[0018] In order to make the objectives, technical ideas and advantages of the present invention clearer, the technical ideas of the present invention will be clearly and completely described below in conjunction with the drawings of the present invention. 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.

[0019] 1 to 8, an embodiment of the present invention provides a lens module 10 including a mounting structure 100, a support frame 200, a lens barrel 300, and an adjustment mechanism 400. The mounting structure 100 includes an upper shell 110 and a base 120. The upper shell 110 includes a top cover 111 and a side wall 112. The side wall 112 is connected to the base 120. The top cover 111 is located on the side of the side wall 112 away from the base 120. The base 120 is used for electrical connection to an external circuit. The support frame 200 is suspended within the mounting structure 100. The lens barrel 300 is suspended within the support frame 200. The adjustment mechanism 400 includes a focus component 410, an image stabilization component 420, a plurality of elastic sheet structures 430, and suspension wires 440. The focus component 410 is a focus coil. The lens barrel 300 includes a coil 411, a focus magnet 412, and a focus circuit board 413, wherein the focus coil 411 is wound around and installed on the lens barrel 300, the focus magnet 412 is connected to the side of the top cover part 111 facing the focus coil 411, the image stabilization component 420 is connected to the base 120 and the support frame 200 respectively, and is used to drive the support frame 200 to move relative to the base 120, the elastic sheet structure 430 is connected to the support frame 200 and the lens barrel 300 respectively, the suspension wire 440 is connected and electrically connected to the support frame 200 and the base 200 respectively, and the focus circuit board 413 is installed on the lens barrel 300, and the elastic sheet structure 430 is electrically connected to the focus circuit board 413, the image stabilization component, and the support frame 200 respectively.

[0020] In the lens module 10 of this embodiment, the focus magnet 412 is located inside the top cover part 111 of the upper shell 110, thereby making full use of the internal space of the upper shell 110 and making the structure between the lens barrel 300, the focus component 410, and the upper shell 110 more compact, thereby making the overall structure of the lens module 10 more compact and easier to install in electronic devices. Furthermore, the elastic sheet structure 430 is electrically connected to the focus component 410 and the image stabilization component 420, thereby realizing the power supply and signal transmission functions of the lens module 10 and further achieving the goal of optimizing the internal structure of the lens module 10.

[0021] In addition, by installing the focus magnet 412 in the upper shell 110 (corresponding to the fixed member) of the mounting structure 100, the overall mass of the moving part can be effectively reduced compared to the conventional lens module 10 in which the magnet is installed in the moving part, the magnitude of the driving force required when the focus component 410 is moving can be reduced, and the movement accuracy can be improved. This avoids the problem of the focus magnet 412 generating an attractive or repulsive force on other parts within the lens module 10 when the focus component 410 and the image stabilization component are moving, and improves the control accuracy of the lens module 10.

[0022] 1, 3, and 8, in one embodiment, support frame 200, focus coil 411, and focus magnet 412 are arranged in a direction parallel to the optical axis of lens barrel 300, and base insert 122 is embedded inside base 120. Support frame 200 includes frame body 210 and frame insert 220. Base insert 122 embedded in base 120 is connected to elastic sheet structure 430, and frame insert 220 embedded in frame body 210 is connected to image stabilization component 420 and elastic sheet structure 430, respectively, thereby realizing circuit conduction between image stabilization component 420 and focus component 410. Furthermore, the strength of the entire base 120 and support frame 200 can be improved, and the overall structure of base 120 and support frame 200 can be made more compact. In other embodiments, the base 120 and the support frame 200 can also employ external circuits, LDS technology (Laser Direct Structuring), etc. to achieve electrical connection functions, but this is not uniquely limited herein.

[0023] 4, the focus circuit board 413 is arranged to surround the opening of the lens barrel 300 and is connected to a plurality of sets of elastic sheet structures 430, and the focus circuit board 413 is electrically connected to the elastic sheet structures 430. In this embodiment, the image stabilization circuit board 423 is preferably an FPC, which makes the image stabilization circuit board 423 thinner and electrically connects the image stabilization circuit board 423 to the elastic sheet structures 430, thereby achieving an electrical connection function. As shown in FIG. 7, the image stabilization circuit board 423 is attached to the bottom of the support frame 200 and arranged to surround the lens barrel.

