[0032] 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.

[0033] like Figures 1 to 4As shown, this application provides a protective housing. An embodiment of the protective housing includes: a mounting plate, electrical components, a surrounding plate 10, a first flange 20, and a cover 30. The electrical components are connected to the mounting plate. The surrounding plate 10 surrounds the outside of the electrical components, and the mounting plate is connected to the first side of the surrounding plate 10 in the front-rear direction. The first flange 20 is connected to the top plate 11 of the surrounding plate 10, and the first flange 20 is located on the second side of the surrounding plate 10 in the front-rear direction. The first flange 20 is spaced apart from the side plates 12 of the surrounding plate 10 and located away from the mounting plate 30. On one side of the plate, a mounting gap is formed between the first flange 20 and the side plate 12; a cover 30 is disposed on the second side of the enclosure 10 and covers the electrical components. The upper end of the cover 30 is inserted into the mounting gap. The cover 30 includes a cover plate 31 and a second flange 32. The lower end of the cover plate 31 is spaced apart from the bottom plate 13 of the enclosure 10 or from the mounting plate and forms a clearance gap 14 for the first connecting wire to pass through. The second flange 32 is connected to the side of the cover plate 31 and extends toward the first side of the enclosure 10. The second flange 32 is located on the outside of the side plate 12.

[0034] Using the technical solution of this embodiment, the electrical component is connected to the mounting plate; the enclosure 10 surrounds the outside of the electrical component, and the mounting plate and the cover 30 are respectively disposed on both sides of the enclosure 10 in the front-back direction. The mounting plate, the cover 30, and the enclosure 10 form a protective space for the electrical component; the first flange 20 is connected to the top plate 11 of the enclosure 10. The first flange 20 is located on the second side of the enclosure 10 in the front-back direction. The first flange 20 is spaced apart from the side plate 12 of the enclosure 10 and is located on the side of the side plate 12 away from the mounting plate. The first flange 20 and the side plate 12 form an installation gap. The upper end of the cover 30 is inserted into the installation gap. The first flange 20 can prevent water from entering the protective space from the connection between the cover 30 and the top plate 11; the cover 30 includes a cover plate 31 and a second flange 32. The second flange 32 is connected to the side of the cover plate 31 and extends towards the first side of the enclosure 10. The second flange 32 is located on the outside of the side plate 12. The second flange 32 can prevent water from entering the protected space from the connection between the cover plate 30 and the side plate 12. The lower end of the cover plate 31 is spaced apart from the bottom plate 13 of the enclosure 10 or the mounting plate to form a clearance gap 14 for the first connecting wire to pass through. Since the opening of the clearance gap 14 faces downward, water will not enter the protected space from the clearance gap 14. The first connecting wire can pass through the clearance gap 14 to the outside of the protective box. When the staff is maintaining the box, the cover plate 30 can be removed and the first connecting wire can be directly removed and passed through the hole. This reduces the operation of the staff to pass the first connecting wire through the hole and simplifies the maintenance operation. Therefore, the technical solution of this embodiment can effectively solve the problem in the related art of the difficulty in balancing waterproof requirements and convenient maintenance requirements.

[0035] It should be noted that the first connecting wire is the wire connecting the LED module and the electrical components. In this type of wire, both ends of the connecting wire are provided with connectors. Since the connectors themselves have a certain size, in the related technology of setting holes in the protective box, it is not easy for workers to insert and exit the connectors through the holes. The connecting wires of this type are generally flat wires with a thickness of about 1mm. In this embodiment, the enclosure 10 includes a base plate 13, and the clearance 14 is formed between the base plate 13 and the cover plate 31. The width of the clearance 14 is about 3mm. In other embodiments, the enclosure may not include a base plate, and the clearance is formed between the mounting plate and the cover plate. Therefore, the enclosure does not necessarily have to be a ring structure formed by multiple plates connected end to end.

