    摘要： An automotive crashworthiness energy absorption part provided at a front part or a rear part of an automotive body and absorbing crashworthiness energy by undergoing axial crush when receiving input of a crashworthiness load from a front or a rear of the automotive body includes: a tubular member configured to absorb crashworthiness energy by undergoing axial crush, the tubular member including a top portion and side wall portions continuous with the top portion; and resin coated or patched on first outer surfaces including at least outer surfaces of the top portion and the side wall portions of the tubular member. The coated or patched resin has a thickness of 8 mm or less after being heated, forms at least part of a peripheral wall portion of a closed cross section space, and is bonded to the first outer surfaces with an adhesive strength of 10 MPa or more.

    摘要： The present invention relates to extrusions for structural components, such as bumper, side impact beam, seat sill in vehicles and more particularly to a method for optimizing strength and energy absorption of 6XXX aluminium alloys extrusions by variations in thermomechanical ageing (TMA) consisting in



    i) an artificial preageing treatment with a duration t1 at a temperature T1 selected to increase the yield strength of said extrusion between 5% and 20%, said temperature T1 being typically between 120° C. and 180° C. and said duration t1 being typically between 1 and 100 hours, to obtain an artificially preaged extrusion,
    ii) a plastic deformation of said artificially preaged extrusion between 1% and 80% to obtain a deformed extrusion,
    iii) a final artificial ageing treatment of said deformed extrusion with a duration t2 at a temperature T2, said temperature T2 being typically between 140° C. and 200° C. and said the duration t2 being typically between 1 and 100 hours.

    摘要： A vehicle front compartment structure and a vehicle. The vehicle front compartment structure includes a front anti-collision beam, a front longitudinal beam, an upper side beam, and an energy-absorbing box. A side of the energy-absorbing box is connected to the front anti-collision beam. The front longitudinal beam and the upper side beam are separately connected to another side of the energy-absorbing box. A first force transmission structure is formed through the front anti-collision beam, the energy-absorbing box, and the upper side beam. A second force transmission structure is formed through the front anti-collision beam, the energy-absorbing box, and the front longitudinal beam.

    摘要： A vehicle bumper structure to be applied to a vehicle includes an impact absorber to be disposed on a front end side or a rear end side of the vehicle so as to extends in a vehicle width direction. The impact absorber includes small reaction section and a large reaction section. The small reaction section is to be disposed on an outer end side in the vehicle width direction. The small reaction section is configured to generate a predetermined reaction against a colliding object. The large reaction section is to be disposed on an inner side of the small reaction section in the vehicle width direction. The large reaction section is adjacent to the small reaction section. The large reaction section is configured to generate a larger reaction against the colliding object than the predetermined reaction.

    摘要： A pedestrian contact detection apparatus, for a vehicle, includes a bumper beam, an absorber, an upper rib, a lower rib, a contact detection sensor, and a cover. The upper rib and the lower rib each protrude from a front face of the absorber toward a vehicle front side and each extend discontinuously in a vehicle width direction. The lower rib is disposed on a vehicle lower side of the upper rib. A pressure tube extends in the vehicle width direction and is disposed between the upper rib and the lower rib. The cover covers a front face of the absorber from the vehicle front side, includes a support having insertion holes through which the upper and lower ribs are disposed, and is disposed on the vehicle front side of and adjacent to the bumper beam. The support supports the pressure tube from a vehicle rear side.
