[0002] Vehicle headlights, also known as front headlights, are mounted on both sides of the front of a car and are used for illuminating the road at night. Because the illumination effect of headlights directly affects nighttime driving and traffic safety, traffic management departments in many countries have stipulated lighting standards in the form of laws. With technological advancements and market demands, increasingly higher requirements are being placed on the illumination accuracy of vehicle headlights.

[0003] The optical components involved in vehicle headlight lighting systems typically include a circuit board with a light source, a light guide, and a lens. The positioning accuracy between these optical components directly affects the accuracy of the lighting system's optical structure, thus impacting its lighting performance. In existing technologies, the positioning and installation of these optical components mostly involve indirectly determining the relative positions of the light guide and lens by fixing the light guide and lens holder to the radiator respectively. Furthermore, the circuit board is fixed to the radiator by screws that pass sequentially through the lens holder and the circuit board. This positioning and installation method is not only structurally complex and cumbersome, but also prone to multiple positioning and installation errors, failing to achieve precise positioning between the light guide and the lens, thereby affecting the accuracy and functional stability of the headlight beam.

[0060] The specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are for illustration and explanation only and are not intended to limit the present invention.

[0061] First, it should be noted that some directional terms used in the following description to clearly illustrate the technical solution of the present invention, such as "up," "down," "left," "right," "front," and "rear," are all derived from the normal orientation of the vehicle when the headlight optical element assembly is applied to it. For example, the front of the vehicle is "front," the rear is "rear," and according to Chinese driving habits, the driver's seat is "left," the passenger seat is "right," the roof is "up," and the wheels are "down," that is... Figure 9 The indicated direction. "Light emission direction" refers to the direction in which the light emitted by the headlight optical element assembly illuminates the vehicle. It can be set according to the desired lighting function of the headlights. For example, the light emission direction of the high and low beam headlights points towards the front of the vehicle, while the light emission direction of the cornering lights is tilted towards the outside of the vehicle.

[0062] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the stated features.

[0063] In the description of this invention, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation" and "connection" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a direct connection or an indirect connection through an intermediate connector; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this invention according to the specific circumstances.

[0064] like Figures 1-8 As shown, the automotive lamp optical element assembly of the present invention includes a light guide component 1 and a lens 2, as well as a support frame 3 for mounting the light guide component 1 and the lens 2. The support frame 3 extends from front to back, and the lens 2 is mounted on the front end of the support frame 3. Figures 1-2As shown, at least one first support portion is provided on each of the two sides (i.e., the left and right sides, the same below) of the light guide component 1, such as... Figure 5 - Figure 6 As shown, the support frame 3 has slots 31 on both sides to accommodate the first support portion. The first support portion and the slots 31 are connected by a first fastener 71 to secure the light guide component 1 within the support frame 3. The slots 31 accommodate the first support portion, and the first fastener 71, such as a bolt or screw, is used to install the light guide component 1 within the support frame 3. Specifically, the first support portion has a support portion mounting hole 711, and correspondingly, the slots 31 have mounting holes and screw posts 712. The first fastener 71 passes through the mounting holes on the support frame 3 and the support portion mounting holes 711 on the first support portion in sequence, and then is threadedly connected to the screw post 712 to install the light guide component 1 within the support frame 3. The first support portion is preferably located on both sides of the front end of the light guide component 1, so that the front end of the light guide component 1 is supported within the support frame 3, preventing the light guide component 1 from vibrating due to the lack of support at its front end during vehicle operation, thus affecting the lighting effect. The first support portion can be as follows: Figures 1-3 The plate-like structure shown can also be a hook-like structure extending forward from the rear of both sides of the light guide component 1. When the first support part is a plate-like structure, the inner and rear sides of the corresponding slot 31 on the support frame 3 are open, and the outer side is closed; when the first support part is a hook-like structure, the rear side of the corresponding slot 31 on the support frame 3 is open, and both the inner and outer sides are closed.

