[0003] The materials and processes of existing battery covers are relatively simple, making it difficult to achieve complex appearance effects, and the improvement of the look and feel of electronic devices is very limited. Utility Model Content

[0004] The embodiments of the present application provide a battery cover and an electronic device, which are used to solve the problem that the existing battery cover is difficult to achieve a complex appearance effect and has a poor effect on improving the appearance and touch of the electronic device.

[0005] In order to achieve the above purpose, the embodiment of the present application adopts the following technical solution:

[0006] In a first aspect, an embodiment of the present application provides a battery cover, which includes a cover plate, a first decorative cover and at least one second decorative cover.

[0007] The cover plate is provided with an opening, and the opening penetrates the cover plate along the thickness direction of the battery cover. The first decorative cover is arranged at the opening of the cover plate. The first decorative cover and the second decorative cover are stacked along the thickness direction of the battery cover, and the second decorative cover covers a part of the surface of the first decorative cover away from the cover plate, and the first decorative cover and the second decorative cover are assembled and fixed.

[0008] Exemplarily, the above-mentioned assembly and fixation can be a snap connection (such as transition fit, interference fit), threaded connection (for example, internal threads and external threads that match each other are respectively provided on the first decorative cover and the second decorative cover), etc., which rely on the matching relationship between the structures of the two components themselves to achieve the connection. The assembly and fixation can also be an assembly method in which the two components are connected together by additional connecting parts (such as bolts, screws, rivets, etc.).

[0009] The battery cover provided in the first aspect of the present application is decorated by assembling and fixing the first decorative cover and the second decorative cover together. In this case, the first decorative cover and the second decorative cover can be made into different shapes using different materials and different processes, and finally assembled together, so that the first decorative cover and the second decorative cover can form a more complex appearance after assembly, thereby making the battery cover have a better look and feel, and improving the user experience. In addition, the first decorative cover and the second decorative cover are assembled and fixed, which can reduce the processing difficulty and improve the processing yield rate when achieving a more complex appearance effect compared to an integrated decorative structure.

[0010] In combination with the first aspect, in a possible implementation, a plurality of second decorative covers are provided, and the plurality of second decorative covers are spaced apart on the first decorative cover. In this case, the plurality of second decorative covers can also be made into different shapes using different materials and different processes. For example, three second decorative covers can be provided, one of which is made of glass, and the other two second decorative covers are made of metal, and one surface of the two second decorative covers made of metal uses a metal brushing process, and the other surface uses a mirror process, that is, the three second decorative covers use two materials and three processes. Therefore, by providing a plurality of second decorative covers, the battery cover can have a more complex appearance effect, a better look and feel, and is conducive to improving the user experience.

[0011] In combination with the first aspect, in another possible implementation, the first decorative cover includes a plurality of sub-decorative covers, the plurality of sub-decorative covers are distributed in a direction parallel to the cover plate, and two adjacent sub-decorative covers are assembled and fixed. Thus, the plurality of sub-decorative covers can be made into different shapes using different materials and different processes, and finally assembled together, so that the first decorative cover can have a more complex appearance, thereby making the battery cover have a better look and feel, and improving the user experience.

[0012] In combination with the first aspect, in another possible implementation, a limiting groove is provided on a surface of the first decorative cover facing the second decorative cover, and the second decorative cover is at least partially inserted into the limiting groove. Alternatively, a limiting groove is provided on a surface of the second decorative cover facing the first decorative cover, and the first decorative cover is at least partially inserted into the limiting groove.

[0013] In this way, the first decorative cover and the second decorative cover cooperate with each other through the limiting groove (for example, the limiting groove is opened on the first decorative cover, and in the cross section perpendicular to the thickness direction of the battery cover, the shape of the second decorative cover is adapted to the shape of the limiting groove, and the second decorative cover is integrally inserted into the limiting groove), thereby limiting the relative movement of the first decorative cover and the second decorative cover in the direction parallel to the cover plate.

[0014] In combination with the first aspect, in another possible implementation, a limiting post is provided on the surface of the second decorative cover facing the first decorative cover, a limiting hole is provided on the surface of the first decorative cover facing the second decorative cover, and the limiting post is inserted into the limiting hole. Alternatively, a limiting hole is provided on the surface of the second decorative cover facing the first decorative cover, a limiting post is provided on the surface of the first decorative cover facing the second decorative cover, and the limiting post is inserted into the limiting hole. In this way, the cooperation between the limiting post and the limiting hole can prevent the first decorative cover and the second decorative cover from relative movement in a direction parallel to the cover plate.

[0015] In combination with the first aspect, in another possible implementation, a plurality of limiting posts are arranged at intervals, a plurality of limiting holes are arranged at intervals, and the plurality of limiting posts and the plurality of limiting holes correspond one to one. In this way, by arranging a plurality of limiting posts at intervals and a plurality of limiting holes corresponding one to one to the limiting posts, not only can the first decorative cover and the second decorative cover be prevented from relative movement in a direction parallel to the cover plate, but also relative rotation between the first decorative cover and the second decorative cover can be prevented.

