Description

Technical Field

[0001] This utility model relates to the field of LED screen technology, and in particular to an LED screen with an adjustment function. Background Technology

[0002] In the field of highway traffic management, LED screens are key equipment for transmitting real-time road condition information, traffic control instructions and safety reminders. The effectiveness of their information display is directly related to driving safety and traffic efficiency. However, existing highway LED screens have many limitations in practical applications and are difficult to meet the current needs of special weather and complex traffic scenarios.

[0003] Most LED screens on highways are fixed-size, single-unit structures with a fixed and non-adjustable display area. Under normal weather conditions, these screens can generally meet information transmission needs. However, when traffic congestion or temporary traffic control is caused by severe weather, fixed-size LED screens struggle to simultaneously display multi-dimensional information. For example, in rainy weather with traffic restrictions at highway entrances, existing screens typically only alternate between displaying "entrance closed" warnings and detour route information. Frequent screen switching can cause gaps in drivers' information reception, making it difficult for them to accurately understand the control measures and detour plans in a short time. This can lead to hesitation, delayed deceleration, and other problems, exacerbating traffic congestion. Similarly, in complex road conditions such as icy bridges during snowfall, it is necessary to simultaneously convey multiple related information such as the location of icy sections, recommended speeds, and anti-skid warnings. Fixed-size screens cannot achieve parallel display of this information, resulting in incomplete and disjointed information transmission, affecting drivers' overall judgment of road conditions. Utility Model Content

[0004] The purpose of this invention is to solve the problem that existing technologies mostly use single-unit structures of fixed size, with a fixed and non-adjustable display area, and to propose an LED screen with an adjustable function.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: An adjustable LED screen includes a base plate, which is fixed to a high-speed mounting bracket by screws. A support base is fixed to the top of the base plate, and an LED screen one is disposed above the support base. An LED screen two is disposed on the back of the LED screen one. An adjustment mechanism for rotating the LED screen two is installed on the base plate. The adjustment mechanism includes mounting strips fixed to the top of the base plate, and a rotating rod is rotatably connected between the mounting strips via bearings. A rotating cylinder is fixed to the outer surface of the rotating rod.

[0006] Preferably, a fixing block is fixed to the outer surface of the rotating cylinder, and the fixing block is fixedly connected to the LED screen by bolts.

[0007] Preferably, the mounting strip is equipped with a drive unit for rotating the rotating rod, and the drive unit is a servo motor.

[0008] Preferably, the support base is provided with a quick-release mechanism, which includes an insertion hole opened on the top of the support base, and an insertion block fixed at the bottom of the LED screen. The insertion block is embedded in the insertion hole, and a locking hole is opened in the insertion block.

[0009] Preferably, the support base has an installation cavity, and a locking rod slides in the locking hole.

[0010] Preferably, a return spring is fixed to the inner wall of the mounting cavity, a pull block is fixed to the end of the return spring away from the support seat, and the locking rod is fixed to the end of the pull block away from the return spring.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows: 1. By adjusting the mechanism, the drive unit rotates the rotating rod between the mounting strips, causing the rotating cylinder to rotate accordingly. This, in turn, drives the LED screen two to flip through the fixing block and bolts, realizing the angle adjustment and unfolding / storage of the LED screen two. In special weather conditions, the LED screen two can be flipped to the same plane as the LED screen one, expanding the overall area of ​​the display screen and enabling the simultaneous display of more dimensions of information. This avoids information gaps caused by frequent screen switching and improves the efficiency and accuracy of information transmission in special weather conditions.

[0012] 2. The quick-release mechanism, with its interlocking holes, insert blocks, locking holes, mounting chambers, return springs, pull blocks, and locking rods, allows for rapid disassembly of the LED screen from its support base. Pulling the pull block compresses the locking rod, causing it to retract from the locking hole, thus removing the insert block. Conversely, releasing the pull block allows the return spring to push the pull block, inserting the locking rod into the locking hole, completing the rapid installation of the LED screen. This simplifies the maintenance and replacement process of the LED screen, saves manpower and time, and improves the equipment's emergency response capability. Attached Figure Description

[0017] Furthermore, a fixing block 55 is fixed to the outer surface of the rotating drum 54, and the fixing block 55 is fixedly connected to the LED screen 4 by bolts 56.

[0018] Furthermore, a drive unit 52 for rotating the rotating rod 53 is installed on the mounting strip 51. The drive unit 52 is a servo motor.

[0019] The base plate 1 is fixed to the high-speed mounting bracket with screws. During normal use, reminder information can be displayed through LED screen 3. In special weather conditions, such as snowy weather or icy bridge surfaces, the state of LED screen 4 needs to be adjusted. At this time, the drive unit 52 on the mounting strip 51 is activated. Its output shaft drives the rotating rod 53 to rotate between the mounting strips 51 through bearings. The rotation of the rotating rod 53 will drive the rotating cylinder 54 fixed on its outer surface to rotate together. The rotation of the rotating cylinder 54 will drive the LED screen 4 to rotate through the fixing block 55 fixed on the outer surface and the bolt 56 connected to the fixing block 55. By controlling the rotation direction and angle of the drive unit 52, the LED screen 4 can be unfolded and retracted. In special weather conditions, it can be flipped to the same plane as LED screen 3 to expand the display area. In normal weather conditions, it can be retracted to the back of LED screen 3 to reduce space occupation. The bolt 56 ensures its stability during flipping. The drive unit 52 is a servo motor with the model number MHMD042G1U.

[0020] The further advantages of adopting the above are: it enables the angle adjustment and unfolding and storage of LED screen 2 4; in special weather conditions, LED screen 2 4 can be flipped to the same plane as LED screen 1 3, which expands the overall area of ​​the display screen, can display more dimensions of information at the same time, avoids information gaps caused by frequent screen switching, and improves the efficiency and accuracy of information transmission in special weather conditions.

[0021] Based on Example 1, Example 2: Reference Figures 1-6 An adjustable LED screen includes a base plate 1, which is fixed to a high-speed mounting bracket by screws. A support base 2 is fixed to the top of the base plate 1, and an LED screen 3 is provided above the support base 2. An LED screen 4 is provided on the back of the LED screen 3.
