Description

Technical Field

[0001] This disclosure relates to the field of electronic device technology, specifically to a camera module and an electronic device. Background Technology

[0002] With the development of electronic devices, their camera performance has continuously improved. This has led to larger chip sizes and increased thickness in camera modules, resulting in increasingly larger protruding decorative parts. These protruding parts significantly impact the aesthetics of electronic devices and the user's grip. Therefore, reducing the protrusion height of decorative parts in camera modules has become an urgent problem to be solved.

[0003] In related technologies, the decorative component of the camera module is designed as a movable decorative component that can be raised and lowered, and a drive mechanism is provided to drive the movable decorative component to rise and fall. When the camera module is in the working state, the drive mechanism drives the movable decorative component to rise, increasing the overall thickness of the camera module; when the camera module is not in the working state, the drive mechanism drives the movable decorative component to fall, shortening the overall thickness of the camera module, thereby improving the aesthetics of the electronic device and the user's grip. However, the movable decorative component, the drive mechanism, and the camera assembly of the camera module are coupled together, which means that when the structure or size of the camera assembly is different, the movable decorative component and the drive mechanism need to be redesigned, resulting in higher design and manufacturing costs for different models of camera modules.

[0055] Embodiments of this disclosure are described in detail below, with examples of embodiments illustrated in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this disclosure, and should not be construed as limiting this disclosure.

[0056] like Figures 1 to 4 As shown, the camera module 100 of this embodiment includes a camera assembly and a decorative assembly. The camera assembly includes a camera bracket 1 and a lens assembly 2. The camera bracket 1 has a cavity 11, and at least a portion of the lens assembly 2 is disposed within the cavity 11 and connected to the camera bracket 1. The decorative assembly is disposed outside the cavity 11 and connected to the camera bracket 1. The decorative assembly includes a movable decorative element 4 and a driving mechanism 5. The movable decorative element 4 is sleeved on the outside of the camera assembly, and the driving mechanism 5 is throttle-connected to the movable decorative element 4 to drive the movable decorative element 4 to move along the optical axis direction of the camera module 100.

[0057] The camera module 100 of this embodiment includes a camera assembly comprising a camera bracket 1 and a lens assembly 2, with at least a portion of the lens assembly 2 disposed within and connected to the camera bracket 1 cavity 11. A decorative assembly is disposed outside and connected to the camera bracket 1 cavity 11, and a movable decorative element 4 of the decorative assembly is fitted onto the outside of the camera assembly. Both the decorative assembly and the lens assembly 2 use the camera bracket 1 as their mounting base. As long as both the decorative assembly and the lens assembly 2 are connected to the camera bracket 1, the decorative assembly can be used for lens assemblies 2 of different structures or sizes, achieving decoupling between the decorative assembly and the lens assembly 2. Therefore, even when the structure or size of the lens assembly 2 differs, the same set of decorative components can still be used, thereby reducing the design and manufacturing costs of different models of camera modules 100.

[0058] Furthermore, by driving the drive mechanism 5 to the movable decorative element 4, the overall thickness of the camera module 100 can be adjusted by driving the movable decorative element 4 to move along the optical axis of the camera module 100. For example, when the camera module 100 is in the working state, the movable decorative element 4 moves in the direction away from the lens assembly 2 to increase the overall thickness of the camera module 100; when the camera module 100 is not in the working state, the movable decorative element 4 moves in the direction towards the lens assembly 2 to shorten the overall thickness of the camera module 100.

[0059] In some embodiments, such as Figures 1 to 4 As shown, the decorative component also includes a fixed decorative element 6, which is sleeved on the outside of the movable decorative element 4. The movable decorative element 4 is movably connected to the fixed decorative element 6 along the optical axis of the camera module 100.

[0060] It is understandable that when installing the camera module 100 on an electronic device, the decorative component needs to be sealed to the housing of the electronic device. If the movable decorative part 4 is directly sealed to the housing of the electronic device, then there will be a dynamic seal between the movable decorative part 4 and the housing of the electronic device, making it difficult to install the camera module 100 on the electronic device.

