Description

Technical Field

[0001] This invention relates to the field of electronic components, and more particularly to an outdoor high-brightness MiniLED backlight module. Background Technology

[0002] MiniLED backlight modules are a new type of LED module that uses tiny LED beads as the light source. They have high brightness, high dynamic range display, and high-precision local dimming, which are significant advantages over traditional LED modules. In normal use, multiple backlight modules are combined and spliced ​​to form a large display screen. However, due to the large number of backlight modules, it is inevitable that a single module will fail and not work. If the faulty module happens to be located in the middle of multiple modules, where the modules are seamlessly spliced, it will be inconvenient to disassemble the faulty module.

[0003] In addition, when disassembling a single faulty module located in the middle of multiple backlight modules, there are usually two methods: one is to use a suction cup to adhere to the surface of the faulty module and pull it off the bracket; the other is to squeeze the adjacent modules of the faulty module inward, so that the faulty module is misaligned with the adjacent modules, and then remove the faulty module from the bracket. The former requires the use of suction cup tools, and some faulty modules are located at heights that require the use of ladders or other tools to reach them. Using a suction cup to adhere to and pull out the faulty module requires applying pulling force, and the user is prone to losing their balance and falling at the moment of pulling out the faulty module. The latter requires strong pressure on the normal module, which can easily damage the adjacent normal modules. Summary of the Invention

[0004] To overcome the drawbacks of using suction cups to remove faulty modules from high places, which can cause users to lose their balance and fall off ladders, and the risk of damaging adjacent normal modules when manually removing them, this invention provides an outdoor high-brightness MiniLED backlight module.

[0005] The technical solution is as follows: an outdoor high-brightness MiniLED backlight module, including an LED panel and a fixed frame; the fixed frame is fixedly connected to the back of the LED panel; it also includes a pressing and pushing component, a magnet, a sliding sleeve, and a sliding rod; several pressing and pushing components for pushing the LED panel and the fixed frame to move are connected to the fixed frame; each pressing and pushing component is connected to a magnet; the magnet consists of an outer magnetic ring and an inner magnetic block; the magnetic block is fixedly connected to a sliding sleeve; the sliding sleeve is connected to the corresponding pressing and pushing component; each pressing and pushing component is connected to a sliding rod; the sliding rod passes through the corresponding sliding sleeve and is slidably connected to it; one end of the sliding rod passing through the sliding sleeve is fixedly connected to a limiting piece.

[0006] As an improvement to the above solution, the pressing and pushing assembly includes a slide cylinder and a slider; the slide cylinder is connected to the fixed frame; the slide cylinder is horizontally arranged, and the opening of the slide cylinder faces away from the LED panel; the slide rod is fixedly connected to the slide cylinder; a locking rod is rotatably connected inside the slide cylinder; a slider is slidably connected inside the slide cylinder; a slide sleeve is slidably connected to the slider; an elastic element is fixedly connected between the slide cylinder and the slider; a locking groove is provided on the slider; the locking groove consists of two V-shaped parts and two horizontal parts; a top block is provided between the slider and the left V-shaped part; the locking rod moves within the locking groove; the side of the slider away from the slide cylinder is fixedly connected to the magnetic ring; a receiving groove is provided on the side of the slider away from the slide cylinder; the receiving groove has the same shape as the magnetic block.

[0007] As an improvement to the above solution, it also includes a rotating shaft; the LED panel is a flexible circuit board; the fixing frame is made of rubber, and several bending grooves are opened on the side of the fixing frame away from the LED panel; several movable grooves are opened on the fixing frame; each slide cylinder is located in the corresponding movable groove; two rotating shafts are fixedly connected to the slide cylinder; the rotating shafts are rotatably connected to the fixing frame.

[0008] As an improvement to the above solution, it also includes limiting rods; two limiting holes are opened on the upper and lower surfaces of the fixed frame; two U-shaped limiting rods are detachably connected to the fixed frame; the limiting rods are adapted to the limiting holes.

