[0066] This invention includes a magnetic levitation display device that automatically identifies the identity information of suspended objects, such as... Figure 1 As shown, it includes a suspension part 1 and a driving part 2. The suspension part 1 includes:

[0067] Suspended solids 101;

[0070] The first magnet module 104 (the first magnet module and the information transmission module are integrated, Figure 1 which is not shown in the figure) is arranged on the levitron 101.

[0071] The driving part 2 comprises:

[0072] The information receiving module 201 comprises a signal demodulation circuit 2011 and is arranged in a driving base and is in bidirectional communication connection with the information transmission module 103, and is used for receiving and demodulating the identity information.

[0073] The control module 202 is connected with the output end of the information receiving module and is used for identifying the identity information after the demodulation.

[0074] The second magnet module 203 is connected with the first output end of the control module 202, and the control module 202 controls the second magnet module 203 to be powered after identifying the identity information, so that the bottom of the levitron 101 is suspended above the driving base under the repulsion of the first magnet module 104 and the second magnet module 203.

[0075] Specifically, the levitron 101 in the embodiment is taken as a doll as an example, and the levitron can also be other objects. After the doll with the information storage module 102 is placed on the driving base, the information transmission module 103 modulates and transmits the identity information of the doll to the information receiving module 201 in the driving base, the information receiving module 201 demodulates and transmits to the control module 202, and the control module 202 identifies the identity information of the doll and inputs control current to the second magnet module 203, so that the magnetic levitation display device is started and the doll is in a suspended state. After the doll is removed, the control module 202 stops supplying power to the second magnet module 203, the magnetic levitation display device is closed, and the doll is out of the suspended state.

Figure 4 The input end of the driving motor B1 is connected to the output end of the third chip.

[0077] Specifically, the lifting driving module 204 is arranged below the second magnet module 203, and is used to drive the second magnet module 203 to move up and down under the control of the control module 202. When the magnetic levitation display device is started, the driving motor of the lifting driving module 204 drives the second magnet module 203 to move upward by a certain distance, so that the doll rises to a certain height and is in a levitation state. When the magnetic levitation display device is turned off, the driving motor of the lifting driving module 204 drives the second magnet module 203 to move downward by a certain distance, so that the doll descends and is out of the levitation state.

[0078] As a preferred embodiment, the magnetic levitation display device further comprises a communication module 205, the input end of the communication module 205 is connected to the third output end of the control module 202, and the control module 202 transmits the recognized identity information to the control terminal through the communication module 205. In this embodiment, the communication module 205 preferably adopts an RS485 communication circuit, and the control terminal is connected through the RS485 communication circuit. The control terminal can be an electronic device such as a mobile phone or a tablet computer or a computer. The user can view the identity information of the doll and the story related to the doll through the above-mentioned electronic device, so as to facilitate the user to understand more associated information of the doll, thereby bringing better display effect.

[0079] As a preferred embodiment, the magnetic levitation display device further comprises an information display module, the information display module comprises a voice broadcast device and / or a projection device.

The voice broadcast device can adopt a loudspeaker, so that the user can not only watch the doll, but also hear the doll story played by the loudspeaker.

[0080] As a preferred embodiment, the first magnet module 104 comprises a plurality of float magnets. As shown in the figure, Figure 10 The first magnet module 104 comprises a small magnet 1041, an iron block 1042, and a permanent magnet 1043. As shown in the figure, Figure 11As shown, the second magnet module 203 includes: a plurality of electromagnets 2031; a permanent magnet 2032, which is annularly arranged outside the plurality of electromagnets 2031, and is used to provide repulsion to the first magnet module 104; a plurality of Hall sensors 2033, which are correspondingly arranged on the plurality of electromagnets 2031, and are used to detect the deviation distance between the plurality of electromagnets 2031 and the float magnet of the first magnet module 104; an operational amplifier driving module 2034 Figure 1 As shown, the input end of the operational amplifier driving module 2034 is connected to the output end of the Hall sensor 2033, and the output end thereof is connected to the electromagnet 2031, which is used to control the repulsion of the plurality of electromagnets 2031 according to the deviation distance. As shown, Figure 8 In this embodiment, the magnetic suspension part includes one permanent magnet, four electromagnets, a Hall sensor, and an operational amplifier linear driving circuit. The permanent magnet is annularly arranged outside the four electromagnets. The permanent magnet provides upward repulsion to the first magnet module in the suspension part, and the four Hall sensors detect the tilt position of the float magnet and balance the float magnet through the operational amplifier driving module to ensure that the float magnet can be stably suspended.

[0081] Specifically, the magnetic suspension technology (electromagnetic levitation, electromagnetic suspension, referred to as EML technology or EMS technology) refers to a technology of using magnetic force to overcome gravity to suspend an object. Assuming that the first magnet module is disturbed downward at a reference position, it will deviate from the reference position. At this time, the Hall sensor detects the displacement of the first magnet module deviating from the reference point, the control module converts the detected deviation distance into a control signal, and then the power amplifier converts the control signal into a control current, which generates a magnetic force in the electromagnet of the second magnet module, thereby driving the first magnet module to return to the original equilibrium position. Therefore, no matter whether the first magnet module is disturbed downward or upward, the first magnet module can always be in a stable equilibrium state.

