  • Patent number: 9738320
    Abstract: A vehicle body front structure includes left and right front side frames including at least left and right front bending portions, left and right middle bending portions, and left and right rear bending portions. The left and right front bending portions are bent to project inwards in a vehicle's width direction by a collision load exerted on a front end of a vehicle body, whereby the left and right front bending portions restrain a power unit. The left and right middle bending portions are situated spaced apart to the rear from the left and right front bending portions. The left and right rear bending portions are situated spaced apart to the rear from the left and right middle bending portions, are bent outwards in the vehicle's width direction, and absorb collision energy when struck by the power unit moved rearward together with the left and right front bending portions.

  • Patent number: 8596711
    Abstract: A vehicle front part structure efficiently absorbs collision energy upon a narrow offset collision in which a collision object, such as an oncoming vehicle, makes a front collision with a vehicle outer side outer than a front side frame, and thereby inhibits the vehicle body front part from moving rearward to the vehicle interior side. The vehicle front part includes a pair of left/right front side frames extending along the longitudinal direction of the vehicle, and a power unit disposed at the longitudinal center between the left/right front side frames. The left/right front side frames beside the power unit include branch frames extending toward the vehicle laterally outer side. The rear end portions of the branch frames penetrate the outer surface of the left/right front side frames and extend along an inner wall. Connection members are provided at the front portions of the left/right front side frames.

  • Patent number: 6286895
    Abstract: A control device for controller rigidity of a car body has a device for adjusting rigidity of a right side frame and a left side frame extending in the longitudinal direction of a car. The device is attached to the side frames. The control device has a controller for controlling operation of the device for adjusting rigidity of the right and left side frames according to a form of collision judged by an output of a collision detector such as an acceleration sensor.

  • Patent number: 5611593
    Abstract: Disclosed is an automotive floor panel assembly, in which the floor panel assembly is stamp formed into a prescribed shape from at least one piece of sheet metal blank which consists of a first panel section made of sheet metal stock of a first thickness, and a second panel section made of sheet metal stock of a second thickness which are butt welded to each other along opposing edges thereof by using a high energy beam. Because the butt welding is carried out on flat panels, welding quality can be maintained at a high level without any substantial difficulty, and the resulting blank can have a highly uniform finish even though it includes a plurality of parts having different thicknesses. By suitably arranging the various parts having different thicknesses to different parts of the floor panel assembly in an optimum fashion, it is possible to achieve a maximum mechanical strength and a maximum rigidity with a minimum amount of material or involving a minimum weight.
