[0047] Exemplary embodiments will be described in detail herein, examples of which are shown in the accompanying drawings. When the following description refers to the drawings, the same numbers in different drawings represent the same or similar elements unless otherwise indicated. The implementations described in the following exemplary embodiments do not represent all implementations consistent with the present application. Instead, they are merely examples of devices and methods consistent with some aspects of the present application as detailed in the appended claims.

[0048] Batteries are used as power sources in electronic devices to provide power to various electronic devices in the electronic devices. The housing of the electronic device usually forms a cavity for accommodating the battery, and the cavity has an opening through which the battery can be assembled into the cavity. The cavity can be called a battery compartment. When the electronic device is a mobile phone, the battery compartment can be formed on the middle frame so that the battery can be fixed to the middle frame, and the opening of the battery compartment can be covered by the back cover of the mobile phone.

[0049] In the related art, the battery can be fixed in the battery compartment by double-sided tape, however, this solution will make it difficult to conveniently disassemble the battery and the battery compartment. Alternatively, the battery can also be fixed in the battery compartment by an easy-tear sticker. The easy-tear sticker usually includes an adhesive body and a lifting body, wherein one side of the adhesive body is bonded to the battery, and the other side is bonded to the battery compartment by double-sided tape to fix the battery in the battery compartment; the lifting body and the adhesive body are weakly connected so that the lifting body can be torn apart relative to the adhesive body, so that the lifting body can be used as a handle to lift the battery and separate the battery from the battery compartment. However, when the battery is fixed by using an easy-tear sticker, in order to ensure that the lifting body and the adhesive body can be separated, the double-sided tape needs to avoid the weak connection area between the lifting body and the adhesive body, resulting in a reduction in the bonding area between the easy-tear sticker and the battery compartment, affecting the reliability of battery fixation.

[0050] Therefore, the present application provides a battery fixing device for fixing the battery in the battery compartment, which can ensure the reliability of battery fixing while making the battery easy to disassemble.

[0051] In order to make the objectives, technical solutions and advantages of the present application clearer, the implementation methods of the present application will be further described in detail below with reference to the accompanying drawings.

[0052] Figure 1 Schematic diagram of the structure of a battery fixing member and a battery provided in an embodiment of the present application. Figure 1 As shown, the battery includes a bottom surface 101, a top surface 102, and two side surfaces 103 arranged opposite to each other. When the battery 100 is placed in the battery compartment 300, the bottom surface 101 faces the bottom wall of the battery compartment 300, wherein the bottom wall of the battery compartment 300 faces the opening of the battery compartment 300; the top surface 102 faces the bottom surface 101, so that the top surface 102 faces the opening of the battery compartment 300; each side surface 103 is connected between the bottom surface 101 and the top surface 102.

[0053] like Figure 1 and Figure 2 As shown, the battery fixing member for fixing the battery 100 in the battery compartment 300 includes a carrier film layer 1 and an electrical adhesive layer 2. Among them, at least one side of the carrier film layer 1 is adhesive, and the carrier film layer 1 is configured to be bonded to the battery 100 and cover at least part of the bottom surface 101, at least one side surface 103 and at least part of the top surface 102 of the battery 100. In other words, the carrier film layer 1 extends from the bottom surface 101 of the battery 100 through a side surface 103 to the top surface 102 of the battery 100. In addition, the carrier film layer 1 has a conductive layer 121, and the conductive layer 121 is exposed on the top surface 102, so that the user can see the conductive layer 121 from the top surface 102 of the battery 100.

[0054] The electrical adhesive layer 2 has adhesive properties on both opposite sides, one side of the electrical adhesive layer 2 is bonded to the side of the carrier film layer 1 facing away from the battery 100 and in contact with the conductive layer 121, and the other side is configured to be bonded to the inner wall of the battery compartment 300, wherein the electrical adhesive layer 2 is configured to lose its adhesiveness when power is supplied.

[0055] The battery fixing device provided in the embodiment of the present application has a supporting film layer 1 bonded to the battery 100 and bonded to the wall of the battery compartment 300 through the electrical adhesive layer 2, so that the battery 100 can be reliably fixed in the battery compartment 300; and because the electrical adhesive layer 2 loses its viscosity when energized, when the battery 100 needs to be disassembled from the battery compartment 300, a voltage is applied to the conductive layer 121 exposed on the top surface 102 of the battery 100 and the wall of the battery compartment 300 bonded to the electrical adhesive layer 2 to energize the electrical adhesive layer 2, so that the battery 100 can be separated from the battery compartment 300, so that the battery 100 can be easily disassembled.

