[0002] The electronic device includes components such as a housing, a battery, a screen and a camera, wherein the housing includes a back cover and a middle frame, and the screen is mounted on the housing and encloses a battery compartment for accommodating the battery. Usually, devices such as a camera and a flash are mounted on the back cover of the electronic device through a camera decoration, and the camera decoration and the battery compartment are arranged along the length direction of the electronic device. When the length of the camera decoration increases, the length of the battery compartment decreases, thereby reducing the capacity of the battery, which is not conducive to improving the battery life.

[0005] In the embodiment of the present application, in the camera decoration of the back cover assembly, the second mounting portion for mounting the functional device extends along the length direction of the electronic device to the top of the second accommodating cavity, so that the projection of the second mounting portion along the thickness direction of the electronic device covers a part of the second accommodating cavity for accommodating the battery, thereby increasing the length of the camera decoration, and this method does not cause the length of the second accommodating cavity for accommodating the battery to be reduced, which is conducive to increasing the capacity of the battery. The retaining wall of the middle frame extends along the thickness direction of the electronic device to support the back cover assembly, reducing the risk of the back cover assembly and the components (such as the main camera head and functional devices) mounted on the back cover assembly moving toward the inside of the accommodating cavity or deforming, thereby reducing the risk of damaging the components in the accommodating cavity, especially reducing the risk of the second mounting portion and the functional device mounted on the second mounting portion moving toward the second accommodating cavity or deforming, thereby reducing the risk of damaging the battery in the second accommodating cavity, and improving the reliability of the whole machine.

[0006] In a specific embodiment, the baffle wall is bonded to the back cover assembly, thereby further improving the supporting reliability of the baffle wall to the back cover assembly, further reducing the risk of the back cover assembly and functional devices installed on the back cover assembly moving toward the battery under the action of external force, and the adhesive bonding the back cover assembly and the baffle wall can also buffer the impact force between the baffle wall and the back cover assembly.

[0007] In a specific embodiment, the retaining wall has a first end surface supporting the rear cover assembly, and the dimension of the first end surface along the length direction of the electronic device is L1, 0.5mm≤L1≤1.5mm. In this embodiment, the contact area between the retaining wall and the rear cover assembly is moderate, so that the retaining wall has good support reliability for the rear cover assembly, and does not cause a significant reduction in the length of the first accommodating cavity and the second accommodating cavity.

[0008] In a specific embodiment, the baffle wall has a second end face arranged opposite to the first end face, and along the length direction of the electronic device, the size L1 of the first end face is larger than the size L2 of the second end face, thereby increasing the contact area between the baffle wall and the back cover assembly while reducing the overall weight and volume of the baffle wall, which is conducive to realizing lightweight electronic equipment.

[0009] In a specific embodiment, the functional device includes a base and a body mounted on the base, the base is mounted on the camera decorative piece; the back cover assembly also includes a support member, the support member is located between the body and the back cover, and is fixedly connected to the base. The support member can be used to support the functional device, improve the installation reliability of the camera decorative piece on the functional device, reduce the risk of the functional device moving toward the second accommodating cavity along the thickness direction of the electronic device under the action of external force, and thus reduce the risk of the functional device affecting the reliability of the battery in the second accommodating cavity.

[0010] In a specific embodiment, the support member and the base are bonded by adhesive, and the thickness of the adhesive is 0.15mm-0.3mm. In this embodiment, the adhesive can not only realize the fixed connection between the support member and the base, but also play a certain buffering role, that is, it can buffer the external force between the base and the support member, thereby reducing the external force acting on the body of the functional device through the support member, and improving the safety and service life of the body.

[0011] In a specific embodiment, the camera decoration is provided with a force release part. The stiffness of the force release part is less than the stiffness of the position of the camera decoration without the force release part, that is, the force release part is the position of the camera decoration that is most likely to deform when subjected to external force. Therefore, when the electronic device is subjected to external force on the camera decoration due to working conditions such as falling, the position of the force release part is deformed first under the action of the external force. The deformation of the force release part can dissipate the energy of the external force, thereby reducing the risk of deformation at other positions except the force release part, that is, reducing the risk of deformation at the position for installing the functional device, improving the installation reliability of the functional device, and reducing the risk of deformation of the functional device and the camera decoration in the direction toward the battery affecting the reliability of the battery.

