Description

Technical Field

[0001] This application relates to the field of vehicles, and in particular to a lens assembly for a vehicle and a vehicle. Background Technology

[0002] In related technologies, automotive front fog lights employ a dual-lens optical system to achieve wide-range near-ground illumination, controlling the light pattern distribution in different directions through the combination of two lens bodies. However, in existing technologies, the angle between the optical axes of the two lens bodies is not properly set, resulting in a clear boundary between light and dark areas in the direction of emission. This light pattern stratification not only reduces the uniformity of illumination in foggy weather but also easily causes visual interference for drivers in complex road conditions, affecting driving safety. Therefore, how to avoid light pattern stratification is the technical problem to be solved in this application. Utility Model Content

[0003] This application aims to at least address one of the technical problems existing in the prior art. To this end, one objective of this application is to provide a lens assembly for vehicles that can avoid light pattern layering.

[0006] According to the embodiments of this application, the lens assembly for vehicles allows the lens body to move radially during installation due to the gap between the fastener and the first mounting hole, thus creating an adjustable degree of freedom. The lens body can move up and down or left and right, changing the vertical tilt angle or horizontal offset of the optical axis. By adjusting the position of the lens body, the optical axis angle and relative position of the two lenses can be corrected, eliminating abrupt boundary lines in the light distribution, forming a uniform and continuous illumination pattern, avoiding the phenomenon of light pattern layering, and improving the safety of fog lamp illumination in foggy weather.

[0007] According to some embodiments of this application, a lens assembly for a vehicle includes a fastener comprising: a connecting portion that engages with a first mounting portion and passes through a first mounting hole; and an abutting portion disposed at one end of the connecting portion and coaxial with the connecting portion, the abutting portion abutting against the side of the lens body opposite to the base; wherein the diameter of the first mounting hole is L1, the outer diameter of the connecting portion is L2, and the outer diameter of the abutting portion is L3, and satisfies L2 < L1 < L3.

[0008] According to some embodiments of the present application, in a lens assembly for a vehicle, the aperture of the first mounting hole gradually decreases in the direction away from the base, and the aperture of the first mounting hole on the side away from the base is L4, which satisfies L4 < L3.

[0009] According to some embodiments of the present application, a lens assembly for a vehicle has a first mounting portion having a mating cavity for receiving the connecting portion, the mating cavity having an opening facing the connecting portion, at least a portion of the inner wall of the mating cavity having an internal thread, and at least a portion of the outer wall of the connecting portion having an external thread.

[0010] According to some embodiments of this application, a lens assembly for a vehicle includes: a lampshade that protrudes away from the base in the thickness direction; a first mounting plate and a second mounting plate disposed on both sides of the lampshade; the first mounting plate having at least one first mounting hole and the second mounting plate having at least one first mounting hole; wherein the first mounting plate and the second mounting plate are staggered in the thickness direction.

[0011] According to some embodiments of this application, a lens assembly for a vehicle has a light-emitting element disposed on a circuit board, and at least a portion of the lampshade covers the light-emitting element.

[0012] According to some embodiments of the present application, in a lens assembly for a vehicle, the first mounting plate of each lens body is disposed on the same side of the lens body, and the cross-sectional dimension of the first mounting plate is larger than the cross-sectional dimension of the second mounting plate.

[0013] According to some embodiments of this application, a lens assembly for a vehicle has two adjacent lens bodies with first mounting plates spaced apart from each other, one of the first mounting plates having a reinforcing plate extending toward the other first mounting plate, the edge of the reinforcing plate being spaced apart from at least a portion of the other first mounting plate.

[0014] According to some embodiments of this application, a lens assembly for a vehicle has a rotating column formed on a base. The rotating column is disposed in the middle section of the base and is located on at least a portion of the outer periphery of the base and extends in a direction away from the base. The rotating column is adapted to cooperate with a vehicle body.

[0015] The vehicle according to an embodiment of this application is briefly described below.

