[0007] As a further improvement of the technical solution, a plug column is embedded in the rear end side wall of the foot box, and the plug column passes through the upper end side wall of the liquid pressing rod.

[0014] Compared with the prior art, the present invention has the following beneficial effects: 1. The bipedal balance rehabilitation training device, through a dual-mode training mechanism, completes a smooth transition from static balance to dynamic strengthening training: patients can use a horizontal foot box to perform foot drop correction training in the early stage, and in the later stage, they can enhance foot strength by switching to an alternating pedaling mode, thus achieving a step-by-step adaptation of the rehabilitation process.

[0015] 2. The bipedal balance rehabilitation training device can quickly switch the training mode through the deflection block support structure and the ball valve linkage design: the rotating adjustment rod drives the ball valve to control the on and off of the liquid storage tube, and the deflection block is synchronously linked to the limit or release of the foot box, so that the device can flexibly switch between static balance maintenance and dynamic alternating stepping, which is convenient to operate and has high stability.

[0016] 3. The bipedal balance rehabilitation training device achieves the effect of adaptive adjustment of the foot's upward angle through the hinged folding of the foot box and the hydraulic damping system: when stepping on the pedals, the hydraulic rod squeezes the damping fluid and transfers it to the reservoir to form a progressive resistance, which not only avoids joint impact injuries, but also enhances proprioception training through hydraulic feedback.

[0017] 4. The bipedal balance rehabilitation training device ensures precise and controllable mechanical transmission during alternating training through the design of the baffle bar limiter and the one-way connection of the liquid storage tube: when one side of the foot box flips down, the other side remains stable due to the blocking of the baffle bar and the hydraulic blockage, preventing invalid liquid seepage and achieving the continuity and safety of alternating center of gravity transfer of the two feet.

[0018] 5. The bipedal balance rehabilitation training device integrates two functional modules, the trainer and the adjustment group, through a training seat box-type inclined opening structure, to achieve miniaturization of the device and adaptability to training scenarios: the compact layout reduces the space requirements, and the inclined opening facilitates the patient's switching between sitting and standing training, thereby improving the human-computer interaction experience of rehabilitation training.

[0034] See also Figure 1-Figure 11 As shown, the present invention provides a bipedal balance rehabilitation training device, comprising a box-shaped obliquely opened training seat 100, wherein a pair of training devices 200 for bipedal balance standing and an adjustment group 300 for switching the training devices 200 to alternate stepping are arranged inside the training seat 100; Figure 2-Figure 4 As shown, the device has two training modes, one is to train the balance of both feet standing in the trainer 200, and the other is to change the alternating activities of the trainer 200 by adjusting the group 300 so as to increase the training intensity while the feet are maintaining balance and promote rehabilitation.

[0035] Specifically, Figure 5-Figure 7 As shown, the trainer 200 includes a foot box 210 rotatably connected to the inner wall of the front end of the training seat 100 and a foot pedal 220 adapted to be snap-fitted and flipped to the top end of the foot box 210; limit blocks 120 for supporting the foot box 210 are symmetrically arranged on the bottom surface of the rear end of the training seat 100, so that the foot box 210 remains horizontal and supports the standing balance training of both feet; a positioning hole 211 is opened on the side wall of the middle section of the foot box 210 and close to the front end of the training seat 100, and a positioning rod 221 is inserted into the bottom surface of the foot pedal 220 and at a position corresponding to the position of the positioning hole 211. When the foot stands on the foot pedal 220, the foot forms an upturned state; because the positioning hole 211 and the positioning rod 221 are both close to the front end of the foot box 210, the center of gravity of the two feet is located at the rear section of the foot pedal 220, and the feet are kept in an upturned posture. The balance training in this posture is used to overcome the foot drop disease and restore the foot to a normal posture.

[0036] Furthermore, a rotating hole 212 is provided on the front side wall of the foot box 210, and a plug hole 102 is provided on the front side wall of the training seat 100. The foot box 210 and the training seat 100 are rotatably connected by inserting a rotating shaft 140 into the plug hole 102 and the rotating hole 212; two pairs of annular grooves are provided on the rotating shaft 140 and the spacing between each pair of annular grooves is equal to the width of the foot box 210, and the foot box 210 is limited by buckling a retaining spring on the annular groove.