[0012] In a specific embodiment, the force release portion is a groove provided in the camera decorative part. The thickness of the bottom wall of the groove is less than the thickness of other positions of the camera decorative part. When the camera decorative part is subjected to external force, the camera decorative part is more likely to deform at the position of the groove, thereby reducing the risk of deformation of the portion of the camera decorative part used to install the functional device when subjected to external force, thereby reducing the risk of deformation of the functional device installed on the camera decorative part toward the battery, affecting the reliability of the battery.

[0013] In a specific embodiment, the groove includes at least a first section extending along the length direction of the electronic device and a second section extending along the width direction of the electronic device. The first section and the second section can buffer the external force applied to the camera decoration in two directions, thereby further reducing the risk of deformation of the second mounting portion.

[0014] In a specific embodiment, the camera decoration is provided with a reinforcement portion, so as to enhance the overall structure of the camera decoration and improve the installation reliability of the camera decoration to the functional device.

[0015] In a specific embodiment, the camera decoration includes an inner decoration and an outer decoration; along the length direction of the electronic device, the edge of the outer decoration exceeds the edge of the inner decoration, and the outer decoration extends to the top of the second accommodating cavity, and the inner decoration is located in the first accommodating cavity. In this embodiment, when the camera decoration includes an outer decoration and an inner decoration, along the length direction of the electronic device, the length of the inner decoration is less than the length of the outer decoration, that is, a part of the outer decoration extends to the top of the first accommodating cavity along the length direction of the electronic device, and the inner decoration does not extend toward the second accommodating cavity, so it does not occupy the space of the second accommodating cavity, which is beneficial to increase the capacity of the battery and facilitate the realization of a large camera and high battery life for the electronic device.

[0016] In a specific embodiment, the outer decoration comprises a first outer decoration and a second outer decoration. Along the thickness direction of the electronic device, the first outer decoration is connected to the side of the second outer decoration away from the back cover; the second outer decoration is provided with a force release part and / or a reinforcement part. In this embodiment, the force release part can reduce the risk of deformation of the position of the second outer decoration for mounting the functional device, and the reinforcement part can increase the overall strength of the second outer decoration, thereby reducing the risk of the functional device moving toward the battery under the action of external force and affecting the reliability of the battery.

[0017] In a specific embodiment, along the length direction of the electronic device, there is a gap t between the inner decoration and the battery, 0.4 mm ≤ t ≤ 1 mm. In this embodiment, when 0.4 mm ≤ t ≤ 1 mm, the capacity of the battery can be maximized while preventing the inner decoration from contacting the battery.

[0018] A second aspect of an embodiment of the present application provides a back cover assembly, comprising a back cover and a camera decoration installed on the back cover, the camera decoration comprising a first mounting portion for mounting the camera and a second mounting portion for mounting a functional device, the second mounting portion extending in a length direction and capable of being located above a battery of the electronic device.

[0019] In the embodiment of the present application, in the camera decoration of the back cover assembly, the second mounting portion for mounting the functional device extends along the length direction of the electronic device, so that the projection of the second mounting portion along the thickness direction of the electronic device covers a part of the second accommodation cavity for accommodating the battery, thereby increasing the length of the camera decoration, and this method does not cause the length of the second accommodation cavity for accommodating the battery to be reduced, which is conducive to increasing the capacity of the battery. In addition, the support member can be used to support the functional device, improve the installation reliability of the camera decoration on the functional device, reduce the risk of the functional device moving toward the second accommodation cavity along the thickness direction of the electronic device under the action of external force, thereby reducing the risk of the functional device affecting the reliability of the battery in the second accommodation cavity.

[0020] The third aspect of the present application provides a rear cover assembly, the rear cover assembly includes a rear cover and a camera decoration installed on the rear cover, the camera decoration is provided with a force release part. The stiffness of the force release part is less than the stiffness of the position of the camera decoration where the force release part is not provided, that is, the force release part is the position of the camera decoration that is most likely to deform when subjected to external force. Therefore, when the rear cover assembly causes the camera decoration to be subjected to external force due to working conditions such as falling, the position of the force release part is deformed first under the action of the external force, and the deformation of the force release part can dissipate the energy of the external force, thereby reducing the risk of deformation at other positions except the force release part, that is, reducing the risk of deformation at the position for installing the functional device, improving the installation reliability of the functional device, and reducing the risk of deformation of the functional device and the camera decoration in the direction toward the battery that affects the reliability of the battery.

