Description

Technical Field

[0001] This utility model relates to the field of circuit board technology, and in particular to a heat dissipation structure for a Ferris wheel-shaped multi-color light circuit board. Background Technology

[0002] The Ferris wheel-shaped multi-color light circuit board heat dissipation structure uses a high thermal conductivity aluminum substrate to support multi-color LED beads. Heat is conducted to the central aluminum alloy shaft with radial fins through thermal conductive materials. The metal spokes connecting the center and the edge assist in heat transfer. The rotation of the Ferris wheel drives airflow, which enhances the convective heat dissipation between the central shaft and the outside world, forming an efficient heat dissipation path.

[0003] The heat generated by the multi-colored LED beads is first quickly absorbed by the high thermal conductivity aluminum substrate, and then conducted to the central aluminum alloy shaft through the thermal conductive material. At the same time, the heat from the edge LED beads is transferred to the central shaft with the assistance of the metal spokes. Utilizing the airflow driven by the rotation of the Ferris wheel, the central shaft fins and the flowing air are efficiently convected, dissipating the accumulated heat into the environment and forming a continuous heat dissipation cycle from the LED beads to the air.

[0004] In existing technologies, the heat dissipation of some Ferris wheel-shaped multi-color light circuit boards usually involves the LED beads transferring heat to the aluminum substrate, then to the central axis, and finally the heat being carried away by the air. If heat dissipation is difficult along the heat transfer path, the heat can only accumulate in one direction. The heat generated by the LED beads cannot be dissipated on the surface of the aluminum substrate through natural convection, which will cause the substrate temperature to rise sharply, directly aggravating the light decay and color accuracy shift of the LED beads. Therefore, a Ferris wheel-shaped multi-color light circuit board heat dissipation structure is proposed to solve the above problems. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a heat dissipation structure for a Ferris wheel-shaped multi-colored light circuit board, aiming to improve the problem of heat dissipation difficulties in the heat transfer path of the Ferris wheel-shaped multi-colored light circuit board heat dissipation structure.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A heat dissipation structure for a Ferris wheel-shaped multi-colored light circuit board includes a circuit board body, multiple heat conduction mechanisms fixedly connected to the outside of the circuit board body, a central shaft rotatably connected inside the circuit board body, a protective mechanism fixedly connected to the outside of the circuit board body, and a base fixedly connected to the bottom of the central shaft.

[0008] The heat conduction mechanism includes a circuit board branch, a heat dissipation plate is fixedly connected to the top of the circuit board branch, a heat dissipation layer is fixedly connected to the top of the circuit board body, a heat conduction plate is fixedly connected to the outside of the heat dissipation plate, and a heat dissipation component is fixedly connected to the outside of the circuit board branch.

[0009] As a further description of the above technical solution:

[0010] The heat dissipation assembly includes multiple connecting blocks, with connecting rods fixedly connected inside the multiple connecting blocks, and heat dissipation plates fixedly connected to adjacent sides of the multiple connecting blocks;

[0011] As a further description of the above technical solution:

[0012] The adjacent sides of the plurality of connecting blocks are fixedly connected to both sides of the circuit board branch, and the interior of the connecting rod is fixedly connected to the interior of the heat sink.

[0013] As a further description of the above technical solution:

[0014] The circuit board branch is fixedly connected to the outside of the circuit board body, and the heat spreader plate is fixedly connected to the outside of the circuit board branch.

[0015] As a further description of the above technical solution:

[0016] The bottom of the heat-conducting plate is fixedly connected to the top of the circuit board branch, and the other end of the circuit board branch is fixedly connected to a lamp ball;

[0017] As a further description of the above technical solution:

[0018] The protective mechanism includes a protective shell, with multiple outer shells fixedly connected to the outside of each protective shell. Multiple ventilation holes are provided inside each outer shell. A support pad is fixedly connected to the outside of the central shaft. An unlocking component is fixedly connected to the outside of the protective shell.

