Description

Technical Field

[0001] This invention relates to optical imaging devices, and more particularly to a driving assembly and a camera module. Background Technology

[0002] With the continuous development of technology, portable electronic devices such as smartphones have replaced digital cameras as the preferred choice for taking photos and videos in daily life. Against this backdrop, consumers have placed higher demands on the image quality of portable electronic devices. When using portable electronic devices to take photos or videos, consumers typically use a handheld method, meaning they hold the device to take pictures or videos using the camera module. Due to a lack of professional training, ordinary consumers are prone to handshakes when using portable electronic devices, which can easily cause the device to shake. This shaking is reflected in the image captured by the camera module, resulting in blurry images. Solving the shaking problem that ordinary consumers encounter when using portable electronic devices is a direction that the industry is dedicated to researching. Summary of the Invention

[0076] Refer to the accompanying drawings of the specification of this invention. Figures 1 to 6 A camera module according to a preferred embodiment of the present invention will be disclosed and described in the following description, wherein the camera module includes a driving component 10, a lens component 20 and a photosensitive component 30.

[0077] Specifically, the driving assembly 10 includes a stabilization fixing part 11, a stabilization movable part 12, and a stabilization driving part 13. The stabilization fixing part 11 has a receiving cavity 1101 and a top opening 1102 communicating with the receiving cavity 1101. The photosensitive component 30 is disposed in the stabilization movable part 12, the stabilization movable part 12 is suspended in the receiving cavity 1101 of the stabilization fixing part 11, and the top opening 1102 of the stabilization fixing part 11 corresponds to the photosensitive component 30. The stabilization driving part 13 is used to drive the stabilization movable part 12 to perform translational and / or rotational movements relative to the stabilization fixing part 11, so as to realize translational and / or rotational stabilization of the camera module. Furthermore, the anti-shake fixing part 11 includes a base 111 and a top cover 112, with a top opening 1102 formed in the top cover 112. The base 111 and the top cover 112 are fastened together to form the receiving cavity 1101 between the base 111 and the top cover 112. Thus, the receiving cavity 1101 formed between the base 111 and the top cover 112 communicates with the top opening 1102 formed in the top cover 112.

[0078] The movable anti-shake part 12 and the driving anti-shake part 13 are respectively housed in the receiving cavity 1101 of the fixed anti-shake part 11, so that the fixed anti-shake part 11 forms the appearance of the driving assembly 10. In this way, on the one hand, the fixed anti-shake part 11 can prevent the movable anti-shake part 12 and the driving anti-shake part 13 from being collided, so as to protect the movable anti-shake part 12 and the driving anti-shake part 13. On the other hand, the base 111 and the top cover 112 of the fixed anti-shake part 11 cooperate with each other to form a sealed receiving cavity 1101, so as to prevent dust and other contaminants from entering the receiving cavity 1101 of the fixed anti-shake part 11 and contaminating the photosensitive element 32 and reducing stray light.

[0079] Preferably, the base 111 and the upper cover 112 of the image stabilization fixing part 11 are made of metal to ensure the strength of the drive assembly 10. For example, the base 111 and the upper cover 112 of the image stabilization fixing part 11 can be made of non-magnetic stainless steel.

[0080] It is understood that when the camera module implements the image stabilization function, the base 111 and the upper cover 112 of the image stabilization fixing part 11 remain stationary so that the image stabilization fixing part 11 forms a stator.

[0081] Reference Appendix Figure 1The lens assembly 20 includes a lens carrier 21 and an optical lens 22 disposed on the lens carrier 21. The lens carrier 21 is attached to the upper cover 112 of the image stabilization fixing part 11 to maintain the optical lens 22 in the light-sensing path of the photosensitive component 30. In this way, the incident light, after being converged by the optical lens 22, can pass through the top opening 1102 of the image stabilization fixing part 11 and reach the photosensitive component 30.

[0082] It is worth mentioning that the type of lens carrier 21 is not limited in the camera module of the present invention; for example, in the case of an attached... Figures 1 to 6 In this specific example of the camera module shown, the lens carrier 21 is a drive carrier used to drive the optical lens 22 to move along the optical axis of the camera module to achieve zooming and / or focusing, or to drive the optical lens 22 to translate to achieve image stabilization. For example, the lens carrier 21 can drive the optical lens 22 by the interaction of a coil and a magnet. As another example, the lens carrier 21 can be, but is not limited to, a voice coil motor, a piezoelectric motor, or an SMA (Shape Memory Alloy) motor. Optionally, in other specific examples of the camera module of the present invention, the lens carrier 21 can be a lens barrel used to hold the optical lens 22 in the light-sensing path of the photosensitive component 30.

[0083] It is also worth mentioning that in some other specific examples of the camera module of the present invention, the lens assembly 20 may be without the lens carrier 21. In this case, the optical lens 22 is directly attached to the upper cover 112 of the image stabilization fixing part 11 and is held in the light-sensing path of the photosensitive component 30.

[0084] Continue to refer to the appendix Figures 1 to 6 The photosensitive component 30 includes a circuit board 31 and a photosensitive element 32 connected to the circuit board 31, wherein the circuit board 31 is disposed on the image stabilization movable part 12 to dispose the photosensitive component 30 on the image stabilization movable part 12.

[0085] The photosensitive component 30 further includes a series of electronic components 33, which may be, but are not limited to, passive components such as resistors, capacitors, and processors, wherein these electronic components 33 are mounted on the circuit board 31.

[0086] Additionally, the photosensitive component 30 may also include a filter, such as an infrared cut-off filter, which is held in the photosensitive path of the photosensitive element 32.

[0087] Reference Appendix Figures 1 to 3BThe circuit board 31 has two extension arms 311. These two extension arms 311 extend from opposite sides of the circuit board 31 through the connection point between the base 111 and the upper cover 112 to the outside of the anti-shake fixing part 11 and further upwards. This ensures stability and reduces resistance when the anti-shake movable part 12 is driven by the anti-shake driving part 13 to perform translational and / or rotational movements within the receiving cavity 1101 of the anti-shake fixing part 11. Optionally, the two extension arms 311 can extend from adjacent sides of the circuit board 31 through the connection point between the base 111 and the upper cover 112 to the outside of the anti-shake fixing part 11 and further upwards.

[0088] Continue to refer to the appendix Figures 1 to 6 The anti-shake movable part 12 includes a movable carrier 121 and a set of balls 122, wherein the set of balls 122 is rotatably disposed between the movable carrier 121 and the upper cover 112 so that the anti-shake movable part 12 and the anti-shake fixed part 11 make point friction contact, thereby ensuring that the anti-shake driving part 13 smoothly drives the anti-shake movable part 12 to perform translational and / or rotational movements relative to the anti-shake fixed part 11.

[0089] Specifically, the movable carrier 121 has a carrier front side 1211, a carrier back side 1212 opposite to the carrier front side 1211, and a carrier opening 1213 extending from the carrier front side 1211 to the carrier back side 1212. The circuit board 31 of the photosensitive assembly 30 is disposed on the carrier back side 1212 of the movable carrier 121, and the photosensitive element 32 of the photosensitive assembly 30 corresponds to the carrier opening 1213 of the movable carrier 121, so that incident light is allowed to reach the photosensitive element 32 through the carrier opening 1213 of the movable carrier 121.

[0090] There is a gap between the circuit board 31 of the photosensitive component 30 and the base 111 of the anti-shake fixing part 11. A set of ball bearings 122 are rotatably disposed between the front surface 1211 of the movable carrier 121 and the inner wall of the upper cover 112, so that the anti-shake movable part 12 and the anti-shake fixing part 11 make point friction contact, so that the anti-shake driving part 13 smoothly drives the anti-shake movable part 12 to make translational and / or rotational movements relative to the anti-shake fixing part 11.

[0091] Optionally, in some specific examples of the camera module of the present invention, the photosensitive component 30 can be embedded in the carrier opening 1213 of the movable carrier 121 to facilitate a reduction in the height of the camera module. In other words, the movable carrier 121 is arranged around the photosensitive component 30. At this time, on the one hand, there is a gap between the carrier back surface 1212 of the movable carrier 121 and the base 111 of the image stabilization fixing part 11; on the other hand, a set of rolling balls 122 is provided between the carrier front surface 1211 of the movable carrier 121 and the inner wall of the upper cover 112 of the image stabilization fixing part 11, thereby suspending the image stabilization movable part 12 in the receiving cavity 1101 of the image stabilization fixing part 11, so as to ensure that the image stabilization driving part 13 can smoothly drive the image stabilization movable part 12 to perform translational and / or rotational movements relative to the image stabilization fixing part 11.

