Description

Technical Field

[0001] The present invention relates to the technical field of massage equipment, in particular to a massage movement and a massage arm thereof. Background Art

[0002] In the field of 3D massage movement, the core component of massage equipment, the existing design scheme has obvious limitations in the structure of massage arm. In order to achieve a certain 3D ejection force, the traditional approach mainly relies on a single ball fixed massage arm or a double ball fixed massage arm structure.

[0003] Although the design of a single ball fixed massage arm can achieve basic massage functions to a certain extent, due to the presence of only one fixed massage ball and the lack of auxiliary massage function of the lower ball arm, the human body massage area that can be covered and acted on at the same time is extremely limited. This not only fails to fully meet the user's demand for comprehensive massage, but also greatly reduces the massage effect, resulting in a poor overall user experience.

[0004] The dual-ball fixed massage arm also faces severe problems in practical applications. When performing the 3D ejection action, the upper and lower massage balls will be ejected outward at the same time. In some local positions, due to the relatively rigid ejection method of the lower ball arm, lack of flexibility and adaptability, it often gives users an unpleasant feeling of being too hard, seriously affecting the user's comfort during the massage process, and may even make some users resist massage, greatly limiting the market competitiveness and user acceptance of existing 3D massage movements.

[0005] As consumers' requirements for massage quality and comfort continue to increase, and the massage equipment market becomes increasingly competitive, these existing massage arm structural defects urgently need to be effectively resolved to promote further development and innovation of massage movement technology. Summary of the invention

[0006] A major advantage of the present invention is that it provides a massage movement and a massage arm thereof, wherein the massage arm comprises an upper ball arm and a lower ball arm, the upper ball arm being a fixed structure, and the lower ball arm being a movable structure. While ensuring that the upper ball can maintain sufficient massage pushing force to meet the needs of deep massage and effective stimulation of human muscles, the present invention focuses on solving the problem of the lower ball arm feeling too hard during the massage process due to unreasonable ejection method, thereby significantly improving the overall comfort and experience of users when receiving 3D massage, enhancing the competitiveness of the product in the market, and providing users with better-quality and more humane massage services.

[0007] Another advantage of the present invention is that it provides a massage movement and a massage arm thereof, wherein the massage arm has a separate upper and lower ball arm structure, and the upper ball is fixed to ensure that effective massage strength can be continuously and stably provided during the massage process, and key acupuncture points and muscle groups of the human body are accurately stimulated and massaged, giving full play to the advantages of traditional single-ball or double-ball fixed massage arms in terms of massage strength. At the same time, the lower ball arm can be designed to rotate up and down in accordance with the curve of the human body, which greatly expands the coverage area of ​​the massage. Compared with the single-ball fixed massage arm, it can act more comprehensively on different parts of the human body and muscle contours, effectively making up for the defect of insufficient massage area, and achieving a full range of multi-level massage effects.

[0008] Another advantage of the present invention is that it provides a massage movement and a massage arm thereof, wherein the massage arm is designed with an adaptive rotation of the lower ball arm, and during the 3D ejection process, the lower ball arm can automatically adjust the ejection angle and strength according to the curves and muscle elasticity of different parts of the human body, thereby avoiding the discomfort caused by the rigid ejection of the lower ball arm of the traditional double-ball fixed massage arm. This adaptive mechanism makes the massage process softer and more natural, highly consistent with the physiological structure and massage needs of the human body, and brings users an unprecedented comfortable massage experience, significantly improving users' satisfaction and acceptance of the 3D massage movement.

[0009] Another advantage of the present invention is that it provides a massage movement and a massage arm thereof, wherein the upper and lower ball arm separate arm structure of the massage arm achieves an optimization upgrade of the traditional massage arm structure without adding too many complex components and costs. Its simple and ingenious design not only solves the key problems of the prior art, but also provides convenience for subsequent production and maintenance. During the production process, the structure is easy to assemble and debug, and can effectively improve production efficiency and product quality stability; during use, it has high reliability, reduces the risk of failure caused by unreasonable structure, reduces maintenance costs, and has good economic benefits and practical value.

