The optical element of the headlight can distribute the light emitted by the light source (such as focusing, collimation, etc.), and therefore, the optical element of the headlight has a significant influence on the lighting effect of the headlight.
现有的车灯光学元件一般采用聚碳酸酯(PC)材料或者聚甲基丙烯酸甲酯(PMMA)材料制成，虽然能够保证安装的可靠性，但是，耐热性相对较差，由于车灯光学元件的入光端紧靠光源，长时间使用后容易使车灯光学元件受热变形，甚至使车灯光学元件烧坏，从而影响车灯光学元件的光学性能。The optical components of the existing car lights are generally made of polycarbonate (PC) material or polymethyl methacrylate (PMMA) material. Although the reliability of the installation can be guaranteed, the heat resistance is relatively poor. The light incident end of the optical element is close to the light source, and the optical element of the car light is easily deformed by heat after long-term use, and even the optical element of the car light is burned out, thus affecting the optical performance of the optical element of the car light.

通过上述技术方案，本发明的有益效果如下：Through the above-mentioned technical scheme, the beneficial effects of the present invention are as follows:
现有技术的车灯光学元件的光学主体和安装座由单一材料制成，例如，当制备材料采用硅胶时，硅胶材质的结构刚性相对较弱，容易影响安装精度，可靠性较低；当制备材料采用塑料时，虽然能够提升安装可靠性，但是，相对来说，塑料的耐高温性能较差，由于光学主体的入光端紧靠光源，经过一定时间的使用 之后，光源产生的热量容易导致光学主体变形，甚至烧坏，从而影响光学性能。相对于现有技术的车灯光学元件，本发明对光学主体和安装座分别采用不同的材料制备，具体地，光学主体采用耐高温透光材料制备，安装座采用塑料制备，这种结构能够保证安装可靠性的同时，降低高温对光学主体的影响，保证整体的光学性能；而且，不需要寻找耐候性高、耐温性高的新材料，利用现有材料，有效节约成本。The optical body and the mounting seat of the optical element of the vehicle light in the prior art are made of a single material. For example, when the preparation material is silica gel, the structural rigidity of the silica gel material is relatively weak, which easily affects the installation accuracy and has low reliability; When the material is made of plastic, although the installation reliability can be improved, relatively speaking, the high temperature resistance of plastic is poor. Since the light incident end of the optical body is close to the light source, after a certain period of use, the heat generated by the light source is easy to cause. The optical body is deformed or even burned out, thereby affecting the optical performance. Compared with the optical components of the vehicle light in the prior art, the present invention adopts different materials for the optical body and the mounting seat respectively. While the installation is reliable, the impact of high temperature on the optical main body is reduced, and the overall optical performance is ensured; moreover, there is no need to find new materials with high weather resistance and high temperature resistance, and the existing materials are used to effectively save costs.
有关本发明的其他优点以及优选实施方式的技术效果，将在下文的具体实施方式中进一步说明。Other advantages of the present invention and the technical effects of the preferred embodiments will be further described in the following specific embodiments.

The optical body is installed on the mounting seat, and the mounting seat is connected with other structures in the lamp to effectively ensure the installation accuracy of the optical body; compared with the existing single The optical element of the vehicle light prepared from the material has not only good installation reliability, but also good high temperature resistance performance, and the optical performance is effectively guaranteed. When the optical body and the mounting seat are injection-molded, the mounting seat is first injection-molded, and then the mounting seat is used as an insert when the optical body is injected, and the optical body and the mounting seat are injection-molded into one.
其中，耐高温透光材料可以为硅胶、玻璃等材料，塑料可以为聚碳酸酯(PC)材料或者聚甲基丙烯酸甲酯(PMMA)等材料。硅胶材料相比PC或PMMA等塑料的光学性能和耐热性能更好，PC或PMMA等塑料相比硅胶材料的结构刚性更好。Wherein, the high-temperature resistant and light-transmitting material may be a material such as silica gel or glass, and the plastic may be a material such as polycarbonate (PC) or polymethyl methacrylate (PMMA).

