[0002] The embodiments of the present application relate to the field of electronic devices, and in particular to a housing assembly and an electronic device. Background Art

[0003] In recent years, near field communication (NFC) technology has been widely used, and more and more users use NFC technology to realize mobile payment and other functions. At the same time, with the continuous development of electronic product forms, there is a trend that the size of electronic device camera decoration parts continues to increase, and the number of cameras continues to increase. NFC antennas are generally designed near camera decoration parts. This development trend of electronic devices compresses the design space of NFC antennas, thereby affecting the performance of NFC antennas.

[0004] Therefore, how to design an NFC antenna solution that is compatible with large-sized camera decorations while ensuring the performance of the NFC antenna has become a bottleneck in the architecture stacking. Summary of the invention

[0005] The embodiments of the present application provide a housing assembly and an electronic device that can be suitable for large-sized camera decorations while ensuring the performance of an NFC antenna.

[0006] In a first aspect, a shell assembly is provided, which is applied to an electronic device, and the shell assembly includes: a back cover; a camera decoration, which is installed on the back cover; a near-field communication NFC antenna, which is attached to the camera decoration; wherein the projection of the NFC antenna along a first direction is within the range of the projection of the camera decoration along the first direction, and the first direction is the thickness direction of the electronic device.

[0007] In the shell assembly provided in the embodiment of the present application, the NFC sticker is applied on the camera decoration, and along the thickness direction of the electronic device, the projection of the NFC antenna is located within the projection range of the camera decoration. In other words, the NFC antenna will not occupy the space outside the camera decoration, and will not be affected by the size of the camera decoration. At the same time, since the NFC antenna is located on the inside of the camera decoration, the antenna clearance environment is good, so it will not affect the performance of the NFC antenna and the performance of other surrounding antennas. In addition, the problem of blind spots for reading small cards under large-size camera decorations can also be solved, thereby increasing the user experience.

[0008] In combination with the first aspect, in certain implementations of the first aspect, the camera decoration includes a first decoration and a second decoration, the first decoration is arranged on a side of the second decoration away from the back cover, the projection of the first decoration along the first direction is within the range of the projection of the second decoration along the first direction, and the projection of the NFC antenna along the first direction is within the range of the projection of the first decoration along the first direction.

[0009] In combination with the first aspect, in certain implementations of the first aspect, the first decorative piece, the NFC antenna, and the second decorative piece are stacked along a first direction, and the NFC antenna is located between the first decorative piece and the second decorative piece.

[0010] In combination with the first aspect, in some implementations of the first aspect, the NFC antenna is attached to a side of the first decorative member close to the back cover, or the NFC antenna is attached to a side of the second decorative member away from the back cover.

[0011] In the housing assembly provided in the embodiment of the present application, the camera decoration includes a first decoration and a second decoration, and the NFC antenna can be arranged between the first decoration and the second decoration, and along the thickness direction of the electronic device, the projection of the first decoration is located within the range of the projection of the second decoration, and the projection of the NFC antenna is located within the range of the projection of the first decoration. In other words, the NFC antenna will not occupy the space outside the first decoration, and will not be affected by the size of the camera decoration. At the same time, since the NFC antenna is located on the inner side of the first decoration, the antenna clearance environment is good, so it will not affect the performance of the NFC antenna and the performance of other surrounding antennas. In addition, the problem of blind spots for reading small cards under large-size camera decorations can also be solved, thereby increasing the user experience.

[0012] In combination with the first aspect, in certain implementations of the first aspect, the second decorative piece includes a metal part and a non-metal part, the first decorative piece, the second decorative piece, and the NFC antenna are stacked along a first direction, the second decorative piece is located between the first decorative piece and the NFC antenna, and the NFC antenna is attached to a side of the non-metal part close to the back cover.

[0014] In combination with the first aspect, in some implementations of the first aspect, the first decorative piece is made of a non-metallic material, and the second decorative piece is made of a metallic material.

[0015] The first decorative piece may be made of non-metallic materials such as glass and ceramics, which is not limited in the present application.

[0016] In the shell assembly provided in the embodiment of the present application, the second decorative piece can obtain a non-metallic part through an injection molding process, and the NFC antenna can be attached to the side of the non-metallic part close to the back cover. In other words, the NFC antenna can be arranged between the first decorative piece and the second decorative piece, or between the second decorative piece and the back cover. The various settings of the NFC antenna will not occupy the space outside the first decorative piece, so it will not be affected by the size of the camera decorative piece. At the same time, since the NFC antenna is located on the inner side of the first decorative piece, the antenna clearance environment is good, so it will not affect the performance of the NFC antenna and the performance of other surrounding antennas. In addition, the problem of blind spots for reading small cards under large-size camera decorative pieces can also be solved, thereby increasing the user experience.

[0017] In combination with the first aspect, in certain implementations of the first aspect, the NFC antenna includes at least one feeding point, and a projection of the at least one feeding point along the first direction is located inside a projection area of ​​the camera decoration along the first direction.

[0018] Further, a projection of the at least one feeding point along the first direction is located inside a projection area of ​​the first decorative element along the first direction.

[0019] In combination with the first aspect, in some implementations of the first aspect, at least one feeding point is electrically connected to a mainboard of the electronic device.

