All other embodiments, which can be derived by a person skilled in the art from the embodiments of the application described in the application without inventive step, shall fall within the scope of protection of the application.
First, a charging device according to an embodiment of the present application is described with reference to fig. 1. Fig. 1 shows a schematic block diagram of a charging device 100 according to an embodiment of the present application. As shown in fig. 1, the charging device 100 includes a detection module 110, a master processor 120, a private protocol module 130, an analog switch 140, and an interface 150. Wherein: the detection module 110 is used to detect whether the charging device 100 is connected to an ac power source or to detect a user input. The master processor 120 is configured to: when the detection module 110 detects that the charging device 100 is connected to the ac power source or detects a first user input, the analog switch 140 is controlled to connect the positive and negative data signal pins in the interface 150 to the private protocol module 130, so that the charging device 100 enters the charger mode; when the detection module 110 detects that the charging device 100 is not connected to the ac power source or detects a second user input, the analog switch 140 is controlled to connect the data positive and negative signal pins in the interface 150 to a Universal Serial Bus (USB) protocol module (not shown) in the main control processor 120, so that the charging device 100 enters a firmware upgrade mode. The firmware upgrading mode is as follows: an upgraded version of the firmware is received from a terminal connected to the interface 150 and overrides the original firmware in the master processor 120.
In the embodiment of the present application, the charging device 100 includes the detection module 110, and the detection module 110 can detect the connection condition of the charging device 100 and the ac power source. If the charging apparatus 100 is connected to the ac power source so that the charging apparatus 100 is powered on, it indicates that the charging apparatus 100 is to be used as a charger to charge the power of the ac power source to the device to be charged. If the charging device 100 is not connected to an ac power source but is also powered up, it indicates that the charging device 100 is connected to a terminal, such as a cell phone, a computer, etc., that is being powered by such a terminal. In this case, a terminal such as a mobile phone or a computer is usually in data communication with the charging device 100. In the embodiment of the present application, the analog switch 140 is provided, and the main control processor 120 controls the analog switch 140 to perform the path switching according to the two conditions: when the detection module 110 detects that the charging apparatus 100 is connected to the ac power source, the analog switch 140 may be controlled to connect a positive/negative data signal pin (generally denoted as D +/D-, as shown in fig. 2 and 3) in the interface 150 to the private protocol module 130 providing the private charging protocol, so that the charging apparatus 100 may enter a charger mode to charge the device to be charged according to the private protocol; when the detection module 110 detects that the charging device 100 is not connected to the ac power supply, the analog switch 140 may be controlled to connect the positive and negative data signal pins in the interface 150 to the USB protocol module in the main control processor 120, so that the charging device 100 may perform data communication with the terminal connected to the interface 150, thereby providing a possibility for the firmware upgrade proposed by the present application, i.e., the charging device 100 enters a firmware upgrade mode, receives a firmware upgrade version from the terminal, and covers the original firmware, thereby implementing firmware upgrade on the charging device 100 through a terminal such as a mobile phone, a computer, etc. under the conditions of plug-and-play and no need of installing a driver. The positive and negative data signal pins in the interface 150 may be connected to the USB protocol module in the main control processor 120 by default, so as to prevent the charging device 100 from being powered up when the charging device 100 is connected to a terminal such as a mobile phone or a computer.
