Description

Technical Field

[0001] This application relates to the field of vehicle equipment technology, and more particularly to a turn signal and a vehicle. Background Technology

[0002] Automotive turn signals have minimum viewing angle requirements, requiring a certain light intensity in a 45° (15° above and 15° below) direction inside the vehicle. To meet regulatory requirements, viewing angle patterns with optical refraction and reflection effects can be designed on the surface of the external lens to refract or reflect light to the specified angle.

[0003] However, the visible patterns in the aforementioned technologies can cause flow marks on the outer surface of the lens, affecting its aesthetics and the uniformity of the emitted light. Utility Model Content

[0004] In view of this, the present application provides a reflective ambient light and vehicle to solve the technical problem in the above-mentioned related technologies that visible patterns can cause flow marks on the outer surface of the lens, affecting aesthetics and the uniformity of emitted light.

[0005] To achieve the above objectives, the technical solution of this application embodiment is implemented as follows:

[0011] This application provides a turn signal that achieves efficient light utilization by setting a visually appealing pattern on the side of the decorative frame. Compared to adding patterns to the surface of the lens, the pattern on the side of the decorative frame does not affect the uniformity of frontal light and does not form flow marks on the surface of the lens that would affect the appearance of the turn signal, thus improving the aesthetics of the turn signal.

[0012] Furthermore, since the visible pattern is set on the side of the trim frame, which is closer to the side of the vehicle than the rear, the visible pattern can be prevented from being seen from the rear of the vehicle, thus improving the aesthetics of the rear of the vehicle.

[0014] The stepped structure includes a connected stepped surface and a supporting surface, wherein the supporting surface intersects with the stepped surface, the stepped surface is a refractive surface, and the supporting surface is a total reflection surface;

[0015] The refractive surface is used to refract the light emitted by the light-emitting component to the total reflection surface, and the total reflection surface is used to reflect the light to the preset angle.

[0016] In some embodiments of this application, the visible pattern includes multiple stepped structures, which are sequentially connected along a first direction to form a stepped column.

[0017] In some embodiments of this application, the visible pattern includes multiple stepped columns, and the multiple stepped columns are arranged along a second direction;

[0018] Wherein, the first direction intersects with the second direction.

[0019] In some embodiments of this application, along the second direction, the width of the step surface in the plurality of step columns gradually decreases along the first direction.

[0020] In some embodiments of this application, the height of the support surface in the plurality of step columns gradually decreases along the second direction.

[0042] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the specific technical solutions of this application will be further described in detail below with reference to the accompanying drawings of the embodiments of this application. The following embodiments are used to illustrate this application, but are not intended to limit the scope of this application.

[0043] In the embodiments of this application, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Therefore, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of the embodiments of this application, unless otherwise stated, "multiple" means two or more.

[0044] Furthermore, in the embodiments of this application, directional terms such as "upper," "lower," "left," and "right" are defined relative to the positions in which the components are schematically placed in the accompanying drawings. It should be understood that these directional terms are relative concepts, used for relative description and clarification, and can change accordingly depending on the position of the components in the accompanying drawings.

[0045] In the embodiments of this application, unless otherwise explicitly specified and limited, the term "connection" should be interpreted broadly. For example, "connection" can mean a fixed connection, a detachable connection, or an integral part; it can mean a direct connection or an indirect connection through an intermediate medium.

[0046] In embodiments of this application, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus. Without further limitation, an element defined by the phrase "comprising one..." does not exclude the presence of other identical elements in the process, method, article, or apparatus that includes that element.

[0047] In the embodiments of this application, the terms "exemplary" or "for example" are used to indicate that something is an example, illustration, or description. Any embodiment or design that is described as "exemplary" or "for example" in the embodiments of this application should not be construed as being more preferred or advantageous than other embodiments or design. Specifically, the use of the terms "exemplary" or "for example" is intended to present the relevant concepts in a specific manner.