[0020] It is understandable that the NFC antenna can be directly fed to the mainboard, that is, there is no need to set a mainboard bracket on the mainboard of the electronic device, which can reduce the overall thickness and weight of the electronic device and effectively utilize the thinning of the electronic device.

[0021] In combination with the first aspect, in some implementations of the first aspect, the electronic device includes a camera, and when the shell assembly is installed on the electronic device, a projection of the NFC antenna along the first direction does not overlap with a projection of the camera along the first direction.

[0022] It should be understood that the camera can be arranged within the coverage of the camera decoration, and further, the camera can also be arranged within the coverage of the first decoration. In other words, the camera decoration or the first decoration can protect the camera and prevent the camera from being contaminated.

[0023] When the shell assembly provided by the embodiment of the present application is installed on an electronic device, the projection of the NFC antenna along the thickness direction of the electronic device does not overlap with the projection of the camera along the thickness direction of the electronic device, that is, the NFC antenna can surround the camera but will not block the camera, thereby ensuring that the camera can work normally.

[0024] In combination with the first aspect, in certain implementations of the first aspect, the camera decoration is a non-planar structure, and the NFC antenna is a non-planar structure obtained by a bending process and / or a welding process to adapt to the camera decoration.

[0028] It should be understood that by providing the ferrite, the FPC antenna and the metal decorative part can be isolated, thereby avoiding the influence of the metal decorative part on the FPC antenna.

[0029] In combination with the first aspect, in some implementations of the first aspect, the housing assembly further includes a magnetic isolation sheet, and the magnetic isolation sheet is used to isolate the magnetism of the ferrite.

[0030] It should be understood that laying a magnetic isolation sheet in the interference area of ​​the camera can reduce the impact of ferrite magnetism on the camera.

[0031] In combination with the first aspect, in certain implementations of the first aspect, the FPC antenna and the ferrite are respectively obtained through waterproof and dustproof processes, wherein the FPC antenna is obtained through a separate waterproof process, and the ferrite is obtained through a polyethylene terephthalate plastic PET film waterproof edging process.

[0032] The shell assembly provided in the present application can perform separate waterproof and dustproof process treatments on the FPC antenna and the ferrite, thereby ensuring the waterproof and dustproof effects of the FPC antenna and the ferrite.

[0033] In a second aspect, an electronic device is provided, comprising: a camera; a housing assembly according to the first aspect and any one of its implementations; and a camera decoration of the housing assembly for decorating the camera.

[0034] It should be understood that the camera decoration can protect the camera and the NFC antenna and can prevent the camera and the NFC antenna from being exposed, that is, the camera decoration can make the camera waterproof and dustproof, and play a protective and decorative role.

[0035] In combination with the second aspect, in some implementations of the second aspect, the electronic device further includes a mainboard, and the mainboard is electrically connected to the NFC antenna of the housing assembly.

[0036] In the electronic device provided in the embodiment of the present application, the NFC antenna does not need to bypass the camera decoration, that is, the NFC antenna will not occupy the space outside the camera decoration, and will not be affected by the size of the camera decoration. And because the NFC antenna is located on the inner side of the camera decoration, the antenna clearance environment is good, so it will not affect the performance of the NFC antenna and the performance of other surrounding antennas. In addition, the electronic device provided in the embodiment of the present application can also solve the problem of blind spots for reading small cards under large-sized camera decorations, and increase the user experience. In addition, the NFC antenna can be directly fed to the motherboard of the electronic device, so there is no need to set a motherboard bracket on the main board of the electronic device, which can reduce the overall thickness and weight of the electronic device, and utilize the thinning of the electronic device. At the same time, when the camera decoration is designed as a non-planar structure, the NFC antenna can be made to fit camera decorations of various structures through a bending process and / or a welding process.

[0052] The electronic device described in the embodiments of the present application may be a mobile phone, a tablet computer, a desktop computer, a laptop computer, a handheld computer, a notebook computer, an ultra-mobile personal computer (UMPC), a cellular phone, a personal digital assistant (PDA), an augmented reality (AR) device, a virtual reality (VR) device, an artificial intelligence (AI) device, a wearable device, a vehicle-mounted device, a smart home device and / or a smart city device. The embodiments of the present application do not impose any special restrictions on the specific type of the electronic device.

[0053] The electronic device may include a housing, a processor, a battery, an antenna, a screen, an audio module, a speaker and other components. The wireless communication function of the electronic device may be realized by an antenna, a mobile communication module, a modulation and demodulation processor and a baseband processor. At the same time, the antenna of the electronic device may include an NFC antenna, which is an antenna using near field communication technology and is used to transmit and receive electromagnetic wave signals, thereby realizing the NFC communication function.

[0054] The embodiment of the present application defines the coordinate system of the accompanying drawings. The x-direction, y-direction, and z-direction are perpendicular to each other. The z-direction can be understood as the thickness direction of the electronic device, the y-direction can be understood as the width direction of the electronic device, and the x-direction can be understood as the length direction of the electronic device, or the y-direction can be understood as the length direction of the electronic device, and the x-direction can be understood as the width direction of the electronic device. Exemplarily, in the embodiment of the present application, the setting of the NFC antenna is described by taking the y-direction as the length direction of the electronic device and the x-direction as the width direction of the electronic device as an example.

