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]

[0020] In order to clarify the purpose, technical ideas and advantages of the embodiments of the present invention, the following detailed description of each embodiment of the present invention will be given with reference to the drawings. 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.

[0022] In addition, some of the above terms can be used to express other meanings in addition to expressing an orientation or positional relationship. For example, the term "up" can also be used to express a dependency or connection relationship in some cases. Those skilled in the art can understand the specific meanings of these terms in the present invention according to specific situations.

[0023] Furthermore, the terms "attach", "install", "installed", "established", "connected" and "connected" should be understood in a broad sense. For example, they may be fixed connections, removable connections, or integral structures, mechanical connections, or electrical connections, and may be direct connections, indirect connections through intermediate media, or internal communication between two devices, units or components. 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 5, one embodiment of the present invention relates to an imaging module 1000, which includes a lens assembly 100, a base 200 provided with a driving member 210, a lens assembly support frame 300 fitted to the outer edge of the lens assembly 100, the driving member 200 driving the lens assembly support frame 300 to move for focusing along an optical axis, a blade drive frame 400 rotatably provided on the base 200 with the optical axis as a rotation axis and fitted to the outside of the lens assembly 100, the blade drive frame 400 being also used to drive the driving member 210 to rotate the blade drive frame 400, and a blade drive ring rotatably provided on the blade drive frame 400 and fitted to the outside of the lens assembly 100 with the optical axis as a rotation axis. the blade drive ring 500 that drives the blade drive frame 400 to rotate when the blade drive frame 400 rotates by being driven by the driving member 210; a plurality of light blocking vanes 600 that are spaced apart from one another on the blade drive ring 500 along the circumferential direction of the blade drive ring 500, the light blocking vanes 600 moving closer to or apart from one another when the blade drive ring 500 rotates; and a blade support member 700 that is engaged and fixed to the object side of the lens assembly support frame 300, the light blocking vanes 600 being positioned between the blade drive ring 500 and the blade support member 700, the light blocking vanes 600 being all rotatably connected to the blade support member 700, and the blade support member 700 being used to support the light blocking vanes 600.

[0026] Compared with the prior art, in the embodiment of the present invention, the base 200 is provided with the driving member 210, which is used to drive the lens assembly support frame 300 to move along the optical axis for focusing, and the driving member 210 is also used 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, it drives the blade driving ring 500 to rotate synchronously, and the blade driving ring 500 drives the plurality of light-shielding blades 600 to move closer to or apart from each other, thereby realizing the adjustment of the size of the opening surrounded by the plurality of light-shielding blades 600. In other words, the plurality of light-shielding blades 600 and the driving member 210 for driving the focus of the lens assembly 100 are the same. This reduces the number of parts of the imaging module 1000, reduces the volume and weight of the imaging module 1000, and prevents interference between the focusing mechanism in the imaging module 1000 and the power mechanism that drives the light-shielding blades 600.

[0027] 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.

[0028] In this embodiment, the base 200, the blade drive frame 400, the blade drive ring 500, the multiple light-shielding blades 600 and the blade support member 700 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.

[0029] As can be understood, the lens assembly 100 includes a lens 110 and a barrel 120, where the lens 110 is fixed to an inner wall of the barrel 120, and the barrel 120 is used to protect the lens 110 and prevent damage to the lens 110. In addition, the barrel 120 can provide a space for connection with the lens assembly support frame 300, that is, the lens assembly support frame 300 is fitted and fixed to the outer wall of the barrel 120.

[0030] 6, in this embodiment, the base 200 has at least three first accommodating grooves 220 extending in an arc shape on the side facing the blade drive frame 400, and the blade drive frame 400 has at least three second accommodating grooves 410 extending in an arc shape on the side facing the base 200, and the first accommodating grooves 220 and the second accommodating grooves 410 are installed in a one-to-one correspondence and formed to surround an accommodating space, and each accommodating space has a spherical support member 230, which simultaneously abuts against the inner walls of the first accommodating groove 220 and the second accommodating groove 410. In other words, when the driving member 410 drives the blade drive frame 400 to rotate, the spherical support member 230 plays a role of supporting the blade drive frame 400, and can smoothly rotate the blade drive frame 400 by its own rolling. As an option, the first accommodating grooves 220 and the second accommodating grooves 410 are each set to four, and the first accommodating grooves 220 and the second accommodating grooves 410 are installed opposite each other in a one-to-one relationship, and the spherical support members 230 can also be correspondingly set to four.

