Description

Optical path turning module and camera module Technical Field

[0001] The present application relates to the field of imaging, and more specifically to an optical path turning module and a imaging module. Background Art

[0002] Camera modules are an essential component of mobile electronic devices. With the advancement of camera module technology, user demands for these modules are becoming increasingly sophisticated and demanding. The development of camera products must not only meet high performance requirements but also meet the requirements of miniaturization and portability.

[0003] The periscope camera module is a product used for telephoto photography. An optical path deflection module (reflector, prism, etc.) is added in front of the lens module to deflect the vertically incident light beam into the camera module into a vertically emitted light beam. The beam then passes through the lens module and reaches the photosensitive chip, where it undergoes photoelectric conversion for imaging. The periscope camera module folds the light path through the optical path deflection module, enabling long-focus photography while reducing the height of the camera module. The camera module can be converted from a vertical installation on an electronic device to a horizontal installation, thereby reducing the impact on the thickness of the electronic device.

[0004] Camera modules usually have autofocus (Auto FocuA, AF function) and optical image stabilization (Optical Image Atabilization, OIA function). The AF function is usually achieved by a motor driving the lens to move linearly along the optical axis. The OIA function is achieved by compensating for jitter displacement by the motor. Since the periscope camera module has a larger focal length to achieve longer-distance shooting, it usually has a larger body. The motor setting position and setting form of the periscope camera module will affect the overall size of the camera module. Improper setting can easily lead to the periscope camera module being too large.

[0005] The OIA function of the periscope camera module can be achieved by moving the lens module. However, the lens module usually includes a carrier and multiple lenses mounted on the carrier, making the lens module usually heavy. Moving the lens module requires a large thrust, which results in a large motor and higher power consumption. This easily leads to the periscope camera module being too large, which is not in line with the development trend of miniaturization.

Therefore, the above terms should not be understood as limiting the present invention.

[0059] It is to be understood that the term "one" should be understood as "at least one" or "one or more", that is, in one embodiment, the number of an element may be one, while in another embodiment, the number of the elements may be multiple, and the term "one" should not be understood as a limitation on the quantity.

[0060] This application provides a camera module comprising an optical path deflection module, a lens module, and a photosensitive module, arranged sequentially from the object side to the image side. The optical path deflection module deflects light from the object being measured from a first direction to a second direction. The photosensitive chip in the photosensitive module is arranged perpendicular to the second direction to receive light from the second direction. Thus, the camera module folds the optical path, resulting in a longer total length (TTL) of the optical lens and a smaller height.

[0061] 1 and 2 , the camera module includes a housing 10, a base 20, an optical path deflection module 30, and a lens module 40. The base 20 is adapted to accommodate the optical path deflection module 30 and the lens module 40, and the housing 10 is mounted to the base 20. The housing 10 is provided with a light entrance window 100, through which external light enters the camera module. The optical path deflection module 30 is positioned proximate to the light entrance window 100.

[0062] External light enters the camera module through the light entrance window 100 along a first direction. The optical path deflection module 30 is configured to deflect the light incident along the first direction into light emitted along a second direction. The lens module 40 is disposed on the light exit side of the optical path deflection module 30 to receive the light emitted by the optical path deflection module 30.

[0063] The camera module further includes a photosensitive module (not shown in the figure), which is arranged on the exit side of the lens module 40. The photosensitive module receives the light emitted by the lens module 40 and performs photoelectric conversion.

[0064] For ease of description, the camera module is defined as extending along a mutually perpendicular first axis Z, a second axis Y, and a third axis X. The camera module extends along the third axis X to define its width, along the second axis Y to define its length, and along the first axis Z to define its height (thickness). A first direction is parallel to the first axis Z, a second direction is parallel to the second axis Y, and a direction parallel to the third axis X is defined as a third direction.

[0065] The optical path turning module 30, the lens module 40 and the photosensitive module are assembled on the base 20 along the second axis Y. The base 20 includes a first part 21, a second part 22 and a third part 23 formed in sequence along the second axis Y. The first part 21 is suitable for accommodating the optical path turning module 30, the second part 22 is suitable for accommodating the lens module 30, and the photosensitive module is suitable for being installed on the third part 23. The first part 21, the second part 22 and the third part 23 can be implemented as independent components or as an integrated component, and this application does not limit this. The housing 10 covers the base 20 so that the internal structure is blocked and light enters the interior of the camera module through the light window 100.

[0066] First, the optical path turning module 30 provided by the present application is described with reference to FIG. 3 to FIG. 6C .

[0067] The optical path deflection module 30 includes an optical path deflection member 31, which deflects light incident along a first axis Z (a first direction) into light emitted along a second axis Y (a second direction). The optical path deflection member 31 may be a reflector or a prism that deflects the light path. For ease of description, this application uses an example in which the optical path deflection member 31 is implemented as a prism.

[0068] The optical path turning component 31 has a light incident surface 311, a light emitting surface 312 and a turning surface 313. The turning surface 313 connects the light incident surface 311 and the light emitting surface 312. The light incident surface 311 and the light emitting surface 312 are connected. The light incident surface 311 intersects with the first axis Z, and the light emitting surface 312 intersects with the second axis Y. The turning surface 313 extends at a certain angle relative to the first axis Z and the second axis Y, and also has a certain inclination angle relative to the third axis X (third direction).

[0069] The light incident along the first axis Z enters the light path turning component 31 from the light incident surface 311 , reaches the turning surface 313 , and is turned by the turning surface 313 . The projection direction of the light is turned to be emitted from the light emitting surface 312 along the second axis Y.

[0070] When the camera module captures an image, the image may become blurred due to user hand shaking or when the captured image is a moving image. Therefore, a movable component is set in the optical path turning module 30 to correct the image. According to the jitter generated by the optical path turning component 31, the movable component carries the optical path turning component 31 to generate a corresponding displacement to compensate for the jitter and realize the OIA function.

[0071] Preferably, the optical path deflection module 30 rotates about a first rotation axis 301 and a second rotation axis 302, respectively aligning the optical path deflection member 31 with the first and second rotation axes 301 and 302 as centers. This compensates for shake displacement in two directions, suppressing image blur and producing higher-quality images compared to camera modules that only provide anti-shake in one direction. The first rotation axis 301 is perpendicular to the first and second directions, extending along the third axis X, while the second rotation axis 302 is parallel to the first direction, extending along the first axis Z. Furthermore, the optical path deflection member 31 performs pitch motion around the first rotation axis 301 and yaw motion around the second rotation axis 302.

[0072] The optical path deflection module 30 includes a first movable member 32, which is movably mounted on the base 20 and positioned within the interior space defined by the first portion 21. The first movable member 32 rotates about the first axis Z and the third axis X to support the optical path deflection member 31 in rotating about the first axis Z and the third axis X, thereby performing image correction.

