Preferably, one side wall of the U-shaped sealing gasket is attached to the inner wall of the upper part of the L-shaped structural plate.
Preferably, the upper end of the sealing structure plate is inserted into an inward concave notch formed on the U-shaped sealing gasket.
Preferably, the spacing washer is made of a metal material.
The invention has the beneficial effects that:
according to the invention, the flat sealing gasket and the U-shaped sealing gasket are arranged at the same time, so that the sealing performance of the installation cavity of the lithium battery is ensured to be double guaranteed, and the stable and safe operation of a lithium battery power system is ensured, so that the electric locomotive can continuously operate in a high-temperature and high-humidity environment. The lithium battery structure can be widely applied to damp and hot environments, outdoor rainy environments and the like, and is beneficial to improving the operation efficiency of the electric locomotive.
Drawings
The present invention will be described in further detail with reference to the accompanying drawings and specific embodiments.
FIG. 1: the invention has a schematic structure.
In the figure: 1. the battery box comprises a battery box body, 2, bolts, 3, a box body upper shell, 4, a box body lower shell, 5, a lithium battery, 6, a sealing structure plate, 7, a transverse structure plate, 8, a cover body, 9, an L-shaped structure plate, 10, a U-shaped sealing gasket, 11, a flat sealing gasket, 12 and a limiting gasket.
Detailed Description
The embodiments of the invention will be described in detail below with reference to the attached drawings, but the invention can be implemented in many different ways, which are defined and covered by the claims:
as shown in fig. 1, the invention provides an electric locomotive lithium battery structure with a double-sealing structure, which comprises a battery box 1, wherein the battery box 1 comprises a bolt 2, a box upper shell 3 and a box lower shell 4, the box lower shell 4 is fixed with the box lower shell 4 through the bolt 2, a lithium battery 5 is arranged inside the box lower shell 4, and it can be seen that the lithium battery 5 is sealed in the box lower shell 4.
Upwards extend under the box on 4 casings and have sealed structural slab 6, casing 3 is including lid 8 and the L type structural slab 9 that extends to lid 8 below on the box, be equipped with the sealed pad 10 of U type between lid 8 and the sealed structural slab 6, the sealed 10 back-offs of U type sealed pad are on sealed structural slab 6, it can be seen that, the mode of back-offs is in the sunken notch that is equipped with on sealed structural slab 6's upper end inserted the sealed 10 of U type, the laminating of one side lateral wall of the sealed 10 of U type and the upper portion of L type structural slab 9 inner wall, consequently, when the extrusion lid 8, can carry out extrusion sealing with the sealed 10 of U type.