[0055] Figure 1 This is a schematic diagram of a design method for an NFC antenna.

[0056] Figure 1The figure shows a dual-end design of an NFC antenna around a metal decorative part, in which the NFC antenna 130 is arranged near the camera decorative part 110. Specifically, the electronic device 100 may include a camera decorative part 110, a camera 120, an NFC antenna 130 and a back cover 140. The camera decorative part 110 is used to decorate the camera 120, the camera decorative part 110 and the NFC antenna 130 are both installed on the back cover 140, and the projection of the NFC antenna along the z direction is outside the projection range of the camera decorative part along the z direction, that is, the NFC antenna 130 bypasses the camera decorative part 110 and occupies the space outside the camera decorative part 110.

[0057] More specifically, the camera decorative part 110 may include a non-metallic appearance part 111 and a metal decorative part 112, wherein the non-metallic appearance part 111, the metal decorative part 112 and the NFC antenna 130 are stacked along the z direction, the metal decorative part 112 is located between the non-metallic appearance part 111 and the NFC antenna 130, and the NFC antenna 130 is disposed on the mainboard bracket of the mainboard of the electronic device. It can be understood that the projection of the non-metallic appearance part 111 along the z direction is within the range of the projection of the metal decorative part 112 along the z direction, and the projection of the NFC antenna 130 along the z direction is outside the range of the projection of the metal decorative part 112 along the z direction.

[0058] This NFC antenna design method may have the following disadvantages: First, as the size of camera trims of current electronic devices continues to increase, and the number of cameras continues to increase, when the NFC antenna is set on the outside of the camera trim, it will be affected by the size of the camera trim, resulting in insufficient placement of the NFC antenna, which makes the NFC antenna very close to the frame antenna, affecting the performance of the NFC antenna and the performance of other surrounding antennas. Second, as the size of camera trims continues to increase, when the NFC antenna is routed around the camera trim, there may be a small card reading blind spot at the center of the camera trim, affecting the user experience. Third, the NFC antenna is generally attached to the motherboard bracket of the motherboard, so when designing the NFC antenna, it is also necessary to place the motherboard bracket on the motherboard, which increases the overall thickness and weight of the electronic device, and does not take advantage of the thinning of the electronic device. Therefore, Figure 1 The NFC antenna design shown cannot meet the development requirements of electronic devices.

[0059] Figure 2 This is a schematic diagram of another design method for NFC antenna.

[0060] Figure 2The figure shows a single-end design of an NFC antenna, that is, a single-end design of an NFC antenna with a reused metal frame. In this design, the NFC antenna 230 is arranged on the frame 240. Specifically, the electronic device 200 may include a camera decoration 210, a camera 220, an NFC antenna 230, a frame 240 and a back cover 250. More specifically, the camera decoration 210 may include a non-metallic appearance part 211 and a metal decoration part 212. The camera decoration 110 is used to decorate the camera 120; the non-metallic appearance part 211 and the metal decoration part 212 are both installed on the back cover 250, and the projection of the non-metallic appearance part 211 along the z direction is within the range of the projection of the metal decoration part 212 along the z direction; the NFC antenna 230 is arranged on the frame 240, and the main screen antenna in the frame 240 is reused.

[0061] When this NFC antenna design method is used, since the NFC antenna uses a single-ended NFC antenna solution that reuses the metal frame, the NFC antenna may be limited by the design, structure, and antenna environment of the main screen antenna when in use. In addition, the NFC antenna design is also limited by the metal grounding position, branch length, and antenna clearance, etc., especially when the branch length is small and the clearance environment is poor, the NFC antenna performance is poor. Therefore, Figure 2 The NFC antenna design shown cannot meet the development requirements of electronic devices.

[0062] In order to solve the above technical problems, an embodiment of the present application provides a shell assembly and an electronic device, which can improve the performance of the NFC antenna while being suitable for large-sized camera decorations.

[0063] Figure 3 and Figure 4 It is a schematic diagram of a shell assembly provided in an embodiment of the present application.

[0064] The housing assembly may include a back cover 20, a camera decoration 30 and an NFC antenna 40, wherein the camera decoration 30 and the NFC antenna 40 are both mounted on the back cover 20, and the NFC antenna 40 is attached to the camera decoration 30. The projection of the NFC antenna 40 along a first direction is within the projection range of the camera decoration 30 along the first direction, and the first direction is the thickness direction of the electronic device.

[0065] Alternatively, if Figure 3As shown, the camera decorative part 30 is a non-metallic appearance part. In this case, the NFC antenna 40 can be set between the non-metallic appearance part and the back cover 20, and the NFC antenna 40 can be attached to the non-metallic appearance part. In other words, the projection of the NFC antenna 40 along the first direction is within the projection range of the non-metallic appearance part along the first direction. The specific setting position of the NFC antenna 40 can be referred to Fig. 9 In this case, the NFC antenna 40 does not occupy the space outside the camera decoration 30 and is thus not affected by the size of the camera decoration 30 .

