Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of display, in particular to an electronic device and a sealing ring. BACKGROUND

[0002] With the continuous development of electronic device integration technology, photographing and video shooting have become one of the common functions of electronic devices, so that the application of cameras in electronic devices is becoming more and more widespread. In order to meet the design requirements of thin and light electronic devices, and the requirements of users for shooting angle and focal length, the camera can be extended out of the shell or retracted into the shell as needed. However, there are phenomena such as deviation and sticking during the lifting of the camera, which reduces the service life and reliability of the product. SUMMARY

[0003] The present application provides an electronic device and a sealing ring, which are used to alleviate the problem of unstable lifting of the camera during lifting.

[0004] To achieve the above-mentioned purpose, the present application adopts the following technical scheme:

[0005] In one aspect of the present application, an electronic device is provided, which includes a shell, a base, a camera module, a lifting assembly and a sealing ring assembly. The shell is provided with an opening. A part of the base is located in the opening, and the base is arranged around the inner circle of the opening to form a containing cavity, and the base is connected with the shell. A part of the camera module is located in the shell, and another part of the camera module is arranged through the opening and located in the containing cavity. The part of the camera module located in the containing cavity is used for lifting relative to the shell. The lifting assembly is located in the containing cavity, and the lifting assembly is arranged on the camera module, and the lifting assembly is used for lifting along with the part of the camera module located in the containing cavity. In addition, the sealing ring assembly includes a sealing ring. At least a part of the sealing ring is located in the containing cavity, and the sealing ring is arranged between the lifting assembly and the base. In the direction of the optical axis of the camera module, the sealing ring includes a first annular part and a second annular part connected with each other. The first annular part is connected with the lifting assembly, and the second annular part is connected with the base. The stiffness of the first annular part and the second annular part is different.

[0006] In summary, the accommodating cavity surrounded by the base can accommodate the camera module and the lifting assembly. During the lifting of the camera module relative to the shell, part of the camera module can protrude out of the opening on the shell or part of the camera can be retracted into the opening, so as to achieve the purpose of reducing the thickness of the entire electronic device, changing the shooting angle, focal length, etc. The lifting assembly is arranged on the camera module, and the lifting assembly can follow the lifting of the camera module, so that the lifting assembly can protect the camera module while avoiding the movement of the camera module and avoiding interference with the movement of the camera module. In addition, the sealing ring located in the accommodating cavity is arranged between the lifting assembly and the base. Along the optical axis direction of the camera module, the sealing ring includes a first annular portion and a second annular portion connected with each other, and the first annular portion and the second annular portion can be arranged in layers. The first annular portion is connected with the lifting assembly, the second annular portion is connected with the base, and the first annular portion and the second annular portion are connected, so that the gap between the lifting assembly and the base can be sealed by the sealing ring assembly to prevent external water vapor or impurities from entering the electronic device.

[0007] Based on this, when the lifting assembly follows the camera module and lifts relative to the base along the optical axis direction of the camera module, the sealing ring can be stretched or compressed, so that the sealing ring deforms. Since the first annular portion and the second annular portion are arranged in layers along the optical axis direction of the camera module, and the stiffness of the first annular portion and the second annular portion is different, therefore, during the lifting of the lifting assembly along the optical axis direction of the camera module, the component with smaller stiffness in the first annular portion and the second annular portion will deform first, and the component with larger stiffness will deform later, to realize segmented deformation. The length (dimension along the optical axis direction of the camera module) of the first annular portion and the second annular portion is smaller than the length (dimension along the optical axis direction of the camera module) of the entire sealing ring. In this way, compared with the deformation of the entire sealing ring, the deformation amount of each part of the first annular portion or the second annular portion during the deformation of the first annular portion or the second annular portion is approximately the same, so as to reduce the probability of buckling phenomenon of the first annular portion or the second annular portion during the deformation, and further reduce the probability of the above buckling phenomenon of the entire sealing ring, to alleviate the unstable phenomena such as deviation and jamming of the lifting assembly during the lifting, and to solve the problem of unstable lifting of the camera module.

[0008] In one optional embodiment, the sealing ring further includes a third annular portion located between and connected to the first and second annular portions. The stiffness of the third annular portion lies between that of the first and second annular portions. This third annular portion provides a transition between the stiffness of the first and second annular portions, allowing for a smooth transition in the overall stiffness of the sealing ring from the first annular portion to the second annular portion (or vice versa). In this way, during deformation, the third annular portion can buffer the deformation difference between the first and second annular portions, reducing stress concentration at the connection point.

[0009] In one optional embodiment, the diameter of the first annular portion is smaller than the diameter of the second annular portion. In this case, the first annular portion can contract inward relative to the second annular portion. Thus, when setting the structural dimensions of the base, the portion of the base surrounding the second annular portion can also contract inward, thereby forming an accommodating space on the outer side of the aforementioned receiving cavity sidewall. Based on this, when the aforementioned electronic device also includes an external device, the external device can be disposed within the aforementioned accommodating space, thereby making the overall structure of the electronic device more compact and facilitating product miniaturization design.

[0010] In one optional implementation, when the external device has a large dimension along the optical axis of the camera module, the length of the first annular portion can be greater than the length of the second annular portion, thereby enabling the accommodating space to accommodate the external device.

[0011] In one optional embodiment, the sidewall of the third annular portion is S-shaped. The portion where the sidewall of the third annular portion connects to the first annular portion is a first bend, which protrudes in a direction away from the first annular portion. The portion where the sidewall of the third annular portion connects to the second annular portion is a second bend, which also protrudes in a direction away from the second annular portion. In this way, the S-shaped third annular portion can connect to the smaller-diameter first annular portion via the upwardly protruding first bend. Furthermore, the larger-diameter second annular portion is connected via the downwardly protruding second bend, allowing the third annular portion to transition between the inner diameters of the first and second annular portions. Additionally, when the sealing ring changes shape, the protruding first and second bends can disperse stress, thereby reducing stress concentration.

[0012] In one optional embodiment, the first annular portion has a first wall thickness H1, and the second annular portion has a second wall thickness H2. The first bent portion has a first included angle α1, and the second bent portion has a second included angle α2. Wherein, H1 > H2, and α1 < α2. In this case, the upward-protruding angle formed by the first bent portion (i.e., α1) is small, allowing a portion of the first annular portion connected to the first bent portion to be approximately or completely vertical. Furthermore, the downward-protruding angle formed by the second bent portion (i.e., α2) is large, causing a portion of the second annular portion connected to the second bent portion to tilt outwards. Thus, when α1 < α2, the pre-deformation of the third annular portion with an S-shaped sidewall makes the tilted second annular portion more prone to deformation than the vertically positioned first annular portion. As can be seen from the above, the second annular portion with lower stiffness will deform first. Therefore, the second annular portion that deforms first is more easily stretched under the action of the lifting assembly, making it easier for the lifting assembly to lift.

[0013] In one optional embodiment, the wall thickness of the third annular portion gradually decreases from H1 to H2 from the first bend to the second bend. This makes the corners formed by the S-shaped third annular portion at the locations of the protruding first and second bends smoother. When the sealing ring changes, the aforementioned first and second bends are more conducive to effective stress dispersion, thereby reducing stress concentration.

[0014] In one optional embodiment, the first annular portion has a first wall thickness H1, and the second annular portion has a second wall thickness H2. The first bent portion has a first included angle α1, and the second bent portion has a second included angle α2. Wherein, H1 < H2, α1 > α2. In this case, the upward-protruding angle formed by the first bent portion (i.e., α1) is larger, causing a portion of the first annular portion connected to the first bent portion to tilt outwards. Furthermore, the downward-protruding angle formed by the second bent portion (i.e., α2) is smaller, allowing a portion of the second annular portion connected to the second bent portion to be approximately or completely vertically positioned. Thus, when α1 > α2, the pre-deformation of the third annular portion with an S-shaped sidewall makes the tilted first annular portion more prone to deformation than the vertically positioned second annular portion. As can be seen from the above, the first annular portion with lower stiffness will deform first. Therefore, the first annular portion that deforms first is more easily stretched under the action of the lifting assembly, making it easier for the lifting assembly to lift.

