Description

Technical Field

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

[0002] A MiniLED backlight module is a new type of LED module that uses tiny-sized LED beads as the light source. It has properties such as high brightness, high dynamic range display, and high-precision local dimming, and has obvious advantages compared with traditional LED modules. During normal use, a large display screen is formed by combining and splicing multiple backlight modules. Since there are a large number of backlight modules, it is inevitable that a single module fails to work. And if the faulty module is exactly in the middle position of multiple modules and the modules are seamlessly spliced, it is inconvenient to disassemble the faulty module.

[0003] In addition, when disassembling a single faulty module in the middle of multiple backlight modules, there are usually two methods. One is to adsorb the surface of the faulty module with a suction cup and pull out the module from 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 buckle the faulty module from the bracket. The former requires the use of a suction cup tool, and for some faulty modules at a certain height, tools such as ladders are needed to reach. When using the suction cup to adsorb and pull out the faulty module, a pulling force needs to be applied. At the moment of pulling out the faulty module, the user is prone to losing balance and falling. The latter requires strong pressing on the normal modules, which is likely to cause damage to the adjacent normal modules. Summary of the Invention

[0004] In order to overcome the disadvantages that when manually removing a faulty module at a high place by adsorbing and pulling it out with a suction cup tool, the user is prone to losing balance and falling from the ladder, and when pressing the adjacent normal modules during manual removal, it is likely to cause damage to the adjacent normal modules, the present invention provides an outdoor high-brightness MiniLED backlight module.

[0005] The technical solution is as follows: An outdoor high-brightness MiniLED backlight module includes an LED panel and a fixing frame; the fixing frame is fixedly connected to the back of the LED panel; it further 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 fixing frame to move are connected to the fixing 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 the 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 is inserted through the corresponding sliding sleeve and is slidably connected thereto; a limiting piece is fixedly connected to one end of the sliding rod inserted into the sliding sleeve.

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

[0007] As an improvement to the above solution, it further includes a rotating shaft; the LED panel is a flexible circuit board; the fixed frame is made of rubber, and a plurality of bending grooves are formed on the surface of the fixed frame away from the LED panel; a plurality of moving grooves are formed on the fixed frame; each sliding cylinder is located inside the corresponding moving groove; two rotating shafts are fixedly connected to the sliding cylinder; the rotating shafts are rotatably connected to the fixed frame.

[0008] As an improvement to the above solution, it further includes a limiting rod; two limiting holes are respectively formed on the upper surface and the lower surface 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 a rubber rod; both vertical sections of the limiting rod are made of metal.

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

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

[0012] As an improvement to the above solution, 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, it further includes a connecting strip; a connecting strip for evenly transmitting the extrusion force is connected between every two adjacent sliding cylinders up and down; the connecting strip is rotatably connected to the rotating shaft of the corresponding sliding cylinder.

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

[0015] Beneficial effects: The present invention realizes that the faulty module protrudes from the adjacent modules by pressing, and the user can directly grasp the faulty module for disassembly without using tools such as suction cups, which is convenient and fast. At the same time, there is no need to press other normal modules, avoiding damage to the normal modules. The magnet is divided into two parts: a magnetic ring and magnetic blocks. When the user presses the LED panel to make the module extend for disassembly, the magnetic blocks are separated from the adsorption of the mounting bracket, thereby reducing the adsorption area of the overall magnet with the mounting bracket, and further reducing the stability of the module adsorbed on the mounting bracket, making it convenient for the user to remove the module from the mounting bracket. At the same time, the connection between the module and the mounting bracket is maintained through the magnetic ring to prevent the module from falling directly and pulling the connected wires, resulting in circuit damage; When disassembling the modules installed in the convex and concave situations, press the LED panel in areas, so that the module protrudes in areas, and cooperate with the limiting rod to limit the shapes of the LED panel and the fixing frame, to prevent the two sides of the arc-shaped LED panel and the fixing frame from deforming and contacting the adjacent modules, forming frictional resistance and affecting the outward extension of the LED panel and the fixing frame.

