[0025] In this embodiment, the model of the wireless transmission chip is IP6821.

[0026] In this embodiment, the model of the wireless receiving chip is COPO_CP2101.

[0027] In this embodiment, the electronic equipment includes at least an electronic door lock and an electronic peephole.

[0028] This application achieves contactless power transmission through electromagnetic induction or magnetic resonance. This design is particularly suitable for situations where continuous power supply is required and frequent battery replacement is difficult, such as electronic door locks.

[0029] Specifically, the power supply is a power adapter connected to the mains electricity supply, which converts the mains electricity into a safe low-voltage power source. The power supply is connected to the wireless charging transmitter control circuit via the power input interface. The wireless charging transmitter control circuit is connected to the transmitting antenna unit, which is mounted on the side of the door frame. The wireless charging transmitter control circuit converts low-voltage direct current into a high-frequency electromagnetic signal and transmits it outward through the transmitting antenna unit. The receiving antenna unit is connected to the wireless charging receiver control circuit, which is also mounted on the side of the door. The receiving antenna unit and the wireless charging receiver control circuit are used to receive the electromagnetic oscillation signal emitted by the wireless charging transmitter control circuit and transmit it to the power rectifier module. The power rectifier module rectifies the electrical energy generated by the received electromagnetic oscillation signal and outputs it to the power output interface. The power output interface is used to power the electronic lock, peephole, etc. installed on the door. When the door is closed, the transmitting antenna unit mounted on the side of the door frame aligns with the receiving antenna unit mounted on the side of the door, forming an electromagnetic coupling between the two. The distance between the two is less than 5 mm to ensure efficient energy transmission. The transmitting antenna unit generates an electromagnetic field through the wireless charging transmission control circuit, while the receiving antenna unit receives energy through electromagnetic induction. The energy received by the wireless charging reception control circuit is transmitted to the power rectifier module, which rectifies the energy into DC power and supplies it to the electronic door lock through the power output interface.

[0030] The contactless power supply reduces the failure rate caused by poor contact. Its continuous power supply eliminates the need for frequent battery replacement, reducing maintenance costs. It also reduces environmental pollution caused by discarded batteries and simplifies the wiring process, making installation easier.

[0031] The 220V AC mains power is converted to a 12V DC power supply. The wireless charging transmitter control circuit receives the 12V DC power supply and converts it into a high-frequency electromagnetic signal. The transmitting antenna unit transmits the high-frequency electromagnetic signal. The receiving antenna unit receives the electromagnetic signal from the transmitting antenna unit. The wireless charging receiver control circuit converts the received electromagnetic signal into electrical energy and outputs a 5V voltage. The charge and discharge management circuit charges the lithium battery and, when needed, boosts the lithium battery voltage to 5.5V for use by the door lock. The lithium battery stores electrical energy and provides power to the door lock when wireless transmission is interrupted. The boost circuit increases the lithium battery voltage to the required 5.5V to ensure proper operation of the door lock.

[0032] When the door is closed, the transmitting antenna unit and the receiving antenna unit are aligned, and the wireless charging transmission control circuit begins operating. The transmitting antenna unit transmits energy to the receiving antenna unit through an electromagnetic field. Once the receiving antenna unit receives the energy, the wireless charging reception control circuit converts the electromagnetic energy into electrical energy and outputs a 5V voltage. The charge and discharge management circuit then begins charging the lithium battery and boosts the voltage to 5.5V for use by the door lock.

[0033] When the door is opened, the transmitting and receiving antennas become misaligned, interrupting wireless energy transmission. At this point, the charge and discharge management circuit immediately switches to lithium battery power mode. The lithium battery outputs 5.5V through the boost circuit, continuing to power the door lock. When the door is closed again, the system re-enters wireless energy transmission mode. The transmitting and receiving antennas regain alignment, and the wireless charging and receiving control circuit resumes operation. The charge and discharge management circuit continues charging the lithium battery and boosts the voltage to 5.5V.

[0034] This application can ensure that when the door is closed, the efficiency of energy transmission is as high as possible, reducing energy loss. This application is also provided with a fast charging switching circuit, the purpose of which is a fast and reliable switching mechanism to ensure that the system can seamlessly switch from wireless power supply to lithium battery power supply at the moment the door is opened. The charge and discharge management circuit must have intelligent management functions to prevent overcharging or over-discharging of the lithium battery. Ensure that the entire system can operate stably under various conditions, especially when the door is frequently opened and closed. The smart door lock power supply system designed in this way can not only reduce the frequency of battery replacement and reduce maintenance costs, but also effectively avoid equipment failure problems caused by insufficient battery power. In addition, this system can also be extended to other smart devices that require continuous power supply, such as various sensors and controllers in smart homes.

[0035] The above description is only a preferred embodiment of the present invention and does not limit the patent scope of the present invention. All equivalent structural transformations made by using the contents of the present invention specification and drawings under the utility model concept, or direct / indirect application in other related technical fields are included in the patent protection scope of the present invention.
