Abstract
Description
[0001] This application is a divisional application filed on March 20, 2025, with application number 2025103395006, entitled "A camera assembly, camera module and electronic device". Technical Field
[0002] This application relates to the field of camera technology, and more particularly to a camera assembly, camera module, and electronic device. Background Technology
[0003] Electronic devices typically incorporate camera modules to meet the needs of capturing images or videos. To balance the requirements of ultra-thin designs and telephoto shooting in electronic devices, periscope camera modules are widely used. A periscope camera module includes a camera assembly, which in turn includes a drive assembly and a prism. The drive assembly rotates the prism in two directions to adjust the optical path, thus achieving optical image stabilization. However, when adjusting the prism's position, interference often occurs between the two directions, making adjustment difficult and, in severe cases, affecting the quality of the image or video. Summary of the Invention
[0004] The purpose of this application is to provide a camera assembly with relatively high adjustment accuracy. Another purpose of this application is to provide a camera module and electronic device including the above-described camera assembly.
[0005] This application provides a camera component, including: A prism has an input surface and an output surface; The first mounting body, the prism is mounted on the first mounting body; The second mounting body and the first rotating shaft, wherein the first mounting body is rotatably supported on the second mounting body via the first rotating shaft; A base and a first rolling element, wherein at least a portion of the surface of the first rolling element is a first spherical part, and a second mounting body is rotatably supported on the base via the first spherical part; A first driving component is used to drive the first mounting body to rotate relative to the second mounting body around the first rotating shaft; The second driving component is used to drive the second mounting body to rotate relative to the base, and under the action of the first spherical part, the second mounting body can rotate relative to the base around the second direction.
[0006] In this embodiment, a first rotating shaft is connected between a first mounting body and a second mounting body. A first driving component drives the first mounting body to rotate around the first rotating shaft, thereby rotating the prism around a first direction. A first rolling element is disposed between the second mounting body and the base. Under the action of the first rolling element, the second driving component can drive the second mounting body to rotate relative to the base around a second direction, thereby rotating the prism around the second direction. This allows the first mounting body to be driven to rotate around the first rotating shaft, or / and the second mounting body to be driven to rotate relative to the base, based on the direction and angle of vibration of the electronic device, to compensate for the amount of vibration of the electronic device. Because the first rotating shaft and the first rolling element are separately disposed, the adjustment of the prism around the first and second directions does not interfere with each other, improving the adjustment accuracy of the camera assembly and simplifying control.
[0007] In one example, the second mounting body includes a first sidewall and a second sidewall, with the space between the first and second sidewalls used for mounting the first mounting body. A first rotating shaft passes through the first mounting body. The second mounting body also includes a connecting wall, which connects the first and second sidewalls and is located on the side of the first sidewall facing away from the light-receiving surface. The first rotating shaft includes two end segments, which are rotatably supported by the first and second sidewalls, respectively. In this way, the first mounting body is rotatably supported by the two ends of the same first rotating shaft, respectively, with the first sidewall and the second sidewall. By ensuring the machining accuracy of the first rotating shaft, the coaxiality of the rotation between the first and second mounting body's sidewalls can be achieved, which is beneficial for improving the quality of the camera assembly.
[0008] In one example, the system further includes two first bushings, which are respectively fixed to a first sidewall and a second sidewall. Each first bushing has a first mounting hole on its surface facing the first rotating shaft. The wall of the first mounting hole includes two first inclined sections arranged at an included angle. The distance between the two first inclined sections decreases as the distance from the central axis of the first mounting hole increases. The outer wall of the end section of the shaft is supported by the two first inclined sections. The end section of the first rotating shaft is supported by the two first inclined sections, which can help position the first rotating shaft and improve the coaxiality of the first rotating shaft when mounted on the two first bushings.
[0009] In one example, the first bushing includes a bottom surface and two side surfaces. Each side surface is connected to the bottom surface by a second inclined section. The distance between the two second inclined sections decreases as they are further from the central axis of the first mounting hole. One or the second side wall has a receiving groove with an inclined surface that fits snugly against the two second inclined sections. The structure of the first bushing and the receiving groove in a roughly V-shaped configuration allows for precise positioning of the first bushing and further improves the coaxiality of the two first bushings mounted on the second support.
[0010] In one example, a third element and a fourth element are also 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 attract or repel each other magnetically, so that a force parallel to the first direction is applied to the first mounting body. In this way, under the action of the magnetic force of the third and fourth elements, the first mounting body has a predetermined force with the second mounting body in the first direction, which can prevent the first mounting body from shifting along the first direction, and the stability of the camera assembly is higher.
[0011] In one example, the first driving component includes a first magnet assembly and a first electromagnetic coil. The first magnet assembly is located on a first mounting body, and the first electromagnetic coil is mounted on a second mounting body; alternatively, the first magnet assembly is located on a second mounting body, and the first electromagnetic coil is mounted on a first mounting body. In this embodiment, the first electromagnetic coil is mounted on the second mounting body and can rotate with the second mounting body relative to the base around the Z-axis. This ensures that the distance between the first electromagnetic coil and the first magnet assembly does not change due to the rotation of the second mounting body around the Z-axis, further reducing the impact of the second mounting body's rotation around the Z-axis on the first mounting body's rotation around the x-axis.
[0012] In one example, a first magnet assembly and a first electromagnetic coil are arranged along a third direction. A first opening along a third direction is formed between the first and second sidewalls of the second mounting body. The first magnet assembly or the first electromagnetic coil is located at the first opening, where the third direction is perpendicular to the light-emitting surface. The first opening provides space for mounting the first magnet assembly or the first electromagnetic coil, making the camera assembly structure more compact and miniaturized.
[0013] In one example, the first electromagnetic coil is located at the first opening. The camera assembly also includes a flexible circuit board assembly, which comprises 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 located on the side of the first main body opposite to the first electromagnetic coil. The first main body and the first electromagnetic coil are connected to a 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 means of adhesive bonding or other methods. The first support portion can improve the strength of the flexible circuit board assembly and facilitate the fixing of the electromagnetic coil.
[0014] In one example, the flexible circuit board further includes a second main body and a connecting segment. The second main body is connected to the base, and the first main body is connected to the second main body via the connecting segment. The orientation of the connecting segment can change with the rotation of the second mounting body. The connecting segment is a free segment, capable of adapting to changes in the position of the second mounting body to meet the movement requirements of the second mounting body.
[0015] In one example, the base has a second opening opposite to the first opening. The projections of the first main body and the first support in a plane parallel to the light-emitting surface are located inside the projection of the second opening in the same plane. A 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 and the first main body located at the first opening.
[0016] In one example, at least one ferromagnetic material is also included, mounted on the first support portion. The ferromagnetic material and the first electromagnetic coil are located on the same side of the base. The first magnet assembly is also used to cooperate with the ferromagnetic material to generate a force that returns the first mounting body to its initial mounting position. A force can always exist between the first magnet assembly and the ferromagnetic material; for example, the ferromagnetic material can be a steel sheet. Alternatively, the ferromagnetic material can be a coil, and a force is only generated between the first magnet assembly and the ferromagnetic material when the first mounting body needs to return to its initial mounting position. This embodiment of the application utilizes the first magnet assembly in the first driving component, requiring only the installation of the ferromagnetic material on the base to provide an auxiliary positioning force for the first mounting body to remain in its initial position. The first mounting body can maintain a stable state, occupying little space and facilitating installation.
[0017] In one example, the first rolling element is located between the connecting wall and the base, with the connecting wall supported on the base by the first spherical surface of the first rolling element. The second mounting body of this structure is simple in design and relatively lightweight.
[0018] In one example, the first rolling element includes a first ball bearing, a first mounting recess on the connecting wall, and a second mounting recess on the base. The first ball bearing is located in the first mounting recess and rotatably engages with it, while the first ball bearing is located in the second mounting recess and rotatably supported thereon. The ball bearing structure is simple and offers high flexibility in movement.
[0019] In one example, the first mounting recess contacts the first spherical surface line of the first ball located inside it, and / or the second mounting recess contacts the first spherical surface line of the first ball located inside it. The first and second mounting recesses can be configured as approximately V-shaped structures. This provides high mounting stability for the first ball.
[0020] Of course, the cavity wall of the first mounting recess has at least two inclined surfaces, and the third ball abuts against all the inclined surface points in the first receiving cavity; or / and, the cavity wall of the second mounting recess has at least two inclined surfaces, and the third ball abuts against all the inclined surface points in the second receiving cavity; the third ball contacts the cavity wall at two or three points, the contact area is small, the frictional resistance is small when the third ball rotates, and the V-shaped groove or conical groove formed by the inclined surfaces in the cavity wall is conducive to the stable installation of the second ball and improves the rotational stability.
[0021] In one example, the first mounting body has a first cavity on its first surface away from the light-receiving surface, and 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 away from the first protrusion. The first cavity can provide clearance space for the mounting of the first protrusion, which is beneficial to reducing the size of the camera assembly along the first direction. Furthermore, the second pivot is located on the first protrusion, which can improve the strength of the second mounting body connected to the second pivot.
[0022] Alternatively / and, the second surface of the connecting wall opposite to the first mounting body has a second cavity, the base has a second protrusion, the second protrusion is at least partially located in the second cavity, and the second mounting recess is located in the second protrusion. In this embodiment, the second protrusion is provided at the position where the second rotating shaft is located on the base. The second protrusion is relatively thick, which can improve the strength of the position where the second rotating shaft is located. Furthermore, the second cavity is provided on the surface of the second mounting body opposite to the second protrusion. The second cavity can provide installation space for the second protrusion, taking into account both the strength and reliability of use and the small size.
[0023] In one example, both the first and second protrusions are provided with coaxial through holes, and a metal seat is fixed inside each through hole. A first or second mounting recess is disposed within the metal seat. This improves the wear resistance of the first rolling element and the overall strength of the product.
