Description

Technical Field

[0001] This application relates to the field of vehicle lighting technology, and in particular to an integrated high and low beam optical module and vehicle. Background Technology

[0002] In conventional single high beam and single low beam modules, because the high beam module and low beam module are designed separately from each other, only the low beam module is lit when the low beam module is lit, and the high beam part looks very empty; or the low beam part also has the problem of visual emptiness when the high beam module is lit, making the overall headlight shape lack harmony. Utility Model Content

[0003] This application aims to solve at least one of the technical problems existing in the prior art, and to provide an integrated high and low beam optical module and vehicle.

[0005] The low beam section includes a low beam main module and a low beam broadening module arranged adjacent to each other along a first direction. The low beam main module and the low beam broadening module are configured to emit light and project it to form a low beam main beam pattern and a low beam broadening beam pattern, respectively.

The generatrix of the light-exit surface of the main outer lens unit extends in the same direction as the vehicle width, and the generatrix of the light-incident surface of the main inner lens unit extends perpendicular to the generatrix of the light-exit surface of the main outer lens unit.

[0025] In one embodiment, the primary low-beam reflector and / or the low-beam broadening reflector includes:

[0026] reflective ontology;

[0027] A cover fitting part is connected to the front end of the reflective body along the light emission direction, and the cover fitting part covers the near beam main lens portion and / or near beam broadening lens portion from above.

[0034] This embodiment integrates high and low beam functions. The low beam main module and the low beam widening module are arranged adjacent to each other, with the high beam portion located on both sides of the low beam portion. In low beam mode, the low beam is lit independently, and the central luminous area is continuous. In high beam mode, because the brightness and luminous power of the high beams on both sides are very strong, the central low beam portion does not appear noticeably darker when the high beam portion is lit. Alternatively, in high beam mode, both high and low beams can be lit simultaneously, with a continuous luminous area. That is, regardless of whether it is high beam mode or low beam mode, the appearance is basically the same, avoiding obvious dark spots or hollowness. Attached Figure Description

[0059] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.

[0060] In the description of this application, it should be noted that, unless otherwise expressly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection, an electrical connection, or a connection that allows communication between them; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication between two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this application according to the specific circumstances.

[0061] The integrated high and low beam optical module, vehicle lights, and vehicles of this application will be described in detail below with reference to the accompanying drawings and specific embodiments.

[0062] A high-beam and low-beam integrated optical module, having a light emission direction Y, includes:

[0063] The low beam section includes a low beam main module 21 and a low beam broadening module 11 arranged adjacently along the first direction X. The low beam main module 21 and the low beam broadening module 11 are configured to emit light to the light-emitting surface and project it to form a low beam main beam pattern and a low beam broadening beam pattern, respectively.

[0064] The high beam portion is arranged side by side with the low beam portion in the first direction X, and the high beam portion is located on both sides of the low beam portion along the first direction X, which intersects with the light emission direction Y.

[0065] Specifically, in low beam mode, the low beam main module 21 and the low beam widening module 11 need to be lit simultaneously. The low beam main module 21 concentrates and projects light to form the low beam main beam pattern; the low beam widening module illuminates a larger range of light to expand the width of the low beam. The low beam main beam pattern and the low beam widening beam pattern together form the low beam.

[0066] The high beam section is located on both sides of the low beam section along the first direction X. If the high beam section were located in the middle of the low beam section, in low beam mode, the middle high beam section would appear dim because it is not illuminated, and the center of the headlight would still show obvious dark spots or a hollow feeling (because high beams require high brightness, the high beam section is usually designed to be larger). In this embodiment, high and low beam functions are integrated, and the high beam section is located on both sides of the low beam section (i.e., the low beam is in the middle, and the high beam is on both sides). In low beam mode, the low beam is illuminated alone, and the luminous area in the middle is continuous. In high beam mode, because the brightness and luminous power of the high beams on both sides are very strong, the middle low beam section will not appear noticeably darker when the high beam section is illuminated. Alternatively, in high beam mode, both high and low beams can be illuminated simultaneously, and the luminous area is continuous. That is, whether in high beam mode or low beam mode, the appearance effect is basically the same, which can avoid obvious dark spots or a hollow feeling.