Furthermore, in the embodiment of the present application, the user input may also be detected by the detection module 110. If a first user input is detected (the specific content of the first user input may be set as required, for example, when the detection module 110 is a key, the first user input is a short-press key, which is only an example, and any other user input representation is possible), it indicates that the user wishes the charging apparatus 100 to charge the device. If a second user input is detected (the specific content of the second user input may be set as required and may be distinguished from the first user input, for example, when the detection module 110 is a key, the first user input is a short-press key, and the second user input is a long-press key, which is only an example, and any other user input representation is possible), it indicates that the user wishes the charging apparatus 100 to perform data communication with a terminal connected to the interface 150 or perform firmware upgrade on the charging apparatus 100 through the terminal. Therefore, in the embodiment of the present application, the analog switch 140 is provided, and the analog switch 140 is controlled by the main control processor 120 to perform the path switching according to the two cases: when the detection module 110 detects a first user input, the analog switch 140 may be controlled to connect a data positive/negative signal pin (generally denoted as D +/D-as shown in fig. 2 and 3) in the interface 150 to the private protocol module 130 providing a private charging protocol, so that the charging apparatus 100 may enter a charger mode to charge a device to be charged according to the private protocol; when the detection module 110 detects a second user input, the analog switch 140 may be controlled to connect the positive and negative data signal pins in the interface 150 to the USB protocol module in the main control processor 120, so that the charging device 100 may perform data communication with the terminal connected to the interface 150, thereby providing a possibility for the firmware upgrade proposed by the present application, i.e., the charging device 100 enters a firmware upgrade mode, receives a firmware upgrade version from the terminal, and covers the original firmware, thereby implementing firmware upgrade on the charging device 100 through a terminal such as a mobile phone, a computer, etc. under the condition of plug-and-play and no need of installing a driver. The positive and negative data signal pins in the interface 150 may be connected to the USB protocol module in the main control processor 120 by default, so as to prevent the charging device 100 from being powered up when the charging device 100 is connected to a terminal such as a mobile phone or a computer.
In one embodiment of the present application, the aforementioned detection module 110 may be an alternating current-direct current (AC-DC) power module. In this embodiment, the aforementioned charging device 100 may be a charger (power adapter) that performs charging by alternating current, and therefore, the AC-DC power supply module may be used to detect whether the charging device 100 is connected to alternating current power to determine whether to control the charging device 100 to enter a charger mode or a firmware upgrade mode. In addition, the AC-DC power supply module may also be configured to output power to the device to be charged according to a control instruction of the main control processor 120, for example, after the main control processor 120 and the device to be charged perform a handshake protocol, determine a charging parameter applicable to the device to be charged, and send a control instruction based on the charging parameter, so that the AC-DC power supply module outputs appropriate power to the device to be charged.
In another embodiment of the present application, the aforementioned detection module 110 may be a key module. In this embodiment, the charging device 100 may be a mobile power supply. Accordingly, the key module may be used to detect a user input to determine whether to control the charging device 100 to enter the charger mode or the firmware upgrade mode. In addition, in this embodiment, the charging device 100 further includes a direct current-direct current (DC-DC) power supply module. The DC-DC power supply module may be configured to output power to the device to be charged according to a control instruction of the main control processor 120, for example, after the main control processor 120 performs a handshake protocol with the device to be charged, determine a charging parameter applicable to the device to be charged, and send a control instruction based on the charging parameter, so that the DC-DC power supply module outputs appropriate power to the device to be charged.
In one embodiment of the present application, the private protocol module 130 may be a chip separate from the master processor 120. In this embodiment, the private protocol module 130 is independent of the master processor 120, i.e., the master processor 120 may not need to include the private protocol module 130, and thus the structure and function may be simpler and easier to implement. In another embodiment of the present application, the private protocol module 130 may also be included in the master processor 120. In this embodiment, the master processor 120 includes both the proprietary protocol module 130 and the USB protocol module, which are relatively complex in structure and function, but may also be implemented.
In an embodiment of the present application, the master processor 120 may further include a public protocol module, such as a power output (PD) protocol module, so that the charging apparatus 100 can charge the device to be charged according to a public protocol provided by the public protocol module.
In the embodiment of the present application, the analog switch 140 may be implemented by a chip or a discrete device composed of a metal-oxide semiconductor field effect transistor (MOS transistor).
In the embodiment of the application, the upgraded version of the firmware can be pushed to the terminal by the server, so that a user does not need to pay attention to an official website to download the upgraded version, and the user experience is improved.
Generally, the charging device 100 according to the embodiment of the application can upgrade the firmware in the charging device through the terminals such as the mobile phone and the computer, so that the later-stage compatibility maintenance of the product is facilitated, the product period is prolonged, a USB-to-serial port chip is not required to be installed, and the cost is saved; in addition, when the firmware in the charging device is upgraded through terminals such as a mobile phone and a computer, the charging device is plug-and-play, a driver does not need to be installed, and the operation is convenient.

