Problems solved by technology

[0004] However, since the switch 15 on the circuit board 14 is triggered by pressing the keycap 12 to make the trigger portion 19 of the elastic member 18 press down, the circuit board 14 and the elastic member 18 will relatively bear relatively large compressive stress, thereby As a result, the pressing feel of the button 1 is not sensitive enough and the service life of the elastic member 18 is affected. Furthermore, if the user presses improperly and the circuit board 14 is subjected to excessive compressive stress, the circuit board 14 may appear. Permanent deformation, resulting in damage to the circuit or continuous triggering of switch 15, etc.

Embodiment Construction

[0057] see figure 2 , image 3 ,as well as Figure 4 , figure 2 It is an enlarged schematic diagram of some keys 102 of the keyboard 100 proposed according to an embodiment of the present invention, image 3 for figure 2 internal schematic of the keypad 102, Figure 4 for image 3 The top view of the button 102. Such as figure 2 , image 3 ,as well as Figure 4 As shown, the keyboard 100 includes a plurality of keys 102, in order to clearly show the key structure design of the keyboard 100, in figure 2 Only a single button 102 , a bottom plate 104 , and a rebound device 106 are shown in FIG. The key 102 includes a keycap 108 (which is used in image 3 as well as Figure 4 shown in dotted line) and the supporting device 110, and the button 102 is arranged on the bottom plate 104 for the user to press to perform the function that the user wants to input. The bottom plate 104 has a trigger elastic arm 112 and is opposite to the trigger elastic arm 112. The trigg...

Abstract

The invention relates to a key and a keyboard thereof. The key comprises a base plate, a key cap, a support device and a spring-back device, wherein the base plate is equipped with a trigger elastic arm and a trigger switch; the support device comprises a first support component and a second support component; the first support component is pivoted with the key cap and is in sliding connection with the base plate; the second support component is pivoted with the base plate and is in sliding connection with the key cap and is pivoted with the first support component in a crossing form; one of the first support component and the second support component is in contact with the elastic arm; the spring-back device is arranged between the key cap and the base plate and is used for driving the key cap to return; when the key cap is pressed by an external force, one of the first support component and the second support component relatively outward slides so as to drive the elastic arm to trigger the trigger switch; when the external force is released, the key cap is driven by the spring-back device to move back to the un-pressed position; one of the first support component and the second support component relatively inward slides so as to drive the elastic arm to separate from the trigger switch. The key provided by the invention can solve the problems of pressing hand feel of the key and the service life of the elastic component in the prior art.

Description

technical field [0001] The present invention relates to a key and its keyboard, in particular to a key and its keyboard which uses a trigger elastic arm on a bottom plate to slide along with a support to separate from a trigger switch or trigger the trigger switch. 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] see figure 1 , which is a cross-sectional view of the key 1 in the prior art. Such as figure 1 As shown, the button 1 includes a bottom plate 10 , a keycap 12 , a circuit board 14 , a lifting support device 16 and an elastic member 18 . The circuit board ...
