Description

Technical Field

[0001] The embodiments of the present application relate to the technical field of electronic devices, and in particular to a battery cover and an electronic device. Background Art

[0002] With the development of electronic devices (such as mobile phones, tablet computers, etc.), the decorations on the battery covers of electronic devices are becoming more and more diverse. In order to improve the user experience, some electronic devices have begun to try to use embedded decorative parts to decorate the battery cover, but the provision of embedded decorative parts will reduce the strength of the existing battery cover. Utility Model Content

[0003] The embodiments of the present application provide a battery cover and an electronic device, which are used to solve the problem that the strength of the battery cover is reduced after an embedded decorative piece is provided on the existing battery cover.

[0004] In order to achieve the above purpose, the embodiment of the present application adopts the following technical solution:

[0005] In a first aspect, an embodiment of the present application provides a battery cover, which includes a decorative element and a cover plate.

[0006] The cover plate includes a first area and a second area, the cover plate has a first surface and a second surface that are opposite to each other, the first area and the second area are flush with each other on the first surface, and the thickness of the second area is greater than that of the first area, and the decorative element is embedded in the second area.

[0007] The battery cover provided in the first aspect of the present application is configured such that the cover is divided into a first area and a second area, and the thickness of the second area is greater than that of the first area, and the decorative component is embedded in the second area. This configuration is equivalent to thickening a portion of the cover, and then installing the embedded decorative component in the thickened area (i.e., the second area), thereby achieving embedded installation of the decorative component without reducing the structural strength of the cover.

[0008] In combination with the first aspect, in a possible implementation manner, the first area and the second area are distributed sequentially along a direction parallel to the battery cover.

[0009] In combination with the first aspect, in another possible implementation, the first area and the second area are provided with a plurality of them, and are alternately distributed in a direction parallel to the battery cover. In this way, it is equivalent to providing a plurality of decorative pieces. When observed from the outside, the plurality of decorative pieces are arranged at intervals on the cover plate in a direction parallel to the battery cover. The materials and shapes of the plurality of decorative pieces can be different, so that the appearance of the battery cover can be more layered, which is conducive to improving the aesthetics.

[0010] In combination with the first aspect, in another possible implementation, the first area extends around the second area. In this way, the edge of the cover plate belongs to the first area, and the thickness of the first area is uniform and flush on the second surface, so that the edge of the cover plate is easily installed against the step on the frame, thereby completing the positioning of the battery cover.

[0011] In combination with the first aspect, in another possible implementation, the cover plate further includes at least one third region, and the thickness of the third region is greater than the thickness of the first region, and the thickness of the third region is less than the thickness of the second region. In general, since the density is uniform everywhere on the cover plate, the thickness of the third region is greater than the thickness of the first region. In other words, the structural strength of the third region is greater than the structural strength of the first region, which is equivalent to the third region being able to locally reinforce the battery cover. The thickness of the third region is less than the thickness of the second region, so that when the battery cover is installed on the electronic device, the third region will not occupy too much of the internal space of the electronic device compared to the second region, thereby minimizing the impact on the normal arrangement of electronic devices in the electronic device.

[0012] In combination with the first aspect, in another possible implementation, a plurality of third regions are provided, and the thicknesses of the plurality of third regions are unequal. Thus, by providing a plurality of third regions with unequal thicknesses, each third region can be made to avoid electronic devices with different heights inside the electronic device in a targeted manner, so that the thickness of each third region can be maximized, which is beneficial to improving the overall strength of the cover.

[0013] In combination with the first aspect, in another possible implementation, the cover plate includes a bottom plate and a panel, the bottom plate has a first area and a second area, the second area is provided with a groove on the surface facing the panel, a part of the decorative piece is embedded in the groove, a through hole is provided on the panel, another part of the decorative piece extends into the through hole. In this way, the cover plate has a double-layer structure, the bottom plate as a basic part provides structural support for the entire cover plate, and the panel can be used as a decorative part (for example, the panel is made of glass, leather, wood, etc.) to decorate the bottom plate, thereby improving the appearance and touch of the cover plate.

[0014] 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 through hole is adapted to the shape of the decorative piece. In this way, when the decorative piece extends into the through hole on the panel, the side wall of the decorative piece will fit with the inner wall of the through hole, thereby preventing the decorative piece from shifting relative to the panel. In addition, the shape of the through hole is adapted to the shape of the decorative piece, so that there is almost no gap between the decorative piece and the through hole, thereby preventing foreign matter such as dust from entering, and the smooth transition also makes the battery cover have a better touch.

