In order to better understand the present invention, the following explains it from another point of view.
The invention provides a plug-free storage device based on a wireless energy transfer technology, which mainly comprises a Bluetooth unit, a storage unit and a wireless energy transfer unit.
The bluetooth unit comprises the bluetooth chip 33 and a first PCB 34. The bluetooth unit is fixed on the receiving end PCB 37 and is used for data transmission with the host 1 and data reading and writing with the storage unit.

The power supply control assembly comprises the inverter 22, the relay 23 and the wireless energy transmission controller, and all the devices are connected through conducting wires. The wireless energy transfer system is connected with direct current from the power supply of the host 1, outputs high-frequency alternating current after passing through the inverter 22, the output end of the inverter 22 is connected with the transmitting coil 21 through the relay 23, and controls the on-off state of the relay 23 through the wireless energy transfer controller to control the on-off of the current of the transmitting coil 21.
The power supply control assembly further comprises the rectifier 32, the front stage of the rectifier 32 is connected with the receiving coil 31, and the rectifier 32 converts the high-frequency alternating current in the receiving coil 31 into direct current to supply power to the Bluetooth unit and the storage unit.
In a preferred embodiment, the power supply control assembly further includes the coil identification monitoring module 25, configured to send a radio frequency signal, and implement contactless wireless data communication between the transmitting circuit and the receiving circuit through coupling, so as to obtain electronic tag information of a target receiving circuit (i.e., the second assembly 3), and further control the transmitting circuit (i.e., the first assembly 2) to adjust output power, thereby implementing wireless charging of different electronic devices.
The power supply control assembly is defaulted to work in a low-power supply strategy which meets the work of the plug-in and pull-out-free storage device, and the whole power supply control assembly is in a low-power consumption standby state. When the plug-in free storage device is accessed, the coil identification monitoring module 25 acquires the electronic tag information of the receiving circuit, and the power supply control assembly supplies power to the plug-in free storage device according to a default low-power supply strategy; when other electronic devices are connected, the coil identification monitoring module 25 acquires the electronic tag information of the receiving circuit, and controls the power supply control assembly to adjust the output power, so that the charging requirements of other electronic devices are met.
The Bluetooth unit adopts a low-power Bluetooth communication module, can realize a Bluetooth 5.0 protocol, is used for data reading and writing with the storage unit and data receiving and broadcasting with the host 1, and supports the highest data transmission rate of 2 Mb/s.
The main control chip 35 of the storage unit is used for reading and sending data between the bluetooth unit and the flash memory particles 36; the flash memory granule 36 is used for storage of data.
In practical applications, the emitter support plate 24 may be mounted on the top of the host 1, i.e. the first component 2 is mounted on the top surface of the host 1. Furthermore, the second component 3 may be placed directly on the top surface of the first component 2. When the bluetooth function of the host 1 is turned on and the second component 3 is disposed in the sensing area of the first component 2, the coil identification monitoring module 25 generates current through magnetic induction and converts the current into a signal with a special frequency, the tag circuit 38 in the second component 3 receives the microwave signal transmitted by the coil identification monitoring module 25 and obtains energy through the receiving coil 31 to supply power to the tag circuit for a short time, and simultaneously generates a radio frequency signal to respond, and the coil identification monitoring module 25 identifies the identity of the power supply device to complete the information exchange. After the target is confirmed, the inverter 22 converts the direct current of the power supply of the main unit 1 into a high-frequency alternating current, and supplies power to the transmitting coil 21 through the relay 23 in an on state. The processed high-frequency alternating current is obtained from the transmitting coil 21, and the frequency of the receiving coil 31 is the same as that of the transmitting coil 21, so that the transmitting coil 21 and the receiving coil resonate, the current in the receiving coil 31 is processed by the rectifier 32 to obtain direct current with a certain amplitude, the direct current respectively supplies power to the bluetooth chip 33 and the main control chip 35, at the moment, the bluetooth chip 33 and the main control chip 35 are both in a working state, and data transmission can be performed after the bluetooth matching with the host 1 is completed, so that the function of the plug-and-play-free storage device is realized.
When the object identified by the coil identification monitoring module 25 (i.e., the second component 3) is other electronic equipment such as a mobile phone with a wireless charging function, the coil identification monitoring module 25 identifies the tag circuit 38 inside the electronic equipment according to the above procedure, and after information exchange is completed, controls the power supply control component of the wireless energy transfer unit to adjust the original power supply strategy so as to meet the charging requirements of different electronic equipment.