[0031] Specifically, the first receiving grooves 220 and the second receiving grooves 410 are disposed at intervals around the optical axis. The first receiving grooves 220 may or may not be disposed on the same circular locus. Preferably, they are disposed on the same circular locus. The second receiving grooves 410 are disposed in the same manner as the first receiving grooves 220.

[0032] In another possible embodiment, the first accommodating grooves 220 and the second accommodating grooves 410 may each be set to three, the spherical support members 230 may also be set to three, and each of the accommodating spaces may accommodate one spherical support member 230. This ensures that the blade drive frame 400 rotates relative to the base 200 when a force is applied, while maintaining stability and preventing the blade drive frame 400 from reversing in the extension direction of the optical axis. In addition, the number of the spherical support members 230 may be reduced, and the weight of the imaging module 1000 may be further reduced.

[0033] In addition, the specific number and positions of the first receiving groove 220, the second receiving groove 410 and the spherical support members 230, and the number of the spherical support members 230 provided in one receiving groove can be set by those skilled in the art according to the teachings of the present invention according to the actual demands of the force they will receive. These all belong to the concept of the present invention, and the present invention does not particularly limit them.

[0034] In this embodiment, the lens assembly support frame 300 is provided with a first driven member 310, and the driving member 210 drives the first driven member 310 to move, thereby driving the lens assembly support frame 300 to move for focusing along the optical axis, and the blade drive frame 400 is provided with a second driven member 420, and the driving member 210 drives the second driven member 420 to rotate, thereby driving the blade drive frame 400 to rotate. In other words, the focusing movement of the lens assembly 100 is performed by the driving member 210 biasing the first driven member 310 and the first driven member 310 being fixed to the lens assembly support frame 300, so that the lens assembly support frame 300 is driven and moves, and the lens assembly 100 is fixed to the lens assembly support frame 300, so that the lens assembly 100 also follows the movement of the lens assembly support frame 300 to achieve focusing. Meanwhile, the driving member 210 biases the second driven member 420, and the blade driving frame 400 rotates around the optical axis as a rotation axis, so that the forces received by the first driven member 310 and the second driven member 420 do not interfere with each other, thereby avoiding mutual influence between the focusing movement and the blade movement.

[0035] Furthermore, the driving member 210 is a magnet steel, the first driven member 310 is a focusing coil, and the second driven member 420 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 300 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 1000.

[0036] In this embodiment, the focusing coil is provided in the circumferential direction surrounding the outer edge of the lens assembly support frame 300. In this embodiment, the lens assembly support frame 300 is ring-shaped, the focusing coil is wound around the outer wall of the lens assembly support frame 300, 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 200, the focusing coil drives the lens assembly support frame 300 to move.

[0037] More specifically, there are a plurality of the magnet steels, which are spaced apart on the base 200 around the optical axis and are located on the side of the base 200 facing the lens assembly support frame 300.

[0038] Alternatively, in another possible embodiment, there are a plurality of focusing coils, and the plurality of focusing coils are disposed at intervals on the lens assembly support frame 300 along the circumferential direction of the lens assembly support frame 300. For example, there are four focusing coils, and the four focusing coils are disposed at equal intervals on the lens assembly support frame 300 around the outer periphery of the lens assembly support frame 300, and when the focusing coils are energized, all of the four focusing coils receive a force to drive the lens assembly support frame 300 to move. As can be understood, the number of focusing coils may be other numbers, for example, two, three, or more, and preferably, the plurality of focusing coils are disposed at equal intervals on the lens assembly support frame 300 around the optical axis. This makes the force received by the lens assembly support frame 300 more balanced, thereby improving the stability and reliability of the imaging module.

[0039] 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.

[0040] The lens assembly support frame 300 moves parallel to the optical axis due to the Lorentz force, while 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 300 and the blade drive frame 400 are different. This is because 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.

[0041] Further, a first flexible circuit board 320 is provided on the lens assembly support frame 300, and a second flexible circuit board 430 is provided on the blade drive frame 400, and the first flexible circuit board 320 is electrically connected to the second flexible circuit board 430. Thus, when electricity is applied, electricity is applied to the first flexible circuit board 320 and the second flexible circuit board 430 simultaneously, thereby realizing synchronous adjustment of focus and aperture size.

