Description

Technical Field

[0001] The invention relates to the technical field of LED modules, and in particular to a fastener-free and quickly assembled and disassembled LED module and a disassembly device thereof. Background Art

[0002] LED display is a flat panel display, which consists of small LED module panels and chassis walls. It is used to display various information such as text, images, and videos. The connection between LED modules and chassis walls is currently connected by fasteners such as screws in the industry. The LED modules are assembled into the mounting holes of the chassis walls. Due to the different sizes of each LED module, the number of fasteners is also different, ranging from 6 to more than 10. This causes the LED module installation process to require a large number of people to assemble, and the cost is also high. In addition, due to limitations such as the box structure, such as the limited working space of the back reinforcement ribs and the corners of the box, installation and disassembly are difficult. Secondly, the large number of fasteners will also lead to the hidden danger of missing locking, which is difficult to check and avoid. In addition, due to the large adjacent span between fasteners and the single-point locking force. The closer to the fastener area, the greater the force, the greater the compression of the sealing ring here, while the middle area between the two adjacent fasteners is the least stressed, and the compression of the sealing ring is also the smallest, resulting in uneven pressure and a wavy phenomenon of the sealing ring. This phenomenon will lead to hidden dangers in protection and deformation of the module, and permanently generate destructive stress. Over time, it will lead to failure of protection, permanent deformation of the shell, deformation of the PCBA, and serious accidents such as desoldering and cold soldering caused by deformation stress of electronic components on the PCBA.

[0003] For example, the LED module installation device disclosed in patent number CN200710000540.X includes an LED substrate, a mounting shell that is combined with the back of the LED substrate and has a mounting hole formed at the edge, and a fixing part arranged on the mounting hole of the mounting shell. The fixing part includes a main body with a hole formed inside, a fastener assembled in the hole and the mounting hole at the back of the mounting shell and used to fix the main body on the back of the mounting shell, and fins extending to both sides of the main body. By assembling the fixing part in the combination hole and then rotating the fins, the LED module can be fixed to the frame. The fastener that sets the fixing part in the mounting hole on the back of the mounting shell should be one of a cross bolt, a flat bolt or a hexagonal bolt. The LED module installation device assembles the fixing part in the combination hole through the fastener, and then fixes the LED module to the frame through the fixing part, which results in that each module needs multiple fasteners for connection, requires a large number of people to assemble, and is troublesome to install and disassemble. Summary of the invention

[0004] In view of this, the present invention provides a fastener-free and quickly assembled and disassembled LED module and a disassembly device thereof to solve the above technical problems.

[0005] The fastener-free and quick-loading LED module is arranged on the chassis wall, and the chassis wall is provided with a plurality of mounting holes.

[0006] Furthermore, the body is in a rectangular structure and is hollow inside, so that the body is in a rectangular frame. The bottom shell also includes a plurality of support parts arranged on the body. The support parts are connected to the hollow inside of the body.

[0007] Furthermore, the fastener-free and quick-install LED module further comprises a sealing ring arranged on the bottom shell, a plurality of LED components arranged on the bottom shell, and a plurality of masks covering the LED components. The sealing ring is arranged in the mounting groove and fits against the chassis wall.

[0008] The disassembly device includes a lower cover assembly, a slider assembly slidably disposed on the lower cover assembly, and a rotating assembly rotatably disposed on the lower cover assembly. The lower cover assembly includes a bottom plate, four first limit blocks disposed on four corners of the bottom plate, and two second limit blocks disposed on the bottom plate. The second limit block is located between the two first limit blocks. The slider assembly includes two first sliders slidably disposed on the bottom plate, two second sliders slidably disposed on the bottom plate, four second guide wheels respectively disposed on the first and second sliders, and a plurality of disassembly holes respectively disposed on the first and second sliders. The first and second sliders are staggered and spaced from each other. The two first sliders and the two second sliders are symmetrically disposed with a symmetry plane respectively, and the symmetry planes of the two first sliders are perpendicular to the symmetry planes of the two second sliders. Each of the first and second sliders is provided with a row of the disassembly holes, and the positions of the disassembly holes correspond to the hook parts. The hook parts are inserted into the disassembly holes and the hook parts are in contact with the side walls of the disassembly holes. The rotating assembly includes a rotating disk rotatably disposed on the first and second sliders, and four second slide grooves on the rotating disk. The second chute is arc-shaped and its opening direction faces the center of the turntable. The second chute includes a first end point close to the center of the turntable and a second end point away from the center of the turntable. The four second guide wheels are respectively located in the four second chute and slide in the second chute as the turntable rotates.

