Embodiment 1

[0047] Example 1 (see figure 1 ) Is a miniature external touch input keyboard for microcomputers and other devices of the present invention, in which the touch pressure plate 1 that receives the touch pressure passes through the pallet 6, the connecting element 5, and a sensor with 12 sheet strain gauges. A beam-type aluminum elastic body 4, a supporting structure 3 connecting the elastic body, and a housing 2 are supported; there are function keys on the housing; the touch plate 1 has 60 characters and squares marking each key area and sliding Touch pressure controls the cursor or the smooth area of ​​writing input; taking the surface of the touch pressure plate as the rectangular coordinate system, the strain gauges 15, 16, 17, 18 laid on the elastic body 4 constitute a bridge type that measures the moment with the Y axis as the rotation axis Circuit B ( Figure 5 ), the bridge circuit C( Figure 6 ), strain gauges 11, 12, 13, 14 form a bridge circuit A ( Figure 4 ); The botto...

Embodiment 2

[0064] Embodiment 2 is also a miniature external touch input keyboard used for microcomputers and other devices. The basic structure and working mode are basically the same as those of Embodiment 1, except that the sensor elastic body used is an L-beam (see image 3 ), there are connecting screw holes 10 for connecting the support structure 3 and the connecting element 2 at both ends, and the sheet strain gauges 11, 12, 13, 14 laid on the elastic body form a bridge circuit A ( Figure 4 ), strain gauges 15, 16, 17, 18 form a bridge circuit B ( Figure 5 ), the strain gauges 23, 24, 25, 26 located on the short arm of the beam bending form a bridge circuit D ( Figure 7 ).

Embodiment 3

[0065] Example 3 is a wrist phone with a greatly reduced input keyboard similar to that of Example 1. The keyboard processor and the phone host are the same processor; on its touch pad (about a stamp Size) When you click to enter, when the touch pressure is 40-60 grams, you enter a phone number; when it is 10-25 grams, you enter a part of letters; when it is 25-40 grams, you enter another part of letters. When the contact pressure is different, the internal sounder will emit different tones of beeps. On its touch pad, you can use a pen or finger or even your thumb to write and input. At this time, the input will be the track or stroke of the center of the thumb touch pressure.

Abstract

The invention relates to an information input device and method with pressing board that includes pressing board, force sensitive sensor, and casing. The whole support the pressing board gained would pass through a sensor elastic body. On the elastic body or the elastic body group and carrying the strain gauge, the pressed location would be calculated and judged according to the moment and torsion moment. The device and method simplifies the structure of the device and obviously improves the working accuracy, stability and reliability.

Description

(1) Technical field: [0001] The present invention belongs to the information input technology used for keyboards, handwriting input boards, microcomputers, handheld phones and other equipment. (2) Background technology: [0002] The current information input devices are mainly keyboards, touch screens, etc. For portable or handheld or pocket-sized devices, these devices are too bulky. To avoid misoperation, the width of each button or touch position should not be smaller than the end of the finger Therefore, input devices with more buttons or touch positions are difficult to shrink. If the number of buttons or touch positions is significantly reduced, it will increase the complexity of the operation and reduce the input speed. There are also pocket input devices that use input pens, but The input is slower and it also increases the trouble of carrying the pen. [0003] In order to solve this difficulty, the applicant has proposed a solution (Chinese patents 03121386.3, 03153792.8...
