Description

Technical Field

[0001] The present invention relates to the technical field of adult products, and particularly to a multi-stage telescopic adjustment mechanism with two types of stimulation methods.

Background Art

[0002] Adult products are designed for adults and aim to satisfy physiological desires, enhance emotional satisfaction or improve intimate experiences. Their usage scenarios and functions are clearly targeted at adults and are not suitable for use by minors. By having a multi-stage telescopic adjustment function, users can adjust the length and shape of the passage inside the sex doll according to their preferences and sensitivities, and can gradually change the wrapping feeling and frictional feeling. For example, when wanting to obtain a stronger stimulation, by adjusting to a specific stage, the internal structure can be made denser to enhance the stimulation. When desiring a milder experience, by adjusting to other stages, the layout of the internal space can be changed to obtain different touches. However, in some sex dolls in the prior art, it is difficult to achieve two types of stimulation methods, and users feel that there is a lack of responsive touch, resulting in a problem of reduced richness and realism of the experience. A structure that can realize two types of stimulation actions can flexibly adapt to differences in users' physical conditions and usage habits, and improve stability by facilitating the position holding of the sex doll. Without such a structure, there is a lack of stability during use, and users need to exert extra effort to maintain their positions. In particular, for those with special physical conditions or specific usage habits, comfort and convenience may be compromised.

[0005] This invention provides the following beneficial effects. 1. In this invention, a geared motor provides driving force, causing the second disc to rotate. As the cylinder on the second disc rotates, the limit frame slides along the support column. The limit rods on both sides of the limit frame are fitted into grooves in the left and right first oscillating arm units. As the limit frame slides, the first oscillating arm units perform a reciprocating opening and closing motion around a fixed axis. The action of these oscillating arm units and the vibration motor causes the interlocking soft rubber on the outside of the annular base to be pressed and released, and the interlocking soft rubber changes shape to achieve gripping and improve the degree of contact with the object being contacted. 2. In this invention, when the 130 motor is started, the motor's rotation rotates the eccentric gear via gear transmission, causing the first disc to rotate synchronously. The cylinder on the first disc performs circular motion, continuously applying a periodic thrust to the annular groove frame. As a result, the slide sleeve performs stable reciprocating linear motion along the slide steel shaft, and the reciprocating sliding soft rubber inside the slide sleeve also moves synchronously, enabling expansion and contraction movements of different strokes and simulating dynamic depth changes.

[0007] The technical means of embodiments of the present invention will be clearly and completely described below with reference to the drawings of the specification. Clearly, the embodiments described are only some, not all, embodiments of the present invention. All other embodiments obtained by those skilled in the art without creative ingenuity based on the embodiments of the present invention are within the scope of the protection of the present invention.

[0008] As shown in Figures 1 and 2, the multi-stage telescopic adjustment mechanism with two types of stimulation methods according to an embodiment of the present invention includes two decorative covers 1. The decorative covers 1 function as protective and decorative members for the outside of the mechanism, completely covering the gap at the joint of the two outer shells 2, preventing the intrusion of dust, moisture, and fine foreign matter from the outside, and preventing corrosion of internal components. They also unify the external design, prevent the internal structure from being exposed and impairing the aesthetics, and absorb shock when a slight external force is applied to the mechanism, protecting the internal outer shells 2. The outer shells 2 are fixedly connected to the sides of the two decorative covers 1 that are close to each other. A support sleeve body 3 is fixedly connected to the sides of the two outer shells 2 that are close to each other. Multiple mounting holes for fixing the slide steel shaft 59 are machined inside the support sleeve body 3, providing guide support for the reciprocating slide of the slide sleeve 510 in the motion mechanism 5, and ensuring the linearity and stability of the telescopic movement. An operation button mechanism 4 is installed on the front side of the support sleeve body 3. The operation button mechanism 4 is the main interface for the user to operate the mechanism. Pressing the silicon button 41 switches the internal circuit on and off, transmitting the user's operation command as an electrical signal to the control unit. The control unit adjusts the operating parameters of the motion mechanism 5 and the occlusal vibration mechanism 6 based on the received signal. The motion mechanism 5 is installed on the rear side of the support sleeve body 3. The motion mechanism 5 is the main execution module that realizes the multi-stage telescopic function of the mechanism. It reduces and increases the torque of the output from the 130 motor 52 using a gear set to rotate the first disc 55, and converts this rotational motion into reciprocating linear motion of the slide sleeve 510 along the slide steel shaft 59. By utilizing the multi-stage limit structure of the slide steel shaft 59, it is possible to switch between different telescopic strokes and realize dynamic simulation of depth changes. An occlusal vibration mechanism 6 that performs reciprocating clamping motion is installed inside the bottom of the two outer shell bodies 2. The occlusal vibration mechanism 6 is supplied with a stable driving force by the first geared motor 62, which causes the first oscillating arm unit 66 to reciprocate by opening and closing via the transmission components. The first oscillating arm unit 66 presses against the occlusal soft rubber 612 on the annular base 611, generating a clamping action, which increases the degree of contact between the mechanism and the object it is contacting, and ensures the reliability and stability of the clamping operation.

