Description

Technical Field

[0001] This utility model belongs to the field of display panel fixing technology, and in particular relates to a fixing structure for COB display panels. Background Technology

[0002] COB (Chip on Board) display panels refer to display panel technology that directly encapsulates chips onto a circuit board. In this technology, light-emitting chips (such as LED chips) are directly mounted and fixed onto the circuit board, and then protected and fixed by encapsulating glue or other methods to form an integrated display module.

[0003] Existing COB display panels are usually installed in a cabinet, which is then directly hung in a designated location. This can cause the cabinet to collide with objects when the position of the display panel needs to be adjusted, resulting in deformation of the cabinet and breakage of internal chips. To address this, we provide a fixing structure for COB display panels. Utility Model Content

[0004] The purpose of this utility model is to provide a fixing structure for a COB display panel. By using two springs to return, the limiting rod and the buckle are pushed to the left, so that the buckle is above the locking block. At the same time, the limiting rod enters the limiting groove to lock the protective shell. The installation is simple and quick. The protective shell protects the cabinet and solves the problem that when the position of the display panel needs to be adjusted, the cabinet may collide with objects, causing the cabinet to deform and the internal chips to break.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0006] This utility model is a fixing structure for a COB display panel, including a mounting part, which is used to install the COB display panel;

[0007] A protective section is installed inside the mounting section and is used to protect the COB display panel.

[0008] After the COB display panel is installed above the mounting section, the protective section blocks the cabling conduit of the COB display panel.

[0009] Furthermore, the mounting section includes an auxiliary component for assisting in the mounting of the COB display panel; and

[0010] A positioning component is installed inside the auxiliary component and is used to position the COB display panel.

[0011] Furthermore, the protective part includes a connecting component for connecting the mounting part;

[0012] A snap-fit ​​assembly, installed inside the auxiliary assembly, the snap-fit ​​assembly being used to snap-fit ​​the connecting assembly; and

[0013] A locking component, which is installed inside the auxiliary component, is used to lock the snap-fit ​​component;

[0014] In this process, after the connecting component is installed into the auxiliary component, the connecting component is snapped into place by a snap-fit ​​component, and then the snap-fit ​​component is locked in place by a locking component.

[0015] Furthermore, the auxiliary component includes a base plate, the front of which contacts the housing, a positioning rod is fixedly connected to the front of the base plate, a positioning hole is provided inside the housing, the inner wall of the positioning hole is adapted to the outer surface of the positioning rod, and the cooperation between the positioning hole and the positioning rod makes it easier to install the housing, and a fixing bolt is fixedly connected inside the housing;

[0016] The enclosure is positioned by using a positioning rod and a positioning hole, and then the enclosure is connected to the base plate by fixing bolts.

[0017] Furthermore, the positioning component includes a groove formed inside the base plate, and a slider is slidably connected to the inner wall of the groove. There are two sliders in total. A spring is fixedly connected to the side of the sliders that are close to each other. A connecting rod is rotatably connected to the top of the slider, and a positioning block is rotatably connected to the other end of the connecting rod. The positioning block is used to determine whether the box is tightly attached to the base plate.

[0018] The positioning blocks are used to position the box and check whether the box fits the base plate.

[0019] Furthermore, the connecting assembly includes a protective shell fitted onto the outer surface of the housing to protect the housing and reduce the entry of dust. A locking block is fixedly connected to the bottom of the protective shell, and a limiting groove is formed inside the locking block.

[0020] The snap-fit ​​assembly includes a movable groove inside the base plate. A connecting plate is slidably connected to the inner wall of the movable groove. A connecting rod is fixedly connected to the side of the connecting plate near the snap-fit ​​block. There are two connecting rods in total. A limit rod is slidably connected to the outer surface of the upper connecting rod, and a buckle is slidably connected to the outer surface of the lower connecting rod. A spring is fixedly connected to the left side of both connecting rods.

[0021] The limiting rod and buckle will limit the block after it is inserted into the bottom, preventing it from moving.

[0022] Furthermore, the locking assembly includes a fixing rod fixedly connected to the front of the connecting plate, a connecting rod two slidably connected to the inner wall of the limiting groove, a spring three fixedly connected to the inner wall of the connecting rod two, the other end of the spring three fixedly connected to the inner wall of the fixing rod, a pull rod fixedly connected to the front of the connecting rod two, a locking block fixedly connected to the outer surface of the connecting rod two, and a slot fixedly connected to the front of the base plate, the inner wall of the slot being inserted into the outer surface of the locking block;

[0023] When the protective shell needs to be removed, pull the connecting rod two to disengage the locking block from the slot and pull it to move to the slot on the other side, so that the limiting rod disengages from the buckle and the limiting of the block is released.

