Description

Technical Field

[0001] The utility model relates to the technical field of automobile parts, in particular to a storage battery box cover and a storage battery box for commercial vehicles. Background Technique

[0002] The storage battery box has good sealing performance to prevent battery liquid leakage and maintain the stability of the internal environment of the battery. In order to ensure that the battery pack does not undergo large deformation during a collision, the storage battery box material is usually selected as a metal material with high strength and high stiffness. The storage battery box cover of a commercial vehicle is an important component for protecting the storage battery. It can prevent dust, moisture, and other sundries from entering the storage battery box, thereby protecting the storage battery from damage and extending its service life.

[0003] For the existing storage battery box cover (such as the publication number CN207353305U), in order to reduce the overall mass and use cost of the storage battery box, the cover body is set as a hollow plastic structure, and metal support rods arranged horizontally and vertically and flame retardant particles are fixedly arranged inside the hollow plastic cover body. By the combined use of plastic and metal support rods, while reducing the overall mass of the storage battery box cover, the anti-deformation ability of the upper cover is ensured.

[0004] For the current storage battery box cover with plastic-coated metal support rods, limited by the overall structure of the box cover, the anti-trampling ability of the box cover is limited. When trampling occurs, the trampling force directly acts on the box cover, and the box cover is extremely easy to be damaged by trampling, resulting in the sealing failure of the box cover, and the whole box cover needs to be replaced. Moreover, the metal support rods of the box cover are arranged inside the box cover, with a complex overall structure, difficult manufacturing and high manufacturing cost, which greatly increases the use and maintenance cost of the box cover.
