Description

Technical Field

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

[0002] Electronic devices typically incorporate camera modules to meet the needs of capturing images or videos. To balance the requirements of ultra-thin designs and telephoto shooting in electronic devices, periscope camera modules are widely used. A periscope camera module includes a camera assembly, which in turn includes a drive assembly and a prism. The drive assembly rotates the prism in two directions to adjust the optical path, thereby achieving optical image stabilization. However, when adjusting the prism's position, interference often occurs between the two directions, making adjustment difficult and, in severe cases, affecting the quality of the image or video. Summary of the Invention

[0003] The purpose of this application is to provide a camera assembly with relatively high adjustment accuracy. Another purpose of this application is to provide a camera module and electronic device including the above-described camera assembly.

[0004] This application provides a camera component, including: A prism has an input surface and an output surface; A first mounting body, wherein the prism is mounted on the first mounting body; The second mounting body and the first rotating shaft, wherein the first mounting body is rotatably supported on the second mounting body by the first rotating shaft, the axis of the first rotating shaft is parallel to the light-gathering surface, and the axis of the first rotating shaft is a first direction; The base and the second rotating shaft, the second mounting body is rotatably supported on the base through the second rotating shaft, the axis of the second rotating shaft is parallel to the light-emitting surface, and the axis of the second rotating shaft is the second direction; A first driving component is used to drive the first mounting body to rotate relative to the second mounting body around the first rotating shaft; The second driving component is used to drive the second mounting body to rotate relative to the base around the second rotating shaft.

[0005] In this embodiment, a first rotating shaft is connected between a first mounting body and a second mounting body. A first driving component drives the first mounting body to rotate around the first rotating shaft, thereby rotating the prism around a first direction. A second rotating shaft is connected between the second mounting body and the base. A second driving component drives the second mounting body to rotate around the second rotating shaft, thereby rotating the prism around a second direction. This allows the first mounting body to be driven to rotate around the first rotating shaft, or / and the second mounting body to be driven to rotate around the second rotating shaft, based on the direction and angle of vibration of the electronic device, to compensate for the amount of vibration of the electronic device. Because the first and second rotating shafts are separately configured, the prism's rotation adjustment around the first and second directions does not interfere with each other, improving the adjustment accuracy of the camera assembly and simplifying control.

[0006] In one example, the second mounting body includes a first sidewall and a second sidewall. The space between the first and second sidewalls is used to mount the first mounting body. A first rotating shaft passes through the first mounting body and includes two end segments, which are rotatably supported by the first and second sidewalls, respectively. In this way, the first mounting body is rotatably supported by the two ends of the same first rotating shaft, respectively, against the first and second sidewalls. By ensuring the machining accuracy of the first rotating shaft, the coaxiality of the rotation between the first and second mounting bodies and their sidewalls can be achieved, which is beneficial for improving the quality of the camera assembly.

[0007] In one example, the system further includes two first bushings, which are respectively fixed to a first sidewall and a second sidewall. Each first bushing has a first mounting hole on its surface facing the first rotating shaft, and the end shaft segment is rotatably mounted in the first mounting hole. This reduces the machining difficulty of the first and second sidewalls, and allows the first bushings to be made of a different material than the second mounting body. For example, using a high-strength metal for the first bushings improves the wear resistance of both the first bushing and the first rotating shaft.

[0008] In one example, the first mounting hole is a through hole, and the camera assembly also includes baffles. Each first bushing has a baffle fixed to its sidewall opposite to the first rotating shaft to block the first mounting hole, and the first rotating shaft is located between two baffles. Making the first mounting hole a through hole improves the concentricity of the first bushings.

[0009] In one example, the hardness of the baffle material is greater than that of the first bushing material. The baffle material can be stainless steel, and the first bushing can be copper with good wear resistance. The high hardness of the baffle material can improve the overall impact resistance of the camera assembly.

[0010] In one example, the first driving component includes a first magnet assembly and a first electromagnetic coil. The first magnet assembly is located on a first mounting body, and the first electromagnetic coil is mounted on a base; alternatively, the first magnet assembly is located on the base, and the first electromagnetic coil is mounted on the first mounting body. The force driving the rotation of the first mounting body is provided through the cooperation of the coil and the magnet. The structure is relatively simple, and the current flowing through the coil is controllable, offering high adjustment flexibility and precision. Furthermore, in this example, either the first magnet assembly or the first electromagnetic coil is mounted on the base, facilitating installation.

[0011] In one example, the first magnet assembly and the first electromagnetic coil are arranged along a third direction, and a first opening along a third direction is formed between the first sidewall and the second sidewall of the second mounting body. The first magnet assembly and the first electromagnetic coil are located between the first sidewall and the second sidewall, wherein the third direction is perpendicular to the light-emitting surface. In this embodiment, there is no intermediate obstruction between the first magnet assembly and the first electromagnetic coil, which minimizes the impact on the magnetic field strength generated by the first electromagnetic coil and facilitates the generation of a driving force that meets the rotation adjustment requirements with a smaller volume.

[0012] The first magnet assembly and the first electromagnetic coil are respectively mounted on the opposing surfaces of the first mounting body and the base. The first electromagnetic coil is mounted on the base for easy connection to the flexible circuit board.

[0013] In one example, the second mounting body further includes a connecting wall connected between the first and second side walls. The connecting wall is located on the side of the first side wall facing away from the light-receiving surface. The connecting wall rotatably supports the base via a second pivot and is movably supported by the base. This structure of the second mounting body is simple and relatively lightweight.

[0014] In one example, the first mounting body has a first cavity on its first surface facing away from the light-receiving surface, and a first protrusion on its connecting wall. The first protrusion is at least partially located inside the first cavity, and the second rotating shaft is at least partially disposed on the first protrusion. The first cavity can provide clearance space for the installation of the first protrusion, which is beneficial to reducing the size of the camera assembly along the first direction. Furthermore, the second rotating shaft being disposed on the first protrusion can improve the strength of the connection between the second mounting body and the second rotating shaft.

[0015] In one example, the second surface of the connecting wall facing away from the first mounting body has a second cavity, and the base has a second protrusion, with the second protrusion at least partially located in the second cavity. The other end of the second rotating shaft is connected to the second protrusion. In this embodiment, the second protrusion is provided at the location where the second rotating shaft is located on the base. The second protrusion has a relatively large thickness, which can improve the strength of the location where the second rotating shaft is located. Furthermore, the second cavity is provided on the surface of the second mounting body opposite to the second protrusion, which can provide installation space for the second protrusion, thus balancing the aspects of strength, reliability, and small size.

[0016] In one example, the first protrusion and the second protrusion are provided with coaxial through holes, and a second bushing is fixed inside each through hole. The two ends of the second rotating shaft are respectively installed on the two second bushings. The second bushings are machined independently of the second mounting body and the base, which helps to reduce the difficulty of machining the through holes. Furthermore, the second bushings can be made of different materials than the second mounting body and the base, thereby improving the wear resistance of the rotating connection position.

[0017] In one example, at least one ferromagnetic object is also included, mounted on the base. The ferromagnetic object and the first electromagnetic coil are located on the same side of the base. The first magnet assembly is also used to cooperate with the ferromagnetic object to generate a force that returns the first mounting body to its initial mounting position. A force can always exist between the first magnet assembly and the ferromagnetic object; for example, the ferromagnetic object can be a steel sheet. Alternatively, the ferromagnetic object can be a coil. A force is only generated between the first magnet assembly and the ferromagnetic object when the first mounting body needs to return to its initial mounting position. This embodiment of the application utilizes the first magnet assembly in the first driving component, requiring only the installation of the ferromagnetic object on the base to provide an auxiliary positioning force for the first mounting body to remain in its initial position. The first mounting body can maintain a stable state, occupying little space and being easy to install.