本发明的车灯光学元件的具体结构形式，多种多样。The specific structural forms of the optical element of the vehicle light of the present invention are various.
图1至图8示出了车灯光学元件的一种具体结构形式，安装座为第一安装结构1，光学主体可以由多个聚光单元3线性排列组成，参照图2，如各聚光单元3沿左右方向依次排列，且各聚光单元3的入光面相连为一体结构，各聚光单元3的出光面为向前凸出的曲面，使得各聚光单元3形成为一个凸透镜。曲面的形状可以根据所需要的像素光形的形状自由设置，具体可以设置为球面，也可以设置为椭球面或者自由曲面等。参照图9，各聚光单元3的出光面的左右宽度由一侧向另一侧逐渐增大，也就是说，光源71之间的间距由一侧向另一侧逐渐增 大。这样，经过透镜82的投射后，靠近车辆正前方的像素光形的宽度较小，远离车辆正前方的像素光形的宽度较大。此时，所形成的照明光形靠近车辆正前方的部分具有相对较高的像素分辨率，而照明光形远离车辆正前方的部分具有相对较低的像素分辨率。在实现ADB功能时，熄灭某个远光光源71时，在车辆正前方形成的照明暗区较小，而在车辆侧方形成的照明暗区较大，这样能够减小照明暗区对驾驶安全的影响。Figures 1 to 8 show a specific structural form of the optical element of the car light, the mounting base is the first mounting structure 1, and the optical body can be composed of a plurality of light-condensing units 3 linearly arranged. The units 3 are arranged in sequence along the left and right directions, and the light incident surfaces of the light collecting units 3 are connected into an integrated structure. The shape of the curved surface can be freely set according to the required shape of the pixel light shape, and specifically can be set as a spherical surface, or can be set as an ellipsoid surface or a free-form surface. Referring to FIG. 9 , the left and right widths of the light emitting surfaces of the light collecting units 3 gradually increase from one side to the other side, that is, the distance between the light sources 71 gradually increases from one side to the other side. In this way, after being projected by the lens 82, the width of the light shape of the pixel close to the front of the vehicle is smaller, and the width of the light shape of the pixel far from the front of the vehicle is larger. At this time, the portion of the formed illumination light pattern close to the front of the vehicle has a relatively high pixel resolution, and the portion of the illumination light pattern away from the front of the vehicle has a relatively low pixel resolution. When the ADB function is implemented, when a certain high-beam light source 71 is turned off, the lighting dark area formed directly in front of the vehicle is small, while the lighting dark area formed on the side of the vehicle is larger, which can reduce the lighting dark area for driving safety. Impact.
相应地，各聚光单元3形成的光学主体可以设置在第一安装结构1的中部，第一安装结构1通过嵌合结构与光学主体嵌合；具体地，参照图4至图6，嵌合结构包括嵌合部22以及嵌合孔21，参照图5，第一安装结构1的中部形成一个安装孔，安装孔的周边形成有至少一个嵌合孔21，对应地，参照图6，光学主体的周边形成有至少一个嵌合部22，使第一安装结构1与光学主体能够嵌合在一起；可以理解的是，嵌合孔21设置在安装孔上的位置以及嵌合部22设置在光学主体上的位置，也可以改变，主要能够实现第一安装结构1与光学主体的嵌合即可；而且，也可以将嵌合部22与嵌合孔21的安装位置进行对换，即嵌合孔21设置在光学主体上，嵌合部22设置在第一安装结构1上。通过嵌合结构，能够增加第一安装结构1与光学主体两者之间的接触面积，以提高两者之间的结合强度。Correspondingly, the optical main body formed by each concentrating unit 3 can be arranged in the middle of the first installation structure 1, and the first installation structure 1 is fitted with the optical main body through a fitting structure; The structure includes a fitting portion 22 and a fitting hole 21. Referring to FIG. 5, a mounting hole is formed in the middle of the first mounting structure 1, and at least one fitting hole 21 is formed at the periphery of the mounting hole. Correspondingly, referring to FIG. 6, the optical body At least one fitting portion 22 is formed on the periphery of the optic, so that the first mounting structure 1 and the optical body can be fitted together; The position on the main body can also be changed, mainly to realize the fitting of the first installation structure 1 and the optical main body; moreover, the installation positions of the fitting part 22 and the fitting hole 21 can also be exchanged, that is, fitting The hole 21 is provided on the optical body, and the fitting portion 22 is provided on the first mounting structure 1 . Through the fitting structure, the contact area between the first installation structure 1 and the optical body can be increased, so as to improve the bonding strength between the two.
