[0001] This application relates to the field of terminals, and in particular to an electronic device and its housing decoration parts and housing. Background Technology

[0002] With the development of optical imaging technology, the performance of camera modules used in electronic devices is becoming increasingly powerful, and their size is also increasing. To reduce the overall thickness of electronic devices, mounting holes of a size adapted to the camera module are usually made in the electronic device's casing, allowing the camera module to protrude from the casing. Decorative parts are then placed at the opening locations on the casing to protect the camera module, and these decorative parts are sealed to the casing to maintain the electronic device's airtightness when it is mounted.

[0003] In existing products, decorative parts are sealed and attached to the outer shell by means of gluing, welding, etc. When replacing decorative parts with different appearances or functions, the outer shell must be disassembled first, the original decorative part and the outer shell seal connection must be broken, and then the decorative part to be replaced must be sealed and attached to the outer shell. Thus, the process of replacing decorative parts is complicated and affects the user's experience of replacing decorative parts. Summary of the Invention

[0004] In view of this, the present application provides an electronic device and its housing decoration parts and housing. By designing the decoration parts as detachably connected inner and outer decoration parts, and sealing the inner decoration parts with the electronic device housing, and detachably connecting the outer decoration parts with the inner decoration parts, the user's need to replace the decoration parts can be met, while ensuring the sealing performance of the electronic device.

[0005] The first aspect of this application provides a decorative element applied to the housing of an electronic device. The decorative element includes: an inner decorative element, which includes a sealing portion for sealing and adhering to the inner side of the housing, such that the outer portion of the inner decorative element is sealed relative to the housing; and an outer decorative element disposed on the outer side of the housing and detachably connected to the inner decorative element.

[0006] In other words, the decorative component in this embodiment includes an inner decorative component and an outer decorative component. The inner decorative component is disposed on the inner side of the housing and is sealed and fitted to the housing of the electronic device, thereby ensuring the sealing performance of the electronic device when the housing is installed on the electronic device. In this way, by replacing the outer decorative component, the user's needs for changing decorative components with different appearances and / or functions can be met, improving the user's experience in changing decorative components. At the same time, since the inner decorative component and the housing are sealed, the sealing performance of the electronic device can be guaranteed.

[0007] In a first possible implementation of the first aspect described above, the detachable connection is a screw-in connection, the inner trim includes an external thread, the outer trim includes an internal thread, and the outer trim and the inner trim are screwed together by the external thread and the internal thread.

[0008] In this embodiment, a detachable connection between the outer and inner trim parts is achieved by providing external threads on the inner trim part and internal threads on the outer trim part that are compatible with the internal threads. This allows for the removal or installation of the outer trim part by loosening or tightening the threads, facilitating its replacement.

[0009] In a second possible implementation of the first aspect described above, the detachable connection is a snap-fit, and the trim piece further includes at least one pair of snaps and slots, wherein the snaps are rotated to engage with the slots to restrict the movement of the outer trim piece relative to the inner trim piece in a direction perpendicular to the housing; and the snaps are disposed on the inner trim piece or the outer trim piece, and the slots are disposed on the outer trim piece or the inner trim piece.

[0010] In other words, in this embodiment, the detachable connection between the outer and inner trim pieces is a snap-fit, and the snap-fit ​​groove restricts the movement of the outer trim piece relative to the inner trim piece in a direction perpendicular to the outer shell (i.e., axial direction). The snap-fit ​​can be engaged or disengaged from the groove by rotating the outer trim piece, thereby enabling the removal and replacement of the outer trim piece.

[0011] In the third possible implementation combining the second possible implementation of the first aspect above, the decorative part includes three pairs of buckles and slots; and the buckles are evenly distributed circumferentially on the outer decorative part, and the slots are evenly distributed circumferentially on the inner decorative part.

[0012] In a fourth possible implementation combining the third possible implementation of the first aspect described above, the decorative element also includes a limiting mechanism for restricting the circumferential rotation of the outer decorative element relative to the inner decorative element.

[0013] In this embodiment, the slot and the buckle can restrict the axial movement of the outer trim piece relative to the inner trim piece, and the addition of a limiting mechanism can restrict the circumferential rotation of the outer trim piece relative to the inner trim piece, thereby stabilizing the connection between the outer trim piece and the inner trim piece.

[0014] In the fifth possible implementation of the fourth possible implementation of the first aspect described above, the limiting mechanism includes at least a pair of first protrusions and second protrusions with opposite protrusion directions, wherein at least one of the first protrusions and second protrusions is an elastic protrusion; the first protrusions and second protrusions are respectively disposed on the inner decorative part and the outer decorative part; and when the buckle enters the slot, the first protrusions and second protrusions overcome the elastic force to cause the adjacent sequence of the first protrusions and second protrusions to be misaligned to achieve rotational positioning.