[0009] As an improvement to the above solution, the horizontal section of the limiting rod is made of rubber; the two vertical sections of the limiting rod are made of metal.

[0010] As an improvement to the above scheme, the end of the vertical section of the limiting rod is tapered.

[0011] As an improvement to the above solution, the locking rod has a circular cross-section.

[0012] As an improvement to the above scheme, the inner circumferential surface of the magnetic ring and the outer circumferential surface of the magnetic block are smooth surfaces.

[0013] As an improvement to the above solution, a connecting strip is also included; a connecting strip for uniformly transmitting the extrusion force is connected between every two adjacent upper and lower slide cylinders; the connecting strip is rotatably connected to the shaft of the corresponding slide cylinder.

[0014] As an improvement to the above solution, the connecting strip is made of low-plasticity metal.

[0015] Beneficial effects: This invention enables the faulty module to protrude from the adjacent module by pressing, allowing the user to directly grab the faulty module for disassembly without the need for tools such as suction cups, which is convenient and quick. At the same time, it avoids pressing other normal modules and thus avoids damaging the normal modules.

[0016] The magnet is divided into two parts: a magnetic ring and a magnetic block. When the user presses the LED panel to extend the module for disassembly, the magnetic block detaches from the mounting bracket, thereby reducing the overall area of ​​the magnet adsorbed on the mounting bracket. This reduces the stability of the module adsorbed on the mounting bracket, making it easier for the user to remove the module from the mounting bracket. At the same time, the magnetic ring keeps the module connected to the mounting bracket, preventing the module from falling directly and pulling on the connected wires, which could damage the wiring.

[0017] When disassembling modules installed in both convex and concave configurations, press the LED panel in sections to make the module protrude in sections. The limiting rods restrict the shape of the LED panel and the fixing frame, preventing the curved LED panel and fixing frame from deforming on both sides and coming into contact with adjacent modules, creating frictional resistance and affecting the outward extension of the LED panel and fixing frame.

Detailed Implementation

[0033] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0034] Example 1

[0035] like Figures 1-13 As shown, an outdoor high-brightness MiniLED backlight module includes an LED panel 1 and a fixing frame 2; the fixing frame 2 is fixedly attached to the back of the LED panel 1; a control circuit, several MiniLED beads and a connector are provided on the back of the LED panel 1.

[0036] It also includes a pressing and pushing assembly, a magnet 5, a sliding sleeve 6, and a sliding rod 7; six pressing and pushing assemblies are connected to the fixed frame 2 in a matrix arrangement; each pressing and pushing assembly is connected to a magnet 5; the magnet 5 consists of an outer magnetic ring 51 and an inner magnetic block 52; the magnetic block 52 is fixedly connected to the sliding sleeve 6; the sliding sleeve 6 is connected to the corresponding pressing and pushing assembly; each pressing and pushing assembly is connected to a sliding rod 7; the sliding rod 7 passes through the corresponding sliding sleeve 6 and is slidably connected to it; one end of the sliding rod 7 passing through the sliding sleeve 6 is fixedly connected to a limiting piece.

[0037] The pressing and pushing assembly includes a slide cylinder 3 and a slider 4; the slide cylinder 3 is connected to the fixed frame 2; the slide cylinder 3 is horizontally arranged, and the opening of the slide cylinder 3 faces away from the LED panel 1; the slide rod 7 is fixedly connected to the slide cylinder 3; a locking rod 31 is rotatably connected inside the slide cylinder 3; the slider 4 is slidably connected inside the slide cylinder 3; the slide sleeve 6 is slidably connected to the slider 4; an elastic element 32 is fixedly connected between the slide cylinder 3 and the slider 4; the elastic element 32 is a spring; a locking groove 41 is provided on the slider 4; the locking groove 41 is composed of two V-shaped parts 42 and two horizontal parts 44; a top block 43 is provided between the slider 4 and the left V-shaped part 42; the locking rod 31 moves within the locking groove 41; the side of the slider 4 away from the slide cylinder 3 is fixedly connected to the magnetic ring 51; a receiving groove 45 is provided on the side of the slider 4 away from the slide cylinder 3; the receiving groove 45 has the same shape as the magnetic block 52.

