Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more apparent, the technical solutions of the present invention will be clearly and completely described below with reference to the specific embodiments of the present invention and the accompanying drawings. It is to be understood that the described embodiments are merely exemplary of the utility model, and not restrictive of the full scope of the utility model. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
As shown in fig. 1 and 2, the display module of the present invention includes a frame made of plastic, an upper frame 1, a backlight plate 2, a TFT4, and a foam 3. The rubber frame and the upper iron frame 1 are buckled to form a cuboid box to form a supporting frame of the display module. The backlight plate 2 is cuboid, the middle part of the top surface is provided with an inward concave groove, and a convex flange 21 is formed around the groove. The backlight plate 2 is arranged in the shape of a plastic frame, and the convex edge 21 protrudes out of the plastic frame and extends to the upper iron frame 1. And the side of the backlight plate 2 is provided with a convex clamping lug 22, the side wall 12 of the upper iron frame 1 is provided with a clamping groove 13, and the clamping lug 22 of the backlight plate 2 is clamped in the clamping groove 13. The foam 3 is abutted between the top wall 11 of the upper iron frame 1 and the top surface of the convex edge 21 of the backlight plate 2.
In the display module, the fixing of the upper iron frame 1 and the backlight plate 2 in all directions is realized by the matching of the clamping lugs 22 and the clamping grooves 13 and the foam 3. Like this, even go up iron stand 1 big on the side or the board 2 in a poor light is on the side little and make and leave the clearance between 1 lateral wall 12 of iron stand and the board 2 chimb 21 side in a poor light, also can avoid going up the not hard up problem of cooperation appearing between iron stand 1 and the board 2 in a poor light, avoid display module to appear rocking the hidden danger of abnormal sound, improve display module's equipment fastness.
A foam 3 may be disposed between the upper iron frame 1 and the backlight plate 2, and the foam 3 is disposed on a convex edge 21 at one end of the backlight plate 2, for example, the foam 3 is disposed on the convex edge 21 at one side of the short side of the backlight plate 2. And the backlight plate 2 is provided with a containing groove 23 at the position where the foam 3 is arranged, and the foam 3 is placed in the containing groove 23. So set up, the interval between chimb 21 and the last iron stand 1 that makes 2 other positions in a poor light is less, makes 2 in a poor light be on a parallel with the setting of glued membrane frame diapire in the glued membrane frame, reduces 2 oblique risks in a poor light.
Furthermore, the height of the foam 3 protruding out of the backlight plate 2 is preferably 0.2-0.4 mm. The cooperation error that combines 1 roof 11 of iron stand and 2 chimbs 21 upper surface in a poor light board in the design during this height makes the cotton 3 last iron stand 1 and the board 2 in a poor light that is suitable for used size basically of bubble, reduces the installation moreover and steeps cotton 3 back board 2 slope risks.
The width of the foam 3 can be 1-2mm smaller than the width of the corresponding side convex edge 21 of the backlight plate 2. And along the direction perpendicular to the convex edge 21 of the corresponding side of the backlight plate 2, the two sides of the accommodating groove 23 respectively penetrate through the convex edge 21 of the corresponding side of the backlight plate 2. And the length of the containing groove 23 is less than the length of the convex edge 21 of the corresponding side of the backlight plate 2, so that the two ends of the containing groove 23 do not penetrate through the convex edge 21 of the corresponding side of the backlight plate 2, namely, the two ends of the containing groove 23 are provided with groove walls. The length of the foam 3 is greater than that of the accommodating groove 23, so that two ends of the foam 3 are clamped in the accommodating groove 23. Before assembling the backlight plate 2, the foam 3 is placed into the substantially middle position of the accommodating groove 23 from one side of the accommodating groove 23, and the two ends of the foam 3 are clamped in the accommodating groove 23. Due to the arrangement, the flatness is high when the foam 3 is placed in the accommodating groove 23, and the inclination risk of the backlight plate 2 after the foam 3 is installed is reduced; simple structure and convenient processing and manufacturing.
In addition, along the circumference of the top wall 11 of the upper iron frame 1, a plurality of clamping grooves 13 are arranged on the side wall 12 of the upper iron frame 1 at intervals, a plurality of clamping lugs 22 are arranged on the side surface of the backlight plate 2 at intervals, and each clamping lug 22 is clamped in one clamping groove 13. And the distance between the clamping lug 22 and the top wall 11 of the upper iron frame 1 is larger than the distance between the clamping lug 22 and the bottom wall of the upper iron frame 1. So set up to further improve the equipment fastness of going up iron stand 1 and board 2 in a poor light, reduce to set up and steep cotton 3 back board 2 emergence slope risk.
The vehicle-mounted display device comprises the display module. In the vehicle-mounted display device, the upper iron frame 1 and the backlight plate 2 are fixed in all directions by the matching of the clamping lugs 22 and the clamping grooves 13 and the foam 3. Like this, even go up iron stand 1 big on the side or the board 2 in a poor light is on the side little and make and leave the clearance between 1 lateral wall 12 of iron stand and the board 2 chimb 21 side in a poor light, also can avoid going up the not hard up problem of cooperation appearing between iron stand 1 and the board 2 in a poor light, avoid display module to appear rocking the hidden danger of abnormal sound, improve display module's equipment fastness.
The vehicle-mounted display device can be a central control screen or an instrument screen, and can also be a display screen key and the like.
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.
