Description

Technical Field

[0001] The embodiments of the present application relate to the field of imaging technologies, and in particular, to a camera component, a camera module, and an electronic device. Background Art

[0002] An electronic device usually has a camera module to meet the needs of taking pictures or shooting videos. To balance the requirements of the ultrathin design and long - focal - length shooting of the electronic device, a periscope camera module is widely used in electronic devices. The periscope camera module includes a camera component, and the camera component includes a driving component and a prism. The driving component can drive the prism to rotate around two directions to adjust the optical path, so as to achieve optical image stabilization. However, when the prism adjusts its position, the two directions often interfere with each other, resulting in difficult adjustment and seriously affecting the quality of pictures or video images. Summary of the Invention

[0003] The purpose of the embodiments of the present application is to provide a camera component with relatively high adjustment accuracy. Another purpose of the embodiments of the present application is to provide a camera module and an electronic device including the above - mentioned camera component.

[0004] The embodiments of the present application provide a camera component, including:

[0005] A prism having an incident light surface and an emergent light surface;

[0006] A first mounting body, on which the prism is mounted;

[0007] A second mounting body and a first rotating shaft, and the first mounting body is rotatably supported by the second mounting body through the first rotating shaft;

[0008] A base and a first rolling body, at least a part of the surface of the first rolling body is a first spherical surface, and the second mounting body is rotatably supported by the base through the first spherical surface;

[0009] A first driving component for driving the first mounting body to rotate relative to the second mounting body around the first rotating shaft;

[0010] A second driving component for driving the second mounting body to rotate relative to the base, and under the action of the first spherical surface, the second mounting body can rotate relative to the base around a second direction.

[0011] In the implementation of this application, 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, and a first rolling body is provided between the second mounting body and the base. Under the action of the first rolling body, the second driving component can drive the second mounting body to rotate around a second direction relative to the base, thereby rotating the prism around the second direction. In this way, the first mounting body can be driven to rotate around the first rotating shaft, or / and the second mounting body can be driven to rotate relative to the base according to the shaking direction and shaking angle of the electronic device to compensate for the shaking amount of the electronic device. Because the first rotating shaft and the first rolling body are provided separately, the rotation adjustment of the prism around the first direction and the second direction do not interfere with each other, thereby improving the adjustment accuracy of the camera assembly and making the control relatively simple.

[0012] In one example, the second mounting body includes a first side wall and a second side wall, and the space between the first side wall and the second side wall is used to mount the first mounting body; a first rotating shaft passes through the first mounting body, and the second mounting body also includes a connecting wall, the connecting wall is connected between the first side wall and the second side wall, and is located on the side of the first side wall away from the light-entering surface; the first rotating shaft includes two end shaft segments, and the two end shaft segments are respectively rotatably supported by the first side wall and the second side wall. In this way, the first mounting body is rotatably supported by the first side wall and the second side wall respectively through the two end portions of the same first rotating shaft. It only needs to ensure the processing accuracy of the first rotating shaft to achieve the coaxiality of the rotation of the two side walls of the first mounting body and the second mounting body, which is beneficial to improving the quality of the camera assembly.

[0013] In one example, two first bushings are further included, the two first bushings being fixed to the first side wall and the second side wall, respectively. A first mounting hole is provided on the surface of the first bushing facing the first rotating shaft. The hole wall of the first mounting hole includes two first inclined surface segments arranged at an angle, and the distance between the two first inclined surface segments decreases as the distance from the central axis of the first mounting hole increases. The outer wall of the end shaft segment is partially supported by the two first inclined surface segments. The end shaft segment of the first rotating shaft is supported on the two first inclined surface segments. The two first inclined surface segments can serve to position the first rotating shaft, thereby facilitating improved coaxiality of the first rotating shaft when installed on the two first bushings.

[0014] In one example, the first sleeve includes a bottom surface and two side surfaces, each of which is connected to the bottom surface by a second inclined surface segment. The distance between the two second inclined surface segments decreases as the distance from the central axis of the first mounting hole increases. The first side wall or the second side wall includes a receiving groove, and the receiving groove has an inclined surface that mates with the two second inclined surface segments. The structure supported by the first sleeve and the receiving groove is generally V-shaped, which allows for precise positioning of the first sleeve and further improves the coaxiality of the two first sleeves mounted on the second support body.

[0015] In one example, a third element and a fourth element are further included. The third element is located on the first sidewall or the second sidewall, and the fourth element is located on the first mounting body. The third and fourth elements magnetically attract or repel each other, thereby applying a force parallel to the first direction to the first mounting body. Thus, under the magnetic force of the third and fourth elements, the first mounting body exerts a predetermined force on the second mounting body in the first direction, thereby preventing the first mounting body from moving in the first direction and improving the stability of the camera assembly.

[0016] In one example, the first driving component includes a first magnet assembly and a first electromagnetic coil, wherein the first magnet assembly is located on the first mounting body and the first electromagnetic coil is mounted on the second mounting body, or alternatively, the first magnet assembly is located on the second mounting body and the first electromagnetic coil is mounted on the first mounting body. In the embodiment of the present application, the first electromagnetic coil is mounted on the second mounting body and can rotate relative to the base about the Z direction along with the second mounting body. In this way, the distance between the first electromagnetic coil and the first magnet assembly does not change due to the rotation of the second mounting body about the Z direction, further reducing the effect of the rotation of the second mounting body about the Z direction on the rotation of the first mounting body about the x direction.

[0017] In one example, the first magnet assembly and the first electromagnetic coil are arranged along a third direction, a first opening is defined between the first sidewall and the second sidewall of the second mounting body along the third direction, and the first magnet assembly or the first electromagnetic coil is located at the first opening, wherein the third direction is perpendicular to the light-emitting surface. The first opening provides space for the installation of the first magnet assembly or the first electromagnetic coil, thereby making the camera assembly more compact and miniaturized.

[0018] In one example, the first electromagnetic coil is located in the first opening, and the camera assembly further includes a flexible circuit board assembly, which includes a flexible circuit board and a support plate. The flexible circuit board has a first main body, and the support plate includes a first support portion. The first support portion is located on a side of the first main body facing away from the first electromagnetic coil. The first main body and the first electromagnetic coil are connected to the second mounting body via the first support portion, and the first electromagnetic coil is electrically connected to the first main body. The first support portion can be fixed to the second mounting body by bonding or other means. The first support portion can increase the strength of the flexible circuit board assembly while facilitating the fixing of the electromagnetic coil.

[0019] In one example, the flexible circuit board further includes a second main body portion and a connecting section. The second main body portion is connected to the base, and the first main body portion is connected to the second main body portion via the connecting section. The connecting section can change its posture as the second mounting body rotates. The connecting section is a free section that can adapt to changes in the position of the second mounting body to meet the movement requirements of the second mounting body.

[0020] In one example, the base has a second opening that is opposite the first opening. The projections of the first main body and the first support portion on a plane parallel to the light-emitting surface are located within the projection of the second opening on a plane parallel to the light-emitting surface. The connecting section extends from the second opening to connect to the second main body. This facilitates the installation of components such as the first support portion and the first main body located at the first opening.

[0021] In one example, at least one ferromagnet is further included, which is installed on the first support part. The ferromagnet 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 ferromagnet to generate a force that causes the first installation body to return to the initial installation position. There can always be a force between the first magnet assembly and the ferromagnet, for example, the ferromagnet is a steel sheet. Of course, the ferromagnet can also be a coil, and when the first installation body needs to return to the initial installation position, a force is generated between the first magnet assembly and the ferromagnet. The embodiment of the present application utilizes the first magnet assembly in the first driving component. It only needs to install a ferromagnet on the base to provide an auxiliary positioning force for the first installation body to be in the initial position. The first installation body can maintain a stable state, occupy a small space, and is easy to install.

[0022] In one example, the first rolling element is located between the connecting wall and the base, and the connecting wall is supported on the base through the first spherical portion of the first rolling element. The second mounting body of this structure is simple in structure and relatively light in weight.

[0023] In one example, the first rolling element includes a first ball bearing, a first mounting recess is provided on the connecting wall, and a second mounting recess is provided on the base. The first ball bearing is partially located in the first mounting recess and rotatably engages with the first mounting recess, while the first ball bearing is partially located in the second mounting recess and rotatably supported by the second mounting recess. The ball bearing has a simple structure and high flexibility.

[0024] In one example, the first mounting recess is in line contact with the first spherical portion of the first ball located therein, or / and the second mounting recess is in line contact with the first spherical portion of the first ball located therein. The first mounting recess and the second mounting recess can be arranged in a generally V-shaped configuration. This provides greater mounting stability for the first ball.

[0025] Of course, the cavity wall of the first mounting recess has at least two inclined surfaces, and the third ball abuts against all inclined surface points in the first accommodating cavity; or / and, the cavity wall of the second mounting recess has at least two inclined surfaces, and the third ball abuts against all inclined surface points in the second accommodating cavity; the third ball contacts the cavity wall at two or more points, the contact area is small, the friction resistance of the third ball is small when it rotates, and the tapered V-groove or conical groove formed by the inclined surface in the cavity wall is conducive to the stable installation of the second ball and improves the rotation stability.

[0026] In one example, the first surface of the first mounting body facing away from the light-entering surface has a first cavity, the connecting wall has a first protrusion, the first protrusion is at least partially located inside the first cavity, and the first mounting recess is located on the side of the connecting wall facing away from the first protrusion; the first cavity can provide an avoidance space for the installation of the first protrusion, which is beneficial to reducing the size of the camera assembly along the first direction, and the second rotating shaft is arranged on the first protrusion, which can improve the strength of the second mounting body connecting to the second rotating shaft position.

[0027] Alternatively, or alternatively, a second surface of the connecting wall facing away from the first mounting body may include a second concave cavity, the base may include a second raised portion, the second raised portion being at least partially located in the second concave cavity, and the second mounting recess being located in the second raised portion. In this embodiment, the second raised portion is provided on the base at the location where the second rotating shaft is provided. The second raised portion is relatively thick, thereby enhancing the strength of the location where the second rotating shaft is provided. Furthermore, a second concave cavity may be provided on the surface of the second mounting body opposite the second raised portion. The second concave cavity may provide mounting space for the second raised portion, thereby achieving a balance between strength and reliability in use and a compact size.

[0028] In one example, both the first and second protrusions are provided with coaxial through-holes, each of which is secured with a metal seat, and the first or second mounting recess is disposed within the metal seat. This can improve the wear resistance of the first rolling element and the overall durability of the product.

[0029] In one embodiment, at least two second rolling balls are further included, each of which is located circumferentially of the first rolling ball. The connecting wall is further rotatably supported on the base by the second rolling balls. The second rolling balls are located between the first rolling element and the third frame side wall, providing relatively high support stability and a compact structure.

