Description

Technical Field

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

[0002] Cornering lights play a crucial role in automotive lighting systems. Due to their wider beam, they not only improve visibility in poor conditions such as fog, rain, or nighttime, but also provide auxiliary lighting at corners, better illuminating the road ahead and offering drivers a wider field of vision. Consequently, cornering lights are increasingly widely used in various vehicle types, including passenger cars and commercial vehicles. Especially in the fields of new energy vehicles and intelligent driving vehicles, cornering lights are increasingly incorporating intelligent technologies, such as low-speed assist, which automatically activates at low speeds to help drivers better see pedestrians, obstacles, or other vehicles on the roadside.

[0003] In existing technologies, vehicles requiring a wide beam pattern typically incorporate cornering light modules. Adding a cornering light module not only increases module cost but also necessitates installation, such as module brackets and trim rings, increasing assembly steps and costs. Furthermore, the integration of cornering lights with low beams becomes a significant challenge. Because there are no directly connecting parts between cornering lights and low beams, the tolerance chain is very long, resulting in large assembly tolerances. Therefore, controlling the integration of cornering lights and low beams in mass production is difficult, and implementing a separate dimming system for cornering lights would drastically increase costs. If the cornering lights are too low, vehicle occupants will experience a disconnect in the low beam, and the headlights will fail to illuminate the inner part of the curve when turning, increasing blind spots and posing a significant safety hazard. If the cornering lights are too high, they are likely to cause glare to oncoming vehicles and pedestrians and may also violate regulations.

[0004] There is currently a great deal of research on the integration of low beam headlights and cornering lights. For example, Chinese patent CN212456692U discloses an integrated high and low beam LED light source with cornering light function. This patent rigidly fixes the high and low beam modules and the cornering light module together, with the cornering light optical system and the high and low beam optical systems being independent. Moreover, the light-emitting surface of the overall module is discontinuous, with obvious steps visible. Another Chinese patent CN214700545U discloses an integrated high and low beam module. Although this patent has a continuous light-emitting surface, the reflector of the cornering light module is placed in front of the high and low beam reflectors, causing the cornering light reflector to significantly obstruct the high and low beams.

[0005] Therefore, there is an urgent need for a vehicle lighting module that integrates the cornering light module and the low beam module into one unit to meet the requirements of both the cornering light and the low beam shape. Utility Model Content

[0006] In view of the above-mentioned technical problems, this application provides an optical module, an automotive lamp and an automobile. This application can reduce the number of parts, greatly reduce costs, and at the same time meet the requirements of corner lights and low beam patterns.

[0007] To achieve the above objectives, the technical solution of this application is as follows: The first aspect of this application provides an optical module, including at least one low beam unit and at least one corner lamp unit.

[0010] In a preferred embodiment, when the optical module is installed on a vehicle, the front-to-back direction of the vehicle is the first direction, and the projection lengths of the low beam primary optical unit and the cornering lamp primary optical unit in the first direction at least partially overlap.

[0011] In a preferred embodiment, when the optical module is installed on a vehicle, the left-right direction of the vehicle is the second direction, the first direction and the second direction form a first plane, the low beam primary optical unit and the cornering lamp primary optical unit are arranged along the second direction, the projection of the light-emitting surface of the optical module on the first plane onto the second plane forms a first projection line, and on the first plane, there are parallel lines to the first projection line that pass through the projections of each of the low beam primary optical unit and the cornering lamp primary optical unit onto the first plane.

[0012] In a preferred embodiment, at least one of the near-beam primary optical units has a near-beam cutoff line structure, and at least one of the near-beam cutoff line structures has an inflection point.

[0013] In a preferred embodiment, in at least one of the low beam units, the low beam source is located within 10 mm of the focal point of the primary low beam optical unit, and the focal point of the secondary low beam optical unit is located within 10 mm of the low beam cutoff line structure.

[0014] In a preferred embodiment, the near-light secondary optical unit includes a mirror and / or a condenser. The near-beam cutoff line structure is located at the boundary of the reflector near the near-beam source; or The near-beam cutoff line structure is located on the light-emitting side of the concentrator.

