[0020] As mentioned in the background technology, LED display screens are widely used in various outdoor scenes, such as commercial billboards, traffic sign screens, sports event screens, large screens in city squares, etc. In order to facilitate remote control, a variety of communication methods are usually used, such as WiFi, 4G / 5G networks, Bluetooth or dedicated wireless communication modules, etc. Therefore, LED display screens are usually equipped with wireless communication modules (such as antennas) to achieve remote communication. The signal transmission effect of the wireless communication module is crucial to the communication quality, so it is usually necessary to set the wireless communication module outside to ensure a good signal transmission environment. However, exposing the wireless communication module to the outside of the LED display screen is not only easily affected by the external environment (such as rain, dust, etc.), but also significantly affects the overall aesthetics of the display screen.

[0025] In this embodiment, the regularly arranged through holes 91 on the light emitting module 40 play a role in transparent visual effect. Since this technical solution uses a large number of LED light emitters, the heating of LED light emitters is a technical difficulty that is difficult to overcome in the entire industry, and these regularly arranged through holes just solve the problems of ventilation and heat dissipation.

[0026] In some embodiments, the control housing 10 includes a front housing 11 and a rear housing 12 , and the front housing 11 and the rear housing 12 sandwich one end of the support plate 30 where the control area 401 is set, and snap together to form a complete control housing 10 .

The support plate 30 includes a second fixing hole 301, and the second fixing hole 301 is directly opposite to the first fixing hole 211. The fixing member 60 passes through the first fixing hole 211 and the second fixing hole 301, and is used to fix the rear shell 12 and the support plate 30 together. The support plate 30 provides mechanical support for the LED display device. Figure 2 , Figure 6 As shown, the upper end of the rear shell 12 extends forward, that is, toward the direction of the light-emitting module 40, to form an inverted L-shaped clamping portion 205, the upper end of the inverted L-shaped clamping portion 205 is flush with the upper end of the rear shell 12, and the upper end of the inverted L-shaped clamping portion 205 extends forward for a certain length and then bends downward to extend for a certain length, thereby forming an inverted L-shaped structure. The back side of the support plate 30 faces the front end of the front shell 11 and is clamped in the gap between the front end of the rear shell 12 and the inverted L-shaped clamping portion 205. A first fixing hole 211 having the same position and shape is also provided on the front end surface of the rear shell 12 and the inverted L-shaped clamping portion 205, and a second fixing hole 301 is provided on the support plate 30. When the support plate 30 is clamped into the gap between the front end surface of the rear shell 12 and the inverted L-shaped clamping portion 205, the first fixing hole 211 is opposite to the second fixing hole 301, that is, at this time, the second fixing hole 301 on the support plate 30 corresponds to the first fixing hole 211 in front and behind. At this time, the fixing member 60 can be used to pass through the first fixing hole 211 and the second fixing hole 301 to fix the support plate 30 and the rear shell 12 together. At this time, the control area 401 is located in the gap between the support plate 30 and the front shell 11.

[0031] The front shell 11 can be consistent in length with the rear shell 12 , the front end surface of the front shell 11 is arranged on the front side of the support plate 30 , and the front shell 11 contacts the inverted L-shaped clamping portion 205 and closes the upper ends of the front shell 11 and the rear shell 12 .

[0032] Further, such as Figure 2 , Fig. 9 As shown, it also includes a lifting clamp block 80, the first plug-in portion 221 is provided with a first notch 222, the first notch 222 is located above the first fixing hole 211, the upper end surface of the rear shell 12 is also provided with a first insertion hole 201, the first insertion hole 201 is located directly behind the first notch 222, and the second plug-in portion 101 is provided with a second notch 102 directly facing the first notch 222. When the first plug-in portion 221 and the second plug-in portion 101 cooperate with each other, the first notch 221 and the second notch 102 are combined to form a The second insertion hole is formed, and the lifting clamp block 80 includes two fixing plates 81.