[0042] 3 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 300 and the magnitude of the rotation amount of the blade drive frame 400. Specifically, a first position detection element 330 is provided on the lens assembly support frame 300, and a first sensing element 321 is electrically connected to the first flexible circuit board 320. When the lens assembly support frame 300 moves, the first sensing element 321 detects a change in the relative position of the first position detection element 330 to determine the focusing movement amount of the lens assembly support frame 300. For example, the first position detection element 330 may be a magnet, and the first sensing element 321 may be a Hall element, and when the lens assembly support frame 300 moves along the optical axis, the magnet moves following the lens assembly support frame 300, 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 300.

[0043] Further, a second sensing element 431 is electrically connected to the second flexible circuit board 430, and when the blade driving frame 400 rotates, the second sensing element 431 detects the relative position of the driving member 210 to determine the rotation angle of the blade driving frame 400. For example, if the driving member 210 is a magnetic member (i.e., magnet steel), the second sensing element 431 may be a Hall element, and when the driving member 210 drives the blade driving 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 driving member 210 at different positions to determine the rotation angle of the blade driving frame 400.

[0044] Further, the lens assembly support frame 300 is provided with a first leaf spring 340 and a second leaf spring 350, which are fixed to the object side surface and the image side surface of the lens assembly support frame 300, respectively, and at the same time, the first leaf spring 340 and the first leaf spring 350 are also fixed to the object side surface and the image side surface of the base 200, respectively. Thus, the lens assembly support frame 300 can be suspended and fixed to the base 200.

[0045] 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 in a direction away from the base 200 along the optical axis by driving the lens assembly support frame 300, the outer edge of the lens barrel 120 moves the blade driving ring 500 in all directions. At this time, the connection arm 510 slides in the connection groove 440.

[0046] 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.

[0047] 7a to 7c, 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. 7a is a diagram showing a state when the light blocking blades 600 of the imaging module 1000 approach each other to the limit position, Fig. 7b is a diagram showing a state in which the light blocking blades 600 of the imaging module 1000 are in the process of separating, and Fig. 7c is a diagram showing a state when the light blocking blades 600 of the imaging module 1000 have separated to the limit position.

[0048] As can be understood, the blade drive ring 500, the plurality of light-shielding blades 600 and the blade support member 700 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 light-shielding 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 undesired movement or vibration, which may cause an unexpected change in the amount of light entering the imaging module 1000. In order to avoid a similar situation, the imaging module 1000 in this embodiment further includes a blade holding member 450, which is fixed to the blade drive frame 400, and is used to maintain the blade drive frame 400 at its initial position in a non-energized state in cooperation with the drive member 210. 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 moves, the blade holding member 450 and the drive member 210 cooperate with each other to maintain the blade drive frame 400 at its initial position, thereby stably maintaining 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, thereby stably maintaining the amount of light entering the imaging module 1000.

[0049] Specifically, both the blade holding member 450 and the driving member 210 are magnetic members, and the driving member 210 attracts the blade holding member 450 to maintain the angle of the blade drive frame 400 relative to the base 200. More specifically, in this embodiment, the driving member 210 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 200. If the blade drive frame 400 is rotated by unexpected operation or vibration in a non-energized state, the blade drive frame 400 automatically returns to its original position due to the attractive force of the magnet steel and the yoke, and the plurality of light-shielding blades 600 are maintained in a relatively stable position, thereby maintaining the size of the aperture.

[0050] As can be understood, in this embodiment, the base 200 and the blade drive frame 400 realize relative fixation in the extending direction of the optical axis by the suction force between the driving member 210 and the blade holding member 450. Specifically, the driving member 210 attracts the blade holding member 450, and since the blade holding member 450 is fixed to the blade drive frame 400, the blade drive frame 400 is driven by the blade holding member 450 and is fixed to the base 200. As can be seen from the above, a plurality of the spherical support members 230 are sandwiched between the base 200 and the blade drive frame 400, and the spherical support members 230 can roll relative to the base 200 and the blade drive frame 400. In addition, since the motion trajectory of the spherical support member 230 is restricted by the first accommodating groove 220 and the second accommodating groove 410, when the blade drive frame 400 is subjected to the Lorentz force between the driving member 210 and the second driven member 420, the blade drive frame 400 can rotate relative to the base 200 with the optical axis as the rotation axis within a plane perpendicular to the optical axis.

