The invention relates to the technical field of vehicle-mounted photoelectric rotary tables, in particular to a multifunctional unlocking and locking mechanism for a vehicle-mounted photoelectric rotary table, which comprises a head assembly, an azimuth rotary table, a pitching frame and a locking mechanism, the locking mechanism comprises a support, a bearing, an inner shaft, an outer shaft, a worm, a worm gear, a motor, end face teeth, a limiting nail, a spring and a limiting block. A support is installed in the bottom wall of the pitching frame, an outer shaft is installed in an axial hole of the support through a bearing, an inner shaft is slidably inserted in a hollow hole of the outer shaft, the top end face of the outer shaft is meshed with the inner shaft through end face teeth, meanwhile, the outer shaft is embedded in a worm wheel, and the worm wheel is meshed with a worm. The device can be electrically or manually unlocked and locked, pitching and azimuth unlocking and locking functions can be realized at the same time, the problem that a turntable loses functions once a locking device fails is solved, the reliability is improved, and the cost is reduced.

    本发明涉及车载光电转台技术领域,特别涉及一种用于车载光电转台的多功能解闭锁机构,包括:头部组件、方位转台、俯仰架和闭锁机构,方位转台上驱动旋转设有俯仰架,俯仰架上通过转轴安装有头部组件,闭锁机构包括:支座、轴承、内轴、外轴、蜗杆、蜗轮、电机、端面齿、限位钉、弹簧和限位块;俯仰架的底壁内部安装有支座,支座的轴向孔内通过轴承安装有外轴,外轴的中空孔内滑动插接有内轴,且外轴的顶部端面通过端面齿啮合有内轴,同时外轴嵌设于蜗轮上,蜗轮与蜗杆相啮合;该装置即可电动亦可以手动解闭锁,可同时实现俯仰向和方位向解闭锁功能,解决了一旦因闭锁装置失效造成的转台丧失功能的问题,提高了可靠性,降低了成本。
