[0102] The detailed features and advantages of the present application are described in the embodiments below, which are sufficient for any person skilled in the art to understand the technical contents of the present application and to implement the same, and any person skilled in the art can easily understand the related purposes and advantages of the present application according to the contents disclosed in the present specification, the scope of the patent application and the drawings. The following embodiments further illustrate the ideas of the present application, but do not limit the scope of the present application in any way.
[0103] The present application provides a reflecting module capable of achieving image stabilization, which comprises a reflecting element, a rotatable carrier, a fixed base, a spherical support structure, an auxiliary support structure and an image stabilization driver.
[0104] The reflective element has a reflecting surface for turning the optical path of the incident light, and the reflective element is arranged on a rotatable carrier. The reflective element can be, for example, a prism or a mirror, but the present application is not limited thereto. The fixed base is connected to the rotatable carrier by an elastic element. A spherical support structure is arranged between the rotatable carrier and the fixed base. An auxiliary support structure is arranged on at least one of the rotatable carrier and the fixed base, and the auxiliary support structure corresponds to the spherical support structure. An image stabilization driver is arranged at least partially on the rotatable carrier, and the image stabilization driver is used to drive the rotatable carrier to rotate about the spherical support structure as the rotation axis, so that the rotatable carrier can drive the reflective element to rotate. The rotatable carrier can rotate in a pitching and yawing manner. Please refer to Figure 33 , which shows a schematic view of the pitching DP and yawing DY of the rotatable carrier of the camera module 10 on the electronic device 8.
[0105] The reflective module disclosed in the present application can achieve image stabilization. The spherical support structure is used as the fulcrum to provide the freedom of rotation of the reflective element, thereby achieving the effect of image stabilization.
[0106] In an embodiment, the spherical support structure can be a sphere, and the spherical support structure and the auxiliary support structure can have at least three contact points. In this way, the spherical support structure and the auxiliary support structure are supported in a point contact manner, which can reduce the resistance during rotation and can prevent the rotation axis from being easily deviated. In addition, it is also helpful for the spherical support structure to be able to rotate at a small angle in a fixed position. The sphere can have two spherical surfaces respectively facing the rotatable carrier and the fixed base, and both of the two spherical surfaces can be supported by the auxiliary support structure. Please refer to Figure 34 , which shows a schematic view of the spherical support structure 155 supported by the spherical surface 1551 of the fixed base 151 and the auxiliary sphere 1561 of the auxiliary support structure 156, and the spherical support structure 155 supported by the spherical surface 1552 of the rotatable carrier 153 and the conical groove 1562 of the auxiliary support structure 156.
[0107] In an embodiment, the spherical support structure can include at least one spherical surface, the auxiliary support structure can include at least two convex surfaces, and the at least one spherical surface and the at least two convex surfaces can have at least two contact points. In this way, the spherical support structure is supported in a convex-to-convex manner, which can reduce the resistance during rotation and can prevent the rotation axis from being easily deviated. In addition, the convex-to-convex support can prevent the rotatable carrier and the fixed base from interfering with each other. Please refer to Figure 5 and Figure 23, wherein the fourth embodiment of the fixed base 451, the spherical support structure 455 and the auxiliary support structure 456 are shown, the spherical support structure 455 has two spheres 4553, the auxiliary support structure 456 has two auxiliary spheres 4561, and the two spheres 4553 of the spherical support structure 455 and the two auxiliary spheres 4561 of the auxiliary support structure 456 have two contact points. At least one spherical surface of the spherical support structure can be a sphere or a spherical protrusion. Please refer to Figure 24 and Figure 5 , respectively, show that at least one spherical surface of the spherical support structure 155 is a sphere and at least one spherical surface of the spherical support structure 555 is a spherical protrusion, but the present application is not limited to the type of spherical support structure.
[0108] In one embodiment, the spherical support structure can include at least one spherical surface, and the at least one spherical surface and the auxiliary support structure can have at least three contact points. In this way, the point contact between the spherical support structure and the auxiliary support structure can reduce the resistance during rotation and can make the rotation axis less likely to deviate, in addition, it also helps the spherical support structure to rotate at a small angle in a fixed position. At least one spherical surface of the spherical support structure can be a sphere or a spherical protrusion, but the present application is not limited thereto.
[0109] The elastic element can provide a preload force to the rotatable carrier, and the preload force can exert a force in the direction of the fixed base to support the rotatable carrier through the spherical support structure located between the fixed base and the rotatable carrier; in this way, the rotatable carrier can be assembled to the spherical support structure. Wherein, the elastic element can be arranged around the spherical support structure; in this way, the spherical support structure can be less likely to be damaged by a more balanced pre-pressing method. The vertical angle between two elements (such as lines and lines, surfaces and surfaces, or lines and surfaces) described in the present application is 90 degrees or close to 90 degrees.