[0067] At present, the development direction of electronic devices is to be thinner and lighter and have a longer battery life, that is, the thickness of electronic devices is required to be smaller and smaller, and the capacity of batteries is required to be larger and larger. Under the premise that the thickness of electronic devices is small, it is necessary to increase the capacity of the batteries by increasing the length or width, and usually by increasing the length of the batteries. The electronic device also includes a camera decoration for installing a camera and its functional components. Usually, the camera decoration and the battery compartment for accommodating the battery are arranged along the length direction of the electronic device, and the two together occupy the space in the length direction of the electronic device. When the length of the camera decoration increases, the length of the battery compartment decreases, and when the length of the battery compartment increases, the length of the camera decoration decreases. Therefore, the arrangement of the camera decoration and the battery compartment of the existing electronic device cannot increase the size of the camera decoration and the battery at the same time.

[0068] In order to solve the above technical problems, the present application extends a part of the camera decoration for installing the camera and functional devices along the length direction of the electronic device, so that the projection of the camera decoration along the thickness direction of the electronic device covers a part of the battery compartment, thereby increasing the length of the camera decoration while not reducing the length of the battery compartment, that is, not reducing the capacity of the battery. At this time, the projection of the functional device installed on the camera decoration along the thickness direction of the electronic device overlaps with a part of the projection of the battery along the thickness direction. When the electronic device falls or other working conditions, there is a risk that the functional device and the camera decoration move toward the battery compartment, thereby there is a risk that the functional device or the camera decoration contacts the battery, resulting in a decrease in battery reliability. In the present application, the risk of the functional device and the camera decoration moving toward the battery when subjected to external force is reduced in a variety of ways, including but not limited to increasing the support reliability of the camera decoration for the functional device, buffering the external force on the camera decoration, and increasing the overall strength of the camera decoration.

[0069] In order to better understand the technical solution of the present application, the embodiments of the present application are described in detail below with reference to the accompanying drawings.

[0070] Figure 1 This is a schematic diagram of the structure of an electronic device provided in this application in a specific embodiment. Figure 2 for Figure 1 A part of the AA section view. Figure 1 and Figure 2 As shown, an embodiment of the present application provides an electronic device, which 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 netbook, and 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 embodiment of the present application does not impose any special restrictions on the specific type of the electronic device.

[0071] like Figure 1As shown, the electronic device includes components such as a housing, a battery, a mainboard, and a screen. The mainboard is used to control components such as the screen and the battery, and the battery is used to power components such as the screen and the mainboard. The housing includes a middle frame 14 and a back cover assembly, and the back cover assembly includes a back cover 11. The screen and the back cover 11 are mounted on both ends of the middle frame 14 along the thickness direction Z of the back cover assembly, and form a receiving cavity for accommodating components such as the battery and the mainboard. The thickness direction Z of the back cover assembly described in the embodiment of the present application is the same as the thickness direction of the electronic device.

[0072] The present application also provides a back cover assembly of an electronic device. Figure 3 for Figure 1 A partial view of the top view. Figure 3 As shown, the back cover assembly also includes a camera decoration 12 installed on the back cover 11, and the camera decoration 12 is used to install the camera of the electronic device (such as the main camera 5) and other related components. For example, the camera decoration 12 can also be used to install the functional device 4. Among them, the functional device 4 can be a flash, a micro camera, a laser focus device and other components. The functional device 4 can be a device with a weight less than the main camera 5, and the functional device 4 is installed on the side of the main camera 5 close to the battery.

[0073] like Figure 2 As shown, the middle frame 14, the back cover 11 and the screen enclose a first accommodating cavity 15 and a second accommodating cavity 16 distributed along the length direction X of the back cover assembly, wherein the first accommodating cavity 15 is used to accommodate components such as the motherboard of the electronic device, and the second accommodating cavity 16 is used to accommodate components such as the battery of the electronic device, that is, the second accommodating cavity 16 is the battery compartment described above. Generally, the size of the second accommodating cavity 16 along the length direction X of the back cover assembly is larger than the size of the first accommodating cavity 15 along the length direction X of the back cover assembly to maximize the capacity of the battery. Among them, the length direction X of the back cover assembly described in the embodiment of the present application is the same as the length direction X of the electronic device.

