Technical Field
[0001] The invention relates to the technical field of traffic signs, and in particular to a waterproof traffic light box sign. Background Art
[0002] Existing traffic light box signs have many problems in actual use, the most prominent of which is the waterproof problem. The aluminum back plate and aluminum frame of the existing light box are usually made of hard materials, which are easy to get into water, dust and light leakage, causing damage to the internal structure of the light box. In addition, light leakage may cause traffic visual misjudgment and affect traffic safety.
[0003] At present, the light box frames on the market usually do not have waterproof strips at the left and right slots, which makes it easy for water to enter. If the existing light box frame is designed to be thicker, it can be fixed by tightening the self-tapping screws, but the increase in thickness will lead to increased costs. If the light box frame is designed to be thinner, the self-tapping screws cannot be tightened firmly, which will make the installation of the light box and the bracket unstable.
[0004] At the same time, the control system of the existing light box is not accurate in the switching time between day and night. This is mainly due to the inconsistent dark time period throughout the year, which makes it impossible for the light box to be accurately controlled according to the light changes. Existing traffic light box signs usually use PC boards. Since traffic light box signs are mostly installed outdoors, PC boards are prone to deformation and yellowing in high temperatures in summer, affecting the service life and effect of the light box.
[0005] Therefore, a new light box structure design is urgently needed to solve the waterproof problem first, and also solve the problems of dustproof, high temperature resistance and reliable fixation, to ensure that the light box can work normally in various environments and extend its service life. The new design should improve the use effect and safety of the light box sign, and ensure the reliability and stability of the traffic light box sign under adverse weather conditions. Summary of the invention
[0006] The invention relates to a waterproof traffic light box sign, aiming to provide a traffic light box sign structure that is effectively waterproof and dustproof, and solves the problems that the existing light box is easily infiltrated with water and dust in outdoor environments, causing damage to the internal structure of the light box and light leakage.
[0007] The waterproof traffic light box sign of the present invention comprises light box frames arranged opposite to each other, light box boards arranged between the light box frames, the light box frames are provided with wedge-shaped receiving grooves, the ends of the light box boards are covered in sealing strips, the sealing strips are arranged in the receiving grooves, and the sealing strips are shaped by the receiving grooves to have a wedge-shaped cross section. Through this design, an effective sealing connection is achieved between the light box boards and the light box frames, preventing water and dust from entering the interior of the light box.
[0008] The light box frame and the light box board are sealed and connected by the cooperation of the storage groove and the sealing strip, and the end of the light box board is embedded in the storage groove to form a stable connection structure. The light box board includes an aluminum back plate, an LED light board and a high temperature resistant sunlight board, the aluminum back plate and the high temperature resistant sunlight board are arranged oppositely, the LED light board is arranged between the aluminum back plate and the high temperature resistant sunlight board, and the edges of the aluminum back plate and the high temperature resistant sunlight board are embedded in the storage groove of the light box frame through the sealing strip to form an overall sealed structure.
[0009] The light box frame includes left and right limit ribs, left and right waterproof rubber strip slots and frame connectors, the left and right limit ribs and waterproof rubber strip slots form a wedge-shaped storage slot, and the frame connectors are used to fix the light box board and enhance the structural stability. The sealing strip is made of highly elastic rubber material, has good waterproof and sealing properties, prevents water and dust from entering the interior of the light box, and enhances the service life and protection performance of the light box.
[0010] In addition, the present invention also includes a light controller installed on the aluminum back panel, which integrates a light-controlled switch and a constant-on / flashing switch key.

[0030] The invention relates to a waterproof traffic light box sign, aiming to provide a traffic light box sign structure that is effectively waterproof and dustproof, and solves the problems that the existing light box is easily infiltrated with water and dust in outdoor environments, causing damage to the internal structure of the light box and light leakage.
[0031] Reference Figure 1 and Figure 2 The schematic diagram of the exploded view of the traffic light box sign is shown. The traffic light box sign includes light box frames 1 arranged relatively to each other, and light box boards 13 arranged between the light box frames 1. The light box frame 1 is provided with a wedge-shaped storage groove 10, and the end of the light box board 13 is covered in a waterproof rubber strip 7, which is arranged in the storage groove 10, and the waterproof rubber strip 7 is molded by the storage groove 10 to have a wedge-shaped cross-section. Through this design, an effective sealing connection is achieved between the light box board and the light box frame 1 to prevent water and dust from entering the interior of the light box. The light box frame 1 and the light box board 13 are sealed by the cooperation of the storage groove 10 and the waterproof rubber strip 7, and the end of the light box board is embedded in the storage groove 10 to form a stable connection structure.
[0032] Reference Figure 5 , showing the structure of the light box frame 1 of the waterproof traffic light box sign. The light box frame 1 includes left and right limit ribs 9, left and right waterproof rubber strip slots 14 and frame connectors 8. The limit ribs 9 are located on both sides of the interior of the light box frame 1, and are used to fix the position of the light box board to ensure that it is firmly positioned in the frame without displacement. The top of the limit rib 9 has an inward extending portion, which can clamp the edge of the light box board during installation to prevent it from moving up and down.
[0033] The waterproof rubber strip slot 14 is located outside the limiting rib 9, and the two form a wedge-shaped receiving slot 10 for embedding the waterproof rubber strip 7 to achieve a waterproof sealing effect. The design of the waterproof rubber strip slot 14 allows the waterproof rubber strip 7 to be tightly fixed in the slot 14. The waterproof rubber strip 7 is soft and elastic, can adapt well to the shape of the slot 10, and form an effective seal when squeezed.