[0015] In combination with the first aspect, in another possible implementation, the cover plate further includes an adhesive layer, and the bottom plate and the panel are bonded and fixed by the adhesive layer. In this configuration, the bottom plate and the panel are bonded and fixed by the adhesive layer, which can simplify the assembly process between the bottom plate and the panel and facilitate the production and processing of the battery cover.

[0016] In combination with the first aspect, in another possible implementation, the panel is made of PU leather. The panel is made of PU leather, which can make the battery cover feel softer and more delicate, and have a better appearance.

[0017] In combination with the first aspect, in another possible implementation, the cover plate is made of glass fiber. Glass fiber has high mechanical strength and heat resistance, and good insulation performance, and is more suitable for the environmental conditions where the cover plate is located.

[0018] 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.

[0019] 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

[0049] 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.

[0050] 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.

[0051] 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.

[0052] 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.

[0053] 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 camera module 30, a mainboard 40, a camera decorative cover 50 and a battery 60.

[0054] 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.

[0055] The above-mentioned display module 10 is used to display images, videos, etc. The display module 10 may include a light-transmitting panel 11 and a display screen 12 (English name: panel, also called display panel), and the light-transmitting panel 11 and the display screen 12 are stacked. The material of the light-transmitting panel 11 includes but is not limited to glass. For example, the light-transmitting panel 11 can adopt an ordinary light-transmitting panel 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 light-transmitting panel 11 can also adopt a light-transmitting panel 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 light-transmitting panel 11.

[0056] 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 (MID) display screen, a micro light-emitting diode (MID) display screen, a micro organic light-emitting diode (MID) display screen, a quantum dot light-emitting diode (QLED) display screen, or a liquid crystal display (LCD).

[0057] The housing 20 is used to protect the electronic components inside the electronic device 01. The housing 20 may include a battery cover 70 and a frame 22. The battery cover 70 is located on the side of the display screen 12 away from the light-transmitting panel 11, and is stacked with the light-transmitting panel 11 and the display screen 12. The frame 22 is located between the light-transmitting panel 11 and the battery cover 70. The battery cover 70 is fixed to the frame 22. For example, the battery cover 70 may be fixed to the frame 22 by bonding, threading, welding, snapping, etc. The light-transmitting panel 11 may be fixed to the frame 22 by gluing, so that the light-transmitting panel 11, the battery cover 70, and the frame 22 form a receiving cavity inside the electronic device 01. The display screen 12, the main board 40, and the camera module 30 are all arranged in the internal receiving space.

[0058] In some embodiments, the housing 20 may further include a middle plate 23, which is disposed in the housing cavity and is located on the side of the display screen 12 away from the light-transmitting panel 11. The middle plate 23 is fixedly connected to the frame 22 to form the middle frame of the electronic device 10. For example, the middle plate 23 and the frame 22 may be fixedly connected by gluing, threading, welding, snapping, etc.; or, the middle plate 23 and the frame 22 may also be an integrally formed structure, that is, the middle plate 23 and the frame 22 form a structural component as a whole. The middle plate 23 divides the housing cavity into two independent spaces, one of which is located between the light-transmitting panel 11 and the middle plate 23, and the display screen 12 is located in the space. The other space is located between the middle plate 23 and the battery cover 70, and the main board 40, the camera module 30 and the battery 60 are all disposed in the space.

[0059] The mainboard 40 is used to set the electronic devices 80 of the electronic device 10 and realize the electrical connection between the electronic devices 80. The battery 60 is electrically connected to the mainboard 40 to provide power to the electronic devices 80. Exemplarily, the electronic device 80 can be a control chip (such as a system on chip, System on Chip, SOC), a graphics control chip (graphics process engine, GPU), a low power double data rate memory (Low Power Double Data Rate SDRAM, LPDDR), a universal flash storage (universal flash storage, UFS), an earpiece, a flash module, etc.

[0060] The camera module 30 is used to shoot videos or images and can realize auto focus (AF, AutoFocus), so it can be applied to various shooting scenes. In order to allow external light to enter the camera module 30, the battery cover 70 is provided with an opening 100, and the light-entering surface of the camera module 30 is arranged opposite to the opening 100.