[0009] Furthermore, the disassembly device also includes an upper cover arranged on the lower cover assembly, a through hole is opened at the center of the upper cover, and the turntable is located in the through hole.

[0010] Furthermore, the lower cover assembly also includes a connecting hole arranged at the center of the bottom plate, and a plurality of first guide wheels rotatably arranged on the bottom plate, and the first guide wheels are located around the first limiting block.

[0011] Furthermore, the rotating assembly further comprises a fixing member disposed on the rotating disk and a handle disposed on the rotating disk. The fixing member passes through the rotating disk and is threadedly connected to the connecting hole.

[0012] Furthermore, a right-angle groove is provided on both sides of the first and second sliding blocks, and the first limit block is located in the two right-angle grooves on the opposite sides of the first and second sliding blocks.

[0013] Furthermore, a first sliding groove is provided at the center of the second sliding block, and the second limiting block is located in the first sliding groove.

[0014] Further, the first and second sliders slide on the bottom plate, and the sliding direction approaches or moves away from the center of the bottom plate.

The side wall of the first limit block perpendicular to the sliding direction of the first and second sliders is spaced apart from the first and second sliders. The side wall of the second limit block perpendicular to the sliding direction of the second slider is spaced apart from the second slider.

[0015] Compared with the prior art, the fastener-free and quickly assembled and unassembled LED module provided by the present invention is connected to the chassis wall through the fixing part, specifically. The fixing part includes a hook part, a hook, and a limiting rib. The end of the hook part is extended so that the length of the hook part is greater than the length of the limiting rib, thereby facilitating the disassembly device or manual disassembly. One end of the hook is in contact with the chassis wall, and the other end is inclined to have a guide surface, so that when the fixing part is inserted into the mounting hole, the guide surface first contacts the side wall of the mounting hole, thereby squeezing the hook part, so that the hook part is inclined in the direction of the limiting rib, and then the hook part can pass through the mounting hole. After passing through the mounting hole, the hook part is restored so that the hook is in contact with the chassis wall, and the limiting member is protruding and in contact with the chassis wall, so that it can cooperate with the hook to clamp the chassis wall. No fasteners are required, which greatly reduces costs. Compared with the traditional connection through screws, the width of the fixing part is larger than the screws, and the force is changed from a single point to a surface force. The force range is relatively uniform, which can minimize the wavy phenomenon of the sealing ring. At the same time, the protruding setting of the limiter can also limit the compression of the sealing ring to prevent the sealing ring from being over-compressed and losing the sealing effect. The disassembly device slides the first and second sliders toward the center direction of the bottom plate, so that the disassembly hole drives the hook part to bend obliquely toward the direction of the limiting rib, so that the hook is no longer in contact with the chassis wall and can pass through the installation hole, and then the bottom shell is taken out. All the hook parts can be disassembled at the same time, which greatly improves the disassembly efficiency. BRIEF DESCRIPTION OF THE DRAWINGS

[0026] The specific embodiments of the present invention are further described in detail below. It should be understood that the description of the embodiments of the present invention herein is not intended to limit the protection scope of the present invention.

[0027] like Figures 1 to 5 As shown, it is a schematic diagram of the structure of the fastener-free and quick-assembled LED module provided by the present invention. The fastener-free and quick-assembled LED module includes a bottom shell 10, a sealing ring 20 arranged on the bottom shell 10, a plurality of LED components 30 arranged on the bottom shell 10, and a plurality of masks 40 covering the LED components 30. It can be imagined that the fastener-free and quick-assembled LED module also includes some other functional modules, such as a sealant for sealing the LED components 30, etc., which are well known to those skilled in the art and will not be described in detail here.

[0028] First of all, it should be explained that the fastener-free and quick-install LED module is arranged on the chassis wall 1. The chassis wall 1 is provided with a plurality of mounting holes 2, and the mounting holes 2 are rectangular in shape so that the mounting holes 2 can cooperate with the fastener-free and quick-install LED module. The chassis wall 1 and the mounting holes 2 are prior art and will not be described in detail here.

[0029] The bottom shell 10 includes a body 11, a plurality of supporting parts 12 disposed on the body 11, a plurality of fixing parts 13 disposed on the body 11, a mounting groove 14 disposed on the body 11, and a stopper 15 disposed on the body 11. The bottom shell 10 is integrally formed and can be made by injection molding, and the material of the bottom shell 10 is plastic.

