Detailed implementation manners

[0044] Next, the technical solutions in the embodiments of the present application will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments in the present application without creative efforts belong to the scope of protection of the present application.

[0045] In the accompanying drawings, sometimes for clarity, the sizes of the constituent elements, the thicknesses of the layers, or the areas may be exaggerated. Therefore, any implementation of the present disclosure is not necessarily limited to the sizes shown in the figures, and the shapes and sizes of the components in the figures do not reflect the true proportions. In addition, the accompanying drawings schematically show ideal examples, and any implementation of the present disclosure is not limited to the shapes or values shown in the accompanying drawings.

[0046] With the rapid development of automotive electrification, networking, and intelligence, the automobile has evolved from a single means of transportation to a mobile intelligent cockpit. Against this backdrop, automotive lighting plays an increasingly important role in vehicle external interactions. Traditional welcome lights mainly utilize LED light sources and project onto the ground through lenses to provide lighting and create an atmosphere.

[0047] However, in related technologies, common LED welcome lights have only a single color and fixed patterns. As point light sources, LEDs require a relatively complex lens group to achieve the effect of surface projection, resulting in a complex structure and large space occupation, which limits the design flexibility and functionality.

[0048] In view of this, an embodiment of the present application proposes an in-vehicle welcome light. Figure 1 The following shows a schematic structural diagram of an in-vehicle welcome light with the second surface of an optical cover plate recessed towards the first surface proposed in an embodiment of the present application. As Figure 1 shown, the in-vehicle welcome light includes: an OLED light-emitting module and a circuit assembly. The OLED light-emitting module includes: a light-emitting panel; an optical cover plate 23, which is disposed on the light-emitting side of the light-emitting panel. The optical cover plate 23 is configured to transmit and modulate the light emitted by the light-emitting panel, and includes a first surface and a second surface that are oppositely arranged, and the first surface is disposed in contact with the light-emitting surface of the light-emitting panel.

[0049] In the embodiments of the present application, the light source of the vehicle-mounted welcome light is an OLED light-emitting module. Among them, the light-emitting panel of the OLED light-emitting module has a surface-emitting characteristic, providing new design possibilities for the vehicle-mounted welcome light. Compared with the traditional LED point light source, the OLED light-emitting module can provide more uniform and softer light, while reducing the dependence on complex optical systems. Only through the optical cover plate 23, the modulation of the light emitted by the light-emitting panel can be realized, which can not only improve the lighting effect, but also achieve more delicate and dynamic light and shadow effects through precise light control, thereby enhancing the sense of technology and future of the vehicle. In addition, since the light source of the vehicle-mounted welcome light is an OLED light-emitting module, the system can automatically adjust the brightness according to the external light conditions to ensure the best lighting effect in any case, while reducing energy consumption, which conforms to the design concept of energy conservation and environmental protection of modern vehicles.

[0050] In some alternative embodiments, such as Figure 1 shown, the light-emitting panel may be a rigid panel, and the second surface of the optical cover plate 23 is configured to be recessed toward the first surface, so that the optical cover plate 23 forms a concave lens structure, and the light emitted by the light-emitting panel is converged by the optical cover plate 23 to form a clearer picture. In the embodiments of the present application, by setting the optical cover plate 23 as a concave lens structure, the picture can be reduced, the picture clarity can be improved, and the brightness of the projection picture can be increased under the same brightness setting.

[0051] In some alternative embodiments, Figure 3 shows a schematic structural diagram of a vehicle-mounted welcome light in which the second surface of an optical cover plate proposed in an embodiment of the present application protrudes in a direction away from the first surface. As Figure 3 shown, the light-emitting panel may be a rigid panel, and the second surface of the optical cover plate 23 is configured to protrude in a direction away from the first surface, so that the optical cover plate 23 forms a convex lens structure, and the light emitted by the light-emitting panel is diverged by the optical cover plate 23 to form a picture with a larger projection area. In the embodiments of the present application, by setting the optical cover plate 23 as a convex lens structure, the picture can be enlarged.

