[0028] The following will be combined with the attached examples of the present application Figure 1 To Attachment Fig.15 , the technical solutions in the embodiments of the present application are clearly and completely described. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present application.

[0029] The present application embodiment provides a housing assembly 100 and an electronic device. Figure 1 and Figure 2 , Figure 1 This is a schematic diagram of a first structure of a housing assembly 100 provided in an embodiment of the present application. Figure 2 for Figure 1 The first electrical connection schematic diagram of the housing assembly 100 is shown. The housing assembly 100 includes a carbon fiber rear shell 110 and one or more conductor sheets 120 .

[0030] The carbon fiber back shell 110 includes a first portion 111 and a second portion 112. A first gap 113 is also formed on the carbon fiber back shell 110. The first gap 113 is formed between the first portion 111 and the second portion 112. The first gap 113 is located between the first portion 111 and the second portion 112. The first portion 111 may be located on one side of the first gap 113, and the second portion 112 may be located on the other side of the first gap 113. The first portion 111 may be spaced apart from the second portion 112, and the first gap 113 may insulate the first portion 111 from the second portion 112. The conductor sheet 120 is stacked on one side of the carbon fiber back shell 110 along the thickness direction H1 of the carbon fiber back shell 110. For example, the conductor sheet 120 may be disposed on the side of the carbon fiber back shell 110 close to the display surface of the electronic device. Figure 2 As shown, the conductor sheet 120 can be directly or indirectly electrically connected to the signal source 200 , and the conductor sheet 120 can be coupled to the first part 111 under the action of the excitation signal provided by the signal source 200 , so that the first part 111 supports the transmission and reception of wireless signals.

[0031] It is understandable that if Figure 1 As shown, the first portion 111, the first gap 113 and the second portion 112 may form a concentric ring structure from the inside to the outside, and the first gap 113 may be an annular gap structure connected end to end, for example, the first gap 113 may be, but not limited to, a rectangular ring structure, a circular ring structure or an irregular ring structure. The first portion 111 may be located inside the annular region enclosed by the first gap 113, and the second portion 112 may be located outside the annular region enclosed by the first gap 113.

[0032] Of course, if Figure 3 As shown, Figure 3 The second structural schematic diagram of the shell assembly 100 provided in the embodiment of the present application, the two ends of the first gap 113 may also be unconnected so that the first gap 113 is not an annular gap structure, for example, the first gap 113 may be an arc gap structure that is not connected at the head and tail, a bent gap structure that is not connected at the head and tail, etc. At this time, the first part 111 may be located on the side of the first gap 113 away from the second part 112, and the second part 112 may be located on the side of the first gap 113 away from the first part 111. It should be noted that the above is only an exemplary description of the arrangement layout of the first part 111, the second part 112 and the first gap 113 in the embodiment of the present application, and other solutions that can insulate the first part 111 and the second part 112 from each other are also within the protection scope of the embodiment of the present application.

[0033] It is understandable that the signal source 200 may be a radio frequency transceiver of an electronic device. The signal source may convert a high-frequency excitation current or bound electromagnetic wave into radiated electromagnetic energy to excite a radiating device such as the first part 111 to support wireless signal transmission; at the same time, the radiating device such as the first part 111 may also capture and bind electromagnetic waves in free space and transmit them to the signal source 200 to form a current signal, so that the radiating device such as the first part 111 may support the reception of wireless signals.

[0034] It is understood that the carbon fiber rear shell 110 is a shell structure made of carbon fiber composite materials. During the preparation process, carbon fiber filaments and materials such as resins, adhesives, and additives can be chemically or physically prepared into a single-layer carbon fiber structure layer or a multi-layer (two or more layers) carbon fiber structure layer, and then the multi-layer carbon fiber structure layer can be formed into a whole through lamination, injection molding, and other processes to prepare the carbon fiber rear shell 110. Among them, the carbon fiber rear shell 110 has the advantages of light weight, scratch resistance, anti-slip, and excellent heat dissipation.

