Disassembling and assembling system and disassembling and assembling method for power battery box with side edge having telescopic function

Abstract

The invention discloses a disassembling and assembling system and method for a power battery box with the side edge having a telescopic function. The disassembling and assembling system comprises a vehicle body bottom plate assembly, a battery box body located below the vehicle body bottom plate assembly and a battery box disassembly and assembly mechanism capable of enabling the battery box body to be installed below the vehicle body bottom plate assembly or enabling the battery box body to be unlocked from the lower portion of the vehicle body bottom plate assembly. The battery box body is provided with a drawer type telescopic structure which can be matched and fixed with a vehicle body bottom plate assembly; the drawer type telescopic structure comprises a fixed box body which is fixed on the side surface of the battery box body, a sliding box body which is matched with the fixed box body and can translate towards the inner side or the outer side of the fixed box body relative to the fixed box body, and a battery box positioning clamping groove matched with the sliding box body is formed in the bottom of the vehicle body bottom plate assembly. The battery box disassembling and assembling mechanism comprises a shifting fork frame capable of moving left and right and a shifting fork rod arranged on the shifting fork frame and used for driving the sliding box body to move left and right, and a shifting fork sliding groove and a shifting fork hole which correspond to each other, can be matched with the shifting fork rod and drive the sliding box body to slide are formed in the fixed box body and the sliding box body respectively.

Description

technical field [0001] The invention relates to the technical field of automotive power batteries, in particular to a system and method for disassembling and disassembling a power battery box with a telescoping function on the sides. Background technique [0002] The promotion of pure plug-in electric vehicles is affected by reasons such as short driving range and long charging time. If the battery is quickly disassembled after the battery is exhausted, and the pre-charged battery is quickly installed, the continuous operation of the vehicle can be guaranteed. This is a new direction for the development of electric vehicles. The rapid replacement of the power battery system can be realized by means of the replacement equipment at the power station. So what kind of fixing method is used for the power battery box on the vehicle body to realize the quick replacement of the battery box itself is the current problem. The ordinary bolt connection is obviously Can not meet the nee...
