Abstract
Description
Technical Field
[0001] The present invention relates to the field of lens driving technology, and in particular to a lens module and electronic equipment. Background Art
[0002] With the rapid development of imaging technology, the industry's demand for camera lenses is increasing. Consequently, camera lenses integrating features such as variable aperture, autofocus, and optical image stabilization have emerged. These multifunctional lenses aim to meet a wider range of user needs and enhance competitiveness. However, with this increased functionality, camera lenses are becoming increasingly bulky and lack operational stability, impacting the user experience. Therefore, the industry urgently needs a camera lens that is both compact and highly stable. Summary of the Invention
[0003] Based on this, it is necessary to provide a lens module and electronic equipment to achieve the effects of small size and high operating stability.
[0004] A lens module includes a base, a drive seat, a lens structure and a support assembly, wherein the support assembly includes a first elastic support element and a second elastic support element, the first elastic support element connects the base and the drive seat so that the drive seat can be suspended on the base, and the second elastic support element connects the drive seat and the lens structure so that the lens structure can be suspended on the drive seat.
[0005] In the lens module described above, the first elastic support element supports the drive seat. Compared to a suspension wire support method, the first elastic support element has a stronger bearing capacity. With the support of the first elastic support element, the drive seat is less likely to sink, thereby improving the operational stability of the lens module. Simultaneously, the second elastic support element supports and limits the lens structure, also improving the operational stability of the lens module.
[0006] In one embodiment, the lens module further includes a first electronic component disposed on the drive seat and a second electronic component disposed on the base, wherein the first electronic component and the second electronic component are electrically connected via the first elastic support element and the second elastic support element. Thus, while the provision of the first and second elastic support elements improves the operational stability of the lens module, the first and second elastic support elements also function as circuit connections, thereby reducing the number of components in the lens module and simplifying the setup process.
[0007] In one embodiment, the support assembly includes a plurality of first elastic support elements and a plurality of second elastic support elements. The plurality of first elastic support elements are spaced apart along the circumference of the drive base. The second elastic support element corresponds to at least one of the first elastic support elements, and each second elastic support element is connected to a corresponding first elastic support element. The second elastic support elements are connected to the first elastic support elements in a one-to-one correspondence, so that the second elastic support elements and the first elastic support elements can also be mutually limited, which is beneficial to improving the operational stability and structural strength of the lens module.
[0008] In one embodiment, the first elastic support element includes a first spring, a second spring, a third spring, and a fourth spring. Four second elastic support elements are provided, the first spring, the second spring, the third spring, and the fourth spring being spaced apart circumferentially around the drive base. The four second elastic support elements are connected to the first spring, the second spring, the third spring, and the fourth spring in a one-to-one correspondence. The four first elastic support elements can provide stable support for the four corners of the drive base, thereby further improving the stability of the lens module during optical image stabilization.
[0009] In one embodiment, the first elastic support element further includes a fifth spring, a sixth spring, a seventh spring, and an eighth spring, wherein the fifth spring, the sixth spring, the seventh spring, and the eighth spring connect the base and the drive base, and the first spring and the seventh spring are adjacent, the second spring and the eighth spring are adjacent, the third spring and the fifth spring are adjacent, and the fourth spring and the sixth spring are adjacent. The eight first elastic support elements are adjacent to each other and distributed around the drive base, which can provide stronger support for the drive base, thereby further improving the operational stability of the lens module during optical image stabilization.
[0010] In one embodiment, the lens module further includes a first magnet, a coil, and a focus control element, wherein the coil at least partially bypasses the first magnet;
[0011] The focus control element, the first reed, the elastic limiting element connected to the first reed, the coil, and the focus control element are electrically connected in sequence to form a circuit. This circuit, formed by the focus control element, the first reed, the elastic limiting element, and the coil, allows the circuit circuit for the focus control element to drive the first magnet to be combined with the supporting structure of the first reed and the elastic limiting element. This not only achieves circuit connection and structural support, but also simplifies the number of components and structural design, thereby reducing the size of the lens module.
