[0001] This application claims priority to the Chinese patent application filed with the China Patent Office on December 18, 2023, with application number 202311750719.2 and invention name “A housing assembly and electronic device”, the entire contents of which are incorporated by reference into this application. Technical Field

[0002] The present invention relates to the technical field of electronic equipment, and in particular to a housing assembly and electronic equipment. Background Art

[0003] Mobile phone camera trims are typically mounted on the back of a phone to enhance the camera's appearance and provide additional functionality, such as waterproofing.

[0004] However, current mobile phone camera trims occupy a significant amount of internal space, making it impossible to directly accommodate larger cameras within the phone. To address this issue, the phone's thickness needs to be increased to accommodate the larger camera's mounting space. However, this results in a thicker phone, failing to meet user demand for ultra-thin phones.

DETAILED DESCRIPTION

[0044] The following describes embodiments of the present invention in detail, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, and are not to be construed as limiting the present invention.

[0045] In related technologies, the camera assembly on the back of a mobile phone typically includes multiple cameras, such as a wide-angle camera and a telephoto camera. To balance aesthetics, waterproofing, and dustproofing, a hole is opened in the back of the phone where the camera is located, and internal and external decorative parts are installed. The internal decorative parts are placed inside the phone, while the external decorative parts are placed outside. The internal and external decorative parts are each sealed against the back of the phone. The internal decorative ring is located below the orthographic projection of the external decorative part on the back of the phone, that is, directly below the outer decorative ring, occupying a large space directly below the outer decorative ring.

[0046] As users demand higher-quality camera footage, the number of cameras installed in mobile phones is increasing, and their size is also increasing (the length of the camera is increasing, with the length of the camera perpendicular to the thickness of the camera, and the thickness of the camera is the same as the thickness of the phone). This also increases the space required for these cameras. Currently, due to the limited internal installation space of the phone, large cameras conflict with the space occupied by the inner decorative ring. Currently, the outer decorative ring is usually positioned upward, increasing the thickness of the phone to increase the installation space for the camera inside the phone. The resulting increase in phone thickness deviates from user demand for ultra-thin phones.

[0047] To this end, the present invention provides a housing assembly and an electronic device.

[0048] Specifically, a housing assembly and an electronic device according to an embodiment of the present invention are described below with reference to the accompanying drawings.

[0049] Figure 1 is a schematic structural diagram of a housing assembly according to one embodiment of the present invention, Figure 2 is a cross-sectional view taken along line AA of Figure 1 , and Figure 3 is an enlarged view of line A in Figure 2 . It should be noted that the housing assembly of the present invention can be applied to conventional electronic devices with camera functions, such as digital cameras, smartphones, tablet computers, video cameras, televisions, laptop computers, webcams, driving recorders, smart wearable devices (smart watches, smart glasses, etc.), point of sales (POS), augmented reality (AR), and virtual reality (VR) devices.

[0050] In implementation, when the shell assembly is used in the back camera of an electronic device, the shell assembly may be a rear shell assembly of the electronic device. It is easy to understand that when the shell assembly is used in the front camera of an electronic device, the shell assembly may be a front shell assembly of the electronic device. In the embodiment of this scheme, only the shell assembly may be the rear shell assembly of the electronic device as an example. It can be understood that when the rear shell assembly is applied to an electronic device, the electronic device also includes a front shell assembly adapted to the rear shell assembly, and the front shell assembly and the rear shell assembly can be buckled together. The outer side of the shell assembly in this embodiment can be understood as the side away from the interior of the electronic device. Similarly, the inner side of the shell assembly can be understood as the side facing the interior of the electronic device.

[0051] As shown in FIG. 1 , FIG. 2 and FIG. 3 , the housing assembly includes an outer decorative component 10 , an inner decorative component 20 , a first sealant layer 30 , an outer shell 40 and a second sealant layer 50 .