[0015] In one optional embodiment, the wall thickness of the third annular portion gradually increases from H1 to H2 from the first bend to the second bend. Similarly, the gradually changing wall thickness of the third annular portion makes the corners formed at the locations of the protruding first and second bends in the S-shaped third annular portion more rounded. When the sealing ring changes, the aforementioned first and second bends are more conducive to the effective dispersion of stress, thereby reducing stress concentration.

[0016] In one optional embodiment, 0.01mm ≤ H1 ≤ 0.5mm, and 0.01mm ≤ H2 ≤ 0.5mm. In this case, when the first wall thickness H1 or the second wall thickness H2 is less than 0.01mm, the processing precision requirements are high, which is not conducive to cost reduction. Furthermore, when the first wall thickness H1 or the second wall thickness H2 is greater than 0.5mm, the overall thickness of the sealing ring is relatively thick, which is not conducive to achieving miniaturized and thinner design requirements.

[0017] In one optional embodiment, there is a thickness difference ΔH between the first wall thickness H1 and the second wall thickness H2. Where ΔH = |H1 - H2|; 0.02 mm ≤ ΔH ≤ 0.07 mm. In this case, when the thickness difference ΔH is less than 0.02 mm, the stiffness difference between the first annular portion and the second annular portion is small, which is not conducive to the segmented deformation of the sealing ring. Furthermore, when the thickness difference ΔH is greater than 0.07 mm, the thickness of the larger annular portion is too large, which is not conducive to achieving the design requirements of miniaturization and thinness.

[0018] In one optional embodiment, the wall thickness of each of the aforementioned annular portions of the sealing ring can be the same, but the materials can be different, or the stiffness of each annular portion of the sealing ring can be set differently.

[0019] In one optional embodiment, along the optical axis of the camera module, the first annular portion includes a first sub-ring structure and a second sub-ring structure connected together, with the first sub-ring structure having different stiffnesses than the second sub-ring structure. For example, the wall thicknesses of the first and second sub-ring structures can be different. Alternatively, the wall thicknesses of the first and second sub-ring structures can be the same, but the materials used are different. Similarly, during the deformation of the sealing ring, the first and second sub-ring structures do not need to deform simultaneously, thus enabling the first annular portion to achieve segmented deformation and further improve deformation stability. Alternatively, along the optical axis of the camera module, the second annular portion includes a third and a fourth sub-ring structure connected together; the stiffnesses of the third and fourth sub-ring structures are different. Similarly, the wall thicknesses of the third and fourth sub-ring structures can be different. Alternatively, the wall thicknesses of the third and fourth sub-ring structures can be the same, but the materials used are different. Similarly, during the deformation of the sealing ring, the third and fourth sub-ring structures do not need to deform simultaneously, thus enabling the second annular portion to achieve segmented deformation.

[0020] In one optional embodiment, the lifting assembly includes a lifting cover and a first connecting structure. The lifting cover is mounted on the camera module, and the first connecting structure is located at the end of the lifting cover facing away from the light-incident surface of the camera module. The first connecting structure is arranged around the lifting cover and is connected to the lifting cover. Furthermore, the sealing ring assembly includes a first metal ring located between the first annular portion and the first connecting structure. A portion of the first annular portion covers the surface of the first metal ring facing away from the first connecting structure. The first metal ring is connected to the first connecting structure and the first annular portion. The stiffness of the first metal ring is greater than the stiffness of the first annular portion. Therefore, the surface of the first metal ring facing the first connecting structure (i.e., the lower surface) and the surface of the first metal ring facing the first annular portion (i.e., the upper surface) have good flatness, thereby allowing the first metal ring to adhere more tightly to the first annular portion and the first connecting structure, improving the reliability of the connection.

[0021] In one optional embodiment, the base includes a receiving structure and a second connecting structure. The receiving structure is arranged around the inner ring of the opening to form a receiving cavity. The second connecting structure is located at the end of the receiving structure facing the light-incident surface of the camera module. The second connecting structure is arranged around the receiving structure and is connected to the receiving structure. Furthermore, the sealing ring assembly includes a second metal ring, which is located on the surface of the second connecting structure facing the light-incident surface of the camera module and is connected to the second connecting structure. The second metal ring includes a first surface facing the second connecting structure and a second surface facing away from the second connecting structure. The end of the second annular portion facing away from the third annular portion covers a portion of the first surface and a portion of the second surface, as well as the inner annular surface of the second metal ring. Similarly, the good flatness of the second metal ring surface can improve the reliability of the connection between the second metal ring and the second connecting structure and the second annular portion. Furthermore, the second metal ring can be connected to the second metal ring by partially covering it, allowing the portion of the second surface of the second metal ring not covered by the second annular portion to connect with other components, thereby improving the space utilization of the second surface of the second metal ring and facilitating the miniaturization design of the product.

[0022] In one alternative embodiment, the electronic device further includes a decorative cover. This decorative cover is disposed around the perimeter of the lifting assembly. The decorative cover is connected to the portion of the second surface of the second metal ring that is not covered by the second annular portion. In this way, the decorative cover can decorate the outer surface of the lens cover assembly, meeting relevant aesthetic design requirements. Furthermore, the connection between the decorative cover and the portion of the second surface of the second metal ring that is not covered by the second annular portion improves the space utilization of the second surface.

[0023] In one optional embodiment, the base includes a receiving structure and a second connecting structure. The receiving structure is disposed around the inner circle of the opening, forming a receiving cavity. The second connecting structure is located at the end of the receiving structure facing the light-incident surface of the camera module. The second connecting structure is disposed around the receiving structure and is connected to the receiving structure. Furthermore, the sealing ring assembly includes a second metal ring located between the second annular portion and the second connecting structure. A portion of the second annular portion covers the surface of the second metal ring facing away from the second connecting structure, and the second metal ring is connected to the second connecting structure and the second annular portion. Similarly, the upper and lower surfaces of the second metal ring can have good flatness, which can improve the reliability of the connection between the second metal ring and the second connecting structure and the second annular portion.

[0024] In another aspect, this application provides a sealing ring. The sealing ring includes a first annular portion and a second annular portion stacked and connected to each other. The first and second annular portions have different stiffnesses. In this case, due to the difference in stiffness between the first and second annular portions, when the sealing ring is subjected to deformation, the component with lower stiffness in the first and second annular portions will deform first, while the component with higher stiffness will deform later, thus achieving segmented deformation. The length of the first and second annular portions (the dimension along the stacking direction of the first and second annular portions) is less than the length of the entire sealing ring (the dimension along the stacking direction of the first and second annular portions). In this way, relative to the deformation of the entire sealing ring, the deformation of each part of the first or second annular portion can be approximately the same during deformation, thereby reducing the probability of buckling during the deformation of the first or second annular portion, and further reducing the probability of buckling of the entire sealing ring, thus mitigating instability such as displacement and jamming during the movement of components connected to the sealing ring.

[0025] In one optional embodiment, the sealing ring further includes a third annular portion located between and connected to the first and second annular portions. The stiffness of the third annular portion lies between that of the first and second annular portions. This third annular portion provides a transition between the stiffness of the first and second annular portions, allowing for a smooth transition in the overall stiffness of the sealing ring from the first annular portion to the second annular portion (or vice versa). In this way, during deformation, the third annular portion can buffer the deformation difference between the first and second annular portions, reducing stress concentration at the connection point.

