Description

Hinge arrangement

[technical field]

The utility model is about a kind of hinge arrangement, refers in particular to a kind of being installed in electronic equipment pedestal and the loam cake, make the electronic equipment loam cake relatively its pedestal do twin shaft to the rotation and the good hinge arrangement of positioning of rotating.

[technical background]

Along with electronic industry constantly develops, flexibility, convenience when electronic equipment uses are more and more paid attention to by the user, at present, such as numerous electronic equipments such as notebook computer, PDA, mobile phone, e-dictionaries, usually adopt loam cake to support display screen with a hinge arrangement, and hinged with pedestal, this display screen is overturn before and after this pedestal relatively with loam cake.

With the notebook computer is example, and at present the progress of the state-of-the-art technology on the notebook computer display screen all is to develop at improving the information vision definition direction that the single operation person directly is sitting in before the keyboard.And the loam cake and the hinge arrangement between pedestal that install display screen in the existing notebook computer are improved the also most flexible actions and accurate location of how to realize or improving front and back upset between this loam cake and pedestal that are limited to, promptly mainly be to improve the notebook computer hinge arrangement that is disclosed for No. 01144543.2 as Chinese patent application to the hinge of rotation to only doing single shaft.But when the notebook computer operator need be to other people's exhibition information, these people need crowd in the computer back, and the notebook computer display screen is corresponding less, in the case, if need when showing, bring inconvenience unavoidably more than one or two people.In addition, if unexpected removable computer also might cause the magnetic head damage when hard disk rotates.

The structure that No. the 470115th, No. the 01144305.7th, other hinge-like structure such as Chinese patent application and No. 00265045.2, Taiwan patent announcement etc. are disclosed.

But the existing at present dealer of industry proposes the relative pedestal twin shaft of electronic equipment loam cake to Rotation Design, as No. the 99110803.5th, Chinese patent application, this hinge arrangement is installed in notebook computer loam cake and the pedestal, comprise that one is coupled on the pedestal and makes the loam cake can be around first piece of horizontal plane upset, one connects this first piece and horizontal axis and this loam cake can be reached one and be located at the support that in this loam cake second piece is connected with vertical axis around rotating second piece of a vertical axis.

But, this type of design only can provide loam cake to return turnback around vertical axis clockwise by the dead ahead, if the operator needs when other people shows with counterclockwise 0-180 degree, then can not reach, and owing to do not have location structure in this design, so in the vertical axis rotary course, can not reach positioning of rotating at loam cake.In addition, this type of design hinge assembly structure complexity, volume is bigger, is against portable product such as notebook computer and reduces volume and weight, improves portable development trend.

Therefore, the hinge arrangement of electronic equipments such as notebook computer is improved, to eliminate above-mentioned shortcoming.

[summary of the invention]

The rotary hinge arrangement that technical problem to be solved in the utility model is to provide is one simple in structure, the location is good, be installed in make this electronic equipment behind the electronic equipment loam cake relatively its pedestal do twin shaft to rotatablely moving.

Technical problem to be solved in the utility model is achieved through the following technical solutions: the utility model hinge arrangement comprises a holder, the one rotatable swivel base that is installed in this holder, one places the connector between this holder and this swivel base, one is bonded to the conjunction of this holder with this swivel base, and the keeper of a good location when realizing motion between this holder and swivel base.This holder comprises a body, and one protrudes out the boss of providing locating hole from this body, some fixed parts that extend to form from this body bottom; This swivel base comprises that one can embed the auxiliary section in this holder, one platform that extends to form by this auxiliary section end face, one barrel that extends to form downwards by this platform outer rim and be located at the arm that this barrel periphery can link to each other with this loam cake respectively, and the excircle of this auxiliary section is provided with some locating slots, and this arm comprises that one has the turning arm of rotational structure; The auxiliary section that this keeper passes positioning screw hole and swivel base on the holder cooperates and contacts, and it comprises a housing, and one places the spring and of this housing to place this housing and suppresses ball on this spring.

During operation, upset electronic equipment loam cake, can reach loam cake by the rotation of this turning arm is the first axially upset of axle with this swivel base arm; And another axially on, rotate this loam cake, the spring stress compression of keeper by the rolling of this ball at this holder inwall, makes swivel base drive loam cake around himself axis rotation, when ball sinks in the locating slot on this swivel base, can realize positioning of rotating.

In addition, be respectively equipped with a projection on this holder and the swivel base, establish a screens portion in this connector, the three matches, and the relative pedestal of this electronic equipment is spent to 180 degree rotations-180.

The utility model hinge arrangement makes relative its pedestal of the loam cake of electronic equipment can carry out twin shaft to rotation, promptly except that the upset of routine, also increased around second and axially spent to the rotation of 180 degree from-180, the design of its locating slot and keeper simultaneously makes rotation can realize the location on different directions, and good sense of touch when keeping rotation by the elastic force between ball and spring control, thereby it is make positioning of rotating stable, and simple in structure, easy to operate.
