Description

Technical Field

[0001] This application relates to the technical field of lithium batteries, and in particular to a battery box for a lithium battery energy storage system. Background Technology

[0002] Lithium-ion batteries are a type of battery that uses lithium metal or lithium alloys as the positive / negative electrode materials and a non-aqueous electrolyte solution. The earliest lithium metal battery was proposed and studied by Gilbert N. Lewis in 1912. In the 1970s, MS Whittingham proposed and began researching lithium-ion batteries. Due to the highly reactive chemical properties of lithium metal, its processing, storage, and use require very strict environmental controls. With the development of science and technology, lithium-ion batteries have become the mainstream technology.

[0003] A search revealed Chinese Patent Publication No. CN218274858U, which discloses a vibration-damping and stable lithium battery box, comprising a battery box cover, an inner battery box, and an outer battery box. A second permanent magnet is snapped and fixed around the inner perimeter of the outer battery box. The inner battery box is welded and fixed to the inner side of the outer battery box. A first permanent magnet is snapped and fixed around the outer perimeter of the inner battery box. The battery box cover is snapped and fixed to the top of the outer battery box, and a cable management box is welded and fixed to the bottom of the battery box cover. This invention solves the problems of existing lithium battery boxes, such as difficulty in stably managing the connecting wires during installation, potential entanglement or displacement of the connecting wires due to vibration after prolonged use, difficulty in disassembling and repairing the lithium battery box, and potential weakening of the spring force after prolonged use, leading to a decrease in shock absorption.

[0004] Regarding the aforementioned related technologies, the inventors have discovered the following defects: the prior art lacks a clamping mechanism, making it inconvenient to install batteries of different sizes. In order to solve the problem in the prior art, this application sets up components such as a bottom plate and a top plate, so that the distance between the first clamp and the second clamp can be adjusted, thereby achieving the effect of clamping and fixing batteries of different sizes.

[0032] Please see Figure 2 , 3 7. A support plate 14 is fixedly connected to the upper surface of the top plate 3. The interior of the support plate 14 is rotatably connected to the outer surface of the second drive rod 9. Two support rods 15 are rotatably connected to both ends of the support plate 14.

[0033] Please see Figure 2 , 5 6. Each slider 16 has a support bar 17 rotatably connected to both ends. The top of each support bar 17 is rotatably connected to the base plate 2.

The first drive rod 6 is rotated, which drives two first drive members 5 to slide. The second drive rod 9 is rotated, which drives two second drive members 8 to slide, so that the two first clips 4 and the second clips 7 are in contact with the outer surface of the battery, thereby achieving clamping and fixing of the battery. When the battery box body 1 is vibrated, the bottom plate 2 moves up and down. The bottom plate 2 drives the slide bar 16 to slide through the support bar 17. When the slide bars 16 are close to each other, the damping rod 21 contracts and the second spring 22 is compressed. When the slide bars 16 are far apart, the damping rod 21 extends and the first spring 20 is compressed, thereby achieving shock absorption of the bottom plate 2.

[0038] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
