Description

Technical Field

[0001] The utility model relates to the field of backlight iron frames, and in particular to a module for enhancing the overlap of upper and lower iron frames. Background Art

[0002] In the display module, the backlight frame is an important structural component, and its main function is to support and fix the various components in the backlight unit. The backlight unit is a key component of the liquid crystal display because it provides the light source required by the display, allowing the LCD screen to display images. The backlight frame is usually made of metal materials and has sufficient strength and rigidity to maintain the structural stability of the backlight unit. It usually includes the following functions: Support structure: The backlight frame provides support for the reflector, light guide plate, diffuser, prism sheet and light source in the backlight unit. Positioning and fixing: The frame ensures that the various components in the backlight unit are properly aligned and fixed in place to ensure uniform distribution and efficient use of light. Heat dissipation: Since the light source in the backlight unit generates heat, the backlight frame sometimes also assumes a certain heat dissipation function to help conduct heat away from the light source. Shielding electromagnetic interference: In some designs, the backlight frame may also play a role in shielding electromagnetic interference, protecting the electronic components of the display from interference from external electromagnetic fields. The design and manufacturing quality of the backlight frame directly affects the performance and reliability of the display module. A stable and precise backlight iron frame can ensure the display has good brightness uniformity, low power consumption and long life. Therefore, the design and assembly of the backlight iron frame is a critical step in the manufacturing process of the display module.

[0003] In the prior art, such as the Chinese patent document with application number CN202322331201.7, which discloses a lightweight backlight iron frame for a display module, which can ensure the strength of the backlight iron frame while reducing the weight of the backlight iron frame and improving the heat dissipation effect through an opening opened on the backlight iron frame, a hollow plate in the opening, and a hollow pattern designed in the hollow plate. At the same time, according to the designed thermal conductive columns, thermal conductive connecting columns, heat dissipation fins and other structures, the heat dissipation capacity of the backlight iron frame can be further enhanced, and the overall heat dissipation capacity of the backlight module can be improved. In addition, by designing a dustproof net on the opening, dust can be prevented from entering the interior of the back iron frame, thereby achieving the purpose of greatly reducing the weight of the backlight.

[0004] The technical solution disclosed in the above patent document solves the problem of the weight of the backlight iron frame itself, but in the conventional design, there are still some problems in the assembly process of the backlight iron frame itself. The upper iron frame is connected to the backlight iron frame by matching with the upper iron frame to prevent static electricity and conduct static electricity from the upper iron frame. This solution requires an interference fit, which will make the connection between the upper iron frame and the backlight iron frame tighter, which is easy to cause the tail iron sheet at the matching position to tilt up (refer to Figure 1 ), the size exceeds the standard, affecting customer assembly.

[0034] 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.

[0035] As mentioned in the background technology, there are still some problems in the assembly process of the backlight iron frame in the conventional design. The upper iron frame is connected to the backlight iron frame in order to prevent static electricity and conduct static electricity from the upper iron frame. This solution requires an interference fit, which will make the connection between the upper iron frame and the backlight iron frame tighter, and it is easy to cause the tail iron sheet at the matching position to warp (refer to Figure 1 ), the size exceeds the standard, affecting the customer's assembly problem.

[0036] In order to solve this technical problem, the utility model provides a module for strengthening the overlap of upper and lower iron frames.

[0037] Specifically, please refer to Figure 1-Figure 10 , strengthen the upper and lower iron frame overlap module, including:

[0038] An upper iron frame 1 is provided with a lap groove 2, and the groove edge of the lap groove 2 has a bending section 3, and the bending section 3 is bent toward one side of the lap groove 2;

[0039] The backlight iron frame 4 has a lap section 5 matching the lap groove 2, and the lap section 5 can be elastically deformed when it abuts against the inner wall of the lap groove 2;

[0040] The housing 6 has an inserting area 7 thereon. When the upper iron frame 1 and the backlight iron frame 4 are overlapped, an iron frame structure that can be assembled into the inserting area 7 is formed.

[0041] The utility model can solve the problem of the tail end iron sheet being lifted up at the matching position by cooperating with the bending section 3 and the overlapping section 5, so that after the upper iron frame 1 and the backlight iron frame 4 are overlapped, the bending section 3 can normally enter the plug-in area 7. Specifically, the upper iron frame 1 is directly guided to cooperate with the backlight iron frame 4. When the upper iron frame 1 and the backlight iron frame 4 are overlapped, an iron frame structure that can be assembled into the plug-in area 7 is formed. At the same time, when the iron frame structure is assembled into the plug-in area 7, the inner side wall of the plug-in area 7 will push the bending section 3 to move toward the side of the overlapping groove 2.

[0042] Compared with the prior art, the utility model makes an arc at the tail end of the upper iron frame 1 at the overlap position, and the inner side of the backlight iron frame 4 at the overlap position is suspended, and the casing 6 is correspondingly made into a top position. During assembly, the upper and lower iron frames are squeezed to ensure conduction, thereby ensuring conduction and avoiding the problem of assembly patching.

[0043] 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.

[0044] 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.

[0045] 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.

