[0037] The adapter plug of this application includes a network WiFi module disposed on the adapter plug for connecting to a wireless cellular network and converting the wireless cellular network traffic into WiFi traffic. It provides both conversion and charging functions, making it convenient to power or charge electronic devices, and can also provide wireless network for electronic devices, reducing the number of electronic devices that users need to carry when traveling abroad.

[0038] Example 1

[0039] like Figures 1 to 4 As shown, one embodiment of this application provides a converter plug, including a network WiFi module 200 disposed on the converter plug 100 for connecting to a wireless cellular network and converting the network traffic of the wireless cellular network into WiFi traffic.

[0040] In practice, the adapter plug 100 is a component used to connect two sockets 300 and plugs of different specifications. For example, if the socket 300 supports a plug type of category A (two-prong flat), and the plug of the electronic device is category K (three-prong round), the plug of the electronic device cannot be directly plugged into the socket 300, resulting in the inability to power or charge the electronic device.

[0041] The adapter plug 100 can solve the problem of incompatibility between sockets 300 and plugs of different specifications. For example, the adapter plug 100 is provided with both category A and category K plug terminals. The category A plug terminal of the adapter plug 100 can be plugged into sockets 300 that support category A, and the category K plug of electronic devices can be plugged into the category K plug terminal of the adapter plug 100, thus realizing the physical and conductive connection between sockets 300 and plugs of electronic devices.

[0042] In addition, the adapter plug 100 can also realize voltage conversion. For example, if the mains voltage connected to the socket 300 is 220V, while the rated input voltage of the plug of the electronic device is 110V, the adapter plug 100 can convert the 220V voltage to 110V and output it to power or charge the electronic device.

[0043] In some embodiments, the adapter plug 100 has a housing, which is typically made of an insulating material such as plastic. The circuit board and other components of the adapter plug 100 are mounted inside the housing, and the input and output terminals of the adapter plug 100 are partially exposed outside the housing.

[0044] In some embodiments, the adapter plug 100 includes a WiFi module 200, which is connected to and powered by the adapter plug 100. The WiFi module 200 can connect to the internet and wirelessly connect to the terminal device 500; that is, the WiFi module 200 can access a wireless network, convert network traffic into WiFi traffic, and then send WiFi signals to the terminal device 500.

[0045] Optionally, the network WiFi module 200 includes a card reader and a WiFi transmitter disposed within the adapter plug 100. The card reader is used to read cards to access the wireless cellular network, and the WiFi transmitter is connected to the card reader to convert the network traffic of the wireless cellular network into WiFi traffic to provide WiFi transmission signals to the terminal device.

[0046] In practice, the card reader can be a card slot, which is used to load a SIM card and access the wireless cellular network.

[0047] In some possible embodiments, the SIM card may also be a soft SIM (soft SIM card technology is to chip up the SIM card), a hard SIM, or a virtual SIM card built into the charging cable 100, without limitation.

[0048] In practice, the card reader can also be a virtual card reader. For example, the card reader can be a 3G / 4G / 5G wireless internet module. The 3G / 4G / 5G wireless internet module can access the wireless cellular network using the SIM (soft SIM or hard SIM) built into the charging cable 100, or it can access the wireless cellular network through the built-in global SIM (cloud SIM 201), and download a more suitable cloud SIM from the cloud SIM server 230 to access the wireless cellular network.

[0049] In some embodiments, the card reader and the WiFi transmitter can be integrated into a networked WiFi module 200, namely a 3G / 4G / 5G wireless internet access module with WiFi functionality. The 3G / 4G / 5G wireless internet access module connects to the base station 210 and to the core network 220 of the local operator's network. At the same time, the 3G / 4G / 5G wireless internet access module connects to the WiFi-enabled terminal device 500 via WiFi. The 3G / 4G / 5G wireless internet access module converts wireless cellular traffic into WiFi traffic and shares it with the terminal device 500.

[0050] The adapter plug 100 of this application includes a network WiFi module 200 disposed on the adapter plug 100 for connecting to a wireless cellular network and converting the network traffic of the wireless cellular network into WiFi traffic. It provides both conversion and charging functions, making it convenient to power or charge electronic devices, and can also provide wireless network for electronic devices, reducing the number of electronic devices that users need to carry when traveling abroad.

[0051] In some possible embodiments, the adapter 100 includes an adapter 110, a transformer module 120, and a first connection port 130;

[0052] The adapter 110 is used to connect to the first-specification socket 300;

[0053] The transformer module 120 is connected to the converter 110 and the network WiFi module 200, and is used to convert the AC power input to the converter 110 into DC power and output it to the network WiFi module 200;

[0054] The first connection port 130 is connected to the transformer module 120 for connection to the external device 400 to output DC power.

