DETAILED DESCRIPTION

[0035] In order to make the purpose, technical scheme and advantages of the present application clearer, the technical scheme of the present application will be described clearly and completely below in combination with the embodiments of the present application and corresponding drawings. Obviously, the described embodiments are only some of the embodiments of the present application, but not all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without making any creative effort fall within the scope of protection of the present application.

[0036] In the description of the present application, it should be noted that unless otherwise explicitly specified and limited, the terms “mounting”, “connecting”, “connecting” should be understood broadly, for example, it can be fixed connection, or detachable connection, or integrally connected; it can be directly connected, or indirectly connected through an intermediate medium, or the communication inside two elements. For those skilled in the art, the specific meaning of the above terms in the present application can be understood according to the specific circumstances.

[0037] In addition, although the terms used in the present application are selected from the commonly known and used terms, some terms mentioned in the description of the present application may be selected by the applicant according to his or her judgment, and the detailed meaning of which is described in the relevant part of the description.

[0038] Furthermore, the present application is to be interpreted not only by the actual terms used but also by the meanings of each term.

[0039] The technical solutions provided by the embodiments of the present application are described in detail below with reference to the drawings.

[0040] The embodiments of the present application provide a camera device. Referring to Figures 1 to 11 The camera device 1 provided by the embodiments of the present application comprises a camera module 10 and an aperture module 20.

[0041] The camera module 10 comprises a lens 11 and a driver 12 drivingly connected with the lens 11. Exemplarily, the driver 12 can be an Auto Focus (AF) motor. The driver 12 can drive the lens 11 to perform telescopic movement to adjust the focal length of the lens 11 to obtain a clear image.

[0042] The aperture module 20 comprises a plurality of aperture blades 21, a support 22 and a plurality of transmission members 23. The aperture blades 21 are a group of overlapping sheet-shaped components for adjusting the aperture in the aperture module 20. After the aperture blades 21 are combined, a light passing hole 21a in a circular shape is formed in the center, and the size of the light passing hole 21a can be adjusted by adjusting the aperture blades 21. It can be understood that the larger the aperture of the light passing hole 21a, the more light enters the camera module 10.

[0043] Specifically, in the embodiments of the present application, the plurality of aperture blades 21 are arranged on the light entering side of the lens 11 and are distributed in a circle around the optical axis 11a of the lens 11. The area surrounded by the plurality of aperture blades 21 forms the light passing hole 21a. Each aperture blade 21 is slidingly connected with the support 22 in a direction perpendicular to the optical axis 11a, each transmission member 23 is drivingly connected with the aperture blade 21 one by one, and the driver 12 is further drivingly connected with each transmission member 23.

[0044] In the case that the driver 12 drives the lens 11 to move, each transmission member 23 moves synchronously with the lens 11, and each transmission member 23 drives each aperture blade 21 to move synchronously towards or away from the optical axis 11a to adjust the aperture size of the light passing hole 21a.

[0045] In this way, in the embodiments of the present application, since the driver 12 is drivingly connected with the lens 11 and the transmission member 23 respectively, and the transmission member 23 is drivingly connected with the aperture blade 21, during the process that the driver 12 drives the lens 11 to move, the driver 12 can synchronously drive the transmission member 23 to move, so as to drive the aperture blade 21 to move towards the direction of approaching or moving away from the optical axis 11a by the transmission member 23, to adjust the aperture size of the light passing hole 21a. Therefore, the aperture blade 21 can move with the movement of the lens 11, so as to make the aperture of the light passing hole 21a be coupled with the displacement of the lens 11.

[0046] It should be noted that in some shooting scenes, when shooting a distant scene, the lens 11 can be retracted, so that the camera device 1 is in a telephoto state, and at the same time, the aperture blade 21 can be expanded to increase the aperture of the light passing hole 21a. That is, the telephoto aperture is increased. In some shooting scenes, when shooting a close-up scene, the lens 11 can be extended, so that the camera device 1 is in a close-up state, and at the same time, the aperture blade 21 can be retracted to reduce the aperture of the light passing hole 21a. That is, the close-up aperture is reduced.