[0037] Furthermore, the front end bottom surface of the foot pedal 220 is fixedly connected to the weight block 222, that is, a metal block with weight, by bolts, and its weight is used to drive the foot pedal 220 to reset and keep it horizontal, so that the two feet can stand steadily next time; by gluing a silicone pad to the bottom surface of the weight block 222, the impact sound of the foot pedal 220 rotating and resetting is eliminated; a stopper 230 is embedded on the rear end top surface of the foot pedal 220, and the stopper 230 is an arc plate with a silicone pad glued on the inside, which is used to support the heel. At the same time, the foot pedal 220 is a plastic part and its top surface is evenly spaced with a number of convex strips to play an anti-slip role; the rear end top surface of the foot pedal 220 is provided with a slot 223 that is plugged into the bottom of the stopper 230, so that the stopper 230 can be disassembled and installed for cleaning or replacement.

[0038] In addition, arc grooves 101 are symmetrically provided on the left and right side walls of the training seat 100, and the arc grooves 101 coincide with the central axis of the insertion hole 102. The rear end side wall of the foot box 210 is provided with a sliding column 213 that is slidably connected with the arc grooves 101, so that the foot box 210 can deflect stably around the rotating shaft 140.

[0039] Specifically, Figure 6 and Figure 10-11 As shown, a stopper 103 is provided inside the front end of the training seat 100 and above the insertion hole 102, which is used to prevent the foot box 210 from turning up. The limit block 120 is a truncated cone structure and has a through slot 121 extending through the front and back sides thereof. A deflection block 130 is rotatably connected inside the through slot 121, and a fixed angle block 122 is provided on the front and back sides of the deflection block 130 for blocking the rotation angle of the deflection block 130. The upper end of the deflection block 130 rotates out of the front of the upper end of the through slot 121 and supports the foot box 210, so that the foot box 210 remains horizontal for bipedal standing training. The bottom inner wall of the through slot 121 is symmetrically provided with three through holes 125, wherein the middle through hole 125 corresponds to the center hole of the deflection block 130 and is connected by a pin. The central angle of the deflection block 130 is smaller than the angle between the two fixed angle blocks 122, so that the deflection block 130 can be adjusted to deflect forward and backward; the other two through holes 125 are connected to the side walls of the two fixed angle blocks 122 by pins, so as to fix and support the deflection block 130.

[0040] Furthermore, a slot 123 is provided on the midline of the bottom surface of the limit block 120, and the rear end bottom surface of the training seat 100 is symmetrically connected to the limit strip 150 by bolts. The limit strip 150 is plugged into the slot 123 to prevent the limit block 120 from sliding forward and backward. The front and rear side walls of the deflection block 130 are provided with a baffle 131 for overlapping the top of the fixed angle block 122, so as to further increase the strength of the deflection block 130 to support the top foot box 210, and the design of the baffle 131 is also convenient for pinching the fingers to pull the deflection block 130 to rotate and adjust the opposite foot box 210 to form a supporting state and a limit-removed state.

[0041] Furthermore, support platforms 124 are symmetrically provided on the front and rear sides of the bottom of the limit block 120 to support the foot box 210 after it is flipped down, so as to control the flipping angle; the front end outer wall of the training seat 100 is fixedly connected with an armrest 110 with a telescopic function, that is, the inner and outer tubes are connected to telescope and adjust the support height, and the height can be positioned by tightening the bolts.

[0042] Specifically, Figure 8 and Fig. 9 The adjustment group 300 shown includes a pair of liquid storage tubes 310 in a bent state, an adjustment rod 320 for adjusting the opening and closing of the near ends of the pair of liquid storage tubes 310, and a liquid pressing rod 330 adapted to be plugged into the rear end of the liquid storage tubes 310; the liquid storage tubes 310 are filled with damping liquid, and the bottom end of the adjustment rod 320 is tightly sleeved with a ball valve 321 for sealing the pipe opening of the liquid storage tubes 310, and the left and right half side walls of the ball valve 321 are symmetrically provided with flow holes 322 for connecting the liquid storage tubes 310. By rotating the adjustment rod 320, the ball valve 321 is driven to switch between blocking and connecting the pair of liquid storage tubes 310. When blocked, the two feet are trained to stand steadily; when connected, the two feet alternately switch the center of gravity to step on the two foot boxes 210 to flip down and enhance foot strength training.