[0092] Optionally, in some specific examples of the camera module of the present invention, the circuit board 31 of the photosensitive component 30 is mounted on the front surface 1211 of the movable carrier 121. In this case, on the one hand, there is a gap between the back surface 1212 of the movable carrier 121 and the base 111 of the image stabilization fixing part 11; on the other hand, a set of rolling balls 122 is provided between the front surface 1211 of the movable carrier 121 and the inner wall of the upper cover 112 of the image stabilization fixing part 11, and the set of balls 122 ensures that there is a gap between the photosensitive component 30 and the upper cover 112, thereby suspending the image stabilization movable part 12 in the receiving cavity 1101 of the image stabilization fixing part 11, so as to ensure that the image stabilization driving part 13 can smoothly drive the image stabilization movable part 12 to perform translational and / or rotational movements relative to the image stabilization fixing part 11. It is understood that in these examples where the circuit board 31 of the photosensitive component 30 is mounted on the front side 1211 of the movable carrier 121, the movable carrier 121 may not need to have the carrier opening 1213.

[0093] Continue to refer to the appendix Figures 1 to 6The image stabilization drive unit 13 includes a plurality of image stabilization magnets 131 and a plurality of image stabilization coils 132. The image stabilization magnets 131 are respectively disposed on the image stabilization fixed part 11, and the image stabilization coils 132 are respectively disposed on the image stabilization movable part 12. The image stabilization magnets 131 and the image stabilization coils 132, when energized, interact with each other to drive the image stabilization movable part 12 to perform translational and / or rotational movements relative to the image stabilization fixed part 11, thereby achieving translational and / or rotational image stabilization of the camera module. For example, the image stabilization magnets 131 and the image stabilization coils 132 of the image stabilization drive unit 13 can interact to drive the image stabilization movable part 12 to perform translational movements along the X-axis and / or Y-axis directions relative to the image stabilization fixed part 11, thereby achieving translational image stabilization of the camera module. The anti-shake magnets 131 and the anti-shake coils 132 of the anti-shake drive unit 13 can interact to drive the anti-shake movable part 12 to rotate about the Z-axis relative to the anti-shake fixed part 11, thereby realizing the rotational anti-shake of the camera module.

[0094] Preferably, in the appendix Figures 1 to 6 In the camera module shown, the anti-shake magnets 131 of the anti-shake drive unit 13 are respectively disposed on the upper cover 112 of the anti-shake fixing unit 11. Correspondingly, the anti-shake coils 132 of the anti-shake drive unit 13 are respectively disposed on the anti-shake movable part 12, and each anti-shake magnet 131 corresponds to each anti-shake coil 132. For example, from the attached... Figure 1 From the direction shown, the anti-shake magnet 131 is located above the anti-shake coil 132, that is, the anti-shake magnet 131 and the anti-shake coil 132 are arranged vertically.

[0095] Furthermore, the drive assembly 10 includes at least one magnetically conductive member 14, which is disposed above the image stabilizing magnet 131. In this way, on the one hand, the magnetically conductive member 14 can strengthen the magnetic field intensity downward (i.e., in the direction where the image stabilizing coil 132 is located), so that the image stabilizing drive unit 13 has sufficient driving force to drive the image stabilizing movable part 12 to perform translational and / or rotational movements relative to the image stabilizing fixed part 11. On the other hand, the magnetically conductive member 14 can prevent magnetic leakage towards the lens carrier 21 and thus avoid interfering with the magnetic field of the lens carrier 21.

[0096] In other words, for the camera module that uses a magnet on the lens carrier 21 to achieve focusing, zooming and / or image stabilization, the magnetic field of the lens carrier 21 and the magnetic field of the image stabilization drive unit 13 can be isolated by covering the image stabilization magnet 131 on the image stabilization drive unit 13, thereby avoiding mutual interference between the two and ensuring the reliability and stability of the camera module.

[0097] Specifically, the magnetically conductive member 14 is disposed on the upper cover 112 of the image stabilization fixing part 11, and the image stabilization magnet 131 is disposed on the magnetically conductive member 14. That is, the image stabilization magnet 131 is disposed on the upper cover 112 by being disposed on the magnetically conductive member 14, thus keeping the magnetically conductive member 14 between the image stabilization magnet 131 and the upper cover 112. With this structural design, the magnetically conductive member 14 allows the magnetic lines of force of the image stabilization magnet 131 to concentrate towards the direction of the image stabilization coil 132, thereby increasing the magnetic field strength of the image stabilization drive part 13 and reducing the magnetic field strength overflowing to the lens carrier 21, thereby avoiding magnetic interference to the lens carrier 21.

[0098] More specifically, looking at the plane along one side of the optical axis of the camera module, the magnetically conductive member 14 has a quadrilateral structure. The area of ​​the magnetically conductive member 14 is greater than or equal to the area of ​​the image stabilizing magnet 131, and the magnetically conductive member 14 completely covers the image stabilizing magnet 131. Thus, the magnetically conductive member 14 effectively prevents the magnetic force of the image stabilizing magnet 131 from leaking out. In other words, the magnetically conductive member 14 covers the surface of the image stabilizing magnet 131 facing the optical lens 22. For example, in a specific example of the camera module of the present invention, the shape of the magnetically conductive member 14 is the same as the shape of the image stabilizing magnet 131; that is, the magnetically conductive member 14 is a square flat plate that is placed over the image stabilizing magnet 131, completely covering the upper surface of the image stabilizing magnet 131.

[0099] Preferably, in the appendix Figures 1 to 6 In this specific example of the camera module of the present invention shown, the shape of the magnetic conductive member 14 is different from the shape of the anti-shake magnet 131. For example, the magnetic conductive member 14 is a "U" shape with an opening, which can not only cover the upper surface of the anti-shake magnet 131, but also wrap at least a portion of the two opposite sides of the anti-shake magnet 131 so that the magnetic lines of force of the anti-shake magnet 131 are concentrated in the direction of the anti-shake coil 132.

[0100] It is worth mentioning that the correspondence between the number of the magnetically conductive components 14 and the number of the anti-shake magnets 131 is not limited in the camera module of the present invention. For example, in the attached... Figures 1 to 6In this specific example of the camera module of the present invention, the number of magnetically conductive members 14 is the same as the number of image-stabilizing magnets 131, so that one magnetically conductive member 14 can be placed over each image-stabilizing magnet 131, thus the magnetically conductive member 14 and the image-stabilizing magnet 131 can correspond one-to-one. Optionally, in other examples of the camera module of the present invention, the number of magnetically conductive members 14 is less than the number of image-stabilizing magnets 131, so that one magnetically conductive member 14 can be placed over at least two image-stabilizing magnets 131.

[0101] Those skilled in the art will understand that, with reference to the appendix Figure 5 and Figure 6 The photosensitive element 32 of the photosensitive assembly 30 is rectangular and has four sides. For ease of description and understanding, the four sides of the photosensitive element 32 are defined sequentially in a clockwise direction as a first chip side 321, a second chip side 322, a third chip side 323, and a fourth chip side 324. A coordinate system is established with the center point of the photosensitive element 32 as the origin, the direction parallel to the first chip side 321 and the third chip side 323 as the X-axis, the direction parallel to the second chip side 322 and the fourth chip side 324 as the Y-axis, and the direction perpendicular to the photosensitive surface of the photosensitive element 32 as the Z-axis.

[0102] Based on the arrangement of the stabilization coils 132 in the image stabilization drive unit 13, these stabilization coils 132 form a first coil group 133, a second coil group 134, and a third coil group 135. In the plane containing the X and Y axes, the first coil group 133 is arranged along the Y-axis, while the second coil group 134 and the third coil group 135 are arranged along the X-axis. The second coil group 134 and the third coil group 135 are located on opposite sides of the photosensitive element 32, thus surrounding the photosensitive element 32 of the photosensitive assembly 30. Preferably, the second coil group 134 and the third coil group 135 are symmetrical with respect to the Y-axis. It is understood that the second coil group 134 and the third coil group 135 are located on opposite sides of the top opening 1102 of the image stabilization fixing part 11.

[0103] The number of image stabilization coils 132 constituting the first coil group 133 is at least one, the number of image stabilization coils 132 constituting the second coil group 134 is at least two, and the number of image stabilization coils 132 constituting the third coil group 135 is at least two. Preferably, in the attached... Figures 1 to 6In this specific example of the camera module shown, the number of image stabilization coils 132 that make up the first coil group 133, the second coil group 134 and the third coil group 135 are all two.

[0104] Specifically, the two image stabilization coils 132 constituting the first coil group 133 are defined as a first coil 1321 and a second coil 1322, respectively, and the first coil 1321 and the second coil 1322 are arranged opposite to each other and parallel along the Y-axis direction; the two image stabilization coils 132 constituting the second coil group 134 are defined as a third coil 1323 and a fourth coil 1324, respectively, and the third coil 1323 and the fourth coil 1324 are arranged opposite to each other and parallel along the X-axis direction; the two image stabilization coils 132 constituting the third coil group 135 are defined as a fifth coil 1325 and a sixth coil 1326, respectively, and the fifth coil 1325 and the sixth coil 1326 are arranged opposite to each other and parallel.

