Description

Technical Field

[0001] This application relates to the field of vehicle technology, and in particular to a vehicle lamp structure and a vehicle using the vehicle lamp structure. Background Technology

[0002] In the field of automotive lighting, crystal-clear materials, with their unique optical refraction properties, have become an important design element. The dynamic and dazzling light effects not only enhance the user's interaction with the vehicle but also improve the overall appearance of the car.

[0003] In related technologies, crystal car lights mostly adopt a backlit lighting architecture. An array of light-emitting diodes (LEDs) is placed on the back of the translucent crystal component as the basic light source. Through a precisely arranged point light source combined with a light guide structure, the light is refracted through the prism surface to form a scattered light effect. In the non-working state, the crystal shape only relies on the reflection of natural light to present a static visual effect; when the light source is activated, a dense arrangement of LED particles and multiple layers of light guide medium are required to achieve dynamic light effects such as gradient and breathing.

[0004] However, among the aforementioned headlights, the static crystal effect cannot meet users' requirements for dynamic aesthetics when not in operation, which will reduce the overall user experience of the vehicle; moreover, the realization of dynamic light effects relies on a high-density LED layout, which will not only increase material costs, but also cause light energy loss due to the multi-layer light guide structure. Utility Model Content

[0005] This application provides a vehicle headlight structure and vehicle that can improve the overall user experience of the vehicle, reduce the overall manufacturing cost of the vehicle, and reduce light energy loss to a certain extent.

[0006] On one hand, this application provides a vehicle lamp structure, including a housing assembly, a crystal module, and a light source module: the housing assembly has a mounting cavity formed inside, and the housing assembly is used to connect to the vehicle body; the crystal module is located in the mounting cavity and connected to the housing assembly, the crystal module includes a crystal element and a reflector unit, the crystal element has a prism surface and a back surface arranged opposite to each other, the prism surface faces the outside of the vehicle lamp structure, the reflector unit is arranged facing the back surface, and the reflector unit includes a plurality of spaced reflectors; the light source module is located in the mounting cavity and connected to the housing assembly, and the light source module is located above the crystal element, the light source module is capable of emitting light directed toward the prism surface; wherein, a plane passing through a horizontal line is defined as the mounting surface, each reflector has an angle with the mounting surface, and the angle formed between each reflector and the mounting surface is not equal, each reflector is capable of moving relative to the crystal element.

[0007] In the non-illuminated state, the differentiated tilt angle reflector dynamically adjusts to form a multi-level optical path interaction with the prism surface. Utilizing the disordered reflection and refraction effect of ambient light, the crystal design can present a natural and smooth flowing light effect without relying on a light source module, enhancing the visual appeal of the vehicle when stationary. When the light source is activated, the light projected from a high position is dynamically deflected by the gradient angle reflector. Combined with three-dimensional superimposed light field construction technology, a single light source achieves full coverage of the prism surface. This not only reduces the number of densely arranged LED light sources in related technologies, lowering costs, but also reduces energy loss through optical path optimization.

[0008] As an optional implementation, each reflector is rotatable relative to the crystal component; the crystal module also includes a bracket, a rotating shaft, and a drive mechanism; the bracket is connected to the housing assembly; the rotating shaft is rotatably connected to the bracket, and multiple reflectors are disposed on the rotating shaft, the axis of the rotating shaft being located on the mounting surface; the drive mechanism is used to drive the rotating shaft to rotate, thereby causing each reflector to rotate relative to the crystal component.

[0009] This ensures the spatiotemporal consistency of the motion trajectory of the mirrors mounted on the same axis. By designing the axis and the mounting surface to be coplanar, the mechanical motion is constrained within a two-dimensional plane, reducing the complexity of dynamic optical path compensation.

[0010] As an optional implementation, multiple reflector units are configured, and multiple rotating shafts are rotatably connected to the bracket, with each rotating shaft corresponding to one of the multiple reflector units. The driving mechanism includes a driving component, an active component, and a linkage unit. The driving component is connected to the bracket, the active component is connected to the driving component, and the linkage unit is connected to the active component. The linkage unit is also connected to each rotating shaft in a transmission manner. The driving component is used to drive the active component to move, and under the transmission action of the linkage unit, it drives each rotating shaft to rotate. The number of reflector units is M or N, and M is greater than N.