[0073] The first movable member 32 carries the optical path deflecting member 31. The first movable member 32 has an inclined surface. The optical path deflecting member 31 is assembled on the first movable member 32, and the deflecting surface 313 abuts against the inclined surface.

[0074] Specifically, the first movable member 32 includes a bearing portion 321, a back portion 322, side portions 323, and a bottom portion 324. The bearing portion 321 and the back portion 322 are disposed opposite each other along the second axis Y. The side portions 323 are disposed on opposite sides of the bearing portion 321 and the back portion 322 along the third axis X. The bottom portion 324 is formed as the bottom of the bearing portion 321 along the first axis Z. The bottom portion 323 faces the bottom of the base 20.

[0075] More preferably, the first movable member 32 is integrally formed to reduce assembly difficulty.

[0076] The supporting portion 321 has a supporting surface 3211 that obliquely intersects the first axis Z, the second axis Y, and the third axis X. The turning surface 313 of the optical path turning member 31 abuts against the supporting surface 3211. Side portions 323 are formed on either side of the supporting portion 321 along the third axis X, and the optical path turning member 31 is clamped between the opposing side portions 323 along the third axis X.

[0077] The first movable component 32 further includes a positioning portion 325, which extends from the end of the side portion 323 relative to the back portion 322 along the third axis X and toward the supporting portion 321. After the optical path turning component 31 is assembled on the first movable component 32, the positioning portion 325 is located on the output side of the optical path turning component 31, contacts the output surface 312 along the second axis Y, and is located at the edge of the output surface 312.

[0078] In other words, the positioning portion 325 is formed to bend and extend from the side portion 323 to face the supporting portion 321 along the second axis Y, and is located at edges of both sides of the emission surface 312 of the optical path turning component 31 .

[0079] The optical path turning member 31 is abutted against the supporting portion 321 and the positioning portion 325 along the second axis Y to prevent the optical path turning member 31 from falling off the first movable member 32 , so that the optical path turning member 31 can be firmly mounted on the first movable member 32 .

[0080] The optical path deflection module 30 further includes a first drive mechanism 33, which drives the first movable member 32 to carry the optical path deflection member 31 and rotate about the first rotation axis 301. Furthermore, the first drive mechanism 33 is disposed on at least one side of the first movable member 32 along the second axis Y. The first drive mechanism 33 drives the first movable member 32 to move along the second axis Y and further rotate about the third axis X. The first drive mechanism 33 is arranged in a direction orthogonal to the second rotation axis 302 and the first rotation axis 301.

[0081] The first driving mechanism 33 includes a first actuating unit 331 and a first transmission unit 332 , and the first actuating unit 331 and the first transmission unit 332 are arranged along the second axis Y.

[0082] In a preferred embodiment of the present application, the first driving mechanism 33 is disposed on one side of the back portion 322 of the first movable member 32 along the second axis Y. The back portion 322 is provided with a first movable mounting portion 3221, and the base 20 is provided with a first base mounting portion 2101. The first movable mounting portion 3221 and the first base mounting portion 2101 are adjacent to each other along the second axis Y. One of the first actuating unit 331 and the first transmission unit 332 is disposed on the first movable mounting portion 3221, and the other is disposed on the first base mounting portion 2101, so as to be adjacent to each other along the second axis Y.

[0083] Furthermore, the side wall of the base 21 facing the back portion 322 is perforated to form a first base mounting portion 2101, to which the first actuating unit 331 is mounted. The surface of the back portion 322 facing the base 21 is grooved to form a first movable mounting portion 3221, to which the first transmission unit 332 is mounted. This arrangement avoids increasing the size of the camera module.

[0084] In one driving embodiment, one of the first actuating unit 331 and the first transmission unit 332 is implemented as a coil, and the other is implemented as a magnet. As shown in Figures 3 and 4, the first actuating unit 331 is a coil, and the first transmission unit 332 is a magnet. When the coil is energized, the magnetic field generated by the magnet and the current in the coil interact to generate a Lorentz force, which drives the first movable member 32 to carry the optical path turning member 31 along the second axis Y and further rotate around the third axis X, causing the optical path turning member 31 to pitch and tilt, thereby achieving anti-shake of the camera module in one direction.

[0085] The optical path deflection module 30 includes a second movable member 34, which is movably mounted on the base 20 and positioned within the interior space defined by the first portion 21. The second movable member 34 is positioned between the first movable member 32 and the base 20 along the first axis Z. The second movable member 34 supports the first movable member 32 in rotation about the first axis Z, causing the optical path deflection member 31 to yaw, thereby achieving anti-shake for the camera module in the other direction.

[0086] In a preferred embodiment of the present application, the second movable member 34 is disposed within the bottom 324 of the first movable member 32. The first movable member 32 is movably mounted on the second movable member 34 along the first axis Z. The second movable member 34 is built into the first movable member 32 to avoid increasing the size of the optical path deflection module 30 along the first axis Z.

[0087] The optical path turning module 30 includes a second driving mechanism 35 , which drives the second movable member 34 to carry the first movable member 32 and the optical path turning member 31 to rotate around the second rotation axis 302 , thereby achieving the yaw motion of the optical path turning member 31 .

[0088] The second drive mechanism 35 is arranged in a direction that intersects with the first drive mechanism 33 to avoid increasing the size of the optical path deflection module 30 by being arranged in the same direction. Both directions are perpendicular to the second rotation axis 302. The second drive mechanism 35 is arranged in a direction parallel to the first rotation axis 301.

[0089] Furthermore, the second driving mechanism 35 is mounted on at least one side of the first movable member 32 along the third axis X to drive the first movable member 32 to move along the third axis X. Furthermore, the second movable member 34 guides the first movable member 32 to rotate around the first axis Z.

[0090] The second driving mechanism 35 includes a second actuating unit 351 and a second transmission unit 352. The first actuating unit 351 and the second transmission unit 352 are adjacently arranged along the third axis X and are arranged on at least one side of the first movable member 32 on the third axis X. The first actuating unit 351 and the second transmission unit 352 interact with each other to generate a driving force to drive the first movable member 32 to move along the third axis X.

[0091] The second actuating unit 351 is mounted on the base 20, and the second transmission unit 352 is mounted on the first movable member 32. Specifically, the base 20 is provided with a second base mounting portion 2102, and the side portion 323 of the first movable member 32 is provided with a second movable mounting portion 3231. The second base mounting portion 2102 and the second movable mounting portion 3231 are adjacent to each other along the third axis X. The second actuating unit 351 is mounted on the second base mounting portion 2102, and the second transmission unit 352 is mounted on the second movable mounting portion 3231, so that the two are adjacent to each other along the third axis X.

[0092] In some examples of the present application, the second driving mechanism 35 is provided on both sides of the first movable member 32 along the third axis X. Correspondingly, the base 20 is provided with at least two second base mounting portions 2102 opposite to each other along the third axis X, and the side portion 323 is provided with at least two second movable mounting portions 3231 opposite to each other along the third axis X. At least two second actuating units 351 are mounted opposite to each other on the second base mounting portions 2102 of the base 20 along the third axis X, and at least two second transmission units 352 are mounted opposite to each other on the at least two second movable mounting portions 3231 of the first movable member 32 along the third axis X.

