Abstract

The utility model relates to a button structure, which comprises a supporting base, a sliding part, a swinging part and a spring. Swinging degree of the swinging part is changed gradually and compression degree of the spring is changed gradually along with descending degree of the sliding part, thereby bringing excellent operating feels to users. When the sliding part descends to a preset stroke, a connecting portion of the swinging part can swing to a circuit component completely, and contacts of the circuit component are then conducted, thereby being capable of avoiding error input caused by the factor of contacting the button mistakenly, and simultaneously improving reliability of buttons.

Description

Press-key structure

Technical field

The structural improvement of the relevant a kind of keyboard of the utility model aims to provide and a kind ofly has preferable operating handle, and press-key structure comparatively reliably.

Background technology

Press, no matter be work or personal use at present, desktop computer and notebook computer have been popularized in general masses' the life, because computer is widely used in various steady news occasions, as information transportation, commercial intercourse, client's communication, document processing and computer graphics etc., so computer is as seen general for the importance of daily life.So, input equipment the most important and next to the shin in computer equipment sees through the button of pushing keyboard and operates then no more than keyboard (keyboard), and program command or data are in time imported in the host computer (host) rapidly easily.Hence one can see that, and how keyboard occupies important position in input operation.

As shown in Figure 1, be the general press-key structure figure of use of the keyboard institute of general PC, this button mainly has a keycap 11, a bracing frame 12 for support keycap 11, and an elasticity coupler body 13 of being located at bracing frame 12 belows relatively, mainly utilize elasticity coupler body 13 to be subjected to compressing of keycap 11 and make the contact conducting of circuit unit 20.

Wherein, elasticity coupler body 13 is for be inverted recessed cup-shaped housing without exception, be provided with one on its enclosure interior summit and couple salient point, when moving downwards touched by user's pressure, this elasticity coupler body 13 promptly is subjected to pressing down and compression of keycap 11, to couple by it that salient point contacts with contact on the circuit unit 20 and the conducting that constitutes this contact use and send the pairing signal of this button, and when user's release is touched the pressure of keycap, its elasticity coupler body 13 can form an elastic reaction and return back to original shape, promptly end sending of signal, and with the state of keycap 11 ejections to rising.

Because, on take off button shown in Figure 1 and mainly utilize the elastic reaction of elasticity coupler body 13 that keycap 11 ejections are returned back to propradation, therefore can to offer user's sense of touch relatively poor, and the useful life of elasticity coupler body 13 is shorter relatively, its conduction contact effect that can provide also desirable not as expection.

The utility model content

The technical problem that the utility model solved is promptly providing a kind of preferable operating handle that has, and comparatively reliable press-key structure.

The technical solution of the utility model is: a kind of press-key structure includes: a supporting seat; One sliding part is sheathed in the middle of this supporting seat, can be subjected to the guiding of this supporting seat and slides up and down displacement according to predetermined stroke, and a wherein avris of this sliding part is provided with an inclined thrust surface; One swing component, be hubbed at the avris of this supporting seat inside with respect to this sliding part, the pivot both sides of this swing component have a junction and a linkage part respectively, this junction stretches in this sliding part descending stroke relatively, this junction is in order to the contact conducting of forming circuit unit, this linkage part is positioned at this sliding part avris relatively, this linkage part for the inclined thrust surface with this sliding part side join to; One spring is located between the junction of this sliding part and this swing component, provide an active force that rises and reset in order to normality to this sliding part, and normality provides an active force that makes its linkage part compress towards the sliding part direction to this swing component.

The beneficial effects of the utility model are: press-key structure of the present utility model includes a supporting seat, a sliding part, a swing component, and a spring; Wherein, sliding part is established and is sheathed in the supporting seat, and can be subjected to the guiding of supporting seat and slide up and down displacement according to predetermined stroke; Swing component is hubbed at the avris with respect to sliding part of supporting seat, the pivot both sides of this swing component have a junction and a linkage part respectively, this junction stretches in the sliding part descending stroke relatively, and this linkage part is positioned at the sliding part avris relatively, for the inclined thrust surface of sliding part side join to.

As for, this spring is located between the junction of sliding part and this swing component, provide an active force that rises and reset in order to normality to sliding part, and normality provides an active force that makes its linkage part compress towards the sliding part direction to swing component.When descended by the external force effect, promptly the linkage part at swing component is subjected under the inclined thrust surface restriction of sliding part, change the swing degree of swing component gradually along with the decline degree of sliding part, and the compression degree that changes spring gradually, make to obtain preferable operating handle.

Especially, when the linkage part of may command swing component is positioned at the inclined thrust surface minimum point of sliding part relatively, the junction side of swing component is able to swing towards the direction of circuit unit fully, the contact conducting of beginning forming circuit assembly, so can effectively avoid causing the phenomenon of improper input to take place, improve the reliability of button simultaneously because of touch of key-press by accident.

According to this, applied to various for example switch or keyboards etc. with regard to whole press-key structure, the utilization of button is with its practical novel versatility of reinforcement mouth.