[0043] The front ends of a pair of liquid storage tubes 310 are opposite to each other and are sleeved with a connecting tube 312. A liquid storage capsule 313 is sleeved with a thin tube in the middle of the connecting tube 312. The liquid storage capsule 313 is made of silicone or rubber in a spherical shape. The liquid storage capsule 313 expands to store damping liquid and contracts to squeeze out the damping liquid into the liquid storage tube 310 for temporary storage of damping liquid. The flow hole 322 is a T-shaped three-way hole. The two coaxial holes penetrate the front and rear walls of the ball valve 321. A sealing ring is embedded on the midline of the front and rear walls of the ball valve 321 to separate the two flow holes 322. The first flow hole 322 on the left side Three holes pass through the center of the left side wall of the ball valve 321; when the three holes of the circulation hole 322 are all located at the end of a liquid storage tube 310, the sealing ring is used to seal the thin tube mouth of the liquid storage bag 313, and the two liquid storage tubes 310 are in a blocked state as a whole; when the third hole of the circulation hole 322 turns to face the liquid storage bag 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, and the adjusting rod 320 passes through the top surface of the front end of the training seat 100 and passes through the top of the connecting tube 312 and is tightly plugged into the center of the ball valve 321.

[0044] Furthermore, an upturned arc tube 311 is provided at the rear end of the liquid storage tube 310, and the central axis of the arc tube 311 coincides with the rotation center axis of the footrest box 210, the liquid pressing rod 330 is adapted to be plugged 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 column 214 is embedded in the rear end side wall of the footrest box 210, and the plug column 214 passes through the upper end side wall of the liquid pressing rod 330, so that one of the footrest boxes 210 is stepped on and flipped down, triggering the liquid pressing rod 330 to be smoothly squeezed into the liquid storage tube 310, so that the damping liquid in this liquid storage tube 310 is transferred to the liquid storage bag 313, which plays a role in temporary storage and conversion of the damping liquid; at the same time, the other footrest box 210 is blocked from flipping up by the baffle 103, and the damping liquid will not leak from the other liquid storage tube 310.

[0045] Furthermore, the rearward horizontal bending section of the liquid storage tube 310 is laid along the inner side of the training seat 100 and fixed by a tube clamp, and the setting of the support platform 124 allows the foot box 210 to flip down and stop above the liquid storage tube 310; the top end of the adjustment rod 320 is clamped with a lever 340, and the direction of the lever 340 is consistent with the direction of the flow hole 322, that is, the lever 340 points backward, and both ends of the flow hole 322 are located in one liquid storage tube 310, and the lever 340 points left and right, thereby clearly indicating that the ball valve 321 is in a state of connecting the two liquid storage tubes 310 and the liquid storage bag 313, so that when the foot box 210 moves, the damping fluid is facilitated to flow smoothly to cooperate with its movement.

[0046] The double-foot balance rehabilitation training device of the present invention has two training modes when in use. One is to train the balance of the two feet while standing in the training device 200; the deflection block 130 is rotated to the lower rear end of the foot box 210 for support, so that the foot box 210 is kept in a horizontal state. At this time, when the two feet stand on the foot pedal 220, the heels of the feet step on the foot pedal 220 and turn down to form an upturned state of the feet; the balance training in this posture is used to overcome the foot drop disease and restore the feet to a normal walking posture; Secondly, the training intensity is increased when the two feet maintain balance; by removing the top limit of the opposite foot box 210 by turning the deflection block 130, the two feet standing on the foot box 210 can be lowered and rotated, increasing the angle of the foot upward, and at the same time, the alternating stepping of the two feet can also exercise strength; by rotating the adjustment rod 320, the ball valve 321 is driven to switch between blocking and connecting a pair of liquid storage tubes 310; when the third hole of the flow hole 322 is turned to face the liquid storage bag 313, the two liquid storage tubes 310 are in a connected state, so that one of the foot boxes 21 0 is stepped on and turned down, triggering the liquid pressing rod 330 to be smoothly squeezed into the liquid storage tube 310, so that the damping liquid in the liquid storage tube 310 is transferred to the liquid storage bag 313, which plays a role in temporary storage and conversion of the damping liquid; at the same time, the other foot box 210 is blocked by the stopper 103 from turning up, and the damping liquid will not leak out of the other liquid storage tube 310, so the two feet alternately switch the center of gravity to step on the two foot boxes 210 to turn down to enhance the foot strength training, that is, the device performs adaptive training according to the patient's condition, which is conducive to rehabilitation.
