[0063] Embodiment 1:

[0064] like Figure 1-Figure 4 As shown, the rhythmic furniture provided in the first embodiment of the present invention includes a fixed frame 20, a movable frame 10, a connecting mechanism 40 and an electromagnetic driving mechanism 30. The movable frame 10 is used to install furniture cushions. Furniture cushions refer to intermediaries used to bear the weight of the human body, and can be selected according to the type of rhythmic furniture. For example, if the rhythmic furniture is a rhythmic chair, the furniture cushions are chair cushions. If the rhythmic furniture is a rhythmic bed, the furniture cushions are mattresses. There is no specific limitation. The shape of the movable frame 10 can be selected according to the type of rhythmic furniture. If the rhythmic furniture is a rhythmic chair, the movable frame 10 is L-shaped. If the rhythmic furniture is a rhythmic chair, the movable frame 10 is flat. For reference, Figure 1The shape of the moving frame in the figure. The fixed frame 20 is used to support the moving frame 10. The fixed frame 20 is a base and is generally installed on the ground during use. The connecting mechanism 40 is respectively connected to the moving frame 10 and the fixed frame 20 so that the fixed frame 20 can support the starting frame 10. As an embodiment, the connection method of the connecting mechanism 40 with the moving frame 10 and the fixed frame 20 determines that the fixed frame 20 supports the moving frame 10 in the form of a support or a hang. For example, in the form of a support, the connecting mechanism 40 includes an upper and lower end portion in the vertical direction, the upper end portion 411 is connected to the moving frame 10, and the lower end portion 412 is connected to the fixed frame 20. For example, in the form of a hang, please refer to Figure 1 and Figure 2 ,in Figure 2 In order to clearly observe the structure of the connecting member, one side of the frame body 12 of the movable frame 10 is not Figure 2 As shown in the figure, the connecting mechanism 40 includes four connecting members 41, and the connecting member 41 includes upper and lower ends in the vertical direction. The upper end 411 is connected to the fixed frame 20 through the connecting portion 21 of the fixed frame, and the lower end 412 is connected to the movable frame 10 through the connecting portion 11 of the movable frame. In the vertical direction, the connecting portion 21 of the fixed frame is higher than the connecting portion 11 of the movable frame.

[0065] As an embodiment, the rhythmic furniture further includes an electromagnetic drive mechanism 30, such as Figure 3 , Figure 4 As shown, the electromagnetic driving mechanism 30 is used to generate a driving force, and the driving force acts on the movable frame 10 or the fixed frame 20, so that the movable frame 10 generates a back-and-forth reciprocating motion relative to the fixed frame 20, that is, a rhythmic motion. As an embodiment, the electromagnetic drive mechanism 30 includes a first magnetic member 31, a second magnetic member 32, a controller 33 and a temperature sensor 34. The first magnetic member 31 includes a coil 311, a mounting bracket 312 and a power supply device. The coil 311 is connected to the power supply device. The coil 311 is installed on the mounting bracket 312. The mounting bracket 312 is connected to the fixed frame 20. The power supply device is used to provide an alternating current of a first frequency to the coil 311 to generate a magnetic field with a changed magnetic pole. The magnetic pole of the second magnetic member 32 remains unchanged. The first magnetic member 31 and the second magnetic member 32 are respectively located within the magnetic field range of each other so that the change of the magnetic pole of the first magnetic member 31 causes a relative reciprocating displacement between the first magnetic member 31 and the second magnetic member 32 in the horizontal direction. The first magnetic member 31 is connected to one of the moving frame 10 and the fixed frame 20 and the relative position remains unchanged. The second magnetic member 32 is connected to the other of the moving frame 10 and the fixed frame 20 and the relative position remains unchanged. The temperature sensor 34 is used to detect the temperature of the coil 311.

