技术领域Technical field
本发明涉及车灯，具体地，涉及一种前照灯光学组件。此外，本发明还涉及一种包括所述前照灯光学组件的照明装置、前照灯和车辆。The invention relates to a vehicle lamp, in particular to a headlamp optical assembly. In addition, the present invention also relates to a lighting device, a headlamp, and a vehicle including the headlamp optical assembly.
背景技术Background technique
在车辆前照灯中的照明装置中，Matrix矩阵式前照灯照明装置能够将远光照明区域细分为多个照明区域，实现远光自适应功能，对车辆前方的目标物进行遮蔽，避免道路其他使用者炫目，提高驾驶安全。Among the lighting devices in the vehicle headlights, the Matrix headlight lighting device can subdivide the high-beam lighting area into multiple lighting areas, realize the high-beam adaptive function, and shield the target in front of the vehicle to avoid Other road users are dazzling, improving driving safety.
Matrix矩阵式前照灯照明装置中的初级光学元件(如反射镜、聚光元件)是Matrix矩阵式前照灯照明装置的核心部件，该初级光学元件需要对光源的出射光精确定向，产生中间光分布，并通过次级光学元件(如透镜)进一步调制以获得希望的光形分布，因此，初级光学元件和次级光学元件的制造精度以及装配精度的要求都非常高。但是，现有Matrix矩阵式前照灯照明装置中各部件之间的安装连接关系如下：支撑板通过螺钉固定连接于设置有电路板的散热器上，初级光学元件固定在支撑板上，压板盖设于初级光学元件上方并与支撑板通过螺钉固定连接，以将初级光学元件限位；次级光学元件安装在透镜支架的前端，透镜支架的后端与散热器固定连接。因安装的零部件数量较多，初级光学元件、次级光学元件和透镜支架间的相对位置的精确性受支撑板和压板之间、支撑板和散热器之间、透镜支架和散热器之间的多次定位安装连接的影响，即三者之间存在多次装配误差，造成各光学元件之间的相对位置精度不够高。The primary optical elements (such as reflectors and condensing elements) in the matrix headlight illuminating device are the core components of the matrix headlight illuminating device. The primary optical element needs to accurately orient the light emitted from the light source to produce intermediate The light distribution is further modulated by the secondary optical element (such as a lens) to obtain the desired light shape distribution. Therefore, the requirements for the manufacturing accuracy and assembly accuracy of the primary optical element and the secondary optical element are very high. However, the installation and connection relationship between the various components in the existing Matrix matrix headlamp lighting device is as follows: the support plate is fixedly connected to the heat sink provided with the circuit board by screws, the primary optical element is fixed on the support plate, and the pressure plate cover It is arranged above the primary optical element and is fixedly connected with the supporting plate through screws to limit the primary optical element; the secondary optical element is installed at the front end of the lens holder, and the rear end of the lens holder is fixedly connected with the heat sink. Due to the large number of installed parts, the accuracy of the relative positions between the primary optical element, the secondary optical element and the lens holder is affected between the support plate and the pressure plate, between the support plate and the heat sink, and between the lens holder and the heat sink. The influence of multiple positioning, installation and connection, that is, there are multiple assembly errors between the three, which causes the relative position accuracy between the optical elements to be insufficient.
基于上述原因，现有技术难以有效保证各光学元件之间的相对位置的较高精度。For the above reasons, it is difficult for the prior art to effectively ensure the relatively high accuracy of the relative positions between the optical elements.

It should be understood that the specific embodiments described here are only used to illustrate and explain the present invention, and the scope of protection of the present invention is not limited to the following specific embodiments. .
在本发明的描述中，需要解释的是，术语“前”、“后”等指示的方位或位置关系为基于附图所示的方位或位置关系，仅是为了便于描述本发明的简化描述，本发明中前后指的是光线经聚光元件1汇聚后主要传输方向的光路，光线入射的一端为后端，光线出射的一端则为前端，即光源5所在的一端为后端，次级光学元件3所在的一端为前端。In the description of the present invention, it needs to be explained that the orientation or positional relationship indicated by the terms "front", "rear", etc. is based on the orientation or positional relationship shown in the drawings, and is only a simplified description for the convenience of describing the present invention. In the present invention, the front and back refers to the light path in the main transmission direction after the light is condensed by the condensing element 1, the end where the light enters is the back end, and the end where the light exits is the front end, that is, the end where the light source 5 is located is the back end, and the secondary optics The end where the element 3 is located is the front end.
在本发明的描述中，还需要说明的是，除非另有明确的规定和限定，术语“安装”、“连接”应做广义理解，例如，可以是固定连接，也可以是可拆卸连接，或者是一体连接；可以是直接连接，也可以是通过中间媒介 间接连接，可以是两个元件内部的连通或两个元件的相互作用关系。对于本领域的普通技术人员而言，可以根据具体情况理解上述术语在本发明中的具体含义。In the description of the present invention, it should also be noted that, unless otherwise clearly specified and limited, the terms "installation" and "connection" should be understood in a broad sense, for example, it can be a fixed connection or a detachable connection, or It is an integral connection; it can be a direct connection or an indirect connection through an intermediate medium, and it can be a communication between two elements or an interaction relationship between two elements. For those of ordinary skill in the art, the specific meanings of the above-mentioned terms in the present invention can be understood according to specific circumstances.
