Technical Field

[0001] This invention relates to the field of health massage equipment technology, and more particularly to a massager. Background Technology

[0002] With the increasingly fast pace of life, people are experiencing greater work pressure, often working overtime to complete tasks. After a stressful day, people feel exhausted and often use massage devices to relieve fatigue and maintain physical and mental health. However, existing massage devices offer limited massage methods and fail to provide optimal results. Summary of the Invention

[0003] In view of the above-mentioned deficiencies of the prior art, the present invention provides a massager that aims to solve the problem that the existing massagers have a single massage mode and cannot provide a better massage effect.

[0004] This invention provides a massager, including at least one linkage assembly, a transmission assembly connected to the at least one linkage assembly, and a drive assembly. The drive assembly drives the linkage assembly to extend and retract along the axial direction of the transmission assembly and to reciprocate along the radial direction of the transmission assembly via the transmission assembly.

[0005] In this invention, the driving component of the massager can drive the connecting rod assembly to extend and retract along the axial direction of the transmission component, and also to reciprocate along the radial direction of the transmission component. The transmission component can simultaneously perform massage through both extension / retraction and reciprocating motion. Thus, the massager can provide users with multiple massage modes and has a superior massage effect. Attached Figure Description

[0028] The realization, functional features and advantages of the object of the present invention will be further described in conjunction with the embodiments and with reference to the accompanying drawings Specific embodiments

[0029] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present invention

[0030] Refer Figure 1-21 , an embodiment of the present invention provides a massage device 100, which can be used to massage human body parts such as the back, head, shoulders, neck, hands, legs, waist, abdomen, and feet. Specifically, the massage device 100 can be a back massage device, a head massage device, a shoulder and neck massage device, a hand massage device, a waist massage pad, an abdominal massage device, a leg massage device, a foot massage device, a massage chair or a massage chair pad, etc. The above are only examples of the uses of the massage device 100 of the present invention and are not limitations. Users can use the massage device 100 according to their own needs and preferences

[0031] The massage device 100 includes at least one link assembly 10, a transmission assembly 20 connected to the link assembly 10, and a drive assembly 30. The drive assembly 30 drives at least one link assembly 10 to perform telescopic movement along the axial direction of the transmission assembly 20 (i.e., move in the directions of approaching and departing from the drive assembly 30) through the transmission assembly 20 for massage, and at the same time can also drive at least one link assembly 10 to perform reciprocating movement along the radial direction of the transmission assembly 20 (i.e., move in the directions of approaching and departing from the transmission assembly 20) for massage. In this way, the massage device 100 can provide users with various massage methods and has a better massage effect. In order to increase the aesthetics and use safety of the massage device 100, the massage device 100 may further include a protective member that wraps the link assembly 10, the transmission assembly 20, and the drive assembly 30, and the protective member can be cloth, silicone or rubber

[0032] The massager 100 may include a plurality of linkage assemblies 10. Each linkage assembly 10 includes a first link 11, a second link 12, a first rotating shaft 13, a second rotating shaft 14, and a third rotating shaft 15. The second link 12 of each linkage assembly 10 is rotatably connected to the first link 11 via the second rotating shaft 14.

[0033] The two ends of the first connecting rod 11 are roughly cylindrical, and the width of the two ends can be greater than the width of the middle area, so that through holes 111 can be opened at both ends of the first connecting rod 11. The first rotating shaft 13 can be accommodated in the through hole 111 opened at the free end of the first connecting rod 11. The first connecting rod 11 and the first rotating shaft 13 are rotatably connected.

[0034] The second connecting rod 12 includes two opposing first connecting arms 121 and second connecting arms 122. The two ends of the second connecting arms 122 are approximately connected to the middle region of the two opposing first connecting arms 121, forming two opposing receiving portions 1211. Each first connecting arm 121 has through holes 1212 at both ends, which communicate with the corresponding receiving portion 1211. The end of the first connecting rod 11 furthest from the first rotating shaft 13 can be received in one of the receiving portions 1211. The second rotating shaft 14 can be received in the corresponding receiving portion 1211 and passes through the corresponding through holes 1212 and 111, allowing the first connecting rod 11 and the second connecting rod 12 to be rotatably connected. The third rotating shaft 15 can be received in the corresponding receiving portion 1211 and passes through the corresponding through hole 1212.

[0035] The first link 11 and the second link 12 are located outside the transmission assembly 20, and can massage the user during telescopic and reciprocating movements. Specifically, the connection part 123 of the first link 11 and the second link 12 is located on the outermost side, and can massage the user. When the link assembly 10 telescopically moves, the outermost connection part 123 can also telescopically move, performing a vertical pressing massage; when the link assembly 10 reciprocates, since the first link 11 and the second link 12 are rotatably connected, the outermost connection part 123 can continuously move in the direction close to and away from the transmission assembly 20, performing squeezing, pinching, and retraction massage. In this way, the massager 100 can provide the user with a variety of massage modes, with better massage effects (including pressing, squeezing, pinching, and retraction massage effects).

