The invention discloses an automatic hidden lifting point mechanism for an underwater vehicle. The automatic hidden lifting point mechanism comprises a cylinder body, an end cover, a lifting rod, a lifting ring and an elastic piece, the barrel is used for being fixed to the upper end of an underwater vehicle, the lower end of the suspender is arranged on the inner side of the barrel, the upper end of the suspender movably penetrates through the upper end of the barrel and then extends out of the barrel, an annular convex edge is arranged on the outer wall of the suspender located on the inner side of the barrel, a sealing assembly is fixed to the outer top of the barrel, and the suspender movably penetrates through the sealing assembly. The end cover is fixed to the lower end of the cylinder in a sealed mode, the elastic piece is arranged on the inner side of the cylinder, the upper end of the elastic piece abuts against the lower end of the annular convex edge, the lower end of the elastic piece abuts against the upper end of the end cover, the hanging ring is fixed to the upper end of the hanging rod, and after the hanging rod moves downwards in place, the molded line of the upper end of the hanging ring coincides with the contour line of the upper end of the underwater vehicle. After the device is fixed to the upper end of the underwater vehicle and the underwater vehicle dives below a certain water depth, the hanging ring can be hidden.

    本发明揭示一种水下航行器用自动隐藏式吊点机构,包括筒体、端盖、吊杆、吊环和弹性件;筒体用于固定在水下航行器的上端,吊杆的下端设置在筒体的内侧,吊杆的上端活动贯穿筒体的上端后伸出于筒体外,位于筒体内侧的吊杆的外壁上设置有环形凸边,筒体的外顶部上固定有密封组件,吊杆活动穿设在密封组件中,端盖密封式地固定在筒体的下端,弹性件设置在筒体的内侧,弹性件的上端与环形凸边的下端相抵靠,弹性件的下端与端盖的上端相抵靠,吊环固定在吊杆的上端,当吊杆向下移动到位后,吊环上端的型线与水下航行器上端的轮廓线重合;本发明在固定到水下航行器的上端后,当水下航行器下潜到一定的水深以下后,能够实现对吊环的隐藏。
