Description

Technical Field

[0001] The embodiments of the present invention relate to the technical field of camera devices, and in particular to a camera module, a camera and an electronic device. Background Art

[0002] The aperture (adjustable diaphragm) is used to change the amount of light that enters the optical system to participate in imaging. By setting the aperture in the camera module, the camera module can be adapted to the shooting needs of different light and dark scenes by adjusting the size of the aperture; the focus mechanism can achieve the focus of the camera module by changing the position of the lens, so that the camera module can shoot the target object more clearly. The aperture and focus mechanism are used together to improve the shooting performance of the camera module. Therefore, the camera module with the aperture and focus mechanism is applied to electronic devices, such as smart phones, tablet computers, etc., and is favored by consumers.

[0003] The blade drive device drives multiple blades to move so that the size of the opening surrounded by these blades can be changed, which can be applied to different optical units on the camera, such as shutters, apertures or filters. In an optical system that uses a lens drive device to move the lens to achieve adjustment, the blade drive device may hinder the movement and configuration of the lens drive device due to factors such as size, weight and multi-directional protrusion caused by the assembly direction. Although a smaller blade drive mechanism made of shape memory metal can be used to overcome the problems of weight and volume, when the size of the opening surrounded by the blades needs to have a larger change, the length of the shape memory metal needs to be increased, which still cannot effectively solve the various problems caused by the large volume and weight of the blade drive mechanism.

[0004] In addition, since it is necessary to avoid interference between the blade drive mechanism and the focus mechanism, the servo control of the focus mechanism may be affected. Alternatively, in order for the blade drive mechanism to move accordingly to properly block light when the lens moves, the weight of the blade drive mechanism needs to be evenly distributed over the entire circumference. The above design scheme is difficult, and the reliability of the product completed based on the above design scheme cannot be guaranteed.

[0005] Therefore, there is an urgent need in the art for a camera module that can solve the above technical problems. Summary of the invention

[0097] One embodiment of the present invention relates to a camera module 1000, such as Figures 1 to 7 As shown, it includes: a lens 100; a lens supporting frame 200, which is sleeved on the outer edge of the lens 100; a base 300, which is sleeved on the outer side of the lens supporting frame 200; a first driving member 310, which is arranged on the base 300; a second driving member 210, which is arranged on the lens supporting frame 200 and is arranged opposite to the first driving member 310 to drive the lens supporting frame 200 to drive the lens 100 to move along the optical axis; a blade driving frame 400, which is movably supported on the base 300 and sleeved on the outer side of the lens 100; a spherical supporting member 320, which is clamped between the blade driving frame 400 and the base 300; a blade supporting portion 110, which is arranged at one end of the lens 100 away from the base; a blade driving ring 500, which is arranged on the blade driving frame 400 and is rotatably buckled with the blade driving frame 400 with the optical axis as the rotating axis. On the blade supporting portion 110; a plurality of shading blades 600, the plurality of shading blades 600 are located between the blade driving ring 500 and the blade supporting portion 110, the plurality of shading blades 600 are arranged on the blade driving ring 500 along the circumference of the blade driving ring 500 and are spaced apart from each other, the plurality of shading blades 600 are rotatably connected to the blade supporting portion 110 at one end, and slidably connected to the blade driving ring 500 at the other end; a third driving member 410, which is arranged on the blade driving frame 400 and is opposite to the first driving member 310; the third driving member 410 interacts with the first driving member 310 to drive the blade driving frame 400 to rotate relative to the base 300 with the optical axis as the rotating axis, and the blade driving frame 400 drives the blade driving ring 500 to rotate, thereby driving the plurality of shading blades 600 to gather or separate.

[0098] Compared with the related art, the embodiment of the present invention is that the first driving member 310 is provided on the base 300, and the second driving member 210 is provided on the lens support frame 200. The first driving member 310 cooperates with the second driving member 210 to drive the lens support frame 200 to focus and move along the optical axis; the blade driving frame 400 is movable relative to the base 300, and the blade driving frame 400 is provided with a third driving member 410. The first driving member 310 is also used to cooperate with the third driving member 410 to drive the blade driving frame 400 to rotate with the optical axis as the rotating axis. When the blade driving frame 400 rotates, it drives the blade driving ring 500 to rotate synchronously, and the blade driving ring 500 drives the multiple shading blades 600 to gather or separate, thereby realizing the adjustment of the size of the opening surrounded by the shading blades 600. That is to say, the driving components for driving the multiple shading blades 600 and driving the lens 100 to focus are both the first driving component 310. In this way, the number of components of the camera module 1000 can be reduced, thereby reducing the volume and weight of the camera module 1000 and avoiding interference between the focusing structure in the camera module 1000 and the power mechanism for driving the multiple shading blades 600.

