[0002] This disclosure claims priority to Chinese Patent Application No. 202520533609.9, filed on March 24, 2025, entitled “Reciprocating Massage Device”, the entire contents of which are incorporated herein by reference. Technical Field

[0003] This disclosure relates to the field of physiotherapy and massage technology, and in particular to a reciprocating massage device. Background Technology

[0004] Human body massagers, as a common health care device, are widely used in the home and personal care fields. With increasing health awareness and a greater pursuit of quality of life, the market offers a wide variety of massagers with diverse functions. Among them, massagers that utilize mechanical vibration as their primary working method have a large market share. These massagers generate periodic forces applied to specific parts of the body to promote blood circulation and relieve muscle tension and fatigue.

[0005] Traditional body massagers typically use an electric motor to drive an eccentric wheel or similar mechanism to achieve vibration, which in turn causes the skin and muscles of the massaged area to vibrate. The core of this massage method lies in adjusting the vibration amplitude and frequency parameters to alter the user's massage experience. Specifically, a smaller amplitude combined with a lower frequency often provides only mild stimulation, with limited effect on deep muscle relaxation; while increasing the amplitude and frequency can significantly enhance the massage sensation, allowing for deeper stimulation. However, in practical applications, it has been found that while excessively high vibration intensity can provide a strong massage sensation in a short time, it can also easily cause discomfort or even numbness in the massaged area, thus affecting the overall comfort and safety of the massage.

Detailed Implementation

[0039] The technical solutions of this disclosure will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this disclosure. Based on the embodiments of this disclosure, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this disclosure.

[0040] In the description of this disclosure, it should be noted that the terms "center," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," and "outer," etc., indicating orientation or positional relationships based on the orientation or positional relationships shown in the accompanying drawings, are only for the convenience of describing this disclosure and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this disclosure. Furthermore, the terms "first," "second," and "third" are only configured to describe differences in name and should not be construed as indicating or implying relative importance. Physical quantities in formulas, unless otherwise specified, should be understood as basic quantities in the International System of Units (SI), or derived quantities derived from basic quantities through mathematical operations such as multiplication, division, differentiation, or integration.

[0041] In the description of this disclosure, it should be noted that, unless otherwise expressly specified and limited, the terms "installation," "connection," and "linkage" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection between two components. Those skilled in the art can understand the specific meaning of the above terms in this disclosure based on the specific circumstances.

[0042] As shown in Figure 1, the reciprocating massage device provided in this embodiment includes: a housing 100, a drive member 200, an elastic frame 300, and a massage head 400; the drive member 200 and the elastic frame 300 are respectively installed on the housing 100, the drive member 200 is connected to the elastic frame 300 in a transmission manner, and causes the movable part 301 of the elastic frame 300 to reciprocate; the massage head 400 is connected to the movable part 301 in a transmission manner.

[0043] When a part of the body is subjected to mechanical vibration massage, the skin and muscles are driven to vibrate. If the vibration is concentrated, it can easily lead to excessive local vibration, resulting in numbness. Furthermore, without restraint, as the vibration intensity increases, the vibration direction and amplitude can easily change randomly, causing the vibration amplitude and direction of the massaged skin and muscles to become too chaotic, thus affecting massage comfort. In this embodiment, the movable part 301 has degrees of freedom to drive the massage head 400 to move back and forth, thereby forming a mechanical vibration massage. The increased range of motion of the massage head 400 results in a wider range of vibration sensation, preventing numbness caused by an overly concentrated vibration area. Additionally, the elastic frame 300 restrains the movable part 301, reducing the random changes in the vibration direction and amplitude, thus limiting excessive vibration of the massage head 400 and alleviating numbness and discomfort in the massaged area.

[0044] It is worth noting that the movable part 301 reciprocates under the driving action of the driving member 200. When it approaches the limit position of the movement stroke, the elastic force of the elastic frame 300 increases, which allows the movable part 301 to move in the reverse direction more smoothly, reducing the vibration of the housing 100 caused by the reciprocating motion of the movable part 301 and reducing the vibration feeling when holding the housing 100.

