Description

Technical Field

[0001] This invention belongs to the field of vehicle camera technology, and relates to a vehicle camera mounting device, a rear corner window assembly, and a vehicle. Background Technology

[0002] Currently, vehicle side-view cameras are typically located on the exterior of the vehicle, such as fenders or side mirrors. Taking the fender as an example, an mounting opening needs to be made on the fender, and a decorative element and camera bracket need to be installed. The camera captures side and front side images through a window on the decorative element.

[0003] However, this arrangement has the following drawbacks: First, the camera is directly exposed to harsh environments such as wind, rain, mud, sand, and gravel, making the lens prone to getting dirty, which leads to a decrease in image quality or even failure, affecting driving safety; second, the fender is positioned low and is obstructed by the vehicle body, resulting in a limited field of vision and a large blind spot, making it difficult to meet the needs of advanced intelligent driving for panoramic perception; third, the installation structure is complex, with many parts and complicated assembly, and when multiple cameras are integrated, appearance problems such as gap differences and mismatch are more likely to occur.

[0012] Optionally, the mounting end of the conical body is provided with a limiting sleeve, the mounting port passes through the limiting sleeve, and an elastic limiting layer that contacts the camera body is provided inside the limiting sleeve.

[0013] Optionally, a first positioning rib is provided on the outer periphery of the annular ring, and a second positioning rib and a third positioning rib are provided on opposite sides of the conical body; a first positioning piece, a second positioning piece, and a third positioning piece are provided on the fixed bracket and are respectively bolted to the end faces of the first positioning rib, the second positioning rib, and the third positioning rib.

[0014] Optionally, it also includes a gasket for detachably mounting between the end faces of the first positioning piece and the first positioning rib, between the end faces of the second positioning piece and the second positioning rib, and between the third positioning piece and the third positioning rib, wherein the total thickness of the gasket is adjustable.

[0015] Optionally, it also includes a calibration component, which includes a light spot marker located in the light-transmitting area, the light spot marker being used to provide an optical reference for the optical axis of the camera body.

Detailed Implementation

[0032] The technical solution of the present invention will be further described in detail below with reference to embodiments and accompanying drawings. The directional terms such as up, down, left, right, front, back, front, back, top, and bottom mentioned or possibly used in this specification are defined relative to the structures shown in the accompanying drawings. The terms "inner" and "outer" refer to directions toward or away from the geometric center of a specific component, respectively. These are relative concepts and may therefore vary depending on their location and usage. Therefore, these or other directional terms should not be interpreted as restrictive terms.

[0033] like Figure 1 As shown, this embodiment of the invention provides a vehicle-mounted camera mounting device, such as... Figure 1 As shown, it includes a glass assembly 1, a camera body 2, and a mounting bracket 3.

[0034] Glass assembly 1 is used for installation at the window of the rear corner window 5 of the vehicle. The rear corner window 5 refers to the frame with a window located at the rear of the vehicle's side panel, between the rear door and the tailgate. Glass assembly 1 is shaped to match the window outline of the rear corner window 5 and may be constructed using laminated glass. Figure 1 and Figure 2 As shown, the glass assembly 1 has a light-transmitting area 10 and a light-shielding area 11. The light-transmitting area 10 provides a window area for light to pass through the camera body 2, and its position and size correspond to the field of view (FOV) area of ​​the camera body 2. The light-shielding area 11 is located on the outer periphery of the light-transmitting area 10 and is used to shield the internal structure to prevent light from inside the vehicle or reflected light from internal components from entering the imaging channel 42 and interfering with camera imaging.

[0035] like Figure 1 As shown, the camera body 2 is an in-vehicle camera module, which integrates an image sensor (such as a CMOS sensor), a lens assembly, and an image processing chip. The camera body 2 is used to acquire environmental images in the front-side direction of the vehicle, providing visual perception data from the front-side to the intelligent driving system.

[0036] like Figure 1 As shown, the mounting bracket 3 is located on the inner side of the glass assembly 1 (i.e., the side facing the interior of the vehicle), and the camera body 2 is mounted on the mounting bracket 3. The mounting bracket 3 serves as an intermediate connector between the camera body 2 and the glass assembly 1, providing a stable mounting base for the camera body 2. The mounting bracket 3 can be fixedly connected to the glass assembly 1 by means of adhesive, snap-fit, or threaded connection.

