In order to achieve the above objectives, the technical solution adopted in the utility model is: a kind of stabilization autofocus motor, including outer The shell and pedestal of side airtight connection further include internal stator module, mover assembly, AF component and OIS component；

Stator module includes bracket and magnetite, and magnetite is arranged in four ends of bracket；

Mover assembly includes AF coil, carrier and upper elastic slice, and AF coil is directly wound on carrier, and carrier is fixed with bracket, on Elastic slice is connect with bracket；

AF component includes that stator module, mover assembly and lower elastic slice, lower elastic slice side are fixed with carrier, and side and pedestal are solid It is fixed；

OIS component includes soft board, OIS coil and pedestal, and OIS coil is set on the base, and its upside is soft board.

Further, lower elastic slice is equipped with three-dimensional bending section.

Further, three-dimensional bending section bending angle is 0-90 °.

Further, Hall element is additionally provided on soft board；

Further, Pin1 and Pin6 control motor Z-direction is mobile on soft board, and it is mobile that Pin2-5 controls motor X, Y-direction；

Further, Pin1-8 is the connection terminal of Hall element, and Pin9,14 control motor Z-directions are mobile, Pin10-13 It is mobile to control motor X, Y-direction.

In conclusion the utility model has following advantages:

The lower elastic slice of the part AF is fixed on the part OIS by the utility model, and centre uses bending technique, and lower elastic slice is rolled over Curved fixation, so that a piece of lower spring, not merely there is the function of spring under AF, there are also the function of the suspension of OIS, while bending Partial elastic coefficient adjustment is convenient, can effectively solve the problem that the higher problem of OIS motor height.

Specific embodiment

The utility model is further described with reference to the accompanying drawings and embodiments:

Embodiment 1:

A kind of stabilization autofocus motor, as depicted in figs. 1 and 2, shell 1 and pedestal 2 including outside airtight connection, also Including internal stator module, mover assembly, AF component and OIS component.

Specifically, stator module includes bracket 3 and magnetite 4, four ends of bracket 3 are arranged in magnetite 4, and magnetite 4 is specific For generating magnetic field.

With continued reference to attached drawing 1 and in conjunction with attached drawing 2, mover assembly includes AF coil 5, carrier 6 and upper elastic slice 7, wherein AF line Circle 5 is directly wound on carrier 6, and carrier 6 and bracket 3 are fixed, and upper elastic slice 7 is connect with bracket 3；

And AF component includes stator module, mover assembly and lower elastic slice 8, OIS component includes soft board 9, OIS coil 10 and bottom 2, OIS of seat coil 10 is arranged on pedestal 2, and its upside is soft board 9.

Wherein, lower 8 side of elastic slice and carrier 6 are fixed, and side and pedestal 2 are fixed, so, the lower elastic slice of the part AF is fixed on On the part OIS, meanwhile, as shown in figure 5, lower elastic slice 8 is equipped with three-dimensional bending section 71, which is 0- 90 °, preferably 90 ° in the present embodiment, so a piece of lower spring, not merely there is the function of spring under AF, there are also OIS's The function of suspension, while dogleg section coefficient of elasticity is easy to adjust, can effectively solve the problem that the higher problem of OIS motor height.

When focusing motor is open loop type motor, motor is perceived using gyroscope on mobile phone, and signal passes to OIS coil, Specifically, referring to attached drawing 3 and combining subordinate list 1, Pin1,6 control motor Z-directions are mobile, and Pin2-5 controls motor X, Y-direction is moved Dynamic, Pin foot positive and negative anodes are powered, so that the magnetic field force induced effect of hot-wire coil, it is mobile to drive camera lens, and especially by electrical current Size controls the mobile distance of camera lens.