[0026] In one alternative embodiment, the diameter of the first annular portion is smaller than the diameter of the second annular portion. In this case, the first annular portion can contract inward relative to the second annular portion. This allows other components arranged around the periphery of the second annular portion to also contract inward, thereby forming an accommodating space. An external device can be disposed within this accommodating space, making the structure of the electronic device with the aforementioned sealing ring more compact and facilitating product miniaturization.

[0027] In one optional embodiment, the sidewall of the third annular portion is S-shaped. The portion where the sidewall of the third annular portion connects to the first annular portion is a first bend, which protrudes in a direction away from the first annular portion. The portion where the sidewall of the third annular portion connects to the second annular portion is a second bend, which also protrudes in a direction away from the second annular portion. In this way, the S-shaped third annular portion can connect to the smaller-diameter first annular portion via the upwardly protruding first bend. Furthermore, the larger-diameter second annular portion is connected via the downwardly protruding second bend, allowing the third annular portion to transition between the inner diameters of the first and second annular portions. Additionally, when the sealing ring changes shape, the protruding first and second bends can disperse stress, thereby reducing stress concentration.

[0028] In one optional embodiment, the first annular portion has a first wall thickness H1, and the second annular portion has a second wall thickness H2. The first bent portion has a first included angle α1, and the second bent portion has a second included angle α2. Wherein, H1 > H2, and α1 < α2. In this case, the upward-protruding angle formed by the first bent portion (i.e., α1) is small, allowing a portion of the first annular portion connected to the first bent portion to be approximately or completely vertical. Furthermore, the downward-protruding angle formed by the second bent portion (i.e., α2) is large, causing a portion of the second annular portion connected to the second bent portion to tilt outwards. Thus, when α1 < α2, the pre-deformation of the third annular portion with an S-shaped sidewall makes the tilted second annular portion more prone to deformation than the vertically positioned first annular portion. As can be seen from the above, the second annular portion with lower stiffness will deform first. Therefore, the second annular portion that deforms first is more easily stretched, making the component connected to the sealing ring easier to move.

[0029] In one optional embodiment, the wall thickness of the third annular portion gradually decreases from H1 to H2 from the first bend to the second bend. This makes the corners formed by the S-shaped third annular portion at the locations of the protruding first and second bends smoother. When the sealing ring changes, the aforementioned first and second bends are more conducive to effective stress dispersion, thereby reducing stress concentration.

[0030] In one optional embodiment, the first annular portion has a first wall thickness H1, and the second annular portion has a second wall thickness H2. The first bent portion has a first included angle α1, and the second bent portion has a second included angle α2. Wherein, H1 < H2, α1 > α2. In this case, the upward-protruding angle formed by the first bent portion (i.e., α1) is larger, causing a portion of the first annular portion connected to the first bent portion to tilt outwards. Furthermore, the downward-protruding angle formed by the second bent portion (i.e., α2) is smaller, allowing a portion of the second annular portion connected to the second bent portion to be approximately or completely vertically positioned. Thus, when α1 > α2, the pre-deformation of the third annular portion with an S-shaped sidewall makes the tilted first annular portion more prone to deformation than the vertically positioned second annular portion. As can be seen from the above, the first annular portion with lower stiffness will deform first. Therefore, the first annular portion that deforms first is more easily stretched, making the component connected to the sealing ring easier to move.

[0031] In one optional embodiment, the wall thickness of the third annular portion gradually increases from H1 to H2 from the first bend to the second bend. Similarly, the gradually changing wall thickness of the third annular portion makes the corners formed at the locations of the protruding first and second bends in the S-shaped third annular portion more rounded. When the sealing ring changes, the aforementioned first and second bends are more conducive to the effective dispersion of stress, thereby reducing stress concentration.

[0032] In one optional embodiment, 0.01mm ≤ H1 ≤ 0.5mm, and 0.01mm ≤ H2 ≤ 0.5mm. In this case, when the first wall thickness H1 or the second wall thickness H2 is less than 0.01mm, the processing precision requirements are high, which is not conducive to cost reduction. Furthermore, when the first wall thickness H1 or the second wall thickness H2 is greater than 0.5mm, the overall thickness of the sealing ring is relatively thick, which is not conducive to achieving miniaturized and thinner design requirements.

[0033] In one optional embodiment, there is a thickness difference ΔH between the first wall thickness H1 and the second wall thickness H2. Where ΔH = |H1 - H2|; 0.02 mm ≤ ΔH ≤ 0.07 mm. In this case, when the thickness difference ΔH is less than 0.02 mm, the stiffness difference between the first annular portion and the second annular portion is small, which is not conducive to the segmented deformation of the sealing ring. Furthermore, when the thickness difference ΔH is greater than 0.07 mm, the thickness of the larger annular portion is too large, which is not conducive to achieving the design requirements of miniaturization and thinness.

[0034] In another aspect, this application provides a sealing ring assembly, which includes any of the sealing rings described above. This sealing ring assembly has the same technical effects as the aforementioned sealing rings, and will not be repeated here.

[0035] In one optional embodiment, the sealing ring assembly further includes a first metal ring connected to the first annular portion. The stiffness of the first metal ring is greater than that of the first annular portion. Therefore, the surface of the first metal ring facing the first annular portion has good flatness, which allows the first metal ring to adhere more tightly to the first annular portion, improving the reliability of the connection.

[0036] In one optional embodiment, the sealing ring assembly further includes a second metal ring. One end of the second annular portion faces away from the third annular portion, and covers a portion of the upper surface and lower surface of the second metal ring, as well as the inner annular surface of the second metal ring. Similarly, the good flatness of the second metal ring surface can improve the reliability of the connection between the second metal ring and the second annular portion. Furthermore, the second metal ring can be connected to the second metal ring by partially wrapping it, thereby allowing the portion of the second metal ring not covered by the second annular portion to connect with other components, improving space utilization and facilitating miniaturization design of the product.

This electronic device can be applied to various communication systems or protocols, such as Bluetooth (BT) communication technology, Global Positioning System (GPS) communication technology, Global System for Mobile Communication (GSM) communication technology, Wireless Fidelity (WiFi) communication technology, Wideband Code Division Multiple Access (WCDMA) communication technology, Long Term Evolution (LTE) technology, 5G communication technology, and other future communication technologies.

[0075] The electronic devices in this application embodiment can be mobile phones, tablets, laptops, smart home devices, smart wearable devices (e.g., smartwatches, smart bracelets, smart glasses, smart helmets), virtual reality (VR) electronic devices, augmented reality (AR) electronic devices, etc. Electronic devices can also be handheld devices with wireless communication capabilities, computing devices or other processing devices connected to a wireless modem, in-vehicle devices, electronic devices in 5G networks, or electronic devices in future evolved public land mobile networks (PLMNs), etc., and this application embodiment is not limited to these categories.

[0076] In some embodiments, in order to enable the above-mentioned electronic device to perform a display function, such as Figure 1 As shown, the electronic device 01 provided in this application embodiment may include a display screen 02, a rear cover 03 located on the back of the display screen 02 (distributed opposite to the display surface of the display screen 02), and a mid-frame 04 located between the display screen 02 and the rear cover 03. The mid-frame 04 can support the display screen 02.

[0077] The display screen 02 can be a liquid crystal display (LCD), an organic light emitting diode (OLED) display, a micro (or mini) light-emitting diode (LED) display, or a quantum dot light-emitting diode (QLED) display, etc. This application does not limit the type of the above-mentioned display screen.

