Description

Technical Field

[0001] This utility model relates to the field of electronic equipment technology, and in particular to a quick-release structure for a battery cover and an electronic device thereof. Background Technology

[0002] Currently, with the rapid development of electronic products, consumers have increasingly higher requirements for the functionality, reliability, and appearance of electronic products. Electronic devices need to have IP68 waterproof capabilities, which makes the bonding between the battery cover and the mid-frame increasingly reliable. Existing methods typically use simple adhesive on the battery cover's back to bond the mid-frame and the battery cover, requiring only sufficient adhesion. However, improvements in the quality of existing battery cover adhesives have resulted in very high adhesion, making it difficult to disassemble the mid-frame and battery cover. This often requires high-temperature heating and the use of tools for disassembly, leading to low efficiency and the risk of the battery cover cracking or being damaged during the process. Utility Model Content

[0003] In response to the problems raised in the background art, the purpose of this utility model is to propose a quick-release structure for a battery cover and an electronic device. The insulated battery cover is removed from the conductive frame more quickly and easily, with high removal efficiency. The insulated battery cover will not be damaged during the removal process, thus solving the technical problems of existing battery covers being difficult to remove from the frame, having low removal efficiency, and being easily damaged during the removal process.

Furthermore, features defined with "first" and "second" may explicitly or implicitly include one or more of these features, used to distinguish descriptive features, without any order or emphasis.

[0027] like Figures 1 to 4 As shown, a quick-release structure for a battery cover includes a conductive frame 1, an insulating battery cover 2, a camera conductive decorative part 3, an electro-adhesive layer 4, and a conductive layer 5.

[0028] The conductive frame 1 is provided with an open mounting groove 11, the insulating battery cover 2 is installed in the mounting groove 11, and the side wall of the insulating battery cover 2 is fitted to the inner side wall of the conductive frame 1.

[0029] The camera conductive decorative component 3 is installed on the insulating battery cover 2, and the camera conductive decorative component 3 has a protrusion 31 and a surrounding edge 32. The protrusion 31 protrudes outward relative to the insulating battery cover 2 and is exposed on the outer surface of the insulating battery cover 2, and the surrounding edge 32 is located on the inner side of the insulating battery cover 2.

[0030] The conductive frame 1 has an adhesive surface 12 in the mounting groove 11, the insulating battery cover 2 has a connecting surface 21 facing the conductive frame 1, the electro-adhesive layer 4 has a first adhesive surface 41 and a second adhesive surface 42 disposed opposite to each other, the first adhesive surface 41 is bonded to the adhesive surface 12, one end of the conductive layer 5 is disposed between the second adhesive surface 42 and the connecting surface 21, and the other end of the conductive layer 5 is connected to the edge portion 32.

[0031] The conductive frame 1 is the main support structure for an electronic device with a camera, which can be a mobile phone or a tablet computer. In the electronic device with a camera, the insulating battery cover 2 is installed in the mounting groove 11 of the conductive frame 1. Since the side wall of the insulating battery cover 2 is fitted to the inner side wall of the conductive frame 1, the adhesive joint between the insulating battery cover 2 and the conductive frame 1 is located inside the conductive frame 1 (i.e., inside the mounting groove 11). Once the insulating battery cover 2 is glued to the conductive frame 1, it is difficult to remove the insulating battery cover 2 from the conductive frame 1.