[0045] As shown in Figures 1, 2 and 5, in this embodiment of the present disclosure, the movable part 301 has a degree of freedom to reciprocate along the x-direction; the elastic frame 300 and the massage head 400 are arranged along the z-direction, wherein the x-direction is perpendicular to the z-direction.

[0046] During massage, the massage head 400 contacts the skin of the massaged area along the z-direction, and the movable part 301 drives the massage head 400 to achieve linear reciprocating motion along the x-direction. This avoids the massage head 400 making a hammering motion on the body along the z-direction during massage. The massage head 400 contacts and drives the massaged area to move linearly back and forth along the skin surface, thereby causing the skin and muscles to vibrate, achieving the effects of relaxing muscles and promoting blood circulation. This avoids the discomfort caused by disordered changes in the direction of vibration. The increased range of skin and muscle vibration can avoid the vibration sensation being concentrated in a small area, thus preventing numbness in the massaged area.

[0047] It should be noted that the movable part 301 can have the freedom to reciprocate in the x direction through the elastic structure of the elastic frame 300 itself. Alternatively, by setting a slide rail or slide groove extending in the x direction on the housing 100, the movable part 301 can reciprocate in the x direction by cooperating with the slide rail or slide groove.

[0048] As shown in Figures 1, 2, 4, 5 and 6, the movable part 301 is connected to the first elastic support part 302 at one end and to the second elastic support part 303 at the other end, wherein the x-direction points from the first elastic support part 302 to the second elastic support part 303; the first elastic support part 302 and the second elastic support part 303 are respectively connected to the housing 100.

[0049] In an optional embodiment, both the first elastic support portion 302 and the second elastic support portion 303 are configured as springs that elastically extend and retract along the x-direction. The first elastic support portion 302 and the second elastic support portion 303 jointly support the movable portion 301, thereby enabling the movable portion 301 to reciprocate along the x-direction.

[0050] In this embodiment, both the first elastic support portion 302 and the second elastic support portion 303 are configured as metal springs. The movable portion 301 is supported between the two metal springs. The two metal springs can extend along the z-direction and can reciprocate elastically tilting along the x-direction, thereby causing the movable portion 301 to reciprocate along the x-direction. Furthermore, when the movable portion 301 reciprocates along the x-direction to its travel limit position, the extension dimension of the two tilting metal springs in the z-direction decreases. This can be understood as the movable portion 301 moving towards the end of its travel and also slightly contracting along the z-direction. During massage, as the massage head 400 reciprocates, at the travel limit position, the pressure of the massage head 400 on the skin decreases as the movable portion 301 contracts along the z-direction, thereby reducing the pressure on the skin at the vibration limit position, reducing massage discomfort, and improving massage comfort.

[0051] Referring to Figures 1, 4, 5, 6, 7, and 8, the first elastic support portion 302 includes: a first longitudinal arm 321, a first curved portion 322, and a first spring arm 323. The first longitudinal arm 321 and the first spring arm 323 are spaced apart and extend along the z-direction, respectively. The top end of the first longitudinal arm 321 is connected to the movable portion 301, and the bottom end of the first longitudinal arm 321 is connected to the bottom end of the first spring arm 323 through the first curved portion 322. The second elastic support portion 303 includes: a second longitudinal arm 331, a second curved portion 332, and a second spring arm 333. The second longitudinal arm 331 and the second spring arm 333 are spaced apart and extend along the z-direction, respectively. The top end of the second longitudinal arm 331 is connected to the movable portion 301, and the bottom end of the second longitudinal arm 331 is connected to the bottom end of the second spring arm 333 through the second curved portion 332. The top ends of the first spring arm 323 and the second spring arm 333 are respectively connected to the housing 100.

[0052] The first spring arm 323 and the second spring arm 333 are respectively provided with hooks at their top ends, and the first spring arm 323 and the second spring arm 333 are respectively connected to the housing 100 through the hooks. The first longitudinal arm 321 and the first spring arm 323 are spaced apart to form an movable gap, and the second longitudinal arm 331 and the second spring arm 333 are spaced apart to form an movable gap. The first spring arm 323 and the second spring arm 333 elastically deform and tilt, thereby realizing the reciprocating movement of the movable part 301 in the x-direction.

