[0044] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the following will, with reference to the accompanying drawings in the embodiments of this application, clearly and completely describe the technical solutions in the embodiments of this application. Obviously, the described embodiments are some but not all of the embodiments of this application. All other embodiments obtained by those of ordinary skill in the art based on the embodiments in this application without creative efforts shall fall within the scope of protection of this application.

[0045] The following disclosure provides many different embodiments or examples for implementing different structures of this application. To simplify the disclosure of this application, components and settings of specific examples are described below. Of course, they are only examples and are not intended to limit this application. In addition, this application may repeat reference numerals and / or letters in different examples. This repetition is for the purpose of simplification and clarity and does not itself indicate the relationship between the various embodiments and / or settings discussed. In addition, this application provides examples of various specific processes and materials, but those of ordinary skill in the art can be aware of the applicability of other processes and / or the use of other materials.

[0046] For ease of description, spatially relative relationship terms may be used in the text to describe the relative positional relationship or movement of one element or feature shown in the figure relative to another element or feature. These relative relationship terms such as "inside", "outside", "inner side", "outer side", "below", "beneath", "above", "over", "front", "rear", etc. This spatially relative relationship term is intended to include different orientations of the device in use or operation other than the orientation depicted in the figure. For example, if the device in the figure undergoes a position flip, attitude change, or motion state change, then these directional indications will change accordingly. For example, an element described as "below other elements or features" or "beneath other elements or features" will then be oriented as "above other elements or features" or "over other elements or features". Therefore, the exemplary term "below" can include both above and below orientations. The device may be oriented otherwise (rotated 90 degrees or in other directions) and the spatially relative relationship descriptors used in the text are interpreted accordingly.

[0047] See Figures 1-5, an embodiment of the present application provides a four - 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 - reduction 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 - reduction 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, and the locking button 200 is fixedly connected to the handrail 400. The locking button 200 can be locked to the sliding guide rail 301.

[0048] Specifically, the preset value of the weight - reduction component offsetting the weight of the handrail 400 can be adjusted according to usage needs. Different structures of the weight - reduction component result in different preset values. The change in the preset value is an interference term for the force on the user's hand. When the weight - reduction component offsets all the gravity of the handrail 400, the user can easily move the handrail 400 up and down.

[0049] Specifically, in the present application, by arranging the mounting rod 300, the upper - limb balance training device and the lower - limb balance training device 100 are integrated, realizing the superposition of the upper - limb and lower - limb training spaces, and greatly saving the floor area of the four - limb balance training system.

[0050] For the four - limb balance training system provided by the present invention, during use, the mounting rod 300 is vertically fixed to the top of the lower - limb balance training device 100, and the handrail 400 is slidably connected to the sliding guide rail 301. When the lower - limb balance training device 100 is not needed, the locking button 200 cannot be 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 training. At the same time, the preset value of the weight of the handrail 400 can be offset by the weight - reduction component, thereby interfering with the force on the user's hand. When the lower - limb balance training device 100 is needed, 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. By integrating the lower - limb balance training device 100 and the upper - limb balance training device in the present application, the balance training of the upper limb and the lower limb can be carried out using one four - limb balance training system, thereby improving the user's convenience of use. By setting the weight - reduction component, the gravity of the handrail 400 can be offset, thus interfering with the user and improving the balance training effect. When using the lower - limb balance training device 100, the fixed handrail 400 can also protect the user, thereby improving the safety of the four - limb balance training system.

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

[0052] Specifically, the first handrail 401 and the second handrail 402 are respectively used to support the left hand and the right hand, 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 handrail 400 can be changed, so as to be suitable for users of different heights.

[0054] Specifically, the following 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 grasping force distribution of the user in real time.

[0055] When in use, slide the handrail 400 up and down along the sliding guide rail 301 to the shoulder height position. The user can act on the first handrail 401 or the second handrail 402 with one hand for alternating weight-bearing training, or act on the first handrail 401 and the second handrail 402 with both hands to move the handrails up and down for 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. The user can replace the first handrail 401 and the second handrail 402 with different shapes according to the usage needs, so as to change the holding direction of the hand and stimulate muscle groups at different positions.

[0057] Furthermore, the connecting rod can be a telescopic rod, which can extend and retract in the horizontal direction to adjust the distance between the first handrail 401 and the second handrail 402, so that the four-limb balance training system can be suitable for users with different shoulder widths.

[0058] Such an arrangement enables the four-limb balance training system to be applied to different populations, thereby expanding the applicable range of the four-limb balance training system.

[0059] To optimize the above technical solution, the four-limb balance training system further includes a controller. The sliding guide rail 301 is provided with a locking hole 303. The locking button 200 is fixedly connected to the slider 302, and 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 the working state, the controller controls the locking button 200 to cooperate with the locking hole 303, and the slider 302 is fixed on the sliding guide rail 301. When the upper limb balance training device is in the working state, 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, and its specific structure includes an electromagnetic coil, an armature slider cooperating with the locking hole 303, and a return spring. When the lower limb balance training device 100 is started, the controller sends a signal to the electromagnetic coil to generate a magnetic attraction force, and the armature slider is inserted into the locking hole 303, thereby completely restricting the sliding of the slider 302 along the sliding guide 301; when the upper limb balance training device is started, the electromagnetic coil is powered off, the magnetic force disappears, and the return spring pulls the armature slider back to its original position, no longer restricting the sliding of the slider 302 along the sliding guide 301.

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

[0062] In other embodiments, a manual knob can be provided to mechanically lock the slider 302 and the sliding guide 301 through a threaded pair.

[0063] The above two embodiments are both alternative solutions to the electromagnetic lock. When the electromagnetic lock fails, the user can manually fix the armrest 400.

