Description

Technical Field

[0001] This invention relates to an imaging lens drive module, a camera module, and an electronic device, particularly an imaging lens drive module and a camera 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] However, in recent years, traditional optical lenses have struggled to meet the high optical quality demands of diversified electronic products. In particular, the stability of existing optical lenses during focusing may not satisfy the increasingly stringent market requirements for optical quality. Therefore, improving the mechanisms used to move optical lenses to meet the high specifications of today's electronic devices has become a crucial issue in the field. Summary of the Invention

[0004] In view of the above-mentioned problems, the present invention provides an imaging lens driving module, a camera module and an electronic device, which helps to improve the movement stability of the optical lens during the focusing process.

[0005] This invention provides an imaging lens driving module, comprising an imaging lens, a lens carrier, a base, a plurality of spheres, a focusing assembly, at least one buffer corresponding member, and at least one flexural buffer member. The imaging lens has an optical axis and is mounted on the lens carrier. The lens carrier includes a first guide rail and a second guide rail. The first guide rail extends in a direction parallel to the optical axis and has a second surface. The second guide rail extends in a direction parallel to the optical axis and has a fourth surface. The base is correspondingly disposed with the lens carrier and includes a third guide rail and a fourth guide rail. The third guide rail extends in a direction parallel to the optical axis and has a fifth surface and a sixth surface, the fifth and sixth surfaces being interconnected and forming an angle.

A sphere is disposed between the lens carrier and the base to provide the lens carrier with one degree of freedom of movement in a direction parallel to the optical axis. These spheres include at least one first sphere and at least one second sphere. The first sphere is disposed between a first guide rail and a third guide rail, and the second sphere is disposed between a second guide rail and a fourth guide rail. A focusing assembly is used to drive the lens carrier to move relative to the base in a direction parallel to the optical axis to achieve focusing of the imaging lens. A flexure buffer and a buffer counterpart are disposed opposite each other, and the flexure buffer is disposed on at least one of the lens carrier and the base.

The first sphere includes a first center, the second sphere includes a second center, and the first and second centers are connected in a plane perpendicular to the optical axis to form a first line, and the first line has a first midpoint. Preferably, when the focusing assembly drives the lens carrier to move relative to the base, a stop portion of the flexural buffer makes physical contact with the sphere, and the stop portion restricts the movement of the sphere within a specific range. When the focusing assembly does not drive the lens carrier, the flexural buffer and its corresponding buffer maintain a specific distance and do not make physical contact. The fifth surface is closer to the first midpoint than the sixth surface, and the seventh surface is closer to the first midpoint than the eighth surface. The second, fifth, and sixth surfaces each have a contact point with the first sphere, and the fourth, seventh, and eighth surfaces each have a contact point with the second sphere. The angle between the fifth and seventh surfaces is θ. 57 The angle between the sixth and eighth surfaces is θ. 68 It satisfies the following condition: |θ 57 -π|≤|θ 68 -π|。 Preferably, the fifth surface and the seventh surface are parallel to each other.

[0006] The present invention further provides an imaging lens driving module, comprising an imaging lens, a lens carrier, a base, a plurality of spheres, a focusing assembly, at least one buffer corresponding member, and at least one flexural buffer member.

These spheres include at least one first sphere and at least one second sphere. The first sphere is disposed between a first guide rail and a third guide rail, and the second sphere is disposed between a second guide rail and a fourth guide rail.

A flexure buffer and a buffer counterpart are disposed opposite each other, and the flexure buffer is disposed on at least one of the lens carrier and the base. The flexure buffer can flex to reduce the impact generated by the collision between the flexure buffer and the buffer counterpart when the lens carrier moves in a direction parallel to the optical axis. The first sphere includes a first center, the second sphere includes a second center, and the first and second centers are connected in a plane perpendicular to the optical axis to form a first line, and the first line has a first midpoint.

[0110] 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 to implement it accordingly. Based on the disclosure, claims, and drawings in this specification, any person skilled in the art can easily understand the related objects and advantages of the present invention. The following embodiments further illustrate the points of the present invention in detail, but are not intended to limit the scope of the present invention in any way.

[0111] The present invention provides an imaging lens driving module, which includes an imaging lens, a lens carrier, a base, a plurality of spheres, a focusing assembly, at least one buffer corresponding component, and at least one flexural buffer component.

[0112] An imaging lens is mounted on a lens carrier, and the lens carrier includes a first guide rail and a second guide rail extending in a direction parallel to the optical axis of the imaging lens. The first guide rail has a second surface, and the second guide rail has a fourth surface.

[0113] The base is correspondingly disposed to the lens carrier, and the base includes a third guide rail and a fourth guide rail extending in a direction parallel to the optical axis. The third guide rail has a fifth surface and a sixth surface, which are connected to each other and form an angle. The fourth guide rail has a seventh surface and an eighth surface, which are connected to each other and form an angle.

