[0024] During the operation phase, the swing direction and amplitude of the swingable component are determined according to the swing position signal; an adjustment signal is output to the second drive circuit according to the swing direction of the swingable component; and the polarity of the drive voltage is determined according to the amplitude of the swingable component, and a second polarity reversal signal is output to the second drive circuit.

[0025] The second driving circuit is used for:

[0026] During the startup phase, the driving voltage is output to the second magnetic unit according to the driving signal, so that the swing amplitude of the swingable component reaches the target swing amplitude from the initial swing amplitude; according to the first polarity reversal signal, when the swing amplitude of the swingable component reaches the preset swing amplitude, the polarity of the driving voltage is adjusted so that the swingable component swings back and forth.

[0027] During the operation phase, the absolute value of the driving voltage is adjusted according to the adjustment signal so that the absolute value of the driving voltage is maximum when the swingable component swings to the middle position, and minimum when the swingable component swings to the first position or the second position; according to the second polarity reversal signal, when the swing amplitude of the swingable component reaches the target swing amplitude, the polarity of the driving voltage is adjusted so that the swingable component swings back and forth between the first position and the second position.

[0028] According to the present invention, a swingable device is provided, wherein the sensor includes a plurality of Hall sensors; the swingable assembly includes a seat assembly, and the Hall sensors are disposed on the support assembly; the second magnetic unit includes two electromagnetic drive coils; and the control switch includes a remote control.

[0030] The first driving circuit is electrically connected to the plurality of Hall sensors and the remote controller; the second driving circuit is electrically connected to the first driving circuit and the electromagnetic driving coil.

[0031] The present invention also provides a driving method for any of the above-mentioned swingable devices, comprising:

The absolute value of the driving voltage is adjusted according to the swing direction of the swingable component, so that the absolute value of the driving voltage is maximum when the swingable component swings to the middle position, and minimum when the swingable component swings to the first or second position. The middle position corresponds to the swingable component swinging to its minimum amplitude, and the first and second positions correspond to the swingable component swinging to the target amplitude in different swing directions. Based on the amplitude of the swingable component, when the amplitude reaches the target amplitude, the polarity of the driving voltage is adjusted so that the swingable component swings back and forth between the first and second positions.

[0036] This invention provides a swingable device and its driving method. The swingable device employs a first magnetic unit, a second magnetic unit, a sensor, a control switch, and a driving device to achieve magnetic power-driven swinging of the swingable component back and forth, which can significantly reduce vibration and noise, thereby greatly improving product performance. Simultaneously, during operation, as the swingable component swings back and forth, the driving device adjusts the absolute value and polarity of the driving voltage in a timely manner based on the swing position signal output by the sensor. This ensures that the absolute value of the driving voltage is maximum when the swingable component swings to the middle position, and minimum when the swingable component swings to the first or second position. Thus, as the swingable component swings from the first or second position towards the middle position, the absolute value of the driving voltage shows an increasing trend, which can slow down the acceleration process and avoid vibration during the swinging process. The significant vibrations during the swing process make the swinging component more stable, improving stability and thus enhancing product performance. Similarly, when the swinging component swings from the middle position to the first or second position, the absolute value of the driving voltage decreases, which slows down the deceleration process and avoids significant vibrations during the swing, making the swinging component more stable and improving stability, thus further enhancing product performance. In addition, during the startup phase, the second magnetic unit and the first magnetic unit are relatively eccentrically set, allowing the swinging component to be started solely by the magnetic attraction and / or repulsion force generated by the magnetic field of the second magnetic unit, without the need for additional thrust. This reduces user operation, lowers the difficulty of product use, and further improves product performance. Attached Figure Description

[0052] To make the objectives, technical solutions, and advantages of this invention clearer, the technical solutions of this invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this invention. All other embodiments obtained by those skilled in the art based on the embodiments of this invention without creative effort are within the scope of protection of this invention.

[0053] In the embodiments of the present invention, the use of terms such as "first" and "second" to distinguish identical or similar items with essentially the same function and effect is only for the purpose of clearly describing the technical solutions of the embodiments of the present invention, and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated.

