DETAILED DESCRIPTION

[0032] Exemplary embodiments will be described in detail herein, examples of which are shown in the accompanying drawings. When the following description refers to the drawings, the same numbers in different drawings represent the same or similar elements unless otherwise indicated. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present disclosure. Instead, they are merely examples of devices and methods consistent with some aspects of the present disclosure as detailed in the appended claims.

[0033] At present, for example, when repairing an electronic device, it is necessary to disassemble the battery cover of the electronic device, and it is easy to cause damage to the battery when disassembling the battery cover. Exemplarily, the electronic device includes a middle frame and a battery cover provided on the back of the middle frame, and the battery cover is connected to the middle frame by gluing, and the battery cover and the middle frame form a receiving cavity, and the battery is arranged in the receiving cavity. When disassembling the battery cover, a disassembly sheet is usually used to extend between the battery cover and the middle frame to destroy the colloid between the two, thereby realizing the disassembly of the battery cover. However, the disassembly process is manual disassembly, and it is difficult to control the depth of the disassembly sheet extending between the battery cover and the middle frame during disassembly, and it is easy to extend the disassembly sheet into the receiving cavity to cause scratches, punctures and other damages to the battery. At present, the battery of the electronic device is usually a lithium-ion battery, which is very likely to cause safety accidents such as fire when damaged.

[0034] Based on this, the related art reduces the risk of damaging the battery by disassembling the electronic device by widening the side of the electronic device. This method not only wastes the overall space of the electronic device, which is not conducive to the miniaturization design of the electronic device, but also still has the risk of damaging the battery during disassembly. For example, Figure 1 As shown, the electronic device 1 in the related art includes a middle frame 11 and a battery cover 12 disposed on the back of the middle frame 11. The battery cover 12 is bonded to the middle frame 11 through an adhesive layer 15 to achieve connection with the middle frame 11. The battery cover 12 and the middle frame 11 form a receiving cavity 13, and the battery 10 is disposed in the receiving cavity 13.

[0035] When disassembling the battery cover 12, insert the disassembly sheet through the gap between the battery cover 12 and the middle frame 11 (such as Figure 1 In order to prevent the disassembly sheet from extending into the accommodating cavity 13, the side of the electronic device 1 is usually widened, that is, the distance from the side edge of the battery cover 12 of the electronic device 1 to the accommodating cavity 13 is increased (such as Figure 1 In this way, not only will the space of the electronic device 1 be wasted, which is not conducive to the miniaturization design of the electronic device 1, but there is still a risk of damaging the battery 10 when a longer disassembly piece is used to disassemble the battery cover 12.

[0036] In order to solve the above technical problems, the present disclosure provides a shell assembly in which the battery cover is arranged as two parts, namely, a body and a pressing part. The body cover is arranged on the back of the middle frame to form a receiving cavity with the middle frame, so that the edge of the body is placed on the frame of the middle frame, and the pressing part is connected to the frame and at least covers a part of the body located on the frame to fix the body on the middle frame. In this way, when disassembling the battery cover, the disassembly is carried out from the connection between the pressing part and the body, and the disassembly tool will not extend into the receiving cavity, so there is no possibility of damaging the battery, which improves the disassembly yield and safety during disassembly. At the same time, there is no need to change the size of the electronic device, which is conducive to the miniaturization design of the electronic device.

[0037] An exemplary embodiment of the present disclosure provides a housing assembly, such as Figure 2 , Figure 3 and Figure 4 As shown, the shell assembly includes a middle frame 11 and a battery cover 12. The battery cover 12 is configured to include a body 121 and a pressing portion 122. The body 121 is covered on the back of the middle frame 11 to form a receiving cavity 13 with the middle frame 11. Exemplarily, the middle frame 11 includes a support plate 111 and a frame 112 arranged on each edge of the support plate 111. Usually, the support plate 111 is a rectangular plate-like structure with four edges, and four frames 112 are correspondingly arranged. Each frame 112 and the support plate 111 are enclosed together to form a groove-like structure. The body 121 is covered on the back of the middle frame 11 to block the opening of the groove-like structure to form a closed cavity. The cavity constitutes the receiving cavity 13, and the battery 10 of the electronic device 1 is arranged in the receiving cavity 13. It can be understood that the back of the middle frame 11 refers to the side surface opposite to the screen module of the electronic device 1.

