[0019] In order to make the purpose, technical solution and advantages of the embodiments of the present application clearer, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of this application.
[0020] The disclosure below provides many different embodiments or examples to implement different structures of the present invention. In order to simplify the disclosure of the present invention, the parts and settings of specific examples are described below. Of course, they are only examples, and the purpose is not to limit the present invention. In addition, the present invention can repeat reference numbers and / or letters in different examples. This repetition is for the purpose of simplification and clarity, and does not itself indicate the relationship between the various embodiments and / or settings discussed.
[0021] Figure 1 A power adapter is provided in an embodiment of the present application, such as Figure 1 As shown, the power adapter includes: a power module 11, a network module 21 and a universal serial bus USB interface 31; wherein the network module 21 includes a baseband processor 211, a SIM card 212, a power management module 213 and a radio frequency module 214;
[0022] The SIM card 212 is connected to the baseband processor 211, and the first end of the baseband processor 211 is connected to the data pin of the USB interface 31 to form a data path; the second end of the baseband processor 211 is connected to the radio frequency module 214; wherein the data path is used to provide a network signal to the terminal based on the baseband processor 211 when the USB interface 31 is connected to the terminal;
[0023] A first end of the power management module 213 is connected to a third end of the baseband processor 211, a second end of the power management module 213 is connected to a power supply pin of the USB interface 31 to form a first power supply path, and a third end of the power management module 213 is connected to the power module 11 to form a second power supply path, wherein the first power supply path is used to supply power to the network module 21 through the terminal when the power module 11 is not connected to a power source and the USB interface 31 is connected to the terminal, and / or the first power supply path is used to supply power to the network module 21 and / or the terminal through the power source when the power module 11 is connected to a power source and the USB interface 31 is connected to the terminal; the second power supply path is used to supply power to the network module 21 and / or the terminal through the power source when the power module 11 is connected to a power source.
[0024] It should be noted that the baseband processor 211 in the power adapter in the embodiment of the present application can obtain 2G network signals, 3G network signals, 4G network signals, 5G network signals, etc. based on the SIM card 212. Specifically, if the 2G network signal is obtained, the network signal of the GSM (Global System for Mobile Communications, GSM, Global System for Mobile Communications) is obtained, and if the 3G network signal is obtained, the network signal of the CDMA (Code Division Multiple Access) system is obtained. The 4G network signal and the 5G network signal are also processed in a similar manner. Therefore, in the embodiment of the present application, network signals (2G network signals, 3G network signals, 4G network signals, 5G network signals, etc.) can be provided to the terminal connected to the USB interface 31 based on the SIM card 212 and through the data path, so that the power adapter can provide network signals to the terminal without using the signal of the public network.
[0025] It can be seen that in the embodiment of the present application, the power adapter includes a USB interface 31, through which a first power supply path and a second power supply path are formed, that is, when the power supply is not connected, the network module 21 can be powered by the terminal, and when the power supply is connected, the network module 21 and / or the terminal can be powered by the power supply. Furthermore, since the power adapter has a built-in SIM card 212, it can be seen that the power adapter can provide a network signal to the terminal regardless of whether it is through the first power supply path or the second power supply path. Even when the terminal is on a business trip or in a mobile office scenario, it can use a network with a higher security, avoiding the use of a public Wi-Fi network or a shared wired network, and solving the problem in the prior art that only a shared network can be used in a business trip or mobile office scenario, resulting in poor network security.
[0026] It should be noted that the USB interface 31 in the embodiment of the present application can be a Type-C interface. Of course, if it is another USB interface 31 that can provide a data path and a power supply path as in the present application, it is also within the protection scope of the present application. In addition, the power supply in the embodiment of the present application can be a mains power supply.
[0027] In addition, the SIM card 212 in the embodiment of the present application can be an eSIM card in a specific example; the eSIM card is embedded in the chip of the baseband processor 211, and the space occupied by the eSIM card is only 1 / 3 of that of the Nano SIM card, which can effectively reduce the layout space. Since there is no need to insert a physical SIM card, it is convenient for users to switch operators and packages. The eSIM card does not require a card slot carrier and a patch welding process, and directly embeds the function of the SIM card into the chip. It can be seen that the eSIM card has the advantages of reduced size, high stability, one number for multiple terminals, and convenient use.
[0028] In an optional implementation manner of the embodiment of the present application, if Figure 2 As shown, the network module 21 in the embodiment of the present application may also include a WiFi module 215;
[0029] The WiFi module 215 is connected to the fourth terminal of the baseband processor 211 for WiFi communication with the terminal through the SIM card 212. Further, the WiFi module 215 includes a WiFi processor 216, a WiFi front end 217 and a WiFi antenna 218.
[0030] In a specific example, the fourth end of the baseband processor 211 in the present application is connected to the first end of the WiFi processor 216, the second end of the WiFi processor 216 is connected to the first end of the WiFi front end 217, and the second end of the WiFi front end 217 is connected to the WiFi antenna 218; wherein, the WiFi processor 216, the WiFi front end 217 and the WiFi antenna 218 in the WiFi module 215 perform WiFi communication with the terminal based on the SIM card 212 connected to the baseband processor 211.
