[0047] The specific embodiments of this disclosure will be described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are for illustration and explanation only and are not intended to limit this disclosure.

[0048] In the description of this disclosure, it should be understood that the terms "upper," "lower," "left," "right," "top," "bottom," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this disclosure and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or a specific orientational structure and operation, and therefore should not be construed as a limitation of this disclosure. For example, see [link to relevant documentation]. Figure 1 , Figure 1 The area above the plane of the image is considered "above". Figure 1 The direction above in the drawing is "below," and "inside" and "outside" refer to the inside and outside of the corresponding structural outline. Furthermore, terms such as "first" and "second" are used only for descriptive distinction and should not be interpreted as indicating or implying relative importance.

[0049] In the description of this disclosure, it should also be noted that, unless otherwise expressly specified and limited, the terms "set up," "connect," "link," and "install" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this disclosure according to the specific circumstances.

[0050] As one implementation method, such as Figures 1 to 5 As shown, this disclosure provides a vehicle windshield, including a glass body 10, a display screen 20, and a control system. The glass body 10 includes an outer glass 11 and an inner glass 12 disposed opposite to each other along the thickness direction of the glass body 10. The outer glass 11 has a first recess 111 with an opening facing the inner glass 12, and the inner glass 12 has a second recess 121 with an opening facing the outer glass 11. The outer glass 11 and the inner glass 12 can be connected so that the first recess 111 and the second recess 121 can together form a receiving cavity for accommodating the display screen 20. The display screen 20 is electrically connected to the control system.

[0051] By using the above technical solution, the display screen 20 is integrated into the glass body 10, allowing the driver to obtain driving information (such as speed, navigation instructions, traffic sign recognition, etc.) without moving their eyes, thereby reducing the risk of traffic accidents caused by eye shift.

[0052] Furthermore, since the first recess 111 of the outer glass 11 and the second recess 121 of the inner glass 12 can together form a receiving cavity for accommodating the display screen 20, when assembling the display screen 20, the display screen 20 can be placed inside the outer glass 11 or the inner glass 12 first, so that part of the display screen 20 protrudes from the outer glass 11 or the inner glass 12 in the thickness direction of the glass body 10. Then, the outer glass 11 and the inner glass 12 are aligned. During the alignment of the outer glass 11 and the inner glass 12, the protruding part of the display screen 20 can play a guiding role, reducing the assembly difficulty of the outer glass 11 and the inner glass 12 and improving the assembly accuracy of the outer glass 11 and the inner glass 12.

[0053] Alternatively, the display screen 20 can be a transparent combiner screen, and micro-projection technology can be used to project the processed information onto the display screen 20.

[0054] As one implementation method, such as Figures 1 to 5 As shown, the vehicle's windshield also includes a sensor group (not shown) and a temperature regulation assembly 30. The sensor group is used to detect the temperature of the cavity, and the temperature regulation assembly 30 is used to regulate the temperature of the cavity. The temperature regulation assembly 30 and the sensor group are electrically connected to the control system.

[0055] Through the coordination between the sensor group, temperature regulation component 30, and control system, the control system can receive data collected from the sensor group and adjust the operating state of the temperature regulation component 30 accordingly. For example, when the temperature sensor detects that the temperature inside the cavity is lower than a preset value, the control system can activate the heating function by controlling the temperature regulation component 30, thereby raising the temperature inside the cavity. This configuration provides heating for the windshield in cold weather, effectively preventing frost or snow accumulation, ensuring clear visibility, and providing a good operating environment for electronic components.

[0056] Optionally, both the first heating film layer 31 and the second heating film layer 32 are composed of uniformly distributed conductive nanowires. These conductive nanowires intertwine to form a mesh structure, which can ensure the uniformity of heating without affecting the light transmittance of the glass.

[0057] Optionally, the display screen 20 can be a large display screen 20, which can be understood as a large projection display area on the entire windshield. This configuration allows occupants to view driving information and supports multi-user viewing angles.

[0058] The display screen 20 can also be a small display screen 20, which can be understood as a small projection display area located in a specific area on the windshield (directly in front of the driver's cab or directly in front of the passenger's cab). This setting allows the driver or passenger to view driving information without interfering with normal driving vision and avoids information overload.