[0030] The main body 11 is in a rectangular structure and is hollow inside, so that the main body 11 is in a rectangular frame. The main body 11 is used to carry the above-mentioned functional modules.

[0031] The support portion 12 is connected to the hollow interior of the body 11 . The support portion 12 can support a plurality of the LED components 30 and improve the structural strength of the body 11 .

[0032] A plurality of the fixing portions 13 are arranged on an end face of the body 11 facing the chassis wall 1, and are used to be inserted into the mounting hole 2. The plurality of the fixing portions 13 are arranged along the edge of the body 11 and each of the fixing portions 13 corresponds to the position of each of the mounting holes 2, and the plurality of the fixing portions 13 are arranged in a rectangular shape. Each of the adjacent fixing portions 13 is arranged at intervals, so that the fixing portions 13 are evenly distributed on the body 11, so that the force range after assembly is even. Each of the fixing portions 13 includes a hook portion 131 arranged on the body 11, a hook 132 arranged on the hook portion 131, and a limiting rib 133 arranged on the body 11.

[0033] The cross section of the hook portion 131 is rectangular, and because the bottom shell 10 is made of plastic material, the hook portion 131 can be slightly tilted and bent. The hook portion 131 is located between the limiting member 15 and the limiting rib 133, and the hook portion 131 is spaced apart from the limiting rib 133 and the limiting member 15, thereby providing the space required for the hook portion 131 to be tilted and bent. The end of the hook portion 131 is extended so that the length of the hook portion 131 is greater than the length of the limiting rib 133, thereby facilitating disassembly of the device or manual disassembly. During disassembly, the hook portion 131 can be tilted toward the direction of the limiting rib 133 by directly pressing the end of the hook portion 131. The hook 132 is arranged on one side of the hook portion 131 close to the limiting member 15, and is located in the middle of the hook portion 131. One end of the hook 132 is in contact with the chassis wall 1, and the other end is tiltedly provided with a guide surface 1321, so that when the fixing portion 13 is inserted into the mounting hole 2, Figure 5As shown, the guide surface 1321 first contacts the side wall of the mounting hole 2, thereby squeezing the hook portion 131, causing the hook portion 131 to tilt toward the direction of the limiting rib 133, and then allowing the hook portion 131 to pass through the mounting hole 2. After passing through the mounting hole 2, the hook portion 131 is restored, so that the hook 132 is attached to the chassis wall 1 and limits the movement of the body 11. The cross-section of the limiting rib 133 is a right-angled triangle structure, and includes an inclined surface 1331 and a right-angled surface 1332. The inclined surface 1331 abuts against the side wall of the mounting hole 2, thereby preventing the bottom shell 10 from falling, and cooperates with the hook portion 131 to limit the movement of the bottom shell 10 in the vertical direction. The right-angle surface 1332 is located between the inclined surface 1331 and the hook portion 131, and the plane where the right-angle surface 1332 is located is parallel to the plane where the hook portion 131 is located, so that the right-angle surface 1332 can resist the hook portion 131 when the hook portion 131 is tilted and bent, ensuring that the inclination of the hook portion 131 does not exceed the limit parameter, so as to prevent the hook portion 131 from breaking and failing due to excessive tilt.

[0034] The mounting groove 14 is in a semicircular groove structure and faces the chassis wall 1, and is used to set the sealing ring 20. The limiting member 15 is located between the mounting groove 14 and the hook portion 131. The limiting member 15 is protrudingly arranged and fits the chassis wall 1, so as to cooperate with the hook 132 to clamp the chassis wall 1 and limit the horizontal movement of the bottom shell 10. The inclined surface 1331 cooperates with the hook portion 131 to limit the vertical movement of the bottom shell 10, thereby fixing the bottom shell 10 on the chassis wall 1, without the need for fasteners, which greatly reduces costs. At the same time, the protruding arrangement of the limiting member 15 can also limit the compression amount of the sealing ring 20, preventing the sealing ring 20 from being over-compressed and losing the sealing effect.

[0035] The sealing ring 20 is arranged in the installation groove 14 and fits with the chassis wall 1 to play a sealing role. Since the body 11 is connected to the chassis wall 1 through the fixing portion 13, compared with the traditional connection through screws, the width of the fixing portion 13 is larger than the screw, and the force is changed from a single point to a surface force, and the force range is relatively uniform, which can minimize the wave-like phenomenon of the sealing ring 20.