[0110] The image stabilization driver can include at least one drive magnet and at least one drive coil, wherein one of the drive magnet and the drive coil is arranged on the rotatable carrier, and the other is arranged on the fixed base; in this way, the rotatable carrier can be provided with a rotating force. Wherein, the drive magnet and the drive coil can be arranged facing each other in a direction perpendicular to the reflecting surface; in this way, it is helpful to form a more efficient space configuration to achieve miniaturization. Wherein, the number of drive magnets can be at least two, and the number of drive coils can be at least two; in this way, at least two axial rotating forces can be provided. In the embodiment where the number of drive magnets is at least two, the reflecting module can further include at least two position sensing elements, and the position sensing elements and the drive magnets can be arranged facing each other in a direction perpendicular to the reflecting surface. In this way, the position sensing elements can be used to detect the position of the rotatable carrier.
[0111] The image-stable reflection module of the present application can further include a circuit board, wherein one of the circuit board and the driving magnet is disposed on the rotatable carrier, and the other is disposed on the fixed base, and the driving coil is disposed on the circuit board. Thus, the driving current can be provided to the driving coil by the circuit board.
[0112] The radius of curvature of the spherical support structure is R, and the shortest distance between the spherical support structure and the reflection surface is D, which can satisfy the following condition: 0.3 < R / D < 12; thus, a sufficient rotation angle and a preferable rotation stability ratio range can be obtained. Wherein, the following condition can also be satisfied: 0.5 < R / D < 10; thus, a preferable rotation stability ratio range can be obtained. Please refer to Figure 25 , which shows a schematic diagram of parameters R and D in the first embodiment of the present application.
[0113] In the image-stable reflection module of the present application, the spherical support structure and the fixed base can not have relative movement. Thus, the assembly of the spherical support structure is more efficient.
[0114] The type of the auxiliary support structure can be a sphere, a spherical protrusion, or a conical groove, and the present application is not limited thereto. In an embodiment, the auxiliary support structure can include at least two auxiliary spheres for supporting the spherical support structure, and the at least two auxiliary spheres have the at least two convex surfaces; thus, the contact of the auxiliary spheres can more effectively reduce the resistance of the spherical support structure. Wherein, the auxiliary support structure can also include at least three auxiliary spheres. In an embodiment, the auxiliary support structure can include at least two spherical protrusions for supporting the spherical support structure, and the at least two spherical protrusions have the at least two convex surfaces; thus, the design of the spherical protrusions can reduce the manufacturing cost while achieving the effect of reducing resistance. Wherein, the auxiliary support structure can also include at least three spherical protrusions. In an embodiment, the auxiliary support structure can include a conical groove for supporting the spherical support structure; thus, the design of the conical groove can improve the manufacturing efficiency and the structural stability of the spherical support structure. Wherein, the conical groove can be a triangular pyramid or a quadrangular pyramid shape, which has multiple surfaces, but the present application is not limited thereto.
[0115] The spherical support structure can be a ferromagnetic material to be adsorbed on the rotatable carrier or the fixed base by magnetic force. Thus, the assembly stability of the spherical support structure can be improved.
[0116] The reflective element can be a plastic prism made by injection molding. In this way, the manufacturability of the plastic prism is provided to improve the production capacity of the reflective element. The reflective element can further have an entrance surface and an exit surface. The entrance surface and the reflective surface are arranged corresponding to each other in the light incident direction, and the exit surface and the reflective surface are arranged corresponding to each other in the light exit direction, so that the light sequentially passes through the entrance surface, the reflective surface and the exit surface along the optical path from the object side to the image side. At least one of the entrance surface and the exit surface can have an optical aspheric surface, so that the reflective element can have light refraction power. In this way, better optical resolution can be provided.
[0117] The present application provides a camera module, which includes the aforementioned reflective module, an imaging lens module and an electronic photosensitive element. The reflective module is arranged on the object side of the imaging lens module, and the electronic photosensitive element is arranged on the imaging surface of the imaging lens module. The reflective module is used to stabilize the image signal captured by the electronic photosensitive element.
[0118] In the reflective module disclosed by the present application, the reflective element can further have an embedding structure surrounding the reflective surface, and the reflective element can be engaged with the rotatable carrier through the embedding structure. In this way, the assembly tolerance of the reflective element can be reduced, so that the geometric center of the reflective element is aligned with the rotation axis, and the optical imaging quality is maintained. The embedding structure is used to align the geometric center of the reflective surface with the center of the spherical support structure, so that the exit surface of the reflective element is coaxially aligned with the optical axis of the imaging lens module.
[0119] The camera module disclosed by the present application can further include an autofocus driver, which is at least partially arranged in the imaging lens module, and the autofocus driver is used to drive the imaging lens module to move in the direction parallel to the optical axis thereof.
[0120] The technical features of the reflective module disclosed by the present application can be combined to achieve the corresponding effects.
