Description

Electric pile packaging end plate of hydrogen fuel cell automobile

Technical Field

The utility model relates to the technical field of fuel cell assembly parts, in particular to a galvanic pile packaging end plate of a hydrogen fuel cell automobile.

Background

The fuel cell stack needs to be waterproof and dustproof, and therefore must be packaged. In the packaging structure inner space, the pile is generally fixed on the medial surface of pile encapsulation end plate through pile installing support, pile mounting bolt, but the inside pile installing support of packaging structure often needs occupation space, considers the assembly maintenance moreover, still need reserve sufficient operating space, causes the packaging structure inner space too compact, and is seriously not enough even.

SUMMERY OF THE UTILITY MODEL

The utility model aims to provide a galvanic pile packaging end plate of a hydrogen fuel cell automobile, which aims to solve the existing technical situation, does not need a galvanic pile mounting support, ensures that a galvanic pile and the packaging end plate have enough space, and simultaneously avoids the galvanic pile mounting support from occupying the internal space of a packaging structure.

In order to achieve the purpose, the utility model adopts the following technical scheme:

the utility model provides a galvanic pile encapsulation end plate of hydrogen fuel cell car, is including encapsulation end plate body and shield, the outside of encapsulation end plate body is equipped with the first heavy groove that matches with the shield towards encapsulation end plate body inboard, the bottom surface in first heavy groove is equipped with the second heavy groove to encapsulation end plate body inboard, is equipped with a plurality of boss structures on the medial surface of encapsulation end plate body, and all is equipped with the bolt hole that matches with galvanic pile mounting bolt between the terminal surface in each boss structure and the bottom surface in second heavy groove, the shield is fixed to be set up among the first heavy groove, makes the second heavy groove seal.

Furthermore, a sealing gasket is arranged between the dustproof cover and the bottom surface of the first sinking groove, so that the space in the second sinking groove is a sealing space.

Furthermore, a sealing gasket mounting groove is formed in the bottom surface of the first sinking groove, and the sealing gasket is embedded in the sealing gasket mounting groove.

Furthermore, the dust cover and the first sinking groove are fixedly connected through four groups of dust cover mounting bolts.

Furthermore, four groups of boss structures are arranged on the inner side surface of the packaging end plate body.

The utility model has the beneficial effects that:

compared with the prior art, the galvanic pile packaging end plate of the hydrogen fuel cell automobile can realize direct assembly and connection of the galvanic pile, a galvanic pile mounting support is not needed, sufficient space between the galvanic pile and the packaging end plate is ensured, and meanwhile, the galvanic pile mounting support is prevented from occupying the internal space of the packaging structure; through with the fixed setting of shield among first heavy groove, make the second heavy groove keep sealing down, on the one hand, the shield can quick location assembly, on the other hand, during the dismouting galvanic pile, open the shield can, it is convenient to use.
