DETAILED DESCRIPTION

[0010] In the following detailed description, for purposes of explanation, numerous specific details are set forth in order to provide a thorough understanding of the disclosed embodiments. However, it will be apparent that one or more embodiments may be practiced without these specific details. In other instances, well-known structures and devices are shown schematically to simplify the drawing.

[0011] The present disclosure shows a drive module for an imaging lens comprising an imaging lens, a lens carrier, and a base. The imaging lens has an optical axis. The lens carrier supports the imaging lens. The base is arranged to coincide with the lens carrier.

[0012] The lens carrier includes a first guide path and a second guide path. The base includes a third guide path and a fourth guide path.

[0013] The first guide path extends along a direction parallel to the optical axis. The first guide path has a first surface and a second surface that are connected to each other. The first surface is inclined relative to the second surface. Furthermore, the first surface may be inclined relative to the second surface by a dihedral angle.

[0014] The second guide path extends along a direction parallel to the optical axis. The second guide path has a third surface and a fourth surface that are connected to each other. The third surface is inclined relative to the fourth surface. Furthermore, the third surface may be inclined relative to the fourth surface at a dihedral angle.

[0015] The third guide path extends along a direction parallel to the optical axis. The third guide path has a fifth surface and a sixth surface that are connected to each other. The fifth surface is inclined relative to the sixth surface. Furthermore, the fifth surface may be inclined relative to the sixth surface at a dihedral angle.

[0016] The fourth guide path extends parallel to the optical axis. The fourth guide path has a seventh and an eighth surface that are connected to each other. The seventh surface is inclined relative to the eighth surface. Furthermore, the seventh surface can be inclined relative to the eighth surface at a dihedral angle.

[0017] The first guide path is arranged so as to coincide with the third guide path. Furthermore, the corresponding configuration between the first guide path and the third guide path may be a shape configuration between the "∠-shape" and the "∠-shape", a shape configuration between the " -Form" and the " -shape" or a shape configuration between the "∟-shape" and the "∟-shape". However, the present disclosure is not limited thereto.

[0018] The second guide path is arranged so as to coincide with the fourth guide path. Furthermore, the corresponding configuration between the second guide path and the fourth guide path can have a shape configuration between the “∠-shape” and the "∠-form", a form design between the "-form" and the " -shape" or a shape configuration between the "∟-shape" and the "∟-shape". However, the present disclosure is not limited thereto.

[0019] In addition, the “∠-shape” for describing the guide path can be understood as an angle between two surfaces of the guide path being an acute angle, the “ -shape" to describe the guide path can be understood as meaning that an angle between two surfaces of the guide path is an obtuse angle, and the "∟-shape" to describe the guide path can be understood as meaning that an angle between two surfaces of the guide path is a right angle.

[0020] According to the present disclosure, the imaging lens drive module further comprises a plurality of balls disposed between the lens carrier and the base. The arrangement of the balls advantageously provides degrees of freedom for translational movement of the lens carrier along a direction parallel to the optical axis with respect to the base.

[0021] The plurality of balls comprises at least one first ball and at least one second ball. The at least one first ball is arranged between the first guide path and the third guide path. The at least one second ball is arranged between the second guide path and the fourth guide path.

[0022] Each of the first to eighth surfaces is in physical contact with a correspondingly arranged ball from the plurality of balls through only one contact point. A guide path can also be considered to contact a ball through two points. Therefore, it is advantageous to ensure the rectilinearity of the movement of each ball along a direction parallel to the optical axis. However, the present disclosure is not limited thereto.

[0023] According to the present disclosure, the drive module for an imaging lens further comprises a drive unit. The drive unit comprises at least one magnet and at least one coil arranged in register with one another. One of the at least one magnet and the at least one coil are connected to the lens carrier. In the event that the at least one magnet is connected to the lens carrier, this can be considered a movable magnet configuration. In the event that the at least one coil is connected to the lens carrier, this can be considered a movable coil configuration.

[0024] The drive unit is designed to move the lens carrier relative to the base along a direction parallel to the optical axis. The design of two contact points between each guide path and a ball facilitates the movement of the lens carrier driven by the drive unit along each guide path relative to the base.

[0025] According to the imaging lens drive module of the present disclosure discussed above, by appropriately arranging the contact points between each of the first to eighth surfaces and the balls, it is advantageous to achieve a balance of the radial force along a direction perpendicular to the optical axis, facilitating an alignment function between the lens carrier and the base. Furthermore, each guide path is advantageous in ensuring the stability of the imaging lens during the autofocus movement process, thereby improving image quality.

[0026] In addition, the number of at least one first ball may be at least two. By configuring the appropriate number of the first ball, the stability of the imaging lens is improved during the autofocus movement process. In addition, the number of at least one second ball may be at least two. By configuring the appropriate number of the second ball, the stability of the imaging lens is improved during the autofocus movement process. Alternatively, the number of at least one second ball may be only one. By configuring the appropriate number of the second ball, the drive efficiency of the drive module for an imaging lens is optimized. Fig. 45, which is a schematic view showing a second ball 1142 according to the eleventh embodiment of the present disclosure.

[0027] If the number of first balls is at least two, the third guide path of the base may further include a stopper. The at least two first balls, which coincide with the third guide path, are spaced apart from each other by the stopper of the third guide path. Therefore, it is advantageous to restrict the freedom of movement of the first balls to ideal support positions in order to prevent uneven support forces on the lens carrier caused by displacement of the first balls from the original support positions, thereby improving the stability of the imaging lens during the autofocus movement process. Fig. 43, which is a schematic view showing the stopper 9313 of the third guide path 931 according to the 9th embodiment of the present disclosure.