[0066] As an implementation mode, the controller 33 is configured to: obtain the first temperature of the coil 311 of the first magnetic member 31, and if the first temperature is greater than or equal to the first preset temperature, adjust the AC power provided by the power supply device from the first frequency to the second frequency, and the second frequency is less than the first frequency. In the related art, there are two driving modes of rhythmic furniture: motor drive and electromagnetic drive mechanism 30 drive. In the rhythmic furniture driven by the motor, the principle of the motor drive mode is that the output shaft of the motor outputs rotational motion. In order to achieve the rhythmic effect of the forward and backward movement of the rhythmic furniture, the motor-driven rhythmic furniture needs to be equipped with a transmission structure to convert the rotational motion into the forward and backward motion. In the related art, a cam transmission mode is adopted. This driving scheme includes a transmission cam, which converts the rotational motion output by the motor into a linear motion to achieve the forward and backward movement of the rhythmic furniture. Since the initial output of the motor drive is rotational motion, it has the advantage of being able to set a reduction mechanism, that is, to achieve a larger torque through a reduction wheel, and the motor can meet the power requirements of the rhythmic furniture with a smaller power. At the same time, due to the small power, the heat generated by the motor drive mode is also relatively small, and there is no need to do too much technical design on the heat dissipation of the motor, and a traditional heat dissipation fan can be used. However, the rhythmic furniture driven by a motor needs to go through a deceleration structure, a cam structure, etc., which makes the motor-driven rhythmic furniture generate a lot of noise during operation, which greatly affects the experience of the users of the rhythmic furniture. Therefore, the rhythmic furniture of this embodiment uses an electromagnetic drive mechanism 30 as a driving force. The rhythmic furniture using the electromagnetic drive mechanism 30 as a driving force has the advantage of low noise, which is very consistent with the low-noise environmental use requirements of rhythmic furniture. In some embodiments, the first magnetic member 31 is connected to the fixed frame 20, and the second magnetic member 32 is connected to the moving frame 10. The following description takes this connection method as an example. It can be understood that the first magnetic member 31 is also connected to the moving frame 10, and the second magnetic member 32 is connected to the fixed frame 20.

[0067] When powered on, the first magnetic member 31 and the second magnetic member 32 produce relative reciprocating displacement in the horizontal direction. This is the difference between the electromagnetic drive mechanism 30 and the motor drive. The electromagnetic drive mechanism 30 directly outputs the movement in the horizontal direction. The movable frame 10 is connected to the second magnetic member 32. The movable frame 10 moves with the movement of the second magnetic member 32, and the movement speed of the second magnetic member 32 is consistent with the movement speed of the movable frame 10, that is, there is no speed change device connected between the second magnetic member 32 and the movable frame 10. Due to the supporting or hanging effect of the connecting mechanism 40, the movable frame 10 is kept above the fixed frame 20, that is, the second magnetic member 32 can also be kept at a specific height and does not contact the first magnetic member 31, so that the noise is small during operation. The movement speed of the second magnetic member 32 in the electromagnetic drive mechanism 30 is consistent with the movement speed of the movable frame 10, and since there is no speed change mechanism between the electromagnetic drive mechanism 30 and the movable frame 10, it can be understood that the electromagnetic drive mechanism 30 requires a larger input power for the same torque, that is, more heat is generated during operation using the electromagnetic drive mechanism 30. Since the traditional motor drive outputs rotary motion, a reduction device can be used to achieve lower power to meet the motion requirements of the moving frame 10. Since the electromagnetic drive mechanism 30 outputs horizontal motion, it is not suitable to use a reduction device based on noise reduction and structural design. At this time, compared with the motor drive, the electromagnetic drive mechanism 30 requires a larger input power, which will generate more heat. In the traditional drive method of heat dissipation, fans or water cooling are often used to dissipate heat. However, due to the long-term operation of the rhythmic furniture, the traditional heat dissipation method cannot effectively dissipate heat, resulting in the technical problem of low life of the electromagnetic drive mechanism 30. The controller 33 used in this embodiment obtains the temperature of the coil 311 in the first magnetic part 31 of the input alternating current. If the temperature is greater than or equal to the preset temperature, the power supply device is controlled to adjust the provided alternating current from the first frequency to the second frequency, and the second frequency is less than the first frequency. By reducing the frequency of the first magnetic part 31 after reaching the preset temperature, the power of the first magnetic part 31 is reduced, thereby reducing the heat generated by the first magnetic part 31, so as to extend the service life of the electromagnetic drive mechanism 30. In general drive scheme design, it is not inclined to reduce the temperature by reducing heat generation by frequency reduction, because the user sets the operating parameters of the drive mechanism, and the drive scheme design will try to meet the needs of the user as much as possible, and frequency reduction will not meet the needs of the user. In this embodiment, since it involves rhythmic furniture, the rhythmic furniture achieves the rhythmic effect by moving back and forth, and the user may feel uncomfortable if it takes too long, it is necessary to reduce the frequency of the electromagnetic drive mechanism 30 to reduce the operating frequency of the moving frame 10, so as to avoid user discomfort. Therefore, based on the user comfort of the rhythmic furniture, the internal electromagnetic drive mechanism 30 frequency reduction to reduce heat generation and the external moving frame 10 frequency reduction to avoid user discomfort are combined, so that the service life of the electromagnetic drive mechanism 30 is extended and coordinated with the user's comfort.

