In the case of electric current, carrier can along Z axis free movement, when mobile phone fall or motion process in, carrier can produce motion simultaneously
Collided with base.Carrier and the material used in base are plastic cement material at present, and collision frequency excessively has chip generation,
Chip caused by collision can be directly entered module internal and fall on IR upper surfaces, or even can fall into sensor upper table by naughty groove
Face, cause module imaging dirty bad.
Utility model content
For above-mentioned deficiency, technical problem to be solved in the utility model is：A kind of voice coil motor is provided, the voice coil loudspeaker voice coil horse
Up to the generation that can effectively prevent motor carrier and base friction chip, the dust-proof work(of voice coil motor is realized to a certain extent
Energy.
In order to solve the above technical problems, the technical solution adopted in the utility model is：
A kind of voice coil motor, including base and carrier, the base are provided with boss, the load close to the surface of the carrier
Body contacts with the boss, it is characterised in that the boss surface is provided with multiple first sheet metals, the carrier with it is the multiple
First sheet metal corresponding position is provided with multiple second sheet metals, and the multiple first sheet metal flushes, the multiple second gold medal
Category piece flushes.
Preferably, the multiple first sheet metal is higher than set boss surface, institute corresponding with multiple first sheet metals
Stating multiple second sheet metals can be higher than or maintain an equal level or less than carrier surface.
Preferably, the multiple first sheet metal maintains an equal level or less than set boss surface, with multiple first metals
Piece is corresponding, and the multiple second sheet metal is higher than carrier surface.
Preferably, first sheet metal and the second sheet metal are embedded into the base boss and described by injection respectively
Carrier.
Preferably, the surface configuration of first sheet metal and the second sheet metal is identical.
Preferably, the size of first sheet metal is less than the size of the second sheet metal.
Preferably, the size of first sheet metal is more than the size of the second sheet metal.
Due to voice coil motor of the present utility model, sheet metal is designed with motor base boss and carrier so that in horse
Up to it is upper electric when effectively prevent due to fall wait caused by base and carrier rub the generation of chip so that voice coil motor is one
Determine that there is dust reduction capability in degree.

Embodiment
In order that the purpose of this utility model, technical scheme and advantage are more clearly understood, below in conjunction with accompanying drawing and implementation
Example, the utility model is further elaborated.It should be appreciated that specific embodiment described herein is only explaining
The utility model, it is not used to limit the utility model.
Embodiment one：
As shown in figs. 1A-1 c, a kind of voice coil motor, including base 11 and carrier 14, the table that base 11 contacts with carrier 14
Face is provided with boss 12, and the surface of boss 12 is provided with four sheet metals 13, and the height of four sheet metals 13 flushes, carrier 14 and sheet metal
13 corresponding positions are provided with four sheet metals 15, and the height of four sheet metals 15 flushes, and sheet metal 13 is higher than the surface of boss 12, gold
The surface of category piece 15 maintains an equal level with the lower surface of carrier 14, motor not on it is electric when, due to the base and carrier of reason voice coil loudspeaker voice coil such as falling
Collision become the collision of sheet metal 13 and sheet metal 15 because sheet metal 3 is higher than boss, which prevent base and carrier
Collision between plastic material, it is effectively prevented because of the generation of chip caused by collision.
Sheet metal 13 and the surface of sheet metal 15 are all rectangle in the present embodiment, and the area of metal 13 is less than sheet metal 15
Area, sheet metal 13 and sheet metal 15 are embedded into base boss 12 and the surface of carrier 14 by injection respectively, can be direct during assembling
Both are assembled.The material of sheet metal and quantity can determine according to factors such as motor weight in practical application.
