  • Publication number: 20220144196
    Abstract: A vehicle front structure including a left and right pair of front side members, a bumper reinforcement and a power unit. The bumper reinforcement includes a first breakage initiation point at a position at one vehicle width direction side relative to a vehicle width direction center position of the vehicle, and a second breakage initiation point at a position at the other vehicle width direction side. The first breakage initiation point is a region at which bending yield strength is lower than other regions of the bumper reinforcement. The second breakage initiation point is a region with lower bending yield strength than the other regions but higher bending yield strength than the first breakage initiation point. The bumper reinforcement includes a bumper reinforcement main body with a chamber structure and a bracing member inside the bumper reinforcement main body at the vehicle width direction center position of the vehicle.

  • Patent number: 10604093
    Abstract: A vehicle front structure includes: a bumper reinforcement; a power unit including a right device and a left device; a dash section located at a position rearward of the power unit; and a rearward supporting part provided between a dash section and the power unit. The bumper reinforcement includes a first breakage initiation point having a relatively lower bending strength than bending strengths of other portions of the bumper reinforcement. The position of the first breakage initiation point is set such that when a columnar object collides against the vicinity of the center in the vehicle width direction of the vehicle, the first breakage initiation point transfers a collision load to one of the right device and the left device which is supported by the rearward supporting part.

  • Patent number: 10434970
    Abstract: A vehicle side section structure capable of stabilizing the deployment behavior of an airbag that inflates and deploys from a side door toward a vehicle width direction outer side is obtained. An impact beam is attached to a door inner panel. The impact beam includes a support portion that supports an inflator and that includes a side-wall portion disposed at the vehicle width direction inner side of the inflator. Accordingly, reaction force from the deployment of the airbag is able to be supported by the support portion of the impact beam when the airbag inflates and deploys.

  • Patent number: 10358168
    Abstract: A crossing member disposed along a vehicle width direction between inflected portions of side members is capable of transmitting load from one of the side members to the other of the side members when the one side member deforms toward a vehicle width direction inward. Accordingly, when collision load is input due to an offset collision or the like, the collision load is transmitted from the one side member input with the collision load to the other side member through the crossing member, and the collision load is supported by the other side member.

  • Patent number: 10160493
    Abstract: A vehicle framework structure includes a tunnel, a pair of rockers, a dash cross-member, a front side member rear and a floor reinforcement. The tunnel is disposed at a vehicle width direction central portion of a floor panel of a vehicle. The rockers are disposed at each vehicle width direction outer sides of the floor panel. The dash cross-member connects front portions of the rockers with the tunnel. A front side member is disposed at the vehicle front-and-rear direction front side of the floor panel. The front side member rear is provided under the floor panel at the vehicle front-and-rear direction rear side of the front side member. A vehicle front-and-rear direction front portion of the floor reinforcement is disposed between the dash cross-member and the floor panel, and the floor reinforcement is joined to the floor panel and to the front side member rear.

  • Patent number: 10150435
    Abstract: A cross member is disposed inside a battery case. The cross member extends in the vehicle width direction at a location that overlaps with rockers as seen in the vehicle width direction. The cross member is more resistant to deformation by a load toward the battery case than a cover portion of the battery case. Therefore, when a load toward the battery case is applied, a transmission path for the load from the rocker at one vehicle width direction side to the rocker at the other vehicle width direction side may be formed by the cross member.
