Description

Technical Field

[0001] This application relates to the field of automotive lighting technology, and in particular to a vehicle cornering light assembly and a vehicle using the vehicle cornering light assembly. Background Technology

[0002] The corner lights in a vehicle are key components that provide auxiliary lighting for road corners, sides, or rear of the vehicle. Their performance directly affects the clarity of road condition observation during driving and is of great significance to ensuring driving safety.

[0003] In related technologies, corner lights typically include a light-emitting diode (LED) light source, an inner lens for light control, and a heat sink for heat dissipation. The inner lens is mainly responsible for refracting or reflecting the light emitted by the LED light source to form the desired lighting beam, while the heat sink conducts heat through indirect contact with the LED light source. The components are combined through a specific assembly structure to form a complete corner light device.

[0004] However, the aforementioned corner light structure can easily cause some light rays to fail to propagate along the expected path, resulting in stray light that interferes with the driver's normal perception of road lighting. At the same time, the light source position may deviate during the assembly process, affecting the stability of the lighting effect. Utility Model Content

[0005] This application provides a vehicle cornering light assembly and a vehicle. The vehicle cornering light assembly can not only reduce the formation of stray light, but also avoid deviations in the position of the light source to a certain extent, thereby improving the stability of the lighting effect.

[0006] On one hand, this application provides a vehicle cornering light assembly, including a radiator, a circuit board assembly, and an inner lens; the radiator is used to connect to the vehicle body; the circuit board assembly includes a circuit board and a light source, the circuit board is disposed on the radiator, and the light source is disposed on the side of the circuit board away from the radiator; the inner lens is disposed on the circuit board, the light source faces the inner lens, and the inner lens, the circuit board, and the radiator are connected together; wherein, the inner lens has an incident surface, the incident surface is formed with a plurality of sawtooth structures connected together, the sawtooth structure includes a first tooth surface and a second tooth surface connected together, the first tooth surface is connected to the rear side of the second tooth surface, the angle between the first tooth surface and the vertical plane is greater than or equal to 12 degrees and less than or equal to 25 degrees, and the angle between the second tooth surface and the vertical plane is greater than or equal to 35 degrees and less than or equal to 50 degrees.

[0007] In the vehicle cornering light assembly provided in this application, by limiting the tilt angle of the first and second tooth surfaces, the assembly can redirect light that might otherwise be refracted downwards to non-target areas on the ground, instead refracting it upwards and creating a diffusion effect. This reduces stray light reaching areas outside the intended ground location, while the diffusion effect weakens the light intensity and guides it towards the sky. This not only avoids interference from ground stray light on the driver's vision to a certain extent, but also prevents new light pollution caused by direct glare into the sky, thus improving the purity of road lighting. Moreover, in the vehicle corner light assembly provided in this application, the relative position of the light source and the inner lens is strictly fixed, which reduces the assembly deviation caused by the indirect connection of components in related technologies, and ensures that the light can always be refracted along the preset path of the sawtooth structure, providing a basic guarantee for stray light control and the stability of the lighting effect.

[0008] Furthermore, by eliminating stray ground light and stabilizing the position of the light source, the upwardly refracted diffused light can more evenly cover the wide-angle area in front of the vehicle's sides, forming a wider effective lighting range in conjunction with the main lighting. This meets the development needs of automotive lighting technology for wide-area, clean road surface illumination, enhancing the auxiliary lighting value of the vehicle cornering light assembly provided in this application under complex road conditions and adding multiple layers of protection for driving safety.

[0009] As an optional implementation, the light emission direction of the light source is consistent with the orientation of the inner lens, and the angle between the light emission direction of the light source and the front-rear direction of the vehicle is 45 degrees.

[0010] Since the light source's emission direction is consistent with the orientation of the inner lens, it ensures that the light emitted by the light source can reach the incident surface of the inner lens to the maximum extent, reducing light loss during propagation, improving light utilization, and allowing more light to be refracted and controlled through the first and second tooth surfaces of the sawtooth structure.

