As their application scenarios continue to expand, people have higher requirements for the appearance of mobile phones and other electronic products.

[0003] The battery cover is a crucial exterior component in electronic products like mobile phones, and its refinement significantly impacts the overall appearance of the device. For example, in mobile phones, to meet assembly and structural strength requirements, a gap must be left between the battery cover and the phone's midframe, impacting both the phone's aesthetics and user experience. Summary of the Invention

[0004] The present disclosure provides an electronic device to solve at least some of the problems in the prior art.

[0005] In order to achieve the above objectives, the technical solutions adopted in this disclosure are:

[0006] An embodiment of the present disclosure provides an electronic device, comprising: a middle frame and a battery cover, wherein the middle frame comprises a first assembly surface and a second assembly surface, wherein the second assembly surface and the first assembly surface enclose a receiving portion, and a side end of the battery cover is assembled in the receiving portion;

[0007] The battery cover includes a side surface, a first surface fixed to the first assembly surface, and a second surface facing away from the first surface, the side surface being connected between the first surface and the second surface; the side surface is inclined relative to the second surface, and the angle between the side surface and the second surface is less than 90°; the side surface is inclined relative to the second assembly surface, and the gap between an end of the side surface close to the second surface and the second assembly surface is smaller than the gap between an end of the side surface close to the first surface and the second assembly surface.

[0008] Optionally, the angle between the side surface and the second surface ranges from 75° to 85°; and / or

[0009] An included angle between the side surface and the second assembly surface ranges from 5° to 15°.

[0010] Optionally, the first surface is a curved surface, the side surface is arranged parallel to the first surface, and the first assembly surface is arranged parallel to the first surface.

[0011] Optionally, a decorative piece is further included, wherein an opening is formed in the middle of the battery cover, and the decorative piece is assembled into the opening from the first surface;

[0012] A notch is formed on the end of the inner wall of the opening close to the second surface, so that a convex portion is formed on the end of the inner wall of the opening close to the first surface, and the convex portion abuts against the side wall of the decorative component.

[0013] Optionally, the side wall of the decorative part close to the first surface protrudes outward to form a protrusion; a recessed portion is formed on the first surface close to the opening, and the portion of the first surface located between the recessed portion and the protrusion abuts against the protrusion together with the protrusion.

[0014] Optionally, two adjacent sides of the opening are provided with the protrusions, and each side is provided with at least one protrusion.

[0015] Optionally, the raised portion includes at least one of the following structures: a step structure, a boss structure, and an arc structure.

By tilting the side surface relative to the second surface and forming an acute angle with each other, after the battery cover and the middle frame are assembled, a smaller gap can be formed between the end of the battery cover close to the second surface and the middle frame, and a larger gap can be formed between the end of the battery cover close to the first surface and the middle frame. The larger gap can reduce the possibility of the battery cover being squeezed and broken by the middle frame during the drop of the entire device, and the smaller gap can improve the aesthetics between the appearance surface of the battery cover and the middle frame and the user experience.

[0025] The present disclosure will be described in detail below with reference to the specific embodiments shown in the accompanying drawings. However, these embodiments do not limit the present disclosure, and any structural, methodological, or functional changes made by those skilled in the art based on these embodiments are included within the scope of protection of the present disclosure.

[0026] The terms used in this disclosure are for the purpose of describing specific embodiments only and are not intended to limit the disclosure. As used in this disclosure and the appended claims, the singular forms "a," "an," "the," and "the" are intended to include the plural forms as well, unless the context clearly indicates otherwise. It should also be understood that the term "and / or" as used herein refers to and encompasses any and all possible combinations of one or more of the associated listed items.

[0027] The present disclosure provides an electronic device. The electronic device of the present disclosure is described in detail below with reference to the accompanying drawings. In the absence of conflict, the features of the following embodiments and implementations can be combined with each other.

[0028] See also Figure 1 and Figure 2 As shown, an embodiment of the present disclosure provides a battery cover 10 for an electronic device, wherein the battery cover 10 includes a side surface 11, a first surface 12 for fixing to a middle frame 90 of the electronic device, and a second surface 13 facing away from the first surface 12, and the side surface 11 is connected between the first surface 12 and the second surface 13. The side surface 11 is tilted relative to the second surface 13, and the angle α between the side surface 11 and the second surface 13 is less than 90°. The angle α can range from 75° to 85° and can be set according to actual needs, and the present disclosure does not impose any restrictions on this. The first surface 12 can be provided with a backing glue 14 for fixing to the middle frame 90.

