[0048] The charging module 200 includes an alternating current input module and a direct current output module integrated on a circuit board and electrically connected to each other.

[0049] The alternating current input module is used to connect an external power supply, the direct current output module is electrically connected to the wireless charging module 300 and the retractable cord module 400, and the retractable cord 410 of the retractable cord module 400 is arranged through the through hole.

[0050] It should be noted that the wireless charging module 300 can include a wireless charging drive assembly for converting the direct current output by the direct current output module into alternating current to drive the energized coil to generate an alternating magnetic field, thereby achieving wireless charging of the external electrical appliance.

[0051] In the above embodiments of the present application, the AC input module of the charger is connected to an external power source, and the wireless charging module 300 and the retractable wire module 400 are powered through the direct current output module. In use, the user can pull the connector 411 of the retractable wire 410 of the retractable wire module 400 out of the shell 100 to power the first electronic device; at the same time, the user places the second electronic device on the side of the shell 100 close to the wireless charging module 300, and powers the second electronic device through the wireless charging module 300, thereby reducing the user's dependence on external charging cables and improving portability and convenience.

[0052] Among them, the first electronic device is a device that does not support wireless charging; the number of connectors 411 of the retractable wire 410 of the retractable wire module 400 is at least one to power the corresponding first electronic device; at the same time, the connector 411 of the retractable wire 410 includes at least one of a USB connector, a Micro-USB connector, a Type-C connector, and a Lightning connector; the second electronic device is a device that supports wireless charging.

[0053] As shown in Figure 2 and Figure 3 In some embodiments, the wireless charging module 300 is arranged at the top of the shell 100, the charging module 200 is arranged at the bottom of the shell 100, and the retractable wire module 400 is arranged between the wireless charging module 300 and the charging module 200.

[0054] The charging module 200 generates a certain amount of heat during operation. If the wireless charging module 300 is directly adjacent to the charging module 200, the heat will be transferred to the wireless charging module 300, which will cause the wireless charging module 300 to overheat and reduce the charging power.

[0055] In the present embodiment, the retractable wire module 400 separates the wireless charging module 300 from the charging module 200, which can play a certain heat insulation role, preventing the heat of the charging module 200 from being directly transferred to the wireless charging module 300, thereby reducing the temperature on the side of the wireless charging module 300 and ensuring the stability of the charging power of the wireless charging module 300.

[0056] As shown in Figure 3 In some embodiments, the shell 100 includes a top shell 110, a middle frame 120, and a bottom shell 130.

[0057] The wireless charging module 300 is arranged on the top shell 110, and the telescopic wire module 400 is clamped between the outer wall of the top shell 110 and the middle frame 120; the charging module 200 is arranged in the bottom shell 130 and clamped between the bottom shell 130 and the middle frame 120; and the top shell 110 is fixedly connected with the bottom shell 130 through the middle frame 120.

[0058] In the embodiment, the middle frame 120 is arranged between the charging module 200 and the wireless charging module 300, which is used to fix the top shell 110, the charging module 200 and the bottom shell 130, and also plays a role in heat insulation, further reducing the heat transfer of the charging module 200 to the wireless charging module 300.

[0059] In actual execution, the wireless charging module 300 is arranged in the inner cavity formed by the top shell 110, which can further reduce the heat transfer of the charging module 200 to the wireless charging module 300,

[0060] Avoiding the wireless charging module 300 from being overheated and leading to a decrease in charging efficiency.

[0061] In the specific assembly, a plurality of first connecting columns are protruded from the side of the middle frame 120 facing the top shell 110, and a plurality of top connecting holes corresponding to the first connecting columns are recessed in the bottom of the outer wall of the top shell 110; a plurality of second connecting columns are protruded from the side of the middle frame 120 facing the charging module 200, a bottom connecting hole is recessed in the bottom of the inner wall of the bottom shell 130, and a plurality of avoiding holes corresponding to the second connecting columns and the bottom connecting holes are formed in the circuit board of the charging module 200.

[0062] As shown in FIG. 1, Figure 4 In some embodiments, a heat insulation positioning part 111 is protruded from the side of the top shell 110 facing the telescopic wire module 400, the heat insulation positioning part 111 abuts against the telescopic wire module 400, and a heat insulation gap is formed between the top shell 110 and the telescopic wire module 400.