[0028] If the number of second balls is at least two, the fourth guide path of the base may further comprise a stopper. The at least two second balls, which are arranged in coincidence with the fourth guide path, are spaced apart from each other by the stopper of the fourth guide path. Therefore, it is advantageous to restrict the freedom of movement of the second balls to ideal support positions in order to prevent uneven support forces on the lens carrier caused by a displacement of the second balls from the original support positions, thereby improving the stability of the imaging lens during the autofocus movement process. Fig. 43, which is a schematic view showing the stopper 9323 of the fourth guide path 932 according to the 9th embodiment of the present disclosure.

[0029] Furthermore, the at least one first ball may have a first ball axis. The first ball axis may be formed by an axial movement path of the center point of the at least one first ball along a direction parallel to the first guide path. It can also be considered that the first ball axis may be a connecting line of the centers of two or more first balls located on the same guide path if the number of first balls is at least two. The arrangement of the first ball axis is advantageous for maintaining the straightness of the movement of the lens carrier with high accuracy when it is driven by the drive unit.

[0030] Furthermore, the at least one second ball may have a second ball axis. The second ball axis may be formed by an axial movement path of the center point of the at least one second ball along a direction parallel to the second guide path. It can also be considered that the second ball axis may be a connecting line of the centers of two or more second balls located on the same guide path if the number of second balls is at least two. The arrangement of the second ball axis is advantageous for maintaining the straightness of the movement of the lens carrier with high accuracy when it is driven by the drive unit.

[0031] Furthermore, the first spherical axis, the second spherical axis, and the optical axis may each intersect at a first intersection point, a second intersection point, and a third intersection point with a plane perpendicular to the optical axis. A first line may be defined from the first intersection point to the second intersection point, a second line may be defined from the first intersection point to the third intersection point, and a third line may be defined from the second intersection point to the third intersection point. A first direction located on the plane may be defined as parallel to the first line, and a second direction located on the plane is defined as orthogonal to the first direction.

[0032] Furthermore, the height of each first guide path through the fourth guide path along the first direction may be greater than the height of each of the at least one first sphere through the at least one second sphere along the first direction. Note that since the height of each guide path along the first direction may be greater than the height of each sphere along the first direction, the visibility of each sphere along the second direction would be obstructed by the corresponding guide path, thereby hindering visual inspection of each sphere along the second direction.

[0033] Furthermore, the height of each first guide path to the fourth guide path along 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 along the second direction. It should be noted that since the height of each guide path along the second direction may be greater than the height of each sphere along the second direction, the visibility of each sphere along the first direction would be inhibited by the corresponding guide path, thereby hindering visual inspection of each sphere along the first direction.

[0034] In some embodiments of the present disclosure, the first surface may be inclined relative to the fifth surface. Therefore, it is advantageous to increase the design flexibility of the guide paths to meet different driving requirements. Fig. 27, which is a schematic view disclosing the angle Φ2 between the first surface 4211 and the fifth surface 4311 according to the fourth embodiment of the present disclosure.

[0035] In some embodiments of the present disclosure, the second surface may be inclined relative to the sixth surface. Therefore, it is advantageous to increase the design flexibility of the guide paths to meet different driving requirements. Fig. 13, which is a schematic view disclosing the angle Φ1 between the second surface 2212 and the sixth surface 2312 according to the second embodiment of the present disclosure.

[0036] In some embodiments of the present disclosure, the drive unit may further comprise a flexible printed circuit board (FPC). The at least one coil may be arranged on the flexible printed circuit board. Therefore, due to the bending property of the flexible printed circuit board, it is advantageous to achieve a compact size of the drive module for an imaging lens. Furthermore, the flexible printed circuit board can be connected to the lens carrier. Therefore, this is advantageous for ensuring that the coil is arranged in an ideal drive position, thereby increasing the design freedom of the overall mechanism. Furthermore, the wire of the flexible printed circuit board can be designed with a suitable guide so that the flexible printed circuit board can have an elastic tolerance in a direction parallel to the optical axis when moved together with the lens carrier.This design aims to prevent possible damage or breakage of the flexible circuit board's wire. It is based on . Fig. 28. Fig. 29 and Fig. 30, which are schematic diagrams showing various designs of the wires 5531, 6531, 7531 according to the 5th, 6th and 7th embodiments of the present disclosure.

[0037] If an angle between the second surface and the fourth surface is θ, the following condition can be satisfied: 0° ≤ θ < 130°.

[0038] If an angle between the sixth surface and the eighth surface is θ', the following condition can be satisfied: 0° ≤ θ' < 130°.

[0039] When a distance of the second line projected onto the first line is D1 and a distance of the third line projected onto the first line is D2, the following condition can be satisfied: 1.05 ≤ D1 / D2 < 6. Therefore, it can be seen that the optical axis of the imaging lens is offset from one end of the first line from its center point instead of coinciding with the center point of the first line. This configuration is favorable for effectively utilizing the remaining corner space and thus optimizing space utilization, thereby further meeting the increased spatial requirements when assembling a camera module with the driving module for an imaging lens in a mobile phone. Fig. 9 and Fig. 23, which are schematic diagrams showing D1 and D2 according to the first and third embodiments of the present disclosure.

[0040] If the distance of the second line projected onto the first line is D1 and the distance of the third line projected onto the first line is D2, the following condition can be satisfied: D1 = D2. Therefore, it can be seen that the optical axis of the imaging lens is congruent with the center of the first line. Fig. 39, which is a schematic view showing D1 and D2 of the 8th embodiment of the present disclosure.

[0042] The present disclosure provides an electronic device including the above-mentioned camera module and an image sensor arranged on an image surface of the camera module.

[0043] According to the present disclosure, the above-mentioned features and conditions can be used in numerous combinations to achieve corresponding effects.