[0074] Combination Figure 2 and Figure 3 The camera decoration 12 includes a second mounting portion 122 for mounting the functional device 4 and a first mounting portion 121 for mounting the camera, and the first mounting portion 121 and the second mounting portion 122 are distributed along the length direction X of the rear cover assembly. Figure 2 and Figure 3In the illustrated embodiment, the second mounting portion 122 is the portion of the camera decoration 12 in the dotted line frame, and the first mounting portion 121 is the portion of the camera decoration 12 in the dotted line frame. The first mounting portion 121 may be a portion of the camera decoration 12 located above the first accommodating cavity 15, and the second mounting portion 122 may be a portion of the camera decoration 12 located above the second accommodating cavity 16, that is, the projection of the first mounting portion 121 along the thickness direction Z of the rear cover assembly falls into the first accommodating cavity 15; the projection of the second mounting portion 122 along the thickness direction Z of the rear cover assembly falls into the second accommodating cavity 16.

[0075] In summary, if Figure 2 and Figure 3 In the illustrated embodiment, in the rear cover assembly, the camera decoration 12 extends along the length direction X of the rear cover assembly, so that the second mounting portion 122 in the camera decoration 12 extends to above the second accommodating cavity 16 for accommodating the battery, thereby maximizing the length of the camera decoration 12 without reducing the length of the second accommodating cavity 16, thereby increasing the installation space of the camera and its functional components, which is beneficial to increasing the camera volume of the electronic device.

[0076] Among them, the second mounting portion 122 of the camera decoration 12 can be used to install a functional device 4 whose weight and volume are smaller than the main camera 5. The functional device 4 with smaller weight and volume has a lower risk of moving toward the battery when subjected to external force, thereby reducing the impact on battery reliability.

[0077] In order to further improve the reliability of the battery and reduce the risk of the camera decoration 12 and the functional device 4 applying external force to the battery and affecting the battery safety, one way is to increase the installation reliability of the camera decoration 12 to the functional device 4, which is described in detail below.

[0078] Figure 4 for Figure 1 Part of the cross-sectional view of the middle rear cover assembly along the AA direction, Figure 5 for Figure 4 In a specific embodiment, as Figure 5 As shown, the functional device includes a body 41 and a base 42, the base 42 has an installation space for accommodating the body 41, the functional device 4 is installed on the second installation portion 122 of the camera decorative member 12 through the base 42, and the base 42 is used to protect the body 41. The functional device 4 can be a flash. In a specific embodiment, the back cover assembly may also include a support member 13, which is located between the body 41 and the back cover 11 along the thickness direction Z of the back cover assembly, and the support member 13 is fixedly connected to the base 42 of the functional device 4.

[0079] Among them, Figure 5In the illustrated embodiment, the fixed connection between the support member 13 and the base 42 of the functional device 4 can be achieved through the adhesive 131, that is, the support member 13 and the base 42 are bonded through the adhesive 131, and the thickness of the adhesive 131 can be 0.15mm-0.3mm, for example, the thickness of the adhesive 131 can be 0.15mm, 0.18mm, 0.19mm, 0.2mm, 0.21mm, 0.25mm, 0.3mm, etc. In this embodiment, the adhesive 131 can not only achieve the fixed connection between the support member 13 and the base 42, but also play a certain buffering role, that is, it can buffer the external force between the base 42 and the support member 13, thereby reducing the external force acting on the body 41 of the functional device 4 through the support member 13, and improving the safety and service life of the body.

[0080] Figure 6 for Figure 2 A partial enlarged view of part I. Figure 5 and Figure 6 In a specific embodiment, along the thickness direction Z of the rear cover assembly, the support member 13 is located between the body 41 of the functional device 4 and the second accommodating cavity 16, that is, the support member 13 separates the body 41 of the functional device 4 from the battery in the second accommodating cavity 16. In this embodiment, the support member 13 can be used to support the functional device 4, improve the installation reliability of the camera decorative member 12 on the functional device 4, reduce the risk of the functional device 4 moving toward the second accommodating cavity 16 along the thickness direction Z of the rear cover assembly under the action of external force, and thus reduce the risk of the functional device 4 affecting the reliability of the battery in the second accommodating cavity 16. In addition, the support member 13 in this embodiment not only supports the body 41 of the functional device 4, but also extends to the bottom of the base 42 of the functional device 4 and is fixedly connected to the base 42, thereby supporting the body 41 and the base 42 of the functional device 4, thereby further improving the support reliability of the functional device 4, and then improving the installation reliability of the functional device 4 on the camera decorative member 12.

