Description

Technical Field

[0001] This application relates to the field of massage instrument technology, and more particularly to a mechanical massager. Background Technology

[0002] With the development of technology, people often experience discomfort in their muscles or bones due to maintaining improper postures for extended periods during daily work, study, or leisure activities. In severe cases, this can even lead to illness, thus affecting their normal lives. To alleviate this discomfort, various types of massage devices have emerged on the market.

[0003] Among related technologies, massagers have a relatively complex structure and use many parts, which makes both production and assembly quite inconvenient. Summary of the Invention

[0004] In a first aspect, embodiments of this application provide a mechanical massager, comprising: a housing, a drive mechanism, a traction frame, and two first massage elements. The drive mechanism is mounted on the housing and includes an output shaft. The traction frame is tractively connected to the output shaft to reciprocate linearly relative to the housing under the drive of the output shaft. The two first massage elements are symmetrically arranged, each first massage element including a first massage portion at one end and a first connecting portion at the other end. Each first massage element is rotatably connected to the housing via a first rotating shaft, the first rotating shaft being located between the first massage portion and the first connecting portion of each first massage element. The first connecting portion of each first massage element is tractively connected to the traction frame. The reciprocating linear motion of the traction frame drives the two first massage elements to rotate around the first rotating shaft, thereby moving the two first massage portions closer together or further apart.

[0005] In one embodiment, the housing has a proximal surface closer to the skin and a distal surface farther from the skin during massage, and the reciprocating linear motion range of the traction frame does not exceed the range between the proximal surface and the distal surface.

[0006] In one embodiment, two second massage members are further included, which are arranged at intervals. Each second massage member includes a second massage portion at one end and a second connecting portion at the other end. Each second massage member is rotatably connected to the housing via a second rotating shaft. The second rotating shaft is located between the second massage portion and the second connecting portion of each second massage member. The second connecting portion of each second massage member is drively connected to the traction frame. The traction frame reciprocates linearly, thereby driving each of the second massage members to rotate around the second rotating shaft, so as to make the two second massage portions move closer to or further away from the two first massage portions.

[0007] In one embodiment, one of the traction frame and each of the second connecting portions is provided with a second limiting post, and the other of the traction frame and each of the second connecting portions is provided with a second strip groove. Each of the second limiting posts is embedded in each of the second strip grooves to slide relative to the second strip grooves when the traction frame reciprocates in a linear motion, thereby driving the second massage member to rotate around the second rotating axis.

[0008] In one embodiment, the two first massage members and the two second massage members are respectively distributed on opposite sides of the traction frame.

[0009] In one embodiment, an eccentric wheel is further included, which is connected to the output shaft and rotates under the drive of the output shaft. The eccentric wheel is connected to the traction frame to convert the eccentric motion of the eccentric wheel into the reciprocating linear motion of the traction frame.

[0010] In one embodiment, one of the eccentric wheel and the traction frame is provided with an eccentric shaft spaced apart from the output shaft, and the other of the eccentric wheel and the traction frame is provided with a relief groove. The eccentric shaft is embedded in the relief groove so as to slide relative to the relief groove when the eccentric wheel rotates, thereby driving the traction frame to reciprocate linearly relative to the housing.

[0011] In one embodiment, one of the traction frame and each of the first connecting portions is provided with a first limiting post, and the other of the traction frame and each of the first connecting portions is provided with a first strip groove. Each of the first limiting posts is embedded in each of the first strip grooves to slide relative to the first strip grooves when the traction frame reciprocates in a linear motion, thereby driving the first massage member to rotate around the first rotating shaft.

[0012] In one embodiment, one of the traction frame and the housing is provided with a third limiting post, and the other of the traction frame and the housing is provided with a third strip groove. The third limiting post is embedded in the third strip groove and slides in cooperation with the third strip groove. The extension direction of the third strip groove is parallel to the reciprocating linear motion trajectory of the traction frame.

[0013] In one embodiment, the housing is provided with a sensor switch for sensing the movement position of the traction frame or at least one of the first massage elements.

