Thus, features defined with "first" and "second" may explicitly or implicitly include one or more of such features. In the description of the embodiments of the present invention, "a plurality of" means two or more, unless otherwise specifically defined.

[0032] In the embodiments of the present invention, unless otherwise clearly specified and defined, terms such as "installed", "connected", "coupled", "fixed", etc. should be understood in a broad sense. For example, it may be a fixed connection, a detachable connection, or integrated; it may be a mechanical connection or an electrical connection; it may be directly connected or indirectly connected through an intermediate medium, and it may be the communication inside two elements or the interaction relationship between two elements. For those of ordinary skill in the art, the specific meanings of the above terms in the embodiments of the present invention can be understood according to specific circumstances.

[0033] In one embodiment of the present invention, as Figures 1 to 9 shown, a massage and physiotherapy device is provided, which includes a mounting bracket 1, and a first massage part 10 and a second massage part 20 sequentially arranged along the axis of the mounting bracket 1. The first massage part 10 includes a massage head 30 for massage, a clamping mechanism 40 for driving the massage head 30 to move at an angle with respect to the axis of the mounting bracket 1, and a driving mechanism 50 for driving the clamping mechanism 40 to move horizontally along the axis of the mounting bracket 1; the second massage part 20 is provided with a massage cavity 21 penetrating axially, and the massage cavity 21 forms a massage area for massage, wherein the massage cavity 21 can allow a human arm to penetrate.

[0034] Specifically, the mounting bracket 1 is the support structure of the entire massage and physiotherapy device, providing a mounting foundation for other components. The first massage part 10 is located at a position close to one end of the mounting bracket 1, while the second massage part 20 is on the axial extension line of the first massage part 10. They have a relatively fixed positional relationship on the mounting bracket 1, ensuring the structural stability of the entire massage and physiotherapy device during operation. In the first massage part 10, the massage head 30 is mounted on the clamping mechanism 40, and the clamping mechanism 40 is connected to the driving mechanism 50. The driving mechanism 50 is mounted on the mounting bracket 1 and can drive the clamping mechanism 40 to move horizontally along the axis of the mounting bracket 1. At the same time, the clamping mechanism 40 is connected to the massage head 30 through its own mechanical structure. It not only provides support for the massage head 30 but also ensures that the massage head 30 can move horizontally along the radial direction of the mounting bracket 1 under its drive. The second massage part 20 is arranged behind the first massage part 10 (along the axis of the mounting bracket 1). The position and shape of the massage cavity 21 on it are designed according to the physiological structure of the body parts to be massaged, such as the human arm, so that the body part can enter the massage cavity 21 to receive the massage of the second massage part 20. The second massage part 20 also has a corresponding mounting structure with the mounting bracket 1 to ensure that it is firmly mounted on the mounting bracket 1 and in a suitable position to cooperate with the first massage part 10.

[0035] When the massage and physiotherapy device is started, the driving mechanism 50 starts to work first, driving the clamping mechanism 40 to move horizontally along the axis of the mounting bracket 1. This can enable the massage head 30 to cover a larger range in the axial direction to meet the massage needs of different lengths of arms.

[0036] At the same time, the clamping mechanism 40 also starts to work according to the set program or the user's operation. The massage head 30 can stably move horizontally along the radial direction of the mounting bracket 1 under its drive. This radial movement can adjust the position of the massage head 30 relative to the human arm to meet the massage needs of different arm thicknesses and different muscle positions. By precisely controlling the movement of the clamping mechanism 40, the massage head 30 can be adjusted to a suitable position, providing a suitable initial massage position for the massage head 30 so that the massage head 30 can fit different parts of the arm.

[0037] When the massage head 30 reaches the appropriate position, the massage head 30 starts to perform massage actions. The massage head 30 can be equipped with a vibration motor inside. The rotation of the motor generates vibration to achieve the massage of the human arm. Among them, the massage head 30 can rotate and massage by rubbing against the human skin on the clamping mechanism 40, and can also achieve the self-rotation function through an internally set driving source. In addition, it can also drive a cam mechanism through a motor to make the massage head 30 perform reciprocating movements to simulate the actions of manual kneading. Or adopt other massage methods, such as generating pulsed massage actions by electromagnetic driving of the massage head 30, etc.

