Description
Technical Field
[0001] This application belongs to the technical field of vehicle steering, and in particular relates to an OLED turn signal and a vehicle. Background Technology
[0002] Turn signals are indicator lights that flash in the corresponding direction when a vehicle is turning, alerting pedestrians or vehicles in front or behind the vehicle to indicate the vehicle's direction of travel and ensuring the safety of the vehicle itself as well as other vehicles and pedestrians. Currently, most turn signals are long and thin, and only have a flashing function, resulting in a limited range of lighting effects and directions, and thus a relatively simple indication, failing to provide a satisfactory warning.
[0003] It should be noted that the information disclosed in the background section above is only used to enhance the understanding of the background of this disclosure, and therefore may include information that does not constitute prior art known to those skilled in the art. Summary of the Invention
[0004] This application aims to at least partially solve the technical problems of turn signals having poor lighting effects and a single light direction, thus failing to provide a good warning effect. To this end, this application provides an OLED turn signal and a vehicle.

[0015] In some embodiments, the flexible OLED light sheet includes a flexible OLED panel layer and a back sheet layer for supporting the flexible OLED panel layer. The area of the back sheet layer corresponding to the edge of the bracket is a back sheet weakening bending area, which is locally weakened by punching or etching processes.
[0016] In some embodiments, the thickness of the backsheet layer is 0.5 mm to 0.8 mm.
[0017] This application also provides a vehicle that includes the aforementioned OLED turn signals.

Detailed Implementation
[0034] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of the embodiments. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this application.
[0035] Furthermore, reference numerals and / or reference letters may be repeated in different examples in this application. Such repetition is for simplification and clarity purposes and does not in itself indicate a relationship between the various embodiments and / or settings discussed. In addition, this application provides examples of various specific processes and materials; however, those skilled in the art will recognize the application of other processes and / or the use of other materials.
[0036] This application is described below with reference to the accompanying drawings and specific embodiments:
[0037] This application provides an OLED turn signal, such as Figure 1 and Figure 6 As shown, the OLED turn signal includes a bracket 100 and an OLED light sheet. The bracket 100 includes a bottom surface 110 for connection with the vehicle body and a plurality of support surfaces 120 connected to the bottom surface 110. Two adjacent support surfaces 120 are connected to each other. The OLED light sheet is disposed on the plurality of support surfaces 120.
[0038] The OLED turn signal disclosed in this application uses an OLED light sheet as a light source. By setting the OLED light sheet on the support surface 120 of the bracket 100, a three-dimensional turn signal structure can be formed, which can make the turn signal have multiple light emission directions so that vehicles and pedestrians in all directions can see it. At the same time, by utilizing the advantages of OLED itself, it can display display effects such as flowing turn signals and multiple animation transitions, which can improve the indication effect of the OLED turn signal and thus achieve a better warning effect.
[0039] In related technologies, traditional side turn signals often use LED (Light-Emitting Diode) bulbs or halogen bulbs with lamp covers. Due to the limited space for side turn signals and the small size of LED or halogen bulb assemblies, the side turn signals are often long and thin with a poor design and limited display effect, failing to provide a good warning effect.
[0040] In this application, the bracket 100 includes a bottom surface 110 for connection with the vehicle body and multiple support surfaces 120 connected to the bottom surface. Adjacent support surfaces 120 are interconnected, thus forming a three-dimensional support structure. This allows OLED light sheets to cover and be disposed on the multiple support surfaces 120, thereby creating a light-emitting display that emits light in multiple directions. The light emission method uses OLED light sheets. OLED (Organic Light-Emitting Diode) has advantages such as light weight, low power consumption, long lifespan, no heat generation, surface emission, and no need for a reflective mechanism to ensure the light emission effect. Using OLED light sheets as the light source eliminates the need for a reflective mechanism and reduces the requirement for heat dissipation space. Therefore, it can be used in smaller turn signal placement spaces for more complex or diverse turn signal design needs, resulting in more diverse turn signal indication effects and enhancing the overall technological feel and atmosphere of the vehicle. Furthermore, OLED light sheets have the ability to be individually controlled and edited for different zones, resulting in more diverse display effects that are easier to notice and observe, thereby improving the warning effect of OLED turn signals and enhancing driving safety.
