Technical Field

[0001] This invention relates to an imaging lens driving module and an electronic device, and more particularly to an imaging lens driving module suitable for electronic devices. Background Technology

[0002] With advancements in semiconductor technology, the performance of electronic image sensors has improved, allowing pixels to reach smaller sizes. Therefore, optical lenses with high image quality have become an indispensable component. Furthermore, with the rapid development of technology, mobile devices equipped with optical lenses are being used in a wider range of applications, leading to more diverse requirements for these lenses.

[0003] In recent years, electronic products have been trending towards thinner and lighter designs; however, traditional optical lenses can no longer simultaneously meet the demands of miniaturization and high image quality. Modern imaging devices often feature autofocus, optical image stabilization, and zoom capabilities. However, to achieve these functions, the structure of the imaging device has become relatively complex, and its size has increased accordingly, thus increasing the overall size of the electronic device. Furthermore, in the manufacturing process of optical lenses, assembly tolerances between lens components can easily lead to assembly misalignment, thereby reducing the yield rate of optical lenses.

[0147] The following detailed description of the features and advantages of the present invention in the embodiments is sufficient to enable any person skilled in the art to understand the technical content of the present invention and implement it accordingly. Based on the disclosure of this specification, the scope of the claims, and the accompanying drawings, any person skilled in the art can easily understand the related objectives and advantages of the present invention. The following embodiments further illustrate the viewpoints of the present invention in detail, but are not intended to limit the scope of the present invention in any way.

[0148] The present invention provides an imaging lens driving module, which includes an imaging lens, a lens carrier group, a base, a rolling support group and a driving mechanism.

[0149] The imaging lens has multiple optical lenses and has an optical axis passing through the optical lenses.

[0150] The lens carrier assembly includes a first lens carrier and a second lens carrier, wherein the first lens carrier houses at least one optical lens and the second lens carrier houses at least another optical lens.

[0151] The base includes a guide groove assembly, which comprises a first guide groove and a second guide groove. The first guide groove extends along a direction parallel to the optical axis and faces the first lens carrier and the second lens carrier. The second guide groove extends along a direction parallel to the optical axis and is positioned opposite to the first guide groove, also facing the first and second lens carriers. Thus, the first and second lens carriers of the lens carrier assembly share the first and second guide grooves, making the lens carrier assembly a common-track design.

[0152] A rolling support assembly is disposed between the lens carrier assembly and the base, giving the lens carrier assembly a translational degree of freedom relative to the base. The rolling support assembly includes at least one main rolling support and at least one auxiliary rolling support. The main rolling support is disposed between the lens carrier assembly and a first guide groove, and the auxiliary rolling support is disposed between the lens carrier assembly and a second guide groove. The rolling support assembly is in solid contact with both the lens carrier assembly and the base. The first guide groove has two-point contact with the main rolling support to ensure the linearity of the main rolling support's movement along the optical axis, but this is not a limitation of the invention. The second guide groove has a single-point contact with the auxiliary rolling support to compensate for remaining assembly tolerances, but this is not a limitation of the invention. It should be noted that the contact forms between the main rolling support and the auxiliary rolling support and the guide groove are different. The main rolling support and the first guide groove have two-point contact, thus restricting the main rolling support to move only in the direction parallel to the optical axis. The auxiliary rolling support and the second guide groove have a single-point contact, thus allowing the auxiliary rolling support to be slightly offset in the direction perpendicular to the optical axis. This allows the auxiliary rolling support to absorb excess assembly tolerances in addition to supporting the lens carrier assembly.

[0153] The drive mechanism is used to drive the lens carrier assembly to move along the direction parallel to the optical axis. Specifically, the main rolling support of the rolling support assembly allows the lens carrier assembly to move relative to the base along the first guide groove after being driven by the drive mechanism.

[0154] The diameter of the main rolling support in contact with the first lens carrier entity is ΦD1, and the diameter of the auxiliary rolling support in contact with the first lens carrier entity is ΦD2, satisfying the following condition: ΦD1≠ΦD2. Therefore, the different diameters of the main rolling support and the auxiliary rolling support in contact with the same lens carrier entity provide a foolproof effect during the assembly of the imaging lens drive module, improving identification efficiency during the assembly process. Here, ΦD1≠ΦD2 can be, for example, ΦD1<ΦD2 or ΦD1>ΦD2.

[0155] The number of main rolling supports can be multiple, with at least two main rolling supports facing the first lens carrier, and a first buffer support disposed between the at least two main rolling supports. This first buffer support reduces the rolling resistance between the main rolling supports, thereby reducing the driving energy consumption of the imaging lens drive module.

[0156] The number of auxiliary rolling supports can be multiple, with at least two of them facing the first lens carrier, and a second buffer support disposed between the at least two auxiliary rolling supports. This second buffer support reduces the rolling resistance between the auxiliary rolling supports, thereby reducing the driving energy consumption of the imaging lens drive module.

[0157] The diameter of the main rolling support in contact with the first lens carrier is ΦD1, the diameter of the auxiliary rolling support in contact with the first lens carrier is ΦD2, the diameter of the first buffer support is ΦD3, and the diameter of the second buffer support is ΦD4. These diameters satisfy the following conditions: ΦD3 < ΦD1; and ΦD4 < ΦD2. This reduces the driving power consumption of the imaging lens drive module. The lens carrier assembly only makes physical contact with the largest diameter of the main rolling support and the largest diameter of the auxiliary rolling support it faces.

[0158] The number of main rolling supports is N1, and the number of auxiliary rolling supports is N2, which can satisfy the following condition: N2≤N1. Therefore, an appropriate configuration of the number of main and auxiliary rolling supports can optimize the driving efficiency of the imaging lens drive module.

[0159] The imaging lens driving module may further include a light-deflecting element for deflecting an incident light path into at least one optical lens. This arrangement of the light-deflecting element contributes to the miniaturization of the imaging lens driving module. The light-deflecting element may be, for example, a mirror or a prism, but the invention is not limited thereto. Incident light rays from the object side of the imaging lens that have not yet been deflected by the light-deflecting element are defined as the incident light path.

[0160] The present invention also provides an imaging lens driving module, which includes an imaging lens, a lens carrier group, a base, a rolling support group and a driving mechanism.

[0161] The imaging lens has multiple optical lenses and has an optical axis passing through the optical lenses.

[0162] The lens carrier assembly includes a first lens carrier and a second lens carrier, wherein the first lens carrier houses at least one optical lens and the second lens carrier houses at least another optical lens.

[0163] The base includes a guide groove assembly, which comprises a first guide groove, a second guide groove, and a third guide groove. The first guide groove extends along the direction parallel to the optical axis and faces both the first and second lens carriers. The second guide groove extends along the direction parallel to the optical axis and faces only the first lens carrier. The third guide groove extends along the direction parallel to the optical axis and faces only the second lens carrier. More specifically, "facing only the first lens carrier" means that the second guide groove does not face the second lens carrier; similarly, "facing only the second lens carrier" means that the third guide groove does not face the first lens carrier. Thus, the first and second lens carriers of the lens carrier assembly share the first guide groove, making the lens carrier assembly a partially shared-track design.

[0164] A rolling support assembly is disposed between the lens carrier assembly and the base, giving the lens carrier assembly a translational degree of freedom relative to the base. The rolling support assembly includes at least one main rolling support and at least one auxiliary rolling support. The main rolling support is disposed between the lens carrier assembly and the first guide groove, and the auxiliary rolling support is disposed between the lens carrier assembly and other guide grooves besides the first guide groove. The rolling support assembly is in solid contact with the lens carrier assembly and with the base. The first guide groove has two-point contact with the main rolling support to ensure the linearity of the main rolling support's movement along the optical axis, but this is not a limitation of the invention. The other guide grooves besides the first guide groove all have single-point contact with the auxiliary rolling support to compensate for remaining assembly tolerances, but this is not a limitation of the invention. It should be noted that the contact forms between the main rolling support and the auxiliary rolling support and the guide groove are different. The main rolling support and the first guide groove have two-point contact, thus restricting the main rolling support to move only in the direction parallel to the optical axis. The auxiliary rolling support and the other guide grooves besides the first guide groove have single-point contact, thus allowing the auxiliary rolling support to be slightly offset in the direction perpendicular to the optical axis. This allows the auxiliary rolling support to absorb excess assembly tolerances in addition to supporting the lens carrier assembly.

[0165] The drive mechanism is used to drive the lens carrier assembly to move along the direction parallel to the optical axis. Specifically, the main rolling support of the rolling support assembly allows the lens carrier assembly to move relative to the base along the first guide groove after being driven by the drive mechanism.