[0081] In another specific embodiment, please refer to Figure 7 and Figure 8 , Figure 7 for Figure 2 The front view of Figure 8 for Figure 7 A partial enlarged view of part III. Figure 7 and Figure 8As shown, the middle frame 14 may include a retaining wall 141, which is located between the first accommodating cavity 15 and the second accommodating cavity 16, and is used to separate the components in the first accommodating cavity 15 from the components in the second accommodating cavity 16, to prevent the components in the two accommodating cavities from contacting each other and causing defects such as short circuits. The retaining wall 141 extends along the thickness direction Z of the rear cover assembly, and is used to support the rear cover assembly, reducing the risk of the rear cover assembly and the components mounted on the rear cover assembly (such as the main camera 5 and the functional device 4) moving toward the inside of the accommodating cavity or deforming, thereby reducing the risk of damaging the components in the accommodating cavity. Figure 8 In the illustrated embodiment, when the second mounting portion 122 of the camera decoration 12 extends toward the second accommodating cavity 16, the retaining wall 141 supports the rear cover assembly, which can reduce the risk of the second mounting portion 122 and the functional device 4 installed on the second mounting portion 122 moving into the second accommodating cavity 16, thereby reducing the impact on the reliability of the battery located in the second accommodating cavity 16.

[0082] In a specific embodiment, the baffle wall 141 and the back cover assembly can be bonded to further improve the support reliability of the baffle wall 141 on the back cover assembly, further reduce the risk of the back cover assembly and the functional device 4 installed on the back cover assembly moving toward the battery under the action of external force, and the glue bonding the back cover assembly and the baffle wall 141 can also buffer the impact force between the baffle wall 141 and the back cover assembly.

[0083] Among them, Figure 6 In the embodiment shown, the bonding of the retaining wall 141 and the rear cover assembly may specifically be bonding of the retaining wall 141 and the rear cover 11. Figure 8 In the embodiment shown, the camera decoration 12 may include an outer decoration and an inner decoration 125, wherein the inner decoration 125 is located in the first accommodating cavity, the outer decoration is located outside the first accommodating cavity, and the inner decoration 125 and the inner decoration are both connected to the back cover 11. At this time, the retaining wall 141 may be bonded to the inner decoration 125.

[0084] In another specific embodiment, Figure 6 and Figure 8As shown, in the electronic device, a part of the structure of the camera decoration 12 for installing the functional device 4 extends along the length direction X to the top of the second accommodating cavity 16 for installing the battery, so that while increasing the length of the camera decoration, the length of the second accommodating cavity 16 will not be reduced, which is convenient for realizing a large camera and a long battery life of the electronic device. A support member 13 is arranged between the functional device 4 and the second accommodating cavity 16, and the support member 13 is connected to the base 42 of the functional device 4, so as to reduce the risk of the functional device 4 moving toward the second accommodating cavity 16 when subjected to external force, thereby reducing the risk of the battery reliability decreasing due to the movement of the functional device 4 toward the second accommodating cavity 16 when subjected to external force. At the same time, the retaining wall 141 of the middle frame 14 of the electronic device extends along the thickness direction Z of the rear cover assembly to abut against the rear cover assembly, so as to support the rear cover assembly through the retaining wall 141, thereby reducing the risk of the battery reliability decreasing due to the movement of the rear cover assembly toward the second accommodating cavity 16 when subjected to external force. Therefore, in this embodiment, under the support of the support member 13 and the retaining wall 141, the risk of battery reliability decreasing can be reduced.

[0085] In a specific embodiment, Figure 6 and Figure 8 As shown, the camera decoration may include an inner decoration 125 and an outer decoration (for example, at least a second outer decoration 124), and the outer decoration extends along the length direction X of the rear cover assembly to above the second accommodating cavity 16, that is, along the length direction X of the rear cover assembly, the edge of the outer decoration exceeds the edge of the inner decoration 125, so that while increasing the length of the camera decoration, the length of the second accommodating cavity 16 will not be reduced, which is convenient for realizing a large camera and a long battery life of the electronic device.