[0059] Regarding the embodiment of the display screen 20 as a large display screen 20, such as Figures 2 to 3 As shown, the sensor group includes a temperature sensor (not shown) and a temperature and humidity sensor (not shown). The temperature regulation component 30 includes a first heating film layer 31 and a second heating film layer 32. The vehicle windshield also includes a first heat insulation layer 40 and a second heat insulation layer 41. The display screen 20 has a first heat insulation layer 40 on the side near the outer glass 11 and a second heat insulation layer 41 on the side near the inner glass 12. The first heat insulation layer 40 is connected to the first heating film layer 31 on the side away from the display screen 20. The side of the first heat insulation layer 40 away from the second heat insulation layer 41 is configured to be able to adhere to the outer glass 11. The side of the second heat insulation layer 41 away from the display screen 20 is connected to the second heating film layer 32. The side of the second heating film layer 32 away from the second heat insulation layer 41 is configured to be able to adhere to the inner glass 12. A temperature sensor is provided on the cavity wall of the first cavity 111 to detect the temperature inside the first cavity 111. A temperature and humidity sensor is provided on the cavity wall of the second cavity 121 to detect the temperature and humidity inside the second cavity 121.

[0060] The temperature sensor is located inside the first cavity 111 and is used to monitor the influence of the external environment on the internal temperature of the first cavity 111. When the detected temperature is lower than a set threshold, it indicates that there may be a risk of frost or snow accumulation.

[0061] The temperature and humidity sensor is located in the second cavity 121 and is used to monitor the influence of the vehicle interior environment on the temperature and humidity inside the second cavity 121. When the humidity is high and the temperature is close to the dew point (the temperature at which water vapor in the air begins to condense into water droplets), fogging may occur.

[0062] By setting temperature sensors and temperature and humidity sensors, the temperature in the first cavity 111 and the temperature and humidity in the second cavity 121 can be monitored respectively, and the data can be transmitted to the control system. This allows for a precise understanding of the actual temperature conditions of each cavity.

[0063] The control system can receive data from the temperature sensor and the humidity sensor to determine whether to activate and how to adjust the working state of the first heating film layer 31 and the second heating film layer 32. For example, in cold weather, if the temperature sensor detects that the temperature inside the first cavity 111 is too low, the first heating film layer 31 can be activated to heat the area and maintain a clear view. Similarly, if the humidity sensor detects that the humidity is high and the current temperature is close to the dew point temperature, the second heating film layer 32 can be activated to increase the dew point temperature difference and suppress water vapor condensation.

[0064] The first heat insulation layer 40 and the second heat insulation layer 41 help isolate the temperature difference between the first cavity 111 and the second cavity 121, preventing the operating environment of electronic devices such as the display screen 20 from being affected by drastic fluctuations in external temperature. At the same time, it can effectively improve heating efficiency and reduce unnecessary energy consumption.

[0065] Regarding the embodiment where the display screen 20 is a small display screen 20, such as Figures 4 to 5 As shown, the display screen 20 can be installed at any position within the receiving cavity. For example, in an exemplary embodiment provided in this disclosure, the sensor group includes a temperature sensor (not shown) and a temperature and humidity sensor (not shown). The temperature regulation assembly 30 includes a first heating film layer 31 and a second heating film layer 32. The vehicle windshield also includes a first heat insulation layer 40, a second heat insulation layer 41, and a third heat insulation layer 42. The display screen 20 is positioned close to the receiving cavity. The third heat insulation layer 42 includes a first plate 421 and a second plate 422 that are interconnected. The first plate 421 is adjacent to the display screen 20 in the extending direction of the display screen 20, and the second plate 422 is adjacent to the display screen 20 in a direction perpendicular to the extending direction of the display screen 20. The first plate 421 and the second plate 422 together surround the display screen 20, and the display screen 20 is close to the outer glass. A first heat insulation layer 40 is provided on one side of the outer glass 11. A second heat insulation layer 41 is provided on the side of the display screen 20 near the inner glass 12. One side of the first heating film layer 31 is connected to the first heat insulation layer 40 and the third heat insulation layer 42, and the other side of the first heating film layer 31 is attached to the outer glass 11. One side of the second heating film layer 32 is connected to the second heat insulation layer 41 and the third heat insulation layer 42, and the other side of the second heating film layer 32 is attached to the inner glass 12. A temperature sensor is provided on the cavity wall of the first cavity 111 to detect the temperature inside the first cavity 111. A temperature and humidity sensor is provided on the cavity wall of the second cavity 121 to detect the temperature and humidity inside the second cavity 121. The sum of the thickness of the second heat insulation layer 41, the thickness of the first heat insulation layer 40, and the thickness of the display screen 20 is equal to the thickness of the third heat insulation layer 42.

[0066] In one embodiment of this disclosure, such as Figures 4 to 5As shown, the display screen 20 has two second panels 422 on each of its opposite sides, and the two second panels 422 and the first panel 421 form a U-shape. That is, the display screen 20 is located in the middle of the side cavity wall extending along the length direction of the receiving cavity or in the middle of the side cavity wall extending along the width direction of the receiving cavity.

[0067] In other embodiments, the first plate 421 and the second plate 422 may also be L-shaped, that is, the display screen 20 may be located at the bend between the two side walls of the receiving cavity.

