Description

Technical Field

[0001] The present application belongs to the technical field of electronic equipment, and specifically relates to an electronic equipment. Background Art

[0002] To further reduce the thickness of electronic devices, battery covers have become increasingly thinner. However, thinner battery covers reduce their strength, which in turn reduces their ability to protect the battery. To improve battery safety, the battery cover's puncture resistance needs to be enhanced, so an ultra-high molecular weight polyethylene (UHMWPE) protective plate is embedded within the battery cover. However, embedding the protective plate within the battery cover complicates the manufacturing process and increases manufacturing costs. Utility Model Content

[0003] The present application aims to provide an electronic device that at least solves one of the battery safety issues of an ultra-thin battery cover.

[0004] In order to solve the above technical problems, this application is implemented as follows:

[0005] In its first aspect, the present application provides an electronic device comprising a frame, a battery module, a cover, and a polymer protective film. The battery module is disposed within the frame; the cover is disposed on a side of the battery module away from the frame, and the cover is provided with a groove that is recessed toward the exterior of the electronic device, with the notch facing the battery module; the polymer protective film is disposed on a side of the battery module that is close to the cover and is located within the groove.

[0006] An electronic device proposed in the present application includes a frame, a battery module, a cover and a polymer protective film. The battery module is arranged in the frame, and the battery module is pasted in the frame to provide energy for the electronic device to work. The cover is covered on the side of the battery module away from the frame. The frame and the cover are combined to wrap the battery module in the internal space of the electronic device, so that the battery module is not affected by external collisions, and at the same time, the internal space of the electronic device is not invaded by dust, which plays a sealing role. The cover is provided with a groove, which is concave toward the outside of the electronic device, and the notch of the groove faces the battery module, and the groove area can cover the battery module area. A polymer protective film is provided in the groove of the cover, so that when the electronic device is hit by a sharp object, the probability of the cover being punctured is reduced. The polymer protective film can block the collision of sharp objects with the battery module, reduce the impact of external collisions on the battery module, and thereby improve the safety of the battery module of the electronic device. The electronic device's cover is a lightweight, thin fiberglass battery cover. Due to its thinness, the fiberglass battery cover offers limited protection for the battery module. By creating a groove in the battery module area and placing a polymer protective film within the groove, the fiberglass battery cover's puncture resistance is enhanced, systematically addressing the battery module safety issues associated with ultra-thin fiberglass battery covers. Furthermore, by creating a groove in the battery module area and placing a polymer protective film within the groove, the number of fiberglass layers in the cover is reduced without increasing the overall thickness of the electronic device, thereby lowering the cover's manufacturing cost.

DETAILED DESCRIPTION

[0017] The embodiments of the present application will be described in detail below. Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present application and are not to be construed as limiting the present application. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0018] Refer to the following Figures 1 to 6 An electronic device 100 according to some embodiments of the present application is described.

[0019] According to some embodiments of the present application, Figure 1 、 Figure 2 and Figure 3 As shown, an electronic device 100 is provided, comprising a frame 200, a battery module 300, a cover 400, and a polymer protective film 500. The battery module 300 is disposed within the frame 200; the cover 400 is disposed on the side of the battery module 300 away from the frame 200, and the cover 400 is provided with a groove 410 that is recessed toward the exterior of the electronic device 100, with a notch 906 of the groove 410 facing the battery module 300; the polymer protective film 500 is disposed on the side of the battery module 300 that is close to the cover 400 and is located within the groove 410.

