Description

The combination button device

[technical field]

The utility model relates to a kind of key device, particularly relates to a kind of combination button device.

[background technology]

Present electronic product generally all can comprise combination button, such as the navigation key on the mobile phone, the directionkeys on the projecting apparatus, the menu function key on the e-dictionary or the like.This class combination button function is simple and clear, is easy to use.

Traditional combination button generally is divided into four functional areas, is controlled by buttons upper and lower, four parts in a left side and the right side accordingly.But the button distance of each function area part is near, and the situation that mistake is pressed takes place easily, and integral keyboard is easy to generate interlock, when pushing the button of a function area part, may drive the button of other function area part, cause misoperation and combination button result of use not good.

Therefore, traditional combination button device lacks the structure that prevents the button interlock.

[utility model content]

Based on this, be necessary to provide a kind of combination button device that can prevent the keyboard interlock.

A kind of combination button device comprises key body, fixture and base plate.This key body have press surface and with the opposing installed surface of this press surface.This installed surface is provided with button and touches part and joint pin.This joint pin tilt towards the middle part of this key body and with the angle of this installed surface be acute angle.This fixture offers the installing hole of accommodating this key body on it.This fixture also comprises on the hole wall of being located at this installing hole and the fixed part that matches with this joint pin.This base plate comprises with this button and touches the key contacts that part matches, and this button touches the part generation control signal that contacts with this key contacts, and this key body is fixed on this base plate by this fixture.

General combination button device is divided into a plurality of functional areas.If all these joint pins are vertical with this installed surface, when then pushing a certain functional areas of this key body, this joint pin of being located at these two edges, functional areas can be perpendicular to this installed surface motion, and near the motion of the functional areas can driving.Because all these joint pins are parallel to each other, so the motion of other functional areas is not interrupted, so this key device can produce interlock.Situation when the situation of above-mentioned interlock also appears at all these joint pin almost parallels.Direction away from this press surface tilts if all these joint pins are all to this key body center, then still can realize the effect of button, and when pushing some functional areas of this key body, thereby though be located near can move the functional areas motion driving of this joint pin at these two edges, functional areas, the athletic meeting of other functional areas is interrupted.At this moment, this key body is away from the end meeting perk of the functional areas that are pressed, and promptly this key body tilts to the function area part of being pushed.Therefore, this key device can carry out effective button operation, has the interlock of preventing to produce simultaneously.

Further, it is a plurality of that this button touches part, and this joint pin is a plurality of, and this key body is divided into a plurality of functional areas, is equipped with this button in each these functional areas and touches part, and per two these adjacent functional areas intersections are equipped with this joint pin.

Be equipped with this button in each these functional areas and touch part, guaranteed to push each these functional areas and can both produce the button effect.Every two adjacent these functional areas intersections also are provided with this joint pin, have at least two these joint pins directly stressed when guaranteeing to push some functional areas, are produced misoperation thereby reach the functional areas that effective button hinders other simultaneously by drive.

Further, this joint pin is near the edge of this key body, and this joint pin is along periphery interval, the evenly distribution of this key body.

Each this joint pin evenly distributes at interval along the periphery of this key body, and when pushing some functional areas, this joint pin at two edges that is positioned at these functional areas is stressed evenly, makes this key body in that receive can be not crooked when pushing.And simplicity of design, easy to manufacture.

Further, the angle of this joint pin and this installed surface is 45 degree.

Can reach and prevent that this case device from producing the interlock effect, makes again easily.

Further, this fixed part is a plurality of curved elasticity muscle, and the middle part is fixed on the hole wall of this installing hole, and two ends offer the perforate of inserting for this joint pin.

When pushing some functional areas of this key body, these functional areas are sent control signal to the direction motion and the inclination that are pressed thereby make this button touching that is positioned at these functional areas contact this key contacts.Pressing force disappears behind end of operation, this elasticity muscle that deformation taken place recover initial state and the time this key body rebound, make this button touching and this case contact separately, realize effective button operation, the feel in the time of can also guaranteeing button simultaneously.The design of the shape of this elasticity muscle; guarantee that this key body this elasticity muscle when being subjected to pushing is enough to take place deformation and makes this button touch part can to contact with this key contacts, Wan Zhe shape can protect this elasticity muscle can not damage under excessive forces effect and pressing operation repeatedly simultaneously.

Further, also be provided with acknowledgement key on this fixture, this acknowledgement key is fixed in this installing hole by elastic strip, this elastic strip comprises line part and the bend that links to each other with this line part, this line part is fixed in the hole wall of this installing hole away from an end of this bend, this bend is fixedlyed connected with this acknowledgement key around this acknowledgement key extension and its end away from line part, and the middle part of this key body offers the keyhole that is used to accommodate this acknowledgement key.

The setting of this acknowledgement key makes easy to operately, meets the custom of general use button, uses simple.Design is extended in the bending of this elastic strip, has promptly guaranteed the button effect of this acknowledgement key, has guaranteed to change elastic strip again and can not damage under excessive forces effect and pressing operation repeatedly.

Further, this acknowledgement key is provided with leads electric contact unit, and this base plate is provided with this and leads the conductive contact that electric contact unit matches.

This is led electric contact unit and this conductive contact and also can contact and send control signal, thereby realizes the affirmation selection function of acknowledgement key.

Further, offer through hole on this fixture, also be provided with function key on this fixture, this function key is fixed in this through hole by the elasticity rib, and this function key is provided with function key and touches part, and this base plate is provided with this function key and touches the function key contact that part matches.

This function key can be used as an integral body together with this acknowledgement key and this key body, and self-contained back one is installed, and makes simple, easy for installation.

Further, also be provided with dismountable transparency window that is used for the light derivation of button indicator light on this fixture.

Can pass through for the light of light sources such as the start indicator light in the instrument that uses this combination button device, keyboard lockout lamp, thereby make the user better grasp the behaviour in service of this instrument.

Further, the edge of this key body also is provided with latch, also is provided with gathering sill on the hole wall of this installing hole, thereby this latch can fasten with this gathering sill this key body is fastened on this fixture.
