[0027] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below in conjunction with the accompanying drawings.

[0028] In the following description, many specific details are set forth to facilitate a full understanding of the present invention, but the present invention may also be implemented in other ways different from those described herein, and those skilled in the art may make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0029] Secondly, the term "one embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The term "in one embodiment" that appears in different places in this specification does not necessarily refer to the same embodiment, nor does it refer to a separate or selective embodiment that is mutually exclusive with other embodiments.

[0030] Example 1, reference Figure 1 and Figure 2 , which is the first embodiment of the present invention, and this embodiment provides a wireless charging self-luminous device, including a storage lining 100, including n wireless charging stations 101, wherein n is a natural number greater than or equal to 1; a charging unit 200, including n wireless charging circuits 201 and wireless luminous devices 202, the wireless charging circuits 201 correspond one-to-one to the wireless charging stations 101, and the wireless luminous devices 202 can be placed in the wireless charging stations 101 and receive electrical energy from the wireless charging circuits 201.

[0031] The storage liner 100 is also provided with n permanent magnet built-in stations 102, where n is a natural number greater than or equal to 1; the wireless charging stations 101 correspond to the permanent magnet built-in stations 102 one by one;

[0032] An eccentric structural column 103 is provided at a non-center portion of the wireless charging station 101 close to the permanent magnet built-in station 102 .

[0033] Among them, the eccentric structural column 103 can ensure that the position of the wireless light-emitting device when placed on the wireless charging station 101 is unique, and further ensure that the spatial position of the double-station reed switch of the wireless light-emitting device uniquely corresponds to the built-in station of the permanent magnet, thereby ensuring that the permanent magnet and the double-station reed switch fit tightly and work correctly, and also ensure that the spatial position of the receiving coil of the wireless charging light-emitting device uniquely corresponds to the transmitting coil of the wireless charging circuit, thereby ensuring that the receiving coil of the wireless charging light-emitting device fits tightly with the transmitting coil of the wireless charging circuit, reducing the loss during energy transfer.

[0034] The eccentric setting of the eccentric structural column 103 ensures that the permanent magnet at a certain station has the sole control over the double-station reed switch, that is, it will not be interfered by other stations.

[0035] Example 2, reference Figure 2 , which is the second embodiment of the present invention, and provides a wireless charging circuit 201, including a power distribution module 201a, the power distribution module 201a reduces the voltage of 220V mains power and transmits it to n transmitting end circuits 201b, wherein n is a natural number greater than or equal to 1;

[0036] The transmitting end circuit 201 b corresponds one to one with the wireless charging station 101 .

[0037] The design of the power distribution module 201a includes the following optimizations: Multiple outputs: The power distribution module 201a can be designed with multiple outputs to meet the needs of different numbers of wireless charging stations 101. Each output path can be independently controlled to improve the flexibility and reliability of the system; Power factor correction (PFC): In order to improve energy efficiency, the power distribution module can integrate a power factor correction circuit to reduce harmonic pollution in the power grid; Overload protection: The module should have an overload protection function. When the load exceeds the design value, it can automatically cut off the power supply or reduce the output power to protect the circuit safety.

[0038] Optimization of the transmitter circuit 201b: Frequency modulation and voltage regulation technology: The transmitter circuit can dynamically adjust the transmission frequency and voltage according to the charging status of the receiver to achieve optimal charging efficiency; Multi-coil design: In order to cover a larger charging area, the transmitter circuit can adopt a multiple coil design to achieve a more flexible charging area configuration through phase control; Foreign object detection: The transmitter circuit can integrate a foreign object detection function, and when a metal foreign object is detected, it automatically reduces the power or stops charging to prevent overheating and potential safety risks.

[0039] Example 3, reference Figure 3 , which is the third embodiment of the present invention, and provides the specific principle of the transmitting end circuit 201b, including an oscillating circuit and a power amplifier circuit;

[0040] The oscillation circuit includes a fourth capacitor C4, an inductor L3, and a transmitting end coil L2. The transmitting end coil L2 emits high-frequency alternating current to the outside. The fourth capacitor C4 and the inductor L3 form a resonant loop of the oscillation circuit.

[0041] The power amplifier circuit includes a first power transistor Q1 and a second power transistor Q2, and the power amplifier circuit amplifies the signal power from the oscillation circuit.

[0042] In the oscillator circuit, the fourth capacitor (C4) and the inductor (L3) have the following functions:

[0043] 1. Resonance: The fourth capacitor C4 and the inductor L3 together form the resonant loop of the oscillation circuit, which determines the resonant frequency of the circuit. In the LC oscillator, the oscillation frequency is determined by the inductor L and the capacitor C value, and the formula is This frequency is the natural frequency of electromagnetic energy exchange in the circuit and is also one of the conditions for the circuit to maintain oscillation.

[0044] 2. Frequency selection: The fourth capacitor C4 and the inductor L3 play a frequency selection role in the circuit. They allow signals of a specific frequency to pass through, while blocking signals of other frequencies. This frequency selection characteristic is very important for the oscillation circuit because it ensures that the circuit can generate an oscillation signal of a specific frequency.

[0045] 3. Positive feedback: In the oscillation circuit, the fourth capacitor C4 and the inductor L3 also participate in forming a positive feedback path. Positive feedback is the key to the continuous oscillation of the oscillation circuit, which feeds back part of the circuit output to the input end to maintain the oscillation.