[0030] In one example, it includes a first spring clip, which connects the first mounting body and the second mounting body, and is used to provide the shape of a restoring force for the first mounting body to return to the initial mounting position; the first spring clip can be deformed as the first mounting body rotates, and when the first electromagnetic coil is powered off, the first mounting body can quickly return to the initial mounting position under the action of the restoring force of the first spring clip.

[0031] Alternatively, or alternatively, a first elastic member is installed in a portion of the gap between the first mounting body and the second mounting body. The first elastic member maintains the stability of the first mounting body in its initial mounting position. Furthermore, when the first mounting body is driven to rotate, the first elastic member is compressed or stretched. When the first electromagnetic coil is de-energized, the first mounting body can quickly return to its initial mounting position due to the restoring force of the first elastic member. The first elastic member can be a specific elastic member such as rubber or silicone.

[0032] In one example, a second elastic piece is included. The second elastic piece is connected to the second mounting body and the base at the same time. The second elastic piece is used to provide a restoring force for the second mounting body to return to the initial position, or / and provide a shape for the second mounting body to abut against the base along the second direction. The second elastic piece can deform as the second mounting body rotates. After the second electromagnetic coil is powered off, under the action of the restoring force of the second elastic piece, the second mounting body can quickly return to the initial mounting position.

[0033] Or / and, at least one magnetic reset unit is included. The magnetic reset unit includes a first element and a second element. The first element is arranged on the second mounting body, and the second element is arranged on the base. The first element and the second element attract each other to keep or / and restore the first mounting body to the initial position. In this way, the reset speed of the second mounting body can be further improved, and the mounting stability of the second mounting body is facilitated.

[0034] Or / and, a first elastic body is installed in some areas of the gap between the second mounting body and the base.

[0035] In one example, the first driving component includes a first magnet assembly, a first electromagnetic coil, and a first chip. The first chip is located outside the first electromagnetic coil. The first electromagnetic coil has a middle through hole, and a second elastic body is arranged at the position of the middle through hole. The second elastic body partially protrudes from the side of the first electromagnetic coil facing the first magnet assembly. In this way, when the first mounting body rotates around the first direction, the distance between the first mounting body and the second mounting body changes. Because the second elastic body protrudes from the first electromagnetic coil, the first magnet assembly first contacts the second elastic body, thus avoiding the collision between the first magnet assembly and the first electromagnetic coil and playing a role in protecting the first electromagnetic coil.

[0036] Or / and, the second driving component includes a second magnet assembly, a second energized coil, and a second chip. The second chip is located outside the second electromagnetic coil. The second electromagnetic coil has a middle through hole, and a second elastic body is arranged at the position of the middle through hole. The second elastic body partially protrudes from the side of the second electromagnetic coil facing the second magnet assembly. The function of the second elastic body in the second electromagnetic coil is to avoid the collision between the second electromagnetic coil and the second magnet assembly and protect the second electromagnetic coil.

[0037] In one example, the second driving component includes a second magnet assembly and a second energized coil. The second magnet assembly is arranged on the first side wall and / or the second side wall of the second mounting body, and the second energized coil is arranged on the base.

[0038] Or, the second magnet assembly is arranged on the first side wall and / or the second side wall of the second mounting body, and the second magnet assembly is arranged on the base.

[0039] In one example, it further includes a housing having an inner cavity, and the prism, the first mounting body, the second mounting body and the base are mounted in the inner cavity of the housing. A first elastic body is provided between the first mounting body and the housing, so as to avoid direct collision between the first mounting body and the housing and prevent abnormal noise from occurring.

[0040] In one example, it further includes a magnetic adsorption assembly. The magnetic adsorption assembly includes a fifth element and a sixth element, which are respectively arranged on the connecting wall and the first mounting body, and the fifth element and the sixth element attract each other in the second direction. This is beneficial to improving the mounting stability of the first mounting body.

[0041] In one example, the prism is a triangular prism. The triangular prism further includes a refracting surface, and the light incident surface and the light exiting surface are adjacent. The refracting surface connects the light incident surface and the light exiting surface. On the premise of meeting the requirements of optical path transformation, the triangular prism has a simple structure, occupies a small space and is light in weight.

[0042] The embodiment of the present application further provides a camera assembly, including:

[0043] A prism, having a light incident surface and a light exiting surface;

[0044] A first mounting body, and the prism is mounted on the first mounting body;

[0045] A second mounting body and a second rolling body, at least part of the surface of the second rolling body is a second spherical surface part, and the first mounting body is rotationally supported on the second mounting body through the second spherical surface part;

[0046] A base and a first rolling body, at least part of the surface of the first rolling body is a first spherical surface part, and the second mounting body is rotationally supported on the base through the first spherical surface part;

[0047] A first driving component, under the action of the second spherical surface, the first driving component drives the first mounting body to rotate relative to the second mounting body around the first direction;

[0048] A second driving component, under the action of the first spherical surface part, the second driving component drives the second mounting body to be able to rotate relative to the base around the second direction.

[0049] In the implementation of this application, under the driving force of the first driving component, the first mounting body can rotate around the second rolling body connected between the first mounting body and the second mounting body, so as to realize the rotation of the prism around the first direction. Under the driving force of the second driving component, the second mounting body can rotate around the first rolling body connected between the second mounting body and the base, so as to realize the rotation of the prism around the second direction. In this way, according to the shaking direction and shaking angle of the electronic device, the first mounting body can be driven to rotate around the first direction, and / or the second mounting body can be driven to rotate relative to the base around the second direction, so as to compensate for the shaking amount of the electronic device. Since the second rolling body and the first rolling body are arranged between different components, that is, they are separately arranged, the rotation adjustment of the prism around the first direction and the second direction does not interfere with each other, which improves the adjustment accuracy of the camera module, and the control is relatively simple. In addition, the two components are connected by rolling of the rolling body, so the movement flexibility is relatively high, the volume occupied by the rolling body is relatively small, and the weight is also relatively light.

[0050] In one example, the first surface of the first mounting body facing away from the light incident surface has a first concave cavity. The first concave cavity has a third opening and a top wall opposite to the third opening. The second mounting body has a support platform, the support platform is located inside the first concave cavity, and the second rolling body is located between the top wall and the support platform. The support platform is partially located inside the first concave cavity, and the structures of the second mounting body and the first mounting body are relatively compact, which is beneficial to the miniaturization of the camera module.

[0051] In one example, two second rolling bodies are arranged between the top wall and the support platform, and the two second rolling bodies are arranged at intervals along the first direction, and the support platform is arranged opposite to the second rolling bodies one by one. The distance between the two second rolling bodies along the first direction can be as large as possible, so that the support stability of the first mounting body is relatively high.

[0052] In one example, the second rolling body is a third ball. The top wall and the support platform both have receiving cavities for rotatably cooperating with one third ball. The third ball is in point contact rotation with the receiving cavity. One receiving cavity and the third ball have at least two contact points. The cavity wall of the receiving cavity and the third ball can have two or more than three contact points. In this way, the third ball can be effectively fixed, and the problem of pits on the third ball can be effectively avoided.

[0053] Alternatively, the third ball rotates in line contact with the receiving cavity. The cavity wall of the receiving cavity has an annular surface for cooperating with the third ball, and the contact position between the annular surface and the third ball is an annular line. In this embodiment, the receiving cavity is easy to process, and the support stability is relatively high and the friction is small.

[0054] In one example, the wall of one of the accommodating cavities has two inclined surfaces, with the plane of symmetry of the two inclined surfaces parallel to the first direction. The walls of the remaining accommodating cavities have at least three inclined surfaces, and the third ball abuts against all inclined surfaces in the accommodating cavity. In this embodiment, a greater number of inclined surfaces results in a more uniform force applied to the third ball.

[0055] In one example, the second mounting body includes a first side wall, a second side wall, and a connecting wall. The connecting wall is connected between the first side wall and the second side wall and is located on the side of the first side wall facing away from the light-entering surface. The space between the first side wall, the second side wall, and the connecting wall is used to mount the first mounting body. Two support platforms are located on the connecting wall, and the first rolling body is located between the connecting wall and the base. In this embodiment, the second rolling body and the first rolling body are located on either side of the connecting wall, fully utilizing the space below the first mounting body. The camera assembly structure is relatively compact, and the thickness of the connecting wall is reasonably set to meet the overall strength requirements of the camera assembly 1.

[0056] The present application also provides a camera module, comprising a lens assembly and any of the above-mentioned camera assemblies, wherein the light-emitting surface of the camera assembly faces the light-inlet hole of the lens assembly.

[0057] The present application also provides an electronic device having the above-mentioned camera module.

[0058] The camera module and electronic device provided in the embodiments of the present application include a camera assembly, so the camera module and electronic device also have the above-mentioned technical effects of the camera assembly. BRIEF DESCRIPTION OF THE DRAWINGS

[0112] The current camera assembly includes a prism, a prism support, and a base. The prism is fixed to the prism support, and the prism support is in spherical mating contact with the base. The prism support rotates around its mating sphere with the base in different directions to achieve the rotation of the prism around the z-axis or the y-axis. The z-axis and the y-axis are two directions parallel to the light incident surface and the light exiting surface of the prism, respectively. Since the current prism supports (i.e., the devices for supporting and adjusting the prism) all rotate around the same sphere, and this rotation can be a rotation around the z-axis or the y-axis. When the prism support rotates in one direction (e.g., the z-axis), it may cause an unexpected deflection in another direction (e.g., the y-axis). This phenomenon is called the crosstalk phenomenon, that is, when adjusting the angle in one direction, the angle in another direction will also be affected, resulting in inaccurate adjustment of the direction. How to at least overcome the above defects is a technical problem that those skilled in the art urgently need to solve.

[0113] This application provides a technical solution that can reduce the probability of crosstalk phenomenon occurring when the camera assembly is adjusted in different directions, thereby improving the accuracy of prism position control.

[0114] The following will further elaborate on the embodiments of this application in conjunction with the accompanying drawings and specific embodiments.

[0115] The camera assembly in the embodiments of this application can be applied to various types of electronic devices. The electronic devices can include handheld devices, vehicle-mounted devices, wearable devices, terminal devices, or other processing devices connected to a wireless modem. They can also include cellular phones, smart phones, personal digital assistants (PDAs), computers, tablet computers, laptops, laptop computers, cameras, video recorders, cameras, smart watches, smart wristbands, augmented reality (AR) devices, virtual reality (VR) devices, vehicle-mounted computers, and other devices with imaging functions. The specific forms of the above electronic devices are not particularly limited in the embodiments of this application. For the convenience of understanding, the following description is based on the example of the camera assembly being applied to a mobile phone. The mobile phone can be a straight-bar mobile phone or a folding mobile phone.