[0067] Secondly, if the low beam section is located on the periphery of the high beam section, the low beam section has a poor ability to focus light towards the middle of the low beam pattern, resulting in a decrease in the clarity of the low beam cutoff line and making it difficult to meet regulatory requirements.

[0068] Traditional high-beam solutions sometimes use mirrors to reflect light emitted from the light source so that it is projected parallel to the surrounding light. However, this optical design offers limited freedom and makes it difficult to achieve a highly uniform light distribution. Improving high-beam uniformity requires increasing the width of the high-beam module, but current car headlights, with their increasing functionality, directly encroach on the space available for the high-beam module, leaving increasingly less space for its placement. Therefore, [reference needed] Figures 1-3 An embodiment in which the high beam portion includes:

[0069] The high beam main module 41 and the high beam widening module 31 are arranged side by side along the first direction X (usually the left and right direction of the vehicle width) and are configured to emit light to the light-emitting surface and project to form the high beam main beam pattern and the high beam widening beam pattern, respectively; the first direction X intersects the light-emitting direction Y.

[0070] The main high beam pattern and the extended high beam pattern together form the high beam;

[0071] The high beam main module 41 includes a high beam main reflector 411 and a high beam main lens 412 arranged sequentially along the light output direction Y. The high beam widening module 31 includes a high beam widening reflector 311 and a high beam widening lens 312 arranged sequentially along the light output direction Y.

[0072] The high beam primary reflector 411 is an ellipsoidal reflector with a first focal point and a second focal point arranged sequentially along the light output direction Y.

[0073] Specifically, in high beam mode, the high beam main module 41 and the high beam widening module 31 need to be lit simultaneously. The high beam main module 41 illuminates the light in a concentrated manner to form the high beam main beam pattern; the high beam widening module 31 illuminates a larger range of light to extend the width of the high beam. The high beam main beam pattern and the high beam widening beam pattern together form the high beam.

[0074] In this embodiment, the high beam main reflector 411 has a first focal point and a second focal point arranged sequentially along the light output direction Y. The light emitted by the light source at the first focal point is reflected by the high beam main reflector 411 and then emitted forward at the second focal point, thereby strongly converging the light and forming a small diameter high beam, thereby improving the brightness of the central area of ​​the high beam.

[0075] In this embodiment, the overall brightness of the enhanced high beam pattern central area can be flexibly adjusted by adjusting the spatial position of the second focal point of the high beam main reflector 411; and, since the light reflected by the high beam main reflector 411 converges to the second focal point in front of the light output direction Y, the high beam main beam is narrowed and has a very small diameter, allowing it to be close to the side of the high beam main module 41 (e.g., Figure 3 A high-beam widening module 31 is installed at the location of the second focal point to expand the beam width, thereby helping to reduce the overall size of the optical module along the first direction X. Therefore, the high-beam solution designed in this application can achieve better high-beam lighting effect even with very limited module space.

[0076] In this embodiment, the light reflected by the high beam main reflector 411 will enter the high beam main lens 412, and the light reflected by the high beam widening reflector 311 will enter the high beam widening lens 312. That is, the high beam main module 41 and the high beam widening module 31 in this embodiment adopt a reflector design scheme, which can reflect the light emitted by the light source to a preset direction.

[0077] refer to Figure 3 In some embodiments, the high beam broadening reflector 311 is positioned in front of the high beam main reflector 411 along the light emission direction Y.