[0053] Furthermore, the first elastic support portion 302 and the second elastic support portion 303 are respectively formed by bending a sheet-like structure; the thickness of the first spring arm 323 is smaller than the thickness of the first longitudinal arm 321, and the thickness of the second spring arm 333 is smaller than the thickness of the second longitudinal arm 331. By reducing the thickness of the first spring arm 323 and the second spring arm 333, the first spring arm 323 and the second spring arm 333 can be bent and deformed more easily, thereby reducing the elastic resistance that needs to be overcome to drive the movable part 301 to move. The driving member 200 drives the movable part 301 to move more smoothly and the transmission efficiency is higher.

[0054] Furthermore, the sheet-like structure mainly undergoes changes in bending degree during elastic deformation, making it less prone to torsional deformation. This ensures that the freedom of the movable part 301 is primarily manifested in reciprocating motion in the x-direction. The vibration massage effect generated by the massage head 400 driven by the movable part 301 is more orderly, resulting in higher massage comfort. It also prevents the movable part 301 from shifting during reciprocating motion, thereby preventing the movable part 301 from rubbing or bumping against the inner wall of the housing 100 due to tilting, reducing equipment operating noise, and extending the service life of the equipment.

[0055] In this embodiment, the movable part 301, the first elastic support part 302, and the second elastic support part 303 are configured as an integral structure. The movable part 301, the first elastic support part 302, and the second elastic support part 303 can be made of metal and formed into an integral structure by stamping or bending. Their structural performance can also be improved by heat treatment, resulting in better elasticity and flexibility, and they are easy to process and have lower production costs.

[0056] As shown in Figures 1, 2, 3, 4 and 5, the drive component 200 includes: a motor 210 and an eccentric wheel 220; the eccentric wheel 220 is connected to the motor 210 in a driving connection, and an eccentric shaft 221 is connected to the eccentric wheel 220. The axis of the eccentric shaft 221 is spaced apart from and parallel to the axis of the eccentric wheel 220; the eccentric shaft 221 is connected to the movable part 301 in a driving connection.

[0057] In this design, the axes of both the eccentric wheel 220 and the eccentric shaft 221 extend along the z-direction. The motor 210 drives the eccentric wheel 220 to rotate around its own axis, thereby causing the eccentric shaft 221 to rotate around the axis of the eccentric wheel 220. The movable part 301 can be connected to the eccentric shaft 221, thereby driving the movable part 301 to achieve periodic movement along a plane perpendicular to the eccentric shaft 221. The movable part 301 has a large stroke range, which makes the vibration range of the massage head 400 much larger than that of a conventional vibration motor, resulting in better shaking effect around the massaged area and higher massage comfort.

[0058] In an optional embodiment, the drive member 200 further includes a connecting rod 230, one end of which is hinged to the eccentric wheel 220 via an eccentric shaft 221, and the other end of which is hinged to the movable part 301.

[0059] When the eccentric wheel 220 drives the eccentric shaft 221 to rotate around the axis of the eccentric wheel 220, the eccentric shaft 221 drives the connecting rod 230. The connecting rod 230 is hinged to the movable part 301 through the shaft part 305 connected to the movable part 301, so that the movable part 301 can be pushed and pulled, thereby driving the movable part 301 to reciprocate along the x direction.

[0060] In addition, in other alternative embodiments, the drive unit 200 may also adopt an electromagnetic drive mechanism, which utilizes the magnetic force generated by the electromagnet and realizes the reciprocating change of the magnetic force, thereby directly driving the reciprocating motion of the magnet, and the magnet can drive the movable part 301 to reciprocate along the x direction.

[0061] As shown in Figures 1, 3, 4, 5 and 6, in another optional embodiment, the movable part 301 is connected to a damping member 500, and the eccentric wheel 220 is connected to the damping member 500 in a transmission connection to drive the movable part 301.

