Description

Technical Field

[0001] This application relates to the field of automotive lighting technology, and in particular to a low beam lens module. Background Technology

[0002] Currently, low beam lens assemblies mainly employ two schemes: the Poly-Ellipsoid System (PES) and the direct-projection scheme. The PES scheme primarily consists of a reflector, a low beam baffle, and a projection lens, while the direct-projection scheme mainly consists of an inner lens, a low beam baffle, and a projection lens. The main difference between the two schemes lies in how they focus the light from the light-emitting diode (LED). The direct-projection scheme offers advantages such as lighter weight. However, the current installation process for low beam lens assemblies is cumbersome, hindering automated installation and resulting in low assembly efficiency. Utility Model Content

[0003] This application provides a low beam lens module that simplifies the installation steps and improves assembly efficiency, thereby at least partially solving the aforementioned technical problems.

[0004] To achieve the above objectives, according to a first aspect of this application, a low beam lens module is provided, the low beam lens module having a first orientation, including:

[0005] Lens support assembly, including an integrated lens support and a light pattern baffle;

[0008] The light-emitting component is disposed on the side of the inner lens away from the light pattern baffle in the first direction. The light emitted by the light-emitting component can pass through the inner lens and the light pattern baffle in sequence and be emitted from the outer lens.

[0009] Optionally, the lens bracket includes a mounting plate, a positioning plate, and a limiting plate, wherein the mounting plate and the positioning plate are connected, and the limiting plates are located on both sides of the positioning plate;

[0010] The lens support assembly also includes a top cover, which is detachably connected to the lens support. The top cover, the limiting plate, the mounting plate, and the positioning plate enclose a mounting cavity, and a light pattern baffle is set inside the mounting cavity.

[0011] Optionally, snap-fit ​​pieces are provided on both sides of the top cover, and snap-fit ​​grooves are provided on the limiting plate, with the snap-fit ​​pieces and snap-fit ​​grooves engaging.

[0012] Optionally, the low beam lens module also includes an ellipsoid, which is disposed on the lens bracket and is located between the outer lens and the beam pattern baffle in the first direction. A plurality of second positioning posts are provided on the side of the ellipsoid facing the positioning plate, and a plurality of second positioning slots are provided on the positioning plate. The second positioning posts and the second positioning slots are inserted into each other.

[0013] Optionally, a guide post is provided on the side of the ellipsoid facing the limiting plate, and a first guide piece and a second guide piece are provided on the limiting plate. The first guide piece and the second guide piece are disposed in the mounting cavity, and a guide groove is formed between the first guide piece and the second guide piece. The guide post is slidably inserted into the guide groove.

[0014] Optionally, the inner lens has a pre-installed hole, and the mounting plate has a pre-installed post on the side facing the inner lens, with the pre-installed post and the pre-installed hole being inserted into each other.

[0015] Optionally, the outer lens has an incident light surface and an exit light surface arranged opposite to each other. A plurality of first positioning posts are provided on one side of the incident light surface of the outer lens, and a plurality of first positioning slots are provided on the lens bracket. Each first positioning post is provided in correspondence with each first positioning slot, and the first positioning post and the first positioning slot are inserted into each other.

[0016] Optionally, it also includes a radiator, which is mounted on the mounting plate.

[0017] Optionally, the light-emitting component includes a circuit board and multiple light-emitting elements integrated on the circuit board. The light-emitting component is disposed between the heat sink and the inner lens.

[0018] Optionally, the inner lens includes an inner lens body and an inner lens support, wherein the inner lens body and the inner lens support are separate assembly structures.

[0019] This application achieves the following technical effects: The lens bracket assembly of the low beam lens module includes an integrated lens bracket and a beam pattern baffle, meaning the beam pattern baffle is integrated into the lens bracket. This eliminates the assembly steps of separately positioning and fixing the beam pattern baffle in traditional split structures, significantly reducing manual operation steps, assembly time, and labor costs. Simultaneously, it avoids positioning deviations caused by manual operation, controlling assembly errors from the source, improving the relative positional accuracy of parts, and ensuring a stable and consistent optical fit between the inner lens, beam pattern baffle, and outer lens, laying a structural foundation for precise control of the light propagation path. This application facilitates automated installation, improves assembly efficiency, and is compatible with the smooth operation of automated production lines. Modular installation can be directly completed by a robotic arm, improving assembly efficiency and reducing the difficulty of automation transformation, making it particularly suitable for large-scale mass production scenarios. The integrated molding structure offers higher strength than split-type connections, reducing the impact of external factors such as vibration and temperature changes on the beam pattern baffle's position. This prevents beam pattern shifts caused by component loosening, allowing the baffle to precisely block stray light. Combined with the inner and outer lenses' focusing and refraction of light, this achieves a more regular low-beam output, improving illumination uniformity and effective range, and reducing glare interference for other road users. Furthermore, reducing connecting components lowers the risk of component failure, enhances the overall reliability of the low-beam lens module, extends its service life, and combines advantages in manufacturing economy and optical performance.