[0016] In combination with the first aspect, in another possible implementation, the plurality of limiting posts include a first limiting post and a second limiting post. The limiting hole is a waist-shaped hole, and the plurality of limiting holes include a first limiting hole and a second limiting hole, and the length direction of the first limiting hole and the length direction of the second limiting hole intersect. The first limiting post is inserted into the first limiting hole, and the second limiting post is inserted into the second limiting hole. In this way, the two intersecting length directions determine a plane parallel to the cover plate, and when the waist-shaped hole cooperates with the limiting post, excessively high processing accuracy is not required. Through the cooperation between the first limiting post and the first limiting hole, and the cooperation between the second limiting post and the second limiting hole, the first decorative cover and the second decorative cover can be prevented from relative movement in a plane parallel to the cover plate, thereby achieving precise positioning between the first decorative cover and the second decorative cover.

[0017] In combination with the first aspect, in another possible implementation manner, a length direction of the first limiting hole and a length direction of the second limiting hole are perpendicular to each other.

[0018] In combination with the first aspect, in another possible implementation, in a cross section perpendicular to the thickness direction of the battery cover, the shape of the limiting column is adapted to the shape of the limiting hole, thereby preventing the first decorative cover and the second decorative cover from moving relative to each other in any direction parallel to the cover plate.

[0019] In combination with the first aspect, in another possible implementation, the battery cover further includes a fastener, and the first decorative cover is assembled and fixed with the second decorative cover by the fastener. The fastener may be a bolt, a screw, a rivet, etc. This arrangement can prevent the first decorative cover and the second decorative cover from moving relative to each other in a direction parallel to the thickness of the battery cover, and can also reduce the difficulty of assembling the first decorative cover and the second decorative cover.

[0020] In combination with the first aspect, in another possible implementation, the battery cover further includes an adhesive layer, and the first decorative cover and the second decorative cover are bonded and fixed by the adhesive layer. In this way, the adhesive layer can further improve the connection stability between the first component and the second component.

[0021] In combination with the first aspect, in another possible implementation, the battery cover further includes a third decorative cover, the third decorative cover is arranged at the opening of the cover plate, and the first decorative cover and the third decorative cover are respectively located on both sides of the cover plate, the third decorative cover is assembled and fixed to the first decorative cover, and the second decorative cover is arranged on the surface of the first decorative cover away from the third decorative cover. That is, for the electronic device, it is equivalent to the third decorative cover being located on the inner side of the cover plate, and the first decorative cover being located on the outer side of the cover plate, and the first decorative cover being fixed to the cover plate by the cooperation of the first decorative cover and the third decorative cover.

[0022] In a second aspect, the present application provides an electronic device, which includes a frame, a battery, and a battery cover provided in the first aspect, wherein the battery cover is fixed to the frame, the frame and the battery cover are surrounded to form a receiving cavity, and the battery is arranged in the receiving cavity.

[0023] It can be understood that the beneficial effects that can be achieved by the electronic device described in the second aspect and any possible implementation thereof provided above can refer to the beneficial effects in the first aspect and any possible implementation thereof, and will not be repeated here.

DETAILED DESCRIPTION

[0047] In order to make the purpose, technical solution and advantages of the application more clear, the present application is further described in detail below in conjunction with the embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0048] In the description of the present application, it should be clarified that the terms "vertical", "lateral", "longitudinal", "front", "rear", "left", "right", "up", "down", "horizontal" and the like indicating directions or positional relationships are based on the directions or positional relationships shown in the drawings, and are only for the convenience of describing the present application, and do not mean that the devices or elements referred to must have a specific direction or position, and therefore cannot be understood as limiting the present application. The "quantity" mentioned above cannot be understood as limiting the present application.

[0049] In the description of this application, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium. For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0050] The embodiment of the present application provides an electronic device. Specifically, the electronic device may be a portable electronic device or other types of electronic devices. For example, the electronic device may be a mobile phone, a tablet computer, a laptop computer, a personal digital assistant (PDA), a monitor, a camera, a personal computer, a notebook computer, a wearable device, etc. For the convenience of explanation, the following examples are all taken as an example of the electronic device being a mobile phone.

[0051] See also Figure 1 and Figure 2 As shown, Figure 1 This is a schematic diagram of the overall structure of the electronic device 01 provided in the embodiment of the present application. Figure 2 For the above Figure 1 Exploded diagram of the structure of the electronic device 01. As can be seen from the above, in this embodiment, the electronic device 01 is a mobile phone, and the electronic device 01 can be in an approximately rectangular plate-shaped structure. The electronic device 01 can include a display module 10, a housing 20, a mainboard 40, a battery 50 and a camera module 30.

