Abstract

The utility model relates to a hinge mechanism for notebook computers, which comprises a fixing nut, a shim group, a bracket, a first spacing shim, a second spacing shim, a shim and a rotary shaft, wherein the end of the rotary shaft is provided with an outer screw thread. The screw thread is orderly penetrated through the shim, the second spacing shim, the first spacing shim, the bracket and the shim group. The fixing nut and the outer screw thread on the end of the rotary shaft are matched. All the components are locked. The first spacing shim is fixed on the bracket, and the second spacing shim and the shim are sheathed on the rotary shaft through a long round hole. The first spacing shim, the second spacing shim and the shim relative to the rotary shaft can not be freely rotated. The first spacing shim relative to the preset position of the surface of the second spacing shim is provided with a round convex point. The second spacing shim is provided with two round spacing convex points on corresponding positions to the round convex point. A groove is formed between the two round spacing convex points for accommodating the round convex point of the first spacing shim.

Description

The linkage of notebook computer

Affiliated technical field

The utility model relates to linkage, relates in particular to a kind of linkage that is used for notebook computer.

Background technology

Generally speaking, the liquid crystal display flat board of notebook computer is fixed among the loam cake of notebook computer by linkage.Loam cake is connected in the main frame of notebook computer by linkage.When using notebook computer, loam cake is opened, to appear the LCD that is mounted thereon.

The general angle of rotating of the LCDs of notebook computer is the 0-180 degree, stops arbitrarily angled.The user uses the hand rotating screen in use to suitable substantially angle, and then gently carries out the suitable angle of being fine-tuning to of front and back with have gentle hands and use.

But for the user, LCD all has a preferable use angle usually with respect to main frame, or the usual angle of using of user, and such as 110 degree, LCD helps protecting user's eyesight in this angle with respect to main frame.

But existing notebook computer can not make the user directly can be opened to suitable angle to LCD, satisfies normal use habit, but need finely tune when forwarding the proper angle left and right sides soon to, and this makes troubles to the user.

The utility model content

The purpose of this utility model is to provide a kind of linkage of notebook computer, and it can make LCD have location hand feeling when forwarding the angle that meets human engineering to, makes the user conveniently be opened to suitable angle to LCD.

The technical scheme that its technical matters that solves the utility model adopts is: the linkage of described notebook computer, and it comprises hold-down nut, support, first spacing shim, second spacing shim and rotating shaft; Second spacing shim, first spacing shim and support are passed in described rotating shaft successively, and nut is fixed in the end of rotating shaft, with above-mentioned each parts locking; Described first spacing shim is fixed in support, and second spacing shim is enclosed within rotating shaft by slotted hole.Described first spacing shim has boss point in the precalculated position with respect to the surface of second spacing shim, second spacing shim has the spacing salient points of two circles putting corresponding position with boss, and two circles are formed for accommodating the groove of the boss point of first spacing shim between the spacing salient points.

Compared with prior art, the utility model LCD can conveniently go to the angle that the user is fit to, and satisfies normal use habit, protection user's eyesight.Finely tune and not be used in when forwarding the proper angle left and right sides soon to.Certainly, there is being specific (special) requirements to need can be screen opening also can to meet the demands during to special angle.

Description of drawings

The utility model is described in further detail below in conjunction with drawings and Examples.

Fig. 1 is the exploded view of linkage of the present utility model;

Fig. 2 is the exploded view of first, second spacing shim of the present utility model;

Fig. 3 is another exploded view of first, second spacing shim of the present utility model.

Embodiment

See also Fig. 1, linkage of the present utility model comprises hold-down nut 1, shim pack 2, support 3, first spacing shim 4, second spacing shim 5, pad 6 and rotating shaft 7.The LCD of notebook computer is fixed in support 3, and the main frame of notebook computer is fixed in rotating shaft 7.One end of rotating shaft 7 has external thread 70.Pad 6, second spacing shim 5, first spacing shim 4, support 3 and shim pack 2 are passed in this rotating shaft 7 successively, and hold-down nut 1 cooperates with the external thread 70 of rotating shaft 7 ends, with each parts locking of the present utility model.First spacing shim 4 is fixed in support 3, the second spacing shims 5 and pad 6 is enclosed within rotating shaft 7 by slotted hole, makes them freely not rotate with respect to rotating shaft 7.

See also Fig. 2 and Fig. 3, first spacing shim 4 has boss point 40 in the precalculated position with respect to the surface of second spacing shim 5.Second spacing shim 5 has between the spacing salient points 50 of the spacing salient points of two circles 50, two circles and forms groove putting 40 corresponding positions with boss, is used to accommodate the boss point 40 of first spacing shim 4.

During use, the user rotates LCD, and first spacing shim 4 together rotates round rotating shaft 7 with support 3, makes LCD forward corresponding angle to.Second spacing shim 5 and pad 6 are nested together by slotted hole and rotating shaft 7, can not relatively rotate.When LCD was rotated, first spacing shim 4 and second spacing shim 5 relatively rotated, and producing friction provides friction force to guarantee that LCD stops at an arbitrary position.Because first,

second spacing shim

4,5 have boss point 40 respectively in the precalculated position, the spacing salient point 50 of circle is so when first spacing shim 4 and second spacing shim 5 forwarded the precalculated position to, the salient point 40 of first spacing shim 4 snapped in the groove between the spacing salient point 50 of circle of second spacing shim 5.At this moment, LCD just is opened to the precalculated position, and the user can obviously feel that the torsion that rotates LCD becomes big simultaneously, and spacing in this position.At this moment, the user knows that LCD has opened to best use angle, can use.

Because boss point 40 and the spacing salient point 50 of circle are not spacing fully, when the user has specific (special) requirements, in the time of need opening to non-precalculated position to LCD, only need when turning to non-precalculated position, increase the power of rotating a little, the spacing salient point 50 of circle that makes the boss point 40 of first spacing shim 4 turn over second spacing shim 5 gets final product, this moment LCD can be opened to arbitrarily angled, the same with other notebook computer.

Notebook computer of the present utility model has location hand feeling when forwarding the angle that meets human engineering to, make the user conveniently be opened to suitable angle to LCD, satisfies normal use habit, protection user's eyesight.Finely tune and not be used in when forwarding the proper angle left and right sides soon to.Certainly, there is being specific (special) requirements to need can be screen opening also can to meet the demands during to special angle.The utility model is easy to open screen to the angle that meets people's use habit, hommization more, the convenient use, and protection user's eyesight.

Those skilled in the art should understand that first spacing shim 4 of the present utility model also can comprise the spacing salient point of two circles, form groove between the spacing salient point of this two circle.Second spacing shim 5 comprises boss point.This structure can realize the purpose of this utility model equally.
