[0033] The present utility model provides a massage device core component 100.

[0034] Please refer to Figures 1 to 6 In an embodiment of the present utility model, the massage device movement component 100 includes a frame 110, a gear set 120, a transmission member 130, and a rocker 140. The gear set 120 includes an output gear 121, and the output gear 121 is rotatably mounted on the frame 110. The transmission member 130 has a first connection portion 131 and a second connection portion 132. The output gear 121 has a mating portion 1211. The transmission member 130 is disposed between the rocker 140 and the output gear 121. The first connection portion 131 is connected to the mating portion 1211, and the second connection portion 132 is connected to one end of the rocker 140. The end of the rocker 140 away from the transmission member 130 is used to connect a massage head.

[0035] It can be understood that when the output gear 121 rotates, it can drive the transmission member 130 to rotate through the first connection portion 131 and the mating portion 1211, so that the second connection portion 132 of the transmission member 130 drives the rocker 140 to rotate, and transmits the power to the massage head at the end of the rocker 140. The scalp can be massaged by the rotation of the massage head. In a traditional driving structure, an inclined hole is usually formed in the output gear 121, and the end of the rocker 140 away from the massage head is obliquely inserted into the inclined hole of the output gear 121. The output gear 121 directly drives the massage head to rotate through the rocker 140. However, in this structure, the die structure of the output gear 121 is complex and inconvenient to process, and the inclined hole and the rocker 140 are arranged in cooperation, so that the force on the output gear 121 is uneven, resulting in jitter and noise. In this solution, a transmission member 130 is arranged between the rocker 140 and the output gear 121, which can effectively avoid the uneven force on the gear, and there is no need to form an inclined hole in the output gear 121, simplifying the die structure of the output gear 121, reducing the production difficulty and saving the mold opening cost.

[0036] In one embodiment, the second connection portion 132 is inclined, and the axis of the rocker 140 forms an angle with the axis of the output gear 121, so that the end of the rocker 140 away from the transmission member 130 makes a circular motion around the axis of the output gear 121.

[0037] Such as Figure 2 、 Figure 4 And Figure 5As shown, in an embodiment of the present utility model, the axis of the first connecting portion 131 on the transmission member 130 coincides with the central axis of the output gear 121, the second connecting portion 132 is inclined, and when the output gear 121 rotates, the second connecting portion 132 makes a circular motion around the axis of the output gear 121. One end of the rocker 140 away from the massage head is connected to the second connecting portion 132, so that an included angle is formed between the axis of the rocker 140 and the axis of the output gear 121. The second connecting portion 132 transmits power to the rocker 140, and the rocker 140 makes a circular swinging motion centered on the axis of the output gear 121, causing the massage head at the end of the rocker 140 to rotate.

[0038] It should be noted that by arranging the second connecting portion 132 on the transmission member 130 to be inclined, the swinging motion of the rocker 140 can be realized without opening an inclined hole on the output gear 121. Moreover, the axis of the transmission member 130 coincides with the axis of the output gear 121, and the transmission member 130 provides a buffer space between the rocker 140 and the output gear 121, making the force on the output gear 121 more uniform, effectively reducing jitter and noise, and improving the user experience.

[0039] In an embodiment, the massager movement assembly 100 further includes a pin 150. A first connecting groove 141 is formed at one end of the rocker 140 close to the transmission member 130, and a second connecting groove 1321 is formed on the second connecting portion 132. Two ends of the pin 150 are respectively inserted into the first connecting groove 141 and the second connecting groove 1321 to connect the transmission member 130 and the rocker 140.

[0040] As Figure 2 、 Figure 4 and Figure 6 As shown, in an embodiment of the present utility model, the rocker 140 is connected to the transmission member 130 through a pin 150. Specifically, a first connecting groove 141 is formed on the abutting surface of the rocker 140 facing the transmission member 130, and a second connecting groove 1321 is formed on the abutting surface of the second connecting portion 132 of the transmission member 130. Two ends of the pin 150 are respectively inserted into the first connecting groove 141 and the second connecting groove 1321, and the rocker 140 abuts against the second connecting portion 132. The pin 150 is hidden in the two connecting grooves. It can be understood that by arranging the pin 150, the disconnection between the second connecting portion 132 and the end of the rocker 140 during the massage process can be avoided, improving the stability of power transmission. Further, the pin 150 is also beneficial for the docking of the transmission member 130 and the rocker 140, reducing the installation difficulty and improving the production efficiency.