[0038] It also includes a rotating shaft 201; the LED panel 1 is a flexible circuit board; the fixing frame 2 is made of rubber, and the surface of the fixing frame 2 away from the LED panel 1 has several bending grooves; the fixing frame 2 has six movable grooves 21; each slide cylinder 3 is located in the corresponding movable groove 21; the slide cylinder 3 is fixedly connected to two symmetrically distributed rotating shafts 201 along the vertical line; the rotating shafts 201 are rotatably connected to the fixing frame 2.

[0039] It also includes a limiting rod 202; two limiting holes 22 are opened on the upper and lower surfaces of the fixing frame 2; two U-shaped limiting rods 202 are detachably connected to the fixing frame 2; the limiting rods 202 are adapted to the limiting holes 22.

[0040] The horizontal section of the limiting rod 202 is made of rubber; both vertical sections of the limiting rod 202 are made of metal; the horizontal rubber section can change the distance between the two metal vertical sections, making it easier for the user to insert the vertical section of the limiting rod 202 into the limiting hole 22.

[0041] The vertical end of the limiting rod 202 is tapered, making it easy to insert into the limiting hole 22.

[0042] The locking rod 31 has a circular cross-section; this reduces the frictional force when the locking rod 31 moves within the locking groove 41, ensuring smooth operation.

[0043] The inner circumferential surface of the magnetic ring 51 and the outer circumferential surface of the magnetic block 52 are smooth surfaces; this reduces the frictional resistance between the magnetic ring 51 and the magnetic block 52.

[0044] Currently, there are generally two methods for disassembling a single faulty module located in the middle of multiple backlight modules. One is to use a suction cup to adhere to the surface of the faulty module and remove it from the bracket. The other is to squeeze the adjacent modules of the faulty module inward, causing the faulty module to be misaligned with the adjacent modules, and then pry the faulty module off the bracket. The former requires the use of a suction cup tool, and some faulty modules are located at heights that require the use of ladders or other tools to reach them. Using a suction cup to pull out the faulty module requires applying pulling force, and the user is prone to losing their balance and falling at the moment of pulling out the faulty module. The latter requires strong pressure on the normal module, which can easily damage the adjacent normal modules.

[0045] Therefore, the present invention provides an outdoor high-brightness MiniLED backlight module, which aims to solve the above-mentioned problems.

[0046] by Figure 6 Using the viewing reference, the side where the mounting bracket 1111 is labeled is the left side, and the side where the LED panel 1 is labeled is the right side. In the initial state of the pressing and pushing assembly of the present invention, the slider 4 is retracted into the slide cylinder 3, the locking rod 31 is located in the V-shaped part 42 on the left side of the locking groove 41, and the elastic element 32 is in a compressed state; the magnetic ring 51 and the magnetic block 52 are flush; when installing the present invention, wires are provided between the mounting brackets 1111. First, the wires are connected to the connector on the back of the LED panel 1. Then, the user installs the LED panel 1 on the mounting bracket 1111, and the present invention is fixed on the mounting bracket 1111 by all the magnets 5. Then, in the same way, multiple present inventions are installed according to the required coverage area, and they are arranged in a manner similar to each other. Figure 1 The diagram shows a seamless splicing, which allows multiple units of this invention to be combined and installed to form a large display panel.

