The terms used in the specification of the present application are merely for describing specific embodiments and are not intended to limit the present application.Referring to FIGS. 1 to 2, a sex toy 100 according to an embodiment of the present application is illustrated. The sex toy 100 includes a shell 20 and one or more stimulation modules mounted in the shell 20.As shown in FIG. 1, the shell 20 is configured generally like a human hand that includes a palm and a plurality of fingers extending from the palm. Preferably, the shell 20 is a dual layer structure and includes an outer shell 22 and an inner shell 24 within the outer shell 22, the inner shell 24 may be made of hard materials such as plastic, metal, etc., and provide support to the stimulation modules mounted in the shell 20; and the outer shell 22 may be made of soft materials such as silicone, rubber, etc., to directly contact the male penis, such that the sex toy 100 has a high strength and a pleasing experience of use.Referring to FIG. 2, in the present embodiment, the stimulation modules include a first stimulation module 40, a second stimulation module 50, and a third stimulation module 60.The first, second and third stimulation modules 40, 50, 60 stimulate the male penis in different ways and can thus achieve better stimulation effects.As shown in FIG. 3, the first stimulation module 40 comprises a first motor 42, a vibration unit 44 and a transmission unit 46 connected between the first motor 42 and the vibration unit 44. The swing unit 44 includes a first swing arm 441 and a second swing arm 443 which are arranged substantially symmetrically to each other. During operation of the first motor 42, the first swinging web 441 and the second swinging web 443 are driven to swing close to or away from each other relative to the shell 20, thereby achieving an occlusion effect to occlude a sensitive part of the human body interposed between the first swinging web 441 and the second swinging web 443.As shown in FIG. 2, the second stimulation module 50 includes at least one second motor, which may be a vibration motor for generating high-frequency vibrations at the sensitive part of the human body located between the fingers. The second stimulation module 50 is inserted into the fingers of the shell 20 and is located adjacent to the fingertips. Preferably, the second stimulation module 50 includes a plurality of second motors, and each second motor is inserted into one of the fingers. The second motors may be inserted in some of the fingers or each of the fingers. During use, the first stimulation module 40 may operate independently, the second stimulation module 50 may operate independently, and the first and second stimulation modules 40, 50 may operate simultaneously.As shown in FIGS. 4 and 5, the third stimulation module 60 includes a third motor 62 having an output shaft 621, an eccentric gear 64 connected to the output shaft 621 of the third motor 62, and a swing rod 66 connected to the eccentric gear 64. The eccentric gear 64 has a rod 641 extending therefrom, the rod 641 being parallel to the output shaft 621 of the third motor 62. The swing rod 66 is generally perpendicular to the rod 641, with one end thereof rotatably mounted about the rod 641 and another end thereof embedded within the shell 20, particularly a portion of the outer shell 22 at the palm. Preferably, a head 661 is formed at the other end of the swing bar 66 having a larger diameter than other parts of the swing bar 66, thereby improving the stability of the connection between the swing bar 66 and the outer shell 22.Referring also to FIGS. 4 and 5, the output shaft 621 of the third motor 62 and the rod 641 of the eccentric gear 64 both extend along the X direction, and the swing rod 66 extends along the Z direction. During operation, the rotation of the third motor 62 is converted to revolvating the swing rod 66 about the output shaft 621 and then to a Z-direction reciprocating motion of the swing rod 66 and a portion of the outer shell 22 corresponding to the head 661 of the swing rod 66, because the swing rod 66 is constrained to move in the X and Y directions for engagement with the shell 20. At the same time, relative rotation is generated between the swing rod 66 and the rod 641. That is, the third stimulation module 60 makes a Z-direction reciprocating motion to drum a part of the human body abutting on the head 661.In other words, by the first stimulation module 40 of the first embodiment of the present application, in the form of vibrations, a kneeling function is achieved that simulates a human hand that holds and kneads the male genitals. Moreover, the present application also provides an alternative embodiment that achieves the clipping function also by sliding movement.Referring to FIGS. 6 to 11, a sex toy 100 according to a second embodiment