Description

Technical Field

[0001] This application relates to the field of camera technology, and more particularly to a camera module and electronic device. Background Technology

[0002] With the rapid development of telephoto photography in electronic devices (such as smartphones), consumers have increasingly higher demands for telephoto video recording. Achieving telephoto video recording involves using a camera module with a long focal length to capture the subject. Telephoto camera modules can clearly capture subjects at greater distances; however, current telephoto camera modules suffer from a large size, making the reduction of their size within electronic devices a pressing issue that needs to be addressed. Utility Model Content

[0003] This application provides a camera module and an electronic device.

[0004] In a first aspect, this application provides a camera module, which includes a condenser lens, a first reflector, a focusing lens group, a second reflector, and an image sensor. The condenser lens and the first reflector are arranged opposite to each other along a first direction. The first reflector is used to change the optical axis parallel to the first direction to a second direction. The focusing lens group is located between the first reflector and the second reflector in the second direction. The optical axis of the focusing lens group is parallel to the second direction. The second reflector is used to change the optical axis of the second direction to the first direction. The image sensor and the condenser lens are located on opposite sides of the second reflector along the first direction. The light emitted from the focusing lens group is reflected once by the second reflector and then emitted to the image sensor. The first direction and the second direction intersect.

[0005] By employing a folded optical path through a condenser lens, a first reflector, and a second reflector, the camera module achieves telephoto shooting while maintaining a relatively small overall height and volume, resulting in a low-profile design. Furthermore, the image sensor is located on the side of the second reflector away from the condenser lens, reducing physical interference during assembly. This allows the image sensor's photosensitive surface to be larger, freed from the limitations imposed by the condenser lens. Simultaneously, light emitted from the focusing lens group only needs to be reflected once by the second reflector before reaching the image sensor, minimizing reflections on the second reflector and improving image quality.

[0006] In conjunction with the first aspect, in one possible implementation, the camera module further includes a first base and a first housing, the first base housing a focusing lens. The first housing houses a focusing lens assembly, and the side of the first housing facing the focusing lens along a first direction has a first notch, at least a portion of the first notch connecting the interior of the first base and the interior of the first housing, at least a portion of the focusing lens passing through the first notch and located within the first housing.

[0007] The first notch can avoid the focusing and reflecting lens in the first installation space. At least part of the first reflective surface of the focusing and reflecting lens can penetrate the first notch and extend into the first housing, reducing the shoulder height of the camera module. At the same time, it improves the space utilization of the first housing, which is conducive to realizing the small size design of the camera module.

[0008] In conjunction with the first aspect, in one possible implementation, the first base has a first mounting space and a second mounting space that are connected. The first mounting space houses a focusing and reflecting lens, and the second mounting space houses a first reflector. The camera module also includes a second base housed within a first housing. The second base and the first reflector are arranged along a second direction. The second base has a third mounting space that is connected to the first mounting space through at least a portion of a first notch.

[0009] Fixing the condenser lens and the first reflector to the same base can reduce the relative displacement between the condenser lens and the first reflector caused by external vibration or impact, ensuring long-term alignment of the optical path and thus guaranteeing the imaging quality of the camera module.

[0010] In conjunction with the first aspect, in one possible implementation, the first base has a first mounting space that houses a focusing and reflecting lens. The camera module also includes a second base, which is arranged along a first direction with the first base. The second base has a communicating second mounting space and a third mounting space. The second mounting space houses a first reflector. The portion of the second base that encloses the third mounting space is located within a first housing. The third mounting space houses a focusing lens assembly and communicates with the first mounting space through a first notch.

[0011] This design reduces the relative displacement between the focusing lens group and the first reflector caused by external vibrations or impacts, ensuring long-term alignment of the optical path and improving the focusing accuracy of the camera module.

[0012] In conjunction with the first aspect, in one possible implementation, the focusing and reflecting lens includes a first transmitting surface, a first reflecting surface, a second reflecting surface, and a second transmitting surface. The first transmitting surface and the second reflecting surface are located on the object-side surface of the focusing and reflecting lens. The first transmitting surface surrounds the second reflecting surface. The first reflecting surface and the second transmitting surface are located on the image-side surface of the focusing and reflecting lens. The first reflecting surface surrounds the second transmitting surface. At least a portion of the first reflecting surface penetrates a first notch within a first housing. Light from outside the camera module passes sequentially through the first transmitting surface, the first reflecting surface, the second reflecting surface, and the second transmitting surface before being projected onto the first reflector.

[0013] After being reflected multiple times within the focusing and reflecting lens, the light is emitted to the focusing lens group. The focusing lens group focuses and adjusts the light, thereby increasing the focal length of the camera module from less than 100mm to 300mm, achieving long focal length and large aperture shooting effects.

[0014] In conjunction with the first aspect, in one possible implementation, the focusing lens group includes a first lens group and a second lens group, with the first lens group disposed between the first reflector and the second lens group. The camera module also includes a focusing drive mechanism and a first carrier, the focusing drive mechanism being connected to the first carrier and used to drive the first carrier to move relative to the second base along a second direction. Parts of the first carrier and the focusing drive mechanism are both installed within a third mounting space. The first carrier and the first reflector are arranged along the second direction. The first carrier includes a first surface and a second surface disposed opposite to each other. At least one of the first lens group and the second lens group is disposed between the first surface and the second surface. The first surface is closer to the condenser lens in the first direction than the second surface. The minimum distance between the edge of the first surface facing the first reflector and the first reflective surface is greater than or equal to 0.1 mm and less than or equal to 0.6 mm.

[0015] As the first carrier moves along the second direction under the drive of the focusing drive mechanism, when the first carrier moves along the second direction, when the first carrier moves to a certain position, there is a minimum distance between the edge of the first surface facing the first reflector and the second reflector located in the third mounting space. The top of the second base has an opening, and there are no other devices between the first reflector located in the first housing and the first surface. The minimum distance is controlled to be greater than or equal to 0.1 mm and less than or equal to 0.6 mm to avoid the first carrier colliding with the first reflector during movement, and to prevent physical interference during the assembly of the first carrier and the condenser lens.

[0016] In conjunction with the first aspect, in one possible implementation, the first housing includes a light-emitting port and a first through-hole. The light-emitting port and the focusing lens assembly are disposed opposite each other along a second direction, and the first through-hole and the light-emitting port are disposed opposite each other along a third direction, which is perpendicular to the second direction and intersects the first direction. The camera module also includes a focusing flexible circuit board, part of which is located inside the first housing and connected to the focusing drive mechanism, and part of which passes through the first through-hole and is located outside the first housing.

[0017] The focusing flexible circuit board extends from the side of the first housing to the outside of the first housing. Compared with the focusing flexible circuit board extending from the top or bottom of the first housing, the size of the focusing flexible circuit board can be reduced, thereby reducing the space occupied by the focusing flexible circuit board in the camera module. Moreover, when the focusing flexible circuit board extends from the first through hole to the outside of the first housing, it is less likely to affect the light transmission at the light outlet.