[0029] like Figure 2As shown, the larger the angle β between the mating surfaces of the middle frame 90 and the battery cover 10 at adjacent positions after assembly, the stronger the structural strength of the entire device, and the less likely the middle frame 90 is to deform during a drop of the entire device. However, the side surface of a typical battery cover is perpendicular to the exterior surface, which results in a very small gap between the battery cover and the middle frame after assembly. During a drop of the entire device, the battery cover is easily squeezed by the middle frame and broken. In the example shown in the figure, the middle frame 90 includes a first assembly surface 91 and a second assembly surface 92. The second assembly surface 92 can be understood as a mating surface. The first surface 12 is used to fix with the first assembly surface 91. The side surface 11 is tilted relative to the second assembly surface 92. An angle γ is formed between the second assembly surface 92 of the middle frame 90 and the side surface 11 of the battery cover. The angle γ can range from 5° to 15°, depending on the inclination angle of the side surface 11 relative to the second surface 13. This is not limited in the present disclosure. A gap between an end of the side surface 11 close to the second surface 13 and the second assembly surface 92 is smaller than a gap between an end of the side surface 11 close to the first surface 12 and the second assembly surface 92 .

[0030] The battery cover 10 of the disclosed embodiment is assembled with the middle frame 90 via its first surface 12. The second surface 13 serves as the exterior surface of the battery cover 10. By tilting the side surface 11 relative to the second surface 13 and forming an acute angle α therebetween, the side surface 11 and the second surface 13 are non-perpendicular. After the battery cover 10 is assembled with the middle frame 90, a smaller gap is formed between the end of the battery cover 10 closest to the second surface 13 and the middle frame 90, while a larger gap is formed between the end of the battery cover 10 closest to the first surface 12 and the middle frame 90. This creates a larger angle γ between the second assembly surface 92 of the middle frame 90 and the side surface 11 of the battery cover 10. This smaller gap enhances the aesthetics and user experience of the battery cover 10's exterior and the middle frame 90. The larger gap provides a certain amount of space between the battery cover 10 and the middle frame 90, reducing the risk of the battery cover 10 being crushed by the middle frame 90 during a drop. While ensuring the strength of the middle frame, the damage to the battery cover is reduced, achieving the goal of compatibility between the aesthetics and strength of the entire device.

[0031] In some optional embodiments, the first surface 12 is curved, and the side surface 11 is arranged parallel to the first surface 12, thereby forming a battery cover with a curved surface structure, which meets the assembly requirements of different models. The side surface 11 is inclined relative to the second surface 13, forming an acute angle between them, which can also meet the curvature requirements of the battery cover.

[0032] The battery cover can be a plastic battery cover, a ceramic battery cover, a glass battery cover, etc. Take a curved glass battery cover as an example. Before the hot bending process of the glass battery cover, an engraving machine can be used to cut off a corner of the body portion of the battery cover 10 (that is, the side surface 11), so that an acute angle α is formed between the side surface 11 of the battery cover and the appearance surface (that is, the second surface 13). After the hot bending process, a battery cover structure in which the body portion is not perpendicular to the curved surface of the battery cover is obtained. By adopting the battery cover disclosed in the present invention, it is possible to set a larger angle for the mating surface angle β of the middle frame 90 used for assembly with the battery cover 10, thereby improving the strength of the middle frame 90. The example described in the figure takes the angle β as greater than 120°.

[0033] At the same time, the battery cover of the present disclosure can also form a relatively large angle γ between the mating surface of the middle frame 90 for assembly with the battery cover 10 and the resting position of the battery cover 10, while satisfying the curved surface structure. The angle γ between the side surface 11 and the second assembly surface 92 can range from 5° to 15°, depending on the inclination angle of the side surface 11 relative to the second surface 13, and is not limited by the present disclosure. Due to the existence of this angle γ, even if there is a slight deformation due to stress inside the middle frame, the middle frame will not squeeze the battery cover. Therefore, when the middle frame is subjected to external force, such as when it falls from a height, the battery cover is not easily crushed by the middle frame.

[0034] Furthermore, with the battery cover disclosed herein, a smaller gap is formed between the end of the battery cover 10 close to the second surface 13 and the middle frame 90. This smaller gap is located on the exterior surface of the battery cover. This can minimize the visual gap of the battery cover while maintaining the accuracy achievable by existing processing technology, thereby improving the refinement of the entire device.

