Abstract
Description
Technical Field
[0001] This application relates to vehicle technology, and more particularly to a windshield assembly and a vehicle. Background Technology
[0002] As cars become increasingly intelligent, the accuracy of data collection based on vision systems is required to be very high. Some models typically place cameras behind the windshield, so the data collected by the cameras must be collected through the windshield.
[0003] In related technologies, windshields are typically curved, and their glass structure is "laminated glass": two layers of glass with a layer of polyvinyl butyral (PVB) film sandwiched between them. When light passes through the windshield, ghosting occurs due to the reflection and refraction effects of the glass (usually expressed as the sub-phase deviation angle; the larger the sub-phase deviation angle, the more severe the ghosting). Furthermore, the glass thickness and the glass mounting angle also affect the sub-phase deviation angle. Therefore, deviations occur during camera data acquisition, thus affecting the accuracy of the acquired data.
[0004] In traditional car models, the way to reduce the phase deviation angle without changing the shape is usually to add a wedge-shaped PVB film to increase the wedge angle of the glass. However, its structure is complex and difficult to process and manufacture, resulting in a low yield. Utility Model Content
[0005] In view of this, this application provides a windshield assembly and vehicle that can simplify the structure of the windshield, reduce the phase deviation angle of the windshield, and improve the accuracy of the data collected by the camera.
[0006] To achieve the above objectives, this application provides a windshield assembly and vehicle, which adopts the following technical solution:
[0007] In a first aspect, this application provides a front windshield assembly, including a windshield body and a camera assembly, wherein the camera assembly is located on the rear side of the windshield body, and the windshield body has a first viewing area and a second viewing area.
[0008] The first visible area and the second visible area are set at an interval;
[0009] The camera assembly can capture image data through the second visible area;
[0010] The radius of curvature of the second visible region is greater than that of the first visible region.
[0011] In one possible implementation, the windshield assembly provided in this application has a first visible area with a radius of curvature greater than or equal to 1500 mm and less than or equal to 5000 mm.
[0012] The radius of curvature of the second visible area is set to be greater than 5000 mm and less than or equal to 7000 mm.
[0013] In one possible implementation, the windshield assembly provided in this application has the second visible area located above the first visible area in the height direction of the windshield body.
[0014] In one possible implementation, the windshield assembly provided in this application further includes a third visible area, which is arranged in a strip around the outer periphery of the second visible area and is connected to the second visible area; the radius of curvature of the third visible area is the same as that of the second visible area.
[0015] The distance from the outer edge of the third visible area to the inner edge of the third visible area is greater than or equal to 30 mm and less than or equal to 100 mm.
[0016] In one possible implementation, the windshield assembly provided in this application has the third visible area spaced apart from the first visible area.
[0017] In one possible implementation, the windshield assembly provided in this application further includes a mounting area, through which the windshield body can be mounted to a vehicle;
[0018] The first visible area, the second visible area, and the third visible area are all located within the installation area, and the third visible area is smoothly connected to the installation area.
[0019] In one possible implementation, the windshield assembly provided in this application has at least one outer edge of the third visible area collinear with the outer edge of the mounting area.
[0020] In one possible implementation, the windshield assembly provided in this application includes a first glass and a second glass, the first glass and the second glass being bonded together, and the first glass being located in front of the second glass.
[0021] In one possible implementation, the windshield assembly provided in this application has the first visible area and the second visible area located within the first glass.
[0022] Secondly, this application provides a vehicle, including a vehicle body and a windshield assembly as described above, the windshield assembly being disposed on the front side of the vehicle body.
[0023] This application provides a windshield assembly and vehicle, wherein the windshield assembly includes a windshield body and a camera assembly. The camera assembly is located behind the windshield body, which has a first visible area and a second visible area. The first and second visible areas are spaced apart. The camera assembly can acquire image data through the second visible area. The radius of curvature of the second visible area is greater than that of the first visible area. The radius of curvature is adjusted locally only for the second visible area, i.e., the acquisition path of the camera assembly, rather than changing the radius of curvature of the entire windshield body. This avoids the complexity of traditional solutions that require adding a wedge-shaped PVB film or significantly adjusting the glass structure. Localized adjustment of the radius of curvature reduces processing difficulty, reduces manufacturing error risks, and improves yield. The radius of curvature of the second visible area is greater than that of the first visible area. A larger radius of curvature results in a smoother glass surface curvature, leading to a smaller change in the refraction angle of light passing through, thereby reducing the secondary phase deviation angle caused by surface refraction and effectively mitigating ghosting. Furthermore, by setting the first and second visible areas at an interval, conflicts with the acquisition path of the camera components are avoided, thus preventing global image deviations caused by global surface refraction in traditional solutions and directly improving the accuracy of the acquired data.