[0018] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0019] Embodiment 1 As Figures 1-13 shown, an outdoor high-brightness MiniLED backlight module includes an LED panel 1 and a fixing frame 2; the fixing frame 2 is fixedly connected to the back of the LED panel 1; a control circuit, a plurality of MiniLED lamp beads and a connecting plug are arranged on the back of the LED panel 1; It further includes a pressing and pushing flat component, a magnet 5, a sliding sleeve 6 and a sliding rod 7; six pressing and pushing flat components distributed in a matrix are connected to the fixing frame 2; each pressing and pushing flat component is connected to a magnet 5; the magnet 5 is composed 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 flat component; each pressing and pushing flat component is connected to a sliding rod 7; the sliding rod 7 passes through the corresponding sliding sleeve 6 and is slidably connected thereto; a limiting piece is fixedly connected to one end of the sliding rod 7 passing through the sliding sleeve 6.

[0020] The pressing and pushing component includes a sliding cylinder 3 and a sliding block 4; the sliding cylinder 3 is connected to the fixed frame 2; the sliding cylinder 3 is horizontally arranged, and the opening of the sliding cylinder 3 faces away from the LED panel 1; the sliding rod 7 is fixedly connected to the sliding cylinder 3; a locking rod 31 is rotatably connected in the sliding cylinder 3; a sliding block 4 is slidably connected in the sliding cylinder 3; a sliding sleeve 6 is slidably connected to the sliding block 4; an elastic member 32 is fixedly connected between the sliding cylinder 3 and the sliding block 4; the elastic member 32 is a spring; a locking groove 41 is formed in the sliding block 4; the locking groove 41 is composed of two V-shaped parts 42 and two horizontal parts 44; a top block 43 is arranged between the sliding block 4 and the left V-shaped part 42; the locking rod 31 moves in the locking groove 41; a magnetic ring 51 is fixedly connected to the side of the sliding block 4 away from the sliding cylinder 3; a receiving groove 45 is formed in the side of the sliding block 4 away from the sliding cylinder 3; the receiving groove 45 has the same shape as the magnetic block 52.

[0021] It also includes a rotating shaft 201; the LED panel 1 is a flexible circuit board; the fixed frame 2 is made of rubber, and a plurality of bending grooves are formed on the surface of the fixed frame 2 away from the LED panel 1; six moving grooves 21 are formed in the fixed frame 2; each sliding cylinder 3 is located in the corresponding moving groove 21; two symmetrically distributed rotating shafts 201 are fixedly connected to the sliding cylinder 3 along the vertical line; the rotating shaft 201 is rotatably connected to the fixed frame 2.

[0022] It also includes a limiting rod 202; two limiting holes 22 are formed on the upper surface and the lower surface of the fixed frame 2 respectively; two U-shaped limiting rods 202 are detachably connected to the fixed frame 2; the limiting rod 202 is adapted to the limiting hole 22.

[0023] The horizontal section of the limiting rod 202 is a rubber rod; both vertical sections of the limiting rod 202 are made of metal; the horizontal rubber rod can change the distance between the two metal vertical sections, facilitating the user to insert the vertical sections of the limiting rod 202 into the limiting holes 22.

[0024] The end of the vertical section of the limiting rod 202 is conical; it is convenient to insert into the limiting hole 22.

[0025] The cross-section of the locking rod 31 is circular; it reduces the frictional force when the locking rod 31 moves in the locking groove 41 and ensures smoothness.

[0026] The inner circumferential surface of the magnetic ring 51 and the outer circumferential surface of the magnetic block 52 are smooth surfaces; it reduces the frictional resistance between the magnetic ring 51 and the magnetic block 52.

[0027] When disassembling a single faulty module in the middle of multiple backlight modules, there are usually two methods. One is to adsorb the surface of the faulty module with a suction cup and remove the module from the bracket. The other is to squeeze the modules adjacent to the faulty module inward, causing the faulty module to be misaligned with the adjacent modules, and then snapping the faulty module off the bracket. The former requires the use of a suction cup tool, and for some faulty modules at certain heights, tools such as ladders are needed to reach them. When using the suction cup to adsorb and pull out the faulty module, a pulling force needs to be applied. At the moment of pulling out the faulty module, the user is prone to losing their balance and falling. The latter requires strong pressing on the normal modules, which is likely to damage the adjacent normal modules.