[0047] To cope with this shooting scene, in some embodiments, when the driver 12 drives the lens 11 to move towards the direction of approaching the aperture blade 21, each transmission member 23 moves synchronously with the lens 11, and each transmission member 23 drives each aperture blade 21 to move synchronously towards the direction of approaching the optical axis 11a, to reduce the aperture of the light passing hole 21a. When the driver 12 drives the lens 11 to move away from the aperture blade 21, each transmission member 23 moves synchronously with the lens 11, and each transmission member 23 drives each aperture blade 21 to move synchronously away from the direction of the optical axis 11a, to increase the aperture of the light passing hole 21a.

[0048] Therefore, by using the scheme provided in the embodiments of the present application, the aperture of the light passing hole 21a of the aperture module 20 can be adjusted by the driver of the camera module 10, so that when the lens 11 is in a close-up state, a small aperture is automatically switched, so as to increase the depth of field and enhance the resolving power. When the lens 11 is in a telephoto state, a large aperture is automatically switched. Without separately configuring a driver for driving the aperture blade 21 for the aperture module 20, the aperture of the aperture module is coupled with the displacement of the lens by a simple control algorithm.

[0049] It should be noted that in the related art, there are many transmission mechanisms that can convert vertical movement into horizontal movement. Exemplarily, a cross slide mechanism can convert vertical movement into horizontal movement. For example, the cross slide mechanism includes a first slide groove, a second slide groove, a first sliding block, a second sliding block, and a connecting rod. The first slide groove and the second slide groove are perpendicular to each other, the first sliding block is in sliding fit connection with the first slide groove, the second sliding block is in sliding fit connection with the second slide groove, and the two ends of the connecting rod are hingedly connected with the first sliding block and the second sliding block respectively. Thus, in the process of pushing the first sliding block to move up and down along the first slide groove, the second sliding block can move horizontally along the second slide groove.

[0050] Those skilled in the art can refer to the mechanism for converting vertical movement into horizontal movement in the related art to set the transmission structure between the transmission member 23 and the aperture blade 21 in the process of implementing the scheme provided by the embodiments of the present application. Of course, in order to facilitate those skilled in the art to better implement the scheme provided by the embodiments of the present application, the transmission scheme between the transmission member 23 and the aperture blade 21 is provided below for those skilled in the art to refer to.

[0051] Reference Figure 5 In some embodiments, the aperture blade 21 includes a blade body 211 and a sliding member 212 connected with each other. Reference Figure 3 and Figure 4 The transmission member 23 is provided with a first slide groove 231. The sliding member 212 is in sliding fit connection with the first slide groove 231. Exemplarily, the sliding member 212 is embedded in the first slide groove 231, so that the sliding member 212 can slide relative to the first slide groove 231 along the extension direction of the first slide groove 231. In this way, in combination Figure 3 and 8 In the process of driving the transmission member 23 to move up and down by the driver 12, the groove wall of the first slide groove 231 can push the sliding member 212 to slide horizontally, and in turn can drive the blade body 211 to slide, so as to achieve the effect of adjusting the aperture size of the light passage hole 21a.

[0052] Reference Figure 4 In some embodiments, the first slide groove 231 includes a first position 2311 and a second position 2312 which are spaced apart along the extension direction of the first slide groove 231. Exemplarily, the first slide groove 231 includes a first end and a second end along the extension direction thereof, the first position 2311 is located at the first end, and the second position 2312 is located at the second end.

[0053] Reference Figure 8 and Figure 9 In the case that the lens 11 moves to the outermost limit position, the sliding member 212 is located at the first position 2311. In other words, in the case that the lens 11 is stretched to the top, the sliding member 212 slides relative to the first slide groove 231 to the first position 2311 which is located below the first slide groove 231. Reference Figure 3 andFigure 4 In the case that the lens 11 moves to the innermost limit position, the sliding member 212 is located at the second position 2312. In other words, in the case that the lens 11 is retracted to the bottom, the sliding member 212 slides relative to the first sliding groove 231 to the second position 2312 which is located above the first sliding groove 231.

