Embodiment 1

[0025] see figure 1 and figure 2 , figure 1 It is a schematic cross-sectional view of a wireless charger disclosed in the embodiment of this application. figure 2 It is a schematic diagram of planar structure of a wireless charger disclosed in the embodiment of this application.

[0026] As shown in the figure, the wireless charger includes an upper cover 11 , a charging coil 12 , a ferrite 13 , a printed circuit board assembly 14 and a lower cover 15 . Wherein, the charging coil 12 is arranged above the ferrite 13 , and the printed circuit board assembly 14 is a hollow structure, and the charging coil 12 and the ferrite 13 are placed in the through holes in the middle. Finally, the upper cover 11 and the lower cover 15 are added together to form a wireless charger.

[0027] Since the printed circuit board assembly 14 is designed as a hollow structure, the charging coil 12 and the ferrite 13 can be placed inside the printed circuit board assembly 14, so that the charging...

Embodiment 2

[0029] Continue to see attached figure 1 And attached figure 2 , the ferrite 13 in the figure is to prevent the magnetic field generated by the charging coil 12 from affecting the printed circuit board assembly 14, but if the power is strong enough, a single ferrite 13 cannot completely shield the electromagnetic field. Therefore, we A metal bracket 16 is further added between the ferrite 13 and the printed circuit board assembly 14, and the metal bracket 16 further isolates the printed circuit board assembly 14 and the ferrite 13, further ensuring that the electromagnetic field of the charging coil 14 will not Affects the printed circuit board assembly 14.

[0030] Of course, the specific structure of the metal bracket 14 can be varied, as long as the above effects can be achieved. Here we give an example of a more preferred solution:

[0031] We set the metal bracket 16 as figure 2 In the shown structure, the metal bracket 16 presents a groove shape as a whole, a part ...

Abstract

The invention discloses a wireless charger which is composed of an upper cover, a charging coil, a ferrite, a printed circuit board component and a lower cover. The charging coil is arranged on the ferrite, and the printed circuit board component is of a hollow structure so that the charging coil and the ferrite can be arranged in the hollow structure of the printed circuit board. The thickness of the final charger formed through combination is equal to the sum of the thickness of the upper cover, the thickness of the lower cover and the thickness of the printed circuit board component, the thicknesses of the traditional charging oil and the ferrite are omitted, the overall thickness of the wireless charger is greatly shortened, and the wireless charger is more convenient to carry.

Description

technical field [0001] The present application relates to the technical field of wireless charging devices, and more specifically, to a wireless charger. Background technique [0002] A wireless charger refers to a device that uses the principle of electromagnetic wave induction for charging, which is similar to a transformer. There is a coil at the sending and receiving ends. The coil at the sending end is connected to a wired power supply to generate an electromagnetic signal, and the receiving end induces the electromagnetic signal at the sending end to generate current to charge the battery. [0003] However, the current wireless charger is designed with a multi-layer laminated structure. Its main structure is: lower cover, printed circuit board assembly, ferrite and charging coil, and upper cover. These components are stacked together from bottom to top, assembled into a finished product. The sum of the thicknesses of each layer of material is the total thickness of t...
