Description

Technical Field

[0001] The utility model relates to the technical field of display modules, in particular to a backlight rear iron frame which can prevent the generation of debris. Background Art

[0002] In the backlight module structure, due to the limitation of the client shell (customer requirements), the overall thickness of the backlight module must meet the customer's requirements. One of the more important structures in the backlight module composition structure is the iron frame. When the backlight module is assembled, there is a middle rubber frame and a rear iron frame structure, and there is also a middle rubber frame and a rear rubber frame structure. For large-size display modules, the backlight module also has a middle rubber iron and a rear iron frame structure, and there are aluminum castings and other structures. Among them, as in the Chinese patent document with application number CN202122060788.3, ​​which discloses an iron frame for a backlight module and its backlight module and display screen, it is a common middle rubber frame and a rear iron frame structure in the backlight module. It changes the thickness of the back plate of the iron frame by stamping a convex bulge on the back plate of the iron frame. The increase in the thickness of the back plate of the iron frame can reduce the thickness of the light guide plate and reduce the processing difficulty of the light guide plate without changing the overall thickness of the iron frame, thereby ensuring that the overall thickness of the backlight meets customer requirements, reduces material and processing costs, and improves efficiency.

[0003] Although the technical solution disclosed in the above patent document solves the problem of customer's size requirement, it has limitations in actual operation, because one of the undesirable phenomena of the backlight is that the viewing area is dirty. One of the reasons for the dirt is the debris generated during the material assembly process, which enters the viewing area after a series of processes such as transportation, transfer, and shaking. The generation of debris mostly comes from the friction between the middle rubber frame and the iron frame. Under normal circumstances, the friction between the middle rubber frame and the iron frame will not generate debris. However, the edge of the iron frame and the inner wall of the middle rubber frame are both right angles. After the middle rubber frame and the iron frame are plugged in, the gap between the two becomes smaller, and the right angle is easy to shovel off the debris, resulting in dirt. Utility Model Content

[0028] In order to enable those skilled in the art to better understand the solution of the utility model, the technical solution in the embodiment of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiment of the utility model. Obviously, the described embodiment is only a part of the embodiment of the utility model, not all of the embodiments. Based on the embodiment of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the utility model.

[0029] As described in the background technology, one undesirable phenomenon of the backlight is that the viewing area is dirty. One of the reasons for the formation of this dirt is the debris generated during the material assembly process, which enters the viewing area after a series of processes such as transportation, transfer, and shaking. The generation of debris mostly comes from the friction between the middle rubber frame and the iron frame. Under normal circumstances, the friction between the middle rubber frame and the iron frame will not produce debris. However, the edge of the iron frame and the inner wall of the middle rubber frame are both at right angles. After the middle rubber frame and the iron frame are plugged in, the gap between the two becomes smaller, and the right angle is easy to shovel off the debris, resulting in dirt.

[0030] In order to solve this technical problem, the utility model provides a backlight rear iron frame which can prevent the generation of debris.

[0031] Specifically, please refer to Figure 1-5 The backlight rear iron frame can be inserted into a groove provided on the middle rubber frame and matched with the backlight rear iron frame, and the backlight rear iron frame includes:

[0032] Laminating part 1;

[0033] The plug-in portion 2 is arranged at the edge of the fitting portion 1 and can be inserted into the embedding groove to guide the surface of the fitting portion 1 to be flush with the edge of the embedding groove;

[0034] The corner avoidance structure is arranged at one end of the plug-in portion 2 away from the fitting portion 1, and the corner avoidance structure can increase the contact surface between the plug-in portion 2 and the bottom of the embedding groove and / or the side wall of the groove.

[0035] The utility model can reduce the probability of backlight being dirty through the corner avoidance structure. Specifically, compared with the prior art, since the edge of the iron frame and the inner wall of the middle rubber frame are at right angles, after the middle rubber frame and the iron frame are plugged in, the gap between the two becomes smaller, and the right angle of the edge of the iron frame is easy to scratch the inner wall of the embedded groove and shovel off debris. In the present application, an corner avoidance structure is provided on the plug-in part 2 to increase the contact area between the plug-in part 2 and the bottom and / or side wall of the embedded groove, thereby reducing the right-angle friction and preventing debris from being easily generated.

