Decorative components, housing components and electronic equipment

Abstract

The embodiments of the present application provide a decorative assembly, a battery cover assembly, and an electronic device. The decorative assembly is configured to be mounted on a housing and includes a decorative assembly and a decorative piece. The decorative assembly is configured to mount a component to be mounted on the housing. The decorative assembly and the decorative piece are separate components that are connected and capable of forming a concave corner on the outer side of the housing. Because the first decorative piece and the second decorative piece form a concave corner, the two surfaces forming the concave corner can be independently CNC machined, avoiding direct CNC machining of the concave corner and the appearance of CNC tool marks at the concave corner. This reduces the difficulty of CNC machining while also improving the sophistication of the decorative assembly. The first decorative piece and the second decorative piece can be independently anodized to achieve different colors for the first and second decorative pieces. This reduces the difficulty of the anodizing process while achieving a variety of colors in the appearance of the decorative assembly.

Taking a mobile phone as an example, the battery cover of the mobile phone is mounted with a camera via a decorative element, wherein the decorative element is mounted on the battery cover and the camera is mounted on the decorative element.

[0003] To enhance the decorative part's appearance, the portion protruding from the outer surface is designed with a concave corner. Decorative parts are typically one-piece structures and machined using computer numerical control (CNC) machines. However, direct CNC machining of concave corners is difficult. Furthermore, CNC machining is prone to leaving CNC tool marks on these corners, reducing the decorative part's sophistication. Avoiding CNC tool marks on these corners increases the difficulty of CNC machining.

[0004] In addition, the decorative parts are metal parts and have an integrated structure. In order to achieve the diversity of the appearance color of the decorative parts, the decorative parts need to be subjected to multiple anodizing processes, which makes the anodizing process of the decorative parts more difficult.

[0078] The technical solutions in the embodiments of the present application will be described clearly and completely below in conjunction with the drawings in the embodiments of the present application. The terms used in the following embodiments are only for the purpose of describing specific embodiments and are not intended to be limiting of the present application. As used in the specification and appended claims of the present application, the singular expressions "one", "a kind of", "said", "above", "the" and "this" are intended to also include expressions such as "one or more", unless there is a clear contrary indication in the context. It should also be understood that in the embodiments of the present application, "one or more" refers to one, two or more; "and / or" describes the association relationship of associated objects, indicating that three relationships may exist; for example, A and / or B can represent: the existence of A alone, the existence of A and B at the same time, and the existence of B alone, where A and B can be singular or plural. The character " / " generally indicates that the related objects before and after are in an "or" relationship.

[0079] References to "one embodiment" or "some embodiments" in this specification mean that a particular feature, structure, or characteristic described in conjunction with that embodiment is included in one or more embodiments of the present application. Thus, phrases such as "in one embodiment," "in some embodiments," "in other embodiments," and "in yet other embodiments" appearing in various places in this specification do not necessarily refer to the same embodiment, but rather mean "one or more but not all embodiments," unless otherwise specifically emphasized. The terms "including," "comprising," "having," and variations thereof mean "including but not limited to," unless otherwise specifically emphasized.

[0080] The "multiple" involved in the embodiments of the present application means greater than or equal to two. It should be noted that in the description of the embodiments of the present application, the words "first" and "second" are only used for the purpose of distinguishing the description and cannot be understood as indicating or implying relative importance or order.

[0081] The terms "parallel" and "perpendicular" in this application refer to "substantially parallel" and "substantially perpendicular" in actual operation. "Substantially parallel" can be understood as parallel with a certain error, and similarly, "substantially perpendicular" can be understood as perpendicular with a certain error.

[0082] The “plane” referred to in this application is a “plane substantially parallel to the horizontal plane” in actual operation.

[0083] Currently, the housings of electronic devices such as mobile phones and tablet computers are mounted with components to be mounted via decorative elements (DECO). Taking a mobile phone as an example, the battery cover of the mobile phone is mounted with a camera via a decorative element, wherein the decorative element is mounted on the battery cover and the camera is mounted on the decorative element.

[0084] Figure 1 and Figure 2 The structure of the decorative part and the battery cover is shown. Figure 1 and Figure 2 As shown, decorative piece 01 is installed in mounting hole 023 of battery cover 02. Battery cover 02 has an outer surface 021 and an inner surface 022, which are positioned opposite each other. Inner surface 022 of battery cover 02 is closer to the phone battery, while outer surface 021 of battery cover 02 is further away from the phone battery. It is understood that outer surface 021 of battery cover 02 is exposed to the outside of the phone, while inner surface 022 of battery cover 02 is hidden inside the phone. Part of decorative piece 01 protrudes from outer surface 021 of battery cover 02.