[0116] Please refer to Figure 1 , Figure 1 which is a schematic structural diagram of the electronic device provided by the embodiments of this application.

[0117] As shown in Figure 1As shown, taking the electronic device as a mobile phone as an example, the electronic device 1000 may include a middle frame 100, a rear cover 200, a decorative plate 210, and a screen 500 (please refer to Figure 2 for the structural understanding shown in it). The middle frame 100 and the rear cover 200 are part of the housing 5 of the electronic device 1000. That is to say, the housing 5 of the electronic device 1000 may include the middle frame 100 and the rear cover 200. The screen 500 and the rear cover 200 are respectively located on both sides of the middle frame 100. The middle frame 100 can support and fix the screen 500 and provide protection. The screen 500 is used to display image information or videos. 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.

[0118] Please refer to Figure 2 , Figure 2 is Figure 1 the exploded view of the shown electronic device. The screen 500 includes a light-transmitting cover plate 510 and a display screen 520. The light-transmitting cover plate 510 and the display screen 520 are stacked and fixedly connected. The light-transmitting cover plate 510 is mainly used to protect the display screen 520 and prevent dust. The material of the light-transmitting cover plate 510 includes but is not limited to glass, acrylic, etc. The display screen 520 can be a flexible display screen or a rigid display screen.

[0119] The middle frame 100 may include a middle plate 110 and a frame portion 120 connected to the periphery of the middle plate 110. The middle plate 110 and the frame portion 120 can be integrally formed or connected by welding, bonding, screws, etc. The screen 500 and the rear cover 200 are respectively located on both sides of the middle plate 110. The material of the rear cover 200 includes but is not limited to metal, plastic, fiberglass board, glass, ceramic, etc. It can be understood that in some other embodiments, when the mobile phone is a folding screen mobile phone, the screen 500 and the rear cover 200 can also be the first screen and the second screen of the foldable mobile phone respectively. For example, the screen 500 is the inner screen of the foldable mobile phone, and the rear cover 200 is the outer screen of the foldable mobile phone, or the screen 500 is the outer screen of the foldable mobile phone, and the rear cover 200 is the inner screen of the foldable mobile phone.

[0120] An installation cavity is formed between the rear cover 200 and the middle plate 110. Electrical components such as a main circuit board 400, a camera module 300, a battery, a speaker, and a receiver are installed inside the installation cavity. Sound holes 101 are provided on the middle frame 100 to facilitate the sound of the speaker to spread to the outside of the electronic device 1000. Exemplarily, an interface 102 can also be provided on the middle frame 100 to be electrically connected to an external device through a data cable. Among them, the camera module 300 and the main circuit board 400 can be installed on the middle plate of the middle frame 100 (the position of the middle plate is combined with Figure 2(Understand), the main circuit board 400 can be the core circuit board within the electronic device 1000 (a circuit board integrated with main components such as a processor, system chip, power chip, etc.), and the camera module 300 can be electrically connected to the main circuit board 400. Exemplarily, the camera module 300 can be connected to the main circuit board 400 through a module flexible printed circuit (FPC) 340. A processor is provided on the main circuit board 400, and the camera module 300 is controlled by the processor to capture images. When the user inputs a shooting instruction, the processor receives the shooting instruction and controls the camera module 300 to shoot the object according to the shooting instruction.

[0121] Please refer to Figure 2 , the camera module 300 can be fixed to the surface of the middle plate 110 facing the rear cover 200, and the light incident surface of the camera module 300 faces the rear cover 200. The rear cover 200 is provided with an installation opening 202, and the decorative plate 210 covers and is fixed at the installation opening 202. The decorative plate 210 is used to protect the camera module 300. A light-transmitting hole 201 is provided on the decorative plate 210. The light-transmitting hole 201 allows the scene light to enter the light incident surface of the camera module 300, and the camera module 300 converts the collected optical signal into an electrical signal to realize the shooting function of the camera module 300. A glass or a plastic with high transparency can also be installed at the position of the light-transmitting hole 201 as a decorative part, and at the same time, it can also protect the camera module 300. Figure 2 An example of a camera module 300 provided on the back side of the electronic device 1000 is shown in, and this camera module 300 is also called a rear camera module. In practical applications, the number of camera modules 300 in the electronic device 1000 can be not limited to one, and the number of camera modules 300 can be more than one, such as one, two, three, four, Figure 2 Taking a rear camera module including three camera modules as an example for illustration. Each camera module 300 is set at a suitable position according to the specific structure of the electronic device 1000.

[0122] When the camera module 300 is used as a front camera, a light-transmitting area can be provided on the screen 500. Of course, according to the different positions where the camera module 300 is set, a light-transmitting area can also be provided at other positions of the middle frame 100.

[0123] 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 example, the electronic device 1000 also has a front camera module.

[0124] Implementation 1

[0125] Please refer toFigure 3 and Figure 4 , Figure 3 is a perspective view of the camera module provided by the embodiment of the present application, in which only a partial structure of the protective case 30A is shown. Figure 3 Only some components included in the camera module 300 are schematically shown therein, and the actual shape, actual size, actual position, and actual structure of these components are not limited by Figure 3 and Figure 4 and the following respective drawings.

[0126] For the convenience of describing the following respective embodiments, an XYZ coordinate system is established for the camera module 300. Please refer to Figure 1 and Figure 3 、 Figure 4 Understand that the direction of the light incident axis S of the camera module 300 is the Z-axis direction. The XY plane formed by the X-axis direction and the Y-axis direction is perpendicular to the direction of the light incident axis S. In some embodiments, after the camera module 300 is assembled to the electronic device 1000, the direction of the light incident axis S of the camera module 300 may be parallel to the thickness direction of the electronic device 1000 (please refer to Figure 1 and Figure 4 for understanding). The plane formed by the width direction and the length direction of the electronic device 1000 is parallel to the XY plane.

[0127] Please refer to Figure 3 and Figure 4 for understanding, Figure 4 is a cross-sectional view at M in the Figure 1 shown electronic device in the embodiment of the present application. The camera module 300 in the embodiment of the present application is a periscope camera module. A periscope camera module is a type that changes the light path direction through a refraction prism, such as refracting the light along the thickness direction (Z-axis direction) of the electronic device 1000 into light perpendicular to the thickness direction (z-direction) of the electronic device 1000, so that each lens 321 of the lens assembly 320 and the imaging device in the camera module 300 are arranged inside the electronic device 1000 along a direction perpendicular to the thickness direction of the electronic device 1000. In this way, not only can telephoto shooting be achieved, but also the size in the thickness direction of the electronic device 1000 can be reduced.

[0128] Please refer to Figure 3As shown, the camera module 300 may include a camera component 310, a lens component 320, and an image sensor component 330. The three may be integrated inside the same protective case 30A. Of course, the camera component 310, the lens component 320, and the image sensor component 330 may also be separately installed in the electronic device 1000. The camera component 310, the lens component 320, and the image sensor component 330 may be sequentially arranged along the optical path propagation direction of the camera module. That is to say, the camera component 310 may be arranged on the light incident side of the lens component 320, and the image sensor component 330 is arranged on the light exiting side of the lens component 320. Taking the camera module 300 as a rear camera as an example, the camera component 310 may be arranged corresponding to the light transmission hole 201 on the rear cover 200. External ambient light enters the camera component 310 through the light transmission hole 201. The camera component 310 reflects the light to the lens component 320. After the light is emitted from the lens component 320, it enters the image sensor component 330. The image sensor component 330 converts the optical signal into an electrical signal to realize the imaging function of the camera module 300.

[0129] Wherein, the optical path direction of the external ambient light incident on the camera component 310 is S. The optical path direction S is usually the thickness direction of the electronic device ( Figure 1 、 Figure 3 and Figure 4 the Z direction shown in), the light is reflected inside the camera component 310 and enters the lens component 320 in the outgoing optical path direction S1. The outgoing optical path direction S1 is usually the plane direction of the electronic device 1000. Therefore, the optical axis direction of the lens component 320 may be arranged along the plane direction of the electronic device 1000. In other words, the length direction of the lens component 320 may be arranged along the plane direction of the electronic device 1000. For example, the length direction of the lens component 320 may be the width direction of the electronic device 1000 (refer to Figure 1 the x direction in) or the length direction (refer to Figure 1 the y direction in). The camera module 300 can turn the optical path through the camera component 310 and arrange the lens component 320 along the plane direction where the electronic device 1000 is located. In this way, on the basis of 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.

[0130] Please continue to refer to Figure 4 As shown, the lens component 320 may include a lens barrel ( Figure 4 not shown in) and a plurality of lenses 321. The lens barrel serves as the basic support structure of the lens component 320. The lenses 321 are arranged inside the lens barrel, and the lenses 321 may be arranged at intervals along the axial direction of the lens barrel. Each of the lenses 321 may include a convex lens and a concave lens. Figure 4Although the shapes of the lenses 321 are not shown, it does not prevent those skilled in the art from understanding the lens assembly 320 described in this application. Each lens 321 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 321 can move along the optical axis direction of the lens assembly 320 to magnify and reduce the shooting target, realizing the optical zoom function of the camera module 300.

[0131] Of course, please refer to Figure 5 , in another embodiment, a front-end lens assembly 330 may also be provided on the light incident surface side of the camera assembly 310. The front-end lens assembly 330 may also include a lens barrel ( Figure 5 not shown in the figure) and multiple lenses 331. The lenses 331 may include convex lenses and concave lenses. Figure 5 Although the shapes of the lenses 331 are not shown, it does not prevent those skilled in the art from understanding the front-end lens assembly 330 of this application. The front-end lens assembly 330 may also be an optical zoom lens, or of course a fixed-focus lens.

[0132] Please refer to Figure 4 and Figure 5 , in the embodiment of this application, 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 the optical signal into an electrical signal and then transmits the electrical signal to the image processing chip 332 to obtain an image signal. After the light entering the lens assembly 320 passes through each lens 321, it irradiates the photosensitive surface of the image sensor 331. The image sensor 331 converts the optical image received on its photosensitive surface into an electrical signal proportional to the optical image. This electrical signal can be transmitted to the main circuit board 400 through the FPC by the image processing chip 332.