[0011] Thus, when the driving component drives the active component, the linkage unit synchronously distributes the power to M or N rotating shafts, so that each mirror unit can form a group motion rhythm through mechanical constraints while maintaining independent rotational degrees of freedom.

[0012] As an optional implementation, the back has a first extending direction, which is perpendicular to the axis of rotation; multiple mirror units are arranged at intervals along the first extending direction, and in the first extending direction, the rotation axis located in the middle is defined as the central rotation axis, and the rotation axes located on both sides of the central rotation axis are defined as the side rotation axes.

[0013] In this way, the vector control precision of light diffusion can be enhanced by utilizing the perpendicular relationship between the first extension direction and the axis of rotation.

[0014] As an optional implementation, the number of reflector units is M; the driving component is a drive motor, and the driving component is a drive gear, which is mounted on the output shaft of the drive motor; the linkage unit includes a first driven gear and multiple second driven gears, the first driven gear is mounted on the central rotating shaft and meshes with the drive gear; the multiple second driven gears are arranged one-to-one with multiple rotating shafts, and adjacent two second driven gears mesh with each other; on the central rotating shaft, the first driven gear and the second driven gears are spaced apart.

[0015] This allows the M mirror units to form a centrally symmetrical angular velocity distribution during rotation, and the gear spacing between the central and side shafts effectively balances the impact of transmission backlash on optical path synchronization.

[0016] As an optional implementation, the number of reflector units is N; the driving component is a push rod motor, the active component is a main connecting rod, the main connecting rod is rotatably connected to the push rod of the push rod motor, and the main connecting rod is drivenly connected to the central rotating shaft; the linkage unit includes multiple connecting rod assemblies, and the multiple connecting rod assemblies are arranged one-to-one with multiple side rotating shafts; the connecting rod assembly includes a first connecting rod and a second connecting rod that are rotatably connected, the first connecting rod is drivenly connected to the corresponding side rotating shaft, the adjacent second connecting rod is rotatably connected to the main connecting rod, and two adjacent second connecting rods are rotatably connected.

[0017] In this way, the N reflector units produce asymmetrical but synchronous angular changes within the push rod stroke.

[0018] As an optional implementation, the rotation angle of the shaft is greater than or equal to 20 degrees and less than or equal to 30 degrees.

[0019] In this way, by limiting the rotation angle of the rotating shaft, the geometric refraction characteristics of the prism surface of the crystal component can be matched, ensuring that the reflected light spot of the mirror can completely cover the effective working area of ​​the prism surface during rotation, avoiding the lag of light effect transition due to too small an angle or the edge light energy overflow caused by too large an angle.

[0020] As an optional implementation, the bracket includes a first sub-bracket and a second sub-bracket connected together, with the first sub-bracket and the second sub-bracket enclosing a mounting groove; the crystal component, the reflector unit and the rotating shaft are all disposed in the mounting groove; wherein, the mounting groove has a bottom wall facing the reflector unit, and an aluminum film is disposed on the bottom wall.

[0021] In this way, the physical boundary of the mounting slot limits the relative positional tolerance between the crystal component and the reflector unit, ensuring that the light path always maintains the preset reflection-refraction geometry during dynamic rotation. At the same time, the high reflectivity of the aluminum film suppresses the disordered diffusion of stray light in the mounting slot, thereby improving the brightness uniformity of the dynamic light effect.

[0022] As an alternative implementation, the edge of the second sub-bracket extends toward the housing assembly to cover the drive mechanism.

[0023] In this way, during the operation of the dynamic light effect, the user can only perceive the dazzling changes of the prism surface of the crystal component, while the mechanical movement of the drive mechanism is confined to an invisible area, thus improving the aesthetic performance of the headlight structure provided in this application.

[0024] As an alternative implementation, the housing assembly includes a first housing and a second housing connected together, the first housing and the second housing enclosing a mounting cavity, the first housing being used to connect to the vehicle body, the crystal module and the light source module being connected to the first housing, the second housing being disposed facing the prism surface, and the second housing being a light-transmitting component.

[0025] In this way, the enclosed mounting cavity constructed by the first and second shells can not only provide dust and shock protection for the internal optical units, but also fully preserve the dynamic and dazzling expressiveness of the crystal shape through the light-transmitting characteristics of the second shell.