[0061] By configuring the decorative component to include a fixed decorative element 6, and fitting the fixed decorative element 6 onto the outside of the movable decorative element 4, when the camera module 100 is installed on the electronic device, the fixed decorative element 6 can be used to seal the connection between the decorative component and the housing of the electronic device, thus achieving a seal between the decorative component and the housing of the electronic device. Since the fixed decorative element 6 is relatively fixed to the housing of the electronic device, a static seal is achieved between the decorative component and the housing of the electronic device, facilitating the installation of the camera module 100 on the electronic device.

[0062] Optionally, such as Figures 2 to 4As shown, the decorative component also includes a guide 7, which is connected to the fixed decorative component 6. The guide 7 is provided with a first guide portion 71, and the movable decorative component 4 is provided with a second guide portion 411. The second guide portion 411 is movable along the optical axis direction of the camera module 100 and is guided and cooperated with the first guide portion 71.

[0063] By providing a guide member 7 connected to the fixed decorative member 6, and a second guide member 411 that cooperates with the first guide member 71 of the guide member 7 on the movable decorative member 4, when the movable decorative member 4 moves relative to the fixed decorative member 6 along the optical axis direction of the camera module 100, the second guide member 411 and the first guide member 71 can be used to guide the movement direction of the movable decorative member 4, preventing the movement direction of the movable decorative member 4 from deviating. This improves the reliability of the movable decorative member 4, and consequently improves the reliability of the camera module 100.

[0064] Optionally, there are multiple guide members 7, which are arranged at intervals along the circumference of the fixed decorative member 6. There are multiple second guide parts 411, which correspond one-to-one with the guide members 7, and the second guide parts 411 are guided and cooperated with the first guide part 71 of the corresponding guide member 7.

[0065] By setting the number of guide members 7 and the number of second guide parts 411 to multiple, and arranging the multiple guide members 7 at intervals along the circumference of the fixed decorative member 6, the second guide part 411 can be guided and cooperated with the first guide part 71, which can also prevent the movable decorative member 4 from rotating relative to the fixed decorative member 6.

[0066] Optionally, such as Figures 2 to 4 As shown, the fixed decorative component 6 includes a fixed bracket 61 and a fixed decorative component body 62. The fixed decorative component body 62 has a fixed appearance surface 624, and the fixed bracket 61 is located on the side of the fixed decorative component body 62 facing away from the fixed appearance surface 624. The guide component 7 is connected to the fixed bracket 61, and the fixed decorative component body 62 is connected to the fixed bracket 61.

[0067] For example, such as Figure 5 and Figure 6 As shown, the fixed bracket 61 has a mounting hole 612, and a part of the guide member 7 is inserted into the mounting hole 612 and connected to the hole wall of the mounting hole 612. The guide member 7 and the hole wall of the mounting hole 612 can be interference-fitted, bonded or welded.

[0068] By configuring the fixed decorative component 6 as including a fixed bracket 61 and a fixed decorative component body 62, with the fixed bracket 61 located on the side of the fixed decorative component body 62 facing away from the fixed appearance surface 624, and the guide component 7 connected to the fixed bracket 61, it is possible to avoid setting a connection structure for connecting to the guide component 7 on the fixed decorative component body 62, thus facilitating the processing and manufacturing of the fixed decorative component 6. This helps to reduce the manufacturing cost of the camera module 100.

[0069] Optionally, such as Figures 2 to 4 As shown, the guide member 7 is a guide rod, and the outer peripheral surface of the guide rod forms a first guide portion 71. The second guide portion 411 is a guide hole, and the guide rod is inserted into the guide hole. The guide rod and the guide hole can be clearance-fitted.

[0070] By designing the guide member 7 as a guide rod and the second guide part 411 as a guide hole, the structure of the guide member 7 and the movable decorative member 4 is simplified, facilitating the processing and manufacturing of the decorative components. This helps to reduce the manufacturing cost of the camera module 100.

[0071] Optionally, such as Figure 3 , Figure 5 and Figure 7 As shown, the fixed bracket 61 is provided with a mounting groove 611, and the fixed decorative body 62 is provided with a mounting part 622. The mounting part 622 is inserted into the mounting groove 611 and connected to the groove wall of the mounting groove 611.

[0072] For example, the fixing bracket 61 has a mounting groove 611 with the opening facing the fixing decorative body 62, and the mounting groove 611 is annular. The mounting part 622 of the fixing decorative body 62 is sleeve-shaped, and the mounting part 622 is bonded or welded to the groove wall of the mounting groove 611.

