Description

Technical Field

[0001] This utility model relates to an electronic product, and more particularly to a wireless charger. Background Technology

[0002] A prior art wireless charger includes a first charging module and a second charging module. The first charging module contains a circuit board and a first charging coil, and the second charging module contains a second charging coil. This wireless charger also includes a third charging module for charging a smartwatch, which is rotatably connected to the second charging module. The first and second charging modules are electrically connected via flat silicone wires. Because the silicone wires are relatively stiff, the connection between the first and second charging modules is rigid, making it difficult to freely and conveniently adjust their relative angle and position during use. Utility Model Content

[0003] The technical problem to be solved by this utility model is to provide a wireless charger.

[0004] To solve the above technical problems, the present invention provides a wireless charger, comprising a first charging module, a second charging module, and a circuit board. The first charging module is provided with a first charging coil, and the second charging module is provided with a second charging coil. The first charging module and the second charging module are electrically connected by braided wires, and the first charging module is provided with a support portion.

[0005] Preferably, the circuit board is disposed within the first charging module, one end of the braided wire is connected to the first charging module through a first inner fastener and a first outer fastener, and the wall of the first charging module is clamped between the first inner fastener and the first outer fastener; the other end of the braided wire is connected to the second charging module through a second inner fastener and a second outer fastener, and the wall of the second charging module is clamped between the second inner fastener and the second outer fastener.

[0006] Preferably, the first charging module is provided with a limiting wall for limiting the first inner fastener; the second charging module is provided with a limiting wall for limiting the second inner fastener.

[0007] Preferably, the first charging module includes a first bottom shell, a first middle frame, and a first cover. The circuit board is fixed to the first bottom shell, the first charging coil is fixed to the first middle frame, and the support is rotatably connected to the first bottom shell.

[0008] Preferably, one end of the support is provided with a pivot, the first bottom shell is provided with a through hole for the support to pass through, and the pivot is press-fitted into the first bottom shell by a pressure plate.

[0011] Preferably, the first middle frame is further provided with a ring magnet.

[0012] Preferably, the wireless charger further includes a third charging module, which is rotatably connected to the second charging module.

[0013] Preferably, the second charging module is provided with a groove for accommodating the third charging module.

[0014] The first and second charging modules are electrically connected via braided wires. Compared to existing silicone wires, braided wires are more flexible and easier to bend and twist, allowing for more flexible and convenient adjustment of the relative position and angle between the first and second charging modules connected to both ends of the braided wire. This makes the wireless charger more flexible and convenient to use. The first and second charging modules can be placed flat on a table for charging; the first charging module can be tilted with its support to charge a mobile phone, suitable for scenarios where a video is played while the phone is being charged; the second charging module can be placed flat on the table to charge another electronic device; and the third charging module can be opened to charge a watch. Because the braided wire is flexible and easy to twist, the angle of the first and second charging modules can be easily adjusted. The first and second charging modules can be attracted to each other by magnets. Due to the sufficient toughness of the braided wire, it can also be used as a carrying strap for easy portability.

Figure 3 As shown, the first charging module 1 can be tilted to charge a mobile phone under the support of its support part 18, suitable for scenarios where a video is played while the phone is being charged. The second charging module 2 can be placed flat on a table to charge another electronic product, and the third charging module 3 can also be opened to charge a watch. Because the braided cable 5 is very flexible and easy to twist, the angles of the first charging module 1 and the second charging module 2 can be easily adjusted. It can also be used as follows... Figure 5 and Figure 6 As shown, the first charging module 1 and the second charging module 2 are attracted to each other by magnets. Since the braided wire 5 also has sufficient flexibility and toughness, it can also be used as a carrying rope for easy carrying.