[0052] In some alternative embodiments, Figure 5The figure shows a schematic structural diagram of a vehicle welcome light in which an optical cover plate and a light-emitting panel in an embodiment of the present application are three-dimensional curved surface structures. The light-emitting panel is a flexible panel, and the optical cover plate 23 is a three-dimensional curved surface structure protruding toward the light-emitting side. The light-emitting panel deforms to adapt to the three-dimensional curved surface structure of the optical cover plate 23 to form a light-emitting surface with a continuous curvature. In the embodiment of the present application, by providing the optical cover plate 23 and the light-emitting panel with three-dimensional curved surface structures, the light-emitting panel realizes curved surface light emission, thereby forming a clear projection picture, expanding the area of the projection picture, enriching the projection effect, and enhancing the technological sense and safety of the whole vehicle.

[0053] In the embodiment of the present application, according to different user requirements, the projection area and picture clarity of the light can be customized through the configuration of the optical cover plate with a convex surface, a concave surface or a three-dimensional curved surface, so as to improve the lighting effect of the vehicle welcome light.

[0054] In some alternative embodiments, in order to improve the ultraviolet resistance of the vehicle welcome light, the optical cover plate 23 is an ultraviolet-resistant transparent optical cover plate. Optionally, the material of the optical cover plate 23 is transparent polycarbonate, and a UV absorber is doped in the optical cover plate 23 to enhance the ultraviolet resistance of the optical cover plate. In the embodiment of the present application, by providing the ultraviolet-resistant transparent optical cover plate, UV light can be preferentially resisted and the device attenuation can be delayed, thereby improving the overall service life of the vehicle welcome light.

[0055] In some alternative embodiments, Figure 2 The figure shows a partial enlarged schematic diagram of area a in a welcome light structure proposed in an embodiment of the present application. Figure 4 The figure shows a partial enlarged schematic diagram of area b in a welcome light structure proposed in an embodiment of the present application. As Figure 2 、 Figure 4 shown, the light-emitting panel includes a light-emitting substrate 21 and a packaging substrate 22. The packaging substrate 22 is disposed on a side of the light-emitting substrate 21 away from the optical cover plate 23. The light-emitting substrate 21 includes a light-emitting area and a bonding area located on one side of the light-emitting area. The light-emitting area is configured to emit light in response to a signal from the circuit component, and the bonding area is configured to form an electrical connection with the circuit component to receive the signal emitted by the circuit component.

[0056] In the embodiment of the present application, as Figure 1 shown, the circuit component includes: a printed circuit board 24, the printed circuit board 24 is disposed on a side of the light-emitting panel away from the optical cover plate 23; a flexible circuit board 25, the flexible circuit board 25 is disposed between the printed circuit board 24 and the light-emitting panel, and the printed circuit board 24 and the bonding area are electrically connected through the flexible circuit board 25.

[0057] Optionally, Figure 11 FIG. shows a schematic diagram of a light source cable of a vehicle-mounted welcome light proposed in an embodiment of the present application, as Figure 1 and Figure 11 shown, the circuit assembly further includes a light source cable 27 for connecting the printed circuit board 24 to an external electrical system.

[0058] In some alternative embodiments, in order to further simplify the structural design of the vehicle-mounted welcome light and reduce space occupation, the flexible circuit board 25 is reversely bonded to the printed circuit board 24. Specifically, as Figure 2 and Figure 4 shown, the flexible circuit board 25 includes a first end and a second end. The first end of the flexible circuit board 25 is bonded and connected to the bonding area of the light-emitting substrate 21. The flexible circuit board 25 extends in the direction of the light-emitting area. The second end is bent in the direction of the light-emitting area and fixed to one side of the encapsulation substrate 22 close to the printed circuit board 24, and the second end of the flexible circuit board 25 is connected to the printed circuit board 24. By folding the second end of the flexible circuit board 25 in the direction of the light-emitting area and fixing it to the back of the encapsulation substrate 22, the routing path of the flexible circuit board 25 is completely hidden in the sandwich space between the light-emitting panel and the printed circuit board 24, saving the Z-axis thickness compared with the traditional co-directional bonding scheme and meeting the strict requirements of vehicle-mounted lamps for thin and light.