[0020] The electronic device 100 proposed in this application includes a frame 200, a battery module 300, a cover 400 and a polymer protective film 500. The battery module 300 is arranged in the frame 200, and the battery module is pasted in the frame 200 to provide energy for the electronic device 100 to operate. The cover 400 covers the side of the battery module 300 away from the frame 200. The frame 200 and the cover 400 are combined to wrap the battery module 300 in the internal space of the electronic device 100, so that the battery module 300 is not affected by external collisions, and at the same time, the internal space of the electronic device 100 is not invaded by dust, thereby playing a sealing role. The cover 400 is provided with a groove 410, which is recessed toward the outside of the electronic device 100, and the notch 906 of the groove 410 faces the battery module 300. The groove 410 area can cover the battery module 300 area. A polymer protective film 500 is provided in the groove 410 of the cover 400, so that when the electronic device 100 is hit by a sharp object, the probability of the polymer protective film 500 and the cover 400 being punctured is reduced. The polymer protective film 500 can block the collision of sharp objects with the battery module 300, reduce the risk of the battery module 300 being hit by external collisions, and thereby improve the safety of the battery module 300 of the electronic device 100. The cover 400 of the electronic device 100 is a lightweight glass fiber battery cover. Because the glass fiber battery cover is very thin, the protective effect on the battery module 300 is limited. By digging a groove in the battery module 300 area and placing the polymer protective film 500 in the groove, the puncture resistance of the glass fiber battery cover is improved, and the safety problem of the battery module 300 caused by the ultra-thin glass fiber battery cover is systematically solved. At the same time, by digging a groove in the battery module 300 area and placing a polymer protective film 500 in the groove, the number of glass fiber layers of the glass fiber battery cover is reduced without increasing the thickness of the entire electronic device 100, thereby reducing the manufacturing cost of the cover body 400.

[0021] In addition, by digging a groove in the battery module 300 area and placing a polymer protective film 500 in the groove, compared with the solution of using the polymer protective film 500 for insert injection molding of the cover 400, the manufacturing cost of the cover 400 provided in this application is significantly reduced, thereby reducing the production cost of the electronic device 100 and improving market competitiveness.

[0022] Furthermore, the electronic device 100 defined in this application utilizes a solution that reduces the number of glass fiber layers in the cover 400 by digging a groove in the battery module 300 region and placing a polymer protective film 500 within the groove. This allows for more efficient heat dissipation from components within the electronic device 100, thereby improving the smoothness of use of the electronic device 100. Furthermore, this more efficient heat dissipation from components within the electronic device 100 extends the service life of the components and thereby enhances the stability of the electronic device 100.

[0023] Furthermore, the electronic device 100 defined in the present application reduces the number of glass fiber layers of the cover 400 by digging a groove in the battery module 300 area and setting a polymer protective film 500 in the groove, making the cover 400 lighter and thus making the entire electronic device 100 lighter.

[0024] Furthermore, the electronic device 100 defined in the present application replaces the solution of using the polymer protective film 500 as insert injection molding for the cover 400 by digging a groove in the battery module 300 area and setting a polymer protective film 500 in the groove, thereby simplifying the production process of the cover 400, improving the production efficiency of the cover 400, and making the product more competitive.

[0025] Furthermore, the electronic device 100 defined in the present application replaces the solution of using the polymer protective film 500 as an insert injection molding for the cover 400 by digging a groove in the battery module 300 area and setting a polymer protective film 500 in the groove. The price of repairing and replacing the cover is lower, which provides a guarantee for after-sales service and makes the product more competitive.

[0026] Furthermore, if Figure 2 As shown, the polymer protective film 500 is adhered to the cover body 400; and / or the polymer protective film 500 is adhered to the battery module 300. Specifically, the polymer protective film 500 is pasted in the groove 410 of the cover body 400, and / or the polymer protective film 500 is pasted on the battery module 300. The polymer protective film 500 has strong puncture resistance, which protects the safety of the electronic module. At the same time, the polymer protective film 500 is pasted in the groove 410 of the cover body 400 and / or on the battery module 300. During assembly, the polymer protective film 500 can be directly pasted without the need to adopt ultra-high molecular weight polyethylene (UPE, Ultra-high molecular Weight Polyethylene) insert injection molding and other processes. This not only ensures the safety of the battery module 300, but also simplifies the assembly process of the electronic device 100, reduces the difficulty of assembly, thereby improving the assembly efficiency and reducing the production cost of the electronic device 100.

[0027] According to some embodiments of the present application, Figure 1 and Figure 2 As shown, optionally, the polymer protective film 500 includes a film body 510 and a first colloid 520. The film body 510 is adhered to the cover 400 and / or the battery module 300 through the first colloid 520.

[0028] In this embodiment, the polymer protective film 500 includes a film body 510 and a first colloid 520. The polymer protective film 500 is adhered to the groove 410 of the cover body 400 and / or adhered to the battery module 300 through the first colloid 520, further simplifying the assembly process of the electronic device 100 and reducing the assembly difficulty.