The two fixing plates 81 are respectively inserted into the first insertion hole 201 and the second insertion hole, and the third fixing hole 811 on the fixing plate 81 is opposite to the first fixing hole 211 and the second fixing hole 301. The fixing member 60 passes through the first fixing hole 211, the second fixing hole 301 and the third fixing hole 811, and is used to fix the rear shell 12, the support plate 30 and the lifting clamp block 80 together.

[0033] In this embodiment, by providing a hoisting clamp 80, the rear housing 12 and the support plate 30 are firmly fixed together to ensure the stability of the overall structure of the display device, prevent loosening, displacement or falling off during installation or operation, and adapt to hoisting scenarios.

[0034] In some embodiments, it also includes a photosensitive module 411, which is disposed in the control area 401 and connected to the control module 70; The control housing 10 is provided with a photosensitive hole 103 , and the photosensitive module 411 senses the ambient light through the photosensitive hole 103 and controls the light intensity of the LED light-emitting body according to the intensity of the ambient light.

[0035] In this embodiment, the photosensitive module 411 can adjust the brightness of the LED light according to the intensity of the ambient light. For example, if the ambient light is strong, the brightness of the LED light can be increased for display effect. If the ambient light is weak, the brightness of the LED light can be reduced.

[0036] For example, Figure 2 As shown, the photosensitive module 411 includes a brightness sensor 412, and the brightness sensor 412 extends from the control module 70 to the photosensitive hole 103 to obtain ambient light.

[0037] In some embodiments, a power supply 90 is further included, and the rear shell 12 and the inverted L-shaped clamping portion 205 are further provided with a wire hole 231, and the upper side of the support plate 30 includes a third notch 303. When the support plate 30 is clamped in the gap between the rear shell 12 and the inverted L-shaped clamping portion 205, the wire hole corresponds to the third notch 303; The power source 90 is disposed in the rear housing 12 and is connected to the control area 401 of the light emitting module 40 through the wire hole 231 to supply power to the light emitting module 40 .

[0038] The power supply 90 is arranged in the rear shell 12, and the power supply needs to be connected to the light-emitting module located on the front side of the support plate 30 through a line. Therefore, in this embodiment, the rear shell 12 and the inverted L-shaped clamping portion 205 are also provided with a wire hole 231, and the upper side of the support plate 30 includes a third notch 303. When the support plate is clamped in the gap between the rear shell 12 and the inverted L-shaped clamping portion 205, the wire hole 231 corresponds to the third notch 303, that is, a notch is set on the support plate 30, and the wire from the power supply 90 to the light-emitting module 40 is not blocked. The power supply can be connected to the control area 401 of the light-emitting module 40 through the wire hole 231 to supply power to the light-emitting module 40.

[0039] The rear end surface of the rear shell 12 may further include an installation port, and the installation port is used to install the power supply 90. The installation port can be provided to conveniently install and remove the power supply 90 according to needs.

[0040] Further, such as Figure 2 , Figure 5 as well as Figure 8 As shown, it also includes a rear cover 314, which is arranged on the back of the rear shell 12 to cover the installation port and improve the overall aesthetics. The rear cover 314 includes a plurality of heat dissipation holes 315 for dissipating heat for the power supply 90.

[0041] In the embodiment of the present application, the power supply 90 and the power supply circuit are arranged in the rear shell 12, which can reduce the exposed components and improve the overall aesthetics.

[0042] In some embodiments, the front shell 11 and the rear shell 12 can be hollow structures with openings at both ends. The control shell 10 also includes a side cover plate. The front shell 11 and the rear shell 12 are both hollow structures with openings at both ends. The side cover plates are arranged at the openings at both ends of the front shell 11 and the rear shell 12, and are used to fix the front shell 11 and the rear shell 12 together and close the openings at both ends of the front shell 11 and the rear shell 12.