[0019] As a further description of the above technical solution:

[0020] The unlocking component includes multiple upper locking blocks, multiple lower locking blocks are fixedly connected to the outside of the protective shell, springs are fixedly connected inside the multiple lower locking blocks, a slider is fixedly connected to the other end of the spring, and a rotating rod is interactively connected inside the upper locking blocks;

[0021] As a further description of the above technical solution:

[0022] The rotating rod is externally fixedly connected to the inside of the lower locking block, and the slider is slidably connected to the inside of the rotating rod.

[0023] This utility model has the following beneficial effects:

[0024] 1. In this utility model, heat is transferred to the circuit board branches through the lamp ball. When the circuit board branches transfer heat to the circuit board branches, the heat-conducting plate at the top of the circuit board branches absorbs and dissipates some of the heat. When the circuit board branches transfer heat to the circuit board branches, the heat dissipation plate at the top of the circuit board branches can also remove some of the heat from the circuit board branches. At the same time, in conjunction with the ventilation holes opened in the outer shell, some heat is directly removed during the heat transfer process, so that the heat generated by the lamp ball can be dissipated during the transfer process, reducing the heat accumulation on the central shaft, thereby making the heat dissipation of the circuit board heat dissipation structure more efficient.

[0025] 2. In this utility model, by rotating the rotating rod, the rotating rod presses the slider, thereby causing the slider to press the spring. When the rotating rod rotates to a certain angle, lifting the rotating rod upwards can cause the rotating rod to slide out from inside the lower locking block, thereby opening the unlocking component, which facilitates the inspection and maintenance of the circuit board body. The protective shell and outer shell provide protection for the circuit board, preventing the circuit board body and circuit board branches from being collided. Attached Figure Description

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

[0034] Reference Figure 2 and Figure 3 This utility model provides an embodiment of a heat dissipation structure for a Ferris wheel-shaped multi-colored light circuit board, comprising a circuit board body 1, with multiple heat-conducting mechanisms 2 fixedly connected to the outside of the circuit board body 1. Through the layered heat dissipation design of the heat-conducting mechanisms 2, the heat is initially dispersed. A central shaft 3 is fixedly connected inside the circuit board body 1, transferring the accumulated heat from the circuit board body 1 to the central shaft 3. Then, through the high thermal conductivity of the metal of the central shaft 3, the heat is concentrated. A protective mechanism 4 is fixedly connected to the outside of the circuit board body 1, covering the connection between the circuit board body 1 and the heat-conducting mechanisms 2. Through the hollow design of the protective mechanism 4, it guides airflow while isolating external dust, achieving the dual effect of auxiliary heat dissipation and protection. A base 6 is fixedly connected to the bottom of the central shaft 3, transferring the remaining heat to the base 6 through the central shaft 3. Then, through the contact between the base 6 and the mounting surface, the heat is finally diffused into the environment.

[0035] The heat conduction mechanism 2 includes a circuit board branch 21, which carries the dispersed multi-colored LED beads. The branch layout reduces local heat accumulation and disperses the heat source. A heat dissipation plate 22 is fixedly connected to the top of the circuit board branch 21, which transfers the heat from the LED beads to the heat dissipation plate 22. A heat dissipation layer 23 is fixedly connected to the top of the circuit board body 1, which allows heat to penetrate to the heat dissipation layer 23. The high specific surface area structure of the heat dissipation layer 23 enhances the heat exchange with the air. Heat conduction plates 24 are fixedly connected to the outside of the heat dissipation plate 22, which transfers the homogenized heat to the heat conduction plate 24. The lateral conduction characteristics of the heat conduction plate 24 direct the heat to the circuit board body 1 and the central axis 3. A heat dissipation component 25 is fixedly connected to the outside of the circuit board branch 21, which transfers the remaining heat to the heat dissipation component 25. The multi-dimensional heat dissipation structure of the heat dissipation component 25 enhances heat dissipation.

