Description

Technical Field

[0001] This utility model relates to the field of LED display technology, specifically to a fully waterproof outdoor small-pitch LED display. Background Technology

[0002] Fine-pitch LED displays refer to indoor LED displays with an LED pixel pitch of P2.5 or less, mainly including LED display products with P2.5, P2.083, P1.923, P1.8, P1.667, P1.5, P1.25, and P1.0. With the improvement of LED display manufacturing technology, the resolution of traditional LED displays has been significantly improved.

[0003] As outdoor LED displays demand increasingly higher display quality, the market has an urgent need for outdoor small-pitch products. However, due to the complex and variable outdoor environment, outdoor displays require high levels of waterproofing, moisture resistance, and product reliability. On one hand, existing small-pitch LED display cabinets often have vents on the back for heat dissipation. During heavy rain and wind, rainwater can easily enter the cabinet through these vents, and the evaporation of this water can cause water ingress and short-circuit damage. On the other hand, rainwater or moisture can also enter the display through installation gaps, shortening the lifespan of outdoor small-pitch LED displays and resulting in resource waste.

[0004] In summary, there is an urgent need to design a fully waterproof outdoor small-pitch LED display screen that overcomes the aforementioned problems. Utility Model Content

[0008] The enclosure includes a front mounting shell and a rear mounting shell connected by bolts. A high-definition tempered glass panel is embedded on the front surface of the front mounting shell. L-shaped protective plates are respectively adhered to both sides of the inner wall of the high-definition tempered glass panel. One end of the L-shaped protective plate is fixedly connected to the inner wall of the front mounting shell, and the other end of the L-shaped protective plate is in contact with the front wall of the rear mounting shell.

[0009] A partition shell is fixedly connected to the middle of the front side wall of the rear mounting shell. A buffer air cavity is formed between the inner cavity of the partition shell and the rear mounting shell. After the front mounting shell and the rear mounting shell are installed and connected, the partition shell is sandwiched between the two L-shaped protective plates. The front side wall of the partition shell, the two L-shaped protective plates, the high-definition tempered glass panel and the top and bottom walls of the front mounting shell form a display screen mounting cavity. The display screen is installed in the display screen mounting cavity.

[0010] Both the partition shell and the front mounting shell have corresponding air vents at their lower ends. An exhaust fan is installed at the upper end of the air vent inside the partition shell, and a heat dissipation hole is provided on the front side wall of the partition shell.

[0011] The purpose of this utility model and the technical problems to be solved can be further achieved by the following technical measures.

[0012] Furthermore, the heat dissipation holes are opened at the lower end of the front side wall of the partition shell, and the number of heat dissipation holes and the number of exhaust fans are the same and they are arranged in a one-to-one correspondence.

[0013] Furthermore, a filter screen is provided on the side of the heat dissipation hole near the display screen mounting cavity, and a one-way valve is provided on the side of the heat dissipation hole near the buffer air cavity. Each heat dissipation hole is opened on the same side of the corresponding exhaust fan.

[0014] Furthermore, the one-way valve is a rubber plate that can cover the heat dissipation hole, one side of the rubber plate is hinged to one side of the heat dissipation hole, and an elastic pull member is provided at the hinge.

[0015] Furthermore, rubber pads are attached to the outer walls of both the L-shaped protective plate and the partition shell.

[0016] Furthermore, the outer perimeter of the box is also surrounded by a mouth-shaped enclosure, the bottom wall of the box is fixedly connected to the upper end of the bottom wall of the mouth-shaped enclosure, and the left, right and top walls of the mouth-shaped enclosure do not contact the box.

[0017] The bottom wall of the mouth-shaped enclosure has an opening corresponding to the air hole.

[0018] Furthermore, support columns are provided on both sides of the lower end of the mouth-shaped enclosure.

