Description

Technical Field

[0001] The present invention relates to the technical field of medical auxiliary devices, and in particular to a protective brace for a knee joint. Background Art

[0002] The knee joint is a flexion joint in the middle of the human lower limb. The knee joint is mainly composed of three bones: the femur, tibia, and patella, which are connected to each other by ligaments and tendons. The inside of the joint is covered with a layer of smooth cartilage, which can reduce friction, absorb shock, and protect the joint. In addition, the knee joint also contains two menisci - the medial meniscus and the lateral meniscus, which function to cushion and stabilize the joint. It can be seen that the knee joint is vital to the human body.

[0003] The protective brace for the knee joint in the prior art can wrap the knee joint, pull the leg muscles, and thus support and protect the knee joint. However, since the knee joints of users are in different shapes when exercising, standing, and sitting for a long time, the stress conditions are also different, and the protective brace for the knee joint in the prior art cannot provide different support for the knee joints in different postures, resulting in a low protection effect.

[0004] In summary, how to solve the problem that the existing protective brace for the knee joint cannot provide different supports for the knee joint in different postures, resulting in low protection effect, has become a difficult problem that needs to be solved in the current field. Therefore, it is necessary to propose a targeted protective brace for the knee joint. Summary of the invention

[0005] In order to solve the above problems, the present invention provides a protective brace for the knee joint. Through the design of the protective component, it can effectively wrap and support the user's knee joint, thereby protecting the user's knee joint. In the process, it can also adapt to the changes of the user's knee joint and provide dynamic support and protection for the user.

[0006] In order to achieve the above-mentioned purpose, the technical solution of the present invention is as follows: a protective brace for a knee joint, comprising a flexible knee pad collar, wherein protective components for protecting the knee joint are symmetrically arranged on both sides of the knee pad collar, and the knee pad collar is also provided with a care component for heating and massaging and a data monitoring system for monitoring the movement of the knee.

[0007] The protection component includes a central rod and a controller. A plurality of first connecting rods and second connecting rods are hinged on the central rod in an alternating manner. The first connecting rods and the second connecting rods are both U-shaped and symmetrically arranged. Sliding rods are symmetrically arranged on both sides of the central rod. The first connecting rod and the second connecting rod are both hinged to the sliding rods adjacent thereto. Slide blocks are hinged at both ends of the sliding rods. The slide blocks are slidably matched with support plates. The side walls of the support plates on one side of the sliding rod are fixedly connected to the inner wall of the knee pad collar, and the side walls of the support plates on the other side of the sliding rod are rotatably matched with the inner wall of the knee pad collar. The side walls of the support plates are fixedly connected to electromagnets. The controller is used to control the magnitude and direction of the electromagnetic force of the electromagnets, thereby adjusting the magnitude and direction of the supporting force of the support plates.

[0008] Fixed rods are symmetrically arranged on both sides of the central rod. The ends of the first connecting rod and the second connecting rod away from the sliding rod are hinged to the adjacent fixed rods; and the two ends of the fixed rods are fixedly connected to the adjacent support plates respectively.

[0009] The technical principles of the above scheme are as follows:

[0010] The knee sleeve is set on the knee to fit the user's skin, and the position of the support plate is adjusted so that the support plate is aligned with the front and back sides of the user's knee. When the user's knee is straightened, the controller will control the electromagnets on both sides of the user's knee to attract each other, the electromagnet on the front side of the knee provides the user with the traction required for straightening, and the electromagnet on the back side of the knee provides the user with the support required for straightening, thereby assisting the user's knee to remain straight. When the user's knee is bent, the controller will control the electromagnets on both sides of the user's knee to repel each other, thereby simultaneously providing the knee with the traction required for bending, assisting the user's knee to bend. When the user moves, the controller will repeatedly adjust the direction of the current, thereby adjusting the magnetism of the electromagnet, and adjust the current size according to the speed of the user's leg movement, thereby adjusting the size of the attraction of the electromagnet. The faster the movement, the greater the attraction, and the slower the movement, the smaller the attraction, thereby adapting to movements of different rhythms. When the user's thigh and calf remain vertical for more than 5s, it is judged that the user remains standing; at this time, the electromagnets on both sides of the knee attract each other to provide support for the user.

