Problems solved by technology

[0007] Due to the overlapping of multiple parts in the power battery housing assembly of a pure electric car, it is easy to cause poor sealing, especially at the corner position. In the prior art, the connecting piece connecting the two parts is generally directly welded on the connect the top of the two parts and then proceed to glue the
Although this method is easy to operate, when the power battery case assembly and the upper case assembly are fitted together, the connection will affect the seal.
In addition, in the prior art, the plug-in shield is generally glued from the inside and then welded, which makes it difficult to apply glue and it is not easy to evenly apply glue and seal

Embodiment Construction

[0031] For clarity, the following will be described in combination with a rectangular coordinate system, where the side closer to the origin O is the inner side, and the side farther from the origin O is the outer side, whether in the front-rear direction or in the left-right direction.

[0032] refer to figure 1 , the power battery housing assembly 1 of the pure electric car is used for arranging the power battery in the bottom space of the car.

[0033] refer to figure 2 , in this embodiment, the power battery case assembly 1 uses at least two bottom plates 9 , and the two bottom plates 9 are connected by the middle longitudinal beam 3 and the tray 5 . In the absence of central stringers 3 and trays 5 , it is also possible to use a single bottom plate 9 . In this embodiment, the middle longitudinal beam 3 is a sealed box-shaped structure, which can strengthen the structural strength of the power battery case assembly 1 . The upper surface of the middle longitudinal beam ...

Abstract

The invention provides a power battery housing assembly for an electric automobile. The power battery housing assembly comprises a base plate, an outer plate and a plurality of connecting pieces, wherein the outer plate is fixed to the base plate and surrounds the base plate to form a power battery accommodating space. The outer plate comprises a front beam outer plate, a rear beam outer plate, a left longitudinal beam outer plate and a right longitudinal beam outer plate. The connecting pieces are respectively located at the corner position connected with the front beam outer plate and the left longitudinal beam outer plate, the corner position connected with the front beam outer plate and the right longitudinal beam outer plate, the corner position connected with the rear beam outer plate and the left longitudinal beam outer plate and the corner position of the rear beam outer plate and the right longitudinal beam outer plate. The upper surfaces of the connecting pieces and the connecting pieces and the upper surfaces of the outer plates connected with the connecting pieces are on the same plane. The sealing performance of the power battery housing assembly can be guaranteed.

Description

technical field [0001] The invention relates to the field of pure electric cars, in particular to a power battery housing assembly of a pure electric car. Background technique [0002] The power battery assembly of a pure electric car includes key components such as battery modules, BDU (battery disconnect unit), and LBC (centralized management system) controller. Since most of the current pure electric cars are developed on the basis of the original internal combustion locomotive, generally speaking, without sacrificing the space of the passenger compartment and the comfort of the whole vehicle, the space at the bottom of the vehicle body becomes the power battery assembly of the pure electric car. into the main space arranged. Due to the limitation of layout space, it is the best solution for the industrialization of pure electric cars to design a power battery housing assembly that meets the requirements of carrying capacity, anti-collision, and good sealing. [0003] T...
