Of course, the described embodiments are only a part, not all, of the embodiments of the present invention. All other embodiments that can be obtained by those skilled in the art based on the embodiments of the present invention without creative efforts fall within the scope of protection of the present invention.

[0026] As shown in FIGS. 1 to 8 , an embodiment of the present invention provides a lens module 10 including a frame mechanism 100 and an adjustment mechanism 200, in which the frame mechanism 100 includes a base structure 110, a support frame 120, and a lens barrel 130, the support frame 120 is suspended within the base structure 110, and a movable cavity 1211 is provided within the support frame 120, and the lens barrel 130 is suspended within the movable cavity 1211, the adjustment mechanism 200 includes a magnet steel component 210, an image stabilization component 220, and a focus component 230, the magnet steel component 210 is connected to the support frame 120 and at least partially surrounds the movable cavity 1211, and the image stabilization component 220 includes an image stabilization coil 221 and an image stabilization reset member 222. the image stabilization reset member 222 is connected to the lens barrel 130 and the support frame 120 respectively, the image stabilization coil 221 is connected to the lens barrel 130 and is used to drive the lens barrel 130 to move relative to the support frame 120; the focus component 230 comprises a focus coil 231 and a focus reset member 232, the focus reset member 232 is connected to the support frame 120 and the base structure 110 respectively, the focus coil 231 is connected to the base structure 110 and is used to drive the support frame 120 to move relative to the base structure 110, wherein the image stabilization coil 221 and the focus coil 231 are respectively provided on opposite sides of the magnet steel component 210, and the focus coil 231 is located inside the movable cavity 1211.

[0027] In the lens module 10 of this embodiment, the magnetic steel component 210 is installed in both the image stabilization component 220 and the focus component 230 to cooperate with each other simultaneously, so that the image stabilization coil 221 and the focus coil 231 share one set of the magnetic steel component 210 to realize the optical image stabilization and autofocus functions of the lens module 10, allowing the lens module 10 to have a more compact structure. Furthermore, compared to the conventional lens module 10, the number of parts is reduced, reducing the mass of the moving parts and effectively improving the accuracy and stability of the image stabilization and focusing of the lens module 10, thereby improving the performance of the lens module 10.

[0028] Specifically, as shown in FIG. 3, a receiving cavity 1111 is provided in the frame mechanism 100, the support frame 120 is suspended in the receiving cavity 1111 of the base structure 110, and the interior of the lens barrel 130 is used to mount the lens of the lens module 10. L in FIG. 1 is defined as the optical axis L of the lens barrel 130, and this optical axis L usually overlaps with the optical axis of the lens in the lens barrel 130.

[0029] In this embodiment, the image stabilization reset member 222 is electrically connected to the image stabilization coil 221 and the support frame 120, respectively, and the focus reset member 232 is electrically connected to the focus coil 231 and the support frame 120, respectively.

[0030] As a result, the image stabilization component 220 and the focus component 230 are both electrically connected and are connected to external elements via the focus circuit board 235 of the focus component 230, thereby achieving signal transmission and power supply functions. Furthermore, because the image stabilization component 220 and the focus component 230 are electrically connected to external elements via the same circuit, the overall structure of the adjustment mechanism 200 can be made more compact. Therefore, the overall structure of the lens module 10 also becomes more compact, making it easier to install in electronic devices.

[0031] In some embodiments, the image stabilization component 220 includes two sets of image stabilization coils 221, which are used to control the lens barrel 130 to move along the X and Y directions perpendicular to the optical axis L to achieve the OIS image stabilization effect, and the focus coil 231 cooperates with the magnetic steel component 210 to drive the support frame 120 to move along a direction parallel to the optical axis L. In this case, the two image stabilization coils 221 and the focus coil 231 are connected in parallel to each other and are electrically connected to an external circuit via four circuit contacts 2351 on the focus circuit board 235, thereby simultaneously achieving the OIS image stabilization and AF focus functions and making the circuit structure more compact.

