[0001] This utility model belongs to the field of traffic display screen technology, and in particular to an LED traffic display screen. Background Technology

[0002] In the transportation sector, with the acceleration of urbanization and the continuous growth of traffic flow, the demand for efficient traffic management and information transmission is becoming increasingly urgent. As an important information dissemination tool, LED traffic displays are gradually becoming a key component of traffic management systems. Transportation systems require displays to be able to quickly respond to changes in road conditions, such as traffic accidents, road construction, and traffic control, and to promptly transmit this information to drivers and passengers.

[0003] Currently, the China Patent Network discloses an LED traffic guidance display screen for road traffic islands [Authorization Announcement No.: CN216817730U], which includes a support column, a shell fixedly connected to the top of the support column, four fixing plates fixedly connected inside the shell, a display screen body on one side of each of the four fixing plates, a rubber ring on one side of the display screen body, a fixing ring on one side of the rubber ring, a fixing hole on one side of the fixing ring, a screw inside the fixing hole, a support mesh inside the support column, a fan on the top of the support mesh, a solar panel on the top of the support mesh cylinder, and a battery box inside the shell.

[0004] The aforementioned LED traffic guidance display screen has the following drawbacks: the solar panel and the display screen are separate structures, requiring them to be installed sequentially on the support column during assembly, which makes assembly inconvenient. Furthermore, they are transported as two separate parts, making transportation inconvenient. Utility Model Content

[0005] The purpose of this utility model is to address the aforementioned problems in existing technologies by proposing an LED traffic display screen. The technical problem to be solved by this utility model is: how to solve the problem of inconvenient assembly and transportation caused by the external solar panel of existing LED traffic display screens.

[0006] The objective of this utility model can be achieved through the following technical solutions:

[0007] An LED traffic display screen includes a rectangular housing with a rectangular mounting cavity inside. The housing is a transparent plastic shell. The left, right, and top walls of the mounting cavity each have elongated mounting slots, each containing a solar panel. A rectangular enclosure is embedded within the mounting cavity, its outer wall fitting flush with the inner wall. The enclosure's top, left, and rear sides each have strip-shaped protrusions, each protrusion embedding a corresponding mounting slot and pressing against a corresponding solar panel. The mounting cavity houses a controller, a lithium battery module, and an LED circuit board. The controller and lithium battery module are located behind the LED circuit board. The front of the LED circuit board has a matrix of LEDs. The lithium battery module, LED circuit board, and all solar panels are electrically connected to the controller. A transparent front cover is sealed to the front of the housing.

[0008] Solar panels are installed on the left, right, and top sides of the internal casing of this structure, integrating solar panels into the traffic display screen. When the LED traffic display screen is installed on the roadside or on a gantry, the transparent casing allows sunlight to pass through and shine onto the solar panels. By placing solar panels in three different locations inside the casing, this structure maximizes the amount of sunlight the traffic display screen receives, ensuring timely charging of the lithium battery module and guaranteeing sufficient power. With the solar panels integrated inside the traffic display screen, there is no need to install additional solar panels on the bracket or column, simplifying the installation and transportation of the traffic display screen. The fence uses protruding strips on the outer surface to press and position the solar panels, ensuring their stable installation within the casing. When sunlight shines on the solar panels, the solar panels convert light energy into electrical energy and store it in the lithium battery module. The lithium battery module powers the LED circuit board, controller, and LED lights. The controller controls all LED lights to display warning information, while the transparent front cover allows drivers or pedestrians to easily observe the warning information displayed by the LED lights.

[0009] In the aforementioned LED traffic display screen, wiring notches are provided on the upper, left, and rear sides of the enclosure. Each solar panel is connected to the controller via a wire, which passes through the wiring notch. The wiring notch facilitates the wires connecting the solar panels to pass through the notch and connect to the controller.

[0010] In the aforementioned LED traffic display screen, a battery receiving slot and a controller receiving slot are provided on the bottom surface of the mounting cavity. The lithium battery module is housed in the battery receiving slot, and the controller is housed in the controller receiving slot. The two receiving slots facilitate the placement of the controller and the lithium battery module.

[0011] In the aforementioned LED traffic display screen, several support columns are distributed on the bottom surface of the mounting cavity. Each support column has a screw on its outer end face. All support columns are arranged in a rectangular pattern. Several through holes are formed on the LED circuit board, each corresponding to a support column. The screw on each support column passes through the corresponding through hole, and a locking nut is screwed to the outer end of each screw. In this structure, the upper end of the support column abuts against the back of the LED circuit board, thus providing support. The insertion of the support column into the through hole achieves pre-positioning of the LED circuit board. Tightening the locking nut onto the screw secures and positions the LED circuit board.

[0012] In the aforementioned LED traffic display screen, a reflective film is affixed to the front of the front cover. The reflective film has a window in the center, and the LED circuit board has an LED light distribution area. All LEDs are located within this area, and the window coincides with the LED light distribution area. By affixing a ring of reflective film to the transparent front cover, the film serves two purposes: firstly, it reflects light, providing a warning effect; secondly, it obscures the locking nut, making it difficult for outsiders to observe, thus enhancing the overall aesthetics of the traffic display screen. The area of ​​the window is roughly equivalent to the area of ​​the LED light distribution area, allowing for easy and direct observation of the warning information displayed by the LEDs.

