Embodiment Construction

[0047] In order to solve the problems that the battery box is easily cracked and damaged under inertial force, the volumetric energy density is low, and the sealing performance is poor, the invention proposes a battery box. The present invention will be further described below in conjunction with the drawings.

[0048] like figure 1 As shown, a battery case includes an upper cover (1), a sealing strip (2), a module (3) and a lower case (4).

[0049] like figure 2 As shown, the edge of the upper cover (1) has a stepped structure with two downward bends and one outward flanging, forming the first upper cover lower bend (11), upper cover outer flanging (12) and The second upper cover (1) is bent downward, and the outer flange (12) of the upper cover is provided with bolt holes B (13).

[0050] like image 3 As shown, the upper and lower surfaces of the sealing strip (2) are respectively provided with an upper boss (21) and a lower boss (22), and the sealing strip (2) is also...

Abstract

The invention relates to a battery box body, which comprises an upper cover, a sealing strip, modules and a lower box body, wherein upper bosses and lower bosses are arranged on the upper surface andthe lower surface of the sealing strip separately; mounting angles are arranged on two opposite side surfaces of each module; the mounting angles on two side surfaces of the module are horizontally arranged in a staggered manner; the horizontal heights of the mounting angles and the gravity center of each module are located in the same horizontal plane; support keels and mounting brackets of a structure shaped like a Chinese character ''ji'' are arranged in the lower box body; each module is hoisted between two adjacent mounting brackets in the lower box body; the mounting angles of two adjacent modules are horizontally arranged on the corresponding mounting brackets in a staggered manner; and the sealing strip is arranged between the upper cover and the lower box body and seals the uppercover and the lower box body through bolts. According to the battery box body, tensile breakage of torque to the box body is reduced, the volume density of the battery box body is improved by adoptingstaggered installation, the airtightness of the battery box body is improved through designing the bosses on the sealing strip; and the structure strength of the battery box body is strengthened through coordination design of the keels and the mounting brackets.

Description

technical field [0001] The invention belongs to the technical field of power battery equipment, and in particular relates to a battery box. Background technique [0002] With the increasing maturity and perfection of electric vehicle technology, electric vehicles are widely used in daily life. The power battery box is the core component of electric vehicles. Its manufacturing process includes: first, multiple batteries are connected in series and / or in parallel to form A battery module, and then multiple battery modules are connected in series and / or in parallel to form a battery box. Since the electric vehicle cannot avoid up and down bumps and wading roads during operation, this has caused two major problems that plague the development of power battery systems: 1. When the electric vehicle is bumped up and down, the module and the box will be subject to inertial force, while the current model The group and the box are fixed by setting the installation angle at the bottom ...
