Description

Technical Field

[0001] This utility model relates to the field of liquid crystal display modules, and in particular to a composite connection structure based on liquid crystal display modules. Background Technology

[0002] With the trend of miniaturization and high performance in electronic devices, the reliability and flexibility of the connection structure of LCD modules, as key components, are becoming increasingly important. As electronic devices become more feature-rich, the requirements for data transmission rate and signal stability between display modules and other components are constantly increasing. Traditional connection structures are unable to meet the needs of high-speed and high-capacity data transmission, thus limiting the improvement of overall device performance.

[0003] In existing technologies, during the assembly of LCD displays, the connection between the LCD panel and the back module via clips is more convenient than bolt connections. However, when LCD displays are used in scenarios such as automotive displays, industrial monitoring, or mobile terminals that require long-term exposure to complex vibrations, the contact interface between the clips and slots will face multiple stress challenges. High-frequency vibrations can cause the clip structure to undergo micron-level back-and-forth displacement, accelerating the fatigue deformation of the elastic material. This leads to the gradual increase in the fit gap and the attenuation of contact pressure in the originally precisely fitted clip structure, ultimately manifesting as loose connections, abnormal noises, or even misalignment of the optical module and other quality defects. Therefore, it is necessary to improve the composite connection structure based on the LCD display module to solve the above problems. Utility Model Content

[0004] To overcome the problem that vibration can cause the locking block to shift during actual use, ultimately leading to the detachment of components, etc., in the snap-fit ​​connection method.

[0005] The technical solution of this utility model is as follows: a composite connection structure based on a liquid crystal display module, including a front panel frame, a first slider and a docking mechanism, a first slider slidably connected inside the front panel frame, a first locking block fixedly connected to the first slider, a liquid crystal panel module body locked onto the first locking block, a first fixing block fixedly connected to the front panel frame, a back panel frame provided outside the front panel frame, a backlight module body provided inside the back panel frame, a middle frame provided between the front panel frame and the back panel frame, a fixing seat fixedly connected to the back panel frame, and a second slider slidably connected to the fixing seat. A second locking block is fixedly connected to the second slider, and the second locking block is locked inside the first fixing block. A pressing block is slidably connected to the outer frame of the back plate, and a first connecting plate is fixedly connected to the pressing block. A first connecting rod is fixedly connected to the first connecting plate, and a first fixing rod is fixedly connected to the first connecting rod. The first fixing rod is slidably connected inside the second slider. A second fixing block is fixedly connected to the outer frame of the back plate, and a threaded rod is threadedly connected inside the second fixing block. One end of the threaded rod is rotatably connected to a limit block, and the limit block is slidably connected inside the second fixing block. The limit block is locked inside the pressing block.

[0006] Preferably, the LCD panel module body has a slot at the relative position of the first card block, and the first card block is snapped into the inside of the slot.

[0007] Preferably, the fixing seat has a limiting groove at the relative position of the second slider, and the second slider is slidably connected inside the groove.

[0008] Preferably, the limiting block has a rotating groove at the relative position of the threaded rod, and the threaded rod is rotatably connected inside the rotating groove.

[0009] Preferably, a pull plate is slidably connected inside the front panel outer frame, a first spring is fixedly connected between the pull plate and the front panel outer frame, a second fixing rod is fixedly connected to the pull plate, the second fixing rod is slidably connected inside the first slider, and a second spring is fixedly connected between the second slider and the fixing seat.

[0010] Preferably, the front panel outer frame has a groove at the relative position of the pull plate, and the pull plate is slidably connected inside the groove.

[0011] Preferably, the docking mechanism includes a second connecting plate, which is fixedly connected to the LCD panel module body. A first docking plate is fixedly connected to the middle frame, and the second connecting plate is snapped onto the first docking plate. A third connecting plate is fixedly connected to the middle frame, and the second docking plate is fixedly connected to the backlight module body. The third connecting plate is snapped onto the second docking plate.

