Description

Technical Field

[0001] The present application relates to the technical field of automobile accessories, and in particular to a windshield assembly and an automobile. Background Art

[0002] In recent years, intelligent driving has gradually become a new development trend. It adds a sense of technology to cars, brings convenience to people's travel, and most importantly, can effectively avoid obstacles, make automatic avoidance in emergencies, and improve driving safety. In the field of intelligent driving, cameras, as an indispensable component, are responsible for tasks such as identifying vehicles, pedestrians, lane lines, red lights, and road signs.

[0003] With the development of intelligent driving, the requirements for camera image acquisition have also increased. Due to the defogger and frost requirements of the front windshield FOV (Field of view), heating wires are usually arranged in this area. When the camera is in a dark environment, the night light shines on the heating wire, which will produce edge diffraction stripes perpendicular to the direction of the heating wire. These stripes will interfere with the imaging quality of the camera, causing the intelligent driving algorithm to be unable to correctly identify and analyze, posing a safety hazard to the driver. Summary of the invention

[0010] Through this setting, the edge shape features of at least part of the anti-interference section in the imaging area become complex, making the interference of light more complex at the raised structure. The complex interference makes the originally regular diffraction stripes blurred, and the diffraction stripes show intensity changes and position shifts in local areas, which reduces the contrast of the diffraction stripes as a whole. From the perspective of imaging, the interference of such blurred and low-contrast diffraction stripes on camera imaging will be optimized to a certain extent.

[0012] Through this arrangement, it is ensured that most of the anti-interference sections have a continuously undulating non-straight edge shape feature, so that the camera assembly has a high imaging quality in most of the imaging area, and the imaging of the camera assembly is prevented from producing obvious edge diffraction stripes. In an optional embodiment, a plurality of the protruding structures are also arranged on the transition portion.

[0013] Through this setting, all anti-interference sections have continuously undulating non-straight edge shape features, so that the camera component has high imaging quality in the entire imaging area, fully improving the accuracy and safety of the car during intelligent driving and enhancing the user experience.

[0014] In an optional embodiment, the plurality of protruding structures have the same shape and size, so that the edge of at least a portion of the anti-interference section is periodically undulating.

[0015] Through this arrangement, the periodic high-frequency geometric mutations formed by multiple protruding structures are utilized to disperse the diffracted light energy, making the interference of light more complicated, reducing the contrast of the diffraction fringes, and reducing the impact on the imaging of the camera component.

[0016] In an optional embodiment, the protruding structure is triangular, arc-shaped or rectangular.

[0017] In an optional embodiment, the plurality of protrusion structures are arranged on opposite sides of the anti-interference section in its width direction.

[0018] Through this setting, the coherence of light waves can be destroyed in both directions in the anti-interference section, making the energy distribution of diffracted light more uniform, significantly reducing the overall diffraction fringe contrast, and being suitable for multi-angle light incident scenarios with stronger applicability.

[0019] In an optional embodiment, the width of the anti-interference section is less than or equal to 1.5 mm.

[0020] Through this arrangement, it is possible to improve the imaging quality of the camera assembly while avoiding excessive obstruction of the field of view of the camera assembly, thereby ensuring that the camera assembly can capture complete images without being disturbed by the shape of the heating wire itself.

[0042] In order to make the technical solutions and advantages of the present application more clear, the implementation methods of the present application will be further described in detail below with reference to the accompanying drawings.

[0043] In recent years, intelligent driving has gradually become a new development trend. It adds a sense of technology to cars, brings convenience to people's travel, and most importantly, can effectively avoid obstacles, make automatic avoidance in emergencies, and improve driving safety. In the field of intelligent driving, cameras, as an indispensable component, are responsible for tasks such as identifying vehicles, pedestrians, lane lines, red lights, and road signs.

[0044] With the development of intelligent driving, the requirements for camera image acquisition have also increased. Due to the defogger and frost requirements of the front windshield FOV (Field of view), heating wires are usually arranged in this area. When the camera is in a dark environment, the night light shines on the heating wire, which will produce edge diffraction stripes perpendicular to the direction of the heating wire at the edge of the heating wire. These stripes will interfere with the imaging quality of the camera, causing the intelligent driving algorithm to be unable to correctly identify and analyze, posing a safety hazard to the driver. For example, safety hazards include but are not limited to the following:

[0045] (1) In the images collected by the camera, the lights of the forward-facing vehicle are "drawn" (i.e., edge diffraction), which makes it easy to miss the target when there is a pedestrian crossing the diagonal front, resulting in a collision with the pedestrian;

[0046] (2) In the images collected by the camera, the vehicle lights are "drawn" and cover the traffic lights in front, causing the red and yellow lights to be discolored and detection errors, causing the car to brake incorrectly during intelligent driving;

[0047] (3) In the images captured by the camera, the “brushed” glare caused traffic lights to be mistaken for street lights, causing the car to cross the line and brake during intelligent driving;

[0048] (4) At night, the camera's vehicle detection accuracy decreases.

