Obviously, the described embodiments are some embodiments of the present application, not all embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor are within the scope of protection of the present application.

In addition, the terms "first", "second" are only for the purpose of description, and cannot be understood as indicating or implying relative importance, or implicitly indicating the number of indicated technical features. Therefore, the features limited by "first", "second" can be explicitly or implicitly included one or more features. In the description of the utility model, unless otherwise specified, the meaning of "multiple" is two or more. In addition, the term "includes" and any variation thereof means "at least includes".

[0028] Please refer to Figure 1 And Figure 2 , Figure 1 The structural schematic view of the anti-shake motor base provided by an embodiment of the utility model; Figure 2 The explosion structural schematic view of the anti-shake motor base provided by an embodiment of the utility model.

[0029] To solve the technical problems of high manufacturing cost and low yield of the traditional embedded base, or to achieve at least one of the above advantages or other advantages, an embodiment of the utility model provides an anti-shake motor base 10. As shown in the figure, the anti-shake motor base 10 comprises a body 11, a circuit layer 12 and a plurality of welding holes 13.

[0030] The body 11 has opposite first and second surfaces 111 and 112. In specific implementation, the body 11 is injection molded, and since the body 11 does not embed the circuit layer 12, the body 11 can be directly molded by one-time injection molding. Similarly, since the circuit layer 12 is not embedded in the body 11, the thickness of the body 11 can be further thinned, thereby realizing the height reduction of the overall anti-shake motor, the thinning of the overall thickness of the finished product, and further miniaturization.

[0031] The traditional embedded base needs to cover the circuit layer 12 in the body 11, so the body 1 needs to have a certain thickness and cannot be thinned, resulting in the inability to reduce the height of the overall anti-shake motor.

[0032] The circuit layer 12 is arranged on the first surface 111 of the body 11. The circuit layer 12 is a metal circuit processed by stamping. In specific implementation, the first surface 111 is provided with a limiting groove 14. The circuit layer 12 is fixed in the limiting groove 14 by means of gluing or clamping. The limiting groove 14 can limit the circuit layer 12 to avoid deviation of the circuit layer 12, and facilitate reduction of the thickness of the overall anti-shake motor base 10.

[0033] In some embodiments, the anti-shake motor base 10 can further include a first IC 15 and a second IC 16. The first IC 15 and the second IC 16 are electrically connected with the circuit layer 12, respectively. In specific implementation, the first IC 15 and the second IC 16 are arranged on the first surface 111 of the body 11, and the first IC 15 and the second IC 16 are located below the circuit layer 12, thereby facilitating reduction of the overall thickness of the body 11.

[0034] Further, the circuit layer 12 has a plurality of first soldering points 121, a plurality of second soldering points 122, a plurality of third soldering points 123, and a pin 124. The plurality of first soldering points 121, the plurality of second soldering points 122, and the plurality of third soldering points 123 are used for soldering other components. The pin 124 can lead out the overall circuit of power supply and signal in the anti-shake motor base 10.

[0035] Preferably, the plurality of first soldering points 121, the plurality of second soldering points 122, and the plurality of third soldering points 123 are on the same horizontal plane. Such arrangement can reduce the stamping process required by the circuit layer 12 to some extent, simplify the process, reduce the manufacturing cost, and facilitate soldering and subsequent assembly.

[0036] It should be noted that, in the traditional embedded base, since the circuit layer 12 is embedded in the interior of the body 11, the circuit layer 12 needs to be stamped multiple times to lead the soldering points upward or downward to the outside of the body 11, so as to facilitate assembly and soldering of other components, which invisibly increases the difficulty and cost of the processing process.

[0037] On the basis of the above, as shown in Figure 3 the second surface 112 of the body 11 is provided with a plurality of soldering holes 13. The plurality of soldering holes 13 extend to the first surface 111 and expose the plurality of first soldering points 121, the plurality of second soldering points 122, and the plurality of third soldering points 123. In the specific assembly process, the first soldering points 121, the second soldering points 122, and the third soldering points 123 can be vertically soldered and assembled from the bottom of the body 11 upward through the soldering holes 13, thereby facilitating automatic soldering and improving the soldering yield, and avoiding material loss caused by soldering failure.

