Problems solved by technology

[0004] The main purpose of the present invention is to propose a self-locking structure of a zoom lens, lens and shooting equipment, aiming to solve the problem that the moving group in the lens barrel will slide freely within the range of the front and rear mechanical dead points during the transportation or movement of the lens. The front and rear dead points of hard impact will cause the lens to be smashed, the black object mechanism to break and other lens damage problems

Embodiment Construction

[0040] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.

[0041] It should be noted that if there is a directional indication (such as up, down, left, right, front, back...) in the embodiment of the present invention, the directional indication is only used to explain the position in a certain posture (as shown in the accompanying drawing). If the specific posture changes, the directional indication will also change accordingly.

[0042] In addition, if there are descriptions involving "first", "second" and ...

Abstract

The invention discloses a zoom lens self-locking structure, a lens and a shooting device, the self-locking structure of the zoom lens comprises a lens barrel, a moving carrier, a self-locking mechanism and a deformation driving member, the lens barrel is provided with an inner cavity; the moving carrier is movably installed in the inner cavity along the length direction of the lens cone. The self-locking mechanism comprises a locking part and a matching part, one of the locking part and the matching part is arranged on the lens cone, the other one of the locking part and the matching part is arranged on the moving carrier, the locking part is movably arranged to be matched with the matching part for locking or separating, and when the matching part is locked, the movement of the mobile carrier on the lens cone is limited; and the deformation driving piece is used for driving the locking part to move to be locked and matched with the matching part through deformation, so that the movement of the moving carrier on the lens barrel is limited, the moving carrier is effectively locked, the phenomena that the lens is crashed and the black object mechanism is broken due to collision are avoided, and the service life is prolonged.

Description

technical field [0001] The invention relates to the technical field of electronic equipment, in particular to a self-locking structure of a zoom lens, a lens and a shooting device. Background technique [0002] A zoom lens is a camera lens that can change the focal length within a certain range, so as to obtain different wide and narrow field of view angles, different size images and different scene ranges. The zoom lens can change the shooting distance by changing the focal length without changing the shooting distance. scope. [0003] In the optical zoom lens based on the VCM motor, two parallel guide shafts are fixed in the lens barrel, and the moving group slides on the two guide shafts, and its moving range is limited by the front and rear mechanical dead points in the lens barrel. The power source for the movement of the moving group is the VCM motor. The mover and the stator of the VCM motor are non-contact. When the coil is not energized, the VCM motor cannot self-l...