[0049] In order to solve the above technical problems, the present application provides a windshield assembly for use in vehicles such as automobiles.

[0050] like Figure 1 and Figure 2 As shown, the windshield assembly provided in the present application includes a windshield body 1 , a camera assembly 2 and a heating wire 3 .

[0051] The windshield body 1 has a viewing area 11 .

[0052] like Figure 1 As shown, the windshield body 1 also has an invisible area 12, which is printed with glass ink and is an opaque area used to shield components inside the vehicle.

[0053] The invisible area 12 surrounds the visible area 11, and the visible area 11 is a transparent area to ensure that the vision inside and outside the vehicle is not obstructed.

[0054] For example, the windshield body 1 is the front windshield of the car, located in the front of the car. Alternatively, the windshield body 1 can also be the rear windshield of the car, located in the rear of the car. The embodiment of the present application is described by taking the windshield body 1 as the front windshield of the car as an example.

[0055] The camera assembly 2 is installed on one side of the windshield body 1 , and an imaging area 23 of the camera assembly 2 is located within the visible area 11 .

[0056] Specifically, the camera assembly 2 is located on the side of the windshield body 1 close to the interior of the vehicle cabin. Figure 1 As shown, the camera assembly 2 includes a bracket 21 and a camera module 22 . The camera module 22 is mounted on the bracket 21 . The bracket 21 is fixed on the windshield body 1 . The lens of the camera module 22 faces the windshield body 1 .

[0057] It can be understood that the imaging area 23 of the camera assembly 2 is a virtual area where the area where the camera module 22 can capture images overlaps with the windshield body 1, such as Figure 1 As shown, the imaging area 23 of the camera assembly 2 is located inside the visible area 11 , and the size of the imaging area 23 is smaller than the size of the visible area 11 .

[0058] The heating wire 3 is continuously distributed on the windshield body 1, and at least part of the heating wire 3 is located in the visible area 11. The heating wire 3 has an anti-interference section 31, and the anti-interference section 31 is located in the imaging area 23. At least part of the anti-interference section 31 is provided with a plurality of continuously arranged raised structures 32, and the raised structures 32 are used to make the edge of at least part of the anti-interference section 31 continuously undulate.

[0059] Specifically, the heating wire 3 is used to connect to the on-board circuit of the car. The on-board circuit supplies power to the heating wire 3, which generates heat to heat up the windshield body 1, melting the frost, fog or ice attached to the surface, effectively preventing obstruction of vision, avoiding icing on the glass surface due to low temperature, reducing the risk of adhesion between the wiper and the glass, and ensuring driving safety.

[0060] like Figure 1 As shown, both ends of the heating wire 3 are provided with connection ends 33, and the connection ends 33 are used to be connected to the on-board circuit of the car.

[0061] For example, Figure 1 and Figure 2As shown, the heating wire 3 is continuously arranged on the windshield body 1, with a portion located in the non-visible area 12 and the other portion located in the visible area 11. The portion of the heating wire 3 located in the imaging area 23 of the camera assembly 2 constitutes an anti-interference section 31, and at least a portion of the anti-interference section 31 is provided with a plurality of continuously arranged convex structures 32, which can make the edge of the anti-interference section 31 where it is located continuously undulate and present a non-straight rough state.

[0062] Based on the edge effect of the heating wire 3 and according to the Huygens-Fresnel principle, the edge of the heating wire 3 can be regarded as a series of wavelet sources. When light is irradiated to the edge of the heating wire 3, these edge points will generate wavelets, which propagate to the surrounding space and interfere with each other to generate diffraction fringes.

[0063] By utilizing the raised structure 32, the edge shape features of at least part of the anti-interference section 31 in the imaging area 23 are made complex, making the interference of light more complex at the raised structure 32. The complex interference makes the originally regular diffraction stripes blurred, and the diffraction stripes show intensity changes and position shifts in local areas, which reduces the contrast of the diffraction stripes as a whole. From the perspective of imaging, the interference of such blurred and low-contrast diffraction stripes on camera imaging will be optimized to a certain extent.

[0064] Optionally, the heating wire 3 is located on the surface of the windshield body 1 close to the interior of the vehicle cabin, and can directly act on the fogging surface of the windshield body 1, directly heating the inner surface of the windshield body 1, quickly evaporating water vapor, and improving the defog efficiency, while preventing the heating wire 3 from being affected by factors such as rain and dust outside the car, resulting in resistance changes or circuit damage.

