One of the first and second connecting pieces serves as a negative electrode film, and the other as a positive electrode film. The first connecting piece is used to bond the battery and the battery compartment. The first and second connecting pieces are connected by electrolytic adhesive, utilizing the adhesive's stickiness and its electrolytic properties in an electric field to facilitate battery assembly and disassembly. However, in existing battery structures, the electrolytic adhesive is flush with all outer edges of the first connecting piece, making it prone to short-circuiting with all outer edges of the first connecting piece when the second connecting piece is bent.

[0025] This utility model provides a battery structure, referring to... Figures 1-4 The battery consists of a battery 1, a first connecting piece 2, an electrolytic adhesive 3, and a second connecting piece 4. The first connecting piece 2 is bonded to the bottom of the battery 1 and has a first external portion 21. The second connecting piece 4 has a second main body portion 41 and a second external portion 42 rotatably connected to the second main body portion 41. The second main body portion 41 is used to bond the battery compartment 5 and is located at the bottom of the first connecting piece 2. The second external portion 42 protrudes from the first connecting piece 2, bypasses the side of the battery 1, and is detachably connected to the top of the battery 1. The electrolytic adhesive 3 is located at the bottom of the battery 1 and is bonded to the first connecting piece 2 and the second connecting piece 4. The first external portion 21 and the second external portion 42 are used to be in a detached state between the second external portion 42 and the top of the battery 1, and after the second external portion 42 is rotated relative to the first connecting piece 2 to a preset angle, it is connected to a conductive circuit so that the electrolytic adhesive 3 is unbonded.

[0026] As an example, the battery structure includes a battery 1, a first connecting piece 2, an electrolytic adhesive 3, and a second connecting piece 4. The first connecting piece 2 has a first external portion 21 for connecting to a power-conducting device. The second connecting piece 4 has a second main body portion 41 and a second external portion 42 rotatably connected to the second main body portion 41. The second external portion 42 protrudes from the first connecting piece 2, bypasses the side of the battery 1, and is detachably connected to the top of the battery 1. The second external portion 42 is used to connect to a power-conducting device. When it is necessary to install the battery 1, the first connecting piece 2 is glued to the bottom of the battery 1, the second main body portion 41 is glued to the battery compartment 5, and the second external portion 42 bypasses the side of the battery 1 and is fixed to the top of the battery 1, so as to realize the installation of the battery 1 in the battery compartment 5. When battery 1 needs to be removed, the second external part 42 is in a disassembled state from the top of battery 1. After the second external part 42 is rotated to a preset angle relative to the first connecting piece 2 (specifically, all outer edges of the first connecting piece 2), the first external part 21 and the second external part 42 are connected into a conductive circuit to de-adhere the electrolytic adhesive 3. Specifically, an electrical device is used to energize the second connecting piece 4 and the first connecting piece 2, forming a conductive circuit between them. At this time, the electrolytic adhesive 3 between the second connecting piece 4 and the first connecting piece 2 can be electrolyzed and de-adheded in the electric field environment, thus facilitating the removal of battery 1 from battery compartment 5. At the same time, the electrolytic adhesive 3 is melted and leaves no residue in battery compartment 5. This reduces the difficulty of installing and removing battery 1 and improves the efficiency of battery installation and removal. The first connecting piece 2 and the second connecting piece 4 are both metal films, such as aluminum films.

[0027] In this example, when the battery 1 is removed, the second external part 42 is in a disassembled state from the top of the battery 1. The second external part 42 is rotated to a preset angle relative to all the outer edges of the first connecting piece 2. This creates a gap between the second external part 42 and all the outer edges of the first connecting piece 2, thus separating the second external part 42 from all the outer edges of the first connecting piece 2. This ensures that the second connecting piece 4 will not come into contact with the first connecting piece 2 and short-circuit, effectively solving the risk of short circuit.

[0028] In one embodiment, reference is made to Figure 3 and Figure 4 The first connecting piece 2 has an extension 22, which is bonded to the side of the battery 1 and separates the side of the battery 1 from the second external part 42.

