Multi-load self-detection three-dimensional wireless power supply system and method

Abstract

The invention belongs to the field of wireless power supply, and particularly relates to a multi-load self-detection three-dimensional wireless power supply system and method. The multi-load self-detection three-dimensional wireless power supply system comprises a transmitting device located in a three-dimensional space and a receiving device located on loads, wherein the transmitting device comprises a signal processor, an information receiving / transmitting terminal, DC / AC, a PFC and a resonant transmitting terminal; the information receiving / transmitting terminal and the DC / AC carry out data exchange with the signal processor separately; the PFC and the resonant transmitting terminal are connected with the DC / AC separately; the receiving device comprises a charging mode providing processor, a resonant receiving terminal, an information transmitting / receiving terminal and AC / DC connected with the resonant receiving terminal; the resonant receiving terminal and the information transmitting / receiving terminal are connected with the charging mode providing processor separately; the resonant transmitting terminal communicates with the resonant receiving terminal through a resonant frequency; and data interaction is carried out between the information receiving / transmitting terminal and the information transmitting / receiving terminal. The connection state of the loads in the three-dimensional space is automatically detected, the loads are automatically matched and the frequency of the transmitting terminal is automatically adjusted, so that power transmission in the three-dimensional space is achieved.

Description

technical field [0001] The invention belongs to the field of wireless power supply, in particular to a multi-load self-detection three-dimensional wireless power supply system and method. Background technique [0002] The world has entered the digital age, and various digital electronic products such as mobile phones, computers, cameras, smart wearable devices, and virtual reality devices are flooding people's lives, and current electronic products are increasingly pursuing light, thin, short, and small design concepts. A very important factor affecting the appearance of the product volume is the design of the battery system. [0003] Most electronic products currently on the market use a rechargeable battery installed in the electronic product, and then charge the rechargeable battery through an external charger when charging. This charging method has the following disadvantages: [0004] 1. The user needs to carry the charger with him, which not only brings inconvenience...

AI Technical Summary

Problems solved by technology

[0004] 1. The user needs to carry the charger with him, which not only brings inconvenience to the user but also takes up space;

[0005] 2. The interface of the charger is not uniform. For example, the interface standards of Android and Apple devices are different. Using two different electronic products requires the purchase of multiple different chargers, which wastes resources;

[0006] 3. A charger can only charge one device, not multiple devices at the same time

[0008] 1. The transmitting end of wireless power transmission can only perform one-to-one energy transmission of a single frequency, and the universal applicability of the product is poor;

[0009] 2. The transmitter still has a large power consumption in the case of no energy transmission, which will cause energy waste;

[0010] 3. The receiving end cannot automatically adjust and match the transmission power of the external transmitting end. When the transmitting end changes or the transmission distance changes, it will greatly affect the efficiency of energy transmission