[0085] To improve the appearance of the decorative element 01, the portion of the decorative element 01 protruding from the outer surface 021 is provided with a concave corner 013. In some embodiments, the first surface 011 and the second surface 012 connected perpendicularly to the decorative element 01 form a concave corner 013, which is typically a concave right angle.

[0086] To simplify installation, decorative part 01 is typically a one-piece structure and is machined using a computer numerical control (CNC) machine. However, directly CNC-machining the concave corner 013 is difficult. Furthermore, CNC machining is prone to leaving CNC marks on the concave corner 013, reducing the finish of decorative part 01. Avoiding CNC marks on the concave corner 013 increases the difficulty of CNC machining.

[0087] Furthermore, decorative part 01 is a metal piece with an integrated structure. To achieve a variety of colors for decorative part 01, decorative part 01 needs to undergo multiple anodizing processes, which makes the anodizing process of decorative part 01 quite difficult. The entire metal decorative part 01 also increases the cost of decorative part 01.

[0088] In view of the above problems, an embodiment of the present application discloses a battery cover assembly, which can improve the sophistication of decorative parts while reducing the difficulty of CNC processing, and can achieve diversity in the appearance color of decorative parts while reducing the difficulty of anodizing process.

[0089] In some embodiments, the battery cover assembly is applied to a mobile phone.

[0090] In some embodiments, the battery cover assembly is a form of the housing assembly, and accordingly, the battery cover is a form of the housing. The housing assembly can be applied to electronic devices such as mobile phones, tablet computers, desktop computers, laptop computers, notebook computers, ultra-mobile personal computers (UMPCs), handheld computers, netbooks, personal digital assistants (PDAs), and wearable electronic devices.

[0091] Figure 3a-3c The first structure of the battery cover assembly disclosed in the embodiment of the present application is shown. Figure 3a In the figure, the left side is an isometric view of the battery cover assembly 1000, and the right side is an exploded view of the battery cover assembly 1000. In the exploded view, the decorative member 700 is not exploded. Figure 3a-3c As shown, the battery cover assembly 1000 includes a battery cover 4 and a decorative member 700 disposed on the battery cover 4. It should be noted that the decorative member 700 can be referred to as a decorative assembly.

[0092] Typically, the decorative element 700 is provided with a first mounting hole 710, which can be used to mount a camera, which may include a flash. Figure 3a-3c The camera is not displayed.

[0093] In some embodiments, the first mounting hole 710 can be used to mount other components to be mounted, such as a flash lamp. In some embodiments, the decorative member 700 can be mounted with other components to be mounted without the first mounting hole 710 .

[0094] The battery cover 4 is provided with a second mounting hole 403, which extends from the outer surface 401 of the battery cover 4 to the inner surface 402 of the battery cover 4. The decorative member 700 is mounted in the second mounting hole 403. It will be appreciated that the decorative member 700 extends through the battery cover 4. This facilitates the connection between the camera and the components inside the battery cover 4, and also facilitates the installation of the camera.

[0095] In some embodiments, the battery cover 4 may be provided with the decorative member 700 without providing the second mounting hole 403 .

[0096] In some embodiments, the decorative member 700 is a rectangular parallelepiped structure. Of course, the decorative member 700 can also be a cylindrical body with a circular or elliptical cross-section, or other shapes such as a cube or a rectangular parallelepiped, and is not limited to a rectangular parallelepiped structure.

[0097] Combined with 3a- Figure 3c As shown, the decorative element 700 includes a first decorative element 1 , a second decorative element 2 and a third decorative element 3 .

[0098] Figure 4 and Figure 5 The assembly structure of the first decorative piece 1 , the second decorative piece 2 , the third decorative piece 3 and the battery cover 4 is shown.

[0099] like Figure 4 and Figure 5 As shown, the second decorative member 2 is an annular structure. In some embodiments, the second decorative member 2 may be a circular ring structure, a quasi-circular ring structure, a rectangular ring structure, or a quasi-rectangular ring structure. The second decorative member 2 is disposed on the outer surface 401 of the battery cover 4 and is positioned around the second mounting hole 403. Alternatively, a portion of the second decorative member 2 may be disposed within the second mounting hole 403 while another portion of the second decorative member 2 is positioned around the second mounting hole 403. The entire second decorative member 2 is not limited to being positioned around the second mounting hole 403.