[0048] The viewing angle patterns in the aforementioned technologies can cause flow marks on the outer surface of the lens, affecting its aesthetics and the uniformity of emitted light. This problem arises because the viewing angle patterns are located on the outer surface of the lens, which can lead to flow marks or dust accumulation in rainy weather, causing the lens surface to become blurry and consequently affecting the aesthetics of the turn signals.

[0049] The visible pattern is located on the surface of the turn signal lens facing the rear of the vehicle. Users can easily see this pattern from behind, thus affecting the aesthetics of the turn signal. Furthermore, the light emitted from the visible pattern can cause glare on the lens, resulting in uneven brightness and darkness on the lens surface, which can cause eye discomfort and negatively impact the user experience.

[0050] In addition, most of the visible patterns in related technologies are diamond patterns. Diamond patterns refract some light to the target direction, but the uncontrollable light scattering angle leads to insufficient utilization of effective light flux, which is not conducive to the turn signal emitting light at an inner 45° angle.

[0051] To address the aforementioned issues, this application provides a turn signal and vehicle. By incorporating a visually appealing pattern on the side of the decorative frame, this solution achieves efficient light utilization. Compared to adding patterns to the surface of the lens, the pattern on the side of the decorative frame does not affect the uniformity of frontal light and does not create flow marks on the lens surface that would affect the appearance of the turn signal, thus improving its aesthetics.

[0052] Furthermore, since the visible pattern is set on the side of the trim frame, which is closer to the side of the vehicle than the rear, the visible pattern can be prevented from being seen from the rear of the vehicle, thus improving the aesthetics of the rear of the vehicle.

[0053] The turn signals and vehicles provided in this application will now be described with reference to the accompanying drawings and specific embodiments.

[0054] Reference Figure 1 and Figure 2 This application provides a turn signal, which may include a lens 100, a decorative frame 200, a viewing pattern 300, and a light-emitting component 400.

[0055] The light distribution lens 100 may include a first surface 110 and a second surface 120 opposite each other along the wall thickness direction, with the first surface 110 facing outwards from the turn signal. Specifically, the light distribution lens 100 may be made of a transparent or translucent material for transmitting and scattering light.

[0056] A decorative frame 200 is disposed on the second surface 120. The decorative frame 200 may include a main body 210 and a side portion 220 connected to each other. The main body 210 faces the rear of the vehicle, and the side portion 220 faces the outer side of the vehicle. The decorative frame 200 may also be made of a transparent or translucent material that can transmit or scatter light. Alternatively, the decorative frame 200 may also be used to support optical structures.

[0057] A viewing pattern 300 is disposed on the side 220 of the decorative frame 200. The viewing pattern 300 is used to direct light to a preset angle, specifically by adjusting the light path through refraction and total internal reflection to meet regulatory requirements for light intensity distribution. The viewing pattern 300 can be disposed on the decorative frame 200 and can be a light-transmitting structure. The decorative frame 200 and the viewing pattern 300 can be a single integrated structure, formed by injection molding. The viewing pattern 300 can be formed on the surface of the side 220 of the decorative frame 200 using laser engraving technology.

[0058] The light-emitting component 400 is disposed on the side of the decorative frame 200 facing away from the lens 100. The light-emitting component 400 is used to emit light to the decorative frame 200 and the lens 100.

[0059] In practice, the light emitted by the light-emitting component 400 first illuminates the decorative frame 200. The side 220 of the decorative frame 200 is provided with a viewing angle pattern 300, which, through a specific structural design, refracts or reflects the incident light to a preset angle. This preset angle is typically to meet the regulatory requirement of a 45° viewing angle from the inside of the vehicle. Because the viewing angle pattern 300 is located on the side 220 of the decorative frame 200, rather than on the surface of the traditional lens 100, it does not affect the appearance or light uniformity of the lens 100.

[0060] This application provides a turn signal that achieves efficient light utilization by providing a viewing pattern 300 on the side 220 of the decorative frame 200. Compared to adding a pattern to the surface of the lens 100, the pattern on the side 220 of the decorative frame 200 does not affect the uniformity of the frontal light and does not form flow marks on the surface of the lens 100 that would affect the appearance of the turn signal, thus improving the aesthetics of the turn signal.