[0036] The transmission assembly 20 includes a bracket 21, a rotating member 22 connected to the drive assembly 30, and several sliding members 23 mounted on the bracket 21. The outer surface of the rotating member 22 has several spirally or inclined guide grooves 221, with adjacent guide grooves 221 having different orientations. Each sliding member 23 has a fixing member 24, and adjacent sliding members 23 are respectively connected to the first connecting rod 11 and the second connecting rod 12. When the drive assembly 30 drives the rotating member 22 to rotate, the fixing member 24 of the sliding member 23 interacts with the groove wall of the guide groove 221, causing the sliding member 23 to drive the connecting rod assembly 10 to extend and retract along the axial direction of the transmission assembly 20. Because adjacent guide grooves 221 have different orientations, adjacent sliding members 23 move in opposite directions along the axial direction of the transmission assembly 20, causing the first connecting rod 11 and the second connecting rod 12 of the connecting rod assembly 10 to reciprocate along the radial direction of the transmission assembly 20 while simultaneously extending and retracting along the axial direction of the transmission assembly 20.

[0037] The bracket 21 includes a connecting portion 211 and a support portion 212 connected to the connecting portion 211. The connecting portion 211 is generally barrel-shaped, with a hollow protrusion 2111 protruding from the approximate central area of ​​its upper surface, at least one engaging member 2113 protruding from its outer wall, and at least one protrusion 2114 protruding from its inner wall. The protrusion 2111 has a through hole 2112 communicating with the receiving cavity 2110 of the connecting portion 211. The driving member 31 of the driving assembly 30 can be partially received in the receiving cavity 2110, and the output shaft 311 can pass through the through hole 2112 and connect to the rotating member 22 received in the support portion 212.

[0038] The support portion 212 is generally rod-shaped, and the sliding member 23 is movably sleeved on the support portion 212. The support portion 212 includes a side wall 2121, a top wall 2122, and a receiving cavity 2123 for accommodating the rotating member 22. The sliding member 23 is movably sleeved on the side wall 2121 of the support portion 2122. The side wall 2121 is provided on a protrusion 2111, and the through hole 2112 of the protrusion 2111 communicates with the receiving cavity 2123 of the support portion 2122, so that the output shaft 311 extends into the receiving cavity 2123 through the through hole 2112 and connects with the rotating member 22. The side wall 2121 has an opening 2124 along the axial direction that communicates with the receiving cavity 2123. The fixing member 24 of the sliding member 23 passes through the opening 2124 and is received in the guide groove 221 of the rotating member 22. The top wall 2122 has a receiving hole 2125, and the end 222 of the rotating member 22 can be accommodated in the receiving hole 2125 to prevent the rotating member 22 from shaking.

[0039] In one embodiment, the reference Figure 9The opening 2124 is a single opening formed along the axial direction of the bracket 21, which may penetrate at least one end of the side wall 2121, or may not penetrate the end of the side wall 2121. In one embodiment, the opening 2124 penetrates both ends of the side wall 2121, and may further penetrate the top wall 2122. All the fixing members 24 of the slider 23 pass through the opening 2124 and are received in the corresponding guide grooves 221.

[0040] In another embodiment, the reference Figure 12 Multiple openings 2124 are provided along the axial direction of the bracket 21, and every two adjacent openings 2124 are separated by a spacer 2128. The number of openings 2124 can be the same as the number of sliding members 23, with each sliding member 23 corresponding to one opening 2124. The fixing member 24 of each sliding member 23 passes through an opening 2124 and is accommodated in the corresponding guide groove 221.

[0041] The sidewall 2121 has a roughly hexagonal cross-section, and the inner wall of the through hole of the slider 23 also has a roughly hexagonal structure. The cross-sections of the support 212 and the inner wall of the through hole of the slider 23 can also be circular, square, trapezoidal, triangular, or irregular shapes. This invention does not limit the specific structure of the support and the slider. At least one groove 2126 can be formed axially on the surface of the sidewall 2121, corresponding to at least one axially oriented protrusion 2127. Preferably, two spaced-apart grooves 2126 are formed on the surface of the sidewall 2121, corresponding to one protrusion 2127. The width of the groove 2126 and the width of the protrusion 2127 can be approximately the same. The groove 2126 can penetrate both ends of the sidewall 2121 and further penetrate the top wall 2122. The groove 2126 on the surface of the sidewall 2121 reduces the contact area between the slider 23 and the sidewall 2121, reducing friction and sliding resistance while ensuring support force, thus improving the smoothness of sliding.