[0093] Furthermore, one of the second actuating unit 351 and the second transmission unit 352 is implemented as a coil, and the other is implemented as a magnet. When the coil is energized, the magnetic field generated by the magnet and the current in the coil interact to generate a Lorentz force, which drives the first movable member 32 to carry the optical path turning member 31 along the third axis X and further rotate around the first axis Z, achieving anti-shake in another direction.

[0094] The first drive mechanism 33 is disposed on at least one side of the first movable member 32 along the second axis Y, and the second drive mechanism 35 is disposed on both sides of the first movable member 32 along the third axis X. The first drive mechanism 33 and the second drive mechanism 35 are disposed around the first axis Z.

[0095] In a preferred embodiment of the present application, the first actuating element 331 of the first drive mechanism 33 and the second actuating element 351 of the second drive mechanism 35 are implemented as coils, which are mounted on the base 20 around the first axis Z. The first transmission element 332 of the first drive mechanism 33 and the second transmission element 352 of the second drive mechanism 35 are implemented as magnets, which are mounted on the first movable member 32 around the first axis Z. Therefore, the magnets that realize the movement of the first movable member 32 are both assembled on the first movable member 32, and the coils are both assembled on the base 20, reducing the difficulty of assembly.

[0096] The first movable member 32 and the second movable member 34 are arranged along the first axis Z, the first drive mechanism 33 is arranged along the second axis Y, and the second drive mechanism 35 is arranged along the third axis X. This avoids excessive size in one direction due to their being arranged in the same direction, facilitating miniaturization of the camera module. The second movable member 34 is built into the first movable member 32, avoiding any increase in the size of the optical path deflection module 30 along the first axis Z, thereby reducing the height of the camera module.

[0097] Next, the embodiments of the second movable member 34 and the first movable member 32 will be further described. Referring to FIG4 , the second movable member 34 includes a base 341 and a support arm 342. The base 341 extends in the XY plane, and the support arm 342 extends from the base 341 along the first axis Z. The support arm 342 extends protrudingly relative to the base 341.

[0098] In other words, the base 341 is plate-shaped, and the support arm 342 protrudes from the base 341 to be protrudingly located on a surface of one side of the base 341. The surface of the base 341 where the support arm 342 is located is defined as a first side surface 3411 of the base 341. The first side surface 3411 is opposite to the bottom 324 of the first movable member 32.

[0099] The bottom 324 of the first movable member 32 is provided with a receiving space 3240 suitable for receiving the second movable member 34 , so that the second movable member 34 is built into the first movable member 32 .

[0100] 5A , the bottom portion 324 has a bottom surface 3241 that intersects the first axis Z and extends in the XY plane. A receiving space 3240 is defined from the bottom surface 3241 along the first axis Z in a direction opposite to the support portion 321. The side portions 323 define the receiving space 3240 on both sides along the third axis X. In other words, the receiving space 3240 is formed by a recessed portion extending from the bottom portion 324 toward the support portion 321 along the first axis Z.

[0101] The receiving space 3240 forms a first receiving space 32401 and a second receiving space 32402 . The first receiving space 32401 and the second receiving space 32402 are arranged along the first axis Z. The second receiving space 32402 is further distributed from the first receiving space 32401 toward the supporting portion 321 .

[0102] Furthermore, the portion of the bottom portion 324 located at the lowest end along the first axis Z has a first bottom surface 32411. The plane on which the first bottom surface 32411 lies defines the boundary of the first receiving space 32401 on the bottom side along the first axis Z. The bottom portion 324 also has a second bottom surface 32412, which defines the boundary of the first receiving space 32401 on the top side along the first axis Z. The second bottom surface 32412 is recessed along the first axis Z toward the supporting portion 321 to form the second receiving space 32402, and a third bottom surface 32413 is formed. The third bottom surface 32413 defines the boundary of the second receiving space 32402 on the top side along the first axis Z.

[0103] That is, the bottom 324 of the first movable member 32 is designed as an inwardly recessed step-like structure, which is compatible with the structure of the second movable member 34 with a boss design, so that the second movable member 34 can be built into the first movable member 32 .

[0104] When the first movable member 32 and the second movable member 34 are assembled, the support arm 342 is accommodated in the second receiving space 32402, and the base 341 is accommodated in the first receiving space 32402. Referring to Figures 6A and 6B , the first bottom surface 32411 is adapted to face the bottom wall 213 of the base 20, the second bottom surface 32412 is adapted to face the first side surface 3411 of the base 341, and the third bottom surface 32413 is adapted to face the top surface 3421 of the support arm 342.

[0105] 6A , the bottom 324 is further provided with a positioning post 3242 , which extends along the first axis Z within the receiving space 3240 and protrudes relative to the bottom surface 3241 . Furthermore, the positioning post 3242 protrudes from the second bottom surface 32412 along the first axis Z to be distributed in the first receiving space 32401 .

[0106] The second movable member 34 is provided with a positioning hole 340. A positioning post 3242 cooperates with the positioning hole 340 to position and mount the second movable member 34 to the first movable member 32. The positioning post 3242 engages with the positioning hole 340, enabling the second movable member 34 and the first movable member 32 to move together, thereby supporting the movement of the optical path deflection member 31. Furthermore, the positioning hole 340 is defined in the base 341. Preferably, the positioning post 3242 is located in the direction in which the second rotation axis 302 extends. Accordingly, the positioning hole 340 is formed in the direction in which the second rotation axis 302 extends.

[0107] Next, the motion guidance structure of the optical path deflection module 30 of the present application is described, which guides the optical path deflection member 31 to perform anti-shake motion. The optical path deflection module 30 includes a first guide member 36, which is disposed between the first movable member 32 and the second movable member 34 and guides the movement of the first movable member 32. The first drive mechanism 33 drives the first movable member 32, and the first guide member 36 guides the first movable member 32 to rotate about the third axis X.

[0108] The first guide member 36 supports the first movable member 32 along the first axis Z, and the second movable member 34 supports the first guide member 36 along the first axis Z. The first guide member 36 supports the first movable member 32, forming a first movement gap 3601 between the first movable member 32 and the second movable member 34, allowing the first movable member 32 to move relative to the second movable member 34. The first guide member 36 reduces friction between the first movable member 32 and the second movable member 34, improving movement efficiency, and maintaining movement friction between the first movable member 32 and the second movable member 34.

[0109] The first movement gap 3601 is distributed between the first movable member 32 and the second movable space 34 along the first axis Z, so that the first movable member 32 can generate a pitch motion relative to the second movable member 34, that is, rotate around the third axis X.

