The second insulating film 5 is disposed on the second surface 12, and a portion of the second insulating film 5 extends to the device module 2 and is bonded to the encapsulation layer 3. Thus, the body module 1 and the device module 2, which are originally independent of each other, can be integrally formed by the first insulating film 4 and the second insulating film 5. The first insulating film 4 and the second insulating film 5 may be film structures constructed of an insulating material (e.g., PE), which may have adhesiveness for encapsulating the body module 1.

As shown in fig. 1 to 10, a battery 100 of an electronic device 200 according to an embodiment of the present invention includes: the module comprises a body module 1, a device module 2, a wrapping layer 3, a first insulating film 4, a second insulating film 5 and a tensile adhesive 6.

The device module 2 is connected with the body module 1, and may include electrical elements 22 for testing the performance of the battery 100. The wrapping layer 3 may be used to wrap the device module 2 for protecting the device module 2.
As shown in fig. 1-2 and 5-8, the first insulating film 4 is disposed on the first surface 11, and a portion of the first insulating film 4 extends to the device module 2 and is adhered to the encapsulation 3, and the second insulating film 5 is disposed on the second surface 12, and a portion of the second insulating film 5 extends to the device module 2 and is adhered to the encapsulation 3. Thus, the body module 1 and the device module 2, which are originally independent of each other, can be integrally formed by the first insulating film 4 and the second insulating film 5. The first insulating film 4 and the second insulating film 5 may be film structures constructed of an insulating material (e.g., PE), which may have adhesiveness for encapsulating the body module 1.
As shown in fig. 2, the pop-top tape 6 may be an auxiliary member for detaching the battery 100, and may include an adhesive portion 61, a non-adhesive region 62, and a grip portion 63. The viscosity of the bonding part 61 is greater than that of the handle part 63, the viscosity of the handle part 63 is greater than that of the non-adhesive area 62, and the viscosity of the bonding part 61 is much greater than that of the non-adhesive area 62. Bonding portion 61 is located the one end of easy-pulling glue 6 and bonds with second surface 12, and handle portion 63 is located the other end of easy-pulling glue 6, and handle portion 63 walks around device module 2 and the overlap joint of first insulating film 4, and handle portion 63 is located the one side of keeping away from device module 2 of first insulating film 4, and glueless district 62 is located between bonding portion 61 and the handle portion 63 and glueless district 62 and the laminating of parcel layer 3.
Note that, in the non-adhesive region 62, at least one of the surface of the easy-open adhesive 6 facing the device module 2 and the surface thereof facing away from the device module 2 is a less adhesive or non-adhesive surface.
The easy-pulling glue 6 belongs to a bonding material and comprises a TPU film and rubber type glue, at least one side of the surfaces of the upper side and the lower side of the TPU film can be provided with the glue (such as the rubber type glue), and the rubber type glue comprises the following raw materials in parts by weight: 3050 part of thermoplastic rubber, 30-50 parts of C5 petroleum resin, 20-40 parts of terpene resin, 1-10 parts of plasticizer, 0.1-2 parts of pigment, 1-5 parts of polyisobutylene and 100 parts of toluene ion-exchange resin; the thickness of the TPU film is 30-100 microns, the thickness of the rubber type glue is 20-50 microns, and the rubber type glue is attached to the TPU film in a coating mode.
When the battery 100 is detached from the housing 7 of the electronic device 200, the handle portion 63 of the easy-open adhesive 6 can be pulled to slowly pry up the body module 1 and the device module 2, and the easy-open adhesive 6 can drive the battery 100 to move due to the adhesion of the adhesion portion 61 of the easy-open adhesive 6 and the second surface 12, so that the battery 100 can be detached from the housing 7. And the glue-free area 62 of the easy-pull glue 6 is attached to the wrapping layer 3, so that the resistance of the easy-pull glue 6 can be reduced when the easy-pull glue 6 is pulled just beginning, and the possibility that the easy-pull glue 6 is broken by pulling can be reduced.
In the related art, the device module is wrapped by the wrapping layer with high viscosity, and due to the fact that the bonding force between the wrapping layer with high viscosity and the first insulating layer or the second insulating layer or the bonding force between the wrapping layer and the easy-to-pull glue is high, when the battery is pulled, stress concentration is easily generated on the position, contacted with the edge of the battery, of the easy-to-pull glue, and then the easy-to-pull glue is cut off by the device module.
