Detailed Description

In order to make the objects, technical solutions and advantages of the embodiments of the present application more clear, the technical solutions of the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application.

It will be appreciated that the interface in the terminal device is for connection with at least one external device. The terminal device can realize different functions through various interfaces arranged inside. For example, the terminal device may perform data communication with other external devices based on the USB interface, or may connect to other external devices or power sources through the USB interface to charge the terminal device; the terminal device can transmit video signals and the like with other external devices based on the HDMI interface; the terminal device may be connected to the local area network based on a network interface. Among these interfaces, the USB interface is the most widely used interface on terminal devices, and is already present in various terminal devices.

However, the greater the number of interfaces in the terminal device corresponding to different functions, the greater the volume of the terminal device, and the thicker the whole.

In view of this, the present application discloses a terminal device. In the terminal device, the interface of partial functions can be arranged in the form of an external connection component. For example, as shown in fig. 1A, the USB female interface 124 is reserved on the terminal device 100. And an HDMI interface or a network interface, etc., which is not provided on the main body of the terminal device 100 but on the external connection part 130, is not shown in fig. 1A. And then the external connection part 130 is respectively connected with the USB female interface 124 and the external device 200 to realize the connection and signal transmission between the terminal device 100 and the external device 200. Also, as shown in fig. 1B, the external connection part 130 may include a USB male interface 131, a connection module 132, and a second male interface 133. The second male interface 133 may include an HDMI male interface or a network interface, which is not shown in fig. 1B.

Meanwhile, in order to enable the terminal device 100 to recognize the type of the connected external device 200 or recognize the type of the second male interface 133 having a function other than the USB interface function provided on the external connection part 130 so that the terminal device 100 can perform signal transmission of a corresponding function with the external device 200, referring to fig. 1B, the signal selection module 120 and the control module 123 may be provided inside the terminal device 100. The signal selection module 120 may be configured to send a signal corresponding to the type of the external device 200, which is sent by the processor in the terminal device 100, to the USB female interface 124. The control module 123 may be configured to identify the type of the external device 200 according to the level signal transmitted to the USB female interface 124 by the external connection unit 130, and send a signal corresponding to the type of the external device 200 sent by the processor to the USB female interface 124 by controlling the selector through an instruction.

In one possible implementation, the external device detection pin in the USB male interface 131 of the external connection component 130 may be connected to the ground pin through a resistor. As shown in fig. 1B, when the USB female interface 124 and the USB male interface 131 are connected, the USB male interface 131 in the external connection component 130 may send a level signal of the external device detection pin to the USB female interface 124. When receiving the level signal of the external device detection pin sent by the USB female interface 124, the control module 123 identifies the type of the external device 200, and sends an instruction to the selector to send a signal corresponding to the type of the external device 200 sent by the processor to the USB female interface 124. So that the terminal device 100 can perform correct signal transmission with the external device 200.

The terminal equipment can reduce the number of interfaces on the terminal equipment under the condition that the terminal equipment keeps a plurality of interface functions, thereby reducing the volume and the weight of the terminal equipment. In addition, as the size of the USB female interface is usually smaller, the USB interface is adopted on the terminal equipment to replace interfaces with other functions, and the volume and the weight of the terminal equipment can be further reduced.

The following describes the technical solution of the present application in detail based on fig. 2 to 8.

First, referring to fig. 2 to 4, the structures of the plurality of interfaces, including the USB interface, the HDMI interface, and the network interface, involved in the embodiments of the present application are described.

It can be understood that the USB interface is used as an input/output interface for connecting the terminal device with an external device, a power supply, a charger, etc., so that the connection and communication functions with the external device can be realized, and the terminal device can be charged or signal transmitted through the USB interface.

The USB Type C interface, i.e. the USB Type C interface, has the greatest external characteristics that the upper and lower ends of the USB Type C interface are completely consistent and have no directivity in use, and can provide a maximum transmission rate of up to 80Gbps, so that the USB Type C interface meets the requirement of a user for transmitting a large capacity, and has a faster transmission rate and a shorter transmission time. In addition, the size of the USB Type C interface is smaller than the interface size of other USB specifications at present, so the port of the USB Type C interface is smaller than the ports of the USB interfaces of other specifications, and therefore, the setting of the USB Type C interface on the terminal device is also more and more popular.

Referring to fig. 2, the structure of the USB Type C interface is described first.

As shown in fig. 2, the USB Type C interface includes 24 pins, A1 to a12, and B1 to B12, respectively. The pins A1 to A12 are sequentially identical to the pins B1 to B12 in function, and provide a basis for not distinguishing the forward and reverse directions of the insertion of the USB Type C interface. The function of each pin is described below by taking pins A1 to a12 as an example.

Pins A1, a12: ground (GND) pin.

Pins A2, A3: the data transmit (transmit exchange, TX) pin may be used to be compatible with protocol USB3.0 and protocol USB3.1. Wherein, pin A2 may be a TX0 pin and pin A3 may be a TX1 pin.

