[0056] The following is based on Figures 1 to 11 The present invention provides a detailed description of the window assembly.
[0057] In this embodiment, such as Figure 1 and Figure 9 As shown, the vehicle window assembly 100 includes a window glass 1 and a luminous warning sign 2. The luminous warning sign 2 is installed on one side of the surface of the window glass 1. Without manual placement, the vehicle can automatically warn pedestrians outside the vehicle via the luminous warning sign 2 on the window glass 1. Figure 2 , Figures 8 to 11 As shown, the luminous warning sign 2 includes a light-emitting component 21. When the light-emitting component 21 emits light, the luminous warning sign 2 forms at least a first light pattern 211 in the shape of a triangle. When the vehicle is in a preset mode, the light-emitting component 21 emits light, and the luminous warning sign 2 forms the first light pattern 211, actively turning on the light warning to enhance the warning effect. Furthermore, since the first light pattern 211 is triangular, the warning effect is more obvious.
[0058] The above technical solution involves installing a luminous warning sign 2 on one side of the vehicle window glass 1. This luminous warning sign 2 forms a triangular first light pattern 211, automatically providing a warning when the vehicle is in a preset mode. The vehicle can transmit warning light signals to the outside world in real time and effectively, improving driving safety through intelligent warnings. Compared to traditional triangular warning signs, this solution eliminates the need for manual placement of the triangular warning sign, transforming passive warnings into active warnings, and upgrading from simple warning signal transmission to active interactive warnings. It becomes one of the interfaces for interaction between the vehicle and the outside world, enriching the vehicle's indicator light functions. Furthermore, this solution directly installs the luminous warning sign 2 on one side of the vehicle window glass 1. Compared to installing the luminous warning sign 2 on the vehicle via a rotating connection or a lifting mechanism, this solution does not require modification of the vehicle's original structure, thus reducing manufacturing costs. The luminous warning sign 2 is always in the working position, and when a warning is needed, there is no need to wait to switch the luminous warning sign 2 to the working position (e.g., by rotating or lifting). It can provide an instant warning. Moreover, the luminous warning sign 2 does not need to be switched, which also helps to improve the stability of the luminous warning sign 2 in use, avoids malfunctions or damage caused by frequent position switching, and reduces the probability of maintenance.
[0059] It should be explained that the window assembly 100 can be applied to autonomous vehicles. Although the autonomous vehicle market is still developing and the current user base is relatively small, it has a promising future. Because autonomous vehicles are unmanned, safety during operation is paramount. The window assembly 100 in this solution can adapt to the needs of autonomous vehicle decision-making and vehicle-to-infrastructure (V2I) collaboration, thus improving driving safety. Of course, the window assembly 100 can also be applied to manned vehicles, including both ordinary and intelligent vehicles. It can adapt to the needs of autonomous vehicle decision-making, human-vehicle collaboration, and V2I collaboration, reducing human intervention and eliminating the need for manual intervention to place illuminated warning signs. It is more intelligent and can prevent collisions during the placement of the illuminated warning signs. Furthermore, if occupants are injured and unable to move easily, the illuminated warning sign 2 can provide timely and proactive warnings, preventing secondary accidents.
[0060] It should be explained that the vehicle window glass 1 can be the rear windshield, side window, or triangular window of the vehicle, among which, such as Figure 9 As shown, when the luminous warning sign 2 is installed on the rear windshield, it is used to warn vehicles approaching from behind; when it is installed on the side windows, it is used to warn vehicles approaching from the side; and when it is installed on the triangular window, it can be used to warn pedestrians to the side, in front, or to the side and behind. Of course, for specific warning needs, the application of the luminous warning sign 2 on the windshield or sunroof is also possible.
[0061] In one embodiment, the vehicle's preset modes include, but are not limited to, hazard light activation mode, normal driving mode, and emergency braking mode. For example, when the vehicle is in hazard light activation mode, the luminous warning sign 2 can flash at the same frequency as the hazard lights to enhance the warning effect; when the vehicle is in normal driving mode, the luminous warning sign 2 can remain constantly lit to serve as a vehicle position warning; when the vehicle brakes suddenly, the luminous warning sign 2 flashes to give a danger warning. The illumination mode can be customized according to needs to provide corresponding automatic warnings in different scenarios. Furthermore, the light display mode can be adjusted to provide more prompting functions, giving a single installation point a multi-port, multi-functional terminal integrating communication, interaction, and security. Further, to ensure an effective warning effect, when an incoming vehicle or person is 150 meters away from the vehicle window assembly 100, the incoming person should be able to clearly see the light warning of the luminous warning sign 2.
