Description

Technical Field

[0001] The present invention relates to the technical field of vehicle-mounted screens, and particularly to a multi-angle adjustment device for vehicle-mounted advertising screens. Background Technique

[0002] A vehicle-mounted screen is installed on a vehicle and is a device that uses a dedicated power supply, a control card, and unit boards to display text, pictures, animations, and videos through dot matrix lighting and extinguishing. It is a set of LED vehicle-mounted display systems that have emerged independently with the rapid development of LED displays. Compared with ordinary door head screens and fixed LED displays, it has higher requirements for stability, anti-interference, anti-vibration, dust prevention, etc. Usually, it is a liquid crystal display with external sound, and can read SD cards, USB, and Bluetooth and other functions.

[0003] Vehicle-mounted advertising screens are generally installed on both sides or the top of the vehicle, and in most cases, they are fixedly installed at a designated position or a designated angle. When adjusting the angle or height of the advertising screen, it is necessary to loosen the fasteners, and then adjust the advertising screen to a suitable position or angle, and then tighten the fasteners again to fix the advertising screen, which makes the adjustment more inconvenient. And most of the existing adjustment devices can only perform angle adjustment in a certain direction, making the functionality relatively single. Summary of the Invention

By controlling the fourth motor 26, the fourth motor 26 drives the second lead screw 27 to rotate, so that the rotation of the second lead screw 27 can drive the second slider 28 threadedly connected thereto to slide and adjust. Since the two second sliders 28 are threadedly connected to the second lead screw 27 in opposite directions, the two second sliders 28 slide and adjust in the opposite direction, so that the sliding adjustment of the second slider 28 can make the sliding plate 31 slide and adjust in the first limiting groove 30, so that the third connecting rod 29 can drive the sliding plate 31 to slide and adjust on the surface of the side wall 25, so that the sliding plate 31 can drive the first clamping block 34 and the second clamping block 35 to adjust the distance therebetween, so that the first clamping block 34 and the second clamping block 35 clamp and fix the advertising screen.
