Description

A wireless charger

technical field

The utility model relates to the technical field of wireless charging, in particular to a wireless charger.

Background technique

A wireless charger refers to a charger that is connected to a terminal device that needs to be charged without a traditional charging power cord. It adopts the latest wireless charging technology. The wireless charging technology obtained 20 patents in 2007. A variety of devices can use one Charging base stations, wired charging for cell phones, MP3 players, power tools and other power adapters will no longer exist. By using the magnetic field generated between the coils to magically transmit electrical energy, inductive coupling technology will become a bridge connecting charging base stations and devices. Most current chargers, such as iPads and iPhones, charge the device's built-in battery through direct contact with metal wires. The advantage of wireless charging technology lies in its convenience and versatility. The disadvantage is low efficiency and can only provide electric energy. Apple's Dock connector not only provides power, but also syncs audio and video files to the device via the USB interface. However, wireless charging technology will still bring improvements to WiFi and battery technology. For devices that do not require data transmission, this new technology will greatly reduce the number of various chargers that users need. In addition, through the adoption of wireless charging technology, public mobile device charging stations will become a reality.

Traditional wireless chargers have high requirements for the user's mobile phone model. When the user's mobile phone model does not match, wireless charging cannot be performed, which greatly limits the user's wireless charging.

Utility model content

In order to achieve the above purpose, the utility model adopts the following technical scheme: a wireless charger, including a wireless charger power supply, a power transmitting coil and a power receiving coil, and an external power cord is nested and installed on the lower right side of the wireless charger power supply , and a plug is fixedly installed on the left side of the external power cord, an output power cord is nested and installed on the upper right side of the wireless charger power supply, and a power transmission coil is fixedly installed on the right side of the output power cord, and the power transmission coil The lower left is nested with a transmitting signal line, and the output end of the transmitting signal line is fixedly installed with a transmitting device, and the output end of the receiving device is electrically connected to the input end of the receiving coil through the receiving signal line.

As a further description of the above technical solution:

The output end of the power receiving coil is electrically connected to the input end of the multifunctional USB interface through the input power line.

As a further description of the above technical solution:

The input end of the transmitting device is electrically connected with the output end of the power transmission coil.

As a further description of the above technical solution:

There is a detachable structure between the multifunctional USB interface and the power receiving coil.

In the utility model, the new wireless charger divides the overall structure into two parts, which are respectively the wireless charger power supply part and the wireless power receiving device. Users can choose different mobile phone models according to their own mobile phone models in the process of using the wireless charger. The wireless charging method makes the wireless charger more widely applicable. At the same time, the new wireless charger uses the principle of electromagnetic induction to convert the mains power into an electromagnetic field. When the user enters the laying range of the wireless charger power transmission coil, the mobile phone can Automatic wireless charging greatly eliminates the need for power supply for wired charging, making users' work and life more efficient.
