DETAILED DESCRIPTION

[0036] The technical solution of this utility model 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 utility model. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0038] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" 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 of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0039] like Figure 1 As shown, the reciprocating massage device provided in this embodiment of the present invention includes: a housing 100, a drive component 200, an elastic frame 300, and a massage head 400; the drive component 200 and the elastic frame 300 are respectively installed on the housing 100, the drive component 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.

[0040] When the human body part is subjected to mechanical vibration massage, the skin and muscles are driven to form tremor. If the vibration range is concentrated, it is easy to cause excessive local vibration feeling, thus numbness. In addition, when the mechanical vibration lacks constraint, as the vibration intensity increases, the vibration direction and vibration amplitude are easy to change in disorder, thus causing the skin and muscles of the massaged part to tremble in too disordered direction and amplitude, which will affect the massage comfort. In the embodiment, the movable part 301 has a degree of freedom to drive the massage head 400 to reciprocate, thus forming mechanical vibration massage. The movable range of the massage head 400 is increased, and the vibration feeling acting range of the massage is wider, thus avoiding numbness caused by too concentrated vibration feeling range. In addition, the elastic frame 300 can constrain the movable part 301, thus reducing the disordered change of the vibration direction and vibration amplitude of the movable part 301, thus limiting the excessive vibration of the massage head 400 and relieving the numbness of the massaged part.

[0041] It is worth noting that the movable part 301 reciprocates under the driving action of the driving part 200. When approaching the limit position of the movement stroke, the elastic force of the elastic frame 300 is increased, thus making the movable part 301 more smoothly reverse, reducing the vibration of the casing 100 caused by the reciprocating movement of the movable part 301, and reducing the vibration feeling when holding the casing 100.

[0042] As shown in Figure 1 , Figure 2 and Figure 5 , in the embodiment of the utility model, 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.

[0043] When massaging, the massage head 400 abuts against the skin of the massaged part along the z direction, the movable part 301 drives the massage head 400 to realize linear reciprocating motion along the x direction, avoiding the hammering action of the massage head 400 along the z direction on the human body during massage, and the massage head 400 contacts and drives the massaged part to move linearly along the skin surface, thus driving the skin and muscles to vibrate, achieving the effects of relaxing muscles and promoting blood circulation, avoiding the discomfort caused by disordered change of the vibration direction, and increasing the vibration range of the skin and muscles, thus avoiding the small concentrated range of vibration feeling, and avoiding numbness of the massaged part.

[0044] It is worth noting that the movable part 301 can have a degree of freedom to reciprocate along the x direction through the elastic structure of the elastic frame 300, and the movable part 301 can also reciprocate along the x direction by being matched with the slide rail or slide groove extending along the x direction arranged on the casing 100.

[0045] As shown in Figure 1 , Figure 2 ,Figure 4 , Figure 5 and Figure 6 As shown, one end of the movable part 301 is connected to the first elastic support part 302 and the other end is connected to the second elastic support part 303, 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.

[0046] 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.

[0047] 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.

[0048] See Figure 1 , Figure 4 , Figure 5 , Figure 6 , Figure 7 and Figure 8 The first elastic support portion 302 includes: a first longitudinal arm 321, a first bending 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 bending portion 322. The second elastic support portion 303 includes: a second longitudinal arm 331, a second bending 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 bending portion 332. The top ends of the first spring arm 323 and the second spring arm 333 are respectively connected to the housing 100.

[0049] The top ends of the first spring arm 323 and the second spring arm 333 are respectively provided with hook portions, and the first spring arm 323 and the second spring arm 333 are connected to the shell 100 through the hook portions. The first spring arm 323 and the second spring arm 333 are elastically deformed and inclined, so as to realize the reciprocating movement of the movable part 301 along the x direction.