[0054] In embodiments of the present invention, "multiple" means two or more, unless otherwise explicitly defined.

[0055] In the embodiments of the present invention, the terms "upper" and "lower" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limiting the present invention.

[0056] An embodiment of the present invention provides a swingable device, see reference. Figure 1 As shown, it includes: a support assembly 1, a swingable assembly 2, a first magnetic unit 3, a second magnetic unit 4, a sensor 5, a control switch 6, and a drive device 7.

[0057] The support component and the swingable component are rotatably connected; Reference Figure 1As shown, the first magnetic unit 3 is disposed on the side of the swingable component 2 near the support component 1; the second magnetic unit 4 is disposed on the side of the support component 1 near the swingable component 2 and is offset relative to the first magnetic unit 3; Reference Figure 2 As shown, the drive unit is electrically connected to the second magnetic unit, the sensor, and the control switch, respectively. It should be noted that... Figure 1 The structure of the swinging device is shown only schematically.

[0058] The specific structures of the aforementioned support components and swingable components are not limited and can be selected according to actual needs. For example, the aforementioned swingable device can be a rocking chair, the support components can include a support base, and the swingable components can include a seat assembly. The support components and the swingable components can be rotatably connected by a rotatable linkage. Of course, other structures can also be used to achieve the rotatable connection between the support components and the swingable components; specific details can be found in relevant technologies and will not be elaborated here.

[0059] The first magnetic unit mentioned above may include permanent magnets, and the number of permanent magnets is not limited and can be selected according to design requirements. For example, if the above-mentioned swingable device is a rocking chair, the first magnetic unit may include two permanent magnets.

[0060] The aforementioned second magnetic unit may include at least one electromagnetic drive coil, which may include a magnet and a coil wound around the magnet; the number of electromagnetic drive coils is not limited and can be selected according to design requirements. For example, if the aforementioned swingable device is a rocking chair, the first magnetic unit may include two electromagnetic drive coils. When the second magnetic unit includes multiple electromagnetic drive coils, the driving voltage polarities of the different electromagnetic drive coils may be different or the same. For example, if the first magnetic unit may include two electromagnetic drive coils, the driving voltage polarities of the two electromagnetic drive coils may be different. During the swinging process, the magnetic field generated by one electromagnetic drive coil generates a magnetic attraction force on the first magnetic unit, thus exerting a pulling effect, while the magnetic field generated by the other electromagnetic drive coil generates a repulsive force on the first magnetic unit, thus exerting a pushing effect; the first magnetic unit, under the combined action of both, drives the swingable component to swing.

[0061] The aforementioned relative eccentric arrangement of the second magnetic unit and the first magnetic unit means that the second magnetic unit and the first magnetic unit are arranged opposite each other, and the center position of the second magnetic unit is offset from the center position of the first magnetic unit.

[0062] The control switch is used to output control signals to the drive unit.

[0063] The specific structure of the control switch is not limited. For example, the control switch may include a control button fixed on a support component or a swingable component, which the user can operate to output a control signal to the drive device; or, the control switch may include a remote control, which the user can operate to output a control signal to the drive device.

[0064] The sensor is used to: detect the position of the swingable component to obtain a swing position signal; and transmit the swing position signal to the drive device.

[0065] The structure of the sensor described above is not limited; for example, the sensor may include a Hall sensor.

[0066] The drive unit is used for:

[0067] During the startup phase, a driving voltage is output to the second magnetic unit according to the control signal, so that the swing amplitude of the swingable component reaches the target swing amplitude from the initial swing amplitude; according to the swing position signal, when the swing amplitude of the swingable component reaches the preset swing amplitude, the polarity of the driving voltage is adjusted so that the swingable component swings back and forth.

[0068] During operation, the swing direction and amplitude of the swingable component are determined based on the swing position signal. The absolute value of the driving voltage is adjusted according to the swing direction of the swingable component so that the absolute value of the driving voltage is the largest when the swingable component swings to the middle position, and the absolute value of the driving voltage is the smallest when the swingable component swings to the first or second position. The middle position corresponds to the swingable component swinging to the minimum amplitude, and the first and second positions correspond to the swingable component swinging to the target amplitude in different swing directions. Based on the amplitude of the swingable component, when the amplitude of the swingable component reaches the target amplitude, the polarity of the driving voltage is adjusted so that the swingable component swings back and forth between the first and second positions.