[0015] In a preferred embodiment, the low beam secondary optical unit includes an inner low beam lens and an outer low beam lens, and the cornering lamp secondary optical unit includes an inner cornering lamp lens and an outer cornering lamp lens. The outer low beam lens and the outer cornering lamp lens are integrally formed. The low beam secondary optical unit and the cornering lamp secondary optical unit are adjusted in one or more ways such that when the optical module is installed on the vehicle, the light emitted from the cornering lamp secondary optical unit is projected onto the outside of the light emitted from the low beam secondary optical unit: The light-incident surface of the inner lens of the corner lamp has a different shape than the light-incident surface of the inner lens of the near beam. The light-emitting surface of the inner lens of the corner lamp has a different shape than the light-emitting surface of the inner lens of the near beam. The light-incident surface of the corner lamp outer lens has a different shape than that of the light-incident surface of the low-beam outer lens.

[0016] In a preferred embodiment, the light-emitting surfaces of the low-beam inner lens and the corner lamp inner lens are formed as smooth curved surfaces or planes with continuous curvature; and / or The light-incident surfaces of the low-beam outer lens and the corner lamp outer lens are formed as smooth curved surfaces or planes with continuous curvature.

[0017] In a preferred embodiment, the system further includes a circuit board and a heat sink, wherein the low beam unit and the corner lamp unit share the circuit board and / or the heat sink.

[0018] Based on the same concept, a second aspect of this application provides an automotive lighting fixture, including the optical module described in any embodiment.

[0019] Based on the same concept, a third aspect of this application provides an automobile, including the aforementioned automobile lights.

[0020] Because this application adopts the above technical solution, it has the following advantages and positive effects compared with the prior art: The optical module of this application integrates the corner lamp secondary optical unit and the low beam secondary optical unit into a single molded component, as well as the corner lamp primary optical unit and the low beam primary optical unit into a single molded component. Compared to existing independent modules for low beam and corner lamps, this reduces the number of internal and external mounting and positioning parts of the optical module. Furthermore, the integrated optical module for low beam and corner lamps can share a dimming structure, thereby significantly reducing costs, saving overall lamp space, and avoiding the problem of low beam and corner lamp beam pattern alignment caused by large assembly tolerances between the corner lamp and low beam modules. Compared to existing modules that integrate high / low beam and corner lamps but still have partially independent optical components, this also reduces mounting parts, lowers costs, and facilitates the assembly of internal components. Simultaneously, because the corner lamp primary optical unit is shared with the low beam primary optical unit, and the corner lamp secondary optical unit and the low beam secondary optical unit are integrated into a single secondary optical unit, problems such as beam pattern alignment and beam pattern obstruction caused by misalignment or misalignment of the corner lamp and low beam optical components are avoided.

[0021] Furthermore, the light-emitting surfaces of the optical module, namely the light-emitting surfaces of the low beam secondary optical unit and the corner lamp secondary optical unit, are connected to form a smooth curved surface with continuous curvature. The light-emitting surfaces are smooth and continuous, and there are no twisted or bent surfaces at the connection between the low beam secondary optical unit and the corner lamp secondary optical unit. From the appearance, it is a unified module without obvious functional divisions, and the style of the entire lamp is more unified.

Detailed Implementation

[0025] The following detailed description, in conjunction with the accompanying drawings and specific embodiments, provides a further detailed description of an optical module, automotive lighting fixture, and automobile according to this application. The same or similar reference numerals denote the same or similar components. The following description of this application with reference to the accompanying drawings is intended to explain the overall concept of this application and should not be construed as a limitation thereof. Furthermore, in the following detailed description, numerous specific details are set forth for ease of explanation to provide a full understanding of the embodiments disclosed herein. It will then become apparent that one or more embodiments may be practiced without these specific details.

[0026] Example 1 like Figure 1-7 As shown, an optical module includes at least one near beam unit 1 and at least one corner lamp unit 2. Figure 1-4 The optical module shown exemplarily has 6 low beam units 1 and 2 corner lamp units 2. The number of low beam units 1 and corner lamp units 2 in the optical module of this application is not limited thereto.