[0078] The aforementioned electronic device 01 may further include a processor 05 electrically connected to the display screen 02. The processor 05 may be disposed on the side of the middle frame 04 away from the display screen 02. The rear cover 03 is fastened to the middle frame 04, thereby forming an installation space between the rear cover 03 and the middle frame 04 for accommodating the processor 05, battery, and other devices. The processor 05 can provide display data to the display screen 02 to drive the display screen 02 to display images.

[0079] For example, the processor 05 described above may include one or more processing units, such as: an application processor (AP), a modem processor, a graphics processing unit (GPU), an image signal processor (ISP), a controller, a video codec, a digital signal processor (DSP), a baseband processor, and / or a neural network processing unit (NPU), etc. The different processing units may be independent devices or integrated into one or more processors.

[0080] In addition, the aforementioned electronic device 01 may also include a gyroscope sensor, a Hall sensor, an external memory interface, an internal memory, a universal serial bus (USB) interface, a charging management module, a power management module, a battery, an antenna, a mobile communication module, a wireless communication module, an audio module, a speaker, a receiver, a microphone, a headphone jack, a sensor module, buttons, and a camera, all electrically connected to the processor 05. The sensor module may include pressure sensors, gyroscope sensors, barometric pressure sensors, magnetic sensors, accelerometers, distance sensors, proximity sensors, fingerprint sensors, temperature sensors, touch sensors, ambient light sensors, and bone conduction sensors, etc.

[0081] In some embodiments, in order to enable the above-mentioned electronic device 01 to realize image acquisition, i.e., shooting function, the electronic device 01 provided in the above-mentioned embodiments of this application may further include a camera module 10, which may be a front camera module or a rear camera module. Taking a rear camera module as an example, the rear shell 03 is connected to the middle frame 04 to form a housing 08, and a part of the camera module 10 is disposed in the housing 08.

[0082] For example, when the camera module 10 is a rear-facing camera module, the rear shell 03 of the housing 08 has an opening 06 for exposing part of the camera module 10, and another part of the camera module 10 can pass through the opening 06. Alternatively, when the camera 10 is a front-facing camera module, the opening 06 can be formed on the middle frame 04 and the display screen 02 of the housing 08. For ease of explanation, the following examples all use the case where the camera module 10 is a rear-facing camera module and the rear shell 03 has an opening 06.

[0083] In addition, continue as Figure 1 As shown, the electronic device 01 also includes a lens cap assembly 20. (As indicated...) Figure 2 As shown, the lens cap assembly 20 can be fitted onto the camera module 10 to protect it. The lens cap assembly 20 has an image aperture 07 for exposing the lens of the camera module 10. The centerline of the image aperture 07 can be completely or nearly completely aligned with the optical axis O1-O2 of the camera module 10.

[0084] The camera module 10 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. Furthermore, when the camera module 10 can achieve zoom and focus, the movement direction of the optical lens in the camera module 10 can be consistent with the optical axis direction of the optical lens. Alternatively, the movement direction of the optical lens in the camera module 10 can be perpendicular to the optical axis direction of the optical lens (e.g., in a periscope camera), and this application does not limit this. Moreover, this application does not limit the number of camera modules 10. Figure 1 This example illustrates the concept of a rear camera module, which includes one camera module 10.

[0085] For ease of explanation, the following description assumes that the movement direction of the optical lens in the camera module 10 is consistent with the optical axis direction of the optical lens. In some embodiments of this application, such as Figure 3As shown, the camera module 10 may include a variable aperture 11, a lens assembly 12, and a motor 13. For ease of description, an XYZ coordinate axis is established in the accompanying drawings, where the Z direction can be the optical axis O1-O2 direction of the camera module 10 (the optical axis direction of the lens assembly 12). The XY plane formed by the X and Y directions can be perpendicular to the optical axis O1-O2 direction of the lens assembly 12.

[0086] For example, the lens assembly 12 may include one or more optical lenses, enabling the lens assembly 12 with the optical lenses to utilize the refraction principle of the optical lenses to converge the light from the photographed object onto the focal plane of the camera module 10 for imaging. The variable aperture 11 is disposed on the light-incident side of the lens assembly 12. The variable aperture 11 has an adjustable aperture hole 100, and by changing the size of the aperture hole 100, the amount of light entering the camera module 10 can be adjusted. In this case, the surface of the variable aperture 11 facing away from the motor 13 can serve as the light-incident surface S0 of the camera module 10. Alternatively, in some embodiments, when the camera module 10 is a fixed aperture camera, the variable aperture 11 may not be provided in the camera module. In this case, the surface of the lens assembly 12 facing away from the motor 13 can serve as the light-incident surface S0 of the camera module 10.

[0087] In addition, continue as Figure 3 As shown, motor 13 can drive lens assembly 12 to move up and down in the Z direction to achieve zoom and autofocus (AF). As described above, lens cap assembly 20 can cover the camera module 10. Therefore, during the movement of lens assembly 12 in the Z direction, to avoid interfering with the movement of lens assembly 12, a portion of lens cap assembly 20 needs to move up and down with the camera module to avoid obstructing the movement of lens assembly 12.

[0088] The structure of the lens cap assembly 20 is illustrated below. In some embodiments of this application, such as... Figure 4 As shown, the lens cap assembly 20 may include a base 21, a lifting assembly 22, and a sealing ring assembly 23. Based on this, as... Figure 5 As shown, a portion of the base 21 can be located within the opening 06, and the base can be arranged around the inner circumference of the opening 06 on the rear housing 03 to form a receiving cavity 210. This receiving cavity 210 communicates with the opening 06. Furthermore, the base 21 can be connected to the rear housing 03 in the housing 08. For example, the base 21 can be fixed to the rear housing 03 away from the display screen 02 by adhesive, threaded connection, or snap-fit. Figure 1 On the surface shown. In this way, the base 21 can... Figure 3 The entire lens cap assembly 20 shown is fixed to the housing 08.

[0089] In addition, such as Figure 6 (for the following) Figure 2 As shown in the cross-sectional view obtained by cutting along the dashed lines A1-A2, a portion of the camera module 10 (e.g., at least a portion of the motor 13 and lens assembly 12) is located within the housing 08, while another portion of the camera module 10 (e.g., a portion of the lens assembly 12) passes through the opening 06 and is located within the receiving cavity 210. In this case, the portion of the camera module 10 located within the receiving cavity 210 is used for lifting and lowering relative to the housing 08. For example, driven by the motor 13, at least a portion of the lens assembly 12 in the camera module 10 can be lifted and lowered relative to the housing 08 in the Z direction.

[0090] For example, such as Figure 7 (for the following) Figure 2 As shown in another cross-sectional view obtained by cutting along the dashed lines A1-A2, when the camera module 10 is in the first state (e.g., non-shooting state), the lens assembly 12 can be retracted into the opening 06. This ensures that the lens assembly 12 does not protrude from the housing 08 (e.g., the rear housing 03 is away from the surface of the display screen 02), thereby reducing the size of the electronic device along the Z direction. Alternatively, a portion of the lens assembly 12 can be retracted into the opening 06 along the Z direction, so that the lens assembly 12 protrudes only slightly from the housing 08.

[0091] Furthermore, when the camera module 10 is in the second state (e.g., shooting state), such as Figure 8 (for the following) Figure 2 As shown in another cross-sectional view obtained by cutting along the dashed lines A1-A2, a portion of the lens assembly 12 can extend out of the opening 06 along the Z direction, so that the lens assembly 12 can protrude out of the housing 08.

[0092] The above is an example illustrating the situation where the first state is a non-shooting state and the second state is a shooting state. When the camera module 10 is in shooting state, it can perform standard focal length shooting, wide-angle shooting, telephoto shooting, or super telephoto shooting. In some other embodiments of this application, both the first and second states can be shooting states, but the focal lengths can be different. For example, when the camera module 10 is in the first state, it can perform standard focal length shooting or wide-angle shooting. When the camera module 10 is in the second state, it can perform telephoto or super telephoto shooting. The above is merely an example illustrating the first and second states, and this application does not limit them.