[0041] In one embodiment, the massager movement assembly 100 further includes a gland 160. The gland 160 is connected to the frame 110 and encloses to form an installation cavity 160a. The transmission member 130 is disposed in the installation cavity 160a. A through hole 161 is formed in the gland 160. One end of the rocker 140 passes through the through hole 161 and is connected to the second connecting portion 132.

[0042] As Figure 4 and Figure 6 shown, in one embodiment of the present utility model, the massager movement assembly 100 further includes a gland 160. Specifically, the gland 160 is disposed on the frame 110 and on one side of the transmission member 130 and the rocker 140. The gland 160 is connected to the frame 110 to form a hollow interior installation cavity 160a. The transmission member 130 is rotatably disposed in the installation cavity 160a. The first connecting portion 131 is disposed towards the frame 110 for connecting the output gear 121. The second connecting portion 132 is disposed towards the through hole 161 in the gland 160. The end of the rocker 140 away from the massage head passes through the through hole 161 and is connected to the second connecting portion 132. The diameter of the through hole 161 is larger than the diameter of the rocker 140, so that the rocker 140 can swing in a circular motion at the through hole 161. It should be noted that the gland 160 can be used to press the transmission member 130 and / or the rocker 140 to prevent the transmission member 130 from disengaging from the output gear 121, or the transmission member 130 from disengaging from the rocker 140, so as to improve the structural stability of the massager movement assembly 100.

[0043] In one embodiment, a spherical portion 142 is provided at one end of the rocker 140 close to the transmission member 130. The spherical portion 142 is located between the transmission member 130 and the gland 160. The edge of the gland 160 at the through hole 161 is in sliding contact with the outer surface of the spherical portion 142.

[0044] As Figure 4 and Figure 6As shown, in order to reduce the friction between the rocker 140 and the gland 160, in an embodiment of the present utility model, a hemispherical spherical portion 142 is provided at one end of the rocker 140 close to the transmission member 130. Specifically, the spherical portion 142 is located between the gland 160 and the transmission member 130, and the outer surface of the spherical portion 142 is in sliding contact with the edge of the through hole 161 of the gland 160. When the output gear 121 rotates, the transmission member 130 drives the rocker 140 to swing circumferentially around the axis of the output gear 121. The outer surface of the spherical portion 142 is in sliding contact with the edge of the gland 160 at the through hole 161, so that the gland 160 presses the rocker 140 and the transmission member 130, while reducing the frictional force between the rocker 140 and the gland 160, making the rocker 140 swing more smoothly, reducing the wear between components, and being beneficial to improving the service life of the product. It can be understood that the spherical portion 142 being hemispherical can save the internal space of the movement assembly, thereby reducing the overall volume of the massager. Of course, the spherical portion 142 can also be set as a spherical shape, which is not specifically limited herein.

[0045] In an embodiment, a limiting post 1421 is provided on the spherical portion 142, and a limiting groove 162 corresponding to the limiting post 1421 is provided in the gland 160. The limiting post 1421 is in movable contact with the groove wall of the limiting groove 162 to limit the movement range of the rocker 140.

[0046] As Figure 6 As shown, in an embodiment of the present utility model, two limiting posts 1421 are symmetrically arranged at the edge of the spherical portion 142, and the axes of the two limiting posts 1421 coincide. Two limiting grooves 162 communicating with the installation cavity 160a are provided in the gland 160, and the two limiting grooves 162 are respectively arranged corresponding to the two limiting posts 1421. When the output gear 121, the transmission member 130, the rocker 140, and the gland 160 are installed on the frame 110, the two limiting posts 1421 are respectively located in the two limiting grooves 162 and are in contact with the groove walls of the limiting grooves 162. During the circumferential swinging process of the rocker 140, the limiting posts 1421 rotate in the limiting grooves 162 and move up and down along the depth direction of the limiting grooves 162, so as to prevent the swinging amplitude from being too large or the rocker 140 from shifting while the rocker 140 completes the swinging action, ensuring the smoothness of the massage process and improving the massage comfort of the user.