[0024] In one example, at least two second balls are also included, each located circumferentially to the first ball, and the connecting wall is rotatably supported on the base via the second balls. The second balls are located between the first rolling element and the third frame sidewall, providing high support stability and a compact structure.
[0025] In one example, a first spring is included, which connects a first mounting body and a second mounting body. The first spring is used to provide the shape of the restoring force for the first mounting body to return to its initial mounting position. The first spring can deform as the first mounting body rotates. When the first electromagnetic coil is de-energized, the first mounting body can quickly return to its initial mounting position under the restoring force of the first spring.
[0026] Alternatively, / and a first elastic body is installed in a portion of the gap between the first and second mounting bodies. On one hand, the first elastic body maintains the stability of the first mounting body in its initial mounting position; on the other hand, when the first mounting body is driven to rotate, the first elastic body is also compressed or stretched. When the first electromagnetic coil is de-energized, the first mounting body can quickly return to its initial mounting position under the restoring force of the first elastic body. The first elastic body can be a specific elastic component such as rubber or silicone.
[0027] In one example, a second spring is included, which connects both the second mounting body and the base. The second spring is used to provide a restoring force for the second mounting body to return to its initial position, and / or to provide a shape for the second mounting body to abut against the base along a second direction. The second spring can deform as the second mounting body rotates. When the second electromagnetic coil is de-energized, the second mounting body can quickly return to its initial mounting position under the restoring force of the second spring.
[0028] Alternatively and / or including at least one magnetic reset unit, the magnetic reset unit including a first element and a second element, the first element being disposed on the second mounting body, the second element being disposed on the base, the first element and the second element attracting each other to keep and / or return the first mounting body to its initial position; this can further improve the reset speed of the second mounting body and is beneficial to the installation stability of the second mounting body.
[0029] Alternatively / and, a portion of the gap between the second mounting body and the base is fitted with a first elastic body.
[0030] 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 central through hole, and a second elastic body is disposed at the central through hole. The second elastic body protrudes from the side of the first electromagnetic coil facing the first magnet assembly. Thus, when the first mounting body rotates around a 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 contacts the second elastic body first, thereby preventing the first magnet assembly from colliding with the first electromagnetic coil and protecting the first electromagnetic coil.
[0031] Alternatively / and, the second driving component includes a second magnet assembly, a second electromagnetic coil, and a second chip. The second chip is located outside the second electromagnetic coil. The second electromagnetic coil has a central through hole, and a second elastic body is disposed at the central through hole. The second elastic body 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 prevent the second electromagnetic coil from colliding with the second magnet assembly and to protect the second electromagnetic coil.
[0032] In one example, the second driving component includes a second magnet assembly and a second electromagnetic coil, the second magnet assembly being disposed on the first sidewall and / or the second sidewall of the second mounting body, and the second electromagnetic coil being disposed on the base; Alternatively, the second magnet assembly may be disposed on the first sidewall and / or the second sidewall of the second mounting body, or on the base.
[0033] In one example, the device also includes a housing with an inner cavity, in which the prism, the first mounting body, the second mounting body, and the base are mounted. A first elastic body is provided between the first mounting body and the housing to prevent the first mounting body from colliding directly with the housing and to avoid abnormal noise.
[0034] In one example, a magnetic adsorption assembly is also included, comprising a fifth element and a sixth element respectively disposed on the connecting wall and the first mounting body, with the fifth and sixth elements attracting each other in a second direction. This helps to improve the installation stability of the first mounting body.
[0035] In one example, the prism is a triangular prism, which also includes a refractive surface. The light-inlet surface and the light-outlet surface are adjacent, and the refractive surface connects the light-inlet surface and the light-outlet surface. Under the premise of meeting the requirements of light path transformation, the triangular prism has a simple structure, occupies little space, and is lightweight.
[0036] This application also provides a camera component, including: A prism has an input surface and an output surface; The first mounting body, the prism is mounted on the first mounting body; The second mounting body and the second rolling body, wherein at least a portion of the surface of the second rolling body is a second spherical surface, and the first mounting body is rotatably supported on the second mounting body by the second spherical surface; A base and a first rolling element, wherein at least a portion of the surface of the first rolling element is a first spherical part, and a second mounting body is rotatably supported on the base via the first spherical part; 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; The second driving component, under the action of the first spherical surface, drives the second mounting body to rotate relative to the base in a second direction.
[0037] In 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 and second mounting bodies, realizing 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, realizing the rotation of the prism around the second direction. This allows the first mounting body to be driven to rotate around the first direction, or / and the second mounting body to be driven to rotate relative to the base around the second direction, based on the vibration direction and angle of the electronic device, to compensate for the vibration of the electronic device. Because the second rolling body and the first rolling body are disposed between different components, i.e., separately disposed, the prism's rotation adjustment around the first and second directions does not interfere with each other, improving the adjustment accuracy of the camera assembly and simplifying control. Furthermore, the two components are connected by the rolling body, resulting in high mobility. The rolling body occupies a small volume and is relatively lightweight.
[0038] In one example, the first mounting body has a first cavity on its first surface facing away from the light-receiving surface. The first cavity has a third opening and a top wall opposite to the third opening. The second mounting body has a support platform located inside the first cavity, and a second rolling element is located between the top wall and the support platform. The support platform is partially located inside the first cavity, and the structures of the second and first mounting bodies are relatively compact, which is beneficial for miniaturizing the camera assembly.
[0039] In one example, two second rolling elements are arranged between the top wall and the support platform, with the two second rolling elements spaced apart along a first direction, and the support platform and the second rolling elements are arranged opposite each other. The distance between the two second rolling elements along the first direction can be as large as possible, so that the support stability of the first mounting body is relatively high.
[0040] In one example, the second rolling element is a third ball. The top wall and the support platform both have a receiving cavity for rotating with a third ball. The third ball rotates in contact with the receiving cavity. A 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 contact points. This can effectively fix the third ball and effectively avoid the problem of the third ball developing pits.
[0041] Alternatively, the third ball rotates in contact with the cavity wall, and the cavity wall has an annular surface that mates with the third ball. The contact position between the annular surface and the third ball is an annular line. In this embodiment, the cavity is easy to process and form, and the support stability is relatively high with low friction.
[0042] In one example, one of the receiving cavities has a cavity wall with two bevels, the planes of symmetry of which are parallel to a first direction. The other receiving cavities have cavity walls with at least three bevels, and the third ball abuts against all the bevel points in the receiving cavities. In this embodiment, the more bevels there are, the more uniform the force on the third ball.
[0043] In one example, the second mounting body includes a first sidewall, a second sidewall, and a connecting wall. The connecting wall connects the first and second sidewalls and is located on the side of the first sidewall facing away from the light-receiving surface. The space between the first sidewall, the second sidewall, and the connecting wall is used to install the first mounting body. Two support platforms are located on the connecting wall, and a first rolling element is located between the connecting wall and the base. In this embodiment, the second rolling element and the first rolling element are located on both sides of the connecting wall, making full use of 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.
[0044] This application also provides a camera module, including a lens assembly and a camera assembly as described above, wherein the light-emitting surface of the camera assembly faces the light-inlet aperture of the lens assembly.
[0045] This application also provides an electronic device having the aforementioned camera module.
[0046] The camera module and electronic device provided in this application include a camera assembly, and therefore the camera module and electronic device also have the above-mentioned technical effects of the camera assembly. Attached Figure Description

[0049] Current camera components include a prism, a prism support, and a base. The prism is fixed to the prism support, and the prism support and base are in contact via a spherical mating surface. The prism support rotates in different directions around the mating spherical surface to achieve prism rotation around the z-axis or y-axis. The z-axis and y-axis are parallel to the light-incoming and light-outcoming surfaces of the prism, respectively. Since the current prism support (i.e., the device used to support and adjust the prism) rotates around the same spherical surface, this rotation can be either along the z-axis or y-axis. When the prism support rotates in one direction (e.g., the z-axis), it may cause unexpected deflection in another direction (e.g., the y-axis). This phenomenon is called crosstalk, meaning that adjusting the angle in one direction also affects the angle in another direction, resulting in inaccurate directional adjustment. Overcoming these shortcomings is a technical problem that urgently needs to be solved by those skilled in the art.
[0050] This application provides a technical solution that can reduce the probability of crosstalk when the camera component is adjusted in different directions, thereby improving the accuracy of prism position control.
[0051] The embodiments of this application will be further described in detail below with reference to the accompanying drawings and specific examples.
[0052] The camera component in this application embodiment can be applied to various types of electronic devices, including handheld devices, in-vehicle devices, wearable devices, terminal devices, or other processing devices connected to a wireless modem. These devices may also include cellular phones, smartphones, personal digital assistant (PDA) computers, tablets, laptops, camcorders, video recorders, cameras, smartwatches, smart bracelets, augmented reality (AR) devices, virtual reality (VR) devices, in-vehicle computers, and other devices with imaging capabilities. This application embodiment does not impose special limitations on the specific form of the aforementioned electronic devices. For ease of understanding, the following description uses the application of the camera component to a mobile phone as an example. The mobile phone can be a candybar phone or a flip phone.
[0053] Please see Figure 1 , Figure 1 This is a schematic diagram of the structure of an electronic device provided in an embodiment of this application.
[0054] like Figure 1As shown, taking a mobile phone as an example, the electronic device 1000 may include a mid-frame 100, a back cover 200, a decorative panel 210, and a screen 500 (see [link to documentation]). Figure 2 (Structural understanding is shown in the diagram). The middle frame 100 and the back cover 200 are part of the housing 5 of the electronic device 1000; that is, the housing 5 of the electronic device 1000 may include the middle frame 100 and the back cover 200. The screen 500 and the back cover 200 are located on both sides of the middle frame 100, and the middle frame 100 can support and fix the screen 500 and provide protection. The screen 500 is used to display image information or video. When the electronic device 1000 is in use, the user can view the content displayed on the screen 500 or perform input operations on the electronic device 1000.