[0105] In other words, the first coil 1321 and the second coil 1322 are respectively disposed on the fourth chip side 324 and the second chip side 322 of the photosensitive element 32, and the first coil 1321 and the second coil 1322 are respectively parallel to the fourth chip side 324 and the second chip side 322 of the photosensitive element 32. The third coil 1323 and the fifth coil 1325 are respectively disposed on the first chip side 321 of the photosensitive element 32, and the third coil 1323 and the fifth coil 1325 are respectively parallel to the first chip side 321 of the photosensitive element 32. The fourth coil 1324 and the sixth coil 1326 are respectively disposed on the third chip side 324 of the photosensitive element 32, and the fourth coil 1324 and the sixth coil 1326 are respectively parallel to the third chip side 323 of the photosensitive element 32.

[0106] In the appendix Figures 1 to 6In this specific example of the camera module of the present invention, the first coil 1321 and the second coil 1322, which constitute the first coil group 133, are respectively disposed on two opposite sides of the photosensitive element 32 along the Y-axis direction. The third coil 1323 and the fourth coil 1324, which constitute the second coil group 134, and the fifth coil 1325 and the sixth coil 1326, which constitute the third coil group 135, are respectively disposed at the four corners of the photosensitive element 32 along the X-axis direction. For example, the first coil 1321 is disposed adjacent to the third coil 1323 and the fourth coil 1324, and the first coil 1321 is perpendicular to the third coil 1323 and the fourth coil 1324, respectively. Correspondingly, the second coil 1322 is disposed adjacent to the fifth coil 1325 and the sixth coil 1326, and the second coil 1322 is perpendicular to the fifth coil 1325 and the sixth coil 1326, respectively. In other words, the distance between the second coil group 134 and the third coil group 135 and the center of the photosensitive element 32 is greater than the distance between the first coil group 133 and the center of the photosensitive element 32, and the torque is greater. Thus, the second coil group 134 and the third coil group 135 cooperate more easily to drive the stabilization movable part 12 to rotate relative to the stabilization fixed part 11, so as to achieve rotational stabilization.

[0107] Specifically, the first coil 1321 and the second coil 1322 constituting the first coil group 133 are of the same size; the third coil 1323 and the fourth coil 1324 constituting the second coil group 134, and the fifth coil 1325 and the sixth coil 1326 constituting the third coil group 135 are of the same size; and the size of the first coil 1321 and the second coil 1322 is larger than that of the third coil 1323, the fourth coil 1324, the fifth coil 1325, and the sixth coil 1326. The size of the coil is 26, wherein the first coil 1321 and the second coil 1322 cooperate to drive the movable anti-shake part 12 to translate relative to the fixed anti-shake part 11 along the X-axis direction, and the third coil 1323, the fourth coil 1324, the fifth coil 1325 and the sixth coil 1326 cooperate to drive the movable anti-shake part 12 to translate relative to the fixed anti-shake part 11 along the Y-axis direction and / or drive the movable anti-shake part 12 to rotate relative to the fixed anti-shake part 11 around the Z-axis direction. It is understood that the first coil 1321 and the second coil 1322 have a large size to ensure that they have a large thrust to drive the movable anti-shake part 12 to translate relative to the fixed anti-shake part 11 along the X-axis direction.

[0108] Optionally, in other examples of the camera module of the present invention, the first coil 1321 and the second coil 1322 constituting the first coil group 133, the third coil 1323 and the fourth coil 1324 constituting the second coil group 134, and the fifth coil 1325 and the sixth coil 1326 constituting the third coil group 135 may have the same size.

[0109] Preferably, the geometric centers of the first coil 1321 and the second coil 1322 constituting the first coil group 133 are aligned with the center of the image stabilization drive unit 13. That is, the distance between the center of the first coil 1321 and the center of the photosensitive element 32 (the origin of the coordinate axis) is the same as the distance between the center of the second coil 1322 and the center of the photosensitive element 32. This ensures that the resultant force generated by the first coil 1321 and the second coil 1322 remains at the center of the image stabilization drive unit 13, thereby avoiding unnecessary torque generated by the first coil 1321 and the second coil 1322.

[0110] For example, in a specific example of the camera module of the present invention, when viewed along one side of the optical axis of the camera module, the center of the first coil 1321 and the center of the second coil 1322 are aligned, such that the line connecting the center of the first coil 1321 and the center of the second coil 1322 passes through the center of the photosensitive element 32 and is parallel to the X-axis direction.

[0111] In another specific example of the camera module of the present invention, looking at its plane along one side of the optical axis of the camera module, the center of the first coil 1321 and the center of the second coil 1322 are somewhat off-center. The off-center direction of the center of the first coil 1321 and the center of the second coil 1322 can be either the positive direction of the Y-axis or the negative direction of the Y-axis. The line connecting the center of the first coil 1321 and the center of the second coil 1322 passes through the center of the photosensitive element 32 and intersects the X-axis direction. That is, in this embodiment of the camera module of the present invention, the center of the first coil 1321 can be off-center in the positive direction of the Y-axis, and correspondingly, the center of the second coil 1322 can be off-center in the negative direction of the Y-axis. The distance from the center of the first coil 1321 to the X-axis is the same as the distance from the center of the second coil 1322 to the X-axis, thus ensuring that the resultant force generated by the first coil 1321 and the second coil 1322 is located at the center of the image stabilization drive unit 13. Alternatively, the center of the first coil 1321 can be biased towards the negative direction of the Y-axis, and correspondingly, the center of the second coil 1322 can be biased towards the positive direction of the Y-axis. Furthermore, the distance from the center of the first coil 1321 to the X-axis is the same as the distance from the center of the second coil 1322 to the X-axis. This ensures that the resultant force generated by the first coil 1321 and the second coil 1322 is located at the center of the anti-shake drive unit 13.

[0112] Furthermore, the anti-shake coils 132 of the anti-shake drive unit 13 are all hollow planar coils, forming a coil plane 13201 and a coil space 13202. Preferably, the coil planes 13201 of the first coil 1321, the second coil 1322, the third coil 1323, the fourth coil 1324, the fifth coil 1325, and the sixth coil 1326 are flush, so that the anti-shake drive unit 13 can drive the anti-shake movable part 12 to translate within the plane XOY formed by the X-axis and Y-axis.

[0113] Furthermore, the movable carrier 121 has a plurality of mounting positions 1210, the number of mounting positions 1210 being the same as the number of the image stabilization coils 132, and each mounting position 1210 being used to mount each of the image stabilization coils 132.

[0114] Based on the placement positions 1210, these placement positions 1210 form a first position group 12101, a second position group 12102, and a third position group 12103, wherein each placement position 1210 constituting the first position group 12101 is respectively disposed on two opposite sides along the Y-axis direction, and each placement position 1210 constituting the second position group 12102 and the third position group 12103 is respectively disposed at four corners along the X-axis direction.

[0115] Further, each of the placement positions 1210 constituting the first position group 12101 is arranged along the Y-axis direction, each of the placement positions 1210 constituting the second position group 12102 is arranged along the X-axis direction, and each of the placement positions 1210 constituting the third position group 12103 is arranged along the X-axis direction. Furthermore, each of the placement positions 1210 constituting the second position group 12102 is arranged opposite to each other along the Y-axis direction, and each of the placement positions 1210 constituting the third position group 12103 is arranged opposite to each other along the Y-axis direction. Preferably, each of the placement positions 1210 constituting the second position group 12102 is symmetrical with respect to the Y-axis, and each of the placement positions 1210 constituting the third position group 12103 is symmetrical with respect to the Y-axis.

[0116] The shape of the mounting position 1210 is the same as that of the image stabilization coil 132, so as to facilitate the mounting of the image stabilization coil 132 on the mounting position 1210. Viewed from the optical axis side of the camera module, the mounting position 1210 is rectangular or approximately rectangular in structure. The long side of each mounting position 1210 forming the first position group 12101 is parallel to the Y-axis direction, while the long sides of each mounting position 1210 forming the second position group 12102 and the third position group 12103 are parallel to the X-axis direction. Furthermore, the long side of each mounting position 1210 forming the first position group 12101 is perpendicular to the long side of each mounting position 1210 forming the second position group 12102 and the third position group 12103, respectively.

[0117] In some examples of the camera module of the present invention, the mounting position 1210 may be a planar mounting position, such that the image stabilization coil 132 can be directly disposed on the surface of the mounting position 1210. In other examples of the camera module of the present invention, the mounting position 1210 may be a recessed mounting position, such that the image stabilization coil 132 can be embedded in the mounting position 1210 to reduce the height of the drive assembly 10. In still other examples of the camera module of the present invention, the mounting position 1210 may be a through-hole mounting position, such that the image stabilization coil 132 can be embedded in the mounting position 1210 to reduce the height of the drive assembly 10.

[0118] Based on the arrangement of the anti-shake magnets 131 in the anti-shake drive unit 13, these anti-shake magnets 131 form a first magnet group 136, a second magnet group 137, and a third magnet group 138. In the plane containing the X and Y axes, the first magnet group 136 is arranged along the Y-axis, while the second magnet group 137 and the third magnet group 138 are arranged along the X-axis. The second magnet group 137 and the third magnet group 138 are located on opposite sides of the photosensitive element 32, thus surrounding the photosensitive element 32 of the photosensitive assembly 30. Preferably, the second magnet group 137 and the third magnet group 138 are symmetrical with respect to the Y-axis.