[0011] Meanwhile, the 45-degree angle setting is compatible with the road widening function that the vehicle corner light assembly provided in this application needs to achieve. This allows the light that is refracted by the inner lens and diffused upwards to more accurately cover the corner area in front of the vehicle's side, forming an effective connection with the main lighting in the front and rear directions of the vehicle. This not only avoids blind spots to a certain extent, but also enhances the supplementary lighting effect at road corners through directional light distribution. Combined with the elimination of stray light by the sawtooth structure, the light distribution of the entire lighting area is more in line with actual driving needs, further improving the reliability of the auxiliary lighting of the vehicle corner light assembly provided in this embodiment.

[0012] As an optional implementation, the heat sink includes a base and a plurality of spaced-apart heat dissipation fins, the plurality of heat dissipation fins being disposed on the side of the base away from the circuit board; the inner lens includes a bracket and a lens body connected to the bracket, the incident surface being formed on the lens body; wherein, the base, the circuit board and the bracket are connected together.

[0013] By setting multiple heat dissipation fins, the contact area between the heat sink and the air can be increased, accelerating the dissipation of heat conducted from the base, ensuring that the light source on the circuit board maintains a suitable temperature during operation, and avoiding the impact of overheating on luminous efficiency and lifespan.

[0014] The inner lens is connected to the base and circuit board via a bracket, which not only makes the position of the lens body more stable and ensures that the sawtooth structure of the incident surface is always accurately aligned with the light emission direction of the light source, thus guaranteeing the stability of the light refraction effect, but also further enhances the overall rigidity of the vehicle corner light assembly provided in this embodiment, reducing component displacement caused by vibration during vehicle operation. This allows the light emitted by the light source to continuously and stably achieve the functions of eliminating stray light and widening road lighting after being refracted by the lens body.

[0015] As an optional implementation, the vehicle corner light assembly provided in this application further includes a first fastener; a first connecting hole is provided on the base, a second connecting hole is provided on the circuit board, the second connecting hole is opposite to the first connecting hole, and a third connecting hole is provided on the bracket, the third connecting hole is opposite to the second connecting hole; wherein, the first fastener passes through the third connecting hole, the second connecting hole and the first connecting hole in sequence to connect the base, the circuit board and the bracket together.

[0016] The first fastener passes through the third connecting hole, the second connecting hole, and the first connecting hole in sequence, which can tightly and firmly connect the base, circuit board, and bracket together. This can, to a certain extent, prevent the components from loosening or relative displacement due to vibration and other factors during vehicle operation, thereby ensuring that the relative position of the light source and the lens body remains accurate. This ensures that the sawtooth structure of the incident surface can stably refract and control the light emitted by the light source, maintaining the effect of eliminating stray light and widening the road surface lighting.

[0017] As an optional implementation, the vehicle corner light assembly provided in this application further includes a second fastener; the base is provided with a connecting protrusion, the connecting protrusion has a first fastening hole, and the circuit board has a clearance notch for the connecting protrusion to pass through; the bracket is provided with a second fastening hole, the second fastening hole being opposite to the first fastening hole; wherein, the second fastener passes through the second fastening hole and the first fastening hole in sequence to connect the bracket and the base together.

[0018] This not only ensures that the light emitted by the light source is continuously and accurately directed onto the incident surface of the lens body, guaranteeing the stable refraction control effect of the sawtooth structure and maintaining the performance of eliminating stray light and widening the road surface lighting, but also complements the connection method of the first fastener, further reducing the risk of assembly errors and component loosening, and providing a more comprehensive guarantee for the long-term stable operation of the vehicle corner light assembly provided in this application.

[0019] As an optional implementation, the vehicle corner light assembly provided in this application further includes a first positioning structure and a second positioning structure. The first positioning structure is used to define the mounting position of the circuit board assembly, and the second positioning structure is used to define the mounting position of the inner lens.