[0012] In one embodiment, the lens module further includes an anti-shake drive assembly, and two first magnets are provided, and the two first magnets are respectively provided on opposite sides of the lens structure;
[0013] Furthermore, the first magnet includes a first magnetic portion, a second magnetic portion, and a third magnetic portion. The first and second magnetic portions are stacked in the axial direction of the lens module. The third magnetic portion is located on the side of the second magnetic portion facing away from the lens structure, forming a stepped surface with the first magnetic portion. The provision of the stepped surface reduces the weight and volume of the first magnet by one-fourth compared to conventional square magnets, thereby ensuring the driving effect on the lens structure while also reducing the volume and weight of the lens module.
[0014] In one embodiment, the lens module further includes a first wiring electrically connecting the first reed and the focus control element, with a portion of the first wiring disposed on the stepped surface. The design of the first wiring disposed on the stepped surface allows the structural design of the first magnet to provide space for the first wiring, thereby saving wiring space for the first wiring and facilitating a reduction in the size of the lens module.
[0015] In one embodiment, the lens module further includes an anti-shake control element and an aperture control element. The third, fourth, fifth, and sixth springs are all electrically connected to the focus control element and the aperture control element. The third and fourth springs are also electrically connected to the anti-shake control element, so that the focus control element, the aperture control element, and the anti-shake control element are connected in parallel. The springs connect the aperture control element, the focus control element, and the anti-shake control element in parallel, providing support while further integrating the lens module's circuitry. This helps to further improve the integration of the lens module structure, simplify the number of components in the lens module, and thus help to reduce the size of the lens module.
[0016] In one embodiment, the lens module further includes a second wiring and a circuit board. The second wiring is housed within the drive base, electrically connected to the focus control element and exposed on the outer surface of the drive base. The circuit board is electrically connected to the aperture control element and fixedly mounted on the outer surface of the drive base. The third spring, the circuit board, and the second wiring are welded to the outer surface of the drive base. Thus, while the spring improves the circuit integration, it also helps to enhance the structural strength and connection stability of the lens module.
[0017] In one embodiment, the lens module further includes an anti-shake circuit board provided on the base, the first reed and the second reed are electrically connected to the anti-shake circuit board, the base is provided with a receiving groove, the anti-shake control element is received in the receiving groove and electrically connected to the anti-shake circuit board; and / or,
[0018] The lens module further includes an anti-shake circuit board provided on the base, the base is provided with a welding groove, and the ends of the first reed and the second reed are welded to the anti-shake circuit board in the welding groove; and / or,
[0019] The base is provided with a foot slot. The lens module further includes an anti-shake circuit board mounted on the base. The anti-shake circuit board has connecting feet protruding from the direction away from the drive base. The connecting feet are received in the foot slot. The grooves in the base provide space for the anti-shake control element and the connecting feet, and / or provide space for welding the first elastic support element and the anti-shake circuit board. This helps to reduce the axial dimension of the lens module, thereby further reducing the volume of the lens module.
[0020] An electronic device includes a fixing member and a lens module as described in any of the above embodiments, wherein the lens module is disposed on the fixing member. When the lens module is used in the electronic device, the lens module has good operating stability, which is conducive to improving the performance of the electronic device.

[0038] See Figure 1 、 Figure 2 and Figure 3 In some embodiments of the present application, a lens module 10 is provided. The lens module 10 has an imaging function. For example, the lens module 10 may include a lens structure 11 and a photosensitive element. The lens structure 11 includes a lens barrel and a lens assembly housed therein. Light from the object side is conditioned by the lens structure 11 before reaching the photosensitive element to form an image.