[0078] Specifically, since the light reflected by the high beam main reflector 411 converges to the second focal point in front of the light output direction Y, the main beam of the high beam is narrowed and has a very small diameter. The high beam widening reflector 311 can be placed forward in the narrowed area of ​​the light reflected by the high beam main reflector 411, which is beneficial to reduce the overall size of the optical module along the light output direction Y.

[0079] Furthermore, since the high beam widening reflector 311 is located in front of the high beam main reflector 411, when the high beam main lens 412 and the high beam widening lens 312 are connected and share the same light-emitting surface, the distance between the high beam widening reflector 311 and the high beam widening lens 312 along the light-emitting direction Y is smaller than the distance between the high beam main reflector 411 and the high beam main lens 412. This is beneficial to reduce the size of the entire high beam widening module 31 in the front-back direction.

[0080] refer to Figure 3 In some embodiments, the second focal point is located between the high beam primary reflector 411 and the high beam primary lens 412.

[0081] Specifically, the light reflected by the high-beam main reflector 411 converges at position n, where the second focal point is located. Therefore, the lateral space occupied near the second focal point is minimized (the width of position n in the diagram). Consequently, a high-beam widening reflector 311 can be arranged on the side of position n, which helps to reduce the overall size of the optical module along the light-emitting direction Y. At this time, the front-to-back position of the high-beam widening reflector is consistent with or substantially consistent with the front-to-back position of the second focal point (the front-to-back position is close and does not exceed 5mm).

[0082] refer to Figure 3 and Figure 4 In some embodiments, there are two or more high beam widening reflectors 311 arranged side by side; at least one of the high beam widening reflectors 311 emits light toward one side of the other high beam widening reflector 311.

[0083] The high beam widening lens 312 and the high beam main lens 412 share the same light-emitting surface.

[0084] Specifically, the high-beam widening reflector 311 emits light towards one side of another high-beam widening reflector 311, allowing each high-beam widening reflector 311 to emit light in a cross-shaped manner. This cross-emitting light pattern increases the width of the high-beam pattern compared to the parallel forward emission of light. Simultaneously, because the overall size of the optical module is small, the space available for arranging the high-beam widening reflectors 311 is also small. Therefore, the left and right openings of the high-beam widening reflectors 311 are very small. In this case, if the high-beam widening reflectors 311 emit light directly forward, the expansion of the light pattern width is very limited. Therefore, emitting light towards one side of another high-beam widening reflector 311 in a cross-shaped manner helps to expand the light pattern width. (Comparison) Figure 4As can be seen on the left side, if space permits, two additional widening direct beam modules 51 can be installed to the left of the main high beam reflector 411. Each widening direct beam module 51 includes a widening direct beam reflector 511 and a widening direct beam lens 512. This increases the opening size of the two widening direct beam reflectors 511 on the left, and these two widening direct beam reflectors 511 are positioned in the same or substantially the same direction as the main high beam reflector 411 in the front-to-back direction (for example, they can be 0-10mm apart). In this case, the high beam widening reflector 311 can emit light directly forward, thus widening the high beam pattern and increasing the distance and brightness of the high beam pattern illuminating directly forward.

[0085] Furthermore, since the high beam broadening reflector 311 is located in front of the high beam main reflector 411 and the distance between the high beam broadening reflector 311 and the high beam broadening lens 312 is very small, if the high beam broadening reflector 311 emits light directly forward, the optical path will be insufficient and the expected light pattern cannot be formed. However, by directing the high beam broadening reflector 311 to emit light towards the side of another high beam broadening reflector 311, the optical path of the high beam broadening beam can be increased, which is beneficial to forming a complete high beam broadening light pattern.

[0086] In addition, the number of high beam widening reflectors 311 is greater than the number of high beam main reflectors 411, which is also beneficial to fully expand the width of the high beam along the first direction X.

[0087] In this embodiment, the high beam broadening reflector 311 emits light towards one side of another high beam broadening reflector 311, thereby achieving cross-coordinated light emission. Therefore, the high beam broadening lens 312 and the high beam main lens 412 share the same light-emitting surface, preventing the cross light rays from leaking out between the high beam broadening lens 312 and the high beam main lens 412 and affecting the light pattern presentation.

