Therefore, many LED display screens are designed with ventilation structures to facilitate air ventilation. When there is wind, it can dissipate heat better. However, the two sides of this type of display screen do not have ventilation and heat dissipation functions, making the heat dissipation effect weak.

[0003] After searching, the Chinese patent document (authorization announcement number CN220709884U) discloses a ventilated and light-proof grille display screen, including a screen plate, a ventilated slot inside the screen plate, a strip plate fixedly arranged at the bottom end of the screen plate, a connecting rod fixedly arranged between the inner sides of one end of the strip plate, a sleeve fixedly arranged at the bottom end of the connecting rod, a first magnetic patch fixedly arranged inside the sleeve, a slot plate, a black filter plate and a column block fixedly arranged at the top end of the cover shell, and a fin fixedly arranged inside the cover shell. The utility model forms a ventilated and light-proof structure of a highway grille display screen through ventilated slots, strip plates, connecting rods, sleeves, first magnetic patches, cover shells, slot plates, black filters, columns, fins, assembly slot plates, round covers and second magnetic patches. The ventilated structure is designed to facilitate air ventilation, and when there is wind, it can dissipate heat better, but the two sides of this display screen do not have ventilation and heat dissipation functions, making the heat dissipation effect weak. Utility Model Content

[0004] The utility model aims to provide a LED display screen which is air-permeable and light-proof, so as to solve the problems raised in the background technology.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: an air-permeable and light-proof LED display screen, comprising a mounting shell, a plurality of transverse support plates connected to the inner wall of the mounting shell, and a plurality of display units connected to the side of the transverse support plates, the inner wall of the mounting shell is also connected to an inner light-blocking plate and an outer light-blocking plate, and the sides of the inner light-blocking plate and the outer light-blocking plate are both provided with a plurality of ventilation channels that realize air-permeability and light-proof;

[0006] Multiple rectangular channels are opened on both sides of the installation shell, and multiple oblique connecting plates corresponding to the positions of the rectangular channels are installed on both sides of the installation shell. Two triangular connecting plates are connected between the oblique connecting plates and the installation shell, and the outer periphery of the installation shell and the oblique surfaces of the oblique connecting plates are connected with oblique light-blocking plates that achieve air permeability but no light transmission.

[0007] As a preferred embodiment, the inner wall of the rectangular channel of the mounting shell is detachably connected with a filter frame, and the inner wall of the filter frame is connected with a filter net.

[0008] As a preferred embodiment, the ventilation channels of the inner light baffle and the outer light baffle are staggered, the size of the ventilation channel is smaller than the size of the transverse support plate, and the position of the ventilation channel of the inner light baffle corresponds to the position of the transverse support plate.

[0009] As a preferred embodiment, the inner wall of the mounting shell is further connected with an inner light-transmitting plate and an outer light-transmitting plate made of transparent material, and the sides of the inner light-transmitting plate and the outer light-transmitting plate are both provided with a plurality of vertical channels.

[0013] Compared with the prior art, the technical effects and advantages of the utility model are as follows:

[0014] When the ventilated and light-proof LED display screen is in use, if there is wind on both sides, the air passes through the gap between the two oblique light shielding plates and enters the rectangular channel of the installation shell, and then is discharged from other positions where the air can be discharged. The flowing air takes away part of the heat generated by the operation of the LED display screen. If there is wind at the front or back, the ventilated design can enable the flowing air to take away part of the heat generated by the operation of the LED display screen. If there is no wind, the fan can be turned on for exhaust and heat dissipation.

[0015] When the LED display screen that is air-permeable and light-proof is used, if it encounters rainy and snowy weather, the outer shell, the oblique connecting plate, the outer light-transmitting plate and the outer light-blocking plate are installed to jointly block the display unit, so that the display unit can be protected. The vertical channels of the inner light-transmitting plate and the outer light-transmitting plate are staggered, so that the possibility of rain and snow affecting the display unit is reduced when the air is ventilated. The ventilation channels of the inner light-blocking plate and the outer light-blocking plate are staggered to achieve air-permeability and light-proof. The design of the two oblique light-blocking plates can also play the role of air-permeability and light-proof.

[0025] In the following description, a large number of specific details are given to provide a more thorough understanding of the utility model. However, it is obvious to those skilled in the art that the utility model can be implemented without one or more of these details. In other examples, in order to avoid confusion with the utility model, some technical features known in the art are not described.

[0026] Unless otherwise defined, the directions of up, down, left, right, front, back, inside and outside involved in this document are based on the directions of up, down, left, right, front, back, inside and outside in the figures shown in the present utility model, and are explained here together.

[0027] The connection method can be bonding, welding, bolt connection, etc., depending on actual needs.

