For better use of the present embodiment, the first elastic arm 3 is provided with a circular ring portion 5 to disperse the stress of the elastic arm 2.
The first elastic arm 3 has a plurality of curved portions, and in general, the curved portions have a substantially semicircular structure, and the circular arc of the circular ring portion 5 is larger than a semicircle, and in this case, the radial length is relatively long, so that the force distribution can be well realized for the entire first elastic arm 3.
For better use of the present embodiment, any one of the resilient arms 2 is connected to the attachment ring 1 by a second resilient arm 6.
The second elastic arm 6 is of an elongated structure, and the first elastic arm 3 is also of an elongated structure, so that in different embodiments, the purpose of changing the stiffness coefficient can be achieved by adjusting the thickness, the length and the like of the elastic arm, and thus the device is suitable for different use requirements. Obviously, the plane of the second elastic arm 6 is the same as the plane of the connecting ring 1.
For better use of the present embodiment, any one of the elastic arms 2 further comprises a first positioning element 7 and a second positioning element 8; the first positioning piece 7 is provided with a first positioning hole, one end of the first positioning piece 7 is connected with one end of the first elastic arm 3, and the other end of the first positioning piece 7 is connected with the connecting ring 1; the second positioning piece 8 is provided with a second positioning hole, and the second positioning piece 8 is connected with one end of the first elastic arm 3 far away from the first positioning piece 7.
The first positioning piece 7 and the second positioning piece 8 can be used for realizing connection between the elastic support arm 2 and other components of the motor, so that fixed constraint is formed on the whole structure, and meanwhile, the assembly precision and the connection stability are well guaranteed.
As shown in fig. 2 and 3, this embodiment also discloses an OIS motor based on a dome structure 400 as described above.
In this embodiment, the number of the elastic arms 2 is four, and the four elastic arms 2 are uniformly arranged on the outer side of the connecting ring 1, so as to provide a good deformation force required in the Z direction.
In this embodiment, the device further comprises a carrier assembly 200 and a bracket assembly 300, wherein the carrier assembly 200 is connected with the connecting ring 1 through an adhesive; the bracket assembly 300 is connected with the elastic support arm 2, and the bracket assembly 300 is provided with a limiting structure to limit the movement stroke of the bracket assembly 300.
The OIS motor further comprises a base assembly 500 and a housing assembly 100, the base assembly 500 is connected with the housing assembly 100, and the carrier assembly 200, the bracket assembly 300 and the elastic sheet are mutually matched and arranged between the base assembly 500 and the housing assembly 100. In this embodiment, the second positioning member 8 is connected to the base assembly 500, and the first positioning member 7 is connected to the bracket assembly 300, and since the first positioning member 7 has a first positioning hole and the second positioning member 8 has a second positioning hole, the base assembly 500 and the bracket assembly 300 have a second positioning post and a first positioning post that are respectively engaged with the second positioning member 8 and the first positioning member 7. On this basis, the connection ring 1 is bonded to the carrier assembly 200, thereby achieving assembly of the carrier assembly 200, the base assembly 500 and the bracket assembly 300 through the dome structure 400.
After the assembly is completed, the four first elastic arms 3 are positioned at the four top corners of the motor, so that each first elastic arm 3 deforms up and down, deforms left and right and deforms front and back at the position where the first elastic arm is positioned, and the anti-shake requirement of the motor is met.
The limiting structure comprises a first limiting structure 9 arranged on the upper side of the bracket assembly 300 and a second limiting structure 10 arranged on the lower side of the bracket assembly 300; the first limiting structure 9 is a rib formed around the outer edge of the bracket assembly 300, and the rib is matched with the inner side of the housing assembly 100 to limit in the Z direction; the second limiting structure 10 is a protruding block extending toward the lower side of the bracket assembly 300, and the base assembly 500 has a clamping portion 11 engaged with the protruding block, so that the limiting of the bracket assembly 300 can be achieved in the X direction and the Y direction through the protruding block and the clamping portion 11.
Thus, in use of the present embodiment, the second positioning member 8 is coupled to the base assembly 500, and the entire structure acts as a fixed constraint at the second positioning member 8. The connecting ring 1 is connected with the carrier assembly 200, after the structure is electrified, a force in the Z direction is applied to the carrier assembly 200, so that the carrier assembly 200 moves along the vertical direction, the displacement of the carrier assembly 200 is controlled through the second elastic arm 6, the carrier assembly 200 has the capability of moving vertically, and the moving distance of the carrier assembly 200 can be controlled through the change of the size of the second elastic arm 6. When the support assembly 300 is connected with the spring plate structure 400 through the first positioning member 7 and applies a force in the vertical direction to the carrier assembly 200, the support assembly 300 is subjected to a reaction force due to the fact that the carrier assembly 200 is stressed by the support assembly 300, so that the support assembly 300 is driven to move in the vertical direction through the spring plate structure 400, and the vertical displacement of the support assembly 300 can be limited due to the fact that the first limiting structure 9 is arranged on the support assembly 300, namely the stroke of the support assembly 300 is limited according to practical situations, so that the spring plate structure 400 can better exert the effect of the spring plate structure. It can be seen that, when the force applied to the bracket assembly 300 comes from the base assembly 500, the force applies electromagnetic force in the plane direction of the base assembly, that is, electromagnetic force is applied in the plane of the X direction and the Y direction, so that the bracket assembly 300 has plane movement capability, and the bracket assembly 300 is limited by the second limiting structure 10, so that the displacement adjustment of the plane of the X direction and the Y direction can be well realized through the first elastic arm 3.
Thus, by providing the dome structure 400 of the present embodiment on the OIS motor, the OIS motor as a whole can be provided with a displacement with multiple degrees of freedom, thereby achieving the required functional requirements.
The foregoing is merely a preferred embodiment of the present utility model, and it should be noted that the above-mentioned preferred embodiment should not be construed as limiting the utility model, and the scope of the utility model should be defined by the appended claims. It will be apparent to those skilled in the art that various modifications and adaptations can be made without departing from the spirit and scope of the utility model, and such modifications and adaptations are intended to be comprehended within the scope of the utility model.