[0020] The first positioning structure is specifically designed to define the installation position of the circuit board assembly. It provides clear positioning guidance when assembling the circuit board and the base. Combined with the positioning method of the connecting protrusion passing through the avoidance notch, it doubles the accuracy of the circuit board's position, preventing it from being skewed during assembly. This ensures that the light source on the circuit board can be accurately aligned with the incident surface of the lens body, laying the foundation for the effective refraction of light.

[0021] The second positioning structure limits the installation position of the inner lens and plays a precise guiding role when the bracket is connected to the base. It corresponds to the alignment requirements of the first and second fastening holes, ensuring that the serrated structure of the lens body can match the light emission direction of the light source, making the light refraction control effect more stable.

[0022] As an optional implementation, the first positioning structure includes a first positioning post and a first positioning hole is provided on the circuit board; wherein the first positioning post extends into the first positioning hole.

[0023] The cooperation between the first positioning post and the first positioning hole provides a precise installation reference for the circuit board, which can effectively constrain the position of the circuit board in the early stage of assembly, prevent it from shifting during the subsequent fastening process, and ensure that the light source on the circuit board can always be accurately aligned with the incident surface of the lens body. Combined with the positioning function of the connecting protrusion passing through the avoidance notch, it forms a multi-position guarantee for the circuit board, creating favorable conditions for the stable refraction of light.

[0024] As an optional implementation, the second positioning structure includes a second positioning post, a second positioning hole on the circuit board, and a third positioning hole on the bracket, with the third positioning hole opposite to the second positioning hole; wherein the second positioning post passes through the second positioning hole and extends into the third positioning hole.

[0025] In this way, not only can the bracket drive the lens body to be accurately installed in place, ensuring that the serrated structure of the incident surface matches the light emission direction of the light source, but it can also be combined with the fastening effect of the first fastener and the second fastener to further reduce assembly errors, so that the vehicle corner light assembly provided in this application can continuously and stably perform the functions of eliminating stray light and widening the road surface, thereby improving the reliability of the overall structure.

[0026] As an alternative implementation, the base includes a main body and a connecting part, with the connecting part connected to the side of the main body; wherein, a plurality of heat dissipation fins are disposed on the side of the main body away from the circuit board, and the connecting part is used for detachable connection with the vehicle body.

[0027] The main body serves as the support for the heat dissipation fins. Multiple heat dissipation fins are concentrated on the side of the main body away from the circuit board, which makes the heat dissipation area more concentrated. This facilitates the rapid conduction of heat from the circuit board through the main body to the heat dissipation fins. Combined with the spaced arrangement of multiple heat dissipation fins, a more efficient air convection channel can be formed, which enhances the heat dissipation effect on the light source and ensures its long-term stable operation.

[0028] The connecting part is located on the side of the main body and is specifically designed for detachable connection with the vehicle body. This not only avoids interference between the heat sink fins and the connection between the base and the vehicle body to a certain extent, but also facilitates the installation, maintenance and replacement of the vehicle corner light assembly provided in this application through the detachable connection method. At the same time, the side connection method allows the main body to be closer to the circuit board, reducing the heat conduction path and further improving the heat dissipation efficiency.

[0029] On the other hand, this application provides a vehicle, including a body and the aforementioned vehicle corner light assembly; wherein the radiator is detachably connected to the body.

[0030] The vehicle provided in this application has better performance and higher safety by adopting the aforementioned vehicle corner light assembly. Attached Figure Description

[0033] The technical solutions in this application will be clearly and thoroughly described below with reference to the accompanying drawings. In the description of the embodiments of this application, unless otherwise stated, " / " means "or," for example, A / B can mean A or B. "And / or" in the text is merely a description of the relationship between related objects, indicating that three relationships can exist. For example, A and / or B can represent: A existing alone, A and B existing simultaneously, and B existing alone. Furthermore, in the description of the embodiments of this application, "multiple" refers to two or more than two.

