Description

Technical Field

[0001] This utility model relates to the field of automotive lighting technology, and more specifically, to a high / low beam lens module and an automotive lighting system. Background Technology

[0002] In addition to providing illumination for drivers, vehicle lights also need to serve as a warning to pedestrians. The light pattern must provide sufficient brightness without interfering with other drivers on the road. Laws and regulations impose constraints and requirements on the light patterns of vehicle lights. To meet these regulatory requirements, vehicle lights have a more complex structure than ordinary lighting equipment, resulting in a more complex assembly process, higher precision requirements, and increased assembly costs.

[0003] This application aims to improve upon this. Utility Model Content

[0004] This invention overcomes the shortcomings of existing complex vehicle headlight assembly and provides a high and low beam lens module and vehicle headlight. By improving the module structure, it assembles components other than the PCB and reflector bowl in the same direction, reducing assembly complexity and improving assembly efficiency and yield.

[0005] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0006] A high beam and low beam lens module includes a heat sink, a PCB, a reflector, a beam pattern baffle, a lens bracket, a first lens, a decorative element, and a second lens arranged along a first direction. The beam pattern baffle, lens bracket, first lens, second lens, and decorative element are sequentially mounted on the heat sink along the first direction. Along a second direction, the reflector and PCB are sequentially mounted on the heat sink. The first direction and the second direction are perpendicular.

[0007] The structure simplifies the assembly of the low beam module. Except for the reflector bowl and PCB installed along the second direction, the assembly direction is the first direction. For the other structures, the heat sink or decorative parts can be positioned by tooling, and then the corresponding parts can be installed one by one, thereby reducing the assembly difficulty and making it suitable for the installation of robotic arms.

[0008] Preferably, the heat sink has an N-shaped contact surface, including a first contact surface and two second contact surfaces normal to the first direction. The first contact surface is inclined to both the first and second directions. The lens bracket has bracket flanges that adapt to the spatial position of the two second contact surfaces, and the bracket flanges are attached to the two second contact surfaces. The heat sink transfers heat and is fixed through the contact surfaces. The first contact surface is used to position the PCB, and the second contact surfaces are used to position the lens bracket. The lens bracket, through the bracket flanges, attaches the two different planes to the second contact surfaces, which can maintain reliable connection and reduce stress.

[0009] Preferably, the PCB is bonded to the first bonding surface, and the fastener passes through the reflector bowl and the PCB to be fixedly connected to the heat sink, with the axial direction of the fastener being set along the second direction.

[0010] Preferably, the top of the lens holder is provided with a positioning notch, the two ends of the first lens are provided with flanges, and the second lens is mounted on the positioning notch through the flanges.

[0011] Preferably, the light-patterned baffle is fixedly connected to the heat sink by fasteners.

[0012] Preferably, the light pattern baffle includes a heat sink and a light-blocking block. The heat sink is attached to the heat sink, and the light-blocking block has an arc-shaped light-blocking protrusion positioned in the light path generated by the near-light source on the PCB. The light pattern baffle is directly fixed to the heat sink, and heat is dissipated through the heat sink, which can prevent thermal deformation from causing light pattern deviation.

[0013] Preferably, the inner diameter of the decorative element gradually increases along the direction from the decorative element to the radiator. This structure serves as a guide and facilitates connection to the lens holder.

[0014] Preferably, the inner side of the decorative part is provided with a positioning rib that adapts to the positioning notch, and the positioning rib presses the flange onto the positioning notch. The positioning rib cooperates with the positioning notch to position the flange, thereby positioning the first lens.

[0015] Preferably, the decorative element has a positioning flange at its top, and the second lens has an annular positioning ring at its top that adapts to the positioning flange. The positioning flange fits snugly against the annular positioning ring. Positioning grooves are provided at each corner of the bottom of the second lens, and a support protrusion is provided at the bottom of the lens holder, which is inserted into the positioning groove. The positioning flange, annular positioning ring, positioning groove, and positioning protrusion of the decorative element achieve the positioning of the second lens.

[0031] Example:

[0032] A high and low beam lens module, reference Figure 1 As shown, the structure includes a heat sink 1, a PCB 2, a reflector bowl 3, a beam pattern baffle 4, a lens bracket 5, a first lens 6, a decorative element 7, and a second lens 8, all arranged along a first direction. The heat sink 1 dissipates heat from the PCB 2, which contains a high beam source, a low beam source, and peripheral circuitry for controlling them. During illumination, the high beam and low beam sources generate significant heat, which the heat sink 1 dissipates by adhering to the PCB 2. The reflector bowl 3 is fixedly connected to the PCB 2, reflecting the emitted light to correct its direction and direct it towards the lens. The beam pattern baffle 4 is located along the light path and blocks part of the light, creating a clear cutoff line to meet regulatory requirements. The lens bracket 5 and the decorative element 7 position the first lens 6 and the second lens 8. The low beam path passes through both the first lens 6 and the second lens 8, while the high beam path passes through the second lens 8. The reuse of the second lens 8 simplifies the structure.