[0011] The above scheme has the following beneficial effects:

[0012] 1. The present invention combines the design of a support plate with an electromagnet, and respectively sets two groups of support plates on the front and rear sides of the user's knees. When the user needs to keep the knees straight, the electromagnets are used to attract each other to make the support plates move to a vertical state and be fixed, thereby generating a force to assist the user in straightening the knees, and generating a reasonable supporting force after the user's knees are straightened, thereby providing the user with a standing assistance function; when the user is exercising, the controller continuously changes the direction of the current, so that the electromagnet continuously generates a repulsive force and an attractive force, and then continuously provides traction and supporting force to the user during the user's exercise process, thereby assisting the user in exercising; and in this process, by detecting the user's movement amplitude and movement speed, the current size is adaptively adjusted, and then the size of the repulsive force and the attractive force is controlled, so as to provide different sizes, angles and directions of auxiliary forces for different exercise situations, thereby providing adaptive support and protection for the knee joints in different postures.

[0013] 2. The present invention uses electromagnetic force as the driving force and utilizes a unique mechanical structure design so that the support plate can be rotated to different angles to provide adaptive support and protection for the user. At the same time, no additional driving device is added, which greatly reduces the overall weight of the device and does not cause weight burden on the user's knees.

[0014] 3. Compared with the prior art, the present invention not only wraps the user's knees with a flexible knee pad ring to provide support and protection for the user, but also combines a rigid support plate to provide rigid support for the user's knees, thereby increasing the support strength without affecting the user's comfort and providing a motion-assisting function.

[0015] Furthermore, the nursing component includes a plurality of channels transversely opened in the knee pad ring; a plurality of magnetic balls are rollingly fitted in the channels, and a plurality of magnetic blocks are fixedly connected in the knee pad ring; the magnetic blocks are evenly distributed on the outside of the channels, and the controller is used to adjust the adsorption force of the magnetic blocks on the balls.

[0016] Beneficial effects: When the user is exercising, a number of balls will roll in channels at different heights, thereby producing a fluid massage on the user's skin; and due to the magnetic field generated by the electromagnets on both sides of the user's knees, the magnetic balls will roll more strongly and regularly; at the same time, the controller will also regularly adjust each magnetic block to attract the balls; thereby, a number of more balls will evenly massage the user's skin, thereby improving the massage effect; and during the user's exercise, the balls will constantly rub against the user's skin, and both the balls and the user's skin will generate a certain amount of heat, thereby heating the user's legs and enhancing blood flow in the user's legs; the user's legs are heated and cared for while being massaged, and the two work together to further improve the user's comfort.

[0017] Furthermore, the channels are all wavy in shape.

[0018] Beneficial effects: The wavy design can increase the length of the channel, so that the balls have more rolling space, thereby achieving better massage effects, increasing the friction distance, generating more heat, and producing better massage effects and heating care effects.

[0019] Furthermore, a plurality of elastic protrusions are fixedly connected to the inner bottom wall of the channel.

[0020] Beneficial effects: During the rolling process of the ball, the ball will continuously collide with the elastic bumps, thereby enhancing the rolling effect of the ball. At the same time, the ball will continuously bounce during the rolling process, expanding the range of massage, increasing the frequency of friction, and further producing better massage effects and heating care effects.

[0021] Furthermore, a plurality of resin support strips are vertically fixedly connected inside the knee pad collar.

[0022] Beneficial effects: The resin support strip can further provide support for the user's knees, and the resin support strip has good elasticity, and can adapt to the movement of the user's legs while supporting the user's knees.

[0023] Furthermore, support rods are symmetrically arranged on both sides of the center rod, and both ends of the support rods are fixedly connected to the support plates adjacent thereto.

[0024] Beneficial effect: The support rod can provide good support effect for the support plate, thereby better providing support and protection for the user's knees.

[0025] Furthermore, the knee pad ring is made of cotton material.