[0034] Hereinafter, the terms "first" and "second" are used for descriptive purposes only and should not be construed as implying or suggesting relative importance or implicitly indicating the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature.

[0035] In related technologies, corner lights typically include a light-emitting diode (LED) light source, an inner lens for light control, and a heat sink for heat dissipation. The inner lens is primarily responsible for refracting or reflecting the light emitted by the LED to form the desired illumination beam, while the heat sink conducts heat through indirect contact with the LED. These components are assembled using a specific assembly structure to form a complete corner light device. However, this corner light structure can easily lead to some light rays not propagating along the expected path, creating stray light that interferes with the driver's normal perception of road lighting. Furthermore, the assembly process can easily result in deviations in the light source's position, affecting the stability of the lighting effect.

[0036] Based on this, this application provides a vehicle cornering light assembly and a vehicle, wherein by forming a sawtooth structure on the surface of the inner lens, not only can stray light be reduced, but the position of the light source can also be avoided to a certain extent, thereby improving the stability of the lighting effect.

[0037] Please combine Figures 1 to 4 , Figure 1 This is a three-dimensional structural diagram of the vehicle corner light assembly provided in the embodiments of this application. Figure 2 This is a schematic diagram of the structure of the inner lens in the vehicle corner light assembly provided in this application embodiment. Figure 3 for Figure 2 Cross-sectional view along the AA direction. Figure 4 for Figure 3 A magnified view of the partial structure at point B. As shown in the figure, this embodiment provides a vehicle corner light assembly 10, including a radiator 1, a circuit board assembly 2, and an inner lens 3. The radiator 1 is used to connect to the vehicle body; the circuit board assembly 2 includes a circuit board 21 and a light source 22. The circuit board 21 is disposed on the radiator 1, and the light source 22 is disposed on the side of the circuit board 21 facing away from the radiator 1; the inner lens 3 is disposed on the circuit board 21, and the light source 22 is disposed facing the inner lens 3. The inner lens 3, the circuit board 21, and the radiator 1 are connected together; wherein, the inner lens 3 has an incident surface 31, and the incident surface 31 forms a plurality of sawtooth structures 311 connected together. The sawtooth structure 311 includes a first tooth surface 3111 and a second tooth surface 3112 connected together. The first tooth surface 3111 is connected to the rear side of the second tooth surface 3112. The angle between the first tooth surface 3111 and the vertical plane is greater than or equal to 12 degrees and less than or equal to 25 degrees, and the angle between the second tooth surface 3112 and the vertical plane is greater than or equal to 35 degrees and less than or equal to 50 degrees.

[0038] Figure 5This is a light direction diagram of the inner lens in the vehicle cornering light assembly provided in this embodiment. The dotted lines and arrows indicate the direction of light illumination. By limiting the tilt angles of the first tooth surface 3111 and the second tooth surface 3112, the vehicle cornering light assembly 10 provided in this embodiment can redirect light that might otherwise be refracted downwards to non-target areas on the ground, instead refracting it upwards and creating a diffusion effect. This reduces stray light illuminating locations outside the designed ground surface at the source, while simultaneously reducing light brightness and guiding it towards the sky through diffusion. This avoids interference from ground stray light on the driver's vision to a certain extent, and prevents new light pollution caused by strong light directly hitting the sky, thus improving the purity of road lighting. Moreover, in the vehicle corner light assembly 10 provided in this embodiment, the relative positions of the light source 22 and the inner lens 3 are strictly fixed, which reduces the assembly deviation caused by the indirect connection of components in related technologies, and ensures that the light can always be refracted along the preset path of the sawtooth structure 311, providing a basic guarantee for stray light control and the stability of the lighting effect.