[0063] In the embodiment, the heat insulation positioning part 111 of the top shell 110 abuts against the telescopic wire module 400, which can position the telescopic wire module 400, so that the first connecting columns of the middle frame 120 correspond to the top connecting holes of the top shell 110, thereby facilitating the installation and fixation of the middle frame 120 and the top shell 110; on the other hand, the heat insulation gap can avoid the heat generated by the charging module 200 from being conducted to the top shell 110 in a contact manner, leading to the temperature rise of the wireless charging module 300.

[0064] As shown in FIG. 1, Figure 5 and Figure 6 In some embodiments, the wireless charging module 300 includes a first energized coil 311 and a second energized coil 312.

[0065] The first energized coil 311 and the second energized coil 312 are arranged in the top shell 110 of the shell 100, the first energized coil 311 is sleeved outside the second energized coil 312, and the first energized coil 311 and the second energized coil 312 are electrically connected with the direct current output module.

[0066] In the embodiment, the wireless charging module 300 further comprises a wireless charging driving assembly for converting the direct current output by the direct current output module into alternating current to drive the first energized coil 311 and the second energized coil 312 to generate alternating magnetic field respectively, wherein the first energized coil 311 is used for wireless charging of large-volume electric appliances such as mobile phones, and the second energized coil 312 is used for wireless charging of small-volume electric appliances such as watches.

[0067] As shown in Figure 6 , for example, the shell 100 is provided with a first magnetic member 321 and a second magnetic member 322, the first magnetic member 321 is annularly arranged around the first energized coil 311, and the second magnetic member 322 is arranged at the middle part of the second energized coil 312.

[0068] The first magnetic member 321 and the first energized coil 311 are provided with a first magnetic isolation member, and the second magnetic member 322 and the second energized coil 312 are provided with a second magnetic isolation member, the first magnetic isolation member and the second magnetic isolation member can concentrate the magnetic field generated by the first energized coil 311 and the second energized coil 312 respectively, reduce the loss and improve the wireless charging efficiency of the target electric appliance.

[0069] At the same time, the first magnetic member 321 and the second magnetic member 322 can adsorb the target electric appliance on the top surface of the shell 100, while ensuring that the target electric appliance maintains the correct charging position during the charging process.

[0070] For example, the first magnetic member 321 comprises a first end and a second end, and the first magnetic member 321 is provided with a notch part 331, the notch part 331 separates the first end of the first magnetic member 321 from the second end of the first magnetic member 321.

[0071] It should be noted that if the first magnetic member 321 is a closed structure, the alternating magnetic field will induce eddy current in the first magnetic member 321, and the eddy current will heat the first magnetic member 321. In the example, the notch part 331 breaks the continuous conductive path on the first magnetic member 321, thereby destroying the condition for forming eddy current to avoid heating of the first magnetic member 321.

[0072] As shown in Figure 6As shown, in actual implementation, the shell 100 is provided with a wire passing opening 332 for the wire harness to pass through, and the wire passing opening 332 is arranged at the notch portion 331, so as to utilize the space at the notch portion 331 to provide a wire passing path and optimize the layout of the wire harness. The wire harness can electrically connect the first energized coil 311 and the second energized coil 312 with the wireless charging drive assembly of the wireless charging module 300.

[0074] In this embodiment, the joint 411 of the stretchable wire 410 of the stretchable wire module 400 is hidden and protected by the receiving groove 133, so as to avoid damage to the joint 411 of the stretchable wire 410 in use environments such as pulling and extrusion; meanwhile, the joint 411 of the stretchable wire 410 also occupies less space outside the shell 100.

[0075] In actual implementation, the receiving groove 133 is configured to pluggably receive the joint 411 of the stretchable wire 410. Specifically, the joint 411 includes a main body portion and an electrical connection portion connected with each other, and the main body portion is perpendicular to the electrical connection portion. When the joint 411 is pluggably received in the receiving groove 133, the electrical connection portion of the joint 411 is also inserted in the receiving groove 133, so as to protect the electrical connection portion of the joint 411.

[0076] As shown in Figure 2 In actual implementation, the end portion of the receiving groove 133 and the joint 411 of the stretchable wire 410 of the stretchable wire module 400 form a hand gripping position 134. In this way, the user can conveniently take out the joint 411 of the stretchable wire 410 of the stretchable wire module 400 from the receiving groove 133 from the hand gripping position 134.
