Abstract

The invention discloses a coil structure of a voice coil motor, a zoom lens, a security camera and a terminal. The coil structure of the voice coil motor is applied to an optical zoom lens and comprises a mounting base, a circuit board and a coil. The mounting base is movably mounted in an inner cavity of a lens barrel in the length direction of the lens barrel of the optical zoom lens. The mounting base is provided with a first end face and a second end face which are oppositely arranged, a mounting hole is formed in the middle of the first end face in a penetrating mode and used for mounting a wafer, a mounting groove is further formed in the first end face and located on one side of the mounting hole, and a via hole is formed in the bottom of the mounting groove in a penetrating mode. The circuit board is arranged on the first end face. The coil is fixed in the mounting groove and is annularly arranged, a through hole communicated with the via hole is formed in the middle of the coil, a magnetic part of the voice coil motor penetrates through the through hole, the coil is provided with a lead which is connected to the circuit board, the coil and the circuit board are located on the same side of the mounting base, the lead of the coil is short, materials are saved, and connection is convenient.

Description

technical field [0001] The invention relates to the field of voice coil motors, in particular to a coil structure of a voice coil motor, a zoom lens, a security camera and a terminal. Background technique [0002] With the rapid development of technology, zoom lenses have been widely used in security cameras and terminals. Voice coil motors have a good zoom effect as a driving device, but multiple structures need to be designed on the zoom lens, such as the lens installation structure, lens position detection structure, The installation structure of the magnet and the coil of the voice coil motor is complex in structure, takes up a large space, and is inconvenient to connect the coil to the circuit board. Contents of the invention [0003] The main purpose of the present invention is to provide a coil structure of a voice coil motor, a zoom lens, a security camera and a terminal, aiming at solving the problem of inconvenient connection between the coil of a voice coil moto...
