Abstract

The application provides a vehicle lamp module and a vehicle, which comprise an outer lamp cover, an inner lamp cover, a light emitting part and a thick-wall optical part. A light collector is arranged on the light inlet surface of the thick-wall optical part. The light collector is provided with a light collecting groove with an opening facing the light emitting part. The bottom of the light collecting groove is provided with a light collecting protrusion protruding into the light collecting groove. The surface of the light collecting protrusion is provided with an optical skin. The optical skin is processed at the inlet of the thick-wall optical part. The light is effectively randomly scattered and homogenized before entering the thick-wall optical part. The light entering the thick-wall optical part is highly diffused and homogenized.

It is difficult to produce obvious light and dark stripes or hot spot spots corresponding to the thickness difference directly, so as to ensure the final light emitting effect.

Description

Technical Field

[0001] This application relates to the field of automotive lighting technology, and more particularly to an automotive lighting module and a vehicle. Background Technology

[0002] With the rapid development of the automotive industry, the models of various manufacturers are becoming more and more innovative, and the appearance of each model is becoming more futuristic and the design is more minimalist. In order to highlight the overall aesthetics of the vehicle, more and more headlights are starting to use inner lamp covers. The light output effect of the inner lamp cover is very uniform. However, due to the design requirements of some models, the thickness of the internal wall is not uniform, which will affect the light output effect of the inner lamp cover and cause obvious light source points to appear.

[0003] In related technologies, this problem is solved by adding a texture to the inner lampshade to disperse the light projected onto the inner lampshade and ensure the light output effect. This method can only be used on thick walls with uniform thickness. If the thickness of the thick wall is inconsistent, that is, the light path is inconsistent, it is still impossible to disperse the light evenly to ensure the light output effect. Utility Model Content

[0004] This application provides a vehicle lighting module and vehicle to improve the problem in related technologies where the light cannot be evenly dispersed to ensure the light output effect when encountering thick walls with inconsistent thickness, i.e., inconsistent optical path.

[0005] Firstly, a vehicle lighting module is provided, including:

[0006] External lampshade;

[0007] An inner lampshade, wherein the inner lampshade is disposed on the inner side of the outer lampshade;

[0008] Light-emitting components; and,

[0009] A thick-walled optical component is disposed between the inner lampshade and the light-emitting component. The thick-walled optical component has a light-incident surface and a light-exit surface. The light-incident surface is provided with a condenser. The condenser forms a focusing groove with an opening facing the light-emitting component. A focusing protrusion is formed at the bottom of the focusing groove and protrudes into the focusing groove. The surface of the focusing protrusion is provided with an optical texture.

[0010] The light-focusing protrusion is used to receive the first light emitted by the light-emitting element and transmit it to the light-emitting surface so that the first light is emitted from the light-emitting surface.

[0011] The vehicle headlight module of this application embodiment has a concentrator set on the light-incident surface of the thick-walled optical component. The concentrator forms a concentrating groove with an opening facing the light-emitting component. A concentrating protrusion is formed at the bottom of the concentrating groove and protrudes into the concentrating groove. The surface of the concentrating protrusion is provided with optical texture. By performing optical texture treatment at the entrance of the thick-walled optical component, the light is effectively randomly scattered and homogenized before entering the thick-walled interior. This makes the light entering the thick-walled optical component highly diffused and uniform. Even if the subsequent light travels through different optical paths, the optical path difference mainly affects the overall brightness by a slight decrease or a slight change in uniformity. It is difficult to produce obvious bright and dark stripes or hot spots that are directly corresponding to the thickness difference, like a strong focused beam that has not been pre-dispersed. This ensures the final light output effect.

[0012] In some embodiments, multiple light-concentrating elements are provided, and the multiple light-concentrating elements are arranged sequentially along the extension direction of the light-incident surface. The light-emitting element includes multiple light-emitting lamps, and the multiple light-emitting lamps are arranged in a one-to-one correspondence with the multiple light-concentrating elements.

[0013] In the above embodiments, each concentrator processes light independently, and the impact of optical path differences (such as uneven thickness) of thick-walled optical components on the overall light output effect is weakened. Even if there are local thickness fluctuations in the thick-walled optical components, each concentrator can still ensure that the light from its corresponding light source is transmitted through an independent optical path and forms a uniform light distribution on the light-emitting surface.