[0133] In some embodiments, the lens assembly 320 or the image sensor assembly 330 may also be equipped with a driving device ( Figure 4 and Figure 5 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 direction or rotate at an angle around the optical axis of the lens assembly 320 to compensate for the displacement caused by the user's hand shake, prevent the captured image from being blurred, improve the clarity of the image, and realize the optical image stabilization function of the camera module 300. Please refer toFigure 6 In the embodiment of the present 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 (see Figure 7 As shown). Among them, the prism 1, the first mounting body 2, the second mounting body 3 and the base 4 are installed in the inner cavity 53 of the shell 5, and the shell 5 can protect the various components installed therein. In order to allow light to be irradiated onto the prism 1, the shell 5 has a avoidance opening corresponding to the light input surface 11 and the light output surface 12 of the prism 1. For example, the shell 5 has a light input port 51 and a light output port 52, which are respectively opposite to the light input surface 11 and the light output surface 12 of the prism. The light input port 51 and the light output port 52 can be respectively arranged on adjacent side walls of the shell 5, and the two can be connected or not connected. In order to improve the installation efficiency of the shell 5 and other components, a positioning column 46 can also be provided on the base 4. The specific structure of the shell 5 is not described in detail in this article.

[0134] See Figure 7 , Figure 7 for Figure 6 In the AA cross-sectional view, in the embodiment of the present application, the prism 1 is an optical element, having at least a light-input surface 11, a light-output surface 12 and a refractive surface 13, which can realize the turning of the light path. The prism 1 can be one, or of course, two or more. The prism can be a triangular prism, and the cross-section of the triangular prism is a right triangle. Of course, the prism can also be in other structural forms, as long as it can meet the requirements of light path propagation. The triangular prism has a simple structure, is light in weight and occupies a small space, which is conducive to meeting the miniaturization design requirements of the camera module 300. This application continues to introduce the technical solution by taking the prism 1 as an example of a triangular prism. The light-input surface 11, the light-output surface 12 and the refractive surface 13 of the triangular prism are connected end to end. It can be considered that the light-input surface 11 and the light-output surface 13 are adjacent, and the refractive surface 13 is connected to the light-input surface 11 and the light-output surface 12. The first mounting body 2 has a support surface 24 for fixing the prism. The refractive surface 13 of the prism 1 can be supported on the support surface 24, and the two can be fitted together. Please combine Figure 8 It is understood that both end faces 14 of prism 1 can be adhesively fixed to first mounting body 2 to improve the reliability of prism fixation. For example, adhesive grooves 3C can be provided on both side faces 25 of first mounting body 2, and liquid adhesive can be injected from adhesive grooves 3C between side faces 25 of first mounting body 2 and prism 1. The adhesive can be liquid adhesive or structural adhesive.

[0135] Combine Figure 4It is understood that the light incident surface 11 of the prism 1 corresponds to the light transmissive area of the electronic device 1000. For example, the light incident surface 11 of the prism 1 faces the light transmissive hole 201 of the rear cover 200 of the electronic device 1000. The light exit surface 12 of the prism 1 corresponds to the light incident side of the lens assembly 320. In this way, the light outside the electronic device 1000 irradiates the light incident surface 11 of the prism along the direction S, and after being reflected inside the prism 1, it exits from the light exit surface 12 of the prism 1 along the direction S1 to enter the light incident hole of the lens assembly 320. Taking the prism 1 as a right triangular prism as an example, the direction S1 and the direction S are perpendicular to each other.

[0136] Please refer to Figure 7 and Figure 8 , in the embodiment of the present application, the first mounting body 2 is rotatably mounted to the second mounting body 3 through the first rotating shaft 9. That is to say, the first mounting body 2 can rotate relative to the second mounting body 3 about the first rotating shaft 9. The axial direction of the first rotating shaft 9 is along the y direction. For the sake of simplicity in describing the technical solution, the axial direction of the first rotating shaft 9 in the embodiment of the present application is defined as the first direction, and the first direction is Figure 8 the y direction marked in Figure 9 . It is understood in combination with Figure 9 and Figure 10 that the second mounting body 3 can be generally a frame structure. Please refer to

[0137] In the embodiment of the present application, 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 or the like. The first rotating shaft 9 is rotationally supported by the second mounting body 3. Exemplarily, mounting holes can be provided on the second mounting body 3, and the first rotating shaft 9 is rotatably mounted in the mounting holes.

[0138] Please combine with Figure 7 , Figure 8 and Figure 9 to understand that in the embodiment of the present application, the camera assembly 310 further includes a first driving member 7. The first driving member 7 can drive the first mounting body 2 to rotate relative to the second mounting body 3 about the first direction (y-axis), and at the same time, the prism 1 rotates with the first mounting body 2 about the first direction, wherein Figure 10 the dotted double arrow in

[0139] is the rotation direction of reciprocating rotation about the y-axis. That is to say, the first driving member 7 can drive the first mounting body 2 to rotate in the first plane, and the first plane is a plane perpendicular to the first direction (y-axis). In this way, the light incident surface 11 and the light exit surface 12 of the prism deflect around the y-axis, and the positions and angles of the light incident surface 11 and the light exit surface 12 of the prism are adjusted along the deflection direction. Figure 8 and Figure 10, in the embodiments of the present application, the first driving component 7 may 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 rotation of the first mounting body 2 around the first direction is realized by closed-loop control through the first chip 73. The number of magnets in the first magnet assembly 72 may be one or more than two. Figure 8 shows that a first magnet assembly 72 includes two magnets, namely a first magnet 721 and a second magnet 722. The magnetic poles of the first magnet 721 and the second magnet 722 on the side facing the first electromagnetic coil 71 are different, that is, one is the N pole and the other is the S pole.

[0140] Please refer to Figure 7 、 Figure 10 and Figure 11 , the first magnet assembly 72 is fixed to the side wall of the first mounting body 2 facing 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 bonding. When installing, a colloid can be coated on the surface of the first magnet assembly 72 and the wall of the mounting groove of the first mounting body 2. To improve the fixing reliability of the first magnet assembly 72, a glue groove 3C can also be provided on the first mounting body 2, and the liquid glue is further filled between the first magnet assembly 72 and the second mounting body 2 through the glue groove 3C.

[0141] Please combine Figure 10 and Figure 12 to understand that the first electromagnetic coil 71 can be fixed to the base 4 or the second mounting body 3, and the first electromagnetic coil 71 is disposed opposite to the first magnet assembly 72. The drawings of the present application show a specific implementation manner in which the first electromagnetic coil 71 is fixed to the second mounting body 3. For specific technical effects, please refer to the description below. The electrical connection wires of the first electromagnetic coil 71 are connected to the circuit board outside the camera assembly 310 through the flexible circuit board assembly 6. When the first electromagnetic coil 71 is energized, a magnetic force of attraction or repulsion is generated between the first magnet assembly 72 and the first electromagnetic coil 71, thereby driving the first mounting body 2 to rotate relative to the second mounting body 3 around the first direction.

[0142] In this embodiment, the force for driving the rotation of the first mounting body 2 is provided by the cooperation of the coil and the magnet. The structure is relatively simple, and the magnitude of the current passing through the coil is controllable, with high adjustment flexibility and high adjustment accuracy.

[0143] To minimize the thickness of the camera assembly 310 as much as possible, the first magnet assembly 72 and the first electromagnetic coil 71 are arranged along the third direction ( Figure 10 the x-axis in Figure 13, along the third direction, there is a first opening 3-41 between the first side wall 3-1 and the second side wall 3-2 of the second mounting body 3, and the first magnet assembly 72 and the first electromagnetic coil 71 are located between the first side wall 3-1 and the second side wall 3-2. In one example, in order to balance the fixing requirements of the first electromagnetic coil 71 and the strength of the second mounting body 3, a third side wall 3-4 is connected between the first side wall 3-1 and the second side wall 3-2, and the first opening 3-41 is provided on the third side wall 3-4. In this way, the distance between the first magnet assembly 72 and the first electromagnetic coil 71 is relatively close, which is beneficial to reducing the size of the camera assembly 310 along the third direction, and there is no intermediate obstacle between the first electromagnetic coil 71 and the first magnet assembly 72, and the magnetic field strength generated by the first electromagnetic coil 71 will not be weakened, and a larger driving force can be provided with a smaller coil volume, which is beneficial to the miniaturized design of the camera assembly 310.

[0144] In the embodiment of the present application, the first electromagnetic coil 71 is installed on the second mounting body 3 and can rotate relative to the base 4 around the Z axis with the second mounting body 3. In this way, the distance between the first electromagnetic coil 71 and the first magnet assembly 72 will not change due to the rotation of the second mounting body 3 around the Z axis, and further reduce the influence of the rotation of the second mounting body 3 around the Z axis on the rotation of the first mounting body 1 around the x direction.

[0145] In the embodiment of the present application, the first mounting body 2 mainly plays a role in supporting the prism 1. On the premise of meeting 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.

[0146] Please refer to Figure 14 and Figure 15 for understanding. In the embodiment of the present application, the first surface 21 of the first mounting body 2 facing away from the light incident surface 11 has a first concave cavity 211. The second mounting body 3 may further include a connecting wall 3-3. The connecting wall 3-3 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 facing away from the prism light incident surface 11. The second mounting body 3 is generally a frame structure. The connecting wall 3-3 has a first protruding portion 3-32. At least part of the first protruding portion 3-32 is located inside the first concave cavity 211, and the first protruding portion 3-32 may be completely or partially located inside the first concave cavity 211. The side surface of the first protruding portion 3-32 facing the first mounting body 2 may be a plane, and the processing technology is simple. The second rotating shaft 41 is at least partially disposed on the first protruding portion 3-32. In this embodiment, the first concave cavity 211 can provide an avoidance space for the installation of the first protruding portion 3-32, which is beneficial to reducing the size of the camera assembly 310 along the first direction, and the first mounting concave portion 3-321 for accommodating part of the first rolling body 44' is provided on the first protruding portion 3-32, which can improve the strength of the cooperation position between the second mounting body 3 and the first rolling body 44'.

[0147] Please combine Figure 15 , Figure 15 The z direction shown in is the second direction. In the embodiment of the present application, the base 4 is located on the side of the second mounting body 3 away from 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 camera assembly 310 also includes a first rolling body 44', and the connecting wall 3-3 is movably supported on the base 4 through the first rolling body 44'. In this embodiment, the second mounting body 3 has a relatively simple structure, which is conducive to the lightweight design requirements of the camera assembly 310. Please refer to Figure 15-1 , at least part of the surface of the first rolling body 44' is a spherical portion. In order to describe the technical solution concisely, this application defines the spherical portion of the first rolling body 44' as a first spherical portion 441'. The first rolling body 44' can be a spherical structure, such as a ball. Of course, the first rolling body 44' can also be a hemispherical structure. The second mounting body 3 is supported on the base 4 and is rotatably mounted with the base 4 through the first spherical portion 441' of the first rolling body 44'. In order to minimize wear and increase the service life of the camera assembly 310, a metal body can be fixed to both the base 4 and the second mounting body 3. For example, a metal seat 3F is fixed to the second mounting body 3 or the base 4, and the metal seat 3F is provided with a recess that cooperates with the first rolling body 44'. For example, the metal seat 3F fixed on the second mounting body 3 has a first mounting recess 3-321, please refer to Figure 14 and Figure 15-1 . The metal seat 3F fixed on the base 4 has a second mounting recess 452, and the first rolling body 44' is partially located inside the first mounting recess 3-321 and partially located inside the second mounting recess 452. The first mounting recess 3-321 and the second mounting recess 452 are opened relative to each other, and the two can be hemispherical surfaces, that is, the entire inner surface of the first mounting recess 3-321 and the second mounting recess 452 have a surface that rotates with the first rolling body 44'. Of course, the first mounting recess 3-321 and the second mounting recess 452 can also partially cooperate with the first rolling body 44' on the inner surface, for example, the first mounting recess 3-321 is in line contact with the first rolling body 44', and the second mounting recess 452 is in line contact with the first rolling body 44'.