[0166] The diameter of the main rolling support in contact with the first lens carrier entity is ΦD1, and the diameter of the auxiliary rolling support in contact with the first lens carrier entity is ΦD2, satisfying the following condition: ΦD1≠ΦD2. Therefore, the different diameters of the main rolling support and the auxiliary rolling support in contact with the same lens carrier entity provide a foolproof effect during the assembly of the imaging lens drive module, improving identification efficiency during the assembly process. Here, ΦD1≠ΦD2 can be, for example, ΦD1<ΦD2 or ΦD1>ΦD2.

[0167] The first guide groove can have the same cross-sectional area in the direction parallel to the optical axis. This helps to increase the design margin of the mold and can accommodate the guide groove requirements of different drive types.

[0168] The first guide groove can have different cross-sectional areas in the direction parallel to the optical axis. This allows for the feasibility of integrating the stop mechanism with the base, thereby helping to improve production efficiency.

[0169] The first guide groove may have a gradually widening surface. This allows for a configuration design that improves the stopping effect of the stopping mechanism. The gradually widening surface may, for example, gradually widen from the object side of the imaging lens to the image side along a direction parallel to the optical axis, or it may, for example, gradually widen from the image side of the imaging lens to the object side along a direction parallel to the optical axis; the invention is not limited thereto.

[0170] The number of main rolling supports can be multiple. The minimum width of the expanding surface is W, and the maximum diameter of the main rolling support is ΦD5, which satisfies the following condition: W < ΦD5. This enables the expanding surface to have a stopping mechanism, and this condition range is a dimensional setting that optimizes the stopping effect of the stopping mechanism, limiting the movement range of the main rolling support along the parallel optical axis. The maximum diameter of the main rolling support can refer to the diameter of the main rolling support with the largest diameter among all main rolling supports.

[0171] The present invention also provides an imaging lens driving module, which includes an imaging lens, a lens carrier group, a base, at least two rolling support groups and a driving mechanism.

[0172] The imaging lens has multiple optical lenses and has an optical axis passing through the optical lenses.

[0173] The lens carrier assembly includes a first lens carrier and a second lens carrier, wherein the first lens carrier houses at least one optical lens and the second lens carrier houses at least another optical lens.

[0174] The base includes at least two guide groove groups, each group comprising a first guide groove group and a second guide groove group. The first guide groove group faces the first lens carrier and includes a first guide groove and a second guide groove, both extending parallel to the optical axis, with the second guide groove positioned opposite to the first guide groove. The second guide groove group faces the second lens carrier and includes a third guide groove and a fourth guide groove, both extending parallel to the optical axis, with the fourth guide groove positioned opposite to the third guide groove.

[0175] These rolling support assemblies are disposed between the lens carrier assembly and the base, giving the lens carrier assembly a translational degree of freedom relative to the base. These rolling support assemblies include a first rolling support assembly and a second rolling support assembly. The first rolling support assembly includes at least one first main rolling support and at least one first auxiliary rolling support, wherein the first main rolling support is disposed between the first lens carrier and a first guide groove, and the first auxiliary rolling support is disposed between the first lens carrier and a second guide groove. The second rolling support assembly includes at least one second main rolling support and at least one second auxiliary rolling support, wherein the second main rolling support is disposed between the second lens carrier and a third guide groove, and the second auxiliary rolling support is disposed between the second lens carrier and a fourth guide groove. These rolling support assemblies are in solid contact with the lens carrier assembly and with the base. Both the first and third guide grooves have two-point contact with the main rolling support, thereby ensuring the linearity of the main rolling support's movement along the optical axis, but this invention is not limited thereto. In this invention, all guide grooves other than the first and third guide grooves make single-point contact with the auxiliary rolling support to compensate for remaining assembly tolerances, but this invention is not limited thereto. Specifically, the contact forms between the main rolling support and the auxiliary rolling support and the guide grooves differ. The main rolling support makes two-point contact with either the first or third guide groove, thus restricting its movement to a direction parallel to the optical axis. The auxiliary rolling support makes single-point contact with all guide grooves other than the first and third guide grooves, allowing for slight offset in a direction perpendicular to the optical axis, enabling it to absorb excess assembly tolerances in addition to supporting the lens carrier assembly. The second and fourth guide grooves each make single-point contact with the auxiliary rolling support, absorbing assembly misalignment during assembly and improving the yield rate.

[0176] The drive mechanism is used to drive the lens carrier assembly to move along a direction parallel to the optical axis. Specifically, the first main rolling support allows the first lens carrier to move relative to the base along a first guide groove after being driven by the drive mechanism, and the second main rolling support allows the second lens carrier to move relative to the base along a third guide groove after being driven by the drive mechanism.

[0177] The diameter of the first main rolling support in contact with the first lens carrier entity is ΦD1, and the diameter of the first auxiliary rolling support in contact with the first lens carrier entity is ΦD2, satisfying the following condition: ΦD1≠ΦD2. Therefore, the different diameters of the main rolling support and the auxiliary rolling support in contact with the same lens carrier entity provide a foolproof effect during the assembly of the imaging lens drive module, improving identification efficiency during the assembly process. Here, ΦD1≠ΦD2 can be, for example, ΦD1<ΦD2 or ΦD1>ΦD2.

[0178] The first guide groove group and the second guide groove group may overlap in the direction perpendicular to the optical axis. This helps to increase the design margin of the mold and can accommodate the guide groove requirements of different driving forms. The overlap between the two elements can refer to partial or complete overlap between the two elements.

[0179] The first guide groove group and the second guide groove group may not overlap in the direction parallel to the optical axis. This helps to increase the design margin of the mold and can accommodate the guide groove requirements of different driving types.

[0180] The first guide groove group and the second guide groove group may not overlap in the direction perpendicular to the optical axis. This helps to increase the design margin of the mold and can accommodate the guide groove requirements of different driving types.

[0181] The first guide groove group and the second guide groove group may overlap in the direction parallel to the optical axis. This helps to increase the design margin of the mold and can accommodate the guide groove requirements of different driving forms. The overlap between the two elements can refer to partial or complete overlap between the two elements.

[0182] The present invention also provides an imaging lens driving module, which includes an imaging lens, a lens carrier, a light deflection element, a base, a rolling support assembly, and a driving mechanism.

[0183] The imaging lens has multiple optical lenses and has an optical axis passing through the optical lenses.

[0184] A lens carrier houses at least one optical lens. A light-deflecting element is used to deflect an incident light path into the at least one optical lens. The optical lens includes at least one object-side optical lens, which is located on the object side of the light-deflecting element. An incident light ray from the object side of the imaging lens that has not yet been deflected by the light-deflecting element is defined as the incident light path.

[0185] The base includes a first guide groove and a second guide groove. The first guide groove extends along the direction parallel to the optical axis and faces the lens carrier. The second guide groove extends along the direction parallel to the optical axis and is positioned opposite to the first guide groove, also facing the lens carrier. The light-deflecting element and the base have no relative displacement, and the object-side optical lens and the base also have no relative displacement.

[0186] A rolling support assembly is disposed between the lens carrier and the base, giving the lens carrier a translational degree of freedom relative to the base. The rolling support assembly includes at least one main rolling support and at least one auxiliary rolling support. The main rolling support is disposed between the lens carrier and a first guide groove, and the auxiliary rolling support is disposed between the lens carrier and a second guide groove. The rolling support assembly is in solid contact with both the lens carrier and the base. The first guide groove has two-point contact with the main rolling support to ensure the straight-line movement of the main rolling support along the optical axis, but this is not a limitation of the invention. The second guide groove has a single-point contact with the auxiliary rolling support to compensate for remaining assembly tolerances and absorb assembly misalignment during assembly, thereby improving the yield rate, but this is not a limitation of the invention. It should be noted that the contact forms between the main rolling support and the auxiliary rolling support and the guide groove are different. The main rolling support and the first guide groove have two-point contact, thus restricting the main rolling support to move only in the direction parallel to the optical axis. The auxiliary rolling support and the second guide groove have a single-point contact, thus allowing the auxiliary rolling support to be slightly offset in the direction perpendicular to the optical axis. This allows the auxiliary rolling support to absorb excess assembly tolerances in addition to supporting the lens carrier assembly.

[0187] The drive mechanism is used to drive the lens carrier to move along a direction parallel to the optical axis. Specifically, the main rolling support of the rolling support assembly allows the lens carrier to move relative to the base along the first guide groove after being driven by the drive mechanism.

[0188] The diameter of the main rolling support in contact with the lens carrier is ΦD1, and the diameter of the auxiliary rolling support in contact with the lens carrier is ΦD2, satisfying the condition that ΦD1≠ΦD2. This difference in diameter between the main and auxiliary rolling supports helps prevent mistakes during the assembly of the imaging lens drive module, improving identification efficiency during assembly. For example, ΦD1≠ΦD2 can mean ΦD1<ΦD2 or ΦD1>ΦD2.