[0026] The following description is used to disclose the present invention so that those skilled in the art can implement the present invention. The preferred embodiments described below are only examples, and those skilled in the art can think of other obvious variations. The basic principles of the present invention defined in the following description can be applied to other embodiments, variations, improvements, equivalents, and other technical solutions that do not deviate from the spirit and scope of the present invention.

[0027] Those skilled in the art should understand that, in the disclosure of the present invention, the terms "longitudinal", "lateral", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside" and the like indicating the orientation or position relationship are based on the orientation or position relationship shown in the drawings, which are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operate in a specific orientation. Therefore, the above terms should not be understood as limiting the present invention.

[0028] It is to be understood that the term "one" should be understood as "at least one" or "one or more", that is, in one embodiment, the number of an element may be one, while in another embodiment, the number of the element may be multiple, and the term "one" should not be understood as a limitation on the quantity.

[0029] Referring to the drawings of this application specification Figures 1 to 3As shown, a massage movement and massage arm according to the first preferred embodiment of the present application are explained in the following description. The massage movement includes a movement body and at least one massage arm arranged on the movement body, wherein the massage arm includes a massage arm bracket 10, at least one upper ball arm 20 and at least one lower ball arm 30 arranged on the massage arm bracket 10, wherein the upper ball arm 20 is fixed to one end of the massage arm bracket 10, and the lower ball arm 30 is movably arranged on the massage arm bracket 10, that is, the upper ball arm 20 and the lower ball arm 30 can move with the movement of the massage arm bracket 10 to realize the kneading, tapping and other actions of the massage arm. The upper ball arm 20 is fixed to one end of the massage arm bracket 10, so when the massage arm bracket 10 moves toward a specific direction, the upper ball arm 20 moves with the movement of the massage arm bracket 10. The lower ball arm 30 is movably arranged on the massage arm bracket 10, that is, when the lower ball arm 30 receives external force, the lower ball arm 30 can move or rotate relative to the massage arm bracket 10 to adjust the massage angle and strength. For example, the lower ball arm 30 can rotate up and down to fit the human body curve to achieve an adaptive effect.

[0030] It is worth mentioning that the present invention relates to a new type of 3D massage movement, which is intended to be applied to various types of massage equipment, such as massage chairs, massage sofas, etc., to provide users with a better and more comfortable massage experience. The entire 3D massage movement includes multiple key components, among which the massage arm is the part that directly contacts the user's body and performs massage actions, and its structural design plays a core role in realizing the advantages of the present invention.

[0031] The massage arms are arranged in pairs at corresponding positions of the movement, and each massage arm adopts the unique upper and lower ball arm separate structure design of the present invention. These massage arms cooperate with the driving mechanism and transmission components inside the movement through a reasonable connection method to ensure that they can receive the driving force from the power source of the movement, so as to accurately perform various massage actions, including but not limited to kneading, tapping and 3D ejection and other functional actions.

[0032] In detail, the upper ball arm 20 extends upward from the end of the massage arm bracket 10, and the lower ball arm 30 extends downward from the end of the massage arm bracket 10, and there is an adjustable angle between the upper ball arm 20 and the lower ball arm 30, and the external force drives the lower ball arm 30 to adjust the angle between the upper ball arm 20 and the lower ball arm 30 and the distance between the massage balls.

[0033] It is understandable that the upper ball arm is fixed at a specific position of the massage arm and is connected to the massage arm bracket through a high-strength and stable connecting component (such as a special fixing bolt or a chimeric structure, etc.). This fixing method can ensure that the upper ball arm always maintains a predetermined position and angle during the massage process, especially during the 3D ejection action, providing a stable and reliable force for the massage. For example, the material of the upper ball arm can be selected from medical silicone with suitable hardness and elasticity, and its surface is finely polished to ensure that it can provide effective massage force and comfortable touch when in contact with the human body.

[0034] The massage arm bracket connected to the upper ball arm is made of high-quality engineering plastics or lightweight metal alloys, which has sufficient strength to withstand various forces during the massage process, while ensuring that the overall weight of the movement is reasonable to achieve efficient force transmission. In terms of internal structure, the massage arm bracket is designed with a connection interface that matches the movement transmission structure, so as to accurately receive the power transmitted from the transmission components and drive the upper ball arm to perform corresponding massage actions.