[0086] Fig. 9 It is a partial cross-sectional view of an electronic device provided in the present application in a specific embodiment. The retaining wall 141 has a first end face 141a abutting against the rear cover assembly, and the dimension L1 of the first end face 141a along the length direction X of the rear cover assembly satisfies: 0.5mm≤L1≤1.5mm. For example, L1 can be 0.5mm, 0.8mm, 0.9mm, 1mm, 1.1mm, 1.2mm, 1.5mm, etc.

[0087] In this embodiment, when L1 is too small, the contact area between the retaining wall 141 and the rear cover assembly is too small. When the rear cover assembly and / or the middle frame 14 is subjected to external force, the stress at the position where the first end surface 141a contacts the rear cover assembly is too large, and there is a risk of damage to the retaining wall 141. In addition, the support reliability of the retaining wall 141 to the rear cover assembly is poor, and there is a possibility that the battery reliability cannot be effectively reduced. When L1 is too large, the dimension occupied by the retaining wall 141 along the length direction X of the rear cover assembly is too large, thereby affecting the dimension of the first accommodating cavity 15 and the second accommodating cavity 16 along the length direction X. When 0.5mm≤L1≤1.5mm, the contact area between the retaining wall 141 and the rear cover assembly is moderate, so that the support reliability of the retaining wall 141 to the rear cover assembly is good, and the length of the first accommodating cavity 15 and the second accommodating cavity 16 will not be significantly reduced.

[0088] In a specific embodiment, Fig. 9 As shown, the baffle wall 141 also has a second end face 141b arranged opposite to the first end face 141a. Along the length direction X of the back cover assembly, the size L2 of the second end face 141b is smaller than the size L1 of the first end face 141a, thereby increasing the contact area between the baffle wall 141 and the back cover assembly while reducing the overall weight and volume of the baffle wall 141, which is conducive to achieving lightweight electronic equipment.

[0089] Specifically, along the thickness direction Z of the rear cover assembly and the direction from the screen to the rear cover assembly, the size of the retaining wall 141 along the length direction X of the rear cover assembly gradually increases, that is, the longitudinal cross-section of the retaining wall 141 can be an inverted trapezoidal structure.

[0090] In a specific embodiment, Fig. 9 As shown, the second receiving cavity of the electronic device contains a battery 6, and along the length direction X of the rear cover assembly, there is a gap t between the battery 6 and the interior decoration 125, and the gap t satisfies 0.4mm≤t≤1mm. For example, the gap t can be 0.4mm, 0.5mm, 0.55mm, 0.6mm, 0.8mm, 1mm, etc.

[0091] In this embodiment, when the gap t between the battery 6 and the inner decoration 125 is too small, there is a risk that the inner decoration 125 and the battery 6 may contact each other during the use of the electronic device, affecting the reliability of the battery. When the gap t between the battery 6 and the inner decoration 125 is too large, the size of the second accommodating cavity along the length direction X of the rear cover assembly is reduced, affecting the capacity of the battery 6. When 0.4 mm ≤ t ≤ 1 mm, the capacity of the battery 6 can be maximized while preventing the inner decoration 125 from contacting the battery 6.

[0092] Fig.10 for Figure 1 A schematic diagram of the partial structure of the back cover assembly in another perspective. Fig.10In the illustrated embodiment, a through hole 113 is provided at a position of the back cover for enclosing the second accommodating cavity 16, and the through hole 113 is used for the flexible circuit board 2 to pass through. One end of the flexible circuit board 2 is connected to the functional device 4, and the other end can extend into the first accommodating cavity 15 through the through hole 113 and be connected to the main board in the first accommodating cavity 15. The through hole 113 can be a structure adapted to the flexible circuit board 2, and a part of the flexible circuit board 2 is located in the through hole 113, that is, a part of the flexible circuit board 2 is embedded in the back cover 11, thereby preventing the flexible circuit board 2 from extending into the second accommodating cavity 16.

[0093] In a specific embodiment, Figure 5 and Figure 6 As shown, the electronic device may further include an isolation component 3, which is located between the second accommodating cavity 16 and the support member 13 along the thickness direction Z of the back cover assembly, thereby isolating the support member 13 from the battery in the second accommodating cavity 16. The isolation component 3 may be foam. Fig.10 When the through hole 113 is shown, the isolation component 3 covers at least a portion of the through hole 113, thereby isolating the flexible circuit board 2 located in the through hole 113 and the battery in the second accommodating cavity 16, thereby improving the reliability of the battery.