[0055] Please refer to Figure 2 , Figure 2 for Figure 1 The exploded view of the electronic device shown indicates that screen 500 includes a light-transmitting cover 510 and a display screen 520. The light-transmitting cover 510 and the display screen 520 are stacked and fixedly connected. The light-transmitting cover 510 mainly serves to protect the display screen 520 from dust. The material of the light-transmitting cover 510 includes, but is not limited to, glass and acrylic. The display screen 520 can be a flexible display screen or a rigid display screen.
[0056] The mid-frame 100 may include a mid-plate 110 and a frame portion 120 connected to the periphery of the mid-plate 110. The mid-plate 110 and the frame portion 120 may be integrally formed or connected by welding, bonding, screws, or other methods. The screen 500 and the back cover 200 are located on opposite sides of the mid-plate 110. The material of the back cover 200 includes, but is not limited to, metal, plastic, fiberglass, glass, ceramic, etc. It is understood that in some other embodiments, when the mobile phone is a foldable screen phone, the screen 500 and the back cover 200 may be the first screen and the second screen of the foldable phone, respectively. For example, the screen 500 is the inner screen of the foldable phone, and the back cover 200 is the outer screen of the foldable phone, or the screen 500 is the outer screen of the foldable phone, and the back cover 200 is the inner screen of the foldable phone.
[0057] The rear cover 200 and the middle plate 110 form a mounting cavity, inside which the main circuit board 400, camera module 300, battery, speaker, earpiece, and other electrical components are installed. A sound outlet 101 is provided on the middle frame 100 to facilitate the propagation of sound from the speaker to the outside of the electronic device 1000. For example, an interface 102 can also be provided on the middle frame 100 for electrical connection with external devices via a data cable. The camera module 300 and the main circuit board 400 can be mounted on the middle plate of the middle frame 100 (the position of the middle plate is determined by...). Figure 2(For illustrative purposes only), the main circuit board 400 can be the core circuit board within the electronic device 1000 (a circuit board integrating major components such as a processor, system chip, and power chip). The camera module 300 can be electrically connected to the main circuit board 400. For example, the camera module 300 can be connected to the main circuit board 400 via a flexible printed circuit (FPC) 340. The main circuit board 400 is equipped with a processor, which controls the camera module 300 to capture images. When the user inputs a shooting command, the processor receives the command and controls the camera module 300 to capture images of the target object according to the command.
[0058] 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, with the light-receiving surface of the camera module 300 facing the rear cover 200. The rear cover 200 is provided with a mounting opening 202, and a decorative panel 210 covers and is fixed to the mounting opening 202, serving to protect the camera module 300. The decorative panel 210 is provided with a light-transmitting hole 201, allowing light from the scene to enter the light-receiving surface of the camera module 300. The camera module 300 converts the collected light signals into electrical signals to achieve its shooting function. Glass or highly transparent plastic can also be installed at the light-transmitting hole 201 as a decorative element, which also protects the camera module 300. Figure 2 The image shows an example of an electronic device 1000 with a camera module 300 mounted on its rear side; this camera module 300 is also referred to as a rear-facing camera module. In practical applications, the number of camera modules 300 in the electronic device 1000 is not limited to one; there can be more than one, such as one, two, three, or four. Figure 2 This example illustrates a rear-facing camera module comprising three camera modules. Each camera module 300 is positioned appropriately based on the specific structure of the electronic device 1000.
[0059] When the camera module 300 is used as a front-facing camera, a light-transmitting area can be set on the screen 500. Of course, depending on the location of the camera module 300, a light-transmitting area can also be set in other locations on the mid-frame 100.
[0060] The camera module 300 can be one or more of a standard camera module, a telephoto camera module, a wide-angle camera module, an ultra-telephoto camera module, and an ultra-wide-angle camera module. For example, in one embodiment, the electronic device 1000 also has a front-facing camera module.
[0061] Implementation 1
[0062] Please refer to Figure 3 and Figure 4 , Figure 3 This is a perspective view of the camera module provided in an embodiment of this application, showing only a portion of the structure of the protective shell 30A. Figure 3 The image only schematically illustrates some of the components included in the camera module 300; the actual shape, size, location, and construction of these components are not subject to change. Figure 3 and Figure 4 As well as the limitations of the accompanying figures below.
[0063] For ease of description in the following embodiments, an XYZ coordinate system is established for the camera module 300. Please refer to... Figure 1 and Figure 3 , Figure 4 Understand that the light-receiving axis S of the camera module 300 is the Z-axis direction. The XY plane formed by the X-axis and Y-axis directions is perpendicular to the light-receiving axis S. In some embodiments, after the camera module 300 is assembled into the electronic device 1000, the light-receiving axis S of the camera module 300 can be parallel to the thickness direction of the electronic device 1000 (in conjunction with...). Figure 1 and Figure 4 (Understanding). The plane formed by the width and length directions of electronic device 1000 is parallel to the XY plane.
[0064] Please combine Figure 3 and Figure 4 understand, Figure 4 Examples of embodiments in this application Figure 1 The image shows a cross-sectional view at point M in the electronic device. The camera module 300 in this embodiment is a periscope camera module. A periscope camera module is one that uses a refracting prism to change the direction of light, such as refracting light rays along the thickness direction (Z-axis) of the electronic device 1000 into light rays perpendicular to the thickness direction (z-axis) of the electronic device 1000. This allows the lenses 321 of the lens assembly 320 and the imaging device in the camera module 300 to be arranged inside the electronic device 1000 along a direction perpendicular to the thickness of the electronic device 1000. This not only enables telephoto shooting but also reduces the size of the electronic device 1000 in the thickness direction.
[0065] Please refer to Figure 3As shown, the camera module 300 may include a camera assembly 310, a lens assembly 320, and an image sensor assembly 330, all of which can be integrated inside the same protective housing 30A. Alternatively, the camera assembly 310, lens assembly 320, and image sensor assembly 330 can be separately installed in the electronic device 1000. The camera assembly 310, lens assembly 320, and image sensor assembly 330 can be arranged sequentially along the light path of the camera module; that is, the camera assembly 310 can be located on the light-inlet side of the lens assembly 320, and the image sensor assembly 330 can be located on the light-outlet side of the lens assembly 320. Taking the camera module 300 as a rear camera as an example, the camera assembly 310 can be set to correspond to the light-transmitting hole 201 on the back cover 200. Ambient light enters the camera assembly 310 through the light-transmitting hole 201, and the camera assembly 310 reflects the light to the lens assembly 320. After the light is emitted from the lens assembly 320, it enters the image sensor assembly 330. The image sensor assembly 330 converts the light signal into an electrical signal to realize the imaging function of the camera module 300.
[0066] The direction of the light path from the ambient light entering the camera component 310 is S, and the direction of the light path S is usually the thickness direction of the electronic device. Figure 1 , Figure 3 and Figure 4 (As shown in the Z direction), light is reflected within the camera assembly 310 and enters the lens assembly 320 in the outgoing light path direction S1. The outgoing light path direction S1 is typically the planar direction of the electronic device 1000. Therefore, the optical axis direction of the lens assembly 320 can be set along the planar direction of the electronic device 1000. In other words, the length direction of the lens assembly 320 can be set along the planar direction of the electronic device 1000. For example, the length direction of the lens assembly 320 can be the width direction of the electronic device 1000 (see reference). Figure 1 (x-direction) or length direction (refer to) Figure 1 (in the y direction). The camera module 300 bends the light path through the camera assembly 310, and the lens assembly 320 can be arranged along the plane direction where the electronic device 1000 is located. In this way, while ensuring the optical path length of the camera module 300, the size of the camera module 300 in the thickness direction of the electronic device 1000 can be reduced, which is beneficial to the ultra-thin design of the electronic device 1000.
[0067] Please continue to refer to Figure 4 As shown, the lens assembly 320 may include a lens barrel ( Figure 4 (Not shown in the image) and multiple lenses 321, the lens barrel serving as the basic support structure of the lens assembly 320, the lenses 321 being disposed inside the lens barrel, and the lenses 321 being spaced apart along the axial direction of the lens barrel. Each lens 321 may include a convex lens and a concave lens. Figure 4Although the shapes of each lens 321 are not illustrated, this does not impede the understanding of those skilled in the art regarding the lens assembly 320 described in this application. Each lens 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 lenses 321 can move along the optical axis of the lens assembly 320 to magnify and reduce the target being photographed, thereby achieving the optical zoom function of the camera module 300.
[0068] Of course, please refer to Figure 5 In another embodiment, a front-end lens assembly 330 may also be provided on the light-receiving surface side of the camera assembly 310, and the front-end lens assembly 330 may also include a lens barrel ( Figure 5 (Not shown in the image) and multiple lenses 331, the lenses 331 may include convex lenses and concave lenses, Figure 5 The shapes of each lens 331 are not shown, but this does not impede the understanding of those skilled in the art regarding the front-end lens assembly 330 of this application. The front-end lens assembly 330 can also be an optical zoom lens, or of course, a lens with a fixed focal length.
[0069] Please refer to Figure 4 and Figure 5 In this embodiment, the image sensor assembly 330 may include an image sensor 331 and an image processing chip 332. The image sensor 331 may include a charge-coupled device (CCD) or a complementary metal-oxide-semiconductor (CMOS) phototransistor. The image sensor 331 converts light signals into electrical signals, and then transmits the electrical signals to the image processing chip 332 to obtain an image signal. Light entering the lens assembly 320 passes through each lens 321 and illuminates the photosensitive surface of the image sensor 331. The image sensor 331 converts the light image received on its photosensitive surface into an electrical signal proportional to the light image. This electrical signal is transmitted to the main circuit board 400 via the image processing chip 332 through the FPC.