The embodiments of this application will be described in detail below with reference to the accompanying drawings.

[0036] The terms "first," "second," "third," "fourth," etc., used in the specification, claims, and accompanying drawings of this application are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence.
[0037] Furthermore, the terms “comprising” and “having”, and any variations thereof, are intended to cover non-exclusive inclusion, such that a process, method, system, product, or apparatus that includes a series of steps or units is not necessarily limited to those steps or units that are explicitly listed, but may include other steps or units that are not explicitly listed or that are inherent to such process, method, product, or apparatus.
[0038] The front of a car typically features a windshield, which is mounted on the vehicle using mounting components. As cars become increasingly intelligent, the accuracy of data collection from vision systems is crucial. Some models place the camera behind the windshield, or essentially inside the passenger compartment, meaning the data collected by the camera must pass through the windshield before being processed.
[0039] In related technologies, windshields are typically curved, and their glass structure is "laminated glass": two layers of glass with a layer of polyvinyl butyral (PVB) film sandwiched between them. When light passes through the windshield, ghosting occurs due to the reflection and refraction effects of the glass (usually expressed as the sub-phase deviation angle; the larger the sub-phase deviation angle, the more severe the ghosting). Furthermore, the glass thickness and the glass mounting angle also affect the sub-phase deviation angle. Therefore, deviations occur during camera data acquisition, thus affecting the accuracy of the acquired data.
[0040] In traditional car models, the way to reduce the phase deviation angle without changing the shape is usually to add a wedge-shaped PVB film to increase the wedge angle of the glass. However, its structure is complex and difficult to process and manufacture, resulting in a low yield.
[0041] To address the aforementioned issues, this application provides a windshield assembly and a vehicle. The windshield assembly includes a windshield body and a camera assembly. The camera assembly is located behind the windshield body. The windshield body has a first visible area and a second visible area. The first visible area and the second visible area are spaced apart. The camera assembly can collect image data transmitted through the second visible area. The radius of curvature of the second visible area is greater than the radius of curvature of the first visible area.
[0042] This approach adjusts the radius of curvature only in the second visible area, i.e., the acquisition path of the camera component, rather than changing the radius of curvature of the entire windshield. This avoids the complexity of adding a wedge-shaped PVB film or significantly adjusting the glass structure, as required by traditional solutions. Localizing the radius of curvature reduces processing difficulty, minimizes manufacturing error risks, and improves yield. The radius of curvature in the second visible area is larger than that in the first visible area. A larger radius of curvature results in a smoother glass surface curvature, leading to a smaller change in the refraction angle of light passing through, thus reducing the sub-phase deviation angle caused by surface refraction and effectively mitigating ghosting. Furthermore, by setting the first and second visible areas alternately, conflicts with the camera component's acquisition path are avoided, preventing global image deviations caused by global surface refraction in traditional solutions and directly improving the accuracy of the acquired data.
[0043] The following explains the terms mentioned above, such as subphase deviation angle, glass thickness, glass wedge angle, and radius of curvature, as well as the relationships between these terms:
[0044] In related fields, the subphase deviation angle can be calculated using the following formula:
[0045]
[0046] in:
[0047] α is the subphase deviation angle;
[0048] The angle between the light ray and the glass;
[0049] t is the thickness of the glass at the point where the light is incident;
[0050] R is the radius of curvature of the glass at the location of the incident ray;
[0051] n is the refractive index of the glass;
[0052] δ is the wedge angle of the glass;
[0053] According to the formula above, if the sub-phase deviation angle needs to be reduced, it can be achieved by increasing R, i.e., increasing the radius of curvature at that location. It can also be achieved by reducing the glass thickness; however, the thickness of the vehicle's windshield is already determined by relevant regulations, therefore, the safety of the windshield must be ensured. Traditionally, a wedge-shaped PVB film is added to change the wedge angle δ of the glass, thereby offsetting the sub-phase deviation angle, but this method is very costly.
