[0001] The utility model relates to the technical field of vehicle lamps, and particularly relates to an interactive lamp and a vehicle. Background Art

[0002] With the increasing demand for vehicle intelligence, intelligent interactive lamps have become the mainstream configuration of intelligent vehicles. The interactive lamps are not only used for lighting, but also can interact with the outside world according to some custom or predefined patterns.

[0003] The interactive lamps in the prior art are gradually increasing in size. Generally, the vehicle body surface is a curved surface. Since the interactive lamps need to be integrated into the vehicle body structure, the larger interactive lamps also need to be arranged according to the curved surface. For multi-pixel interactive lamps, a flexible circuit board usually needs to be arranged inside to form a curved surface structure. However, the flexible circuit board has a high cost, and is easily torn or has loose LED joints during the production process, resulting in poor reliability. Summary of the Utility Model

[0004] In view of the above-mentioned disadvantages of the prior art, the purpose of the present utility model is to provide an interactive lamp and a vehicle to reduce the cost of large-size interactive lamps.

[0005] To achieve the above purpose and other related purposes, the present utility model provides an interactive lamp applied to a vehicle. The interactive lamp has a shaping curved surface, and includes:

[0006] A plurality of rigid circuit boards are provided, and the rigid circuit boards are arranged at an angle, and the arrangement direction of the rigid circuit boards is the same as the bending direction of the shaping curved surface;

[0007] A plurality of lamp beads are arranged in an array on the outer side of the rigid circuit board;

[0008] An outer cover is provided on the outer side of the lamp beads, and the outer cover is made of a light-transmitting material.

[0009] In a specific embodiment of the present utility model, the size of the rigid circuit board decreases as the curvature of the shaping curved surface in the corresponding area increases.

[0010] In a specific embodiment of the present utility model, the rigid circuit board is a rectangular plate structure, and the arrangement areas of the plurality of rigid circuit boards cover the display area of the interactive lamp.

[0011] In a specific embodiment of the present utility model, the rectangular sides of adjacent rigid circuit boards are arranged in a fitting manner.

[0012] In a specific embodiment of the present utility model, the shaped curved surface is a long strip curved surface. The shaped curved surface includes a first region and a second region.

The first region and the second region are respectively provided with a first group and a second group, and the first group and the second group respectively include a plurality of the rigid circuit boards.

[0013] In a specific embodiment of the present utility model, a plurality of the rigid circuit boards in the first group are arranged in the same direction. The arrangement direction of the plurality of rigid circuit boards in the first group is the same as the length bending direction of the long strip curved surface, and the arrangement mode of the rigid circuit boards in the second group is the same as that of the first group.

[0014] In a specific embodiment of the present utility model, the position of the maximum curvature in the region of the shaped curved surface corresponding to adjacent rigid circuit boards in the first group is the maximum curvature line, and the intersection line of adjacent rigid circuit boards is arranged corresponding to the maximum curvature line.

[0017] The present utility model also provides a vehicle, including the interactive lamp as described above.

[0018] The present utility model provides an interactive lamp and a vehicle. In the above solution, the structure of an approximate curved surface is formed by the angular arrangement and connection of multiple rigid circuit boards, avoiding the use of flexible circuit boards to reduce costs.

The present utility model can also be implemented or applied through other different specific implementation manners. Various details in this specification can also be modified or changed based on different viewpoints and applications without departing from the spirit of the present utility model. It should be noted that, without conflict, the following embodiments and the features in the embodiments can be combined with each other.

[0027] It should be noted that the diagrams provided in the following embodiments only illustrate the basic concept of the present utility model in a schematic manner. Therefore, only the components related to the present utility model are shown in the diagrams, rather than being drawn according to the number, shape, and size of the components in actual implementation. The types, quantities, and proportions of the components in actual implementation can be arbitrarily changed, and the component layout type may also be more complex.

[0028] An interactive lamp refers to a lighting device on a vehicle, which is used to interact with other road users or pedestrians to transmit the state, intention, or warning information of the vehicle. Such an interactive lamp system can improve road safety and make it easier for drivers and pedestrians to understand the driving intention or current state of the vehicle.

[0029] An interactive lamp generally includes multiple LED matrices composed of multiple lamp beads 30 and a digital micromirror projection chip. When driving normally, the interactive lamp can serve as an additional supplement to the daytime running lamp, position lamp, turn signal lamp, brake lamp, and reverse lamp, enhancing the display effect of the headlamp group; in certain specific scenarios, the interactive lamp group can display dynamic interactive graphics pre-set by the manufacturer, including graphics such as forward collision warning, rear vehicle collision warning, intersection U-turn reminder, and charging status display. In addition to being able to display built-in interactive graphics, if the vehicle opens the function editing permission of the lamp to the user, under the premise of compliance with regulations, the user can also create their own emoticons, specific patterns, etc. for display.