[0033] The heat sink 1 has an N-shaped contact surface, including a first contact surface 9 and two second contact surfaces 10 normal to the first direction. The first contact surface 9 is inclined to both the first and second directions. The lens bracket 5 has bracket flanges 11 that adapt to the spatial position of the two second contact surfaces 10, and the bracket flanges 11 are attached to the two second contact surfaces 10. The heat sink 1 transfers heat and is fixed through the contact surfaces. The first contact surface 9 is used to position the PCB 2, and the second contact surfaces 10 are used to position the lens bracket 5. The lens bracket 5, through the bracket flanges 11, attaches two different planes to the second contact surfaces 10, which can maintain reliable connection and reduce stress. On the back side of the contact surfaces, the heat sink 1 has several fins, which increase the contact area with the air, thereby accelerating the heat exchange between the heat sink 1 and the air.

[0034] On this basis, by adjusting the structures and shapes of each component, the light pattern baffle 4, the lens holder 5, the first lens 6, the second lens 8, and the decorative part 7 are sequentially installed on the radiator 1 along the first direction. The light pattern baffle 4 is fixedly connected to the radiator 1 through fasteners. The light pattern baffle 4 is provided with a heat dissipation plate 12 and a light blocking block 13. The heat dissipation block is fitted to the radiator 1, and the light blocking block 13 is provided with an arc-shaped light blocking protrusion, and the light blocking protrusion is arranged on the optical path of the low beam light source on the PCB 2. The light pattern baffle 4 is directly fixedly connected to the radiator 1 and dissipates heat through the heat dissipation plate 12, which can avoid light pattern deviation caused by thermal deformation.

[0035] See Figure 2 As shown, the top of the lens holder 5 is provided with a positioning notch 14, both ends of the first lens 6 are provided with flanges 15, and the second lens 8 is mounted on the positioning notch 14 through the flanges 15. The inner side of the decorative part 7 is provided with positioning ribs 16 adapted to the positioning notch 14, and the positioning ribs 16 press-fit the flanges 15 on the positioning notch 14. The positioning ribs 16 cooperate with the positioning notch 14 to position the flange 15, thereby positioning the first lens 6. Along the direction from the decorative part 7 to the radiator 1, the inner diameter of the decorative part 7 gradually increases. The said structure plays a guiding role and is easy to connect with the lens holder 5. The top of the decorative part 7 is provided with a positioning flange 17, the top of the second lens 8 is provided with an annular positioning ring 18 adapted to the positioning flange 17, the positioning flange 17 is in contact with the annular positioning ring 18, and each corner point at the bottom of the second lens 8 is provided with a positioning groove 19, and the bottom of the lens holder 5 is provided with a bracket convex edge 20, and the bracket convex edge 20 is inserted into the positioning groove 19. The positioning flange 17 - annular positioning ring 18 and the positioning groove 19 - positioning convex edge of the decorative part 7 realize the positioning of the second lens 8.

[0036] Along the second direction perpendicular to the first direction, the reflector bowl 3 and the PCB 2 are sequentially installed on the radiator 1. The PCB 2 is fitted on the first fitting surface 9, and the fasteners pass through the reflector bowl 3 and the PCB 2 and are fixedly connected to the radiator 1, and the axial direction of the fasteners is arranged along the second direction.

[0037] Through the said structure, the assembly of the low beam module is simplified. Except for the reflector bowl 3 and the PCB 2 installed along the second direction, the assembly direction of the first direction is adopted for the rest of the structures. For the remaining structures, the radiator 1 or the decorative part 7 can be positioned through a tooling, and then the corresponding components are installed one by one, thereby reducing the assembly difficulty and being suitable for installation by a robotic arm.

[0038] The assembly method of the above structure includes:

[0039] First, fix the radiator 1, the PCB 2, and the reflector bowl 3 with fasteners; then fix the radiator 1 on the tooling for positioning, and then install the light pattern baffle 4 on the radiator 1 with fasteners. On this basis, pre-position the lens holder 5, and place the first lens 6 on the positioning notch 14 of the lens holder 5; at the same time, pre-position the first lens 6 to the decorative part 7, and install the decorative part 7 on the lens holder 5, and fix the lens holder 5, the decorative part 7, and the radiator 1 with fasteners. In the above installation method, the first direction is the height direction, and each component is placed from top to bottom in this way, with the radiator 1 at the bottom, and pre-positioning is carried out by using gravity.

[0040] As shown Figure 3 in the figure, in another embodiment, the first lens 6 and the lens holder 5 are of an integral structure, the lens holder 5 is snap-connected to the decorative part 7, and the radiator 1 is fixedly connected to the decorative part 7 with fasteners. In this embodiment, the decorative part 7 is inverted and positioned by the tooling, and then the second lens 8 is placed, and the lens holder 5 and the radiator 1 with the PCB 2 and the reflector bowl 3 are successively snap-connected along the axial direction of the decorative part 7. Among them, the radiator can be of a double-layer structure to reduce the processing difficulty, and the double-layer radiator is connected by a fastener method.

[0041] On this basis, this embodiment also claims to protect a vehicle lamp, including the high and low beam lens holder 5 as described above.