[0035] It can be understood that, since carbon fiber is a conductive material, the carbon fiber back shell 110 is also conductive, so that the first part 111 separated by the first gap 113 on the carbon fiber back shell 110 is also conductive, and the first part 111 can be used as a radiation device to realize the wireless communication function of the housing assembly 100 and the electronic device 10 under the excitation of the excitation signal. For example, under the excitation of the signal source 200, the first part 111 can support the transmission of wireless fidelity (Wireless Fidelity, referred to as Wi-Fi) signals, global positioning system (Global Positioning System, referred to as GPS) signals, third-generation mobile communication technology (3rd-Generation, referred to as 3G), fourth-generation mobile communication technology (4th-Generation, referred to as 4G), fifth-generation mobile communication technology (5th-Generation, referred to as 5G), near field communication (Near field communication, referred to as NFC) signals, Bluetooth (Blue tooth, referred to as BT) signals, near field communication (Near Field Communication, referred to as NFC) signals, ultra-wideband communication (Ultra WideBand, referred to as UWB) signals, etc. The embodiment of the present application is not limited to this.

[0036] It can be understood that the first slit 113 can penetrate the carbon fiber rear shell 110 along the thickness direction H1 of the carbon fiber rear shell 110, so that the first part 111 can be separated from the second part 112 by the first slit 113. The second part 112 can serve as the main body of the carbon fiber rear shell 110, and the first part 111 can serve as a separate radiator to support the transmission and reception of wireless signals.

[0037] It can be understood that, in theory, the larger the slit width of the first slit 113, the easier it is for the wireless signal supported by the first part 111 to radiate to the free space, and the better the radiation performance of the first part 111. For example, the slit width of the first slit 113 may be greater than or equal to 0.2 mm. In order to ensure the consistency of the appearance of the carbon fiber back shell 110, the slit width of the first slit 113 may be smaller, so that the wireless signal supported by the first part 111 can be radiated from the first slit 113 to the free space, and the first slit 113 may not affect the appearance of the carbon fiber back shell 110. Optionally, the slit width of each first slit 113 may be greater than or equal to 0.2 mm and less than or equal to 0.5 mm. It should be noted that a non-conductive material can be filled in the first slit 113 to ensure the structural strength of the carbon fiber back shell 110.

[0038] It can be understood that the conductor sheet 120 can be used as a feeding connector of the first part 111. Under the action of the excitation signal provided by the signal source 200, the conductor sheet 120 can be coupled with the first part 111 to provide the excitation signal to the first part 111. Among them, the conductor sheet 120 can be connected and electrically connected to the first part 111 (or a partial area of ​​the first part 111) to provide the excitation signal to the first part 111, and the conductor sheet 120 can also be capacitively coupled with the first part 111 (or a partial area of ​​the first part 111) and provide the excitation signal to the first part 111. The so-called capacitive coupling means that when an electric field is generated between two conductors (for example, the conductor sheet 120 and the first part 111), the signal on one conductor can be transmitted to the other conductor through the electric field, so that the two conductors can also achieve electrical signal conduction without direct contact or direct connection.

[0039] The shell assembly 100 of the embodiment of the present application has a first slit 113 on the carbon fiber rear shell 110, so that the first part 111 and the second part 112 of the carbon fiber rear shell 110 are relatively independent, and the first part 111 can be used as an independent conductor structure. Under the action of the conductor sheet 120, the first part 111 can support the transmission and reception of wireless signals. Based on this, the shell assembly 100 of the embodiment of the present application uses the first part 111 of the carbon fiber rear shell 110 as a radiation device, and the first part 111 is reused, which can reduce the device stacking of the shell assembly 100 and the electronic device 10, and realize the miniaturization design of the shell assembly 100 and the electronic device 10; and the first part 111 is fed through the conductor sheet 120, and the feeding of the first part 111 is more reliable, which can ensure the radiation performance of the first part 111.

[0040] Please combine Figure 1 Please also refer to Figure 4 , Figure 4 A third structural schematic diagram of a housing assembly provided in an embodiment of the present application. One or more first gaps 113 may be formed on the carbon fiber rear housing 110, so that one or more first portions 111 may be formed on the carbon fiber rear housing 110. The housing assembly 100 may further include one or more conductor sheets 120.

