Keyboard module, portable electronic device having same and text input method

Abstract

The invention discloses a key module, which is provided with at least one key comprising a keycap, a key shaft part connected with the keycap and a plurality of spring pieces, wherein the key shaft part comprises a central shaft and a peripheral part formed by taking the central shaft as a center; the plurality of spring pieces are arranged on a circuit board in a way of corresponding to the central shaft and the end points of the peripheral part; and when the central shaft of the key shaft part or the end points of the peripheral part are stressed, the corresponding spring pieces trigger an electric contact of the circuit board. The invention also provides a portable electronic device having a keyboard module and a text input method using the portable electronic device. A user can complete text input by using the key module and the number of keys required is reduced greatly, so the size of the electronic device is reduced.

Description

technical field [0001] The invention relates to a keyboard module, in particular to a keyboard module with a novel structure, a portable electronic device with the keyboard module and a method for inputting characters by using the portable electronic device. Background technique [0002] With the rapid development of the communication industry, the use of various portable electronic devices such as mobile phones and personal digital assistants (PDAs) is becoming more and more popular. At the same time, more and more consumers are no longer satisfied with simple functions such as sending and receiving information and answering calls in portable electronic devices. Users hope that portable electronic devices can also have functions such as surfing the Internet and sending and receiving emails. To input text conveniently has become an important issue in the design of such portable electronic devices. [0003] In order to achieve the above functions, there are many PDAs or mobi...

Problems solved by technology

[0003] In order to achieve the above functions, there are many PDAs or mobile phones 10 (such as figure 1 ) using a QWERTY keyboard 12, in order to place the keys representing all English letters on one surface of the device, resulting in an increase in the overall width of the device

Therefore, this design cannot satisfy consumers' pursuit of short, small, light and thin portable electronic devices.

In addition, since the size of the portable electronic device itself is relatively small, and the keys of the English letters need to be arranged on it, the space between the keys will obviously be relatively compressed, so that the user will also make mistakes when inputting. When other keys are pressed
