Description

Press-key structure

Technical field

The utility model is about a kind of press-key structure, especially in regard to a kind of press-key structure of slight keyboard.

Background technology

In conventional art, the button lid below of the press-key structure of keyboard can be provided with scissors shape structure, this scissors shape structure can provide a restoring force to the button lid, by this restoring force, when the pressure that puts on this button side of covering was removed by power, this button lid can be raised to an initial position by this restoring force.Simultaneously, this scissors shape structure is covered in the process that moves up and down this button, can keep good stable.

Yet at difform button lid, scissors shape structure Design also needs corresponding change (keyboard can need the scissors shape structural design more than three kinds usually), and at different scissors shape structures, needs different moulds and made.Therefore, use scissors shape structure can promote the manufacturing cost of keyboard.

The utility model content

The purpose of this utility model is exactly to provide a kind of press-key structure for desire solves the problem of conventional art, comprises that a film circuit board, a substrate, a pressure are touched assembly, a button covers and a connecting rod.Film circuit board comprises that a signal produces point.Substrate comprises an articulated section and one first limiter assembly.Pressure is touched assembly and is arranged on this signal generation point.The button lid comprises a junction and one second limiter assembly.Connecting rod articulates this articulated section, and connect this connecting portion, wherein, when this button lid is positioned at a primary importance, this this second limiter assembly of first limiter assembly butt, when this button lid is subjected to a pressed by external force and when being positioned at a second place, this pressure is touched assembly and is pressed and touch this signal and produce point and produce a signal of telecommunication.

The advantage of the utility model device is, uses press-key structure of the present utility model, can replace traditional scissors shape structure by connecting rod, makes moving up and down of button lid energy balance and stability.Simultaneously, the restoring force of press-key structure is then touched assembly by pressure provides.The utility model is specially adapted to the press-key structure design of slight keyboard, because the stroke of the press-key structure of slight keyboard is shorter, therefore only touching assembly by pressure can provide enough restoring forces, and provides the button stability that lid moves by connecting rod of the present utility model simultaneously.

Embodiment

With reference to Fig. 1 a, it comprises that for showing the press-key structure 100 of the utility model first embodiment a film circuit board 110, a substrate 120, a pressure are touched assembly 130, a button covers 140 and one connecting rod 150.Film circuit board 110 comprises that a signal produces point 111.Substrate 120 comprises articulated section 121 and one first limiter assembly 122.Pressure is touched assembly 130 and is arranged on this signal generation point 111.Button lid 140 comprises connecting portion 141 and one second limiter assembly 142.Connecting rod 150 articulates this articulated section 121, and connects this connecting portion 141.

When this button lid 140 was positioned at a primary importance P1, this this second limiter assembly 142 of first limiter assembly, 122 butts limited moving of button lid 140 whereby, avoided 140 displacements of button lid or upset.With reference to Fig. 1 b, when this button lid 140 is pushed by an external force F and when moving as for a second place P2, button lid 140 pushes away and makes this pressure touch assembly 130 to press and touch this signal and produce point 111 and produce a signal of telecommunication.

When this button lid 140 when this primary importance P1 moves to this second place P2, this connecting rod 150 is switched to a second orientation (orientation that Fig. 1 b is shown) from a first orientation (orientation that Fig. 1 a is shown).

First limiter assembly 122 and second limiter assembly 142 are cantilever beam.First limiter assembly 122 passes substrate 120.When button lid 140 is positioned at this primary importance P1, this substrate 120 of first limiter assembly, 122 butts and this second limiter assembly 142.When button lid 140 was positioned at this second place P2, first limiter assembly 122 fell and the butt state of releasing and this substrate 120.

With reference to Fig. 2 a, connecting rod 150 is rectangular, and comprises a breach 151, is formed at one side of this rectangle, and the material of connecting rod 150 is a metal.With reference to Fig. 2 b, it is the stereogram of press-key structure 100 of the present utility model, and it is the be connected situation of demonstration connecting rod 150 with articulated section 121 and connecting portion 141.In embodiment of the present utility model, mode that connecting rod 150 can articulate or fixing mode connect this connecting portion 141.

It is a cheese assembly (Dome) that pressure is touched assembly 130, and its material can be rubber.This pressure is touched 130 pairs of this button lids 140 of assembly an elastic force is provided, so that this button lid 140 returns back to this primary importance P1 from this second place P2 automatically.

With reference to Fig. 3, it is for showing the press-key structure 100 ' of second embodiment of the present utility model, its characteristics are, connecting rod 150 ' comprises one first section portion 152 and one second section portion 153, this first section portion 152 connects this second section portion 153, and has an angle between this first section portion 152 and this second section portion 153.Connecting rod of the present utility model can also be bent into other shape.

With reference to Fig. 4 a, it is for showing the 3rd embodiment of the present utility model, and wherein, this button lid 140 also comprises a protuberance 143, and this pressure is touched the cheese assembly (Dome) that assembly 130 ' is a metal material, and 143 pairs of this protuberances should be pressed and be touched assembly 130 '.With reference to Fig. 4 b, when this button lid 140 is pressed by to this second place P2 the time from this primary importance P1, protuberance 143 pushes away and makes this pressure touch assembly 130 ' to press and touch this signal and produce point 111 and produce a signal of telecommunication.

Use press-key structure of the present utility model, can replace traditional scissors shape structure by connecting rod, make moving up and down of button lid energy balance and stability.Simultaneously, the restoring force of press-key structure is then touched assembly by pressure provides.The utility model is specially adapted to the press-key structure design of slight keyboard, because the stroke of the press-key structure of slight keyboard is shorter, therefore only touching assembly by pressure can provide enough restoring forces, and provides the button stability that lid moves by connecting rod of the present utility model simultaneously.

Of the present utility modelly replace traditional scissors shape structure with the metal connecting rod, because connecting rod is simple in structure, with low cost, the therefore manufacturing cost that can significantly save press-key structure.And because the metal connecting rod is easy to bending, therefore distortion can conveniently be applicable to various press-key structure design easily.

Though the utility model with concrete preferred embodiment openly as above; right its is not in order to limit the utility model; any insider; in not breaking away from spirit and scope of the present utility model; still can do a little change and retouching, therefore protection range of the present utility model is as the criterion when looking claims person of defining.
