Referring to fig. 1 to 9 of the drawings, a camera module with a split lens according to a preferred embodiment of the present invention will be disclosed and described in the following description, wherein the camera module includes a photosensitive assembly 10 and an integrated lens assembly 20 disposed on a photosensitive path of the photosensitive assembly 10.

Specifically, referring to fig. 5 to 9, the photosensitive assembly 10 includes an assembly circuit board 11, a photosensitive chip 12, and a lens holder 13. The photosensitive chip 12 is disposed on the component circuit board 11, for example, in some specific examples, the photosensitive chip 12 may be mounted on the component circuit board 11, and the photosensitive chip 12 and the component circuit board 11 are connected by a wire bonding process to dispose the photosensitive chip 12 on the component circuit board 11; in other specific examples, the photosensitive chip 12 may be attached to the component circuit board 11 by a flip-chip process. The lens base 13 has a light-passing hole 131, the lens base 13 is disposed on the component circuit board 11, and the light-passing hole 131 of the lens base 13 corresponds to the photosensitive area of the photosensitive chip 12, so that the incident light passing through the light-passing hole 131 of the lens base 13 can reach the photosensitive area of the photosensitive chip 12. For example, in some specific examples, the lens holder 13 may be mounted to the component circuit board 11 to set the lens holder 13 to the component circuit board 11; in other specific examples, the lens holder 13 may be integrally formed with the component circuit board 11 to provide the lens holder 13 to the component circuit board 11.

Further, the photosensitive assembly 10 includes at least one electronic component 14, which may be a passive electronic component such as a capacitor, a resistor, or an inductor, or an active electronic component such as a diode, a memory chip, etc., and the electronic component 14 is mounted on the assembly circuit board 11. In the specific example in which the lens holder 13 is integrally formed on the component circuit board 11, the lens holder 13 may encapsulate the electronic component 14, so that the camera module does not need to reserve an avoidance space between the lens holder 13 and the electronic component 14, so as to be beneficial to reducing the size of the camera module.

Further, the photosensitive assembly 10 includes a filter element 15, where the filter element 15 is attached to the lens holder 13, and the lens holder 13 holds the filter element 15 on the photosensitive path of the photosensitive chip 12, so that the incident light needs to reach the photosensitive area of the photosensitive chip 12 after passing through the filter element 15 and the light passing hole 131 of the lens holder 13, where the incident light can be filtered by the filter element 15 when passing through the filter element 15, so as to be beneficial to improving the imaging quality of the imaging module. For example, in some specific examples, the filter element 15 is an infrared cut filter that is used to filter infrared light from the incident light.

The split lens assembly 20 is attached to the lens holder 13 of the photosensitive assembly 10, and the lens holder 13 supports the split lens assembly 20 to a photosensitive path of the photosensitive assembly 10.

Specifically, referring to fig. 2 to 9, the split lens assembly 20 includes a fixed lens group 21, an anti-shake lens group 22 and a focusing lens group 23, wherein the fixed lens group 21, the anti-shake lens group 22 and the focusing lens group 23 are sequentially disposed on the photosensitive path of the photosensitive assembly 10, and incident light reaches the photosensitive assembly 10 after sequentially passing through the fixed lens group 21, the anti-shake lens group 22 and the focusing lens group 23. Alternatively, in other examples of the split lens assembly 20 of the present invention, the split lens assembly 20 may also lack the fixed lens group 21, that is, the lens portion of the split lens assembly 20 is composed of the anti-shake lens group 22 and the focusing lens group 23, and the incident light reaches the photosensitive assembly 10 after passing through the anti-shake lens group 22 and the focusing lens group 23 in sequence. Wherein the anti-shake lens set 22 and the focusing lens set 23 define an optical axis.

The anti-shake lens group 22 is configured to move along a direction perpendicular to the optical axis to achieve an anti-shake function of the camera module, and the focusing lens group 23 is configured to move along the direction of the optical axis to achieve a focusing function of the camera module, wherein a movement process of the anti-shake lens group 22 and a movement process of the focusing lens group 23 are independent from each other. That is, the movement process of the anti-shake lens group 22 and the movement process of the focus lens group 23 do not affect each other.

