[0030] The technical solutions of the present utility model will be further described below with reference to the accompanying drawings and through specific implementation manners.

[0031] The embodiment of the present utility model provides a structure 100 of an LED display screen.

[0032] Please refer to Figure 1 、 Figure 2 and Figure 3 , the structure 100 of the LED display screen includes:

[0033] A display screen module 110, which is used to display electronic image information;

[0034] An outer housing 120, which forms an internal space. The outer housing 120 is disposed around the display screen module 110 and is used to install the display screen module 110 in the outer housing 120; and

[0035] A heating component 130, the heating component 130 includes a hot air duct 131, a heating element 132, and a air supply device 133; the hot air duct 131 is disposed on the back of the display screen module 110 and installed in the internal space of the outer housing 120, the hot air duct 131 has ventilation holes 131a; the air supply device 133 heats the cold air from the outside through the heating element 132 and conveys the hot air to the back of the display screen module 110 through the ventilation holes 131a on the hot air duct 131; and

[0036] A heat preservation housing 140, the heat preservation housing 140 has a first ventilation hole 140a and a second ventilation hole 140b, the heat preservation housing 140 is disposed around the air supply device 133, the air supply device 133 sends the cold air from the outside into the hot air duct 131 through the first ventilation hole 140a; the heat preservation housing 140 is fixed to the outer housing 120 and communicates with the internal space of the outer housing 120 through the second ventilation hole 140b.

[0037] It can be understood that the technical solution of the present invention arranges a heating component 130 and a heat preservation housing 140 on the back of the display screen module. Specifically, the heating component 130 includes a hot air duct 131, a heating element 132, and an air supply device 133; the hot air duct 131 is disposed on the back of the display screen module 110 and installed in the internal space of the outer housing 120, the hot air duct 131 has ventilation holes 131a; the air supply device 133 heats the cold air through the heating element 132 and conveys the hot air to the back of the display screen module 110 through the ventilation holes 131a on the hot air duct 131, so as to achieve the effect of heating the display screen module and reduce the influence of the severe cold environment on the normal operation of the LED display screen 100.

[0038] It can also be understood that while heating the back of the display screen module, the heating component 130 can also heat the entire LED display screen 100, thereby avoiding the formation of ice condensation on the outside of the LED display screen 100 and reducing the influence on the display effect.

[0039] It should also be emphasized that the structure 100 of the LED display screen further includes a heat preservation housing 140. The main purpose of setting the heat preservation housing 140 is to keep the heated air warm and form a heat cycle inside the heat preservation housing 140 to reduce energy loss. Specifically, a first ventilation hole 140a and a second ventilation hole 140b are provided in the heat preservation housing 140. The setting of the first ventilation hole 140a forms an air inlet duct relative to the internal space of the outer housing 120, and the second ventilation hole 140b forms an air exhaust duct relative to the internal space of the outer housing 120. It can be understood that the hot air is discharged from the air exhaust duct, and the hot air forms a heat cycle inside the heat preservation housing 140, so that part of the air is directly sucked by the air supply device 133 into the internal space of the outer housing 120 for heating the display screen module. Therefore, the setting of the heat preservation housing 140 realizes the recycling of hot air and reduces energy loss.

[0040] As Figure 4 shown, in one embodiment, the hot air duct 131 includes a hot air main duct 1311 and a plurality of hot air branch ducts 1312; the ventilation holes 131a are provided in the hot air branch ducts 1312, and the hot air main duct 1311 is fixed to the display screen module 110; a plurality of the hot air branch ducts 1312 are communicated with the hot air main duct 1311.

[0041] The arrangement of the shown hot air branch ducts 1312 expands the heating area of the hot air duct 131, makes the inside of the display screen module heated evenly, and avoids local overheating and damage to the components on the display screen module.

[0042] As Figure 4 shown, in one embodiment, a plurality of the hot air branch ducts 1312 are horizontally arranged on the back of the display screen module 110. It can be understood that the horizontally arranged hot air branch ducts 1312 reduce the occupation of space, so that the internal arrangement of the LED display screen 100 is more compact.

[0043] Please refer to Figure 3 , in a specific embodiment, the hot air main duct 1311 is connected to a heating chamber 134, and the heating element 132 is arranged in the heating chamber 134; the air supply device 133 includes a fan 1331 and a driving member 1332;

[0044] The fan 1331 is arranged inside the heating chamber 134 and on a side far from the hot air main duct 1311, and the driving member 1332 is connected to the heating chamber 134 and is located outside the heating chamber 134;

[0045] The heating chamber 134 has an air extraction hole 134a for enabling the fan 1331 to suck outside air.

[0046] It is understandable that the arrangement of the heating chamber 134 can reduce heat loss and improve the heat transfer efficiency of the heating element 132. In addition, the drive element 1332 is arranged outside the heating chamber 134, which reduces the probability of the drive element 1332 overheating and failing.

[0047] Optionally, the heating element 132 is a heating wire. The driving element 1332 is a separately provided driving motor.

[0048] like Figure 3 As shown, it can also be understood that the setting of the heat preservation shell 140 protects the driving member 1332, and the setting of the heat preservation shell 140 can also play a role in preventing rain and snow. Specifically, the heat preservation shell also has a third air hole 140c, and the third air hole 140c is arranged toward the ground; the first air hole 140a is arranged close to the driving member 1332.

[0049] The first air hole 140a is arranged directly opposite to the driving motor, so that the first air hole 140a is closer to the heating element 132, reducing the probability of moisture in the air condensing into ice outside the air hole 140a. The third air hole 140c is arranged toward the ground, utilizing the principle of hot air rising and improving the recycling rate of hot air. On the other hand, the third air hole 140c is arranged to ensure good ventilation and heat dissipation inside the heat-insulating shell. When the internal space of the outer shell is overheated, the heating element 132 is closed to discharge the hot air in time, thereby avoiding overheating and damage to the display screen module 110.

[0050] Furthermore, a filter is provided on one side of the heat-insulating shell 140 close to the air hole 140a, and the filter is used to filter impurities in the air.

[0051] like Figure 2 As shown, in a specific embodiment, the LED display screen 100 further includes a heat preservation layer 150; the heat preservation layer 150 is arranged around the interior of the outer shell 120 and is arranged on a side of the hot air duct 131 away from the display module.

[0052] It can be understood that the setting of the heat insulation layer 150 is mainly to keep the temperature inside the outer casing 120 stable and slow down the heat loss. Optionally, the material of the heat insulation layer 150 is heat-conducting silica gel or foam plastic. As mentioned above, the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it; although the present invention has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements on some of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the spirit and scope of the technical solutions of the various embodiments of the present invention.