of the present application is shown. The sex toy 100 has a stimulation chamber 100 aextending along a longitudinal direction. The sex toy 100 comprises at least two massage arms 11, 12 and a drive arrangement 2. The number of massage arms 11, 12 is at least two. That is, the number of massage arms 11, 12 may be two, three, four or more, and more massage arms 11, 12 have a larger contact area for the penis located in the stimulation chamber 100 a, which may provide sufficient stimulation and massage effect and improve the user experience of the product.The at least two massage arms 11, 12 include a first massage arm 11 and a second massage arm 12 respectively disposed on opposite sides of the stimulation chamber 100 a, and the driving assembly 2 is in torque transmission communication with the at least two massage arms 11, 12 to drive the first massage arm 11 and the second massage arm 12 to slide toward or away from each other, thereby changing a radial dimension of the stimulation chamber 100 aat a portion corresponding to the first massage arm 11 and the second massage arm 12.Note that, in this connection, the longitudinal direction refers to the extending direction of the stimulation chamber 100 a, i.e., the insertion direction of the male penis, and a radial direction refers to the direction perpendicular to the extending direction of the stimulation chamber 100 a.The sex toy 100 provided by the embodiments of the present application allows the first massage arm 11 and the second massage arm 12 to approach or move away from each other by the driving assembly 2, thereby changing the size of the radial dimension of the stimulation chamber 100 aat a portion corresponding to the first massage arm 11 and the second massage arm 12.On the one hand, the structure of the sex toy 100 offers a more individual and more comfortable stimulating massage experience with a simple and compact structure.On the other hand, the massage arms 11, 12 can exert a more comprehensive stimulating massage effect on the male penis located in the stimulation chamber 100a, which further improves the use experience of the product.Referring to FIGS. 8, 10 and 11, the drive assembly 2 includes a drive mechanism 21 having a rotation output shaft 2121 and a thrust member 220 screwed to the rotation output shaft 2121. The rotation output shaft 2121 drives the thrust member 220 to move along the longitudinal direction when rotating. Each of the first massage arms 11 and the second massage arms 12 includes at least one slider 13 slidably engaged with the pushing member 220 so that the pushing member 220 drives the slider 13 to slide in the radial direction when the pushing member 220 moves in the longitudinal direction.That is, the drive assembly 2 may convert a rotational movement into a linear movement, and the rotation of the rotational output shaft 2121 of the drive assembly 2 may drive the thrust member 220 to slide along the longitudinal direction of the stimulation chamber 100 a. By the slidable engagement between the pushing member 220 and the sliders 13 of the massage arms 11, 12, the sliders 13 are driven to slide along the radial direction perpendicular to the longitudinal direction, whereby the first massage arm 11 and the second massage arm 12 are driven to slide toward or away from each other along the radial direction.The present disclosure does not limit the manner in which the rotation is converted to linear motion. For example, the drive assembly 2 may be driven by a screw rod mechanism that converts the rotational movement of the screw rod into a linear movement of the thrust element 220 along the axial direction of the screw rod through a threaded connection between the threads on the screw rod and the thrust element 220.In particular, in one embodiment, referring to FIGS. 8, 10 and 11, the drive assembly 2 includes a transmission mechanism 23. the transmission mechanism 23 includes a longitudinally extending threaded rod 231 and a pin 232. The screw rod 231 is connected to the rotation output shaft 2121 and rotates synchronously with the rotation output shaft 2121. The outer periphery of the screw rod 231 has a spiral groove 231a. One end of the pin 232 is slidably fitted in the spiral groove 231a, and the other end of the pin 232 is fixed to the pushing member 220. The pushing member 220 is slidable together with the pin 232 but prevented from rotating. Thus, the rotation of the screw rod 231 drives the pin 232 in the spiral groove 231 ato slide linearly along the longitudinal direction, whereby the thrust member 220 fixed to the pin 232 is driven to slide linearly along the longitudinal direction. In particular, in one embodiment, the transmission mechanism 23 further comprises a stationary shell 233. The longitudinal end of the push element 220 remote from the massage arms 11, 12 is slidably