Description

Technical Field

[0001] The invention belongs to the technical field of adult products, and particularly relates to an artificial muscle imitation device. Background Art

[0002] Artificial muscles drive elastic materials to deform through a power source to achieve the functions of output, work and deformation displacement. In recent years, due to the separation of sexual behavior and reproduction, artificial muscles have developed rapidly as adult products. At present, the market has put forward more and more humanistic requirements for artificial muscles, mainly reflected in noise and heat problems, for example: the noise level at 0.3 meters must be lower than 50 decibels; the outer surface temperature cannot be higher than 45°C when working continuously for 30 minutes. Since the motor drive converts the rotary output into linear motion, the transmission chain is too long, so the energy loss is large and the heat is serious, which cannot meet the temperature requirements. Based on this, although the electromagnetic drive method avoids the heating problem caused by the long transmission chain, the existing electromagnetic drive has the problem of balancing the reverse electromagnetic force. In the process of balancing the reverse electromagnetic force, the rigid impact will cause noise problems, which cannot meet the humanistic requirements of the market. Summary of the invention

[0003] The main purpose of the present invention is to provide an artificial muscle device, which reduces energy consumption, solves noise and heating problems, and meets the humanistic requirements of the market.

[0012] Optionally, the elastic member includes an elastic rope, both ends of which are respectively connected to two sides of the shell that are arranged opposite to each other, and the end of the moving iron core away from the fixed iron core abuts against the elastic rope. When the power is off, the stretched rubber sleeve retracts and resets by pushing and pulling the elastic rope through the moving iron core.

[0013] Optionally, the moving iron core includes a head, a reducing section and a rod, the head and the rod are connected via the reducing section, a guide groove is formed on the fixed iron core, and the moving iron core can be movably inserted into the fixed iron core through the cooperation of the reducing section and the guide groove.

[0016] Optionally, a support block is provided in the rubber sleeve, the support block is attached to the inner wall of the rubber sleeve, and the end of the iron core passing through the inductor coil is detachably connected to the support block, so that under the action of the electromagnetic field, the iron core drives the support block to act on the rubber sleeve.

[0017] In the technical solution of the present invention, when the power is turned on, the inductor generates an electromagnetic field, and the magnetized iron core generates an electromagnetic force that pushes the inner wall of the rubber sleeve to move under the action of the electromagnetic field, and the rubber sleeve is stretched by the electromagnetic force of the iron core; when the power is turned off, the iron core cannot be magnetized, and the iron core loses its force on the rubber sleeve, so that the stretched rubber sleeve reacts to the iron core and shrinks and resets.

[0025] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0026] It should be noted that all directional indications in the embodiments of the present invention (such as up, down, left, right, front, back, etc.) are only used to explain the relative position relationship, movement status, etc. between the components under a certain specific posture (as shown in the accompanying drawings). If the specific posture changes, the directional indication will also change accordingly.

[0027] See also Figures 1 to 4 As shown, in one embodiment of the present invention, an artificial muscle device includes: a rubber sleeve 100, which is elastic and can be stretched and retracted along its depth direction; an inductor 200, which is arranged in the rubber sleeve 100, extends along the depth direction of the rubber sleeve 100, and is used to generate an electromagnetic field when powered on; an iron core 300, which can movably penetrate the inductor 200 and has a first state and a second state. When the iron core 300 is in the first state, the iron core 300 pushes the inner wall of the rubber sleeve 100 under the action of the electromagnetic field to stretch the rubber sleeve 100; when the iron core 300 is in the second state, the rubber sleeve 100 stretched when the power is off reacts to the iron core 300 and retracts and resets.

[0028] In the technical solution of the present invention, when the core 300 is in the first state, see Figure 2 As shown, when the inductor 200 is powered on, an electromagnetic field is generated, and the magnetized iron core 300 generates an electromagnetic force that pushes the inner wall of the rubber sleeve 100 to move under the action of the electromagnetic field. The rubber sleeve 100 is stretched by the electromagnetic force of the iron core 300. When the iron core 300 is in the second state, see Figure 3 As shown, when the power is off, the iron core 300 cannot be magnetized, and the iron core 300 loses the force acting on the rubber sleeve 100, so that the stretched rubber sleeve 100 reacts to the iron core 300 and retracts to reset. In this way, the reciprocating telescopic motion of the rubber sleeve 100 is achieved by alternating power on and off, thereby reducing energy loss and avoiding the problem of heating. The present invention realizes the telescopic motion of the rubber sleeve 100 through the coordination of electromagnetic drive and elastic deformation, avoiding the noise problem caused by rigid impact. Moreover, in the present invention, the output of the iron core 300 directly acts on the rubber sleeve 100 to realize the telescopic motion of the rubber sleeve 100, and there is no problem of self-consumption of output. While reducing energy consumption, the present invention solves the noise problem and the heating problem, meeting the humanistic requirements of the market.

