[0027] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. The following description of at least one exemplary embodiment is actually only illustrative and is by no means a limitation on the utility model and its application or use. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.

[0028] like Figures 1 to 5As shown, an embodiment of the utility model provides a box body, which includes a box body 10 and an air guide member 20. The box body 10 has a top plate 11, a bottom plate 12 and a side plate 13 connected between the top plate 11 and the bottom plate 12. The top plate 11, the bottom plate 12 and the side plate 13 surround a component accommodating cavity 14. The bottom plate 12 is provided with a first air guide port 121 connecting the component accommodating cavity 14 and the outside of the box body 10. The side plate 13 is provided with a second air guide port 131. One end of the second air guide port 131 is connected to the outside of the box body 10. An air guide channel 15 is provided inside the top plate 11 and the side plate 13. The other end of the second air guide port 131 is connected to the component accommodating cavity 14 through the air guide channel 15. The air guide member 20 is provided at the first air guide port 121 or the second air guide port 131 or the air guide channel 15, so that air can flow between the first air guide port 121, the component accommodating cavity 14 and the second air guide port 131.

[0029] The technical solution of the utility model is applied, and the box body includes a box body 10 and an air guide 20. By setting the air guide 20 at the first air guide port 121 or the second air guide port 131 or the air guide channel 15, the air flow enters from one of the first air guide port 121 and the second air guide port 131 by utilizing the air guide capacity of the air guide 20, flows through the component accommodating cavity 14 and the air guide channel 15, and then flows out from the other of the first air guide port 121 and the second air guide port 131, forming a circulating flow of air flow. Moreover, when flowing through the component accommodating cavity 14, the heat generated by the LED module and the components in the component accommodating cavity 14 can be taken away to cool the interior of the box body. Since the first air guide port 121 is arranged on the bottom plate 12 and the air guide channel 15 is arranged inside the top plate 11 and the side plate 13, when the airflow flows, it flows along the top plate 11 and the bottom plate 12 through the entire component accommodating cavity 14. The airflow has a larger flow range and can take away all the heat in the component accommodating cavity 14, so that the heat dissipation effect is better.

[0030] The air guide member 20 may be disposed at one of the first air guide port 121 , the second air guide port 131 and the air guide channel 15 , or at any two of them, or at all three of them.

[0031] It should be noted that, since the first air guide port 121 is disposed on the bottom plate 12 and the second air guide port 131 is disposed on the side plate 13 , there is no possibility that rainwater enters the box through the first air guide port 121 and the second air guide port 131 .

[0032] Furthermore, any one of the first air guide port 121 and the second air guide port 131 may serve as an air inlet to allow air to flow in.

[0033] In this embodiment, the components disposed in the component accommodating cavity 14 include a power supply and a control card, etc. When the airflow flows through the component accommodating cavity 14, the heat generated by the power supply and the control card can be diluted to reduce the internal temperature, thereby achieving a cooling effect.

[0034] like Figure 2 As shown, the first air guide port 121 is an air inlet, and a dustproof net 122 is provided at the air inlet. The dustproof net 122 can filter dust in the air to prevent dust from entering the box body, so as to keep the box body clean.

[0035] Of course, a dustproof net may also be provided at the second air guide port 131 .

[0036] like Figure 2 As shown, the bottom plate 12 is provided with a groove 123, the groove 123 extends toward the top plate 11, the dustproof net 122 is covered at the groove 123, and the first air guide 121 includes a plurality of air inlet holes arranged in an array on the bottom plate 12, and the plurality of air inlet holes are arranged corresponding to the dustproof net 122. With the above structural design, the recessed design of the groove 123 can prevent rainwater from flowing back into the box, and with the effect of the dustproof net 122, the cold air entering the box is basically dust-free and rain-free.

[0037] like Figure 2 As shown, the air guide channel 15 includes a first channel 151 and a second channel 152 that are connected. The first channel 151 is provided on the top plate 11 and extends in the same direction as the top plate 11, and the second channel 152 is provided on the side plate 13 and extends in the same direction as the side plate 13. With the above structure, the airflow flows downward from the first channel 151 to the second channel 152 and flows out through the second air guide port 131 to form a downward air outlet, which can well prevent the backflow of rainwater and play a better waterproof role.

[0038] The first channel 151 is located above the second channel 152 .

[0039] Furthermore, the air guide channel 15 adopts a closed design, and the second air guide port 131 is located at the side of the box body to form a downward air outlet.

