It should be understood that the specific embodiments described herein are merely illustrative of the present application and are not intended to limit the present application.
With the increasing demands for high accuracy and high magnification of the camera module, there is an increasing demand for a compensation performance of an optical anti-shake (OIS) function for compensating for shake, vibration, and the like of the camera module of an electronic device such as a smartphone.
In the related art, in the case where an OIS driver is added to an OIS driver using a VCM or the like, the optical anti-shake structure inevitably increases the external dimensions, thickness dimensions, and the like of a camera module by a large amount, but the module height of the camera module is required to be lower and lower along with the development of a periscopic camera module, so that the requirement on the optical anti-shake structure thickness of the camera module is also more and more strict. Therefore, how to achieve the optical anti-shake effect of the camera module and reduce the height of the camera module has become an urgent problem to be solved.
In order to solve the above technical problem, please refer to fig. 1 to 3, a first aspect of the present application provides an anti-shake driving apparatus, which can reduce a module height of a camera module while achieving optical anti-shake of the camera module.

The lens supporting frame 110 is provided with at least one lens 115 located in the through hole 114, that is, the through hole 114 is a space of the lens supporting frame 110 for accommodating the lens 115, and at least one lens 115 is disposed in the through hole 114, for example, the number of the lenses 115 may be one, two, three or more. It should be noted that, the more the lenses 115 are, the better the lens 115 is, since the lens 115 itself has a weight, and the weight of the lens 115 is accumulated on the lens supporting frame 110, and the anti-shake driving apparatus 100 needs to overcome the weight of the lens 115 to drive the lens supporting frame 110 to move, the number of the lenses 115 in the through hole 114 also determines the optical anti-shake performance of the anti-shake driving apparatus 100 to some extent, for example, the anti-shake performance of the anti-shake driving apparatus 100 when the number of the lenses 115 is one may be beneficial to the optical anti-shake performance of the anti-shake driving apparatus 100 when the number of the lenses 115 is two.
Referring to fig. 2-3, the shake support frame 120 is used as a carrier for carrying other components in the anti-shake driving apparatus 100, the shake support frame 120 is disposed outside the lens support frame 110 and spaced from the lens support frame 110, that is, the shake support frame 120 is annular and disposed outside the lens support frame 110, and the inner annular wall surface of the shake support frame 120 is spaced from the outer peripheral wall surface of the lens support frame 110, where the size of the space needs to be designed by a designer according to the offset of the lens support frame 110. Specifically, the shake support frame 120 is a rectangular ring structure, the shake support frame 120 has a first outer side surface 121 and a second outer side surface 122 which are arranged oppositely, and further has a third outer side surface 123 and a fourth outer side surface 124 which are arranged oppositely, the first outer side surface 121 and the second outer side surface 122 are the same in shape and size and are both rectangular surfaces, the third outer side surface 123 and the fourth outer side surface 124 are the same in shape and size and are both rectangular surfaces, and the first outer side surface 121, the second outer side surface 122, the third outer side surface 123 and the fourth outer side surface 124 are connected in a closed end manner to enclose an inner ring wall surface which forms the shake support frame 120.
Further, the first outer side surface 121 is disposed adjacent to the first hole wall surface 1141, and the second outer side surface 122 is disposed adjacent to the second hole wall surface 1142, that is, after the shake support frame 120 is sleeved on the lens support frame 110, in a direction along the first outer side surface 121 and pointing to the second outer side surface 122 (i.e., a direction perpendicular to the first outer side surface 121), a distance between the first outer side surface 121 and the first hole wall surface 1141, and a distance between the second outer side surface 122 and the second hole wall surface 1142 (as a dimension H in fig. 1) are smaller than, in a direction along the third outer side surface 123 and pointing to the fourth outer side surface 124 (i.e., a direction parallel to the first outer side surface 121), a distance between the third outer side surface 123 and the third hole wall surface 1143, and a distance between the fourth outer side surface 124 and the fourth hole wall surface 1144 (as a dimension D in fig. 1), where the dimension H < the dimension D.
