[0112] The present application is further explained in the following embodiments in detail, which are sufficient to understand the technical content of the present application and to implement the present application by any person skilled in the art, and according to the content disclosed in the present specification, the scope of the patent application and the drawings, any person skilled in the art can easily understand the related purposes and advantages of the present application. The following embodiments further illustrate the concepts of the present application, but do not limit the scope of the present application in any way.

[0113] The present application provides an imaging lens driving module, which includes an imaging lens, a lens carrier and a base. The imaging lens has an optical axis. The lens carrier mounts the imaging lens. The base is correspondingly arranged with the lens carrier.

[0114] The lens carrier includes a first guiding rail and a second guiding rail. The base includes a third guiding rail and a fourth guiding rail.

[0115] The first guiding rail extends along a direction parallel to the optical axis. The first guiding rail has a first surface and a second surface. The first surface and the second surface are connected to each other, and the first surface and the second surface have an included angle therebetween. The included angle between the first surface and the second surface can be a dihedral angle.

[0116] The second guiding rail extends along a direction parallel to the optical axis. The second guiding rail has a third surface and a fourth surface. The third surface and the fourth surface are connected to each other, and the third surface and the fourth surface have an included angle therebetween. The included angle between the third surface and the fourth surface can be a dihedral angle.

[0117] The third guiding rail extends along a direction parallel to the optical axis. The third guiding rail has a fifth surface and a sixth surface. The fifth surface and the sixth surface are connected to each other, and the fifth surface and the sixth surface have an included angle therebetween. The included angle between the fifth surface and the sixth surface can be a dihedral angle.

[0118] The fourth guiding rail extends along a direction parallel to the optical axis. The fourth guiding rail has a seventh surface and an eighth surface. The seventh surface and the eighth surface are connected to each other, and the seventh surface and the eighth surface have an included angle therebetween. The included angle between the seventh surface and the eighth surface can be a dihedral angle.

[0119] The first guiding rail and the third guiding rail are correspondingly arranged. The first guiding rail and the third guiding rail can be correspondingly arranged in the appearance of an "∠ shape" corresponding to an "∠ shape", an "∩ shape" corresponding to an "∩ shape", or a "∟ shape" corresponding to a "∟ shape", but the present application is not limited thereto. The first guiding rail and the third guiding rail can be correspondingly arranged in the appearance of an "∠ shape" corresponding to an "∠ shape", an "∩ shape" corresponding to an "∩ shape", or a "∟ shape" corresponding to a "∟ shape", but the present application is not limited thereto.

[0120] ​The second guide rail and the fourth guide rail are set correspondingly. Among them, the second guide rail and the fourth guide rail can be set in a "∠ shape" corresponding to a "∠ shape" in appearance. "Shape" corresponds to " The setting of "shape" or "∟shape" corresponds to the setting of "∟shape", but the present invention is not limited to this.

[0121] The “∠ shape” of the guide rail can be understood as the angle between the two surfaces of the guide rail is an acute angle. The “∟ shape” of the guide rail can be understood as the angle between the two surfaces of the guide rail is an obtuse angle, and the “∟ shape” of the guide rail can be understood as the angle between the two surfaces of the guide rail is a right angle.

[0122] The imaging lens drive module provided by the present invention further includes a plurality of spheres disposed between the lens carrier and the base. The spheres provide the lens carrier with the freedom to translate relative to the base in a direction parallel to the optical axis.

[0123] The spheres include at least one first sphere and at least one second sphere. The at least one first sphere is disposed between the first guide track and the third guide track. The at least one second sphere is disposed between the second guide track and the fourth guide track.

[0124] Each of the first through eighth surfaces physically contacts the corresponding sphere at only one contact point. Alternatively, it can be understood as a single guide rail making two-point contact with a single sphere. This ensures the sphere's linear motion along a direction parallel to the optical axis. However, the present invention is not limited to this.

[0125] The imaging lens drive module provided by the present invention further includes a drive unit. The drive unit includes at least one magnet and at least one coil. The at least one magnet is disposed corresponding to the at least one coil, and one of the at least one magnet and the at least one coil is coupled to the lens carrier. When the at least one magnet is coupled to the lens carrier, it can be understood as a moving magnet drive configuration. When the at least one coil is coupled to the lens carrier, it can be understood as a moving coil drive configuration.

[0126] The drive unit is used to drive the lens carrier to move relative to the base in a direction parallel to the optical axis. By setting up two-point contact between each guide rail and a single sphere, the lens carrier can be moved relative to the base along the guide rail when driven by the drive unit.

[0127] According to the above-mentioned imaging lens driving module of the present application, by properly arranging the contact points between each of the first to eighth surfaces and the ball, the balance of the radial force in the direction perpendicular to the optical axis can be achieved, so that the lens carrier and the base have the function of mutual alignment. Moreover, by the guide tracks, the stability of the imaging lens during the automatic focusing movement can be ensured, thereby improving the imaging quality.

