[0031] Example

[0032] Generally, the LCD screen 3 is placed in the housing 1, and the LCD screen 3 needs to be fixed to the housing 1 by four screws, and then the rear cover 2 is fixed to the housing 1 by four screws. However, this method leads to low assembly efficiency and cannot meet the production requirements of the LCD module assembly production line.

[0033] To do this, see Figure 1-5 The utility model provides an anti-falling LCD module, comprising:

[0034] The shell 1 has an LCD display screen 3 movably mounted in the inner concave cavity of the shell 1, and an FPC cable 31 is electrically connected to the LCD display screen 3. The front side of the shell 1 is provided with a through opening adapted to allow the front display end of the LCD display screen 3 to pass through. A rear end cover 2 is movably mounted at the rear opening of the shell 1. The rear side of the shell 1 is also provided with a notch movably matched with the FPC, and the rear end cover 2 is also connected to the shell 1 through a clamping component 4 and a tightening component 6, respectively.

[0035] Further Figure 3 As shown, it is worth explaining in detail that in order to compress and fix the FPC cable 31 to prevent shaking and falling off, a rubber sealing strip 5 is movably installed in the gap, and the rubber sealing strip 5 is fixed on the rear end cover 2. The length of the rubber sealing strip 5 is equal to the length of the gap.

[0036] Among them, in the third effect of the beneficial effects, the external moving body refers to, for example, a car, such as an LCD module on a car. The FPC cable 31 can be pressed and fixed by the rubber sealing strip 5 to avoid shaking when the car moves, thereby greatly reducing the possibility of the FPC cable 31 falling off the LCD display screen 3.

[0037] Further as Figure 3-4 As shown, it is worth specifically explaining that, in order to facilitate the fixing of the rear end cover 2 on the housing 1, a clamping assembly 4 is provided, including pressing rods 41 movably provided on both sides of the rear end cover 2, two symmetrically provided push columns 42 are fixedly connected to the side walls opposite to the two pressing rods 41, and the bottom end of the rear end cover 2 is slidably connected with L-shaped clamping blocks 45 all around, and the top of the L-shaped clamping blocks 45 is fixedly provided with sliders a43 with an inverted "convex" structure in vertical section, and the sliders a43 are slidably connected to the bottom end of the rear end cover 2. In the slide groove a, one end of the push column 42 away from the pressing rod 41 is movably inserted into the slide groove a on the corresponding side and is connected to one end of the slider a43. The end of the slider a43 away from the push column 42 is connected to the inner wall of the slide groove a through a spring a44. Two symmetrically arranged bayonet holes 451 are penetrated on the two side walls of the shell 1, and the bayonet holes 451 are engaged with the corresponding L-shaped blocks 45. The two pressing rods 41 are threaded with hand screws, and the locking ends of the hand screws are pressed against the outer side of the rear end cover 2.

[0038] Among them, the setting of the hand screw is to prevent external force from arbitrarily pressing the two pressing rods 41 and causing the L-shaped block 45 to disengage from the bayonet 451. Of course, when removing the rear end cover 2, it is necessary to loosen the two hand screws, which makes it easier to press the two pressing rods 41 towards each other, so as to realize the removal of the rear end cover 2 from the outer shell 1.

[0039] Further as Figure 4-5 As shown, it is worth specifically explaining that, in order to enable the LCD liquid crystal display screen 3 to be synchronously clamped and fixed in the inner cavity of the shell 1 when the rear end cover 2 is fixed on the shell 1, a clamping assembly 6 is provided, including L-shaped clamping blocks 61 that are slidably connected around the inner wall of the concave cavity of the shell 1, and the four L-shaped clamping blocks 61 are used to clamp the four corners of the LCD liquid crystal display screen 3 respectively, and the end of the L-shaped clamping block 61 away from the rear end cover 2 is fixedly connected to a slider b64 with a convex structure in a vertical cross-section, and the slider b64 is slidably connected to the slide groove b provided on the inner wall of the concave cavity of the shell 1, and the end of the slider b64 facing the through-hole is connected to the inner wall of the slide groove b through a spring b65, and the end of the L-shaped clamping block 61 away from the slider b64 is provided with an inclined surface a62, and the side wall of the rear end cover 2 facing the shell 1 is fixedly connected with a pressing block 63, and the end of the pressing block 63 away from the rear end cover 2 is provided with an inclined surface b631 matching the inclined surface a62.

[0040] When the inclined surface b631 of the pressing block 63 moves downward, it can squeeze the L-shaped pressing block 61 of the inclined surface a62, thereby causing the four L-shaped pressing blocks 61 to move toward the through-opening direction, thereby facilitating the clamping and fixing of the four corners of the LCD display screen 3. At the same time, the spring b65 is in a compressed state in the attached figure.

[0041] In summary, when assembling the anti-drop LCD module, first put the LCD screen 3 into the concave cavity, and the front display surface of the LCD screen 3 passes through the through opening. Then, loosen the two hand screws and press the two pressing rods 41 to move relative to each other, so that the push columns 42 press the slider a43, so that the slider a43 presses and deforms the spring a44, and the L-shaped blocks 45 move toward the middle of the rear cover 2. At this time, the rear cover 2 is covered on the housing 1. After closing the cover, release the two pressing rods 41, so that the L-shaped clamping blocks 45 are all clamped into the corresponding clamping holes 451, thereby realizing the assembly between the rear end cover 2 and the shell 1. During this process, when the inclined surfaces b631 of the four pressing blocks 63 move downward, they can squeeze the L-shaped clamping blocks 61 of the inclined surfaces a62, thereby making the four L-shaped clamping blocks 61 move toward the through-opening, thereby facilitating the synchronous clamping and fixing of the four corners of the LCD display screen 3, greatly improving the efficiency of assembly, and having a good practical effect.