[0014] In some embodiments, the light-emitting element further includes a flexible circuit board, the plurality of light-emitting lamps are disposed on the flexible circuit board and are spaced apart along the extension direction of the flexible circuit board, the flexible circuit board being flexible so that the distance between the light-emitting lamps and the corresponding concentrators is the same.

[0015] In the above embodiments, the position of each light lamp is adjusted by deforming the flexible circuit board, so that the optical path (light transmission path length) of each light lamp is consistent with that of the corresponding concentrator. The consistency of the optical path can ensure that the light is efficiently collected, focused and uniformly emitted by the concentrator.

[0016] In some embodiments, the headlight module further includes multiple reinforcing plates, which are located on opposite sides of the flexible circuit board and are arranged in a one-to-one correspondence with the multiple light-emitting lamps.

[0017] In the above embodiments, the reinforcing plates provide local support for the flexible circuit board using a rigid material, counteracting deformation caused by bending or external forces. Each reinforcing plate is precisely aligned with its corresponding LED, ensuring that the LED does not shift during assembly or use.

[0018] In some embodiments, the plurality of the concentrators are connected to each other in the direction of extension of the incident surface.

[0019] In the above embodiments, multiple condensers are connected to each other in the direction of light incident surface extension, so that the multiple condensers are compactly distributed, which can make full use of the position of the light incident surface of the thick-walled optical component, and facilitate the miniaturization and lightweighting of the entire thick-walled optical component.

[0020] In some embodiments, the thick-walled optical element includes a first side surface and a second side surface facing away from each other, the first side surface and the second side surface being located between the light-incident surface and the light-exit surface;

[0021] The concentrator has a first sidewall and a second sidewall arranged opposite to each other, the first sidewall being flush with the first sidewall and the second sidewall being flush with the second sidewall.

[0022] In the above embodiments, it is ensured that the size of the focusing groove on each condenser is consistent on the thick-walled optical component with unequal spacing between the first and second sides, thereby ensuring the consistency of the optical path of the light passing through each condenser as much as possible, and thus ensuring the light output effect.

[0023] In some embodiments, at least a portion of the focusing groove extends through the first side and the second side.

[0024] In the above embodiments, the notches in the sidewalls can reduce stress concentration during demolding and reduce the possibility of concentrator deformation or damage.

[0025] In some embodiments, the concentrator has a reflective surface arched toward the light-emitting element, the reflective surface being provided with an optical pattern, and the sidewall of the concentrating groove is used to receive a second light emitted by the light-emitting element and transmit it to the reflective surface, and then reflect it to the light-emitting surface, where it is emitted.

[0026] In the above embodiment, the second light received by the side wall of the focusing groove is guided by the side wall and reflected by the arched reflective surface to the light-emitting surface, forming a light path superposition with the first light transmitted by the focusing protrusion, ensuring the light emission effect. The optical pattern on the reflective surface can diffuse the light of the light source at a small angle, ensuring that the light emission intensity of the light-emitting surface is consistent and the overall lighting is uniform.

[0027] In some embodiments, the inner lampshade includes a bottom shell and a side shell connected to the periphery of the bottom shell. The side shell and the bottom shell enclose an installation space. At least a portion of the thick-walled optical element is located within the installation space, and the side of the thick-walled optical element is opposite to the side shell. The light-emitting surface of the thick-walled optical element is opposite to the bottom shell. The light emitted from the light-emitting surface is emitted through the bottom shell. The surface of the side shell is provided with a light-shielding layer.

[0028] In the above embodiments, the mounting space enclosed by the bottom shell and side shells provides a precise positioning framework for the thick-walled optical component. The inner surface of the side shell mates with the side of the thick-walled optical component, ensuring its positional stability. The light-shielding layer on the surface of the side shell absorbs or reflects light from directions other than those designed for it, retaining only the high-purity light emitted along the designed path. This prevents light leakage from the side shells and ensures that light only exits from the designated area of ​​the bottom shell.

[0029] Secondly, a vehicle is provided, including a body and the aforementioned headlight module, wherein the headlight module is mounted on the body. Attached Figure Description

[0042] 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.

[0043] 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.

[0044] With the rapid development of the automotive industry, the models of various manufacturers are becoming more and more innovative, and the appearance of each model is becoming more futuristic and the design is more minimalist. In order to highlight the overall aesthetics of the vehicle, more and more headlights are starting to use inner lamp covers. The light output effect of the inner lamp cover is very uniform. However, due to the design requirements of some models, the thickness of the internal wall is not uniform, which will affect the light output effect of the inner lamp cover and cause obvious light source points to appear.