[0039] Furthermore, by eliminating stray ground light and stabilizing the position of the light source, the upwardly refracted diffused light can more evenly cover the wide-angle area in front of the vehicle's sides, forming a wider effective lighting range in conjunction with the main lighting. This meets the development needs of vehicle lighting technology for wide-area, clean road surface illumination, enhancing the auxiliary lighting value of the vehicle corner light assembly 10 provided in this embodiment under complex road conditions and adding multiple layers of protection for driving safety.

[0040] It should be noted that in some specific embodiments, the inner lens 3 is made of high-temperature polymethyl methacrylate (PMMA). Of course, in other embodiments, the inner lens 3 may also be made of other materials. No limitation is made here.

[0041] The angle between the first tooth surface 3111 and the vertical plane can be 12, 13, 14, 15, 16, 17, 18, 19, 20, 21, 22, 23, 24, or 25 degrees; the angle between the second tooth surface 3112 and the vertical plane can be 35, 36, 37, 38, 39, 40, 41, 42, 43, 44, 45, 46, 47, 48, 49, or 50 degrees. No specific limitations are imposed on the angle values ​​between the first tooth surface 3111 and the vertical plane, or between the second tooth surface 3112 and the vertical plane.

[0042] In this embodiment, a plurality of sawtooth structures 311 are formed on the incident surface 31. For each sawtooth structure 311, the angle between the first tooth surface 3111 and the vertical surface can be equal or unequal, and the angle between the second tooth surface 3112 and the vertical surface can be equal or unequal.

[0043] Furthermore, in some embodiments, the light source 22 described above can be an LED lamp. Here, there is no specific limitation on the type of light source 22.

[0044] Please continue to combine Figure 6 , Figure 6 This is a schematic diagram of the planar structure of the vehicle corner light assembly provided in this application embodiment. To meet relevant regulatory requirements, the light emission direction of the light source 22 is consistent with the orientation of the inner lens 3, and the angle between the light emission direction of the light source 22 and the vehicle's longitudinal direction is 45 degrees. Because the light emission direction of the light source 22 is consistent with the orientation of the inner lens 3, it ensures that the light emitted by the light source 22 can reach the incident surface 31 of the inner lens 3 to the maximum extent, reducing light loss during propagation, improving light utilization, and allowing more light to be refracted and controlled through the first tooth surface 3111 and the second tooth surface 3112 of the sawtooth structure 311.

[0045] Meanwhile, the 45-degree angle setting is compatible with the road widening function that the vehicle corner light assembly 10 provided in this embodiment needs to achieve. This allows the light that is refracted by the inner lens 3 and diffused upward to more accurately cover the corner area in front of the vehicle's side, forming an effective connection with the main lighting in the front and rear directions of the vehicle. This not only avoids blind spots to a certain extent, but also enhances the supplementary lighting effect at road corners through directional light distribution. Combined with the elimination of stray light by the sawtooth structure 311, the light distribution of the entire lighting area is more in line with actual driving needs, further improving the reliability of the auxiliary lighting of the vehicle corner light assembly 10 provided in this embodiment.

[0046] Please continue to combine Figure 7 and Figure 8 , Figure 7 This is an exploded view of the vehicle corner light assembly provided in the embodiments of this application. Figure 8 for Figure 7 A structural schematic diagram from another perspective. As shown in the figure, in some optional embodiments, the heat sink 1 includes a base 11 and a plurality of spaced-apart heat dissipation fins 12, the plurality of heat dissipation fins 12 being disposed on the side of the base 11 facing away from the circuit board 21; the inner lens 3 includes a bracket 32 ​​and a lens body 33 connected to the bracket 32, the incident surface 31 being formed on the lens body 33; wherein, the base 11, the circuit board 21 and the bracket 32 ​​are connected together.

[0047] By setting multiple heat dissipation fins 12, the contact area between the heat sink 1 and the air can be increased, the heat conducted from the base 11 can be dissipated faster, and the light source 22 on the circuit board 21 can be kept at a suitable temperature during operation, so as to avoid affecting the luminous efficiency and service life due to overheating.