[0035] join Figure 1 and Figure 3 As shown, in some optional embodiments, an opening 15 for mounting a decorative member 80 is provided in the middle of the battery cover 10. A notch 19 is formed on the inner wall of the opening 15 near the end of the second surface 13, so that a raised portion 16 is formed on the inner wall of the opening 15 near the end of the first surface 12. The raised portion 16 is configured to abut against the decorative member 80. Optionally, the raised portion 16 may be an inverted step-shaped structure. The notch 19 is provided along the inner wall of the opening 15, thereby forming a raised portion 16 around the inner wall of the opening 15.

[0036] Taking the camera as an example, decorative component 80 is typically designed with a full-circle gap between the camera and the battery cover opening. This gap inevitably introduces floating tolerances during camera assembly, increasing the camera's misalignment tolerance relative to the battery cover. Since the battery cover is aligned with the midframe using the center of the battery cover as a reference, this misalignment can cause the camera's center to misalign with the center of the opening, impacting the overall aesthetics of the device.

[0037] The battery cover disclosed herein has a raised portion 16 formed on the end of the inner wall of the opening 15 near the first surface 12. The raised portion 16 abuts against the decorative piece 80, and the decorative piece can be positioned by relying on the raised portion 16 to achieve zero gap between the battery cover 10 and the decorative piece 80, thereby eliminating the floating tolerance between the decorative piece and the battery cover, improving the assembly accuracy of the decorative piece, and enhancing the appearance of the entire device.

[0038] Furthermore, a recessed portion 17 is formed on the first surface 12 near the opening 15, thereby forming a reverse-stepped battery cover with a crater. The portion of the first surface 12 between the recessed portion 17 and the raised portion 16 cooperates with the raised portion 16 to abut against the decorative element 80. Figure 3 As shown, with the above arrangement, the side of the raised portion 16 abuts the decorative member 80 horizontally, while the raised portion 16 and the portion of the first surface 12 between the recessed portion 17 and the raised portion 16 abut against the decorative member 80 vertically. This effectively positions the decorative member 80 from two directions, achieving a zero gap between the battery cover 10 and the decorative member 80. This eliminates floating tolerances between the decorative member and the battery cover, improves the assembly accuracy of the decorative member, and enhances the overall appearance of the device. In this embodiment, the sidewall of the decorative member 80 protrudes outwardly on the side closest to the first surface 12 to form a raised portion 81. The portion of the first surface 12 between the recessed portion 17 and the raised portion 16 abuts the raised portion 81 together with the raised portion 16. Optionally, the notch 19 may be filled with a sealant 18. The sealant 18 can be formed by filling the notch 19 with PUR glue. The sealant 18 not only secures the decorative member 80 but also provides a better seal and waterproofing.

[0039] The present disclosure also provides an electronic device, which may be a mobile phone, a tablet computer, or the like. The electronic device may include: a middle frame 90 and a battery cover 10, wherein the middle frame 90 includes a first assembly surface 91 and a second assembly surface 92, wherein the second assembly surface 92 and the first assembly surface 91 enclose a receiving portion, and the side end of the battery cover 10 is assembled in the receiving portion. The battery cover 10 includes a side surface 11, a first surface 12 for fixing to the first assembly surface 91, and a second surface 13 facing away from the first surface 12, wherein the side surface 11 is connected between the first surface 12 and the second surface 13. The side surface 11 is tilted relative to the second surface 13, and the angle between the side surface 11 and the second surface 13 is less than 90°. The side surface 11 is tilted relative to the second assembly surface 92, and the gap between the end of the side surface 11 close to the second surface 13 and the second assembly surface 92 is smaller than the gap between the end of the side surface 11 close to the first surface 12 and the second assembly surface 92. The angle α can be between 75° and 85° and can be set according to actual needs. This disclosure does not impose any restrictions on this. The first surface 12 can be provided with adhesive 14 for fixing to the middle frame 90. It can be understood that the inner wall of the middle frame 90 is formed with the receiving portion around the perimeter, and the outer perimeter of the battery cover 10 is assembled within the receiving portion.

