Description

Wireless power supply wall

The present invention relates to a wireless power supply device, and more particularly to a wireless power supply wall. Background technique

Due to the advancement of electronic technology, there are more and more home appliances in the home. General household electrical appliances can be divided into rechargeable and non-rechargeable. For every period of use, rechargeable household electrical appliances must be connected to a charger for charging. The power plug is electrically connected to an external power source, and the non-rechargeable home appliance directly connects the power plug to an external power source. For non-rechargeable home appliances, the location must be adjacent to the external power supply, otherwise the user must use an extension cable to connect the non-rechargeable home appliance to the external power supply. Such a connection would allow the user to worry about the configuration of the extension cord and the security issues.

With this, the idea of wireless power supply came into being. At present, a wireless power supply technology using magnetic coupling resonance for power transmission is proposed, which uses non-radiative magnetic coupling, that is, two resonant objects of the same frequency to generate strong mutual coupling, and a single layer coil is used to form a common The resonant circuit does not emit electromagnetic waves, reducing energy waste. When using a coil wound with 5 turns of thick copper wire as the antenna, the efficiency is about 40% when the transmission is 2 meters, and the efficiency can be as high as about 90% when the distance is 1 meter. It will be a widely used wireless power supply technology. .

When the wireless power supply system is normally powered, the location of the wireless power supply coil and the wireless receiving coil is generally required. The relationship must be as parallel as each other.

However, nowadays, there are still a series of problems to be solved in the application of the above wireless power supply system in electronic devices such as televisions. For example, during installation, the wireless power transmitting end usually needs to be fixed on the wall of the house or embedded in the wall of the house. Therefore, the installation and movement of the wireless power supply module is troublesome. . In addition, the wireless power transmitter usually has a certain power supply, so it can only supply power to a certain power electronic device, and the function is relatively simple.