[0036] The heat dissipation component 25 includes multiple connecting blocks 251, which are fixedly connected to the circuit board branch 21. The connecting blocks 251 provide support, thus fixing the heat dissipation component 25 and transferring heat. Connecting rods 252 are fixedly connected inside the multiple connecting blocks 251. Heat is transferred from the connecting blocks 251 to the connecting rods 252. The through-type design of the connecting rods 252 helps to even out the heat from the multiple connecting blocks 251. A heat sink 253 is fixedly connected to one side of the multiple connecting blocks 251. Heat is transferred from the connecting blocks 251 and the connecting rods 252 to the heat sink 253. The finned structure of the heat sink 253 accelerates the airflow through the gaps between the fins when the Ferris wheel rotates, thus enhancing the heat dissipation effect.

[0037] Reference Figure 4 and Figure 5 The protective mechanism 4 includes a protective shell 41, which wraps around the key parts of the circuit board body 1 and the heat conduction mechanism 2. The outer shell 42 then achieves the protective effect of isolating external collisions and dust corrosion. Multiple outer shells 42 are fixedly connected to the outside of the protective shell 41. The supporting force of the protective shell 41 drives the outer shells 42 to form outwardly extending protective branches. The outer shells 42 then wrap around the circuit board branches 21 and the heat dissipation components 25, achieving a targeted protective effect for the edge heat dissipation components.

[0038] Multiple ventilation holes 43 are provided inside the outer shell 42. The structural positioning of the outer shell 42 drives the ventilation holes 43 to form airflow channels. The grid distribution of the ventilation holes 43 allows airflow while blocking large particles of impurities, achieving a protective effect without hindering heat dissipation. A support pad 44 is fixedly connected to the outside of the central shaft 3. The axial fixation of the central shaft 3 causes the support pad 44 to fit against the bottom of the protective shell 41. The cushioning effect of the support pad 44 reduces the vibration between the protective shell 41 and the central shaft 3 when the Ferris wheel rotates. An unlocking component 45 is fixedly connected to the outside of the protective shell 41. The structural support of the protective shell 41 drives the unlocking component 45 to achieve opening and closing control, making it easy to disassemble the protective shell 41 for internal maintenance.

[0039] The unlocking component 45 includes multiple upper locking blocks 451, which are fixedly connected to the upper half of the protective shell 41. The upper locking blocks 451 cooperate with the lower locking blocks 452 through their protruding structure to achieve a preliminary locking and positioning effect. Multiple lower locking blocks 452 are fixedly connected to the outside of the protective shell 41. The lower locking blocks 452 are aligned with the upper locking blocks 451 through the support of the lower half of the protective shell 41. The groove structure of the lower locking blocks 452 accommodates the upper locking blocks 451 and locks them in place. Springs 453 are fixedly connected inside the multiple lower locking blocks 452. The cavity structure of the lower locking blocks 452 drives the springs 453 to maintain a compressed and stored state. The elastic potential energy of the springs 453 pushes the slider 454 to provide a locking force.

[0040] The other end of the spring 453 is fixedly connected to a slider 454. The spring 453 pushes the slider 454 into the slot of the rotating rod 455. Then, through the locking action of the slider 454, the upper locking block 451 and the lower locking block 452 are rigidly fixed. The upper locking block 451 is slidably connected to the rotating rod 455. The rotating rod 455 is rotated by external force, causing its end to press the slider 454. Then, through the leverage of the rotating rod 455, the spring force of the spring 453 is overcome, causing the slider 454 to retract, thereby releasing the upper locking block 451 and the lower locking block 452 from locking.