Detailed Implementation

[0034] 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 protection scope of this application.

[0035] There are two main structural designs for direct-projection systems. One design uses an inner lens, a low-beam baffle, a projection lens, and a lens support. In this design, the low-beam baffle and the lens support are not integrally connected and need to be assembled during the assembly process. Furthermore, the low-beam baffle in this design is primarily a stamped metal baffle, and its deformation can negatively impact the optical performance of the low-beam system. The other design combines the inner lens, low-beam baffle, and projection lens into a single thick-walled lens to achieve the low-beam function. However, this thick-walled lens design is limited by the higher injection molding and mold costs associated with thick-walled optical lenses, failing to effectively reduce costs. In fact, the multiple defects inherent in thick-walled injection molding increase the system's defect rate and reduce production consistency.

[0036] In view of this, this application provides a low beam lens module, please refer to... Figure 1 and Figure 2 , Figure 1 This is a schematic diagram of the low beam lens module provided in an embodiment of this application.

[0037] Reference Figure 1 and Figure 2 The low beam lens module has a first direction X. The low beam lens module includes a lens support assembly 1, an outer lens 20, an inner lens 40, and a light-emitting component 60. The lens support assembly 1 includes an integral lens support 10 and a light pattern baffle 11. The outer lens 20 is disposed on the lens support 10 and is located on one side of the light pattern baffle 11 in the first direction X. The inner lens 40 is disposed on the lens support 10 and is located on the other side of the light pattern baffle 11 in the first direction X. The light-emitting component 60 is disposed on the side of the inner lens 40 away from the light pattern baffle 11 in the first direction X. The light emitted by the light-emitting component 60 can pass through the inner lens 40 and the light pattern baffle 11 in sequence and be emitted from the outer lens 20.

[0038] The lens support assembly 1 provided in this application embodiment includes an integral lens support 10 and a beam pattern baffle 11. That is, the beam pattern baffle 11 is integrally integrated into the lens support 10, saving the assembly step of installing the beam pattern baffle 11 onto the lens support 10, simplifying the installation steps of the low beam lens module, reducing assembly errors, and improving the optical performance of the low beam lens module. Furthermore, the beam pattern baffle 11 is located between the inner lens 40 and the outer lens 20, effectively constraining the light path, reducing stray light interference, and improving beam pattern uniformity.

[0039] Reference Figure 2 and Figure 3In some embodiments, the lens holder 10 includes a mounting plate 12, a positioning plate 13, and a limiting plate 14. The mounting plate 12 and the positioning plate 13 are connected, and the limiting plate 14 is located on both sides of the positioning plate 13. The lens holder assembly 1 also includes a top cover 50, which is detachably connected to the lens holder 10. The top cover 50, the limiting plate 14, the mounting plate 12, and the positioning plate 13 enclose a mounting cavity 15, and a light pattern baffle 11 is disposed within the mounting cavity 15. The light pattern baffle 11 is fixed within the mounting cavity 15, which enhances the positioning accuracy and deformation resistance of the light pattern baffle 11. The detachable top cover 50 design facilitates the installation and maintenance of the light pattern baffle 11, while reducing the impact of external contamination on the optical components.

[0040] Specifically, the lens holder 10 can be made of plastic. Using plastic for the lens holder 10 results in higher molding precision and is more conducive to optical performance.

[0041] Specifically, the outer lens 20 can be made of poly(methylmethacrylate) (PMMA). PMMA has advantages such as high transparency, low cost, easy machining, and light weight.

[0042] Specifically, the upper cover 50 has snap-fit ​​pieces 51 on both sides, and the limiting plate 14 has snap-fit ​​grooves 141. The snap-fit ​​pieces 51 and snap-fit ​​grooves 141 are inserted into each other. Through the insertion and engagement of the snap-fit ​​pieces 51 and snap-fit ​​grooves 141, the upper cover 50 and the limiting plate 14 are quickly locked together, simplifying the assembly steps and improving assembly efficiency. The snap-fit ​​structure can also avoid the stress concentration problem caused by traditional screw fixing, thus improving the overall structural reliability.