[0099] More specifically, the base 300, the blade drive frame 400, the blade support 110, the plurality of shading blades 600 and the blade drive ring 500 are arranged in sequence from the image side to the object side of the camera module 1000, that is, these components are arranged in sequence along the optical axis, so that the camera module 1000 can be assembled along the extension direction of the optical axis, thereby reducing the difficulty of assembly and avoiding protrusions in multiple directions.

[0100] The implementation details of the camera module of this embodiment are described in detail below. The following content is only provided for easy understanding of the implementation details and is not necessary for implementing this solution.

[0101] It can be understood that the lens 100 includes a lens 120 and a lens barrel 130, and the lens 120 is fixed on the inner wall of the lens barrel 130. The lens barrel 130 is used to protect the lens 120 and prevent the lens 120 from being damaged. Secondly, the lens barrel 130 can also provide a space for connecting with the lens support frame 200, that is, the lens support frame 200 is mounted and fixed on the outer wall of the lens barrel 130, and the blade support part 110 is arranged on the object side of the lens barrel 130.

[0102] Please refer to Figure 8In this embodiment, the side of the base 300 facing the blade drive frame 400 has at least three first accommodating grooves 330 extending in an arc shape, and the side of the blade drive frame 400 facing the base 300 has at least three second accommodating grooves 420 extending in an arc shape. The first accommodating grooves 330 and the second accommodating grooves 420 are arranged one by one and enclose a accommodating space. There are multiple spherical support members 320, and at least one spherical support member 320 is accommodated in each accommodating space, and the spherical support member 320 abuts against the inner walls of the first accommodating groove 330 and the second accommodating groove 420 at the same time. That is to say, when the first driving member 310 cooperates with the third driving member 410 to drive the blade drive frame 400 to rotate, the spherical support member 320 can play a role in supporting the blade drive frame 400, and can also smoothly rotate the blade drive frame 400 by virtue of its own rolling. Optionally, the first accommodating groove 330 and the second accommodating groove 420 can be set to four, and the first accommodating groove 330 and the second accommodating groove 420 can be arranged one by one relative to each other, and the spherical support member 320 can also be correspondingly set to four, and each of the accommodating spaces can accommodate one spherical support member 320.

[0103] Specifically, the first accommodating grooves 330 and the second accommodating grooves 420 are arranged at intervals around the optical axis. The plurality of first accommodating grooves 330 may be arranged on the same circular trajectory, or may not be arranged on the same circular trajectory, but are preferably arranged on the same circular trajectory; the plurality of second accommodating grooves 420 are similar, and will not be described in detail.

[0104] In other feasible embodiments, the first receiving groove 330 and the second receiving groove 420 may be provided in three numbers, and the spherical support member 320 may be provided in three numbers, and each of the receiving spaces may accommodate one spherical support member 320. In this way, the blade drive frame 400 can be kept stable while being able to rotate relative to the base 300 when subjected to force, and the blade drive frame 400 can be prevented from turning over; in addition, the number of spherical support members 320 can be further reduced, and the weight of the camera module 1000 can be further reduced.

[0105] It should be noted that the specific number and position of the first accommodating groove 330, the second accommodating groove 420 and the spherical support member 320 can be arranged by those skilled in the art according to actual force requirements, and the present invention does not make any special limitations.

[0106] Furthermore, the first driving member 310 is a magnetic steel, the second driving member 210 is a focusing coil, and the third driving member 410 is a blade driving coil. When the focusing coil is energized, the magnetic steel drives the focusing coil to move along the optical axis to drive the lens support frame 200 to focus and move along the optical axis; when the blade driving coil is energized, the magnetic steel drives the blade energized coil to rotate with the optical axis as the axis to drive the blade driving frame 400 to rotate with the optical axis as the axis. Specifically, when the focusing coil and the blade driving coil are energized, a Lorentz force is generated between the magnetic steel and the blade driving coil, and the Lorentz force drives the focusing coil and the blade driving coil to move. It is sufficient to turn on the power when focusing and blade movement are required, thereby improving the controllability of the camera module.

