Description
Technical field
The utility model relates to a kind of hinge, particularly relates to a kind of limit hinge that reaches the angle limit effect in hinge pivot stroke.
Background technique
The electronic equipment of general drawing-pushing type on the market is as notes computer, mobile phone etc., mainly utilizes hinge with the winding that is pivoted of the display device of electronic equipment and main frame body.During use, after raising, can operate the relative main frame body of display device; And when not using, display device also relatively the doubling of main frame body fold.By the setting of hinge, significantly dwindle the volume of electronic equipment, with the effect that reaches convenient for collecting and carry.But above-mentioned hinge must be provided with a position-limit mechanism, can reach spacing effect when the relative main frame body of display device is raised, and prevents that display device from raising the excessive impaired or appearance damage of transmission line that causes between display device and main frame body of angle.
In present existing technology, shown in TaiWan, China M328173 number and M327152 patent case, the hinge that above-mentioned two patent cases are disclosed is provided with the limit effect of position-limit mechanism when pivoting to reach hinge.Wherein, M328173 patent case discloses a kind of notes computer pivot, include the connection set that a part and is hubbed at this part, this part one end is combined with a body that is used to be assembled on the product, and form an axial region to wear a pad that changes with this part synchronizing shaft at the relative the other end of this body, and this connection set has a supporting element that is pivoted this axial region, and this supporting element has block that should pad, and offseting by this pad and this block when this part axle is changeed forms spacing relation.
M327152 patent case also discloses a kind of notes computer pivot, includes a part, and this part one end is combined with one for the body that is assembled on the product, and this part is formed with the axial region of a noncircular cross section in contrast to an end of this body; One supporting element, this supporting element one end forms one for the joint that is assembled on the product, this supporting element forms a pin-joint part in contrast to an end of this joint, this pin-joint part is articulated in the axial region of this part, wherein, this part has a limited ring, and this limited ring is provided with a corresponding restraining groove and a block with this supporting element, and this part can be butted on this block by this restraining groove when this supporting element rotates relatively and reach limit effect.
The something in common of above-mentioned two patent cases is, this two patents case all is provided with block on the supporting element that is hubbed at a part, in order to reach spacing effect, but, need apply the external force punching press during making in a side of supporting element and just can protrude the formation block, cause the supporting element out-of-flatness, and reduce the area of contact of supporting element and both sides pad at opposite side, frictional force deficiency when causing rotating, and supporting element stressed when rotation more cause the phenomenon damaged because of surface irregularity produces unbalance stress.
Moreover because the trend of miniaturization of electronic products, the volume of axle part and supporting element also dwindles thereupon, cause on the supporting element space limited and can't be at its position again application of force punching press produce other block, therefore can't make the spacing pivot of providing littler angle of swing.
In addition, the pivot that above-mentioned two patent cases are disclosed, only the pad by supporting element and its both sides forms the frictional force of two surface of contact so that rotation to be provided, and causes the very few and hypodynamic problem that rubs of surface of contact quantity.
This shows that above-mentioned existing hinge limit structure obviously still has inconvenience and defective, and demands urgently further being improved in structure and use.In order to solve the problem of above-mentioned existence, relevant manufacturer there's no one who doesn't or isn't seeks solution painstakingly, but do not see always that for a long time suitable design finished by development, and common product does not have appropriate structure to address the above problem, this obviously is the problem that the anxious desire of relevant dealer solves.Therefore how to found a kind of novel hinge limit structure, real one of the current important research and development problem that belongs to, also becoming the current industry utmost point needs improved target.