[0027] The low beam unit 1 includes a low beam source, a primary low beam optical unit 101, and a secondary low beam optical unit 102. The light emitted by the low beam source passes through the primary low beam optical unit 101 and enters the secondary low beam optical unit 102, and is emitted through the secondary low beam optical unit 102 to form a low beam pattern. The corner lamp unit 2 includes a corner lamp light source, a corner lamp primary optical unit 201 and a corner lamp secondary optical unit 202. The light emitted by the corner lamp light source is emitted through the corner lamp primary optical unit 201 and then enters the corner lamp secondary optical unit 202, and is emitted through the corner lamp secondary optical unit 202 to form a corner lamp light pattern. Among them, the primary optical unit 101 for low beam and the primary optical unit 201 for corner lamp are integrally formed parts, and the secondary optical unit 102 for low beam and the secondary optical unit 202 for corner lamp are integrally formed parts.

[0028] Assuming the light emitted by the low beam secondary optical unit 102 is directed towards the front of the vehicle, the cornering lamp secondary optical unit 202, mounted on the left or right side of the vehicle according to the optical module, emits light in a direction corresponding to its mounting position towards the front left or front right of the vehicle. This allows the light emitted by the cornering lamp secondary optical unit to be directed towards the front left or front right of the vehicle (i.e., outside the projection position of the light emitted by the low beam secondary optical unit 102), achieving a beam spread effect. This expands the illumination range to the side and front, compensating for the insufficient illumination angle of the low beam headlights. When driving on curves, this provides illumination to the inside of the curve, thus offering the driver a wider field of vision and improving driving safety. Figure 2 For example, the optical module is installed on the left side of the vehicle. The light emitted by the low beam secondary optical unit 102 is directed towards the front of the vehicle, while the light emitted by the cornering lamp secondary optical unit 202 to the right of the low beam secondary optical unit 102 is directed towards the front left side of the vehicle. Figure 2 This application is merely illustrative and is not intended to be limiting.

[0029] This embodiment integrates the corner lamp secondary optical unit and the low beam secondary optical unit into a single molded component, as well as the corner lamp primary optical unit and the low beam primary optical unit. Compared to existing independent low beam and corner lamp modules, this reduces the number of internal and external mounting and positioning parts within the optical module. Furthermore, the integrated low beam and corner lamp optical modules can share a dimming structure, significantly reducing costs and saving overall lamp space while avoiding issues related to the alignment of low beam and corner lamp beam patterns caused by large assembly tolerances between the corner lamp and low beam modules. Compared to existing modules that integrate high / low beam and corner lamps but still have partially independent optical components, this also reduces mounting parts, lowers costs, and facilitates the assembly of internal components. Simultaneously, because the corner lamp primary optical unit and the low beam primary optical unit are shared, and the corner lamp secondary optical unit and the low beam secondary optical unit are integrated into a single secondary optical unit, problems such as beam pattern alignment and obstruction caused by misalignment or misalignment of the corner lamp and low beam optical components are avoided.

[0030] In one embodiment, the light-emitting surface of the low beam secondary optical unit 102 and the light-emitting surface of the cornering lamp secondary optical unit 202 are connected to form a smooth curved surface with continuous curvature. That is, the light-emitting surface 11 of the optical module is smooth and continuous, and there is no twisted or bent surface at the connection between the low beam secondary optical unit 102 and the cornering lamp secondary optical unit 202. From the appearance, it is a unified module without obvious functional divisions, and the style of the whole lamp is more unified; at the same time, the shape of the light-emitting surface can follow the extension trend of the headlight shape.

[0031] In one embodiment, the optical axis of the cornering lamp primary optical unit 201 and the optical axis of the low beam primary optical unit 101 are at an angle. This design results in the light rays emitted from the cornering lamp primary optical unit 201 and the low beam primary optical unit 101 having different directions. Ultimately, the light rays emitted by the cornering lamp secondary optical unit 202 are directed towards the front side of the vehicle to form the cornering lamp pattern, while the light rays emitted by the low beam secondary optical unit 102 are directed towards the front of the vehicle to form the low beam pattern.