[0070] 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 image), the driving device is used to drive the lens assembly 320 or image sensor assembly 330 to move. For example, the driving device drives the lens assembly 320 or image sensor 331 to translate along its own plane or rotate angularly around the optical axis of the lens assembly 320, compensating for the displacement caused by the user's hand tremors, preventing blurring of the captured image, improving image clarity, and realizing the optical image stabilization function of the camera module 300. Please refer to... Figure 6 In this embodiment, 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 [link to application]). Figure 7 (As shown). Prism 1, first mounting body 2, second mounting body 3, and base 4 are installed within the inner cavity 53 of housing 5, which protects the components installed inside. To allow light to reach prism 1, housing 5 has clearance openings corresponding to the light-inlet surface 11 and light-outlet surface 12 of prism 1. For example, housing 5 has a light-inlet 51 and a light-outlet 52, respectively opposite to the light-inlet surface 11 and light-outlet surface 12 of the prism. The light-inlet 51 and light-outlet 52 can be respectively located on adjacent sidewalls of housing 5, and can be connected or disconnected. To improve the installation efficiency of housing 5 with other components, positioning posts 46 can also be provided on base 4. The specific structure of housing 5 is not described in detail here.
[0071] Please see Figure 7 , Figure 7 for Figure 6 In the cross-sectional view (AA), in this embodiment, prism 1 is an optical element, having at least an input surface 11, an output surface 12, and a refractive surface 13, capable of reversing the light path. Prism 1 can be one, or two or more. The prism can be a triangular prism, with a right-angled triangle cross-section. Other structural forms are also possible, as long as they meet the light path propagation requirements. Triangular prisms are simple in structure, lightweight, and occupy little space, which is beneficial for meeting the miniaturization design requirements of the 300-cell camera module. This application continues to describe the technical solution using a triangular prism as an example. The input surface 11, output surface 12, and refractive surface 13 of the triangular prism are connected end-to-end. It can be considered that the input surface 11 and output surface 13 are adjacent, and the refractive surface 13 is connected to the input surface 11 and output surface 12. The first mounting body 2 has a support surface 24 for fixing the prism. The refractive surface 13 of prism 1 can be supported on the support surface 24, and the two can be in close contact. Please refer to... Figure 8 It is understood that both end faces 14 of the prism 1 can be bonded and fixed to the first mounting body 2 to improve the reliability of the prism's fixation. For example, adhesive grooves 3C can also be provided on the two side faces 25 of the first mounting body 2, through which liquid adhesive can be injected between the side faces 25 of the first mounting body 2 and the prism 1. The adhesive can be a liquid adhesive or a structural adhesive.
[0072] Combination Figure 4Understand that the light-inlet surface 11 of prism 1 corresponds to the light-transmitting area of electronic device 1000, for example, the light-inlet surface 11 of prism 1 corresponds to the light-transmitting hole 201 of the rear cover 200 of electronic device 1000. The light-exit surface 12 of prism 1 corresponds to the light-inlet side of lens assembly 320. In this way, light from outside electronic device 1000 shines on the light-inlet surface 11 of prism along the S direction, and after reflection inside prism 1, it exits from the light-exit surface 12 of prism 1 along the S1 direction to enter the light-inlet hole of lens assembly 320. Taking prism 1 as a right-angled triangular prism as an example, the S1 direction and the S direction are perpendicular to each other.
[0073] Please refer to Figure 7 and Figure 8 In this embodiment, the first mounting body 2 is rotatably mounted to the second mounting body 3 via a first rotating shaft 9. That is, the first mounting body 2 can rotate relative to the second mounting body 3 around the first rotating shaft 9. The axial direction of the first rotating shaft 9 is along the y-direction. For the sake of brevity in describing the technical solution, this embodiment defines the axial direction of the first rotating shaft 9 as the first direction. Figure 8 The y-direction is indicated in the text. Combined with... Figure 9 Understood, the second mounting element 3 can be roughly a frame structure. Please refer to... Figure 9 and Figure 10 The second mounting body 3 is disposed on the outer periphery of the first mounting body 2, and the first mounting body 2 is located inside the frame of the second mounting body 3.
[0074] In this embodiment, the first rotating shaft 9 can be fixedly connected to the first mounting body 2, and the first rotating shaft 9 can be fixedly connected to the second mounting body 3 by injection molding or interference fit. The first rotating shaft 9 and the second mounting body 3 provide rotatable support. For example, the second mounting body 3 can be provided with mounting holes, and the first rotating shaft 9 is rotatably mounted in the mounting holes.
[0075] Please combine Figure 7 , Figure 8 and Figure 9 Understood, in this embodiment, the camera assembly 310 further includes a first driving component 7, which can drive the first mounting body 2 to rotate relative to the second mounting body 3 around a first direction (y-axis), while the prism 1 rotates with the first mounting body 2 around the first direction. Figure 10 The double-headed dashed arrow in the middle indicates the direction of rotation of the prism reciprocating around the y-axis. That is, the first driving component 7 can drive the first mounting body 2 to rotate in the first plane, which is a plane perpendicular to the first direction (y-axis). In this way, the light-inlet surface 11 and the light-outlet surface 12 of the prism are deflected around the y-axis, and the position and angle of the light-inlet surface 11 and the light-outlet surface 12 of the prism are adjusted along the deflection direction.
[0076] Please see again Figure 8 and Figure 10In this embodiment, the first driving component 7 can be a coil-magnet assembly. The first driving component 7 includes a first electromagnetic coil 71, a first magnet assembly 72, and a first chip 73. The rotation of the first mounting body 2 around a first direction is achieved through closed-loop control by the first chip 73. The first magnet assembly 72 can contain one or more magnets. Figure 8 The diagram shows a first magnet assembly 72 comprising two magnets, namely a first magnet 721 and a second magnet 722. The first magnet 721 and the second magnet 722 have opposite magnetic poles on the side facing the first electromagnetic coil 71, that is, one is the N pole and the other is the S pole.
[0077] Please see Figure 7 , Figure 10 and Figure 11 The first magnet assembly 72 is fixed to the side wall of the first mounting body 2 away from the light-emitting surface 12. In one example, each magnet in the first magnet assembly 72 can be fixed to the first mounting body 2 by adhesive bonding. During installation, the surface of the first magnet assembly 72 and the groove wall of the mounting groove of the first mounting body 2 can be coated with adhesive. In order to improve the fixing reliability of the first magnet assembly 72, an adhesive groove 3C can also be provided on the first mounting body 2. Liquid adhesive is further filled between the first magnet assembly 72 and the second mounting body 2 through the adhesive groove 3C.
[0078] Please combine Figure 10 and Figure 12 It is understood 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 arranged opposite to the first magnet assembly 72. The accompanying drawings illustrate a specific embodiment where the first electromagnetic coil 71 is fixed to the second mounting body 3; the specific technical effects can be found in the following description. The electrical connection wires of the first electromagnetic coil 71 are connected to the external circuit board of the camera assembly 310 via the flexible circuit board assembly 6. When the first electromagnetic coil 71 is energized, a magnetic force of mutual 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 a first direction.
[0079] In this embodiment, the force driving the first mounting body 2 to rotate is provided by the cooperation of the coil and the magnet. The structure is relatively simple, and the current flowing through the coil is controllable, with high adjustment flexibility and high adjustment accuracy.
[0080] To minimize the thickness of the camera assembly 310, the first magnet assembly 72 and the first electromagnetic coil 71 are aligned along a third direction ( Figure 10 Arranged along the x-axis. Please refer to [link / reference]. Figure 13Along a third direction, a first opening 3-41 is formed between the first sidewall 3-1 and the second sidewall 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 sidewall 3-1 and the second sidewall 3-2. In one example, to balance the need for fixing the first electromagnetic coil 71 and the strength of the second mounting body 3, a third sidewall 3-4 is connected between the first sidewall 3-1 and the second sidewall 3-2, and the first opening 3-41 is provided on the third sidewall 3-4. In this way, the distance between the first magnet assembly 72 and the first electromagnetic coil 71 is relatively small, which is beneficial to reducing the size of the camera assembly 310 along a third direction. Furthermore, there is no intermediate obstacle between the first electromagnetic coil 71 and the first magnet assembly 72, so the magnetic field strength generated by the first electromagnetic coil 71 is not weakened, and a large driving force can be provided with a small coil volume, which is beneficial to the miniaturization design of the camera assembly 310.
[0081] In this embodiment, the first electromagnetic coil 71 is mounted on the second mounting body 3 and can rotate relative to the base 4 in the Z direction 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 in the Z direction, further reducing the influence of the rotation of the second mounting body 3 in the Z direction on the rotation of the first mounting body 1 in the x direction.
[0082] In this embodiment, the first mounting body 2 mainly serves to support the prism 1. While satisfying the support function, the weight of the first mounting body 2 can be reduced as much as possible, or the structure of the first mounting body 2 can be simplified to facilitate the installation of other components.
[0083] Please combine Figure 14 and Figure 15 In this embodiment, the first mounting body 2 has a first recess 211 on its first surface 21 facing away from the light-incident surface 11. The second mounting body 3 may further include a connecting wall 3-3, which connects 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 light-incident surface 11 of the prism. The second mounting body 3 is generally a frame structure. The connecting wall 3-3 has a first protrusion 3-32, which is at least partially located inside the first recess 211. The first protrusion 3-32 may be completely or partially located inside the first recess 211. The side of the first protrusion 3-32 facing the first mounting body 2 can be flat, simplifying the manufacturing process. The second rotating shaft 41 is at least partially disposed on the first protrusion 3-32. In this embodiment, the first cavity 211 can provide clearance space for the installation of the first protrusion 3-32, which is beneficial to reduce the size of the camera assembly 310 along the first direction. The first mounting recess 3-321 that accommodates part of the first rolling body 44' is provided in the first protrusion 3-32, which can improve the strength of the mating position between the second mounting body 3 and the first rolling body 44'.