[0119] The number of anti-shake magnets 131 constituting the first magnet group 136 is at least one, the number of anti-shake magnets 131 constituting the second magnet group 137 is at least two, and the number of anti-shake magnets 131 constituting the third magnet group 138 is at least two. Preferably, in the attached... Figures 1 to 6 In this specific example of the camera module shown, the number of anti-shake magnets 131 that make up the first magnet group 136, the second magnet group 137, and the third magnet group 138 are all two.

[0120] Specifically, the two anti-shake magnets 131 constituting the first magnet group 136 are defined as a first magnet 1311 and a second magnet 1312, respectively. The first magnet 1311 and the second magnet 1312 are arranged opposite to each other and parallel along the Y-axis direction, and the first magnet 1311 is arranged opposite to the first coil 1321, while the second magnet 1312 is arranged opposite to the second coil 1322. The two anti-shake magnets 131 constituting the second magnet group 137 are defined as a third magnet 1313 and a fourth magnet 1314, respectively. The third magnet 1313 and the fourth magnet 1314 are arranged opposite to each other and parallel along the X-axis direction, and the third magnet 1313 is arranged opposite to the third coil 1323, while the fourth magnet 1314 is arranged opposite to the fourth coil 1324. The two anti-shake magnets 131 that make up the third magnet group 138 are defined as a fifth magnet 1315 and a sixth magnet 1316, respectively. The fifth magnet 1315 and the sixth magnet 1316 are arranged opposite to each other and parallel to each other along the X-axis direction. The fifth magnet 1315 is arranged opposite to the fifth coil 1325, and the sixth magnet 1316 is arranged opposite to the sixth coil 1326.

[0121] In other words, the first magnet 1311 and the second magnet 1312 are respectively disposed on the fourth chip side 324 and the second chip side 322 of the photosensitive element 32, and the first magnet 1311 and the second magnet 1312 are respectively parallel to the fourth chip side 324 and the second chip side 322 of the photosensitive element 32. The third magnet 1313 and the fifth magnet 1315 are respectively disposed on the first chip side 321 of the photosensitive element 32, and the third magnet 1313 and the fifth magnet 1315 are respectively parallel to the first chip side 321 of the photosensitive element 32. The fourth magnet 1314 and the sixth magnet 1316 are respectively disposed on the third chip side 323 of the photosensitive element 32, and the fourth magnet 1314 and the sixth magnet 1316 are respectively parallel to the third chip side 323 of the photosensitive element 32.

[0122] In the appendix Figures 1 to 6In this specific example of the camera module of the present invention shown, the first magnet 1311 and the second magnet 1312 constituting the first magnet group 136 are respectively disposed on two opposite sides of the photosensitive element 32 along the Y-axis direction, and the third magnet 1313 and the fourth magnet 1314 constituting the second magnet group 137 and the fifth magnet 1315 and the sixth magnet 1316 constituting the third magnet group 138 are respectively disposed at the four corners of the photosensitive element 32 along the X-axis direction. For example, the first magnet 1311 is arranged adjacent to the third magnet 1313 and the fourth magnet 1314 respectively, and the first magnet 1311 is perpendicular to the third magnet 1313 and the fourth magnet 1314 respectively. Correspondingly, the second magnet 1312 is arranged adjacent to the fifth magnet 1315 and the sixth magnet 1316 respectively, and the second magnet 1312 is perpendicular to the fifth magnet 1315 and the sixth magnet 1316 respectively.

[0123] Specifically, the first magnet 1311 and the second magnet 1312 constituting the first magnet group 136 are of the same size; the third magnet 1313 and the fourth magnet 1314 constituting the second magnet group 137 and the fifth magnet 1315 and the sixth magnet 1316 constituting the third magnet group 138 are of the same size; and the size of the first magnet 1311 and the second magnet 1312 is larger than that of the third magnet 1313, the fourth magnet 1314, the fifth magnet 1315, and the sixth magnet 1316. The image is sized 16, wherein the first magnet 1311 and the second magnet 1312 cooperate to drive the anti-shake drive unit 13 to translate relative to the anti-shake fixed unit 11 along the X-axis direction, and the third magnet 1313, the fourth magnet 1314, the fifth magnet 1315, and the sixth magnet 1316 cooperate to drive the anti-shake drive unit 13 to translate relative to the anti-shake fixed unit 11 along the Y-axis direction or to drive the anti-shake drive unit 13 to rotate relative to the anti-shake fixed unit 11 around the Z-axis direction. It is understood that the first magnet 1311 and the second magnet 1312 have large dimensions to ensure that they have a large thrust to drive the anti-shake movable unit 12 to translate relative to the anti-shake fixed unit 11 along the X-axis direction.

[0124] Optionally, in other examples of the camera module of the present invention, the first magnet 1311 and the second magnet 1312 constituting the first magnet group 136, the third magnet 1313 and the fourth magnet 1314 constituting the second magnet group 137, and the fifth magnet 1315 and the sixth magnet 1316 constituting the third magnet group 138 may have the same size.

[0125] In one specific example of the camera module of the present invention, the stabilizing magnet 131 of the stabilization drive unit 13 is a unipolar magnet having one N pole and one S pole, the N pole and S pole being arranged horizontally and facing the stabilization coil 132. Optionally, in some other examples of the camera module of the present invention, the stabilizing magnet 131 of the stabilization drive unit 13 is a bipolar magnet having two N poles and two S poles. The N poles and S poles in the first set of magnetic poles are arranged horizontally and facing the stabilization coil 132. The S pole in the second set of magnetic poles is located at the bottom of the N pole in the first set of magnetic poles, and the N pole in the second set of magnetic poles is located at the bottom of the S pole in the first set of magnetic poles. Thus, the S poles and N poles in the second set of magnetic poles are arranged horizontally and away from the stabilization coil 132.

[0126] It should be noted that, in this specific example of the camera module of the present invention, the first coil 1321 and the second coil 1322 constituting the first coil group 133 correspond to the first magnet 1311 and the second magnet 1312 constituting the first magnet group 136, respectively. Thus, when the first coil 1321 and the second coil 1322 are energized, the magnetic field generated by the first coil 1321 and the magnetic field of the first magnet 1311 cooperate with each other, and the magnetic field generated by the second coil 1322 and the magnetic field of the second magnet 1312 cooperate with each other to drive the image stabilization movable part 12 to translate in the X-axis direction, so as to realize translational image stabilization along the X-axis direction. The third coil 1323 and the fourth coil 1324 constituting the second coil group 134 correspond to the third magnet 1313 and the fourth magnet 1314 constituting the second magnet group 137, respectively. The fifth coil 1325 and the sixth coil 1326 constituting the third coil group 135 correspond to the fifth magnet 1315 and the sixth magnet 1316 constituting the third magnet group 138, respectively. Thus, when the second coil group 134 and the third coil group 135 are supplied with currents of the same direction and magnitude, the second coil group 134 and... The second magnet group 137 cooperates with the third coil group 135 and the third magnet group 138 to drive the anti-shake movable part 12 to translate in the Y-axis direction, thereby achieving translational anti-shake in the Y-axis direction. When the second coil group 134 and the third coil group 135 are energized with currents of opposite directions but the same value, the second coil group 134 and the second magnet group 137 cooperate with the third coil group 135 and the third magnet group 138 to drive the anti-shake movable part 12 to rotate around the Z-axis, thereby achieving rotational anti-shake in the Z-axis direction.

[0127] Preferably, the anti-shake drive unit 13 has a translational stroke of ±235μm in the X and Y axis directions and a rotational stroke of ±1° around the Z axis.

[0128] Continue to refer to the appendix Figures 1 to 6 The image stabilization movable part 12 further includes an electrical connection part 123, wherein the image stabilization coils 132 of the image stabilization drive part 13 are respectively connected to the electrical connection part 123 to supply power to the image stabilization coils 132 through the electrical connection part 123. Preferably, the electrical connection part 123 is electrically connected to the circuit board 31 of the photosensitive component 30.

[0129] Preferably, the electrical connection portion 123 is a frame-shaped structure forming a connection opening 1231, wherein the electrical connection portion 123 is attached to the carrier back surface 1212 of the movable carrier 121, and the connection opening 1231 of the electrical connection portion 123 and the carrier opening 1213 of the movable carrier 121 correspond to and communicate with each other, wherein the circuit board 31 of the photosensitive component 30 is fixed to the electrical connection portion 123, such that incident light is allowed to reach the photosensitive element 32 through the carrier opening 1213 of the movable carrier 121 and the connection opening 1231 of the electrical connection portion 123.

