Abstract

The invention discloses an automobile meter liquid crystal display and relates to the field of automobile processing. An installing base (2) is designed into a concave structure as a whole. Four sides of the upper end of the installing base are extended upward to form a buckling side. Edges of two sides of the buckling side are extended perpendicularly outward into an edge. A buckling hook (3) is fixed at the front end and the back end inside the base (2) and designed into an inverted-L-shaped structure. An elastic piece (4) is installed at one end inside the base (2) and the sides of the buckling hook (3). A limit rib (5) is arranged at two sides of the buckling side. An elastic bearing (6) is installed at two sides of a concave surface inside the base (2). Due to the fact that the tongue-shaped elastic structure is matched with the inverted-L-shaped buckling hook, the an automobile meter liquid crystal display is capable of achieving fast installing and positioning of the liquid crystal display (LCD), greatly improving efficiency of production and assembling, avoiding damage to the whole mechanism even under the condition of repeat assembling and disassembling, and enabling the display to provide effectively fixing and protection under the harsh using environment of bumping roads and the like.

Description

A kind of LCD of automobile instrument

Technical field:

The present invention relates to automobile processing and manufacturing field, be specifically related to a kind of LCD of automobile instrument.

Background technology:

Traditional fixed form mostly is the ordinary construction shown in the accompanying drawing 1, and this snap fit need to rely on when LCD is installed and LCD is applied downward pressure push snap fit open along the guiding surface of snap fit, LCD is installed into rear snap fit resilience block LCD.Because the glass material of LCD has very sharp cutting edge at the edge, the surface of plastics snap fit can be wiped off one deck plastics chip in the time of installation.If the risk of the excessive display of crushing in addition of installing force.And the situation that the easy fracture of this snap fit lost efficacy, holding force also can be lost thereupon, causes LCD to come off or circuit connection inefficacy.

Summary of the invention:

The purpose of this invention is to provide a kind of LCD of automobile instrument, it can solve the installation of existing automobile instrument LCD screen and fixed sturcture assembling inconvenience in the background technology, poor reliability, the problem that easily lost efficacy effectively.

In order to solve the existing problem of background technology, the present invention by the following technical solutions: it comprises mounting seat 2, snap fit 3, shell fragment 4, limit rib 5 and elastic force supporting 6; Mounting seat 2 integral body are concave structure, the four edges of its upper end extends upward edge, the edge of edge both sides outwards vertically extends an edge, snap fit 3 is fixed on the rear and front end in the base 2, it is whole to be the shape of falling L structure, and shell fragment 4 is installed in the end in the base 2, and is positioned at the side of snap fit 3, limit rib 5 is arranged on the both sides of edge, and elastic force supporting 6 is installed in the both sides on mounting seat 2 concave shaped planes.

Described shell fragment 4 is the shell fragment of ligulate.

The present invention has following beneficial effect: by the elastic piece structure that the adopts ligulate way that matches with the inverted L-shaped snap fit; realize that LCD installs and locate purpose fast; improved greatly the efficient of producing and assembling; even repeated disassembled and assembled also can not produce damage to whole mechanism, and satisfy display and under road such as jolts at the abominable environment for use, still can provide effectively fixing and protection.

Embodiment:

Referring to Fig. 2-3, this embodiment is by the following technical solutions: it comprises mounting seat 2, snap fit 3, shell fragment 4, limit rib 5 and elastic force supporting 6; Mounting seat 2 integral body are concave structure, the four edges of its upper end extends upward edge, the edge of edge both sides outwards vertically extends an edge, snap fit 3 is fixed on the rear and front end in the base 2, it is whole to be the shape of falling L structure, and shell fragment 4 is installed in the end in the base 2, and is positioned at the side of snap fit 3, limit rib 5 is arranged on the both sides of edge, and elastic force supporting 6 is installed in the both sides on mounting seat 2 concave shaped planes.

Described shell fragment 4 is the shell fragment of ligulate.

Referring to Fig. 4-5, installation method to this embodiment is further elaborated: first LCD screen 1 is inserted the end that shell fragment 4 is arranged in the mounting seat 2, setting level LCD shields 1 rear direction toward shell fragment 4 and pushes away LCD screen 1, because shell fragment 4 has elasticity can be compressed, and have the gap between snap fit 3 and the LCD screen 1, so LCD screen 1 can (referring to Fig. 4) is pushed a segment distance along the direction of arrow.And then LCD shields the edge that 1 side that is pushed away can be crossed snap fit 3, thereby make on the LCD screen 1 spill platform that falls into thoroughly on the mounting seat 2, as long as at this moment cancel the thrust to LCD screen 1, under the rebound effect power of shell fragment 4, LCD screen 1 will be along the track that pushes toward the resilience of (referring to Fig. 5) direction of arrow, thereby LCD is shielded in the bayonet socket that 1 integral body enters down snap fit 3, thereby finish installation.

Apply certain snap-in force in order to make shell fragment 4 shield 1 to LCD, need to when making, allow the position of shell fragment 4 after stress not and assembling leave certain magnitude of interference, and the screen of the LCD after assembling 1 is realized effectively fixing under the effect of limit rib 5 in X-direction, shell fragment 4 and snap fit 3 make LCD screen 1 realize effectively spacing in Y-axis, and cooperatively interacting between elastic force supporting 6 and the snap fit 3, LCD screen 1 is obtained effectively effectively fixing in Z-direction, and elastic force supporting 6 can be played certain buffer action when LCD screen 1 is subject to huge impact, and can eliminate the abnormal sound that causes because of the fit-up gap.

This embodiment has following beneficial effect: by the elastic piece structure that the adopts ligulate way that matches with the inverted L-shaped snap fit; realize that LCD installs and locate purpose fast; improved greatly the efficient of producing and assembling; even repeated disassembled and assembled also can not produce damage to whole mechanism, and satisfy display and under road such as jolts at the abominable environment for use, still can provide effectively fixing and protection.

Drawings and Examples described herein are only in order to illustrate that technical scheme of the present invention is not intended to limit; Although with reference to preferred embodiment the present invention has been carried out more detailed explanation, those of ordinary skill in the field are to be understood that; Still can make amendment or the part technical characterictic is equal to replacement the specific embodiment of the present invention; And not breaking away from the spirit of technical solution of the present invention, it all should be encompassed in the middle of the technical scheme scope that the present invention asks for protection.