[0073] By providing a mounting groove 611 in the fixed bracket 61 and a mounting part 622 in the fixed decorative component body 62, when connecting the fixed decorative component body 62 to the fixed bracket 61, the mounting part 622 can be inserted into the mounting groove 611 first to achieve pre-positioning between the fixed decorative component body 62 and the fixed bracket 61, and then the fixed decorative component body 62 and the fixed bracket 61 can be connected. This improves the assembly efficiency of the fixed decorative component body 62 and the fixed bracket 61, and thus improves the assembly efficiency of the camera module 100.

[0074] Optionally, such as Figure 3 , Figure 7 , Figure 8 and Figure 10As shown, the fixed decorative component 6 has an annular fixed sealing portion 621, and the movable decorative component 4 has an annular movable sealing portion 421. The fixed sealing portion 621 is sleeved on the outside of the movable sealing portion 421. The decorative assembly also includes an annular first sealing element 81, which is disposed between the fixed sealing portion 621 and the movable sealing portion 421 and is in a sealing fit with both the fixed sealing portion 621 and the movable sealing portion 421.

[0075] For example, such as Figure 7 As shown, the fixed sealing part 621 is provided with an annular first sealing surface 6211, such as Figure 10 As shown, the movable sealing part 421 is provided with an annular second sealing surface 4211. For example... Figure 3 and 8 As shown, the first sealing member 81 includes an annular first connecting edge 811, an annular second connecting edge 812, and a cylindrical first deformable portion 813. The first connecting edge 811 and the second connecting edge 812 are respectively located at opposite ends of the first deformable portion 813. The first connecting edge 811 is located radially outward of the first deformable portion 813, and the second connecting edge 812 is located radially inward of the first deformable portion 813. The surface of the first connecting edge 811 facing away from the second connecting edge 812 is sealed to the first sealing surface 4211, and the surface of the second connecting edge 812 facing the first connecting edge 811 is sealed to the second sealing surface 4211. When the movable decorative member 4 moves relative to the fixed decorative member 6 along the optical axis of the camera module 100, the first deformable portion 813 undergoes elastic deformation along the optical axis of the camera module 100.

[0076] Of course, the first seal 81 can also be configured in other forms. For example, one of the fixed seal portion 621 and the movable seal portion 421 can be sealed and connected to the first seal 81, while the other of the fixed seal portion 621 and the movable seal portion 421 can be movably sealed and fitted with the first seal 81 along the optical axis of the camera module 100. In this case, there is a static seal between one of the fixed seal portion 621 and the movable seal portion 421 and the first seal 81, and a dynamic seal between the other of the fixed seal portion 621 and the movable seal portion 421 and the first seal 81.

[0077] By providing a first sealing element 81 between the fixed sealing part 621 and the movable sealing part 421, a seal can be achieved between the movable decorative part 4 and the fixed decorative part 6, preventing dust, moisture, etc. from entering the interior of the camera module 100 from between the movable decorative part 4 and the fixed decorative part 6, thereby improving the reliability of the camera module 100.

[0078] In some embodiments, such as Figures 2 to 4As shown, the movable decorative component 4 includes a movable bracket 41 and a movable decorative component body 42. The movable decorative component body 42 has a movable outer surface 425, and the movable bracket 41 is located on the side of the movable decorative component body 42 facing away from the outer surface. The drive mechanism 5 is connected to the movable bracket 41, and the movable decorative component body 42 is connected to the movable bracket 41.

[0079] By designing the movable decorative element 4 as including a movable bracket 41 and a movable decorative element body 42, with the movable bracket 41 located on the side of the movable decorative element body 42 facing away from the exterior surface, and the drive mechanism 5 being connected to the movable bracket 41, it is possible to avoid setting a connection structure for the drive mechanism 5 on the movable decorative element body 42, thus facilitating the processing and manufacturing of the movable decorative element 4. This helps to reduce the manufacturing cost of the camera module 100.

[0080] Optionally, such as Figures 2 to 4 As shown, the decorative assembly also includes a connector 91 and a buffer 92. The movable decorative body 42 is connected to the connector 91, and the movable bracket 41 is movably connected to the connector 91 in a direction opposite to the movable appearance surface 425. The buffer 92 is disposed between the movable bracket 41 and the movable decorative body 42 to provide a spring force to the movable decorative body 42 toward the movable appearance surface 425.

