Description

Technical Field

[0001] This invention belongs to the field of toy interaction technology, and specifically relates to a plush toy interaction system based on dielectric gel and a plush toy. Background Technology

[0002] Intelligent interactive plush toys can perform various actions and interact with people through touch, sound, and other means, but they have also exposed many problems:

[0003] First, the hard and complex motors inside the smart interactive plush toys currently on the market make the plush toys hard and prone to electric leakage and other dangers when in contact with users, resulting in low safety.

[0004] Second, the noise and vibration generated by the motor-driven plush toy during operation can affect the implementation of the interactive process.

[0005] Third, because the traditional motor-driven structure of plush toys is relatively large, it is difficult to complete more detailed movements such as simulating the twitching of animal ear tips. Summary of the Invention

[0006] The purpose of this invention is to provide an interactive system for plush toys based on dielectric gel and plush toys in order to solve the above-mentioned problems.

[0007] To achieve the above objectives, the present invention adopts the following technical solution:

Each module is independently located in the corresponding position on the plush toy. The ear control module, head control module, arm control module, hand control module, and tail control module all contain dielectric gel to control the movement of the corresponding position on the plush toy.

[0009] Furthermore, the ear control module includes a dielectric gel strip, electrode plates, a voice-activated switch, a battery, and a plastic frame; the plastic frame serves as the ear of the plush toy, the dielectric gel strip is located inside the plastic frame, and electrode plates are respectively located at both ends of the dielectric gel strip, with the electrode plates respectively connected to the positive and negative terminals of the battery; the voice-activated switch is located between the electrode plates and the positive terminal of the battery.

[0010] Furthermore, the voice-activated switch includes a microphone element and a delay relay, which are connected in series to form the voice-activated switch; a silicone sealant is provided on the outside of the plastic frame.

[0011] Furthermore, the head control module includes a nodding module, a clockwise rotation module, a counterclockwise rotation module, a sound sensor, a head power supply, and a dielectric gel. The clockwise and counterclockwise rotation modules are stacked on top of each other, with the nodding module positioned on top of the counterclockwise rotation module. Each of the clockwise, counterclockwise, and nodding modules contains a dielectric gel plate. The dielectric gel plate and the sound sensor are connected to the head power supply.

[0012] Furthermore, the nodding module, clockwise rotation module, and counterclockwise rotation module are all made of rubber; the dielectric gel plates inside the clockwise and counterclockwise rotation modules are arranged along the diagonal direction; and rigid rods are provided on the inner edges of the clockwise and counterclockwise rotation modules.

[0013] Furthermore, the arm control module includes an arm control dielectric gel strip, an arm control electrode plate, a piezoresistive pressure sensor, and a battery unit. The arm control dielectric gel strip is installed inside the plush toy's arm, and arm control electrode plates are respectively installed at both ends of the arm control dielectric gel strip. The arm control electrode plates are respectively connected to the positive and negative terminals of the battery unit. A piezoresistive pressure sensor is installed between the arm control electrode plate and the positive terminal of the battery unit, and the piezoresistive pressure sensor is located at the chest of the plush toy.

[0014] Furthermore, the piezoresistive pressure sensor is connected in series with a pressure sensing switch.

[0015] Furthermore, the hand control module includes a cellular cell dielectric gel, silicone rubber cellular strips, a housing, interdigital dielectric gel, a pressure sensor, and a power controller; both the pressure sensor and the power controller are located inside the housing, with the pressure sensor located on top of the power controller; several silicone rubber cellular strips are hinged to the housing, each silicone rubber cellular strip contains a cellular cell dielectric gel, and interdigital dielectric gels are located between adjacent silicone rubber cellular strips; both the interdigital dielectric gels and the cellular cell dielectric gels are connected to the power controller.

[0016] Furthermore, the tail control module includes a tail electrode plate, a controller, a sensor, a tail power supply, rod-shaped dielectric gel, and a tail strip-shaped dielectric gel; the tail power supply is connected to the controller, the controller is connected to the sensor, and the positive and negative terminals of the controller are respectively connected to the two tail electrode plates; a rod-shaped dielectric gel is disposed between the two tail electrode plates, and the tail electrode plate connected to the negative terminal is also connected to one end of two rod-shaped dielectric gels, and the other ends of the two rod-shaped dielectric gels are connected to the tail strip-shaped dielectric gel.