[0009] As shown in Figures 3 to 5, the occlusal vibration mechanism 6 includes a box 61. The bottom of the box 61 is fixed to the inner bottom walls of the two outer shells 2. Inside the box 61 is a first geared motor 62, which is the drive source for the occlusal vibration mechanism 6. The motor has a built-in reduction gear set that converts high rotation and low torque to low rotation and high torque, providing sufficient driving force for the clamping operation, enabling the first oscillating arm unit 66 to stably clamp the occlusal soft rubber 612. Furthermore, the motor can adjust its rotational speed according to the control signal, making it possible to change the frequency and force of the clamping operation. A second disc 63 is fixed to the drive end of the first geared motor 62. The second disc 63 is the primary important component in power transmission from the motor 62. The second disc 63 is rigidly coupled to the drive end of the motor via a central hole, completely transmitting the rotational motion of the motor. Furthermore, the second cylinder 64, fixed to the front of the second disc 63, converts rotational motion into a driving force that slides the limit frame 68, preventing power transmission losses. The planar structure of the second disc 63 ensures the stability of the movement trajectory of the second cylinder 64. The second cylinder 64 is fixed perpendicularly to the front edge of the disc 63 and performs circular motion as the disc rotates. During motion, its outer circumference contacts the limit frame 68, applying thrust and converting the circular motion into linear motion of the limit frame 68 along the support column 67. The cylindrical structure of the second cylinder 64 reduces contact friction with the limit frame 68, ensuring smooth propulsion and preventing jamming. Fixed shafts 65 are fixed to both the left and right sides inside the box body 61. The fixed shafts 65 are the pivot points of the first swing arm unit 66. Both ends of the fixed shaft are fixed to fixing holes in the left and right inner walls of the box body 61, and the first swing arm unit 66 is always supported to rotate around the fixed shaft 65 during opening and closing movements, preventing any displacement or looseness.

[0010] As shown in Figure 8, a first oscillating arm unit 66 is rotatably connected to the outside of each fixed shaft 65. The first oscillating arm unit 66 is a component that directly performs the clamping motion. One end is rotatably connected to the fixed shaft 65 via an axial hole, and the other end extends inside the occlusal soft rubber 612. Driven by the limit frame 68, it performs a reciprocating opening and closing oscillation around the fixed shaft 65. During the oscillation motion, the outer wall of the oscillating arm itself and the vibration motor 610 press and release the occlusal soft rubber 612, causing a change in shape in the occlusal soft rubber 612 and achieving clamping. The length and oscillation angle of the oscillating arm 66 are precisely designed to ensure that the clamping range of the occlusal soft rubber 612 is as designed. A support limit component 613 is fixed inside the box body 61. The limit component 613 forms the core of the transmission coupling of the occlusal vibration mechanism 6 and consists of a support column 67, a limit frame 68, and a limit rod 69. The support column 67 provides a sliding guide to the limit frame 68, preventing displacement when the limit frame 68 slides. The limit frame 68 receives the thrust from the cylinder 64 and transmits it to the limit rod 69. The limit rod 69 converts the linear motion into the oscillating motion of the first oscillating arm unit 66, maintaining a stable and efficient power transmission path from the motor to the first oscillating arm unit 66. An annular base 611 is fixed to the upper part of the box body 61. The annular base 611 is the base for mounting and supporting the occlusal soft rubber 612. Its outer wall is in close contact with the inner wall of the occlusal soft rubber 612, preventing displacement after the soft rubber is fixed. Furthermore, the annular structure of the annular base 611 provides uniform support force to the occlusal soft rubber 612, ensuring that the soft rubber deforms uniformly along the annular shape when pressed by the first oscillating arm unit 66, thereby ensuring symmetry and stability of the clamping operation. A vibration motor 610 is fixed to the outside of one of the first oscillating arm units 66. The motor 610 is mounted at a specific position on the first oscillating arm unit 66. Its main role is to increase the contact area between the oscillating arm 66 and the occlusal soft rubber 612, preventing localized wear of the soft rubber due to single-point contact. It also evenly distributes the pressure applied to the occlusal soft rubber 612 by the oscillating arm 66, uniformizing the deformation of the soft rubber 612 and improving the adhesion and reliability of the clamping.