[0040] like Figure 2 As shown, the larger the angle β between the mating surfaces of the middle frame 90 and the battery cover 10 at adjacent positions after assembly, the stronger the structural strength of the entire device, and the less likely the middle frame 90 is to deform during a drop of the entire device. However, the side surface of the battery cover is typically perpendicular to the exterior surface, which results in a very small gap between the battery cover and the middle frame after assembly. This makes it easy for the battery cover to be squeezed by the middle frame and break when the entire device falls. In the example shown in the figure, the middle frame 90 includes a first assembly surface 91 and a second assembly surface 92, where the second assembly surface 92 can be understood as a mating surface. The first surface 12 is used to secure to the first assembly surface 91, and the side surface 11 is tilted relative to the second assembly surface 92. An angle γ is formed between the second assembly surface 92 of the middle frame 90 and the side surface 11 of the battery cover. The gap between the end of the side surface 11 near the second surface 13 and the second assembly surface 92 is smaller than the gap between the end of the side surface 11 near the first surface 12 and the second assembly surface 92.

[0041] In the electronic device of the disclosed embodiment, the battery cover 10 is assembled with the middle frame 90 via its first surface 12. The second surface 13 serves as the exterior surface of the battery cover 10. By tilting the side surface 11 relative to the second surface 13 and forming an acute angle α therebetween, i.e., by disposing the side surface 11 and the second surface 13 at a non-perpendicular relationship, the battery cover 10 and the middle frame 90 can be assembled to form a smaller gap between the end of the battery cover 10 closest to the second surface 13 and the second assembly surface 92 of the middle frame 90, while a larger gap is formed between the end of the battery cover 10 closest to the first surface 12 and the second assembly surface 92 of the middle frame 90. This creates a larger angle γ between the second assembly surface 92 of the middle frame 90 and the side surface 11 of the battery cover 10. This smaller gap enhances the aesthetics and user experience of the battery cover 10 and the middle frame 90, while the larger gap provides a certain amount of space between the battery cover 10 and the middle frame 90, thereby reducing the risk of the battery cover 10 being crushed by the middle frame 90 during a drop. While ensuring the strength of the middle frame, the damage to the battery cover is reduced, achieving the goal of compatibility between the aesthetics and strength of the entire device.

[0042] In some optional embodiments, the first surface 12 is curved, and the side surface 11 is arranged parallel to the first surface 12, thereby forming a curved battery cover structure to meet the assembly requirements of different models. The side surface 11 is tilted relative to the second surface 13, forming an acute angle between them, which can also meet the curvature requirements of the battery cover. The first assembly surface 91 is arranged parallel to the first surface 12, and the curvature of the two is consistent, which facilitates the fixation of the battery cover 10 to the middle frame 90.

[0043] The battery cover can be a plastic battery cover, a ceramic battery cover, a glass battery cover, etc. Take a curved glass battery cover as an example. Before the hot bending process of the glass battery cover, an engraving machine can be used to cut off a corner of the body portion of the battery cover 10 (that is, the side surface 11), so that an acute angle α is formed between the side surface 11 of the battery cover and the appearance surface (that is, the second surface 13). After the hot bending process, a battery cover structure in which the body portion is not perpendicular to the curved surface of the battery cover is obtained. By adopting the battery cover disclosed in the present invention, it is possible to set a larger angle for the mating surface angle β of the middle frame 90 used for assembly with the battery cover 10, thereby improving the strength of the middle frame 90. The example described in the figure takes the angle β as greater than 120°.

[0044] Furthermore, with the electronic device disclosed herein, the battery cover can also form a relatively large angle γ between the mating surface of the middle frame 90 for assembly with the battery cover 10 and the support portion of the battery cover 10, while still maintaining a curved surface structure. This angle γ prevents the middle frame from squeezing the battery cover even if the middle frame experiences slight internal deformation. Consequently, the battery cover is less likely to be crushed by the middle frame when subjected to external forces, such as when dropped from a height.

[0045] Furthermore, in the electronic device disclosed herein, a small gap is formed between the end of the battery cover 10 close to the second surface 13 and the middle frame 90. This small gap is located on the exterior surface of the battery cover. Under the premise that the accuracy achievable by the existing processing technology remains unchanged, the visual gap of the battery cover can be minimized, thereby improving the refinement of the entire device.

[0046] In some optional embodiments, the electronic device may further include a decorative piece 80. An opening 15 is provided in the middle of the battery cover 10, and the decorative piece 80 is assembled into the opening 15 from the first surface 12. A notch 19 is formed on the inner wall of the opening 15 near the end of the second surface 13, so that a protrusion 16 is formed on the inner wall of the opening 15 near the end of the first surface 12, and the protrusion 16 abuts against the side wall of the decorative piece 80. Optionally, the decorative piece 80 may be a post-installed device such as a camera. The protrusion 16 may be an inverted step-type structure. The notch 19 is provided along the inner wall of the opening 15, thereby forming a protrusion 16 around the inner wall of the opening 15.

