Technical Field

[0001] The invention relates to the technical field of heat dissipation structures, in particular to a heat diffusion structure based on an aluminum shell and an LED backlight source having the structure. Background Art

[0002] LED lights also generate heat during operation, the amount of which depends on the overall luminous efficiency. Under the action of external electrical energy, the radiation recombination of electrons and holes produces electroluminescence, and the light radiated near the PN junction needs to pass through the semiconductor medium and packaging medium of the chip itself before reaching the outside world.

[0003] LED advertising is a new media advertising form, which is a perfect combination of new media technology and outdoor advertising. LED advertising is the use of light-emitting diodes to form advertising words or pictures. For example, we usually see electronic large-screen advertisements on the street or some bright advertising words and signs with colorful lights on the roadside.

[0004] In large LED light sources, fans are needed to extract air from the inside to create flowing wind inside to take away the heat. However, due to the low hardness of aluminum, when the air inlet is blocked by debris when air enters, the suction force formed by the fan will cause a certain degree of negative pressure to form inside. If the negative pressure reaches a certain level, it will cause micro-deformation of the shell, and the negative pressure formed will interfere with the components inside the LED light source, affecting the use of the LED light source.

Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0023] As introduced in the background technology, there are deficiencies in the prior art. In order to solve the above technical problems, the present application proposes a heat diffusion structure based on an aluminum shell and an LED backlight source having the structure.

[0025] When in use, by starting the air cooling component 7, the air inside the diffusion component 5 can be extracted and a negative pressure can be formed inside it, so that the outside air can enter it. Since the outer surface of the diffusion component 5 is rotatably arranged with the inside of the shell 1, and one end thereof extends to the inside of the shell 1, the diffusion component 5 can absorb the heat inside the shell 1, and then cooperate with the outside air to exchange the hot air inside the diffusion component 5, so that the hot air can be discharged through the air cooling component 7, thereby achieving the purpose of rapid heat dissipation. By starting the driving component 3, the transmission component 4 movably arranged at its output end is driven to reciprocate. When the transmission component 4 moves, it can drive the diffusion component 5 fixedly connected at one end thereof to move left and right. Since one side of the cleaning component 6 is fixedly connected to one side of the diffusion component 5, and one side of the cleaning component 6 is in contact with one side of the filter component 2, when the diffusion component 5 moves, it can drive the cleaning component 6 to clean one side of the filter component 2, thereby preventing impurities from clogging the filter component 2.

[0026] The present invention starts the driving component 3 to drive the transmission component 4 movably arranged at its output end to perform reciprocating motion. When the transmission component 4 moves, it can drive the diffusion component 5 fixedly connected at one end thereof to move left and right. Since one side of the cleaning component 6 is fixedly connected to one side of the diffusion component 5, and one side of the cleaning component 6 is in contact with one side of the filter component 2, when the diffusion component 5 moves, it can drive the cleaning component 6 to clean one side of the filter component 2. When the air cooling component 7 is started, the air inside the diffusion component 5 can be extracted and a negative pressure can be formed inside the diffusion component 5, so that the outside air can enter the interior of the diffusion component 5 through the filter component 2, thereby preventing the filter component 2 from being blocked and damaging the shell 1, thereby avoiding affecting the use effect of the heat diffusion structure based on the aluminum shell and the LED backlight source having the structure.

[0029] Furthermore, for the above-mentioned driving component 3, the driving component 3 includes a motor 301, one side of the motor 301 is fixedly installed on the inner wall of the shell 1, the output end of the motor 301 is fixedly connected to a turntable 302, one side of the turntable 302 is fixedly connected to a movable rod 303, and the outer surface of the movable rod 303 is movably arranged inside the transmission component 4.

[0030] By starting the motor 301, the turntable 302 fixedly connected to its output end is driven to rotate. When the turntable 302 rotates, it can drive the movable rod 303 fixedly connected to one side thereof to perform circular motion. Since the outer surface of the movable rod 303 is movably arranged with the interior of the transmission component 4, when the movable rod 303 rotates in a circle, it can drive the transmission component 4 to move back and forth, so as to provide stable power for the transmission component 4.