[0012] The beneficial effects of this utility model are:

[0013] 1. Compared to the traditional snap-fit ​​method, this design uses the middle frame to limit the first snap-fit ​​block, and the limiting block to limit the pressing block, preventing the first and second snap-fit ​​blocks from disengaging. During subsequent handling and movement, the snap-fit ​​blocks are difficult to disengage regardless of the direction of force applied, greatly enhancing the stability and reliability of the LCD screen. This provides a strong guarantee for the long-term stable operation of the screen and avoids the problem of snap-fit ​​connections where vibration can cause the snap-fit ​​blocks to shift and ultimately lead to the detachment of components.

[0014] 2. Compared to the traditional manual alignment method, the assembly process uses a docking mechanism to align the LCD panel module body, the middle frame, and the backlight module body, making the positioning of each module more accurate. This avoids display problems caused by assembly errors, such as screen offset and uneven color. At the same time, the modular design makes the assembly process of each component faster, reduces the overall assembly time, and improves production efficiency. Attached Figure Description

[0023] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0024] Please see Figure 1 - Figure 6This utility model provides an embodiment of a composite connection structure based on a liquid crystal display module, including a front panel frame 1, a first slider 21, and a docking mechanism. The first slider 21 is slidably connected inside the front panel frame 1, and a first locking block 22 is fixedly connected to the first slider 21. A liquid crystal panel module body 4 is locked to the first locking block 22. A first fixing block 23 is fixedly connected to the front panel frame 1. A back panel frame 7 is provided outside the front panel frame 1, and a backlight module body 6 is provided inside the back panel frame 7. A middle frame 5 is provided between the front panel frame 1 and the back panel frame 7. A [missing information - likely a component or mechanism] is fixedly connected to the back panel frame 7. A fixed base 25 has a second slider 26 slidably connected to it. A second locking block 24 is fixedly connected to the second slider 26 and engages with the inside of a first fixed block 23. A pressing block 210 is slidably connected to the outer frame 7 of the back plate. A first connecting plate 29 is fixedly connected to the pressing block 210. A first connecting rod 28 is fixedly connected to the first connecting plate 29. A first fixing rod 27 is fixedly connected to the first connecting rod 28 and slidably connected to the inside of the second slider 26. A second fixing block 211 is fixedly connected to the outer frame 7 of the back plate. The second fixing block 211 has an internal threaded connection. A threaded rod 212 has a rotatable connection at one end to a limiting block 213. The limiting block 213 is slidably connected inside the second fixed block 211 and is snapped into the inside of the pressing block 210. During use, after the LCD panel module body 4 is placed inside the front panel outer frame 1, the first slider 21 slides, causing the first locking block 22 to engage with the LCD panel module body 4. After the LCD panel module body 4 is installed and connected to the front panel outer frame 1, the docking mechanism and its components dock and install the LCD panel module body 4 with the middle frame 5. At this time, the middle frame 5 restricts the sliding of the first slider 21, preventing... After the first slider 21 slides out, the backlight module body 6 and the middle frame 5 are connected and installed through the docking mechanism. Then, the back panel outer frame 7 is fastened to the back of the backlight module body 6. The back panel outer frame 7 contacts the backlight module body 6, restricting the position of the backlight module body 6. Then, the second slider 26 slides to drive the second locking block 24 to engage with the first fixing block 23, so that the back panel outer frame 7 is installed and connected with the front panel outer frame 1. Then, the threaded rod 212 is rotated. When the threaded rod 212 rotates, it cooperates with the second fixing block 211 to drive the limiting block 213 to slide into the pressing block 210, limiting the pressing block 210, thus completing the installation.

