Description

Vehicle window glass and vehicle

[0001] The present application claims priority to the Chinese patent application No. 202410477411.3, filed on April 19, 2024, entitled "Vehicle window glass and vehicle", the entire content of which is incorporated herein by reference. TECHNICAL FIELD

[0002] The present application relates to the technical field of glass, in particular to a vehicle window glass and a vehicle. BACKGROUND

[0003] With the popularization of vehicle intelligentization, automation and networking technologies, the number of cameras required by vehicles has developed from only one camera to two, three or even more cameras, and the requirements for the image clarity and position accuracy of the captured objects have also been greatly improved. These cameras located in the vehicle need to pass through the vehicle window glass to obtain the real-time view of the vehicle during driving. Therefore, the optical transmission area in the vehicle window glass for the camera to obtain the external view of the vehicle needs to have a high enough optical quality, such as a high visible light transmittance, a low diopter, a small secondary image deviation, etc.

[0004] Among them, the diopter reflects the maximum allowed optical distortion value of the optical transmission area. In order to realize the functions of advanced driver assistance system (ADAS) and even autonomous driving, more and more automobile manufacturers require the design of the optical transmission area to have a diopter of not more than 150 mdpt, and even some require not more than 100 mdpt. It is almost impossible for traditional vehicle window glass to achieve such a low level of optical distortion, because the traditional vehicle window glass uses ceramic ink to print around the optical transmission area, and the optical transmission area is not printed with ceramic ink, so that after the subsequent bending forming process above 560℃, the area printed with ceramic ink has a higher temperature than the optical transmission area, thereby forming a temperature gradient of dozens of degrees Celsius, resulting in a kinetic difference in the bending forming of the vehicle window glass, which causes optical distortion around the junction between the area printed with ceramic ink and the area without ceramic ink, which is more obvious within a range of 30mm around the junction, ultimately making the diopter of the optical transmission area surrounded by ceramic ink possibly greater than 400 mdpt.

[0081] Comparative Examples 1-15 and Example 1-15 are as follows:

[0082] Two pieces of silicate glass with a thickness of 2.1 mm were prepared, and each piece of the silicate glass was bend-formed according to a production process for automotive glass, i.e., a bend-forming process at a temperature of at least 560°C, such as a gravity bend-forming process, a press bend-forming process, or the like.

The measurement results are listed in Table 1.

[0083] Comparative Example 1-15: only the first shielding layer 20 is provided, and the optical transmission region 103 is formed by the first shielding layer 20;

[0084] Example 1-15: the first shielding layer 20 and the second shielding layer 30 are provided, and the optical transmission region 103 is formed by the first shielding layer 20 and the second shielding layer 30;

[0085] Table 1: Measurement results of Comparative Examples 1-15 and Example 1-15

[0086] In Table 1, the data were measured by using a LABSCAN-SCREEN system of ISRA VISION Co., Ltd. The horizontal refractive power was measured by using a filter parameter of “3 / 2 / 0 30 / 4 / 4” and a detection angle of 26.8° to detect the maximum refractive power of the optical transmission region 103 in the width direction (X-axis direction) of the vehicle window glass 100. The vertical refractive power was measured by using a filter parameter of “3 / 2 / 0 30 / 4 / 4” and a detection angle of 26.8° to detect the maximum refractive power of the optical transmission region 103 in the height direction (Y-axis direction) of the vehicle window glass 100. In Table 1, the positive and negative signs of the horizontal and vertical refractive powers only indicate the direction of the optical distortion, and a positive sign indicates that the direction of the optical distortion is convex outward, and a negative sign indicates that the direction of the optical distortion is concave inward. The absolute values of the horizontal and vertical refractive powers indicate the degree of the optical distortion, and a larger absolute value indicates a greater degree of the optical distortion.

[0087] As can be seen from Table 1, the absolute value of the horizontal refractive power of the optical transmission zone 103 of the comparative examples 1-15 is greater than 200 mdpt, or even greater than 300 mdpt, which is designed by the traditional design. Since the vehicle window glass is usually installed in a vertical direction as a front windshield to minimize the visual distortion and visual fatigue of the driver, the optical distortion of the optical transmission zone 103 in the X-axis direction has the greatest impact on the image quality of the sensor 200, and the degree of optical distortion of the acquired image is greater. Compared with the comparative examples 1-15, the vehicle window glass 100 of the embodiments 1-15 is designed according to the present application, which can greatly reduce the absolute value of the horizontal refractive power of the optical transmission zone 103 to less than or equal to 100 mdpt, preferably less than or equal to 85 mdpt, more preferably less than or equal to 70 mdpt, or even less than or equal to 60 mdpt. Therefore, the degree of optical distortion of the optical transmission zone 103 of the embodiments 1-15 in the X-axis direction is significantly improved, so that the acquired image does not have local abnormal distortion.

[0088] In Table 1, the absolute value of the vertical refractive power of the optical transmission zone 103 of the embodiments 1-15 is less than or equal to 50 mdpt, preferably less than or equal to 40 mdpt, more preferably less than or equal to 30 mdpt, or even less than or equal to 25 mdpt. Compared with the absolute value of the vertical refractive power of the optical transmission zone 103 of the comparative examples 1-15, it is reduced by at least 30 mdpt, or at least 40 mdpt, or at least 50 mdpt, or at least 60 mdpt, or even at least 100 mdpt, or more even at least 120 mdpt. Therefore, the degree of optical distortion of the optical transmission zone 103 of the embodiments 1-15 in the Y-axis direction is significantly improved, so that the acquired image does not have local abnormal distortion.