[0088] In this embodiment, the number of high beam widening reflectors 311 set on one side of the high beam main reflector 411 is two, and they are arranged adjacent to each other. This is beneficial for integrating components with the same function, avoiding separate settings that increase structural and optical complexity, and reducing the number of molds required.

[0089] refer to Figure 3 and Figure 4 In some embodiments, the high-beam widening reflector 311 is a parabolic reflector. A parabolic reflector can direct the beam of light in parallel, which is beneficial for widening the beam pattern.

[0090] refer to Figure 3In some embodiments, a main beam receiving portion 413 is also included, with its two ends connected to the front ends of the high beam main lens 412 and the high beam main reflector 411 along the light output direction Y, respectively; from the high beam main reflector 411 to the second focal point, the width of the main beam receiving portion 413 along the first direction X gradually decreases to form a cavity for receiving the high beam main beam.

[0091] Specifically, based on the above embodiments, along the light-emitting direction Y, multiple high-beam broadening reflectors 311 can be arranged at the second focal point of the high-beam broadening reflector 311, that is, at the narrowest position where n is located. This will directly encroach on and compress the space of the high-beam main beam, and may cause interference to the high-beam main beam, affecting the presentation of its light pattern. Therefore, this embodiment sets up a main beam receiving part 413, which can provide an independent receiving space for the high-beam main beam, ensure the normal presentation of the high-beam main beam pattern, and avoid interference from surrounding components to the high-beam main beam. At the same time, along the light-emitting direction Y, the width of the main beam receiving part 413 gradually decreases along the first direction X, so that the width of the cavity formed also gradually decreases along the first direction X, which can be adapted to the high-beam main beam that gradually narrows along the light-emitting direction Y, and can just accommodate the high-beam main beam. Moreover, the conical main beam receiving part 413 can save more space.

[0092] Furthermore, a reflective layer is provided on the inner wall of the main beam receiving portion 413. After the main beam of the high beam hits the reflective layer on the inner wall of the main beam receiving portion 413, it can be reflected forward again, thereby ensuring that the main beam of the high beam can have high brightness.

[0093] The main beam receiving part 413 can also limit the high beam main lens 412 from above, restricting the displacement of the lens in the vertical direction, reducing the lens from violently vibrating up and down with the vehicle during vehicle use, which helps to ensure the stability of the position and shape of the emitted beam pattern.

[0094] refer to Figures 6-9 The low beam main module 21 and the low beam broadening module 11 share a light-emitting surface and are configured to emit light to the light-emitting surface and project it to form a low beam main beam and a low beam broadening beam, which together form the low beam.

[0095] The low beam main module 21 includes a low beam main reflector 211 and a low beam main lens portion 212 arranged sequentially along its light output direction; the low beam broadening module 11 includes a low beam broadening reflector 111 and a low beam broadening lens portion 112 arranged sequentially along its light output direction.

[0096] The light-incident surface 212d of the near beam main lens portion 212 is used to adjust the extended light in the first direction X, and the light-exiting surface of the near beam main lens portion 212 is used to adjust the extended light in the second direction Z, which is perpendicular to the first direction X; along the light-exiting direction, the thickness of the near beam main lens portion 212 is greater than the thickness of the near beam broadening lens portion 112.

[0097] Specifically, in low beam mode, the low beam main module 21 and the low beam widening module 11 need to be lit simultaneously. The low beam main module 21 illuminates the light in a concentrated manner to form the low beam main beam pattern; the low beam widening module illuminates a larger range of light to expand the width of the low beam. The low beam main beam pattern and the low beam widening beam pattern together form the low beam.

