FIG. 1a is a schematic diagram of a product form of a smart stand provided by an embodiment of the present application.

As shown in FIG. 1a, the smart stand includes two interfaces, and the two interfaces can respectively support the terminal and the power supply device access; wherein, the interface C1 is used to connect with the terminal, and the interface C2 is used to connect to the power supply device. And from Figure 1a, it can be seen that the interface C1 and the interface C2 are located on the opposite side of the smart stand, but in actual applications, the position and number of the interface can be determined according to actual needs, for example: the position of the interface can also be located in the same one On the side, there may also be multiple interfaces connected to multiple terminal devices, and FIG. 1a should not be understood as limiting the number and location of the interfaces. In addition, as shown in FIG. 1a, the smart bracket can also play a supporting role.

In the embodiment of the present application, the mentioned interface may be a TYPE-C interface, a MICRO USB interface, etc., which is not specifically limited here.

FIG. 1b is a schematic diagram of an application scenario of a smart stand provided by an embodiment of the present application.

As shown in FIG. 1b, the interface C1 in FIG. 1a may be used to connect a terminal, and the interface C2 may be used to connect a power supply device. In this application scenario, the terminal is a tablet computer and the power supply device is a charger. Of course, in practical applications, the terminal can also be a mobile phone, personal digital processing (personal digital ssistant, PDA) and other devices.

FIG. 2a is a schematic structural diagram of a smart stand provided by an embodiment of the present application.

As shown in FIG. 2a, an embodiment of the smart stand provided by the embodiment of the present application may include:

The first interface 201, the second interface 202, and the communication chip 203; the first interface 201 is connected to the terminal, and the second interface 202 is connected to the power supply device.

When the power supply device supplies power to the terminal through the power supply line between the second interface 202 and the first interface 201, the communication chip 203 receives the access signal sent by the terminal, and the access signal is used by the terminal to obtain the identity (ID) information of the smart stand. In this way, when the ID information matches the preset identification information in the terminal, the terminal starts the target mode.

In the embodiment of the present application, the first interface of the smart stand is mainly an uplink port or a male connector connected to the terminal. The mentioned terminal may be a smart device such as a tablet or a mobile phone, which is not specifically limited here.

The second interface is mainly a downstream port or a female head connected to a power supply device. The power supply device mentioned may be a device such as a fast charge (PD) charger that can output voltage externally, which is not specifically limited here.

The smart bracket also includes a communication chip, which may be an electronic mark chip (electronic mark: ic: E-MARK) or a single-bus communication IC chip, which is mainly used for data communication with the terminal, and is not specifically limited. .

In the embodiment of the present application, when the power supply device is connected to the smart support through the second interface, the power supply device outputs a power supply voltage, so that the terminal can be powered. The line used by the power supply device to supply power to the terminal may be directly powered by the power line between the second interface and the first interface. The purpose of the power supply device to supply power to the terminal is to enable the terminal to output an access signal to the communication chip, which can be used as a prerequisite for the terminal to initiate access to the communication chip.

Since the related information of the smart stand is already stored in the communication chip, such as ID information, data transmission capability information, etc., after the communication chip receives the access signal sent by the terminal, the communication chip can obtain the intelligence according to the access signal The ID information of the bracket is fed back to the terminal, so that the terminal can obtain the ID information, which identifies the identity information of the corresponding smart bracket, such as: vendor identity ID information (vendor identity: Vendor ID), product identity Identifying ID information (product identity: Product ID), etc., which can identify the identity information of the smart stand, the specific is not limited here. In this way, when the ID information matches the preset identification information, the terminal can recognize that this is not a bracket that only involves support, but an intelligent bracket that can enter a certain working mode, that is, it can start the target mode. For example, it can be automatically called the first installation package APK, or automatically called the first application and other working modes; it can also be automatically called the voice assistant. It should be noted that the first application mentioned above may be an application APP such as WeChat, video player, camera, etc., which is not specifically limited.