[0036] like Figures 1 to 4 As shown, the protective box also includes a third flange 40, which is located on the second side of the enclosure 10 and connected to the inner side of the side panel 12. The cover plate 31 is connected to the third flange 40. Specifically, the third flange 40 is connected to the inner side of the side panel 12 (that is, the side away from the second flange 32), and the arrangement of the third flange 40 allows the cover plate 31 to be connected to the enclosure 10 through the third flange 40. More specifically, the protective housing also includes a second captive screw 74 located on the lower end of the cover plate 31. The second captive screw 74 can be threadedly connected to the third flange 40. The lower end of the third flange 40 is provided with a connecting lug 41. The second captive screw 74 is connected to the cover plate 31. The second captive screw 74 connects the lower end of the cover plate 31 to the surrounding plate 10 by connecting with the connecting lug 41. Compared with the use of ordinary screws, the second captive screw 74 does not need to be removed from the cover plate 31, so the staff does not need to worry about losing the screw during maintenance. Compared with the solution of connecting the screw to the side plate, the connection of the second captive screw 74 to the third flange 40 allows the staff to turn the second captive screw 74 in the front and back direction, avoiding lateral operation.

[0037] like Figures 1 to 4 As shown, the enclosure 10 includes a base plate 13, and a clearance gap 14 is formed between the lower ends of the base plate 13 and the cover plate 31. The base plate 13 is provided with a clearance opening 131 to allow passage of the second connecting wire. Specifically, in this embodiment, the electrical component includes a HUB board, and the second connecting wire is a network cable connecting the HUB board and the external structure. The diameter of the network cable is about 7mm, which cannot pass through the clearance gap 14. Therefore, a relatively large clearance opening 131 is provided.

[0038] like Figures 1 to 4As shown, the first flange 20 includes a flange body 21 and a side flange 22. The flange body 21 is connected to the side of the top plate 11 away from the mounting plate. The side flange 22 is connected between the end of the top plate 11 and the end of the flange body 21 and extends downward. The side flange 22 is located outside the second flange 32. Specifically, the side flange 22 further shields the connection between the upper end of the cover plate 31 and the top plate 11, thereby preventing water from entering the protected space from this point. The flange body 21 and the side flange 22 work together to ensure the waterproof effect. Specifically, the protective box also includes a first captive screw 73 provided on the first flange 20. The first captive screw 73 can be threadedly connected to the upper end of the cover plate 31. The first captive screw 73 is provided on the flange body 21. Compared with the use of ordinary screws, the first captive screw 73 does not need to be removed from the flange body 21, so the staff does not need to worry about losing the screw during maintenance. There are multiple first non-detachable screws 73, and the multiple first non-detachable screws 73 are spaced apart along the extension direction of the flange body 21.

[0039] like Figures 1 to 4 As shown, the protective housing also includes a fourth flange 50 and a pad 60. The fourth flange 50 is located on the side of the base plate 13 away from the mounting plate and extends upward. The pad 60 is located in the middle of the fourth flange 50, and the cover plate 31 abuts against the pad 60. Specifically, the fourth flange 50 provides a mounting base for the pad 60, and the pad 60 supports the cover plate 31 to prevent it from deforming when subjected to pressure. There are also multiple second captive screws 74, which are spaced apart along the bottom edge of the cover plate 31, and some of the second captive screws 74 are threadedly connected to the pad 60.

[0040] like Figures 1 to 4 As shown, the protective housing also includes fasteners 71 and mounting flanges 72 connected to the first side of the enclosure 10. The fasteners 71 pass through the mounting flanges 72 and the mounting plate to connect the mounting plate and the enclosure 10. Specifically, the mounting flanges 72 are provided so that the enclosure 10 can be connected to the mounting plate, thereby allowing workers to install or remove the fasteners 71 from the front and rear directions, thus connecting or separating the enclosure 10 and the mounting plate.

[0041] like Figure 5As shown, this application also provides an LED display device, which includes a base 100, an LED module 200, and a protective housing. The base 100 includes a frame 101 and a rear shell 102 connected to the rear side of the frame 101. The protective housing is connected to the base 100, and the LED module 200 is connected to the front side of the frame 101. The protective housing is located between the rear shell 102 and the LED module 200. The protective housing described above effectively solves the problem in related technologies of the difficulty in simultaneously meeting waterproofing and maintenance requirements. LED display devices with the aforementioned protective housing also possess these advantages.

[0042] like Figure 5 As shown, the mounting plate of the protective box is formed on the rear shell 102, and a support rib 301 is provided on the front side of the cover plate 31 of the protective box. The rear side of the LED module 200 abuts against the support rib 301. Specifically, in this embodiment, the mounting plate of the protective box is formed on the rear shell 102, so there is no need to set an additional mounting plate. The surrounding plate 10 can be directly connected to the rear shell 102. The support rib 301 protrudes forward from the first captive screw 73 and the second captive screw 74, so that the support rib 301 can support the rear side of the LED module 200, ensuring the stability of the LED module 200 installation.
