[0033] The technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings.

[0034] In the description of this application, it should be noted that the terms "inner" and "outer," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, or the orientation or positional relationship commonly used when the product is in use. They are used only for the convenience of describing this application and for simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this application. Furthermore, the terms "first," "second," etc., are used only to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0035] It should also be noted that, unless otherwise explicitly specified and limited, the terms "setup" 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 medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0036] Please refer to Figure 1 As shown, this application provides an optical module that can be applied to vehicle lights. It includes a heat dissipation element 40, a bracket 10, and a lens 60 arranged sequentially along a first direction F1. A light source 50 and a primary optical element 20 are arranged sequentially on the heat dissipation element 40 along a second direction F2. One side of the bracket 10 is connected to the lens 60, and the other side of the bracket 10 is engaged with at least one of the heat dissipation element 40, the primary optical element 20, and the heat dissipation element 40. The light source 50 is mounted on the heat dissipation element 40. The light emitted from the light source 50 is converged by the primary optical element 20 and then emitted by the lens 60 to form a light pattern.

[0037] Preferably, the other side of the bracket 10 and the heat dissipation element 40, the primary optical element 20 and the heat dissipation element 40 are all snap-fit ​​connected, so that there is no need to use screws for connection, which makes the installation easy, efficient and low cost.

[0038] The bracket 10 has a hollow structure. One side of the bracket 10 along the first direction F1 is used to fix the lens 60, and the other side of the bracket 10 is used to engage and fix with the heat dissipation element 40.

[0039] A light source 50 and a primary optical element 20 are sequentially arranged on the heat dissipation element 40 along the second direction F2. The light source 50 is fixed on the heat dissipation element 40, and the primary optical element 20 is engaged and fixed with the heat dissipation element 40. The heat dissipation element 40 can effectively dissipate heat from the light source 50 and the primary optical element 20 to ensure the working performance of the module and prevent overheating damage to the components.

[0040] Among them, such as Figure 2 As shown, the optical module also includes a circuit board 30, on which a light source 50 is disposed, and the circuit board 30 is attached to the heat dissipation element 40.

[0041] The light-emitting surface of the light source 50 is positioned facing the primary optical element 20. The light emitted from the light source 50 is first converged by the primary optical element 20 and then directed to the lens 60, and then emitted from the lens 60 and projected to form a light pattern.

[0042] The optical module provided in this application embodiment has a heat dissipation element 40 connected to at least one of the bracket 10 and the primary optical element 20 by a snap-fit ​​connection method, which is different from the screw connection method in the prior art. This makes installation easier, assembly more efficient and less costly. In addition, the optical module has a compact overall structure, small size and light weight, which is also conducive to achieving the miniaturization requirements.

[0043] The primary optical element 20 includes at least one of a reflector 23, a condenser, and an inner lens to converge the diverging light rays emitted from the light source 50, and then reflect or refract the converged light rays to the lens 60 for emission. The condenser can be a transparent optical element in the shape of a condenser cup, and the inner lens is a transparent optical element disposed inside the lens 60 that has a converging effect on light rays; its specific shape is not limited.

[0044] Preferably, the primary optical element 20 includes a reflector 23. The light emitted from the light source 50 is first converged and reflected by the reflector 23 and then directed to the lens 60, and then emitted from the lens 60 and projected to form a light pattern.

[0045] For heat dissipation element 40 and primary optical element 20, please refer to Figure 4 and Figure 5As shown, the primary optical element 20 is provided with a first latch 22, and the heat dissipation element 40 is provided with a corresponding first mounting rib 44. The primary optical element 20 and the heat dissipation element 40 are connected by the cooperation of the first latch 22 and the first mounting rib 44. For example, the primary optical element 20 includes two first latches 22 arranged opposite each other along a third direction F3, and a reflector 23 is provided between the two first latches 22. The heat dissipation element 40 is provided with first mounting ribs 44 corresponding to the position and number of the first latches 22. The primary optical element 20 is clamped on the heat dissipation element 40 by the cooperation of the first latches 22 and the first mounting ribs 44.