[0032] 3 to 7 , in one embodiment, the base structure 110 includes a base body 111 and a base insert 112, and the support frame 120 includes a frame body 121 and a frame insert 122. The base insert 112 fitted in the base body 111 is connected to the image stabilization reset member 222, and the frame insert 122 fitted in the frame body 121 is connected to the image stabilization reset member 222 and the focus reset member 232, respectively. This achieves circuit conduction between the image stabilization component 220 and the focus component 230, while also improving the overall strength of the base structure 110 and the support frame 120 and making the structures of the base structure 110 and the support frame 120 more compact. In other embodiments, the base structure 110 and the support frame 120 may achieve electrical connection using external wiring, LDS (Laser Direct Structuring) technology, or other methods, which are not limited herein.

[0033] Specifically, as shown in Figures 5 and 6, the image stabilization reset member 222 comprises a flexible structure 2221 and a suspension wire 2222, the flexible structure 2221 is connected to the lens barrel 130, the opposing ends of the suspension wire 2222 are connected to the flexible structure 2221 and the support frame 120, respectively, and the suspension wire 2222 is arranged outside the lens barrel 130 and parallel to the optical axis L of the lens barrel 130.

[0034] By connecting flexible structure 2221 and suspension wire 2222 to form image stabilization reset member 222, when lens barrel 130 moves relative to support frame 120 due to the driving of image stabilization coil 221, flexible structure 2221 deforms and resets lens barrel 130. By connecting suspension wire 2222 to support frame 120, the structures of image stabilization reset member 222 and support frame 120 can be made more compact, and the overall structure of lens module 10 can be made more compact.

[0035] In this embodiment, the image stabilization component 220 further includes an image stabilization circuit board 223, which is preferably an FPC, so that the image stabilization circuit board 223 can be thinner. The image stabilization circuit board 223 is electrically connected to each of the multiple image stabilization reset members 222, thereby realizing an electrical connection function and simultaneously fixing the multiple image stabilization reset members 222.

[0036] 6 , in one embodiment, the flexible structure 2221 includes a first fixing portion 22211, a first connecting portion 22212, and at least one first flexible arm 22213, and the first flexible arm 22213 is connected to the first fixing portion 22211 and the first connecting portion 22212, respectively. The first fixing portion 22211 is connected to the lens barrel 130, and the first connecting portion 22212 is suspended outside the first flexible arm 22213 and connected to the suspension wire 2222. When there are multiple first flexible arms 22213, the multiple first flexible arms 22213 are arranged symmetrically from the suspension wire 2222, and the multiple first flexible arms 22213 are connected to the first fixing portion 22211 and the first connecting portion 22212, respectively.

[0037] In this embodiment, the end of the suspension wire 2222 is welded to the first connecting portion 22212, and a certain amount of solder is preferably applied to the connection portion between the suspension wire 2222 and the first connecting portion 22212 to enhance the fastening strength between the two. When the lens barrel 130 moves relative to the support frame 120, the first flexible arm 22213 can deform and store elastic potential energy. After the driving force of the image stabilization coil 221 is removed / or when the elastic force of the first flexible arm 22213 overcomes the force caused by the vibration of the electronic device, the first flexible arm 22213 can reset the lens barrel 130 and achieve the image stabilization function. Connecting multiple first flexible arms 22213 to the first fixing portion 22211 and the first connecting portion 22212, respectively, can improve the elastic force of the first flexible arm 22213 and enhance the reset effect of the flexible structure 2221. 6, in a preferred embodiment, the extension path of the first flexible arm 22213 preferably has a curved surround structure in order to increase the deformation range and reset effect of the first flexible arm 22213. Specifically, the number of image stabilization reset members 222 may be two, three, four, or more than four, and multiple image stabilization reset members 222 may be uniformly arranged along the circumference of the lens barrel 130, and multiple image stabilization reset members 222 may be arranged to connect to the lens barrel 130, thereby improving the image stabilization effect and reset stability of the image stabilization component 220.

[0038] In one embodiment, an escape hole 132 is opened in the outer wall of the lens barrel 130, and the escape hole 132 is provided to surround the suspension wire 2222.