[0189] The base may further include a lens carrier structure, which houses at least one other optical lens. This helps to increase the design margin of the optical design, enabling it to meet higher-specification optical requirements.

[0190] There can be no relative displacement between the optical lens housed in the lens carrier structure and the base. This makes it easier to mount the optical lens in the ideal position to improve image quality. Furthermore, only the optical lens housed in the lens carrier and the base can have relative displacement.

[0191] The light-reversing element may include an optical active element, and the incident light path passes through the optical active element. This helps to integrate the light-reversing path function and refractive power into the same light-reversing element, thereby reducing production costs.

[0192] The light-deflecting element converges the incident light path through the optical effective part, and then deflects the incident light path into at least one optical lens. In this way, by configuring the light-deflecting element, the total length of the imaging lens drive module along the optical axis can be shortened, thereby achieving miniaturization.

[0193] The light-reflecting element may include a partial reduction, which occurs from the edge of the light-reflecting element towards its center. This allows for a configuration with better space utilization, contributing to the miniaturization of the imaging lens drive module.

[0194] The object-side optical lens has a central axis and can have an outer diameter reduction structure that decreases along a straight line perpendicular to the central axis. This allows for a configuration with better space utilization, contributing to the miniaturization of the imaging lens drive module.

[0195] The present invention provides an electronic device comprising the aforementioned imaging lens driving module.

[0196] The various technical features in the imaging lens driving module of the present invention can be combined and configured to achieve the corresponding effects.

[0197] Based on the above implementation methods, specific embodiments are presented below and described in detail with reference to the accompanying drawings.

[0198] <First Embodiment>

[0199] Please refer to Figures 1 to 9 ,in Figure 1 A perspective schematic diagram of an imaging lens driving module according to a first embodiment of the present invention is shown. Figure 2 Draw Figure 1 An exploded view of the imaging lens drive module. Figure 3 Draw Figure 1 An exploded view of the other side of the imaging lens drive module. Figure 4 Draw Figure 1 The three-dimensional diagram of the imaging lens drive module does not include the housing. Figure 5 Draw Figure 4 A top-view schematic diagram of the imaging lens drive module. Figure 6 Draw Figure 5 A cross-sectional schematic diagram of the imaging lens drive module along section line 6-6. Figure 7 Draw Figure 5 A cross-sectional schematic diagram of the imaging lens drive module along section line 7-7. Figure 8 Draw Figure 1 A three-dimensional schematic diagram of the base of the imaging lens drive module, and Figure 9 Draw Figure 8 A top view of the base.

[0200] The imaging lens drive module 1 includes a housing 10, an imaging lens 11, a lens carrier assembly 12, a base 13, a rolling support assembly 14, and a drive mechanism 15. The housing 10 is mounted on the base 13, together forming an accommodating space for the lens carrier assembly 12 to be slidably disposed therein. The imaging lens 11 has multiple optical lenses LE, and the imaging lens 11 has an optical axis OA passing through the optical lenses LE.

[0201] The lens carrier group 12 includes a first lens carrier 121 and a second lens carrier 122 sequentially from the object side to the image side. The first lens carrier 121 houses some optical lenses LE, and the second lens carrier 122 houses other optical lenses LE. The number of optical lenses housed by each lens carrier may be one or more, and the present invention is not limited thereto.

[0202] The base 13 includes a guide groove assembly 130, which includes a first guide groove 131, a second guide groove 132, and a third guide groove 133. The first guide groove 131 extends along the direction parallel to the optical axis OA and faces the first lens carrier 121 and the second lens carrier 122. The second guide groove 132 extends along the direction parallel to the optical axis OA and faces only the first lens carrier 121. The third guide groove 133 extends along the direction parallel to the optical axis OA and faces only the second lens carrier 122. Furthermore, the first guide groove 131 extends below the first lens carrier 121 and the second lens carrier 122; the second guide groove 132 does not extend below the second lens carrier 122 and does not face it; and the third guide groove 133 does not extend below the first lens carrier 121 and does not face it. In this embodiment, the first lens carrier 121 and the second lens carrier 122 of the lens carrier group 12 share the first guide groove 131, making the lens carrier group 12 a partially common track design.

[0203] A rolling support assembly 14 is disposed between the lens carrier assembly 12 and the base 13, and the rolling support assembly 14 is in solid contact with both the lens carrier assembly 12 and the base 13, thereby giving the lens carrier assembly 12 a translational degree of freedom relative to the base 13. The rolling support assembly 14 includes four main rolling supports 141 and four auxiliary rolling supports 142. Two main rolling supports 141 are disposed between the first lens carrier 121 and the first guide groove 131, and the other two main rolling supports 141 are disposed between the second lens carrier 122 and the first guide groove 131. Two auxiliary rolling supports 142 are disposed between the first lens carrier 121 and the second guide groove 132, and the other two auxiliary rolling supports 142 are disposed between the second lens carrier 122 and the third guide groove 133. In this embodiment, both the main rolling supports 141 and the auxiliary rolling supports 142 are rigid balls.

[0204] like Figure 6 As shown, the first guide groove 131 has two-point contact with the main rolling support 141, thereby ensuring the straight-line movement of the main rolling support 141 along the optical axis OA. In addition, the second guide groove 132 and the third guide groove 133 both have single-point contact with the auxiliary rolling support 142, thereby compensating for the remaining assembly tolerances.

[0205] like Figure 8 and Figure 9As shown, the first guide groove 131 has different cross-sectional areas in the direction parallel to the optical axis OA, so that a stop mechanism can be formed in the first guide groove 131 with a smaller cross-sectional area to stop the main rolling support 141, and the feasibility of integrally molding the stop mechanism with the base 13 is provided. Furthermore, the first guide groove 131 has a gradually expanding surface GWS, and the gradually expanding surface GWS gradually expands from the object side of the imaging lens 11 to the image side along the direction parallel to the optical axis OA, thereby having a configuration design that improves the stopping effect of the stop mechanism.

[0206] The driving mechanism 15 includes a flexible circuit board 150, multiple driving magnets 151, and multiple driving coils 152. The flexible circuit board 150 is attached to the base 13, the driving magnets 151 are disposed on opposite sides of the lens carrier assembly 12, and the driving coils 152 are disposed on the flexible circuit board 150 and respectively corresponding to the driving magnets 151. The driving mechanism 15 generates a driving force through the driving magnets 151 and the driving coils 152 to drive the lens carrier assembly 12 to move. In conjunction with the main rolling support 141 of the rolling support assembly 14, the lens carrier assembly 12, after being driven by the driving mechanism 15, can move relative to the base 13 along the first guide groove 131 (i.e., along the direction parallel to the optical axis OA). The first lens carrier 121 and the second lens carrier 122 of the lens carrier assembly 12 may have relative displacement.

[0207] The diameter of the main rolling support 141, which is in physical contact with the first lens carrier 121, is ΦD1, and the diameter of the auxiliary rolling support 142, which is also in physical contact with the first lens carrier 121, is ΦD2. The condition ΦD1 < ΦD2 is satisfied. Therefore, the different diameters of the main rolling support and the auxiliary rolling support, which are in physical contact with the same lens carrier, can prevent mistakes during the assembly of the imaging lens drive module and improve the identification efficiency during assembly. In this embodiment, the diameters of the two main rolling supports 141 located between the first lens carrier 121 and the first guide groove 131 can both be ΦD1 and both be in physical contact with the first lens carrier 121; or, due to manufacturing tolerances, only one of the two main rolling supports 141 located between the first lens carrier 121 and the first guide groove 131 may have a diameter of ΦD1 and be in physical contact with the first lens carrier 121, while the other has a diameter smaller than ΦD1 and is not in physical contact with the first lens carrier 121. Similarly, the diameters of the two auxiliary rolling supports 142 located between the first lens carrier 121 and the second guide groove 132 may both be ΦD2 and both be in solid contact with the first lens carrier 121; or, due to manufacturing tolerances, only one of the two auxiliary rolling supports 142 located between the first lens carrier 121 and the second guide groove 132 may have a diameter of ΦD2 and be in solid contact with the first lens carrier 121, while the other may have a diameter smaller than ΦD2 and not be in solid contact with the first lens carrier 121.

[0208] The minimum width of the expanding surface GWS is W, and the diameter of the main rolling support 141 with the largest diameter is ΦD5, satisfying the condition: W < ΦD5. This enables the expanding surface GWS to have a stopping mechanism, and this condition range is a size setting that optimizes the stopping effect of the stopping mechanism, limiting the movement range of the main rolling support 141 along the parallel optical axis OA. In this embodiment, the diameters of the two main rolling supports 141 located between the second lens carrier 122 and the first guide groove 131 can both be ΦD5 and both are in solid contact with the second lens carrier 122; alternatively, due to manufacturing tolerances, only one of the two main rolling supports 141 located between the second lens carrier 122 and the first guide groove 131 may have a diameter of ΦD5 and be in solid contact with the second lens carrier 122, while the other has a diameter smaller than ΦD5 and is not in solid contact with the second lens carrier 122.

