Problems solved by technology

[0003] For example: during the operation of an electric vehicle, the on-board battery pack is constantly excited by vibrations from the road surface and the powertrain, which makes the battery pack box included in the on-board battery pack prone to fatigue failure, resulting in battery components in the battery pack box The service life of electric vehicles is reduced, and even unsafe accidents of electric vehicles occur. Therefore, how to control the impact of vibration on the vehicle battery pack during the operation of electric vehicles is particularly important.

Abstract

The invention provides a vibration isolation device, a vibration isolation system and a vehicle, and relates to the technical field of vibration attenuation. The invention aims to reduce the rigid displacement of a vehicle-mounted battery pack under the condition that the vehicle-mounted battery pack is not subjected to vibration excitation while the influence of the vibration excitation on the vehicle-mounted battery pack is reduced, thereby reducing the probability that the vehicle-mounted battery pack collides or pulls with components nearby. The vibration isolation device comprises a base,a spring member and an elastic support beam for supporting a vibration isolation object; the elastic support beam is fixed on the base; the spring member is positioned between the base and the elastic support beam; and the elastic support beam is used for generating linear buckling when the vibration isolation object is subjected to the vibration excitation. The vibration isolation device is usedin vibration attenuation of the vehicle-mounted battery pack.

Description

technical field [0001] The present application relates to the technical field of vibration reduction, in particular to a vibration isolation device, a vibration isolation system and a vehicle. Background technique [0002] Electric vehicles refer to vehicles powered by vehicle-mounted power supplies, using motors to drive wheels, and meeting the requirements of road traffic and safety regulations. Due to its smaller impact on the environment than traditional cars, its prospects are widely optimistic, but there are still some problems. [0003] For example: during the operation of an electric vehicle, the on-board battery pack is constantly excited by vibrations from the road surface and the powertrain, which makes the battery pack box included in the on-board battery pack prone to fatigue failure, resulting in battery components in the battery pack box The service life of the electric vehicle is reduced, and even an electric vehicle unsafe accident occurs. Therefore, how to...
