Description

[Technical field]

[0001] FIELD OF THE DISCLOSURE The embodiments of the present invention relate to the technical field of imaging devices, and in particular to imaging modules, cameras and electronic devices. [Background technology]

[0002] The aperture (variable aperture) is used to change the amount of light that enters the optical system and contributes to image formation. By providing an aperture to an imaging module, the imaging module can respond to shooting needs in scenes with different brightness by adjusting the size of the aperture, and the focus mechanism realizes focusing of the imaging module by changing the position of the lens assembly, allowing the imaging module to capture the subject more clearly. The combined use of the aperture and focus mechanism can improve the imaging module's shooting performance. As a result, many consumers are pleased to apply imaging modules equipped with aperture and focus mechanisms to electronic devices such as smartphones and tablets.

[0003] The blade drive device changes the size of the opening surrounded by the blades by moving a number of blades, and can be applied to different optical units in a camera, such as a shutter, an aperture, or a filter. In an optical system in which the lens is moved and adjusted by a lens drive device, the blade drive device may hinder the operation and arrangement of the lens drive device due to factors such as size, weight, and protrusion in multiple directions due to the assembly direction. By using a small blade drive mechanism made of shape memory metal, the problem of large weight and volume can be solved, but if it is necessary to have a large change in the size of the opening surrounded by the blades, the length of the shape memory metal must be increased. This still makes it impossible to effectively solve various problems caused by the large volume and weight of the blade drive mechanism.

[0004] In addition, it is necessary to avoid interference between the blade drive mechanism and the focus mechanism, which may affect the servo control of the focus mechanism. Or, when the lens is moved, the blade drive mechanism must move accordingly to block the light appropriately, so that the weight of the blade drive mechanism must be distributed evenly around the entire circumference. The above design scheme is difficult, and the reliability of the product manufactured by the above design scheme cannot be ensured.

[0005] Therefore, there is an urgent need in this field to develop an imaging module that can solve the above technical problems. Summary of the Invention [Problem to be solved by the invention]

However, in each embodiment of the present invention, many technical details are described to allow the reader to fully understand the present invention, but it is obvious to those skilled in the art that the technical solution protected by the present invention can be realized without these technical details and various changes and modifications based on the following embodiments.

Those skilled in the art can understand the specific meanings of the above terms in the present invention according to the specific circumstances.

[0024] Furthermore, the terms "first", "second", etc. are primarily used to distinguish between different devices, units or components (which may be of the same or different specific type and configuration) and are not intended to state or imply the relative importance or quantity of the designated devices, units or components. Unless otherwise specified, "plurality" means two or more.

[0025] As shown in FIGS. 1 to 7, one embodiment of the present invention relates to an imaging module 1000, which includes a lens assembly 100, a lens assembly support frame 200 fitted around the outer edge of the lens assembly 100, a base 300 fitted around the outside of the lens assembly support frame 200, a first driving member 310 provided on the base 300, and a drive member 310 provided on the lens assembly support frame 200 and facing the first driving member 310, thereby driving the lens assembly 100. The lens assembly 100 is supported by a second driving member 210 that drives the lens support frame 200 to move along the optical axis, a blade drive frame 400 that is movably supported by the base 300 and fitted to the outside of the lens assembly 100, a spherical support member 320 that is sandwiched between the blade drive frame 400 and the base 300, a blade support portion 110 that is provided at one end of the lens assembly 100 away from the base, and a blade support portion 110 that is provided on the blade drive frame 400 and rotates about the optical axis as a rotation axis. A blade drive ring 500 rotatably engaged with the blade support portion 110, and a plurality of light-shielding blades 600 positioned between the blade drive ring 500 and the blade support portion 110, the plurality of light-shielding blades 600 being provided at intervals on the blade drive ring 500 along the circumferential direction of the blade drive ring 500, and each of the plurality of light-shielding blades 600 is a light-shielding blade having one end rotatably connected to the blade support portion 110 and the other end slidably connected to the blade drive ring 500. 600, and a third driving member 410 provided on the blade drive frame 400 and facing the first driving member 310, the third driving member 410 interacting with the first driving member 310 to drive the blade drive frame 400 to rotate relative to the base 300 around the optical axis as a rotation axis, and the blade drive frame 400 drives the blade drive ring 500 to rotate, thereby bringing the multiple light-shielding blades 600 closer together or separating them.

