[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 a simple adhesive backing to bond the mid-frame and battery cover, and the bonding location is usually inside the mid-frame. This makes it difficult for operators to remove the battery cover from the mid-frame, requiring high-temperature heating and the use of tools for disassembly, which is inconvenient and inefficient. Utility Model Content

[0003] In response to the problems raised in the background technology, the purpose of this utility model is to propose a convenient battery cover quick-release structure and electronic device. The conductive layer is easy to connect to the external power supply, making the disassembly operation convenient, fast and efficient. It solves the technical problem that the existing battery cover is usually glued to the middle frame inside the middle frame, which makes it difficult to remove the battery cover from the middle frame, resulting in inconvenient disassembly operation and low disassembly efficiency.

[0004] The above-mentioned technical objective of this utility model is achieved through the following technical solution:

[0005] A convenient and quick-release battery cover structure includes a conductive frame, an insulating battery cover, an electro-adhesive layer, and a conductive layer.

[0006] The conductive frame is provided with an open mounting groove, and the insulating battery cover is installed in the mounting groove;

[0007] The conductive layer includes a receiving part and a conducting part. An open receiving gap is provided between the side wall of the conductive frame and the side wall of the insulating battery cover. The receiving part is disposed in the receiving gap.

[0008] The conductive frame has an adhesive surface in the mounting groove, the insulating battery cover has a connecting surface facing the conductive frame, the electro-adhesive layer has a first adhesive surface and a second adhesive surface disposed opposite to each other, the first adhesive surface is bonded to the adhesive surface, and the conductive part is disposed between the second adhesive surface and the connecting surface.

[0009] Optionally, the horizontal plane at the upper end of the conductive frame is at the same height as the horizontal plane at the upper end of the insulating battery cover, and the end of the contact portion away from the conductive portion extends between the upper end of the conductive frame and the upper end of the insulating battery cover.

[0010] Optionally, the quick-release battery cover structure further includes an insulating layer disposed between the electrical contact portion and the inner sidewall of the conductive frame.

[0017] Compared with the prior art, the embodiments of this utility model have the following beneficial effects:

[0018] The aforementioned convenient quick-release battery cover structure features an open electrical connection gap between the side wall of the conductive frame and the side wall of the insulating battery cover, with the electrical connection portion of the conductive layer located within this gap. This allows the operator to easily connect the electrodes of an external power source to the electrical connection portion. The current then flows through the electrical connection portion to the conductive portion, thereby creating an electric field between the second and first adhesive surfaces. The easy connection between the conductive layer and the external power source facilitates convenient, quick, and efficient disassembly.

[0026] like Figures 1 to 4 As shown, a convenient battery cover quick-release structure includes a conductive middle frame 1, an insulating battery cover 2, an electro-adhesive layer 3, and a conductive layer 4.

[0027] The conductive frame 1 is provided with an open mounting groove 11, and the insulating battery cover 2 is installed in the mounting groove 11;

[0028] The conductive layer 4 includes a receiving part 41 and a conducting part 42. An open receiving gap 5 is provided between the side wall of the conductive frame 1 and the side wall of the insulating battery cover 2. The receiving part 41 is disposed in the receiving gap 5. One end of the receiving part 41 is connected to the outside, and the other end of the receiving part 41 is connected to the conducting part 42.

[0029] The conductive frame 1 has an adhesive surface 12 in the mounting groove 11, the insulating battery cover 2 has a connecting surface facing the conductive frame 1, the electro-adhesive layer 3 has a first adhesive surface 31 and a second adhesive surface 32 disposed opposite to each other, the first adhesive surface 31 is bonded to the adhesive surface 12, and the conductive part 42 is disposed between the second adhesive surface 32 and the connecting surface 21.

[0030] The conductive frame 1 is the main support structure of the electronic device, which can be a mobile phone, tablet computer, laptop computer, smartwatch, smart bracelet, or other electronic device. Since the adhesive surface 12 is located within the mounting groove 11, the insulating battery cover 2 is installed in the mounting groove 11, and the first adhesive surface 31 is bonded to the adhesive surface 12. The insulating battery cover 2 is bonded to the conductive frame 1 through the electro-adhesive layer 3. The bonding point between the insulating battery cover 2 and the conductive frame 1 is located inside the conductive frame 1. Once the insulating battery cover 2 is bonded to the conductive frame 1, it is difficult to detach the bonding point from inside the conductive frame 1.