[0209] The number of main rolling support members 141 is N1, and the number of auxiliary rolling support members 142 is N2, satisfying the condition that N2 = N1. Therefore, an appropriate configuration of the number of main rolling support members 141 and auxiliary rolling support members 142 optimizes the driving efficiency of the imaging lens drive module 1. In this embodiment, the number of main rolling support members 141 is N1, and the number of auxiliary rolling support members 142 is also N2, which is four.

[0210] <Second Embodiment>

[0211] Please refer to Figures 10 to 18 ,in Figure 10 A perspective schematic diagram of an imaging lens driving module according to a second embodiment of the present invention is shown. Figure 11 Draw Figure 10 An exploded view of the imaging lens drive module. Figure 12 Draw Figure 10 An exploded view of the other side of the imaging lens drive module. Figure 13 Draw Figure 10 The three-dimensional diagram of the imaging lens drive module does not include the housing. Figure 14 Draw Figure 13 A top-view schematic diagram of the imaging lens drive module. Figure 15 Draw Figure 14 A cross-sectional view of the imaging lens drive module along section line 15-15. Figure 16 Draw Figure 14 A cross-sectional view of the imaging lens drive module along section line 16-16. Figure 17 Draw Figure 10 A three-dimensional schematic diagram of the base of the imaging lens drive module, and Figure 18 Draw Figure 17 A top view of the base.

[0212] The imaging lens drive module 1b includes a housing 10b, an imaging lens 11b, a lens carrier assembly 12b, a base 13b, two rolling support assemblies 14b and 24b, and a drive mechanism 15b. The housing 10b is mounted on the base 13b, together forming an accommodating space for the lens carrier assembly 12b to be slidably disposed therein. The imaging lens 11b has multiple optical lenses LE, and the imaging lens 11b has an optical axis OA passing through the optical lenses LE.

[0213] The lens carrier group 12b includes a first lens carrier 121b and a second lens carrier 122b in sequence from the object side to the image side, wherein the first lens carrier 121b houses a portion of the optical lens LE, and the second lens carrier 122b houses other optical lenses LE.

[0214] The base 13b includes two guide groove groups 130b and 230b, which are a first guide groove group 130b and a second guide groove group 230b, respectively. The first guide groove group 130b faces the first lens carrier 121b and includes a first guide groove 131b and a second guide groove 132b. The first guide groove 131b extends along the direction parallel to the optical axis OA, and the second guide groove 132b extends along the direction parallel to the optical axis OA and is disposed opposite to the first guide groove 131b. The second guide groove group 230b faces the second lens carrier 122b, and the second guide groove group 230b includes a third guide groove 231b and a fourth guide groove 232b, wherein the third guide groove 231b extends along the direction parallel to the optical axis OA, and the fourth guide groove 232b extends along the direction parallel to the optical axis OA and is disposed opposite to the third guide groove 231b.

[0215] Rolling support assemblies 14b and 24b are disposed between the lens carrier assembly 12b and the base 13b, and the rolling support assemblies 14b and 24b are in solid contact with the lens carrier assembly 12b and the base 13b, thereby giving the lens carrier assembly 12b a translational degree of freedom relative to the base 13b. The rolling support assemblies 14b and 24b are respectively a first rolling support assembly 14b and a second rolling support assembly 24b. The first rolling support assembly 14b includes two first main rolling supports 141b and two first auxiliary rolling supports 142b, wherein the first main rolling supports 141b are disposed between the first lens carrier 121b and the first guide groove 131b, and the first auxiliary rolling supports 142b are disposed between the first lens carrier 121b and the second guide groove 132b. The second rolling support assembly 24b includes two second main rolling supports 241b and two second auxiliary rolling supports 242b, wherein the second main rolling supports 241b are disposed between the second lens carrier 122b and the third guide groove 231b, and the second auxiliary rolling supports 242b are disposed between the second lens carrier 122b and the fourth guide groove 232b.

[0216] In this embodiment, the first guide groove 131b and the first main rolling support 141b are in two-point contact, and the third guide groove 231b and the second main rolling support 241b are in two-point contact (e.g., Figure 15 As shown), this ensures the linearity of the main rolling supports 141b and 241b moving along the optical axis OA. Furthermore, the second guide groove 132b has a single-point contact with the first auxiliary rolling support 142b, and the fourth guide groove 232b has a single-point contact with the second auxiliary rolling support 242b (as shown). Figure 15 As shown in the figure, this can compensate for the remaining assembly tolerances and absorb the assembly misalignment generated during the assembly process, thereby improving the pass rate.

[0217] The driving mechanism 15b includes a flexible circuit board 150b, multiple driving magnets 151b, and multiple driving coils 152b. The flexible circuit board 150b is attached to the base 13b, the driving magnets 151b are disposed on opposite sides of the lens carrier assembly 12b, and the driving coils 152b are disposed on the flexible circuit board 150b and corresponding to the driving magnets 151b. The driving mechanism 15b generates a driving force through the driving magnets 151b and the driving coils 152b to drive the lens carrier assembly 12b to move. This, in conjunction with the main rolling supports 141b and 241b of the rolling support assemblies 14b and 24b, allows the lens carrier assembly 12b to move relative to the base 13b along the first guide groove 131b and the third guide groove 231b (i.e., along the direction parallel to the optical axis OA), respectively, after being driven by the driving mechanism 15b. The first lens carrier 121b and the second lens carrier 122b of the lens carrier assembly 12b may have relative displacement.

[0218] The diameter of the first main rolling support 141b, which is in physical contact with the first lens carrier 121b, is ΦD1, and the diameter of the first auxiliary rolling support 142b, which is in physical contact with the first lens carrier 121b, is ΦD2, satisfying the condition that ΦD1 > ΦD2. Therefore, the different diameters of the main rolling support and the auxiliary rolling support, which are in physical contact with the same lens carrier, provide a foolproof effect during the assembly of the imaging lens drive module, improving the identification efficiency during the assembly process. In this embodiment, the diameters of the two first main rolling support members 141b located between the first lens carrier 121b and the first guide groove 131b can both be ΦD1 and both are in solid contact with the first lens carrier 121b; or, due to manufacturing tolerances, only one of the two first main rolling support members 141b located between the first lens carrier 121b and the first guide groove 131b has a diameter of ΦD1 and is in solid contact with the first lens carrier 121b, while the other has a diameter smaller than ΦD1 and is not in solid contact with the first lens carrier 121b. Similarly, the diameters of the two first auxiliary rolling supports 142b located between the first lens carrier 121b and the second guide groove 132b may both be ΦD2 and both be in solid contact with the first lens carrier 121b; or, due to manufacturing tolerances, only one of the two first auxiliary rolling supports 142b located between the first lens carrier 121b and the second guide groove 132b may have a diameter of ΦD2 and be in solid contact with the first lens carrier 121b, while the other may have a diameter smaller than ΦD2 and not be in solid contact with the first lens carrier 121b.

[0219] The number of main rolling supports 141b and 241b is N1, and the number of auxiliary rolling supports 142b and 242b is N2, satisfying the condition that N2 = N1. Therefore, an appropriate configuration of the number of main rolling supports 141b and 241b and auxiliary rolling supports 142b and 242b optimizes the driving efficiency of the imaging lens drive module 1b. In this embodiment, the number of the first main rolling support 141b plus the second main rolling support 241b is four (N1), and the number of the first auxiliary rolling support 142b plus the second auxiliary rolling support 242b is also four (N2).

[0220] like Figure 17 and Figure 18 As shown, the first guide groove group 130b (i.e., the first guide groove 131b and the second guide groove 132b) and the second guide groove group 230b (i.e., the third guide groove 231b and the fourth guide groove 232b) do not overlap in the direction parallel to the optical axis OA, and the first guide groove group 130b and the second guide groove group 230b also do not overlap in the direction perpendicular to the optical axis OA. This helps to increase the design margin of the mold and can accommodate the guide groove requirements of different driving forms.

Figure 27 Draw Figure 25 A cross-sectional view of the imaging lens drive module along section line 27-27. Figure 28 Draw Figure 21 A three-dimensional schematic diagram of the base of the imaging lens drive module, and Figure 29 Draw Figure 28 A top view of the base.

