[0030] With the continuous development of the economy, mobile terminals such as tablets and laptops have gradually entered thousands of households and are being used more and more widely. Some of these mobile terminals use a detachable battery structure. These detachable batteries are generally fixed with spring buckles. The advantage of this spring buckle structure is that it is convenient and easy to disassemble and assemble. However, the lack of guidance makes it difficult to install the battery into the device after long-term use. The spring buckle needs to be pushed to install the battery, which affects the convenience of battery installation.

[0031] To solve the above problems, please refer to Figure 1 and Figure 2 The present invention proposes a battery fixing structure 1000, including a shell 1, a first buckling part 2 and a second buckling part 3. The shell 1 forms a mounting cavity with an opening; the first buckling part 2 is horizontally arranged in the mounting cavity and elastically connected to the inner wall of the mounting cavity; the second buckling part 3 is used to install the battery, and the second buckling part 3 encloses a mounting groove 31. The second buckling part 3 can push the first buckling part 2 and cause it to produce elastic displacement, so that the first buckling part 2 can slide into the mounting groove 31 after being reset, thereby realizing the matching connection between the first buckling part 2 and the second buckling part 3.

[0032] The technical solution of the present invention is to provide a mounting cavity with an opening in the housing 1, and the first snap-fitting part 2 is installed in the mounting cavity along the horizontal direction and can move horizontally in the mounting cavity. When the battery is installed into the mounting cavity, the second snap-fitting part 3 is installed from the opening and the first snap-fitting part 2 is pushed to cause elastic movement so that the first snap-fitting part 2 completely enters the mounting cavity. The first snap-fitting part 2 is reset to be locked in the mounting groove 31 of the second snap-fitting part 3, thereby realizing the snap-fit ​​connection between the first snap-fitting part 2 and the second snap-fitting part 3, which not only ensures the stability of the battery installation but also improves the convenience of battery installation.

[0033] In an optional embodiment, to facilitate the elastic return of the first snap-fitting portion 2, the battery securing structure 1000 further includes an elastic member 4, which is connected to the inner wall of the mounting cavity and to the first snap-fitting portion 2. In actual design, the first snap-fitting portion 2 may be inherently elastic, so that the second snap-fitting portion 3 causes elastic displacement or deformation of the first snap-fitting portion 2, thereby allowing the second snap-fitting portion 3 to continue to enter the mounting cavity. In this embodiment, to extend the service life of the first snap-fitting portion 2 and facilitate the installation and replacement of parts within the mounting cavity, an elastic member 4 is provided to connect the first snap-fitting portion 2, allowing it to elastically displace within the mounting cavity to facilitate the installation of the second snap-fitting portion 3. This prevents fatigue caused by repeated deformation of the first snap-fitting portion 2, thereby extending the service life of the first snap-fitting portion 2. Furthermore, by providing a separate elastic member 4, even if the elastic member 4 becomes fatigued due to repeated use and its effectiveness is affected, the battery securing structure 1000 can be maintained by simply replacing the elastic member 4.

[0034] Optionally, the elastic member 4 can be one of a spring, a spring sheet, and an elastic rubber block provided on the inner wall of the installation cavity, and it is only necessary to ensure that the first buckle portion 2 has space for elastic displacement. In this embodiment, the elastic member 4 is a spring extending along the movement direction of the first buckle portion 2. When the second buckle portion 3 is installed into the installation cavity from the open position, the second buckle portion 3 pushes the first buckle portion 2 to squeeze the spring so that it compresses and accumulates elastic potential energy. At the same time, the first buckle portion 2 moves so that the second buckle portion 3 can continue to enter the installation cavity. When the second buckle portion 3 continues to enter the installation cavity for a certain distance, the second buckle portion 3 no longer applies a force to the first buckle portion 2. At this time, the spring is no longer constrained and releases elastic potential energy to push the first buckle member to reset, thereby pushing the first buckle portion 2 into the installation groove 31 of the second buckle portion 3, realizing the snap-fitting fit between the first buckle portion 2 and the second buckle portion 3, thereby completing the installation of the battery. Optionally, in order to ensure the stability of the spring during elastic deformation and avoid large radial deviation of the spring, a guide column can be provided inside the spring to limit the spring and ensure the stability of the spring deformation.

[0035] In an optional embodiment, in order to facilitate the insertion of the first fastening portion 2 into the installation groove 31 of the second fastening portion 3 to achieve battery installation, the second fastening portion 3 is formed with a hook structure at the notch position of the installation groove 31, and the hook structure is formed with a first guide surface 21. The first fastening portion 2 is formed with a first abutting surface 32, and the first guide surface 21 abuts against the first abutting surface 32, so that the first fastening portion 2 slides along the first guide surface 21 into the installation groove 31. Please refer to Figure 1The barb is provided at the notch position of the mounting groove 31 of the second buckling part 3, and the barb structure is formed with a first guide surface 21, which abuts against the first guide surface 21 through the first abutting surface 32, so that the first buckling part 2 can slide into the mounting groove 31 along the first guide surface 21. Optionally, the first guide surface 21 is an inclined surface, so that when installing the second buckling part 3, the first guide surface 21 can apply a horizontal thrust to the first buckling part 2 by simply pressing down the second buckling part 3, so as to push the first buckling part 2 to move. In this way, the installation of the first buckling part 2 is more labor-saving and convenient, and the difficulty of installing the second buckling part 3 can be changed by adjusting the inclination of the inclined surface. In this embodiment, the barb structure is formed by bending a piece of structure, which can not only facilitate the molding and manufacturing of the second buckling part 3, but also reduce the mass of the second buckling part 3. In other embodiments, the barb structure may also be a solid structure with a triangular or trapezoidal cross-section, which can improve the strength of the barb structure. The specific selection can be made according to actual needs and is not specifically limited here.

