Abstract
Description
Technical Field

[0002] The human nervous system is particularly important. The nervous system controls various human behaviors and movements. After surgery, nerve patients often experience a decline in their mobility. Therefore, during the later rehabilitation process, it is usually necessary to use a walking aid device in combination for rehabilitation exercises.
[0003] At present, one way of the walking aid device used for rehabilitation exercises mainly relies on the patient to walk independently within a certain space. During this process, support and protection are provided to the patient. However, the ward generally has limited space and is inconvenient to use.

[0042] Secondly, the present invention will be described in detail with reference to the schematic diagrams.

[0043] To make the objectives, technical solutions and advantages of the present invention clearer, the embodiments of the present invention will be further described in detail below with reference to the accompanying drawings.
[0044] The present invention provides a walking aid device for neurological rehabilitation exercises, which replaces the traditional walking aid device used in rehabilitation exercises, and avoids the problems of the device tilting and being unstable due to the patient's center of gravity shifting when the patient alternately pedals left and right during the exercise process, thus causing potential safety hazards and inconvenience in use.
[0045] Figures 1 - 9 Shown is a schematic structural diagram of a walking aid device for neurological rehabilitation exercises of the present invention. Please refer to Figures 1 - 9 for a detailed introduction to this walking aid device for neurological rehabilitation exercises.
[0046] Embodiment 1
[0047] Refer to Figures 1 - 8 , the present invention discloses a walking aid device for neurological rehabilitation exercises, the main body part of which includes a support mechanism 100, a balance mechanism 200 and a leg pressing mechanism 300.
[0048] Refer to Figures 1 - 3 , the support mechanism 100 is used to support the entire body of the patient. The support mechanism 100 includes a support frame 110 and two elastic load-bearing members 120 installed on the left and right sides of the support frame 110 for the patient's left and right feet to support. The support frame 110 is used to support the patient's body, and the elastic load-bearing members 120 are used to weigh the patient's feet;
[0049] Refer to Figures 1 - 5, the balancing mechanism 200 is used to balance the center of gravity of the entire device when the patient alternately presses the left and right elastic load-bearing members 120. The balancing mechanism 200 is installed on the supporting mechanism 100. Among them, when the left elastic load-bearing member 120 is pressed down, it automatically drives the balancing mechanism 200 to start working and balance the center of gravity of the entire device to the right. When the right elastic load-bearing member 120 is pressed down, it automatically drives the balancing mechanism 200 to start working and balance the center of gravity of the entire device to the left. Thus, when the patient's left foot presses down on the left elastic load-bearing member 120, it drives the balancing mechanism 200 to balance the center of gravity of the right side of the device. When the patient's right foot presses down on the right elastic load-bearing member 120, it drives the balancing mechanism 200 to balance the center of gravity of the left side of the device, thereby keeping the center of gravity of the device stable;
[0050] Reference Figures 1 - 8 , the leg pressing mechanism 300 is used to alternately massage the patient's right leg and left leg when the patient performs alternating downward pressing exercises on the left and right legs. The leg pressing mechanism 300 is installed on the left and right sides of the support frame 110. Among them, when the balancing mechanism 200 works to balance the center of gravity of the entire device to the right, it drives the leg pressing mechanism 300 to start working and massage the patient's right leg. When the balancing mechanism 200 works to balance the center of gravity of the entire device to the left, it drives the leg pressing mechanism 300 to start working and massage the patient's left leg. Thus, when the patient's left leg performs a downward pressing exercise, at this time the right leg rises and recovers, and the leg pressing mechanism 300 massages the patient's right leg. When the patient's right leg performs a downward pressing exercise, at this time the left leg rises and recovers, and the leg pressing mechanism 300 massages the patient's left leg, thereby relieving the fatigue generated after the patient's legs have just exerted force.
[0051] In this embodiment, the specific usage process is as follows: When the patient uses the device for rehabilitation exercises, the patient's left and right feet stand on the left and right elastic load-bearing members 120 respectively. When the patient's left leg starts to exert force and push down on the left elastic load-bearing member 120, at this moment the patient's center of gravity drives the device to shift to the left. At this time, the balancing mechanism 200 automatically balances the center of gravity of the device to the right, thereby maintaining the stability of the device. At the same time, the leg pressing mechanism 300 massages the patient's right leg to relieve the fatigue generated after the right leg has just exerted force. Similarly, when the patient's right leg starts to exert force and push down on the left elastic load-bearing member 120, at this moment the patient's center of gravity drives the device to shift to the right. At this time, the balancing mechanism 200 automatically balances the center of gravity of the device to the left, thereby maintaining the stability of the device. At the same time, the leg pressing mechanism 300 massages the patient's left leg to relieve the fatigue generated after the left leg has just exerted force. During this process, the patient alternately exerts force and pushes down with the left and right legs. During the process of the patient's center of gravity alternately shifting, the balancing mechanism 200 balances the shifted center of gravity, thereby simulating the gait of normal walking and improving the rehabilitation exercise effect of the patient.