[0026] Compared with the prior art, in the embodiment of the present invention, the base 300 is provided with a first driving member 310, the lens assembly support frame 200 is provided with the second driving member 210, the first driving member 310 cooperates with the second driving member 210 to drive the lens assembly support frame 200 to move along the optical axis for focusing, 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 around the optical axis as a rotation axis, and when the blade driving frame 400 rotates, the blade driving ring 500 is driven to rotate synchronously, and the blade driving ring 500 drives the plurality of light blocking blades 600 to approach or separate, thereby realizing adjustment of the size of the opening surrounded by the light blocking blades 600. In other words, the driving member for driving the plurality of light blocking blades 600 and the focus of the lens assembly 100 is the same first driving member 310. This reduces the number of parts of the imaging module 1000, reduces the volume and weight of the imaging module 1000, and avoids interference between the focusing mechanism in the imaging module 1000 and the power mechanism for driving the plurality of light blocking blades 600.

[0027] More specifically, the base 300, the blade drive frame 400, the blade support part 110, the plurality of shading blades 600 and the blade drive ring 500 are sequentially arranged from the image side to the object side of the imaging module 1000, that is, by sequentially arranging these parts along the optical axis, the imaging module 1000 can be assembled along the extension direction of the optical axis, thereby reducing the difficulty of assembly and avoiding protrusion in multiple directions.

[0028] The following provides a detailed description of the implementation of the imaging module of this embodiment. However, the following content is merely an implementation detail provided for ease of understanding and is not necessary for implementing this technical invention.

[0029] As can be understood, the lens assembly 100 includes a lens 120 and a barrel 130, the lens 120 is fixed to an inner wall of the barrel 130, and the barrel 130 is used to protect the lens 120 and prevent damage to the lens 120. In addition, the barrel 130 can provide a space to be connected to the lens assembly support frame 200, that is, the lens assembly support frame 200 is fitted and fixed to an outer wall of the barrel 130, and the blade support part 110 is provided on the object side of the barrel 130.

[0030] Referring also to FIG. 8, in this embodiment, there are at least three first accommodating grooves 330 extending in an arc shape on the side of the base 300 facing the blade drive frame 400, and there are at least three second accommodating grooves 420 extending in an arc shape on the side of the blade drive frame 400 facing the base 300, the first accommodating grooves 330 and the second accommodating grooves 420 are installed in a one-to-one correspondence and formed to surround an accommodating space, there are a plurality of the spherical support members 320, at least one spherical support member 320 is accommodated in each of the accommodating spaces, and the spherical support members 320 abut against the inner walls of the first accommodating grooves 330 and the second accommodating grooves 420 simultaneously. That is, when the first driving member 310 cooperates with the third driving member 410 to drive the blade driving frame 400 to rotate, the spherical support member 320 plays a role in supporting the blade driving frame 400 and can smoothly rotate the blade driving frame 400 by its own rolling. Selectively, the first accommodating grooves 330 and the second accommodating grooves 420 are each set to four, the first accommodating grooves 330 and the second accommodating grooves 420 are installed facing each other in a one-to-one relationship, the spherical support members 320 can also be set to four correspondingly, and at least one of the spherical support members 320 is accommodated in each of the accommodating spaces.

[0031] Specifically, the first receiving grooves 330 and the second receiving grooves 420 are both disposed at intervals around the optical axis. The first receiving grooves 330 may or may not be disposed on the same circular locus. Preferably, they are disposed on the same circular locus. The second receiving grooves 420 are disposed in the same manner, so there is no need to repeat the description here.

[0032] In another possible embodiment, the first accommodating grooves 330 and the second accommodating grooves 420 may each be set to three, the spherical support members 320 may also be set to three, and each of the accommodating spaces may accommodate one spherical support member 320. This ensures that the blade drive frame 400 rotates relative to the base 300 when a force is applied, while maintaining stability and preventing the blade drive frame 400 from flipping over. In addition, the number of spherical support members 320 may be reduced, further reducing the weight of the imaging module 1000.

[0033] In addition, the specific number and positions of the first accommodating grooves 330, the second accommodating grooves 420 and the spherical support members 320 can be set by those skilled in the art according to the actual force required, and the present invention does not particularly limit the same.

[0034] Furthermore, the first driving member 310 is a magnet 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 magnet steel moves the focusing coil along the optical axis, and drives the lens assembly support frame 200 to move along the optical axis for focusing. When the blade driving coil is energized, the magnet steel rotates the blade driving coil about the optical axis as a rotation axis, and drives the blade driving frame 400 to rotate about the optical axis as a rotation axis. Specifically, when energized, the focusing coil and the blade driving coil generate a Lorentz force between the magnet steel, and the Lorentz force drives the focusing coil and the blade driving coil to move. When focusing and blade movement are required, it is only necessary to energize, which increases the controllability of the imaging module.