[0052] Understandably, Figure 1 and Figure 2 Only some components of the electronic device 01 are schematically shown, and the actual shapes, sizes, positions and structures of these components are not subject to the present invention. Figure 1 and Figure 2 restrictions.

[0053] The above-mentioned display module 10 is used to display images, videos, etc. The display module 10 may include a transparent cover plate 11 and a display screen 12 (English name: panel 1, also called a display panel), and the transparent cover plate 11 and the display screen 12 are stacked. The material of the transparent cover plate 11 includes but is not limited to glass. For example, the transparent cover plate 11 can adopt an ordinary transparent cover plate to protect the display screen to avoid damage to the display screen due to external force, and it can play a dust-proof role. Alternatively, the transparent cover plate 11 can also adopt a transparent cover plate with a touch function, so that the electronic device 01 has a touch function, which makes it more convenient for users to use. Therefore, the present application does not specifically limit the specific material of the transparent cover plate 11.

[0054] In addition, the display screen 12 may be a flexible display screen or a rigid display screen. For example, the display screen 12 may be an organic light-emitting diode (OLED) display screen, an active-matrix organic light-emitting diode or an active-matrix organic light-emitting diode (AMOLED) display screen, a mini light-emitting diode (LED) display screen, a micro organic light-emitting diode (OLED) display screen, a micro organic light-emitting diode (OLED) display screen, a quantum dot light-emitting diode (QLED) display screen, or a liquid crystal display (LCD).

[0055] The housing 20 is used to protect the electronic components inside the electronic device 01. The housing 20 may include a battery cover 21 and a frame 22. The battery cover 21 is located on the side of the display screen 12 away from the light-transmitting cover plate 11, and is stacked with the light-transmitting cover plate 11 and the display screen 12. The frame 22 is located between the light-transmitting cover plate 11 and the battery cover 21. The battery cover 21 is fixed to the frame 22. For example, the battery cover 21 may be fixed to the frame 22 by bonding, threading, welding, snapping, etc. The light-transmitting cover plate 11 may be fixed to the frame 22 by gluing, so that the light-transmitting cover plate 11, the battery cover 21, and the frame 22 form a receiving cavity inside the electronic device 01, and the display screen 12, the main board 40, the battery 50, and the camera module 30 are all arranged in the receiving cavity.

[0056] The mainboard 40 is used to set the electronic components of the electronic device 10 and realize the electrical connection between the electronic components. The battery 50 is electrically connected to the mainboard 40 and is used to provide power to the electronic components. Exemplarily, the electronic components can be a control chip (such as a system on chip, System on Chip, SOC), a graphics control chip (Graphics Processing Unit, GPU), a universal storage (UFS), an earpiece, a flash module, a camera module 30, etc.

[0057] The camera module 30 is used to capture videos or images and can implement auto focus (AF, AutoFocus), so it can be applied to a variety of shooting scenes.

[0058] In order to allow external light to enter the camera module 30, the battery cover 21 is provided with an opening 60, and the light-entering surface of the camera module 30 is arranged opposite to the opening 60. Figure 3 As shown, Figure 3 for Figure 2 Schematic diagram of the structural explosion of the battery cover 21.

[0059] For the convenience of the following description, an XYZ coordinate system is established, where the width direction of the battery cover 21 is the X-axis direction, the length direction of the battery cover 21 is the Y-axis direction, and the thickness direction of the battery cover 21 is the Z-axis direction.

[0060] The battery cover 21 includes a cover plate 211 and a decoration module 212. The opening 60 is located on the cover plate 211 and penetrates the cover plate 211 along the thickness direction of the battery cover 21. The decoration module 212 is fixed at the opening 60, and the decoration module 212 is used to decorate the camera module 30 and the cover plate 211. Correspondingly, a light-transmitting hole 200 is opened on the decoration module 212, and external light passes through the light-transmitting hole 200 and the opening 60 in turn and then irradiates the light incident surface of the camera module 30.

[0061] Since the decorative module 212 is an integral structural part, if a more complex appearance effect is to be achieved, for example, the surface of the decorative module 212 has multiple sharp protrusions or depressions to form an effect similar to relief, this structure makes it more difficult to cut the decorative module 212 during cutting, requiring higher processing accuracy, and thus resulting in higher processing costs. In addition, since the decorative module 212 is an integral structural part, its material is single, and the improvement of the appearance and touch of the battery cover 21 is very limited.

[0062] In order to solve the above problems, the present application embodiment provides a battery cover 21, see Figure 4 and Figure 5 As shown, Figure 4 This is a schematic diagram of the overall structure of a battery cover 21 provided in an embodiment of the present application. Figure 5 for Figure 4 The battery cover 21 is an exploded view of the structure. The battery cover 21 can be applied to the electronic device 01, that is, the battery cover 21 is fixed on the frame 22.