[0038] The edge of the body 121 is placed on the frame 112 of the middle frame 11. For example, the edge of the body 121 can be placed on the back of the middle frame 11 located on the frame 112, or a groove matching the edge of the body 121 can be provided on the frame 112, and the edge of the body 121 is placed in the groove of the frame 112. The pressing part 122 is connected to the frame 112 and at least covers a part of the body 121 located on the frame 112. For example, part of the pressing part 122 is connected to the frame 112, and the other part of the pressing part 122 covers at least a part of the body 121 located on the frame 112. For example, it can only cover a part of the body 121 placed on the frame 112; it can also cover the entire structure of the body 121 placed on the frame 112; it can also cover the part of the body 121 located at the accommodating cavity 13 while covering the entire structure of the body 121 placed on the frame 112. Here, there is no specific limitation on the range of the pressing part 122 covering the body 121. The body 121 is fixed to the middle frame 11 by the pressing part 122. For example, the pressing part 122 can be connected to the frame 112 by gluing, snapping, etc., and the pressing part 122 can also be connected to the body 121 by gluing, snapping, etc. when covering the body 121.

[0039] With such a design, when the battery cover 12 needs to be disassembled, it is disassembled from the connection between the pressing portion 122 and the main body 121, and the disassembly tool will not extend into the accommodating cavity 13, so there is no possibility of damaging the battery 10, thereby improving the disassembly yield and safety during disassembly. At the same time, there is no need to change the size of the electronic device 1, which is conducive to the miniaturized design of the electronic device 1.

[0040] Combination Figure 4In one embodiment, the surface of the pressing part 122 facing the frame 112 includes a first connecting surface 1226 and a second connecting surface 1227 connected to each other. The first connecting surface 1226 is connected to the frame 112, and the connection method can be, for example, adhesive bonding, clamping, etc. A first avoidance structure is provided in the area corresponding to the pressing part 122 on the body 121, and part of the pressing part 122 extends into the avoidance space formed by the first avoidance structure, that is, the area corresponding to the second connecting surface 1227 on the pressing part 122 partially extends into the avoidance space, and is connected to the first avoidance structure through the second connecting surface 1227, and the connection method can be, for example, adhesive bonding, clamping, etc., so that the body 121 and the frame 112 are fixed. With such a setting form, the pressing part 122 can be embedded in the body 121 to reduce the thickness of the shell assembly, thereby facilitating the thinning design of the electronic device 1. It can be understood that the thickness of the shell assembly refers to the thickness of the shell assembly in a direction perpendicular to the back of the shell assembly.

[0041] In one embodiment, a second avoidance structure is provided in the area of ​​the pressing part 122 corresponding to the main body 121, and the second avoidance structure is spliced ​​with the first avoidance structure, so that the surface of the pressing part 122 facing away from the frame 112 can be flush with the outer surface of the main body 121. With such a design, on the one hand, the tightness of the connection between the pressing part 122, the main body 121 and the frame 112 can be improved, thereby improving the stability of the main body 121 when it is fixed to the frame 112. On the other hand, by splicing the first avoidance structure with the second avoidance structure, the surface of the pressing part 122 facing away from the frame 112 is flush with the outer surface of the main body 121, which can not only further reduce the thickness of the shell assembly, but also effectively improve the flatness of the back of the shell assembly, thereby helping to improve the aesthetic appearance of the electronic device 1. It is understandable that a portion of the back side of the body 121 (i.e., the side surface of the body 121 facing away from the accommodating cavity 13) is covered by the pressing portion 122, and the portion of the back side of the body 121 not covered by the pressing portion 122 is the outer surface of the body 121.

[0042] Combination Figure 4 and Figure 5In one embodiment, the body 121 includes a first step surface 1211, a second step surface 1212 and a first surface 1213 connected in sequence, the first step surface 1211 is connected to the outer surface of the body 121, and the first step surface 1211 and the second step surface 1212 constitute a first avoidance structure. The pressing portion 122 includes a second surface 1221, a third step surface 1222, a fourth step surface 1223 and a third surface 1224 connected in sequence, and the third step surface 1222 and the fourth step surface 1223 constitute a second avoidance structure. The second surface 1221 constitutes a first connecting surface 1226, and the first connecting surface 1226 is opposite to the frame 112 and connected to the frame 112. The third step surface 1222 is opposite to the first surface 1213 and is in contact with the first surface 1213. The fourth step surface 1223 constitutes a second connection surface 1227, the second connection surface 1227 is opposite to and connected to the second step surface 1212, and the third surface 1224 is opposite to and fits the first step surface 1211. In this way, the first avoidance structure is spliced ​​with the second avoidance structure, so that the body 121 is fixed to the frame 112, and the tightness of the connection between the pressing part 122, the body 121 and the frame 112 is improved, thereby improving the stability of the body 121 when it is fixed to the frame 112.

