As shown in fig. 1 to 3, the type-C power supply wire 100 of the present application includes a type-C male terminal 110 for connecting a host device 200 (e.g., a mobile phone), and a transmission line connected to the type-C male terminal 110. The transmission line is connected to the type-C male head 110 through a solder area 140 (see FIG. 3), the end of which is used to connect to a powered slave device 300 (e.g., a head mounted display device).
As shown in the design block diagram of fig. 3, in the present type-C power supply wire 100, a first switch Q1 is disposed between the power pin of the type-C male connector 110 and the transmission line (welding area 140). Moreover, this type-C power supply wire 100 further includes: a control chip 130 and a type-C female socket 120 for inserting a power adapter.
The control chip 130 is connected to the configuration channel CC1_ U of the type-C male connector 110 and the configuration channel CC1_ D of the transmission line, respectively, to implement positive and negative insertion detection, identify the current and voltage provided by the USB connection, and implement connection establishment and management between USB devices between data and the power source VBUS, and the control chip 130 may adopt a common CC logic chip.
the power pin of the type-C female socket 120 is connected to the transmission line (the soldering region 140) through the second switch Q2; the control chip 130 is also connected with the first switch, the second switch and the type-C female socket 120.
When the type-C female socket 120 is not plugged in the power adapter, the control chip 130 turns on the first switch Q1 and turns off the second switch Q2, so that the host device 200 supplies power through the transmission line; when the type-C female socket 120 is plugged with a power adapter, the control chip 130 turns off the first switch Q1 and turns on the second switch Q2, so that the power adapter supplies power through the transmission line.

When the type-C female socket 120 is plugged with a power adapter, the control chip 130 can also inform the host device 200 through the CC1_ U to stop supplying power, and turn on the third switch Q3, so that the power adapter can simultaneously supply power to the host device 200. This bidirectional power supply function of this type-C power supply wire rod 100 can further improve the duration of the host computer equipment 200, makes cell-phone etc. when as host computer equipment 200, even if the type-C interface is occupied still can charge. In addition, in practical applications, regardless of whether the third switch Q3 is provided, the control chip 130 may inform the host device 200 to stop supplying power through the CC1_ U when the power adapter is connected, so as to maintain the power supply protocol specification.
In the present embodiment, as shown in fig. 3, a distance sensing device 150 is disposed around the type-C female socket 120, and the control chip 130 is further connected to the distance sensing device 150. When the distance sensing device 150 detects that an object is approaching, the control chip 130 notifies the host apparatus 200 to supply power, turns off the second switch Q2 and the third switch Q3, and turns on the first switch Q1, so as to recover to the state that the host apparatus 200 supplies power to the slave apparatus 300 in advance, thereby avoiding power failure of the back-end slave apparatus 300 when the power adapter is suddenly unplugged.
Since the power supply main body of the type-C power supply wire 100 is changed, in use, if the power adapter is suddenly unplugged, the host device 200 may still need a short time interval (millisecond level) before supplying power to the slave device 300 again, which may cause the power failure of the slave device 300. Therefore, the distance sensing device 150 is arranged to detect the approach of an object to obtain the risk that the power adapter is pulled out, and the control chip 130 is triggered to switch the state, so that the host device 200 is restored to supply power to the slave device 300 in advance, and the power failure hidden trouble is eliminated.

In this embodiment, the first to third switches are MOS transistors. Of course, other devices with a switching function, such as a transistor, may also be used in the present application, and are not described herein.
In this embodiment, the type-C socket 120 supports a CC power supply protocol and a BC1.2 protocol, and the control chip 130 can detect whether a power adapter is inserted through the D + and D-pins of the type-C socket 120 according to the BC1.2 protocol. Of course, the type-C socket 120 can also inform the control chip 130 whether the power adapter is connected or not by using other protocols and other pins (such as CC pin).
in the present embodiment, as shown in fig. 3, the SUB1, SUB2, D +, D-, SSTX +, SSTX-, SSRX +, and SSRX-pins of the type-C male header 110 are directly connected to the transmission line (the soldering region 140) without passing through the control chip 130, i.e., the 8 communication pins are not affected by the control chip 130, so as to achieve through connection between the host device 200 and the slave device 300.

On the basis of the above state, if it is detected that the type-C female socket 120 has the power adapter inserted, the control chip 130 negotiates voltage and current with the power adapter, turns on Q2 after negotiation is completed, turns off Q1, supplies power to the head-mounted display device through the power adapter, negotiates with the mobile phone through CC1_ U, informs the mobile phone to stop supplying power, turns on Q2 and reversely charges the mobile phone, and accordingly, bidirectional power supply of the external power adapter is achieved.
in the above power adapter connection state, if it is detected that an object is close to the sensing area, it is considered that there is a risk of unplugging the power adapter, and after the control chip 130 detects the interrupt signal, it informs the mobile phone that the mobile phone needs to supply power through CC1_ U, and switches off Q3, turns on Q1, and switches off Q2, and switches back to the mobile phone power supply, so as to prevent the back-end device from being powered off due to the sudden unplugging of the power adapter.