[0041] The number of the first parts 111 may be equal to the number of the first slits 113. When a plurality of first slits 113 are provided on the carbon fiber rear shell 110 to form a plurality of first parts 112, each first part 112 may be insulated from other parts of the carbon fiber rear shell 110. At this time, one second part 112 may be formed on the carbon fiber rear shell 110, or a plurality of second parts 112 may be formed, and the number of the second parts 112 may be equal to or less than the number of the first parts 111. The embodiment of the present application does not limit the number of the second parts 112.

[0042] It can be understood that when the shell assembly 100 may include multiple conductor plates 120, the number of multiple conductor plates 120, multiple first gaps 113, and multiple first parts 111 can be equal, so that each first gap 113 corresponds to a first part 111 and a conductor plate 120, each first part 111 can be insulated from all second parts 112 and other first parts 111, and each first part 111 can be electromagnetically coupled with a conductor plate 120, and a first gap 113, a first part 111 and a first conductor plate 120 can form a group of radiation structures 101 to realize the wireless communication function of the first part 111. Among them, any two groups of radiation structures 101 can be spaced and insulated from each other to avoid mutual interference between different first parts 111 in different radiation structures 101. For example, Figure 1As shown, the housing assembly 100 may include a group of radiation structures 101; for example, Figure 4 As shown, the housing assembly 100 may include two groups of radiation structures 101 .

[0043] It is understandable that when the housing assembly 100 includes multiple groups of radiating structures 101, the multiple groups of radiating structures 101 can be electrically connected to the same signal source 200 and support the transmission and reception of wireless signals in the same frequency band or different frequency bands (for example, achieved through a combiner or splitter). Alternatively, the multiple groups of radiating structures 101 can also be electrically connected to different signal sources 200 and support the transmission and reception of wireless signals in the same frequency band or different frequency bands. This embodiment of the application is not limited to this.

[0044] It can be understood that when the shell assembly 100 includes multiple groups of radiation structures 101, the distance between any two first parts 111 in the multiple groups of radiation structures 101 can be greater than the preset distance, so that the isolation between the two first parts 111 when supporting wireless signals meets the requirements, and the interference between the two first parts 111 when supporting wireless signals is small; for example, the isolation between the two first parts 111 when supporting wireless signals can be greater than 15dB. Alternatively, any two first parts 111 in the multiple groups of radiation structures 101 can also support the transmission and reception of wireless signals of different frequency bands, so that the interference between wireless signals of different frequency bands is small. Alternatively, any two first parts 111 in the multiple groups of radiation structures 101 can be arranged in an orthogonal manner, so that when the two first parts 111 support wireless signals, orthogonal polarization radiation can be formed, so that when the two first parts 111 support wireless signals, the interference between the two first parts 111 is small. Of course, the layout of the multiple groups of radiation structures 101 can also adopt the above-mentioned methods at the same time, and the embodiments of the present application are not limited to this.

[0045] It is understandable that at least one conductor sheet 120 can be arranged at a small distance from the carbon fiber rear shell 110 on one side of the carbon fiber rear shell 110, and at least one conductor sheet 120 can also be connected to the carbon fiber rear shell 110 on one side of the carbon fiber rear shell 110 so that the distance between the conductor sheet 120 and the carbon fiber rear shell 110 is zero. The embodiment of the present application does not limit the specific arrangement of the conductor sheet 120, and any method that can make the conductor sheet 120 electromagnetically coupled with the first part 111 under the action of the excitation signal provided by the signal source 200 is within the protection scope of the embodiment of the present application.

[0046] It is understandable that at least one conductor sheet 120 can be, but is not limited to, a graphite sheet or a copper sheet. When the conductor sheet 120 is a graphite sheet, in addition to realizing the feeding function of the first part 111, the conductor sheet 120 can also realize the heat dissipation of the heat source (for example, but not limited to the circuit board 600 and the battery 700 of the electronic device 10), so that the shell assembly 100 of the embodiment of the present application has better heat dissipation performance. It should be noted that when the shell assembly 100 includes multiple conductor sheets 120, the multiple conductor sheets 120 can be of the same material structure, and at least two conductor sheets 120 can also be of different material structures; and at least one conductor sheet 120 can also be other conductor structures, which is not limited in the embodiment of the present application.