[0114] A sphere is disposed between the lens carrier and the base to provide the lens carrier with one degree of freedom of movement in a direction parallel to the optical axis. This sphere includes at least one first sphere and at least one second sphere. The first sphere is disposed between a first guide rail and a third guide rail, and the second sphere is disposed between a second guide rail and a fourth guide rail. That is, the first and third guide rails are arranged in pairs corresponding to each other, and the second and fourth guide rails are arranged in pairs corresponding to each other, which improves the collimation of the movement of these spheres in the direction parallel to the optical axis. The total number of these spheres is at least three. For example, in one embodiment of the invention, the number of first spheres is at least two, and the number of second spheres is at least one, but the invention is not limited thereto. In another embodiment of the invention, the number of first spheres is at least one, and the number of second spheres is at least two.

[0115] The focusing assembly is used to drive the lens carrier to move relative to the base in a direction parallel to the optical axis in order to achieve focusing of the imaging lens.

[0116] A flexural buffer and a corresponding buffer are disposed opposite each other, and the flexural buffer is disposed on at least one of the lens carrier and the base. The flexural buffer reduces the impact generated by the collision between the flexural buffer and the corresponding buffer when the lens carrier moves in a direction parallel to the optical axis. Specifically, the flexural buffer and the corresponding buffer flex after physical contact. This flexing can refer to one end of a single element being restrained while the other end bends due to a load, and the bend is recoverable when there is no load. The impact generated by the collision between the flexural buffer and the corresponding buffer prevents the imaging lens from focusing too quickly and reduces collisions between the lens carrier and the base during focusing, thus reducing the probability of abnormal noise. When the focusing assembly is not driving the lens carrier, the flexural buffer and the corresponding buffer maintain a specific distance and do not make physical contact. The flexural buffer can be made of plastic or metal, but this invention is not limited to these materials.

[0117] The first sphere contains a first center, and the second sphere contains a second center. The first and second centers are connected by a first line on a plane perpendicular to the optical axis. This first line has a first midpoint. (Please refer to...) Figure 11 It illustrates a schematic diagram of the first connecting line L1 and its first midpoint P1 according to the first embodiment of the present invention.

[0118] The fifth surface of the third guide rail is closer to the first midpoint than the sixth surface, and the seventh surface of the fourth guide rail is closer to the first midpoint than the eighth surface. Please refer to... Figure 14 It illustrates a schematic diagram showing the positional relationship between the first midpoint P1 of the first connecting line L1 and the fifth surface S5, the sixth surface S6, the seventh surface S7 and the eighth surface S8 according to the first embodiment of the present invention.

[0119] The second, fifth, and sixth surfaces each have a contact point with the first sphere, and the fourth, seventh, and eighth surfaces each have a contact point with the second sphere.

[0120] The angle between the fifth surface of the third guide rail and the seventh surface of the fourth guide rail is θ. 57 The angle between the sixth surface of the third guide rail and the eighth surface of the fourth guide rail is θ. 68 It satisfies the following condition: |θ 57 -π|≤|θ 68 -π|. Please refer to... Figure 14 It illustrates the parameter θ according to the first embodiment of the present invention. 57 and θ 68 A schematic diagram.

[0121] According to the imaging lens driving module disclosed in this invention, by having at least one contact point between the first sphere and the first and third guide rails, and at least one contact point between the second sphere and the second and fourth guide rails, the lens carrier can be provided with degrees of freedom to move in a direction parallel to the optical axis. Furthermore, by having an appropriate angle between the fifth and seventh surfaces, and an appropriate angle between the sixth and eighth surfaces, the stability of the mechanism can be improved, thereby increasing the manufacturing yield.

[0122] The flexure buffer may include a stop. When the focusing assembly drives the lens carrier to move relative to the base, the stop of the flexure buffer contacts the spheres, and the stop restricts the movement of the spheres within a specific range. In this way, the stop prevents the spheres from detaching from the guide rails (i.e., the first guide rail, the second guide rail, the third guide rail, and the fourth guide rail) during the movement of the lens carrier, thus maintaining stability in the movement of the lens carrier in a direction parallel to the optical axis.

[0123] The fifth and seventh surfaces can be parallel to each other. This improves the stability of the mechanism, thereby increasing the manufacturing yield.

[0124] The imaging lens driving module of the present invention may further include a housing, which is coupled to a base and together forms an internal space, and a lens carrier is disposed within the internal space. The lens carrier is movable within the internal space in a direction parallel to the optical axis.

[0125] The flexural buffer may further include an impact portion and a flexural portion, and the corresponding buffer may include a contact portion. The impact portion is used to physically contact the contact portion, the flexural portion is connected to the impact portion, and the flexural portion flexes after the impact portion and the contact portion collide. In this way, the impact portion collides with the contact portion, causing the flexural portion to flex, thereby mitigating the occurrence of abnormal noise caused by large-area impacts with components such as the base when the lens carrier moves in a direction parallel to the optical axis. The flexural portion may be recoverable.

[0126] The flexural buffer may be further disposed within the housing. In one embodiment, the flexural buffer is a separate element assembled with the housing, but the invention is not limited thereto. In another embodiment, the flexural buffer and the housing may be integrally formed.