[0094] like Figure 8 In the illustrated embodiment, the insulating component 3 may include foam, which is located in the through hole and does not occupy the space outside the through hole, so that the volume of the second accommodating cavity 16 is not reduced due to the provision of the foam, which is beneficial to increase the capacity of the battery.

[0095] In a specific embodiment, Fig. 9 As shown, the insulating component 3 may also include graphite located between the functional device 4 and the battery, thereby isolating the functional device 4 from the battery.

[0096] In a specific embodiment, Fig.11 This is an exploded view of the back cover assembly provided in this application in a specific embodiment. Please refer to Figure 5 and Fig.11 The camera decoration 12 may include an outer decoration and an inner decoration 125. The inner decoration 125 is located on the inner side of the rear cover 11, that is, the inner decoration 125 surrounds the top wall of the first accommodating cavity 15 described above, and the outer decoration is located on the outer side of the rear cover 11. Along the thickness direction of the rear cover assembly, the inner decoration 125 and the outer decoration are located on both sides of the rear cover 11, and the outer decoration passes through the rear cover 11 and is connected to the inner decoration 125, thereby realizing the connection between the camera decoration 12 and the rear cover 11. Figure 5 and Fig.11In the illustrated embodiment, the inner decoration 125, the outer decoration and the rear cover 11 can be detachably connected by structures such as screws and buckles, and the connection method in which the inner decoration 125 and the outer decoration clamp the rear cover 11 has the advantage of high connection reliability.

[0097] Please combine Figure 5 and Figure 8 When the camera decoration includes an outer decoration and an inner decoration 125, along the length direction X of the rear cover assembly, the length of the inner decoration 125 is less than that of the outer decoration, that is, the outer decoration extends to the top of the first accommodating cavity 15 along the length direction X of the rear cover assembly, and the inner decoration 125 is used to enclose the first accommodating cavity 15, that is, the inner decoration 125 does not extend toward the second accommodating cavity 16, so it does not occupy the space of the second accommodating cavity 16, which is conducive to increasing the capacity of the battery. Figure 8 In the illustrated embodiment, the retaining wall 141 of the middle frame abuts against the inner decoration component 125 .

[0098] Among them, Fig.11 In the illustrated embodiment, the outer decorative component may further include a first outer decorative component 123 and a second outer decorative component 124 , wherein the second outer decorative component 124 is connected to the rear cover 11 , the first outer decorative component 123 is connected to the side of the second outer decorative component 124 facing away from the rear cover 11 , and the first outer decorative component 123 is used to protect the second outer decorative component 124 .

[0099] In other embodiments, the camera decoration may also include only an outer decoration without an inner decoration, and the outer decoration is fixedly connected to the outer side of the rear cover 11. The camera decoration in this embodiment has the advantage of a simple structure. Therefore, the present application does not limit the specific structure of the camera decoration.

[0100] In order to further improve the reliability of the battery and reduce the risk of camera decorations and functional devices applying external forces to the battery and affecting battery safety, another method is to reduce the deformation of the camera decoration at the location where the functional device is installed when subjected to external forces. This method is described in detail below.

[0101] The camera decoration is provided with a force release part, and the rigidity of the force release part is less than the rigidity of the position of the camera decoration without the force release part, that is, the force release part is the position of the camera decoration that is most likely to deform when subjected to external force. Therefore, when the electronic device is subjected to external force due to working conditions such as falling, the position of the force release part is deformed first under the action of the external force. The deformation of the force release part can dissipate the energy of the external force, thereby reducing the risk of deformation at other positions except the force release part, that is, reducing the risk of deformation at the position for installing the functional device, improving the installation reliability of the functional device, and reducing the risk of deformation of the functional device and the camera decoration in the direction of the battery affecting the reliability of the battery. The force release part with a smaller rigidity can be realized in the following ways: first, the elastic modulus of the material of the force release part is smaller than the elastic modulus of other positions of the camera decoration; second, the force release part is a groove provided in the camera decoration, and the thickness of the bottom wall of the groove is smaller than the thickness of the camera decoration at other positions.