[0030] An interactive lamp in the prior art is as Figure 1 shown, which includes a substrate, a flexible circuit board 1, lamp beads 30, and an outer cover 50. Multiple lamp beads 30 are arranged in an array on the outer side of the flexible circuit board 1. The flexible circuit board 1 (FPC) is a bendable circuit board that allows for flexible wiring and design in the lamp. FPC is usually used in complex shapes or areas that require bending to adapt to the appearance design of the lamp. Due to its flexibility, the FPC can adapt to the curves or complex shapes of the lamp's outer shape, enabling the lamp to achieve a more flexible design. However, the flexible circuit board 1 (FPC) is usually more expensive than the rigid circuit board 20 (PCB) because its production process is complex and the material cost is high.

[0031] As Figures 2 - 4 shown, an interactive lamp and a vehicle are provided to reduce the cost of a large-sized interactive lamp.

[0032] To achieve the above and other related purposes, the present utility model provides an interactive lamp applied to a vehicle. The interactive lamp has a shaping curved surface and includes a rigid circuit board 20, lamp beads 30, and an outer cover 50.

[0033] The shaping curved surface can be a curved surface with multiple bending dimensions, specifically determined by the shaping of the interactive lamp. Specifically, the shaping curved surface can be the curved surface of the outer cover 50 as Figure 4 shown.

[0034] There are multiple rigid circuit boards 20, and the arrangement direction of the rigid circuit boards 20 is the same as the bending direction of the shaped curved surface. The rigid circuit board 20 has higher mechanical strength compared to the flexible circuit board 1, can better support and protect the circuit, and is suitable for structures that require a certain degree of strength and stability. The rigid circuit board 20 usually has better durability and can withstand greater mechanical stress and environmental changes. Multiple rigid circuit boards 20 can be flexibly formed into various shapes and structures through angular arrangement and connection methods to meet different design requirements. This allows for more adjustments and optimizations during the design process. Dividing the circuit board into smaller pieces can simplify the assembly process and make it easier to repair or replace individual circuit boards in some cases. Although the rigid circuit board 20 itself is flat, the curved surface can be approximately formed to a certain extent through angular arrangement.

[0035] Light beads 30, and multiple light beads 30 are arranged in an array on the outer side of the rigid circuit board 20. The light beads 30 are LED light sources, which are connected and controlled through the circuit on the rigid circuit board 20. The arrayed light beads 30 can form various pattern changes through their own brightness or color changes.

[0036] The outer cover 50 is arranged on the outer side of the light beads 30, and the outer cover 50 is made of a light-transmitting material. A light-blocking film is provided on the inner side surface of the outer cover 50, and the light-blocking film is configured to allow light with a brightness exceeding a threshold value to pass through. The light-blocking film is a thin film or coating that can control the degree of light transmission. The light-blocking film is designed to allow light above a certain brightness level to penetrate. The specific meaning of the light-blocking film is that when the light beads 30 are lit, the lighting effect of the light beads 30 can be seen from the outside, and when the light beads 30 are not lit, only the color of the light-blocking film itself can be seen from the outside, and other structures inside the light-blocking film cannot be seen. The light-blocking film is a coating on the inner side surface of the outer cover 50, specifically a steel coating.

[0037] As Figure 5 shown, the size of the rigid circuit board 20 decreases as the curvature of the corresponding area of the shaped curved surface increases. Using a small-sized rigid circuit board 20 in areas with large curvature changes can more precisely adapt to complex curved surfaces, ensuring that the light beads can effectively illuminate in these areas and avoiding uneven light spots or shadows. Using a large-sized rigid circuit board 20 in areas with small curvature changes can effectively cover a larger area, reduce the number of rigid circuit boards 20, and thus simplify the overall design and assembly process.

[0038] As Figure 5As shown, the rigid circuit board 20 is a rectangular board structure, and the arrangement areas of multiple rigid circuit boards 20 cover the display area of the interactive lamp. The shape of the rectangular rigid circuit board 20 makes the design and production processes more standardized, simplifying the manufacturing and assembly steps. The rectangular board can be conveniently arranged modularly, is easy to splice and combine, and thus can more flexibly cover the display area. The installation and alignment of the rectangular circuit board are relatively simple, reducing the difficulty and error rate during the installation process. The reasonably arranged rectangular rigid circuit board 20 can effectively cover the display area, ensuring uniform distribution of the light from the lamp beads and improving the overall display effect.