[0016] The vehicle according to the embodiments of this application includes the lens assembly of any of the above embodiments. Since the vehicle according to this embodiment is equipped with the lens assembly of any of the above embodiments, the vehicle according to this application has a lens assembly that can be finely adjusted. The position adjustment of the lens body is flexible, and due to the gap between the fastener and the first mounting hole, the position adjustment structure occupies little space and does not increase the cost or outline size of the headlight. When driving in foggy weather, the illumination pattern of the front fog light of the vehicle using this lens assembly is more uniform and continuous. There is no longer a clear dividing line between light and dark, but a smooth transition light field is formed in the near-ground and far-ground areas, which effectively improves the light utilization rate and greatly improves the lighting effect of the vehicle in bad weather. The elimination of light pattern layering phenomenon greatly reduces the visual interference caused by light pattern layering. The uniform illumination pattern can more clearly and accurately observe the road ahead, obstacles and other vehicles, avoiding visual fatigue and judgment errors caused by sudden changes in light. The adjustability of the lens assembly can also adapt to the influence of different fog concentrations, vehicle load and other factors on the headlight pitch angle, always maintaining the best lighting state, further enhancing the safety of vehicle driving.

[0029] The embodiments of this application are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this application, and should not be construed as limiting this application.

[0030] The following is for reference. Figures 1-3 A lens assembly 100 for a vehicle according to an embodiment of this application is described.

[0031] According to an embodiment of this application, a lens assembly 100 for a vehicle includes a base 1, a circuit board 2, a lens body 3, and a fastener 4. The base 1 is provided with a first mounting portion 11. The circuit board 2 is disposed on one side of the base 1 and avoids the first mounting portion 11. The lens body 3 is constructed in multiple parts and is connected to the circuit board 2 respectively. Each lens body 3 has a first mounting hole 31 corresponding to the first mounting portion 11. The fastener 4 passes through the first mounting hole 31. One end of the fastener 4 abuts against the lens body 3, and the other end of the fastener 4 is connected to the first mounting portion 11. A gap 5 exists between the fastener 4 and the first mounting hole 31 to facilitate adjustment of the position of the lens body 3 relative to the base 1.

[0032] In related technologies, automotive front fog lights employ a dual-lens optical system to achieve wide-range near-ground illumination, controlling the light pattern distribution in different directions through the combination of two lens bodies 3. However, in existing technologies, the angle between the optical axes of the two lens bodies 3 is not properly set, resulting in a clear boundary between light and dark in the vertical direction. This light pattern layering phenomenon not only reduces the uniformity of fog lighting but also easily causes visual interference for drivers in complex road conditions, affecting driving safety.

[0033] It should be noted that an unreasonable optical axis angle between the two lenses can easily cause the light rays emitted from the two lens bodies 3 to cover independent areas in the emission direction, lacking overlap and forming a light-dark boundary. In a rigid connection, the position of the lens body 3 is fixed by mechanical holes, and the optical axis angle cannot be changed after assembly. According to the lens assembly 100 for vehicles in this application embodiment, the gap 5 between the fastener 4 and the first mounting hole 31 allows the lens body 3 to move slightly radially along the fastener 4 during installation. The lens body 3 can move up and down or left and right, causing the vertical tilt angle or horizontal offset of the optical axis. This makes the position of the lens body 3 relative to the base 1 no longer absolutely fixed, providing a physical possibility for subsequent optical axis optimization. By adjusting the position of the lens body 3, the optical axis angle and relative position of the two lenses can be corrected, allowing the light distribution to overlap.

[0034] It is understandable that if the optical axis of the lens body 3 is originally horizontal, it can be tilted downward slightly through the gap 5 so that its light coverage area overlaps with the near-ground area of ​​the adjacent lens body 3; or the adjacent lens body 3 can be adjusted to move upward slightly to expand the illumination height and connect with the light pattern of the lens body 3. If the light pattern of the two lenses is offset in the width direction, the lens body 3 can be moved laterally through the gap 5 so that the centers of the light spots of the two are aligned to avoid one side being too bright.