[0055] In practice, the adapter 110 can be regarded as the input terminal of the adapter plug 100, which is used to connect to the socket 300 to output the grid voltage connected to the socket 300 to the transformer module 120. That is, the adapter connects to the 110-230V AC power of the socket 300 and outputs it to the transformer module 120. The transformer module 120 then performs voltage conversion and outputs a suitable DC voltage, which can power the WiFi module 200 and output the DC voltage to the first connection port 130.

[0056] The first connection port 130 can be considered as the output terminal of the adapter plug 100. In some possible embodiments, there may be multiple first connection ports 130, such as at least one of USB-A interface, Type-C interface, Lightning interface, and Micro USB interface, without limitation. The transformer module 120 and any of the first connection ports 130 are connected through a VBUS (Voltage Bus) and a GND (Ground) line, so that the transformer module 120 outputs DC power to the first connection port 130.

[0057] In implementation, the first connection port 130 is used to connect to an external device 400, which can be a data cable, mobile phone, PAD, laptop, or headphones, etc., without limitation.

[0058] In some embodiments, the adapter 100 provided in this application further includes a power switching module 140 and a second connection port 150;

[0059] The transformer module 120 and the WiFi network module 200 are connected via a power switching module 140;

[0060] The power switching module 140 is also connected to the second connection port 150 and is used to switch the power supply voltage to the network WiFi module 200 according to the input voltage of the transformer module 120 and the second connection port 150.

[0061] The second connection port 150 is used to connect to an external power supply 700 or an external device 400.

[0062] In implementation, the WiFi module 200 can be powered not only by the transformer module 120 but also by an external power supply 700. The second connection port 150 and the transformer module 120 are bidirectionally connected. For example, when the second connection port 150 is connected to an external device 400, the transformer module 120 can be turned on towards the second connection port 150, allowing it to output DC voltage to the second connection port 150, which in turn powers the external device 400. When the second connection port 150 is connected to an external power supply 700 (e.g., a portable power supply, power bank, laptop, or mobile phone), the second connection port 150 can be turned on towards the transformer module 120, allowing the voltage from the external power supply 700 to be output sequentially through the second connection port 150 and the transformer module 120 to the WiFi module 200, thus powering the WiFi module 200.

[0063] Optionally, the second connection port 150 can be any one of a USB-A interface, a Type-C interface, a Lightning interface, and a Micro USB interface, without limitation.

[0064] In implementation, taking the WiFi module 200 as a 3G / 4G / 5G wireless internet access module as an example, the working principle of the power switching module 140 is as follows:

[0065] Mode 1: When the transformer module 120 has voltage output, the power switching module 140 supplies power to the 3G / 4G / 5G wireless internet module and simultaneously supplies power to the second connection port 150. At this time, regardless of whether the second connection port 150 has power input, the power switching module 140 does not respond and maintains power output.

[0066] Mode 2: When the transformer module 120 has no voltage output, if the second connection port 150 has voltage input (i.e., when the second connection port 150 is connected to the external power supply 700), the power switching module 140 outputs the external power supply 700 to the 3G / 4G / 5G wireless internet module. If the power switching module 140 detects voltage in the transformer module 120 while outputting the external power supply 700, it switches to Mode 1.

[0067] Mode 3: When both the transformer module 120 and the second connection port 150 have voltage, the voltage switching module uses the transformer module 120 to power the 3G / 4G / 5G wireless internet module. If the voltage of the transformer module 120 is lost during the power supply process, the power supply will switch to the second connection port 150 to power the 3G / 4G / 5G wireless internet module.

[0068] In some possible embodiments, the adapter 100 provided in this application further includes a third connection port 600;

[0069] The third connection port 600 connects to the adapter 110 for connection to a second-specification plug.

[0070] In implementation, the first and second specifications are any one of category A, category B, category C, category D, category E, category F, category G, category I, and category J. Category A, category B, category C, category D, category E, category F, category G, category I, and category J represent the plug specifications of various countries, for example, as shown below. Figure 2 As shown, category A has two flattened legs; as... Figure 3 As shown, category C is a flat, three-legged, figure-eight shape; as... Figure 4 As shown, category E has two round prongs. It should be noted that the first and second specifications are common plug specifications on the market, supporting American, Chinese, Australian, British, Italian, Swiss, and Brazilian standards, etc., without limitation.

[0071] With the above settings, the adapter 100 provided in this application can convert the input of the first specification to the output of the second specification, providing users with multiple options and a wider range of applications.

[0076] Those skilled in the art will clearly understand that, for the sake of convenience and brevity, the structure and implementation principle of the electrical conversion kit described above can be referred to the corresponding structure and implementation principle in the aforementioned Embodiment 1, and will not be repeated here.

[0077] The adapter plug 100 of this application includes a network WiFi module 200 disposed on the adapter plug 100 for connecting to a wireless cellular network and converting the network traffic of the wireless cellular network into WiFi traffic. This not only facilitates powering or charging electronic devices, but also provides wireless network services, reducing the number of electronic devices that users carry.