[0063] The battery cover 21 may include a first decorative cover 213 , at least one second decorative cover 214 , and the cover plate 211 .

[0064] The cover plate 211 is provided with an opening 60, which penetrates the cover plate 211 along the thickness direction (Z-axis direction) of the battery cover 21. The first decorative cover 213 is disposed at the opening 60 of the cover plate 211. The first decorative cover 213 and the second decorative cover 214 are stacked along the thickness direction (Z-axis direction) of the battery cover 21, and the second decorative cover 214 covers a partial area of ​​the surface of the first decorative cover 213 away from the cover plate 211, and the first decorative cover 213 and the second decorative cover 214 are assembled and fixed.

[0065] It should be noted that the above-mentioned assembly and fixation can be a snap connection (such as transition fit, interference fit), threaded connection (for example, internal threads and external threads that match each other are respectively provided on the first decorative cover 213 and the second decorative cover 214), etc., which rely on the matching relationship between the structures of the two components themselves to achieve the connection. The assembly and fixation can also be an assembly method in which the two components are connected together by additional connecting parts (such as bolts, screws, rivets, etc.).

[0066] The opening 60 can be arranged near the edge of the cover plate 211, or at the geometric center of the cover plate 211, and this application does not specifically limit this. The shape of the opening 60 can be regular or irregular shapes such as circular, elliptical, rectangular, etc., which can be adapted to the outer contour of the first decorative cover 213, and will not be described in detail here.

[0067] The material of the cover plate 211 can be glass fiber, aramid fiber or other materials with high mechanical strength, heat resistance and good insulation performance. The first decorative cover 213 and the second decorative cover 214 can be made of metal materials such as stainless steel, titanium alloy, aluminum alloy, or non-metal materials such as wood, glass, plastic, etc. The materials of the first decorative cover 213 and the second decorative cover 214 can be the same or different, and this application does not specifically limit this.

[0068] In this way, the first decorative cover 213 and the second decorative cover 214 are assembled and fixed together to decorate the battery cover 21. On the one hand, the first decorative cover 213 and the second decorative cover 214 can be made into different shapes using different materials and different processes, and then assembled together, so that the first decorative cover 213 and the second decorative cover 214 can form a more complex appearance after assembly, thereby making the battery cover 21 have a better look and feel, and can improve the user experience. On the other hand, the first decorative cover 213 and the second decorative cover 214 are assembled and fixed. Compared with the integrated decorative structure, when achieving a more complex appearance effect, it can reduce the processing difficulty and improve the processing yield rate. For example, if you want to form a relief pattern with uneven shapes on the surface of the first decorative cover 213 away from the cover plate 211, you only need to assemble and fix a plurality of second decorative covers 214 of different sizes and thicknesses on the first decorative cover 213 according to a specified arrangement method, and you can combine to form a relief pattern. Compared with integrated molding by cutting, the processing difficulty is greatly reduced, which is conducive to reducing production costs.

[0069] The light-transmitting hole 200 may be provided on the first decorative cover 213, or may be provided on one of the at least one second decorative cover 214. Alternatively, the light-transmitting hole 200 may be provided on both the first decorative cover 213 and the second decorative cover 214, and in this case, the two light-transmitting holes 200 are arranged opposite to each other. For ease of understanding, the following description is based on the example that the light-transmitting holes 200 are provided on both the first decorative cover 213 and the second decorative cover 214.

[0070] In some embodiments, a plurality of second decorative covers 214 may be provided. Figure 6 As shown, Figure 6 Schematic diagram of an explosion of a first decorative cover 213 and a second decorative cover 214 in another battery cover 21 provided in an embodiment of the present application ( Figure 6 The middle cover plate 211 is omitted and not shown). Among them, the plurality of second decorative covers 214 are spaced apart on the first decorative cover 213. In this case, the plurality of second decorative covers 214 can also be made of different materials and different processes into different shapes, so that the battery cover 21 can have a more complex appearance, better look and feel, and be conducive to improving user experience.

[0071] It is understandable that the multiple second decorative covers 214 and the first decorative cover 213 can be assembled and fixed in the same manner, or the multiple second decorative covers 214 can be assembled and fixed with the first decorative cover 213 in different manners, which is not specifically limited in the present application.

[0072] For example, see Figure 6As shown, three second decorative covers 214 are provided, namely, an upper second decorative cover 214a, a middle second decorative cover 214b and a lower second decorative cover 214c. In the illustrated orientation, the upper second decorative cover 214a, the middle second decorative cover 214b and the lower second decorative cover 214c are sequentially distributed from top to bottom along the length direction (Y-axis direction) of the battery cover 21. Among them, the middle second decorative cover 214b is made of glass, and the upper second decorative cover 214a and the lower second decorative cover 214c are both made of metal. The upper second decorative cover 214a and the lower second decorative cover 214c are both assembled and fixed with the first decorative cover 213 by screws (not shown in the figure), and the surface of the upper second decorative cover 214a adopts a metal wire drawing process, and the surface of the lower second decorative cover 214c adopts a mirror finish process. The middle second decorative cover 214b made of glass is inlaid on the first decorative cover 213, and the middle second decorative cover 214b is provided with a light-transmitting hole 200. In other words, the three second decorative covers 214 are made of two materials and three processes, making the battery cover 21 look and feel very rich.

