Abstract

The invention discloses an electric vehicle battery quick change device, further discloses an electric vehicle, and further discloses an electric vehicle battery quick change method. The electric vehicle battery quick change device comprises a fixing plate, a first sliding block and a second sliding block. The fixing plate is provided with a perforation, a first track and a second track communicating with the first track. The first sliding block is disposed in the first track, the first sliding block can slide in the first track, the second sliding block is disposed in the second track, and the second sliding block can slide in the second track. The first sliding block is connected with the second sliding block through a connecting rod, and the first sliding block and the second sliding block are linked to move. The perforation is used for being connected with a vehicle body longitudinal beam matching block. The electric vehicle battery quick change device adopts a pure mechanical motion mechanism, realizes fixing and locking of the mechanism by the sliding block movement, and has a good locking effect; the electric vehicle battery quick change device is in interference fit with avehicle body to facilitate maintenance, a power part of the quick change device is located on a battery changing tray, vehicle body connecting equipment is simple, and the overall lightweight effect is good; and the installation operation is simple and fast, the disassembly is convenient, and the firmness is high and the cost is low.

Description

technical field [0001] The invention relates to the technical field of electric vehicle battery replacement, in particular to an electric vehicle battery quick-change device, an electric vehicle and a quick-change method. Background technique [0002] In recent years, in the face of the increasingly unbalanced supply and demand of traditional energy and the severe situation of global warming, countries have stepped up their efforts in the development and application of new energy and new energy technologies. As a new energy vehicle, electric vehicles have the characteristics of low noise, high energy utilization rate, and no mobile exhaust emissions. They have become one of the strategic emerging industries supported by my country. The energy supply mode is an important link in the electric vehicle industry chain, which directly determines the lifeline of the industry's development. There are mainly two ways of energy supply for electric vehicles: fast charging and slow cha...
