Abstract

The utility model discloses digital equipment utilizing a USB (universal serial bus) 3.0 interface, which comprises a processor module supporting a USB2.0 and the USB3.0 interface. The USB3.0 interface is compatible with the USB2.0, a USB2.0 portion in the USB3.0 interface is still used as a USB2.0 interface, and pins which are added to the USB3.0 interface on the basis of the USB2.0 are used for transmitting other signals. The technical scheme adopts the USB3.0 which is frequently used in markets, and realizes transmission of USB2.0 signals and the other signals, such as audio and video signals, via the same interface at low cost. The digital equipment is compatible with a data wire of the USB2.0, can be charged and realize data transmission via the USB2.0 interface data wire, and is compatible with a mobile phone data wire when using a USB3.0 Micro interface.

Description

A kind of digital equipment that uses the USB3.0 interface

Technical field

The utility model relates to the digital equipment that is used for externally transmitting multiple signal.

Background technology

Along with science and technology and social progress, the popularizing of panel computer and intelligent mobile phone etc.As portable set, its maximum characteristics are exactly light succinct, and therefore, portable type electronic product is generally only joined one or two USB interface, and the interface of USB2.0 has only 5 pins.More existing digital equipments like panel computer, for exporting other signal, adopt the special purpose interface of 30 pins, with the PC exchanges data time, need the switching adapter; Simultaneously, cost is higher.Therefore, how on the basis of convenient and PC exchanges data,, draw like the VGA signal other signal with lower cost, exporting in the digital equipment of multiple signal in hope is a difficult problem.

The utility model content

To the problems referred to above, the utility model is intended to realize both adopting the data line of USB2.0 to carry out data transmission and charging through on the digital equipment of supporting USB2.0, using the USB3.0 interface; Can realize the transmission of other signal again with lower cost, like VGA, color difference components signal etc.

For realizing this technical purpose, the scheme of the utility model is: a kind of USB3. of use interface, the electronic system of support USB2.0.Comprise the processor module of supporting USB2.0 and the interface of USB3.0.The USB2.0 respective pin in the USB3.0 interface and the corresponding pin of processor module link to each other; Other signal output pin of all the other pins in the USB3.0 interface and processor module links to each other.

The beneficial effect of present technique scheme is: realize same interface transmission usb signal and other signal with lower cost.That main is USB3.0 interface compatibility USB2.0, can charge with the data line of USB2.0 and data transmission, need not extra patchcord, and convenient the use reduced cost, reduced the wasting of resources.

Embodiment

Below in conjunction with accompanying drawing and specific embodiment the utility model is explained further details.*

As shown in Figure 1, the signal wire of the utility model connects situation, comprises the processor module 1 of supporting USB2.0 and the interface of USB3.0.The USB2.0 respective pin 21 in the USB3.0 interface and the corresponding pin 11 of processor module link to each other; All the other pin twos 2 in the USB3.0 interface and other signal output pin 12 of processor module link to each other.

As shown in Figure 2; Because USB3.0 interface compatibility USB2.0; So can the plug 31 of USB2.0 data line be inserted the USB2.0 part 21 of USB3.0 interface, the USB interface 32 that data line is other is connected with other digital equipment, can carry out data transmission and charging; Join with the power supply of band USB interface, can charge.Using under the Micro USB situation compatible cellular phone data line.

As shown in Figure 3, when the data line of connecting band USB3.0 plug, data line USB3.0 plug 3 is inserted in the USB3.0 interface 2, can transmit USB2.0 part in other signal or the multiplex interface by the part pin, all pins all are used for transmitting other signal.

The above; Be merely the preferred embodiment of the utility model; Not in order to restriction the utility model, every technical spirit according to the utility model to any trickle modification that above embodiment did, be equal to replacement and improve, all should be included within the protection domain of the utility model technical scheme.

Claims

1. digital equipment that uses the USB3.0 interface comprises the processor module of supporting USB2.0 and the interface of USB3.0, and it is characterized in that: the USB2.0 respective pin in the USB3.0 interface and the corresponding pin of processor module link to each other; Other signal output pin of all the other pins in the USB3.0 interface and processor module links to each other.