[0093] Continue as Figure 6As shown, the lifting assembly 22 can be located within the receiving cavity 210 of the base 21, and the lifting assembly 22 can cover the camera module 10. The lifting assembly 22 has a through hole for exposing the camera module 10. The lifting assembly 22 can protect the camera module 10, reducing the risk of direct impact between the camera module 10 and external objects during use. Furthermore, the lifting assembly 22 is used to move up and down with the portion of the camera module 10 located within the receiving cavity 210 (e.g., at least a portion of the lens assembly 12 mentioned above).

[0094] For example, when the motor 13 in the camera module 10 drives at least a portion of the lens assembly 12 to rise relative to the base 21 in the Z direction, the lifting component 22 will follow the lens assembly 12 to rise in the Z direction. Alternatively, as another example, when the motor 13 in the camera module 10 drives at least a portion of the lens assembly 12 to descend relative to the base 21 in the Z direction, the lifting component 22 will follow the lens assembly 12 to descend in the Z direction. Therefore, during the lifting and lowering of the lens assembly 12, the distance between the lens assembly 12 and the lifting component 22 in the Z direction can remain constant, thereby preventing the lifting component 22 from interfering with the movement of the lens assembly 12. The lens cover assembly 20 may include a driver connected to the lifting component 22, which can drive the lifting component 22 to rise and fall with the lens assembly 12.

[0095] Based on this, such as Figure 9 (for the following) Figure 2 As shown in another cross-sectional view obtained by cutting along the dashed lines A1-A2, the sealing ring assembly 23 may include a sealing ring 230, at least a portion of which is located within the receiving cavity 210 of the base 21. Furthermore, the sealing ring 230 may be disposed between the lifting assembly 22 and the base 21. In this way, the sealing ring assembly 23 can seal the gap between the lifting assembly 22 and the base 21, preventing external moisture or impurities from entering the electronic device through this gap.

[0096] In addition, continue as Figure 10 As shown, along the optical axis O1-O2 of the camera module, for example, from bottom to top along the Z direction, the sealing ring 230 may include a first annular portion 2301 and a second annular portion 2302 connected to each other. In this case, the first annular portion 2301 and the second annular portion 2302 are stacked along the Z direction. Furthermore, as... Figure 11 (for Figure 9 As shown in an enlarged view at point B in the diagram, the first annular portion 2301 can be connected to the lifting assembly 22. The second annular portion 2302 can be connected to the base 21.

[0097] For example, the first annular portion 2301 is located away from the second annular portion 2302 at one end, that is, the lower end of the first annular portion 2301 is connected to the lifting assembly 22. The first annular portion 2301 can be connected to the lifting assembly 22 by adhesive dispensing. Similarly, the second annular portion 2302 is located away from the first annular portion 2301 at one end, that is, the upper end of the second annular portion 2302 is connected to the base 21. Likewise, the second annular portion 2302 and the base 21 can be connected by adhesive dispensing. In this case, of the stacked first annular portion 2301 and second annular portion 2302, the lower first annular portion 2301 is connected to the lifting assembly 22, and the upper second annular portion 2302 is connected to the base 21.

[0098] Based on this, when Figure 6 The lifting assembly 22 shown follows a part of the camera module 10 (e.g., lens assembly 12) and moves up and down relative to the base 21 along the optical axis O1-O2 of the camera module. During this process, it can stretch or compress the sealing ring 230, causing the sealing ring 230 to deform.

[0099] The deformation process of the sealing ring 230 is illustrated below with an example. For example, as shown... Figure 12 (for the following) Figure 2 As shown in another sectional view obtained by cutting along the dashed lines A1-A2, when the lifting assembly 22 and the base 21 do not move relative to each other, the sealing ring 230 is in its initial state. At this time, the sealing ring 230 does not deform. Furthermore, as... Figure 13 (for the following) Figure 2 As shown in the cross-sectional view obtained by cutting along the dashed lines A1-A2 in the diagram, when the lifting assembly 22 rises along the Z direction following the lens assembly 12, the lower part of the sealing ring 230 (i.e., Figure 11 The first annular portion 2301 gradually approaches the upper portion of the sealing ring 230 (i.e., Figure 11 The second annular portion 2302 in the middle, so that the two parts of the sealing ring 230 (the first annular portion 2301 and the second annular portion 2302) are brought close to each other, and the sealing ring 230 is in a state of compression deformation.

[0100] like Figure 14 (for the following) Figure 2 As shown in the cross-sectional view obtained by cutting along the dashed lines A1-A2 in the diagram, when the lifting assembly 22 continues to rise along the Z direction following the lens assembly 12, the lower part of the sealing ring 230 (i.e., Figure 11 The first annular portion 2301 gradually moves away from the portion of the sealing ring 230 that was originally located at the top (i.e., Figure 11The second annular portion 2302 in the middle, so that the two parts of the sealing ring 230 (the first annular portion 2301 and the second annular portion 2302) are far apart from each other, and the sealing ring 230 is in a state of tensile deformation. In addition, when the lifting assembly 22 follows the lens assembly 12 to descend in the Z direction, the deformation process of the sealing ring 230 can be obtained in the same way, which will not be described in detail here.

[0101] The length of the sealing ring 230 (i.e., the dimension along the Z direction) is proportional to the stroke of the lifting assembly 22 (or the stroke of the lens assembly 12). For example, for a camera module 10 with a large stroke (e.g., 6-9 mm), the sealing ring 230 needs to be longer.

[0102] Based on this, in related technologies, such as Figure 15 As shown, when the length (dimension along the Z direction) of the sealing ring 30 needs to meet the requirements of a large-stroke camera module, inconsistent deformation (i.e., buckling) occurs at various points on the sealing ring 30, resulting in unevenly distributed wrinkles 31 in different areas. This increases the risk of stress concentration, thereby reducing the performance of the sealing ring 30. In comparison, the electronic device provided in this application embodiment... Figure 11 The first annular portion 2301 and the second annular portion 2302 shown may have different stiffnesses. In this case, during the lifting process of the lifting assembly 22, the component with lower stiffness in the first annular portion 2301 and the second annular portion 2302 will deform first, while the component with higher stiffness will deform later, so that the sealing ring 230 can achieve segmented deformation.

[0103] Furthermore, since the first annular portion 2301 and the second annular portion 2302 are part of the sealing ring 230, the lengths of the first annular portion 2301 and the second annular portion 2302 (in the lifting direction of the lifting assembly 22, or in the stacking direction of the first annular portion 2301 and the second annular portion 2302, i.e., the Z-direction) are smaller than the length of the entire sealing ring 230 (in the lifting direction of the lifting assembly 22, or in the stacking direction of the first annular portion 2301 and the second annular portion 2302, i.e., the Z-direction). Therefore, relative to the deformation of the entire sealing ring 230, the deformation of each part of the first annular portion 2301 or the second annular portion 2302 can be approximately the same during the deformation process, reducing the probability of stress concentration and thus reducing the probability of buckling during the deformation of the first annular portion 2301 or the second annular portion 2302, thereby achieving the purpose of reducing the buckling of the entire sealing ring 230. This can alleviate the instability caused by the lifting and lowering of the camera module 10 due to the offset and jamming of components connected to the sealing ring 230, such as the lifting assembly 22 during lifting (or movement).

