[0002] New energy vehicles refer to vehicles that use unconventional automotive fuels as their power source (or use conventional automotive fuels and adopt new on-board power devices), and integrate advanced technologies in vehicle power control and drive to form vehicles with advanced technical principles, new technologies, and new structures. New energy vehicles include pure electric vehicles, extended-range electric vehicles, hybrid electric vehicles, fuel cell electric vehicles, etc.

[0003] In Chinese patent 202220352867.3, the utility model provides a battery tray for a new energy vehicle, the battery tray comprising a tray body, the tray body being provided with a placement slot for placing the battery and a first ejection mechanism for ejecting the battery in the placement slot. The utility model solves the problem of how to make the battery tray of a new energy vehicle convenient to remove the internal battery individually and / or as a whole in the prior art.

[0004] The existing new energy vehicle battery tray has the problem that the new energy vehicle will be bumpy due to uneven roads during driving. During the bumping process, other automobile parts next to the battery will cause impact force on the battery inside the new energy vehicle, which is easy to affect the service life of the battery. During the bumping process, the battery blocks will also collide and rub against each other, and static electricity is easy to generate during the friction process, which is relatively dangerous. In addition, new energy vehicles usually have multiple battery blocks installed. When a battery block is damaged and needs to be repaired or replaced, the entire sealing cover of the battery tray needs to be opened. However, since there are many parts and a small space inside the car, when disassembling the battery and opening the sealing cover, other parts must also be disassembled to make room for this, which is a cumbersome operation.

When the bottom buffer spring 308 is subjected to external force, the spring is deformed by force and the kinetic energy of the external force is converted into elastic energy storage. This energy conversion makes the compression or stretching of the external force on the spring more uniform, and stores the kinetic energy in the spring. When the external force ends, the elastic energy stored in the spring is released, and the spring returns to its original state, transferring the stored energy to the outside world, thereby achieving a buffering effect.

At the same time, the long strip slider 306 at the bottom end of the adjustment block 305 can also slide back and forth inside the slide groove 307. By utilizing the support of the adjustment block 305 on the bottom buffer spring 308, when the battery When the battery part is subjected to impact forces in the left and right directions, the side buffer springs 204 between each battery block can also store kinetic energy inside the springs, thereby playing a buffering role. If a new energy battery block 201 is damaged and needs to be taken out for repair or replacement, it is only necessary to turn the corresponding knob 406 on the top and rotate the C-shaped block 407 at the same time, until the C-shaped block 407 is disengaged from the fixed bayonet 408, the battery sealing cover 403 can be rotated open, and then the damaged new energy battery block 201 can be taken out for repair or replacement.
