Problems solved by technology

This not only wastes resources, increases the cost of products, but is not conducive to environmental protection.
The problem is that the charging device is not universal, and the charging device can only charge a certain type of electronic product. If the charging device does not match the electronic product, the charging device cannot identify the electronic product, nor can it identify the battery type. Adjust the power at which it charges, potentially damaging electronics
In addition, most of the existing charging devices are wired to charge electronic products. For users, charging is also troublesome.

Embodiment Construction

[0016] figure 1 It is shown that the present invention includes two parts: a power sending device 1 and a power receiving device 2 . Adjust the height position relationship between the air-core coil 11 and the air-core coil 21. When the distance between the two air-core pair air-core coils is 2-30 mm, the best coupling state can be achieved, which can make the charging efficiency of the device high.

[0017] figure 2 The structure of the present invention is shown. The power sending device and the power receiving device are described in detail respectively.

[0018] The power transmission device includes an air-core coil 11, a driver control unit 12, a drive unit 13, a control signal processing circuit 14, a detection unit (ID authentication, abnormal detection) 15, an RFID information transmission unit 16, and a current detection unit 17. When the device is plugged into an AC power source, the air-core coil 11 will not transmit power first, so that the power transmission ...

Abstract

The invention relates to a non-contact electrical energy transmission device, particularly a non-contact charging device between an electrical energy emission device and an electrical energy receiving device, so as to realize the information exchange between the electrical energy emission device and the electrical energy reception device. The technical proposal is as follows: the electrical energy emission device and the electrical energy receiving device carry out the electrical energy transmission through coupling two air core coils. Additionally, the device utilizes the RFID technique to realize the information exchange between the electrical energy emission device and the electrical energy receiving device. On one hand, the electrical energy emission device performs the identification of the electrical energy receiving device, that is, the ID identification; on the other hand, the information exchange of the charging state between the electrical energy emission device and the electrical energy reception device is realized, thereby realizing the real-time monitoring of the charging process. Therefore, the non-contact electrical energy transmission device ensures the safe and controllable electrical energy transmission.

Description

technical field [0001] The invention relates to a non-contact electric energy transmission device. Background technique [0002] With the rapid development of science and technology, there are more and more portable electronic products such as mobile phones, digital cameras, handheld computers, and PDAs. For electronic products of different types or different models of the same type, the power supply batteries are not uniform, so each electronic product has a matching charging device and is incompatible with each other. This has not only wasted resources, increased the cost of products, but also is not conducive to environmental protection. The problem is that the charging device is not universal, and the charging device can only charge a certain type of electronic product. If the charging device does not match the electronic product, the charging device cannot identify the electronic product, nor can it identify the battery type. Adjusting the power at which it charges ma...