[0029] As an example, the first connecting piece 2 has an extension 22. During installation, the extension 22 is bonded to the side of the battery 1, separating the side of the battery 1 from the second external part 42. By attaching the extension 22 to the side of the battery 1, corner support can be provided. During the disassembly of the battery 1, the second external part 42 is pulled out of the right-angle path. There is an angle between the surface of the extension 22 away from the battery 1 and the second external part 42. That is, the second external part 42 rotates to a preset angle relative to all the outer edges of the first connecting piece 2. This creates a gap between the second external part 42 and all the outer edges of the first connecting piece 2, achieving separation between the second external part 42 and all the outer edges of the first connecting piece 2. This ensures that the second connecting piece 4 will not come into contact with the first connecting piece 2 and short-circuit, effectively solving the risk of short circuit.

[0030] In one embodiment, reference is made to Figure 3 and Figure 4 The extension length of the extension portion 22 is greater than 2 mm.

[0031] As an example, the extension length of the extension 22 is greater than 2mm, which ensures that the extension 22 fits snugly against the side of the battery 1 and provides corner support. During the disassembly of the battery 1, the second external part 42 is pulled out of the non-right-angle path. There is an angle between the surface of the extension 22 away from the battery 1 and the second external part 42. That is, the second external part 42 rotates to a preset angle relative to all the outer edges of the first connecting piece 2. This creates a gap between the second external part 42 and all the outer edges of the first connecting piece 2, thereby separating the second external part 42 from all the outer edges of the first connecting piece 2 and ensuring that the second connecting piece 4 will not short-circuit with the first connecting piece 2, effectively solving the short-circuit risk.

[0032] In one embodiment, reference is made to Figures 2-4 The thickness of electrolytic adhesive 3 is 0.05-0.2mm.

[0033] As an example, the thickness of the electrolytic adhesive 3 is 0.05-0.2mm. This setting ensures that the first connecting piece 2 and the second connecting piece 4 are effectively connected together. At the same time, it can avoid the electrolytic adhesive 3 taking too long to untie. It can also ensure that when the second external part 42 rotates to a preset angle relative to all the outer edges of the first connecting piece 2, there is a sufficient gap between the second external part 42 and all the outer edges of the first connecting piece 2, ensuring that the second connecting piece 4 will not come into contact with the first connecting piece 2 and short-circuit, thus effectively solving the risk of short circuit.

[0034] In one embodiment, reference is made to Figure 3 and Figure 4 The preset angle is greater than or equal to 30°.

[0035] As an example, the preset angle is limited according to actual needs. When the preset angle is greater than or equal to 30 degrees, such as 45 degrees, it can ensure that the second outer part 42 is separated from all the outer edges of the first connecting piece 2, and the second connecting piece 4 will not short-circuit with the first connecting piece 2, effectively solving the short-circuit risk.

[0036] In one embodiment, the battery structure further includes an adhesive component bonded between the second external portion 42 and the top of the battery 1. The adhesive component may be double-sided adhesive. As an example, the battery structure also includes an adhesive component. During installation, the adhesive component is bonded between the second external portion 42 and the top of the battery 1, thereby fixing the second external portion 42 to the top of the battery 1 and preventing the second external portion 42 from shifting and short-circuiting due to contact with the first connecting piece 2. In one embodiment, reference is made to Figure 1 and Figure 3 The shape of the second main body 41 is the same as or different from the shape of the bottom of the battery 1; the second external part 42 is a strip-shaped external part.

[0037] As an example, the shape of the second main body 41 is designed according to actual needs. The shape of the second main body 41 can be the same as or different from the shape of the bottom of the battery 1, as long as the first connecting piece 2 and the second connecting piece 4 are connected. The second external part 42 is a strip-shaped external part, which reduces the finished area of ​​the second connecting piece 4 while ensuring the connection strength. This can significantly reduce the amount of waste generated in the die-cutting process, thereby reducing production costs and helping to reduce the weight and cost of the battery structure.

[0038] In one embodiment, reference is made to Figure 1 and Figure 2 The first connecting piece 2 also has a first main body 23, which is adhered to the bottom of the battery 1, and a first external part 21 that wraps around the side of the battery 1 and extends to the top of the battery 1.

[0039] As an example, the first connecting piece 2 also has a first main body 23. During installation, the first main body 23 is bonded to the bottom of the battery 1, and the first external part 21 bypasses the side of the battery 1 and extends to the top of the battery 1. This makes it easy to connect the first external part 21 to an external circuit to form a conductive circuit when the battery 1 needs to be removed, so as to de-adhere the electrolytic adhesive 3 and facilitate the installation and removal of the battery 1.