[0035] Furthermore, the lens body 3 includes a first mirror and a second mirror. The light pattern coverage area of ​​the first mirror is the first region, and the light pattern coverage area of ​​the second mirror is the second region. The first region and the second region do not overlap or overlap insufficiently, and there is a difference in light intensity at the boundary, forming a dividing line. By setting a gap 5, the position of the lens body 3 relative to the base 1 is adjusted. After adjustment, the lens body 3 is moved through the gap 5 so that the first region and the second region partially overlap. In the overlapping area, the light rays of the two lens bodies 3 are superimposed, and the light intensity smoothly transitions from at least part of the edge of the first region to at least part of the edge of the second region, eliminating the light and dark dividing line and avoiding light pattern layering.

[0036] In short, the gap 5 between the fastener 4 and the first mounting hole 31 allows the lens body 3 to move radially during installation, creating an adjustable degree of freedom. The lens body 3 can move up and down or left and right, changing the vertical tilt angle or horizontal offset of the optical axis. By adjusting the position of the lens body 3, the optical axis angle and relative position of the two lenses can be corrected, eliminating abrupt boundary lines in the light distribution, forming a uniform and continuous illumination pattern, avoiding the phenomenon of light pattern layering, and improving the safety of fog lamp illumination in foggy weather.

[0037] According to some embodiments of this application, a lens assembly 100 for a vehicle includes a fastener 4 comprising a connecting portion 41 and an abutting portion 42. The connecting portion 41 engages with a first mounting portion 11 and passes through a first mounting hole 31. The abutting portion 42 is disposed at one end of the connecting portion 41 and is coaxial with the connecting portion 41. The abutting portion 42 abuts against the side of the lens body 3 facing away from the base 1. The diameter of the first mounting hole 31 is L1, the outer diameter of the connecting portion 41 is L2, and the outer diameter of the abutting portion 42 is L3, satisfying that L2 < L1 < L3.

[0038] Since the outer diameter L2 of the connecting part 41 is smaller than the aperture L1 of the first mounting hole 31, there is a gap 5 between them, which provides a key adjustment space for the installation of the lens body 3. During the assembly process, the lens body 3 can be slightly moved up and down and left and right using this gap 5. When it is found that the optical axis angle of the two lenses is unreasonable, resulting in light pattern separation, the optical axis angle can be finely adjusted by moving the lens laterally to optimize the light pattern separation, so that the lens assembly can adapt to the installation requirements of different vehicle models. It can also be calibrated after installation according to actual use to ensure that the lens is always in the best working state and improve the lighting effect. At the same time, the outer diameter L3 of the abutment part 42 is larger than the aperture L1 of the first mounting hole 31, so that the abutment part 42 can press against the side of the lens body 3 away from the base 1 with a large area. When the fastener 4 connects and fixes the lens body 3 to the base 1, the abutment part 42 and the lens body 3 form a surface contact, avoiding the problem of the lens body 3 being displaced due to vibration and bumps during vehicle operation caused by insufficient point contact or line contact connection strength.

[0039] During assembly, the L2 < L1 dimension reduces installation difficulty. There's no need to align the connecting part 41 with the first mounting hole 31; the connecting part 41 can simply pass through the first mounting hole 31 to complete the initial lens installation. Afterward, based on actual optical pattern test results, the lens position is adjusted using the gap. This "install first, adjust later" approach significantly shortens assembly time. Simultaneously, L1 < L3 ensures that the abutment part 42 can fix the lens after adjustment, reducing assembly errors caused by repeated adjustments and improving assembly accuracy. This, in turn, enhances overall production efficiency and reduces production costs.

