Specifically, in one embodiment, the battery protection film 100 is substantially square, and one edge thereof is arc-shaped. In order to better explain the adhesive film 10, the adhesive film 10 is divided into a first region a and a second region B. The first area A is a square area, and the second area B is an arc area. The adhesive film 10 and the tear film 20 jointly form the battery protection film 100, the tear film 20 is disposed in the adhesive film 10, a part of the tear film 20 is located in the first area a, and a part of the tear film 20 is located in the second area B.
Referring to fig. 1, the adhesive film 10 has a substantially square outline, and the right side of the adhesive film 10 has a substantially arc shape. The first adhesive surface 11 of the adhesive film 10 is provided with a first adhesive area 111 and a first adhesive-free area 112, the first adhesive area 111 is mainly disposed on the first area a, and the other areas except the first adhesive area 111 are the first adhesive-free area 112. In one embodiment, a plurality of the first adhesive zones 111 are disposed on the first area a, specifically, three first adhesive zones 111 are disposed on the first area a, the first adhesive zones 111 are substantially in the shape of a long strip and an L, and the three first adhesive zones 111 and the first non-adhesive zones 112 are disposed at intervals.
The first adhesive region 111 and the first non-adhesive region 112 are disposed according to the positions of the components in the battery compartment. It is understood that in other embodiments, the number and number of the first adhesive zones 111 can be set according to specific situations. For example, four first adhesive zones 111 may be disposed in parallel on the first area a, and the first adhesive zones 111 are in a wave shape. The first adhesive-free region 112 is coated with ink so that it cannot be bonded in place.
The first adhesive region 111 is not disposed on the second region B.
Referring to fig. 2, the adhesive film 10 is provided with a second adhesive area 121 and a second adhesive-free area 122 on the second adhesive surface 12, and the second adhesive-free area 122 is located on one side of the second adhesive area 121. The adhesive strength of the second adhesive zone 121 is less than that of the first adhesive zone 111, so that when the battery is disassembled, the adhesive film 10 is left in the battery compartment, and the battery can be directly taken out.
Specifically, the second adhesive region 121 is disposed on the whole area of the first region a, and a part of the second adhesive region 121 is also disposed on the second region B. The second non-adhesive region 122 is disposed at the edge of the second region B, and occupies a smaller area. When the battery is disassembled, the second glue-free area 122 can be used as a first disassembling position for disassembling the battery.
The second adhesive region 121 can be further divided into a first adhesive portion 1211 and a second adhesive portion 1212. The first adhesive portion 1211 is disposed on a side of the first area a away from the second area B, and is disposed on a side of the second area B close to the first area a, and the second adhesive portion 1212 is disposed at other positions. The adhesive strength of the first adhesive portion 1211 is greater than the adhesive strength of the second adhesive portion 1212.
Further, the first adhesive portion 1211 is substantially in a shape of a strip, and the second adhesive portion 1212 is substantially in a shape of a dot. The spot-shaped glue is divided into three types, the diameter of the first spot-shaped glue is 0.7mm, the distance between two adjacent spot-shaped glues is 2mm, and the first spot-shaped glue is arranged at the approximate center of the first area A. The diameter of the second medium point glue is 1mm, the distance between two adjacent point glues is 10mm, and the second point glue is arranged on the first area A and positioned on two sides of the first medium point glue. The third middle point-shaped glue is 1.2mm in diameter, the distance between two adjacent point-shaped glues is 2mm, and the third middle point-shaped glue is arranged on the second area B, is positioned on two sides of the first glue part 1211, and is adjacent to the second point-shaped glue.

Referring to fig. 1 again, the tear film 20 includes a handle 21 and a connecting portion 22, and the handle 21 is connected to the connecting portion 22. The handle 21 is substantially arc-shaped, and a first slit 23 is formed between the handle 21 and the adhesive film 10, so that the handle 21 can be better handled when the battery is disassembled. The connecting portion 22 is substantially square, a second slit 24 is formed between the end portion of the connecting portion 22 far away from the handle 21 and the adhesive film 10, the tear line 30 is arranged between the two side edges of the connecting portion 22 and the adhesive film 10, and after the handle 21 is pulled, the handle 21 can drive the connecting portion 22 along the tear line 30, so that the connecting portion 22 is separated from the adhesive film 10.
It is understood that in other embodiments, the shape of the handle 21 and the connecting portion 22 is not limited thereto, as in another embodiment, the handle 21 may be square and the connecting portion 22 may be round or other shapes.