[0031] This invention utilizes the electro-adhesive layer 3 and the conductive layer 4 to bond the insulating battery cover 2 to the conductive frame 1 via the electro-adhesive layer 3. The conductive layer 4 includes a contact portion 41 and a conductive portion 42. The contact portion 41 is located within a contact gap 5 between the side wall of the conductive frame 1 and the side wall of the insulating battery cover 2. The contact gap 5 is open, allowing one end of the contact portion 41 to communicate with the outside, while the other end of the contact portion 41 is connected to the conductive portion 42. The conductive portion 42 is located between the second adhesive surface 32 and the connecting surface 21. When it is necessary to remove the insulating battery cover 2 from the conductive frame 1, connect the conductive frame 1 to the negative terminal of the external power supply, and connect the positive terminal of the external power supply to the end of the contact part 41 that is connected to the outside. The current flows from the contact part 41 to the conductive part 42, and then through the conductive part 42 to the second adhesive surface 32 of the electro-adhesive layer 3. An electric field is formed on the second adhesive surface 32 of the electro-adhesive layer 3. Since the conductive frame 1 itself is conductive, when the conductive frame 1 is connected to the electrode of the external power supply, an electric field is formed on the first adhesive surface 31 of the electro-adhesive layer 3. That is, when the conductive frame 1 is connected to the electrode of the external power supply, an electric field is formed on the first adhesive surface 31 of the electro-adhesive layer 3. After the receiving part 41 is connected to the two poles of the external power supply and energized, it can form an electric field on the first adhesive surface 31 and the second adhesive surface 32 of the electro-adhesive layer 3. This causes the randomly distributed mobile electrolytes in the electro-adhesive layer 3 to migrate directionally under the action of the electric field. Under the action of the electric field, the cations in the electro-adhesive layer 3 move towards the negative electrode side, and the anions move towards the positive electrode side. The cations undergo an electrochemical reaction on the negative electrode side, which reduces the adhesion between the first adhesive surface 31 of the electro-adhesive layer 3 and the adhesive surface 12 of the conductive middle frame 1, thereby achieving rapid peeling between the electro-adhesive layer 3 and the conductive middle frame 1.

[0032] Specifically, the electro-adhesive layer 3 uses an existing electro-adhesive adhesive, and the insulating battery cover 2 is stably bonded to the conductive frame 1 through the electro-adhesive layer 3 when no power is applied.

[0033] To further explain, since the battery cover is usually made of insulating material and the middle frame is usually made of conductive material, this quick-release battery cover structure provides an open electrical connection gap 5 between the side wall of the conductive middle frame 1 and the side wall of the insulating battery cover 2, and the electrical connection part 41 of the conductive layer 4 is located in the electrical connection gap 5. This allows the operator to easily connect the electrode of the external power supply to the electrical connection part 41, and the current then flows through the electrical connection part 41 to the conductive part 42, thereby forming an electric field on the second adhesive surface 32 and the first adhesive surface 31. The connection between the conductive layer 4 and the external power supply is convenient, making the disassembly operation convenient, fast, and efficient. This solves the technical problem that the existing battery cover is usually bonded to the middle frame inside the middle frame, making it difficult to remove the battery cover from the middle frame, resulting in inconvenient disassembly and low disassembly efficiency.

[0034] Preferably, the horizontal plane at which the upper end face of the conductive middle frame 1 is located is at the same height as the horizontal plane at which the upper end face of the insulating battery cover 2 is located, and the end of the power receiving part 41 away from the conductive part 42 extends between the upper end face of the conductive middle frame 1 and the upper end face of the insulating battery cover 2.

[0035] By extending the end of the contact portion 41 away from the conductive portion 42 to between the upper end face of the conductive frame 1 and the upper end face of the insulating battery cover 2, the end of the contact portion 41 that is connected to the outside is exposed on the surface of the conductive frame 1 and the insulating battery cover 2 and is flush with the upper end face of the conductive frame 1 and the insulating battery cover 2. This makes it easier to connect the electrodes directly to the upper end face of the contact portion 41 when connecting an external power source to the end of the contact portion 41 that is connected to the outside. This further simplifies the electrode connection operation, as it does not require the electrodes to be inserted into the contact gap 5.

[0036] Furthermore, the quick-release battery cover structure also includes an insulating layer 6, which is disposed between the electrical contact part 41 and the inner sidewall of the conductive frame 1.

