Description

Rotary hinge

Technical field

The utility model relates in particular to a kind of rotary hinge that is applied to thinned electronic relevant for a kind of rotary hinge.

Background technique

Between the display device of general thinned electronic and the keyboard hinge means is arranged all, required torsion when providing the relative keyboard of display device to raise, make rapid progress along with Information technology, occurred a kind of make display device not only relatively keyboard raise and hinge structure that can axial rotation.

Announce M325719 number as TaiWan, China, M285184 number described technology, the common point of these two technology is, all comprise a positioning seat, one can be relatively the master of this positioning seat rotation revolve seat and a rotating part that is positioned at this positioning seat below, wherein, positioning seat is provided with at least one containing part, dispose at least one touch part in this containing part and be positioned at this touch part top and Flexible element inconsistent with touch part, containing part comprises at least one perforation, touch part is positioned in the perforation and exposes to containing part, at least one groove is set on the rotating part, in the master was revolved the rotating distance of seat, touch part and revolving part were to the top system and with respect to perforation generation upper and lower displacement.

Make groove break away from touch part though above-mentioned two technology drive rotating part in the time of can revolving the seat rotation by the master, the torsion when rotating is provided whereby; But positioning seat need be provided with assembling space in addition with the installing elastic element, thereby it is excessive to cause rotary hinge thickness to increase volume, can not satisfy the demand of pursuing compact electronic equipment now.

For improving above-mentioned technology existing rotary hinge technology has as shown in Figure 1 been arranged just, comprise that mainly an assembled plate 70, passes and be located in the rotary seat 80 and one and the affixed Location resilient piece 90 of rotary seat 80 1 end faces of assembled plate 70, wherein be equipped with a spacing catch 72 below assembled plate 70, spacing catch 72 is fixed in assembled plate 70 belows by a fixed plate 71; Below rotary seat 80, be provided with bond post 83, one supplementary plate 81 is arranged between rotary seat 80 and the assembled plate 70, this supplementary plate 81 is provided with the conjugate foramen 84 that is complementary with bond post 83 positions and quantity, and supplementary plate 81 peripheries convex with one and can resist the spacing block set 82 that forms spacing relation mutually with spacing catch 72; Between assembled plate 70 and Location resilient piece 90, be provided with a friction plate 91.

Above-mentioned existing rotary hinge technology, though can improve the problem that causes product thickness to reduce because of volume is excessive, but still there are the problem of complex structural designs in supplementary plate 81, friction plate 91, fixed plate 71 and spacing catch 72, the bond post 83 that rotary seat 80 belows are convexly equipped with, when engaging with the conjugate foramen 84 of supplementary plate 81, the bad problem of coupling often takes place, and promptly can produce idle running or unstable situation of rocking in rotating distance.

The model utility content

The purpose of this utility model is to provide a kind of rotary hinge, is applied in the thinned electronic, so that it is bad to solve in the prior art coupling, and promptly can produces idle running or instability problem such as rock in rotating distance.

Described rotary hinge comprises that mainly an assembled plate, passes and be located in the rotary seat and one and the affixed Location resilient piece of rotary seat one end face of assembled plate, and assembled plate is between rotary seat and Location resilient piece, and the relative assembled plate of rotary seat has rotating distance; Wherein assembled plate is provided with at least two locating slots, Location resilient piece be provided with to should locating slot quantity and with the positioning convex portion of locating slot coupling, and rotary seat is provided with a rail groove of making the rotating distance amount in advance, be provided with spacing salient point in the rotating distance with respect to this rail groove on the assembled plate, rotary seat interlock Location resilient piece in rotating distance rotates, positioning convex portion and locating slot break away from and oppress the temporary transient deformation generation restoring force of Location resilient piece and rotary torsion is provided, and slip into locating slot by positioning convex portion and form positioning relation, and spacing salient point directly forms spacing relation in the rail groove.

Compare with prior art, the utlity model has following advantage:

1, assembling is simplified and be easy to structure, effectively reduces manpower and the Material Cost of producing;

2, in rotating distance, do not have idle running or unstable problem generation of rocking.