[0047] In an embodiment, the massager movement assembly 100 further includes a motor 170 and a worm 180. The gear set 120 further includes a first-stage double-connected gear 122, a second-stage double-connected gear 123, and an intermediate gear 124. The motor 170 is installed on the frame 110 and is connected to the worm 180. The first-stage double-connected gear 122 connects the worm 180 and the second-stage double-connected gear 123, the intermediate gear 124 connects the second-stage double-connected gear 123, and the second-stage double-connected gear 123 and the intermediate gear 124 are respectively connected to an output gear 121.

[0048] As Figure 1 and Figure 3 shown, in an embodiment of the present utility model, the massager movement assembly 100 further includes a motor 170 and a worm 180. The gear set 120 further includes a first-stage double gear 122, a second-stage double gear 123, and an intermediate gear 124. The motor 170 is mounted on the frame 110 and its output end is connected to the worm 180. Four output gears 121 are respectively arranged at the four corners of the frame 110. Two first-stage double gears 122 are respectively connected to both sides of the worm 180. Each first-stage double gear 122 is connected to a second-stage double gear 123. The second-stage double gear 123 is respectively connected to an output gear 121 and an intermediate gear 124. The intermediate gear 124 is connected to another output gear 121. As can be seen from the above, the motor 170 transmits power to the second-stage double gears 123 and the intermediate gear 124 on both sides of the motor 170 through the worm 180 and the first-stage double gears 122 on both sides of the worm 180, so as to drive the four output gears 121 on the frame 110 to rotate. This transmission structure makes the rotation directions of any two adjacent rockers 140 opposite, which can improve the massage effect of the massage head.

[0049] In an embodiment, the mating portion 1211 is provided with a polygonal slot 1212, and a protrusion 1213 is provided in the polygonal slot 1212. The first connecting portion 131 is a polygonal plug matching the shape of the polygonal slot 1212. A groove 1311 matching the shape of the protrusion 1213 is formed on the side of the polygonal plug facing the output gear 121.

[0050] As Figure 5 shown, in an embodiment of the present utility model, the mating portion 1211 is cylindrical and its central axis coincides with the axis of the output gear 121. A hexagonal slot is provided on the surface of the mating portion 1211 facing the transmission member 130. A columnar protrusion 1213 is provided at the bottom of the hexagonal slot. The shape of the first connecting portion 131 on the transmission member 130 is a hexagonal plug, and the shape of the hexagonal plug matches that of the hexagonal slot. A groove 1311 matching the shape of the protrusion 1213 is further formed on the surface of the first connecting portion 131 facing the output gear 121. The hexagonal plug is inserted into the hexagonal slot, and the columnar protrusion 1213 is inserted into the groove 1311, so as to connect the transmission member 130 with the output gear 121.

[0051] It can be understood that during the rotation of the output gear 121, a force is applied to the outer wall of the first connecting portion 131 of the transmission member 130 through the inner wall of the hexagonal slot to drive the transmission member 130 to rotate. Compared with providing an inclined hole on the output gear 121, in this solution, the force on the output gear 121 by the transmission member 130 is more uniform, and the mold structure of the output gear 121 is simpler, and the assembly between components is convenient and efficient. It should be noted that in some other embodiments of the present invention, the mating portion 1211 may be a polygonal slot such as a pentagon or an octagon, and the shape of the first connecting portion 131 may be correspondingly set according to the slot, and no specific limitation is made here.

[0052] In one embodiment, the output gear 121 and the transmission member 130 are integrally formed.

[0053] In an embodiment of the present invention, the output gear 121 and the transmission member 130 are integrally formed. Similarly, there is no need to provide an inclined hole on the output gear 121. Relatively speaking, the processing difficulty is lower. At the same time, the number of components of the movement assembly is reduced, and the installation structure is simplified. The integral formation of the output gear 121 and the transmission member 130 is also beneficial to improving the structural strength, so that the force transmitted to the rocker 140 is more stable and uniform, enhancing the massage effect of the massage head.

[0054] The present invention also provides a massager, which includes a massager movement assembly 100. The specific structure of the massager movement assembly 100 refers to the above embodiments. Since this massager adopts all the technical solutions of the above embodiments, it has at least all the beneficial effects brought by the technical solutions of the above embodiments, and will not be elaborated here one by one.

[0055] The above are only exemplary embodiments of the present invention, and do not limit the patent scope of the present invention. Any equivalent structural transformation made under the technical concept of the present invention by using the content of the specification and drawings of the present invention, or directly / indirectly applied in other related technical fields, is included in the patent protection scope of the present invention.