[0054] The following explains how the embodiments of this application solve the above-mentioned technical problems: It should be noted that... Figures 1 to 3 This diagram illustrates a simplified representation of the windshield assembly and other components within the vehicle. The specific structures of the windshield assembly and other components in the vehicle are not limited to these examples. Figures 1 to 3 of examples.
[0055] This application provides a windshield assembly 30, which includes a windshield body 100 and a camera assembly 200, with the camera assembly 200 located at the rear of the windshield body 100. Here, the camera assembly 200 belongs to the prior art in related technical fields, and this application does not limit the specific structure of the camera assembly 200; it is sufficient that the camera assembly 200 can complete data acquisition. The windshield body 100 has a front side and a rear side. It is understood that, referring to… Figure 3 As shown, in Figure 3 In the direction indicated by the X arrow, the front side of the windshield body 100 is the outer side of the vehicle 20, and the rear side of the windshield body 100 can be understood as the inner side of the vehicle 20.
[0056] The windshield body 100 has a first visible area 101 and a second visible area 102; the first visible area 101 and the second visible area 102 are spaced apart; the camera assembly 200 can collect image data through the second visible area 102; the radius of curvature of the second visible area 102 is greater than the radius of curvature of the first visible area 101.
[0057] The radius of curvature of the second visible area 102 is greater than that of the first visible area 101. A larger radius of curvature results in a smoother glass surface curvature, leading to a smaller change in the refraction angle of light passing through it. This allows the camera assembly 200 to capture image data transmitted through the second visible area 102, thereby reducing the sub-phase deviation angle caused by curved surface refraction and effectively mitigating ghosting. The camera assembly 200 specifically captures image data transmitted through the second visible area 102. Because this area has a smoother curvature and a light propagation path closer to that of flat glass, it reduces image distortion caused by complex refraction in traditional curved glass, improving the accuracy of data acquisition.
[0058] The curvature adjustment is performed only on the second visible area 102, i.e. the acquisition path of the camera component 200, rather than changing the curvature radius of the windshield as a whole. This avoids the complexity of adding a wedge-shaped PVB film 10 or making significant adjustments to the glass structure as required by traditional solutions. The localized adjustment of the curvature radius reduces the processing difficulty, reduces the risk of manufacturing errors, and improves the yield.
[0059] Furthermore, the first visible area 101 can maintain its original radius of curvature, such as the curvature of a conventional windshield, ensuring that the driver's field of vision is not affected. Simultaneously, by setting the first visible area 101 and the second visible area 102 alternately, conflicts with the acquisition path of the camera component 200 are avoided, preventing global image deviations caused by global surface refraction in traditional solutions, and directly improving the accuracy of the acquired data. This arrangement satisfies the conventional requirements of the driver's field of vision while reserving independent optimization space for the camera component 200.
[0060] The above configuration allows the windshield body 100 to be formed using a unified mold process, reducing the complex steps of processing different areas and lowering manufacturing costs.
[0061] In one possible implementation, the radius of curvature of the first visible area 101 is set to be greater than or equal to 1500 mm and less than or equal to 5000 mm.
[0062] The radius of curvature of the second visible area 102 is set to be greater than 5000 mm and less than or equal to 7000 mm.
[0063] A larger radius of curvature makes the glass surface of the second visible area 102 closer to a plane, reducing the change in the refraction angle of light as it passes through, thereby significantly reducing the sub-phase deviation angle, mitigating ghosting, and improving the accuracy of image data. The radius of curvature of the first visible area 101 is set to be greater than or equal to 1500 mm and less than or equal to 5000 mm. This maintains a suitable curvature to meet the driver's visibility requirements while avoiding the complex structure of the traditional wedge-shaped PVB film 10 due to excessively small curvature, balancing functionality and manufacturing feasibility. The lower limit of the radius of curvature of the second visible area 102 (5000 mm) seamlessly connects with the upper limit of the radius of curvature of the first visible area 101 (5000 mm), ensuring that the first and second visible areas 101 are spaced apart while avoiding the processing challenges caused by abrupt changes in the radius of curvature.
[0064] Setting the upper limit of the curvature radius of the second visible area 102 to 7000mm limits it to the feasible range and prevents excessive flatness from causing insufficient structural support.
[0065] The radius of curvature (1500-5000mm) of the first visible area 101 conforms to the curvature requirements of traditional windshields, ensuring that the driver's vision is not affected, while maintaining consistency with the vehicle's styling. The larger radius of curvature of the second visible area 102 is only for the camera acquisition area, does not affect the overall appearance, and is easy to integrate into existing vehicle models.