[0018] In one example, a flexible circuit board assembly is also included. This assembly comprises a flexible circuit board and a support plate. At least a portion of the flexible circuit board and a first electromagnetic coil are connected to a base via the support plate. The first electromagnetic coil is electrically connected to the flexible circuit board. A ferromagnetic material is mounted on the support plate, providing high installation flexibility. Alternatively, the ferromagnetic material can be directly mounted on the base.

[0019] In one example, at least one ball bearing is disposed between the connecting wall and the base. The ball bearing is located in the second recess and circumferentially on the second protrusion. The cavity wall of the second recess can rotate relative to the base via the ball bearing. The ball bearing moves flexibly, and its position between the circumferential wall of the second recess and the circumferential wall of the second protrusion minimizes the height occupied by the ball bearing in the second direction, which is beneficial for the miniaturization design of the camera assembly.

[0020] In one example, both the connecting wall and the base are made of plastic, and a metal body is fixed to each plastic body. A ball bearing is located between the metal body of the connecting wall and the metal body of the base. In this embodiment, the metal body is in contact with the ball bearing, resulting in relatively high support strength.

[0021] In one example, a first spring is included, which connects a first mounting body and a second mounting body. The first spring is used to provide the shape of the restoring force for the first mounting body to return to its initial mounting position. The first spring can rotate with the first mounting body. When the first electromagnetic coil is de-energized, the first mounting body can quickly return to its initial mounting position under the restoring force of the first spring.

[0022] Alternatively, / and, a first elastic body is installed in the gap region between the first mounting body and the second mounting body. On the one hand, the first elastic body can maintain the stability of the first mounting body in its initial mounting position; on the other hand, when the first mounting body is driven to rotate, the first elastic body will also be compressed or stretched. When the first electromagnetic coil is de-energized, the first mounting body can quickly return to its initial mounting position under the restoring force of the first elastic body.

[0023] In one example, a retaining mechanism is also included, partially connected to the second mount and partially connected to the base, for providing a restoring force for the second mount to return to its initial position.

[0024] In one example, the retaining mechanism includes a second spring that connects both the second mount and the base. The second spring is configured to provide a restoring force for the second mount to return to its initial position and / or provide a bearing force for the second mount against the base in a second direction. Alternatively and / or, the retaining mechanism includes at least one magnetic reset unit, which includes a first element and a second element. The first element is disposed on the second mounting body, and the second element is disposed on the base. The first element and the second element attract each other to hold the first mounting body in or / and return it to its initial position. The first element and the second element may both be ferromagnetic, and the second mounting body is held in or returned to its initial position by the force of attraction between them.

[0025] Alternatively / and, a portion of the gap between the second mounting body and the base is fitted with a first elastic body.

[0026] In one example, the second driving component includes a second magnet assembly and a second electromagnetic coil, the second magnet assembly being disposed on the first sidewall and / or the second sidewall of the second mounting body, and the second electromagnetic coil being disposed on the base; Alternatively, a second electromagnetic coil may be disposed on the first sidewall and / or the second sidewall of the second mounting body, and a second magnet assembly may be disposed on the base. The magnet-coil structure is simple and occupies little space.

[0027] In one example, a flexible circuit board assembly is also included. The flexible circuit board assembly includes a flexible circuit board and a support plate. At least a portion of the flexible circuit board is positioned on the outer wall side of the base away from the second mounting body via the support plate. The first driving component and the second driving component are electrically connected to an external circuit via the flexible circuit board. The flexible circuit board is arranged along the outer wall side of the base, occupying little space, and the support plate protects the flexible circuit board.

[0028] In one example, the device also includes a housing with an inner cavity. The base, the first mounting body, and the second mounting body are all located within the inner cavity. A second elastic body is also installed at the corner of the second mounting body to elastically abut against the inner wall of the housing. When the electronic device or camera assembly is accidentally dropped, the second mounting body, through the second elastic body, elastically contacts the housing, protecting components such as prisms.

[0029] In one example, the prism is a triangular prism, which also includes a refractive surface. The light-inlet surface and the light-outlet surface are adjacent, and the refractive surface connects the light-inlet surface and the light-outlet surface. Under the premise of meeting the requirements of light path transformation, the triangular prism has a simple structure, occupies little space, and is lightweight.

[0030] This application embodiment also provides a camera module, characterized in that it includes a lens assembly and a camera assembly as described above, wherein the light-emitting surface of the camera assembly faces the light-inlet aperture of the lens assembly.

[0031] This application also provides an electronic device having the above-described camera module.

[0032] The camera module and electronic device provided in this application include a camera assembly, so the periscope camera module and electronic device also have the above-mentioned technical effects of the camera assembly. Attached Figure Description

[0035] Current camera components include a prism, a prism support, and a base. The prism is fixed to the prism support, and the prism support and base are in contact via a spherical mating surface. The prism support rotates in different directions around the mating spherical surface to achieve prism rotation around the z-axis or y-axis. The z-axis and y-axis are parallel to the light-incoming and light-outcoming surfaces of the prism, respectively. Since the current prism support (i.e., the device used to support and adjust the prism) rotates around the same spherical surface, this rotation can be either along the z-axis or y-axis. When the prism support rotates in one direction (e.g., the z-axis), it may cause unexpected deflection in another direction (e.g., the y-axis). This phenomenon is called crosstalk, meaning that adjusting the angle in one direction also affects the angle in another direction, resulting in inaccurate directional adjustment. Overcoming these shortcomings is a technical problem that urgently needs to be solved by those skilled in the art.

[0036] This application provides a technical solution that can reduce the probability of crosstalk when the camera component is adjusted in different directions, thereby improving the accuracy of prism position control.

[0037] The embodiments of this application will be further described in detail below with reference to the accompanying drawings and specific examples.

[0038] The camera component in this application embodiment can be applied to various types of electronic devices, including handheld devices, in-vehicle devices, wearable devices, terminal devices, or other processing devices connected to a wireless modem. These devices may also include cellular phones, smartphones, personal digital assistant (PDA) computers, tablets, laptops, camcorders, video recorders, cameras, smartwatches, smart bracelets, augmented reality (AR) devices, virtual reality (VR) devices, in-vehicle computers, and other devices with imaging capabilities. This application embodiment does not impose special limitations on the specific form of the aforementioned electronic devices. For ease of understanding, the following description uses the application of the camera component to a mobile phone as an example. The mobile phone can be a candybar phone or a flip phone.

[0039] Please see Figure 1 , Figure 1 This is a schematic diagram of the structure of an electronic device provided in an embodiment of this application.

[0040] like Figure 1 As shown, taking a mobile phone as an example, the electronic device 1000 may include a mid-frame 100, a back cover 200, a decorative panel 210, and a screen 500 (see [link to documentation]). Figure 2 (Structural understanding is shown in the diagram). The middle frame 100 and the back cover 200 are part of the housing 5 of the electronic device 1000; that is, the housing 5 of the electronic device 1000 may include the middle frame 100 and the back cover 200. The screen 500 and the back cover 200 are located on both sides of the middle frame 100, and the middle frame 100 can support and fix the screen 500 and provide protection. The screen 500 is used to display image information or video. When the electronic device 1000 is in use, the user can view the content displayed on the screen 500 or perform input operations on the electronic device 1000.

[0041] Please refer to Figure 2 , Figure 2 for Figure 1The exploded view of the electronic device shown indicates that screen 500 includes a light-transmitting cover 510 and a display screen 520. The light-transmitting cover 510 and the display screen 520 are stacked and fixedly connected. The light-transmitting cover 510 mainly serves to protect the display screen 520 from dust. The material of the light-transmitting cover 510 includes, but is not limited to, glass and acrylic. The display screen 520 can be a flexible display screen or a rigid display screen.

