Abstract

The invention relates to a vibration isolation and manual unlocking device for a battery box of an electric automobile, which is installed between a box body and a plunger latch of the traditional quick-change battery box and is characterized by comprising a plunger latch seat, a connecting plate and a vibration isolation elastic block. By the artful connecting and fixing manner of the vibration isolation elastic block, the connecting plate and the battery box, when the battery box bears the impact force in the vertical direction, the elastic effect of the vibration isolation elastic block is used for buffering and attenuating the impact force to perform the effects of buffering and vibration isolation of the battery box; and when the battery box can not be unblocked automatically, the dismountable connecting structure on the plunger latch seat can be manually removed, and the battery box is separated from the plunger latch seat and automatically falls, thus the manually unblocking process is finished in a very simple manner so that the maintenance is convenient.

Description

technical field [0001] The utility model relates to a locking buffer and manual unlocking device for a battery box of an electric vehicle, which belongs to the technical field of electric vehicle battery replacement. Background technique [0002] As a representative of new energy vehicles, electric vehicles have received more and more attention due to their cleanliness and economy. However, due to the battery capacity and charging time, the development of electric vehicles is limited. In recent years, the combination of electric vehicle replacement stations combined with the concept of automatic quick-change equipment has ushered in the dawn of the development of electric vehicles. The concept of electric vehicle battery replacement is that when the electric vehicle battery is about to run out, enter the battery swap station to remove the battery box and replace it with a fully charged battery box. The whole battery replacement process is completed under the action of the ...