[0052] The outer trim 10 is provided with at least one camera window 11. The inner trim 20 includes an inner sealing ring 21, a retaining ring 22, and an outer sealing ring 23. The inner sealing ring 21 is laminated to the inner periphery of the outer trim 10. The retaining ring 22 bends and extends from the outer edge of the inner sealing ring 21 toward the inner side of the outer trim 10 and connects to the outer sealing ring 23. The outer sealing ring 23, the retaining ring 22, and the inner side of the outer edge of the outer trim 10 form an outwardly opening annular groove. A first sealant layer 30 is sealingly connected between the inner sealing ring 21 and the inner periphery of the outer trim 10. The outer housing 40 has a through hole. The annular inner wall 41 of the through hole of the outer housing 40 includes an inner annular portion 411 near the center of the through hole and an outer annular portion 412, which is connected to the inner annular portion 411 and is located away from the center of the through hole. The inner annular portion 411 is embedded in the annular groove, while the outer annular portion 412 is located outside the annular groove. The second sealant layer 50 is sealed between the annular inner wall 41 of the through-hole and the outer sealing ring 23. The outer sealing ring 23 includes a first outer sealing interval ring 231, which extends to the exposed annular portion 412 of the housing 40. The second sealant layer 50 includes a first interval rubber layer 51, which is sealed between the first outer sealing interval ring 231 and the exposed annular portion 412 of the outer sealing ring 23.

[0053] In the technical solution provided by the embodiment of this solution, the shell assembly includes an outer decorative part 10, an inner decorative part 20, a first sealant layer 30, an outer shell 40 and a second sealant layer 50. The outer decorative part 10 is provided with at least one camera window 11, which can be used for the camera to capture images.

[0054] The interior trim 20 includes an inner sealing ring 21, a retaining ring 22, and an outer sealing ring 23. The inner sealing ring 21 is laminated to the inner periphery of the outer trim 10. The retaining ring 22 bends and extends from the outer edge of the inner sealing ring 21 toward the inner side of the outer trim 10 and connects to the outer sealing ring 23. The outer sealing ring 23, retaining ring 22, and the inner side of the outer edge of the outer trim 10 form an outwardly opening annular groove. A first sealant layer 30 is hermetically connected between the inner sealing ring 21 and the inner periphery of the outer trim 10, forming a seal outward of the housing 40 to prevent moisture from passing between the interior trim 20 and the outer trim 10.

[0055] The housing 40 has a through hole. The annular inner wall 41 of the through hole includes an inset annular portion 411 near the center of the through hole and an exposed annular portion 412, which is connected to the inset annular portion 411 and further away from the center of the through hole. The inset annular portion 411 is embedded in the annular groove, while the exposed annular portion 412 is located outside the annular groove. A second sealant layer 50 is sealed between the annular inner wall 41 of the through hole and the outer sealing ring 23, preventing moisture from passing between the interior decorative component 20 and the housing 40.

[0056] Therefore, the first sealant layer 30 and the second sealant layer 50 can achieve a sealed connection between the outer decorative component 10 , the inner decorative component 20 and the housing 40 , and can be applied to electronic devices with waterproof and dustproof requirements.

[0057] In this solution, by extending the first outer sealing interval ring 231 of the inner decorative component 20 to the exposed annular portion 412 of the outer shell 40, the first interval adhesive layer 51 of the second sealing adhesive layer 50 is sealed between the first outer sealing interval ring 231 of the outer ring sealing ring 23 and the exposed annular portion 412. Compared to the aforementioned related art, due to the extension of the first outer sealing interval ring 231 of the inner decorative component 20 to the exposed annular portion 412 of the outer shell 40, the inner decorative ring is "shifted" outward from the outer decorative component below the orthographic projection area of ​​the phone back shell, providing "expanded installation space" for large-sized cameras (e.g., cameras with increased length), thus meeting the large-sized camera installation requirements of ultra-thin waterproof phones.

[0058] The outer decorative ring is mounted on the outer surface of the housing 40, exposed on the outside of the housing 40, and serves a decorative purpose. It is typically made of metal, but is not limited to other materials such as plastic. As shown in Figures 2 and 3 , the outer surface of the outer decorative member 10 may be provided with a window bezel. The housing assembly also includes a window cover 80 . At least one camera window 11 is positioned at the bottom of the window bezel. The window cover 80 is positioned within the window bezel, sealing the at least one camera window 11.