[0047] It is understandable that when the housing assembly 100 includes a plurality of conductor sheets 120, the plurality of conductor sheets 120 may be located on the same side of the carbon fiber rear shell 110, for example, the plurality of conductor sheets 120 may all be located on the side of the carbon fiber rear shell 110 close to the display surface of the electronic device 10, in which case the plurality of conductor sheets 120 are more easily electrically connected to the signal source 200 inside the electronic device 10. Of course, at least two of the plurality of conductor sheets 120 may also be located on different sides of the carbon fiber rear shell 110, in which case different electrical connection methods may be designed so that at least the conductor sheets 120 on different sides are all electrically connected to the signal source 200.

[0048] The shell assembly 100 of the embodiment of the present application has one or more first gaps 113 on the carbon fiber rear shell 110, so that each first part 111 of the carbon fiber rear shell 110 and each first part 111 can be relatively independent from the second part 112, and the first part 111 can be used as an independent conductor structure, and the first part 111 can support the transmission and reception of wireless signals under the action of the conductor sheet 120. Based on this, the shell assembly 100 of the embodiment of the present application uses the first part 111 of the carbon fiber rear shell 110 as a radiation device, and the first part 111 is reused, which can reduce the device stacking of the shell assembly 100 and the electronic device 10, and realize the miniaturization design of the shell assembly 100 and the electronic device 10; and the first part 111 is fed through the conductor sheet 120, and the feeding of the first part 111 is more reliable, which can ensure the radiation performance of the first part 111.

[0049] Please refer again to Figures 1 to 4 The projection of each conductor sheet 120 on the carbon fiber rear shell 110 may be located within the preset area 102 of the carbon fiber rear shell 110 , so that the first portion 111 generates a resonant current in the same direction under the action of the excitation signal.

[0050] It is understandable that although the carbon fiber filaments are conductive materials, due to the limitation of the preparation process, the carbon fiber rear shell 110 is not necessarily an integral conductor structure. Figure 5 and Figure 6 , Figure 5 for Figure 1 The first structural schematic diagram of the carbon fiber rear shell 110 is shown in FIG. Figure 6 for Figure 1 The second structural schematic diagram of the carbon fiber rear shell 110 is shown. Figure 5 As shown, the carbon fiber rear shell 110 may include a single-layer carbon fiber structure layer 103, and multiple carbon fiber filaments of the single-layer carbon fiber structure layer 103 may be formed into a layered structure by weaving, bonding, etc., and the multiple fiber filaments may be connected or not connected. Figure 6 As shown, the carbon fiber rear shell 110 may include at least two carbon fiber structural layers 103, and two adjacent carbon fiber structural layers 103 may be orthogonally stacked so that the multiple carbon fiber structural layers 103 may be tightly combined into a whole; however, due to limitations of the preparation process, non-conductive resins, glue and other structures may exist between the multiple carbon fiber structural layers 103, which may make some parts of the multiple carbon fiber structural layers 103 connected and some parts may not be connected.

[0051] It is understandable that when the projection of the conductor sheet 120 on the carbon fiber rear shell 110 is located within the preset area 102 of the carbon fiber rear shell 110, the conductor sheet 120 can make the carbon fiber structural layer 103 of the first part 111 form a conductor as a whole. The first part 111 generates a resonant current in the same direction under the action of the excitation signal.

