Description

Technical Field

[0001] The utility model relates to the field of wireless charging, in particular to a double-sided wireless charger. Background Art

[0002] With the development of science and technology, electronic products are widely used. While using electronic products brings convenience and benefits, the charging process of electronic products is a more troublesome link for users. This is because the charging interfaces of different electronic products are often different. Against this background, wireless charging technology came into being.

[0003] Wireless charging technology is mainly divided into three types: electromagnetic induction, magnetic field resonance and radio wave. Among them, electromagnetic induction is the most common one at present. Its operating frequency is usually between several hundred and several thousand hertz, and its transmission power is generally between tens and hundreds of watts. The transmission power of magnetic field resonance is higher, which can reach the kilowatt level, and it can realize one-to-many wireless charging. Radio wave mainly transmits through microwaves, and its transmission distance is long, but the efficiency is low.

[0004] When using wireless charging for charging, some existing wireless charging devices often have only one charging surface, and can be used to charge a small number of electronic products, usually only one of which can be used, such as a mobile phone or a watch. The function of charging only one electronic product obviously cannot meet the user's charging needs for different electronic products, and therefore has a poor scope of application.

[0005] Therefore, in order to solve the above-mentioned technical problems, we propose a double-sided wireless charger. Utility Model Content

[0006] In view of this, the present invention aims to provide a double-sided wireless charger to solve the above problems.

[0007] To achieve the above-mentioned purpose, the utility model adopts the following technical solution: comprising a packaging shell, a packaging cover 1 for sealing one end of the packaging shell, and a packaging cover 2 for sealing the other end of the packaging shell, a ring magnet is clamped and installed in the packaging shell, and a double-sided wireless charging component is arranged in the packaging shell;

[0008] The wireless charging component includes a charging coil 1, a PCB control circuit board and a charging coil 2 which are stacked in sequence.

[0009] As a preferred solution, the charging coil 1 and the charging coil 2 are both electrically connected to the PCB control circuit board.

[0010] As a preferred solution, one end of the PCB control circuit board is connected to a charging port, and the charging port is fixed to the PCB control circuit board by welding.

[0011] As a preferred solution, the charging port can adopt any one of a standard USB interface, a Mini USB interface, a Micro USB interface, and a Type-C interface.

[0012] As a preferred solution, the charging port can adopt any one of a standard USB interface, a Mini USB interface, a Micro USB interface, and a Type-C interface.

[0013] As a preferred solution, the packaging shell is formed by integral die-casting.

[0014] Compared with the prior art, the utility model has obvious advantages and beneficial effects. Specifically, it can be seen from the above technical solution that the main advantages are:

[0015] The device can charge different types of electronic products by using a double-sided wireless charging assembly consisting of a charging coil 1, a PCB control circuit board and a charging coil 2 in conjunction with a charging port, thereby increasing the scope of application of the device.

[0016] In addition, thanks to the improvement of the efficiency of the packaging shell through one-piece molding, one-piece die-casting reduces the assembly steps required for the combination of parts, thereby improving production efficiency. Since the assembly steps are reduced, the company can save a lot of manpower and material costs. The one-piece die-casting process can ensure the overall structural strength and precision of the product, thereby improving product quality. One-piece die-casting technology can achieve lightweight design of the product, thereby reducing the weight of the product and improving the portability and energy efficiency of the product.