[0056] It can be seen that the battery fixing device provided in the embodiment of the present application can ensure the reliability of the fixation of the battery 100 while making the battery 100 easy to disassemble. Compared with the solution of fixing the battery by easy-tear stickers in the related art, since the electrical adhesive layer 2 loses its viscosity when energized, it will not affect the pulling out of the battery 100 from the battery compartment 300. The electrical adhesive layer 2 does not need to avoid the weak connection area between the pulling body and the adhesive body, which increases the bonding area of ​​the electrical adhesive layer 2 (the bonding area can be increased by 5%-10%), thereby improving the connection strength between the battery 100 and the battery compartment 300; compared with the solution of fixing the battery by double-sided tape in the related art, the battery 100 can be easily separated from the battery compartment 300 by energizing the electrical adhesive layer 2, which reduces the difficulty of disassembling the battery 100.

[0057] In some embodiments, the electrical adhesive layer 2 can be adhered between the bottom surface 101 of the battery 100 and the bottom wall of the battery compartment 300; or the electrical adhesive layer 2 can be adhered between the side surface 103 of the battery 100 and the side wall of the battery compartment 300; or the electrical adhesive layer 2 can be basically consistent with the shape of the supporting film layer 1, thereby covering at least part of the bottom surface 101, at least one side surface 103 and at least part of the top surface 102 of the battery 100.

[0058] In some embodiments, the side of the carrier film layer 1 close to the battery 100 (hereinafter referred to as the bonding side) may be sticky as a whole. The bonding strength of different areas in the bonding side may be uniform or differentially distributed. In some embodiments, the bonding strength of the portion of the carrier film layer 1 covering the top surface 102 of the battery 100 is sufficient to be separated from the battery 100 under the action of an external force, so that when the electrical adhesive layer 2 is energized and loses its stickiness, the portion can be torn off from the top surface 102 of the battery 100 and used as a handle to lift the battery 100, and then the battery 100 can be disassembled from the opening of the battery compartment 300.

[0059] In some embodiments, the conductive layer 121 may cover at least a portion of the top surface 102 of the battery 100. In this case, when disassembling the battery 100, the conductive layer 121 may be torn apart relative to the top surface 102 of the battery 100 and then stand up. Then, the conductive layer 121 and the side wall of the battery compartment 300 may be electrified to make the electrical adhesive layer 2 lose its stickiness. Then, the battery 100 may be lifted up through the standing conductive layer 121 and the battery 100 may be disassembled from the opening of the battery compartment 300.

[0060] In some embodiments, the bottom surface 101 and the top surface 102 of the battery 100 are two surfaces arranged opposite to each other in the thickness direction. The two side surfaces 103 may be arranged opposite to each other in the width direction of the battery 100, so that the battery fixing member can lift the battery 100 from the long side of the battery 100; or the two side surfaces 103 may be arranged opposite to each other in the length direction of the battery, so that the battery fixing member can lift the battery 100 from the short side of the battery 100.

[0061] In some embodiments, the carrier film layer 1 may be an integrally formed component, and when the electrical adhesive layer 2 loses its viscosity after being energized, the carrier film layer 1 may adhere to the battery 100 and be disassembled together with the battery 100. In other embodiments, the carrier film layer 1 may be a split component, and when the electrical adhesive layer 2 loses its viscosity after being energized, a portion of the carrier film layer 1 may be disassembled together with the battery 100, and the other portion remains in the battery compartment 300.

[0062] like Figure 1 , Figure 2 and Figure 3 As shown, the carrying film layer 1 includes a carrying portion 11 and a handle portion 12, wherein the carrying portion 11 is configured to cover a bottom surface 101 of the portion, and the handle portion 12 is configured to cover the bottom surface 101 of the portion, at least one side surface 103 and at least a portion of the top surface 102.

[0063] When the carrier film layer 1 is an integrally formed component, the carrier portion 11 and the handle portion 12 are an integrally formed structure. For example, the carrier film layer 1 can be a steel-plastic film. Alternatively, when the carrier film layer 1 is a split component, the carrier portion 11 and the handle portion 12 are separated, and the carrier portion 11 and the handle portion 12 are connected via an electrical adhesive layer 2.

[0064] In some embodiments, the electrical adhesive layer 2 loses its viscosity only when the area connected to the positive and negative electrodes of the power source is connected at the same time, that is, the portion of the electrical adhesive layer 2 that contacts the conductive layer 121 and the inner wall of the battery compartment 300 at the same time loses its viscosity when power is turned on. Therefore, by the differentiated arrangement of the carrier portion 11 and the handle portion 12, for example, the conductive layer 121 is not included in the carrier portion 11, or the conductive layer 121 in the carrier portion 11 does not contact the electrical adhesive layer 2, the electrical adhesive layer 2 connected between the carrier portion 11 and the battery compartment 300 can always maintain viscosity, while the electrical adhesive layer 2 bonded between the handle portion 12 and the battery compartment 300 can lose its viscosity when power is turned on, so that when the battery 100 is disassembled, the handle portion 12 can be bonded to the battery 100 and used as a handle to lift the battery 100 and be disassembled from the battery compartment 300 together with the battery 100, while the carrier portion 11 is bonded to the electrical adhesive layer 2 and remains in the battery compartment 300.