[0029] At the same time, the polymer protective film 500 is attached to the groove 410 of the cover 400 through the first colloid 520 provided therewith, thereby avoiding increasing the thickness of the entire electronic device 100 and reducing the number of glass fiber layers of the cover 400, thereby reducing the manufacturing cost of the cover 400. According to some embodiments of the present application, such as Figure 1 and Figure 3 As shown, optionally, the cover body 400 includes a main body 420, the main body 420 is provided with a groove 410, the inner wall of the groove 410 includes a bottom wall 412 and a side wall 414, the polymer protective film 500 is attached to the bottom wall 412, and the side wall 414 is inclined relative to the inner surface of the main body 420 in a direction away from the bottom wall 412.

[0030] In this embodiment, the body 420 of the cover 400 is provided with a recess 410. The polymer protective film 500 is attached to the bottom wall 412 of the recess 410. The sidewalls 414 of the recess 410 are inclined relative to the inner surface of the body 420, along and away from the bottom wall 412. The inclined sidewalls 414 within the recess 410 of the cover 400 prevent marks from forming in the recess 410 area, thus resolving the issue of marks on the cover 400 caused by step differences in the electronic device 100 and enhancing the refined appearance of the electronic device 100.

[0031] Furthermore, the side wall 414 of the cover body 400 can adopt an extra-long slope of 1°. By utilizing the transition solution of the side wall 414 of the groove 410 of the cover body 400 adopting an extra-long slope of 1°, the appearance problems such as imprints caused by the step difference of the cover body 400 are solved, thereby improving the exquisiteness of the appearance of the electronic device 100, making the product appearance more beautiful, and improving the competitiveness of the product.

[0032] According to some embodiments of the present application, Figure 1 and Figure 3 As shown, optionally, the angle between the side wall 414 and the inner surface of the cover body 400 is greater than or equal to 0.5 degrees and less than or equal to 5 degrees.

[0033] In this embodiment, the angle between the sidewall 414 of the cover 400 and the inner surface of the cover 400 is greater than or equal to 0.5 degrees and less than or equal to 5 degrees, so that the angle of the sidewall 414 of the cover 400 is not likely to be too large or too small. If the angle of the sidewall 414 of the cover 400 is too large, the cover 400 will have a step difference, and the cover 400 will have appearance problems such as marks, which makes the provision of the inclined sidewall 414 in the recess 410 of the cover 400 meaningless. If the angle of the sidewall 414 of the cover 400 is too small, the area reserved for the bottom wall 412 of the recess 410 of the cover 400 is reduced, and the polymer protective film 500 attached to the bottom wall 412 of the recess 410 cannot fully cover the battery module 300 area. Consequently, the polymer protective film 500 cannot ensure the safety of the battery module 300, making the solution of digging a groove in the battery module 300 area and placing the polymer protective film 500 in the groove meaningless.

[0034] According to some embodiments of the present application, Figure 3 As shown, the cover 400 optionally includes a first boss 430 and a second adhesive 440. The first boss 430 is provided on the body 420, located on a side of the body 420 close to the frame 200; the second adhesive 440 is provided on the first boss 430, and the first boss 430 is bonded to the frame 200 through the second adhesive 440.

[0035] In this embodiment, the cover 400 includes a first boss 430 and a second adhesive 440. The first boss 430 is disposed on the body 420, near one side of the frame 200. The second adhesive 440 is disposed on the first boss 430. The second adhesive 440 is used to bond the frame 200 to the first boss 430, and further to bond the frame 200 to the cover 400. The bonding of the frame 200 and the cover 400 seals the interior of the electronic device 100, protecting it from dust and improving its stability. Furthermore, the second adhesive 440 can be thickened or thinned, allowing the cover 400 to be compatible with the frame 200. Design optimizations are implemented on both the inside and outside of the cover 400. The inside of the cover 400 is uniformly raised, and the thicker second adhesive 440 is used for bonding to ensure alignment of the inside of the cover 400 with the inside of the frame 200. On the outside of the cover 400, the cover 400 is designed with uneven thickness, with the outer edge of the cover 400 being thicker, bringing the thickness of the outer edge of the cover 400 closer to the thickness of the outer edge of the frame 200. Furthermore, the cover 400's exterior design is adjusted so that the thickness gradually decreases towards the inside. A polymer protective film 500 is applied to the thinned area, achieving the desired thickness reduction for the entire electronic device 100. This also addresses the safety concerns of the battery module 300 of the electronic device 100 and the issue of scratches at the junction of the frame 200 and the cover 400.