[0040] When problems such as abnormal light patterns occur during the use of the lens assembly, it may be necessary to readjust the lens position. In this case, because there is a gap 5 between the fastener 4 and the first mounting hole 31, it is not necessary to disassemble the entire assembly. Simply loosen the fastener 4 to readjust the lens. After adjustment, tighten the fastener 4 again, using the large area of ​​the abutment part 42 for pressure fixation, reducing maintenance time and labor costs. Furthermore, if the lens is damaged due to collision or other reasons and needs replacement, the fastener 4 can be easily removed to quickly replace the lens, improving the maintainability of the lens assembly. The size design of the fastener 4 makes the lens assembly 3 more adaptable and compatible. Different car models have different headlight installation requirements; the adjustment gap formed by L2 < L1 can accommodate various installation angles and positions. At the same time, even for different batches of products of the same car model, even with certain manufacturing tolerances, this gap 5 can be used for compensation, ensuring that the lens assembly 100 can be installed normally and function properly.

[0041] Meanwhile, the outer diameter L3 of the abutment part 42 is larger than the diameter L1 of the first mounting hole 31, playing a crucial role in fixing the lens body 3 after it has been adjusted to the appropriate position. When the lens body 3 is connected to the base 1 by the fastener 4, the abutment part 42 can cover the first mounting hole 31 and abut against the side of the lens body 3 away from the base 1, forming a large area of ​​pressure. Compared with small-area point contact or line contact, the large area of ​​abutment can provide a more uniform and stable pressure distribution, fixing the lens body 3 in the adjusted position. The friction between the abutment part 42 and the lens body 3, as well as the limiting effect on the lens body 3, can effectively prevent the lens body 3 from shifting, ensuring that the lens body 3 always maintains the correct installation position during use, maintains the optimized light pattern distribution, and ensures the stability and consistency of the lighting effect.

[0042] According to some embodiments of the present application, in a lens assembly 100 for a vehicle, the aperture of the first mounting hole 31 gradually decreases in the direction away from the base 1, and the aperture of the first mounting hole 31 on the side away from the base 1 is L4, which satisfies L4 < L3.

[0043] It should be noted that the first mounting hole 31 has a tapered structure with a gradually decreasing diameter, and L4 < L3, which means that the abutting part 42 abuts against the side of the first mounting hole 31 away from the base 1. Since L4 < L3, the abutting part 42 forms a larger area of ​​pressure against the side of the first mounting hole 31 away from the base 1. The edge of the abutting part 42 is tightly fitted with the inner wall at the L4 diameter, forming an annular pressure area. At the same time, due to the tapered design of the first mounting hole 31, the position of the lens body 3 is first adjusted by using the gap 5 between the connecting part 41 and the larger diameter hole, and then the abutting part 42 is abutted against the side of the first mounting hole 31 away from the base 1 by applying appropriate force to achieve fixation. This operation of adjusting first and then tightening does not require complicated auxiliary tools, which improves production efficiency while ensuring installation quality.

[0044] According to some embodiments of the present application, a lens assembly 100 for a vehicle has a first mounting portion 11 having a mating cavity 12 for receiving a connecting portion 41. The mating cavity 12 has an opening 13 facing the connecting portion 41. An internal thread is formed on at least a portion of the inner wall of the mating cavity 12, and an external thread is formed on at least a portion of the outer wall of the connecting portion 41.

[0045] The mating cavity 12 in the first mounting part 11 is connected to the connecting part 41 by a thread. Through the rotational characteristics of the thread, the position of the lens body 3 can be fixed and the mating gap 5 can be finely adjusted. During the installation process, the installer can rotate the connecting part 41 to the mating cavity 12. At this time, the first mounting hole 31 is restricted to the fastener 4. After the position of the lens body 3 is adjusted, the connecting part 41 continues to rotate into the mating cavity 12. At this time, the pressure between the abutting part 42 and the first mounting hole 31 increases, and the position of the lens body 3 is limited.

