Description

Technical Field

[0001] This utility model relates to the field of new energy battery box technology, and in particular to a highly stable new energy battery box. Background Technology

[0002] With the rapid development of the new energy vehicle industry, the safety and reliability of power batteries, as their core energy source, are of paramount importance. The battery housing is a fundamental structural component that houses and protects key parts such as battery modules and battery management systems. Its performance directly affects the safety, lifespan, and operational stability of the entire vehicle; therefore, a high-temperature solid-state new energy battery housing is needed.

[0003] The battery boxes commonly found in existing new energy vehicles have relatively simple structural designs, relying mainly on the thickness of the sheet metal itself to ensure strength. During vehicle operation, especially on rough roads, during sharp turns, or when subjected to unexpected impacts, the box is prone to deformation, twisting, or even cracking. This deformation can not only directly damage the internal battery modules, leading to short circuits, leakage, or even thermal runaway risks, but also cause the battery cells to expand and bulge after prolonged use. Since users cannot understand the condition of the battery cells inside the battery box, there are potential safety hazards. Utility Model Content

The limiting plate is bolted to the bottom of the inside of the battery box housing. The side guards are bolted to the inner wall of the battery box housing. The protective top plate is bolted to the top of the limiting plate and the side guards. The battery cell structure is disposed inside the battery box housing.

[0009] Furthermore, the limiting plate and the side guard have a U-shaped cross-section, and the battery cell structure is located between the limiting plate, the side guard, and the protective top plate.

[0010] Furthermore, the cell structure includes an inner shell, multiple sets of partitions, a cell body, multiple sets of connecting pieces, and a top protector. The inner shell is located between the side protectors and the limiting plate. The multiple sets of partitions are evenly distributed and welded to the inner wall of the inner shell. The cell body is located between the partitions. The multiple sets of connecting pieces are bolted to the top of the cell body. The top protector is located on the top of the cell body.

[0011] Furthermore, the inner shell has an opening at the top, the top protector is connected to the limiting plate by bolts, and the top protector is attached to the protective top plate.

[0012] Furthermore, a connecting column is bolted to the side wall of the side guard, a fixing cylinder is sleeved on the outside of the end of the connecting column, a protective spring is installed on the inner wall of the fixing cylinder, and a contact sensor is installed on the end of the protective spring.

Detailed Implementation

[0023] To more clearly and completely illustrate the technical solution of this utility model, the following description, in conjunction with the accompanying drawings, will further explain this utility model.

[0024] Please refer to Figures 1-5 This utility model proposes a highly stable new energy battery box, including a battery box cover 1. The top of the battery box cover 1 is provided with an opening for the initial protection of the battery cell body 13. A wiring port 2 is installed through the side wall of the battery box cover 1 for connecting the battery box to an external line. A protective component is provided inside the battery box cover 1 to protect the battery cell body 13. Mounting plates 3 are symmetrically installed on both side walls of the battery box cover 1 by bolts. A handle 4 is rotatably installed on the side wall of the mounting plate 3 to facilitate the user to lift and move the battery box.

[0025] The protective assembly includes a circuit board 5, a protective top cover 6, a limiting plate 7, multiple sets of side guards 8, a protective top plate 9, and a battery cell structure 10. The circuit board 5 is bolted inside the battery box housing 1. The protective top cover 6 is bolted to the outside of the top of the battery box housing 1 to seal the top of the battery box housing 1. The limiting plate 7 is bolted to the bottom inside the battery box housing 1. The side guards 8 are bolted to the inner wall of the battery box housing 1. There is a cavity between the side guards 8 and the battery box housing 1 to buffer the deformation of the battery box housing 1. To prevent direct damage to the battery cell body 13, a protective top plate 9 is bolted to the top of the limiting plate 7 and the side guard 8. A battery cell structure 10 is provided inside the battery box cover 1. The limiting plate 7 and the side guard 8 have a U-shaped cross-section. The battery cell structure 10 is located between the limiting plate 7, the side guard 8 and the protective top plate 9. With the side guard 8, the limiting plate 7 and the protective top plate 9, the battery cell body 13 can be protected, preventing the impact force from acting directly on the battery cell body 13 when the battery box cover 1 is impacted, thus achieving stable protection for the battery cell body 13.

[0026] The battery cell structure 10 includes an inner shell 11, multiple sets of partitions 12, a battery cell body 13, multiple sets of connecting pieces 14, and a top protective member 15. The inner shell 11 is located between the side protective member 8 and the limiting plate 7. The multiple sets of partitions 12 are evenly distributed and welded to the inner wall of the inner shell 11. The battery cell body 13 is located between the partitions 12 to avoid contact between the battery cell bodies 13. The multiple sets of connecting pieces 14 are bolted to the top of the battery cell body 13 for connecting the connecting wires. The top protective member 15 is located on the top of the battery cell body 13. The top of the inner shell 11 is open. The top protective member 15 is bolted to the limiting plate 7. The top protective member 15 is attached to the protective top plate 9. With the top protective member 15, the inner shell 11, and the partitions 12, the battery cell body 13 can be protected.

[0027] The side guard 8 has a connecting post 16 bolted to its side wall. A fixing cylinder 17 is sleeved on the outside of the end of the connecting post 16. A protective spring 19 is installed on the inner wall of the fixing cylinder 17 to protect the contact sensor 18. The contact sensor 18 is installed at the end of the protective spring 19. The connecting post 16 and the fixing cylinder 17 are slidably arranged. The contact sensor 18 is connected to the circuit board 5. The fixing cylinder 17 is fixedly connected to the inner wall of the battery box cover 1. When the battery cell body 13 expands or the battery box cover 1 is deformed by impact, the end of the connecting post 16 contacts the contact sensor 18. The contact sensor 18 transmits a signal to the circuit board 5, and the circuit board 5 issues an alarm to remind the user that the battery box cover 1 or the battery cell body 13 is damaged.

[0028] Of course, there may be other implementations of this utility model. Based on this implementation, other implementations obtained by those skilled in the art without any creative effort are all within the scope of protection of this utility model.