[0100] The third decorative piece 3 is connected to the inner surface 402 of the battery cover 4. The third decorative piece 3 passes through the second mounting hole 403 and the second decorative piece 2. The end of the third decorative piece 3 that extends beyond the second decorative piece 2 is connected to the first decorative piece 1. This facilitates camera installation. In some embodiments, the third decorative piece 3 includes a third decorative piece outer portion 301 and a third decorative piece inner portion 302, and the third decorative piece outer portion 301 and the third decorative piece inner portion 302 are integrally formed. The third decorative piece inner portion 302 is connected to the inner surface 402 of the battery cover 4; the third decorative piece outer portion 301 passes through the second mounting hole 403 and the second decorative piece 2. It is understood that the third decorative piece outer portion 301 protrudes from the outer surface 401 of the battery cover 4; the third decorative piece outer portion 301 is connected to the first decorative piece 1; and the second decorative piece 2 surrounds the third decorative piece outer portion 301 circumferentially around the third decorative piece 3, i.e., around the second mounting hole 403.

[0101] The first decorative member 1 is disposed on the second decorative member 2 and is connected to the outer surface 401 of the battery cover 4 via the second decorative member 2. It is understood that the first decorative member 1 is located at the end of the second decorative member 2 away from the battery cover 4. The first decorative member 1 covers the third decorative member 3 and a portion of the second decorative member 2. Thus, on the outside of the battery cover 4, the first and second decorative members 1 and 2 cover the portion of the third decorative member 3 that protrudes from the outer surface 401 of the battery cover 4. That is, on the outside of the battery cover 4, the first and second decorative members 1 and 2 cover the periphery of the third decorative member 3, preventing the third decorative member 3 from being exposed on the outer surface 401 of the battery cover 4. Therefore, the third decorative member 3 does not affect the appearance of the decorative member 700. In some embodiments, the third decorative member 3 is non-metallic, for example, plastic or other low-cost non-metallic member. Compared to existing decorative members made entirely of metal, the decorative member 700 is less expensive.

[0102] In some embodiments, the first decorative piece 1 can be passed through the second decorative piece 2 and the second mounting hole 403 and connected to the third decorative piece 3. In this case, the end of the first decorative piece 1 that passes through the second mounting hole 403 protrudes from the inner surface 402 of the battery cover 4, and the third decorative piece 3 does not extend into the second mounting hole 403; the first decorative piece 1 and the second decorative piece 2 also cooperate to cover the portion of the third decorative piece 3 that protrudes from the outer surface 401 of the battery cover 4.

[0103] It should be noted that, without considering cost, the first decorative piece 1 and the third decorative piece 3 are an integrated structure, that is, the first decorative piece 1 and the third decorative piece 3 are the same component. In some embodiments, the first decorative piece 1 and the third decorative piece 3 are both part of a decorative assembly, that is, the decorative assembly includes the first decorative piece 1 and the third decorative piece 3.

[0104] The first decorative element 1 and the second decorative element 2 form a first concave corner 720. The first concave corner 720 can be distributed only on one side of the decorative element 700, or can be distributed on at least two sides of the decorative element 700, depending on the actual situation.

[0105] In some embodiments, the first surface 101 of the first decorative element 1 and the second surface 201 of the second decorative element 2 form a first concave corner 720. The first surface 101 is a portion of the first peripheral sidewall 102 of the first decorative element 1, and the second surface 201 is a portion of the top surface 207 of the second decorative element 2. The top surface 207 is the end surface of the second decorative element 2 away from the battery cover 4.

[0106] In some embodiments, the first surface 101 and the second surface 201 are both planes, and the first surface 101 is perpendicular to the second surface 201. In this case, the first concave corner 720 is a concave right angle. Of course, the first surface 101 can also be inclined relative to the second surface 201, and is not limited to being perpendicular.

[0107] In the decorative part 700, the first decorative part 1 and the second decorative part 2 are two separate components. The first surface 101 of the first decorative part 1 and the second surface 201 of the second decorative part 2 form a first concave corner 720. The CNC can process the first surface 101 and the second surface 201 separately, avoiding direct CNC processing of the first concave corner 720 and avoiding the appearance of CNC knife marks at the first concave corner 720, thereby reducing the difficulty of CNC processing while improving the sophistication of the decorative part 700.

[0108] Since the second decorative piece 2 is arranged on the outer surface 401 of the battery cover 4, and the first decorative piece 1 is used to be arranged at the end of the second decorative piece 2 away from the battery cover 4, the first decorative piece 1 and the second decorative piece 2 are both located on the outside of the battery cover 4. Since the first decorative piece 1 and the second decorative piece 2 are two separate components, the first decorative piece 1 and the second decorative piece 2 can be separately treated by an anodizing process to achieve different colors of the first decorative piece 1 and the second decorative piece 2, especially different colors of the first surface 101 of the first decorative piece 1 and the second surface 201 of the second decorative piece 2. Compared with achieving different colors of two surfaces of a component, the diversity of the appearance color of the decorative piece 700 is achieved while reducing the difficulty of the anodizing process.

