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

[0032] See also Figure 2 The shell 10 can be used as a connecting base of the mechanical massager 1 for connecting various components. In the present embodiment, the shell 10 can be composed of two parts, that is, the shell 10 can include a first shell 140 and a second shell 150, wherein the first shell 140 can have a near-skin surface 110 close to the skin during massage and a far-skin surface 120 away from the skin.

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

[0034] See also Figure 3 The traction frame 30 is connected to the output shaft in driving connection so as to reciprocate linearly relative to the first shell 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 setting of the traction frame 30 will not increase the overall thickness of the mechanical massager 1, which is beneficial 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 members 40 are arranged symmetrically, so that the massage area of ​​the first massage members 40 can be more balanced. Each first massage member 40 can include a first massage portion 410 located at one end and a first connection portion 420 located at the other end, and each first massage member 40 is rotatably connected to the first housing 140 via a first rotating shaft 430. It can be understood that in this embodiment, the two first massage members 40 can be set to the same structure, which can facilitate the mold production of the first massage member 40, which is conducive to simplifying the production and assembly of the first massage member 40.

[0036] For further information, please refer again to Figure 3 The first massage part 410 can also be provided with a massage wheel 411, which can improve the comfort of the first massage part 410 when massaging the user. The embodiment of the present application does not limit the structure and number of the massage wheels 411. It can be understood that the number of massage wheels 411 should not be too many, which will increase the weight of the mechanical massager 1 and is not conducive to the carrying of the mechanical massager 1. For example, the massage wheels 411 can be set to 2 as shown in the figure.

[0037] For details, please also refer to Figure 3 , Figure 4 and Figure 5 The first massage part 410 may also be provided with an axle 412, and the massage wheel 411 may be movably provided on the axle 412, so that the first massage part 40 may generate rolling friction during the massage of the user, thereby improving the comfort of the user 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 member 40. The first connecting part 420 of each first massage member 40 is transmission-connected to the traction frame 30. The traction frame 30 reciprocates linearly to drive the two first massage members 40 to rotate around the first rotating shaft 430 respectively, so as to achieve the two first massage parts 410 approaching or moving away from each other. When the first massage member 40 contacts the part to be massaged by the user, the part to be massaged can achieve a massage effect.

[0039] Please continue reading Figure 3 , Figure 4 and Figure 5In one embodiment, the traction frame 30 and one of each of the first connecting parts 420 are provided with a first limiting column 421, and the other of the traction frame 30 and each of the first connecting parts 420 is provided with a first strip groove 330. The embodiment of the present application is described by taking the first limiting column 421 being provided on the first connecting part 420 and the first strip groove 330 being provided on the traction frame 30 as an example. Each first limiting column 421 is embedded in each of the first strip grooves 330 to slide relative to the first strip grooves 330 when the traction frame 30 reciprocates in a straight line, thereby driving the first massage member 40 to rotate around the first rotating shaft 430. The mechanical massager 1 provided in the embodiment of the present application has a simple connection structure. By embedding the first limiting column 421 in the first strip groove 330, the first massage member 40 can be driven to rotate around the first rotating shaft 430 when the traction frame 30 reciprocates in a straight line.

[0040] For further information, please refer to Figure 3 , Figure 4 and Figure 5 In one embodiment, one of the traction frame 30 and each of the first connecting parts 420 is provided with a guide post 422, and the other of the traction frame 30 and each of the first connecting parts 420 is provided with a guide slot 141. The present application embodiment is described by taking the guide post 422 being provided on the first connecting part 420 and the guide slot 141 being provided on the traction frame 30 as an example. The guide post 422 is embedded in the guide slot 141, so that the first connecting part 420 can ensure the accuracy of the motion trajectory of the first connecting part 420 in the relative motion with the traction frame 30.

[0041] In one embodiment, the two first massage members 40 may be cross-arranged and rotatably arranged on the first shell 140 at the intersection point via a first rotating shaft 430. That is, in this embodiment, only one first rotating shaft 430 may be arranged, and the two first massage members 40 may be connected to the first rotating shaft 430 at the same time. One first rotating shaft 430 may be used to simultaneously drive the two first massage members 40 to move. This may save one first rotating shaft 430, thereby reducing the overall volume of the mechanical massager 1, and at the same time reducing the number of components in the mechanical massager 1, thereby simplifying the assembly of the mechanical massager 1.

[0042] The mechanical massager 1 provided in the embodiment of the present application is provided with a traction frame 30, and uses the output shaft of the driving mechanism to drive the traction to reciprocate linear motion relative to the shell 10. At the same time, the traction frame 30 simultaneously drives the first rotating shafts 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 shafts 430 respectively, so as to achieve the two first massage parts 410 approaching or moving away from each other. At this time, the mechanical massager 1 is placed on the area of ​​the user's body to be massaged, so as to achieve massage of the user. The mechanical massager 1 provided in the embodiment of the present application does not need to set eccentric parts separately to drive the first massage parts 40, has a simple structure, a small number of parts, and is more conducive to production and assembly.