[0018] In conjunction with the first aspect, in one possible implementation, the camera module further includes a second housing for accommodating the second reflector and the image sensor, the second housing having a second through-hole on the side facing the focusing and reflecting lens in the first direction. The camera module also includes a module circuit board, part of which is located inside the second housing, and part of which is located outside the second housing and electrically connected to a focusing flexible circuit board located outside the first housing.

[0019] The connection between the module circuit board and the focusing flexible circuit board is simple and easy to implement. At the same time, the connection position between the module circuit board and the focusing flexible circuit board is set on the outside of the first housing and the second housing, which can reduce the occupancy rate of the internal space of the first housing and the second housing, which is conducive to realizing the small size design of the camera module.

[0020] In conjunction with the first aspect, in one possible implementation, the inner wall surface of the second housing facing the second reflector is provided with a plurality of protruding structures, the plurality of protruding structures being located on the object side of the second reflector facing the focusing lens assembly.

[0021] The multiple protruding structures are closer to the focusing lens group in the second direction relative to the object side of the second reflector. The multiple protruding structures make the inner wall surface of the protrusions have an uneven texture, which causes the external stray light to scatter in random directions, reducing the light intensity in a specific direction, thereby reducing the possibility of entering the main optical path.

[0022] In conjunction with the first aspect, in one possible implementation, the optical axis of the focusing lens and the optical axis of the focusing lens group have a first angle, the value of which is greater than or equal to 84° and less than or equal to 96°.

[0023] This configuration reduces interference with the mounting of the condenser lens and decreases the overall height of the camera module. Specifically, when the first included angle is 90°, the first direction is perpendicular to the second direction. When the first included angle is less than 90°, the optical axis emanating from the focusing lens group can be tilted towards the condenser lens, and after passing through the second reflector, it can be redirected to the side away from the condenser lens along the first direction, further reducing the height of the camera module.

[0024] In conjunction with the first aspect, in one possible implementation, the first reflector includes a first incident surface, a third reflecting surface, and a first exiting surface. The first incident surface is disposed opposite to the second transmission surface of the condenser lens. The third reflecting surface is connected between the first incident surface and the first exiting surface. The third reflecting surface is disposed at a preset angle to the first exiting surface. The third reflecting surface is used to change the direction of light from the first incident surface to a second direction and illuminate the first exiting surface. The first exiting surface is disposed opposite to the image side of the focusing lens group.

[0025] In conjunction with the first aspect, in one possible implementation, the third reflecting surface and the first exiting surface have a second included angle, the value of which is greater than or equal to 42° and less than or equal to 48°.

[0026] In this way, the light emitted from the first exit surface can be tilted in the first direction toward the focusing and reflecting lens, which helps to reduce the overall height of the camera module and achieve a small-volume design for the camera module.

[0027] In conjunction with the first aspect, in one possible implementation, the second reflector includes a second incident surface, a fourth reflecting surface, and a second exiting surface. The second incident surface is disposed opposite to the focusing lens group along a second direction. The fourth reflecting surface is connected between the second incident surface and the second exiting surface and is used to reflect the light emitted from the second incident surface to the second exiting surface. The second exiting surface is disposed opposite to the image sensor along a first direction.

[0028] Secondly, this application provides an electronic device including a device housing and a camera module as provided in any implementation of the first aspect, the camera module being disposed within the device housing. Attached Figure Description

[0063] To make the objectives, technical solutions, and advantages of this application clearer, the application will now be described in further detail with reference to the accompanying drawings.

[0064] The object side is defined by the lens; the side where the object is located is called the object side, and the surface of the lens closest to the object side is called the object side surface.

[0065] The image side is the side on which the image of the subject is located, with the lens as the boundary. The surface of the lens closest to the image side is called the image side surface.

[0066] Aperture value, also known as F-number (Fno), is a relative value derived from the lens's focal length and entrance pupil diameter (EPD) (the reciprocal of the relative aperture). A smaller aperture value means a larger aperture, allowing more light to enter the lens in the same unit of time. A larger aperture value means a smaller aperture, resulting in a shallower depth of field, blurring the background and creating an effect similar to a telephoto lens.

[0067] The optical axis is a perpendicular axis passing through the center of a lens. The lens optical axis is the axis passing through the centers of all the lenses in the lens. When light rays parallel to the optical axis enter a convex lens, an ideal convex lens should have all the light rays converging at a single point behind the lens; this point where all the light rays converge is called the focal point.

[0068] "Multiple" can be at least two.

[0069] In the description of the embodiments of this application, it should be noted that, unless otherwise explicitly specified and limited, the term "connection" should be interpreted broadly. For example, "connection" can be a detachable connection or a non-detachable connection; it can be a direct connection or an indirect connection through an intermediate medium. "Fixed connection" refers to a connection where the relative positional relationship remains unchanged after the connection. The directional terms mentioned in the embodiments of this application, such as "top," "bottom," "inner," and "outer," are only for reference to the directions in the accompanying drawings. Therefore, the directional terms used are for better and clearer explanation and understanding of the embodiments of this application, and do not indicate or imply that the referred device or element must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the embodiments of this application. A or B is merely a description of the relationship between related objects, indicating that three relationships can exist: A alone, A and B simultaneously, and B alone. Hereinafter, the terms "first," "second," etc., are used for descriptive purposes only and should not be construed as implying or suggesting relative importance or implicitly indicating the number of indicated technical features. Therefore, features marked "first" or "second" can explicitly or implicitly include one or more of those features. Furthermore, in the embodiments of this application, mathematical concepts such as parallel and perpendicular are mentioned. These limitations are relative to the current technological level, rather than absolute and strict mathematical definitions, allowing for slight deviations; approximations of parallelism or perpendicularity are acceptable. For example, "A and B are parallel" means that A and B are parallel or approximately parallel, and the angle between A and B can be between 0 and 10 degrees.

[0070] The embodiments of this application are described below with reference to the accompanying drawings.

[0071] Please see Figure 1 and Figure 2 , Figure 1 This is a schematic diagram of the structure of an electronic device 1000 provided in an embodiment of this application. Figure 2 for Figure 1 The diagram shows a cross-sectional view of the electronic device 1000 along line II-II. This application provides an electronic device 1000, which includes a camera module 100, a device housing 200, and a screen 300. Both the camera module 100 and the screen 300 are disposed within the device housing 200. It should be noted that... Figure 1 The accompanying drawings below only schematically illustrate some components included in the electronic device 1000; the actual shape, size, location, and construction of these components are not subject to change. Figure 1And as specified in the accompanying figures below. Furthermore, when the electronic device 1000 is a device of other forms, the electronic device 1000 may not include the screen 300. For ease of description, the width direction of the electronic device 1000 is defined as the X-axis, the length direction as the Y-axis, and the thickness direction as the Z-axis. It is understood that the coordinate system of the electronic device 1000 can be flexibly set according to specific practical needs.

[0072] Electronic device 1000 can be a mobile phone, tablet personal computer, laptop computer, personal digital assistant (PDA), camera, personal computer, laptop computer, in-vehicle equipment, wearable device, augmented reality (AR) glasses, AR helmet, virtual reality (VR) glasses or VR helmet, or other devices with camera functions. Figure 1 The electronic device 1000 of the embodiment shown is illustrated using a mobile phone as an example.