[0069] The initial swing amplitude (also known as the initial swing range) of the aforementioned oscillating component refers to the swing amplitude corresponding to the position of the oscillating component at the start-up moment, and its value can be 0°, 3°, 5°, or 10°, etc. The preset swing amplitude refers to the swing amplitude corresponding to the highest position reached during each swing of the oscillating component in the start-up phase. The preset swing amplitude corresponds to the driving voltage; if the absolute value of the driving voltage gradually increases, the corresponding preset swing amplitude will also gradually increase. The target swing amplitude (also known as the target swing range) refers to the swing amplitude that needs to be achieved under the control of the control signal.

[0070] When a driving voltage is applied, the second magnetic unit generates a magnetic field; the magnitude of the magnetic field varies depending on the driving voltage. This magnetic field exerts an attractive and / or repulsive force on the first magnetic unit, causing it to oscillate, which in turn drives the oscillating component to oscillate. The polarity of the driving voltage affects the direction of the magnetic field generated by the second magnetic unit, thus influencing the direction of the force acting on the first magnetic unit. For example, if the driving voltage is positive, the magnetic field generated by the second magnetic unit exerts an attractive force on the first magnetic unit; when the driving voltage becomes negative, the magnetic field generated by the second magnetic unit exerts a repulsive force on the first magnetic unit.

[0071] The aforementioned start-up phase refers to the phase in which the swingable component reaches the target swing amplitude from its initial swing amplitude, while the aforementioned running phase refers to the phase after the swingable component reaches the target swing amplitude.

[0072] The second magnetic unit is used to generate a magnetic field under the control of the driving voltage.

[0073] The first magnetic unit is used to move relative to the second magnetic unit when the second magnetic unit is energized, so as to drive the swingable component to swing back and forth.

[0074] The aforementioned swingable device may be a rocking chair, rocking sofa, or rocking bed, or any product or component with a swinging function, such as a game console, furniture, or medical equipment.

[0075] Embodiments of the present invention provide a swingable device. This swingable device employs a first magnetic unit, a second magnetic unit, a sensor, a control switch, and a drive device to achieve magnetically driven swinging of a swingable component back and forth. This significantly reduces vibration and noise, thereby greatly improving product performance. Simultaneously, during operation, as the swingable component swings back and forth, the drive device adjusts the absolute value and polarity of the drive voltage in real time based on the swing position signal output by the sensor. This ensures that the absolute value of the drive voltage is maximum when the swingable component swings to the middle position and minimum when it swings to the first or second position. Thus, as the swingable component swings from the first or second position towards the middle position, the absolute value of the drive voltage increases, which slows down the acceleration process and prevents vibration during swinging. Significant vibrations result in smoother oscillation of the swinging component, improving stability during oscillation and further enhancing product performance. Similarly, when the swinging component oscillates from the middle position to the first or second position, the absolute value of the driving voltage decreases, which slows down the deceleration process and prevents significant vibrations during oscillation, making the swinging component smoother and improving stability, thus further enhancing product performance. In addition, during the startup phase, the second magnetic unit and the first magnetic unit are relatively eccentrically positioned, allowing the swinging component to be started solely by the magnetic attraction and / or repulsion force generated by the magnetic field of the second magnetic unit, without the need for additional thrust. This reduces user operation, lowers the difficulty of product use, and further improves product performance.

[0076] Optionally, to facilitate users in flexibly selecting the swing amplitude of the swingable component and thereby improve the user experience, the control switch includes an on button and at least one gear button, and the control signal includes an on signal and a gear signal.

[0077] The drive device is specifically used for: in the start-up phase, starting the device according to the start-up signal; and outputting a drive voltage to the second magnetic unit according to the gear position signal, so that the swing amplitude of the swingable component reaches the target swing amplitude from the initial swing amplitude, wherein the absolute value of the drive voltage gradually increases to a preset value as the swingable component swings, and the preset value corresponds to the gear position signal.

