[0002] This disclosure claims priority to a Chinese patent application filed with the China Patent Office on November 2, 2023, with application number 2023114496872 and titled “Window Assembly and Vehicle,” and the entire contents of the patent application are incorporated herein by reference. Technical Field

[0003] The present application relates to the technical field of vehicles, and in particular to a vehicle window assembly and a vehicle. Background Art

[0004] Laser radar, also known as LiDAR, is a sensor based on non-contact laser ranging technology. It consists of three major components: a transmitting system, a receiving system, and an information processing system. LiDAR is key sensing hardware for the implementation of Level 3 autonomous vehicles and above. With a detection range of up to 500 meters, LiDAR offers high measurement accuracy and is unrestricted by lighting conditions, significantly improving the reliability of autonomous driving systems.

[0005] In related technologies, LiDAR is generally installed externally on the roof. However, this external LiDAR solution has disadvantages such as large size and weight, susceptibility to adverse weather conditions such as rain and snow, impact from gravel, high wind resistance, and difficulty in anti-fogging and defrosting. Based on the above shortcomings, it has been proposed to build the LiDAR inside the vehicle, that is, to place the LiDAR inside the windshield. However, this solution has many technical difficulties, such as the weakening of the LiDAR's band signal penetration by the windshield structure, the realization of the anti-reflection function under large-angle incidence of specific wavelengths and the formulation of industrialization plans, and the installation of the built-in LiDAR. It is difficult to meet the actual requirements of signal transmission and reception, and the cost is relatively high.

[0027] To make the above-mentioned objects, features, and advantages of the present application more clearly understood, the specific embodiments of the present application are described in detail below with reference to the accompanying drawings. The following description sets forth many specific details to facilitate a full understanding of the present application. However, the present application can be implemented in many other ways than those described herein, and those skilled in the art can make similar improvements without violating the scope of the present application. Therefore, the present application is not limited to the specific embodiments disclosed below.

[0028] As described in the background art, there are many technical difficulties when the LiDAR is built into the car: such as the weakening of the LiDAR's band signal penetration by the windshield structure, the realization of the anti-reflection function under large-angle incidence of specific wavelengths and the formulation of industrialization plans, and the installation of the LiDAR when built in. It is difficult to meet the actual requirements of signal transmission and reception, and the cost is relatively high. The inventors have found that the reason for these problems is that after the LiDAR is built in, the signal transmittance of the LiDAR is affected by the loss of the windshield, so it is necessary to set an anti-reflection (AR) film in the projection area of ​​the LiDAR signal on the windshield to improve the signal transmittance. However, if the area of ​​the windshield where the AR film is set is too large, it will encroach on the main viewing area or the camera area, which will make installation difficult and greatly increase the coating cost.

[0029] Based on the above reasons, the present application provides a vehicle window assembly and a vehicle, which can meet the actual requirements of signal transmission and reception while reducing costs.

[0030] Referring to Figure 1 , a schematic diagram of the structure of a vehicle window assembly according to one embodiment of the present application is shown. The vehicle window assembly includes a vehicle window glass 10 and a laser radar 20. The vehicle window glass 10 is provided with an information collection area. The laser radar 20 is positioned on the side of the vehicle window glass 10 facing the interior of the vehicle, facing the vehicle window glass 10 and corresponding to the position of the information collection area. The housing 21 includes a front panel 211, which is parallel to the vehicle window glass 10.

[0031] It should be noted that "parallel" does not mean strictly parallel in the mathematical sense, but it means that it looks parallel to the naked eye, and a deviation of less than 10° is allowed.

[0032] In this way, since the front panel 211 is parallel to the vehicle window glass 10, the distance between the housing 21 and the vehicle window glass 10 can be designed to be very small, so that the information collection area of ​​the vehicle window glass 10 is reduced, and the area of ​​the anti-reflection film 11 is correspondingly reduced, thereby reducing the coating cost and saving more space for other functional integrated devices, such as infrared cameras, millimeter-wave LiDAR and other auxiliary driving function devices, thereby greatly reducing the difficulty of assembly.

[0033] In one embodiment, an anti-reflection film 11 is provided in the information collection area of ​​the vehicle window glass 10 .