[0039] The lens module 10 may also be integrated with a variety of components to achieve diversified functions. For example, in some embodiments, the lens module 10 includes a variable aperture 12 and an aperture control element 13. The aperture control element 13 can control the aperture of the variable aperture 12 to enlarge or reduce, thereby adjusting the aperture size of the lens module 10, so that the lens module 10 can adapt to environments with different light intensities. Figure 4 As shown, in some embodiments, the lens module 10 may include a focus control element 14 and a first magnet 170. The focus control element 14 can control the first magnet 170 to drive the lens structure 11 to move along the axial direction of the lens module 10, thereby realizing the autofocus function of the lens module 10, so that the lens module 10 can adapt to subjects with different object distance ranges. It should be noted that the axial direction of the lens module 10 can be understood as the optical axis of the lens group in the lens structure 11. Figure 5 and Figure 6 As shown, in some embodiments, the lens module 10 may further include an anti-shake control element 15 and a support assembly. The anti-shake control element 15 drives the lens structure 11 to swing to achieve an optical anti-shake function, and the support assembly can effectively support and limit the lens structure 11 when the lens structure 11 swings, thereby improving the stability of the lens structure 11 during the swinging process, so that the lens module 10 can also have good imaging quality in a shaking environment.
[0040] Further, combined with Figures 1-6As shown, in some embodiments, the lens module 10 further includes a base 18 and a driving base 19, the anti-shake control element 15 is disposed on the base 18, the focus control element 14 is disposed in the driving base 19, and the driving base 19 can be suspended on the base 18 through a support assembly. Specifically, in some embodiments, the first elastic support element of the support assembly includes a first spring 160, a second spring 162, a third spring 163, and a fourth spring 164. The two ends of the first spring 160 are respectively connected to the base 18 and the driving base 19, the two ends of the second spring 162 are respectively connected to the base 18 and the driving base 19, the two ends of the third spring 163 are respectively connected to the base 18 and the driving base 19, and the two ends of the fourth spring 164 are also respectively connected to the base 18 and the driving base 19. The first spring 160, the second spring 162, the third spring 163, and the fourth spring 164 together enable the driving base 19 to be suspended on the base 18. It will be appreciated that in some embodiments, the lens structure 11 is connected to the drive base 19, and the anti-shake control element 15 can drive the drive base 19 to move to achieve the optical image stabilization function of the lens structure 11. Any one or more of the first spring 160, the second spring 162, the third spring 163, and the fourth spring 164 can vibrate with the drive base 19. The support and limiting effect of the first elastic support element on the drive base 19 can enhance the stability of the drive base 19 during the vibration process. The first spring 160, the second spring 162, the third spring 163, and the fourth spring 164 are spaced apart along the circumference of the drive base 19 to support the drive base 19 at four locations along the circumference. In some embodiments, one end of the first spring 160 is electrically connected to the output of the focus control element 14, and the other end is electrically connected to the anti-shake control element 15. The second spring 162 has one end electrically connected to the output of the focus control element 14, and the other end is electrically connected to the anti-shake control element 15. In other words, while the first spring 160 and the first spring 160 realize the supporting function of the drive seat 19, they can also provide line connection for the focus control element 14 and the anti-shake control element 15, thereby improving the component integration of the lens module 10 and reducing the number of components of the lens module 10.
[0041] The lens module 10 described above supports the drive base 19 via four first elastic support elements. Compared to traditional suspension wire supports, the first elastic support elements have a stronger bearing capacity, making the drive base 19 less likely to sink during vibration, thereby effectively improving the operational stability of the lens module 10. Furthermore, the first elastic support elements are also conductive. For example, the first elastic support elements may include a conductive material such as copper. While supporting the drive base 19, the first elastic support elements also integrate the connection circuits of the focus control element 14 and the anti-shake control element 15, thereby reducing the number of components in the lens module 10, simplifying the structural design of the lens module 10, and facilitating a reduction in the volume of the lens module 10.
[0042] Of course, the present application can also provide a conductive layer on the first elastic support element, or provide a wire running along the first elastic support element to electrically connect the first elastic support element to the focus control element 14, the anti-shake control element 15, and other components. In addition, the lens module 10 can also be provided with three first elastic support elements, which are arranged at intervals along the axial direction of the drive base 19 and can also provide support for the drive base 19.