[0036] Furthermore, there are multiple first bosses 430 and multiple second colloids 440, with the multiple first bosses 430 positioned on a side proximal to the frame 200. The multiple first bosses 430 and multiple second colloids 440 are used to bond the frame 200 to the cover 400, thereby improving the sealing of the interior of the electronic device 100 and enhancing the stability of the electronic device 100. Furthermore, the multiple first bosses 430 and multiple second colloids 440 bond the frame 200 to the cover 400, further strengthening the bond between them. This reduces the risk of separation between the frame 200 and the cover 400 when the electronic device is bumped, thereby enhancing the competitiveness of the electronic device 100.

[0037] The first boss 430 is provided on the cover 400 and can be integrally formed with the cover 400. During the production of the cover 400, the first boss 430 and the cover 400 are formed into an integral structure by injection molding, so that the internal structure of the electronic device 100 is more solid. Figure 3 As shown, optionally, the cover 400 further includes a first transition portion 450 , which is arranged around the first boss 430 and extends obliquely from the surface of the first boss 430 toward the inner surface of the body 420 .

[0038] In this embodiment, the cover body 400 also includes a first transition portion 450, which is arranged around the first boss 430 and extends obliquely from the surface of the first boss 430 to the inner surface of the main body 420, so that the first boss 430 of the cover body 400 has a bevel transition around it, avoiding the imprint problem caused by the setting of the first boss 430 on the cover body 400, improving the aesthetics of the cover body 400, and making the appearance of the electronic device 100 more refined and delicate.

[0039] The first transition portion 450 is disposed on the cover 400 and may be integrally formed with the cover 400. During the production of the cover 400, the first transition portion 450 and the cover 400 are formed into a single unitary structure through injection molding, thereby strengthening the internal structure of the electronic device 100, further preventing the occurrence of print marks, and improving the aesthetics of the cover 400, giving the electronic device 100 a more refined and sophisticated appearance.

[0040] According to some embodiments of the present application, Figure 3 、 Figure 4 and Figure 5As shown, optionally, the main body 420 is provided with a first opening 422, and the cover body 400 also includes a second boss 460, which is provided on the main body 420, located on the side of the main body 420 close to the frame 200, and arranged around the first opening 422; the electronic device 100 also includes a first bracket 600, a first decorative ring 700 and a flash cover 800; the first bracket 600 is bonded to the second boss 460; the first decorative ring 700 is located in the first opening 422 and is connected to the first bracket 600; the flash cover 800 is provided on the first decorative ring 700.

[0041] In this embodiment, the main body 420 is provided with a first opening 422, and the cover 400 further includes a second boss 460. The second boss 460 is located on the side of the main body 420 near the frame 200 and is arranged around the first opening 422. The electronic device 100 further includes a first bracket 600, a first decorative ring 700, and a flash cover 800. The first bracket 600 is attached to the second boss 460 using double-sided tape. The first decorative ring 700 is positioned at the first opening 422 and is fixedly connected to the first bracket 600. The flash cover 800 is also adhered to the cover 400 using double-sided tape. However, due to the ultra-thin design of the cover 400, existing materials cannot be used with the cover 400 specified in this application. To achieve universal material compatibility for the electronic device 100, the cover 400 is provided with a second boss 460, allowing existing materials to be used with the cover 400 specified in this application, thereby enhancing the competitiveness of the cover 400.

[0042] The second boss 460 is provided on the cover 400 and can be integrally formed with the cover 400. During the production of the cover 400, the second boss 460 and the cover 400 are formed into an integral structure by injection molding, making the internal structure of the electronic device 100 more solid.