[0110] The top end of the support arm 342 of the second movable member 34 is provided with a first receiving groove 3420, into which the first guide member 36 is mounted. A third receiving space 32403 is defined at the bottom 32402 of the first movable member 32, adapted to accommodate the first guide member 36. Furthermore, a groove is formed extending from the third bottom surface 32413 along the first axis Z toward the support portion 321 to form the third receiving space 32403. The third receiving space 32403, the second receiving space 32402, and the first receiving space 32401 are arranged along the first axis Z.

[0111] The second movable member 34 is assembled to the first movable member 32 , the support arm 342 extends into the second receiving space 32402 , and the first guide member 36 located at the top end of the support arm 342 is partially accommodated in the third receiving space 32403 .

[0112] A first movable space 360 ​​is defined between the inner wall surface defining the first receiving groove 3420 and the inner wall surface defining the third receiving space 32403 . The first guide member 36 moves in the first movable space 360 ​​to guide the movement of the first movable member 32 .

[0113] The portion of the first guide member 36 located within the first receiving groove 3420 abuts against the inner wall surface defining the first receiving groove 3420. The portion located within the third receiving space 32403 abuts against the inner wall surface defining the third receiving space 32403 along the second axis Y, thereby limiting translational movement of the first guide member 36 along the second axis Y. The remaining portion is located outside the first receiving groove 3420 and the third receiving space 32402, forming a first movement gap 3601 that allows the movement of the first movable member 32 along the second axis Y to be converted into rotation about the third axis X. Therefore, when the first driving mechanism 33 drives the first movable member 32 to move along the second axis Y, the first guide member 36 guides the first movable member 32 to rotate about the third axis X, thereby achieving pitch movement of the optical path deflection member 31.

[0114] In a preferred embodiment of the present application, the first guide member 36 is implemented as a ball bearing, which abuts against the inner wall surface defining the first receiving groove 3420 along the second axis Y and the third axis X, thereby rolling within the first receiving groove 3420. Therefore, when the first driving mechanism 33 generates a driving force along the second axis Y, the translational movement of the first movable member 32 along the second axis Y is restricted, and the first guide member 36 rolls, guiding the first movable member 32 to rotate about the third axis X.

[0115] Furthermore, the at least one first guide member 36 is abutted against an inner wall surface defining the at least one first movable space 360 ​​along the third axis X, thereby restricting displacement along the third axis X. That is, the movement of the at least one first guide member 36 located in the at least one first movable space 360 ​​is restricted to rolling motion around the third axis X. Consequently, when guiding the first movable member 32 to rotate around the third axis X, the first movable member 32 is not guided to generate displacement along the third axis X, rotational motion around the first axis Z, or the like.

[0116] Preferably, referring to the schematic diagrams of Figures 5B and 5C , two support arms 342 are provided, formed on the first side surface 3411 of the base 341 along the third axis X, and symmetrically arranged about the second rotation axis 302. The top surface 3421 of each support arm 342 defines a first receiving groove 3420A and 3420B, respectively. The bottom 324 of the first movable member 32 is provided with two third receiving spaces 32403, symmetrically arranged about the second rotation axis 302. The two support arms 342 face each other parallel to the first rotation axis 301.

[0117] The first receiving grooves 3420A, 3420B and the third receiving spaces 32403A, 32403B distributed on both sides of the second rotating shaft 302 cooperate with each other to define first movable spaces 360A, 360B distributed on both sides of the second rotating shaft 302, respectively accommodating the first guide members 36A, 36B.

[0118] The first guide member 36A located in the first movable space 360A is restricted to rolling motion. This means that when the first guide member 36 guides the first movable member 32 to rotate about the first rotation axis 301, the first movable member 32 is restricted from rotating about the second rotation axis 302. In other words, the first guide member 36 prevents the first movable member 32 from yaw motion during pitch motion, thereby improving anti-shake accuracy.

[0119] Specifically, the inner wall surfaces A11 defining the boundaries of the first receiving groove 3420A at both ends along the third axis X are inclined surfaces, each inclined at a predetermined angle in opposite directions relative to the first axis Z. Furthermore, the inner wall surfaces A12 defining the boundaries of the first receiving groove 3420A at both ends along the second axis Y are inclined surfaces, each inclined at a predetermined angle in opposite directions relative to the first axis Z. In particular, at least four supporting points, each opposing each other, are formed between the first receiving groove 3420A and the first guide member 36A along a direction orthogonal to the second rotation axis 302.

[0120] The inner wall surfaces A21 defining the third receiving space 32403 along the third axis X are inclined surfaces. The inner wall surfaces A21 at both ends are inclined at a predetermined angle in opposite directions relative to the first axis Z. The inner wall surfaces A22 defining the third receiving space 32403 along the second axis Y are also inclined surfaces, inclined at a predetermined angle in opposite directions relative to the first axis Z. Specifically, at least four contact points are formed between the third receiving space 32403A and the first guide member 36A, each of which is opposed to the first axis Z in a direction perpendicular to the second rotation axis 302.

[0121] The first guide member 32A abuts against the inner wall surface defining the first receiving groove 3420A and the third receiving space 32403A along the third axis X and the second axis Y, restricting the first guide member 32A to only rolling motion. Consequently, the first guide member 36A located in the first movable space 360A is restricted from rotating about the second rotation axis 302, thereby restricting the first guide member 36 from guiding the first movable member 32 to rotate about the second rotation axis 302.

[0122] In addition, the first guide member 36A in the first movable member 360A is abutted against the inner wall surface defining the first movable space 360A along the third axis X and the second axis Y, which also facilitates the positioning and installation of the first movable member 32, the first guide member 36 and the second movable member 34.

[0123] The movement of the first guide member 36B in the first receiving groove 3420B located on the other side of the second rotation axis 302 can be restricted to rolling or unrestricted. In one embodiment, the inner wall surfaces of the first receiving groove 3420B and the third receiving space 32403B defining the first movable space 360B can be configured similarly to the aforementioned first movable space 360A, first receiving groove 3420A, and third receiving space 32403A.

[0124] In one embodiment, the inner wall surfaces B11 defining the other side of the first receiving groove 3420B along the third axis X are vertical surfaces extending along the first axis Z. A certain gap may exist between the first guide member 36B and the inner wall surfaces B11 at both ends. The inner wall surfaces B12 defining the second side of the first receiving groove 3420B along the second axis Y are inclined surfaces, tilted at a predetermined angle in opposite directions relative to the first axis Z to limit the displacement of the first guide member along the second axis Y. At least two opposing support points are formed between the first receiving groove 3420B and the first guide member 36B in a direction orthogonal to the second rotation axis 302.