[0026] On the other hand, this application provides a vehicle, including a body and the aforementioned headlight structure.

[0027] The vehicle provided in this application, by adopting the aforementioned headlight structure, achieves lower manufacturing costs and enhances the user experience. Attached Figure Description

[0037] 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.

[0038] 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.

[0039] In the field of automotive lighting, crystal-clear materials, with their unique optical refraction properties, have become an important design element. The dynamic and dazzling light effects not only enhance the user's interaction with the vehicle but also improve the overall appearance of the car.

[0040] In related technologies, crystal headlights often employ a backlit lighting architecture. An LED array is placed on the back of a translucent crystal component as the primary light source. Precisely arranged point light sources, combined with a light guide structure, refract light through a prism surface to create a diffused light effect. In the non-operating state, the crystal design relies solely on natural light reflection to present a static visual effect. When the light source is activated, a dense arrangement of LED particles, along with multiple layers of light guide media, is required to achieve dynamic light effects such as gradients and breathing patterns. However, in the aforementioned headlights, the static crystal effect cannot meet users' requirements for dynamic aesthetics in the non-operating state, thus reducing the overall user experience. Moreover, achieving dynamic light effects relies on a high-density LED layout, which not only increases material costs but also causes light energy loss due to the multi-layered light guide structure.

[0041] Based on this, the present application provides a vehicle lamp structure and a vehicle, which reduces the manufacturing cost of the vehicle lamp structure and can reduce light energy loss to a certain extent, thereby reducing the manufacturing cost of the vehicle and improving the user experience of the vehicle.

[0042] The embodiments of this application will be described in detail below with reference to the accompanying drawings and specific implementation details.

[0043] Please combine Figure 1 and Figure 2 , Figure 1 This is a schematic diagram of a first partial structure of the first type of vehicle lamp structure provided in the embodiments of this application. Figure 2 This is a schematic diagram showing the connection relationship between the reflector unit and the rotating shaft in the vehicle headlight structure provided in this embodiment of the application.

[0044] As shown in the figure, this embodiment provides a vehicle lamp structure, including a housing assembly 1, a crystal module 2, and a light source module 3. The housing assembly 1 has a mounting cavity 11 inside and is used to connect to the vehicle body. The crystal module 2 is located in the mounting cavity 11 and connected to the housing assembly 1. The crystal module 2 includes a crystal component 21 and a reflector unit 22. The crystal component 21 has a prism surface 211 and a back surface 212 arranged opposite to each other. The prism surface 211 faces the outside of the vehicle lamp structure, and the reflector unit 22 is arranged facing the back surface 212. The reflector unit 22 includes a plurality of spaced reflectors 221. The light source module 3 is located in the mounting cavity 11 and connected to the housing assembly 1. The light source module 3 is located above the crystal component 21 and can emit light that shines toward the prism surface 211. A plane passing through a horizontal line is defined as the mounting surface. Each reflector 221 has an angle with the mounting surface, and the angle formed between each reflector 221 and the mounting surface is not equal. Each reflector 221 can move relative to the crystal component 21.

[0045] Thus, in the non-illuminated state, the differentiated tilt angle reflector 221 dynamically adjusts to form a multi-level optical path interaction with the prism surface 211. Utilizing the disordered reflection-refraction effect of ambient light, the crystal design can present a natural and smooth flowing light effect without relying on the light source module 3, enhancing the visual appeal of the vehicle when it is static. When the light source is activated, the light projected from the high position is dynamically deflected by the gradient angle reflector 221. Combined with the three-dimensional superimposed light field construction technology, a single light source achieves full coverage of the prism surface 211. This not only simplifies the number of densely arranged LED light sources in related technologies, reducing costs, but also reduces energy loss through optical path optimization.

[0046] In order to facilitate the assembly of the vehicle headlight structure provided in this embodiment, in some optional embodiments, the housing assembly 1 includes a first housing 12 and a second housing 13 connected together. The first housing 12 and the second housing 13 enclose a mounting cavity 11. The first housing 12 is used to connect to the vehicle body. The crystal module 2 and the light source module 3 are both connected to the first housing 12. The second housing 13 is disposed facing the prism surface 211 and is a light-transmitting component.