[0084] Please combine Figure 15 , Figure 15 The z-direction shown is the second direction. In this embodiment, the base 4 is located on the side of the second mounting body 3 opposite to the first mounting body 2, the first mounting body 2 is located inside the frame of the second mounting body 3, and the base 4 is located outside the second mounting body 3. The base 4 is also generally a frame structure. The camera assembly 310 also includes a first rolling element 44', and the connecting wall 3-3 is movably supported on the base 4 through the first rolling element 44'. In this embodiment, the structure of the second mounting body 3 is relatively simple, which is beneficial to the lightweight design requirements of the camera assembly 310. Please refer to... Figure 15-1 The first rolling element 44' has at least a spherical surface. For the sake of brevity in describing the technical solution, this application defines the spherical surface of the first rolling element 44' as the first spherical surface 441'. The first rolling element 44' can be a spherical structure, such as a ball bearing, or it can be a hemispherical structure. The second mounting body 3 is supported on the base 4 and is rotatably mounted to the base 4 via the first spherical surface 441' of the first rolling element 44'. To minimize wear and improve 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 can be fixed to the second mounting body 3 or the base 4. The metal seat 3F has a recess that mates with the first rolling element 44'. For example, the metal seat 3F fixed to the second mounting body 3 has a first mounting recess 3-321. Please refer to [link to relevant documentation]. Figure 14 and Figure 15-1 The metal seat 3F, fixed to the base 4, has a second mounting recess 452. The first rolling element 44' is partially located inside the first mounting recess 3-321 and partially inside the second mounting recess 452. The openings of the first mounting recess 3-321 and the second mounting recess 452 are opposite each other and can both be hemispherical, meaning that the entire inner surface of both the first mounting recess 3-321 and the second mounting recess 452 has a surface that rotatably engages with the first rolling element 44'. Alternatively, the inner surfaces of the first mounting recess 3-321 and the second mounting recess 452 can also partially engage with the first rolling element 44'; for example, the first mounting recess 3-321 may be in line contact with the first rolling element 44', and the second mounting recess 452 may also be in line contact with the first rolling element 44'.
[0085] in Figure 15-1 As shown, the inner walls of the first mounting recess 3-321 and the second mounting recess 452 are not perfectly spherical surfaces, and they are in line contact with the first rolling element 44' located inside them. Figure 15-1The positions indicated by the middle arrows are the annular contact positions between the first mounting recess 3-321 and the first rolling element 44', and 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 configured as approximately V-shaped structures. The first mounting recess 3-321 has a downward-opening V-shape, and the second mounting recess 452 has an upward-opening V-shape. This results in higher installation stability and lower friction for the first ball bearing.
[0086] In this embodiment of the application, the first rolling element 44' and the first bushing 32 can both be metal parts, which are high in strength and wear-resistant.
[0087] Please refer to Figure 14 and Figure 15 In this embodiment, the camera assembly 310 further includes a second driving component 8. The second driving component 8 can drive the second mounting body 3 to rotate relative to the base 4, and under the action of the first spherical part 441', the second mounting body 3 can rotate around the second direction (z-axis). That is, the second driving component 8 can drive the entire assembly formed by the second mounting body 3 and the first mounting body 2 to rotate in a second plane, which is a plane perpendicular to the z-axis (second direction). In this way, the light-incoming surface 11 and the light-outgoing surface 12 of the prism can be deflected around the second direction (z-axis), and the position and angle of the light-incoming surface 11 and the light-outgoing surface 12 of the prism can be adjusted along the deflection direction.
[0088] Figure 14 and Figure 15 The image shows that the camera assembly 310 is equipped with two second drive components 8 to maximize the driving force. Specifically, the two second drive components 8 are located on opposite sides of the second mounting body 3 along the first direction. Specifically, the two second drive components 8 are located on opposite sides of the first rotating shaft 9, and they can be installed symmetrically. The second drive components 8 can also be coil-magnet assemblies, combined with... Figure 14 Understanding that a second driving component 8 may include a second electromagnetic coil 81, a second magnet assembly 82, and a second chip 83, the rotation of the second mounting body 3 around a second direction can be achieved through closed-loop control by the second chip 83. The second magnet assembly 82 may contain one or more magnets, combined with... Figure 13 Understanding, in one example, the second magnet assembly 82 includes two third magnets 822 and one fourth magnet 821, where the length of the fourth magnet 821 along the Z-direction is equal to the length of the two third magnets 822 along the Z-direction. The magnetic poles of the third magnets 822 and the fourth magnet 821 on the same side are opposite, for example, from... Figure 13As can be seen, the magnetic pole of the third magnet 822 facing away from the first sidewall 3-1 is the S pole, and the magnetic pole of the fourth magnet 821 facing away from the first sidewall 3-1 is the N pole. Thus, when the second electromagnetic coil 81 is energized, a significant driving force can be generated between the second electromagnetic coil 81 and the second magnet assembly 82. Of course, the number of magnets in the second magnet assembly 82 is not limited to those described in this paper.
[0089] Please refer to all factors. Figure 14 , Figure 15 and Figure 16 It is understood that the camera assembly 310 also includes a magnetic adsorption assembly 37, which includes a fifth element 371 and a sixth element 372. Figure 16 (Not shown in the diagram), 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, providing a force for the first mounting body 2 and the second mounting body 3 to be relatively joined in the second direction, thereby improving system stability. The fifth element 371 and the sixth element 372 can be either a magnet or a metal (e.g., iron) that can be attracted by a magnet. Alternatively, both the fifth element 371 and the sixth element 372 can be magnets.
[0090] Please refer to Figure 16 and Figure 17 It is understood that in this embodiment, a first elastic body 3D may be installed in a portion of the gap between the second mounting body 3 and the base 4. The first elastic body 3D may be an elastic rubber or a component that is prone to elastic deformation, such as foam. In this way, the first elastic body 3D can improve the installation stability of the second mounting body 3 in the base 4 without affecting the rotation of the second mounting body 3 around the second direction. Similarly, a first elastic body 3D may also be installed in a portion of the gap between the first mounting body 2 and the second mounting body 3.
[0091] Please refer to this again. Figure 13 In one example, the second mounting body 3 includes a first sidewall 3-1 and a second sidewall 3-2 spaced apart along a first direction, with a third sidewall 3-4 connecting the first sidewall 3-1 and the second sidewall 3-2. Two second driving components 8 are respectively disposed at the positions of the first sidewall 3-1 and the second sidewall 3-2. Figure 16 As shown, the base 4 includes a first frame sidewall 4-1 and a second frame sidewall 4-2. The first frame sidewall 4-1 is disposed opposite to the first sidewall 3-1 of the second mounting body 3, and the second frame sidewall 4-2 is disposed opposite to the second sidewall 3-2 of the second mounting body 3. A second electromagnetic coil 81 is provided on both the first frame sidewall 4-1 and the second frame sidewall 4-2. The structures for installing the second electromagnetic coil 81 on the two frame sidewalls can be the same or different. Please refer to... Figure 19Understood, this application provides an example of different mounting structures for the first frame sidewall 4-1 and the second frame sidewall 4-2. A third mounting hole 4-22 is provided on both the first frame sidewall 4-1 and the second frame sidewall 4-2, and the second electromagnetic coil 81 is mounted in the third mounting hole 4-22. The third mounting hole 4-22 can be a through hole. A second magnet assembly 82 is provided on both the first sidewall 3-1 and the second sidewall 3-2. In this embodiment, the second electromagnetic coil 81 is mounted on the base 4 for easy connection to the flexible circuit board.
[0092] Of course, in this embodiment, the second electromagnetic coil 81 and the second magnet component 82 can also be respectively disposed on the opposite surfaces of the second mounting body 3 and the base 4, with no other structural obstruction between the second electromagnetic coil 81 and the second magnet component 82, so as to avoid weakening the interaction force between them.
[0093] As described above, in this application, the first rotating shaft 9 is connected between the first mounting body 2 and the second mounting body 3. The first driving component 7 drives the first mounting body 2 to rotate around the first rotating shaft 9, thereby enabling the prism 1 to rotate around the first direction. A first rolling element 44' is provided between the second mounting body 3 and the base 4. Under the action of the first rolling element 44', the second driving component 8 can drive the second mounting body 3 to rotate relative to the base 4 around the second direction, thereby enabling the prism 1 to rotate around the second direction. In this way, 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, according to the vibration direction and vibration angle of the electronic device 1000, to compensate for the vibration of the electronic device 1000. Because the first rotating shaft 9 and the first rolling element 44' are separately provided, the adjustment of the prism 1 around the first and second directions does not interfere with each other, improving the adjustment accuracy of the camera assembly 310 and simplifying the control.
[0094] Please refer to this again. Figure 14 In this embodiment of the application, the connecting wall 3-3 has a second cavity 3-31 on its second surface 3-33 facing away from the first mounting body 2. Combined with... Figure 15 It is understood that the base 4 has a second protrusion 45, which is at least partially located in the second cavity 3-31. The second protrusion 45 is provided with a second mounting recess 452, and the first rolling element 44' is partially located in the second mounting recess 452. In this embodiment, the second protrusion 45 has a relatively large thickness, which can improve the strength of the first rolling element 44'. Furthermore, the second mounting body 3 has a second cavity 3-31 on its surface opposite to the second protrusion 45, which can provide mounting space for the second protrusion 45, thus balancing the aspects of strength, reliability, and small size.
[0095] The shapes of the first protrusion 3-32, the second protrusion 45, the first cavity 211, and the second cavity 3-31 can be reasonably set according to the specific structure, as long as they can meet the above-mentioned functions.