[0043] Combine Figure 3 and Figure 7 As shown, in some embodiments, two first magnets 170 are provided, and the lens module 10 further includes a second magnet 175. The two first magnets 170 and the second magnet 175 together constitute an anti-shake drive assembly. Under the control of the anti-shake control element 15, the anti-shake drive assembly can drive the drive base 19 to swing, thereby achieving the optical image stabilization function of the lens structure 11. Specifically, in some embodiments, the two first magnets 170 are respectively provided on opposite sides of the lens structure 11. The first magnets 170 are used to drive the lens structure 11 to move along the circumference and / or the first direction of the lens module 10. The second magnet 175 is provided on a side of the lens structure 11 different from the first magnets 170. For example, the second magnet 175 extends along the first direction, while the first magnet 170 extends along the second direction, with the extension directions of the first magnet 170 and the second magnet 175 being perpendicular. The second magnet 175 is used to drive the lens structure 11 to move along the second direction, where the first direction and the second direction are two mutually perpendicular directions on a virtual plane perpendicular to the axial direction of the lens module 10. The cooperation between the first magnet 170 and the second magnet 175 can realize the movement of the lens structure 11 in the three-dimensional coordinate system, thereby realizing the optical image stabilization function.
[0044] It is understandable that the provision of two first magnets 170 to synchronously drive the lens structure 11 to move along the axial direction and / or the first direction of the lens module 10 can provide sufficient driving force for the lens structure 11, thereby preventing the lens structure 11 from being too heavy and affecting the driving effect, thereby enabling the lens module 10 to have good operating stability even when configured with a large lens. Furthermore, in some embodiments, the first magnet 170 driving the lens structure 11 to move along the axial direction of the lens module 10 can also realize the autofocus function of the lens structure 11, thereby combining the optical image stabilization drive element with the autofocus drive element, and making full use of the magnetic field provided by the first magnet 170, which is conducive to improving the integration of the components of the lens module 10, thereby further reducing the volume of the lens module 10.
[0045] In some embodiments, the first magnet 170 includes a first magnetic portion 171, a second magnetic portion 172, and a third magnetic portion 173, wherein the first magnetic portion 171 and the second magnetic portion 172 are stacked in the axial direction of the lens module 10, and the third magnetic portion 173 is provided on the side of the second magnetic portion 172 facing away from the lens structure 11 to form a stepped surface 174 with the first magnetic portion 171. The formation of the stepped surface 174 can reduce the weight and volume of the first magnet 170, so that the weight and volume of the first magnet 170 are reduced by one-fourth compared to traditional square magnets. Therefore, while providing two first magnets 170 to ensure the stability of the lens structure 11 drive, it is also beneficial to further reduce the volume and weight of the lens module 10.
[0046] In some embodiments, the end of the first magnetic portion 171 close to the lens structure 11 is an S pole, and the end away from the lens structure 11 is an N pole. The end of the second magnetic portion 172 close to the lens structure 11 is an N pole, and the end away from the lens structure 11 is an S pole. The end of the third magnetic portion 173 close to the lens structure 11 is an N pole, and the end away from the lens structure 11 is an S pole. The first magnetic portion 171 and the second magnetic portion 172 are fixedly connected, and the second magnetic portion 172 and the third magnetic portion 173 are fixedly connected. In some embodiments, the two first magnets 170 are arranged in mirror symmetry with the plane passing through the axis of the lens structure 11 as a reference plane.
[0047] refer to Figure 3 and Figure 4 As shown, in some embodiments, the lens module 10 further includes a first wiring 21, the two ends of the first wiring 21 being electrically connected to the first reed 160 and the focus control element 14, thereby electrically connecting the first reed 160 and the focus control element 14. The portion of the first wiring 21 corresponding to the position of the first magnet 170 is provided on the step surface 174, for example, extending along the step surface 174. This arrangement can cleverly combine the small volume design of the first magnet 170 and the circuit design of the first wiring 21, so that the portion of the first wiring 21 corresponding to the first magnet 170 is accommodated in the space formed by the first magnetic portion 171 and the third magnetic portion 173. The first wiring 21 does not need to be routed from the outside of the first magnet 170, thereby not increasing the radial dimension of the lens module 10, which is conducive to further reducing the volume of the lens module 10. It is understandable that when the two first magnets 170 are symmetrically arranged, two first lines 21 can also be provided, the two first lines 21 respectively connecting the first reed 161 and the second reed 162, and the two first lines 21 are arranged on the step surfaces 174 of the two first magnets 170 in a one-to-one correspondence.