[0068] In some embodiments, the second magnetic member 32 includes an annular magnet 321 and a connecting rod 322, the connecting rod 322 is inserted into the annular magnet 321, the relative position between the annular magnet 321 and the connecting rod 322 remains unchanged, the end of the connecting rod 322 is connected to the movable frame 10, and the relative position between the two remains unchanged. When the annular magnet 321 moves, it can drive the connecting rod 322 to move, thereby driving the movable frame 10 to move. In some embodiments, the annular magnet 321 is an annular permanent magnet with a simple structure and low operating cost of the electromagnetic drive mechanism. In some embodiments, the annular magnet 321 is an energized coil, and the second magnetic member also includes a power supply device, which is connected to the energized coil to supply power to the energized coil so that the energized coil generates a magnetic field. In some embodiments, the power supply device provides direct current to the energized coil so that the magnetic pole of the energized coil of the second magnetic member remains unchanged. In some embodiments, the power supply device provides alternating current to the energized coil of the second magnetic component, and the time when the current direction of the provided alternating current changes is different from the time when the current direction of the alternating current provided by the power supply device of the first magnetic component changes, so that the time when the magnetic pole of the first magnetic component changes is different from the time when the magnetic pole of the second magnetic component changes, thereby causing a reciprocating relative displacement between the first magnetic component and the second magnetic component.

[0069] In some embodiments, both ends of the connecting rod 322 are fixedly connected to the movable frame 10, and the annular permanent magnet 321 is located between the two ends of the connecting rod 322. The connection method between the two ends of the connecting rod 322 and the movable frame 10 can be bolt connection, rivet connection, etc., without specific limitation.

[0070] In some embodiments, the connection method of the movable frame 10 being suspended and connected to the fixed frame 20 is taken as an example. Figure 2 As shown, the connection mechanism 40 includes four connecting members 41, and the connecting member 41 includes upper and lower ends in the vertical direction, and the upper end 411 is higher than the lower end 412. The upper end 411 of the connecting member 41 is connected to the fixed frame 20 through the connecting portion 21 of the fixed frame, and the lower end 412 of the connecting member 41 is connected to the movable frame 10 through the connecting portion 11 of the movable frame. The movable frame 10 includes a frame body 12 and a protrusion 13 extending vertically downward along the edge of the frame body 12. The frame body 12 of the movable frame 10 is located above the fixed frame 20, and the protrusion 13 is provided with the connecting portion 11 of the movable frame. The connecting portion 11 of the movable frame is lower than the connecting portion 21 of the fixed frame, so that the movable frame 10 is suspended on the fixed frame 20 as a whole. The upper and lower ends of the connecting member 41 are connected to the connecting portion 11 of the movable frame and the connecting portion 21 of the fixed frame by rotational connection, for example, it can be a rotating shaft connection or a bearing connection. In some embodiments, the connecting member 41 may be a rigid member or an elastic structure, such as a spring structure or a spring sheet structure, without any specific limitation.

[0071] In some embodiments, the temperature sensor 34 is a thermal resistance sensor, which is used to measure the temperature of the coil 311 of the first magnetic member.