[0048] The inner lens 3 is connected to the base 11 and the circuit board 21 via the bracket 32. This not only makes the position of the lens body 33 more stable, ensuring that the sawtooth structure 311 of the incident surface 31 can always be accurately aligned with the light emission direction of the light source 22, thus guaranteeing the stability of the light refraction effect, but also further strengthens the overall rigidity of the vehicle corner lamp assembly 10 provided in this embodiment, reducing the displacement of components caused by vibration during vehicle operation. As a result, the light emitted by the light source 22 can continuously and stably achieve the functions of eliminating stray light and widening road lighting after being refracted by the lens body 33. Specifically, the base 11 includes a main body 111 and a connecting part 112, with the connecting part 112 connected to the side of the main body 111; wherein, a plurality of heat dissipation fins 12 are disposed on the side of the main body 111 away from the circuit board 21, and the connecting part 112 is used for detachable connection with the vehicle body.

[0049] The main body 111 serves as the supporting base for the heat dissipation fins 12. Multiple heat dissipation fins 12 are concentrated on the side of the main body 111 away from the circuit board 21, which can make the heat dissipation area more concentrated and facilitate the rapid conduction of heat from the circuit board 21 to the heat dissipation fins 12 through the main body 111. With the spaced arrangement of multiple heat dissipation fins 12, a more efficient air convection channel can be formed, which can enhance the heat dissipation effect on the light source 22 and ensure its long-term stable operation.

[0050] The connecting part 112 is connected to the side of the main body 111 and is specifically designed for detachable connection with the vehicle body. This not only avoids interference between the setting of the heat dissipation fins 12 and the connection between the base 11 and the vehicle body to a certain extent, but also provides convenience for the installation, maintenance and replacement of the vehicle corner light assembly 10 provided in this embodiment through the detachable connection method. At the same time, the side connection method allows the main body 111 to be closer to the circuit board 21, reducing the heat conduction path and further improving the heat dissipation efficiency.

[0051] To achieve a detachable connection between the connecting part 112 and the vehicle body, in some optional embodiments, the connecting part 112 is provided with a fixing hole 1121, through which threaded fasteners such as screws can pass to connect to the vehicle body. It is understood that, to improve the connection reliability between the vehicle corner light assembly 10 and the vehicle body provided in this embodiment, multiple spaced connecting parts 112 can be provided on the outer periphery of the main body 111. Here, the number of connecting parts 112 is not limited.

[0052] Please continue to combine Figure 9 , Figure 9 for Figure 1 A three-dimensional structural diagram from another perspective. To connect the base 11, circuit board 21, and bracket 32 ​​together, the vehicle corner light assembly 10 provided in this embodiment also includes a first fastener (not shown in the figure); a first connecting hole 1111 is provided on the main body 111, a second connecting hole 211 is provided on the circuit board 21, the second connecting hole 211 is opposite to the first connecting hole 1111, and a third connecting hole 321 is provided on the bracket 32, the third connecting hole 321 is opposite to the second connecting hole 211; wherein, the first fastener passes sequentially through the third connecting hole 321, the second connecting hole 211, and the first connecting hole 1111 to connect the base 11, circuit board 21, and bracket 32 ​​together.

[0053] The first fastener passes through the third connecting hole 321, the second connecting hole 211 and the first connecting hole 1111 in sequence, which can tightly and firmly connect the base 11, the circuit board 21 and the bracket 32 ​​together. To a certain extent, it avoids the loosening or relative displacement of components due to vibration and other factors during vehicle operation, thereby ensuring that the relative position of the light source 22 and the lens body 33 always remains accurate, and ensuring that the sawtooth structure 311 of the incident surface 31 can stably refract and control the light emitted by the light source 22, maintaining the effect of eliminating stray light and widening the road surface lighting.