[0052] Embodiment 2
[0053] Based on Embodiment 1, referring to Figures 1 - 3 , the support frame 110 includes two vertical plates 110a with support feet at the bottom and telescopic brackets 110a-1 at the top, and a cross beam 110b located between the two vertical plates 110a. The vertical plates 110a are used to cooperate with the cross beam 110b to maintain the stability of the entire device. The telescopic bracket 110a-1 is used to support the patient's armpits, thereby reducing the pressure on the patient's legs from their own body weight, and facilitating height adjustment corresponding to the patient's height. The cross beam 110b is used to connect the two vertical plates 110a, thereby improving the stability of the entire device.
[0054] In this embodiment, the side wall of the vertical plate 110a has a first limit sliding groove 110a-2 for slidably connecting the connecting seat 120a;
[0055] Referring to Figures 1 - 4 , the elastic load-bearing member 120 includes a connecting seat 120a with one end extending into the first limit sliding groove 110a-2, a load-bearing plate 120b located on the other side of the connecting seat 120a, and an elastic member 120c with the top connected to the bottom of the connecting seat 120a and the bottom connected to the side wall of the support frame 110. The connecting seat 120a is used to facilitate the connection of the load-bearing plate 120b and the elastic member 120c. The load-bearing plate 120b is used to support the patient's feet. The elastic member 120c is used to provide resistance when the patient's feet are pressed down, thereby providing a supporting force for the load-bearing plate and the legs. The elastic member 120c is a variable stiffness spring group, and the variable stiffness spring group includes three springs coaxially installed and nested in sequence, which is used to achieve the hierarchical compression of the elastic member 120c when the connecting seat 120a is pressed down, and then adjust the supporting force adaptively according to the force condition of the patient's legs.
[0056] In this embodiment, the specific working process is as follows: The left and right feet of the patient are supported by two load-bearing plates 120b respectively. When the patient alternately presses down with the left and right feet, the load-bearing plate 120b drives the connecting seat 120a to move downward alternately. At the same time, the elastic member 120c is hierarchically compressed to provide resistance, thereby supporting the left and right feet of the patient, simulating the state when the patient walks, rehabilitating the patient's mobility, and adaptively adjusting the exercise intensity according to the patient's force condition.
[0057] Embodiment 3
[0058] Based on Embodiment 2, referring to Figures 1 - 4The elastic load-bearing member 120 also includes an overload warning component 120d, which is used to warn when the patient's legs exert too much force or the patient's weight exceeds the bearing capacity of the elastic load-bearing member 120. The overload warning component 120d includes a positioning pin 120d-1 located on one side of the connecting seat 120a and a travel limiting groove 120d-2 located on the side wall of the support frame 110 and corresponding to the positioning pin 120d-1. When the patient's weight is too large or the patient's legs exert too much force, the positioning pin 120d-1 contacts the travel limiting groove 120d-2, thereby generating micro-vibration and transmitting it to the patient's footsteps, thereby completing the warning to the patient.
[0059] Example 4
[0060] Based on Example 3, Figures 1 - 7 The balancing mechanism 200 includes a mounting frame 210 installed between two vertical plates 110a, a center of gravity offset component 220 located on one side of the mounting frame 210, and a center of gravity counterweight component 230 transmission-connected to the center of gravity offset component 220. The mounting frame 210 is used to facilitate the installation of the center of gravity offset component 220 and the center of gravity counterweight component 230. The center of gravity offset component 220 and the center counterweight component are used to cooperate with the center of gravity counterweight component 230 to balance the center of gravity of the device during the process of the patient's left and right feet alternately exerting force on the device, thereby improving the stability of the device.