[0034] It should be noted that the antireflection film 11 mainly functions to reduce or eliminate reflected light from the optical surface of the vehicle window glass 10, thereby increasing the light transmittance of these components and reducing or eliminating the stray light of the system. For example, it includes multiple high refractive index layers and multiple low refractive index layers stacked together.

[0035] In some embodiments, the antireflection coating 11 is designed and coated according to the detection signal requirements of the laser radar 20. High and low refractive index layers are alternately stacked, i.e., a low refractive index layer is stacked between every two adjacent high refractive index layers, and a high refractive index layer is stacked between every two adjacent low refractive index layers. The signal source of the laser radar 20 is any single wavelength between 800nm ​​and 1600nm. The commonly used wavelength is generally set to 905nm, 1550nm, or other arbitrary values ​​depending on the different laser radars 20.

[0036] When the detection signal of the laser radar 20 passes through the vehicle window glass 10 located in front of the laser radar 20, the vehicle window glass 10 will cause a certain degree of loss of the detection signal of the laser radar 20. As a comparative example, when there is no vehicle window glass 10 in front of the laser radar 20, the ranging capability of the laser radar 20 (10% reflection target) is 150m to 250m. When there is vehicle window glass 10 in front of the laser radar 20, due to the anti-reflection coating 11 on the vehicle window glass 10, the ranging capability of the laser radar 20 (10% reflection target) can still reach more than 150m.

[0037] In one embodiment, a vehicle window glass 10 includes a first light-transmitting plate, an adhesive layer, and a second light-transmitting plate laminated and connected in sequence. The first light-transmitting plate has a first surface and a second surface disposed opposite each other, and the second light-transmitting plate has a third surface and a fourth surface disposed opposite each other. The first surface faces the exterior of the vehicle, and the fourth surface faces the interior of the vehicle; the second surface and the third surface are disposed opposite each other. An antireflection film 11 is disposed on the first surface, the second surface, the third surface, or the fourth surface. Preferably, the antireflection film 11 is disposed on the fourth surface.

[0038] Optionally, the adhesive layer is configured as a coating or film layer, and specifically, may be a transparent film having sound insulation or heat insulation or both, and is used to bond and fix the first light-transmitting plate and the second light-transmitting plate, and the thickness is, for example, 0.38 mm to 0.76 mm. The adhesive layer may be made of polyvinyl butyral (PVB), polycarbonate (PC), sound insulation PVB, light-shielding tape PVB, heat-control PVB, ethylene vinyl acetate (EVA), thermoplastic polyurethane (TPU), ionomer, thermoplastic material, polybutylene terephthalate (PBT), polyethylene vinyl acetate (PET), polyethylene naphthalate (PEN), polyvinyl chloride (PVC), polyvinyl fluoride (PVF), polyacrylate (PA), polymethyl methacrylate (PMMA), polyurethane (PUR), and combinations thereof.

[0039] In one embodiment, referring to FIG. 1 , the distance X between the front panel 211 and the vehicle window glass 10 is set to be 1 mm to 5 mm. Specifically, X can be, for example, 1 mm, 1.5 mm, 2 mm, 2.5 mm, 3 mm, 3.5 mm, 4 mm, 4.5 mm, 5 mm, or any other value less than 1 mm and greater than 5 mm depending on actual needs. Preferably, the distance X between the front panel 211 and the vehicle window glass 10 is 1 mm to 3 mm.

[0040] In one embodiment, the laser radar 20 further includes a transmitter and receiver 22 disposed within the housing 21. The center of the transmitter and receiver 22 is 30 mm to 75 mm away from the center of the front panel 211. The center of the transmitter and receiver 22 is 31 mm to 80 mm away from the vehicle window glass 10.

[0041] Please refer to Figure 1. In one embodiment, the housing 21 further includes a bottom panel 212. The front panel 211 is connected to the bottom panel 212 and is arranged at an angle. The bottom panel 212 is, for example, parallel to the horizontal plane, that is, it is usually installed horizontally. The angle formed by the front panel 211 and the bottom panel 212 is r, and the angle r is the same as the installation angle θ of the vehicle window glass 10. Compared with the vertical arrangement of the front panel 211 and the bottom panel 212 in the related art (for example, as shown in Figure 3), the laser radar 20 in this embodiment can greatly reduce the distance between the front panel 211 and the vehicle window glass 10 when installed.

