Description

  The present invention relates to a back panel and a cargo bed structure that separate a vehicle cargo bed and a cabin.

  Conventionally, as a back panel of this type, in a vibration isolating structure for an automobile back panel that defines a driver's cab and a cargo compartment, a reinforcing bead extending in the vehicle body vertical direction is formed on the back panel in parallel in the vehicle width direction. In addition, the pitch in the vehicle width direction of each bead is set to an unequal pitch so that the center in the vehicle width direction is denser from the outside, thereby suppressing vibration noise generated during traveling (for example, Patent Documents) 1) In the back panel of a cab provided with a number of vertical beads, the lower portions of the plurality of vertical beads in the vicinity of the belt anchor fixed to the floor are separated from the welded portion of the floor and the back panel by a large distance upward. When a load is input to the floor portion by linkage with a bead, a portion that prevents local deformation (for example, Patent Document 2) or a vehicle that is erected along the vehicle width direction, A cab back panel comprising: a base portion; and a plurality of beads bent from the base portion and extending in a vertical direction and arranged in a vehicle width direction, wherein the plurality of beads are separated from the base portion. A first bead that protrudes in the direction and a second bead that protrudes in the other direction of the vehicle front and rear of the vehicle, and in the first region on both sides in the vehicle width direction of the base portion, Of the beads, only the first bead is provided, and only the second bead among the plurality of beads is provided in the second region of the base portion in the vehicle width direction. There is one that achieves weight reduction by further reducing the plate thickness while ensuring the surface rigidity necessary for suppressing occurrence (for example, Patent Document 3).

  By the way, various loads are loaded on the loading platform at the rear of the back panel. For example, when mounting a motorcycle, if the loading platform is too short, it may not be loaded or mounted at an angle. In particular, it may be difficult to load a small transport vehicle.

  In addition, a fixing belt (for example, Patent Document 4) is used to fix the load on the loading platform. The fixing belt is hung on a motorcycle, and both ends of the fixing belt are hooked on the loading platform hook and fixed. However, it is necessary to maintain the posture of the motorcycle until it is fixed by the fixing belt, and it is difficult to work alone, and it is necessary to work by a plurality of people. Further, since the wheels are not fixed by a tire stop or the like, it is necessary to fix the wheels with a plurality of fixing belts.

  Furthermore, if the motorcycle has a stand on one side and is made to stand independently by the stand, the vehicle body becomes slanted, so the fixing work by the fixing belt becomes complicated, and the vehicle body is supported at three points: the front wheel, the rear wheel, and the stand. Therefore, if the fixing belt is pressed against the cargo bed, an excessive force may be applied to the stand.

  On the other hand, as a tire stopper, a tire fixing tool (for example, Patent Document 5) having a fitting groove into which the front and rear tires of a motorcycle are fitted has been proposed, and the tire is fitted by fitting the tire into the fitting groove. Can be prevented, and the fixing work using the fixing belt can be performed alone.

  However, when the tire fixing tool is fixed to the loading platform, the tire fixing tool becomes an obstacle when a vehicle other than a motorcycle is loaded. Therefore, even if the tire fixing tool is detachably provided, it must be attached and detached each time, and the work becomes complicated.

  In addition, since the distance between the front end and the rear end of the front and rear tire fixing tools is longer than the entire length of the motorcycle, it is not suitable for use because it takes up space in a narrow platform.

  And in the back panel of the said prior art, although suppression of vibration noise (patent document 1), deformation | transformation prevention (patent document 2), and ensuring of surface rigidity (patent document 3) are considered, about conveyance of a loaded vehicle Is not considered.