[0061] Furthermore, since the visible pattern 300 is located on the side 220 of the decorative frame 200, the side 220 is closer to the side of the vehicle than the rear of the vehicle, thus preventing the visible pattern 300 from being seen from behind the vehicle and improving the aesthetics of the rear of the vehicle.

[0062] Reference Figure 2 , Figure 3 and Figure 4 In some embodiments, the viewable pattern 300 may include a stepped structure 310. The stepped structure 310 may include a connected stepped surface 311 and a supporting surface 312, with the supporting surface 312 intersecting the stepped surface 311. The stepped surface 311 is a refractive surface, and the supporting surface 312 is a total reflection surface. The refractive surface is used to refract the light emitted by the light-emitting component 400 to the total reflection surface, and the total reflection surface is used to reflect the light to a preset angle.

[0063] The stepped surface 311 receives incident light from the light-emitting element and changes the direction of light propagation through refraction, causing it to enter the supporting surface 312 at a specific incident angle. The supporting surface 312 redirects the light to a preset angle range through total internal reflection, achieving secondary adjustment of the light path. The positional relationship between the stepped surface 311 and the supporting surface 312 satisfies the condition that the incident angle of the light is greater than the critical angle of total internal reflection, ensuring the stability of the total internal reflection process.

[0064] Specifically, the light emitted by the light-emitting element first illuminates the stepped surface 311, which deflects the light to the supporting surface 312 according to the law of refraction. Since the supporting surface 312 and the stepped surface 311 form a specific angle, the light satisfies the condition of total internal reflection at the supporting surface 312 and is then reflected to a preset angle direction.

[0065] In this way, the stepped structure 310 design allows light to be accurately directed to a preset angle after refraction and total reflection, avoiding light scattering and loss. Meanwhile, since the viewing angle pattern 300 is located on the side 220 of the decorative frame 200, it does not affect the aesthetics of the turn signal's front. Furthermore, this solution eliminates the need for additional compensation lights, reducing costs and simplifying the structure.

[0066] Reference Figure 2 , Figure 3 and Figure 4 In some embodiments, the viewable pattern 300 may include a plurality of stepped structures 310, and the plurality of stepped structures 310 may include those along a first direction (e.g., Figure 3 Connect them sequentially in the X direction to form a stepped column 320.

[0067] Multiple step structures 310 extend in a linear arrangement along a single direction, forming a continuously distributed step array 320. The extension direction of the step array 320 can be parallel to the vehicle's height or width direction. Each step structure 310 includes a refractive surface and a total reflection surface, and adjacent step structures 310 are connected by a support surface 312 or a transition surface. For example, the extension direction of the step array 320 is consistent with the outward direction of the vehicle.

[0068] When light from the light-emitting component 400 enters the stepped array 320, the light is first refracted at the refractive surface of the first stepped structure 310, and then reflected to a preset angle by the total reflection surface. The remaining light that is not reflected by the total reflection surface continues to enter the next stepped structure 310, repeating the refraction and reflection process. Through the cascading effect of multiple stepped structures 310, the light is guided to the preset angle step by step at multiple positions, effectively expanding the light coverage area and improving the uniformity of light intensity.

[0069] This application achieves an orderly arrangement of the visible pattern 300, improving the efficiency of light refraction and reflection. Because multiple stepped structures 310 are sequentially connected along a first direction to form a stepped array 320, light can propagate along a predetermined path, thereby more precisely controlling the light emission direction. This structural design helps guide more light to a preset angle, improving the visibility of the turn signal at that angle. Simultaneously, the structure of the stepped array 320 is easy to manufacture and process, allowing for mass production through methods such as mold forming, thus improving production efficiency. Furthermore, the design of the stepped array 320 can be flexibly adjusted according to actual needs, for example, by changing the number, size, or arrangement of the stepped structures 310 to adapt to the turn signal requirements of different vehicle models or different locations.

