Description

The key groups of portable electric device and use the keyboard of this key groups

Technical field

The utility model relates to a kind of keyboard, is specifically related to a kind of keyboard with key groups of portable electric device.

Background technology

Press-key structure (keyboard) all is a kind of indispensable input interface for various electronic installations, and the user imports various literal, numeral, symbol and carries out its function by this input interface, thereby allows the user can the described electronic installation of easy operation.

Employed press-key structure 10 on the operation interface on the traditional electronic devices as shown in Figure 1, is to arrange in the array mode.And on the keycap 102 of each button 101, be printed with the layout of patterns such as numeral, literal and symbol.When the user carried out short message editing on electronic installation, because short message editing has a plurality of territories, the employed writing language in each territory was all different.For example, when short message editing, object territory and information content edit field can appear sending in this short message editing.What send the required input in object territory is phone number, the user must switch to the input system of electronic installation under the pattern of numeral input, at this moment, when the user pushes button 101, the numeral that this button produced will be shown as numeral in sending the object territory.After numeral input, enter into information content edit field, the user needs system is switched under the pattern of literal input, and when the user pushes button after 101, this literal will be presented in the information content edit field.But when literal was imported, if when wanting inputting English letter " C ", the user must push on the button 101a more than three times or three times continuously, should just can be presented in the information content edit field by " C " English alphabet.If when wanting inputting English letter " Z ", the user must push on the button 101b more than four times or four times continuously, should just can be presented in the information content edit field by " Z " English alphabet.Thus, use the layout of literal on traditional button, numeral, symbol, can make the user when writing editor, very time-consuming, not easy to operate.

The utility model content

Therefore, the utility model fundamental purpose be to solve the defective of conventional keys, avoid it to lack and exist, after the utility model is with button layout again, allow the user write editor input characters, numeral, symbol can be easier.

For reaching above-mentioned purpose, the utility model provides a kind of key groups of portable electric device, described key groups is placed on the button housing, thereby provide the input of numeral/letter, it is characterized in that, described key groups comprises: main keycap for having circular outstanding housing, and is placed on the described button housing in the mode that can move up and down; The first side keycap in a side of described main keycap, and is placed on the described button housing in the mode that can move up and down; And the second side keycap at the relative opposite side of described main keycap, and is placed on the described button housing in the mode that can move up and down; Wherein, be printed with numeral and special symbol on the described main keycap, and described first side keycap and described second side keycap adjacent key-press shell surface be printed with literal and direction symbol.

By above-mentioned device, the utility model has been realized the layout again of button, allows the user when writing editor, more saves time, operates easily.

Embodiment

Below in conjunction with accompanying drawing the utility model is elaborated, yet accompanying drawing only is used to provide reference and explanation, is not to be used for limiting the utility model.

With reference to figure 2,3,4, they are respectively the part amplification of keyboard appearance of the present utility model, Fig. 2 and the synoptic diagram of analysing and observe at the 2-2 position of the 3rd figure section.As shown in the figure: the keyboard of portable electric device of the present utility model comprises: button housing 1, and a plurality ofly on button housing 1, arrange (preferably arranging) key groups (keyswitch set) 2 in the mode of 3 * 5 arrays in the array mode.Wherein, button housing 1 which is provided with a plurality of installing ports 11, and installing port 11 is used to dispose key groups 2, and makes the surface exposed of key groups 2.

Key groups 2 is made up of main keycap (keycap) 21, first side keycap 22 and second side keycap 23.Main keycap 21 is circular outstanding housing, and can be placed on the installing port 11 of button housing 1 in the mode that moves up and down, scribble on these main keycap 21 surfaces the numeral 211, the numeral 211 comprise the

numeral

1,2,3,4,5,6,7,8,9,0 and symbol *, # ,+,-, etc.For allow the user can be on electronic installation the signal of input digit 211.First side keycap 22, a side of the adjacent main keycap 21 in semicircular arc ground, and the mode that can move up and down is placed on the button housing 1.One side of first side keycap 22 bottoms is provided with protruding wall 221, and pulling on the interior sidewall surface of button housing 1 in protruding wall 221 tops, thereby prevents that first side keycap 22 from getting loose.In addition, button housing 1 lip-deep position in the adjacent side of first side keycap 22 and second side keycap 23 scribbles literal 12 and direction symbol, this literal 12 is English alphabet A～Z, is provided at the signal of electronic installation input characters 12 and direction operation thus for the user.Second side keycap 23, semicircular arc ground be adjacent to the opposite side of main keycap 21, and can be placed in the mode that moves up and down on the button housing 1.Side in second side keycap 23 bottoms has protruding wall 231, and pulling on the interior sidewall surface of button housing 1 in protruding wall 231 tops, gets loose to prevent second side keycap 23.In addition, for fear of user's false touch to main keycap 21, the area on first and

second side keycap

22,23 surfaces is less than the area on main keycap 21 surfaces, and the surface elevation of first side keycap 22 and dual side-edge keycap 23 is all a little more than this main keycap 21.

With reference to figure 5,6, they are respectively that key groups of the present utility model and signal produce the synoptic diagram of structure collocation use and the action synoptic diagram of Fig. 5.As shown in the figure: when key groups 2 of the present utility model in use, key groups 2 is positioned at signal and produces on the structure 3, signal produce structure 3 by configuration on circuit board 31 and the circuit board 31 with a plurality of shell fragments 32 that should key groups 2 are formed.

When the main keycap 21 of user's finger presses surperficial, this main keycap 21 produces downward action, allow main keycap 21 bottoms press in this pairing shell fragment 32a, shell fragment 32a is contacted with circuit board 31, thereby produce the signal of numeral 211, and transfer to the internal system (not shown) of electronic installation, on the display screen of electronic installation, can demonstrate the pattern of this numeral 211.

With reference to figure 7, this figure is another action synoptic diagram of Fig. 5.As shown in the figure: when user's finger presses in the surface of first side button cap 22 (or second side keycap 23), first side keycap 22 produces downward action.Keycap 22 bottoms in first side press pairing shell fragment 32b, shell fragment 32b is contacted with circuit board 31, thereby produce the signal of literal 12, and transfer to the internal system (not shown) of electronic installation, on the display screen of electronic installation, can demonstrate the pattern of this literal 12.

Further, the numeral 211 on main keycap 21 also can be imprinted on the surface of first side keycap 22 or second side keycap 23.And the literal 12 that is printed on button housing 1 surface also can be imprinted on the surface of main keycap 21, first side keycap 22 or second side keycap 23.

The above is a preferred embodiment of the present utility model only, is not therefore to limit claim of the present utility model, and every other equivalence of being done in the utility model characteristic range changes or modifies, and all should be included in the claim of the present utility model.