For example: suppose the startup target mode is to automatically call the voice assistant. When the terminal determines that the ID information of the smart stand matches the preset identification information, and the preset identification information is associated with the voice assistant, the terminal will automatically call the assistant Voice assistant, which can control the startup of installed software through voice commands.

It is also assumed that the startup target mode may be to automatically call the WeChat APP. If the terminal determines that the ID information of the smart stand matches the preset identification information, the terminal will automatically start a pre-defined operation, and set in the pre-defined operation It is determined that the preset identification information is associated with the WeChat APP, so that the terminal can automatically call the target mode of WeChat APP; otherwise, if the terminal does not match the ID information and the preset identification information, then it will not start this Operation, naturally will not automatically call the WeChat APP mode. Therefore, when the ID information matches the preset identification information, the terminal can automatically call the target mode associated with the smart stand, which improves the efficiency of mode startup.

FIG. 2b is a display diagram of a terminal interface provided by an embodiment of the present application.

Optionally, based on the above embodiment corresponding to FIG. 2a, as shown in FIG. 2b, the power supply device is connected to the smart stand, and the smart stand is connected to the terminal, assuming that the preset operation set by the terminal at this time is WeChat APP Associated with the smart stand, then from the terminal's interface, it can be seen that the terminal can automatically call WeChat after connecting the smart stand.

In the embodiment of the present application, the communication chip 203 obtains and feeds back the ID information of the smart stand by receiving the access signal of the terminal, so that only the communication between the communication chip and the terminal can enable the terminal to automatically start the target mode without communicating with the power supply device , Which simplifies the circuit structure of the smart bracket, reduces costs, and improves the efficiency of mode startup.

In this technical solution, for different communication chips, the internal circuit structure of the smart bracket is also different. Therefore, in this embodiment of the present application, two different types of chips are used as examples to introduce the structure of the smart bracket.

Two different types of chips to be described in the embodiments of the present application, one is a chip that requires a power supply device to supply power for it to work, and one is a chip that can work without power supply from a power supply device.

1. For a smart stand using a chip that requires a power supply device to supply power to it, the embodiment of the present application will be described with reference to FIGS. 3 to 5.

FIG. 3 is another schematic structural diagram of a smart stand provided by an embodiment of the present application.

Optionally, based on the above embodiment corresponding to FIG. 2a, as shown in FIG. 3, another embodiment of the smart stand provided by the embodiment of the present application may further include: a voltage regulator 301, and the communication chip 203 includes a first In the chip 2031, the first interface module 201 includes a first pin 2011, one end of the voltage regulator 301 is connected to the second interface 202, the other end is connected to the first chip 2031, and the first chip 2031 is connected to the first pin 2011.

When the power supply device is connected to the second interface 202, the first chip 2031 is powered by the voltage regulator 301.

The first chip 2031 receives the access signal sent by the terminal through the first pin 2011.

This embodiment is based on the embodiment described in FIG. 2a. When the power supply device is connected to the smart stand through the second interface, the output power voltage can be adjusted by the voltage regulator to be stable and suitable for the first The voltage at which the chip 2031 starts to work, such as 3.3V, which is not specifically limited here, so that the first chip 2031 starts working after receiving power from the power supply device, so that the powered first chip 2031 can supply power to the terminal at the power supply device At the same time, the access signal sent by the terminal is received through the first pin. As shown in FIG. 2a, the access signal is actively sent by the terminal to the first chip 2031 to request and obtain ID information of the smart stand. Therefore, only the communication between the first chip and the terminal can enable the terminal to automatically call the target mode, which improves the efficiency of mode startup, and the smart bracket does not need to communicate with the power supply device, simplifying the circuit structure of the smart bracket and reducing the cost.

In this embodiment, the voltage regulator described may be a voltage regulator, a linear regulator (LDO), or other similar components that can be used for voltage regulation, which is not specifically limited here.

FIG. 4 is another schematic structural diagram of a smart stand provided by an embodiment of the present application.