[0040] like Figure 4 As shown, the side plate 13 includes two vertical plates 132 and a cover plate 133. The two vertical plates 132 are arranged opposite to each other, each vertical plate 132 is connected between the end of the top plate 11 and the corresponding end of the bottom plate 12, and the cover plate 133 is covered on the top plate 11, the bottom plate 12 and the rear side of the two vertical plates 132. The second channel 152 and the second air guide port 131 are both arranged on the vertical plates 132. The top plate 11, the bottom plate 12, the two vertical plates 132 and the cover plate 133 together form a component accommodating cavity 14. The side plate 13 adopting the above structure has the advantages of simple structure and easy processing.

[0041] The second channel 152 and the second air guide port 131 may be disposed on the vertical plate 132 or on the cover plate 133 as long as the flow of air is not hindered.

[0042] like Figure 2 and Figure 4 As shown, the air guide 20 includes two exhaust fans, which are arranged at intervals in the air guide channel 15 along the extension direction of the top plate 11. The two vertical plates 132 are each provided with a second air guide port 131, and the air guide channel 15 is connected to the component accommodating cavity 14 and the two second air guide ports 131. The two exhaust fans can quickly extract the hot air in the box to guide the hot air to the outside to dissipate heat for the component accommodating cavity 14 and the LED module.

[0043] like Figure 2 As shown, the inner wall of the second air guide port 131 is provided with an arc-shaped protrusion 16, and the arc-shaped protrusion 16 is located on the side of the second air guide port 131 close to the top plate 11. The arc-shaped protrusion 16 can form a hidden handle, which is convenient for the operator to lift and carry the box.

[0044] In this embodiment, arc-shaped protrusions 16 are provided at the two second air guide ports 131 .

[0045] like Figure 1 As shown, the box body also includes a box cover 30 which can be opened and closed and is covered on the box body 10, and the box cover 30 has a hollow structure. By setting the box cover 30, the LED module can be supported, and by opening the box cover 30 from the box body 10, the post-maintenance of the LED module can be achieved.

[0046] In this embodiment, the top of the box cover 30 and the box body 10 are provided with hinged joints, and the bottom of the box cover 30 can be opened relative to the bottom of the box body 10. And the bottom of the box cover 30 and the box body 10 are provided with locking members to lock the box cover 30 and the box body 10, so that the box cover 30 can form a whole with the box body 10.

[0047] The box cover 30 and the cover plate 133 are respectively arranged on two sides of the top plate 11 .

[0048] The hollow structure of the box cover 30 can allow the airflow to contact the rear side of the LED module to dissipate heat from the LED module.

[0049] like Figure 1 As shown, the box body also includes a retractable support rod 17, and the two ends of the support rod 17 are respectively hinged to the box body 10 and the box cover 30. By extending the support rod 17, the box cover 30 can be opened relative to the box body 10 to achieve post-maintenance of the LED module. By shortening the support rod 17, the box cover 30 can be buckled on the box body 10.

[0050] Another embodiment of the present application provides an LED display device, which includes an LED module and a box, wherein the LED module is arranged on the front side of the box, and the box is the box provided above. By using the box, when flowing through the component accommodating cavity 14, the heat generated by the LED module and the components in the component accommodating cavity 14 can be taken away to cool down the interior of the box. Since the first air guide port 121 is arranged on the bottom plate 12, and the air guide channel 15 is arranged inside the top plate 11 and the side plate 13, when the airflow flows, it flows along the top plate 11 and the bottom plate 12 through the entire component accommodating cavity 14, and the flow range of the airflow is larger, which can take away all the heat in the component accommodating cavity 14, so that the heat dissipation effect is better.

[0051] Specifically, air flows from the outside into the component accommodating cavity 14 through the first air duct 121, dissipates heat to the components in the component accommodating cavity 14, and dissipates heat to the LED module, and the hot air is drawn out of the component accommodating cavity 14 through the exhaust fan and introduced into the air guide channel 15, and the hot air flows along the air guide channel 15 and flows out of the box from the second air duct 131, thereby achieving the effect of heat dissipation of the box.

[0052] In addition, it should be noted that the use of terms such as "first" and "second" to limit components is only for the convenience of distinguishing the corresponding components. If not otherwise stated, the above terms have no special meaning and therefore cannot be understood as limiting the scope of protection of the utility model.

[0053] The above description is only the preferred embodiment of the utility model, and is not intended to limit the utility model. For those skilled in the art, the utility model can have various modifications and changes. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