[0029] It should be noted that the electromagnetic force and the elastic force in the present invention are both in the depth direction of the rubber sleeve 100, and no component force in other directions is generated, thereby saving energy consumption and avoiding the heating problem caused by heat loss. The artificial muscle device of the present invention also includes a control circuit, which is connected to the inductor 200 and is used to control the on and off of the inductor 200. Of course, the control circuit can also adjust the current of the inductor 200 to adjust the amplitude and frequency of the reciprocating motion of the iron core 300 through which the inductor 200 is installed. In the embodiment of the present invention, the inductor 200 includes a copper core 230 and a coil 210. The copper core 230 has a tubular structure. The coil 210 is wound around the copper core 230 along the circumference of the tubular structure. When powered on, an electromagnetic field is generated in the inductor 200. The iron core 300 is an electromagnet with magnetism when powered on. When powered on and magnetized, the iron core 300 is cut by the electromagnetic field to cut the magnetic flux lines. In order to adjust the movement direction of the iron core 300, the winding direction of the coil 210 can be adjusted to adjust the current direction, so that the iron core 300 pushes the inner wall of the rubber sleeve 100 when it moves, so that the rubber sleeve 100 stretches. Of course, the iron core 300 can be directly connected to the inner wall of the rubber sleeve 100, or it can indirectly act on the inner wall of the rubber sleeve 100 through a driving rod. This embodiment is not limited thereto, and all of the above are within the protection scope of the present invention. The rubber sleeve 100 of the embodiment of the present invention has a columnar structure. The rubber sleeve 100 is an integrally formed structural member without groove connection and auxiliary structure. While having waterproof performance, it is convenient for self-cleaning and easy to clean, which is beneficial to the cleaning and disinfection of the rubber sleeve 100.

[0030] See also Figures 1 to 4 As shown, in one embodiment of the present invention, an elastic member 500 is installed in the rubber sleeve 100. The elastic member 500 is arranged at the end of the iron core 300 away from the inductor 200, so that the rubber sleeve 100 stretched when the power is off can be retracted and reset through the iron core 300 acting on the elastic member 500. It should be noted that the elastic member 500 in the embodiment of the present invention can be a spring or an elastic rope. The rubber sleeve 100 stretched when the power is off can act on the elastic member 500 through the iron core 300. During the energy transfer process, the elastic member 500 generates a reaction force to resist the inertia force of the iron core 300, so that the elastic member 500 stores the elastic potential energy released by the rubber sleeve 100. Finally, the rubber sleeve 100 retracts and resets to a relaxed state after releasing the elastic potential energy. When the elastic member 500 balances the inertia force of the iron core 300, the deformation of the elastic rope is the largest, and the reverse displacement of the iron core 300 is the largest, as shown in FIG. Figure 4 As shown, at this time, the iron core 300 is powered on and magnetized to enter the next cycle of impact stretching. The embodiment of the present invention utilizes the deformation of the elastic member 500 to absorb the inertial force of the iron core 300, thereby avoiding rigid impact and further avoiding the generation of noise.

[0031] See also Figures 1 to 4As shown, in one embodiment of the present invention, the iron core 300 includes a fixed iron core 310 and a moving iron core 330, the fixed iron core 310 is installed on the inductor 200, the moving iron core 330 can be movably arranged through the inductor 200 and the fixed iron core 310, and an elastic member 500 is provided at the end of the moving iron core 330 away from the fixed iron core 310. It should be noted that when the embodiment of the present invention is powered on, the moving iron core 330 is magnetized by the electromagnetic field formed by the inductor magnetic field and moves toward the fixed magnet, thereby pushing the inner wall of the rubber sleeve 100 and stretching the rubber sleeve 100. At the same time, the fixed iron core 310 is powered on and magnetized, and the electromagnetic force that attracts the moving iron core 330 is generated due to the limited position, thereby increasing the acceleration of the moving iron core 330, thereby accelerating the movement of the moving magnet. In addition, the accelerated movement of the moving iron core 330 will promote the electromagnetic field of the inductor 200 to generate a larger electromagnetic force, further promoting the accelerated movement of the moving iron core 330, and the moving iron core 330 generates a larger acceleration and a faster movement rate. In this way, multi-stage acceleration of the moving iron core 330 is achieved, and the variable acceleration movement of the moving iron core 330 is achieved through the multi-stage acceleration of the moving iron core 330, avoiding a single mechanical movement and meeting the humanistic requirements of the market. In the embodiment of the present invention, the rubber sleeve 100 stretched inside can act on the elastic member 500 through the moving iron core 330 when the power is off, and the elastic member 500 generates a reaction force to resist the inertia force of the moving iron core 330, so that the elastic member 500 stores the elastic potential energy released by the rubber sleeve 100, avoiding rigid impact, thereby reducing the noise generated. Supplementary explanation, in the embodiment of the present invention, the end of the moving iron core 330 can be detachably connected to the inner wall of the rubber sleeve 100 through the driving rod, and the connection between the moving iron core 330 and the driving rod can be a threaded connection, an interference fit connection, a slot connection, a fixed connection such as welding, or even an integrally formed structure, and the embodiment of the present invention is not limited thereto, and the above are all within the protection scope of the present invention.

