A vehicle radiator apparatus includes: a radiator main body; a grill shutter unit configured to adjust the amount of air introduced from an opening in front of the radiator main body and flowing toward the radiator main body; and an air guiding plate provided to extend in a longitudinal direction below the radiator main body and the grill shutter unit to guide the air introduced from the opening to the radiator main body, in which the grill shutter unit includes: a shutter member configured to open or close the opening of a vehicle; and a shutter support member configured to support the shutter member, and including left and right side frame portions and an upper frame portion, and lower ends of the side frame portions are assembled and attached to an upper surface portion of the air guiding plate.

Vehicle radiator apparatus

A bumper device for a vehicle is arranged on one of a front side and a rear side of a vehicle cabin to extend in a vehicle width direction. The bumper device for a vehicle includes: a tubular portion, which is made of metal and integrally formed so as to have a tubular shape extending in the vehicle width direction; and a reinforcing member, which is formed so as to have a plate-like shape extending in the vehicle width direction along an inner surface of the tubular portion. A foamed resin charged into the tubular portion is foamed to be increased in volume, to thereby fix the reinforcing member inside the tubular portion.

Bumper device for a vehicle

A vehicle door impact beam disposed between first and second door panels includes: a first grooved portion configured to include a bottom wall portion extending along the first door panel in a predetermined direction, and side wall portions; a second grooved portion disposed a predetermined gap away from the first grooved portion in the width direction, and configured to include a bottom wall portion and side wall portions respectively connected to both end portions of the bottom wall portion in the width direction; and a connection wall portion configured to connect one side wall portion, which is one of the side wall portions of the first grooved portion and positioned on a second grooved portion side, to one side wall portion which is one of the side wall portions of the second grooved portion and positioned on a first grooved portion side.

Vehicle door impact beam

A tubular-shaped shock absorbing member arranged at a side end portion of a vehicle, includes outer and inner wall portions each extending in a vehicle height direction and a vehicle front-and-rear direction, the inner wall portion being arranged on a center portion side of the vehicle, an upper wall portion connected to upper end portions of the inner and outer wall portions, a lower wall portion connected to lower end portions of the inner and outer wall portions, and a horizontal rib connected to the inner and outer wall portions. A distance between the upper and lower wall portions is decreased as approaching from the inner wall portion side to the outer wall portion side. A thickness of a part of the horizontal rib connected to the outer wall portion, is larger than a thickness of a part of the horizontal rib connected to the inner wall portion.

Shock absorbing member

A shock absorbing member provided between a side member extending in a front-rear direction of a vehicle and a bumper reinforcement extending in a vehicle width direction and provided at the side member, includes: a shock absorbing portion, which extends in the front-rear direction of the vehicle and is supported by the side member and which is configured to absorb an impact caused by a load by being compressed in the front-rear direction of the vehicle when the load is applied to the bumper reinforcement in at least one of a forward direction and a backward direction; and a bumper reinforcing portion, which extends from an end portion side closer to the side member in the impact absorbing portion toward a vehicle-width-direction outside and a bumper reinforcement side and which reinforces the vehicle-width-direction end portion side of the bumper reinforcement.

A vehicle bumper apparatus includes a bumper reinforcement member formed to have a hollow cross section and including a vehicle interior portion formed to have an open cross section including an opening, and a crush box supporting the bumper reinforcement member to mount the bumper reinforcement member to a side member of a vehicle body, the crush box including a connecting portion arranged at a vehicle exterior portion, the connecting portion closing the opening of the bumper reinforcement member to restrict the opening from being expanded, and a retaining portion protruding from the connecting portion toward an exterior side of a vehicle to retain the bumper reinforcement member.

Vehicle bumper apparatus and crush box thereof

A shock absorber includes a cylindrical small diameter portion, a cylindrical large diameter portion, and an annular step portion that connects the small diameter portion and the large diameter portion to each other. The shock absorber absorbs load applied thereto through plastic deformation that starts at the annular step portion thereby absorbing impact energy. In the deformation, the small diameter portion is folded back into the large diameter portion. The large diameter portion has protrusions, which extend in the axial direction and protrude radially outward. Therefore, the shock absorber stabilizes turning deformation and is capable of efficiently absorbing impact energy. A bumper device for a vehicle is also provided.

Shock absorber and bumper device for vehicle

A crush box arranged between a side member of a vehicle body and a bumper reinforcement member, the crush box including: a main body portion arranged in a longitudinal direction of a vehicle and formed in a tubular shape, the main body portion having first and second portions; a vehicle body attaching portion arranged at a first end of the main body portion; and a bumper attaching portion arranged at a second end of the main body portion, wherein vertical cross-sections of both the first portion adjacent to the vehicle body attaching portion and the second portion adjacent to the bumper attaching portion are polygonal shapes, and the number of vertices of the polygonal shape of the vertical cross-section of the second portion is greater than the number of vertices of the polygonal shape of the vertical cross-section of the first portion.

Crush box and vehicle bumper apparatus including the same

A bumper reinforcement includes a front wall portion, an upper wall portion, and a lower wall portion. The front wall portion constitutes the front portion of the bumper reinforcement. The upper wall portion constitutes the upper half of the rear portion of the bumper reinforcement. The lower wall portion, connected to the lower edge of the front wall portion, constitutes the lower half of the rear portion. Outer grooves, formed by denting the front wall portion rearward, extend along the vehicle width direction. Upper grooves, formed by denting downward a top wall of the upper wall portion, are located intermittently along the width direction and extend in the longitudinal direction. The lower wall portion comprises a bottom wall constituting the bottom of the lower wall portion. Lower grooves, formed by denting the lower wall portion upward, are located intermittently along the width direction and extend in the longitudinal direction.
