Vehicle-mounted display screen

Abstract

The invention relates to the technical field of LED display screens, and discloses a vehicle-mounted display screen which comprises a vehicle arm-chair, a vehicle-mounted display device is arranged on the left side of the vehicle arm-chair, the vehicle-mounted display device comprises a square frame, a cylindrical heat dissipation barrel, a heat dissipation mechanism and a vehicle-mounted display screen, the square frame is fixedly installed in the left side of the vehicle arm-chair, the vehicle-mounted display screen is fixedly installed in the square frame, the cylindrical heat dissipation barrel is fixedly installed in the square frame and penetrates through the upper side and the lower side of the square frame, and the heat dissipation mechanism is installed in the cylindrical heat dissipation barrel. The heat dissipation mechanism comprises a transverse rod, an extrusion spring, a one-way ball, a conical cylindrical sleeve, a jumping spring, a jumping mechanism, a fixing rod, a transverse plate, an S-shaped memory metal plate, a baffle and a special-shaped air bag. According to the vehicle-mounted display device, air moves upwards through the cylindrical heat dissipation barrel, so that cold air moves upwards, the purpose of heat dissipation is achieved, and the service life of the vehicle-mounted display device is prolonged.

Description

technical field [0001] The invention relates to the technical field of LED display screens, in particular to a display screen for vehicles. Background technique [0002] Vehicle-mounted display screens are installed in many cars, especially long-distance buses, which have a large number of passengers and take a long time, so many long-distance buses will install vehicle-mounted display screens, but the vehicle-mounted display screens are fixed in the car. It needs a strong luminous degree to be able to watch under the condition of high brightness in the car, but when the luminous degree of the vehicle-mounted display is high, the electric energy of the electronic components inside it will be converted into heat energy, and secondly, the vehicle-mounted display is in the vehicle. The process will change with the change of the driving direction of the vehicle, so the car display screen may be directly irradiated by the sun, and there are many people in the car, and the tempera...

Problems solved by technology

[0002] Vehicle-mounted display screens are installed in many cars, especially long-distance buses, which have a large number of passengers and take a long time, so many long-distance buses will install vehicle-mounted display screens, but the vehicle-mounted display screens are fixed in the car. It needs a strong luminous degree to be able to watch under the condition of high brightness in the car, but when the luminous degree of the vehicle-mounted display is high, the electric energy of the electronic components inside it will be converted into heat energy, and secondly, the vehicle-mounted display is in the vehicle. The process will change with the change of the driving direction of the vehicle, so the car display screen may be directly irradiated by the sun, and there are many people in the car, and the temperature inside the car is high, so the car display screen is in a high temperature state for a long time , which will cause the aging of its internal electronic components and reduce the service life of the car display