The master processor 220 may further include a master core 221 and a USB protocol module 222, wherein the master core 221 is configured to: when the AC-DC power supply module 210 detects that the charging device 200 is connected to the AC power supply, the analog switch 240 is controlled to connect the positive and negative data signal pins in the interface 250 to the private protocol module 230, so that the charging device 200 enters the charger mode; when the AC-DC power supply module 210 detects that the charging device 200 is not connected to the AC power supply, the analog switch 240 is controlled to connect the positive and negative data signal pins in the interface 250 to the USB protocol module 222 in the main processor 220, so that the charging device 200 enters the firmware upgrade mode. The firmware upgrading mode is as follows: an upgraded version of the firmware is received from a terminal connected to the interface 250 and overwrites the original firmware in the master kernel 221 with the upgraded version. In this case, the data positive and negative signal pins in the interface 250 may be connected to the USB protocol module 221 in the host processor 220 by default, so as to prevent the charging device 200 from being powered up when the charging device 200 is connected to a terminal such as a mobile phone or a computer.
In the embodiment of the present application, the charging device 200 includes an AC-DC power module 210, and the connection condition of the charging device 200 to the AC power source can be detected by the AC-DC power module 210. If the charging device 200 is connected to the ac power source so that the charging device 200 is powered on, it indicates that the charging device 200 is to be used as a charger to charge the power of the ac power source to the device to be charged. If the charging device 200 is not connected to an ac power source but is also powered up, it indicates that the charging device 200 is connected to a terminal, such as a cell phone, a computer, etc., that is being powered by such a terminal. In this case, a terminal such as a mobile phone or a computer is usually in data communication with the charging device 200. In the embodiment of the present application, the analog switch 240 is provided, and the analog switch 240 is controlled by the main control processor 220 to perform the path switching according to the two cases: when the AC-DC power module 210 detects that the charging apparatus 200 is connected to an AC power source, the analog switch 240 may be controlled to connect a positive/negative data signal pin (generally denoted as D +/D-as shown in fig. 2) in the interface 250 to the private protocol module 230 providing a private charging protocol, so that the charging apparatus 200 may enter a charger mode to charge a device to be charged according to the private protocol; when the AC-DC power supply module 210 detects that the charging device 200 is not connected to the AC power supply, the analog switch 240 may be controlled to connect the positive and negative data signal pins in the interface 250 to the USB protocol module in the main control processor 220, so that the charging device 200 may perform data communication with the terminal connected to the interface 250, thereby providing a possibility for the firmware upgrade proposed by the present application, i.e., the charging device 200 enters a firmware upgrade mode, receives a firmware upgrade version from the terminal, and covers the original firmware, thereby implementing firmware upgrade on the charging device 200 through a terminal such as a mobile phone, a computer, etc. under the conditions of plug-and-play and no need of driver installation.
In an embodiment of the present application, the aforementioned AC-DC power supply module 210 may also be configured to output power to a device to be charged according to a control instruction of the main control core 221, for example, after a handshake protocol is performed between the main control core 221 and the device to be charged, determine a charging parameter applicable to the device to be charged, and send a control instruction based on the charging parameter, so that the AC-DC power supply module 210 outputs appropriate power to the device to be charged.
In the embodiment shown in fig. 2, private protocol module 230 is a chip separate from master processor 220. In this embodiment, the private protocol module 230 is independent of the master processor 220, i.e., the master processor 220 may not need to include the private protocol module 230, and thus the structure and function may be simpler and easier to implement. In other embodiments, the private protocol module 230 may also be included in the master processor 220. In this embodiment, the master processor 220 includes both the proprietary protocol module 230 and the USB protocol module, which are relatively complex in structure and function, but may also be implemented. In an embodiment of the present application, the master processor 220 may further include a public protocol module, such as a power output protocol module (i.e., PD protocol module) 223, so that the charging apparatus 200 can charge the device to be charged according to a public protocol provided by the public protocol module.
In the embodiment of the present application, the analog switch 240 may be implemented by a chip or a discrete device composed of a metal-oxide semiconductor field effect transistor (MOS transistor).
In the embodiment of the application, the upgraded version of the firmware can be pushed to the terminal by the server, so that a user does not need to pay attention to an official website to download the upgraded version, and the user experience is improved.
