Description

Technical Field

[0001] The invention relates to the technical field of rehabilitation equipment, and in particular to an ankle rehabilitation training device for plateau soldiers. Background Art

[0002] The plateau has a complex terrain, with many mountains and rugged terrain. Soldiers have heavy daily training tasks, including long-distance marches with loads, high-intensity physical training, and combat exercises in complex terrain. These high-intensity activities put great pressure on soldiers' ankles and make them very susceptible to injury. Moreover, the hypoxic environment of the plateau can lead to poor blood circulation and decreased muscle endurance, further increasing the risk of ankle injuries. Once an ankle is injured, if it does not receive timely and effective rehabilitation treatment, it will not only affect the soldier's daily training and execution of tasks, but may even have long-term adverse effects on his military career.

[0003] The human body's metabolism is slow in the plateau environment, the recovery period after ankle injury is significantly prolonged, and edema is more serious and difficult to subside. Most traditional ankle rehabilitation training devices are designed based on the usage needs of people in plain areas, without fully considering the impact of the plateau environment. For example, in terms of promoting blood circulation, traditional devices usually only focus on driving local blood flow through simple joint movements, and it is difficult to effectively deal with the blood circulation disorders caused by hypoxia in plateau soldiers. Like general ankle flexion and extension trainers, although they can assist ankle movements, they lack deep massage and squeezing functions for calf muscles and soles of feet, which are prone to edema, and cannot strongly promote blood return and reduce edema. This makes the rehabilitation effect of plateau soldiers greatly reduced when using traditional devices, making it difficult to quickly restore ankle function and unable to meet the urgent needs of plateau military training and combat, highlighting the necessity of developing new ankle rehabilitation training devices suitable for plateau soldiers.

[0035] In order to make the purpose, technical scheme and advantages of the embodiment of the present invention clearer, the technical scheme of the embodiment of the present invention will be clearly and completely described in conjunction with the drawings of the embodiment of the present invention. Obviously, the described embodiment is a part of the embodiment of the present invention, not all of the embodiments. Based on the described embodiment of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work belong to the scope of protection of the present invention. The schematic implementation mode of the present invention and its description are only used to explain the present invention and are not intended to limit the present invention. It should be noted that the present invention is already in the actual research and development stage.

[0036] Unless otherwise defined, the technical terms or scientific terms used in the present invention shall have the usual meanings understood by persons with ordinary skills in the field to which the present invention belongs. The words "first", "second" and similar words used in the present invention do not indicate any order, quantity or importance, but are only used to distinguish different components. The words "include" or "comprise" and similar words mean that the elements or objects appearing before the word include the elements or objects listed after the word and their equivalents, without excluding other elements or objects.

[0037] In plateau environments, human metabolism becomes slow. After soldiers injure their ankles, they face the dilemma of greatly extended recovery periods, severe edema, and difficulty in relieving it. Traditional ankle rehabilitation training devices are mostly aimed at people in plain areas, without taking into account the particularity of the plateau. In terms of promoting blood circulation, simple joint movements are often used to drive blood flow, and there is no way to deal with blood circulation disorders caused by hypoxia in plateau soldiers. Although common ankle flexion and extension trainers assist the ankle in moving, they can neither deeply massage nor effectively squeeze the calves and soles of the feet, which are prone to edema, and it is difficult to promote blood return and reduce edema. As a result, the rehabilitation effect of plateau soldiers using traditional devices is poor, and the ankle function recovers slowly.

[0038] Embodiment 1:

[0039] like Figure 1 , Figure 2 As shown, the present embodiment provides an ankle rehabilitation training device for plateau soldiers, comprising a support seat 30, a foot support plate 10 and a cylinder 20. The foot support plate 10 and the cylinder 20 are both arranged inside the support seat 30. A connecting rod 15 is provided on the inner wall of the support seat 30. The foot support plate 10 is hinged to the connecting rod 15. A connecting plate 13 is provided on the foot support plate 10. One end of the connecting plate 13 is connected to the foot support plate 10, and the other end of the connecting plate 13 is hinged to the outer end of the cylinder shaft 21 of the cylinder 20. When the cylinder shaft 21 moves, the foot support plate 10 can rotate around the axis of the connecting rod 15; a massage mechanism is provided on the foot support plate 10. When the cylinder shaft 21 moves, it can simultaneously drive the massage mechanism to massage the sole of the foot; the ankle rehabilitation training device for plateau soldiers in the present embodiment also includes a squeezing mechanism. In the vertical direction, the squeezing mechanism is arranged above the massage mechanism. When the cylinder 20 moves, it can simultaneously drive the squeezing mechanism to squeeze the calf.

