Embodiment 1

[0043] Embodiment 1 (see figure 1 ) is a miniature external touch input keyboard for microcomputers and other equipment of the present invention, wherein the touch plate 1 that accepts touch pressure passes through the support plate 6, the connecting element 5 and a sensor with 12 sheet strain gauges. A beam-type aluminum elastic body 4, a supporting structure 3 connected to the elastic body and a housing 2 are supported; there are function keys on the housing; the touch panel 1 has 60 characters and squares marking each key area, and the sliding Touch the smooth surface for controlling the cursor or writing input; take the surface of the touch panel as a Cartesian coordinate system, and the strain gauges 15, 16, 17, and 18 laid on the elastic body 4 form a bridge that measures the moment of rotation with the Y axis as the axis of rotation. Circuit B ( Figure 5 ), strain gauges 19, 20, 21, 22 measure the bridge circuit C ( Figure 6 ), strain gauges 11, 12, 13, 14 form a br...

Embodiment 2

[0056] Embodiment 2 is also a kind of miniature external touch-press input keyboard used for equipment such as microcomputers, and its basic structure and working method are basically the same as Embodiment 1, except that the elastic body of the sensor used is L-beam-shaped (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 force-measuring bridge circuit A ( Figure 4 ), the strain gauges 15, 16, 17, 18 form a bridge circuit B ( Figure 5 ), the strain gauges 23, 24, 25, and 26 on the short arm of the beam bend form a bridge circuit D ( Figure 7 ).

Embodiment 3

[0057] Embodiment 3 is a wrist mobile phone that uses a greatly reduced input keyboard similar to Embodiment 1 that can choose two input modes, and the processor of its keyboard is the same processor as the mobile phone host; Size) when clicking input, when the touch force is 40-60 grams, the input is a phone number; when it is 10-25 grams, it is a part of the letters; When the touch pressure is different, the internal sounder will emit different tones of prompts. On its touch panel, you can use a pen or finger or even a thumb for writing input. At this time, the input will be the trajectory or stroke of the center of the thumb's 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 invention belongs to the information input technology for keyboards, handwriting input boards, microcomputers, hand-held telephones and other equipment. (two) background technology: [0002] Current information input devices are mainly keyboards, touch screens, etc. For portable or handheld or pocket-sized devices, these devices are too bulky. In order to avoid misuse, the width of each key or touch position should not be smaller than the end of the finger. Therefore, it is difficult to reduce the input device with more keys or touch positions. If the number of keys or touch positions is significantly reduced, the complexity of operation will be increased and the input speed will be reduced; there are also pocket input devices utilizing input pens, but Typing is slower and adds to the hassle of carrying the pen. [0003] In order to solve this difficulty, the applicant once proposed a solution (Chinese patents 03121386.3, 03153792.8), which i...
