Problems solved by technology

However, chargers using wireless charging technology currently on the market usually only have a single-turn coil, and the number of coil turns cannot be changed. However, the charging power and charging current of electronic products are not the same, and a single-turn charging coil is difficult to meet. Charging requirements of different models / specifications of electrical appliances

Embodiment Construction

[0024] The specific implementation manners of the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. The following examples are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0025] see figure 1 As shown, a coil for the antenna of a wireless charging device includes a microchannel 1 and a liquid metal 2 . The micro-channel 1 is coiled into a coil shape, and the liquid metal 2 is filled in the micro-channel 1 . The liquid metal 2 filled in the micro-channel 1 together with the micro-channel 1 forms a conductive coil for generating an induced magnetic field to realize energy transmission.

[0026] According to actual application conditions, the diameter of the micro-channel 1 is adjusted to balance the resistance of the adjustment coil and the energy of the induced magnetic field generated. The pipe diameter of the micro-channel 1 ranges from ...

Abstract

The invention provides a coil used for a wireless charging device antenna. The coil comprises a micro channel coiled to be coil-shaped and liquid metal fillingthe micro channel. The liquid metal is injected into or pumped out of the micro channel by a micro injection pump connected with the micro channel, but the length of the liquid metal in the micro channel is changed, so that the strength of a generated induced magnetic field is changed, and the coil can output energy with different powers. The coil used for the wireless charging device antenna provided by the invention is simple in structure and high in applicability.

Description

technical field [0001] The present invention relates to the technical field of wireless charging, and more particularly, to a coil used for an antenna of a wireless charging device. Background technique [0002] Wireless charging technology originates from wireless power transmission technology, which is divided into electromagnetic induction type, magnetic field resonance type and radio wave type. When charging with wireless charging technology, the charger and the electric device do not need to be connected by wires, but the energy is directly transmitted by the magnetic field between the two, so that the charger and the electric device do not need to expose conductive contacts, which improves the safety of use . [0003] In the electromagnetic induction wireless charging method, a coil is respectively arranged in the charger and the electric device. The alternating current of a certain frequency is passed into the primary coil installed in the charger, and the primary c...