[0041] In this application, the shape of the bracket 100 can be adopted in different ways according to design requirements. For example... Figure 2 and Figure 7 As shown, the bracket 100 adopts a polyhedral structure, for example, the bracket 100 is a tetrahedral structure; accordingly, the OLED light sheet is set on the support surface 120 of the polyhedral structure bracket 100, so that the OLED turn signal has a polyhedral structure as a whole, which can enable the OLED turn signal to emit light in multiple directions, and can also meet certain appearance design requirements of the OLED turn signal.
[0042] As an optional implementation, the support 100 is made of plastic.
[0043] In this application, the bracket 100 can be made of plastics such as ABS (acrylonitrile-butadiene-styrene copolymer). The plastic material can be made into a bracket 100 by injection molding process. The bracket 100 can be made into a specific shape according to the design requirements of the bracket 100, so that the wall thickness of the bracket 100 is 2.0mm to 2.5mm. The molded bracket 100 is an integral structure, and its strength can meet the support strength requirements of the OLED turn signal.
[0044] As an optional implementation, the OLED turn signal further includes:
[0045] The flexible circuit board 300 is electrically connected to the OLED light sheet, and the support 100 has through slots 130 corresponding to the position and number of the flexible circuit board 300.
[0046] In this application, as Figure 2and Figure 7 As shown, the OLED panel is electrically connected to the flexible circuit board 300, which in turn connects to the vehicle's battery and other power supply devices to provide power to the OLED panel, enabling it to display according to design requirements. Simultaneously, since the OLED panel is mounted on the support surface 120 of the bracket 100, a through slot 130 is provided on the bracket 100 to allow the flexible circuit board 300, which is electrically connected to the OLED panel, to enter the bracket or vehicle interior and connect to the vehicle's power supply devices. The position and number of the through slots 130 correspond to the position and number of the flexible circuit boards 300, ensuring that each flexible circuit board 300 can enter the vehicle interior.
[0047] In such Figure 1 and Figure 2 In the illustrated embodiment, the bracket 100 of the OLED turn signal has a tetrahedral structure. One side of the tetrahedron serves as the bottom surface 110 for mounting the OLED turn signal on the vehicle, while the other three sides serve as support surfaces 120 for supporting the OLED LED panels. The OLED turn signal in this embodiment includes three OLED LED panels, each mounted on one of the three support surfaces 120. Each OLED LED panel is connected to a flexible circuit board 300. Therefore, a through slot 130, matching the width of the flexible circuit board 300, can be provided on the bottom plate at a position corresponding to the flexible circuit board 300, allowing the flexible circuit board 300 to enter the bracket 100 through the through slot 130.
[0048] In such Figure 6 and Figure 7 In the illustrated embodiment, the bracket 100 of the OLED turn signal has a tetrahedral structure. One side of the tetrahedron serves as the bottom surface 110, used to mount the OLED turn signal on the vehicle, while the other three sides serve as support surfaces 120, used to support the OLED light sheet. The OLED turn signal in this embodiment includes an OLED light sheet, which is bent and attached to the three support surfaces 120. Simultaneously, the OLED light sheet is connected to a flexible circuit board 300. Therefore, a through slot 130, matching the width of the flexible circuit board 300, can be formed on the bottom plate at a position corresponding to the flexible circuit board 300, allowing the flexible circuit board 300 to enter the bracket 100 through the through slot 130.
[0049] As an optional implementation, the surface of the flexible circuit board 300 at the electrical connection point with the OLED lamp sheet is coated with optically curable adhesive and waterproof adhesive 310.
[0050] In this application, since OLED turn signals are mostly used outdoors, there is a risk of corrosion from rain, snow, and moisture. To protect the electrical connection between the flexible circuit board 300 and the OLED light sheet, ensure a more reliable bond between them, and prevent moisture intrusion that could cause short circuits or burnout of the OLED light sheet, an optically curable adhesive and a waterproof adhesive 310 are layered and coated on the surface of the electrical connection between the flexible circuit board 300 and the OLED light sheet. Specifically, the optically curable adhesive (UV adhesive) is first used to fix the electrical connection between the flexible circuit board 300 and the OLED light sheet to the bracket, and then the waterproof adhesive is applied. This forms a double-layer adhesive film on the surface of the electrical connection between the flexible circuit board 300 and the OLED light sheet, which has both fixing and waterproofing functions, preventing moisture from intruding into the OLED light sheet and damaging its light-emitting effect.