[0031] Furthermore, for the above-mentioned transmission component 4, the transmission component 4 includes a fixed seat 401, one side of the fixed seat 401 is fixedly installed with the inner wall of the shell 1, and two groups of first movable frames 402 are slidably arranged inside the fixed seat 401, and both ends of the two groups of first movable frames 402 are fixedly connected with first wedge blocks 403, one side of one group of the first movable frames 402 is fixedly connected with a connecting frame 404, and the interior of the connecting frame 404 is movably arranged with the outer surface of the movable rod 303.

[0032] When the movable rod 303 performs circular motion with the rotation of the turntable 302, it can drive the connecting frame 404 movably arranged on its outer surface to move back and forth. When the connecting frame 404 moves, it can drive the first movable frame 402 fixedly connected to one side thereof to move. When the first movable frame 402 moves, it can drive the first wedge block 403 fixedly connected at both ends thereof to move. Since the outer surface of the first movable frame 402 is slidingly arranged with the inside of the fixed seat 401, when the first movable frame 402 moves, it can slide along the direction of the fixed seat 401, thereby improving the stability of the first movable frame 402 during movement.

[0033] Furthermore, for the transmission assembly 4, the transmission assembly 4 further includes two groups of second movable frames 405, the outer surfaces of the second movable frames 405 are slidably arranged inside the fixed seat 401, and both ends of the two groups of the second movable frames 405 are fixedly connected with second wedge blocks 406, and one side of the second wedge block 406 is in contact with one side of the first wedge block 403; The first movable frame 402 and the second movable frame 405 are both movably connected with a connecting rod 407 , and one end of the connecting rod 407 is fixedly connected to one side of the diffusion component 5 .

[0034] When the first wedge block 403 moves with the movement of the first movable frame 402, it can drive the second wedge block 406 that is fitted on one side thereof to move. When the second wedge block 406 moves, it can drive the second movable frame 405 that is fixedly connected on one side thereof to move. Since the first movable frame 402 and the second movable frame 405 are each provided with two groups, and two groups of first wedge blocks 403 and two groups of second wedge blocks 406 are provided at both ends, the two groups of first wedge blocks 403 and the two groups of second wedge blocks 406 are fitted on each other, so that they can move with each other. They push each other and make the two groups of first movable frames 402 and the two groups of second movable frames 405 move synchronously. When they move synchronously, they can drive the connecting rod 407 that is movably arranged inside to move. Since one end of the connecting rod 407 is fixedly connected to one side of the diffusion component 5, and the outer surface of the diffusion component 5 is rotatably arranged inside the shell 1, when the connecting rod 407 drives the diffusion component 5 to move, it can drive the diffusion component 5 to move in a circular motion, thereby increasing the heat contact area between it and the inside of the shell 1 and improving the heat absorption efficiency of the diffusion component 5.

[0035] Furthermore, for the above-mentioned diffusion component 5, the diffusion component 5 includes a support shaft 501, the interior of the support shaft 501 is fixedly installed with the interior of the shell 1, the interior of the support shaft 501 is provided with a through hole 502, and the outer surface of the support shaft 501 is rotatably provided with a heat dissipation shell 503, and one side of the heat dissipation shell 503 is fixedly connected to one end of the connecting rod 407.

[0036] When the connecting rod 407 moves with the movement of the first movable frame 402 and the second movable frame 405, it can drive the heat dissipation shell 503 fixedly connected at one end thereof to move. Since the interior of the heat dissipation shell 503 and the outer surface of the support shaft 501 are rotatably arranged, and the outer surface of the support shaft 501 is fixedly installed with the interior of the shell 1, when the heat dissipation shell 503 moves, it can make a circular reciprocating motion with the support shaft 501 as the center, so that it can quickly diffuse the heat inside the shell 1.