[0226] The imaging lens drive module 1c includes a housing 10c, an imaging lens 11c, a lens carrier assembly 12c, a base 13c, a rolling support assembly 14c, and a drive mechanism 15c. The housing 10c is mounted on the base 13c, together forming an accommodating space for the lens carrier assembly 12c to be slidably disposed therein. The imaging lens 11c has multiple optical lenses LE, and the imaging lens 11c has an optical axis OA passing through the optical lenses LE.

[0227] The lens carrier group 12c includes a first lens carrier 121c and a second lens carrier 122c sequentially from the object side to the image side, wherein the first lens carrier 121c houses a portion of the optical lens LE, and the second lens carrier 122c houses other optical lenses LE.

[0228] The base 13c includes a guide groove group 130c, and the guide groove group 130c includes a first guide groove 131c, a second guide groove 132c and a third guide groove 133c. The first guide groove 131c extends along the direction parallel to the optical axis OA and faces the first lens carrier 121c and the second lens carrier 122c. The second guide groove 132c extends along the direction parallel to the optical axis OA and faces only the first lens carrier 121c. The third guide groove 133c extends along the direction parallel to the optical axis OA and faces only the second lens carrier 122c. Furthermore, the first guide groove 131c extends below the first lens carrier 121c and the second lens carrier 122c, the second guide groove 132c does not extend below the second lens carrier 122c and does not face the second lens carrier 122c, and the third guide groove 133c does not extend below the first lens carrier 121c and does not face the first lens carrier 121c. In this embodiment, the first lens carrier 121c and the second lens carrier 122c of the lens carrier group 12c share the first guide groove 131c, making the lens carrier group 12c a partially common-track design.

[0229] A rolling support assembly 14c is disposed between the lens carrier assembly 12c and the base 13c, and the rolling support assembly 14c is in solid contact with both the lens carrier assembly 12c and the base 13c, thereby giving the lens carrier assembly 12c a translational degree of freedom relative to the base 13c. The rolling support assembly 14c includes four main rolling supports 141c and four auxiliary rolling supports 142c, wherein two main rolling supports 141c are disposed between the first lens carrier 121c and the first guide groove 131c, and the other two main rolling supports 141c are disposed between the second lens carrier 122c and the first guide groove 131c, and two auxiliary rolling supports 142c are disposed between the first lens carrier 121c and the second guide groove 132c, and the other two auxiliary rolling supports 142c are disposed between the second lens carrier 122c and the third guide groove 133c.

[0230] like Figure 26 As shown, the first guide groove 131c has two-point contact with the main rolling support 141c, thereby ensuring the straight-line movement of the main rolling support 141c along the optical axis OA. In addition, the second guide groove 132c and the third guide groove 133c both have single-point contact with the auxiliary rolling support 142c, thereby compensating for the remaining assembly tolerances.

[0231] like Figure 28 and Figure 29 As shown, the first guide groove 131c has the same cross-sectional area in the direction parallel to the optical axis OA, which helps to increase the design margin of the mold and can meet the guide groove requirements of different driving forms.

[0232] The driving mechanism 15c includes a flexible circuit board 150c, multiple driving magnets 151c, and multiple driving coils 152c. The flexible circuit board 150c is attached to the base 13c, the driving magnets 151c are disposed on opposite sides of the lens carrier assembly 12c, and the driving coils 152c are disposed on the flexible circuit board 150c and respectively corresponding to the driving magnets 151c. The driving mechanism 15c generates a driving force through the driving magnets 151c and the driving coils 152c to drive the lens carrier assembly 12c to move. In conjunction with the main rolling support 141c of the rolling support assembly 14c, the lens carrier assembly 12c can move relative to the base 13c along the first guide groove 131c (i.e., along the direction parallel to the optical axis OA) after being driven by the driving mechanism 15c. The first lens carrier 121c and the second lens carrier 122c of the lens carrier assembly 12c may have relative displacement.

[0233] The diameter of the main rolling support 141c, which is in physical contact with the first lens carrier 121c, is ΦD1, and the diameter of the auxiliary rolling support 142c, which is also in physical contact with the first lens carrier 121c, is ΦD2. The condition ΦD1 > ΦD2 is satisfied. Therefore, the different diameters of the main rolling support and the auxiliary rolling support, which are in physical contact with the same lens carrier, can prevent mistakes during the assembly of the imaging lens drive module and improve the identification efficiency during assembly. In this embodiment, the diameters of the two main rolling supports 141c located between the first lens carrier 121c and the first guide groove 131c can both be ΦD1 and both be in physical contact with the first lens carrier 121c; or, due to manufacturing tolerances, only one of the two main rolling supports 141c located between the first lens carrier 121c and the first guide groove 131c may have a diameter of ΦD1 and be in physical contact with the first lens carrier 121c, while the other has a diameter smaller than ΦD1 and is not in physical contact with the first lens carrier 121c. Similarly, the diameters of the two auxiliary rolling supports 142c located between the first lens carrier 121c and the second guide groove 132c may both be ΦD2 and both be in solid contact with the first lens carrier 121c; or, due to manufacturing tolerances, only one of the two auxiliary rolling supports 142c located between the first lens carrier 121c and the second guide groove 132c may have a diameter of ΦD2 and be in solid contact with the first lens carrier 121c, while the other may have a diameter smaller than ΦD2 and not be in solid contact with the first lens carrier 121c.

[0234] Furthermore, in this embodiment, the diameters of the two main rolling support members 141c located between the second lens carrier 122c and the first guide groove 131c can both be ΦD6 and both be in solid contact with the second lens carrier 122c; alternatively, due to manufacturing tolerances, only one of the two main rolling support members 141c located between the second lens carrier 122c and the first guide groove 131c may have a diameter of ΦD6 and be in solid contact with the second lens carrier 122c, while the other may have a diameter smaller than ΦD6 and not be in solid contact with the second lens carrier 122c. ΦD6 and ΦD1 may be equal or unequal, and this invention is not limited thereto.

[0235] The number of main rolling support members 141c is N1, and the number of auxiliary rolling support members 142c is N2, satisfying the condition that N2 = N1. Therefore, an appropriate configuration of the number of main rolling support members 141c and auxiliary rolling support members 142c optimizes the driving efficiency of the imaging lens drive module 1c. In this embodiment, the number of main rolling support members 141c is N1, and the number of auxiliary rolling support members 142c is also N2, which is four.

[0236] <Fourth Embodiment>

[0237] Please refer to Figures 30 to 39 ,in Figure 30 A perspective schematic diagram of an imaging lens driving module according to a fourth embodiment of the present invention is shown. Figure 31 Draw Figure 30 An exploded view of the imaging lens drive module. Figure 32 Draw Figure 30 An exploded view of the other side of the imaging lens drive module.

Figure 39 Draw Figure 38 A top view schematic diagram of the base, rolling support assembly, buffer support assembly, and light deflection element.

[0238] The imaging lens drive module 1d includes a housing 10d, an imaging lens 11d, a lens carrier group 12d, a light deflection element 16d, a base 13d, a rolling support group 14d, and a drive mechanism 15d. The housing 10d is mounted on the base 13d, together forming an accommodating space for the lens carrier group 12d to be slidably disposed therein. The imaging lens 11d has multiple optical lenses LE, and the imaging lens 11d has an optical axis OA passing through the optical lenses LE.

[0239] The lens carrier group 12d includes a first lens carrier 121d and a second lens carrier 122d sequentially from the object side to the image side, wherein the first lens carrier 121d houses a portion of the optical lens LE, and the second lens carrier 122d houses other optical lenses LE.

[0240] A light-deflecting element 16d is disposed on the base 13d and located on the object side of the lens carrier group 12d, and is used to deflect the incident light path PL into the optical lens LE, which helps to miniaturize the imaging lens drive module 1d. In this embodiment, the light-deflecting element 16d is a prism.

[0241] The base 13d includes a guide groove assembly 130d, which includes a first guide groove 131d and a second guide groove 132d. The first guide groove 131d extends along the direction parallel to the optical axis OA and faces the first lens carrier 121d and the second lens carrier 122d. The second guide groove 132d extends along the direction parallel to the optical axis OA and is opposite to the first guide groove 131d, and faces the first lens carrier 121d and the second lens carrier 122d. In this embodiment, the first lens carrier 121d and the second lens carrier 122d of the lens carrier assembly 12d share the first guide groove 131d and the second guide groove 132d, making the lens carrier assembly 12d a common track design.

[0242] A rolling support assembly 14d is disposed between the lens carrier assembly 12d and the base 13d, and the rolling support assembly 14d is in solid contact with both the lens carrier assembly 12d and the base 13d, thereby giving the lens carrier assembly 12d a translational degree of freedom relative to the base 13d. The rolling support assembly 14d includes four main rolling supports 141d and three auxiliary rolling supports 142d. Two main rolling supports 141d are disposed between the first lens carrier 121d and the first guide groove 131d, and two other main rolling supports 141d are disposed between the second lens carrier 122d and the first guide groove 131d. Two auxiliary rolling supports 142d are disposed between the first lens carrier 121d and the second guide groove 132d, and the other auxiliary rolling support 142d is disposed between the second lens carrier 122d and the second guide groove 132d.