[0059] Since the flexible circuit board 25 is connected to the printed circuit board 24 in a reverse bonding manner, the stress concentration area of the flexible circuit board 25 is far from the bonding interface, and the bent part of the flexible circuit board 25 can absorb mechanical shock when the vehicle vibrates. Optionally, in order to further reduce the influence of vehicle vibration on the flexible circuit board 25, as Figure 2 shown, the second end of the flexible circuit board 25 is fixed to one side of the encapsulation substrate 22 close to the printed circuit board 24 through a pressure-sensitive adhesive layer 31, so that the encapsulation substrate 22 and the flexible circuit board 25 are bonded through the pressure-sensitive adhesive layer. When the vehicle vibrates, the pressure-sensitive adhesive layer 31 buffers the stress for the flexible circuit board 25 by deforming.

[0060] Optionally, Figure 6 FIG. shows a partial enlarged schematic diagram of area c in a welcome light structure proposed in an embodiment of the present application, as Figure 6As shown, when the light-emitting panel is a flexible panel and the optical cover plate 23 and the light-emitting panel have a three-dimensional curved surface structure, since there is a larger space between the light-emitting panel and the printed circuit board 24 compared to the solution where the light-emitting panel is a rigid panel, therefore, the first end of the flexible circuit board 25 is bonded and connected to the bonding area of the light-emitting substrate 21, the flexible circuit board 25 extends in a direction away from the light-emitting area, and the second end is bent in the direction of the light-emitting area and fixed to the side of the printed circuit board 24 close to the light-emitting panel, and is bonded and connected to the connector 241 ( Figure 7 shown in).

[0061] In some alternative embodiments, as Figure 2 shown, the first end of the flexible circuit board 25 is connected to the bonding area of the light-emitting substrate 21 through a conductive adhesive layer 32. Optionally, the conductive adhesive layer is a UV-curable adhesive.

[0062] In some alternative embodiments, as Figure 2 shown, the surface of the conductive adhesive layer 32 is covered with a waterproof and sealing layer 35. The waterproof and sealing layer 35 at least covers the outer periphery of the conductive adhesive layer 32 and covers the edges of the light-emitting substrate 21 and the optical cover plate 23. The waterproof and sealing layer 35 is configured to prevent water vapor from invading the interior of the light-emitting substrate 21 and the optical cover plate 23.

[0063] In some alternative embodiments, as Figure 2 shown, the OLED light-emitting module further includes an optical adhesive layer 33. The optical adhesive layer 33 is disposed between the optical cover plate 23 and the light-emitting substrate 21. The optical cover plate 23 and the light-emitting substrate 21 are bonded through the optical adhesive layer 33.

[0064] In some alternative embodiments, Figure 6 shows a partial enlarged schematic diagram of area c in a welcome light structure proposed in an embodiment of the present application. As Figure 6 shown, the vehicle-mounted welcome light further includes a heat dissipation layer 36. The heat dissipation layer 36 is attached to the surface of the light-emitting panel on the side away from the optical cover plate 23. The heat dissipation layer 36 is configured to protect the light-emitting panel and dissipate the heat generated by the light-emitting panel. Optionally, the heat dissipation layer 36 is a metal material with good thermal conductivity. For example, the heat dissipation layer 36 can be copper foil, aluminum foil, etc.

[0065] In the embodiments of the present application, as Figure 1As shown, the vehicle-mounted welcome light further includes a housing 26 for accommodating the OLED light-emitting module and the circuit assembly; the housing 26 is formed with a light-emitting window 41, and the second surface of the optical cover plate 23 is disposed close to the light-emitting window 41, and the light emitted by the light-emitting panel passes through the optical cover plate 23 and is emitted from the light-emitting window 41.