[0015] In this embodiment, before the buckle is inserted into the slot, the first protrusion is located to the left of the second protrusion. When the buckle is fully inserted into the slot, the first protrusion is located to the right of the second protrusion, and the right side of the second protrusion abuts against the left side of the first protrusion. This enables circumferential rotational positioning and restricts the circumferential rotation of the outer decorative part relative to the inner decorative part, thereby preventing the outer decorative part from accidentally falling off.

[0016] In the sixth possible implementation of the fifth possible implementation of the first aspect mentioned above, the second protrusion is an elastic protrusion, and there are three pairs of first and second protrusions; and the first protrusions are circumferentially distributed on the inner trim piece, and the second protrusions are circumferentially distributed on the outer trim piece.

[0017] In the seventh possible implementation of the sixth possible implementation of the first aspect mentioned above, the first protrusion protrudes radially outward.

[0018] In the eighth possible implementation of the fourth possible implementation of the first aspect described above, the limiting mechanism includes a resilient pin, a lever, and a limiting hole opened in the interior trim, wherein the resilient pin and the lever are disposed in the exterior trim; when the lever is in the locked position, the resilient pin overcomes the elastic force and inserts into the limiting hole to restrict the circumferential rotation of the exterior trim relative to the interior trim; when the lever is in the unlocked position, the elastic force of the resilient pin is released, causing the resilient pin to pop out of the limiting hole so that the exterior trim can rotate circumferentially relative to the interior trim.

[0019] In other words, in this embodiment of the application, by opening a limiting hole on the inner trim piece and setting an elastic pin on the outer trim piece, after the buckle is fully engaged in the slot, the elastic pin is aligned with the limiting hole, and the elastic pin can be inserted into or removed from the limiting hole, thereby locking or unlocking the circumferential rotation of the outer trim piece relative to the inner trim piece, thereby preventing the outer trim piece from accidentally falling off.

[0020] In the ninth possible implementation of the eighth possible implementation of the first aspect described above, the limiting mechanism further includes a cavity formed in the outer decorative part and a guide hole formed in the cavity wall of the cavity; the elastic pin includes a pin rod facing the guide hole, at least one spring with the elastic force direction in the same direction as the extension of the pin rod, and a pin wall; wherein, one end of the at least one spring abuts against the cavity wall of the cavity, and the other end abuts against the pin wall; the guide hole is oriented radially inward, so that the pin rod can be inserted into or ejected from the limiting hole through the guide hole.

[0021] In a tenth possible implementation in conjunction with the ninth possible implementation of the first aspect described above, the resilient pin further includes spring mounting rods in the same number as at least one spring; the spring mounting rods are disposed on the pin wall and extend in the same direction as the pin; and at least one spring is fitted onto the spring mounting rod.

[0022] In the eleventh possible implementation of the tenth possible implementation of the first aspect mentioned above, the lever is an arc-shaped lever, and the lever also includes a guide surface disposed on the concave surface of the lever for abutting against the elastic pin; the guide surface is provided with a first groove and a second groove with the opening direction radially inward, wherein the groove depth of the first groove is less than the groove depth of the second groove.

[0023] In this embodiment, when the first groove abuts against the elastic pin, the lever is in the locked position, the elastic pin moves radially inward and compresses the spring. At this time, the groove wall of the first groove abuts against the outer side of the pin wall, thereby preventing the lever from accidentally sliding and thus preventing the outer decorative part from accidentally falling off the inner decorative part. When the second groove abuts against the outer side of the pin wall, the lever is in the unlocked position, and the elastic pin exits the limiting hole under the action of the spring force, so that the outer decorative part can rotate relative to the inner decorative part.

[0024] In the twelfth possible implementation in conjunction with the eleventh possible implementation of the first aspect described above, the exterior trim also has a lever guide groove for mounting the lever, and the limiting mechanism also includes a cover plate; the lever guide groove is an arc-shaped groove adapted to the lever, and the lever guide groove extends circumferentially along the center line of the arc-shaped groove; the cover plate is disposed at the opening of the lever guide groove to restrict the lever from falling out of the lever guide groove along the depth direction of the lever guide groove.

[0025] In conjunction with the first aspect and any of the possible implementations of the first aspect, the exterior trim also includes a mounting interface for connecting to a functional component.

[0026] In this embodiment of the application, an internal thread for mounting other functional components, such as a standard thread, is provided on the exterior trim to expand the functionality of the electronic device.

