Description

Technical Field

[0001] This invention relates to the field of switch technology, and in particular to a wireless auxiliary device and voice control method for switches without wiring. Background Technology

[0002] With the rapid development of the Internet of Things and smart home technologies, users have placed higher demands on the convenience and flexibility of home appliance control methods. Currently, lighting and various electrical appliances in residential spaces are mostly controlled by mechanical switches fixed to the wall. The physical location of these switches is fixed, and when it is necessary to turn an appliance on or off, one must walk to the switch location and manually press the panel button. Especially in scenarios such as bedrooms and living rooms, light switches are often only located on the wall at the entrance. When users are sleeping or in a distant location indoors, the operation of the switches is extremely inconvenient, affecting the living experience and the comfort of space use.

[0003] To overcome the aforementioned problems, some mechanical devices have emerged on the market to assist in operating existing wall switches. These devices use a built-in micro-motor to drive a lever to reciprocate, simulating the action of a human hand pressing or toggling a switch button. However, when these existing devices are operating, the motor generates continuous and significant mechanical vibration and friction noise, which is particularly noticeable at night or in quiet environments, easily causing auditory interference and affecting the user experience.

Detailed Implementation

[0019] To enable those skilled in the art to better understand the present invention, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0020] The present application will be further described in detail below with reference to the accompanying drawings.

[0021] This application discloses a wireless auxiliary device for switching without wiring, comprising: a main body 1, a control component 2, a first coil 3 and a second coil 4, and a linkage assembly 5; the main body 1 is hollow, forming an installation cavity 11; the control component 2 is disposed in the installation cavity 11; the first coil 3 and the second coil 4 are spaced apart on the control component 2; the linkage assembly 5 is rotatably disposed on the main body 1 and spaced apart from the control component 2; the linkage assembly 5 is provided with a first permanent magnet 51 and a second permanent magnet 52; the first permanent magnet 51 is disposed opposite to the first coil 3, and the second permanent magnet 52 is disposed opposite to the second coil 4; the magnetic poles of the first permanent magnet 51 and the second permanent magnet 52 are opposite; wherein, the control component 2 is used to control the generation of electromagnetic force between the first coil 3 and the first permanent magnet 51 and between the second coil 4 and the second permanent magnet 52, so as to drive the linkage assembly 5 to rotate.

[0022] Specifically, the first coil 3 and the second coil 4 are respectively spaced apart on the control component 2. The first coil 3 and the second coil 4 are spatially independent and electrically connected to the output terminal of the control component 2. The connecting rod assembly 5 is rotatably mounted on the main body 1, and a preset distance is maintained between the connecting rod assembly 5 and the control component 2. A first permanent magnet 51 and a second permanent magnet 52 are fixedly mounted on the connecting rod assembly 5, wherein the first permanent magnet 51 and the first coil 3 are spatially opposite to each other, and the second permanent magnet 52 and the second coil 4 are spatially opposite to each other. The magnetic pole directions of the first permanent magnet 51 and the second permanent magnet 52 are set to be opposite in orientation.

[0023] In actual operation, control component 2 receives external trigger signals or internal preset control logic, applying a current with controllable direction and duration to the first coil 3 and the second coil 4. Based on the principle of electromagnetic induction, the first coil 3 generates a first electromagnetic field when energized, which interacts with the inherent magnetic field of the first permanent magnet 51, forming an electromagnetic force acting on the first permanent magnet 51. Simultaneously, the second coil 4 generates a second electromagnetic field when energized, which interacts with the inherent magnetic field of the second permanent magnet 52, forming an electromagnetic force acting on the second permanent magnet 52. Since the magnetic poles of the first permanent magnet 51 and the second permanent magnet 52 are opposite in direction, and the relative positions of the coils and their corresponding permanent magnets are determined, the two electromagnetic forces create a superposition of torques in the same direction on the linkage assembly 5, thereby driving the linkage assembly 5 to rotate. The rotation of the linkage assembly 5 can be used to touch or toggle the mechanical actuator of the controlled switch, realizing the switching state. After the state switching is completed, control component 2 cuts off the excitation current of the first coil 3 and the second coil 4, the electromagnetic field disappears, and the linkage assembly 5 stops moving, awaiting the next action command.