[0032] This invention utilizes the electro-adhesive layer 4 and the conductive layer 5. The insulating battery cover 2 is bonded to the conductive frame 1 via the electro-adhesive layer 4. When the insulating battery cover 2 needs to be removed from the conductive frame 1, the conductive frame 1 is connected to the negative terminal of an external power supply, and the protruding portion 31 of the camera conductive decorative part 3 is connected to the positive terminal of the external power supply. Since one end of the conductive layer 5 is located between the second adhesive surface 42 and the connecting surface 21, and the other end of the conductive layer 5 is connected to the surrounding edge 32... When connected, the second adhesive surface 42 of the electro-adhesive layer 4 is connected to the edge portion 32 through the conductive layer 5. Current can flow from the edge portion 32 of the conductive decorative part 3 of the camera to the conductive layer 5, and then through the conductive layer 5 to the second adhesive surface 42 of the electro-adhesive layer 4. An electric field is formed on the second adhesive surface 42 of the electro-adhesive layer 4. Since the conductive frame 1 itself is conductive, when the conductive frame 1 is connected to an external power source, an electric field is formed on the first adhesive surface 41 of the electro-adhesive layer 4. After the conductive frame 1 and the protrusion 31 are connected to the two poles of an external power source and energized, an electric field is formed on the first adhesive surface 41 and the second adhesive surface 42 of the electro-adhesive layer 4. This causes the randomly distributed mobile electrolytes in the electro-adhesive layer 4 to migrate directionally under the influence of the electric field. Under the influence of the electric field, cations in the electro-adhesive layer 4 move towards the negative electrode side, and anions move towards the positive electrode side. The cations undergo an electrochemical reaction on the negative electrode side, which reduces the adhesive force between the first adhesive surface 41 of the electro-adhesive layer 4 and the adhesive surface 12 of the conductive frame 1. This allows for rapid peeling of the electro-adhesive layer 4 from the conductive frame 1, thereby removing the insulating battery cover 2 from the conductive frame 1. The removal efficiency is high, and the insulating battery cover 2 is not damaged during the removal process. When no power is applied, the insulating battery cover 2 is stably bonded to the conductive frame 1 by the electro-adhesive layer 4.

[0033] Specifically, the electro-tack layer 4 uses an existing electro-tack adhesive.

[0034] Furthermore, since the battery cover is typically made of insulating material, while the mid-frame is typically made of conductive material, the conductive mid-frame 1, being conductive itself, can generate an electric field at the first adhesive surface 41. By providing the conductive layer 5, the second adhesive surface 42 of the electro-adhesive layer 4 is connected to the edge portion 32 through the conductive layer 5. On the side of the insulating battery cover 2, the electrode current flows sequentially from the camera conductive decorative part 3 to the conductive layer 5 and the second adhesive surface 42, thereby generating an electric field at the first adhesive surface 41 and the second adhesive surface 42 of the electro-adhesive layer 4. In this quick-disassembly structure, since the sidewall of the insulating battery cover 2 is fitted to the inner sidewall of the conductive frame 1, it is difficult for an external power supply to enter the mounting groove 11 and connect with the conductive layer 5 from between the sidewall of the insulating battery cover 2 and the inner sidewall of the conductive frame 1. The camera conductive decorative part 3, which is provided with the protrusion 31, protrudes outward relative to the insulating battery cover 2 and is exposed on the outer surface of the insulating battery cover 2, making it easy to connect with an external power supply. After connecting with the external power supply through the protrusion 31, the second adhesive surface 42 of the electro-adhesive layer 4 is connected to the edge portion 32 through the conductive layer 5, thereby enabling the electro-adhesive layer 4 to be peeled off from the conductive frame 1.

[0035] The quick-release structure of this battery cover utilizes the conductive decorative part 3 of the camera to achieve the formation of an electric field on the side of the insulating battery cover 2 (i.e., the second adhesive surface 42) of the electro-adhesive layer 4, making it faster and easier to remove the insulating battery cover 2 from the conductive frame 1, with high removal efficiency. The insulating battery cover 2 will not be damaged during the removal process, thus solving the technical problems of existing battery covers being difficult to remove from the frame, having low removal efficiency, and being easily damaged during the removal process.

[0036] To further explain, the conductive frame 1 has an adhesive step 13 in the mounting groove 11, and the adhesive surface 12 is disposed on the adhesive step 13, with the adhesive surface 12 being disposed opposite to the connecting surface 21.

[0037] By setting the adhesive step 13, the insulating battery cover 2 is bonded to the conductive frame 1 through the adhesive step 13, and the bonding stability is high when no power is applied.