[0036] In order to enable those skilled in the art to better understand the solution of the utility model, the technical solution in the embodiments of the utility model will be clearly and completely described below in conjunction with the accompanying drawings.

[0037] It should be noted that, in the absence of conflict, the embodiments of the present invention and the features and technical solutions in the embodiments may be combined with each other.

[0038] 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.

[0039] Example 1

[0040] Please refer to Figure 1-2 , a backlight rear iron frame for preventing the generation of debris, the backlight rear iron frame can be inserted into a bezel provided on a middle rubber frame and matching with the backlight rear iron frame, the backlight rear iron frame comprising:

[0041] Laminating part 1;

[0042] The plug-in portion 2 is arranged at the edge of the fitting portion 1 and can be inserted into the embedding groove to guide the surface of the fitting portion 1 to be flush with the edge of the embedding groove;

[0043] The corner avoidance structure is arranged at one end of the plug-in portion 2 away from the fitting portion 1, and the corner avoidance structure can increase the contact surface between the plug-in portion 2 and the bottom of the embedding groove and / or the side wall of the groove.

[0044] The utility model can reduce the probability of dirt generated by the backlight through the corner avoidance structure. Specifically, compared with the prior art in which the edges of the iron frame and the inner side wall of the middle rubber frame are all right angles, after the middle rubber frame and the iron frame are inserted into each other, when the gap between the two becomes smaller, the right-angle edge of the iron frame is likely to scrape against the inner wall of the embedding groove and shovel off debris. In this application, by setting a corner avoidance structure at the insertion part 2 to increase the contact surface between the insertion part 2 and the bottom and / or side wall of the embedding groove, the right-angle friction can be reduced, so that debris will not be easily generated.

[0045] In some specific embodiments, an embedding groove 3 is provided at the inner side wall of the bottom edge of the embedding groove corresponding to the insertion part 2, and the width of the embedding groove 3 is greater than or equal to the thickness of the surrounding strip 4. The embedding groove 3 is used to accommodate the insertion part 2, so that the friction between the embedding groove 3 and the inner wall of the bottom of the embedding groove is all in the area where the embedding groove 3 is located.

[0046] In some specific embodiments, the insertion part 2 includes a surrounding strip 4 connected to the edge of the fitting part 1. The longitudinal section of the structure formed by the combination of the surrounding strip 4 and the fitting part 1 is in the shape of a "U". An A area, a B area and a C area are provided at one end of the surrounding strip 4 away from the fitting part 1.

[0047] In some specific embodiments, the corner avoidance structure is a semi-circular structure. The corner avoidance structure can select a mat with a semi-circular surface. The inside of the mat is matched with the surrounding strip 4. The mat can be sleeved on the outside of the surrounding strip 4, or directly chamfered or blunted at the A area and the C area.

[0048] In some specific embodiments, the corner avoidance structure is arranged in the A area and the C area.

[0049] If the insertion part 2 is not provided with a corner avoidance structure, the A area and the C area are right angles. At this time, the A area is easy to contact with the bottom or side wall of the embedding groove (refer to Figure 2 That is, the A area scrapes against the bottom of the embedding groove, and at the same time, the A area scrapes against the side wall of the groove). In the case of shaking, the A area will also respectively abut against the bottom of the embedding groove and the edge of the bottom of the embedding groove (the connection part where the A area scrapes against the bottom and side wall of the embedding groove), that is, the purpose of abutting against the bottom and side wall of the embedding groove is achieved.

[0050] The corner avoidance structure is configured in the C area to reduce the scraping between the C area and the bottom of the embedding groove.

[0051] When Example 1 works, the surrounding strip 4 is directly inserted into the embedding groove until the B area on the surrounding strip 4 abuts against the inner wall of the bottom of the embedding groove 3. At this time, since the contact surfaces of the A area and the C area with the inner wall of the embedding groove 3 are both semi-circular structures (the diameter of the semi-circle can be selected as 0.6 mm), therefore, under the contact of the circular surface, no debris will be scraped out from the inner wall of the embedding groove 3.

