Description

Technical Field

[0001] This application belongs to the field of backlight module drop protection technology, specifically relating to a drop offset structure that improves module reliability. Background Technology

[0002] The backlight module is one of the key components of a liquid crystal display device. A liquid crystal display device includes a liquid crystal display panel and a backlight module. The liquid crystal display panel itself cannot emit light, and the backlight module needs to provide a uniformly distributed surface light source so that the liquid crystal display panel can display images normally.

[0003] Currently, the standard drop height for regular mobile phones is 0.8-1.0m, while customers generally require a drop height of 1.5-1.8m for rugged phones and POS products. The existing structural design cannot meet the customer's drop test requirements. During a drop from a height of 1.5-1.8m, the backlight module after assembly will shift around its perimeter, resulting in poor light leakage. Furthermore, the anti-drop misalignment structure is difficult to install accurately, which can easily lead to installation errors and waste time during the installation process.

[0004] To address the above issues, this application designs a drop offset structure to improve module reliability, thereby solving technical problems such as difficulty in meeting customer drop test requirements, which can lead to misalignment of the backlight module after product assembly, and the ease with which the drop offset structure can cause installation deviations. Utility Model Content

[0005] This application aims to address at least one of the technical problems existing in the prior art or related technologies.

[0006] Therefore, this application designs a drop offset structure to improve module reliability, so as to meet the customer's drop test and prevent the backlight module from shifting around after product assembly, so as to avoid installation deviation of the anti-drop offset structure.

[0007] This application provides a drop-off structure to improve module reliability, comprising: a housing; a backlight module installed inside the housing; four L-shaped limiting blocks, each located at one of the four corners of the backlight module; four first adhesive strips, each located on the left and right sides of the upper and lower parts of the backlight module, with each first adhesive strip located inside the adjacent L-shaped limiting block; four second adhesive strips, each located on the upper and lower parts of the left and right sides of the backlight module, with each second adhesive strip located inside the adjacent L-shaped limiting block; four L-shaped buffer adhesive strips, each located on the surface of the L-shaped limiting block; and snap-fit ​​mounting components, each located at both ends of the outer side of the L-shaped limiting block, for quick and precise snap-fit ​​mounting of the L-shaped limiting block.

[0008] In some possible embodiments, the surface of the L-shaped limiting block has a buffer groove, and the L-shaped buffer strip extends into the buffer groove.

[0009] In some possible embodiments, a plurality of buffer springs are connected to the bottom of the buffer groove, and the L-shaped buffer strips are all connected to the buffer springs.

[0010] In some possible embodiments, the snap-fit ​​mounting assembly includes: a mounting block, which is fixed to the outside of the L-shaped limiting block, and the outside of the mounting block has a shrinkage groove; and a limiting plate, which is fixed to the surface of the housing, and the inside of the limiting plate has a semi-circular slot.

[0011] In some possible embodiments, the snap-fit ​​mounting assembly further includes: a slider slidably connected to the shrink groove; a return spring, one end of which is connected to the shrink groove, and the slider is connected to the other end of the return spring; a fixing rod fixed to the outside of the slider; and a locking block fixed to the outside of the fixing rod, the locking block engaging with the locking groove, and the locking block being semi-circular.

[0012] In some possible embodiments, a fixing plate is fixed to the outside of the L-shaped limiting block, a threaded rod is threaded through the fixing plate, four threaded holes are opened on the surface of the housing, and each threaded hole is close to the corner of the backlight module, and the threaded rod is threadedly connected to the adjacent threaded hole.

[0013] Compared with the prior art, the technical solution provided in this application has at least the following beneficial effects:

[0014] This application provides a drop offset structure to improve module reliability. By optimizing the assembly design of the backlight module, the backlight module is fixed around its perimeter by adding a first and second adhesive strip. An L-shaped buffer strip provides cushioning protection, and the L-shaped limiting block effectively limits and reinforces the first and second adhesive strips. This facilitates meeting the customer's requirements for drop testing of the entire device from a height of 1.5-1.8m, improving the reliability of the backlight module product and solving the problem of light leakage caused by drops. Furthermore, the L-shaped limiting block allows for convenient and precise installation of components via snap-fit ​​installation, preventing installation deviations and shortening installation time.

Detailed Implementation

[0025] To better understand the above-mentioned objectives, features, and advantages of this application, the application will be further described in detail below with reference to the accompanying drawings and specific embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0026] Many specific details are set forth in the following description in order to provide a full understanding of this application. However, this application may also be implemented in other ways different from those described herein. Therefore, the scope of protection of this application is not limited to the specific embodiments disclosed below.

[0027] The following reference Figures 1 to 6 This application describes a drop offset structure for improving module reliability according to some embodiments.