[0038] To further explain, the surrounding edge 32 extends toward the surface of the insulating battery cover 2.

[0039] By extending the edge portion 32 toward the surface of the insulating battery cover 2, the conductive layer 5 can be connected to the extended surface of the edge portion 32, ensuring that current can be conducted through the camera conductive decorative part 3 and the conductive layer 5 to the second adhesive surface 42 of the electro-adhesive layer 4.

[0040] Specifically, the conductive frame 1 is made of metal, the insulating battery cover 2 is made of glass, and the camera conductive decorative component 3 is made of metal.

[0041] It should be noted that, in the complete machine state, the outer surface of the conductive middle frame 1 is usually anodized. The oxide layer can be removed by peeling off the inner wall of the card tray hole or the inner wall of the button hole provided in the conductive middle frame 1 to achieve the connection with the electrode of the external power supply.

[0042] It should be noted that the outer surface of the camera conductive decorative component 3 is also typically anodized. Before connecting the protrusion 31 of the camera conductive decorative component 3 to an external power source, the oxide layer on the outer surface of the protrusion 31 can be scraped off with tweezers to achieve connection with the electrode. Since the contact area between the edge portion 32 and the conductive layer 5 is an internal structure, the outer surface of the edge portion 32 typically does not have an oxide layer, and this will not affect the current conduction between the edge portion 32 and the conductive layer 5. Even if the outer surface of the edge portion 32 also has an oxide layer, laser engraving can be performed at the contact area between the edge portion 32 and the conductive layer 5 to form a laser-engraved area. The laser-engraved area will not affect the current conduction between the edge portion 32 and the conductive layer 5.

[0043] Specifically, the insulating battery cover 2 has a through hole 22, the camera conductive decorative part 3 is installed in the through hole 22, and the surrounding part 32 is arranged parallel to the insulating battery cover 2.

[0044] like Figure 1 and Figure 2 As shown, in one embodiment of the present invention, the conductive layer 5 is a conductive adhesive, and the conductive layer 5 is at least partially bonded between the surrounding portion 32 and the second adhesive surface 42. The conductive layer 5 disposed between the second adhesive surface 42 and the connecting surface 21 is in communication with the conductive layer 5 bonded between the surrounding portion 32 and the second adhesive surface 42.

[0045] Specifically, in this embodiment, the conductive layer 5 is a conductive adhesive, and the conductive layer 5 is entirely attached to the entire second adhesive surface 42. The conductive layer 5 has a continuous layered structure. When the protrusion 31 of the camera conductive decorative part 3 is connected to an external power source, current can flow from the camera conductive decorative part 3 to the conductive layer 5 bonded between the edge portion 32 and the second adhesive surface 42, and then through the conductive layer 5 bonded between the edge portion 32 and the second adhesive surface 42 to the conductive layer 5 disposed between the second adhesive surface 42 and the connecting surface 21, thereby forming an electric field on the second adhesive surface 42.

[0046] Preferably, the thickness of the conductive layer 5 is 0.05 to 0.1 mm.

[0047] In this embodiment, the conductive layer 5 is a conventional conductive adhesive. If the thickness of the conductive layer 5 is too thick, it may affect the adhesion of the conductive layer 5 to the connecting surface 21.

[0048] like Figure 3 and Figure 4 As shown, in another embodiment of this utility model, the conductive layer 5 is a metal conductive film. The conductive layer 5 is at least partially disposed between the perimeter portion 32 and the connecting surface 21. The conductive layer 5 disposed between the second adhesive surface 42 and the connecting surface 21 is in communication with the conductive layer 5 disposed between the perimeter portion 32 and the connecting surface 21.

[0049] Specifically, in this embodiment, the conductive layer 5 is a metal conductive film, and the conductive layer 5 is integrally plated on the connecting surface 21. The conductive layer 5 has a continuous layered structure. When the protrusion 31 of the camera conductive decorative part 3 is connected to an external power source, current can flow from the camera conductive decorative part 3 to the conductive layer 5 bonded between the edge portion 32 and the connecting surface 21, and then flow through the conductive layer 5 disposed between the edge portion 32 and the connecting surface 21 to the conductive layer 5 disposed between the second adhesive surface 42 and the connecting surface 21, thereby forming an electric field on the second adhesive surface 42.