[0014] The mechanical massager provided in this application embodiment uses a traction frame and the output shaft of the drive mechanism to drive the traction relative to the housing to reciprocate linearly. At the same time, the traction frame drives the first rotating shafts of two symmetrically arranged first massage parts to rotate, thereby driving the two first massage parts to rotate around their respective first rotating shafts, so as to bring the two first massage parts closer to or further apart. When the mechanical massager is placed on the area to be massaged on the user's body, a massage can be performed on the user. The mechanical massager provided in this application embodiment does not require separate eccentric parts to drive each first massage part, has a simple structure, fewer parts, and is more conducive to production and assembly.

[0031] Please also refer to Figures 1-3 , Figure 1 This is a schematic diagram of the structure of a mechanical massager 1 provided in one embodiment of this application. Figure 2 This is a partial structural diagram of a mechanical massager 1 provided in one embodiment of this application. Figure 3 for Figure 2 The front view. In this embodiment, the mechanical massager 1 may include: a housing 10, a drive mechanism (not shown), a traction frame 30, and two first massage elements 40.

[0032] Please see Figure 2 The housing 10 can serve as a connecting base for the mechanical massager 1, used to connect various components. In this embodiment, the housing 10 can be composed of two parts, namely, the housing 10 can include a first housing 140 and a second housing 150. The first housing 140 can have a proximal surface 110 close to the skin during massage and a distal surface 120 away from the skin.

[0033] The drive mechanism can be installed in the housing 10. Specifically, the drive mechanism can be installed in the first housing 140. The drive mechanism includes an output shaft (not shown). This application embodiment does not limit the specific structure of the drive mechanism. For example, the drive mechanism can be a servo motor, etc.

[0034] Please see Figure 3 The traction frame 30 is connected to the output shaft for transmission, so that it reciprocates linearly relative to the first housing 140 under the drive of the output shaft. In one embodiment, the reciprocating linear motion range of the traction frame 30 does not exceed the range between the near skin surface 110 and the far skin surface 120. The above-mentioned traction frame 30 will not increase the overall thickness of the mechanical massager 1, which is conducive to reducing the volume of the mechanical massager 1, so that the mechanical massager 1 can be made thinner and thus more convenient for users to wear.

[0035] Please continue reading. Figure 3 The two first massage elements 40 are symmetrically arranged, which allows for a more balanced massage area. Each first massage element 40 may include a first massage portion 410 at one end and a first connecting portion 420 at the other end. Each first massage element 40 is rotatably connected to the first housing 140 via a first rotating shaft 430. It is understood that in this embodiment, the two first massage elements 40 can be configured with identical structures, which facilitates mold production of the first massage elements 40 and simplifies their production and assembly.

[0036] For further details, please refer to the following: Figure 3 The first massage unit 410 may also be equipped with massage rollers 411, which can improve the comfort of the first massage unit 410 when massaging the user. This application embodiment does not limit the structure or number of massage rollers 411. It is understood that the number of massage rollers 411 should not be too many, as this will increase the weight of the mechanical massager 1 and make it difficult to carry. For example, the massage rollers 411 can be set to two as shown in the figure.

[0037] For details, please refer to the following: Figure 3 , Figure 4 and Figure 5 The first massage unit 410 can also be provided with a wheel shaft 412, and the massage wheel 411 can be movably disposed on the wheel shaft 412. This allows the first massage component 40 to generate rolling friction during the user's massage, thereby improving the user's comfort during the massage.

[0038] The first rotating shaft 430 can be located between the first massage part 410 and the first connecting part 420 of each first massage element 40. The first connecting part 420 of each first massage element 40 is connected to the traction frame 30. The traction frame 30 reciprocates linearly, thereby driving the two first massage elements 40 to rotate around the first rotating shaft 430, so as to realize that the two first massage parts 410 move closer or further away from each other. When the first massage element 40 contacts the part of the user to be massaged, it can achieve a massage effect on the part of the user to be massaged.

[0039] Please continue reading. Figure 3 , Figure 4 and Figure 5In one embodiment, one of the traction frame 30 and each of the first connecting portions 420 is provided with a first limiting post 421, and the other of the traction frame 30 and each of the first connecting portions 420 is provided with a first strip groove 330. This application embodiment uses the example of the first limiting post 421 being located in the first connecting portion 420 and the first strip groove 330 being located in the traction frame 30 for illustration. Each first limiting post 421 is embedded in each first strip groove 330 to slide relative to the first strip groove 330 during the reciprocating linear motion of the traction frame 30, thereby driving the first massage element 40 to rotate around the first rotating shaft 430. The mechanical massager 1 provided in this application embodiment has a simple connection structure; by embedding the first limiting post 421 into the first strip groove 330, the first massage element 40 can be driven to rotate around the first rotating shaft 430 during the reciprocating linear motion of the traction frame 30.