[0078] In the control switch described above, each gear key corresponds to a driving voltage, and different driving voltages can achieve different swing amplitudes. The more gear keys there are, the more choices the user has. However, the more gear keys there are, the more difficult the design of the drive device becomes, and the greater the amount of computation required. Therefore, it is necessary to select an appropriate number of gear keys based on the actual situation.

[0079] The aforementioned control switch may include a remote control, which may be a wired remote control or a wireless remote control. The driving device may also include a buzzer, which will sound when the user presses a button on the remote control to indicate that the button was pressed successfully.

[0080] It should be noted that the above preset values ​​correspond to the gear position signal. If a gear shift is performed during use, the corresponding preset values ​​will change, and the drive device will adjust the drive voltage according to the gear position signal after the gear shift, thereby achieving the target swing amplitude after the gear shift.

[0081] The absolute value of the aforementioned driving voltage gradually increases to a preset value as the swingable component swings. The specific method of gradually increasing the voltage is not limited; for example, it can be a linear increase or a non-linear increase.

[0082] The swingable device provided in the embodiments of the present invention allows the absolute value of the driving voltage output by the driving device to gradually increase during the start-up phase. This enables the swingable component to swing slightly first, and then gradually increase the swing amplitude until the target swing amplitude is reached. This can further improve the swing stability during the start-up phase and further enhance product performance and quality.

[0083] Optionally, for ease of implementation, the drive device is specifically used to: determine the swing amplitude of the swingable component based on the swing position signal during the start-up phase; determine whether the swing amplitude of the swingable component reaches the preset swing amplitude; if so, adjust the polarity of the drive voltage so that the swingable component swings back and forth.

[0084] The method for determining the swing amplitude of the swingable component based on the swing position signal is not limited. For example, the drive device can save the correspondence between the swing position and the swing amplitude in advance, and determine the swing amplitude corresponding to the swing position signal after receiving the corresponding swing position signal.

[0085] It should be noted that during the startup phase, the absolute value of the drive voltage output by the drive device gradually increases, causing the swingable component to swing slightly at first, and then gradually increase the swing amplitude until the target swing amplitude is reached. The preset swing amplitude corresponds to the drive voltage; as the absolute value of the drive voltage gradually increases, the corresponding preset swing amplitude also gradually increases. Thus, during the startup phase, as the swingable component swings back and forth, the highest position reached by each swing amplitude also increases until the position corresponding to the target swing amplitude is reached.

[0086] To further improve the smoothness of the swing process, the drive device may optionally be used to: determine whether the swing direction of the swingable component includes the swing direction of the swingable component from the middle position to the first position or the second position during the operation phase; if so, gradually reduce the absolute value of the drive voltage.

[0087] There are no restrictions on the specific judgment method here. For example, the swing amplitude corresponding to the current position can be compared with the swing amplitude corresponding to the last detection position to determine the swing direction. If the swing amplitude corresponding to the current position is greater than the swing amplitude corresponding to the last detection position, it means that the swing direction is from the middle position to the first position or the second position.

[0088] To further improve the smoothness of the swing process, the drive device may optionally be used to: determine whether the swing direction of the swingable component includes the swing direction of the swingable component from the first position or the second position to the middle position during the operation phase; if so, gradually increase the absolute value of the drive voltage.

[0089] There are no restrictions on the specific judgment method here. For example, the swing amplitude corresponding to the current position can be compared with the swing amplitude corresponding to the last detection position to determine the swing direction. If the swing amplitude corresponding to the current position is smaller than the swing amplitude corresponding to the last detection position, it means that the swing direction is from the first position or the second position to the middle position.

[0090] In one or more embodiments, to reduce design complexity, the driving device may optionally be used to: determine whether the swing amplitude of the swingable component reaches the target swing amplitude during operation; if so, adjust the polarity of the driving voltage so that the swingable component swings back and forth between the first position and the second position.