[0072] In some embodiments, the controller 33 is further configured to adjust the first frequency to the second frequency as a linear adjustment. Through the linear adjustment, the frequency reduction process is gradual, so that the frequency reduction process of the reciprocating motion of the movable frame 10 is also gradual, so that the user can slowly adapt to the process of reducing the reciprocating frequency of the movable frame 10, avoiding discomfort to the user due to the sudden reduction of the motion frequency of the movable frame 10. Linear adjustment means that the change value of the frequency in a unit time remains unchanged.

[0073] In some embodiments, the controller 33 is also configured to, when the first temperature is greater than or equal to the first preset temperature, control the power supply device of the first magnetic component 31 to switch the first frequency to the second frequency. Different from linear adjustment, the controller 33 switches the first frequency to the second frequency by directly setting the output voltage of the power supply device of the first magnetic component 31 to the second frequency, thereby achieving rapid frequency reduction, reducing the output power of the electromagnetic drive mechanism 30, and reducing heat dissipation. This solution helps to quickly reduce heat generation, better protect the electromagnetic drive mechanism 30, and avoid overheating that causes failure of the electromagnetic drive mechanism 30 or reduces the service life of the electromagnetic drive mechanism 30.

[0074] In some embodiments, the controller 33 is also configured to adjust the first frequency to the second frequency in a sinusoidal manner, that is, the frequency reduction process is also gradual, but not linear, but sinusoidal, that is, the time and frequency change curve is a sinusoidal curve. This solution can also avoid sudden frequency reduction causing discomfort to the user.

[0075] In some embodiments, the controller 33 is further configured to obtain the second temperature of the coil 311 of the first magnetic part 31 after adjusting the alternating current provided by the power supply device of the first magnetic part 31 to the second frequency, and if the second temperature is less than or equal to the second preset temperature, control the power supply device of the first magnetic part 31 to adjust to the first frequency. By setting the second preset temperature, the rhythmic furniture will not be in a frequency reduction state for a long time after the frequency reduction, and the rhythmic furniture will return to a high-frequency operation state after the second preset temperature is met, thereby improving the user experience. The second preset temperature is generally a safe temperature for the electromagnetic drive mechanism 30 to operate for a long time, and can be adjusted according to the characteristics of the electromagnetic drive mechanism 30, for example, it can be 80°C.

[0076] In some embodiments, the second frequency range is 2 Hz-5 Hz, and the electromagnetic drive mechanism 30 operating in this frequency range can well balance the cooling demand and the user comfort.

[0077] In some embodiments, the controller 33 is further configured to include a first operating mode and a second operating mode. When the electromagnetic drive mechanism 30 is in the first operating mode, the power supply device of the first magnetic member 31 provides an alternating current of a first frequency. When the electromagnetic drive mechanism 30 is in the second operating mode, the power supply device of the first magnetic member 31 provides an alternating current of a third frequency. The third frequency is less than the first frequency, and the second frequency is different from the third frequency. This embodiment provides a plurality of operating modes of rhythmic furniture. The rhythmic furniture of different operating modes corresponds to input alternating currents of different frequencies. Since the frequency corresponds to the switching speed of the alternating current, if the frequency is higher, for example, the moving frame 10 of the rhythmic furniture at the first frequency moves back and forth more quickly, on the contrary, the moving frame 10 of the rhythmic furniture at the third frequency moves back and forth more slowly. This can meet the user's use needs in different scenarios. For example, the first frequency is a high frequency, and the moving frame 10 moves back and forth quickly, which can enable the user to obtain a better exercise effect on the whole body, which is beneficial to fat loss; the third frequency is a low frequency, and the moving frame 10 moves back and forth slowly, which can enable the user to relax the whole body, which is beneficial to promoting intestinal digestion. In different operating modes, the mode with the highest frequency generates higher heat. In order to make the electromagnetic drive mechanism 30 meet the requirements of different operating modes, it is necessary to control the heat generation of the high-frequency mode. This embodiment is conducive to meeting the operating requirements of multiple operating modes for the electromagnetic drive mechanism 30.

