[0002] As semiconductor processing technology continues to improve, the performance of electronic photosensitive components has increased, allowing pixels to achieve smaller sizes. Therefore, optical lenses with high imaging quality have become indispensable. Furthermore, with the rapid advancement of technology, the application range of mobile devices equipped with optical lenses has become wider, and the requirements for optical lenses have also become more diverse.

[0003] However, in recent years, traditional optical lenses have struggled to meet the high optical quality demands of the increasingly diverse electronic products. In particular, the stability of existing optical lenses during focusing may not be able to meet the increasingly stringent market demands for optical quality. Therefore, improving the mechanisms used to move optical lenses to meet the high standards required of today's electronic devices has become a key issue in the field. Utility Model Content

[0110] The following detailed description of the features and advantages of the present invention is intended to enable any person skilled in the art to understand the technical content of the present invention and implement it accordingly. Furthermore, based on the disclosure of this specification, the claims, and the accompanying drawings, any person skilled in the art can readily understand the relevant objectives and advantages of the present invention. The following examples further illustrate the concepts of the present invention but are not intended to limit the scope of the present invention in any way.

[0111] The utility model provides an imaging lens driving module, which comprises an imaging lens, a lens carrier, a base, a plurality of spheres, a focusing assembly, at least one buffer counterpart and at least one deflection buffer.

[0112] The 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, wherein the first guide rail has a second surface, and the second guide rail has a fourth surface.

[0113] The base is disposed corresponding to the lens carrier and includes a third guide rail and a fourth guide rail extending parallel to the optical axis. The third guide rail has a fifth surface and a sixth surface, the fifth and sixth surfaces being connected to form an angle, and the fourth guide rail has a seventh surface and an eighth surface, the seventh and eighth surfaces being connected to form an angle.

[0114] The spheres are disposed between the lens carrier and the base to provide the lens carrier with a 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 the first guide rail and the third guide rail, and the second sphere is disposed between the second guide rail and the fourth guide rail. In other words, the first guide rail and the third guide rail are disposed in pairs corresponding to each other, and the second guide rail and the fourth guide rail are disposed in pairs corresponding to each other, which can improve the alignment of these spheres moving in a direction parallel to the optical axis. The total number of these spheres is at least three. For example, in one embodiment of the present invention, the number of first spheres is at least two, and the number of second spheres is at least one, but the present invention is not limited thereto. In another embodiment of the present 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 along a direction parallel to the optical axis to achieve focusing of the imaging lens.

[0116] The flexure buffer and the buffer counterpart are arranged opposite to each other, and the flexure buffer is arranged on at least one of the lens carrier and the base. The flexure buffer can bend to reduce the impact caused by the collision between the flexure buffer and the buffer counterpart when the lens carrier moves in a direction parallel to the optical axis. Specifically, the flexure buffer and the buffer counterpart flex after physical contact. The flexure can refer to one end of the opposite ends of a single component being constrained, while the other end bends due to bearing a load, and the bent portion has recoverability when there is no load. The impact generated by the collision between the flexure buffer and the buffer counterpart prevents the imaging lens from moving too fast during the focusing process, and can reduce the collision between the lens carrier and the base and other components during the focusing process, thereby reducing the probability of generating abnormal noise. When the focusing assembly does not drive the lens carrier, the flexure buffer and the buffer counterpart maintain a specific distance and no physical contact. The flexure buffer can be made of plastic or metal, but the present invention is not limited thereto.

[0117] The first sphere includes a first center, the second sphere includes a second center, and the first center and the second center are connected on a plane perpendicular to the optical axis to form a first connecting line. The first connecting line has a first midpoint. Figure 11 , which shows a schematic diagram of the first connecting line L1 and the 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. Figure 14 , which shows a schematic diagram of 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 in the first embodiment of the present invention.

[0119] The second surface, the fifth surface and the sixth surface each have a contact point with the first sphere, and the fourth surface, the seventh surface and the eighth surface 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 , which satisfies the following conditions: |θ 57 -π|≤|θ 68 -π|. Please refer to Figure 14 , which shows the parameter θ according to the first embodiment of the present invention. 57 and θ 68 Schematic diagram of .

[0121] The imaging lens drive module disclosed in this invention provides the lens carrier with freedom of movement parallel to the optical axis by ensuring that the first sphere has at least one contact point with each of the first and third guide rails, and that the second sphere has at least one contact point with each of the second and fourth guide rails. Furthermore, by ensuring an appropriate angle between the fifth and seventh surfaces, and between the sixth and eighth surfaces, the structural stability is enhanced, thereby improving manufacturing yields.

[0122] The flexure dampener may include a stop. When the focusing assembly drives the lens carrier to move relative to the base, the stop of the flexure dampener physically contacts the spheres and restricts their movement within a specific range. This prevents the spheres from disengaging from the guide rails (i.e., the first, second, third, and fourth guide rails) during movement of the lens carrier, thereby maintaining stability during movement of the lens carrier parallel to the optical axis.

[0123] The fifth surface and the seventh surface can be parallel to each other, thereby improving the stability of the mechanism and the manufacturing qualification rate.

