Description

Technical Field

[0001] The utility model relates to the technical field of battery boxes, in particular to a battery box for new energy vehicles. Background Art

[0002] With the rapid development of the new energy vehicle industry, batteries, as its core components, are receiving increasing attention for their safety and durability. As a key component for protecting batteries, the battery box is often equipped with a protective plate at the bottom, which is designed to resist the impact of external objects such as stones and hard objects on the road during driving, thereby protecting the battery from damage. For example, China's authorized utility model patent (Announcement No.: CN220021391U) discloses a new energy vehicle battery box. Through the provision of a protective armor plate, the battery can be effectively protected when it is hit by hard objects during road driving, avoiding damage to the battery box and causing the battery to be exposed, thereby forming protection for the battery box body. However, the battery box protective plates currently widely used on the market are the same as the protective armor plates, and most of them adopt a single-layer metal plate structure. Although this design provides the necessary protection function to a certain extent, it has certain limitations for long-term use;

[0003] Specifically, after experiencing long-term and frequent impacts, especially under complex and changeable road conditions, a single-layer metal protective plate will often suffer severe wear, dents or even cracks in local areas, resulting in a significant decrease in protective effectiveness. Once the protective plate is severely damaged, the entire protective plate needs to be replaced to restore its protective performance. This traditional replacement method is costly because even local damage often requires replacing the entire protective plate, resulting in a waste of resources and unnecessary economic burden. Therefore, a battery box for new energy vehicles is proposed to address the above situation. Utility Model Content

[0004] The purpose of this utility model is to provide a battery box for new energy vehicles. Through the structural design of the assembly groove, lower plate, support rod and upper plate, a double-layer protective structure is formed, which extends the overall replacement cycle, reduces the maintenance and replacement costs, and solves the problem of high replacement cost.

[0005] The utility model is realized through the following technical solutions:

[0006] The utility model is a battery box for new energy vehicles, comprising a battery box body, a protective plate and bolts. An assembly groove is provided at the bottom of the battery box body, a row of openings are provided on both sides of the outer wall of the battery box body, and the two rows of openings are connected to the assembly groove. Bumps are provided on both sides of the outer wall of the battery box body, and both rows of bumps have perforations.

[0007] The protective plate includes a lower plate body, a row of support rods is provided on the top of the lower plate body, an upper plate body is provided on the top of the row of support rods, a buffer cavity is provided between the lower plate body and the upper plate body, and connecting blocks are provided at both ends of the row of support rods. The connecting blocks extend out of the buffer cavity and have assembly holes on the connecting blocks.

[0008] When the upper plate body is matched in the assembly groove, the connecting block is matched with the opening, and the bolt is matched in the through hole and the assembly hole.

[0009] Furthermore, a battery placement compartment is provided on the top of the battery box body, and a transverse reinforcing rib and four longitudinal reinforcing ribs are provided in the battery placement compartment.

[0010] Furthermore, the transverse reinforcing ribs and the four longitudinal reinforcing ribs divide the battery placement slot into multiple placement slots, and the transverse reinforcing ribs and the four longitudinal reinforcing ribs are made of the same material as the battery box body.

[0011] Furthermore, when the connecting block is fitted into the opening, the bottom of the protrusion fits the connecting block, and the through hole and the assembly hole are cocentric.

[0012] Furthermore, rubber pads are provided on the top and bottom of the support rod.

[0013] The utility model has the following beneficial effects:

[0014] The utility model forms a double-layer protection structure through the structural design of the assembly groove, the lower plate, the support rod and the upper plate. When the lower plate is seriously damaged due to long-term impact by road stones or hard objects, the protective plate is turned over as a whole and assembled, and the upper plate can continue to play a protective role, effectively extending the overall replacement cycle, reducing the number and frequency of replacement parts, and reducing maintenance and replacement costs.

[0015] The utility model adopts the structural design of the lower plate, the support rod and the upper plate, so that a buffer cavity is provided between the lower plate and the upper plate. The existence of the buffer cavity not only serves as a buffer space, but also can absorb part of the impact energy when the lower plate is bumped and dented, preventing the impact from being directly transmitted to the upper plate, further protecting the integrity of the upper plate, and ensuring that the upper plate can continue to complete the protection work subsequently, thereby enhancing the overall protection capability of the battery box.

[0016] Of course, any product implementing the present invention does not necessarily need to achieve all of the advantages described above at the same time. BRIEF DESCRIPTION OF THE DRAWINGS
