The invention belongs to the technical field of vehicle suspensions, and particularly relates to a cushioning device for a lightweight chassis of a new energy vehicle, which comprises a chassis, the upper end of the chassis is connected with the same mounting plate through a plurality of dampers, and the cushioning device further comprises a battery protection mounting mechanism and a vibration deformation air supply compensation mechanism. According to the invention, the heat dissipation spaces of the battery modules can be filled when the chassis vibrates, so that the problem that the use safety of the battery modules is influenced by collision and vibration transmission between the battery modules is avoided, and the heat dissipation channels between the battery modules are opened again when no vibration exists; the heat dissipation quality of the battery module is ensured, the current vibration intensity can be automatically confirmed based on the air supply degree change caused by the vibration intensity, and when the vibration intensity is too large and reaches a threshold value, a signal is fed back to control the battery management system to start an active voltage balance program and automatically regulate and control the temperature monitoring frequency and the temperature early warning threshold value. And the driving safety is better ensured.
本发明属于车辆悬架技术领域,尤其是涉及一种新能源汽车轻量化底盘的缓震装置,包括底盘,所述底盘的上端通过多个减震器连接有同一个安装板,还包括:电池保护安装机构、震动形变供气补偿机构。本发明能够在底盘产生震动的时候对电池模组的散热空间进行填充,避免电池模组之间的碰撞和震动传递对电池模组的使用安全性造成影响的问题,且在没有震动的时候使得多个电池模组之间的散热通道重新打开,确保电池模组的散热质量,能够基于震动强度所造成的供气程度变化来自动确认当前的震动强度,并在震动强度过大达到阈值时反馈信号控制电池管理系统启动主动电压平衡程序和对温度监测频率、温度预警阈值进行自动调控,更好的确保行车安全。