[0024] 2 to 6 and 8, elastic sheet structure 430 includes an upper elastic sheet 431, and upper elastic sheet 431 and image stabilization coil 421 are respectively installed on opposite sides in the axial direction of support frame 200, and more specifically, can be respectively installed on opposite sides of support frame 200 along the optical axis of lens barrel 300, and upper elastic sheet 431 is connected to support frame 200 and lens barrel 300, and lower elastic sheet 432 is connected to support frame 200 and lens barrel 300, and support frame 200 is electrically connected to focus coil 411 and image stabilization component 420, respectively, and suspension wire 440 is respectively connected and electrically connected to upper elastic sheet 431 and base 120.

[0025] With this arrangement, when lens barrel 300 moves relative to support frame 200 due to the driving action of image stabilization coil 421, upper elastic sheet 431 deforms, driving lens barrel 300 to return to its original position. By connecting suspension wires 440 to support frame 200, support frame 200 can be driven to return to base 120, which makes it possible to make the structure of upper elastic sheet 431 and support frame 200 more compact, and thus the structure of the entire lens module 10 more compact.

[0026] Specifically, referring to FIG. 5, the upper elastic sheet 431 includes at least one first flexible arm 4311 and at least two first connection portions 4312, wherein the two first connection portions 4312 are respectively connected to the lens barrel 300 and the support frame 200, the first flexible arm 4311 is respectively connected to the multiple first connection portions 4312, and the opposing ends of the suspension wire 440 are respectively connected and electrically connected to the first connection portion 4312 and the base 120.

[0027] In this embodiment, the end of the suspension wire 440 can be fixed to the first connecting portion 4312 by welding. To improve the fixing strength, it is preferable to cover the connection portion between the suspension wire 440 and the first connecting portion 4312 with a certain amount of solder. When the lens barrel 300 moves relative to the support frame 200, the first flexible arm 4311 can deform and store elastic potential energy. After the driving force of the image stabilization component 420 is removed and / or when the elastic force of the first flexible arm 4311 overcomes the force generated by the vibration of the electronic device, the first flexible arm 4311 can drive the lens barrel 300 to return to its original position. Using multiple first flexible arms 4311 connected to two first connecting portions 4312, respectively, improves the elastic force of the first flexible arms 4311, thereby improving the return effect of the upper elastic sheet 431. 5, in a preferred embodiment, the extension path of the first flexible arm 4311 preferably has a curved surround structure in order to improve the deformation range and recovery effect of the first flexible arm 4311. Specifically, the number of upper elastic sheets 431 may be two, three, four, or more than four, and the multiple upper elastic sheets 431 may be evenly arranged along the circumferential direction of the lens barrel 300. By providing multiple upper elastic sheets 431 connected to the lens barrel 300, the vibration isolation effect and reset stability of the image stabilization component 420 can be improved.

[0028] In some embodiments, the upper elastic sheet 431 is integrally formed with the suspension wires 440 .

[0029] By installing them in this manner, the strength of the entire elastic structure formed by combining the upper elastic sheet 431 and the suspension wire 440 can be increased, and at the same time, the combination of the two results in a more compact structure, making the lens module 10 smaller.

[0030] Furthermore, the lens barrel 300 is provided with a first clearance groove 310, which is provided on the side of the lens barrel 300 facing the first flexible arm 4311, and the orthogonal projection of the first flexible arm 4311 on the lens barrel 300 at least partially overlaps with the first clearance groove 310.

[0031] In this embodiment, the lens barrel 300 is provided with a first escape groove 310 which cooperates with the upper elastic sheet 431, so that when the lens barrel 300 moves and deforms relative to the support frame 200, the first escape groove 310 can avoid the first flexible arm 4311, thereby preventing collision between the lens barrel 300 and the upper elastic sheet 431, improving the durability of the upper elastic sheet 431, and making the structure between the upper elastic sheet 431 and the support frame 200 and lens barrel 300 more compact.

