Abstract
The invention discloses a kind of brake chip pivot structure of notebook computer, mainly by axle sleeve, central shaft, fan-shaped brake piece group, circular brake piece, shell fragment, and the part such as fastening nut is formed, because the damping torsion that the rotating shaft has when rotating results from the rubbing surface of fan-shaped brake piece and circular brake piece, therefore suitable damping torsion can be obtained in less volume, and this torsion can be by being adjusted to torsion regulating nut and fastening nut, and mandrel is misaligned in use and produces friction damage, in addition, because this pivot structure is compact to design, be not in use oil leakage phenomenon.
Description
Technical field
The present invention relates to the pivot structure used in notebook computer, more particularly to a kind of brake chip pivot structure.
Background technology
With the development of notebook computer technology, requirement of the people to its important mechanical part technical performance also constantly carries
Height, for the pivot structure as central link part, gives a variety of designs, and wherein China Patent Publication No. is
Two technical schemes proposed in CN202991827U and CN102996616A two parts of files have than more typical representative
Property, although above-mentioned technical proposal all preferably solves problem present in the respective background technology, traditional design
Theory still leaves the shortcoming in mechanism to pivot structure.
The shortcomings that above-mentioned pivot structure, is essentially divided into two major classes, and one kind is to rely on to rub between central shaft and sleeve assembly
Caused radial direction damping force is converted into supporting the torsion of laptop computer displays part, and the stress fatigue point of such a structure is concentrated
In on central shaft, central shaft is constantly wearing with use, is changed once damage is difficult maintenance.Another kind of is to utilize axial rub
Axle provides damping force centered on shell fragment, must to obtain the torsion of support display enough because the rubbing surface of its shell fragment only has one
Surely there are enough axial compressive forces, also with regard to required enough shell fragments, thus cause central shaft is long can make affiliated product
Global design is restricted, and more because above two design exist structure leakage can in use caused by oil leakage phenomenon, these lack
Point can all make troubles to user.
The content of the invention
It is an object of the present invention to jumping out traditional design mode uses brake chip principle, by central shaft and different brake pieces
Be combined among axle sleeve, the rotating part integral assembling of rotating shaft in axle sleeve, make the rotary action radius of central shaft from its own
Radius expands to total radius of axis of rotation part, and as rotating part itself part brake piece the brake piece to be rubbed with it
Between existing coefficient of friction suitable damping torsion is provided when being rotated for pivot structure, can effectively protect again central shaft not with suit
Part produces friction damage, and oil leakage phenomenon is avoided the occurrence of with this close closed structure.
To realize the above-mentioned purpose of the present invention, there is provided following technical scheme：
A kind of brake chip pivot structure is designed, its primary structure includes：Axle sleeve, central shaft, fan-shaped brake piece group, circular brake
The parts such as piece, shell fragment and fastening nut are formed.The axle sleeve is hollow cylindrical, and appearance and size determines overall pivot structure
Space occupy-place, and provide installation site for miscellaneous part；The central shaft string wears circular brake piece, shell fragment and the fastening nut
Slip cap is loaded in the axle sleeve, and locks installation site by fastening nut；The fan-shaped brake piece group passes through perpendicular to axle center
Through hole is arranged on axle sleeve, is mutually extruded its mutual coefficient of friction with the friction surface of the circular brake piece and is carried for pivot structure
For appropriate damping torsion；The circular brake piece is set in the central shaft, by the shell fragment and fastening nut elastic compression in
Among axle sleeve, the rubbing surface of its rubbing surface and the fan-shaped brake piece in the fan-shaped brake piece group is matched and the offer of this pivot structure is provided
Damp torsion.
Preferably, it is anon-normal circular cylinder that the central shaft, which passes through the stage casing position of circular brake piece, to drive the circle
Brake piece, which rotates, provides torsional moment.
Preferably, the anon-normal circular cylinder of the middle hole shape and the central shaft of the circular brake piece mirrors, by center
The rotary action radius of axle extends to the radius of circular brake piece.
Preferably, the frictional contact surface of the circular brake piece and fan-shaped brake piece is the thin wedge shape of middle webbing, so as in elasticity
There is both during compression maximum contact surface.
Preferably, the fan-shaped brake piece group is made up of fan-shaped brake piece, disc spring and torsion regulating nut, wherein fan-shaped brake piece quilt
Disc spring elasticity is fitted in the through hole set on the axle sleeve, changes disc spring to sector brake by rotating regulation torsion regulating nut
The pressure of piece, so as to adjust the coefficient of friction between brake piece.
Preferably, the fan-shaped brake piece group be more than one group, when for it is multigroup when be uniformly distributed along the axle sleeve radial circumference,
Enough coefficient of friction are provided for the circular brake piece.
Preferably, the fan-shaped brake piece bottom front for wedge shape in order to push when coefficient of friction is adjusted, side
Face makes it obtain the friction area of maximum when being contacted with the circular brake piece for sector.
A kind of brake chip pivot structure of the present invention, because it has big rubbing surface in structure, while coefficient of friction can
It is adjusted on demand, and central shaft is in use without friction loss, overall structure small volume, in the absence of leakage point, effectively
Solves problem present in prior art.