The elastic connecting assembly 130 is used as a part for connecting the lens supporting frame 110 and the shaking supporting frame 120 in the anti-shaking driving device 100, the elastic connecting assembly 130 is located at two sides of the lens supporting frame 110, and is connected between the lens supporting frame 110 and the shaking supporting frame 120, specifically, the elastic connection members 130 are located between the third outer side surface 123 and the third hole wall surface 1143, and between the fourth outer side surface 124 and the fourth hole wall surface 1144, the elastic connecting elements 130 are disposed on two sides of the lens supporting frame 110 along the direction from the third outer side 123 to the fourth outer side 124, and are connected to the lens supporting frame 110 and the shake supporting frame 120, in other words, the two sides of the lens supporting frame 110 suspended in the shake supporting frame 120 are connected to the shake supporting frame 120 through the elastic connecting elements 130.
In summary, the first outer side 121 of the shake support frame 120 is disposed adjacent to the first hole wall 1141 of the through hole 114, and the second outer side 122 is disposed adjacent to the second hole wall 1142, the elastic connection assembly 130 is disposed on two sides of the lens support frame 110 along the direction from the third outer side 123 to the fourth outer side 124 of the shake support frame 120, so as to effectively reduce the dimension of the anti-shake driving apparatus 100 along the direction from the first outer side 121 to the second outer side 122 of the shake support frame 120, thereby achieving the purpose of reducing the height of the camera module.
It can be understood that the lens supporting frame 110 is spaced apart from the shaking supporting frame 120 and connected to the shaking supporting frame 120 by the elastic connecting component 130, that is, to realize the movement of the lens supporting frame 110, the elastic connecting component 130 directly connected to the lens supporting frame needs to be used, so in this embodiment, the elastic connecting component 130 includes at least two electrically controlled elastic members 134.
Referring to fig. 3, the electrically controlled elastic element 134 is a component capable of generating elastic deformation, for example, the elastic deformation of the electrically controlled elastic element 134 can be realized by turning on or off the electrically controlled elastic element 134.
Specifically, the electrically controlled elastic member 134 is a shape memory alloy elastic portion (SMA elastic portion for short) having a predetermined shape in the power-on mode and an initial shape in the power-off mode. The above-mentioned power-on mode should be understood as a certain voltage or a certain current that can trigger the electrically controlled elastic element 134 to deform; the power-off mode may be understood as a certain voltage or a certain current that cannot trigger the electrically controlled elastic element 134 to deform, and of course, the value of the voltage or the current may be zero; the predetermined shape is the deformed shape of the electrically controlled resilient member 134 extending from its original shape along its length. That is, when the electrically controlled elastic member 134 is in the above-mentioned energization mode, the electrically controlled elastic member 134 is deformed from the initial shape to the predetermined shape (memory shape), and when the electrically controlled elastic member 134 is in the above-mentioned deenergized state, the electrically controlled elastic member 134 is deformed from the predetermined shape back to the initial shape.
It can be understood that there is uncertainty in the shake direction of the camera module, for example, in the plane perpendicular to the optical axis of the lens 115, the camera module may shake in the positive direction parallel to the X axis, may shake in the positive direction parallel to the Y axis, may shake in both the positive direction parallel to the X axis and the positive direction parallel to the Y axis, and of course, regardless of the shake direction of the camera module, the anti-shake driving apparatus 100 can at least eliminate the shake of the camera module in a certain direction, so in this embodiment, the at least one electrically controlled elastic element 134 is configured to deform during the power-on mode to drive the lens supporting frame 110 to drive the at least one lens 115 to move. For example, a single electrically controlled elastic element 134 may be in the above-mentioned power-on mode, and the electrically controlled elastic element 134 deforms to drive the lens supporting frame 110 to drive the at least one lens 115 to move in a single direction to implement the shake compensation; or a plurality (two or more) of the electrically controlled elastic members 134 may be in the above-mentioned power-on mode at the same time, and the electrically controlled elastic members 134 deform at the same time and drive the lens supporting frame 110 through a resultant force to drive the at least one lens 115 to face a single direction to implement the shake compensation; alternatively, the plurality of electrically controlled elastic members 134 are not simultaneously in the above-mentioned power-on mode and respectively generate deformation to drive the lens supporting frame 110 to drive the at least one lens 115 to move in at least two different directions, so as to implement the shake compensation.