According to the battery 100 of the electronic device 200 of the embodiment of the invention, the body module 1 and the device module 2 are integrated by the first insulating film 4 and the second insulating film 5, the glue-free area 62 is arranged on the easy-to-draw glue 6, and the glue-free area 62 is attached to the wrapping layer 3, so that when the easy-to-draw glue 6 is pulled, an external force can be transmitted to the whole battery 100, the body module 1, the device module 2 and the easy-to-draw glue 6 are uniformly stressed, and the possibility of stress concentration at the local position of the easy-to-draw glue 6 is reduced, thereby effectively preventing the easy-to-draw glue 6 from being broken, and simultaneously preventing the easy-to-draw glue 6 from deforming the film wrapped on the body module 1 or the device module 2, so that the body module 1 and the device module 2 can be conveniently detached from the shell. In addition, by arranging the non-adhesive region, the adhesion of adhesive substances on the easy-pull adhesive 6 to the body module 1 or the device module 2 can be effectively reduced, so that the battery 100 can still have certain surface finish in the disassembly process.
According to one embodiment of the present invention, the first insulating film 4, the second insulating film 5 each have a viscosity greater than that of the wrapping layer 3. Therefore, the structural strength of the device module 2 can be enhanced, the integrity of the body module 1 and the device module 2 can be improved, when the easy-pull adhesive 6 is pulled, external force can be transmitted to the whole battery 100, the body module 1, the device module 2 and the easy-pull adhesive 6 are uniformly stressed, and the possibility of stress concentration generated at the local position of the easy-pull adhesive 6 is reduced. To further enhance the structural strength of the device module 2 and prevent damage to the device module 2 when the easy-open glue 6 is pulled, a protection plate 21 may be provided inside the device module 2 in the examples of fig. 5, 7 and 8. Of course, the protective plate 21 may also be used to protect the electrical components 22 inside the device module 2.
According to one embodiment of the present invention, a through-hole 33 is provided in the wrapping layer 3 at a position where it is bonded to the first insulating film 4. As shown in fig. 1 and 5, the through-hole 33 is formed in the covering layer 3, and when the first insulating film 4 is attached to the covering layer 3, the first insulating film 4 covers the through-hole 33, the first insulating film 4 is pressed at a position having the through-hole 33, so that a part of the first insulating film 4 can be pressed into the through-hole 33, and the first insulating film 4 located in the through-hole 33 can be directly bonded to the device module 2, so that the connection between the body module 1 and the device module 2 is more stable, and the integrity of the body module 1 and the device module 2 can be further enhanced. Further, as shown in fig. 1, the through hole 33 may be spaced apart from each other, so that the connection stability between the body module 1 and the device module 2 may be further improved, and the integrity of the body module 1 and the device module 2 may be enhanced.
As shown in fig. 5 and 6, in order to further improve the integrity of the body module 1 and the device module 2, in some examples of the present invention, a part of the edge of the aluminum-plastic film 16 for wrapping the body module 1 extends into the device module 2 and is wrapped by the wrapping layer 3. Further, as shown in fig. 6, the first insulating film 4 or the second insulating film 5 covers the connection portion of the aluminum plastic film 16 and the device module 2. It can be understood that a part of the aluminum plastic film 16 extends into the wrapping layer 3, and the first insulating film 4 or the second insulating film 5 covers a connection portion of the aluminum plastic film 16 and the wrapping layer 3, so that the edge of the wrapping layer 3 can be prevented from being raised.
According to an embodiment of the present invention, as shown in fig. 5 to 8, the battery tab 13 of the body module 1 extends from the body module 1 and is wrapped by the wrapping layer 3, and the battery tab 13 includes the third surface 14 and the fourth surface 15 which are oppositely disposed, thereby allowing the battery 100 to have better integrity. The wrapping layer 3 may include a first wrapping portion 31 and a second wrapping portion 32 connected to the first wrapping portion 31, the first wrapping portion 31 wrapping a side of the battery tab 13 near the third surface 14, the second wrapping portion 32 wrapping a side of the battery tab 13 near the fourth surface 15, at least one of the first wrapping portion 31 and the second wrapping portion 32 extending meandering. It is understood that, within the device module 2, the wrapping layers 3 may be stacked to construct a multi-layer structure, thereby enhancing the structural strength of the device module 2 and preventing the device module 2 from being deformed during the pulling process by the easy-pull adhesive 6.