[0128] Further, the number of the at least one first ball can be at least two. By properly arranging the number of the first ball, the stability of the imaging lens during the automatic focusing movement can be improved. Further, the number of the at least one second ball can be at least two. By properly arranging the number of the second ball, the stability of the imaging lens during the automatic focusing movement can be improved. Alternatively, the number of the at least one second ball can be only one. By properly arranging the number of the second ball, the driving efficiency of the imaging lens driving module can be optimized. Please refer to Figure 45 Fig. 11 is a schematic diagram illustrating a single second ball 1142 according to the eleventh embodiment of the present application.

[0129] In the case that the number of the first ball is at least two, the third guide track of the base can further have a stopper, and the stopper separates the at least two first balls which are oppositely arranged with the third guide track. Thus, the first ball is limited to the ideal support position, so that the problem of uneven support force on the lens carrier due to the deviation of the first ball from the originally set support position can be prevented, thereby improving the stability of the imaging lens during the automatic focusing movement. Please refer to Figure 43 Fig. 9 is a schematic diagram illustrating a stopper 9313 of the third guide track 931 according to the ninth embodiment of the present application.

[0130] In the case that the number of the second ball is at least two, the fourth guide track of the base can further have a stopper, and the stopper separates the at least two second balls which are oppositely arranged with the fourth guide track. Thus, the second ball is limited to the ideal support position, so that the problem of uneven support force on the lens carrier due to the deviation of the second ball from the originally set support position can be prevented, thereby improving the stability of the imaging lens during the automatic focusing movement. Please refer to Figure 43 Fig. 9 is a schematic diagram illustrating a stopper 9313 of the third guide track 931 according to the ninth embodiment of the present application.

[0131] Further, the at least one first sphere can have a first sphere center axis. The first sphere center axis can be an axial trajectory of the sphere center of the at least one first sphere moving along a direction parallel to the first guide track. Alternatively, it can also be understood that, in the case where the number of first spheres is at least two, the first sphere center axis can be a line connecting the sphere centers of any two or more of the first spheres located in the same guide track. Through the configuration of the first sphere center axis, the driving unit can maintain high-precision straight movement when driving the lens carrier.

[0132] Further, the at least one second sphere can have a second sphere center axis. The second sphere center axis can be an axial trajectory of the sphere center of the at least one second sphere moving along a direction parallel to the second guide track. Alternatively, it can also be understood that, in the case where the number of second spheres is at least two, the second sphere center axis can be a line connecting the sphere centers of any two or more of the second spheres located in the same guide track. Through the configuration of the second sphere center axis, the driving unit can maintain high-precision straight movement when driving the lens carrier.

[0133] Further, the first sphere center axis, the second sphere center axis, and the optical axis can each intersect a plane perpendicular to the optical axis, and can each have a first intersection point, a second intersection point, and a third intersection point. The first intersection point and the second intersection point can form a first connecting line, the first intersection point and the third intersection point can form a second connecting line, and the second intersection point and the third intersection point can form a third connecting line. A first direction on the plane can be parallel to the first connecting line, and a second direction on the plane can be orthogonal to the first direction.

[0134] Further, the height of each of the first guide track to the fourth guide track along the first direction can be greater than the height of each of the at least one first sphere to the at least one second sphere along the first direction. Note that since the height of each guide track along the first direction can be greater than the height of each sphere along the first direction, from the second direction, each sphere will be obscured by the corresponding guide track, and thus cannot be directly seen along the second direction.

[0135] Further, the height of each of the first guide track to the fourth guide track along the second direction can be greater than the height of each of the at least one first sphere to the at least one second sphere along the second direction. Note that since the height of each guide track along the second direction can be greater than the height of each sphere along the second direction, from the first direction, each sphere will be obscured by the corresponding guide track, and thus cannot be directly seen along the first direction.

[0136] In some embodiments of the present application, the first surface and the fifth surface can have an included angle therebetween. In this way, the design margin of the guide track can be increased to correspond to different driving form requirements. Please refer toFigure 27 is a diagram illustrating an angle Φ2 between the second surface 2212 and the sixth surface 2312 according to the second embodiment of the present application.

[0137] In some embodiments of the present application, the second surface and the sixth surface can have an angle therebetween. Thereby, the design margin of the guide track can be increased to correspond to different driving form requirements. Please refer to Figure 13 is a diagram illustrating an angle Φ2 between the second surface 2212 and the sixth surface 2312 according to the second embodiment of the present application.

[0138] In some embodiments of the present application, the driving unit can further include a flexible printed circuit (FPC), and the at least one coil can be disposed on the flexible printed circuit. Thereby, the flexible printed circuit can be bent to achieve the effect of miniaturization of the imaging lens driving module. The flexible printed circuit can be coupled to the lens carrier. Thereby, the coil can be disposed at an ideal driving position to improve the design margin of the mechanism.