[0037] Furthermore, for the above-mentioned cleaning component 6, the cleaning component 6 includes a support seat 601, one side of the support seat 601 is fixedly connected to one side of the heat dissipation shell 503, one side of the support seat 601 is fixedly connected to a sliding rod 602, the outer surface of the sliding rod 602 is slidably provided with a sleeve 603, one side of the sleeve 603 is fixedly connected to a spring 604, one end of the sleeve 603 is fixedly installed with a cleaning brush 605, and one side of the cleaning brush 605 is in contact with one side of the filter 202.

[0038] When the heat dissipation shell 503 performs a circular motion with the movement of the connecting rod 407, it can drive the support seat 601 fixedly connected to one side thereof to move.

When the sleeve 603 moves, it can drive the cleaning brush 605 fixedly installed at one end thereof to move. When the cleaning brush 605 moves, it can clean the filter screen 202 fitted on one side thereof. Since the heat dissipation shell 503 performs a circular motion, during its circular motion, it can cooperate with the sleeve 603 to drive the cleaning brush 605 to perform a circular motion, and then cooperate with the spring 604 to push the sleeve 603 to move, so that the side on which it drives the cleaning brush 605 is always fitted with one side of the filter screen 202, thereby ensuring its cleaning efficiency.

[0039] Furthermore, for the above-mentioned cleaning component 6, the cleaning component 6 also includes two groups of air inlet holes 606 and two groups of offset holes 607.

The interiors of the two groups of air inlet holes 606 are connected with the interiors of the two groups of offset holes 607.

[0040] When the sleeve 603 moves with the circular motion of the heat dissipation shell 503, it can cooperate with the spring 604 and the filter 202 to enable the sleeve 603 to slide back and forth on the outer surface of the heat dissipation shell 503 during the movement, thereby driving the two groups of air inlet holes 606 opened inside it to be alternately connected with the offset holes 607 opened on the outer surface of the heat dissipation shell 503, so as to facilitate the outside air to enter the interior of the heat dissipation shell 503 through the air inlet holes 606 and the offset holes 607, so as to achieve the purpose of heat dissipation inside the heat dissipation shell 503.

[0042] By starting the fan 701, it cooperates with the air inlet pipe 702 to exhaust air, so that negative pressure is formed inside. Since the connecting pipe 703 is fixedly connected to one side of the air inlet pipe 702, and its interior is connected with the interior of the support shaft 501, the air inside the support shaft 501 can enter the interior of the air inlet pipe 702 through the connecting pipe 703. Since the through hole 502 is opened inside the support shaft 501, and its interior is connected with the interior of the heat dissipation shell 503, the air inside the heat dissipation shell 503 can enter the interior of the support shaft 501 through the through hole 502, and cooperate with the fan 701 to be discharged from the interior of the shell 1, so that the heat inside the shell 1 can be quickly dissipated.

[0044] By fixing the LED light source 10 to one side of the mounting frame 9 and fixing one side of the mounting plate 8 to one side of the housing 1, the LED light source 10 can be fixed to one side of the housing 1 so that the heat generated can be dissipated in conjunction with the housing 1, which is more convenient.

[0045] Working principle: When in use, the LED light source 10 is fixedly installed on one side of the mounting frame 9, and one side of the mounting plate 8 is fixedly installed on one side of the shell 1, so that the LED light source 10 can be fixedly installed on one side of the shell 1. During long-term operation, the LED light source 10 is prone to generate heat and accumulate inside the shell 1. The turntable 302 fixedly connected to its output end is driven to rotate by starting the motor 301. When the turntable 302 rotates, it can drive the movable rod 303 fixedly connected to one side thereof to perform circular motion. Since the outer surface of the movable rod 303 is movably arranged with the inside of the transmission component 4, when the movable rod 303 rotates in a circle, it can drive the connecting frame 404 movably arranged on its outer surface to move. When the connecting frame 404 moves, it can drive the first movable frame 402 fixedly connected to one side thereof to move. When the first movable frame 402 moves, it can drive the first wedge blocks 403 fixedly connected to both ends thereof to move. Since the outer surface of the first movable frame 402 is slidably arranged with the inner part of the fixed seat 401, when the first movable frame 402 moves, it can slide along the direction of the fixed seat 401.