[0062] The eccentric wheel 220 can directly contact the damping element 500 via the eccentric shaft 221 to achieve transmission. Alternatively, the eccentric wheel 220 can be hinged to one end of a rod via the eccentric shaft 221, and the other end of the rod can be hinged to the damping element 500. Pushing and pulling the damping element 500 via the rod will drive the moving part 301 to reciprocate. The damping element 500 can reduce the mechanical impact of the transmission from the driving element 200 to the moving part 301, reduce vibration noise, and improve the quietness of the massager during operation.

[0063] In an optional embodiment, a groove 311 may be provided on the movable part 301, and the shock absorber 500 may be inserted into the groove 311.

[0064] The movable part 301 is machined into a groove 311 by stamping or cutting. The damping member 500 is embedded in the groove 311, thereby achieving a tight connection between the movable part 301 and the damping member 500, resulting in a compact structure. Furthermore, the movable part 301 is connected to a shaft 305. The damping member 500 has a hole that mates with the shaft 305. The damping member 500 is installed in the groove 311, and the shaft 305 is inserted into the hole on the damping member 500, making the connection between the damping member 500 and the movable part 301 more secure. Additionally, the damping member 500 can be interference-fitted into the groove 311, or it can be bonded to the movable part 301 and the shaft 305, thereby improving connection stability.

[0065] As shown in Figures 3, 5 and 6, in an optional embodiment, the damping member 500 is provided with a groove 501 extending in the y direction, and the eccentric shaft 221 extends in the z direction, wherein the x direction, y direction and z direction are perpendicular to each other; the eccentric shaft 221 is slidably fitted in the groove 501.

[0066] When the eccentric wheel 220 rotates, the eccentric shaft 221 can slide along the slide groove 501, thereby driving the damping member 500 to reciprocate in the x direction. The damping member 500 and the movable part 301 can reciprocate in the x direction synchronously.

[0067] It should be noted that when the elastic frame 300 is in its natural state, or when the elastic forces of the first elastic support 302 and the second elastic support 303 cancel each other out, the movable part 301 is positioned at the center of its stroke in the x-direction. At this time, the plane containing the axis of the eccentric shaft 221 and the axis of the eccentric wheel 220 is parallel to the yz plane. As the eccentric wheel 220 is driven to rotate, the eccentric shaft 221 drives the movable part 301 to reciprocate along the x-direction. As the movable part 301 moves away from the center of its stroke, the elastic resistance experienced by the movable part 301 gradually increases, and the speed in the x-direction gradually decreases. The direction change during the reciprocating motion is smoother, and the vibration and noise are lower.

[0068] Furthermore, as the movable part 301 drives the massage head 400, the massage head 400 contacts the skin and moves back and forth in the x direction. As the movable part 301 gradually decelerates and changes direction at both ends of its stroke in the x direction, the pulling effect of the massage head 400 on the skin at the extreme position of its stroke in the x direction is weakened, the skin and muscle vibrations are more relaxed, and the massage comfort is higher.

[0069] As shown in Figures 1 and 2, the drive unit 200 can be powered by a rechargeable battery installed inside the housing 100, or by a removable dry cell battery. To avoid the hassle of repeatedly changing batteries, a rechargeable battery is used, along with a power display screen or indicator light, making the massager more convenient to use.

[0070] As shown in Figures 1, 4 and 6, the movable part 301 is connected to the support part 304, which is inserted into the massage head 400. The movable part 301 can drive the support part 304 to reciprocate along the x-direction, thereby driving the massage head 400 to achieve reciprocating vibration massage.

[0071] In an optional embodiment, the support portion 304 can be a rigid support body, which can support the soft massage head 400, thereby preventing the massage head 400 from being excessively deformed due to its softness, and thus preventing the massage intensity from weakening due to excessive softness. This design retains the soft feel of the massage head 400 while ensuring it provides a stable and effective massage intensity during operation.