[0051] 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 drive member 210. This increases the attractive force between each pair of yokes and 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 drive member 210, the connecting line between the geometric center of the blade holding member 450 and the geometric center of the drive member 210 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.

[0052] Regarding the driving member 210 and the blade holding member 450, using the magnetic force between them to fix the position of the blade drive frame 400 has the same effect as fixing it with an elastic member (e.g., a spring). Therefore, by adjusting the dimensions, shape, position and material of the driving member 210 and the blade holding member 450, the interactive force between the driving member 210 and the blade holding member 450 can be adjusted, which is similar to changing the return ability of the blade drive frame 400 to vibration or hand shake by adjusting the elastic modulus of an elastic member.

[0053] 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 driving member 210 may be magnet steel having the same specifications, such as size, shape, material, etc. When the first driven member 310 is multiple, the focusing coil used in the first driven member 310 may be a coil having the same specifications. The blade driving coil used in the second driven member 420 may be a coil having the same specifications, and when the first driven member 310 is multiple, the first driven member 310 and the second driven member 420 may be coils having the same specifications. The yoke used in the blade holding member 450 may be a yoke having the same specifications. In some cases, when it is necessary to use different magnet steels for the driving member 210, the specifications, number, and position arrangement can be adjusted by a person skilled in the art according to the situation where the force is received. The first driven member 310, the second driven member 420, and the blade holding member 450 are the same, so there is no need to repeat the description here.

[0054] Furthermore, in order to enhance the positional stability of the driving members 210, the base 200 may be provided with grooves whose number and contours correspond to the driving members 210, and the driving members 210 may be provided in a one-to-one correspondence with the grooves, and the driving members 210 may be limited and fixed by using the inner walls of the grooves, and the connection strength between the driving members 210 and the base 200 may be enhanced by an adhesive connection manner. In the case of the first driven member 310, when the first driven member 310 is a focusing coil provided to surround the outer periphery of the lens assembly support frame 300, a groove extending in the circumferential direction may be provided on the outer edge of the lens assembly support frame 300, and the first driven member 310 may be provided in the groove extending in the circumferential direction. When the first driven member 310 is a plurality of focusing coils arranged at intervals on the lens assembly support frame 300 surrounding the optical axis, the lens assembly support frame 300 may be provided with a plurality of grooves whose number and contour correspond to the plurality of focusing coils, and the first driven member 310 may be provided in one-to-one correspondence with the grooves, and the first driven member 310 may be limited and fixed by using the inner wall of the groove. In the case of the second driven member 420, the blade drive frame 400 may be provided with grooves whose number and contour correspond to the second driven member 420, and the second driven member 420 may be provided in one-to-one correspondence with the grooves, and the second driven member 420 may be limited and fixed by using the inner wall of the groove. The blade holding member 450 may adopt the same arrangement as the second driven member 420. In addition, the size of the blade holding member 450 is generally smaller than that of the second driven member 420. Therefore, another groove for mounting the blade holding member 450 can be provided on the inner wall of the groove for mounting the second driven member 420. As a result, the mounting needs of the second driven member 420 and the blade holding member 450 can be met, and the blade holding member 450 can be limited by using the second driven member 420 to prevent the front blade holding member 450 from coming off the blade drive frame 400.

[0055] 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.

[0056] 8 to 10, 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 a guide portion 610 is provided at one end of each of the plurality of light-shielding blades 600, and the guide portion 610 is located on the image side surface of the light-shielding blade 600, and the guide portion 610 of each of the plurality of light-shielding blades 600 corresponds to the through grooves 520 one-to-one and is 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 moves so as to slide along the through groove 520, causing the size and shape of the opening surrounded by the multiple light-shielding blades 600 to change, and ultimately changing the amount of light entering the imaging module 1000.

[0057] 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.

[0058] 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. In other possible embodiments, the guide portion 610 may be suitably adjusted to have other shapes.