[0011] An occlusal soft rubber 612 is attached to the outside of the annular base 611. The occlusal soft rubber 612 is made of an elastic material and is a component that comes into direct contact with the object to be clamped. It achieves the clamping action through its own elastic deformation, preventing damage to the object to be clamped due to rigidity, and improving the feeling of contact and adhesion by filling in minute irregularities on the surface of the object to be clamped through deformation. In addition, the soft rubber material has a certain degree of wear resistance, extending the service life of the clamping component and ensuring the stability of the clamping performance even after long-term use. The limit component 613 includes two support columns 67. The support columns 67 are fixed vertically to the inner wall of the bottom of the box body 61, and the two support columns 67 are arranged in parallel, with a spacing that matches the width of the limit frame 68. The outer walls of the support columns 67 are smoothly processed to reduce frictional resistance with the inner wall of the limit frame 68, allowing the limit frame 68 to slide smoothly along the support columns 67. Furthermore, the support columns 67 have sufficient rigidity to prevent bending or deformation when the limit frame 68 is propelled. The exteriors of the two support columns 67 are fixed inside the box body 61, and the limit frame 68 is slidably connected to the exteriors of the support columns 67. The limit frame 68 is the core transmission member of the limit component 613, and has a sliding hole inside that fits the support columns 67, allowing it to slide linearly along the support columns 67. The front side contacts the second cylinder 64 to receive thrust, and both sides are connected to the first oscillating arm unit 66 via limit rods 69, converting linear motion into oscillating motion by the first oscillating arm unit 66. Limit rods 69 are fixed inside both the front and rear sides of the limit frame 68. The limit rods 69 have a cylindrical structure and are fixed to the front and rear sides of the limit frame 68, with their intermediate portions fitting into the sliding grooves of the first oscillating arm unit 66. As a result, when the limit frame 68 slides, the limit rod 69 moves within the slide groove, causing the first swing arm unit 66 to rotate around the fixed shaft 65.

[0012] As shown in Figures 1 and 2, the button mechanism 4 includes a silicone button 41. The rear side of the silicone button 41 is attached to the front side of the two outer shells 2, and a button decorative member 42 is fixed to the front side of the silicone button 41. The button decorative member 42 covers the front surface of the silicone button 41 and is made of a hard material. On the one hand, it protects the silicone button 41 from damage caused by external friction and impact, extending its lifespan. On the other hand, it clarifies the function of the button by applying markings such as printing or engraving to the surface, making it easy for the user to recognize its operation. A button light-shielding cover 43 is fixed to the outside of the button decorative member 42. The light-shielding cover 43 has an annular structure, allowing the user to clearly recognize the button and perform accurate pressing operations, and ensuring the stability of command input.