[0035] In this embodiment, the focusing coil is provided in the circumferential direction surrounding the outer edge of the lens assembly support frame 200. In this embodiment, the lens assembly support frame 200 has a ring shape, the focusing coil is wound around the outer wall of the lens assembly support frame 200, and when electricity is applied to the focusing coil, a Lorentz force is generated between the focusing coil and the magnet steel, and since the magnet steel is fixed to the base 300, the focusing coil drives the lens assembly support frame 200 to move.

[0036] More specifically, there are a plurality of the magnet steels, which are spaced apart on the base 300 around the optical axis and are located on the side of the base 300 facing the lens assembly support frame 200.

[0037] Alternatively, in another possible embodiment, there are a plurality of focusing coils, and the plurality of focusing coils are installed at intervals on the lens assembly support frame 200 along the circumferential direction of the lens assembly support frame 200. For example, there are four focusing coils, and the four focusing coils are installed on the lens assembly support frame 200 at equal intervals around the outer periphery of the lens assembly support frame 200, and when the focusing coils are energized, all of the four focusing coils receive a force and drive the lens assembly support frame 200 to move. As can be understood, the focusing coils may be other numbers, for example, two, three, or more, and preferably, the plurality of focusing coils are installed on the lens assembly support frame 200 at equal intervals around the optical axis. This allows the lens assembly support frame 200 to receive a more balanced force, thereby improving the stability and reliability of the imaging module.

[0038] Furthermore, there are a plurality of the blade drive coils, and the plurality of the blade drive coils are installed at intervals on the blade drive frame 400 along the circumferential direction of the blade drive frame 400. Similarly, the number of the blade drive coils may be four, and the four blade drive coils are installed at intervals on the blade drive frame 400, and when the blade drive coils are energized, a Lorentz force is generated between the blade drive coils and the magnetic steel, and the four blade drive coils receive the force and drive the blade drive frame 400 to rotate about the optical axis as the rotation axis.

[0039] In addition, the lens assembly support frame 200 moves parallel to the optical axis due to the Lorentz force, but the blade drive frame 400 rotates around the optical axis as a rotation axis due to the Lorentz force. This is because the directions of the Lorentz forces received by the lens assembly support frame 200 and the blade drive frame 400 are different. The reason for this is that the arrangement methods of the focusing coil and the blade drive coil are different. Specifically, this can be determined and decided based on the left-hand rule.

[0040] Further, a first flexible circuit board 220 is provided on the lens assembly support frame 200, and a second flexible circuit board 430 is provided on the blade drive frame 400, and the first flexible circuit board 220 is electrically connected to the second flexible circuit board 430. Thus, when electricity is applied, electricity is applied to the first flexible circuit board 220 and the second flexible circuit board 430 simultaneously, thereby realizing synchronous adjustment of focus and aperture size.

[0041] 3 and 4 again, in this embodiment, in order to precisely control the focusing and iris adjustment of the imaging module, it is also necessary to detect the focusing movement amount of the lens assembly support frame 200 and the magnitude of the rotation amount of the blade driving frame 400. Specifically, a first position detection element 230 is provided on the lens assembly support frame 200, and a first sensing element 221 is electrically connected to the first flexible circuit board 220. When the lens assembly support frame 200 moves, the first sensing element 221 detects a change in the relative position of the first position detection element 230 to determine the focusing movement amount of the lens assembly support frame 200. For example, the first position detection element 230 may be a magnet, and the first sensing element 221 may be a Hall element, and when the lens assembly support frame 200 moves along the optical axis, the magnet moves following the lens assembly support frame 200, but the position of the Hall element is relatively fixed, and the magnetic field at the position of the Hall element changes constantly, which is mainly reflected in the magnetic flux passing through the Hall element changing constantly, thereby making it possible to detect the amount of movement of the lens assembly support frame 200.

[0042] In addition, a second sensing element 431 is electrically connected to the second flexible circuit board 430, and when the blade drive frame 400 rotates, the second sensing element 431 detects the relative position of the first driving member 310 to determine the rotation angle of the blade drive frame 400. For example, when the first driving member 310 is a magnetic member (i.e., magnet steel), the second sensing element 431 may be a Hall element, and when the first driving member 310 drives the blade drive frame 400 to rotate and moves the second sensing element 431, the second sensing element 431 detects a change in magnetic flux caused by the first driving member 310 at different positions to determine the rotation angle of the blade drive frame 400.

