Technical Field
[0001] This utility model relates to the field of structural design technology for consumer electronics products, and in particular to an easy-to-disassemble tablet computer. Background Technology
[0002] With increasing global emphasis on electronic waste recycling and resource reuse, battery removability and replaceability have become crucial compliance indicators in consumer electronics design. In 2023, the European Union issued Regulation (EU) 2023 / 1542 and its accompanying Guidance on the Application of the Removability and Replaceability Regulations for Portable Batteries and Light Transport Vehicles (LMT), explicitly requiring that batteries in portable devices should be removable and replaceable by end-users or independent professionals without relying on proprietary tools, specialized equipment, heat, or chemical solvents. Specifically, if a battery can be removed from a product using commercially available general-purpose tools such as screwdrivers or pry bars, it is considered "easily removable"; if non-commercially available tools are required, these tools must be provided to independent repair personnel at a reasonable and non-discriminatory price; and proprietary tools are those that are not publicly available or whose patents cannot be licensed under fair, reasonable, and non-discriminatory conditions.
[0003] However, most tablet computers on the market today employ a highly integrated unibody design, requiring specialized tools for disassembly. Forcibly prying them could damage the screen or internal circuitry. While this approach improves overall sealing and structural rigidity, it severely violates the aforementioned regulations' principle of "disassembly without specialized tools" and hinders end-user self-maintenance and the establishment of a third-party repair ecosystem.

[0010] In the easily detachable tablet computer of this utility model, a second assembly gap is reserved between the top of the electric heating element and the inner wall of the upper surface of the detachable end cover. The second assembly gap is used to compensate for the thermal expansion of the material and manufacturing tolerances, and to prevent the electric heating element from being deformed by pressure.
[0011] In the easily detachable tablet computer of this utility model, a third assembly gap is provided between the C-shaped groove and the main body area of the middle plate.

[0021] To provide a clearer understanding of the technical features, objectives, and effects of this utility model, the specific embodiments of this utility model will now be described in detail with reference to the accompanying drawings.
[0022] like Figure 1-7 As shown, this utility model embodiment provides an easy-to-disassemble tablet computer, including a middle plate 10, a detachable end cover 20, an electric heating element 30, and a back cover 40.
[0023] The first end 11 of the middle plate 10 is provided with a fastening screw, which is used to detachably fix the rear cover 40 to the middle plate 10.
[0024] The detachable end cap 20 is sleeved on the outside of the first end 11 of the middle plate 10. The detachable end cap 20, the rear cover 40 and the lower surface of the middle plate 10 together form a battery compartment for accommodating the battery.
[0025] In this embodiment of the invention, the detachable end cap 20 is used to achieve structural encapsulation and modular assembly / disassembly functions. For example... Figures 1-4 As shown, in some embodiments of this utility model, the detachable end cover 20 is located at the edge of one long side of the tablet computer. It is understood that the detachable end cover 20 can also be located at the edge of any other side of the tablet computer. The design of the detachable end cover maintains both a compact product structure and aesthetic industrial design.
[0026] The first end 11 of the middle plate 10 is provided with a groove for accommodating the electric heating element.
[0027] In some embodiments of this utility model, the groove is a U-shaped groove with its opening facing the upper surface 201 of the detachable end cap, and the electric heating element 30 is cylindrical, sheet-like, or prismatic.
[0028] like Figure 4-7 As shown, in some other embodiments of the present invention, the electric heating element 30 is cylindrical, and its diameter is smaller than the thickness of the middle plate 10; the groove is a C-shaped groove 12, and the radial opening 121 of the C-shaped groove 12 is oriented away from the lower surface 202 of the detachable end cover; the inner diameter of the bottom surface 122 of the C-shaped groove matches the diameter of the electric heating element 30, and the width of the radial opening 121 of the C-shaped groove 12 is adapted to the diameter of the electric heating element 30.
[0029] like Figure 4-7 As shown, the radial opening 121 of the C-shaped groove 12 is oriented away from the lower surface 202 of the detachable end cap, which is equivalent to the opening being set upwards. This allows its top end to be limited by the upper surface 201 of the detachable end cap, making installation more convenient and the position more stable. The inner diameter of the bottom surface of the C-shaped groove matches the diameter of the electric heating element 30, effectively limiting its radial movement and improving heat conduction stability and long-term reliability. The radial opening width of the C-shaped groove is adapted to the diameter of the electric heating element, facilitating the installation of the electric heating element 30.