[0036] The LED assembly 30 is disposed on the body 11 and the support portion 12 and is used to emit light. The mask 40 is disposed on the LED assembly 30 and is used to protect the LED assembly 30 and prevent dust and foreign matter from entering. The LED assembly 30 and the mask 40 are prior art and will not be described in detail herein.

[0037] The fastener-free and quick-install LED module is installed on the chassis wall 1 by applying pressure from the front, and the hook 132 is located on the back of the chassis wall 1, which makes it difficult to disassemble. Therefore, the present invention also provides a disassembly device for disassembling the fastener-free and quick-install LED module. Figures 6 to 10 As shown, it is a schematic diagram of the structure of the disassembly device for disassembling the fastener-free and quick-install LED module provided by the present invention. The disassembly device includes a lower cover assembly 100, a slider assembly 200 slidably disposed on the lower cover assembly 100, an upper cover 300 disposed on the lower cover assembly 100, and a rotating assembly 400 rotatably disposed on the lower cover assembly 100. It can be imagined that the disassembly device also includes some other functional modules, such as a connecting assembly, an installation assembly, etc., which are well known to those skilled in the art and will not be described in detail here.

[0038] The lower cover assembly 100 includes a base plate 110, a connecting hole 120 arranged at the center position of the base plate 110, four first limit blocks 130 arranged at the four corners of the base plate 110, two second limit blocks 140 arranged on the base plate 110, and a plurality of first guide wheels 150 rotatably arranged on the base plate 110.

[0039] The bottom plate 110 is used to carry the above-mentioned internal components. The connection hole 120 is internally threaded and is used to set the rotating component 400. The second limit block 140 is located between the two first limit blocks 130. The first and second limit blocks 130, 140 are used to limit the sliding direction of the slider assembly 200, so that the sliding direction of the slider assembly 200 can only be close to or away from the center of the bottom plate 110. The specific description will be described below in conjunction with the slider assembly 200. The first guide wheel 150 is located around the first limit block 130 and is used to rotate when the slider assembly 200 slides, playing the role of guiding and supporting the sliding of the slider assembly 200.

[0040] The slider assembly 200 includes two first sliders 210 slidably disposed on the base plate 110, two second sliders 220 slidably disposed on the base plate 110, four second guide wheels 230 respectively disposed on the first and second sliders 210, 220, and a plurality of disassembly holes 240 respectively disposed on the first and second sliders 210, 220.

[0041] The first and second sliders 210, 220 are roughly triangular structures. The first and second sliders 210, 220 are staggered and spaced apart from each other. The two first sliders 210 and the two second sliders 220 are symmetrically arranged with a symmetry plane, and the symmetry planes of the two first sliders 210 are perpendicular to the symmetry planes of the two second sliders 220. The first and second sliders 210, 220 slide on the bottom plate 110, and the sliding direction approaches or moves away from the center of the bottom plate 110. A right-angle groove 211 is provided on both sides of the first and second sliders 210, 220, so that the two right-angle grooves 211 on the opposite sides of the first and second sliders 210, 220 can be spliced ​​with each other. The first limit block 130 is located in the two right-angle grooves 211 on the opposite sides of the first and second sliders 210 and 220. The sidewalls of the first limit block 130 parallel to the sliding direction of the first and second sliders 210 and 220 are in contact with the first and second sliders 210 and 220, and are guided by the first guide wheel 150, thereby limiting the sliding direction of the first and second sliders 210 and 220. The sidewalls of the first limit block 130 perpendicular to the sliding direction of the first and second sliders 210 and 220 are spaced from the first and second sliders 210 and 220, thereby providing space for the first and second sliders 210 and 220 to slide and limiting the final positions of the first and second sliders 210 and 220. A first sliding groove 221 is provided at the center of the second slider 220, and the second limit block 140 is located in the first sliding groove 221. The side wall of the second limit block 140 perpendicular to the sliding direction of the second slider 220 is spaced apart from the second slider 220 , thereby providing a sliding space for the second slider 220 and limiting the final position of the second slider 220 .

[0042] Each of the first and second sliders 210, 220 is rotatably provided with a second guide wheel 230, the second guide wheel 230 is connected to the rotating component 400, and the second guide wheel 230 is driven to move by rotating the rotating component 400, and then the second guide wheel 230 drives the first and second sliders 210, 220 to slide, and the specific description will be explained below in conjunction with the rotating component 400.