[0062] In one implementation, such as Figure 1 and Figure 8 As shown, the front of the luminous warning sign 2 abuts against the inner surface of the vehicle window glass 1. In this case, the front of the luminous warning sign 2 is the mounting surface. Thus, the luminous warning sign 2 is located inside the vehicle, and the vehicle body can provide dust and water protection for the luminous warning sign 2. It should be explained that "the front of the luminous warning sign 2" refers to the side of the luminous warning sign 2 with the warning surface 2151.
[0063] In another embodiment, the back of the luminous warning sign 2 abuts against the outer surface of the vehicle window glass 1. In this case, the back of the luminous warning sign 2 is the mounting surface. Thus, the luminous warning sign 2 is located on the exterior of the vehicle and does not occupy interior space. Of course, to prevent the luminous warning sign 2 from short-circuiting due to water ingress, a waterproof casing can be used to protect it. It should be explained that "the back of the luminous warning sign 2" refers to the side opposite to "the front of the luminous warning sign 2".
[0064] In one embodiment, the luminous warning sign 2 is bonded to the vehicle window glass 1 via an adhesive layer. The luminous warning sign 2 is easy to install and has low installation costs. For example, PU adhesive (polyurethane adhesive) can be used to bond the luminous warning sign 2 to the vehicle window glass 1, and the PU adhesive forms an adhesive layer after curing. Specifically, taking the bonding of the front of the luminous warning sign 2 to the inner surface of the vehicle window glass 1 as an example, when installing the luminous warning sign 2, adhesive is applied to the corresponding position on the front of the luminous warning sign 2, and then the front of the luminous warning sign 2 is pressed onto the vehicle window glass 1. After the adhesive cures, the luminous warning sign 2 is installed in place.
[0065] In one implementation, such as Figure 8As shown, the periphery of the luminous warning sign 2 is triangular. Specifically, since the periphery of the luminous warning sign 2 is triangular, and people are accustomed to triangles as a warning signal, the warning effect of triangles has high social acceptance, especially for danger warnings. Therefore, when the luminous warning sign 2 is illuminated by external lights in daylight or dark environments, people outside the vehicle can quickly and intuitively see the existence of the luminous warning sign 2, and the luminous warning sign 2 is not easily ignored.
[0066] In one implementation, such as Figure 9 As shown, when the window assembly 100 is installed on the vehicle body, the warning surface 2151 of the luminous warning sign 2 extends at an angle, that is, the warning surface 2151 forms an angle with the horizontal plane. Specifically, when installing the luminous warning sign 2, since the mounting surface of the luminous warning sign 2 abuts against one side surface of the window glass 1, and the window glass 1 is tilted, the luminous warning sign 2 is also tilted, and the warning surface 2151 extends approximately along the window glass 1 at an angle. It should be explained that "approximately" in "the warning surface 2151 of the luminous warning sign 2 extends approximately along the window glass 1 at an angle" means that when both the warning surface 2151 and the mounting surface of the luminous warning sign 2 have the same shape as the mounting surface of the window glass 1, for example, when all three are flat, the warning surface 2151 extends approximately along the window glass 1 at an angle. The warning surface 2151 can extend perfectly along the window glass 1 at an angle. The extension directions of the two can be exactly the same or there can be an allowable error. When the shape of the mounting surface of the warning surface 2151 and the window glass 1 is different, for example, when the mounting surface of the warning surface 2151 and the luminous warning sign 2 is flat and the mounting surface of the window glass 1 is curved, the warning surface 2151 cannot extend perfectly along the window glass 1 at an angle. However, since the curvature of the mounting surface of the window glass 1 is small, the warning surface 2151 can still extend as much as possible along the window glass 1 at an angle.