[0081] For example, such as Figures 9 to 10 As shown, the movable bracket 41 is provided with a first connecting part 412, the movable decorative body 42 is provided with a second connecting part 422, the second connecting part 422 is connected to the connector 91, and the first connecting part 412 is movably connected to the connector 91 along the optical axis direction of the camera module 100.

[0082] To make the technical solution of this disclosure easier to understand, the following description further illustrates the technical solution of this disclosure, taking the example that the optical axis direction of the camera module 100 is consistent with the vertical direction. Wherein, the vertical direction is as follows... Figures 1 to 16 As shown.

[0083] For example, the upper surface of the movable decorative part body 42 is the movable exterior surface 425. The movable decorative part body 42 is connected to the connector 91, and the movable bracket 41 is movably connected to the connector 91 in the vertical direction. The buffer 92 provides an upward elastic force to the movable decorative part body 42. When the drive mechanism 5 drives the movable bracket 41 to move upward, the buffer 92 pushes the movable decorative part body 42 to move upward; when the drive mechanism 5 drives the movable bracket 41 to move downward, the connector 91 drives the movable decorative part body 42 to move downward; when the movable decorative part body 42 receives downward pressure from the outside, the movable decorative part body 42, together with the connector 91, moves downward relative to the movable bracket 41 to prevent the movable decorative part body 42 from being damaged by external force.

[0084] By setting the connector 91 and the buffer 92, while enabling the movable decorative body 42 to move toward the movable bracket 41 toward the movable outer surface 425, it is also possible to prevent the movable decorative body 42 from being damaged by external forces, which is beneficial to extending the service life of the camera module 100.

[0085] Optionally, such as Figure 2 , Figure 3 and Figure 13 As shown, the buffer 92 is a spring, and the buffer 92 is sleeved on the guide 7.

[0086] By disabling the buffer 92, the elasticity of the buffer 92 in the optical axis direction of the camera module 100 is improved. In addition, the buffer 92 is fitted onto the guide 7, which facilitates the installation and fixation of the buffer 92.

[0087] Optionally, such as Figure 9 and Figure 10 As shown, the movable bracket 41 is provided with a first anti-rotation part 415, and the movable decorative body 42 is provided with a second anti-rotation part 424, which cooperates with the first anti-rotation part 415.

[0088] For example, the first anti-rotation part 415 is an anti-rotation groove, and the second anti-rotation part 424 is an anti-rotation post, with the anti-rotation post inserted into the anti-rotation groove.

[0089] By engaging the second anti-rotation portion 424 of the movable decorative part body 42 with the first anti-rotation portion 415 of the movable bracket 41, the movable decorative part body 42 can be prevented from rotating relative to the movable bracket 41, thereby preventing wear between the movable decorative part body 42 and the movable bracket 41 due to friction, which is beneficial to further extend the service life of the camera module 100.

[0090] Optionally, such as Figure 12 and Figure 13 As shown, the connector 91 includes a first limiting part 911 and a second limiting part 912. The first limiting part 911 is limited and engaged with the movable decorative body 42 in the direction away from the movable appearance surface 425 and in the direction toward the movable appearance surface 425. The second limiting part 912 is limited and engaged with the movable bracket 41 in the direction toward the movable appearance surface 425.

[0091] For example, such as Figure 12 and Figure 13 As shown, the first limiting part 911 is disposed on the upper side of the second limiting part 912. The first limiting part 911 is positioned downwards and upwards to limit the movement of the movable decorative part body 42, so that the movable decorative part body 42 can move up and down with the connecting part 91. The second limiting part 912 is positioned upwards to limit the movement of the movable bracket 41, so that the connecting part 91 can move upwards with the movable bracket 41, but will not move downwards with the movable bracket 41.

[0092] By providing a first limiting part 911 and a second limiting part 912 on the connector 91, with the first limiting part 911 engaging with the movable decorative part body 42 in both the direction away from and towards the movable exterior surface 425, and the second limiting part 912 engaging with the movable bracket 41 in the direction towards the movable exterior surface 425, it is convenient to connect the connector 91 to the movable decorative part body 42, and to facilitate the movement of the movable bracket 41 relative to the connector 91 in the direction away from the movable exterior surface 425.