[0046] Preferably, in this embodiment, the primary optical element 20 includes a reflector 23 and two first latches 22, with the reflector 23 positioned between the two first latches 22. The reflector 23 is used to reflect the light emitted from the light source 50 to the lens 60. Correspondingly, the heat dissipation element 40 also has two first mounting ribs 44. The first latches 22 extend downward toward the heat dissipation element 40 along the second direction F2 and engage with the first mounting ribs 44 of the heat dissipation element 40. In this way, the primary optical element 20 is clamped onto the heat dissipation element 40 by the two first latches 22, achieving a secure and convenient connection between the primary optical element 20 and the heat dissipation element 40 without the need for screws.

[0047] It should be noted that the accompanying drawings of this embodiment only show the case where the first buckle 22 is provided on the primary optical element 20 and the first mounting rib 44 is provided on the heat dissipation element 40. In fact, the first mounting rib 44 can also be provided on the primary optical element 20 and the first buckle 22 can be provided on the heat dissipation element 40. The primary optical element 20 and the heat dissipation element 40 can be connected by the cooperation of the first buckle 22 and the first mounting rib 44.

[0048] Furthermore, such as Figure 4 and Figure 5 As shown, when the primary optical element 20 and the heat dissipation element 40 are fixed, a pin 21 is also provided on the primary optical element 20, and a corresponding second pin hole 43 is provided on the heat dissipation element 40. The pin 21 passes through the second pin hole 43 to achieve the installation and positioning of the primary optical element 20 and the heat dissipation element 40. Furthermore, as... Figure 6As shown, the circuit board 30 has a first pin hole corresponding to the pin 21 and the second pin hole 43. The pin 21 can pass through the first pin hole and the second pin hole 43 to realize the installation and positioning of the primary optical element 20, the circuit board 30 and the heat dissipation element 40. In order to facilitate the adjustment of the installation position of the primary optical element 20 and the circuit board 30, the first pin hole includes at least one oblong hole 31. For example, the primary optical element 20 includes a reflector 23. Two pins 21 are symmetrically arranged on the primary optical element 20 about the reflector 23 along the third direction F3. Correspondingly, the heat dissipation element 40 has two second pin holes 43, one of which is an oblong hole and the other is a round hole. The circuit board 30 has two first pin holes, one of which is an oblong hole 31 and the other is a round hole 32. Two pins 21, two first pin holes, and two second pin holes 43 correspond one-to-one. The pins 21 are inserted into the first pin holes and the second pin holes 43 to achieve the installation and positioning of the primary optical element 20, the circuit board 30, and the heat dissipation element 40.

[0049] After the primary optical element 20, circuit board 30, and heat dissipation element 40 are installed, the following is obtained: Figure 3 The assembly structure shown.

[0050] On the other hand, regarding the engagement of the heat dissipation element 40 and the bracket 10, the bracket 10 is provided with a second latch 11, and the heat dissipation element 40 is correspondingly provided with a second mounting rib 41. The bracket 10 and the heat dissipation element 40 are engaged and connected through the cooperation of the second latch 11 and the second mounting rib 41. For example, the bracket 10 includes two second latches 11 arranged opposite each other along a third direction F3. The heat dissipation element 40 is provided with second mounting ribs 41 corresponding to the position and number of the second latches 11. Through the cooperation of the second latches 11 and the second mounting ribs 41, the bracket 10 is clamped onto the heat dissipation element 40. In this embodiment, there are two second latches 11, which extend towards the heat dissipation element 40 along a first direction F1 and engage with the second mounting ribs 41 of the heat dissipation element 40. In this way, the bracket 10 is clamped onto the heat dissipation element 40 by the two second latches 11, realizing the engagement connection between the bracket 10 and the heat dissipation element 40. This achieves a secure and convenient installation without the need for screws.