[0059] As shown in Figures 1, 2, and 3, in this embodiment of the present invention, the first sealant layer 30 seals the outer trim 10 and inner trim 20, the second sealant layer 50 seals the inner trim 20 and the annular inner wall 41 of the through-hole of the housing 40, and the window cover 80 seals the at least one camera window 11. Consequently, at the through-hole of the housing assembly, the outer trim 10, the inner trim 20, and the housing 40 form a sealed whole, meeting the waterproof requirements of the electronic device.

[0060] Figure 4 is a front structural diagram of the combination of the inner decorative part 20 and the outer decorative part 10 of the shell component according to an embodiment of the present invention, and Figure 5 is an exploded structural diagram of the assembly structure of the inner decorative part 20 and the waterproof breathable layer 70 of the shell component according to an embodiment of the present invention. As shown in Figures 4 and 5, it is easy to understand that in the embodiment of sealing the camera window 11, a window sealant layer 81 can be used to cover the outer periphery of the camera window 11, and the window cover 80 can be sealed to the bottom of the window groove of the outer decorative part 10, so that the IPX8 waterproof function of the electronic device can be achieved.

[0061] The window cover 80 can be a transparent glass cover or plastic cover, so that light outside the shell assembly can enter the camera at the camera window 11 of the outer decorative component 10 through the window cover 80, making it easier for the camera to collect external image information.

[0062] The number of camera windows 11 can be determined based on the number of cameras actually required. That is, when the housing assembly is adapted for an electronic device with one camera, the number of camera windows 11 is one. When the housing assembly is adapted for an electronic device with two cameras, the number of camera windows 11 is two. When the housing assembly is adapted for an electronic device with three cameras, the number of camera windows 11 is three.

[0063] The shape of the outer decorative component 10 can be set according to the layout positions of multiple cameras in the actual product. Specifically, it can be circular, triangular, rectangular, pentagonal, etc., which is not limited in the embodiments of the present invention.

[0064] Normally, the inner decoration part 20 completely falls within the positive projection of the outer decoration part 10 on the outer shell 40, that is, the inner decoration part 20 will occupy a large amount of space directly below the outer decoration part 10. Directly below the outer decoration part 10 is the installation space for the camera, which makes it difficult to directly assemble a camera of a larger size. Figure 6 is a schematic diagram of the disassembled structure of a shell assembly according to an embodiment of the present invention. As shown in Figures 3 and 6, in this solution, the first outer sealing interval ring 231, the retaining ring 22 and the inner side of the outer edge of the outer decoration part 10 form a first interval groove of an annular embedding groove. The embedded annular part 411 includes a first interval inner wall 413, and the first interval inner wall 413 is embedded in the first interval groove. In the first interval groove, the distance between the outer surface of the retaining ring 22 and the edge of the outer decoration part 10 is 0.5mm to 2mm.

[0065] Because the first outer sealing zone ring 231 of the interior trim 20 extends to the exposed annular portion 412 of the outer shell 40 and is sealed therewith, the first outer sealing zone of the interior trim 20 can be expanded outward, allowing the retaining ring 22 to "move" toward the edge of the outer trim 10. This reduces the space occupied by the interior trim 20 directly below the outer trim 10 and provides space for a larger camera. Specifically, in the first zone groove, the retaining ring 22 "shifts" outward to the edge of the outer trim 10, with a distance of 0.5mm to 2mm from the edge of the outer trim 10, providing more space for camera installation.

[0066] As shown in Figures 3 and 6, the exposed annular portion 412 extends toward the center of the through hole and forms a curved convex ring away from the inner side of the housing 40. The curved convex ring is an exposed smooth curved surface structure, and users can get a smoother touch when using the electronic device.

