Description

Technical Field

[0001] This application relates to the field of outdoor displays, and more particularly to an outdoor fixed-mount display with a high waterproof rating. Background Technology

[0002] Outdoor LED displays are densely packed with multiple LED lights. By controlling the LED lights to turn on and off, multiple LED lights of different colors can be lit simultaneously to form different colors, thus enabling the LED display to show high-definition dynamic graphics.

[0003] The mainstream structure of existing outdoor fixed LED displays mostly adopts the design of "sheet metal cabinet and module splicing". The cabinet frame is formed by bending sheet metal, and multiple LED modules are directly fixed to the cabinet frame with bolts. A control box is set on the cabinet frame, and a circuit board is set inside the control box. The circuit board is connected to the LED modules through wires. The circuit board can control the LED lights to switch on and off, so that the LED display can display the predetermined dynamic images.

[0004] The aforementioned technical solutions have the following drawbacks: when LED displays are installed outdoors, they are easily damaged by rainwater erosion, and repairs are time-consuming and labor-intensive. Utility Model Content

[0005] To improve the waterproof capability of LED displays, this application provides an outdoor fixed-mount high waterproof rating LED display.

[0006] This application provides an outdoor fixed high-waterproof display screen with the following technical solution: An outdoor fixed high-waterproof display screen includes multiple LED display modules, a cabinet control frame, and a control box assembly. The multiple LED display modules are mounted on the cabinet control frame. The control box assembly includes a control box bottom cover, a profile top cover, and a circuit driver board. The control box bottom cover is fixed to the cabinet control frame and is rotatably connected to the profile top cover. The circuit driver board is disposed inside the control box bottom cover. Waterproof adhesive strips are glued to the edge of the profile top cover to seal the gap between the control box bottom cover and the profile top cover.

[0007] By adopting the above technical solution, by setting an LED display module on the control frame of the enclosure, the control box assembly is electrically connected to the LED display module, thereby enabling the control box assembly to supply power to the LED display module and control the LED light switch. By installing the circuit driver board between the bottom cover of the control box and the top cover of the profile, the bottom cover of the control box and the top cover of the profile together cover the circuit driver board, which can reduce the probability of rainwater falling on the surface of the circuit driver board and damaging the circuit driver board.

[0008] Optionally, the bottom cover of the control box has multiple wire holes, and waterproof rubber rings are provided at the wire holes for contact with the control frame of the box.

[0009] By adopting the above technical solution, wire holes are opened on the bottom cover of the control box, allowing the wires on the circuit driver board to extend through the wire holes and connect to the LED display module. A waterproof rubber ring is installed on the bottom cover of the control box at the wire hole. When the bottom cover of the control box is fixed to the control frame of the enclosure by bolts, the waterproof rubber ring abuts against the control frame of the enclosure, which can reduce the probability of rainwater entering the bottom cover of the control box through the wire hole.

[0010] Optionally, a power cord / signal cord assembly is provided at the bottom of the control box cover, and a water drop column is provided on the lower side of the control box cover, the water drop column being a pipe structure.

[0011] By adopting the above technical solution, a power line / signal line assembly is installed on the lower side of the control box bottom cover, allowing the wires to pass through the control box bottom cover and be electrically connected to the circuit drive board. By installing a water dropper on the control box bottom cover, when there is water accumulation inside the control box bottom cover, the water can flow out through the water dropper, thus protecting the circuit drive board.

[0012] Optionally, the LED display module includes a face mask, a lamp board, and a metal base. The face mask and the metal base are respectively installed on both sides of the lamp board. The face mask has multiple through holes, through which the LEDs on the lamp board are exposed. The metal base is used for detachable connection with the housing control frame.

[0013] By adopting the above technical solution, grooves are created on the faceplate to protect the LED lights. When rainwater falls on the LED display module, it flows down along the grooves on the faceplate surface, reducing the chance of rainwater contacting the LED lights. By installing a metal base shell on the lamp plate, users can install bolts and other fasteners on the metal base shell to fix the LED display module to the housing control frame. Grooves are created on both the faceplate and the metal base shell, forming internal grooves when they are spliced ​​and fixed. By placing the lamp plate in the cavity between the faceplate and the metal base shell, the chance of the lamp plate contacting rainwater is reduced, improving the waterproofness of the LED display module.

[0014] Optionally, a knob locking assembly is rotatably connected to the metal base shell. The knob locking assembly includes a rotating shaft and a rotating handle. The rotating handle is fixed to the end of the rotating shaft. Multiple connection holes are provided on the housing control frame. The connection holes are of the waist hole structure. The rotating handle is used to insert into the connection holes and engage with the housing control frame.