[0051] It should be noted that the accompanying drawings of this embodiment only show the case where the second buckle 11 is provided on the bracket 10 and the second mounting rib 41 is provided on the heat dissipation element 40. In fact, the second mounting rib 41 can also be provided on the bracket 10 and the second buckle 11 can be provided on the heat dissipation element 40. The bracket 10 and the heat dissipation element 40 can be connected by the cooperation of the second buckle 11 and the second mounting rib 41.

[0052] Furthermore, such as Figure 5 and Figure 7As shown, when the bracket 10 is fixed to the heat dissipation element 40, a positioning hole 12 is also provided on the bracket 10, and a positioning pin 42 is correspondingly provided on the heat dissipation element 40. The positioning pin 42 passes through the positioning hole 12 to realize the installation and positioning of the bracket 10 and the heat dissipation element 40.

[0053] The positioning pin 42 on the heat dissipation element 40 extends into the positioning hole 12 of the bracket 10 to achieve positioning. The heat dissipation element 40 and the bracket 10 are engaged in the first direction F1 by the second mounting rib 41 and the second buckle 11. In this way, the bracket 10 and the heat dissipation element 40 can be positioned in the second direction F2 to avoid the two from shifting in the second direction F2 and affecting the projection of light.

[0054] After the heat dissipation element 40 is installed with the primary optical element 20 and the bracket 10, the desired result is obtained. Figure 1 The optical module shown.

[0055] The optical module of this application can be used not only in the corner lights of vehicle lights, but also in the headlights or other lighting applications of vehicles. This application does not make any specific limitations on this application.

[0056] In some scenarios, embodiments of this application also disclose a vehicle light, including any of the optical modules described above.

[0057] The headlight incorporates the same structure and beneficial effects as the optical module in the aforementioned embodiments. The structure and beneficial effects of the optical module have been described in detail in the preceding embodiments and will not be repeated here.

[0058] On the other hand, in other scenarios, embodiments of this application also disclose an optical component that uses a lens to enable the left and right headlights of a vehicle to project asymmetrical light patterns that are symmetrical to each other.

[0059] Specifically, the optical components disclosed in this application include optical modules respectively disposed in the left and right headlights of the vehicle. Each optical module includes at least a lens 60. The lens 60 of the left headlight's optical module is rotated 180° around a rotation axis parallel to the vehicle's X-axis to obtain the installation state of the lens 60 of the right headlight's optical module. The light patterns formed by the light rays emitted along the first direction F1 from the optical modules of the left and right headlights are both asymmetrical light patterns, which are symmetrical about the vehicle's XZ plane. It should be noted that the coordinate axis directions of the vehicle coordinate system are determined based on the driver's perspective: such as... Figure 15As shown, the X-axis is the longitudinal direction, aligned with the vehicle's centerline; the Y-axis is the lateral direction, located in the same plane perpendicular to the X-axis, pointing to the left; the Z-axis is the vertical direction, perpendicular to the XY plane, pointing upwards. The origin of the coordinate system is located at the vehicle's center of mass. Furthermore, an asymmetric light pattern refers to a light pattern formed on a beam distribution screen that is asymmetrical about the V-axis. The beam distribution screen is a vertical screen located 25 meters in front of the vehicle. The V-axis is the longitudinal axis of the beam distribution screen, and the H-axis is the transverse axis of the beam distribution screen; their intersection is the HV point.

[0060] The aforementioned optical modules are applied to the left and right headlights of the vehicle, respectively. During installation, the lens 60 of one optical module is rotated 180° around a rotation axis parallel to the vehicle's X-axis to obtain the installation state of the lens 60 of the other optical module. In other words, the lens 60 of one optical module can be directly mounted onto the other optical module after rotation. The lens 60 has an inner surface 61 and an outer surface arranged sequentially along the first direction F1. The inner surface 61 is used to receive light, and the outer surface is used to emit light. The inner surface 61 of the lens 60 is asymmetrically arranged about the optical axis s of the lens. It should be noted that the extension direction of the optical axis s of the lens is approximately the first direction F1, which is approximately the X-axis direction of the vehicle. Similarly, the second direction F2 is approximately the Z-axis direction of the vehicle, and the third direction F3 is approximately the Y-axis direction of the vehicle. The first direction F1, the second direction F2, and the third direction F3 are perpendicular or approximately perpendicular to each other.

