Embodiment Construction

[0048] Please refer to figure 1 and figure 2 . figure 1 A perspective view showing a button according to an embodiment of the present invention, figure 2 drawn according to figure 1 exploded view of the button. Such as figure 1 and figure 2 As shown, the button 100 of this embodiment can be applied to a keyboard device. Furthermore, by changing the size of the button 100 of this embodiment, the button 100 of this embodiment can be used as a square button or a multiple key of a keyboard device, but not This is the limit.

[0049] The button 100 of this embodiment can be composed of a base plate 110, a circuit layer 120, a keycap 130, and a balance bar 140, wherein the base plate 110 can have two hook portions 112 adjacent to two opposite sides of the base plate 110 and opposite to each other and two The first through holes 114 , wherein each hook portion 112 protrudes from the top surface 110 a of the bottom plate 110 and is adjacent to the corresponding first through...

Abstract

The invention relates to a key which comprises a backplane, a circuit layer, a key cap and a balance bar. The backplane is provided with a hook part and a first through hole. The hook part is adjacent to the first through hole. The circuit layer is provided with a first sub layer and a second sub layer. The first sub layer is arranged above the backplane. The first sub layer is provided with a second through hole. The second sub layer is arranged above the first sub layer. The second sub layer is provided with a third through hole. Partial second sub layer extends to a space above the second through hole. A part, which extends to the space above the second through hole, of the second sub layer is defined as a first buffer area block. The first buffer area block comprises at least four area edges. At least two area edges of the first buffer area block are connected with the second sub layer. The first buffer area block is adjacent to the hook part. The balance bar comprises a first bar part and a second bar part. The first bar part is connected with the key cap. The second bar part runs through the hook part. The second bar part of the balance bar is supported by the buffer area block, so that the collision with the backplane is weakened. Volume generated by the pressed key is reduced, so that noise is reduced.

Description

technical field [0001] The invention relates to a button, in particular to a button with noise reduction effect. Background technique [0002] As far as current personal computer usage habits are concerned, the keyboard is one of the indispensable input devices for inputting characters, symbols or numbers. Not only that, but all consumer electronic products in daily life or large-scale processing equipment used in the industry need to be equipped with a key structure as an input device to operate the above-mentioned electronic products and processing equipment. [0003] Generally speaking, most of the keys on the keyboard device are keys with square keycaps (keycap), and a small number of keys such as space key (SPACE), input key (Enter), large character key (CapsLock), shift key (Shift) etc., the length of the keycap is greater than the width, and this type of key is called a multiple key. [0004] The mechanism design of the conventional key mostly includes at least one ...