[0098] The light reflected by the low beam main reflector 211 will enter the low beam main lens section 212, and the light reflected by the low beam broadening reflector 111 will enter the low beam broadening lens section 112. That is, the low beam main module 21 and the low beam broadening module 11 in this embodiment adopt a reflector design scheme, which can converge the light emitted by the light source to a preset direction.

[0099] In this application, the light-incident surface 212d of the low beam main lens portion 212 can expand the illumination width and increase the illumination range of the light source in the first direction (vehicle width direction). Correspondingly, the brightness of the main beam pattern is reduced, and the difference between the brightness of the main beam pattern and the side-widened beam pattern can be reduced, so the brightness connection between the main beam pattern and the widened beam pattern is more natural, and the brightness of the low beam pattern is uniform throughout. The uniform brightness of the low beam will not cause visual fatigue of the human eye.

[0100] The light-incident surface 212d of the low-beam main lens portion 212 represents diffusion in the first direction X (left-right direction of vehicle width), while the light-exit surface is designed for diffusion in the second direction Z (up-down direction). The light-incident surface 212d is closer to the light source than the light-exit surface, therefore the focal length of the light-incident surface 212d is shorter than that of the light-exit surface. Since focal length is inversely proportional to magnification, the image in the left-right direction is larger than the image in the up-down direction on the same screen. In this application, by adjusting the curvature of the light-incident surface 212d and the light-exit surface of the low-beam main lens portion 212, the focal length ratio between them can be changed, thereby altering the width-to-height ratio of the main beam pattern. Ultimately, this results in better edge-fitting of the main beam pattern, i.e., a better visual effect of the low-beam boundary on the road surface.

[0101] Regarding edge alignment, this specifically refers to the following: the straighter the light pattern on the left and right shoulders, and the wider the dimensions of the left and right shoulders, the better the illumination effect on the corresponding road edge, ensuring that the entire field of vision is illuminated without any obvious dark areas. For example... Figure 11 This is a diagram of a traditional low beam. Figure 10This is a schematic diagram of the low beam formed by superimposing the main beam pattern and the side-widened beam pattern of this application. It can be seen that the beam pattern at the left and right shoulders of the main beam pattern of this application is straight and the width of the left and right shoulders is larger. Therefore, the shape of the main beam pattern and the side-widened beam pattern are connected more naturally and straightly, and the edge fit is better.

[0102] It is worth noting that the thickness of the aforementioned primary low beam lens portion 212 refers to the size of the primary low beam lens portion 212 as a whole (which can be a single lens or a lens group) in the front-to-back direction. In other words, when the primary low beam lens portion 212 comprises multiple lens units spaced apart front to back, the primary low beam lens portion 212 is in the form of a lens group, and the thickness of the primary low beam lens portion 212 in this case is the thickness of the lens group in the front-to-back direction (including the thickness of the lens unit itself and the spacing between adjacent lens units).

[0103] In this application, the thickness of the low beam main lens portion 212 is designed to be larger, which results in a larger distance between the light-incident surface and the light-outcident surface of the low beam main lens portion 212, a larger width and a larger aspect ratio of the main beam pattern, and ultimately better edge fit of the main beam pattern, that is, a better visual effect of the low beam boundary on the road surface.

[0104] For example, the low beam section may include multiple low beam reflectors arranged along the vehicle width direction, such as... Figure 6 The low beam reflector shown can be set to six, all located in the middle, to work together to form the low beam.

[0105] refer to Figure 6 and Figure 8 In some embodiments, the low beam main lens portion 212 is connected to the low beam broadening lens portion 112 and forms a common light-emitting surface on the light-emitting side; in this case, along the light-emitting direction, the light-incident surface of the low beam main lens portion 212 is located behind the light-incident surface of the low beam broadening lens portion 112.

[0106] Specifically, in this application, the low beam main lens portion 212 and the low beam widening lens portion 112 are connected and share a light-emitting surface, which can realize integrated design and save design costs; when the low beam main reflector 211 and the low beam widening reflector 111 are lit, light will be emitted from the shared light-emitting surface.

