[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] Reference Figures 1-5 This utility model provides a variable information display device for highways, which aims to solve the problems of inconvenient transportation and installation of the overall structure of highway information display devices in the prior art, as well as the cumbersome replacement and maintenance of the display screen after damage.

[0028] Specifically, the device includes an assembly component 1 and a display component 3 mounted on the assembly component 1. The assembly component 1 serves as the installation and support platform for the entire device, providing a stable structural support for the display component 3. The display component 3 is used to carry and display variable traffic information. The assembly component 1 includes a base 102 as the foundation and a connecting column 101 vertically fixed to the base 102. The assembly component 1 also includes a bottom plate 104 and a top plate 105. Both the bottom plate 104 and the top plate 105 are slidably fitted onto the outer wall of the connecting column 101. In the installed state, the display component 3 is clamped and fixed between the bottom plate 104 and the top plate 105. Through this modular structural combination, convenient transportation and rapid on-site assembly of the device are achieved.

[0029] Display assembly 3 includes a frame 301 for housing a display screen 302. A fixing frame 304 is fixedly connected inside the frame 301. The display screen 302 is detachably installed inside the fixing frame 304. A key structure for quick assembly and disassembly of the display screen is located on the side wall of the display screen 302. A locking block 303 is fixedly connected to the side wall of the display screen 302. A hollow column 305 is opened inside the locking block 303. A locking ball 307 is slidably disposed inside the hollow column 305. A spring 306 is elastically connected between the locking ball 307 and the bottom wall of the hollow column 305. In the assembled state, the spring 306... 06 continuously applies an outward elastic force to the locking ball 307, allowing part of the spherical surface of the locking ball 307 to extend out of the locking block 303 under the elastic force of the spring 306 and engage with the fixing frame 304. This self-locking structure using a spring-driven locking ball allows the display screen 302 to automatically lock when pushed into the designated position of the fixing frame 304. When disassembly is required, simply overcome the elastic force of the spring 306 to pull the display screen 302 outward, which will cause the locking ball 307 to retract, thus allowing the display screen 302 to be easily removed. The entire process does not require the use of any special tools, improving maintenance efficiency.

[0030] To enhance the overall structural stability and load-bearing capacity, the assembly component 1 also includes a limiting post 106 and a fixing block 103. The limiting post 106 and the connecting post 101 are fixedly connected to the base 102 in parallel, thus forming a multi-point support frame foundation. The fixing block 103 is firmly fixed to the bottom of the limiting post 106, providing a precise and reliable support benchmark for the base plate 104. During installation, the lower surface of the base plate 104 directly overlaps the upper surface of the fixing block 103, ensuring the height and level of the base plate 104, which guarantees the stable placement of the subsequent display component 3. Through the cooperation of the limiting post 106 and the fixing block 103, the accidental slippage of the base plate 104 is effectively prevented, and the weight of the entire display device is shared, improving the device's wind and vibration resistance in outdoor environments.

[0031] To ensure that the base plate 104 and top plate 105 can slide smoothly and be precisely positioned on the connecting column 101 and the limiting column 106, both the base plate 104 and the top plate 105 are provided with through holes for the connecting column 101 and the limiting column 106 to pass through. The diameter of these through holes is precisely matched with the outer diameter of the connecting column 101 and the limiting column 106, which not only ensures the smoothness of sliding, but also reduces the shaking gap after installation, making the frame connection of the entire assembly component 1 tighter and more secure.

[0032] The frame 301 of the display component 3 is an integral box structure used to protect the internal components from the influence of the external environment. The fixed frame 304 is fixedly connected inside the frame 301 as a standardized mounting component, providing a unified installation interface for the display screen 302. The display screen 302 can be detachably installed inside the fixed frame 304, so that different batches or models of display screens 302 can be interchanged as long as they meet the interface standard, which enhances the flexibility and maintainability of the system.

