Naturally, the described embodiments are only a part, not all of the embodiments of the present invention. All other embodiments obtained by those skilled in the art without creative efforts based on the embodiments of the present invention are included within the protection scope of the present invention.

[0029] Referring to FIGS. 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 connected to each other. The upper shell 110 includes a bent portion 111, an intermediate shell 112, and a side wall portion 113 spaced apart from the bent portion 111 and connected in sequence. The base 120 is used for electrically connecting to an external circuit. The support frame 200 is suspended inside the mounting structure 100. The lens barrel 300 is suspended inside the support frame 200. The adjustment mechanism 400 includes a focus component 410, a shake correction component 420, and a reset component 430. The focus component 410 includes a focus coil 411 and a focus magnet 412. The focus coil 411 is wound around the lens barrel 300 and is suspended between the bent portion 111 and the side wall portion 113. At least a part of the focus magnet 412 is installed on the side of the side wall portion 113 facing the focus coil 411. The shake correction component 420 is connected to the base 120 and the support frame 200 respectively. The reset component 430 is connected to the mounting structure 100, the support frame 200, and the lens barrel 300 respectively, and is electrically connected to the focus component 410 and the shake correction component 420.

[0030] In the lens module 10 of this embodiment, by cooperating the bent portion 111 spaced apart from the side wall portion 113 with the focus coil 411, the internal space of the upper shell 110 can be utilized to the maximum extent, and the structure between the focus component 410 and the upper shell 110 can be made more compact. As a result, the overall structure of the lens module 10 can be made more compact, facilitating mounting on an electronic device. And by adopting the fact that the reset component 430 is electrically connected to the focus component 410 and the shake correction component 420, the power supply and signal transmission functions of the lens module 10 can be realized, further achieving the purpose of optimizing the internal structure of the lens module 10.

[0031] Referring to FIGS. 1, 3, and 8, in one embodiment, a base insert 122 is embedded inside a base 120, and the support frame 200 includes a frame body 210 and a frame insert 220. By connecting the base insert 122 embedded in the base 120 to a reset component 430 and connecting the frame insert 220 embedded in the frame body 210 to a hand tremor correction component 420 and the reset component 430 respectively, circuit conduction between the hand tremor correction component 420 and the reset component 430 is realized. Moreover, the strength of the entire 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 can also adopt an external circuit, LDS technology (Laser Direct Structuring), etc. to realize the electrical connection function, but this is not uniquely limited here.

[0032] Specifically, the focus component 410 further includes a focus circuit board 413. The focus circuit board 413 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 hand tremor correction component 420 further includes a hand tremor correction circuit board 423. The hand tremor correction circuit board 423 is preferably an FPC. Thereby, the thickness of the hand tremor correction circuit board 423 becomes thinner, and the electrical connection function is realized through electrically connecting the hand tremor correction circuit board 423 to the reset component 430.

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

[0034] By installing the flexible structure 4311 and connecting it to the suspension wire 4312 to form the first reset member 431, when the lens barrel 300 moves relative to the support frame 200 due to the driving action of the shake correction coil 421, the flexible structure 4311 can be deformed to drive the lens barrel 300 to reset. By installing the suspension wire 4312 to be 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 compact.

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

[0036] In this embodiment, the end of the suspension wire 4312 can be fixed by welding it to the first connection part 43112. In order to improve the fixing strength, it is preferable to cover a certain amount of solder on the connection part between the suspension wire 4312 and the first connection part 43112. When the lens barrel 300 moves relative to the support frame 200, the first flexible arm 43111 can be deformed to store elastic potential energy. When the driving force of the hand shake correction 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 achieve the purpose of driving the lens barrel 300 to reset. When a plurality of first flexible arms 43111 are used and connected to the two first connection parts 43112 respectively, the elastic force of the first flexible arm 43111 can be improved, thereby improving the reset effect of the flexible structure 4311. As shown in FIG. 5, in a preferred embodiment, in order to improve the deformation range and reset effect of the first flexible arm 43111, the extending path of the first flexible arm 43111 preferably has a curved surrounding structure. Specifically, the number of the first reset members 431 may be two, three, four or more than four. The plurality of first reset members 431 are evenly arranged along the circumferential direction of the lens barrel 300. By providing a plurality of first reset members 431 connected to the lens barrel 300, the anti-vibration effect and reset stability of the hand shake correction component 420 can be improved.

[0037] Furthermore, a first escape groove 320 is provided in the lens barrel 300. The first escape groove 320 is provided on the side of the lens barrel 300 facing the first flexible arm 43111, and at least a part of the orthographic projection of the first flexible arm 43111 on the lens barrel 300 overlaps with the first escape groove 320.