[0042] The mid-frame 100 may include a mid-plate 110 and a frame portion 120 connected to the periphery of the mid-plate 110. The mid-plate 110 and the frame portion 120 may be integrally formed or connected by welding, bonding, screws, or other methods. The screen 500 and the back cover 200 are located on opposite sides of the mid-plate 110. The material of the back cover 200 includes, but is not limited to, metal, plastic, fiberglass, glass, ceramic, etc. It is understood that in some other embodiments, when the mobile phone is a foldable screen phone, the screen 500 and the back cover may be the first screen and the second screen of the foldable phone, respectively. For example, the screen 500 is the inner screen of the foldable phone, and the back cover 200 is the outer screen of the foldable phone, or the screen 500 is the outer screen of the foldable phone, and the back cover 200 is the inner screen of the foldable phone.

[0043] The rear cover 200 and the middle plate 110 form a mounting cavity, inside which the main circuit board 400, camera module 300, battery, speaker, earpiece, and other electrical components are installed. A sound outlet 101 is provided on the middle frame 100 to facilitate the propagation of sound from the speaker to the outside of the electronic device 1000. For example, an interface 102 can also be provided on the middle frame 100 for electrical connection with external devices via a data cable. The camera module 300 and the main circuit board 400 can be mounted on the middle plate of the middle frame 100 (the position of the middle plate is determined by...). Figure 2 (For illustrative purposes only), the main circuit board 400 can be the core circuit board within the electronic device 1000 (a circuit board integrating major components such as a processor, system chip, and power chip). The camera module 300 can be electrically connected to the main circuit board 400. For example, the camera module 300 can be connected to the main circuit board 400 via a flexible printed circuit (FPC) 340. The main circuit board 400 is equipped with a processor, which controls the camera module 300 to capture images. When the user inputs a shooting command, the processor receives the command and controls the camera module 300 to capture images of the target object according to the command.

[0044] Please refer to Figure 2The camera module 300 can be fixed to the surface of the middle plate 110 facing the rear cover 200, with the light-receiving surface of the camera module 300 facing the rear cover 200. The rear cover 200 is provided with a mounting opening 202, and a decorative panel 210 covers and is fixed to the mounting opening 202, serving to protect the camera module 300. The decorative panel 210 is provided with a light-transmitting hole 201, allowing light from the scene to enter the light-receiving surface of the camera module 300. The camera module 300 converts the collected light signals into electrical signals to achieve its shooting function. Glass or highly transparent plastic can also be installed at the light-transmitting hole 201 as a decorative element, which also protects the camera module 300. Figure 2 The image shows an example of an electronic device 1000 with a camera module 300 mounted on its rear side; this camera module 300 is also referred to as a rear-facing camera module. In practical applications, the number of camera modules 300 in the electronic device 1000 is not limited to one; there can be more than one, such as one, two, three, or four. Figure 2 This example illustrates a rear-facing camera module comprising three camera modules. Each camera module 300 is positioned appropriately based on the specific structure of the electronic device 1000.

[0045] When the camera module 300 is used as a front-facing camera, a light-transmitting area can be set on the screen 500. Of course, depending on the location of the camera module 300, a light-transmitting area can also be set in other locations on the mid-frame 100.

[0046] The camera module 300 can be one or more of a standard camera module, a telephoto camera module, a wide-angle camera module, an ultra-telephoto camera module, and an ultra-wide-angle camera module. For example, in one embodiment, the electronic device 1000 also has a front-facing camera module.

[0047] Please refer to Figure 3 and Figure 4 , Figure 3 This is a perspective view of the camera module provided in an embodiment of this application, showing only a portion of the structure of the protective shell 30A. Figure 3 The image only schematically illustrates some of the components included in the camera module 300; the actual shape, size, location, and construction of these components are not subject to change. Figure 3 and Figure 4 As well as the limitations of the accompanying figures below.

[0048] For ease of description in the following embodiments, an XYZ coordinate system is established for the camera module 300. Please refer to... Figure 1 and Figure 3 , Figure 4Understand that the light-receiving axis S of the camera module 300 is the Z-axis direction. The XY plane formed by the X-axis and Y-axis directions is perpendicular to the light-receiving axis S. In some embodiments, after the camera module 300 is assembled into the electronic device 1000, the light-receiving axis S of the camera module 300 can be parallel to the thickness direction of the electronic device 1000 (in conjunction with...). Figure 1 and Figure 4 (Understanding). The plane formed by the width and length directions of electronic device 1000 is parallel to the XY plane.

[0049] Please combine Figure 3 and Figure 4 understand, Figure 4 Examples of embodiments in this application Figure 1 The diagram shows an end view of point M in the electronic device. The camera module 300 in this embodiment is a periscope camera module. A periscope camera module is one that uses a refracting prism to change the direction of the light path, such as refracting light rays along the thickness direction (Z-axis) of the electronic device 1000 into light rays perpendicular to the thickness direction (z-axis) of the electronic device 1000. This allows the lenses 3201 of the lens assembly 320 in the camera module 300 and the imaging device to be arranged inside the electronic device 1000 along a direction perpendicular to the thickness direction. This not only enables telephoto shooting but also reduces the size of the electronic device 1000 in the thickness direction.

[0050] Please refer to Figure 3 As shown, the camera module 300 may include a camera assembly 310, a lens assembly 320, and an image sensor assembly 330, all of which can be integrated inside the same protective housing 30A. Alternatively, the camera assembly 310, lens assembly 320, and image sensor assembly 330 can be separately installed in the electronic device 1000. The camera assembly 310, lens assembly 320, and image sensor assembly 330 can be arranged sequentially along the light path of the camera module; that is, the camera assembly 310 can be located on the light-inlet side of the lens assembly 320, and the image sensor assembly 330 can be located on the light-outlet side of the lens assembly 320. Taking the camera module 300 as a rear camera as an example, the camera assembly 310 can be set to correspond to the light-transmitting hole 201 on the back cover 200. Ambient light enters the camera assembly 310 through the light-transmitting hole 201, and the camera assembly 310 reflects the light to the lens assembly 320. After the light is emitted from the lens assembly 320, it enters the image sensor assembly 330. The image sensor assembly 330 converts the light signal into an electrical signal to realize the imaging function of the camera module 300.

[0051] The direction of the light path from the ambient light entering the camera component 310 is S, and the direction of the light path S is usually the thickness direction of the electronic device. Figure 1 , Figure 3 and Figure 4 (As shown in the Z direction), light is reflected within the camera assembly 310 and enters the lens assembly 320 in the outgoing light path direction S1. The outgoing light path direction S1 is typically the planar direction of the electronic device 1000. Therefore, the optical axis direction of the lens assembly 320 can be set along the planar direction of the electronic device 1000. In other words, the length direction of the lens assembly 320 can be set along the planar direction of the electronic device 1000. For example, the length direction of the lens assembly 320 can be the width direction of the electronic device 1000 (see reference). Figure 1 (x-direction) or length direction (refer to) Figure 1 (in the y direction). The camera module 300 bends the light path through the camera assembly 310, and the lens assembly 320 can be arranged along the plane direction where the electronic device 1000 is located. In this way, while ensuring the optical path length of the camera module 300, the size of the camera module 300 in the thickness direction of the electronic device 1000 can be reduced, which is beneficial to the ultra-thin design of the electronic device 1000.

