Description

矩形汽车前大灯LED透镜模组远近光自动调节机构
技术领域
本发明涉及一种矩形汽车前大灯LED透镜模组远近光自动调节机构，属于汽车灯具领域。
背景技术
目前，汽车前大灯LED透镜模组一般由透镜、遮光罩、支撑架、反光碗、LED芯片和散热块等组成，其中透镜和遮光罩为分体制造的两个部件，各部件要分别开发一副模具，提高了模具的制造成本，而两者在装配时，装配工序麻烦，且无法保证镜面安装的统一性，如有位置偏差，将导致光照射出去的位置会偏移，并导致折射出去的光分散，甚至出现漏光。因此，本申请人曾申请了一种中国专利号201821412337.3，名称为“带一体式配光镜的汽车前大灯LED透镜模组”的专利，其透镜为矩形透镜，聚光效果更好，照射出的光线更加清晰。但在实际产品中，汽车的前大灯有远近光，需要设计一种自动调节远近光的结构。同时，其透镜通过支撑架与散热块相固定，产品结构比较复杂。
发明内容
本发明的目的是为了克服已有技术的缺点，提供一种采用电磁阀带动自动调节远近光，透镜直接固定在散热支架上，构思巧妙，结构紧凑，成本省的矩形汽车前大灯LED透镜模组远近光自动调节机构。
本发明矩形汽车前大灯LED透镜模组远近光自动调节机构的技术方案是：包括矩形透镜和散热支架，散热支架中设置反光碗和LED灯珠组件，其特征在于所述的矩形透镜一侧设置开口，开口中设置远近光自动调节机构，所述的远近光自动调节机构包括在位于开口处的散热支架上设置固定板，固定板上安装电磁阀，固定板的前部两侧各设置连接片，两个连接片之间通过卡簧活动连接调节板，所述调节板上设有横杆，电磁阀的阀杆连接横杆。
本发明的矩形汽车前大灯LED透镜模组远近光自动调节机构，主要特点是在矩形透镜的一侧设置开口，开口处中设置电磁阀和调节板，远光时，电磁阀通电，阀杆带动横杆，横杆带动调节板通过卡簧转动，调节调节板的位置，即调节板不挡住光源直射，汽车前大灯远光；近光时，电磁阀断电，调节板在卡簧作用下自动复位，调节板挡住部分光源直射，汽车前大灯近光。本方案采用电磁阀直接驱动调节板调节，结构简单，驱动可靠，克服透镜内部空间限制，实现远近光自动调节，具有非常有益的积极效果。
本发明的矩形汽车前大灯LED透镜模组远近光自动调节机构，所述的阀杆上设置夹件，夹件夹住横杆，采用夹件夹持，连接、拆卸方便。所述的散热支架上设置折板和固定孔柱，折板上设有定位杆，固定板上设置定位孔，定位杆与定位孔相配合，固定板上制有固定孔，固定孔与固定孔柱通过螺钉相固定，安装方便、可靠。所述的散热支架上顶面四角各设置连接孔柱，矩形透镜的下底面四角各设置一体成型的连接孔座，连接孔柱与连接孔座由螺钉相固定，矩形透镜直接固定在散热支架上，无需支撑架，减少部件，简化结构，节省成本。所述的散热支架两侧设置均布的散热杆，散热效果好。所述的散热支架底部设置散热风扇，进一步提高散热性能。
