Referring to FIG. 1 to FIG. 4, a stimulation device 100 according an embodiment of the present application is shown. In this embodiment, the stimulation device 100 includes a shell 20 and first and second stimulation modules 30, 40 mounted in the shell 20.

As shown in FIG. 1 and FIG. 2, the shell 20 includes a main portion 22 and two stimulation portions 24 extending out from the main portion 22. Preferably, the shell 20 is a double-layer structure, and includes an outer shell 20a and an inner shell 20b inside the outer shell 20a. The inner shell 20b may be made of hard materials, such as plastic, metal and etc., providing support to the stimulation modules 30, 40 mounted inside the shell 20; and the outer shell 20a may be made of soft materials, such as silicone, rubber and etc., for directly contacting a part of the human body which needs to be stimulated, thereby the stimulation device 100 in whole has high strength and comfortable use experience.

Referring to FIGS. 4-6, the first stimulation module 30 is generally mounted in the main portion 22 of the shell 20, and includes a first motor 31, a swinging unit 32 and a transmission unit 33 connected between the first motor 31 and the swinging unit 32 in a transmission way. In this embodiment, the first motor 31 is a rotary motor, and has a rotary shaft 311 extending out for outputting torque. The transmission unit 33 is configured for converting rotation of the first motor 31 into linear reciprocating motion in a first direction, such as in X-direction, and in turn driving the swinging unit 32 to swing about an axis extending in a second direction, such as in Y-direction.

In this embodiment, the transmission unit 33 includes a rotary member 34, a fixing member 35 and two sliding members 36.

The rotary member 34 is connected to the rotary shaft 311 of the first motor 31 at a central portion thereof, so as to rotate along with the rotary shaft 311. In this embodiment, a cross section of the rotary shaft 311 is generally non-circular shaped, such as D-shaped, polygonal-shaped, irregularly shaped and etc. The rotary member 34 defines a central hole 341 at the central portion thereof for receiving the rotary shaft 311, which has a shape matching with that of the rotary shaft 311. After inserting of the rotary shaft 311 into the central hole 341, a relative rotation between the rotary member 34 and the first motor 31 is limited for shape matching.

A first groove 343 is defined in the rotary member 34 at a side thereof facing towards the sliding members 36. The first groove 343 is generally non-circular shaped, and in this embodiment, is elliptical-shaped. Specifically, the rotary shaft 311 extends in a third direction, such as in Z-direction; and the first groove 343 is formed in a plane perpendicular to the rotary shaft 311, such as in XY plane. The first groove 343 is symmetric about a rotary axis of the rotary member 34 which is, preferably collinear with that of the rotary shaft 311. During operation of first motor 31, the rotary member 34 rotates together with the rotary shaft 311 in the XY plane, and a position of the first groove 343 in the XY plane is changed periodically.

The fixing member 35 is fixed inside the shell 20, and a second groove 351 is defined in the fixing member 35 at a side thereof facing towards the sliding members 36. The second groove 351 is linear-shaped and elongated in a radial direction of the first groove 343. In this embodiment, the second groove 351 extends along the X-direction, and is configured that relative movement of the sliding members 36 to the fixing member 35 in the X-direction is allowed, and relative movement of the sliding members 36 to the fixing member 35 in the Y-direction is not allowed.

The two sliding members 36 are arranged symmetric to each other in the X-direction. Each of the sliding members 36 includes a first sliding portion 361 engaged into the first groove 343 of the rotary member 34 and a second sliding portion 363 engaged into the second groove 351 of the fixing member 35. The first sliding portion 361 may slide along the first groove 343 to generate movement relative to the rotary member 34, and the second sliding portion 363 may slide along the second groove 351 to generate movement relative to the fixing member 35.

During rotation of the rotary member 34 along with the first motor 31, the first sliding portions 361 of the sliding members 36 engaged into the first groove 343 of the rotary member 34 have a tendency to move in both of the X-direction and the Y-direction. However, the second sliding portions 363 of the sliding members 36 engaged into the second groove 351 of the fixing member 35 limit the movement of the sliding members 36 in the Y-direction. Thus, the sliding members 36 are merely able to do linear reciprocating motion in the X-direction, and a relative movement between the sliding members 36 and the rotary member 34 in the Y-direction is generated since the elliptical-shaped first groove 343 of the rotary member 34 allows generating such motion.

