Combined magnetic adsorption type wireless charger

Abstract

The invention discloses a combined magnetic adsorption type wireless charger, and relates to the technical field of charger equipment. The combined magnetic adsorption type wireless charger comprises a shell and a top cover, the top cover is arranged on the surface of the top of the shell, a limiting groove is formed in the middle of the surface of the bottom of an inner cavity of the shell, a release coil is arranged in an inner cavity of the limiting groove, and a micro-control panel is arranged on one side of the inner cavity of the shell. A release coil is arranged in the inner cavity of the shell, a lithium battery is arranged at the position, located above the release coil, of the inner cavity of the shell, an extension assembly is arranged on one side wall of the shell and comprises a placement box, a power transmission line is arranged in the inner cavity of the placement box, and one end of the power transmission line is electrically connected with the micro-control panel. The wireless charger can be used for wireless charging and wired charging, so that the use functionality of the wireless charger can be improved, heat dissipation treatment can be carried out on the wireless charger and equipment needing to be charged, and the safety of the equipment during charging is improved.

Description

technical field [0001] The invention relates to the technical field of charger equipment, in particular to a combined magnetic adsorption wireless charger. Background technique [0002] The wireless charger is a device that uses the principle of electromagnetic induction for charging. Its principle is similar to that of a transformer. By placing a coil at the sending and receiving ends, the coil at the sending end sends an electromagnetic signal to the outside under the action of electricity, and the coil at the receiving end receives the electromagnetic signal. Signal and convert the electromagnetic signal into electric current, so as to achieve the purpose of wireless charging. Wireless charging technology is a special power supply method, which does not require power lines, relies on electromagnetic wave propagation, and then converts electromagnetic wave energy into electrical energy, and finally realizes wireless charging. [0003] When the existing wireless charger is...

Problems solved by technology

[0003] When the existing wireless charger is in use, it only has a single wireless charging function. When the receiving coil of the device that needs to be charged or the release coil of the wireless charger is damaged, it is easy to cause the wireless charger to be unusable, thereby reducing the range of use of the wireless charger. and functionality, and the existing wireless chargers are prone to heat during charging, which reduces the safety of wireless chargers
