Description
Technical field
The utility model relates to a kind of Multifunctional USB keyboard.
Background technology
The current social computer has become everyone the most basic instrument, is applied to all kinds of enterprises widely, and the work of complicated inconvenience in the past such as the message traffic of all such as, commercial intercourse, client's contact, word processing can be done by computer.Therefore the importance of computer also just displays thus especially.Along with the various old-fashioned interfaces of the development of computer all can't be expanded the extension use, development along with technology, increasing peripheral hardware needs interface, camera, digital camera, MP3 walkman, external hard disk, CD-ROM drive etc. are comed one after another, so is Duo equipment toward where connecing? the demand that enlarges day by day in the face of people, though old-fashioned external interface improves again and again, strengthens through people, can't continue really " old but vigorous ".Because demand and deficiency have caused contradiction, so a brand-new Peripheral Interface standard has been arisen at the historic moment.USB, Chinese full name are USB (universal serial bus) (Universal Serial Bus), and its interface only uses 4 lines altogether, and wherein two is power lead, and two is data line, are typical serial data transmission patterns.Wherein synchronous transfer module satisfied equipment requirements such as printer at a high speed, the data-transmission mode that continues, interrupt transmission mode and satisfied that similar mouse, the such wheel of keyboard look for an opportunity to make, the demand of low speed transmissions equipment, the blocks of data transmission then allows all kind of modulations demodulator device be given full play to.Except these top transmission modes, the USB standard also provides a brand-new technology---plug and play.The external interface that we use always can only and manually send the kind of information that detection signal obtains equipment on the interface by active often, even sometimes we also can't find.The type kind of COM port or COM device or COM1 detects and is difficult for; generally need manually to be provided with; the LPT mouth can not be installed or be removed under open state; may cause short circuit because LPT device plugs interface when hot line job, burn computer, PS/2 interface current amount is little; safeguard measure is appropriate; generally can not cause burning, but start the time plugs equipment and can not allow computer detect, can't use.Such situation has had a strong impact on the use of people to more and more peripheral hardwares, the plug and play technique that the USB standard provides effectively helps people to solve the ease of use problem, no matter when, as long as you want to use, you just can insert interface with equipment, finish using and just can pull up, improved the service efficiency of computer greatly.
Along with brand-new USB 2.0 standards are born, the transfer rate of USB device is up to 480Mbps, originally on USB 1.1, can use, but the equipment that suspicion speed is not enough also becomes alternative object, people not only can use mouse, the keyboard of USB interface, the scanner of USB interface, printer, more then be digital equipment and the movable storage device that becomes more and more popular.Though also have many people till now at the mouse, the keyboard that use PS/2, the printer of LPT mouth, the modulator-demodular unit of COM, but rely on the built-in power supply, high-speed transfer speed, and the huge convenience that brings to us of PnP plug and play technique, USB realizes that the external interface big unification is not a unpractical dream.
USB brings into use the history that surpasses 5 years till now, in these 5 years, the USB standard never has any change, but the application of USB is then in continuous increase, early stage people also just make simple mouse Peripheral Interface with it, have just occurred keyboard, printer, the scanner of USB interface subsequently.Along with formally coming into operation of USB 2.0, what all kinds of memory devices of USB interface developed allows the people too plenty for the eye to take it all in soon, not only Cheng Shu USB hard disk is accompanied by USB 2.0 those bandwidth one action breakthrough bottlenecks up to 480Mbps becomes the focus that people attract attention, and portable CD writer, flash memory disk storer are also accepted by people because of the raising of speed.The development of USB will can not stop, serial line interface has been confirmed as the direction of future development by people, following USB will move on along present cheapness and outstanding track, frequency is more and more higher, speed is more and more faster, and it is more and more convenient to use, and will become USB 3.0 and even 4.0 directions of making great efforts, perhaps in the near future, USB can expand to the present field that we can't imagine at all to its application.The application of USB will be a undisputable fact more and more widely, and people will be more and more obvious also for the dependence of USB.The normalized definition of USB can support 127 USB peripheral hardwares to be connected to computer system at most, physical arrangement is star-like, that is to say, even have only a USB interface on your mainboard, as long as you can find suitable usb hub (USB Hub), you just can realize connecting maximum 127 USB device.
Yet, people are when using all kinds of USB device, must bend over it is inserted on the main frame or by extra USBHUB or by other cables and be connected on the host computer, not only using and installing quite trouble inconvenience, and cause many connection cables to tangle in disorder difficult arrangement, a plurality of equipment connect the puzzlement that takies usage space, and when moving or dismantle host computer, many cables must be rearranged, more cause the inconvenience in the use; When a plurality of USB device are used simultaneously, must take a USB interface respectively, produce the not enough situation about using of USB interface, expand as need and use, then must expand use with USBHUB by the line that adds, increased trouble and use cost.
Summary of the invention
The purpose of this utility model provides a kind of Multifunctional USB keyboard that is convenient for people to use.
For achieving the above object, the utility model is taked following design proposal:
A kind of Multifunctional USB keyboard, comprise USB keyboard body, periphery at the USB keyboard is provided with three USB interface at least, usb hub is located at the inside of described keyboard, and connect keyboard circuit and USB interface in the keyboard respectively, by transmission control and usb data transmission kenel with the push button signalling of described keyboard circuit and all kinds of USB device signal storage to host computer.
The utility model has the advantages that:
1, reduce host computer peripheral device number of connection and take up room, promptly usb hub and the keyboard by brief introduction integrates, and can not take the number of cables of the peripheral device of a large amount of usage spaces and host computer.
2, usb hub and keyboard are integrated one, USB device is inserted more easily, need not bend over again to be inserted on the main frame, also need not increase other interconnecting devicies and connection cable.
3, usb hub and keyboard are integrated one, increased more USB interface, that avoids taking simultaneously a plurality of main frame USB interface additionally installs use additional, only finishes the use of a plurality of USB device by the USB interface of a main frame.