[0032] See also Figures 1 to 4 As shown, in one embodiment of the present invention, the fixed iron core 310 includes a plug-in portion 311 and a cover portion 313, the plug-in portion 311 is convexly arranged on the surface of the cover portion 313, the plug-in portion 311 is inserted into the inductor 200, and the cover portion 313 is convexly arranged on the inductor 200. It should be noted that in the embodiment of the present invention, the fixed iron core 310 is stably installed on the inductor 200 through the cooperation of the plug-in portion 311 and the cover portion 313, which is conducive to accelerating the movement of the moving iron core 330 through the magnetization of the fixed iron core 310, while improving the structural stability and avoiding the generation of noise. In addition, through the setting of the cover portion 313, a closed structure is formed, thereby effectively reducing the propagation of noise.

[0033] See also Figures 1 to 4As shown, in one embodiment of the present invention, a housing 400 is installed in the rubber sleeve 100, the housing 400 and the cover portion 313 enclose a closed cavity 400a, the inductor 200 is arranged in the closed cavity 400a, the moving iron core 330 passes through the closed cavity 400a, and the elastic member 500 is arranged on the surface of the housing 400 away from the fixed iron core 310. It should be noted that in the embodiment of the present invention, the inductor 200 is installed in the closed cavity 400a formed by the housing 400 and the cover portion, the rubber sleeve 100 is sleeved on the housing 400, and the elastic member 500 is arranged on the surface of the housing 400 away from the fixed iron core 310, while ensuring the stability of the structural installation during the driving process, effectively avoiding the propagation of noise, and effectively reducing the working noise of the artificial muscle device. Of course, a silencing structure can also be arranged inside the housing 400, and the noise generated by the silencing structure is reduced, thereby reducing the working noise and meeting the provisions of the noise requirements.

[0034] See also Figures 1 to 4 As shown, in one embodiment of the present invention, the elastic member 500 includes an elastic rope, both ends of which are respectively connected to two sides of the shell 400 that are arranged back to back, and the end of the moving iron core 330 away from the fixed iron core 310 abuts against the elastic rope. When the power is off, the stretched rubber sleeve 100 retracts and resets by pushing and pulling the elastic rope through the moving iron core 330. It should be noted that, in the embodiment of the present invention, the elastic rope is in a slightly stretched state before power is turned on, and the rubber sleeve 100 is in a relaxed state. When power is turned on, the moving iron core 330 is magnetized by the elastic rope and is affected by the electromagnetic field to impact the rubber sleeve 100. The rubber sleeve 100 is impacted by the moving iron core 330 and stores elastic potential energy. Since the rubber sleeve 100 has high elasticity, the noise generated during the impact process is small. When power is turned off, the moving iron core 330 loses its magnetism and does not generate any force on the rubber sleeve 100. The stretched rubber sleeve 100 releases its elastic potential energy and reacts to the moving iron core 330. The moving iron core 330 moves in the opposite direction at a very high speed. The deformation internal force of the elastic rope is used to effectively absorb the inertia force of the moving iron core 330, thereby avoiding the moving iron core 330 from impacting the support seat 600 when it moves in the opposite direction, thereby reducing the noise generated and meeting the noise requirements. In addition, in the embodiment of the present invention, the elastic member 500 may include multiple elastic ropes, both ends of each elastic rope are connected to the two ends of the shell 400 that are arranged opposite to each other, and the end of the moving iron core 330 away from the fixed iron core 310 simultaneously contacts the multiple elastic ropes, so that when the power is cut off, the stretched rubber sleeve 100 is pushed and pulled by the moving iron core 330 to retract and reset, and the multiple elastic ropes are used to fully absorb the inertia force of the moving iron core 330, thereby avoiding rigid impact and further reducing noise.

It should be noted that, in the embodiment of the present invention, the head 331 is sandwiched between the inner walls of the inductor 200, the cross-sectional area of ​​the head 331 is larger than the cross-sectional area of ​​the rod 335, and the head 331 is connected to the rod 335 through the diameter reducing end, so that the rod 335 passes through the fixed iron core 310. Under the cooperation of the reducing section 333 and the guide groove 311a, the reducing section 333 of the moving iron core 330 moves toward the guide groove 311a of the fixed iron core 310, and guides the moving iron core 330 to the fixed iron core 310. When the moving iron core 330 moves relative to the fixed iron core 310, a changing magnetic field is generated, and the moving iron core 330 is driven by the changing magnetic field to achieve the variable speed movement of the rubber sleeve 100. In addition, the reducing section 333 can be a conical reducing structure, a step reducing structure, or a combination of multiple reducing structures, as long as it can achieve the guiding cooperation with the fixed iron core 310, and the embodiments of the present invention are not limited thereto, and the above are all within the protection scope of the present invention.

It should be noted that the moving iron core 330 of the embodiment of the present invention can movably penetrate the fixed iron core 310 through the cooperation of the shock absorbing pad 700 and the escape opening 311b, while achieving the guided movement of the moving iron core 330, reducing the rigid impact of the moving iron core 330 on the fixed iron core 310, and reducing the noise generated.

Supplementary explanation: The surface of the support seat 600 facing away from the elastic member 500 is provided with a wire hole, and the wire connected to the inductor 200 is connected to the outside through the wire hole.