[0037] The light-transmitting area 10 corresponds to the field of view of the camera body 2. The camera body 2 acquires environmental images in the direction of the vehicle's side front through the light-transmitting area 10. Specifically, the lens of the camera body 2 faces the light-transmitting area 10. Ambient light from the side front of the vehicle passes through the light-transmitting area 10 and enters the lens of the camera body 2. It is converted into an electrical signal by the image sensor, and then processed by the image processing chip to output image data that can be used by the intelligent driving system.

[0038] The vehicle-mounted camera mounting device provided in this embodiment of the invention places the camera body 2 inside the glass assembly 1 (i.e., inside the vehicle compartment), preventing it from being directly exposed to harsh external environments such as wind, rain, mud, sand, and gravel. This effectively keeps the lens clean, avoiding image quality degradation or functional failure due to dirt accumulation, ensuring the normal operation of the intelligent driving system under various weather conditions, and improving driving safety. Meanwhile, the rear corner window 5 is located behind the side panel of the vehicle body and is positioned higher. Compared to the lower mounting position on the fender, the viewing height of the camera body 2 is significantly increased, and the obstruction by the vehicle structure is greatly reduced, providing a wider field of view in the side and front direction, effectively reducing blind spots, and better meeting the requirements of advanced intelligent driving for the accuracy and range of panoramic perception. Furthermore, this device eliminates the need for a mounting structure on the fender and additional decorative parts; the camera body 2 is simply mounted inside the glass assembly 1 using a fixing bracket 3. This reduces the number of parts, simplifies the assembly process, and avoids appearance problems such as poor gap and surface mismatch that can easily occur with multiple parts in the fender design.

[0039] In one optional way, such as Figure 3 and Figure 4 As shown, the glass assembly 1 adopts a laminated glass structure, including a first clear glass layer 12, an intermediate layer 13, and a second clear glass layer 14 stacked together. The first clear glass layer 12 is the outer glass facing the outside of the vehicle, and the second clear glass layer 14 is the inner glass facing the inside of the vehicle. Both are clear glass with a light transmittance greater than 90% (also known as transparent float glass) to ensure good optical transmission performance. The intermediate layer 13 is sandwiched between the first clear glass layer 12 and the second clear glass layer 14.

[0040] A transparent PVB film is provided at the position of the intermediate layer 13 corresponding to the light-transmitting area 10. The PVB film is a polyvinyl butyral film, which has good optical transparency, adhesion and impact resistance. The use of a transparent PVB film in the light-transmitting area 10 can ensure that the area has high light transmittance and low haze, so that the camera body 2 can clearly capture images of the external environment without optical distortion or image blurring caused by the material of the intermediate layer 13.

[0041] An ink layer is provided at the position of the intermediate layer 13 corresponding to the light-shielding area 11. The ink layer is formed on the surface of the intermediate layer 13 facing the first clear glass layer 12 and / or the surface facing the second clear glass layer 14 by screen printing or inkjet printing, and is firmly bonded to the glass after high-temperature sintering. The ink layer forms a black edge 15 on the outer periphery of the light-transmitting area 10. The black edge 15 appears as a black opaque area on the outer surface of the glass assembly 1. The black edge 15 covers the internal structural components of the glass assembly 1, such as the fixing bracket 3 and the light shield 4, so that the internal components are not visible when viewed from outside the vehicle, ensuring the aesthetic appearance of the vehicle; at the same time, it absorbs stray light and prevents light from entering the imaging channel 42 from areas outside the light-transmitting area 10 and interfering with the camera imaging.

[0042] The first clear glass layer 12, the intermediate layer 13 (including a transparent PVB film and an ink layer), and the second clear glass layer 14 are integrally formed by a high-temperature and high-pressure lamination process to form a complete laminated glass assembly 1.

[0043] By setting a transparent PVB film in the light-transmitting area 10 and forming a black edge 15 by setting an ink layer in the light-shielding area 11, the optical performance of different areas of the glass assembly 1 is differentiated. The light-transmitting area 10 has high light transmittance and low haze, ensuring the clarity and accuracy of the camera image; the light-shielding area 11, through the black edge 15, conceals the internal structure, which not only improves the appearance quality but also effectively reduces stray light interference. At the same time, the sandwich structure of the clear glass and the PVB film has good impact resistance and safety. When the glass is impacted by external force, the PVB film can bind the fragments together, preventing the fragments from flying and injuring people.