[0031] In the embodiment of the present application, the WiFi module 215 is connected to the baseband processor 211, so the baseband processor 211 can provide a network signal for the WiFi module 215 based on the SIM card 212. Based on this, the WiFi module 215 can serve as a relay point to provide WIFI signals to other terminals.
[0032] It can be seen that the power adapter in the embodiment of the present application can not only provide network signals to the terminal connected to the USB interface 31 through the SIM card 212, but also provide network signals to other terminals based on the WiFi module 215. That is to say, in a specific example, the power adapter in the embodiment of the present application can only provide network signals to one or more terminals wirelessly connected thereto through the WiFi module 215, and at the same time, in order to ensure the stable transmission of network signals, it can also provide network signals to the terminal connected to the power adapter through the USB interface 31. Compared with the shared network in a public environment, the network signal provided by the power adapter is safer and more stable.
[0033] In an optional implementation manner of the embodiment of the present application, if Figure 3 As shown, the network module 21 in the embodiment of the present application further includes a battery 219;
[0034] The battery 219 is connected to the power management module 213; when the power module 11 is connected to a power source and supplies power to the network module 21 through the power source, the power source charges the battery 219. When the power module 11 is not connected to a power source, the battery 219 supplies power to the network module 21 and / or to the terminal based on the power management module 213; or, when the power module 11 is not connected to a power source, the terminal supplies power to the battery 219 based on the power management module 213.
[0035] It can be seen that the power adapter in the embodiment of the present application also has a built-in battery 219, which can be charged by the power supply when the power adapter is connected to the power supply. When the power adapter is not connected to the power supply, if the current power of the battery 219 is sufficient, it can supply power to the network module 21 or to the terminal through the first power supply path. If the current power of the battery 219 is insufficient, the terminal can supply power to the battery 219 through the first power supply path. In a specific example, if the power adapter cannot be connected to the power supply or is in a power outage state in the current environment, the power adapter can supply power to the terminal connected thereto based on the battery 219, and can also supply power to the network module 21. Therefore, even if the power adapter is not connected to the power supply, the network signal can still be provided to the terminal through the power adapter.
[0036] In an optional implementation manner of the embodiment of the present application, if Figure 4 As shown, the power adapter in the embodiment of the present application also includes a display screen 41; the display screen 41 is used to display status information; wherein the status information includes at least one of the following: network status information, power information, working status information of the power adapter, and time information.
[0037] It can be seen that the current power adapter status can be further obtained through the display screen 41, such as the amount of power, whether the network signal is stable, etc. Based on this, it can be determined whether to charge the power adapter, or to adjust the network signal by changing the position of the power adapter, or if the WiFi signal is not needed, the WiFi signal can be turned off by operating on the display screen 41, reducing the power consumption of the device and saving energy to improve the user experience. It should be noted that the display screen 41 in the embodiment of the present application can be connected to the network module 21 so that the status information to be displayed can be directly obtained.
[0038] In an optional implementation manner of the embodiment of the present application, if Figure 5 As shown, the RF module 214 in the embodiment of the present application includes: an RF transceiver 220, an RF front end 221 and an RF antenna 222; wherein the baseband processor 211 is connected to the first end of the RF transceiver 220, the second end of the RF transceiver 220 is connected to the first end of the RF front end 221, and the second end of the RF front end 221 is connected to the RF antenna 222.
[0039] The radio frequency module 214 in the embodiment of the present application realizes communication in the cellular network through the SIM card 212, and can further provide a network signal for the terminal connected to the power adapter.
[0040] In an optional implementation manner of the embodiment of the present application, if Figure 6 As shown, the power adapter also includes a fast charging protocol module 51; wherein, the first end of the fast charging protocol module 51 is connected to the power module 11, and the second end of the fast charging protocol module 51 is connected to the USB interface 31, wherein the fast charging protocol module 51 is used to fast charge the terminal connected to the USB interface 31 when the power adapter is connected to a power source.
[0041] It can be seen that in the embodiment of the present application, the network module 21 and / or the terminal connected to the USB interface 31 can be fast charged through the fast charging protocol module, specifically, the fast charging scale can be 40W or 60W, and the specific fast charging scale can be set accordingly according to actual needs.
[0042] In an optional implementation of the embodiment of the present application, the power adapter in the embodiment of the present application may also include a first switch and a second switch, wherein the first switch is connected to the baseband processor 211, and the second switch is connected to the WiFi module 215, and the first switch is used to turn on or off the network of the SIM card 212, that is, if the current terminal does not need the SIM card to provide a network signal (such as in an office or home environment), the network of the SIM card can be turned off by the first switch to reduce the power consumption of the power adapter, and when outdoors or without a network, the network of the SIM card 212 can be turned on by the first switch. The second switch is used to turn on or off the WiFi module 215, that is, if there is no need to provide a WiFi signal to other devices at present, the WiFi module 215 can be turned off by the second switch to reduce the power consumption of the power adapter, and when it is necessary to provide a WiFi signal to other devices, the WiFi module 215 can be turned on by the second switch to provide a WiFi signal to other devices to provide a safe and convenient network environment.