[0067] As shown in Figure 3, because the exposed annular portion 412 is curved, the first adhesive layer 51 includes a double-sided adhesive layer 511 that matches the curved convex ring shape and has a curved surface. The first outer sealing interval ring 231 matches the curved convex ring shape and has a curved outer sealing interval ring. The double-sided adhesive layer 511 can be waterproof and foam-resistant, facilitating a secure seal between the first outer sealing interval ring 231 and the exposed annular portion 412. In practice, tolerances exist in the manufacturing dimensions of the curved double-sided adhesive layer 511. When the curved exposed annular portion 412 is aligned, the double-sided adhesive layer 511 may not fully contact and seal with the retaining ring 22 of the interior decorative component 20. If the double-sided adhesive layer 511 is manufactured larger, due to the tolerance, the double-sided adhesive layer 511 in some parts of the housing assembly may exceed the required length. The double-sided adhesive layer 511 that exceeds the length to cover the retaining ring 22 may warp, affecting the insertion of the embedded annular portion 411 of the housing 40. If the double-sided adhesive layer 511 is made smaller, so that the double-sided adhesive layer 511 of some housing components completely fits the retaining ring 22, due to tolerances, the double-sided adhesive layer 511 of other housing components will not meet the required length and will not reach the retaining ring 22. As a result, a gap 512 is likely to exist between the double-sided adhesive layer 511 and the retaining ring 22. External moisture may enter the gap 512 between the outer edge of the outer decorative component 10 and the outer shell 40 through the gap 512 and gradually penetrate the double-sided adhesive layer 511, causing water to enter the electronic device.

[0068] In this embodiment, the first interval adhesive layer 51 also includes a dotted adhesive layer, which fills the gap 512 between the double-sided adhesive layer 511 and the retaining ring 22. That is, during assembly, the gap 512 between the double-sided adhesive layer 511 and the retaining ring 22 can be filled by injecting fluid adhesive. The use of a waterproof fluid adhesive facilitates the complete filling of gaps 512 of varying sizes within different housing assemblies. Once the injected fluid adhesive solidifies, the dotted adhesive layer is formed, effectively achieving a waterproof seal within the gap 512.

[0069] As shown in Figures 3 and 6, to ensure that the embedded annular portion 411 of the housing 40 is securely embedded within the annular groove, the embedded annular portion 411 extends toward the center of the through-hole and forms a flat convex ring, which connects the flat convex ring and the curved convex ring. In this embodiment, the embedded annular portion 411 is a flat convex ring, which can be securely embedded within the annular groove, thereby increasing the service life of the housing assembly. Furthermore, because the first section adhesive layer 51 in this embodiment includes a dotted adhesive layer and a double-sided adhesive layer 511, it can effectively seal the curved connection between the flat convex ring and the curved convex ring, effectively reducing the problem of the flat convex ring "lifting" out of the annular groove.

[0070] Typically, the interior decoration 20 can be made of metal material. However, the use of the interior decoration 20 made of metal material will make the overall weight of the shell assembly larger. In this solution, in order to reduce the weight of the shell assembly, the interior decoration 20 can be made of plastic material to reduce the weight of the shell assembly. During preparation, the interior decoration 20 can be prepared by injection molding to prepare an integrally formed injection molded part. The inventors found that since the interior decoration 20 made of metal material and the interior decoration 20 made of plastic material have different processing techniques, the processing tolerances of the two are quite different (the manufacturing tolerance of the interior decoration 20 of the injection molded part is greater than the manufacturing tolerance of the interior decoration 20 of the metal part). Therefore, after using the second sealant layer 50 that fits the metal interior decoration to directly bond the injection molded interior decoration 20, the adhesive effect of the second sealant layer 50 on the plastic interior decoration 20 is reduced. In this solution, the inventors realized the above-mentioned problem and increased the thickness of the second sealant layer 50 to 0.35±0.05mm, for example, 0.30mm, 0.31mm, 0.32mm, 0.33mm, 0.34mm, 0.35mm, 0.36mm, 0.37mm, 0.38mm, 0.39mm, 0.40mm, so that the thickness of the second sealant layer 50 set in this embodiment can overcome the problem of reduced adhesion effect of the second sealant layer 50 caused by the preparation tolerance after the material of the interior decorative part 20 is replaced with plastic, and can achieve good sealing between the first outer sealing interval ring 231 and the exposed annular portion 412.

[0071] As shown in Figure 3, the shell 40 of the shell assembly has a variety of materials. Among them, the shell 40 made of PU material has many advantages such as durability, softness, and anti-fingerprint, and can be applied to this embodiment. The shell 40 includes: a stacked base layer 40a and a polyurethane layer 40b, the polyurethane layer 40b is located on the outer surface of the shell 40, and the base layer 40a is located on the inner surface of the shell 40. The base layer 40a and the polyurethane layer 40b can be prepared as the shell 40 of the shell assembly by a hot pressing process. By using the second sealant layer 50 with a thickness of 0.35±0.05mm in the above embodiment, a good sealing and bonding between the shell 40 of PU material (formed by hot pressing of the stacked base layer 40a and the polyurethane layer 40b) and the first outer sealing interval ring 231 in this embodiment can be achieved.