[0130] Optionally, in some other examples of the camera module of the present invention, the movable image stabilization part 12 may not have the electrical connection part 123. In this case, the image stabilization coils 132 of the image stabilization drive part 13 are respectively mounted on the circuit board 31 of the photosensitive component 30 so as to supply power to the image stabilization coils 132 through the circuit board 31. In this case, the circuit board 31 of the photosensitive component 30 can be directly mounted on the back surface 1212 of the movable carrier 121.

[0131] Continue to refer to the appendix Figures 1 to 6 The movable carrier 121 has multiple carrier notches 1214 extending from the front side 1211 to the back side 1212. The anti-shake coils 132 of the anti-shake drive unit 13 are held in these carrier notches 1214. Thus, with the electrical connection 123 attached to the back side 1212 of the movable carrier 121, the anti-shake coils 132 of the anti-shake drive unit 13 can extend towards the anti-shake magnet 131 via the multiple carrier notches 1214 of the movable carrier 121. In other words, these carrier notches 1214 of the movable carrier 121 can form mounting positions 1210 for mounting the anti-shake coils 132.

[0132] It is worth mentioning that the shape of the carrier notch 1214 of the movable carrier 121 is not limited in the camera module of the present invention.

[0133] Preferably, in this embodiment of the camera module of the present invention, the image stabilization coils 132 of the image stabilization drive unit 13 are respectively attached to the electrical connection part 123. By attaching the electrical connection part 123 to the back surface 1212 of the movable carrier 121, the image stabilization coils 132 can be respectively held in the carrier notches 1214 of the movable carrier 121.

[0134] Optionally, in other examples of the camera module of the present invention, the image stabilization coils 132 of the image stabilization drive unit 13 are respectively fixed to the movable carrier 121, and the image stabilization coils 132 can be connected to the electrical connection unit 123 or to the circuit board 31 via connecting wires. In this case, the movable carrier 121 may not have the carrier notch 1214 provided.

[0135] Continue to refer to the appendix Figures 1 to 6 The drive assembly 10 further includes at least one magnetic member 15, wherein the magnetic member 15 is disposed on the anti-shake movable part 12, and the position of the magnetic member 15 corresponds to the position of the anti-shake magnet 131 of the anti-shake drive part 13, so that the magnetic member 15 and the anti-shake magnet 131 can cooperate with each other to generate a magnetic attraction force in the Z-axis direction to suspend the anti-shake movable part 12 in the receiving cavity 1101 of the anti-shake fixing part 11.

[0136] In other words, the magnetic attraction force generated by the magnetic attraction component 15 and the anti-shake magnet 131 of the anti-shake drive part 13 in the Z-axis direction can ensure that a set of the ball bearings 122 of the movable anti-shake part 12 are always in close contact with the upper cover 112 of the fixed anti-shake part 11. Since a set of rolling ball bearings 122 is provided between the front surface 1211 of the movable carrier 121 and the inner wall of the upper cover 112, the movable anti-shake part 12 and the fixed anti-shake part 11 are in point friction contact. In this way, the anti-shake drive part 13 can smoothly drive the movable anti-shake part 12 to make translational and / or rotational movements relative to the fixed anti-shake part 11, so as to realize the translational anti-shake and / or rotational anti-shake of the camera module.

[0137] Preferably, the movable carrier 121 has a set of retaining grooves 1215 formed on the carrier front 1211 of the movable carrier 121, wherein the ball bearing 122 is rotatably held in the retaining grooves 1215 of the movable carrier 121. In this way, when the anti-shake driving unit 13 drives the anti-shake movable part 12 to perform translational and / or rotational movements relative to the anti-shake fixing part 11, the ball bearing 122 can be prevented from disengaging from the movable carrier 121 and the upper cover 112, thereby ensuring the reliability and stability of the camera module. Specifically, when the driving unit 13 drives the movable carrier 121 of the anti-shake movable part 12 to perform translational and / or rotational movements relative to the anti-shake fixing part 11, the movement trajectory of the ball bearing 122 can be restricted within the retaining grooves 1215 of the movable carrier 121, so that the ball bearing 122 always supports the movable carrier 121 and the upper cover 112 of the anti-shake fixing part 11.

[0138] In other words, the retaining groove 1215 and the ball bearings 122 of the movable carrier 121 can form a support portion 17 of the drive assembly 10. That is, the support portion 17 includes a set of ball bearings 122 and a set of retaining grooves 1215, wherein the set of retaining grooves 1215 are respectively formed on the carrier front surface 122 of the movable carrier 121, and the set of ball bearings 122 are respectively rollably held in the retaining grooves 1215 and located between the movable carrier 121 and the upper cover 112. Thus, the support portion 17 can support the movable carrier 121 and the upper cover 112. The ball bearings 122 can move along the plane formed by the X-axis and Y-axis within the retaining grooves 1215 to provide movement space for the movement of the anti-shake movable portion 12.

[0139] Furthermore, the movable carrier 121 has at least one extension post 1216, and the retaining groove 1215 is formed in the extension post 1216, with the opening of the retaining groove 1215 facing the upper cover 112 of the anti-shake fixing part 11. The depth of the retaining groove 1215 is less than or equal to the diameter of the ball 122, such that at least a portion of the ball 122 can protrude from the retaining groove 1215, and the height of the ball 122 is greater than the height of the anti-shake coil 132, so that the ball 122 can make point frictional contact with the extension post 1216 of the movable carrier 121 and the upper cover 112, respectively.

[0140] Understandably, with the above structural design, the upper part of the ball bearing 122 faces the plane formed by the inner wall of the upper cover 112, and the lower part of the ball bearing 122 faces the groove formed by the retaining groove 1215. Thus, on the one hand, the ball bearing 122 can roll between the movable carrier 121 and the upper cover 112; on the other hand, the retaining groove 1215 can limit the ball bearing 122 to prevent it from falling off, thereby ensuring the reliability of the camera module.

[0141] It is understood that the ball bearing 122 creates a gap between the anti-shake magnet 131 and the anti-shake coil 132 to avoid direct contact between them. Preferably, the gap between the anti-shake magnet 131 and the anti-shake coil 132 is between 0.05 mm and 0.5 mm to ensure good electromagnetic induction between them.

[0142] Furthermore, the drive assembly 10 includes at least three of the support portions 17 to ensure smooth translation of the anti-shake movable portion 12 along the X-axis and Y-axis and rotation about the Z-axis. That is, the anti-shake movable portion 12 includes at least three of the ball bearings 122, and the movable carrier 121 has at least three of the retaining grooves 1215.

[0143] Preferably, in the appendix Figures 1 to 6 In this specific example of the camera module shown, the drive assembly 10 includes four support portions 17, which are respectively disposed between the first position group 12101 and the second position group 12102, and between the second position group 12102 and the third position group 12103. That is, the four support portions 17 of the drive assembly 10 are respectively located at the four corners of the image stabilization movable part 12, providing more stable support for the image stabilization movable part 12, while making full use of the internal space of the drive assembly 10 to make its structure more compact. Optionally, in other examples of the camera module of the present invention, the support portions 17 of the drive assembly 10 may be sliders, which are slidably held between the movable carrier 121 and the upper cover 112 for stable support of the image stabilization movable part 12. (Continue referring to the appendix...) Figures 1 to 6 The driving assembly 10 includes four magnetic suction members 15, each of which is disposed at each corner of the anti-shake movable part 12. This ensures the flatness of the anti-shake movable part 12 and allows the optical axis of the camera module to be perpendicular to the photosensitive surface of the photosensitive element 32 of the photosensitive assembly 30.

[0144] Continue to refer to the appendix Figures 1 to 6 In this specific example of the camera module of the present invention, the magnetic suction member 15 is disposed on the electrical connection portion 123 to optimize the structure of the camera module. Optionally, in other examples of the camera module of the present invention, the magnetic suction member 15 may be disposed on the movable carrier 121, or the magnetic suction member 15 may be disposed on the circuit board 31 of the photosensitive component 30, or the magnetic suction member 15 may be disposed between the movable carrier 121 and the electrical connection portion 123, or the magnetic suction member 15 may be disposed between the electrical connection portion 123 and the circuit board 31.

[0145] In some examples of the camera module of the present invention, the magnetic suction member 15 and the anti-shake magnet 131 of the anti-shake drive unit 13 can be perfectly aligned, that is, the magnetic suction member 15 can be located directly below the anti-shake magnet 131 of the anti-shake drive unit 13. In other examples of the camera module of the present invention, the magnetic suction member 15 and the anti-shake magnet 131 of the anti-shake drive unit 13 may not be perfectly aligned, and there may be some deviation between them.

[0146] It is understood that when the anti-shake driving unit 13 drives the anti-shake movable unit 12 to perform translational and / or rotational movements relative to the anti-shake fixed unit 11, the magnetic attraction member 15 will synchronously generate translational and / or rotational movements relative to the anti-shake fixed unit 11. At this time, some deviation will also occur between the magnetic attraction member 15 and the anti-shake magnet 131. However, the plane where the magnetic attraction member 15 is located and the plane where the anti-shake magnet 131 is located are always parallel, that is, the plane where the magnetic attraction member 15 is located and the plane where the anti-shake magnet 131 is located are always orthogonal to the Z-axis. Therefore, the magnetic attraction member 15 and the anti-shake magnet 131 can cooperate with each other to generate magnetic attraction in the Z-axis direction, which refers to the magnetic attraction between the plane where the magnetic attraction member 15 is located and the plane where the anti-shake magnet 131 is located, including but not limited to the magnetic attraction in the vertical direction and the tilting magnetic attraction that deviates from the vertical direction.

