[0043] In some embodiments, a networking WiFi module 200 is arranged in the conversion plug 100, which is connected to the conversion plug 100 and powered by the conversion plug 100 to work. The networking WiFi module 200 can be connected to a wireless network and wirelessly connected to a terminal device 500, that is, the networking WiFi module 200 can access a wireless network, and then convert network traffic into WiFi traffic and send WiFi signals to the terminal device 500.

[0044] Optionally, the networking WiFi module 200 includes a card reader and a WiFi transmitter arranged in the conversion plug 100, the card reader is used to read a card to access a wireless cellular network, and the WiFi transmitter is connected to the card reader and is used to convert network traffic of the wireless cellular network into WiFi traffic to provide WiFi transmission signals for the terminal device.

[0045] In implementation, the card reader can be a card slot, which is used to load a SIM card, and the SIM card is used to access the wireless cellular network.

[0046] In some possible embodiments, the SIM card can also be a soft SIM (soft SIM card technology is to chip the SIM card), a hard SIM, or a virtual SIM card, which is not limited.

[0047] In implementation, the card reader can also be a virtual card reader, for example, the card reader can be a 3G / 4G / 5G wireless network module, which can access the wireless cellular network by using a SIM (soft SIM or hard SIM) built in the charging cord 100, or can access the wireless cellular network by using a global SIM (cloud SIM 201) built in the charging cord 100, and download a more suitable cloud SIM from a cloud SIM server 230 to access the wireless cellular network.

[0048] In some embodiments, the card reader and the WiFi transmitter can be integrated into the networking WiFi module 200, that is, a 3G / 4G / 5G wireless network module with WiFi function, which is connected to a base station 210 through the 3G / 4G / 5G wireless network module and connected to a core network 220 of a local operator network, and at the same time, the 3G / 4G / 5G wireless network module is connected to a terminal device 500 supporting WiFi through WiFi, and the 3G / 4G / 5G wireless network module converts wireless cellular traffic into WiFi traffic and shares the WiFi traffic with the terminal device 500.

[0049] The conversion plug 100 of the present application comprises a networking WiFi module 200 arranged on the conversion plug 100 for connecting a wireless cellular network and converting network traffic of the wireless cellular network into WiFi traffic, which not only provides conversion and charging functions to facilitate power supply or charging for electronic devices, but also provides wireless network for electronic devices, thereby reducing the number of electronic devices that need to be carried by users when going abroad.

[0050] In some possible embodiments, the conversion plug 100 comprises a conversion head 110, a voltage conversion module 120 and a first connection port 130.

[0051] The conversion head 110 is used for plugging with a socket 300 of a first specification.

[0052] The voltage conversion module 120 is connected with the conversion head 110 and the networking WiFi module 200, and is used for converting alternating current input by the conversion head 110 into direct current and outputting the direct current to the networking WiFi module 200.

[0053] The first connection port 130 is connected with the voltage conversion module 120, and is used for connecting with an external device 400 to output direct current.

[0054] In implementation, the conversion head 110 can be regarded as an input terminal of the conversion plug 100, and is used for plugging with the socket 300 to output grid voltage connected by the socket 300 to the voltage conversion module 120, that is, the conversion head accesses 110-230V alternating current of the socket 300 and outputs the alternating current to the voltage conversion module 120, and then outputs appropriate direct current voltage after voltage conversion by the voltage conversion module 120, which can supply power to the networking WiFi module 200 on one hand, and can output the direct current voltage to the first connection port 130 on the other hand.

The voltage conversion module 120 and any first connection port 130 are connected through a VBUS (Voltage Bus) and a GND (ground) line, so that the voltage conversion module 120 outputs direct current to the first connection port 130.

[0056] In implementation, the first connection port 130 is used for connecting with the external device 400, which can be a data line, a mobile phone, a PAD, a notebook computer or a headset, without limitation.

[0057] In some embodiments, the conversion plug 100 provided by the present application further comprises a power switching module 140 and a second connection port 150.

[0058] The power switching module 140 is connected between the voltage transformation module 120 and the networking WiFi module 200;

[0059] The power switching module 140 is also connected with the second connection port 150, for switching the power supply voltage to the networking WiFi module 200 according to the input voltage of the voltage transformation module 120 and the second connection port 150;

[0060] The second connection port 150 is used for connecting with the external power supply 700 or the external device 400.

[0061] In implementation, in addition to being powered by the voltage transformation module 120, the networking WiFi module 200 can also be powered by the external power supply 700, wherein the second connection port 150 and the voltage transformation module 120 are in a bidirectional conduction state, for example, when the second connection port 150 is connected with the external device 400, the voltage transformation module 120 can be conducted in the direction of the second connection port 150, so that the voltage transformation module 120 outputs a direct current voltage to the second connection port 150, and then outputs to the external device 400 connected with the second connection port 150, to power the external device 400; when the second connection port 150 is connected with the external power supply 700 (such as a portable power supply, a power bank, a notebook computer or a mobile phone, etc.), the second connection port 150 can be conducted in the direction of the voltage transformation module 120, so that the voltage of the external power supply 700 is sequentially output to the networking WiFi module 200 through the second connection port 150 and the voltage transformation module 120, to power the networking WiFi module 200.

[0062] Optionally, the second connection port 150 is any one of a USB-A interface, a Type-C interface, a Lighting interface and a Micro USB interface, without limitation.

[0063] In implementation, taking the networking WiFi module 200 as a 3G / 4G / 5G wireless network module as an example, the working principle of the power switching module 140 is as follows:

[0064] Mode 1, when the voltage transformation module 120 has voltage output, the power switching module 140 delivers power to the 3G / 4G / 5G wireless network module, and at the same time, delivers power to the second connection port 150. At this time, whether the second connection port 150 has power input or not, the power switching module 140 does not respond, and keeps the power output;

[0065] Mode 2, when the voltage conversion module 120 has no voltage output, if the second connection port 150 has voltage input, that is, the second connection port 150 is connected with the external power supply 700, the power switching module 140 outputs the external power supply 700 to the 3G / 4G / 5G wireless network module. During the process of outputting the external power supply 700 by the power switching module 140, if it is detected that the voltage conversion module 120 has voltage, it is switched to mode 1;

[0066] Mode 3, when the voltage conversion module 120 has voltage, and the second connection port 150 also has voltage, the voltage switching module uses the voltage conversion module 120 to supply power to the 3G / 4G / 5G wireless network module; if the voltage of the voltage conversion module 120 is lost during the power supply process, the second connection port 150 will be switched to supply power to the 3G / 4G / 5G wireless network module.

[0067] In some possible embodiments, the conversion plug 100 provided by the application further comprises a third connection port 600;

[0068] The third connection port 600 is connected with the conversion head 110, and is used for being connected with a plug of a second specification.

[0069] In implementation, the first specification and the second specification are any one of category A, category B, category C, category D, category E, category F, category G, category I and category J. Among them, category A, category B, category C, category D, category E, category F, category G, category I and category J are plug specifications of various countries, and exemplarily, as shown in FIG. 2, category A is a double-leg flat shape; as shown in FIG. 3, category C is a three-leg eight-character flat shape; as shown in FIG. 4, category E is a double-leg round shape. It should be noted that the first specification and the second specification are common plug specifications on the market, supporting American standard, Chinese standard, Australian standard, British standard, Italian standard, Swiss standard, Brazilian standard and the like, which are not limited.

[0070] Through the above setting, the conversion plug 100 provided by the application can convert the input of the first specification into the output of the second specification, provide multiple choices for the user, and have a wider application range.