[0043] Further, the lens assembly support frame 200 is provided with a first leaf spring 240 and a second leaf spring 250, which are fixed to the object side surface and the image side surface of the lens assembly support frame 200, respectively, and at the same time, the first leaf spring 240 and the first leaf spring 350 are also fixed to the object side surface and the image side surface of the base 300, respectively. Thus, the lens assembly support frame 200 can be suspended and fixed to the base 300.

[0044] In this embodiment, when the lens assembly 100 is focused, in order to prevent the blade drive ring 500 from interfering with the lens assembly 100, the blade drive ring 500 needs to be movable along the optical axis. Specifically, the blade drive ring 500 is provided with a connection arm 510, the blade drive frame 400 is provided with a connection groove 440, and the connection arm 510 slidably enters the connection groove 440 along the optical axis to engage and connect the blade drive ring 500 and the blade drive frame 400. Specifically, the connection groove 440 penetrates the blade drive frame 400 along the optical axis direction, but engages and holds the connection arm 510 in a direction perpendicular to the optical axis, that is, the connection groove 440 is a through groove extending along the optical axis. As a result, when the blade driving frame 400 rotates, the blade driving ring 500 can be driven to rotate around the optical axis as a rotation axis, and the movement of the blade driving ring 500 in the extension direction of the optical axis is not affected. Since the blade driving ring 500 is fitted on the outside of the lens assembly 100, when the lens assembly 100 moves along the optical axis in a direction away from the base 300 by driving the lens assembly support frame 200, the outer edge of the lens barrel 130 moves the blade driving ring 500 in all directions. At this time, the connecting arm 510 slides in the connecting groove 440.

[0045] To be selective, there may be a plurality of the connection arms 510 and a plurality of the connection grooves 440, and the plurality of the connection arms 510 and the plurality of the connection grooves 440 may be engaged and connected in a one-to-one correspondence. Preferably, two of the connection arms 510 may be provided, one on each of the opposing sides of the blade drive ring 500, and two of the connection grooves 440 may be provided, one on each of the opposing sides of the blade drive frame 400. This makes it possible to increase the stability between the blade drive frame 400 and the blade drive ring 500 without increasing the difficulty of manufacturing the imaging module.

[0046] 9a to 9c, the blade drive ring 500 rotates by driving the blade drive frame 400 and drives the light blocking blades 600 to approach or separate, thereby adjusting the size of the aperture. Here, Fig. 9a is a diagram showing the state of the imaging module 1000 when the light blocking blades 600 approach each other to the limit position, Fig. 9b is a diagram showing the state of the imaging module 1000 in the process of the light blocking blades 600 separating, and Fig. 9c is a diagram showing the state of the imaging module 1000 when the light blocking blades 600 have separated to the limit position.

[0047] As can be understood, the blade support part 110, the blade drive ring 500 and the plurality of shading blades 600 together constitute a variable aperture, and when the blade drive ring 500 is driven to rotate, the blade drive ring 500 drives the plurality of shading blades 600 to move, thereby changing the aperture of the variable aperture, and thus adjusting the light beam that can pass through the variable 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 light blocking blades 600 to approach each other, so that the opening surrounded by the light blocking blades 600 becomes smaller, thereby reducing the amount of light entering the imaging module 1000, or the blade drive ring 500 drives the light blocking blades 600 to separate each other, so that the opening surrounded by the light blocking blades 600 becomes larger, thereby increasing the amount of light entering the imaging module 1000. In some cases, the blade drive frame 400 may rotate due to the effect of undesired movement or vibration, which may cause an unexpected change in the amount of light entering the imaging module. In order to avoid a similar situation, the imaging module in this embodiment further includes a blade holding member 450, which is fixed to the blade drive frame 400, and is used to hold the blade drive frame 400 in an initial position in a non-energized state in cooperation with the first drive member 310. As a result, when the blade drive coil is not energized, even if the blade drive frame 400 rotates due to unexpected vibration and the plurality of blades 600 move, the blade holding member 450 and the first drive member 310 cooperate with each other to return the blade drive frame 400 to its initial position, thereby stably holding the position of the plurality of light-shielding blades 600 and relatively stabilizing the size and shape of the opening surrounded by the plurality of light-shielding blades 600, and thus stably holding the amount of light entering the imaging module.

[0048] Specifically, the blade holding member 450 and the first driving member 310 are both magnetic members, and the first driving member 310 attracts the blade holding member 450 to maintain the angle of the blade drive frame 400 relative to the base 300. More specifically, in this embodiment, the first driving member 310 is a magnet steel, and the blade holding member 450 is a yoke, and the magnet steel attracts the yoke by magnetic force, thereby stably maintaining the position of the blade drive frame 400 relative to the base 300. When the blade drive frame 400 is rotated by an unexpected operation or vibration in a non-energized state, the blade drive frame 400 is automatically restored by the attractive force of the magnet steel and the yoke, and the plurality of light-shielding blades 600 are kept in a relatively stable position, and thus the size of the aperture is maintained. In addition, the effect of the unexpected operation or vibration on the blade drive frame 400 can be reduced by the action of the magnet steel and the yoke.