[0085] The following specific embodiments illustrate the implementation of this application. Those skilled in the art can easily understand other advantages and effects of this application from the content disclosed in this specification. Although the description of this application will be presented in conjunction with some embodiments, this does not mean that the features of this application are limited to this embodiment. On the contrary, the purpose of describing the application in conjunction with embodiments is to cover other options or modifications that may be derived based on the claims of this application. To provide a thorough understanding of this application, many specific details will be included in the following description. This application may also be implemented without using these details. Furthermore, to avoid confusion or obscuring the focus of this application, some specific details will be omitted in the description. It should be noted that, unless otherwise specified, the embodiments and features in the embodiments of this application can be combined with each other.

[0086] To make the objectives, technical solutions, and advantages of this application clearer, the embodiments of this application will be described in further detail below with reference to the accompanying drawings.

[0087] As mentioned earlier, to reduce the overall thickness of electronic devices, when electronic components, such as camera modules, need to protrude from the casing, decorative mounting holes can be provided on the casing. By sealing the decorative components to the casing, the casing can accommodate the protrusion of the camera module while maintaining the sealing performance of the electronic device. However, different users have different aesthetic requirements for electronic devices. Replacing decorative components requires disassembling the casing of the electronic device. This replacement process is complex, easily scratches the casing, affects the aesthetics, and repeated disassembly of the casing can affect the sealing performance of the electronic device, thus impacting its waterproof performance.

[0088] To address the aforementioned problems, this application provides a decorative component for the housing of an electronic device. This component includes an inner decorative component and an outer decorative component. The inner decorative component is sealed to the electronic device housing, while the outer decorative component is detachably connected to the inner decorative component on the outside of the electronic device housing. Thus, by replacing the outer decorative component, users can meet their needs for decorative components with different appearances and / or functions. Furthermore, because the inner decorative component and the electronic device housing are sealed, the sealing performance of the electronic device is guaranteed, preventing liquids, dust, etc., from entering the electronic device and affecting its performance. For example, different colors and patterns of outer decorative components can be used to meet users' aesthetic requirements for the electronic device. Alternatively, outer decorative components with functions such as light emission, fragrance emission, and imaging can be replaced to expand the functionality of the electronic device.

[0089] Specifically, Figure 1A An exploded view of a mobile phone 100 is shown.

[0090] In some embodiments, see Figure 1AThe mobile phone 100 includes a main body 30, a casing 20, and decorative components 10. The decorative components 10 include an inner decorative component 11 and an outer decorative component 12. The inner decorative component 11 is disposed on the inner side of the casing 20, and the outer decorative component 12 is disposed on the outer side of the casing 20. A camera module 301 is disposed on the main body 30, and the camera module 301 includes a plurality of cameras 3011. A decorative component mounting hole 201 is provided on the casing 20 for mounting the inner decorative component 11. A portion of the inner decorative component 11 passes through and protrudes from the decorative component mounting hole 201, and the inner decorative component 11 is sealed to the casing 20 on the inner side 20b of the casing 20 by a sealing portion 111. This seals the outer portion of the inner decorative component 10 with the casing, thereby ensuring the sealing performance of the mobile phone 100 after the casing 20 is installed on the main body 30, preventing liquids, dust, etc., from entering the mobile phone 100 and affecting its performance. The outer decorative component 12 and the inner decorative component 11 are detachably connected by the portion protruding from the decorative component mounting hole 201. This allows users to change decorative components with different appearances and / or functions simply by replacing the outer decorative component 12, thus improving the user experience when changing the decorative component 10. In addition, since the replacement of the decorative component does not require disassembling the outer casing 20, the sealing performance of the mobile phone 100 can be guaranteed.

[0091] In some embodiments, see Figure 1A The inner decorative part 11 is also provided with a light-transmitting part 115 adapted to the camera 3011. The camera module 301 can receive light reflected from the scene outside the mobile phone 100 through the light-transmitting part 115 to realize the photo-taking function.

[0092] further, Figure 1B An exploded view of a mobile phone 100 is shown after the inner trim 11 and outer casing 20 are sealed and assembled into the phone body 30. (Reference) Figure 1B The outer decorative part 12 can be detachably connected to the inner decorative part 11, which reduces the difficulty of disassembling the outer decorative part 12 and thus meets the user's needs for different appearances and / or functions of the decorative part 10. At the same time, since the outer shell 20 does not need to be disassembled during the replacement of the outer decorative part 12, the repeated disassembly of the outer shell 20 is avoided, which affects the sealing performance of the mobile phone 100.

[0093] In other embodiments, the inner trim 11 and the outer casing 20 can be integrally formed to further improve the sealing performance of the trim 10 and the outer casing 20.

[0094] The technical solutions of this application embodiment are described below in conjunction with the detachable connection methods applicable to the decorative part 10 in different application scenarios.