[0066] In some alternative embodiments, as Figure 2 shown, the optical cover plate 23 and the housing 26 are fixedly bonded through a foam adhesive layer 34; the printed circuit board 25 and the housing 26 are fixedly bonded through the foam adhesive layer 34 or the pressure-sensitive adhesive layer 31.

[0067] In some alternative embodiments, Figure 7 FIG. is a schematic structural diagram of a housing provided with a fixing buckle and a limiting boss according to an embodiment of the present application. As Figure 7 shown, in order to better fix the printed circuit board 24 in the housing 26, reduce the space occupied by the vehicle-mounted welcome light, and achieve overall thinness and lightness, at least one fixing buckle 42 and a limiting boss 43 corresponding to the fixing buckle 42 are provided on the inner wall of the housing 26; the edge of the printed circuit board 24 is clamped in the clamping space formed by the fixing buckle 42 and the limiting boss 43, and the printed circuit board 24 realizes six-degree-of-freedom constraint through the fixing buckle 42 and the limiting boss 43, so as to prevent the printed circuit board 24 from shifting during vehicle vibration and affecting the performance of the circuit assembly.

[0068] In some alternative embodiments, when the light-emitting panel and the optical cover plate 23 are three-dimensional curved surface structures, the light-emitting substrate 21 includes a planar state and a three-dimensional curved surface state. Since the light-emitting substrate 21 needs to be changed from the planar state to the three-dimensional curved surface state when being attached to the optical cover plate 23 with a three-dimensional curved surface structure in the OLED light-emitting module, and according to the characteristics of surface geometry, a three-dimensional curved surface with a non-zero Gaussian curvature cannot be unfolded into a two-dimensional plane. Exemplarily, when the light-emitting substrate 21 is a spherical three-dimensional structure in the three-dimensional curved surface state, when the light-emitting substrate 21 in the planar state is changed to the three-dimensional curved surface state, a wrinkling phenomenon will occur at the edge of the spherical three-dimensional structure. Therefore, Figure 8 FIG. shows a schematic structural diagram of a light-emitting substrate in a planar state according to an embodiment of the present application. Figure 9 FIG. shows a schematic structural diagram of a light-emitting substrate in a three-dimensional curved surface state according to an embodiment of the present application. As Figure 8 and Figure 9As shown, in the planar state, a plurality of functional structures 51 are provided at the edge of the light-emitting area 53 of the light-emitting substrate 21. By providing the functional structures 51 in this application, the area of the light-emitting area 53 of the light-emitting substrate 21 at the edge is reduced. When converting from the planar state to the three-dimensional curved surface state, the originally wrinkled area at the edge of the light-emitting area 53 is stretched through the space provided by the functional structures 51, thereby effectively eliminating the wrinkle defects generated at the edge of the light-emitting area 53 in the three-dimensional curved surface state, but forming a junction line as shown in Figure 9 so that the light-emitting substrate 21 forms a light-emitting surface with a continuous curvature in the three-dimensional curved surface state.

[0069] In some alternative embodiments, in the planar state, the functional structure 51 is a notch structure that is recessed towards the center of the light-emitting substrate 21. The functional structure 51 penetrates through both surfaces of the light-emitting substrate 21. The width of the functional structure 51 gradually decreases or remains unchanged in a direction perpendicular to the first direction, and the first direction is the direction from the edge of the light-emitting substrate 21 to the center of the light-emitting substrate 21 in the planar state. Optionally, when the light-emitting substrate 21 is in the planar state, the shape of the functional structure 51 includes at least one of the following: triangle, trapezoid, rectangle, or a combined figure of a straight line and an arc.