[0073] In some embodiments, the first decorative cover 213 may include a plurality of sub-decorative covers 2131, see Figure 7 As shown, Figure 7 Schematic diagram of an explosion of a first decorative cover 213 and a second decorative cover 214 in another battery cover 21 provided in an embodiment of the present application ( Figure 7 The middle cover plate 211 is omitted and not shown. The plurality of sub-decorative covers 2131 are distributed along a direction parallel to the cover plate 211 , and two adjacent sub-decorative covers 2131 are assembled and fixed.

[0074] Therefore, multiple sub-decorative covers 2131 can also be made into different shapes using different materials and different processes, and finally assembled together, so that the first decorative cover 213 can have a more complex shape, and the battery cover 21 can have a better look and feel, which can enhance the user experience.

[0075] For example, see Figure 7 As shown, the first decorative cover 213 includes three sub-decorative covers 2131, which are respectively a first sub-decorative cover 2131a, a second sub-decorative cover 2131b and a third sub-decorative cover 2131c. In the illustrated orientation, the first sub-decorative cover 2131a, the second sub-decorative cover 2131b and the third sub-decorative cover 2131c are sequentially distributed from top to bottom along the length direction (Y-axis direction) of the battery cover 21, and the two sides of the second sub-decorative cover 2131b are respectively assembled and fixed with the first sub-decorative cover 2131a and the third sub-decorative cover 2131c, and the second decorative cover 214 is provided with one, and the second decorative cover 214 is assembled and fixed with the second sub-decorative cover 2131b.

[0076] In some embodiments, see Figure 7 , and combined with Figure 8 As shown, Figure 8 for Figure 7 Schematic diagram of a cross section (parallel to the XZ plane) of the second decorative cover 214 being inserted into the limiting groove 70 on the first decorative cover 213. The first decorative cover 213 is provided with a limiting groove 70 on the surface facing the second decorative cover 214, and the second decorative cover 214 can be inserted into the limiting groove 70 as a whole.

[0077] Similarly, the limiting groove 70 may also be provided on the surface of the second decorative cover 214 facing the first decorative cover 213 , and the first decorative cover 213 may be entirely inserted into the limiting groove 70 (omitted in this schematic diagram).

[0078] In this way, the first decorative cover 213 and the second decorative cover 214 cooperate with each other through the limiting groove 70, so as to prevent the first decorative cover 213 and the second decorative cover 214 from relative movement in a direction parallel to the cover plate 211 (parallel to the XY plane), thereby achieving precise positioning between the first decorative cover 213 and the second decorative cover 214.

[0079] For example, see Figure 7 and Figure 8 As shown, the limiting groove 70 is provided on the first decorative cover 213. On the cross section perpendicular to the thickness direction of the battery cover 21 (parallel to the XY plane), the limiting groove 70 is circumferentially closed. The outer contour shape of the second decorative cover 214 is adapted to the shape of the limiting groove 70, wherein the second decorative cover 214 has two outer walls parallel to the YZ plane and two outer walls parallel to the XZ plane, and the limiting groove 70 has two inner walls parallel to the YZ plane and two inner walls parallel to the XZ plane. After the second decorative cover 214 is integrally inserted into the limiting groove 70, the two outer walls of the second decorative cover 214 parallel to the YZ plane are respectively abutted against the two inner walls of the limiting groove 70 parallel to the YZ plane, thereby preventing the first decorative cover 213 and the second decorative cover 214 from relative movement in the X-axis direction. At the same time, the two outer walls of the second decorative cover 214 parallel to the XZ plane are respectively abutted against the two inner walls of the limiting groove 70 parallel to the XZ plane ( Figure 8 (not shown) to prevent the first decorative cover 213 and the second decorative cover 214 from moving relative to each other in the Y-axis direction.

[0080] In some embodiments, see Fig. 9 , Fig.10 As shown, Fig. 9 Schematic diagram of an explosion of a first decorative cover 213 and a second decorative cover 214 in another battery cover 21 provided in an embodiment of the present application ( Fig. 9 The middle cover plate 211 is omitted and not shown. Fig.10 for Fig. 9The first decorative cover 213 has a protrusion 217 on its surface facing the second decorative cover 214 , and the protrusion 217 is inserted into the limiting groove 70 on the second decorative cover 214 .

[0081] Similarly, the protrusion 217 can also be disposed on the second decorative cover 214 , and the protrusion 217 is inserted into the limiting groove 70 on the first decorative cover 213 (omitted in this schematic diagram).

