Description

Pivot structure

[technical field]

The utility model is about a kind of pivot structure, refers in particular between a kind of pedestal and lid that is installed in electronic equipment, makes the relative pedestal of lid of electronic equipment do twin shaft to pivoting and can realizing the pivot structure of good location.

[prior art]

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 lid to support display screen with a pivot structure, and hinged with pedestal, this display screen is overturn before and after this pedestal relatively with lid.

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 lid and the pivot structure 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 lid and pedestal that are limited to, promptly mainly be to improve the notebook computer pivot structure 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.

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 pivot structure 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, 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 pivot structure of electronic equipments such as notebook computer is improved, to eliminate above-mentioned shortcoming.

[summary of the invention]

That the purpose of this utility model is to provide is one simple in structure, the location is good, realize that twin shaft is to the pivot structure that pivots.

The utility model pivot structure is used to realize that the relative pedestal of lid of electronic equipment pivots, and it comprises one first inverted impulse body and one second inverted impulse body.This first inverted impulse body comprises relatively turnable one first transfer part and one second transfer part, and this first transfer part is fixed on this lid.This second inverted impulse body comprises a holder, a rotatable swivel base that is installed in this holder, and one places the connector between this holder and this swivel base, reaches the keeper of good location when moving between this holder of realization and swivel base.This holder comprises that one is provided with the body of through hole, and this body is established one first projection at last ora terminalis; This swivel base rotates and is contained in the through hole of this holder, and it establishes a linking arm and one second projection, and second transfer part of this linking arm and this first inverted impulse body fits together; This connector is installed between this swivel base and this holder, and it is provided with one and the screens portion that cooperates of this first projection and second projection, and this keeper contact generation and locatees with this swivel base.This first inverted impulse body makes relative this pedestal of this lid can make pitch rotation, and this second inverted impulse body rotates this lid 180 degree about the axis of vertical this pedestal is done.

The utility model pivot structure makes relative its pedestal of the lid of electronic equipment can carry out twin shaft to rotation, promptly except that the pitching upset of routine, the relative pedestal of this electronic equipment is spent to the left rotation and right rotation of 180 degree-180.In addition, establish positioning piece in this pivot structure and contact cooperation generation location with this swivel base.Thereby make pivot structure tool positioning stablity of the present utility model, and advantage simple in structure, easy to use.