[0047] In other words, the first shell 12, as the core carrier, integrates the crystal module 2 and the light source module 3 at the same mechanical fulcrum, which not only ensures the stability of the connection between the optical components and the vehicle body, but also reduces installation errors through centralized assembly; while the second shell 13, as a light-transmitting component, is arranged opposite to the prism surface 211 to form an unobstructed light output interface, so that the refracted light from the prism surface 211 of the crystal component 21 can penetrate the second shell 13 and be directly projected outward, which to a certain extent avoids the light efficiency attenuation caused by multiple light-transmitting media in related technologies.

[0048] That is, the enclosed mounting cavity 11 constructed by the first shell 12 and the second shell 13 can not only provide dust and shock protection for the internal optical unit, but also fully preserve the dynamic and dazzling expression of the crystal shape through the light-transmitting characteristics of the second shell 13.

[0049] In some embodiments, to improve the ease of assembly between the first shell 12 and the second shell 13, a snap-fit ​​connection can be used between the first shell 12 and the second shell 13. Please refer to... Figure 1 In this embodiment, a snap-fit ​​groove 121 can be formed on the first shell 12, and the outer edge structure of the second shell 13 can extend into the snap-fit ​​groove 121 and engage with it. In this way, the assembly efficiency between the first shell 12 and the second shell 13 can be improved, thereby improving the assembly efficiency of the vehicle lamp structure provided in this embodiment.

[0050] It should be noted that, regarding the selection of the second shell 13, in the specific implementation of this embodiment, the second shell 13 can be a lens. The lens structure of the second shell 13, together with the prism surface 211, forms a composite optical system, which can perform secondary shaping of the refracted light generated by the crystal module 2. Its surface curvature compensates for the discrete light spot distribution of the prism surface 211, significantly improving the directivity and uniformity of the final emitted light. Compared to ordinary light-transmitting components, the lens-type second shell 13 enhances the spatial layering of the dynamic dazzling light effect through its light-gathering characteristics. Especially when the light source module 3 projects at a high position, it can effectively converge the deflected light from the reflector unit 22, avoiding light energy diffusion loss to a certain extent.

[0051] If the reflector 221 moves relative to the crystal component 21, that is, the reflector 221 can move in the extending direction of the back surface 212, then setting up the drive mechanism for driving the reflector 221 to move becomes relatively difficult. Therefore, in this embodiment, each reflector 221 can rotate relative to the crystal component 21. Specifically, the crystal module 2 also includes a bracket 23, a rotating shaft 24, and a drive mechanism 25. The bracket 23 is connected to the housing assembly 1; the rotating shaft 24 is rotatably connected to the bracket 23, and multiple reflectors 221 are disposed on the rotating shaft 24, with the axis L of the rotating shaft 24 located on the mounting surface; the drive mechanism 25 is used to drive the rotating shaft 24 to rotate, thereby causing each reflector 221 to rotate relative to the crystal component 21.

[0052] When the drive mechanism 25 drives the rotating shaft 24 to rotate, the tilt angle of each reflector 221 changes continuously, causing the reflection path of the light incident on the prism surface 211 to shift periodically. In this way, the spatiotemporal consistency of the motion trajectory of the reflectors 221 mounted on the same rotating shaft 24 is ensured. Through the coplanar design of the rotating shaft 24 and the mounting surface, the mechanical motion is constrained within a two-dimensional plane, reducing the complexity of dynamic optical path compensation.

[0053] In order to connect and support the crystal component 21, the reflector unit 22 and the rotating shaft 24, in some optional embodiments, the bracket 23 includes a first sub-bracket 231 and a second sub-bracket 232 connected together, and the first sub-bracket 231 and the second sub-bracket 232 enclose a mounting groove 233; the crystal component 21, the reflector unit 22 and the rotating shaft 24 are all disposed in the mounting groove 233; wherein, the mounting groove 233 has a bottom wall facing the reflector unit 22, and an aluminum film 234 is disposed on the bottom wall.

[0054] The aluminum film 234 covering the bottom wall of the groove forms a directional reflective substrate, which can reflect the spilled light from the reflector unit 22 to the prism surface 211 a second time, compensating for the light energy loss caused by the angular displacement of the reflector 221 during the rotation of the rotating shaft 24.