[0038] For the second massage part 20, when a human arm or other body part to be massaged enters its massage cavity 21, the second massage part 20 will start working according to the internal massage mechanism. It can massage the human body in the massage cavity 21 by means of structures such as air bags or massage balls arranged on the inner wall of the massage cavity 21 through inflation, deflation or rotation. For example, when an air bag is used internally, an air pump is used to inflate and deflate the air bag, and the expansion and contraction of the air bag will produce squeezing and relaxing massage effects on the body part; if a massage ball is used, the massage ball can be driven by a motor to rotate or vibrate to massage the body part. Moreover, the second massage part 20 is made of flexible material, which can better fit the shape of the human arm and increase the comfort during massage. The second massage part 20 is connected to a driving structure, and the driving structure can be a vibration source that provides vibration for the second massage part 20 / a rotational power source that makes the second massage part 20 rotate / a power source that makes the second massage part 20 reciprocate axially / a negative pressure structure that generates negative pressure in the massage cavity 21 of the second massage part 20, etc.

[0039] Through the cooperation of the first massage part 10 and the second massage part 20, this massage and physiotherapy instrument realizes multi-dimensional massage of body parts such as the human arm, providing a more rich and diverse massage experience. The driving mechanism 50 and the clamping mechanism 40 in the first massage part 10 can flexibly adjust the position of the massage head 30, enabling the massage head 30 to move axially and radially, so as to be accurately adjusted according to the arm length and thickness of different users, improving the adaptability and personalization of massage, expanding the scope of applicable people, and better meeting the needs of different users. The massage head 30 can adopt various massage methods, increasing the richness and effectiveness of massage, and effectively solving the problem of single massage effect of previous massage and physiotherapy instruments. For example, through the combination of various massage methods such as vibration, kneading, and pulse, muscles can be more deeply relaxed, blood circulation can be promoted, muscle fatigue and pain can be relieved, and the user experience can be improved. The design of the massage cavity 21 of the second massage part 20 can better position and fix the body part, improving the accuracy and effect of massage. At the same time, its internal massage mechanism can perform targeted massage according to different body parts, effectively massage specific areas (such as wrists, elbows, etc.), and cooperate with the first massage part 10 to form a relatively complete arm massage system, which can better provide users with comprehensive massage and physiotherapy services, improve the comprehensiveness and integrity of massage, and further enhance the comfort and satisfaction of users.

[0040] Furthermore, the driving mechanism 50 is disposed on the axis of the mounting bracket 1. Specifically, the driving mechanism 50 is arranged on the axis of the mounting bracket 1 so that the first massage part 10 can move precisely along the axial direction, better adapting to the differences in the arm lengths of different users, ensuring that the massage head 30 can cover the entire arm length range for massage, greatly improving the applicability of the massage physiotherapy device, and meeting the personalized needs of different users.

[0041] Furthermore, a partition 11 is provided on the mounting bracket 1. The second massage part 20 and the massage head 30 are arranged above the partition 11, and the driving mechanism 50 and the clamping mechanism 40 are disposed below the partition 11; a clearance groove 111 is provided on the partition 11, and the clearance groove 111 is located below the massage head 30. Specifically, the partition 11 is fixedly installed on the mounting bracket 1, which divides the internal space of the mounting bracket 1 into upper and lower parts. The partition 11 can be connected to the mounting bracket 1 by means of welding, screwing or clamping, etc., forming a stable structure, providing support and positioning basis for the layout of other components. The second massage part 20 is arranged above the partition 11, and it can be connected to the partition 11 through a support structure or directly, ensuring its stable position. For example, the bottom of the second massage part 20 can be fixed on the upper surface of the partition 11 by bolts or a clamping groove structure, ensuring that it will not displace during use. The position of the second massage part 20 is determined according to the actual needs of massaging the human arm, facilitating the arm to enter the internal massage cavity 21 for massage operation. Its height and angle on the mounting bracket 1 should match the comfortable position of the human arm placement to ensure the massage effect and user experience. The positions of the driving mechanism 50 and the clamping mechanism 40 are arranged below the partition 11, which not only facilitates hiding and protecting the internal transmission components, but also can utilize the partition 11 as a support structure to optimize the overall space layout of the device. The clearance groove 111 on the partition 11 is located below the massage head 30, which provides spatial clearance for the movement of the massage head 30. The shape and size of the clearance groove 111 are designed according to the movement range and trajectory of the massage head 30 to ensure that the massage head 30 will not interfere with the partition 11 when moving radially horizontally. The clearance groove 111 can be rectangular, circular or other shapes, and its position and size are precisely matched with the movement range of the massage head 30 to ensure that the massage head 30 can move smoothly above the partition 11 during operation.