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

[0125] The deflection buffer may further include a striking portion and a flexing portion, and the corresponding buffer member may include a contact portion. The striking portion is configured to physically contact the contact portion, and the flexing portion is connected to the striking portion. The flexing portion flexes upon impact between the striking portion and the contact portion. This flexing portion deflects upon impact between the striking portion and the contact portion, thereby mitigating the noise generated by the lens carrier's large-area impact with components such as the base when the lens carrier moves parallel to the optical axis. The flexing portion may be resilient.

[0126] The deflection buffer can be further disposed on the housing. In one embodiment, the deflection buffer is a separate component assembled with the housing, but the present invention is not limited thereto. In another embodiment, the deflection buffer and the housing can be integrally formed.

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

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

[0129] In another embodiment of the present invention, the cushioning member may be disposed on the housing. For example, in one embodiment, the cushioning member is a separate component assembled with the housing, but the present invention is not limited thereto. In another embodiment, the cushioning member and the housing are integrally formed.

[0130] The focusing assembly may include a magnet and a coil, the coil and the magnet being disposed in correspondence with each other, and one of the magnet and the coil being coupled to the lens carrier. The coupling between the magnet and the lens carrier is implemented as a moving magnet drive configuration, while the coupling between the coil and the lens carrier is implemented as a moving coil drive configuration.

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

[0132] The optical axis and the first line are connected on a plane perpendicular to the optical axis to form a second line, wherein the second line is orthogonal to and intersects the optical axis and the first line. In addition, the intersection of the first line and the second line is an eccentric point. Figure 11 , which shows a schematic diagram of the first connecting line L1, the second connecting line L2 and the eccentric point P2 according to the first embodiment of the present invention.

[0133] In one embodiment of the present invention, the eccentric point and the first midpoint of the first connecting line may not coincide with each other. In this way, the eccentric design of the imaging lens allows the imaging lens driving module to be set at a corner position of the electronic device to improve the mechanical configuration margin of the electronic device. Figure 11 , which shows a schematic diagram of a first embodiment of the present invention in which the eccentric point P2 and the first midpoint P1 of the first connecting line L1 do not coincide with each other.

[0134] In another embodiment of the present invention, the eccentric point and the first midpoint of the first connecting line may coincide with each other. Figure 15 , which shows a schematic diagram of an eccentric point P2 coinciding with a first midpoint P1 of a first connecting line L1 according to one exemplary embodiment of the present invention.

[0135] The first guide rail may further include a first surface, wherein the first and second surfaces of the first guide rail are connected to each other and form an angle. The second guide rail may further include a third surface, wherein the third and fourth surfaces of the second guide rail are connected to each other and form an angle. This, with a specific mechanical design, can improve the stability of the balls as they move between the first, second, third, and fourth guide rails.

[0136] The first surface of the first guide track and the fifth surface of the third guide track can be parallel to each other. In this way, under a specific mechanism design, the stability of the first ball moving between the first guide track and the third guide track can be improved.

[0137] The third surface of the second guide track and the seventh surface of the fourth guide track can be parallel to each other. In this way, under a specific mechanism design, the stability of the second ball moving between the second guide track and the fourth guide track can be improved.

[0138] A gap may exist between the first surface of the first guide rail and the first ball, and / or a gap may exist between the third surface of the second guide rail and the second ball. In other words, a gap may exist between at least one of the first surface of the first guide rail and the first ball, and between the third surface of the second guide rail and the second ball. This, with specific mechanical design, can improve the stability of the balls as they move between the guide rails.

[0139] The angle between the fifth surface and the sixth surface of the third guide rail is θ 56 , which can satisfy the following conditions: π / 2≤θ 56 <π. Thus, at a specific angle, the manufacturability of the third guide rail and the corresponding first guide rail can be improved. The following conditions can also be met: 98 degrees ≤ θ 56 <π. Please refer to Figure 13 , which shows the parameter θ according to the first embodiment of the present invention. 56 Schematic diagram of .

[0140] The angle between the seventh surface and the eighth surface of the fourth guide rail is θ 78 , which can satisfy the following conditions: π / 2≤θ 78 <π. Thus, at a specific angle, the manufacturability of the fourth guide rail and the corresponding second guide rail can be improved. The following conditions can also be met: 98 degrees ≤ θ 78 <π. Please refer to Figure 13 , which shows the parameter θ according to the first embodiment of the present invention. 78 Schematic diagram of .

[0141] The imaging lens may include a tapered portion, where the tapered portion is tapered from a portion of the imaging lens toward the optical axis, resulting in the imaging lens having a non-circular shape along the direction around the optical axis. This allows the imaging lens to have a suitable trimmed edge structure, for example, but not limited to, to meet mechanical design requirements or optical imaging needs.

[0142] The utility model provides a camera module, which includes an electronic photosensitive element and the aforementioned imaging lens driving module, wherein the electronic photosensitive element is arranged on an imaging surface of the imaging lens driving module.

[0143] The utility model provides an electronic device, which includes the aforementioned camera module.

[0144] The various technical features of the imaging lens driving module disclosed in the present invention can be configured in combination to achieve corresponding effects.

[0145] Based on the above implementation manner, specific embodiments are presented below and described in detail with reference to the accompanying drawings.