[0045] In existing technologies, this problem is solved by adding a texture to the inner lampshade to disperse the light projected onto the inner lampshade and ensure the light output effect. This method can only be used on thick walls with uniform thickness. If the thickness of the thick wall is inconsistent, that is, the light path is inconsistent, it is still impossible to disperse the light evenly to ensure the light output effect.

[0046] To resolve the above issues, please refer to [link / reference]. Figures 1 to 3 This application provides a vehicle lamp module 1, which includes an outer lamp cover, an inner lamp cover 10, a light-emitting element 20, and a thick-walled optical element 30.

[0047] Specifically, the outer lamp cover is located at the outermost edge of the entire vehicle lamp module 1. It works with the lamp body to form a sealed space, protecting internal components such as the light-emitting element 20, the thick-walled optical element 30, and the inner lamp cover 10 from dust, moisture, and physical damage. As the outermost transparent / semi-transparent cover, it can have specific patterns (such as stripes or frosted) or color coatings (such as red or amber). It is mainly responsible for softening, color filtering, or diffusion of the light transmitted from the interior in accordance with regulations (such as light distribution requirements) and styling needs.

[0048] The inner lamp cover 10 is located inside the outer lamp cover. As the first optical interface that the light comes into contact with after it is emitted from the thick-walled optical component 30, it mainly provides a smooth / uniform transmission surface so that the uniformly transmitted light can be transmitted out with as little disturbance and loss as possible to form the final visual effect. Its shape is responsible for realizing the internal styling design of the headlight (such as crystal feel and three-dimensional feel).

[0049] The light-emitting element 20 is the core of the light source, generating light. It usually refers to an LED chip or LED module, providing the initial illumination required by the vehicle lights.

[0050] A thick-walled optical element 30 is disposed between the inner lamp cover 10 and the light-emitting element 20. The thick-walled optical element 30 has a light-incident surface 31 and a light-emitting surface 32. The light-incident surface 31 is provided with a condenser 33. The condenser 33 forms a condensing groove 33a with an opening facing the light-emitting element 20. A condensing protrusion 33b is formed at the bottom of the condensing groove 33a and protrudes into the condensing groove 33a. The surface of the condensing protrusion 33b is provided with an optical texture 33c. The condensing protrusion 33b is used to receive the first light emitted by the light-emitting element 20 and transmit it to the light-emitting surface 32 so that the first light is emitted from the light-emitting surface 32.

[0051] Optical leather texture 33c features a surface with uniform, random, or leather-like micro-textures (such as frosted or grainy textures). Through scattering, it disperses concentrated light, eliminating localized overexposure or glare and improving lighting uniformity. Please refer to [link to relevant documentation]. Figure 3 In this embodiment, the optical texture 33c is generally grid-like (corn kernel-like).

[0052] The vehicle headlight module 1 of this application embodiment provides a concentrator 33 on the light-incident surface 31 side of the thick-walled optical component 30, and performs optical texture 33c processing at the concentrating protrusion 33b in the concentrator 33, effectively randomizing and homogenizing the light before it enters the thick-walled interior. This makes the light entering the thick-walled optical component 30 highly diffused and uniform. Even if the light subsequently passes through areas of different thicknesses (traversing different optical paths), because the light is uniformly scattered into the concentrator 33, the optical path difference mainly affects a slight decrease in overall brightness or a slight change in uniformity, but does not produce obvious bright and dark stripes or hot spots directly corresponding to the thickness difference, like a strong focused beam that has not been pre-dispersed. This greatly reduces the impact of the internal optical path difference on the final light output effect.

[0053] The light is scattered and homogenized before entering the thick-walled optical component 30, which is equivalent to completing the crucial step of "light homogenization" at the very beginning of the optical path. Although the subsequent optical path difference exists, it is superimposed on the already uniform light distribution, and the negative impact is far less than the effect of a strongly focused beam superimposed on the surface texture after experiencing an optical path difference. Therefore, no matter how complex the shape of the thick-walled component is or how its thickness varies, the final light output effect can achieve a higher degree of uniformity, and it is more difficult to visually perceive the light source point or differences in brightness.

