[0016] Advantages of the present invention compared with the prior art:

[0017] 1. This bipedal balance rehabilitation training device completes a smooth transition from static balance to dynamic strengthening training through a dual-mode training mechanism: in the initial stage, patients can use the horizontally placed foot box for foot drop correction training, and in the later stage, the foot strength is enhanced by switching to the alternating stepping mode, realizing a stepped adaptation of the rehabilitation process.

[0018] 2. This bipedal balance rehabilitation training device completes a rapid switching of training modes through the linkage design of the deflection block supporting structure and the ball valve: rotating the adjusting rod drives the ball valve to control the on-off of the liquid storage pipe, and synchronously links the deflection block to limit or release the foot box, enabling the device to flexibly switch between static balance maintenance and dynamic alternating stepping, with convenient operation and high stability.

[0019] 3. This bipedal balance rehabilitation training device achieves an adaptive adjustment effect of the upward tilt angle of the foot through the hinged downward turning of the foot box and the hydraulic damping system: when stepping on it, the pressure liquid rod squeezes the damping liquid and transfers it to the liquid storage bladder, forming a progressive resistance, which not only avoids joint impact damage but also enhances proprioceptive training through hydraulic feedback.

[0020] 4. This bipedal balance rehabilitation training device ensures precise and controllable mechanical transmission during alternating training through the limit of the stop bar and the one-way connection design of the liquid storage pipe: when one side of the foot box turns downward, the other side remains stable due to the block of the stop bar and hydraulic blockage, preventing ineffective liquid leakage, and realizing the coherence and safety of the alternating center of gravity transfer of both feet.

[0021] 5. This bipedal balance rehabilitation training device integrates two functional modules, namely a trainer and an adjustment group, through the box-type inclined opening structure of the training seat, achieving miniaturization of the device and adaptability to the training scenario: the compact layout reduces the space requirement for use, and at the same time, the inclined opening facilitates the switching between sitting and standing postures for patients, improving the human-computer interaction experience of rehabilitation training.

They are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and thus cannot be understood as a limitation of the present invention. In addition, in the description of the present invention, the meaning of "several" is two or more, unless otherwise clearly and specifically defined.

[0040] Please refer to Figures 1 - 11 As shown, the present invention provides a bipedal balance rehabilitation training device, which includes a training seat 100 with a box-shaped inclined opening. Inside the training seat 100, there are a pair of trainers 200 for bipedal balance standing and an adjustment group 300 for switching the trainers 200 to alternate stepping; as Figures 2 - 4 As shown, this device has two training modes. One is to stand on the trainers 200 with both feet to maintain balance training, and the other is to change the alternating movement of the trainers 200 through the adjustment group 300, so that when maintaining balance with both feet, the training intensity is increased to promote rehabilitation.

[0041] Specifically, as Figures 5 - 7 As shown, the trainer 200 includes a foot placement box 210 rotatably connected to the inner wall of the front end of the training seat 100 and a foot pedal 220 that is adaptively clamped and flipped with the top port of the foot placement box 210; on the bottom surface of the rear end of the training seat 100, there are symmetrically arranged limit blocks 120 for supporting the foot placement box 210, so that the foot placement box 210 remains horizontal to support the bipedal standing balance training; a positioning hole 211 is opened on the middle side wall of the foot placement box 210 and near the front end of the training seat 100, and a positioning rod 221 is inserted at the position corresponding to the positioning hole 211 on the bottom surface of the foot pedal 220. When the foot stands on the foot pedal 220, the foot forms an upwardly tilted state; since both the positioning hole 211 and the positioning rod 221 are close to the front end of the foot placement box 210, the center of gravity of both feet is located at the rear section of the foot pedal 220, and the upwardly tilted posture of the foot is maintained. The balance training in this posture is used to overcome foot drop and restore the normal posture of the foot.

[0042] Further, a rotation hole 212 is formed in the front side wall of the foot placement box 210, and a jack 102 is formed in the front side wall of the training seat 100. The foot placement box 210 and the training seat 100 are rotationally connected by inserting a rotating shaft 140 into the jack 102 and the rotation hole 212; two pairs of annular grooves are formed on the rotating shaft 140, and the distance between each pair of annular grooves is equal to the width of the foot placement box 210. The foot placement box 210 is limited by buckling a snap ring on the annular groove.

