Description

Technical Field

[0001] This utility model belongs to the field of controller technology, and in particular relates to a multi-interface LCD TV dynamic backlight controller. Background Technology

[0002] The LCD TV dynamic backlight controller can automatically adjust the backlight brightness according to the content of the TV screen. The multi-interface LCD TV dynamic backlight controller is equipped with a variety of interfaces, including common interfaces such as HDMI (High Definition Multimedia Interface), USB (Universal Serial Bus), and VGA (Video Graphics Array), as well as some dedicated interfaces for specific devices. This allows the dynamic backlight controller to connect to various external devices such as computers, game consoles, and Blu-ray players, making it convenient for users to play different types of content and enjoy the visual enhancement brought by dynamic backlight.

[0003] Because multi-interface LCD TV dynamic backlight controllers have multiple wires connected, and traditional multi-interface LCD TV dynamic backlight controllers do not restrain these multiple wires after connection, the messy and random placement of these wires significantly reduces the overall aesthetics of the device. At the same time, the messy placement of multiple wires can easily lead to overheating or short circuits due to the close proximity of the wires, which may even cause a fire in severe cases. Therefore, a multi-interface LCD TV dynamic backlight controller is proposed. Utility Model Content

[0004] The purpose of this invention is to provide a multi-interface LCD TV dynamic backlight controller. By setting up a cable management assembly, specifically pulling a lever two causes a push rod to move a limiting rod two. Simultaneously, the limiting rod two compresses a spring two. When the user pushes the baffle downwards, the spring two generates a certain rebound force, causing the limiting rod two to insert into the bottom hole. The user then embeds multiple wires into several elastic clips for fixation, achieving a binding effect on the connecting wires and avoiding messy wiring. This solves the problem that traditional multi-interface LCD TV dynamic backlight controllers do not bind multiple wires after connection, resulting in messy and haphazard placement of the wires, significantly reducing the overall aesthetics of the device. Furthermore, messy placement of multiple wires can easily lead to overheating or short circuits due to excessively close proximity, potentially causing a fire in severe cases.

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

[0006] This utility model relates to a multi-interface LCD TV dynamic backlight controller, comprising a main frame mechanism, the main frame mechanism including a controller body, the controller body having several heat dissipation holes on both the left and right sides, an interface plate on the front of the controller body, and dustproof components on the left and right sides of the top of the controller body. The dustproof component on the left side includes a limiting frame. A cable management assembly is provided on the front of the interface plate, the cable management assembly including a baffle, the baffle having several openings inside, each of the openings containing an elastic clip. Slide rails are fixedly connected to the left and right sides of the front of the controller body, and the two slide rails are slidably connected to the left and right sides of the baffle. The baffle has two holes on both the left and right sides. Each of the slide rails has a limiting rod slidably connected to its top. A support sleeve is fixedly connected to the top of the left side of the slide rail. The inner wall of the support sleeve is slidably connected to the outer surface of the limiting rod. A push rod is slidably connected to the side of the support sleeve away from the slide rail. The push rod passes through the support sleeve and extends to the inside and left side. A pull-torque is provided on the left side of the support sleeve. Pulling the pull-torque causes the limiting rod to move through the push rod. At the same time, when the limiting rod moves, it will compress the spring. When the user pushes the baffle downward, the spring will generate a certain rebound force and drive the limiting rod to insert into the hole at the bottom. Then the user can embed multiple wires into several elastic clips for fixation, achieving the binding effect of the wires and avoiding messy wire placement.

[0007] Furthermore, the inner surface of the pull-torque two is fixedly connected to the outer surface of the push rod, and the outer surface of the push rod is fitted with a spring two. The left side of the spring two is fixedly connected to the left side of the inner wall of the support sleeve, and the side of the spring two away from the pull-torque two is fixedly connected to the left side of the limiting rod two. The side of the limiting rod two away from the push rod is inserted into the hole. The top of several inner walls of the support sleeves are fixedly connected to limiting brackets, and the inside of several limiting brackets is rotatably connected to the top of the elastic clips through pins. The bottom of the limiting frame is fixedly connected to the top of the controller body. When the pull-torque two is released, the spring two will generate a certain rebound force and drive the limiting rod two to reset. At the same time as the limiting rod two resets, it will insert into the hole at the bottom. At this time, the limiting rod two will again limit and fix the baffle through the hole at the bottom. Then the user can insert multiple wires into several elastic clips for fixation.