[0093] Optionally, such as Figures 9 to 13 As shown, the connector 91 includes a connecting rod 913, a first protrusion, and a second protrusion. The first and second protrusions are respectively located at both ends of the connecting rod 913 and both protrude from the outer peripheral surface of the connecting rod 913. The first protrusion forms a first limiting portion 911, and the second protrusion forms a second limiting portion 912. The movable bracket 41 is provided with a first limiting groove 4122, and the first protrusion is located within the first limiting groove 4122. The second limiting groove 4222 extends through the movable bracket 41 in a direction opposite to the movable decorative surface. The movable decorative component body 42 is provided with a second limiting groove 4222, and the second protrusion is located within the second limiting groove 4222.

[0094] For example, such as Figure 12 As shown, connector 91 is H-shaped.

[0095] The connector 91 has a simple structure and is easy to manufacture, which helps to further reduce the manufacturing cost of the camera module 100.

[0096] Optionally, such as Figure 4 As shown, there are multiple connectors 91, which are arranged at intervals along the circumference of the movable decorative body 42. Figures 9 to 11 As shown, the first connecting part 412 is provided with a first insertion part 4121 through which the connecting rod 913 passes, and the second connecting part 422 is provided with a second insertion part 4221 through which the connecting rod 913 passes. The first insertion part 4121 and the second insertion part 4221 are insertion slots.

[0097] By inserting the connecting rod 913 into the first plug-in portion 4121 and the second plug-in portion 4221, the connecting member 91 can prevent the movable decorative part body 42 from rotating relative to the movable bracket 41, thereby preventing wear between the movable decorative part body 42 and the movable bracket 41 due to friction, which is beneficial to further extend the service life of the camera module 100.

[0098] Optionally, such as Figure 3As shown, the movable bracket 41 has an annular first sealing portion 413, and the movable decorative part body 42 has an annular second sealing portion 423. The first sealing portion 413 is sleeved on the outside of the second sealing portion 423. The movable decorative part 4 also includes a sealing ring 43, which is disposed between the first sealing portion 413 and the second sealing portion 423 and is in a sealing fit with the first sealing portion 413 and the second sealing portion 423.

[0099] For example, the first sealing part 413 is provided with a sealing groove, the sealing ring 43 is provided in the sealing groove, and the outer peripheral surface of the sealing ring 43 abuts against the second sealing part 423.

[0100] By setting a sealing ring 43 between the movable bracket 41 and the movable decorative body 42, a seal is achieved between the movable bracket 41 and the movable decorative body 42, preventing dust, moisture, etc. from entering the interior of the camera module 100 from between the movable bracket 41 and the movable decorative body 42, thereby improving the reliability of the camera module 100.

[0101] Optionally, such as Figures 2 to 4 As shown, the decorative component also includes an annular second seal 82, which is retractable along the optical axis of the camera module 100, and its two ends are connected to the movable decorative component 4 and the camera bracket 1, respectively.

[0102] For example, such as Figure 11 and Figure 14 As shown, the second sealing part 423 is provided with an annular third sealing surface 4231, and the camera bracket 1 is provided with an annular fourth sealing surface 13. Figure 15 As shown, the second sealing element 82 includes a third connecting edge 821, a fourth connecting edge 822, and a second deformable portion 823. The third connecting edge 821 and the fourth connecting edge 822 are respectively located at opposite ends of the second deformable portion 823, and both are located radially outwards from the second deformable portion 823. The surface of the third connecting edge 821 facing away from the fourth connecting edge 822 is sealed to the third sealing surface 4231, and the surface of the fourth connecting edge 822 facing away from the third connecting edge 821 is sealed to the fourth sealing surface 13. When the movable decorative element 4 moves relative to the fixed decorative element 6 along the optical axis of the camera module 100, the second deformable portion 823 undergoes elastic deformation along the optical axis of the camera module 100. The second deformable portion 823 can be a bellows.

[0103] By setting a second seal 82 between the movable decorative part 4 and the camera bracket 1, a seal can be achieved between the movable decorative part 4 and the camera bracket 1, preventing dust, moisture, etc. from entering the interior of the camera module 100 from between the movable decorative part 4 and the camera bracket 1, thereby improving the reliability of the camera module 100.