[0073] The device housing 200 may include a frame 201 and a back cover 202. The back cover 202 is fixed to the frame 201. For example, the back cover 202 may be fixedly connected to the frame 201 by means of adhesive, snap-fit, or other methods. The back cover 202 may also be integrally formed with the frame 201, that is, the back cover 202 and the frame 201 are a single integral structure.

[0074] In some embodiments, screen 300 can be used to display images, etc. The display screen of screen 300 can be an organic light-emitting diode (OLED) display, or an active-matrix organic light-emitting diode (AMOLED) display, or a liquid crystal display (LCD), etc. Screen 300 can be located on the side of the bezel away from the back cover 202. In this case, screen 300 and back cover 202 can be located on opposite sides of bezel 201. Screen 300, bezel 201, and back cover 202 together form the interior of electronic device 1000. The interior of electronic device 1000 can be used to house components of electronic device 1000, such as batteries, motherboards, earpieces, speakers, gyroscopes, etc. Screen 300 can be a flat screen or a curved screen.

[0075] A camera module 100 is disposed inside an electronic device 1000. The camera module 100 may be located on the side of the screen 300 facing the rear cover 202. The rear cover 202 may have a light-transmitting portion 2021. The light-transmitting portion 2021 may be made of a transparent material, such as glass or plastic. Thus, light from outside the electronic device 1000 can pass through the light-transmitting portion 2021 and enter the interior of the electronic device 1000. The camera module 100 collects the light entering the interior of the electronic device 1000. The light-transmitting portion 2021 can be configured in various ways; for example, it may be a combination of a decorative element and the rear cover 202. This application does not specifically limit the structure of the light-transmitting portion 2021. The camera module 100 may be a rear-facing camera module 100 or a front-facing camera module 100. In this embodiment, the camera module 100 is described using a rear-facing camera module 100 as an example.

[0076] The camera module 100 includes a condenser lens 1, a first reflector 2, a focusing module 3, a second reflector 4, an image stabilization module 5, and a module bracket 6. The condenser lens 1, first reflector 2, focusing module 3, second reflector 4, and image stabilization module 5 are all mounted on the module bracket 6. The condenser lens 1 and first reflector 2 are arranged opposite each other along a first direction, and the first reflector 2 is used to change the optical axis parallel to the first direction to a second direction. The focusing module 3 includes a focusing lens group 31, which is located between the first reflector 2 and the second reflector 4 in the second direction, and the optical axis of the focusing lens group 31 is parallel to the second direction. The second reflector 4 is used to change the optical axis in the second direction to the first direction. The image stabilization module 5 includes an image sensor 51, which and the condenser lens 1 are located on opposite sides of the second reflector 4 along the first direction. Light emitted from the focusing lens group 31 is reflected once by the second reflector 4 before being emitted to the image sensor 51. The first and second directions intersect. The first direction can be the thickness direction of the electronic device 1000. The second direction can be perpendicular to the first direction, in which case the second direction can be the width direction of the electronic device 1000; the second direction may also not be perpendicular to the first direction.

[0077] By employing the folded optical path of the condenser lens 1, the first reflector 2, and the second reflector 4, the camera module 100 achieves telephoto imaging while maintaining a relatively small overall height and volume, resulting in a low-profile design. Furthermore, the image sensor 51 is located on the side of the second reflector 4 away from the condenser lens 1, reducing physical interference during assembly. This allows the photosensitive surface of the image sensor 51 to be larger than that of the condenser lens 1, eliminating the limitation on its size. Simultaneously, light emitted from the focusing lens group 31 only needs to be reflected once by the second reflector 4 before reaching the image sensor 51, minimizing reflections and improving image quality.

[0078] In one embodiment, the optical axis of the focusing and reflecting lens 1 (such as...) Figure 2 The optical axis A1 in the image is shown, and the optical axis of the first reflector 2 is shown (as shown in the image). Figure 2 The optical axis (as shown in A2) coincides with the optical axis of the focusing lens group 31 (as shown in A2). Figure 2 The optical axis A3 in the figure has a first included angle (as shown in Figure A3). Figure 2 As shown by angle α1 in the diagram, the value of the first included angle is greater than or equal to 84° and less than or equal to 96°. For example, the value of the first included angle can be 84°, 85°, 86°, 88°, 89°, 90°, 91°, 92°, 93°, 95°, or 96°, etc. This reduces interference with the mounting of the condenser lens 1 and reduces the overall shoulder height of the camera module 100. When the value of the first included angle is 90°, the first direction is perpendicular to the second direction. When the value of the first included angle is less than 90°, the optical axis emitted from the focusing lens group 31 can be tilted towards the condenser lens 1, and after passing through the second reflector 4, it can be changed to the side away from the condenser lens 1 along the first direction, which is beneficial to further reduce the shoulder height of the camera module 100.

[0079] The focusing and reflecting lens 1 can be a Cassegrain lens, which rapidly captures light from outside the camera module 100. The focusing and reflecting lens 1 can be composed of one or two lenses; when composed of two lenses, the two lenses are connected. The focusing and reflecting lens 1 includes a first transmission surface 11, a first reflection surface 12, a second reflection surface 13, and a second transmission surface 14. The first transmission surface 11 and the second reflection surface 13 are located on the object-side surface of the focusing and reflecting lens 1, with the first transmission surface 11 surrounding the second reflection surface 13. The first reflection surface 12 and the second transmission surface 14 are located on the image-side surface of the focusing and reflecting lens 1, with the first reflection surface 12 surrounding the second transmission surface 14. Light from outside the camera module 100 passes sequentially through the first transmission surface 11, the first reflection surface 12, the second reflection surface 13, and the second transmission surface 14 before being transmitted to the first reflector 2.

[0080] In one embodiment, the first transmissive surface 11 and the second reflective surface 13 are arranged opposite to the light-transmitting part. Light from outside the camera module 100 passes through the light-transmitting part and is incident and refracted at the first transmissive surface 11. After being reflected sequentially by the first reflective surface 12 and the second reflective surface 13, it is refracted and emitted at the second transmissive surface 14. After multiple reflections within the focusing and reflecting lens 1, the light is emitted to the focusing lens group 31. The focusing lens group 31 focuses and adjusts the light, thereby increasing the focal length of the camera module 100 from less than 100mm to 300mm and the EPD of the camera module 100 from 8-10mm to 16mm, achieving a long focal length and large aperture shooting effect.

[0081] In one embodiment, the first reflecting surface 12 is an annular spherical surface or an annular aspherical surface, and the second reflecting surface 13 is a circular spherical surface or a circular aspherical surface. The first transmitting surface 11 and the second transmitting surface 14 can both be circular spherical surfaces, with the first transmitting surface 11 recessed towards the first reflecting surface 12 and the second transmitting surface 14 recessed towards the second reflecting surface 13.