[0109] In the battery cover assembly 1000, the decorative member 700 is fixedly and hermetically connected to the battery cover 4. Both components of the decorative member 700 that are connected are fixedly and hermetically connected to ensure the stability and sealing performance of the battery cover assembly 1000. In some embodiments, the third decorative member 3 is fixedly and hermetically connected to the inner surface 402 of the battery cover 4, the second decorative member 2 is fixedly connected to the outer surface 401 of the battery cover 4, and both the second decorative member 2 and the third decorative member 3 are fixedly and hermetically connected to the first decorative member 1.

[0110] Figure 5 An implementation structure of the sealing connection and fixed connection mentioned above is shown.

[0111] like Figure 5 As shown, the first decorative piece 1 and the second decorative piece 2 are fixedly connected and sealed by a first adhesive layer 5. It is understood that the first adhesive layer 5 has a waterproof effect. To facilitate installation, the second decorative piece 2 is provided with a positioning groove 202, and the first adhesive layer 5 is positioned within the positioning groove 202.

[0112] Without interfering with other structures and components, the first adhesive layer 5 should cover the surface of the first decorative piece 1 close to the second decorative piece 2 as much as possible to improve the connection strength and sealing effect between the first decorative piece 1 and the second decorative piece 2.

[0113] The second decorative member 2 and the outer surface 401 of the battery cover 4 are fixedly connected via a second adhesive layer 6. It will be appreciated that the second adhesive layer 6 provides a cushioning effect to prevent damage to the battery cover 4. In some embodiments, the second decorative member 2 and the outer surface 401 of the battery cover 4 are fixedly connected and sealed. In this case, the second adhesive layer 6 provides a waterproof effect.

[0114] Without interfering with other structures and components, the second adhesive layer 6 should cover the surface of the second decorative component 2 close to the battery cover 4 as much as possible to improve the connection strength and buffering effect between the second decorative component 2 and the battery cover 4.

[0115] The third decorative part 3 and the first decorative part 1 are fixedly connected by screws 8 and fixedly connected and sealed by the first glue layer 9. Among them, the third decorative part outer part 301 of the third decorative part 3 and the first decorative part 1 are fixedly connected by screws 8 and fixedly connected and sealed by the first glue layer 9. In some embodiments, the screws 8 can be replaced by other fasteners, such as bolts, pins, etc. It can be understood that the first glue layer 9 has a waterproof effect. The specific distribution of the first glue layer 9 is selected according to actual conditions. For example, the first glue layer 9 can be distributed on the periphery of the second through hole 303. Without interfering with other structures and components, the first glue layer 9 should cover the surface of the third decorative part 3 close to the first decorative part 1 as much as possible to improve the connection strength and sealing effect of the third decorative part 3 and the first decorative part 1.

[0116] The third decorative member 3 and the inner surface 402 of the battery cover 4 are fixedly connected and sealed by the third adhesive layer 7. The third decorative member inner portion 302 of the third decorative member 3 and the inner surface 402 of the battery cover 4 are fixedly connected and sealed by the third adhesive layer 7. It is understood that the third adhesive layer 7 has a waterproof effect.

[0117] Without interfering with other structures and components, the third adhesive layer 7 should cover the surface of the inner portion 302 of the third decorative piece close to the battery cover 4 as much as possible to improve the connection strength and sealing effect between the third decorative piece 3 and the battery cover 4.

[0118] In the above-mentioned implementation structure, fixed connection and sealed connection are achieved by dispensing glue and back glue, which simplifies the installation structure of the entire decorative part 700 and reduces the installation space and operation space reserved for sealing, thereby reducing the volume of the entire decorative part 700 and the volume of the entire battery cover assembly 1000.

[0119] In some embodiments, the back glue layer can be replaced by a dispensing glue layer, and the dispensing glue layer can be replaced by a back glue layer; or, the two components in the battery cover assembly 1000 that need to be sealed and connected are sealed and connected by a sealing ring or other sealing members, and the two components in the battery cover assembly 1000 that need to be fixedly connected are fixedly connected by a snap-fit ​​structure or other fixing structure.

[0120] In the battery cover assembly 1000 , the first decorative piece 1 and the second decorative piece 2 are positioned and matched, which simplifies the installation of the first decorative piece 1 and improves the installation accuracy of the first decorative piece 1 . Figure 5 The positioning and matching structure of the first decorative piece 1 and the second decorative piece 2 is also shown.

