Description

Technical Field

[0001] The present application relates to the technical field of battery pack protection structures, and in particular to a battery pack armor plate structure and a vehicle. Background Art

[0002] Typically, when extended-range off-road electric vehicles are sold, in order to facilitate maintenance, the vehicle chassis components such as wiring, fuel tanks, exhaust pipes, battery packs, etc. are mostly exposed to the outside or simply protected with low-strength and easily removable plastic guards.

[0003] With this arrangement, when the vehicle is driving in the city or on the highway, the off-road vehicle chassis has a relatively high ground clearance, so it can meet the protection requirements. However, when the vehicle is driving off-road in mountainous, gravel, muddy and other harsh road conditions, the vehicle chassis is often damaged by external impact and gravel impact due to road conditions. In addition, the acid, alkali and salt substances on the road surface can easily invade the vehicle chassis and stay for a long time, corroding the structure of the parts. For extended-range off-road electric vehicles, a large-capacity battery pack is installed in the middle of the vehicle chassis. The battery pack box is large in size and exposed on the outside. Once the bottom is bumped and corroded, the battery pack is very likely to catch fire, leak electricity and other risks. In addition, the bottom guard plate of the battery pack body is often fixed to the battery pack frame beam with bolts. Once the fixing bolts are scratched and deformed by external forces, the air tightness of the battery pack box will fail easily.

[0004] Therefore, it is necessary to install a high-strength metal chassis armor plate for off-road conditions. However, conventional metal chassis armor plates do not provide all-round protection for the bottom of the battery pack, especially in terms of avoiding the accumulation of foreign matter such as mud and sand, and there is no effective measure.