[0104] Based on this, during the lifting assembly 22's lifting and lowering relative to the base 21, in order to reduce the probability of stress concentration at the connection point of the first annular portion 2301 and the second annular portion 2302 when the sealing ring 230 deforms, the sealing ring 230 may further include, for example: Figure 16 (for Figure 9 The third annular portion 2303 is shown in another enlarged view at point B in the figure. This third annular portion 2303 can be located between the first annular portion 2301 and the second annular portion 2302, and is connected to both. The stiffness of the third annular portion 2303 can be between the stiffness of the first annular portion 2301 and the stiffness of the second annular portion 2302.

[0105] In this embodiment, for any one of the first annular portion 2301, the second annular portion 2302, and the third annular portion 2303, when the thickness of the sidewall of the annular portion is equal at all points (i.e., the sidewall thickness is uniform), the stiffness of the annular portion is equal at all points. When the sidewall thickness of the annular portion is not uniform, the stiffness of the annular portion can be the average value of the stiffness at all points. Furthermore, the annular portion is a ring structure with its ends connected. This ring structure can be a circular ring, a triangular ring, a rectangular ring, or other polygonal rings; this application does not limit this. For ease of explanation, the following examples use a circular ring as an example.

[0106] Continue as Figure 16 As shown above, the stiffness of the third annular portion 2303, located between the first annular portion 2301 and the second annular portion 2302, can be between the stiffness of the first annular portion 2301 and the stiffness of the second annular portion 2302. Therefore, the third annular portion 2303 can transition between the stiffness of the first annular portion 2301 and the stiffness of the second annular portion 2302, so that the stiffness of the entire sealing ring 230 smoothly transitions from the first annular portion 2301 to the second annular portion 2302 (or from the second annular portion 2302 to the first annular portion 2301). In this way, during the deformation process of the sealing ring 230, the third annular portion 2303 can buffer the deformation difference between the first annular portion 2301 and the second annular portion 2302, reducing stress concentration at the connection position of the first annular portion 2301 and the second annular portion 2302.

[0107] Furthermore, in some embodiments of this application, such as Figure 17 As shown, the diameter d1 of the first annular portion 2301 in the sealing ring 230 is smaller than the diameter d2 of the second annular portion 2302 (i.e., d1 < d2). This application does not limit the specific values ​​of d1 and d2. In this case, since d1 < d2, the process continues as follows... Figure 16As shown, the first annular portion 2301 can retract inward relative to the lifting assembly of the second annular portion 2302. In this way, other components arranged around the periphery of the second annular portion 2302, such as the portion of the base 21 arranged around the periphery of the second annular portion 2302 (i.e., the portion used to form the sidewall of the receiving cavity 210) when setting the structural dimensions of the base 21, can also retract inward with the lifting assembly, so that the outer side of the sidewall of the receiving cavity 210 (i.e., the side away from the lifting assembly 22) can form an accommodating space 300.

[0108] Based on this, when the aforementioned electronic device also includes Figure 16 When the external device 310 is shown, it can be disposed within the aforementioned accommodating space 300, thereby making the overall structure of the electronic device more compact and facilitating product miniaturization design. This application does not limit the type, structure, or function of the external device 310. Furthermore, when the external device 310 has a larger dimension along the Z direction, the length of the first annular portion 2301 (dimension along the Z direction) can be greater than the length of the second annular portion 2302 (dimension along the Z direction), thereby enabling the accommodating space 300 formed on the outer side of the accommodating cavity 210 sidewall to accommodate the external device 310.

[0109] The above is based on Figure 17 The illustration uses a circular ring as an example, where the first annular portion 2301, the second annular portion 2302, and the third annular portion 2303 in the sealing ring 230 are circular rings. In other embodiments of this application, when the first annular portion 2301, the second annular portion 2302, and the third annular portion 2303 are triangular rings, rectangular rings, or other polygonal rings, in order to achieve the purpose of forming the accommodating space 300, the opening area of ​​the first annular portion 2301 can be smaller than the opening area of ​​the second annular portion 2302.

[0110] As can be seen from the above, if Figure 17 As shown, the third annular portion 2303 in the sealing ring 230 can connect the first annular portion 2301 and the second annular portion 2302, which have different diameters. Therefore, the third annular portion 2303 can not only transition the rigidity of the first annular portion 2301 and the second annular portion 2302, but also transition the inner diameter of the first annular portion 2301 and the second annular portion 2302. The shape of the sidewall of the third annular portion 2303 is illustrated below.

[0111] For example, such as Figure 18 (for Figure 17As shown in an enlarged view at point C, the sidewall of the third annular portion 2303 can be inclined relative to the Z direction. This allows the upper opening size of the third annular portion 2303 to be larger than the lower opening size, enabling the upper end of the third annular portion 2303 to connect to the second annular portion 2302 with a larger diameter (e.g., d2), and the lower end of the third annular portion 2303 to connect to the first annular portion 2301 with a smaller diameter (e.g., d1).

[0112] Or, for example, such as Figure 19 (for Figure 17 As shown in another enlarged view at point C, the sidewall of the third annular portion 2303 is S-shaped. The S-shape of the sidewall of the third annular portion 2303 means that the portion where the sidewall of the third annular portion 2303 connects to the first annular portion 2301 is a first bend 301. This first bend 301 protrudes in a direction away from the first annular portion 2301 (i.e., upward). Furthermore, the portion where the sidewall of the third annular portion 2303 connects to the second annular portion 2302 is a second bend 302, which protrudes in a direction away from the second annular portion 2302 (i.e., downward). Therefore, the upwardly protruding first bend 301 and the downwardly protruding second bend 302 connect to form the aforementioned S-shaped sidewall of the third annular portion 2303.

[0113] In this way, continue as Figure 19 As shown, in the S-shaped third annular portion 2303, a smaller diameter (e.g., d1) first annular portion 2301 can be connected via an upwardly protruding first bend 301. Furthermore, a larger diameter (e.g., d2) second annular portion 2302 is connected via a downwardly protruding second bend 302, thereby allowing the third annular portion 2303 to transition between the inner diameters of the first and second annular portions 2301 and 2302. Moreover, when the sealing ring 230 deforms, the protruding first and second bends 301 and 302 can disperse stress, thereby reducing stress concentration.

[0114] Based on this, for Figure 18 or Figure 19 Regarding the sealing ring 230 shown, in order to make the first annular portion 2301 and the second annular portion 2302 have different stiffnesses, for example, when the materials of the first annular portion 2301 and the second annular portion 2302 are the same, the thicknesses of the first annular portion 2301 and the second annular portion 2302 may be different. In some embodiments, the material of the sealing ring 230 may be silicone, such as fluorosilicone.

[0115] For example, the first annular portion 2301 may have a first wall thickness H1, and the second annular portion 2302 may have a second wall thickness H2. Here, H1 and H2 are different. Based on this, when H1 > H2, the stiffness of the first annular portion 2301 can be greater than the stiffness of the second annular portion 2302. Conversely, when H1 < H2, the stiffness of the first annular portion 2301 can be less than the stiffness of the second annular portion 2302.

[0116] The following description uses the example of an S-shaped sidewall of the third annular portion 2303, combined with the relationship between the wall thickness of the first annular portion 2301 and the wall thickness of the second annular portion 2302, to illustrate the specific shape of the sidewall of the third annular portion 2303 and the method of setting the wall thickness of the third annular portion 2303. In some embodiments of this application, the following continues... Figure 19 As shown, the first bend 301 may have a first included angle α1, and the second bend 302 may have a second included angle α2. The included angle of either the first bend 301 or the second bend 302 refers to the angle of the corner formed by the protrusion of that bend.

[0117] like Figure 19 As shown, when H1 > H2, the stiffness of the first annular portion 2301 is greater than the stiffness of the second annular portion 2302. Therefore, the sealing ring 230, under the action of external forces (e.g., Figure 16 When the lifting component 22 is raised relative to the base 21, the second annular portion 2302, which has less stiffness, will deform first, while the first annular portion 2301, which has greater stiffness, will deform later.

