Embodiment Construction

[0052] see figure 1 as well as figure 2 , figure 1 It is a partially enlarged schematic diagram of an embodiment of a keyboard according to the present invention, figure 2 for figure 1 Schematic diagram of the partial explosion of the bottom plate and diaphragm, magnet and thin-film circuit board. In order to clearly show the mechanism design of the key 12, the key cap 14 is in the figure 1 Indicated in dashed lines. The keyboard 10 includes a plurality of keys 12 (in figure 1 shown in, but not limited to) and base plate 16. The keys 12 are disposed on the bottom plate 16 for users to press to perform corresponding input operations. The keys 12 include a key cap 14 , a diaphragm 15 , a support device 18 , a magnet 20 and a thin film circuit board 22 . It should be noted that the keyboard 10 can be preferably applied to a portable electronic device (such as a notebook computer or a foldable keyboard device) that generally has an opening and closing mechanism composed o...

Abstract

The present invention relates to a key and a keyboard thereof. The key includes a keycap, a supporting device, a magnet, a bottom plate having an opening, a diaphragm attached to the bottom plate to form an accommodating groove with the opening, and a thin film circuit board; the supporting device is arranged between the bottom plate and the keycap and comprises a first supporting component; a magnetic plate component is bent and extends from the first supporting component and is located above the accommodation groove; the magnet is disposed in the accommodation groove; the thin film circuit board is disposed on the bottom plate and at least partially covers the upper surface of the magnet to fix the magnet in the accommodation groove; when the keycap is pressed to make the magnetic plate component move away from the magnet with the pivoting of the first supporting component, the keycap moves to a pressed position; and when the keycap is released, the magnetic attraction force of the magnetic plate component and the magnet makes the magnetic plate component approach the magnet, so that the keycap can return to a non-depressed position. According to the key of the invention, fixing design according to which the magnet is fixed in the accommodation groove by means of the thin film circuit board is adopted, so that the magnet can be fixed to the bottom plate even if the bottom plate is in a weak magnetic or non-magnetic condition.

Description

technical field [0001] The present invention relates to a key and a keyboard thereof, in particular to a method of arranging a magnet in an accommodating groove formed by a diaphragm and an opening of a bottom plate and using a thin-film circuit board to at least partially cover the upper surface of the magnet to fix the magnet on the The keys in the receiving slot and their keyboard. Background technique [0002] As far as the current usage habits of personal computers are concerned, the keyboard is one of the indispensable input devices for inputting characters, symbols or numbers. Not only that, for example, consumer electronic products that are used in daily life or large-scale processing equipment used in the industry all need to have a key structure as an input device to operate the above-mentioned electronic products and processing equipment. [0003] Generally, the traditional keyboard adopts a pressing design in which the assembly structure of the scissor foot supp...