[0147] Continue to refer to the appendix Figures 1 to 6 The drive assembly 10 further includes at least three anti-shake position sensing elements 16, which respectively sense the position information of the anti-shake movable part 12 in the X-axis direction translation, Y-axis direction translation, and Z-axis direction rotation by sensing the position information of the first magnet group 136, the second magnet group 137, and the third magnet group 138.

[0148] Preferably, the three image stabilization position sensing elements 16 are defined as a first sensing element 161, a second sensing element 162, and a third sensing element 163, respectively. The first sensing element 161 is disposed in the coil space 13202 of the first coil 1321, corresponding to the first magnet 1311, wherein the first sensing element 161 is used to sense changes in the magnetic field during translation in the X-axis direction. The second sensing element 162 is disposed in the coil space 13202 of the fourth coil 1324, corresponding to the fourth magnet 1314, wherein the second sensing element 162 is used to sense changes in the magnetic field during translation in the Y-axis direction. The third sensing element 163 is disposed in the coil space 13202 of the fifth coil 1325, corresponding to the fifth magnet 1315, wherein the second sensing element 162 and the third sensing element 163 are used to sense changes in the magnetic field during rotation in the Z-axis direction.

[0149] Preferably, the anti-shake position sensing element 16 is attached to the electrical connection portion 123.

[0150] In the camera module of the present invention, the first coil group 133, the second coil group 134 and the third coil group 135 of the image stabilization drive unit 13 are independently controlled coil groups. Therefore, only three image stabilization position sensing elements 16 need to be set. This not only reduces the number of components in the drive assembly 10, but also helps to reduce the size of the drive assembly 10 by using fewer interfaces to realize translational image stabilization and / or rotational image stabilization sensing. Furthermore, it makes full use of the internal space of the drive assembly 10, making the structure of the drive assembly 10 compact.

[0151] It is worth mentioning that, in some embodiments of the camera module of the present invention, the image stabilization position sensing element 16 may be a Hall element. In other embodiments of the camera module of the present invention, the image stabilization position sensing element 16 may be a driver IC adapted to control the current of the image stabilization coil 132 while acquiring the position change of the image stabilization magnet 131. Specifically, when the camera module activates the image stabilization function, the image stabilization position sensing element 16 can sense the current positions of the first magnet group 136, the second magnet group 137, and the third magnet group 138, and drive the image stabilization movable part 12 to move to the sensed center position by controlling the current of the first coil group 133, the second coil group 134, and the third coil group 135. When the camera module deactivates the image stabilization function, the image stabilization movable part 12 returns to its initial position through the counterforce of the circuit board 31 of the photosensitive component 30 (i.e., the elastic force accumulated by the circuit board 31 due to elastic deformation when the image stabilization movable part 12 is translated and / or rotated).

[0152] Appendix Figure 7 A modified example of the camera module of the present invention is shown, with reference to the appendix. Figures 1 to 6 Unlike the camera module shown, the attached... Figure 7 In this modified example of the camera module shown, the first coil group 133 includes four image stabilization coils 132, wherein two of the image stabilization coils 132 constituting the first coil group 133 are symmetrically arranged at one end of the second chip side 322 and the fourth chip side 324 of the photosensitive element 32, and the other two image stabilization coils 132 are symmetrically arranged at the other end of the second chip side 322 and the fourth chip side 324 of the photosensitive element 32. The four retaining grooves 1215 of the movable carrier 121 are respectively formed in the middle of the first chip side 321, the second chip side 322, the third chip side 323 and the fourth chip side 324 of the photosensitive element 32, so that the four balls 122 are rotatably held between the carrier front 1211 and the inner wall of the upper cover 112 of the movable carrier 121 in the middle of the first chip side 321, the second chip side 322, the third chip side 323 and the fourth chip side 324 of the photosensitive element 32.

[0153] Appendix Figures 8A to 9B Another embodiment of the camera module of the present invention is shown, which, together with the attached... Figures 1 to 6 The difference in the camera module shown lies in the specific structure of the driving component 10. Specifically, in the attached... Figures 8A to 9B In this specific example of the camera module shown, the anti-shake magnets 131 of the anti-shake drive unit 13 are respectively disposed on the anti-shake movable part 12, and the anti-shake coils 132 are respectively disposed on the anti-shake fixed part 11. The anti-shake magnets 131 and the anti-shake coils 132 correspond to each other. The magnetic field generated by the energized anti-shake coils 132 and the magnetic field of the anti-shake magnets 131 can interact to drive the anti-shake movable part 12 to perform translational and / or rotational movements relative to the anti-shake fixed part 11, thereby achieving translational and / or rotational anti-shake of the camera module. For example, the anti-shake magnets 131 and the anti-shake coils 132 of the anti-shake drive unit 13 can interact to drive the anti-shake movable part 12 to perform translational movements along the X-axis and / or Y-axis directions relative to the anti-shake fixed part 11, thereby achieving translational anti-shake of the camera module. The anti-shake magnets 131 and the anti-shake coils 132 of the anti-shake drive unit 13 can interact to drive the anti-shake movable part 12 to rotate about the Z-axis relative to the anti-shake fixed part 11, thereby realizing the rotational anti-shake of the camera module.

[0154] Preferably, in the appendix Figures 8A to 9B In the camera module shown, the anti-shake magnets 131 of the anti-shake drive unit 13 are respectively disposed on the movable carrier 121 of the anti-shake movable unit 12. Correspondingly, the anti-shake coils 132 of the anti-shake drive unit 13 are respectively disposed on the upper cover 112 of the anti-shake fixing unit 11, and each anti-shake magnet 131 and each anti-shake coil 132 correspond one-to-one.

[0155] Preferably, the anti-shake magnets 131 of the anti-shake drive unit 13 are respectively installed in the mounting positions 1210 of the movable carrier 121.

[0156] Continue to refer to the appendix Figures 8A to 9B The electrical connection portion 123 is attached to the inner wall of the upper cover 112, and the connection opening 1231 of the electrical connection portion 123 corresponds to and communicates with the top opening 1102 of the anti-shake fixing portion 11, so as to prevent the electrical connection portion 123 from blocking the light entering the interior of the drive assembly 10 through the top opening 1102 of the anti-shake fixing portion 11. The anti-shake coils 132 of the anti-shake drive portion 13 can be respectively attached to the electrical connection portion 123 to set the anti-shake coils 132 to the upper cover 112 through the electrical connection portion 123.

[0157] In addition, the electrical connection portion 123 may have a plurality of clearance positions 1232, the size of which is larger than the size of the extension post 1216 of the movable carrier 121, so as to ensure that the anti-shake movable portion 12 can be driven to translate along the X-axis and / or Y-axis and / or rotate around the Z-axis.

[0158] Alternatively, in other examples of the camera module of the present invention, the camera module may not have the electrical connection part 123 provided, but instead the image stabilization coils 132 of the image stabilization drive part 13 are directly provided on the upper cover 112, and the image stabilization coils 132 are connected to the circuit board 31 of the photosensitive component 30 through connecting wires.

[0159] Continue to refer to the appendix Figures 8A to 9B The magnetic suction members 15 of the drive assembly 10 are respectively disposed on the upper cover 112 of the anti-shake fixing part 11, and the position of the magnetic suction members 15 corresponds to the position of the anti-shake magnet 131 of the anti-shake drive part 13. In this way, the magnetic suction members 15 and the anti-shake magnet 131 can cooperate with each other to generate magnetic attraction in the Z-axis direction to suspend the anti-shake movable part 12 in the receiving cavity 1101 of the anti-shake fixing part 11.

[0160] Alternatively, in other examples of the camera module of the present invention, the magnetic members 15 of the driving assembly 10 may be disposed on the electrical connection portion 123, or the magnetic members 15 may be disposed between the electrical connection portion 123 and the upper cover 112.

[0161] In the appendix Figure 10 In this modified example of the camera module shown, the magnetically conductive member 14 of the drive assembly 10 is located below the anti-shake magnet 131, such that: on the one hand, the magnetically conductive member 14 can strengthen the magnetic field upward (i.e., in the direction of the anti-shake coil 132) so that the anti-shake drive unit 13 has sufficient driving force to drive the anti-shake movable part 12 to perform translational and / or rotational movements relative to the anti-shake fixed part 11; on the other hand, the magnetically conductive member 14 can prevent the magnetic field of the anti-shake magnet 131 from leaking out, thereby avoiding interference with the circuit board 31 and the photosensitive element 32 of the photosensitive assembly 30.