[0121] like Figure 5As shown, the second decorative member 2 is provided with a positioning groove 202, and the first decorative member 1 is positioned within the positioning groove 202, with the first decorative member 1 and the positioning groove 202 being positioned and matched. In some embodiments, the second decorative member 2 is annular, that is, the positioning groove 202 is annular, and the groove sidewalls of the positioning groove 202 surround the first peripheral sidewall 102 of the first decorative member 1. The groove sidewalls of the positioning groove 202 and the first peripheral sidewall 102 of the first decorative member 1 are positioned and matched, that is, the first decorative member 1 and the second decorative member 2 are positioned circumferentially. In this case, the portion of the first decorative member 1 located outside the positioning groove 202 and the second decorative member 2 form a first concave corner 720, that is, the first surface 101 of the first decorative member 1 is located outside the positioning groove 202.

[0122] The positioning accuracy of the first decorative element 1 and the second decorative element 2 is selected according to actual conditions. For example, the first decorative element 1 and the second decorative element 2 can be precisely positioned or roughly positioned.

[0123] In some embodiments, the first decorative piece 1 and the second decorative piece 2 can be positioned by other positioning structures, such as a positioning structure in which a positioning column cooperates with a positioning hole, but is not limited to the above-mentioned implementation structure.

[0124] The following combination Figures 6a-6c , the structures of the first decorative part 1 and the third decorative part 3 in the decorative part 700 are introduced.

[0125] like Figures 6a-6c As shown, the first decorative member 1 is provided with a first through hole 103, and the third decorative member 3 is provided with a second through hole 303. The coaxiality of the first through hole 103 and the second through hole 303 is within a set range. For example, the first through hole 103 and the second through hole 303 are arranged coaxially. The first through hole 103 and the second through hole 303 form a first mounting hole 710 for mounting a camera. Figures 6a-6c No camera is shown.

[0126] To ensure the installation effect of the camera, the first decorative piece 1 and the third decorative piece 3 are positioned and matched. In some embodiments, the first decorative piece 1 is provided with a first positioning column 10, and the third decorative piece 3 is provided with a first positioning hole 11, wherein the first positioning hole 11 and the first positioning column 10 are positioned and matched.

[0127] The first positioning column 10 can be one or more than two. In order to improve the positioning effect, the first positioning column 10 can be two or more, for example, Figure 6a Four first positioning posts 10 are shown. As for the specific positions of the first positioning posts 10, without interfering with other components and structures, the first positioning posts 10 should be distributed in as many positions as possible, as close as possible to the corners of the first decorative element 1, and as evenly distributed as possible to improve the positioning effect of the first decorative element 1 and the third decorative element 3.

[0128] The number and distribution of the first positioning holes 11 refer to the first positioning posts 10 and are not described again here.

[0129] The cross-section of the first positioning post 10 can be circular, elliptical, square, rectangular, or arcuate, etc. It is understood that the cross-section of the first positioning post 10 is perpendicular to the height direction of the first positioning post 10, that is, the cross-section of the first positioning post 10 is perpendicular to the axial direction of the first positioning post 10.

[0130] The positions of the first positioning hole 11 and the first positioning post 10 can be interchanged, that is, the first positioning post 10 is set on the third decorative piece 3, and the first positioning hole 11 is set on the first decorative piece 1. In addition, the first decorative piece 1 and the third decorative piece 3 can be positioned by other positioning structures, not limited to the form of positioning posts and positioning holes.

[0131] In some embodiments, the third mounting member 3 and the battery cover 4 are positioned and matched, which simplifies the installation of the third mounting member 3 and improves the installation accuracy of the third mounting member 3. Figure 7 and Figure 8 The structure of the third mounting member 3 and the battery cover 4 being positioned and matched is shown.

[0132] like Figure 7 and Figure 8 As shown, the third decorative member outer portion 301 of the third decorative member 3 passes through the second mounting hole 403 and protrudes from the outer surface 401 of the battery cover 4. The third decorative member outer portion 301 is positioned and matched with the second mounting hole 403. It can be understood that the outer peripheral side wall of the third decorative member outer portion 301 and the hole wall of the second mounting hole 403 are positioned and matched, and the third mounting member 3 and the battery cover 4 are circumferentially positioned.

[0133] The positioning accuracy of the third decorative element outer portion 301 and the second mounting hole 403 is selected according to actual conditions, and the third decorative element outer portion 301 and the second mounting hole 403 are precisely positioned or roughly positioned.