[0042] In this example, as Figure 6As shown, the massage head 30 includes a first motor 31 and a rolling member 32 driven by the first motor 31. The first motor 31 is disposed on the mobile end of the clamping mechanism 40, and the rolling member 32 is connected to the output end of the first motor 31. Specifically, the first motor 31 is a vibration motor or a direct drive motor. The first motor 31 can be firmly mounted on the mobile end of the clamping mechanism 40 by bolts, buckles or other fixing devices to ensure that it will not loosen or displace during the operation of the massage physiotherapy device. The mobile end of the clamping mechanism 40 is responsible for driving the first motor 31 to move in the radial horizontal direction of the mounting bracket 1, so that the first motor 31 can adjust its position following the movement of the clamping mechanism 40 to meet the need for massaging different parts of the human arm. If the first motor 31 is a direct drive motor, the rolling member 32 may be directly mounted on the output shaft of the motor and is reliably fixed circumferentially by keys, pins, etc. to ensure that the power of the motor can be effectively transmitted to the rolling member 32. If the first motor 31 is a vibration motor, the rolling member 32 can be connected to the vibrating part of the motor, and the vibration generated by the motor is transmitted to the rolling member 32 through a specific connection structure, causing the rolling member 32 to generate a corresponding vibration effect. When the rolling member 32 is driven by the vibration motor, it will contact the arm muscles in a high-frequency vibration manner. Through the impact force and frequency change of the vibration, the muscle fibers are stimulated to achieve the effect of relaxation and soothing. After the rolling member 32 is connected to the output end of the first motor 31, it can move under the drive of the first motor 31, thereby realizing the massage operation on the human arm.

[0043] Further, the massage head 30 further includes a flexible member 33 made of a flexible material, and the flexible member 33 is sleeved outside the rolling member 32. Specifically, the flexible member 33 is disposed on the periphery of the rolling member 32. The flexible member 33 sleeved on the surface of the rolling member 32 can improve the massage effect. For example, the flexible member 33 with protrusions or textures on the surface can increase the friction with the arm skin, better simulate the feel of manual massage, and produce more effective stimulation to the muscles.

[0044] Further, the rolling member 32 is provided in a cylindrical shape, and the diameter of the middle part of the rolling member 32 is smaller than that of both ends. Specifically, during the massage process, the rolling member 32 contacts the human arm. Its special shape (the diameter of the middle part is smaller than that of both ends) enables it to better fit the contour of the human arm. The muscle thickness and shape of different parts of the arm are different. This special-shaped rolling member 32 can closely contact at different positions such as the outer side and the inner side of the arm, ensuring effective massage of every muscle, improving the comprehensiveness and pertinence of the massage, and further enhancing the massage effect. This contact method can be adaptively adjusted according to the muscle thickness and shape of different parts of the arm to better fit the arm contour.