[0095] In some embodiments, the detachable connection between the outer trim 12 and the inner trim 11 is a screw connection. Figure 2AAccording to some embodiments of this application, an exploded view of a decorative element 10 and a housing 20 connected by screws is shown. (See reference...) Figure 2A The decorative component 10 includes an inner decorative component 11a and an outer decorative component 12a. The inner decorative component 11a is disposed on the inner side of the outer casing 20 and is sealed and fitted to the outer casing 20, while the outer decorative component 12a is disposed on the outer side of the outer casing 20. The inner decorative component 11a is provided with a first thread, and the outer decorative component 12a is provided with a second thread adapted to the first thread. The first thread and the second thread realize the screw connection between the outer decorative component 12a and the inner decorative component 11a.

[0096] In some implementations, a first thread is provided on the portion of the inner trim 11a that protrudes from the trim mounting hole 201. The above structure is ingenious and facilitates the removal of the outer trim 12a from the inner trim 11a.

[0097] Figure 2B It shows as Figure 2A The top view of the decorative part 10 after it is assembled with the outer casing 20. Figure 2C for Figure 2A The decorative part 10 and the outer casing 20 are along Figure 2B A cross-sectional view of the MM section line. Figure 2D for Figure 2C A magnified view of region A. In some embodiments, refer to... Figure 2D The interior trim piece 11a includes three steps—a first step 11a1, a second step 11a2, and a third step 11a3—distributed radially from the outside in, and the step surfaces of the first step 11a1, the second step 11a2, and the third step 11a3 are distributed axially upwards. Figure 2A and Figure 2D It is known that the outer diameter of the first step 11a1 is larger than the diameter of the decorative part mounting hole 201. The sealing part 111 is provided on the stepped surface of the first step 11a1 and is sealed and fitted to the inner side surface 20b of the outer shell 20. The outer diameter of the second step 11a2 is smaller than the diameter of the decorative part mounting hole 201 so that it can pass through the decorative part mounting hole 201. The stepped surface of the second step 11a2 is higher than the outer side surface 20a of the outer shell 20 so that when the outer decorative part 12a is screwed to the inner decorative part 11a, the bottom surface of the outer decorative part 12a does not contact the outer side surface 20a of the outer shell 20, thus avoiding scratching the outer shell 20. The side of the third step 11a3 is provided with an external thread 110 (first thread).

[0098] It should be noted that, in the embodiments of this application, the axial direction refers to the direction perpendicular to the decorative element mounting hole 201, for example... Figure 2A In this context, S1 is axially upward; circumferential direction refers to the circumferential direction with the axial direction as the axis of rotation, for example... Figure 2A The S2 direction in the text; radial direction refers to the direction pointing towards the center of the decorative part mounting hole 201, for example... Figure 2A The S3 direction is radially inward.

[0099] In some embodiments, reference Figures 2A to 2D The inner decorative part 11a has an external thread protruding from the decorative part mounting hole 201. The outer decorative part 12a has a ring-shaped structure, and the inner surface of the ring of the outer decorative part 12a has an internal thread 120 (second thread) that matches the external thread 110. Thus, the outer decorative part 12a can be screwed into the external thread 110 of the inner decorative part 11a through the internal thread 120. The above structure allows for the replacement of decorative parts 10 with different appearances and / or functions by replacing the outer decorative part 12a, improving the user's experience in replacing decorative parts 10.

[0100] In some embodiments, the outer decorative part 12a may have decorative parts with different colors, textures, and patterns, thereby meeting the different user requirements for the appearance of the decorative parts.

[0101] In some embodiments, the outer decorative element 12a may also be provided with other functional components to expand the functionality of the mobile phone 100. In some implementations, the functional components may be a light-emitting module, a light-diffusing plate, and a textured lens.

Figure 3B The image shows the exterior trim 12a' installed after the interior trim 11a is attached, and... Figure 2C An enlarged view of the region corresponding to area A in the middle.

[0103] refer to Figure 3A The exterior decorative component 12a′ also includes functional components such as an annular light-emitting module 1291, an annular light-diffusing plate 1292, and an annular textured lens 1293, wherein the annular light-emitting module 1291, the annular light-diffusing plate 1292, and the annular textured lens 1293 are arranged sequentially from the bottom to the opening of the annular groove 129.

[0104] refer to Figure 3A and Figure 3BIn some embodiments, the shape of the annular light-emitting module 1291 is adapted to the annular groove 129, and the annular light-emitting module 1291 is fixed to the bottom of the annular groove 129. The annular light-emitting module 1291 includes a flexible circuit 1291A with wireless charging function and a light-emitting device 1291B, wherein the flexible circuit 1291A is disposed on the bottom surface of the annular groove 129, and the light-emitting device 1291B is mounted on the flexible circuit 1291A. An annular textured lens 1293 is disposed at the opening of the annular groove 129 and seals the opening of the annular groove 129 to ensure the sealing performance of the outer decorative part 12a′ and prevent liquids, dust, etc. from entering the annular groove 129 and affecting the function of the annular light-emitting module 1291. An annular light-diffusing plate 1292 is disposed between the annular light-emitting module 1291 and the annular textured lens 1293 for uniformly distributing the light emitted by the annular light-emitting module 1291.

