[0022] Please see Figures 1 to 3 , Figure 1 A schematic diagram illustrating the massage device 100 of the first embodiment of this utility model; Figure 2 To illustrate according to Figure 1 Exploded view of the massage device 100 of the embodiment; Figure 3 To illustrate according to Figure 1 A cross-sectional view of the massage device 100 of the embodiment. The massage device 100 includes a housing 110, a power module 120, two massage assemblies 130a and 130b, and an adjustment assembly 140. The housing 110 may include a first housing 111 and a second housing 112. The second housing 112 is connected to the first housing 111 and forms an accommodating space 113. The second housing 112 includes two through holes 1121 for the two massage assemblies 130a and 130b to pass through. The power module 120 is fixed to the first housing 111 and is located within the accommodating space 113.

[0023] The power module 120 is housed within the housing 110 and includes a motor 121, two screws 122, a circuit board 123, a battery 124, a motor base 125, and a motor base gasket 126. The two screws 122 are connected to and driven by the motor 121 to rotate. The battery 124 is electrically connected to and supplies power to the motor 121. The circuit board 123 is electrically connected to both the battery 124 and the motor 121 to control the rotation speed of the motor 121. The motor base 125 is connected to the housing 110 and houses the motor 121. Specifically, the motor 121 is mounted on the motor base 125, and the two screws 122 are connected to both ends of the motor 121. When the motor 121 rotates, the two screws 122 are driven to pivot synchronously.

[0024] Each of the two massage assemblies 130a and 130b includes a gear set 131 and a massage disc 132. The gear set 131 is disposed within the housing 110 and connected to a screw 122, wherein the gear set 131 rotates as the screw 122 rotates. The massage disc 132 is disposed outside the housing 110 and is connected to and rotates with the gear set 131. The gear set 131 includes a first gear 131a and a second gear 131b. The first gear 131a meshes with the screw 122 and is driven to rotate by the screw 122. When the screw 122 is driven to rotate by the motor 121, the first gear 131a is pushed to rotate by the screw 122, thereby driving the second gear 131b to rotate. In this way, the massage device 100 of this invention can drive the massage disc 132 to oscillate.

[0025] The adjustment assembly 140 includes an adjustment gear 141 and two racks 142 and 143. The two racks 142 and 143 are located on opposite sides of the adjustment gear 141 and mesh with it. The two racks 142 and 143 are respectively connected to two massage assemblies 130a and 130b. As the adjustment gear 141 rotates, the racks 142 and 143 change the distance between the two massage assemblies 130a and 130b. The two massage assemblies 130a and 130b move closer to or further apart as the adjustment gear 141 rotates.

[0026] Specifically, the adjusting gear 141 is positioned between the two massage assemblies 130a and 130b. Figure 3In this design, two racks 142 and 143 are respectively positioned on the upper and lower sides of the adjusting gear 141 and are connected to the first cover 134a of the two massage assemblies 130a and 130b. When the adjusting gear 141 rotates clockwise, rack 142 moves to the right and rack 143 moves to the left, thereby moving the two massage assemblies 130a and 130b away from the adjusting gear 141. When the adjusting gear 141 rotates counterclockwise, rack 142 moves to the left and rack 143 moves to the right, thereby moving the two massage assemblies 130a and 130b closer to the adjusting gear 141. Therefore, the massage device 100 of this invention can be suitable for users of different body types and can be flexibly applied to massage different muscle areas.

[0027] Please see Figures 1 to 4 ,in Figure 4 To illustrate according to Figure 1 A side view of the massage device 100 of the embodiment. The massage device 100 may further include a fixing plate 144, an adjusting knob 145, a gear shaft 146, and an elastic member 147. The side of the fixing plate 144 facing the racks 142 and 143 includes teeth, and the side of the racks 142 and 143 facing the fixing plate 144 also includes teeth. The fixing plate 144 is engaged with the teeth of the racks 142 and 143 by the elastic member 147. The gear shaft 146 passes through the central through hole of the adjusting gear 141. The adjusting knob 145 is connected to one end of the gear shaft 146. The gear shaft 146 drives the adjusting gear 141 to rotate as the adjusting knob 145 rotates. The adjusting knob 145 is disposed in the first housing 111 and located outside the accommodating space 113. In other words, the fixing plate 144 can be used to fix the adjusting gear 141 to the second housing 112, and the adjusting knob 145 can be rotated by the user and drive the adjusting gear 141 to rotate through the gear shaft 146, thereby adjusting the distance between the two massage assemblies 130a and 130b.

[0028] In other embodiments of this invention, the adjusting gear has a shaft with the shaft protruding from it. An adjusting knob is connected to the shaft of the adjusting gear and is used to drive the adjusting gear to rotate. The user can press the adjusting knob to contact the adjusting gear and then rotate the knob to adjust the distance between the two massage components.

[0029] Please see Figures 1 to 5 ,in Figure 5 To illustrate according to Figure 1An exploded view of the massage assembly 130a of the massage device 100 of the embodiment. The massage assembly 130a may further include a positioning pin 133, a first cover 134a, and a second cover 134b. The massage disc 132 may further include a first massage element 132a, a second massage element 132b, a fixing member 135, a swing arm 136, and a connecting member 137. The second cover 134b is connected to the first cover 134a and includes an opening 1341. The structure of the massage assembly 130b may be similar to or the same as that of the massage assembly 130a, and therefore will not be described in detail.

[0030] A positioning pin 133 passes through the shaft of the second gear 131b. The gear set 131 also includes a positioning part 1311. When the gear set 131 is driven to rotate by the power module 120, the positioning pin 133 contacts the positioning part 1311 and pivots coaxially. Specifically, when the first gear 131a drives the second gear 131b to rotate, the positioning pin 133 does not immediately rotate with the second gear 131b. Only after the positioning part 1311 of the second gear 131b rotates to contact the positioning pin 133 will the positioning pin 133 drive the massage plate 132 to swing. Thus, the massage device 100 of this utility model can provide a positioning pin 133 in at least one of the massage assemblies 130a and 130b, so that the massage assemblies 130a and 130b swing asynchronously.

[0031] In other embodiments of this utility model, the massage assemblies 130a and 130b may not be provided with positioning pins, so the massage assemblies 130a and 130b can swing synchronously.

[0032] Furthermore, the swing arm 136 is connected to the positioning pin 133. A first massage member 132a is disposed at one end of the swing arm 136. A second massage member 132b is disposed at the other end of the swing arm 136. The end of the swing arm 136 connected to the first massage member 132a pivots coaxially with the second gear 131b.

[0033] Although the present invention has been disclosed above by way of embodiments, it is not intended to limit the present invention. Any person skilled in the art can make various modifications and refinements without departing from the spirit and scope of the present invention. Therefore, the scope of protection of the present invention shall be determined by the appended claims.
