[0035] Embodiment one

[0036] Referring to Figures 1 to 6 As shown, the battery assembly provided by the present application can be applied to terminal devices such as mobile phones.

[0037] Referring to Figure 5 and Figure 6 As shown, the mobile phone mainly consists of a back cover 117, a battery module 118, an adapter plate 119, a mobile phone shell 120, a screen fixing glue 121 and a screen 122, the battery module 118 is installed in the battery compartment 101 provided in the mobile phone shell 120, and the battery module 118 is connected to the mainboard in the mobile phone shell 120 through the adapter plate 119, the back cover 117 is buckled on the back of the mobile phone shell 120, and the screen 122 is connected to the front of the mobile phone shell 120 through the screen fixing glue 121. The battery module 118 mainly consists of a head paper 123, a PCM protection plate 124, a groove double-sided adhesive tape 125, a top sealing paper 126, a silica gel pad 127, a battery body 102, a side paper 128, a tail paper 129 and an adhesive assembly 103.

[0038] Specifically, the battery assembly provided in this application includes a battery compartment 101, a battery body 102, and an adhesive assembly 103. The battery body 102 can be installed inside the battery compartment 101 through an opening in the battery compartment 101, and the adhesive assembly 103 is used to adhesively fix the battery body 102 to the battery compartment 101. When disassembling the battery body 102, the adhesiveness of the adhesive assembly 103 can be reduced to make the battery body 102 easier to remove from the battery compartment 101.

[0039] Specifically, the adhesive assembly 103 includes a conductive layer 104, an electrolytic adhesive layer 105, and a first insulating layer 106. The conductive layer 104 includes a first main body portion 107 and a first extension portion 108.

[0040] The first main body 107 is attached to the bottom surface of the battery body 102. The bottom surface is one side surface of the battery body 102 in the thickness direction, that is, the large surface of the battery body 102 opposite to the bottom of the battery compartment 101 (from...). Figure 1 and Figure 2 From a mid-range perspective, the bottom surface is the back of the battery body 102. An electrolytic adhesive layer 105 is covered on the first main body 107. The electrolytic adhesive layer 105 is used to connect with the bottom of the battery compartment 101, thereby achieving the bonding and fixation of the battery body 102.

[0041] The first extension 108 is attached to the circumferential side surface of the battery body 102, and the circumferential side surface is perpendicularly connected to the bottom surface. Figure 1 and Figure 2 The circumferential side shown is located at one end of the battery body 102 in the width direction. The first extension 108 is elongated, and at the connecting edge between the bottom surface and the circumferential side, one end of the first extension 108 in the length direction is connected to the first main body 107. The other end of the first extension 108 extends along the circumferential side to the opposite side of the bottom surface (from...). Figure 1 and Figure 2 From a mid-range perspective, this side is the front side of the battery body 102. On this side, the first extension 108 bends towards the opening edge of the battery compartment 101 so that the first extension 108 fits against the opening edge of the battery compartment 101. A first insulating layer 106 covers the surface of the first extension 108 facing the battery compartment 101 to insulate and isolate the first extension 108 from the battery compartment 101.

[0042] In actual application, when the battery body 102 is disassembled, the positive and negative poles of the external power supply are respectively connected to the first extension part 108 on the front side of the battery body 102 and the battery compartment 101, and the first insulation layer 106 is arranged between the first extension part 108 and the side wall of the battery compartment 101, so that short circuit can be avoided. The first extension part 108 is connected with the first main part 107, so that the conductive layer 104 forms a conductive channel, and the first extension part 108 and the first main part 107 are in the same potential. Since the two side surfaces of the electrolytic adhesive layer 105 are respectively in contact with the battery compartment 101 and the conductive layer 104, the power supply can form a suitable voltage difference on the two side surfaces of the electrolytic adhesive layer 105, so that the adhesion of the electrolytic adhesive layer 105 is greatly reduced, and the battery body 102 is more easily disassembled.

[0043] In addition, since the first extension part 108 is bent to the opening edge of the battery compartment 101, the arrangement of the first extension part 108 does not increase the thickness of the battery body 102, and thus does not affect the capacity of the battery body 102; and when the pen is in contact with the first extension part 108, the problem that the battery body 102 is pressed and depressed or punctured by the pen can be avoided.

[0044] The battery assembly provided by the application can fix the battery body 102 and the battery compartment 101 by the bonding assembly 103, and when the battery body 102 is disassembled, the electrolytic adhesive layer 105 can be electrified to reduce the adhesion thereof, so that the battery body 102 is more easily separated from the battery compartment 101, and the problem that the battery body 102 is damaged and the battery compartment 101 is deformed can be avoided.

