Abstract
The utility model discloses the pivot device of a kind of cam and utilization thereof, be arranged at the hinge axis of notebook, it comprises discoid body, be positioned in the middle part of described body with the elongated hole of described hinge axis interference fit, be positioned at least one projection of described body one side surface, the curved surface that described elongated hole comprises a pair circular arc and the locating face coordinated with described hinge axis plat part for a pair, described locating face and described curved surface connecting part are provided with escape groove, because the utility model have employed escape groove between curved surface locating face, friction can be reduced in cam slide, alleviate the Strike note of pad, eliminate pivot device abnormal sound.
Description
Technical field
the utility model relates to notebook, the pivot device of particularly a kind of cam and utilization thereof.
Background technique
the screen of some electronic equipments needs to arrange bearing support and stands on regularly on desktop with certain angle to make it, as computer screen, also be easy to folding simultaneously between this bearing support and screen thus be convenient to deposit, and this is generally arrange pivot device to realize by connecting between bearing support and screen.Existing pivot device is mainly by the incompatible realization of cam set as above function, and it only can make screen rotation realize self-locking, under screen is merely able to be fixed on this angle in use to during some angles.In order to ensure that screen does not loosen, interference fit is needed to be connected between cam with hinge axis, but because the hinge axis of interference fit cam and pivot device exists the frictional force hindering cam again axle to slide, when pivot device works, due to the existence of this frictional force, cam impinges upon on pad or another cam of matching when overcome friction is slided, produce and clash into sound or abnormal sound, have impact on the use of electronic equipment.And when frictional force is excessive, the cooperation between two cams can be affected, cause pivot device to loosen.
Summary of the invention
the purpose of this utility model is to provide a kind of cam and the pivot device that can overcome abnormal sound.
for achieving the above object, the technical solution adopted in the utility model is: a kind of cam, be arranged at the hinge axis of notebook, it comprises discoid body, be positioned in the middle part of described body with the elongated hole of described hinge axis interference fit, be positioned at described body one side surface at least one is protruding, the curved surface that described elongated hole comprises a pair circular arc and the locating face coordinated with described hinge axis plat part for a pair, described locating face and described curved surface connecting part are provided with escape groove.
described locating face and described hinge axis interference fit.
described locating face is also provided with the straight trough connecting described locating face both sides escape groove, described straight trough and described locating face stepped.
described projection arranges two.
described body side is provided with oil storage tank.
a kind of pivot device using above-mentioned cam.
because technique scheme is used, the utility model compared with prior art has following advantages:
because the utility model have employed escape groove between curved surface locating face, friction can be reduced in cam slide, alleviate the Strike note of pad, eliminate pivot device abnormal sound.
Accompanying drawing explanation
accompanying drawing 1 is the utility model cam schematic diagram;
accompanying drawing 2 is the utility model cam schematic diagram;
accompanying drawing 3 is the utility model pivot device schematic diagram.
in above accompanying drawing: 1, body; 2, protruding; 3, curved surface; 4, locating face; 5, escape groove; 6 straight troughs.
Embodiment
below in conjunction with embodiment shown in the drawings, the utility model is further described:
embodiment one: shown in accompanying drawing 1, a kind of cam, be arranged at the hinge axis of notebook, it comprises discoid body 1, be positioned in the middle part of body 1 with the elongated hole of hinge axis interference fit, at least one projection 2 being positioned at body 1 one side surface, the curved surface 3 that elongated hole comprises a pair circular arc and the locating face 4 coordinated with hinge axis plat part for a pair, locating face 4 and curved surface 3 connecting part are provided with escape groove 5, escape groove 5 can reduce friction in cam slide, alleviate the Strike note of pad, eliminate pivot device abnormal sound.
the edge part of elongated hole is provided with chamfering, to be easy to install.
locating face 4 and hinge axis interference fit, locating face 4 is comparatively easily processed for plane, adopts locating face 4 and hinge axis interference fit to reduce difficulty of processing.
locating face 4 is also provided with the straight trough 6 connecting locating face 4 both sides escape groove 5, and straight trough 6 is stepped with locating face 4.
protruding 2 arrange two, and centrosymmetric projection can make body 1 uniform stressed.
body 1 side is provided with oil storage tank 7, for storing machine oil.
a kind of pivot device using above-mentioned cam.
above-described embodiment, only for technical conceive of the present utility model and feature are described, its object is to person skilled in the art can be understood content of the present utility model and implement according to this, can not limit protection domain of the present utility model with this.All equivalences done according to the utility model Spirit Essence change or modify, and all should be encompassed within protection domain of the present utility model.