[0039] Furthermore, by arranging the escape hole 132 to cooperate with the suspension wire 2222, it is possible to prevent the lens barrel 130 from colliding with the suspension wire 2222 during deformation, thereby increasing the durability of the suspension wire 2222, and also to make the combined structure of the suspension wire 2222 and the support frame 120 more compact, which contributes to realizing the design needs for a more compact lens module 10.

[0040] Furthermore, as shown in Figures 5, 6 and 8, a first escape groove 131 is opened in the lens barrel 130, and the first escape groove 131 is provided on the side of the lens barrel 130 facing the flexible structure 2221, and the orthogonal projection of the flexible structure 2221 on the lens barrel 130 at least partially overlaps with the first escape groove 131.

[0041] In this embodiment, the first escape groove 131 and the flexible structure 2221 are arranged to cooperate with each other on the lens barrel 130, so that when the lens barrel 130 moves relative to the support frame 120 and deformation occurs, the first escape groove 131 retracts the first flexible arm 22213, thereby avoiding a collision between the lens barrel 130 and the image stabilization reset member 222, thereby increasing the durability of the image stabilization reset member 222 and making the structure between the image stabilization reset member 222 and the support frame 120 more compact.

[0042] As shown in Figures 5 and 7, in one embodiment, the support frame 120 further includes a cover plate 123, which is detachably connected to the frame body 121 and is arranged to cover the upper side of the image stabilization reset member 222.

[0043] When assembling the lens module 10 of this embodiment, first, the image stabilization reset member 222 is connected to the frame body 121 and the lens barrel 130, respectively, and then the cover plate 123 is placed on the top of the frame body 121 to seal the opening of the movable cavity 1211, and a light passage hole corresponding to the lens barrel 130 is formed in the cover plate 123. As a result, after the cover plate 123 and the frame body 121 are connected, the cover plate 123 and the lens barrel 130 are spaced apart, and the cover plate 123 blocks dust, impurities, etc. from the external environment and protects the lens barrel 130 and the image stabilization component 220 inside the movable cavity 1211, thereby improving the durability of the lens module 10.

[0044] Specifically, as shown in Figures 3, 7 and 8, the focus reset member 232 is provided on the side of the support frame 120 away from the image stabilization reset member 222, and the focus reset member 232 has a second fixed portion 2321, a second flexible arm 2323 and a second connecting portion 2322, and the second flexible arm 2323 is connected to the second fixed portion 2321 and the second connecting portion 2322, respectively, the second fixed portion 2321 is connected to the base structure 110, and the second connecting portion 2322 is connected to the support frame 120.

[0045] In this embodiment, the focus reset member 232 is installed to connect to the support frame 120 and the base structure 110, respectively. When the support frame 120 moves relative to the base structure 110, the focus reset member 232 provides the support frame 120 with an elastic force for resetting the support frame 120. The focus reset member 232 also provides an electrical connection between the base structure 110 and the support frame 120. When the focus reset member 232 deforms, the second flexible arm 2323 deforms and stores elastic potential energy, ultimately driving the second fixing portion 2321 to move in a resetting movement relative to the second connecting portion 2322, resetting the support frame 120. The second fixing portion 2321 is electrically connected to the base insert 112 of the base structure 110, and the second connecting portion 2322 is electrically connected to the frame insert 122 of the support frame 120.

[0046] Furthermore, as shown in FIG. 7, a second escape groove 133 is provided in the lens barrel 130, and the second escape groove 133 is provided on the side of the lens barrel 130 facing the focus reset member 232, and at least a portion of the orthogonal projection of the focus reset member 232 on the lens barrel 130 overlaps with the second escape groove 133.

[0047] As a result, when lens barrel 130 moves relative to base structure 110 and is deformed, second relief groove 133 allows second flexible arm 2323 to retract to prevent a collision between lens barrel 130 and focus reset member 232, thereby increasing the durability of focus reset member 232 and making the structure between focus reset member 232 and lens barrel 130 more compact. Specifically, the number of focus reset members 232 may be two, three, four, or more than four, and multiple focus reset members 232 may be uniformly arranged along the circumferential direction of support frame 120 and connected to support frame 120, thereby improving the image stabilization effect and reset stability of focus component 230.