[0013] In the aforementioned LED traffic display screen, the front cover includes a sealing part extending into the mounting cavity and fitting against the inner wall of the enclosure. The sealing part is connected to the inner wall of the enclosure via waterproof adhesive. The outer wall of the sealing part has a pressure plate that abuts against the front face of the housing and the front face of the enclosure. The pressure plate is rectangular and is connected to both the front face of the housing and the front face of the enclosure via waterproof adhesive. The sealing part and the inner wall of the enclosure are connected via waterproof adhesive to form a first seal, and the pressure plate and the front face of the housing and the front face of the enclosure are connected via waterproof adhesive to form a second seal, giving the LED traffic display screen a good overall waterproof effect. Furthermore, the sealing part is inserted into the enclosure and fits tightly against it, clamping the enclosure with the housing to achieve stable positioning of the enclosure.

[0014] Compared with the prior art, the LED traffic display screen of this utility model has the following advantages: This structure allows the traffic display screen to receive sunlight to the maximum extent by setting solar panels in three different positions inside the shell, so as to charge the lithium battery module in time and ensure sufficient power. After the solar panels are integrated inside the traffic display screen, there is no need to install additional solar panels on the bracket or column, which facilitates the installation of the traffic display screen and also facilitates transportation; The fence presses and positions the solar panels by the protrusions on the outer surface, so that the solar panels are stably installed in the shell.

A rectangular enclosure 5 is embedded in the mounting cavity 2. The outer side wall of the enclosure 5 fits against the inner wall of the mounting cavity 2. The upper, left, and rear sides of the enclosure 5 are provided with strip-shaped protrusions 50. Each protrusion 50 is embedded in a corresponding mounting groove 3 and presses against the corresponding solar panel 4. A controller 6, a lithium battery module 7, and an LED circuit board 8 are provided in the mounting cavity 2. The controller and the lithium battery module are located behind the LED circuit board 8. The front of the LED circuit board 8 has several LED lights 80 arranged in a matrix. The lithium battery module 7, the LED circuit board 8, and all the solar panels 4 are electrically connected to the controller 6. A transparent front cover plate 9 is sealed to the front end of the housing 1. Solar panels 4 are installed on the left, right, and top sides inside the housing 1 of this structure, thus integrating the solar panels 4 inside the traffic display screen. When the LED traffic display screen is installed on the roadside or on a gantry, the transparent housing 1 allows sunlight to pass through and shine onto the solar panels 4. By placing solar panels 4 at three different locations inside the housing 1, this structure maximizes the amount of sunlight received by the traffic display screen, enabling timely charging of the lithium battery module 7 and ensuring sufficient power. With the solar panels 4 integrated inside the traffic display screen, there is no need to install additional solar panels on the bracket or column. The solar panel 4 facilitates the installation and transportation of the traffic display screen. The enclosure 5 uses the protruding strips 50 on its outer surface to press and position the solar panel 4, ensuring that the solar panel 4 is stably installed inside the housing 1. When sunlight shines on the solar panel 4, the solar panel 4 converts light energy into electrical energy and stores it in the lithium battery module 7. The lithium battery module 7 powers the LED circuit board 8, the controller 6, and the LED lights 80. The controller 6 controls all the LED lights 80 to display warning information, while the transparent front cover 9 allows drivers or pedestrians to easily observe the warning information displayed by the LED lights 80.

[0025] like Figure 4 and Figure 5 As shown, wiring notches 51 are provided on the upper, left, and rear sides of the enclosure 5. Each solar panel 4 is connected to the controller 6 via a wire 10, which passes through the wiring notch 51. The wiring notch 51 facilitates the wires connecting the solar panel 4 to pass through the notch and connect to the controller 6. A battery receiving slot 20 and a controller receiving slot 21 are provided on the bottom surface of the mounting cavity 2. The lithium battery module 7 is placed in the battery receiving slot 20, and the controller 6 is placed in the controller receiving slot 21.

[0026] like Figure 3 , Figure 4 and Figure 6 As shown, several support pillars 22 are distributed on the bottom surface of the mounting cavity 2. Each support pillar 22 has a screw 23 on its outer end face. All support pillars 22 are rectangularly distributed. Several through holes are opened on the LED circuit board 8, and each through hole corresponds to a support pillar 22. The screw 23 on each support pillar 22 passes through the corresponding through hole, and a locking nut 11 is screwed to the outer end of each screw 23. The upper end of the support pillar 22 abuts against the back of the LED circuit board 8, thereby supporting the LED circuit board 8. The structure of the support pillar 22 inserted into the through hole realizes the pre-positioning of the LED circuit board 8. After the locking nut 11 is tightened on the screw 23, the LED circuit board 8 is pressed and positioned.

[0027] like Figure 1 , Figure 2 and Figure 3 As shown, a reflective film 12 is affixed to the front of the front cover plate 9. The reflective film 12 has a window 120 in the center. The LED circuit board 8 has an LED light distribution area 83, and all LED lights 80 are located within this area. The window 120 overlaps with the LED light distribution area 83. By affixing a ring of reflective film 12 to the transparent front cover plate 9, the reflective film 12 serves two purposes: firstly, it reflects light, providing a warning effect; secondly, it obscures the locking nut 11, making it difficult for outsiders to observe, thus enhancing the overall aesthetics of the traffic display screen. The area of ​​the window 120 is roughly equivalent to the area of ​​the LED light distribution area 80, allowing for easy and direct observation of the warning information displayed by the LED lights 80.

[0028] like Figure 3 and Figure 7 As shown, the front cover plate 9 includes a sealing part 90 that extends into the mounting cavity 2 and fits against the inner wall of the light-blocking baffle 5. The sealing part 90 is connected to the inner wall of the baffle 5 by a waterproof adhesive.