[0024] In this embodiment, the internal space dimensions of the mounting cavity 11 are adapted to the overall outline dimensions of the linkage assembly 5. That is, a preset movement gap is maintained between the inner wall surface of the mounting cavity 11 and the outer surfaces of each component of the linkage assembly 5 at its limit position, ensuring that the linkage assembly 5 does not interfere with the inner wall of the mounting cavity 11 throughout its entire range of motion. At the same time, it is ensured that when the swing end of the second swing arm 54 reaches the end position of the pressing stroke, the end contact of the second swing arm 54 can form effective contact with the button surface of the controlled switch, and the pressing force reaches the stroke threshold required for the switch action.

[0025] In this embodiment, the main body 1 has an assembly hole 12; the connecting rod assembly 5 includes a first swing arm 53 and a second swing arm 54, and a first drive arm 55; the first swing arm 53 is disposed in the mounting cavity 11; at least a portion of the first swing arm 53 passes through the assembly hole 12 and extends outside the mounting cavity 11; the middle portion of the second swing arm 54 is connected to the end of the first swing arm 53 extending outside the mounting cavity 11. The first drive arm 55 is disposed in the mounting cavity 11; the middle portion of the first drive arm 55 is connected to the end of the first swing arm 53 opposite to the second swing arm 54; one end of the first drive arm 55 is provided with a first permanent magnet 51, and the other end is provided with a second permanent magnet 52; wherein, when the first drive arm 55 rotates, it drives the second swing arm 54 to rotate.

[0026] Specifically, the mounting hole 12 penetrates the wall of the main body 1, making the mounting cavity 11 connected to the external space of the main body 1. The connecting rod assembly 5 consists of a first swing arm 53, a second swing arm 54, and a first drive arm 55. One end of the first swing arm 53 passes through the mounting hole 12 from inside the mounting cavity 11 and extends to the outside of the mounting cavity 11. The middle region of the second swing arm 54 is connected to the end of the first swing arm 53 that extends to the outside of the mounting cavity 11.

[0027] The first drive arm 55 is disposed inside the mounting cavity 11 and is located above or to the side of the control assembly 2, maintaining a preset spatial distance from the first coil 3 and the second coil 4. The middle region of the first drive arm 55 is connected to the end of the first swing arm 53 that is away from the second swing arm 54, that is, the engagement point of the first drive arm 55 and the first swing arm 53 is located at the end of the first swing arm 53 located inside the mounting cavity 11.

[0028] A first permanent magnet 51 is fixedly disposed at the first end of the first drive arm 55, and the first permanent magnet 51 is arranged opposite to the first coil 3; a second permanent magnet 52 is fixedly disposed at the second end of the first drive arm 55, and the second permanent magnet 52 is arranged opposite to the second coil 4. The magnetic poles of the first permanent magnet 51 and the second permanent magnet 52 are set to be oriented in opposite directions.

[0029] In actual operation, the control component 2 applies current to the first coil 3 and the second coil 4, generating a first electromagnetic force between the first coil 3 and the first permanent magnet 51, and simultaneously generating a second electromagnetic force between the second coil 4 and the second permanent magnet 52. Since the magnetic poles of the first permanent magnet 51 and the second permanent magnet 52 are set in opposite directions, the first and second electromagnetic forces generate a torque in the same direction along the rotation axis of the first drive arm 55. The two forces are vector-superimposed to form a resultant torque, driving the first drive arm 55 to rotate around its pivot point. The rotation of the first drive arm 55 is transmitted to the first swing arm 53, which rotates synchronously around the mounting hole 12. The rotation of the first swing arm 53 is further transmitted to the second swing arm 54, driving it to perform a swinging motion. After the second swing arm 54 swings, its two ends alternately press the corresponding button areas of the controlled switch, realizing the mechanical operation of turning the switch on and off.

[0030] In this embodiment, the first swing arm 53 and the second swing arm 54 are integrally formed, and the shapes of the first swing arm 53 and the second swing arm 54 are "T" shaped, while the overall shape of the first drive arm 55, the first swing arm 53, and the second swing arm 54 is "H" shaped. The integral forming of the first drive arm 55, the first swing arm 53, and the second swing arm 54 ensures that there is no relative motion loss during the transmission of electromagnetic driving force from the first drive arm 55 to the second swing arm 54, thereby achieving precise transmission of displacement and torque.

