Problems solved by technology

The battery packs of electric vehicles mostly use lithium batteries. When lithium batteries are pierced or over-squeezed, deflagration accidents are extremely easy to occur, which in turn poses a hazard to the lives of passengers.
[0004]The traditional new energy battery box cannot pop out of the car body in time when the front of the car collides violently
Furthermore, there is a risk that the deformed parts in the car body caused by the car accident will pierce the battery box and battery pack, causing the battery pack to deflagrate, seriously endangering the safety of passengers in the car

Abstract

The invention discloses a new energy automobile battery box, which belongs to the technical field of new energy automobiles. The new energy automobile battery box comprises a connecting mechanism, a box body, and a cut-off cutter, wherein the connecting mechanism comprises a front connecting column, a rear connecting column, a front connecting rod and a rear connecting rod, one end of the front connecting column and one end of the rear connecting column are fixedly connected to the bottom of an automobile body; a front box lug is arranged at one end of the box body, a rear box lug is arranged at the other end of the box body, a connecting through hole formed in the front box lug is slidably connected with the front connecting rod, and a U-shaped groove formed in the rear box lug is in sliding connection with the rear connecting rod; and one end of a cutter handle of the cut-off cutter is fixedly connected with a connecting plate of the automobile energy absorption box, and a cutter edge of the cut-off cutter abuts against the front connecting rod. According to the new energy automobile battery box, when the automobile head is violently collided, the battery box can be popped out of an automobile body in time. The battery box and the battery pack are effectively prevented from being punctured by deformed parts in an automobile body due to accidents, deflagration of the battery pack is avoided, and further injury to passengers in the automobile is avoided.

Description

technical field [0001] The invention relates to the technical field of new energy vehicles, in particular to a new energy vehicle battery box. Background technique [0002] With the continuous development of my country's economy and the improvement of people's living standards, the number of cars in my country continues to grow. However, traditional fuel vehicles consume fossil fuels, which is not conducive to environmental protection, and fossil fuels are not renewable. Therefore, my country has begun to vigorously develop the new energy vehicle industry, and traditional fuel vehicles have gradually been replaced by new energy vehicles. [0003] In the field of new energy vehicles, the electric vehicle industry is the fastest growing. The battery packs of electric vehicles mostly use lithium batteries. When lithium batteries are pierced or over-squeezed, deflagration accidents are very likely to occur, which will endanger the lives of passengers. [0004] The traditional ...
