  • Patent number: 11479194
    Abstract: A vehicle front structure that absorbs a shock load applied to immediately under a front grille by using a structure at a position higher than a bumper beam as a support. The vehicle front structure includes a shock absorbing member at an interior of a bumper face below a front grille. The shock absorbing member includes a load receiving portion that receives a load, an abutting portion abutting against a structure above a bumper beam during receding of the shock absorbing member, an upper-side connecting portion connecting the load receiving portion and the abutting portion, a locking portion deformed while being locked to the bumper beam during receding of the shock absorbing member, and a lower-side connecting portion connecting the load receiving and locking portions. A bending facilitating portion extending in the vehicle width direction is formed on the side of a rear portion of the upper-side connecting portion.

  • Patent number: 11465688
    Abstract: A vehicle front structure that reduces a shock load applied to immediately under a front grille by using a bumper beam as a support. A vehicle front structure includes a shock absorbing member at an interior of a bumper face on the side near an upper portion thereof which absorbs a load from the diagonally upper front side. The shock absorbing member is at the interior of the bumper face below a front grille, and includes a load receiving portion that receives a load, a locking portion locked to an upper end edge of a bumper beam located behind and below the load receiving portion, at the time of receding of the shock absorbing member, and a connecting portion connecting the load receiving portion and the locking portion. A deformation facilitating portion with respect to a load from the upper front side is thus configured at the connecting portion.

  • Patent number: 11305711
    Abstract: An increased amount of absorption of a load from the diagonally upper front side is achieved even in, for example, a vehicle having a high vehicle height. A first shock absorbing member is provided inside a bumper face upper to absorb a load from the diagonally upper front side, a second shock absorbing member is mounted on a front face portion of a bumper beam, and a third shock absorbing member is disposed below the first shock absorbing member and between a bumper face and the bumper beam to absorb a load from the diagonally upper front side. The rigidity of the first and third shock absorbing members in the up-down direction is higher than rigidity of the second shock absorbing member in the front-rear direction.

  • Patent number: 10913347
    Abstract: An engine is a rear exhaust engine provided with an exhaust system component on a rear side in a vehicle front-rear direction. This engine includes a first flow rectifying member, provided above the engine, that subjects traveling wind to flow rectification so that the traveling wind flows rearward and a second flow rectifying member, disposed adjacently to a rear side of the first flow rectifying member, that subjects the traveling wind, subjected to flow rectification by the first flow rectifying member, to flow rectification so that the traveling wind is directed to the exhaust system component, in which fuel system components are disposed below the first flow rectifying member.