[0104] Optionally, such as Figure 2 and Figure 4 As shown, the camera assembly also includes a camera motor 3, which is located inside the cavity 11 and connected to the lens assembly 2. At least a portion of the lens assembly 2 is positioned on one side of the camera motor 3 in the optical axis direction of the camera module 100. The drive mechanism 5 includes a drive device 51 and a transmission mechanism 52. The drive device 51 is connected to the movable decorative piece 4 via the transmission mechanism 52. The movable decorative piece 4 and the transmission mechanism 52 are positioned on the side of the camera motor 3 facing the lens assembly 2 in the optical axis direction of the camera module 100.

[0105] For example, the lens assembly 2 is located above the camera motor 3, and the movable decorative piece 4 and the transmission mechanism 52 are also located above the camera motor 3. This allows the movable decorative piece 4 to be fitted onto the outside of the lens assembly 2.

[0106] Understandably, the radial dimension of the camera motor 3 is typically larger than that of the lens assembly 2. By positioning the movable decorative piece 4 and the transmission mechanism 52 on the side of the camera motor 3 facing the lens assembly 2 along the optical axis of the camera module 100, the movable decorative piece 4 is fitted onto the outside of the lens assembly 2. This fully utilizes the space on the side of the camera motor 3 facing the lens assembly 2, effectively reducing the radial dimensions of the movable decorative piece 4 and the transmission mechanism 52. This helps to reduce the size and weight of the camera module 100, facilitating a lightweight design for the camera module 100.

[0107] Optionally, the drive device 51 is located on one side of the camera motor 3 in a direction perpendicular to the optical axis of the camera module 100, and the drive device 51 is connected to the camera bracket 1.

[0108] For example, such as Figure 1 and Figure 2 As shown, the drive unit 51 is located on the radial side of the camera motor 3.

[0109] By positioning the drive unit 51 on one side of the camera motor 3 in a direction perpendicular to the optical axis of the camera module 100, it is convenient to connect and fix the drive unit 51 to the camera bracket 1.

[0110] Optionally, such as Figure 4 As shown, the driving device 51 includes a first rotating member 511, the rotation axis of which intersects the optical axis of the camera module 100. The transmission mechanism 52 includes a second rotating member 521, the rotation axis of which is consistent with the optical axis of the camera module 100, and the first rotating member 511 and the second rotating member 521 are connected in a transmission manner.

[0111] For example, both the first rotating member 511 and the second rotating member 521 are bevel gears, and the first rotating member 511 meshes with the second rotating member 521. That is, the first rotating member 511 and the second rotating member 521 form a gear transmission pair. The rotation axis of the first rotating member 511 is perpendicular to the vertical direction, and the rotation axis of the second rotating member 521 is consistent with the vertical direction.

[0112] By setting the rotation axis of the first rotating member 511 to intersect with the optical axis of the camera module 100, and setting the rotation axis of the second rotating member 521 to be consistent with the optical axis of the camera module 100, the transmission direction from the first rotating member 511 to the second rotating member 521 can be changed. This facilitates placing the drive device 51 and the transmission mechanism 52 at different positions on the camera assembly along the optical axis of the camera module 100. This simplifies the design of the camera module 100.

[0113] Optionally, such as Figure 4 As shown, the drive device 51 also includes a drive motor 512 and a reducer, with the drive motor 512 being driven by the first rotating member 511. The drive motor 512 is driven by the reducer, and the reducer is driven by the first rotating member 511.

[0114] The reducer is connected to the drive motor 512 to reduce the speed and increase the torque output by the drive motor 512. The reducer is connected to the first rotating part 511 for transmission and serves as the output end of the drive device 51, which is connected to the subsequent transmission mechanism 52.

[0115] Optionally, such as Figure 2 , Figure 4 and Figure 14 As shown, the camera bracket 1 is provided with a first receiving groove 12, and the first rotating member 511 is disposed in the first receiving groove 12.

[0116] By placing the first rotating member 511 in the first receiving groove 12, it is beneficial to improve the compactness of the layout between the first rotating member 511 and the camera bracket 1, and to facilitate the lightweight design of the camera module 100.

[0117] Optionally, such as Figure 4 and Figure 14 As shown, the camera bracket 1 is provided with a second receiving groove 14, and at least a portion of the second rotating member 521 is disposed in the second receiving groove 14.

