Description

Technical Field

[0001] The present application relates to the field of communication technology, and in particular to a built-in battery packaging structure, fixing tape and electronic equipment. Background Art

[0002] With the continuous advancement of science and technology and the continuous improvement of people's living standards, user terminal devices such as mobile phones, tablets, and cameras are becoming increasingly common in people's daily lives. To improve the performance of user terminals, consumers and businesses are tending to adopt internal battery solutions. An internal battery refers to a rechargeable battery that is installed within the user terminal through a packaging structure. For manufacturers, the internal battery of a user terminal means that the battery cannot be easily removed; however, any performance anomaly or appearance defect of the user terminal may require battery removal for repair. Therefore, the packaging structure of the internal battery must also take into account the battery's removability.

[0003] Currently, there are two main battery packaging structures inside user terminals: battery bracket fixation and tape fixation.

[0004] The battery holder fixation method involves gluing and securing the battery to the holder, which is then screwed into the battery cavity of the terminal after use. While this method allows for reuse of the battery holder, it requires mold forming during the production process, resulting in high production costs. Furthermore, additional tools are required to remove and install the battery, making it inconvenient for users.

[0005] Tape fixation involves securing the battery directly within the battery cavity using a simple-pull adhesive tape. To remove the battery, simply pull the tape to remove it. Compared to battery bracket fixation, tape fixation is less expensive and requires no additional tools during battery removal. Therefore, it's a popular method for internal battery packaging among consumers and manufacturers, becoming the current mainstream method.

[0006] For battery packaging structures fixed with tape, in order to facilitate pulling the battery, a pulling portion for pulling the battery will be provided on the tape. During the battery removal process, the pulling portion can be pulled away from the battery to achieve battery removal. The following example illustrates this.

[0007] Patent application number 201720645930.1 discloses a built-in battery packaging structure and a lifting tape used to secure the battery within the battery compartment. The lifting tape includes a first region, a second region, and a lifting region. The lifting region is connected to the first region and the second region via a first tear line and a second tear line, respectively. The adhesive portion of the lifting region adheres to the rear shell of the battery, and the lifting portion of the lifting region extends to the front shell of the battery. When the battery needs to be removed, the first and second regions are first pulled up from the front shell of the battery, and then the lifting portion is pulled to remove the battery from the battery compartment.

[0008] However, because the lifting area is connected to the first and second areas via the first and second tear lines, respectively, pulling the lifting portion will pull the first and second areas, requiring increased disassembly force, making disassembly inconvenient and reducing disassembly efficiency. Furthermore, when manufacturing the lifting tape, the first and second tear lines must also be fabricated, increasing the production process and the manufacturing and labor costs of the built-in battery packaging structure.
