[0002] An active light-emitting traffic sign, also known as an LED light-emitting traffic sign, can utilize solar or wind power, or be connected to mains power via a transformer. It uses LED light sources and retroreflective materials to make the surface, and the sign's own light source can meet the requirements for sign information recognition under all weather conditions.

[0003] The LED light source structure of these traffic signs is located inside the sign. During use, the sign inevitably malfunctions, requiring maintenance of the internal LED light source structure. This necessitates opening the outer layer of the sign to expose the LED light source for inspection. The outer layer is typically connected to the sign body by multiple bolts distributed around the perimeter. Maintenance involves disassembling and reassembling these bolts, resulting in significant time spent on them and reducing the efficiency of LED light source maintenance. Utility Model Content

[0004] The purpose of this utility model is to at least solve one of the technical problems existing in the prior art, and to provide a traffic sign that can actively emit light, which has the function of connecting the outer layer of the sign to the sign body without bolts, so that when inspecting the internal LED light source structure of the sign, time is not spent on the disassembly and assembly of bolts, thereby improving the maintenance efficiency of the LED light source of the sign.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an active light-emitting traffic sign, including a support rod, with the upper end of the support rod fixedly connected to the sign body, and an installation groove provided on the left side of the sign body;

[0006] An LED light source module is installed inside the mounting slot, and the LED light source module is installed on the right wall of the mounting slot;

The use of terms like "first" and "second" is merely for distinguishing technical features and should not be construed as indicating or implying relative importance, or implicitly indicating the quantity or sequence of the indicated technical features.

[0030] In the description of this utility model, unless otherwise explicitly defined, terms such as "setting," "installation," and "connection" should be interpreted broadly, and those skilled in the art can reasonably determine the specific meaning of the above terms in this utility model in conjunction with the specific content of the technical solution.

[0031] Please see Figure 1-4 This utility model provides a new technical solution: an actively luminous traffic sign, including a support rod 1, with a sign body 2 fixedly connected to the upper end of the support rod 1. A mounting groove 3 is provided on the left side of the sign body 2, and an LED light source module 4 is installed inside the mounting groove 3. The LED light source module 4 is mounted on the right wall of the mounting groove 3. A cable groove 5 is provided on the bottom wall of the mounting groove 3, with the lower side of the cable groove 5 passing through the sign body 2 and the support rod 1. A cable 6 is electrically connected to the lower side of the LED light source module 4, extending into the interior of the cable groove 5. A sign body movably fits on the outer surface of the sign body 2. The outer layer 7 of the signboard has a display panel 8 fixedly connected to its left side. The display panel 8 passes through the outer layer 7 of the signboard and is compatible with the LED light source module 4. The signboard body 2 and the outer layer 7 of the signboard are provided with two snap-fit ​​mechanisms. The support rod 1 and the outer layer 7 of the signboard can be connected together through the two snap-fit ​​mechanisms. The connection structure of the two snap-fit ​​mechanisms is the same and is arranged symmetrically front and back. The following description focuses on the front snap-fit ​​mechanism. The snap-fit ​​mechanism includes a fixed slot 9, a sliding slot 10, two limiting sliding slots 11, a sliding block 12, two limiting sliders 13, a snap-fit ​​block 14, and a spring 15.

[0032] Furthermore, a fixed slot 9 is formed on the front wall of the outer layer 7 of the sign, a sliding groove 10 is formed on the lower side of the sign body 2, two limiting sliding grooves 11 are formed on the left and right walls of the sliding groove 10 respectively, a sliding block 12 is slidably connected to the inside of the sliding groove 10, the lower side of the sliding block 12 extends out of the sign body 2, two limiting sliders 13 are fixedly connected to the left and right sides of the sliding block 12 respectively, the two limiting sliders 13 are slidably connected to the inside of the two limiting sliding grooves 11 respectively, a snap-fit ​​block 14 is fixedly connected to the front side of the sliding block 12, the snap-fit ​​block 14 is adapted to the fixed slot 9, a spring 15 is fixedly connected to the rear side of the sliding block 12, and the rear end of the spring 15 is fixedly connected to the sliding groove 10 and the support rod 1.

[0033] Furthermore, during operation, city power is transmitted to the LED light source module 4 via cable 6, causing the LED light source module 4 to emit light. The light emitted by the LED light source module 4 is transmitted through the display panel 8, which is a semi-transparent panel. This allows light to pass through the strokes of the text and the outlines of the graphics in the sign, thus forming the pattern of the traffic sign. When the LED light source module 4 malfunctions and needs repair, the operator pushes the front sliding block 12 backward. The front sliding block 12 then moves the front locking block 14 synchronously, causing the front locking block 14 to move out of the front fixed slot 9. At this time, the locking state between the locking block 14 and the fixed slot 9 is released, and the sliding block 12 is inside the sliding groove 10. When sliding, the two limiting sliders 13 will slide synchronously. The two limiting sliders 13 slide inside the two limiting grooves 11 respectively, thereby limiting the sliding block 12. At this time, the front spring 15 begins to compress and pushes the rear sliding block 12 forward. As mentioned above, the matching snap-fit ​​state between the rear snap-fit ​​block 14 and the rear fixing groove 9 will also be released. Then, by moving upward, the outer layer 7 and the display panel 8 of the sign can be removed, and the LED light source module 4 will be exposed. Then, the staff can perform maintenance on the LED light source module 4. After the maintenance is completed, the outer layer 7 and the display panel 8 of the sign can be reinstalled on the sign body 2 in the above manner.