[0026] Beneficial effects: Cotton cloth has good comfort, breathability and perspiration-wicking properties, can keep the knee joint dry and comfortable, reduce discomfort during exercise, and at the same time can keep warm well, improving the effect of heating care.

[0027] Furthermore, both ends of the knee pad ring are fixedly connected with elastic rings.

[0028] Beneficial effect: The design of the elastic ring enables the knee sleeve to adapt to users of different body shapes, quickly fit the user's legs, and provide users with improved support and protection.

[0029] Furthermore, a knee pad is fixedly connected to the outer side wall of the knee pad ring near the knee, and a plurality of heating wires are fixedly connected inside the knee pad. The controller is used to control the heating temperature of the heating wires.

[0030] Beneficial effect: The design of the heating wire can further provide heating care for the user's knee area and improve the effect of heating care.

[0031] Furthermore, the data monitoring system includes a temperature monitoring module, a motion monitoring module and a limb monitoring module.

[0032] The temperature monitoring module is used to monitor the ambient temperature and the temperature of the user's knees in real time, adjust the temperature of the user's knees in real time according to the temperature of the user's knees, and provide travel suggestions to the user based on the ambient temperature.

[0033] The exercise monitoring module is used to monitor the user's exercise status, exercise volume and exercise duration, and provide exercise adjustment suggestions based on the user's exercise status, exercise volume and exercise duration, combined with changes in the temperature value of the user's knee.

[0034] The limb monitoring module is used to detect the user's leg size, the current leg shape and the bending angle of each leg bending, and then judge the movement state of the user's legs according to the current leg shape, and judge the user's movement amplitude according to the bending angle of each leg bending, and then adjust the size and angle of the support board and provide posture adjustment suggestions.

[0035] Beneficial effects: During exercise, the temperature monitoring module can monitor the ambient temperature and the temperature of the user's knees in real time; according to the temperature of the user's knees, the module can adjust the temperature of the knees in real time to maintain the comfort of the knees. At the same time, according to the ambient temperature, the temperature monitoring module can provide users with travel suggestions, such as whether it is suitable to go out, suitable clothing to wear when going out, and the duration of outdoor exercise. The exercise monitoring module can monitor the user's exercise status, exercise volume and exercise duration. By analyzing these data, the module can evaluate the user's exercise habits and intensity, so as to provide users with personalized exercise suggestions. The limb monitoring module can detect the size of the user's legs, the current shape of the legs, and the degree of bending of the legs each time. The posture adjustment suggestions help improve the user's sitting, standing and walking postures, thereby reducing knee pressure and discomfort caused by poor posture.

DETAILED DESCRIPTION

[0043] The following is further described in detail through specific implementation methods:

[0044] Embodiment 1:

[0045] like Figure 1-5 As shown, a protective brace for the knee joint includes a protective brace for the knee joint, including a flexible knee pad ring 1, and protective components for protecting the knee joint are symmetrically arranged on both sides of the knee pad ring 1. The knee pad ring 1 is also provided with a care component for heating and massaging and a data monitoring system for monitoring the movement of the knee.

[0046] like Figure 3-4 As shown, the protection component includes a central rod 4 and a controller, and a plurality of first connecting rods 5 and second connecting rods 6 are staggered and hinged on the central rod 4, and the first connecting rods 5 and the second connecting rods 6 are both U-shaped and symmetrically arranged; sliding rods 8 are symmetrically arranged on both sides of the central rod 4, and the first connecting rods 5 and the second connecting rods 6 are both hinged to the sliding rods 8 adjacent thereto, and sliders 9 are hinged at both ends of the sliding rods 8, and the sliders 9 are slidably matched with the support plate 2, and the side walls of the lower support plate 2 are fixedly bonded to the inner wall of the knee pad ring 1, and the side walls of the upper support plate 2 are rotatably matched with the inner wall of the knee pad ring 1; the side walls of the support plate 2 are bolted and fixedly connected with the electromagnet 3; the controller is used to control the magnitude and direction of the electromagnetic force of the electromagnet 3, and thereby adjust the magnitude and direction of the supporting force of the support plate 2.

