The battery fixing removable adhesive according to an embodiment of the present utility model is described below with reference to fig. 1 to 3.

As shown in fig. 1-3, the battery securing removable adhesive includes an adhesive layer 100, a tear-away portion 210, a fold-over portion 220, and a traction portion 230. Specifically, the adhesive layer 100 is laid along the extending direction of the battery structure, a tearing portion 210 is provided at one end of the adhesive layer 100, the tearing portion 210 extends to the outside of the battery and the mounting surface, and is used for providing a tearing position, and a user pulls the adhesive layer 100 between the battery and the mounting surface through the tearing portion 210, so that the adhesive layer 100 is stretched and deformed and separated from the battery and the mounting surface, i.e. the adhesive layer 100 is separated from the bottom surface of the battery and the surface of the mounting surface. The other end of the adhesive layer 100 is provided with a turnover part 220, the turnover part 220 turns over towards the surface direction of the battery, and the turnover part 220 after turning over is positioned between the adhesive layer 100 and the surface of the battery. A traction portion 230 is provided between the tear portion 210 and the turnover portion 220, and the traction portion 230 is laid along the extending direction of the adhesive layer 100. When the user pulls the pulling part 210, the pulling part 230 and the adhesive layer 100 are pulled at the same time, and the folding part 220 can be folded between the mounting surface and the adhesive layer 100 when the pulling part 230 is pulled, so that the tail ends of the adhesive layer 100 are separated in advance, and the tail end pasting force of the adhesive layer 100 is reduced. The end of the adhesive layer 100 is the end near the inside of the bottom surface of the battery, the head end is the end far away from the inside of the bottom surface of the battery, the tearing part 210 is positioned at the head end, and the turnover part 220 is positioned at the tail end.

The traction portion 230 is laid in a wave shape along the extending direction of the adhesive layer 100, and specifically, the laying shape of the traction portion 230 is identical to the image of the sine or cosine function. The two traction portions 230 are symmetrically distributed along a central line of the extending direction of the adhesive layer 100.

The adhesive layer 100 has the same effect as the prior battery back adhesive, and the two surfaces of the adhesive layer 100 are mainly adhered to the surface and the mounting surface of the battery, so that the battery is fixed on the mounting surface, and the effect of adhesion and fixation is achieved. When the tearing portion 210 pulls the adhesive layer 100 and the traction portion 230, the peak and the trough of the traction portion 230 gradually draw close to the middle of the traction portion 230 in the straightening process, and in this process, the adhesive layer 100 receives a pulling force directed to the body of the traction portion 230, so that the adhesive layers 100 are shrunk toward the middle, and the adhesive layer 100 is more easily separated from the battery and the mounting surface. And the traction part 230 can also prevent the difficult removal caused by the breakage and shrinkage of the adhesive layer 100 in the bottom surface of the battery in the pulling process, and the traction part 230 and the adhesive layer 100 are pulled simultaneously, so that when the adhesive layer 100 is broken, the adhesive layer 100 and the traction part 230 keep adhesion, the shrinkage acting force generated by the breakage of the adhesive layer 100 can be reduced, and even if the adhesive layer 100 is broken, the traction part 230 can still be pulled by the tearing part 210, so that the traction part 230 drives the adhesive layer 100 to be separated from the battery and the mounting surface, the tearing difficulty is reduced, and the adhesive is more convenient to remove.

In some embodiments of the present utility model, as shown in fig. 1 and 2, the traction portion 230 is a nylon thread, one end of the traction portion 230 is adhered to the tear portion 210, the other end is adhered to the turnover portion 220, and the surface of the turnover portion 220 is adhered to the surface of the adhesive layer 100. Specifically, when the traction portion 230 is pulled, the turnover portion 220 is stretched by the traction portion 230 and turned between the mounting surface and the adhesive layer 100, so that the end of the adhesive layer 100 is separated from the bottom surface of the battery, the end viscosity of the adhesive layer 100 is reduced, and the adhesive is convenient to remove.

In some embodiments of the present utility model, as shown in fig. 1 and 3, the spacing between the peaks and valleys of the traction portion 230 is 3.0mm-5.0mm. Specifically, the distance between the peaks and the valleys of the traction portion 230 determines the degree of narrowing of both sides of the adhesive layer 100 during the straightening process of the traction portion 230, when the distance is too small, the shrinkage effect of both sides of the adhesive layer 100 is not obvious, the effect of reducing the viscosity of the adhesive cannot be achieved, and when the distance is too large, the arrangement distance between the traction portions 230 on the adhesive layer 100 is increased, which is inconvenient for the adhesion of the bottom surface of the small-sized battery.