[0070] Optionally, in the planar state, the plurality of functional structures 51 are axially symmetrically distributed, and the axis of symmetry passes through the center of the light-emitting substrate 21. Exemplarily, as shown in Figure 8 the light-emitting substrate 21 includes 4 functional structures 51 spaced 90°.

[0071] In some alternative embodiments, Figure 10 shows a schematic diagram of the partition shape of the light-emitting units in a light-emitting substrate proposed in an embodiment of this application. As shown in Figure 10 the light-emitting substrate 21 includes a plurality of light-emitting units arranged in a dense periodic pattern. The light-emitting units are equilateral triangles, and the sub-pixels located within the same light-emitting unit are configured to emit light uniformly, so that the picture projected by the light-emitting substrate 21 forms various patterns based on the light-emitting conditions of the different light-emitting units.

[0072] Combined with the intelligent trend of modern automobiles, the in-vehicle welcome light system in the embodiments of this application can be seamlessly docked with the vehicle's advanced driver assistance system (ADAS). When the vehicle is about to start or turn, the welcome light can remind the surrounding pedestrians and vehicles through specific light effects (light language), thereby improving driving safety. At the same time, the welcome light can also automatically adjust the brightness and color according to the ambient light and driving mode to provide the best visual effect and safety guarantee.

[0073] In practical applications, the in-vehicle welcome light can define different animations and pattern projections according to vehicle usage scenarios. For example, the welcome light can integrate "light language", which can be used to indicate the turning direction, give warnings, create a sense of ceremony, etc. In some alternative embodiments, Figure 14a shows a schematic diagram of an in-vehicle welcome light displaying a right-turn pattern according to an embodiment of the present application. As Figure 14a shown, when the vehicle makes a right turn, the in-vehicle welcome light can control multiple light-emitting units of the light-emitting substrate 21 to emit light, forming a right-turn pattern to alert surrounding vehicles; Figure 14b shows a schematic diagram of an in-vehicle welcome light displaying a left-turn pattern according to an embodiment of the present application. As Figure 14b shown, when the vehicle makes a left turn, the in-vehicle welcome light can control multiple light-emitting units of the light-emitting substrate 21 to emit light, forming a left-turn pattern to alert surrounding vehicles. It should be noted that the turning pattern can be a fixed turning pattern or a dynamic flowing-turning animation, which can be specifically determined according to actual situations and requirements, and the present application does not make specific limitations here.

[0074] In some alternative embodiments, Figure 15 shows a schematic diagram of an in-vehicle welcome light displaying a brand logo pattern according to an embodiment of the present application. As Figure 15 shown, when the driver or passenger gets in the car and opens the door, the in-vehicle welcome light can control multiple light-emitting units of the light-emitting substrate 21 to emit light to form a brand logo pattern or other patterns to create a sense of ceremony. Exemplarily, when the brand logo is "VW", the in-vehicle welcome light forms a "VW" brand logo pattern as Figure 15 shown.

[0075] In some alternative embodiments, Figure 16 shows a schematic diagram of an in-vehicle welcome light displaying a warning pattern according to an embodiment of the present application. As Figure 16 shown, when an emergency occurs (such as the vehicle stops, the driver or passenger gets out of the car, or the vehicle breaks down and the emergency flashers are turned on, etc.), the in-vehicle welcome light can control multiple light-emitting units of the light-emitting substrate 21 to emit light to form a warning pattern to alert surrounding vehicles and pedestrians of the current state of the vehicle and avoid accidents. Exemplarily, the in-vehicle welcome light forms a warning logo pattern of an "exclamation mark" as Figure 16 shown.

[0076] The present application provides a vehicle welcome light and a vehicle. The vehicle welcome light includes an OLED light-emitting module and a circuit component. The OLED light-emitting module includes: a light-emitting panel; an optical cover plate which is disposed on the light-emitting side of the light-emitting panel and includes a first surface and a second surface which are oppositely arranged. The first surface is attached to the light-emitting surface of the light-emitting panel.