[0052] Please continue to refer to Figure 4 As shown, the lens assembly 320 may include a lens barrel ( Figure 4 (Not shown in the image) and multiple lenses 3201, the lens barrel serving as the basic support structure of the lens assembly 320, the lenses 3201 being disposed inside the lens barrel, and the lenses 3201 being spaced apart along the axial direction of the lens barrel. Each lens 3201 may include a convex lens and a concave lens. Figure 4 Although the shapes of each lens 3201 are not illustrated, this does not impede the understanding of those skilled in the art regarding the lens assembly 320 described in this application. Each lens 3201 is used to focus and correct the light incident on the lens assembly 320 to achieve the imaging function of the lens assembly 320. In addition, some of the multiple lenses 3201 can move along the optical axis of the lens assembly 320 to magnify and reduce the target being photographed, thereby achieving the optical zoom function of the camera module 300.

[0053] Of course, please refer to Figure 5 In another embodiment, a front-end lens assembly 350 may also be provided on the light-receiving side of the camera assembly 310, and the front-end lens assembly 350 may also include a lens barrel. Figure 5 (Not shown in the image) and multiple lenses 3201, the lenses 3201 may include convex lenses and concave lenses, Figure 5 The shapes of each lens 3201 are not shown, but this does not impede the understanding of those skilled in the art regarding the front lens assembly 350 of this application. The front lens assembly 350 can also be an optical zoom lens, or of course, a lens with a fixed focal length.

[0054] Please refer to Figure 4 and Figure 5In this embodiment, the image sensor assembly 330 may include an image sensor 331 and an image processing chip 332. The image sensor 331 may include a charge-coupled device (CCD) or a complementary metal-oxide-semiconductor (CMOS) phototransistor. The image sensor 331 converts light signals into electrical signals, and then transmits the electrical signals to the image processing chip 332 to obtain an image signal. Light entering the lens assembly 320 passes through each lens 3201 and illuminates the photosensitive surface of the image sensor 331. The image sensor 331 converts the light image received on its photosensitive surface into an electrical signal proportional to the light image. This electrical signal is transmitted to the main circuit board 400 via the image processing chip 332 through the FPC.

[0055] In some embodiments, the lens assembly 320 or the image sensor assembly 330 may also be equipped with a driving device (not shown in the figure). The driving device is used to drive the lens assembly 320 or the image sensor assembly 330 to move. For example, the driving device drives the lens assembly 320 or the image sensor 331 to translate along its own plane or rotate around the optical axis of the lens assembly 320 to compensate for the displacement caused by the user's hand tremor, prevent the captured image from being blurry, improve the image clarity, and realize the optical image stabilization function of the camera module 300.

[0056] Please see Figure 6 and Figure 7 In this embodiment of the application, the camera assembly 310 includes a housing 5, a prism 1, a first mounting body 2, a second mounting body 3, and a base 4. Figure 7 (As shown in the diagram). The prism 1, first mounting body 2, second mounting body 3, and base 4 are installed within the inner cavity 53 of the housing 5, which protects the components installed inside. To allow light to reach the prism 1, the housing 5 has clearance openings corresponding to the light-inlet surface 11 and light-outlet surface 12 of the prism 1. For example, the housing 5 has a light-inlet 51 and a light-outlet 52, respectively opposite to the light-inlet surface 11 and light-outlet surface 12 of the prism. The light-inlet 51 and light-outlet 52 can be respectively located on adjacent sidewalls of the housing 5, and can be connected or disconnected. To improve the installation efficiency of the housing 5 with other components, a positioning post 46 can also be provided on the base 4. The specific structure of the housing 5 is not described in detail here.

[0057] Please see Figure 7 , Figure 7 for Figure 6In the cross-sectional view (AA), in this embodiment, prism 1 is an optical element, having at least a light-inlet surface 11, a light-outlet surface 12, and a refractive surface 13, capable of reversing the light path. Prism 1 can be one, or two or more. The prism can be a triangular prism, with a right-angled triangle cross-section. Other structural forms are also possible, as long as they meet the light path propagation requirements. Triangular prisms are simple in structure, lightweight, and occupy little space, which is beneficial for meeting the miniaturization design requirements of the 300-cell camera module. This application continues to describe the technical solution using a triangular prism as an example. The light-inlet surface 11, light-outlet surface 12, and refractive surface 13 of the triangular prism are connected end-to-end. It can be considered that the light-inlet surface 11 and the light-outlet surface 12 are adjacent, and the refractive surface 13 is connected to the light-inlet surface 11 and the light-outlet surface 12. The first mounting body 2 has a support surface 24 for fixing the prism. The refractive surface 13 of prism 1 can be supported on the support surface 24, and the two can be in close contact. Please refer to... Figure 8 It is understood that both end faces 14 of the prism 1 can be bonded and fixed to the first mounting body 2 to improve the reliability of the prism's fixation. For example, adhesive grooves 3C can also be provided on the two side faces 25 of the first mounting body 2, through which liquid adhesive can be injected between the side faces 25 of the first mounting body 2 and the prism 1. The adhesive can be a liquid adhesive or a structural adhesive.

[0058] Combination Figure 4 Understand that the light-inlet surface 11 of prism 1 corresponds to the light-transmitting area of ​​electronic device 1000, for example, the light-inlet surface 11 of prism 1 corresponds to the light-transmitting hole 201 of the rear cover 200 of electronic device 1000. The light-exit surface 12 of prism 1 corresponds to the light-inlet side of lens assembly 320. In this way, light from outside electronic device 1000 shines on the light-inlet surface 11 of prism along the S direction, and after reflection inside prism 1, it exits from the light-exit surface 12 of prism 1 along the S1 direction to enter the light-inlet hole of lens assembly 320. Taking prism 1 as a right-angled triangular prism as an example, the S1 direction and the S direction are perpendicular to each other.

[0059] Please refer to Figure 7 and Figure 8 In this embodiment, the first mounting body 2 is rotatably mounted to the second mounting body 3 via a first rotating shaft 9. That is, the first mounting body 2 can rotate relative to the second mounting body 3 around the first rotating shaft 9. The axial direction of the first rotating shaft 9 is along the y-direction. For the sake of brevity in describing the technical solution, this embodiment defines the axial direction of the first rotating shaft 9 as the first direction. Figure 8 The y-direction is indicated in the text. Combined with... Figure 9 Understood, the second mounting element 3 can be roughly a frame structure. Please refer to... Figure 9 and Figure 10 The second mounting body 3 is disposed on the outer periphery of the first mounting body 2, and the first mounting body 2 is located inside the frame of the second mounting body 3.

[0060] In this embodiment, the first rotating shaft 9 can be fixedly connected to the first mounting body 2, and the first rotating shaft 9 can be fixedly connected to the second mounting body 3 by injection molding or interference fit. The first rotating shaft 9 and the second mounting body 3 rotatably support the position of the first mounting body 2 in the initial assembly state of the camera assembly 310, or the position of the first mounting body 2 in the standard state of the camera assembly 310, or the position of the first mounting body 2 when the first electromagnetic coil 71 in the camera assembly 310 is in a de-energized state. For example, the second mounting body 3 can be provided with mounting holes, and the first rotating shaft 9 is rotatably mounted in the mounting holes.

[0061] Please combine Figure 7 , Figure 8 and Figure 9 Understood, in this embodiment, the camera assembly 310 further includes a first driving component 7, which can drive the first mounting body 2 to rotate relative to the second mounting body 3 around a first direction (y-axis), while the prism 1 rotates with the first mounting body 2 around the first direction. Figure 10 The double-headed dashed arrow in the middle indicates the direction of rotation around the y-axis. That is, the first driving component 7 can drive the first mounting body 2 to rotate in the first plane, which is a plane perpendicular to the first direction (y-axis). In this way, the light-incoming surface 11 and the light-outgoing surface 12 of the prism are deflected around the y-axis, and the position and angle of the light-incoming surface 11 and the light-outgoing surface 12 of the prism are adjusted along the deflection direction.