[0072] In another alternative embodiment, the support portion 304 can be made of soft rubber. This soft rubber support can drive the massage head 400 in reciprocating motion, and it can also undergo elastic deformation, thereby achieving flexible transmission. This not only reduces transmission impact but also improves massage comfort, making it suitable for users sensitive to massage intensity. Furthermore, with the massage head 400 made of a soft material, the soft massage head 400 fitted with the soft rubber support creates a nested structure that makes the overall structure even softer and more comfortable to the skin.

[0073] In an optional embodiment, the support part 304 can be detachably connected to the movable part 301 by means of threaded connection or snap-fit ​​connection, so that the support part 304 with different softness and hardness and elastic coefficient can be replaced.

[0074] As shown in Figures 1, 2, 4, 5, 7 and 8, the massage head 400 includes a soft rubber head 420, which is connected to the movable part 301. The soft rubber head 420 contacts the skin to improve massage comfort.

[0075] Furthermore, the massage head 400 also includes a mounting bracket 410, the soft rubber head 420 is connected to the mounting bracket 410, and the mounting bracket 410 is detachably connected to the housing 100.

[0076] Multiple massage heads 400 with different shapes and softness levels 420 can be configured, and users can change the massage head 400 according to their own preferences during massage.

[0077] It should be noted that the soft rubber head 420 is interference-fitted or sealed at the connection with the mounting bracket 410, and the mounting bracket 410 is then tightly connected to the housing 100. The housing 100 and the massage head 400 together can seal the drive component 200 and the elastic frame 300 inside.

[0078] Furthermore, the massage head 400 can also be made of a single piece of soft material, such as silicone, latex, or foam. These different materials may vary in feel and durability, thus providing different user experiences. Multiple independent small massage units can also be mounted on the mounting bracket 410, each made of a different soft material. This design allows users to obtain a richer massage experience.

[0079] In an alternative embodiment, a guide rail can also be installed on the housing 100, and the massage head 400 can be movably fitted to the guide rail, thereby allowing the massage head 400 to move more smoothly relative to the housing 100, which is suitable for obtaining a wider range of vibration massage effects.

[0080] In an optional embodiment, the housing 100 may be a multi-layer composite material housing, and a combination of various materials with different hardness or elasticity can be used to form the outer shell to achieve better protection. For example, a hard protective layer and a soft cushioning layer may be sequentially wrapped around the outer surface of the inner shell. A nano-coating may also be applied to the surface of the housing 100 to improve wear resistance and corrosion resistance while maintaining a good tactile feel.

[0082] In an optional embodiment, the inner shell 110 includes two half-shells that can be spliced ​​together to form an inner cavity between them. Alternatively, the two half-shells can be snap-fitted together or glued together, or the inner shell 110 can be fitted with a soft outer shell 120 to tightly wrap the two half-shells, ensuring a tight splice. Of course, the inner shell 110 can also be configured as a single-piece cavity structure with an opening communicating with the inner cavity. The drive unit 200, elastic frame 300, and battery, among other components, are installed within the inner cavity. The inner cavity of the inner shell 110 is sealed by covering the opening with a massage head 400.

[0083] In an optional embodiment, the soft outer shell 120 may be made of materials such as silicone, rubber, or latex, which can make the exterior of the shell 100 soft and improve the comfort of holding it in hand.

[0084] In addition, a cover 430 can be fitted over the soft rubber head 420 to protect it from corrosion or impact. The cover 430 can be used with the connecting mounting bracket 410 or the soft rubber shell 120, and the cover 430 can be securely installed by means of snap-fit ​​connection or interference fit.

[0085] As shown in Figures 1, 2, 5 and 9, the massage head 400 is connected to the inner shell 110, and a slot 600 is formed between the massage head 400 and the inner shell 110; one of the massage head 400 and the inner shell 110 is provided with a protrusion 401 that protrudes into the slot 600, and the other is provided with a limiting groove 111 that communicates with the slot 600 and is recessed away from the slot 600; the soft rubber shell 120 is provided with a protruding edge 121 that is inserted into the slot 600, the protruding edge 121 is provided with a groove 122 that matches the protruding part 401, and a limiting protrusion 123 that is inserted into the limiting groove 111.