[0040] The support base 30 serves as the foundation of the entire device, providing stable support for each component. The connecting rod 15 on its inner wall ensures that the footrest 10 can be flexibly hinged to achieve a rotation function similar to that of the ankle. The footrest 10 carries the soldier's foot, and the connecting plate 13 thereon is hinged to the outer end of the cylinder shaft 21 of the cylinder 20, so that when the cylinder shaft 21 is extended or retracted, the footrest 10 is accurately driven to rotate around the connecting rod 15, simulating ankle flexion and extension, and helping soldiers restore joint mobility. When working, start the cylinder 20, and as the cylinder shaft 21 moves, the footrest 10 rotates according to the set trajectory. At the same time, the massage mechanism on the footrest 10 is triggered to massage the sole of the foot and stimulate blood circulation; the squeezing mechanism squeezes the calf in the vertical direction to accelerate blood return, effectively combat edema, and fully assist plateau soldiers in rapid recovery.

[0041] like Figure 2 , Figure 3 , Figure 6 , Figure 7 and Figure 8 The massage mechanism includes a rotating rod 41, a first gear 40 and a pulley 42. The two ends of the rotating rod 41 are respectively connected to the inner wall of the support seat 30. The first gear 40 and the pulley 42 are fixedly sleeved on the outer edge of the rotating rod 41; the outer edge of the cylinder shaft 21 is provided with a first gear segment 22 matching the first gear 40; the foot support plate 10 is provided with a cavity 16 inside, and a piston plate 19 and a spring 18 are provided in the cavity 16. The piston plate 19 matches the cavity 16, and the piston plate 19 divides the cavity 16 into a first chamber and a second chamber; one end of the spring 18 is connected to the inner wall of the cavity 16, and the other end of the spring 18 is connected to the piston plate 19; one end of the piston plate 19 is connected to the spring Spring 18, a transmission belt 43 connecting the piston plate 19 and the pulley 42 is provided between the other end of the piston plate 19 and the pulley 42, one end of the transmission belt 43 is fixedly connected to the piston plate 19, and the other end of the transmission belt 43 is fixedly connected to the pulley 42; an opening 17 connecting to the cavity 16 is provided on the side of the foot support plate 10 contacting the sole, and an airbag 12 closing the opening 17 is provided above the opening 17; when the cylinder shaft 21 moves, it can drive the piston plate 19 to move in the cavity 16 through the first gear section 22, the first gear 40 and the pulley 42, and when the volume of the first chamber or the second chamber is compressed, the gas can enter the airbag 12 at the corresponding position and make the airbag 12 bulge.

[0042] The rotating rod 41 provides support for subsequent transmission components. The first gear 40 and the pulley 42 are tightly sleeved on the outer edge of the rotating rod 41 to ensure synchronous and stable rotation. When the cylinder shaft 21 moves, the first gear section 22 on its outer edge precisely meshes with the first gear 40, and power is transmitted thereby. The pulley 42 is linked to the piston plate 19 through a metal transmission belt 43. The piston plate 19 divides the cavity 16 of the foot support plate 10 into a first chamber and a second chamber. The spring 18 elastically connects the inner wall of the cavity 16 and the piston plate 19, assisting the piston plate 19 in resetting and buffering the impact of movement. When the cylinder shaft 21 drives the first gear 40 to rotate, the piston plate 19 is driven to move back and forth along a path parallel to the axis of the foot support plate 10 through the pulley 42 and the transmission belt 43, and the compression chamber causes the gas to flow into the corresponding airbag 12 through the opening 17. The airbag 12 swells to perform multi-point massage on the sole of the foot, deeply stimulates the acupuncture points and muscle tissues on the sole of the foot, strongly promotes blood circulation, and accelerates the recovery process of the ankle.