[0045] In this example, as Figures 3 to 6As shown in the figure, the clamping mechanism 40 includes a substrate 41, a clamping power element 42, and a first transmission assembly 43; the substrate 41 is connected to the moving end of the driving mechanism 50; the clamping power element 42 is arranged on the substrate 41; the first transmission assembly 43 connects the output end of the clamping power element 42 and the massage head 30, and the massage head 30 realizes horizontal movement along the radial direction of the mounting bracket 1 under the action of the clamping power element 42 and the first transmission assembly 43. Specifically, the moving end of the driving mechanism 50 serves as the power output end, driving the substrate 41 and other components mounted on the substrate 41 to move together, enabling the entire clamping mechanism 40 to adjust its position in the axial direction to adapt to the lengths of different users' arms and massage requirements. In the structure of the entire massage physiotherapy device, the clamping mechanism 40 is located on one side of the mounting bracket 1, and the substrate 41 serves as the basic support component of the clamping mechanism 40, carrying the clamping power element 42 and the first transmission assembly 43. The driving mechanism 50 is on the axis of the mounting bracket 1, driving the entire clamping mechanism 40 to move axially; while the clamping mechanism 40 itself drives the massage head 30 to move horizontally in the radial direction of the mounting bracket 1 through the clamping power element 42 and the first transmission assembly 43. Under the action of the clamping mechanism 40, the massage head 30 can adjust its position in three-dimensional space to achieve precise massage of different parts of the human arm. The second massage part 20 is arranged on the mounting bracket 1 and is arranged axially in sequence with the first massage part 10 (including the massage head 30 and the clamping mechanism 40, etc.) to jointly complete the massage work on the human arm.

[0046] Furthermore, the clamping power element 42 includes a clamping motor 421 and a transmission 422; both the clamping motor 421 and the transmission 422 are mounted on the substrate 41, and the transmission 422 connects the clamping motor 421 and the first transmission assembly 43. Specifically, the connection manner between the clamping motor 421, the transmission 422 and the substrate 41 can be through bolt fastening to ensure that there is no loosening or displacement during the operation of the massage physiotherapy device. One end of the transmission 422 is connected to the output shaft of the clamping motor 421, and the connection manner can adopt a coupling to ensure the coaxiality between the two and achieve efficient power transmission. The other end of the transmission 422 is connected to the first transmission assembly 43, and the power adjusted by the transmission 422 is transmitted to the first transmission assembly 43 through transmission components such as gears 431, chains or belts. This connection relationship enables the transmission 422 to play a role in adjusting the speed and torque between the clamping motor 421 and the first transmission assembly 43 to meet the different movement requirements of the massage head 30. The substrate 41 is connected to the moving end of the driving mechanism 50, and driven by the driving mechanism 50, the substrate 41 can move axially along the mounting bracket 1. The clamping motor 421, the transmission 422 mounted on the substrate 41, and the massage head 30 connected through the first transmission assembly 43 can, while realizing axial movement, also drive the massage head 30 to move horizontally in the radial direction of the mounting bracket 1 through the driving of the clamping power element 42.

[0047] Furthermore, the first transmission assembly 43 includes a gear 431, a first rack 432, and a second rack 433; the gear 431 is connected to the output end of the clamping power element 42, and the first rack 432 and the second rack 433 are respectively arranged above and below and both mesh with the gear 431; massage heads 30 are arranged on both the first rack 432 and the second rack 433. Specifically, the gear 431 is tightly connected to the output end of the clamping power element 42 (the clamping motor 421 passes through the transmission 422), usually by means of key connection or coupling connection, to ensure that power can be stably and efficiently transmitted from the clamping power element 42 to the gear 431. In the structure of the entire massage and physiotherapy device, the clamping power element 42 (the clamping motor 421 and the transmission 422) is installed on the substrate 41, and the gear 431 is connected to the output end of the clamping power element 42 and is located near the substrate 41. The first rack 432 and the second rack 433 are arranged in parallel, respectively above and below the gear 431, and mesh with the gear 431. The substrate 41 is connected to the mobile end of the driving mechanism 50, so that the entire clamping mechanism 40 (including the gear 431, the first rack 432, the second rack 433, and the massage head 30) can move axially along the mounting bracket 1 under the drive of the driving mechanism 50. The massage heads 30 on the first rack 432 and the second rack 433 can move horizontally in the radial direction of the mounting bracket 1 under the drive of the gear 431, and cooperate with the second massage part 20 to achieve comprehensive massage of the human arm.

[0048] Furthermore, an extension rod 434 is arranged on the side of the gear 431 facing away from the clamping power element 42, and one end of the extension rod 434 sequentially passes through the substrate 41 and the mounting bracket 1. Specifically, the clamping distance between the two massage heads 30 can be manually adjusted through the extension rod 434.