[0038] In some embodiments, as shown in Figure 4As shown, the utility model also provides a kind of anti-shake motor, include preceding anti-shake motor base 10, and OIS coil 20, OIS frame 30 and mirror seat 40.

[0039] OIS coil 20 is arranged on circuit layer 12 and is electrically connected with circuit layer 12.In implementation, OIS coil 20 includes two first coils 21 and two second coils 22.Two first coils 21 are oppositely arranged, and two second coils 22 are oppositely arranged.

[0040] As Figure 5 Two first coils 21 are electrically connected with circuit layer 12 and first IC 15 respectively by a plurality of first solder joints 121 and a plurality of second solder joints 122.First IC 15 can control and detect the magnetic field generated by the power supply of two first coils 21.

[0041] Two second coils 22 are electrically connected with circuit layer 12 and second IC 16 respectively by a plurality of first solder joints 121 and a plurality of second solder joints 122.Second IC 16 can control and detect the magnetic field generated by the power supply of two second coils 22.

[0042] OIS frame 30 is movably arranged on the side of OIS coil 20 away from circuit layer 12.In implementation, OIS frame 30 can move along X-axis direction and / or Y-axis direction relative to anti-shake motor base 10.A plurality of magnets 50 are arranged on OIS frame 30.A plurality of magnets 50 are distributed on the inner circumferential side of OIS frame 30.When two first coils 21 and / or two second coils 22 are powered, the magnetic field generated by the power supply acts on magnet 50, and then drives OIS frame to move along X-axis direction and / or Y-axis direction relative to anti-shake motor base 10, to realize anti-shake and improve imaging quality.

[0043] Mirror seat 40 is movably arranged in OIS frame 30.In implementation, mirror seat 40 can move along Z-axis direction relative to OIS frame 30. Figure 6 As shown, third coil 60 is arranged on mirror seat 40.Specifically, third coil 60 is a ring coil.Third coil 60 is sleeved on mirror seat 40, and third coil 60 is electrically connected with circuit layer 12.When third coil 60 is powered, the magnetic field generated by the power supply acts on magnet 50, and then drives mirror seat 40 to move along Z-axis direction relative to OIS frame 30, to realize focusing and zooming function, and improve imaging quality.

[0044] On the basis of the above, the anti-shake motor can further include a first elastic sheet 70, a second elastic sheet 80 and a suspension wire 90. In specific implementation, the first elastic sheet 70 is located between the OIS frame 30 and the OIS coil 20, and the first elastic sheet 70 is connected to the OIS frame 30 and the lens seat 40 respectively. The first elastic sheet 70 can provide a restoring force for the lens seat 40, and make the movement of the lens seat 40 more linear, which is beneficial to the normal implementation of the focusing and zooming functions.

[0045] The second elastic sheet 80 is arranged above the OIS frame 30. The second elastic sheet 80 is connected to the OIS frame 30 and the lens seat 40 respectively. The second elastic sheet 80 is electrically connected to the third coil 60. The second elastic sheet 80 can also provide a restoring force for the lens seat 40, and lead the power supply and signal line of the third coil 60 out to the second elastic sheet 80.

[0046] The suspension wire 90 is electrically connected to the third welding point 123 at one end and electrically connected to the second elastic sheet 80 at the other end, thereby realizing the electrical connection between the third coil 60 and the circuit layer 12.

[0047] In some embodiments, the anti-shake motor can further include an outer cover 100. The outer cover 100 covers the anti-shake motor base 10.

[0048] In summary, the anti-shake motor base and the anti-shake motor provided by the present application have the following advantages. Compared with the prior art, the circuit layer is designed to be not embedded, and the circuit layer is arranged on the first surface, which simplifies the manufacturing process and manufacturing cost of the body and the circuit layer, is beneficial to the miniaturization of the anti-shake motor, and is convenient for subsequent assembly and welding, thereby improving the yield of the product.