It should be noted that the number of lenses of the fixed lens group 21, the number of lenses of the anti-shake lens group 22, and the number of lenses of the focusing lens group 23 are not limited in the image capturing module of the present invention, and are designed as needed.

Further, the split lens assembly 20 includes a driving unit 24, the driving unit 24 includes at least one driving magnet 241, an anti-shake driving portion 242, and a focusing driving portion 243, wherein the position of the driving magnet 241 is configured to be kept stationary relative to the fixed lens group 21, the anti-shake driving portion 242 includes an anti-shake carrier 2421 and at least one anti-shake coil 2422 disposed on the anti-shake carrier 2421, the anti-shake lens group 22 is disposed on the anti-shake carrier 2421, the anti-shake coil 2422 and the driving magnet 241 are disposed opposite to each other along the direction of the optical axis, when the anti-shake coil 2422 is powered, an electromagnetic field generated by the anti-shake coil 2422 and a magnetic field of the driving magnet 241 interact to drive the anti-shake carrier 2421 to drive the anti-shake lens group 22 in the direction perpendicular to the optical axis, so as to implement an anti-shake function of the focusing module, wherein the focusing driving portion includes a carrier 24231 and at least one coil 2431 disposed on the anti-shake carrier 2421, and a focusing function of the focusing module 2432 is disposed on the optical axis 2432, when the anti-shake coil 2422 is powered, the electromagnetic field generated by the anti-shake coil 2422 and the magnetic field of the driving magnet 241 interact to drive the anti-shake carrier 2421 in the direction perpendicular to the direction of the optical axis, so as to implement the anti-shake lens group 22 in the direction perpendicular to the direction of the optical axis, thereby realizing the anti-shake function. Along the optical axis direction, the anti-shake coil 2422 is located above the focusing coil 2432.

With respect to the focusing lens group 23 of the split lens assembly 20, the anti-shake lens group 22 of the split lens assembly 20 is disposed in front of the focusing lens group 23, it is understood that in the split lens assembly 20, the sensitivity of the lens group near the object side is higher than that of the lens group far away from the object side, the anti-shake lens group 22 is disposed in front of the focusing lens group 23 and the anti-shake coil 2422 is disposed above the focusing coil 2432, so that the anti-shake coil 2422 interacts with the driving magnet 241 to drive the anti-shake lens group 22 with higher sensitivity to move, thereby enabling the camera module to obtain better anti-shake effect. Meanwhile, the rear focusing lens group 23 may also have a larger moving space under the interaction of the focusing coil 2432 and the driving magnet 241, so as to meet the focusing requirement of a large stroke.

In the prior art, the focusing lens group 23 is located above and interacts with the driving magnet 241 through the focusing coil 2432 to move up and down to achieve the focusing function of the camera module, the anti-shake lens group 22 is located below and interacts with the driving magnet 241 through the anti-shake coil 2422 to achieve the anti-shake function of the camera module through translational motion, in other words, the anti-shake lens group 22 is located behind and the focusing lens group 23 is located in front in the prior art, which requires to reserve the moving distance of the focusing lens group 23 at the top of the split lens assembly 20 and prevent the contact safety distance between the focusing lens group 23 and the housing 26. It follows that the split lens assembly 20 of the prior art requires more space to be reserved at the top.

In contrast, in the technical solution of the present application, the front anti-shake lens set 22 and the rear focusing lens set 23 are arranged, that is, along the optical axis direction, the upper anti-shake coil 2422 interacts with the driving magnet 241 to drive the anti-shake lens set 22 to implement the anti-shake function of the camera module through translational motion, and the lower focusing coil 2432 interacts with the driving magnet 241 to drive the focusing lens set 23 to implement the focusing function of the camera module through up-down movement. In this way, the split lens assembly 20 only needs to reserve less space at the top for preventing interference between the anti-shake lens set 22 and the housing 26 due to touching. In the image capturing module of the present application, the anti-shake lens group 22 is disposed on the anti-shake carrier 2421, the anti-shake driving portion 242 and the driving magnet 241 cooperate to drive the anti-shake lens group 22 to move in a direction perpendicular to the optical axis, the focusing lens group 23 is disposed on the focusing carrier 2431, and the focusing driving portion 243 and the driving magnet 241 cooperate to drive the focusing lens group 23 to move in the direction of the optical axis, so that the anti-shake driving portion 242 and the driving magnet 241 cooperate to drive only the anti-shake lens group 22 to move, the anti-shake driving portion 243 and the driving magnet 241 cooperate to drive only the focusing lens group 23 to move, and the focusing lens group 23 has a larger stroke and reliability, and the focusing effect of the image capturing module is improved.

