Description

Front Structure for Vehicle The present invention relates to a vehicle front structure, and more specifically, to a vehicle front structure capable of stably inducing the lateral movement of a vehicle during a vehicle collision. The crashworthiness of vehicles is tested through various tests such as frontal impacts, side impacts, rear impacts, and roll-over. Recently, the small overlap test, which simulates small overlap frontal crashes against a rigid barrier, was introduced by the Insurance Institute for Highway Safety (IIHS). Electric vehicles are configured to induce lateral movement of the vehicle to reduce body damage, passenger injury, and battery damage in the event of a small overlap collision. Conventional electric vehicles include a bumper deflector provided at the end of the front bumper, a side deflector provided on the front side member, and a crossbar connecting a pair of front side members along the width direction of the vehicle to induce lateral movement in the event of a vehicle collision. Accordingly, when a vehicle collision occurs, the load is transferred to the crossbar through the bumper deflector and the side deflector, thereby inducing lateral movement of the vehicle. However, conventional electric vehicles require bumper deflectors, side deflectors, and crossbars to induce lateral movement, which can make their front structure complex and has the disadvantage of relatively high weight and manufacturing costs. In addition, crossbars are made of aluminum to enhance fracture characteristics compared to steel, which has the disadvantage of relatively higher manufacturing costs. The matters described in this background technology section are written to enhance understanding of the background of the invention and may include matters that are not prior art already known to those skilled in the art to which this technology belongs.
