Novel energy-absorbing protective battery box

Abstract

The present invention provides a novel protective energy-absorbing battery box. The novel protective energy-absorbing battery box is formed by combining high-strength steel and sine wave rib plates, so that the novel protective energy-absorbing battery box is not easy to deform in the collision process of the battery box, and the sine wave rib plates can reduce the peak force in collision, the safety of the battery is protected, and the good collision resistance can be provided. An energy-absorbing column adopts a combination of a hexagonal honeycomb structure and a square structure. During crash crushing, the honeycomb structure absorbs a large amount of energy through plastic deformation. Meanwhile, the energy-absorbing column is also provided with the square structure, and a large number of corner units provided by the energy-absorbing column can absorb energy in the collision process, so that the safety of the battery is protected. A battery pressing plate is a sandwich structure,the inner layer is a self-similar structure consisting of an isosceles trapezoid and a rectangle, and the yield strength and the energy absorption capacity of the pressing plate can be adjusted by changing the number of self-similar layers and the self-similar proportion, so that the battery pressing plate has the good energy-absorbing performance. The protective energy-absorbing battery box can provide enough buffering energy absorption when collision occurs.

Description

technical field [0001] The invention relates to the field of electric vehicle battery components, more specifically, the invention is a novel protective energy-absorbing battery box. Background technique [0002] In recent years, with the rapid development of new energy vehicles, the safety of the vehicle's power battery box has gradually become a key research topic. In today's automobile market, the proportion of new energy vehicles is increasing year by year. Although new energy vehicles have more advantages than traditional vehicles in terms of energy consumption and environmental issues, in the event of a collision, the batteries of new energy vehicles are prone to fire, burn or even explode, endangering the personal safety of drivers. In order to improve the anti-collision performance of the automobile lithium battery box and improve the driving safety of the car, it is necessary to improve the existing battery box. Therefore, it has very important practical significa...