[0047] When it is necessary to disassemble a single faulty module located in the middle, the user should place both hands on the front of the LED panel 1 of the faulty module and gently press the LED panel 1 towards the mounting bracket 1111. Figure 6As shown, the LED panel 1 presses against the fixing frame 2, and the fixing frame 2 presses against the slide cylinder 3 via the rotating shaft 201. The slide cylinder 3 presses against the corresponding elastic element 32, and at the same time, the slide cylinder 3 drives the locking rod 31 to move to the left. The locking rod 31 contacts the top block 43 and is guided by it to move into the horizontal part 44. It should be noted that during the movement of the sliding cylinder 3 and the locking rod 31, the locking rod 31 moves according to the shape of the locking groove 41, and the locking rod 31 will rotate adaptively relative to the slide cylinder 3. Afterwards, the user releases the pressure on the LED panel 1, the elastic element 32 extends, pushes the slide cylinder 3, and the slide cylinder 3 pushes the LED panel 1 and the fixing frame 2 to move away from the mounting bracket 1111. The slide cylinder 3 will drive the locking rod 31 to move to the right in the horizontal part 44, and then the locking rod 31 moves from the V-shaped part 42 on the left side of the locking groove 41 to the V-shaped part 42 on the right side. Then the locking rod 31 is restricted by the V-shaped part 42 on the right side, thereby stopping the movement of the slide cylinder 3. Figure 7 As shown, at this time, the slider 4 is still connected to the mounting bracket 1111 by the attraction of the magnet 5, and the slider 3 drives the LED panel 1 and the fixing frame 2 away from the mounting bracket 1111, and finally as shown... Figure 11 As shown, the LED panel 1 and fixing frame 2 of the faulty module to be disassembled protrude from the adjacent module. At this time, the user can grasp the protruding outer edge of the LED panel 1 and fixing frame 2 to pull the faulty module off the mounting bracket 1111, so that the magnet 5 and the mounting bracket 1111 are released from attraction. Then, the user unplugs the power cord from the connector of the faulty module, replaces the new module, and installs the new module on the mounting bracket 1111 according to the aforementioned installation steps to complete the disassembly and replacement of the faulty module. In summary, by pressing the faulty module to protrude from the adjacent module, it is easy for the user to grasp the faulty module for disassembly without the need for tools such as suction cups, and there is no need to press other normal modules, thus avoiding damage to normal modules.

[0048] Furthermore, since there are multiple magnets 5, users still need to use considerable force when disassembling and pulling out the module. When the magnet 5 separates from the mounting bracket 1111, the user may not have time to release the force and could easily fall, while simultaneously pulling on the wires connected to the LED panel 1, causing the wires to break. If the user presses on the LED panel 1 to extend the entire module, and at the same time the magnet 5 separates from the mounting bracket 1111, the module will fall downwards if the user does not catch it in time, pulling on the connected wires and causing damage to the wiring.

[0049] Therefore, in this invention, the magnet 5 is divided into two parts: a magnetic ring 51 and a magnetic block 52, so as to... Figure 6 Using the direction reference, when the user presses LED panel 1, causing the module to extend to the right, as... Figure 7As shown, as the slide cylinder 3 moves to the right and moves away from the slider 4, the slide cylinder 3 will drive the slide rod 7 to move to the right. The slide rod 7 first slides to the right within the slide sleeve 6 until the limiting piece of the slide rod 7 contacts the right side wall of the slide sleeve 6, which will drive the slide sleeve 6 to move to the right. The slide sleeve 6 will then drive the magnetic block 52 to move to the right, thereby causing the magnetic block 52 to detach from the mounting bracket 1111 and enter the receiving groove 45. Thus, only the magnetic ring 51 remains attached to the mounting bracket 1111, reducing the area of ​​the magnet 5 and the mounting bracket 1111, thereby reducing the stability of the module attached to the mounting bracket 1111. This makes it easier for the user to remove the module from the mounting bracket 1111, while the magnetic ring 51 keeps the module connected to the mounting bracket 1111, preventing the module from falling directly and pulling on the connected wires, which could damage the wiring.