[0054] Meanwhile, the above connection method makes the assembly process of heat sink 1, circuit board assembly 2 and inner lens 3 more standardized and consistent, reduces assembly errors, and further reduces the risk of position deviation of light source 22.

[0055] Furthermore, in order to improve the connection reliability between the radiator 1 and the inner lens 3, the vehicle corner light assembly 10 provided in this embodiment also includes a second fastener (not shown in the figure); the base 11 is provided with a connecting protrusion 13, the connecting protrusion 13 is provided with a first fastening hole 131, and the circuit board 21 is provided with a clearance notch 212 for the connecting protrusion 13 to pass through; the bracket 32 ​​is provided with a second fastening hole 322, the second fastening hole 322 is opposite to the first fastening hole 131; wherein, the second fastener passes through the second fastening hole 322 and the first fastening hole 131 in sequence to connect the bracket 32 ​​and the base 11 together.

[0056] By connecting the protruding post 13, a positioning reference can be provided for the circuit board 21, preventing it from shifting during assembly or use, and ensuring that the first fastening hole 131 can be precisely aligned with the second fastening hole 322. The second fastener passes through the second fastening hole 322 and the first fastening hole 131 in sequence. Based on the connection of the first fastener, the bracket 32 ​​and the base 11 are fixed from another position, forming a multi-point connection structure. This significantly enhances the vibration resistance of the vehicle corner lamp assembly 10 provided in this embodiment, ensuring that the relative positions between the lens body 33, the circuit board 21, and the base 11 remain stable.

[0057] In this way, not only can the light emitted by the light source 22 be continuously and accurately directed onto the incident surface 31 of the lens body 33, ensuring the stable refraction control effect of the sawtooth structure 311 on the light and maintaining the performance of eliminating stray light and widening the road surface lighting, but it also complements the connection method of the first fastener, further reducing the risk of assembly errors and component loosening, and providing a more comprehensive guarantee for the long-term stable operation of the vehicle corner light assembly 10 provided in this embodiment.

[0058] Understandably, since the connecting protrusion 13 has a first fastening hole 131, the structural strength of the connecting protrusion 13 may be reduced. To improve the structural strength of the connecting protrusion 13, a reinforcing plate 14 can be connected to the side of the connecting protrusion 13, and the side of the bracket 32 ​​has an insertion interface 323 for the reinforcing plate 14 to be inserted. In this way, through the cooperation of the reinforcing plate 14 and the insertion interface 323, the installation position of the inner lens 3 can also be determined, improving the assembly efficiency between the inner lens 3 and the heat sink 1.

[0059] Of course, if the mounting positions of the circuit board assembly 2 and the inner lens 3 can be determined before connecting the circuit board 21 to the base 11 and before connecting the bracket 32 ​​to the circuit board 21 and the base 11, the assembly efficiency of the vehicle corner light assembly 10 provided in this embodiment can be improved. Therefore, in some embodiments, the vehicle corner light assembly 10 provided in this embodiment further includes a first positioning structure 4 and a second positioning structure 5, wherein the first positioning structure 4 is used to define the mounting position of the circuit board assembly 2 and the second positioning structure 5 is used to define the mounting position of the inner lens 3.

[0060] The first positioning structure 4 is specifically designed to define the installation position of the circuit board assembly 2. It can provide clear positioning guidance when assembling the circuit board 21 and the base 11. Combined with the positioning method of the connecting protrusion 13 passing through the avoidance notch 212, it doubles the accuracy of the position of the circuit board 21, avoids it from being tilted during the assembly process, and ensures that the light source 22 on the circuit board 21 can be accurately aligned with the incident surface 31 of the lens body 33, laying the foundation for the effective refraction of light.

[0061] The second positioning structure 5 limits the installation position of the inner lens 3 and plays a precise guiding role when the bracket 32 ​​is connected to the base 11. It corresponds to the alignment requirements of the first fastening hole 131 and the second fastening hole 322, ensuring that the sawtooth structure 311 of the lens body 33 can match the light emission direction of the light source 22, so that the light refraction control effect is more stable.