[0043] Furthermore, to allow the cover 400 of the electronic device 100 to share the same surface as the frame 200, the inner surface of the fiberglass battery cover is raised compared to the glass version. To allow the decorative ring inner bracket, inner bracket double-sided tape, flash lamp cover, lampshade decorative ring, and lampshade double-sided tape to be shared, the inner surface of the fiberglass battery cover in the rear camera and flash area is partially glued to ensure it is flush with the inner surface of the glass version. A gradual transition is required around the step of the fiberglass battery cover to avoid the problem of imprinting. This allows the existing materials to be used in the cover 400 defined in this application, improving the competitiveness of the cover 400. The frame 200 can be the main surface of the electronic device 100.

[0044] According to some embodiments of the present application, Figure 3 and Figure 5 As shown, optionally, the cover 400 further includes a second transition portion 470 . The second transition portion 470 is arranged around the second boss 460 and extends obliquely from the surface of the second boss 460 toward the inner surface of the body 420 .

[0045] In this embodiment, the cover body 400 also includes a second transition portion 470, which is arranged around the second boss 460 and extends obliquely from the surface of the second boss 460 to the inner surface of the main body 420, so that the second boss 460 of the cover body 400 has a bevel transition around it, avoiding the imprint problem caused by the setting of the second boss 460 on the cover body 400, improving the aesthetics of the cover body 400, and making the appearance of the electronic device 100 more refined and delicate.

[0046] The second transition portion 470 is disposed on the cover 400 and may be integrally formed with the cover 400. During the production of the cover 400, the second transition portion 470 and the cover 400 are formed into a single unit through injection molding, thereby strengthening the internal structure of the electronic device 100, further preventing the occurrence of print marks, and improving the aesthetics of the cover 400, giving the electronic device 100 a more refined and sophisticated appearance.

[0047] According to some embodiments of the present application, Figure 3 、 Figure 4 and Figure 5 As shown, optionally, the main body 420 is provided with a second opening 424, and the cover body 400 also includes a third boss 480, which is provided on the main body 420, located on the side of the main body 420 close to the frame 200, and arranged around the second opening 424; the electronic device 100 also includes a second bracket 602, a second decorative ring 702 and a camera cover 802; the second bracket 602 is bonded to the third boss 480; the second decorative ring 702 is located in the second opening 424 and is connected to the second bracket 602; the camera cover 802 is provided on the second decorative ring 702.

[0048] In this embodiment, the main body 420 is provided with a second opening 424, and the cover 400 also includes a third boss 480. The third boss 480 is located on the side of the main body 420 near the frame 200 and is arranged around the second opening 424. The electronic device 100 also includes a second bracket 602, a second decorative ring 702, and a camera cover 802. The second bracket 602 is positioned by positioning posts and the second decorative ring 702 and is fixed to the third boss 480 using double-sided tape. The second decorative ring 702 is provided in the second opening 424 and is connected and fixed to the second bracket 602. However, due to the ultra-thin design of the cover 400, existing materials cannot be used with the cover 400 specified in this application. To achieve universal material compatibility for the electronic device 100, the cover 400 is provided with a third boss 480 structure, allowing existing materials to be used with the cover 400 specified in this application, thereby improving the competitiveness of the cover 400.

[0049] The third boss 480 is provided on the cover 400 and can be integrally formed with the cover 400. During the production of the cover 400, the third boss 480 and the cover 400 are formed into an integral structure by injection molding, making the internal structure of the electronic device 100 more solid.

[0050] Furthermore, in order to achieve the sharing of the cover 400 of the electronic device 100 with the main body, the inner surface of the fiberglass battery cover is raised compared to the glass version. In order to achieve the sharing of the inner bracket of the decorative ring, the double-sided tape of the inner bracket, the flash lamp cover, the lamp cover decorative ring and the double-sided tape of the lamp cover, the inner surface of the fiberglass battery cover in the rear camera and flash area is partially glued to make it flush with the inner surface of the glass version. The step circle of the fiberglass battery cover needs to be transitioned to avoid the problem of imprints, thereby achieving that the original material can be used on the cover 400 specified in this application, thereby improving the competitiveness of the cover 400.

[0051] According to some embodiments of the present application, Figure 2 、 Figure 3 and Figure 6 As shown, optionally, the cover 400 further includes a third transition portion 490 . The third transition portion 490 is arranged around the third boss 480 and extends obliquely from the surface of the third boss 480 toward the inner surface of the body 420 .