[0043] In an optional implementation of the embodiment of the present application, the power module 11 may include: an input filter, a power factor correction module, a power switch, a transformer, a control module, a power feedback and an output filter;
[0044] Among them, the power factor correction module is connected to one end of the power switch, the other end of the power switch is connected to one end of the transformer, and the other end of the transformer is connected to the output filter; one end of the input filter is connected to one end of the control module, the other end of the control module is connected to one end of the power feedback, and the other end of the power feedback is connected to the transformer.
[0045] It should be noted that the power factor correction module is used to correct the power factor, because too small a power factor wastes the capacity of the power supply equipment, and therefore needs to be corrected. The power factor refers to the ratio of the active power of the AC circuit to the apparent power. The input filter is used to suppress the conducted interference and radiated interference generated by the inverter; the output filter is used to filter out the high-order harmonics in the inverter output current, reduce the additional torque caused by high-frequency harmonics, reduce the motor temperature rise and motor operation noise, and suppress the surge voltage on the output side of the inverter, thereby improving the power factor of the variable frequency speed regulation system.
[0046] The power adapter based on the above-mentioned embodiment of the present application can be used in the following usage scenarios in specific examples:
[0047] Scenario 1) When the power adapter is connected to the mains, the USB cable is used to connect the computer (terminal) at the same time. This can charge the computer and provide the computer with network access via a wired connection.
[0048] After the power adapter is connected to the mains, the fast charging protocol module 51 is connected to a specific pin of the USB Type C interface 31 (such as a CC signal, etc.), and then the computer (terminal) is charged through the power supply pin of the USB Type C interface 31 (such as a VBUS signal). At the same time, the power module 11 outputs a separate power supply (a second power supply path) to the power management of the network module 21 to power the network module 21. The USB data interface of the baseband processor 211 of the network module 21 is connected to the data part of the USB Type C interface 31 (such as a USB2.0 or USB3.0 data signal) through a data path to realize the function of Internet data interaction between the computer and the network module 21.
[0049] Scenario 2) When the power adapter is connected to the mains, the computer (terminal) is connected with a USB cable at the same time, which can charge the computer while providing network access to the computer through a wired connection, and at the same time provide network access to other electronic devices through the WiFi module 215.
[0050] After the power adapter is connected to the mains, the computer is charged based on the connection between the fast charging protocol module 51 and the specific pins of the USB Type C interface 31 (such as CC signals, etc.), and then the power supply pins of the USB Type C interface 31 (such as VBUS signals). At the same time, the power module 11 outputs a separate power supply (second power supply path) to the power management of the network module 21 to power the network module 21. The USB data interface of the baseband processor 211 of the network module 21 is connected to the data part of the USB Type C interface 31 (such as USB2.0 or USB3.0 data signals) through the data path, realizing the function of Internet data interaction between the computer and the network module 21.
[0051] After the SIM card 212 is connected to the baseband processor 211, the baseband processor 211 communicates with the cellular network through the RF transceiver 220, the RF front end 221 and the RF antenna 222. Similarly, the baseband processor 211 can also communicate with other WiFi terminal devices connected to the network module 21 through the WiFi processor 216, the WiFi front end 217 and the WiFi antenna 218.
[0052] Scenario 3) When the power adapter is not connected to the mains and is connected to a computer via a USB cable, the computer can power the power adapter device and provide network access to the computer via a wired connection, and at the same time provide network access to other electronic devices via the WiFi module 215.
[0053] Specifically, the power adapter is connected to a specific pin (such as CC signal, etc.) of the USB TypeC interface 31 based on the protocol fast charging module 51, and the computer provides power to the power management part of the network module 21 through the power supply pin of the USB TypeC interface (such as VBUS signal). At the same time, the USB data interface of the baseband processor 211 of the network module 21 is connected to the data part of the USB TypeC interface 31 (such as USB2.0 or USB3.0 data signal) through the data path, realizing the function of Internet data interaction between the computer and the network module 21.
[0054] Scenario 4) When the power adapter is connected to the mains and no USB cable is used, the computer can access the Internet via WiFi connection to the power adapter device and provide network access to other electronic devices via WiFi module 215.
[0055] Specifically, after the power adapter is connected to the mains, the power module 11 in the power adapter outputs a single power supply (a second power supply path) to the power management module 213 of the network module 21 to supply power to the network module 21 .
[0056] Scenario 5) The power adapter is not connected to the mains, and the built-in battery 219 of the power adapter supplies power to the power adapter device, and provides network access to various electronic devices through the WiFi module 215.
[0057] Specifically, when the power adapter is not connected to the mains, the network module 21 is powered by the built-in battery 219. If necessary, if the current battery power is low and the power adapter is not connected to a power source, the terminal can also power the battery 219 based on the USB Type C interface. Similarly, if the current terminal power is low and the power adapter is not connected to a power source, the battery 219 in the power adapter can also power the terminal based on the USB Type C interface.
[0058] It can be seen that the power adapter of the present application can provide network access to the computer through wired or WiFi, and can also provide network access to other network electronic devices through WiFi. This not only facilitates the user experience during computer use, but also enhances the security of the user's use of the network.