[0013] As shown in Figures 2, 6, and 7, the motion mechanism 5 includes a gearbox housing 51 for the reciprocating sliding mechanism. The front of the gearbox housing 51 is fixedly connected to the rear of the support sleeve body 3, and a Type 130 motor 52 is fixed to its right inner wall. The Type 130 motor 52 is the power source for the motion mechanism 5 and can adjust its output rotational speed and direction of rotation according to a signal from the control unit, supplying continuous power to the gear train. The output shaft is rigidly connected to the first sub-gear 53, and the rotational power is transmitted directly to the first sub-gear 53, ensuring highly efficient and low-loss power transmission. The first sub-gear 53 is rotatably connected inside the gearbox housing 51 for the reciprocating sliding mechanism. The first sub-gear 53 is the first stage transmission gear of the motion mechanism 5, and its number of teeth and module are precisely designed. The output shaft of the 130 motor 52 is fixedly connected to the second sub-gear 54, converting the motor's high rotational speed to a rotational speed suitable for the second sub-gear 54, while simultaneously changing the direction of power transmission so that power is efficiently transmitted to the second sub-gear 54. Inside the gearbox housing 51 for the reciprocating sliding mechanism, the second sub-gear 54 is rotatably connected. The second sub-gear 54 is the second stage transmission gear of the motion mechanism 5, and has more teeth than the first sub-gear 53, which can further reduce the transmission speed and increase torque. The second sub-gear 54 meshes with the first sub-gear 53 and the eccentric gear 56, acting as an intermediate gear and accurately transmitting the power transmitted from the first sub-gear 53 to the eccentric gear 56. The first disc 55 is rotatably connected to the front inner wall of the gearbox housing 51 for the reciprocating sliding mechanism. The rear side of the first disc 55 is fixedly connected to the eccentric gear 56 and rotates in sync with the eccentric gear 56. The first cylinder 58, fixed to the front edge, moves in a circular motion together with the first disc 55, transmitting the rotational motion of the eccentric gear 56 to the annular groove frame 511 as a periodic thrust, driving the reciprocating motion of the slide sleeve 510. The flatness of the first disc 55 is precisely controlled to ensure that the movement trajectory of the first cylinder 58 is a perfect circle, preventing uneven thrust from causing the slide sleeve 510 to malfunction. The eccentric gear 56 is fixedly connected to the rear side of the first disc 55. The eccentric gear 56 is the final transmission gear of the motion mechanism 5 and receives power by meshing with the second sub-gear 54.The number of teeth on the eccentric gear 56 matches that of the second sub-gear 54, allowing it to stably receive power transmitted from the second sub-gear 54 and rotate the first disc 55. Furthermore, the rear side of the eccentric gear 56 is in contact with a washer 57, reducing friction with the inner wall of the gearbox housing 51 for the reciprocating sliding mechanism during rotation, ensuring smooth rotation and preventing power loss and overheating of components due to excessive friction. The washer 57 is fixedly connected to the rear side of the eccentric gear 56, extending the lifespan of both the eccentric gear 56 and the housing.

[0014] A first cylinder 58 is fixedly connected to the front side of the first disc 55. The first cylinder 58 is fixed perpendicularly to the front edge of the first disc 55. When the first disc 55 rotates, the first cylinder 58 performs circular motion, and its outer wall is constantly in contact with the inside of the annular groove frame 511. This applies periodic thrust and tactile forces to the annular groove frame 511, causing the annular groove frame 511 to reciprocate along the slide sleeve 510. At the same time, the outer wall of the first cylinder 58 must be smooth to reduce frictional resistance when in contact with the annular groove frame 511 and to ensure that thrust is transmitted stably. Multiple slide steel shafts 59 are fixedly connected inside the support sleeve body 3. The slide steel shafts 59 are guide members for the slide sleeve 510, and are manufactured as high-precision linear shafts with highly smooth surfaces. Multiple slide steel shafts 59 are arranged parallel and evenly inside the support sleeve body 3, providing a linear sliding trajectory for the slide sleeve 510 and restricting its direction of motion. Limit projections provided at specific positions on the shafts enable multi-stage stroke restriction, allowing the slide sleeve 510 to reciprocate within different stroke ranges and satisfying the multi-stage extension and retraction requirements of the mechanism. The slide sleeve 510 is slidably connected to the outside of the multiple slide steel shafts 59. The slide sleeve 510 is the executing member of the extension and retraction movement of the motion mechanism 5, and has a sliding hole machined inside to fit the slide steel shaft 59, allowing it to slide smoothly along the slide steel shaft 59. An annular groove frame 511 is fixed to the outside and receives the thrust of the first cylinder 58, and a reciprocating sliding soft rubber 512 is fixed inside, moving in sync with the reciprocating linear motion of the slide sleeve 510. The annular groove frame 511 is an annular structure mounted on the outside of the slide sleeve 510 and is rigidly connected to the slide sleeve 510. The periodic thrust of the first cylinder 58 is evenly transmitted to the slide sleeve 510, causing the slide sleeve 510 to reciprocate along the slide steel shaft 59. A reciprocating sliding soft rubber 512 is fixed inside the slide sleeve 510. The reciprocating sliding soft rubber 512 is made of a soft elastic material, fixed inside the slide sleeve 510, moves in synchronization with the reciprocating motion of the slide sleeve 510, and directly contacts the object to be contacted, providing expansion and contraction stimulation.The second secondary gear 54 meshes with the first secondary gear 53, and the second secondary gear 54 also meshes with the eccentric gear 56 to accurately transmit power. The rear side of the washer 57 is rotatably connected to the rear inner wall of the gearbox housing 51 for the reciprocating sliding mechanism, and the outside of the first cylinder 58 contacts the inside of the annular groove frame 511.