[0054] In the direction parallel to the optical axis 11a, the first position 2311 and the second position 2312 are spaced apart by a first distance. In other words, referring to FIG. 2, the first position 2311 is located at the left side of the first sliding groove 231, and the second position 2312 is located at the right side of the first sliding groove 231. Figure 3 and Figure 4 In the vertical direction, the first position 2311 and the second position 2312 are staggered. In the direction parallel to the sliding direction of the aperture blade 21, the first position 2311 and the second position 2312 are spaced apart by a second distance. In other words, referring to FIG. 2, the first position 2311 is located at the lower side of the first sliding groove 231, and the second position 2312 is located at the upper side of the first sliding groove 231. Figure 3 and Figure 4 In the horizontal direction, the first position 2311 and the second position 2312 are not equidistant from the optical axis 11a. In this way, during the process that the driver 12 drives the transmission member 23 to ascend, for example, the transmission member 23 ascends by a first distance, the aperture blade 21 can slide horizontally by a second distance.

[0055] In some embodiments, in the direction from the first position 2311 to the second position 2312, the distance between the first sliding groove 231 and the optical axis 11a gradually increases. In other words, the second position 2312 is located on the side of the first position 2311 which is away from the optical axis 11a.

[0056] In this way, referring to FIG. 2, in the case that the lens 11 is retracted, the transmission member 23 descends, the upper side of the first sliding groove 231 pushes the sliding member 212 to move in the direction away from the optical axis 11a, and then the sliding member 212 can drive the aperture blade 21 to expand. Figure 3 and Figure 4 In the case that the lens 11 is extended, the transmission member 23 ascends, the lower side of the first sliding groove 231 pushes the sliding member 212 to move in the direction close to the optical axis 11a, and then the sliding member 212 can drive the aperture blade 21 to retract. Figure 8 and Figure 9 In the case that the lens 11 is extended, the transmission member 23 ascends, the lower side of the first sliding groove 231 pushes the sliding member 212 to move in the direction close to the optical axis 11a, and then the sliding member 212 can drive the aperture blade 21 to retract.

[0057] Further, when shooting a far scene, the driver 12 drives the lens 11 to retract, the camera 1 switches to a telephoto state, and at the same time, the driver 12 drives the transmission member 23 to descend, the transmission member 23 pushes the sliding member 212 to move away from the optical axis 11a, and the sliding member 212 drives the aperture blade 21 to expand, thereby realizing automatic aperture enlargement in the telephoto state. When shooting a close scene, the driver 12 drives the lens 11 to extend, the camera 1 switches to a close-up state, and at the same time, the driver 12 drives the transmission member 23 to ascend, the transmission member 23 pushes the sliding member 212 to move close to the optical axis 11a, and the sliding member 212 drives the aperture blade 21 to retract, thereby realizing automatic aperture reduction in the close-up state.

[0058] Therefore, by using the scheme provided in the embodiments of the present application, automatic aperture enlargement in the telephoto state and automatic aperture reduction in the close-up state can be realized by mechanical transmission, without the need to separately configure a driver for driving the aperture blade 21 for the aperture module 20, and without the need for a complex control algorithm to couple the aperture of the aperture module and the displacement of the lens.

[0059] Reference Figure 4 In some embodiments, the first sliding groove 231 extends along a straight line. In this way, the inclination angle of the first sliding groove 231 can be set based on the extension / retraction displacement of the lens 11 and the aperture adjustment amount of the aperture of the aperture module 20.

[0060] For example, the angle between the first sliding groove 231 and the horizontal direction is θ, and then the moving distance δr of the aperture blade 21 after being driven by the first sliding groove 231 is δh / tanθ when the lens moves up by δh.

[0061] For example, during the focusing process of a certain lens from infinity to 15 cm, the lens moves up by 0.54 mm, the original aperture of the aperture module is 2.4 mm, the effective focal length is 8.67 mm, and the aperture F number is f / 1.8. The aperture module changes to a small aperture f / 4.0, and the radius is reduced by 1.3 mm. That is, δr=1.3 mm. The lens moves up by δh=0.54 mm during the focusing process, and θ=arctan(δh / δr)=arctan(0.54 / 1.3)=22.56 degrees can be obtained. In this way, the angle between the first sliding groove 231 and the horizontal direction is set to 22.56 degrees, so that the aperture module corresponding to the lens with an effective focal length of 8.67 mm and an aperture F number of f / 1.8 can change from f / 1.8 to f / 4.0.