[0134] In some embodiments, the third decorative member 3 and the second mounting hole 403 may be positioned by other positioning structures, such as a positioning structure in which a positioning column cooperates with a positioning hole, and is not limited to the above-mentioned implementation structure.

[0135] Figures 9-12 Shown Figure 3a The assembly process of the battery cover assembly 1000 is shown.

[0136] like Figure 9As shown, the first adhesive layer 5 is disposed on the first decorative member 1, and the first decorative member 1 is fixed to the positioning groove 202 of the second decorative member 2 via the first adhesive layer 5. The first decorative member 1, the first adhesive layer 5, and the second decorative member 2 are assembled into a first assembly 100, wherein the groove sidewall 203 of the positioning groove 202 in the first assembly 100 is positioned and matched with the first peripheral sidewall 102 of the first decorative member 1.

[0137] Flip Figure 9 The first assembly 100 is shown so that the first assembly 100 is in Figure 10 The status shown. Figure 10 As shown, the second adhesive layer 6 is disposed on the second decorative component 2 in the first assembly 100 . The second adhesive layer 6 and the first assembly 100 are assembled to form a second assembly 200 .

[0138] like Figure 11 As shown, the third adhesive layer 7 is disposed on the inner surface 402 of the battery cover 4 and is located outside the second mounting hole 403. The third decorative member 3 passes through the second mounting hole 403 of the battery cover 4. The third decorative member 3 and the second mounting hole 403 are positioned and matched, and the third decorative member 3 is fixedly connected to the battery cover 4 via the third adhesive layer 7. The third decorative member 3, the third adhesive layer 7, and the battery cover 4 are assembled into a third assembly 300.

[0139] Flip Figure 11 The third component 300 is shown so that the third component 300 is in Figure 12 The status shown. Figure 12 As shown, the first adhesive layer 9 is set on the third decorative piece 3 of the third component 300; Figure 10 The second assembly 200 is shown so that the second assembly 200 is in Figure 12 In the state shown, the second component 200 is Figure 10 The second adhesive layer 6 shown, Figure 12 The first dispensing layer 9 and the screw 8 are fixed to the third component 300. The second component 200 and the third component 300 are assembled to form the battery cover assembly 1000.

[0140] The positioning and sealing involved in the above installation process can be referred to the previous description and will not be repeated here.

[0141] In some embodiments, the Figure 11 The third decorative piece 3 and the battery cover 4 are assembled, and then Figure 9 The assembly of the first decorative element 1 and the second decorative element 2 is shown.

[0142] It should be noted that after the structure of the decorative member 700 is changed, the assembly process of the battery cover assembly 1000 can be appropriately changed and is not limited to Figures 9-12 The assembly process is shown.

[0143] Figure 13a-Figure 13c The second structure of the battery cover assembly disclosed in the embodiment of the present application is shown. Figure 13a-Figure 13c As shown, the battery cover assembly 1000 includes a battery cover 4 and a decorative member 700 disposed on the battery cover 4. The decorative member 700 includes a first decorative member 1, a second decorative member 2 and a third decorative member 3.

[0144] Figure 13a-Figure 13c The battery cover 4 shown here can refer to the above description of the first structure of the battery cover assembly 1000, which will not be repeated here.

[0145] Figure 13a-Figure 13c The decorative element 700 shown is different from the decorative element 700 in the first structure. Figure 13a-Figure 13c The decorative part 700 shown differs from the decorative part 700 in the first structure mainly in that the structure of the second decorative part 2 is different, the structure of the first decorative part 1 is different, the connection related to the second decorative part 2 is different, and the connection related to the first decorative part 1 is different.

[0146] like Figure 13a-Figure 13c As shown, the second decorative member 2 is disposed on the outer surface 401 of the battery cover 4, the third decorative member 3 is connected to the inner surface 402 of the battery cover 4, a portion of the first decorative member 1 is disposed on the second decorative member 2, a portion of the first decorative member 1 is disposed on the outer surface 401 of the battery cover 4, and the first decorative member 1 is connected to the third decorative member 3. It is understood that a portion of the first decorative member 1 is disposed on the end of the second decorative member 2 away from the battery cover 4.

[0147] like Figure 14 As shown, the first decorative piece 1 and the second decorative piece 2 form a first concave corner 720 and a second concave corner 730. In some embodiments, the first decorative piece 1 and the second decorative piece 2 only form the second concave corner 730. It can be understood that the first concave corner 720 and the second concave corner 730 are two different structures of concave corners.

[0148] For the structure of the first concave corner 720 and the technical effects produced therefrom, please refer to the above description of the first structure of the battery cover assembly 1000, which will not be repeated here.