[0091] The specific judgment method is not limited here. For example, the swing amplitude of the swingable component can be determined based on the swing position signal, and then the swing amplitude of the swingable component can be compared with the target swing amplitude. If the swing amplitude of the swingable component is the same as the target swing amplitude, or if the difference between the swing amplitude of the swingable component and the target swing amplitude is within an acceptable range, then the polarity of the drive voltage can be adjusted.

[0092] In one or more embodiments, the control switch is further configured to: output a stop signal to the driving device; the driving device is further configured to: stop outputting a driving voltage to the second magnetic unit according to the stop signal, thereby realizing the function of stopping the driving device.

[0093] In one or more embodiments, for ease of implementation and to simplify the design structure, refer to Figure 3a As shown, the driving device 7 includes a first driving circuit 71 and a second driving circuit 72; the first driving circuit 71 is electrically connected to the second driving circuit 72, the sensor 5 and the control switch 6 respectively, and the second driving circuit 72 is electrically connected to the second magnetic unit 4.

[0094] The first driving circuit is used to: determine the magnitude of the driving voltage according to the control signal during the startup phase, and output a driving signal to the second driving circuit; and determine the polarity of the driving voltage according to the swing position signal, and output a first polarity reversal signal to the second driving circuit.

[0095] During operation, the swing direction and amplitude of the swingable component are determined based on the swing position signal; an adjustment signal is output to the second drive circuit based on the swing direction of the swingable component; and the polarity of the drive voltage is determined based on the amplitude of the swingable component, and a second polarity reversal signal is output to the second drive circuit.

[0096] The second driving circuit is used to: during the startup phase, output a driving voltage to the second magnetic unit according to the driving signal so that the swing amplitude of the swingable component reaches the target swing amplitude from the initial swing amplitude; and adjust the polarity of the driving voltage according to the first polarity reversal signal when the swing amplitude of the swingable component reaches the preset swing amplitude so that the swingable component swings back and forth.

[0097] During operation, the absolute value of the driving voltage is adjusted according to the adjustment signal so that the absolute value of the driving voltage is the largest when the swingable component swings to the middle position, and the absolute value of the driving voltage is the smallest when the swingable component swings to the first position or the second position. According to the second polarity reversal signal, when the swing amplitude of the swingable component reaches the target swing amplitude, the polarity of the driving voltage is adjusted so that the swingable component swings back and forth between the first position and the second position.

[0098] The first driving circuit described above is the master driving circuit, and the second driving circuit described above is the slave driving circuit. Both can include microcontrollers, ARM (Advanced RISC Machines) chips, DSP (Digital Signal Processing) chips, or FPGA (Field Programmable Gate Array) chips, etc., without limitation. To reduce costs, microcontrollers can be used. For example, the first driving circuit may include an STC8A8K64D chip, and the second driving circuit may include an L6205 chip.

[0099] If the second magnetic unit includes two electromagnetic drive coils, then the above-mentioned driving device includes two second driving circuits, and the driving voltage of each electromagnetic drive coil is controlled by a second driving circuit.

[0100] It should be noted that the aforementioned swingable device may also include a voltage conversion circuit. This circuit converts the input voltage into voltages of different magnitudes to provide matching voltages to the first and / or second drive circuits. For example, in the case where the first drive circuit includes an STC8A8K64D chip and the second drive circuit includes an L6205 chip, the STC8A8K64D chip operates at 5V, and the L6205 chip operates at 24V. The swingable device is connected to 220V AC power via a 24V adapter. After passing through a low-voltage fuse, the 24V voltage can be supplied to the L6205 chip and the voltage conversion circuit.

When a DC power supply below 36V is input, it is converted by the power conversion module and then supplied to the MCU. Under the combined action of the MCU, Hall sensor array, drive circuit and electromagnetic drive coil, the motion of the object is achieved.

[0107] The arrangement of multiple Hall sensors is not limited; for example, they can be arranged in a line. Hall sensors can detect the amplitude and frequency of the swinging component by monitoring changes in magnetic field lines and transmit the detection results to the drive device.

[0109] By incorporating Hall effect sensors, the swing position signal of the swingable component can be quickly and accurately provided to the drive device, thereby improving the overall response speed and accuracy of the device.