[0043] Specifically, the inner lens 40 has a near-light condenser on the side closest to the light-emitting component 60, and a stepped rectangular optical surface with a height difference on the side closest to the outer lens 20. The near-light condenser is used to form parallel light, thereby working with the beam pattern baffle 11 and the outer lens 20 to form the desired beam pattern. The stepped rectangular optical surface is used to converge the parallel light rays, working with the beam pattern baffle 11 and the outer lens 20 to achieve the beam pattern and energy distribution of the near light.

[0044] In some examples, refer to Figure 2 , Figure 3 and Figure 6 The low beam lens module also includes an ellipsoid 30, which is disposed on the lens bracket 10 and is located between the outer lens 20 and the light pattern baffle 11 in the first direction X. Multiple second positioning posts 31 are provided on the side of the ellipsoid 30 facing the positioning plate 13. Multiple second positioning grooves 131 are provided on the positioning plate 13, and the second positioning posts 31 and the second positioning grooves 131 are inserted and engaged.

[0045] By connecting the ellipsoid 30 to the lens bracket 10, the precise position of the ellipsoid 30 in the optical path is ensured, optimizing the light focusing effect. The introduction of the ellipsoid 30 can further correct the light pattern, reduce optical distortion, and improve the illumination uniformity and cutoff line clarity of the low beam system.

[0046] Specifically, the material of ellipsoid 30 can be polycarbonate (PC), which has advantages such as high strength, impact resistance, and high transparency.

[0047] Furthermore, a guide post 32 is provided on the side of the ellipsoid 30 facing the limiting plate 14. The limiting plate 14 is provided with a first guide plate 142 and a second guide plate 143. The first guide plate 142 and the second guide plate 143 are disposed in the mounting cavity 15, and a guide groove 144 is formed between the first guide plate 142 and the second guide plate 143. The guide post 32 is slidably inserted into the guide groove 144. The sliding fit design between the guide post 32 and the guide groove 144 enables the ellipsoid 30 to automatically align during installation, reducing manual adjustment errors. The limiting function of the guide groove 144 can prevent the ellipsoid 30 from shifting, ensuring the stability of the optical path, while improving assembly efficiency and consistency.

[0048] Furthermore, the ellipsoid 30 has a microstructure on the side near the outer lens 20. The microstructure is fish-scale shaped and distributed on the surface of the outer lens 20. The microstructure continuously refracts and controls the light, making the light propagate more evenly inside the low-light lens module, which helps to improve the uniformity of illumination. The side of the ellipsoid 30 near the outer lens 20 and the side near the light pattern baffle 11 are both designed as convex lenses, which can avoid ablation of the lens decorative frame near the ellipsoid 30.

[0049] Reference Figure 3 and Figure 7 The inner lens 40 provided in this application includes an inner lens body 43 and an inner lens support 44, which are separate assembly structures. The inner lens support 44 of the inner lens 40 has a pre-installation hole 41, and a pre-installation post 123 is provided on the side of the mounting plate 12 facing the inner lens 40. The pre-installation post 123 is inserted into the pre-installation hole 41. The insertion and engagement of the pre-installation post 123 with the pre-installation hole 41 enables rapid pre-positioning of the inner lens 40 and the mounting plate 12, avoiding misalignment during assembly, shortening assembly time, and improving assembly efficiency. Specifically, in this embodiment, two pre-installation holes 41 are provided, one of which is a round hole and the other is an oblong hole. The round hole is used for the main positioning of the inner lens 40, and the oblong hole is used to control the positioning accuracy while preventing over-positioning.

[0050] Reference Figure 3 and Figure 5The outer lens 20 has an incident light surface 21 and an exit light surface 22 arranged opposite to each other. Multiple first positioning posts 23 are provided on one side of the incident light surface 21 of the outer lens 20. Multiple first positioning slots 16 are provided on the lens support 10. Each first positioning post 23 corresponds to each first positioning slot 16, and the first positioning posts 23 and first positioning slots 16 are interlocked. The outer lens 20 precisely aligns with the first positioning posts 23 and the first positioning slots 16 on the lens support 10, ensuring that the relative positions of the incident light surface 21 and the exit light surface 22 meet design requirements and reducing light loss. The interlocking structure also buffers vibration and impact, improving the vibration resistance of the outer lens 20. The outer lens 20 is used to project and expand the light output from the light-emitting component 60 to achieve the illumination area and angle required for the near-beam function.

[0051] Reference Figure 2 and Figure 9 In some examples, the low beam lens module also includes a heat sink 70, which is manufactured using a cold forging process and is mounted on the mounting plate 12. By directly mounting the heat sink 70 to the mounting plate 12, the heat generated by the light-emitting component 60 can be quickly conducted to the outside, avoiding light decay or component damage caused by high temperature and extending the module's service life; at the same time, it simplifies the heat dissipation path and improves heat dissipation efficiency.