[0031] In one embodiment, the linkage assembly 5 further includes a second drive arm 56, a third drive arm 57, and a fourth drive arm 58; the second drive arm 56 is disposed in the mounting cavity 11; the middle part of the second drive arm 56 is connected to the end of the first swing arm 53 opposite to the second swing arm 54; the third drive arm 57 and the fourth drive arm 58 are spaced apart on both sides of the second drive arm 56 and are both connected to the second drive arm 56; a first permanent magnet 51 is provided at one end of the third drive arm 57 opposite to the second drive arm 56; a second permanent magnet 52 is provided at one end of the fourth drive arm 58 opposite to the second drive arm 56.

[0032] Specifically, the second drive arm 56 is disposed inside the mounting cavity 11. The middle region of the second drive arm 56 is connected to the end of the first swing arm 53 that is away from the second swing arm 54. The third drive arm 57 and the fourth drive arm 58 are respectively disposed on both sides of the second drive arm 56, and are spatially spaced apart. One end of the third drive arm 57 is connected to the first end of the second drive arm 56, and one end of the fourth drive arm 58 is connected to the second end of the second drive arm 56. The ends of the third drive arm 57 and the fourth drive arm 58 that are away from the second drive arm 56 extend away from the second drive arm 56, forming a cantilevered extension structure.

[0033] A first permanent magnet 51 is fixedly mounted on the end of the third drive arm 57 opposite to the end of the second drive arm 56, and the first permanent magnet 51 is arranged opposite to the first coil 3. A second permanent magnet 52 is fixedly mounted on the end of the fourth drive arm 58 opposite to the end of the second drive arm 56, and the second permanent magnet 52 is arranged opposite to the second coil 4. The magnetic poles of the first permanent magnet 51 and the second permanent magnet 52 are oriented in opposite directions.

[0034] In actual operation, control component 2 applies current to the first coil 3 and the second coil 4. A first electromagnetic force is generated between the first coil 3 and the first permanent magnet 51, acting on the distal end of the third drive arm 57; a second electromagnetic force is generated between the second coil 4 and the second permanent magnet 52, acting on the distal end of the fourth drive arm 58. Since the magnetic poles of the first permanent magnet 51 and the second permanent magnet 52 are opposite in direction, and the third drive arm 57 and the fourth drive arm 58 are located on opposite sides of the second drive arm 56, the first and second electromagnetic forces create a superimposed torque in the same direction on the second drive arm 56, generating a resultant torque that drives the second drive arm 56 to rotate, thereby causing the second swing arm 54 to rotate. Similarly, the two ends of the second swing arm 54 alternately press the corresponding button areas of the controlled switch to realize the mechanical operation of turning the switch on and off.

[0035] In this embodiment, the third drive arm 57 and the fourth drive arm 58 can be configured to extend symmetrically relative to the second drive arm 56, with the lever arm lengths on both sides of the second drive arm 56 being equal, so that the torque generated by the first electromagnetic force and the second electromagnetic force on the second drive arm 56 is symmetrical, which facilitates the control component 2 to achieve precise torque control by adjusting the amplitude ratio of the currents of the two coils.

[0036] In this embodiment, the second drive arm 56, the third drive arm 57, and the fourth drive arm 58 are integrally formed, and the second drive arm 56, the third drive arm 57, and the fourth drive arm 58 are U-shaped. At the same time, the first swing arm 53 and the second swing arm 54, as well as the first drive arm 55, the second drive arm 56, the third drive arm 57, and the fourth drive arm 58 are integrally formed.

[0037] In one embodiment, the wireless auxiliary device for switching further includes a bearing; the outer ring of the bearing is embedded in the mounting hole 12, and the inner ring is sleeved on the first swing arm 53. Specifically, the outer ring of the bearing is fixedly embedded in the mounting hole 12, forming an interference fit with the inner wall of the mounting hole 12, so that the outer ring is kept in a fixed position relative to the main body 1 in the radial and axial directions. The inner ring of the bearing is sleeved on the outer peripheral wall of the through portion of the first swing arm 53, forming an interference fit or key connection with the first swing arm 53, so that the inner ring rotates synchronously with the first swing arm 53.