[0052] It can be understood that the preset area 102 can be in the area formed by the first slit 113 and the first part 111 in the same radiation structure 101 as the conductor sheet 120, and the difference between the first dimension of the preset area 102 along the length direction H2 of the carbon fiber rear shell 110 and the second dimension of the first part 111 along the length direction H2 is not less than one eighth of the corresponding wavelength of the wireless signal supported by the first part 111 in the radiation structure 101, and the difference between the third dimension of the preset area 102 along the width direction H3 of the carbon fiber rear shell 110 and the third dimension of the first part 111 along the width direction H3 is not less than one eighth of the corresponding wavelength of the wireless signal supported by the first part 111 in the radiation structure 101. The projection of each conductor sheet 120 of the housing assembly 100 on the carbon fiber rear shell 110 can be located in the area formed by the first slit 113 and the first part 111 in the same radiation structure 101 corresponding to the conductor sheet 120.

[0053] It can be understood that the difference between the first dimension of the projection of the conductor sheet 120 on the carbon fiber rear shell 110 along the length direction H2 of the carbon fiber rear shell 110 and the second dimension of the first part 111 (the first part 111 in the same radiation structure 101 as the conductor sheet 120) along the length direction H2 of the carbon fiber rear shell 110 is not less than one eighth of the wavelength corresponding to the wireless signal supported by the first part 111 in the radiation structure 101. That is, the difference between the first dimension and the second dimension is greater than or equal to one eighth of the wavelength. In addition, the difference between the third dimension of the projection of the conductor sheet 120 on the carbon fiber rear shell 110 along the width direction H3 of the carbon fiber rear shell 110 and the fourth dimension of the first part 111 (the first part 111 in the same radiation structure 101 as the conductor sheet 120) along the width direction H3 of the carbon fiber rear shell 110 is not less than one eighth of the wavelength corresponding to the wireless signal supported by the first part 111 in the radiation structure 101. That is, the difference between the third dimension and the fourth dimension is greater than or equal to one eighth of the wavelength. At this time, the conductor sheet 120 can be disposed opposite to the first portion 111 in the same radiation structure 101 , and the area of ​​the conductor sheet 120 is equivalent to the area of ​​the first portion 111 , so that the first portion 111 is not prone to reverse current distribution.

[0054] For example, please refer to Figure 7 , Figure 7 for Figure 2 As shown in the first current schematic diagram of the shell assembly 100, under the excitation of the signal source 200, the conductor sheet 120 can form a strong coupling with the first part 111, and the strong coupling can make the carbon fiber structural layer 103 of the first part 111 conductive as a whole. The conductor sheet 120 can make the first part 111 generate a resonant current in the same direction under the action of the excitation signal of the signal source 200, and the first part 111 can have better antenna radiation performance.

[0055] For comparison, see Figure 8 and Fig. 9 , Figure 8 for Figure 1 The second electrical connection schematic diagram of the housing assembly 100 is shown in FIG. Fig. 9 for Figure 8 A current schematic diagram of the housing assembly 100 is shown. When the signal source 200 is directly electrically connected to the first portion 111 of the carbon fiber rear shell 110 to achieve feeding, since the carbon fiber rear shell 110 is not a completely connected conductor structure, the carbon fiber rear shell 110 will generate a reverse resonant current under the action of the excitation signal, and the reverse resonant current will affect the normal operation of the first portion 111 of the carbon fiber rear shell 110 as a radiation device, resulting in poor radiation performance of the first portion 111.

[0056] For example, please refer to Fig.10 , Fig.10for Figure 2 The housing assembly 100 is shown with Figure 8 The S parameter curve comparison diagram of the housing assembly 100 is shown. Fig.10 The middle curve S1 is Figure 2 The S parameter curve when the first part 111 of the housing assembly 100 is fed through the conductor sheet 120 is shown in FIG. Figure 8 The S parameter curve when the first part 111 of the shell assembly 100 is not fed through the conductor sheet 120. When the first part 111 works at 1.8 GHz, it can be seen from the curve S2 that when the first part 111 is not fed through the conductor sheet 120, more reverse resonant currents are formed on the first part 111, so that the first part 111 forms more spurious resonances (such as area A and area B on the curve S2), which seriously affects the radiation performance of the first part 111. In contrast, it can be seen from the curve S1 that when the first part 111 is fed through the conductor sheet 120 and the projection of the conductor sheet 120 on the carbon fiber rear shell 110 is located in the preset area 102 of the carbon fiber rear shell 110, a resonant current in the same direction can be formed on the first part 111, the first part 111 can resonate near 1.8 GHz, and no spurious resonance is generated in other frequency bands. The first part 111 has better radiation performance, which can ensure the antenna performance of the first part 111.