[0030] The detachable end cap 20 is bonded and fixed to the middle plate 10 by double-sided adhesive 50; the bonding area of the double-sided adhesive 50 corresponds to the position of the electric heating element 30; the electric heating element 30 is used to generate heat after being powered on to soften the double-sided adhesive 50, so as to facilitate the removal of the detachable end cap 20.
[0031] In this embodiment of the invention, the bonding area of the double-sided adhesive 50 corresponds to the position of the electric heating element 30. In some specific embodiments, the bonding area includes a first bonding area located on the upper surface 201 of the detachable end cap and a second bonding area located on the lower surface 202 of the detachable end cap. The first and second bonding areas are arranged opposite each other in the thickness direction of the middle plate 10, and the electric heating element 30 is located between the first and second bonding areas. In other embodiments, in addition to the first bonding area on the upper surface 201 of the detachable end cap and the second bonding area on the lower surface 202 of the detachable end cap, a third bonding area is also included on the inner wall of the side of the detachable end cap 20. The third bonding area is directly opposite the end of the first end 11 and is still within the heat conduction range of the electric heating element 30. The electric heating element can also soften the double-sided adhesive in the third bonding area. It is understood that only the first, second, and third bonding areas, or other combinations of these three individual areas, can be provided.
[0032] The first end of the middle plate 10 is also provided with an electric heating element power interface 13, and the electric heating element 30 is electrically connected to the electric heating element power interface 13 through a wire 31.
[0033] The detachable end cap 20 has a clearance hole 21 at the position corresponding to the power interface 13 of the electric heating element. The power interface 13 of the electric heating element extends outward through the clearance hole 21 for connecting to an external power source.
[0034] The easily detachable tablet computer provided by this utility model allows for battery replacement simply by connecting the power interface 13 of the heating element to an external power source. The heating element 30 heats continuously after being powered on, and the double-sided adhesive absorbs the heat, softening at a preset temperature and time. Once the double-sided adhesive 50 has softened, the external power source can be removed, the removable end cover 20 can be pulled off the middle plate 10, exposing the fastening screws. After removing the screws and taking off the back cover 40, the battery can be replaced. The entire removal process requires no external heating source or other special tools. After battery replacement, the removable end cover 20 can be reattached to the middle plate 10 using double-sided adhesive, allowing for repeated disassembly in subsequent applications, thus achieving repeatability and consistency in the disassembly process.
[0035] This utility model's easy-to-disassemble tablet computer integrates a groove, an electric heating element, and a power interface adapted to the electric heating element at the end of the middle plate. By supplying power to the power interface, the electric heating element can be heated, and its heat can be used to soften the double-sided adhesive between the detachable end cover and the middle plate. This enables tool-free and damage-free easy disassembly and assembly of the detachable end cover. Moreover, the disassembly and assembly process is simple, safe, and reversible. End users and third-party repair personnel can operate it themselves, improving the convenience of battery replacement.
[0036] like Figure 7 As shown, in some embodiments of the present invention, the C-shaped groove has a first radial opening 1211 and a second radial opening 1212; The distance from the first radial opening 1211 to the end of the first end 11 is less than the distance from the second radial opening 1212 to the end of the first end 11; The distance from the first radial opening 1211 to the lower surface 202 of the removable end cap is greater than the distance from the second radial opening 1212 to the lower surface 202 of the removable end cap.
[0037] like Figure 7 As shown, the distance from the first radial opening 1211 to the end of the first end 11 is less than the distance from the second radial opening 1212 to the end of the first end 11, and the two radial openings are of different heights, such that the opening of the C-shaped groove 12 is set at an angle, and the two openings form an angled insertion path for the electric heating element 30.
[0038] like Figure 7 As shown in the embodiment of this utility model, the width of the radial opening 121 of the C-shaped groove 12 is greater than the diameter of the electric heating element 30, so that a first assembly gap 60 is formed between the electric heating element 30 and the first radial opening 1211; the first assembly gap 60 is filled with thermally conductive adhesive to enhance the heat conduction efficiency of the electric heating element 30.