[0028] Therefore, the present invention provides an outdoor high-brightness MiniLED backlight module, aiming to solve the above problems.

[0029] Taking Figure 6 as the perspective reference, the side where the mounting frame 1111 label is located is the left side, and the side where the LED panel 1 label is located is the right side. In the initial state of the pressing and pushing component of the present invention, the slider 4 is retracted into the sliding 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 member 32 is in a compressed state; the magnetic ring 51 and the magnetic block 52 are flush. When installing the present invention, there are wires arranged between the mounting frames 1111. First, connect the wires to the connection plugs on the back of the LED panel 1. Then, the user installs the LED panel 1 on the mounting frame 1111 and fixes the present invention on the mounting frame 1111 through all the magnets 5. After that, in the same way, according to the required coverage area, install multiple of the present inventions, and they are seamlessly spliced as Figure 1 shown, thus completing the combined installation of multiple of the present inventions to form a large display panel.

[0030] When it is necessary to disassemble a single faulty module in the middle, the user gently presses the LED panel 1 of the faulty module in the direction of the mounting frame 1111 by contacting the front of the LED panel 1 of the faulty module with both hands. As Figure 6 shown, the LED panel 1 squeezes the fixing frame 2, and the fixing frame 2 squeezes the sliding cylinder 3 through the rotating shaft 201. The sliding cylinder 3 will squeeze the corresponding elastic member 32. At the same time, the sliding cylinder 3 drives the locking rod 31 to move leftward. The locking rod 31 contacts the top block 43 and is guided to move into the horizontal part 44. It should be noted that during the process of the sliding cylinder 3 driving the locking rod 31 to move, 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 sliding cylinder 3. Then, the user releases the pressing on the LED panel 1, the elastic member 32 expands, pushes the sliding cylinder 3, the sliding cylinder 3 pushes the LED panel 1 and the fixing frame 2 to move away from the mounting frame 1111. The sliding cylinder 3 will drive the locking rod 31 to move rightward in the horizontal part 44. 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, and then the locking rod 31 is restricted by the V-shaped part 42 on the right side, thereby causing the sliding cylinder 3 to stop moving. As Figure 7As shown, at this time, the slider 4 is still connected to the mounting bracket 1111 by the magnet 5, and the sliding cylinder 3 drives the LED panel 1 and the fixing frame 2 away from the mounting bracket 1111. Finally, as Figure 11 shown, the LED panel 1 and the fixing frame 2 of the faulty module to be disassembled protrude from the adjacent modules. At this time, the user can grab the protruding outer edge of the LED panel 1 and the fixing frame 2 with his hand, pull out the faulty module from the mounting bracket 1111, so that the magnet 5 and the mounting bracket 1111 are disengaged from adsorption. Then, the user pulls out the wire from the connection plug of the faulty module. After replacing the new module, install the new module on the mounting bracket 1111 according to the foregoing installation steps to complete the disassembly and replacement of the faulty module. In summary, by pressing, the faulty module protrudes from the adjacent modules, which is convenient for the user to grab the faulty module for disassembly without using tools such as suction cups, and at the same time, there is no need to press other normal modules to avoid damaging the normal modules.

[0031] Furthermore, since there are multiple magnets 5, when the user disassembles and pulls out the module, a relatively large force is still required. When the magnet 5 is disengaged from the mounting bracket 1111 instantaneously, the user has no time to retract the force and is prone to falling. At the same time, the wire connected to the LED panel 1 is pulled, causing the wire to break. And if while pressing the LED panel 1 to make the whole module extend, the magnet 5 is disengaged from the adsorption of the mounting bracket 1111 at the same time. At this time, if the user does not catch the module in time, the module will fall downward, pulling the connected wire and causing the circuit to be damaged.