[0061] The inner surface 61 of the lens 60 is the surface facing the light source 50, such as... Figure 1 As shown, the light emitted from the light source 50 is converged by the primary optical element 20 and then projected onto the inner surface 61 and outer surface of the lens 60 to form a light pattern. The inner surface 61 of the lens 60 is asymmetrical about the optical axis s of the lens, and the left and right directions are also the Y-axis direction of the vehicle.

[0062] This application sets the inner surface 61 of the lens 60 as a surface that is asymmetrical about the optical axis s of the lens, such as... Figure 8 This shows the state of the optical module when the left headlight is installed. Figure 9 The diagram illustrates the state of the optical module when the right headlight is installed. Since the inner surface 61 of the lens 60 is asymmetrical about the optical axis s of the lens, the light pattern formed by the optical module in either the left or right headlight, i.e., in a single optical component, is asymmetrical. The lens 60 of the optical module of the left headlight is rotated 180° around a rotation axis parallel to the X-axis of the vehicle to obtain the installation state of the lens 60 of the optical module of the right headlight. The light patterns formed by the optical modules in the left and right headlights are symmetrical about the XZ plane of the vehicle.

[0063] Therefore, the optical component of this application, by using a lens 60 that can realize asymmetrical light patterns, and by rotating the lens 60 of the optical module installed in the left headlight by 180° around a rotation axis parallel to the X-axis of the vehicle to obtain the installation state of the lens 60 of the optical module in the right headlight, can realize that only one lens 60 is used to project light patterns that are asymmetrical but symmetrical about the XZ plane of the vehicle. This solves the problem in the prior art that it is impossible to use the same lens to take into account the asymmetrical light patterns emitted by the left and right headlights of the vehicle respectively.

[0064] like Figure 10 The light pattern emitted from the optical module of the left headlight is shown. Figure 11 The light pattern emitted from the optical module of the right headlight is shown, and both are symmetrical about the XZ plane of the vehicle. The so-called asymmetrical light pattern in this application refers to the light pattern emitted from the optical module of the left headlight having a wider left side, and the left and right sides are not symmetrical about the V-axis. Similarly, the light pattern emitted from the optical module of the right headlight has a wider right side, and the left and right sides are not symmetrical about the V-axis. Furthermore, during the assembly of the optical modules, the use of the error-proofing structure of the jig 100 ensures accurate assembly of the optical modules of the left and right headlights, clearly indicating whether the optical module of the left or right headlight is being assembled. From a practical production perspective, this also ensures that the same optical module can be used to achieve asymmetrical light patterns for both the left and right headlights, but with symmetry about the XZ plane of the vehicle.

[0065] For example, the bracket 10 of the optical module is connected to the lens 60. The bracket 10 of the optical modules of the left and right headlights can also be the same. Specifically, the lens 60 and bracket 10 of the optical module of the left headlight are rotated 180° around a rotation axis parallel to the X-axis of the vehicle to obtain the installation state of the lens 60 and bracket 10 of the optical module of the right headlight.

[0066] The bracket 10 is equipped with a mistake-proof structure. After the bracket 10 aligns with the fixture 100 through the mistake-proof structure, it is assembled with other components. Since the lens 60 and bracket 10 of the optical module installed in the left and right headlights of the vehicle are rotated 180° around a rotation axis parallel to the X-axis of the vehicle to obtain the installation state of the lens 60 and bracket 10 of the optical module of the right headlight, but the light patterns formed by each are asymmetrical, even if the structures of the lens 60 and bracket 10 on both sides are identical, it is still necessary to avoid the situation of being installed backwards during assembly. By setting up the mistake-proof structure, this situation can be avoided.