[0066] The above-described configuration ensures that the sub-phase deviation angle α of the second visible area 102 is less than 5′, which meets the design requirements. Specific vehicle models can be calculated accordingly. This application does not impose any restrictions on the specific value of the sub-phase deviation angle of the second visible area 102.
[0067] In one possible implementation, the second visible area 102 is located above the first visible area 101 in the height direction of the windshield body 100. Alternatively, it can be understood that the second visible area 102 is located above the first visible area 101 in the height direction of the vehicle 20, meaning that the camera assembly 200 is positioned above the driver.
[0068] In the above configuration, the second visible area 102 is located above the first visible area 101, which does not affect the driver's main observation area of the road ahead, while providing an independently optimized acquisition path for the camera component 200, taking into account both safety and intelligent requirements.
[0069] In one possible implementation, the windshield body 100 further has a third visible area 103, which is arranged in a strip around the outer periphery of the second visible area 102 and is connected to the second visible area 102; the radius of curvature of the third visible area 103 is the same as that of the second visible area 102.
[0070] The distance from the outer edge of the third visible area 103 to the inner edge of the third visible area 103 is greater than or equal to 30 mm and less than or equal to 100 mm.
[0071] The third visible area 103 has the same radius of curvature as the second visible area 102, forming a continuous and smooth transition zone. The third visible area 103, which is strip-shaped around the outer periphery of the second visible area 102, provides the camera assembly 200 with a wider data acquisition range, while ensuring the uniformity of the light propagation path and improving the accuracy of the image edge area.
[0072] It should be noted here that the strip-shaped third visible area 103 can be either irregular or regular. For example... Figure 1 As shown, the outer edge of the third visible area 103 is rectangular, and the third visible area 103 completely surrounds the second visible area 102. The third visible area 103 serves as a transition zone around the second visible area 102, absorbing light refraction deviations at the edges and avoiding image distortion caused by abrupt curvature changes in traditional curved glass. The third visible area 103 is connected to the second visible area 102, ensuring that the camera assembly 200 does not experience discontinuities or abrupt changes due to area boundaries when acquiring data, thus enhancing data continuity.
[0073] In addition, the distance from the outer edge to the inner edge of the third visible area 103 is limited to 30 to 100 millimeters, which ensures sufficient transition space to optimize optical performance while avoiding the increased manufacturing complexity or glass structure instability caused by excessive width.
[0074] In one possible implementation, the third visible area 103 is spaced apart from the first visible area 101. This avoids interference between areas with different radii of curvature, ensures the stability of the driver's main field of vision's radius of curvature, and optimizes the acquisition path of the camera assembly 200 while maintaining safety.
[0075] Furthermore, it is understandable that a wiper assembly (not shown in the figure) is usually provided on the front side of the first visible area 101. During operation, the wiper assembly cleans the front side of the first visible area 101 repeatedly. Due to the different radii of curvature, the amount of interference of the wiper assembly will be different. The third visible area 103 is spaced apart from the first visible area 101 to avoid the wiper assembly not cleaning properly and affecting the driver's vision.
[0076] Continue to refer to Figure 1 As shown, the first visible area 101 is the main field of vision of the driver and passengers. In some possible implementations, the first visible area 101 has a driver's field of vision area 1011 and a passenger's field of vision area 1012. The specific shapes of the driver's field of vision area 1011 and the passenger's field of vision area 1012 are not limited in this application embodiment.
[0077] In one possible implementation, the windshield body 100 also has a mounting area 104 through which the windshield body 100 can be mounted to the vehicle 20.
[0078] The first visible area 101, the second visible area 102 and the third visible area 103 are all located within the installation area 104, and the third visible area 103 is smoothly connected to the installation area 104.
[0079] The third visible area 103 is smoothly connected to the mounting area 104, avoiding the stress concentration problem caused by abrupt changes in curvature in traditional glass. This enhances the overall structural strength of the windshield and reduces the risk of cracks caused by vibration or external impact. It also prevents dents caused by excessively uneven appearance, ensuring the overall shape of the glass surface remains consistent. The first visible area 101, the second visible area 102, and the third visible area 103 are all located within the mounting area 104 and can be achieved through a unified mold forming process, reducing the complex steps of separate processing and lowering manufacturing costs.