[0032] In a preferred embodiment, when the optical module is installed on a vehicle, assuming the vehicle's longitudinal direction is the first direction 9, the projected lengths of the low beam primary optical unit 101 and the cornering lamp primary optical unit 201 in the first direction 9 at least partially overlap. That is, the low beam primary optical unit 101 and the cornering lamp primary optical unit 201 are projected onto the first direction 9, their projected lengths at least partially overlap, and the low beam primary optical unit 101 and the cornering lamp primary optical unit 201 are integrated into one unit. In other words, there is no separation or spacing between the low beam primary optical unit 101 and the cornering lamp primary optical unit 201 in the first direction 9. Therefore, the low beam primary optical unit 101 and the cornering lamp primary optical unit 201 will not obstruct each other in the first direction 9.

[0033] Furthermore, the left-right direction of the vehicle is the second direction 10, and the plane formed by the first direction 9 and the second direction 10 is the first plane. The low beam primary optical unit 101 and the cornering lamp primary optical unit 201 are arranged along the second direction 10. Specifically, the phrase "arranged along the second direction 10" in this application means arranged approximately along the second direction 10. The low beam primary optical unit 101 and the cornering lamp primary optical unit 201 may be staggered relative to each other in the second direction 10, or the angle between the arrangement direction of the low beam primary optical unit 101 and the cornering lamp primary optical unit 201 and the second direction 10 may be less than 20 degrees. Furthermore, the projection of the intercept of the light-emitting surface 11 of the optical module in the second direction 10 onto the first plane forms a first projection line. On the first plane, there exist parallel lines to the first projection line that pass through the projections of each low beam primary optical unit 101 and the cornering lamp primary optical unit 201 onto the first plane. Therefore, the primary optical unit 101 of the low beam unit 1 and the primary optical unit 201 of the corner lamp unit 2 are arranged along the trend of the light-emitting surface 11 of the optical module, and the arrangement direction is close to the trend of the light-emitting surface 11 of the optical module, which further avoids the light blocking caused by the large drop between adjacent primary optical units.

[0034] The upper boundary of the near beam pattern is called the cutoff line. To control the beam pattern, the cutoff line of the projected beam pattern must have the required shape. Therefore, the primary optical unit 101 of the near beam needs to be designed to have a cutoff line structure corresponding to the cutoff line, that is, the primary optical unit 101 of the near beam has a near beam cutoff line structure 7. At least one near beam unit 1's near beam cutoff line structure 7 has an inflection point.

[0035] In some variations, if the corner lamp light pattern requires a cutoff line, the primary optical unit 201 of the corner lamp may also have a corner lamp cutoff line structure 8, and at least one corner lamp unit 2's corner lamp cutoff line structure 8 has no inflection point.

[0036] Furthermore, in at least one low beam unit 1, the low beam source is located within a 10 mm range of the focal point of the primary low beam optical unit 101. Specifically, the low beam source being located within a 10 mm range of the focal point of the primary low beam optical unit 101 includes the low beam source being located at the focal point of the primary low beam optical unit 101; the focal point of the secondary low beam optical unit 102 is located within a 10 mm range of the low beam cutoff line structure 7. Specifically, the focal point of the secondary low beam optical unit 102 being located within a 10 mm range of the low beam cutoff line structure 7 includes the focal point of the secondary low beam optical unit 102 being located at the low beam cutoff line structure 7.

[0037] The secondary low beam optical unit 102 images its focal point, thus setting the focal point of the secondary low beam optical unit 102 at the low beam cutoff structure 7, enabling the secondary low beam optical unit 102 to image the low beam cutoff structure 7 and form a low beam pattern with a corresponding bright and dark cutoff line. The low beam source is located at the focal point of the primary low beam optical unit 101, ensuring an ideal energy distribution after the low beam source reaches the primary low beam optical unit 101. Therefore, when the secondary low beam optical unit 102 images the primary low beam optical unit 101 illuminated by the low beam source, it also achieves an ideal energy distribution. Preferably, the low beam source is an LED, and the primary low beam optical unit 101 has a parabolic or near-parabolic reflective surface. Thus, the LED and the near-parabolic reflector naturally form a uniformly transitioning light distribution, achieving headlight road surface uniformity without excessive surface adjustments.