[0032] Therefore, in the present invention, the magnet 5 is divided into two parts, a magnetic ring 51 and a magnetic block 52, in order to Figure 6 take the direction as a reference. When the user presses the LED panel 1 to make the module extend to the right, as Figure 7 shown, when the sliding cylinder 3 moves to the right and away from the slider 4, the sliding cylinder 3 will drive the sliding rod 7 to move to the right. The sliding rod 7 first slides to the right in the sliding sleeve 6 until the limiting piece of the sliding rod 7 contacts the right side wall of the sliding sleeve 6, which will drive the sliding sleeve 6 to move to the right. The sliding sleeve 6 drives the magnetic block 52 to move to the right. Then, the magnetic block 52 is disengaged from the adsorption of the mounting bracket 1111 and enters the receiving groove 45. Thus, only the magnetic ring 51 remains adsorbed on the mounting bracket 1111, reducing the overall adsorption area of the magnet 5 and the mounting bracket 1111, and further reducing the stability of the module adsorbed on the mounting bracket 1111, which is convenient for the user to remove the module from the mounting bracket 1111. At the same time, the connection between the module and the mounting bracket 1111 is maintained through the magnetic ring 51 to avoid the module falling directly and pulling the connected wire, resulting in circuit damage.

[0033] In order to adapt to the arc-shaped mounting surface, in the prior art, the LED panel 1 and the fixing frame 2 are made of flexible materials and can be bent and deformed. Since the initial shapes of the LED panel 1 and the fixing frame 2 are straight, when the present invention is mounted in a curved shape, when the sliding cylinder 3 drives the LED panel 1 and the fixing frame 2 to extend to the right by extrusion, the LED panel 1 and the fixing frame 2 tend to return to the straight shape due to the plasticity of the material itself. As a result, the LED panel 1 and the fixing frame 2 are slightly deformed forward and backward, contacting 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.

[0034] Thus, as Figure 13 shown, there are two installation cases for the curved surface, namely the outward convex on the left side and the inward concave on the right side. It should be noted that each pressing and pushing component of the present invention can work independently.

[0035] First, take the outward convex case as an example: The user first presses the most convex position in the middle of the front surface of the LED panel 1 to the left, so that the sliding cylinder 3 corresponding to the middle of the fixing frame 2 is pressed and squeezes the elastic member 32. After the locking rod 31 is forced to move and unlock by the sliding cylinder 3, the user releases the pressing force, and the sliding cylinder 3 moves to the right. The sliding cylinder 3 pushes the middle parts of the LED panel 1 and the fixing frame 2 to the right, thereby increasing the outward convexity of the middle parts 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 subjected to a pulling force towards the middle and are separated from the adjacent modules, without contacting the adjacent modules to generate frictional resistance. Then, the user presses the front and rear sides of the LED panel 1, so that the corresponding sliding cylinders 3 extend, pushing the front and rear sides of the LED panel 1 and the fixing frame 2 to protrude, so that the overall of the LED panel 1 and the fixing frame 2 protrudes from the other modules. Then, the user grabs the protruding positions of the LED panel 1 and the fixing frame 2 and removes them from the mounting rack 1111.

[0036] Take the inward concave case as an example: The user first presses the front and rear positions of the front surface of the LED panel 1. At this time, as Figure 13 shown on the right side, the magnets 5 on the front and rear sides of the fixing frame 2 are inclined towards the middle of the fixing frame 2, and the sliding cylinders 3 are on the same axis as the magnets 5. When the sliding cylinders 3 on the front and rear sides extend, they squeeze the front and rear sides of the LED panel 1 and the fixing frame 2 towards the middle. As a result, the front and rear sides of the LED panel 1 and the fixing frame 2 are separated from the adjacent modules, and thus do not contact the adjacent modules to generate frictional resistance. Then, the user presses the middle part of the LED panel 1, so that the sliding cylinder 3 in the middle of the fixing frame 2 extends, pushing the middle part of the LED panel 1 and the fixing frame 2 to the right and flat. Then, the user grabs the LED panel 1 and the fixing frame 2 and removes them from the mounting rack 1111.

