The heat dissipation housing 30 is connected to the first housing 10 or the second housing 20, and a portion of the heat dissipation housing 30 is disposed on the outermost side of the wireless charging power bank 90. ​​The coil 50 is electrically connected to the battery 40 for wirelessly charging external devices. The coil 50 abuts against the heat dissipation housing 30, and the heat dissipation housing 30 is used to conduct the heat generated by the coil 50 and the battery 40 to the outside.

This prevents the wireless charging power bank from reducing power, burning the user, or spontaneously combusting due to overheating. The heat dissipation shell provides the wireless charging power bank with good heat dissipation performance, providing users with a better user experience and improving the safety of the wireless charging power bank.

[0042] It is understood that the battery is located inside the wireless charging power bank and abuts against the first and second housings. The heat dissipation housing is connected to the first or second housing, and part of the heat dissipation housing is connected to the coil. When the wireless charging power bank is working, the heat generated by the coil and the battery will be conducted to the heat dissipation housing, and the heat dissipation housing will conduct the heat to the external environment.

[0054] It is understandable that the second shaft hole of the coil is fitted onto the first convex shaft, and the first shaft hole of the heat sink housing is fitted onto the first convex shaft, which can fix the coil and the heat sink housing. The design is simple and practical.

[0055] Furthermore, the wireless charging power bank 90 also includes a cover plate 70 that matches the size of the second annular groove 32. A second convex shaft 71 is provided in the center of the inner side of the cover plate 70. A protruding first locking block 72 is provided on one side of the second convex shaft 71. The second convex shaft 71 passes through the first shaft hole 31a and the second shaft hole 51 and is inserted into the hollow first convex shaft 11a. The first locking block 72 is engaged with the inner wall of the first housing 10 so that the cover plate 70 covers the coil 50 and is installed in the second annular groove 32.

[0056] It is understood that the second convex shaft in the center of the cover plate can be inserted into the hollow first convex shaft, and the first locking block provided on the second convex shaft can be engaged with the inner side wall of the first housing so that the cover plate is connected to the first housing; the second convex shaft is elastic, which makes it convenient for users to install and remove the cover plate.

[0060] It is understandable that after the extended end of the magnet passes through the first through hole and the second through hole, the protrusion on the extended end can engage in the slot in the first housing so that the magnet is fixed in the second annular groove. The design is simple and practical, and facilitates quick assembly and disassembly.

[0061] Furthermore, the wireless charging power bank 90 also includes a control circuit board 80, which is disposed within the housing space and electrically connected to the battery 40.

[0062] It is understandable that the control circuit board can control the power on and off of the wireless charging power bank, and can also convert current into alternating current and conduct it to the coil, so that the coil generates a magnetic field.

[0065] Furthermore, an indicator light 81 is provided on the control circuit board 80; a slot 24 is provided on the second housing 20 at the position corresponding to the indicator light 81.

[0066] It's understandable that there are several indicator lights arranged in sequence. The more battery power remaining, the more indicator lights will be lit, and the less battery power remaining, the fewer indicator lights will be lit.

[0067] In some embodiments, there may be one indicator light, and the color of the indicator light changes according to the amount of battery power.

[0068] Users can see the indicator light through the slot, thus knowing how much battery power is left, improving the user experience.

[0069] Furthermore, a power interface 82 is also provided on the control circuit board 80.

[0074] It is understood that there are several second connectors and several first slots. The positions of the several second connectors correspond one-to-one with the positions of the several first slots. After the second connector is inserted into the first slot, the third locking block on the second connector engages in the third connecting hole in the first slot, so that the first housing is locked onto the second housing.

[0077] Furthermore, several heat dissipation grooves 36 are provided on the surface of the heat dissipation housing 30.

[0078] It is understandable that heat dissipation grooves can increase the heat dissipation area of ​​the heat dissipation shell, further improving the heat dissipation performance of the heat dissipation shell. At the same time, when external devices are placed on the wireless charging power bank for charging, the heat dissipation grooves can reduce the contact area between the heat dissipation shell and the external devices, resulting in less heat accumulation and improved heat dissipation performance.

[0079] Furthermore, the wireless charging power bank 90 also includes a heat insulation plate 91, which is disposed on both sides of the battery 40. The heat insulation plate 91 can be made of aerogel.

[0080] It is understandable that there are two heat insulation plates. When the wireless charging power bank is working, the battery will generate heat. The heat insulation plates are attached to both sides of the battery and cover the main surface of the battery. This can effectively block the heat generated by the battery from being transferred to the outer casing, providing users with a better user experience. At the same time, the heat insulation plates can also act as a buffer to protect the battery.

[0081] Furthermore, the surface of the cover plate 70 is provided with several strip-shaped protrusions 75.

[0082] It is understandable that the several strip-shaped protrusions on the surface of the cover plate can increase the surface area of ​​the cover plate, thereby increasing the heat dissipation area and further enhancing the heat dissipation performance.
