Please refer to FIGS. 1 and 2, the lens module 10 of the first embodiment of the present invention includes a lens barrel 12, a first element 14, a base 16, a housing 18, two guide rail structures 20, and four elastics 22 and two sets of drivers (not shown). Among them, the lens barrel 12 can move along a predetermined direction by the guide rail structures 20. The assembly of these components is described in detail below: The lens barrel 12 includes at least one lens, and the lens constitutes an optical axis (not shown). Specifically, the frame shape of the lens barrel 12 viewed from the object end (that is, along the optical axis) may be non-circular. As shown in FIG. 2, the base 16 includes a substrate 161 and two first sidewalls 163. The first sidewalls 163 are disposed on opposite sides of the substrate 161 and extend from the substrate 161 toward the first element 14, and Vertical to the substrate 161. Each first side wall 163 has a first hole 361 and a first mounting portion 363. The substrate 161 and the first side walls 163 form an accommodating space, and the accommodating space is used to accommodate the lens barrel 12. Each rail structure 20 includes a first shaft 201, a second shaft 203 and 一限位件205. The limiting member 205 has a first through hole 501 and a second through hole 503. The first through hole 501 and the second through hole 503 are perpendicular to each other. The first element 14 has two second side walls 141 and a second opening 143 oppositely arranged. The second opening 143 is located on an end surface of the first element 14 parallel to the substrate 161, and the second side walls 141 The end face extends toward the base 16. Each second side wall 141 has two second holes 411 and a second mounting portion 413. Each set of drivers includes a magnet (not shown) and a coil (not shown). In the first embodiment, the end of the housing 18 facing the base 16 (or parallel to the substrate 161) has a first opening 181.

The diameter of the first hole 361 is substantially equal to the diameter of the first shaft 201 (that is, the first hole 361 and the first shaft 201 are tightly fitted), and the diameter of the first hole 501 is larger than that of the first shaft 201 Diameter (ie loose fit between the first perforation 501 and the first shaft 201), the diameter of the second hole 411 is approximately equal to the diameter of the second shaft 203 (ie the second hole 411 and the second shaft 203 Between the second through hole 503 and the diameter of the second shaft 203 (that is, a loose fit between the second through hole 503 and the second shaft 203). Specifically, the first hole 361, the first hole 501, the second hole 411, and the second hole 503 are all circular. In short, if the diameter of the first hole 361, the first hole 501, the second hole 411, or the second hole 503 is about the same as the diameter of the first shaft 201 or the second shaft 203, there will be a tight Cooperate. If the diameter of the first hole 361, the first hole 501, the second hole 411, or the second hole 503 is larger than the diameter of the first shaft 201 or the second shaft 203, a loose fit will occur between the two.

To further explain, when the ratio of the diameter of the first hole 361, the first hole 501, the second hole 411, or the second hole 503 to the diameter of the first shaft 201 or the second shaft 203 is greater than 0.8, it produces a tight fit Effect, in the case of tight fit, the two remain fixed, and the tighter the ratio is when the ratio approaches 1, the first hole 361, the first hole 501, the second hole 411, or the second hole 503 When the ratio of the aperture diameter to the diameter of the first shaft 201 or the second shaft 203 is equal to or less than 0.8, it produces a loose fit effect, and in the case of a loose fit, the two can move relatively.

Please refer to Figures 3 and 4. During assembly, according to the aforementioned elastic configuration, one end of the first shaft 201 is fixed to the first hole 361, and the other end is movably penetrated through the first through hole 501 (that is, the limit The member 205 is sleeved on the first shaft 201). The second shaft 203 is movably penetrated through the second through hole 503 (that is, the stopper 205 is sleeved on the second shaft 203), and both ends of the second shaft 203 are fixed to the second holes 411, Therefore, the limiting members 205 are located between the first element 14 and the base 16. In this way, the first element 14 and the limiting members 205 can move relative to the base 16 along the axial direction of the first shaft 201 (that is, the direction perpendicular to the optical axis), and the movement range will be limited due to the limitation The bit member 205 is restricted to abut on the first side wall 163. The first element 14 can move relative to the limiting members 205 and the base 16 along the axial direction of the second shaft 203 (that is, parallel to the optical axis), and its moving range will be due to the second side wall 141 Restricted by the stopper 205. When the lens barrel 12 is disposed in the accommodating space, the first element 14 will be connected to an outer peripheral portion of the lens barrel 12, the first through hole 501 is perpendicular to the optical axis, and the second through hole 503 is parallel to the optical axis.

As shown in FIG. 3 again, the magnet systems of the two sets of drivers are respectively disposed on the two first mounting portions 363, and the coil systems of the two sets of drivers are respectively disposed on the two second mounting portions 413. Note that the coil and the magnet are opposite to each other, and the area of the coil is smaller than the area of the magnet. When current passes through the coil, the Lorentz Force of the magnet will act on the current flowing through the coil to drive the first element 14 to move relative to the base 16. In addition, each elastic member 22 has a first end 221 and a second end 223. The first end 221 is fixed to the base 16, and the second end 223 is fixed to the first element 14, so that it is moved The first element 14 can be reset and fixed relative to the base 16. In the first embodiment, the elastic members 22 are elongated and have a meandering portion, and the meandering portion is S-shaped. In the first embodiment, the magnetic pole distribution of the magnet of the first group of drivers is parallel to the first shaft 201, and the magnetic pole distribution of the magnet of the second group of drivers is parallel to the optical axis.

