[0023] This utility model proposes a double-sided adhesive structure 100.

[0024] Please see Figure 1 In one embodiment of the present invention, the double-sided adhesive structure 100 includes a double-sided adhesive 1 and an anti-adhesive layer 2. The double-sided adhesive 1 has an extension 11. The anti-adhesive layer 2 is disposed on two opposing surfaces of the extension 11 and is connected to the double-sided adhesive 1.

[0025] In this embodiment, the double-sided adhesive structure 100 can be applied to components in electronic products to facilitate the fixation of the double-sided adhesive and improve product reliability. Combined with... Figure 1 It should be noted that the material of the double-sided adhesive includes, but is not limited to, plastic film-based double-sided adhesive, non-woven fabric-based double-sided adhesive, PVC-based double-sided adhesive, and other tough materials, and is not limited here. The material of the anti-adhesive layer 2 includes, but is not limited to, PET (polyethylene terephthalate), Mylar, etc., and is not limited here. Specifically, the double-sided design of the anti-adhesive layer 2 is adhesive-free, so as to bond with the double-sided adhesive 1. It should be noted that the extension 11 can be understood as a part of the double-sided adhesive, that is, the part of the double-sided adhesive 1 that extends to form the anti-adhesive layer 2 is the extension 11. The position of the extension 11 on the double-sided adhesive 1 is not limited; it can be located in the middle of the double-sided adhesive 1 or at the end of the double-sided adhesive 1. In one embodiment, the double-sided adhesive 1 is T-shaped, the extension 11 is located in the middle of the double-sided adhesive 1, and the anti-adhesive layer 2 is located on the two opposite surfaces of the extension 11. The part of the double-sided adhesive 1 without the anti-adhesive layer 2 is bonded to the component to be bonded. In another embodiment, the double-sided adhesive 1 is arranged in a 1-shape, with an extension 11 disposed at one end of the double-sided adhesive 1, and an anti-adhesive layer 2 disposed on the two opposing surfaces of the extension 11. The portion of the double-sided adhesive 1 without the anti-adhesive layer 2 is bonded to the component to be bonded.

[0026] Understandably, when manufacturing the double-sided adhesive structure 100 provided by this utility model, on the positioning jig base, using the four positioning posts on the positioning jig base as a reference, a release protective film, a first release film 3, and an anti-adhesion layer 2 are placed sequentially; secondly, an anti-adhesion layer 2 is cut off at the center position of the positioning jig using a first die, and then, using the four positioning posts on the positioning jig base as a reference, the double-sided adhesive, the tissue box protective film, and another anti-adhesion layer 2 are placed into the jig; thirdly, another anti-adhesion layer 2 is cut off at the center position of the positioning jig using a second die; fourthly, the tissue box process is then used. Step 1: Remove the protective film from the tissue box; Step 2: Based on Step 4, cover with a protective release film to protect the double-sided adhesive; Step 3: Cover with a protective release film; Step 4: Cut out the shape of one anti-adhesive layer 2, double-sided adhesive, another anti-adhesive layer 2, and protective release film using a third die; Step 5: Cut out the shape of the first release film 3 using a fourth die; Step 6: Take out the cut sample and tear off the protective release film; Step 7: Transfer the sample from Step 9 to the second release film 4. The final product is the double-sided adhesive structure 100 proposed in this utility model.

[0027] The technical solution of this utility model involves an extension 11 on the double-sided adhesive 1, with anti-adhesive layers 2 provided on opposite sides of the extension 11. The anti-adhesive layers 2 are non-adhesive yet tightly connected to the double-sided adhesive 1. The anti-adhesive layers 2 provide an easy-to-use grip, allowing the user to easily separate the double-sided adhesive from the attached item. When disassembling the battery pack 200, the user simply pinches the location of the anti-adhesive layers 2 with their fingers to detach the double-sided adhesive from the battery pack 200, achieving quick removal or battery replacement. The presence of the anti-adhesive layers 2 allows the user to quickly remove the battery from the battery compartment. Compared to traditional double-sided adhesive fixing methods, this structure significantly reduces the time and effort required to disassemble the battery pack 200, improving disassembly efficiency.

[0028] In one embodiment of the present invention, the double-sided adhesive 1 further includes a main body 12, and an extension 11 is connected to one end of the main body 12 and is provided with rounded corners.

[0029] In this embodiment, it should be noted that the main body 12 is the primary adhesive portion of the double-sided tape 1, providing sufficient adhesion to ensure stable adhesion of the object. The extension 11, connected to one end of the main body 12, is rounded at one end. This rounded corner design allows the double-sided tape 1 to better adhere to the object surface during adhesion, reducing stress concentration at the edges and thus lowering the risk of lifting due to sharp edges. Simultaneously, the rounded corner extension 11 is also safer during use, avoiding potential injury to the user from sharp edges and improving the safety of using the double-sided tape.