[0107] In this embodiment, the focus coil is circumferentially arranged around the outer edge of the lens support frame 200. In this embodiment, the lens support frame 200 is annular, and the focus coil is wound around the outer wall of the lens support frame 200. When the focus coil is energized, a Lorentz force is generated between the focus coil and the magnetic steel. Since the magnetic steel is fixed on the base 300, the focus coil drives the lens support frame 200 to move.

[0108] More specifically, there are a plurality of magnetic steels, which are spaced apart around the optical axis on the base 300 and located on a side of the base 300 facing the lens support frame 200 .

[0109] Alternatively, in other feasible embodiments, there are multiple focus coils, and the multiple focus coils are arranged on the lens support frame 200 at intervals along the circumference of the lens support frame 200. For example, there are four focus coils, and the four focus coils surround the outer circumference of the lens support frame 200 and are arranged on the lens support frame 200 at equal intervals. When the focus coils are energized, the four focus coils are all subjected to force to drive the lens support frame 200 to move. It can be understood that the focus coils can also be other numbers, such as two, three or more, and preferably multiple focus coils are arranged on the lens support frame 200 at equal intervals around the optical axis, so that the force on the lens support frame 200 can be more balanced, thereby improving the stability and reliability of the camera module.

[0110] Further, there are multiple blade drive coils, and the multiple blade drive coils are arranged on the blade drive frame 400 at intervals along the circumference of the blade drive frame 400. Similarly, there can be four blade drive coils, and the four blade drive coils are arranged on the blade drive frame 400 at intervals. When the blade drive coil is energized, Lorentz force is generated between the blade drive coil and the magnetic steel, and the four blade drive coils are forced to drive the blade drive frame 400 to rotate with the optical axis as the rotation axis.

[0111] It should be noted that the lens support frame 200 is translated along the optical axis by the Lorentz force, while the blade drive frame 400 is rotated with the optical axis as the rotation axis by the Lorentz force. This is because the directions of the Lorentz forces on the lens support frame 200 and the blade drive frame 400 are different, and the reason is that the focusing coil and the blade drive coil are set in different ways. Specifically, it can be determined according to the left-hand rule.

[0112] Furthermore, a first flexible circuit board 220 is provided on the lens support frame 200, and a second flexible circuit board 430 is provided on the blade drive frame 400. The first flexible circuit board 220 and the second flexible circuit board 430 are electrically connected. In this way, when power is turned on, the first flexible circuit board 220 and the second flexible circuit board 430 can be powered on at the same time to achieve synchronous adjustment of focus and aperture size.

[0113] Please refer again Figure 3 and Figure 4 In this embodiment, it is also necessary to detect the focus movement amount of the lens support frame 200 and the rotation amount of the blade drive frame 400 to accurately control the focus and aperture adjustment of the camera module. Specifically, the lens support frame 200 is provided with a first position detection component 230, and the first flexible circuit board 220 is electrically connected to a first sensing element 221. When the lens support frame 200 moves, the first sensing element 221 determines the focus movement amount of the lens support frame 200 by detecting the change in the relative position of the first position detection component 230. For example, the first position detection component 230 can be a magnet, and the first sensing element 221 can be a Hall element. When the lens support frame 200 moves along the optical axis, the magnet moves with the lens support frame 200, and the position of the Hall element is relatively fixed, resulting in a continuous change in the magnetic field at the position of the Hall element, which is mainly reflected in the continuous change in the magnetic flux passing through the Hall element, thereby detecting the movement amount of the lens support frame 200.

[0114] The second flexible circuit board 430 is electrically connected to a second sensing element 431. When the blade drive frame 400 rotates, the second sensing element 431 determines the rotation angle of the blade drive frame 400 by detecting the relative position of the first driving member 310. For example, when the first driving member 310 is a magnetic member (i.e., a magnet), the second sensing element 431 may be a Hall element. When the first driving member 310 drives the blade drive frame 400 to rotate and drives the second sensing element 431 to move, the second sensing element 431 determines the rotation angle of the blade drive frame 400 by detecting the change in magnetic flux caused by the first driving member 310 at different positions.

[0115] Furthermore, the lens support frame 200 is also provided with a first leaf spring 240 and a second leaf spring 250, and the first leaf spring 240 and the second leaf spring 250 are respectively fixed to the object side surface and the image side surface of the lens support frame 200. At the same time, the first leaf spring 240 and the second leaf spring 250 are also respectively fixed to the object side surface and the image side surface of the base 300, so that the lens support frame 200 is suspended and fixed on the base 300.