[0148] in Figure 15-1 As shown in FIG, the inner walls of the first mounting recess 3-321 and the second mounting recess 452 are not completely spherical, and both are in line contact with the first rolling element 44' located therein. Figure 15-1The positions indicated by the arrows are the annular contact positions of the first mounting recess 3-321 and the first rolling element 44', and the annular contact position of the second mounting recess 452 and the first rolling element 44'. The first mounting recess 3-321 and the second mounting recess 452 can be set to a substantially V-shaped structure. The first mounting recess 3-321 is a V-shaped structure with an opening facing downward, and the second mounting recess 452 is a V-shaped structure with an opening facing upward. In this way, the mounting stability of the first ball is relatively high and the friction is small.

[0149] In the embodiment of the present application, both the first rolling element 44' and the first bushing 32 can be metal parts, which are high in strength and wear-resistant.

[0150] Please refer to Figure 14 and Figure 15 , in the embodiment of the present application, the camera assembly 310 further includes a second driving member 8. The second driving member 8 can drive the second mounting body 3 to rotate relative to the base 4, and under the action of the first spherical surface portion 441', the second mounting body 3 can rotate around the second direction (z direction). That is to say, the second driving member 8 can drive the whole formed by the second mounting body 3 and the first mounting body 2 to rotate in the second plane, and the second plane is a plane perpendicular to the z-axis (second direction). In this way, the light incident surface 11 and the light exit surface 12 of the prism can deflect around the second direction (z direction), and the positions and angles of the light incident surface 11 and the light exit surface 12 of the prism can be adjusted along the deflection direction.

[0151] Figure 14 and Figure 15 It is shown in Figure 14 and Figure 13 that the camera assembly 310 is provided with two second driving members 8, so as to improve the driving force as much as possible. Specifically, the two second driving members 8 are respectively located on both sides of the second mounting body 3 along the first direction. Specifically, the two second driving members 8 are respectively located on both sides of the first rotating shaft 9, and the two can be symmetrically mounted. The second driving member 8 can also be a coil-magnet assembly. Combining Figure 13It can be seen that the magnetic pole on the side of the third magnet 822 facing away from the first side wall 3-1 is the S pole, and the magnetic pole on the side of the fourth magnet 821 facing away from the first side wall 3-1 is the N pole. In this way, when the second electromagnetic coil 81 is energized, a relatively large 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 that described in this article.

[0152] Please refer to comprehensively Figure 14 、 Figure 15 and Figure 16 for understanding. The camera assembly 310 further includes a magnetic adsorption assembly 37. The magnetic adsorption assembly includes a fifth element 371 and a sixth element 372 ( Figure 16 not shown in the figure), which are respectively disposed on the connecting wall 3-3 and the first mounting body 2. The fifth element 371 and the sixth element 372 attract each other in the second direction, and can provide a force for the relative combination of the first mounting body 2 and the second mounting body 3 in the second direction, improving the system stability. One of the fifth element 371 and the sixth element 372 can be a magnet, and the other can be a metal (such as iron) that can be attracted by the magnet. Of course, both the fifth element 371 and the sixth element 372 can be magnets.

[0153] Please refer to Figure 16 and Figure 17 for understanding. In the embodiment of the present application, a first elastic body 3D can be installed in some regions of the gap between the second mounting body 3 and the base 4. The first elastic body 3D can be an elastic glue, or a foam or other components that are prone to elastic deformation. In this way, the first elastic body 3D can not only improve the installation stability of the second mounting body 3 in the base 4, but also does not affect the rotation of the second mounting body 3 around the second direction. Similarly, a first elastic body 3D can also be installed in some regions of the gap between the first mounting body 2 and the second mounting body 3.

[0154] Please refer to again Figure 13 , in one example, the second mounting body 3 includes a first side wall 3-1 and a second side wall 3-2 arranged at intervals in the first direction, and a third side wall 3-4 is connected between the first side wall 3-1 and the second side wall 3-2. Two second driving components 8 are respectively disposed at the positions of the first side wall 3-1 and the second side wall 3-2. As Figure 16 shown, the base 4 includes a first frame side wall 4-1 and a second frame side wall 4-2. The first frame side wall 4-1 is disposed opposite to the first side wall 3-1 of the second mounting body 3, and the second frame side wall 4-2 is disposed opposite to the second side wall 3-2 of the second mounting body 3. Second electromagnetic coils 81 are provided on both the first frame side wall 4-1 and the second frame side wall 4-2. The structures of installing the second electromagnetic coils 81 on the two frame side walls can be the same or different. Please combine Figure 19It is understood that the present application provides an example in which the first frame side wall 4-1 and the second frame side wall 4-2 are provided with different mounting structures. Third mounting holes 4-22 are provided on the first frame side wall 4-1 and the second frame side wall 4-2, and the second electromagnetic coil 81 is mounted in the third mounting holes 4-22. The third mounting holes 4-22 can be through holes. Second magnet assemblies 82 are provided on both the first side wall 3-1 and the second side wall 3-2. In this embodiment, the second electromagnetic coil 81 is provided on the base 4, which is convenient for connection with the flexible circuit board.

[0155] Of course, in the embodiments of the present application, the second electromagnetic coil 81 and the second magnet assembly 82 can also be respectively provided on the opposite surfaces of the second mounting body 3 and the base 4, and there is no other structure blocking between the second electromagnetic coil 81 and the second magnet assembly 82, so as to avoid weakening the acting force between the two.

[0156] As can be seen from the above description, in the implementation of the present application, the first rotating shaft 9 is connected between the first mounting body 2 and the second mounting body 3, and the first driving member 7 drives the first mounting body 2 to rotate around the first rotating shaft 9, so as to realize the rotation of the prism 1 around the first direction. A first rolling body 44' is provided between the second mounting body 3 and the base 4. Under the action of the first rolling body 44', the second driving member 8 can drive the second mounting body 3 to rotate relative to the base 4 around the second direction, so as to realize the rotation of the prism 1 around the second direction. In this way, according to the shaking direction and shaking angle of the electronic device 1000, the first mounting body 2 can be driven to rotate around the first rotating shaft 9, or / and the second mounting body 3 can be driven to rotate relative to the base 4, so as to compensate for the shaking amount of the electronic device 1000. Since the first rotating shaft 9 and the first rolling body 44' are separately provided, the rotation adjustments of the prism 1 around the first direction and the second direction do not interfere with each other, improving the adjustment accuracy of the camera assembly 310 and making the control relatively simple.

[0157] Please refer to again Figure 14 , in the embodiments of the present application, the second surface 3-33 of the connecting wall 3-3 facing away from the first mounting body 2 has a second concave cavity 3-31. In combination with Figure 15 It is understood that the base 4 has a second protruding portion 45, at least a part of the second protruding portion 45 is located in the second concave cavity 3-31, the second protruding portion 45 is provided with a second mounting recess 452, and a part of the first rolling body 44' is located in the second mounting recess 452. In this embodiment, the thickness of the second protruding portion 45 is relatively large, which can improve the strength of the setting position of the first rolling body 44'. And a second concave cavity 3-31 is provided on the surface of the second mounting body 3 opposite to the second protruding portion 45. The second concave cavity 3-31 can provide an installation space for the second protruding portion 45, taking into account both the reliability of the use strength and the small volume.

[0158] The shapes of the first convex portion 3-32, the second convex portion 45, the first concave cavity 211, and the second concave cavity 3-31 can be reasonably set according to the specific structure, as long as the above-mentioned usage functions can be satisfied.

[0159] As described above, also in order to improve the wear resistance of the first rolling element 44', in the embodiment of the present application, the first rolling element 44' can be matched with a metal seat 3F with relatively good wear resistance. The materials of the first rolling element 44' and the metal seat 3F can both be metal materials, such as copper. The metal seat 3F can be fixed to the first convex portion 3-32 or the second convex portion 45 by gluing or / and welding.

[0160] Please refer to Figure 18 , in a specific example, metal bodies are fixed at the positions of both the first convex portion 3-32 and the second convex portion 45. The metal bodies can be fixed to the first convex portion 3-32 and the second convex portion 45 through an injection molding process. In the embodiment of the present application, the metal body fixed to the first convex portion 3-32 is defined as the first metal body 33, and the metal body fixed to the second convex portion 45 is defined as the second metal body 43. The metal seat 3F on the first convex portion 3-32 is fixedly welded to the first metal body 33, and the metal seat 3F on the second convex portion 45 is fixedly welded to the second metal body 43. A part of the first metal body 33 is exposed outside the first convex portion 3-32, and welding through holes 3E are provided for fixedly welding with the metal seat 3F in the first convex portion 3-32. Similarly, a part of the second metal body 43 can be exposed outside the second convex portion 45, and welding through holes 3E are provided for fixedly welding with the metal seat 3F in the second convex portion 45. Among them, the end of the metal seat 3F in the first convex portion 3-32 away from the second convex portion 45 is welded to the first metal body 33. The end of the metal seat 3F in the second convex portion 45 away from the first convex portion 3-32 is welded to the second metal body 43.

[0161] Similarly, in order to facilitate welding, welding through holes 3E can be provided on both the first metal body 33 and the second metal body 43.

[0162] Please refer to again Figure 18 , in the embodiment of the present application, the camera assembly 310 further includes a third element 38 and a fourth element (the fourth element is not shown in the figure). The third element 38 is located on the first side wall 3-1 or the second side wall 3-2, and the fourth element is located on the first mounting body 2. The third element and the fourth element attract or repel each other magnetically, so as to apply a force parallel to the first direction to the first mounting body 2. In this way, under the magnetic force of the third element 38 and the fourth element, the first mounting body 2 has a predetermined acting force on the second mounting body 3 in the first direction, and the first mounting body 2 can be prevented from moving axially in the first direction, and the stability of the camera assembly 310 is higher. Figure 18An embodiment is shown in which the third element is a permanent magnet. At this time, the fourth element can be a metal body, a permanent magnet, or an electromagnet fixed to the first mounting body 2. Of course, the third element can also be a metal. At this time, the fourth element is a permanent magnet or an electromagnet. The third element can also be other components such as an electromagnet. At this time, the fourth element can be a permanent magnet, an electromagnet, or a metal.