[0052] In this embodiment, the cover body 400 also includes a third transition portion 490, which is arranged around the third boss 480 and extends obliquely from the surface of the third boss 480 to the inner surface of the main body 420, so that the third boss 480 of the cover body 400 has a bevel transition around it, avoiding the imprint problem caused by the setting of the third boss 480 on the cover body 400, improving the aesthetics of the cover body 400, and making the appearance of the electronic device 100 more refined and delicate.

[0053] The third transition portion 480 is disposed on the cover 400 and may be integrally formed with the cover 400. During the production of the cover 400, the third transition portion 480 and the cover 400 are formed into a single unitary structure through injection molding, thereby strengthening the internal structure of the electronic device 100, further preventing the occurrence of print marks, and improving the aesthetics of the cover 400, giving the electronic device 100 a more refined and sophisticated appearance.

[0054] According to some embodiments of the present application, Figure 1 and 6 As shown, optionally, the thickness of the cover body 400 decreases from the edge of the cover body 400 to the middle of the cover body 400.

[0055] In this embodiment, the thickness of the cover body 400 decreases from the edge of the cover body 400 to the middle of the cover body 400. By utilizing the unequal thickness design of the cover body 400, the edge of the cover body 400 gradually thickens, which adjusts the appearance of the electronic device 100 while enabling covers 400 of different thicknesses to share the frame body 200, so that the junction of the cover body 400 and the frame body 200 is at the same height, which will not scratch the user's hands during use, thereby improving the user experience.

[0056] Furthermore, when the same prototype project uses covers 400 of different thicknesses (or processes), considering cost factors, the covers 400 have to share the main body, and the compatibility of the thickness of the whole machine and the appearance of the scratches needs to be achieved. The ultra-thin glass fiber battery cover design provided in this application is thinner than the commonly used glass battery cover. To achieve compatibility between the cover 400 and the main body, the design can be optimized from the inside and outside dimensions of the cover 400. The inner surface of the inside is evenly raised, aligned with the inner side of the main body, and bonded with thicker double-sided tape; on the outside, through the unequal thickness design of the glass fiber battery cover, the outer edge is thicker, close to the thickness of the glass battery cover edge, and the appearance is adjusted at the same time. The thickness has been thinned when gradually changing to the inside, realizing the demand for the ultimate design of the thickness of the whole machine, and also solving the scratching problem at the junction of the cover 400 and the main body, thereby improving the user experience.

[0057] According to some embodiments of the present application, Figure 6 As shown, optionally, the cover 400 is a fiberglass cover; and / or the polymer protective film 500 is a polyethylene protective film.

[0058] In this embodiment, the cover 400 is made of fiberglass. Fiberglass allows for an ultra-thin cover 400, which is cost-effective and meets the ultimate goal of reducing the thickness of the cover 400. The polymer protective film 500 is a polyethylene protective film. Polyethylene protective film is a high molecular weight polymer with strong resistance to puncture by sharp objects. It provides strong protection for the battery module 300 and improves the safety of the battery module 300 in the electronic device 100.

[0059] Furthermore, the polymer protective film 500 defined in the present application is not only a polyethylene protective film, but can also be a new functional material that can better protect the safety of the battery module 300.

[0060] Furthermore, the electronic device 100 defined in this application is not only applicable to mobile phones, but also to electronic products such as computers, smart wearables, car screens, refrigerator screens, and drones.

[0061] Furthermore, the battery module 300 is adhered to the battery slot of the frame 200 by double-sided tape, and is used to provide energy for the operation of the entire machine, such as the main board 904, speakers 902 and other accessories. It is covered with UPE and fiberglass battery cover on the top and screen 900 on the bottom.

[0062] Furthermore, the present application provides a lightweight and thin glass fiber battery cover structural design scheme, which utilizes clever unequal thickness, partial grooves, partial bosses and ultra-large slope gradient structural design to systematically solve problems such as battery safety, middle frame (or main frame) sharing, cost optimization and improved appearance refinement, and achieve an extremely lightweight and thin battery cover design, thereby achieving the lightweight of the entire machine, improving the user experience, and also taking into account battery safety issues.