[0043] Further, the front bottom surface of the foot pedal 220 is fixedly connected to a weight increasing block 222 by bolts, that is, a metal block with weight, and its weight is used to drive the foot pedal 220 to reset and keep horizontal for the next stable standing of both feet; a silica gel pad is bonded to the bottom surface of the weight increasing block 222 to eliminate the impact sound of the foot pedal 220 rotating and resetting; a stop block 230 is embedded in the top surface of the rear end of the foot pedal 220. The stop block 230 is in the shape of an arc plate and a silica gel pad is bonded to the inner side for supporting the rear heel. At the same time, the foot pedal 220 is a plastic part and a plurality of convex strips are arranged at equal intervals on its top surface to play an anti-slip role; a slot 223 for inserting the bottom of the stop block 230 is formed in the top surface of the rear end of the foot pedal 220 for easy disassembly and assembly of the stop block 230 for cleaning or replacement.

[0044] In addition, arc grooves 101 are symmetrically formed in the left and right side walls of the training seat 100. The arc grooves 101 coincide with the central axis of the jack 102. A sliding column 213 slidably inserted into the arc groove 101 is arranged on the rearwardly offset side wall of the foot placement box 210, so that the foot placement box 210 is stably deflected around the rotating shaft 140.

[0045] Specifically, as Figure 6 and Figures 10 - 11 shown, a retaining platform 103 is arranged inside the front end of the training seat 100 and above the jack 102 for blocking the upward turning of the foot placement box 210. The limiting block 120 has a frustum of a cone structure and through grooves 121 are formed through its front and rear surfaces. A deflecting block 130 is rotatably connected inside the through grooves 121. Fixed angle blocks 122 for blocking the rotation angle of the deflecting block 130 are arranged on the front and rear sides of the deflecting block 130. The upper end of the deflecting block 130 turns out in front of the upper port of the through groove 121 to support the foot placement box 210, so that the foot placement box 210 is kept horizontal for the standing training of both feet. Three through holes 125 are symmetrically formed in the inner side wall of the bottom of the through groove 121. The through hole 125 in the middle corresponds to the central hole of the deflecting block 130 and is connected by a pin. The central angle of the deflecting block 130 is smaller than the included angle between the two fixed angle blocks 122, so that the deflecting block 130 deflects and adjusts back and forth; the other two through holes 125 are connected through the side walls of the two fixed angle blocks 122 by pins to fixedly support and block the deflecting block 130.

[0046] Further, a card slot 123 is provided at the bottom center line of the limit block 120. Symmetrically, limit bars 150 are fixedly connected to the bottom surface at the rear end of the training seat 100 through bolts. The limit bars 150 are inserted and matched with the card slot 123, so that the limit block 120 will not slide back and forth; on the front and rear side walls of the deflection block 130, there are retaining bars 131 for lapping on the top of the fixed angle block 122, which further increases the strength of the deflection block 130 supporting the foot box 210. Moreover, the design of the retaining bars 131 also facilitates pinching with fingers to pull the deflection block 130 to rotate and adjust to form a state of supporting the foot box 210 and a state of removing the limit.

[0047] Further, on the front and rear sides of the bottom of the limit block 120, there are symmetrically provided support platforms 124 for blocking the foot box 210 after it is turned down, so as to control the flipping angle; on the outer wall at the front end of the training seat 100, there is fixedly connected an armrest 110 with a telescopic function, that is, the inner and outer tubes are sleeved to adjust the telescopic height of the support, and the height can be positioned by tightening the bolts.

[0048] Specifically, as Figure 8 and Figure 9 shown, the adjustment group 300 includes a pair of liquid storage tubes 310 in a bent state, an adjustment rod 320 for adjusting the opening and closing of the proximal ends of the pair of liquid storage tubes 310, and a liquid pressing rod 330 adaptively inserted into the rear end of the liquid storage tube 310; the liquid storage tube 310 is filled with damping liquid. At the bottom end of the adjustment rod 320, a ball valve 321 for blocking the pipe orifice of the liquid storage tube 310 is tightly sleeved. On the left and right half side walls of the ball valve 321, there are symmetrically provided flow holes 322 for communicating with the liquid storage tube 310. By rotating the adjustment rod 320, the ball valve 321 is driven to switch between blocking and communicating the pair of liquid storage tubes 310. When blocked, the two feet stand steadily for training; when communicated, the two feet alternately switch the center of gravity to step on the two foot boxes 210 for turning down to enhance the foot strength training.