And, when the camera module needs to be anti-shake, the driving unit 24 only needs to drive the anti-shake lens group 22 to move, but does not need to drive other lens groups of the split lens assembly 20 to move, accordingly, when the camera module needs to be focused, the driving unit 24 only needs to drive the focusing lens group 23 to move, but does not need to drive other lens groups of the split lens assembly 20 to move, and because the driving unit 24 does not need to drive all lens groups to move, and does not need to drive the anti-shake lens group 22 and the focusing lens group 23 to move at the same time, the camera module can reduce the requirement on the driving force of the driving unit 24, so that the driving unit 24 can realize the anti-shake function and the focusing function of the camera module under the condition of providing lower driving force, which is beneficial to reducing the technical difficulty of the driving unit 24 and reducing the size of the driving unit 24, thereby reducing the overall size of the camera module.

In addition, the anti-shake driving part 242 and the driving magnet 241 are mutually matched to individually drive the anti-shake lens group 22 to move along the direction perpendicular to the optical axis, and the focusing driving part 243 and the driving magnet 241 are mutually matched to individually drive the focusing lens group 23 to move along the direction of the optical axis, so that not only can the crosstalk problem in the anti-shake and focusing process be completely eliminated, but also the weight of the individually driven lens group is lighter, so that the split lens assembly 20 obtains a better optical axis, which is important for improving the imaging quality of the camera module.

Further, the anti-shake lens group 22 is disposed in front and the focusing lens group 23 is disposed in rear, so that in assembling the split lens assembly 20, firstly, the focusing unit of the split lens assembly 20 composed of the focusing driving portion 243 and the focusing lens group 23 is assembled, and secondly, the anti-shake unit of the split lens assembly 20 composed of the anti-shake driving portion 242 and the anti-shake lens group 22 is assembled, and therefore, after the assembly of the focusing unit is completed, the anti-shake unit can be assembled after the assembly of the focusing unit is completed, and the influence of the poor focusing unit on the anti-shake unit is avoided.

In this example of the camera module of the present invention, referring to fig. 2 to 9, the anti-shake carrier 2421 has an anti-shake carrier through hole 24211, the anti-shake lens set 22 is disposed on the anti-shake carrier through hole 24211 of the anti-shake carrier 2421, and the anti-shake carrier 2421 surrounds the anti-shake lens set 22 to dispose the anti-shake lens set 22 on the anti-shake carrier 2421. The anti-shake lens group 22 and the anti-shake carrier 2421 may be bonded by glue so that the anti-shake lens group 22 and the anti-shake carrier 2421 form a single body.

The anti-shake coil 2422 is fixedly disposed on the lower surface of the anti-shake carrier 2421, and the anti-shake coil 2422 is located above the driving magnet 241, so that when the anti-shake coil 2422 is powered, the electromagnetic field generated by the anti-shake coil 2422 interacts with the magnetic field of the driving magnet 241 to drive the anti-shake carrier 2421 to drive the anti-shake lens set 22 to move in the direction perpendicular to the optical axis, so as to realize the anti-shake function of the camera module.

Referring to fig. 2 to 9, the anti-shake driving part 242 includes a circuit board 2423, the anti-shake coil 2422 is formed on the circuit board 2423, wherein the circuit board 2423 is fixedly attached to the lower surface of the anti-shake carrier 2421 to fixedly arrange the anti-shake coil 2422 on the lower surface of the anti-shake carrier 2421. Alternatively, in other examples of the camera module, the anti-shake coil 2422 is a planar coil, which is mounted on the wiring board 2423. Alternatively, in other examples of the camera module, the anti-shake coil 2422 is a wiring board type coil that is directly fixedly attached to the lower surface of the anti-shake carrier 2421.