[0041] Reference Figure 2 , Figure 3 and Figure 5 Multiple connecting blocks 251 are fixedly connected to the two sides of the circuit board branch 21 on adjacent sides. The heat generated during operation is transferred to the connecting blocks 251 on both sides through the circuit board branch 21. Through the conduction of the connecting blocks 251, the heat is evenly distributed to the heat dissipation component 25. The connecting rod 252 is fixedly connected to the inside of the heat sink 253. The connecting blocks 251 drive the connecting rod 252 to receive heat synchronously. Then, through the fixed connection between the connecting rod 252 and the heat sink 253, the dispersed heat is concentrated and transferred to the heat sink 253.

[0042] The circuit board branch 21 is fixedly connected to the outside of the circuit board body 1. Heat is conducted to the circuit board branch 21 through the circuit board body 1. The branch layout expands the heat dissipation area and prevents heat from accumulating in the main body area. The heat dissipation plate 22 is fixedly connected to the outside of the circuit board branch 7. Heat is transferred to the circuit board branch 7 through the heat dissipation plate 22. The extension structure of the branch diffuses the heat to the LED distribution area and balances the local temperature.

[0043] The bottom of the heat-conducting plate 24 is fixedly connected to the top of the circuit board branch 7. The heat generated by the lamp beads during operation is transferred to the top heat-conducting plate 24 through the circuit board branch 7. Then, through the high thermal conductivity of the heat-conducting plate 24, the heat from the branch is quickly transferred to the heat spreader 22. The other end of the circuit board branch 7 is fixedly connected to the lamp ball 5. The heat generated by the lamp ball 5 when it emits light is transferred to the circuit board branch 7. Then, through the linkage between the branch, the heat-conducting plate 24, and the heat spreader 22, a direct heat dissipation path is constructed for the lamp ball 5, and the lamp ball 5 is prevented from overheating.

[0044] The rotating rod 455 is externally fixedly connected to the inside of the lower locking block 452. The structure of the lower locking block 452 positions the rotating rod 455 to maintain a stable rotation trajectory. The rotation of the rotating rod 455 controls the opening and closing state of the unlocking component 45. The slider 454 is slidably connected to the inside of the rotating rod 455. The rotation of the rotating rod 455 drives the slider 454 to slide along its internal trajectory. The displacement of the slider 454 compresses or releases the spring 453, thereby achieving the locking or unlocking of the upper locking block 451 and the lower locking block 452, which facilitates the disassembly and maintenance of the protective shell 41.

[0045] Working principle: When the main body of the circuit board 1 is powered on, the main body of the circuit board 1 lights up the lamp ball 5 through the circuit board branch 21. When the lamp ball 5 is lit for a certain period of time, it generates heat. At this time, the heat generated by the lamp ball 5 is transferred to the main body of the circuit board through the circuit board branch 7 and the circuit board branch 21, and then transferred to the central shaft 3 by the main body of the circuit board 1. Finally, the heat generated by the lamp ball 5 is carried away by the air. When the lamp ball 5 generates heat, it transfers the heat to the circuit board branch 7. When the circuit board branch 7 transfers the heat to the circuit board branch 21, the heat conduction plate 24 at the top of the circuit board branch 7 absorbs and dissipates some of the heat. When the circuit board branch 7 transfers the heat to the circuit board branch 21, the heat dissipation plate 22 at the top of the circuit board branch 21 can also carry away some of the heat from the circuit board branch 21. At the same time, with the ventilation holes 43 opened in the outer shell 42, some of the heat is carried away directly during the heat transfer process, so that the heat generated by the lamp ball 5 can be dissipated during the transfer process, reducing the heat accumulation on the central shaft 3, thereby making the heat dissipation of the circuit board heat dissipation structure more efficient.

[0046] By rotating the lever 455, the lever 455 presses the slider 454, which in turn presses the spring 453. When the lever 455 rotates to a certain angle, lifting the lever 455 upwards allows the lever 455 to slide out from inside the lower locking block 452, thereby opening the unlocking assembly 45. This facilitates the maintenance of the circuit board body 1. The protective shell 41 and the outer shell 42 provide protection for the circuit board, preventing the circuit board body 1 and the circuit board branch 21 from being collided.

[0047] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
