Description

Technical Field

[0002] Traditional wireless charging devices generally use a fixed power cord to connect to the power source, which makes them inconvenient to carry. For this reason, people have invented charging devices that combine retractable data cables with wireless charging to improve the ease of use of the product. However, existing devices that combine retractable cables with wireless charging generally use a wire that passes through the central axis of the shell and then connects to the circuit board. The disadvantage of this structure is that the wire must pass through the central axis as a whole, which is more troublesome to operate, and the welding point with the circuit board may be torn off if the wire is not threaded carefully. In addition, current data cable devices of this type are connected to chargers or computers and other devices with USB interfaces via data cables, but some occasions do not have such devices with USB interfaces. In this case, it is impossible to power the wireless charger and charge the mobile phone through such charging devices. Utility Model Content
