Description
Technical field
The present invention relates to a kind of dust-proof VCM structures, belong to voice coil motor design technical field.
Background technology
Voice coil motor is a kind of motion for converting electrical energy into the device of mechanical energy, and realizing linear pattern and limited pivot angle.
Produced using the interaction between magnetic pole in magnetic field caused by the magnetic field from permanent-magnet steel and hot-wire coil conductor regular
The device of motion.Because voice coil motor is a kind of non-inverting type power set, its positioning precision depends entirely on feedback and control
System, it is unrelated with voice coil motor itself.It can be easily reached using suitable position feedback and induction installation its positioning precision
10NM, acceleration is up to 300g.
At present, lens focusing is automatically adjusted using voice coil motor more, and voice coil motor carrier is connected with camera lens, is driven
Camera lens moves up and down in housing, due to existing voice coil motor sealing structure imperfection, usually has dust and passes through carrier and shell
Gap between body is dropped on chip, causes imaging shadow occur, influences imaging effect.
The content of the invention
Purpose：In order to overcome the deficiencies in the prior art, the present invention provides a kind of dust-proof VCM structures.
Technical scheme：In order to solve the above technical problems, the technical solution adopted by the present invention is：
A kind of dust-proof VCM structures, including：Shell body, base body, carrier, the shell body top are symmetrically arranged with four claws,
The carrier lateral wall sets inside claw groove with claw correspondence position, and claw groove is inserted from carrier top for claw
It is interior；The coil recess of outwardly convex is provided between the carrier median catch groove, coil is provided with the coil recess；
The carrier top is provided with the first shell fragment；Dust ring protruding upward, dust ring top are provided with the carrier bottom end opening
Symmetrical two L-type grooves are provided between portion and inwall, the base body open top end is set with L-type groove corresponding position
There is inserted block, for phase clamping between dust ring and base body opening；The dust ring outer wall bottom is provided with fixed column, described solid
The second shell fragment is provided with fixed column；The shell body outer wall is connected on base body.
Preferably, the dust ring internal diameter is more than the external diameter of carrier bottom end opening.
Preferably, the dust ring top is additionally provided with precompressed projection, the base body opening outer wall bottom pair
Answer and precompressed groove is provided with precompressed bump position, for dust ring and base body precompressed clamping.
Preferably, three precompressed projections are provided with the dust ring, three precompressed projections are symmetric.
Preferably, the carrier base is provided with detent, is mutually positioned with carrier for base body.
Preferably, the carrier base also sets up identification mark, for coordinating quick assembling.
Beneficial effect：A kind of dust-proof VCM structures provided by the invention, the structure to be cooperated by claw, claw groove,
The stability of mobile clamping between shell body and carrier can be effectively improved；Carrier base dust ring, and the setting of structure thereon, can
The sealing effectiveness between carrier and base body is effectively improved, reduces the movement due to carrier, the dust brought enters asking for chip
Topic, meanwhile, the other structures in carrier base, it can further improve the stability of mobile clamping between carrier and base seat.This
Design structure is stable, is easily assembled, good dustproof effect.