[0038] In some embodiments, the low beam primary optical unit 101 is a reflector and / or a condenser. The low beam cutoff line structure 7 is located on the reflector near the boundary of the low beam source; or the low beam cutoff line structure 7 is located on the light-emitting side of the condenser. In some embodiments, the corner lamp primary optical unit 201 is a reflector and / or a condenser. If the low beam primary optical unit 101 is a reflector, the corner lamp primary optical unit 201 is also a reflector; if the low beam primary optical unit 101 is a condenser, the corner lamp primary optical unit 201 is also a condenser.

[0039] In another preferred embodiment, the low beam secondary optical unit 102 includes a low beam inner lens 1021 and a low beam outer lens 1022 arranged sequentially along the optical axis. The corner lamp secondary optical unit 202 includes a corner lamp inner lens 2021 and a corner lamp outer lens 2022 arranged sequentially along the optical axis. The low beam outer lens 1022 and the corner lamp outer lens 2022 are integrally formed, as are the low beam inner lens 1021 and the corner lamp inner lens 2021. That is, the low beam secondary optical unit 102 and the corner lamp secondary optical unit 202 are integrally formed, mainly referring to the connection relationship of the optical elements between the low beam unit and the corner lamp unit. In embodiments where the low beam secondary optical unit 102 includes a low beam inner lens 1021 and a low beam outer lens 1022, and the cornering lamp secondary optical unit 202 includes a cornering lamp inner lens 2021 and a cornering lamp outer lens 2022, the low beam secondary optical unit 102 and the cornering lamp secondary optical unit 202 can be integrally formed as follows: the low beam outer lens 1022 and the cornering lamp outer lens 2022 are integrally formed, the low beam inner lens 1021 and the cornering lamp inner lens 2021 are integrally formed, and the integrally formed component of the low beam outer lens 1022 and the cornering lamp outer lens 2022 is independent of the integrally formed component of the low beam inner lens 1021 and the cornering lamp inner lens 2021. In some variations, the low beam secondary optical unit 102 and the corner lamp secondary optical unit 202 can be integrally formed, or the integrally formed part of the low beam outer lens 1022 and the corner lamp outer lens 2022 and the integrally formed part of the low beam inner lens 1021 and the corner lamp inner lens 2021 can be formed into an integrally formed part through an integral connecting part at the edge.

[0040] The low beam secondary optical unit 102 and the cornering lamp secondary optical unit 202 are adjusted in one or more ways such that when the optical module is mounted on the vehicle, the light emitted from the cornering lamp secondary optical unit 202 is projected outside the light emitted from the low beam secondary optical unit 102: The light-incident surface of the inner lens 2021 of the corner lamp has a different surface shape than that of the light-incident surface of the inner lens 1021 of the low beam; The light-emitting surface of the inner lens 2021 of the corner lamp has a different shape than that of the light-emitting surface of the inner lens 1021 of the low beam; The light-incident surface of the corner lamp outer lens 2022 has a different shape than that of the light-incident surface of the low beam outer lens 1022.

[0041] The light from the low beam source is emitted through the low beam primary optical unit 101 and then enters the low beam inner lens 1021. After being refracted by the low beam inner lens 1021, the light emitted enters the low beam outer lens 1022. The light pattern emitted by the low beam outer lens 1022 is the low beam light pattern. The light from the corner lamp source is emitted through the corner lamp primary optical unit 201 and then enters the corner lamp inner lens 2021. After being refracted by the corner lamp inner lens 2021, the light emitted enters the corner lamp outer lens 2022. The light pattern emitted by the corner lamp outer lens 2022 is the corner lamp light pattern.

[0042] In some variations, the low beam secondary optical unit 102 may include only one low beam lens, and the corner lamp secondary optical unit 202 may include only one corner lamp lens. The light-incident surface of the corner lamp lens has a different surface shape than the light-incident surface of the low beam lens, and the light-exit surface of the corner lamp lens and the light-exit surface of the low beam lens are formed as smooth curved surfaces with continuous curvature.