[0149] In some embodiments, the first decorative member 1 and the second decorative member 2 are joined circumferentially around the decorative member 700, and the first peripheral sidewall 102 of the first decorative member 1 and the second peripheral sidewall 206 of the second decorative member 2 form a second concave corner 730 at the joint. This allows CNC machining of the first peripheral sidewall 102 and the second peripheral sidewall 206 to form the second concave corner 730 independently, avoiding CNC machining of the second concave corner 730 and the appearance of CNC tool marks at the second concave corner 730. This reduces the difficulty of CNC machining while improving the sophistication of the decorative member 700. It also avoids the appearance of rounded corners at the second concave corner 730, improving the appearance of the decorative member 700.

[0150] The specific position of the second concave corner 730 on the periphery of the decorative member 700 is selected according to actual conditions. For example, the second concave corner 730 is close to the rounded corner of the decorative member 700, which is not limited herein.

[0151] The number of second concave corners 730 can be one or more, depending on actual needs. In some embodiments, there are two second concave corners 730 and one second decorative member 2, with one second concave corner 730 located at a first end of the circumference of the second decorative member 2 and the other second concave corner 730 located at a second end of the circumference of the second decorative member 2.

[0152] In some embodiments, there are three or more second concave corners 730 and two or more second decorative members 2. For example, there are three second concave corners 730 and two second decorative members 2, with one second concave corner 730 located at the first circumferential end of one second decorative member 2, another second concave corner 730 located at the second circumferential end of one second decorative member 2, and another second concave corner 730 located at the first circumferential end of another second decorative member 2. It should be noted that when there are two or more second decorative members 2, any two second decorative members 2 are sequentially distributed along the circumference of the second mounting hole 403.

[0153] In actual operation, the specific shape of the second decorative member 2 may be selected according to the position of the second concave corner 730 .

[0154] In the battery cover assembly 1000, since the second decorative piece 2 is arranged on the outer surface 401 of the battery cover 4, the first decorative piece 1 is arranged on the outer surface 401 of the battery cover 4 and the second decorative piece 2 is at one end away from the battery cover 4, the first decorative piece 1 and the second decorative piece 2 are both located on the outside of the battery cover 4. Since the first decorative piece 1 and the second decorative piece 2 are two separate components, the first decorative piece 1 and the second decorative piece 2 can be separately treated by an anodizing process to achieve different colors of the first decorative piece 1 and the second decorative piece 2, especially the first surface 101 of the first decorative piece 1 and the second surface 201 of the second decorative piece 2 are different in color, and the first peripheral side wall 102 of the first decorative piece 1 and the second peripheral side wall 206 of the second decorative piece 2 are different in color. Compared with achieving different colors of two surfaces of a component, the difficulty of the anodizing process is reduced while achieving the diversity of the appearance color of the decorative piece 700.

[0155] like Figure 15 As shown, the third decorative member 3 passes through the second mounting hole 403. Around the circumference of the third decorative member 3, the second decorative member 2 surrounds a portion of the third decorative member 3, while the first decorative member 1 surrounds another portion. It is understood that around the circumference of the second mounting hole 403, the second decorative member 2 surrounds a portion of the second mounting hole 403, while the first decorative member 1 surrounds another portion of the second mounting hole 403. This facilitates the formation of a second concave corner 730 between the second decorative member 2 and the first decorative member 1. In this case, the first decorative member 1 covers the third decorative member 3 and a portion of the second decorative member 2. Thus, on the outside of the battery cover 4, the first and second decorative members 1 and 2 cover the periphery of the third decorative member 3, preventing the third decorative member 3 from being exposed on the outer surface 401 of the battery cover 4. Therefore, the third decorative member 3 does not affect the appearance of the decorative member 700. In some embodiments, the third decorative member 3 is non-metallic, for example, plastic or other low-cost non-metallic components. Compared to existing decorative members constructed entirely of metal, the decorative member 700 is less expensive.

[0156] In some embodiments, the second decorative element 2 may be an annular structure, the third decorative element 3 passes through the second mounting hole 402 and the second decorative element 2 , and the first decorative element 1 surrounds a portion of the third decorative element 3 in the circumferential direction of the third decorative element 3 .

[0157] In some embodiments, the first decorative member 1 passes through the second mounting hole 403, the third decorative member 3 does not pass through the second mounting hole 403, and the second decorative member 2 is disposed around the periphery of the second mounting hole 403 of the battery cover 4. Around the circumference of the second mounting hole 403, the second decorative member 2 surrounds a portion of the second mounting hole 403, while the first decorative member 1 surrounds another portion of the second mounting hole 403. Alternatively, a portion of the second decorative member 2 may be disposed within the second mounting hole 403, while another portion of the second decorative member 2 is disposed around the periphery of the second mounting hole 403, and the embodiment is not limited to the above.

