As shown in fig. 2, the display screen module of the present invention includes a frame made of plastic, a backlight plate 2, TFTs, an upper frame 1, and the like. The frame is generally rectangular, as is the case with the conventional frame. The upper iron frame 1 is buckled with the rubber iron frame and fixedly connected with the rubber iron frame, and a rectangular box for placing the backlight plate 2, the TFT and the like is enclosed by the upper iron frame 1 and the rubber iron frame. The periphery of the backlight plate 2 is provided with a convex flange 21, and the middle part is provided with a groove for arranging TFTs and the like. And the side of the flange 21 is provided with a protruding catch 22.

Go up sidewall 12 of iron frame 1 and be equipped with draw-in groove 13 and shell fragment 14, draw-in groove 13 is formed by the trompil of seting up at last iron frame 1 sidewall 12, and shell fragment 14 is located draw-in groove 13 lower extreme and adjacent with draw-in groove 13, and wherein the lower extreme of draw-in groove 13 is close to the one end of glued metal frame promptly, and shell fragment 14 is adjacent with draw-in groove 13 promptly and the lower extreme next-door neighbour shell fragment 14 of draw-in groove 13, does not go up iron frame 1 sidewall 12 separation between shell fragment 14 and the draw-in groove 13. The elastic piece 14 includes an inclined wall 141 and a parallel wall 142, the inclined wall 141 has a lower end connected to the side wall 12 of the upper iron frame 1 and a top end extending obliquely toward the inside of the upper iron frame 1, and the parallel wall 142 has a lower end connected to the inclined wall 141 and extending parallel to the side wall 12 of the upper iron frame 1. When the spring 14 is in a free state, i.e. the upper iron frame 1 and the backlight panel 2 are not assembled together, the parallel wall 142 of the spring 14 extends to the assembling area of the backlight panel 2.

When assembling the display screen module, firstly the backlight plate 2, the TFT and the like are assembled in the rubber frame, and then the upper iron frame 1 is buckled and fixed on the rubber frame. When installing iron stand 1, earlier align last iron stand 1 with the chimb 21 of board 2 in a poor light, then move upward iron stand 1 to the glued iron frame direction, at the in-process of moving upward iron stand 1, the card ear 22 of board 2 in a poor light passes through shell fragment 14 earlier, makes shell fragment 14 produce deformation under the extrusion of card ear 22, until the card ear 22 of board 2 in a poor light gets into draw-in groove 13, the deformation of shell fragment 14 reduces, parallel wall 142 with zero clearance or the mode butt of interference on the side that lies in card ear 22 lower extreme of chimb 21.

In the display screen module, the upper iron frame 1 and the backlight plate 2 are fixed through the clamping lugs 22 and the clamping grooves 13 and are also fixed in an auxiliary mode through the elastic sheets 14. Since the elastic sheet 14 can be largely deformed, the elastic sheet 14 can be designed to have a large inclination. Like this, even go up iron stand 1 supplied materials great or the board 2 supplied materials are less, when making and go up to produce the clearance between iron stand 1 and the board 2 in a poor light, also can block board 2 in a poor light by shell fragment 14, avoid going up iron stand 1 and board 2 in a poor light and appear the not hard up problem of cooperation to avoid appearing rocking the hidden danger of influence, especially when being applied to the on-vehicle display product with this display screen module, can improve user experience greatly.

The dimension of the parallel wall 142 of the elastic sheet 14 protruding from the side wall 12 of the upper iron stand 1 may be equal to or slightly larger than the maximum error between the backlight panel 2 and the upper iron stand 1. For example, when the maximum error between the backlight panel 2 and the upper iron stand 1 is 0.2mm, the size of the parallel wall 142 of the elastic piece 14 protruding from the side wall 12 of the upper iron stand 1 may be 0.2mm, or 0.25mm, for example. In a preferred example, the tolerance between the parallel walls 142 of the spring 14 and the side of the convex edge 21 of the backlight 2 is 0-0.2mm, i.e. the maximum dimension of the parallel walls 142 of the spring 14 pressed by the convex edge 21 of the backlight 2 is 0.2 mm. So set up, under the prerequisite of guaranteeing elasticity and life of shell fragment 14, improve the cooperation fastness between board 2 in a poor light and the last iron stand 1 as far as possible.