[0065] The windshield assembly provided in the embodiment of the present application has an anti-interference section 31 located in the imaging area 23 of the camera assembly 2, and at least a portion of the anti-interference section 31 is provided with a plurality of continuously arranged raised structures 32. Therefore, the edge of at least a portion of the anti-interference section 31 is non-straight and continuously undulates, making the interference of light more complex at the raised structure 32. The complex interference makes the originally regular diffraction stripes blurred, and the diffraction stripes have intensity changes and position shifts in local areas, which reduces the contrast of the diffraction stripes as a whole. From the perspective of imaging, the interference of such blurred and low-contrast diffraction stripes on the camera imaging will be optimized to a certain extent, thereby improving the imaging quality of the camera assembly 2, which is beneficial to improving the accuracy and safety of intelligent driving of automobiles.

[0066] In a further embodiment, the heating wire 3 is bent and distributed in a winding manner on the windshield body 1, and the anti-interference section 31 includes a plurality of main parts 311 and a plurality of transition parts 312, the plurality of main parts 311 extend along a first direction and are distributed at intervals from each other, the transition part 312 is used to connect two adjacent main parts 311, and an angle is formed between the transition part 312 and the main part 311, wherein the total length of the plurality of main parts 311 is greater than the total length of the plurality of transition parts 312, and a plurality of protrusion structures 32 are arranged on the main part 311.

[0067] like Figure 1 or Figure 2 As shown, the heating wire 3 is bent multiple times on the windshield body 1 to form a continuous winding shape similar to a snake or wave.

[0068] By setting the heating wire 3 to be bent, the coverage of the heating wire 3 on the surface of the windshield body 1 can be expanded, avoiding local overheating or cold areas caused by the straight heating wire structure, ensuring that heat is evenly diffused to the entire windshield body 1 area, and preventing residual dead corners during defrosting or defogging.

[0069] like Figure 1 As shown, the first direction is substantially horizontal, the length direction of the windshield body 1 is parallel to the first direction, the portion of the anti-interference section 31 extending along the first direction constitutes the main body 311 , and the remaining portion constitutes the transition portion 312 .

[0070] Exemplarily, two adjacent main body portions 311 are parallel to each other or located on the same extension line, and the transition portion 312 is used to connect the two adjacent parallel main body portions 311 , and the transition portion 312 is inclined to the main body portion 311 or perpendicular to the main body portion 311 .

[0071] The total length of the plurality of main bodies 311 is greater than the total length of the plurality of transitional parts 312. By providing the plurality of protruding structures 32 on the main body 311, it is possible to ensure that most of the anti-interference sections 31 have a continuously undulating non-straight edge shape feature, so that the camera assembly 2 has a high imaging quality in most of the imaging area 23, and avoids the generation of obvious edge diffraction fringes in the imaging of the camera assembly 2. In a further embodiment, the plurality of protruding structures 32 are also provided on the transitional part 312.

[0072] In this embodiment, the main body 311 and the transition part 312 are both provided with a plurality of protrusion structures 32. That is to say, all the anti-interference sections 31 have a non-straight edge shape feature with continuous undulations, so that the camera assembly 2 has a high imaging quality in the entire imaging area 23, fully improving the accuracy and safety of the car during intelligent driving and improving the user experience.

[0073] At the same time, this design is also conducive to improving the heating uniformity of the heating wire 3 in the imaging area 23, dispersing the thermal stress concentration, and ensuring that the heat in the imaging area 23 is evenly diffused.

[0074] In one embodiment, the plurality of protruding structures 32 have the same shape and size, so that the edge of at least a portion of the anti-tampering section 31 is periodically undulating.

[0075] Specifically, Figure 3 and Figure 4 As shown, each protruding structure 32 has the same shape and size, so that the edge of the anti-interference section 31 where it is located rises and falls continuously and regularly according to a specific period, and the distance between any two adjacent protruding structures 32 is equal.

[0076] Through this arrangement, the periodic high-frequency geometric mutations formed by the multiple protruding structures 32 are utilized to disperse the diffracted light energy, making the interference of light more complicated, reducing the contrast of the diffraction fringes, and reducing the impact on the imaging of the camera component 2.

[0077] In a further embodiment, the protruding structure 32 is in a triangular, arc-shaped, rectangular or trapezoidal shape.

[0078] For example, Figure 3 As shown, the protruding structure 32 is triangular in shape, so that at least part of the edge of the anti-tampering section 31 is serrated.

[0079] For example, Figure 4 As shown, the protruding structure 32 is arc-shaped, so that at least part of the edge of the anti-interference section 31 is wavy.