[0050] To accommodate the curved mounting surface, in the prior art, the LED panel 1 and the fixing frame 2 are made of flexible material that can be bent and deformed. Since the initial shape of the LED panel 1 and the fixing frame 2 is straight, when the present invention is installed in a curved shape, and the sliding cylinder 3 causes the LED panel 1 and the fixing frame 2 to extend to the right by compression, the LED panel 1 and the fixing frame 2 will tend to return to a straight shape due to the plasticity of the material itself. As a result, the LED panel 1 and the fixing frame 2 undergo slight deformation to the front and rear sides, and come into contact with the adjacent modules on the front and rear sides, thereby forming frictional resistance and affecting the outward extension of the LED panel 1 and the fixing frame 2.

[0051] Therefore, as Figure 13 As shown, the curved surface has two installation configurations: an outward convexity on the left and an inward concavity on the right. It should be noted that each pressing and pushing component of this invention can work independently.

[0052] First, taking the outward convex case as an example: The user first presses the most protruding position in the center of the front of the LED panel 1 to the left, causing the corresponding slide cylinder 3 in the center of the fixing frame 2 to be pressed and squeeze the elastic element 32. After the slide cylinder 3 forces the locking rod 31 to move and unlock, the user releases the pressing pressure, and the slide cylinder 3 moves to the right. The slide cylinder 3 pushes the center of the LED panel 1 and the fixing frame 2 to the right, thereby increasing the outward convexity of the center of the LED panel 1 and the fixing frame 2. The front and rear sides of the LED panel 1 and the fixing frame 2 are pulled towards the center and disengage from the adjacent modules, thus avoiding frictional resistance. Then, the user presses the front and rear sides of the LED panel 1, causing the corresponding slide cylinder 3 to extend and push the front and rear sides of the LED panel 1 and the fixing frame 2 to convex, so that the LED panel 1 and the fixing frame 2 as a whole protrude from the other modules. Then, the user grabs the protruding position of the LED panel 1 and the fixing frame 2 and removes it from the mounting bracket 1111.

[0053] Taking the recessed case as an example: The user first presses the front and back sides of the LED panel 1. At this time, as shown... Figure 13As shown on the right, the magnets 5 on the front and rear sides of the fixing frame 2 are tilted toward the middle of the fixing frame 2, and the slide cylinder 3 is aligned with the magnets 5 on the same axis. When the slide cylinders 3 on the front and rear sides extend, they press the LED panel 1 and the front and rear sides of the fixing frame 2 toward the middle, thereby causing the front and rear sides of the LED panel 1 and the fixing frame 2 to disengage from the adjacent modules and thus avoid frictional resistance from contact with the adjacent modules. Then, the user presses the middle of the LED panel 1, causing the slide cylinder 3 in the middle of the fixing frame 2 to extend and push the middle of the LED panel 1 and the fixing frame 2 to the right. Then, the user grabs the LED panel 1 and the fixing frame 2 and removes them from the mounting bracket 1111.

[0054] In addition, when the LED panel 1 and the fixing frame 2 are installed or removed in an arc shape, the LED panel 1 and the fixing frame 2 deform, which will cause the magnet 5 to shift, affecting the stability of the magnet 5 adsorbed on the mounting bracket 1111. Therefore, the slide cylinder 3 and the slider 4 of the same pressing and pushing component are both located in the movable groove 21, and the slide cylinder 3 is rotatably connected to the fixing frame 2 through the rotating shaft 201. Thus, when the fixing frame 2 is in an arc shape, the slide cylinder 3 can rotate relative to the fixing frame 2, thereby driving the slider 4 and the magnet 5, so that the adsorption surface of the magnet 5 can face the mounting bracket 1111, which has good adaptability and maintains stability. Moreover, the slide cylinder 3 does not contact the wall of the movable groove 21, and the deformation of the fixing frame 2 will not cause the slide cylinder 3 and related parts to deflect.

