Description

Technical Field

[0001] The utility model relates to a receiver, in particular to a wireless charging receiver. Background Art

[0002] Wireless charging technology is a technology that transfers electrical energy to a receiver without physical contact through electromagnetic induction, electromagnetic radiation, magnetic resonance, etc., thereby charging electronic devices. Wireless charging technology can avoid the problems of cable damage and inconvenience in plugging and unplugging in traditional wired charging methods, and improve the convenience and safety of charging. At present, wireless charging technology has been widely used in electronic devices such as mobile phones, smart watches, electric toothbrushes, and smart homes.

[0003] In the prior art, wireless charging technology has been widely used, but most of the existing wireless charging devices are designed for devices with wireless charging functions and cannot be used for devices without wireless charging functions. Utility Model Content

[0004] The technical problem to be solved by the utility model is to provide a wireless charging receiver to solve the problems existing in the background technology.

[0005] The wireless charging receiver of the utility model is realized by the following technical scheme, comprising: a wireless charging receiver body, wherein a receiving coil is integrated inside the wireless receiving charger body, and a magnetic attraction ring is arranged outside the receiving coil.

[0006] As a preferred technical solution, the wireless charging receiver body includes a circuit board and a copper coil;

[0007] The receiving coil is integrated on the circuit board, and an installation cavity is provided on the outside of the receiving coil of the circuit board, and the magnetic ring is embedded in the installation cavity; the copper coil is arranged above the receiving coil, and the copper coil is connected to the circuit board, and the copper coil is used as a power inductor to make the product thinner.

[0008] As a preferred technical solution, the copper coil is covered with a first ferrite sheet and a second ferrite sheet above and below, respectively.

[0009] As a preferred technical solution, the stickers above and below the circuit board are respectively attached to the top and bottom of the circuit board to wrap the circuit board.

[0010] As a preferred technical solution, a flexible cable connector is connected to the circuit board.

[0011] The beneficial effects of the utility model are as follows: the utility model can charge electronic devices through the wireless charging base, which makes up for the charging function that the electronic devices themselves do not have. Electronic devices without wireless charging function can also be wirelessly charged using the wireless charging base through this product, and electronic devices that support fast charging can be quickly charged. By using the copper coil as the power inductor, the product can be made thinner. BRIEF DESCRIPTION OF THE DRAWINGS