[0061] The camera decorative cover 50 is disposed at the opening 100 on the battery cover 70 . The camera decorative cover 50 is used to prevent foreign objects such as dust from entering the electronic device 01 or the camera module 30 , and to prevent the camera module 30 from being scratched or hit by external objects.

[0062] Please continue to see Figure 2As shown, in order to improve the user's perception without changing the overall shape of the battery cover 70, some electronic devices 01 have begun to try to use embedded decorative parts 72 (i.e., decorative parts 72 are embedded in the battery cover 70) to decorate the battery cover 70. The shape of the decorative part 72 can be various words, symbols, patterns, etc. (for example, the decorative part 72 is the brand logo (logotype, trademark) of the manufacturer of the electronic device 01), and this application does not make special restrictions on this.

[0063] For the convenience of the following description, an XYZ coordinate system is established, with the width direction of the battery cover 70 as the X-axis direction, the length direction of the battery cover 70 as the Y-axis direction, and the thickness direction of the battery cover 70 as the Z-axis direction.

[0064] See also Figure 3 As shown, Figure 3 for Figure 2 Since the battery cover 70 is a plate-like structure with uniform thickness at all places, if the decorative member 72 is to be embedded in the battery cover 70 as a whole, a groove 200 corresponding to the size of the decorative member 72 needs to be opened on the battery cover 70, which will make the thickness of the portion of the battery cover 70 corresponding to the bottom of the groove 200 smaller (this portion can be called a "thin-walled portion"), thereby reducing the overall structural strength of the battery cover 70, and the thin-walled portion is prone to fracture when the battery cover 70 is impacted.

[0065] In order to solve the above problem, an embodiment of the present application provides a battery cover 70 , which can be applied to the above electronic device 01 , that is, the battery cover 70 is fixed on the above frame 22 .

[0066] See also Figure 4 , Figure 5 and Figure 6 As shown, Figure 4 This is a schematic diagram of the overall structure of a battery cover 70 provided in an embodiment of the present application. Figure 5 for Figure 4 Schematic diagram of the cross section at BB in the middle, Figure 6 for Figure 4 Schematic diagram of the structural explosion of the battery cover 70.

[0067] The battery cover 70 may include a cover plate 71 and the above-mentioned decorative member 72. The cover plate 71 includes a first area 710 and a second area 720 ( Figure 6 The cover plate 71 has a first surface 701 and a second surface 702 that are opposite to each other, and the first area 710 and the second area 720 are flush with each other on the first surface 701. The thickness d2 of the second area 720 is greater than the thickness d1 of the first area 710, and the decorative element 72 is embedded in the second area 720.

[0068] It should be noted that, in a cross section parallel to the battery cover 70 (parallel to the XY plane), the shapes and sizes of the first area 710 and the second area 720 may be the same or different.

[0069] The cover plate 71 is provided with an opening 100 that penetrates the cover plate 71 along the thickness direction (Z-axis direction) of the battery cover 70. The shape of the opening 100 can be regular or irregular shapes such as circular, elliptical, rectangular, etc., which can be adapted to the outer contour of the camera decorative cover 50, and will not be described in detail here.

[0070] The present application does not specifically limit the location of the opening 100. For example, the opening 100 may be located on the first area 710 or on the second area 720, or the opening 100 may span between the first area 710 and the second area 720.

[0071] In this way, by dividing the cover plate 71 into a first area 710 and a second area 720, and the thickness of the second area 720 is greater than the thickness of the first area 710, and the decorative component 72 is embedded in the second area 720 with a larger thickness, such a setting is equivalent to thickening a part of the cover plate 71, and then installing the embedded decorative component 72 in the thickened part (ie, the second area 720), so that the arrangement and installation of the decorative component 72 can be achieved without reducing the structural strength of the cover plate 71.

[0072] When the decorative member 72 is embedded in the cover plate 71, the decorative member 72 may be flush with the first surface 701 of the cover plate 71, or may be lower than or higher than the first surface 701 of the cover plate 71. For ease of understanding, the following description is based on the example that the decorative member 72 is flush with the first surface 701 of the cover plate 71.

[0073] In some embodiments, see Figure 7 As shown, Figure 7 This is a schematic diagram of the overall structure of another battery cover 70 provided in an embodiment of the present application. The first area 710 and the second area 720 may be distributed in sequence along a direction parallel to the cover plate 71 .

