Bracket buffer device and vehicle

Abstract

The invention provides a supporting frame buffer device and a vehicle. The supporting frame buffer device comprises a supporting plate and a buffer mechanism arranged on the supporting plate, wherein a mounting plate which together with the supporting plate forms a gap is fixedly arranged on one side of the supporting plate, the buffer mechanism comprises compression springs with first ends which are fixed relative to the supporting plate and second ends which face to the mounting plate and spring lower supports which movably penetrate through the mounting plate, and the second ends of the compression springs press against the spring lower supports; the buffer mechanism further comprises elastic buffer blocks which are arranged on the surface, opposite to the supporting plate, of the mounting plate, and the end surfaces, opposite to the compression springs, of the spring lower supports at least can move to positions which are coplanar with the surfaces, opposite to the mounting plate, of the elastic buffer blocks. The supporting frame buffer device and the vehicle provided by the invention have the advantages that when the vehicle is subjected to collision impact, the buffer mechanism absorbs energy produced by collision jointly through the compression springs and the elastic buffer blocks, the supporting frame buffer device can be very quickly stabilized and the damage caused by collision is avoided.

Description

technical field [0001] The invention relates to the technical field of vehicles, in particular to a bracket buffer device and a vehicle. Background technique [0002] In the prior art, a battery is provided in a new energy vehicle to provide power, and the battery of the new energy vehicle is an expensive and fragile key device. In order to prevent the battery from being damaged in the event of a drop, a buffer mechanism needs to be provided on the pallet carrying the battery. [0003] In the prior art, buffering mechanisms for buffering impact force usually use elements made of elastic materials such as rubber or springs for buffering, but simply using elastic materials for buffering, the deformation stroke is too low, which is not conducive to the impact energy. With full absorption, the battery pack is vulnerable to potential damage; with springs for buffering, it takes a long time for the system to recover from a bumpy situation and stabilize.