[0066] Optionally, the camera decoration 30 may include a first decoration 310 and a second decoration 320, the first decoration 310 is arranged on a side of the second decoration 320 away from the back cover 20, and the NFC antenna 40 may be arranged within the projection coverage of the camera decoration 30, that is, the projection of the first decoration 310 along the first direction is within the projection range of the second decoration 320 along the first direction, and the projection of the NFC antenna 40 along the first direction is within the projection range of the second decoration 320 along the first direction. In this case, the NFC antenna 40 may be partially located outside the projection area formed by the first decoration 310 along the first direction, but is entirely located within the projection area formed by the second decoration 320 along the first direction, so that the NFC antenna 40 will not occupy the space outside the camera decoration 30, and will not be affected by the size of the camera decoration 30.

[0067] Alternatively, if Figure 4 As shown, the camera decoration 30 may include a first decoration 310 and a second decoration 320, the first decoration 310 is arranged on a side of the second decoration 320 away from the back cover 20, and the projection of the first decoration 310 along the first direction is located within the range of the projection of the second decoration 320 along the first direction, and the projection of the NFC antenna 40 along the first direction is located within the range of the projection of the first decoration 310 along the first direction. That is, the projection area of ​​the first decoration 310 coincides with the projection area of ​​the second decoration 320, and the projection area of ​​the NFC antenna 40 coincides with the projection area of ​​the first decoration 310. That is, the projection area of ​​the first decoration 310 along the xy plane is less than or equal to the projection area of ​​the second decoration 320 along the xy plane, and the projection area of ​​the NFC antenna 40 along the xy plane is less than or equal to the projection area of ​​the first decoration 310 along the xy plane. In this case, the NFC antenna 40 will not occupy the space outside the first decoration 310, and will not be affected by the size of the camera decoration 30.

[0068] In a possible implementation, the first decorative member 310, the NFC antenna 40, and the second decorative member 320 are stacked along the first direction, and the NFC antenna 40 is arranged between the first decorative member 310 and the second decorative member 320 to realize the NFC communication function of the electronic device. It should be understood that the NFC antenna 40 can be hidden between the first decorative member 310 and the second decorative member 320 by plating or coating. It should also be understood that the projection area of ​​the NFC antenna 40 coincides with the projection area of ​​the first decorative member 310, and the projection area of ​​the NFC antenna 40 also coincides with the projection area of ​​the second decorative member 320. That is, the projection area of ​​the NFC antenna 40 is inside the projection area of ​​the first decorative member 310, and the projection area of ​​the NFC antenna 40 is also inside the projection area of ​​the second decorative member 320. In other words, the projection area formed by the NFC antenna 40 along the xy plane is less than or equal to the projection area formed by the first decorative member 310 along the xy plane, and the projection area formed by the NFC antenna 40 along the xy plane is also less than or equal to the projection area formed by the second decorative member 320 along the xy plane.

[0069] Optionally, the NFC antenna 40 may be attached to a side of the first decorative member 310 close to the back cover 20 .

[0070] Optionally, the NFC antenna 40 may also be attached to a side of the second decorative member 320 away from the rear cover 20. The specific location of the NFC antenna 40 may refer to Fig.10 .

[0071] In another possible implementation, when the second decorative member 320 is partially injection molded, the NFC antenna 40 can be designed below or above the injection molding structure. That is, the second decorative member 320 includes a metal part and a non-metal part, the first decorative member 310, the second decorative member 320, and the NFC antenna 40 are stacked along the first direction, and the second decorative member 320 is located between the first decorative member 310 and the NFC antenna 40. In other words, along the first direction, the projection area of ​​the NFC antenna 40 overlaps with the projection area of ​​the first decorative member 310, and the projection area of ​​the NFC antenna 40 also overlaps with the projection area of ​​the second decorative member 320. That is, the projection area of ​​the NFC antenna 40 along the xy plane is less than or equal to the projection area of ​​the first decorative member 310 along the xy plane, and the projection area of ​​the NFC antenna 40 along the xy plane is also less than or equal to the projection area of ​​the second decorative member 320 along the xy plane.

[0072] Optionally, the NFC antenna 40 may be attached to a side of the non-metal portion of the second decorative member 320 away from the back cover 20 .

[0073] Optionally, the NFC antenna 40 may also be attached to a side of the non-metallic portion of the second decorative member 320 close to the back cover 20. The specific location of the NFC antenna 40 may refer to Fig.11 .

[0074] It is understandable that the first decorative element 310 may be made of non-metallic material, such as glass, ceramic, etc., and the second decorative element 320 may be made of metal. The non-metallic part of the second decorative element 320 is obtained by injection molding.

[0075] The NFC antenna in the embodiment of the present application does not need to bypass the camera decoration, that is, the NFC antenna will not occupy the space outside the camera decoration, and will not be affected by the size of the camera decoration. At the same time, because the NFC antenna is located on the inside of the camera decoration, the antenna clearance environment is good, and will not affect the performance of the NFC antenna and other surrounding antennas. In addition, the problem of the blind spot of reading small cards under large-sized camera decorations can also be solved, thereby increasing the user experience.

[0076] Optionally, the NFC antenna 40 may be composed of three NFC antennas of different designs. In the embodiment of the present application, the number of NFC antennas is not limited, and three NFC antennas are used as an example here. It should be understood that the present application may also include more NFC antennas (i.e., the number of antennas is greater than three) or fewer NFC antennas (i.e., the number of antennas is less than three).

