光阑装置、摄像模组和电子设备Aperture devices, camera modules and electronic equipment

技术领域technical field

背景技术Background technique

光阑装置的主要作用是调整图像感应器的受光量。具体的,当把光阑装置中的通光通孔调大,那么进入相机的光量就多,光阑装置中的通光通孔调小,那么进入相机的光量就少。传统的光阑装置通光多个叶片组装形成光圈通孔,并通过调节各叶片的位置调光圈通孔的大小。The main function of the diaphragm device is to adjust the amount of light received by the image sensor. Specifically, when the light-passing through hole in the diaphragm device is increased, the amount of light entering the camera is increased, and the light-transmitting hole in the diaphragm device is decreased, so the light amount entering the camera is less. In a traditional diaphragm device, a plurality of blades are assembled to form an aperture through hole, and the size of the aperture through hole is adjusted by adjusting the position of each blade.

传统光阑装置的结构复杂,在用微小摄像头的情况下,叶片结构尺寸微小,难以量产和装配,并且,光圈通孔的圆度难以品控,进而不能精准调整图像感应器的受光量。The structure of the traditional aperture device is complicated. In the case of a tiny camera, the size of the blade structure is small, which makes it difficult to mass-produce and assemble. In addition, the roundness of the aperture through hole is difficult to quality control, and the amount of light received by the image sensor cannot be accurately adjusted.

具体实施方式Detailed ways

下面将结合本申请实施例中的附图,对本申请实施例中的技术方案进行清楚、完整地描述,显然,所描述的实施例是本申请一部分实施例,而不是全部的实施例。基于本申请中的实施例,本领域普通技术人员在没有作出创造性劳动前提下所获得的所有其他实施例,都属于本申请保护的范围。The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present application.

For example, the first object may be one or more than one. In addition, "and/or" in the description and claims indicates at least one of the connected objects, and the character "/" generally indicates that the associated objects are in an "or" relationship.

下面结合附图1至图10,通过具体的实施例及其应用场景对本申请实施例提供的光阑装置、摄像模组和电子设备进行详细地说明。The aperture device, the camera module, and the electronic equipment provided by the embodiments of the present application will be described in detail below with reference to FIGS. 1 to 10 , through specific embodiments and application scenarios.

参照图1至图6,本发明实施例公开的光阑装置,包括壳体100、柔性遮光件200和第一驱动件300。壳体100为基础结构件,为柔性遮光件200和/或第一驱动件300提供安装基础。Referring to FIGS. 1 to 6 , the aperture device disclosed in the embodiment of the present invention includes a housing 100 , a flexible light shielding member 200 and a first driving member 300 . The housing 100 is a basic structural member, and provides a mounting base for the flexible light shielding member 200 and/or the first driving member 300 .

参照图1至图10,壳体100可以具有通光通道。第一驱动件300和柔性遮光件200可以设置于壳体100。参照图2和图4,柔性遮光件200可以具有通光孔,且通光孔可以与通光通道相对。可选的,通光孔可以设置为圆形孔,以保证通光孔的圆度。具体的,柔性遮光件200可以设置为环形或筒状。当然,还可以根据需要将通光孔设置为其他形状,例如正多边形、椭圆形、心形等。本实施例不限定通光孔的具体形状。进一步的,通光通道的截面形状与通光孔的截面形状相同。可选的,通光通道可以设置为圆柱形,通光通道可以与通光孔同轴设置,以提高光阑装置结构的紧凑性。Referring to FIGS. 1 to 10 , the housing 100 may have a light passage. The first driving member 300 and the flexible light shielding member 200 may be disposed on the housing 100 . Referring to FIG. 2 and FIG. 4 , the flexible light shielding member 200 may have a light-passing hole, and the light-passing hole may be opposite to the light-passing channel. Optionally, the light-passing hole can be set as a circular hole to ensure the roundness of the light-passing hole. Specifically, the flexible light shielding member 200 may be arranged in a ring shape or a cylindrical shape. Of course, the light-transmitting holes can also be set to other shapes as required, such as regular polygons, ellipses, hearts, and the like. This embodiment does not limit the specific shape of the light-transmitting hole. Further, the cross-sectional shape of the light-passing channel is the same as that of the light-passing hole. Optionally, the light-passing channel may be set in a cylindrical shape, and the light-passing channel may be arranged coaxially with the light-passing hole, so as to improve the compactness of the structure of the aperture device.