[0044] In one alternative implementation, such as Figure 3 and Figure 4 As shown, a heating wire 16 is also provided in the middle layer 13 of the glass assembly 1. The heating wire 16 is a resistance heating element and can be made of metal resistance wire (such as tungsten wire, copper-nickel alloy wire, etc.). The heating wire 16 is arranged at least partially along the outer periphery of the light-transmitting area 10, that is, the heating wire 16 extends around the edge of the light-transmitting area 10 to form a ring-shaped or nearly ring-shaped heating circuit.

[0045] The heating wire 16 can also extend further into the light-transmitting area 10, distributed within the light-transmitting area 10 in a sparse grid or serpentine pattern. To ensure that the heating wire 16 does not obstruct the field of view of the camera body 2, the wire diameter of the heating wire 16 is preferably 0.05mm to 0.15mm, and the grid spacing or wiring spacing is at least 5 times the wire diameter, so that the heating wire 16 is invisible or only produces a negligible slight effect in the camera's image.

[0046] The heating wire 16 is connected to a wiring harness assembly 17 for connecting to the vehicle's power supply to power the heating wire 16. The wiring harness assembly 17 includes wires and connectors. One end of the wiring harness assembly 17 is electrically connected to the heating wire 16 (by soldering or crimping), and the other end is provided with a connector compatible with the vehicle's power system. When the vehicle's power supply supplies power to the heating wire 16, the heating wire 16 generates Joule heat due to the resistance effect. The heat is conducted through the intermediate layer 13 to the glass surface corresponding to the light-transmitting area 10, causing the temperature of that area to rise.

[0047] Furthermore, the wiring harness assembly 17 can be arranged along the inner wall of the sheet metal of the vehicle side panel and fixed to the body sheet metal 6 by clips. One end of the wiring harness assembly 17 is electrically connected to the heating wire 16 and the camera body 2, and the other end passes through the wiring hole of the vehicle side panel and connects to the vehicle's power system and data bus system. A protective sleeve can be provided between the wiring harness assembly 17 and the body sheet metal 6 to prevent the wiring harness from being worn by the edge of the sheet metal.

[0048] Heating wires 16 arranged around the periphery of the light-transmitting area 10 can actively heat the glass in the light-transmitting area 10 under cold or high-humidity conditions. When the inner surface of the glass assembly 1 fogs or frosts due to the temperature difference between the inside and outside, the heating wires 16 are energized and generate heat. The heat is conducted through the intermediate layer 13 to the glass surface of the light-transmitting area 10, raising the temperature of that area above the dew point, and the fog or frost is quickly eliminated. Compared with the existing technology of arranging heating wires 16 in the interlayer of the windshield glass, this solution integrates the heating wires 16 into the intermediate layer 13 of the rear corner window 5 and forms a single piece with the glass assembly 1. It does not require a separate external heating module, resulting in a more compact structure, a shorter heating path, less heat loss, and higher heating efficiency.

[0049] In one alternative implementation, such as Figure 1 As shown, the vehicle-mounted camera mounting device also includes a light shield 4 disposed inside the glass assembly 1. The light shield 4 is a hollow shell structure, which can be made of plastic (such as ABS, PC / ABS alloy, etc.) through injection molding. The light shield 4 includes a mounting end 40, a positioning end 41, and an imaging channel 42 passing through the positioning end 41. The mounting end 40 is located at the end of the light shield 4 away from the glass assembly 1 and is used to connect with the fixing bracket 3. The positioning end 41 is located at the end of the light shield 4 close to the glass assembly 1 and is used to position and cooperate with the glass assembly 1. The imaging channel 42 extends from the positioning end 41 to the mounting end 40, providing a channel for light to enter the camera body 2 from the light-transmitting area 10.

[0050] The mounting end 40 is connected to the fixed bracket 3. Specifically, the mounting end 40 can be fixedly connected to the fixed bracket 3 by means of snap-fit ​​connection, threaded connection, or screw connection. The positioning end 41 is fitted against the inner wall of the glass assembly 1. Specifically, the end face of the positioning end 41 is tightly fitted against the inner surface of the glass assembly 1, and the fit and seal can be achieved by adhesive or elastic compression. The imaging channel 42 faces the light-transmitting area 10, that is, the central axis of the imaging channel 42 is approximately coincident with or coaxial with the central normal of the light-transmitting area 10. The camera body 2 is at least partially located inside the imaging channel 42, that is, the lens end of the camera body 2 extends into the imaging channel 42, and its lens faces the light-transmitting area 10.