[0077] It should be understood that the NFC antenna 40 can be formed by combining a flexible printed circuit (FPC) and a ferrite. That is, the NFC antenna 40 can include a flexible printed circuit (FPC) antenna and a ferrite, and the ferrite is used to isolate the FPC antenna from the second decorative piece 320, that is, the ferrite can reduce the influence of the metal decorative piece on the FPC antenna, and the ferrite can be arranged on the side of the FPC antenna close to the rear cover 20.

[0078] In some embodiments, the housing assembly further includes a magnetic isolation sheet, which is used to isolate the magnetism of the ferrite. The magnetic isolation sheet can be laid in the interference area of ​​the camera 50 to reduce the influence of the magnetism of the ferrite on the camera 50. Optionally, the magnetic isolation sheet can be arranged around the camera 50. Optionally, the magnetic isolation sheet can be attached between the ferrite and the second decorative member 320, that is, along the first direction, the magnetic isolation sheet can be arranged on the side of the second decorative member 320 close to the first decorative member 310, the ferrite can be arranged on the side of the magnetic isolation sheet close to the first decorative member 310, and the FPC can be arranged on the side of the ferrite close to the first decorative member 310. Optionally, the magnetic isolation sheet can also be attached below the second decorative member 320, that is, along the first direction, the magnetic isolation sheet can be arranged on the side of the second decorative member 320 away from the first decorative member 310, the ferrite can be arranged on the side of the second decorative member 320 close to the first decorative member 310, and the FPC can be arranged on the side of the ferrite close to the first decorative member 310.

[0079] It should be understood that in the embodiment of the present application, the NFC antenna 40 can be treated with a waterproof and dustproof edging process, that is, the NFC antenna 40 is obtained by a waterproof and dustproof process. Optionally, the ferrite can be treated with a polyester film (PET) waterproof edging process, and the FPC can be treated with a monomer waterproof process, so that the NFC antenna 40 is made outside the waterproof ring of the second decorative part 320. In other words, the FPC antenna and the ferrite are respectively obtained by a waterproof and dustproof process, wherein the FPC antenna is obtained by a separate waterproof process, and the ferrite is obtained by a polyethylene terephthalate plastic PET film waterproof edging process.

[0080] In addition, the NFC antenna 40 can be used in a camera decoration with a planar structure or a camera decoration with a partially micro-curved surface. The NFC antenna can be partially micro-curved and expanded. When the camera decoration is designed as a 3D non-planar structure, that is, when a non-planar structure appears inside the camera decoration, the corresponding NFC antenna cannot remain on the same plane, and a corresponding 3D NFC antenna needs to be designed. The NFC antenna design method will be combined with Figure 6 and Figure 7 The details are explained in detail and will not be repeated here.

[0081] It can be understood that along the first direction (i.e., along the z direction), the projection of the NFC antenna 40 does not overlap with the projection of the camera 50, and the camera 50 can be set within the coverage of the camera decoration 30, and further, the camera 50 can be set within the coverage of the first decoration 310. That is, the electronic device includes the camera 50, and when the housing assembly is installed on the electronic device, the projection of the NFC antenna 40 along the first direction does not overlap with the projection of the camera 50 along the first direction. When the NFC antenna 40 overlaps with the projection of the second decoration 320 and does not overlap with the projection of the camera 50, the NFC antenna 40 will not block the camera 50, thereby ensuring that the camera 50 can shoot normally.

[0082] It should be noted that the embodiment of the present application involves a two-terminal solution of NFC antenna design, that is, both ends of the NFC antenna 40 can be directly electrically connected to the mainboard of the electronic device through local punching, that is, directly fed to the mainboard of the electronic device. In other words, the NFC antenna 40 has at least one feeding point, and the projection of the at least one feeding point along the first direction is located inside the projection area of ​​the camera decorative part 30 along the first direction, and the at least one feeding point is electrically connected to the mainboard of the electronic device. Therefore, the NFC antenna design method provided in the embodiment of the present application does not need to set a mainboard bracket on the mainboard of the electronic device, thereby reducing the overall thickness and weight of the electronic device, and taking advantage of the thinning of the electronic device.

[0083] Figure 5 It is a schematic diagram of the NFC antenna design method provided in the embodiment of the present application.

[0084] Figure 5 Four feasible NFC antenna design methods are shown exemplarily. It should be understood that: Figure 5 This is only an example and should not limit the design of the NFC antenna in this application. Figure 5 As shown, illustratively, the NFC antenna can be arranged inside the coverage of the first decorative member 310, that is, the projection of the NFC antenna along the first direction is located within the projection range of the first decorative member 310 along the first direction. In other words, the projection area formed by the NFC antenna on the xy plane is less than or equal to the projection area formed by the first decorative member 310 on the xy plane, and the projection area formed by the NFC antenna on the xy plane is also less than or equal to the projection area formed by the second decorative member 320 on the xy plane. The NFC antenna does not need to bypass the second decorative member 320, that is, the NFC antenna will not occupy the space outside the second decorative member 320, and thus will not be affected by the size of the second decorative member 320.