[0046] According to some embodiments of this application, a lens assembly 100 for a vehicle includes a lens body 3 comprising a lampshade 32, a first mounting plate 33, and a second mounting plate 34. The lampshade 32 protrudes away from the base 1 in the thickness direction. The first mounting plate 33 and the second mounting plate 34 are disposed on both sides of the lampshade 32. The first mounting plate 33 is provided with at least one first mounting hole 31, and the second mounting plate 34 is provided with at least one first mounting hole 31. The first mounting plate 33 and the second mounting plate 34 are staggered in the thickness direction.

[0047] The lampshade 32 protrudes away from the base 1 in the thickness direction, forming a three-dimensional structure, which expands the internal space of the lampshade 32, providing an installation area for the light source, while changing the light emission path. The protruding curved surface of the lampshade 32 can serve as a secondary optical element to refract and scatter the light emitted by the light source. The surface of the lampshade 32 can converge the light towards the ground, enhancing the intensity of near-distance illumination, so that a single lens body 3 can achieve wide-angle light distribution and simplify the optical structure.

[0048] The first mounting plate 33 and the second mounting plate 34 are located on both sides of the lamp cover 32 and are staggered in the thickness direction. They are offset in the horizontal direction, which makes the mounting hole positions spatially misaligned. The staggered arrangement makes the fixing points dispersed in space. When the vehicle vibrates, the stress on each mounting hole cancels each other out, avoiding overload of a single fixing point and improving the connection strength between the mounting plate and the base 1.

[0049] According to some embodiments of this application, a lens assembly 100 for a vehicle has a light-emitting element provided on a circuit board 2, and at least a portion of a lamp cover 32 covers the light-emitting element.

[0050] The lampshade 32 at least partially covers the light-emitting element. The curved surface of the inner wall of the lampshade 32 can refract or reflect the light emitted by the light-emitting element in a directional manner. The inner wall of the lampshade 32 can be a parabolic surface or a free-form surface to converge the light emitted by the light-emitting element. If the light emitted by the light-emitting element is not effectively constrained by the lampshade 32, it may scatter to non-illuminated areas, forming stray light and reducing the effective light utilization rate. The fully enclosed or partially covered structure of the lampshade 32 can limit the light to the target illumination direction and reduce ineffective dispersion in all directions. The curved surface at the bottom of the lampshade 32 can reflect the downward light to the road surface and avoid glare caused by upward illumination.

[0051] According to some embodiments of the present application, in a lens assembly 100 for a vehicle, a first mounting plate 33 of each lens body 3 is disposed on the same side of the lens body 3, and the cross-sectional dimension of the first mounting plate 33 is larger than the cross-sectional dimension of the second mounting plate 34.

[0052] The first mounting plates 33 of the lens body 3 are concentrated on the same side, which standardizes the installation direction and avoids the increased space occupation caused by the mounting plates being scattered on both sides. This facilitates a compact arrangement in the vehicle's lamp housing. The cross-section of the first mounting plate 33 is larger than that of the second mounting plate 34, forming an asymmetrical structure. The first mounting plate 33 serves as the main support and light-shielding component, while the second mounting plate 34 provides auxiliary fixation. Together, they achieve the dual goals of mechanical balance and optical control. Since the first mounting plate 33 is larger and on the same side as the light-emitting element, its edge can extend to the front of the lamp cover 32, directly blocking stray light from the light-emitting element to that side. The first mounting plate 33 can intercept light overflowing from the light-emitting element, reducing glare. The height and width of the first mounting plate 33 determine the blocking range. The edge shape of the first mounting plate 33 can form a clear light cutoff line, limiting the light to the target area.

[0053] According to some embodiments of the present application, a lens assembly 100 for a vehicle has two adjacent lens bodies 3 with first mounting plates 33 spaced apart from each other. One of the first mounting plates 33 is provided with a reinforcing plate 35 extending toward the other first mounting plate 33, and the edge of the reinforcing plate 35 is spaced apart from at least a portion of the other first mounting plate 33.