[0062] Please see Figure 10 In this embodiment, the first driving component 7 can be a coil-magnet assembly. The first driving component 7 includes a first electromagnetic coil 71, a first magnet assembly 72, and a first chip 73. The first mounting body 2 allows the rotating rod in the first direction to achieve closed-loop control via the first chip 73. The first magnet assembly 72 can contain one or more magnets. Figure 8 The diagram shows a first magnet assembly 72 comprising two magnets, namely a first magnet 721 and a second magnet 722. The first magnet 721 and the second magnet 722 have opposite magnetic poles on the side facing the first electromagnetic coil 71, that is, one is the N pole and the other is the S pole.

[0063] Please see Figure 7 , Figure 10 and Figure 11 The first magnet assembly 72 is fixed to the side wall of the first mounting body 2 away from the light-emitting surface 12. In one example, each magnet in the first magnet assembly 72 can be fixed to the first mounting body 2 by adhesive bonding. During installation, the surface of the first magnet assembly 72 and the groove wall of the mounting groove of the first mounting body 2 can be coated with adhesive. In order to improve the fixing reliability of the first magnet assembly, an adhesive groove 3C can also be provided on the first mounting body 2. Liquid adhesive is further filled between the first magnet assembly 72 and the second mounting body 2 through the adhesive groove 3C.

[0064] Please combine Figure 12 It is understood that the first electromagnetic coil 71 can be fixed on the base 4 and positioned opposite the first magnet assembly 72. The electrical connection wire of the first electromagnetic coil 71 is connected to the external circuit board of the camera assembly 310 via the flexible circuit board assembly 6. When the first electromagnetic coil 71 is energized, a magnetic force is generated between the first magnet assembly 72 and the first electromagnetic coil 71, which attracts or repels each other, thereby driving the first mounting body 2 to rotate relative to the second mounting body 3 around a first direction.

[0065] In this embodiment, the force driving the first mounting body 2 to rotate is provided by the cooperation of the coil and the magnet. The structure is relatively simple, and the current flowing through the coil is controllable, with high adjustment flexibility and high adjustment accuracy.

[0066] To minimize the thickness of the camera assembly 310, the first magnet assembly 72 and the first electromagnetic coil 71 are aligned along a third direction ( Figure 10 and Figure 12 Arranged along the x-axis. Please refer to [link / reference]. Figure 13 Along a third direction, a first opening is provided between the first sidewall 3-1 and the second sidewall 3-2 of the second mounting body 3 (see [link]). Figure 13 (Understanding) The first magnet assembly 72 and the first electromagnetic coil 71 are located between the first sidewall 3-1 and the second sidewall 3-2. This close proximity between the first magnet assembly 72 and the first electromagnetic coil 71 helps reduce the size of the camera assembly 310 along a third direction. Furthermore, the absence of any intermediate obstacles between the first electromagnetic coil 71 and the first magnet assembly 72 ensures that the magnetic field strength generated by the first electromagnetic coil 71 is not weakened, allowing for a larger driving force with a smaller coil volume, which is beneficial for the miniaturization design of the camera assembly 310.

[0067] In this embodiment, the first magnet component 72 and the first electromagnetic coil 71 are respectively mounted on the opposing surfaces of the first mounting body 2 and the base 4, so as to minimize the distance between them.

[0068] In this embodiment, the first mounting body 2 mainly serves to support the prism 1. While satisfying the support function, the weight of the first mounting body 2 can be reduced as much as possible, or the structure of the first mounting body 2 can be simplified to facilitate the installation of other components.

[0069] Please combine Figure 14 and Figure 15In this embodiment, the first mounting body 2 has a first recess 211 on its first surface 21 facing away from the light-receiving surface 11, and the connecting wall 3-3 has a first protrusion 3-32. The first protrusion 3-32 is at least partially located inside the first recess 211, and may be completely or partially located inside the first recess 211. The side of the first protrusion 3-32 facing the first mounting body 2 can be flat, simplifying the manufacturing process. The second rotating shaft 41 is at least partially disposed on the first protrusion 3-32. In this embodiment, the first recess 211 can provide clearance space for the installation of the first protrusion 3-32, which is beneficial for reducing the size of the camera assembly 310 along the first direction. Furthermore, the second rotating shaft 41 being disposed on the first protrusion 3-32 can improve the strength of the connection between the second mounting body 3 and the second rotating shaft 41.

[0070] Please combine Figure 7 , Figure 15 , Figure 16 , Figure 17 , Figure 18 and Figure 19 In this embodiment of the application, the second mounting body 3 is supported on the base 4 and is connected to the second rotating shaft 41 ( Figure 15 and Figure 16 (Not shown in the image) is rotatably mounted on the base 4, and the axial direction of the second rotating shaft 41 is parallel to the light-emitting surface 12. Figure 15 The z-direction shown is the axial direction of the second rotating shaft 41. In this application, the axial direction of the second rotating shaft 41 is defined as the second direction. Figure 15 (in the z-direction). The base 4 is located on the side of the second mounting body 3 opposite to the first mounting body 2. The first mounting body 2 is located inside the frame of the second mounting body 3, and the base 4 is located outside the second mounting body 3. The base 4 is also roughly a frame structure. The base 4 is located on the outer periphery of the second mounting body 3. The second rotating shaft 41 can be fixedly installed with either the second mounting body 3 or the base 4, and rotatably installed with the other. To minimize wear and improve the service life of the camera assembly 310, bushings can be provided at both ends of the second rotating shaft 41. The bushings are fixed in the second mounting body 3 or the base 4, and the second rotating shaft 41 is installed in conjunction with the bushings. The first rotating shaft 9 and the bushing 32 can be metal parts.

[0071] Please refer to Figure 19 In this embodiment, the camera assembly 310 further includes a second driving component 8. The second driving component 8 can drive the second mounting body 3 to rotate around a second direction (z-axis). That is, the second driving component 8 can drive the entire assembly formed by the second mounting body 3 and the first mounting body 2 to rotate within a second plane, which is a plane perpendicular to the z-axis (second direction). In this way, the light-incoming surface 11 and the light-outgoing surface 12 of the prism can be deflected around the second direction (z-axis), and the position and angle of the light-incoming surface 11 and the light-outgoing surface 12 of the prism can be adjusted along this deflection direction.

[0072] Figure 19 The image shows that the camera assembly 310 is equipped with two second drive components 8 to maximize the driving force. Specifically, the two second drive components 8 are located on opposite sides of the second mounting body 3 along the first direction. Specifically, the two second drive components 8 are located on opposite sides of the first rotating shaft 9, and they can be installed symmetrically. The second drive components 8 can also be coil-magnet assemblies, combined with... Figure 20 Understanding that a second driving component 8 may include a second electromagnetic coil 81, a second magnet assembly 82, and a second chip 83, the rotation of the second mounting body 3 around a second direction can be achieved through closed-loop control by the second chip 83. The second magnet assembly 82 may contain one or more magnets, combined with... Figure 13 Understanding, in one example, the second magnet assembly 82 includes two third magnets 822 and one fourth magnet 821, where the length of the fourth magnet 821 along the Z-direction is equal to the sum of the lengths of the two third magnets 822 along the Z-direction. The magnetic poles of the third magnets 822 and the fourth magnet 821 on the same side are opposite, for example, from... Figure 13 As can be seen, the magnetic pole of the third magnet 822 facing away from the first sidewall 3-1 is the S pole, and the magnetic pole of the fourth magnet 821 facing away from the first sidewall 3-1 is the N pole. Thus, when the second electromagnetic coil 81 is energized, a significant driving force can be generated between the second electromagnetic coil 81 and the second magnet assembly 82. Of course, the number of magnets in the second magnet assembly 82 is not limited to those described in this paper.