[0061] In this embodiment, reference Figures 5 - 7 The center of gravity shifting assembly 220 includes a shell 220a installed on the mounting frame 210, a pendulum 220b movably installed on the inner wall of the shell 220a, and a first transmission assembly 220c which is transmission-connected to the elastic load-bearing member 120 at one end and transmission-connected to the pendulum 220b at the other end. The shell 220a is used to facilitate the installation of the pendulum 220b and the damping link 220a-1. The pendulum 220b is used to drive the center of gravity of the device to shift when it swings. The first transmission assembly 220c is used to drive the pendulum 220b to shift to the right when the elastic load-bearing member 120 on the left is pressed down and moved, and to drive the pendulum 220b to shift to the left when the elastic load-bearing member 120 on the right is pressed down and moved.
[0062] In this embodiment, reference Figures 4 - 7 A first sawtooth plate 120a-1 is provided on one side of the connecting seat 120a, and is used to drive the first transmission gear 220c-1 to rotate when the connecting seat 120a moves and drives the first sawtooth plate 120a-1 to move;
[0063] A second limiting sliding groove 110b-1 is provided on the side wall of one of the cross beams 110b, which is used to limit the limiting driving frame 220c-4;
[0064] refer to Figure 7, the first transmission component 220c includes a first transmission gear 220c-1 mounted on the side wall of the vertical plate 110a and meshed with the first serrated plate 120a-1, a first pulley 220c-2 with one end connected to the side wall of the first transmission gear 220c-1 through a rotating shaft, a first threaded rod 220c-3 mounted on the side wall of the cross beam 110b, a limit driving frame 220c-4 threadedly sleeved on the first threaded rod 220c-3 and with its side wall extending into the second limit chute 110b-1, second pulleys 220c-5 located at both ends of the first threaded rod 220c-3 and respectively connected to the corresponding first pulley 220c-2 through a belt, and a rib 220c-6 located at the bottom of the pendulum 220b and corresponding to the limit driving frame 220c-4. The first transmission gear 220c-1 is used to drive the first pulley 220c-2 to rotate when rotating, the first pulley 220c-2 is used to drive the first threaded rod 220c-3 to rotate when rotating, the first threaded rod 220c-3 is used to drive the limit driving member to move under the limiting action of the second limit chute 110b-1 when rotating, the limit driving member is used to drive the rib 220c-6 to swing when moving, and the rib 220c-6 is used to drive the pendulum 220b to swing when swinging;
[0065] Reference Figure 6 , two damping link rods 220a-1 are arranged in the housing 220a, which are used to consume the energy of the vibration generated when the pendulum 220b swings. The damping link rod 220a-1 is of a double-layer sleeve structure. The outer tube is filled with silicone oil and its end is hinged to the inner wall of the housing 220a. The end of the outer tube has a pressure relief hole, which is used to relieve the high-pressure air in the outer tube when the inner rod moves into the outer tube, so as to avoid being stuck due to high-pressure air. The end of the inner rod is provided with a piston located in the outer tube and the other end is hinged to the side wall of the pendulum 220b.
[0066] In this embodiment, a third limit chute 210a is opened on the side wall of the mounting frame 210, which is used to limit the counterweight slider 230d;
[0067] Reference Figure 5 , the center of gravity counterweight assembly 230 includes a differential 230a mounted on the side wall of the mounting frame 210 and with one end connected to the side wall of the pendulum 220b through a rotating shaft, a first bevel gear set 230b with one end connected to the other end of the differential 230a, a second threaded rod 230c located at the other end of the first bevel gear set 230b, and a counterweight slider 230d threadedly sleeved on the second threaded rod 230c and with its side wall extending into the third limit chute 210a. The differential 230a is used to drive the first bevel gear set 230b to rotate at an accelerated speed when the pendulum 220b rotates, the first bevel gear set 230b is used to drive the second threaded rod 230c to rotate when rotating, and the second threaded rod 230c is used to drive the counterweight slider 230d to move under the limiting action of the third limit chute 210a when rotating.
[0068] In this embodiment, a connecting member (not shown in the figure) is connected to the rotating shaft connecting the two first transmission gears 220c-1 and the two first pulleys 220c-2. The connecting member includes a ratchet connecting seat 120a having a ratchet groove on the side wall and a ratchet located in the ratchet groove and having a plurality of elastic pawls on the circumferential side wall, which is used to press down the elastic load-bearing member 120 on the left. When the first transmission gear 220c-1 on the left rotates, it drives the first threaded rod 220c-3 to rotate, thereby indirectly generating a force to drive the elastic load-bearing member 120 on the right to press down, thereby making it impossible to alternately press down and lift the left and right feet.