[0046] A module for enhancing the overlap of upper and lower iron frames, comprising: an upper iron frame 1, on which an overlap groove 2 is provided, and the groove edge of the overlap groove 2 has a bending section 3, and the bending section 3 is bent toward one side of the overlap groove 2; a backlight iron frame 4, on which an overlap section 5 matching the overlap groove 2 is provided, and the overlap section 5 can be elastically deformed when abutting against the inner side wall of the overlap groove 2; a casing 6, on which an insertion area 7 is provided, and when the upper iron frame 1 and the backlight iron frame 4 are overlapped, an iron frame structure that can be assembled into the insertion area 7 is formed. The utility model can solve the problem of the tail end iron sheet being lifted up at the matching position by cooperating with the bending section 3 and the overlapping section 5, so that after the upper iron frame 1 and the backlight iron frame 4 are overlapped, the bending section 3 can normally enter the plug-in area 7. Specifically, the upper iron frame 1 is directly guided to cooperate with the backlight iron frame 4. When the upper iron frame 1 and the backlight iron frame 4 are overlapped, an iron frame structure that can be assembled into the plug-in area 7 is formed. At the same time, when the iron frame structure is assembled into the plug-in area 7, the inner side wall of the plug-in area 7 will push the bending section 3 to move toward the side of the overlapping groove 2.

[0047] In some specific embodiments, the end of the bending section 3 away from the lap groove 2 is at most flush with the notch edge of the lap groove 2. This arrangement is to prevent the bending section 3 from exceeding the notch edge of the lap groove 2, thereby avoiding the phenomenon of the bending section 3 being blocked when the iron frame structure is assembled into the insertion area 7.

[0048] Figure 6 The middle A represents the backlight plastic frame. During assembly, the raised position of the upper iron frame (i.e., the bent section 3) can be assembled into the plastic shell.

[0049] The module for enhancing the overlap of the upper and lower iron frames provided in Example 1 is further optimized. The upper iron frame 1 includes a main body 8, and a clamping section 9 is provided at the end of the main body 8. The lap groove 2 is formed between the end of the main body 8 and the clamping section 9. The bending section 3 is provided at the end of the clamping section 9 away from the main body 8. The clamping section 9 matches the lap section 5, and the position of the bending section 3 is equivalent to that in the prior art. Figure 3 The position of the tail iron sheet is shown in FIG.

[0050] In some specific embodiments, the overlapping section 5 is integrally formed with the backlight iron frame 4, and notches 10 are provided at both ends of the overlapping section 5 to guide the overlapping section 5 to elastically deform within a set range. Two notches 10 are provided on the left and right sides of the overlapping portion of the backlight iron frame 4 to prevent the entire backlight iron frame 4 from being deformed when squeezed.

[0051] In some specific embodiments, the lap section 5 includes a compression section 11 and a deformation section 12 located at both ends of the compression section 11 and integrally formed with the backlight iron frame 4. The cutout 10 is arranged in the deformation section 12 and located on the side of the compression section 11 away from the clamping section 9. This arrangement is to make the state of the lap section 5 after being compressed be Figure 7 The state shown ensures that the normal use of the overlapping section 5 is not affected during the fitting process.

[0052] In some specific embodiments, the structure of the plug-in area 7 matches the upper iron frame 1. This arrangement is to enable the upper iron frame 1 to be fully accommodated in the plug-in area 7.

[0053] In some specific embodiments, a push block 13 is provided on the side wall of the plug-in area 7, and the push block 13 can push the bending section 3 to move toward one side of the lap groove 2 when the iron frame structure is assembled into the plug-in area 7. This arrangement is to enable the raised portion of the bending section 3 to move toward one side of the lap groove 2, and the iron frame structure will not be tilted after being assembled into the plug-in area 7.

[0054] The module for enhancing the overlap of the upper and lower iron frames provided in Example 1 or 2 is further optimized, and the push block 13 includes a pressure strip 14 arranged in the plug-in area 7, and a guide slope 15 is arranged at the end of the pressure strip 14 along the direction in which the iron frame structure is assembled into the plug-in area 7. This arrangement is to make it easier for the tilted bending section 3 to enter the plug-in area 7, and at the same time, after fully entering the plug-in area 7, the guide slope 15 can push the bending section 3 to move toward one side of the overlap groove 2 until the bending section 3 can be assembled into the plastic shell.

[0055] In some specific embodiments, along the direction of the iron frame structure being assembled into the plug-in area 7, the bending section 3 is provided with points A, B and C, wherein an arc guide surface that cooperates with the guide slope 15 is formed between points B and C. Such a configuration is for the purpose of guiding the bending section 3 to enter the plug-in area 7 through the arc guide surface when the arc guide surface contacts the edge of the plug-in area 7, thereby guiding the bending section 3 to enter the plug-in area 7 without being blocked by the edge of the plug-in area 7.

[0056] In some specific implementations, the point C is located between the point A and the point B, based on the horizontal direction of the overlapping groove 2 .

[0057] This arrangement is to ensure that the length of the arc guide surface is sufficient, and the situation in which the bending section 3 abuts against the edge of the insertion area 7 due to the insufficient length of the arc guide surface will not occur.

[0058] The use process of the module for enhancing the overlap of the upper and lower iron frames provided by the utility model is as follows: the utility model can solve the problem of the tail end iron sheet being tilted at the matching position by cooperating with the bending section 3 and the overlapping section 5, so that after the upper iron frame 1 is overlapped with the backlight iron frame 4, the bending section 3 can normally enter the plug-in area 7. Specifically, the upper iron frame 1 is directly guided to cooperate with the backlight iron frame 4. When the upper iron frame 1 is overlapped with the backlight iron frame 4, an iron frame structure that can be assembled into the plug-in area 7 is formed. At the same time, when the iron frame structure is assembled into the plug-in area 7, the inner side wall of the plug-in area 7 will push the bending section 3 to move toward the side of the overlapping groove 2.