[0049] As can be understood, in this embodiment, the base 300 and the blade drive frame 400 realize relative fixation in the extending direction of the optical axis by the suction force between the first drive member 310 and the blade holding member 450. Specifically, the first drive member 310 attracts the blade holding member 450, and the blade holding member 450 is fixed to the blade drive frame 400, so that the blade drive frame 400 is driven by the blade holding member 450 and is fixed to the base 300. As can be seen from the above, a plurality of the spherical support members 320 are sandwiched 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. In addition, since the motion trajectory of the spherical support member 320 is restricted by the first accommodating groove 330 and the second accommodating groove 420, when the blade drive frame 400 is subjected to the Lorentz force between the first driving member 310 and the third driving member 410, the blade drive frame 400 can rotate relative to the base 300 with the optical axis as the rotation axis within a plane perpendicular to the optical axis.

[0050] The blade holding member 450 may be multiple and is installed at intervals around the blade drive frame 400 in the circumferential direction. This increases the attractive force between the magnetic steel and the yoke, and improves the stability of the position of the multiple light-shielding blades 600. Preferably, the length of the blade holding member 450 is 20% or more of the length of the first driving member 310. This increases the attractive force between each pair of the yoke and the magnetic steel, and improves the stability of the position of the multiple light-shielding blades 600. In addition, the magnitude of the attractive force can be changed by adjusting the length of the yoke, and thus the return ability of the aperture can be changed. More preferably, when the blade holding member 450 faces the first driving member 310, the connecting line between the geometric center of the blade holding member 450 and the geometric center of the first driving member 310 is parallel to the optical axis. This type of installation method of the yoke and the magnetic steel can utilize the effect of magnetic force more effectively than other installation methods.

[0051] Regarding the first driving member 310 and the blade holding member 450, using the magnetic force between them to fix the position of the blade drive frame 400 is the same as fixing it with a spring, so by adjusting the dimensions, shape, position and manufacturing material of the first driving member 310 and the blade holding member 450, the interactive force between the first driving member 310 and the blade holding member 450 can be adjusted, which is similar to changing the positional stability of the blade drive frame 400 by adjusting the elastic coefficient of a spring.

[0052] To be understood. In this embodiment, in order to reduce the manufacturing difficulty and the testing difficulty of the imaging module 1000, the magnet steel used in the first driving member 310 may be magnet steel having the same specifications, such as size, shape, material, etc. When the second driving member 210 is multiple, the focusing coils used in the second driving member 210 may be coils of the same specifications. The blade driving coils used in the third driving member 410 may be coils of the same specifications. The yokes used in the blade holding member 450 may be yokes of the same specifications. In some cases, if it is necessary to use different magnet steels in the first driving member 310, the specifications, number, and position arrangement can be adjusted by those skilled in the art according to the situation where force is received. The second driving member 210, the third driving member 410, and the blade holding member 450 are the same, so there is no need to repeat the description here.

[0053] Furthermore, in order to enhance the positional stability of the first driving member 310, the base 300 may be provided with a groove whose number and shape correspond to the first driving member 310, and the first driving member 310 may be provided in one-to-one correspondence with the groove, and the first driving member 310 may be limited and fixed by using the inner wall of the groove. In the case of the second driving member 210, when the second driving member 210 is a focusing coil provided to surround the outer periphery of the lens assembly support frame 200, a groove extending in the circumferential direction may be provided on the outer edge of the lens assembly support frame 200, and the second driving member 210 may be provided in the groove extending in the circumferential direction. When the second driving member 210 is a plurality of focusing coils provided at intervals, the lens assembly support frame 200 may be provided with a groove whose number and shape correspond to the plurality of focusing coils, and the second driving member 210 may be provided in one-to-one correspondence with the groove, and the second driving member 210 may be limited and fixed by using the inner wall of the groove. In the case of the third driving member 410, the blade driving frame 400 is provided with a groove whose number and contour correspond to the third driving member 410, and the third driving member 410 is provided in a one-to-one correspondence with the groove, and the third driving member 410 can be limited and fixed by using the inner wall of the groove. The blade holding member 450 can adopt the same arrangement as the third driving member 410. In addition, the dimension of the blade holding member 450 is generally smaller than that of the third driving member 410. Therefore, a groove for mounting the blade holding member 450 can be newly opened on the bottom wall of the groove for mounting the third driving member 410. In this way, the third driving member 410 can be used to limit the blade holding member 450 and prevent the front blade holding member 450 from coming off the blade driving frame 400 while satisfying the mounting needs of the third driving member 410 and the blade holding member 450.

