[0023] The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, illustrating only the basic structure of the present invention, and therefore only show the components relevant to the present invention.

[0024] like Figure 1-6 As shown, a portable wireless charging device includes a housing 1, a charging head 2, and a connecting mechanism. The charging head 2 is connected to the housing 1 through the connecting mechanism, and a battery pack is provided inside the housing 1.

[0025] The charging head 2 is provided with a wireless charging module and a first magnet. The charging head 2 is provided with a cylindrical protrusion 4, and a second magnet is provided inside the cylindrical protrusion 4.

[0026] The connecting mechanism includes a main body 6, a coil inside the main body 6, a wire 3 wound on the coil, one end of the wire 3 being electrically connected to the battery pack, and the other end of the wire 3 extending out of the housing 1 and being electrically connected to the wireless charging module inside the charging head 2.

[0027] The housing 1 has a cylindrical groove 5 at the position corresponding to the cylindrical protrusion 4. The protrusion 4 is located in the groove 5. A third magnet is provided in the groove 5. The second magnet and the third magnet attract each other.

[0028] The housing 1 is provided with a guide ring 7, which is located on one side of the groove 5, and the inner ring of the guide ring 7 matches the shape of the wire 3.

[0029] The charging head 2 has a guide groove on the side facing the housing 1 that matches the guide ring 7, and the guide ring 7 is located in the guide groove.

[0030] Preferably, the housing 1 is provided with a power switch, a charging interface and a power indicator light.

[0031] Preferably, the battery pack is a lithium battery.

[0032] Preferably, the conductor 3 is a flat wire.

[0033] Here, the first magnet inside the charging head 2 is used to attract the device that needs to be charged, such as a mobile phone, and attach it to the back of the phone.

[0034] The second magnet of the protrusion 4 and the third magnet in the groove 5 attract each other, mainly to achieve stable storage of the charging head 2 on the housing 1.

[0035] Here, the device that needs to be charged can be directly attached to the charging head 2, or the charging head 2 can be pulled up separately. When the charging head 2 is pulled up, the wire 3 is pulled out from the main body 6 and extended. At this time, the shell 1 does not need to move. That is, only the charging head 2 is attached to the device that needs to be charged, which is very convenient and not cumbersome to move. The current is transmitted through the wire 3, and the device is charged through the wireless charging module of the charging head 2.

[0036] When not in use, the protrusion 4 of the charging head 2 can be magnetically attached to the groove 5, and the wire 3 is stored in the coil inside the main body 6, which reduces the storage volume and improves lightness and flexibility.

[0037] A guide ring 7 is provided at one end of the housing 1 with a groove 5. It mainly serves to guide the wire 3 and prevent the wire from getting stuck. In fact, in order to make the overall design consistent, the shape of the charging head 2 and the housing 1 are usually designed to be the same, which makes it look more aesthetically pleasing. Since the protrusion 4 and the groove 5 are actually cylindrical, the guide ring 7 also serves to prevent fooling when the charging head 2 is connected to the housing 1. This eliminates the need for an additional adjustment step when the charging head 2 and the housing 1 are connected, ensuring that the head and body are consistent.

[0038] Preferably, the cylindrical protrusion 4 has an arc-shaped chamfer at the edge near the end of the housing 1.

[0039] Compared with existing technologies, this portable wireless charging device adopts a split structure design, separating the charging head assembly and the power bank assembly, and setting up a power cord 3 with storage and adjustment functions, realizing convenient separation of the head and body, improving the convenience of wireless charging and enhancing the user experience.

[0040] Based on the above-described preferred embodiments of this utility model, and through the foregoing description, those skilled in the art can make various changes and modifications without departing from the technical concept of this utility model. The technical scope of this utility model is not limited to the contents of the specification, but must be determined according to the scope of the claims.
