Abstract

The utility model discloses a press key, comprising a bottom plate, a keycap, a lifting mechanism and a limiter. The keycap is arranged above the bottom plate; the lifting mechanism is arranged between the bottom plate and the keycap; a maximum stroke is limited, and the keycap is allowed to perform the vertical motion with respect to the bottom plate. The limiter is positioned, so the keycap is blocked by the limiter while moving respect to the bottom plate; a stroke of the keycap is less than the maximum stroke.

Description

Reduce stroke keys

Technical field

The utility model relates to a kind of button, particularly relates to a kind of reduction stroke keys.

Background technology

Keyboard is applied in various equipment or equipment at large, for example connects computer in order to input characters or numeral.So existing button is defined as button highly consistent for saving cost and simplified design.Yet different occupation modes just can cause further design consideration.Some button has different stroke demands on using, for example two of Trackpad buttons on the notebook computer.When using Trackpad, button also needs to use simultaneously, if two key strokes of Trackpad are oversize, then can prolong the time of button for the user, and the integrated operation fluency also can be affected.

Therefore need button is done a little change under the different frameworks, and a kind of stroke keys that reduces is provided.

The utility model content

A purpose of the present utility model is to provide a kind of reduction stroke keys, to shorten user's button time, increases the fluency of user's operation.

The purpose of this utility model is achieved in that promptly provides a kind of reduction stroke keys, and an a kind of base plate, a keycap, an elevating mechanism and stop part of comprising promptly is provided.Keycap is arranged at the base plate top; Elevating mechanism is arranged between base plate and the keycap, limits a range and moves up and down to allow the relative base plate of keycap.Wherein the setting of stop part is stopped by stop part when making the motion of the relative base plate of keycap, and the motion one stroke, and the stroke that makes the keycap motion is less than range that elevating mechanism limited.

Advantage of the present utility model is, is provided with a stop part, can limit the relative base plate motion of keycap one stroke, reduces key stroke thus, and can shorten user's button time, increases the fluency of user's operation.

Embodiment

The utility model discloses a kind of reduction stroke keys.In order to make narration of the present utility model more detailed and complete, can and cooperate that Fig. 1's to Fig. 4 is graphic with reference to following description.

With reference to figure 1, it discloses the top view of the utility model first specific embodiment, and it comprises Left button 100, and right button 100.Button 100 of the present utility model comprises: a base plate 110, a keycap 120, an elevating mechanism 130 and a stop part 140.Keycap 120 is arranged at base plate top, and elevating mechanism 130 is arranged between base plate 100 and the keycap 120 and moves up and down with permission keycap 120 relative base plates 110.The motion that is arranged so that keycap 120 relative base plates 110 of stop part 140 is stopped.

With reference to figure 2, it is the end view of button 100 among Fig. 1.Have a range 170 between keycap 120 and the base plate 110, this range 170 is the ultimate range that keycap can move relative to base plate 110.Range 170 is determined by the lifting structure 130 between base plate 110 and the keycap 120.That is, when being subjected to any stopping, keycap 120 can not support the ultimate range of moving because of elevating mechanism 130 to base plate 110.And the utility model is provided with a stop part 140 and protrudes on the base plate 110 in order to reduce the stroke of keycap 120 motions.This stop part 140 has an outstanding length 142, distance that decision keycap 120 moves and the stroke that can reduce.When keycap 120 when base plate 110 moves, before reaching range 170, run into stop part 140 earlier, because of stopping of stop part 140, make movement travel 180 that keycap 120 carried out less than range 170, reach the purpose that reduces stroke.

With reference to figure 3, it is the schematic diagram after keycap 120 moves one stroke.When keycap 120 when base plate 110 moves, because of touching stop part 140 stop motions.The distance that this moment, keycap 120 was moved is the movement travel 180 among Fig. 2.Stop part 140 links with base plate 110 with being formed in one in the present embodiment.That is stop part 140 is the upwards part of bending of base plate 110.Can be the assembly that separates at another embodiment stop part 140 and base plate 110.

With reference to figure 4, it is the utility model second specific embodiment, and wherein the set position of stop part 240 and first specific embodiment is different.This embodiment is arranged at keycap 120 bottoms with stop part 240, equally also can reach the effect that reduces stroke.Have a range 170 between keycap 120 and the base plate 110, this range 170 is the ultimate range that keycap can move relative to base plate 110.Range 170 is determined by the lifting structure 130 between base plate 110 and the keycap 120.In order to reduce the stroke of keycap 120 motions, a stop part 240 is set protrudes in keycap 110.This stop part 240 has an outstanding length 142, distance that decision keycap 120 moves and the stroke that can reduce.When keycap 120 when base plate 110 moves, before reaching range 170, stop part 240 will be conflicted base plate 110 and because of stop part 240 stops earlier, makes movement travel 180 that keycap 120 carried out less than range, reaches the purpose that reduces stroke.

In this embodiment, schematic diagram and Fig. 3 of moving behind the one stroke of key lid 120 is similar.When keycap 120 when base plate 110 moves, because of stop part 140 touches base plate 110 stop motions.The distance that this moment, keycap 120 was moved is the movement travel 180 among Fig. 2.Stop part 240 also can link with keycap 120 or the element for being connected individually one-body moldedly in addition.

With reference to figure 2, in another embodiment, button 100 still comprises a supporting part 150, is used for the support arm 160 of supporting elevation mechanism 130 again.Because stop

part

140 or 240 are set, therefore cause when keycap 120 is installed to elevating mechanism 130, keycap 120 can be subjected to stopping of

stop part

140 or 240 and make grab (not shown) on the keycap can't be engaged to the support arm 160 of elevating mechanism.Therefore, when this keycap 120 is installed in elevating mechanism 130, ask high support arm 160 can make the grab (not shown) of keycap 120 be enough to engage the hole clipping (not shown) on the support arm 160.So can assemble keycap 120 easily to lifting structure 130.Supporting part 150 is to link with base plate 110 one-body moldedly in addition.
