Description

Keys and keyboards

technical field

The utility model relates to a key switch and a keyboard using the key switch.

Background technique

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.

See Figure 1. FIG. 1 shows a cross-sectional side view of a key 1 in the background art. As shown in FIG. 1 , the button 1 includes a keycap 10 , a scissors linkage mechanism 12 , an elastic member 14 , a membrane switch 16 and a substrate 18 . The scissor linkage mechanism 12 and the elastic member 14 are respectively disposed between the keycap 10 and the base plate 18 for supporting the keycap 10 .

When the user presses the keycap 10 , the keycap 10 moves downward along with the scissor linkage mechanism 12 and the elastic member 14 , so that the contact portion 120 on the scissor linkage mechanism 12 contacts and turns on the membrane switch 16 . When the user releases the keycap 10 , the keycap 10 can be released by the elastic force of the elastic member 14 , and return to the position before being pressed.

However, due to the structural design of the traditional elastic member 14 , the keycap 10 needs to move for a long distance to make the contact portion 120 on the scissor linkage mechanism 12 contact and conduct the membrane switch 16 . Correspondingly, the user also needs to spend a lot of effort to press the keycap 10 . If the force of the user's pressing is insufficient, so that the downward movement of the keycap 10 is too short, the contact portion 120 on the scissor linkage mechanism 12 cannot contact and conduct the membrane switch 16 . At this time, the user needs to repeatedly press the keycap 10 to complete the desired input function. This is quite inconvenient for users.

Therefore, the scope of the present invention is to provide a button and a keyboard to solve the above problems.

Utility model content

An object of the present utility model is to provide a key, mainly an elastic member with a specific structure is arranged between the key cap and the substrate, when the user presses the key, the key cap can be pressed to the bottom without spending too much effort, that is, The switch on the substrate can be contacted and turned on.

The purpose of the utility model is achieved by providing a key, which includes a key cap, a substrate and an elastic member. There are switches on the substrate. The elastic member is arranged between the keycap and the base plate. The elastic member has a top and a trigger portion corresponding to the switch on the substrate, wherein the top is separated from the trigger portion by a first distance, and the trigger portion is separated from the switch by a second distance, and the first distance is greater than the second distance.

In this embodiment, when the keycap is pressed to move a third distance in the direction perpendicular to the substrate, the trigger portion of the elastic member will be driven to contact the switch on the substrate. It should be noted that, through the structural design of the elastic member, the third distance that the user needs to press will be smaller than the first distance between the top of the elastic member and the triggering portion.

Thus, the trigger portion on the elastic member will contact the switch on the substrate without the user pressing the keycap to the bottom. In other words, the user only needs to lightly press the keycap to complete the desired input function. Therefore, after the user presses the button, the conduction of the switch will be more sensitive.

Another object of the present invention is to provide a keyboard, which includes a casing and a plurality of keys arranged on the casing. The structural design of each key on the keyboard is as described above.

The utility model has the advantage that since the elastic member with a specific structure is arranged between the keycap and the substrate, the trigger part on the elastic member will contact the switch on the substrate without pressing the keycap to the bottom. In other words, the user only needs to lightly press the keycap to complete the desired input function. Therefore, after the user presses the key, the conduction of the switch will be more sensitive.

The advantages and spirit of the present utility model can be further understood through the following detailed description of the utility model and the accompanying drawings.