[0073] Combination Figure 13 and Figure 19 Understandably, in one example, the second mounting body 3 includes a first sidewall 3-1 and a second sidewall 3-2 arranged at intervals along a first direction, and two second driving components 8 are respectively disposed at the positions of the first sidewall 3-1 and the second sidewall 3-2. For example... Figure 15 , Figure 16 , Figure 17 and Figure 19 As shown, the base 4 includes a first frame sidewall 4-1 and a second frame sidewall 4-2. The first frame sidewall 4-1 is disposed opposite to the first sidewall 3-1 of the second mounting body 3, and the second frame sidewall 4-2 is disposed opposite to the second sidewall 3-2 of the second mounting body 3. A second electromagnetic coil 81 is provided on both the first frame sidewall 4-1 and the second frame sidewall 4-2. The structures for installing the second electromagnetic coil 81 on the two frame sidewalls can be the same or different. Please refer to... Figure 21 and Figure 22Understandably, this application provides examples of different mounting structures for the first frame sidewall 4-1 and the second frame sidewall 4-2. The first frame sidewall 4-1 has a mounting groove 4-11 for mounting one second electromagnetic coil 81, and the second frame sidewall 4-2 has a third mounting hole 4-22 for mounting another second electromagnetic coil 81. Both the first sidewall 3-1 and the second sidewall 3-2 have second magnet assemblies 82. In this embodiment, the second electromagnetic coil 81 is mounted on the base 4, facilitating connection to the flexible circuit board.

[0074] Of course, in this embodiment, the second electromagnetic coil 81 and the second magnet component 82 can also be disposed on the opposing surfaces of the second mounting body 3 and the base 4, with no other structural obstruction between the second electromagnetic coil 81 and the second magnet component 82, thus avoiding weakening the interaction force between them.

[0075] As described above, in this embodiment, the first rotating shaft 9 is connected between the first mounting body 2 and the second mounting body 3. The first driving component 7 drives the first mounting body 2 to rotate around the first rotating shaft 9, thereby rotating the prism 1 around a first direction. The second rotating shaft 41 is connected between the second mounting body 3 and the base 4. The second driving component 8 drives the second mounting body 3 to rotate around the second rotating shaft 41, thereby rotating the prism 1 around a second direction. This allows the first mounting body 2 to rotate around the first rotating shaft, or / and the second mounting body 3 to rotate around the second rotating shaft 41, based on the vibration direction and angle of the electronic device 1000, to compensate for the vibration of the electronic device 1000. Because the first rotating shaft 9 and the second rotating shaft 41 are separately configured, the rotation adjustment of the prism 1 around the first and second directions does not interfere with each other, improving the adjustment accuracy of the camera assembly 310 and simplifying control.

[0076] Figures 13 to 17 As shown in this embodiment, the second mounting body 3 may further include a connecting wall 3-3, which is connected between the first side wall 3-1 and the second side wall 3-2, and is located on the side of the first side wall 3-1 and the second side wall 3-2 that faces away from the light-incoming surface 11 of the prism. The second mounting body 3 is generally U-shaped. The connecting wall 3-3 is connected to the base 4 via a second pivot 41, and the connecting wall 3-3 is movably supported on the base 4. In this embodiment, the structure of the second mounting body 3 is relatively simple, which is beneficial to the lightweight design requirements of the camera assembly 310.

[0077] Please combine Figure 18 and Figure 19Understood, in this embodiment, the connecting wall 3-3 has a second cavity 3-31 on its second surface 3-33 away from the first mounting body 2, and the base 4 has a second protrusion 45. The second protrusion 45 is at least partially located in the second cavity 3-31, and the other end of the second rotating shaft 41 is connected to the second protrusion 45. In this embodiment, the second protrusion 45 is provided at the position where the second rotating shaft 41 is located on the base 4. The second protrusion 45 has a relatively large thickness, which can improve the strength of the position where the second rotating shaft 41 is located. Furthermore, the second cavity 3-31 is provided on the surface of the second mounting body 3 opposite to the second protrusion 45. The second cavity 3-31 can provide installation space for the second protrusion 45, taking into account both the strength and reliability of use and the small size.

[0078] The shapes of the first protrusion 3-32, the second protrusion 45, the first cavity 211, and the second cavity 3-31 can be reasonably set according to the specific structure, as long as they can meet the above-mentioned functions.

[0079] Similarly, to improve the wear resistance of the second shaft 41, in this embodiment, the second shaft 41 can be fitted with a second bushing 3B, which has good wear resistance. Both the second bushing 3B and the second shaft 41 can be made of metallic materials, such as copper. Please refer again... Figure 18 In one example, the first protrusion 3-32 and the second protrusion 45 are provided with coaxial through holes, and a second bushing 3B is fixed inside each through hole. The two ends of the second rotating shaft are respectively mounted on the two second bushings 3B. The fixing method between the second bushing 3B and the second mounting body 3, and between the second bushing 3B and the base 4, can be the same as the fixing method between the first bushing 32 and the second mounting body 3 described above. The second bushing 3B can be fixed to the first protrusion 3-32 or the second protrusion 45 by adhesive bonding or / and welding.

[0080] Please refer to this again. Figure 18In one specific example, metal bodies are fixed to both the first protrusion 3-32 and the second protrusion 45. These metal bodies can be fixed to the first protrusion 3-32 and the second protrusion 45 via injection molding. In this embodiment, the metal body fixed to the first protrusion 3-32 is defined as the first metal body 33, and the metal body fixed to the second protrusion 45 is defined as the second metal body 43. The second bushing 3B on the first protrusion 3-32 is welded to the first metal body 33, and the second bushing 3B on the second protrusion 45 is welded to the second metal body 43. The first metal body 33 is partially exposed outside the first protrusion 3-32 and has a welding through hole 3E for welding to the second bushing 3B in the first protrusion 3-32. Similarly, the second metal body 43 can be partially exposed outside the second protrusion 45 and has a welding through hole 3E for welding to the second bushing 3B in the second protrusion 45. In this configuration, the end of the second bushing 3B in the first protrusion 3-32 that is away from the second protrusion 45 is welded to the first metal body 33. The end of the second bushing 3B in the second protrusion 45 that is away from the first protrusion 3-32 is welded to the second metal body 43.

[0081] Similarly, welding through holes 3E can be provided on both the first metal body 33 and the second metal body 43 to facilitate welding.

[0082] Please combine Figure 21 and Figure 22 In one example, the base further includes a third frame sidewall 4-3 and a fourth frame sidewall 4-4 connected between the first frame sidewall 4-1 and the second frame sidewall 4-2. The third frame sidewall 4-3 is disposed opposite to the first magnet assembly 72. The first electromagnetic coil 71 is fixed to the third frame sidewall 4-3. A second mounting hole 4-31 may be provided on the third frame sidewall 4-3 to reduce the influence on the electromagnetic field generated by the first electromagnetic coil 71. A second rotating shaft 41 is provided on the fourth frame sidewall 4-4.

[0083] In this embodiment, the first mounting body 2 is rotatably supported by the first rotating shaft 9 and the first side wall 3-1 and the second side wall 3-2 of the second mounting body 3. In order to improve the coaxiality of the first rotating shaft on both sides of the first mounting body 2 with the first side wall 3-1 and the second side wall 3-2, the following structural settings are made to the camera assembly 310.