Optionally, based on the above embodiment corresponding to FIG. 3, as shown in FIG. 4, another embodiment of the smart bracket provided by the embodiment of the present application may further include: a first pull-up resistor 401 and a second pull-up Resistor 402, the first interface 201 further includes a second pin 2012.

The first pin 2011 is connected to the power supply line described in FIG. 2a through the first pull-up resistor 401, so that the terminal detects the first voltage between the first pin 2011 and the power supply line, and the second pin 2012 passes the second The pull-up resistor 402 is connected to the power supply line described above in FIG. 2a, so that the terminal detects the second voltage between the second pin 2012 and the power supply line.

The first chip 2031 receives the access signal sent by the terminal through the first pin 2011 when the terminal determines that both the first voltage and the second voltage reach the target voltage.

In this embodiment, the first pin is connected to the power supply line described in FIG. 2a through the first pull-up resistor, and the power supply line is after the power supply device is connected to the smart bracket and passes between the second interface and the first interface The power supply line provides power to the terminal. Therefore, while the power supply device outputs the power supply voltage and supplies power to the terminal through the power supply line, the first pull-up resistor has a voltage dividing function, which can cause the terminal to detect the first pin and The voltage between the power supply lines is the first voltage mentioned above. Generally, the resistance value of the first pull-up resistor is 22 kohm (kohm: kiloohm). In actual applications, there may be other resistance values with similar effects, which are not specifically limited here. Similarly, the second pin is connected to the power supply line described in FIG. 2a through the second pull-up resistor. Therefore, while the power supply device outputs the power supply voltage and supplies power to the terminal through the power supply line, the second pull-up resistor also With the function of voltage division, the terminal can detect the voltage between the second pin and the power supply line, that is, the second voltage mentioned above. Generally, the resistance value of the second pull-up resistor is also 22 kohm. In actual applications, there may be other resistance values with similar functions, which are not limited here.

Therefore, after detecting the first voltage and the second voltage, the terminal needs to determine and determine whether the detected first voltage and second voltage both reach the target voltage, such as 1.5V, which is not specifically limited here. The main purpose of this is to first make an initial judgment on whether the smart stand is connected to the terminal. If the terminal detects that both the first voltage and the second voltage have reached the target voltage, it indicates that the terminal can be connected. It is used to start the smart bracket of the associated target mode; conversely, if the terminal detects that both the first voltage and the second voltage have not reached the target voltage, it indicates that the terminal may be connected to a common peripheral bracket at this time, such as: Headphones, etc., no specific restrictions.

Since the first chip 2031 is connected to the first pin in the first interface, when the terminal accesses the smart stand through the first interface, then the connection between the first pin and the first chip 2031 forms the first A link for data communication between the chip 2031 and the terminal.

Based on the embodiment corresponding to FIG. 3 above, the first chip 2031 can start working after receiving power from the power supply device through the voltage regulator. Therefore, the first chip 2031 in the working state determines the first voltage and the second voltage at the terminal. When both reach the target voltage, you can receive the access signal sent by the terminal through the first pin while the power supply device is supplying power to the terminal. The access signal is the terminal actively sends the first chip 2031 after determining the connection with the smart bracket Sent to request and obtain the ID information of the smart stand.

Since the first chip 2031 already stores related information of the smart stand, such as ID information, data transmission capability information, etc., after the first chip 2031 receives the access signal sent by the terminal, it can be extracted according to the access signal The ID information of the smart stand is fed back to the terminal, so that the terminal can obtain the ID information, which is the identity information that identifies the corresponding smart stand, so the terminal can recognize from the ID information that this is not usually involved It is only a bracket with a supporting function, but an intelligent bracket that can enter a certain working mode, which is understood by referring to the schematic diagram of the scene described in FIG. 2b. Therefore, only the communication between the first chip and the terminal can enable the terminal to automatically call the target mode, which improves the efficiency of mode startup, and the smart bracket does not need to communicate with the power supply device, simplifying the circuit structure of the smart bracket and reducing the cost.