[0028] Please see Figures 1 to 6This application provides a drop offset structure to improve module reliability in some embodiments, including: a housing 1; a backlight module 2 installed inside the housing 1; four L-shaped limiting blocks 3, each located at one of the four corners of the backlight module 2; four first adhesive strips 4, each located on the left and right sides of the upper and lower parts of the backlight module 2, with each first adhesive strip 4 located inside the adjacent L-shaped limiting block 3; and four second adhesive strips 5, each located on the upper and lower parts of the left and right sides of the backlight module 2, with each second adhesive strip 5 located inside the adjacent L-shaped limiting block 3.

[0029] In this embodiment, by optimizing the assembly design of the backlight module 2, the backlight module 2 is fixed around its perimeter by adding a first adhesive strip 4 and a second adhesive strip 5. The first adhesive strip 4 and the second adhesive strip 5 are both glued to the four corners of the backlight module 2 by dotting adhesive, thereby forming vertical and horizontal limiting protection at the four corners of the backlight module 2. The first adhesive strip 4 and the second adhesive strip 5 are then reinforced by L-shaped limiting blocks 3, which helps to prevent the first adhesive strip 4 and the second adhesive strip 5 from loosening, thereby preventing the backlight module 2 from shifting in four directions and ensuring the stability of the backlight module 2 in drop tests.

[0030] In some embodiments, four L-shaped buffer strips 8 are all disposed on the surface of the L-shaped limiting block 3. The surface of the L-shaped limiting block 3 has a buffer groove 9. The L-shaped buffer strips 8 extend into the buffer groove 9. A plurality of buffer springs 10 are connected to the bottom of the buffer groove 9. The L-shaped buffer strips 8 are all connected to the buffer springs 10.

[0031] In this embodiment, the L-shaped buffer strip 8 provides cushioning protection for the dropped backlight module 2. The L-shaped buffer strip 8 compresses the buffer spring 10 in the buffer groove 9 to achieve cushioning protection during the drop, thus better protecting the backlight module 2 and better preventing the backlight module 2 from shifting. In summary, the combined design of the first point adhesive strip 4, the second point adhesive strip 5, the L-shaped buffer strip 8, and the L-shaped limiting block 3 helps to meet the customer's requirements for drop testing of the whole machine from a height of 1.5-1.8m, improves the reliability of the backlight module product, and solves the problem of light leakage caused by the drop.

[0032] In some embodiments, the snap-fit ​​mounting components are all located at both ends of the outer side of the L-shaped limiting block 3 for quick and precise snap-fit ​​mounting of the L-shaped limiting block 3. Each snap-fit ​​mounting component includes: a mounting block 6, which is fixed to the outer side of the L-shaped limiting block 3, and the outer side of the mounting block 6 has a shrinkage groove 11; a limiting plate 7, which is fixed to the surface of the housing 1, and the inner side of the limiting plate 7 has a semi-circular slot 16. Each snap-fit ​​mounting component also includes: a slider 12, which is slidably connected to the shrinkage groove 11; a return spring 13, one end of which is connected to the shrinkage groove 11, and the other end of the slider 12 is connected to the return spring 13; a fixing rod 14, which is fixed to the outer side of the slider 12; and a locking block 15, which is fixed to the outer end of the fixing rod 14, and the locking block 15 is engaged with the slot 16 and is semi-circular.

[0033] In this embodiment, when installing the L-shaped limiting block 3, the block 15 is first pushed into the slot 16 by its arc surface. During this process, the block 15 pushes the slider 12 into the shrinkage groove 11, and the slider 12 compresses the return spring 13. When the block 15 is aligned with the slot 16, the return force of the return spring 13 will cause the block 15 to be engaged in the slot 16. Therefore, it is convenient and accurate to install the L-shaped limiting block 3 to the first adhesive strip 4 and the second adhesive strip 5 through the snap-on installation assembly, thereby reinforcing the first adhesive strip 4 and the second adhesive strip 5. The installation process is convenient and accurate, avoiding installation deviation, and the installation time is short.

[0034] In some embodiments, a fixing plate 17 is fixed to the outside of the L-shaped limiting block 3, and a threaded rod 18 is threaded through the fixing plate 17. Four threaded holes 19 are opened on the surface of the housing 1, and each threaded hole 19 is close to the corner of the backlight module 2. The threaded rod 18 is threadedly connected to the adjacent threaded hole 19.

[0035] In this embodiment, by tightening the threaded rod 18 on the fixing plate 17 into the threaded hole 19 on the housing 1, the L-shaped limiting block 3 is more securely fixed and installed, which better prevents the L-shaped limiting block 3 from falling off, and also helps to better limit and protect the four corners of the backlight module 2.
