Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] The following is combined with Figures 1-5 A detailed description of the sliding rail type quick-release lithium battery module of this utility model is provided below:

[0021] The slide rail 401 type quick-release lithium battery module includes a mounting housing 1 and five lithium battery blocks 2. The mounting housing 1 has a receiving cavity, in which the five lithium battery blocks 2 are installed side-by-side. A partition 3 is provided within the receiving cavity, dividing it into two or more battery mounting slots 4. The inner wall of each battery mounting slot 4 is provided with a slide rail 401 and a contact plate 402. The surface of each lithium battery block 2 is provided with a sliding groove 201 and an electrode post 202. The sliding groove 201 and the slide rail 401 cooperate with each other. The lithium battery block 2 is installed in a single battery mounting slot 4 by matching the slide rail 401 with the slide groove 201. A positioning component is provided between the lithium battery block 2 and the battery mounting slot 4 for engagement. The electrode post 202 and the contact piece 402 are in contact with each other to conduct electricity. An integrated circuit assembly 5 is provided in the receiving cavity. The contact piece 402 is electrically connected to the integrated circuit assembly 5. The integrated circuit assembly 5 is connected to a power supply interface 6 and a charging interface 7. The power supply interface 6 and the charging interface 7 extend to the surface of the mounting housing 1.

[0022] The coordinated design of the slide rail 401 and the positioning component enables quick insertion and removal and reliable fixation of the lithium battery block 2, significantly improving the ease of assembly and disassembly and maintenance efficiency of the battery module. The mating structure of the slide rail 401 and the slide groove 201 allows the battery to be easily pushed in or removed along the guide trajectory, avoiding the cumbersome disassembly process required by traditional bolt fixing. The positioning component ensures a stable connection of the battery after installation, and the contact conductivity between the contact piece 402 and the electrode post 202 further guarantees the continuity and safety of the circuit. This not only facilitates the replacement and upgrading of individual battery blocks but also reduces the maintenance difficulty and operating cost of the overall module, making it suitable for various application scenarios requiring frequent power adjustments or expansions.

[0023] The positioning component includes a slot 203 on the surface of the lithium battery block 2 and a locking block 8 within the battery mounting slot 4. The locking block 8 is movably positioned within the battery mounting slot 4 via an elastic element 9. One end of the locking block 8 extends to the inner wall of the battery mounting slot 4 and engages with the slot 203. An unlocking key 801 is located on the side wall of the locking block 8, extending around the opening of the battery mounting slot 4. Through the combination of elastic engagement and manual unlocking, the dual functions of stable locking and rapid release after battery installation are achieved. The locking block 8 automatically engages with the slot 203 under the action of the elastic element 9, ensuring that the lithium battery block 2 will not accidentally dislodge under vibration or movement, maintaining a reliable connection. The locking state can be easily released by operating the unlocking key 801, making the removal of the battery block simple and quick, further improving the convenience and safety of maintenance operations.

[0024] The side wall of the mounting housing 1 is provided with a sealing cover 10 that covers the battery mounting groove 4. The sealing cover 10 is connected to the mounting housing 1 by bolts. The sealing cover 10 enhances the overall protection capability of the mounting housing 1, effectively preventing dust, moisture and other foreign objects from entering the battery housing cavity, avoiding short circuits or corrosion, and improving the applicability and safety of the module in harsh environments.

The inner wall of the sealing cover 10 is provided with a sealing ring 1001 and a sealing gasket 1002. The mounting housing 1 is provided with a corresponding sealing groove 101. The sealing ring 1001 and the sealing gasket 1002, together with the sealing groove 101, form a multi-seal structure, significantly improving the sealing performance of the mounting housing 1. It has good dustproof, splashproof and moisture-proof effects, extending the service life of the battery module in outdoor or humid environments, while not affecting normal disassembly and assembly operations.

[0025] The opening of the mounting slot is located on the side wall of the mounting housing 1. The sliding groove 201 and the sliding rail 401 are horizontally arranged on the inner wall of the battery mounting slot 4 and the side wall of the lithium battery block 2. The battery block can be horizontally pushed in from the side for installation, which greatly saves installation space and is especially suitable for equipment with limited width or compact layout. The horizontal guiding installation method is more in line with human operating habits, and the installation process is labor-saving and intuitive, which helps to improve assembly efficiency.

[0026] Rollers 11 are provided on the surface of the slide rail 401 and the inner wall of the battery mounting groove 4, with the rollers 11 protruding from the surface of the slide rail 401 and the inner wall of the battery mounting groove 4. The rollers 11 convert sliding friction into rolling friction, which greatly reduces the resistance during the installation and removal of the battery block, making pushing and pulling easier and smoother. This not only reduces the operating force but also avoids wear on the surface of the slide rail 401 and the battery block, which helps to extend the life of components and maintain the flexibility of long-term use.
