Description

Liquid crystal screen fixing device of motorcycle instrument

Technical Field

The utility model relates to a screen fixing technology field, concretely relates to LCD screen fixing device of motorcycle instrument.

Background

All motor vehicles are provided with the instrument boxes in the direction of the vehicle head and used as the operation display of the motor vehicle electronic control system, so that a driver can more intuitively obtain the feedback of the operation of the driver, and the instrument boxes are one of necessary accessories of all motor vehicles. In order to ensure that the instrument can be stably used for a long time, the fixation of the liquid crystal screen of the instrument is particularly important. The common fixing method of the liquid crystal screen is clamping fixing, but deformation is easily formed at the clamping pressing position after long-term use, and particularly, the bottom color of the instrument display screen of the motor vehicle is mostly black, and liquid leakage or white spots are easily generated. Therefore, a new fixing device for LCD screen is needed.

SUMMERY OF THE UTILITY MODEL

The utility model discloses aim at solving the technical problem who exists among the prior art at least, innovate the LCD screen fixing device who provides a motorcycle instrument very much, can follow the fixed LCD screen in back, side, it is fixed stable to can not produce weeping or white point.

In order to achieve the above object of the present invention, the present invention provides a liquid crystal screen fixing device for motorcycle instruments, comprising a housing composed of a front cover plate and a rear housing with a frame structure having a front opening, wherein the front cover plate is fastened to the opening side of the rear housing, a display window is provided on the front cover plate corresponding to the display area of the liquid crystal screen, a screen fixing bracket is provided in the rear housing, the screen fixing bracket is a groove structure having a front opening, the liquid crystal screen is covered on the notch of the screen fixing bracket, a surrounding edge for surrounding the liquid crystal screen is provided outside the notch, a back glue for adhering the liquid crystal screen is provided on the notch of the screen fixing bracket, a circle of elastic piece abdicating notch is provided around the liquid crystal screen, elastic pieces for supporting the side edge of the liquid crystal screen are provided in the abdicating notch, the elastic pieces are integrally formed with the screen fixing bracket, and a circle of damping sponge is arranged on the back surface of the front cover plate around the display window.

The window that sets up is used for exposing the display area of LCD screen, and the screen fixed bolster that sets up is used for fixed LCD screen, and the shell fragment that sets up is used for fixed LCD screen all around, presss from both sides the plate body of LCD screen through the shell fragment, can not push down the liquid crystal of LCD screen, prevents to produce the white point on the LCD screen. The shock attenuation sponge that sets up is used for propping the LCD screen openly, avoids the LCD screen openly and front shroud striking.

In the scheme, the method comprises the following steps: the bottom of the screen fixing support is provided with a plurality of irregular supporting ribs for supporting the liquid crystal screen. The support ribs form a hollow shape, so that heat dissipation is facilitated, and the situation that the back glue is degummed or the screen fixing support is deformed due to overhigh display temperature of the liquid crystal screen is avoided.

In the scheme, the method comprises the following steps: the thickness of the back adhesive is 0.5 mm-3 mm.

The back glue can fix the outer edge of the back of the liquid crystal screen, and the connection stability of the outer edge of the back of the liquid crystal screen is improved. The support ribs can support the middle of the back of the liquid crystal screen. The thickness of gum sets up to 0.5mm ~ 3mm, can the shock attenuation, reduces the abnormal sound as far as possible.

In the scheme, the method comprises the following steps: and two elastic sheets are arranged on the surrounding edges of the four sides of the screen fixing support.

In the scheme, the method comprises the following steps: two shell fragments that lie in the downside all set up along the vertical central line bilateral symmetry of screen fixed bolster, and the spacing distance of the shell fragment of upside is less than the spacing distance between the shell fragment of downside. The elastic sheets on the upper side and the lower side are arranged in a left-right staggered mode, so that the clamping points on the upper side and the lower side are prevented from being located on the same straight line, the clamping points are dispersed, and the clamping stability is improved. Meanwhile, the liquid crystal display screen is normally arranged to be a transverse screen, the upper width and the lower width are smaller than the left width and the right width, the situation that the liquid crystal display screen is deformed due to the fact that the upper clamping force and the lower clamping force are overlapped can be avoided, and conventional requirements are met.

In the scheme, the method comprises the following steps: two shell fragments that lie in left and right sides all set up along screen fixed bolster's horizontal central line bilateral symmetry. The stress is symmetrical, and the stability is improved.

To sum up, owing to adopted above-mentioned technical scheme, the beneficial effects of the utility model are that: the installation is simple, and is fixed reliable, fixes the back, the side of LCD screen simultaneously, can not produce the removal, and is stable high-efficient. The gum that sets up can effectively fix the back of LCD screen, and the shell fragment of setting can retrain around LCD screen to in the display area who can not touch LCD screen, can not produce the condition of deformation, extrusion liquid level or weeping. The shock attenuation sponge that sets up can prevent effectively that the front shroud from to the extrusion of LCD screen, further avoids producing the condition that extrudees the liquid level, produce deformation in LCD screen's front.

Additional aspects and advantages of the invention will be set forth in part in the description which follows and, in part, will be obvious from the description, or may be learned by practice of the invention.