The first pin and the second pin in the first interface in FIGS. 3-4 can be CC pins, that is, CC1_U and CC2_U, which can enable signal transmission between the first chip and the terminal.

FIG. 5 is another schematic structural diagram of a smart stand provided by an embodiment of the present application.

Optionally, based on the above embodiment corresponding to FIG. 4, as shown in FIG. 5, another embodiment of the smart stand provided by the embodiment of the present application may further include a first pull-down resistor 501 and a second pull-down resistor 502 The second interface 202 includes a third pin 2021 and a fourth pin 2022.

The third pin 2021 is grounded through the first pull-down resistor 501, and the fourth pin 2022 is grounded through the second pull-down resistor 5022, so that the power supply device outputs a voltage.

In this embodiment, when the power supply device is connected to the second interface, it can output voltage and supply power to the terminal through the power supply lines as shown in FIG. 2a, FIG. 3, and FIG. 4, and the voltage regulator of FIG. 3 is the first The chip 2031 supplies power, so the third pin and the fourth pin of the second interface need to be grounded through the first pull-down resistor and the second pull-down resistor, respectively, so that the power supply device can recognize the third pin and the fourth pin The grounded low level, thereby outputting the power supply voltage, eliminates the high impedance input. Generally, the resistance value of the first pull-down resistor and the resistance value of the second pull-down resistor are 5.1 kohm. In actual applications, there may be other resistance values with similar functions, which are not limited here.

It should be noted that the third pin and the fourth pin in the second interface in this embodiment may be CC pins, namely CC1_D and CC2_D, which can enable the power supply device to configure the power supply voltage Vbus.

The first chip 2031 and the first interface and the second interface described in FIG. 2a, FIG. 3, and FIG. 4, it should be noted that since the first chip 2031 does not store power, the power supply device needs to be One chip 2031 supplies power, which may be an E-MARK IC chip or a chip similar to the E-MARK IC chip for data communication with a terminal, which is not limited in this embodiment; and the first interface and the second interface It is mainly a TPYE-C interface, but there are many similar interfaces in practical applications, which are not limited in the embodiments of the present application.

Therefore, when the power supply device supplies power to the terminal through the power supply line as described above in FIG. 2a, the second chip 2032 can receive the access signal sent by the terminal through the ID pin while the power supply device supplies power to the terminal, so that the terminal can Used to request and obtain the ID information of the smart stand.

Since the second chip 2032 already stores the relevant information of the smart stand, such as ID information, data transmission capability, etc., after the second chip 2032 receives the access signal sent by the terminal, the second chip 2032 can use the access The signal extracts the ID information of the smart stand and feeds it back to the terminal, so that the terminal can obtain the ID information. The ID information identifies the identity information of the corresponding smart stand, so the terminal can recognize this based on the ID information. This is not usual. What is involved is only a bracket with a supporting function, but an intelligent bracket that can enter a certain working mode, which is understood with reference to the scene schematic diagram described in FIG. 2b. Therefore, only the communication between the second chip and the terminal can make the terminal automatically call the target mode, which improves the efficiency of mode startup, and the smart bracket does not need to communicate with the power supply device, simplifying the circuit structure of the smart bracket and reducing the cost.

The second chip 2032 receives the access signal sent by the terminal through the ID pin 2013 when the chip of the terminal detects that the voltage between the ID pin 2013 and the GND pin 2014 reaches the target voltage.

In this embodiment, since the ID pin and the GND pin of the first interface are both connected to the chip in the terminal, such as a soc chip, the chip of the terminal can detect the two pins of the ID pin and the GND pin Voltage range between. Therefore, if the terminal chip detects the voltage interval between the ID pin and the GND pin, the terminal chip needs to determine and determine the detected ID pin and GND pin. Whether the voltage interval between the feet has reached the target voltage, such as: 1.5V-1.7V, the specific is not limited here.