如图1至图6所示，本发明提供一种前照灯光学组件，包括聚光元件1和透镜支架2，其中所述透镜支架2上形成有适于容纳所述聚光元件1的空腔，该空腔内与所述聚光元件1上形成有适于相互嵌合的嵌合结构，所述聚光元件1通过所述嵌合结构嵌合在所述空腔内。As shown in Figures 1 to 6, the present invention provides a headlamp optical assembly, including a condenser element 1 and a lens holder 2, wherein the lens holder 2 is formed with a cavity suitable for accommodating the condenser element 1. In the cavity, a fitting structure suitable for mutual fitting is formed on the cavity and the light-concentrating element 1, and the light-concentrating element 1 is fitted into the cavity through the fitting structure.
在现有的前照灯光学组件中，聚光元件1和透镜支架2是构成前照灯光学组件的重要组成部分，两者之间为间接定位，这样会造成因多次定位形成安装误差，而聚光元件1和透镜支架2之间的安装精度直接会影响到前照灯的出光效果，因此，本发明的聚光元件1和透镜支架2上形成有相互嵌合的嵌合结构，而使得聚光元件1和透镜支架2直接连接定位，从而减少定位安装误差，提高两者之间的安装精度。In the existing headlamp optical assembly, the condensing element 1 and the lens holder 2 are important components of the headlamp optical assembly, and the two are positioned indirectly, which will cause installation errors due to multiple positioning. The installation accuracy between the condensing element 1 and the lens holder 2 will directly affect the light-emitting effect of the headlamp. Therefore, the condensing element 1 and the lens holder 2 of the present invention are formed with a mutual fitting structure, and The condensing element 1 and the lens holder 2 are directly connected for positioning, thereby reducing positioning and installation errors and improving the installation accuracy between the two.
本发明的聚光元件1和透镜支架2的嵌合可以有两种结构形式，作为其中一种结构形式，聚光元件1和透镜支架2优选形成为一体成型件，通过嵌合结构，聚光元件1和透镜支架2之间的定位精度更高。The condensing element 1 and the lens holder 2 of the present invention can be fitted in two structural forms. As one of the structural forms, the condensing element 1 and the lens holder 2 are preferably formed as an integral molded part, and the condensing structure The positioning accuracy between element 1 and lens holder 2 is higher.
在这里需要说明的是，因聚光元件1和透镜支架2为一体成型件，聚光元件1和透镜支架2可以采用同种材料，也可以采用不同材料。优选地，聚光元件1和透镜支架2选用不同的材料，聚光元件1可选用耐热性能、光学性能更佳的材料(比如硅胶)成型，透镜支架2可选用刚性更佳的材料(比如PC、PMMA等或其混合物)成型，以便于更好地支撑聚光元件1，增强其稳定性。It should be noted here that, because the condensing element 1 and the lens holder 2 are integrally formed, the concentrating element 1 and the lens holder 2 can be made of the same material or different materials. Preferably, the condensing element 1 and the lens holder 2 are made of different materials, the concentrating element 1 can be formed of materials with better heat resistance and optical performance (such as silica gel), and the lens holder 2 can be formed of materials with better rigidity (such as PC, PMMA, etc. or their mixtures) are molded to better support the light-concentrating element 1 and enhance its stability.
同时，透镜支架2和聚光元件1采用嵌件成型工艺一体成型，其成型工艺过程如图4、图6所示：首先，透镜支架2通过注塑成型；然后，将透镜支架2装入用于注塑聚光元件1的模具中，浇筑材料后即可得到透镜支架2和聚光元件1的一体成型件。当然，透镜支架2和聚光元件1间还可以采用其他可以实现该一体结构的成型工艺和方法，例如，也可以采用双 色注塑成型。At the same time, the lens holder 2 and the condensing element 1 are integrally formed by an insert molding process. The molding process is shown in Figure 4 and Figure 6. First, the lens holder 2 is molded by injection molding; then, the lens holder 2 is assembled for use. In the mold for the injection molding of the concentrating element 1, after pouring the material, an integral molded part of the lens holder 2 and the concentrating element 1 can be obtained. Of course, other molding processes and methods that can realize the integrated structure can also be used between the lens holder 2 and the condensing element 1, for example, two-color injection molding can also be used.
如图7和图8所示，作为本发明的一个优选实施方式，所述嵌合结构包括设于所述空腔的内周壁上的嵌入部201以及设于所述聚光元件1前端的嵌槽1014，同时，该嵌槽1014一体形成于所述聚光元件1的出光部的四周，由此，可以将嵌合结构设置在聚光元件1的前端，能够有效提高出光部1013的刚度。As shown in Figures 7 and 8, as a preferred embodiment of the present invention, the fitting structure includes an embedding portion 201 provided on the inner peripheral wall of the cavity and an embedding provided on the front end of the condensing element 1. At the same time, the embedding groove 1014 is integrally formed around the light-emitting part of the light-concentrating element 1, so that the fitting structure can be arranged at the front end of the light-concentrating element 1, and the rigidity of the light-emitting part 1013 can be effectively improved.
