Description
technical field:
The utility model belongs to art of keypads, particularly relates to a kind of Multi-Function Keyboard.
background technology:
Along with the development of science and technology, current USB interface has been widely used in the advantage such as computer realm, fast, the timely plug of its transmission speed also makes it more and more important.But USB interface is arranged on host computer rear panel or below front panel mostly, therefore when user needs to connect USB device (as flash disk, portable hard drive, mobile phone), need removable computer main frame or USB device described in grafting to computer desk of bending over, this causes inconvenience to user to a certain extent.On existing keyboard, function is fairly simple in addition, only has the function of input characters, symbol and numeral.The switching on and shutting down of computer all need at the enterprising line operate of host computer, and the interface of audio frequency apparatus is all generally be arranged on main frame, and grafting is very inconvenient.
Existing Computer key generally adopts shearing supporting construction, and the space that this structure needs operation stability that is comparatively large and button is poor, and user uses very inconvenient.
utility model content:
The utility model overcomes the deficiency that prior art exists, solve prior art Problems existing, aim to provide a kind of structure simple, easy to use, keyboard is set up USB interface, host switch switch and audio frequency interface and the stable Multi-Function Keyboard of host switch machine button.
For solving the problems of the technologies described above, the technical solution adopted in the utility model is: Multi-Function Keyboard, comprise keyboard fixed frame, described keyboard fixed frame internal fixtion is provided with keyboard control circuit plate, described keyboard control circuit plate is electrically connected with card reader module and audio-frequency module, described card reader module is electrically connected with at least one usb expansion interface, described keyboard control circuit plate is provided with host switch machine control circuit, and dynamo-electric road is provided with host switch machine button to described host switch.
Further, the side, rear end of described keyboard fixed frame is provided with audio-frequency module mounting hole and at least one usb expansion interface mounting hole, the middle part of keyboard fixed frame front panel is provided with host switch machine button mounting hole.
Further, described keyboard also comprises the card reader indicating device be connected with described card reader module, described card reader indicating device is arranged at the right side of keyboard fixed frame front panel, for showing the duty of the extraneous USB device be connected with card reader module by described usb expansion interface.
Further, described card reader indicating device is status indicator lamp.
Further, the quantity of described usb expansion interface is two.
Further, host switch machine button comprises keycap, the first elastic component, the second elastic component and the 3rd elastic component, keycap is arranged in host switch machine button mounting hole, one end of first elastic component is connected to the first side of keycap, and the other end is connected to host switch machine button mounting hole, one end of second elastic component is connected to the second side of keycap, and the other end is connected to host switch machine button mounting hole, and the 3rd elastic component is arranged between keycap and keyboard control circuit plate.
Further, described 3rd elastic component is rubber washer or metal spring leaf.
The utility model compared with prior art has following beneficial effect: the utility model by arranging usb expansion interface on keyboard fixed frame, can grafting digital equipment quickly and easily, the USB on host computer can also be saved, do not need at an extra link extended line to desktop.Keyboard arranges host switch machine button, can direct control host switch machine on keyboard again, do not need user to bend over to operate on host computer, easy to use.Audio-frequency module and audio-frequency module mounting hole are set in addition on keyboard, so just can grafting audio frequency apparatus on keyboard again, be not linked on host computer at needs.
accompanying drawing illustrates:
Below in conjunction with accompanying drawing, the utility model is described in more detail
Fig. 1 is the plan structure schematic diagram of the utility model Multi-Function Keyboard
Fig. 2 is the structural representation of Multi-Function Keyboard side
Fig. 3 is the structural representation at the Multi-Function Keyboard back side
Fig. 4 is the structural representation of host switch machine button.
In figure: 1 is keyboard fixed frame, 2 is usb expansion interface mounting hole, and 3 is audio-frequency module mounting hole, and 4 is host switch machine button, 41 is keycap, and 42 is the first elastic component, and 43 is the second elastic component, 44 is host switch machine button mounting hole, and 45 is the 3rd elastic component, and 5 is card reader indicating device.
embodiment:
As shown in Figure 1-Figure 3, Multi-Function Keyboard, comprise keyboard fixed frame 1, described keyboard fixed frame 1 internal fixtion is provided with keyboard control circuit plate, described keyboard control circuit plate is electrically connected with card reader module and audio-frequency module, described card reader module is electrically connected with at least one usb expansion interface, described keyboard control circuit plate is provided with host switch machine control circuit, and dynamo-electric road is provided with host switch machine button 4 to described host switch.
In order to install fixing usb expansion interface, audio-frequency module and host switch machine button 4 better, the side, rear end of described keyboard fixed frame 1 is provided with audio-frequency module mounting hole 3 and at least one usb expansion interface mounting hole 2, the middle part of keyboard fixed frame 1 front panel is provided with host switch machine button mounting hole 44.