[0082] For example, see Fig. 9 and Fig.10 , and combined with Fig.11 As shown, Fig.11 for Fig. 9 Schematic diagram of a partial cross section (parallel to the XZ plane) of the first decorative cover 213 and the second decorative cover 214 after assembly. The limiting groove 70 is provided on the second decorative cover 214, and the limiting groove 70 is circumferentially closed on the cross section parallel to the cover plate 211 (parallel to the XY plane). The first decorative cover 213 has a protrusion 217, and the shape of the protrusion 217 is adapted to the shape of the limiting groove 70. After the first decorative cover 213 and the second decorative cover 214 are assembled and fixed, the protrusion 217 is inserted into the limiting groove 70. At this time, it is equivalent to the second decorative cover 214 being buckled on the first decorative cover 213. The outer wall of the protrusion 217 parallel to the YZ plane abuts against the inner wall of the limiting groove 70 parallel to the YZ plane, thereby preventing the first decorative cover 213 and the second decorative cover 214 from relative movement in the X-axis direction. At the same time, the outer wall of the protrusion 217 parallel to the XZ plane abuts against the inner wall of the limiting groove parallel to the XZ plane ( Fig.11 (not shown) to prevent the first decorative cover 213 and the second decorative cover 214 from moving relative to each other in the Y-axis direction.

[0083] For another example, see Fig.12 As shown, Fig.12 The schematic diagram of the cross section (parallel to the XZ plane) of another battery cover 21 provided in the embodiment of the present application after the first decorative cover 213 and the second decorative cover 214 are assembled. In the cross section parallel to the XY plane, the protrusion 217 on the first decorative cover 213 is annular, and correspondingly, the limiting groove 70 on the second decorative cover 214 is also annular. After the protrusion 217 is inserted into the limiting groove 70, the relative movement between the first decorative cover 213 and the second decorative cover 214 can be prevented in any direction parallel to the XY plane.

[0084] In some embodiments, see Fig.13 As shown, Fig.13 Schematic diagram of an explosion of a first decorative cover 213 and a second decorative cover 214 in another battery cover 21 provided in an embodiment of the present application ( Fig.13The middle cover plate 211 is omitted and not shown). A limiting post 218 is disposed on the surface of the second decorative cover 214 facing the first decorative cover 213 , and a limiting hole 80 is formed on the surface of the first decorative cover 213 facing the second decorative cover 214 . The limiting post 218 is inserted into the limiting hole 80 .

[0085] Similarly, the limiting column 218 can also be disposed on the surface of the first decorative cover 213 facing the second decorative cover 214 . In this case, the limiting hole 80 is disposed on the surface of the second decorative cover 214 facing the first decorative cover 213 (omitted in this schematic diagram).

[0086] On the basis of the above, a plurality of limiting columns 218 may be arranged at intervals, and correspondingly, a plurality of limiting holes 80 may also be arranged at intervals, and the plurality of limiting columns 218 and the plurality of limiting holes 80 correspond one to one.

[0087] In this way, by arranging a plurality of limit posts 218 at intervals and a plurality of limit holes 80 corresponding to the limit posts 218 one by one, in a direction parallel to the cover plate 211 (parallel to the XY plane), not only can the first decorative cover 213 and the second decorative cover 214 be prevented from making relative movement, but also because in a plane parallel to the cover plate 211 (parallel to the XY plane), the center points of the two limit holes 80 or the center points of the two limit posts 218 can determine a straight line, thereby also avoiding relative rotation between the first decorative cover 213 and the second decorative cover 214.

[0088] The above-mentioned limiting hole 80 can be a waist-shaped hole. When the waist-shaped hole cooperates with the limiting column 218, it does not require too high processing accuracy (the length of the waist-shaped hole is greater than the diameter of the limiting column 218), and it is convenient for the limiting column 218 and the limiting hole 80 to be aligned during assembly, which is conducive to improving assembly efficiency. When a waist-shaped hole is used, at least two length directions of the limiting holes 80 need to intersect, and the two intersecting length directions can determine a plane parallel to the cover plate 211, so that the first decorative cover 213 and the second decorative cover 214 can be prevented from relative movement in any direction in the plane parallel to the cover plate 211 (parallel to the XY plane).

[0089] Furthermore, in order to facilitate the processing of the two intersecting lengthwise limiting holes 80 and to facilitate the arrangement on the first decorative cover 213 or the second decorative cover 214, the lengthwise directions of the two limiting holes 80 may also be perpendicular to each other. For example, the limiting hole 80 is arranged on the first decorative cover 213, and the first decorative cover 213 is a rectangular plate-shaped structure. In order to avoid the limiting hole 80 occupying the surface near the center area of ​​the first decorative cover 213, the two intersecting lengthwise limiting holes 80 are arranged along the edge of the first decorative cover 213, and the lengthwise directions of the two limiting holes 80 are perpendicular to each other.

