Description

Technical Field

[0001] This utility model relates to the technical field of wireless charging devices, and in particular to a desktop wireless charger. Background Technology

[0002] Currently, desktop wireless chargers on the market are all powered by wired low-voltage power. As the number of electronic products on the desktop increases, so do the number of wires, making the desktop environment cluttered. The wires are also prone to damage and have a short lifespan. At the same time, wired charging is cumbersome to plug and unplug.

[0003] Currently, there are also products on the market that combine voltage converters and wireless charging receivers. These products can convert external power into a voltage suitable for wireless charging and then transmit it wirelessly to the mobile phone. However, due to the instability of the transmission distance between the transmitting and receiving coils, problems such as low energy conversion efficiency in desktop environments and receiving coils exceeding the receiving distance range are caused by incompatibility between transmitting and receiving power, frequency mismatch, and protocol mismatch. As a result, the compatibility of these products is not high. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a desktop wireless charger. In order to solve the problem of clutter caused by power cords in current desktop charging products, this invention improves the power supply scheme of wired chargers and provides a wireless transmitter charger solution that uses magnetic matching and is powered by a desktop wireless charging module. Ultimately, it achieves the effect of a wireless-to-wireless charger, ensuring the compatibility of the charger.

[0005] To solve the above-mentioned technical problems, the present invention proposes the following technical solution:

[0006] A desktop wireless charger includes a housing, an annular magnet transmitter embedded inside the housing, a coil transmitter embedded in the annular magnet transmitter, a mounting groove inside the cover plate, a functional circuit board mounted in the mounting groove, and an annular magnet receiver embedded at the bottom of the cover plate, a coil receiver embedded in the annular magnet receiver.

[0007] Furthermore, the functional circuit board integrates a wireless charging receiver module, a wireless charging transmitter module, a feedback circuit module, a voltage regulator module, a buck-boost module, and a wireless charging protocol adjustment module. LED lights are electrically connected to the functional circuit board.

[0008] Furthermore, both the annular magnet transmitting end and the annular magnet receiving end are thickened.

[0009] Furthermore, a wireless charging transmitter is movably connected to the bottom of the housing, and the wireless charging transmitter is configured in conjunction with a coil receiver.

[0010] Furthermore, a cover plate is movably mounted on the housing, and the coil transmitter and the annular magnet transmitter are located below the cover plate. The housing also includes a wireless charging receiver, which is configured in conjunction with the coil transmitter.

[0011] As can be seen from the above technical solution, the beneficial effects of this utility model are:

[0012] This invention utilizes the cooperation of wireless receiving and transmitting modules to achieve a hidden desktop wireless power supply, resulting in a simpler product appearance and a more straightforward and concise usage logic.

[0013] This solution integrates a wireless charging receiver module, a voltage conversion and power management module, a wireless charging module, and a product operating status feedback module, achieving a unified solution for wireless-to-wireless conversion.

[0014] The thickened ring-shaped strong magnet at the transmitter end of the wireless charging module, combined with the thickened ring-shaped strong magnet at the receiver end of the product, achieves better wireless power-on matching feedback and provides a more stable power environment that is less prone to disconnection in desktop environments.
