[0031] The specific embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are used to illustrate this utility model, but are not intended to limit its scope.

[0032] like Figures 1 to 3 As shown, a preferred embodiment of the present invention provides a battery pack submersion device for lowering the battery pack 4 into the test pit 5. It has a first direction, a second direction and a third direction that are perpendicular to each other, and includes a bracket module 1, a lifting module 2 and a sliding module 3.

[0033] Bracket module 1 is used to support battery pack 4;

[0034] The lifting module 2 is connected to the bracket module 1. The lifting module 2 is used to drive the bracket module 1 to move in the test pit 5 along a third direction.

[0035] The sliding module 3 includes a slider assembly and a slide rail assembly. The slider assembly includes multiple sliding blocks 31 disposed on at least one side of the bracket module 1. The slide rail assembly includes multiple tracks 32 spaced apart along a first direction and / or a second direction. The tracks 32 extend along a third direction and are disposed within the test pit 5, with the tracks 32 corresponding to the sliding blocks 31. Each sliding block 31 is provided with a roller 311, which abuts against the track 32. The axis of the roller 311 disposed on at least one sliding block 31 extends along the first direction, while the axis of the roller 311 disposed on the remaining sliding blocks 31 extends along the second direction. The first direction, the second direction, and the third direction are respectively labeled X, Y, and Z in the accompanying drawings.

[0036] Specifically, when the battery pack 4 experiences risks such as deflagration during testing, it needs to be quickly and stably lowered into the test pit 5. If the battery pack 4 is subjected to tilting or vibration during descent, unpredictable secondary risks can easily occur, affecting the assessment of its condition. In this embodiment, the lifting module 2 drives the bracket module 1 to move up and down along a third direction within the test pit 5. The slider assembly and slide rail assembly restrict the movement of the bracket module 1, preventing deflection and positional shifts during its vertical movement. This avoids affecting the position and state of the battery pack 4 during descent, resulting in a smoother descent. The rollers 311 in the sliding block 31 significantly improve the smoothness and continuity of the bracket module 1's descent, preventing jamming and vibration of the battery pack 4. This further enhances the stability of the battery pack 4's descent, increasing its speed and smoothness, and solving the problem of difficult operation during descent.

[0037] In some embodiments, the bracket module 1 has four sliding blocks 31 spaced apart along the first direction on each of its two sides in the second direction; and eight tracks 32 are provided in the test pit 5 corresponding to the sliding blocks 31.

[0038] In one specific embodiment, the four sliding blocks 31 on one side of the bracket module 1 are arranged opposite to the four sliding blocks 31 on the other side plate of the bracket module 1, thereby ensuring structural balance, further improving the stability of the bracket module 1 and battery pack 4 during descent, and reducing the installation difficulty of the sliding blocks 31 and rails 32. In some other alternative embodiments, the sliding blocks 31 on both sides of the bracket module 1 can also be arranged asymmetrically. Furthermore, in some other embodiments, sliding blocks 31 can be installed on all four sides of the bracket module 1, and correspondingly, multiple rails 32 need to be installed simultaneously on the four inner walls of the test pit 5.

[0039] In some embodiments, the sliding block 31 is provided with a plurality of parallel rollers 311 on each of its two sides in the third direction, and the rollers 311 abut against the inner wall of the track 32. The arrangement of multiple rollers 311 allows for more comprehensive contact with the inner wall of the track 32, thereby making the movement of the sliding block 31 within the track 32 smoother.

[0040] In some embodiments, the axes of the inner rollers 311 of the two sliding blocks 31 located near the two ends of the side of the bracket module 1 are arranged along the second direction; the axes of the inner rollers 311 of the two sliding blocks 31 located at the middle of the side of the bracket module 1 are arranged along the first direction.

[0041] Specifically, in this embodiment, the first roller 3111 within the two sliding blocks 31 located in the middle of the side of the bracket module 1 has its axis facing the first direction, and its roller surface abuts against and rolls relative to the inner bottom surface of the track 32. This stabilizes the position of the bracket module 1 in the second direction, prevents positional changes in the bracket module 1 in the second direction, controls the tilt of the sliding blocks in the second direction, and ensures the stability of the bracket module 1 during descent and prevents vibration. Meanwhile, the second roller 3112 within the sliding blocks 31 located at both ends of the side of the bracket module 1 has its axis facing the second direction, and its roller surface abuts against and rolls relative to the inner surface of the track 32. This stabilizes the position of the bracket module 1 in the first direction, prevents positional changes in the bracket module 1 in the first direction, controls the tilt of the sliding blocks in the first direction, and further ensures the stability of the bracket module 1 during descent.

[0042] In some embodiments, the track includes a first guide plate and a second guide plate, both of which are C-shaped structures; the first guide plate and the second guide plate are fixedly connected, and two cavities are formed between the first guide plate and the second guide plate, which are symmetrically arranged along the axis of the first guide plate; the side of the first guide plate away from the second guide plate faces the bracket module and has a groove, and the roller is disposed in the groove.

