Embodiment Construction

[0055] The present invention will be further described by means of embodiments below in conjunction with the accompanying drawings, but the present invention is not limited to the scope of the following embodiments.

[0056] figure 1 According to a preferred embodiment of the present invention, a quick change bracket 10 is provided.

[0057] The quick-change bracket 10 is provided with a power interface 11, which can cooperate with the connection port 21 on the battery pack 20, so as to connect the power of the battery pack 20 to the power system of the electric vehicle. The inner side of the quick-change bracket 10 is provided with a plurality of lock bases 12 , and the lock bases 12 are used to lock and fix the lock shaft 22 on the outer side of the battery pack 20 , thereby fixing the battery pack 20 relative to the quick-change bracket 10 .

[0058] The manufacturing method of quick change support 10 comprises:

[0059] 1. Extrude the aluminum profile into a preliminary ...

Abstract

The invention discloses a power exchange module and an electric vehicle comprising the same. The power exchange module comprises a quick-change bracket and a battery pack; The battery pack is installed on the quick-change bracket; The manufacturing method of the quick-change bracket is as follows: the aluminum profile is made into a workpiece through an extrusion process; Heat treatment of the extruded workpiece; Machining the workpiece after heat treatment; Tailoring and welding the machined workpieces together; Surface treatment of the tailor-welded workpiece to obtain a quick replacement bracket; The manufacturing method of the frame of the battery pack is as follows: the aluminum profile is made into a workpiece through an extrusion process; Heat treatment of the extruded workpiece; Machining the workpiece after heat treatment; Tailoring and welding the machined workpieces together; Surface treatment of tailor-welded workpiece. The tailor-welded parts are joined together to obtaina frame. The power exchange module adopts aluminum extrusion process, which not only greatly reduces the processing cost, but also improves the energy ratio of the battery pack.

Description

technical field [0001] The invention relates to a battery exchange module and an electric vehicle comprising the same. Background technique [0002] At present, pure electric vehicles and hybrid vehicles are divided into two types, one is a direct charge type, and the other is a quick change type. [0003] Direct charging is currently mainly used in some small cars, for example, taxis and family cars. As a direct charging electric vehicle, the charging pile built on the ground is currently used to pile up the vehicles for charging. However, charging piles are not only inconvenient to manage, but also with the increasing popularity of electric vehicles, it is difficult to realize centralized charging management for electric vehicles. [0004] The quick-change type is currently mainly used in the public transport system. The on-board power battery of the electric bus is quickly changed through the quick-change station, so as to realize the online continuous operation of the ...