[0055] In other words, the physical boundary of the mounting slot 233 limits the relative positional tolerance between the crystal component 21 and the reflector unit 22, which can ensure that the light path always maintains the preset reflection-refraction geometry during dynamic rotation. At the same time, the high reflectivity of the aluminum film 234 suppresses the disordered diffusion of stray light in the mounting slot 233, which can improve the brightness uniformity of the dynamic light effect.

[0056] To prevent the drive mechanism 25 from being visible to the human eye, in this embodiment, the edge of the second sub-bracket 232 extends toward the housing assembly 1 to cover the drive mechanism 25. The edge of the second sub-bracket 232 forms a continuous covering interface at the junction of the housing assembly 1 and the bracket 23, concealing the drive mechanism 25 within the internal assembly space. This ensures that when viewed from outside the vehicle headlights, the mechanical structure of the drive mechanism 25 is physically hidden by the second sub-bracket 232.

[0057] During the operation of the dynamic light effect, the user can only perceive the dazzling changes of the prism surface 211 of the crystal component 21, while the mechanical movement of the drive mechanism 25 is confined to an invisible area, which enhances the aesthetic performance of the headlight structure provided in this embodiment.

[0058] In some alternative implementations, the rotation angle of the shaft 24 is greater than or equal to 20 degrees and less than or equal to 30 degrees.

[0059] In this way, by limiting the rotation angle of the rotating shaft 24, the geometric refraction characteristics of the prism surface 211 of the crystal component 21 can be matched, ensuring that the reflected light spot of the reflector 221 can completely cover the effective working area of ​​the prism surface 211 during rotation, avoiding the delay of light effect transition due to too small an angle or the overflow of edge light energy due to too large an angle.

[0060] Meanwhile, the limitation of the rotation angle of the shaft 24 ensures that the torque load of the drive mechanism 25 is always within the linear response range, which maintains the instantaneous response speed of the reflector 221 deflection and can also prevent the shaft 24 from structural fatigue due to excessive rotation to a certain extent.

[0061] Please continue to combine Figure 3 and Figure 4 , Figure 3 This is a schematic diagram of the second partial structure of the first type of vehicle lamp structure provided in the embodiments of this application. Figure 4 This is a partial structural diagram of the second type of vehicle lamp structure provided in the embodiments of this application.

[0062] Of course, in order to enable the reflective unit 22 to cover the entire back surface and enhance the brilliance of the crystal component 21, in some embodiments, multiple reflective units 22 are provided, and multiple rotating shafts 24 are rotatably connected to the bracket 23. The multiple rotating shafts 24 are arranged one-to-one with the multiple reflective units 22. The driving mechanism 25 includes a driving component 251, an active component 252 and a linkage unit 253. The driving component 251 is connected to the bracket 23, the active component 252 is connected to the driving component 251, and the linkage unit 253 is connected to the active component 252. The linkage unit 253 is driven by each rotating shaft 24. The driving component 251 is used to drive the active component 252 to move, and under the transmission action of the linkage unit 253, it drives each rotating shaft 24 to rotate. The number of reflective units 22 is M or N, and M is greater than N.

[0063] Therefore, when the driving component 251 drives the active component 252, the linkage unit 253 synchronously distributes power to the M or N rotating shafts 24, so that each reflector unit 22 maintains its independent rotational freedom while forming a group motion rhythm through mechanical constraints. Furthermore, the M reflector units 22 can generate a composite dazzling effect of high-density light spots interwoven, while the N reflector units 22 can achieve a rapid response to basic light effects.

[0064] Thus, by using a single driving element 251 to achieve phase synchronization control of the total reflection mirror 221 array, the timing deviation problem caused by multiple driving sources can be avoided to a certain extent.

[0065] The arrangement of the multiple mirror units 22 can be such that the back surface 212 has a first extending direction, which is perpendicular to the axis of the rotating shaft 24; the multiple mirror units 22 are arranged at intervals along the first extending direction, and in the first extending direction, the rotating shaft 24 located in the middle is defined as the middle rotating shaft 24A, and the rotating shafts 24 located on both sides of the middle rotating shaft 24A are defined as the side rotating shafts 24B.

