Embodiment:
Below in conjunction with accompanying drawing the utility model is further described, sees Fig. 1～shown in Figure 6, this is preferred embodiment of the present utility model:
A kind of computer keyboard, it comprises body 1, described body 1 top is fixed with an auxiliary keyboard 2, described auxiliary keyboard 2 comprises main body 21, described main body 21 is provided with the modifier key 22 of self-defined key assignments, these main body 21 1 ends are provided with the connecting portion that is fixed in body 1 over top, and described main body 21 is provided with the USB interface that is electrically connected with described body 1.
Auxiliary keyboard 2 described in the utility model is fixed in body 1 over top finger by described connecting portion upholds palp position, and be electrically connected with body 1 by USB interface, preset the key assignments of each modifier key 22, in the use, each modifier key 22 of auxiliary keyboard 2 is used with the standard enter key of body 1, make under the not mobile situation of operator's palm, but the button of finger operating of contacts is many, so when carrying out the keyboard input operation, reduced the number of times that palm moves around, alleviate and use fatigue, and improved input speed, reduced the rate of inputing by mistake.
Wherein, described USB interface both can realize that data connected, and can realize conducting simultaneously, connected and stablized the data transmission credibility height.Described USB interface is the connecting interface that is widely used in electronic equipment, repeats no more its principle of work here.
See Fig. 2 and shown in Figure 4, described body 1 top is provided with slide rail 4, and the connecting portion of described auxiliary keyboard 2 comprises the web joint 23 that is articulated in main body 21 upper ends, and the free end of described web joint 23 offers the clip slot 231 that is complementary with described slide rail 4.Described clip slot 231 is held on described slide rail 4 peripheries, thereby make described auxiliary keyboard 2 be fixed in the correct position at described body 1 top, described main body 21 can be rotated around drive-connecting shaft, when need using described auxiliary keyboard 2, change main body 21 down around described drive-connecting shaft, make described modifier key 22 up, so that use; When not needing to use auxiliary keyboard 2, can rotate main body 21 around described drive-connecting shaft, make described main body 21 not block each button of body 1, this has improved the ease of use of auxiliary keyboard 2.
The connected mode of described clip slot 231 clamping slide rails 4 is dismountable fixedly connected mode,, when need using described auxiliary keyboard 2, can overlap the above clip slot 231 from described slide rail 4 one ends that is, makes clip slot 231 be held on described slide rail 4 peripheries; When need adjusting described auxiliary keyboard 2, can be along the described slide rail 4 described clip slot 231 that slides, thus make auxiliary keyboard 2 be positioned at the correct position on body 1 top; When not needing to use auxiliary keyboard 2, can deviate from described clip slot 231, thereby auxiliary keyboard 2 is broken away from and being connected of body 1 from slide rail 4 one ends.So described auxiliary keyboard 2 also can be bolt connection type, inlaid type or other dismountable mode of fixedlying connected with the connected mode of body 1, this does not influence result of use of the present utility model.
Wherein, described slide rail 4 surfaces are formed with limited block 41, and described clip slot 231 bottom land elasticity convex with fixing pin.Promote clip slot 231, when slide rail 4 slided described clip slot 231, described fixing pin clip slot 231 bottom lands of withdrawing under the effect of described limited block 41 were so that clip slot 231 can slide smoothly; After clip slot 231 slides into correct position, described fixing pin stretches out clip slot 231 bottom lands under the reseting elasticity effect, press on slide rail 4 surfaces, this fixing pin and described limited block 41 common constraint clip slots 231, clip slot 231 can not be free to slide along slide rail 4, this had both strengthened the be connected steadiness of auxiliary keyboard 2 with body 1, was convenient to mobile auxiliary keyboard 2 again, had improved ease of use and reliability.
See shown in Figure 3ly, be formed with the accommodation space 24 of ccontaining body 1 function key 19 between described main body 21 free ends and the described clip slot 231.Also that is to say, when described drive-connecting shaft changes down described main body 21, the free end lower edge of described main body 21 falls within the function key area and the neutral gear between the standard input keypad of body 1, thereby blocks the not high function key of frequency of utilization 19, and this makes input operation more convenient efficient.
Wherein, the back side of the described main body 21 auxiliary keyboard support that can be pivoted, during use, described auxiliary keyboard support can be produced and struts from main body 21 back sides, play the effect of supportive body 21, avoid main body 21 contacts to push the function key 19 that is contained in the described accommodation space 24, thereby avoided the mistake input, improved dependability of the present utility model.