[0105] It is understood that the embodiments of this application do not specifically limit the shape of the light-emitting device 1291B or its assembly position in the outer decorative part 12a′. In some implementations, the light-emitting device 1291B may be a plurality of light-emitting devices uniformly distributed along a circular ring structure, such as a plurality of light-emitting diodes (LEDs) uniformly distributed along a circular ring structure. In alternative implementations, the light-emitting device 1291B may be a single ring-shaped light-emitting device, such as a ring-shaped LED.

[0106] It is understood that setting functional components such as the annular light-emitting module 1291, the annular light-diffusing plate 1292, and the annular textured lens 1293 by opening the annular groove 129 is only one example. This application can also use other forms to set functional components. For example, several grooves evenly distributed along the circumference are opened on the top surface of the outer decorative part 12a′ so that functional components such as the light-emitting module, the light-diffusing plate, and the textured lens can be set in the grooves.

[0107] In some embodiments, the functional components may be components that extend and / or enhance the functions of the mobile phone 100, including but not limited to a star filter that enables the mobile phone 100 to produce cross or other shaped starbursts when shooting starlight, an ultraviolet (UV) filter for protecting the camera module 301, other lenses that improve the shooting capabilities of the mobile phone 100, such as a panoramic lens, a compass, a fun game module (such as a component with game console functionality), etc.

[0108] In other embodiments, the functional components may also be components that enhance the portability of the mobile phone 100, such as a buckle that makes it easier for the user to hold the mobile phone 100, a stand that makes it easier to place the mobile phone 100, a tripod that makes it easier to take pictures with the mobile phone, and a gimbal that helps improve the shooting performance of the mobile phone 100.

[0109] In other embodiments, the functional component may also be other types of components, such as a light-emitting component, a mobile phone pendant, or a decorative component that can emit fragrance.

[0110] To facilitate the installation of the aforementioned functional components, in some other embodiments, the exterior trim may also be provided with an installation interface.

[0111] In some implementations, the exterior trim has internal threads for mounting functional components. Figure 4 A schematic diagram of another exterior trim piece 12a″ is shown, as follows: Figure 4 As shown, the outer trim piece 12a″ includes the aforementioned internal thread 120 for engaging with the external thread 110 of the inner trim piece 11a, and a connecting internal thread 128 for mounting other functional components. The connecting internal thread 128 can be a standard interface thread, such as a C-mount (standard lens mount, thread major diameter 25.4 mm, pitch 32 threads per inch) thread. It is understood that the connecting internal thread 128 can also be other threads designed according to the size of the outer trim piece 12a; this embodiment does not specifically limit the type of thread.

[0112] In other alternative implementations, the mounting interface on the exterior trim 12a can also be a plug-in interface or a snap-fit ​​interface, etc., which is not limited in the embodiments of this application.

[0113] To prevent the exterior trim 12 from accidentally falling off, this application also provides another trim 10. The exterior trim is detachably connected to the interior trim via a snap-fit ​​mechanism, and several pairs of protrusions restrict the circumferential rotation of the exterior trim relative to the interior trim, thereby preventing accidental detachment.

[0114] Specifically, Figure 5A An exploded view of a decorative element 10 and a housing 20 is shown. (Reference) Figure 5AThe decorative component 10 includes an inner decorative component 11b and an outer decorative component 12b. The connection method between the inner decorative component 11b and the outer shell 20 is similar to that in the previous embodiment, and will not be repeated here. Unlike the previous embodiment where the outer decorative component 12a and the inner decorative component 11a are connected by threads, in this embodiment, the inner decorative component 11b is provided with a plurality of slots 112B, and the outer decorative component 12b is provided with the same number of slots 112B and the same position as the slots 112B, so that the outer decorative component 12b can be engaged with the inner decorative component 11b through the snap fasteners 112A. In addition, the inner decorative component 11b is also provided with a first protrusion 113, and the outer decorative component 12b is also provided with a second protrusion 121 in the same number as the first protrusion 113, the same position as the first protrusion 113, and the opposite protrusion direction, so as to restrict the circumferential rotation of the outer decorative component 12b relative to the inner decorative component 11b. Furthermore, the inner circumferential surface 12b1 of the outer trim 12b cooperates with the outer circumferential surface 11b1 of the inner trim to restrict the radial movement of the outer trim 12b relative to the inner trim 11b.