[0085] Figure 5 (a) shows that the NFC antenna 41 bypasses four cameras and the NFC antenna routing is designed from the periphery of the camera; Figure 5(b) shows that the NFC antenna 42 bypasses a camera, and the NFC antenna routing is designed around the camera; Figure 5 (c) shows that the NFC antenna 43 bypasses two cameras, and the NFC antenna routing is designed around the two cameras; Figure 5 (d) shows that the NFC antenna 44 bypasses three cameras, and the NFC antenna routing is designed around the three cameras. In the embodiment of the present application, when the NFC antenna routing needs to be designed, it can be based on Figure 4 Four NFC antenna design methods are shown to set the antenna routing.

[0086] It is understandable that in Figure 4 The housing assembly shown is Figure 5 The NFC antenna design shown in (a) Figure 5 The NFC antenna design shown in (b) and Figure 5 The NFC antenna design shown in (d) in FIG.

[0087] It should be understood that the embodiment of the present application does not limit the shape of the camera decoration 30, the number of cameras 50, the arrangement of the cameras 50, the height of the cameras 50, and the routing of the NFC antenna 40.

[0088] It should also be understood that since the embodiment of the present application involves a two-terminal solution for the NFC antenna design, that is, both ends of the NFC antenna 40 can be directly electrically connected to the electronic device motherboard through local drilling. Therefore, when setting the opening of the NFC antenna, the NFC antenna should avoid the camera 50 and the opening of the related camera module, and the NFC antenna line width and the NFC antenna shape can also be adjusted according to the number and size of the openings.

[0089] Figure 6 and Figure 7 This is a schematic diagram of another shell assembly structure provided in an embodiment of the present application. Figure 6 and Figure 7 It is shown that the camera decoration 30 is designed as a 3D non-planar structure. When a non-planar structure appears inside the camera decoration 30, for example, when there are two or more planes inside the camera decoration 30, the corresponding NFC antenna 40 cannot be kept on the same plane, and the NFC antenna 40 also needs to be designed as a non-planar structure. Figure 6 or Figure 7 The specific location of the corresponding NFC antenna 40 can be referred to Fig.12 , Fig.12 It also shows Figure 6 or Figure 7 A cross-sectional diagram of the camera trim in FIG.

[0090] like Figure 6 or Figure 7 The housing assembly shown may include a back cover 20, a camera decoration 30 and an NFC antenna 40, wherein the camera decoration 30 and the NFC antenna 40 are both mounted on the back cover 20, and the NFC antenna 40 is attached to the camera decoration 30. The projection of the NFC antenna 40 along a first direction is within the projection range of the camera decoration 30 along the first direction, and the first direction is the thickness direction of the electronic device.

[0091] Optionally, the camera decorative part 30 may be a non-metallic appearance part. In this case, the NFC antenna 40 may be disposed between the non-metallic appearance part and the back cover 20, and the NFC antenna 40 may be attached to the non-metallic appearance part. In other words, the projection of the NFC antenna 40 along the first direction is within the range of the projection of the non-metallic appearance part along the first direction.

[0092] Optionally, the camera decoration 30 may include a first decoration 310 and a second decoration 320, the first decoration 310 is arranged on a side of the second decoration 320 away from the back cover 20, and the projection of the first decoration 310 along the first direction is within the range of the projection of the second decoration 320 along the first direction, and the projection of the NFC antenna 40 along the first direction is within the range of the projection of the first decoration 310 along the first direction.

[0093] In a possible implementation, the first decorative piece 310, the NFC antenna 40, and the second decorative piece 320 are stacked along a first direction, and the NFC antenna 40 is disposed between the first decorative piece 310 and the second decorative piece 320 to implement the NFC communication function of the electronic device. It should be understood that the NFC antenna 40 can be hidden between the first decorative piece 310 and the second decorative piece 320 by plating or coating.

[0094] Optionally, the NFC antenna 40 may be attached to a side of the first decorative member 310 close to the back cover 20 .

[0095] Optionally, the NFC antenna 40 may also be attached to a side of the second decorative component 320 away from the back cover 20 .

[0096] In another possible implementation, when the second decorative piece 320 is partially injection molded, the NFC antenna 40 can be designed below or above the injection molded structure. That is, the second decorative piece 320 includes a metal part and a non-metal part, the first decorative piece 310, the second decorative piece 320, and the NFC antenna 40 are stacked along the first direction, and the second decorative piece 320 is located between the first decorative piece 310 and the NFC antenna 40.

[0097] Optionally, the NFC antenna 40 may be attached to a side of the non-metal portion of the second decorative member 320 away from the back cover 20 .

[0098] Optionally, the NFC antenna 40 may also be attached to a side of the non-metallic portion of the second decorative component 320 close to the back cover 20 .

[0099] It is understandable that the first decorative element 310 may be made of non-metallic material, and the second decorative element 320 may be made of metallic material. The non-metallic part of the second decorative element 320 is obtained by injection molding.

[0100] It should be understood that the NFC antenna 40 can be formed by combining a flexible printed circuit (FPC) and a ferrite. That is, the NFC antenna 40 can include a flexible printed circuit (FPC) antenna and a ferrite, and the ferrite is used to isolate the FPC antenna from the second decorative piece 320, that is, the ferrite can reduce the influence of the metal decorative piece on the FPC antenna, and the ferrite can be arranged on the side of the FPC antenna close to the rear cover 20.