[0046] 4. Impedance matching: Inductor L3 can also play the role of impedance matching in the circuit. It helps to adjust the input and output impedance of the circuit to adapt to different load conditions.

[0047] 5. Filtering function: The fourth capacitor C4 can be used as a high-frequency bypass capacitor, which allows high-frequency signals to pass through while blocking low-frequency signals or DC components, which helps to filter out unnecessary signal components and ensure the purity of the oscillation signal.

[0048] In summary, the fourth capacitor C4 and the inductor L3 play multiple roles in the oscillation circuit, including resonance, frequency selection, positive feedback, impedance matching and filtering, and are key components for the oscillation circuit to work normally and generate an oscillation signal of a specific frequency.

[0049] Example 4, reference Figure 4 and Figure 5 , which is the fourth embodiment of the present invention, and this embodiment provides a specific structure of a wireless light-emitting device 202, which can be a square structure and match the wireless charging station 101;

[0050] A tether hole 202 a is passed through the non-center portion of the wireless light emitting device 202 , and the tether hole 202 a has the same diameter as the eccentric structural column 103 .

[0051] The wireless light-emitting device 202 is formed by solidifying an integrated transparent epoxy resin, and has the advantages of strong light transmittance, high structural strength, wear resistance, and corrosion resistance.

[0052] The tether hole 202a here has two uses. In addition to ensuring the uniform position of the receiving coil L1, the transmitting coil L2, the permanent magnet, etc. during charging, it can also be used to pass the hanging rope, specifically to provide reliable lighting when transporting objects to high places.

[0053] Example 5, reference Figure 6 , which is the fifth embodiment of the present invention, and which provides

[0054] The wireless lighting device 202 has a built-in receiving coil L1, which receives the alternating magnetic field from the transmitting coil L2 and generates alternating current, which is converted into direct current through a bridge and supplies power to the battery BAT1 through one position of the double-position reed switch SW1.

[0055] The receiving coil L1 is connected to the bridge after being filtered by the first capacitor C1, and the bridge is connected in parallel with the second capacitor C2 and the third capacitor C3.

[0056] When the wireless light-emitting device 202 is placed in the wireless charging station 101, the double-station reed switch SW1 is controlled by the permanent magnet built-in station 102 so that the double-station reed switch SW1 is connected to the receiving coil L1;

[0057] The bridge of this embodiment is composed of four diodes D1-D4, i.e., a rectifier bridge, which is a circuit that converts alternating current (AC) into direct current (DC). The rectifier bridge can be a full-wave rectifier bridge or a half-wave rectifier bridge, but the most common is the full-wave rectifier bridge because it can extract energy from both the positive and negative half cycles of the alternating current.

[0058] Working principle of full-wave rectifier bridge: AC input: When AC power is input to the rectifier bridge, it has voltage in both positive and negative directions in each half cycle.

[0059] Diodes Conduct: During the positive half cycle of AC, current flows through diodes D1 and D3 because they are forward biased (anode voltage is higher than cathode voltage). During the negative half cycle, current flows through diodes D2 and D4 because they are forward biased.

[0060] Current flow direction: In the positive half cycle, the current starts from the positive pole of the AC power supply, passes through D1, flows into the load, and then returns to the negative pole of the power supply through D3. In the negative half cycle, the current starts from the negative pole of the power supply, passes through D2, flows into the load, and then returns to the positive pole of the power supply through D4.

[0061] DC output: Due to the action of the rectifier bridge, the load obtains pulsating DC power, that is, the direction of the current remains unchanged, but the current magnitude changes with the periodic changes of the AC power.

[0062] Filtering: In order to obtain smoother DC power, a filter (such as a capacitor) is usually added after the rectifier bridge to reduce the ripple of the output voltage.

[0063] Working principle of half-wave rectifier bridge: Unidirectional conduction: In half-wave rectification, current will flow through a diode (such as D1) only when the alternating current is in the positive half cycle, and the current is blocked during the negative half cycle.

[0064] DC output: The DC power obtained in this way is unidirectional, that is, only the positive half-cycle voltage is rectified and the negative half-cycle is ignored.

[0065] A full-wave rectifier bridge is more efficient than a half-wave rectifier bridge because it utilizes both half cycles of the AC power, thereby increasing the utilization of the power. Rectifier bridges are widely used in power adapters, power supplies, and battery chargers to convert AC power to the DC power required by electronic devices.

[0066] Example 7, reference Figure 7 and Figure 8, which is the sixth embodiment of the present invention, and this embodiment provides a working mode of a double-station reed switch SW1, and the other station of the double-station reed switch SW1 is also connected to the battery BAT1 through the light-emitting diode D5 and the current-limiting resistor R1. When the wireless light-emitting device 202 leaves the wireless charging station 101, the station of the double-station reed switch SW1 is connected to the light-emitting diode D5.

[0067] At this time, the battery BAT1 supplies power to the light-emitting diode D5, that is, when the wireless light-emitting device 202 leaves the wireless charging station 101, it needs to be used in conjunction with the hanging rope when working at a high place on the pole.

[0068] Example 6, reference Figure 7 and Figure 8 , which is the sixth embodiment of the present invention, and this embodiment provides a wireless charging storage box, including the wireless charging self-luminous device of the above embodiment, including a box unit 300, in which a wireless charging circuit 201 and a storage lining 100 are placed, and the box unit 300 is connected to a 220V AC power supply through a charging cable.

[0069] The box unit 300 includes a box body and a box cover, and is portable.