[0115] Figure 5B For interior trim 11b Figure 5A A magnified view of region B in the middle. Figure 5C Bottom view of exterior trim piece 12b. (Reference) Figure 5B and Figure 5C The outer trim piece 12b has three radially inwardly oriented snap fasteners 112A evenly distributed on it. The inner trim piece 11b has a slot 112B for engaging the snap fasteners 112A. The snap fasteners 112A can engage in the slot 112B when the outer trim piece 12b is rotated, thereby restricting the axial movement of the outer trim piece 12b relative to the inner trim piece 11b.

[0116] The outer trim piece 12b has three radially inwardly oriented second protrusions 121 evenly distributed on it, and the inner trim piece 11b has a first protrusion 113 that matches the second protrusions 121. At least one of the first protrusion 113 and the second protrusion 121 is an elastic protrusion. The first protrusion 113 is used to restrict the circumferential movement of the second protrusion 121, thereby restricting the circumferential rotation of the outer trim piece 12b relative to the inner trim piece 11b.

[0117] Figure 6A According to some embodiments of this application, it is shown that Figure 5A The top view shown is of the decorative part 10 assembled with the outer casing 20. Figure 6B for Figure 6A The decorative element 10 and the outer casing 20 are shown in a cross-sectional view along the NN section line; Figure 6C for Figure 6B A magnified view of region C. (Reference) Figure 6CWhen the buckle 112A is engaged in the slot 112B, the upper surface 112A1 of the buckle 112A abuts against the lower end face 112B2 of the protrusion 112B1, and the bottom surface 12b1 of the outer decorative part 12b abuts against the outer side surface 20a of the outer shell 20, thereby restricting the axial movement of the outer decorative part 12b relative to the inner decorative part 11b.

[0118] Figure 6D This is a schematic diagram showing the adjacent sequence of the first protrusion 113 and the second protrusion 121, wherein the outer decorative part 12b is not snapped into the inner decorative part 11b. Figure 6E This is a schematic diagram showing the adjacent sequence of the first protrusion 113 and the second protrusion 121, wherein the outer decorative piece 12b is completely engaged with the inner decorative piece 11b. (Reference) Figure 6D and Figure 6E Before the buckle 112A is engaged in the slot 112B, the first protrusion 113 is to the left of the second protrusion 121, and the outer decorative piece 12b rotates clockwise (S4 direction) as shown in the figure, so that the second protrusion 121 rotates clockwise with the outer decorative piece 12b. The second protrusion 121 undergoes elastic deformation under the pressure of the right side surface 113R of the first protrusion 113 and moves radially outward. As a result, when the second protrusion 121 rotates further clockwise, the adjacency order of the first protrusion 113 and the second protrusion 121 changes. That is, after the buckle 112A is fully engaged in the slot 112B, the first protrusion 113 is exactly to the right of the second protrusion 121, and the right side surface 121R of the second protrusion 121 abuts against the left side surface 113L of the first protrusion 113, thereby achieving circumferential rotation positioning and restricting the circumferential rotation of the outer decorative piece 12b relative to the inner decorative piece 11b. The adjacency order refers to the relative positional relationship between the first protrusion 113 and the second protrusion 121, such as left and right. Thus, when the outer decorative piece 12b rotates counterclockwise, a larger torque is required to move the second protrusion 121 radially outward, thereby overcoming the resistance from the first protrusion 113 to the second protrusion 121, allowing the outer decorative piece 12b to continue rotating counterclockwise relative to the inner decorative piece 11b. This structure prevents the outer decorative piece 12b from accidentally detaching under external force when the external force is less than the force required to move the second protrusion 121 radially outward.

[0119] It should be noted that in some embodiments, the protrusion direction of the first protrusion 113 may also be other directions, such as the axial direction of the first protrusion 113. Those skilled in the art should understand that when the protrusion directions of the first protrusion 113 and the second protrusion 121 are opposite, it is possible to restrict the circumferential rotation of the outer trim piece 12b relative to the inner trim piece 11b after the adjacent sequence of the first protrusion 113 and the second protrusion 121 is misaligned. The embodiments of this application do not limit the direction of the protrusion.

[0120] It should be noted that the number of the first protrusion 113, the second protrusion 121, the buckle 112A, and the slot 112B in this application is not specifically limited. Furthermore, the positions of the first protrusion 113 and the slot 112B on the inner decorative part 11b, and the positions of the second protrusion 121 and the buckle 112A on the outer decorative part 12b, are not specifically limited in this application.

[0121] This application embodiment also provides another decorative component, wherein the method of restricting the axial movement of the outer decorative component relative to the inner decorative component is similar to the aforementioned technical solution using buckle 112A and slot 112B, and will not be described again here. The difference between this embodiment and the previous embodiment, which restricted the circumferential rotation of the outer decorative component 12b relative to the inner decorative component 12a using the first protrusion 113 and the second protrusion 121, is that this application embodiment provides a limiting hole on the inner decorative component and an elastic pin on the outer decorative component, and locks or unlocks the circumferential rotation of the outer decorative component relative to the inner decorative component when the elastic pin is inserted into or withdrawn from the limiting hole.