[0043] The shape of the side cover plate 50 can be the same as the overall shape of the openings at both ends of the front shell 11 and the rear shell 12, and can tightly close the front shell 11. The side cover plate 50 is arranged at both ends of the front shell 11 and the rear shell 12, and covers the openings of the front shell 11 and the rear shell 12 at the same time, and is used to fix the front shell 11 and the rear shell 12 together, and close the openings at both ends of the front shell 11 and the rear shell 12.

[0044] For example, the side cover 50, the front shell 11 and the rear shell 12 include screw holes. When the side cover 50 is set at the two ends of the front shell 11 and the rear shell 12, some of the screw holes on the side cover 50 face the front shell 11, and the other part of the screw holes face the screw holes on the rear shell 12. At this time, screws can be used to fix the side cover 50 to the two ends of the front shell 11 and the rear shell 12.

[0045] Furthermore, for aesthetics, Figure 2 As shown, the screw holes on the side cover plate 50 can also be shielded. The side sealing plate 51 can be used to cover the side cover plate 50 to shield the screw holes on the side cover plate 50.

[0046] In this embodiment, by using the front shell 11 and the rear shell 12 as the shell of the LED display device, the front shell 11 and the rear shell 12 are both hollow structures with openings at both ends, and components (such as power supply, circuits, etc.) can be conveniently placed in the front shell 11 and the rear shell 12. The upper end surfaces of the front shell 11 and the rear shell 12 are in close contact and closed, and the side is closed by the side cover plate 50, and the wireless communication module 71 is arranged inside the shell. Since the material will not shield the wireless communication module 71 signal, even if the wireless communication module 71 is located in the shell, the normal communication function can still be ensured. At the same time, the control area of ​​the light-emitting module is designed in the gap between the support plate 30 and the front shell 11, and only the light-emitting area on the light-emitting module 40 is exposed to the outside, and other components can be arranged inside the front shell 11 and the rear shell 12. The present application avoids the exposure of components, and also makes the appearance more concise and beautiful, improves the integration and overall aesthetics of the LED display device, and the front shell, the rear shell, and the side cover are all made of materials that do not shield the wireless communication module. Even if the wireless communication module is arranged inside the control shell, it still does not affect the normal communication of the wireless communication module.

[0047] In some embodiments, a first limiting portion 501 and a second limiting portion 502 are further provided on the side cover plate. The first limiting portion 501 and the second limiting portion 502 can be two rectangular protrusions. The first limiting portion 501 is inserted between the support plate 30 and the rear shell 12, and the second limiting portion 502 is inserted between the support plate 30 and the front shell 11.

[0048] Further, such as Figure 7 As shown, the shapes of the front shell 11 and the rear shell 12 are both semi-rounded rectangles, and the overall shape of the openings at both ends is a rounded rectangle. The shape of the side cover 50 is the same as the overall shape of the openings at both ends. A plurality of third limiting portions 503 are also provided at the four rounded corners on the side cover 50. The third limiting portions are semicircular in shape. When the side cover 50 is installed at the openings at both ends of the front shell 11 and the rear shell 12, the third limiting portions 503 are respectively snapped into the rounded corners of the front shell 11 and the rear shell 12.

[0049] like Figure 1 , Figure 2 , Figure 3 , Figure 4 as well as Figure 5 As shown, the LED display device proposed in the embodiment of the present application places most of the components in the front shell 11 and the rear shell 12, and also places the wireless communication module 7171 between the front shell 11 and the light-emitting module 40, so that the overall appearance is simple and beautiful, and can also prevent external factors (rain, dust) from affecting the internal components.

[0050] In the embodiment of the present application, the wireless communication module 71 is arranged inside the control housing 10, and the control housing 10 is made of a material that does not shield the wireless communication module 71. Even if the wireless communication module 71 is located inside the control housing 10, normal communication function can still be ensured. At the same time, the present application arranges the control area 401 of the light-emitting module 40 and the control module 70 and the wireless communication module 71 arranged on the control area 401 inside the control housing 10, and only the light-emitting area 402 on the light-emitting module 40 is exposed to the outside, and other components (such as power supply, circuit, etc.) can be arranged inside the control housing 10.