[0025] Please see Figure 1 - Figure 6In this embodiment, the LCD panel module body 4 has a slot at a position relative to the first locking block 22. The first locking block 22 is engaged with the inside of the slot. When the LCD panel module body 4 is engaged with the first locking block 22 through the slot, it is installed together with the front panel frame 1. Compared with the bolt connection, this is faster and more efficient. The fixing seat 25 has a limiting groove at a position relative to the second slider 26. The second slider 26 is slidably connected to the inside of the groove. The groove restricts the sliding of the second slider 26 and prevents it from tilting when sliding, which would affect the engagement between the second locking block 24 and the first fixing block 23. The limiting block 213 has a rotating groove at a position relative to the threaded rod 212. The threaded rod 212 is rotatably connected to the inside of the rotating groove. The rotating groove ensures that the threaded rod 212 drives the limiting block when rotating. The sliding of block 213 restricts the pressing block 210. A pull plate 214 is slidably connected inside the front plate outer frame 1. A first spring 215 is fixedly connected between the pull plate 214 and the front plate outer frame 1. A second fixing rod 216 is fixedly connected to the pull plate 214. The second fixing rod 216 is slidably connected inside the first slider 21. A second spring 217 is fixedly connected between the second slider 26 and the fixing seat 25. The first spring 215 provides a pushing force to the pull plate 214. When the pull plate 214 is released, it drives the pull plate 214 to automatically return to its original position. A groove is provided in the front plate outer frame 1 at the relative position of the pull plate 214. The pull plate 214 is slidably connected inside the groove. The groove restricts the sliding of the pull plate 214 and prevents the pull plate 214 from tilting when sliding, which would affect the subsequent sliding of the first slider 21.

[0026] Please see Figure 2 , Figure 7 In this embodiment, the docking mechanism includes a second connecting plate 31, which is fixedly connected to the LCD panel module body 4. A first docking plate 32 is fixedly connected to the middle frame 5, and the second connecting plate 31 is snapped onto the first docking plate 32. A third connecting plate 33 is fixedly connected to the middle frame 5, and a second docking plate 34 is fixedly connected to the backlight module body 6, with the third connecting plate 33 snapped onto the second docking plate 34. During use, the second connecting plate 31 docks with the first docking plate 32, and the third connecting plate 33 docks with the second docking plate 34, thus restricting the connection between the LCD panel module body 4, the middle frame 5, and the backlight module body 6. This prevents the LCD panel module body 4, the middle frame 5, and the backlight module body 6 from tilting after the front panel outer frame 1 and the back panel outer frame 7 are snapped together, which would affect subsequent use.

[0027] During operation, the pull plate 214 is pulled upwards. As it moves, the second fixing rod 216 causes the first slider 21 to slide outwards, thereby moving the first locking block 22 away from the outside. After the LCD panel module body 4 is placed inside the front panel outer frame 1, the pull plate 214 is released. The first spring 215 provides a pushing force to the pull plate 214, pushing it back to its original position. This causes the first locking block 22 to engage with the LCD panel module body 4, completing the installation of the LCD panel module body 4. Then, the first mating plate 32 is aligned with the second connecting plate 31, and the middle frame 5 is placed outside the front panel outer frame 1. At this point, the middle frame 5 restricts the sliding of the first slider 21, preventing subsequent sliding of the first slider 21 from causing the first locking block 22 to detach from the LCD panel module body 4. Finally, the second mating plate 34 is aligned with the third connecting plate 33, and the backlight module body 6 is placed outside the middle frame 5, completing the installation and assembly of the backlight module body 6. After the main body 6 is pressed, the pressing block 210 moves, causing the first connecting plate 29 to move. The first connecting plate 29 moves, causing the first connecting rod 28 to move. When the first connecting rod 28 moves, it drives the second slider 26 and the second locking block 24 to slide outward through the first fixing rod 27. After the back panel frame 7 is fastened to the back of the backlight module main body 6, the pressing block 210 is released. The second spring 217 provides a pushing force to the second slider 26, pushing the second locking block 24 and the first... The fixing block 23 engages, connecting and fixing the back panel outer frame 7 to the front panel outer frame 1 while restricting the position of the backlight module body 6. Then, the second slider 26 slides to drive the second locking block 24 to engage with the first fixing block 23, so that the back panel outer frame 7 and the front panel outer frame 1 are installed and connected. Then, the threaded rod 212 is rotated. When the threaded rod 212 rotates, it cooperates with the second fixing block 211 to drive the limiting block 213 to slide into the pressing block 210, thereby limiting the pressing block 210 and completing the installation.

[0028] Through the above steps, compared with the traditional snap-fit ​​method, the middle frame 5 limits the first snap-fit ​​block 22, and the limiting block 213 limits the pressing block 210, so as to solve the problem that vibration will cause the snap-fit ​​block to shift during actual use, and eventually cause the components to detach.