[0067] Because the illuminated warning sign 2 extends at an angle, in order to ensure that the illuminated warning sign 2 seen by people outside the vehicle is an equilateral triangle or has a shape error that is difficult to distinguish with the naked eye, this solution improves the peripheral contour of the illuminated warning sign 2 and the shape of the first light graphic 211, so that the shape of the illuminated warning sign 2 conforms to the standard for triangular warning signs for motor vehicles. Specifically, as follows... Figure 10 As shown, when viewed from a normal perspective, the peripheral outline of the luminous warning sign 2 has the same shape as the first light graphic 211, and both are non-equilateral isosceles triangles. The specific shape of the non-equilateral isosceles triangle is adjusted according to the tilt direction and angle of the vehicle window glass 1 on which the luminous warning sign 2 is applied. Here, "normal perspective" refers to the straight line direction perpendicular to the warning surface 2151 of the luminous warning sign 2. Figure 9 and Figure 11As shown, when viewing the window assembly 100 from the first direction, the peripheral outline of the luminous warning sign 2 has the same shape as the first light graphic 211, and both are equilateral triangles or approximately equilateral triangles. The first direction is the direction facing the side of the vehicle body with the window assembly 100. For example, when the window assembly 100 is the rear window of the vehicle, the first direction is the direction directly behind the rear window, that is, the direction parallel to the longitudinal axis of the vehicle, which can also be understood as the direction of the vehicle's straight-line movement. When the window assembly 100 is a side window of the vehicle… The first direction is the direction from the side of the vehicle facing the side of the vehicle body with the window assembly 100, that is, the direction perpendicular to the longitudinal axis of the vehicle and parallel to the road surface, which can also be understood as the direction perpendicular to the vehicle's direction of travel and parallel to the road surface; when the window assembly 100 is the windshield of the vehicle, the first direction is the direction directly in front of the windshield, that is, the direction parallel to the longitudinal axis of the vehicle, which can also be understood as the direction of the vehicle moving backward in a straight line; when the window assembly 100 is the sunroof of the vehicle, the first direction is the direction perpendicular to the road surface. It should be explained that... Figure 10 and Figure 11 Only the graphic of the light is shown; the peripheral outline of the luminous warning sign 2 is not shown. The shape of the peripheral outline of the luminous warning sign 2 is the same as the shape of the first light graphic 211.
[0068] It should be explained that due to differences in the position or height of people outside the vehicle, the angle at which different people observe the window assembly 100 will differ in practical applications. This can be mitigated by increasing the size of the luminous warning sign 2 to reduce the difference in the shape of the luminous warning sign 2 as observed by different people, making it difficult for the naked eye to discern the difference in the viewing angle of the luminous warning sign 2. That is, the shape of the periphery of the luminous warning sign 2 and the first light graphic 211 seen by people outside the vehicle is an equilateral triangle or nearly an equilateral triangle.
[0069] In one implementation, such as Figure 9 As shown, window 1 is the rear windshield of the vehicle. Specifically, during vehicle operation, most uncontrollable risks come from behind the vehicle, and when the vehicle needs to stop temporarily, it is also necessary to warn vehicles behind. Applying the luminous warning sign 2 to the rear windshield is more practical. In addition, for autonomous vehicles, applying the luminous warning sign 2 to the rear windshield can solve the problem that autonomous vehicles cannot directly use traditional triangular warning signs.
[0070] In one implementation, such as Figure 10 and Figure 11As shown, when the light-emitting component 21 emits light, the luminous warning sign 2 also forms at least a second light graphic 212, with the first light graphic 211 surrounding the second light graphic 212. Specifically, when the luminous warning sign 2 provides a light warning, the formation of at least a first light graphic 211 and a second light graphic 212 enhances the visual lighting effect and improves the light warning effect. Furthermore, the first light graphic 211 surrounds the second light graphic 212, making the first light graphic 211 more prominent and allowing observers to quickly perceive the triangular shape of the light, thus providing a rapid warning effect. Preferably, the first light graphic 211 and the second light graphic 212 have different shapes, resulting in a more prominent visual effect and improved light warning effect. Of course, the first light graphic 211 and the second light graphic 212 can also have the same shape but different sizes, so that the first light graphic 211 can surround the second light graphic 212.
[0071] Furthermore, such as Figure 10 and Figure 11 As shown, the second light graphic 212 is a light tunnel graphic, which enhances the visual impact by forming a series of light tunnels that change from bright to dark and extend infinitely into the distance.
[0072] Furthermore, the brightness of the outer ring of the light tunnel pattern is 550-650 nits, and the brightness of the inner ring is 250-350 nits. By increasing the brightness of the light from the inside out, the desired light tunnel pattern is formed.
[0073] In one implementation, such as Figure 2 and Figure 3 As shown, the light-emitting component 21 includes an LED chip plate 213, a reflective element 214, and a semi-transparent / semi-reflective element 215. The semi-transparent / semi-reflective element 215 is located on the reflected light path of the reflective element 214, and its exit surface serves as the warning surface 2151 of the luminous warning sign 2. The reflective element 214 has a reflectivity of 100% and can be made by electroplating a reflective layer onto a plastic part. The semi-transparent / semi-reflective element 215 has a transmission area and a reflection area, with multiple transmission and reflection areas. The reflective element 214 has a reflectivity of 50% and a transmittance of 50%. The LED chip plate 213 includes a plate body and multiple LED chips. The LED chips can be LED red light chips, which have a simple structure, reasonable cost, a wavelength of 610 nm - 660 nm, and a power of 0.2 W - 0.5 W.