[0074] For example, see Figure 7 As shown, in a cross section parallel to the battery cover 70 (parallel to the XY plane), the first area 710 and the second area 720 are both rectangular, the first area 710 occupies three quarters of the cross section of the cover plate 71, the second area 720 occupies one quarter of the cross section of the cover plate 71, and the first area 710 and the second area 720 are distributed along the width direction of the cover plate 71, and the opening 100 is located in the first area 710.

[0075] For another example, see Figure 8 As shown, Figure 8This is a schematic diagram of the overall structure of another battery cover 70 provided in an embodiment of the present application. In a cross section parallel to the battery cover 70 (parallel to the XY plane), the second area 720 is triangular, the first area 710 is pentagonal, the area of ​​the first area 710 is much larger than that of the second area 720, and the second area 720 is located at the top corner of the cover plate 71, that is, the first area 710 and the second area 720 are along the diagonal line of the cover plate 71 ( Figure 8 mid-dotted line) direction distribution.

[0076] In other embodiments, see Fig. 9 , Fig.10 As shown, Fig. 9 A front view (along the negative direction of the Z axis) of a battery cover 70 provided in an embodiment of the present application is shown in FIG. Fig.10 for Fig. 9 Schematic diagram of the cross section at CC (parallel to the YZ plane). The first region 710 and the second region 720 may be provided in plurality, and the plurality of first regions 710 and the plurality of second regions 720 are alternately distributed along a direction parallel to the battery cover 70 (parallel to the XY plane).

[0077] In this way, it is equivalent to that a plurality of decorative parts 72 are also provided. When observed from the outside, the plurality of decorative parts 72 are arranged on the cover plate 71 at intervals along a direction parallel to the battery cover 70 (parallel to the XY plane). The plurality of decorative parts 72 can be made into different shapes using different materials and different processes, thereby making the appearance of the battery cover 70 more layered and helping to improve the aesthetics.

[0078] For example, please see Fig. 9 , Fig.10 As shown. There are three first areas 710 on the cover plate 71, namely, the upper first area 710a, the middle first area 710b and the lower first area 710c, and in the illustrated orientation, the upper first area 710a, the middle first area 710b and the lower first area 710c are sequentially distributed from top to bottom along the length direction of the battery cover 70 (parallel to the Y axis), and the opening 100 is located in the upper first area 710a. There are two second areas 720 on the cover plate 71, namely, the upper second area 720a and the lower second area 720c, and the upper second area 720a is located between the upper first area 710a and the middle first area 710b, and the lower second area 720c is located between the middle first area 710b and the lower first area 710c.

[0079] Correspondingly, two decorative pieces 72 are provided, namely a first decorative piece 72a and a second decorative piece 72b. Among them, the first decorative piece 72a is made of metal into the shape of the brand logo of the manufacturer of the electronic device 01, and is embedded in the upper second area 720a. The second decorative piece 72b is made of glass into other decorative shapes and is embedded in the lower second area 720c. In other words, two decorative pieces 72 are arranged on the cover plate 71 along the length direction of the battery cover 70 at intervals, and the two decorative pieces 72 are made of two materials and have two shapes, so that the appearance and touch of the battery cover 70 are very rich.

[0080] For example, see Fig.11 and Fig.12 As shown, Fig.11 A front view (along the negative direction of the Z axis) of another battery cover 70 provided in an embodiment of the present application. Fig.12 for Fig.11 Schematic diagram of the cross section (parallel to the XZ plane) at EE in the middle. Among them, there are three second areas 720, namely the left second area 720d, the middle second area 720b and the right second area 720e, and in the illustrated orientation, the left second area 720d, the middle second area 720b and the right second area 720e are distributed from left to right along the width direction of the battery cover 70 (parallel to the X axis). There are two first areas 710, namely the left first area 710d and the right first area 710e, and the left first area 710d is located between the upper left second area 720d and the middle second area 720b, and the right first area 710e is located between the middle second area 720b and the right second area 720e. The opening 100 spans between the left second area 720d and the left first area 710d.

[0081] Correspondingly, three decorative pieces 72 are provided, namely, the first decorative piece 72a, the second decorative piece 72b and the third decorative piece 72c. Among them, the first decorative piece 72a is made into other decorative shapes by metal mirror technology and is embedded in the second area 720d on the left. The second decorative piece 72b is made of glass into the shape of the brand logo of the manufacturer of the electronic device 01 and is embedded in the middle second area 720b. The third decorative piece 72c is embedded in the second area 720e on the right. The shape of the third decorative piece 72c is the same as that of the first decorative piece 72a, but it is made by metal wire drawing technology. In other words, three decorative pieces 72 are arranged at intervals on the cover plate 71 along the width direction of the battery cover 70, and the three decorative pieces 72 have two shapes, two materials, and three processes are used, so that the appearance and touch of the battery cover 70 are very rich.