[0072] Figure 7 is a schematic diagram of the exploded structure of some components in a shell assembly according to an embodiment of the present invention. As shown in Figure 7, the first outer sealing interval ring 231, the exposed annular portion 412 and the double-sided adhesive layer 511 are annular structures. The preparation tolerance of the double-sided adhesive layer 511 is large, and the curvature of the prepared double-sided adhesive layer 511 is difficult to completely match the size of the first outer sealing interval ring 231 and the exposed annular portion 412. In this solution, at least one edge of the inner ring sealing ring 21 and the outer ring sealing ring 23 of the double-sided adhesive layer 511 is provided with multiple notches 513 at intervals, so that the curvature of the double-sided adhesive layer 511 can be easily adjusted to achieve matching of the curvature of the double-sided adhesive layer 511 with the curvature size of the first outer sealing interval ring 231 and the exposed annular portion 412 for good sealing and fitting.

[0073] Figure 8 is an enlarged view of point B in Figure 2 , Figure 9 is a schematic diagram of the structure of the housing assembly interior decorative component 20 from a first perspective according to one embodiment of the present invention, and Figure 10 is a schematic diagram of the structure of the housing assembly interior decorative component 20 from a second perspective according to one embodiment of the present invention. As shown in Figures 8 , 9 , and 10 , in specific implementations, a large-sized camera is installed within an electronic device, where the required space may only be in a specific direction. Therefore, in this embodiment, the first outer sealing interval ring 231 is not limited to a complete outer ring sealing ring 23; it may be a partial outer ring sealing ring 23. In implementations, the outer ring sealing ring 23 also includes a second outer sealing interval ring 232, which extends to the inner annular portion 411. The second sealant layer 50 includes a second interval adhesive layer 52, which is sealed between the second outer sealing interval ring 232 and the inner annular portion 411. The second outer sealing interval ring 232 is located below the positive projection of the outer decorative part 10 on the outer shell 40, so that the second interval adhesive layer 52 can be clamped between the outer decorative part 10 and the inner decorative part 20. After the inner decorative part 20 and the outer decorative part 10 are relatively fastened, the second interval adhesive layer 52 can form a good bonding effect on the inner decorative part 20 and the outer shell 40.

[0074] As shown in Figure 8 , because the second outer sealing zone ring 232 is located below the orthographic projection of the outer decorative component 10 on the housing 40, a deeper annular groove can be formed, allowing the housing 40 to be embedded deeper. In practice, the second outer sealing zone ring 232, the retaining ring 22, and the inner side of the outer edge of the outer decorative component 10 form a second zone groove of the annular groove. The inner ring portion 411 includes a second zone inner wall 414, which is embedded in the second zone groove. In the second zone groove, the distance between the outer surface of the retaining ring 22 and the edge of the outer decorative component 10 is between 2.5 mm and 4 mm. Compared to the first zone groove, the retaining ring 22 in the second zone groove is closer to the center of the through-hole of the housing 40. As a result, the second zone groove is deeper, the inner ring portion 411 of the housing 40 is longer, and the connection is more stable. The second zone inner wall 414 embedded in the second zone groove is less likely to dislodge and warp. That is, in practice, the interior decorative component 20 adopts a method of partially (first outer sealing interval ring 231) "expanding outward" and partially (second outer sealing interval ring 232) "not expanding outward", which can take into account the space installation requirements of large-size cameras and meet the stability requirements of the shell component shell 40.

[0075] The first sealant layer may be a sealant layer formed by curing a fluid glue.

[0076] As shown in Figure 7, to improve assembly efficiency, the first and second interval adhesive layers 51 and 52 are staggered and joined end-to-end to form an annular second sealing adhesive layer 50. The first and second outer sealing interval rings 231 and 232 are joined end-to-end to form an annular outer sealing ring 23. The annular second sealing adhesive layer 50 can be easily attached to the annular outer sealing ring 23.