[0082] Please combine Figure 2 , Figure 3 and Figure 4 , Figure 3 This is a schematic diagram of the structure of a camera module 100 provided in an embodiment of this application. Figure 4 This is an exploded structural diagram of a focusing and reflecting lens 1 and a first base 61 provided in one embodiment of this application. In one embodiment, the module bracket 6 includes a first base 61, which is used to mount the focusing and reflecting lens 1. The first base 61 encloses a first mounting space 611, which is used to accommodate the focusing and reflecting lens 1. For example, the first base 61 has a cylindrical structure. The first mounting space 611 has openings on both opposite sides in a first direction. The first transmissive surface 11 and the second reflective surface 13 are located at the opening of the first mounting space 611 on the side away from the first reflector 2 in the first direction. The first reflective surface 12 and the second transmissive surface 14 are located at the opening of the first mounting space 611 on the side facing the first reflector 2 in the first direction. The inner wall surface of the first base 61 is adapted to the side surface of the focusing and reflecting lens 1. For example, the side surface of the focusing and reflecting lens 1 is an annular surface, and the side surface of the focusing and reflecting lens 1 is precisely positioned with the inner wall surface of the first base 61 by means of a circular chamfer. The first base 61 and the focusing and reflecting lens 1 can be connected and fixed by means of bonding, and the thickness of the adhesive bonding can be controlled between 100μm and 500μm to ensure the bonding strength.

[0083] Please combine Figure 5 , Figure 5This is an exploded structural diagram of a focusing telescope lens 1, a first reflector 2, and a first base 61 provided in another embodiment of this application. In one embodiment, the module bracket 6 includes a first base 61, which is used to mount the focusing telescope lens 1 and the first reflector 2. The first base 61 has a first mounting space 611 and a second mounting space 612 that are connected. The first mounting space 611 is used to mount the focusing telescope lens 1, and the second mounting space 612 is used to mount the first reflector 2. Fixing the focusing telescope lens 1 and the first reflector 2 to the same base can reduce the relative displacement between the focusing telescope lens 1 and the first reflector 2 caused by external vibration or impact, ensuring long-term alignment of the optical path, thereby guaranteeing the imaging quality of the camera module 100. The outer peripheral surface of the focusing telescope lens 1 can be connected and fixed to the peripheral surface of the first base 61 by means of bonding or other methods. The side of the focusing telescope lens 1 is precisely positioned with the inner wall surface surrounding the first mounting space 611 by means of a circular cut edge. The first reflector 2 can also be connected and fixed to the inner wall surface that forms the second installation space 612 by means of adhesive bonding or other methods.

[0084] The first reflector 2 includes a first incident surface 21, a third reflecting surface 22, and a first exiting surface 23. The first incident surface 21 is disposed opposite to the second transmission surface 14. The third reflecting surface 22 is connected between the first incident surface 21 and the first exiting surface 23. The third reflecting surface 22 is disposed at a preset angle to the first exiting surface 23. The third reflecting surface 22 is used to change the direction of light from the first incident surface 21 to a second direction and illuminate the first exiting surface 23. The first exiting surface 23 is disposed opposite to the image side of the focusing lens group 31.

[0085] The first reflector 2 can be a triangular prism. Both the first incident surface 21 and the first exit surface 23 can be curved surfaces or flat surfaces. The first exit surface 23 and the third reflecting surface 22 have a second included angle (e.g., ...). Figure 5As shown in angle α2), the value of the second included angle is greater than or equal to 42° and less than or equal to 48°. For example, the value of the second included angle is 42°, 43°, 44°, 45°, 46°, 47°, or 48°. In this way, the light emitted from the first emitting surface 23 can be tilted towards the focusing and reflecting lens 1 in the first direction, which helps to reduce the overall height of the camera module 100 and realize the small volume design of the camera module 100. Among them, when the first emitting surface 23 is a plane, the second included angle between the first emitting surface 23 and the third reflecting surface 22 is: the angle formed by the side of the first emitting surface 23 and the side of the third reflecting surface 22 in the cross section obtained by the first reflector 2 along line VI-VI, where the side of the first emitting surface 23 and the side of the third reflecting surface 22 intersect and are located on the same side of the first reflector 2. When the first emitting surface 23 is curved, the angle formed by the tangents at the endpoints of the side of the first emitting surface 23 and the side of the third reflecting surface 22 in the cross section obtained along line VI_VI of the first reflector 2 is such that the side of the first emitting surface 23 intersects the side of the third reflecting surface 22 and is located on the same side of the first reflector 2.

[0086] Please see Figure 2 and Figure 6 , Figure 6 for Figure 3 The diagram shows a cross-sectional view of the camera module 100 along line VI-VI. The module bracket 6 also includes a second base 62 for mounting the focusing lens group 31. The second base 62 and the first base 61 can be connected and fixed by adhesive bonding.

[0087] Please combine Figure 7 , Figure 7 This is a schematic diagram of a second base 62 and a focusing module 3 provided in one embodiment of this application. When only the condenser lens 1 is mounted on the first base 61, the second base 62 has a connected second mounting space 612 and a third mounting space 621. The second mounting space 612 is used to mount the first reflector 2, and the third mounting space 621 is used to mount the focusing lens group 31. In other words, the first reflector 2 and the focusing lens group 31 are fixed in the second base 62. This reduces the relative displacement between the focusing lens group 31 and the first reflector 2 caused by external vibrations or impacts, ensuring long-term alignment of the optical path and improving the focusing accuracy of the camera module 100.

[0088] Please combine Figure 8 , Figure 8 This is a schematic diagram of another second base 62 and focusing module 3 provided in an embodiment of this application. When the condenser lens 1 and the first reflector 2 are installed on the first base 61, the second base 62 and the first reflector 2 are arranged along a second direction. The second base 62 has a third mounting space 621, which is used to install the focusing lens group 31.

[0089] Please see Figure 9 , Figure 9 for Figure 7 The diagram shows an exploded view of the second base 62, the first housing 63, and the focusing module 3. The second base 62 also includes a first guide groove 622 and a guide member 623. There are two first guide grooves 622, spaced apart, with each first guide groove 622 corresponding to a guide member 623, which is fixed within the first guide groove 622. The guiding directions of both the first guide groove 622 and the guide member 623 are parallel to a second direction, allowing the focusing lens assembly 31 to move along the second direction under the guidance of the guide member 623 and the first guide groove 622.

[0090] The second base 62 includes a bottom wall 624, a first side wall 625, a second side wall 626, and a third side wall 627. The first side wall 625, second side wall 626, and third side wall 627 are sequentially connected to the edge of the bottom wall 624 facing the focusing and reflecting lens 1 along a first direction. That is, the top of the second base 62 has an opening, and the opening at the top of the second base 62 is opposite to the first mounting space 611 enclosed by the first base 61. The second side wall 626 is located at the edge of the bottom wall 624 facing the first reflector 2 along a second direction, and the second side wall 626 has a light inlet 6261, which is opposite to the first exit surface 23 of the first reflector 2. The bottom wall 624, first side wall 625, second side wall 626, and third side wall 627 together enclose the third mounting space 621.

[0091] like Figure 9 As shown, in an embodiment where the second base 62 includes a second mounting space 612, the second base 62 further includes a connecting wall 628. The connecting wall 628 is disposed on the side of the second side wall 626 facing the first reflector 2. The connecting wall 628 forms the second mounting space 612, and the shape of the connecting wall 628 is adapted to the shape of the first reflector 2.