[0082] As a preferred embodiment, as shown, Figure 10 As shown, the information storage module 102 and the information transmission module 103 are connected through two spring probes 105, which are preferably pogo pin connectors. The suspension part further includes an upper shell 106, a lower shell 107, a tray upper shell 108, an RX coil 109, a coil fixing plate 110, a decorative part 111, a tray lower shell 112, and a silica gel foot pad 113.

[0083] As a preferred embodiment, as shown, Figure 2As shown, the information transmitting module specifically comprises: a first chip U1 comprising a plurality of pins; a first coil L1 connected to a first pin of the first chip through a first capacitor C1 and a first rectifier bridge D1, for supplying power to the first chip; a voltage stabilizing diode D2 connected between the first pin of the first chip and a ground terminal, for controlling the input voltage of the first chip; a first switch tube Q1, a gate of the first switch tube connected to a second pin of the first chip, a drain of the first switch tube connected between the first capacitor and the first rectifier bridge, and a source of the first switch tube grounded; a second switch tube Q2, a gate of the second switch tube connected to a third pin of the first chip, a drain of the second switch tube connected between the first coil and the first rectifier bridge, and a source of the second switch tube grounded. The information transmitting module further comprises capacitors C2, C3, C4 and C5, and resistors R1 and R2.

[0084] Specifically, the identity information corresponding to the doll is written into the ROM (read only memory image) inside the wireless RX MCU chip. When the RX detects the TX power signal transmitted by the second coil of the information receiving module through L1 and C1 resonance, the signal is rectified into a direct current power supply for U1 chip, D2 limits the voltage within the safe range of U1 chip, and U1 drives Q1 / Q2 to modulate the identity information of the doll to the power loop through PWM1 / PWM2 output port within 300mS, and transmits the information to the TX coil end through the coil L1.

[0085] As a preferred embodiment, as shown in Figure 4 As shown, the control module comprises a second chip U2, a pin 1 of the second chip U2 connected to a power supply terminal, pins 2, 3, 4 and 5 of U2 connected to Q3, Q4, Q5 and Q6 respectively, pins 6, 7, 8 and 9 of U2 used for connecting a communication module, pin 10 of U2 used for connecting a suspension switch circuit, pins 11 and 12 of U2 used for connecting a lifting drive module, and pin 13 of U2 used for connecting an information receiving module. As shown in Figure 3 As shown, the information receiving module specifically comprises: a second coil L2; a third switch tube Q3, a gate of the third switch tube connected to a second pin of the second chip, a drain of the third switch tube connected to the second coil L2, and a source of the third switch tube connected to the power supply terminal; a fourth switch tube Q4, a gate of the fourth switch tube connected to a fourth pin of the second chip, a drain of the fourth switch tube connected to the second coil, and a source of the fourth switch tube connected to the power supply terminal; a fifth switch tube Q5, a gate of the fifth switch tube connected to a third pin of the second chip, a drain of the fifth switch tube connected to the second coil, and a source of the fifth switch tube grounded; and a sixth switch tube Q6, a gate of the sixth switch tube connected to a fifth pin of the second chip, a drain of the sixth switch tube connected to the second coil, and a source of the third switch tube grounded.

[0086] Specifically, the second chip U2 outputs four PWM signals (PWM1 / PWM2 / PWM3 / PWM4), which are converted from DC power (VCC) to AC power by four MOSFETs (Q3 / Q4 / Q5 / Q6) and then transmitted by the L2 coil. At the node between L2 and C6, the signal is rectified by D3, and then bandpass filtered and decoded by R3 / R5 / R4 / C9 / C7 / C8. The doll's identity information is then obtained by PA8 of U2. The second chip U2 uses a floating switch circuit (…). Figure 6 (As shown) The seventh switch Q7 is turned on to activate the electromagnet of the second magnet module 203; the doll's identity information is sent out through the communication module; and the motor of the lifting drive module is activated to push the second magnet module 203 upward, so that the repulsive force of the second magnet module 203 suspends the doll and lifts it up. In this embodiment, the second chip U2 emits a power signal every 2 seconds and detects whether the doll responds with its identity information. If no identity information is received from the doll, the levitation system is turned off or not activated. Therefore, the drive base does not need to work continuously when in standby mode, reducing standby power consumption.

[0087] Through the above technical solution, the information transmitting module and the information receiving module in this embodiment adopt a wireless information transmission and reception method, and the TX coil in the information receiving module can wirelessly power the RX coil in the information transmitting module, so that the suspended part does not need to add a power source.

The lifting driving module 204 is arranged below the second magnet module 203 and is used to drive the second magnet module 203 to move up and down under the control of the control module 202. When the magnetic levitation display device is started, the driving motor of the lifting driving module 204 drives the second magnet module 203 to move upward by a certain distance, so that the doll ascends by a certain height and is in a levitation state; when the magnetic levitation display device is turned off, the driving motor of the lifting driving module 204 drives the second magnet module 203 to move downward by a certain distance, so that the doll descends and is out of the levitation state.
