[0095] The present disclosure provides an imaging lens driving module, which includes an imaging lens group, a carrier element, and a driving mechanism. The imaging lens group has an optical axis. The carrier element is configured to dispose the imaging lens group and includes an assembly structure, wherein the assembly structure is disposed on an outer surface of the carrier element and extends in a direction away from the optical axis. The driving mechanism is configured to drive the carrier element to move in a direction parallel to the optical axis and includes at least one coil set and at least two magnets. The coil set is disposed on the assembly structure of the carrier element and includes a bottom coil and a top coil, wherein the bottom coil is wound around the assembly structure and in physical contact with the assembly structure; the top coil is stacked on the bottom coil and is farther away from the assembly structure than the bottom coil, and the top coil overlaps the bottom coil in the direction parallel to the optical axis. The magnets are respectively disposed corresponding to the coil set. Specifically, the present disclosure is configured to simultaneously and in the same winding direction wind the assembly structure with the same wire, thereby generating the coil set disposed opposite to each other. Therefore, compared with the coil set generated by simultaneously winding the assembly structure in the prior art, the imaging lens driving module of the present disclosure can save the cycle time of the product.

[0096] In detail, the carrier element can be a coil holder, a lens carrier, or an element combining the functions of the above two, but is not limited thereto. Furthermore, the magnets can interact with the coil set to generate driving magnetic force, so that the driving mechanism drives the carrier element to move in the direction parallel to the optical axis.

[0097] The driving mechanism can further include at least one elastic element, and the elastic element is coupled to the carrier element. Further, the number of elastic elements can be two, and can include an upper elastic element and a lower elastic element, wherein the upper elastic element is disposed on the object side of the imaging lens group, and the lower elastic element is disposed on the image side of the imaging lens group and is disposed opposite to the upper elastic element. In this way, the driving stroke range of the driving mechanism can be defined.

[0098] The coil set can have only two wire terminals, and the wire terminals are respectively disposed on the top coil. Specifically, the wire terminal can be an end region of the wire wound around the carrier element, the wire terminal can be in a disconnected form, and one end of the wire terminal is connected to the top coil, and the other end of the wire terminal is exposed to the air.

[0099] The wire terminals of the top coil can be electrically connected to the elastic element of the driving mechanism. The electrical connection can be achieved by welding or dispensing, but is not limited thereto. In this way, the wire terminals can be electrically connected to other elements to improve the design margin of the product workstation. Specifically, the welding workstation or dispensing workstation can be adjusted in terms of the order of execution relative to other workstations during the planning and design phase.

[0100] The coil set of the driving mechanism can be an assembly structure in which a wire is wound around the carrier element from the wire terminal of the bottom coil to the wire terminal of the top coil. Specifically, the bottom coil is composed of a wire, and the top coil has a wire terminal, so the coil set is composed of the same wire. By winding the same wire to form the coil set at the same time, the manufacturing process can be reduced, and the product cycle time can be reduced.

[0101] The carrier element can further include at least two columnar structures. The columnar structures are arranged on the outer surface of the carrier element and extend in the direction parallel to the optical axis and toward the image side of the imaging lens group. Specifically, the columnar structures can be integrally formed with the carrier element, but are not limited thereto. By integrally forming the columnar structures with the carrier element, the assembly tolerance between the elements can be reduced.

[0102] The wire terminals of the top coil can be individually wound around the columnar structures and in physical contact therewith. Specifically, the wire terminals are wound around the columnar structures to provide the wire tension required for fixing the coil set. In this way, the wire can be prevented from coming loose from the carrier element to improve the yield.

[0103] The lower elastic element can include an inner side portion, an outer side portion, and an elastic connecting portion. The inner side portion is coupled to the carrier element, the outer side portion is coupled to a base of the imaging lens driving module, and the elastic connecting portion connects the inner side portion and the outer side portion. In this way, the lower elastic element can have a better coupling position to ensure the driving efficiency of the driving mechanism.