[0048] Specifically, as shown in Figures 4 and 5, the focus component 230 further includes at least one set of guide structures 233, which are movably connected to the base structure 110 and the support frame 120, respectively, and are used to drive the support frame 120 to move along a direction parallel to the optical axis L of the lens barrel 130.

[0049] In this embodiment, the guide structure 233 is installed to cooperate with the base structure 110 and the support frame 120 respectively. When the focus component 230 drives the movement of the support frame 120 to perform focus adjustment, the guide structure 233 limits the movement of the support frame 120 relative to the base structure 110, ensuring that the support frame 120 moves in a direction parallel to the optical axis L of the telescope tube 130, thereby preventing the support frame 120 from shifting relative to the base structure 110 and improving the focus accuracy of the focus component 230.

[0050] Specifically, as shown in Figures 4, 6 and 7, a first guide groove 1112 is opened in the base structure 110, a second guide groove 1212 is opened in the support frame 120, the guide structure 233 includes a guide member 2331 and a stopper portion 2332, the guide member 2331 is movably arranged between the first guide groove 1112 and the second guide groove 1212, and the stopper portion 2332 is arranged at the opening of the first guide groove 1112 or the second guide groove 1212 along the movement path of the guide member 2331.

[0051] In this embodiment, the extending direction of the first guide groove 1112 and the second guide groove 1212 is parallel to the optical axis L. As a result, the first guide groove 1112 and the second guide groove 1212 cooperate with the guide member 2331 to guide the movement of the guide member 2331 and realize the function of limiting the movement of the support frame 120. At the same time, a stopper portion 2332 is provided at the opening of the first guide groove 1112 or the second guide groove 1212 to limit the movement of the guide member 2331, thereby preventing the guide member 2331 from escaping from the first guide groove 1112 or the second guide groove 1212. The stopper portion 2332 may be connected to the base main body 111 or the frame main body 121, and is not limited here.

[0052] In one embodiment, the guide member 2331 includes a ball, which rolls in the first guide groove 1112 and the second guide groove 1212, respectively.

[0053] As a result, when the support frame 120 moves relative to the base structure 110, the balls slide relative to the first guide groove 1112 and the second guide groove 1212, ensuring that the support frame 120 moves relative to the base structure 110 in a direction parallel to the optical axis L. In a preferred embodiment, there are multiple balls, and the multiple balls are sequentially arranged in a direction parallel to the optical axis L and housed between the first guide groove 1112 and the second guide groove 1212. Specifically, the first guide groove 1112 and the second guide groove 1212 may be a V-shaped groove, an arcuate groove, or the like, but this is not limited thereto.

[0054] In another embodiment, the guide member 2331 may be a roller, with the central axis of the ball perpendicular to the optical axis L and parallel to the bottom surface of the base structure 110. In this case, the first guide groove 1112 and the second guide groove 1212 must limit the axial movement of the guide member 2331. In a preferred embodiment, the number of guide structures 233 may be multiple sets, and the multiple sets of guide structures 233 are respectively connected to the base structure 110 and the support frame 120, thereby improving the guiding stability and accuracy of the guide structures 233.

[0055] Specifically, as shown in FIG. 3 , the focus component 230 further includes a yoke 234, which is connected to the base structure 110 and magnetically attracted to the magnetic steel component 210 to drive the support frame 120 and the base structure 110 to abut on opposite sides of the guide structure 233.

[0056] In this embodiment, by installing the yoke 234 to cooperate with the magnetic steel component 210, the yoke 234 can be magnetically attracted to the magnetic steel component 210 so as to abut the support frame 120 against the guide structure 233 and press the guide structure 233 against the base structure 110. This can limit the movement of the support frame 120 relative to the base structure 110 along a direction perpendicular to the optical axis L.