[0118] In addition, continue as Figure 19 As shown, α1 < α2. Therefore, the angle formed by the upward protrusion of the first bending portion 301 (i.e., α1) is small, so that a portion of the first annular portion 2301 connected to the first bending portion 301 can be arranged approximately or completely along the Z direction (i.e., vertically). Furthermore, the angle formed by the downward protrusion of the second bending portion 302 (i.e., α2) is large, so that a portion of the second annular portion 2302 connected to the second bending portion 302 is inclined outward relative to the Z direction.

[0119] In this way, when α1 < α2, the pre-deformation of the S-shaped third annular portion 2303 (including the first bent portion 301 and the second bent portion 302) makes the inclined second annular portion 2302 more prone to deformation than the vertically arranged first annular portion 2301. As can be seen from the above, the second annular portion 2302, with its lower stiffness, will deform first. Therefore, the second annular portion 2302, which deforms first, will be more easily affected by the lifting assembly 22 (such as...). Figure 16 Under the influence of the force (as shown), the components connected to the sealing ring 230, such as the lifting assembly 22, are stretched, making it easier to lift (or move). The above is based on...Figure 16 The example given is that the lifting component 22 is raised relative to the base 21. Similarly, when the lifting component 22 is lowered relative to the base 21, the second annular portion 2302 with lower stiffness is also more prone to phase change.

[0120] Furthermore, as can be seen from the above, Figure 19 The third annular portion 2303 shown can transition the stiffness of the first annular portion 2301 and the second annular portion 2302. Based on this, in order for the third annular portion 2303 to uniformly transition the stiffness of the first annular portion 2301 and the second annular portion 2302, when H1 > H2, the wall thickness of the third annular portion 2303 can gradually decrease from H1 to H2 from the first bending portion 301 to the second bending portion 302.

[0121] This makes the corners formed by the S-shaped third annular portion 2303 at the locations of the protruding first bend 301 and second bend 302 more rounded. When the sealing ring 230 deforms, the aforementioned first bend 301 and second bend 302 are more conducive to the effective dispersion of stress, thereby reducing stress concentration.

[0122] The above example illustrates the specific shape of the sidewall of the third annular portion 2303 and the method of setting the wall thickness of the third annular portion 2303, using the example that H1 > H2, i.e., the stiffness of the first annular portion 2301 is greater than the stiffness of the second annular portion 2302. Alternatively, in other embodiments, such as... Figure 20 (for Figure 17 As shown in another enlarged view at point C, when H1 < H2, the stiffness of the second annular portion 2302 is greater than that of the first annular portion 2301. Therefore, the sealing ring 230, under the action of external forces (e.g., Figure 16 When the lifting component 22 is raised relative to the base 21, the first annular portion 2301 with less stiffness will deform first, while the second annular portion 2302 with greater stiffness will deform later.

[0123] In addition, continue as Figure 20 As shown, α1 > α2. Therefore, the angle formed by the upward protrusion of the first bending portion 301 (i.e., α1) is larger, causing a portion of the first annular portion 2301 connected to the first bending portion 301 to be inclined outward relative to the Z direction. Furthermore, the angle formed by the downward protrusion of the second bending portion 302 (i.e., α2) is smaller, allowing a portion of the second annular portion 2302 connected to the second bending portion 302 to be approximately or completely arranged along the Z direction (i.e., vertically arranged).

[0124] In this way, when α1 > α2, the pre-deformation of the S-shaped third annular portion 2303 (including the first bent portion 301 and the second bent portion 302) makes the inclined first annular portion 2301 more prone to deformation than the vertically arranged second annular portion 2302. As can be seen from the above, the first annular portion 2301, with its lower stiffness, will deform first. Therefore, the first annular portion 2301, which deforms first, will be more easily affected by the lifting assembly 22 (such as...). Figure 16 Under the influence of the force (as shown), the components connected to the sealing ring 230, such as the lifting assembly 22, are stretched, making it easier to lift (or move). The above is based on... Figure 16 The example given is that the lifting component 22 is raised relative to the base 21. Similarly, when the lifting component 22 is lowered relative to the base 21, the first annular portion 2301 with lower stiffness is also more prone to phase change.

[0125] Furthermore, as can be seen from the above, Figure 20 The third annular portion 2303 shown can transition the stiffness of the first annular portion 2301 and the second annular portion 2302. Based on this, in order to ensure that the third annular portion 2303 can uniformly transition the stiffness of the first annular portion 2301 and the second annular portion 2302, when H1 < H2, the wall thickness of the third annular portion 2303 can gradually increase from H1 to H2 from the first bend 301 to the second bend 302. Similarly, the gradually changing wall thickness of the third annular portion 2303 makes the corners formed at the locations of the protruding first bend 301 and second bend 302 of the S-shaped third annular portion 2303 more rounded. When the sealing ring 230 deforms, the aforementioned first bend 301 and second bend 302 are more conducive to the effective dispersion of stress, achieving the purpose of reducing stress concentration.

[0126] Example, Figure 18 , Figure 19 or Figure 20In the sealing ring 230 shown, the dimensional ranges of the first wall thickness H1 of the first annular portion 2301 and the second wall thickness H2 of the second annular portion 2302 can satisfy: 0.01mm ≤ H1 ≤ 0.5mm, 0.01mm ≤ H2 ≤ 0.5mm. In this case, when the first wall thickness H1 or the second wall thickness H2 is less than 0.01mm, the requirement for machining accuracy is high, which is not conducive to cost reduction. Furthermore, when the first wall thickness H1 or the second wall thickness H2 is greater than 0.5mm, the overall thickness of the sealing ring 230 is relatively thick, which is not conducive to achieving miniaturization and thinner design requirements. For example, the first wall thickness H1 or the second wall thickness H2 can be 0.01mm, 0.02mm, 0.03mm, 0.05mm, 0.07mm, 0.1mm, 0.15mm, 0.2mm, 0.25mm, 0.3mm, 0.4mm, or 0.5mm.

[0127] Furthermore, as described above, in order to achieve a stiffness difference between the first annular portion 2301 and the second annular portion 2302, the thickness difference ΔH between the first wall thickness H1 and the second wall thickness H2 can be within the range of 0.02mm ≤ ΔH ≤ 0.07mm. Where ΔH = |H1 - H2|. In this case, when the thickness difference ΔH is less than 0.02mm, the stiffness difference between the first annular portion 2301 and the second annular portion 2302 is small, which is not conducive to the segmented deformation of the sealing ring 230. Furthermore, when the thickness difference ΔH is greater than 0.07mm, the thickness of the larger annular portion in the first annular portion 2301 and the second annular portion 2302 is too thick, which is not conducive to achieving the design requirements of miniaturization and thinness. For example, ΔH can be 0.02mm, 0.03mm, 0.04mm, 0.05mm, 0.06mm, or 0.07mm.

[0128] The above example illustrates the different stiffnesses of the various annular portions of the sealing ring 230, such as the first annular portion 2301, the second annular portion 2302, and the third annular portion 2303, which are made of the same material but have different wall thicknesses. In other embodiments of this application, the wall thicknesses of the various annular portions of the sealing ring 230 can be the same, but the materials can be different, thus achieving a setting where the stiffnesses of the various annular portions of the sealing ring 230 are different.

