Structure, the vehicle-mounted liquid crystal module include glue frame, light guide plate, reflectance coating and lower chase, wherein, the glue frame, the light guide plate and institute
State reflectance coating be sequentially overlapped set and be assemblied in the lower chase, the light guide plate including a LED enter plain edge and three it is non-enter light
Side, it is each it is described it is non-enter plain edge stretch out formed with two boss, the glue frame is concavely provided with the position of the corresponding boss
One-to-one avoiding hollow groove, the reflectance coating stretch out formed with the one-to-one catch of the boss.
Preferably, the reflectance coating correspond to it is described it is non-enter plain edge side be bent to form gear towards the light guide plate
Wall, and the retaining wall sets one-to-one empty avoiding breach in the position of the corresponding catch, the retaining wall is attached to corresponding
It is described it is non-enter plain edge side wall on.
Preferably, the width of the boss and length are respectively less than the avoiding hollow groove corresponding to it.
Preferably, the length and width of the catch with its corresponding to the avoiding hollow groove match.
Technical solutions of the utility model are pushed down by using the avoiding hollow groove in glue frame on boss and reflectance coating on light guide plate
Catch, then be assembled together with lower chase, so that light guide plate and transmitting film will not be because of contraction and loose in extreme circumstances
It is dynamic to come off, service life is influenceed, by redesigning light guide plate, reflectance coating and glue frame assembling structure, improves vehicle-mounted liquid crystal module
The durability of extreme environment is applicable, postpones the backlight module life-span, saves the energy.
Brief description of the drawings
, below will be to embodiment in order to illustrate more clearly of the utility model embodiment or technical scheme of the prior art
Or the required accompanying drawing used is briefly described in description of the prior art, it should be apparent that, drawings in the following description are only
It is some embodiments of the utility model, for those of ordinary skill in the art, is not paying the premise of creative work
Under, other accompanying drawings can also be obtained according to the structure shown in these accompanying drawings.
Fig. 1 is structural representation of the present utility model；
Fig. 2 is Fig. 1 explosive view；
Fig. 3 is the connection diagram of avoiding hollow groove, boss and catch in the utility model；
Fig. 4 is the connection diagram of boss and catch in the utility model；
Realization, functional characteristics and the advantage of the utility model purpose will be described further referring to the drawings in conjunction with the embodiments.
Embodiment
The utility model proposes the assembling structure that a kind of vehicle-mounted liquid crystal module is applicable extreme environment.
In the utility model embodiment, the assembling structure；As shown in Figures 1 to 4, vehicle-mounted liquid crystal module includes glue frame
10th, light guide plate 20, reflectance coating 30 and lower chase 40, wherein, glue frame 10, light guide plate 20 and reflectance coating 30, which are sequentially overlapped, to be set and fills
Fit in lower chase 40, light guide plate 20 including a LED enter plain edge 210 and three it is non-enter plain edge 220, it is each it is non-enter plain edge 220 it is outside
Extension is concavely provided with one-to-one avoiding hollow groove 110 in the position of corresponding boss 230, reflected formed with two boss 230, glue frame 10
Film 30 stretches out formed with catch 310 one-to-one with boss 230.
Technical solutions of the utility model push down the boss 230 on light guide plate 20 by using the avoiding hollow groove 110 in glue frame 10
With the catch 310 on reflectance coating 30, then it is assembled together with lower chase 40, so that light guide plate 20 and transmitting in extreme circumstances
Film loose or dislocation, light guide plate 20 will not arbitrarily be expanded because of contraction, and glue frame 10 is arbitrarily shunk, and both of which was not interfered with using the longevity
Life, by redesigning light guide plate 20, reflectance coating 30 and the assembling structure of glue frame 10, improves vehicle-mounted liquid crystal module durability, postpones
In the backlight module life-span, save the energy.
Preferably, reflectance coating 30 it is corresponding it is non-enter plain edge 220 side be bent to form retaining wall 320 towards light guide plate 20, and keep off
Wall 320 sets one-to-one empty avoiding breach 330 in the position of corresponding catch 310, retaining wall 320 be attached to corresponding to it is non-enter plain edge
In 220 side wall.Because glue frame 10 is black, black light-absorbing is avoided to have an impact light guide plate 20, so using white reflection film
The side wall of 30 light guide plates 20 is also wrapped simultaneously, while prevents bending from rebounding for reflectance coating 30, the pre- broken string of bending part increase.
Preferably, the width of boss 230 and length are respectively less than the avoiding hollow groove 110 corresponding to it.After assembling, avoiding hollow groove
110 notched joint touches down chase, avoids light guide plate 20 from being contacted with lower chase 40, it is also had certain expansion space.
Preferably, the length and width of catch 310 with its corresponding to avoiding hollow groove 110 match.Because boss 230
Length and width are both less than the avoiding hollow groove 110 corresponding to it, thus the length and width of catch 310 matched with avoiding hollow groove 110 can just block completely it is convex
Platform 230, avoid its light leak.
During assembling, light guide plate 20 puts into the inside of reflectance coating 30 for being provided with retaining wall 320, and retaining wall 320 is attached into light guide plate 20
Side, then put lower chase 40 into, glue frame 10 is entered along the lower checkpost of chase 40 4, and the top surface of avoiding hollow groove 110 is pressed in light guide plate 20
Rectangle boss 230 on.The catch 310 that so reflectance coating 30 stretches out withstands lower chase 40, cannot be loosened after.In height
The extreme environment of warm low temperature or thermal shock, light guide plate 20 are arbitrarily expanded, and glue frame 40 is arbitrarily shunk, and both of which is not interfered.
Preferred embodiment of the present utility model is the foregoing is only, not thereby limits the scope of the claims of the present utility model,
Every equivalent structure change under inventive concept of the present utility model, made using the utility model specification and accompanying drawing content
Change, or directly/be used in other related technical areas indirectly and be included in scope of patent protection of the present utility model.