[0077] As shown in Figures 7 and 8 , to further enhance the connection stability between the outer shell 40 and the inner and outer decorative rings, the housing assembly further includes a fixing adhesive layer 60. The fixing adhesive layer 60 connects the inner wall 414 of the second section to the outer decorative member 10. An adhesive layer groove may also be provided on the inner side of the outer decorative member 10, within which the fixing adhesive layer 60 is disposed.

[0078] As shown in Figure 3, at the position of the inner wall 413 of the first interval of the annular part 411 embedded in the shell 40, the inner wall 413 of the first interval can directly contact the outer decorative part 10, and no fixed adhesive layer 60 is provided, so that the bottom of the retaining ring 22 can obtain a certain amount of "rise" (close to the outer decorative ring), and a certain rising space can be provided for the camera at the bottom of the outer decorative ring.

[0079] In an embodiment of the present invention, when a large camera is installed, the interior decorative component 20 can utilize a flat inner ring seal 21 and a curved first outer sealing interval ring 231. The second sealing adhesive layer 50 can utilize a flat first sealing adhesive layer 30 and a curved first interval adhesive layer 51 in combination with a dotted adhesive layer to achieve sealing at the opening of the outer shell 40. When a small camera is installed, the interior decorative component 20 can utilize a flat inner ring seal 21 and a flat second outer sealing interval ring 232. The second sealing adhesive layer 50 can utilize a flat first sealing adhesive layer 30 and a flat second interval adhesive layer 52 in combination with a dotted adhesive layer to achieve sealing at the opening of the outer shell 40. By using this embodiment, a larger installation space can be provided for the camera without expanding the outer decorative component 10, thereby maintaining the smaller size of the outer decorative component 10.

[0080] The housing assembly in this embodiment can be used in waterproof electronic devices and can achieve an IPX8 protection level. In IPX8, X represents the dustproof level of the electronic device, and 8 represents the waterproof level of the electronic device. When the electronic device is immersed in water with its top 1.5m to 30m away from the water surface for 30 consecutive minutes, the electronic device can operate normally without leaking.

[0081] While achieving the IPX8 rating for electronic devices, the electronic device must also have a high airtightness. However, when the housing 40 of the electronic device is pressurized, the internal pressure can fluctuate significantly. Within the electronic device, electronic components (such as speakers) can easily malfunction when subjected to significant pressure fluctuations. As shown in Figures 4 and 5 , in this embodiment, to overcome these issues, the housing assembly further includes a waterproof and breathable layer 70 and a window cover 80.

[0082] The outer surface of the exterior decorative component 10 is provided with a window groove, at the bottom of which is provided at least one camera window 11 and a through-going vent 12. A window cover 80 is positioned within the window groove and covers the at least one camera window 11. A breathable gap 512 is defined between the outer edge of the window cover 80 and the outer edge of the window groove. The bottom of the window groove is also provided with at least one breathable channel 13 connecting the vent 12 and the breathable gap 512. A waterproof breathable layer 70 covers the vent 12 and can be specifically bonded to the vent 12 using an annular adhesive layer 71 that matches the shape of the vent 12. When this housing assembly is used in an electronic device, when the housing 40 is subjected to pressure, the waterproof breathable membrane connects the inside and outside of the electronic device housing 40, thereby reducing the pressure differential between the inside and outside of the electronic device housing 40. Furthermore, the waterproof breathable membrane prevents water from entering the housing 40, achieving waterproof and dustproof properties.

[0083] As will be readily understood, the number and routing of the ventilation channels 13 can be determined based on the specific structural layout of the camera window 11. Specifically, there can be at least two ventilation channels 13, each extending in different directions from the vent 12 and connected to the ventilation gap 512 on the periphery of the window cover 80. If one ventilation channel 13 is blocked, ventilation can be achieved through the remaining ventilation channels 13.