[0065] Compared with the solution of fixing the battery by an easy-tear sticker in the related art, the handle portion 12 and the carrying portion 11 separated from each other are fixed together by the electrical adhesive layer 2. When the electrical adhesive layer 2 loses its stickiness by applying a voltage to it, the handle portion 12 can be separated from the electrical adhesive layer 2 and the carrying portion 11 at the same time, which further reduces the difficulty of disassembling the battery 100.

[0066] In some embodiments, the side of the handle portion 12 facing the battery 100 is sticky, so as to facilitate lifting the battery 100 and removing it from the battery compartment 300; and the side of the carrying portion 11 facing the battery 100 is also sticky, so that when the electrical adhesive layer 2 is not energized, the fixing stability of the battery 100 can be further improved by increasing the bonding area of ​​the battery 100.

[0067] In the present application embodiment, Figure 4 As shown, the carrier 11 may include a substrate layer 111 and an adhesive coating 112 , wherein the adhesive coating 112 is located on a side of the substrate layer 111 close to the battery 100 , and the adhesive coating 112 includes a plurality of glue dots 1121 , and the plurality of glue dots 1121 are evenly spaced apart on the substrate layer 111 .

[0068] In some embodiments, the substrate layer 111 is an insulating layer and can be attached to the electrical adhesive layer 2, so that when a voltage is applied to the electrical adhesive layer 2, the portion of the electrical adhesive layer 2 attached to the substrate layer 111 will not lose its adhesiveness due to the energization. Exemplarily, the substrate layer 111 can be made of PET (polyethylene terephthalate) material.

[0069] The adhesive coating 112 can be formed by coating a weak glue on the substrate layer 111, so that the adhesive coating 112 has adhesiveness. And because the weak glue is evenly coated in different areas on the substrate layer 111, the adhesive coating 112 is evenly distributed between the multiple glue points formed on the substrate layer 111. Compared with the scheme of forming an adhesive layer by coating a strong glue on the substrate layer and then patterning and killing the glue, the scheme of forming the adhesive coating 112 by coating a weak glue as a whole, the carrier 11 can be directly die-cut after the weak glue is coated as a whole, reducing the cost of the battery fixing (die-cutting can save 10%-20% of materials) and the difficulty of processing. In order to ensure that when the handle 12 lifts the battery 100, the carrier 11 is separated from the battery 100 and continues to be bonded to the electrical adhesive layer 2, the bonding strength of the electrical adhesive layer 2 can be greater than the bonding strength of the bonding coating 112 in the carrier 11.

[0070] It is understood that bonding strength refers to the stress required to destroy the interface between the adhesive in the adhesive and the adherend or its vicinity under the action of external force, and bonding strength is also called bonding strength. In the embodiment of the present application, the bonding strength of the electrical bonding layer 2 can be understood as the bonding strength between the electrical bonding layer 2 and the battery compartment 300 (or the load-bearing part 11), and the bonding strength of the bonding coating 112 can be understood as the bonding strength between the bonding coating 112 and the battery 100.

[0071] In the present application embodiment, Figure 4 and Figure 5 As shown, the supporting portion 11 further includes a reinforcing adhesive layer 113 . The reinforcing adhesive layer 113 is located on a side of the substrate layer 111 away from the battery 100 .

[0072] In some embodiments, the electrical adhesive layer 2 can be disposed only in an electrically conductive area (for example, in the middle frame 400 of an electronic device), so that the electrical adhesive layer 2 can be easily peeled off by energizing the electrical adhesive layer 2; and if the electrical adhesive layer 2 is disposed in a non-conductive area (for example, a circuit board 500 or a heat spreader 600 in an electronic device) over a large area, the electrical adhesive layer 2 is difficult to peel off because the non-conductive area cannot be energized. In other words, the bonding area of ​​the electrical adhesive layer 2 in the battery compartment 300 is limited. In this case, when the bonding area of ​​the electrical adhesive layer 2 is insufficient, the bonding strength of the battery fixing can be increased by additionally providing a sticky reinforcing adhesive layer 113, thereby ensuring the fixing reliability of the battery 100.

[0073] In addition, when the reinforcing adhesive layer 113 is provided, the adhesive strength of the reinforcing adhesive layer 113 can be set to be greater than the adhesive strength of the adhesive coating 112 in the carrier 11, so that the carrier 11 is retained in the battery compartment 300 by the reinforcing adhesive layer 113. In other words, at least one of the adhesive strength of the reinforcing adhesive layer 113 and the adhesive strength of the electrical adhesive layer 2 can be greater than the adhesive strength of the adhesive coating 112.