[0015] By adopting the above technical solution, a knob locking assembly is set on the metal base shell, so that the rotating shaft is rotatably connected to the metal base shell. The rotating handle is set at the end of the rotating shaft and protrudes from the metal base shell. The user can insert the rotating handle into the connection hole and rotate the rotating handle to lock it on the cabinet control frame, so that the LED display module can be easily and quickly detachably connected to the cabinet control frame.

[0016] Optionally, the mask has knockout holes, the two ends of the rotating shaft have end holes, the lamp plate has through holes, and the ends of the rotating shaft are exposed through the through holes and knockout holes of the lamp plate.

[0017] By adopting the above technical solution, and by opening knockout holes in the mask, users can quickly open through holes in the mask, and the end face of the rotating shaft can be exposed through the knockout holes. Users can use tools to rotate the rotating shaft, and users can rotate and tighten the locking components on both sides of the LED display module, thereby facilitating the installation and maintenance of the LED display module.

[0018] Optionally, a limiting groove is provided on the metal bottom shell, and a limiting block is fixed at the end of the rotating shaft. The cross-section of the limiting groove is fan-shaped, and the limiting block is locked in the limiting groove.

[0019] By adopting the above technical solution, a limiting groove is opened on the metal bottom shell, and the limiting block is locked in the limiting groove. When the rotating shaft rotates on the metal bottom shell, the limiting groove restricts the rotation range of the rotating shaft, thereby allowing the handle to remain locked on the connecting hole, reducing the probability of the knob locking assembly disengaging from the control frame of the housing.

[0020] Optionally, a waterproof and breathable valve is provided on the metal base shell, which is used to connect the cavity between the mask and the metal base shell with the outside atmosphere.

[0021] By adopting the above technical solution, a waterproof and breathable valve is installed on the metal base shell and set as a one-way valve. When the lamp board is powered on, the surface of the lamp board heats up, making the temperature inside the cavity formed by the metal base shell and the mask higher. The waterproof and breathable valve can connect the cavity with the outside atmosphere, thereby reducing the pressure difference between the metal base shell and the mask and reducing the probability of deformation of the LED display module.

[0022] In summary, the beneficial technical effects of this application are as follows: 1. By setting an LED display module on the control frame of the enclosure, the control box assembly is electrically connected to the LED display module, thereby enabling the control box assembly to supply power to the LED display module and control the LED light switch. By installing the circuit driver board between the bottom cover of the control box and the top cover of the profile, the bottom cover of the control box and the top cover of the profile together cover the circuit driver board, which can reduce the probability of rainwater falling on the surface of the circuit driver board and damaging the circuit driver board. 2. By creating knockout holes in the face mask, users can quickly create through holes in the face mask, and the end face of the rotating shaft can be exposed through the knockout holes. Users can use tools to rotate the rotating shaft, and users can rotate and tighten the locking components on both sides of the LED display module, which facilitates the installation and maintenance of the LED display module. 3. By setting a waterproof and breathable valve on the metal base, and setting the waterproof and breathable valve as a one-way valve, when the lamp board is powered on, the surface of the lamp board heats up, making the temperature inside the cavity formed by the metal base and the mask higher. The waterproof and breathable valve can connect the cavity with the outside atmosphere, thereby reducing the pressure difference between the metal base and the mask, which can reduce the probability of deformation of the LED display module.

The lamp board 12 is a circuit board structure with multiple LEDs mounted on it. The faceplate 11 and the metal base 13 are respectively mounted on the two sides of the lamp board 12. The faceplate 11 is made of plastic and has multiple through holes through which the LEDs on the lamp board 12 are exposed, providing illumination. The faceplate 11 also protects the lamp board 12, and its surface has grooves to reduce the chance of rain damaging the LEDs. The metal base 13 is equipped with a knob locking assembly 14, which allows the metal base 13 to be detachably connected to the housing control frame 2, enabling the LED display module 1 to be easily and quickly installed and removed from the housing control frame 2.

[0038] Reference Figure 2A waterproof and breathable valve 15 is provided on the metal base shell 13. The metal base shell 13 is bonded and fixed to the face mask 11. Grooves are formed on the surfaces of the face mask 11 and the metal base shell 13, and the lamp board 12 is placed in the grooves. A closed cavity is formed between the metal base shell 13 and the lamp board 12. The wires of the lamp board 12 are placed in the cavity and extend through the metal base shell 13. The edge of the metal base shell 13 is sealed to the edge of the face mask 11, thereby improving the waterproof capability of the lamp board 12. The waterproof and breathable valve 15 can be set as a one-way valve. When the lamp board 12 is activated, the LED light illuminates and generates heat, which raises the temperature of the air in the cavity between the metal base shell 13 and the face mask 11. This can easily create a pressure difference between the cavity and the outside atmospheric pressure, causing the metal base shell 13 to be under greater pressure. By setting the waterproof and breathable valve 15, the cavity between the face mask 11 and the metal base shell 13 can be connected to the outside, and the air pressure in the cavity can be kept stable.