[0043] Please refer again Figure 1-Figure 3 In one embodiment, the mechanical massager 1 may further include: a second massage member 50. Similarly, two second massage members 50 may be provided, and the two second massage members 50 are arranged at intervals, so that the massage area of ​​the second massage member 50 may also be more uniform. Each second massage member 50 may include a second massage portion 510 located at one end and a second connection portion 520 located at the other end. Each second massage member 50 is rotatably connected to the housing 10 via a second rotating shaft 530. Specifically, each second massage member 50 is rotatably connected to the second housing 150 via a second rotating shaft 530. It can be understood that in this embodiment, the two second massage members 50 may be provided with the same structure, so that the mold production of the second massage member 50 can be facilitated, which is conducive to simplifying the production and assembly of the second massage member 50.

[0044] The second rotating shaft 530 is located between the second massage part 510 and the second connecting part 520 of each second massage member 50. The second connecting part 520 of each second massage member 50 is in transmission connection with the traction frame 30. The traction frame 30 reciprocates to drive the second massage members 50 to rotate around the second rotating shaft 530, so that the two second massage parts 510 are close to or away from the two first massage parts 410. When the second massage members 50 contact the user, the user's body can be massaged in a direction perpendicular to the massage direction of the first massage member 40. The above-mentioned arrangement of the second massage members 50 can drive the two first massage parts 410 to approach or move away from each other when the traction frame 30 reciprocates to drive the two first massage parts 410 to approach or move away from the two first massage parts 410, and at the same time drive the two second massage parts 510 to approach or move away from the two first massage parts 410, so as to achieve a richer massage effect.

[0045] Please also see Figure 1 and Figure 6In one embodiment, the mechanical massager 1 may further include a housing 70, which may be used to store components such as the housing 10, the driving mechanism, the traction frame 30, the first massage member 40, and the second massage member 50. Specifically, the first massage member 40 and the second massage member 50 may extend out of the housing 70 to perform a massage operation on the user. It should be noted that the embodiment of the present application does not limit the specific manner in which the first massage member 40 and the second massage member 50 extend out of the housing 70. For example, a notch 710 may be provided on the housing 70, and the first massage member 40 and the second massage member 50 may extend out of the housing 70 from the notch 710.

[0046] For further information, see Figure 2 and Figure 6 The second housing 150 may be disposed on the housing 70. For details, please refer to Figure 6 , a card block may be provided inside the housing 70, see Figure 2 , a card slot matching the card block may be provided on the second shell 150, and the shell 70 and the second shell 150 may be connected by the card block and the card slot, which may facilitate the assembly of the mechanical massager 1. It is understandable that the embodiment of the present application does not limit the specific connection method of the shell 70 and the second shell 150, for example, the positions of the card block and the card slot may be interchangeable, that is, in some other embodiments, the card block may also be provided on the second shell 150, and the card slot may also be provided inside the shell 70.

[0047] Please refer again Figure 2 and Figure 3 It is understandable that the two first massage members 40 and the two second massage members 50 can be respectively distributed on opposite sides of the traction frame 30. In this way, the traction frame 30 can be more evenly stressed as a whole during operation. At the same time, the two first massage members 40 and the two second massage members 50 are separated by the traction frame 30, and are not prone to collision and interference during operation, thereby ensuring that the first massage members 40 and the second massage members 50 can both work normally.

[0048] Please continue reading Figure 2 and Figure 3 Further, in one embodiment, the traction frame 30 and one of each second connection part 520 are provided with a second limiting column 521, and the other of the traction frame 30 and each second connection part 520 is provided with a second strip groove 310. Specifically, the embodiment of the present application takes the example of the second limiting column 521 being provided on the second connection part 520 and the second strip groove being provided on the traction frame 30 as an example.

[0049] Each second limiting column 521 is embedded in each second strip groove 310, so as to slide relative to the second strip groove 310 when the traction frame 30 reciprocates linearly, thereby driving the second massage member 50 to rotate around the second rotation axis 530. The connection structure between the traction frame 30 and the second limiting column 521 is simple. By embedding the second limiting column 521 in the second strip groove 310, each second massage member 50 can be driven to rotate around the second rotation axis 530 when the traction frame 30 reciprocates linearly. It can be understood that in another embodiment, the second limiting column 521 can also be set on the traction frame 30, and the second strip groove 310 can also be set on the second connecting portion 520, which is not limited here.