根据需要，光学主体也可以设置在第一安装结构1上的其它位置，如上部、下部等。According to requirements, the optical body can also be arranged at other positions on the first installation structure 1, such as the upper part, the lower part, and the like.

其中，光学主体包括导光部5和融合出光部6，导光部5的出光端与融合出光部6的入光端连接，融合出光部6沿上下方向的厚度大于导光部5沿上下方向的厚度。光源发出的光线经导光部5入射至融合出光部6内，融合出光部6 能够将传输至该融合出光部6的光线进行融合后出射。由于融合出光部6的厚度增高，使得从其出光面出射的光线更加扩散，有利于光形的上边界下方的光形柔化。其中，融合出光部6的融合作用指的是将传输至该融合出光部6的光线融合后再传输至其出光面。The optical body includes a light guide portion 5 and a fusion light exit portion 6 , the light exit end of the light guide portion 5 is connected to the light entrance end of the fusion light exit portion 6 , and the thickness of the fusion light exit portion 6 along the up-down direction is greater than that of the light guide portion 5 along the up-down direction. thickness of. The light emitted by the light source is incident into the fusion light part 6 through the light guide part 5 , and the fusion light part 6 can fuse the light transmitted to the fusion light part 6 and then exit. Since the thickness of the fusion light-emitting portion 6 is increased, the light emitted from the light-emitting surface thereof is more diffused, which is beneficial to the softening of the light shape below the upper boundary of the light shape. Wherein, the fusion effect of the fusion light part 6 refers to the fusion of the light transmitted to the fusion light part 6 and then transmitted to the light emitting surface thereof.
具体地，参照图13和图15，导光部5包括线性排列的多个导光柱，各导光柱的出光端与融合出光部6的入光端相连。Specifically, referring to FIGS. 13 and 15 , the light guide portion 5 includes a plurality of linearly arranged light guide columns, and the light exit end of each light guide column is connected to the light entrance end of the merged light exit portion 6 .
进一步地，各导光柱包括两个侧边导光柱51和至少一个中间导光柱52，至少一个中间导光柱52沿左右方向依次排列在两个侧边导光柱51之间，侧边导光柱51的外侧面设置为由后向前向外延伸且延伸至融合出光部6，例如，参照图15，侧边导光柱51的外侧面设置为从该侧边导光柱51的后端先沿直线向前延伸、再沿曲线向外侧弯曲延伸至融合出光部6的后侧。侧边导光柱51的外侧面具体指的是该侧边导光柱51上远离中间导光柱52的侧面，例如位于左侧的侧边导光柱51的外侧面即为该侧边导光柱51的左侧面。各导光柱设置为沿左右方向依次排列，使得光学主体能够满足车灯造型的小型化和扁平化的结构设计要求，同时侧边导光柱51的外侧面设置为从后端先沿直线向前延伸、再沿曲线向外侧弯曲延伸至融合出光部52的后侧，使得侧边导光柱51的外侧轮廓向两侧逐渐弯曲，能够增加光形两侧的照明范围，改善光形效果。Further, each light guide column includes two side light guide columns 51 and at least one middle light guide column 52. The at least one middle light guide column 52 is sequentially arranged between the two side light guide columns 51 along the left-right direction. The outer side is arranged to extend from the back to the front and outward to the fusion light portion 6. For example, referring to FIG. 15 , the outer side of the side light guide column 51 is set to go forward in a straight line from the rear end of the side light guide column 51. Extend, and then bend outward along the curve to extend to the rear side of the fusion light-emitting part 6 . The outer side of the side light guide column 51 specifically refers to the side of the side light guide column 51 away from the middle light guide column 52 . For example, the outer side of the side light guide column 51 on the left side is the left side of the side light guide column 51 side. Each light guide column is arranged in order along the left and right direction, so that the optical body can meet the requirements of the miniaturization and flat structure design of the lamp shape. At the same time, the outer side of the side light guide column 51 is set to extend straight forward from the rear end. , and then bend to the outside along the curve and extend to the rear side of the fusion light emitting part 52, so that the outer contour of the side light guide column 51 is gradually curved to both sides, which can increase the illumination range on both sides of the light shape and improve the light shape effect.
