[0002] Lithium battery testing is a process of systematically evaluating the performance, safety, lifespan, and compliance of lithium batteries, aiming to comprehensively ensure battery quality.
[0003] Lithium battery drop test platforms are mainly used to simulate the drop impacts that batteries may encounter during transportation, loading and unloading, etc., in order to evaluate their safety performance and packaging protection effect. The test platform verifies the battery packaging's impact protection effect by simulating free fall from a height of 1.0-1.5 meters. If the battery fails the test, problems such as shell cracking and internal structural damage may occur, leading to safety hazards such as short circuits and fires. However, when using existing drop test platforms, the drop test chamber and drop machine are fixed together. The test chamber is easily damaged by long-term impacts from lithium battery drops, and the replacement cost is relatively high. Utility Model Content

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.
[0025] Please see Figure 1-5 One embodiment provided by this utility model:
[0026] A lithium battery drop test platform, comprising:
[0027] The enclosure includes a drop test chamber 1, and a drop test machine 11 is provided on the surface of the drop test chamber 1. Both the drop test chamber 1 and the drop test machine 11 are existing products and are not considered as technical protection points of this application. They will not be described in detail here.
[0028] The mechanism facilitates replacement and includes a mounting slot 2, which is formed on the surface of the drop test chamber 1 for mounting a mounting block 21. The mounting block 21 is fixedly connected to the surface of the drop test chamber 11 for insertion into the mounting slot 2. A limiting groove 22 is fixedly connected to the surface of the drop test chamber 1 for connecting a rod 24. A handle 23 is movably connected to the surface of the limiting groove 22 for moving the rod 24. The rod 24 is fixedly connected to the surface of the handle 23 for insertion into the mounting block 21. A limiting block 25 is fixedly connected to the surface of the rod 24 for limiting the movement of the rod 24. A damping spring 26 is wound around the surface of the rod 24 for insertion into the mounting block 21 through its own deformation.
[0029] Furthermore, the mounting block 21 is connected to the surface of the drop test chamber 1 by the mounting groove 2, and the drop machine 11 is connected to the surface of the drop test chamber 1 by the mounting block 21, so that the mounting block 21 is installed into the mounting groove 2.
[0030] Furthermore, the insertion rod 24 is movably connected to the inside of the mounting groove 2 via the pull handle 23, and the limiting block 25 is movably connected to the inside of the limiting groove 22 via the insertion rod 24. Pulling the pull handle 23 causes the insertion rod 24 to leave the inside of the mounting groove 2, so that the mounting block 21 can be installed into the inside of the mounting groove 2. The limiting block 25 moves inside the limiting groove 22 following the movement of the insertion rod 24, limiting the movement position of the insertion rod 24. The damping spring 26 deforms accordingly.
[0031] Furthermore, the two ends of the damping spring 26 are fixedly connected to the inside of the limiting groove 22 and the surface of the limiting block 25. The limiting block 25 is movably connected to the inside of the limiting groove 22 through the damping spring 26. When the restriction on the pull handle 23 is released, the damping spring 26 drives the limiting block 25 to reset in order to restore its original state.
[0032] Furthermore, a slot is provided on the surface of the mounting block 21, and the rod 24 is connected to the surface of the mounting block 21 by a damping spring 26. The rod 24 is reset and inserted into the slot on the surface of the mounting block 21 as the limiting block 25 moves, thereby fixing the installation position of the mounting block 21.
[0033] Furthermore, a convenient plate-changing mechanism includes a connecting block 3, which is fixedly connected to the surface of the drop test chamber 1 for mounting the mounting block 35. A connecting base 31 is fixedly connected to the surface of the connecting block 3 for connecting the limiting buckle 32. A limiting buckle 32 is fixedly connected to the surface of the connecting base 31 for engaging the mounting block 35 through its own deformation. A fixed shaft 33 is fixedly connected to the surface of the drop test chamber 1 for rotating the chamber plate 34. The chamber plate 34 is rotatably connected to the surface of the fixed shaft 33 for opening and facilitating the replacement of the test plate inside the drop test chamber 1. The mounting block 35 is fixedly connected to the surface of the chamber plate 34 for mounting on the surface of the connecting block 3.
[0034] Furthermore, the connecting blocks 3 are symmetrically distributed in two sets on the surface of the drop test chamber 1, and the mounting blocks 35 are symmetrically distributed in two sets on the surface of the box plate 34. The two sets of connecting blocks 3 are used to install the two sets of mounting blocks 35. The box plate 34 is rotatably connected to the surface of the drop test chamber 1 through the fixed shaft 33. The mounting blocks 35 are abutted and connected through the surface of the box plate 34 and the connecting blocks 3. Rotating the box plate 34 can open the box plate 34 to facilitate the replacement of the test plate inside the drop test chamber 1. After replacement, the box plate 34 is closed so that the mounting blocks 35 are installed on the surface of the connecting blocks 3.
[0035] Furthermore, the mounting block 35 is connected to the surface of the box plate 34 and the connecting base 31 by interlocking. The limiting buckles 32 are evenly distributed in four groups on the surface of the connecting base 31. The mounting block 35 is connected to the surface of the connecting block 3 by interlocking with the limiting buckles 32. The mounting block 35 is inserted into the surface of the connecting base 31. The limiting buckles 32 deform and engage the mounting position of the mounting block 35, thereby fixing the closed position of the box plate 34.
[0036] Working principle: When using the drop test chamber 1, first pull the handle 23 to move the insertion rod 24 away from the inside of the mounting slot 2, so that the mounting block 21 can be installed into the mounting slot 2. The limiting block 25 moves inside the limiting groove 22 following the movement of the insertion rod 24, limiting the movement position of the insertion rod 24. The damping spring 26 deforms accordingly, installing the drop tester 11 on the surface of the drop test chamber 1, so that the mounting block 21 is installed into the mounting slot 2. Release the restriction on the handle 23, and the damping spring 26 returns to its original shape. When the limit block 25 is reset, the insertion rod 24 follows the movement of the limit block 25 and is reset to be inserted into the slot on the surface of the mounting block 21, thereby fixing the installation position of the mounting block 21. Rotating the box plate 34 can open the box plate 34 to facilitate the replacement of the test plate inside the drop test chamber 1. After replacement, the box plate 34 is closed, so that the mounting block 35 is installed on the surface of the connecting block 3. The mounting block 35 is inserted into the surface of the connecting base 31. The limit buckle 32 deforms and engages the installation position of the mounting block 35, thereby fixing the closed position of the box plate 34.