[0243] A first buffer support 171d is provided between the two main rolling support members 141d facing the first lens carrier 121d to reduce the rolling resistance between the main rolling support members 141d, thereby reducing the driving energy consumption of the imaging lens drive module 1d. In addition, another first buffer support 171d is also provided between the two main rolling support members 141d facing the second lens carrier 122d.

[0244] A second buffer support 172d is provided between the two auxiliary rolling support members 142d facing the first lens carrier 121d, so as to reduce the rolling resistance between the auxiliary rolling support members 142d, thereby reducing the driving energy consumption of the imaging lens drive module 1d.

[0245] like Figure 37 As shown, the first guide groove 131d and the main rolling support 141d are in two-point contact, thereby ensuring the linearity of the main rolling support 141d's movement along the optical axis OA. Additionally, as... Figure 35 As shown, the second guide groove 132d and the auxiliary rolling support 142d are in single-point contact, which can compensate for the remaining assembly tolerance.

[0246] like Figure 38 and Figure 39 As shown, the first guide groove 131d has the same cross-sectional area in the direction parallel to the optical axis OA, which helps to increase the design margin of the mold and can meet the guide groove requirements of different driving forms.

[0247] The driving mechanism 15d includes a flexible circuit board 150d, multiple driving magnets 151d, and multiple driving coils 152d. The flexible circuit board 150d is attached to the outer casing 10d. The driving magnets 151d are disposed on opposite sides of the lens carrier assembly 12d, with the driving magnets 151d on one side all disposed on the first lens carrier 121d, and the driving magnets 151d on the other side all disposed on the second lens carrier 122d. The driving coils 152d are disposed on the flexible circuit board 150d and are respectively disposed corresponding to the driving magnets 151d. The driving mechanism 15d generates a driving force through the driving magnets 151d and the driving coils 152d to drive the lens carrier assembly 12d to move. In conjunction with the main rolling support 141d of the rolling support assembly 14d, the lens carrier assembly 12d can move relative to the base 13d along the first guide groove 131d (i.e., along the direction parallel to the optical axis OA) after being driven by the driving mechanism 15d. Among them, the first lens carrier 121d and the second lens carrier 122d of the lens carrier group 12d may have relative displacement.

[0248] The diameter of the main rolling support 141d, which is in physical contact with the first lens carrier 121d, is ΦD1, and the diameter of the auxiliary rolling support 142d, which is also in physical contact with the first lens carrier 121d, is ΦD2, satisfying the condition that ΦD1 < ΦD2. Therefore, the different diameters of the main rolling support and the auxiliary rolling support, which are in physical contact with the same lens carrier, can prevent mistakes during the assembly of the imaging lens drive module and improve the identification efficiency during the assembly process. In this embodiment, the diameters of the two main rolling supports 141d located between the first lens carrier 121d and the first guide groove 131d can both be ΦD1 and both be in physical contact with the first lens carrier 121d; or, due to manufacturing tolerances, only one of the two main rolling supports 141d located between the first lens carrier 121d and the first guide groove 131d may have a diameter of ΦD1 and be in physical contact with the first lens carrier 121d, while the other has a diameter smaller than ΦD1 and is not in physical contact with the first lens carrier 121d. Similarly, the diameters of the two auxiliary rolling supports 142d located between the first lens carrier 121d and the second guide groove 132d may both be ΦD2 and both be in solid contact with the first lens carrier 121d; or, due to manufacturing tolerances, only one of the two auxiliary rolling supports 142d located between the first lens carrier 121d and the second guide groove 132d may have a diameter of ΦD2 and be in solid contact with the first lens carrier 121d, while the other may have a diameter smaller than ΦD2 and not be in solid contact with the first lens carrier 121d.

[0249] Furthermore, in this embodiment, the two main rolling supports 141d located between the second lens carrier 122d and the first guide groove 131d may both have a diameter of ΦD5 and both be in physical contact with the second lens carrier 122d; alternatively, due to manufacturing tolerances, only one of the two main rolling supports 141d located between the second lens carrier 122d and the first guide groove 131d has a diameter of ΦD5 and is in physical contact with the second lens carrier 122d, while the other has a diameter smaller than ΦD5 and is not in physical contact with the second lens carrier 122d. Wherein, ΦD5 and ΦD1 may be equal or unequal, and the present invention is not limited thereto.

[0250] The diameter of the main rolling support 141d in physical contact with the first lens carrier 121d is ΦD1, the diameter of the auxiliary rolling support 142d in physical contact with the first lens carrier 121d is ΦD2, the diameter of the first buffer support 171d is ΦD3, and the diameter of the second buffer support 172d is ΦD4, which satisfy the following conditions: ΦD3<ΦD1; and ΦD4<ΦD2. Thereby, the driving energy consumption of the imaging lens driving module 1d can be reduced.

[0251] The number of the main rolling supports 141d is N1, the number of the auxiliary rolling supports 142d is N2, which satisfy the following condition: N2<N1. Thereby, the proper configuration of the numbers of the main rolling supports 141d and the auxiliary rolling supports 142d can optimize the driving efficiency of the imaging lens driving module 1d. In this embodiment, the number N1 of the main rolling supports 141d is four, and the number N2 of the auxiliary rolling supports 142d is three.

[0252] <Fifth Embodiment>

[0253] Please refer to Figures 40 to 49 , wherein Figure 40 illustrates a perspective schematic view of an imaging lens driving module according to the fifth embodiment of the present invention, Figure 41 illustrates Figure 40 an exploded schematic view of the imaging lens driving module, Figure 42 illustrates Figure 40 another side exploded schematic view of the imaging lens driving module, Figure 43 illustrates Figure 40 a perspective schematic view of the imaging lens driving module without a housing, Figure 44 illustrates Figure 43 a cross-sectional schematic view of the imaging lens driving module, Figure 45 illustrates Figure 43 a top schematic view of the imaging lens driving module, Figure 46 illustrates Figure 45 a cross-sectional schematic view of the imaging lens driving module taken along section line 46-46, Figure 47 illustrates Figure 45A cross-sectional view of the imaging lens drive module along section line 47-47. Figure 48 Draw Figure 40 A three-dimensional schematic diagram of the base, rolling support assembly, and part of the image-side optical lens of the imaging lens drive module. Figure 49 Draw Figure 48 A top view of the base and rolling support assembly.

[0254] The imaging lens drive module 1e includes a housing 10e, an imaging lens 11e, a lens carrier 12e, a light deflection element 16e, a base 13e, a rolling support assembly 14e, and a drive mechanism 15e. The housing 10e is mounted on the base 13e and together they form an accommodating space for the lens carrier 12e to be slidably disposed therein.

[0255] The imaging lens 11e has multiple optical lenses LE and an optical axis OA passing through the optical lenses LE. The optical lenses LE include multiple object-side optical lenses OLE and multiple image-side optical lenses ILE, wherein the object-side optical lenses OLE are located on the object side of the image-side optical lenses ILE. In this embodiment, the object-side optical lenses OLE have a central axis CA and an outer diameter reduction structure ORS that decreases along a straight line perpendicular to the central axis CA, thereby achieving a configuration with better space utilization and contributing to the miniaturization of the imaging lens driving module.

[0256] Lens carrier 12e houses a portion of the image-side optical lens ILE. A light-deflecting element 16e is located on the object side of lens carrier 12e and on the image side of the object-side optical lens ILE, used to deflect the incident light path PL into the image-side optical lens ILE, which contributes to the miniaturization of the imaging lens drive module 1e. In this embodiment, the light-deflecting element 16e is a prism, and includes a partially reduced LR, which tapers from the edge of the light-deflecting element 16e towards its center, thereby achieving a configuration with better space utilization, contributing to the miniaturization of the imaging lens drive module 1e.

[0257] The base 13e includes a first guide groove 131e, a second guide groove 132e, and a lens carrier structure 134e. The first guide groove 131e extends along the direction parallel to the optical axis OA and faces the lens carrier 12e. The second guide groove 132e extends along the direction parallel to the optical axis OA and is positioned opposite to the first guide groove 131e, with the second guide groove 132e facing the lens carrier 12e. The lens carrier structure 134e accommodates other image-side optical lenses ILE, which helps to increase the design margin of optical designs and can meet higher-specification optical requirements.

[0258] In this embodiment, there is no relative displacement between the image-side optical lens ILE housed in the lens carrier structure 134e and the base 13e. This makes it easier to mount the optical lens in the ideal position to improve image quality. Understandably, only the image-side optical lens ILE housed in the lens carrier 12e and the base 13e may have relative displacement.

