Traditional micro drives motor generally comprises loam cake, Upper gasket, upper spring sheet, lens carrier, magnetite assembly, coil block, lower gasket, lower spring chip module and base; Secondly this kind structure is higher to the requirement of upper spring sheet and lower spring chip module, at first requires the spring inner ring to have good anti-deformation nature at horizontal plane, wants suitably at the elastic force that axially provides vertical with horizontal direction, and is too small and cross mostly bad; Excessive, the electromagnetic force that produces between coil block and the magnetite assembly can not be pushed to it suitable position, affects the stroke of motor; The too small stability that then can affect motor, slight electromagnetic force or the gravity of miscellaneous part and acceleration force all can produce certain impact to motor, affect the smooth working of motor.
Summary of the invention
The purpose of this invention is to provide the spring that is used for the micro drives motor that a kind of structure is comparatively reasonable, performance is comparatively good.
The technical scheme that realizes the object of the invention is: a kind of spring for the micro drives motor comprises four silk springs of outer ring, inner ring and connection outer ring and inner ring; The basic configuration of described outer ring is square, comprises four straight lines and the triangle enhancing section that is positioned at adjacent two the folded interior angle of straight line places; Described inner ring comprises annular edge; The terminal that links to each other with inner ring that the second elastic portion of the first elastic portion with a plurality of U-shaped zigzag parts that described each spring comprises the top that links to each other with the outer ring, extend to form from the end at top, the arc shaped that extends to form from the end of the first elastic portion and the end from the second elastic portion extend to form; Described each U-shaped zigzag part comprises two straight flanges that be arranged in parallel and is connected a bent limit that connects these two straight flanges that each straight flange is the 0-20 degree with the angle of the straight line that links to each other with this spring top.
In the technique scheme, also be provided with a triangle reinforcement plate on described each straight line, one end of this triangle reinforcement plate links to each other with this straight line, the other end links to each other with the silk spring top that links to each other with this straight line, the 3rd end as the inner side edge of this triangle reinforcement plate along and parallel with the straight flange of each U-shaped zigzag part in this spring.
In the technique scheme, the inner side edge of described inner ring is along being provided with a plurality of appearance glue breach.
In the technique scheme, place, the folded exterior angle of two straight lines adjacent on the outer ring is provided with vee.
In the technique scheme, the terminal of each spring is perpendicular to a straight line that is adjacent, and arranges over against the center of this straight line, and this straight line is in abutting connection with the straight line that links to each other with this spring top.
The present invention is because employing has the shape of innovation, thereby make the spring inner ring have good anti-deformation nature at horizontal plane, guarantee the skew that the spring inner ring can the occurred level direction when the axis direction motion vertical with horizontal plane, and the spring inner ring is provided comparatively steadily and the suitable elastic force of dynamics at the axial direction vertical with horizontal plane.