[0040] In one embodiment, reference is made to Figure 1 and Figure 2 One end of the first external part 21 is attached to the side of the battery 1, and the other end is attached to the top of the battery 1.

[0041] As an example, during installation, one end of the first external part 21 is glued to the side of the battery 1 and the other end is glued to the top of the battery 1, so that the first external part 21 is installed on the side and top of the battery 1. When it is necessary to remove the battery 1, it is convenient to connect the first external part 21 to the external circuit to form a conductive circuit, so that the electrolytic adhesive 3 can be unattached, thus facilitating the installation and removal of the battery 1.

[0042] In one embodiment, reference is made to Figure 1 and Figure 2 The shape of the first main body 23 is the same as or different from the shape of the bottom of the battery 1; the first external part 21 is a strip-shaped external part.

[0043] As an example, the shape of the first main body 23 is designed according to actual needs. The shape of the first main body 23 can be the same as or different from the shape of the bottom of the battery 1, as long as the first connecting piece 2 and the second connecting piece 4 can be connected. The first external part 21 is a strip-shaped external part, which reduces the finished area of ​​the first connecting piece 2 while ensuring the connection strength. This can significantly reduce the amount of waste generated in the die-cutting process, thereby reducing production costs and helping to reduce the weight and cost of the battery structure.

[0044] In one embodiment, reference is made to Figures 2-4 The first connecting piece 2 includes a first adhesive layer 24 and a first conductive layer 25. The first adhesive layer 24 is bonded between the battery 1 and the first conductive layer 25. The second connecting piece 4 includes a second adhesive layer 43 and a second conductive layer 44. The second adhesive layer 43 is used to bond between the battery compartment 5 and the second conductive layer 44. Electrolytic adhesive 3 is disposed between the first conductive layer 25 and the second conductive layer 44.

[0045] As an example, the first connecting piece 2 includes a first adhesive layer 24 and a first conductive layer 25, and the second connecting piece 4 includes a second adhesive layer 43 and a second conductive layer 44. During installation, the first adhesive layer 24 is bonded to the battery 1, and the second adhesive layer 43 is bonded to the battery compartment 5, thereby enabling the battery 1 to be installed in the battery compartment 5 through the connecting structure. When it is necessary to remove the battery 1, an electrical device is used to energize each second connecting piece 4 and the first connecting piece 2, so that each second connecting piece 4 and the first connecting piece 2 form a conductive circuit. At this time, the electrolytic adhesive 3 between each second connecting piece 4 and the first connecting piece 2 can be electrolyzed and debonded in the electric field environment, thereby facilitating the removal of the battery 1 from the battery compartment 5. At the same time, the electrolytic adhesive 3 is melted and no adhesive residue remains in the battery compartment 5. This can reduce the difficulty of installing and removing the battery 1 and improve the efficiency of battery 1 installation and removal.

[0046] In one embodiment, the battery structure further includes a release film disposed on the side of the second adhesive layer 43 opposite to the second conductive layer 44.

[0047] As an example, the battery structure also includes a release film. When the battery structure is not in use, the release film is placed on the side of the second adhesive layer 43 facing away from the second conductive layer 44. As a temporary protective layer, the release film effectively blocks dust, moisture, oil, and other contaminants from contacting the second adhesive layer 43 and the second conductive layer 44, preventing a decrease in adhesiveness or degradation of conductivity, and preventing scratches or corrosion of the conductive layer from affecting signal transmission or current conduction. When the battery structure is in use, the release film is removed to adhere the second adhesive layer 43 to the battery compartment.

[0048] This utility model provides a terminal device, as shown in the following embodiment. Figures 2-4 The terminal device includes a battery compartment 5 and a battery structure. The battery structure is located inside the battery compartment 5. The second connecting piece 4 is bonded to the battery compartment 5. The second external part 42 is spaced apart from the side wall of the battery compartment 5 to provide rotation space for the second external part 42.

