Example Embodiment

[0030] The content of the present invention will be further described below in conjunction with the accompanying drawings.

[0031] Such as figure 1 with figure 2 As shown, the laminated heat-insulating glass with locally high infrared transmission according to the present invention can be used with lidar and / or infrared cameras. The laminated heat-insulating glass includes an outer glass plate 1, an inner glass plate 2 and a clip The thermoplastic intermediate layer 3 is arranged between the outer glass plate 1 and the inner glass plate 2, the outer glass plate 1 has a first surface 11 and a second surface 12, and the inner glass plate 2 has a third surface 21 and a fourth surface 22. The second surface 12 and the third surface 21 face each other, and the thermoplastic intermediate layer 3 bonds the second surface 12 and the third surface 21 together; usually, the outer glass plate 1 is located Outside of the car, the inner glass plate 2 is located inside the car. The laminate...

Abstract

The invention relates to the field of glass products, in particular to a front windshield mounted on an automobile, and particularly provides a locally high-infrared-ray-transmission interlayer heat insulation glass capable of being used in cooperation with a laser radar and/or an infrared camera. The laminated heat-insulating glass comprises an infrared high-transmittance area formed by a first transparent nano-film and an infrared low-transmittance area formed by a second transparent nano-film, the infrared high-transmittance region has a transmittance of at least 92% in the wavelength rangeof 850-1550 nm, and the infrared low-transmittance region has a transmittance of at most 25% in the wavelength range of 780-2500 nm. According to the invention, the total solar transmissivity of thelaminated heat-insulating glass does not exceed 55%; the use requirement that attenuation of signals of the laser radar or the infrared camera penetrating through the interlayer heat insulation glassis not higher than 3 dB is met, normal work of the laser radar or the infrared camera is guaranteed, air conditioner energy consumption can be obviously reduced, and the comfort degree of a driver andpassengers is improved.

Description

Technical field: [0001] The invention relates to the field of glass products, especially the front windshield installed on automobiles, and specifically provides a laminated heat-insulating glass with local high infrared penetration that can be used in conjunction with laser radar and / or infrared cameras. Background technique: [0002] With the rise of intelligent networked cars, multi-function cameras (MFK) have become a must-have for high-end models. Due to the gradual popularization of intelligent driving, the resolution of multi-function cameras in cars has also been greatly improved, and even sensors such as lidar Installed on the inner side of the front windshield of the car, these have higher requirements for the front windshield in the area where the multi-function camera or lidar is located in terms of light transmittance, diopter and radius of curvature. [0003] The front windshield of a car is usually laminated glass, which includes an outer glass plate, a thermo...