[0101] In some embodiments, the housing assembly further includes a magnetic isolation sheet, which is used to isolate the magnetism of the ferrite. The magnetic isolation sheet can be laid in the interference area of ​​the camera 50 to reduce the influence of the magnetism of the ferrite on the camera 50. The position setting of the magnetic isolation sheet can refer to Figure 3 or Figure 4 .

[0102] It should be understood that in the embodiment of the present application, the NFC antenna 40 can be treated with a waterproof and dustproof edging process, that is, the NFC antenna 40 is obtained by a waterproof and dustproof process. Optionally, the ferrite can be treated with a polyester film (PET) waterproof edging process, and the FPC can be treated with a monomer waterproof process, so that the NFC antenna 40 is made outside the waterproof ring of the second decorative part 320. In other words, the FPC antenna and the ferrite are respectively obtained by a waterproof and dustproof process, wherein the FPC antenna is obtained by a separate waterproof process, and the ferrite is obtained by a polyethylene terephthalate plastic PET film waterproof edging process.

[0103] It is understandable that along the first direction (i.e., along the z direction), the projection of the NFC antenna 40 does not overlap with the projection of the camera 50. That is, the electronic device includes a camera, and when the housing assembly is installed on the electronic device, the projection of the NFC antenna 40 along the first direction does not overlap with the projection of the camera 50 along the first direction. When the NFC antenna 40 overlaps with the projection of the second decorative member 320 and does not overlap with the projection of the camera 50, the NFC antenna 40 will not block the camera 50, thereby ensuring that the camera 50 can shoot normally.

[0104] It should be noted that the embodiment of the present application involves a two-terminal solution of the NFC antenna design, that is, both ends of the NFC antenna 40 can be directly electrically connected to the mainboard of the electronic device through local punching, that is, directly fed to the mainboard of the electronic device. In other words, the NFC antenna 40 has at least one feeding point, the projection of the at least one feeding point along the first direction is located inside the projection area of ​​the camera decorative part 30 along the first direction, and the at least one feeding point is electrically connected to the mainboard of the electronic device.

[0105] Since the NFC antenna 40 is originally produced as a planar NFC trace, it is necessary to process the NFC antenna 40 through a bending process so that the shape tolerance meets the second decorative component assembly and flatness requirements. That is, when the camera decorative component 30 can be a non-planar structure, the NFC antenna 40 is a non-planar structure obtained through a bending process or a welding process to adapt to the camera decorative component 30. Figure 6 As shown, the projection of the NFC antenna 40 completely overlaps with that of the second decorative piece, that is, the 3D structure of the NFC antenna 40 after being bent and fixed can match the shape of the second decorative piece, and can then be fixed by waterproof adhesive and positioning holes.

[0106] When the second decorative piece 320 has an irregular shape, the NFC antenna 40 cannot absorb the bending redundancy after the bending process, and welding is required at the bending position. That is, when the camera decorative piece 30 is a non-planar structure, the NFC antenna 40 can be a non-planar structure obtained by the bending process and the welding process to adapt to the camera decorative piece 30. Figure 7 As shown, at the welding point 410, the NFC antenna 40 is attached to the second decorative piece 320 of different shapes through the welding process and the pad design. It should be noted that when welding, it is necessary to control the welding impedance and thickness to reduce the performance loss of the NFC antenna caused by the impedance. Optionally, when the welding impedance accounts for less than 50% of the overall impedance of the NFC antenna, the performance loss of the NFC antenna is small.

[0107] The NFC antenna in the embodiment of the present application does not need to bypass the camera decoration, that is, the NFC antenna will not occupy the space outside the camera decoration, and will not be affected by the size of the camera decoration. Since the NFC antenna is located on the inner side of the camera decoration, the antenna clearance environment is good, and will not affect the performance of the NFC antenna and the performance of other surrounding antennas. In addition, the problem of blind spots for reading small cards under large-sized camera decorations can also be solved, thereby increasing the user experience. In addition, there is no need to set a motherboard bracket on the main board of the electronic device, and the overall thickness and weight of the electronic device can also be reduced, which can take advantage of the thinning of the electronic device. At the same time, when the camera decoration is designed as a non-planar structure, the NFC antenna can be made to fit camera decorations of various structures through a bending process and / or a welding process.

[0108] Figure 8 It is a schematic diagram of an electronic device provided in an embodiment of the present application.

[0109] like Figure 8 As shown, the electronic device may include a camera 50 and Figure 3 , Figure 4 , Figure 6 and Figure 7 The housing assembly described in any one of the above, and the camera decoration in the housing assembly can be used to decorate the camera. Specifically, the electronic device may include a mainboard 10, a back cover 20, a camera decoration 30, an NFC antenna 40 and a camera 50, and the mainboard 10 can be electrically connected to the NFC antenna 40.

