Description

A kind of press-key structure of communication electronic device

Technical field

The utility model is meant a kind of press-key structure that is used for communication electronic device especially relevant for a kind of press-key structure.

Background technology

Technology prosperity now, communication electronic device as mobile phone or PDA, except the function with conversation, can also connect the Internet, and photography diversified function such as take pictures.Therefore, present communication electronic device is used by society at large.

In order to make the communication electronic device can input characters, communication electronic device can be installed a plurality of buttons mostly, makes the user can operate communication electronic device by a plurality of buttons.The part communication electronic device, for example PDA can adopt and the general similar QWERTY keyboard (Qwerty Key) of computor-keyboard mostly.And QWERTY keyboard is because have the advantage of the corresponding character of a button, so the character input is very fast, an English alphabet, a numeral or a character such as phonetic symbol will occur by a key.

Yet the number of keys of QWERTY keyboard numerous (surpassing 26 buttons at least) causes the volume that must strengthen communication electronic device, just can hold numerous button.Like this, cause communication electronic device to dwindle, and the advantage of forfeiture carrying convenience.For this reason, some communication electronic device dwindles button, to dwindle the volume of communication electronic device.Yet the number of keys of QWERTY keyboard is numerous, and also causing needs the more time assembling of cost.

In order to solve the aforesaid drawbacks, see also Fig. 1, be the button 110 of known communication electronic installation 100 now.Communication electronic device 100 comprises a plurality of buttons 110.Utilize the number of times of pressing keys 110, make each button 110 can import a plurality of characters.So, can dwindle the volume of communication electronic device 100, and the advantage of carrying convenience is arranged.In addition, because reduce the number of button 110, therefore have more the advantage of the time that reduces the assembling button.

In addition, at present known technology more with two buttons 110 or the button of two QWERTY keyboard synthesizes a button.Like this, more reduce number of keys, more can shorten the effect of built-up time.Yet,, sacrificed the button sense of touch though two buttons, 110 synthetic buttons can be shortened built-up time.

For this reason, the utility model discloses a kind of press-key structure, can be with two by being bonded to a button, simplifying the assembling mode of button, and the volume that dwindles communication electronic device.In addition, more can possess the button sense of touch, make the convenient use of user.

Summary of the invention

The purpose of this utility model is to provide a kind of press-key structure of communication electronic device, when make using button of the present utility model, has preferable button sense of touch.

Another purpose of the utility model is to provide a kind of press-key structure of communication electronic device, with the assembling mode of simplifying button and the volume that dwindles communication electronic device.

For reaching the above object, the press-key structure of the communication electronic device that the utility model discloses, the surface of its button has at least two ridges, and therefore button of the present utility model has the advantage of preferable button sense of touch.

For reaching the above object, the press-key structure of the communication electronic device that the utility model discloses is applicable to a communication electronic device.Communication electronic device comprises a shell, and shell has a plurality of holes, and those buttons are in those holes.Button has a upper surface and a lower surface, and comprises two ridges, all is disposed at upper surface, in order to press button.

For making advantage of the present utility model and the spirit can be further revealed, now conjunction with figs. do one describe in detail as after.

Description of drawings

Fig. 1 is known button schematic diagram.

Fig. 2 is a schematic diagram of the present utility model.

Fig. 3 is an internal structure schematic diagram of the present utility model.

Embodiment

Below disclose advantage of the present utility model and spirit.

See also Fig. 2, be press-key structure of the present utility model.Shown in the figure, communication electronic device 300 comprises shell 320 and a plurality of button 310.Shell 320 has a plurality of holes (not indicating among the figure).Each hole is separated by moulding 321.

Button 310 has a upper surface and a lower surface, and it comprises two ridges, 311, two ridges 311 in above-mentioned hole.

Two ridges 311 all are disposed at the upper surface of button 310, press button in order to provide.And moulding 321 is between two ridges 311.

Structure about button 310 of the present utility model has numerous embodiments.Wherein preferable a kind of execution mode, as shown in Figure 3.The inside of button 310 comprises fixed iron piece 402, fixed axis 404 and

spring

406 and 408.

Fixed axis 404 is disposed at the lower surface of button 310.The position of fixed axis 404 is between two ridges 311.With fixed axis 404 is fulcrum, when button is subjected to pushing, can tilt to the left or to the right.Therefore, make button of the present utility model have the seesaw structure.

This fixed iron piece 402 has a plurality of perforation 414,416 and 412, and bores a hole 412 for doing to run through for fixed axis 404, to combine with button 310.In addition, utilize fixed axis 104 to make a fulcrum, make button 310 when being subjected to pushing, as seesaw, can tilt to the left or to the right, and, carry out the action of circuit triggers through the trigger switch (not shown) on the 312 pairs of communication electronic devices 300 of trigger column on the button 310, wanted the function that produces with the generation user.

Spring

406 and 408 is inserted in respectively on each trigger column 312.

Spring

406 and 408 is in order to provide elastic force, is returned to original position after button 310 is pushed.

Above-mentioned button 310 internal structures only are one of most embodiment of the utility model.Emphasize that at this above-mentioned preferred embodiment is not in order to limit feature of the present utility model.Secondly, button 310 can not only have two ridges, also can be three, or four, for example the quadrangle button.In addition, though ridge 311 is dome structures, can certainly be other shapes, for example can adopt cube or cylinder.By the above, button of the present utility model has the advantage of preferable button sense of touch and preferable button visual effect.

The above is to utilize a preferred embodiment and different embodiment to describe the utility model in detail, it is not in order to limit practical range of the present invention, and be familiar with present technique field person and all can understand, the modification of suitably making does not slightly still break away from spirit of the present utility model and scope.