[0038] Therefore, the first swing arm 53 rotates along its axis of rotation, with the portion passing through the mounting hole 12 as its axis of rotation, through the rolling or sliding fit between the inner and outer rings of the bearing. Simultaneously, after the bearing is installed inside the mounting hole 12, its two axial ends form a limiting relationship with the end face of the mounting hole 12 and the inner wall of the mounting cavity 11, respectively, constraining the first swing arm 53's movement along its axis of rotation and ensuring that the first swing arm 53 maintains a stable axial position during rotation, without any deviation.

[0039] In one embodiment, the control component 2 includes a control circuit board, a receiving module, and a power supply; the control circuit board is disposed in the mounting cavity 11; the receiving module is disposed on the control circuit board; the receiving module is used to receive commands; the power supply is disposed in the mounting cavity 11 and electrically connected to the control circuit board. Specifically, the control circuit board includes a microcontroller and an H-bridge circuit; the microcontroller is electrically connected to the receiving module; the H-bridge circuit is connected to the first coil 3 and the second coil 4.

[0040] Specifically, the control circuit board integrates a microcontroller and an H-bridge drive circuit. The H-bridge drive circuit has a first output terminal and a second output terminal, wherein the first output terminal is electrically connected to the first coil 3, and the second output terminal is electrically connected to the second coil 4. Under the control of the pulse width modulation signal of the microcontroller, the H-bridge drive circuit can independently adjust the polarity and amplitude of the output voltage of the first and second output terminals, thereby controlling the direction and intensity of the current flowing through the first coil 3 and the second coil 4 respectively. The magnetic poles of the first permanent magnet 51 and the second permanent magnet 52 are set to opposite orientations to ensure that, under the same energizing state, the direction of the electromagnetic force generated between the first coil 3 and the first permanent magnet 51 is opposite to the direction of the electromagnetic force generated between the second coil 4 and the second permanent magnet 52, thereby forming a driving mode of repulsion and attraction, i.e., a superposition effect of push and pull torques.

[0041] After receiving the first control command sent by the external transmitter, the receiving module transmits it to the microcontroller, which generates the first drive signal and outputs it to the H-bridge drive circuit.

[0042] The first output terminal of the H-bridge drive circuit applies a first polarity voltage to the first coil 3, generating a first directional current in the first coil 3, thereby generating a first polarity electromagnetic field. This first polarity electromagnetic field has the same polarity as the inherent magnetic field of the first permanent magnet 51, creating a repulsive electromagnetic force that drives the first permanent magnet 51 and the corresponding ends of the third drive arm 57 or the first drive arm 55 connected to it away from the first coil 3. Simultaneously, the second output terminal of the H-bridge drive circuit applies a second polarity voltage, opposite to the first polarity, to the second coil 4, generating a second directional current in the second coil 4, also opposite to the first direction, thereby generating a second polarity electromagnetic field. This second polarity electromagnetic field has the opposite polarity to the inherent magnetic field of the second permanent magnet 52, creating an attractive electromagnetic force that drives the second permanent magnet 52 and the corresponding ends of the fourth drive arm 58 or the first drive arm 55 connected to it closer to the second coil 4.

[0043] Under the combined effect of the repulsive and attractive forces, the third drive arm 57 and the fourth drive arm 58 experience superimposed torques in the same direction, driving the second drive arm 56 to rotate. This, in turn, drives the second swing arm 54 to swing in the corresponding direction via the first swing arm 53, causing the first end of the second swing arm 54 to press the switch rocker, thus achieving the switch-on operation. After rotation is complete, the microcontroller maintains the output state of the H-bridge drive circuit unchanged, and the first coil 3 and the second coil 4 continuously output electromagnetic force. The interlocking electromagnetic force generated by the two coils keeps the movable bracket and the second swing arm 54 in the current pressing position, so that the first end of the second swing arm 54 continues to press the wall switch rocker until a reverse control command is received.