如图7所示，透镜支架2上形成有用于容置聚光元件1的空腔，并且该空腔是前后贯通的，在空腔的四周内侧壁上形成有嵌入部201，嵌入部201由四周向中心延伸，其沿所述空腔的内周壁环绕一周形成，呈薄板状，所述嵌入部201上形成有贯穿所述嵌入部201的多个通孔2011。As shown in Figure 7, a cavity for accommodating the light-concentrating element 1 is formed on the lens holder 2, and the cavity is penetrated back and forth.

如图15所示，作为本发明的一个具体结构形式，所述定位件4上设有多个隔筋402，相邻两个所述隔筋402之间形成有定位口401，各所述定位口401与所述光源5一一对应设置。As shown in Figure 15, as a specific structural form of the present invention, the positioning member 4 is provided with a plurality of spacer ribs 402, a positioning opening 401 is formed between two adjacent spacer ribs 402, and each of the positioning members The port 401 and the light source 5 are arranged in a one-to-one correspondence.
在上述技术方案中，聚光元件1的多个准直单元101之间形成有楔形间隙102，为了确保多个准直单元101的入光部1011与电路板6上的光源5的相对位置的精确性，本发明的照明装置内还设置了对各入光部1011定位的定位件4，该定位件4内设有若干隔筋402，相邻两个隔筋402之间构成供准直单元101穿过并定位的定位口401，定位口401与设置在电路板6上的光源5一一对应，多个准直单元101可以是一排排列，也可以是多排排列，相对应地，定位口401可以是一排排列，也可以是多排排列。各准直单元101的入光部1011可插入对应的定位口401而被定位，由此，聚光元件1的出光部1013和入光部1011均被定位，聚光元件1的前端与次级光学元件3直接定位，后端通过定位件4与光源5定位，从而能够有效提高聚光元件1的定位精度，改善了出光效果。In the above technical solution, a wedge-shaped gap 102 is formed between the multiple collimating units 101 of the light concentrating element 1, in order to ensure the relative position of the light incident portion 1011 of the multiple collimating units 101 and the light source 5 on the circuit board 6 Accuracy, the lighting device of the present invention is also provided with a positioning member 4 for positioning each light incident part 1011. The positioning member 4 is provided with a plurality of spacer ribs 402, and a collimating unit is formed between two adjacent spacer ribs 402.

The multiple collimating units 101 may be arranged in a row or in multiple rows, correspondingly, The positioning openings 401 may be arranged in one row or in multiple rows. The light incident portion 1011 of each collimating unit 101 can be inserted into the corresponding positioning opening 401 to be positioned. As a result, the light output portion 1013 and the light incident portion 1011 of the condensing element 1 are both positioned, and the front end of the condensing element 1 and the secondary The optical element 3 is directly positioned, and the rear end is positioned with the light source 5 through the positioning member 4, thereby effectively improving the positioning accuracy of the concentrating element 1 and improving the light output effect.
具体地，从图9至图12中可以看出，隔筋402呈隔板状，定位口401的横向截面宽度由前向后逐渐变窄，准直单元101的横向截面宽度也是由前向后逐渐变窄，但是定位口401的变窄程度比准直单元101的变窄程度更大，这样可以使得准直单元101与隔筋402的接触面积尽可能小，一方面，是便于插入时的导向，另一方面，小面积接触可以确保定位精度，因此，进一步具体地，准直单元101与隔筋402之间的接触为线接触。由此可以看出，隔筋402还可以为圆柱体，即隔筋402的截面形状为矩形或者圆形，与准直单元101形成线接触。Specifically, it can be seen from FIGS. 9 to 12 that the rib 402 is in the shape of a partition, the width of the transverse cross-section of the positioning opening 401 gradually narrows from front to back, and the width of the transverse cross-section of the collimating unit 101 is also from front to back. Gradually narrows, but the narrowing degree of the positioning opening 401 is greater than the narrowing degree of the collimating unit 101, so that the contact area between the collimating unit 101 and the rib 402 can be as small as possible. On the one hand, it is convenient for insertion Guiding, on the other hand, a small area contact can ensure positioning accuracy. Therefore, more specifically, the contact between the collimating unit 101 and the rib 402 is a line contact. It can be seen from this that the spacer rib 402 may also be a cylinder, that is, the cross-sectional shape of the spacer rib 402 is rectangular or circular, and forms a line contact with the collimating unit 101.

The installation of 7 is not in place.
作为本发明的又一个具体结构形式，所述透镜支架2的后端形成有翻边203，该翻边203的后侧侧面适于与所述电路板6贴靠。As another specific structural form of the present invention, a flange 203 is formed at the rear end of the lens holder 2, and the rear side of the flange 203 is suitable for abutting against the circuit board 6.