[0043] Specifically, during the actual installation process, mounting plates are first pre-embedded in the inner wall of the test pit, corresponding to each track. Then, the fixed first guide rail plate and second fixing plate are fixedly connected to the pre-embedded mounting plates. The first guide rail plate is positioned facing the bracket module from the second guide rail plate, and the opening on the side of the first guide rail plate facing the bracket module forms a groove. Furthermore, the bottom plate of the first guide rail plate fits snugly against the bottom plate of the second guide rail plate, while a cavity is formed between the side plates of the first and second guide rail plates. The side of the bottom plate of the second guide rail plate away from the first guide rail plate is fixedly connected to the pre-embedded mounting plate. This structure provides higher track strength and stronger impact resistance, better coping with impacts from the external environment. The cavity design also effectively provides buffer space, further improving the strength and robustness of the entire track structure, thereby ensuring the stability of the bracket module's vertical movement.

[0044] In some embodiments, the track is provided with a groove 324 with an opening facing the bracket module 1, and a roller is disposed in the groove 324. The groove wall of the groove 324 is provided with a first pin hole 321 and a second pin hole. A first pin 322 is disposed in the first pin hole 321, and a second pin 323 is disposed in the second pin hole. The first pin 322 abuts against the sliding block 31 to limit the sliding block 31 from sliding down.

[0045] The sliding block 31 is provided with a third pin hole 312 corresponding to the first pin hole 321. One end of the first pin 322 is inserted into the first pin hole 321 and the third pin hole 312 in sequence to limit the downward trend of the sliding block 31.

[0046] Specifically, before the actual testing process, staff often need to stand on the bracket to adjust the parameters and position of the battery pack 4. This requires the bracket module 1 to provide stable support for the staff. In one embodiment, by sequentially inserting the first pin 322 into the first pin hole 321 and the third pin hole 312, the downward sliding tendency of the sliding block 31 can be restricted, stabilizing the position of the bracket module 1 and providing a stable working platform for the staff. Furthermore, the second pin 323 can be inserted into the second pin hole on the side of the slide groove, with the sliding block 31 positioned above the second pin 323. The second pin serves as a backup safety measure, providing secondary protection in the event of a breakage of the first pin 322, further preventing the sliding block 31 from sliding down.

[0047] In some embodiments, the lifting module 2 includes an electric hoist 21 and a chain 22. The end of the chain 22 away from the electric hoist 21 is connected to four lifting rings 23. The lifting rings 23 are detachably connected to the bracket module 1. The electric hoist 21 drives the bracket module 1 to move in a third direction through the chain 22.

[0048] Furthermore, the bracket module 1 includes a base plate 11 and a frame 12 that are fixedly connected. The base plate 11 is used to support the battery pack 4, and a sliding block 31 is provided on the side of the base plate 11. Each side of the frame 12 is provided with a plurality of lifting eye holes 121, which are used for threaded connection of lifting eye 23.

[0049] Specifically, during the actual submersion of the battery pack 4, the bottom of the lifting chain 22 has four joints, each connected to a lifting ring 23. These four rings 23 are connected to the four corners of the bracket module 1, providing a more balanced pulling force and making the movement of the bracket module 1 more stable. In a preferred embodiment, the bracket module 1 is equipped with a frame 12, and the lifting ring holes 121 for connecting the lifting rings 23 are also located on the frame 12, not on the base plate 11. The frame 12 provides protection for the battery pack 4. Furthermore, the frame 12 has multiple lifting ring holes 121, allowing the lifting rings 23 to be selectively installed in different holes 121 depending on the weight and position of the battery pack 4. This improves the applicability of the bracket module 1 and the lifting module 2 to different battery packs 4 and enhances the stability of the battery pack 4 during descent.

[0050] In some embodiments, the base plate 11 is provided with at least one access port 111, and the access port 111 is detachably connected to an access cover 112. Specifically, before actual testing, it is often necessary for staff to descend into the test pit 5 to adjust the bottom of the base plate 11 and the battery pack 4. In this embodiment, the detachable access cover 112 allows staff to easily descend from above the base plate 11 into the test pit 5 to adjust the structure of the base plate 11 and the data of the battery pack 4.

[0051] In some embodiments, the frame 12 is equipped with a smoke sensor 122 and a temperature sensor 123, both of which are connected to an alarm light 124. The smoke sensor 122 and the temperature sensor 123 can monitor the status of the battery pack 4 in real time during the test. When the smoke sensor 122 detects smoke emitted by the battery pack 4, or the temperature sensor 123 detects an abnormal temperature of the battery pack 4, it can quickly issue a warning through the alarm light 124, so that the staff can quickly drive the lifting module 2 to lower the battery pack 4 into the test pit 5, thereby ensuring the safety of the battery pack 4 test.

[0052] In summary, this utility model embodiment provides a battery pack 4 submersion device, which can make the descent of the base plate 11 and the battery pack 4 on it more stable and efficient by setting a track 32 in the test pit 5 and setting a sliding block 31 on the base plate 11 corresponding to the track 32. In addition, the roller 311 set in the sliding block 31 can make the descent of the base plate 11 smoother and more continuous, further improving the stability of the base plate 11 during descent and avoiding the adverse effects of vibration on the battery pack 4. The setting of multiple lifting eye holes 121 allows the base plate 11 and the lifting module to be adapted to the descent of more battery packs 4 of different weights, and the applicability is also better.

[0053] The above are merely preferred embodiments of this utility model. It should be noted that, for those skilled in the art, several improvements and substitutions can be made without departing from the technical principles of this utility model, and these improvements and substitutions should also be considered within the protection scope of this utility model.