[0096] As described above, in order to improve the wear resistance of the first rolling element 44', in this embodiment of the application, the first rolling element 44' can be matched with a metal seat 3F with 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 protrusion 3-32 or the second protrusion 45 by adhesive or / and welding.
[0097] Please refer to Figure 18 In one specific example, metal bodies are fixed to both the first protrusion 3-32 and the second protrusion 45. These metal bodies can be fixed to the first protrusion 3-32 and the second protrusion 45 via injection molding. In this embodiment, the metal body fixed to the first protrusion 3-32 is defined as the first metal body 33, and the metal body fixed to the second protrusion 45 is defined as the second metal body 43. A metal seat 3F on the first protrusion 3-32 is welded to the first metal body 33, and a metal seat 3F on the second protrusion 45 is welded to the second metal body 43. The first metal body 33 is partially exposed outside the first protrusion 3-32 and has a welding through-hole 3E for welding to the metal seat 3F in the first protrusion 3-32. Similarly, the second metal body 43 can be partially exposed outside the second protrusion 45 and has a welding through-hole 3E for welding to the metal seat 3F in the second protrusion 45. In this configuration, the end of the metal seat 3F in the first protrusion 3-32 that is away from the second protrusion 45 is welded to the first metal body 33. The end of the metal seat 3F in the second protrusion 45 that is away from the first protrusion 3-32 is welded to the second metal body 43.
[0098] Similarly, welding through holes 3E can be provided on both the first metal body 33 and the second metal body 43 to facilitate welding.
[0099] Please refer to this again. Figure 18 In this embodiment of the 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 sidewall 3-1 or the second sidewall 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 with magnetic force so that a force parallel to the first direction is applied to the first mounting body 2. Thus, under the action of the magnetic force of the third element 38 and the fourth element, the first mounting body 2 has a predetermined force with the second mounting body 3 in the first direction, which can prevent the first mounting body 2 from moving along the first direction, and the camera assembly 310 has higher stability. Figure 18The illustration shows an embodiment where the third element is a magnet. In this case, the fourth element can be a metal body, a magnet, or an electromagnet fixed to the first mounting body 2. Of course, the third element can also be metal, in which case the fourth element is a magnet or an electromagnet. The third element can also be an electromagnet or other components, in which case the fourth element can be a magnet, an electromagnet, or a metal.
[0100] Please combine Figure 19 In one example, the base 4 further includes a third frame sidewall 4-3 and a fourth frame sidewall 4-4 connected between the first frame sidewall 4-1 and the second frame sidewall 4-2. The third frame sidewall 4-3 is disposed opposite to the first magnet assembly 72, and a second opening 401 may be provided on the third frame sidewall 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 sidewall 4-4.
[0101] In this embodiment, the first mounting body 2 is rotatably supported by the first rotating shaft 9 and the first side wall 3-1 and the second side wall 3-2 of the second mounting body 3. In order to improve the coaxiality of the first rotating shaft on both sides of the first mounting body 2 with the first side wall 3-1 and the second side wall 3-2, the following structural settings are made to the camera assembly 310.
[0102] like Figure 19-1 As shown, the first mounting body 2 has a through hole 23, and the first rotating shaft 9 passes through the first mounting body 2. The two end segments of the first rotating shaft 9 are located outside the through hole 23. Please refer to... Figure 14 and Figure 15 The camera assembly 310 also includes two first bushings 32. The two ends of the first rotating shaft 9 are supported on the first sidewall 3-1 and the second sidewall 3-2 respectively by the first bushings 32. The inner hole of the first bushing 32 rotates in conjunction with the first rotating shaft 9. This reduces the processing difficulty of the first sidewall 3-1 and the second sidewall 3-2, and allows the first bushing 32 to be made of a different material than the second mounting body 3. For example, the first bushing 32 can be made of a high-strength metal, which improves the wear resistance of the first bushing 32 and the first rotating shaft 9.
[0103] Combination Figure 15 , Figure 20 Understood, in this embodiment, the first mounting hole 322 on the first bushing 32 is a through hole. Each first bushing 32 also has a baffle 34 fixed to the side wall opposite to the first rotating shaft 9 (in conjunction with...). Figure 21(Understanding) 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 baffles 34 can restrict the displacement of the first rotating shaft 9 along the first direction to prevent the first rotating shaft 9 from coming out of 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 improve the coaxiality of the first mounting hole 322 on the first bushing 32 on the first sidewall 3-1 and the second sidewall 3-2, and the processing technology is relatively simple.
[0104] In this embodiment, the first bushing 32 can be made of a wear-resistant material with relatively low hardness. When the electronic device 1000 is accidentally dropped, the first rotating shaft 9 will impact the baffle 34. The baffle 34 should ideally have high hardness to provide high impact resistance, thereby improving the impact resistance of the camera assembly 310. In this embodiment, the baffle 34 is made of a material with a higher hardness than the first bushing 32. For example, the first bushing 32 can be made of copper, and the baffle 34 can be made of stainless steel. Alternatively, the baffle 34 can be made of other metals with a hardness greater than copper.
[0105] The first bushing 32 may also have a recessed portion, and the baffle 34 is installed in the recessed portion to reduce its space occupation. The baffle 34 may also have a welding through hole 3E, and the baffle 34 is welded and fixed to the first bushing 32.
[0106] Please refer to Figure 20 In this embodiment, the first mounting hole 322 can be 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 included angle. The two ends 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 portion is supported by the two first inclined segments 3221. That is, the two first inclined segments 3221 can be roughly V-shaped. Of course, in another embodiment, the two first inclined segments 3221 can be directly connected, that is, there is no need to set the second arc segment 3223.
[0107] In this embodiment, the end section of the first rotating shaft 9 is supported on two first inclined sections 3221. The two first inclined sections 3221 can play the role of 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.
[0108] Similarly, to further improve the coaxiality of the first rotating shaft 9 after installation, this embodiment further sets the first bushing 32 as an irregular structure. The first bushing 32 includes a bottom surface 324 and two side surfaces 325. Each side surface 325 is connected to the bottom surface 324 by a second inclined section 323. The farther away from the central axis of the first mounting hole 322, the smaller the distance between the two second inclined sections 323. The first side wall or the second side wall has a receiving groove 36. The receiving groove 36 has an inclined wall 361 that fits and cooperates with the two second inclined sections 323. Figure 18 Understandably, 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 both inclined walls 361, or simultaneously on the bottom wall 361 of the groove.
[0109] In this embodiment, the structure in which the first bushing 32 and the receiving groove 36 cooperate to support each other is roughly 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 body 3.
[0110] The first bushing 32 can be fixed to the first sidewall 3-1 or the second sidewall 3-2 by adhesive bonding. To improve the reliability of the fixation between the first bushing 32 and the first sidewall 3-1 or the second sidewall 3-2, the first bushing 32 and the first sidewall 3-1 or the second sidewall 3-2 can be further fixed by welding. For example, a metal body 33 is injection-molded inside the first sidewall 3-1 or the second sidewall 3-2, and the first bushing 32 and / or the baffle 34 are welded to the first metal body 33. To facilitate welding, a welding through hole 3E is provided on the first metal body 33. Furthermore, the first metal body 33 is located between the first bushing 32 and the second magnet assembly 82, thus effectively isolating the first bushing 32 and the second magnet assembly 82, preventing collisions and damage to the second magnet assembly 82.
[0111] Please refer to Figure 19 and Figure 22 To minimize friction between the connecting wall 3-3 and the base 4 during relative movement, in this embodiment, the connecting wall 3-3 and the base 4 can also be in rolling contact via a second ball bearing 44. Specifically, at least one second ball bearing 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 by the second ball bearing 44, which is located circumferentially on the second protrusion 45.
[0112] The number of the second ball bearing 44 can be one or more. Figure 19The image shows an example with two second balls 44. The two second balls 44 and one first rolling element 44' are arranged in a triangle, which provides relatively high support stability. The two second balls 44 are located between the first rolling element 44' and the side wall of the third frame, which provides relatively high support stability and a compact structure.
[0113] In one specific example, both the base 4 and the connecting wall 3-3 may also be provided with concave surfaces 3-3A. Figure 22 As shown in the figure, the second ball 44 is located inside the concave surface 3-3A, which limits the range of motion of the second ball 44 and can further improve the installation stability of the second ball 44.
[0114] 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 roll in 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.
[0115] To improve the installation stability of the second mounting body 3 in its initial installation position and to enable it to quickly return to its initial installation position after the second electromagnetic coil 81 is de-energized, the camera assembly 310 may further include a retaining mechanism, partially connected to the second mounting body 3 and partially connected to the base 4, for providing a restoring force for the second mounting body 3 to return to its initial installation position. The initial installation position of the second mounting body 3 refers to its position in the initial assembled state of the camera assembly 310, or its position in the standard state of the camera assembly 310, or its position when the second electromagnetic coil 81 in the camera assembly 310 is de-energized. Several embodiments of the retaining mechanism, including a spring, a magnetic reset unit 35, and an elastic body, are given below.
[0116] Please combine Figure 15 , Figure 18 , Figure 19 and Figure 22 It is understood that the retaining mechanism may further include at least one magnetic reset unit 35, which includes a first element 351 and a second element 352. The first element 351 is disposed on the second mounting body 3, and the second element 352 is disposed on the base 4. The first element 351 and the second element 352 are configured to provide a restoring force for the first mounting body 2 to retain and / or return to its initial position. One of the first element 351 and the second element 352 may be a magnet, and the other may be a metal (e.g., iron) that can be attracted by a magnet. Alternatively, both the first element 351 and the second element 352 may be magnets.
[0117] The first element 351 and the second element 352 attract each other, which can improve the installation stability of the second mounting body 3 to a certain extent. When the second electromagnetic coil 81 is energized, the force generated by the second electromagnetic coil 81 and the second magnet assembly 82 can overcome the attraction between the magnetic reset units 35 and drive the second mounting body 3 to rotate relative to the base 4. When the second electromagnetic coil 81 is de-energized, the attraction between the magnetic reset units 35 can provide a restoring force for the second mounting body 3 to return to its initial position to a certain extent.