[0259] In this embodiment, the light-deflecting element 16e and the base 13e have no relative displacement, and the object-side optical lens OLE and the base 13e also have no relative displacement.

[0260] A rolling support assembly 14e is disposed between the lens carrier 12e and the base 13e, and the rolling support assembly 14e is in solid contact with both the lens carrier 12e and the base 13e, thereby giving the lens carrier 12e a translational degree of freedom relative to the base 13e. The rolling support assembly 14e includes two main rolling supports 141e and two auxiliary rolling supports 142e, wherein the main rolling supports 141e are disposed between the lens carrier 12e and the first guide groove 131e, and the auxiliary rolling supports 142e are disposed between the lens carrier 12e and the second guide groove 132e.

[0261] like Figure 46 As shown, the first guide groove 131e and the main rolling support 141e have two-point contact, which ensures the straightness of the main rolling support 141e's movement along the optical axis OA. Furthermore, the second guide groove 132e and the auxiliary rolling support 142e have a single-point contact, which compensates for remaining assembly tolerances and absorbs assembly misalignment generated during assembly, thereby improving the yield rate.

[0262] The driving mechanism 15e includes a flexible circuit board 150e, multiple driving magnets 151e, and multiple driving coils 152e. The flexible circuit board 150e is attached to the base 13e, the driving magnets 151e are disposed on opposite sides of the lens carrier 12e, and the driving coils 152e are disposed on the flexible circuit board 150e and respectively corresponding to the driving magnets 151e. The driving mechanism 15e generates a driving force through the driving magnets 151e and the driving coils 152e to drive the lens carrier 12e to move. In conjunction with the main rolling support 141e of the rolling support assembly 14e, the lens carrier 12e can move relative to the base 13e along the first guide groove 131e (that is, along the direction parallel to the optical axis OA) after being driven by the driving mechanism 15e.

[0263] The diameter of the main rolling support 141e, which is in contact with the lens carrier 12e, is ΦD1, and the diameter of the auxiliary rolling support 142e, which is also in contact with the lens carrier 12e, is ΦD2. The condition that ΦD1 > ΦD2 is satisfied. This difference in diameter between the main and auxiliary rolling supports in contact with the lens carrier provides a foolproof design for the assembly of the imaging lens drive module, improving identification efficiency during assembly. In this embodiment, both main rolling supports 141e may have a diameter of ΦD1 and both may be in contact with the lens carrier 12e; alternatively, due to manufacturing tolerances, only one of the main rolling supports 141e may have a diameter of ΦD1 and be in contact with the lens carrier 12e, while the other may have a diameter smaller than ΦD1 and not be in contact with the lens carrier 12e. Similarly, the diameters of the two auxiliary rolling supports 142e may both be ΦD2 and both be in solid contact with the lens carrier 12e; or, due to manufacturing tolerances, only one of the two auxiliary rolling supports 142e may have a diameter of ΦD2 and be in solid contact with the lens carrier 12e, while the other may have a diameter smaller than ΦD2 and not be in solid contact with the lens carrier 12e.

[0264] The number of main rolling support members 141e is N1, and the number of auxiliary rolling support members 142e is N2, satisfying the condition that N2 = N1. Therefore, an appropriate configuration of the number of main rolling support members 141e and auxiliary rolling support members 142e optimizes the driving efficiency of the imaging lens drive module 1e. In this embodiment, the number of main rolling support members 141e is N1, and the number of auxiliary rolling support members 142e is also N2.

The housing 10f is mounted on the base 13f and together they form an accommodating space for the lens carrier 12f to be slidably disposed therein.

[0268] The imaging lens 11f has multiple optical lenses LE and an optical axis OA passing through the optical lenses LE. The optical lenses LE include multiple object-side optical lenses OLE and multiple image-side optical lenses ILE, wherein the object-side optical lenses OLE are located on the object side of the image-side optical lenses ILE. In this embodiment, the object-side optical lenses OLE have a central axis CA and an outer diameter reduction structure ORS that decreases along a straight line perpendicular to the central axis CA, thereby achieving a configuration with better space utilization and contributing to the miniaturization of the imaging lens driving module.

[0269] Lens carrier 12f houses the image-side optical lens ILE. A light-deflecting element 16f is located on the object side of lens carrier 12f and on the image side of the object-side optical lens ILE, used to deflect the incident light path PL into the image-side optical lens ILE, which contributes to the miniaturization of the imaging lens drive module 1f. In this embodiment, the light-deflecting element 16f is a prism, and includes a partial reduction LR and an optically effective part OER. The partial reduction LR decreases from the edge of the light-deflecting element 16f towards its center, thereby achieving a configuration with better space utilization, contributing to the miniaturization of the imaging lens drive module 1f. Figure 56 As shown, when the incident light path PL passes through the optical effective part OER of the light-reflecting element 16f, the optical effective part OER converges the incident light path PL and then reflects the incident light path PL into the image-side optical lens ILE. This helps to integrate the light-reflecting function and diopter on the same light-reflecting element, which can reduce production costs. Furthermore, by configuring the light-reflecting element, the total length of the imaging lens drive module along the optical axis can be shortened, thereby achieving miniaturization.

[0270] The base 13f includes a first guide groove 131f and a second guide groove 132f. The first guide groove 131f extends along the direction parallel to the optical axis OA and faces the lens carrier 12f. The second guide groove 132f extends along the direction parallel to the optical axis OA and is disposed opposite to the first guide groove 131f, and the second guide groove 132f faces the lens carrier 12f.

[0271] In this embodiment, the light-deflecting element 16f and the base 13f have no relative displacement, and the object-side optical lens OLE and the base 13f also have no relative displacement.

[0272] A rolling support assembly 14f is disposed between the lens carrier 12f and the base 13f, and the rolling support assembly 14f is in solid contact with both the lens carrier 12f and the base 13f, thereby giving the lens carrier 12f a translational degree of freedom relative to the base 13f. The rolling support assembly 14f includes two main rolling supports 141f and two auxiliary rolling supports 142f, wherein the main rolling supports 141f are disposed between the lens carrier 12f and the first guide groove 131f, and the auxiliary rolling supports 142f are disposed between the lens carrier 12f and the second guide groove 132f.

[0273] like Figure 55 As shown, the first guide groove 131f and the main rolling support 141f have two-point contact, which ensures the straightness of the main rolling support 141f's movement along the optical axis OA. Furthermore, the second guide groove 132f and the auxiliary rolling support 142f have a single-point contact, which compensates for remaining assembly tolerances and absorbs assembly misalignment generated during assembly, thereby improving the yield rate.

[0274] The driving mechanism 15f includes a flexible circuit board 150f, multiple driving magnets 151f, and multiple driving coils 152f. The flexible circuit board 150f is attached to the base 13f, the driving magnets 151f are disposed on opposite sides of the lens carrier 12f, and the driving coils 152f are disposed on the flexible circuit board 150f and respectively corresponding to the driving magnets 151f. The driving mechanism 15f generates a driving force through the driving magnets 151f and the driving coils 152f to drive the lens carrier 12f to move. In conjunction with the main rolling support 141f of the rolling support assembly 14f, the lens carrier 12f can move relative to the base 13f along the first guide groove 131f (i.e., along the direction parallel to the optical axis OA) after being driven by the driving mechanism 15f.

[0275] The diameter of the main rolling support 141f, which is in contact with the lens carrier 12f, is ΦD1, and the diameter of the auxiliary rolling support 142f, which is also in contact with the lens carrier 12f, is ΦD2. The condition that ΦD1 > ΦD2 is satisfied. This difference in diameter between the main and auxiliary rolling supports in contact with the lens carrier provides a foolproof design for the assembly of the imaging lens drive module, improving identification efficiency during assembly. In this embodiment, both main rolling supports 141f may have a diameter of ΦD1 and both may be in contact with the lens carrier 12f; alternatively, due to manufacturing tolerances, only one of the main rolling supports 141f may have a diameter of ΦD1 and be in contact with the lens carrier 12f, while the other may have a diameter smaller than ΦD1 and not be in contact with the lens carrier 12f. Similarly, the diameters of the two auxiliary rolling supports 142f may both be ΦD2 and both be in solid contact with the lens carrier 12f; or, due to manufacturing tolerances, only one of the two auxiliary rolling supports 142f may have a diameter of ΦD2 and be in solid contact with the lens carrier 12f, while the other may have a diameter smaller than ΦD2 and not be in solid contact with the lens carrier 12f.

