[0111] The detailed features and advantages of the present utility model are described in detail in the embodiments below. The content is sufficient for any person skilled in the art to understand the technical content of the present utility model and implement it accordingly. And based on the content disclosed in this specification, the scope of the patent application and the drawings, any person skilled in the art can easily understand the related objectives and advantages of the present utility model. The following embodiments further illustrate the viewpoints of the present utility model in detail, but do not limit the scope of the present utility model in any way.

[0112] The present utility model 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.

[0113] 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.

[0114] 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 there is an included angle between the first surface and the second surface. Among them, the included angle between the first surface and the second surface can be a dihedral angle.

[0115] 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 there is an included angle between the third surface and the fourth surface. Among them, the included angle between the third surface and the fourth surface can be a dihedral angle.

[0116] 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 there is an included angle between the fifth surface and the sixth surface. Among them, the included angle between the fifth surface and the sixth surface can be a dihedral angle.

[0117] 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 there is an included angle between the seventh surface and the eighth surface. Among them, the included angle between the seventh surface and the eighth surface can be a dihedral angle.

[0118] The first guiding rail and the third guiding rail are correspondingly arranged. Among them, the first guiding rail and the third guiding rail can be arranged in a "∠ shape" corresponding to a "∠ shape" corresponding setting or a "∟ shape" corresponding to a "∟ shape" setting, but the present utility model is not limited thereto.

[0119] The second guiding rail is correspondingly arranged with the fourth guiding rail. Among them, the second guiding rail and the fourth guiding rail can be arranged in a "∠ shape" corresponding to a "∠ shape" in appearance, corresponding or a "∟ shape" corresponding to a "∟ shape", but the present utility model is not limited thereto.

[0120] Among them, the "∠ shape" of the guiding rail can be understood as the included angle between the two surfaces of the guiding rail being an acute angle, and the can be understood as the included angle between the two surfaces of the guiding rail being an obtuse angle, and the "∟ shape" of the guiding rail can be understood as the included angle between the two surfaces of the guiding rail being a right angle.

[0121] The imaging lens driving module provided by the present utility model further includes a plurality of spheres. The spheres are arranged between the lens carrier and the base. By arranging the spheres, the degree of freedom for the lens carrier to translate relative to the base along the direction parallel to the optical axis can be provided.

[0122] The spheres include at least one first sphere and at least one second sphere. The at least one first sphere is arranged between the first guiding rail and the third guiding rail. The at least one second sphere is arranged between the second guiding rail and the fourth guiding rail.

[0123] Each of the first surface to the eighth surface is in physical contact with the correspondingly arranged sphere only through one contact point. Or, it can also be understood as two-point contact between a single guiding rail and a single sphere. Thereby, the straightness of the movement of the sphere along the direction parallel to the optical axis can be ensured. However, the present utility model is not limited thereto.

[0124] The imaging lens driving module provided by the present utility model further includes a driving unit. The driving unit includes at least one magnet and at least one coil. The at least one magnet and the at least one coil are correspondingly arranged, 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 type driving configuration. When the at least one coil is coupled to the lens carrier, it can be understood as a moving coil type driving configuration.

[0125] The driving unit is used to drive the lens carrier to move relative to the base along the direction parallel to the optical axis. Through the setting of two-point contact between each guiding rail and a single sphere respectively, the lens carrier can move relative to the base along the guiding rail when being driven by the driving unit.

[0126] According to the imaging lens driving module provided by the present utility model discussed above, through the appropriate configuration of the contact point positions between each of the first surface to the eighth surface and the sphere, radial force balance can be achieved in the direction perpendicular to the optical axis, enabling the lens carrier and the base to have an aligning function with each other. Moreover, through each guiding track, the stability of the imaging lens during the autofocus movement can be ensured, thereby improving the imaging quality.

[0127] Furthermore, the number of the at least one first sphere can be at least two. Through the appropriate configuration of the number of the first spheres, the stability of the imaging lens during the autofocus movement can be improved. Further, the number of the at least one second sphere can be at least two. Through the appropriate configuration of the number of the second spheres, the stability of the imaging lens during the autofocus movement can be improved. Alternatively, the number of the at least one second sphere can also be only one. Through the appropriate configuration of the number of the second spheres, the driving efficiency of the imaging lens driving module can be optimized. Please refer to Figure 45 , which is a schematic diagram showing a single second sphere 1142 according to the eleventh embodiment of the present utility model.

[0128] When the number of the first spheres is at least two, the third guiding track of the base can further have a stopper, and the stopper separates the at least two first spheres disposed opposite to the third guiding track. Thereby, the first spheres are restricted to the ideal support positions, so as to prevent the problem of uneven support force received by the lens carrier due to the deviation of the first spheres from the originally set support positions, and to improve the stability of the imaging lens during the autofocus movement. Please refer to Figure 43 , which is a schematic diagram showing the stopper 9313 of the third guiding track 931 according to the ninth embodiment of the present utility model.

[0129] When the number of the second spheres is at least two, the fourth guiding track of the base can further have a stopper, and the stopper separates the at least two second spheres disposed opposite to the fourth guiding track. Thereby, the second spheres are restricted to the ideal support positions, so as to prevent the problem of uneven support force received by the lens carrier due to the deviation of the second spheres from the originally set support positions, and to improve the stability of the imaging lens during the autofocus movement. Please refer to Figure 43 , which is a schematic diagram showing the stopper 9323 of the fourth guiding track 932 according to the ninth embodiment of the present utility model.

[0130] Furthermore, the at least one first sphere may have a first sphere center axis. The first sphere center axis may be an axial trajectory along which the center of the at least one first sphere moves in a direction parallel to the first guiding track. Alternatively, it can also be understood that when the number of first spheres is at least two, the first sphere center axis may be a line connecting the centers of any two or more of the multiple first spheres located on the same guiding track. Through the configuration of the first sphere center axis, the driving unit can maintain high-precision straight-line movement when driving the lens carrier.

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

[0132] Furthermore, the first sphere center axis, the second sphere center axis, and the optical axis may each intersect a plane perpendicular to the optical axis and may respectively have a first intersection point, a second intersection point, and a third intersection point. The first intersection point and the second intersection point may be connected to form a first connection line, the first intersection point and the third intersection point may be connected to form a second connection line, and the second intersection point and the third intersection point may be connected to form a third connection line. A first direction on the plane may be parallel to the first connection line, and a second direction on the plane may be orthogonal to the first direction.

[0133] Furthermore, the height of each of the first guiding track to the fourth guiding track in the first direction may be greater than the height of each of the at least one first sphere to the at least one second sphere in the first direction. Note that since the height of each guiding track in the first direction may be greater than the height of each sphere in the first direction, when observed from the second direction, each sphere will be shielded by the corresponding guiding track, so each sphere cannot be directly seen along the second direction.

[0134] Furthermore, the height of each of the first guiding track to the fourth guiding track in the second direction may be greater than the height of each of the at least one first sphere to the at least one second sphere in the second direction. Note that since the height of each guiding track in the second direction may be greater than the height of each sphere in the second direction, when observed from the first direction, each sphere will be shielded by the corresponding guiding track, so each sphere cannot be directly seen along the first direction.

[0135] In some embodiments of the present utility model, an included angle may exist between the first surface and the fifth surface. Thereby, the design margin of the guiding track can be increased to meet the requirements of different driving forms. Please refer to Figure 27 , which is a schematic diagram showing the included angle Φ2 between the first surface 4211 and the fifth surface 4311 in the fourth embodiment of the present utility model.

[0136] In some embodiments of the present utility model, an included angle may exist between the second surface and the sixth surface.