[0038] In the present embodiment, by providing a first relief groove 320 in the lens barrel 300 and cooperating with the flexible structure 4311, when the lens barrel 300 moves and deforms with respect to the support frame 200, the first relief groove 320 can avoid the first flexible arm 43111. Thereby, the collision between the lens barrel 300 and the first reset member 431 is prevented, the durability of the first reset member 431 is improved, and the structure among the first reset member 431, the support frame 200, and the lens barrel 300 becomes more compact.

[0039] In one embodiment, a second relief groove 212 is provided in the support frame 200. The second relief groove 212 is provided on the side of the support frame 200 facing the first flexible arm 43111, and at least a part of the orthographic projection of the first flexible arm 43111 on the support frame 200 overlaps with the second relief groove 212.

[0040] In the present embodiment, by providing a second relief groove 212 in the support frame 200 and cooperating with the flexible structure 4311, when the lens barrel 300 moves with respect to the support frame 200, the second relief groove 212 can avoid the first flexible arm 43111. Thereby, the collision between the support frame 200 and the first reset member 431 is prevented, the durability of the first reset member 431 is improved, and the structure between the first reset member 431 and the support frame 200 becomes more compact.

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

[0042] In this embodiment, in order to improve the fixing strength between the end of the suspension wire 4312 and the second connection portion 43114 by welding and fixing them, it is preferable to cover a certain amount of solder on the connection portion between the suspension wire 4312 and the second connection portion 43114. When the support frame 200 moves relative to the base 120, the second flexible arm 43113 can be deformed to store elastic potential energy. When the driving force of the hand tremor correction 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 purpose of achieving a vibration isolation function. When a plurality of second flexible arms 43113 are used to connect to the first connection portion 43112 and the second connection portion 43114 respectively, the elastic force of the second flexible arm 43113 can be increased, 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 extending path of the second flexible arm 43113 is preferably a curved surrounding structure.

[0043] Referring to FIG. 6, in one embodiment, a third escape groove 213 is provided in the support frame 200. The third escape groove 213 is provided on the side of the support frame 200 facing the second flexible arm 43113, and at least a part of the orthographic projection of the second flexible arm 43113 on the support frame 200 overlaps with the third escape groove 213.

[0044] In this embodiment, by providing the 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 the first flexible arm 43111, thereby preventing the 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] Furthermore, referring to FIGS. 3, 5, 7, and 8, the reset component 430 further includes a second reset member 432. The second reset member 432 is connected to the lens barrel 300 and the support frame 200 respectively, and the second reset member 432 is provided on the side far from the first reset member 431 of the support frame 200.

[0046] With such a configuration, when the lens barrel 300 moves relative to the support frame 200, the two are connected via the installed second reset member 432. The second reset member 432 can apply an elastic driving force for reset to the lens barrel 300, and can also buffer 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 connection arm 4321 and at least two reset fixing parts 4322. The at least two reset fixing parts 4322 are respectively connected to the flexible connection arm 4321. Here, the two reset fixing parts 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 connection arm 4321 can deform to store elastic potential energy. When the driving force of the focus component 410 is removed or when the elastic force of the flexible connection arm 4321 overcomes the force generated by the vibration of the electronic device, the flexible connection arm 4321 can achieve the purpose of driving and resetting the lens barrel 300. When a plurality of flexible connection arms 4321 are used and connected to the reset fixing portion 4322 respectively, the elastic force of the flexible connection arm 4321 can be increased, thereby improving the reset effect of the flexible structure 4311. As shown in FIG. 7, in a preferred embodiment, in order to improve the deformation range and reset effect of the flexible connection arm 4321, the extending path of the flexible connection arm 4321 is preferably a curved surrounding structure. Specifically, the number of the second reset members 432 may be two, three, four or more than four. The plurality of second reset members 432 are evenly arranged along the circumferential direction of the lens barrel 300. By providing a plurality of second reset members 432 respectively connected to the lens barrel 300 and the support frame 200, the focus reset effect and reset stability of the focus component 410 can be improved.

[0049] Furthermore, a fourth escape groove 330 is provided in the lens barrel 300. The fourth escape groove 330 is provided on the side facing the flexible connection arm 4321 of the support frame 200, and at least a part of the orthographic projection of the flexible connection arm 4321 on the support frame 200 overlaps with the fourth escape groove 330.

[0050] In this embodiment, a fourth relief groove 330 is provided in the lens barrel 300 to cooperate with the flexible connection arm 4321. When the lens barrel 300 moves relative to the support frame 200, the fourth relief groove 330 can avoid the flexible connection 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 FIGS. 4 to 6, in one embodiment, a movable hole 211 is provided through the support frame 200, and the suspension wire 4312 is installed through the movable hole 211 and is installed at an interval from the inner wall of the movable hole 211.