In some embodiments of the present utility model, as shown in FIG. 2, the adhesive layer 100 is a pop-top adhesive, and the thickness of the adhesive layer 100 is 0.1mm-0.3mm. Specifically, the easy-to-pull adhesive has the effects of water resistance, strong viscosity, good anti-vibration effect and the like, can remove the adhesive without residual adhesive during maintenance or removal, and is widely applied to the fixing range of electronic elements. The easy-pull adhesive is a technical solution well known to those skilled in the art, and will not be described in detail in this embodiment.

In some embodiments of the present utility model, as shown in fig. 2, the thickness of the adhesive layer 100 is greater than the thickness of the traction portion 230, and the traction portion 230 is embedded in the middle layer of the adhesive layer 100. Specifically, in order to prevent the adhesive layer 100 from being separated from the traction portion 230, the traction portion 230 is formed together with the adhesive layer 100, and the traction portion 230 is embedded in the adhesive layer 100, so that the adhesion is prevented from being affected by the traction portion 230 protruding from both surfaces of the adhesive layer 100.

In some embodiments of the present utility model, as shown in fig. 1 and 3, when the tearing portion 210 is pulled away from the adhesive layer 100, the pulling portion 230 has a tendency to straighten, and both sides of the adhesive layer 100 have a tendency to narrow toward the pulling portion 230.

Specifically, during the stretching process of the traction portion 230, the traction portion 230 can shrink the two sides of the adhesive layer 100 toward the middle, so as to reduce the adhesion degree of the adhesive layer 100, and remove more conveniently. When the adhesive layer 100 breaks, the adhesive layer 100 and the traction portion 230 are adhered, so that the breaking shrinkage degree of the adhesive layer 100 can be reduced, and after the adhesive layer 100 breaks, the tearing portion 210 is still connected together with the traction portion 230, and the broken adhesive layer 100 is gradually pulled out by pulling the traction portion 230, so that the difficulty is reduced.

In some embodiments of the present utility model, as shown in fig. 1 and 3, the traction part 230 is provided with at least 2N pieces, N being a positive integer. In order to make the two sides of the adhesive layer 100 uniformly stressed and contracted, the traction portions 230 are symmetrically distributed, so as to ensure that the number of the traction portions 230 distributed on the two sides of the adhesive layer 100 is consistent. The specific number of traction portions 230 is adjusted according to the area of the battery and the mounting surface. When the battery of the tablet computer or the notebook computer is fixed, 4 and 6 traction parts 230 may be provided. When the battery of the smart phone is fixed, the traction part 230 may be provided with 2 bars.

In some embodiments of the present utility model, as shown in fig. 3, the adhesive layer 100 includes a main body tearing area 110 and a side tearing area 120, a traction portion 230 of the side tearing area 120 is connected with a traction portion 230 of the main body tearing area 110, and the main body tearing area 110 and the side tearing area 120 are integrally formed.

Specifically, the structure of the adhesive layer 100 is also different according to different types of batteries, and when the battery is in a regular rectangular structure, the adhesive layer 100 is provided with only the main body tearing area 110. When the battery is L-shaped, the adhesive layer 100 is simultaneously provided with a main body tearing area 110 and a side tearing area 120, the side tearing area 120 is stuck on one side of the small area of the battery, and the main body tearing area 110 is stuck on one side of the large area of the battery. In the tearing process, the traction part 230 of the main body tearing area 110 can drive the traction part 230 of the side tearing area 120 to stretch, and the L-shaped structure battery is more convenient to remove.

In some embodiments of the present utility model, both surfaces of the adhesive layer 100 are covered with protective films (not shown in the drawings), respectively, for preventing dust from adhering to the adhering surface 211 of the adhesive layer 100. Specifically, when the adhesive is not in use, the two surfaces of the adhesive layer 100 need to be covered by the protective film, so that dust is prevented from entering the adhesive in the unused state, and the adhesive performance of the adhesive is prevented from being affected.

In some embodiments of the present utility model, as shown in fig. 1-3, the side of the tear portion 210 near the surface of the battery is provided with an adhesive surface 211, and the adhesive surface 211 is used to fix the position of the tear portion 210.

Specifically, the adhesive surface 211 of the tear portion 210 can make the tear portion 210 adhere to the surface of the battery, limit the tear portion 210, and separate the tear portion 210 from the surface of the battery during the removal process, so as to facilitate the assembly of the electronic component.