[0048] In some embodiments, the drive seat 19 is roughly square, and the first spring 160, the second spring 162, the third spring 163 and the fourth spring 164 are respectively connected to the four corners of the drive seat 19. For example, the four first elastic support elements are evenly distributed along the circumference of the drive seat 19, which is beneficial to provide uniform and stable support for each corner of the drive seat 19 and improve the stability of the operation of the lens module 10.
[0049] For reference Figure 1 、 Figure 4 and Figure 8 In some embodiments, the aperture control element 13 is fixedly mounted on the drive base 19, and the first elastic support element of the support assembly further includes a fifth reed 165 and a sixth reed 166, wherein the fifth reed 165 is adjacent to the third reed 163, and the sixth reed 166 is adjacent to the fourth reed 164. One end of the third reed 163, the fourth reed 164, the fifth reed 165, and the sixth reed 166 are electrically connected to the focus control element 14 and the aperture control element 13, and the other ends are fixedly mounted on the base 18. Specifically, in one embodiment, the first reed 160 and the second reed 162 are electrically connected to two output pins of the focus control element 14 via two first traces 21, respectively. For example, the first reed 160 is electrically connected to the OUT1 pin of the focus control element 14, and the second reed 162 is electrically connected to the OUT2 pin of the focus control element 14. One end of the third reed 163 and the fourth reed 164 are both electrically connected to the focus control element 14 and the aperture control element 13. For example, the third reed 163 forms the VSS pin, and the fourth reed 164 forms the SDA pin. One end of the fifth reed 165 and the sixth reed 166 are both electrically connected to the focus control element 14 and the aperture control element 13. For example, the fifth reed 165 forms the VDD pin, and the sixth reed 166 forms the SCL pin.
[0050] Furthermore, in some embodiments, the other ends of the third reed 163, the fourth reed 164, the fifth reed 165, and the sixth reed 166 are all electrically connected to the anti-shake control element 15. Thus, the aperture control element 13, the focus control element 14, and the anti-shake control element 15 are connected in parallel via six reeds, so that an external power supply or control element can power and control the aperture control element 13, the focus control element 14, and the anti-shake control element 15 via four pins. This integrates the circuit connections of each control element and the support of the drive seat 19 into the six first elastic support elements, thereby improving the integration of components in the lens module 10 and reducing the number of components, thereby further simplifying the setup process of the lens module 10 and reducing the volume of the lens module 10.
[0051] In some embodiments, the first elastic support elements of the support assembly further include a seventh spring 167 and an eighth spring 168. The seventh spring 167 is adjacent to the first spring 160, the eighth spring 168 is adjacent to the second spring 162, the third spring 163 is adjacent to the fifth spring 165, and the fourth spring 164 is adjacent to the sixth spring 166. In other words, the eight first elastic support elements are adjacent to each other in pairs to form four groups, and the four groups of first elastic support elements are respectively connected to the four corners of the drive base 19. As a result, each corner of the drive base 19 has two first elastic support elements to provide a stable manufacturing function. On the basis of providing six first elastic support elements to achieve the circuit connection of the aperture control element 13, the focus control element 14, and the anti-shake control element 15, the number of first elastic support elements is further optimized so that the first elastic support elements can provide good support for the drive base 19, thereby further improving the operational stability of the lens module 10.
[0052] In some embodiments, the aperture control element 13, the focus control element 14 and the anti-shake control element 15 can all be IC chips, and the lens module 10 can also include an aperture driving magnet, which can adjust the aperture size of the variable aperture 12 under the control of the aperture control element 13.