[0037] In addition, when the LED panel 1 and the fixing frame 2 are installed or disassembled in a curved arc shape, the LED panel 1 and the fixing frame 2 are deformed, which will drive the magnet 5 to shift, affecting the stability of the magnet 5 adsorbed on the mounting bracket 1111. Therefore, both the sliding cylinder 3 and the slider 4 of the same pressing and pushing component are located in the moving groove 21, and the sliding cylinder 3 is rotatably connected to the fixing frame 2 through the rotating shaft 201. Furthermore, when the fixing frame 2 is in a curved arc shape, the sliding 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, having good adaptability, maintaining stability, and the sliding cylinder 3 does not contact the wall surface of the moving groove 21, and the deformation of the fixing frame 2 will not cause the sliding cylinder 3 and related parts to deflect.

[0038] In the above two cases of outward convexity and inward concavity, the LED panel 1 and the fixing frame 2 protrude in a curved arc shape from the rest of the modules, but the protruding distance is short. The user can only hold the LED panel 1 and the fixing frame 2 with the fingertips of the fingers, which is not convenient for applying force. Therefore, when the sliding cylinder 3 extends to change the degree of outward convexity or inward 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. Then, the user applies force through the limiting rods 202, which is convenient for disassembling 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, fixing the current shape of the more protruding LED panel 1 and the fixing frame 2 to prevent it from recovering or deforming and hindering the contact with the side surfaces of adjacent modules.

[0039] Embodiment 2 Based on Embodiment 1, as Figures 4-7 and Figure 14 shown, it further includes a connecting strip 301; a connecting strip 301 is connected between every two adjacent sliding cylinders 3 up and down; the connecting strip 301 is rotatably connected to the rotating shaft 201 of the corresponding sliding cylinder 3. Furthermore, when the sliding cylinder 3 rotates relative to the fixing frame 2 through the rotating shaft 201, it does not drive the connecting strip 301 to rotate, avoiding the connecting strip 301 restricting the rotation of the sliding cylinder 3.

[0040] The connecting strip 301 is made of a low-plasticity metal material; in the case of having a slight deformation ability, it ensures that the pressure received can be evenly transmitted to the corresponding two sliding cylinders 3.

[0041] When the user presses the LED panel 1, forcing the pressing and pushing component to unlock, so that the sliding cylinder 3 drives the LED panel 1 and the fixing frame 2 to extend away from the mounting bracket 1111. Since the LED panel 1 is a flexible circuit board and the fixing frame 2 is made of rubber, both have flexible properties. And the pressing and pushing component is located on the back of the LED panel 1, and the user cannot accurately view the position of each pressing and pushing component. Therefore, when the user presses the LED panel 1, the flexible LED panel 1 and the fixing frame 2 produce slight deformation, resulting in uneven transmission of the pressing force, and the upper and lower corresponding sliding cylinders 3 cannot receive the same pressing force at the same time, resulting in some sliding cylinders 3 being unable to move. The LED panel 1 and the fixing frame 2 extend to the right unevenly, and some edges are not exposed. The user cannot fully grasp the unevenly extended LED panel 1 and the fixing frame 2, making it difficult to disassemble. And if the user presses again to make the unextended sliding cylinder 3 extend, it may also cause the already extended sliding cylinder 3 to retract again, still forming a situation where only one side of the LED panel 1 and the fixing frame 2 extends outwards.

[0042] Therefore, a connecting strip 301 is connected between two sliding cylinders 3 in each vertical row. When the user presses the LED panel 1, the main coverage area of the pressing force is concentrated on the surface of the LED panel 1 corresponding to the connecting strip 301. Thus, when the user squeezes the LED panel 1, most of the squeezing force will act on the connecting strip 301. And the connecting strip 301 is made of low-plasticity metal material, ensuring that the pressure received can be effectively and evenly transmitted to the two sliding cylinders 3 in the corresponding vertical row, so that the two sliding cylinders 3 both receive sufficient pressing force from the compression elastic member 32. Then 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 are unlocked and extended, avoiding the situation that some sliding cylinders 3 cannot be actuated by pressing, the LED panel 1 and the fixing frame 2 extend to the right unevenly, some edges are not exposed, and the user cannot fully grasp the unevenly extended LED panel 1 and the fixing frame 2, making it difficult to disassemble.

[0043] The above embodiments are only the preferred embodiments of the present invention and are not used to limit the scope of implementation of the present invention. Therefore, any equivalent changes made according to the content described in the claims of the present invention should be included within the scope of the claims of the present invention.