[0078] In some embodiments, the controller 33 is further configured to control the power supply device of the first magnetic member 31 to adjust to the first frequency after the AC power provided by the power supply device of the first magnetic member 31 is adjusted to the second frequency after a first preset time. As mentioned above, after the frequency is reduced, if the temperature is reduced to a certain temperature and then the frequency is increased, this temperature is generally a safe operating temperature. However, in practice, sometimes the temperature of the electromagnetic drive motor cannot be reduced to a specific safe operating temperature for a long time due to the influence of the external environment. However, because the electromagnetic drive motor has been running at a low frequency for a certain period of time, it has been cooling down during the operation process, but has not reached the safe operating temperature. However, the electromagnetic drive mechanism 30 after cooling can already meet the high-frequency operation requirements, so the frequency can be increased to avoid being in a low-frequency state for a long time and affecting the user experience. The first preset time is the result obtained by the applicant through practical tests. Generally, running at a low frequency for 30 minutes can meet the operating requirements of the electromagnetic drive mechanism 30 at a high frequency.

[0079] In some embodiments, the controller 33 is further configured to, after adjusting the AC power provided by the power supply device of the first magnetic part 31 to the second frequency, control the power supply device of the first magnetic part 31 to adjust to the first frequency based on the received instruction to adjust the AC power provided by the power supply device of the first magnetic part 31 to the first frequency. The received instruction is not generated by the controller 33, but comes from outside the controller 33, for example, it can be user input, the user can input the instruction through remote control, network or control panel based on rhythmic furniture; it can also be input from an external linkage device, such as through an external computer device. Through the convenient instruction input system, the user can complete the frequency adjustment operation, which is conducive to realizing diversified user adjustments and increasing the convenience and experience of user operation.

[0080] In some embodiments, the controller 33 is further configured to adjust the AC power provided by the power supply device of the first magnetic member 31 from the first frequency to the second frequency after the power supply device of the first magnetic member 31 provides the AC power of the first frequency for a second preset time. The first frequency is a high frequency, and the second frequency is a low frequency. The adjustment to the low frequency is to reduce heat generation. The present application relates to rhythmic furniture, and the user needs to lie or sit on the furniture cushion. The user moves back and forth based on the back and forth movement of the moving frame 10 to achieve the effect of exercise or digestion. When a high frequency is used, the moving frame 10 moves back and forth faster. If the time is too long, it may cause discomfort to the user; in addition, if the frequency reduction condition is not triggered for a long time, the electromagnetic drive mechanism 30 is in a high-frequency operation state for a long time, which is not conducive to the service life of the electromagnetic drive mechanism 30. Therefore, by setting the second preset time as the frequency reduction condition of the electromagnetic drive mechanism 30, it is conducive to extending the service life of the electromagnetic drive mechanism 30 while satisfying the user's comfort.

[0081] Embodiment 2:

[0082] The main difference between this embodiment and the first embodiment is that the application subject of the controller 33 is different, which is specifically reflected in that: the first embodiment is used in the rhythmic furniture including the electromagnetic drive mechanism 30, and this embodiment is used for the electromagnetic drive mechanism 30.

[0083] Specifically, the electromagnetic drive mechanism 30 provided in the second embodiment includes a first magnetic member 31, a second magnetic member 32, a controller 33 and a temperature sensor 34. The first magnetic member 31 includes a coil 311 and a power supply device. The coil 311 is connected to the power supply device. The power supply device is used to provide an alternating current of a first frequency to the coil 311 to generate a magnetic field with a changed magnetic pole. The magnetic pole of the second magnetic member 32 remains unchanged. The first magnetic member 31 and the second magnetic member 32 are respectively located within the magnetic field range of each other so that the change of the magnetic pole of the first magnetic member 31 causes a relative reciprocating displacement between the first magnetic member 31 and the second magnetic member 32 in the horizontal direction. The first magnetic member 31 is connected to one of the movable frame 10 and the fixed frame 20 and the relative position remains unchanged. The second magnetic member 32 is connected to the other of the movable frame 10 and the fixed frame 20 and the relative position remains unchanged. The temperature sensor 34 is used to detect the temperature of the coil 311. The controller 33 is configured to: obtain a first temperature of the coil 311, and if the first temperature is greater than or equal to the first preset temperature, adjust the alternating current provided by the power supply device from the first frequency to the second frequency, and the second frequency is less than the first frequency. The controller 33 used in this embodiment obtains the temperature of the first magnetic member 31 through which the alternating current is supplied, and if the temperature is greater than or equal to a preset temperature, controls the power supply device to adjust the provided alternating current from the first frequency to the second frequency, where the second frequency is less than the first frequency. By reducing the frequency after the first magnetic member 31 reaches the preset temperature, the power of the first magnetic member 31 is reduced, thereby reducing the heat generated by the first magnetic member 31, so as to extend the service life of the electromagnetic drive mechanism 30.