[0043] Each of the first and second sliders 210 and 220 is provided with a row of disassembly holes 240, and the position and size of the disassembly holes 240 correspond to the hook portion 131, so that the hook portion 131 can be inserted into the disassembly hole 240 and the end of the hook portion 131 is in contact with the side wall of the disassembly hole 240. When disassembling the fastener-free and quick-install LED module, each of the hook portions 131 is first inserted into each of the disassembly holes 240, and then the first and second sliders 210 and 220 are slid toward the center of the bottom plate 110, thereby driving the hook portion 131 to bend obliquely toward the direction of the limiting rib 133, as shown in FIG. Fig.10 The hook 132 is no longer attached to the chassis wall 1 and can pass through the mounting hole 2, and then the bottom shell 10 is taken out, and all the hook parts 131 can be disassembled at the same time, which greatly improves the disassembly efficiency.

[0044] The upper cover 300 is disposed on the first and second limit blocks 130 and 140 and connected by inserting fasteners. The upper cover 300 is used to limit the vertical movement of the first and second sliders 210 and 220 and to set the rotating assembly 400. In order to set the rotating assembly 400, a through hole 310 is opened in the center of the upper cover 300.

[0045] The rotating assembly 400 includes a turntable 410 rotatably disposed on the first and second sliders 210 and 220 , a fixing member 420 disposed on the turntable 410 , four second slide slots 430 disposed on the turntable 410 , and a handle 440 disposed on the turntable 410 .

[0046] The rotating disk 410 is located in the through hole 310, and the fixing member 420 passes through the rotating disk 410 and is threadedly connected to the connecting hole 120, so as to prevent the rotating disk 410 from falling. The four second guide wheels 230 are respectively located in the four second slide grooves 430, and slide in the second slide grooves 430 as the rotating disk 410 rotates. The second slide groove 430 is arc-shaped and the opening direction faces the center of the rotating disk 410. The second slide groove 430 includes a first end point 431 close to the center of the rotating disk 410, and a second end point 432 away from the center of the rotating disk 410. When the second guide wheel 230 slides from the second end point 432 to the first end point 431, since the second guide wheel 230 is close to the center of the rotating disk 410, the first and second sliders 210 and 220 are driven to move toward the center of the bottom plate 110, so that the disassembly hole 240 can press the hook part 131, so that the hook part 131 is inclined and bent toward the direction of the limiting rib 133, and vice versa. The handle 440 can facilitate people to rotate the rotating disk 410.

[0047] Compared with the prior art, the fastener-free and quickly assembled and disassembled LED module provided by the present invention is connected to the chassis wall 1 through the fixing portion 13, specifically. The fixing portion 13 includes a hook portion 131, a hook 132, and a limiting rib 133. The end of the hook portion 131 is extended so that the length of the hook portion 131 is greater than the length of the limiting rib 133, thereby facilitating the disassembly device or manual disassembly. One end of the hook 132 is in contact with the chassis wall 1, and the other end is obliquely provided with a guide surface 1321, so that when the fixing portion 13 is inserted into the mounting hole 2, the guide surface 1321 first contacts the side wall of the mounting hole 2, thereby squeezing the hook portion 131, so that the hook portion 131 is inclined in the direction of the limiting rib 133, and then the hook portion 131 can pass through the mounting hole 2. After passing through the mounting hole 2, the hook portion 131 is restored, so that the hook 132 is fitted with the chassis wall 1, and the stopper 15 is protrudingly arranged and fits with the chassis wall 1, so that it can cooperate with the hook 132 to clamp the chassis wall 1. No fasteners are required, which greatly reduces the cost. Compared with the traditional connection by screws, the width of the fixing portion 13 is larger than that of the screws, and the force is changed from a single point to a surface force, and the force range is relatively uniform, which can minimize the wave-like phenomenon of the sealing ring 20. At the same time, the protruding setting of the stopper 15 can also limit the compression of the sealing ring 20, preventing the sealing ring 20 from being over-compressed and losing the sealing effect. The disassembly device slides the first and second sliders 210 and 220 toward the center direction of the bottom plate 110, so that the disassembly hole 240 drives the hook part 131 to bend obliquely toward the direction of the limiting rib 133, so that the hook 132 is no longer in contact with the chassis wall 1 and can pass through the installation hole 2, and then the bottom shell 10 is taken out, and all the hook parts 131 can be disassembled at the same time, thereby greatly improving the disassembly efficiency.

[0048] The above are only preferred embodiments of the present invention and are not intended to limit the protection scope of the present invention. Any modification, equivalent substitution or improvement within the spirit of the present invention is included in the scope of the claims of the present invention.