[0042] In one embodiment, the transmitter and receiver 22 (Sensor) of the laser radar 20 includes but is not limited to being located at the center of the shell of the laser radar 20.

[0043] In one embodiment, the horizontal FOV of the laser radar 20 is set to [-α, α], and the vertical FOV is set to [-β, β]; wherein α is 45° to 75°, specifically, for example, 45°, 50°, 55°, 60°, 65°, 70°, 75°, etc. In addition, β is 8° to 15°, specifically, for example, 8°, 10°, 12°, 13°, and 15°.

[0044] Referring to FIG. 1 , in one embodiment, the area S of the projection area formed by the detection signal of the laser radar 20 on the surface of the vehicle window glass 10 satisfies the following calculation formula:

[0045] Area S = [(40+X)*tanα*2]*[(40+X)*tanβ*2]÷cos(90-θ), where * is the multiplication sign, θ is the installation angle of the vehicle window glass 10, that is, the angle between the vehicle window glass 10 and the horizontal plane, and X is the distance between the front panel 211 of the laser radar 20 and the vehicle window glass 10.

[0046] In some embodiments, the vehicle window glass 10 is, for example, a front windshield, and θ is set to, for example, 18° to 35° or adjusted and set to other values ​​according to actual needs.

[0047] In the above-mentioned window assembly, the detection signal of the laser radar 20 forms a projection area S on the surface of the window glass 10 with an area of ​​3500mm 2 Up to 10000mm 2The area S is small enough, so that there is enough space to set the anti-reflection film 11 on the vehicle window glass 10 to meet the actual requirements of signal transmission and reception, and the area of ​​the anti-reflection film 11 set on the vehicle window glass 10 is small, which can prevent the anti-reflection film 11 from encroaching on the main viewing area or the camera area, making installation easier and reducing the coating cost.

[0048] In some embodiments, the area S includes but is not limited to 3500 mm 2 , 4000mm 2 , 4500mm 2 , 5000mm 2 , 5500mm 2 , 5800mm 2 , 6000mm 2 、6500mm 2 , 7000mm 2 , 7500mm 2 , 8000mm 2 , 8500mm 2 , 9000mm 2 , 9500mm 2 , 10000mm 2 The value can be adjusted and set flexibly according to actual needs.

[0049] In one embodiment, under the premise of the same FOV angle, the laser radar 20 of this embodiment has a relatively smaller projection area S on the window glass 10. After simulation calculation, when the horizontal distance X is set to 1mm and the mounting angle θ is 30°, the projection area S is 5000mm. 2 It is about one-third of the projection area of ​​the laser radar 20 in the related art (for example, as shown in FIG3 ) on the window glass 10 , which greatly reduces the projection area S, and also greatly reduces the area of ​​the information collection area.

[0050] In some embodiments, the shape of the antireflection film 11 includes but is not limited to regular shapes such as trapezoid, rectangle, circle, ellipse, or other irregular shapes, and can be flexibly adjusted and set according to actual needs.

[0051] In one embodiment, the antireflection film 11 is trapezoidal in shape, with the top edge of the antireflection film 11 being 2 cm to 10 cm long, the bottom edge of the antireflection film 11 being 7 cm to 26 cm long, and the distance between the top and bottom edges of the antireflection film 11 being 4 cm to 11 cm. Thus, the size of the antireflection film 11 is reasonably designed. On the one hand, the design size of the antireflection film 11 is large enough to completely cover the information collection area to meet the actual requirements of signal transmission and reception; on the other hand, the design size of the antireflection film 11 is not too large, thereby increasing the coating cost.