As also shown in FIG. 1, the assembled lens barrel 12, the first element 14, the base 16, The guide rail structures 20, the elastic members 22 and the drives are finally accommodated in the housing 18. It should be noted that the maximum diameter length of the first opening 181 is greater than the maximum diameter length of the corresponding portion of the lens barrel 12, and the maximum diameter length of the second opening 143 is greater than the maximum diameter length of the first opening 181. The maximum diameter length of the corresponding portion of the lens barrel 12, that is, the maximum diameter length of the second opening portion 143 has a ratio A with the external maximum diameter length of the corresponding portion of the lens barrel 12, and the maximum diameter length of the second opening portion 143 is the same as the first The maximum diameter length of the opening 181 has a ratio B, and the maximum diameter length of the first opening 181 has a ratio C with the external maximum diameter length of the corresponding portion of the lens barrel 12, the ratios A, B, and C are all greater than 1, and the ratio A, B and C show the relationship of A greater than B greater than C. Therefore, when the lens module 10 is assembled, the end surface of the lens barrel 12 facing the housing 18 will be exposed to the first opening 181 or the second opening 143.

In other words, the size of the first opening portion 181 is larger than the external size of the corresponding portion of the lens barrel 12, and the size of the second opening portion 143 is larger than the size of the first opening portion 181 and the external size of the corresponding portion of the lens barrel 12. Among them, one axis is perpendicular to the optical axis and the first shaft 201, the size of the first opening 181 is defined as the area of the opening at one end surface of the housing 18 perpendicular to the axis, and the second opening 143 is The dimension is defined as the area of the opening on the end surface of the first element 14 perpendicular to the axis, and the external dimension of the corresponding portion of the lens barrel 12 is defined as the area protruding from the end surface of the second opening portion 143.

When operating the lens module 10, the second group of drivers can drive the first element 14 to move the lens barrel 12 relative to the base 16 in a direction parallel to the optical axis. The first group of drivers can drive the first element 14 and The limiters 205 move relative to the base 16 in a direction perpendicular to the optical axis, thereby enabling the lens module 10 to realize the functions of optical image stabilization and auto focus. It shows that the first group of drivers is to realize optical anti-shake, and the second group of drivers is to achieve auto focus. Incidentally, the above operation process can also be understood as that the drives can drive the base 16 and the limiters 205 to move the lens barrel 12 moves relative to the first element 14 along a direction parallel to the optical axis, on the other hand, the base 16 can also be driven to move relative to the first element 14 and the limiting members 205 along a direction perpendicular to the optical axis .

It can be understood that, in addition to the aforementioned elastic configuration, the diameter of the first hole 361, the first hole 501, the second hole 411, or the second hole 503 is different from the diameter of the first shaft 201 or the second shaft 203, Three other elastic configurations can also be formed, such as: (1) The first shaft 201 and the first hole 361 are loosely fitted, and the first through hole 501 is a tight fit, and the second shaft 203 and the second hole There is a loose fit between 411 and a tight fit with the second perforation 503. (2) A tight fit between the first shaft 201 and the first hole 361, and a loose fit between the first through hole 501, and a loose fit between the second shaft 203 and the second hole 411, and the second There is a tight fit between the perforations 503. (3) A loose fit between the first shaft 201 and the first hole 361 and a tight fit with the first through hole 501, and a tight fit between the second shaft 203 and the second hole 411, with the second There is a loose fit between the perforations 503. It is worth noting that no matter which elastic configuration is adopted, the lens module 10 can be operated according to the foregoing description.

Note that even if the structure of the first element 14 and the base 16 are interchanged, the lens module 10 can still be operated according to the foregoing description.

Specifically, the second hole 411' has a long hole shape, and the first hole 361' has a circular shape that can tightly fit the first shaft 201'.

To further explain, when the ratio of the diameter of the first hole 361' and the diameter of the second hole 411' to the diameter of the first shaft 201' is greater than 0.8, it produces a tight fit effect. In the case of a tight fit, between the two Keep it fixed. The tighter the ratio is, the closer it is to 1. When the ratio of the diameter of the first hole 361', the second hole 411' to the diameter of the first shaft 201' is equal to or less than 0.8, it will produce The effect of loose fit, in the case of loose fit, the two can move relatively.

It should be particularly noted that the moving range of the first element 14' corresponds to the moving range of the first shaft 201' in the second hole 411'.

It is worth noting that even if each guide rail structure includes only one first shaft 201' (relatively, each first side wall 163' will also have only one first hole 361'), the lens module 10' can still conform to Follow the instructions above. In the second embodiment, the purpose of using two first shafts 201' is to make the first element 14' more stable when moved relative to the base 16'.