[0050] Further, the first elastic support part 302 and the second elastic support part 303 are respectively formed by bending a sheet structure, the thickness dimension of the first spring arm 323 is smaller than the thickness dimension of the first longitudinal arm 321, and the thickness dimension of the second spring arm 333 is smaller than the thickness dimension of the second longitudinal arm 331. By reducing the thickness dimension 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 more easily bent and deformed, thereby reducing the elastic resistance to be overcome for driving the movable part 301 to move, and the driving part 200 drives the movable part 301 to move more smoothly and has higher transmission efficiency.

[0051] In addition, the sheet structure mainly changes in bending degree when elastically deformed, and is not easy to produce torsional deformation, thereby ensuring that the degree of freedom of the movable part 301 is mainly reflected in the reciprocating movement along the x direction, the vibration massage action direction generated by the driving of the massage head 400 by the movable part 301 is more orderly, the massage comfort is higher, and the movable part 301 can also be prevented from producing deviation in the reciprocating movement, thereby preventing the movable part 301 from rubbing or bumping against the inner wall of the shell 100 due to deviation, reducing the equipment operation noise, and prolonging the service life of the equipment.

[0052] In the embodiment, the movable part 301, the first elastic support part 302 and the second elastic support part 303 are configured as an integrated structure, and the movable part 301, the first elastic support part 302 and the second elastic support part 303 can be formed as an integrated structure by stamping or bending processing of a metal material, and the structure performance thereof can be improved by heat treatment, and the elasticity and flexibility are better, and the movable part 301, the first elastic support part 302 and the second elastic support part 303 are easy to process and have lower production cost.

[0053] As shown in FIGS. 1 to 3, the massage device 100 comprises a shell 100 and a driving part 200. Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 and Figure 5 As shown in FIGS. 1 to 3, the massage device 100 comprises a shell 100 and a driving part 200.

[0054] 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.

[0055] 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.

[0056] 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.

[0057] 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.

[0058] like Figure 1 , Figure 3 , Figure 4 , Figure 5 and Figure 6 As shown, in another optional embodiment, the movable part 301 is connected to the damping member 500, and the eccentric wheel 220 is connected to the damping member 500 to drive the movable part 301.

[0059] 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.

[0060] 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.

[0061] The active part 301 is formed with a groove 311 by punching or cutting, and the shock absorber 500 is embedded in the groove 311, so that the active part 301 is tightly connected with the shock absorber 500, and the structure is compact. In addition, the active part 301 is connected with the shaft part 305, the shock absorber 500 is provided with a hole position matched with the shaft part 305, the shock absorber 500 is installed in the groove 311, the shaft part 305 is inserted into the hole position on the shock absorber 500, and the shock absorber 500 is more stable in connection with the active part 301. In addition, the shock absorber 500 can be interference-fitted in the groove 311, or the shock absorber 500 can be bonded with the active part 301 and the shaft part 305, so as to improve the connection stability.

[0062] As shown in Figure 3 , Figure 5 and Figure 6 , in an optional embodiment, the shock absorber 500 is provided with a sliding groove 501 extending along the y direction, and the eccentric shaft 221 extends along the z direction, wherein the x direction, the y direction and the z direction are perpendicular to each other; the eccentric shaft 221 is slidingly matched in the sliding groove 501.

[0063] When the eccentric wheel 220 rotates, the eccentric shaft 221 can slide along the sliding groove 501, and in turn can drive the shock absorber 500 to reciprocate along the x direction, and the shock absorber 500 and the active part 301 can synchronously reciprocate along the x direction.

[0064] It should be noted that the elastic frame 300 is in a natural state, or the elastic forces of the first elastic support part 302 and the second elastic support part 303 cancel each other out, so that the active part 301 is in a stroke center position in the x direction, at this time, the axis of the eccentric shaft 221 is parallel to the yz plane. With the eccentric wheel 220 being driven to rotate, the eccentric shaft 221 drives the active part 301 to reciprocate along the x direction, and as the active part 301 moves away from the stroke center position, the elastic resistance of the active part 301 gradually increases, and the speed in the x direction gradually decreases, so that the direction transformation is more smooth during the reciprocating process, and the vibration noise is smaller.