[0052] In some embodiments, the top length of the antireflection film 11 is, for example, 2 cm, 5 cm, 7 cm, or 10 cm. Furthermore, the bottom length of the antireflection film 11 is greater than the top length of the antireflection film 11, and is, for example, 7 cm, 10 cm, 15 cm, 20 cm, or 26 cm. Furthermore, the distance between the top and bottom of the antireflection film 11, i.e., the height of the trapezoid, is, for example, 4 cm, 6 cm, 8 cm, 10 cm, or 11 cm.

[0053] Referring to FIG. 1 , in one embodiment, the width of the housing 21 of the laser radar 20 is set to W, the depth of the housing 21 is set to D, and the height of the housing 21 is set to H. W is 100 mm to 200 mm, and specifically, for example, 100 mm, 130 mm, 140 mm, 160 mm, 170 mm, 200 mm, or any value other than 100 mm to 200 mm. D is 60 mm to 150 mm, and specifically, for example, 60 mm, 80 mm, 100 mm, 120 mm, 140 mm, 150 mm, or any value other than 60 mm to 150 mm. H is 15 mm to 50 mm, and specifically, for example, 15 mm, 20 mm, 35 mm, 40 mm, 45 mm, 50 mm, or any value other than 15 mm to 50 mm.

[0054] In one specific embodiment, W is 120mm to 150mm, D is 80mm to 120mm, and H is 25mm to 40mm. As can be seen, when designing the housing 21 of the laser radar 20, the depth D is made relatively small, while the width W can be relatively large. This reduces the depth extension of the laser radar 20, thereby reducing the encroachment on the vehicle's cockpit space. The extension of the width dimension W can compensate for the reduction in depth dimension in terms of volume, thereby meeting the space requirements of the internal components of the laser radar 20.

[0055] In some embodiments, the laser radar 20 is configured as an automotive-grade laser radar, and the product level and performance are high.

[0056] In some embodiments, the laser radar 20 has multiple forms, such as a semi-solid laser radar, a pure solid-state laser radar, and a mechanical laser radar.

[0057] Mechanical LiDAR was the first type of LiDAR to be used in autonomous driving. Its characteristic is that the laser generator is vertically arranged and can rotate 360°, allowing it to comprehensively scan the surrounding environment. Mechanical LiDAR can perform 3D scanning through physical rotation, providing comprehensive coverage of the surrounding environment and forming a point cloud. A point cloud is a dataset of spatial points generated by the LiDAR scan. Each point includes three-dimensional coordinate information (X, Y, Z) and laser reflection intensity, which is used to create a 3D map. However, the high-frequency rotation and complex mechanical structure result in an average failure time of only 1,000-3,000 hours, which is difficult to meet the minimum 13,000-hour requirement for automotive-grade equipment. Furthermore, mechanical LiDARs must be placed at the highest point of the vehicle body to avoid obstruction, significantly affecting the vehicle's styling. The protruding LiDAR is also susceptible to damage. Placing the LiDAR and other equipment and reinforcements on the roof can also affect the vehicle's center of gravity. Furthermore, the complex structure of mechanical LiDARs leads to high costs.

[0058] Referring to Figure 1 , in one embodiment, the laser radar 20 is a semi-solid-state laser radar. As such, a semi-solid-state laser radar is a compromise between a pure solid-state laser radar and a mechanical laser radar. Compared to a mechanical laser radar, a semi-solid-state laser radar only scans a certain angle in front of it. Compared to a pure solid-state laser radar, a semi-solid-state laser radar also has smaller moving parts. Furthermore, semi-solid-state laser radars are more easily controlled in terms of cost and size, making them more suitable for autonomous vehicles within the current technological and industrial context.

[0059] In one embodiment, a semi-solid-state laser radar, also known as a hybrid laser radar or a quasi-state laser radar, has multiple solutions, including but not limited to laser radar 20 products in various implementation forms such as MEMS galvanometers, rotating mirrors, and edges.

[0060] In some embodiments, the resolution of the laser radar 20 is between 0.1°*0.1° and 0.2°*0.2°.

[0061] In some embodiments, the weight of the laser radar 20 is set to 350g to 600g, preferably 350g to 450g.

[0062] In some embodiments, the operating power of the laser radar 20 is between 10W and 12W.