[0082] In some embodiments, see Fig.13 and Fig.14 As shown, Fig.13 A front view (along the negative direction of the Z axis) of another battery cover 70 provided in an embodiment of the present application is shown in FIG. Fig.14 for Fig.13 The first region 710 can also extend around the second region 720. In this way, the edge of the cover plate 71 belongs to the first region 710, and each part of the first region 710 is flush on the second surface 702, so that it is easy to install the edge of the cover plate 71 against the step 221 on the frame 22, thereby completing the positioning of the battery cover 70.

[0083] Among them, in the cross section parallel to the cover plate 71 (parallel to the XY plane), the second area 720 can be a regular or irregular shape such as a circle, a rectangle, a trapezoid, etc. Alternatively, the shape of the second area 720 can be similar to the shape and size of the decorative element 72, so as to minimize the occupation of the second area 720 in the internal space of the electronic device 01 while meeting the requirements for embedding the decorative element 72.

[0084] For example, see Fig.13 , Fig.14 , and combined with Fig.15 As shown, Fig.15 for Fig.13 Schematic diagram of the installation of the battery cover 70. In the cross section parallel to the cover plate 71 (parallel to the XY plane), the second area 720 is circular, and in the orientation shown, the second area 720 occupies the center of the cover plate 71. The parts of the cover plate 71 except the second area 720 belong to the first area 710, and the opening 100 is located in the first area 710 and close to the upper left corner of the cover plate 71. The decorative piece 72 is also circular, and a decorative pattern is etched on the surface of the decorative piece 72 away from the cover plate 71. Fig.13 When the battery cover 70 is installed, a circle of annular steps 221 are formed on the inner wall of the frame 22. The cover 71 is inserted into the frame 22, and the edge of the cover 71 (belonging to the first area 710) is abutted against the step 221 to complete the positioning of the battery cover 70.

[0085] The cover plate 71 in the above embodiment includes a first area 710 and a second area 720. When the above cover plate 71 is installed on the frame 22 of the electronic device 01, the second area 720 is equivalent to a surface protruding from the cover plate 71 toward the inside of the electronic device 01, that is, the second area 720 will occupy a part of the space inside the electronic device 01, which may have a certain impact on the arrangement of other components in the electronic device 01, resulting in an increase in the thickness of the electronic device 01.

[0086] For example, see Fig.16 As shown, Fig.16Schematic diagram of the relative positions of a battery cover 70 and a battery 60 provided in an embodiment of the present application. The first area 710 extends around the second area 720, and the decorative element 72 ( Fig.16 After the battery cover 70 is installed, the second area 720 will contact the stress concentration area 60a ( Fig.17 The dotted-dash box) partially overlaps, so please refer to Fig.17 As shown, Fig.17 A schematic diagram of a second area 720 of a battery cover 70 provided in an embodiment of the present application covering a stress concentration area 60a of a battery 60. To protect the stress concentration area 60a of the battery 60, the second area 720 is enlarged to cover the entire stress concentration area 60a.

[0087] At this time, see Fig.18 As shown, Fig.18 for Fig.17 Schematic diagram of the relative positions of the battery cover 70 and the battery 60. Since an NFC (Near Field Communication) coil 90 is also required to be provided on the surface of the battery 60 close to the battery cover 70, in order to accommodate the NFC coil 90, a larger gap must be provided between the second area 720 of the battery cover 70 and the battery 60 (the height of the gap must be greater than the thickness of the NFC coil 90), which will increase the thickness of the electronic device 01.

