[0030] In the lens module 10 of this embodiment, the bending portion 111 spaced apart from the side wall portion 113 cooperates with the focusing coil 411 to maximize the use of the internal space of the upper shell 110 and make the structure between the focusing 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 reset component 430 is electrically connected to the focusing 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.

[0031] 1, 3, and 8, in one embodiment, a base insert 122 is embedded within the base 120, and the support frame 200 includes a frame body 210 and a frame insert 220. The base insert 122 embedded within the base 120 is connected to the reset component 430, and the frame insert 220 embedded within the frame body 210 is connected to the image stabilization component 420 and the reset component 430, respectively, thereby realizing circuit conduction between the image stabilization component 420 and the reset component 430. Furthermore, the overall strength of the base 120 and the support frame 200 can be improved, and the overall structure of the base 120 and the support frame 200 can be made more compact. In other embodiments, the base 120 and the support frame 200 can also implement electrical connection functions using external circuits, LDS (Laser Direct Structuring) technology, etc., but this is not limited thereto.

[0032] Specifically, the focus component 410 further includes a focus circuit board 413, which is electrically connected to the reset component 430, and the focus coil 411 is connected to the focus circuit board 413. In this embodiment, the anti-shake component 420 further includes an anti-shake circuit board 423, which is preferably an FPC, so that the thickness of the anti-shake circuit board 423 is thinner, and the anti-shake circuit board 423 is electrically connected to the reset component 430, thereby achieving the electrical connection function.

[0033] Specifically, referring to Figures 2 to 6 and 8, reset component 430 includes a first reset member 431, which includes a flexible structure 4311 and a suspension wire 4312, which is connected to lens barrel 300 and support frame 200 respectively, which support frame 200 is electrically connected to focus coil 411 and image stabilization component 420 respectively, which suspension wire 4312 is connected to flexible structure 4311 and base 120 respectively, and which suspension wire 4312 is electrically connected to base 120.

[0034] The first reset member 431 is formed by providing a flexible structure 4311 and connecting it to the suspension wire 4312. When the lens barrel 300 moves relative to the support frame 200 due to the driving action of the image stabilization coil 421, the flexible structure 4311 deforms to drive and reset the lens barrel 300. By providing a suspension wire 4312 connected to the support frame 200, the structure of the first reset member 431 and the support frame 200 can be made more compact, and the structure of the entire lens module 10 can be made more compact.

[0035] Specifically, referring to Figure 5, the flexible structure 4311 includes at least one first flexible arm 43111 and at least two first connection portions 43112, where the two first connection portions 43112 are respectively connected to the lens barrel 300 and the support frame 200, the first flexible arm 43111 is respectively connected to a plurality of first connection portions 43112, and the relative ends of the suspension wire 4312 are respectively electrically connected to the first connection portion 43112 and the base 120.

[0036] In this embodiment, the end of the suspension wire 4312 can be fixed to the first connecting portion 43112 by welding. To improve the fixing strength, it is preferable to cover the connection portion between the suspension wire 4312 and the first connecting portion 43112 with a certain amount of solder. When the lens barrel 300 moves relative to the support frame 200, the first flexible arm 43111 can deform and store elastic potential energy. When the driving force of the image stabilization component 420 is removed / or when the elastic force of the first flexible arm 43111 overcomes the force generated by the vibration of the electronic device, the first flexible arm 43111 can drive and reset the lens barrel 300. Using multiple first flexible arms 43111 to connect to two first connecting portions 43112 respectively improves the elastic force of the first flexible arms 43111, thereby improving the reset effect of the flexible structure 4311. 5, in a preferred embodiment, the extension path of first flexible arm 43111 preferably has a curved surround structure in order to improve the deformation range and reset effect of first flexible arm 43111. Specifically, the number of first reset members 431 may be two, three, four, or more than four, and the multiple first reset members 431 may be evenly arranged along the circumferential direction of lens barrel 300. By providing multiple first reset members 431 connected to lens barrel 300, the vibration isolation effect and reset stability of image stabilization component 420 can be improved.

[0037] Furthermore, the lens barrel 300 is provided with a first clearance groove 320, which is provided on the side of the lens barrel 300 facing the first flexible arm 43111, and the orthogonal projection of the first flexible arm 43111 on the lens barrel 300 at least partially overlaps with the first clearance groove 320.

[0038] In this embodiment, the lens barrel 300 is provided with a first escape groove 320 which cooperates with the flexible structure 4311 so that when the lens barrel 300 moves and deforms relative to the support frame 200, the first escape groove 320 can avoid the first flexible arm 43111, thereby preventing a collision between the lens barrel 300 and the first reset member 431, improving the durability of the first reset member 431, and making the structure between the first reset member 431, the support frame 200, and the lens barrel 300 more compact.

[0039] 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 43111, and the orthogonal projection of the first flexible arm 43111 on the support frame 200 at least partially overlaps with the second undercut groove 212.

[0040] In this embodiment, by providing a second escape groove 212 in the support frame 200 and cooperating with the flexible structure 4311, when the lens barrel 300 moves relative to the support frame 200, the second escape groove 212 can avoid contact with the first flexible arm 43111, thereby preventing collision between the support frame 200 and the first reset member 431, improving the durability of the first reset member 431, and making the structure between the first reset member 431 and the support frame 200 more compact.