[0107] Furthermore, when the low beam main lens portion 212 and the low beam broadening lens portion 112 share a light-emitting surface, since the overall thickness of the low beam main lens portion 212 is larger than that of the low beam broadening lens portion 112, the spatial position of the light-incident surface of the low beam main lens portion 212 will be further back (compared to the light-incident surface of the low beam broadening lens portion 112), which is beneficial to improving the width and aspect ratio of the main beam pattern.

[0108] refer to Figure 8 In some embodiments, the primary low beam reflector 211 and the low beam widening reflector 111 are arranged along a first direction. There are two primary low beam reflectors 211 arranged adjacent to each other. The number of low beam widening reflectors 111 is greater than the number of primary low beam reflectors 211, and each low beam widening reflector 111 emits light toward one side of the other low beam widening reflector 111.

[0109] In this application, there are two primary reflectors 211 for low beam, which are arranged adjacent to each other. This is beneficial for integrating components with the same function into a single design, avoiding the increase in structural and optical complexity due to separate installations, and reducing the number of molds required.

[0110] In this embodiment, the near beam widening reflector 111 emits light towards one side of the other near beam widening reflector 111, so that each near beam widening reflector 111 can emit light in a cross pattern. Compared with the form of emitting light in parallel forward, the cross pattern can increase the width of the near beam pattern. The number of near beam widening reflectors 111 is greater than the number of near beam main reflectors 211, which is also beneficial to fully expand the width of the near beam along the first direction.

[0111] refer to Figure 17 In some embodiments, the root of the near-light main reflector 211, away from the near-light main lens portion 212, is provided with a bent feature line k.

[0112] Specifically, when the primary reflector 211 reflects light forward, the bending feature line k at its root is projected out and will correspondingly form the cutoff line feature of the upper boundary of the near beam.

[0113] refer to Figure 12 In some embodiments, the near-light main lens portion 212 includes a main inner lens unit 212a and a main outer lens unit 212b, wherein the light-emitting surface of the main inner lens unit 212a is adjacent to and spaced apart from the main outer lens unit 212b.

[0114] The light-incident surface 212d of the main inner lens unit 212a and the light-exit surface of the main outer lens unit 212b are both cylindrical. The generatrix of the light-exit surface of the main outer lens unit 212b extends in the same direction as the vehicle width, and the generatrix of the light-incident surface 212d of the main inner lens unit 212a extends perpendicular to the generatrix of the light-exit surface of the main outer lens unit 212b.

[0115] Specifically, the generatrix of the light-emitting surface of the main outer lens unit 212b extends in the same direction as the vehicle width, allowing for vertical adjustment and expansion of the light pattern. The generatrix of the light-incident surface 212d of the main inner lens unit 212a extends perpendicular to the vehicle width, allowing for adjustment and expansion of the light in the left and right vehicle width directions. Furthermore, the light-incident surface 212d of the main inner lens unit 212a is close to the reflector and has a short focal length, which is beneficial for fully expanding the light pattern in the left and right directions.

[0116] Secondly, for convex lenses, the shorter the focal length, the wider the beam pattern, and the thicker the lens. Therefore, to achieve greater beam widening, the thickness of the lens along the light-emitting direction needs to be increased. However, increased thickness inevitably leads to increased lens weight, longer injection molding cycles, and correspondingly higher production costs. Figure 12 In the embodiments, the near-light main lens portion 212 is preferably configured as two lenses, a main inner lens unit 212a and a main outer lens unit 212b. Compared with a single lens, the middle part is eliminated, the weight is reduced, the thin lens saves materials and reduces production costs.

[0117] For example, in this embodiment, the main external lens unit 212b can be designed to adjust the extended light along the first direction on one side of the light-emitting surface, or it can be designed to adjust the extended light along the first direction on both sides of the light-emitting surface and the light-incident surface.