[0044] After receiving the second control command sent by the external transmitter, the receiving module transmits it to the microcontroller. The microcontroller generates a second drive signal and outputs it to the H-bridge drive circuit. In response to the second drive signal, the H-bridge drive circuit applies a second polarity voltage to the first coil 3 from its first output terminal, causing a current in the first coil 3 to flow in the opposite direction to the first direction, generating an electromagnetic field with the opposite polarity to the first polarity. This electromagnetic field has the opposite polarity to the inherent magnetic field of the first permanent magnet 51, and the two generate an attractive electromagnetic force, driving the first permanent magnet 51 and the corresponding ends of the third drive arm 57 or the first drive arm 55 connected to it to approach the first coil 3.

[0045] Simultaneously, the H-bridge drive circuit applies a first polarity voltage to the second coil 4 from its second output terminal, causing a current in the second coil 4 to flow in the same direction as the first direction, generating an electromagnetic field with the same polarity as the first field. This electromagnetic field has the same polarity as the inherent magnetic field of the second permanent magnet 52, and the two generate a repulsive electromagnetic force, driving the second permanent magnet 52 and the corresponding ends of the fourth drive arm 58 or the first drive arm 55 connected to it away from the second coil 4.

[0046] Under the combined effect of attraction and repulsion, the third drive arm 57 and the fourth drive arm 58 experience a superimposed torque opposite to that in the first control command state, driving the second drive arm 56 to rotate around its rotation axis in the direction of the first coil 3. This, in turn, causes the first swing arm 53 to drive the second swing arm 54 to swing in the opposite direction, pressing the second end of the second swing arm 54 against the rocker switch, thus disconnecting the switch. After rotation, the microcontroller maintains the output state of the H-bridge drive circuit unchanged, using the interlocking electromagnetic force of the dual coils to hold the movable bracket and the second swing arm 54 in the current pressing position, ensuring that the second end of the second swing arm 54 continuously presses against the wall switch rocker until a new reverse control command is received. In this embodiment, a battery provides power to the microcontroller, the receiving module, and the H-bridge drive circuit. The working principle of the control circuit board in this embodiment is the same as in the prior art and will not be described in detail here.

[0047] In this embodiment, the transmitting end for transmitting commands is set independently of the main body 1 of the device, and establishes bidirectional or unidirectional data interaction with the built-in receiving module of the device through a wireless communication link. Specific implementations of the transmitting end include, but are not limited to, any of the following: a voice control terminal, a remote control, and a mobile phone terminal. The voice control terminal integrates a voice acquisition unit, a voice recognition engine, and a radio frequency transmission unit. The remote control is equipped with a button input unit, an encoding and modulation unit, and an infrared or radio frequency transmission unit. The mobile phone terminal has a built-in Bluetooth communication module and an application control interface. The control commands generated by each of the above transmitting ends adopt existing communication protocols at the signal encoding level, including but not limited to Bluetooth Low Energy protocol, infrared remote control protocol, or 2.4GHz proprietary radio frequency protocol. The built-in receiving module of the device is correspondingly equipped with a compatible demodulation and decoding unit, used to receive and restore the control command encoding sent by each transmitting end, recover the first control command representing a switch-on operation or the second control command representing a switch-off operation, and transmit the command in digital level form to the microcontroller to trigger the subsequent electromagnetic drive execution process.

[0048] Based on the above transmitter configuration, users can send control commands to the device through various interactive methods such as voice, remote control buttons or mobile phone touch control. The specific control principles of various transmitters are already covered by existing technologies. The device only needs to preset the decoding logic that matches the encoding format of each transmitter in its receiving module and microcontroller firmware to be compatible with multiple transmitter terminals and realize flexible and controlled operation of the wireless auxiliary device without wiring.

[0049] In one embodiment, a fixing layer is provided on the side surface of the main body 1; the fixing layer is used to detachably attach the main body 1 to a preset position. Specifically, the fixing layer forms a continuous or spaced attachment interface on the outside of the main body 1, which is used to detachably attach the main body 1 to the preset installation position, so that the device maintains a fixed relative position with the bearing surface during use, and can be removed from the bearing surface when maintenance or replacement is required.