[0102] In a specific embodiment, Fig.12 for Fig.11 Schematic diagram of the structure of the second outer decorative member in a specific embodiment. Fig.12 As shown, the second outer decorative member 124 is provided with a mounting hole 122a for mounting a functional device, wherein the mounting hole 122a extends to the top of the second accommodating cavity. The second outer decorative member 124 is provided with a groove 126, which is the force release portion described above. When the camera decorative member is subjected to external force, the second outer decorative member 124 is more likely to deform at the position of the groove 126 than at the position of the mounting hole 122a, thereby reducing the risk of deformation at the position of the mounting hole 122a when subjected to external force, thereby reducing the risk of the functional device installed in the mounting hole 122a being affected by deformation of the mounting hole 122a toward the battery, which affects the reliability of the battery.

[0103] like Fig.12 In the embodiment shown, the groove 126 at least includes a first section 126a extending along the length direction X of the rear cover assembly and a second section 126b extending along the width direction Y of the rear cover assembly. The first section 126a and the second section 126b can buffer the external force on the camera decorative part in two directions, thereby further reducing the risk of position deformation of the mounting hole 122a. The width direction Y of the rear cover assembly described in the embodiment of the present application is the same as the width direction of the electronic device.

[0104] Among them, the groove 126 in this embodiment can be a structure that penetrates the second outer decorative component 124 along the thickness direction, and when the second outer decorative component 124 is connected to the first outer decorative component 123, the first outer decorative component 123 can cover the groove 126, thereby maintaining the appearance integrity of the camera decorative component, giving it a good appearance effect, and reducing the risk of impurities entering through the groove 126.

[0105] In other embodiments, when the camera decoration is an integrated structure, the groove can be provided on the inner wall of the integrated camera decoration. Therefore, the present application does not limit the specific structure of the camera decoration.

[0106] In order to improve the reliability of the battery and reduce the risk of the camera decoration and functional devices exerting external forces on the battery that affect the battery safety, another way is to strengthen the overall structure of the camera decoration to improve the reliability of the camera decoration on the functional device. This method is described in detail below.

[0107] In a specific embodiment, Fig.13 for Fig.12 In this embodiment, the second outer decorative member 124 may be provided with a reinforcing portion 127, which is in a cross-shaped shape, thereby increasing the strength of the second outer decorative member 124 from all directions and reducing the risk of deformation thereof under the action of external force.

[0108] When the second outer decoration piece 124 is connected to the first outer decoration piece 123 , the first outer decoration piece 123 can cover the reinforcing portion 127 , so that the camera decoration piece has a good appearance.

[0109] In other embodiments, when the camera decoration is an integrated structure, the reinforcement portion 127 can be disposed on the inner wall of the integrated camera decoration. Therefore, the present application does not limit the specific structure of the camera decoration.

[0110] Fig.14 for Figure 1 A portion of a cross-sectional view taken along line AA of an electronic device in another specific embodiment, Fig.15 for Fig.14 A partial enlarged view of part IV.

[0111] Fig.14 and Fig.15 In the embodiment shown, the back cover 11 is not provided with a through hole at the position where the functional device 4 is installed, that is, the functional device 4 is separated from the second accommodating cavity 16 by the back cover 11, so that the risk of the functional device 4 entering the second accommodating cavity 16 and affecting the reliability of the battery when subjected to external force can be reduced by the back cover 11. Fig.14 and Fig.15The through hole through which the flexible circuit board (not shown) passes can be provided in the rear cover 11, and the flexible circuit board extends into the first accommodation cavity through the through hole provided in the rear cover 11, and is connected to the main board in the first accommodation cavity. In addition, when the camera decorative member 12 includes an inner decorative member 125, the inner decorative member 125 can also be provided with a through hole, so that the flexible circuit board extends into the first accommodation cavity through the through hole provided in the rear cover 11 and the through hole of the inner decorative member 125.

[0112] Fig.14 and Fig.15 In the embodiment shown, except that the rear cover 11 is not provided with a through hole, the other structures are the same as Figure 1-13 The structures of the embodiments shown are the same and will not be described again.

[0113] The above is only a specific implementation of the embodiment of the present application, but the protection scope of the embodiment of the present application is not limited thereto, and any changes or replacements within the technical scope disclosed in the embodiment of the present application should be included in the protection scope of the embodiment of the present application. Therefore, the protection scope of the embodiment of the present application should be based on the protection scope of the claims.