The tearing film 20 is not provided with any adhesive area on the first adhesive surface 11, and the handle 21 and the connecting portion 22 are both adhesive-free areas, that is, the tearing film 20 cannot be adhered to the battery compartment.
Referring to fig. 2 again, the connecting portion 22 of the tear film 20 is provided with a third adhesive region 221 on the second adhesive surface 12, and the third adhesive region 221 is adhered to the battery. The adhesion degree of the third adhesive section 221 is substantially the same as the adhesion degree of the first adhesive section 1211, but the adhesion area of the third adhesive section 221 is concentrated, so that the connection section 22 can still fix the battery and drive the battery to move.
The handle 21 is provided with adhesive areas on both the first adhesive surface 11 and the second adhesive surface 12, so that the handle 21 can be used as a second disassembling position for disassembling the battery.
Referring to fig. 1 and 2 again, the tear line 30 includes a plurality of thin connecting lines 31, two ends of the connecting lines 31 are respectively connected to the adhesive film 10 and the connecting portions 22 on the tear film 20, and the connecting lines 31 are obliquely disposed between the adhesive film 10 and the connecting portions 22. Further, when the connecting line 31 faces the handle 21, an included angle between the connecting line 31 and the edge of the connecting portion 22 is an acute angle.
It will be appreciated that in other embodiments, the connecting line 31 is oriented towards the handle 21 at an obtuse angle to the edge of the connecting portion 22, i.e. the line 31 is inclined in a different direction. Through adopting the inclined connecting line 31, the tearing film 20 is disconnected along the direction of the tearing line 30 in the tearing process, so that the tearing film 20 can be better separated from the bonding film 10, and the situation that the bonding film 10 is torn in the tearing process is avoided.
Referring to fig. 1 and fig. 2 again, when the battery is fixed in the battery compartment through the battery protection film 100, the battery is disposed on the second bonding surface 12, and the second bonding surface 12 may cover the battery beyond the edge of the battery, that is, the edge of the first region a may cover a portion of the battery. The second adhesive area 121 and the third adhesive area 221 are adhered to the battery, and after the battery is fixed, the first adhesive surface 11 of the battery protective film 100 is adhered to the inside of the battery through the first adhesive area 111, so that the battery is fixed in the battery compartment.
When the battery needs to be disassembled, the handle 21 is pulled, the handle 21 drives the connecting portion 22 to move along the direction of the tearing line 30, the tearing line 30 is disconnected, and the connecting portion 22 drives the battery to be separated from the adhesive film 10. Since the bonding strength of the second adhesive portion 1212 is smaller than that of the third adhesive section 221, and the bonding area of the third adhesive section 221 is concentrated, the first adhesive portion 1211 located in the second region B cannot fix the battery. Finally, the battery is removed from the battery compartment by tearing the battery from the first adhesive 1211 located at the end of the first region a remote from the second region B.
Second embodiment
Referring to fig. 3, a second embodiment provides a battery module 200, wherein the battery module 200 includes a battery 40 and a battery protection film 100 as in the first embodiment, and the battery protection film 100 is adhered to the battery 40 to fix the battery 40. The battery 40 is a lithium battery and can be applied to a mobile communication tool, such as a mobile phone. It is understood that in other embodiments, the battery 40 may be a battery of other materials, and the applied scenario may be replaced.
Third embodiment
Referring to fig. 4, a third embodiment provides a mobile device 300, wherein the mobile device 300 includes a battery compartment 50, a battery, such as the battery 40 of the second embodiment, and a battery protection film 100 of the first embodiment. The battery protection film 100 is bonded to the battery, and the battery is bonded to the battery compartment 50 through the battery protection film 100. So that the battery can supply power to the mobile device 300, specifically, the mobile device 300 can be a mobile phone, and the battery is disposed in the battery compartment 50 to supply power to the mobile phone. It is understood that in other embodiments, the mobile device 300 may be replaced by a camera, a notebook computer, a tablet computer, a mobile charger, etc.
To sum up, the battery protection film 100 that this application provided can be bonding battery compartment and battery, need not to use double faced adhesive tape and coating film to be fixed in the battery compartment with the battery jointly, can effectual save material cost and processing cost. Meanwhile, the adhesive film 10 and the tear film 20 in the battery protection film 100 are connected by the inclined tear line 30, so that the tear film 20 can be ensured to move along the tear line in the process of pulling the tear film 20, and the adhesive film 10 can be effectively prevented from being broken in the tearing process.