According to some embodiments of the invention, the part of the wrapping layer 3 attached to the pop-top glue 6 is a teflon film. It should be noted that the teflon film may be a film structure made of teflon, and the teflon may be referred to as Polytetrafluoroethylene (PTFE) or may be referred to as "non-stick coating", "easy-to-clean material", "plastic king" or "hala". The material has the characteristics of acid resistance, alkali resistance and resistance to various organic solvents. Meanwhile, the polytetrafluoroethylene has the characteristic of high temperature resistance, has extremely low friction coefficient and has the lubricating effect.
Of course, the structure of the wrapping layer 3 is not limited thereto, for example, in other embodiments of the present invention, the portion of the wrapping layer 3, which is attached to the pop-top adhesive 6, is coated with a teflon layer, thereby saving costs. For another example, the entire wrapping layer 3 is made of a teflon film, so that the process of the wrapping layer 3 can be simplified. For another example, the wrapping layer 3 is a SILICONE adhesive layer, which is an ointment like SILICONE part product that cures into a tough rubber-like solid when exposed to moisture in the air. The silicone adhesive is mainly classified into a deacetylated type, a dealcoholized type, a deaminated type and a depropanated type, and the polymer of which the chemical component is polydimethylsiloxane and silicon dioxide can be called silicone. The silicone adhesive is commonly used for bonding and sealing glass, so the silicone adhesive is commonly called as glass adhesive, has strong bonding force and high tensile strength, and has the characteristics of weather resistance, vibration resistance, moisture resistance, odor resistance and large adaptability to cold and heat changes.
In order to improve the connection stability of the battery 100 and other components, in one example of the present invention, as shown in fig. 2, the adhesive region 17 is provided on the side wall surface of the body module 1 to which the adhesive portion 61 is adhered, and the adhesiveness in the adhesive region 17 is gradually increased in the direction from the adhesive-free region 62 toward the adhesive portion 61. . That is, the second surface 12 of the body module 1 is provided with the adhesive region 17, and the adhesiveness in the adhesive region 17 is gradually increased in the direction from the adhesive-free region 62 toward the adhering portion 61.
It is to be understood that, in order to facilitate pulling up one end of the battery 100 by the easy-open adhesive 6, a material having a low viscosity may be provided at a position close to the end, and in order to enhance the connection stability and the firmness between the battery 100 and other components, a material having a high viscosity may be provided at a position close to the other end of the battery 100, the suburban area of the easy-open adhesive 6 is close to one end of the battery 100, and the bonding portion 61 of the easy-open adhesive 6 is close to the other end of the battery 100. For example, as shown in fig. 2, on the surface of the body module 1 connected to the adhering part 61 of the easy open glue 6, the adhesiveness of the adhering region 17 is gradually reduced in the left-to-right direction (left-to-right direction as shown in fig. 2).
In order to facilitate pulling the handle portion 63, in an example of the present invention, the handle portion 63 of the pop-top tape 6 may have a ring structure, a strip structure, or a sheet structure. According to one embodiment of the invention, the easy open glue 6 can be a plurality of spaced apart strips. Therefore, when the body module 1 and the device module 2 are detached from the shell 7 by using the easy-pull adhesive 6, external force can be applied to the plurality of easy-pull adhesives 6, so that the external force can be dispersed on the battery 100, and the battery 100 can be uniformly stressed.
In the example shown in fig. 2, the easy-open glue 6 is two. Further, the two easy-open adhesives 6 can be in a cross structure, and the reliability of connection between the adhesive tapes can be improved through the adhesive tapes in the cross structure, so that the failure of detachment caused by the breakage of the adhesive tapes in the detachment process of the battery 100 is prevented. Two easy-to-draw glues 6 can be alternately at body module 1's center, and two easy-to-draw glue 6's tip extends to four angles of body module 1 respectively, and bonds with four angles of body module 1 respectively. Through this structure, can increase the reliability that body module 1 and easy-to-draw glue 6 are connected to prevent that the fracture of easy-to-draw glue 6 from causing the dismantlement failure in the battery 100 dismantlement process. Of course, the arrangement of the two easy-open glues 6 is not limited to this, for example, the two easy-open glues 6 may be arranged in parallel with each other.
