The invention discloses a lens focusing system, and relates to the technical field of automobile illumination. The lens focusing system comprises a lens support, a lens slidably arranged on the lens support in the focusing direction and a focusing device, the focusing device comprises a lens flat pressing assembly and a lens side pushing assembly, and the lens flat pressing assembly is used for pressing the lens on the lens support in the pressing direction perpendicular to the focusing direction. The lens side pushing assembly is used for pushing the lens to move relative to the lens support in the focusing direction to achieve focusing. The lens focusing system not only can solve the difficulty of high-precision focusing in the prior art, but also has the function of fastening after focusing, and solves the problem that a traditional projector lens is difficult to be used in a high-speed and violent vibration environment when being applied to a vehicle.

    本申请公开一种镜头调焦系统,涉及汽车照明技术领域。该镜头调焦系统包括镜头支架、沿调焦方向滑动设置在镜头支架上的镜头以及调焦装置,调焦装置包括镜头平压组件和镜头侧推组件,镜头平压组件用于沿与调焦方向垂直的压紧方向将镜头压紧在镜头支架上,镜头侧推组件用于沿调焦方向推动镜头相对镜头支架移动实现调焦。该镜头调焦系统既能够解决现有技术中高精度调焦的难点,又具有调焦后紧固的功能,解决了传统投影仪镜头应用于车辆时难以满足在高速、剧烈振动的环境中使用的问题。