Taking the shell 20 as reference, the rotary member 34 generates movement in both the X-direction and Y-direction, the fixing member 35 keeps still, and the sliding members 36 generate movement in the X-direction. Relative movement in the Y-direction is generated between the sliding members 36 and the rotary member 34, and relative movement in the X-direction is generated between the sliding members 36 and the fixing member 35. Finally, rotation of the first motor 31 is converted into liner reciprocating motion of the sliding members 36 in the X-direction. For the symmetrical construction of the two sliding members 36 in the X-direction, they move towards each other or away from each other.

Referring to FIG. 5 and FIG. 6, the swinging unit 32 includes two swinging bars 321 being arranged substantially symmetric to each other in the X-direction. Each of the two swinging bars 321 is rotatably connected to the fixing member 35 by a first pivot 37 which extends along the Y-direction. In this embodiment, the fixing member 35 is formed separately and then fixedly assembled into the inner shell 20b. In other embodiments, the fixing member 35 may be integrally formed with the inner shell 20b as one piece. That is, the fixing member 35 may be regarded as a portion of the inner shell 20b, and the swinging bars 321 may be rotatably connected to the inner shell 20b by the first pivots 37.

In this embodiment, the fixing member 35 forms a pair of support arms 353 at each end of the second groove 351 for connecting the swinging bar 321. Each pair of support arms 353 are respectively located at two opposite lateral sides of the corresponding end of the second groove 351, and define connecting holes 355 therein. Two ends of the first pivot 37 are inserted into the connecting holes 355 of the corresponding pair of the support arms 353, respectively. The first pivot 37 may be formed separately and then assembled to the swinging bar 321 and the support arms 353, or may be integrally formed with the swinging bar 321 or the support arms 353.

Each swinging bar 321 cooperates with one of the two sliding members 36. Specifically, one end of the swinging bar 321 is rotatably connected to a corresponding sliding member 36 by a second pivot 38 which extends along the Y-direction, and another end of the swinging bar 321 is configured as a stimulation end 323 and extends into one of the stimulation portions 24 of the shell 20. The stimulation ends 323 of the two swinging bars 321 are opposite to each other in the X-direction, and swing towards or away from each other during linear reciprocating motion of the sliding members 36.

Specifically, when the two sliding members 36 are driven to do linear reciprocating motion in the X-direction, each of the two swinging bars 321 is forced to swing about the first pivot 37 which extends along the Y-direction, wherein swinging directions of the two swinging bars 321 are opposite. When the sliding members 36 move towards each other, the stimulation ends 323 of the two swinging bars 321 swing away from each other; and when the sliding members 36 move away from each other, the stimulation ends 323 swing towards each other. The two stimulation portions 24 of the shell 20 swing together with the two stimulation ends 323 of the first stimulation module 30, so as to produce an occlusion action to a part of the human body put between the stimulation portions 24, or slap a part of the human body placed around the stimulation portions 24, thereby obtaining better stimulation effects.

In this embodiment, a third groove 357 is defined in the fixing member 35 for engagement of the first sliding portion 361 of the sliding member 36 into the first groove 343 of the rotary member 34. As shown in FIG. 6, the third groove 357 extends through a portion of the fixing member 35 at a bottom of the second groove 351, and has a width in the Y-direction less than that of the second groove 351. When the second sliding portion 363 is mounted into the second groove 351, the first sliding portion 361 extends through the third groove 357 into the sliding groove of the rotary member 34.

In this embodiment, the first sliding portion 361 of the sliding member 36 is generally column-shaped, which extends along the Z-direction and has a diameter slightly less than widths of the first groove 343 and the third groove 357 in the Y-direction, thereby the first sliding portion 361 can slide along the first groove 343 and the third groove 357 smoothly. The second sliding portion 363 of the sliding member 36 is generally block-shaped, and has a width in the Y-direction being slightly less that of the second groove 351 but greater than that of the third groove 357, thereby the second sliding portion 363 can slide along the second groove 351 smoothly.

In this embodiment, a position portion 365 extends radially and outwardly from an end of the first sliding portion 361 adjacent to the second sliding portion 363. The position portion 365 has a width in the Y-direction greater than that of the third groove 357. After assembled, the position portion 365 and the second sliding portion 363 are located at opposite sides of the third groove 357, and thus the sliding member 36 is positioned in the Z-direction. For facilitating assembly of the sliding members 36 to the fixing member 35, a through hole 356 is defined in the fixing member 35 with a diameter greater than the width of the position portion 365 in the Y-direction. Preferably, the through hole 356 is formed at a middle of the third groove 357.