[0036] Furthermore, in order to facilitate the removal of the battery from the installation cavity, the second fastening portion 3 further includes a second guide surface 22, which is located on the side wall of the installation groove 31 and is provided on the side of the first fastening portion 2 away from the first abutting surface 32. The first fastening portion 2 further includes a second abutting surface 33, the first abutting surface 32 and the second abutting surface 33 are arranged opposite to each other, and the second abutting surface 33 abuts against the second guide surface 22, so that the first fastening portion 2 can slide out of the installation groove 31 along the second guide surface 22. Please refer to Figure 2 When the second fastening portion 3 needs to be removed from the mounting cavity, the spring is compressed by pushing the spring catch, thereby disengaging the first fastening portion 2 from the mounting groove 31 of the second fastening portion 3. The second abutting surface 33 of the first fastening portion 2 engages with the second guide surface 22 of the second fastening portion 3, allowing the second fastening portion 3 to slide along the second guide surface 22 during its upward movement and disengage from the mounting cavity, thereby achieving the purpose of removing the second fastening portion 3 and removing the battery. In addition, in this embodiment, the height of the first guide surface 21 is higher than the second guide surface 22. Therefore, when removing the second fastening portion 3, after the second fastening portion 3 moves upward and disengages the second abutting surface 33 from the second guide surface 22, the spring is still in a compressed state. After the spring is freed from restraint, its elastic potential energy is released to push the first fastening portion 2 to the left, causing the first abutting surface 32 to contact the first guide surface 21. In this way, the second fastening portion 3 is pushed upward by the released elastic potential energy, making the battery removal process convenient and labor-saving.

[0037] In addition, in the actual design process, the first abutting surface 32 and the second abutting surface 33 on the first buckling part 2 can be a plane or an arc surface, so that the installation and disassembly of the battery can be realized. In this embodiment, in order to improve the stability of the battery during assembly and disassembly, the first abutting surface 32 and the second abutting surface 33 are set to be planes. This is because the second buckling part 3 is set above the first buckling part 2. During the assembly and disassembly process, the second buckling part 3 will produce a certain degree of obstruction to the battery fixing structure 1000, which is inconvenient for the operator to operate. The first abutting surface 32 and the second abutting surface 33 are both set to be planes, so that the first buckling part 2 and the second buckling part 3 maintain planar contact during the assembly and disassembly process. In this way, the second buckling part 3 can be restricted by the first abutting surface 32 and the second abutting surface 33 during the assembly and disassembly process, and always maintain a relatively stable state, thereby ensuring the stability of the battery during assembly and disassembly.

[0038] In an optional embodiment, in order to ensure the stability of the connection between the first buckling part 2 and the second buckling part 3, the number of the first buckling part 2 and the second buckling part 3 is at least two, and each first buckling part 2 and each second buckling part are arranged at intervals along the horizontal direction, and a first buckling part 2 is clamped in the installation groove 31 of a second buckling part 3. Please refer to Figure 1 and Figure 2 The two first snap-fitting portions 2 are spaced apart and connected, achieving synchronized movement via a spring latch. The two second snap-fitting portions 3 are also spaced apart horizontally, allowing one first snap-fitting portion 2 to snap onto another second snap-fitting portion 3, ensuring the stability of the battery securing structure 1000. This ensures that even if one of the first snap-fitting portions 2 / second snap-fitting portions 3 is damaged, the other first snap-fitting portion 2 / second snap-fitting portion 3 will continue to maintain a stable connection within the battery securing structure 1000, thereby ensuring stable battery installation. In other embodiments, the number of first snap-fitting portions 2 and second snap-fitting portions 3 may be three or more, and this is not specifically limited here. In this embodiment, to facilitate the molding of the second snap-fitting portions 3, the second snap-fitting portions 3 are integrally formed by bending a sheet-like structure, with each second snap-fitting portion 3 connected end to end, forming a one-piece design. This facilitates installation of the second snap-fitting portions 3 and allows for battery removal with a single operation. Optionally, the first snap-fitting portions 2 and second snap-fitting portions 3 may be made of plastic or metal, such as copper, aluminum, or stainless steel, depending on actual needs.

[0039] The present utility model also proposes a mobile terminal, which includes a battery fixing structure 1000. The specific structure of the battery fixing structure 1000 refers to the above-mentioned embodiment. Since the mobile terminal adopts all the technical solutions of all the above-mentioned embodiments, it has at least all the beneficial effects brought by the technical solutions of the above-mentioned embodiments, which will not be repeated here.