[0041] Further, as shown in Figures 5 and 6, the flexible structure 4311 includes a second flexible arm 43113 and a second connection portion 43114, and the second flexible arm 43113 is respectively connected to the second connection portion 43114 and one first connection portion, and one end of the suspension wire 4312 remote from the base 120 is connected to the second connection portion 43114.

[0042] In this embodiment, the end of the suspension wire 4312 and the second connecting portion 43114 are welded together. To improve the strength of the connection between the suspension wire 4312 and the second connecting portion 43114, a certain amount of solder is preferably applied to the connecting portion between the suspension wire 4312 and the second connecting portion 43114. When the support frame 200 moves relative to the base 120, the second flexible arm 43113 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 43113 overcomes the force generated by the vibration of the electronic device, the second flexible arm 43113 can drive the support frame 200 to reset, thereby achieving the vibration-damping function. Using multiple second flexible arms 43113 to connect to the first connecting portion 43112 and the second connecting portion 43114, respectively, can increase the elastic force of the second flexible arm 43113, thereby improving the reset effect of the flexible structure 4311. In a preferred embodiment, in order to improve the deformation range and reset effect of the second flexible arm 43113, the extension path of the second flexible arm 43113 is preferably a curved surround structure.

[0043] 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 43113, and the orthogonal projection of the second flexible arm 43113 on the support frame 200 at least partially overlaps with the third undercut groove 213.

[0044] In this embodiment, by providing a third escape groove 213 in the support frame 200 and cooperating with the flexible structure 4311, when the lens barrel 300 moves relative to the support frame 200, the third escape groove 213 can avoid contact with the first flexible arm 43111, thereby preventing collision between the support frame 200 and the first reset member 431, improving the durability of the first reset member 431, and making the structure between the first reset member 431 and the support frame 200 more compact.

[0045] Further, referring to Figures 3, 5, 7, and 8, the reset component 430 further includes a second reset member 432, which is connected to the lens barrel 300 and the support frame 200, respectively, and the second reset member 432 is provided on the side of the support frame 200 away from the first reset member 431.

[0046] With this configuration, when the lens barrel 300 moves relative to the support frame 200, the two are connected via the installed second reset member 432, and the second reset member 432 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.

[0047] Specifically, as shown in FIG. 7 , the second reset member 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.

[0048] 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 reset. Using multiple flexible connecting arms 4321 and connecting them to the reset fixtures 4322 can increase the elastic force of the flexible connecting arms 4321, thereby improving the reset effect of the flexible structure 4311. 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 reset effect of the flexible connecting arm 4321. Specifically, the number of second reset members 432 may be two, three, four or more than four, and the multiple second reset members 432 are evenly arranged along the circumferential direction of the lens barrel 300. By providing multiple second reset members 432 connected to the lens barrel 300 and the support frame 200 respectively, the focus reset effect and reset stability of the focus component 410 can be improved.

[0049] Furthermore, the lens barrel 300 is provided with a fourth clearance groove 330, 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 330.

[0050] In this embodiment, by providing a fourth escape groove 330 in the lens barrel 300 and cooperating with the flexible connecting arm 4321, when the lens barrel 300 moves relative to the support frame 200, the fourth escape groove 330 can avoid the flexible connecting arm 4321, thereby preventing a collision between the lens barrel 300 and the first reset member 431, improving the durability of the first reset member 431, and making the structure between the first reset member 431 and the support frame 200 more compact.

[0051] Referring to Figures 4 to 6, in one embodiment, a movable hole 211 is formed through the support frame 200, and the suspension wire 4312 is installed through the movable hole 211 and installed at a distance from the inner wall of the movable hole 211.

[0052] By positioning the movable hole 211 to cooperate with the suspension wire 4312, on the one hand, it is possible to prevent the lens barrel 300 from colliding with the suspension wire 4312 during deformation, thereby improving the durability of the suspension 4312; on the other hand, the combined structure of the suspension wire 4312 and the support frame 200 becomes more compact, facilitating the miniaturization design of the lens module 10.

[0053] Furthermore, the first reset member 431 further includes a damping filler 4313 , which is filled in the movable hole 211 and surrounds at least a portion of the suspension wire 4312 .

[0054] By installing in this manner, when the suspension wire 4312 is deformed or displaced relative to the support frame 200, the damping filler 4313 provides a damping effect to the suspension wire 4312, thereby buffering the relative displacement between the support frame 200, the lens barrel 300 and the base 120.

[0056] In this embodiment, the lens barrel 300 is provided with a movable groove 340 that cooperates with the bent portion 111 of the upper shell 110, so that the overall structure between the upper shell 110 and the lens barrel 300 can be made more compact.

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.

[0060] In one embodiment, the direction of the magnetic field lines of the image stabilization coil 421 is toward the image stabilization magnet 422 or away from the image stabilization magnet 422. In this case, when the image stabilization coil 421 is energized, the image stabilization coil 421 generates a magnetic force with 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.

[0063] 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 first reset member 431, the insert connecting portion 221 at least partially extending from the frame main body 210 and electrically connected to the first reset member 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 reset component 430, and the base 120.

[0064] 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 through four sets of reset components 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 through the four base inserts 122.

This maximizes the internal space of the upper housing 110, thereby making the structure between the focus component 410 and the upper housing 110 more compact. This makes the overall structure of the lens module 10 more compact and easier to install in the electronic device. Furthermore, the reset component 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, 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.