[0059] 11, in this embodiment, a plurality of positioning holes 710 are provided at intervals along the circumferential direction of the blade support member 700, and the other ends of the plurality of light-shielding blades 600 are all provided with positioning portions 620, which are located on the object side surface of the light-shielding blades 600, and the positioning portions 620 of the plurality of light-shielding blades 600 correspond one-to-one to the positioning holes 710 and are rotatably inserted therein. That is, the positioning portions 620 are provided on the object side surface of each of the light-shielding blades 600, and the positioning portions 620 are rotatably inserted into the positioning holes 710, and when the blade drive ring 500 rotates, the inner wall of the through groove 520 biases the guide portion 610 to drive the light-shielding blades 600 to move. The other ends of the light-shielding blades 600 are restricted to the blade support member 700 via the positioning portions 620, but are still rotatable. As a result, the plurality of light-shielding blades 600 rotate around the axis of the corresponding positioning hole 710 as a rotation axis, and move closer to or apart from each other, thereby achieving a change in the size of the aperture.

[0060] In this embodiment, the blade driving ring 500 is annular, the light-shielding blades 600 are arc-shaped sheets, and the length of the light-shielding blades is 30% to 60% of the circumference of the blade driving ring, so that the light-shielding blades 600 have a sufficient length while maintaining a light weight, and can avoid mutual interference between different light-shielding 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 710, 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 710 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 710. By this analogy, all the light shielding blades 600 are formed to surround one ring.

[0061] 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.

[0062] 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.

[0063] 4 and 5, in this embodiment, the blade support member 700 is groove-shaped with a first central through-hole 720, the opening of the groove of the blade support member 700 faces the lens assembly support frame 300, and a driving ring platen 730 is fixedly installed on an edge of the blade support member 700 surrounding the groove opening, the driving ring platen 730 and the blade support member 700 form a blade chamber 740, and the blade drive ring 500 and the plurality of light-shielding blades 600 are both located within the blade chamber 740, and the driving ring platen 730 is used to limit the position of the blade drive ring 500 in the optical axis direction and prevent the blade drive ring 500 and the lens assembly 100 from interfering with each other to hinder the rotation of the blade drive ring 500.

[0064] In this embodiment, the driving member 210, the first driven member 310 and the lens assembly support frame 300 may constitute a focus mechanism, and the driving member 210, the second driven member 420, the blade drive frame 400, the blade drive ring 500 and the blade support member 700 may constitute a blade drive mechanism, in which the driving source of both the focus mechanism and the blade drive mechanism is the driving member 210.

[0065] In this embodiment, the imaging module 1000 further includes a housing 800 having an accommodation space, in which the base 200, the lens assembly support frame 300 and the blade drive frame 400 are located. The housing 800 has a second central through hole 810, which is used to expose the blade drive ring 500, the light blocking blades 600 and the blade support member 700. The housing 800 is made of a magnetic material, and can confine the focusing coil, the blade drive coil and the magnet steel in a closed magnetic circuit to enhance the overall magnetism.

[0066] Another embodiment of the present invention relates to an imaging module 1000. As shown in FIG. 12, the imaging module 1000 in this embodiment is almost the same as the above-mentioned embodiment, but the main difference is that the imaging module 1000 in this embodiment further includes an image stabilization mechanism 900 and a sensor assembly 910 provided in the image stabilization mechanism 900, the image stabilization mechanism 900 is located on the image side of the base 200, and the image stabilization mechanism 900 is used to drive the sensor assembly 910 to realize image stabilization.

[0067] 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 900 can be used to stabilize the sensor assembly 910 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 900 with respect to the sensor assembly 910 and the driving of the driving member 210 with respect to the lens assembly 100 are independent of each other, changes due to the driving of the driving member 210 with respect to the focusing and aperture do not affect the driving of the image stabilization mechanism 900 with respect to the image stabilization. In other words, the image stabilization of the image stabilization mechanism 900 with respect to the sensor assembly 910 does not affect the driving of the driving member 210. 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 900 can be tested independently, thereby reducing the difficulty of testing the imaging module 1000. The imaging module 1000 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.

[0068] 15, specifically, the imaging module 1000 further includes a bottom case 820, which, together with the housing 800, surrounds and fixes the lens assembly 100, a focus mechanism, a blade driving mechanism, and an image stabilization mechanism 900. Preferably, the bottom case 820 may be made of a magnetic material.