[0065] To improve the installation accuracy of the light guide component 1 and the support frame 3, the light guide component 1 is provided with one of a light guide component positioning hole 15 and a light guide component positioning pin, and the support frame 3 is provided with one of a corresponding support frame positioning pin 37 and a support frame positioning hole, for the vertical, horizontal, and vertical positioning of the light guide component 1 and the support frame 3. Furthermore, the light guide component 1 may also be provided with a positioning protrusion or a positioning groove, and the support frame 3 may be provided with a corresponding positioning groove or positioning protrusion. Figure 7 As shown, the light guide component positioning hole 15 is located at the rear end of the light guide component 1, and the support frame positioning pin 37 is located at the rear end of the support frame 3. Preferably, there are two light guide component positioning holes 15, which are located at opposite ends of the rear end of the light guide component 1. There are also two support frame positioning pins 3, which are located at opposite ends of the rear end of the support frame 3.

[0066] To improve the installation accuracy of lens 2 relative to support frame 3, a lens positioning part is formed on lens 2, and a support frame positioning part is provided on support frame 3 to cooperate with the lens positioning part. Specifically, an outward flange folded towards the outside of lens 2 is formed in the circumferential direction of lens 2. The lens positioning part is one of a positioning groove 21 and a positioning protrusion formed on the outward flange of lens 2, and the support frame positioning part can be one of a positioning protrusion 34 and a positioning groove provided on support frame 3. During installation, the lens positioning part of lens 2 is first engaged with the support frame positioning part on support frame 3, and then fastened, for example, by laser welding.

[0067] To facilitate the installation of lens 2, the vehicle headlight optical component assembly also includes a lens holder 4 that can engage with the support frame 3, with lens 2 clamped between the support frame 3 and the lens holder 4. Specifically, the outer wall of the support frame 3 is provided with one of a buckle 33 and a latch, and the lens holder 4 is provided with the other of a latch 41 and a buckle. Lens 2 has an outwardly folded flange folded towards the outside of lens 2 in its circumferential direction; correspondingly, the lens holder 4 has an inwardly folded flange folded towards the inside of lens holder 4, such as... Figure 8 As shown, after the latch 41 on the lens holder 4 and the buckle 33 on the support frame 3 are engaged, the inner flange of the lens holder 4 can abut against the outer flange of the lens 2, so that the outer flange of the lens 2 is fixed between the support frame 3 and the lens holder 4, thereby realizing the fixed installation of the lens 2.

[0068] In the above technical solution, the first support part of the light guide component 1 is first inserted into the slot 31 of the support frame 3, and then the light guide component 1 is fixedly installed in the support frame 3 using the first fastener 71, etc.; finally, the lens fixing bracket 4 is engaged with the support frame 3 to fix the lens 2 at the front end of the support frame 3.

[0069] Based on the above scheme, the lens mounting bracket 4 is provided with a hook 42, and the support bracket 3 is provided with a support bracket slot 35 that can engage with the hook 42. The hook 42 extends out of the lens mounting bracket 4, and the support bracket slot 35 is located in the middle or rear of the support bracket 3. In this way, the snap-fit ​​structure is forward and the hook-fit structure is rearward. The cooperation between the two makes the lens 2 have higher installation stability.

[0070] Typical vehicle headlights include low-beam optical elements for forming the low beam pattern and high-beam optical elements for forming the high beam pattern. Therefore, the light guide component of this invention may include a low-beam light guide component 11 and a high-beam light guide component 12, such as... Figure 17As shown, the low beam light guide component 11 and the high beam light guide component 12 are arranged vertically, with their front ends in contact and the remaining positions not in contact to prevent light leakage between them; the first support part includes a low beam first support part 111 disposed on the low beam light guide component 11 and a high beam first support part 121 disposed on the high beam light guide component 12, and the low beam first support part 111 and the high beam first support part 121 are positioned by a positioning member 13. Specifically, one of the low beam first support part 111 and the high beam first support part 121 has a positioning hole, and the positioning member 13 is a positioning pin provided on the other and adapted to the positioning hole. The positioning member 13 may be exposed in the high beam first support part 121 or the low beam first support part 111, or it may not be exposed in the low beam first support part 111 or the high beam first support part 121. When it is exposed in the high beam first support part 121 or the low beam first support part 111, a strip groove 32 for the positioning member 13 to pass through is provided in the slot 31 to prevent the positioning member 13 from interfering with the support frame 3 during the process of the light guide component 1 being inserted into the slot 31 from back to front, so that the low beam light guide component 11 and the high beam light guide component 12 can be smoothly installed into the support frame 3.

