Technical Field
[0001] This utility model relates to the field of LED display technology, and more specifically, to a control box assembly, an LED housing, and an LED display device. Background Technology
[0002] LED display devices are typically assembled from multiple LED cabinets, and the control box is the core component of the LED cabinet. The control box usually contains multiple electrical components, including a control module for control and a power supply module for providing power.
[0003] In this field, control boxes commonly come in two types: one is composed of a die-cast aluminum shell and a die-cast aluminum base plate, while the other, simpler, is directly formed by stamping sheet metal. Control boxes in this technology primarily rely on the metal shell to transfer the heat generated by the electrical components to the LED enclosure frame, thus achieving heat dissipation. However, electrical components generate a significant amount of heat during operation, and higher temperatures directly impact their lifespan. Current heat dissipation methods are not conducive to effectively cooling these components. Utility Model Content
[0004] The main objective of this invention is to provide a control box assembly, an LED enclosure, and an LED display device to solve the problem of poor heat dissipation in control boxes in related technologies.
[0005] To achieve the above objectives, according to one aspect of the present invention, a control box assembly is provided, comprising: a housing having a mounting cavity and an opening communicating with the mounting cavity, the housing having a first through hole; an electrical component disposed within the mounting cavity; and a cover connected to the housing and covering the opening, the outer surface of the cover having a plurality of raised strips, adjacent raised strips being spaced apart to form a drainage channel, and the cover also having a second through hole located within the drainage channel.
[0006] Furthermore, there are multiple second through holes, which are arranged at intervals along the extension direction of the drainage channel.

[0008] Furthermore, the control box assembly has a cuboid structure, and the housing includes a bottom plate, side plates, and end plates. The bottom plate extends along the length of the cuboid structure, and the side plates are connected to both sides of the bottom plate. The bottom plate, side plates, and cover form an end opening that communicates with the mounting cavity, and the end plates are detachably installed on the end opening.
[0009] Furthermore, there are multiple first through holes, and the multiple first through holes are disposed on the end plate; and / or, a first mounting seat is disposed on the cover, and a second mounting seat is disposed between the bottom plate and the side plate. The control box assembly also includes a first fastener and a second fastener, the first fastener passing through the end plate and the first mounting seat, and the second fastener passing through the end plate and the second mounting seat.
[0010] Furthermore, the control box assembly also includes a first circuit board and a second circuit board disposed within the mounting cavity. The first circuit board is connected to the inner side of the cover, and the second circuit board is connected to the inner side of the base plate. The electrical components include a control module and a power module. The control module is disposed on the first circuit board, and the power module is disposed on the second circuit board. And / or, a connecting lug is provided on the side of the end plate extending along the thickness direction of the cuboid structure.
[0011] Furthermore, the cover is made of plastic; and / or the shell is made of metal.
[0012] According to another aspect of the present invention, an LED enclosure is provided, including a frame and a control box assembly connected to the frame, wherein the control box assembly is the control box assembly described above.
[0013] Furthermore, the LED enclosure also includes LED modules disposed on the front side of the frame, with the LED modules spaced apart from the control box assembly, and the side panels of the control box assembly fitting into the frame.

[0015] By applying the technical solution of this utility model, electrical components are used to realize the basic functions of the control box assembly. The housing provides a mounting base for the electrical components and can protect them. The housing has a mounting cavity and an opening communicating with the mounting cavity. The electrical components can be placed in the mounting cavity through the opening. The cover is connected to the housing and covers the opening to form a relatively closed mounting cavity. Multiple protrusions are provided on the outer surface of the cover, which can improve the structural strength of the cover. When the electrical components are working, they generate a lot of heat. This heat heats the air in the mounting cavity to a higher temperature than the air outside the housing, thereby forming air convection between the inside and outside of the housing through the first and second through holes, thus achieving heat dissipation. Since adjacent protrusions are spaced apart to form a drainage channel, and the second through hole is located in the drainage channel, the convective air can be guided by the drainage channel, thereby promoting the circulation of air between the inside and outside of the housing through the second through hole, thus further improving the heat dissipation effect of the control box assembly and thus increasing the service life of the control box assembly. Therefore, the technical solution of this application can effectively solve the problem of poor heat dissipation of control boxes in related technologies. Attached Figure Description

[0028] 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. The following description of at least one exemplary embodiment is merely illustrative and is in no way intended to limit the present utility model or its application or use. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model.