[0043] Combination Figure 4 In one embodiment, the first connection surface 1226 is bonded to the frame 112, and the second connection surface 1227 is bonded to the second step surface 1212, so that the body 121 is fixed to the frame 112 through the pressing portion 122. With such a setting, the connection between the pressing portion 122 and the frame 112 and the body 121 is simple, which can improve the assembly efficiency of the housing assembly.

[0044] When the battery cover 12 needs to be disassembled, a disassembly tool such as a disassembly sheet can be used to disassemble the battery cover 12 from the connection between the pressing portion 122 and the body 121 (such as Figure 4 D shown in the figure, extends between the first step surface 1211 of the main body 121 and the third surface 1224 of the pressing part 122, and then continues to extend between the second step surface 1212 of the main body 121 and the second connecting surface 1227 of the pressing part 122 to destroy the adhesive layer 15 (for example, double-sided tape) between the second step surface 1212 and the second connecting surface 1227. Continue to extend along the extending direction, after passing between the first surface 1213 of the main body 121 and the third step surface 1222 of the pressing part 122, extend to between the first connecting surface 1226 of the pressing part 122 and the frame 112 to destroy the adhesive layer 15 (for example, double-sided tape) between the first connecting surface 1226 and the frame 112, thereby achieving the disassembly of the battery cover 12. In the above-mentioned disassembly process, the extending direction of the disassembly tool (such as Figure 4The battery cover 12 is moved away from the accommodating cavity 13 (the direction indicated by the dotted arrow shown in the figure), so that when the battery cover 12 is disassembled, the disassembly tool will not extend into the accommodating cavity 13, thereby preventing the possibility of damaging the battery 10, thereby improving the disassembly yield and safety during disassembly.

[0045] In another embodiment, a protruding structure 16 is provided on both the first connection surface 1226 and the second connection surface 1227, and a card slot 17 is provided on both the frame 112 and the second step surface 1212. The protruding structure 16 is connected to the card slot 17 to realize the connection between the pressing part 122, the body 121 and the frame 112, so that the body 121 is fixed to the frame 112 through the pressing part 122. With such a setting, when disassembling the battery cover 12, it is only necessary to open the pressing part 122. The disassembly process is simple, no disassembly tools are required, and there is no possibility of damaging the battery 10, thereby improving the disassembly yield and safety during disassembly, while improving the disassembly efficiency of the battery cover 12.

[0046] Combination Figure 6 and Figure 7 In one embodiment, the shell assembly further includes a height compensation structure 14, which is disposed between the frame 112 and the pressing portion 122, so that the surface of the pressing portion 122 facing away from the frame 112 is flush with the outer surface of the body 121. With such a design, on the one hand, the pressing portion 122 is indirectly connected to the frame 112 through the height compensation structure 14, so that the surface of the pressing portion 122 facing away from the frame 112 can be set as a plane, thereby making the structure of the shell assembly simple and easy to process. On the other hand, the height of the pressing portion 122 is compensated by the height compensation structure 14, so that the surface of the pressing portion 122 facing away from the frame 112 is flush with the outer surface of the body 121. In this way, while the flatness of the back of the shell assembly can be effectively improved, a gap between the pressing portion 122 and the frame 112 can be avoided, thereby effectively improving the reliability of the shell assembly.

[0047] Combination Figure 8 In one embodiment, the body 121 includes a first step surface 1211, a second step surface 1212 and a first surface 1213 connected in sequence, the first step surface 1211 is connected to the outer surface of the body 121, and the first step surface 1211 and the second step surface 1212 constitute a first avoidance structure. The pressing portion 122 includes a first side surface 1225 connected to the surface facing away from the frame 112, the first side surface 1225 is opposite to the first step surface 1211 and is in contact with the first step surface 1211, and the second connecting surface 1227 is opposite to the second step surface 1212 and is connected to the second step surface 1212.

[0048] The height compensation structure 14 includes a first abutting surface 141 and a second abutting surface 142 facing each other, and a second side surface 143 connected between the first abutting surface 141 and the second abutting surface 142, the second side surface 143 is opposite to and fits with the first surface 1213, the first abutting surface 141 is flush with the second step surface 1212, and the first abutting surface 141 is opposite to and connected to the first connecting surface 1226, and the second abutting surface 142 is opposite to and connected to the frame 112. In this way, the pressing part 122 is indirectly connected to the frame 112 through the height compensation structure 14, and at the same time, the body 121 is fixed to the frame 112, so that not only the structure of the shell assembly can be simplified, but also the reliability of the shell assembly can be effectively improved.

[0049] In one embodiment, the second connection surface 1227 is bonded to the second step surface 1212, the first connection surface 1226 is bonded to the first abutting surface 141, and the second abutting surface 142 is bonded to the frame 112. With such a configuration, the connection method is simple and the assembly efficiency of the housing assembly can be improved.