[0030] In one embodiment of the present invention, the double-sided adhesive 1 has a notch 13 and the extension 11 includes two first film segments 111. The two first film segments 111 and the main body 12 surround to form the notch 13. The two first film segments 111 are respectively connected to the opposite ends of the main body 12, and the end of each first film segment 111 near the main body 12 is rounded.

[0031] In this embodiment, combined with Figure 3 The two first film segments 111 of the main body 12 and the extension 11 enclose and form a notch 13. Specifically, the main body 12, as the main part, provides basic adhesive function and structural support for the double-sided adhesive 1. The two first film segments 111 are respectively connected to the opposite ends of the main body 12. This arrangement allows the double-sided adhesive 1 to better adapt to the surfaces of objects with different shapes during use, increasing the flexibility and applicability of the adhesive. At the same time, in order to prevent tearing of the double-sided adhesive 1, the end of each first film segment 111 near the inner wall of the notch 13 is rounded. This design not only helps to reduce stress concentration and improve the structural stability of the double-sided adhesive 1 under stress, but also avoids damage to the object being adhered to by sharp edges during the adhesive process, enhancing the safety and reliability of the product. In addition, the rounded corner design also facilitates the demolding and molding of the double-sided adhesive during the production process, improving production efficiency and reducing production costs.

[0032] In one embodiment of the present invention, each anti-adhesion layer 2 is connected to the first membrane segment 111, and the shape of each anti-adhesion layer 2 is adapted to the shape of the first membrane segment 111.

[0033] In this embodiment, combined with Figure 1 and Figure 3 By employing a design where each anti-adhesive layer 2 is individually connected to the first film segment 111, and the shape of each anti-adhesive layer 2 is adapted to the shape of the first film segment 111, the problem of weak adhesion and easy detachment of the anti-adhesive layer 2 from the film segment during use of the double-sided adhesive 1 can be solved. Specifically, each anti-adhesive layer 2 is individually connected to the first film segment 111. This connection method ensures a tight bond between the anti-adhesive layer 2 and the first film segment 111, allowing the anti-adhesive layer 2 to stably pull the first film segment 111 apart when the double-sided adhesive 1 is torn off, preventing separation between the anti-adhesive layer 2 and the first film segment 111. Simultaneously, the shape of each anti-adhesive layer 2 is adapted to the shape of the first film segment 111, allowing the anti-adhesive layer 2 to better conform to the shape of the first film segment 111, further enhancing the connection strength and stability between the two. This design not only improves the reliability and stability of the double-sided adhesive during use but also makes the tearing process smoother and more convenient, enhancing the user experience.

[0034] In one embodiment of this utility model, the width of each anti-adhesive layer 2 is greater than the width of the first film segment 111.

[0035] In this embodiment, to avoid uneven stress, the width of each release layer 2 is greater than the width of the first film segment 111. This gives the release layer 2 a larger stress-bearing area during the tearing process, making it easier and more stable to tear, preventing incomplete tearing. Simultaneously, this structural design also improves the overall strength and reliability of the double-sided adhesive, avoiding problems such as incomplete tearing or accidental tearing caused by an excessively narrow release layer 2. This makes the double-sided adhesive more convenient and quick to use, improving the user experience.

[0036] In one embodiment of the present invention, the double-sided adhesive also has a main body 12, and the anti-adhesive layer 2 includes two tear-off parts, which are respectively disposed on two opposing surfaces of the extension 11, and the ends of the two tear-off parts near the main body 12 are rounded.

[0037] In this embodiment, combined with Figure 1 By employing two tear-off sections located on opposite sides of the inner wall of the notch 13, with rounded corners at the ends of the two tear-off sections near the notch 13, the problem of uneven tearing and difficulty in tearing the anti-adhesive layer 2 during use can be solved. Specifically, the two tear-off sections ensure more even force distribution when tearing the anti-adhesive layer 2, avoiding uneven tearing caused by uneven force distribution. The rounded corner design at the ends near the notch 13 further reduces tearing resistance, making the anti-adhesive layer 2 easier to tear and reducing damage to the anti-adhesive layer 2 itself during tearing, thus increasing its service life. This design not only improves the ease of use of the anti-adhesive layer 2 but also enhances its structural stability, making the anti-adhesive layer 2 more reliable and efficient in practical applications.