[0122] For example, Figure 7A According to some embodiments of this application, an exploded view of an assembly of a decorative element 10 and a housing 20 is shown. Figure 7B A view of the insertion area on the exterior trim 12c along the S5 direction is shown. (Reference) Figure 7A and Figure 7B The decorative component 10 includes an inner decorative component 11c and an outer decorative component 12c. The inner decorative component 11c has a slot 112B and a limiting hole 114. The outer decorative component 12c has a buckle 112A, a spring pin 122, and a lever 123. When the buckle 112A of the outer decorative component 12c engages with the slot 112B, the spring pin 122 can be inserted into or removed from the limiting hole 114 under the action of the lever 123, thereby locking or unlocking the outer decorative component 12c from rotating circumferentially relative to the inner decorative component 11c. Therefore, when the spring pin 122 is located in the limiting hole 114, the outer decorative component 12c cannot rotate relative to the inner decorative component 11c, thus preventing the outer decorative component 12c from falling off the inner decorative component 11c.

[0123] Figure 8A An exploded view of the exterior trim 12c is shown, as follows: Figure 8A As shown, the exterior trim 12c includes a buckle 112A, a spring pin 122, a lever 123, a cover plate 127, and screws (not shown). The exterior trim 12c also has a lever guide groove 126 with an axially upward opening and a cavity 125 with a radially outward opening, and the lever 123 is disposed in the lever guide groove 126. Figure 8B A view of cavity 125 along direction S6 is shown, as follows. Figure 8B As shown, a guide hole 124 is provided on the cavity wall 1251 of the cavity 125 in the outer decorative part 12c. Among them, the elastic pin 122 is disposed in the cavity 125 and the guide hole 124.

[0124] Figure 9A A perspective view of the resilient pin 122 is shown. Figure 9B An exploded view of the elastic pin 122 is shown.

[0125] refer to Figures 7A to 9B The resilient pin 122 includes a pin 1221, two spring mounting rods 1222, two springs 1223, and a pin wall 1224. The pin 1221 can be inserted into or withdrawn from the limiting hole 114 through the guide hole 124. The spring mounting rods 1222 extend from the inner side 1224A of the pin wall in the same direction as the pin 1221, and the end face 1222A of the spring mounting rod is lower than the end face 1221A of the pin, thereby preventing the spring mounting rods 1222 from abutting against the cavity wall 1251. The springs 1223 are sleeved on the spring mounting rods 1222, with one end of the spring 1223 abutting against the pin wall 1224 and the other end abutting against the cavity wall 1251, providing the elastic force required for the resilient pin 122 to withdraw from the limiting hole 114.

[0126] It is understood that the number of spring mounting rods 1222 and springs 1223 can also be other numbers, such as one. This application embodiment does not make a specific limitation.

[0127] Figure 10A A top view of lever 123 is shown. Figure 10B This diagram shows the second groove 1233 abutting against the elastic pin 122 when the lever 123 is in the unlocked position. Figure 10C A schematic diagram is shown showing the first groove 1232 abutting against the elastic pin 122 when the lever 123 is in the locked position. The following is in conjunction with... Figures 8A to 10C Describe in detail the structure and function of exterior trim 12c.

[0128] For reference Figure 10A The lever 123 can be an arc-shaped lever. The lever 123 includes a guide surface 1231 disposed on the concave surface of the lever 123, a first groove 1232 and a second groove 1233 formed on the guide surface 1231 with the groove opening radially inward, and a force-receiving part 1234 disposed on the convex surface of the lever 123. The depth of the first groove 1232 is less than the depth of the second groove 1233. The guide surface 1231 is used to abut against the outer side surface 1224B of the pin wall, so that when the bottom of the groove 1232 on the guide surface 1231 abuts against the outer side surface 1224B of the pin wall, the elastic pin 122 is inserted into the limiting hole 114 and the spring 1223 is compressed. And when the bottom of the groove 1233 on the guide surface 1231 of the lever 123 abuts against the outer side surface 1224B of the pin wall, the elastic pin 122 is withdrawn from the limiting hole 114 under the elastic force of the spring 1223. The force-receiving part 1234 is used to receive external loads so that the lever 123 slides along the lever guide groove 126 under the action of external loads.