[0088] Therefore, in order not to increase the thickness of the electronic device 01, see Fig.19 and Fig. 20 As shown, Fig.19 A schematic diagram of the relative positions of a battery cover 70 and an NFC coil 90 provided in an embodiment of the present application, Fig. 20 for Fig.19 Schematic diagram of the overall structure of the battery cover 70 in FIG. 7 (back view). According to the size of the NFC coil 90, the portion of the second area 720 opposite to the NFC coil 90 can be thinned to avoid the NFC coil 90, that is, a certain space is freed up on the second area 720 to accommodate the NFC coil 90, and the thinned portion of the second portion 722 can be used as the third area 730, and the thickness d3 of the third area 730 is greater than the thickness d1 of the first area 710 and less than the thickness d2 of the second area 720. In this way, the third area 730 will not only not affect the arrangement of the NFC coil 90, but also because the density of each part on the cover plate 71 is uniform, the thickness d3 of the third area 730 is greater than the thickness d1 of the first area 710. In other words, the strength of the third area 730 is greater than the strength of the first area 710, which is equivalent to the third area 730 being able to locally reinforce the cover plate 71.

[0089] In the above embodiments, the third region 730 is equivalent to being connected to the second region 720. In other embodiments, the third region 730 and the second region 720 may also be separated by the first region 710, and the thickness d3 of the third region 730 is greater than the thickness d1 of the first region 710 and less than the thickness d2 of the second region 720. In this case, the third region 730 can still play a certain reinforcing role on the cover plate 71.

[0090] For example, see Fig.21 As shown, Fig.21 A schematic diagram of the overall structure of another battery cover 70 provided in an embodiment of the present application (back view). Among them, the second area 720 is located at the center of the cover plate 71, and the first area 710 extends around the second area 720. The third area 730 is annular, and the third area 730 is located at the edge of the cover plate 71 and extends around the first area 710. In this way, the third area 730 can play a certain reinforcement role on the edge position of the cover plate 71, thereby reducing the risk of breakage and damage when the edge of the cover plate 71 is impacted (for example, the electronic device 01 falls from a height and hits the ground).

[0091] In some embodiments, see Fig. 22 As shown, Fig. 22 A front view (along the negative direction of the Z axis) of another battery cover 70 provided in an embodiment of the present application. A plurality of third regions 730 may be provided, and the thicknesses of the plurality of third regions 730 are unequal. In this way, by providing a plurality of third regions 730 of unequal thicknesses, the electronic devices 80 with different heights in the thickness direction of the electronic device 01 inside the electronic device 01 can be avoided in a targeted manner, so that the thickness of each third region 730 can be maximized, which is beneficial to improving the overall strength of the cover plate 71.

[0092] For example, see Fig. 22 , and combined with Fig.23 As shown, Fig.23 for Fig. 22 The cover plate 71 is provided with two third regions 730, namely a left third region 730a and a right third region 730b.

[0093] Two electronic components 80 are disposed on the main board 40 , namely a first electronic component 80 a and a second electronic component 80 b .

[0094] After the battery cover 70 is installed, the main board 40 and the battery cover 70 are parallel to each other, the left third area 730a is opposite to the first electronic device 80a, and the right third area 730b is opposite to the second electronic device 80b.

[0095] Since the distance between the main board 40 and the battery cover 70 remains unchanged, and in the thickness direction of the electronic device 01, the height of the first electronic device 80a is smaller than the height of the second electronic device 80b, in order to maximize the strength of the cover 71 through the left third area 730a and the right third area 730b without affecting the normal arrangement of the first electronic device 80a and the second electronic device 80b, the thickness of the left third area 730a needs to be greater than the thickness of the right third area 730b.

[0096] Furthermore, in order to prevent the impact force from being directly transmitted to the electronic device 80 through the battery cover 70 and damaging the electronic device 80 when the battery cover 70 is impacted, a certain gap exists between the third area 730a on the left and the first electronic device 80a, and between the third area 730b on the right and the second electronic device 80b, so as to utilize the gap to block the conduction path of the impact force.

[0097] On the basis of the above, in order to further improve the texture of the cover plate 71, the cover plate 71 can adopt a double-layer structure. Please refer to FIG. 24, Fig.24 A schematic diagram of an exploded structure of a battery cover 70 provided in an embodiment of the present application.

[0098] The cover plate 71 may include a stacked bottom plate 711 and a panel 712. The bottom plate 711 may be made of a relatively strong material, thereby providing structural support to the entire cover plate 71 as a base part. For example, the bottom plate 711 may be made of glass fiber, metal, aramid fiber, etc., which is not specifically limited in the present application.

[0099] The bottom plate 711 has a first area 710 , a second area 720 and a third area 730 , and the first area 710 , the second area 720 and the third area 730 are flush on the surface of the bottom plate 711 facing the panel 712 .

