Specific embodiment
For it is relatively intuitive, be fully understood by technical solution of the present invention, now just combine attached drawing of the present invention to carry out non-limiting
Feature description it is as follows:
As Figure 1-Figure 5, a kind of moving-magnetic type device for driving optical lens is connect including shell 1 and with shell 1
Pedestal 2, shell 1 is interior to be equipped with carrier 3, and 3 upper and lower ends of carrier are respectively equipped with upper reed plate 4 and lower reed 5, and the quadrangle of carrier 3 is all provided with
There is a magnetite 6,2 four jiaos of pedestal are equipped with the printed circuit board coils 7 positioned at 6 outside of magnetite, on each printed circuit board coil 7
Equipped with Hall element 8.
The quadrangle of lower reed 5 is connect with pedestal 2, and pedestal 2 is assembled with camera (not shown).The four of lower reed 5
Angle is equipped with fixinig plate 51, and fixation hole 511 is equipped on each fixinig plate 51, and the quadrangle of pedestal 2 is equipped with convex block 21, fixation hole 511
It is caught in for convex block 21.
Gasket 9 is equipped in shell 1, gasket 9 is connect with upper reed plate 4, and gasket 9 plays the role of precompressed upper reed plate 4.
Carrier 3 in order to facilitate the installation of, the quadrangle of carrier 3 are all provided with fluted 31, and magnetite 6 is fixed in groove 31, and magnetite 6