[0035] The lower ball arm is connected to the massage arm bracket by a movable connection structure (screws or rivets), and the movable connection structure allows the lower ball arm to rotate up and down relative to the massage arm bracket. Specifically, the movable connection structure can adopt a design similar to a combination of a hinge joint and an elastic buffer element. For example, a small hinge with a certain degree of rotational freedom is set at the connection point, and an elastic buffer element such as an elastic rubber ring or a small spring is arranged around the hinge.

[0036] When the massage movement performs the 3D ejection function, as the entire massage arm is pushed outward, the lower ball arm will adapt to the curve of the human body and rotate up and down. When it comes into contact with different parts of the human body, such as the sides of the spine on the back of the human body, the shoulder curve and other uneven areas, the lower ball arm will automatically adjust its angle and position according to the actual human body contour shape, relying on the rotational freedom of the movable connection structure and the elastic deformation of the elastic buffer element. In this way, the lower ball arm can contact the human body in a soft and fitting manner, avoiding the problem of local body feeling too hard due to rigid ejection like traditional double-ball fixed massage arms, effectively improving the user's comfort.

[0037] like Figure 2 As shown, the massage arm bracket 10 includes a first bracket unit 11 and a second bracket unit 12, wherein the first bracket unit 11 and the second bracket unit 12 are arranged opposite to each other, and the first bracket unit 11 is fixedly connected to the second bracket unit 12. The massage arm bracket 10 has a proximal end portion and a distal end portion extending outward from the proximal end portion, wherein the upper ball arm 20 and the lower ball arm 30 are arranged at the proximal end portion of the massage arm bracket 10.

[0038] In this preferred embodiment of the present application, the upper ball arm 20 is fixedly arranged on the outside of the first bracket unit 11 or the second bracket unit 12. As an example, in this preferred implementation of the present application, the upper ball arm 20 is fixed on the outside of the first bracket unit 11. A movable mounting groove is provided between the first bracket unit 11 and the second bracket unit 12, and the lower ball arm 30 is pivotally arranged in the movable mounting groove between the first bracket unit 11 and the second bracket unit 12, and the lower ball arm 30 can rotate in the movable mounting groove when receiving an external force.

[0039] The massage arm further includes a reset mechanism 40, wherein the reset mechanism 40 is disposed on the massage arm bracket 10 and connected to the lower ball arm 30, the reset mechanism 40 provides a pre-tightening force for the lower ball arm 30, and when the lower ball arm 30 is rotated to a specific position by an external force, the reset mechanism 40 can drive the lower ball arm 30 to return to an initial position.

[0040] The reset mechanism 40 is implemented as an elastic element such as a torsion spring, a spring, a tension spring, and a rubber band.

[0041] It is worth mentioning that when the massage arm is subjected to external force, it moves a certain angle in the mounting groove. After the external force disappears, it performs a reset action through a tension spring or a torsion spring or a hydraulic rod, or performs reciprocating motion through a connecting rod through a motor reduction box structure, thereby realizing the kneading action of simulating human hands.

[0042] Specifically, the reset mechanism 40 includes an elastic element 41, a first reset unit 42 and a second reset unit 43, wherein the first reset unit 42 is arranged on the first bracket unit 11 or the second bracket unit 12 of the massage arm bracket 10, the second reset unit 43 is arranged on the lower ball arm 30, and the elastic element 41 connects the first reset unit 42 and the second reset unit 43.

[0043] The upper ball arm 20 includes an upper support arm 21 and at least one upper massage ball 22 arranged on the upper support arm 21, wherein the upper massage ball 22 is arranged at the end of the upper support arm 21; the lower ball arm 30 includes a lower support arm 31 and at least one lower massage ball 32 arranged on the lower support arm 31, wherein the lower massage ball 32 is arranged at the end of the lower support arm 31.

[0044] The massage arm further includes at least one limiter 50, wherein the limiter 50 is disposed on the massage arm support 10 and corresponds to the lower arm 31 of the lower ball arm 30, and is used to limit the movement stroke of the lower ball arm 30. Preferably, in this preferred embodiment of the present application, the limiter 50 is implemented as an elastic rubber element, which can reduce the noise generated by the collision of the lower ball arm 30.