[0047] Taking the camera as an example, decorative component 80 is typically designed with a full-circle gap between the camera and the battery cover opening. This gap inevitably introduces floating tolerances during camera assembly, increasing the camera's misalignment tolerance relative to the battery cover. Since the battery cover is aligned with the midframe using the center of the battery cover as a reference, this misalignment can cause the camera's center to misalign with the center of the opening, impacting the overall aesthetics of the device.

[0048] In the electronic device disclosed herein, a protrusion 16 is formed on the inner wall of the opening 15 of the battery cover at the end near the first surface 12. The protrusion 16 abuts against the decorative part 80, and the decorative part can be positioned by relying on the protrusion 16 to achieve zero gap between the battery cover 10 and the decorative part 80, thereby eliminating the floating tolerance between the decorative part and the battery cover, improving the assembly accuracy of the decorative part, and enhancing the appearance of the entire device.

[0049] Furthermore, a recessed portion 17 is formed on the first surface 12 near the opening 15, thereby forming a reverse-stepped battery cover with a crater. The portion of the first surface 12 between the recessed portion 17 and the raised portion 16 cooperates with the raised portion 16 to abut against the decorative element 80. Figure 3 As shown, through the above arrangement, the side surface of the raised portion 16 abuts the decorative member 80 horizontally, and the raised portion 16 cooperates with the portion of the first surface 12 located between the recessed portion 17 and the raised portion 16 to abut the decorative member 80 vertically, thereby effectively positioning the decorative member 80 from two directions. This creates a zero gap between the battery cover 10 and the decorative member 80, thereby eliminating floating tolerances between the decorative member and the battery cover, improving the assembly accuracy of the decorative member, and enhancing the overall appearance of the device. In this embodiment, the side wall of the decorative member 80 protrudes outwardly to form a raised portion 81 on the side near the first surface 12. The portion of the first surface 12 located between the recessed portion 17 and the raised portion 16 abuts the raised portion 81 together with the raised portion 16. The raised portion 81 can be formed along the perimeter of the side wall of the decorative member 80, and the notch 19 is provided along the inner wall of the opening 15, thereby forming the raised portion 16 along the inner wall of the opening 15, thereby correspondingly cooperating with the raised portion 81. Optionally, the notch 19 may be filled with a sealant 18 , which may be formed by filling the notch 19 with PUR glue. The sealant 18 may not only fix the decorative component 80 , but also achieve better sealing and waterproofing effects.

[0050] Optionally, the raised portion 16 is provided on two adjacent sides of the opening 15, with at least one raised portion 16 provided on each side. The number and position of the raised portions 16 can be adjusted based on the actual installation requirements of the decorative member 80. The raised portion 16 can include at least one of the following structures: a stepped structure, a boss structure, or an arcuate structure. The shape of the raised portion 16 can also be adjusted based on the actual installation requirements of the decorative member 80, and this disclosure does not limit this. In this embodiment, the raised portion 16 is a stepped structure as an example.

[0051] The notch portion 19 includes at least: a first portion 191 located on a side close to the second surface 13 and a second portion 192 located on a side close to the raised portion 16. The second portion 192 is connected to the first portion 191 to form the notch portion 19. The size of the first portion 191 is larger than that of the second portion 192. In this manner, filling the notch portion 19 with the sealant 18 can increase the volume of the sealant 18 between the opening portion of the battery cover 10 in the notch portion 19 and the decorative member 80, so as to improve the connection strength between the battery cover 10 and the decorative member 80.

[0052] Other embodiments of the present disclosure will readily occur to those skilled in the art after considering the specification and practicing the disclosure herein. This disclosure is intended to cover any variations, uses, or adaptations of the present disclosure that follow the general principles of the present disclosure and include common knowledge or customary techniques in the art not disclosed herein. The description and examples are to be considered as exemplary only, with the true scope and spirit of the present disclosure being indicated by the claims.

[0053] It should be understood that the present disclosure is not limited to the exact structures that have been described above and shown in the drawings, and that various modifications and changes can be made without departing from the scope thereof. The scope of the present disclosure is limited only by the appended claims.