[0064] Such an arrangement can achieve rapid switching between upper limb training and lower limb training, ensure the effective positioning of the armrest 400, and thus improve the usability and safety of the four-limb balance training system.

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

[0066] Specifically, the rotary bearing 700 can adopt a double-row angular contact ball bearing, the inner ring of which is in interference fit with the first connecting plate 501 of the connecting member 500, and the outer ring of which is bolt-fixed to the slider 302. During use, when the user's hand acts on the armrest 400, when performing push-pull training, it is necessary to overcome the resistance of the weight reduction component in the vertical direction and the rotational resistance moment in the horizontal plane. Since the rotary bearing 700 provides the rotational freedom of the armrest 400, it will interfere with the user and increase the training complexity, thus being beneficial to improving the user's muscle coordination and enhancing the balance training effect.

[0067] Further, a limiting member can be provided on the slider 302 or the first connecting plate 501 according to the use requirements to limit the rotation angle of the rotary bearing 700, so as to meet the use requirements of different rehabilitation stages of the user.

[0068] To optimize the above technical solution, the four-limb balance training system further includes a second connecting plate 502, which is horizontally arranged, 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 member 600. The pulley 601 is arranged on the second side of the second connecting plate 502. The steel cable 602 cooperates with the pulley 601, and the steel cable 602 is used to connect the armrest 400 and the weight reduction member 600.

[0069] Specifically, the steel cable 602 passes through the pulley 601 and is respectively connected to the armrest 400 and the weight reduction member 600. By setting a driving member such as a motor to act on the weight reduction member 600, a part of the gravity of the armrest 400 can be offset, thereby changing the force required for the user to move the armrest 400 by hand, forming an interference item for the user, and thus performing upper limb balance training.

[0070] Specifically, the second connecting plate 502 mainly plays a supporting and connecting role, 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 reduction member 600 is a spring or a counterweight.

[0072] When the weight reduction member 600 is a spring, it is preferably a gas spring. Cooperating with an electric cylinder, the gas spring and the armrest 400 are connected by the steel cable 602, and the gravity of the armrest 400 is converted into the thrust of the gas spring, thereby realizing the weight reduction of the armrest 400. That is, the high-pressure gas inside the gas spring generates a constant thrust through the piston, which balances the gravity of the armrest 400. The motor drives the lead screw to dynamically adjust the thrust size, artificially creating an unstable state, forcing the user to continuously adjust the force, thereby forming an interference item for the force required for the user to push the armrest 400, being able to adapt to different training needs of the user, and improving the upper limb balance training effect.

[0073] When the weight reduction member 600 is a counterweight, the counterweight directly balances the gravity of the armrest 400 through the pulley 601. That is, by changing the weight of the counterweight, the magnitude of the force required for the user to push the armrest 400 is changed, thereby adapting to different training needs of the user and improving the upper limb balance training effect.

[0074] Both types of weight reduction members 600 can achieve the purpose of reducing the weight of the armrest 400. When the user pushes the armrest 400, only the remaining gravity (such as 30% of the original weight) needs to be overcome, which is suitable for patients with weaker muscle strength. The manufacturer can select different weight reduction members 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 perpendicular to the mounting rod 300, and the fixing part 102 is provided with a plug hole. The second end of the mounting rod 300 is inserted into the lower limb balance training device 100 through the plug hole.

[0076] Specifically, the mounting rod 300 can be a telescopic rod. The height of the mounting rod 300 can be changed by using 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 plug hole.

[0079] Specifically, the steel cable 602 and the weight reduction part 600 are arranged inside the mounting rod 300. When the weight reduction part 600 is a counterweight block, a hatch is opened at the second end of the mounting rod 300 to facilitate the replacement of the counterweight block.

[0080] During use, the second end of the mounting rod 300 is inserted into the lower limb balance training device 100 through the plug hole, so that the lower limb balance training device 100 and the upper limb balance training device are integrated into a four-limb balance training system. The user can replace any training device to be in a working state according to the usage needs, thereby expanding the applicable range of the four-limb balance training system and improving the user's convenience of use. When not in use, only by pulling out the second end of the mounting rod 300, the lower limb balance training device 100 and the upper limb balance training device can be stored separately, 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 body and a second rod body. A sliding guide rail 301 is connected to the first end of the first rod body. The second end of the first rod body is hinged to the first end of the second rod body. The second end of the second rod body is fixedly connected to the fixing part 102. When the first rod body and the second rod body are arranged perpendicular to each other, the upper limb balance training device is folded and arranged above the lower limb balance training device 100.

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

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

[0084] Such an arrangement can ensure the structural integrity of the four-limb balance training system and improve the user's convenience of use.

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

[0086] Specifically, when the controller issues a locking signal, the driving locking button 200 is connected to the locking hole 303 closest to it to achieve rapid positioning of the armrest 400.

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

[0088] To optimize the above technical solution, the four-limb balance training system further includes a display 800 and a force sensor. The display 800 is arranged at the first end of the mounting rod 300 and is electrically connected to the controller for displaying the working states 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 acting force on the armrest 400 exceeds a preset value, it transmits the acting force data to the controller, and the controller controls the locking button 200 to be locked on the sliding guide rail 301.

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

[0090] Specifically, the display 800 is used to display the working states 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 duration of the lower-limb balance training device 100 and the upper-limb balance training device, so that the user can obtain training data, correspondingly adjust the training items, and improve the application efficiency of the four-limb balance training system.

[0091] It should be noted that the four - limb balance training system provided by the present invention can be used in the technical field of rehabilitation equipment or other fields. The other fields refer to any fields other than the technical field of rehabilitation equipment. The above is only an example and does not limit the application fields of the four - limb balance training system provided by the present invention.