[0055] In both the convex and concave cases described above, the LED panel 1 and the fixing frame 2 protrude from the other modules in an arc shape, but the protrusion distance is relatively short. Users can only hold the LED panel 1 and the fixing frame 2 with their fingertips, which is inconvenient for applying force. Therefore, when the slide cylinder 3 extends and changes the degree of convexity or concavity of the LED panel 1 and the fixing frame 2, the limiting holes 22 on the upper and lower sides of the fixing frame 2 will be exposed. Then, the user inserts the two limiting rods 202 into the two limiting holes 22 on the upper side and the two limiting holes 22 on the lower side of the fixing frame 2, respectively. The user then applies force through the limiting rods 202 to facilitate the removal of the module. In addition, after the limiting rods 202 are inserted into the limiting holes 22, the fixing frame 2 is fixed by the limiting rods 202, which fixes the current shape of the more protruding LED panel 1 and the fixing frame 2, preventing them from returning to their original shape or deforming, and preventing them from contacting the side of the adjacent module and causing obstruction.

[0056] Example 2

[0057] Based on Example 1, such as Figures 4-7 and Figure 14 As shown, it also includes a connecting strip 301; a connecting strip 301 is connected between every two adjacent upper and lower slide cylinders 3; the connecting strip 301 is rotatably connected to the rotating shaft 201 of the corresponding slide cylinder 3, so that when the slide cylinder 3 rotates relative to the fixed frame 2 through the rotating shaft 201, it does not drive the connecting strip 301 to rotate, thus avoiding the connecting strip 301 from restricting the rotation of the slide cylinder 3.

[0058] The connecting bar 301 is made of low-plasticity metal; it has slight deformation capability to ensure that the pressure is evenly transmitted to the corresponding two sliding cylinders 3.

[0059] When the user presses the LED panel 1, forcing the pressing and pushing components to unlock, causing the slide cylinder 3 to extend the LED panel 1 and the fixing frame 2 away from the mounting bracket 1111, the LED panel 1 is a flexible circuit board and the fixing frame 2 is made of rubber, both of which have flexible properties. Since the pressing and pushing components are located on the back of the LED panel 1, the user cannot accurately see the location of each pressing and pushing component. As a result, when the user presses the LED panel 1, the flexible LED panel 1 and the fixing frame 2 undergo slight deformation, causing uneven pressure transmission. This prevents the corresponding upper and lower slide cylinders 3 from receiving the same pressure simultaneously, causing some slide cylinders 3 to not move. The LED panel 1 and the fixing frame 2 extend unevenly to the right, with some edges not exposed. The user cannot fully grasp the unevenly extended LED panel 1 and the fixing frame 2, making disassembly difficult. If the user presses a second time to extend the slide cylinders 3 that have not yet extended, it may cause the already extended slide cylinders 3 to retract again, still resulting in the LED panel 1 and the fixing frame 2 only extending outward on one side.

[0060] Therefore, a connecting strip 301 is connected between the two sliding cylinders 3 in each vertical row. When the user presses the LED panel 1, the pressing pressure is mainly concentrated on the surface of the LED panel 1 corresponding to the connecting strip 301. When the user squeezes the LED panel 1, most of the squeezing force will be applied to the connecting strip 301. The connecting strip 301 is made of low-plasticity metal material, which ensures that the pressure can be effectively and evenly transmitted to the two sliding cylinders 3 in the corresponding vertical row. This allows both sliding cylinders 3 to receive sufficient pressing pressure from the compression elastic element 32. As a result, the two sliding cylinders 3 move synchronously, driving the locking rod 31 to move in the locking groove 41, so that the two sliding cylinders 3 can be unlocked and extended. This prevents some sliding cylinders 3 from not being able to be pressed and thus not moving. The LED panel 1 and the fixing frame 2 extend unevenly to the right, with some edges not exposed. This makes it difficult for the user to fully grasp the unevenly extended LED panel 1 and the fixing frame 2, making disassembly difficult.

[0061] The above embodiments are merely preferred embodiments of the present invention and are not intended to limit the scope of the present invention. Therefore, all equivalent changes made to the content described in the claims of the present invention should be included within the scope of the claims of the present invention.