第一驱动件300可以驱动柔性遮光件200在第一状态和第二状态之间切换。在柔性遮光件200处于第一状态的情况下,柔性遮光件200至少部分遮挡通光通道,且柔性遮光件200的通光孔的孔径为第一孔径。在柔性遮光件200处于第二状态的情况下,柔性遮光件200的通光孔的孔径为第二孔径,第二孔径大于第一孔径。第一驱动件300通过作用柔性遮光件200,使柔性遮光件200可以发生形变。具体的,柔性遮光件200可以在第一状态和第二状态之间切换,以调节通光通道的通光量的大小。在柔性遮光件200由第一状态向第二状态切换的过程中,第一驱动件300作用柔性遮光件200,使得柔性遮光件200的通光孔的孔径逐渐增加,通光通道被遮挡部分的面积逐渐减小,进而增加通光通道的通光量。在柔性遮光件200由第二状态向第一状态切换的过程中,第一驱动件300作用柔性遮光件200,使得柔性遮光件200的通光孔的孔径逐渐减小,通光通道的被遮挡部分的面积逐渐增加,进而减小通光通道的通光量。The first driving member 300 may drive the flexible light shielding member 200 to switch between the first state and the second state. When the flexible light shielding member 200 is in the first state, the flexible light shielding member 200 at least partially shields the light passage, and the aperture of the light passage hole of the flexible light shielding member 200 is the first aperture. When the flexible light-shielding member 200 is in the second state, the aperture of the light-transmitting hole of the flexible light-shielding member 200 is the second aperture, and the second aperture is larger than the first aperture. The first driving member 300 can deform the flexible light shielding member 200 by acting on the flexible light shielding member 200 . Specifically, the flexible light shielding member 200 can be switched between the first state and the second state to adjust the amount of light passing through the light passing channel. During the process of switching the flexible light-shielding member 200 from the first state to the second state, the first driving member 300 acts on the flexible light-shielding member 200, so that the aperture of the light-transmitting hole of the flexible light-shielding member 200 gradually increases, and the shielded part of the light-passing channel The area gradually decreases, thereby increasing the amount of light passing through the light channel. In the process of switching the flexible light-shielding member 200 from the second state to the first state, the first driving member 300 acts on the flexible light-shielding member 200, so that the aperture of the light-passing hole of the flexible light-shielding member 200 is gradually reduced, and the light-passing channel is blocked. The area of the part gradually increases, thereby reducing the amount of light passing through the light channel.

上述实施例中所述的光阑装置与传统的光阑装置相比,结构更加简单,不仅可以减小光阑装置的体积,还能降低光阑装置的制造难度和制造成本。第一驱动件300驱动柔性遮光件200发生形变,可以是但不限于第一驱动件300与柔性遮光件200之间相互挤压或拉动致使柔性遮光件200受力形变。具体的,可以通过控制第一驱动件300作用在柔性遮光件200上的作用力的大小,或者是拉动柔性遮光件200移动的距离调节柔性遮光件200的形变量,进而调节柔性遮光件200的通光孔的大小,使得通光孔的孔径可以在第一驱动件300的作用下连续变化。由于通光孔的孔径可以实现连续变化,进而可以在柔性遮光件200的形变范围内实现通光孔的孔径大小的无极调节。并且,上述实施例中所述的光阑装置在调节通光孔大小的过程中,通光孔的圆度可以保持不变,进而可以避免通光孔圆度对通光孔的孔径大小的调节范围的限制。需要说明的是,通光多叶片围合形成通光孔的光阑装置中,通光孔的孔径越大,通光孔的圆度越差,进而使得通光孔的孔径大小的调节范围受限。Compared with the traditional diaphragm device, the diaphragm device described in the above embodiments has a simpler structure, which can not only reduce the volume of the diaphragm device, but also reduce the manufacturing difficulty and manufacturing cost of the diaphragm device. The first driving member 300 drives the flexible shading member 200 to deform, which may be, but not limited to, the first driving member 300 and the flexible shading member 200 are squeezed or pulled with each other to cause the flexible shading member 200 to be deformed by force. Specifically, the deformation amount of the flexible light-shielding member 200 can be adjusted by controlling the magnitude of the force acting on the flexible light-shielding member 200 by the first driving member 300 , or by pulling the moving distance of the flexible light-shielding member 200 , thereby adjusting the deformation of the flexible light-shielding member 200 . The size of the light-passing hole is such that the aperture of the light-passing hole can be continuously changed under the action of the first driving member 300 . Since the aperture of the light-passing hole can be continuously changed, the stepless adjustment of the aperture of the light-passing hole can be realized within the deformation range of the flexible light shielding member 200 . In addition, in the process of adjusting the size of the light-transmitting hole in the diaphragm device described in the above-mentioned embodiments, the circularity of the light-passing hole can remain unchanged, thereby avoiding the adjustment of the aperture size of the light-passing hole by the circularity of the light-passing hole. scope limit. It should be noted that, in the aperture device in which the light-passing multi-blade is enclosed to form the light-passing hole, the larger the aperture of the light-passing hole is, the worse the circularity of the light-passing hole is, so that the adjustment range of the aperture size of the light-passing hole is limited. limit.

第一驱动件300与柔性遮光件200的连接部可以为环形,且第一驱动件300与柔性遮光件200的连接部与通光孔同心设置,以进一步提高通光孔四周受力大小的均匀度,提高通光孔四周的形变量的一致性,进而可以在通光孔的孔径变化的过程中,进一步提高通光孔的圆度。The connecting portion of the first driving member 300 and the flexible shading member 200 can be annular, and the connecting portion of the first driving member 300 and the flexible shading member 200 is arranged concentrically with the light-passing hole, so as to further improve the uniformity of the force around the light-passing hole. In order to improve the consistency of the deformation around the light-passing hole, the roundness of the light-passing hole can be further improved in the process of changing the aperture of the light-passing hole.

