Description

Technical Field

[0001] This utility model relates to the technical field of display screens, and more specifically, to a vehicle-mounted Mini LED display screen. Background Technology

[0002] In-vehicle displays, specifically designed for automobiles, are cleverly integrated into the vehicle's interior and form a core component of the car's audio-visual system. Typically, in-vehicle displays are cleverly embedded within the car's center console; however, this installation environment restricts internal airflow, making it difficult to dissipate the heat generated during operation quickly and effectively.

[0003] Based on this, we provide a vehicle-mounted Mini LED display. Utility Model Content

The housing is disposed on the back of the display screen, the heat dissipation mechanism is disposed inside the housing, and the display screen is disposed on the front of the housing. The display screen includes multiple Mini LED devices disposed on a carrier plate. The heat dissipation mechanism includes a pair of sliding rods, a slider, a flexible hose, a fan, a filter plate, and a driving component. The two sliding rods are fixedly disposed inside the housing, the slider is slidably connected between the two sliding rods, the fan is disposed at the top of the housing, the flexible hose is connected between the fan and the slider, the filter plate is disposed at the bottom of the housing, and the driving component is disposed inside the housing for driving the slider to move left and right on the sliding rods.