[0162] Specifically, the magnetically conductive component 14 is disposed on the movable carrier 121, and the anti-shake magnet 131 is disposed on the magnetically conductive component 14, that is, the anti-shake magnet 131 is disposed on the movable carrier 121 by being disposed on the magnetically conductive component 14.

[0163] It is worth noting that the manner in which the magnetically conductive member 14 is disposed on the movable carrier 121 is not limited in the camera module of the present invention. For example, in some embodiments of the camera module of the present invention, after the magnetically conductive member 14 and the movable carrier 121 are respectively molded, the magnetically conductive member 14 can be disposed on the movable carrier 121 by means of adhesive bonding. In other embodiments of the camera module of the present invention, when the movable carrier 121 is injection molded, the movable carrier 121 can be integrally molded on the magnetically conductive member 14, thus disposing the magnetically conductive member 14 on the movable carrier 121.

[0164] With appendix Figures 1 to 6 Unlike the camera module shown, the attached... Figure 11 In this modified example of the camera module shown, the drive assembly 10 may not have the magnetic suction member 15, and the ball bearing 122 may not be provided between the movable carrier 121 and the upper cover 112. Specifically, the drive assembly 10 further includes a suspension portion 18 for suspending the image stabilization movable portion 12 in the receiving cavity 1101 of the image stabilization fixing portion 11.

[0165] Specifically, the suspension part 18 includes at least three elastic suspension elements 181, the top end of each suspension element 181 is connected to the upper cover 112 of the anti-shake fixing part 11, and the bottom end of each suspension element 181 is connected to the movable carrier 121 of the anti-shake movable part 12, so that the anti-shake movable part 12 is suspended in the receiving cavity 1101 of the anti-shake fixing part 11 by these suspension elements 181.

[0166] When the anti-shake coil 132 of the anti-shake drive unit 13 is energized, allowing the anti-shake coil 132 and the anti-shake magnet 131 to cooperate in driving the anti-shake movable part 12 to perform translational and / or rotational movements relative to the anti-shake fixed part 11, the anti-shake fixed part 11 drives the suspension elements 181, causing the suspension elements 181 to deform. Correspondingly, when the anti-shake coil 132 of the anti-shake drive unit 13 is de-energized, the suspension elements 181 can drive the anti-shake movable part 12 to return to its initial position during the process of restoring its initial state.

[0167] Preferably, the suspension portion 18 includes four suspension elements 181, the top ends of which are respectively connected to the four corners of the upper cover 112, and the bottom ends of which are respectively connected to the four corners of the movable carrier 121. Thus, the four suspension elements 181 of the suspension portion 18 can cooperate with each other to ensure that the anti-shake movable portion 12 moves smoothly and / or rotates within the receiving cavity 1101 of the anti-shake fixing portion 11. In this case, each anti-shake coil 132 of the anti-shake drive portion 13 is respectively disposed on each side of the anti-shake movable portion 12 to form a clearance.

[0168] Optionally, in other examples of the camera module of the present invention, the top ends of the four suspension elements 181 of the suspension portion 18 are respectively connected to the middle of the four sides of the upper cover 112, and the bottom ends of the four suspension elements 181 are respectively connected to the middle of the four sides of the movable carrier 121. Thus, the four suspension elements 181 of the suspension portion 18 can cooperate with each other to ensure that the anti-shake movable portion 12 can smoothly translate and / or rotate within the receiving cavity 1101 of the anti-shake fixing portion 11. In this case, each anti-shake coil 132 of the anti-shake drive portion 13 is respectively disposed at each corner of the anti-shake movable portion 12 to form a clearance.

[0169] It is worth mentioning that the type of the suspension element 181 of the suspension portion 18 is not limited in the camera module of the present invention. For example, the suspension element 181 can be a suspension wire, a spring, a spring sheet, a folded body, etc. (See attached diagram) Figures 8A to 9B Unlike the camera module shown, the attached... Figure 12 In this modified example of the camera module shown, the drive assembly 10 may not have the magnetic suction member 15, and the ball bearing 122 may not be provided between the movable carrier 121 and the upper cover 112. Specifically, with the attached... Figure 11 The camera module shown is similar to the one in the attached... Figure 12 In this specific example of the camera module shown, the drive assembly 10 suspends the stabilization movable part 12 in the receiving cavity 1101 of the stabilization fixed part 11 via the suspension part 18.

[0170] Optionally, in other examples of the camera module of the present invention, the drive assembly 10 includes two suspension portions 18, wherein the top end of the suspension elements 181 of one suspension portion 18 is connected to the upper cover 112 and the bottom end is connected to the movable carrier 121, and the top end of the suspension elements 181 of the other suspension portion 18 is connected to the movable carrier 1212 and the bottom end is connected to the base 111, so that the two suspension portions 18 cooperate with each other to suspend the image stabilization movable part 12 in the receiving cavity 1101 of the image stabilization fixing part 11.

[0171] Appendix Figure 13 Another preferred example of the camera module of the present invention is shown, wherein the magnetic suction member 15 is disposed on the stabilization movable part 12, and the magnetic suction member 15 corresponds to the stabilization magnet 131 to generate a magnetic attraction in the Z-axis direction, causing the stabilization movable part 12 to tend to move closer to the upper cover 112 of the stabilization fixed part 11, wherein the top ends of the suspension elements 181 of the suspension part 18 are connected to the movable carrier 121 of the stabilization movable part 12, and the bottom ends are connected to the base 111 of the stabilization fixed part 11 to prevent the stabilization movable part 12 from moving toward the stabilization fixed part 11. In this way, the stabilization movable part 12 can be suspended in the receiving cavity 1101 of the stabilization fixed part 11.

[0172] Appendix Figures 14A to 16B The diagram shows the current direction and force direction of each of the anti-shake coils 132 of the anti-shake drive unit 13 when the anti-shake movable part 12 translates along the X-axis, translates along the Y-axis, and rotates about the Z-axis, wherein the first coil 1321 and the second coil 1322 are connected in series, the third coil 1323 and the fourth coil 1324 are connected in series, and the fifth coil 1325 and the sixth coil 1326 are connected in series.

[0173] Reference Appendix Figure 14A and Figure 14BWhen a clockwise current is applied to the first coil 1321 and a counterclockwise current is applied to the second coil 1322, the first coil 1321 and the second coil 1322 are subjected to Lorentz force under the action of the magnetic field, causing the image stabilization movable part 12 to drive the photosensitive component 30 to translate in the negative direction of the X-axis for compensation, so as to realize the translational image stabilization of the camera module in the X-axis direction.

[0174] Continue to refer to the appendix Figure 14A Arrow I indicates the direction of current, and symbol F indicates the force on the anti-shake coil 132. During translational anti-shake in the X-axis direction, the current flowing through the first coil 1321 and the second coil 1322 is the same. At this time, the force on the first coil 1321 and the second coil 1322 is the same in magnitude and direction.

[0175] Conversely, when the first coil 1321 is supplied with a counterclockwise current and the second coil 1322 is supplied with a clockwise current, the first coil 1321 and the second coil 1322 are subjected to Lorentz force under the action of the magnetic field, causing the image stabilization movable part 12 to drive the photosensitive component 30 to translate along the positive X-axis for compensation, so as to realize the translational image stabilization of the camera module in the X-axis direction.

[0176] Reference Appendix Figure 15A and Figure 15B When a clockwise current is applied to the third coil 1323, a counterclockwise current is applied to the fourth coil 1324, a clockwise current is applied to the fifth coil 1325, and a counterclockwise current is applied to the sixth coil 1326, the third coil 1323, the fourth coil 1324, the fifth coil 1325, and the sixth coil 1326 are subjected to Lorentz force under the action of a magnetic field. This causes the image stabilization movable part 12 to drive the photosensitive component 30 to translate along the positive Y-axis for compensation, thereby achieving translational image stabilization of the camera module in the Y-axis direction.

[0177] Continue to refer to the appendix Figure 15A Arrow I indicates the direction of current, and symbol F indicates the force on the anti-shake coil 132. During translational anti-shake in the Y-axis direction, the currents supplied to the third coil 1323, the fourth coil 1324, the fifth coil 1325, and the sixth coil 1326 are of the same magnitude. At this time, the forces on the third coil 1323, the fourth coil 1324, the fifth coil 1325, and the sixth coil 1326 are of the same magnitude and in the same direction.

[0178] Conversely, when the third coil 1323 is supplied with a counterclockwise current, the fourth coil 1324 with a clockwise current, the fifth coil 1325 with a counterclockwise current, and the sixth coil 1326 with a clockwise current, the third coil 1323, the fourth coil 1324, the fifth coil 1325, and the sixth coil 1326 are subjected to Lorentz force under the action of the magnetic field. This causes the image stabilization movable part 12 to drive the photosensitive component 30 to translate in the negative direction of the Y-axis for compensation, thereby realizing translational image stabilization of the camera module in the Y-axis direction.