[0008] Furthermore, a filter screen is provided between the controller body and several heat dissipation holes. A fixing block is fixedly connected to the top of the filter screen. A limiting hole is opened inside the fixing block. A limiting rod is slidably connected inside the limiting frame. The limiting rod passes through the limiting frame and extends to the inside and front of the limiting frame. When the filter screen needs to be replaced after the device has been used for a period of time, the user can pull the first pull to remove the filter screen. During installation, the first pull is also pulled to move the limiting rod. When the limiting rod moves, it will slide inside the limiting frame. At the same time, when the limiting rod moves, it will move the limiting ring together. When the limiting ring moves, it will compress the spring. The spring will contract and store force due to the limiting effect of the inner wall of the limiting frame. Then, the user puts the fixing block into the limiting frame and puts the filter screen into the reserved slot between the heat dissipation hole and the controller body.

[0009] Furthermore, the limiting frame has a pull-twist mechanism on its front side, which is fixedly connected to the outer surface of the limiting rod. A partition is fixedly connected to the inner wall of the limiting frame, and the partition is slidably connected to the outer surface of the limiting rod. A spring is sleeved on the outer surface of the limiting rod, with its front fixedly connected to the front of the inner wall of the limiting frame. A limiting ring is fixedly connected to the side of the spring away from the pull-twist mechanism, with its interior fixedly connected to the outer surface of the limiting rod. The back of the limiting ring contacts the front of the partition. The side of the limiting rod's outer surface away from the pull-twist mechanism is inserted into the limiting hole. When the pull-twist mechanism is released, the spring will generate a certain rebound force and drive the limiting rod to reset. As the limiting rod resets, it will insert into the limiting hole, thus limiting and fixing the fixing block through the limiting hole. This completes the installation and replacement of the filter.

[0010] This utility model has the following beneficial effects:

[0011] 1. This utility model, by setting up a wire harness assembly, specifically involves pulling the pull rod two to drive the limit rod two to move through the push rod. At the same time, when the limit rod two moves, it will compress the spring two. Then, the user pushes the baffle downward, at which point the spring two will generate a certain rebound force and drive the limit rod two to insert into the hole at the bottom. Then, the user can embed multiple wires into several elastic clips for fixation, achieving the binding effect of the wires, avoiding messy wire placement, avoiding overheating and short circuits caused by wires being too close together, and greatly improving the aesthetics of the equipment.

[0012] 2. This utility model incorporates a dustproof component. Specifically, pulling the pull knob compresses the spring via a limiting rod and a limiting ring. The spring, constrained by the inner wall of the limiting frame, contracts and stores force. The user then places the fixing block inside the limiting frame and simultaneously inserts the filter into the pre-drilled slot between the heat dissipation hole and the controller body. Releasing the pull knob causes the spring to rebound, pushing the limiting rod into the limiting hole. The limiting rod then secures the fixing block through the limiting hole, completing the installation and replacement of the filter. This timely filter replacement significantly improves the dustproof effect of the equipment, reduces malfunctions caused by excessive dust inside the controller body, and greatly enhances the stability of the equipment.