[0118] Please refer to Figure 11 and Figure 25 In this embodiment, the camera assembly 310 further includes a first spring 22, which connects to the first mounting body 2 and the second mounting body 3. The first spring 22 is configured to provide a restoring force to the first mounting body 2 to return to its initial mounting position. The initial mounting position of the first mounting body 2 refers to its position in the initial assembled state of the camera assembly 310, or its position in the standard state of the camera assembly 310, or its position when the first electromagnetic coil 71 in the camera assembly 310 is de-energized. Similarly, the initial position of the second mounting body 3 in this embodiment refers to its position in the initial assembled state of the camera assembly 310, or its position in the standard state of the camera assembly 310, or its position when the second electromagnetic coil 81 in the camera assembly 310 is de-energized. The first spring 22 can be a metal sheet with one or more curved structures, which deforms and generates a restoring force under external force. When the first mounting body 2 is in its initial mounting position, the first spring piece 22 can be in its original state, at which time it is not subjected to external force and does not deform. When the first electromagnetic coil 71 is energized, the first mounting body 2 rotates around the first axis, simultaneously causing the first spring piece 22 to move relative to the second mounting body 3, resulting in deformation of the first spring piece 22 and thus generating a restoring force. When the first electromagnetic coil 71 is de-energized, under the restoring force of the first spring piece 22, the first mounting body 2 can quickly return to its initial mounting position. In this embodiment, the spring piece occupies a relatively small space.
[0119] Please refer to this again. Figure 11 On the same side of the first mounting body 2 and the second mounting body 3 ( Figure 11 The diagram shows that both have protruding posts 3A on the side near the light-incoming surface 11 of the prism. The first spring piece 22 has a through hole, which mates with the protruding post 3A to fix the first spring piece 22 to the first mounting body 2, and to the second mounting body 3. This fixing method is relatively simple.
[0120] Please refer to Figure 16 and Figure 25In this embodiment, the retaining mechanism may further include a second spring 42, which connects both the second mounting body 3 and the base 4. The second spring 42 is installed in the same way as the first spring 22, and can be fixed by the cooperation of the protrusion 3A and the through hole. The second spring 42 can provide a restoring force for the second mounting body 3 to return to its initial installation position.
[0121] In addition, by reasonably setting the shape of the second spring 42, the second spring 42 can also provide the second mounting body 3 with a resisting force against the base 4 along the second direction, so that the second mounting body 3 can be stably supported on the base 4.
[0122] Please combine Figure 11 It is understood that in this embodiment of the application, the camera assembly 310 may also include at least one ferromagnetic material 10. Figure 11 The diagram shows a ferromagnetic object 10 mounted on the side of the first electromagnetic coil 71 opposite to the first magnet assembly 72. The ferromagnetic object 10 can be mounted on the support plate 62. Figure 11 (Not shown in the image). 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 an iron-containing material, such as steel, or it can be a magnet. The ferromagnetic body 10 and the first magnet assembly 72 attract each other, which helps the first mounting body 2 to remain and / or return to its initial mounting position.
[0123] The first magnet component 72 attracts the ferromagnetic body 10, which can improve the installation stability of the first mounting body 2 to a certain extent. When the first electromagnetic coil 71 is energized, the force generated by the first electromagnetic coil 71 and the first magnet component 72 can overcome the attraction between the first magnet component 72 and the ferromagnetic body 10, driving the first mounting body 2 to rotate relative to the second mounting body 3. When the first electromagnetic coil 71 is de-energized, the attraction between the first magnet component 72 and the ferromagnetic body 10 can provide a restoring force for the first mounting body 2 to return to its initial installation position to a certain extent.
[0124] This application embodiment utilizes the first magnet component 72 in the first driving component 7, which only requires the installation of the ferromagnet 10 on the base 4, occupying little space and making installation convenient.
[0125] Please refer to Figure 12 and Figure 24 In this embodiment, the camera assembly 310 further includes a flexible circuit board assembly 6, which comprises a flexible circuit board 61 and a support plate 62. The flexible circuit board 61 has a first main body 611, and the support plate 62 includes a first support portion 621. The first main body 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 611. This method provides a simple and convenient fastener.
[0126] In this embodiment, the flexible circuit board further includes a second main body 612 and a connecting segment 613. The second main body 612 is connected to the base 4, and the first main body 611 is connected to the second main body 612 via the connecting segment 613. The orientation of the connecting segment 613 can change with the rotation of the second mounting body 3. The connecting segment 613 is a free segment, capable of adapting to changes in the position of the second mounting body 3.
[0127] In this embodiment, the second main body 612 may further include multiple sections, such as sections fixed to the first frame sidewall 4-1, the second frame sidewall 4-2, and the fourth frame sidewall 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 of the flexible circuit board 61, which is electrically connected to the external circuit, is located outside the housing 5. Please refer to [reference needed]. Figure 6 .
[0128] In this embodiment, the support plate 62 can be a separate unit. For example, support plates 62 can be provided on one or more sides of the base 4 away from the second mounting body 3 to support and position the flexible circuit board. The support plate 62 plays a role in protecting the flexible circuit board to a certain extent. Furthermore, the support plate 62 located on the fourth frame sidewall 4-4 of the base 4 can directly close the opening on that side of the housing 5, becoming part of the housing 5 (see reference). Figure 7 To minimize the weight of the camera assembly 310.
[0129] Example 2
[0130] Please see Figure 26 This application also provides another embodiment of the camera assembly 310. From an appearance perspective, this embodiment is substantially the same as the camera assembly 310 in Embodiment 1. The structure of the camera assembly 310 disclosed in this application is similar to... Figures 6-25 The disclosed camera component 310 performs largely the same functions. Please refer to [link / reference]. Figure 27 In this embodiment, 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 component 7, a second driving component 8, and an FPC. The main structures of the above components are basically the same as those described above. Figures 6-25 The structures described in the text are largely the same, especially the structures of the shell, prism 1, first rolling element, and FPC. Figures 6-25 There is essentially no difference; please refer to the relevant content in Example 1, which will not be described in detail here.
[0131] In terms of structure, the biggest difference between the embodiments of this application and Embodiment 1 is that: Figures 26 to 42In the camera assembly 310, the first mounting body 2 is supported on the second mounting body 3 by the second rolling body 26.
[0132] The following section describes the differences in detail, and... Figures 6-25 The structural similarities will be briefly described below; for details, please refer to the text above. Figures 6-25 The description of the corresponding structure in the text.
[0133] In the embodiments of this application, Figure 28 A specific embodiment where the second rolling element 26 is a ball bearing is shown. For ease of description, this application defines the ball bearing of the second rolling element 26 as a third ball bearing. The ball bearing 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 to the second mounting body 3 via the third ball bearing, so that it can rotate relative to the second mounting body 3 about a first direction. Please refer to... Figure 30 A schematic diagram of the assembly of the first mounting body 2 and the second mounting body 3.
[0134] The second rolling element 26 can be in the form of a ball bearing or other forms, such as a hemispherical structure. That is, at least part of the surface of the second rolling element 26 is a spherical surface. For the sake of brevity in describing the technical solution, this application defines the spherical surface of the second rolling element 26 as the second spherical surface. The first mounting body 2 is rotatably supported on the second mounting body 3 through the second spherical surface, and the first mounting body 2 is rotatably mounted to the second mounting body 3 through the second spherical surface so that it can rotate relative to the second mounting body 3 about a first direction.
[0135] Please combine Figure 28 The first mounting body 2 has a first surface 21 facing away from the light-receiving surface. The first surface 21 has a first cavity 211, and the first cavity 211 has a third opening facing the second mounting body 3. The first cavity 211 also includes a top wall 212 opposite to the third opening. Please refer to [reference needed]. Figure 29The second mounting body 3 includes a first sidewall 3-1, a second sidewall 3-2, and a connecting wall 3-3. A support platform 3-34 is provided on the connecting wall 3-3, and the support platform 3-34 is at least partially located inside the first cavity 211. The third ball (second rolling element 26) is located between the top wall 212 and the support platform 3-34. The support platform 3-34 is partially located inside the first cavity 211. The second mounting body 3 and the first mounting body 2 have a relatively compact structure, which is beneficial for the miniaturization of the camera assembly 310. There can be two third balls, arranged at intervals along a first direction. The support platform 3-34 on the second mounting body 3 corresponds one-to-one with the third ball, meaning that the second mounting body 3 also has two support platforms 3-34, located at opposite ends of the connecting wall 3-3 along the first direction. This results in a relatively large distance between the two support platforms 3-34 along the first direction, allowing the distance between the two third balls to be as far as possible, thus providing high stability for the first mounting body 2.
[0136] Please refer to all factors. Figure 28 and Figure 29 In this embodiment, the top wall 212 has a cavity 3-35 for the rotational engagement of the third ball, and the support platform 3-34 also has a cavity 3-35 for the rotational engagement of the third ball. The two cavities 3-35 corresponding to the top wall 212 and the support platform 3-34 enclose a space for accommodating the third ball. The third ball and the cavity wall of the cavity 3-35 on the support platform 3-34, and the third ball and the cavity wall of the cavity 3-35 on the top wall 212 can be in surface contact, that is, the cavity wall of the cavity 3-35 on the support platform 3-34 can be part of a sphere, and the cavity wall of the cavity 3-35 on the top wall 212 can also be part of a sphere. Of course, the third ball bearing and the cavity wall of the receiving cavity 3-35 on the support platform 3-34, and the third ball bearing and the cavity wall of the receiving cavity 3-35 on the top wall 212 can also be in line contact. The specific structure of the receiving cavity 3-35 can refer to the structure of the first mounting recess 3-321 and the second mounting recess 452 in Embodiment 1. This structure is beneficial for the coaxial installation of the third ball bearing and the receiving cavity 3-35 on the support platform 3-34 and the receiving cavity 3-35 on the top wall 212.
