Power supply protection device for crash test of new energy vehicle

Abstract

The invention discloses a power supply protection device for the crash test of a new energy vehicle, which includes an upper end cap, Protective housing, Power-off box, trigger plate, An upper end ofthat upper end cover is provided with a terminal seat, the terminal block is bolted to the upper end cap, A low end of that upper end cover is provided with a protective shell, The upper end cover isrotatably connected with the protective case, four connecting seats are arranged around the protective case, the connecting seats are connected with the protective case through welding, a power-off box is arranged inside the upper end cover, the power-off box is connected with the upper end cover through screws, and a terminal is arranged at the lower end of the power-off box. The invention has the advantages of reasonable structure, simple operation, convenient use, effective protection of internal battery by using a multi-layer buffer structure, and mechanical power-off to effectively ensurethat the battery can be quickly powered off when being impacted.

Description

technical field [0001] The invention relates to the field of new energy vehicles, in particular to a power supply protection device for collision testing of new energy vehicles. Background technique [0002] As environmental protection issues have attracted more and more attention from the society, it has become a general trend to replace fuel vehicles with new energy vehicles, and pure electric vehicles and gasoline-electric hybrid vehicles have gained unprecedented development opportunities. An electric vehicle or a gasoline-electric hybrid vehicle includes the core components of an electric vehicle such as a drive motor controller, a battery system, and a power line. The composition of the vehicle is much more complex than that of traditional fuel vehicles. How to effectively ensure the safety performance of the vehicle system for drivers and passengers has become the technical focus and difficulty of the vehicle system safety of pure electric vehicles and gasoline-electr...

AI Technical Summary

Problems solved by technology

When a vehicle collides, it can only protect the occupants from violent impacts, but cannot reduce or avoid the damage to the high-voltage power system of the vehicle caused by the collision, and the resulting leakage or short circuit of the high-voltage power system may cause damage People in Electric Vehicles Cause Secondary Injury

Therefore, the application of this kind of collision protection device on electric vehicles has a major defect in terms of the safety performance of the whole vehicle, but the general power protection device is controlled by electronic components, but when the power supply receives a violent impact, it is likely that the protection electronic components will also be damaged. Failure occurs and the power supply cannot be disconnected in time