[0071] A second aspect of the present invention provides a vehicle lighting module, such as... Figures 9-18 As shown, the vehicle lighting module includes a radiator 5, a circuit board 6, and the aforementioned automotive lamp optical component assembly arranged sequentially along the light emission direction. To improve heat dissipation, a fan 8 can be installed behind the radiator 5 to quickly dissipate heat.

[0072] Specifically, the support frame 3 is provided with a support frame mounting hole 36, and the radiator 5 is provided with a radiator mounting hole 51. The support frame mounting hole 36 and the radiator mounting hole 51 are connected by a second fastener 72, such as a bolt or screw, so that the automotive lamp optical component assembly is fixedly mounted on the radiator 5, and the circuit board 6 is clamped between the radiator 5 and the support frame 3. After the automotive lamp optical component assembly is fixedly mounted on the radiator 5, the circuit board 6 is also fixed. There is no need to make holes for screws to pass through in the circuit board 6; the circuit board 6 only needs to be positioned with the light guide component 1.

[0073] If the mounting surfaces of the heat sink 5 and the support bracket 3 are in contact, and the circuit board 6 is thinner than ideal due to manufacturing tolerances, then the circuit board 6 cannot be clamped securely, its position will be uncertain, and it will move back and forth. This cannot guarantee the precise positioning of the light source and other optical components, affecting the accuracy of the optical system. Therefore, to eliminate tolerances, such as Figure 11 As shown, there is a gap between the support frame 3 and the heat sink 5. The support frame 3 is provided with an elastic mounting part 38, which is an elastic arc-shaped deformable component. The support frame mounting hole 36 is provided on the elastic mounting part 38.

[0074] To achieve the positioning of the light guide component 1 and the circuit board 6, the light guide component 1 is provided with a positioning pin 14, the circuit board 6 is provided with a circuit board positioning hole 61 corresponding to the positioning pin 14, and the heat sink 5 is provided with a receiving hole 52 corresponding to the positioning pin 14. There are two circuit board positioning holes 61. To prevent over-positioning, one of the circuit board positioning holes 61 is a round hole and the other is an oblong hole. The receiving hole 52 does not contact the positioning pin 14. In addition, when the support frame positioning component is the support frame positioning pin 37, it does not contact the corresponding through hole on the circuit board 6 or the through hole on the heat sink 5. That is, the heat sink 5 can be fastened to other components without positioning. The support frame 3, the light guide component 1, and the circuit board 6 with the lens 2 installed are positioned to ensure the positioning accuracy between optical components.

[0075] To ensure the front-to-back positioning accuracy of the light guide component 1 and the circuit board 6, the light guide component 1 has a protrusion formed around the positioning hole 15 of the light guide component. The rear end face of the protrusion is formed as a positioning surface 151 that can fit with the circuit board 6. The area of ​​the positioning surface 151 is smaller than the surface area of ​​the light guide component 1 where the protrusion is located. This is because the flatness of a small positioning surface is easier to ensure during processing, resulting in better contact between the light guide component 1 and the circuit board 6 and higher positioning accuracy. If the entire surface of the light guide component 1 where the protrusion is located is in contact with the surface of the circuit board 6, the flatness of the large flat surface needs to be ensured, which is more difficult to process.

[0076] To achieve front-to-back positioning of the light guide component 1, the positioning surface 151 is attached to the circuit board 6, and the opposing surface 152 of the positioning surface 151 on the light guide component 1 is attached to the support frame 3, so that the corresponding part of the light guide component 1 is clamped between the circuit board 6 and the support frame 3, thereby achieving front-to-back positioning of the light guide component 1 and preventing deformation. In addition to the above solution, the first support portion is attached to the inner front surface of the slot 31, and the positioning surface 151 of the light guide component 1 is in contact with the surface of the circuit board 6, which can also achieve front-to-back positioning of the light guide component 1.