[0070] Reference Figure 2 , Figure 3 and Figure 4 In some embodiments, the viewable pattern 300 may include a plurality of step columns 320, the plurality of step columns 320 being along a second direction (e.g., Figure 3 Arranged in the Y direction. The first direction intersects with the second direction.

[0071] The first direction can be defined as the extension direction of a single step structure 310 in the step column 320, and the second direction can be defined as the arrangement direction of multiple step columns 320. The first and second directions form a spatially intersecting layout, creating a three-dimensional arrangement structure. The second direction can be the height direction of the vehicle.

[0072] Thus, through the above technical solution, this application achieves the arrangement of multiple stepped columns 320, increasing the coverage area of ​​the viewable pattern 300. The arrangement of multiple stepped columns 320 also makes the light distribution more uniform, avoiding the problem of excessively high or low brightness in some areas. By increasing the coverage area, multiple stepped columns 320 can further improve the probability of viewing the angle of sight and increase the coverage area of ​​light.

[0073] Furthermore, the multiple stepped rows 320 arranged along the vehicle height direction can adapt to the viewing needs of observers at different heights, improving the practicality and safety of the turn signals.

[0074] Reference Figure 2 , Figure 3 and Figure 4 In some embodiments, along the second direction, the width of the step surface 311 in the plurality of step rows 320 gradually decreases along the first direction.

[0075] The gradient design of the support surface 312, whose height decreases along the second direction, is based on the light emission requirements of different areas in the vehicle height direction. The height of the support surface 312 in each step column 320 is matched according to the target reflection angle at the corresponding position. The height of the support surface 312 is determined through geometric calculations, and the specific value range is set according to the reflection law of the total reflection surface and the preset angle requirements.

[0076] Through the above technical solution, this application achieves a gradual change in the width of the step surface 311 along the second direction, which makes the refraction effect of light different at different positions, and improves the forward light emission effect while ensuring that the light from the forward light source meets the minimum lateral emission angle intensity after refraction, thus achieving uniformity of light intensity distribution.

[0077] Reference Figure 2 , Figure 3 and Figure 4 In some embodiments, along the second direction, the height of the support surface 312 in the plurality of step rows 320 gradually decreases.

[0078] The design of the support surface 312, with its height gradually decreasing along the second direction, is based on the adjustment requirements of the total internal reflection path. In the arrangement direction of the stepped array 320, the reduction in the height of the support surface 312 corresponds to the reduction in the width of the stepped surface 311. By adjusting the height of the reflective surface in a stepped manner, the divergence angle of the total internal reflection light is controlled. This ensures that the light from the forward light source, after refraction, meets the minimum lateral emission angle intensity while improving the forward light emission effect and achieving uniform light intensity distribution.

[0079] Reference Figure 2 and Figure 3 In some embodiments, multiple steps 320 are arranged along the height direction of the vehicle.

[0080] The vehicle height direction refers to the vertical direction perpendicular to both the vehicle's direction of travel and its lateral direction. Multiple step rows 320 are arranged longitudinally in this direction, each step row 320 comprising step structures 310 sequentially connected along the first direction. The width of the step surfaces 311 and the height of the support surfaces 312 of adjacent step rows 320 decrease along the height direction. The longitudinal distribution of the step rows 320 allows light to form a continuous coverage in the vertical direction.

[0081] In practical implementation, when the light emitted by the light-emitting component 400 enters the side 220 of the decorative frame 200, the stepped array 320 arranged along the vehicle height direction forms a vertical optical control structure. The stepped surface 311 of each stepped array 320 refracts the incident light to the corresponding supporting surface 312, and the supporting surface 312 diffuses the light outward through total internal reflection. Since the width of the stepped surface 311 and the height of the supporting surface 312 decrease along the height direction, the stepped array 320 closer to the top of the vehicle processes a smaller incident angle of light, and the stepped array 320 closer to the bottom processes a larger incident angle of light.