[0043] When a soldier uses the device, the elastic band 32 can automatically adjust the degree of restraint according to the thickness of the calf. On the one hand, it can firmly fix the calf on the leg support to ensure that the calf will not shift when the squeezing mechanism is working, thereby ensuring the precise implementation of the roller's calf massage and squeezing action; on the other hand, the appropriate tightness can not only avoid discomfort to the soldier due to excessive tightness, but also maintain a stable contact pressure throughout the training process.

[0044] In this embodiment, there are multiple openings 17 and multiple air bags 12 , and the multiple air bags 12 and openings 17 are evenly arranged on the foot support plate 10 .

[0045] It ensures that no matter what angle the soldier's feet are placed at, all parts of the soles of the feet can receive timely and appropriate squeezing and massage from the airbags 12, eliminating massage blind spots, allowing the effect of promoting blood circulation to cover the entire sole of the foot, and maximizing the stimulation of the sole muscles and nerves.

[0046] In this embodiment, the movement path of the piston plate 19 in the cavity 16 is parallel to the axial direction of the foot support plate 10 .

[0047] When the piston plate 19 compresses the chamber, the gas is evenly stressed and flows stably, and can be accurately and orderly filled into the airbag 12 above the corresponding opening 17, avoiding problems such as uneven swelling of the airbag 12 and reduced massage effect due to gas turbulence, so that the rhythm of the foot massage is consistent and the force is balanced, which effectively promotes the improvement of blood circulation.

[0048] like Figure 2 , Figure 4 and Figure 5In this embodiment, the squeezing mechanism includes a leg support plate 31 and a rod 33, the two ends of the rod 33 are respectively connected to the inner wall of the support seat 30, and the leg support plate 31 is connected to the rod 33; a rotating shaft 522 and a slot 311 are provided on the leg support plate 31, the two ends of the rotating shaft 522 are respectively rotatably connected to the inner wall of the leg support plate 31 and extend into the slot 311, the rotating shaft 522 is located between the inner walls of the leg support plate 31. The fixed sleeve is provided with a roller 52, and the part of the rotating shaft 522 extending into the slot 311 is provided with a second gear 523; a movable rod 50 matching the slot 311 is provided in the slot 311, and a second gear segment 51 is provided on the movable rod 50, and the second gear segment 51 is matched with the first gear 40 and the second gear 523 respectively; when the cylinder shaft 21 moves, the roller 52 can be rotated through the first gear segment 22, the first gear 40, the second gear segment 51 and the second gear 523 to squeeze the calf.

[0049] A rotating shaft 522 is arranged inside the leg support plate 31, and both ends of the rotating shaft 522 smoothly rotate to connect the inner wall of the leg support plate 31 and partially extend into the slot 311. The roller 52 is tightly sleeved on the part of the rotating shaft 522 between the inner walls of the leg support plate 31, and the surface is covered with protrusions 521 to enhance the massage touch of the calf. The slot 311 is equipped with a movable rod 50 with a second gear segment 51. When the cylinder shaft 21 moves, the first gear segment 22 on its outer edge drives the first gear 40, the second gear segment 51, and the second gear 523 to mesh and rotate in turn, thereby driving the rotating shaft 522 to rotate, and the roller 52 rotates accordingly, squeezing and massaging the calf from multiple directions, accelerating the blood return in the calf area, and coordinating with the foot massage mechanism to speed up the ankle rehabilitation process of plateau soldiers in all directions.

[0050] Working process:

[0051] When plateau soldiers start to use the ankle rehabilitation training device, first, the cylinder 20 is started, and the cylinder shaft 21 stretches or contracts according to the preset program, so that the foot support plate 10 rotates around the connecting rod 15, allowing the ankle to flex and extend. In addition, the first gear section 22 on the outer edge of the cylinder shaft 21 rotates accordingly, driving the first gear 40 meshing with it to rotate, thereby causing the rotating rod 41 and the pulley 42 thereon to rotate synchronously. The pulley 42 pulls the piston plate 19 through the metal transmission belt 43 to move in the cavity 16 of the foot support plate 10 along a path parallel to the axis of the foot support plate 10, and the compression chamber causes the gas to flow into the corresponding airbag 12 through the evenly distributed openings 17, and the airbag 12 swells to massage the sole of the foot. At the same time, the movement of the cylinder shaft 21 also drives a series of gears of the first extrusion unit to mesh and operate, and the mirror-image second extrusion unit based on the midpoint of the rotating rod 41 cooperates and drives the roller 52 (or a multi-roller 52 structure) on the rotating shaft 522 to rotate. The protrusions 521 on its surface accurately touch and knead the calf, and flexibly adjust the extrusion force from different angles on both sides according to the muscle condition, thereby promoting blood circulation in all directions, relieving edema, and realizing ankle rehabilitation training.

