Description

Technical Field

[0001] This invention generally relates to the field of massage equipment, and specifically to a knee joint massage device with multiple techniques. Background Technology

[0002] Knee massage can help relieve knee pain and stiffness, promote local blood circulation, and enhance knee joint flexibility.

[0003] Common knee massage devices on the market include low-frequency pulse massagers, air pressure massagers, thermotherapy massagers, and fascia guns. They primarily relieve and soothe knee problems through vibration, airbags, heat therapy, or pulses.

[0004] However, the massage instruments mentioned above differ significantly from traditional Chinese medicine techniques and cannot simulate the doctor's treatment methods in terms of mechanism, which results in the treatment effect not meeting expectations. Summary of the Invention

[0005] In view of the problems existing in the prior art, the present invention provides a knee joint massage device with multiple techniques, comprising: a body; a support located below the body; a moving vibration mechanism disposed within the body and connected to the support for driving the support to vibrate and displace; at least three grippers evenly arranged in a circle around the center of the support, one end of which is rotatably connected to the support, and the other end extending away from the support; and a drive mechanism fixed within the support and connected to each gripper for driving each gripper to rotate relative to the support to simulate a grasping action. By having the above-mentioned technical features, the body is fixed around the patella, and the drive mechanism drives each gripper to reciprocate on the support to simulate a grasping action, thereby grasping the patella. Combined with vibration and displacement, this simulates the patellar massage techniques of traditional Chinese medicine, such as patellar vibration, patellar pushing, and patellar scraping, thereby improving the therapeutic effect.

[0006] In some embodiments, the moving vibration mechanism includes a displacement plate; a linear mechanism fixed at both ends of the displacement plate and connected to the machine body, used to drive the displacement plate to reciprocate in a linear direction within the machine body; and a vibration motor, the main body of which is fixed to the displacement plate, with its output shaft passing through the displacement plate and connected to the support. Thus, the vibration motor can drive the support to vibrate, thereby causing the grippers to perform vibration massage while gripping and massaging. The linear mechanism, connected to the displacement plate, allows the grippers to move in a linear direction while gripping, vibrating, and massaging, thereby expanding the massage range and improving the massage effect.

[0007] In some embodiments, the drive mechanism includes a tightening motor fixed to the center of the support on the side away from the grippers and facing the grippers; a threaded shaft coaxially fixed to the output shaft of the tightening motor; a movable disc coaxially passing through the threaded shaft and threadedly connected to the threaded shaft; and connecting rods, the number of which corresponds one-to-one with the number of grippers, with both ends of the connecting rods rotatably connected to the movable disc and the grippers respectively; the output shaft of the vibration motor is detachably fixedly connected to the tightening motor. Thus, when the tightening motor starts, it drives the threaded shaft to rotate. Through the threaded connection between the threaded shaft and the movable disc, the movable disc is displaced along the length of the threaded shaft under limited rotation. Since the movable disc is rotatably connected to each gripper, the displacement of the movable disc simultaneously drives each gripper to swing. The simultaneous swinging of all grippers simulates a hand grasping motion, thereby simulating traditional Chinese medicine techniques and improving the massage effect.

[0008] In some embodiments, the tightening motor is equipped with a torque sensor. This improves safety during the massage process. When the tightening motor is working, feedback from the gripper resistance causes the motor to reverse, achieving the massage purpose without posing any risks to the massage area, thus ensuring the overall safety of the massage.

[0009] In some embodiments, the gripper is an arc-shaped claw with its concave side facing the center of the support. Thus, the shape of the gripper simulates the bending motion of a finger during massage, allowing for a closer fit to the massage area and increasing the gripping range, thereby improving the massage effect.

[0010] In some embodiments, four grippers are provided. This simulates the tactile sensation of finger massage, and the combined action of the four grippers makes the massage area more targeted, thus improving the massage effect.

[0011] In some embodiments, each of the grippers is provided with a rounded gripper head. This increases the contact area with the body, reduces local pressure, further reduces pain during the massage process, and improves the static or dynamic safety of the device.

[0012] It should be understood that the description in the Summary of the Invention is not intended to limit the key or essential features of the embodiments of this disclosure, nor is it intended to restrict the scope of this disclosure. Other features of this disclosure will become readily apparent from the following description. Attached Figure Description

[0019] The preferred embodiments (or implementation methods) of the present invention will now be described in detail with reference to the accompanying drawings.

[0020] This invention provides a knee joint massage device with multiple techniques. The device includes a body 1 and a support 3 connected to the bottom of the body 1. A movable vibration mechanism 2 is installed inside the body 1 to drive the support 3 to move and vibrate. Four grippers 4 are located on the side of the support 3 opposite to the body 1. One end of each gripper 4 is rotatably connected to the support 3, and the other end of the support 3 extends towards the support 3. The four grippers 4 are evenly distributed in a circle around the center of the support 3. A drive mechanism 5 is also provided on the side of the support 3 opposite to the grippers 4, simultaneously driving the four grippers 4 to perform a grasping action. By controlling the reciprocating swing of the four grippers 4 through the drive mechanism 5, the grasping action of the fingers is simulated. Combined with the displacement and vibration of the movable vibration mechanism 2, the grippers 4 simulate the patellar massage techniques of traditional Chinese medicine, such as patellar tapping, patellar pushing, and patellar scraping, thereby improving the therapeutic effect.

[0021] The following is for reference. Figures 1-4 This invention describes a knee joint massage device with multiple manual techniques.

