[0063] Please refer to Figure 3 , in this embodiment, the charging terminal 113 is provided on the main body 11 and is electrically connected to the first PCB board 112.

[0064] Specifically, the first magnetic member 111 is disposed close to the first PCB board 112, and the second magnetic member 101 is disposed close to the second PCB board 102, so that the wireless charging device 10 is correctly aligned with the slot 121 and attracted together while also guiding the insertion fit of the charging terminal 113 and the charging interface 104.

[0065] Furthermore, the width of the slot 121 (such as Figure 4 L in

[0066] increases gradually along the depth of the slot 121. Figure 4 Understandably, during the process of inserting the wireless charging device 10 into the slot 121, it fits against the inner wall of the slot 121. The gradually increasing width of the slot 121 (such as Figure 4 L in

[0067] ensures that the wireless charging device 10 has sufficient support area when placed in the slot 121, and the width of the wireless charging device 10 also changes adaptively with the width of the slot 121 (such as

[0079] Specifically, in this embodiment, the partition 116 is arranged in parallel with the charger circuit board 117, and the charger circuit board 117 is arranged on the side away from the wireless charging device 10, which can achieve physical isolation between the wireless charging device 10 and the charger circuit board 117. The partition 116 has the effect of shielding magnetic field interaction, avoiding the influence of the wireless charging device 10 charging the wearable device on the process of the charger 1 charging the smart phone.

[0080] Furthermore, the partition 116 can be made of a material with good magnetism such as iron, nickel or alloy.

[0092] Furthermore, as Figure 8 shown, a charging circuit 6 is provided on a charger 5 provided in the fifth embodiment of the present utility model. The charging circuit is as Figure 9 shown, Figure 9 which is the circuit diagram of the charging circuit 6.

[0093] Specifically, the charger 5 provided in this embodiment adopts the same type of output interface 115 as the charger 1 provided in the first embodiment of the present utility model, that is, the charger 5 has two output interfaces 115 of one type of USB-A type and one type of USB Type-C type; and has the same charging terminal 113 and charging interface 104 as the charger 1 provided in the first embodiment. The charging terminal 113 is arranged on the main body 11, and the charging interface 104 is arranged on the wireless charging device 10.

[0094] Specifically, the first PCB board 112 and the charger circuit board 117 arranged in the main body 11, the second PCB board 102 and the wireless charging circuit board 105 arranged in the wireless charging device 10, and the wireless charging module 106 provide the feasibility for the circuit implementation of the charging circuit 6.

[0095] Understandably, the principle of wireless charging is mainly based on the principle of electromagnetic induction technology. Wireless charging is achieved by arranging a coil at each of the transmitting end and the receiving end. In the present utility model, a wireless charging module 106 is provided. A transmitting coil is arranged inside the wireless charging module 106. Under the action of electric power, the transmitting coil emits an electromagnetic signal to the outside world. After receiving the electromagnetic signal, the receiving coil converts it into current and voltage, thereby achieving the purpose of wireless charging.

[0096] In a wireless charging device 10 provided in this embodiment, a magnet is further placed between the receiving coil and the transmitting coil, which can play a role of central positioning. Just place the wireless charging device in the area close to the wireless charging module 106, and it can automatically charge the wireless device. It can achieve automatic adsorption without alignment and enable the wireless charging device 10 to achieve the best charging effect.

[0097] Naturally, when the user needs to use the wireless charging device 10 alone, just push the wireless charging device 10 away from the main body 11. The magnetic connection inside the main body 11 and the wireless charging device 10 will be broken, and the wireless charging device 10 can be easily removed. The charging interface 104 of the wireless charging device 10 can cooperate with other data cables with corresponding types of charging terminals for separate charging, and the function of using the wireless charging device 10 alone for wireless charging can be realized.

[0098] When the mains plug 114 is inserted into the socket and connected to the mains, the output interface 115 is connected to the mains through the charger circuit board 117 provided on the main body 11;

[0099] The other end is connected to electronic devices such as mobile phones and tablets using a data cable that conforms to the USB or USB-PD standard to achieve charging. When either the USB-A interface or the USB Type-C interface is used alone, the charging power can support a maximum fast charge of 30W.

[0100] Specifically, please refer to Figure 9 - Figure 12 The charging circuit 6 includes an input and voltage conversion control circuit 61, a fast charge output circuit 62, and a wireless charging circuit 63.

[0101] The charging circuit 6 includes an input and voltage conversion control circuit 61. The input and voltage conversion control circuit 61 includes a live wire terminal L (such as Figure 10 L in Figure 10 and a neutral wire terminal N (such as

[0102] N in Figure 11As shown in the figure, when an electronic device is connected to the output interface 115 as an output terminal, the VOUT voltage controlled by the input and voltage conversion control circuit 61 is input to the fast charging output circuit 62. The fast charging output circuit 62 includes a USB-C output module, a USB-A output module and a fast charging protocol module. The USB-C output module and the USB-A output module are respectively connected to the fast charging protocol module to achieve simultaneous fast charging of the two interfaces of the output interface 115.

[0103] At the same time, when the wireless charging device 10 serves as another output terminal to charge the wireless charging device, the wireless charging device 10 is connected to the main body 11 through the charging terminal 113 and the charging interface 104; the VOUT voltage obtained by processing through the input and voltage conversion control circuit 61 is simultaneously input to the wireless charging circuit 63. The VOUT voltage is filtered and regulated inside the wireless charging circuit 63 to form a stable 5-volt voltage that is input to the receiving end of the wireless charging device.
