Embodiment 1

[0142] 3( a ) is a schematic diagram of a peripheral device 300 connected to a terminal device 200 after being connected and installed and placed on a wireless charging pad for charging according to an embodiment of the present application. At this time, the device 100 is not connected to the peripheral device 300 .

[0143] It should be noted that, for the sake of brevity, the schematic diagram in Embodiment 1 refers to the VBUS pin and the DP / DN / SBU / TX / RX pin connected between the USB TYPE-C interface 310 and the USB TYPE-C interface 320. The feet have been omitted to varying degrees.

[0144] The peripheral device 300 is connected to the terminal device 200 through the USB TYPE-C interface 310 and the USB TYPE-C interface 210 .

[0145] It should be noted that the connection between the USB TYPE-C interface 210 and the USB TYPE-C interface 310 in the figure should be understood as the connection of the corresponding pins after the USB TYPE-C interface 310 is inserted into t...

Embodiment 2

[0200] Below with figure 2 Based on the circuit shown, a circuit-controlled state machine of a peripheral device 300 with a wireless charging function and a complete control program flow are introduced.

[0201] In the embodiment of the present application, the switching circuit 330 mainly has the following four working states, as shown in Table 1:

[0202] state Status Description switch on switch off 1 Power down state SW1, SW4 SW2, SW3, SW5, SW6 2 Connect the terminal device 200 SW2, SW3, SW5 SW1, SW4, SW6 3 Transparent device state SW1, SW4 SW2, SW3, SW5, SW6 4 Connecting the terminal device 200 and the device 100 SW2, SW3, SW5, SW6 SW1, SW4

[0203] Table 1

[0204] The switching of each state is shown in Fig. 6(a), the power-on and power-off of the switching circuit 330 determines the transition between state 1 and state 2, and the detection of the connection and disconnection of the charging device 100 determi...

Embodiment 3

[0253] Figure 7 A schematic circuit diagram of a possible docking station peripheral 300 is shown.

[0254] The peripheral device 300 includes a wireless charging module 340 and includes a plurality of peripheral devices 300 with USB TYPE-C interfaces.

[0255] Compared with the first embodiment, Figure 7 The peripheral device 300 in the device not only includes USB TYPE-C interface 310, USB TYPE-C interface 320, but also expands a number of USB TYPE-C interfaces, such as USB TYPE-C interface 311, USB TYPE-C interface 312, etc. In the peripheral device 300, according to the prior art, the DP / DN / SBU / TX / RX pins between the multiple USB TYPE-C interfaces 310, 320, 311, 312 can be connected and managed in the manner of a USB HUB ( The USB HUB management chip is omitted from the figure).

[0256] Similar to the first embodiment, when the peripheral device 300 is only connected to the terminal device 200 through the USB TYPE-C interface 310, the wireless module 340 of the perip...

Abstract

An embodiment of the present application provides a peripheral device, including: a first interface, a second interface, and a switching circuit; the peripheral device can establish a first connection with the first device through the first interface according to a preset protocol; if the second device is connected to When entering the second interface of the peripheral device: if the second device is a non-charging device, the peripheral device establishes a second connection with the second device according to the preset protocol, and sends an instruction to the first device through the first connection, so that the first device By communicating with the second device according to the preset protocol; if the second device is a charging device, disconnect the first connection established between the peripheral device and the first device, so that the first device and the second device follow the preset protocol. A third connection is established.

Description

technical field [0001] The embodiments of the present application relate to the field of communication technologies, and in particular, to a peripheral device. Background technique [0002] With the continuous development of human science and technology, terminal devices such as mobile phones, tablet computers, PDAs, and notebook computers have become more and more popular in people's daily life, and have become an indispensable part of people's lives. A peripheral device connected to a terminal device to enhance or expand the functionality of the terminal device. Taking the terminal device as a mobile phone as an example, a mobile phone case with a wireless charging function can be used as a peripheral device to provide additional wireless charging capability for the mobile phone. [0003] Figure 8(a) shows an existing mobile phone and a mobile phone case with wireless charging capability: [0004] The mobile phone case 500 can provide protection for the mobile phone 400;...