[0057] As shown in Figures 6 and 8, in one embodiment, the support frame 120 has two mounting grooves 1213, the magnetic steel component 210 has a plurality of magnetic steel pieces, with at least one magnetic steel piece provided in each mounting groove 1213, the image stabilization coil 221 magnetically cooperates with the magnetic steel pieces to drive the lens barrel 130 to move relative to the support frame 120 in a direction perpendicular to the optical axis L of the lens barrel 130, and the focus coil 231 magnetically cooperates with the magnetic steel pieces to drive the support frame 120 to move relative to the base structure 110 in a direction parallel to the optical axis L.

[0058] In this embodiment, the magnetic steel component 210 includes a first magnetic steel 211 and a second magnetic steel 212, and two image stabilization coils 221. The two image stabilization coils 221 correspond to the first magnetic steel 211 and the second magnetic steel 212, respectively. This provides driving forces in the X and Y directions to the lens barrel 130 in directions perpendicular to the optical axis L, thereby realizing the OIS image stabilization driving function of the image stabilization component 220. In the embodiment shown in FIGS. 6 and 8 , the cross section of the frame body 121 is rectangular, and two mounting grooves 1213 are provided on two adjacent sides of the frame body 121. The first magnetic steel 211 and the second magnetic steel 212 are each provided in one of the mounting grooves 1213. In other embodiments, the number of magnetic steels in the magnetic steel component 210 may be three, four, or more than four. This number can be determined based on the image stabilization driving needs of the image stabilization component 220.

[0059] 5 and 8, the focusing component 230 further includes a focusing circuit board 235, and the focusing coil 231 is connected to the focusing circuit board 235. The base structure 110 has a communicating accommodating groove 1113 and an accommodating hole 1114, and the accommodating groove 1113 is located on the outer wall of the base structure 110. The focusing circuit board 235 is connected to the base structure 110 and is accommodated in the accommodating groove 1113, and the focusing coil 231 is accommodated in the accommodating hole 1114.

[0060] As a result, when assembling the lens module 10, the focus circuit board 235 is mounted in the accommodating groove 1113 and the focus coil 231 is positioned in the accommodating hole 1114, thereby forming a more compact combined structure between the focus circuit board 235 and the base structure 110.

[0061] In one embodiment, the focus circuit board 235 has four circuit contacts 2351, and the four circuit contacts 2351 are electrically connected to the four sets of image stabilization reset members 222 and focus reset members 232 via the four base inserts 112, respectively. In this embodiment, the ICs of the two image stabilization coils 221 of the focus component 230 and the image stabilization component 220 are connected in parallel, respectively, and connected to the four circuit contacts 2351 of the focus circuit board 235, where two circuit contacts 2351 are used for power supply (VCC) and ground (GND) of the focus circuit board 235, and the other two circuit contacts 2351 are used to transmit control signals (including, but not limited to, analog signals and digital signals) to the two image stabilization coils 221 and the focus coil 231, respectively. In this case, the focus circuit board 235 can be electrically connected to an external control circuit through the four circuit contacts 2351. The overall structure is compact, which simplifies the arrangement of the lens module 10 in an electronic device.

[0062] Specifically, the lens module 10 further includes a housing 300, which is detachably connected to the frame mechanism 100 and is arranged to cover the accommodating cavity 1111, and the housing 300 has a hole corresponding to the lens barrel 130, thereby realizing a light transmission function.

[0063] As can be appreciated, by cooperating with the base structure 110 to install the housing 300, the housing 300 can protect the adjustment mechanism 200 inside the base structure 110 and block out dust, impurities, etc. from the outside.

[0065] In the electronic device of this embodiment, the lens module 10 of any one of the above embodiments is installed, and the magnetic steel component 210 in the lens module 10 is installed so that the image stabilization component 220 and the focus component 230 work together at the same time. The image stabilization coil 221 and the focus coil 231 share one set of the magnetic steel component 210, thereby realizing the optical image stabilization and autofocus functions of the lens module 10. This allows the lens module 10 to have a more compact structure, making it easier to install in the host electronic device and meeting the demand for miniaturized design of electronic devices. Specifically, the electronic device may include, but is not limited to, a tablet or smartphone.