[0038] In one embodiment of the present invention, the double-sided adhesive structure 100 further includes a first release film 3 and a second release film 4. The first release film 3 is disposed on the outer side of one side of the double-sided adhesive 1 and is connected to the anti-adhesive layer 2; the second release film 4 is disposed on the outer side of the other side of the double-sided adhesive 1 and is connected to the anti-adhesive layer 2.

[0039] In this embodiment, combined with Figure 2 and Figure 3To prevent the adhesive portion of the double-sided adhesive 1 from being exposed to dust, debris, or other external contaminants when not in use, a first release film 3 and a second release film 4 are provided on both sides of the double-sided adhesive 1. These release films 3 and 4 prevent the adhesiveness of the double-sided adhesive from decreasing. It is understood that the material of the first release film 3 includes, but is not limited to, PE (polyethylene), PP (polypropylene), and PET (polyethylene terephthalate), etc. Here, non-adhesive PET (polyethylene terephthalate) is used. The material of the second release film 4 is the same as that of the first release film 3, and will not be elaborated further here. The connection between the first release film 3, the second release film 4, and the anti-adhesive layer 2 is electrostatic adsorption, and all three are designed to be adhesive-free. This arrangement, by using the first release film 3 and the second release film 4, allows users to easily peel off the double-sided adhesive 1 and apply it to the desired location when needed, without affecting the usability due to damaged adhesiveness, thus improving the convenience and reliability of the double-sided adhesive.

[0040] In one embodiment of the present invention, the length of the first release film 3 is greater than the length of the anti-adhesive layer 2 connected to the first release film 3.

[0041] In this embodiment, to ensure easy removal of the first release film 3 during use, the length of the first release film 3 is set to be relatively long, combined with... Figure 1 The first release film 3 covers the double-sided adhesive and the anti-adhesive layer 2, and is longer than the end of the double-sided adhesive where the anti-adhesive layer 2 is located. Specifically, the length of the first release film 3 is approximately 1mm longer than the length of the anti-adhesive layer 2 to which it is connected. This value can be set as needed and is not limited here. Because the first release film 3 is longer, operators can more easily find and grasp its edge during use, making it easy to peel off from the connection point or other areas requiring separation. This design makes the operation process more convenient and efficient, reducing the risks of disassembly difficulties due to insufficient release film length, the need for additional tools, or potential product damage. This improves the user experience and production efficiency, and reduces production costs.

[0042] In one embodiment of this utility model, the size of the first release film 3 is smaller than the size of the second release film 4.

[0043] In this embodiment, to facilitate the use of the first release film 3, its size is smaller than that of the second release film 4. This solves problems such as edge adhesive overflow and poor adhesion caused by improper size matching during use. Specifically, the smaller size of the first release film 3 allows it to precisely cover the core area when in contact with one side of the double-sided adhesive 1, avoiding situations where excess edges cannot adhere tightly due to excessive size. The larger size of the second release film 4 provides broader protection and auxiliary adhesion for the other side of the double-sided adhesive 1, building upon the first release film 3. Its edges can better adhere to surrounding components or structures, preventing the intrusion of external impurities and dust. It also disperses stress to a certain extent, preventing damage to the release film due to excessive local stress.

[0044] This utility model also proposes a battery pack 200, which includes a base 220, a battery 210, and a double-sided adhesive structure 100 as described above. The specific structure of the double-sided adhesive structure 100 is as described in the above embodiments. Since the battery pack 200 adopts all the technical solutions of all the above embodiments, it has at least all the beneficial effects brought about by the technical solutions of the above embodiments, which will not be described in detail here. One end of the double-sided adhesive structure 100 is bonded to the battery, and the other end is bonded to the base 220. The anti-adhesive layer 2 of the double-sided adhesive structure 100 is configured to be pulled to separate the battery from the base 220.

[0045] In this embodiment, combined with Figure 4 It should be noted that, firstly, two double-sided adhesive structures 100 are attached to the base 220, with the anti-adhesive layer 2 located on the side of the double-sided adhesive facing away from the base 220; secondly, the battery is installed and secured with pressure. When disassembling the battery pack 200, the user only needs to pinch the location of the anti-adhesive layer 2 with their fingers to separate the double-sided adhesive from the battery pack 200, achieving the function of quickly removing or replacing the battery. The presence of the anti-adhesive layer 2 allows the user to quickly remove the battery from the battery compartment. Compared with the traditional double-sided adhesive fixing method, this structure greatly reduces the time and effort required to disassemble the battery pack 200, improving disassembly efficiency.

[0046] The above description is merely an exemplary embodiment of the present utility model and does not limit the patent scope of the present utility model.