[0034] In actual application, the end of the light box board 13 is covered in the waterproof rubber strip 7. During installation, the waterproof rubber strip 7 is first put on the edge of the light box board 13, and then the light box board is inserted into the light box frame 1, and is pressed into the waterproof rubber strip slot 10 together with the waterproof rubber strip 7, and is tightly fixed by the wedge structure. The waterproof rubber strip 7 has a wedge-shaped cross-section, and the compression amount at the bottom is greater than the compression amount at the top, and the seal is tighter. This design effectively prevents external water and dust from entering the interior of the light box, protects the internal LED light board 3 and other components, and improves the durability and service life of the light box. Through the structure of the limiting ribs 9 and the waterproof rubber strip slot 14, the light box board is fixed and sealed, and the overall stability and waterproof performance of the light box are enhanced.
[0035] The wedge-shaped structural seal has many benefits. First, the wedge-shaped deformation and pressure distribution ensure that the bottom pressure of the wedge-shaped structure is concentrated, ensuring the tight connection between the light box board and the light box frame 1, which can effectively prevent water and dust from entering the interior of the light box and enhance the structural stability. Second, the wedge-shaped design simplifies the installation process and realizes the fixation of the light box board. Its gradually decreasing cross-sectional dimensions can automatically adapt to dimensional tolerances, reducing manual operation errors and installation costs. Third, the evenly distributed pressure makes the waterproof strip 7 not easy to deform and age during long-term use, and it can still maintain a reliable seal even in harsh environments. Fourth, the wedge-shaped structure of the waterproof strip 7 hidden inside the light box frame 1 does not affect the appearance of the light box, maintaining a beautiful integrated design.
[0036] Continue to refer to Figure 2, the figure shows a schematic diagram of the internal structure of a waterproof traffic light box sign. The light box frame 1 provides physical support and outline for the entire light box. The aluminum back plate 2 is installed on the top of the light box frame 1, and is connected to the light box frame 1 through a storage slot 10 and a waterproof adhesive strip 7, which plays a role in closing and supporting the internal structure. The LED light board 3 is installed in the middle of the light box frame 1, located between the aluminum back plate 2 and the high temperature resistant sunlight board 5, providing the main light source for the light box sign. The light control controller 4 is installed on the top of the aluminum back plate 2, and senses the light intensity of the surrounding environment through the light control switch 11 to control the switch and working mode of the LED light board 3. The high temperature resistant sunlight board 5 is installed at the bottom of the light box frame 1, and is connected to the light box frame 1 through a waterproof adhesive strip 7 and a storage slot 10, which plays a role in protection and light transmission. The reflective film 6 is attached to the bottom of the high temperature resistant sunlight board 5 to reflect light and improve the visibility of the traffic sign. The waterproof rubber strip 7 is embedded in the wedge-shaped receiving groove 10 of the light box frame 1, covers the end of the light box board, and achieves sealing through the wedge-shaped structure to prevent water and dust from entering the interior of the light box.
[0037] Further, refer to Figure 3 It is a schematic diagram of the layering of the signboard according to the embodiment of the present invention, which shows in detail the relative positions of the aluminum back plate 2, the LED light board 3 and the high temperature resistant sunlight board 5. The light box board includes the aluminum back plate 2, the LED light board 3 and the high temperature resistant sunlight board 5, the aluminum back plate 2 and the high temperature resistant sunlight board 5 are arranged relatively, the LED light board 3 is arranged between the aluminum back plate 2 and the high temperature resistant sunlight board 5, and the edges of the aluminum back plate 2 and the high temperature resistant sunlight board 5 are embedded in the storage groove 10 of the light box frame 1 through the waterproof adhesive strip 7 to form an overall sealing structure.
[0038] Furthermore, the bottom layer is the aluminum back plate 2, which provides support and strength for the entire light box sign and ensures the stability of the light box structure. Immediately above the aluminum back plate 2 is the LED light board 3, which contains multiple LED particles and provides a light source, so that the sign has good visibility at night or in low light conditions. The high temperature resistant sunlight board 5 is installed above the LED light board 3 to form a protective layer with high temperature resistance to prevent deformation under high temperature conditions. The top layer is a reflective film 6, which covers the high temperature resistant sunlight board 5. The surface of the reflective film 6 is printed with traffic signs (such as "speed limit"), which improves the visibility of the sign by reflecting light, especially at night or in poor light conditions. This layered structure design, through the combination of the aluminum back plate 2, the LED light board 3, the high temperature resistant sunlight board 5 and the reflective film 6, not only provides a reliable light source and reflective effect, but also ensures the stability and durability of the light box sign under various environmental conditions.
[0039] Reference Figure 4, showing the structure of the light control controller 4 and its input and output configuration. The light control controller 4 has a 220V input terminal and a 24V output terminal. It senses the light intensity of the surrounding environment through the light control switch 11 and controls the switch state of the traffic light box sign. The light control controller 4 is installed on the aluminum back panel 2, and integrates the light control switch 11 and the constant light and flashing switch key 12. It senses the ambient light through the photoresistor. When the ambient light is insufficient, the light box sign is automatically turned on, and when the light is sufficient, the light box sign is turned off to save energy. The constant light and flashing switch key 12 is used to select the working mode of the light box. It can be set to the constant light mode or the flashing mode as needed to adapt to different traffic conditions and needs. The flashing frequency of the flashing mode is 30±5 times per minute, and the duty cycle is 1:1.5. This design not only improves the intelligence level of the traffic light box sign, but also effectively saves energy and extends the service life of the light box.
[0040] Through the above design, the present invention achieves good waterproof and dustproof effects of the waterproof traffic light box sign, ensures the stable operation of the light box under various adverse weather conditions, and improves the service life and safety of the traffic light box sign.