[0137] Furthermore, the cavity wall of the receiving cavity 3-35 on the support platform 3-34 and the third ball bearing, as well as the cavity wall of the receiving cavity 3-35 on the top wall 212 and the third ball bearing, can also have multiple points of contact. This application embodiment shows two structures for the receiving cavity 3-35: the first structure is as follows: Please refer to... Figure 30The receiving cavity 3-35 has a cavity wall with three inclined surfaces 4A forming a conical structure. The closer to the opening of the receiving cavity 3-35, the larger the size of the conical structure. The three inclined surfaces 4A can be arranged at equal angles along the circumference, and the inclination angle and size of each inclined surface 4A are basically the same. The third ball abuts against all the inclined surfaces 4A in the receiving cavity 3-35. The second structure is as follows: Please refer to... Figure 31 The cavity 3-35 has a cavity wall with two inclined surfaces 4A facing each other. The plane of symmetry of the two inclined surfaces is parallel to the first direction. The two inclined surfaces form a V-shaped groove. The farther away from the opening of the 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 cavity 3-35 can be connected, or they can be connected through the middle section.
[0138] In this embodiment, the cavity wall of the receiving cavity 3-35 abuts against the third ball at two or more points, which can effectively fix the third ball and effectively avoid the problem of pitting the third ball.
[0139] Please refer to this again. Figure 28 , Figure 29 Understandably, in this embodiment of the application, except for one receiving cavity 3-35 on the support platform 3-34 which is configured as the second structural form, the other three receiving cavities 3-35 are configured as the first structure. In this way, the receiving cavity 3-35 of the first structure can constrain the relative position of the first mounting body 2 and the second mounting body 3 in the second direction and in the plane perpendicular to the second direction, that is, the number of constrained degrees of freedom is relatively large, which can improve the accurate positioning of the relative position of the first mounting body 2 and the second mounting body 3. On the other hand, the receiving cavity 3-35 of the second structure has fewer constrained degrees of freedom, avoiding over-positioning of the first mounting body 2 and the second mounting body 3.
[0140] Those skilled in the art should understand that the structure of the receiving cavity 3-35 on the support platform 3-34 and the structure of the receiving cavity 3-35 on the top wall 212 may be the same or different. The structure of the receiving cavity 3-35 may be any of the spherical surface, the line contact annular surface, or the multi-point contact inclined surface mentioned above.
[0141] To improve the structural strength of the accommodating cavities 3-35, in this embodiment, the first mounting body 2 and the second mounting body 3 may have metal inserts 28 inside, combined with... Figure 30 and Figure 31 It is understood that the metal insert 28 can be pre-machined with accommodating cavities 3-35. The metal insert 28 is integrated with the first mounting body 2 or the second mounting body 3 through injection molding. In this embodiment, the overall structure of the camera assembly 310 is also relatively high, improving the quality of the camera assembly 310.
[0142] The specific shape of a metal insert can be determined according to its location. This application illustrates two specific structures of metal inserts; please refer to them. Figure 30 The first type of metal insert has a receiving cavity 3-35 with three bevels 4A, forming a conical receiving cavity 3-35 structure. Please refer to [reference needed]. Figure 31 The second type of metal insert has a receiving cavity 3-35 with two inclined surfaces 4A, forming a V-groove structure. Of course, the structure of the metal insert is not limited to the structure shown in this paper, and can also be other shapes.
[0143] Please refer to Figure 32 , Figure 33 and Figure 34 Understood, in this embodiment of the 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 provides relatively high support stability for the first mounting body 2, and the structure of the first mounting body 2 and the second mounting body 3 in the camera assembly 310 is more compact, which can minimize the space occupied by the camera assembly 310, especially reduce the size of the camera assembly 310 along the second direction.
[0144] Please refer to Figure 36 , Figure 36 for Figure 35 The diagram shows a cross-sectional view of the structure along the E1-E1 direction. In this embodiment, the driving force of the first mounting body 2 relative to the second mounting body 3 in the first direction also originates from the first driving component 7. The first driving component 7 includes a first electromagnetic coil 71, a first magnet assembly 72, and a first chip 73. Figures 6-25 Unlike the disclosed structures, in this embodiment, the first chip 73 is located outside the first electromagnetic coil 71, and a second elastic body 3M is installed at the central through-hole of the first electromagnetic coil 71. A portion of the second elastic body 3M protrudes from the side of the first electromagnetic coil 71 facing the first magnet assembly 72. Figure 37 Understand. Figure 36 Taking the example of a first electromagnetic coil 71 mounted on a second mounting body 3 and a first magnet assembly 72 mounted on a first mounting body 2, when the first mounting body 2 rotates around a first direction, the distance between the first mounting body 2 and the second mounting body 3 changes. Because the second elastic body 3M protrudes from the first electromagnetic coil 71, the first magnet assembly 72 contacts the second elastic body 3M first, thereby reducing the probability of a collision between the first magnet assembly 72 and the first electromagnetic coil 71, thus 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 central through-hole position of the first electromagnetic coil 71, can also reduce the probability of a collision between the first magnet assembly 72 and the first electromagnetic coil 71.
[0145] Mounting 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.
[0146] Of course, the first chip 73 in this embodiment can also be set at the central through hole of the first electromagnetic coil 71, in the same way as in embodiment 1.
[0147] In this embodiment of the application, the power for the second mounting body 3 to rotate relative to the base 4 in a 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. Figure 38 It is understood that there are two second drive components 8, which are located on one side of the first sidewall 3-1 and the second sidewall 3-2 of the second mounting body 3, respectively.
[0148] The structure of the second magnet component 82 can be referred to the relevant description in Embodiment 1, Appendix Figure 39 An example of a second magnet assembly 82 including a third magnet and a fourth magnet is shown. Those skilled in the art will understand that the structure of the second magnet assembly 82 and the second electromagnetic coil 81 is not limited to the structure described herein, as long as it can drive the second mounting body 3 to rotate relative to the base 4 about a second direction.
[0149] Please refer to this again. Figure 37 ,and Figures 6-25 Unlike the disclosed structure, in this embodiment, the second chip 83 is also located outside the central through-hole of the second electromagnetic coil 81. Please refer to [reference needed]. Figure 37 (The second electromagnetic coil 81 and the second magnet assembly 82 at the position of the first sidewall 3-1 are not shown.) The second electromagnetic coil 81 has a second elastic body 3M installed in the central through hole to reduce the probability of the second electromagnetic coil 81 being hit by the second magnet assembly 82.
[0150] Second magnet assembly 82, second mounting body 3, base 4, second magnet assembly 82, second electromagnetic coil 81, combined. Figure 28 , Figure 29 and Figure 38 It is understood that in this embodiment of the application, the first spring clip may not be provided between the first mounting body 2 and the second mounting body 3 (see [link]). Figure 11The first spring 22 simplifies the structure and assembly process of the camera assembly 310 and reduces product costs. The force that holds or returns the first mounting body 2 to its initial position can be provided solely by magnetic components, such as the magnetic adsorption component 37 described in Embodiment 1, as well as third and fourth elements (the third and fourth elements are not shown in the figures of Embodiment 2, but can be referred to the description in Embodiment 1). The shape and number of magnetic components are not limited.
[0151] Under the premise of achieving the above-mentioned functions of the camera assembly 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 they can be slightly different from Embodiment 1. For example, please refer to... Figure 39 In this embodiment, the outer walls of the two side walls of the first mounting body 2, which are spaced apart along the first direction, also have protrusions 27. The protrusions 27 extend to the top of the first side wall 3-1 or the second side wall 3-2 of the second mounting body 3, thus limiting 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. This allows the rotation angle of the first mounting body 2 to be limited without hindering its rotation around the first axis, and the overall structure is relatively compact and small in size.
[0152] Similar to Embodiment 1, in this embodiment, the second mounting body 3 is connected to the base 4 via ball bearings and can rotate relative to the base 4 about a second direction. The metal seat 3F on the second mounting body 3 and the base 4 that mates with the ball bearings can be the same as the metal seat structure in Embodiment 1, or it can be different. Figures 40 to 42 Another embodiment of the metal seat 3F is given, in which three inclined surfaces 4A are also provided, and the ball bearings make contact with the metal seat 3F at three points. This facilitates the coaxial positioning and installation of the second mounting body 3 and the base 4, and provides better fixation for the ball bearings. Of course, the metal seat 3F in this embodiment can also be provided with a spherical surface that contacts and mates with the ball bearing surface.
[0153] In this application, under the driving force of the first driving component 7, the first mounting body 2 can rotate around the second rolling element 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 element 44' connected between the second mounting body 3 and the base 4, so that the prism rotates around the second direction. In this way, the first mounting body 2 can be driven to rotate around the first direction, or / and the second mounting body 3 can be driven to rotate relative to the base 4 around the second direction, according to the vibration direction and vibration angle of the electronic device, so as to compensate for the vibration of the electronic device. Since the second rolling element 26 and the first rolling element 44' are set between different components, that is, the two are set separately, the 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 the rolling element, which has high mobility. The rolling element occupies a small volume and is relatively light in weight.
[0154] Please refer to Figure 43 In this embodiment of the application, the second spring clip may not be provided between the second mounting body 3 and the base 4 (see [link]). Figure 16 The second spring 42 further simplifies the structure and assembly process of the camera assembly. The second mounting body 3 retains and / or returns to its initial position; the restoring force can be provided by the magnetic reset unit 35. For the location and structure of the magnetic reset unit 35, please refer to [reference needed]. Figure 38 The specific structure of the magnetic reset unit 35 can be referred to in Embodiment 1.