[0043] Under the premise of flattening the overall automotive headlight module, the combination of inner and outer lenses can, on the one hand, reduce the thickness of the lens along the optical axis to reduce the lens weight, and since the cost of two thin lenses is lower than the cost of one thick lens, the module cost can be reduced; on the other hand, the two lenses can increase the adjustable optical surface, thus making the lens design more flexible.

[0044] Furthermore, the light-emitting surface of the low beam inner lens 1021 and the light-emitting surface of the corner lamp inner lens 2021 are formed as smooth curved surfaces or planes with continuous curvature; and / or the light-incident surface of the low beam outer lens 1022 and the light-incident surface of the corner lamp outer lens 2022 are formed as smooth curved surfaces or planes with continuous curvature.

[0045] Specifically, such as Figure 1-4 As shown in Figures 6-7, both the low-beam primary optical unit and the corner lamp primary optical unit are reflectors. Light emitted from the low-beam source is reflected by the low-beam reflector 101 and enters the low-beam inner lens 1021. Light rays exiting the low-beam inner lens 1021 enter the low-beam outer lens 1022 and exit after refraction. Light emitted from the corner lamp source is reflected by the corner lamp reflector 201 and enters the corner lamp inner lens 2021. Light rays exiting the corner lamp inner lens 2021 enter the corner lamp outer lens 2022 and exit after refraction. Figure 2As shown in the optical path diagram of this embodiment, the optical axis of the corner lamp reflector 201 is deflected relative to the optical axis of the low beam reflector 101, causing the light rays passing through the corner lamp reflector 201 to be deflected compared to the light rays passing through the low beam reflector 101. When the vehicle is in use, the corner lamp light sources do not need to be turned on during normal driving. When the vehicle is driving on a curve, the corner lamp light sources on the corresponding sides can be turned on. For example, when the vehicle is turning left, the corner lamp light source of the left headlight can be turned on to increase the illumination range on the left side; when the vehicle is turning right, the corner lamp light source of the right headlight can be turned on to increase the illumination range on the right side.

[0046] In another preferred embodiment, the optical module also includes a circuit board 3 and a heat sink 6. The low beam unit 1 and the corner lamp unit 2 share the circuit board 3 and / or the heat sink 6, thereby further reducing the number of parts and assembly steps.

[0047] like Figure 1-4 As shown, the optical module has six low-beam units 1 and two corner lamp units 2. The corner lamp units 2 can be located anywhere in the optical module and can be arbitrarily distributed among the six low-beam units 1. In this embodiment, the two corner lamp units 2 are located on the rightmost side of the second direction 10. The low-beam units 1 and the corner lamp units 2 share a circuit board 3 and a heat sink 6. The low-beam light source and the corner lamp light source are mounted on a circuit board 3, and the circuit board 3 and the heat sink 6 are fixedly connected. The optical module also includes a primary optical unit bracket 4 and a secondary optical unit bracket 5. The corner lamp primary optical unit 201 and the low-beam primary optical unit 101 are mounted on the primary optical unit bracket 4, and the corner lamp secondary optical unit 202 and the low-beam secondary optical unit 102 are mounted on the secondary optical unit bracket 5. The primary optical unit bracket 4 and the secondary optical unit bracket 5 are fixedly connected to the heat sink 6. This application is not limited to this; the secondary optical unit bracket 5 can also be fixedly connected to the primary optical unit bracket 4, and then fixedly connected to the heat sink 6 through the primary optical unit bracket 4. The primary optical unit bracket 4 can be integrally formed with the low beam primary optical unit 101 and the corner lamp primary optical unit 201.

[0049] Example 3 This embodiment provides a car, including the car lamp of embodiment 2, to have the same technical effect as the car lamp.

[0050] The embodiments of this application have been described in detail above with reference to the accompanying drawings, but this application is not limited to the above embodiments. Even if various changes are made to this application, if these changes fall within the scope of the claims of this application and their equivalents, they shall still fall within the protection scope of this application.
