Abstract

The utility model relates to an improved type of keyboard bridge structure which comprises a first connector and a second connector which is pin-jointed with the first connector. An inclined plane part is arranged at the bottom part of a pin-jointed groove of the first connector and the second connector. The bottom part of a pivot is provided with another inclined plane part, the juncture of the two inclined plane parts forms a fulcrum, when jacking the keycap with elastic elements, the position of the fulcrum is fixed in the centre, and sets the fulcrum as the cycle center movement with the changing of angles. Moreover, during the process of moving, the movement clearance does not expand synchronously, and when the keycap is pressed downwards, the fulcrum also acts with a fixed centre point to support and transfer the lateral force bearing when the keycap is pressed downwards. Thus the roll angle and falter can be effectively reduced.

Description

The modified keyboard is built bridge and is constructed

Technical field

The utility model relates to a kind of modified keyboard bridge formation structure, particularly a kind of bridge formation structure that side tilt angle and degree of rocking can effectively be reduced.

Background technology

Known, employed bridge formation is constructed (shown in Fig. 1-1～1-4 on the notebook computer keyboard at present, also be the computing machine key structure utility model patent of No. the 301431st, the bulletin before applied for of applicant in Taiwan) be by first, two

connectors

1,2 constitute, described first, two

connectors

1,2, has a foot 11 on it, 21, this

foot

11,21 both sides respectively have one symmetrical first 12,22, this first 12,22 are articulated in the snapping portion of pedestal, in addition in

foot

11,21 undertake two

symmetrical arms

14,24, at two arms 14, a hole 15 is arranged between 24,25, and at arm 14, one articulated section 16 is arranged on 24,26, this articulated

section

16,26 by a pivot connected

slot

17,27 and one

pivot

18,28 form, and at two arms 14, an end of 24 has one

symmetrical second

10,20, this

second

10,20 are articulated in the snapping portion of keycap.

When first and

second connector

1,2 horizontal, two articulated sections are the situation of mutual complete cooperation, but when keycap being made progress jack-up along with flexible member, the position of fulcrum can with angle change and on move, meeting generation activity tolerance clearance condition of enlarged in moving, and the lateral pressure the when keycap that also can't have a strong strong point transmission to be born when pressing down presses down, side tilt angle and to rock angle bigger when causing keycap to press down, the joint of first and

second connector

1,2 is broken away from, and the situation that keycap rocks easily or gets loose, jumps out of take place.

Summary of the invention

Fundamental purpose of the present utility model is to solve the shortcoming of above-mentioned conventional construction, avoids the existence of shortcoming, and the utility model makes the structure of building bridge through redesign, allows and builds bridge when action, the bridge formation structure that side tilt angle and degree of rocking can effectively be reduced.

In order to achieve the above object, mainly be first, has an articulated section on two arms of two connectors, this articulated section is made up of a pivot connected slot and a pivot, described pivot connected slot has a chamfered portion on the bottom, and the bottom of pivot has another chamfered portion, the intersection of these two chamfered portions forms a fulcrum, when along with flexible member during with keycap jack-up, the stationkeeping of this fulcrum is at mid point, along with angle changes and is center of circle action with the fulcrum, the free gap does not enlarge thereupon in moving, and when keycap is pressed down, also with a fixing central point action, the side force when supporting keycap that transmission bears and pressing down, this side tilt angle and rock and can effectively reduce.

Relevant technology contents of the present utility model and structure now are described with reference to the accompanying drawings as follows:

Embodiment

Fig. 2 is a bridge formation stereoscopic decomposing schematic representation of the present utility model, as shown in the figure: modified keyboard of the present utility model is built bridge to construct and is comprised: one first connector 1, with second connector 2 that articulates with described first connector 1, it is configured between the pedestal (not shown) and keycap (not shown) of keyboard, in order to the bridge formation structure of carrying keycap knee-action.

The first above-mentioned connector 1, has a foot 11 on it, these foot 11 both sides respectively have one symmetrical first 12, this first 12 snapping portion (not shown) that is articulated in pedestal, and in this foot 11, have one with the protuberance 13 of the lean against part (not shown) of pedestal assembling, undertake two symmetrical mutually arms 14 in foot 11 in addition, between two arms 14, has a hole 15 that supplies elasticity element (not shown) to pass, and on arm 14, has an articulated section 16, this articulated section 16 is made up of a pivot connected slot 17 and a pivot 18, described pivot connected slot has a chamfered portion 171 on 17 bottoms, and the bottom of pivot 18 has another chamfered portion 181, these two chamfered portions 171,181 intersection forms a fulcrum 19, have one symmetrical second 10 at an end of two arms 14 again, on the snapping portion (not shown) that this second 10 is articulated in keycap;

This second connector 2, has a foot 21 on it, these foot 21 both sides respectively have one symmetrical first 22, this first 22 snapping portion (not shown) that is articulated in pedestal, and in this foot 21, has a protuberance 23, undertake two symmetrical arms 24 in foot 21 in addition, between two arms 24, has a hole 25 that supplies the elasticity element and first connector 1 to pass, and on arm 24, has an articulated section 26, this articulated section 26 is made up of a pivot connected slot 27 and a pivot 28, described pivot connected slot has a chamfered portion 271 on 27 bottoms, and the bottom of pivot 28 has another chamfered portion 281, these two chamfered portions 271,281 intersection forms a fulcrum 29, and have one symmetrical second 20 at an end of two arms 24, on the snapping portion (not shown) that this second 20 is articulated in keycap.Like this, just constituted a brand-new keyboard bridge formation structure.
