Technical Field

[0001] This utility model belongs to the field of highway warning technology, and in particular relates to a foldable and liftable vehicle-mounted LED display screen for highway warning. Background Technology

[0002] Highway warning displays are electronic devices installed on highways to provide real-time traffic information, warnings, and other important notices to passing drivers. They typically consist of LED displays that can show information through text, images, or symbols, improving traffic safety and flow.

[0003] Highway warning LED displays typically need to be installed within the driver's line of sight. However, the height of some existing warning signs is fixed and difficult to adjust, making it difficult for drivers of different vehicle types to see all the warning information on the display. This can easily lead to traffic congestion and accidents caused by emergencies or road construction. Therefore, we propose a foldable and liftable vehicle-mounted LED display for highway warnings. Utility Model Content

[0004] The purpose of this utility model is to provide a foldable and liftable vehicle-mounted LED display screen for highway warnings. By rotating the first knob, the LED display screen can be moved, thereby changing the height of the LED display screen. This solves the problem that drivers of different vehicle models cannot see all the warning information on the display screen, which can easily cause traffic congestion and accidents due to emergencies or road construction.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0006] This utility model is a foldable and liftable vehicle-mounted LED display screen for highway warning, including a mounting frame, a height adjustment mechanism on the mounting frame, and a folding mechanism below the height adjustment mechanism;

[0007] The height adjustment mechanism includes a first threaded rod, which is rotatably connected inside the mounting bracket. The top end of the first threaded rod passes through the top of the mounting bracket and extends therefrom. A first knob is fixedly connected to the top end of the first threaded rod. A threaded slider is threadedly connected to the outer wall of the first threaded rod. A first sliding rod is fixedly connected inside the mounting bracket. A first slider is slidably connected to the outer wall of the first sliding rod. A mounting plate is fixedly connected to the outer wall of the first slider. The side of the mounting plate closest to the first slider is fixedly connected to the outer wall of the threaded slider. An LED display screen is fixedly connected to the inner wall of the mounting plate. A first mounting base is fixedly connected to the side of the mounting bracket away from the mounting plate. A rotating rod is fixedly connected to the inner wall of the mounting bracket.

[0008] Furthermore, the first threaded rod is located at the central axis of the mounting bracket, there are two first slide rods, the two first slide rods are symmetrically arranged with the first threaded rod as the center, and there are two first mounting seats.

[0009] Furthermore, the folding mechanism includes a base, a limiting seat is fixedly connected to the top of the base, and the rotating rod is rotatably connected inside the limiting seat.

[0010] Furthermore, a second threaded rod is rotatably connected inside the base. One end of the second threaded rod passes through the outer wall of the mounting bracket and extends outward. A second knob is fixedly connected to the end of the second threaded rod away from the base.

[0011] Furthermore, a second sliding rod is fixedly connected to the inner wall of the base, a second slider is slidably connected to the outer wall of the second sliding rod, and the inner wall of the second slider is threadedly connected to the outer wall of the second threaded rod.

[0015] This utility model has the following beneficial effects:

[0016] 1. This utility model involves rotating a first knob, which in turn rotates a first threaded rod. The rotation of the first threaded rod causes a threaded slider to move along the first threaded rod, which in turn moves a mounting plate. The first sliding rod and the first slider ensure the stability of the mounting plate during movement. The mounting plate then moves the LED display screen, thereby adjusting the height of the LED display screen to ensure that drivers of various vehicle types can clearly see the displayed information, effectively reducing traffic congestion and accidents caused by emergencies or road construction.

[0017] 2. This utility model utilizes a second knob rotated clockwise. The second knob then rotates the second threaded rod, causing the second slider to move along the second slide bar towards the limiting seat. The second slider moves the second mounting base, which in turn moves the left end of the connecting rod. The right end of the connecting rod then pushes the first mounting base, which in turn moves the mounting frame, causing it to rotate around the limiting seat. The mounting frame then moves the height adjustment mechanism, gradually moving the LED display screen on the height adjustment mechanism towards a vertical position, thus achieving a warning effect. Conversely, rotating the second knob counterclockwise allows the mounting frame to fit snugly against the base, reducing the device's footprint and facilitating transportation.