nested within the stationary shell 233. The stationary shell 233 is used to prevent the pushing member 220 from rotating with the screw rod 231. For example, the sheath 233 may have a hole into which the longitudinal end of the pushing member 220 is slidably inserted. Preferably, the hole and the longitudinal end are positive locking so as to prevent relative rotation between the pushing element and the sheath. The hole may have a polygonal shape, for example, a quadrangular, pentagonal, or hexagonal shape.Alternatively, it is possible to use a cam mechanism to achieve torque transmission in which the thrust member 220 may be formed as a driven member driven by a cam. The pushing member 220 is driven to linear motion by the rotational motion of the cam. The specific shape of the cam may be adjusted to control the trajectory of the pushing member 220.Alternatively, it is also possible to use a rack and pinion mechanism to achieve torque transfer in which the rotation of the gear can drive an engaged rack to linear motion. In particular, the rotation of the gear can be converted into the linear movement of the gear rack by the meshing of gear teeth and gear rack. In this case, only a fixed connection between the rack and the thrust member 220 is required, the linear movement of the thrust member 220 can be achieved. Moreover, known crank slide mechanisms and other transmission mechanisms may also be used, which will not be described in detail here.In the present disclosure, the slider 13 slidably engages with the thrust member 220, but the manner in which the slider 13 is driven to slide in the radial direction when the thrust member 220 slides along the longitudinal direction is not particularly limited. By way of example, in one embodiment, the pusher element 220 is provided with a wedge and the pusher 13 has an inclined surface engageable with the wedge. When the pushing member 220 slides along the longitudinal direction, the wedge pushes the slider 13 and pushes the slider 13 by the engagement with the inclined surface, so that the slider 13 slides along the radial direction.In some embodiments, the slidable engagement between the pushing member 220 and the slider 13 is achieved via a slot 221 aor 221 band a protrusion 131. The slit 221 a, 221 bis formed on one of the pushing members 220 and the slider 13, and the protrusion 131 is formed on the other of the pushing members 220 and the slider 13. The protrusion 131 is slidably inserted into the slot 221a, 221b. The positions of the slit 221 a, 221 band the protrusion 131 are not limited. That is, if the pushing member 220 is provided with the slit 221 a, 221 b, the slider 13 is provided with the corresponding protrusion 131; if the pushing member 220 is provided with the protrusion 131, the slider 13 is provided with the corresponding slit 221 a, 221 b. In other words, the pushing member 220 and the slider 13 are slidably connected by the slit 221 a, 221 band the protrusion 131. When the pushing member 220 moves, the protrusion 131 slides in the slot 221 a, 221 band drives the slider 13 to move.In some embodiments, and referring to FIGS. 10, 11, and 16, the protrusion 131 is provided on the slider 13, and the pushing member 220 is provided with a first slot 221 aand a second slot 221 bwhich respectively correspond to the sliders 13 of the first massage arm 11 and the second massage arm 12. The first slot 221 aand the second slot 221 bare both inclined relative to the longitudinal direction.Specifically, a part of the pushing member 220 adjacent to the first massage arm 11 and the second massage arm 12 is substantially a plate-like structure, and the first slit 221 aand the second slit 221 bare both formed in the plate-like structure. The first slot 221 aand the second slot 221 bare both elongated. The protrusions 131 on the sliders 13 of the first massage arm 11 and the second massage arm 12 are both formed as posts extending along the vertical direction. The posts are inserted into the first slot 221 aand the second slot 221 b, respectively. Since both the first slot 221 aand the second slot 221 bare inclined relative to the longitudinal direction, the sliders 13 of the first massage arm 11 and the second massage arm 12 are guided by the first slot 221 aand the second slot 221 bwhen the pushing member 220 slides along the longitudinal direction, causing the sliders 13 to slide within the slots 221 a, 221 bin the radial direction, thereby achieving radial sliding of the first massage arm 11 and the second massage arm 12.In some embodiments, the first slot 221 aand the second slot 221 bgradually extend closer to each other or gradually away from each other along the longitudinal direction. That is, the radial distance between the first slot 221 aand the second slot 221 bgradually decreases or increases.For example, the extending direction