[0029] like Figures 1 to 6 As shown, this application provides a control box assembly. An embodiment of the control box assembly of this application includes: a housing 10, an electrical component 20, and a cover 30; the housing 10 has a mounting cavity and an opening communicating with the mounting cavity, and a first through hole 11 is provided on the housing 10; the electrical component 20 is disposed in the mounting cavity; the cover 30 is connected to the housing 10 and covers the opening, and a plurality of protrusions 31 are provided on the outer surface of the cover 30, with two adjacent protrusions 31 spaced apart to form a drainage channel 32, and a second through hole 33 located in the drainage channel 32 is also provided on the cover 30.
[0030] Using the technical solution of this embodiment, the electrical component 20 is used to realize the basic functions of the control box assembly. The housing 10 provides a mounting base for the electrical component 20 and can protect the electrical component 20. The housing 10 has a mounting cavity and an opening communicating with the mounting cavity. The electrical component 20 can be placed in the mounting cavity through the opening. The cover 30 is connected to the housing 10 and covers the opening to form a relatively closed mounting cavity. Multiple protrusions 31 are provided on the outer surface of the cover 30. The multiple protrusions 31 can improve the structural strength of the cover 30. When the electrical component 20 is working, it will generate more heat, which will be... The air inside the mounting cavity is heated to a higher temperature than the air outside the housing 10, thereby creating air convection between the inside and outside of the housing 10 through the first through hole 11 and the second through hole 33, which serves to dissipate heat. Since adjacent protrusions 31 are spaced apart and form a drainage channel 32, and the second through hole 33 is located within the drainage channel 32, the convective air can be guided by the drainage channel 32, thus promoting airflow between the inside and outside of the housing 10 through the second through hole 33. This further improves the heat dissipation effect of the control box assembly, thereby extending its service life. Therefore, the technical solution of this embodiment can effectively solve the problem of poor heat dissipation in control boxes in related technologies.
[0031] like Figures 1 to 6As shown, there are multiple second through holes 33, which are spaced apart along the extension direction of the drainage channel 32. Specifically, the multiple second through holes 33 can better facilitate the airflow inside and outside the housing 10, thereby ensuring the heat dissipation effect of the control box assembly. The multiple second through holes 33 arranged spaced apart along the extension direction of the drainage channel 32 can ensure that the flowing air can be guided by the drainage channel 32, and thus circulate inside and outside the housing 10 through the second through holes 33.
[0032] like Figures 1 to 6 As shown, the raised strip 31 includes a first raised strip segment 311 and a second raised strip segment 312 connected to each other, and the first raised strip segment 311 and the second raised strip segment 312 are set at an included angle. Specifically, by setting the first raised strip segment 311 and the second raised strip segment 312, the raised strip 31 forms a structure similar to a zigzag line. Compared with setting a straight raised strip on the cover 30, the zigzag raised strip 31 is more aesthetically pleasing and has a larger coverage area than the straight raised strip, thus further strengthening the structural strength of the cover 30.
[0033] like Figures 1 to 6 As shown, the second through hole 33 is located within the area of the electrical component 20 projected onto the cover 30. Specifically, since the electrical component 20 is the main heat-generating element of the control box assembly, meaning the air temperature around the electrical component 20 is higher, placing the second through hole 33 within the area of the electrical component 20 projected onto the cover 30 makes the second through hole 33 closer to the electrical component 20, thereby improving the heat dissipation effect of the control box assembly.
[0034] like Figures 1 to 6 As shown, the control box assembly has a cuboid structure. The housing 10 includes a base plate 12, side plates 13, and end plates 14. The base plate 12 extends along the length of the cuboid structure, and the side plates 13 are connected to both sides of the base plate 12. The base plate 12, side plates 13, and cover 30 form an end opening communicating with the mounting cavity. The end plate 14 is detachably installed on the end opening. Specifically, in this embodiment, the control box assembly is connected to a frame, which forms the basis of the LED cabinet. The frame typically includes several crossbeams and vertical beams. When the LED cabinet is mounted on a wall or on a stand, the vertical beam extends vertically, and the control box assembly also extends vertically and is connected to a vertical beam. The control box assembly is installed on the side of the vertical beam, the cover 30 is located on the front side, the bottom plate 12 is located on the rear side, and the side plate 13 is located between the cover 30 and the bottom plate 12. There are two side plates 13, one of which is connected to the vertical beam. There are also two end plates 14, located at the upper and lower ends respectively. The end plates 14 are detachably installed on the end openings, so that the electrical components 20 can be easily installed into the mounting cavity.
