Abstract

The invention provides a chassis quick-changing battery box for electric automobile, which comprises a box body, the box body comprises a left side longitudinal beam and a right side longitudinal beam with a hollow beam structure, a hoisting spin lock used for cooperating with a hoisting installing hole on the automobile chassis is respectively arranged on the left longitudinal beam and the right side longitudinal beam, the hoisting spin locks are arranged on the left longitudinal beam and the right side longitudinal beam through an installation support in a cavity arranged in the corresponding longitudinal beam, and the installation support has a first connection part fixedly connected to the corresponding longitudinal beam and a second connection part fixedly connected to the corresponding hoisting spin lock. The connection strength of the hoisting spin lock on the left side longitudinal beam and the right side longitudinal beam can be effectively ensured by the installation support, self strength of the left and right side longitudinal beams can be effectively ensured, and the strength of the left and right side longitudinal beams can not be reduced, cavities at two sides longitudinal beams are effectively used, and the integral volume of the battery box is reduced.

Description

technical field [0001] The invention relates to a chassis quick-change battery box for an electric vehicle. Background technique [0002] With the rapid development of the battery industry, it has rapidly promoted the great development of the electric vehicle industry. At present, there are two main modes of energy supply for electric vehicles: charging and battery swapping. The charging mode is divided into slow charging and fast charging. The charging current of slow charging is relatively low, which will cause little damage to the battery, and the charging is more sufficient, but the charging time is longer. The charging current of fast charging is large, and the charging time is short, but the charging current is large, and the service life of the battery will be shortened. The battery replacement mode adopts the battery replacement mode. After the car enters the battery swap station, the battery on the car is removed, and the charged battery is reinstalled on the ...