[0110] The following provides information such as Figure 3a The diagram shows the specific circuit structure of each part.

[0111] The Hall effect circuit is as follows: It uses 16 Hall sensors, and the circuit design of each Hall sensor is as follows. Figure 3c As shown, Figure 3c Figures a1-a16 illustrate the circuit design structures of 16 Hall sensors, with each Hall sensor having the same circuit design structure. Figures a19 and a20 show the design structure diagrams of two 74HC165 chipsets, with the 16 Hall sensors working in conjunction with the 74HC165 to process and output data signals.

Figure 3a The MCU shown uses, for example Figure 3fThe circuit design shown uses the STC8A8K64D4 main control chip to process data from the remote control, Hall sensor, driver chip, serial port, and backup interface. After reading the Hall sensor data via the CN7 interface, the MCU outputs a variable PWM control signal from the I / O port to two L6205 chips based on the Hall sensor value. The two L6205 chips output varying voltage values, which are transmitted through CN4 and CN12 to the drive coil. The drive coil generates a changing magnetic field that attracts or repels the magnets on the device, thus producing mechanical motion.

[0117] The following provides the specific structure of a rocking device. This rocking device is a rocking chair, for reference. Figure 4 As shown, the swingable assembly includes a bracket 121, a support member 122, and connecting rods 123. The bracket 121 supports the user's body, and the support member 122 is fixedly connected to the bottom of the bracket 121. The support member 122 has a horizontal bar and two vertical bars, with the horizontal bar connecting between the vertical bars. The horizontal bar and vertical bars form an n-shaped structure to improve the structural strength of the support frame. The horizontal bar is connected to the bottom of the bracket 121. There are multiple connecting rods 123, each corresponding to one of the vertical bars. Figure 2 In the bracket 121, there are two support members 122, which are spaced apart at the bottom of the bracket 121. The electromagnetic drive coil 114 is located between the two support members 122 to protect the electromagnetic drive coil 114.

[0118] The support assembly includes a support leg 111 and a mounting base 112. The support leg 111 is fixedly connected to the mounting base 112 to support the mounting base 112. The support leg 111 can be a frame structure bent from stainless steel tubing. The mounting base 112 can be a groove-shaped structure with a base plate and side plates, the opening of the groove-shaped structure facing the swing frame 120. The support leg 111 is welded to the bottom or side plate of the mounting base 112. One end of the connecting rod 123 is rotatably connected to a vertical rod, and the other end of the connecting rod 123 is rotatably connected to the mounting base 112. The connection points between the connecting rod 123 and the support member 122 can all be connected by ball bearings to reduce friction at the connection points.

[0119] The second magnetic unit includes two electromagnetic drive coils 114. The drive device includes a circuit board 115 and a power supply device 130. The circuit board 115 is mounted on the base plate of the mounting base 112, and the two electromagnetic drive coils 114 are mounted on the circuit board 115. The circuit board 115 and the power supply device 130 are electrically connected.

[0120] The first magnetic unit includes two permanent magnets 125; the support assembly also includes a protective shell 116, which is connected to the mounting base 112 and covers the permanent magnets 125 to protect them.

[0121] The following explains the swinging principle of the rocking chair. For ease of description, the magnetic fields generated by the two electromagnetic drive coils are referred to as the first magnetic field and the second magnetic field, respectively. The polarities of the first magnetic field and the second magnetic field are opposite.