[0116] In this embodiment, in order to prevent the blade drive ring 500 from interfering with the lens 100 when the lens 100 is focused, the blade drive ring 500 needs to be movable along the optical axis. Specifically, a connecting arm 510 is provided on the blade drive ring 500, and a connecting groove 440 is provided on the blade drive frame 400. The connecting arm 510 can be slidably extended into the connecting groove 440 along the optical axis so that the blade drive ring 500 and the blade drive frame 400 are clamped and connected. Specifically, the connecting groove 440 passes through the blade drive frame 400 in the direction along the optical axis, but clamps the connecting arm 510 in the direction perpendicular to the optical axis, that is, the connecting groove 440 is a through groove extending along the optical axis. In this way, when the blade drive frame 400 rotates, the blade drive ring 500 can be driven to rotate with the optical axis as the rotating axis, and the movement of the blade drive ring 500 in the extending direction of the optical axis will not be affected. Since the blade drive ring 500 is sleeved on the outside of the lens 100, when the lens 100 moves along the optical axis in a direction away from the base 300 driven by the lens support frame 200, the outer edge of the lens barrel 130 pushes the blade drive ring 500 to move in the same direction, and at this time the connecting arm 510 slides in the connecting groove 440.

[0117] Optionally, there are multiple connecting arms 510, and there are multiple connecting slots 440, and the multiple connecting arms 510 and the multiple connecting slots 440 are connected in a one-to-one corresponding manner. Preferably, two connecting arms 510 can be provided, and they are respectively provided on two opposite sides of the blade drive ring 500, and two connecting slots 440 can be provided, and they are respectively provided on two opposite sides of the blade drive frame 400. In this way, the stability between the blade drive frame 400 and the blade drive ring 500 can be improved, and the manufacturing difficulty of the camera module will not be increased.

[0118] Please refer to Figures 9a to 9c Driven by the blade drive frame 400, the blade drive ring 500 rotates and drives the plurality of light shielding blades 600 to gather or separate, thereby adjusting the aperture size. Figure 9a It is a schematic diagram of the state of the camera module 1000 when the plurality of light-shielding blades 600 are gathered to the extreme position; Figure 9b is a schematic diagram of the state of the plurality of light shielding blades 600 of the camera module 1000 in the process of separation; Fig.9c It is a schematic diagram of the state of the camera module 1000 when the multiple shading blades 600 are separated to the extreme position.

[0119] It can be understood that the blade support portion 110, the blade drive ring 500 and the plurality of shading blades 600 together constitute an adjustable aperture. When the blade drive ring 500 is driven to rotate, the blade drive ring 500 drives the plurality of shading blades 600 to move to change the aperture of the adjustable aperture, thereby adjusting the luminous flux that can pass through the adjustable aperture. When the blade drive coil is energized, the blade drive frame 400 rotates to drive the blade drive ring 500 to rotate, and the blade drive ring 500 drives the plurality of shading blades 600 to gather together, causing the opening surrounded by the plurality of shading blades 600 to become smaller, thereby reducing the amount of light entering the camera module 1000, or the blade drive ring 500 drives the plurality of shading blades 600 to separate, causing the opening surrounded by the plurality of shading blades 600 to become larger, thereby increasing the amount of light entering the camera module 1000. In some cases, due to the influence of unexpected movements or vibrations, the blade drive frame 400 may also rotate, resulting in an unexpected change in the amount of light entering the camera module. To avoid similar situations, the camera module of this embodiment also includes a blade holding component 450, which is fixed to the blade drive frame 400. The blade holding component 450 is used to cooperate with the first driving member 310 to keep the blade drive frame 400 in the initial position when the power is off. In this way, when the blade drive coil is not energized, even if the blade drive frame 400 rotates due to unexpected vibrations, causing the multiple blades 600 to move, the blade holding component 450 and the first driving member 310 can cooperate with each other to return the blade drive frame 400 to the initial position, thereby keeping the position of the multiple light-shielding blades 600 stable, making the size and shape of the opening surrounded by the multiple light-shielding blades 600 relatively stable, and thus keeping the amount of light entering the camera module stable.

[0120] Specifically, the blade holding component 450 and the first driving member 310 are both magnetic members, and the first driving member 310 attracts the blade holding component 450 to maintain the angle of the blade driving frame 400 relative to the base 300. More specifically, the first driving member 310 in this embodiment is a magnetic steel, and the blade holding component 450 is a yoke, and the magnetic steel attracts the yoke through magnetic force, so that the position of the blade driving frame 400 remains stable relative to the base 300. In the power-off state, when the blade driving frame 400 is rotated by unexpected action or vibration, the blade driving frame 400 will automatically reset under the action of the attraction of the magnetic steel and the yoke, so that the multiple light-shielding blades 600 remain in a relatively stable position, thereby maintaining the size of the aperture. In addition, due to the action of the magnetic steel and the yoke, the influence of unexpected action or vibration on the blade driving frame 400 can also be reduced.