[0052] By arranging 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 the deformation process, 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 miniaturized design of the lens module 10.

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

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

At this time, when the hand shake correction coil 421 is energized, the hand shake correction coil 421 generates a magnetic force by the hand shake correction magnet 422, and the hand shake correction component 420 can realize the function of moving the support frame 200 in the X direction and / or the Y direction.

[0061] Specifically, as shown in FIG. 7, the support frame 200 further includes fixed columns 230, the fixed columns 230 are provided at the bottom of the frame body 210, and the hand shake correction coils 421 are wound around the fixed columns 230 and installed.

[0062] In this embodiment, by arranging the hand shake correction coils 421 on the fixed columns 230 in cooperation, the attachment and fixation between the hand shake correction coils 421 and the frame body 210 can be facilitated. Naturally, when the number of the fixed columns 230 is two, the hand shake correction coils 421 can be wound around the two fixed columns 230 in sequence and connected, for example, a hand shake correction coil 421 having an arc-shaped or long arc-shaped cross section can be formed.

[0063] Specifically, as shown in FIG. 5, the frame insert 220 includes an insert connection portion 221, an insert fixing portion 222, and an insert intermediate portion 223. The insert connection portion 221 and the insert fixing portion 222 are respectively connected to opposite sides of the insert intermediate portion, and the insert intermediate portion 223 is bent from the insert fixing portion 222 toward the first reset member 431. The insert connection portion 221 extends at least partially from the frame body 210 and is electrically connected to the first reset member 431. The insert fixing portion 222 is at least partially exposed from the bottom surface of the frame body 210 and is electrically connected to the hand shake correction circuit board 423. Therefore, circuit conduction between the focus component 410, the hand shake correction component 420, the reset component 430, and the base 120 can be realized.

[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 hand shake correction coils 421 and focus coils 411 via four sets of reset components 430. In this embodiment, the ICs of the two hand shake correction coils 421 of the focus component 410 and the hand shake correction component 420 are respectively connected in parallel and connected to the four base inserts 122. Two of the four base inserts 122 are used for power supply (VCC) and ground (GND), and the other two base inserts 122 are used to transmit control signals (including, but not limited to, analog signals and digital signals) to the two hand shake correction coils 421 and the focus coil 411 respectively. At this time, the base 120 can be turned on by an external control circuit via the four base inserts 122, and since the overall structure is compact, it is easy to mount the lens module 10 on an electronic device.

[0065] Furthermore, as shown in FIG. 4, the adjustment mechanism 400 further includes a position sensing component 440. 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.

[0066] In one embodiment, the position sensing component 440 includes a sensing magnet 441 and a magnetic sensor 442. The sensing magnet 441 and the magnetic sensor 442 cooperate magnetically, with one of the sensing magnet 441 and the magnetic sensor 442 provided on the lens barrel 300 and the other of the sensing magnet 441 and the magnetic sensor 442 provided on the support frame 200.

[0067] By installing in this way, when the lens barrel 300 moves relative to the support frame 200, the magnetic sensor 442 obtains the change in the magnetic signal of the sensing magnet 441 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 442 may be a Hall sensor. In other embodiments, the position sensing component 440 may be an infrared sensor or other types of position sensors, but this is not uniquely limited here.

[0068] Specifically, as shown in FIGS. 4 and 8, an attachment groove 310 is provided on the outer peripheral wall of the lens barrel 300. The focus coil 411 is wound around the lens barrel 300 and installed in the attachment groove 310, and at least a part of the attachment groove 310 is located between the bending portion 111 and the side wall portion 113.

[0069] By providing the attachment groove 310 on the lens barrel 300 to cooperate with the focus coil 411, the installation convenience of the focus coil 411 can be improved, and at the same time, the structures of both can be made more compact, so that it can be understood that the lens module 10 has a more compact overall structure.

[0070] Further, the present invention provides an electronic device including a host and the lens module 10 in any of the above embodiments, and the lens module 10 is provided within the host.

[0071] In the electronic device of the present embodiment, by installing the lens module 10 in any of the above embodiments, the lens module 10 adopts a configuration in which the bent portion 111 installed at a distance from the side wall portion 113 cooperates with the focus coil 411, thereby maximizing the utilization of the internal space of the upper housing 110, making the structure between the focus component 410 and the upper housing 110 more compact. As a result, the overall structure of the lens module 10 becomes more compact, facilitating its installation in the electronic device. And by adopting a configuration in which the reset component 430 is electrically connected to the focus component 410 and the shake correction component 420, the power supply and signal transmission functions of the lens module 10 can be realized, further achieving the objective of optimizing the internal structure of the lens module 10. Specifically, the electronic device includes, but is not limited to, tablets and smartphones.
