A wireless powered luminous puzzle as shown in
Specifically, in order to improve a seismic performance of the puzzle module, the present application proposes a puzzle module that utilizes an induction coil to achieve wireless illumination. In the puzzle module, multiple fixed hierarchical structures are included. The PVC board is provided below, and is used to provide support strength for the puzzle, the paper board in a middle is used to provide cushioning for the LED module, the TPE board provided above is used to print the pattern according to an actual pattern requirement, thereby providing relevant translucent lines to achieve the luminous purpose of the pattern. The interior LED module and the power supply circuit in the positioning base board sense each other. As the puzzle module does not contain a power supply, it can only emit light when the puzzle is placed on the positioning base board. In the present application, the LED module is embedded in the paper board, which can provide effective buffering protection for the LED module and provide a good fixation effect for the LED module, thereby avoiding a loosening of a component caused by collision. In the present application, electromagnetic induction power supply is used between the puzzle module and the positioning base plate below, which can avoid metal contact leakage and effectively protect the interior circuit.
In an implementation mode, as shown in
In an implementation mode, the power supply circuit includes a switch module for connecting to an external power source, a boost module for adjusting a power supply voltage of the circuit, a high frequency oscillation module, an amplification-and-transmission module, a second induction coil for inductive connection with the puzzle module, and an indicator light module for indicating a working state of the circuit; an output end of the switch module is connected to an input end of the boost module; an output end of the boost module is connected to a 12V voltage terminal; a first output end of the high frequency oscillation module is connected to an input end of the amplification-and-transmission module; an output end of the amplification-and-transmission module is connected to an input end of the second induction coil; a control end of the indicator light module is connected to a second output end of the high frequency oscillation module.
In the present application, the switch module is configured to connect with an external power source. The switch module can convert an input voltage into a stable 5V voltage terminal, then the boost module is used to convert the 5V voltage into a 12V voltage terminal. The high frequency oscillation module can generate an AC signal, a power of the AC signal is not enough to drive a load on the puzzle module to work after passing through the second induction coil. Therefore, the AC signal can only emit light through the second induction coil which drives the puzzle module after being amplified by the amplification-and-transmission module, as well as filtered and rectified.
In an implementation mode, as shown in

The first pin of the latch chip U1 is connected to a control signal. When the control signal is input at a high level, the latch chip U1 starts working, the indicator light module can control a conduction of the transistor when it receives the high level, thereby controlling a diode of the indicator light to emit light.
In an implementation mode, as shown in
The gate of the first MOS transistor Q101 in the amplification-and-transmission module receives an AC signal output from the high frequency oscillation module, a switching characteristic of the MOS transistor is used, when the input is low, the first MOS transistor Q101 is cut off, an voltage output from the 12V voltage terminal is directly filtered by multiple inductors and capacitors C, which is subjected on the fifteenth capacitor C15 and the sixteenth capacitor C16, causes a +12V voltage to be set on both the fifteenth capacitor C15 and the sixteenth capacitor C16, that is to render the output end outputs a high level; in a case of high input level, the first MOS transistor Q101 conducts, the drain and source electrode of the first MOS transistor Q101 are connected to each other. Charges in the fifteenth capacitor C and the sixteenth capacitor C16 are released through the first MOS transistor Q101 to output a low level at the output end. By alternating high and low levels, a driving current is provided to the second induction coil. After receiving the AC power, the second induction coil can drive the first induction coil to work through the electromagnetic induction principle.

A second pin of the voltage regulation chip U2 outputs a voltage of 12V after voltage regulation. A first transistor Q1 and the second transistor Q2 provide a safety function for the voltage regulation chip U2. When a fourth pin of the switch control chip U3 or a seventh pin of the switch control chip U3 outputs a low level, the first transistor Q1 is cut off, a level at the first pin of the voltage regulation chip U2 is high, when the first transistor Q1 or the second transistor Q2 is conductive, the level at the first pin of the voltage regulation chip U2 is low, which controls the voltage regulation chip U2 to stop working.
In an implementation mode, as shown in
In the present application, the switch control chip U3 adopts a model NY8A051FP8; a second and third pins of the switch control chip U3 are connected to an external control terminal through the connector J1.

The gate G is connected to the source S through a weak pull-up resistor R for startup. When the input VBUS voltage reaches a certain value, a voltage input to the sixth pin of the switch control chip U3 exceeds a predetermined voltage, the second MOS transistor Q102 conducts, and outputs a 5V voltage at the drain D.
In an implementation mode, as shown in

Compared with the luminous puzzle in existing technology, the present application effectively protects the PCB inside the puzzle module by embedding the LED module into the paper board of the puzzle module, improves a seismic performance of the puzzle module, avoids the loosening and damage of the LED module component. An energy transfer principle on the puzzle is changed from an original contact connection to coil induction energy transfer, which can avoid a short circuit of metal contacts and improve a lifespan of the puzzle.