[0069] In this embodiment, the specific working process is as follows: when the patient's left foot exerts force to push down, the first serrated plate 120a-1 on the left moves to drive the first transmission gear 220c-1 on the left to rotate, thereby driving the first threaded rod 220c-3 to rotate after the first pulley 220c-2 and the second pulley 220c-5 on the left rotate. When the first threaded rod 220c-3 rotates, it drives the limit drive frame 220c-4 to move rightward. When it collides with the convex strip 220c-6, the pendulum 220b obtains an initial velocity to the right, thereby driving the pendulum 220b to swing to the right. When the pendulum 220b swings to the right, it drives the differential 230a to rotate, thereby driving the first bevel gear set 230b to rotate. When the first bevel gear set 230b rotates, the second threaded rod 230c rotates. When the second threaded rod 230c rotates, it drives the two counterweight sliders 230d to move to the right synchronously. Therefore, under the action of the pendulum 220b swinging to the right and the two counterweight sliders 230d moving to the right, the center of gravity of the device is balanced to the right, thereby maintaining the stability of the device. At the same time, when the patient lifts his left foot and pushes with his right foot, the balancing mechanism 200 balances the center of gravity of the device to the left.

The connecting plate 310 is used to facilitate the installation of the massage piece 320 and the second transmission assembly 330. The massage piece 320 is used to massage the patient's legs during operation, thereby relieving fatigue after exerting force. The second transmission assembly 330 is used to drive the massage piece 320 on the left to massage the patient's left leg when the counterweight slider 230d slides to a certain position to the left, and to drive the massage piece 320 on the left to massage the patient's right leg when the counterweight slider 230d slides to a certain position to the right.
[0072] In this embodiment, referring to Figures 8 - 9 , the side wall of the connecting plate 310 is provided with a reciprocating lead screw 310a and a limiting slide bar 310b. The reciprocating lead screw 310a is used to drive the massage member 320 to move up and down reciprocally when rotating, and the limiting slide bar 310b is used to limit the massage member 320, so as to prevent it from rotating synchronously when the reciprocating lead screw 310a rotates;
[0073] Referring to Figure 5 , the bottom of the counterweight slider 230d is provided with a second serrated plate 230d-1, which is used to drive the second transmission gear 330a to rotate when moving;
[0074] Referring to Figures 8 - 9 , the second transmission assembly 330 includes a second transmission gear 330a installed at the bottom of the mounting frame 210 and meshed with the second serrated plate 230d-1, a second bevel gear set 330b with one end connected to the side wall of the second transmission gear 330a, a third pulley 330c with the top connected to the other end of the second bevel gear set 330b through a rotating shaft, and a fourth pulley 330d with one end connected to the reciprocating lead screw 310a through a rotating shaft and connected to the third pulley 330c through a belt. The second transmission gear 330a is used to drive the second bevel gear set 330b to rotate when rotating, the second bevel gear set 330b is used to drive the third pulley 330c to rotate when rotating, the third pulley 330c is used to drive the fourth pulley 330d to rotate when rotating, and the fourth pulley 330d is used to drive the reciprocating lead screw 310a to rotate when rotating;
[0075] Referring to Figures 8 - 9 , the massage member 320 includes a connecting frame 320a with one end threadedly sleeved on the reciprocating lead screw 310a and the other end slidably sleeved on the limiting slide bar 310b, and a plurality of elastic pressing belts 320b connected to the inner side of the connecting frame 320a. The connecting frame 320a is used to facilitate the installation of the elastic pressing belts 320b, and the elastic pressing belts 320b are used to elastically support the patient's legs.
[0076] In this embodiment, the specific working process is as follows: when the patient's left leg kicks downward, at this time the right leg rises and recovers, and the counterweight slider 230d of the balance mechanism 200 moves to the right. At this time, the second serrated plate 230d-1 moves to drive the second transmission gear 330a on the right to rotate, and then drives the second bevel gear set 330b on the right to rotate. When the second bevel gear set 330b on the right rotates, it drives the third pulley 330c on the right to rotate, thereby driving the fourth pulley 330d on the right to rotate and then driving the reciprocating lead screw 310a on the right to rotate. When the reciprocating lead screw 310a on the right rotates, it drives the connecting frame 320a on the right to move up and down reciprocally, so as to massage the patient's right leg through elastic pressing, thereby relieving the fatigue generated after the right leg has just exerted force. Similarly, when the patient's right leg kicks downward and the left leg rises and recovers, the left leg that has just exerted force is massaged.