[0121] It can be understood that, in this embodiment, the base 300 and the blade drive frame 400 are relatively fixed in the direction of extension of the optical axis via the attraction between the first drive member 310 and the blade holding component 450. Specifically, the first drive member 310 attracts the blade holding component 450, and since the blade holding component 450 is fixed to the blade drive frame 400, the blade drive frame 400 is driven by the blade holding component 450 and fixed relative to the base 300. It can be known from the above content that a plurality of the spherical support members 320 are clamped between the base 300 and the blade drive frame 400, and the spherical support members 320 can roll relative to the base 300 and the blade drive frame 400. Since the movement trajectory of the spherical support members 320 is constrained by the first accommodating groove 330 and the second accommodating groove 420, when the blade drive frame 400 is acted upon by the Lorentz force between the first drive member 310 and the third drive member 410, the blade drive frame 400 can rotate relative to the base 300 in a plane perpendicular to the optical axis and with the optical axis as the rotation axis.

[0122] Optionally, the blade holding component 450 can be multiple and arranged at circumferential intervals around the blade driving frame 400. In this way, the effect of the attraction between the magnetic steel and the magnetic yoke can be increased, and the stability of the position of the multiple light-shielding blades 600 can be improved. Preferably, the length of the blade holding component 450 is not less than 20% of the length of the first driving member 310, so that the attraction between each pair of the magnetic yoke and the magnetic steel can be increased, and the stability of the position of the multiple light-shielding blades 600 can be improved; in addition, by adjusting the length of the magnetic yoke, the size of the attraction can also be changed, thereby changing the reset ability of the aperture. More preferably, when the blade holding component 450 and the first driving member 310 are facing each other, the line connecting the geometric center of the blade holding component 450 and the geometric center of the first driving member 310 is parallel to the optical axis. The arrangement of the magnetic yoke and the magnetic steel in this position can more effectively utilize the effect of magnetic force than other arrangements.

[0123] For the first driving member 310 and the blade holding component 450, the position of the blade driving frame 400 is fixed by the magnetic force of the two, and the effect is similar to fixing it with a spring. Therefore, the interaction force between the first driving member 310 and the blade holding component 450 can be adjusted by adjusting the size, shape, position and manufacturing material of the first driving member 310 and the blade holding component 450, which is similar to adjusting the elastic coefficient of the spring, thereby changing the position stability of the blade driving frame 400.

[0124] It is understandable that in this embodiment, in order to reduce the manufacturing difficulty and testing difficulty of the camera module 1000, the magnetic steel used in the first driving member 310 can be a magnetic steel with exactly the same specifications (such as size, shape and material, etc.); when the second driving member 210 is multiple, the focusing coil used by the second driving member 210 can also be a coil with exactly the same specifications; the blade driving coil used by the third driving member 410 can also be a coil with exactly the same specifications; the yoke used by the blade holding component 450 can also be a yoke with exactly the same specifications. In some cases, when the first driving member 310 needs to use different magnetic steels, the configuration of its specifications, number and position can be adjusted by those skilled in the art according to the force conditions. The same applies to the second driving member 210, the third driving member 410 and the blade holding component 450, which will not be repeated here.

[0125] Furthermore, in order to improve the position stability of the first driving member 310, grooves corresponding in number and profile to the first driving member 310 may be provided on the base 300, and the first driving member 310 may be provided in the grooves one by one, and the first driving member 310 may be limited and fixed by the inner wall of the groove. For the second driving member 210, when the second driving member 210 is a focusing coil arranged around the outer periphery of the lens support frame 200, the lens support frame 200 may be provided with a circumferentially extending groove at the outer edge, and the second driving member 210 may be provided in the circumferentially extending groove; when the second driving member 200 is a plurality of focusing coils arranged at intervals, grooves corresponding in number and profile to the plurality of focusing coils may be provided on the lens support frame 200, and the second driving member 210 may be provided in the grooves one by one, and the second driving member 210 may be limited and fixed by the inner wall of the groove. For the third driving member 410, grooves corresponding in number and profile to the third driving member 410 can be provided on the blade driving frame 400, and then the third driving member 410 can be provided in the grooves one by one, and the inner wall of the groove can be used to limit and fix the third driving member 410. The blade holding component 450 can adopt the same configuration as the third driving member 410. In addition, in general, the size of the blade holding component 450 is smaller than that of the third driving member 410. Therefore, a groove for installing the blade holding component 450 can be provided on the bottom wall of the groove for installing the third driving member 410. In this way, while meeting the installation requirements of the third driving member 410 and the blade holding component 450, the third driving member 410 can also be used to limit the blade holding component 450 to prevent the blade holding component 450 from detaching from the blade driving frame 400.