[0084] As shown in Figure 10, in practice, the interior trim 20 also includes at least one support member 24 extending toward the interior of the outer shell 40. When the housing assembly is used in an electronic device, the electronic device will have a motherboard installed within. The support member 24 of the interior trim 20 can be supported by the motherboard, providing stable support for the interior trim 20. Specifically, two support members 24 can be provided, one at a first position on the inner sealing ring 21 near the first outer sealing interval ring 231 and the other at a second position on the inner sealing ring 21 near the second outer sealing interval ring 232. Because the outer shell is made of a relatively soft PU material, the support member 24 in the first position provides relatively stable support for the PU outer shell.

[0085] Figure 11 is a schematic diagram of the back structure of the combination of the inner decorative part 20 and the outer decorative part 10 of the shell assembly according to an embodiment of the present invention, and Figure 12 is a schematic diagram of the cross-sectional structure of BB in Figure 11. As shown in Figures 11 and 12, in realizing the fastening connection between the outer decorative part 10 and the inner decorative part 20, a fastening screw connection can be used. The shell assembly also includes: at least one locking screw 90, which is inserted into the through hole of the inner ring sealing ring 21 of the inner decorative part 20 and locked with the internal thread of the outer decorative part 10.

[0086] FIG13 is a schematic diagram of a partial internal structure of an electronic device according to an embodiment of the present invention. As shown in FIG13 and FIG14 , FIG14 is a schematic diagram of a partial cross-sectional structure of the position of the first camera 101 of the electronic device according to an embodiment of the present invention.

[0087] An electronic device according to another embodiment of the present invention includes: the housing assembly of the above embodiment and at least one camera, wherein the image acquisition end of each camera faces the corresponding camera window 11 .

[0088] Specifically, the at least one camera includes a first camera 101, and the at least one camera window 11 includes a first window 111. The image acquisition end of the first camera 101 faces the first window 111. The first corner of the first camera 101 is located at a corner of the interior trim 20 near the first outer sealing interval ring 231. The first camera 101 is a periscope camera.

[0089] During implementation, avoidance space is reserved between the first corner of the first camera 101 and the inner sealing ring 21 and the retaining ring 22 of the inner decoration part 20, respectively, to reduce the risk of the inner decoration part 20 and the first camera 101 touching each other after the outer shell is compressed and deformed.

[0090] Specifically, at least one camera includes a second camera 102 and a third camera 103, and at least one camera window 11 includes a second window 112 and a third window 113. The image acquisition end of the second camera 102 faces the second window 112, and the image acquisition end of the third camera 103 faces the third window 113.

[0091] The first camera 101 is a rectangular structure. The size of the second camera 102 and the size of the third camera 103 are respectively smaller than the size of the first camera 101. The second camera 102 and the third camera 103 are located on one side of the width direction of the first camera 101. The second camera 102 and the third camera 103 are arranged in the length direction of the first camera 101.

[0092] In the interior trim 20, the outer sealing ring 23 includes a second outer sealing interval ring 232, which extends to the inner annular portion 411 of the housing 40. The second sealant layer 50 includes a second interval rubber layer 52, which is sealed between the second outer sealing interval ring 232 and the inner annular portion 411. The first corner of the second camera 102 is located at a corner of the interior trim 20 near the second outer sealing interval.

[0093] By adopting the above-mentioned camera layout method, the length of the curved first interval glue layer 51 can be minimized, so that its proportion in the length of the second sealing glue layer 50 is less than or equal to 40%. It is easy to understand that reducing the proportion of the length of the curved first interval glue layer 51 in the second sealing glue layer 50 can improve the stability of the second sealing glue layer 50 sealed to the annular inner wall and outer ring sealing ring of the through hole.

[0094] During implementation, avoidance space is reserved at the first corner of the second camera 102 and between the inner sealing ring 21 and the retaining ring 22 of the inner decorative part 20, respectively, to reduce the risk of the inner decorative part 20 and the second camera 102 touching each other after the outer shell is compressed and deformed.

[0095] It should be noted that in the examples and description of this patent, relational terms such as first and second, etc. are used only to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device that includes a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device. In the absence of further restrictions, an element defined by the sentence "including a" does not exclude the presence of other identical elements in the process, method, article or device that includes the element.

[0096] Although the present application has been shown and described with reference to certain preferred embodiments thereof, it will be understood by those skilled in the art that various changes in form and details may be made therein without departing from the spirit and scope of the application.