[0024] This utility model has the following beneficial effects:

[0025] 1. This utility model uses a locking block. Specifically, when the locking block enters the bottom plate, it first squeezes the limiting rod, causing the limiting rod to move to the right. As the locking block continues to move downward, it simultaneously pushes the buckle to the right. When the locking block reaches the bottom, the two springs return, pushing the limiting rod and the buckle to the left, so that the buckle is above the locking block. At the same time, the limiting rod enters the limiting groove, completing the locking of the protective shell. The installation is simple and quick, and the protective shell protects the box.

[0026] 2. This utility model uses a positioning block. Specifically, the positioning hole is aligned with the positioning rod first, and then the cabinet is pushed into the bottom plate. When the cabinet moves, the positioning block is first squeezed, causing it to move downwards. This causes the positioning block to push the connecting rod and drive the slider to compress the spring. When the back of the cabinet is in contact with the front of the bottom plate, the spring rebounds and pushes the positioning block upwards, allowing it to enter part of the bottom of the cabinet. Then, the cabinet is fixed to the bottom plate with fixing bolts to prevent the cabinet from tilting due to foreign objects between the cabinet and the bottom plate, which would cause differences in the subsequent COB display.

[0027] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0037] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0038] Please see Figures 1-6 As shown, this utility model is a fixing structure for a COB display panel, including a mounting part 1, which is used to install the COB display panel.

[0039] Protective part 2 is installed inside the mounting part 1 and is used to protect the COB display panel;

[0040] In this process, after the COB display panel is installed above the mounting section 1, the protective section 2 blocks the cabling conduit of the COB display panel.

[0041] The mounting section 1 includes an auxiliary component 11, which assists in the installation of the COB display panel; and

[0042] Positioning component 12 is installed inside auxiliary component 11 and is used to position the COB display panel.

[0043] The protective part 2 includes a connecting component 21, which is used to connect to the mounting part 1;

[0044] Snap-fit ​​assembly 22, installed inside auxiliary assembly 11, is used to snap-fit ​​connection assembly 21; and

[0045] Locking component 23 is installed inside auxiliary component 11 and is used to lock the snap-fit ​​component 22;

[0046] In this process, after the connecting component 21 is installed into the auxiliary component 11, the connecting component 21 is snapped into place by the snap-fit ​​component 22, and then the snap-fit ​​component 22 is locked by the locking component 23.

[0047] The auxiliary component 11 includes a base plate 111, the front of which contacts the housing 112, a positioning rod 113 is fixedly connected to the front of the base plate 111, a positioning hole 114 is opened inside the housing 112, the inner wall of the positioning hole 114 is adapted to the outer surface of the positioning rod 113, and a fixing bolt 115 is fixedly connected inside the housing 112.

[0048] The cabinet 112 is positioned by the positioning rod 113 and the positioning hole 114. Then, the cabinet 112 is connected to the base plate 111 by the fixing bolt 115. First, the positioning hole 114 is aligned with the positioning rod 113. Then, the cabinet 112 is pushed into the base plate 111. When the cabinet 112 moves, it will first squeeze the positioning block 125, causing the positioning block 125 to move downward. This pushes the connecting rod 124 to drive the slider 122 to squeeze the spring 123. When the back of the cabinet 112 is in contact with the front of the base plate 111, the spring 123 rebounds and pushes the positioning block 125 upward, so that it enters a part of the bottom of the cabinet 112. Then, the fixing bolt 115 is used to fix the cabinet 112 above the base plate 111 to prevent the cabinet 112 from tilting due to foreign objects between the cabinet 112 and the base plate 111, which would cause differences in the subsequent COB display.

[0049] The positioning component 12 includes a slide groove 121 opened inside the base plate 111. A slider 122 is slidably connected to the inner wall of the slide groove 121. There are two sliders 122. A spring 123 is fixedly connected to one side of the sliders 122 that are close to each other. A connecting rod 124 is rotatably connected to the top of the sliders 122. A positioning block 125 is rotatably connected to the other end of the connecting rod 124.