[0068] In one implementation, the control system includes a processor and a comparator electrically connected to the processor. The comparator is electrically connected to a temperature sensor and a temperature and humidity sensor. The comparator is used to compare the temperature signal received from the temperature sensor with a preset temperature threshold and to compare the temperature and humidity signal received from the temperature and humidity sensor with a preset temperature and humidity threshold. The processor is electrically connected to a first heating film layer 31 and a second heating film layer 32.

[0069] Through the coordinated operation of the processor, comparator, sensor group, and temperature regulation component 30, precise monitoring and automated regulation of the temperature in the first cavity 111 and the second cavity 121 are achieved.

[0070] In one embodiment, the outer glass 11 has a first flange edge (not shown) formed on the side near the opening of the first recess 111, and the inner glass 12 has a second flange edge (not shown) formed on the side near the opening of the second recess 121. The second flange edge is configured to fit snugly against the first flange edge. This configuration reduces the difficulty of connecting the outer glass 11 and the inner glass 12, and also improves the structural stability and sealing performance of the entire windshield.

[0071] In one embodiment, the inner glass 12 is coated with a nano anti-fog coating on the side away from the outer glass 11, and the outer glass 11 is coated with a nano anti-oil coating on the side away from the inner glass 12.

[0072] The nano-anti-fog coating is composed of hydrophilic nanoparticles. These particles can form a uniform water film on the glass surface, preventing water vapor from condensing into fine droplets. In addition, due to the presence of the water film, light can pass through the glass evenly, reducing light scattering caused by droplets and maintaining good light transmittance.

[0073] The nano-oil-resistant coating is composed of nanomaterials with low surface energy and oleophobic properties. These materials can significantly reduce the adhesion of oil, dust, and other contaminants to the glass surface. Even if a small amount of contaminants adheres, it can be easily removed by simple wiping or rainwater rinsing, reducing the need for daily maintenance.

[0074] As one implementation method, such as Figures 1 to 5As shown, the vehicle's windshield also includes a photovoltaic panel 60, which is located in the first recess 111. The photovoltaic panel 60 is an annular structure extending circumferentially along the first recess 111 and is used for electrical connection with the vehicle's battery.

[0075] The photovoltaic panel 60 is placed in the first recess 111 to prevent damage to the photovoltaic panel 60 caused by the external environment (such as the impact of foreign objects such as stones and branches when the vehicle is driving, or the wear and tear on the surface of the photovoltaic panel 60 caused by impurities such as wind, sand and dust), which helps to improve the service life of the photovoltaic panel 60.

[0076] This design utilizes solar energy to provide additional power to the vehicle. This not only improves energy efficiency but also enhances the functionality and sustainability of the windshield.

[0077] In the embodiment where the display screen 20 is a large display screen 20, the photovoltaic panel 60 is arranged as shown in 2 and Figure 3 As shown, the first heating film layer 31 can avoid the photovoltaic panel 60, that is, the area of ​​the first heating film layer 31 is smaller than the area of ​​the second heating film layer 32.

[0078] In the embodiment where the display screen 20 is a large display screen 20, the photovoltaic panel 60 is arranged as shown in 4 and Figure 5 As shown, the first heating film layer 31 can avoid the photovoltaic panel 60, that is, the area of ​​the first heating film layer 31 is smaller than the area of ​​the second heating film layer 32.

[0079] In one implementation, the vehicle's windshield also includes an ETC electronic tag module (not shown), which is disposed on the cavity wall of the first recess 111. This design not only optimizes space utilization but also improves the reliability and aesthetics of the ETC electronic tag module.

[0080] In addition, the ETC electronic tag module placed in the first cavity 111 is well protected and is not easily affected by the external environment (such as rain, dust, ultraviolet rays, etc.), which can extend the service life of the ETC electronic tag module.

[0081] Optionally, a nanomaterial coating can be applied around the ETC electronic tag module to enhance and optimize the radio frequency signal.

[0082] Optionally, the nanomaterial coating can be a metal nanoparticle coating, a carbon-based nanomaterial coating, or a dielectric nanomaterial coating; this disclosure does not impose any limitations on this.

[0083] The preferred embodiments of this disclosure have been described in detail above with reference to the accompanying drawings. However, this disclosure is not limited to the specific details of the above embodiments. Within the scope of the technical concept of this disclosure, various simple modifications can be made to the technical solutions of this disclosure, and these simple modifications all fall within the protection scope of this disclosure.

[0084] It should also be noted that the various specific technical features described in the above specific embodiments can be combined in any suitable manner without contradiction. In order to avoid unnecessary repetition, this disclosure will not describe the various possible combinations separately.

[0085] Furthermore, various different embodiments of this disclosure can be combined in any way, as long as they do not violate the spirit of this disclosure, they should also be regarded as the content disclosed in this disclosure.