[0039] As Figure 5 shown, the rectangular sides of adjacent rigid circuit boards 20 are arranged in contact. The edge contact arrangement makes the assembly process of the circuit boards simpler and more standardized. The rectangular edge contact arrangement makes the docking of the circuit boards more precise. When installing, the circuit boards can be directly aligned like Figure 1 puzzle pieces, reducing the complex operations caused by misalignment or improper adjustment. This simplified assembly process improves work efficiency, reduces working hours and human errors. The edge contact arrangement can ensure more uniform distribution of the lamp beads on the circuit board. This arrangement helps to achieve uniform light dispersion, reducing light spots and dark areas and improving the overall lighting effect. The rectangular edge contact arrangement can maximize the use of available space and reduce the gaps between circuit boards. This compact design not only optimizes the use of space but also helps to improve the design density and aesthetics of the entire system.

[0040] As Figure 4 shown, the shaped surface is a long strip-shaped surface. The shaped surface includes a first region 11 and a second region 12. The boundary between the first region 11 and the second region 12 is the position of the maximum curvature in the width direction of the long strip-shaped surface. A first group 21 and a second group 22 are respectively arranged corresponding to the first region 11 and the second region 12, and the first group 21 and the second group 22 respectively include multiple rigid circuit boards 20.

[0041] The length direction of the long strip-shaped surface is arranged along the vehicle width direction, and the width direction of the long strip-shaped surface corresponds to the up-down direction of the vehicle. The arrangement along the vehicle width direction in this application means approximately along the vehicle width direction, not strictly parallel to the vehicle width direction.

[0042] Taking the position with the largest change in the shaping curvature in the up-down direction as the dividing line, the curved surface is divided into two parts, and then the best-fit planes of the upper and lower curved surface segments are respectively fitted, which are used as the reference direction planes of the rigid circuit board 2020 in the up-down direction. Setting the dividing line at the position with the largest curvature change in the up-down direction can make the reference planes of the upper and lower curved surface segments more conform to the actual shape, ensuring more accurate fitting of the circuit board. Fitting the best-fit planes of the upper and lower curved surface segments respectively as the reference direction planes can enhance the alignment and fixing accuracy during the assembly process of the circuit board and reduce the installation error.

[0043] As Figure 5 shown, multiple rigid circuit boards 20 in the first group 21 are arranged in the same direction, that is, the rigid circuit boards 20 in the first group 21 form a row of rigid circuit boards 20. The arrangement direction of the multiple rigid circuit boards 20 in the first group 21 is the same as the length bending direction of the long-strip curved surface, and the arrangement mode of the rigid circuit boards 20 in the second group 22 is the same as that of the first group 21. Considering the trend of the shaping curvature change and the number of LED control chip channels, the curved surface can be unevenly divided into 10 regions in the first region 11 and the second region 12 respectively, and the best-fit planes of each curved surface segment are respectively fitted, which are used as the reference direction planes of the rigid PCB board in the vehicle-width direction. There are complex changes in the curved surface in the vehicle-width direction. Dividing the curved surface into 10 regions and respectively fitting the best-fit planes can more accurately adapt to the curved surface shape, thereby ensuring that each circuit board can be well fitted to the curved surface. By subdividing the regions and fitting the best-fit planes in each region, the error in the overall assembly process can be reduced, ensuring the precise alignment of the circuit boards in the vehicle-width direction and improving the assembly quality and consistency.

[0044] In a specific embodiment of the present invention, the surface where the rigid circuit board 20 is located is the best-fit plane in the corresponding shaping curved surface. The matching accuracy between the best-fit plane and the curved surface is high, which means that each circuit board can be accurately fitted to the curved surface of the substrate 10. On a complex shaping curved surface, using the best-fit plane can more effectively utilize the space. It can ensure the best circuit board layout within the limited space, maximizing the function and performance of the device. The best-fit plane refers to the plane that is determined by mathematical and geometric methods and is closest to the given curved surface (shaping curved surface) on the curved surface. It is to find a plane on the curved surface such that the distance between the plane and the curved surface (usually measured using the least square error, least squares method or other optimization criteria) is the smallest.

[0045] For example, the process of calculating the best-fit plane using the least squares method is as follows:

[0046] First, obtain the data points on the curved surface.

[0047] Define the form of the plane model.

[0048] Construct a least - squares objective function based on the data points to measure the error between the plane and the data points. The goal of the least - squares method is to find a plane that minimizes the sum of the squares of the perpendicular distances from all data points to the plane. This plane is the best - fitting plane.