[0019] Compared with the prior art, the beneficial effects of this utility model are:

[0020] 1. This utility model discloses a fully waterproof outdoor small-pitch LED display screen. The cabinet is designed with a structure where front and rear mounting shells are bolted together. A high-definition tempered glass panel is embedded in the front of the front mounting shell to ensure viewing clarity. L-shaped protective plates are adhered to both sides of the inner wall of the high-definition tempered glass panel, and one end of each L-shaped protective plate is fixedly connected to the side wall of the front mounting shell, making the L-shaped protective plate, the high-definition tempered glass panel, and the front mounting shell a single integrated structure. A partition shell is connected in the middle of the rear mounting shell, forming a buffer air cavity between the partition shell and the rear mounting shell. After the front and rear mounting shells are bolted together, a display screen mounting cavity is formed between the partition shell, the two L-shaped protective plates, the high-definition tempered glass panel, and the top and bottom walls of the front mounting shell. The display screen is then installed... Inside the display installation cavity, it is easy for people to view the display content through the high-definition tempered glass panel. By opening heat dissipation holes and vents on the front and bottom walls of the partition shell, and installing an exhaust fan in the buffer air cavity, the heat emitted by the display screen can be drawn from the heat dissipation holes into the buffer air cavity and further discharged through the vents, effectively preventing rainwater from directly entering the display installation cavity through the heat dissipation vents. At the same time, the L-shaped protective plate and partition shell further shield the gap between the front and rear installation shells, effectively preventing rainwater or moisture from directly entering the display screen through the installation gaps in the display cabinet. This ensures the moisture-proof performance and good heat dissipation performance inside the display installation cavity, extending the lifespan of the outdoor small-pitch LED display screen and avoiding resource waste.

[0021] 2. The fully waterproof outdoor small-pitch LED display of this utility model, by setting filter screens and one-way valves in the heat dissipation holes, can prevent dust or large particles of foreign matter from entering the display installation cavity, thus ensuring the clarity of the display. At the same time, when the exhaust fan is not working and the pressure in the buffer air cavity is high due to excessive moisture, the one-way valve automatically closes, which can prevent moisture in the buffer air cavity from entering the interior of the display installation cavity through the heat dissipation holes, effectively improving the moisture-proof performance of the display installation cavity.

[0022] 3. The fully waterproof outdoor small-pitch LED display screen of this utility model, by setting an opening-shaped enclosure, can further prevent rainwater from directly contacting the gap between the front and rear mounting shells, thereby improving the rainproof and moisture-proof effect of the device and extending its service life.

[0037] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0038] Please see Figures 1 to 4 A fully waterproof outdoor small-pitch LED display screen, comprising:

[0039] The enclosure 1 and the display screen 2 installed inside the enclosure 1;

[0040] The housing 1 includes a front mounting shell 11 and a rear mounting shell 12 connected by bolts 13. A high-definition tempered glass panel 3 is embedded on the front surface of the front mounting shell 11 to ensure the clarity of the display screen. L-shaped protective plates 4 are respectively adhered to both sides of the inner wall of the high-definition tempered glass panel 3. One end of the L-shaped protective plate 4 is fixedly connected to the inner wall of the front mounting shell 11. After the front and rear mounting shells are installed by bolts 13, the other end of the L-shaped protective plate 4 contacts and connects to the front wall of the rear mounting shell 12. Before the front and rear mounting shells are connected, the L-shaped protective plate, the high-definition tempered glass panel and the front mounting shell are a whole structure.

[0041] A partition shell 5 is fixedly connected to the middle of the front side wall of the rear mounting shell 12. Before being installed with the front mounting shell 11, the rear mounting shell 12 and the partition shell 5 are an integral installation structure. Of course, for ease of maintenance, the partition shell 5 can be detachably connected to the rear mounting shell 12. A buffer air cavity 6 is formed between the inner cavity of the partition shell 5 and the rear mounting shell 12. After the front mounting shell 11 and the rear mounting shell 12 are installed and connected, the partition shell 5 is sandwiched between the two L-shaped protective plates 4. The front side wall of the partition shell 5, the two L-shaped protective plates 4, the high-definition tempered glass panel 3, and the top and bottom walls of the front mounting shell 11 form a display screen mounting cavity 7. The display screen 2 is installed in the display screen mounting cavity 7. The display screen 2 is pre-installed between the L-shaped protective plates 4 or pre-installed on the partition shell 5. People can see the content on the display screen 2 through the high-definition tempered glass panel 3. The display screen 2 is a small-pitch LED display screen.