[0040] For further information, please refer to [link / reference]. Figure 3 , Figure 4 and Figure 5 In one embodiment, one of the traction frame 30 and each of the first connecting portions 420 is provided with a guide post 422, and the other of the traction frame 30 and each of the first connecting portions 420 is provided with a guide groove 141. This embodiment is illustrated by taking the example of the guide post 422 being located in the first connecting portion 420 and the guide groove 141 being located in the traction frame 30. The guide post 422 is embedded in the guide groove 141 to ensure the accuracy of the movement trajectory of the first connecting portion 420 during relative movement with the traction frame 30.

[0041] In one embodiment, two first massage elements 40 can be arranged crosswise and rotatably mounted on the first housing 140 at the intersection point via a first rotating shaft 430. That is, in this embodiment, only one first rotating shaft 430 can be provided to connect the two first massage elements 40 to the first rotating shaft 430 simultaneously, and use one first rotating shaft 430 to drive the movement of the two first massage elements 40 at the same time. This can save one first rotating shaft 430, reduce the overall volume of the mechanical massager 1, and reduce the number of parts in the mechanical massager 1, thereby simplifying the assembly of the mechanical massager 1.

[0042] The mechanical massager 1 provided in this application embodiment uses a traction frame 30 and the output shaft of the drive mechanism to drive the traction relative to the housing 10 to reciprocate linearly. At the same time, the traction frame 30 drives the first rotating shaft 430 of two symmetrically arranged first massage parts 40 to rotate, thereby driving the two first massage parts 40 to rotate around the first rotating shaft 430, so as to realize that the two first massage parts 410 are closer or further apart. At this time, the mechanical massager 1 is placed on the area of ​​the user's body to be massaged, and massage can be performed on the user. The mechanical massager 1 provided in this application embodiment does not need to set eccentric parts to drive each first massage part 40 separately. It has a simple structure, fewer parts, and is more conducive to production and assembly.

[0043] Please refer to it again. Figures 1-3 In one embodiment, the mechanical massager 1 may further include a second massage element 50. Similarly, two second massage elements 50 may be provided, arranged at intervals, which also makes the massage area of ​​the second massage element 50 more uniform. Each second massage element 50 may include a second massage portion 510 at one end and a second connecting portion 520 at the other end. Each second massage element 50 is rotatably connected to the housing 10 via a second rotating shaft 530. Specifically, each second massage element 50 is rotatably connected to the second housing 150 via a second rotating shaft 530. It is understood that in this embodiment, the two second massage elements 50 may be configured with the same structure, which facilitates the mold production of the second massage elements 50 and simplifies the production and assembly of the second massage elements 50.

[0044] The second rotating shaft 530 is located between the second massage portion 510 and the second connecting portion 520 of each second massage member 50. The second connecting portion 520 of each second massage member 50 is connected to the traction frame 30. The traction frame 30 reciprocates linearly, thereby driving each of the second massage members 50 to rotate around the second rotating shaft 530. This allows the two second massage portions 510 to move closer to or further away from the two first massage portions 410. When the second massage member 50 comes into contact with the user, it can perform a massage on the user's body in a direction perpendicular to the massage direction of the first massage member 40. The aforementioned arrangement of the second massage members 50 allows the traction frame 30 to drive the two first massage portions 410 closer to or further away from each other during its reciprocating linear motion, while simultaneously driving the two second massage portions 510 closer to or further away from the two first massage portions 410, thus achieving a richer massage effect.

[0045] Please also refer to Figure 1 and Figure 6In one embodiment, the mechanical massager 1 may further include a housing 70, which can be used to house components such as the housing 10, drive mechanism, traction frame 30, first massage element 40, and second massage element 50. Specifically, the first massage element 40 and the second massage element 50 can extend out of the housing 70 for massaging the user. It should be noted that the embodiments of this application do not limit the specific manner in which the first massage element 40 and the second massage element 50 extend out of the housing 70. For example, a notch 710 may be provided on the housing 70, and the first massage element 40 and the second massage element 50 may extend out of the housing 70 from the notch 710, etc.