[0054] Further, please refer to Figures 4 to 5 When the light-emitting element 20 extends into the focusing groove 33a, the optical texture 33c on the surface of the focusing protrusion 33b cannot transmit all the light to the thick-walled optical element 30. Some light is diffusely reflected by the optical texture 33c and hits the side wall of the focusing groove 33a. Some divergent light emitted from the edge of the light-emitting element 20 directly hits the side wall of the focusing groove 33a. Therefore, in one embodiment of this application, the focusing device 33 has a reflective surface 33d that arches towards the light-emitting element 20. The reflective surface 33d is provided with an optical pattern 33e. The side wall of the focusing groove 33a is used to receive the second light emitted by the light-emitting element 20 and transmit it to the reflective surface 33d. The light is reflected by the reflective surface 33d to the light-emitting surface 32 and emitted by the light-emitting surface 32. The second light is the light that does not pass through the optical texture 33c and enters the thick-walled optical element 30.

[0055] The second light received by the side wall of the focusing groove 33a is guided by the side wall and reflected by the arched reflective surface 33d to the light-emitting surface 32, forming a superposition of light paths with the first light transmitted by the focusing protrusion 33b, thus ensuring the light output effect.

[0056] Among them, the optical pattern 33e is a microstructure pattern. Each microstructure pattern can be an outwardly convex curved surface, an inwardly concave curved surface, or a plane. In this embodiment, the optical pattern 33e is a grid pattern. Thus, when the second light passes through the reflective surface 33d, it is diffused by the grid pattern and then refracted from the light-emitting surface 32 to the required angle. The light diffusion angle can be controlled by adjusting the size of the grid pattern and the diffusion angle. The area of ​​the diffusion pattern and the diffusion angle are controllable, thereby enabling the light from the light source to diffuse at small angles, ensuring that the light intensity emitted from the light-emitting surface 32 is consistent and the overall lighting is uniform.

[0057] Following the above, multiple condensers 33 are provided, and the multiple condensers 33 are arranged sequentially along the extension direction of the light-incident surface 31. The light-emitting element 20 includes multiple light-emitting lamps 22, and the multiple light-emitting lamps 22 are arranged one-to-one with the multiple condensers 33. Each light-emitting lamp 22 corresponds to one condenser 33, which can more effectively collect and focus light and reduce light energy loss. The sequential arrangement of multiple condensers 33 helps to form a more uniform light distribution on the light-emitting surface 32 and avoid local over-brightness or under-brightness.

[0058] Since each condenser 33 processes light independently, the impact of optical path differences (such as uneven thickness) of the thick-walled optical component 30 on the overall light output effect is weakened. Even if there are local thickness fluctuations in the thick-walled optical component 30, each condenser 33 can still ensure that the light from its corresponding light-emitting lamp 22 is transmitted through an independent optical path and forms a uniform light distribution on the light-emitting surface 32.

[0059] Furthermore, for thick-walled optical components 30 with inconsistent thickness, the uniformity of light output can be ensured by changing the depth of the optical texture 33c. The depth of the optical texture 33c refers to the vertical height (i.e., peak-valley difference) of the micro-uneven structure on the surface of the optical texture 33c. A deeper optical texture 33c means a more significant scattering effect (the light is more strongly dispersed), while a shallower optical texture 33c has a weaker scattering effect (the light maintains a more directional propagation).

[0060] When the optical path is long, a deeper optical texture 33c needs to be set on the focusing protrusion 33b in the corresponding focusing device 33: through a stronger scattering effect, the light is dispersed into a more uniform distribution, which can offset the non-uniformity caused by the long optical path.

[0061] When the optical path is short, a shallow optical texture 33c needs to be set on the focusing protrusion 33b in the corresponding focusing device 33: to maintain a certain scattering effect, while avoiding excessive scattering that would lead to a decrease in light intensity. The microstructure of the shallow texture (such as a low-density frosted texture) only scatters light light slightly, which improves uniformity and retains a high light efficiency (light energy utilization rate).

[0062] In some embodiments, please refer to Figure 4 Multiple concentrators 33 are connected to each other in the extension direction of the light-incident surface 31, forming an integrated continuous optical structure, which reduces the scattering or leakage of light between the independent concentrators 33 and improves the light energy utilization rate.