[0022] Figure 1 A schematic diagram of the overall structure of a multi-manual knee joint massage device according to an embodiment of the present invention is shown. (Reference) Figure 1 As shown, the knee joint massage device with multiple techniques provided in this embodiment includes a fixing part 61 and a massage part 62 connected to one side of the fixing part 61.

[0023] Figure 2 A schematic diagram of the internal structure of the fixing part in a knee joint multi-manual massage device according to an embodiment of the present invention is shown. (Reference) Figure 2 As shown, the fixing part 61 includes a body 1 and a moving vibration mechanism 2 located inside the body 1. The body 1 is a shell that can accommodate an electrically driven device to enable the entire massage device to work normally. A mounting hole is provided on one side to fix the massage device in place and ensure the stability of the massage device during operation.

[0024] The moving vibration mechanism 2 includes a displacement plate 21 located in the middle of the body 1, with space between its two sides and the side walls of the body 1 to allow for normal movement of the displacement plate 21. A vibration motor 23 is mounted on the displacement plate 21, with its main body fixed to the displacement plate 21 and its output shaft extending out of the displacement plate 21 and facing downwards towards the body 1. A linear mechanism 22 is mounted at each end of the displacement plate 21. The linear mechanism 22 can be a screw drive, consisting of a guide rail, a slider, a screw, and a motor. In this embodiment, the guide rail is fixed inside the body 1, the slider slides along the length of the guide rail and is fixed to the displacement plate 21, and the screw is arranged along the length of the guide rail inside the body 1, with both ends rotatably connected to the body 1. The screw passes through the slider and is threadedly connected to the slider, and a motor is mounted at one end of the screw. Starting the motor drives the screw to rotate, and through the threaded connection between the slider and the screw, the slider moves back and forth on the guide rail, thus controlling the displacement plate 21. The linear mechanism 22 can also be a gear transmission structure, mainly composed of a guide rail, a slider, a motor, gears, and a rack. In this embodiment, the guide rail is fixed inside the machine body 1, the slider slides along the length of the guide rail and is connected to the guide rail, and the slider and the displacement plate 21 are fixed to each other. The motor is fixed on the slider, and its output shaft is coaxially fixed with a gear. The rack is fixed on the guide rail along the length of the guide rail and meshes with the gear. When the motor starts, the meshing of the gear and rack drives the slider to move on the guide rail, thereby realizing the control of the displacement plate 21.

[0025] Figure 3 A schematic diagram of the massage unit 62 of a multi-manual knee joint massage device according to an embodiment of the present invention is shown. (Reference) Figure 3 As shown, the massage unit 62 includes a support 3, which is a plate used to support the entire massage unit 62; four grippers 4 are connected to its bottom, each gripper being an arc-shaped claw used to simulate the shape of a static finger and improve the fit with the massage area. The grippers 4 are positioned at the center of the support 3, with one end rotatably connected to the support 3 and the other end facing the support 3. The four grippers 4 are evenly distributed in a circle around the center of the support 3, and the curved part of each gripper 4 faces the central area of ​​the support 3. The support 3 is also provided with a drive mechanism 5 that simultaneously drives the four grippers 4 to rotate synchronously.

[0026] Figure 4A schematic diagram of the drive mechanism 5 in a multi-manual knee massage device according to an embodiment of the present invention is shown. (See reference) Figure 4 As shown, the drive mechanism 5 includes a tightening motor 51 fixed on the side of the bracket 3 away from the gripper 4. The main body of the tightening motor 51 is fixed in the central area of ​​the bracket 3, and its output shaft passes through the bracket 3. The tightening motor 51 is detachably and fixedly connected to the output shaft of the vibration motor 23 to realize the mutual connection between the fixing part 61 and the massage part 62. The output shaft of the tightening motor 51 is also coaxially fixed to a threaded shaft 52. A movable disk 53 is also threaded through the threaded shaft 52 and threadedly connected to the movable disk 53. A connecting rod 54 is provided in the adjacent area of ​​the movable disk 53 and each gripper 4. One end of the connecting rod 54 is rotatably connected to the movable disk 53, and the other end of the connecting rod 54 is rotatably connected to the corresponding gripper 4. During operation, the tightening motor 51 drives the threaded shaft 52 to rotate. The threaded shaft 52 is connected to the moving disk 53 by threads. Under the limit of the four connecting rods 54, the moving disk 53 is moved away from the bracket 3, and the four connecting rods 54 are moved, thereby driving the four grippers 4 to rotate on the bracket 3. The forward or reverse rotation of the tightening motor 51 causes the four grippers 4 to swing back and forth to simulate the gripping state of fingers.

[0027] Because the tightening motor 51 has a torque sensor inside, if the resistance during the gripping and massage process exceeds the set torque value, it will stop rotating or rotate in the opposite direction to avoid excessive pressure on the massage area and causing damage. Furthermore, the ends of the grippers 4 are all rounded, which increases the contact area with the massage area, distributes pressure, and reduces pain; it also ensures the smoothness and safety of the gripper 4's movement. In conjunction with the moving vibration mechanism 2, the grippers 4 simulate vibration and movement while gripping, increasing the massage range and simulating the techniques of patellar vibration, patellar pushing, and patellar scraping in traditional Chinese medicine, effectively improving the massage effect. Due to individual differences in the knee joints of different patients, the massage unit 62 can be replaced through the detachable connection between the tightening motor 51 and the vibration motor 23. This allows for adjustment of the appropriate gripper 4 size and the use of gripper heads of different hardness and shape to ensure the effectiveness of the massage.

For example, "connection" can be a fixed connection, a detachable connection, or an integral connection; it can be a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in this application according to the specific circumstances.
