Description

Keyboard with multiple press positions

The invention relates to a keyboard, in particular to a keyboard with a multi-point pressing position which is light and thin and has multiple points of contact.

With the rapid growth of information technology, electronic devices have become increasingly popular. In terms of computers that are currently used, they can be classified as desktop computers, notebook computers, and tablet computers. In order to increase the speed of computer document processing, most of them need to be equipped with a keyboard for the user to perform character input operations. In terms of the structure of the keyboard, the keyboard mostly has a key cap and a substrate, and a key column is disposed between the key cap and the substrate. When the user taps the keycap, the keypost will support the keycap for vertical movement relative to the substrate. Thereby, when the keycap is pressed, the switch on the substrate can be triggered, and a reference signal is transmitted to the processor to drive the processor to output an appropriate output signal. Further, in order to prevent the user from tapping the two sides of the keycap instead of the central position, the button tilt is unstable, or the switch cannot be triggered. Therefore, the manufacturer has developed a high-sensitivity keyboard so that the user can apply the button even if the force is applied. The switch can still be triggered in the corner.

For example, the high-sensitivity key structure of the Republic of China Invention No. I346965 is mainly provided with a plurality of protruding units on the outer side of the keycap and a plurality of cantilever units on the bottom plate. When the user presses the edge of the keycap, the protruding unit contacts the cantilever unit and causes the free end of the cantilever unit to conduct the circuit switch through the principle of the lever. According to this, even if the button is pressed unevenly, the circuit switch can be actuated, and thus the sensitivity is high.

In addition, the keyboard of the Republic of China Invention No. I396218 is mainly provided with a plurality of touch portions on the keycap and a plurality of switches corresponding to the touch portions on the thin film circuit board. Accordingly, the user only needs to press any corner of the keycap, and the touch portion can press the switch to turn on the switch and output a signal, thereby increasing the sensitivity of the keycap.

The above-mentioned keyboards all support the keycaps by the elastic support frame, and then contact the switches corresponding to the pressing points on the circuit board by the pressing points protruding from the elastic support frames. Further, the keyboards all have elastic support frames, so that the pressing points of the key caps are relatively oscillated with the elastic support frame as a fulcrum. However, the keyboard using the elastic support frame cannot effectively reduce the volume. Moreover, since the key cap supports the elastic support frame, the user must exert a certain force on the key cap to deform the elastic support frame and thereby make the pressing point contact the switch, so even if used The switch cannot be turned on only by gently pressing the corner of the keycap. It can be seen that how to design a lightweight and multi-point contact high-sensitivity keyboard has become a problem to be solved.