[0080] Exemplarily, the protruding structure 32 is rectangular (not shown in the figure), so that the edge of at least part of the anti-interference section 31 is square-shaped.

[0081] Exemplarily, the protruding structure 32 is trapezoidal (not shown in the figure), so that the edge of at least part of the anti-interference section 31 is trapezoidal corrugated.

[0082] It is understandable that the protrusion structure 32 may also be other regular or irregular shapes, which are not listed here one by one.

[0083] In one embodiment, a plurality of protrusion structures 32 are disposed on opposite sides of the anti-interference section 31 in its width direction.

[0084] Specifically, when the protrusion structure 32 is disposed on the main body 311, the plurality of protrusion structures 32 are located on both sides of the width direction of the main body 311. Similarly, when the protrusion structure 32 is disposed on the transition part 312, the plurality of protrusion structures 32 are located on both sides of the width direction of the transition part 312.

[0085] For example Figure 3 or Figure 4 As shown, the horizontal direction is the length direction of the anti-interference section 31 , and the vertical direction is the width direction of the anti-interference section 31 . Protruding structures 32 are provided on both sides of the width direction of the anti-interference section 31 .

[0086] By arranging multiple protruding structures 32 on opposite sides of the anti-interference section 31 in its own width direction, the coherence of light waves can be destroyed in both directions of the anti-interference section 31, making the diffraction light energy distribution more uniform, significantly reducing the overall diffraction fringe contrast, and being suitable for multi-angle light incident scenarios, with stronger applicability.

[0087] Optionally, the plurality of protruding structures 32 located on both sides of the anti-interference section 31 in the width direction may be symmetrically distributed with respect to the length direction of the anti-interference section 31 .

[0088] Alternatively, if Figure 3 or Figure 4 As shown, the multiple protrusion structures 32 located on both sides of the anti-interference section 31 in the width direction may also be staggered in the length direction of the anti-interference section 31 .

[0089] Based on any of the above embodiments, the width of the anti-interference section 31 is less than or equal to 1.5 mm, that is, the width of the heating wire 3 located in the imaging area 23 is less than or equal to 1.5 mm. Figure 3 As shown, the width of the interference protection section 31 is denoted by d.

[0090] By setting the width of the anti-interference section 31 to less than 1.5 mm, it is possible to improve the imaging quality of the camera component 2 while avoiding excessive obstruction of the field of view of the camera component 2, ensuring that the camera component 2 can capture complete images without being interfered by the shape of the heating wire 3 itself.

[0091] Optionally, the width of the anti-interference section 31 is also greater than or equal to 0.3 mm, that is, the width of the anti-interference section 31 is 0.3 mm to 1.5 mm.

[0092] By setting the width of the interference prevention section 31 to be greater than 0.3 mm, it is possible to avoid a reduction in mechanical strength and a shortened service life due to the interference prevention section 31 being too thin.

[0093] In one embodiment, the heating wire 3 is made of one or more of conductive silver paste, copper, and tungsten.

[0094] The conductive silver paste is a composite material formed by mixing silver and other compounds. The heating wire 3 made of the conductive silver paste has the advantages of high conductivity, low resistance, high temperature resistance, strong stability, etc.

[0095] In a further embodiment, the heating wire 3 is disposed on the windshield body 1 by a printing process.

[0096] Specifically, the conductive silver paste is printed onto the windshield body 1 using a screen printing process to form the heating wire 3. The process has strong adaptability and supports printing on glass substrates of different models. Through photosensitive platemaking technology, the pattern of the heating wire 3 can be accurately reproduced, and the edges of the printed lines are clear and uniform, taking into account both functionality and aesthetics. The production efficiency is high, and the heating wire 3 has strong adhesion and durability.

[0097] An embodiment of the present application also provides an automobile, comprising a windshield assembly provided by any of the above embodiments.

[0098] In the automobile provided in the embodiment of the present application, since the anti-interference section 31 is located in the imaging area 23 of the camera assembly 2, and at least part of the anti-interference section 31 is provided with a plurality of continuously arranged raised structures 32, the edge of at least part of the anti-interference section 31 is non-straight and continuously undulates, making the interference of light more complicated at the raised structure 32, and the complex interference makes the originally regular diffraction stripes blurred, and the diffraction stripes show intensity changes and position shifts in local areas, which reduces the contrast of the diffraction stripes as a whole. From the perspective of imaging, the interference of such blurred and low-contrast diffraction stripes on the camera imaging will be optimized to a certain extent, thereby improving the imaging quality of the camera assembly 2, which is beneficial to improving the accuracy and safety of the automobile's intelligent driving.
