Electric vehicle data recorder protecting device and method

Abstract

The invention discloses an electric vehicle data recorder protecting device and method. The device comprises a housing, both ends of the housing are provided with end covers, gaskets are arranged between the end covers and the end surfaces of the housing, and the end covers are provided with concave connectors; the side surface of the housing is provided with mounting lugs, and the housing is sequentially composed of a surface coating, a metal alloy layer, a heat insulating layer and a shock absorbing layer from outside to inside, wherein the shock absorbing layer is used for absorbing shock energy generated during travelling or accidents of a vehicle; each end cover is sequentially composed of a surface coating, a metal alloy layer and a heat insulating layer from outside to inside; the metal alloy layers are made of alpha and beta double-phase titanium alloy, and the heat insulating layers are made of sodium base heat insulating soft felt. During application, by connecting the connectors with the data recorder inside the housing through wires, the electric vehicle data recorder detecting device can collect the operating data of the vehicle in real time, and through a protecting structure with multiple function layers, ensures high mechanical strength, heat resistance, water immersion prevention and shock resistance, thereby achieving intact protection of data of the data recorder.

Description

technical field [0001] The invention relates to the field of electric vehicle protection, in particular to a protection device and a protection method for an electric vehicle data recorder. Background technique [0002] Electric vehicles mainly include pure electric vehicles and hybrid electric vehicles. Because of their advantages that traditional passenger vehicles do not have, such as low pollution, low energy consumption, and low noise, they have become non-motorized vehicles that are mainly promoted and used in my country. However, due to the addition of power batteries and high-voltage electric transmission systems to electric vehicles, the factors affecting the safety and reliability of electric vehicles have also increased accordingly. Accidents such as high-voltage system failures, high temperature generated by power batteries, and system communication failures often cause vehicles to break down midway and cause fires. [0003] Because electric vehicle safety accid...

Problems solved by technology

[0004] Existing electric vehicle data loggers can only be used in normal environments and do not have data protection functions in extreme situations. For example, when the vehicle catches fire, falls off a cliff or is submerged in floods, the data logger cannot resist the harsh external conditions. damage, resulting in data damage and loss, and it is impossible to analyze the cause of the accident afterwards