[0046] For further details, please refer to Figure 2 and Figure 6 The second housing 150 can be disposed on the outer housing 70. For details, please refer to [link / reference]. Figure 6 The interior of the outer casing 70 can be fitted with a locking mechanism; please refer to [link / reference]. Figure 2 The second housing 150 can be provided with a slot that matches the locking block. The outer housing 70 and the second housing 150 can be engaged by the locking block and the slot, which facilitates the assembly of the mechanical massager 1. It is understood that the embodiments of this application do not limit the specific connection method of the outer housing 70 and the second housing 150. For example, the positions of the locking block and the slot can be interchanged. That is to say, in some other embodiments, the locking block can also be provided on the second housing 150, and the slot can also be provided inside the outer housing 70.

[0047] Please refer to it again. Figure 2 and Figure 3 It is understandable that the two first massage elements 40 and the two second massage elements 50 can be distributed on opposite sides of the traction frame 30. This allows the traction frame 30 to be subjected to more even force during operation. At the same time, the two first massage elements 40 and the two second massage elements 50 are separated by the traction frame 30, making it less likely for them to collide or interfere with each other during operation, thus ensuring that both the first massage elements 40 and the second massage elements 50 can work normally.

[0048] Please continue reading. Figure 2 and Figure 3 Furthermore, in one embodiment, one of the traction frame 30 and each of the second connecting portions 520 is provided with a second limiting post 521, and the other of the traction frame 30 and each of the second connecting portions 520 is provided with a second strip groove 310. Specifically, this application embodiment takes the second limiting post 521 being provided in the second connecting portion 520 as an example and the second strip groove being provided in the traction frame 30 as an example for explanation.

[0049] Each second limiting post 521 is embedded in each second strip groove 310 to slide relative to the second strip groove 310 during the reciprocating linear motion of the traction frame 30, thereby driving the second massage element 50 to rotate around the second rotating shaft 530. The connection structure of the traction frame 30 and the second limiting post 521 described above is simple. By embedding the second limiting post 521 into the second strip groove 310, each second massage element 50 can be driven to rotate around the second rotating shaft 530 during the reciprocating linear motion of the traction frame 30. It is understood that in another embodiment, the second limiting post 521 can also be provided on the traction frame 30, and the second strip groove 310 can also be provided on the second connecting part 520; there is no limitation here.

[0050] Please continue reading. Figure 2 and Figure 3 Furthermore, in one embodiment, the mechanical massager 1 may also include an eccentric wheel 60, which can be connected to an output shaft and rotate under the drive of the output shaft. The eccentric wheel 60 can also be connected to a traction frame 30 to convert the eccentric motion of the eccentric wheel 60 into the reciprocating linear motion of the traction frame 30. In this embodiment, the mechanical massager 1 has a simple structure, and the reciprocating linear motion of the traction frame 30 can be achieved through the eccentric motion of the eccentric wheel 60.

[0051] Please also refer to Figure 7 and Figure 8 Furthermore, one of the eccentric wheel 60 and the traction frame 30 is provided with an eccentric shaft 610 spaced apart from the output shaft, and the other of the eccentric wheel 60 and the traction frame 30 is provided with a clearance groove 320. This embodiment is illustrated by taking the example of the eccentric shaft 610 being provided on the eccentric wheel 60 and the clearance groove 320 being provided on the traction frame 30. The eccentric shaft 610 is embedded in the clearance groove 320 so that it slides relative to the clearance groove 320 when the eccentric wheel 60 rotates, thereby driving the traction frame 30 to reciprocate linearly relative to the housing 10. In this embodiment, the mechanical massager 1 has a simple structure. By embedding the eccentric shaft 610 in the clearance groove 320, the connection between the eccentric wheel 60 and the traction frame 30 can be realized, thereby converting the eccentric motion of the eccentric wheel 60 into the reciprocating linear motion of the traction frame 30. It is understood that in other embodiments, the eccentric shaft 610 may also be provided on the traction frame 30, and the clearance groove 320 may also be provided on the eccentric wheel 60; this is not a limitation.