[0054] In another possible embodiment, the yoke can be replaced by a magnetic fluid, the principles of which are the same as when using a yoke and need not be repeated here.

[0055] 10 to 12, in this 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 circumferential direction 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 extending direction of each of the through grooves 520 forms an angle with the radial direction of the blade drive ring 500. Each of the plurality of light-shielding blades 600 has an arc-shaped sheet shape, and one end of each of the plurality of light-shielding blades 600 is provided with a guide portion 610, which is located on the object side surface of the light-shielding blade 600, and the guide portions 610 of the plurality of light-shielding blades 600 correspond to the through grooves 520 one-to-one and are slidably inserted therein. As a result, when the blade drive ring 500 rotates, the guide portion 610 is restricted by the inner wall of the through groove 520 and slides along the through groove 520, causing the size and shape of the opening surrounded by the multiple light-shielding blades 600 to change, thereby changing the amount of light entering the imaging module.

[0056] Further, a stopper portion 521 is provided on the inner wall of each of the through grooves 520 at a position close to the optical axis, and the stopper portion 521 is used to limit the movement range of the guide portion 610. In practice, the stopper portion 521 can reduce the dimension of the through groove 520 at a position close to the optical axis, and when the guide portion 610 moves to the stopper portion 521, it is blocked by the stopper portion 521, and the guide portion 610 does not leave the through groove 520. Furthermore, the stopper portion 521 can also be provided at a position away from the optical axis of the through groove 520 so that the guide portion 610 can only slide within the through groove 520.

[0057] Optionally, the guide portion 610 may be a protrusion protruding from the surface of the light-shielding blade 600, and the specific shape and size of the protrusion may be set according to actual circumstances. Considering the effect of resistance, the guide portion 610 is preferably a cylindrical structure. If there are other special needs, the guide portion 610 may be suitably adjusted to have other shapes.

[0058] 13, in this embodiment, a plurality of positioning holes 111 are provided at intervals along the circumferential direction of the blade support part 110, and the other ends of the plurality of light-shielding blades 600 are all provided with positioning parts 620, which are located on the image side surface of the light-shielding blade 600, and the positioning parts 620 of the plurality of light-shielding blades 600 correspond one-to-one to the positioning holes 111 and are rotatably inserted therein. That is, the positioning parts 620 are provided on the image side surface of each of the light-shielding blades 600, and the positioning parts 620 are rotatably inserted into the positioning holes 111, and when the blade drive ring 500 rotates, the inner wall of the through groove 520 biases the guide part 610 to drive the plurality of light-shielding blades 600 to move. The other ends of the plurality of light-shielding blades 600 are restricted to the blade support part 110 via the positioning parts 620, but are still rotatable. As a result, the plurality of light-shielding blades 600 rotate around the axis of the corresponding positioning hole 111 as a rotation axis, and move closer to or apart from each other, thereby achieving a change in the size of the aperture.

[0059] In this embodiment, the blade drive ring 500 is annular, the plurality of shading blades 600 are each in the shape of an arc sheet, and the length of the shading blade is 30% to 60% of the circumference of the blade drive ring, so that the shading blades 600 have a sufficient length while maintaining a light weight, and can avoid mutual interference between the different shading blades 600 during their movements. In this embodiment, the multiple light shielding blades 600 are stacked in order and surrounded as a ring, specifically, the guide portion 610 of the first light shielding blade 600 fits into one of the through grooves 520, the positioning portion 620 at the other end fits into the positioning hole 111, the object side surface of one end where the guide portion 610 of the second light shielding blade 600 is provided is in close contact with the image side surface of one end where the positioning portion 620 of the first light shielding blade 600 is provided, and the guide portion 610 of the second light shielding blade 600 fits into another through groove 520, and the positioning portion 620 of the second light shielding blade 600 fits into another positioning hole 111. By this analogy, all the light shielding blades 600 are formed to surround one ring.

[0060] Furthermore, the orthogonal projection area of ​​the light-shielding vanes 600 on a plane perpendicular to the optical axis is defined as a first area, and the orthogonal projection area of ​​the sector of the light-shielding vanes 600 whose edge away from the optical axis is an arc on a plane perpendicular to the optical axis is defined as a second area, and the first area is 40% to 70% of the second area. This makes the weight of the multiple light-shielding vanes 600 light, and also makes it possible to avoid interference between different light-shielding vanes 600.

