Problems solved by technology

The back cover of the existing display device often adopts two methods for fixing: one is the screw fixing method, that is to say, the back cover is fixed on the back of the backlight module by screws. Although this assembly is stable and reliable, it will affect the display. The overall aesthetics of the back of the device, the position between the screws is prone to gaps, resulting in light leakage and increasing the possibility of foreign objects entering the display device in the use environment. At present, most display devices in public places in the market are surrounded by the screen display area of ​​the display device. There are different degrees of dark spots; the second is the glue or tape fixing method. This method does not have the function of bad heavy industry repair during production. The fixation is completed, and the glue or tape is sensitive to the temperature and humidity of the environment. As time goes by, it is easy to have the defect that the back cover and the backlight module are separated due to the adhesive failure of the glue or tape, which seriously affects the reliability of the display device.

Embodiment 1

[0045] This embodiment provides a display device.

[0046] Please refer to Figure 1-2 , the display device includes a backlight module A, a rear case and a rear case fixing structure B.

[0047] Wherein, the rear case fixing structure B is installed on the back of the backlight module A, and the rear case fixing structure B has a first engaging portion 200, the rear case is detachably installed on the rear case fixing structure B, and the inner surface of the rear case There is a second engaging portion C that can be fastened with the first engaging portion 200, so that when the rear case is installed on the rear case fixing structure B, the first engaging portion 200 and the second engaging portion C both Being located on the inner surface of the rear case and being hidden by the rear case can greatly improve the aesthetics of the back of the display device.

[0048] According to the embodiment of the present invention, the specific type of the display device is not limite...

Embodiment 2

[0079] The principle and basic structure of the second embodiment are generally the same as those of the first embodiment, the difference is that the second embodiment provides another specific fastening method, and at the same time, the second embodiment also provides another guide transition mechanism 400 .

[0080] Specifically, first combine the reference Figure 7-12 , in the second embodiment, the first engaging portion 200 is a lock hole directly formed on the mobile frame 100, and the lock hole is composed of at least two sections, one of which has a smaller diameter and the other has a larger diameter. The locking hole is formed with at least a large end 220 and a small end 230 . When the second buckle part is separated from the lock hole, the second buckle part C fits at the big end 220 (such as Figure 9-10 shown), and when the mobile frame 100 moves, the second buckle part C will move from the large end 220 to the small end 230 (such as Figure 11-12 As shown), ...

Abstract

The invention discloses a rear shell fixing structure and a display device. The rear shell fixing structure includes a moving frame, a first engaging part and a driving mechanism. The moving frame is arranged movably, and the moving frame can reciprocate in at least one direction. movement, the first engaging part is installed on the moving frame, the moving frame is installed on the output end of the driving mechanism, and the driving mechanism is used to drive the moving frame to move, so that the first card The engaging portion is engaged or separated from the second engaging portion provided on the rear case. In the present invention, by manipulating the driving mechanism, the first engaging portion and the second engaging portion on the inner surface of the rear shell can be fastened or separated, thereby realizing the installation and disassembly of the rear shell, and the entire assembly and disassembly process is simple and easy. It is firm and reliable, and can obviously improve the aesthetics of the back of the display device.

Description

technical field [0001] The invention relates to the technical field of displays, in particular to a rear case fixing structure and a display device. Background technique [0002] With the maturity of flat panel display technology, users pay more and more attention to the aesthetics and detachability of display devices. The back cover of the existing display device often adopts two methods for fixing: one is the screw fixing method, that is to say, the back cover is fixed on the back of the backlight module by screws. Although this assembly is stable and reliable, it will affect the display. The overall aesthetics of the back of the device, the position between the screws is prone to gaps, resulting in light leakage and increasing the possibility of foreign objects entering the display device in the use environment. At present, most display devices in public places in the market are surrounded by the screen display area of ​​the display device. There are different degrees of...