In this specific example of the camera module of the present invention shown in fig. 1 to 9, the wiring board 2423 has a plate through hole 24231, the positions of the plate through hole 24231 of the wiring board 2423 and the positions of the anti-shake carrier through holes 24211 of the anti-shake carrier 2421 correspond to each other, wherein the number of the anti-shake coils 2422 is four, the four anti-shake coils 2422 are sequentially arranged on the wiring board 2423 around the optical axis of the split lens assembly 20, accordingly, the number of the driving magnets 241 is four, the four driving magnets 241 are sequentially arranged around the optical axis of the split lens assembly 20, and the positions of the four anti-shake coils 2422 and the positions of the four driving magnets 241 are one by one, so that the anti-shake driving portion 242 and the driving magnets 241 can be mutually engaged by controlling the power supply of the four anti-shake coils 2422, driving the anti-shake lens group 22 to move in a direction perpendicular to the optical axis to realize the camera module's anti-shake function.

Further, referring to fig. 4 to 9, the lower surface of the anti-shake carrier 2421 has a positioning collar 24212, the positioning collar 24212 integrally extends downward from the edge of the anti-shake carrier through hole 24211, and the positioning collar 24212 extends into the board through hole 24231 of the circuit board 2423, so that the circuit board 2423 is sleeved on the positioning collar 24212, wherein the positioning collar 24212 can position the circuit board 2423 to prevent the circuit board 2423 from translating relative to the anti-shake carrier 2421.

In this example of the camera module of the present invention, referring to fig. 2 to 9, the focus carrier 2431 has a focus carrier through hole 24311, the focus lens set 23 is disposed on the focus carrier through hole 24311 of the focus carrier 2431, and the focus carrier 2431 surrounds the periphery of the focus lens set 23 to dispose the focus lens set 23 on the focus carrier 2431. The focusing lens group 23 and the focusing carrier 2431 may be bonded by glue so that the focusing lens group 23 and the focusing carrier 2431 form a single body.

The focusing coil 2432 is fixedly disposed at a side of the focusing carrier 2431, and the focusing coil 2432 is located at an inner side of the driving magnet 241, so that when the focusing coil 2432 is powered, an electromagnetic field generated by the focusing coil 2432 interacts with a magnetic field of the driving magnet 241 to drive the focusing carrier 2431 to drive the focusing lens group 23 to move along an optical axis direction, so as to realize a focusing function of the camera module. That is, in this specific example of the image pickup module of the present invention, four driving magnets 241 are wound around the side of the focus carrier 2431, which is advantageous not only in reducing the height dimension of the image pickup module, but also in that the focusing coil 2432 and the anti-shake coil 2422 can share the driving magnets 241 to facilitate reducing the overall dimension of the image pickup module.

It should be noted that the specific manner in which the focusing coil 2432 is fixedly disposed at the side of the focusing carrier 2431 is not limited in the camera module of the present invention. For example, in the specific example of the camera module of the present invention shown in fig. 1 to 9, the focusing coil 2432 surrounds the focusing carrier 2431, for example, the wire for forming the focusing coil 2432 is directly wound on the side of the focusing carrier 2431, so that the focusing coil 2432 surrounds the periphery of the focusing carrier 2431.

Preferably, the focusing carrier 2431 has a focusing carrier groove 24312 at a side thereof, and the focusing coil 2432 is formed in the focusing carrier groove 24312 of the focusing carrier 2431, so that, on one hand, the focusing coil 2432 is prevented from falling off from the focusing carrier 2431 to ensure the reliability of the camera module, and on the other hand, the focusing coil 2432 is prevented from protruding out of the focusing carrier 2431 to be beneficial to reducing the length and width of the camera module.