[0035] like Figures 1 to 6As shown, there are multiple first through holes 11, which are disposed on the end plate 14. With this arrangement, since one end plate 14 is at the top, the heated air rises and flows to the outside of the housing 10 through the first through holes 11, while the relatively cooler air outside flows to the inside of the housing 10 through the second through holes 33 under the guidance of the drainage channel 32, thereby promoting air circulation inside and outside the housing 10 and enhancing the heat dissipation performance of the control box assembly.
[0036] like Figures 1 to 6 As shown, a first mounting base 34 is provided on the cover 30, and a second mounting base 15 is provided between the bottom plate 12 and the side plate 13. The control box assembly also includes a first fastener and a second fastener. The first fastener passes through the end plate 14 and the first mounting base 34, and the second fastener passes through the end plate 14 and the second mounting base 15. Specifically, both the first fastener and the second fastener are bolt structures, which can securely connect the end plate 14 to the cover 30 and the housing 10.
[0037] like Figures 1 to 6 As shown, the control box assembly also includes a first circuit board 41 and a second circuit board 42 disposed within the mounting cavity. The first circuit board 41 is connected to the inner side of the cover 30, and the second circuit board 42 is connected to the inner side of the base plate 12. The electrical component 20 includes a control module and a power module. The control module is disposed on the first circuit board 41, and the power module is disposed on the second circuit board 42. Specifically, by disposing of the control module and the power module on the first circuit board 41 and the second circuit board 42 respectively, the arrangement of the electrical component 20 becomes more rational.
[0038] like Figures 1 to 6 As shown, a connecting lug 141 is provided on the side of the end plate 14 extending along the thickness direction of the cuboid structure. Specifically, the connecting lug 141 enables the control box assembly to be connected to the frame.
[0039] Furthermore, the cover 30 is made of plastic. Plastic materials have good insulation properties and are relatively lightweight, while also providing a certain degree of protection and durability. Specifically, the plastic material can be polyethylene (PE), polypropylene (PP), polyvinyl chloride (PVC), or polycarbonate (PC). Polyethylene (PE) is characterized by its resistance to chemical corrosion, good electrical insulation, good flexibility, and low density; polypropylene (PP) is characterized by its resistance to chemical corrosion, good heat resistance, high strength, and light weight; polyvinyl chloride (PVC) is characterized by its resistance to chemical corrosion, good electrical insulation, and good processability; and polycarbonate (PC) is characterized by its high transparency, strong impact resistance, and good temperature resistance.
[0040] Furthermore, the shell 10 is made of metal. The metal material can be carbon steel, stainless steel, aluminum alloy, copper alloy, or titanium alloy. Carbon steel is characterized by high strength, low cost, and good machinability; stainless steel is characterized by good corrosion resistance, high strength, and good machinability; aluminum alloy is characterized by light weight, high strength, corrosion resistance, and good machinability; copper alloy is characterized by good electrical and thermal conductivity and corrosion resistance; and titanium alloy is characterized by high strength, corrosion resistance, light weight, and high temperature resistance.

The aforementioned control box assembly effectively solves the problem of poor heat dissipation in the control box in related technologies, and the LED enclosure with the aforementioned control box assembly also has the aforementioned advantages. Specifically, the LED enclosure further includes LED modules disposed on the front side of the frame, the LED modules being spaced apart from the control box assembly, and the side plate 13 of the control box assembly being attached to the frame (specifically, the side of the vertical beam mentioned above).
[0042] This application also provides an LED display device, which includes multiple LED cabinets, wherein the LED cabinets are those described above. The aforementioned LED cabinets effectively solve the problem of poor heat dissipation in the control box in related technologies, and the LED display device with the aforementioned LED cabinets also has the aforementioned advantages.