[0125] Correspondingly, the inner wall surfaces B21 defining the two end boundaries of the third receiving space 32403 along the third axis X are inclined surfaces, tilted at a predetermined angle in opposite directions relative to the first axis Z, to restrict the displacement of the first guide member 36B along the third axis X. The third receiving hole 32403B and the first guide member 36B form at least two opposing contact points perpendicular to the second rotation axis 302. The inner wall surfaces B22 defining the two end boundaries of the third receiving space 32403 along the second axis Y are vertical surfaces extending along the first axis Z. A certain gap may exist between the first guide member 36B and the inner wall surfaces B22 at the two ends.

[0126] Therefore, the first guide member 36B located in the first movable space 360B is abutted against at least a portion of the inner wall surface defining the first movable space 360B along the third axis X and the second axis Y, so as to be restricted from generating displacement movement along the third axis X and the second axis Y, thereby avoiding the first guide member 36B from generating yaw movement when guiding the first movable member 32 to perform pitch movement.

[0127] The first guide member 36B located in the first accommodating groove 3420B and the part of the inner wall surface that defines the first accommodating groove 3420B have a gap in at least one direction orthogonal to the second rotation axis 302, which facilitates the movable structures to cooperate with each other for assembly; similarly, the part of the first guide member 36B accommodated in the third accommodating space 32403 and the part of the inner wall surface that defines the third accommodating space 32403 have a gap in at least one direction orthogonal to the second rotation axis 302, which facilitates the movable structures to cooperate with each other for assembly.

[0128] In addition, the two relatively arranged inner wall surfaces (A11, A12, B11, B12, A21, A22, B21, B22) that define the two end boundaries of the first receiving groove 3420A, 3420B and the third receiving space 32403A, 32403B can be directly connected or connected through a bottom surface extending generally along the XY plane.

[0129] Next, embodiments of the second movable member 34 and the base 20 will be described with reference to FIG. 6A to FIG. 8 .

[0130] The sidewalls of the base 21 include a first sidewall 211 and a second sidewall 212. The first sidewall 211 and the back portion 322 of the first movable member 32 are adjacent to each other along the second axis Y. The second sidewall 212 is disposed opposite to each other along the third axis X and is adjacent to the side portions 323 of the first movable member 32. The base 21 includes a bottom wall 213, and the second movable member 34 is movably mounted on the bottom wall 213.

[0131] Furthermore, the bottom wall 213 is provided with a boss 214 , which is formed to protrude from the bottom 213 along the first axis Z and is distributed in the XY plane. The second movable member 34 is movably mounted on the boss 214 .

[0132] The optical path turning module 30 also includes a second guide member 37, which is assembled between the second movable member 34 and the base 20. The base 20 supports the second guide member 37 along the first axis Z. The second guide member 37 supports the second movable member 34 along the first axis Z. The second guide member 37 guides the second movable member 34 to rotate around the first axis Z, so that the optical path turning member 31 performs a yaw motion, thereby realizing anti-shake of the camera module in another direction.

[0133] The first guide member 36 and the second guide member 37 are arranged along the first axis Z, forming a two-layer motion guide structure intersecting the second rotation axis 302. Furthermore, when viewed from the first axis Z, the second axis Y, and the third axis X, the first guide member 36 and the second guide member 37 do not overlap.

[0134] Therefore, the optical path turning module 30 includes two layers of guiding members arranged along a first direction parallel to the incident direction of light, guiding the first movable member 32 to rotate around the first rotation axis 301, and guiding the second movable member 34 to drive the first movable member 32 to rotate around the second rotation axis 302, so that the optical path turning member 31 can perform pitch and yaw motions to achieve anti-shake in two directions.

[0135] Among them, the first guide member 36 closer to the optical path turning member 31 is used to guide the optical path turning member 31 to perform pitch movement, and the second guide member 37 closer to the base 20 is used to guide the optical path turning member 31 to perform yaw movement, so that the pitch movement and yaw movement can be performed simultaneously, and anti-shake in two directions can be achieved at the same time, thereby enhancing the image stabilization effect.

[0136] In addition, the first guiding member 36 and the second guiding member 37 are disposed in the space occupied by the optical path turning module 30 in the base 20 , thereby avoiding additional occupation of other space in the base 20 and improving the utilization of the internal space.

[0137] In other words, the projection area of ​​the first guide member 36 and the second guide member 37 onto the base 20 along the first direction is located within the projection area of ​​the first movable member 32 onto the base 20 along the first direction. Furthermore, the projection area of ​​the second movable member 34 onto the base 20 along the first direction is located within the projection area of ​​the first movable member 32 onto the base 20 along the first direction. This ensures that the anti-shake structure (including the movable structure and the guide structure) of the optical path deflection module 30 does not occupy additional space on the base 20, thereby improving the internal space utilization of the base 20. This design also allows for a larger optical path deflection module 30 to be installed, maximizing the internal space of the base 20, as required by design.

[0138] Specifically, the second guide member 37 supports the second movable member 34 , and a second movement gap 3701 is formed between the second movable member 34 and the base 20 , so that the second movable member 34 can move relative to the base 20 .

[0139] The second movable member 34 has a second side surface 3412, with the first side surface 3411 and the second side surface 3412 facing each other. A second receiving groove 3413 is defined in the second side surface 3412. The base 20 is provided with a third receiving groove 2141. The second guide member 37 is mounted in the third receiving groove 2141. A second movable space 370 is formed between the inner wall surfaces defining the second receiving groove 3413 and the inner wall surfaces defining the third receiving groove 2141.

[0140] The portion of the second guide member 37 located in the second accommodating groove 3413 is abutted against the inner wall surface defining the second accommodating groove 3413 along the second axis Y, and the portion located in the third accommodating groove 2141 is abutted against the inner wall surface defining the third accommodating groove 32141 along the second axis Y. Therefore, when the second guide member 37 is located in the second movable space 370, it is restricted from producing translational movement along the second axis Y, so that the translational movement of the second movable member 34 along the second axis Y is restricted.

[0141] Preferably, the second movable space 370 defines at least one arcuate channel in a plane perpendicular to the second rotation axis 302. The arcuate channels are distributed circumferentially around the second rotation axis 302. The second guide member 37 moves along the arcuate channel. When the second drive mechanism 35 drives the first movable member 32, the second movable member 34 is driven, causing the second guide member 37 to move along the arcuate channel. This in turn guides the second movable member 34 to carry the first movable member 32 along the arcuate channel, causing the optical path deflection member 31 to rotate about the second rotation axis 302.

[0142] Specifically, the second receiving groove 3413 forms a first arc-shaped groove extending in an arc shape in the XY plane. The first arc-shaped groove extends around the first axis Z and along the third axis X in a curved manner.

[0143] The second driving mechanism 35 generates a driving force along the third axis X, driving the first movable component 32 to move along the third axis X. The second movable component 34 moves together with the first movable component 32. The second guide component 37 moves along the first arc-shaped groove around the first axis Z, thereby causing the second movable component 34 to carry the first movable component 32 and the optical path turning component 31 to rotate around the first axis Z.

