A motor vehicle has at least one pressure vessel for storing storage medium, preferably fuel, at least one pressure relief device for pressure relief of the at least one pressure vessel, and at least one opening through which storage medium flows out during a pressure relief.

A cylindrical hydrogen tank is housed under a floor tunnel, which is disposed at the center in a vehicle width direction of a floor panel along a vehicle front-back direction so as to protrude upward along a height direction, and includes a casing having a load bearing property. A seat cross member is disposed on a side of the hydrogen tank along the vehicle width direction. A seat pipe is joined to the seat cross member and disposed so as to extend along the vehicle width direction. The seat pipe and the seat cross member are arranged within the height of the hydrogen tank in a vehicle height direction, and also respectively located above and below the most outwardly protruded lateral end point in the vehicle width direction of the hydrogen tank.

Typical composite panels are brittle and unable to support transverse pressure loads that might be imposed on the panels. For example, the use of typical panels around fuel tanks of a vehicle are unable to support transverse pressure loads that might be imposed on the fuel tanks during a crash of the vehicle or a ballistic impact to the fuel tanks. In the embodiments described herein, panels include face sheets that are bonded to a foam core. The foam core includes a corrugated core sheet that is formed from a highly ductile material, such as Polyethylene or Aluminum. When a transverse pressure load is imposed on the panel, core crush of the foam occurs as the core sheet elongates from its original corrugated shape to a curve shape during deformation. This allows the panel to dissipate the energy of the transverse pressure load applied to the panel.

A vehicle includes a vehicle body having a frame structure provided with a pair of right and left side rails, and hydrogen tanks and a secondary battery disposed in a region between the side rails. The side rails have deformed portions that are deformed due to a vehicle front collision load at the time of a vehicle front collision, and the hydrogen tanks are disposed in front of the secondary battery or on both outer sides of the secondary battery in a vehicle width direction such that the deformed portions, when the amount of movement of each of the deformed portions of the side rails has reached a predetermined amount, reach the hydrogen tanks without reaching the secondary battery.

This disclosure relates to an assembly that cools a traction battery of a vehicle, in particular a hybrid electric vehicle. The assembly can include at least one fuel tank, and at least one traction battery that is arranged outside the fuel tank and is thermally connected to the fuel tank. The assembly can further include at least one fuel pump that is arranged in the fuel tank and at least one fuel line that is connected and/or can be connected to a pressure side of the fuel pump. A connection portion of the fuel tank is thermally connected to the traction battery. Fuel can be used to cool the connection portion, which cools the traction battery.

A structure for a lower portion of a vehicle body includes a right side sill (14), a right floor frame (17), a right cross member (68), and a muffler. A fuel tank is provided on an inner side of the right floor frame (17) in a vehicle width direction. The right cross member (68) spans between the right floor frame (17) and the right side sill (14) and extends in the vehicle width direction. Furthermore, the muffler is provided in a region enclosed by the right side sill (14), the right floor frame (17), and the right cross member (68). The right cross member (68) has an upward deformation guiding part (77). The upward deformation guiding part (77) is formed to be able to be deformed upward due to an impact load (F2) input to the right side sill (14).

A lower body structure of a vehicle includes: a left and right pair of left seat rails and a left and right pair of right seat rails configured to make left and right seats of a second-row seat independently slidable; a first cross member including securing portions to which the left seat rails and the right seat rails are secured; a second cross member disposed apart from the first cross member in a vehicle fore-and-aft direction; and a first coupling member that couples the first cross member and the second cross member to each other in the vehicle fore-and-aft direction. The first coupling member is located between the securing portion located on a left side of the right seat rails and the securing portion located on a right side of the left seat rails in a vehicle width direction.

A motorcycle includes an extended and lower frame arrangement, a front wheel coupled to the extended and lower frame arrangement via a front wheel extension member to frontwardly extend a distance between the extended and lower frame arrangement and the front wheel, a rear wheel coupled to the extended and lower frame arrangement via a widen hub assembly to rearwardly extend a distance between the extended and lower frame arrangement and the rear wheel, such that the front wheel and the rear wheel are shifted far from the extended and lowered frame arrangement to lengthen a distance between the front wheel and the rear wheel so as to further lower a center of gravity of the motorcycle.