[0032] In one embodiment, the support frame 200 is provided with a second undercut groove 212, which is provided on the side of the support frame 200 facing the first flexible arm 4311, and the orthogonal projection of the first flexible arm 4311 on the support frame 200 at least partially overlaps with the second undercut groove 212.

[0033] In this embodiment, by providing a second escape groove 212 in the support frame 200 and cooperating with the upper elastic sheet 431, when the lens barrel 300 moves relative to the support frame 200, the second escape groove 212 can avoid the first flexible arm 4311, preventing collision between the support frame 200 and the upper elastic sheet 431. This improves the durability of the upper elastic sheet 431 and makes the structure between the upper elastic sheet 431 and the support frame 200 more compact.

[0034] Furthermore, as shown in Figures 5 and 6, the upper elastic sheet 431 includes a second flexible arm 441 and a second connection portion 4314, and the second flexible arm 441 is respectively connected to the second connection portion 4314 and one first connection portion 4312, and one end of the suspension wire 440 far from the base 120 is connected to the second connection portion 4314.

[0035] In this embodiment, the end of the suspension wire 440 and the second connecting portion 4314 are welded together. To improve the strength of the connection between the suspension wire 440 and the second connecting portion 4314, it is preferable to cover the connecting portion between the suspension wire 440 and the second connecting portion 4314 with a certain amount of solder. When the support frame 200 moves relative to the base 120, the second flexible arm 441 deforms and stores elastic potential energy. When the driving force of the image stabilization component 420 is removed / or when the elastic force of the second flexible arm 441 overcomes the force generated by the vibration of the electronic device, the second flexible arm 441 can drive the support frame 200 to return to its original position, thereby achieving the vibration-damping function. Using multiple second flexible arms 441 to connect to the first connecting portion 4312 and the second connecting portion 4314, respectively, can increase the elastic force of the second flexible arm 441, thereby improving the return effect of the upper elastic sheet 431. In a preferred embodiment, in order to improve the deformation range and recovery effect of the second flexible arm 441, the extension path of the second flexible arm 441 is preferably a curved surround structure.

[0036] Referring to Figure 6, in one embodiment, the support frame 200 is provided with a third undercut groove 213, which is provided on the side of the support frame 200 facing the second flexible arm 441, and the orthogonal projection of the second flexible arm 441 on the support frame 200 at least partially overlaps with the third undercut groove 213.

[0037] In this embodiment, by providing a third escape groove 213 in the support frame 200 and cooperating with the upper elastic sheet 431, when the lens barrel 300 moves relative to the support frame 200, the third escape groove 213 can avoid the first flexible arm 4311, thereby preventing collision between the support frame 200 and the upper elastic sheet 431, improving the durability of the upper elastic sheet 431, and making the structure between the upper elastic sheet 431 and the support frame 200 more compact.

[0038] Further, referring to Figures 3, 5, 7, and 8, the elastic sheet structure 430 further includes a lower elastic sheet 432, which is connected to the lens barrel 300 and the support frame 200, respectively, and the lower elastic sheet 432 is provided on the side of the support frame 200 away from the upper elastic sheet 431.

[0039] With this configuration, when the lens barrel 300 moves relative to the support frame 200, the two are connected via the installed lower elastic sheet 432, which can apply an elastic driving force to the lens barrel 300 for resetting, and can also cushion the vibration of the lens barrel 300 relative to the support frame 200.

[0040] Specifically, as shown in FIG. 7 , the lower elastic sheet 432 includes a flexible connecting arm 4321 and at least two reset fixing portions 4322, which are respectively connected to the flexible connecting arm 4321, where the two reset fixing portions 4322 are respectively connected to the lens barrel 300 and the support frame 200.