[0092] The module bracket 6 also includes a first housing 63, which covers the second base 62. Specifically, the first housing 63 houses the second base 62, and the focusing lens assembly 31 within the second base 62 is also housed within the first housing 63. The first housing 63 reduces stray light entering the focusing lens assembly 31. The side of the first housing 63 facing the condenser lens 1 along a first direction has a first notch 6311, at least a portion of which connects the first mounting space 611 and the third mounting space 621. The first notch 6311 avoids the condenser lens 1 within the first mounting space 611. At least a portion of the first reflective surface 12 of the condenser lens 1 can extend through the first notch 6311 into the first housing 63, reducing the shoulder height of the camera module 100. Simultaneously, it improves the space utilization of the first housing 63, facilitating a compact design for the camera module 100.

[0093] The first housing 63 includes a first top wall 631, a fourth side wall 632, a fifth side wall 633, and a sixth side wall 635. The first top wall 631 is disposed opposite to the bottom wall 624 of the second base 62. A first notch 6311 is provided on the edge of the first top wall 631 facing the first reflector 2. The fourth side wall 632, the fifth side wall 633, and the sixth side wall 635 are sequentially connected to the edge of the first top wall 631 facing the bottom wall 624. The fourth side wall 632 is located on the side of the first side wall 625 away from the third side wall 627, and the sixth side wall 635 is located on the side of the third side wall 627 away from the first side wall 625. In this way, the fourth side wall 632 and the sixth side wall 635 can further block external stray light from entering the focusing lens group 31. The fifth sidewall 633 and the second sidewall 626 are arranged opposite each other along the second direction. The fifth sidewall 633 is provided with a light outlet 6331. The light outlet 6331 and the image side of the focusing lens group 31 are arranged opposite each other along the second direction. The light emitted from the focusing lens group 31 illuminates the second reflector 4 after passing through the light outlet 6331.

[0094] like Figure 9 As shown, when only the focusing lens group 31 is installed on the second base 62, the first notch 6311 on the first top wall 631 is semi-circular and is adapted to the first reflecting surface 12 located inside the first housing 63.

[0095] like Figure 10 As shown, Figure 10 for Figure 8The diagram shows an exploded view of the second base 62, the first housing 63, and the focusing module 3. With the first reflector 2 and the focusing lens group 31 mounted on the second base 62, the first notch 6311 on the first top wall 631 is circular. The first notch 6311 avoids the second transmission surface 14 and part of the first reflection surface 12 of the focusing and reflecting lens 1, allowing light emitted from the second transmission surface 14 to enter the first reflector 2 through the first notch 6311. Simultaneously, the first notch 6311 avoids part of the first reflection surface 12, allowing a portion of the first reflection surface 12 to extend into the first housing 63 through the first notch 6311, reducing the overall shoulder height of the camera module 100.

[0096] The focusing lens group 31 includes a first lens group 311 and a second lens group 312, with the first lens group 311 disposed between the first reflector 2 and the second lens group 312. The first lens group 311 may include one or more lenses. When the first lens group 311 includes multiple lenses, the multiple lenses are arranged along a second direction, and the optical axes of the multiple lenses overlap and are parallel to the second direction. The second lens group 312 may also include one or more lenses, with the multiple lenses arranged along the second direction, and the optical axes of the multiple lenses overlap and are parallel to the second direction.

[0097] Please combine Figure 6 and Figure 11 , Figure 11 This is a cross-sectional structural diagram of another camera module 100 provided in one embodiment of this application. In one embodiment, the module bracket 6 further includes a first carrier 64, which is installed in a third mounting space 621. The first carrier 64 and the first reflector 2 are arranged along a second direction, and the first carrier 64 is used to fix at least one of the first lens group 311 and the second lens group 312. Figure 11 As shown, when both the first lens group 311 and the second lens group 312 are fixed to the first carrier 64, the focusing module 3 is a single-group focusing module 3; as Figure 6 As shown, when one of the first lens group 311 and the second lens group 312 is fixed on the first carrier 64, the first lens group 311 and the second lens group 312 are arranged in groups, and the focusing module 3 is a group focusing module 3. The focusing module 3 also includes a focusing drive mechanism 32 and a focusing flexible circuit board 33. A portion of the focusing drive mechanism 32 is installed in the third mounting space 621, and the focusing drive mechanism 32 is used to drive the first carrier 64 to move relative to the second base 62 in a second direction. A portion of the focusing flexible circuit board 33 is located in the first housing 63 and is electrically connected to the focusing drive mechanism 32.

[0098] Specifically, the first carrier 64 is provided with a second guide groove 641 on the side facing the second base 62. The second guide groove 641 is arranged opposite to the first guide groove 622. The second guide groove 641 is used to cooperate with the guide member 623. When the focusing drive mechanism 32 drives the first carrier 64 to move, the first carrier 64 moves along the second direction under the guidance of the first guide groove 622, the second guide groove 641 and the guide member 623. The focusing lens group 31 follows the first carrier 64 and moves along the second direction.

[0099] The first carrier 64 moves along the second direction within the space between the second sidewall 626 and the fifth sidewall 633, wherein the portion of the second sidewall 626 without a light inlet 6261 and the portion of the fifth sidewall 633 without a light outlet 6331 can limit the first carrier 64 in the second direction to prevent the first carrier 64 from sliding out of the light outlet 6331 or the light inlet 6261 along the second direction.

[0100] Please combine Figure 12 , Figure 12 for Figure 6 The enlarged view of XII in the camera module 100 shown. The first carrier 64 includes a first surface 642 and a second surface 643 disposed opposite to each other. At least one of a first lens group 311 and a second lens group 312 is disposed between the first surface 642 and the second surface 643. The first surface 642 is closer to the condenser lens 1 in a first direction than the second surface 643. When a portion of the first reflective surface 12 of the condenser lens 1 extends into the first housing 63, the minimum distance between the edge of the first surface 642 toward the first reflector 2 and the second reflective surface 13 (e.g., ...) is... Figure 12 The distance H shown is greater than or equal to 0.1 mm and less than or equal to 0.6 mm. For example, the minimum spacing can be 0.1 mm, 0.15 mm, 0.2 mm, 0.25 mm, 0.32 mm, 0.38 mm, 0.45 mm, 0.50 mm, 0.55 mm, or 0.6 mm, etc., and will not be listed one by one. As the first carrier 64 moves along the second direction under the drive of the focusing drive mechanism 32, when the first carrier 64 moves along the second direction, when the first carrier 64 moves to a certain position, there is a minimum distance between the edge of the first surface 642 facing the first reflector 2 and the second reflector 13 located in the third mounting space 621. The top of the second base 62 has an opening, and there are no other devices between the first reflector 12 located in the first housing 63 and the first surface 642. The minimum distance is controlled to be greater than or equal to 0.1 mm and less than or equal to 0.6 mm to avoid the first carrier 64 colliding with the first reflector 12 during the movement, and it is not easy to cause physical interference when assembling the first carrier 64 and the focusing and reflecting lens 1.