[0042] The rotating component 22 is generally cylindrical in shape, and its outer surface is provided with a plurality of inclined or spirally arranged guide grooves 221, preferably bidirectional closed inclined grooves or spiral grooves arranged along the axial direction of the rotating component 22. The plurality of guide grooves 221 includes at least one first guide groove 221a and at least one second guide groove 221b. The first guide groove 221a and the second guide groove 221b are generally annular. Both the first guide groove 221a and the second guide groove 221b can be symmetrically arranged along the axial direction of the rotating component 22. Preferably, the plurality of guide grooves 221 includes a plurality of first guide grooves 221a and a plurality of second guide grooves 221b, which are spaced apart from each other and alternately arranged along the axial direction of the rotating component 22. The present invention does not limit the number, size, or shape of the guide grooves 221.

[0043] It should be noted that the guide groove 221 is a groove with a high point and a low point arranged along the axial direction of the rotating member 22. When the sliding member 23 slides along the guide groove 221 under the action of the fixing member 24, the sliding member 23 moves back and forth along the high point and the low point of the guide groove. The high point and the low point of the first guide groove 221a and the second guide groove 221b are adjacent, that is, the low point of the first guide groove 221a is adjacent to the high point of the second guide groove 221b, and the high point of the first guide groove 221a is adjacent to the low point of the second guide groove 221b, so that the adjacent sliding members 23 move closer or further away from each other under the drive of the rotating member 22.

[0044] Specifically, the first guide groove 221a extends spirally or obliquely from a first position 2211a (which may be a low point) on the outer surface of the rotating member 22 in a direction away from the drive assembly 30 to a second position 2212a (which may be a high point) on the outer surface of the rotating member 22, and then extends spirally or obliquely from the second position 2212a (which may be a high point) in a direction close to the drive assembly 30 back to the first position 2211a (which may be a low point). The second guide groove 221b is spaced apart from the first guide groove 221a, and extends spirally or obliquely from a third position 2211b (which may be a low point) on the outer surface of the rotating member 22 in a direction away from the drive assembly 30 to a fourth position 2212b (which may be a high point) on the outer surface of the rotating member 22, and then extends spirally or obliquely from the fourth position 2212b (which may be a high point) in a direction close to the drive assembly 30 back to the third position 2211b (which may be a low point). The third position 2211b may be adjacent to or close to the second position 2212a. The angle between the line connecting the first position 2211a and the second position 2212a and the line connecting the third position 2211b and the fourth position 2212b can be 30-60°, such as 30°, 40°, 50° or 60°. This not only allows the linkage assembly 10 to have a longer running distance (running distance in the reciprocating direction and the telescopic direction), but also allows the massager to have a better massage effect (massage effects such as pressing, squeezing, pinching, and retraction).

[0045] When the drive assembly 30 drives the rotating member 22 to rotate, the fixing member 24 abuts against the groove walls of the first guide groove 221a and the second guide groove 221b respectively, interacts with the groove walls of the first guide groove 221a and the second guide groove 221b, and moves / slides between the aforementioned low point and high point. Since the fixing member 24 is fixed on the sliding member 23, the sliding member 23 can drive the fixing member 24 and the connecting rod assembly 10 to move / slide together between the aforementioned low point and high point. Since the first guide groove 221a and the second guide groove 221b are oriented in opposite directions, and the first connecting rod 11 and the second connecting rod 12 are rotatably connected, the first connecting rod 11 and the second connecting rod 12 of the connecting rod assembly 10 can continuously move in directions that approach and move away from each other, achieving massage effects such as squeezing, pinching, and contraction.

[0046] The plurality of sliding members 23 includes a first sliding member 23a (located at the upper end of the rotating member 22), a second sliding member 23b (located at the lower end of the rotating member 22), and at least one third sliding member 23c located between the first sliding member 23a and the second sliding member 23b. Preferably, the plurality of sliding members 23 includes a first sliding member 23a, a second sliding member 23b, and a plurality of third sliding members 23c. The present invention does not limit the number, size, or shape of the sliding members 23, as long as it is suitable for actual needs. The number of sliding members 23 can be three or more to increase the massage area. The distance between the sliding members 23 can be set to obtain different degrees of pinching (clamping).

[0047] The first sliding member 23a is located above the third sliding member 23c and includes a through hole 231a, a mounting portion 232a for mounting the fixing member 24, and at least one connecting portion 233a rotatably connected to the first connecting rod 11. The first sliding member 23a is movably sleeved on the bracket 21 through the through hole 231a. The cross-sectional shape of the inner wall 2311a of the through hole 231a matches the cross-sectional shape of the side wall 2121, and is approximately hexagonal. The inner wall 2311a of the through hole 231a can also be circular, square, trapezoidal, triangular, or irregular in shape, etc., and the present invention does not limit this. A locking block 2312a protrudes from the inner wall 2311a of the through hole 231a, and the locking block 2312a is slidably accommodated in the opening 2124 of the bracket 21.