[0127] In one embodiment of the invention, the buffer corresponding element may be disposed on the base. For example, in one embodiment, the buffer corresponding element is a separate component assembled with the base, but the invention is not limited thereto. In another embodiment, the buffer corresponding element is integrally formed with the base.

[0128] In another embodiment of the invention, the buffer corresponding element may be disposed on the lens carrier. For example, in one embodiment, the buffer corresponding element is a separate component assembled with the lens carrier, but the invention is not limited thereto. In another embodiment, the buffer corresponding element is integrally formed with the lens carrier.

[0129] In another embodiment of the invention, the buffer corresponding element may be disposed within the housing. For example, in one embodiment, the buffer corresponding element is a separate component assembled with the housing, but the invention is not limited thereto. In another embodiment, the buffer corresponding element is integrally formed with the housing.

[0130] The focusing assembly may include a magnet and a coil, with the coil and magnet correspondingly arranged, and one of the magnet and coil being coupled to the lens carrier. The coupling between the magnet and the lens carrier is implemented using a moving magnet drive configuration, while the coupling between the coil and the lens carrier is implemented using a moving coil drive configuration.

[0131] The first sphere may contain at least two first spheres, and the second sphere may contain at least two second spheres. Therefore, an appropriate number of spheres can improve the stability of the lens carrier's movement.

[0132] The optical axis and the first connecting line are connected in a plane perpendicular to the optical axis to form a second connecting line, which is orthogonal to and intersects the optical axis and the first connecting line. Furthermore, the intersection of the first and second connecting lines is an off-center point. Please refer to... Figure 11 It illustrates a schematic diagram of a first connecting line L1, a second connecting line L2, and an eccentric point P2 according to a first embodiment of the present invention.

[0133] In one embodiment of the invention, the off-center point may not coincide with the first midpoint of the first connecting line. This off-center design of the imaging lens allows the imaging lens drive module to be positioned at a corner of the electronic device, thereby improving the structural configuration margin of the electronic device. Please refer to... Figure 11 It illustrates a schematic diagram in which the eccentric point P2 does not coincide with the first midpoint P1 of the first connecting line L1 according to the first embodiment of the present invention.

[0134] In another embodiment of the invention, the eccentric point may coincide with the first midpoint of the first connecting line. Please refer to... Figure 15 It illustrates a schematic diagram in which the eccentric point P2 coincides with the first midpoint P1 of the first connecting line L1 in one exemplary embodiment of the present invention.

[0135] The first guide rail may further have a first surface, and the first surface of the first guide rail is connected to the second surface and forms an angle. The second guide rail may further have a third surface, and the third surface of the second guide rail is connected to the fourth surface and forms an angle. In this way, with a specific mechanism design, the stability of the spheres moving between the first, second, third, and fourth guide rails can be improved.

[0136] The first surface of the first guide rail and the fifth surface of the third guide rail can be parallel to each other. This, through a specific mechanism design, can improve the stability of the first sphere's movement between the first and third guide rails.

[0137] The third surface of the second guide rail and the seventh surface of the fourth guide rail can be parallel to each other. This, through a specific mechanism design, can improve the stability of the second sphere's movement between the second and fourth guide rails.

[0138] A gap may exist between the first surface of the first guide rail and the first sphere, and / or a gap may exist between the third surface of the second guide rail and the second sphere. That is, at least one of the gaps between the first surface of the first guide rail and the first sphere, and between the third surface of the second guide rail and the second sphere, may exist. This, under a specific mechanism design, can improve the stability of the movement of the spheres between the guide rails.

[0139] The angle between the fifth and sixth surfaces of the third guiding track is θ. 56 It can satisfy the following condition: π / 2≤θ 56 <π. This improves the manufacturability of the third guide rail and its corresponding first guide rail at specific angles. The following condition can also be satisfied: 98 degrees ≤ θ. 56 <π. Please refer to... Figure 13 It illustrates the parameter θ according to the first embodiment of the present invention. 56 A schematic diagram.

[0140] The angle between the seventh and eighth surfaces of the fourth guiding track is θ. 78 It can satisfy the following condition: π / 2≤θ 78 <π. This improves the manufacturability of the fourth guide rail and the corresponding second guide rail at specific angles. The following condition can also be satisfied: 98 degrees ≤ θ. 78 <π. Please refer to... Figure 13 It illustrates the parameter θ according to the first embodiment of the present invention. 78 A schematic diagram.

[0141] The imaging lens may include a reduction section, which is a portion of the imaging lens that is reduced toward the optical axis, causing the imaging lens to be non-circular in the direction surrounding the optical axis. In this way, the imaging lens may have a moderately chamfered structure, for example, but not limited to, depending on the needs of the mechanical design or optical imaging requirements.

[0142] The present invention provides a camera module comprising an electronic photosensitive element and the aforementioned imaging lens driving module, wherein the electronic photosensitive element is disposed on an imaging surface of the imaging lens driving module.

[0143] The present invention provides an electronic device comprising the aforementioned camera module.

[0144] The various technical features in the imaging lens driving module disclosed in this invention can be combined and configured to achieve the corresponding effects.