[0053] Combine Figure 4 and Figure 9 As shown, in some embodiments, the lens module 10 further includes a second trace 22 and a circuit board 23. The second trace 22 is housed within the drive base 19. One end of the second trace 22 is electrically connected to the focus control element 14, while the other end is exposed on the outer surface of the drive base 19. One end of the circuit board 23 is electrically connected to the aperture control element 13, while the other end is fixedly mounted on the outer surface of the drive base 19. Furthermore, the third spring 163, the circuit board 23, and the second trace 22 are soldered to the outer surface of the drive base 19. It is understood that four second traces 22 may be provided, each electrically connected to the focus control element 14, and soldered to the third spring 163, the fourth spring 164, the fifth spring 165, and the sixth spring 166, respectively. The circuit board 23 not only provides electrical connection between the aperture control element 13 and the focus control element 14, but also securely connects the aperture control element 13, thereby securing the aperture control element 13 to the drive base 19. Figure 9 The enlarged partial view shown is the welding point of the third spring 163, the second trace 22 and the circuit board 23, as well as the welding point of the fourth spring 164, the second trace 22 and the circuit board 23. By welding the first elastic support element, the second trace 22 and the circuit board 23 to realize the parallel connection of the aperture control element 13 and the focus control element 14, the number of components and the setting process of the lens module 10 can be further simplified, thereby further reducing the volume of the lens module 10.
[0054] Combine Figure 1 、 Figure 4 and Figure 10 As shown, in some embodiments, the end of the first wire 21 is exposed on the outer surface of the driving seat 19 and welded to the first spring 160. Figure 10 As shown, in some embodiments, a welding window 161 is provided in the portion of the first reed 160 fixed on the drive seat 19 to provide positioning for the welding process, so that the first reed 160 and the first trace 21 are effectively welded at the welding window 161, thereby improving the stability of the setting process of the lens module 10.
[0055] refer to Figure 1 、 Figure 2 and Figure 4 As shown, in some embodiments, the support assembly of the lens module 10 further includes a plurality of second elastic support elements 24, which are spaced apart along the circumference of the lens structure 11. The two ends of the second elastic support elements 24 are respectively connected to the lens structure 11 and the drive seat 19, for example, connecting the lens barrel of the lens structure 11 and the drive seat 19, so that the lens structure 11 is suspended in the drive seat 19. The provision of the second elastic support elements 24 can provide a pre-load limit effect for the fixation of the lens structure 11 in the drive seat 19, making it difficult for the lens structure 11 to deflect or even fall out, thereby further improving the operational stability of the lens module 10.
[0056] It can be understood that in the present application, the setting of the first elastic support element and the second elastic support element 24 enables the drive seat 19 to be suspended on the base 18, and the lens structure 11 to be suspended in the drive seat 19. The base 18, the drive seat 19 and the lens structure 111 are mutually limited, so that in the process of the drive seat 19 driving the lens structure 111 to swing to realize the optical image stabilization function, the stability of the movement of the drive seat 19 and the lens structure 111 can be improved, thereby improving the operation stability of the lens module 10.
[0057] Furthermore, in some embodiments, the second elastic support element 24 is also electrically connected to the focus control element 14, so that the focus control element 14, the first reed 160, and the second elastic support element 24 can form a circuit. In some embodiments, the second elastic support element 24 and the focus control element 14 are electrically connected via a wire, and the wire between the second elastic support element 24 and the focus control element 14 also passes through the first magnet 171. For example, the wire is wrapped around the first magnet 171 to form a coil, and the coil at least partially bypasses the first magnet 171 to form an electromagnet with the first magnet 171, so that the focus control element 14 can adjust the magnetic field of the first magnet 171 through the coil, and then drive the driving member 19 to shake through the magnetic field to achieve the optical image stabilization function of the lens structure 11. The circuit setting between the focus control element 14, the second reed 162, and the second elastic support element 24 can be obtained by referring to the circuit setting of the focus control element 14, the first reed 160, and the second elastic support element 24.
[0058] It should be noted that in this embodiment, to enable the focus control element 14, the first reed 160, and the second elastic support element 24 to form a circuit, one second elastic support element 24 is connected to a corresponding first elastic support element, namely, the first reed 160. In other embodiments, when the first and second elastic support elements 24 only serve as structural support and do not connect circuits, or when the circuit configuration of the lens module 10 changes, one second elastic support element 24 may be connected to multiple first elastic support elements to further enhance the overall structural strength of the lens module 10.