[0017] Furthermore, there are plush toys based on dielectric gels, including interactive systems for plush toys based on dielectric gels.

[0018] Compared with the prior art, the present invention has the following technical effects:

[0019] Each module of this invention is set independently, so that the function of each module can be realized independently. The use of inorganic dielectric gel to drive the movement of the plush toy's ears can reduce the noise during the operation of the mechanism, thereby reducing the presence of the driving mechanism.

[0020] The advantages of the voice- and touch-based triggering modes used in this invention are: the triggering method without switch contact is more natural than traditional button control, reduces the possibility of electrical components being exposed on the outside of the plush toy, thereby reducing the risk of electric shock to the user and improving the user's experience when interacting with the toy;

[0021] This invention controls the frequency, amplitude, or pattern of the toy's tail movements based on user input signals such as touch, sound, or gestures, thereby achieving different degrees of tail lifting, lowering, opening, and closing movements, thus enhancing the interactive experience between people and toys.

[0022] This invention uses soft dielectric gel artificial muscles instead of motors to drive the movement of plush toy ears, which can reduce the volume and rigidity of the internal drive device of the toy and reduce the weight of the plush toy. Attached Figure Description

Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0035] Example 1:

[0036] The interactive system for plush toys based on dielectric gel includes an ear control module 1, a head control module 2, an arm control module 3, a hand control module 4, and a tail control module 5. Each module is independently located at the corresponding position on the plush toy. The ear control module, head control module, arm control module, hand control module, and tail control module all contain dielectric gel to control the movement of the corresponding position on the plush toy.

[0037] Dielectric gel driven plush toys can eliminate the need for traditional rigid motor actuators. All parts of the actuator can be made of flexible materials with elasticity, which can improve the toy's feel, reduce the hardness and weight of the plush toy, improve the toy's performance and quality, and at the same time ensure the toy's safety and comfort, while significantly reducing noise.

[0038] Please see Figure 1 and Figure 2 A voice-controlled plush toy ear control device includes a battery module 101, a microphone element 102, circuit wires 103, a plastic frame 105, a dielectric gel strip 106, a silicone sealant 107, a time-delay relay 108, and an electrode plate 109. Each component is connected to an electrical control circuit via wires. The positive terminal of the battery module 101 is connected to the microphone element via a wire, and then connected to the electrode plate 109 via the time-delay relay 108. The two electrode plates 109 together hold the front end of the biased dielectric gel strip 106. The plastic frame 105 is nested at the end of the dielectric gel strip 106. Controlling the plush toy's ear movements via sound eliminates the need for user contact with switches or motors, improving the safety of interactive plush toys and reducing the risk of electric shock. Simultaneously, embedding a small control drive module inside the plush toy enhances the accuracy of ear movement control.

[0039] Please see the appendix Figure 3 and Figure 4The head control module 2 includes a nodding module 201 for controlling the nodding action of the plush toy; wires 202 for controlling the movement of artificial muscles 207; rigid rods 203 for making the upper and lower planes of the clockwise rotation module 206 and the counterclockwise rotation module 207 parallel; a sound sensor 204 for collecting external information; and a head power supply 205 that receives and processes the information from the sensor 204 via the wires 202, and then sends it to the dielectric gel plate 208 to drive the movement of the nodding module 201, the clockwise rotation module 206, and the counterclockwise rotation module 207 of the plush toy. The clockwise rotation module 206 and the counterclockwise rotation module 207 are both made of flexible materials and are slightly thinner at the diagonal to facilitate folding under the drive of the artificial muscles. When the dielectric gel plate 208 receives a voltage signal, it begins to contract, thereby causing the clockwise rotation module 206 to rotate clockwise (rotation angle less than 90 degrees), or the counterclockwise rotation module 207 to rotate counterclockwise (rotation angle less than 90 degrees), or the head-nodding module 201 to bend. This is how the toy's head moves. By transmitting voltage changes to the dielectric gel, it causes deformation, which in turn drives the movement of the dielectric gels in each module. This results in head movements, making interactive actions more natural.