[0051] The imaging channel 42 of the light shield 4 provides a closed optical path for the camera body 2, effectively blocking stray light from inside the vehicle (such as dashboard light source, interior reflected light, etc.) from entering the camera lens, avoiding image quality degradation caused by stray light interference; moreover, the fitting arrangement of the positioning end 41 with the inner wall of the glass assembly 1 forms a sealed connection between the imaging channel 42 and the light-transmitting area 10, preventing dust and moisture from entering the imaging channel 42 and contaminating the camera lens.

[0052] In an optional embodiment, an matting layer 420 is provided on the inner wall of the imaging channel 42 of the light shield 4. The matting layer 420 can be formed on the inner wall surface of the imaging channel 42 by means of spraying, electroplating, or attachment, and the matting layer 420 is a surface treatment layer with low reflectivity and high absorptivity.

[0053] As an optional implementation, the matte layer 420 is a matte paint layer sprayed on the inner wall of the imaging channel 42. The matte paint is a black matte paint with a micro-rough structure on its surface, which can absorb incident light and form diffuse reflection, thereby greatly reducing specular reflection.

[0054] As another optional implementation, the matte layer 420 is a matte film layer attached to the inner wall of the imaging channel 42. The matte film is a black matte film and is adhered to the inner wall of the imaging channel 42 by adhesive. As yet another optional implementation, the matte layer 420 is a rough surface layer formed on the inner wall of the imaging channel 42 by electrochemical etching or sandblasting.

[0055] If light entering the imaging channel 42 from the light-transmitting area 10 shines on the inner wall surface, the matting layer 420 can eliminate it through absorption and diffuse scattering, thereby effectively suppressing stray light interference and ensuring the clarity and accuracy of the camera image. In an optional embodiment, the positioning end 41 of the light shield 4 has an annular outer periphery 410. The annular outer periphery 410 is an annular end face of the positioning end 41 facing the glass assembly 1, and this annular end face is fitted to the inner wall of the glass assembly 1. The inner edge of the annular outer periphery 410 (i.e., the inner edge of the annular end face) is aligned with the inner edge of the black edge 15 (i.e., the edge of the black edge 15 facing the light-transmitting area 10), or the annular outer periphery 410 is located inside the black edge 15 (i.e., the inner edge of the annular outer periphery 410 is located between the inner edge and the outer edge of the black edge 15, and the annular outer periphery 410 is completely blocked by the black edge 15 when viewed from outside the vehicle).

[0056] Specifically, when viewed from outside the vehicle, because the inner edge of the annular outer periphery 410 is aligned with or located inside the black edge 15, the positioning end 41 of the sun visor 4 will not be exposed from the light-transmitting area 10, ensuring a neat and aesthetically pleasing appearance. At the same time, the large contact area between the annular outer periphery 410 and the inner wall of the glass assembly 1 is beneficial for improving sealing and connection stability.

[0057] By aligning the inner edge of the annular outer periphery 410 with the inner edge of the black border 15, or by placing the annular outer periphery 410 within the black border 15, the structure of the sun visor 4 is completely obscured by the black border 15 when viewed from outside the vehicle. No internal structural components are exposed at the edge of the light-transmitting area 10, ensuring the overall aesthetic appearance of the vehicle. At the same time, the large-area fit of the annular outer periphery 410 improves the connection strength and sealing reliability between the sun visor 4 and the glass assembly 1.

[0058] In an optional embodiment, the light shield 4 includes a hollow conical body. The conical body is a hollow shell structure, and its radial dimension gradually increases from the mounting end 40 to the positioning end 41 (i.e., it is flared), and the whole is frustoconical or truncated cone-shaped. An imaging channel 42 is formed inside the hollow conical body.

[0059] The mounting end 40 of the conical body has a mounting port 400 for the camera body 2 to pass into the imaging channel 42. The mounting port 400 is a circular opening with an inner diameter slightly larger than the outer diameter of the camera body 2, so that the camera body 2 can pass into the imaging channel 42 through the mounting port 400.

[0060] The tapered body gradually widens from the mounting end 40 to the positioning end 41, matching the field of view (FOV) of the camera body 2. The larger the field of view of the camera body 2, the larger the light-transmitting aperture required on the side closer to the glass assembly 1. The tapered structure minimizes the volume of the light shield 4 while ensuring that the camera's field of view is not obstructed, thus saving installation space inside the rear corner window 5.