[0084] Please combine Figure 19 and Figure 23 Understood, in this embodiment of the application, the first rotating shaft 9 penetrates the first mounting body 2, as shown below. Figure 23The first mounting body 2 is provided with a through hole 23. The first rotating shaft includes two end shaft sections 91, which are located outside the through hole 23 and are respectively supported by the first side wall 3-1 and the second side wall 3-2. In this way, the first mounting body 2 is rotatably supported by the two ends of the same first rotating shaft 9 with the first side wall 3-1 and the second side wall 3-2 respectively. As long as the machining accuracy of the first rotating shaft is ensured, the coaxiality of the rotation of the first mounting body 2 and the two side walls of the second mounting body 3 can be achieved, which is beneficial to improving the quality of the camera assembly 310. Typically, the main body 40 of the first mounting body 2, the second mounting body 3, and the base 4 is made of plastic, so the camera assembly 310 is relatively lightweight. In order to improve the wear resistance between the first rotating shaft and the second mounting body 3, the following settings are also made in this application.

[0085] Please see again Figure 24 In this embodiment, the camera assembly 310 further includes two first bushings 32, which are respectively fixed to the first sidewall 3-1 and the second sidewall 3-2. Each first bushing 32 has a first mounting hole 321 on its surface facing the first rotating shaft, and the end shaft segment 91 is rotatably mounted in the first mounting hole 321. In this embodiment, the inner hole of the first bushing 32 rotates in conjunction with the first rotating shaft 9. This reduces the processing difficulty of the first sidewall 3-1 and the second sidewall 3-2, and allows the first bushing 32 to be made of a different material than the second mounting body 3. For example, using a high-strength metal material improves the wear resistance of the first bushing 32 and the first rotating shaft.

[0086] Combination Figure 15 , Figure 20 , Figure 23 and Figure 24 In this embodiment, the first mounting hole 321 on the first bushing 32 is a through hole, and a baffle 34 is fixed to the side wall of each first bushing 32 facing away from the first rotating shaft 9 to block the port of the first mounting hole 321 away from the first rotating shaft 9. The first rotating shaft 9 is located between the two baffles 34. The baffle 34 can restrict the displacement of the first rotating shaft along the first direction to prevent the first rotating shaft 9 from coming out of the first mounting hole 321. In this embodiment, the first mounting hole 321 on the first bushing 32 is a through hole, which is beneficial to improving the concentricity of the first mounting holes 321 on the two first bushings 32 on the first side wall 3-1 and the second side wall 3-2, and the processing technology is relatively simple.

[0087] In this embodiment, the first bushing 32 can be made of a wear-resistant material with relatively low hardness. When the electronic device 1000 is accidentally dropped, the first rotating shaft 9 will impact the baffle 34. The baffle 34 should ideally have high hardness to provide high impact resistance, thereby improving the impact resistance of the camera assembly 310. In this embodiment, the baffle 34 is made of a material with a higher hardness than the first bushing 32. For example, the first bushing 32 can be made of copper, and the baffle 34 can be made of stainless steel. Alternatively, the baffle 34 can be made of other metals with a hardness greater than copper.

[0088] The first bushing 32 may also have a recess 322, and the baffle 34 is installed in the recess 322 to reduce its space occupation. The baffle 34 may also have a welding through hole 3E, and the baffle 34 is welded and fixed to the first bushing 32.

[0089] Please refer to this again. Figure 23 In this embodiment, receiving grooves 36 can be provided on the first sidewall 3-1 and the second sidewall 3-2, and the first bushing 32 is installed inside the receiving groove 36. This can minimize the thickness of the first sidewall 3-1 or the second sidewall 3-2, which is beneficial for reducing the overall size of the camera assembly 310. The first bushing 32 can be fixed to the first sidewall 3-1 or the second sidewall 3-2 by adhesive. Of course, in order to improve the reliability of the fixation between the first bushing 32 and the first sidewall 3-1 or the second sidewall 3-2, the first bushing 32 and the first sidewall 3-1 or the second sidewall 3-2 can be further fixed by welding. For example, a metal body 33 is injection molded inside the first sidewall 3-1 or the second sidewall 3-2, and the first bushing 32 and / or the baffle 34 are welded to the first metal body 33. In order to facilitate welding, a welding through hole 3E is provided on the first metal body 33. Furthermore, the first metal body 33 is located between the first bushing 32 and the second magnet assembly 82, so that the first metal body 33 can effectively isolate the first bushing 32 and the second magnet assembly 82, preventing the first bushing 32 from colliding with the second magnet assembly 82 and damaging the second magnet assembly 82.

[0090] Please combine Figure 4 , Figure 18 , Figure 21 , Figure 22 , Figure 25 and Figure 26To minimize frictional forces between the connecting wall 3-3 and the base 4 during relative movement, in this embodiment, the connecting wall 3-3 and the base 4 can make rolling contact via a ball bearing 44. Specifically, at least one ball bearing 44 is provided between the connecting wall 3-3 and the base 4. The connecting wall 3-3 is supported on the base 4 by the ball bearing 44. The ball bearing 44 can be located inside the second cavity 3-31 and is located circumferentially on the second protrusion 45. The cavity wall of the first cavity 211 is supported on the base 4. The ball bearing 44 is located between the peripheral wall of the second cavity 3-31 and the peripheral wall of the second protrusion 45. This example can minimize the height occupied by the ball bearing 44 in the second direction, which is beneficial for the miniaturization design of the camera assembly 310. In addition, by reasonably setting the shape of the peripheral wall of the first cavity 211 and the peripheral wall of the second protrusion 45 at the installation position of the ball bearing 44, it can be adapted to fit the ball bearing 44. This not only enables the installation and positioning of the ball bearing 44, but also provides high rotational stability for the second mounting body 3. For example, a portion of the peripheral wall of the second protrusion 45 has an arc-shaped surface 451 to mate with the ball 44.

[0091] The number of ball bearings 44 can be one or more. Figure 25 The example shown has three balls 44 arranged in a triangle, which provides relatively high support stability.

[0092] In one specific example, a groove 47 may also be provided on the base 4, and the ball 44 is located inside the groove 47. The groove 47 limits the range of motion of the ball 44 and can further improve the installation stability of the ball 44.

[0093] As described above, a first metal body 33 is fixed inside the connecting wall 3-3, and a second metal body 43 is fixed inside the base 4. To improve the support strength between the connecting wall 3-3 and the ball bearing 44, and between the base 4 and the ball bearing 44, the ball bearing 44 can roll in contact with the first metal body 33 and the second metal body 43, thus combining... Figure 18 Understood. That is to say, the ball bearing 44 is located between the metal body of the connecting wall 3-3 and the metal body of the base 4.

[0094] To improve the installation stability of the second mounting body 3 in its initial installation position and to enable it to quickly return to its initial installation position after the second electromagnetic coil 81 is de-energized, the camera assembly 310 may further include a retaining mechanism, partially connected to the second mounting body 3 and partially connected to the base 4, for providing a restoring force for the second mounting body 3 to return to its initial position. The initial position of the second mounting body 3 refers to its position in the initial assembled state of the camera assembly 310. Several implementations of the retaining mechanism, including a spring, a magnetic reset unit 35, and an elastic body, are given below.

[0095] Please combine Figure 15 , Figure 19 , Figure 25 and Figure 26 It is understood that the retaining mechanism may further include at least one magnetic reset unit 35, which includes a first element 351 and a second element 352. The first element 351 is disposed on the second mounting body 3, and the second element 352 is disposed on the base 4. The first element 351 and the second element 352 are configured to provide a restoring force for the first mounting body 2 to retain and / or return to its initial position. One of the first element 351 and the second element 352 may be a magnet, and the other may be a metal (e.g., iron) that can be attracted by a magnet. Alternatively, both the first element 351 and the second element 352 may be magnets.