The DFP device may be used to provide VBUS and/or to provide data, and the UFP device may be used to take power from the DFP device and/or to provide data. Illustratively, the power adapter may be a DFP device, and the usb disk and the removable hard disk may be UFP devices. The pin A5 can also be used for detecting the insertion direction of the USB Type C plug, and establishing a route of the USB data channel according to the insertion direction; discovering and configuring VBUS, wherein VBUS is a power line for supplying power to the USB slave device by the USB master device, and configuring PD power supply mode of the USB interface; optional standby and auxiliary modes are discovered and configured.

Pins A6, A7: the data transmission (data, D) pin can be used for transmitting audio and video streams or files and the like. Wherein, pin A6 may be a D+ pin and pin A7 may be a D-pin.

Among them, pin A2, pin A3, pin a10, pin a11, and corresponding pins B2, B3, B10, and B11 may be used to transmit high-speed minimized transmission differential signals (transition minimized differential signal, TMDS). Pins A6 and A7, and corresponding pins B6 and B7, are used for transmitting low-speed TMDS signals.

In one possible implementation, the transmission rate of the high-speed signal described in the context of the embodiments of the present application may generally reach the category of metering in GHz; the transmission rate of low-speed signals can generally reach the range of metering in MHz, but not GHz. In the embodiments of the present application, the transmission rates of the high-speed signal and the low-speed signal are not particularly limited.

It can be appreciated that when the cable with the USB Type C plug is connected to the USB Type C interface on the terminal device, pins in the USB Type C plug are connected to pins in the USB Type C interface of the terminal device 100 in a one-to-one correspondence, for example, pin A1 in the USB Type C plug is connected to pin A1 in the terminal device 100, pin A2 in the USB Type C plug is connected to pin A2 in the terminal device 100.

Based on the structure shown in fig. 3, signals transmitted by the HDMI a interface are mainly divided into the following five types, except for the power signal transmitted by the pin C18 and the HPD signal transmitted by the pin C19:

the first signal is three pairs of TMDS data signals transmitted by pins C1-C9, plus three TMDS data mask signals (data mask).

The second signal is a pair of TMDS clock signals transmitted by pins C10 and C12, plus a TMDS clock mask signal (clock mask).

It is understood that the processor 110 may include the processor 110 disposed in a motherboard of the terminal device 100, such as a System On Chip (SOC) chip.

The control module 123 may input a first selection instruction to the first selector 121 and a second selection instruction to the second selector 122 according to a signal of the USB Type C header interface 124a. The first selector 121 inputs the corresponding first high-speed signal or second high-speed signal to the USB Type C female interface 124a through the high-speed signal output module according to the first selection instruction. The second selector 122 inputs the corresponding first low-speed signal or second low-speed signal to the USB Type C female interface 124a through the low-speed signal output module according to the second selection instruction.

As shown in fig. 5B, the external connection part 130 includes a USB Type C male interface 131a, a connection module 132, and a second male interface 133. The first end of the USB Type C male interface 131a is connected to the first end of the connection module 132, and the second end of the connection module 132 is connected to the first end of the second male interface 133. The USB Type C male interface 131a is configured to be connected to the USB Type C female interface 124a, and the second male interface 133 is configured to be connected to the external device 200. The second male interface 133 may be a male interface with other functions, such as an HDMI a male interface, and an RJ 45 male interface. And, pins A5 and B5 in USB Type C male interface 131a, i.e. two CC pins are connected to ground through two resistors, respectively. In fig. 5B, the HDMI a male interface or the RJ 45 male interface is not shown, and the two CC pins are not shown, and are connected to the ground through two resistors, respectively.

When the terminal device 100 is connected with the external device 200 through the USB Type C female interface 124a and the external connection component 130, the USB Type C female interface 124a is connected with the USB Type C male interface 131a, and the USB Type C male interface 131a transmits detection signals of the external device 200 detected by two CC pins, that is, two low-level signals, to the control module 123 through the USB Type C female interface 124 a. For example, if the second male interface 133 is an HDMI a male interface, the control module 123 confirms that the external device 200 is a device requiring the HDMI function according to the received two low level signals. Alternatively, if the second male interface 133 is an RJ 45 male interface, the control module 123 confirms that the external device 200 is a network connection device according to the received two low-level signals. It is understood that the algorithm for the control module 123 to confirm the type of the external device 200 according to the received two low level signals, or other signals, may be preset in the control module 123 or in the terminal device 100. In the embodiment of the present application, a preset algorithm for identifying the type of the external device is not particularly limited.

It can be appreciated that the method for determining the Type of the external device 200 connected to the second male interface 133 by using the signals of the two CC pins of the USB Type C male interface 131a may be preset in the control module 123. In the embodiment of the present application, the determination method set in the control module 123 and the type of the corresponding external device 200 are not specifically limited.

Therefore, the processor 110 may input a high-speed signal of a corresponding function to the USB Type C female interface 124a through the first selector 121, input a low-speed signal of a corresponding function to the USB Type C female interface 124a through the second selector 122, and perform signal transmission between the USB Type C female interface 124a and the external device 200. Such as for audio data/video signal transmission or for network signal transmission.