[0015] The outer wall of the second cylinder 64 contacts the outside of the limit frame 68, and the outside of the limit rod 69 is slidably connected along the inside of the first swing arm unit 66. The outside of the vibration motor 610 contacts the inside of the engaging soft rubber 612, and the outside of the first swing arm unit 66 also contacts the inside of the engaging soft rubber 612. The outside of the limit frame 68 is slidably connected inside the box body 61, and the outside of the annular pedestal 611 is fixedly connected to the bottom inner wall of the two outer housings 2. As shown in FIG. 8, the engaging vibration mechanism 6 also includes a main housing 614. The bottom of the main housing 614 is fixedly connected to the bottom inner wall of the two outer housings 2, and a second geared motor 615 is installed inside the main housing 614. An eccentric transmission wheel 616 is fixedly connected to the driving end of the second geared motor 615. Two limit shafts 617 are fixed inside the main housing 614, a support frame 618 is slidably connected, and two rotating shafts 619 are rotatably connected. A second swing arm unit 621 is swingably connected to the outside of the rotating shaft 619, a slide rod 620 is installed inside the second swing arm unit 621, and the outside of the slide rod 620 is rotatably connected inside the support frame 618. The inside of the support frame 618 is slidable along the outside of the two limit shafts 617. The outside of the eccentric transmission wheel 616 contacts the inner wall of the support frame 618. The rotating shaft 619 acts such that the second swing arm unit 621 performs an opening and closing operation in synchronization with the forward and backward movement, and the size of the opening changes according to the angle of the second swing arm unit 621.

[0016] Operating principle: When the 130-type motor 52 in the motion mechanism 5 is started, the rotation of the motor rotates the eccentric gear 56 via the gear transmission, causing the first disc 55 to rotate synchronously. The first cylinder 58 on the first disc 55 performs circular motion, continuously applying a periodic thrust to the annular groove frame 511. As a result, the slide sleeve 510 performs stable reciprocating linear motion along the slide steel shaft 59, and the reciprocating sliding soft rubber 512 inside the slide sleeve 510 also moves synchronously, realizing expansion and contraction movements of different strokes and simulating dynamic depth changes. In the occlusal vibration mechanism 6, the first geared motor 62 provides driving force, rotating the second disc 63. The second cylinder 64 on the second disc 63 rotates, causing the limit frame 68 to slide along the support column 67. The limit rods 69 on both sides of the limit frame 68 are fitted into grooves in the left and right first oscillating arm units 66. As the limit frame 68 slides, the first oscillating arm units 66 perform a reciprocating opening and closing motion around the fixed shaft 65. The first oscillating arm units 66 and the vibration motor 610 press and release the occlusal soft rubber 612 on the outside of the annular base 611, causing a change in shape in the occlusal soft rubber 612 to achieve gripping and improve the degree of contact between the mechanism and the object it is in contact with. In the operation button mechanism 4, the silicone button 41 functions as an operation interface and triggers an internal circuit signal when pressed. This signal is transmitted to the control units of the motion mechanism 5 and the occlusal vibration mechanism 6, which adjust the rotation speed and direction of the 130 motor 52 and the first geared motor 62. By changing the motor parameters, the expansion and contraction frequency and width of the reciprocating sliding soft rubber 512, and the clamping force and rhythm of the occlusal soft rubber 612 can be precisely controlled. The button light-shielding cover 43 reduces interference from external light and ensures the stability of command input.

[0017] In another embodiment, in the occlusal vibration mechanism 6, the second geared motor 615 supplies a driving force to rotate the eccentric transmission wheel 616. The eccentric transmission wheel 616 slides the support frame 618 along the limit shaft 617. The slide rods 620 on both sides of the limit shaft 617 are fitted into the grooves of the left and right second swing arm units 621. When the support frame 618 slides, the left and right second swing arm units 621 perform reciprocating swing motions of opening and closing around the slide rods 620. The second swing arm unit 621 and the vibration motor 610 press and release the occlusal soft rubber 612 outside the annular pedestal 611, causing a shape change in the occlusal soft rubber 612 to achieve clamping. The second geared motor 615 drives the eccentric transmission wheel 616, and the eccentric transmission wheel 616 drives the left and right two second swing arm units 621 through the slide block. The second swing arm unit 621 performs synchronous opening and closing operations under the action of the rotating shaft 619 during the forward and backward movement, and the opening size changes according to the angle of the second swing arm unit 621.

[0018] Although the embodiments of the present invention have been illustrated and described, those skilled in the art will understand that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of the present invention. The scope of the present invention shall be defined by the appended claims and their equivalents.