[0080] The windshield body 100 can be installed onto the vehicle 20 via the mounting area 104. Specifically, the windshield body 100 can be installed onto the vehicle 20 via a mounting assembly. In this case, the mounting assembly can clamp and fix the mounting area 104 to avoid interference with the first visible area 101, the second visible area 102, and the third visible area 103, while improving the installation stability of the windshield body 100.
[0081] At least one outer edge of the third visible area 103 is collinear with the outer edge of the mounting area 104. For example Figure 1As shown, the top edge of the third visible area 103 is collinear with the top edge of the mounting area 104. The edge of the mounting area 104 can be directly used as a forming reference, eliminating the need for additional processing steps and improving production efficiency and yield. Furthermore, the length of the smooth connection between the third visible area 103 and the mounting area 104 can be reduced. For example, if the outer edge of the third visible area 103 is rectangular and its top edge is collinear with the mounting area 104, then when processing the smooth connection between the third visible area 103 and the mounting area 104, only the other three outer edges of the third visible area 103 need to be processed, further simplifying the structure, reducing manufacturing difficulty, and improving yield.
[0082] In one possible implementation, the windshield body 100 includes a first glass 110 and a second glass 120, the first glass 110 and the second glass 120 are bonded together, and the first glass 110 is located in front of the second glass 120.
[0083] The windshield is divided into two independently bonded layers: a first glass 110 and a second glass 120. The first glass 110 and the second glass 120 can be formed separately by a mold and then bonded together using a PVB film 10. The second glass 120 can provide stable support for the first glass 110, which significantly simplifies the manufacturing process.
[0084] The first visible area 101 and the second visible area 102 are located within the first glass 110. This simplifies the manufacturing process and increases the yield rate, as only the first glass 110 needs to be designed and molded.
[0085] This application also provides a vehicle 20, including a vehicle body and the aforementioned windshield assembly 30, which is disposed on the front side of the vehicle body. The windshield assembly 30 has been described in detail above and will not be repeated here. This vehicle 20 achieves the technical effects of the aforementioned windshield assembly 30, namely, it simplifies the structure of the windshield, reduces the phase deviation angle of the windshield, and improves the accuracy of data collected by the camera. In this application embodiment, the vehicle 20 can be a gasoline-powered vehicle, a natural gas-powered vehicle, or a new energy vehicle, and the new energy vehicle can be a pure electric vehicle, a hybrid electric vehicle, or a range-extended electric vehicle, etc. This application embodiment does not limit the specific structure of the vehicle 20.
[0086] In this application embodiment, vehicle 20 can also refer to large vehicles, small vehicles, special-purpose vehicles, etc. For example, according to vehicle type, vehicle 20 in this application embodiment can be a sedan, an off-road vehicle, a multi-purpose vehicle (MPV), or other types of vehicles. Of course, it can also be other types of vehicles 20, and this application embodiment does not limit this.
[0087] The implementation principle of a windshield assembly 30 and a vehicle 20 according to an embodiment of this application is as follows: The windshield assembly 30 includes a windshield body 100 and a camera assembly 200. The camera assembly 200 is located on the rear side of the windshield body 100. The windshield body 100 has a first visible area 101 and a second visible area 102; the first visible area 101 and the second visible area 102 are spaced apart; the camera assembly 200 can collect image data through the second visible area 102; the radius of curvature of the second visible area 102 is greater than the radius of curvature of the first visible area 101. Only the radius of curvature of the second visible area 102, i.e., the acquisition path of the camera assembly 200, is locally adjusted, rather than the entire radius of curvature of the windshield body 100, avoiding the complexity of adding a wedge-shaped PVB film 10 or significantly adjusting the glass structure in traditional solutions. Localized adjustment of the radius of curvature reduces processing difficulty, reduces manufacturing error risk, and improves yield. The radius of curvature of the second visible area 102 is greater than that of the first visible area 101. A larger radius of curvature results in a smoother glass surface curvature, leading to a smaller change in the refraction angle of light passing through it. This reduces the sub-phase deviation angle caused by surface refraction, effectively mitigating ghosting. Furthermore, by setting the first visible area 101 and the second visible area 102 alternately, conflicts with the acquisition path of the camera component 200 are avoided. This prevents global image deviations caused by global surface refraction in traditional solutions, directly improving the accuracy of the acquired data.
