Abstract
The utility model provides a portable wireless keyboard, which comprises a hand-held keyboard (1) and a bluetooth wireless receiver (2), wherein the hand-held keyboard (1) provides keyboard input and touch panel input, and the bluetooth wireless receiver (2) is connected with the hand-held keyboard (1) in a wireless communication way through the bluetooth 2.0 wireless technology, and is connected with a computer mainframe through a universal serial bus (USB) interface. The portable wireless keyboard has the advantages of simple structure, portability and rich function and is convenient to use.
Description
Technical field
The utility model relates to a kind of keyboard, especially relates to a kind of Wireless Keyboard that is provided with the portable multifunctional of touch-screen input and button input.
Background technology
Normally need by suitable transport interface between tradition computer and each peripherals, and interconnect with signal wire and to carry out conversion of signals and information transmission.But, because of signal wire between each peripherals and host computer, each peripherals will unavoidably can be subjected to the signal wire influence, and range of movement, handwriting pad and the keyboard that has for example limited mouse can not surmount conductor length in addition etc., thereby cause the inconvenience and the puzzlement of operation.
Though Wireless Keyboard and wireless mouse are just admitted by increasing consumer.But Wireless Keyboard remains two different external device (ED)s with wireless mouse, still need to take placing space respectively, and mouse also needs a bigger sliding space.Yet, general family or office put on the desktop of computer, usually also be placed with other peripheral equipment (as: printer, scanner etc.) or other office appliances etc., the space that can put on the desktop is diminished, and then the position that mouse is put is restricted and cause to use and go up inconvenience.
The utility model content
Present keyboard, mouse volume are big in order to overcome, the shortcoming of function singleness, and the utility model provides a kind of portable Wireless Keyboard, has advantage simple in structure, easy to carry, easy to use, feature richness.
The utility model has adopted following technical scheme to realize: a kind of portable mobile wireless keyboard, and it comprises: the handheld keyboard that keyboard input and touch pad input are provided; With the blue teeth wireless receiver that handheld keyboard is connected with communication by bluetooth 2.0 wireless technologys, this blue teeth wireless receiver connects host computer by USB interface.
Wherein, this handheld keyboard comprises: power circuit; The keyboard and the keyboard matrix circuit of keyboard input information are provided, and it connects blue teeth wireless emission control module; The touch pad and the touch control circuit of touch pad input information are provided, and it connects second microcontroller and this second microcontroller passes through I
2The C bus interface connects blue teeth wireless emission control module.
Wherein, handheld keyboard also comprises: the laser lamp that connects power circuit is or/and the LED lamp.
Wherein, handheld keyboard also comprises: the keyboard pilot lamp that connects first microcontroller.
Keyboard input that the utility model is integrated and touch pad input, and the employing wireless mode reaches host computer with input information, thus the restriction of wired keyboard and wire mouse eliminated to environment for use; In addition, portable mobile wireless keyboard of the present utility model also is provided with laser lamp or LED lamp, and Wireless Keyboard can be used in conjunction with projector, is convenient to use in occasions such as electronic teaching, speech, academic conferences.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is the structural representation of handheld keyboard among Fig. 1.
Embodiment
As shown in Figure 1, the portable mobile wireless keyboard of the utility model exposure comprises: handheld keyboard 1 and blue teeth wireless receiver 2.The information that handheld keyboard 1 sends sends blue teeth wireless receiver 2 to by bluetooth 2.0 wireless communication techniques, sends host computer by blue teeth wireless receiver 2 to by USB interface, to realize that the portable mobile wireless keyboard is to the button that calculates and the input of mouse message.
Wherein, this blue teeth wireless receiver 2 is blue teeth wireless receivers that blue teeth wireless reception module or computing machine carry.Be connected with a usb circuit 3 between blue teeth wireless receiver 2 and host computer, this usb circuit 3 links to each other with outside host computer by USB interface.Like this, blue teeth wireless receiver 2 will become USB interface information to send host computer to by usb circuit 3 from the information translation of handheld keyboard 1.
In conjunction with shown in Figure 2, this handheld keyboard 1 comprises: by the keyboard and the keyboard matrix circuit 11 of blue teeth wireless emission control module 12 controls; By the touch pad and the touch control circuit 13 of 14 controls of second microcontroller, this second microcontroller 14 passes through I
2The C bus interface becomes wireless signal to send to blue teeth wireless receiver 2 by bluetooth 2.0 wireless communication techniques information translation with this blue teeth wireless emission control module 12 of blue teeth wireless emission control module 12 communications; The power circuit 16 that constitutes by battery and charging circuit thereof, LDO power supply changeover device, and by the laser lamp 19 of power circuit 16 power supplies and the LED lamp 18 of high brightness; And the keyboard pilot lamp 17 that connects first microcontroller 12.
In addition, touch pad is a capacitive type touch pad, and corresponding touch pad control circuit is the capacitance touch sensor circuit, by the action of 14 scannings of second microcontroller and parsing appearance formula touch pad; And second microcontroller 14 passes through I
2The C bus interface sends to blue teeth wireless emission control module 12 with the touch pad control information.
And the laser lamp of installing on the portable handheld keyboard 1 19 can use handheld keyboard 1 in conjunction with projector, is convenient to use in occasions such as electronic teaching, speech, academic conferences; The LED lamp 18 of the high brightness of installing on the handheld keyboard 1 in the darker occasion of light, or is in when appreciating video display, can substitute electric torch and use as temporary lighting.
