Description

Technical Field

[0001] This utility model relates to the technical field of wireless charging mouse pads, specifically to a full-disk magnetic wireless charging device for mouse pads. Background Technology

[0002] The wireless charging mouse combines a wireless phone charger and a mouse pad into a single 2-in-1 product, offering significant advantages. It primarily addresses several core pain points in modern desktop environments: reducing the need for separate devices and consolidating cables, resulting in a cleaner and more organized desktop; merging the functions of two essential accessories into a single physical space, maximizing desktop space utilization; and keeping your phone fully charged during work, gaming, or study breaks, ready to use at any time.

[0003] Chinese patent application CN202021401757.9, entitled "A Wireless Charging Mouse Pad," discloses a wireless charging mouse pad. It features a PCBA board within a rubber pad, a wireless charging coil on the PCBA board, a charger, and a charging port. By inserting the charger into the charging port, the PCBA board and wireless charging coil are powered. Users can then simply place a wirelessly charging-enabled mobile phone on the top right side of the mouse pad to charge it, avoiding the problem of forgetting to bring a phone charger and being unable to charge their phone. This is highly practical.

[0004] However, the above patent still has the following shortcomings. Many users choose large mouse pads to place their keyboards and mice. For example, the general size is 30*80cm. Large mouse pads have a large area and can place both the keyboard and mouse at the same time, increasing the operating area of ​​the mouse and making it more convenient to use. The above patent only has one wireless charging area. The mobile phone needs to be placed in a specific area to charge. Since the right side of the mouse pad needs to reserve enough space for the mouse, the placement of the keyboard will be affected by each person's usage habits and the size of the keyboard, which may cause it to overlap with the wireless charging area, resulting in charging inconvenience. Therefore, it is necessary to design a full-disk magnetic wireless charging device for mouse pads. Utility Model Content

[0005] In view of the above-mentioned technical problems, the purpose of this utility model is to overcome the problem that charging is inconvenient due to different individual usage situations in the prior art.

[0006] To achieve the above objectives, this utility model provides a full-disk magnetic wireless charging device for mouse pads, comprising: a lower mouse pad with edges protruding upwards to form a mounting groove; a heat sink plate assembled in the mounting groove; a mounting plate located in the mounting groove and above the heat sink plate; wireless charging units arranged in a matrix and assembled on the mounting plate; a power board for connecting several wireless charging units; and an upper mouse pad laid on top of the magnetic power board and covering the opening of the mounting groove. Each of the wireless charging units includes an NFC module.

[0007] Preferably, the heat sink is in the form of a grid.

[0008] Preferably, the heat sink is hollow.

[0009] Preferably, the mounting plate is provided with windows that correspond one-to-one with a plurality of wireless charging units.

[0010] Preferably, the bottom of the lower mouse pad is equipped with an anti-slip pad.
