Description

electronic device

Technical field:

The invention relates to an electronic device, and in particular to an electronic device with a charging function.

Background technique:

Although the efficiency of wireless charging is low, due to the small power consumption of the handheld device, its battery capacity and charging requirements are also small, so wireless charging can still meet the charging requirements of the handheld device.

The current wireless charging technology uses electromagnetic conversion to charge the charging terminal to the handheld device. Since the charging method is to transfer energy by magnetic energy, the energy can also be transferred through the shell between the devices. However, the above-mentioned method is still limited by the fact that the transmission of magnetic energy decays rapidly with the increase of the transmission distance. In addition, when performing wireless charging, the position between the main charging end and the handheld device needs to be aligned as much as possible to improve the transmission of magnetic energy. A common method to improve alignment accuracy is, for example, to use a mechanism that is fully compatible with the handheld device to restrict the handheld device to a specific direction of the main charging end, so that the charging function can be normal and efficient, such as an electric toothbrush.

It can be seen from the above that although wireless charging is very convenient, it still requires a specific main charging terminal during charging, and a suitable converter is also required for the handheld device. As a result, when the environment cannot provide enough main charging configurations to satisfy any user, the user must always carry the main charging terminal, which causes inconvenience to the user.