[0163] Please refer to Figure 19 for understanding. In one example, the base 4 further includes a third frame side wall 4-3 and a fourth frame side wall 4-4 connected between the first frame side wall 4-1 and the second frame side wall 4-2. The third frame side wall 4-3 is disposed opposite to the first magnet assembly 72. A second opening 401 can be formed on the third frame side wall 4-3 to facilitate the maintenance and installation of the first electromagnetic coil 71 connected to the second mounting body 3. A metal seat 3F is provided on the fourth frame side wall 4-4.

[0164] In the embodiment of the present application, the first mounting body 2 is rotationally supported by the first side wall 3-1 and the second side wall 3-2 of the second mounting body 3 through the first rotating shaft 9. In order to improve the coaxiality of the first rotating shafts 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 further made for the camera assembly 310 in the embodiment of the present application.

[0165] As Figure 19-1 shown, a through hole 23 is provided on the first mounting body 2. The first rotating shaft 9 penetrates through the first mounting body 2, and the two end shaft segments of the first rotating shaft 9 are located outside the through hole 23. Please refer to Figure 14 and Figure 15 for understanding. The camera assembly 310 further includes two first shaft sleeves 32. The two end shaft segments of the first rotating shaft 9 are respectively supported by the first shaft sleeves 32 on the first side wall 3-1 and the second side wall 3-2. The inner hole of the first shaft sleeve 32 rotates in cooperation with the first rotating shaft 9. On the one hand, this can reduce the processing difficulty of the first side wall 3-1 and the second side wall 3-2. On the other hand, the first shaft sleeve 32 can be made of a material different from that of the second mounting body 3. For example, the first shaft sleeve 32 uses a metal material with higher strength to improve the wear resistance of the first shaft sleeve 32 and the first rotating shaft 9.

[0166] Refer to Figure 15 , Figure 20 for understanding. In the embodiment of the present application, the first mounting hole 322 on the first shaft sleeve 32 is a through hole. A baffle 34 is fixed to the side wall of each first shaft sleeve 32 facing away from the first rotating shaft 9 (refer to Figure 21Understand), to block the port of the first mounting hole 322 away from the first rotating shaft 9. The first rotating shaft 9 is located between the two baffles 34. The baffle 34 can limit the displacement of the first rotating shaft 9 in the first direction to prevent the first rotating shaft 9 from disengaging from the first mounting hole 322. In this embodiment, the first mounting hole 322 on the first bushing 32 is a through hole, which is beneficial to improving the coaxiality of the first mounting hole 322 on the first bushing 32 on the first side wall 3-1 and the second side wall 3-2, and the processing technology is relatively simple.

[0167] In the embodiment of the present application, the first bushing 32 can be made of a wear-resistant material with a relatively low hardness. When the electronic device 1000 accidentally drops, the first rotating shaft 9 will impact the baffle 34. It is best for the baffle 34 to have a relatively high hardness so as to provide a relatively high impact resistance, thereby improving the impact resistance of the camera module 310. In the embodiment of the present application, the material hardness of the baffle 34 is greater than that of the first bushing 32. For example, the material of the first bushing 32 can be copper, and the material of the baffle 34 can be stainless steel. Of course, the baffle 34 can also be made of other metal materials with a hardness greater than that of copper.

[0168] Among them, the first bushing 32 can also be provided with a recess, and the baffle 34 is installed in the recess to reduce the occupation of space. The baffle 34 can also be provided with a welding through hole 3E, and the baffle 34 is fixedly welded to the first bushing 32.

[0169] Please refer to Figure 20 , in the embodiment of the present application, the first mounting hole 322 can be set as a non-circular hole. The hole wall of the first mounting hole 322 includes a first arc segment 3222, a second arc segment 3223, and two first inclined segments 3221 arranged at an angle. The two end portions of the first arc segment 3222 are connected to the second arc segment 3223 through the two first inclined segments 3221. The farther away from the central axis of the first mounting hole 322, the smaller the distance between the two first inclined segments 3221, and the outer wall of the end shaft segment is supported on the two first inclined segments 3221. That is to say, the two first inclined segments 3221 can be generally in a V-shaped structure. Of course, in another embodiment, the two first inclined segments 3221 can be directly connected, that is, the second arc segment 3223 does not need to be provided.

[0170] In this embodiment, the end shaft segment of the first rotating shaft 9 is supported on the two first inclined segments 3221, and the two first inclined segments 3221 can play a role in positioning the first rotating shaft 9, which is beneficial to improving the coaxiality of the first rotating shaft 9 installed on the two first bushings 32.

[0171] Similarly, in order to further improve the coaxiality after the installation of the first rotating shaft 9, in the embodiment of the present application, the first bushing 32 is further set to an irregular structure. The first bushing 32 includes a bottom surface 324 and two side surfaces 325. A second inclined surface segment 323 is connected between each side surface 325 and the bottom surface 324. The farther away from the central axis of the first mounting hole 322, the smaller the distance between the two second inclined surface segments 323. The first side wall or the second side wall has a receiving groove 36, and the receiving groove 36 has an inclined wall 361 that fits and cooperates with the two second inclined surface segments 323. In combination with Figure 18 Understand that the bottom surface 324 of the first bushing 32 abuts against the bottom wall 361 of the receiving groove 36. The first bushing 2 can be supported on the two inclined walls 361, and of course, it can also be supported on the bottom wall 361 at the same time.

[0172] In the embodiment of the present application, the structure in which the first bushing 32 is supported in cooperation with the receiving groove 36 is generally a V-shaped structure, which can accurately position the first bushing 32 and further improve the coaxiality of the two first bushings 32 installed on the second support 3.

[0173] The first bushing 32 can be fixed to the first side wall 3-1 or the second side wall 3-2 by gluing. Of course, in order to improve the fixing reliability between the first bushing 32 and the first side wall 3-1 or the second side wall 3-2, the first bushing 32 and the first side wall 3-1 or the second side wall 3-2 can be further fixed by welding. For example, a metal body 33 is injection-molded inside the first side wall 3-1 or the second side wall 3-2, and the first bushing 32 or / and the baffle 34 are welded and fixed to the first metal body 33. Among them, in order to facilitate welding, a welding through hole 3E is provided on the first metal body 33. And, 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 play a good role in isolating the first bushing 32 and the second magnet assembly 82, avoiding the collision between the first bushing 32 and the second magnet assembly 82 and damaging the second magnet assembly 82.

[0174] Please refer to Figure 19 and Figure 22 , in order to minimize the frictional force of the relative movement between the connecting wall 3-3 and the base 4, in the embodiment of the present application, the connecting wall 3-3 and the base 4 can also be in rolling contact through the second rolling balls 44. Specifically, at least one second rolling ball 44 is provided between the connecting wall 3-3 and the base 4, and the connecting wall 3-3 is supported on the base 4 through the second rolling balls 44. The second rolling balls 44 are located in the circumferential direction of the second protrusion 45.

[0175] The number of the second rolling balls 44 can be one or more than two. Figure 19An example in which there are two second balls 44 is shown. The two second balls 44 and a first rolling body 44' are arranged in a triangle, and the support stability is relatively high. Among them, the two second balls 44 are located between the first rolling body 44' and the side wall of the third frame, with relatively high support stability and a compact structure.

[0176] In a specific example, concave surfaces 3-3A (shown in Figure 22 ) can also be provided on both the base 4 and the connecting wall 3-3. The second ball 44 is located inside the concave surface 3-3A. The concave surface 3-3A defines the movement range of the second ball 44 and can further improve the installation stability of the second ball 44.

[0177] 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. In order to improve the support strength between the connecting wall 3-3 and the second ball 44, and between the base 4 and the second ball 44, the second ball 44 can be in rolling contact with the first metal body 33 and the second metal body 43. That is to say, the second ball 44 is located between the metal body of the connecting wall 3-3 and the metal body of the base 4.

[0178] In order to improve the installation stability of the second installation body 3 in the initial installation position and enable it to quickly return to the initial installation position after the second electromagnetic coil 81 is powered off, the camera assembly 310 can also include a holding mechanism that is partially connected to the second installation body 3 and partially connected to the base 4, and is used to provide a restoring force for the second installation body 3 to return to the initial installation position. The so-called initial installation position of the second installation body 3 refers to the position of the second installation body 3 in the initial assembled state of the camera assembly 310, or the position of the second installation body 3 in the standard state of the camera assembly 310, or the position of the second installation body 3 when the second electromagnetic coil 81 in the camera assembly 310 is in the powered-off state. The following gives several implementation manners in which the holding mechanism includes a spring piece, a magnetic reset unit 35, and an elastic body.

[0179] Please refer to Figure 15 , Figure 18 , Figure 19 and Figure 22 to understand that the holding mechanism can also include at least one magnetic reset unit 35. The magnetic reset unit 35 includes a first element 351 and a second element 352. The first element 351 is provided on the second installation body 3, and the second element 352 is provided on the base 4. The first element 351 and the second element 352 are configured to provide a structure for the first installation body 2 to maintain or / and restore to the initial position restoring force. One of the first element 351 and the second element 352 can be a magnet, and the other can be a metal (such as iron) that can be attracted by the magnet. Of course, both the first element 351 and the second element 352 can also be magnets.

[0180] The first component 351 and the second component 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 acting 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 the initial position to a certain extent.

[0181] Please refer to Figure 11 and Figure 25 , in the embodiment of the present application, the camera assembly 310 further includes a first elastic sheet 22. The first elastic sheet 22 connects the first mounting body 2 and the second mounting body 3, and the first elastic sheet 22 is configured in a shape that can provide a restoring force for the first mounting body 2 to return to the initial mounting position. The so-called initial mounting position of the first mounting body 2 refers to the position of the first mounting body 2 in the initial assembled 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 the de-energized state. Similarly, in the embodiment of the present application, the initial position of the second mounting body 3 also refers to the position of the second mounting body 33 in the initial assembled state of the camera assembly 310, or the position of the second mounting body 33 in the standard state of the camera assembly 310, or the position of the second mounting body 3 when the second electromagnetic coil 81 in the camera assembly 310 is in the de-energized state. The first elastic sheet 22 can be a metal sheet with one or more bending structures. Under the action of an external force, the metal sheet will deform and generate a restoring force. When the first mounting body 2 is located at the initial mounting position, the first elastic sheet 22 can be in the original state. At this time, the first elastic sheet 22 is not affected by an external force and has no deformation. When the first electromagnetic coil 71 is energized, the first mounting body 2 rotates around the first rotating shaft, and at the same time drives the first elastic sheet 22 to move relative to the second mounting body 3. The first elastic sheet 22 deforms, and thus generates a restoring force. After the first electromagnetic coil 71 is de-energized, under the action of the restoring force of the first elastic sheet 22, the first mounting body 2 can quickly return to the initial mounting position. In this embodiment, the elastic sheet occupies a relatively small space.