[0061] The number of the light blocking blades 600 can be adjusted according to actual needs. Generally, the more the number of the light blocking blades 600, the closer the opening surrounded by the light blocking blades 600 is to a circle. In consideration of the weight and manufacturing cost of the imaging module, the number of the light blocking blades 600 can be set to 5 to 7.

[0062] 6 and 7 again, in this embodiment, the blade support part 110 is groove-shaped, and the groove opening of the blade support part 110 is spaced from the base 300. A driving ring platen 112 is fixedly installed on an edge of the blade support part 110 surrounding the groove opening. The driving ring platen 112, the blade driving ring 500 and the blade support part 110 form a blade chamber 113 surrounding the blade chamber 113. The light-shielding blades 600 are located within the blade chamber 113. The driving ring platen 112 is used to limit the position of the blade driving ring 500 in the optical axis direction and prevent the blade driving ring 500 and the lens assembly 100 from interfering with each other to hinder the rotation of the blade driving ring 500.

[0063] 3 to 5 again, in this embodiment, the focus mechanism 30 of the imaging module 1000 may include a first driving member 310, the second driving member 210, and the lens assembly support frame 200, and the blade driving mechanism 40 of the imaging module 1000 may include a first driving member 310, a third driving member 410, the blade driving frame 400, the blade driving ring 500, and the blade support part 110. Here, the driving sources of the focus mechanism 30 and the blade driving mechanism 40 are both the first driving member 310.

[0064] In this embodiment, the imaging module 1000 further includes a housing 700 having an accommodating space, in which the base 300, the lens assembly support frame 200 and the blade drive frame 400 are located. The housing 700 has a first central through hole 710, which is used to expose the blade drive ring 500, the light blocking blades 600 and the blade support part 110. The housing 700 is made of a magnetic material, which can confine the focusing coil, the blade drive coil and the magnet steel in a closed magnetic circuit to enhance the overall magnetism.

[0065] Another embodiment of the present invention relates to an imaging module 1000, and as shown in Figures 14 to 17, the imaging module 1000 in this embodiment is almost the same as the above-mentioned embodiments, but the main difference is that the imaging module 1000 in this embodiment further includes an image stabilization mechanism 800 and a sensor assembly 810 provided in the image stabilization mechanism 800, the image stabilization mechanism 800 is located on the image side of the base 300, and the image stabilization mechanism 800 is used to drive the sensor assembly 810 to achieve image stabilization.

[0066] Compared with the above-mentioned embodiment, in this embodiment, in addition to realizing focusing in the optical axis direction and realizing aperture adjustment by the plurality of light-shielding blades 600, the image stabilization mechanism 800 can be used to stabilize the sensor assembly 810 in a direction perpendicular to the optical axis, thereby improving the shooting effect of the imaging module 1000. In addition, since the driving of the image stabilization mechanism 800 with respect to the sensor assembly 810 and the driving of the first driving member 310 with respect to the lens assembly 100 are independent of each other, changes due to the driving of the first driving member 310 with respect to the focusing and aperture do not affect the driving of the image stabilization mechanism 800 with respect to the image stabilization. In other words, the image stabilization of the image stabilization mechanism 800 with respect to the sensor assembly 810 does not affect the driving of the first driving member 310. As a result, in the performance evaluation of the imaging module 1000, the performance of each of the focus mechanism, the blade driving mechanism, and the image stabilization mechanism 800 can be tested independently, thereby reducing the difficulty of testing the imaging module. The imaging module of the present invention has a simplified structure, which increases reliability, and at the same time, improves the layout of parts, thereby reducing the failure rate.

[0067] 17 again, specifically, the imaging module 1000 further includes a bottom case 720, which, together with the housing 700, surrounds and fixes the lens assembly 100, a focus mechanism, a blade driving mechanism, and an image stabilization mechanism 800. Preferably, the bottom case 720 may be made of a magnetic material.

[0068] In this embodiment, the image stabilization mechanism 800 includes an image stabilization base 820 and a movable holder 830, the movable holder 830 is located on the object side of the image stabilization base 820 and is movable in a direction perpendicular to the optical axis relative to the image stabilization base 820, and the sensor assembly 810 is fixed to the movable holder 830. Thereby, the sensor assembly 810 is driven to move by moving the movable holder 830, thereby realizing the image stabilization function of the imaging module 1000.