[0118] refer to Figure 12 In some embodiments, the primary low-beam reflector 211 and / or the low-beam broadening reflector 111 include:

[0119] Reflector body 211a;

[0120] The cover fitting part 211b is connected to the front end of the reflective body 211a along the light emission direction, and the cover fitting part 211b covers the near beam main lens part 212 and / or the near beam broadening lens part 112 from above.

[0121] Specifically, in this embodiment, the covering and fitting part 211b covers the low beam main lens part 212 and / or the low beam widening lens part 112 from above. On the one hand, it can prevent light from leaking out from the surface of the low beam main lens part 212 and / or the low beam widening lens part 112; on the other hand, it limits the low beam main lens part 212 and / or the low beam widening lens part 112 from above, restricting the displacement of the lens in the vertical direction, reducing the violent vertical vibration of the lens with the vehicle during vehicle use, and helping to ensure the stability of the position and shape of the emitted light pattern.

[0122] refer to Figure 12In some embodiments, the inner surface of the cover mating portion 211b near the near beam main lens portion 212 and / or the near beam broadening lens portion 112 is provided with a groove 211c, the groove 211c matching the surface contour shape of its adjacent lens to accommodate at least a portion of the lens.

[0123] For example, taking the cooperation between the main inner lens unit 212a and the cover fitting part 211b as an example: the groove 211c of the main inner lens unit 212a and the cover fitting part 211b are shaped to match, thereby achieving fitting assembly. On the one hand, compared to a simple vertical arrangement, when the two are fitted together in the vertical direction, it is beneficial to reduce the size of the mating assembly formed by the main inner lens unit 212a and the cover mating part 211b in the vertical direction. This is beneficial to reduce the size of the entire optical module in the vertical direction. When installed inside the lamp, it occupies less space inside the lamp and the arrangement is more flexible. Especially in the context of current intelligent vehicle lights, the lamp integrates more functions, and a smaller optical module can reduce the layout difficulty of the internal structure of the entire lamp. On the other hand, when the groove 211c of the main inner lens unit 212a and the cover mating part 211b are matched and fitted together, the groove 211c can directly restrict the spatial position of the main inner lens unit 212a, making the spatial position of the lens stable. The stable relative position between the two is also beneficial to ensure the light emission accuracy. Overall, it is beneficial to improve the stability of the position and shape of the emitted light pattern.

[0124] Furthermore, the wall thickness of different parts of the covering mating part 211b is consistent, or the difference in wall thickness of different parts of the covering mating part 211b does not exceed 1mm. In this embodiment, under the premise that the shape of the groove 211c of the main inner lens unit 212a and the covering mating part 211b matches, by adopting this setting, the size of the mating assembly formed by the main inner lens unit 212a and the covering mating part 211b in the vertical direction can be further reduced. This will reduce the size of the entire optical module in the vertical direction, and when installed inside the lamp, it will occupy less space inside the lamp and be more flexible in arrangement. Especially in the context of current intelligent vehicle lights, more functions are integrated inside the lamp, and a smaller optical module can significantly reduce the layout difficulty of the internal structure of the entire lamp.

[0125] refer to Figure 17 In some embodiments, the cover fitting part 211b is provided with a square positioning through groove 211d that extends through its inner and outer surfaces. The low beam main lens part 212 and / or the low beam widening lens part 112 are provided with a positioning plate 212c on the side near the cover fitting part 211b. The positioning plate 212c matches the shape of the square positioning through groove 211d and is inserted into it.

[0126] Specifically, taking the main inner lens unit 212a as an example, after the positioning plate 212c and the square positioning slot 211d are matched and inserted, the relative position between the main inner lens unit 212a and the cover fitting part 211b in the horizontal direction can be directly restricted. The relative position between the two is stable, which is conducive to ensuring the light emission accuracy and overall helps to improve the stability of the position and shape of the emitted light pattern.