[0276] The number of main rolling support members 141f is N1, and the number of auxiliary rolling support members 142f is N2, satisfying the condition that N2 = N1. Therefore, an appropriate configuration of the number of main rolling support members 141f and auxiliary rolling support members 142f optimizes the driving efficiency of the imaging lens drive module 1f. In this embodiment, the number of main rolling support members 141f is N1, and the number of auxiliary rolling support members 142f is also N2.

[0277] <Seventh Embodiment>

[0278] Please refer to Figures 59 to 61 ,in Figure 59 A perspective schematic diagram of an electronic device according to a seventh embodiment of the present invention is shown. Figure 60 Draw Figure 59 A three-dimensional diagram of the other side of the electronic device, and Figure 61 Draw Figure 59 System block diagram of an electronic device.

[0279] In this embodiment, the electronic device 4 is a mobile device, which can be a computer, smartphone, smart wearable device, drone, or vehicle image recording and display instrument, etc., and the present invention is not limited thereto. The electronic device 4 includes image capturing devices 4k, 4a, 4b, 4c, 4d, 4e, 4f, and 4g, a flash module 42, a focus assist module 43, an image signal processor 44, a display device 45, an image software processor 46, and a biometric sensor 50. Among them, the image capturing device 4k includes the imaging lens driving module 1d, an electronic photosensitive element, and an image stabilization module of the fourth embodiment, and the image capturing device 4a includes the imaging lens driving module 1, a light deflection element (not shown), an electronic photosensitive element, and an image stabilization module of the first embodiment.

[0280] Image capturing devices 4k, 4a, 4b, 4c, and 4d are all disposed on the same side of electronic device 4. Image capturing devices 4e, 4f, 4g, and display device 45 are all disposed on the other side of electronic device 4, and display device 45 can be a user interface so that image capturing devices 4e and 4f can be used as front-facing cameras to provide selfie functionality, but the present invention is not limited thereto.

[0281] Image capturing devices 4b, 4c, 4d, 4e, 4f, and 4g may all include the imaging lens driving module of the present invention and may all have a structural configuration similar to that of image capturing device 4k or image capturing device 4a. For example, image capturing devices 4b, 4c, 4d, 4e, 4f, and 4g may each include an imaging lens driving module, an electronic photosensitive element, and an image stabilization module.

[0282] Image capturing device 4k is a super telephoto image capturing device, image capturing device 4a is a zoom telephoto image capturing device, image capturing device 4b is a wide-angle image capturing device, image capturing device 4c is an ultra-wide-angle image capturing device, image capturing device 4d is a macro image capturing device, image capturing device 4e is an ultra-wide-angle image capturing device, image capturing device 4f is a wide-angle image capturing device, and image capturing device 4g is a Time of Flight (ToF) image capturing device. In this embodiment, image capturing devices 4k, 4a, 4b, 4c, and 4d have different viewing angles, allowing the electronic device 4 to provide different magnifications to achieve optical zoom shooting effects. For example, ultra-wide-angle image capturing devices 4c or 4e have a maximum viewing angle of 105 to 125 degrees, which can achieve an image with an equivalent focal length between 11mm and 14mm. The image captured under these conditions can be referenced... Figure 62 The illustration shows an image captured by electronic device 4 with an equivalent focal length between 11mm and 14mm, in which the captured image includes the entire church, surrounding buildings and people in the square. Figure 62 Images captured using this method have a wide angle of view and depth of field, but are often accompanied by significant distortion. Wide-angle imaging devices 4b or 4f have a maximum angle of view of 70 to 90 degrees, achieving an equivalent focal length between 22mm and 30mm. Images captured under these conditions can be referenced... Figure 63 The illustration shows an image captured by electronic device 4 at an equivalent focal length between 22mm and 30mm, where the captured image includes the entire church and the people in front of it. The variable-focus telephoto imaging device 4a has a maximum viewing angle of 10 to 40 degrees, achieving an image with an equivalent focal length between 60mm and 300mm, and can be considered to provide a magnification of 5x. The image captured under these conditions can be referenced... Figure 64 The illustration shows an image captured by electronic device 4 at an equivalent focal length between 60mm and 300mm, in which the captured image includes a flock of birds flying in front of the church. Figure 64 The image captured has a small angle of view and depth of field, allowing the variable-focus telephoto imaging device 4a to be used for photographing moving targets. The drive mechanism 15d drives the lens carrier group 12d and the imaging lens 11d to perform rapid and continuous autofocus on the target, ensuring the target remains clear even when it moves away from the focus position. During image capture, the variable-focus telephoto imaging device 4a can further optically zoom on the subject to obtain a clearer image. The magnification of the imaging device is defined as the ratio of the maximum to the minimum focal length; for example, this imaging device has a magnification of 5x. The super-telephoto imaging device 4k has a maximum angle of view of 4 to 8 degrees, achieving an equivalent focal length between 400mm and 600mm. Images captured under these conditions can be referenced... Figure 65 The illustration shows an image captured by electronic device 4 at an equivalent focal length between 400mm and 600mm, in which the captured image includes an angel and a cross above a church spire. Figure 65The image has a narrower angle of view and depth of field, making the imaging lens 11d of the super telephoto imaging device 4k more prone to defocusing due to camera shake. Therefore, the drive mechanism 15d, while providing driving force to focus the imaging lens 11d of the super telephoto imaging device 4k on the target object, can simultaneously provide feedback force to correct camera shake, thus achieving optical image stabilization. Additionally, the imaging device 4g can acquire depth information of the image. The electronic device 4 described above includes multiple imaging devices 4k, 4a, 4b, 4c, 4d, 4e, 4f, and 4g as an example, but the number and configuration of the imaging devices are not intended to limit the invention. The equivalent focal length corresponding to the above imaging devices is a calculated estimate, and it may differ from the actual focal length due to the design of the imaging lens and the size of the electronic image sensor.

[0283] When the user photographs the subject OBJ, the electronic device 4 uses image capturing devices 4k, 4a, 4b, 4c, or 4d to capture the image, activates the flash module 42 for supplemental lighting, and uses the object distance information of the subject OBJ provided by the focus assist module 43 for fast focusing. Furthermore, the image signal processor 44 performs image optimization processing to further improve the image quality produced by the imaging lens. The focus assist module 43 can employ an infrared or laser focus assist system to achieve fast focusing.

[0284] In addition, the electronic device 4 can also take pictures using the image capturing devices 4e, 4f, or 4g. When the image capturing devices 4e, 4f, or 4g are taking pictures, an indicator light 4h can illuminate to remind the user that the electronic device 4 is taking pictures. The display device 45 can use a touch screen or a physical shooting button 451, and can perform image shooting and image processing in conjunction with the diverse functions of the image software processor 46. The image processed by the image software processor 46 can be displayed on the display device 45. The user can also replay previously captured images using the image playback button 452 on the display device 45, select a suitable image capturing device for shooting using the image capturing device switching button 453, and adjust the shooting conditions for the current shooting scene using the integrated menu button 454.

[0285] Furthermore, the electronic device 4 also includes a circuit board 47, and the circuit board 47 carries multiple electronic components 48. Image capturing devices 4k, 4a, 4b, 4c, 4d, 4e, 4f, and 4g are electrically connected to the electronic components 48 via connectors 471 on the circuit board 47. Each electronic component 48 may include a signal transmitting module 481, which can transmit images to other electronic devices or cloud storage. The signal transmitting module 481 may be a Wireless Fidelity (WiFi) module, a Bluetooth module, an infrared module, a network service module, or an integrated module of multiple such signal transmitting methods; this invention is not limited to this.

[0286] Electronic component 48 may also include storage unit 482, random access memory 483 for storing image signals, gyroscope 484, and position locator 485 for navigation or positioning of electronic device 4. In this embodiment, image signal processor 44, image software processor 46, and random access memory 483 are integrated into a single-chip system 49, but the invention is not limited to this configuration. In some other embodiments, electronic components may be integrated into the imaging device or disposed on one of multiple circuit boards. In addition, biometric sensor 50 can provide functions such as powering on and unlocking electronic device 4.

[0287] The imaging lens driving module of this invention is not limited to applications in smartphones. It can also be applied to mobile focusing systems as needed, offering both excellent aberration correction and good image quality. For example, the imaging lens driving module can be widely used in electronic devices such as 3D image capture, digital cameras, mobile devices, tablet computers, smart TVs, network monitoring equipment, dashcams, reversing cameras, multi-lens devices, recognition systems, motion-sensing game consoles, and wearable devices. The aforementioned electronic devices are merely illustrative examples of practical applications of this invention and do not limit the scope of application of the imaging lens driving module.

[0288] While the present invention has been disclosed above with reference to the foregoing embodiments, these embodiments are not intended to limit the invention. Any modifications and refinements made without departing from the spirit and scope of the invention are within the scope of patent protection of the present invention. For a description of the scope of protection defined in the appended claims, please refer to the appended claims.