[0052] Please also refer to Figure 3 and Figure 9In one embodiment, one of the traction frame 30 and the housing 10 is provided with a third limiting post 340, and the other of the traction frame 30 and the housing 10 is provided with a third strip groove 130. This embodiment uses the example of the third limiting post 340 being located in the housing 10, specifically in the first housing 140, and the traction frame 30 being located in the third strip groove 130. The third limiting post 340 is embedded in and slides within the third strip groove 130, and the extension direction of the third strip groove 130 is parallel to the reciprocating linear motion trajectory of the traction frame 30. In this embodiment, when the traction frame 30 reciprocates linearly relative to the housing 10, the third limiting post 340 is always confined within the third strip groove 130, thereby limiting the motion trajectory of the traction frame 30 and ensuring that the traction frame 30 can only undergo reciprocating linear motion, thus ensuring the stability of the traction frame 30's movement. It is understood that in other embodiments, the third limiting post 340 may also be provided on the traction frame 30, and the third strip groove 130 may also be provided on the housing 10, without limitation.

[0053] Furthermore, in some embodiments, the first limiting post 421, the second limiting post 521, the third limiting post 340, and the eccentric shaft 610 can all be provided with baffles 80. The baffles 80 can be used to limit the positions of the first limiting post 421, the second limiting post 521, the third limiting post 340, and the eccentric shaft 610, preventing the first limiting post 421 from disengaging from the first strip groove 330 during its movement, preventing the second limiting post 521 from disengaging from the second strip groove 310 during its movement, preventing the third limiting post 340 from disengaging from the third strip groove 130 during its movement, and preventing the eccentric shaft 610 from disengaging from the relief groove 320 during its movement. It should be noted that the embodiments of this application do not limit the specific structure and size of the baffle 80. For example, the baffle 80 can be annular, the baffle 80 can be sleeved on the eccentric shaft 610, and the outer diameter of the first baffle 80 can be slightly larger than the width of the first limiting groove. In this way, while playing a limiting role, the volume of the first baffle 80 can be reduced, which in turn helps to reduce the volume of the mechanical massager 1.

[0054] It is understood that in this embodiment, the first limiting post 421 can be integrally formed with the first connecting part 420, the second limiting post 521 can be integrally formed with the second connecting part 520, the third limiting post 340 can be integrally formed with the housing 10, and the eccentric shaft 610 can be integrally formed with the eccentric wheel 60. This can further simplify the assembly of the mechanical massager 1 and improve the convenience of use for users.

[0055] In addition, in some embodiments, the housing 10 may also be provided with a sensor switch for sensing the movement position of the traction frame 30 or at least any of the first massage elements 40. The sensor switch can be used to sense the movement position of the traction frame 30 or the first massage element 40, so that when the mechanical massager 1 is turned off, the first massage element 40 always stops at the same position, which makes it more convenient for the user to use or store the mechanical massager 1.

[0056] The working principle of the mechanical massager 1 provided in this application embodiment is as follows: First, the output shaft rotates under the drive of the servo motor set in the housing 70, which in turn drives the eccentric wheel 60 connected to the output shaft to rotate. Since the eccentric wheel 60 is provided with an eccentric shaft 610 that is eccentrically set relative to the center of the eccentric wheel 60, and the eccentric shaft 610 is embedded in the relief groove 320 of the traction frame 30, and since the relief groove 320 is set along the X-axis direction, the eccentric shaft 610 can slide in the first relief groove 320 when it moves in a circular motion. At this time, the traction frame 30 will not move along the X-direction. Since there is no space for the eccentric shaft 610 to slide in the Y-axis direction, the traction frame 30 moves along the Y-axis direction under the drive of the eccentric shaft 610. The first massage element 40 is fixed to the first housing 140 via the first rotating shaft 430. At this time, both ends of the first massage element 40 can perform a pendulum motion with the first rotating shaft 430 as the center. Since the first limiting post 421 provided in the first connecting part 420 is connected to the traction frame 30 and embedded in the first strip groove 330 of the traction frame 30, the first limiting post 421 can slide in the first strip groove 330 during the movement of the traction frame 30. Therefore, the first limiting post 421 can move under the drive of the traction frame 30, and the first massage part 410 provided at the other end of the first massage element 40 can also perform a pendulum motion. Similarly, at this time, the second massage part 510 of the second massage element 50 can reciprocate along the direction of approaching or moving away from the first massage part 410 under the drive of the traction frame 30. At this time, the mechanical massager 1 is placed on the part of the user to be massaged, and the user can be massaged.