[0122] During the startup phase, the drive device outputs a drive voltage to the second magnetic unit, which generates a magnetic field. Because the second and first magnetic units are relatively eccentrically positioned, the first magnetic unit, under the combined action of the repulsive force of the first magnetic field (equivalent to a pushing effect) and the magnetic attraction force of the second magnetic field (equivalent to a pulling effect), moves towards the reference... Figure 5 As shown, the swingable component is driven to swing from the initial position a0 to the preset position a1. When it reaches the preset position a1, the driving device changes the polarity of the driving voltage, and the polarities of the first magnetic field and the second magnetic field change. Under the combined action of the magnetic attraction force of the first magnetic field (equivalent to pulling) and the repulsive force of the second magnetic field (equivalent to pushing), the first magnetic unit drives the swingable component to swing from the preset position a1 to the preset position b1. When it reaches the preset position b1, the driving device changes the polarity of the driving voltage, and the polarities of the first magnetic field and the second magnetic field change again. Under the combined action of the repulsive force of the first magnetic field (equivalent to pushing) and the magnetic attraction force of the second magnetic field (equivalent to pulling), the first magnetic unit drives the swingable component to swing from the preset position b1 to the preset position a2. This process is repeated until the swing amplitude of the swingable component reaches the preset amplitude. It should be noted that the swing amplitude corresponding to the preset position a1 is smaller than the swing amplitude corresponding to the preset position a2, and the swing amplitude corresponding to the preset position b1 is smaller than the swing amplitude corresponding to the preset position b2.

[0123] Throughout the startup phase, the drive unit continuously outputs drive voltage to the two electromagnetic drive coils, with the polarities of the drive voltages being opposite. During startup, the swingable component can swing without the need for additional thrust, reducing user operation, simplifying product use, and further enhancing product performance.

[0124] During the operational phase, refer to Figure 6As shown, at the first position A1 and the second position A2, the absolute value of the driving voltage of the two electromagnetic drive coils is the minimum, which can be zero; at the middle position A, the absolute value of the driving voltage is the maximum. When swinging from the first position A1 to the middle position A, the absolute value of the driving voltage of the two electromagnetic drive coils gradually increases; when swinging from the middle position A to the second position A2, the absolute value of the driving voltage of the two electromagnetic drive coils gradually decreases; when reaching the second position A2, the polarity of the driving voltage of the two electromagnetic drive coils reverses simultaneously; when swinging from the second position A2 to the middle position A, the absolute value of the driving voltage of the two electromagnetic drive coils gradually increases; when swinging from the middle position A to the second position A2, the absolute value of the driving voltage of the two electromagnetic drive coils gradually decreases; this process repeats, realizing the back-and-forth swinging of the swingable component between the first position A1 and the second position A2.

[0125] This invention also provides a driving method based on the above-described swingable device, with reference to... Figure 7 As shown, it includes:

[0126] S01, The control switch outputs a control signal to the drive unit.

[0127] S02, The sensor detects the position of the swingable component to obtain the swing position signal; the swing position signal is transmitted to the drive device.

[0128] S03. During the startup phase, the drive device outputs a drive voltage to the second magnetic unit according to the control signal, so that the swing amplitude of the swingable component reaches the target swing amplitude from the initial swing amplitude; according to the swing position signal, when the swing amplitude of the swingable component reaches the preset swing amplitude, the polarity of the drive voltage is adjusted so that the swingable component swings back and forth; during the operation phase, the swing direction and swing amplitude of the swingable component are determined according to the swing position signal; according to the swing direction of the swingable component, the absolute value of the drive voltage is adjusted so that the absolute value of the drive voltage is the largest when the swingable component swings to the middle position, and the absolute value of the drive voltage is the smallest when the swingable component swings to the first position or the second position, wherein the middle position corresponds to the swingable component swinging to the minimum swing amplitude, and the first position and the second position respectively correspond to the swingable component swinging to the target swing amplitude in different swing directions; according to the swing amplitude of the swingable component, when the swing amplitude of the swingable component reaches the target swing amplitude, the polarity of the drive voltage is adjusted so that the swingable component swings back and forth between the first position and the second position.

[0129] The description of the swingable device in the above driving method can be found in the foregoing embodiments, and will not be repeated here.

[0130] The driving method of this swingable device is simple and easy to implement. By controlling the swingable device through this driving method, vibration and noise can be significantly reduced, thereby greatly improving product performance. At the same time, during the operation phase, the acceleration and deceleration processes can be slowed down to avoid large shaking during the swinging process, making the swinging component swing more smoothly, thereby further improving product performance. During the start-up phase, the swinging component can be started to swing solely by the magnetic attraction and / or repulsion force of the magnetic field generated by the second magnetic unit, without the need to apply additional thrust, reducing user operation, lowering the difficulty of product use, and further improving product performance.