[0042] Both the partition shell 5 and the front mounting shell 11 have corresponding vents 51 at their lower ends. An exhaust fan 8 is installed at the upper end of the vents 51 inside the partition shell 5, and a heat dissipation hole 52 is provided on the front side wall of the partition shell 5. Through the exhaust fan 8 inside the buffer air cavity 6, the heat emitted by the display screen 2 can be drawn from the heat dissipation hole 52 into the buffer air cavity 6, and further discharged through the vents 51, effectively preventing rainwater from directly reaching the interior of the display screen mounting cavity 7 through the heat dissipation vents. At the same time, the L-shaped protective plate 4 and the partition shell 5 further block the connection gap between the front and rear mounting shells, effectively preventing rainwater or moisture from directly entering the interior of the display screen through the mounting gap of the display screen cabinet.

[0043] Preferably, the heat dissipation holes 52 are opened at the lower end of the front side wall of the partition shell 5, and the number of heat dissipation holes 52 and the exhaust fan 8 are the same and are set in a one-to-one correspondence to improve the heat dissipation effect.

[0044] Preferably, a filter screen 53 is provided inside the heat dissipation hole 52 on the side near the display screen mounting cavity 7, and a one-way valve 54 is provided inside the heat dissipation hole 52 on the side near the buffer air cavity 6. Each heat dissipation hole 52 is located on the same side as its corresponding exhaust fan 8. The filter screen 53 can prevent dust or large particles of foreign matter from entering the display screen mounting cavity 7, ensuring the clarity of the display screen. When the exhaust fan 8 is working, the one-way valve 54 opens, with its opening facing the buffer air cavity 6, facilitating heat dissipation. At the same time, when the exhaust fan 8 is not working and there is a lot of water vapor and the pressure in the buffer air cavity 6 increases, the one-way valve 54 automatically closes, which can prevent water vapor in the buffer air cavity 7 from entering the interior of the display screen mounting cavity 7 through the heat dissipation hole 52, effectively improving the moisture-proof performance of the display screen mounting cavity 7.

[0045] Preferably, the one-way valve 54 is a rubber plate that can cover the heat dissipation hole 52. One side of the rubber plate is hinged to one side of the heat dissipation hole 52. An elastic pull member is provided at the hinge. The elastic pull member can be a torsion spring, a common tension spring, an elastic rope, etc.

[0046] Preferably, rubber pads 41 are attached to the outer walls of both the L-shaped protective plate 4 and the partition shell 5. After the front and rear mounting shells are installed, the rubber pads 41 can improve the sealing effect between the L-shaped protective plate 4 and the partition shell 5, as well as between the two and the front and rear mounting shells.

[0047] Preferably, the outer perimeter of the housing 1 is further surrounded by an opening-shaped enclosure 9, and the bottom wall of the housing 1 is fixedly connected to the upper end of the bottom wall of the opening-shaped enclosure 9. The left and right side walls and the top wall of the opening-shaped enclosure 9 do not contact the housing 1. The opening-shaped enclosure 9 can further prevent rainwater from directly contacting the installation gap between the front and rear mounting shells, thereby improving the rainproof and moisture-proof effect of the device and extending the service life of the device.

[0048] The bottom wall of the mouth-shaped enclosure 9 has an opening corresponding to the air hole 51 to facilitate ventilation.

[0049] Preferably, the lower ends of the mouth-shaped enclosure 9 are respectively provided with support columns 91 on both sides, which facilitates the installation of this device on the ground. Of course, the whole formed by the box and the mouth-shaped enclosure in this device can also be installed outdoors in other ways, such as by hanging, etc., which is not limited in this utility model.

[0050] The present invention has been further described above with reference to the embodiments, but the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present invention.