[0045] The massage movement works as follows: when the massage movement is in the initial state where the 3D ejection function is not activated, the upper ball arm and the lower ball arm of the massage arm are in a naturally relaxed position, waiting to receive a power command from the movement drive mechanism. When the user chooses to start a massage program with a 3D ejection function, the drive motor inside the movement (e.g., a motor specifically used to control the 3D ejection action) starts to run, and the power is transmitted to the transmission branch where the massage arm is located through a series of transmission gears, worm gears and other transmission components (the design and selection of these transmission components are optimized according to the specific movement torque, speed and other parameter requirements).

[0046] As the power is transmitted, the massage arm begins to perform a 3D ejection action. Supported by a fixed structure, the upper ball arm moves steadily outward along the preset ejection direction. Its ejection force and displacement are precisely controlled by the drive motor speed, transmission ratio and related control parameters of the movement. At the same time, the lower ball arm, with its rotatable movable connection structure, begins to adaptively rotate according to the curve of the human body the moment it contacts the human body surface. For example, when the ejection action acts on an area where the back muscles of the human body are relatively thin, the lower ball arm will rotate slightly upward to reduce the ejection force perpendicular to the body surface, making it more in line with the physiological structure of the human body; and when encountering a part with thick muscles, the lower ball arm will rotate downward moderately according to the pressure feedback to ensure that it can fully contact and massage the deep muscle tissue, and maintain a comfortable massage feeling throughout the process.

[0047] In this process, the coordinated actions of the upper ball arm and the lower ball arm are not simply synchronized or independent, but through the overall structure of the massage arm and the exquisite coordination with the movement transmission system, a dynamic and balanced massage effect is achieved. The upper ball arm maintains a stable massage force output to meet the needs of deep stimulation of human acupuncture points and muscles, and the lower ball arm effectively compensates for the massage adaptability problems caused by differences in human body curves by adaptive rotation. The combined effect of the two greatly enhances the user experience in the 3D ejection massage process.

[0048] In kneading mode, the kneading drive mechanism of the movement (such as the transmission link composed of the kneading motor, kneading eccentric shaft, etc.) starts working, driving the massage arm to perform periodic swinging movements. At this time, the upper ball arm and the lower ball arm also work together. The upper ball arm provides basic pressure support for the kneading action at a fixed position and angle, and the lower ball arm flexibly rotates up and down with the swing of the massage arm and the contact with the human body, so that it can better fit the muscle contours of different parts of the human body during the kneading process. Whether it is in different massage areas such as the waist, shoulders or legs of the human body, a uniform and comfortable kneading effect can be achieved, as if simulating the flexible kneading movements of human hands, enhancing the overall massage comfort and effect.

[0049] When entering the tapping mode, the tapping drive component (such as a tapping motor that cooperates with the tapping eccentric shaft through a belt drive) drives the massage arm to produce rapid reciprocating motion to simulate the tapping action. In this process, the upper ball arm transmits rapid and rhythmic tapping force, and the lower ball arm uses its adaptive rotation mechanism to instantly adjust the angle according to the specific situation of the tapping part every time it touches the human body, avoiding the discomfort caused by harsh tapping to the user, making the tapping action more flexible and comfortable, effectively relaxing the muscles, and improving the user's experience in the tapping massage.

[0050] Through the functional performance of the massage arm in the above different massage modes, it can be seen that the upper and lower ball-arm separate arm structure of the present invention can play a unique advantage in a variety of massage function scenarios, significantly improving the problems existing in the massage arm design of the existing 3D massage movement, and providing users with a better, more comfortable and human-tailored massage experience.

[0051] It should be understood by those skilled in the art that the embodiments of the present invention described above and shown in the accompanying drawings are only examples and do not limit the present invention. The purpose of the present invention has been fully and effectively achieved. The functional and structural principles of the present invention have been demonstrated and explained in the embodiments, and the embodiments of the present invention may be deformed or modified in any way without departing from the principles.