[0037] To prevent the potential for circuit continuity between the power receiving part 41 and the conductive middle frame 1 after the electrodes of the external power supply are connected, an insulating layer 6 is provided between the inner sidewall of the power receiving part 41 and the conductive middle frame 1. This prevents circuit continuity between the power receiving part 41 and the conductive middle frame 1, and also avoids direct connection between the power receiving part 41 and the conductive middle frame 1 during disassembly, thus preventing the formation of an electric field.

[0038] Specifically, the insulating layer 6 can be an anodic oxide film layer, which can be formed locally on the inner sidewall of the conductive frame 1 to achieve insulation between the contact part 41 and the conductive frame 1.

[0039] Specifically, the conductive frame 1 is made of metal, and the insulating battery cover 2 is made of glass. In the complete device state, the outer surface of the conductive frame 1 is usually anodized. The anodized film layer can be removed from the inner wall of the card tray hole or the inner wall of the button hole on the conductive frame 1 to achieve connection with the electrode of the external power supply.

[0040] 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.

[0041] By setting the adhesive step 13, the insulating battery cover 2 is bonded to the conductive frame 1 through the adhesive surface 12 on the adhesive step 13 when no power is applied, resulting in high bonding stability.

[0042] Preferably, the insulating battery cover 2 is rectangular, the conductive layer 4 is right-angled, one side wall of the contact part 41 is attached to the side wall of the insulating layer 6, and the other side wall of the contact part 41 is attached to the outer side wall of the insulating battery cover 2.

[0043] By setting the insulating battery cover 2 to a rectangular shape, the conductive layer 4 to a right angle shape, the conductive layer 4 adapts to the shape of the insulating battery cover 2, and the conductive layer 4 adapts to the adhesive step 13. The two opposite sides of the conductive part 42 are respectively attached to the connecting surface 21 and the electro-adhesive layer 3. The electro-adhesive layer 3 is attached between the conductive part 42 and the adhesive surface 12. It can ensure the bonding stability when no power is applied. When the electrode is connected to the ground part 41 and the conductive frame 1 and is energized, the current can flow through the ground part 41 to the conductive part 42, and then through the conductive part 42 to the second adhesive surface 32 of the electro-adhesive layer 3, thereby forming an electric field on the second adhesive surface 32 and the first adhesive surface 31.

[0044] To further explain, the first adhesive surface 31 is provided to cover the adhesive surface 12, and the end of the conductive part 42 away from the electrical contact part 41 extends to a position flush with the electro-adhesive layer 3.

[0045] By covering the bonding surface 12 with the first adhesive surface 31, the insulating battery cover 2 is bonded to the conductive frame 1 through the bonding surface 12 on the bonding step 13 when no power is applied, resulting in high bonding stability. The end of the conductive part 42 away from the power receiving part 41 extends to a position flush with the electro-adhesive layer 3, ensuring bonding stability while avoiding waste of electro-adhesive.

[0046] To further explain, the conductive layer 4 is a metal conductive film, and the thickness of the conductive layer 4 is 15-25 μm.

[0047] In this embodiment, the thickness of the conductive layer 4 is preferably 20 μm.

[0048] In this embodiment, the conductive layer 4 is an existing metal conductive film. The conductive layer 4 is plated on the insulating battery cover 2. If the thickness of the conductive layer 4 is too thin, the conductivity will be poor. If the thickness of the conductive layer 4 is too thick, it will be easy to fall off. Moreover, because the conductive layer 4 is too thick, the thick conductive layer 4 can be observed from the outside of the conductive frame 1, which affects the appearance and refinement.

[0049] Preferably, the thickness of the electro-adhesive layer 3 is 0.2 to 0.3 mm.

[0050] The thickness of the electro-adhesive layer 3 is within this range, which can ensure the bonding effect. Moreover, the electro-adhesive layer 3 within this thickness range contains a certain amount of cations and anions, which can ensure rapid peeling between the electro-adhesive layer 3 and the conductive middle frame 1 after energizing and forming an electric field on the first adhesive surface 31 and the second adhesive surface 32 of the electro-adhesive layer 3.

[0051] In this embodiment, the thickness of the electro-adhesive layer 3 is preferably 0.3 mm.

[0052] An electronic device includes the aforementioned easy-to-operate quick-release battery cover structure.

[0053] The electronic devices mentioned include mobile phones, tablets, laptops, smartwatches, smart bracelets, and other electronic devices.

[0054] The described electronic device is easy to disassemble and has high disassembly efficiency. It solves the technical problem that the existing battery cover is usually glued to the middle frame inside the middle frame, making it difficult to remove the battery cover from the middle frame, resulting in inconvenient disassembly and low disassembly efficiency.

[0055] 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.