[0049] In a specific embodiment of the present utility model, the position of the maximum curvature in the region corresponding to the shaped surface of the adjacent rigid circuit boards 20 in the first group 21 is the maximum - curvature line, and the intersection line of the adjacent rigid circuit boards 20 is arranged corresponding to the maximum - curvature line. The arrangement of the rigid circuit boards in the second group 22 is the same as that of the first group 21. Since the curvature at the position of the maximum curvature is relatively large, it is difficult for the rigid circuit board 20 to be close to it. Therefore, the intersection line of the adjacent rigid circuit boards 20 is set at this place. Setting the intersection line in the maximum - curvature region can make the circuit boards easier to align and fix during the assembly process, avoiding the problem of uneven fitting in the extreme - curvature region. This can ensure the correct positioning and stability of the circuit boards in the overall structure. The intersection line located in the maximum - curvature region can make the circuit boards easier to align, avoiding the problem of uneven fitting caused by the surface deformation in the high - curvature region, thereby improving the consistency and accuracy of the overall assembly.

[0050] As Figure 2 shown, the boundaries of the adjacent rigid circuit boards 20 are aligned, and this boundary alignment means approximately aligned. When the boundaries of multiple circuit boards are aligned, the light - emitting surfaces of the lamp beads 30 will be arranged more neatly, thereby improving the uniformity and consistency of the light. This is particularly important for the interactive lighting effect of the vehicle, which can ensure that the light is evenly distributed on the entire surface of the lamp, avoiding the appearance of light spots or uneven display effects. The aligned boundaries can simplify the installation and fixing process of the circuit boards, making the assembly process more efficient and accurate, and reducing the assembly error.

[0051] As Figure 2 shown, an inner lamp cover 40 is provided between the lamp bead 30 and the outer lamp cover 50. The inner lamp cover 40 can be a light - homogenizing plate or a grating partition. The grating partition has light - concentrating holes, and the light - concentrating holes are arranged corresponding to the lamp beads 30.

[0052] If a light-diffusing plate is used, the light beam emitted by the lamp bead 30 forms a uniform light source after being diffused by the light-diffusing plate. The setting of the light-diffusing plate can transform the original display effect with a strong sense of grain into a uniform luminous surface pattern, thereby improving the picture display effect. The outer surface of the light-diffusing plate is covered with a shading layer, and the light-diffusing layer is provided with an array-arranged light-transmitting area at the position corresponding to the lamp bead 30, and the array density of the light-transmitting area is greater than the array density of the lamp bead 30. The light beam emitted by the lamp bead 30 forms a uniform surface light source after being diffused by the light-diffusing plate, and then the light-transmitting area is divided into a plurality of independent pixel points by the light-diffusing layer. The light-diffusing layer can shield part of the scattered stray light, thereby turning the light-transmitting area with unclear boundaries into a pixel array with clear boundaries and orderly arrangement, thereby presenting a high-pixel display effect. The light-shielding layer is a black coating applied or attached to the outside of the light-diffusing plate, and then the light-shielding layer is engraved by laser engraving to remove part of the black part, and the light-transmitting area is a hole-shaped.

[0053] If a grating partition is used, the focusing hole can focus the divergent light beams emitted by the lamp beads 30 to form a more concentrated light spot. This can increase the brightness and intensity of the light, make the light beam more focused, and thus improve the display effect. Through the focusing hole, the light beam can be adjusted to the desired shape, reducing the divergence of the light spot, making the light spot sharper and clearer. This helps to improve the expressiveness of the picture and make the image and text clearer and more readable.

[0054] In a specific embodiment of the present invention, the rigid circuit board 20 is connected to the inner lampshade 40. Specifically, the connection is performed by a hot riveting process. The inner lampshade 40 can be connected to the integral bracket, so that the back plate of the rigid circuit board can be eliminated, saving costs and reducing weight. At the same time, riveting provides a reliable mechanical connection, increases the stability between the rigid circuit board 20 and the inner lampshade 40, and reduces the possibility of movement or vibration. Compared with welding or other connection methods, riveting generally performs better in terms of connection strength and tensile resistance, and is suitable for withstanding greater physical pressure and impact.

[0055] The utility model also provides a vehicle, comprising the above-mentioned interactive lamp.

[0056] In summary, the utility model proposes an interactive light and a vehicle. In the above scheme, a plurality of rigid circuit boards 20 are arranged and connected at an angle to form a structure approximating a curved surface, avoiding the use of a flexible circuit board 1 to reduce costs. The rigid circuit board 20 has higher mechanical strength than the flexible circuit board 1 and can better support and protect the circuit. The plurality of rigid circuit boards 20 can be flexibly formed into various shapes and structures through angle arrangement and connection to meet different design requirements. In this way, more adjustments and optimizations can be made during the design process.