[0052] Embodiment 2:

[0053] As an optimization solution of embodiment 1, in this embodiment, the material of the transmission belt 43 is metal material. The metal transmission belt 43 has high strength and high toughness characteristics, and can withstand huge tension and friction during the frequent rotation of the pulley 42 driven by the cylinder shaft 21, avoiding problems such as breakage and slipping.

[0054] In this embodiment, a plurality of protrusions 521 are evenly arranged on the roller 52. When the roller 52 is driven by the cylinder shaft 21 to rotate, these protrusions 521 act like dense massage contacts, and continuously and rhythmically deeply press and knead the calf muscles as the roller 52 rolls. The design of the protrusions 521 can accurately reach the deep layer of the muscles, effectively loosen the tense and stiff muscle tissues due to long-term training, promote local blood circulation, accelerate the discharge of metabolic waste, and cooperate with the entire device to more efficiently relieve the calf edema.

[0055] Embodiment 3:

[0056] Based on the above embodiments, this embodiment adopts a mirror-image dual extrusion unit layout. The cylinder 20, the cylinder shaft 21, the first gear segment 22, the first gear 40, the movable rod 50, the second gear segment 51, and the second gear 523 are combined into a first extrusion unit. Taking the midpoint of the rotating rod 41 as a reference, the ankle rehabilitation training device for plateau soldiers is also provided with a second extrusion unit that is mirror-imaged to the first extrusion unit.

[0057] Taking the midpoint of the rotating rod 41 as the reference, the first extrusion unit composed of the cylinder 20, the cylinder shaft 21, the first gear segment 22, the first gear 40, the movable rod 50, the second gear segment 51, and the second gear 523 cooperates with the second extrusion unit which is mirror-symmetrical to it to exert force on the calf from different angles on both sides simultaneously. When the device is running, the rollers 52 of the two extrusion units rotate at the same time and work together, which not only expands the massage coverage, but also can flexibly adjust the extrusion intensity according to the muscle thickness and tension of different parts of the calf, comprehensively strengthen the blood circulation promotion effect, and provide stronger power for the ankle rehabilitation of plateau soldiers.

[0058] In this embodiment, a plurality of rollers 52 are fixedly sleeved on the rotating shaft 522. The plurality of rollers 52 are closely arranged along the axial direction of the rotating shaft 522. When the rotating shaft 522 is driven by the cylinder shaft 21 to rotate, the rollers 52 roll synchronously, and a larger area of ​​the calf is squeezed and massaged at one time. Compared with a single roller 52, the multi-roller 52 structure greatly increases the contact area with the calf, reduces the blind spot of the massage, and makes the blood return acceleration effect more significant, so that all parts of the calf can be fully mechanically stimulated, which is more conducive to assisting plateau soldiers to accelerate the recovery of body functions.

[0059] The airbag is made of silicone rubber, a material with excellent biocompatibility. It is non-toxic, odorless, and non-allergic to the human body. Its softness and elasticity can provide a comfortable massage touch, just like a gentle massage on the soles of the feet. Silicone rubber also has good high and low temperature resistance. It can maintain stable physical properties under different plateau ambient temperatures, ensuring the normal use of the airbag, and will not harden or soften due to temperature changes, affecting the massage effect.

[0060] The above embodiments are only used to illustrate the technical solutions of the present disclosure, rather than to limit them; although the present disclosure has been described in detail with reference to the aforementioned embodiments, those of ordinary skill in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or replace some of the technical features therein by equivalents; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the spirit and scope of the technical solutions of the various embodiments of the present disclosure.