[0182] Please refer to again Figure 11 , on the same side of the first mounting body 2 and the second mounting body 3 ( Figure 11 as shown in

[0183] Please refer to Figure 16 and Figure 25, in the embodiments of the present application, the holding mechanism may further include a second elastic piece 42. The second elastic piece 42 is connected to the second mounting body 3 and the base 4 at the same time. The mounting method of the second elastic piece 42 is the same as that of the first elastic piece 22, and it can be fixedly installed through the cooperation of the convex post 3A and the through hole. The second elastic piece 42 can provide a restoring force for the second mounting body 3 to return to the initial mounting position.

[0184] In addition, by reasonably setting the shape of the second elastic piece 42, the second elastic piece 42 can also provide a abutting force for the second mounting body 3 to abut against the base 4 along the second direction, so that the second mounting body 3 can be stably supported on the base 4.

[0185] Please refer to Figure 11 for understanding. In the embodiments of the present application, the camera assembly 310 may also be provided with at least one ferromagnetic body 10, Figure 11 as shown in, the ferromagnetic body 10 is installed on the side of the first electromagnetic coil 71 away from the first magnet assembly 72, and the ferromagnetic body 10 can be installed on the support plate 62 ( Figure 11 not shown in the figure). The ferromagnetic body 10 and the first electromagnetic coil 71 are located on the support plate 62, and there is an attractive force between the first magnet assembly 72 and the ferromagnetic body 10. The ferromagnetic body 10 can be a material containing iron, such as steel, or it can also be a magnet. The ferromagnetic body 10 and the first magnet assembly 72 attract each other, which is beneficial for the first mounting body 2 to maintain or / and return to the initial mounting position.

[0186] The mutual attraction between the first magnet assembly 72 and the ferromagnetic body 10 can improve the mounting stability of the first mounting body 2 to a certain extent. When the first electromagnetic coil 71 is energized, the acting force generated by the first electromagnetic coil 71 and the first magnet assembly 72 can overcome the attractive force between the first magnet assembly 72 and the ferromagnetic body 10, and drive the first mounting body 2 to rotate relative to the second mounting body 3. When the first electromagnetic coil 71 is powered off, the attractive force between the first magnet assembly 72 and the ferromagnetic body 10 can provide a restoring force for the first mounting body 2 to return to the initial mounting position to a certain extent.

[0187] In the embodiments of the present application, by using the first magnet assembly 72 in the first driving component 7, only the ferromagnetic body 10 needs to be installed on the base 4, which occupies a small space and is convenient to install.

[0188] Please refer to Figure 12 and Figure 24 for understanding. In the embodiments of the present application, the camera assembly 310 further includes a flexible circuit board assembly 6. The flexible circuit board assembly 6 includes a flexible circuit board 61 and a support plate 62. The flexible circuit board 61 has a first main body portion 611. The support plate 62 includes a first support portion 621. The first main body portion 611 and the first electromagnetic coil 71 are connected to the second mounting body 3 through the first support portion 621, and the first electromagnetic coil 71 is electrically connected to the first main body portion 611. This fixing method is simple and convenient.

[0189] In the embodiment of the present application, the flexible circuit board further includes a second main body portion 612 and a connecting section 613. The second main body portion 612 is connected to the base 4, and the first main body portion 611 is connected to the second main body portion 612 through the connecting section 613. The attitude of the connecting section 613 can change with the rotation of the second mounting body 3, and the attitude of the connecting section 613 can change with the second mounting body 3. The connecting section 613 is a free section and can adapt to the change in the position of the second mounting body 3.

[0190] In the embodiment of the present application, the second main body portion 612 can also include a plurality of sections, such as the sections fixed on the first frame side wall 4-1, the second frame side wall 4-2, and the fourth frame side wall 4-4 of the base 4. The flexible circuit board 61 is also electrically connected to the second electromagnetic coil 81. The external connection end 610 where the flexible circuit board 61 is electrically connected to the external circuit is located outside the housing 5. Please refer to Figure 6 .

[0191] In the embodiment of the present application, the support plate 62 can be in a split form. For example, the support plate 62 is provided on one or several sides of the base 4 facing 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. And the support plate 62 located on one side of the fourth frame side wall 4-4 of the base 4 can directly close the opening on this side of the housing 5 and serve as a part of the housing 5 (please refer to Figure 7 ), and the weight of the camera assembly 310 is minimized as much as possible.

[0192] Embodiment 2

[0193] Please refer to Figure 26 , another embodiment of the camera assembly 310 is provided in the embodiment of the present application. From the appearance, the camera assembly 310 in the embodiment of the present application is substantially the same as that in Embodiment 1. The structure of the camera assembly 310 disclosed in the embodiment of the present application is Figures 6 to 25 substantially the same as the functions that can be achieved by the camera assembly 310 disclosed in Figure 27 . In the embodiment of the present application, the main structure of the camera assembly 310 also includes a housing, a prism 1, a first mounting body 2, a second mounting body 3, a base 4, a first driving member 7, a second driving member 8, and an FPC. The main structures of the above components are basically the same as those described above regarding Figures 6 to 25 , especially the structures of the housing, the prism 1, the first rolling body, and the FPC are Figures 6 to 25 substantially identical. Please refer to the relevant content in Embodiment 1, and this embodiment will not be described in detail.

[0194] In terms of structure, the biggest difference between the embodiment of the present application and Embodiment 1 lies in: Figures 26 to 42In the camera component 310, the first mounting body 2 is rollingly supported on the second mounting body 3 by the second rolling elements 26.

[0195] The following will describe in detail around the differences. For the Figures 6 to 25 structures that are the same or similar, they will be briefly described below, and the specific content can refer to the description of the corresponding structures above. Figures 6 to 25 in the above text.

[0196] In the embodiment of the present application, Figure 28 a specific embodiment in which the second rolling elements 26 are balls is shown. For the convenience of description, the balls of the second rolling elements 26 in the present application are defined as the third balls. The ball structure is simple and easy to install. The first mounting body 2 is supported on the second mounting body 3, and the first mounting body 2 is rotatably mounted on the second mounting body 3 through the third balls so as to be able to rotate relative to the second mounting body 3 around the first direction. Please refer to Figure 30 the assembly schematic diagram of the first mounting body 2 and the second mounting body 3.

[0197] In addition to being in the form of balls, the second rolling elements 26 can also be in other forms, such as a hemispherical structure. That is to say, at least part of the surface of the second rolling elements 26 is a spherical surface portion. For the simplicity of describing the technical solution, the spherical surface portion of the second rolling elements 26 in the present application is defined as the second spherical surface portion. The first mounting body 2 is rotatably supported on the second mounting body 3 through the second spherical surface portion. The first mounting body 2 is supported on the second mounting body 3, and the first mounting body 2 is rotatably mounted on the second mounting body 3 through the second spherical surface portion so as to be able to rotate relative to the second mounting body 3 around the first direction.

[0198] Please combine with Figure 28 As shown in, the first mounting body 2 has a first surface 21 facing away from the light incident surface. The first surface 21 has a first concave cavity 211. The first concave cavity 211 has a third opening facing the second mounting body 3. The first concave cavity 211 further includes a top wall 212 opposite to the third opening. Please refer to Figure 29, the second mounting body 3 includes a first side wall 3-1, a second side wall 3-2, and a connecting wall 3-3. A support platform 3-34 is provided on the connecting wall 3-3. At least part of the support platform 3-34 is located inside the first concave cavity 211. The third ball (the second rolling body 26) is located between the top wall 212 and the support platform 3-34. Since part of the support platform 3-34 is located inside the first concave cavity 211, the structures of the second mounting body 3 and the first mounting body 2 are relatively compact, which is conducive to the miniaturization of the camera assembly 310. Among them, the number of the third balls can be two, and the two third balls are arranged at intervals in the first direction. The support platforms 3-34 on the second mounting body 3 correspond to the third balls one by one, that is, two support platforms 3-34 are also provided on the second mounting body 3, and the two support platforms 3-34 are respectively located at both ends of the connecting wall 3-3 in the first direction. In this way, the distance between the two support platforms 3-34 in the first direction is relatively large, so that the distance between the two third balls can be as far as possible, and the support stability for the first mounting body 2 is relatively high.

[0199] Please refer to comprehensively Figure 28 and Figure 29 , in the embodiment of the present application, the top wall 212 has a receiving cavity 3-35 for the rotational fit of the third ball, and the support platform 3-34 also has a receiving cavity 3-35 for the rotational fit of the third ball. The two receiving cavities 3-35 corresponding to the top wall 212 and the support platform 3-34 enclose a space for receiving the third ball. The cavity wall of the receiving cavity 3-35 on the support platform 3-34 and the third ball, and the cavity wall of the receiving cavity 3-35 on the top wall 212 and the third ball can be in surface contact, that is, the cavity wall of the receiving cavity 3-35 on the support platform 3-34 can be a part of a spherical surface, and the cavity wall of the receiving cavity 3-35 on the top wall 212 can also be a part of a spherical surface. Of course, the cavity wall of the receiving cavity 3-35 on the support platform 3-34 and the third ball, and the cavity wall of the receiving cavity 3-35 on the top wall 212 and the third ball can also be in line contact. The specific structure of the receiving cavity 3-35 can refer to the structures of the first mounting recess 3-321 and the second mounting recess 452 in Embodiment 1. This structure is conducive to the coaxial installation of the third ball with the receiving cavity 3-35 of the support platform 3-34 and the receiving cavity 3-35 on the top wall 212.

[0200] Furthermore, the cavity wall of the receiving cavity 3-35 on the support platform 3-34 and the third ball, and the cavity wall of the receiving cavity 3-35 on the top wall 212 and the third ball can also be in multi-point contact. The embodiment of the present application shows two structures of the receiving cavity 3-35: The first structure is: Please refer to Figure 30The accommodating cavity 3-35 has a cavity wall with three inclined surfaces 4A. The three inclined surfaces 4A form a tapered structure. The closer to the opening of the accommodating cavity 3-35, the larger the tapered structure. The three inclined surfaces 4A can be arranged at equal angles along the circumference, and the inclination angles and sizes of the inclined surfaces 4A are substantially the same. The third ball contacts all the inclined surfaces 4A in the accommodating cavity 3-35. The second structure is: See Figure 31 The accommodating cavity 3-35 has a cavity wall with two inclined surfaces on the cavity wall. The two inclined surfaces 4A are arranged opposite to each other, and their symmetry planes are parallel to the first direction. The two inclined surfaces form a V-shaped groove. The farther away from the opening position of the accommodating cavity 3-35, the smaller the distance between the two inclined surfaces 4A. The ends of the two inclined surfaces away from the opening of the accommodating cavity 3-35 can be connected, and of course they can also be connected through the middle section.

