[0032] It should be noted that similar reference numerals and letters denote similar items in the following drawings, and therefore, once an item is defined in one drawing, further definition and explanation thereof is not required in subsequent drawings.

[0033] Please refer to Figure 1-5 A replaceable backlight guide plate comprises a frame 1, an LED module 2 and a backlight guide plate 3. A socket 4 is provided on one side of the frame 1. The LED module 2 is installed in the frame 1. The backlight guide plate 3 is inserted into the frame 1 through the socket 4.

[0034] The protective film 5 is fixedly connected to the socket 4. A groove 6 is provided on one side of the frame 1 and at both ends of the socket 4. A limiting component 7 is provided inside the groove 6. The limiting component 7 is used to limit the backlight guide plate 3 after installation.

[0035] Please refer to Figure 2 and 4 The LED module 2 includes a diffusion sheet 201, a reflection sheet 202 and an LED lamp 203 connected in sequence. This arrangement makes the light source of the LED lamp 203 more uniform and improves the effect of the backlight guide plate 3.

[0036] Please refer to Figure 1 and Figure 2 The socket 4 is opened on the upper side, left side or right side of the frame 1.

[0037] The replaceable light guide plate solution provided in this embodiment is that when in use, the backlight guide plate 3 is inserted into the interior of the frame 1 from the socket 4. Since the socket 4 is opened on the upper side, left side or right side of the frame 1, the socket 4 will not be located at the bottom when placed, thereby preventing the backlight guide plate 3 from falling out of the socket 4 due to vibration, which is safer when in use.

[0038] The replaceable light guide plate solution provided in Example 1 is further optimized. Specifically, Figure 3 As shown, the protective film 5 is an aluminum film, and the protective film 5 is fixedly connected to the socket 4 by gluing.

[0039] Through the above-mentioned structural design, after the backlight guide plate 3 is inserted into the interior of the frame 1 from the socket 4, the protective film 5 is fixed to the socket 4 by gluing. Since the protective film 5 is an aluminum film, it not only prevents the backlight guide plate 3 from falling out of the socket 4, but also the aluminum film has good light-shielding properties and can reduce light loss, thereby playing a dual protection role.

[0040] The replaceable light guide plate solution provided in Example 1 or 2 is further optimized, such as Figure 2 and Figure 3 As shown, the stopper assembly 7 includes a fixing plate 701 fixedly connected to the inner wall of the groove 6 on the right side, the left side of the fixing plate 701 is fixedly connected to a hook 702, the fixing plate 701 may be integrally formed with the frame 1;

[0041] When installing the backlight guide plate 3 in this way, force is applied to the hook 702. Since the fixing sheet 701 is thin and slightly elastic, the hook 702 will move away from the socket 4. Then the backlight guide plate 3 is inserted into the interior of the frame 1 from the socket 4, and then the hook 702 is released. At this time, the elasticity of the fixing sheet 701 resets the hook 702 and presses the backlight guide plate 3 to limit it to prevent it from falling out during use. When disassembling, the hook 702 can be pressed by hand and force can be applied to release the limit on the backlight guide plate 3, thereby facilitating the removal of the backlight guide plate 3.

[0042] The replaceable light guide plate solution provided in the above embodiments is further optimized, such as Figure 5 As shown, the limiting assembly 7 includes a movable block 711 arranged inside the groove 6, the middle part of the movable block 711 is rotatably connected to the inner wall of the groove 6 through a pin shaft 712, a clamping block 713 is fixedly connected to the left side of the movable block 711, and a spring 714 is installed between the right side of the movable block 711 and the inner wall of the groove 6.

[0043] With such a structural design, when installing the backlight guide plate 3, force is applied to the right side of the movable block 711. At this time, the movable block 711 rotates around the pin shaft 712 and drives the clamping block 713 away from the socket 4. At the same time, the spring 714 will be compressed. Then the backlight guide plate 3 is inserted into the interior of the frame 1 from the socket 4, and then the movable block 711 is released. At this time, the elasticity of the spring 714 resets the movable block 711 and drives the clamping block 713 to press the backlight guide plate 3 to limit it to prevent it from falling out during use. When disassembling, the right side of the movable block 711 can be pressed by hand and force can be applied to release the limit on the backlight guide plate 3, and the backlight guide plate 3 is very convenient to take out.

[0044] The use process of the replaceable light guide plate solution provided by the utility model is as follows:

[0045] By setting the protective film 5 as an aluminum film, not only can the backlight guide plate 3 be prevented from falling out of the socket 4, but the aluminum film has a good light-shielding property, which can reduce light loss and play a double protective role. When replacing, the protective film 5 is peeled off from the socket 4, and then force is applied to the hook 702. Since the fixing sheet 701 is thin and slightly elastic, the hook 702 will move away from the socket 4. Then the backlight guide plate 3 is taken out, and the new backlight guide plate 3 is inserted into the interior of the frame 1 from the socket 4. Since the socket 4 is opened on the upper side of the frame 1, On the left or right side, the socket 4 will not be at the bottom when placed, thereby preventing vibration from causing the backlight guide plate 3 to fall out of the socket 4, and then release the hook 702. At this time, the elasticity of the fixing plate 701 resets the hook 702 and presses the backlight guide plate 3 to limit it, preventing it from falling out during use. When disassembling, you can press the hook 702 by hand and apply force to release the limit on the backlight guide plate 3, making it easy to take out the backlight guide plate 3, bringing convenience to the inspection of the backlight guide plate 3, avoiding discarding the entire backlight module, and being more economical and practical.
