Problems solved by technology

However, the disadvantages of this scheme are: firstly, the wireless power receiver adopts an external type, which affects the convenience; secondly, in order to increase the transmission distance and power of electric energy, a Magnetic core, the weight of the magnetic core is heavy and inflexible, which increases the weight and volume of the charger
These two aspects undoubtedly make the application of this technology in notebooks greatly reduced

Abstract

A wireless charging device for laptops relates to wireless charging. The wireless charging device for laptops is smaller and lighter, and is flexible. A receiving coil can be either installed outside the bottom of a laptop or built in the laptop at design time. The wireless charging device comprises a high-frequency power supply, an electric energy transmitting coil, an electric energy receiving coil, and a post-processing circuit. DC power is connected to the input end of the high-frequency power supply. The two pins of the electric energy transmitting coil are connected with the output end of the high-frequency power supply. The two pins of the electric energy receiving coil are connected with the input end of the post-processing circuit. The output end of the post-processing circuit is connected with the charging port of a laptop.

Description

technical field [0001] The invention relates to wireless charging, in particular to a wireless charging device for notebook computers. Background technique [0002] Notebooks have become the best choice for mobile office because of their strong functions, small size, and portability. The battery capacity of today's mainstream notebooks can only last for several hours of work. Before the battery technology has made a major breakthrough, To prolong the working hours of the laptop, it can only be charged frequently. [0003] At present, almost all laptops are equipped with power adapters for charging, but the traditional method is to use wires for charging, which not only limits the range of activities of the user, but also frequently plugs and unplugs the connectors often leads to poor contact and affects use. Wireless charging technology can solve this problem very well and greatly improve the user experience, as long as the notebook with wireless charging function is close ...