Furthermore, a plurality of slots 13 and spring pieces 14 corresponding to the slots 13 may be arranged at intervals along the circumferential direction of the side wall 12 of the upper iron frame 1, each slot 13 is respectively provided with a clamping lug 22, and the size and the structure of each spring piece 14 are the same. In one example, the length L of the spring 14 is 0.5-2mm, wherein the length L of the spring 14 is a dimension parallel to the side wall 12 of the upper iron frame 1. The ratio of the lengths of the inclined wall 141 and the parallel wall 142 of the spring 14 is 2-3:1, wherein the lengths of the inclined wall 141 and the parallel wall 142 are the dimension parallel to the direction of the side wall 12 of the upper iron frame 1. In a preferred example, when the length of the spring 14 is longer, for example 2mm, the ratio of the lengths of the inclined wall 141 and the parallel wall 142 of the spring 14 is 2:1, i.e. the longer the spring 14 is, the longer the parallel wall 142 of the spring 14 is; when the length of the spring 14 is short, for example 0.5mm, the ratio of the lengths of the inclined wall 141 and the parallel wall 142 of the spring 14 is 3:1, i.e. the shorter the spring 14 is, the shorter the parallel wall 142 of the spring 14 is.

The parallel wall 142 of the spring plate 14 does not fully protrude from the side wall 12 of the upper iron stand 1 in a direction perpendicular to the side wall 12 of the upper iron stand 1. In one example, the overlapping dimension of the parallel wall 142 of the spring 14 and the side wall 12 of the upper hob 1 is smaller than the non-overlapping dimension of the parallel wall 142 and the side wall 12 of the upper hob 1. Set up shell fragment 14 through above-mentioned mode, can be under the prerequisite of further guaranteeing the elasticity of shell fragment 14 and life, improve the cooperation fastness between board 2 in a poor light and the last iron stand 1 as far as possible, improve user experience greatly.

In addition, along the side wall 12 direction of the upper iron frame 1, a gap is left between the parallel wall 142 of the spring piece 14 and the clamping lug 22 of the backlight plate 2, namely, the parallel wall 142 of the spring piece 14 is not abutted against the lower end surface of the clamping lug 22 of the backlight plate 2. In one example, along the direction of the side wall 12 of the upper iron frame 1, the gap between the parallel wall 142 of the elastic piece 14 and the lug 22 of the backlight plate 2 is greater than 0.5mm, that is, the distance between the upper end of the elastic piece 14 and the top surface 11 of the upper iron frame 1 is 0.5mm on the basis of the maximum processing distance between the upper surface of the convex edge 21 of the backlight plate 2 and the lower end surface of the lug 22, so as to avoid interference between the elastic piece 14 and the lug 22 and between the top surface 11 of the upper iron frame 1 and the upper surface of the convex edge 21 of the backlight plate 2, in other words, to avoid the backlight plate 2 being installed in place, but the parallel wall 142 of the elastic piece 14 is clamped on the lug 22.

Furthermore, the ratio of the thickness of the side wall 12 of the upper iron frame 1 to the overlapping size of the clamping lug 22 and the side wall 12 of the upper iron frame 1 is 1.5-2:1 in the direction vertical to the side wall 12 of the upper iron frame 1, namely, the depth of the clamping lug 22 clamped in the clamping groove 13 is not more than 2/3 of the thickness of the side wall 12 of the upper iron frame 1 in the direction vertical to the side wall 12 of the upper iron frame 1. The clamping lug 22 of the backlight plate 2 is an inclined surface 221 at one side facing the top surface 11 of the iron stand 1, and the inclination degree of the inclined surface 221 of the clamping lug 22 is smaller than that of the inclined wall 141 of the elastic sheet 14. So set up, can make card ear 22 of board 2 in a poor light pass through shell fragment 14 smoothly and the card establishes in draw-in groove 13, when card ear 22 passes through shell fragment 14 moreover, reduce the damage to shell fragment 14, improve the life of shell fragment 14.

While the present invention has been described with reference to the embodiments shown in the drawings, the present invention is not limited to the embodiments, which are illustrative and not restrictive, and it will be apparent to those skilled in the art that various changes and modifications can be made therein without departing from the spirit and scope of the utility model as defined in the appended claims.