[0201] In the embodiment of the present application, the cavity wall of the accommodating cavity 3-35 abuts against the third ball at more than two points, which can effectively fix the third ball and effectively avoid the problem of pits in the third ball.

[0202] Please refer again Figure 28 、 Figure 29 It is understood that in the embodiment of the present application, except for one accommodating cavity 3-35 on the support platform 3-34 being set to the second structural form, the other three accommodating cavities 3-35 are set to the first structure, so that the accommodating cavity 3-35 of the first structure can constrain the relative positions of the first mounting body 2 and the second mounting body 3 in the second direction and the plane perpendicular to the second direction, that is, the number of constrained degrees of freedom is relatively large, which can improve the precise positioning of the relative positions of the first mounting body 2 and the second mounting body 3, while the accommodating cavity 3-35 of the second structure has relatively few constrained degrees of freedom, avoiding excessive positioning of the first mounting body 2 and the second mounting body 3.

[0203] Those skilled in the art should understand that the structure of the accommodating cavity 3-35 on the support platform 3-34 and the structure of the accommodating cavity 3-35 on the top wall 212 may be the same or different, and the structure of the accommodating cavity 3-35 may be any one of a part of the spherical surface mentioned above, a line-contact annular surface or a multi-point contact inclined surface.

[0204] In order to improve the use strength of the accommodating cavity 3-35, in the embodiment of the present application, the first mounting body 2 and the second mounting body 3 may have a metal insert 28 inside. Figure 30 and Figure 31 It is understood that the metal insert 28 can be pre-formed with the accommodating cavity 3-35 structure. The metal insert 28 is integrated with the first mounting body 2 or the second mounting body 3 through an injection molding process. The overall structure of the camera assembly 310 in this embodiment is also relatively high, improving the quality of the camera assembly 310.

[0205] The specific shape of the metal insert can be determined according to its location. This application shows the specific structure of two metal inserts. Please refer to Figure 30 The receiving cavity 3-35 on the first metal insert has three inclined surfaces 4A, forming a tapered receiving cavity 3-35 structure. Figure 31 The accommodating cavity 3-35 on the second metal insert has two inclined surfaces 4A, forming a V-shaped groove structure. Of course, the structure of the metal insert is not limited to the structure shown in this article, and can also be other shapes.

[0206] Please refer to Figure 32 、 Figure 33 and Figure 34 It is understood that in the embodiment of the present application, the support platform 3-34 is at least partially located inside the first cavity 211, the second mounting body 3 and the first mounting body 2 are partially embedded along the second direction, the second mounting body 3 has a relatively high supporting stability for the first mounting body 2, and the first mounting body 2 and the second mounting body 3 in the camera assembly 310 have a more compact structure, which can minimize the space occupied by the camera assembly 310, especially reduce the size of the camera assembly 310 along the second direction.

[0207] Please refer to Figure 36 , Figure 36 for Figure 35 In the embodiment of the present application, the driving force of the first mounting body 2 relative to the second mounting body 3 in the first direction also comes from the first driving component 7, which includes a first electromagnetic coil 71, a first magnet assembly 72 and a first chip 73. Figures 6 to 25 The difference from the disclosed structure is that in the embodiment of the present application, the first chip 73 is located outside the first electromagnetic coil 71, and the second elastic body 3M is installed at the middle through hole position of the first electromagnetic coil 71. The second elastic body 3M partially protrudes from the side of the first electromagnetic coil 71 facing the first magnet assembly 72, and the second elastic body 3M is connected to the first electromagnetic coil 71. Figure 37 Understand. Figure 36 Taking the example of the first electromagnetic coil 71 being mounted on the second mounting body 3 and the first magnet assembly 72 being mounted on the first mounting body 2, when the first mounting body 2 rotates in the first direction, the distance between the first mounting body 2 and the second mounting body 3 changes. Since the second elastic body 3M protrudes from the first electromagnetic coil 71, the first magnet assembly 72 first contacts the second elastic body 3M, thereby reducing the probability of collision between the first magnet assembly 72 and the first electromagnetic coil 71 and protecting the first electromagnetic coil 71. When the first electromagnetic coil 71 is mounted on the first mounting body 2 and the first magnet assembly 72 is mounted on the second mounting body 3, the second elastic body 3M mounted at the center through hole of the first electromagnetic coil 71 can also reduce the probability of collision between the first magnet assembly 72 and the first electromagnetic coil 71.

[0208] Installing the first chip 73 outside the central through-hole of the first electromagnetic coil 71 can also reduce the influence of the first electromagnetic coil 71 on the operation of the first chip 73.

[0209] Of course, the first chip 73 in this embodiment can also be arranged at the position of the central through-hole of the first electromagnetic coil 71, in the same arrangement manner as in Embodiment 1.

[0210] First driving component 7 In the embodiment of the present application, the power for the second mounting body 3 to rotate relative to the base 4 around the second direction also comes from the second driving component 8. The second driving component 8 includes a second electromagnetic coil 81, a second magnet assembly 82, and a second chip 83. Combining Figure 38 For understanding, the number of the second driving components 8 is two, and the two second driving components 8 are respectively located on one side of the first side wall 3-1 of the second mounting body 3 and on one side of the second side wall 3-2.

[0211] The structure of the second magnet assembly 82 can refer to the relevant description in Embodiment 1. Attached Figure 39 shows an example in which the second magnet assembly 82 includes a third magnet and a fourth magnet. Those skilled in the art should understand that as long as it can satisfy driving the second mounting body 3 to rotate relative to the base 4 around the second direction, the structures of the second magnet assembly 82 and the second electromagnetic coil 81 are not limited to the structures described herein.

[0212] Please refer to again Figure 37 , different from the Figures 6 to 25 public structure, in the embodiment of the present application, the second chip 83 is also located outside the central through-hole of the second electromagnetic coil 81. Please refer to Figure 37 (The second electromagnetic coil 81 and the second magnet assembly 82 at the position of the first side wall 3-1 are not shown). A second elastic body 3M is installed in the central through-hole of the second electromagnetic coil 81 to reduce the probability of the second electromagnetic coil 81 being impacted by the second magnet assembly 82.

[0213] Second magnet assembly 82 Second magnet assembly 82 Second mounting body 3 Base 4 Second magnet assembly 82 Second electromagnetic coil 81 Combining Figure 28 , Figure 29 and Figure 38 For understanding, in the embodiment of the present application, a first elastic sheet may not be provided between the first mounting body 2 and the second mounting body 3 (see Figure 11The first elastic piece 22), which can simplify the structure and assembly process of the camera module 310 and reduce the product cost. The force for maintaining or restoring the first mounting body 2, the second mounting body 3, the base 4 to the initial position can be provided only by the magnetic component, such as the magnetic adsorption component 37 described in Embodiment 1, and the third element and the fourth element (the third element and the fourth element are not shown in the drawings of Embodiment 2 and reference can be made to the content described in Embodiment 1). The shape and number of the magnetic components are not limited.

[0214] On the premise of realizing the above functions of the camera module 310, the first mounting body 2, the second mounting body 3, the base 4, the first driving component 7 and the second driving component 8 can be substantially the same as those in Embodiment 1, or slightly different from those in Embodiment 1. For example, please refer to Figure 39 , in the embodiment of the present application, the outer walls of the two side walls of the first mounting body 2 arranged at intervals in the first direction further have protrusions 27, and the protrusions 27 extend to the tops of the first side wall 3-1 or the second side wall 3-2 of the second mounting body 3, which can limit the rotation of the first mounting body 2. The corners of the first side wall 3-1 and the second side wall 3-2 of the second mounting body 3 have notches 301, and the protrusions 27 are partially located in the notches 301, so that while not hindering the rotation of the first mounting body 2 around the first axis, the rotation angle of the first mounting body 2 can be limited, and the overall structure is relatively compact and the volume is relatively small.

[0215] Similar to Embodiment 1, in the embodiment of the present application, the second mounting body 3 is connected to the base 4 through balls and can rotate relative to the base 4 around the second direction. The metal seats 3F on the second mounting body 3 and the base 4 that cooperate with the balls can have the same structure as the metal seats in Embodiment 1, or of course, can be different. Figures 40 to 42 Another embodiment of the metal seat 3F is given. Three inclined surfaces 4A are also provided on the metal seat 3F, and the balls are in contact with the metal seat 3F at three points, which is beneficial to the coaxial positioning and installation of the second mounting body 3 and the base 4, and has a good fixing effect on the balls. Of course, the metal seat 3F in the embodiment of the present application can also be provided with a spherical surface portion that is in surface contact and cooperation with the balls.

[0216] In the implementation of this application, under the driving force of the first driving component 7, the first mounting body 2 can rotate around the second rolling body 26 connected between the first mounting body 2 and the second mounting body 3, so that the prism 1 rotates around the first direction. Under the driving force of the second driving component 8, the second mounting body 3 can rotate around the first rolling body 44' connected between the second mounting body 3 and the base 4, so as to realize the rotation of the prism around the second direction. In this way, according to the jitter direction and jitter angle of the electronic device, the first mounting body 2 can be driven to rotate around the first direction, and / or the second mounting body 3 can be driven to rotate relative to the base 4 around the second direction, so as to compensate for the jitter amount of the electronic device. Since the second rolling body 26 and the first rolling body 44' are arranged between different components, that is, they are separately arranged, the rotation adjustment of the prism around the first direction and the second direction does not interfere with each other, which improves the adjustment accuracy of the camera assembly 310, and the control is relatively simple. In addition, the two components are connected by rolling of the rolling body, the movement flexibility is relatively high, the volume occupied by the rolling body is relatively small, and the weight is also relatively light.

[0217] Please refer to Figure 43 , in the embodiment of this application, the second elastic sheet may not be provided between the second mounting body 3 and the base 4 (see the second elastic sheet 42 in Figure 16 ), which further simplifies the structure and assembly process of the camera assembly. The restoring force for the second mounting body 3 to maintain or / and return to the initial position can be provided by the magnetic reset unit 35. For the setting position and structure of the magnetic reset unit 35, please refer to Figure 38 . The specific structure of the magnetic reset unit 35 can refer to the description in Embodiment 1.

[0218] The camera module 300 and the electronic device 1000 provided in the embodiment of this application both include the above-mentioned camera assembly 310.