[0066] When the central rotating shaft 24A and the side rotating shaft 24B rotate synchronously under the drive of the linkage unit 253, the reflector units 22 arranged along the first extension direction form an axially radial light path coverage. Specifically, the reflector 221 corresponding to the central rotating shaft 24A is responsible for projecting the main light spot in the central area, while the side rotating shaft 24B drives the reflector 221 to deflect at a compensating angle, extending the reflected light to both wings of the crystal component 21. In this way, the vector control accuracy of light diffusion can be enhanced by utilizing the perpendicular relationship between the first extension direction and the axis of the rotating shaft 24.

[0067] It should be noted that the first extension direction mentioned above is the same as... Figure 3 and Figure 4 The XX axis direction is consistent.

[0068] like Figure 3As shown, in some embodiments, the number of reflector units 22 is M; the driving member 251 is a drive motor, and the driving member 252 is a driving gear, which is disposed on the output shaft 2511 of the drive motor; the linkage unit 253 includes a first driven gear 2534 and a plurality of second driven gears 2535, the first driven gear 2534 is disposed on the central rotating shaft 24A, and the first driven gear 2534 is meshed with the driving gear; the plurality of second driven gears 2535 are disposed one-to-one with the plurality of rotating shafts 24, and two adjacent second driven gears 2535 are meshed with each other; on the central rotating shaft 24A, the first driven gear 2534 and the second driven gears 2535 are spaced apart.

[0069] When the drive motor drives the active gear to rotate via the output shaft 2511, the first driven gear 2534, acting as the primary transmission node of the central rotating shaft 24A, diverts power to the second driven gear 2535 mounted on the central rotating shaft 24A, and then transmits it step by step to the side rotating shafts 24B via adjacent gear meshing chains. This ensures that the M reflector units 22 form a centrally symmetrical angular velocity distribution during rotation. The gear spacing between the central rotating shaft 24A and the side rotating shafts 24B effectively balances the impact of transmission backlash on optical path synchronization. Thus, under the drive of a single drive motor, the ripple-like light effect expansion of the prism surface 211 global reflector array 221 of the crystal component 21 is achieved, ensuring the spatiotemporal continuity of the dynamic, brilliant light spot.

[0070] like Figure 4 As shown, in some other embodiments, the number of reflector units 22 is N; the driving component 251 is a push rod motor, the active component 252 is a main connecting rod, the main connecting rod is rotatably connected to the push rod 2512 of the push rod motor, and the main connecting rod is drive-connected to the central rotating shaft 24A; the linkage unit 253 includes multiple connecting rod assemblies 2531, and the multiple connecting rod assemblies 2531 are arranged one-to-one with multiple side rotating shafts 24B; the connecting rod assembly 2531 includes a first connecting rod 2532 and a second connecting rod 2533 rotatably connected, the first connecting rod 2532 is drive-connected to the corresponding side rotating shaft 24B, the adjacent second connecting rod 2533 is rotatably connected to the main connecting rod, and two adjacent second connecting rods 2533 are rotatably connected.

[0071] When the push rod motor drives the main connecting rod via the push rod 2512, the central rotating shaft 24A acts as the main transmission fulcrum, causing the first connecting rod 2532 to deflect. The hinged design of the adjacent second connecting rod 2533 converts the linear thrust into the rotational torque of the side rotating shaft 24B, forming a light transmission chain with the central part as the wave source. This causes the N reflector units 22 to produce asymmetrical but synchronous angular changes within the push rod stroke.

[0072] In some specific embodiments, the light source module 3 may include a substrate assembly 31 and an LED lamp 32, wherein the substrate assembly 31 is connected to the first housing 12, the LED lamp 32 is disposed on the substrate assembly 31, and the light emitted by the LED lamp 32 can illuminate the prism surface 211.

[0073] During the assembly of the vehicle headlight structure provided in this embodiment, the crystal module 2 and the light source module 3 can be assembled separately first, and then installed into the first housing 12. In this way, modular installation can be achieved, improving the assembly efficiency of the vehicle headlight structure provided in this embodiment.

[0074] This embodiment also provides a vehicle, including a body and the headlight structure described in the above embodiments. It should be noted that the headlight structure has been described in detail in the above embodiments and will not be repeated here.

[0077] 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.
