Description

Technical Field

[0001] The present invention relates to the technical field of battery pack positioning, and in particular to a positioning device for a marine battery pack. Background Art

[0002] Marine battery packs are energy storage devices designed specifically for ships. Depending on the usage scenarios and performance requirements, marine battery packs can be divided into several types, including lead-acid batteries, nickel-metal hydride batteries, lithium-ion batteries, etc. Among them, lithium-ion batteries have gradually become the mainstream due to their high energy density, long life and environmental protection characteristics.

[0003] Before using the battery pack, it is necessary to position it with a dedicated device or apparatus to prevent the battery pack from slipping or tilting during use, thereby causing damage to the battery pack. At present, most of the marine lithium battery systems follow the land-based system design, and the differences in application scenarios and usage are not considered in the original design of the battery pack. If the special operating conditions of the ship are not considered in the installation of the battery pack, such as the swaying and tilting of the ship during the operation of the ship, the battery pack may be displaced or even fall due to the problem of installing and fixing the battery pack, affecting the use of the battery system. In severe cases, it may cause serious consequences such as power failure of the entire ship. In the prior art, the battery pack is usually fixed to the device only by bolts. However, in a long-term shaking environment, this fixing method may cause the bolts to loosen, which will cause relative movement between the battery pack and the device, which is not conducive to the stable operation of the battery pack.

The block 10 and the moving block 7 move synchronously together, and the moving block 7 moves along the slot 51 into the baffle 5. When the moving block 7 moves a certain distance into the baffle 5, it stops pushing the battery pack body 3. At this time, the threaded hole 6 on the guide rail 2 is aligned with the threaded hole 6 on the battery pack body 3, and they are limited and fixed by bolts. The top of one side of the battery pack body 3 abuts against the bottom of the limiting plate 4, which can ensure that the battery pack will not move in the vertical direction. During the movement of the fixed block 10 and the moving block 7 into the baffle 5, the positioning assembly 8 in the groove 101 will be driven to move into the slot 51 together. When the battery pack body 3 stops moving, the positioning assembly 8 is engaged with the positioning plate 9 in the positioning slot 52, which can ensure that the positioning block 81 and the moving block 7 remain relatively stable, and can better ensure that the battery pack body 3 will not tilt or shake.

At this time, the battery pack body 3 no longer moves, and the positioning rod 83 can be engaged with the positioning plate 9. At this time, the top of the rotating block 16 is aligned with the limiting groove 72. Due to the loss of the squeezing of the moving block 7, the top of the rotating block 16 will be driven to rotate into the limiting groove 72 under the action of the second spring 17, thereby engaging with the limiting groove 72.

The battery pack body 3 slides along the guide rail 2, and the battery pack body 3 drives the fixed block 10 to slide together until the fixed block 10 moves into the transverse groove 71. Then, the battery pack body 3 is continuously pushed to drive the fixed block 10 and the moving block 7 to move synchronously together. The moving block 7 moves toward the inside of the baffle 5 along the notch 51. When the moving block 7 moves a certain distance into the baffle 5, it stops pushing the battery pack body 3.

At this time, the battery pack body 3 no longer moves, and the positioning rod 83 can be engaged with the positioning plate 9. At this time, the top of the rotating block 16 is aligned with the limiting groove 72. Due to the loss of the squeezing of the moving block 7, the top of the rotating block 16 is driven to rotate into the limiting groove 72 under the action of the second spring 17, so as to be engaged with the limiting groove 72, and the moving block 7 and the baffle 5 are also kept in a fixed position.
