Embodiment 1

[0142] FIG. 3( a ) is a schematic diagram of a peripheral device 300 connected to a terminal device 200 according to an embodiment of the present application and placed on a wireless charging pad for charging. 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 the first embodiment is for 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 are 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 between the corresponding pins after the USB TYPE-C interface 310 is inserted into the USB TYPE-C interface 210....

Embodiment 2

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

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

[0202]

[0203] Table 1

[0204] The switching of each state is shown in Figure 6(a). The power-on and power-off of the transfer circuit 330 determines the transition between state 1 and state 2, and the detection of the connection and disconnection of the charging device 100 determines the transition between state 1 and state 2. In the transition of state 2 and state 3 , detecting the connection and disconnection of the non-charging device 100 determines the transition in state 2 and state 4 . Wherein, the switch state of state 1 is the same as that of state 3.

[0205] Combine below Figure 6(a) and 6(b) Introduce the speci...

Embodiment 3

[0253] Figure 7 A schematic circuit diagram of a possible docking station type peripheral device 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 Example 1, Figure 7 The peripheral device 300 in the device not only includes a USB TYPE-C interface 310 and a USB TYPE-C interface 320, but also expands a plurality of USB TYPE-C interfaces, such as a USB TYPE-C interface 311, a USB TYPE-C interface 312, etc. In the peripheral device 300, according to the prior art, the DP / DN / SBU / TX / RX pins between multiple USB TYPE-C interfaces 310, 320, 311, 312 can be connected and managed in the manner of USB HUB ( The USB HUB management chip is omitted in the figure).

[0256] Similar to Embodiment 1, 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 periph...

Abstract

The embodiment of the invention provides peripheral equipment. The peripheral equipment comprises a first interface, a second interface and a switching circuit, the peripheral equipment can establisha first connection with a first device through the first interface according to a preset protocol; if a second device accesses the second interface of the peripheral equipment, if the second device isa non-charging device, the peripheral equipment establishes a second connection with the second device according to a preset protocol, and sends an instruction to the first device through the first connection, so that the first device communicates with the second device according to the preset protocol, and if the second device is a charging device, the first connection established between the peripheral device and the first device is disconnected, so that the first device and the second device establish a third connection according to a preset protocol.

Description

technical field [0001] The embodiments of the present application relate to the technical field of communications, 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, handheld computers, 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 and used to enhance or expand the function 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 capabilities 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...