[0062] Of course, for example, in some embodiments, the first sliding groove 231 can also extend along a broken line or a curve. Those skilled in the art can flexibly set the specific shape of the first sliding groove 231 according to actual needs during the implementation of the scheme provided in the embodiments of the present application, which will not be listed one by one here.

[0063] Reference Figure 11 In some embodiments, the bracket 22 comprises a plurality of bearing rings 221 and a plurality of cover rings 222 arranged at intervals. A plurality of second sliding grooves 223 are arranged between the bearing rings 221 and the cover rings 222, and the plurality of second sliding grooves 223 are distributed in a circle around the optical axis 11a. Reference Figure 5 The aperture blade 21 further comprises a connecting piece 213. The sliding piece 212 is connected with the blade body 211 through the connecting piece 213. In combination Figure 1 The connecting piece 213 is slidingly arranged in the second sliding groove 223 one by one. In this way, the aperture blade 21 can be slidingly guided by the second sliding groove 223.

[0064] It should be noted that in some embodiments, the intersection of the extension lines of each second sliding groove 223 is located on the optical axis 11a. In other words, the aperture blade 21 can slide relative to the bracket 22 in the radial direction of the optical axis 11a.

[0065] Reference Figure 10 In some embodiments, the lens 11 comprises an optical lens 111 and a lens barrel 112. The lens barrel 112 is sleeved outside the optical lens 111. The plurality of transmission members 23 are distributed in a circle around the optical axis 11a of the lens 11, and are respectively connected with the lens barrel 112. In this way, the transmission members 23 can move synchronously with the lens 11.

[0066] Exemplarily, the number of the transmission members 23 can be 3, 4, 5, 6, 7, 8, etc. The number of the aperture blades 21 is equal to the number of the transmission members 23, and the transmission members 23 are in one-to-one transmission connection with the aperture blades 21 to drive the aperture blades 21 to translate.

[0067] Reference Figure 11 In some embodiments, the driver 12 comprises a housing 121. The bracket 22 is connected with the housing 121. In combination Figure 1 and Figure 3 The bracket 22 is provided with a through hole 224, and the axis of the through hole 224, the axis of the light passing hole 21a and the axis of the optical axis 11a all coincide. The aperture of the through hole 224 is larger than the aperture of the light passing hole 21a, so that the light can pass through the through hole 224 and be emitted to the camera compact module 10 through the light passing hole 21a.

[0068] It should be noted that the camera compact module (CCM for short) is also called camera or camera module. Exemplarily, the camera compact module generally comprises a lens, a voice coil motor (VCM for short), a sensor, a flexible printed circuit (FPC for short) and a digital signal processing (DSP for short) chip, etc.

[0069] The working principle of the camera module is that light gathered by the lens of an object is converted into an electrical signal by a complementary metal-oxide-semiconductor (CMOS) sensor or a charge-coupled device (CCD) sensor, and then converted into a digital image signal by an internal image processor and output to a digital signal processing technology chip for processing, and converted into a standard format image signal.

[0070] Therefore, in some embodiments, in the case that the camera module 10 is a camera module similar to the above example, the driver 12 can be a voice coil motor, which can be used to drive the lens 11 and the transmission member 23 to move synchronously. In addition, it should be noted that the specific structure and the number of the blade bodies 211 of the aperture blades 21 can refer to the related art, and the arrangement manner of the blade bodies 211 can also refer to the related art, or the number, shape or arrangement manner of the blade bodies 211 can be flexibly adjusted according to actual needs by those skilled in the art.

[0072] It should be noted that, in this document, the relationship terms such as first and second are used only to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply that there is any such actual relationship or order between these entities or operations. Moreover, the terms "include", "contain" or any other variants thereof are intended to cover non-exclusive inclusion, so that the process, method, article or device including a series of elements not only includes those elements, but also includes other elements not explicitly listed or inherent to such process, method, article or device.
