Abstract
The utility model discloses a fixing rack of a liquid crystal display; the fixing rack comprises a metal frame, wherein a plurality of supporting legs are extended from the periphery of the metal frame downwardly; and torsion pawls capable of being twisted are arranged at the bottom of the supporting legs. When the fixing rack is used for fixing the liquid crystal display, the metal frame covers the liquid crystal display, the supporting legs pass through a mounting member on the back of the liquid crystal display, and the torsion pawls are extended out and twisted to clamp the mounting member, so that the liquid crystal display is clamped between the metal frame and the mounting member on the back to realize the fixing. The fixing rack is low in production cost, simple in display and installation operation, and low in process cost. Meanwhile, the torsion pawls cannot be loosened due to the vibration, and have excellent vibration resistance.
Description
Technical field
The utility model relates to the fixed support of the anchor fitting of Liquid Crystal Display (LCD), particularly a kind of vehicle LCD.
Background technology
Can use Liquid Crystal Display (LCD) in the vehicle-mounted equipment such as auto meter, car multimedia; These Liquid Crystal Display (LCD)s are connected with circuit card through the zebra bar usually; In order to guarantee the good conducting of Liquid Crystal Display (LCD) and circuit card; The zebra bar need keep certain stress deformation, and this fixed sturcture to Liquid Crystal Display (LCD) has proposed higher requirement.Fig. 1 is a kind of fixed sturcture of Liquid Crystal Display (LCD), and it comprises the metal frame that covers the Liquid Crystal Display (LCD) edge, and the edge of metal frame is provided with screw hole, and the metal frame that will cover Liquid Crystal Display (LCD) through screw is fixed on the member at Liquid Crystal Display (LCD) back; It can be more firm the immobile liquid crystal display, but fixing operation is inconvenient, the technology cost is high.Fig. 2 is the fixed sturcture of another kind of Liquid Crystal Display (LCD), and it comprises a plurality of metal card bases that stretch out that are provided with around metal edge frame and the metal edge frame downwards; Through metal edge frame cover on Liquid Crystal Display (LCD) around, the metal card base embeds in the draw-in groove of installation component at Liquid Crystal Display (LCD) back, and Liquid Crystal Display (LCD) is clamped between metal edge frame and the back member; This fixed sturcture, easy for installation, cost is low, but card base is easily because of frequent vibration gets loose, and the deflection of zebra bar can't keep, thereby can't keep the reliable conducting between Liquid Crystal Display (LCD) and zebra bar and circuit card; It is used to vibrate in the frequent automobile, and is reliable inadequately.The said fixing structure also can adopt plastic cement to make, and its card base is difficult for getting loose under the environment of frequent vibration, and is fixing reliable; But it need make special-purpose plastic mould, and cost of manufacture is high; And the plastic cement card base grinds trickle plastics powder easily under the environment of frequent vibration, and these fine-powders possibly get into and attached on circuit card or the zebra bar, and the conducting of circuit card and Liquid Crystal Display (LCD) and circuit card is brought harmful effect.
Summary of the invention
The utility model is intended to provide that a kind of cost is low, easy for installation, fixation is reliable, can anti-vibration and can not bring the fixed support of dysgenic Liquid Crystal Display (LCD) to circuit card.
The fixed support of the described Liquid Crystal Display (LCD) of the utility model comprises metal framework, and the metal framework periphery is extended with a plurality of feets downwards, and the bottom of feet is provided with the coilable pawl of turning round.
The fixed support of the described Liquid Crystal Display (LCD) of the utility model, during the immobile liquid crystal display, metal framework covers the periphery of Liquid Crystal Display (LCD); The feet that stretches out downwards passes installation components such as the lamp box, circuit card at Liquid Crystal Display (LCD) back; Turn round pawl and stretch out, turn round the pawl certain angle, make and turn round pawl and block installation component; Thereby Liquid Crystal Display (LCD) is clamped between metal framework and the back installation component, thereby realizes the fixing of Liquid Crystal Display (LCD).Its fitting operation is simple, convenient, and the technology cost is low; And whole anchor fitting is a metal construction, can process through the simple operations of punching press, flange, and cost of manufacture is also low; Simultaneously; That reverses turns round pawl and can not unclamp because of vibration, can be good at the opposing vibration, on the frequent automobile of vibration, can keep solid and reliable fixing; The deflection that keeps zebra bar between Liquid Crystal Display (LCD) and circuit card, make the zebra bar all the time with circuit card and the reliable conducting of Liquid Crystal Display (LCD); In addition, it can not produce micro powder yet, can not bring harmful effect to the conducting of circuit card and Liquid Crystal Display (LCD) and circuit card.

The specific embodiment
A kind of fixed support of Liquid Crystal Display (LCD) like Fig. 3, comprises metal frame 1, and the metal framework periphery is extended with a plurality of feets 2 downwards, and the bottom of feet is provided with the coilable pawl 3 of turning round.During immobile liquid crystal display 4, like Fig. 4, metal framework covers the periphery of Liquid Crystal Display (LCD); The feet that stretches out downwards passes members such as the filter 5, lamp box 6, pcb board 7 at Liquid Crystal Display (LCD) back successively; It is turned round pawl and stretches out the behind at pcb board, turns round the pawl certain angle, makes to turn round pawl and be clamped on pcb board behind; Thereby Liquid Crystal Display (LCD), filter, lamp box, pcb board etc. are snapped together, thereby realize the fixing of Liquid Crystal Display (LCD).
Around the said metal frame downward flange arranged, its can through flange from around cover Liquid Crystal Display (LCD), better fixing display, avoid telltale to around be subjected to displacement.
Through being placed on zebra bar 8 conductings in the lamp box, Liquid Crystal Display (LCD) and zebra bar joint need be avoided being subjected to displacement between Liquid Crystal Display (LCD) and the pcb board, even there is very little displacement all can the normal demonstration of Liquid Crystal Display (LCD) to be exerted an influence.And feet 2 bottoms turn round pawl 3 in when twisting, metal framework can be pullled Liquid Crystal Display (LCD) and make its distortion, and causes and influence the displacement of Liquid Crystal Display (LCD) and zebra bar the zebra bar and dock with the correct of Liquid Crystal Display (LCD).To turn round pawl and reverse the influence that Liquid Crystal Display (LCD) is produced in order to reduce, the pawl of turning round on the feet is preferably the symmetrically arranged two-way pawl of turning round, and when reversing pawl, two-way torsion can be cancelled out each other, thereby reduces the pull power of metal frame to Liquid Crystal Display (LCD).
For fear of tests such as ESD, to the harmful effect that Liquid Crystal Display (LCD) brings, pcb board can with turn round the part that pawl offsets and copper facing be set, the ground conductive of copper facing and pcb board.
Scratch copper facing when turning round pawl and reverse, can bevelling or fillet be set turning round the contacted side of pawl and pcb board copper facing part.