[0074] In some embodiments, the adhesive strength of the carrier portion 11 is different from the adhesive strength of the handle portion 12. For example, the adhesive strength of the carrier portion 11 may be less than the adhesive strength of the handle portion 12, so that when the battery 100 is lifted and disassembled from the battery compartment 300, the handle portion 12 can remain bonded to the battery 100, while the adhesive strength of the carrier portion 11 (adhesive coating 112) can enable the carrier portion 11 to be separated from the battery 100. In addition, the adhesive strength of the handle portion 12 can also be sufficient to be separated from the top surface 102 of the battery 100 under external force, so that when the battery 100 needs to be lifted, the portion of the handle portion 12 covering the top surface 102 can be torn apart and stand up relative to the top surface 102 to facilitate user operation.

[0075] In the present application embodiment, Figure 6 As shown, the handle portion 12 may include a first insulating layer 122 , a second insulating layer 123 and a conductive layer 121 ; the conductive layer 121 is located between the first insulating layer 122 and the second insulating layer 123 , and the first insulating layer 122 is adhesive and is located on a side of the conductive layer 121 close to the battery 100 .

[0076] By sandwiching the conductive layer 121 between the first insulating layer 122 and the second insulating layer 123, electrical insulation can be achieved between the conductive layer 121 and the battery 100 and the side wall of the battery compartment 300. In addition, the second insulating layer 123 can provide a protective function (for example, including a fireproof and punctureproof function), thereby protecting the side of the battery 100 and preventing the battery 100 from being damaged by improper disassembly by the user.

[0077] Exemplarily, the first insulating layer 122 may be an acrylic pressure-sensitive adhesive, and its thickness may be in the range of 18 μm-22 μm, for example, 20 μm; the second insulating layer 123 may be an acrylic paint layer, and its thickness may be in the range of 8 μm-12 μm, for example, 10 μm; the conductive layer 121 may be a metal foil layer, and its thickness may be in the range of 18 μm-22 μm, for example, 20 μm. For example, the handle portion 12 may be a steel-plastic film, so that the conductive layer 121 is a steel foil layer; or the handle portion 12 may be an aluminum-plastic film, so that the conductive layer 121 is an aluminum foil layer.

[0078] The conductive layer 121 may be exposed relative to the second insulating layer 123 at a portion covering the top surface 102 and a portion covering the electrical adhesive layer 2 , so that a user may apply a voltage to the electrical adhesive layer 2 through the exposed conductive layer 121 .

[0079] In some embodiments, the battery fixing member may include only one sub-handle portion 124, so that the battery 100 can be removed from the battery compartment 300 by pulling from one side. Figure 1 , Figure 2 , Figure 3 and Figure 5 As shown, in order to enable the battery 100 to be lifted more stably for user operation, the handle portion 12 may include two sub-handle portions 124 , wherein each sub-handle portion 124 is configured to cover a portion of the bottom surface 101 and a side surface 103 .

[0080] like Figure 5 As shown, the two sub-handles 124 are separated, the carrying portion 11 is located between the two sub-handles 124, and the carrying portion 11 and the two sub-handles 124 are respectively connected by the electrical adhesive layer 2. In this way, when the battery 100 needs to be disassembled, an electrical signal can be provided to the two sub-handles 124 from the two side surfaces 103 of the battery 100 to apply a voltage, so that the two sub-handles 124 are separated from the carrying portion 11, and then the battery 100 is smoothly lifted from the opposite sides of the battery 100 through the two sub-handles 124.

[0081] In other embodiments, both sub-handle portions 124 may be connected to the load-bearing portion 11 , so that the load-bearing film layer 1 may be an integrally formed component; or one of the sub-handle portions 124 may be separated from the load-bearing portion 11 , while the other sub-handle portion 124 may be directly connected to the load-bearing portion 11 .

[0082] In the case where the battery holder has two sub-handles 124 and both sub-handles 124 are connected to the carrier 11 via the electrical adhesive layer 2, as shown in FIG. Figure 3 and Figure 7 As shown, the electrical adhesive layer 2 may include a first sub-adhesive layer 21 and a second sub-adhesive layer 22 that are separated from each other, and the first sub-adhesive layer 21 and the second sub-adhesive layer 22 are respectively connected to different sub-handle portions 124 .

[0083] In some embodiments, the electrical adhesive layer 2 connected between the carrier portion 11 and one of the sub-handle portions 124 may extend continuously, and its extension length is substantially equal to the extension length of the carrier portion 11 and the handle portion 12. The extension length may be, for example, a dimension along the length direction of the battery 100.

[0084] In other embodiments, when the battery fixing member has at least one sub-handle portion 124 connected to the carrying portion 11 through the electrical adhesive layer 2, as shown in FIG.