[0158] For the structure of the third decorative member 3 and the assembly relationship between the third decorative member 3 and the battery cover 4 , reference may be made to the above description of the first structure of the battery cover assembly 1000 , which will not be repeated here.

[0159] In the battery cover assembly 1000, to ensure stability and sealing, the decorative member 700 is fixedly and hermetically connected to the battery cover 4, and the two connected components of the decorative member 700 are fixedly and hermetically connected. In some embodiments, the third decorative member 3 is fixedly and hermetically connected to the inner surface 402 of the battery cover 4, the second decorative member 2 is fixedly connected to the outer surface 401 of the battery cover 4, and both the second decorative member 2 and the third decorative member 3 are fixedly and hermetically connected to the first decorative member 1, which is used to be fixedly connected to the outer surface 401 of the battery cover 4.

[0160] Figure 15 The embodiment of the sealing connection and fixed connection mentioned above is shown. Figure 15 As shown, the first decorative piece 1 and the second decorative piece 2 are fixedly connected and sealed by a second adhesive layer 12. It is understood that the second adhesive layer 12 has a waterproof effect. To facilitate adhesive dispensing, the second decorative piece 2 is provided with a first adhesive dispensing groove 205, and the second adhesive layer 12 is located in the first adhesive dispensing groove 205.

[0161] The specific positions of the second glue dispensing layer 12 and the first glue dispensing groove 205 can be selected according to actual needs, as long as the connection requirements are met and interference with other components and structures is avoided.

[0162] The outer surface 401 of the second decorative member 2 and the battery cover 4 is formed by the second adhesive layer 6 and Figure 19 The third adhesive layer 17 is shown as being fixedly connected. It will be appreciated that the second adhesive layer 6 and the third adhesive layer 17 provide a cushioning effect to prevent damage to the battery cover 4. In some embodiments, the second decorative element 2 and the outer surface 401 of the battery cover 4 are fixedly connected and sealed. In this case, both the second adhesive layer 6 and the third adhesive layer 17 provide a waterproofing effect.

[0163] Without interfering with other structures and components, the second adhesive layer 6 should cover the surface of the second decorative element 2 close to the battery cover 4 as much as possible to improve the connection strength between the second decorative element 2 and the battery cover 4.

[0164] In order to facilitate the arrangement of the third adhesive layer 17, the second decorative element 2 is provided with Figure 16a As shown in the second glue dispensing groove 204 , the third glue dispensing layer 17 is located in the second glue dispensing groove 204 .

[0165] The specific positions of the third glue dispensing layer 17 and the second glue dispensing groove 204 are selected according to actual conditions, as long as the connection requirements are met and interference with other components and structures is avoided.

[0166] The specific structure of the fixed connection and the sealed connection between the first decorative member 1 and the third decorative member 3 can be referred to the above description of the first structure of the battery cover assembly 1000, which will not be repeated here.

[0167] like Figure 15 As shown, the first decorative member 1 and the outer surface 401 of the battery cover 4 are fixedly connected via the fourth adhesive layer 13. It will be appreciated that the fourth adhesive layer 13 provides a cushioning effect to prevent damage to the battery cover 4. In some embodiments, the first decorative member 1 and the outer surface 401 of the battery cover 4 are fixedly connected and sealed. In this case, the fourth adhesive layer 13 provides a waterproof effect.

[0168] Without interfering with other structures and components, the fourth adhesive layer 13 should cover the surface of the first decorative component 1 close to the outer surface 401 as much as possible to improve the connection strength between the first decorative component 1 and the battery cover 4.

[0169] The specific structure of the fixed and sealed connection between the third decorative member 3 and the inner surface 402 of the battery cover 4 can be referred to the above description of the first structure of the battery cover assembly 1000 and will not be repeated here.

[0170] In the above-mentioned implementation structure, fixed connection and sealed connection are achieved by dispensing glue and back glue, which simplifies the installation structure, reduces the installation space and operation space required for sealing, and reduces the volume.

[0171] In some embodiments, the back glue layer can be replaced by a dispensing glue layer, or the dispensing glue layer can be replaced by a back glue layer; or, the two components in the battery cover assembly 1000 that need to be sealed and connected are sealed and connected by a sealing ring or other sealing members, or the two components in the battery cover assembly 1000 that need to be fixedly connected are fixedly connected by a snap-fit ​​structure or other fixing structure.

[0172] In the battery cover assembly 1000 , the third mounting member 3 and the battery cover 4 are positioned and matched.
