It is corresponding with the magnet on wall.
The a kind of of the voice coil motor provided as the utility model improves, also including base, its dress relative with the shell
With fixation.
The utility model has the advantages that：Voice coil motor, that it changes the principle of existing spring-piece type voice coil motor,
By the use of flexible coil piece as the stator of voice coil motor, magnet simplifies the structure and accessory of voice coil motor as mover, while
Facilitate the assembling of motor.Magnet used as mover, easily by external magnetic field interference realized vibrating by mover, but mover no power, no
Need to weld mover, it is easy to assembly.Flexible coil piece need not be wrapped on carrier, can directly be fitted in shell inwall, and conduct
Stator also allows for being electrically connected with the mainboard on electronic equipment without vibration, good reliability.
Brief description of the drawings
Fig. 1 is the structure chart of the utility model voice coil motor；
Fig. 2 is the exploded view of the utility model voice coil motor.
Specific embodiment
The utility model is described in detail with reference to the accompanying drawings and examples.
As shown in Figure 1, 2, a kind of voice coil motor, it includes shell 1, the mirror for carrying camera lens being arranged in shell 1
Head carrier 5, the magnet 4 for being arranged on the outside of the camera lens carrier 5 and the flexible coil piece 3 being arranged on the inwall of the shell 1, institute
Shell fragment 2 and lower shell fragment 6 are stated respectively positioned at the both sides of the magnet 4.
Used as a kind of improved procedure, the magnet 4 is integrally formed with the camera lens carrier 5, i.e., the described outside of camera lens carrier 5
It is embedded in the magnet 4.
Used as a kind of improved procedure, the flexible coil piece 3 includes flexible substrate 31 and is formed in the flexible substrate 31
On multilayer cabling 32, the flexible coil piece 3 can be directly fitted on the inwall of the shell 1, corresponding with the magnet 4.Profit
With cabling 32 as the coil for producing torque, without winding again, directly fit, be easy to assembling.The flexible substrate 31 preferably but
It is not limited to FPC or PCB.Electrically connected with the mainboard in electronic equipment using FPC or PCB, by conducting resinl or can be welded to connect,
The spot welding structure of relatively existing coil is faster more stable.
The voice coil motor also includes base 7, and its assembling relative with the shell 1 is fixed.The base 7 is preferred but does not limit
It is set to square structure, a light hole 71 is provided with the middle of it, four angles is respectively arranged with fixed column 72 for being socketed the lower bullet
Piece 6, the edge of light hole 71 is provided with the first dust ring 73 of projection.Preferably, it is provided with the outside of the first dust ring 73
The second raised dust ring（Do not shown in figure）, an annular groove is formed between the first dust ring 73 and the second dust ring.Two
The design of dust ring increases the path that dust or foreign object enter camera by voice coil motor, and dust-proof effect is more excellent,
Base 7 is stronger to the positioning and resistance to tilting of carrier 5, solves the motor dust-proof effect of single dust ring in the prior art not
Obvious problem.
Voice coil motor after improvement is more convenient for assembling, and the assembling process of the voice coil motor is as follows：Stator is assembled：Upper bullet
Piece 2 is placed on 1 inner top of shell → dispensing → flexible coil piece 3 and is affixed on 1 inwall of shell → baking-curing；Mover is assembled：Magnet 4
Seat is carried with camera lens to assemble（This step can be exempted from if design is integrally formed）→ dispensing → load seat and lower shell fragment 6 assemble → solidify → point
Glue → assemble → solidify with base 7；Closing lid：The mover for assembling and stator relative makeup → dispensing → solidification.
This voice coil motor, that it changes the principle of existing spring-piece type voice coil motor, by the use of flexible coil piece 3 as voice coil loudspeaker voice coil horse
The stator for reaching, magnet 4 is powered as mover, flexible coil piece 3, produces the eternal magnetic field interaction in magnetic field and magnet 4, so that
Drive camera lens to move up and down, the structure and accessory of voice coil motor are simplified, while facilitating the assembling of motor.Magnet 4 as mover,
Mover easily is realized vibrating by external magnetic field interference, but mover no power, it is not necessary to mover is welded, it is easy to assembly.Flexible wires
Circle piece 3 need not be wrapped on carrier 5, can directly be fitted in the inwall of shell 1, and as stator without vibrating, good reliability, also just
It is electrically connected in the mainboard on electronic equipment.
Embodiment described above only expresses implementation method of the present utility model, and its description is more specific and detailed, but simultaneously
Therefore the limitation to the utility model the scope of the claims can not be interpreted as, as long as the institute in the form of equivalent or equivalent transformation
The technical scheme of acquisition, all should fall within protection domain of the present utility model.