[0084] In some embodiments, the first magnetic member 31 includes a coil 311 and a power supply device, the coil 311 is connected to the power supply device, the second magnetic member 32 includes an annular magnet 321 and a connecting rod 322, the connecting rod 322 is inserted into the annular magnet 321, the relative position between the annular magnet 321 and the connecting rod 322 remains unchanged, the end of the connecting rod 322 is connected to the movable frame 10, and the relative position between the two remains unchanged. When the annular magnet 321 moves, it can drive the connecting rod 322 to move. In some embodiments, the annular magnet 321 is an annular permanent magnet with a simple structure and low operating cost of the electromagnetic drive mechanism. In some embodiments, the annular magnet 321 is an energized coil, and the second magnetic member also includes a power supply device, which is connected to the energized coil to supply power to the energized coil so that the energized coil generates a magnetic field. In some embodiments, the power supply device provides direct current to the energized coil so that the magnetic pole of the energized coil of the second magnetic member remains unchanged. In some embodiments, the power supply device provides alternating current to the energized coil of the second magnetic component, and the time when the current direction of the provided alternating current changes is different from the time when the current direction of the alternating current provided by the power supply device of the first magnetic component changes, so that the time when the magnetic pole of the first magnetic component changes is different from the time when the magnetic pole of the second magnetic component changes, thereby causing a reciprocating relative displacement between the first magnetic component and the second magnetic component.

[0085] In some embodiments, the temperature sensor 34 is a thermal resistance sensor, which is used to measure the temperature of the coil 311 of the first magnetic member.

[0086] In some embodiments, the controller 33 is further configured to adjust the first frequency to the second frequency as a linear adjustment, and the frequency reduction process is gradual through the linear adjustment, so that the frequency reduction process of the reciprocating motion of the second magnetic member 32 is also gradual, and after the electromagnetic drive mechanism 30 is assembled, the second magnetic member 32 is used as the output end, so that the mechanism connected to the output end also moves gradually. Linear adjustment means that the change value of the frequency per unit time remains unchanged.

[0087] In some embodiments, the controller 33 is further configured to obtain the second temperature of the coil 311 of the first magnetic member 31 after adjusting the alternating current provided by the power supply device of the first magnetic member 31 to the second frequency, and if the second temperature is less than or equal to the second preset temperature, control the power supply device to adjust to the first frequency. By setting the second preset temperature, the electromagnetic drive mechanism 30 will not be in a frequency reduction state for a long time after the frequency reduction, and the electromagnetic drive mechanism 30 will return to the high-frequency operation state after the second preset temperature is met. The second preset temperature is generally a safe temperature for the electromagnetic drive mechanism 30 to run for a long time, which can be adjusted according to the characteristics of the electromagnetic drive mechanism 30, for example, it can be 80°C.

[0088] In some embodiments, the controller 33 is further configured to include a first operating mode and a second operating mode. When the electromagnetic drive mechanism 30 is in the first operating mode, the power supply device of the first magnetic member 31 provides an alternating current of a first frequency. When the electromagnetic drive mechanism 30 is in the second operating mode, the power supply device of the first magnetic member 31 provides an alternating current of a third frequency. The third frequency is less than the first frequency, and the second frequency is different from the third frequency. This embodiment provides an electromagnetic drive mechanism 30 with multiple operating modes. The electromagnetic drive mechanisms 30 with different operating modes correspond to input alternating currents of different frequencies. Since the frequency corresponds to the switching speed of the alternating current, if the frequency is higher, for example, the second magnetic member 32 of the electromagnetic drive mechanism 30 at the first frequency moves back and forth more quickly, and vice versa, the second magnetic member 32 of the electromagnetic drive mechanism 30 at the third frequency moves back and forth more slowly. This can meet the use requirements of the electromagnetic drive mechanism 30 in different scenarios. For example, if the first frequency is high frequency, the second magnetic member 32 moves back and forth quickly; if the third frequency is low frequency, the second magnetic member 32 moves back and forth slowly. In different operating modes, the mode with the highest frequency generates higher heat. In order to make the electromagnetic drive mechanism 30 meet the requirements of different operating modes, it is necessary to control the heat generation of the high-frequency mode. This embodiment is conducive to meeting the operating requirements of multiple operating modes for the electromagnetic drive mechanism 30.

