Abstract

The invention discloses a dustproof VCM structure, which comprises an outer shell, a base body and a carrier, and is characterized in that four claws are symmetrically arranged at the top end of the outer shell, the outer side wall of the carrier is provided with inward claw grooves at positions corresponding to the claws, and the claws are inserted into the claw grooves from the top of the carrier; the middle part of the carrier is provided with outwardly protruding coil grooves between the claw grooves, and the coil grooves are internally provided with a coil; the top of the carrier is provided with a first elastic piece; the bottom end of the carrier is provided with an upwardly protruding dustproof ring at the opening, two symmetric L-shaped grooves are arranged between the top and the inner wall of the dustproof ring, the top end of the opening of the base body is provided with insertion blocks at positions corresponding to the L-shaped grooves, and the insertion blocks are used for clamping connection between the dustproof ring and the opening of the base body; the bottom of the outer wall of the dustproof ring is provided with fixing columns, and each fixing column is provided with a second elastic piece; and the outer wall of the outer shell is clamped on the base body. The dustproof VCM structure provided by the invention is stable in structure, easy to assemble and good in dustproof effect.

Description

technical field [0001] The invention relates to a dust-proof VCM structure, which belongs to the technical field of voice coil motor design. Background technique [0002] A voice coil motor is a device that converts electrical energy into mechanical energy, and realizes linear and limited swing angle motion. A device that uses the interaction between the magnetic field from the permanent magnet steel and the magnetic poles in the magnetic field generated by the energized coil conductor to produce regular motion. Because the voice coil motor is a non-commutating power device, its positioning accuracy depends entirely on the feedback and control system, and has nothing to do with the voice coil motor itself. With appropriate positioning feedback and sensing devices, the positioning accuracy can easily reach 10NM, and the acceleration can reach 300g. [0003] At present, the focus of the lens is automatically adjusted by the voice coil motor. The carrier of the voice coil mot...