[0045] In the optional scheme of the embodiment, the battery compartment 101 is provided with a receiving groove, and the battery body 102 is installed in the receiving groove. The opening edge of the battery compartment 101 is the groove edge of the receiving groove, and the groove edge of the receiving groove is provided with a first embedding groove 109, the first embedding groove 109 is communicated with the receiving groove, and the end of the first extension part 108 can extend into the first embedding groove 109 from the receiving groove. The one end of the first extension part 108 is arranged in the first embedding groove 109, so that the thickness of the first extension part 108 is not increased.

[0046] In the optional scheme of the embodiment, the groove wall of the receiving groove is provided with a second embedding groove 110, the second embedding groove 110 is communicated with the first embedding groove 109, and the other end of the first extension part 108 is arranged in the second embedding groove 110, that is, the first extension part 108 can extend into the first embedding groove 109 along the second embedding groove 110. In this way, only the second embedding groove 110 with a smaller size is arranged on the groove wall of the receiving groove at the position corresponding to the first extension part 108, so as to accommodate the first extension part 108, and the size of the opening of the receiving groove does not need to be changed, so that the influence of the thickness of the first extension part 108 on the opening size of the battery compartment 101 is reduced.

[0047] In an optional solution of the embodiment, the sum of the thickness of the first extension 108 and the first insulating layer 106 is less than the groove depth of the first embedding groove 109 and the second embedding groove 110, so that the first insulating layer 106 and the conductive layer 104 can be completely embedded in the first embedding groove 109 and the second embedding groove 110, which is more conducive to the miniaturization of the device.

[0048] In an optional solution of the embodiment, the conductive layer 104 is a metal foil. Optionally, the metal foil is an aluminum foil, a copper foil or the like conductive foil material.

[0049] In an optional solution of the embodiment, the bonding assembly 103 further comprises a double-sided adhesive layer 111, which is located between the conductive layer 104 and the battery body 102, so as to connect the conductive layer 104 and the battery body 102, i.e. to attach the conductive layer 104 to the surface of the battery body 102.

[0050] In an optional solution of the embodiment, as shown in Figure 4 the double-sided adhesive layer 111 comprises a second main body part 112 and a second extension part 113. The second main body part 112 is an adhesive layer coated on the first main body part 107 of the conductive layer 104, and the first main body part 107 can be bonded to the bottom surface of the battery body 102 through the second main body part 112. The second extension part 113 is an adhesive layer coated on the first extension part 108 of the conductive layer 104.

[0051] Further, the bonding assembly 103 further comprises a second insulating layer 114. The second insulating layer 114 is located between the second extension part 113 and the battery body 102, and the second insulating layer 114 is bonded to the first extension part 108 through the second extension part 113. The second insulating layer 114 covers the first extension part 108 of the conductive layer 104, which can avoid the problem of friction and fracture of the metal foil caused by the contact between the metal foil and the battery body 102.

[0052] In an optional solution of the embodiment, at the groove edge of the accommodating groove, the coverage range of the second insulating layer 114 is less than the coverage range of the second extension part 113, i.e. the coverage range of the adhesive is larger, so as to reliably bond the edge of the second insulating layer 114 and avoid the problem of the edge of the second insulating layer 114 being raised.

[0053] Preferably, for the second insulating layer 114 in the form of a long strip, the end part of the second insulating layer 114 in the length direction is more prone to be raised, and the present application further limits that the end part of the second insulating layer 114 in the length direction is shorter than the second extension part 113, so that the bonding and fixing effect of the second extension part 113 on the second insulating layer 114 is more firm.

[0054] In an optional solution of the embodiment, as shown in Figure 4As shown, at the groove edge of the accommodating groove, the second insulating layer 114 and the second extension 113 are correspondingly provided with a defect part 115 to expose the conductive layer 104, so that the conductive layer 104 at this position can be externally connected to a power supply.

[0055] In this embodiment, part of the material at the end edge of the second insulating layer 114 and the end edge of the second extension 113 can be removed to form a groove-shaped defect part 115, thereby exposing the internal conductive layer 104; or a through hole is correspondingly formed on the second insulating layer 114 and the second extension 113 to form a circular or other shape defect part 115, thereby exposing the internal conductive layer 104.

[0058] Reference Figure 4 As shown, in the optional scheme of this embodiment, the bonding assembly 103 further comprises a protective film 116, which can be detachably covered on the electrolytic adhesive layer 105 and the first extension 108.

[0059] In this embodiment, before the battery body 102 is loaded into the battery compartment 101, the double-sided adhesive layer 111 of the bonding assembly 103 is connected with the battery body 102, and the bonding assembly 103 is attached to the battery body 102, and the side of the electrolytic adhesive layer 105 away from the conductive layer 104 is covered with a protective layer (specifically, a blue film), to avoid that foreign matters such as dust in the outside environment adhere to the electrolytic adhesive layer 105 and affect its performance. When the battery body 102 is loaded into the battery compartment 101, the protective layer is first torn off, and then the battery body 102 is placed into the battery compartment 101, and the electrolytic adhesive layer 105 is bonded and fixed with the battery compartment 101.