[0065] In addition, the active part 301 drives the massage head 400 to contact the skin and reciprocate along the x direction, and as the active part 301 gradually slows down at both ends of the x direction stroke and reverses, the pulling effect of the massage head 400 on the skin at the extreme position of the x direction stroke is weakened, the skin and muscle tremors are more relaxed, and the massage comfort is higher.

[0066] As shown in Figure 1 and Figure 2As shown, the driving member 200 can be powered by a rechargeable battery installed in the casing 100, or by a detachable dry battery. To avoid the inconvenience of repeatedly replacing the battery, a rechargeable battery is used, and a power display screen or indicator light is provided, so that the massager is more convenient to use.

[0067] As shown in Figure 1 , Figure 4 and Figure 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, and the support part 304 can drive the massage head 400 to reciprocate and vibrate.

[0068] In an alternative embodiment, the support part 304 can be a hard support body that can be supported in the soft massage head 400, so as to avoid excessive deformation of the massage head 400 due to its softness, and thus avoid weakening the massage force due to excessive softness of the massage head 400. Through such design, the soft touch of the massage head 400 is retained, and stable and effective massage strength can be provided during operation.

[0069] In another alternative embodiment, the support part 304 can be a soft rubber support body that can drive the massage head 400 to reciprocate, and the soft rubber support body can be elastically deformed, thereby realizing flexible transmission, which not only reduces transmission impact, but also improves massage comfort, and is suitable for people who are sensitive to massage force. In addition, when the massage head 400 is made of soft material, the soft massage head 400 is sleeved with a soft rubber support body, and the two are nested to make the overall structure softer and the skin touch more comfortable.

[0070] In an alternative embodiment, the support part 304 can be detachably connected to the movable part 301 by screwing or snap connection, so that different support parts 304 with different degrees of softness and elastic coefficients can be replaced.

[0071] As shown in Figure 1 , Figure 2 , Figure 4 , Figure 5 , Figure 7 and Figure 8 , the massage head 400 includes a soft rubber head 420, which is in transmission connection with the movable part 301, and contacts the skin through the soft rubber head 420 to improve the massage comfort.

[0072] Further, the massage head 400 also includes a mounting bracket 410, and the soft rubber head 420 is connected to the mounting bracket 410, and the mounting bracket 410 is detachably connected to the casing 100.

[0073] The massage head 400 can be configured with different shapes, softness, and hardness of the soft rubber head 420, and the user can replace the massage head 400 according to personal preferences during massage.

[0074] It should be noted that the soft rubber head 420 is connected to the mounting frame 410 by interference fit or sealed bonding, and the mounting frame 410 is tightly connected to the casing 100. The drive member 200 and the elastic frame 300 are sealed inside through the casing 100 and the massage head 400.

[0075] In addition, the massage head 400 can also be made of soft materials such as silicone, latex, or foam. These different materials may differ in touch and durability, providing different user experiences. Multiple small massage units can also be installed on the mounting frame 410, each made of different soft materials. Such a design can provide users with a richer massage experience.

[0076] In an alternative embodiment, a guide rail can also be installed on the casing 100, and the massage head 400 is movably connected to the guide rail, so that the massage head 400 can move more smoothly relative to the casing 100, suitable for obtaining a larger range of vibration massage effect.

[0077] In an alternative embodiment, the casing 100 can be made of a multi-layer composite material shell. Different materials with different hardness or elasticity can be combined to form the shell to achieve better protection. For example, a hard protective layer and a soft buffer layer are wrapped outside the inner shell. A nano coating can also be applied to the surface of the casing 100 to improve wear resistance and corrosion resistance while maintaining good touch.

[0078] As shown in Figure 1 , Figure 2 and Figure 5 , the casing 100 includes an inner shell 110 and a soft rubber outer shell 120, and the drive member 200 and the elastic frame 300 are installed inside the inner shell 110, and the soft rubber outer shell 120 is sleeved outside the inner shell 110.