[0062] like Figure 1 , Figures 6 to 9As shown, the first positioning structure 4 includes a first positioning post 41, and a first positioning hole 213 is provided on the circuit board 21; wherein, the first positioning post 41 extends into the first positioning hole 213.

[0063] The cooperation between the first positioning post 41 and the first positioning hole 213 provides a precise installation reference for the circuit board 21, which can effectively constrain the position of the circuit board 21 in the early stage of assembly, prevent it from shifting during the subsequent fastening process, and ensure that the light source 22 on the circuit board 21 can always be accurately aligned with the incident surface 31 of the lens body 33. Combined with the positioning function of the connecting protrusion 13 passing through the avoidance notch 212, it forms a multi-position guarantee for the circuit board 21, creating favorable conditions for the stable refraction of light.

[0064] Furthermore, the second positioning structure 5 includes a second positioning post 51, a second positioning hole 214 is provided on the circuit board 21, and a third positioning hole 324 is provided on the bracket 32, with the third positioning hole 324 being opposite to the second positioning hole 214; wherein, the second positioning post 51 passes through the second positioning hole 214 and extends into the third positioning hole 324. The second positioning post 51 passes through the second positioning hole 214 and the third positioning hole 324 in sequence, positioning and connecting the circuit board 21 and the bracket 32, making the relative positions of the inner lens 3, the circuit board assembly 2, and the heat sink 1 more stable. This not only ensures that the bracket 32 ​​drives the lens body 33 to be accurately installed, ensuring that the serrated structure 311 of the incident surface 31 matches the light emission direction of the light source 22, but also, combined with the fastening effect of the first and second fasteners, further reduces assembly errors, enabling the vehicle corner light assembly 10 provided in this embodiment to continuously and stably perform its functions of eliminating stray light and widening road surface illumination, thus improving the overall structural reliability.

[0065] When assembling the vehicle corner light assembly 10 provided in this embodiment, first connect the light source 22 and the circuit board 21 together, then connect the circuit board assembly 2 and the radiator 1 together, then connect the inner lens 3 to the circuit board assembly 2 and the radiator 1 together, and finally connect the assembled vehicle corner light assembly 10 to the vehicle body.

[0066] Please continue to combine Figure 10 and Figure 11 , Figure 10 This is a diagram of the light emitted by the vehicle cornering light assembly provided in this embodiment of the application. Figure 11 This is a light pattern diagram of a vehicle cornering light assembly provided in an embodiment of this application.

[0067] like Figure 10 As shown, the vehicle corner light assembly 10 provided in this embodiment changes the light that might originally be refracted downwards to the non-target area of ​​the ground to be refracted upwards and forms a diffusion effect.

[0068] like Figure 11 As shown, in the horizontal direction, it can be seen that the vehicle corner light assembly 10 provided in this embodiment has a wide illumination range; in the vertical direction, it can be seen that the vehicle corner light assembly 10 provided in this embodiment produces less stray light.

[0069] This embodiment also provides a vehicle, including a body and the aforementioned vehicle corner light assembly 10; wherein the radiator 1 is detachably connected to the body. It should be noted that the vehicle corner light assembly 10 and the connection method between the vehicle corner light assembly 10 and the body have been described in detail in the above embodiments, and will not be repeated here.

[0070] Of course, the vehicle provided in this embodiment should also include other modules or components, but there are no restrictions on other modules or components.

[0071] The vehicle provided in this embodiment has better performance and higher safety by adopting the above-mentioned vehicle corner light assembly 10.

[0072] The above description is merely a specific embodiment of this application, but the scope of protection of this application is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the scope of the technology disclosed in this application should be included within the scope of protection of this application. Therefore, the scope of protection of this application should be determined by the scope of the claims.
