Vehicle-mounted LED display screen

Abstract

The invention relates to the technical field of LED display screens, and discloses a vehicle-mounted LED display screen which comprises a vehicle seat, a fixing frame and a vehicle-mounted LED display screen body. The fixing frame is fixedly installed on the left side of the vehicle seat. The vehicle-mounted LED display screen body is installed in the fixing frame. Ventilation mechanisms are arranged at the upper end and the lower end of the vehicle-mounted LED display screen body correspondingly. An air blowing mechanism and a collision mechanism are arranged in the fixing frame. Each ventilation mechanism comprises a rubber cylindrical sleeve, an oval roller, a roller shaft and a reset spring, wherein the upper end and the lower end of the rubber cylindrical sleeve are fixedly connected with the inner wall of the fixing frame and the vehicle-mounted LED display screen body correspondingly, the oval roller is connected outside the roller shaft in a sleeving mode, the front end and the rear end of the roller shaft are fixedly connected with the front inner wall and the rear inner wall of the fixing frame correspondingly, and the roller shaft is positioned in the rubber cylindrical sleeve. According to the vehicle-mounted LED display screen, the collision mechanism can move rightwards under the action of inertia, so that the air pressure is increased, a conical air nozzle is opened, airflow is blown out, and heat dissipation is conducted on the vehicle-mounted LED display screen.

Description

technical field [0001] The invention relates to the technical field of LED display screens, in particular to a vehicle-mounted LED display screen. Background technique [0002] The vehicle-mounted LED display requires high luminous brightness because it is fixed in the car. Part of the electrical energy will be converted into heat energy during use of its components. In addition, the display will also absorb heat when it is exposed to sunlight. The display is used at high temperatures for a long time. It will lead to abnormal performance of the electronic components in the display screen and cause failure, and the structural parts will age and crack due to heat, which will reduce the service life of the display screen. [0003] Secondly, especially in summer, the temperature inside the car is high, and the sun is shining on the car LED display, and the air in the car is not circulated, so it is easy to cause damage to the car LED display and reduce the service life.