[0028] See also Figures 1 to 5As shown, the present embodiment includes an installation shell 1, a plurality of transverse support plates 2 connected to the inner wall of the installation shell 1 and a plurality of display units 3 connected to the side of the transverse support plate 2. The display unit 3 is connected to an external device to form a display structure with a display function. The inner wall of the installation shell 1 is also connected to an inner light baffle plate 4 and an outer light baffle plate 5. When in use, if rainy or snowy weather occurs, the installation shell 1, the oblique connecting plate 6, the outer light-transmitting plate 12 and the outer light baffle plate 5 are jointly blocked to protect the display unit 3. The sides of the inner light baffle plate 4 and the outer light baffle plate 5 are provided with a plurality of ventilation channels that are air-permeable but not light-permeable. The ventilation channels of the inner light baffle plate 4 and the outer light baffle plate 5 are staggered to achieve air-permeable but not light-permeable. The size of the ventilation channel is smaller than the size of the transverse support plate 2. The position of the ventilation channel of the inner light baffle plate 4 is corresponding to the position of the transverse support plate 2. If there is wind in the front or back, the ventilation design of the ventilation channel and the ventilation frame 13 can allow the flowing air to take away part of the heat generated by the operation of the LED display screen.

[0029] A plurality of rectangular channels are provided on both sides of the installation shell 1, and a plurality of oblique connecting plates 6 corresponding to the positions of the rectangular channels are installed on both sides of the installation shell 1. Two triangular connecting plates 7 are connected between the oblique connecting plates 6 and the installation shell 1. The outer periphery of the installation shell 1 and the oblique surfaces of the oblique connecting plates 6 are connected with oblique light-blocking plates 8 for achieving air permeability but no light transmission. The design of the two oblique light-blocking plates 8 can also play the role of air permeability and no light transmission. If there is wind on both sides, the air passes through the gap between the two oblique light-blocking plates 8, enters the rectangular channel of the installation shell 1, and discharges from other positions where air can be discharged. The flowing air takes away part of the heat generated by the operation of the LED display screen.

[0030] The inner wall of the rectangular channel of the mounting housing 1 is detachably connected with a filter frame 9, and the inner wall of the filter frame 9 is connected with a filter screen 10 to reduce the influence of dust.

[0031] The inner wall of the mounting shell 1 is also connected with an inner light-transmitting plate 11 and an outer light-transmitting plate 12 made of transparent material. If the display unit 3 has a waterproof function, a waterproof shell can be provided by itself. The inner light-transmitting plate 11 and the outer light-transmitting plate 12 can be removed to avoid affecting heat dissipation. Multiple vertical channels are provided on the sides of the inner light-transmitting plate 11 and the outer light-transmitting plate 12. The vertical channels of the inner light-transmitting plate 11 and the outer light-transmitting plate 12 are staggered. The vertical channels of the inner light-transmitting plate 11 and the outer light-transmitting plate 12 are staggered, which reduces the impact of rain and snow on the display unit 3 when ventilated.

[0032] The side of the outer light baffle 5 is connected to multiple ventilation frames 13 corresponding to the position of the ventilation channel. The ventilation frames 13 are set at an angle. The inner wall of the ventilation frame 13 is connected to a dustproof net 14 and a fan 15, and the fan 15 is above the dustproof net 14. If it is a windless environment, turn on the fan 15 to exhaust air and dissipate heat.

[0033] The display unit 3 and the fan 15 are both conventional instruments, and their working principles, sizes and models are irrelevant to the problems solved by the present application, so they will not be described in detail. The control method of the present invention is controlled by a controller, and the control circuit of the controller can be realized by simple programming by technicians in this field. The provision of power is also common knowledge in this field, and the present invention is mainly used to protect mechanical devices, so the present invention will no longer explain the control method and circuit connection in detail.

[0034] How it works

[0035] When the display unit 3 is working normally, if there is wind on both sides, the air passes through the gap between the two oblique light shielding plates 8 and enters the rectangular channel of the mounting housing 1, and then the air is discharged from other positions where the air can be discharged. The flowing air takes away part of the heat generated by the operation of the LED display. If there is wind at the front or back, the ventilation design of the ventilation channel and the ventilation frame 13 can make the flowing air take away part of the heat generated by the operation of the LED display. If there is no wind, the fan 15 can be turned on to extract air and dissipate heat.

[0036] During use, if encountering rainy or snowy weather, the outer shell 1, the oblique connecting plate 6, the outer light-transmitting plate 12 and the outer light-blocking plate 5 are installed for joint blocking, which can protect the display unit 3. The vertical channels of the inner light-transmitting plate 11 and the outer light-transmitting plate 12 are staggered. When ventilating, the influence of rain and snow on the display unit 3 is reduced. The ventilation channels of the inner light-blocking plate 4 and the outer light-blocking plate 5 are staggered to achieve ventilation without light transmission. The design of the two oblique light-blocking plates 8 can also play the role of ventilation without light transmission.
