Abstract

The invention relates to a four-link elastic switching mechanism, which belongs to the technical field of optical-mechanical structures and solves the technical problems of low transmission efficiency and slow switching speed in the prior art; the invention includes a crank, a connecting rod, a rocker, a frame and an elastic hinge pin The crank is hinged to the connecting rod, the connecting rod is connected to the rocker through an elastic hinge pin, the rocker is hinged to the frame, and the frame is hinged to the crank. The present invention utilizes the precise limit of the rocker, the slight overshoot of the crank and the elastic hinge pin to realize the precise positioning and safe locking of the switched object, and has the advantages of simple structure, reliable principle, and small mechanical impact; and the mechanism is compact in structure, through The rational layout and ingenious integration of the switched objects and the mechanism ensure high structural space utilization.

Description

technical field [0001] The invention belongs to the technical field of optical-mechanical structures, and in particular relates to a four-link elastic switching mechanism. Background technique [0002] Lens group switching is one of the main implementation methods of optical zoom. In order to ensure the imaging quality and work efficiency of the optical system, optical zoom has certain requirements for the position accuracy, self-locking ability and responsiveness of the lens group switching mechanism. Although both the horizontal push method and the rotation method can realize the switching of mirror groups, the horizontal push method has disadvantages such as large structural space and complicated limit locking mechanism. The rotation method is currently the main technical way to realize mirror group switching. Locking function, the rotation method needs to be used together with the worm gear drive to realize the position self-locking. By improving the machining accuracy o...