[0104] The wire terminals of the top coil can be electrically connected to the lower elastic element other than the outer side portion. In this way, a better electrical connection area position can be achieved, and the miniaturization of the imaging lens driving module can be facilitated.

[0105] The carrier element can further include at least one abutting portion. The abutting portion and the assembly structure are alternately arranged in a circumferential direction around the optical axis. In this way, the space utilization in the imaging lens driving module can be improved.

[0106] The connecting wire of the coil set can be in physical contact with a wire branching point of the abutting portion of the carrier element. Through the wire branching point, the automatic optical detection process can be more accurate and fast, and the length of the wire constituting the coil set can be effectively controlled to reduce production costs.

[0107] Alternatively, the bottom coil of the coil set can have only two wire ends, wherein the coil set can further include a connecting wire, and the connecting wire connects the wire ends of the bottom coil to keep the bottom coil electrically connected. In particular, the connecting wire can be a part of the coil set, but is not limited thereto. In this way, the coil set can be formed by a continuous wire.

[0108] The coil set can further include a first coil and a second coil, wherein the first coil is disposed on the assembly structure of the carrier element, and the second coil is disposed on the assembly structure of the carrier element and opposite to the first coil. Further, the first coil and the second coil can include the bottom coil and the top coil, respectively, and the winding direction of the first coil is the same as that of the second coil when viewed from the first coil toward the second coil. In particular, the winding direction is the same as clockwise or counterclockwise. By the same winding direction, the winding process can be simplified, thereby reducing the time cost.

[0109] The first coil and the second coil can be formed by two wires to keep the first coil and the second coil electrically separated. In detail, by winding the assembly structure with different wires to form the first coil and the second coil, two electrically separated first coil and second coil can be generated to adjust the tilt degree of the imaging lens set. In this way, the electrically separated first coil and second coil can be controlled separately to further optimize the imaging quality.

[0110] The lower elastic element can include four elastic pieces electrically separated from each other. In particular, the elastic pieces are suitable for mass production, easy to assemble, and can effectively reduce the volume of the imaging lens driving module. Furthermore, the elastic pieces can be electrically connected to the wire terminal and the wire end of the first coil and the wire terminal and the wire end of the second coil, respectively. In detail, the elastic pieces can be further electrically connected to the wire terminal of the top coil of the first coil, the wire end of the bottom coil, the wire terminal of the top coil of the second coil, and the wire end of the bottom coil, respectively. In this way, the elastic pieces electrically separated from each other can be kept, wherein the elastic pieces are divided into two pieces as a group and can be electrically connected to the first coil and the second coil, respectively, to improve the accuracy of adjusting the tilt degree of the imaging lens set.

[0111] The coil set includes M coil sets and N wire terminals, which can satisfy the following conditions: N / 2 = M; and 2 ≤ N ≤ 10. In this way, a suitable range of the number of coil sets can be obtained.

[0112] The technical features of the imaging lens driving module described above can be combined to achieve the corresponding effects.

[0113] The present disclosure provides an electronic device including the imaging lens driving module described above.

[0114] Based on the above implementation methods, specific embodiments are presented below and described in detail with reference to the accompanying drawings.

[0117] The carrier element 150 is used to configure the imaging lens group 140 and includes an assembly structure 151, at least two columnar structures 152, and at least one support portion 153. The assembly structure 151 is disposed on the outer surface of the carrier element 150 and extends in a direction away from the optical axis X. The columnar structures 152 are disposed on the outer surface of the carrier element 150 and extend in a direction parallel to the optical axis X and toward the image side of the imaging lens group 140. The support portion 153 and the assembly structure 151 are alternately arranged in a circumferential direction around the optical axis X. Specifically, the carrier element 150 may be a coil holder, a lens carrier, or an element combining the functions of both. The columnar structures 152 may be integrally formed with the carrier element 150, but are not limited to the above. By integrally forming the columnar structures 152 with the carrier element 150, assembly tolerances between components can be reduced. Furthermore, by alternately arranging the support portion 153 and the assembly structure 151 along the circumferential direction surrounding the optical axis X, the space utilization rate within the imaging lens drive module 100 can be improved.