[0101] Please continue reading. Figure 9 and Figure 10The focusing drive mechanism 32 includes a focusing magnetic 321, a focusing coil 322, and a focusing sensor 323. The focusing magnetic 321 is fixed on the first carrier 64. The focusing coil 322 and the focusing sensor 323 are both fixed on the focusing flexible circuit board 33 and are electrically connected to the focusing flexible circuit board 33. The focusing flexible circuit board 33 integrates a focusing drive chip, and the input and output terminals of the focusing coil 322 can form a current loop with the focusing drive chip through the focusing flexible circuit board 33. The first carrier 64 is provided with a mounting slot 644 for accommodating the focusing magnetic 321. The first sidewall 625 is provided with a mounting hole 6251, which penetrates both opposite sides of the first sidewall 625, so that the mounting hole 6251 connects to the third mounting space 621. The mounting hole 6251 is used to accommodate the focusing coil 322. The focusing coil 322 can be arranged around the focusing sensor 323. The focusing sensor 323 can effectively utilize the space enclosed by the focusing coil 322. The arrangement of the focusing coil 322, the focusing magnetic 321 and the focusing sensor 323 can greatly improve the space utilization of the second base 62, which is conducive to realizing the small size design of the camera module 100.

[0102] The first housing 63 also includes a first through hole 634, which is disposed opposite to the light outlet 6331 along a third direction. The third direction is perpendicular to the second direction and intersects the first direction. When the second direction is perpendicular to the first direction, the second direction can be the X-axis direction, and the third direction can be the Y-axis direction. The first through hole 634 connects the interior and exterior of the first housing 63. A portion of the focusing flexible circuit board 33 is located inside the first housing 63 and mounted on the second base 62 to facilitate electrical connection with the focusing coil 322 fixed on the first sidewall 625 of the second base 62. A portion of the focusing flexible circuit board 33 passes through the first through hole 634 and is located outside the first housing 63.

[0103] The first through hole 634 can be located at the corner of the fourth side wall 632 and the fifth side wall 633, or the first through hole 634 can also be located at the corner of the fifth side wall 633 and the sixth side wall 635. The focusing flexible circuit board 33 extends out of the first housing 63 from the side of the first housing 63. Compared with the focusing flexible circuit board 33 extending out from the top or bottom of the first housing 63, the size of the focusing flexible circuit board 33 can be reduced, thereby reducing the space occupied by the focusing flexible circuit board 33 in the camera module 100. When the focusing flexible circuit board 33 extends out of the first housing 63 from the first through hole 634, it will not affect the light transmission at the light outlet 6331.

[0104] Please see Figure 13 and Figure 14 , Figure 13This is a schematic diagram of the structure of another camera module 100 provided in an embodiment of this application. Figure 14 for Figure 13 The diagram shows a cross-sectional view of the camera module 100 along line XIV-XIV. In one embodiment, a lens 7 is further provided between the focusing and reflecting lens 1 and the first reflector 2. The lens 7 is located between the second transmission surface 14 and the first incident surface 21. Light rays emitted from the second transmission surface 14 pass through the lens 7 and then enter the first incident surface 21. The lens 7 can be disposed within the first base 61, such as... Figure 14 As shown, lens 7 is disposed within the first mounting space 611 of the first base 61. The placement of lens 7 provides greater freedom and sensitivity in the optical design of the camera module 100, which is beneficial for improving image quality. In other embodiments, lens 7 may be disposed in the second mounting space 612, and the specific placement is not limited.

[0105] A light-shielding element 71 may be provided on the edge of the lens 7 facing the light-reflecting lens 1. The light-shielding element 71 can reduce stray light entering the lens 7.

[0106] The module bracket 6 also includes a second housing 65, which is connected and fixed to the first housing 63. For example, the second housing 65 and the first housing 63 can be connected and fixed by means of bonding, which can block external stray light from entering through the gap between the second housing 65 and the first housing 63. The second housing 65 is used to house the second reflector 4 and the image stabilization module 5.

[0107] The second housing 65 has a second through hole 6521 on the side facing the focusing and reflecting lens 1 in the first direction. The second through hole 6521 connects the interior of the second housing 65 and the exterior of the second housing 65.

[0108] Please combine Figure 15 and Figure 16 , Figure 15 This is a schematic diagram of the structure of the image stabilization module 5 in the camera module 100 provided in an embodiment of this application. Figure 16This is an exploded structural diagram of an image stabilization module 5 and a module bracket 6 provided in an embodiment of this application. The second housing 65 may include a bottom housing 651, a cover plate 652, and a protrusion 653. The top of the bottom housing 651 is connected to the cover plate 652, and the bottom housing 651 and the cover plate 652 can be connected and fixed by means of adhesive, welding, or screw fixing. The protrusion 653 is provided on the side of the cover plate 652 facing the focusing lens group 31. Part of the protrusion 653 extends into the space enclosed by the bottom housing 651, and part of the protrusion 653 protrudes from the side of the cover plate 652 facing away from the bottom housing 651. The protrusion 653 and the cover plate 652 can be an integrally formed structure to reduce the assembly between components. The cover plate 652 is provided with a second through hole 6521. A protrusion 653 is provided on the side of the plate facing the bottom shell 651. The protrusion 653 forms a receiving cavity 6531, and the receiving cavity 6531 is used to install the second reflector 4. The protrusion 653 and the second reflector 4 can be connected and fixed by means of adhesive bonding or the like.

[0109] The second reflector 4 can be a planar structure, that is, the second reflector 4 has a reflective surface, and the light emitted from the focusing lens group 31 is emitted to the image sensor 51 after passing through the reflective surface of the second reflector 4.

[0110] In this embodiment, the second reflector 4 can be a triangular prism, that is, the second reflector 4 includes a second incident surface 41, a fourth reflecting surface 42, and a second exiting surface 43. The second incident surface 41 and the image side of the focusing lens group 31 are arranged opposite to each other along the second direction. The fourth reflecting surface 42 is connected between the second incident surface 41 and the second exiting surface 43. The fourth reflecting surface 42 is used to reflect the light emitted from the second incident surface 41 to the second exiting surface 43. The second exiting surface 43 and the image sensor 51 are arranged opposite to each other along the first direction.

[0111] For example, the protrusion 653 includes a second top wall 6532, a first baffle 6533, a second baffle 6534, and a third baffle 6535. The second top wall 6532 is located on the side of the cover plate 652 facing away from the bottom shell 651. The first baffle 6533, the second baffle 6534, and the third baffle 6535 are sequentially connected to the edge of the second top wall 6532 facing the cover plate 652. Parts of the first baffle 6533, the second baffle 6534, and the third baffle 6535 all extend into the space enclosed by the bottom shell 651. The first baffle 6533 and the third baffle 6535 are arranged opposite each other. The second baffle 6534 is inclined at the edge of the second top wall 6532 away from the focusing lens group 31 along the second direction. The second baffle 6534 is arranged facing the fourth reflecting surface 42 of the second reflector 4. The second top wall 6532, the first baffle wall 6533, the second baffle wall 6534, and the third baffle wall 6535 together form a receiving cavity 6531. An opening is formed on the opposite side of the third baffle wall 6535, facing the focusing lens assembly 31 in a second direction. The second incident surface 41 of the second reflector 4 is located at this opening, allowing light emitted from the focusing lens assembly 31 to pass through the opening and illuminate the second incident surface 41. The second top wall 6532 is disposed opposite to the second exit surface 43 of the second reflector 4, and an opening is also formed on the opposite side of the second top wall 6532, allowing light emitted from the second exit surface 43 to exit through the opening and reach the image sensor 51. In this embodiment, the protrusion 653 covers the outside of the second reflector 4 and does not obstruct the transmission of light emitted from the focusing lens assembly 31. The protrusion 653 can also block other stray light within the bottom shell 651, reducing stray light entering the second reflector 4 and improving image quality.