[0047] Fixed rods 7 are symmetrically arranged on both sides of the center rod 4. The ends of the first connecting rod 5 and the second connecting rod 6 away from the sliding rod 8 are hinged to the adjacent fixed rod 7; the two ends of the fixed rod 7 are respectively fixedly connected to the adjacent support plates 2 by bolts.

[0048] Support rods 10 are symmetrically arranged on both sides of the center rod 4, and both ends of the support rods 10 are welded and fixed to the adjacent support plates 2. The support rods 10 can provide a good support effect for the support plates 2, thereby better supporting and protecting the user's knees.

[0049] like Figure 5As shown, the nursing component includes a plurality of channels transversely opened in the knee pad ring 1; a plurality of magnetic balls 11 are rollingly fitted in the channels, and a plurality of magnetic blocks 12 are fixedly bonded in the knee pad ring 1; the magnetic blocks 12 are evenly distributed on the outside of the channels, and the controller is used to adjust the adsorption force of the magnetic blocks 12 on the balls 11.

[0050] The knee sleeve 1 is made of cotton cloth, and elastic rings 15 are sewn on both ends of the knee sleeve 1. Cotton cloth has good comfort, air permeability and perspiration-wicking properties, which can keep the knee joint dry and comfortable, and reduce discomfort during exercise. The design of the elastic ring 15 enables the knee sleeve 1 to adapt to users of different body shapes, quickly fit the user's legs, and provide users with improved support and protection.

[0051] The data monitoring system includes a temperature monitoring module, a motion monitoring module and a limb monitoring module.

[0052] The temperature monitoring module is used to monitor the ambient temperature and the temperature of the user's knee in real time, adjust the temperature of the user's knee in real time according to the temperature of the user's knee, and provide travel suggestions for the user according to the ambient temperature. In this embodiment, the temperature monitoring module is implemented based on a temperature sensor, and the controller is used to receive the temperature value detected by the temperature sensor, and then adjust the temperature of the heating wire to provide heating care for the user's knee.

[0053] The motion monitoring module is used to monitor the user's motion state, amount of exercise and duration of exercise, and provide motion adjustment suggestions based on the user's motion state, amount of exercise and duration of exercise, combined with the temperature value change of the user's knee. In this embodiment, the motion monitoring module is implemented based on an acceleration sensor. The motion monitoring module determines whether the user is in motion, such as still, walking or running, by detecting the acceleration change of the user's body, and uses a timer to record the user's exercise duration. According to the motion acceleration (a) and the exercise duration (t), the user's amount of exercise (W) is calculated.

[0054] The exercise volume algorithm is as follows:

[0055] W = K × a × t (1).

[0056] Among them, k is the exercise coefficient designed according to the user's exercise type and user weight.

[0057] The limb monitoring module is used to detect the size of the user's legs, the current shape of the legs, and the bending angle of each leg bending, and then judge the movement state of the user's legs according to the current shape of the legs, and judge the user's movement amplitude according to the bending angle of each leg bending, and then adjust the size and angle of the support plate 2, and provide posture adjustment suggestions. In this embodiment, the limb monitoring module uses an angle sensor to detect the change of the bending angle of the legs, and the limb monitoring module uses a strain sensor to monitor the size and shape of the user's legs.

[0058] During the user's exercise, the limb monitoring module will use the angle sensor to monitor the bending angle of the user's legs, and then judge the movement state of the user's legs according to the current shape of the user's legs, and judge the user's movement amplitude according to the bending angle of each leg bending, and then adjust the size, angle and direction of the support plate 2; when the user's thigh and calf are repeatedly bent, it is judged that the user keeps moving, and the movement amplitude and speed of the user's legs are analyzed according to the maximum value of the bending angle change and the speed of the angle change. The movement monitoring module monitors the acceleration changes of the user's body based on the acceleration sensor, so as to accurately judge the user's movement speed, and adjust the direction of the current passed into the electromagnet 3 when the speed direction changes.

[0059] The specific implementation process is as follows:

[0060] like Figure 2 As shown, first, the knee pad ring 1 is worn on the user's knee to fit the user's skin, and the position of the knee pad ring 1 is adjusted so that the two groups of support plates 2 are respectively aligned with the front and back sides of the user's knee.