[0127] Secondly, the positioning plate 212c and the square positioning slot 211d are shaped and interlocked, which can prevent the main inner lens unit 212a from rotating relative to the cover fitting part 211b in the horizontal plane; and the cover fitting part 211b can effectively limit the displacement of the main inner lens unit 212a in the vertical direction by blocking.

[0128] The mating design in this embodiment eliminates the need for fasteners such as bolts, thus avoiding structural weakening caused by drilling screw holes. It also achieves stability comparable to traditional fastening methods through multi-dimensional constraints, while retaining the advantages of lightweight and efficient assembly.

[0129] refer to Figure 16 In some embodiments, a carrier 213 is also included, disposed on the side of the near beam main lens portion 212 and / or the near beam widening lens portion 112 away from the cover mating portion 211b, and the bearing surface of the carrier 213 is provided with a groove 213a that conforms to the end face contour of the near beam main lens portion 212 and / or the near beam widening lens portion 112, for fitting and accommodating the end face of the near beam widening lens portion 112.

[0130] For example, the carrier 213 can be a heat sink, capable of supporting a light source plate 214 (used to project light onto the near beam primary reflector 211) that is optically matched with the near beam primary reflector 211. The end face of the main inner lens unit 212a on the side away from the cover fitting part 211b is fitted into the groove 213a. The groove 213a can restrict the spatial position of the main inner lens unit 212a in the horizontal plane, which is beneficial to fix the lower position of the main inner lens unit 212a and ensure the light emission accuracy. Furthermore, the groove 213a and the groove 211c of the upper cover fitting part 211b work together to form a bidirectional positioning in the vertical direction, which can effectively restrict the displacement and tilt of the inner lens in the vertical direction.

[0131] refer to Figure 12 In some embodiments, in the vertical direction along which the carrier 213 and the cover fitting part 211b are assembled in sequence, the height of the low beam main lens part 212 and / or the low beam widening lens part 112 is greater than the height of the inner reflective surface of the reflective body 211a.

[0132] The wall thickness of different parts of the covering mating part 211b is the same or the difference in wall thickness does not exceed 1 mm, and the covering mating part 211b is connected to the reflective body 211a through a stepped structure.

[0133] Specifically, with Figure 12 Taking the cooperation between the main inner lens unit 212a and the cover fitting part 211b as an example: the height of the main inner lens unit 212a is greater than the height of the reflective body 211a, which is beneficial to collect more light from the reflective body 211a in the height direction and can avoid the light from the reflective body 211a from leaking out and causing stray light.

[0134] With the height of the main inner lens unit 212a greater than the height of the inner reflecting surface of the reflective body 211a, different parts of the cover fitting part 211b are designed with equal wall thickness and connected to the reflective body 211a via a stepped structure. This eliminates the need for a smooth connection to the outer contour surface of the reflective body 211a, thus avoiding raising the outer contour surface of the reflective body 211a to the same height as the outer surface of the cover fitting part 211b. This prevents increasing the vertical thickness of the reflective body 211a and saves material costs. In actual manufacturing, the above-described structure in this embodiment can be formed by bending or stamping processes.

[0135] Furthermore, by adopting a stepped structure for connection, the overall space occupied by the main inner lens unit 212a and the low beam broadening reflector 111 can be further reduced. This will reduce the size of the entire optical module, and when installed inside the lamp, it will occupy less space inside the lamp and be more flexible in its arrangement. Especially in the context of current intelligent vehicle lights, more functions are integrated inside the lamp, and a smaller optical module can significantly reduce the layout difficulty of the internal structure of the entire lamp.

[0136] Of course, in other embodiments, with the use of a large-height inner lens, the cover fitting part 211b can also be directly and smoothly connected to the reflective body 211a. In this case, there is no need to design a stepped structure, but the mirror body thickness needs to be designed to be very large to match the large-height inner lens and the cover fitting part 211b. Obviously, this would require more profile material and the overall space occupied would be larger.