[0048] The mounting part 232a and the locking block 2312a are respectively provided on the outer wall 2313a and inner wall 2311a of the through hole 231a. The mounting part 232a has a through hole 2321a, a mounting hole 2322a and a mounting groove 2323a. The through hole 2321a and the mounting hole 2322a are both provided on the bottom wall of the mounting groove 2323a and pass through the locking block 2312a.

[0049] The fastener 24 includes a mounting block 241 and a fixing part 242 mounted on the mounting block 241. The mounting block 241 and the fixing part 242 can be an integral structure for easy installation and disassembly, or they can be separate structures. The fixing part 242 can be spherical, and its material can be silicone, plastic, metal, or wood, etc. The present invention does not limit the shape and material of the fixing part 242. The shape of the mounting block 241 is adapted to the mounting groove 2323a and is installed in the mounting groove 2323a. The mounting block 241 includes a mounting part 2411 and a mounting hole 2412. The mounting part 2411 can be a groove or a protrusion with a groove. The width of the guide groove 221 is approximately the same as or slightly larger than the width of the fixing part 242. The fixing part 242 is rotatably accommodated in the mounting part 2411, and the fixing part 242 rolls in contact with the groove wall of the guide groove 221. Connectors (such as screws) can pass through mounting holes 2412 and 2322a to fix the mounting block 241 and mounting part 232a together. After the mounting block 241 is accommodated in the mounting groove 2323a, the mounting part 2411 is accommodated in the through hole 2321a, or partially extends out of the through hole 2321a, and the fixing part 242 can extend out of the through hole 2321a and be accommodated in the guide groove 221 of the rotating member 22. The fixing part 242 can also be elliptical, columnar, or block-shaped, etc., and is fixedly accommodated in the mounting part 2411. The fixing part 242 slides in contact with the groove wall of the guide groove 221. In this case, the fixing part 242 can be a pin, which is embedded in the guide groove 221 and slides in contact with the groove wall of the guide groove 221. Of course, the mounting part 2411 can also be omitted, and the fixing part 242 is directly integrally formed with the mounting block 241.

[0050] The connecting portion 233a includes two oppositely arranged connecting arms 2331a, correspondingly forming connecting grooves 2332a. The lower end 2333a of the connecting arm 2331a has a through hole 2334a.

The lower end 2333a of the connecting arm 2331a may be generally cylindrical to facilitate the forming of the through hole 2334a.

[0051] In this embodiment, the outer wall 2313a is approximately hexagonal in shape, and each face can be either straight or curved. Several spaced-apart connecting portions 233a can be provided on the outer wall 2313a, thus allowing for multiple spaced-apart connecting rod assemblies 10 to be arranged around the outer wall 2313a, increasing the massageable area and achieving a better massage effect. The outer wall 2313a can also be circular, square, trapezoidal, triangular, or irregular in shape, etc., and the present invention does not impose any limitations on this.

[0064] Figure 21In another embodiment, the rotating member 22 has at least one third guide groove 221c and at least one fourth guide groove 221d on its outer surface. These are unidirectional closed inclined grooves or spiral grooves, both of which can be symmetrically arranged along the axial direction. Preferably, multiple third guide grooves 221c and multiple fourth guide grooves 221d are provided, with each pair of third guide grooves 221c and fourth guide grooves 221d connected. The third guide groove 221c extends spirally or obliquely from the fifth position 2211c (which may be the midpoint) in a direction away from the drive assembly 30 to the sixth position 2212c (which may be the high point), and then extends spirally or obliquely from the sixth position 2212c in a direction close to the drive assembly 30 back to the fifth position 2211c (which may be the midpoint). The fourth guide groove 221d is connected to the third guide groove 221c at the fifth position 2211c. The fourth guide groove 221d extends spirally or obliquely from the fifth position 2211c (which may be the midpoint) in a direction close to the drive assembly 30 to the seventh position 2212d (which may be the low point), and then extends spirally or obliquely from the seventh position 2212d (which may be the low point) in a direction away from the drive assembly 30 back to the fifth position 2211c (which may be the midpoint). Adjacent sliding members 32 are respectively provided corresponding to the third guide groove 221c and the fourth guide groove 221d, and two adjacent fixing parts 242 can be respectively accommodated in the connected third guide groove 221c and the fourth guide groove 221d. When the rotating member 22 rotates, under the restriction of the sliding member 23, one fixed part 242 slides upward along the third guide groove 221c. When it reaches the high point, it changes direction and slides to the middle point. The sliding member 23 abuts against it, causing the fixed part 242 to slide upward again. The other fixed part 242 slides downward along the fourth guide groove 221d. When it reaches the low point, it changes direction and slides to the middle point. The sliding member 23 abuts against it, causing the fixed part 242 to slide downward again. This process is repeated continuously.
