Embodiment 1～2

[0074] Soda lime silicate float glass with a thickness of 2.1mm produced by Fuyao Group is used as the substrate. After cutting, edging, washing and drying, it enters the magnetron sputtering coating line for coating deposition. Two pieces The transparent nano-film and the low-emissivity (Low-E) coating including two silver layers are respectively deposited on the glass substrate. After the deposition is completed, the two glass substrates respectively deposited with the transparent nano-film and the low-e coating are matched. According to the high-temperature forming process of automobile glass, a piece of PVB film with a thickness of 0.76 mm is sandwiched in the middle, and the laminated glass plate of the present invention is made through the initial pressure and high-pressure process of the combined sheet and the installation of accessories in other processes.

Embodiment 3～5

[0080] Soda lime silicate float glass with a thickness of 1.6mm produced by Fuyao Group is used as the substrate. After cutting, edging, washing and drying, it enters the magnetron sputtering coating line for coating deposition. The transparent nano film and the low-emissivity coating in Table 2 are respectively deposited on the two surfaces of the glass substrate of mm. After the deposition is completed, it is matched with a glass substrate of 2.1 mm. A piece of PVB film with a thickness of 0.76 millimeters is installed to make the laminated glass plate of the present invention through initial pressure and high-pressure process of lamination and accessories of other processes.

Abstract

The invention relates to the technical field of head-up display, especially relates to vehicle head-up display glass, and specifically relates to head-up display laminated glass capable of realizing a thermal insulation function. The head-up display laminated glass capable of realizing the thermal insulation function comprises an inner glass plate, an outer glass plate and a middle diaphragm clamped between the inner glass plate and the outer glass plate. The surface, most far away from the middle diaphragm, of the inner glass plate is deposited by a transparent nanofilm capable of reflecting P-polarized light. The transparent nanofilm comprises at least one laminated structure of a high refractive index layer / a low refractive index layer deposited in sequence from the surface of the inner glass plate out. The surface, closest to the middle diaphragm, of the outer glass plate or the surface, closest to the middle diaphragm, of the inner glass plate is deposited by a low-radioactive coated film. The head-up display laminated glass capable of realizing the thermal insulation function both has a head-up display (HUD) function and has an infrared-ray-reflection heat insulation function; and head-up display images are clear and have no double images.

Description

[0001] Technical field: [0002] The invention relates to the technical field of head-up displays, in particular to head-up display glass on automobiles, in particular to a heat-insulating head-up display laminated glass. [0003] Background technique: [0004] With the development of science and technology, head-up display (HUD, Head Up Display) systems are increasingly used in automobiles. The head-up display system on the car can display important driving information, such as speed, engine speed, fuel consumption, tire pressure, navigation and information of external smart devices in the driver's field of vision on the front windshield in real time, so that driving The driver can see the driving information without bowing his head, so as to avoid distracting the road ahead; at the same time, the driver does not have to adjust his eyes between observing the distant road and the nearby instrument, which can avoid eye fatigue and greatly improve the Enhance driving safety and ...