[0061] by Figure 3 and Figure 4 For example, suppose that initially, the user wears the knee brace 1 in a sitting position. At this time, the motion monitoring module detects through the angle sensor that the angle between the side walls of the upper and lower support plates 2 is about 90°. At this time, the angle begins to increase, and the motion monitoring module will determine that the user needs to straighten the knee. The controller will immediately control the electromagnets 3 on both sides of the user's knee to attract each other, so that the support plates 2 on the front and back of the knee fit together, and the support plate 2 on the front of the knee provides the user with the traction required for straightening, and the support plate 2 on the back of the knee provides the user with the support required for straightening, thereby assisting the user's knee to keep straight. After the user's knee is bent and straightened, the angle between the side walls of the upper and lower support plates 2 is close to 180°.

[0062] If the angle starts to decrease at this time, the motion monitoring module will determine that the user's knee begins to bend, and the controller will immediately change the direction of the current, controlling the electromagnets 3 on both sides of the user's knee to repel each other, thereby causing the upper and lower support plates 2 to bend according to the user's motion angle, while providing the knee with the traction required for bending, assisting the user's knee to bend. When the user exercises, the controller will repeatedly adjust the direction of the current, thereby adjusting the magnetism of the electromagnet 3, and adjusting the current size according to the speed of the user's leg movement, thereby adjusting the size of the electromagnetic force. The faster the movement, the greater the electromagnetic force, and the slower the movement, the smaller the electromagnetic force, thereby adapting to movements of different rhythms.

[0063] When the user's thigh and calf remain vertical for more than 5 seconds, it is determined that the user is standing; at this time, the electromagnets 3 on the front and back sides of the knee attract each other to provide support for the user.

[0064] by Figure 3 For example, during this process, when the user straightens his knee, the electromagnets 3 on the upper and lower sides attract each other, and the attraction causes the first connecting rod 5 and the second connecting rod 6 to rotate clockwise and counterclockwise around the central rod 4 respectively. Since the first connecting rod 5 and the second connecting rod 6 are respectively hinged to the fixing rod 7 adjacent thereto, the first connecting rod 5 and the second connecting rod 6 will pull the fixing rods 7 on both sides of the central rod 4 to rotate around the central rod 4 and move closer to each other. Since the fixing rod 7 is fixedly connected to the support plate 2 with bolts, the fixing rod 7 will drive the support plates 2 on both sides to move closer to each other. At the same time, the first The connecting rod 5 and the second connecting rod 6 are respectively hinged to the sliding rod 8 adjacent to them. The sliding rod 8 is limited by the slider 9 and the support plate 2. The rotation of the first connecting rod 5 and the second connecting rod 6 will pull the sliding rod 8 to move away from the electromagnet 3, thereby improving the rotation stability of the first connecting rod 5 and the second connecting rod 6, and providing better supporting force for the support plate 2. At the same time, the rotation of the first connecting rod 5 and the second connecting rod 6 will drive the sliding rod 8 to squeeze the support plate 2, thereby further driving the support plate 2 to rotate, so that the side of the support plate 2 where the electromagnet 3 is fixed is close to each other.

[0065] by Figure 3 For example, similarly, when the user bends his knees, the electromagnets 3 on the upper and lower sides repel each other, and the repulsive force causes the first connecting rod 5 and the second connecting rod 6 to rotate counterclockwise and clockwise around the center rod 4 respectively. The first connecting rod 5 and the second connecting rod 6 will push the fixed rods 7 on both sides of the center rod 4 to rotate around the center rod 4 and move away from each other, thereby generating a pulling force for the support plates 2 on both sides to move closer to each other. At the same time, the rotation of the first connecting rod 5 and the second connecting rod 6 will push the sliding rods 8 on both sides of the center rod 4 to move closer to the electromagnet 3. The sliding rod 8 will drive the slider 9 to slide and squeeze the side wall of the slide groove, thereby further driving the support plate 2 to rotate, so that the side of the support plate 2 where the electromagnet 3 is fixed moves away from each other.