[0050] Please continue reading Figure 2 and Figure 3 Furthermore, in one embodiment, the mechanical massager 1 may further include an eccentric wheel 60, which may be connected to the output shaft and rotate under the drive of the output shaft, and the eccentric wheel 60 may be connected to the 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 structure of the mechanical massager 1 is simple, 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 see 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 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 described by taking the eccentric shaft 610 being provided on the eccentric wheel 60 and the clearance groove 320 being provided on the traction frame 30 as an example. The eccentric shaft 610 is embedded in the clearance groove 320 so as to slide 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 structure of the mechanical massager 1 is simple. 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 realizing the conversion of the eccentric motion of the eccentric wheel 60 into the reciprocating linear motion of the traction frame 30. It can be understood that in other embodiments, the eccentric shaft 610 can also be provided on the traction frame 30, and the clearance groove 320 can also be provided on the eccentric wheel 60, which is not limited here.

[0052] Please also see Figure 3 and Fig. 9In one embodiment, one of the traction frame 30 and the shell 10 is provided with a third limiting column 340, and the other of the traction frame 30 and the shell 10 is provided with a third strip groove 130. This embodiment is described by taking the third limiting column 340 being provided on the shell 10, specifically, being provided on the first shell 140 as an example, and the traction frame 30 being provided on the third strip groove 130 as an example. The third limiting column 340 is embedded in the third strip groove 130 and slidably cooperates with 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 shell 10, the third limiting column 340 is always limited in the third strip groove 130, thereby limiting the motion trajectory of the traction frame 30, so that the traction frame 30 can only reciprocate linearly, thereby ensuring the stability of the motion of the traction frame 30. It is understandable that, in other embodiments, the third limiting column 340 may also be disposed on the traction frame 30 , and the third strip groove 130 may also be disposed on the housing 10 , which is not limited here.

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

[0054] It can be understood that, in this embodiment, the first limiting column 421 can be integrally formed with the first connecting portion 420, the second limiting column 521 can be integrally formed with the second connecting portion 520, the third limiting column 340 can be integrally formed with the shell 10, and the eccentric shaft 610 can be integrally formed with the eccentric wheel 60, which can further simplify the assembly of the mechanical massager 1 and improve the convenience of user use.

[0055] In addition, in some embodiments, a sensing switch for sensing the movement position of the traction frame 30 or at least any one of the first massage components 40 may be further provided on the shell 10. The sensing switch may be used to sense the movement position of the traction frame 30 or the first massage component 40, so that when the mechanical massager 1 is turned off, the first massage component 40 stops at the same position each time, 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 the embodiment of the present application is as follows: first, the output shaft rotates under the drive of the servo motor disposed in the housing 70, and then the eccentric wheel 60 connected to the output shaft can be driven to rotate. Since the eccentric wheel 60 is provided with an eccentric shaft 610 eccentrically arranged relative to the center of the eccentric wheel 60, and the eccentric shaft 610 is embedded in the first clearance groove 320 of the traction frame 30, and since the clearance groove 320 is arranged along the X-axis direction, the eccentric shaft 610 can slide in the first clearance 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 driven by the eccentric shaft 610. The first massage member 40 is fixed to the first shell 140 by the first rotating shaft 430. At this time, the two ends of the first massage member 40 can perform a single pendulum motion with the first rotating shaft 430 as the center. Since the first limiting column 421 arranged on the first connecting portion 420 is connected to the traction frame 30 and embedded in the first strip groove 330 of the traction frame 30, the traction frame 30 can make the first limiting column 421 slide in the first strip groove 330 during the movement. Therefore, the first limiting column 421 can move under the drive of the traction frame 30, and then the first massage part 410 arranged at the other end of the first massage member 40 can also perform a single pendulum motion accordingly. Similarly, at this time, the second massage part 510 of the second massage member 50 can reciprocate in the direction close to or 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 to be massaged by the user, and a massage operation can be performed on the user.

[0057] The mechanical massager 1 provided in the embodiment of the present application is provided with a traction frame 30, and uses the output shaft of the driving mechanism to drive the traction to reciprocate linear motion relative to the shell 10. At the same time, the traction frame 30 simultaneously drives the first rotating shafts 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 shafts 430 respectively, so as to achieve the two first massage parts 410 approaching or moving away from each other. At this time, the mechanical massager 1 is placed on the area to be massaged on the user's body to achieve massage of the user. The mechanical massager 1 provided in the embodiment of the present application does not need to separately set eccentric parts to drive each first massage part 40, has a simple structure, a small number of parts, and is more conducive to production and assembly.

[0058] The above is part of the implementation methods of the present application. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principles of the present application. These improvements and modifications are also considered to be within the scope of protection of the present application.