[0179] Reference Appendix Figure 16A and Figure 16B When a clockwise current is applied to the third coil 1323, a counterclockwise current is applied to the fourth coil 1324, a counterclockwise current is applied to the fifth coil 1325, and a clockwise current is applied to the sixth coil 1326, the third coil 1323, the fourth coil 1324, the fifth coil 1325, and the sixth coil 1326 are subjected to Lorentz force under the action of a magnetic field. This causes the image stabilization movable part 12 to drive the photosensitive component 30 to rotate clockwise around the Z-axis for compensation, thereby achieving rotational image stabilization of the camera module in the Z-axis direction.

[0180] Continue to refer to the appendix Figure 16A Arrow I indicates the direction of current, and symbol F indicates the force on the anti-shake coil 132. During the rotational image stabilization process in the Z-axis direction, the currents supplied to the third coil 1323 and the fifth coil 1325 are of the same magnitude but opposite in direction, and the currents supplied to the fourth coil 1324 and the sixth coil 1326 are of the same magnitude but opposite in direction. This results in the second coil group 134 located on the fourth chip side 324 of the photosensitive element 32 and the third coil group 135 located on the second chip side 322 of the photosensitive element 32 experiencing the same magnitude but opposite direction of force. That is, the fifth coil 1325 and the sixth coil 1326 located on the second chip side 322 of the photosensitive element 32 are subjected to a force in the negative direction along the Y-axis, while the third coil 1323 and the fourth coil 1324 located on the fourth chip side 324 of the photosensitive element 32 are subjected to a force in the positive direction along the Y-axis. This enables the image stabilization movable part 12 to rotate around the Z-axis, thereby achieving rotational image stabilization of the camera module.

[0181] Conversely, when the third coil 1323 is supplied with a counterclockwise current, the fourth coil 1324 with a clockwise current, the fifth coil 1325 with a clockwise current, and the sixth coil 1326 with a counterclockwise current, the third coil 1323, the fourth coil 1324, the fifth coil 1325, and the sixth coil 1326 are subjected to Lorentz force under the action of the magnetic field. This causes the image stabilization movable part 12 to drive the photosensitive component 30 to rotate counterclockwise around the Z-axis for compensation, thereby achieving rotational image stabilization of the camera module in the Z-axis direction.

[0182] Furthermore, when the image stabilization movable part 12 moves the photosensitive component 30 along the X-axis, the first sensing element 161 can sense a significant change in the magnetic field and provide feedback on the change. When the image stabilization movable part 12 moves the photosensitive component 30 along the Y-axis and rotates it around the Z-axis, the first sensing element 161 fails to sense a significant change in the magnetic field, while the second sensing element 162 and the third sensing element 163 can sense a significant change in the magnetic field. For the change in the magnetic field during translation along the Y-axis, the average of the sum of the sensing values ​​of the second sensing element 162 and the third sensing element 163 is used as a compensation value. For the change in the magnetic field during rotation around the Z-axis, the average of the difference between the sensing values ​​of the second sensing element 162 and the third sensing element 163 is used as a compensation value, where the sensing value is positive in the positive direction and negative in the negative direction.

[0183] According to another aspect of the present invention, the present invention further provides a driving method for the driving assembly 10, wherein the stabilizing movable part 12 of the driving assembly 10 is suspended in the receiving cavity 1101 of the stabilizing fixed part 11, and the stabilizing magnet 131 and the stabilizing coil 132 of the stabilizing driving part 13 are respectively disposed in one of the stabilizing fixed part 11 and the stabilizing movable part 12, that is, if the stabilizing magnet 131 is disposed in the stabilizing fixed part 11, then the stabilizing coil 132 is disposed in the stabilizing movable part 12, and if the stabilizing magnet 131 is disposed in the stabilizing movable part 12, then the stabilizing coil 132 is disposed in the stabilizing fixed part 11, wherein the driving method includes the following steps:

[0184] (a) When a current in one direction is supplied to the first coil 1321 and a current in the opposite direction is supplied to the second coil 1322, the anti-shake movable part 12 is driven to translate along the X-axis direction within the receiving cavity 1101 of the anti-shake fixed part 11.

[0185] (b) When a current in one direction is supplied to the third coil 1323 and the fifth coil 1325, and a current in the opposite direction is supplied to the fourth coil 1324 and the sixth coil 1326, the anti-shake movable part 12 is driven to translate along the Y-axis direction within the receiving cavity 1101 of the anti-shake fixed part 11; and

[0186] (c) When a current in one direction is supplied to the third coil 1323 and the sixth coil 1326 and a current in the opposite direction is supplied to the fourth coil 1324 and the fifth coil 1325, the anti-shake movable part 12 is driven to rotate around the Z-axis direction in the receiving cavity 1101 of the anti-shake fixed part 11.

[0187] According to another aspect of the present invention, the present invention further provides a method for assembling the drive component 10, wherein the assembly method includes the following steps:

[0188] (A) A plurality of the anti-shake magnets 131 are disposed in one of the anti-shake fixing part 11 and the anti-shake movable part 12, and a plurality of the anti-shake coils 132 are disposed in the other of the anti-shake fixing part 11 and the anti-shake movable part 12; and

[0189] (B) The stabilizing movable part 12 is suspended in the receiving cavity 1101 of the stabilizing fixed part 11, and each of the stabilizing magnets 131 and each of the stabilizing coils 132 correspond to each other to assemble the drive assembly 10.

[0190] For example, in the appendix Figures 1 to 6 In this preferred example of the camera module shown, a plurality of stabilization magnets 131 are respectively disposed on the stabilization fixing part 11, and correspondingly, a plurality of stabilization coils 132 are respectively disposed on the stabilization movable part 12. (See attached...) Figures 8A to 9B In this preferred example of the camera module shown, a plurality of anti-shake magnets 131 are respectively disposed on the anti-shake movable part 12, and correspondingly, a plurality of anti-shake coils 132 are respectively disposed on the anti-shake fixed part 11.

[0191] Further, in a preferred example where multiple anti-shake magnets 131 are respectively disposed on the anti-shake fixing part 11 and multiple anti-shake coils 132 are respectively disposed on the anti-shake movable part 12, step (A) further includes the steps of: first, disposing the electrical connection part 123 and the anti-shake coil 132 on the movable carrier 121 respectively; and second, electrically connecting the anti-shake coil 132 to the electrical connection part 123. Specifically, the electrical connection part 123 can be attached to the back surface 1212 of the movable carrier 121, and the anti-shake coil 132 can be attached to the front surface 1212 of the movable carrier 121, with the anti-shake coil 132 and the electrical connection part 123 connected by a connecting wire.

[0192] Optionally, in a preferred example where multiple anti-shake magnets 131 are respectively disposed on the anti-shake fixing part 11 and multiple anti-shake coils 132 are respectively disposed on the anti-shake movable part 12, step (A) further includes the steps of: first, attaching the anti-shake coils 132 to the electrical connection part 123, and second, attaching the electrical connection part 123 to the movable carrier 121. For example, the electrical connection part 123 may be attached to the carrier back surface 1212 of the movable carrier 121.

[0193] Preferably, the assembly method of the present invention further includes: (C) covering the magnetic conductive member 14 on the back side of the anti-shake magnet 131, so that it faces the anti-shake coil 132, so as to strengthen the magnetic field from the magnetic conductive member 14 toward the anti-shake coil 132.

[0194] For example, in the appendix Figures 1 to 6 In this preferred example of the camera module shown, the magnetically conductive member 14 is positioned above the image stabilizing magnet 131. This allows the magnetically conductive member 14 to not only strengthen the magnetic field towards the image stabilizing coil 132 but also reduce the magnetic field strength spilling over to the lens carrier 21, thereby preventing magnetic interference to the lens carrier 21. (See attached...) Figure 10 In this preferred example of the camera module shown, the magnetically conductive member 14 is positioned below the anti-shake magnet 131, thereby enabling the magnetically conductive member 14 to reinforce the magnetic field in the direction of the anti-shake coil 132.

[0195] In step (B), the drive assembly 10 can suspend the anti-shake movable part 12 in the receiving cavity 1101 of the anti-shake fixed part 11 by means of the cooperation between the magnetic suction member 15 and the support part 17.

[0196] For example, in a preferred example where multiple anti-shake magnets 131 are respectively disposed in the anti-shake fixing part 11 and multiple anti-shake coils 132 are respectively disposed in the anti-shake movable part 12, on the one hand, the drive assembly 109 may be provided with multiple magnetic suction members 15 in the anti-shake movable part 12, and these magnetic suction members 15 and the anti-shake magnets 131 cooperate with each other to generate magnetic attraction in the Z-axis direction. On the other hand, the retaining groove 1215 of the support part 17 is formed in the movable carrier 121 of the anti-shake movable part 12, and a portion of the ball bearing 122 of the support part 17 is held in the retaining groove 1215, while the other portion abuts against the anti-shake fixing part 11. Thus, the anti-shake movable part 12 can be suspended in the receiving cavity 1101 of the anti-shake fixing part 11 by the cooperation of the magnetic suction members 15 and the support part 17.

The objectives of the present invention have been fully and effectively achieved.