[0063] Furthermore, by connecting multiple condensers 33 to each other in the direction of extending the light-incident surface 31, the multiple condensers 33 are compactly distributed, which can make full use of the position of the light-incident surface 31 of the thick-walled optical component 30, and facilitate the miniaturization and lightweighting of the entire thick-walled optical component 30.

[0064] Please continue reading Figure 3 and combined Figure 6 In some embodiments, the thick-walled optical element 30 includes a first side surface 34 and a second side surface 35 facing away from each other, the first side surface 34 and the second side surface 35 being located between the light-incident surface 31 and the light-exit surface 32.

[0065] The concentrator 33 has a first sidewall 33f and a second sidewall 33g arranged opposite to each other. The first sidewall 33f is flush with the first sidewall 34, and the second sidewall 33g is flush with the second sidewall 33g.

[0066] Thus, compared to the traditional condenser 33 with a roughly frustum-shaped cross-section, by having the first sidewall 33f of the condenser 33 flush with the first sidewall 34 of the thick-walled optical component 30, and the second sidewall 33g of the condenser 33 flush with the second sidewall 35 of the thick-walled optical component 30, the condenser 33 has sufficient volume to form the focusing groove 33a. This ensures that the size of the focusing groove 33a on each condenser 33 is consistent, even though the distances between the first sidewall 34 and the second sidewall 35 of the thick-walled optical component 30 are not equal. This ensures the consistency of the optical path of the light passing through each condenser 33 as much as possible, thereby ensuring the light output effect.

[0067] Furthermore, since the concentrator 33 is mostly made of plastic injection molding, at least part of the concentrating groove 33a extends through the first side 34 and the second side 35. The notch in the side wall can reduce stress concentration during demolding and prevent the concentrator 33 from deforming or being damaged.

[0068] Since the distance between the first side surface 34 and the second side surface 35 varies along the extending direction of the light-incident surface 31, please refer to the specific embodiments of this application. Figure 2 and combined Figure 6 The distance between the first side 34 and the second side 35 at both ends of the thick-walled optical component 30 is relatively large, while the distance between the first side 34 and the second side 35 in the middle is relatively small. In order to ensure that the size of each condenser 33 is as consistent as possible, thereby ensuring the consistency of the light output effect, the size of the condenser 33 in the middle is the same as that of the condensers 33 at both ends.

[0069] Since the distance between the first side 34 and the second side 35 in the middle is relatively short, in this embodiment of the application, the multiple light-concentrating grooves 33a located in the middle section extend through the first side 34 and the second side 35. In this way, the notch in the side wall can reduce stress concentration during demolding and reduce the possibility of deformation or damage to the light-concentrating device 33.

[0070] Following the above, the light-emitting component 20 also includes a flexible circuit board 21, on which a plurality of light-emitting lamps 22 are disposed, and the plurality of light-emitting lamps 22 are spaced apart along the extension direction of the flexible circuit board 21. The flexible circuit board 21 is flexible so that the distance between the plurality of light-emitting lamps 22 and the corresponding condenser 33 is the same.

[0071] By using the flexible circuit board 21, the position of each light lamp 22 is adjusted so that the optical path (light transmission path length) of each light lamp 22 is consistent with that of the corresponding concentrator 33. The consistency of the optical path can ensure that the light is efficiently collected, focused and uniformly emitted by the concentrator 33.

[0072] The flexibility of the flexible circuit board 21 allows it to adapt to the complex shape of the headlights (such as curved, arc or irregular structure), and the high adaptability enables the headlight module 1 to be integrated into the front face design of the vehicle, improving the consistency of the overall vehicle appearance.

[0073] The spaced arrangement of multiple light-emitting lamps 22 can form a "multi-point light source" effect on the light-emitting surface 32. By adjusting the optical structure of each concentrator 33, such as the thickness of the optical texture 33c, the light intensity distribution in each area can be precisely controlled to ensure the uniformity of light output.

[0074] Furthermore, to ensure that the flexible circuit board 21 has sufficient strength to mount the light lamp 22, please refer to... Figure 1 and Figure 4 The headlight module 1 also includes multiple reinforcing plates 40, which are located on opposite sides of the flexible circuit board 21, and the multiple reinforcing plates 40 and the multiple light lamps 22 are arranged in a one-to-one correspondence.