[0144] The number of the third receiving grooves 2141 is one or more. Preferably, the plurality of third receiving grooves 2141 are distributed around the first axis Z. The plurality of third receiving grooves 2141 are distributed along the circumference of the same circle around the first axis Z. The center of the circle defined by the first arc-shaped channel of the second receiving groove 3413 and the center of the circle defined by the circumferential distribution trajectory of the plurality of third receiving grooves 2141 are aligned along the first axis Z.

[0145] In other words, when viewed from the first axis Z direction, the center and circumference of the circle defined by the first arc-shaped groove and the circle defined by the distribution trajectories of the plurality of third accommodating grooves 2141 overlap.

[0146] In some examples of the present application, the second guide member 37 is implemented as a ball bearing. The ball bearing assembled in the third receiving groove 2141 abuts against the surface defining the third receiving groove 2141 along the second axis Y and the third axis X. The ball bearing rolls in the third receiving groove 2141 and slides relative to the second receiving groove 3413. Thus, the ball bearing rolls and guides the second movable member 34 to rotate about the first axis Z along the trajectory of the first arcuate groove.

[0147] Furthermore, the third receiving groove 2141 includes at least one first groove 2141A and at least one second groove 2141B, each of which is suitable for receiving at least one second guide member 37 .

[0148] The second guide member 37 located in the first groove 2141A is abutted against the inner wall surface defining the first groove 2141A along the second axis Y and the third axis X, so that the translational movement of the second guide member 37 located in the first groove 2141A along the second axis Y and the third axis X is restricted.

[0149] The second guide member 37 located in the second groove 2141B abuts against an inner wall surface defining the second groove 2141B along the second axis Y to limit translational movement of the second guide member 37 along the second axis Y. The second groove 2141B extends a certain length along the third axis X, suitable for the second guide member 37 to move a certain distance along the second groove 2141B.

[0150] Furthermore, the second groove 2141B is distributed in an arc shape around the first axis Z, forming a second arcuate groove. When viewed from the first axis Z, the center and circumference of the circle defined by the first arcuate groove overlap with the circle defined by the second arcuate groove, and the second arcuate groove partially overlaps with the first arcuate groove. Furthermore, the second arcuate groove is located within the projection of the first arcuate groove in the first direction.

[0151] The second guide member 37 located in the second groove 2141B moves along the second arcuate groove about the first axis Z and slides relative to the second groove 2141B to guide the second movable member 34 to rotate about the first axis Z, thereby driving the first movable member 32 to carry the optical path deflection member 31 to rotate about the first axis Z. The second guide member 37 located in the first groove 2141A rolls to reduce friction and assist in the rotation of the second movable member 34.

[0152] That is to say, a first arc-shaped groove and a second arc-shaped groove distributed in two layers along the first axis Z are formed between the second movable component 34 and the base 20, for the second guide component 37 to slide, thereby improving the flexibility of the movement of the second guide component 37 and making the yaw anti-shake movement of the optical path turning module 30 around the first rotation axis more flexible.

[0153] In one embodiment of the present application, the second guide member 37 is implemented as a ball bearing, and there are at least three of them. At least one ball bearing is mounted in the second groove 2141A, and at least one ball bearing is mounted in the second groove 2141B. When viewed along the first axis Z, the second axis Y, and the third axis X, there is no overlap between the at least three ball bearings.

[0154] In a specific embodiment of the present application, the third receiving groove 2141 is formed by being recessed from the surface of the boss 214 along the first axis Z toward the bottom wall 213 of the base 20. The boss 214 has a certain thickness to allow for the formation of the groove.

[0155] According to another aspect of the present application, referring to Figures 9 to 11 of the specification, an embodiment of a camera module and its lens module 40 is described. The lens module 40 is disposed on the exit side of the optical path deflection module 30 along the second axis Y and receives light emitted from the optical path deflection module 30.

[0156] As shown in FIG9 , the lens module 40 includes a lens carrier 41 and a lens 42 . The lens 42 is installed in the lens carrier 41 . The lens carrier 41 carries the lens 42 to move for zooming and / or focusing.

[0157] The lens carrier 41 includes a carrier portion 411 and an opposing mounting portion 412. The carrier portion 411 is adapted to accommodate the lens 42, and the mounting portion 412 is adjacent to the base 20 along the third axis X. The lens 42 may include multiple lenses, through which light emitted from the optical path deflection module 30 passes before reaching the photosensitive module. The lens module 40 also includes a lens guide member 43, which is assembled to the base 20 and supports the movement of the lens carrier 41 and the lens 42.

[0158] The lens module 40 further includes a lens drive mechanism 44 that drives the lens carrier 41 to move the lens 42. The lens drive mechanism 44 is disposed on at least one side of the lens carrier 41 along the third axis X. In one example of the present application, the lens drive mechanism 44 is disposed on one side of the lens carrier 41 along the third axis X, i.e., the lens drive mechanism 44 is disposed on a single side.

[0159] The lens drive mechanism 44 includes a lens actuation unit 441 and a lens transmission unit 442. The lens actuation unit 441 and the lens transmission unit 442 are adjacently mounted on the lens carrier 41 and the base 20 along the third axis X, one of which is mounted on the lens carrier 41, and the other of which is mounted on the base 20. Schematically, the lens actuation unit 441 is mounted on the base 20, and the lens transmission unit 442 is mounted on the mounting portion 412 of the lens carrier 41.

[0160] In one embodiment of the present application, one of the lens actuation unit 441 and the lens transmission unit 442 is implemented as a coil, and the other is implemented as a magnet, so that the interaction between the magnetic field and the current generates a Lorentz force to drive the movement of the lens carrier 41. In other embodiments of the present application, the lens actuation unit 441 and the lens transmission unit 442 can be implemented as a piezoelectric drive mechanism.

[0161] The second portion 22 of the base 20 is mounted with the lens module 40 and includes second portion side walls 221 opposite to each other along the third axis X and a second portion bottom wall 222 distributed along the XY plane. The driving guide member 43 is assembled to the second portion bottom wall 222 of the base 20 to support the lens module 40 along the first axis Z direction.

[0162] The lens carrier 41 is provided with a first guide groove 410, which is formed at the bottom of the lens carrier 41 and is opposite to the bottom wall of the base 20. Furthermore, at least two first guide grooves 410 are respectively formed at the bottom of the mounting portions 412 on both sides, that is, the first guide grooves 410 are respectively defined at the bottom of the first mounting portions 412 on both sides.

[0163] The bottom wall 222 of the base 20 is provided with a second guide groove 220 adapted to receive the drive guide member 43. Furthermore, at least two second guide grooves 220 are distributed along the third axis X on the second portion of the bottom wall 222 of the base 20 to cooperate with the first guide grooves 410 on either side of the lens carrier 41, defining a third movable space 430.