[0077] The circuit board 6 includes a low beam circuit board 601 and a high beam circuit board 602. The light guide component 1 includes a low beam light guide component 11 and a high beam light guide component 12. At least one low beam first support portion 111 is provided on both sides of the front end of the low beam light guide component 11. At least one high beam first support portion 121 is provided on both sides of the front end of the high beam light guide component 12. A pair of corresponding low beam first support portions 111 and high beam first support portions 121 are attached to each other and positioned by a positioning member 13.

[0078] Furthermore, at least one low-beam second support portion 112 is provided on each of the rear ends of the low-beam light guide component 11, and at least one high-beam second support portion 122 is provided on each of the rear ends of the high-beam light guide component 12, such as... Figure 17 As shown, since the low beam light guide component 11 and the high beam light guide component 12 only have contact at their front ends, in order to improve the installation stability of the two, the corresponding low beam second support part 112 and the high beam second support part 122 are fitted together to ensure the stability of their relative positions.

[0079] A third aspect of the present invention provides a vehicle lamp that includes the vehicle lighting module described above.

[0080] A fourth aspect of the present invention provides a vehicle including the aforementioned vehicle lights.

[0081] As can be seen from the above description, the present invention has the following advantages: The lens 2 and the light guide component 1 are respectively mounted on the support frame 3. Both the lens 2 and the light guide component 1 have positioning mechanisms relative to the support frame 3, enabling precise positioning of the light guide component 1 and the lens 2. Furthermore, they can be installed as a whole onto the heat sink 5. The installation steps are simple, avoiding installation errors caused by multiple positioning installations in the prior art, thus ensuring the accuracy and functional stability of the vehicle light pattern. In the preferred embodiment of the present invention, the lens 2 is clamped between the lens fixing frame 4 and the support frame 3, with at least two different engagement positions. This not only results in a simple structure and convenient installation but also good installation stability. The circuit board 6 of the vehicle lighting module is clamped... The circuit board 6 is fixed between the heat sink 5 and the support frame 3 in a way that eliminates the need for holes in the circuit board 6 for screws to pass through, making installation convenient and quick. In a preferred embodiment of the invention, to eliminate tolerances and ensure the accuracy of the optical system, there is a gap between the heat sink 5 and the support frame 3, and an elastic mounting part 38 is provided on the support frame 3. Through the elastic action of the elastic mounting part 38, the circuit board 6 can be clamped even if there is a gap, ensuring the precise positioning of the light source and other optical components, and the stable installation of the support frame 3 and the heat sink 5. The mating surfaces on the circuit board 6 and the support frame 3 that are in contact with the light guide component 1 limit the front and rear movement of the light guide component 1. The corresponding part of the light guide component 1 is clamped between the circuit board 6 and the support frame 3, preventing the light guide component 1 from deforming, thereby ensuring the accuracy of the optical system.

[0082] The following is a preferred embodiment of the present invention.

[0083] like Figures 1-8 As shown, the automotive lighting optical element assembly of the present invention includes a low beam guide component 11, a high beam guide component 12, a lens 2, a support frame 3 for mounting the low beam guide component 11, the high beam guide component 12, and the lens 2, and a lens mounting bracket 4 for mounting the lens 2 on the support frame 3. The support frame 3 extends through the entire structure, as shown in the figure. Figures 1-2 As shown, a low beam light guide component 11 has a low beam first support portion 111 on each side of its front end, and a high beam light guide component 12 has a high beam first support portion 121 on each side of its front end, as shown. Figures 5-6 As shown, the support frame 3 has slots 31 on both sides to accommodate the low beam first support 111 and the high beam first support 121. The low beam first support 111 and the high beam first support 121 are positioned by a positioning member 13. The slots 31 have strip-shaped grooves 32 through which the positioning member 13 passes. The low beam first support 111 and the high beam first support 121 are respectively provided with corresponding support mounting holes 71. The slots 31 are provided with screw posts 712 that are threaded to screws. The low beam first support 111 and the high beam first support 121 are fastened to the support frame 3 by screws. The low beam first support 111 and the high beam first support 121 are as follows: Figures 1-3 The plate-like structure shown has openings on the inner and rear sides of the corresponding slots 31 on the support frame 3, while the outer side is closed. The rear end of the low beam guide component 11 and the rear end of the high beam guide component 12 each have a light guide component positioning hole 15, located diagonally opposite each other.