[0096] The first element 351 and the second element 352 attract each other, which can improve the installation stability of the second mounting body 3 to a certain extent. When the second electromagnetic coil 81 is energized, the force generated by the second electromagnetic coil 81 and the second magnet assembly 82 can overcome the attraction between the magnetic reset units 35 and drive the second mounting body 3 to rotate relative to the base 4. When the second electromagnetic coil 81 is de-energized, the attraction between the magnetic reset units 35 can provide a restoring force for the second mounting body 3 to return to its initial position to a certain extent.

[0097] Please refer to Figure 19 , Figure 25 and Figure 26 It is understood that in this embodiment, a first elastic body 3D may be installed in a portion of the gap between the second mounting body 3 and the base 4. The first elastic body 3D may be an elastic rubber or a component that is prone to elastic deformation, such as foam. In this way, the first elastic body 3D can improve the installation stability of the second mounting body 3 in the base 4 without affecting the rotation of the second mounting body 3 around the second direction. Similarly, a first elastic body 3D may also be installed in a portion of the gap between the first mounting body 2 and the second mounting body 3.

[0098] Please refer to Figure 27 and Figure 28 In this embodiment, the retaining mechanism may further include a second spring 42, which connects both the second mounting body 3 and the base 4. The second spring 42 is installed in the same way as the first spring 22, and can be fixed by the cooperation of the protrusion 3A and the through hole. The second spring 42 can provide a restoring force for the second mounting body 3 to return to its initial installation position.

[0099] In addition, by reasonably setting the shape of the second spring 42, the second spring 42 can also provide the second mounting body 3 with a resisting force against the base 4 along the second direction, so that the second mounting body 3 can be stably supported on the base 4.

[0100] Please refer to Figure 27 and Figure 30In this embodiment, the camera assembly 310 further includes a first spring 22, which connects the first mounting body 2 and the second mounting body 3. The first spring 22 is configured to provide a restoring force to the first mounting body 2 to return to its initial mounting position. The initial mounting position of the first mounting body 2 refers to its position in the initial assembled state of the camera assembly 310, or its position in the standard state of the camera assembly 310, or its position when the first electromagnetic coil 71 in the camera assembly 310 is de-energized. Similarly, the initial position of the second mounting body 3 in this embodiment also refers to its position in the initial assembled state of the camera assembly 310, or its position in the standard state of the camera assembly 310, or its position when the second electromagnetic coil 81 in the camera assembly 310 is de-energized. The first spring 22 can be a metal sheet with one or more curved structures, which deforms and generates a restoring force under external force. When the first mounting body 2 is in its initial mounting position, the first spring piece 22 can be in its original state, at which time it is not subjected to external force and does not deform. When the first electromagnetic coil 71 is energized, the first mounting body 2 rotates around the first axis, simultaneously causing the first spring piece 22 to move relative to the second mounting body 3, resulting in deformation of the first spring piece 22 and thus generating a restoring force. When the first electromagnetic coil 71 is de-energized, under the restoring force of the first spring piece 22, the first mounting body 2 can quickly return to its initial mounting position. In this embodiment, the spring piece occupies a relatively small space.

[0101] like Figure 27 As shown, on the same side of the first mounting body 2 and the second mounting body 3 ( Figure 27 The diagram shows that both have protruding posts 3A on the side near the light-incoming surface 11 of the prism. The first spring piece 22 has a through hole, which mates with the protruding post 3A to fix the first spring piece 22 to the first mounting body 2, and to the second mounting body 3. This fixing method is relatively simple.

[0102] Please combine Figure 28 It is understood that in this embodiment of the application, the camera assembly 310 may also be provided with at least one ferromagnetic material 10. Figure 28 The image shows a ferromagnetic object 10 mounted on a support plate 62, which is mounted on a base 4. Figure 28 (The base is not shown). The ferromagnetic body 10 and the first electromagnetic coil 71 are located on the same side of the base 4, and there is an attractive force between the first magnet assembly 72 and the ferromagnetic body 10. The ferromagnetic body 10 can be an iron-containing material, such as steel, or it can be a magnet. The ferromagnetic body 10 and the first magnet assembly 72 attract each other, which helps the first mounting body 2 to remain and / or return to its initial mounting position.

[0103] The first magnet component 72 attracts the ferromagnetic body 10, which can improve the installation stability of the first mounting body 2 to a certain extent. When the first electromagnetic coil 71 is energized, the force generated by the first electromagnetic coil 71 and the first magnet component 72 can overcome the attraction between the first magnet component 72 and the ferromagnetic body 10, driving the first mounting body 2 to rotate relative to the second mounting body 3. When the first electromagnetic coil 71 is de-energized, the attraction between the first magnet component 72 and the ferromagnetic body 10 can provide a restoring force for the first mounting body 2 to return to its initial installation position to a certain extent.

[0104] This application embodiment utilizes the first magnet component 72 in the first driving component 7, which only requires the installation of the ferromagnet 10 on the base 4, occupying little space and making installation convenient.

[0105] Please see Figure 29 , Figure 29 The diagram shows the distribution of the main components, including the first driving component 7, the second driving component 8, the first rotating shaft 9, the second rotating shaft 41, the ferromagnetic body 10, and the magnetic reset unit 35.

[0106] When the electronic device 1000 is accidentally dropped, the second mounting body 3 will inevitably rotate relative to the base 4 under the action of vibration. If the rotation angle of the second mounting body 3 is too large, it will collide with the housing 5. In order to reduce the collision damage between the second mounting body 3 and the housing 5, the present application has also made the following settings.

[0107] Please see Figure 16 and Figure 27 In this embodiment, a second elastic body 31 is also installed at the corner of the second mounting body 3 to elastically abut against the inner cavity wall of the housing 5, which greatly reduces the probability of the second mounting body 3 being damaged by direct collision with the housing 5.

[0108] Please refer to Figure 12 , Figure 22 , Figure 28 and Figure 31In this embodiment, the camera assembly 310 further includes a flexible circuit board assembly 6, which comprises a flexible circuit board 61 and a support plate 62. At least a portion of the flexible circuit board 61 is positioned on the outer wall of the base 4 away from the second mounting body 3 via the support plate 62. The first driving component 7 and the second driving component 8 are electrically connected to an external circuit via the flexible circuit board. Taking the first driving component 7 including a first electromagnetic coil 71 and the second driving component 8 including a second electromagnetic coil 81 as an example, the flexible circuit board 61 has a first electrical connection terminal electrically connected to the first electromagnetic coil 71 and a second electrical connection terminal electrically connected to the second electromagnetic coil 81. The number and specific location of the first and second electrical connection terminals depend on the number of corresponding electromagnetic coils and their installation positions. The external connection end 610 of the flexible circuit board 61, which is electrically connected to the external circuit, is located outside the housing 5.

[0109] In this embodiment, the support plate 62 can be a separate unit. For example, support plates 62 can be provided on one or more sides of the base 4 away from the second mounting body 3 to support and position the flexible circuit board. The support plate 62 plays a role in protecting the flexible circuit board to a certain extent. Furthermore, the support plate 62 located on the fourth frame sidewall 4-4 of the base 4 can directly close the opening on that side of the housing 5, thus serving as part of the housing 5 and minimizing the weight of the camera assembly 310.

[0110] Please refer to this again. Figure 22 To protect the flexible circuit board 61 as much as possible, a clearance groove 4-21 can be provided on the outer wall of the base 4. Please refer to... Figure 9 It is understood that the flexible circuit board 61 should not protrude beyond the outer wall of the base 4 as much as possible. Circumvention grooves can also be made on other walls, but these are not shown in detail here.
