The virtual image reflected by the free-form surface mirror below the screen enters human eyes after being reflected by the coating film, and is finally reflected into an image suspended in front of the automobile. Because the coated reflecting screen needs to be irradiated by sunlight for a long time, the temperature can reach more than 60 ℃ when the coated reflecting screen is continuously irradiated in a vehicle in summer; meanwhile, when the air conditioner in the automobile works, the temperature difference between the inside and the outside of the windshield can reach more than 20 ℃ at most; therefore, the coating layer is required to have stable UV resistance, heat resistance and temperature difference resistance, and the influence of film cracking and film stripping on the display effect of the coating layer is avoided.

in the heating stage, the second heat conduction plate (129) is attached to the top of the shell (19), at the moment, the object table (11) can be heated by heat at the fastest speed, when the temperature shown by the second temperature sensor (126) is close to the preset temperature, the second heat conduction plate (129) is moved downwards, and the temperature of the bottom of the object table (11) is finally adjusted to the preset temperature by using a temperature equalizing cavity (128) between the second heat conduction plate (129) and the top of the shell (19) as a buffer; the object stage (11) and the top of the shell (19) are made of heat conducting materials, so that heat inside the shell (19) can be efficiently conducted to the bottom of the plated film (7);
in the heating process, the first temperature sensor (124) monitors the front temperature of the plated membrane (7) in real time, and the heat dissipation capacity of the upper end of the fin (123) can be adjusted by adjusting the input power of the heating plate (121), so that the front temperature of the plated membrane (7) reaches an experimental set value T1; then, the power of the radiator (125) is adjusted according to the detected temperature of the second temperature sensor (126), and the redundant heat in the heat insulation cavity (122) is discharged through the air outlet (1252), so that the temperature of the back surface of the plated film (7) is reduced to an experimental set value T2; the T1 and the T2 can simulate the difference of the internal and external environmental temperatures of the film-coated sheet (7) in the actual use process;
after the temperature of the front side and the back side of the plated film (7) is adjusted, the movable platform (31) and the rotating frame (32) are adjusted, so that the UV rays generated by the light source (33) are irradiated to the upper surface of the plated film (7) at an experimental preset angle C1 to simulate the sunlight;
in the experimental process, an operator can observe the experimental condition inside the device at any time by aligning eyes with the protective glass lens (62), and the condition on the far and near multiple conveyor belts (2) can be conveniently observed at the optimal angle by turning the observation window (6).
