Problems solved by technology

[0002] At present, the input keyboards of mobile phones generally include two types. One is a mechanical keyboard. Two-stage feel, but the disadvantage is that the keyboard surface cannot realize handwriting and touch input
The other is a touch panel keyboard, as shown in Figure 2, which is mainly connected by a capacitive/resistive touch sensor to the PCB through a connector. Use a pen or finger to touch the sensor, detect the position of the point through the circuit, and use a special The software implements function input, but the disadvantage is that it lacks the two-stage feel of pressing the button, and because there is no feeling of pressing, sometimes it is not clear whether to press the button, resulting in repeated buttons, which is not conducive to the use of nearsighted or blind users.
[0003] In addition, in the Chinese utility model patent announcement number CN2565217Y, the announcement date was August 6, 2003, and the name is "upright mo

Embodiment Construction

[0034] As shown in FIG. 3 , it is an exploded schematic diagram of the input keyboard structure of the present invention. It includes a touch panel 1 , a touch sensor 2 , a button bracket 3 , a metal shrapnel layer 4 , and a circuit board (PCB) 5 from top to bottom. Among them, the tablet key 1 and the touch sensor 2 form a touch panel input keyboard, and the key bracket 3, the metal shrapnel layer 4 and the circuit board 5 form a mechanical key structure.

[0035] As shown in Fig. 4, it is a cross-sectional view of the structure of the input keyboard of the present invention. First, when the user touches the touchpad 1 with a pen or finger, the point is sensed by the circuit on the touch sensor 2, and the function input is realized by using professional software. Secondly, the touch panel 1 can also be pressed down, through the elastic deformation of the button bracket 3, especially the metal shrapnel 6 of the metal shrapnel layer 4 is deformed by the contact 10 on the rever...

Abstract

This invention discloses one touch module key structure and its method for cell phone handle digital codes, wherein, Touch board key structure is imbedded with mechanic keys in touch key to realize dial photon function; the key is realized through spring metal spring; due to the metal slice its dial has key sense. This invention can realize above function operation and determination function based on above hardware metal spring.

Description

technical field [0001] The invention relates to a key structure of a touch panel, and also relates to a method for respectively realizing dialing, navigation, mouse operation and multimedia browsing by using the key structure, which is suitable for hand-held digital products such as mobile phones. Background technique [0002] At present, the input keyboards of mobile phones generally include two types. One is a mechanical keyboard. Two-stage feel, but the disadvantage is that the keyboard surface cannot realize handwriting and touch input. The other is a touch panel keyboard, as shown in Figure 2, which is mainly connected by a capacitive / resistive touch sensor to the PCB through a connector. Use a pen or finger to touch the sensor, detect the position of the point through the circuit, and use a special The software implements function input, but the disadvantage is that it lacks the two-stage feel of pressing the button, and because there is no pressing feel, sometimes it...