[0100] The panel 712 is a plate-like structure with uniform thickness at all locations, and the panel 712 can use materials with better appearance and touch to decorate the bottom plate 711. For example, the material of the panel 712 can be PU (Poly Urethane) leather, PE (Polyethy lene) leather, glass, etc., and this application does not make any special restrictions on this.

[0101] In the above case, the surface of the panel 712 away from the bottom plate 711 is the aforementioned first surface 701, and the surface of the bottom plate 711 away from the panel 712 is the aforementioned second surface 702. The opening 100 penetrates the bottom plate 711 and the panel 712 along the thickness direction (Z-axis direction) of the battery cover 70.

[0102] To securely embed the decorative element 72 on the cover plate 71, please continue to refer to Fig.24 A groove 200 is provided on the surface of the second area 720 of the bottom plate 711 facing the panel 712, and a portion of the decorative member 72 can be embedded in the groove 200. In order to ensure that the decorative member 72 can still be observed from the outside after being embedded in the cover plate 71, a through hole 300 needs to be provided on the panel 712, and another portion of the decorative member 72 extends into the through hole 300.

[0103] Furthermore, in a cross section perpendicular to the thickness direction of the battery cover 70, the shape of the through hole 300 is adapted to the shape of the decorative member 72. Thus, when the decorative member 72 extends into the through hole 300 on the panel 712, the side wall of the decorative member 72 will fit with the inner wall of the through hole 300, thereby preventing the decorative member 72 from shifting relative to the panel 712.

[0104] Furthermore, the shape of the through hole 300 is adapted to the shape of the decorative member 72 , so that there is almost no gap between the decorative member 72 and the through hole 300 , thereby preventing dust and other foreign matter from entering, and the smooth transition also makes the battery cover 70 have a better touch.

[0105] For example, please see Fig.24 , and combined with Fig.25 , Fig.26 As shown, Fig.25 for Fig.24 A partial enlarged view of the G in the middle. Fig.26 for Fig.24 Schematic diagram of a cross section of the battery cover 70. The second area 720 and the third area 730 are distributed along the width direction (X-axis direction) of the bottom plate 711 and are connected. The first area 710 extends around the portion formed by the second area 720 and the third area 730. In a cross section parallel to the cover plate 71 (parallel to the XY plane), the second area 720 and the third area 730 are both rectangular.

[0106] The decorative member 72 includes a first portion 721 and a second portion 722 distributed along the thickness direction of the battery cover 70. The first portion 721 is in the shape of a rectangular plate (i.e., equivalent to the base of the decorative member 72), and accordingly, a rectangular groove 200 adapted to the size of the first portion 721 of the decorative member 72 is provided on the second region 720, the first portion 721 is embedded in the groove 200, and the surface of the first portion 721 away from the second surface 702 is flush with the surface of the bottom plate 711 facing the panel 712.

[0107] The second part 722 is a plurality of embossed letters representing the brand name of the manufacturer of the electronic device 01 . Accordingly, the panel 712 is provided with a plurality of through holes 300 that completely correspond in size and shape to the letters.

[0108] See also Fig. 27 As shown, Fig. 27for Fig.26 A partial enlarged view of the K in the middle. When the panel 712 is fitted with the bottom plate 711, the embossed letters (the second part 722) will be inserted into the corresponding through holes 300, and the outer wall of each letter will fit tightly with the inner wall of the corresponding through hole 300, and the surface of the embossed letters (the second part 722) away from the bottom plate 711 will be flush with the first surface 701. With this arrangement, even when observed from a relatively side position, each letter can be clearly distinguished, making the electronic device 01 more recognizable.

[0109] On the basis of the above, the cover plate 71 may further include an adhesive layer (omitted in this schematic diagram). The bottom plate 711 and the panel 712 are bonded and fixed by the adhesive layer. In this way, the bottom plate 711 and the panel 712 are bonded and fixed by the adhesive layer, which can simplify the assembly process between the bottom plate 711 and the panel 712 and facilitate the production and processing of the battery cover 70.

[0110] It is understandable that the adhesive layer can be epoxy resin adhesive, polyurethane hot melt adhesive, acrylic resin adhesive, reactive hot melt adhesive, photosensitive adhesive, organic silicone adhesive, foam double-sided adhesive, etc., and this application does not specifically limit this. In the description of this specification, specific features, structures, materials or characteristics can be combined in any one or more embodiments or examples in a suitable manner.

[0111] 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.