柔性遮光件200可以为弹性体材料制成,以使柔性遮光件200可以在自身弹力的作用下恢复形变,即在第一驱动件300作用在柔性遮光件200上的作用力减小或消失的情况下,柔性遮光件200可以在自身弹力的作用下恢复形变,进而可以保证柔性遮光件200反复形变后仍可以恢复初始状态的形状,保证通光孔形状的一致性。The flexible light shielding member 200 can be made of an elastomer material, so that the flexible light shielding member 200 can recover and deform under the action of its own elastic force, that is, when the force acting on the flexible light shielding member 200 by the first driving member 300 is reduced or disappeared. Under certain circumstances, the flexible light shielding member 200 can recover its deformation under the action of its own elastic force, thereby ensuring that the flexible light shielding member 200 can still restore the shape of the initial state after repeated deformation, and the consistency of the shape of the light-passing hole can be ensured.

柔性遮光件200可以为弹性体材料制成。弹性体材料的种类有很多,例如:聚酯弹性体材料、丙烯基弹性体材料、乙烯基弹性体材料、氟/硅弹性体材料等。因此本申请不限定柔性遮光件200的具体材质。The flexible shade 200 may be made of an elastomeric material. There are many types of elastomeric materials, such as: polyester elastomeric materials, propylene-based elastomeric materials, vinyl elastomeric materials, fluorine/silicon elastomeric materials, and the like. Therefore, the present application does not limit the specific material of the flexible light shielding member 200 .

参照图1和图2,在柔性遮光件200不受外力作用的情况下,即柔性遮光件200处于自然状态下,柔性遮光件200的通光孔的孔径可以小于或等于第一孔径。第一驱动件300作用柔性遮光件200,使柔性遮光件200的孔径增大,使得通光通道的通光量增加。当第一驱动件300作用在柔性遮光件200上的作用力减小或消失的情况下,柔性遮光件200可以在自身弹力的作用下恢复形变,柔性遮光件200的通光孔的孔径减小,进而使得通光通道的通光量减小。1 and 2 , when the flexible light shielding member 200 is not affected by external force, that is, the flexible light shielding member 200 is in a natural state, the aperture of the light-transmitting hole of the flexible light shielding member 200 may be smaller than or equal to the first aperture. The first driving member 300 acts on the flexible light shielding member 200, so that the aperture of the flexible light shielding member 200 is increased, so that the amount of light passing through the light passage channel is increased. When the force of the first driving member 300 acting on the flexible light shielding member 200 decreases or disappears, the flexible light shielding member 200 can recover its deformation under the action of its own elastic force, and the aperture of the light-passing hole of the flexible light shielding member 200 is reduced. , thereby reducing the amount of light passing through the light passage.

参照图9和图10,在柔性遮光件200不受外力作用的情况下,即柔性遮光件200处于自然状态下,柔性遮光件200的通光孔的孔径大于或等于第二孔径。第一驱动件300通过作用柔性遮光件200,使柔性遮光件200中通光孔的孔径减小,使得通光通道的通光量减小。当第一驱动件300作用在柔性遮光件200上的作用力减小或在消失的情况下,柔性遮光件200可以在自身弹力的作用下恢复形变,柔性遮光件200的通光孔的孔径减小,进而使得通光通道的通光量减小。9 and 10 , when the flexible light shielding member 200 is not affected by external force, that is, the flexible light shielding member 200 is in a natural state, the aperture of the light-transmitting hole of the flexible light shielding member 200 is greater than or equal to the second aperture. The first driving member 300 reduces the aperture of the light-passing hole in the flexible light-shielding member 200 by acting on the flexible light-shielding member 200, so that the light-passing amount of the light-passing channel is reduced. When the force of the first driving member 300 acting on the flexible light-shielding member 200 is reduced or disappears, the flexible light-shielding member 200 can recover its deformation under the action of its own elastic force, and the aperture of the light-transmitting hole of the flexible light-shielding member 200 decreases. is small, thereby reducing the amount of light passing through the light channel.

当然,在柔性遮光件200不受外力作用的情况下,柔性遮光件200的通光孔的孔径还可以位于第一孔径和第二孔径之间。具体的,第一驱动件300可以驱动柔性遮光件200的孔径增加或缩小。为此,本申请实施例不限定柔性遮光件200在不受外力作用的情况下柔性遮光件200的通光孔的孔径的具体大小。Certainly, under the condition that the flexible light shielding member 200 is not affected by external force, the aperture of the light-transmitting hole of the flexible light shielding member 200 may also be located between the first aperture and the second aperture. Specifically, the first driving member 300 can drive the aperture of the flexible light shielding member 200 to increase or decrease. Therefore, the embodiment of the present application does not limit the specific size of the aperture of the light-passing hole of the flexible light-shielding member 200 under the condition that the flexible light-shielding member 200 is not affected by external force.