[0061] In an optional embodiment, an electromagnetic shielding cover is further provided on the exterior of the camera body 2. The electromagnetic shielding cover is a cylindrical structure made of conductive metal material, fitted onto the outer wall of the camera body 2, and connected to the fixing bracket 3. The electromagnetic shielding cover has an opening at the position corresponding to the lens of the camera body 2, the inner diameter of which is larger than the outer diameter of the lens to avoid obstructing the field of view. An insulating layer is provided between the inner wall of the electromagnetic shielding cover and the outer wall of the camera body 2 to prevent short circuits. The electromagnetic shielding cover is used to shield against electromagnetic interference from electronic devices inside the vehicle, ensuring the transmission quality of image signals.

[0062] Furthermore, a grounding terminal is provided at the bottom of the electromagnetic shielding cover. The grounding terminal is connected to the body sheet metal 6 via a grounding wire. One end of the grounding wire is fixedly connected to the grounding terminal with screws, and the other end is fixed to the body sheet metal 6 via a grounding terminal. The surface of the grounding point on the body sheet metal 6 is the exposed metal surface after the paint layer has been removed.

[0063] In one alternative implementation, such as Figure 1 As shown, a limiting sleeve 401 is provided at the mounting end 40 of the conical body. The limiting sleeve 401 is a cylindrical structure extending outward from the mounting end 40 (i.e., away from the glass assembly 1), and it can be integrally formed with the conical body. The mounting port 400 passes through the limiting sleeve 401, that is, the mounting port 400 extends from the end of the limiting sleeve 401 into the interior of the conical body.

[0064] An elastic limiting layer is provided inside the limiting sleeve 401, which contacts the camera body 2. The elastic limiting layer is a material layer with a certain elasticity and coefficient of friction, and can be made of materials such as rubber, silicone, or polyurethane elastomer. The elastic limiting layer can be configured as a ring structure, fitted onto the inner wall of the limiting sleeve 401; or it can be configured as multiple block-shaped structures distributed circumferentially. When the camera body 2 passes through the mounting port 400 and enters the imaging channel 42, the elastic limiting layer contacts the outer wall of the camera body 2.

[0065] The inclusion of the limiting sleeve 401 and the elastic limiting layer ensures a more stable and reliable installation of the camera body 2 within the imaging channel 42. The elastic limiting layer provides radial clamping and positioning for the camera body 2, and also provides axial anti-slip resistance through static friction with the outer wall of the camera body 2, preventing axial movement of the camera body 2 under vibration. Furthermore, the elastic limiting layer also acts as a vibration damping layer, effectively suppressing vibrations transmitted to the camera during vehicle movement and ensuring imaging stability.

[0066] In an optional embodiment, an annular groove is provided at the bottom of the annular outer periphery 410 (i.e., the side facing the inner wall of the glass assembly 1). The annular groove is an annular concave structure extending circumferentially along the annular outer periphery 410, and its cross-sectional shape can be rectangular, trapezoidal, semi-circular, or V-shaped. The annular groove and the inner wall of the glass assembly 1 enclose an annular space for adhesive. Positioning adhesive is filled between the annular groove and the inner wall of the glass assembly 1. The positioning adhesive is an adhesive with bonding and sealing functions, such as structural adhesive, silicone sealant, or polyurethane adhesive. The positioning adhesive filling the annular groove serves two purposes: firstly, it bonds and fixes the annular outer periphery 410 to the inner wall of the glass assembly 1; secondly, it forms a sealing layer between the two, preventing moisture or dust from entering the imaging channel 42 from the interface between the annular outer periphery 410 and the glass.

[0067] In the specific assembly process, the positioning adhesive can be applied to the annular groove of the outer circumference 410 first, and then the outer circumference 410 is pressed onto the inner wall of the glass assembly 1. Under pressure, the positioning adhesive fills the annular groove and comes into close contact with the inner wall of the glass. After curing, a strong bond and seal are formed.

[0068] The annular groove increases the contact area and mechanical locking effect between the positioning adhesive and the annular outer periphery 410, thereby improving the bonding strength. The annular groove provides a space for the positioning adhesive, preventing it from being squeezed out during the pressing process and contaminating the light-transmitting area 10. After curing, the positioning adhesive in the annular groove forms an annular sealing barrier, effectively blocking the path of moisture and dust from seeping into the imaging channel 42 from the edge of the annular outer periphery 410.

