, with its inner ring interference-fitted with the first connecting plate 501 of the connecting member 500, and its outer ring bolted to the slider 302. During use, the user's hands act on the handle 400. When performing push-pull training, the user needs to overcome the resistance of the vertical weight-reducing components and the rotational resistance torque in the horizontal plane. Because the rotary bearing 700 provides rotational freedom for the handle 400, it interferes with the user's movements, increasing the complexity of the training. However, this also helps improve the user's muscle coordination and balance training effectiveness.

[0067] Furthermore, limiting elements can be provided on the slider 302 or the first connecting plate 501 as needed to limit the rotation angle of the rotary bearing 700, thereby adapting to the user's needs at different rehabilitation stages.

[0068] To optimize the above technical solution, the limb balance training system also includes a second connecting plate 502. The second connecting plate 502 is arranged horizontally, and the first side of the second connecting plate 502 is connected to the sliding guide rail 301 and the first end of the mounting rod 300. The weight reduction component includes a pulley 601, a steel cable 602 and a weight reduction element 600. The pulley 601 is located on the second side of the second connecting plate 502, and the steel cable 602 cooperates with the pulley 601. The steel cable 602 is used to connect the handrail 400 and the weight reduction element 600.

[0069] Specifically, the steel cable 602 passes through the pulley 601 and connects the handrail 400 and the weight-reducing component 600 respectively. By setting a motor or other driving component to act on the weight-reducing component 600, part of the weight of the handrail 400 can be offset, thereby changing the force required for the hand to move the handrail 400, forming an interference item for the user, and thus conducting upper limb balance training.

[0070] Specifically, the second connecting plate 502 mainly serves as a support and connection, and through holes for the steel cable 602 to pass through can be provided on the second connecting plate 502.

[0071] To optimize the above technical solution, the weight-reducing component 600 is a spring or a counterweight.

[0072] When the weight-reducing component 600 is a spring, a gas spring is preferred. In conjunction with an electric cylinder, the gas spring and handrail 400 are connected by a steel cable 602. This converts the weight of the handrail 400 into the thrust of the gas spring, thus reducing the weight of the handrail 400. Specifically, the high-pressure gas inside the gas spring generates a constant thrust through a piston, balancing the weight of the handrail 400. A motor drives a lead screw to dynamically adjust the thrust, artificially creating an unstable state that forces the user to continuously adjust their force. This creates an interference factor, allowing the user to adapt to different training needs and improve the effectiveness of upper limb balance training.

[0073] When the weight-reducing component 600 is a counterweight, the counterweight directly balances the weight of the handrail 400 through the pulley 601. That is, by changing the weight of the counterweight, the amount of force required for the user to push the handrail 400 is changed, thereby adapting to the user's different training needs and improving the effect of upper limb balance training.

[0074] Both types of weight-reducing components 600 can achieve the purpose of weight-reducing handrails 400. When users push handrails 400, they only need to overcome the remaining gravity (such as 30% of the original weight), which is suitable for patients with weak muscle strength. Manufacturers can choose different weight-reducing components 600 according to production costs and training goals.

[0075] To optimize the above technical solution, the lower limb balance training device 100 includes a trainer body 101 and a fixing part 102. The fixing part 102 is connected to the trainer body 101 and is used to connect the second end of the mounting rod 300. The fixing part 102 is arranged perpendicularly to the mounting rod 300, and the fixing part 102 has a plug-in hole. The second end of the mounting rod 300 is plugged into the lower limb balance training device 100 through the plug-in hole.

[0076] Specifically, the mounting rod 300 can be a telescopic rod, and the height of the mounting rod 300 can be changed by using a sleeve thread connection or by using a positioning pin.

[0077] Specifically, the mounting rod 300 can be a rod with a fixed height.

[0078] Specifically, the fixing part 102 is square to facilitate the opening of the insertion hole.

[0079] Specifically, the steel cable 602 and the weight-reducing component 600 are located inside the mounting rod 300. When the weight-reducing component 600 is a counterweight, a hatch is provided at the second end of the mounting rod 300 to facilitate the replacement of the counterweight.

[0080] In use, the second end of the mounting rod 300 is inserted into the lower limb balance training device 100 through a connector hole, integrating the lower limb balance training device 100 and the upper limb balance training device into a four-limb balance training system. Users can switch either training device to be in operation as needed, thus expanding the applicability of the four-limb balance training system and improving user convenience. When not in use, simply pulling out the second end of the mounting rod 300 allows for the separate storage of the lower limb balance training device 100 and the upper limb balance training device, reducing the storage space occupied by the four-limb balance training system.

[0081] To optimize the above technical solution, the lower limb balance training device 100 includes a trainer body 101 and a fixing part 102. The fixing part 102 is connected to the trainer body 101. The mounting rod 300 includes a first rod and a second rod. The sliding guide rail 301 is connected to the first end of the first rod. The second end of the first rod is hinged to the first end of the second rod. The second end of the second rod is fixedly connected to the fixing part 102. When the first rod and the second rod are arranged perpendicularly, the upper limb balance training device is folded and arranged above the lower limb balance training device 100.

[0082] Specifically, the first rod and the second rod can be hinged together using components such as a hinge shaft or a sleeve.

[0083] Specifically, a folding locking pin and a locking groove can be provided on the first rod and the second rod. When the folding locking pin and the locking groove are engaged, the first rod and the second rod are in a folded and locked state. The first rod is laid down to a horizontal position for easy storage and transportation. When the folding locking pin and the locking groove are separated, the first end of the first rod can gradually move away from the second rod until the two are on the same vertical line.

[0084] This arrangement ensures the structural integrity of the limb balance training system and improves user convenience.

[0085] To optimize the above technical solution, the locking holes 303 are distributed at equal intervals of 50mm along the length of the sliding guide rail 301.

[0086] Specifically, when the controller sends a locking signal, it drives the locking button 200 to connect to the nearest locking hole 303 to achieve rapid positioning of the handrail 400.

[0087] During use, the locking button 200 can be fixed to the appropriate locking hole 303 according to training needs or the user's shoulder height, thereby improving training accuracy.

[0088] To optimize the above technical solution, the limb balance training system also includes a display 800 and a force sensor. The display 800 is located at the first end of the mounting rod 300 and is electrically connected to the controller. It is used to display the working status of the lower limb balance training device 100, the upper limb balance training device and the locking button 200. The force sensor is electrically connected to the controller. When the force sensor detects that the force of the handrail 400 exceeds the preset value, it transmits the force data to the controller. The controller controls the locking button 200 to lock in the sliding guide rail 301.

[0089] Specifically, when the force sensor detects that the force applied to the handrail 400 exceeds the preset value, it indicates that the user's hand force is unbalanced. At this time, the force sensor transmits the force data to the controller, and the controller controls the locking button 200 to lock onto the sliding guide rail 301, so that the handrail 400 can be quickly positioned and the user can hold onto the handrail 400 to prevent falling, thereby improving the safety of the user when using the limb balance training system.

[0090] Specifically, the display 800 is used to display the working status of the lower limb balance training device 100, the upper limb balance training device and the locking button 200, and can also display the application time of the lower limb balance training device 100 and the upper limb balance training device, so that users can obtain training data, adjust training items accordingly, and improve the application efficiency of the limb balance training system.

Other fields refer to any field other than the field of rehabilitation equipment technology.