[0066] During the user's exercise, a number of balls 11 will roll in channels at different heights, thereby producing a fluid massage on the user's skin; and due to the magnetic field generated by the electromagnets 3 on both sides of the user's knees, the magnetic balls 11 will roll more strongly and regularly; at the same time, the controller will also regularly adjust each magnetic block 12 to attract the balls 11; thereby, a number of balls 11 can evenly massage the user's skin, thereby improving the massage effect; and during the user's exercise, the balls 11 will constantly rub against the user's skin, and both the balls 11 and the user's skin will generate a certain amount of heat, thereby heating the user's legs and enhancing blood flow in the user's legs; heating care is provided to the user's legs while massaging them, and the two work together to further improve the user's comfort.

[0067] The present invention combines the design of the support plate 2 with the electromagnet 3, and respectively sets the two groups of support plates 2 on the front and back sides of the user's knees. When the user needs to keep the knees straight, the electromagnets 3 are used to attract each other to make the support plates 2 move to a vertical state and be fixed, thereby generating a force to assist the user in straightening the knees, and generating a reasonable supporting force after the user's knees are straightened, thereby providing the user with a standing assistance function; when the user is exercising, the controller continuously changes the direction of the current, so that the electromagnet 3 continuously generates a repulsive force and an attractive force, and then continuously provides the user with traction and supporting force during the user's exercise process to assist the user in exercising; and in this process, by detecting the user's movement amplitude and movement speed, the size of the current is adaptively adjusted, and then the size of the repulsive force and the attractive force is controlled, so as to provide different sizes, angles and directions of auxiliary forces for different exercise situations, thereby providing adaptive support and protection for the knee joint in different postures.

[0068] The present invention uses electromagnetic force as the driving force and a unique mechanical structure design, so that the support plate 2 can be rotated to different angles to provide adaptive support and protection for the user. At the same time, no additional driving device is added, which greatly reduces the overall weight of the device and does not cause a weight burden on the user's knees. Compared with the prior art, the present invention not only wraps the user's knees with a flexible knee pad ring 1 to provide support and protection for the user, but also combines a rigid support plate 2 to provide rigid support for the user's knees, which increases the support strength without affecting the user's comfort and provides a motion-assisting function.

[0069] Embodiment 2:

[0070] like Figure 5 As shown, the difference from the above-mentioned embodiment is that the channels are all wavy.

[0071] The specific implementation process is as follows: the wavy design can increase the length of the channel, so that the ball 11 has more rolling space, thereby achieving a better massage effect, increasing the friction distance, generating more heat, and producing a better massage effect and heating care effect.

[0072] Embodiment 3:

[0073] like Figure 5 As shown, the difference from the above embodiment is that a plurality of elastic protrusions are fixedly bonded to the inner bottom wall of the channel.

[0074] The specific implementation process is as follows: during the rolling of the ball 11, the ball 11 will continuously collide with the elastic bumps, thereby enhancing the rolling effect of the ball 11. At the same time, the ball 11 will continuously bounce during the rolling process, expanding the range of massage, increasing the frequency of friction, and further producing better massage effects and heating care effects.

[0075] Embodiment 4:

[0076] like Figure 5 As shown, the difference from the above embodiment is that a plurality of resin support strips 13 are vertically fixed and bonded inside the knee brace ring 1.

[0077] The specific implementation process is as follows: the resin support strip 13 can further provide support for the user's knees, and the resin support strip 13 has good elasticity, and can adapt to the movement of the user's legs while supporting the user's knees.

[0078] Embodiment 5:

[0079] like Figure 1 As shown, the difference from the above embodiment is that a knee pad 14 is fixedly bonded to the outer wall of the knee pad ring 1 near the knee, and a plurality of heating wires are fixedly bonded inside the knee pad 14, and a controller is used to control the heating temperature of the heating wires.

[0080] The specific implementation process is as follows: The design of the heating wire can further provide heating care to the user's knee area and improve the effect of heating care.

[0081] Obviously, the above embodiments are merely examples for the purpose of clear explanation, and are not intended to limit the implementation methods. For those skilled in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. The obvious changes or modifications derived therefrom are still within the scope of protection of the invention.