[0052] Reference Figures 2 to 9 The light-emitting component 60 includes a circuit board 61 and multiple light-emitting elements 62 integrated on the circuit board 61. The integrated design of the multiple light-emitting elements 62 improves the light output intensity. The light-emitting component 60 is disposed between the heat sink 70 and the inner lens 40. A first positioning hole 63 is provided on the circuit board 61, and a pre-installation post 123 is provided on the lens bracket 10. The pre-installation post 123 passes through the first positioning hole 63 and is inserted into the first positioning hole 63 to realize the pre-installation of the circuit board 61 and ensure the precise alignment of the light-emitting component 60 and the lens bracket 10. Specifically, in this embodiment, there are two first positioning holes 63, one of which is a round hole and the other is an oblong hole. The round hole is used to realize the main positioning of the circuit board 61, and the oblong hole is used to control the positioning accuracy and prevent over-positioning. A clearance post 71 is provided on the heat sink 70, which creates a gap between the heat sink 70 and the circuit board 61. The gap between the circuit board 61 and the heat sink 70 is coated with thermally conductive adhesive, thereby helping to enhance the heat conduction efficiency.

[0053] Furthermore, the circuit board 61 can be made of aluminum, which can achieve better heat conduction and heat dissipation.

[0054] The mounting plate 12 has a first fixing hole 121, the circuit board 61 has a second fixing hole 64, the inner lens 40 has a third fixing hole 42, and the heat sink 70 has a fourth fixing hole 72. The first fixing hole 121, the second fixing hole 64, the third fixing hole 42, and the fourth fixing hole 72 are all arranged opposite each other and are used for inserting fasteners. In this embodiment, the fastener is specifically a pull screw. The fastener enables synchronous tightening of multi-level structures, simplifying the assembly process; the centralized fixing method also improves the overall structural integrity and reduces the risk of optical path misalignment caused by loosening of multiple components.

[0055] Furthermore, referring to Figure 3 The low beam lens module provided in this application also includes a limiting rib 80 and a welding rib 90. The limiting rib 80 is fixed to the side of the positioning plate 13 facing the upper cover 50. The ellipsoid 30 is laser welded to the positioning plate 13. The limiting rib 80 is used to fix the ellipsoid 30 to the positioning plate 13 after laser welding and melting. The welding rib 90 is fixed to the side of the positioning plate 13 facing the outer lens 20. The outer lens 20 is laser welded to the positioning plate 13. The welding rib 90 is used to fix the outer lens 20 to the positioning plate 13 after laser welding and melting.

[0056] The low beam lens module provided in this application first fixes the outer lens 20 and ellipsoid 30 to the lens bracket 10, then fixes the upper cover 50 to the lens bracket 10 by inserting the snap-fit ​​piece 51 into the snap-fit ​​groove 141, pre-installs the inner lens 40 on the lens bracket 10, then places the circuit board 61 on the inner lens 40, and finally fixes the heat sink 70 to the lens bracket 10 by pulling screws. The lens bracket assembly 1 of the low beam lens module provided in this application integrates the light pattern baffle 11 with the lens bracket 10, which significantly simplifies the assembly process, eliminates the assembly steps of separately positioning and fixing the light pattern baffle 11 in the traditional split structure, greatly reduces manual operation steps, reduces assembly time and labor costs, and avoids positioning deviation caused by manual operation. It controls assembly errors from the source, improves the relative position accuracy of parts, and ensures that the optical matching relationship between the inner lens 40, the light pattern baffle 11 and the outer lens 20 is stable and consistent, laying a structural foundation for precise control of the light propagation path.

[0057] This design eliminates the need for component flipping. During assembly, there is no flipping process, which facilitates automated installation, improves assembly efficiency, and is compatible with the smooth operation of automated production lines. Modular installation can be directly completed by a robotic arm, improving assembly efficiency and reducing the difficulty of automation upgrades, making it particularly suitable for large-scale mass production scenarios. The integrated structure has higher strength than split-type connections, reducing the impact of external factors such as vibration and temperature changes on the position of the beam pattern baffle 11. This avoids beam pattern shifts caused by component loosening, allowing the beam pattern baffle 11 to accurately block stray light. Combined with the convergence and refraction of light by the inner and outer lenses, it achieves a regularized output of the low beam pattern, improving illumination uniformity and effective range, and reducing glare interference to other road users. Furthermore, reducing connecting components lowers the risk of component failure, enhances the overall reliability of the low beam lens module, extends its service life, and combines advantages in process economy and optical performance.