[0110] Optionally, along the first direction (i.e., along the z direction), the projection of the NFC antenna 40 does not overlap with the projection of the camera 50. That is, the electronic device includes a camera, and when the housing assembly is installed on the electronic device, the projection of the NFC antenna 40 along the first direction does not overlap with the projection of the camera 50 along the first direction. When the NFC antenna 40 overlaps with the projection of the second decorative member 320 and does not overlap with the projection of the camera 50, the NFC antenna 40 will not block the camera 50, thereby ensuring that the camera 50 can shoot normally. At the same time, the camera 50 can be set within the coverage of the camera decorative member 30, and the camera 50 can also be set within the coverage of the first decorative member 310. The camera decorative member 30 and the first decorative member 310 can protect the camera 50 and prevent the camera 50 from being contaminated.

[0111] Optionally, a camera lens (not shown in the figure) is installed on the camera 50, and the camera 50 corresponds to the camera lens and can shoot the external environment through the camera lens.

[0112] It should be understood that a circuit layer is provided on the mainboard 10 , and the NFC antenna 40 and the camera 50 are electrically connected to the circuit layer on the mainboard 10 respectively.

[0113] It should be noted that the embodiment of the present application involves a two-terminal solution of NFC antenna design, that is, both ends of the NFC antenna 40 can be directly electrically connected to the mainboard of the electronic device through local punching, that is, directly fed to the mainboard of the electronic device. In other words, the NFC antenna 40 has at least one feeding point, and the projection of the at least one feeding point along the first direction is located inside the projection area of ​​the camera decorative part 30 along the first direction, and the at least one feeding point is electrically connected to the mainboard of the electronic device. Therefore, the NFC antenna design method provided in the embodiment of the present application does not need to set a mainboard bracket on the mainboard of the electronic device, thereby reducing the overall thickness and weight of the electronic device, and taking advantage of the thinning of the electronic device.

[0114] It should also be understood that when the two ends of the NFC antenna 40 are partially perforated through the second decorative piece 320, the perforated positions may be treated with waterproof glue.

[0115] In the electronic device provided in the embodiment of the present application, the NFC antenna does not need to bypass the camera decoration, that is, the NFC antenna will not occupy the space outside the camera decoration, and will not be affected by the size of the camera decoration. And because the NFC antenna is located on the inner side of the camera decoration, the antenna clearance environment is good, so it will not affect the performance of the NFC antenna and the performance of other surrounding antennas. In addition, the problem of blind spots for reading small cards under large-sized camera decorations can also be solved, which can increase the user experience. In addition, the NFC antenna can be directly fed to the motherboard of the electronic device, so there is no need to set a motherboard bracket on the main board of the electronic device, which can reduce the overall thickness and weight of the electronic device, and utilize the thinning of the electronic device. At the same time, when the camera decoration is designed as a non-planar structure, the NFC antenna can be made to fit camera decorations of various structures through a bending process and / or a welding process.

In other words, the NFC antenna 40 can be located between the camera decoration 30 and the back cover 20. And along the first direction, the projection area of ​​the NFC antenna 40 coincides with the projection area of ​​the camera decoration 30, that is, the projection area formed by the NFC antenna 40 along the xy plane is less than or equal to the projection area formed by the camera decoration 30 along the xy plane.

[0119] In addition, along the first direction, the projection of the NFC antenna 40 does not overlap with the projection of the camera, that is, the NFC antenna 40 can surround the camera but will not block the camera, thereby ensuring that the camera can work normally.

[0120] It should be understood that a circuit layer is provided on the mainboard 10 , and the NFC antenna 40 and the camera are electrically connected to the circuit layer on the mainboard 10 respectively.

[0121] It should be noted that the embodiment of the present application involves a two-terminal solution of NFC antenna design, that is, both ends of the NFC antenna 40 can be directly electrically connected to the mainboard of the electronic device through local punching, that is, directly fed to the mainboard of the electronic device. In other words, the NFC antenna 40 has at least one feeding point, and the projection of the at least one feeding point along the first direction is located inside the projection area of ​​the camera decorative part 30 along the first direction, and the at least one feeding point is electrically connected to the mainboard of the electronic device. Therefore, the NFC antenna design method provided in the embodiment of the present application does not need to set a mainboard bracket on the mainboard of the electronic device, thereby reducing the overall thickness and weight of the electronic device, and taking advantage of the thinning of the electronic device.

[0122] It should also be understood that when the two ends of the NFC antenna 40 are partially punched through the back cover 20 to the main board 10, the punched positions can be treated with waterproof glue.

The projection of the first decorative member 310 along the first direction is within the projection range of the second decorative member 320 along the first direction, and the projection of the NFC antenna 40 along the first direction is within the projection range of the first decorative member 310 along the first direction.

[0126] In addition, along the first direction, the projection of the NFC antenna 40 does not overlap with the projection of the camera, that is, the NFC antenna 40 can surround the camera but will not block the camera, thereby ensuring that the camera can work normally.

[0127] In a possible implementation, the second decorative member 320 is embedded in the back cover 20 , that is, the second decorative member 320 and the back cover 20 are located on the same horizontal plane.

[0139] Fig.12 It is a cross-sectional schematic diagram of another electronic device along the xz plane provided in an embodiment of the present application.

[0140] like Fig.12 As shown, Fig.12The figure shows a cross-sectional schematic diagram of another electronic device along the z direction, and the electronic device may include a first decorative member 310, a second decorative member 320, an NFC antenna 40, a back cover 20 and a main board 10.