Detailed Implementation

[0022] 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 of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Please see Figure 1-5As shown, this utility model is a multi-interface LCD TV dynamic backlight controller, including a main frame mechanism 1. The main frame mechanism 1 includes a controller body 111. The controller body 111 has several heat dissipation holes 112 on both the left and right sides. An interface plate 113 is provided on the front of the controller body 111. Dustproof components 2 are provided on the left and right sides of the top of the controller body 111. The dustproof component 2 on the left side includes a limiting frame 211. A cable management component 3 is provided on the front of the interface plate 113. The cable management component 3 includes a baffle 311. Several openings 312 are provided inside the baffle 311. Elastic clips 315 are provided inside each of the openings 312. Slide rails 313 are fixedly connected to the left and right sides of the front of the controller body 111. Both slide rails 313 are slidably connected to the left and right sides of baffle 311. Two holes 316 are provided on the left and right sides of baffle 311. Limiting rods 317 are slidably connected to the top of the interior of both slide rails 313. A support sleeve 321 is fixedly connected to the top of the left side of the slide rail 313. The inner wall of the support sleeve 321 is slidably connected to the outer surface of the limiting rod 317. A push rod 319 is slidably connected to the side of the support sleeve 321 away from the slide rail 313. The push rod 319 passes through the support sleeve 321 and extends to the interior and left side. A pull torque 320 is provided on the left side of the support sleeve 321. Pulling the pull torque 320 causes the limiting rod 317 to move via the push rod 319. Simultaneously, when the limiting rod 317 moves... The spring 318 is compressed, and then the user pushes the baffle 311 downwards. The spring 318 then generates a certain rebound force, causing the limiting rod 317 to insert into the bottom hole 316. The user then inserts multiple wires into several elastic clips 315 for fixation, achieving a binding effect on the wires, preventing messy wiring, and avoiding overheating and short circuits caused by excessively close wires. This also significantly improves the aesthetics of the equipment. The pull-torque 320 is fixedly connected to the outer surface of the push rod 319. The outer surface of the push rod 319 is fitted with the spring 318. The left side of the spring 318 is fixedly connected to the left side of the inner wall of the support sleeve 321. The side of the spring 318 away from the pull-torque 320 is connected to the limiting rod. The left side of the second 317 is fixedly connected. The side of the second 317 away from the push rod 319 is inserted into the hole 316. The top of the inner wall of several support sleeves 321 is fixedly connected to the limit bracket 314. The inside of several limit brackets 314 is rotatably connected to the top of the elastic clamp 315 through pins. The bottom of the limit frame 211 is fixedly connected to the top of the controller body 111. A filter screen 212 is provided between the controller body 111 and several heat dissipation holes 112. The top of the filter screen 212 is fixedly connected to the fixing block 219. The fixing block 219 has a limit hole 218 inside. The limit rod 214 is slidably connected inside the limit frame 211. The limit rod 214 passes through the limit frame 211 and extends to the inside and front of the limit frame 211.Pulling the first pull knob 213 causes the limiting rod 214 to drive the limiting ring 215 to compress the spring 216. The spring 216, limited by the inner wall of the limiting frame 211, contracts and stores force. Then, the user places the fixing block 219 inside the limiting frame 211 and simultaneously places the filter screen 212 into the reserved slot between the heat dissipation hole 112 and the controller body 111. The user then releases the first pull knob 213. The spring 216 then generates a certain rebound force, causing the limiting rod 214 to insert into the limiting hole 218. The limiting rod 214 then limits and fixes the fixing block 219 through the limiting hole 218. This completes the installation and replacement of the filter screen 212. Timely replacement of the filter screen 212 significantly improves the dustproof effect of the equipment and reduces dust accumulation inside the controller body 111. To address the malfunctions caused by excessive dust, this device significantly improves operational stability. The limiting frame 211 has a pull-torque 213 on its front side, which is fixedly connected to the outer surface of the limiting rod 214. A partition 217 is fixedly connected to the inner wall of the limiting frame 211, and the partition 217 is slidably connected to the outer surface of the limiting rod 214. A spring 216 is fitted onto the outer surface of the limiting rod 214, with its front fixedly connected to the front of the inner wall of the limiting frame 211. A limiting ring 215 is fixedly connected to the side of the spring 216 away from the pull-torque 213, with its interior fixedly connected to the outer surface of the limiting rod 214. The back of the limiting ring 215 contacts the front of the partition 217. The side of the limiting rod 214 away from the pull-torque 213 is inserted into the limiting hole 218.

[0024] A specific application of this embodiment is as follows: In use, the user first lifts the baffle 311 upwards. At this time, the limiting rod 317 will limit and fix the baffle 311 through the top hole 316. Then, the user connects multiple wires through the interface plate 113. Afterwards, the user pulls the pull knob 320, causing the push rod 319 to move. When the push rod 319 moves, it slides inside the support sleeve 321. Simultaneously, the movement of the push rod 319 causes the limiting rod 317 to move, at which point the limiting rod 317 disengages from the hole 316. Simultaneously, the movement of the limiting rod 317... When spring 318 is compressed, it contracts and stores force due to the limiting effect of the inner wall of the support sleeve 321. Then, the user pushes the baffle 311 downwards and releases the pull-twist mechanism 320. Spring 318 then generates a certain rebound force, causing the limiting rod 317 to reset. As the limiting rod 317 resets, it inserts into the bottom hole 316, which then again limits and fixes the baffle 311. Finally, the user inserts multiple wires into several elastic clips 315 for fixation, thus achieving... The cable management system effectively binds the wires, preventing messy wiring and overheating / short circuits caused by excessively close wires. When the filter 212 needs replacement after a period of use, the user can easily remove it by pulling the lever 213. During installation, pulling the lever 213 also moves the limiting rod 214, which slides within the limiting frame 211. This movement also moves the limiting ring 215, which in turn compresses the spring 216. 16 will retract and store force due to the limiting effect of the inner wall of the limiting frame 211. At this time, the user puts the fixing block 219 into the limiting frame 211 and puts the filter screen 212 into the reserved slot between the heat dissipation hole 112 and the controller body 111. Then the user releases the pull knob 213. At this time, the spring 216 will generate a certain rebound force and drive the limiting rod 214 to reset. When the limiting rod 214 resets, it will insert into the limiting hole 218. The limiting rod 214 then limits and fixes the fixing block 219 through the limiting hole 218. At this time, the installation and replacement of the filter screen 212 are completed.