[0089] Embodiment three:

[0090] like Figure 5 As shown, the difference between this embodiment and the first embodiment mainly lies in the different subjects of protection, which are specifically reflected in: the first embodiment protects rhythmic furniture, which includes an electromagnetic drive mechanism 30 with a controller 33, and the third embodiment protects a control method, which is a method for controlling the operation of the electromagnetic drive mechanism 30 of the rhythmic furniture.

[0091] Specifically, the control method of the rhythmic furniture of the present embodiment is applied to the rhythmic furniture, which includes a moving frame 10 for installing furniture cushions, a fixed frame 20 for supporting the moving frame 10, an electromagnetic drive mechanism 30 and a connecting mechanism 40, wherein the electromagnetic drive mechanism 30 includes a first magnetic member 31, a second magnetic member 32, a controller 33 and a temperature sensor 34, the first magnetic member 31 includes a coil 311 and a power supply device, the coil 311 is connected to the power supply device, and the power supply device is used to provide alternating current of a first frequency to the coil 311 to generate a magnetic field with a changing magnetic pole, the magnetic pole of the second magnetic member 32 remains unchanged, and the first magnetic member 31 and the second magnetic member 32 are respectively located at magnetic poles of each other. The invention relates to a method for controlling the movement of the movable frame 10 and the fixed frame 20 so that the magnetic pole of the first magnetic member 31 changes, causing the first magnetic member 31 and the second magnetic member 32 to generate a relative reciprocating displacement in the horizontal direction. The first magnetic member 31 is connected to one of the movable frame 10 and the fixed frame 20 and the relative position remains unchanged. The second magnetic member 32 is connected to the other of the movable frame 10 and the fixed frame 20 and the relative position remains unchanged. The temperature sensor 34 is used to detect the temperature of the coil 311. The connecting mechanism 40 is used to connect the movable frame 10 and the fixed frame 20, so that the relative movement between the second magnetic member 32 and the first magnetic member 31 generates a movement of the movable frame 10 relative to the fixed frame 20 at the same speed as the relative movement, including the following steps:

[0092] Step S101 : the controller 33 obtains a first temperature of the coil 311 .

[0093] Step S102: If the first temperature is greater than or equal to the first preset temperature, the controller 33 adjusts the AC power provided by the power supply device from the first frequency to the second frequency, where the second frequency is lower than the first frequency.

[0094] Specifically, after obtaining the first temperature of the coil 311 of the first magnetic part 31, the controller 33 determines whether the first temperature is greater than or equal to the first preset temperature. If so, the controller 33 adjusts the AC power provided by the power supply device from the first frequency to the second frequency, and the second frequency is less than the first frequency. By obtaining the temperature of the coil 311 in the first magnetic part 31, if the temperature is greater than or equal to the preset temperature, the power supply device is controlled to adjust the AC power provided from the first frequency to the second frequency, and the second frequency is less than the first frequency. By reducing the frequency after the first magnetic part 31 reaches the preset temperature, the power of the first magnetic part 31 is reduced, thereby reducing the heat generated by the first magnetic part 31, so as to extend the service life of the electromagnetic drive mechanism 30.

[0095] In some embodiments, step S103 is also included: after the controller 33 adjusts the AC power provided by the power supply device to the second frequency, the controller 33 obtains the second temperature of the coil 311. If the second temperature is less than or equal to the second preset temperature, the controller 33 controls the power supply device to adjust to the first frequency.