When they move synchronously, they can drive the connecting rod 407 that is movably arranged inside to move. When the connecting rod 407 moves, it can drive the heat dissipation shell 503 that is fixedly connected at one end thereof to move. Since the interior of the heat dissipation shell 503 is rotatably arranged with the outer surface of the support shaft 501, and the outer surface of the support shaft 501 is fixedly arranged with the interior of the shell 1 The heat dissipation shell 503 is fixedly installed, and when the heat dissipation shell 503 moves, it can make a circular reciprocating motion with the support shaft 501 as the center, so that it can quickly diffuse the heat inside the shell 1.

When the sleeve 603 moves, it can drive the cleaning brush 605 fixedly installed at one end to move. When the cleaning brush 605 moves, it can clean the filter screen 202 that is fitted on one side of it. Then, the fan 701 is started to cooperate with the air inlet pipe 702 to exhaust air, so that negative pressure is formed inside it. Since one side of the air inlet pipe 702 is fixedly connected with the connecting pipe 703, and its interior is connected with the interior of the support shaft 501,The air inside the support shaft 501 can enter the air inlet pipe 702 through the connecting pipe 703. Since the through hole 502 is opened inside the support shaft 501 and the inside is connected with the inside of the heat dissipation shell 503, the air inside the heat dissipation shell 503 can enter the inside of the support shaft 501 through the through hole 502 and be discharged from the inside of the housing 1 with the help of the fan 701, so that the heat inside the housing 1 can be quickly dissipated.

[0046] Through the above technical scheme, 1. By starting the driving component 3, the transmission component 4 movably arranged at its output end is driven to reciprocate. When the transmission component 4 moves, it can drive the diffusion component 5 fixedly connected at one end thereof to move left and right. Since one side of the cleaning component 6 is fixedly connected to one side of the diffusion component 5, and one side of the cleaning component 6 is in contact with one side of the filter component 2, when the diffusion component 5 moves, it can drive the cleaning component 6 to clean one side of the filter component 2. When the air cooling component 7 is started, the air inside the diffusion component 5 can be extracted and a negative pressure can be formed inside the diffusion component 5, so that the outside air can enter the interior of the diffusion component 5 through the filter component 2, so that the filter component 2 can be prevented from being blocked and damaging the shell 1, thereby avoiding affecting the use effect of the heat diffusion structure based on the aluminum shell and the LED backlight source having the structure. 2.

Since the heat dissipation shell 503 performs circular motion, during its circular motion, it can cooperate with the sleeve 603 to drive the cleaning brush 605 to perform circular motion, and then cooperate with the spring 604 to push the sleeve 603 to move, so that the side of the cleaning brush 605 driven by it is always fitted with one side of the filter 202, thereby ensuring its cleaning efficiency. 3. Start the fan 701 and make it cooperate with the air inlet pipe 702 to exhaust air, so that negative pressure is formed inside. Since the connecting pipe 703 is fixedly connected to one side of the air inlet pipe 702, and its interior is connected with the interior of the support shaft 501, the air inside the support shaft 501 can enter the interior of the air inlet pipe 702 through the connecting pipe 703. Since the through hole 502 is opened inside the support shaft 501, and its interior is connected with the interior of the heat dissipation shell 503, the air inside the heat dissipation shell 503 can enter the interior of the support shaft 501 through the through hole 502, and cooperate with the fan 701 to be discharged from the interior of the shell 1, so that the heat inside the shell 1 can be quickly dissipated.

[0047] While the embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that many changes, modifications, substitutions and variations can be made to the embodiments without departing from the principles and spirit of the invention.
