Abstract

The utility model relates to a keyboard capable of quickly switching between an uppercase input mode and a lowercase input mode. Keys are arranged on the top surface of a keyboard body, a keyboard circuit film is arranged on the lower portions of the keys, a carbon core is arranged at the contact position of each key and the keyboard circuit film, a sensor circuit film and multiple pressure sensors are arranged on the lower portion of the keyboard circuit film in sequence, and each pressure sensor corresponds to one key and connected with a keyboard microprocessor. The keyboard is simple in structure and convenient to operate and has good practical value, a user can switch between the uppercase input mode and the lowercase input mode conveniently by the aid of magnitude of key pressing force, and requirement on quick switching between the uppercase input mode and the lowercase input mode is met.

Description

Can switch fast the keyboard of capital and small letter
Technical field
The utility model relates to a kind of keyboard, especially a kind of keyboard that can switch fast capital and small letter.
Background technology
At present, when people use keyboard input capital and small letter, all must carry out the capital and small letter blocked operation, and often misoperation, switch not fast, bring very large inconvenience to the user, solution is not preferably also arranged so far.
The utility model content
In keyboard operation, capital and small letter switches the problem of inconvenience in order to solve, the utility model proposes a kind of keyboard that can switch fast capital and small letter, this keyboard structure is simple, easy and simple to handle, the user can be conveniently carries out capital and small letter and switches by the button size of exerting oneself, satisfy the demand of switching fast capital and small letter, have practical value preferably.
The technical scheme that its technical matters that solves the utility model adopts is: the keyboard that this can switch capital and small letter fast, comprise keyboard body, and the end face of described keyboard body is provided with button, and the button bottom is the keyboard circuit film; The position that each button contacts with the keyboard circuit film is provided with a carbon heart; The bottom of described keyboard circuit film is sequentially with sensor circuit film and pressure transducer, and described pressure transducer is a plurality of, the corresponding button of each pressure transducer, and described pressure transducer is connected with keyboard microprocessor.
The beneficial effects of the utility model are: this keyboard structure that can switch fast capital and small letter is simple, easy and simple to handle, the user can be conveniently carries out capital and small letter and switches by the button size of exerting oneself, and satisfies the demand of switching fast capital and small letter, has practical value preferably.
Description of drawings
The utility model is described in further detail below in conjunction with drawings and Examples.
Accompanying drawing 1 can switch the one-piece construction schematic diagram of the keyboard of capital and small letter fast for this.
Accompanying drawing 2 can switch the keyboard monomer vertical section structure schematic diagram of capital and small letter fast for this.
In figure, 1. keyboard body, 2. button, 3. the carbon heart, 4. keyboard circuit film, 5. sensor circuit film, 6. pressure transducer, 7. keyboard microprocessor.
Embodiment
In the accompanying drawings, the keyboard that this can switch capital and small letter fast comprises keyboard body 1, and the end face of described keyboard body 1 is provided with button 2, and button 2 bottoms are keyboard circuit film 4; Each button 2 contacts 4 position and is provided with a carbon heart 3 with the keyboard circuit film; The bottom of described keyboard circuit film 4 is sequentially with sensor circuit film 5 and pressure transducer 6, and described pressure transducer 6 is a plurality of, the corresponding button 2 of each pressure transducer 6, and described pressure transducer 6 is connected with keyboard microprocessor 7.
Button 2 is in case pressed, and the ranks dot matrix signal at this key place just thinks and connect, and keyboard will send position encoded by the ranks dot matrix at button 2 places to main frame; The pressure sensitivity of pressure transducer 6 can be regulated voluntarily, corresponding to each button 2, there is a miniature pressure transducer 6 corresponding with it, 2 pressure surpasses certain value if push button, pressure transducer 6 will send a high level to keyboard microprocessor 7, if button 2 pressure are less, what send is a low level, carries out capital and small letter with different dynamics and switches.Keyboard microprocessor 7 inside judge by the mode of software, if what receive from pressure transducer 6 is high level, can trigger capitalization, and the input capitalization is to display; If what receive is low level, output is lowercase, has so just facilitated capital and small letter to switch.