[0069] In one alternative implementation, such as Figure 5As shown, a first positioning rib 43 is provided on the annular outer periphery 410. The first positioning rib 43 is a rib-shaped structure protruding outward from the surface of the annular outer periphery 410, and its end face is a flat mounting surface. A second positioning rib 44 and a third positioning rib 45 are respectively provided on opposite sides of the conical body. The second positioning rib 44 and the third positioning rib 45 are also rib-shaped structures protruding outward from the outer wall of the conical body, and their end faces are flat mounting surfaces.

[0070] The first positioning rib 43, the second positioning rib 44, and the third positioning rib 45 are preferably arranged in a spatial triangular pattern to achieve precise spatial positioning of the light shield 4.

[0071] like Figure 6 As shown, the fixed bracket 3 is provided with a first positioning piece 30, a second positioning piece 31, and a third positioning piece 32. Each positioning piece is a sheet-like structure extending from the body of the fixed bracket 3, and its position and extension direction correspond to each positioning rib. The end face of the first positioning piece 30 is connected to the end face of the first positioning rib 43 by bolts 7, the end face of the second positioning piece 31 is connected to the end face of the second positioning rib 44 by bolts 7, and the end face of the third positioning piece 32 is connected to the end face of the third positioning rib 45 by bolts 7.

[0072] Specifically, such as Figures 5 to 7 As shown, each positioning rib has a threaded hole or through hole on its end face, and each positioning piece has a corresponding through hole or threaded hole. The bolt 7 passes through the through hole on the positioning piece and is screwed into the threaded hole on the end face of the positioning rib, or the bolt 7 passes through the through hole on the end face of the positioning rib and is screwed into the threaded hole on the positioning piece, thereby realizing the detachable fixed connection between the fixed bracket 3 and the light shield 4.

[0073] The first positioning rib 43, the second positioning rib 44, and the third positioning rib 45 are connected to the corresponding bolts 7 of the first positioning piece 30, the second positioning piece 31, and the third positioning piece 32, achieving three-point positioning and fixation between the fixed bracket 3 and the light shield 4. Three-point positioning precisely defines the spatial position and orientation of the light shield 4 relative to the fixed bracket 3, ensuring accurate alignment of the central axis of the imaging channel 42 with the central normal of the light-transmitting area 10. The bolt 7 connection method facilitates assembly and disassembly, which is beneficial for later maintenance and replacement. Simultaneously, the first positioning rib 43, the second positioning rib 44, and the third positioning rib 45 are distributed at different positions on the outer periphery 410 of the ring and on both sides of the conical body, resulting in a uniform distribution of the connection load and improving the strength and vibration resistance of the connection structure.

[0074] In an optional embodiment, the vehicle-mounted camera mounting device further includes gaskets disposed between the end faces of each positioning piece and its corresponding positioning rib. Specifically, the first gasket is disposed between the end faces of the first positioning piece 30 and the first positioning rib 43, the second gasket is disposed between the end faces of the second positioning piece 31 and the second positioning rib 44, and the third gasket is disposed between the end faces of the third positioning piece 32 and the third positioning rib 45. The gaskets are sheet-like structures and can be made of metal (such as steel or aluminum), plastic, or elastic materials.

[0075] The total thickness of the gasket is adjustable. As one optional implementation, the gasket is a group of gaskets composed of multiple sheet-like gaskets of different thicknesses. The total thickness can be adjusted by selecting individual sheets of different thicknesses or by combining multiple individual sheets. As another optional implementation, the gasket is an elastic compressible gasket. The amount of compression of the gasket is changed by adjusting the tightening torque of the bolt 7, thereby achieving adjustment of the equivalent thickness.

[0076] The adjustable thickness of the pad allows for fine-tuning of the position and orientation of the light shield 4 relative to the fixed bracket 3 in three spatial directions via the first positioning rib 43, the second positioning rib 44, and the third positioning rib 45, thereby precisely calibrating the correspondence between the optical axis direction of the camera body 2 and the light-transmitting area 10.

[0077] In an optional embodiment, the vehicle-mounted camera mounting device further includes a calibration component. The calibration component is used to calibrate the optical axis of the camera body 2 before it leaves the factory or during vehicle use, so that the optical axis of the camera body 2 is precisely aligned with the center normal of the light-transmitting area 10 of the glass assembly 1, thereby ensuring that the image quality captured by the camera body 2 is optimal and that the field of view range precisely corresponds to the light-transmitting area 10.