[0129] refer to Figures 10A to 10C When the lever 123 is in the unlocked position, i.e., when the elastic pin 122 is located in the second groove 1233, the groove wall 1233B of the second groove 1233 abuts against the right side 1225B of the elastic pin. When the lever 123 rotates counterclockwise, the elastic pin 122 slides radially inward under the pressure of the groove wall 1233B until the elastic pin 122 is engaged in the first groove 1232, and the lever 123 is in the locked position. Figure 10C As shown. At this time, since the elastic pin 122 is located in the first groove 1232, the groove wall 1232B of the first groove 1232 abuts against the right side 1225B of the elastic pin, and the lever 123 cannot continue to rotate counterclockwise. In addition, the groove wall 1232A of the first groove 1232 abuts against the left side 1225A of the elastic pin. If the lever 123 is to be moved from the locked position to the unlocked position, the pressure of the left side 1225A of the elastic pin on the groove wall 1232A needs to be overcome, so as to avoid the lever 123 from sliding accidentally, and thus prevent the outer decorative part 12c from falling off the inner decorative part 11c.

[0130] In other embodiments, the lever 123 may also be of other shapes or may be used in other ways, such as protrusions and grooves, wedge blocks, etc., so that when different parts of the lever 123 abut against the outer side surface 1224B of the pin wall, the elastic pin 122 inserts into or exits the limiting hole 114. This application does not limit the embodiments.

[0131] refer to Figure 8B The guide hole 124 is arranged radially. When the buckle 112A is fully engaged with the slot 112B, the guide hole 124 is aligned with the limiting hole 114, and the size and shape of the guide hole 124 are adapted to the pin 1221. When the pin 1221 is inserted into the limiting hole 114 through the guide hole 124, it can restrict the circumferential rotation of the outer trim 12c relative to the inner trim 11c.

[0132] refer to Figure 8B The cavity 125 communicates with the guide hole 124 and its shape and size are adapted to the elastic pin 122. The cavity 125 includes a cavity wall 1251, which prevents the spring 1223 from moving radially when it abuts against the cavity wall 1251.

[0133] In some embodiments, the lever guide groove 126 is an arc-shaped groove adapted to the lever 123 and extends circumferentially along the centerline of the arc-shaped groove, so that the lever 123 can slide circumferentially after being installed in the lever guide groove 126, so that the first groove 1232 or the second groove 1233 abuts against the outer side surface 1224B of the pin wall. An opening 1261 is provided so that the force-receiving part 1234 of the lever 123 can extend to the outside of the outer decorative part 12c for easy operation.

[0134] It is understood that in other embodiments, the shape and extension direction of the lever guide groove 126 may also be other forms adapted to the lever 123, and the embodiments of this application are not limited thereto.

[0135] refer to Figure 8A The cover plate 127 is installed in the groove of the lever guide groove 126 by screws (not shown) to prevent the lever 123 from falling out of the lever guide groove 126 along the groove depth direction.

[0136] It is understood that in other embodiments, the limiting hole 114 may also face other directions, such as the inner side of the housing 20, and the orientation of the elastic pin 122 and the guide hole 124 may also change with the direction of the limiting hole 114. This application embodiment does not limit this.

[0137] further, Figure 11A A top view of the trim piece 10 and housing 20 after assembly is shown. Figure 11B for Figure 11A The decorative element 10 and the outer casing 20 are shown in a sectional view along the OO section line; Figure 11C for Figure 11A An enlarged view of region D, in which the elastic pin 122 is located within the first groove 1232; Figure 11D for Figure 11A An enlarged view of region D, where the elastic pin 122 is located within the second groove 1233.

[0138] refer to Figure 11C Because the first groove 1232 is shallow and the lever 123 is relatively long in the radial direction, it pushes the elastic pin 122 to move radially inward, so that the pin 1221 of the elastic pin 122 is inserted into the limiting hole 114, thereby locking the circumferential rotation of the outer decorative part 12c relative to the inner decorative part 11c. In addition, when the elastic pin 122 moves radially inward, it compresses the spring 1223, increasing the elastic deformation of the spring 1223.

[0139] refer to Figure 11D Since the second groove 1233 is deeper and the lever 123 is shorter in the radial direction, the spring 1223 releases its elastic force, and the pin 1221 exits from the limiting hole 114 under the action of the elastic force. At this time, the outer decorative part 12c can rotate circumferentially relative to the inner decorative part 11c, so that the outer decorative part 12c can be rotated to replace the decorative part.

[0140] refer to Figure 1AThis application also provides an electronic device housing, which includes any of the aforementioned decorative elements 10. This electronic device housing allows users to replace the decorative elements of the electronic device housing by removing the outer decorative elements without disassembling the housing itself. This satisfies the user's need to replace decorative elements with different appearances and / or functions while ensuring the sealing performance of the electronic device.

[0141] refer to Figure 1A This application also provides an electronic device that includes the aforementioned electronic device housing, allowing users to replace the decorative parts of the electronic device housing by removing the outer decorative parts without disassembling the electronic device. This satisfies the user's need to replace decorative parts with different appearances and / or functions while ensuring the sealing performance of the electronic device.
