Abstract

The utility model discloses a key, which comprises a bottom plate, a key cap, a lifting mechanism and a blocking part. The keycap is arranged above the bottom plate; the lifting mechanism is arranged between the base plate and the keycap and limits a maximum stroke to allow the keycap to move up and down relative to the base plate. The blocking part is arranged to block the keycap from the blocking part when the keycap moves relative to the base plate, and the keycap moves by a stroke which is smaller than the maximum stroke.

Description

Button to reduce travel

technical field

The utility model relates to a button, in particular to a button with a reduced stroke.

Background technique

Keyboards are widely used in various equipment or devices, such as connecting to a computer for inputting characters or numbers. In order to save costs and simplify the design of the existing keys, the keys are limited to be of the same height. However, different ways of use will cause further design considerations. Some keys have different travel requirements, such as the two keys on the touchpad of a notebook computer. When using the touchpad, the buttons also need to be used at the same time. If the travel of the two buttons on the touchpad is too long, it will prolong the time for the user to press the buttons, and the overall smoothness of operation will also be affected.

Therefore, under different architectures, it is necessary to make some changes to the buttons, and provide a button that can reduce the stroke.

Utility model content

An object of the present invention is to provide a button with a reduced stroke, so as to shorten the time for the user to press the button and increase the fluency of the user's operation.

The purpose of the utility model is achieved by providing a key with a reduced stroke, that is, providing a key that includes a bottom plate, a key cap, a lifting mechanism and a blocking portion. The keycap is arranged above the bottom plate; the lifting mechanism is arranged between the bottom plate and the keycap, limiting a maximum stroke to allow the keycap to move up and down relative to the bottom plate. Wherein the blocking portion is set so that the keycap is blocked by the blocking portion when moving relative to the bottom plate, and moves a stroke, so that the moving stroke of the keycap is smaller than the maximum stroke defined by the lifting mechanism.

The utility model has the advantage that a blocking part is provided, which can limit the movement of the keycap relative to the bottom plate by a stroke, thereby reducing the stroke of the button, shortening the time for the user to press the button, and increasing the fluency of the user's operation.

Detailed ways

The utility model discloses a button with a reduced stroke. In order to make the description of the present utility model more detailed and complete, reference may be made to the following description together with the diagrams in FIGS. 1 to 4 .

Referring to FIG. 1 , it discloses a top view of a first embodiment of the present invention, which includes a left button 100 and a right button 100 . The button 100 of the present invention includes: a bottom plate 110 , a keycap 120 , a lifting mechanism 130 and a blocking portion 140 . The keycap 120 is disposed above the bottom plate, and the lifting mechanism 130 is disposed between the bottom plate 100 and the keycap 120 to allow the keycap 120 to move up and down relative to the bottom plate 110 . The setting of the blocking portion 140 makes the movement of the keycap 120 relative to the bottom plate 110 blocked.

Referring to FIG. 2 , it is a side view of the key 100 in FIG. 1 . There is a maximum stroke 170 between the keycap 120 and the bottom plate 110 , and the maximum stroke 170 is the maximum distance that the keycap can move relative to the bottom plate 110 . The maximum stroke 170 is determined by the lifting structure 130 between the bottom plate 110 and the keycap 120 . That is, the maximum distance that the keycap 120 can move toward the bottom plate 110 due to the support of the lifting mechanism 130 when there is no obstruction. In the present invention, in order to reduce the movement stroke of the keycap 120 , a blocking portion 140 is provided to protrude from the bottom plate 110 . The blocking portion 140 has a protruding length 142 , which determines the moving distance and the lowering stroke of the keycap 120 . When the keycap 120 moves toward the bottom plate 110, it first touches the blocking portion 140 before reaching the maximum stroke 170. Due to the blocking of the blocking portion 140, the movement stroke 180 of the keycap 120 is smaller than the maximum stroke 170, thereby reducing the stroke. .

Referring to FIG. 3 , it is a schematic diagram of the keycap 120 after moving for a stroke. When the keycap 120 moves relative to the bottom plate 110 , it stops moving due to touching the blocking portion 140 . At this time, the distance moved by the keycap 120 is the motion stroke 180 in FIG. 2 . In this embodiment, the blocking portion 140 is integrally connected with the bottom plate 110 . That is, the blocking portion 140 is a part of the bottom plate 110 bent upward. In another embodiment, the blocking portion 140 and the bottom plate 110 may be separate components.

Referring to FIG. 4 , it is a second specific embodiment of the present invention, wherein the position of the blocking portion 240 is different from that of the first specific embodiment. In this embodiment, the blocking portion 240 is disposed at the bottom of the keycap 120 , which can also achieve the effect of reducing the stroke. There is a maximum stroke 170 between the keycap 120 and the bottom plate 110 , and the maximum stroke 170 is the maximum distance that the keycap can move relative to the bottom plate 110 . The maximum stroke 170 is determined by the lifting structure 130 between the bottom plate 110 and the keycap 120 . In order to reduce the movement stroke of the keycap 120 , a blocking portion 240 is provided protruding from the keycap 110 . The blocking portion 240 has a protruding length 142 , which determines the moving distance and the lowering stroke of the keycap 120 . When the keycap 120 moves toward the bottom plate 110, before reaching the maximum stroke 170, the blocking portion 240 will first touch the bottom plate 110 and be blocked by the blocking portion 240, so that the movement stroke 180 of the keycap 120 is less than the maximum stroke, reaching a reduced stroke. the goal of.

In this embodiment, the schematic diagram of the key cover 120 after a stroke is similar to FIG. 3 . When the keycap 120 moves relative to the base plate 110 , it stops moving because the blocking portion 140 touches the base plate 110 . At this time, the distance moved by the keycap 120 is the motion stroke 180 in FIG. 2 . In addition, the blocking portion 240 and the keycap 120 can also be integrally connected or individually connected components.

Referring to FIG. 2 again, in another embodiment, the button 100 further includes a supporting portion 150 for supporting the arm 160 of the lifting mechanism 130 . Due to the setting of the blocking portion 140 or 240, when the keycap 120 is installed to the lifting mechanism 130, the keycap 120 will be blocked by the blocking portion 140 or 240, so that the hook (not shown) on the keycap cannot be engaged with the lifting mechanism 130. The arm 160 of the mechanism. Therefore, when the keycap 120 is installed on the lifting mechanism 130 , the lifted arm 160 can make the hook (not shown) of the keycap 120 enough to engage with the hole (not shown) on the arm 160 . In this way, the keycap 120 can be easily assembled to the lifting structure 130 . In addition, the supporting portion 150 and the bottom plate 110 are connected integrally.