[0054] Understandably, the interior of the vehicle's headlight compartment is compact, containing a radiator, wiring harness, and other lighting components. The first mounting plates 33 of adjacent lens bodies 3 are spaced apart from each other, and the edge of the reinforcing plate 35 is spaced from another mounting plate, providing ample space for other components. During installation, this effectively prevents collisions or compression with surrounding components due to excessively large mounting plates or tightly connected structures. During vehicle operation, the light-emitting components inside the headlights generate heat, causing thermal expansion of components such as the mounting plates of the lens assembly 100. The spaced arrangement of the first mounting plates 33 and the spaced relationship between the reinforcing plate 35 and another mounting plate provide buffer space for thermal deformation of components. When the mounting plates expand due to heat, excessive stress is not generated due to mutual compression, preventing warping or deformation of the mounting plates, thus protecting the positional accuracy and optical performance of the lens body 3. The spaced structure allows the mounting plates to expand freely within a certain range, maintaining the stable working state of the lens assembly 100 and extending its service life.

[0055] According to some embodiments of this application, a lens assembly 100 for a vehicle has a base 1 on which a rotating column 14 is formed. The rotating column 14 is disposed in the middle section of the base 1 and is disposed on at least a portion of the outer periphery of the base 1 and extends in a direction away from the base 1. The rotating column 14 is adapted to cooperate with the vehicle body.

[0056] The rotating column 14 is located in the middle of the base 1 and extends away from the base 1, giving the lens assembly 100 rotational freedom during installation. When used with the vehicle body, the rotating column 14 can be rotated at the corresponding mounting position on the vehicle body to achieve different angles for the lens assembly 100. Since the reserved installation space and angle requirements of the vehicle's front light compartment vary, the rotation of the rotating column 14 allows the lens assembly 100 to easily adapt to different installation angles, such as horizontal, tilted, or vertical, improving the versatility and applicability of the assembly. Furthermore, in actual use, the optical axis angle of the lens body 3 may change due to variations in vehicle load. Factors such as road bumps can cause deviations, affecting the lighting effect. The cooperation between the rotating column 14 and the vehicle body provides a convenient way to adjust the angle of the lens assembly 100. During subsequent maintenance, the optical axis angle of the lens body 3 can be finely adjusted through the rotating column 14 on the rotating base 1 and the gap 5. When the vehicle lighting pattern is found to be deviated, it is not necessary to disassemble the entire lens assembly 100. Simply rotate the rotating column 14 or loosen the fastener 4 to adjust the position of the lens body 3, thereby adjusting the angle of the lens body 3 and restoring the light pattern to normal. This improves the efficiency of angle adjustment and reduces the difficulty and cost of maintenance.

[0057] The vehicle according to an embodiment of this application is briefly described below.

[0058] The vehicle according to the embodiments of this application includes the lens assembly 100 of any of the above embodiments. Since the vehicle according to this embodiment is equipped with the lens assembly 100 of any of the above embodiments, the vehicle according to this application has a lens assembly 100 that can be finely adjusted. The position adjustment of the lens body 3 is flexible, and due to the gap 5 between the fastener 4 and the first mounting hole 31, the position adjustment structure occupies little space and does not increase the cost or outline size of the headlight. When driving in foggy weather, the front fog light of the vehicle using this lens assembly 100 has a more uniform and continuous illumination pattern, and the light no longer has obvious brightness and darkness. Instead of a dividing line, it forms a smooth transition light field between the near-ground and far-field areas, effectively improving light utilization and significantly improving the vehicle's lighting performance in adverse weather conditions. The elimination of light pattern layering greatly reduces visual interference caused by light pattern layering. The uniform lighting pattern allows for clearer and more accurate observation of the road ahead, obstacles, and other vehicles, avoiding visual fatigue and misjudgment caused by sudden changes in light. The adjustability of the lens assembly 100 can also adapt to the influence of different fog concentrations, vehicle loads, and other factors on the headlight pitch angle, always maintaining the best lighting condition and further enhancing vehicle driving safety.