[0051] As an optional implementation, the light-emitting surface of the OLED lamp sheet is provided with a filter film 400.
[0052] In this application, OLED turn signals are primarily used outdoors. For example... Figure 5 and Figure 9 As shown, a filter film 400 can be attached to the light-emitting surface of the OLED light sheet. The filter film 400 blocks ultraviolet rays from shining on the OLED light sheet, thereby protecting the OLED light sheet and extending its service life.
[0053] As an optional implementation, the OLED light sheet includes a plurality of rigid OLED light sheets 210, the shapes of the plurality of rigid OLED light sheets 210 corresponding one-to-one with the shapes of the plurality of support surfaces 120.
[0054] In this application, the OLED light sheet on the OLED turn signal can be a rigid OLED light sheet 210. Since the rigid OLED light sheet 210 is not suitable for bending, the number of rigid OLEDs must be the same as the number of support surfaces 120, and the shape of the rigid OLED light sheet 210 must correspond one-to-one with the shape of the support surface 120, so that the rigid OLED light sheet 210 can completely cover all the support surfaces 120 of the bracket 100.
[0055] like Figure 2 and Figure 3As shown, in Embodiment 1, the OLED turn signal has three triangular rigid OLED panels 210 and a tetrahedral plastic bracket 100. One face of the bracket 100 serves as the bottom face 110, and the other three faces serve as support faces 120. Two of the support faces 120 have mirror-symmetrical obtuse triangles, and the remaining support face 120 is an isosceles triangle. Correspondingly, of the three rigid OLED panels, two are mirror-symmetrical obtuse triangles with the same outline shape as the two mirror-symmetrical support faces 120; the remaining rigid OLED panel is an isosceles triangle with the same outline shape as the isosceles triangle support face 120. The three rigid OLED panels are spliced and bonded to the three support faces 120 of the bracket 100 using adhesive materials such as PSA (Pressure Sensitive Adhesive). Figure 1 As shown, three rigid OLED light panel splicing seams P1 are formed on the bracket 100, forming three OLED turn signals that can emit light from three sides. Simultaneously, through slots 130 are provided on the bottom surface 110 at corresponding positions to the flexible circuit boards 300 of the three rigid OLED light panels 210, allowing the flexible circuit boards 300 to pass through. The bottom surface 110 serves as a mounting plane, used to contact the vehicle's sheet metal for fixation to the vehicle.
[0056] In other embodiments, the appearance of the rigid OLED light sheet 210 can be adjusted according to the structure of the bracket 100. At the same time, in order to ensure the three-dimensionality of the OLED turn signal light emission direction, three rigid OLED light sheets 210 are required.
[0057] like Figure 3 and Figure 5 As shown, in Embodiment 1, the rigid OLED light sheet 210 includes a sequentially stacked encapsulation glass layer 212 and a rigid OLED panel layer 213. An adhesive layer 211 is provided on the side of the encapsulation glass layer 212 away from the rigid OLED panel layer 213. The adhesive layer 211 can be made of PSA material, allowing the rigid OLED light sheet 210 to be adhered to the support surface 120 via the adhesive layer 211. A light-emitting film 400 is provided on the light-emitting surface of the rigid OLED panel layer 213 to block ultraviolet radiation from reaching the OLED light sheet, thus protecting the OLED light sheet and extending its lifespan. Furthermore, the bottom of the rigid OLED light sheet 210 is bonded to the flexible circuit board 300 for electrical connection. An optically curable adhesive and a waterproof adhesive 310 are coated on the surface of this connection to fix the connection between the flexible circuit board 300 and the rigid OLED light sheet to the support and to prevent moisture intrusion.
[0058] As an optional implementation, the OLED light sheet is a flexible OLED light sheet 220, and the shape of the flexible OLED light sheet 220 is the same as the unfolded shape of all the support surfaces 120 of the bracket 100.