of the first slot 221 amay be parallel to the longitudinal direction, and the extending direction of the second slot 221 bis inclined at an angle relative to the extending direction of the first slot 221 a. Alternatively, the extending direction of the second slot 221 bmay be parallel to the longitudinal direction, while the extending direction of the first slot 221 ais inclined at an angle relative to the extending direction of the second slot 221 b.Further, in some embodiments, referring to FIGS. 10, 11, and 16, neither the extending direction of the first slot 221 aor the extending direction of the second slot 221 bis parallel to the longitudinal direction, the first slot 221 aand the second slot 221 bare arranged in a V shape or a V shape. Accordingly, there is an angle between the extending direction of the first slot 221 aand the extending direction of the second slot 221 b. The angle range is not particularly limited, but may be set larger than 0 degrees and smaller than 180 degrees as appropriate. For example, the angle may be 30 degrees, 60 degrees, 90 degrees, 120 degrees, 150 degrees, etc. In the case of a V-shaped arrangement, an axial end of the first slot 221 aand an axial end of the second slot 221 bcross; and the other end of the first slot 221 aand the other end of the second slot 221 bare spaced apart from each other.In some embodiments, and with reference to FIGS. 7 and 8, the drive mechanism 21 includes a fourth motor 211 and a transmission assembly 212. An input end of the transmission assembly 212 is in torque transmission communication with a rotation shaft 211 aof the fourth motor 211. The rotary output shaft 2121 is configured as an output end of the transmission assembly 212. The transmission assembly 212 can adjust the output speed of the rotary output shaft 2121 and increase the output torque, which can improve the control precision of the sex toy 100 and reduce the workload of the fourth motor 211, thereby achieving more stable stimulation of the male penis, and ensure the reliability of the sex toy and the product experience of the usersIn some embodiments, and with reference to FIGS. 6 through 11, the sex toy 100 is constructed entirely as a claw-like structure. The sex toy 100 further comprises a housing 4. the at least two massage arms 11, 12 are arranged on two sides of the housing 4, respectively. One end of each of the massage arms 11, 12 is slidably connected to the housing 4, and distal ends of the first massage arm 11 and the second massage arm 12 extend out of the housing 4 and extend toward each other. Preferably, the distal ends of the first massage arm 11 and the second massage arm 12 are curved toward each other. The at least two massage arms 11, 12 and the housing 4 enclose the stimulation chamber 100 a. In particular, the housing 4 comprises an upper housing 4 band a lower housing 4 c, which are connected to one another, for example, by snap-fit. The housing 4 defines therein a mounting cavity 4a, and the drive assembly 2 is disposed in the mounting cavity 4a of the housing 4.In some embodiments, and with reference to FIGS. 10, 11 and 16, the sex toy 100 further comprises a guide member 3, wherein the guide member 3 is fixedly arranged to guide the sliding direction of the slider 13. The guide member 3 has a guide slot 3a corresponding to the slider 13 to receive it. The guide slot 3a extends substantially in the radial direction. In particular, the guide element 3 has a groove structure. The guide member 3 may be fixed to the housing 4 to ensure that the guide member 3 is fixed relative to the housing 4. The housing 4 includes, but is not limited to, hard plastics such as polypropylene (PP), polyvinyl chloride (PVC), polycarbonate (PC), etc. Thus, it provides structural support for the components received therein.The guide slot 3a extends substantially in the radial direction, which means that the extending direction of the guide slot 3a and the radial direction may be the same or have a slight angle. The angle range is not particularly limited, but may be set between greater than or equal to 0 degrees and less than or equal to 20 degrees as needed, for example, the angle is 0 degrees, 10 degrees, 20 degrees, etc. For example, in one embodiment, an end of the guide member 3 away from the massage arm 1 is open to form a guide slot 3 aextending in the radial direction, and the slider 13 is slidably inserted into the guide slot 3 aand thus slidable along the radial direction. The guide member 3 enhances the stability of the sliders 13 in sliding in the radial direction.In some embodiments, and referring to FIG. 6 a, the distal ends of the first massage arm 11 and the second massage arm 12 may be connected to each other by a flexible member 93. The flexible member 93 includes, but is not limited to, stretchable and soft silicone or the like.