[0052] Example 2

[0053] The backlight rear iron frame for preventing debris generation provided in Example 1 is further optimized. Specifically, Figure 3 As shown, the backlight rear iron frame can be inserted into a groove provided on the middle rubber frame and matched with the backlight rear iron frame, and the backlight rear iron frame includes:

[0054] Laminating part 1;

[0055] The plug-in portion 2 is arranged at the edge of the fitting portion 1 and can be inserted into the embedding groove to guide the surface of the fitting portion 1 to be flush with the edge of the embedding groove;

[0056] Angle avoidance structure, the angle avoidance structure is arranged at the end of the plug-in part 2 away from the fitting part 1, and the angle avoidance structure can increase the contact surface between the plug-in part 2 and the bottom of the embedded groove and / or the side wall of the groove. The utility model can reduce the probability of backlight dirt through the angle avoidance structure. Specifically, compared with the prior art, since the edge of the iron frame and the inner wall of the middle rubber frame are both right angles, after the middle rubber frame and the iron frame are plugged in, the gap between the two becomes smaller, and the right angle of the edge of the iron frame is easy to scratch the inner wall of the embedded groove and shovel off debris. In this application, by arranging an angle avoidance structure on the plug-in part 2 to increase the contact surface between the plug-in part 2 and the bottom of the embedded groove and / or the side wall of the groove, the right-angle friction can be reduced, so that debris will not be easily generated.

[0057] In some specific embodiments, an embedding groove 3 is provided at a position corresponding to the inserting portion 2 and the inner side wall of the bottom edge of the embedding groove, and the width of the embedding groove 3 is greater than or equal to the thickness of the surrounding strip 4. The embedding groove 3 is used to accommodate the inserting portion 2, so that the friction between the embedding groove 3 and the inner wall of the bottom of the embedding groove is in the area where the embedding groove 3 is located.

[0058] In some specific embodiments, an anti-wear strip 5 is installed in the embedding groove 3 (which can be fixed by bonding or embedding in the slot). The setting method of the anti-wear strip 5 can refer to Figure 3 The anti-wear strip 5 can be made of flexible materials such as rubber and sponge.

[0059] Based on Example 1, Example 2 adds an anti-wear strip 5, which further reduces the contact amount between the plug-in part 2 and the inner wall of the embedded groove 3. During operation, the surrounding strip 4 is directly inserted into the embedded groove until the area B on the surrounding strip 4 contacts the anti-wear strip 5. Due to the presence of the anti-wear strip 5, the area B will not directly contact the inner wall of the embedded groove 3, so the inner wall of the embedded groove 3 will not be scratched to produce debris.

[0060] Example 3

[0061] The backlight rear iron frame for preventing debris generation provided in embodiment 1 or 2 is further optimized, such as Figure 4As shown, the backlight rear iron frame can be inserted into a groove provided on the middle rubber frame and matched with the backlight rear iron frame, and the backlight rear iron frame includes:

[0062] Laminating part 1;

[0063] The plug-in portion 2 is arranged at the edge of the fitting portion 1 and can be inserted into the embedding groove to guide the surface of the fitting portion 1 to be flush with the edge of the embedding groove;

[0064] Angle avoidance structure, the angle avoidance structure is arranged at the end of the plug-in part 2 away from the fitting part 1, and the angle avoidance structure can increase the contact surface between the plug-in part 2 and the bottom of the embedded groove and / or the side wall of the groove. The utility model can reduce the probability of backlight dirt through the angle avoidance structure. Specifically, compared with the prior art, since the edge of the iron frame and the inner wall of the middle rubber frame are both right angles, after the middle rubber frame and the iron frame are plugged in, the gap between the two becomes smaller, and the right angle of the edge of the iron frame is easy to scratch the inner wall of the embedded groove and shovel off debris. In this application, by arranging an angle avoidance structure on the plug-in part 2 to increase the contact surface between the plug-in part 2 and the bottom of the embedded groove and / or the side wall of the groove, the right-angle friction can be reduced, so that debris will not be easily generated.

[0065] In some specific embodiments, an embedding groove 3 is provided at a position corresponding to the inserting portion 2 and the inner side wall of the bottom edge of the embedding groove, and the width of the embedding groove 3 is greater than or equal to the thickness of the surrounding strip 4. The embedding groove 3 is used to accommodate the inserting portion 2, so that the friction between the embedding groove 3 and the inner wall of the bottom of the embedding groove is in the area where the embedding groove 3 is located.