[0090] For example, see Fig.13As shown, two upper limit posts 218 are provided on the second decorative cover 214, and the two limit posts 218 are respectively the first limit post 218a and the second limit post 218b. Two upper limit holes 80 are provided on the first decorative cover 213, and the two limit holes 80 are respectively the first limit hole 80a and the second limit hole 80b, and the first limit hole 80a and the second limit hole 80b penetrate the first decorative cover 213 along the thickness direction of the battery cover 21 (parallel to the Z axis). The first limit hole 80a and the second limit hole 80b are both waist-shaped holes, and the length L1 direction of the first limit hole 80a (parallel to the Y axis) and the length L2 direction of the second limit hole 80b (parallel to the Y axis) intersect and are perpendicular to each other. The first limit post 218a and the second limit post 218b are both cylindrical, and the diameter of the first limit post 218a is the same as the width of the first limit hole 80a, and the diameter of the second limit post 218b is the same as the width of the second limit hole 80b.

[0091] When the first decorative cover 213 and the second decorative cover 214 are assembled and fixed, see Fig.14 and Fig.15 As shown, Fig.14 for Fig.13 A front view (along the positive direction of the Z axis) of the first decorative cover 213 and the second decorative cover 214 after being assembled, Fig.15 for Fig.14 A partial enlarged view of the position A in the middle. The first limiting column 218a is inserted into the first limiting hole 80a, and the outer wall of the first limiting column 218a abuts against the inner wall of the first limiting hole 80a parallel to its own length L1 direction, thereby preventing the first decorative cover 213 and the second decorative cover 214 from relative movement in the X-axis direction. At the same time, the second limiting column 218b is inserted into the second limiting hole 80b, and the outer wall of the second limiting column 218b abuts against the inner wall of the second limiting hole 80b parallel to its own length L2 direction, thereby preventing the first decorative cover 213 and the second decorative cover 214 from relative movement in the Y-axis direction.

[0092] In order to improve the positioning accuracy between the first decorative cover 213 and the second decorative cover 214, in the cross section parallel to the cover plate 211 (parallel to the XY plane), the shape and size of the above-mentioned limiting hole 80 can also be adapted to the shape and size of the limiting column 218 (for example, both are cylindrical, prismatic, etc.).

[0093] For example, see Fig.16 As shown, Fig.16 Schematic diagram of an explosion of a first decorative cover 213 and a second decorative cover 214 in another battery cover 21 provided in an embodiment of the present application ( Fig.16The middle cover plate 211 is omitted and not shown). Four upper limit posts 218 are provided on the second decorative cover 214, and the four limit posts 218 are respectively located near the four vertex corners of the second decorative cover 214. Correspondingly, four upper limit holes 80 are provided on the first decorative cover 213, and the limit posts 218 and the limit holes 80 are both cylindrical with equal diameters. After the limit posts 218 are inserted into the limit holes 80, they are more closely matched with the limit holes 80, so that the positioning of the second decorative cover 214 on the first decorative cover 213 is more accurate.

[0094] The above embodiment describes that the first decorative cover 213 and the second decorative cover 214 are limited by one of the limiting grooves 70 or the limiting columns 218. In addition, the above two limiting methods can be combined together to prevent relative movement between the first decorative cover 213 and the second decorative cover 214 in a direction parallel to the cover plate 211 (parallel to the XY plane).

[0095] For example, see Fig.17 As shown, Fig.17 Schematic diagram of an explosion of a first decorative cover 213 and a second decorative cover 214 in another battery cover 21 provided in an embodiment of the present application ( Fig.17 The middle cover plate 211 is omitted and not shown). The limiting groove 70 is provided on the second decorative cover 214, and the limiting groove 70 passes through the two side surfaces of the second decorative cover 214 in a direction parallel to the Y axis. The first decorative cover 213 has a protrusion 217, and the shape of the protrusion 217 is adapted to the shape of the limiting groove 70. After the first decorative cover 213 and the second decorative cover 214 are assembled and fixed, the protrusion 217 is inserted into the limiting groove 70 to prevent the first decorative cover 213 and the second decorative cover 214 from relative movement in a direction parallel to the X axis.

[0096] The bottom of the limiting groove 70 is provided with a first limiting column 218a and a second limiting column 218b extending toward the first decorative cover 213, and the first limiting column 218a and the second limiting column 218b are both cylindrical. The surface of the protrusion 217 facing the second decorative cover 214 is provided with a first limiting hole 80a and a second limiting hole 80b. The first limiting hole 80a and the second limiting hole 80b are both waist-shaped holes, and the length L1 direction of the first limiting hole 80a and the length L2 direction of the second limiting hole 80b are both parallel to the X-axis direction, so as to prevent the first decorative cover 213 and the second decorative cover 214 from relative movement in the direction parallel to the Y-axis.