[0082] Through the above technical solution, this application achieves a uniform distribution of turn signal light rays along the vehicle height direction. By arranging multiple stepped rows 320 along the vehicle height direction, compared to arranging multiple stepped rows 320 along the vehicle width direction, it is possible to avoid the visible pattern 300 occupying too much lateral space of the decorative frame 200. This allows the visible pattern 300 to be closer to the side 220 of the decorative frame 200, further reducing the probability of the visible pattern 300 being seen at the rear of the vehicle, thereby improving the aesthetics of the vehicle's rear.

[0083] In some of the solutions described above in this application, the light-emitting component 400 of the turn signal emits light directly to the decorative frame 200 and the lens 100. However, the light is scattered or diffused during transmission, resulting in uneven distribution of light received by the viewing angle pattern 300 and the lens 100, which affects the light intensity and the consistency of the lighting effect.

[0084] Reference Figure 1 In some embodiments, the turn signal may also include a thick-walled light guide 500 for directing light emitted from the light-emitting component 400 onto the viewing angle pattern 300 and the lens 100.

[0085] The thick-walled light guide 500 is made of transparent or semi-transparent material and is located on the side of the decorative frame 200 facing away from the light distribution lens 100 and aligned with the optical axis of the light-emitting component 400. The thick-walled light guide 500 can be detachably connected to the decorative frame 200, which facilitates the individual disassembly and maintenance of the thick-walled light guide 500 and reduces the maintenance cost of the turn signal.

[0086] This application achieves directional distribution and uniform diffusion of light. The light from the light-emitting component 400 is efficiently guided to the viewing angle pattern 300 and the lens 100 through the thick-walled light guide 500, reducing light energy loss and effectively avoiding dark area problems caused by light path dispersion.

[0087] Reference Figure 1In some embodiments, the light-emitting component 400 may include a circuit board 410 and a light-emitting diode 420. The circuit board 410 is disposed on the wall-thickness light guide 500, and the light-emitting diode 420 is disposed on the circuit board 410, emitting light into the wall-thickness light guide 500. The light-emitting diode 420 can be soldered onto the circuit board 410. The combined structure of the light-emitting component 400, consisting of the light-emitting diode 420 and the circuit board 410, can be detachably connected to the wall-thickness light guide 500, allowing for individual disassembly and maintenance of the circuit board 410 and the light-emitting diode 420, reducing the maintenance cost of the turn signal.

[0088] The LED 420 boasts high luminous efficiency, consuming only about 1 / 10 the power of traditional halogen lamps, effectively saving energy in automobiles. The LED 420's spectrum contains no ultraviolet or infrared radiation, generates little heat, is recyclable, and does not contain harmful substances such as mercury, making it a green lighting source. The LED 420 can be encapsulated in resin, resulting in a simple structure, excellent impact and shock resistance, and resistance to breakage, allowing it to adapt to various harsh environments and thus improving the durability and lifespan of turn signals.

[0089] Reference Figure 1 This application also provides a vehicle, which may include the turn signals described above.

[0090] By using the above-mentioned technical solution, this application can avoid flow marks and uneven light emission on the outer surface of the turn signal lens 100 without the need for an external compensation lamp or additional patterns on the surface of the lens 100. This is achieved by setting the visible pattern 300 on the side 220 of the decorative frame 200, thereby improving the vehicle's aesthetics and making the light emitted by the vehicle more uniform.

[0091] In some embodiments, the vehicle may be a gasoline-powered vehicle, or it may be a new energy vehicle, such as a pure electric vehicle (PEV / BEV), a range-extended electric vehicle (REEV), a hybrid electric vehicle (HEV), or a fuel cell electric vehicle. The vehicle may also be any vehicle equipped with a battery.

[0092] The sequence numbers of the embodiments in this application are for descriptive purposes only and do not represent the superiority or inferiority of the embodiments. The above are merely preferred embodiments of this application and do not limit the patent scope of this application. Any equivalent structural or procedural transformations made based on the content of this application's specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this application.