[0069] In this embodiment, the image stabilization mechanism 900 includes an image stabilization base 920 and a movable holder 930, the movable holder 930 is located on the object side of the image stabilization base 920 and is movable in a direction perpendicular to the optical axis relative to the image stabilization base 920, and the sensor assembly 910 is fixed to the movable holder 930. Thereby, the sensor assembly 910 is driven to move by moving the movable holder 930, thereby realizing the image stabilization function of the imaging module 1000.

[0070] Specifically, the image stabilization base 920 is provided with a plurality of image stabilization magnet steels 921 arranged at intervals around the optical axis, the movable holder 930 is provided with a plurality of fixing yokes 931 arranged at intervals around the optical axis, at least three balls 933 are sandwiched between the image stabilization base 920 and the movable holder 930, and the image stabilization magnet steels 921 and the fixing yokes 931 attract each other, bringing the image stabilization base 920 and the movable holder 930 closer to each other and clamping all the balls 933. Since the balls 933 are spherical, the movable holder 930 is movable relative to the image stabilization base 920 when the balls 933 roll.

[0071] More specifically, the image stabilization base 920 is provided with a plurality of first storage grooves 922, the movable holder 930 is provided with a plurality of second storage grooves (not shown), the plurality of balls 933 correspond one-to-one to the plurality of first storage grooves 922 and are located within the first storage groove 922, and the plurality of second storage grooves correspond one-to-one to the plurality of first storage grooves 922. By storing the ball 933 using a storage groove, the motion range of the ball 933 can be limited, the ball 933 can be prevented from falling off, and the stability of the imaging module 1000 can be increased.

[0072] In this embodiment, a first spacer 922a is provided in each of the first receiving grooves 922, and a second spacer 932a is provided in each of the second receiving grooves 922. The first spacer 922a and the second spacer 932a are both used to support the balls 933.

[0073] In this embodiment, the image stabilization mechanism 900 includes a coil holder 940 fixed to the movable holder 930, and the coil holder 940 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 921. When energized, the image stabilization coil generates a Lorentz magnetic force between the image stabilization magnet steel 922 and the coil holder 940 to move in a direction perpendicular to the optical axis, driving the movable holder 930 to move synchronously, and when the movable holder 930 moves, the sensor assembly 910 moves following the movable holder 930, thereby realizing image stabilization of the imaging module 1000.

[0074] That is, the image stabilization base 920 and the movable holder 930 are relatively fixed in the extending direction of the optical axis by the attractive force between the image stabilization magnet steel 921 and the fixing yoke 931, and the ball 933 can roll in the first receiving groove 922 and the receiving groove, i.e., the ball 933 can roll relative to the image stabilization base 920 and the movable holder 930, and when the movable holder 930 is subjected to the Lorentz force between the image stabilization magnet steel 921 and the image stabilization coil, the movable holder 930 moves relative to the image stabilization base 920 in a plane perpendicular to the optical axis. This allows the sensor assembly 910 to move in a plane perpendicular to the optical axis, thereby achieving image stabilization.

[0075] Specifically, in this embodiment, the imaging module 1000 supplies power to the multiple image stabilization coils through a circuit board 950 .

[0076] In this embodiment, a mounting hole 923 is provided in the image stabilization base 920, a damping member 923a is provided in the mounting hole 923, and the damping member 923a penetrates the mounting hole 923 and contacts the bottom case 820 and the sensor assembly 910, respectively, and more specifically, the bottom case 820 and the sensor assembly 910 sandwich the damping member 923a to slightly deform the damping member 923a. As a result, the damping member 923a provides resistance when the sensor assembly 910 moves, slowing down the movement speed of the sensor assembly 910 and preventing excessive vibration caused by too fast movement of the sensor assembly 910 during image stabilization.

[0077] For example, in this embodiment, the number of the mounting holes 923 and the damping members 923a is four, and they are all spaced apart around the optical axis. Here, the damping members 923a are made of rubber. As can be appreciated, the number of the mounting holes 923 and the damping members 923a can be set to other numbers, and the damping members 923a can be made of silica gel material or other materials that have a certain elasticity and can provide friction resistance.

[0078] 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.

[0079] 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.

[0080] 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.

[0081] 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.