Referring to fig. 1 to 9, the split lens assembly 20 includes a fixing base 25 and a housing 26, the fixing base 25 has a housing through hole 251, the housing 26 has a housing through hole 261, the fixing base 25 and the housing 26 are mounted to each other to form a receiving cavity 200 between the fixing base 25 and the housing 26, and the housing through hole 251 of the fixing base 25 and the housing through hole 261 of the housing 26 are respectively communicated with the receiving cavity 200. The driving magnet 241 is fixedly disposed on the fixing base 25 and is accommodated in the accommodating cavity 200 of the split lens assembly 20, and the fixed lens group 21 is fixedly disposed on the housing 26 and corresponds to the housing through hole 261 of the housing 26, such that the driving magnet 241 is configured to be stationary relative to the fixed lens group 21, wherein the anti-shake driving portion 242 and the anti-shake lens group 22 and the focus driving portion 243 and the focus lens group 23 are accommodated in the accommodating cavity 200 of the split lens assembly 20.

The fixing base 25 further comprises a base 252 and a base wall 253, wherein the base through hole 251 is formed in the base 252, wherein the base wall 253 integrally extends upwards from the peripheral edge of the base 252 to enclose a base cavity 254 of the fixing base 25 by the base wall 253 and define a base opening 255 communicated with the base cavity 254, and wherein the housing 26 is mounted on the base wall 253 in a manner of covering the base opening 255 to form the receiving cavity 200 of the split lens assembly 20 by the base cavity 254.

Further, referring to fig. 2-5, the seat wall 253 has at least one notch 2531, the housing 26 has at least one downwardly extending ear 262, and the ear 262 of the housing 26 extends into the notch 2531 of the seat wall 253 to complement the notch 2531 of the seat wall 253 such that the notch 2531 of the seat wall 253 is closed. In this specific example of the camera module of the present invention, the opposite sides of the seat wall 253 have one notch 2531, respectively, and correspondingly, the opposite sides of the housing 26 have one ear 262, respectively, and the two ears 262 of the housing 26 extend into the two notches 2531 of the seat wall 253, respectively, so as to supplement the two notches 2531 of the seat wall 253.

The driving magnet 241 is fixedly disposed on at least one of the inner wall of the base 252 and the inner wall of the base 253 of the fixing base 25, so as to fixedly dispose the driving magnet 241 on the fixing base 25 and accommodate the driving magnet 241 in the accommodating cavity 200 of the split lens assembly 20. For example, in a specific example of the camera module of the present invention, at least a portion of the driving magnet 241 and an inner wall of the base 252 are bonded by glue to fixedly dispose the driving magnet 241 on the base 252, and at least a portion of the driving magnet 241 and an inner wall of the base wall 253 are bonded by glue to fixedly dispose the driving magnet 241 on the base wall 253, such that the driving magnet 241 is fixedly disposed on the inner wall of the base 252 and the inner wall of the base wall 253 of the fixing base 25. Of course, in other examples of the present invention, the driving magnet 241 may be fixedly provided only to the base 252, or the driving magnet 241 may be fixedly provided only to the base wall 253.

Further, the inner wall of the seat wall 253 is provided with an insertion groove 2532, the size of which is matched with the size of the driving magnet 241, wherein the driving magnet 241 is inserted into the insertion groove 2532 of the seat wall 253, in such a way that, on one hand, the bonding surface between the driving magnet 241 and the seat body 252 is advantageously enlarged, so that the driving magnet 241 can be reliably fixed to the fixing seat 25, and on the other hand, the positions of the driving magnets 241 are moved outwards, so that a larger space is provided between the four driving magnets 241, and thus, not only can the focusing driving portion 243 have a larger design allowance, but also the focusing lens group 23 has a larger size, so as to meet the optical design requirement of the camera module.