[0050] The enclosure 112 is positioned using a positioning block 125 to check if it fits snugly against the base plate 111. When the locking block 212 enters the base plate 111, it first presses the limiting rod 226, causing it to move to the right. As the locking block 212 continues to move downward, it simultaneously pushes the latch 224 to the right. When the locking block 212 reaches the bottom, the two springs 225 rebound, pushing the limiting rod 226 and the latch 224 to the left, so that the latch 224 is above the locking block 212. At the same time, the limiting rod 226 enters the limiting groove 213, locking the protective shell 211. This prevents dust from entering the enclosure 112 through the cable tray during use, which could cause short circuits in the components inside the enclosure 112. The installation is also simple and quick.

[0051] The connecting component 21 includes a protective shell 211 fitted onto the outer surface of the housing 112, and a locking block 212 fixedly connected to the bottom of the protective shell 211. A limiting groove 213 is provided inside the locking block 212.

[0052] The snap-fit ​​assembly 22 includes a movable groove 221 opened inside the base plate 111. A connecting plate 222 is slidably connected to the inner wall of the movable groove 221. A connecting rod 223 is fixedly connected to the side of the connecting plate 222 near the snap block 212. There are two connecting rods 223. A limit rod 226 is slidably connected to the outer surface of the upper connecting rod 223. A buckle 224 is slidably connected to the outer surface of the lower connecting rod 223. A spring 225 is fixedly connected to the left side of both connecting rods 223.

[0053] Specifically, after the locking block 212 is inserted into the bottom, the limiting rod 226 and the buckle 224 will limit the locking block 212, preventing it from moving.

[0054] The locking assembly 23 includes a fixing rod 231 fixedly connected to the front of the connecting plate 222, a connecting rod 236 slidably connected to the inner wall of the limiting groove 213, a spring 235 fixedly connected to the inner wall of the connecting rod 236, the other end of the spring 235 fixedly connected to the inner wall of the fixing rod 231, a pull rod 233 fixedly connected to the front of the connecting rod 236, a locking block 234 fixedly connected to the outer surface of the connecting rod 236, and a slot 232 fixedly connected to the front of the base plate 111, with the inner wall of the slot 232 interlocking with the outer surface of the locking block 234.

[0055] When the protective shell 211 needs to be removed, the connecting rod 236 is pulled to disengage the locking block 234 from the slot 232 and pull it to move to the slot 232 on the other side, so that the limiting rod 226 disengages from the buckle 224 and the limiting of the block 212 is released.

[0056] A specific application of this embodiment is as follows: In use, first align the positioning hole 114 with the positioning rod 113, and then push the housing 112 into the base plate 111. When the housing 112 moves, it will first squeeze the positioning block 125, causing the positioning block 125 to move downward, which will push the connecting rod 124 to drive the slider 122 to squeeze the spring 123. When the back of the housing 112 is in contact with the front of the base plate 111, the spring 123 rebounds and pushes the positioning block 125 upward, so that it enters a part of the bottom of the housing 112. Then, the housing 112 is fixed to the base plate 11 by the fixing bolt 115. To prevent foreign objects from causing tilting during the installation of the cabinet 112 and base plate 111, which could result in discrepancies in the subsequent COB display, the COB is inserted into the cabinet 112 after installation. Once installation is complete, the protective shell 211 is placed over the outside of the cabinet 112 from top to bottom, and the locking block 212 is inserted into the base plate 111. When the locking block 212 enters the base plate 111, it first presses the limiting rod 226, causing it to move to the right, simultaneously compressing the second spring 225. As the locking block 212 continues to move downwards, it will... Simultaneously, push the latch 224 to the right and compress the second spring 225. When the latch block 212 moves to the bottom, the two springs 225 rebound, simultaneously pushing the limiting rod 226 and the latch 224 to the left, so that the latch 224 is above the latch block 212. At the same time, the limiting rod 226 will enter the limiting groove 213, completing the locking of the protective shell 211. This prevents dust from entering the cabinet 112 through the cable tray during use, which could cause short circuits due to dust accumulation on the internal components. When it is necessary to disassemble the protective shell 211, pull the lever 233 forward, causing it to move the connecting rod 236. Move the spring 235 and pull it. Then, move the connecting rod 236 to move the locking block 234 so that it disengages from the slot 232. Then, pull the lever 233 towards the center and move the connecting rod 236 and the fixing rod 231 to move. Then, move the fixing rod 231 to move the connecting plate 222. When the connecting plate 222 moves, it will simultaneously move the two connecting rods 223, causing them to pull the buckle 224 and the limit rod 226 to disengage from the block 212. After disengagement, lift the protective shell 211 upwards to remove it.