在图10所示的车灯光学元件的具体结构形式的基础上，可以对第二安装结构4的结构进行一定改变，形成图17所示的车灯光学元件的另一种具体结构形式，两者的主要区别在于，在图17的实施例中，第二安装结构4去除了两侧的安装板，并在其侧壁上设置了卡槽42，与光学主体支架9能够卡合在一起，两者形成一种车灯光学元件组件。其中，参照图16，光学主体支架9上形成有光学主体容纳腔，光学主体容纳腔后端上设置有多个截面周长由后向前逐渐增大的正棱台形通孔，每个正棱台形通孔的后端开口设置为能够对导光柱进行限位的导光柱限位孔91，当本发明的车灯光学元件插接在光学主体容纳腔内时，导光柱能够插入各自对应的导光柱限位孔91内。导光柱限位孔91能够对相应的导光柱起到限位作用，确保导光柱后端的导光口相对光源的位置精度。优选情况下，正棱台形通孔的数量大于或等于导光柱的数量。On the basis of the specific structural form of the optical element of the headlight shown in FIG. 10 , the structure of the second installation structure 4 can be changed to form another specific structural form of the optical element of the headlight shown in FIG. 17 . The main difference between the two is that, in the embodiment of FIG. 17, the second mounting structure 4 has removed the mounting plates on both sides, and is provided with a card slot 42 on its side wall, which can be snapped together with the optical main body bracket 9, The two form a vehicle light optical component assembly. 16 , an optical main body accommodating cavity is formed on the optical main body support 9, and a plurality of regular prismatic through holes whose cross-sectional circumference gradually increases from the back to the front are arranged on the rear end of the optical main body accommodating cavity.

When the optical element of the vehicle light of the present invention is inserted into the optical body accommodating cavity, the light guide column can be inserted into the corresponding guide column. in the beam limiting hole 91 . The limiting hole 91 of the light guide rod can limit the position of the corresponding light guide rod, so as to ensure the positional accuracy of the light guide port at the rear end of the light guide rod relative to the light source. Preferably, the number of regular prismatic through holes is greater than or equal to the number of light guide columns.
参照图18和图19，为了便于光学主体与光学主体支架9的安装连接，光 学主体容纳腔内设置有支撑板92，支撑板92能够插接在光学主体下表面与第二安装结构4之间形成的通孔41内，从而将融合出光部6支撑在支撑板92上，在光学主体从光学主体支架9前侧插入光学主体容纳腔时，相应地，支撑板92插接在光学主体下表面与第二安装结构4之间形成的通孔41内，融合出光部6支撑在支撑板92上，使得光学主体与光学主体支架9的安装连接更加稳固，从而提高光学主体的光学效率。18 and 19 , in order to facilitate the installation and connection of the optical main body and the optical main body bracket 9 , a supporting plate 92 is provided in the optical main body accommodating cavity, and the supporting plate 92 can be inserted between the lower surface of the optical main body and the second installation structure 4 In the through hole 41 formed, the fusion light part 6 is supported on the support plate 92. When the optical body is inserted into the optical body accommodating cavity from the front side of the optical body bracket 9, the support plate 92 is correspondingly inserted on the lower surface of the optical body.