[0057] It can be understood that the shape of the conductor sheet 120 in the embodiment of the present application can be adapted to the shape of the first part 111, and the shape of the conductor sheet 120 can also be different from the shape of the first part 111; the conductor sheet 120 and the first part 111 can be but are not limited to being rectangular, long strips, or bent shapes, and the embodiment of the present application does not limit the specific shapes and structures of the conductor sheet 120 and the first part 111.

[0058] The embodiment of the present application proposes an antenna solution that can be applied to a carbon fiber back shell 110. The first part 111, which is a carbon fiber radiator, is separated from the other part of the carbon fiber back shell 110, the second part 112, by a first gap 113. A conductor sheet 120 of the same size as the first part 111 is closely attached to the first part 111 below the first part 111, which can ensure that the resonant current on the first part 111 is in the same direction, so that there is no clutter when the first part 111 supports wireless signals, and the first part 111 can have better radiation performance. In addition, when the housing assembly 100 is assembled with other structures of the electronic device 10, the first part 111 has the maximum clearance performance, which can further improve the radiation performance of the first part 111; at the same time, there is no need to open a large window on the carbon fiber back shell 110, which can ensure that the appearance of the carbon fiber back shell 110 is consistent, and the carbon fiber back shell 110 is more beautiful.

[0059] When the first part 111 is used as a carbon fiber radiator, the first part 111 can support the transmission of wireless signals in any antenna form. The first part 111 can be grounded or not grounded.

[0060] For example, refer again to Figures 1 to 10 , the first part 111 may be suspended relative to the ground plane 300, in which case the first part 111 may be spaced apart from the ground plane 300, the first part 111 may not be directly electrically connected to the ground plane 300, and the first part 111 is not grounded. It is understood that the ground plane 300 may be a plane or structure with zero potential, and the ground plane 300 may form a common ground. The ground plane 300 may be formed by a conductor, a printed circuit, or a metal printed layer in the electronic device 10.

[0061] For another example, see Fig.11 , Fig.11 for Figure 1 The third electrical connection schematic diagram of the housing assembly 100 is shown. The housing assembly 100 may further include a grounding member 130, one end of which may be electrically connected to the ground plane 300, and the other end of which may be directly or indirectly electrically connected to the conductor sheet 120, so as to achieve grounding of the first portion 111 of the radiation structure 101 in the same location as the conductor sheet 120.

[0062] For another example, please refer to Fig.12 , Fig.12 for Figure 1 The fourth electrical connection schematic diagram of the shell assembly 100 is shown. The grounding member 130 of the shell assembly 100 can be stacked on one side of the first part 111 along the thickness direction H1 of the carbon fiber rear shell 110, and the grounding member 130 can be coupled with the first part 111 to achieve grounding. In this embodiment, the grounding member 130 can be stacked on the same side of the first part 111 with the conductor sheet 120, and the grounding member 130 can be spaced apart from the conductor member. Of course, the grounding member 130 can also be stacked on different sides of the first part 111 with the conductor sheet 120. The specific setting method of the grounding member 130 is not limited in the embodiment of the present application.

[0063] It can be understood that the grounding member 130 can be but is not limited to a grounding spring, a grounding screw, a flexible circuit board structure, etc. Any structure that can achieve grounding conduction can be the grounding member 130 of the embodiment of the present application; the embodiment of the present application does not limit the specific structure of the grounding member 130.

[0064] It can be understood that the first part 111 can support the transmission and reception of wireless signals in the form of but not limited to a patch antenna, an inverted F antenna, a planar inverted F antenna or a T-shaped antenna. The embodiment of the present application does not limit the specific antenna form of the first part 111.

[0065] Among them, please refer to Fig.13 , Fig.13 This is a fourth structural schematic diagram of the housing assembly 100 provided in an embodiment of the present application. The carbon fiber rear housing 110 may further include a third portion 114 .