[0126] In other feasible embodiments, the magnetic yoke may also be replaced by magnetic fluid. The principle is the same as that of using the magnetic yoke, which will not be repeated here.

[0127] Please refer to Figures 10 to 12 In the present embodiment, the blade drive ring 500 is provided with a plurality of through grooves 520, and the plurality of through grooves 520 are arranged at intervals along the circumference of the blade drive ring 500; each of the through grooves 520 extends from the outer edge to the inner edge of the blade drive ring 500, and the extension direction of each of the through grooves 520 forms an angle with the radial direction of the blade drive ring 500; the plurality of light-shielding blades 600 are all in the shape of arc-shaped sheets, and a guide portion 610 is provided at one end of the plurality of light-shielding blades 600, and the guide portions 610 of the plurality of light-shielding blades 600 correspond one to one and can be slidably extended into the through groove 520. In this way, when the blade drive ring 500 rotates, the guide portion 610 slides along the through groove 520 under the constraint of the inner wall of the through groove 520, thereby changing the size and shape of the opening surrounded by the multiple shading blades 600, thereby changing the amount of light entering the camera module.

[0128] Furthermore, the inner walls of the plurality of through slots 520 are provided with a limiting portion 521 at a position close to the optical axis, and the limiting portion 521 is used to limit the moving range of the guide portion 610. In fact, the limiting portion 521 reduces the size of the through slot 520 at a position close to the optical axis, and when the guide portion 610 moves to the limiting portion 521, it is blocked by the limiting portion 521, and the guide portion 610 will not be separated from the through slot 520. Furthermore, the through slot 520 may also be provided with a limiting portion 521 at a position away from the optical axis, so that the guide portion 610 can only slide in the through slot 520.

[0129] Optionally, the guide portion 610 may be a protrusion protruding from the surface of the shading blade 600. The specific shape and size of the protrusion may be set according to actual conditions. Considering the influence of resistance, the guide portion 610 may preferably be a cylindrical structure; when there are other special requirements, the guide portion 610 may also be appropriately adjusted to other shapes.

[0130] Please refer to Fig.13In the present embodiment, the blade support portion 110 is provided with a plurality of positioning holes 111 spaced apart along the circumferential direction, and the other ends of the plurality of shading blades 600 are each provided with a positioning portion 620, and the positioning portion 620 is located on the object side surface of the shading blade 600, and the positioning portions 620 of the plurality of shading blades 600 correspond to each other one by one and can be rotatably extended into the positioning hole 111. That is to say, the image side surface of each of the light-shielding blades 600 is provided with the positioning portion 620, and the positioning portion 620 can be rotatably extended into the positioning hole 111. When the blade driving ring 500 rotates, the inner wall of the through groove 520 applies force to the guide portion 610, thereby driving the multiple light-shielding blades 600 to move. Since the other ends of the multiple light-shielding blades 600 are constrained by the blade supporting portion 110 via the positioning portion 620, but can still rotate, the multiple light-shielding blades 600 rotate around the axis of the corresponding positioning hole 111 as the rotation axis and gather or separate, thereby realizing the change of the aperture size.

[0131] In this embodiment, the blade drive ring 500 is annular, the plurality of shading blades 600 are arc-shaped, and the length of the shading blades is 30% to 60% of the circumference of the blade drive ring. In this way, the shading blades 600 can have a sufficient length while maintaining a relatively light weight, and different shading blades 600 can be prevented from interfering with each other during movement. The multiple light-shielding blades 600 in this embodiment are stacked in sequence and arranged in a circular ring shape. Specifically, the guide portion 610 of the first light-shielding blade 600 extends into one of the through grooves 520, and the positioning portion 620 at the other end extends into the positioning hole 111, the object side surface of the end of the second light-shielding blade 600 provided with the guide portion 610 is attached to the image side surface of the end of the first light-shielding blade 600 provided with the positioning portion 620, and the guide portion 610 of the second light-shielding blade 600 extends into another through groove 520, and the positioning portion 620 of the second light-shielding blade 600 extends into another positioning hole 111, and so on, all the light-shielding blades 600 form a circular ring.