[0050] The fixing layer uses a double-sided adhesive layer. During installation, after removing the release film, the second adhesive surface is pressed against the smooth wall surface or switch panel surface next to the wall switch. The adhesion of the pressure-sensitive adhesive achieves a fixed connection between the device and the supporting surface. Alternatively, the fixing layer uses a magnetic patch structure. This magnetic patch is embedded in a pre-set groove on the side surface of the main body 1, with its outer surface flush with or slightly lower than the side surface of the main body 1. The magnetic patch is made of neodymium magnet material, which has high magnetic energy product and anti-demagnetization properties. During installation, a ferromagnetic suction plate or iron-containing metal sheet needs to be pre-fixed at the corresponding position next to the wall switch. The magnetic patch of the main body 1 and the ferromagnetic suction plate are then attracted to each other, using magnetic attraction to achieve a detachable and fixed connection between the device and the supporting surface.

[0051] The present invention discloses a wireless auxiliary device for switching without wiring. The electromagnetic force generated by the first coil 3 and the second coil 4 in the working state directly acts on the first permanent magnet 51 and the second permanent magnet 52. Moreover, the drive link does not contain transmission components such as motors or gears that generate periodic mechanical impact or meshing noise, thus reducing the operating noise of the device. At the same time, the main body 1 adopts an engineering plastic or lightweight aluminum alloy thin-walled molding structure, the control component 2 adopts highly integrated surface-mount packaged electronic components, the first coil 3 and the second coil 4 are hollow skeletons or wound with lightweight magnetic materials, and the connecting rod assembly 5 adopts a thin-walled metal stamping part or a fiber-reinforced plastic injection molded part. The overall weight of each functional component is reduced while meeting the requirements of mechanical strength and electromagnetic performance.

[0052] Based on the aforementioned low noise and lightweight characteristics, the adhesive or magnetic fixing force provided by the fixing layer is sufficient to overcome the device's own weight and the inertial and reaction forces generated during operation, enabling the device to stably fit the preset installation position during long-term service life without creeping, shifting, or falling off.

[0053] Based on the above embodiments, the present invention also discloses a voice control method for a wireless auxiliary device for a switch, used in any of the above-described wireless auxiliary devices for switches, such as... Figure 5 and Figure 6 As shown, the steps include: S1. Obtain voice control commands and output them to the control component; S2. The control component determines the type of the voice control command and controls the first coil and / or the second coil to generate the target magnetic field according to the type.

[0054] Specifically, the step of the control component determining the type of the voice control command and controlling the first coil and / or the second coil to generate the target magnetic field according to the type includes: S21. When the first control command is recognized, the first coil generates an electromagnetic field that repels the first permanent magnet, while the second coil generates an electromagnetic field that attracts the second permanent magnet, so as to drive the linkage assembly to rotate in the first direction to a preset position. S22. When the second control command is recognized, the first coil generates an electromagnetic field that attracts the first permanent magnet, while the second coil generates an electromagnetic field that repels the second permanent magnet, so as to drive the linkage assembly to rotate to a preset position in a second direction opposite to the second direction; wherein the first direction and the second direction are opposite.

[0055] In use, the voice collection module collects voice control commands and sends them to the control component. The control component determines the type of the voice control command and controls the first coil and / or the second coil to generate the target magnetic field according to the type.

[0056] Specifically, if the current control command is determined to be the first control command, the microcontroller generates a first drive logic signal and outputs it to the H-bridge drive circuit. Responding to the first drive logic signal, the H-bridge drive circuit applies a first polarity voltage to the first coil from its first output terminal, and simultaneously applies a second polarity voltage (opposite to the first polarity) to the second coil from its second output terminal. Under the action of the first polarity voltage, the first coil generates a current in the first direction, thereby generating a first polarity electromagnetic field. This first polarity electromagnetic field has the same polarity as the inherent magnetic field of the first permanent magnet, resulting in a repulsive electromagnetic force between them. Under the action of the second polarity voltage, the second coil generates a current in the opposite direction to the first direction, thereby generating a second polarity electromagnetic field (opposite to the first polarity). This second polarity electromagnetic field has the opposite polarity to the inherent magnetic field of the second permanent magnet, resulting in an attractive electromagnetic force between them. Under the combined action of the repulsive and attractive forces, the first drive arm or drive arm assembly experiences a superimposed torque in the same direction, driving the linkage assembly to move in the first direction. The linkage assembly rotates to press the button area of ​​the external switch, executing the switch-on operation.