[0066] In some specific embodiments, the inner side wall of the embedding groove 3 is provided with an annular groove 6, and the annular groove 6 can be trapezoidal, V-shaped or U-shaped.

[0067] Embodiment 3 is based on Embodiment 1, and an annular groove 6 is added. When working, the surrounding strip 4 is directly inserted into the embedded groove until the area B on the surrounding strip 4 abuts against the inner wall of the bottom of the embedded groove 3. At this time, since the contact surfaces between the areas A and C and the inner wall of the embedded groove 3 are both semicircular structures (the diameter of the semicircle can be selected to be 0.6 mm), the inner wall of the embedded groove 3 will not be easily scratched to produce debris under the contact of the circular surface. Even if debris occurs, it will remain in the annular groove 6, thereby further preventing the occurrence of dirt.

[0068] Example 4

[0069] The backlight rear iron frame for preventing debris generation provided in the above embodiments is further optimized, such as Figure 5 As shown, the backlight rear iron frame can be inserted into a groove provided on the middle rubber frame and matched with the backlight rear iron frame, and the backlight rear iron frame includes:

[0070] Laminating part 1;

[0071] The plug-in portion 2 is arranged at the edge of the fitting portion 1 and can be inserted into the embedding groove to guide the surface of the fitting portion 1 to be flush with the edge of the embedding groove;

[0072] Angle avoidance structure, the angle avoidance structure is arranged at the end of the plug-in part 2 away from the fitting part 1, and the angle avoidance structure can increase the contact surface between the plug-in part 2 and the bottom of the embedded groove and / or the side wall of the groove. The utility model can reduce the probability of backlight dirt through the angle avoidance structure. Specifically, compared with the prior art, since the edge of the iron frame and the inner wall of the middle rubber frame are both right angles, after the middle rubber frame and the iron frame are plugged in, the gap between the two becomes smaller, and the right angle of the edge of the iron frame is easy to scratch the inner wall of the embedded groove and shovel off debris. In this application, by arranging an angle avoidance structure on the plug-in part 2 to increase the contact surface between the plug-in part 2 and the bottom of the embedded groove and / or the side wall of the groove, the right-angle friction can be reduced, so that debris will not be easily generated.

[0073] In some specific embodiments, an embedding groove 3 is provided at a position corresponding to the inserting portion 2 and the inner side wall of the bottom edge of the embedding groove, and the width of the embedding groove 3 is greater than or equal to the thickness of the surrounding strip 4. The embedding groove 3 is used to accommodate the inserting portion 2, so that the friction between the embedding groove 3 and the inner wall of the bottom of the embedding groove is in the area where the embedding groove 3 is located.

[0074] In some specific embodiments, the corner avoidance structure can be replaced by the plug-in portion 2 .

[0075] In some specific embodiments, the corner avoidance structure includes a connecting section 7 connected to the edge of the fitting portion 1, and the end of the connecting section 7 away from the fitting portion 1 is provided with a bending section 8, and the bending section 8 can be bent toward or away from the surface of one side of the inner side wall of the groove of the connecting section 7, and the end of the bending section 8 away from the connecting section 7 is connected to a lap section 9.

[0076] In some specific embodiments, the distance between the connecting section 7 and the overlapping section 9 is at most equal to the width of the embedding groove 3 .

[0077] Compared with the above embodiments, embodiment 4 is equivalent to folding the plug-in portion 2. During operation, the connecting section 7 is directly guided to be inserted into the embedding groove until the bent section 8 abuts against the bottom of the embedding groove 3. At this time, the surface of the bent section 8 is arc-shaped, so the inner wall of the embedding groove 3 will not be easily scratched to produce debris.

[0078] The use process of the backlight rear iron frame for preventing the generation of debris provided by the utility model is as follows: (using Example 1 as an example) directly insert the surrounding strip 4 into the embedding groove until the area B on the surrounding strip 4 abuts against the inner wall of the bottom of the embedding groove 3. At this time, since the contact surfaces between the areas A and C and the inner wall of the embedding groove 3 are both semicircular structures (the diameter of the semicircle can be selected to be 0.6mm), the inner wall of the embedding groove 3 will not be scratched to produce debris under the contact of the circular surface.