[0132] Furthermore, the orthographic projection area of ​​the shading blade 600 on the plane perpendicular to the optical axis is the first area, and the orthographic projection area of ​​the fan-shaped arc with the edge of the shading blade 600 away from the optical axis on the plane perpendicular to the optical axis is the second area; the first area is 40% to 70% of the second area. In this way, the weight of the plurality of shading blades 600 can be made lighter, and interference between different shading blades 600 can also be avoided.

[0133] Optionally, the number of the shading blades 600 can be adjusted according to actual needs. Generally speaking, the more the number of the shading blades 600 is, the closer the opening surrounded by the shading blades 600 is to a circle. Considering the weight and manufacturing cost of the camera module, the number of the shading blades 600 can be set to five to seven.

[0134] Please refer again Figure 6 and Figure 7 In the present embodiment, the blade support portion 110 is in the shape of a groove, and the groove opening of the blade support portion 110 is away from the base 300. A driving ring pressure plate 112 is fixedly provided on the edge of the blade support portion 110 surrounding the groove opening. The driving ring pressure plate 112, the blade driving ring 500 and the blade support portion 110 form a blade chamber 113. The multiple shading blades 600 are located in the blade chamber 113. The driving ring pressure plate 112 is used to limit the position of the blade driving ring 500 in the optical axis direction to prevent the blade driving ring 500 and the lens 100 from interfering with each other and hindering the rotation of the blade driving ring 500.

[0135] Please refer again Figures 3 to 5 In this embodiment, the focus mechanism 30 of the camera module 1000 may include the first driving member 310, the second driving member 210 and the lens support frame 200; the blade driving mechanism 40 of the camera module 1000 may include the first driving member 310, the third driving member 410, the blade driving frame 400, the blade driving ring 500 and the blade supporting portion 110. The driving sources of the focus mechanism 30 and the blade driving mechanism 40 are both the first driving member 310.

[0136] In this embodiment, the camera module 1000 also includes a housing 700 having a storage space, and the base 300, the lens support frame 200 and the blade drive frame 400 are located in the storage space. The housing 700 has a first central through hole 710, and the first central through hole 710 is used to expose the blade drive ring 500, the plurality of light-shielding blades 600 and the blade support portion 110. The housing 700 is made of a magnetic material. The housing 700 is made of a magnetic material, and the focusing coil, the blade drive coil and the magnetic steel can be enclosed in a closed magnetic circuit to improve the overall magnetism.

[0137] Another embodiment of the present invention relates to a camera module 1000, such as Figures 14 to 17As shown, the camera module 1000 of this embodiment is substantially the same as the previous embodiment, the main difference being that the camera module 1000 of this embodiment further includes an anti-shake mechanism 800 and a sensor assembly 810 disposed on the anti-shake mechanism 800, the anti-shake mechanism 800 being located on the image side of the base 300, and the anti-shake mechanism 800 being used to drive the sensor assembly 810 to achieve anti-shake.

[0138] Compared with the previous embodiment, in addition to being able to achieve focus in the direction of the optical axis and to achieve aperture adjustment through the multiple shading blades 600, this embodiment can also use the anti-shake mechanism 800 to perform shake correction on the sensor component 810 in a direction perpendicular to the optical axis, which can further improve the shooting effect of the camera module 1000. In addition, since the drive of the sensor component 810 by the anti-shake mechanism 800 and the drive of the lens 100 by the first drive member 310 are independent of each other, the changes caused by the drive of the first drive member 310 in focus and aperture have no effect on the drive of the anti-shake mechanism 800 in anti-shake. In other words, the shake correction of the sensor component 810 by the anti-shake mechanism 800 has no effect on the drive of the first drive member 310. In this way, in the performance evaluation of the camera module 1000, the performance of the focusing mechanism, the blade drive mechanism and the anti-shake mechanism 800 can be tested independently, which can reduce the difficulty of testing the camera module. The camera module of the present invention has improved reliability due to its simplified structure, and at the same time improves the configuration of components to reduce the failure rate.

[0139] Please refer again Fig.17 Specifically, the camera module 1000 further includes a bottom shell 720, which cooperates with the outer shell 700 to surround and fix the lens 100, the focusing mechanism, the blade driving mechanism and the anti-shake mechanism 800. Preferably, the bottom shell 720 can also be made of magnetic material.