[0040] Please see Figure 5 , Figure 6 The arm control module 3 includes a pressure sensing switch 301, a piezoresistive pressure sensor 302, a battery unit 303, an arm control electrode plate 305, an arm control dielectric gel strip 308, and wires 310. Each component is connected to the electrical control circuit via wires. The positive terminal of the battery unit 303 is connected to the pressure sensing switch via a wire, and then connected to the piezoresistive pressure sensor 302 via the pressure sensing switch 301. Two wires are led out from the piezoresistive pressure sensor 302 to connect to the arm control electrode plate 305. The arm control electrode plate 305 is clamped at the end of the first dielectric gel strip 308, and the second anode plate 306 and the second cathode plate 307 are clamped at the end of the arm control dielectric gel strip 308. The toy detects the user's hugging motion through a built-in pressure sensor, and the degree of hugging can be changed by altering the voltage across the dielectric gel in real time, simulating a real hugging behavior. The entire circuit is encased in silicone to protect the components inside. A pressure-sensing switch is installed inside the toy's chest, which automatically turns on when the user hugs the toy and automatically turns off when the user leaves the toy, saving power while creating a natural interactive process.

[0041] Please see Figure 7The hand control module 4 includes a pressure sensor 405 and a controller 406. The pressure sensor 405 and controller 406 are installed in a housing 403. The housing 403 is connected to the silicone rubber honeycomb strip 402 via a hinge, which consists of a housing hinge 407 and a honeycomb strip hinge 408. Interdigital dielectric gel 404 is bonded between adjacent silicone rubber honeycomb strips 402. A honeycomb unit dielectric gel 401 is installed in each silicone rubber honeycomb unit of the silicone rubber honeycomb strip 402. Pressing the pressure sensor 405 generates a signal, which is transmitted to the controller 406. After processing the relevant signal, the controller 406 sends voltage to the interdigital dielectric gel 404 and the honeycomb unit dielectric gel 401, causing them to contract and thus controlling the opening and closing movement of the silicone rubber honeycomb strip. The controller transmits voltage changes to the dielectric gel, causing it to deform and thus driving the movement of the silicone rubber honeycomb strip. This achieves the opening and closing of the hand, ensuring natural movement while maintaining the softness of the toy's hand.

[0042] Please see Figure 8 The tail control module 5 includes a tail electrode plate 502, a controller 503, a sensor 504, a tail power supply 506, a rod-shaped dielectric gel 507, and a tail strip-shaped dielectric gel 509. The tail power supply 506 is connected to the controller 503, the controller 503 is connected to the sensor 504, and the positive and negative terminals of the controller 503 are respectively connected to the two tail electrode plates 502. A rod-shaped dielectric gel 507 is disposed between the two tail electrode plates 502. The tail electrode plate 502 connected to the negative terminal is also connected to one end of two rod-shaped dielectric gels 507, and the other end of the two rod-shaped dielectric gels 507 is connected to the tail strip-shaped dielectric gel 509.

[0043] The upper electrode is divided into two halves by an insulating pad, which allows for different changes in the electrical parameters of the two sides. One dielectric gel is sandwiched between and connected to the two stretchable electrodes, while the other two dielectric gels are respectively connected to the upper electrode and the tail (soft material). The sensor 504 is used to detect input signals from the user such as touch, sound, or gestures to the plush toy and transmits the input signals to the controller 503. The controller 503 applies voltages of different degrees and polarities to the actuator 502 according to the preset program and the information sensed by the sensor, thereby controlling the deformation of the rod-shaped dielectric gel 507 and the tail strip-shaped dielectric gel 509, i.e., various actions and combinations of actions such as lifting and lowering the tail, opening and closing.

[0044] Example 2:

[0045] The interactive system for plush toys based on dielectric gel includes an ear control module 1, a head control module 2, an arm control module 3, a hand control module 4, and a tail control module 5. Each module is independently located at the corresponding position on the plush toy. The ear control module, head control module, arm control module, hand control module, and tail control module all contain dielectric gel to control the movement of the corresponding position on the plush toy.

[0046] This system was installed inside a plush toy.

[0047] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, and not to limit them; although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present invention.