[0112] In one embodiment, the inner wall surface of the second housing 65 facing the second reflector 4 is provided with a plurality of protrusions 6536, which are located on the object side of the second reflector 4 facing the focusing lens group 31. Specifically, at least one of the second top wall 6532, the first baffle wall 6533, and the third baffle wall 6535 is provided with a plurality of protrusions 6536, and along the second direction, the plurality of protrusions 6536 are located on the side of the second incident surface 41 of the second reflector 13 facing the focusing lens group 31. In other words, the plurality of protrusions 6536 are closer to the focusing lens group 31 than the second incident surface 41 in the second direction. The plurality of protrusions 6536 can be achieved by grooving the inner wall surface of the protrusion 653. The plurality of protrusions 6536 make the inner wall surface of the protrusion 653 have an uneven texture, causing external stray light to scatter in random directions, reducing the light intensity in a specific direction, thereby reducing the possibility of entering the main optical path.

[0113] Please see Figure 16 or Figure 17 , Figure 17This is an exploded view of another image stabilization module 5 and module bracket 6 provided in an embodiment of this application. The image stabilization module 5 also includes a module circuit board 52, an image stabilization drive mechanism 53, and a movable flexible circuit board 54. The module circuit board 52 is electrically connected to external devices of the camera module 100 (such as the host circuit board of the electronic device 1000). The module circuit board 52 is also electrically connected to the focusing flexible circuit board 33 and the movable flexible circuit board 54. The movable flexible circuit board 54 is connected to the image stabilization drive mechanism 53 and the image sensor 51. The image stabilization drive mechanism 53 drives the movable flexible circuit board 54 to move, thereby moving the image sensor 51 connected to the movable flexible circuit board 54.

[0114] Part of the module circuit board 52 is housed inside the second housing 65, and part of the module circuit board 52 passes through the second through hole 6521 outside the second housing 65 and is electrically connected to the focusing flexible circuit board 33 located outside the first housing 63.

[0115] Please combine Figure 16 and Figure 18 , Figure 18This is a partial structural schematic diagram of the second housing 65 provided in one embodiment of this application. In one embodiment, the module circuit board 52 includes a first circuit board 521 and a first flexible circuit board 522. The first circuit board 521 and the movable flexible circuit board 54 are arranged at intervals along a first direction. One end of the first circuit board 521 is connected to the first flexible circuit board 522. The first flexible circuit board 522 and the second reflector 4 are arranged at intervals along a third direction. The first flexible circuit board 522 extends out of the second housing 65 through the second through hole 6521 to be electrically connected to the focusing flexible circuit board 33 located outside the first housing 63. For example, the first flexible circuit board 522 and a portion of the focusing flexible circuit board 33 located in the second housing 65 are stacked and electrically connected by welding, so that the module circuit board 52 and the focusing flexible circuit board 33 transmit electrical signals and position signals to achieve focus control. The connection between the module circuit board 52 and the focusing flexible circuit board 33 is simple and easy to implement. Furthermore, the connection point between the module circuit board 52 and the focusing flexible circuit board 33 is located outside the first housing 63 and the second housing 65, which reduces the space occupied inside the first housing 63 and the second housing 65, facilitating a compact design for the camera module 100. The first flexible circuit board 522 does not affect the transmission of light incident on the second reflector 4. It can be understood that the first flexible circuit board 522 is bent to facilitate its connection with the focusing flexible circuit board 33 outside the first housing 63 via the second through hole 6521. The second through hole 6521 is located on the cover plate 652 on the side of the third baffle 6535 of the protrusion 653 away from the first baffle 6533. The first flexible circuit board 522 and the focusing flexible circuit board 33 located outside the first housing 63 are also located on the side of the third baffle 6535 away from the first baffle 6533. In this way, the size of the focusing flexible circuit board 33 located outside the first housing 63 can be shortened.

[0116] The first circuit board 521 integrates an image stabilization drive circuit 5211. The first circuit board 521 can be connected and fixed to the movable flexible circuit board 54 and electrically connected. The first circuit board 521 can also be electrically connected to external devices of the camera module 100. In this way, the focusing flexible circuit board 33 and the movable flexible circuit board 54, which are electrically connected to the module circuit board 52, can transmit signals to each other with external devices.

[0117] The module support 6 also includes a second carrier 66, which is fixed inside the second housing 65 and used to support the module circuit board 52. Specifically, the first circuit board 521 is fixed to one side of the second carrier 66 to ensure the stability of the module circuit board 52 installation. The portion of the movable flexible circuit board 54 connected to the first circuit board 521 can also be supported on the second carrier 66 to ensure the stability of the connection between the movable flexible circuit board 54 and the first circuit board 521.

[0118] Please combine Figure 19 , Figure 19 This is a schematic diagram illustrating the connection between the focusing module 3 and the image stabilization module 5 according to an embodiment of this application. In one embodiment, the second housing 65 has a first positioning part 654 on the side facing away from the second circuit board 523, and the first flexible circuit board 522 has a first positioning hole 5221. The first positioning hole 5221 and the first positioning part 654 are connected in a cooperative manner (e.g., the first positioning part 654 passes through the first positioning hole 5221) to limit the first flexible circuit board 522. The focusing flexible circuit board 33 located outside the first housing 63 extends onto the second housing 65 and is stacked on the first flexible circuit board 522 located outside the second housing 65, so that this part of the focusing flexible circuit board 33 is electrically connected to the first flexible circuit board 522. Furthermore, the second housing 65 is provided with a second positioning part 655 on the side opposite to the first circuit board 521. The focusing flexible circuit board 33 on the second housing 65 is provided with a second positioning hole 331. The second positioning hole 331 is connected to the second positioning part 655 (e.g., the second positioning part 655 passes through the second positioning hole 331) to limit the focusing flexible circuit board 33.

[0119] Please continue reading. Figure 16 or Figure 17 The module bracket 6 also includes a stabilization bracket 67, which is housed within the second housing 65 and fixed to the movable circuit board. The stabilization bracket 67 can move with the movement of the movable circuit board. The stabilization drive mechanism 53 includes a stabilization magnet 531, a stabilization coil 532, and a stabilization sensor 533. One of the stabilization magnet 531 and the stabilization coil 532 is fixed to the stabilization bracket 67, and the other is fixed to the first circuit board 521. The stabilization sensor 533 can be disposed within the space enclosed by the stabilization coil 532, effectively utilizing the space enclosed by the stabilization coil 532 and improving the space utilization of the stabilization drive mechanism 53 within the second housing 65. The first circuit board 521 is fixed to the second carrier 66.