[0057] If the current control command is determined to be the second control command, the microcontroller generates a second drive logic signal and outputs it to the H-bridge drive circuit. Responding to the second drive logic signal, the H-bridge drive circuit applies a second polarity voltage to the first coil from its first output terminal and a first polarity voltage to the second coil from its second output terminal. Under the action of the second polarity voltage, the first coil generates a current in the opposite direction to the first direction, generating an electromagnetic field with the opposite polarity to the first polarity. This electromagnetic field has the opposite polarity to the inherent magnetic field of the first permanent magnet, resulting in an attractive electromagnetic force between them. Under the action of the first polarity voltage, the second coil generates a current in the same direction as the first direction, generating an electromagnetic field with the same polarity as the first polarity. This electromagnetic field has the same polarity as the inherent magnetic field of the second permanent magnet, resulting in a repulsive electromagnetic force between them. Under the combined action of the attractive and repulsive forces, the linkage assembly rotates to press the button area of ​​the external switch, performing a switch-off operation.

[0058] During the execution of the first or second control command, after the microcontroller drives the linkage assembly to the target position, it maintains the output state of the H-bridge drive circuit unchanged. The first and second coils remain energized, continuously generating an interlocking electromagnetic force. This interlocking electromagnetic force holds the linkage assembly in its current operating position, ensuring that the corresponding operating terminal of the linkage assembly continuously acts on the controlled switch until the microcontroller receives a reverse control command. When the microcontroller receives a new control command, it repeats the above process, controlling the linkage assembly to perform reverse movement, thereby achieving another switch state transition.

[0059] In one implementation, the voice receiving module has a pre-installed command vocabulary library. The library contains a first set of command words corresponding to switch-on operations and a second set of command words corresponding to switch-off operations. The first set of command words includes at least the following command words: turn on light, turn on, turn on switch, and open; the second set of command words includes at least the following command words: turn off light, turn off, turn off switch, and turn off. After receiving a voice signal, the voice receiving module matches the extracted voice feature vector with each entry in the command vocabulary library to determine the type of the current voice command.

[0060] The aforementioned command vocabulary library supports user-defined input. The speech recognition chip is equipped with a command input mode. In this mode, the chip receives the voice signal of the target command word repeatedly emitted by the user, samples and extracts features from this voice signal multiple times, and generates a standard feature template corresponding to the target command word after clustering and averaging. This standard feature template is then stored in the command vocabulary library as a new comparison entry. User-defined input commands are automatically associated with the corresponding command type; that is, users can input one or more custom commands for both connection and disconnection operations to suit their personalized speech habits and different dialect accents.

[0061] In this embodiment, the voice receiving module further includes a voice feedback module, which is electrically connected to the microcontroller. After executing a voice control operation, the microcontroller sends a corresponding feedback trigger signal to the voice feedback module according to the type of control command executed, such as, but not limited to, a custom prompt tone indicating that the light is on or off.

[0062] In summary, this invention discloses a wireless auxiliary device and voice control method for switches without wiring. The wireless auxiliary device for switches without wiring includes: a main body, a control component, a first coil and a second coil, and a linkage assembly. The main body has an installation cavity. The control component is disposed in the installation cavity. The first coil and the second coil are disposed on the control component. The linkage assembly has a first permanent magnet and a second permanent magnet. The first permanent magnet is disposed opposite to the first coil, and the second permanent magnet is disposed opposite to the second coil. The magnetic poles of the first permanent magnet and the second permanent magnet are opposite. In use, after receiving a control command, the control component controls the generation of electromagnetic force between the first coil and the first permanent magnet, and between the second coil and the second permanent magnet, to drive the linkage assembly to rotate, thereby actuating an external mechanical switch to achieve the on / off state of electrical appliances. This device replaces traditional motor transmission with electromagnetic drive, eliminating gear meshing noise and solving the problem of high operating noise in existing devices.