[0067] The error-proofing structure includes a raised rib 13 and / or a marking. When the error-proofing structure includes a raised rib 13, a corresponding groove 101 is provided on the jig 100. Through the cooperation between the raised rib 13 and the groove 101, the bracket 10 is aligned with the jig 100 and then assembled with other components.

[0068] The ribs 13 on the bracket 10 can prevent left and right misalignment. The fixture 100 has grooves 101 that match the ribs 13. When assembling the optical module, the asymmetrical ribs 13 can prevent the bracket 10 from being installed backwards, ensuring that the optical modules on the left and right sides will not be confused during assembly. This allows the same lens 60 and bracket 10 to be used in both the left and right headlights and to achieve asymmetrical light patterns, thus saving costs.

[0069] like Figure 12 The image shows the state of bracket 10 during the assembly of the optical module for the left headlight, as shown. Figure 13 The diagram shows the state of bracket 10 during the assembly of the optical module for the right headlight. Figure 12 The structure shown can be obtained by flipping it 180°. Figure 13 The structure shown is composed of Figure 12 , Figure 13 As can be seen, the position of the protruding rib 13 changes after flipping. The protruding ribs 13 in different positions correspond to the jig 100 to prevent reverse installation.

[0070] from Figure 12 , Figure 13 It can also be seen that, in addition to the rib 13, the error-proofing structure also includes markings, which are used to identify the assembly direction of the left and right optical modules respectively. For example, the letters L (left) and R (right) or up and down arrows can be used as markings for assembling the left and right optical modules to prevent errors.

[0071] like Figure 12 , Figure 13 As shown, the ribs 13 on the bracket 10 are symmetrically arranged along the center line of the bracket 10 in the second direction F2, as follows: Figure 9 As shown, the axis of symmetry s' of the rib 13 does not coincide with the optical axis s of the lens, that is, the axis of symmetry s' of the rib 13 deviates from the optical axis s of the lens. This will... Figure 12 The structure shown can only be obtained by flipping it. Figure 13 The structure shown is configured to prevent errors, ensuring that the axis of symmetry s' of the rib 13 is coaxial with the optical axis s of the lens. The rib 13 is positioned on the center line of the support 10 in the third direction F3, allowing for smooth operation before and after flipping. Figure 12 and Figure 13 The positions of the protruding ribs 13 shown in the figure overlap, which fails to serve the purpose of preventing assembly errors.

[0072] In addition, the rib 13 can also be symmetrically arranged along the center line of the bracket 10 in the third direction F3 (not shown in the figure). Specifically, referring to the above arrangement, the rib 13 is not arranged on the center line of the bracket 10 in the second direction F2, but is arranged at a position away from the center line of the bracket 10 in the second direction F2, so as to achieve assembly error prevention.

[0073] In the assembly of the optical module of this application, the first step is to assemble the lens 60 and the bracket 10. The lens 60 and the bracket 10 can be formed into a single piece by two-color injection molding, or other assembly methods can be used.

[0074] The second step is to assemble the primary optical element 20 and the heat dissipation element 40, specifically by using the aforementioned pin 21 and the first pin hole, the second pin hole 43, and the first buckle 22 and the first mounting rib 44 for assembly.

[0075] After completing the first and second steps, first combine the parts assembled in the second step. Figure 3 The assembly shown is fixed to the fixture. Then, in accordance with the fixture and the position of the groove 101 on the fixture, the assembly with the bracket 10 and lens 60 from the first step is installed accordingly. Figure 14 The position of the groove 101 shown will then be as follows: Figure 7 The assembly shown is installed onto the fixture; if the groove 101 is located on the other side of the fixture, then it will be installed as shown. Figure 7 The assembly shown in the diagram, after being rotated 180°, will appear as follows: Figure 8 The assembly shown is then mounted onto the fixture.