[0059] In some embodiments, four second elastic support elements 24 are provided, and the four second elastic support elements 24 are respectively connected to the first spring 160, the second spring 162, the third spring 163, and the fourth spring 164. Specifically, the four second elastic support elements 24 can be integrally formed with the first spring 160, the second spring 162, the third spring 163, and the fourth spring 164. Thus, when the first elastic support element is fixedly mounted on the drive base 19, the corresponding second elastic support element 24 can also be fixedly mounted on the drive base 19. This allows the installation process of the second elastic support element 24 to be integrated with the installation process of the first elastic support element, further simplifying the installation process of the lens module 10 and facilitating the reduction of component mounting space, thereby further reducing the volume of the lens module 10. Furthermore, in some embodiments, the ends of the first elastic support element are connected to the ends of the corresponding second elastic support element 24, and the ends of the first elastic support element and the ends of the second elastic support element 24 are fixed to the drive base 19, thereby further enhancing the structural strength of the lens module 10.
[0060] In the present application, the focus control element 14 and the anti-shake control element 15 are electrically connected through the first elastic support element and the second elastic support element 24. It can be understood that the first elastic support element and the second elastic support element 24 electrically connect the first electronic element provided on the drive seat 19 and the second electronic element provided on the base 18. Therefore, while the first elastic support element and the second elastic support element 24 are provided to improve the operating stability of the lens module 10, the first elastic support element and the second elastic support element 24 can also play the role of line connection, which is beneficial to reduce the number of components in the lens module and simplify the setting process. Of course, in other embodiments, the first electronic element may not be the focus control element 14, and the second electronic element may not be the anti-shake control element 15. The first electronic element and the second electronic element may also be any other applicable electronic components in the lens module 10. In other words, the first elastic support element and the second elastic support element 24 can be used to electrically connect any two applicable electronic components provided at different positions in the lens module 10.
[0061] Please see again Figure 3 In some embodiments, the lens module 10 is further provided with a pre-load limiter 25. The pre-load limiter 25 is provided on the side of the lens structure 11 facing away from the iris diaphragm 12 to provide a pre-load limiter for the lens structure 11 on the side facing away from the iris diaphragm 12, thereby further improving the operational stability of the lens structure 11 in the lens module 10. In some embodiments, the pre-load limiter 25 includes a fixed portion 251, an elastic portion 252, and a connecting portion 253. The fixed portion 251 is fixedly provided on the side of the lens structure 11 facing away from the iris diaphragm 12. The connecting portion 253 is fixedly provided on the drive base 19, for example, fixedly connected to the side of the drive base 19 facing away from the iris diaphragm 12. The two ends of the elastic portion 252 are respectively connected to the fixed portion 251 and the connecting portion 253. Specifically, four elastic parts 252 and four connecting parts 253 can be provided, and the four elastic parts 252 and the four connecting parts 253 are connected one by one, and the four elastic parts 252 are evenly arranged along the circumference of the lens structure 11, thereby providing a stable and reliable pre-compression limiting effect for the lens structure 11 at the four corners of the lens structure 11, further improving the stability of the operation of the lens module 10.
[0062] refer to Figure 3 、 Figure 5 and Figure 6As shown, in some embodiments, the lens module 10 further includes an anti-shake circuit board 26 disposed on the base 18. For example, the anti-shake circuit board 26 is fixedly disposed on a side of the base 18 facing the lens structure 11. The anti-shake control element 15 is disposed on the base 18. The first reed 160, the second reed 162, the third reed 163, the fourth reed 164, the fifth reed 165, and the sixth reed 166 are fixedly connected to the anti-shake circuit board 26 and can establish an electrical connection with the anti-shake control element 15 through the anti-shake circuit board 26.