[0069] Specifically, the image stabilization base 820 is provided with a plurality of image stabilization magnet steels 821 arranged at intervals around the optical axis, the movable holder 830 is provided with a plurality of fixing yokes 831 arranged at intervals around the optical axis, at least three balls 833 are sandwiched between the image stabilization base 820 and the movable holder 830, and the image stabilization magnet steels 821 and the fixing yokes 831 attract each other, bringing the image stabilization base 820 and the movable holder 830 closer to each other and clamping all of the balls 833. Since the balls 833 are spherical, the movable holder 830 is movable relative to the image stabilization base 820 when the balls 833 roll.

[0070] More specifically, the image stabilization base 820 is provided with a plurality of first storage grooves 822, the movable holder 830 is provided with a plurality of second storage grooves (not shown), the plurality of balls 833 correspond one-to-one to the plurality of first storage grooves 822 and are located within the first storage groove 822, and the plurality of second storage grooves correspond one-to-one to the plurality of first storage grooves 822. By storing the ball 833 using a storage groove, the motion range of the ball 833 can be limited, the ball 833 can be prevented from falling off, and the stability of the imaging module 1000 can be increased.

[0071] In this embodiment, a first spacer 822a is provided in each of the first receiving grooves 822, and a second spacer 832a is provided in each of the second receiving grooves 822. The first spacer 822a and the second spacer 832a are both used to support the balls 833.

[0072] In this embodiment, the image stabilization mechanism 800 includes a coil holder 840 fixed to the movable holder 830, and the coil holder 840 is provided with a plurality of image stabilization coils (not shown) that are arranged at intervals around the optical axis, and the plurality of image stabilization coils are arranged in one-to-one correspondence and facing the plurality of image stabilization magnet steels 821. When energized, the image stabilization coil generates a Lorentz magnetic force between the image stabilization magnet steel 822 and the coil holder 840 to move in a direction perpendicular to the optical axis, driving the movable holder 830 to move synchronously, and when the movable holder 830 moves, the sensor assembly 810 moves following the movable holder 830, thereby achieving image stabilization of the imaging module 1000.

[0073] That is, the image stabilization base 820 and the movable holder 830 are relatively fixed in the extending direction of the optical axis by the attractive force between the image stabilization magnet steel 821 and the fixing yoke 831, and the ball 833 can roll in the first receiving groove 822 and the receiving groove, i.e., the ball 833 can roll relative to the image stabilization base 820 and the movable holder 830, and when the movable holder 830 is subjected to the Lorentz force between the image stabilization magnet steel 821 and the image stabilization coil, the movable holder 830 moves relative to the image stabilization base 820 in a plane perpendicular to the optical axis. This allows the sensor assembly 810 to move in a plane perpendicular to the optical axis, thereby achieving image stabilization.

[0074] Specifically, in this embodiment, the imaging module 1000 supplies power to the multiple image stabilization coils through a circuit board 850 .

[0075] In this embodiment, a mounting hole 823 is provided in the image stabilization base 820, a damping member 823a is provided in the mounting hole 823, and the damping member 823a penetrates the mounting hole 823 and contacts the bottom case 720 and the sensor assembly 810, respectively, and more specifically, the bottom case 720 and the sensor assembly 810 sandwich the damping member 823a to slightly deform the damping member 823a. As a result, the damping member 823a provides resistance when the sensor assembly 810 moves, slowing down the movement speed of the sensor assembly 810 and preventing excessive vibration caused by too fast movement of the sensor assembly 810 during image stabilization.

[0076] For example, in this embodiment, the number of the mounting holes 823 and the damping members 823a is four, and they are all spaced apart around the optical axis. Here, the damping members 823a are made of rubber. As can be appreciated, the number of the mounting holes 823 and the damping members 823a can be set to other numbers, and the damping members 823a can be made of silica gel material or other materials that have a certain elasticity and can provide friction resistance.

[0077] In another embodiment of the present invention, there is provided a camera comprising a camera body and an imaging module as in either one of the two embodiments above, the imaging module being mounted on the camera body.

[0078] In another embodiment of the present invention, there is provided an electronic device comprising a device body and an imaging module such as one of the two embodiments described above, the imaging module being mounted on the device body.

[0079] As can be understood, the electronic device in this embodiment may be a mobile device such as a smartphone, a tablet, a laptop, or a smartwatch.

[0080] Although the imaging module, camera, and electronic device according to the embodiment of the present invention have been described in detail above, and the principles and embodiments of the present invention have been described using specific examples in this specification, the description of the above embodiments is only intended to aid in understanding the concept of the present invention, and the embodiments and scope of application may be changed. For the above reasons, the contents of this specification should not be understood as limiting the present invention.