[0049] Among them, the front ends of a pair of liquid storage tubes 310 face each other and are sleeved with a connecting tube 312. The middle part of the connecting tube 312 is sleeved with a liquid storage bladder 313 through a thin tube. The liquid storage bladder 313 is made of silica gel or rubber and is in a spherical shape. The liquid storage bladder 313 expands to store the damping liquid and contracts to extrude the damping liquid into the liquid storage tube 310 for temporarily storing the damping liquid. The flow hole 322 is a T-shaped three-way hole. The two coaxially arranged holes penetrate through the front and rear walls of the ball valve 321. A sealing ring is embedded in the midline of the front and rear walls of the ball valve 321 to separate the two flow holes 322. The third hole of the flow hole 322 on the left penetrates through the center of the left side wall of the ball valve 321. When all three holes of the flow hole 322 are located at the port of one liquid storage tube 310, the sealing ring is used to seal the thin tube orifice of the liquid storage bladder 313, and then the two liquid storage tubes 310 are in an entirely blocked state. When the third hole of the flow hole 322 turns towards the liquid storage bladder 313, the two liquid storage tubes 310 are in a connected state. The diameter of the ball valve 321 is equal to the inner diameter of the connecting tube 312. The adjusting rod 320 penetrates through the front top surface of the training seat 100 and passes through the top of the connecting tube 312 and is tightly inserted into the center of the ball valve 321.

[0050] Furthermore, the rear end of the liquid storage tube 310 is provided with an upwardly curved arc tube 311, and the central axis of the arc tube 311 coincides with the rotation central axis of the footrest box 210. The liquid pressing rod 330 is adaptively inserted into the arc tube 311, and the upper end of the liquid pressing rod 330 is fixedly connected to the side wall of the footrest box 210. A plug post 214 is embedded in the rear side wall of the footrest box 210, and the plug post 214 penetrates through the upper side wall of the liquid pressing rod 330, so that when one footrest box 210 is stepped on and turned downwards, the liquid pressing rod 330 can be smoothly extruded into the liquid storage tube 310, and the damping liquid in this liquid storage tube 310 is transferred to the liquid storage bladder 313, playing a role in temporarily storing and converting the damping liquid. At the same time, due to the blocking of the blocking platform 103, the other footrest box 210 cannot be turned upwards, and the damping liquid will not leak out from the other liquid storage tube 310.

[0051] Furthermore, the rearward horizontal bending section of the liquid storage tube 310 is laid along the inner side of the training seat 100 and is fixed by a pipe clamp. The setting of the support platform 124 enables the footrest box 210 to stop above the liquid storage tube 310 when it is turned downwards. The top end of the adjusting rod 320 is clamped with a lever 340. The direction of the lever 340 is consistent with the orientation of the flow hole 322, that is, the lever 340 points rearward. Both ends of the flow hole 322 are located in one liquid storage tube 310, and the lever 340 points left and right, thus clearly indicating that the ball valve 321 is in a state of connecting the two liquid storage tubes 310 and the liquid storage bladder 313, so as to facilitate the smooth flow of the damping liquid when the footrest box 210 moves and cooperate with its movement.

[0052] When the bipedal balance rehabilitation training device of the present invention is in use, it has two training modes. One is to stand on both feet in the trainer 200 to maintain balance training; turn the deflection block 130 to the lower part of the rear end of the foot placement box 210 for support, so that the foot placement box 210 is kept in a horizontal state. At this time, when both feet stand on the foot pedal 220, the heels of the feet step on the foot pedal 220 and turn down, forming a state of the feet turning up; the balance training in this posture is used to overcome foot drop and restore the normal walking posture of the feet.

[0053] The other is to increase the training intensity while maintaining balance on both feet; by turning the deflection block 130 to remove the support limit for the foot placement box 210, when both feet stand on the foot placement box 210, it can descend and rotate, increasing the angle of the feet turning up. At the same time, the alternate stepping of both feet also gets strength exercise; by rotating the adjusting rod 320 to drive the ball valve 321 to switch between blocking and connecting a pair of liquid storage pipes 310; when the third hole of the flow hole 322 turns to face the liquid storage bladder 313, the two liquid storage pipes 310 are in a connected state, so that when one foot placement box 210 is stepped on and turned down, the pressure liquid rod 330 is smoothly squeezed into the liquid storage pipe 310, and the damping liquid in this liquid storage pipe 310 is transferred to the liquid storage bladder 313, playing a role in temporary storage and conversion of the damping liquid; at the same time, due to the blocking platform 103 blocking the upward turning of the other foot placement box 210, the damping liquid will not leak out from the other liquid storage pipe 310. Then, both feet alternately switch the center of gravity to step on the two foot placement boxes 210 to turn down and enhance the foot strength training. That is, the device adapts the training according to the patient's condition, which is beneficial to rehabilitation.

[0054] It should be noted that the above embodiments are only for explaining the technical concept and characteristics of the present invention, and the purpose is to enable those who are familiar with this technology to understand the content of the present invention and implement it accordingly, and it cannot be used to limit the protection scope of the present invention. Any equivalent changes or modifications made according to the spirit and essence of the present invention should be covered within the protection scope of the present invention.