[0050] Furthermore, the quick-release structure of the battery cover also includes a conductive adhesive layer 6, which is disposed between the conductive layer 5 and the surrounding edge portion 32.

[0051] Specifically, the conductive adhesive layer 6 uses existing conductive adhesive. By providing the conductive adhesive layer 6 between the conductive layer 5 and the surrounding portion 32, the conductive adhesive layer 6 is sandwiched between the surrounding portion 32 and the conductive layer 5 (in this embodiment, a metal conductive film). Due to the certain tolerance of the conductive adhesive, it can prevent poor contact between the surrounding portion 32 and the conductive layer 5, resulting in better contact between the surrounding portion 32 and the conductive layer 5.

[0052] To further explain, the thickness of the conductive layer 5 is 15–25 μm.

[0053] In this embodiment, the thickness of the conductive layer 5 is preferably 20 μm.

[0054] In this embodiment, the conductive layer 5 is an existing metal conductive film. If the thickness of the conductive layer 5 is too thin, the conductivity will be poor. If the thickness of the conductive layer 5 is too thick, it will easily fall off and affect the overall thickness of the bonding area.

[0055] To further explain, the electro-adhesive layer 4 includes a first adhesive portion 43, a connecting portion 44, and a second adhesive portion 45. At least a portion of the first adhesive portion 43 is disposed between the adhesive surface 12 and the connecting surface 21. One end of the connecting portion 44 is connected to the first adhesive portion 43, and the other end of the connecting portion 44 is connected to the second adhesive portion 45. At least a portion of the second adhesive portion 45 is disposed on the side of the edge portion 32 facing away from the insulating battery cover 2.

[0056] like Figure 2 As shown, in one embodiment of this utility model, the conductive layer 5 is continuously bonded to the second adhesive surface 42 of the first adhesive portion 43, the connecting portion 44 and the second adhesive portion 45. The conductive layer 5 is disposed between the second adhesive portion 45 and the surrounding portion 32, which enables current to flow from the camera conductive decorative part 3 to the conductive layer 5, and then to form an electric field on the second adhesive surface 42 through the conductive layer 5.

[0057] like Figure 4 As shown, in another embodiment of this utility model, the conductive layer 5 is continuously disposed between the first adhesive portion 43 and the connecting surface 21 and between the surrounding portion 32 and the connecting surface 21, which enables current to flow from the camera conductive decorative part 3 to the conductive layer 5, and then the conductive layer 5 to form an electric field on the second adhesive surface 42.

[0058] Preferably, the thickness of the electro-adhesive layer 4 is 0.2 to 0.3 mm.

[0059] The thickness of the electro-adhesive layer 4 is within this range, which can ensure the bonding effect. Moreover, the electro-adhesive layer 4 within this thickness range contains a certain amount of cations and anions, which can ensure rapid peeling between the electro-adhesive layer 4 and the conductive middle frame 1 after energizing and forming an electric field on the first adhesive surface 41 and the second adhesive surface 42 of the electro-adhesive layer 4.

[0060] Preferably, the thickness of the electro-adhesive layer 4 is 0.3 mm.

[0061] An electronic device includes a quick-release structure for the battery cover.

[0062] The electronic device is an electronic device with a camera, such as a mobile phone or a tablet computer.

[0063] The electronic device allows for easy removal of the insulating battery cover 2 from the conductive frame 1.

[0064] The technical principles of this utility model have been described above with reference to specific embodiments. These descriptions are merely for explaining the principles of this utility model and should not be construed as limiting the scope of protection of this utility model in any way. Based on this explanation, those skilled in the art can readily conceive of other specific embodiments of this utility model without any inventive effort, and these embodiments will all fall within the scope of protection of this utility model.