[0033] To ensure reliable locking of the ball 307, a locking groove is specially provided on the inner wall of the fixing frame 304 at a position corresponding to the ball 307. When the display screen 302 is pushed into place, the ball 307 is pushed into the locking groove by the spring 306, forming a clear physical lock. This cooperation between the groove and the ball not only provides clear tactile and audible feedback to inform the operator that the installation is in place, but also enhances the vibration and impact resistance of the connection, preventing the display screen 302 from loosening or falling off due to vibrations caused by road vehicles.

[0034] To ensure smooth and stable insertion and removal of the display screen 302 and prevent scratches or jamming, the inner wall of the fixing frame 304 is integrally formed or fixedly connected with a slide rail for the display screen 302 to slide. At the same time, the side wall of the display screen 302 has a structure adapted to the slide rail, such as a slider or a groove. During installation, the slider or groove of the display screen 302 is aligned with the slide rail of the fixing frame 304 and pushed in. The slide rail precisely guides the movement trajectory of the display screen 302, ensuring that the display screen 302 always moves smoothly along a straight path, avoiding installation difficulties or damage to the internal precision structure caused by tilting or shaking.

[0035] A center pin is provided inside the hollow column 305 of the locking block 303. The spring 306 is specifically a helical spring, and the spring 306 surrounds the outer periphery of the center pin inside the hollow column 305. The two ends of the spring 306 abut against the inner side of the locking ball 307 and the root of the center pin, respectively. The presence of the center pin provides radial support for the spring 306, effectively preventing the spring 306 from bending, eccentric or buckling failure during long-term compression and rebound. This ensures that the spring 306 can continuously and stably provide positive ejection pressure to the locking ball 307, thereby ensuring the long-term reliability of the quick disassembly mechanism.

[0036] It also includes an electrical box 2, which is fixedly installed on the side wall of the base 102. The electrical box 2 integrates core electrical components such as a power module and a control circuit board, which are used to receive instructions from the control center and drive the display screen 302 to display the corresponding information. Placing the electrical box 2 on the side wall of the base 102 facilitates daily maintenance and wiring operations, and also keeps it away from road dust and water accumulation, thus improving the safety and reliability of the electrical system.

[0037] Working principle: When using the highway variable information display device, the first assembly component 1 is designed in a modular way, which can facilitate faster and more convenient transportation, as well as reverse transportation. Then, the electrical box 2 can be used to control the power supply, etc. The inner wall of the assembly component 1 is equipped with the display component 3, which is used for quick disassembly and can replace the damaged display screen 302.

[0038] Next, when assembling component 1 in a modular fashion, the outer wall of the connecting column 101 can first be inserted into the interior of the base 102. Then, during the assembly, the interior of the base plate 104 slides against the outer wall of the connecting column 101, and at the same time, the interior of the base plate 104 slides to the outer wall of the limiting column 106. The bottom of the limiting column 106 is fixed with a fixing block 103, and the top of the fixing block 103 will block the bottom of the base plate 104. After the base plate 104 is installed, the side wall of the display component 3 is placed on the inner wall of the base plate 104. After the display component 3 is installed, the bottom of the top plate 105 slides against the outer wall of the connecting column 101, and the bottom of the top plate 105 is placed on the top of the display component 3, thus achieving the effect of modular assembly.

[0039] Next, after the display screen 302 is damaged, it is necessary to pull the display screen 302 first. At the same time, the side wall of the display screen 302 slides inside the fixed frame 304, and the fixed frame 304 can limit the display screen 302. The side wall of the fixed frame 304 is fixed inside the frame 301. After the display screen 302 is separated from the fixed frame 304, it will drive the side wall's locking block 303 to slide inside the frame 301. Then, during the process of the locking block 303 being moved under force, it will squeeze the side wall's locking ball 307, causing it to slide on the inner wall of the hollow column 305. Then, during the process of the locking ball 307 being under force, it will compress the outer wall's spring 306, achieving the effect of quickly disassembling the display screen 302.