[0118] The driving mechanism is used to drive the carrier element 150 to move along the direction of the optical axis X, and comprises at least one elastic element, at least one coil set 160, and at least two magnets 170. The elastic element is coupled with the carrier element 150, and the number of the elastic element can be two, and comprises an upper elastic element 130 and a lower elastic element 180, wherein the upper elastic element 130 is arranged on the object side of the imaging lens set 140, the lower elastic element 180 is arranged on the image side of the imaging lens set 140, and is arranged opposite to the upper elastic element 130. In this way, the driving stroke range of the driving mechanism can be defined. The coil set 160 is arranged on the assembly structure 151 of the carrier element 150. The magnets 170 are arranged correspondingly with the coil set 160, and the magnets 170 can interact with the coil set 160 respectively to generate driving magnetic force, so that the driving mechanism drives the carrier element 150 to move along the direction of the optical axis X. It is worth mentioning that the gasket 120 can be used to adjust the relative position of the upper elastic element 130 in the housing 110.

[0119] The lower elastic element 180 comprises an inner side 181, an outer side 182, and an elastic connecting part 183, wherein the inner side 181 is coupled with the carrier element 150, the outer side 182 is coupled with the base 190 of the imaging lens driving module 100, and the elastic connecting part 183 connects the inner side 181 and the outer side 182. In this way, the lower elastic element 180 can have a better coupling position to ensure the driving efficiency of the driving mechanism.

By FIG. 1C to FIG. 1LThe coil set 160 includes a bottom coil 163 and a top coil 164. The bottom coil 163 is wound around the assembly structure 151 and contacts the assembly structure 151. The top coil 164 is stacked on the bottom coil 163 in a stacking direction D2, is farther away from the assembly structure 151 than the bottom coil 163, and overlaps the bottom coil 163 in a direction parallel to the optical axis X.

[0121] The coil set 160 has only two wire terminals 165, which are respectively arranged on the top coil 164. The wire terminals 165 of the top coil 164 are electrically connected to the elastic element of the driving mechanism. The electrical connection can be achieved by welding or dispensing, but is not limited thereto. FIG. 1C In the first embodiment, the wire terminals 165 of the top coil 164 are electrically connected to the lower elastic element 180 of the driving mechanism. The wire terminals 165 of the top coil 164 are connected to the lower elastic element 180 through the dispensing of the electrical connection part C. In this way, the wire terminals 165 can be electrically connected to other elements to improve the design margin of the product work station.

[0122] Further, the wire terminals 165 of the top coil 164 are electrically connected to the lower elastic element 180 except the outer side part 182. That is, the wire terminals 165 of the top coil 164 are electrically connected to the inner side part 181 and the elastic connection part 183 of the lower elastic element 180, but are not limited thereto. In this way, a better electrical connection area position can be achieved, which is helpful for the miniaturization of the imaging lens driving module 100.

[0123] In the first embodiment, the wire terminals 165 of the top coil 164 are electrically connected to the lower elastic element 180 of the driving mechanism. The wire terminals 165 of the top coil 164 are connected to the lower elastic element 180 through the dispensing of the electrical connection part C. In this way, the wire terminals 165 can be electrically connected to other elements to improve the design margin of the product work station. FIG. 1E 、 FIG. 1F and FIG. 1L The coil set 160 of the driving mechanism can be composed of a wire that is wound around the assembly structure 151 of the carrier element 150 in the wire winding direction D1 from the bottom coil 163 to the wire terminal 165 of the top coil 164. In detail, the bottom coil 163 is composed of a wire, and the top coil 164 has the wire terminal 165. Therefore, the coil set 160 is composed of the same wire.

FIG. 1C and FIG. 1EIt is understood that the lead wire terminals 165 of the top coil 164 can each be wound around the columnar structure 152 and in contact with it.