[0078] Specifically, the calibration component includes a light spot marker positioned at the geometric center of the light-transmitting area 10. This light spot marker serves as a visual reference point in the image captured by the camera body 2, acting as a benchmark for determining optical axis alignment. When the optical axis of the camera body 2 coincides with the central normal of the light-transmitting area 10, the light spot marker is located at the geometric center of the image. When the optical axis of the camera body 2 deflects or shifts relative to the central normal of the light-transmitting area 10, the light spot marker will deviate from its geometric center in the image. Therefore, the imaging position of the light spot marker can be used as a basis for determining optical axis alignment.

[0079] In an optional embodiment, the light spot mark is formed on the glass assembly 1. Specifically, the light spot mark is formed directly on the outer surface of the first clear glass layer 12 (the side facing outwards) or the inner surface of the second clear glass layer 14 (the inner surface of the interlayer) of the glass assembly 1 by laser etching, screen printing, or coating, located at the geometric center of the light-transmitting area 10. The light spot mark forms an integral structure with the glass assembly 1, maintaining its position throughout the entire service life of the vehicle without requiring additional installation or removal operations.

[0080] Furthermore, the light spot markers can be any one of crosshairs, dots, or concentric rings, with a line width or diameter ranging from 0.1mm to 0.5mm, to ensure that the light spot markers are clearly visible in the image captured by the camera body 2, while not obstructing or interfering with the normal field of view of the camera body 2. Preferably, the light spot markers are formed of a semi-transparent material, which has no significant impact on camera imaging under normal vehicle driving conditions, and can be made visible by adjusting the camera gain or supplemental lighting in calibration mode.

[0081] In another optional embodiment, the calibration assembly further includes a calibration light source module detachably mounted to the glass assembly 1. The calibration light source module is an independently detachable external device used to project light spot marks onto the inner surface of the glass assembly 1.

[0082] Specifically, the calibration light source module includes a housing, a light source, and a grating. The housing is a cylindrical or box-shaped structure used to house and protect the internal components. The light source is located inside the housing and is an LED or laser diode, preferably emitting light in the visible light band (such as red or green light) to facilitate clear identification by the camera body 2, while avoiding potential damage to the glass material or camera sensor caused by ultraviolet or infrared light. The grating is located in the light path of the light source and is engraved with crosshair or circular scale lines. The light emitted by the light source passes through the grating to form a projected beam with a specific pattern, creating clear light spot marks on the inner surface of the glass assembly 1.

[0083] The calibration light source module is detachably mounted on the outside of the glass assembly 1 (i.e., the outside of the vehicle). Specifically, the housing of the calibration light source module is provided with a mounting positioning structure, which includes at least two positioning pins and / or magnetic elements. The outer surface of the glass assembly 1 has pre-set mounting holes and / or magnetic adsorption components that mate with the mounting positioning structure on the outer side corresponding to the geometric center position of the light-transmitting area 10. The calibration light source module is detachably mounted on the outer surface of the glass assembly 1 through the insertion engagement of the positioning pins with the mounting holes or the adsorption engagement of the magnetic elements with the magnetic adsorption components. After installation, the emission axis of the calibration light source module (i.e., the projection axis of the light emitted by the light source after passing through the grating) precisely coincides with the central normal of the light-transmitting area 10, ensuring that the projected light spot mark is accurately located at the geometric center position of the light-transmitting area 10.

[0084] When the calibration light source module is installed on the outside of the glass assembly 1 and the light source is turned on, the light passes through the grating and projects a clear spot or crosshair onto the inner surface of the glass assembly 1. This spot or crosshair is located at the geometric center of the light-transmitting area 10. The camera body 2 determines whether there is a deviation in its own optical axis by acquiring the imaging position of this projected spot. After calibration, the calibration light source module can be removed from the outside of the glass assembly 1 without affecting the normal appearance and use of the vehicle.

[0085] The present invention also provides a rear corner window assembly, such as Figure 8 As shown, the device includes the vehicle-mounted camera mounting device described in any of the above embodiments and the rear corner window 5. The rear corner window 5 has a window frame structure with an outline that matches the opening of the side panel of the vehicle body, so as to facilitate installation on the body panel.

[0086] A positioning hole 50 is provided on the rear corner window 5. The positioning hole 50 is an opening that penetrates the rear corner window 5, and its shape and size match the shape and size of the glass assembly 1. The glass assembly 1 is installed in the positioning hole 50. Specifically, the outer peripheral edge of the glass assembly 1 is bonded and fixed to the inner peripheral edge of the positioning hole 50 with adhesive (such as polyurethane glass glue) to form a sealed connection. The light-transmitting area 10 of the glass assembly 1 corresponds to the central area of ​​the positioning hole 50, ensuring that the camera body 2 can acquire images of the external environment through the light-transmitting area 10.