[0129] The above example illustrates the sealing ring 230 comprising three annular portions with different stiffnesses, namely the first annular portion 2301, the second annular portion 2302, and the third annular portion 2303. In other embodiments of this application, along the optical axis O1-O2 of the camera module, as... Figure 21As shown, the first annular portion 2301 may include a first sub-ring structure 401 and a second sub-ring structure 402 connected together. The stiffness of the first sub-ring structure 401 and the second sub-ring structure 402 are different. For example, the wall thickness of the first sub-ring structure 401 and the second sub-ring structure 402 may be different. Alternatively, the wall thickness of the first sub-ring structure 401 and the second sub-ring structure 402 may be the same, but the materials may be different. Similarly, during the deformation of the sealing ring 230, the first sub-ring structure 401 and the second sub-ring structure 402 do not need to deform simultaneously, thereby enabling the first annular portion 2301 to achieve segmented deformation and further improving deformation stability.

[0130] Similarly, along the optical axis O1-O2 of the camera module, continue as follows... Figure 21 As shown, the second annular portion 2302 may include a connected third sub-ring structure 403 and a fourth sub-ring structure 404. The stiffness of the third sub-ring structure 403 and the fourth sub-ring structure 404 are different. Similarly, the wall thicknesses of the third sub-ring structure 403 and the fourth sub-ring structure 404 may be different. Alternatively, the wall thicknesses of the third sub-ring structure 403 and the fourth sub-ring structure 404 may be the same, but the materials may be different. Similarly, during the deformation of the sealing ring 230, the third sub-ring structure 403 and the fourth sub-ring structure 404 do not need to deform simultaneously, thereby enabling the second annular portion 2302 to achieve segmented deformation.

[0131] Furthermore, in some embodiments of this application, such as Figure 22 (for Figure 9 As shown in another enlarged view at point B in the diagram), the sealing ring assembly 23, in addition to the aforementioned sealing ring 230, may also include a first metal ring 231. The structure of the sealing ring 230 is the same as described above and will not be repeated here. Based on this, the lifting assembly 22 may include a lifting cover 221 and a first connecting structure 222. The lifting cover 221 may cover the camera module 10. The first connecting structure 222 may be located at the end of the lifting cover 221 opposite to the light-incident surface S0 of the camera module 10 (i.e., at the lower end of the lifting cover 221). Figure 23 As shown, the first connecting structure 222 is arranged around the circumference of the lifting cover 221 and is connected to the lifting cover 221. For example, the lifting cover 221 and the first connecting structure 222 can be connected as a single structural component, or they can be connected by adhesive bonding.

[0132] In addition, continue as Figure 22 As shown, the first metal ring 231 can be located between the first annular portion 2301 and the first connecting structure 222. A portion of the first annular portion 2301 covers the surface of the first metal ring 231 facing away from the first connecting structure 222 (i.e., the upper surface of the first metal ring 231). The first metal ring 231 is connected to the first connecting structure 222 and the first annular portion 2301.

[0133] For example, at least a dispensing groove can be formed on the first connecting structure 222, and then glue can be filled into the dispensing groove to connect the first connecting structure 222 to the first metal ring 231. Furthermore, an adhesive layer is provided on the surface of the first metal ring 231 facing away from the first connecting structure 222 (i.e., the upper surface of the first metal ring 231) to cover and connect the first annular portion 2301 to the first metal ring 231. The first annular portion 2301 may completely cover the upper surface of the first metal ring 231, or it may cover only a portion of the upper surface of the first metal ring 231. In this case, the first annular portion 2301 can be connected to the lifting assembly 22 via the first metal ring 231.

[0134] In some embodiments of this application, the first metal ring 231 may be a metal ring made of steel sheet. The stiffness of the first metal ring 231 is greater than that of the first annular portion 2301. Therefore, the surface of the first metal ring 231 facing the first connecting structure 222 (i.e., the lower surface) and the surface of the first metal ring 231 facing the first annular portion 2301 (i.e., the upper surface) have good flatness, which allows the first metal ring 231 to adhere more tightly to the first annular portion 2301 and the first connecting structure 222, thereby improving the reliability of the connection.

[0135] In addition, continue as Figure 22 As shown, the base 21 may include a receiving structure 211 and a second connecting structure 212. The receiving structure 211 can bypass the opening 06 (e.g., Figure 6 The inner ring (as shown) is arranged in a manner that forms a circle like... Figure 24 The cavity 210 shown above is used to house the sealing ring assembly 23, the lifting assembly 22, and the camera module 10. Furthermore, continuing as... Figure 22 As shown, the second connecting structure 212 of the base 21 is located at the end of the receiving structure 211 facing the light-incident surface S0 of the camera module 10. Figure 24 As shown, the second connecting structure 212 is arranged around the circumference of the receiving structure 211, and the second connecting structure 212 can be connected to the receiving structure 211. The connection method of the receiving structure 211 and the second connecting structure 212 is the same as the connection method of the lifting cover 221 and the first connecting structure 222, and will not be described again here.

[0136] On this basis, continue as Figure 22As shown, the sealing ring assembly 23 further includes a second metal ring 232, which is located on the surface of the second connecting structure 212 facing the light-incident surface S0 of the camera module 10 (i.e., the upper surface of the second connecting structure 212). The second metal ring 232 is connected to the second connecting structure 212. Furthermore, the second metal ring 232 may include a first surface S1 facing the second connecting structure 212 (i.e., the lower surface of the second metal ring 232) and a second surface S2 facing away from the second connecting structure 212 (i.e., the upper surface of the second metal ring 232). One end of the second annular portion 2302, facing away from the third annular portion 2303, wraps around a portion of the first surface S1 and a portion of the second surface S2, as well as the inner annular surface of the second metal ring 232.

[0137] Similarly, the second metal ring 232 can be a metal ring made of steel sheet. The good flatness of the surface of the second metal ring 232 can improve the reliability of the connection between the second metal ring 232 and the second connecting structure 212 and the second annular portion 2302. Furthermore, the second metal ring 232 can be connected to the second metal ring 232 by partially wrapping it, allowing the portion of the second surface S2 of the second metal ring 232 not covered by the second annular portion 2302 to connect with other components. This improves the space utilization of the second surface S2 of the second metal ring 232 and facilitates miniaturization design of the product.

[0138] The following examples illustrate other components connected to the second surface S2 of the second metal ring 232. For instance, the aforementioned electronic device 01 may include, for example... Figure 25 The decorative cover 50 shown can be fastened to the lens cover assembly 20, and the device 50 can be arranged around the lifting component 22 in the lens cover assembly 20. In this way, the decorative cover 50 can decorate the outer surface of the lens cover assembly 20, meeting the relevant requirements of the appearance design. Based on this, as... Figure 26 (for the following) Figure 25 As shown in the cross-sectional view obtained by cutting along the dashed lines A3-A4, the decorative cover 50 can be connected to the part of the second surface S2 of the second metal ring 232 that is not covered by the second annular portion 2302, thereby improving the space utilization of the second surface S2.

[0139] The above example illustrates the connection between the second annular portion 2302 and the second metal ring 232, using the example of the second annular portion 2302 covering a portion of the second surface S2 of the second metal ring 232. In other embodiments of this application, such as Figure 27 (for Figure 9As shown in another enlarged view at point B in the figure, when the base 21 includes a receiving structure 211 and a second connecting structure 212, the second metal ring 232 can be located between the second annular portion 2302 and the second connecting structure 212. A portion of the second annular portion 2302 covers the surface of the second metal ring 232 facing away from the second connecting structure 212 (i.e., the upper surface of the second metal ring 232), and the second metal ring 232 is connected to the second connecting structure 212 and the second annular portion 2302. Similarly, the upper and lower surfaces of the second metal ring 232 can have good flatness, which can improve the reliability of the connection between the second metal ring 232 and the second connecting structure 212 and the second annular portion 2302.

[0140] The above description is merely a specific embodiment of this application, but the scope of protection of this application is not limited thereto. Any changes or substitutions within the technical scope disclosed in this application should be included within the scope of protection of this application. Therefore, the scope of protection of this application should be determined by the scope of the claims.