[0096] Specifically, after the controller 33 adjusts the AC power provided by the power supply device to the second frequency, the controller 33 obtains the second temperature of the coil 311 and determines whether the second temperature is less than or equal to the second preset temperature. If so, the controller 33 controls the power supply device to adjust to the first frequency. By setting the second preset temperature, the rhythmic furniture will not be in a reduced frequency state for a long time after the frequency is reduced, and the rhythmic furniture will return to a high-frequency operation state after the second preset temperature is met. The second preset temperature is generally a safe temperature for the electromagnetic drive mechanism 30 to operate for a long time, and can be adjusted according to the characteristics of the electromagnetic drive mechanism 30, for example, it can be 80°C.

[0097] In some embodiments, in step S102, the controller 33 adjusts the AC power provided by the power supply device from the first frequency to the second frequency in a linear adjustment process. Through the linear adjustment, the frequency reduction process is gradual, so that the frequency reduction process of the reciprocating motion of the movable frame 10 is also gradual, so that the user can slowly adapt to the process of reducing the reciprocating frequency of the movable frame 10, avoiding discomfort to the user due to the sudden reduction of the motion frequency of the movable frame 10. Linear adjustment means that the change value of the frequency in a unit time remains unchanged.

[0098] Embodiment 4:

[0099] The difference between this embodiment and the second embodiment mainly lies in the different subjects of protection, which is specifically reflected in that: the second embodiment protects the electromagnetic drive mechanism 30 with a controller 33, and the fourth embodiment protects the control method, which is a method for controlling the operation of the electromagnetic drive mechanism 30.

[0100] Based on the electromagnetic drive mechanism 30 of the second embodiment, the present application provides a control method of the electromagnetic drive mechanism 30, which can be executed by the electromagnetic drive mechanism 30 of the second embodiment. Figure 6 , which may include the following steps:

[0101] S201 : the controller 33 obtains a first temperature of the coil 311 .

[0102] S202: If the first temperature is greater than or equal to the first preset temperature, the controller 33 adjusts the AC power provided by the power supply device from the first frequency to a second frequency, where the second frequency is lower than the first frequency.

[0103] Specifically, after obtaining the first temperature of the coil 311 of the first magnetic part 31, the controller 33 determines whether the first temperature is greater than or equal to the first preset temperature. If so, the controller 33 adjusts the AC power provided by the power supply device from the first frequency to the second frequency, and the second frequency is less than the first frequency. By obtaining the temperature of the coil 311 in the first magnetic part 31, if the temperature is greater than or equal to the preset temperature, the power supply device is controlled to adjust the AC power provided from the first frequency to the second frequency, and the second frequency is less than the first frequency. By reducing the frequency after the first magnetic part 31 reaches the preset temperature, the power of the first magnetic part 31 is reduced, thereby reducing the heat generated by the first magnetic part 31, so as to extend the service life of the electromagnetic drive mechanism 30.

[0104] In some embodiments, step S203 is also included: after the controller 33 adjusts the AC power provided by the power supply device to the second frequency, the controller 33 obtains the second temperature of the coil 311. If the second temperature is less than or equal to the second preset temperature, the controller 33 controls the power supply device to adjust to the first frequency.

[0105] Specifically, after the controller 33 adjusts the AC power provided by the power supply device to the second frequency, the controller 33 obtains the second temperature of the coil 311 of the first magnetic member 31, and determines whether the second temperature is less than or equal to the second preset temperature. If so, the controller 33 controls the power supply device to adjust to the first frequency. By setting the second preset temperature, the electromagnetic drive mechanism 30 will not be in a reduced frequency state for a long time after the frequency is reduced, and the electromagnetic drive mechanism 30 returns to a high-frequency operation state after the second preset temperature is met. The second preset temperature is generally a safe temperature for the electromagnetic drive mechanism 30 to operate for a long time, and can be adjusted according to the characteristics of the electromagnetic drive mechanism 30, for example, it can be 80°C.

[0106] In some embodiments, in step S202, the controller 33 adjusts the AC power provided by the power supply device from the first frequency to the second frequency in a linear adjustment process, and the frequency reduction process is gradual through the linear adjustment, so that the frequency reduction process of the reciprocating motion of the second magnetic member 32 is also gradual. Linear adjustment means that the change value of the frequency in a unit time remains unchanged.