[0066] A second gap 115 may be formed between the third portion 114 and the second portion 112 . Under the action of the second gap 115 and the first gap 113 , the first portion 111 , the second portion 112 , and the third portion 114 may be insulated from each other.

[0067] like Fig.13 As shown, the first portion 111, the second portion 112 and the third portion 114 may form a concentric ring structure, the first portion 111 may be located inside the first gap 113, the second portion 112 may be located between the second gap 115 and the first gap 113, and the third portion 114 may be located outside the second gap 115. At this time, the first portion 111, the first gap 113, the second portion 112, the second gap 115 and the third portion 114 may be arranged in sequence from the inside to the outside.

[0068] It is understandable that the second gap 115 can be arranged close to the outer periphery of the carbon fiber rear shell 110, for example, the second gap 115 can be arranged within a range of 0.5 mm to 1.5 mm from the outer periphery of the carbon fiber rear shell 110. In this case, the third portion 114 can form an outer frame structure of the carbon fiber rear shell 110; the radiator structure inside the electronic device 10 can radiate signals outward through the second gap 115.

[0069] It is understandable that the gap size of the second gap 115 (here is the gap width size, the gap length size is not required) can be greater than or equal to 0.2 mm. In order not to affect the appearance of the carbon fiber back shell 110, the gap size of the second gap 115 can also be less than 0.5 mm.

[0070] It is understandable that the second gap 115 and the first gap 113 may be filled with a structure having a texture similar to that of the carbon fiber rear shell 110 , so as to increase the structural strength of the carbon fiber rear shell 110 and ensure the consistency of the appearance of the carbon fiber rear shell 110 .

[0071] It is understandable that the textures of the first portion 111 , the second portion 112 , and the third portion 114 may be designed so that when the first portion 111 , the second portion 112 , and the third portion 114 are integrated, the texture on the carbon fiber rear shell 110 may maintain continuity.

[0072] It is understandable that during the production process of the housing assembly 100, the carbon fiber rear shell 110 can be prepared first, and then the first gap 113 and the second gap 115 can be formed by etching, laser engraving, cutting, etc. Of course, the first part 111, the second part 112, and the third part 114 can also be prepared first, and then the three parts can be assembled into a structure with the first gap 113 and the second gap 115 spaced apart by injection molding or other assembly processes. The specific structure of the carbon fiber rear shell 110 is not limited in the embodiment of the present application.

[0073] It is understandable that the carbon fiber back shell 110 has a certain conductivity, which enables the carbon fiber back shell 110 to shield the antenna radiator inside the electronic device 10 and affect the radiation performance of the antenna radiator. When the electronic device 10 of the related art is provided with the carbon fiber back shell 110, it is necessary to hollow out part of the carbon fiber back shell 110 to serve as a radiation window for the antenna radiator inside the electronic device 10. However, the partial hollowing solution will make the appearance of the carbon fiber back shell 110 inconsistent, affecting the aesthetics of the carbon fiber back shell 110. The carbon fiber back shell 110 of the embodiment of the present application only has a first slit 113 and a second slit 115 with a smaller slit width on the shell, which can make the first part 111 support wireless signals and have better radiation performance, and can also not affect the radiation performance of the antenna radiator inside the electronic device 10, and can also ensure the consistency of the appearance of the carbon fiber back shell 110.

[0074] It should be noted that the above is only an exemplary description of the concentric rings formed by the first part 111, the second part 112 and the third part 114. The first part 111, the second part 112 and the third part 114 may also have other arrangements, and any solution that can achieve mutual insulation between the first part 111, the second part 112 and the third part 114 may be within the protection scope of the embodiment of the present application, and the embodiment of the present application does not limit this.

[0075] It should be noted that the above is only an exemplary description of the shell assembly 100 of the embodiment of the present application. For example, the carbon fiber back shell 110 may also reserve installation holes for functional modules such as a rear camera and a flash so that these functional modules can perform their functions.

A power management circuit may be provided on the circuit board 600.
