Embodiment 1

[0047] Embodiment 1 (Fig. 1) is a kind of miniature external keyboard of the present technology, and its 30 keys are keys, carried by 1 carrier, there are 4 stress sensors between the structure base plate and the carrier bottom (can be similar In addition to Honeywell's standard touch force sensor), the click force of any button can be transmitted to these 4 sensors. The signal processing circuit and processor inside the keyboard (omitted and not shown in accompanying drawing 1) can sum the force signals of these 4 sensors at any time (resultant force signal value), and calculate when a certain key is pressed. The instantaneous maximum value of the resultant force signal during a single click and the difference between it and the resultant force signal value when no button is pressed, according to the size of the difference and the switch signal of the corresponding button, determine the value according to the preset program. Clicking on the represented characters or informati...

Embodiment 2

[0060] Embodiment 2 (see Figure 2) is a mobile phone of the present technology. There are 18 keys (1) on the keyboard, and the key caps are exposed through the holes in the upper part of the structure (housing), and each key is connected by a rubber film (7), and the part of the rubber film is connected to the on the shell. The lower part of the key is the conductive rubber end (6) of the key. When the key is pressed, the conductive rubber end will contact the conductive film (8) of the printed circuit board on the plate-shaped carrier (integrated with the printed circuit board) contact, turn on the switch circuit, and at the same time transmit the pressure to the plate-shaped carrier (2). There are four stress sensors (4) between the plate-shaped carrier and the bottom plate of the structure (housing), and the sensors can be cheap pressure-sensitive resistors whose resistance value decreases with the increase of pressure. The pressure on the plate-shaped carrier is reflecte...

Embodiment 3

[0062] Embodiment 3 is a kind of watch mobile phone of the present technology, and its keyboard working principle is similar to embodiment 2, but except function key (10), only has 5 character keys to be arranged in a straight line on one side of this mobile phone. Below them is a strip-shaped plate-shaped carrier, which is supported on the bottom plate of the structure (housing) by means of two stress sensors at both ends. The lower part of the character key is the end of the conductive rubber. When the key is pressed, the end of the conductive rubber will contact the conductive film of the printed circuit board on the plate-shaped carrier (integrated with the printed circuit board), and the switch circuit will be turned on. .

[0063] The processing mode and hardware of the switch signal and the pressure signal of the keyboard are basically similar to those of Embodiment 2, but the preset programs related to the input information are different. In the dialing working state,...

Abstract

A sort of equipment with keyboard-inputting function and the inputting method, the structure has one supporting body which carries multiple make-and-break keys, the supporting body can balance and transfer the power or effect received at the keys, the supporting body itself is supported, have a stress sensor which can reflect the continuous variation of the stress it receives; the signal processing line can summarize or dispose the stress signal, get the value of bearing force or the largest value or the increased value when the key is hit, at the same time according to the switch-signal produced by the corresponding key, following the prearrangement confirms the corresponding information, every time it can input different information by hitting the same key.

Description

(1) Technical field: [0001] The invention belongs to the technology of keyboards, computers, hand-held telephones and other devices with information input functions. (two) background technology: [0002] Existing keyboards (including keyboards on devices such as microcomputers and mobile phones) are either too large in size (more keys and faster input speed) and are not easy to carry, or they are small in size (few keys) but have complicated operation methods and are difficult to input. slow. [0003] In order to solve this contradiction, people propose various schemes, all unsatisfactory. For example, in the keyboard scheme provided by CN 2192910Y, a button that can be toggled forward and backward is designed, which can reduce the area occupied by the keyboard keys, but increases the difficulty of finger operation, and the effect is not good. Other schemes using fewer keys, such as those in CN 1264982A, CN 1365041A, CN 1348127A, and CN 1288318A, often require more or more...
