Problems solved by technology

However, the metal balance bar is in direct contact with the metal bottom plate, because the contact area between the two is relatively large, so when the keycap moves up and down, the two will collide with each other and produce more obvious noise, so how to effectively design a The keypad device and its keys, and to achieve sufficient structural strength to be used in consumer electronics products with frequent operations has become an important issue

Embodiment Construction

[0055] In order to make the above and other objects, features, and advantages of the present invention more comprehensible, preferred embodiments are listed below and described in detail in conjunction with the accompanying drawings.

[0056] see figure 1 , which represents a schematic diagram of the keyboard device 1 according to an embodiment of the present invention. Such as figure 1 As shown, the keyboard device 1 includes a plurality of keys 20, wherein these keys 20 can be roughly divided into two types: square keys and multiple keys (the length L of the key cap is greater than the width W).

[0057] see next figure 2, which represents an exploded view of the button 20 according to an embodiment of the present invention, the button 20 is, for example, figure 1 The multiple keys in, but the present invention is not limited thereto, and the keys in some embodiments can also be figure 1 The square button in the . Such as figure 2 As shown, the button 20 mainly inclu...

Abstract

The invention provides a keyboard device and a key thereof. The key comprises a key cap, a bottom plate, a balancing bar and a damping sheet, wherein the bottom plate is provided with a clamping hook portion and an accommodating space; a slide groove is formed in the clamping hook portion; the accommodating space is located below the clamping hook portion and is communicated with the slide groove; the balancing bar is connected with the key cap and the bottom plate, so that the key cap can move up and down relative to the bottom plate; when the key cap moves up and down relative to the bottom plate, an end portion of the balancing bar slides in the slide groove; the damping sheet is arranged on the bottom plate and is provided with a body and an extension portion, wherein the extension portion extends from the body so as to cover the accommodating space; when the balancing bar slides in the slide groove, the end portion of the balancing bar contacts with the damping sheet, so that a contact area between the end portion of the balancing bar and the bottom plate can be decreased.

Description

technical field [0001] The present invention relates to a keyboard device and its keys; in particular, it relates to a keyboard device with noise reduction effect and its keys. Background technique [0002] As far as the current usage habits of personal computers are concerned, the keyboard device is one of the indispensable input devices, which can be used to input characters, symbols or numbers. Generally speaking, most of the keys on the keyboard device are keys of square keycaps (key cap), and a small number of keys such as space key (SPACE), input key (Enter), large character key (Caps Lock), shift key ( Shift), etc., the length of the keycap is greater than the width, and this type of key is called a multiple key. [0003] The conventional multiplier key mechanism includes at least one balance bar (balance bar) and a plurality of other components, wherein the balance bar can improve the structural strength of the keycap, so that even if the user presses the non-centra...