[0050] When the battery cover 12 needs to be disassembled, a disassembly tool such as a disassembly sheet can be used to extend from the connection between the pressing part 122 and the body 121 into the space between the first side surface 1225 of the pressing part 122 and the first step surface 1211 of the body 121, and then continue to extend between the second step surface 1212 of the body 121 and the second connecting surface 1227 of the pressing part 122 to destroy the adhesive layer 15 (such as double-sided tape) between the second step surface 1212 and the second connecting surface 1227. Continue to extend along the extending direction into the space between the first connecting surface 1226 of the pressing part 122 and the first abutting surface 141 of the height compensation structure 14 to destroy the adhesive layer 15 (such as double-sided tape) between the first connecting surface 1226 and the first abutting surface 141, thereby achieving the disassembly of the battery cover 12. In the above disassembly process, the disassembly tool is inserted in a direction away from the accommodating cavity 13, and thus when the battery cover 12 is disassembled, the disassembly tool will not be inserted into the accommodating cavity 13, so there is no possibility of damaging the battery 10, thereby improving the disassembly yield and safety during disassembly.

[0051] Combination Figure 8 and Fig. 9In another embodiment, the second abutting surface 142 is bonded to the frame 112, the first connecting surface 1226 and the second connecting surface 1227 are both provided with a first clamping portion, the first abutting surface 141 and the second step surface 1212 are both provided with a second clamping portion, and the first clamping portion and the second clamping portion cooperate with each other, and the cooperation mode can be, for example, a clamping cooperation mode such as a protruding structure 16 and a clamping groove 17, a buckle and a clamping groove 17, so as to achieve fixing the body 121 on the middle frame 11. With such a setting mode, when disassembling the battery cover 12, it is only necessary to open the pressing portion 122 and separate the first clamping portion from the second clamping portion. The disassembly process is simple, no disassembly tools are required, and there is no possibility of damaging the battery 10, thereby improving the disassembly yield and safety during disassembly, while improving the disassembly efficiency of the battery cover 12.

[0052] In another embodiment, the first connecting surface 1226 and the second connecting surface 1227 are both provided with a first clamping portion, the first abutting surface 141 and the second step surface 1212 are both provided with a second clamping portion, the second abutting surface 142 is provided with a third clamping portion, and the frame 112 is provided with a fourth clamping portion, and the first clamping portion and the second clamping portion cooperate with each other, and the third clamping portion and the fourth clamping portion cooperate with each other, so as to fix the body 121 on the middle frame 11. In this way, when disassembling the battery cover 12, no disassembly tool is needed.

[0053] Combination Figure 8 and Fig. 9 In one embodiment, one of the first clamping part and the second clamping part is a clamping groove 17, and the other of the first clamping part and the second clamping part is a protruding structure 16. For example, the first clamping part can be a clamping groove 17 and the second clamping part can be a protruding structure 16, or the first clamping part can be a protruding structure 16 and the second clamping part can be a clamping groove 17. With such a setting form, the structure of the housing assembly is simple and easy to process.

[0054] Combination Fig.10In one embodiment, the middle frame 11 includes two first frames 1121 and two second frames 1122 arranged opposite to each other, and the length of the first frame 1121 is greater than the length of the second frame 1122. Exemplarily, one of the two second frames 1122 constitutes the top of the electronic device 1, and the other second frame 1122 constitutes the bottom of the electronic device 1. Usually, the distance between the battery 10 and the top and bottom of the electronic device 1 is relatively far. At the same time, a camera module, a speaker module and other devices are also arranged between the battery 10 and the two second frames 1122, so that when the battery cover 12 is disassembled by using a disassembly tool, it will not be disassembled from the two second frames 1122. Therefore, in this embodiment, only the pressing parts 122 are respectively arranged on the two first frames 1121. In this way, while improving the disassembly yield and safety during disassembly, the structure of the shell assembly is simple, which is not only convenient for production and processing, but also can improve the assembly efficiency of the shell assembly.

[0055] An exemplary embodiment of the present disclosure provides an electronic device, which may be, for example, a mobile phone, a tablet computer, a laptop computer, a PDA, an in-vehicle electronic device, a wearable device, an ultra-mobile personal computer (UMPC), a netbook, or a personal digital assistant (PDA), etc., and may also be a non-mobile device such as a personal computer (PC), a television (TV), a teller machine, or a self-service machine.

[0056] like Figure 2 , Figure 3 and Figure 4 As shown, the electronic device 1 includes the housing assembly as described above. The housing assembly includes a middle frame 11 and a battery cover 12. The battery cover 12 is configured to include a body 121 and a pressing portion 122.