[0049] Furthermore, a chute 411 is also arranged on the substrate 41, a guide rail 412 is horizontally arranged in the chute 411, and one end of the massage head 30 extends into the chute 411 and is slidably connected to the guide rail 412. Specifically, the massage head 30 can move within the chute 411 area of the substrate 41 through the sliding connection with the guide rail 412. The driving mechanism 50 is connected to the substrate 41 and drives the entire clamping mechanism 40 to move axially along the mounting bracket 1. The guide rail 412 provides accurate guidance for the movement of the massage head 30, ensuring that the massage head 30 can accurately move in the radial direction of the mounting bracket 1 to achieve precise positioning and massage of different parts of the human arm.

[0050] In this example, as Figures 3 to 4 and Figures 7 to 9As shown, the driving mechanism 50 includes a driving component 51, a second transmission component 52, and a slider 53; the output end of the driving component 51 is connected to the second transmission component 52; the slider 53 is connected to the second transmission component 52, and the slider 53 can be driven to move horizontally along the axis of the mounting bracket 1. Specifically, the second transmission component 52 is connected between the driving component 51 and the slider 53, playing a role in transmitting and converting power. The slider 53 is connected to the substrate 41 (because the substrate 41 is connected to the mobile end of the driving mechanism 50), and the clamping mechanism 40 is installed on the substrate 41 and moves along the axis of the mounting bracket 1 as the slider 53 moves. The second massage part 20 is arranged on the mounting bracket 1 and works together with the first massage part 10 (including the massage head 30, the clamping mechanism 40, etc.) to jointly complete the massage task of the human arm.

[0051] Furthermore, the driving component 51 includes a driving motor 511 and a gearbox 512. Both the driving motor 511 and the gearbox 512 are arranged on the mounting bracket 1, and the gearbox 512 is connected to the driving motor 511 and the second transmission component 52. Specifically, one end of the gearbox 512 is connected to the output shaft of the driving motor 511, and the connection method usually uses a coupling. The coupling can ensure the coaxiality between the two, reduce the vibration and offset during power transmission, and achieve efficient power transmission. The other end of the gearbox 512 is connected to the second transmission component 52, transmitting the power adjusted by the gearbox 512 to the second transmission component 52.

[0052] Further, the second transmission assembly 52 includes a screw 521 and a sleeve 522; the screw 521 is arranged in the sleeve 522, and the sleeve 522 is provided with a transverse groove 5221 extending in the axial direction. The slider 53 is sleeved outside the sleeve 522; the screw 521 is connected to the output end of the driving assembly 51, and one end of the slider 53 is limited in the thread groove 5211 of the screw 521. Specifically, the screw 521 is arranged inside the sleeve 522, and there is a certain gap between the screw 521 and the sleeve 522 to ensure that the screw 521 can rotate freely in the sleeve 522. The sleeve 522 is provided with a transverse groove 5221 extending in the axial direction, and the transverse groove 5221 provides a structural basis for subsequent transmission and motion control. The slider 53 and the sleeve 522 are clearance-matched, which can not only ensure that the slider 53 can move axially relative to the sleeve 522, but also prevent the slider 53 from shaking too much during the movement. One end of the slider 53 is limited in the thread groove 5211 of the screw 521, so that a threaded transmission relationship is formed between the slider 53 and the screw 521. At the same time, there is also a certain relationship between the slider 53 and the transverse groove 5221 of the sleeve 522, and the slider 53 will be constrained and guided by the transverse groove 5221 when moving. The second transmission component 52 adopts the structure of the screw 521 and the sleeve 522, which can realize the precise axial movement of the slider 53, so that the position adjustment of the massage head 30 in the axial direction of the mounting bracket 1 is more accurate. This precise control capability can meet the personalized needs of different users for massage positions, perform accurate massage operations on different parts of the human arm, and improve the pertinence and effectiveness of the massage. The structure of the second transmission component 52 is relatively compact, the screw 521 is arranged in the sleeve 522, and the slider 53 is sleeved outside the sleeve 522. This layout makes reasonable use of space and reduces the volume of the device. At the same time, the connection method between the components is simple, which is convenient for installation and disassembly. During equipment maintenance, the screw 521, sleeve 522, slider 53 and other components can be inspected, cleaned and replaced relatively conveniently, which reduces the difficulty and cost of maintenance and improves the maintainability of the equipment.