[0063] Embodiment and comparative example: A vehicle window assembly of the structure shown in FIG1 is compared and analyzed with a vehicle window assembly in the related art shown in FIG3 . Taking a semi-solid laser radar 20 as an example, the product specifications are 130 mm (width W) * 80 mm (depth D) * 35 mm (height H), and the transmitter and receiver 22 are located at the center of the housing 21. The field of view of the laser radar 20 is as follows: horizontal field of view angle α: ±60°, vertical field of view angle β: ±12°. Projected area S = [(40+x)*tan60°*2]*[(40+x)*tan12°*2]÷cos(90°-θ), and the following table is obtained:

[0064] Table 1

[0065] Table 2

[0066] By analyzing the above table, it can be clearly seen that the area S of the projection area formed by the detection signal of the laser radar 20 of this embodiment on the surface of the window glass 10 is 3500mm 2 Up to 10000mm 2 , the area S is small enough; when θ is the same, the larger the distance X is, the larger the projected area S is.

[0067] The area S of the projection area formed by the detection signal of the laser radar 20 in the comparative example on the surface of the window glass 10 is greater than 10000mm 2 .

[0068] Please refer to Figure 2, which shows a schematic structural diagram of a vehicle window assembly according to another embodiment of the present application. In one embodiment, the housing 21 of the laser radar 20 has an opening on the side facing the vehicle window glass 10 and is sealed against the vehicle window glass 10. The portion of the vehicle window glass 10 that seals the opening of the laser radar 20 is the front panel 211. This allows the laser radar 20's transmitter and receiver to be positioned relatively closer to the vehicle window glass 10, making the projected area S smaller and easier to adjust. Furthermore, the housing 21 in this embodiment has high waterproof, dustproof, soundproof, and heat-dissipating properties, better protecting the laser radar 20's core components from the vehicle's interior environment and dust, thereby increasing the laser radar 20's service life. Furthermore, it reduces attenuation of the laser radar 20's detection signal due to absorption, reflection, and other factors, thereby further increasing the laser radar 20's detection range, further reducing the product cost, and achieving a certain weight reduction effect.

[0069] In one embodiment, a vehicle includes the window assembly according to any one of the above embodiments.

[0070] In the above-mentioned vehicle, since the front panel 211 is parallel to the window glass 10, the distance X between the housing 21 and the window glass 10 can be designed to be very small, for example, the distance X is designed to be 1 mm-5 mm, so that the area of ​​the information collection area of ​​the window glass 10 is reduced, and the area of ​​the anti-reflection film 11 is correspondingly reduced, thereby reducing the coating cost and saving more space for other functional integrated devices, such as infrared cameras, millimeter-wave LiDAR and other auxiliary driving function devices, thereby greatly reducing the assembly difficulty.

[0071] In this application, unless otherwise specified or limited, the terms "mounted," "connected," "connected," "fixed," etc., should be interpreted broadly. For example, these terms may refer to fixed connections, removable connections, or integration; mechanical connections or electrical connections; direct connections or indirect connections through an intermediary; and internal communication between two components or interaction between two components, unless otherwise specified. Those skilled in the art will understand the specific meanings of these terms in this application based on the specific circumstances.

[0072] In this application, unless otherwise expressly specified or limited, if a first feature is described as being "above" or "below" a second feature, or similar descriptions, this may mean that the first and second features are in direct contact, or that the first and second features are in indirect contact through an intermediate medium. Furthermore, when a first feature is described as being "above," "above," or "above" a second feature, it may mean that the first feature is directly above or diagonally above the second feature, or simply means that the first feature is at a higher level than the second feature. When a first feature is described as being "below," "below," or "below" a second feature, it may mean that the first feature is directly below or diagonally below the second feature, or simply means that the first feature is at a lower level than the second feature.

[0073] The technical features of the above-mentioned embodiments can be combined arbitrarily. In order to make the description concise, not all possible combinations of the technical features in the above-mentioned embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0074] The above-described embodiments merely represent several implementation methods of the present application. While the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that a person of ordinary skill in the art may make various modifications and improvements without departing from the spirit of the present application, and these modifications and improvements fall within the scope of protection of the present application. Therefore, the scope of protection of the present patent application shall be determined by the appended claims.