[0074] When the LED chip plate 213 emits light, some of the light emitted from the LED chip plate 213 passes directly through the transmission area of the transmissive element 215 and is emitted directly along the original light path. This part of the light is seen by the observer, forming the first layer of light-emitting points. Additionally, some light is reflected by the reflection area of the transmissive element 215 to the reflection element 214, and then reflected by the reflection element 214 back to the transmissive element 215. Similarly, some light is emitted directly through the transmission area of the transmissive element 215. This part of the light is seen by the observer, forming light-emitting points located behind the first layer of light-emitting points. Some light continues to be reflected by the reflection area of the transmissive element 215 to the reflection element 214, such as... Figure 3 As shown, Figure 3 The dashed arrows simply illustrate the path of multiple reflections of light. Thus, the light undergoes multiple reflections between the reflective element 214 and the semi-transparent element 215 before exiting through the semi-transparent element 215. Throughout this process, the intensity of the light decreases with each additional reflection. Each time the light passes through the semi-transparent element 215, it is visible, forming a series of patterns that gradually darken and extend infinitely into the distance, as shown in the image. Figure 10 and Figure 11 As shown, these patterns, when strung together, form a second light pattern 212 that creates a light tunnel effect. It should be explained that since the first light pattern 211 is triangular, the LEDs on the LED bead plate 213 are arranged in a triangular array.
[0075] Furthermore, such as Figure 2 and Figure 3 As shown, the light-emitting component 21 also includes a light-diffusing element 216, which is located between the LED bead plate 213 and the semi-transparent and semi-reflective element 215. Light emitted from the LED bead plate 213 passes through the light-diffusing element 216 and then strikes the semi-transparent and semi-reflective element 215. After being processed by the light-diffusing element 216, the incident light distribution is more uniform and softer. In one specific embodiment, the light-diffusing element 216 can be made of PC material (polycarbonate), a plastic element with a light transmittance of 60%-70%, which can reduce the graininess of the light.
[0076] Furthermore, such as Figure 2 and Figure 3As shown, both the LED bead plate 213 and the light-diffusing element 216 are triangular ring structures, which can form a triangular first light pattern 211, and also minimize the material used in the LED bead plate 213 and the light-diffusing element 216, reducing costs and weight. The semi-transparent and semi-reflective element 215 is a triangular planar structure, which also serves as a warning in appearance. The LED bead plate 213, the light-diffusing element 216, and the semi-transparent and semi-reflective element 215 are arranged in parallel and spaced apart. Preferably, the triangular outlines of the LED bead plate 213, the light-diffusing element 216, and the semi-transparent and semi-reflective element 215 are similar isosceles triangles, and the shapes of the first light pattern 211 and the second light pattern 212 are coordinated and aesthetically pleasing.
[0077] Furthermore, such as Figures 2 to 5 As shown, the LED bead plate 213 has a first hollow region 2131, the light-diffusing element 216 has a second hollow region 2161, and the reflective element 214 is partially located in the space between the first hollow region 2131 and the second hollow region 2161. The LED bead plate 213, the light-diffusing element 216, and the reflective element 214 are rationally distributed, which helps to reduce the thickness of the luminous warning sign 2. Figure 4 and Figure 5 As shown, the orthogonal projections of the light-diffusing element 216 and the reflective element 214 onto the semi-transparent and semi-reflective element 215 do not overlap, thus avoiding mutual obstruction between the light-diffusing element 216 and the reflective element 214 and allowing each optical element to fully perform its function.
[0078] In one implementation, such as Figure 2 and Figure 4 As shown, the light-diffusing element 216 has a triangular ring structure, and the reflective surface 2141 of the reflective element 214 is a curved surface that convexes towards the semi-transparent and semi-reflective element 215. Thus, each layer of the light pattern in the second light pattern 212 formed by the luminous warning sign 2 has an arc-shaped triangle shape, resulting in a more aesthetically pleasing tunnel effect. Preferably, the peripheral contour of the reflective element 214 is an arc-sided triangle, which helps to prevent the light-diffusing element 216 from blocking the space between the reflective element 214 and the semi-transparent and semi-reflective element 215.