[0039] By leaving a gap between the electric heating element 30 and the first radial opening 1211 and filling it with thermally conductive adhesive, the heat transfer efficiency from the middle plate to the double-sided adhesive area can be significantly improved, the softening time can be shortened, and energy consumption can be reduced. Furthermore, the thermally conductive adhesive also serves to limit the position of the electric heating element 30. When the electric heating element 30 is powered on, the thermally conductive adhesive softens as the temperature of the electric heating element 30 increases. After the electric heating element 30 is powered off, its temperature gradually decreases, and the thermally conductive adhesive gradually regains its tackiness, thus re-fixing the electric heating element 30 within the C-shaped groove.
[0040] like Figure 7 As shown in the embodiment of this utility model, a limiting boss 14 is formed between the second radial opening 1212 and the bottom of the C-shaped groove 12; The vertical distance from the inner wall of the upper surface 201 of the detachable end cap to the limiting boss 14 is less than the diameter of the electric heating element 30, so as to prevent the electric heating element 30 from coming out of the second radial opening 1212.
[0041] The limiting boss 14 forms a mechanical stop with the inner wall of the upper surface 201 of the detachable end cover, which effectively prevents the electric heating element 30 from sliding out of the second radial opening during vibration or thermal expansion, ensuring that it is stably located in the C-groove for a long time and improving the reliability of the product.
[0042] like Figure 7 As shown in the present invention embodiment, a second assembly gap 61 is reserved between the top end of the electric heating element 30 and the inner wall of the upper surface 201 of the detachable end cover. The second assembly gap 61 is used to compensate for the thermal expansion of the material and manufacturing tolerances, and to prevent the electric heating element 30 from being deformed by pressure.
[0043] By reserving a second assembly gap 61 at the top of the electric heating element 30, the axial displacement and manufacturing tolerance caused by the thermal expansion of the electric heating element 30 can be absorbed, avoiding deformation or stress cracking caused by it pressing against the inner wall of the detachable end cover 20, thus extending its service life.
[0044] like Figures 3-6 As shown in the embodiment of this utility model, a third assembly gap 62 is provided between the C-shaped groove 12 and the main body area of the middle plate 10.
[0045] like Figures 3-6 As shown, in some specific embodiments of this utility model, the third assembly gap 62 is a through hole provided along the length direction of the C-shaped groove 12. The third assembly gap 62 further improves the assembly convenience of the electric heating element 30, and at the same time, isolates the heat from the middle plate body, avoiding the influence of heat on other components on the middle plate body.
[0046] In some embodiments of this utility model, the detachable end cap 20 is made of PC / ABS alloy injection molding, and its inner surface is provided with positioning buckles, which cooperate with the slots on the outer periphery of the first end 11 of the middle plate 10 to achieve pre-positioning and then bonding and fixing.
[0047] In some embodiments of this invention, the double-sided adhesive is a high-temperature resistant acrylic foam adhesive, which softens after being heated at 80°C for 5 minutes. The electric heating element 30 is a PTC ceramic heating plate or a nickel-chromium alloy resistance heating element, with an operating temperature range of 60°C–120°C. Heating it for about 5 minutes softens the acrylic double-sided adhesive without damaging surrounding structural components.
[0048] In some embodiments of this utility model, the electric heating element 30 has a diameter of 2.6mm and is powered by a DC 5V low-voltage power supply. The power interface 13 of the electric heating element is a spring-loaded charging interface located on the side of the product. When disassembling the product, the electric heating element 30 is powered by the dedicated power cord provided with the product in the off state. The power supply lasts for 5 minutes each time and then automatically cuts off. At this time, the double-sided adhesive has been fully softened and the detachable end cover 20 can be directly removed.
[0049] The embodiments of the present invention have been described above with reference to the accompanying drawings. However, the present invention is not limited to the specific embodiments described above. The specific embodiments described above are merely illustrative and not restrictive. Those skilled in the art can make many modifications under the guidance of the present invention without departing from the spirit and scope of the claims. All of these modifications are within the protection scope of the present invention.