[0075] The reinforcing plate 40 provides local support for the flexible circuit board 21 using a rigid material (such as aluminum, stainless steel, or high-strength plastic) to counteract the deformation of the flexible circuit board 21 caused by bending or external forces. Each reinforcing plate 40 is precisely aligned with the corresponding light lamp 22 to ensure that the light lamp 22 does not shift during assembly or use.

[0076] If the reinforcing plate 40 is made of metal (such as aluminum), it can also serve as a heat sink, quickly dissipating the heat generated by the light lamp 22 into the air through heat conduction, thus preventing heat from accumulating locally on the flexible circuit board 21.

[0077] In this embodiment, the flexible circuit board 21 is arranged in a stepped pattern, designed as multiple stepped platforms. Each platform is equipped with a set of light-emitting lamps 22 and a reinforcing plate 40. By adjusting the height and horizontal position of the steps, the optical path (light transmission path length) between each light-emitting lamp 22 and the corresponding concentrator 33 can be precisely controlled, ensuring optical path consistency. The stepped distribution disperses the bending stress of the flexible circuit board 21 across multiple stepped platforms, avoiding local stress concentration caused by a single large-angle bend. Each stepped platform provides local support through the reinforcing plate 40, further offsetting the deformation of the flexible circuit board 21.

[0078] To eliminate stray light and improve the light emission of the inner lampshade 10, please refer to... Figure 6In one embodiment of this application, the inner lamp cover 10 includes a bottom shell 11 and a side shell 12 connected to the periphery of the bottom shell 11. The side shell 12 and the bottom shell 11 enclose an installation space 10a. At least a portion of the thick-walled optical element 30 is located within the installation space 10a, and the side of the thick-walled optical element 30 is opposite to the side shell 12. The light-emitting surface 32 of the thick-walled optical element 30 is opposite to the bottom shell 11. The light emitted from the light-emitting surface 32 is emitted through the bottom shell 11. The surface of the side shell 12 is provided with a light-shielding layer.

[0079] It should be understood that the side surface of the thick-walled optical component 30 is the peripheral side surface of the thick-walled optical component 30, and is located between the light-incident surface 31 and the light-exit surface 32, and connects the light-incident surface 31 and the light-exit surface 32. The side surface of the thick-walled optical component 30 includes the first side surface 34 and the second side surface 35 mentioned above.

[0080] The mounting space 10a enclosed by the bottom shell 11 and the side shell 12 provides a precise positioning frame for the thick-walled optical component 30. By mating the inner surface of the side shell 12 with the side of the thick-walled optical component 30, its positional stability is ensured, assembly errors are reduced, and displacement of the thick-walled optical component 30 due to vibration or thermal expansion is avoided. The mounting space 10a integrates the thick-walled optical component 30 and the inner lamp cover 10 into a module, which facilitates the overall assembly into the vehicle lamp module 1, reduces subsequent adjustment steps, and improves production efficiency.

[0081] The light-emitting surface 32 of the thick-walled optical element 30 faces the base shell 11, which can be designed as a structure with specific optical functions (such as a scattering surface, Fresnel lens, or microprism array). After light is emitted from the thick-walled optical element 30, it is further modulated by the base shell 11 to achieve uniform illumination or a specific light pattern. Meanwhile, a light-shielding layer (such as a black light-absorbing coating) on ​​the surface of the side shell 12 can absorb or reflect light from directions other than the design direction, retaining only high-purity light emitted from the designed path. This prevents light leakage from the side shell 12 and ensures that light only exits from the area specified by the base shell 11.

[0082] The bottom shell 11 can be injection molded integrally with the side shell 12, which distributes stress evenly, improves the overall resistance to deformation, and at the same time reduces subsequent assembly steps and alignment adjustments, reduces manufacturing difficulty, and improves product consistency.

[0083] In one embodiment of this application, a vehicle is also provided. The vehicle includes a body and a headlight module 1. The headlight module 1 is installed on the body. The headlight module 1 refers to the above embodiments. Since the vehicle adopts all the technical solutions of all the above embodiments, it has at least all the beneficial effects brought about by the technical solutions of the above embodiments, which will not be described in detail here.

[0084] It should also be understood that the vehicle can be a new energy vehicle, or a fuel vehicle or other vehicle that requires the headlight module 1, without any restrictions.

[0085] The above-disclosed embodiments are merely preferred embodiments of this application and should not be construed as limiting the scope of this application. Therefore, any equivalent variations made in accordance with the claims of this application shall still fall within the scope of this application.