[0118] By placing at least a portion of the second rotating member 521 within the second receiving groove 14, it is beneficial to improve the compactness of the layout between the second rotating member 521 and the camera bracket 1, and to facilitate the lightweight design of the camera module 100.

[0119] Optionally, the fixed bracket 61 is provided with a limiting surface 613, and the second rotating member 521 is disposed between the bottom wall of the second receiving groove 14 and the limiting surface 613, so as to limit the second rotating member 521 in the optical axis direction of the camera module 100.

[0120] By setting a limiting surface 613 on the fixed bracket 61, it is possible to avoid setting a separate component to limit the second rotating member 521 in the camera module 100, thereby simplifying the structure of the camera module 100 and reducing the cost of the camera module 100.

[0121] like Figure 2 , Figure 4 and Figure 14 As shown, the camera bracket 1 has a light-transmitting hole 15, which is connected to the cavity 11. The camera assembly also includes a lens 10, which covers the light-transmitting hole 15 and is connected to the camera bracket 1.

[0122] Optionally, such as Figure 3 , Figure 4 , Figure 9 and Figure 16 As shown, the second rotating part 521 is sleeved on the outside of the movable decorative part 4. The second rotating part 521 is provided with an internal thread 5211, and the movable decorative part 4 is provided with an external thread 414. The external thread 414 is threadedly connected to the internal thread 5211.

[0123] For example, the movable bracket 41 is provided with an external thread 414, and the second rotating member 521 is threadedly connected to the movable bracket 41. That is to say, a threaded transmission pair is formed between the movable bracket 41 and the second rotating member 521.

[0124] By threading the internal thread 5211 of the second rotating member 521 to the external thread 414 of the movable decorative member 4, it is beneficial to improve the transmission smoothness between the second rotating member 521 and the movable decorative member 4, and improve the reliability of the camera module 100.

[0125] The camera module 100 of this disclosure decouples the decorative component and the camera component, which not only improves the flexibility of the decorative component application but also reduces the production difficulty and manufacturing cost of the camera module 100. Furthermore, by placing the decorative component on the side of the camera motor 3 facing the lens assembly 2, the space on that side of the camera motor 3 facing the lens assembly 2 is fully utilized, improving space utilization and stacking efficiency of the camera module 100.

[0126] When the camera module 100 of this embodiment is in operation, the drive motor 512 drives the first rotating member 511 to rotate forward, and the first rotating member 511 drives the second rotating member 521 to rotate forward. The second rotating member 521 is threadedly connected to the movable bracket 41 to drive the movable bracket 41 to move upward, and the buffer member 92 pushes the movable decorative member body 42 upward, thereby extending the movable decorative member 4. Alternatively, the drive motor 512 drives the first rotating member 511 to rotate in the opposite direction, and the first rotating member 511 drives the second rotating member 521 to rotate in the opposite direction. The second rotating member 521 is threadedly connected to the movable bracket 41 to drive the movable bracket 41 to move downward, and the connecting member 91 pulls the movable decorative member body 42 downward, thereby retracting the movable decorative member 4. When the movable decorative member 4 is in the extended state, the second sealing member 82 is stretched; when the movable decorative member 4 is in the retracted state, the second sealing member 82 is compressed.

[0127] The electronic device of this disclosure includes the camera module 100 described in any of the above embodiments.

[0128] Since the design and manufacturing costs of different models of camera modules 100 are low, the electronic devices of the present disclosure embodiments have advantages such as low cost.

[0129] Optionally, the drive motor 512 is electrically connected to the motherboard of the electronic device, or the drive motor 512 is electrically connected to the circuit board of the camera assembly to provide power to the drive motor 512.

[0130] Optionally, the electronic device includes a housing, and a fixed decorative element body 62 is connected to the housing. The fixed decorative element body 62 is provided with a fifth sealing surface 623, and foam is provided between the fifth sealing surface 623 and the housing.

[0131] Foam is used to achieve a seal between the fixed decorative part body 62 and the housing, preventing dust, moisture and other substances from entering the interior from between the camera module 100 and the housing, thereby improving the reliability of the electronic device.

[0132] Although embodiments of the present disclosure have been shown and described above, it is understood that the above embodiments are exemplary and should not be construed as limiting the present disclosure. Any changes, modifications, substitutions and variations made to the above embodiments by those skilled in the art are within the scope of protection of the present disclosure.
