The wire winding assembly 30 includes a wire winding disc 31, an elastic member 32, and a wire 33. The elastic member 32 is cooperatively connected with the wire winding disc 31. The wire 33 is wound around the wire winding disc 31 and one end thereof is connected to the wire winding disc 31 and electrically connected to the circuit board 20, and the other end can extend outwards from the main body 10. Thus, the redundant wire 33 extending outwards is retracted into the main body 10 by the elastic member 32, avoiding the wire 33 extending out too long and being entangled with external objects. At the same time, it can also protect the wire 33 and prevent the wire 33 from being damaged. One end of the wire 33 is electrically connected to the circuit board 20, and the other end of the wire 33 can extend outwards from the main body 10. The circuit board 20 can be connected to an external power supply through the other end of the wire 33, so as to supply power to the wireless charging module 40 for wirelessly charging an electronic device.

By electrically connecting the first connector 34 to the external power supply, not only can the circuit board 20 and the two wireless charging modules 40 be powered on, but also the second connector 35 can be used to realize the wired charging process for the external electronic device, with stronger functionality and the ability to simultaneously meet the charging processes of three different electronic devices in different ways. The first connector 34 is a power plug, and the second connector 35 is a Type-C connector. Similarly, the second connector 35 can also be a Micro USB connector or a Lighting connector according to actual situations, not limited thereto. The first connector 34 can also be a Type-C connector or a Micro USB connector suitable for connecting to a charger, etc. A groove 102 for cooperating with the first connector 34 and the second connector 35 respectively is recessed on the side wall of the main body 10, so that when not in use, the first connector 34 and the second connector 35 can be received in the two grooves 102, and the user experience will be better. In other embodiments, it can also be to only provide one groove 102 for simultaneously receiving the first connector 34 and the second connector 35. The wire winding disc 31 is sleeved on the connecting rod 111 and can rotate back and forth around the connecting rod 111.

One end of the wire 33 in each wire winding assembly 30 is connected to the corresponding circuit board 20, and the other end extends out of the corresponding first body 14 and second body 15. Each wireless charging module 40 is correspondingly disposed above the wire winding assembly 30 and is electrically connected to the corresponding circuit board 20, so that a single wire 33 controls the on-off of the circuit of the corresponding wireless charging module 40. When only wireless charging of a single electronic product is required, only the outer end of a single wire 33 needs to be plugged into an external power source, and the electronic product is placed at the corresponding position of the corresponding wireless charging module 40, which further improves the user experience and can also avoid waste of electricity; of course, the circuit boards 20 in the first body 14 and the second body 15 can also be arranged to be electrically connected to each other, so that when only one end of one of the wires 33 is connected to an external power source, it can also supply power to the wireless charging modules 40 in both the first body 14 and the second body 15 at the same time, and at the same time, when one end of the other wire 33 is connected to an external electronic device, it can realize wired charging of the external electronic device through the wire 33.

[0046] A first hinge portion 141 is provided on the first body 14, a second hinge portion 151 that cooperates with the first hinge portion 141 is provided on the second body 15, and a hinge rod 16 sequentially passes through the first hinge portion 141 and the second hinge portion 151 to hinge the first body 14 and the second body 15.

[0047] The design focus of the present utility model lies in that: its wire winding assembly includes a wire winding disc, an elastic member and a wire. The elastic member is cooperatively connected with the wire winding disc. The wire is wound around the wire winding disc and one end is electrically connected to the circuit board, and the other end can extend out of the body; so that the wire of the charger can be retracted into the body under the drive of the elastic member, which not only prevents the extended part of the wire from being entangled with external objects and affecting the user experience, but also plays a protective role for the wire; and in cooperation with the wireless charging module, at least two are provided, so that the wireless charging processes of at least two different electronic devices can be completed simultaneously, without the need to carry different chargers, reducing the carrying pressure of the user's items during travel, and at the same time, with the setting of at least two wireless charging modules, the charging efficiency is also higher.

[0048] The above is only a preferred embodiment of the present utility model, and does not impose any limitation on the technical scope of the present utility model. Therefore, any minor modification, equivalent change and modification made to the above embodiment based on the technical essence of the present utility model still fall within the scope of the technical solution of the present utility model.
