Description
[technical field]
The utility model is about a kind of hinge arrangement, especially about a kind of hinge arrangement that is applied on the portable electron device.
[background technology]
At present, existing portable electron device such as mobile phone can be divided into three kinds of board-type, flip-type and folded forms usually by its external form and structure.Wherein flip-type and Foldable mobile phone generally include body and lid, and lid is rotatably connected on body along its folding direction by a hinge arrangement.
In the prior art, as a kind of existing hinge arrangement that disclosed for No. 99106626 of the Chinese patent that is disclosed on November 24th, 1999, this hinge arrangement comprises a follower, an elastomer and a cam, this cam is provided with protruding peak and trench, this follower also is provided with trench and the protruding peak profile that matches with cam, tool one central shaft on it, central shaft passes cam and elastomer, and follower is connected with cam is rotatable.This cam combines with the mobile phone lid, and cam and its are not relatively rotated, and this follower cooperates with the mobile phone body, and its phone body that relatively moves is not rotated.When the lid phone body that relatively moves opens and closes when moving between the position, cam rotates along the protruding peak and the trench of follower.Because this follower one end profile that is protruding peak of tool and trench shape, it is integrally formed with follower, when follower is cooperated with cam, understands directly contacting, and its contact-making surface is easy to wear, and in addition, the profile on the follower is irregularly shaped, processed complex.
In view of above shortcoming, be necessary to provide a kind of wearing and tearing less, process simple hinge arrangement.
[summary of the invention]
The purpose of this utility model is to provide a kind of wearing and tearing less, processes simple hinge arrangement.
The utility model hinge arrangement comprises an elastomer, a follower, a cam, a card cap, and a sleeve; This follower tool one body; This hinge arrangement further comprises a cylinder, and described body is provided with projection, body one end tool one groove; Described cam has cylindrical portion and cam part, tool one cam surface on this cam part; Described sleeve is provided with chute, the perforate of one end tool; Described cam, cylinder, follower, elastomer place sleeve successively, and the cylindrical portion of cam is exposed to the perforate of sleeve, and cam part is placed in the sleeve; The cam surface of cylinder and cam part and the groove fit of follower, the projection of follower is stretched out by the chute on the sleeve, and elastomer one end supports on follower, and the other end supports on the card cap, and the card cap fixes at the not holed end of sleeve.
Compare prior art, the groove of the utility model hinge arrangement follower cooperates with cylinder, and cylinder cooperates with cam, has avoided follower directly to contact with cam, and has reduced the wearing and tearing of follower mating surface; This cylinder can adopt wear-resisting metal material, thereby reduces the friction of mating surface.In addition, will substitute by cylinder, make the processing of follower simple with the mating surface that former cause follower contacts.

[embodiment]
See also Fig. 1 and Fig. 2, the utility model hinge arrangement 100 is to be applied in folded form or the flip-type mobile phone (figure does not show) that existing lid has body again, and it comprises a card cap 10, an elastomer 20, a follower 30, a cylinder 40, a cam 50 and a sleeve 60.
Elastomer 20 is a helical spring, and the one end supports on follower 30, and the other end supports the end in the 10 tool perforates 102 of card cap.
Cam 50 comprises a cam part 502 and a cylindrical portion 501, and the cam part 502 and the cylindrical portion 501 of this cam 50 are cylindric.
Referring to Fig. 3 and Fig. 4, the utility model hinge arrangement 100 assembling processes are as follows, and cam 50, cylinder 40, follower 30, spring 20 are placed sleeve 60 successively, the perforate 603 that makes the cylindrical portion 501 of cam 50 pass sleeve 60, and stretch out in outside the sleeve 60, cam part 502 is contained in the sleeve; The cylinder 40 of packing into is matched with on the cam surface 503 it; The groove 304 of follower 30 is supported cylinder 40, elastomer 20 1 ends are placed in the rotating shaft 303 of follower 30; Projection 302 inserts in the chute 602; Cover card cap 10 at last, the bayonet lock 101 of card cap 10 is pressed in the draw-in groove 601 of sleeve 60, at this moment, elastomer 20 1 ends are held on the follower 30, the other end is held in an end in the tool hole 102 of card cap 10, and elastomer 20 bears certain precompression, promptly forms a complete hinge arrangement 100.
The positioning relation of hinge arrangement 100 is as follows, and the cylindrical portion 501 of cam 50 is exposed to the perforate 603 of sleeve 60, and cam part 502 is placed in the sleeve 60; Cylinder 40 cooperates with the cam surface 503 of cam part 502 and the groove 304 of follower 30, the projection 302 of follower 30 is stretched out by the chute on the sleeve 60 602, elastomer 20 1 ends support on follower 30, the other end supports on card cap 10, and card cap 10 fixes at sleeve 60 does not have an end of perforate 603.
When this hinge arrangement 100 combines with mobile phone, match with the mobile phone body by the mating surface on the cam 50 504, thereby cam 50 is not rotated with respect to the mobile phone body, the sleeve part of hinge arrangement 100 is contained in the mobile phone lid, match in the projection 302 that exposes by chute 602 and the mobile phone lid from sleeve 60, make follower 30 and mobile phone lid that mutual rotation not take place, and the follower 30 phone lid that relatively moves is slided.
These hinge arrangement 100 user modes are as follows, do not open before the mobile phone lid, be that mobile phone is when being in closed condition, cylinder 40 is positioned at the trench position of cam 50, be stable state this moment, when opening lid when angled, be that cylinder 40 turns to and crosses protruding peak position, this is a labile state, stop the application of force, cylinder 40 moves from next trench position of trend cam 50 under the pressure effect of elastomer 20, drives follower 30 simultaneously and the relative body of mobile phone lid rotates to open mode.When needing the mobile phone closure, to the lid application of force it is rotated relative to body, this cylinder 40 returns at former movement locus, stops the application of force, and the mobile phone lid can be closed automatically.
The cam 50 that is appreciated that this hinge arrangement 100 also can cooperate with the mobile phone lid, and follower 30 matches with the mobile phone body.This hinge arrangement 100 is not limited to be applied on the mobile phone, and it also can be applicable on the portable electron devices such as PDA.