[0079] Of course, the method of forming the light tunnel effect of the second light pattern 212 is not limited to the above-described technical solution. In another embodiment, the light-emitting component 21 includes an OLED surface light source (not shown in the figure), and the OLED surface light source includes multiple light-emitting areas distributed sequentially from the outside to the inside. When the light-emitting component 21 emits light, the light intensity of all light-emitting areas decreases sequentially from the outside to the inside, thereby forming a series of patterns that change from bright to dark and extend infinitely into the distance. These patterns, when strung together, form the second light pattern 212 with a light tunnel effect.
[0080] In one implementation, such as Figure 2 , Figure 3 and Figure 6 As shown, the luminous warning sign 2 also includes a housing 22. The front of the housing 22 has a mounting cavity 221, in which the light-emitting component 21 is installed. The housing 22 protects the light-emitting component 21. The housing 22 can be made of PA66 (polyamide 66), which is high-strength and opaque. The housing 22 can be manufactured by injection molding, which is convenient for processing. The reflective element 214, the semi-transparent / semi-reflective element 215, and the light-diffusing element 216 can be manufactured by cutting or injection molding.
[0081] Furthermore, such as Figure 3 and Figure 6 As shown, the mounting cavity 221 is provided with a first mounting step 2211 and a second mounting step 2212 arranged sequentially from the inside to the outside. The light-diffusing element 216 is bonded to the first mounting step 2211, the semi-transparent and semi-reflective element 215 is bonded to the second mounting step 2212, the lamp bead plate 213 is located behind the first mounting step 2211 and is bonded to the periphery of the mounting cavity 221, and the reflective element 214 is partially located in the space between the first hollow region 2131 and the second hollow region 2161. The reflective element 214 passes through the first hollow region 2131 of the lamp bead plate 213 and is bonded to the cavity wall of the mounting cavity 221.
[0082] Furthermore, the semi-transparent and semi-reflective element 215, the light-diffusing element 216, the lamp bead plate 213, and the reflective element 214 are connected to the mounting cavity 221 by adhesive bonding. The adhesive bonding method includes, but is not limited to, 3M tape and adhesive. Preferably, 3M tape is used for bonding, which is convenient for operation and provides a stable bond.
[0083] In one implementation, such as Figure 7 As shown, the outer casing 22 includes a mounting platform 222, abutment protrusions 223, and baffles 224. At least two abutment protrusions 223 are spaced apart and positioned on the mounting platform 222. The baffles 224 surround the mounting platform 222. The height of the abutment protrusions 223 is higher than that of the baffles 224, and the height difference between them is small. The abutment protrusions 223 abut against the vehicle window glass 1. An adhesive layer is provided between the mounting platform 222 and the vehicle window glass 1. Specifically, when installing the luminous warning sign 2 onto the vehicle window glass 1, adhesive is first applied to the mounting platform 222, and then the outer casing 22 is pressed onto the vehicle window glass 1. Because the height of the abutment protrusions 223 is higher than that of the baffles 224, the abutment protrusions 223 can abut against the vehicle window glass 1, creating a certain gap between the mounting platform 222 and the vehicle window glass 1. This ensures that the cured adhesive layer has a certain thickness, guaranteeing a firm bond. The retaining rib 224 surrounds the mounting platform 222 to prevent adhesive from overflowing.
[0084] In one specific implementation, such as Figure 1 , Figure 3 , Figures 6 to 8 As shown, the luminous warning sign 2 is installed on the inner surface of the vehicle window glass 1. The mounting platform 222 surrounds the semi-transparent / semi-reflective element 215, and the mounting platform 222 is also triangular. To ensure that the outer shell 22 can stably abut against the vehicle window glass 1, an abutment protrusion 223 is provided at at least three corners of the mounting platform 222, and an abutment protrusion 223 is provided at the midpoint of each side of the mounting platform 222. Of course, the number and location of the abutment protrusions 223 are not limited to this; other reasonable numbers and locations are also possible.
[0085] The present invention also provides a vehicle, the vehicle including a vehicle body and a window assembly 100, the window assembly 100 being mounted on the vehicle body, and the light-emitting component 21 emitting light when the vehicle is in a preset mode.
[0086] It should be understood that the above embodiments are exemplary and are not intended to encompass all possible implementations included in the claims. Various modifications and changes can be made to the above embodiments without departing from the scope of this disclosure. Similarly, the various technical features of the above embodiments can be arbitrarily combined to form other embodiments of the present invention that may not be explicitly described. Therefore, the above embodiments only illustrate several implementations of the present invention and do not limit the scope of protection of this patent.