[0059] In this application, the OLED light sheet on the OLED turn signal can be a flexible OLED light sheet 220. Since the flexible OLED light sheet 220 is bent, the shape of the flexible OLED light sheet 220 can be the same as the unfolded shape of all the support surfaces 120 of the bracket 100. The flexible OLED light sheet 220 is attached to each support surface 120 by bending.
[0060] like Figure 6 and Figure 7 As shown in Embodiment 2, since the OLED turn signal uses a flexible OLED sheet 220, meaning the OLED turn signal can utilize a single flexible OLED sheet 220, which is bonded to the bracket 100 via a PSA (Power Suppressor Assembly), only one flexible OLED sheet splicing seam P2 is formed on the bracket 100. Compared to the rigid OLED sheet 210, the number and overall length of the flexible OLED sheet splicing seams P2 formed by the flexible OLED sheet 220 are relatively reduced. This means fewer non-luminous flexible OLED sheet splicing seams P2 and a larger continuously luminous area, resulting in a better integrated effect for the OLED turn signal. Furthermore, the flexible OLED sheet 220 can adapt to more complex shapes to meet the needs of more complex or novel OLED turn signal designs.
[0061] As an optional implementation, the flexible OLED light sheet 220 includes a flexible OLED panel layer 224 and a back sheet layer 221 for supporting the flexible OLED panel layer 220. The area of the back sheet layer 221 corresponding to the edge of the bracket 100 is a weakened bending area, which is locally weakened by punching or etching processes.
[0062] like Figure 8 and Figure 9As shown in Embodiment 2, the flexible OLED panel 220 includes a backplate layer 221, an adhesive layer 222, a substrate layer 223, and a flexible OLED panel layer 224 stacked sequentially. The shape of the backplate layer 221 is the same as the unfolded shape of all the support surfaces 120 of the bracket 100. The non-emitting surface of the flexible OLED panel layer 224 is attached to the substrate layer 223, and an adhesive layer 222 is further formed by PSA to connect it to the backplate layer 221. In this embodiment, the backplate layer 221 can be made of metal, and commonly used materials for backplates include aluminum alloy and stainless steel. Meanwhile, a light filter film 400 is provided on the emitting surface of the flexible OLED panel layer 224 to improve its UV resistance.
[0063] like Figures 8 to 10 As shown, in Embodiment 2, the flexible OLED light sheet 220 is bent to adhere to the three support surfaces 120 of the bracket 100, forming two flexible OLED light sheet bending areas P3 on the flexible OLED light sheet 220. Simultaneously, to facilitate the bending of the flexible OLED light sheet 220 along the shape of the bracket 100, the area corresponding to the edge of the backplate layer 221 and the bracket 100 is weakened, forming a backplate weakening bending area P4 on the backplate layer 221. This allows the flexible OLED light sheet 220 to be bent as a whole, enabling it to conform to the shape of the bracket 100 and better adhere to the multiple support surfaces 120. The weakening treatment can employ weakening processes such as punching or etching.
[0064] As an optional implementation, the thickness of the backsheet layer 221 is 0.5 mm to 0.8 mm.
[0065] In this application, in order to make the back sheet layer 221 easier to bend, the thickness of the back sheet layer 221 is 0.5mm to 0.8mm. This thick back sheet can support the flexible OLED panel layer 224 and also avoid the substrate layer being too thick and difficult to bend.
[0066] The OLED turn signal of this application allows for zoned control of the OLED light panel according to design requirements, thereby enabling the OLED turn signal to have richer display effects. For example, the OLED light panel can be set into different zones as needed, and different dynamic patterns can be formed by controlling the display order or whether each zone displays its own pattern. Figure 4 and Figure 11As shown in this application, the OLED light sheet can be divided into multiple parallel strip display areas. When the OLED turn signal is not working, all strip display areas are off. When the OLED turn signal is working, the spaced strip display areas can be lit, and the OLED turn signal as a whole can be displayed in a segmented, controlled lighting state; or all strip display areas can be lit, and the OLED turn signal as a whole can be displayed in a fully lit state; in addition, the spaced strip display areas can be controlled to light up in a certain order to create a flowing turn signal display effect.