[0053] Further, the slider 53 includes a sliding portion 531, a connecting portion 532, and a guiding portion 533; one end of the connecting portion 532 is connected to the sliding portion 531, and the other end is connected to the clamping mechanism 40; the sliding portion 531 is sleeved outside the sleeve 522; the guiding portion 533 is connected to the sliding portion 531 and one end thereof passes through the transverse groove 5221 and is limited in the threaded groove 5211. Specifically, one end of the connecting portion 532 is tightly connected to the sliding portion 531, and the other end is connected to the substrate 41 in the clamping mechanism 40. This connection ensures that the slider 53 can stably transmit the power of the driving mechanism 50 to the clamping mechanism 40. The guiding portion 533 is connected to the sliding portion 531, and its position is designed to cooperate with the transverse groove 5221 on the sleeve 522 and the threaded groove 5211 of the screw 521. One end passes through the transverse groove 5221 of the sleeve 522 and is embedded in the threaded groove 5211 of the screw 521, forming a key structure for guiding and transmission. The sliding portion 531 is sleeved outside the sleeve 522, and there is a clearance fit between them, which not only ensures that the sliding portion 531 can slide axially relative to the sleeve 522 smoothly, but also limits its radial wobbling, thus ensuring the stability of the movement of the slider 53. The guiding portion 533 passes through the transverse groove 5221 of the sleeve 522 and is limited in the threaded groove 5211 of the screw 521, so that a threaded transmission relationship is formed between the slider 53 and the screw 521. At the same time, the transverse groove 5221 plays a guiding role for the guiding portion 533, ensuring that the slider 53 can only move along the axial direction of the sleeve 522. When the screw 521 rotates, since the guiding portion 533 is limited in the threaded groove 5211 of the screw 521, the rotational movement of the screw 521 will act on the guiding portion 533 through the thread, and then drive the whole slider 53 to have a movement trend along the axial direction of the screw 521. At the same time, the transverse groove 5221 on the sleeve 522 plays a limiting role for the guiding portion 533, so that the slider 53 can only move along the axial direction of the sleeve 522, thereby converting the rotational movement of the screw 521 into a linear movement of the slider 53. By controlling the operation of the driving component 51, the rotation speed and rotation direction of the screw 521 can be adjusted, and then the moving speed and direction of the slider 53 can be accurately controlled to achieve precise adjustment of the position of the massage head 30.

[0054] Furthermore, one end of the guiding portion 533 extending into the thread groove 5211 is arranged in an arc shape. Specifically, one end of the guiding portion 533 extending into the thread groove 5211 of the screw rod 521 is arranged in an arc shape. This shape design enables it to better fit with the thread groove 5211 of the screw rod 521. The connection between the guiding portion 533 and the screw rod 521 is achieved by embedding the arc-shaped end portion into the thread groove 5211, forming a key connection point for the screw drive. The arc-shaped end portion can smoothly slide within the thread groove 5211. Meanwhile, when the screw rod 521 rotates, it can effectively convert the rotational motion of the screw rod 521 into the linear motion of the guiding portion 533 and the entire slider 53. The good fit between the arc-shaped end portion of the guiding portion 533 and the thread groove 5211 of the screw rod 521 reduces friction and jamming during the transmission process, making the power transmission smoother. Since the contact between the guiding portion 533 and the thread groove 5211 of the screw rod 521 is smoother, wear and fatigue are reduced, extending the service life of the guiding portion 533 and the screw rod 521. At the same time, the stable motion state also reduces the damage risk of other related components, reduces the maintenance cost and downtime of the equipment, and improves the use efficiency and economic benefits of the massage and physiotherapy device.

[0055] Furthermore, the cross-section of the sleeve 522 along the radial direction is arranged in a regular hexagon shape. Specifically, the cross-section of the sleeve 522 along the radial direction being arranged in a regular hexagon shape can play a good guiding and limiting role for the guiding portion 533, ensuring that the guiding portion 533 can only move along the axial direction of the sleeve 522, restricting its freedom in other directions, and guaranteeing the stability and accuracy of the movement of the slider 53.

[0056] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, and improvements made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