It will be appreciated that if the terminal device 100 is connected to other external devices corresponding to the USB Type-C interface function through the USB Type-C female interface 124a, the USB Type-C female interface 124a may transmit other types of external device detection signals, i.e., other level signals except for two low levels, to the control module 123. The control module 123 confirms that the external device 200 is other device requiring the USB Type C interface function signal according to the received signal. The processor 110 may input a high-speed signal corresponding to the USB Type C interface function to the USB Type C female interface 124a through the first selector 121, input a low-speed signal corresponding to the USB Type C interface function to the USB Type C female interface 124a through the second selector 122, and perform data transmission between the USB Type C female interface 124a and the external device 200.

When the terminal device 100 and the external connection part 130 are connected, signal transmission between the terminal device 100 and the external device 200 corresponding to the other interface function may be implemented only through the USB Type C interface. Such as a display screen for realizing the terminal device 100 and the function corresponding to the HDMI interface, or a network device for realizing the terminal device 100 and the function corresponding to the network interface, etc., without providing an interface of a larger size, such as an HDMI interface, a network interface, etc., on the terminal device 100.

The MUX1 chip is configured to select between CHANNEL1 and CHANNEL2, and output a signal output by the selected CHANNEL1 or a signal output by the CHANNEL2 to the USB Type C header interface 124a.

CHANNEL1 is used to transmit 8 high-speed signals between processor 110 and external devices corresponding to USB Type C interface functions, including high-speed TMDS signals transmitted by pins A2, A3, a10, a11, and B2, B3, B10, and B11 of the USB Type C interface. CHANNEL2 is used to transmit 8 high-speed signals between processor 110 and the external device corresponding to the HDMI a interface function, including TMDS data signals transmitted by data CHANNELs consisting of pins C1, C3, C4, C6, C7, and C9 of the HDMI a interface, and TMDS clock signals transmitted by pins C10 and C12.

The HDMI A interface is used for transmitting the pin quantity of high-speed signal, equals the pin quantity that USB Type C interface was used for transmitting high-speed signal. In one possible implementation, high speed signals of both interface types may be transmitted through pins A2, A3, a10, a11, B2, B3, B10, B11 in the USB Type C interface.

It can be appreciated that the signals transmitted by pins A6, A7, B6, B7 in the USB Type C interface and pins C15, C16, C19 of the HDMI a interface are all low speed signals. The HDMI A interface is used for transmitting the pin quantity of low-speed signals, and is smaller than the pin quantity of the USB Type C interface for transmitting high-speed signals. In one possible implementation, low speed signals of both interface types may be transmitted over pins A6, A7, B6, B7 in the USB Type C interface.

As shown in fig. 6B, 8 pins for transmitting high-speed signals in the USB Type C male interface 131a may be respectively connected to 8 pins of the HDMI a male interface 133a for transmitting high-speed signals, including a TX0 pin for connecting with a DATA0 pin, a TX1 pin for connecting with a DATA1 pin, a RX0 pin for connecting with a DATA2 pin, and a RX1 pin for connecting with a CLOCK pin. And, any 3 of 4 pins for transmitting low-speed signals in the USB Type C male interface 131a may be connected to 3 pins of the HDMI a male interface 133a for transmitting low-speed signals, respectively. For example, the SBU1 pin is connected with the SCL pin, the SBU2 pin is connected with the SDA pin, and the D+ pin is connected with the HPD pin.

If the second male interface 133 of the external connection part 130 is an HDMI a male interface, the control module 123 may recognize that the required interface function is an HDMI function according to the CC signal, and the control module 123 may transmit a first selection instruction to the MUX1 chip. The first selection instruction is used for selectively outputting a high-speed signal corresponding to the HDMI function, which is sent by the processor 110 in CHANNEL2, to the USB Type C header interface 124a through the MUX1 chip. The control module 123 may send a second selection instruction to the MUX2 chip. The second selection instruction is used for selectively outputting the low-speed signal corresponding to the HDMI function, which is sent by the processor 110 in CHANNEL4, to the USB Type C header interface 124a through the MUX2 chip.

The control module 123 may send a fourth selection instruction to the MUX2 chip, where the fourth selection instruction is used to selectively output, through the MUX2 chip, the low-speed signal corresponding to the USB function sent by the processor 110 in the CHANNEL4 to the USB Type C header interface 124a. The terminal device 100 and the external device 200 are enabled to perform signal transmission corresponding to the function of the USB interface, so as to realize the function corresponding to the USB interface.

According to the terminal equipment, when the external connection part is connected with the external equipment with the HDMI A female connector, and the terminal equipment is connected with the external connection part, the terminal equipment can only transmit signals corresponding to the HDMI interface function through the smaller USB Type C female connector. And when terminal equipment passes through USB Type C female head and connects other external equipment that corresponds to USB Type C interface function, can make the treater carry out the signal transmission that corresponds to USB Type C interface function with other external equipment again. The connector can reduce the number of interfaces of the terminal equipment and reduce the size and weight of the terminal equipment.