[0164] The driving guide member 43 located in the third movable space 430 abuts against the inner wall surfaces defining the first guide groove 410 and the inner wall surfaces defining the second guide groove 220 along the third axis X, restricting translational movement of the driving guide member 43 along the third axis X. The driving guide member 43 abuts against the surface defining the second guide groove 220 along the second axis Y, restricting translational movement of the driving guide member 43 within the second guide groove 220 along the second axis Y. The first guide groove 410 has a track extending along the second axis Y, enabling relative movement along the second axis Y between the driving guide member 43 and the first guide groove 410.

[0165] Alternatively, the driving guide member 43 is abutted against a surface defining the first guide groove 410 along the second axis Y, limiting translational movement of the driving guide member 43 in the first guide groove 410 along the second axis Y. The second guide groove 220 has a track extending along the second axis Y, so that relative movement along the second axis Y can occur between the driving guide member 43 and the second guide groove 220.

[0166] Therefore, the driving guide member 43 guides the lens carrier 41 to move along the second axis Y to perform focusing and / or zooming, thereby realizing the AF function and / or optical zoom.

[0167] In a preferred embodiment of the present application, the driving guide member 43 is implemented as a ball, so that the lens carrier 41 and the base 20 are connected by rolling friction, and the friction between the lens carrier 41 and the base 20 is reduced by the ball.

[0168] Furthermore, in one embodiment, the number of balls is implemented as three, with one ball being provided on one side and two balls being provided on the other side. Specifically, two balls can be provided on the side near the lens drive mechanism 44 and one ball on the other side. In one embodiment, the number of balls is implemented as three or more. It is understood that the specific number of balls can be designed according to specific needs.

[0169] In one embodiment of the present application, the base 20 is provided with a second portion boss 223 . The second portion boss 223 protrudes relative to the second portion bottom wall 222 and extends along the first axis Z and is distributed in the XY plane. The second receiving groove 220 is formed in the second portion boss 223 .

[0170] The base 20 also includes a stopper member 224 that limits the movement distance of the lens carrier 41 along the second axis Y. The stopper member 224 includes a metal portion 2241 and a buffer portion 2242. The metal portion 2241 extends along the second axis Y and is located at the top of the second portion sidewall 221 on the first axis Z. There are at least two buffer portions 2242, which are located opposite to each other along the second axis Y and are spaced apart from each other so as to be adjacent to the two ends of the lens carrier 41 formed along the second axis Y.

[0171] The number of the stop member 224 can be one, distributed on one side of the lens carrier 41, or at least two, opposite to each other along the third axis X, and distributed on both sides of the lens carrier 41 on the third axis X. At least two of the stop members 224 are installed on the top of the second side wall 221 on the first axis Z.

[0172] The lens carrier 41 can be driven by the lens driving mechanism 44 to move in two directions along the second axis Y, such as moving along the second axis Y toward the optical path turning module 30 side, and moving along the second axis Y toward the photosensitive module side.

[0173] The buffer portion 2242 extends along at least one side of the lens carrier 41 along the second axis Y, limiting the position of the lens carrier 41. The buffer portion 2242 limits the movement of the lens carrier 41 in at least one direction along the second axis Y, such as unidirectional movement along the second axis Y. At least two buffer portions 2242 are provided to limit the movement of the lens carrier 41 in two directions along the second axis Y, such as bidirectional movement along the second axis Y. When viewed along the second axis Y, the buffer portion 2242 and the lens carrier 41 overlap.

[0174] In other examples of the present application, the lens carrier 41 can be moved to perform optical image stabilization.

[0175] The camera module further includes a circuit assembly 50 , which is adapted to be electrically connected to an external circuit and to provide power to the camera module. The circuit assembly 50 includes a circuit board 51 , which is mounted on the base 20 .

[0176] Referring to the schematic diagram of Figure 3, a circuit board 51 is mounted on the base 20 around the side wall of the base 20. The circuit board 51 is distributed around the first axis outside the optical path deflection module 30, adjacent to the drive mechanism of the optical path deflection module 30, and can provide power to the drive mechanism. Furthermore, when the first actuating unit 331 and the second actuating unit 352 of the first drive mechanism 33 and the second drive mechanism 35 are implemented as coils and mounted on the side wall of the base 20 around the first axis Z, the coils are electrically connected to the circuit board 51. The circuit board 51 is arranged outside the side wall of the base 20 around the side wall, outside the coil.

[0177] The corresponding circuit component 50 is assembled according to the split or integrated design of the first part 21 and the second part 22 of the base 20, and a split circuit board 51 or an integrated circuit board 51 is set in the first part 21 and the second part 22 to supply power to the optical path turning module 30 assembled in the first part 21 and the lens module 40 assembled in the second part 22.

[0178] A circuit board 51 is also formed on the second portion sidewalls 221 of the second portion 22 of the base 20 on opposite sides along the third axis X. The circuit board 51 is electrically connected to the lens drive mechanism 44. When the lens actuation unit 441 and the lens transmission unit 442 of the lens drive mechanism 44 are respectively implemented as a coil and a magnet, the coil is mounted on the second portion sidewall 221, and the circuit board 51 is formed outside the coil and electrically connected to the coil. When the coil is energized, the current and the magnetic field of the magnet interact, generating a Lorentz force that propels the lens carrier 41.

[0179] Similarly, the circuit board 51 is also formed on the third portion side wall 231 of the third portion 23 of the base 20 to provide power to the photosensitive module assembled on the third portion 23 .

[0180] The circuit assembly 50 further includes a reinforcing plate 52, which is disposed on the outer surface of the circuit board 51. Furthermore, the reinforcing plate 52 is mounted on the sidewall of the base 20 around the first axis Z, located on the outer surface of the circuit board 51; alternatively, multiple reinforcing plates 52 are disposed on the sidewalls of the base 20 in different directions, located on surfaces of the circuit board 51 that are opposite to each other along the third axis X and on the surface that extends along the second axis Y.

[0181] According to one aspect of the present application, the guiding members described in the present application (the first guiding member 36, the second guiding member 37 and the driving guiding member 43) are used to guide the movement of the corresponding movable members (the first movable member 32, the second movable member 34 and the lens carrier 41), which are suitable for moving or deforming under the action of force to achieve motion guidance, and can be implemented as a rolling part, such as a spherical member, a cylindrical member, or as a sliding member, such as a slider, or as an elastic member, such as a spring.

[0182] According to another aspect of the present invention, the camera module further includes a traction member 38, which is disposed between the optical path deflection module 30 and the base 20 along the first axis Z to generate a traction force along the first axis Z to pull the optical path deflection module 30 toward the base 20. The optical path deflection module 30 is pressed toward the base 20 along the first axis Z.

[0183] Specifically, the traction member 38 includes a first traction member 381 and a second traction member 382. The first traction member 381 is disposed on the optical path deflection module 30, and the second traction member 382 is disposed on the bottom wall 213 of the base 20, located in the direction in which the first traction member 381 extends along the first axis Z. The first traction member 381 and the second traction member 382 generate a traction force along the first axis Z, causing the first movable frame 32 to be pulled toward the base 20 along the first axis Z. The base 20 supports the first movable member 32 along the first axis Z, and the second movable member 34 is clamped between the base 20 and the first movable member 32.