[0120] Please combine Figure 17 and Figure 20 , Figure 20 for Figure 17The diagram shows a partially exploded view of the anti-shake module 5. In one embodiment, the anti-shake magnetic 531 is fixed to the anti-shake bracket 67, and the anti-shake coil 532 is fixed to the second carrier 66. The anti-shake coil 532 is used to cooperate with the anti-shake magnetic 531 when energized to drive the movable flexible circuit board 54 to move relative to the second carrier 66 in a plane perpendicular to the first direction, thereby driving the anti-shake bracket 67 on the movable flexible circuit board 54 to move. At this time, the anti-shake drive mechanism 53 is a moving magnet type anti-shake drive mechanism 53. When the image stabilization drive mechanism 53 is a moving magnet type image stabilization drive mechanism 53, the module circuit board 52 may also include a second circuit board 523 and a second flexible circuit board 524. The second circuit board 523 and the first circuit board 521 are opposite sides of the second carrier 66. The second circuit board 523 is electrically connected to the first circuit board 521 through the second flexible circuit board 524. At this time, the image stabilization coil 532 and the image stabilization sensor 533 can be directly electrically connected to the second circuit board 523 to be electrically connected to the image stabilization drive circuit 5211 on the first circuit board 521, and fixed on the second carrier 66 through the second circuit board 523.

[0121] Please see Figure 16 and Figure 21 , Figure 21 for Figure 16 The diagram shows a cross-sectional view of the image stabilization module 5. In one embodiment, the image stabilization coil 532 is fixed to the image stabilization bracket 67, and the image stabilization magnetic component 531 is fixed to the second carrier 66. The image stabilization coil 532 can be electrically connected to the image stabilization drive circuit 5211 on the module circuit board 52 via the movable flexible circuit board 54. When energized, the image stabilization coil 532 cooperates with the image stabilization magnetic component 531 to drive the movable flexible circuit board 54 to move relative to the second carrier 66 in a plane perpendicular to the first direction, thereby driving the image stabilization bracket 67 on the movable flexible circuit board 54 to move. At this time, the image stabilization drive mechanism 53 is a moving coil image stabilization drive mechanism 53.

[0122] In summary, the camera module 100 provided in this application can be a super telephoto camera module 100 composed of a Cassegrain-type condenser lens 1, a first reflector 2 whose first incident surface 21 and first exit surface 23 are both planar, a grouped focusing lens group 31, and a moving magnet type image stabilization drive mechanism 53. Figure 6 As shown. The camera module 100 can also be a super telephoto camera module 100 composed of a Cassegrain-type condenser lens 1, a first reflector 2 in which one of the first incident surface 21 and the first exit surface 23 is curved, a single-group focusing lens group 31, and a dynamic image stabilization drive mechanism 53, as shown. Figure 11As shown. The camera module 100 can also be a super telephoto camera module 100 composed of a Cassegrain-type condenser lens 1, a lens 7, a first reflector 2 with a first incident surface 21 and a first exit surface 23 both being planar, a grouped focusing lens group 31, and a moving magnet type image stabilization drive mechanism 53, such as Figure 14 As shown. The camera module 100 can also be a super telephoto camera module 100 composed of a Cassegrain-type condenser lens 1, a first reflector 2 whose first incident surface 21 and first exit surface 23 are both flat, a group of focusing lens groups 31 arranged in groups, and a moving-coil image stabilization drive mechanism 53, etc.

[0123] For example, in the above embodiment, the anti-shake drive mechanism 53 may have two sets of anti-shake magnetic components 531 and anti-shake coils 532. One set of anti-shake magnetic components 531 and anti-shake coils 532 can be used to drive the movable flexible circuit board 54 to move relative to the second carrier 66 in a second direction, and the other set of anti-shake magnetic components 531 and anti-shake coils 532 can be used to drive the movable flexible circuit board 54 to move relative to the second carrier 66 in a third direction.

[0124] In other embodiments, the anti-shake drive mechanism 53 may include three sets of anti-shake magnetic components 531 and anti-shake coils 532. One set of anti-shake magnetic components 531 and anti-shake coils 532 is used to drive the movable flexible circuit board 54 to move relative to the second carrier 66 in a second direction. Another set of anti-shake magnetic components 531 and anti-shake coils 532 is used to drive the movable flexible circuit board 54 to move relative to the second carrier 66 in a third direction. Finally, another set of anti-shake magnetic components 531 and anti-shake coils 532 is used to drive the movable flexible circuit board 54 to tilt relative to the first direction.

[0125] It is understood that the image sensor 51 is fixedly connected to the movable flexible circuit board 54. When the movable flexible circuit board 54 moves relative to the image stabilization bracket 67 in a plane perpendicular to the first direction, the image sensor 51 can also move relative to the image stabilization bracket 67 in a plane perpendicular to the first direction, thereby achieving fine image stabilization for ultra-telephoto lenses.

[0126] In one embodiment, the image stabilization module 5 further includes a filter 55, which is disposed between the image side of the second reflector 4 and the image sensor 51. Light emitted from the second reflector 4 passes through the filter 55 and then illuminates the image sensor 51. The module bracket 6 further includes a mounting bracket 68, which is fixed to the flexible circuit board 54 and used to mount the filter 55. Thus, when the flexible circuit board 54 moves relative to the image stabilization bracket 67 in a plane perpendicular to the first direction, or tilts relative to the first direction, the mounting bracket 68 and the filter 55 can also move relative to the image stabilization bracket 67 in a plane perpendicular to the first direction.

[0127] The flexible circuit board 54 includes a first connecting portion 541, a second connecting portion 542, and a third connecting portion 543. The first connecting portion 541 is used to connect and fix with the image sensor 51 and the mounting bracket 68. The planes containing the first connecting portion 541 and the third connecting portion 543 are both parallel to a plane perpendicular to a first direction. A chip circuit is integrated on the first connecting portion 541, which is used to connect and fix with the image sensor 51 to achieve electrical connection between the flexible circuit board 54 and the image sensor 51. The second connecting portion 542 connects the first connecting portion 541 and the third connecting portion 543. When the second direction is perpendicular to the first direction, a portion of the plane containing the second connecting portion 542 is parallel to the first direction. The second connecting portion 542 can be located at one or more edges of the first connecting portion 541. The third connecting part 543 is used to connect and fix with the first circuit board 521 to realize the electrical connection between the movable flexible circuit board 54 and the module circuit board 52. Since the first circuit board 521 is electrically connected to the external devices of the camera module 100, the image sensor 51 on the movable flexible circuit board 54 and the external devices can transmit signals to each other.

[0128] In this application, the image stabilization module 5 enables optical image stabilization of the image sensor 51, which helps maintain a low shoulder height while ensuring the imaging quality of the camera module 100 and easily achieving characteristics such as long exposure. The above embodiments are only used to illustrate the technical solutions of this application and are not intended to limit it; although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this application.
