AI Technical Summary

Benefits of technology

The present invention is about a new keyswitch and keyboard that detects how far the keys are moved. This allows for different levels of sensitivity depending on the user's needs. The keyboard can detect how many times the keys are moved, and can determine if the keys are pressed regularly or intermittently. This helps the computer recognize different types of touch and can adjust its response accordingly. The keyboard is also compact, as it uses a distance detecting unit instead of a spring, which makes it suitable for thin-typed electronic devices.

Problems solved by technology

However, the electronic switch of the conventional mechanical keyswitch is actuated by pressing the keycap to deform the actuating spring, and deformation of the actuating spring is able to actuate the electronic switch since a relative movement between the keycap and the base is greater than a specific distance, so that the mechanical keyswitch has long operation stroke and large structural volume and is unsuitable for consumer thin-typed electronic product.

Embodiment Construction

[0016]Please refer to FIG. 1 to FIG. 3. FIG. 1 is a diagram of a keyboard 10 according to an embodiment of the present invention. FIG. 2 and FIG. 3 respectively are sectional views of a keyswitch 12 in different operation modes according to a first embodiment of the present invention. The keyboard 10 may have a plurality of keyswitches 12, and each of the keyswitches 12 has distance detecting function and may be have any specific type according to design demand. The keyswitch 12 includes a base 14, a keycap 16, a supporting component 18, a recovering component 20, a distance detecting unit 22 and a sheltering component 28. The base 14 is a circuit board disposed inside the keyboard 10. The keycap 16 is an interface where the user presses; a symbol mark is printed on the keycap 16 to distinguish the symbol command of the keyswitch 12. The keycap 16 can be made of light penetrating material. The supporting component 18 has a first end 181 and a second end 182 opposite to each other. T...

Abstract

A keyboard with a distance detecting function includes a plurality of keyswitches, and each keyswitch includes a keycap, a base, a supporting component, a recovering component and a distance detecting unit. The base has a guide slot structure. The supporting component has a first end connecting to the keycap, and a second end movably assembled with the guide slot structure. The recovering component is disposed between the supporting component and the guide slot structure. The distance detecting unit is detachably disposed on the base, and adapted to detect a movement of the keycap relative to the base for determining whether the keyswitch is actuated.

Description

BACKGROUND OF THE INVENTION[0001]1. Field of the Invention[0002]The present invention relates to a keyswitch and a keyboard, and more particularly, to a keyswitch and a keyboard with the distance detecting function.[0003]2. Description of the Prior Art[0004]A conventional mechanical keyswitch includes a base, a keycap, a recovering component and an actuating spring. The recovering component is disposed on the base, the keycap is installed on the recovering component, and the keycap can be vertically moved relative to the base via manual pressure. The actuating spring is disposed by the keycap. The keycap moves relative to the base to contact the actuating spring while arrives a specific position, and the actuating spring drives an electronic switch to output a control command corresponding to the mechanical keyswitch. The actuating spring further provides a resilient recovering force to the keycap for hand feeling. However, the electronic switch of the conventional mechanical keyswi...