[0057] The mechanical massager 1 provided in this application embodiment uses a traction frame 30 and the output shaft of the drive mechanism to drive the traction relative to the housing 10 to reciprocate linearly. At the same time, the traction frame 30 drives the first rotating shaft 430 of two symmetrically arranged first massage parts 40 to rotate, thereby driving the two first massage parts 40 to rotate around the first rotating shaft 430, so as to realize that the two first massage parts 410 are closer or further apart. At this time, the mechanical massager 1 is placed on the area to be massaged on the user's body to perform a massage. The mechanical massager 1 provided in this application embodiment does not need to set eccentric parts to drive each first massage part 40 separately. It has a simple structure, fewer parts, and is more conducive to production and assembly.

Claims

1. A mechanical massager, characterized in that, include: case; A drive mechanism, mounted on the housing, includes an output shaft; A traction frame is connected to the output shaft for reciprocating linear motion relative to the housing under the drive of the output shaft. An eccentric wheel is connected to the output shaft and rotates under the drive of the output shaft. The eccentric wheel is connected to the traction frame to convert the eccentric motion of the eccentric wheel into the reciprocating linear motion of the traction frame. One of the eccentric wheel and the traction frame is provided with an eccentric shaft spaced apart from the output shaft. The other of the eccentric wheel and the traction frame is provided with a clearance groove. The eccentric shaft is embedded in the clearance groove so that it slides relative to the clearance groove when the eccentric wheel rotates, thereby driving the traction frame to reciprocate linearly relative to the housing. Two first massage elements are symmetrically arranged. Each first massage element includes a first massage portion at one end and a first connecting portion at the other end. Each first massage element is rotatably connected to the housing via a first rotating shaft. The first rotating shaft is located between the first massage portion and the first connecting portion of each first massage element. The first connecting portion of each first massage element is connected to the traction frame. The traction frame reciprocates linearly, thereby driving the two first massage elements to rotate around the first rotating shaft, so as to make the two first massage portions move closer or further apart. Two second massage elements are arranged at intervals. Each second massage element includes a second massage portion at one end and a second connecting portion at the other end. Each second massage element is rotatably connected to the housing via a second rotating shaft. The second rotating shaft is located between the second massage portion and the second connecting portion of each second massage element. The second connecting portion of each second massage element is drivenly connected to the traction frame. The traction frame reciprocates linearly, thereby driving each of the second massage elements to rotate around the second rotating shaft, so as to make the second massage portion move closer to or further away from the first massage portion. One of the traction frame and each of the second connecting parts is provided with a second limiting post, and the other of the traction frame and each of the second connecting parts is provided with a second strip groove. Each of the second limiting posts is embedded in each of the second strip grooves so as to slide relative to the second strip grooves when the traction frame reciprocates in a linear motion, thereby driving the second massage member to rotate around the second rotating axis.

2. The mechanical massager as described in claim 1, characterized in that, The housing has a proximal surface close to the skin and a distal surface away from the skin during massage, and the reciprocating linear motion range of the traction frame does not exceed the range between the proximal surface and the distal surface.

3. The mechanical massager as described in claim 1, characterized in that, The two first massage elements and the two second massage elements are respectively distributed on opposite sides of the traction frame.

4. The mechanical massager as described in claim 1, characterized in that, One of the traction frame and each of the first connecting parts is provided with a first limiting post, and the other of the traction frame and each of the first connecting parts is provided with a first strip groove. Each of the first limiting posts is embedded in each of the first strip grooves so as to slide relative to the first strip grooves when the traction frame reciprocates in a linear motion, thereby driving the first massage member to rotate around the first rotating shaft.

5. The mechanical massager as described in claim 1, characterized in that, One of the traction frame and the housing is provided with a third limiting post, and the other of the traction frame and the housing is provided with a third strip groove. The third limiting post is embedded in the third strip groove and slides in cooperation with the third strip groove. The extension direction of the third strip groove is parallel to the reciprocating linear motion trajectory of the traction frame.

6. The mechanical massager as described in any one of claims 1 to 5, characterized in that, The housing is provided with a sensor switch for sensing the movement position of the traction frame or at least one of the first massage elements.