[0041] In this embodiment, when the lens barrel 300 moves relative to the support frame 200, the flexible connecting arm 4321 can deform and store elastic potential energy. When the driving force of the focus component 410 is removed and / or the elastic force of the flexible connecting arm 4321 overcomes the force generated by the vibration of the electronic device, the flexible connecting arm 4321 can drive the lens barrel 300 to return to its original position. Using multiple flexible connecting arms 4321, each connected to a reset fixture 4322, can increase the elastic force of the flexible connecting arm 4321, thereby improving the return effect of the upper elastic sheet 431. As shown in FIG. 7 , in a preferred embodiment, the extension path of the flexible connecting arm 4321 preferably has a curved surround structure to improve the deformation range and return effect of the flexible connecting arm 4321. Specifically, the number of lower elastic sheets 432 may be two, three, four or more than four, and the multiple lower elastic sheets 432 are evenly arranged along the circumferential direction of the lens barrel 300. By providing multiple lower elastic sheets 432 respectively connected to the lens barrel 300 and the support frame 200, the focus recovery effect and reset stability of the focus component 410 can be improved.

[0042] Furthermore, the lens barrel 300 is provided with a fourth clearance groove 320, which is provided on the side facing the flexible connecting arm 4321 of the support frame 200, and the orthogonal projection of the flexible connecting arm 4321 on the support frame 200 at least partially overlaps with the fourth clearance groove 320.

[0043] In this embodiment, a fourth escape groove 320 is provided in the lens barrel 300 to cooperate with the flexible connecting arm 4321, so that when the lens barrel 300 moves relative to the support frame 200, the fourth escape groove 320 can avoid contact with the flexible connecting arm 4321, thereby preventing collision between the lens barrel 300 and the upper elastic sheet 431, improving the durability of the upper elastic sheet 431, and making the structure between the upper elastic sheet 431 and the support frame 200 more compact.

[0044] Referring to Figures 4 to 6, in one embodiment, a movable hole 211 is formed through the support frame 200, and the suspension wire 440 is installed through the movable hole 211 and installed at a distance from the inner wall of the movable hole 211.

[0045] By positioning the movable hole 211 to cooperate with the suspension wire 440, on the one hand, it is possible to prevent the lens barrel 300 from colliding with the suspension wire 440 during deformation, thereby improving the durability of the suspension wire 440; on the other hand, the combined structure of the suspension wire 440 and the support frame 200 becomes more compact, facilitating the miniaturization design of the lens module 10.

[0046] Furthermore, the upper elastic sheet 431 further includes a damping filler 441 , which is filled in the movable hole 211 and surrounds at least a portion of the suspension wire 440 .

[0047] By installing it in this manner, when the suspension wire 440 is deformed or displaced relative to the support frame 200, the damping filler 441 provides a damping effect to the suspension wire 440, thereby cushioning the relative displacement between the support frame 200, the lens barrel 300 and the base 120.

[0048] 4, 7 and 8, the image stabilization component 420 includes an image stabilization coil 421, an image stabilization magnet 422 and an image stabilization circuit board 423. The base 120 has an accommodating groove 121, the image stabilization coil 421 is installed at the bottom of the support frame 200, and the image stabilization magnet 422 is accommodated in the accommodating groove 121 and installed corresponding to the image stabilization coil 421.

[0049] In this embodiment, the number of image stabilization coils 421 is at least two, and the two image stabilization coils 421 cooperate with two image stabilization magnets 422 to drive support frame 200 along the X and Y directions in a plane perpendicular to the optical axis of lens barrel 300, thereby achieving the image stabilization function. If image stabilization component 420 includes multiple image stabilization coils 421, the multiple image stabilization coils 421 can be connected via image stabilization circuit board 423.

[0050] In one embodiment, the direction of the magnetic field lines of the image stabilization coil 421 is toward or away from the image stabilization magnet 422. In this case, when the image stabilization coil 421 is energized, a magnetic force is generated between the image stabilization coil 421 and the image stabilization magnet 422, and the image stabilization component 420 can realize the function of moving the support frame 200 in the X direction and / or the Y direction.

[0051] Furthermore, compared to the conventional lens module 10 in which a magnet is installed in a moving part, in the present invention, image stabilization magnet 422 is fixed within base 120 (corresponding to the fixed member) and focus coil 411 is fixed to upper shell 110, which effectively reduces the mass of support frame 200 and lens barrel 300 and reduces the driving force required to drive focus component 410 and image stabilization component 420 to move support frame 200 and lens barrel 300, thereby improving the movement accuracy of adjustment mechanism 400. At the same time, by installing image stabilization magnet 422 within base 120, the problem of image stabilization magnet 422 generating unnecessary attractive or repulsive forces on other moving components is avoided, thereby improving the control accuracy of lens module 10.

