Abstract

The utility model discloses a spindle bracket which can be folded automatically, comprising a first fixed seat which is connected with a pedestal, a second fixed seat which is connected with an upper cover, an automatic folding unit which is provided with a fixed plate with a dent and a rotary plate with a protrusion, and a rotation shaft with one end provided with a raised block to be sleeved with the second fixed seat and the other end provided with a bearing and stretching into the first fixed seat and the automatic folding unit. Since the dent on the fixed plate of the automatic folding unit and the protrusion on the rotary plate are matched with each other, when a user rotates the upper cover towards the pedestal, the second fixed seat and the rotation shaft are both driven to rotate, while when the protrusion on the rotary plate is rotated into a position where the protrusion on the rotary plate can be jointed with the dent on the fixed plate during rotation, the torque force disappears at the moment that the protrusion joints with the dent, then under the effects of gravity and force, the upper cover will close automatically towards the pedestal under, thus reaching the purpose of folding the spindle bracket automatically.

Description

Automatically fold pedestal design

Technical field

The utility model relates to a kind of pedestal design that folds automatically, especially refer to that a kind of recess by fixed plate matches with the protuberance of rotary piece, when user's application of force rotary upper cover when base rotates, also driving second fixed base and rotating shaft simultaneously rotates with rotary piece, when the protuberance of this rotary piece revolves the recess of putting fixed plate and engages, the moment that this protuberance engages with recess, can make the torsion pop-off, and then make the factor of loam cake because of active force and gravity, and loam cake is closed toward the base direction voluntarily, and then reach a kind of purpose that folds pedestal design automatically.

Background technique

As, TaiWan, China patent gazette certificate number M297005 number " notebook computer and rotary shaft mechanism thereof ", it comprises: an axle sleeve; One axle center is arranged in this axle sleeve in rotatable mode; One driven member is connected in this axle center, and is driven by this axle center; One opposing structure is arranged on by this driven member;

See also Fig. 8 of TaiWan, China patent gazette certificate number M297005 number " notebook computer and rotary shaft mechanism thereof ", it resists structure (being torque spring) as can be known, though it can work as the axle center when rotating in first angular range, driven member follows the axle center to rotate together, but can not touch the opposing structure, so the time required operation torsion less, and when the axle center rotates in second angular range, driven member will be contacted with the opposing structure and be subjected to resistance, this moment, required operation torsion increased, can change because of angle of swing is different and reach the required operation torsion of rotary shaft mechanism, the user can open and close screen easily;

Yet, the external force that all relies on the user of opening and close of being somebody's turn to do " notebook computer and rotary shaft mechanism thereof " is reached purpose, under the situation that requires automation now, can not satisfy the Consumer fully, and if user's careless manipulation or be eager to close screen, thereby, apply too big external force and can make the screen quick-make, to produce compressing to notebook computer and rotating mechanism thereof, cause reduce the working life of rotating mechanism, again, notebook computer is opened the back and is produced torsion to support the angle after opening by the mechanism that produces torsion entirely, so when the user is permanent use after, the mechanism that produces torsion will can't provide support the torsion after the unlatching gradually, thereby cause the screen of notebook computer sagging automatically and can't firmly fix;

How above-mentioned disappearance is forgone, and provide a kind of only need apply after the external force can the auto-closing display device fold pedestal design automatically, be the place of the technical difficulties that the present utility model people institute desire solves.