[0140] In this embodiment, the anti-shake mechanism 800 includes an anti-shake base 820 and a movable bracket 830, wherein the movable bracket 830 is located at the object side of the anti-shake base 820 and is movable relative to the anti-shake base 820 in a direction perpendicular to the optical axis, and the sensor assembly 810 is fixed to the movable bracket 830. Thus, the movable bracket 830 moves to drive the sensor assembly 810 to move, thereby realizing the anti-shake function of the camera module 1000.

[0141] Specifically, the anti-shake base 820 is provided with a plurality of anti-shake magnets 821 arranged at intervals around the optical axis, the movable bracket 830 is provided with a plurality of fixed yokes 831 arranged at intervals around the optical axis, at least three balls 833 are sandwiched between the anti-shake base 820 and the movable bracket 830, and the anti-shake magnets 821 and the fixed yokes 831 attract each other to bring the anti-shake base 820 and the movable bracket 830 closer to each other, thereby clamping all the balls 833. The balls 833 are spherical, so when the balls 833 roll, the movable bracket 830 is movable relative to the anti-shake base 820.

[0142] More specifically, the anti-shake base 820 is provided with a plurality of first receiving grooves 822, the movable bracket 830 is provided with a plurality of second receiving grooves (not shown in the figure), the plurality of balls 833 correspond to the plurality of first receiving grooves 822 one by one and are located in the first receiving grooves 822, and the plurality of second receiving grooves correspond to the plurality of first receiving grooves 822 one by one. By using the receiving grooves to accommodate the balls 833, the movement range of the balls 833 can be limited, the balls 833 can be prevented from falling off, and the stability of the camera module 1000 can be improved.

[0143] In this embodiment, each of the first receiving grooves 822 is provided with a first gasket 822a, and each of the second receiving grooves is provided with a second gasket 832a. Both the first gasket 822a and the second gasket 832a are used to support the ball 833.

[0144] In this embodiment, the anti-shake mechanism 800 includes a coil support 840 fixed on the movable support 830, and the coil support 840 is provided with a plurality of anti-shake coils (not shown in the figure) arranged around the optical axis at intervals, and the plurality of anti-shake coils and the plurality of anti-shake magnets 821 correspond to each other one by one and are arranged relatively. When the anti-shake coil is energized, a Lorentz magnetic force is generated between the anti-shake coil and the anti-shake magnet 822, so that the coil support 840 moves in a direction perpendicular to the optical axis, and then drives the movable support 830 to move synchronously. When the movable support 830 moves, the sensor assembly 810 moves with the movable support 830, thereby realizing anti-shake of the camera module 1000.

[0145] That is to say, the anti-shake base 820 and the movable bracket 830 are relatively fixed in the extension direction of the optical axis via the attraction between the anti-shake magnet 821 and the fixed magnetic yoke 831, and the ball 833 can roll in the first accommodating groove 822 and the second accommodating groove, that is, the ball 833 can roll relative to the anti-shake base 820 and the movable bracket 830. When the movable bracket 830 is acted upon by the Lorentz force between the anti-shake magnet 821 and the anti-shake coil, the movable bracket 830 can move relative to the anti-shake base 820 in a plane perpendicular to the optical axis, thereby allowing the sensor assembly 810 to move in a plane perpendicular to the optical axis, thereby achieving anti-shake.

[0146] Specifically, in this embodiment, the camera module 1000 supplies power to the multiple anti-shake coils through the circuit board 850.

[0147] In this embodiment, the anti-shake base 820 is provided with a mounting hole 823, and a damping member 823a is provided in the mounting hole 823. The damping member 823a passes through the mounting hole 823 and contacts the bottom shell 720 and the sensor assembly 810 respectively. More specifically, the bottom shell 720 and the sensor assembly 810 clamp the damping member 823a to slightly deform the damping member 823a. In this way, the damping member 823a can provide resistance when the sensor assembly 810 moves, slowing down the movement speed of the sensor assembly 810, thereby avoiding unnecessary vibration caused by the excessive movement of the sensor assembly 810 during the anti-shake process.

[0148] Exemplarily, in this embodiment, the number of the mounting holes 823 and the damping member 823a is four, and they are all arranged around the optical axis at intervals. The damping member 823a is made of rubber. It is understandable that the mounting holes 823 and the damping member 823a can be set to other numbers, and the damping member 823a can also be made of silicone material or other materials with certain elasticity and capable of providing friction resistance.