[0097] By cooperating between the limiting groove 70 and the protrusion 217, and between the limiting column 218 and the limiting hole 80, the first decorative cover 213 and the second decorative cover 214 can be prevented from relative movement in any direction in a plane parallel to the cover plate 211 (parallel to the XY plane).

[0098] In some embodiments, see Fig.18 , Fig.19 As shown, Fig.18 Schematic diagram of an explosion of a first decorative cover 213 and a second decorative cover 214 in another battery cover 21 provided in an embodiment of the present application ( Fig.18 The middle cover plate 211 is omitted and not shown. Fig.19 for Fig.18 Schematic diagram of a partial cross section (parallel to the XZ plane) of the first decorative cover 213 and the second decorative cover 214 after being assembled. The battery cover 21 may also include a fastener 216. The first decorative cover 213 is assembled and fixed to the second decorative cover 214 by the fastener 216. The fastener 216 may be a bolt, a screw, a rivet, etc.

[0099] There may be one or more fasteners 216 , which may be reasonably selected according to specific needs, and this application does not impose any special limitation on this.

[0100] With this arrangement, the fastener 216 can prevent relative movement between the first decorative cover 213 and the second decorative cover 214 in a direction parallel to the thickness of the battery cover 21 (parallel to the Z axis), and can also reduce the difficulty of assembling the first decorative cover 213 and the second decorative cover 214 .

[0101] For example, see Fig.18 and Fig.19 As shown, Fig.18 The battery cover 21 is equivalent to the battery cover 21 in the above Fig.17 Two fasteners 216 are added to the battery cover 21 in the embodiment, and both fasteners 216 are screws. The first decorative cover 213 is provided with a through hole 90 that penetrates the first decorative cover 213 along the thickness direction of the battery cover 21 (parallel to the Z axis), and the second decorative cover 214 is provided with a screw hole 100 that is opposite to the through hole 90. Fig.19 As shown, one end of the screw (fastener 216) passes through the through hole 90 and is screwed into the screw hole 100, thereby preventing the first decorative cover 213 and the second decorative cover 214 from moving relative to each other in a direction parallel to the thickness of the battery cover 21. Thus, the assembly and fixation between the first decorative cover 213 and the second decorative cover 214 is completely achieved.

[0102] On the basis of the above, see Fig. 20 As shown, Fig. 20 The exploded view of another battery cover 21 provided in the embodiment of the present application is shown in FIG. Fig. 20 The battery cover 21 is equivalent to the battery cover 21 in the above Figure 5A third decorative cover 215 is added to the battery cover 21 in the embodiment. The third decorative cover 215 is arranged at the opening 60 of the cover plate 211, and the first decorative cover 213 and the third decorative cover 215 are respectively located on both sides of the cover plate 211, the third decorative cover 215 is assembled and fixed to the first decorative cover 213, and the second decorative cover 214 is arranged on the surface of the first decorative cover 213 away from the third decorative cover 215. Thus, the first decorative cover 213 can be fixed to the cover plate 211 by utilizing the assembly relationship between the first decorative cover 213 and the third decorative cover 215.

[0103] For example, see Fig.21 As shown, Fig.21 for Fig. 20 Schematic diagram of a partial cross section (parallel to the XZ plane) of the battery cover 21. The third decorative cover 215 is fixed to the first decorative cover 213 by screws, and the cover plate 211 is stuck in the gap between the first decorative cover 213 and the third decorative cover 215. That is, for the electronic device 01, it is equivalent to the third decorative cover 215 being located on the inner side of the cover plate 211, and the first decorative cover 213 being located on the outer side of the cover plate 211, and the first decorative cover 213 is fixed to the cover plate 211 by the cooperation between the first decorative cover 213 and the third decorative cover 215.

[0104] Furthermore, the battery cover 21 may further include an adhesive layer (the schematic diagram of the adhesive layer is omitted), and the adhesive layer is disposed between two adjacent components to improve the connection stability between the two adjacent components.

[0105] For example, an adhesive layer may be provided between the first decorative cover 213 and the second decorative cover 214 , an adhesive layer may be provided between the first decorative cover 213 and the third decorative cover 215 , an adhesive layer may be provided between the first decorative cover 213 and the cover plate 211 , and an adhesive layer may be provided between the third decorative cover 215 and the cover plate 211 .

[0106] Similarly, an adhesive layer may be provided between two adjacent sub-decorative covers 2131 or between two adjacent second decorative covers 214 , which will not be described in detail herein.

[0107] In the description of this specification, specific features, structures, materials or characteristics may be combined in an appropriate manner in any one or more embodiments or examples.

[0108] The above is only a specific implementation of the present application, but the protection scope of the present application is not limited thereto. Any person skilled in the art who is familiar with the present technical field can easily think of changes or substitutions within the technical scope disclosed in the present application, which should be included in the protection scope of the present application. Therefore, the protection scope of the present application should be based on the protection scope of the claims.