[0063] Specifically, in some embodiments, the base 18 is provided with a receiving groove 181. The anti-shake control element 15 is connected to the side of the anti-shake circuit board 26 facing away from the lens structure 11 and is received in the receiving groove 181. Thus, the base 18 can provide a receiving space for the anti-shake control element 15, thereby reducing the space occupied by the anti-shake control element 15 in the axial direction and further reducing the volume of the lens module 10. It is understood that two anti-shake control elements 15 can be provided, with the two anti-shake control elements 15 correspondingly received in the two receiving grooves 181 of the base 18. The two anti-shake control elements 15 correspond to the positions of the first magnet 170 and the second magnet 175, respectively, thereby controlling the movement of the lens structure 11 in the first direction and the second direction, respectively.
[0064] In some embodiments, the base 18 further comprises a welding groove 182. The ends of each first elastic support element of the first spring 160 through the eighth spring 168 are welded to the anti-shake circuit board 26. The welds between each first elastic support element and the anti-shake circuit board 26 are located within the welding groove 182. In other words, the welding points, such as solder joints, between each first elastic support element and the anti-shake circuit board 26 are accommodated within the welding groove 182. Thus, the welding groove 182 provides space for the welding between each first elastic support element and the anti-shake circuit board 26, thereby further reducing the axial dimensions and volume of the lens module 10. It is understood that the four corners of the base 18 may each be provided with a welding groove 182. Four sets of first elastic support elements are correspondingly welded to the anti-shake circuit board 26 within the welding groove 182. For example, the first spring 160 and the seventh spring 167 are welded to the anti-shake circuit board 26 within the same welding groove 182, with the welds between the first spring 160 and the seventh spring 167 spaced apart. It should be noted that the welding point between the first reed 160 and the anti-shake circuit board 26 also establishes an electrical connection between the first reed 160 and the anti-shake circuit board 26, so that the first reed 160 can be electrically connected to the anti-shake control element 15 through the anti-shake circuit board 26, and the welding between the seventh reed 167 and the anti-shake circuit board 26 can only be used to fix the seventh reed 167 on the base 18. The first reed 160 does not need to establish an electrical connection with the anti-shake circuit board 26. The same applies to other first elastic support elements.
[0065] In some embodiments, the base 18 further defines a pin slot 183. The anti-shake circuit board 26 defines a connecting pin 261 protruding in a direction facing away from the drive base 19. The connecting pin 261 is at least partially accommodated within the pin slot 183. It is understood that the first reed 160, the second reed 162, the third reed 163, the fourth reed 164, the fifth reed 165, the sixth reed 166, and the anti-shake circuit board 26 collectively connect the aperture control element 13, the focus control element 14, and the anti-shake control element 15 in parallel, forming four pins on the connecting pin 261 for connection to external power supply or control elements. By connecting an external power supply or control element to the four pins of the connecting pins 261, electrical connections can be established with the aperture control element 13, the focus control element 14, and the anti-shake control element 15. In other words, the coordinated design of the first elastic support element and the anti-shake circuit board 26 can greatly improve the circuit integration of the lens module 10, reduce the number of components in the lens module 10, and thus effectively reduce the size of the lens module 10. In addition, the base 18 is provided with a pin slot 183 to accommodate the connecting pin 261, which can also reduce the space occupied by the connecting pin 261 in the axial direction, thereby further compressing the axial size of the lens module 10.
[0066] In some embodiments, the lens module 10 also includes a flexible circuit board 27, which is arranged on the side of the base 18 away from the driving seat 19 and is electrically connected to the connecting pin 261. One end of the flexible circuit board 27 extends to the outside of the base 18 for electrical connection to an external power supply or control element, thereby establishing an electrical connection between the external element and the connecting pin 261.
[0067] The present application also provides an electronic device, comprising a fixing member and a lens module 10 as described in any of the above embodiments, wherein the lens module 10 is disposed within the fixing member. Specifically, the electronic device may be a device with an integrated imaging function, such as a camera, a smartphone, a tablet computer, or an e-reader. The fixing member may be a component in the electronic device for fixing, carrying, or installing the lens module 10. When the above-mentioned lens module 10 is used in the electronic device, the lens module 10 is small in size, has a high degree of component integration, and has good structural stability, which is conducive to compressing the size of the electronic device and improving the operational stability of the electronic device.