[0087] The rear corner window 5 and the glass assembly 1 together constitute a complete rear corner window assembly. This assembly, as an independent modular component, can be installed as a whole at the rear corner window opening of the vehicle on the final assembly line. The assembly and calibration of the camera mounting device and the rear corner window 5 can be completed in advance on the production line, improving production efficiency and assembly quality. The rear corner window assembly is installed on the vehicle body as a whole module, simplifying the assembly process on the final assembly line and facilitating later maintenance and replacement. When the camera or glass assembly 1 malfunctions, the entire rear corner window assembly can be replaced, or the camera mounting device can be disassembled separately for repair.

[0088] The present invention also provides a vehicle, such as Figure 9 As shown, it includes the aforementioned rear corner window assembly and body sheet 6. Body sheet 6 is a sheet metal structure for the side of the vehicle and has a rear window opening. The rear corner window assembly is installed at the rear window opening of body sheet 6.

[0089] The vehicle provided in this embodiment of the invention achieves reliable installation of a side-front panoramic camera by installing the aforementioned rear corner window assembly at the rear window opening of the vehicle body sheet metal. The camera is positioned inside the passenger compartment, avoiding interference from the external environment and ensuring long-term stable image quality; the high-position installation of the rear corner window 5 provides a wider side-front field of view, effectively enhancing the perception capabilities of the intelligent driving system.

[0090] In one optional embodiment, the rear corner window assembly includes a soft edging and positioning posts injection-molded around the outer periphery of the glass assembly 1. Specifically, the glass assembly 1 is placed in an injection mold, and a soft material (such as thermoplastic elastomer TPE, EPDM, or PVC) is injection-molded to cover the outer periphery of the glass assembly 1, while simultaneously molding the positioning posts integrally. The soft edging, positioning posts, and glass assembly 1 are integrated into a single structure through injection molding, reducing the number of parts and simplifying the assembly process.

[0091] The soft edging extends continuously along the outer periphery of the glass assembly 1, forming an annular elastic sealing layer. When the rear corner window assembly is installed at the rear window opening, the soft edging elastically abuts against the periphery of the rear window opening, forming a sealing fit to prevent rainwater and dust from seeping into the vehicle interior through the gap between the glass assembly 1 and the body sheet metal 6.

[0092] The positioning pins are columnar structures protruding outward from the outer periphery of the glass assembly 1, and their positions and numbers correspond to the positioning openings on the body sheet metal 6. The rear corner window assembly is bonded to the body sheet metal 6 with glass glue (polyurethane adhesive), and the positioning pins are inserted into the positioning openings of the body sheet metal 6 to achieve precise positioning during installation.

[0093] In one alternative implementation, such as Figure 10 As shown, the aforementioned rear corner window assemblies are installed in the left and right rear window openings of the vehicle, respectively. That is, there is one rear corner window assembly on each of the left and right sides of the vehicle, and each rear corner window assembly integrates a vehicle-mounted camera mounting device.

[0094] The camera body 2, located within the left rear corner window assembly, faces the front left side of the vehicle. This camera captures an image of the environment in front of the left side of the vehicle through its left-side light-transmitting area 10, forming the left-side forward-viewing area. Similarly, the camera body 2, located within the right rear corner window assembly, faces the front right side of the vehicle. This camera captures an image of the environment in front of the right side of the vehicle through its right-side light-transmitting area 10, forming the right-side forward-viewing area.

[0095] The left and right forward-looking areas together provide the vehicle's intelligent driving system with lateral and forward-facing panoramic perception information. The fields of view of the two cameras can partially overlap directly in front of the vehicle to generate depth information through binocular vision; alternatively, they can each cover different angular ranges, together forming a complete lateral and forward-facing perception coverage.

[0096] Compared to solutions that only place cameras on one side or only on the fender, this solution can simultaneously acquire environmental images from both the left and right front directions of the vehicle, providing more comprehensive perception information for the intelligent driving system. The fields of view of the left and right cameras can complement each other, effectively eliminating blind spots on one side and improving the accuracy and reliability of the intelligent driving system's perception of the side and front environment. It is particularly suitable for driving scenarios that require side and front environmental perception, such as crossing intersections, lane change assistance, and automatic parking.

[0097] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this application, and are not intended to limit them. Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this application.