[0052] Specifically, as shown in FIG. 7, the support frame 200 further includes a fixed column 230, which is provided at the bottom of the frame body 210, and the image stabilization coil 421 is wound around the fixed column 230.

[0053] In this embodiment, the image stabilization coil 421 is arranged in cooperation with the fixed pillars 230, which facilitates the attachment and fixation between the image stabilization coil 421 and the frame body 210. Naturally, if there are two fixed pillars 230, the image stabilization coil 421 can be wound and connected to the two fixed pillars 230 in order, and the image stabilization coil 421 can have, for example, an arc-shaped or oval-arc-shaped cross section.

[0054] Specifically, as shown in FIG. 5, the frame insert 220 includes an insert connecting portion 221, an insert fixing portion 222, and an insert intermediate portion 223, the insert connecting portion 221 and the insert fixing portion 222 being respectively connected to opposite sides of the insert intermediate portion, and the insert intermediate portion 223 being bent from the insert fixing portion 222 toward the upper elastic sheet 431, the insert connecting portion 221 at least partially extending from the frame main body 210 and electrically connected to the upper elastic sheet 431, and the insert fixing portion 222 being at least partially exposed from the bottom surface of the frame main body 210 and electrically connected to the image stabilization circuit board 423, thereby realizing circuit conduction between the focus component 410, the image stabilization component 420, the elastic sheet structure 430, and the base 120.

[0055] In one embodiment, the base 120 has four base inserts 122, and the four base inserts 122 are electrically connected to four sets of stabilization coils 421 and focus coils 411 via four sets of elastic sheet structures 430. In this embodiment, the ICs of the two stabilization coils 421 of the focus component 410 and the stabilization component 420 are connected in parallel to the four base inserts 122, two of which are used for power supply (VCC) and ground (GND), and the other two are used to send control signals (including, but not limited to, analog signals and digital signals) to the two stabilization coils 421 and focus coil 411, respectively. At this time, the base 120 can turn on an external control circuit via the four base inserts 122. The overall structure is compact, making it easy to install the lens module 10 in an electronic device.

[0056] As shown in Figures 4 and 8, the focus component 410 further includes a focus IC module 414, which is connected to the focus circuit board 413 and electrically connected to the elastic sheet structure 410; the adjustment mechanism 400 further includes a sensing magnet 451, which is mounted on the support frame 200, the focus IC module 414 magnetically cooperates with the sensing magnet 451, and the focus IC module 414 is electrically connected to the focus coil 411, so that the focus IC module 414 can form a closed-loop control circuit.

[0057] In this embodiment, the focus IC module 414 includes a power supply IC for controlling the focus coil 411 and a Hall sensor coupled to the sensing magnet 451. This configuration allows the power supply IC and the Hall sensor to be combined to form a closed-loop control circuit, thereby improving the control accuracy of the focus component 410 and increasing the integration degree of the focus IC module 414 in the focus component 410, thereby improving the structural compactness of the lens module 10.

[0058] In some embodiments, as shown in FIG. 4 , the adjustment mechanism 400 further includes a position sensing component 450, where the position sensor signal is connected to the base 120, and the position sensor is used to obtain the relative position between the lens barrel 300 and the support frame 200.

[0059] In this embodiment, position sensing component 450 is independently installed and includes sensing magnet 451 and magnetic sensor 452, which magnetically cooperate with each other, with one of sensing magnet 451 and magnetic sensor 452 being installed on lens barrel 300 and the other being installed on support frame 200. Of course, in this embodiment, to achieve the functions of controlling and detecting position of focus coil 411, focus component 410 must be independently installed with a power supply IC corresponding to focus coil 411.

[0060] By installing it in this manner, when the lens barrel 300 moves relative to the support frame 200, the magnetic sensor 452 acquires a change in the magnetic signal of the sensing magnet 451 to determine the relative position between the lens barrel 300 and the support frame 200, thereby realizing the position feedback function of the adjustment mechanism 400. Specifically, the magnetic sensor 452 may be a Hall sensor. In other embodiments, the position sensing component 450 may be an infrared sensor or another type of position sensor, but this is not limited thereto.

