Description
Technical Field
[0001] This utility model relates to the field of wireless charging technology, specifically to a multifunctional wireless charging device. Background Technology
[0002] Wireless charging devices have been widely accepted and recognized due to their convenience and speed. The principle of wireless charging is electromagnetic induction. Energy is transferred between the wireless charging device and the electronic device to be charged through a magnetic field. There is no need for a wired connection between the wireless charging device and the electronic device to be charged. It has a high degree of intelligence and has been widely used in various fields.
[0003] Wireless power banks can power electronic devices wirelessly. They also have a power storage function, serving as a backup power source when no external power source is available during travel. However, few wireless charging devices on the market integrate the charging device with a wireless power bank. Furthermore, the power supply for wireless charging devices typically includes a power adapter, which converts AC power into DC power required by the device. Common power supply devices have a plug extending from the adapter and plugged directly into a wall socket, with only a single cable connecting the adapter to the wireless charging device. However, external cables are difficult to manage and tend to become tangled, and the adapter's large size makes it inconvenient to store, especially when frequently moving the device during travel. Users may also need to carry multiple wireless charging devices and corresponding power supplies to charge multiple electronic devices simultaneously, further exacerbating the portability issue. Therefore, a multi-functional wireless charging device is urgently needed to solve these problems. Utility Model Content

The second housing 3 supports the first housing 2 and the third housing 4. The second housing 3 is provided with a first receiving groove 31 and a second receiving groove 32. The third housing 4 is rotatably received in the first receiving groove 31 via a second pivot 7. The power adapter 5 is received in the second receiving groove 32. The power adapter 5 is connected to the second housing 3 via a retractable flexible conductive strip 8.
[0025] Specifically, the multifunctional wireless charging device further includes a first wireless charging module, a second wireless charging module 11, and a third wireless charging module. The first wireless charging module is located inside the wireless power bank 1 and is used to charge the mobile phone 9.

[0029] In some specific embodiments, the first housing 2 and the second housing 3 can be magnetically attracted together, and the power adapter 5 can be attracted by a magnet or fixed to the bottom of the second housing 3 by a slot structure, making the structure compact and easy to carry. More specifically, magnetic elements or slot elements can be provided on both sides of the inner groove or the bottom of the groove of the second receiving groove 32. When the power adapter 5 is received in the second receiving groove 32, it cooperates with the magnetic elements or slot elements to fix the power adapter 5 in the second receiving groove 32 by using the magnetic or snap-fit structure.
[0030] More specifically, the first rotating shaft 6 and the second rotating shaft 7 are respectively provided with damping structures so that the first housing 2 and the third housing 3 can be positioned at any preset position when they are flipped.
[0031] Specifically, the wireless power bank 1 is detachably connected to the first housing 2. After the wireless power bank 1 is removed, the charging male interface 10 can be directly used to supply power to the device to be charged.
[0032] In some specific embodiments, when using this multifunctional wireless charging device, first, flip the power adapter 5 out of the second receiving slot 32 and insert it into an external power source. Then, place the second housing 3 on a table, open the first housing 2 that is closed on top of the second housing 3, and then plug the female charging port of the wireless power bank 1 into the male charging port 10 on the first housing 2. Finally, flip the third housing 4 out of the first receiving slot 31. Place the earphone on the second housing 3 to charge, place the mobile phone 9 on the wireless power bank 1 to charge, and place the watch on the third housing 4 to charge. Alternatively, the wireless power bank 1 can be removed from the male charging port 10. The wireless power bank 1 can be used to charge one mobile phone 9 alone, and the male charging port 10 can be directly connected to another mobile phone 9 for charging. Here, the male port is preferably a Type-C type interface, but other mobile phone interface types can also be used.

The first housing 2 is provided with the magnet, and the wireless power bank 1 is provided with the magnetic attractor. The wireless power bank 1 is magnetically connected to the first housing 2, and the wireless power bank 1 is magnetically attracted to the device to be charged.
[0036] In summary, this multi-functional wireless charging device integrates the wireless power bank 1 into the charging male interface 10 on the first housing 2, with the wireless power bank 1 and the first housing 2 magnetically attracted and fixed together. This makes the wireless charging device and the wireless power bank 1 a single unit, easy to carry, and solves the problem of needing a backup power source when no external power source is available during travel. Moreover, the wireless power bank 1 is detachable and can still be charged after removal. In this case, the charging male interface 10 can also be plugged into the receiving device to directly power the device being charged, effectively increasing the number of charging positions and expanding the charging function of the wireless charging device. In addition, this multi-functional wireless charging device has a compact structure by using a second receiving slot 32 on the second housing 3, in which the power adapter 5 is housed, making it convenient to carry and move the wireless charging device. Furthermore, the power adapter 5 is connected to the second housing 3 via a retractable flexible conductive strip 8. After use, the retractable flexible conductive strip 8 retracts and does not protrude, solving the problem of messy and difficult-to-manage cables, further facilitating the carrying and moving of the wireless charging device.
