Abstract

The utility model discloses a mobile phone keyboard and a mobile phone with the keyboard. The keyboard comprises at least one idler wheel; the shaft of the idler wheel is fixed in the mobile phone; each idler wheel is evenly divided into a plurality of sectors according to the required number of number/sign input keys; each sector is corresponding to one input key and is provided with a contact point arranged on the shaft of the idler wheel for inputting signals to the mainboard of the mobile phone when the key is pressed down; and the mobile phone is a phone using the keyboard. Due to the delicate combination of the 360-degree rotating shaft and the idler wheel evenly divided into sectors, the mobile phone achieves the complete functions of number/sign keys in a single row, solves the conflict between the large screen and the small size, saves the mainboard space and also facilitates the using of customers.

Description

A kind of cell phone keyboard and use the mobile phone of this keyboard

Technical field:

The utility model relates to mobile phone, is specifically related to cell phone input keyboard.

Background technology:

Numbers and symbols key in the mobile phone overwhelming majority's who sells on the market the keyboard is three row four lines now, adopts three kinds of silica gel, P+R (plastics keycap, silica gel base plate), P+R+TPU (Thermoplastic polyurethane, thermoplastic polyurethane).Button on these keyboards requires keyboard glue shell and the gap between PCB (Printed CircuitBoard, the printed substrate) plate up and down to want 〉=0.8mm, and the height great majority of adding the whole button of keycap like this are more than 1.8mm.

If the function of mobile phone is more, then the number of keys except that numeral and symbolic key also increases accordingly on the keyboard.In order to make good hand touch, the area of keyboard is also moderate, thereby the function of mobile phone is many more, and the zone that keyboard accounts for is just big more, and correspondingly the volume of mobile phone is also just big more.

Along with the development of technology and the arrival in 3G epoch, the function of mobile phone is abundanter, and is bigger to the requirement of screen size, and under the constant situation of keyboard structure, big screen causes the size of complete machine to become big, and mobile phone will seem heavy can't bear.How solving the problem of dwindling the keyboard grabbing area, is the major issue that mobile phones design will be considered.

Be illustrated in figure 1 as the ordinary password lock construction, coded lock is made of several groups of rollers, and every group of roller is divided into 10 lattice, the corresponding password figure 0-9 of difference, and the area that the outside takies is less.This structure can be used on the cell phone keyboard, but does not see this technical scheme in the prior art.

The utility model content:

The technical problems to be solved in the utility model provides a kind of new cell phone keyboard, and the mobile phone that uses this keyboard is provided on this basis.It can solve the large-screen and the undersized contradiction of complete machine of mobile phone.

Cell phone keyboard in the utility model, comprise at least one roller, the axle of described roller is fixed in the mobile phone, each roller is divided into some sectors by the number of the numeral/symbol enter key of required setting on it, the corresponding enter key in each sector, there is a contact each sector on described roller shaft, when button is pressed to the cell phone mainboard input signal.

In above-mentioned cell phone keyboard, roller can be three, and each roller can the fourth class be divided into four sectors.With three rollers, and each roller fourth class is divided under the situation of four sectors, and 12 sectors correspond respectively to 10 numeric keys and " * ", " # " two symbolic keys.

In above-mentioned cell phone keyboard, can be with first roller as numeral/symbol " 1 ", " 4 ", " 7 ", " * " key, second roller is as numeral " 2 ", " 5 ", " 8 ", " 0 " key, the 3rd roller be as numeral/symbol " 3 ", " 6 ", " 9 ", " # " key.

There is geared system in described roller axle center in the above-mentioned cell phone keyboard, guarantees the clear switching between the sector when stirring roller.

Mobile phone in the utility model is to use the mobile phone of above-mentioned cell phone keyboard.

The utility model utilization can 360 angle rotating shaft and is divided into the ingenious combination of the roller of sector, realized single button realization numeral/symbol keys global function, solve the large-screen and the undersized contradiction of mobile phone, saved the mainboard space, also made things convenient for consumer's use simultaneously.

Fig. 1 is the coded lock structural representation of prior art;

Fig. 2 is the front view of an embodiment of the mobile phone in the utility model;

Fig. 3 is a kind of user mode figure of Fig. 2;

Fig. 4 is one group of button profile of Fig. 2.

Embodiment:

Fig. 2 is the front view of the mobile phone in the utility model.In the present embodiment, keyboard region has three rollers, each quartering.First roller corresponding key is numeral/symbol " 1 ", " 4 ", " 7 ", " * " key, transfer sequence are " 1 ", " 4 ", " 7 ", " * ", circulation is switched.Second roller corresponding key is numeral " 2 ", " 5 ", " 8 ", " 0 " key, transfer sequence are " 2 ", " 5 ", " 8 ", " 0 ", circulation is switched.The 3rd roller corresponding key is numeral/symbol " 3 ", " 6 ", " 9 ", " # " key, transfer sequence are " 3 ", " 6 ", " 9 ", " # ", circulation is switched.

Fig. 3 is a kind of user mode figure, pushed first roller at numerical key " 4 ", second roller at numerical key " 2 ", the 3rd roller state at symbolic key " # ".

Fig. 4 is the profile of first roller and corresponding button, and as can be seen from the figure, there is geared system in the roller axle center, the clear switching when this device is used for guaranteeing to stir roller between the sector.The contact when pushing button, is touched, to the cell phone mainboard input signal in corresponding contact below each button.