[0034] Furthermore, in this way, the outer layer 7 of the sign can be connected to the support rod 1 without bolts, so that when the LED light source module 4 inside the sign is inspected, no time is spent on the installation and removal of bolts, thereby improving the maintenance efficiency of the LED light source module 4.

[0035] Structural Description: Support rod 1: Its main function is to stably support the traffic sign, ensuring that it can be displayed stably above the road for a long time, providing clear and unambiguous directional information for road users;

[0036] The sign body 2, mounting slot 3, and LED light source module 4 are fixedly connected to the upper end of the support rod 1. The mounting slot 3 is opened on the left side of the sign body 2. The LED light source module 4 is installed inside the mounting slot 3. Thus, the sign body 2 and the mounting slot 3 play the role of installing and fixing the LED light source module 4, so that the LED light source module 4 can be fixed inside the sign. The LED light source module 4 is the core component of the luminous traffic sign, responsible for actively emitting light at night or under poor visibility conditions, providing clear traffic information.

[0037] Cable trough 5 and cable 6: Cable trough 5 is opened on the bottom wall of mounting groove 3. The lower side of cable trough 5 passes through sign body 2 and support rod 1. Cable 6 is electrically connected to the lower side of LED light source module 4. Cable 6 extends into the interior of cable trough 5 and then extends underground after passing through cable trough 5, and then connects to the city's power system. Thus, LED light source module 4 can light up by the city's power. At the same time, it avoids the cable 6 being exposed on the outside, thus avoiding the impact of external factors on cable 6 and improving the service life of cable 6.

[0038] The outer layer 7 of the sign and the display panel 8: The outer layer 7 of the sign is movably fitted on the outer surface of the sign body 2, so that the outer layer 7 can protect the LED light source module 4 and prevent external factors from affecting the LED light source module 4. The display panel 8 is compatible with the LED light source module 4. The display panel 8 is a semi-transparent panel, so that the strokes of the text and the outline of the graphics of the sign can transmit light. So that the light of the LED light source module 4 can form the pattern of the traffic sign after passing through the display panel 8.

[0039] Fixed slot 9: There are two fixed slots 9. The two fixed slots 9 are respectively opened on the front wall and the rear wall of the outer layer 7 of the sign. The fixed slots 9 are adapted to the snap-fit ​​block 14 to form a snap-fit ​​fixation, so that the sign body 2 and the sign outer layer 7 can be connected together, and the sign outer layer 7 is prevented from falling off the sign body 2 due to external factors.

[0040] Sliding groove 10 and limiting groove 11: There are two sliding grooves 10, both of which are opened on the lower side of the sign body 2. The two sliding grooves 10 are respectively set on the front and rear sides of the support rod 1. There are four limiting grooves 11, which are respectively opened on the left and right walls of the two sliding grooves 10.

[0041] Sliding block 12 and limiting slider 13: There are two sliding blocks 12, which are slidably connected to the inside of two sliding grooves 10 respectively. The lower side of each sliding block 12 extends out of the sliding groove 10. There are four limiting sliders 13, which are fixedly connected to the left and right sides of the two sliding blocks 12 respectively. The four limiting sliders 13 are slidably connected to the inside of four limiting sliding grooves 11 respectively. Thus, the limiting sliders 13 can limit the sliding blocks 12, so that the sliding blocks 12 can only slide back and forth, avoiding the sliding blocks 12 from moving up and down, which would cause the locking mechanism to fail to lock properly.

[0042] Snap-fit ​​block 14: There are two snap-fit ​​blocks 14. The two snap-fit ​​blocks 14 are fixedly connected to the two sliding blocks 12 on the opposite sides. The two snap-fit ​​blocks 14 are adapted to the two fixed slots 9. After the snap-fit ​​blocks 14 slide into the inside of the fixed slots 9, the snap-fit ​​mechanism can be completed. At this time, the outer layer 7 of the sign can be connected to the sign body 2. When the snap-fit ​​blocks 14 and the fixed slots 9 are released, the outer layer 7 of the sign can be easily and quickly removed from the sign body 2.

[0043] Spring 15: There are two springs 15. The two springs 15 are fixedly connected to the opposite surfaces of the two sliding blocks 12 respectively. The opposite ends of the two springs 15 are fixedly connected to the two sliding grooves 10 and the support rod 1 respectively. When the springs 15 are relaxed, the locking block 14 is locked inside the fixed locking groove 9.

[0044] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model 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 utility model.