[0061] As shown in Figures 4 and 8, the image stabilization component 420 further includes an image stabilization IC module 424, which is connected to the image stabilization circuit board 423 and is installed corresponding to the image stabilization magnet 422, and the image stabilization IC module 424 is electrically connected to the image stabilization coil 421.

[0062] In this embodiment, the image stabilization IC module 424 includes a power supply IC for controlling the image stabilization coil 421 and a Hall sensor coupled to the sensing magnet 451. This configuration allows the power supply IC and the Hall sensor to be combined to form a closed-loop control circuit, thereby improving the control accuracy of the focus component 410 and increasing the integration of the image stabilization IC module 424 in the focus component 410, thereby improving the structural compactness of the lens module 10.

[0063] Specifically, there may be two sets of image stabilization IC modules 424, each of which cooperates with two image stabilization magnets 422, thereby controlling the position between support frame 200 and base 120 in the X and Y directions perpendicular to the optical axis of lens barrel 300, and realizing the image stabilization function.

[0064] In a preferred embodiment, a hole corresponding to the image stabilization IC module 424 may be opened on the side of the support frame 200 facing the image stabilization circuit board 423, and the image stabilization IC module 424 is accommodated in this hole, thereby improving the compactness of the combination between the image stabilization circuit board 423 and the support frame 200.

[0065] Specifically, as shown in FIGS. 4 and 8, mounting groove 330 is provided on the outer peripheral wall of lens barrel 300, and focus coil 411 is wound around lens barrel 300 and installed within mounting groove 330.

[0066] By installing a mounting groove 330 in the lens barrel 300 and cooperating with the focus coil 411, the mounting groove 330 can position the mounting of the focus coil 411, thereby improving the installation convenience and installation accuracy of the focus coil 411.

[0067] Furthermore, as shown in FIGS. 3 and 8, an escape cavity 340 is opened on the side of the lens barrel 300 facing the focus magnet 412, and the focus magnet 412 is suspended within the escape cavity 340.

[0068] By installing it in this manner, when the lens barrel 300 and the support frame 200 move relative to the mounting structure 100, the focus magnet 412 can be accommodated in the escape cavity 340 of the lens barrel 300, and the escape cavity 340 can avoid the focus magnet 412, thereby preventing a collision between the focus magnet 412 and the lens barrel 300 and ensuring smooth adjustment and durability of the adjustment mechanism 400.

[0069] 3 to 7 and 9, in this embodiment, the suspension wires 440 in the upper elastic sheet 431 are electrically connected to the upper elastic sheet 431 and the base insert 122 in the base 120, and are electrically connected to an external circuit via the base insert 122. The upper elastic sheet 431 is electrically connected to the focus circuit board 413 and the frame insert 220 in the support frame 200, and one end of the frame insert 220 away from the upper elastic sheet 431 is electrically connected to the image stabilization circuit board 423. In this case, the image stabilization circuit board 423 is connected to multiple image stabilization coils 421, respectively, to realize the image stabilization adjustment function of the image stabilization component 420. The focus circuit board 413 is electrically connected to multiple sets of upper elastic sheets 431 and to the focus coils 411, thereby forming an electrical connection circuit for the lens module 10, making the overall structure compact and facilitating the placement of the lens module 10 in an electronic device.

[0071] In the electronic device of this embodiment, the lens module 10 of any of the above embodiments is installed.

This maximizes the internal space of the upper shell 110, allowing for a more compact structure between the lens barrel 300, the focus component 410, and the upper shell 110. This makes the overall structure of the lens module 10 more compact and easier to install in the electronic device. Furthermore, the elastic sheet structure 430 is electrically connected to the focus component 410 and the image stabilization component 420, thereby providing power and signal transmission functions for the lens module 10, further achieving the goal of optimizing the internal structure of the lens module 10. Specifically, the electronic device may include, but is not limited to, a tablet or smartphone.