[0049] As an example, the terminal device includes a battery compartment 5 and a battery structure. The battery structure includes a battery 1, a first connecting piece 2, an electrolytic adhesive 3, and a second connecting piece 4. The first connecting piece 2 has a first external portion 21 for connecting a power-conducting device. The second connecting piece 4 has a second main body portion 41 and a second external portion 42 rotatably connected to the second main body portion 41. The second external portion 42 protrudes from the first connecting piece 2, bypasses the side of the battery 1, and is detachably connected to the top of the battery 1. The second external portion 42 is used to connect a power-conducting device. When it is necessary to install battery 1, electrolytic adhesive 3 is bonded between the first connecting piece 2 and the second connecting piece 4. Specifically, electrolytic adhesive 3 is bonded between the first connecting piece 2 and the second main body 41 to connect the first connecting piece 2 and the second connecting piece 4 together. The first connecting piece 2 is bonded to the bottom of battery 1, and the electrolytic adhesive 3 is located at the bottom of battery 1. The second main body 41 is used to bond battery compartment 5 and is located at the bottom of the first connecting piece 2. The second external part 42 bypasses the side of battery 1 and is fixed to the top of battery 1 to install battery 1 in battery compartment 5. When battery 1 needs to be removed, the second external part 42 is in a disassembled state from the top of battery 1. After the second external part 42 is rotated to a preset angle relative to the first connecting piece 2 (specifically, all outer edges of the first connecting piece 2), the first external part 21 and the second external part 42 are connected into a conductive circuit to de-adhere the electrolytic adhesive 3. Specifically, an electrical device is used to energize the second connecting piece 4 and the first connecting piece 2, forming a conductive circuit between them. At this time, the electrolytic adhesive 3 between the second connecting piece 4 and the first connecting piece 2 can be electrolyzed and de-adheded in the electric field environment, thus facilitating the removal of battery 1 from battery compartment 5. At the same time, the electrolytic adhesive 3 is melted and leaves no residue in battery compartment 5. This reduces the difficulty of installing and removing battery 1 and improves the efficiency of battery installation and removal. The first connecting piece 2 and the second connecting piece 4 are both metal films, such as aluminum films.

[0050] In this example, when the battery 1 is removed, the second external part 42 is in a disassembled state from the top of the battery 1. The second external part 42 is rotated to a preset angle relative to all the outer edges of the first connecting piece 2. This creates a gap between the second external part 42 and all the outer edges of the first connecting piece 2, thus separating the second external part 42 from all the outer edges of the first connecting piece 2. This ensures that the second connecting piece 4 will not come into contact with the first connecting piece 2 and short-circuit, effectively solving the risk of short circuit.

[0051] The second external part 42 is spaced apart from the side wall of the battery compartment 5 to provide rotation space for the second external part 42. This makes it easier to pull the second external part 42 when removing the battery 1. During the removal of the battery 1, the second external part 42 is pulled out of a non-right-angle path. There is an angle between the surface of the extension part 22 away from the battery 1 and the second external part 42. That is, the second external part 42 rotates to a preset angle relative to all the outer edges of the first connecting piece 2. This creates a gap between the second external part 42 and all the outer edges of the first connecting piece 2, realizing the separation of the second external part 42 from all the outer edges of the first connecting piece 2. This ensures that the second connecting piece 4 will not come into contact with the first connecting piece 2 and short-circuit, effectively solving the short-circuit risk.

[0052] In one embodiment, the battery compartment 5 is an insulated battery compartment.

[0053] As an example, battery compartment 5 is an insulated battery compartment, which can reduce the weight and cost of the terminal device, and effectively isolate battery 1 from external metal parts or conductive environments, avoiding short circuit faults caused by damage to battery compartment 5, improper installation, or intrusion of external conductive substances. The arc resistance of the insulated battery compartment can prevent the spread of arcs and prevent fire or explosion accidents. The insulated battery compartment can reduce the parasitic capacitance and inductance between battery 1 and the external environment, reducing signal interference and energy loss. The insulating material usually has low thermal conductivity, which can reduce heat exchange between battery 1 and the external environment and prevent local overheating or overcooling. The insulating material (such as polycarbonate, polyamide) has excellent chemical corrosion resistance, which can resist the corrosion of leaked electrolyte from battery 1, salt spray or moisture in the environment, and extend the service life of the battery compartment.

[0054] The above-described embodiments are only used to illustrate the technical solutions of this application, and are not intended to limit them. Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this application, and should all be included within the protection scope of this application.