The bottom of the notch 2531 of the fixed seat 25 is lower than the top of the driving magnet 241, or the bottom of the notch 2531 of the seat wall 253 is flush with the top of the driving magnet 241, that is, the bottom of the notch 2531 of the seat wall 253 is not higher than the top of the driving magnet 241, in other words, the top of the driving magnet 241 is not lower than the bottom of the notch 2531 of the seat wall 253. In this way, in assembling the split lens assembly 20, a spacer may be disposed above the driving magnet 241 and allowed to extend to the outside of the fixing base 25 through the notch 2531 of the base wall 253. It will be appreciated that since the bottom of the notch 2531 of the seat wall 253 is not higher than the top of the driving magnet 241, the gasket is supported only by the driving magnet 241, which is advantageous in ensuring the flatness of the gasket. When the anti-shake driving portion 242 is assembled, the spacer is positioned between the driving magnet 241 and the anti-shake driving portion 242 to control the distance between the driving magnet 241 and the anti-shake driving portion 242, specifically, the distance between the driving magnet 241 and the anti-shake coil 2422, by the spacer, thereby achieving a better anti-shake effect. It is understood that the distance between the driving magnet 241 and the anti-shake coil 2422 is too far, which affects the driving effect between the driving magnet 241 and the anti-shake coil 2422; the distance between the driving magnet 241 and the anti-shake coil 2422 is too short, and interference occurs when the driving magnet 241 and the anti-shake coil 2422 move relatively, so that the distance between the driving magnet 241 and the anti-shake coil 2422 is controlled to be consistent with the thickness dimension of the spacer, thereby avoiding the occurrence of the above problems. After the anti-shake driving portion 242 is assembled, the spacer may be pulled outward to be removed, and then the housing 26 may be mounted to the fixing base 25, and the two ears 262 of the housing 26 may be respectively inserted into the two notches 2531 of the base wall 253 to supplement the two notches 2531 of the base wall 253.

The specific manner in which the fixed lens group 21 is fixedly provided to the housing 26 and corresponds to the housing through hole 261 of the housing 26 is not limited in the image pickup module of the present invention. For example, in this specific example of the camera module of the present invention shown in fig. 1 to 9, the outer wall of the fixed lens group 21 and the inner wall of the housing 26 for forming the housing through hole 261 are bonded by glue to fixedly dispose the fixed lens group 21 to the housing 26 and correspond to the housing through hole 261 of the housing 26, so that the fixed lens group 21 can be sunk to facilitate reducing the height dimension of the camera module.

Referring to fig. 5 to 9, the anti-shake driving portion 242 is suspended in the accommodating cavity 200 of the split lens assembly 20, and since the anti-shake coil 2422 is disposed on the lower surface of the anti-shake carrier 2421 and above the driving magnet 241, when the anti-shake coil 2422 is powered to allow the anti-shake driving portion 242 to drive the anti-shake lens assembly 22 to move along the direction perpendicular to the optical axis, the anti-shake driving portion 242 does not touch the driving magnet 241, so that the anti-shake driving portion 242 can drive the anti-shake lens assembly 22 to have a larger stroke, thereby being beneficial to improving the anti-shake effect of the camera module.

Referring to fig. 2,3, 4 and 9, the split lens assembly 20 includes at least one anti-shake suspension unit 27, the anti-shake suspension unit 27 includes an anti-shake spring 271 and an elastic support 272, wherein the anti-shake spring 271 is disposed on the anti-shake carrier 2421 and protrudes from a peripheral wall of the anti-shake carrier 2421, a top of the elastic support 272 is fixedly disposed at a position of the anti-shake spring 271 protruding from a peripheral wall of the anti-shake carrier 2421, and a bottom of the elastic support 272 is fixedly disposed on the fixing base 25, such that the anti-shake suspension unit 27 is used for suspending the anti-shake driving portion 242 in the accommodating cavity 200 of the split lens assembly 20. When the anti-shake coil 2422 is powered, the anti-shake driving portion 242 moves in the housing cavity 200 of the split lens assembly 20 along the direction perpendicular to the optical axis in such a manner that the anti-shake spring 271 and the elastic support 272 deform, so as to implement the anti-shake function of the camera module.

In this specific example of the camera module of the present invention, the number of the anti-shake suspension units 27 is four, and the four anti-shake suspension units 27 suspend the anti-shake driving portion 242 in the receiving cavity 200 of the split lens assembly 20 at four corners of the anti-shake carrier 2421 and four corners of the fixing base 25, respectively, wherein the four anti-shake suspension units 27 cooperate with each other to prevent the anti-shake driving portion 242 from tilting, thereby preventing the anti-shake lens group 22 from tilting and ensuring the optical axis of the split lens assembly 20 to be stable.