[0184] Furthermore, as shown in Figures 6C to 7B , a first pulling member 381 is disposed on the bottom 324 of the first movable member 32. Preferably, the first pulling member 38 is disposed on the positioning post 3242, such as by providing a groove in the positioning post 3242 for accommodating the first pulling member 38, or by providing the first pulling member 38 internally within the positioning post 3242. A second pulling member 382 is disposed at a corresponding position on the bottom wall 213, such as by providing a groove in the boss 214 for accommodating the second pulling member 382. Thus, by utilizing the design structure of the optical path deflection module 30 and the base 20, the pulling member 38 is internally disposed, avoiding the need for a separate design that would increase the size and facilitating assembly.

[0185] Specifically, as shown in FIG6C , the positioning post 3242 is provided with a receiving groove to accommodate the first pulling member 381. The positioning post 3242 is located in the direction of extension of the second rotation axis 302, and the positioning hole 3410 is located in the direction of extension of the second rotation axis 302, adjacent to the positioning post 3242 along the second rotation axis 302. The first pulling member 381 and the second pulling member 382 are arranged opposite each other along the second rotation axis 302. After the first movable member 32 and the second movable member 34 move, the first movable member 32 and the second movable member 34 can be pulled back to their initial positions by a pulling force, maintaining them centered around the second rotation axis 302.

[0186] The traction mechanism 38 is arranged on the inner side of the optical path turning module 30, and the driving mechanism of the optical path turning module 30 (including the first driving mechanism 33 and the second driving mechanism 35) is arranged on the outer side or outer surface of the optical path turning module 30 to avoid mutual interference between the traction mechanism and the driving mechanism and to prevent the traction mechanism from interfering with the image correction process.

[0187] Similarly, mutually attractive traction members are provided between the lens module 40 and the base 20. As shown in FIG9 , a third traction member 45 is provided on the bottom wall of the base 20. A fourth traction member (not shown) is provided at the bottom of the lens carrier 41. The third traction member 45 and the fourth traction member are adjacent to each other along the first axis Z, generating an attractive force parallel to the first axis Z, causing the lens carrier 41 to be attracted toward the base 20 along the first axis Z. The lens module 40 is configured to be pressed toward the base 20 along the first axis Z.

[0188] Among them, one of the first pulling member 381 and the second pulling member 382 can be implemented as a magnetic magnet, and the other can be implemented as a magnetic yoke, so that they interact to generate traction; one of the third pulling member 45 and the fourth pulling member can be implemented as a magnetic magnet, and the other can be implemented as a magnetic yoke, so that they interact to generate traction. In other examples of the present application, the aforementioned traction members can be implemented as elastic members such as tension springs.

[0189] According to another aspect of the present invention, in some examples of the present application, the transmission unit of the drive mechanism is implemented as a magnet, and a magnetic component 39 can be provided adjacent to the magnet to enhance the magnet's magnetic field. For example, as shown in FIG6C , the first transmission unit 332 is implemented as a magnet, and the magnetic component 39 is provided on one side of the magnet to enhance the magnet's magnetic field. Furthermore, the magnetic component 39 can be built into the first movable member 32, such as by being built into the first movable member 32 during the manufacturing process of the first movable member 32 through a molding process.

[0190] According to another aspect of the present invention, in some examples of the present application, the camera module further includes a position sensing component for sensing the displacement of the telephoto camera module to control the displacement of the optical path turning module 30 and improve the anti-shake effect. For example, when the transmission unit of the driving mechanism is implemented as a magnet, the actuating unit is implemented as a coil, the magnet is mounted on the first movable member 32, and the coil is mounted on the base 20, the transmission unit can be used as both a driving magnet and a position sensing magnet, a position sensor is provided at the coil, the magnet moves with the first movable member 32, and the position sensing magnet can detect the offset of the optical path turning module 30, so that the controller can control the driving mechanism to correct the position of the optical path turning module 30 and achieve anti-shake in two directions.

[0191] The position sensing component also includes a driver integrated circuit (IC) for providing a drive control signal to the coil. For example, the driver IC is disposed on the circuit board 51 or near the coil. The coil can be the coil of the first drive mechanism 33 and / or the second drive mechanism 35.

[0192] The lens driving mechanism 44 of the lens module 40 may also have a position sensing function, and closed-loop control is achieved by setting a position sensor. For example, a Hall sensor and a driver integrated circuit (IC) are set to detect and feedback the displacement of the lens module 40.

[0193] 8 and 9 , in one example of the present application, the base 20 is implemented as an integral structure, wherein the first portion 21, the second portion 22, and the third portion 23 are integrally formed. The base 20 further includes a spacer 24 to separate the first portion 21 and the second portion 22, and the second portion 22 and the third portion 23. The spacer 24 includes a first spacer 241 and a second spacer 242. The first spacer 241 is formed between the first portion 21 and the second portion 22, and the second spacer 242 is formed between the second portion 22 and the third portion 23.

[0194] Furthermore, the ends of the first side walls 211 opposite to each other on the third axis X and extending along the second axis Y are bent and extended a certain distance toward the third axis X to form two first spacers 241 opposite to each other along the third axis X. The first spacers 241 are formed between the optical path turning module 30 and the lens module 40 along the second axis Y. The light emitted from the optical path turning module 30 passes through the space between the first spacers 241 along the second axis Y and is incident on the lens module 40.

[0195] Similarly, the ends of the second portion of the sidewalls 221 extending along the second axis Y and opposite to each other on the third axis X are bent and extended a certain distance toward the third axis X to form two second spacers 241. The second spacers 241 are formed along the second axis Y between the lens module 40 and the photosensitive module. Light emitted from the lens module 40 passes through the space between the second spacers 241 and reaches the photosensitive module.

[0196] The sidewall of the base 20 forms a third portion sidewall 231 at the third portion 23. Two third portion sidewalls 231 extend integrally along the second axis Y from opposite ends of the second portion sidewall 221 along the third axis X. A photosensitive module receiving space 230 is defined between the third portion sidewalls 231 for mounting the photosensitive module.

[0197] Furthermore, the third portion 23 forms a window sidewall 232, which surrounds and defines at least one window 2300. The window sidewall 232 is formed on the light incident side of the third portion 23, surrounds the second axis Y, and extends along the first axis Z and the third axis X to define the window 2300. The window 2300 is orthogonal to the second axis Y. At least a portion of the photosensitive chip (not shown in the figure) of the photosensitive module is exposed at the window 2300 to receive light emitted from the lens module 40. The portion of the photosensitive chip exposed at the window 2300 is the imaging area, and the other portion is blocked by the window sidewall 232. The photosensitive chip is orthogonal to the second axis Y.
