Description

Technical Field

[0001] This utility model belongs to the field of battery pack technology, specifically relating to a battery pack. Background Technology

[0002] With the rapid development of electric vehicles and energy storage systems, the safety of battery packs, as the core energy carrier, has become a key focus of technological research. Among these, anti-collision design directly relates to the safety performance of battery packs under extreme conditions such as mechanical impact, compression, or drops, and is a crucial element in preventing thermal runaway, short circuits, and even fires and explosions.

[0003] Traditional battery packs primarily rely on the rigid structure of a metal casing (such as steel plates or aluminum alloys) for protection, using increased material thickness or reinforcing ribs to withstand external impacts. However, this approach suffers from drawbacks such as high weight, high energy consumption, and low energy absorption efficiency, making it difficult to balance lightweight design with safety. For example, in a side collision, stress concentration at the corners of the battery pack can cause casing deformation, which in turn can compress the internal cells and trigger an internal short circuit.

[0025] To enable those skilled in the art to better understand the technical solutions of this utility model, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort should fall within the protection scope of this utility model.

[0026] like Figures 1 to 5 As shown, a battery pack according to one embodiment of the present invention includes a battery pack body 11. A base 21 is provided at the bottom of the battery pack body 11. A plurality of protective plates 22 that match the side edges of the battery pack body 11 are fixedly connected to the base 21. An elastic protective pad 23 is fixedly connected to one end face of the protective plate 22 near the battery pack body 11. There is a gap between the protective pad 23 and the battery pack body 11.

[0027] Specifically, during battery pack use, the protective plates 22 located around the battery pack body 11 and matching the side corners provide protection for the side corners of the battery pack body 11, preventing impact to these areas. The corners are stress concentration points on the battery pack casing, making them vulnerable to side impacts, scrapes, or drops. Impacts to these corners can lead to structural deformation, seal failure, and short circuit risks.

[0028] The protective pad 23 is a rubber pad. The rubber pad is elastic. When the protective plate 22 is subjected to a large impact, it may bend inward and hit the battery pack body 11. The protective pad 23 can play a buffering role when the protective plate 22 bends inward and hits the battery pack body 11, so as to avoid damage to the battery pack body 11.

[0029] The protective plate 22 is integrally molded using a bending process, saving costs. Both the protective plate 22 and the base 21 are made of plastic, making them lightweight and less likely to affect the overall weight of the battery pack body 11, thus preventing increased power consumption. The battery pack body 11 is bonded to the base 21, and the protective plate 22 is also bonded to the base 21. Liquid sealant such as polyurethane adhesive can be used, providing shock resistance.

[0030] Furthermore, during the storage and transportation of battery packs, the moisture-proof cloth 12 is an effective moisture-proof protective material, mainly used to absorb ambient moisture and prevent the battery from getting damp, oxidizing, or the electrolyte from deteriorating.

[0031] Generally, the moisture-proof cloth 12 is wrapped around the battery pack to achieve a seal against moisture. The moisture-proof cloth 12 comes in various shapes. When the moisture-proof cloth 12 is flat, it needs to be repeatedly wrapped around the battery pack. When the moisture-proof cloth 12 is shaped like a bag or cover, the opening also needs to be sealed. Then, it is fixed with a fixing strap or rope. The operation is more cumbersome and increases the amount of moisture-proof cloth used.

[0032] Specifically, when wrapping the moisture-proof cloth 12 around the battery pack body 11, if the moisture-proof cloth 12 is in the shape of a bag or cover, it can be directly put on the battery pack body 11. The opening of the moisture-proof cloth 12 is located in the gap between the protective pad 23 and the battery pack body 11. The moisture-proof cloth 12 is pulled down continuously until the moisture-proof cloth 12 completely covers the battery pack body 11.

[0033] The protective pad 23 can abut against the moisture-proof cloth 12, fixing the moisture-proof cloth 12 to the battery pack body 11, so that the moisture-proof cloth 12 is in close contact with the battery pack body 11. The moisture-proof cloth 12 and the base 21 seal the battery pack body 11, making it difficult for the battery pack body 11 to come into contact with the outside air, thus increasing the moisture-proof effect.

[0034] If the moisture-proof cloth 12 is flat, the perimeter of the moisture-proof cloth 12 is located in the gap between the protective pad 23 and the battery pack body 11. Pull the moisture-proof cloth 12 down until the moisture-proof cloth 12 completely covers the battery pack body 11.

[0035] The protective pad 23 can abut against the moisture-proof cloth 12, fixing the moisture-proof cloth 12 to the battery pack body 11, so that the moisture-proof cloth 12 is in close contact with the battery pack body 11. The moisture-proof cloth 12 and the base 21 seal the battery pack body 11, making it difficult for the battery pack body 11 to come into contact with the outside air, thus increasing the moisture-proof effect.

[0036] It can adapt to different shapes of moisture-proof cloth 12, and fix the moisture-proof cloth 12 during the process of wrapping the battery pack body 11, without the need to fix it with fixing ropes or fixing straps after wrapping.

[0037] The protective plate 22 has two parallel surfaces with the battery pack body 11, that is, the protective plate 22 has two fixed surfaces. The moisture-proof cloth 12 can be fixed from two different directions by the protective pad 23, which increases the stability of the moisture-proof cloth 12.

[0038] The base 21 has a storage slot 24, and the moisture-proof cloth 12 at the end can be fixed in the storage slot 24, which can increase the sealing effect of the battery pack body 11 and thus increase the moisture-proof effect.

[0039] A scraper 32 is slidably connected between adjacent protective plates 22. A limiting plate 31 matching the scraper 32 is fixedly connected to the base 21. A buffer part 36 is provided on the limiting plate 31. A first threaded hole 33 is provided on the limiting plate 31. A second threaded hole 34 matching the first threaded hole 33 is provided in the scraper 32. A locking bolt 35 is threadedly connected between the first threaded hole 33 and the second threaded hole 34.

[0040] Specifically, the scraper 32 can slide between a set of protective plates 22. The scraper 32 can abut against the moisture-proof cloth 12. Sliding the scraper 32 downward can smooth and flatten the perimeter of the moisture-proof cloth 12, so that there is no gap between the moisture-proof cloth 12 and the battery pack body 11, so that the moisture-proof cloth 12 fits tightly against the battery pack body 11, increasing the sealing effect and thus increasing the moisture-proof effect.

[0041] The scraper 32 can slide between the limiting plate 31 and the moisture-proof cloth 12. The limiting plate 31 is an elastic block that can squeeze the scraper 32. The scraper 32 squeezes the moisture-proof cloth 12, fixing the bottom of the moisture-proof cloth 12 and preventing it from loosening and falling off. The buffer part 36 allows the scraper 32 to move easily to the inside of the limiting plate 31. The locking bolt 35 fixes the scraper 32 to the limiting plate 31, increasing stability.

[0042] When using, refer to Figures 1-5 As shown, the protective plates 22 that match the edges and corners of the battery pack body 11 are provided around the battery pack body 11 to protect the battery pack body 11. During the transportation or storage of the battery pack, the protective plates 22 can be used to fix the moisture-proof cloth 12 for moisture protection.

[0043] Compared with the prior art, the battery pack of this utility model can protect the edges and corners of the battery pack, has a simple structure, and is easy to operate.
