Description

  The present invention relates to a spare tire storage unit for a vehicle.

A recess for storing a spare tire is formed in a rear floor panel of an automobile, and a spare tire is generally stored horizontally in the recess. In the vehicle having such a configuration, the spare tire is stored so that the spare tire that moves forward in accordance with the deformation of the rear portion of the vehicle body at the time of the rear collision does not crush the fuel tank or the like disposed in front of the recess. The front wall of the recess is provided with an upwardly inclined surface, and when a large force from the rear is applied to the spare tire, the front portion of the spare tire is placed on the cargo floor along the inclined surface. A vehicle body structure has been proposed (see Patent Documents 1 and 2).

  On the other hand, in a so-called hybrid vehicle in which a gasoline engine and an electric motor are used in combination as a driving source for wheels, an electrical device such as a battery may be disposed between the passenger compartment and the cargo compartment. In such a vehicle, when the rear tire collides as described above, the measure of simply riding the spare tire on the cargo floor is such that the spare tire moving forward hits the battery and the expensive battery cannot be reused. It cannot be prevented from being damaged.

  It may be possible to set up a dedicated vehicle body for hybrid vehicles that have been designed to prevent the spare tire from hitting the battery etc. in the event of a rear collision, but the number of hybrid vehicles produced is small, and sharing with the vehicle body of a gasoline engine vehicle is a manufacturing cost. It is indispensable to reduce.

  The present invention has been devised to solve such problems of the prior art, and its main purpose is to make it possible to share the body of a hybrid vehicle and a gasoline engine vehicle, and to spare in the case of a hybrid vehicle. It is an object of the present invention to provide a vehicle spare tire storage unit that can take measures to prevent a tire from hitting a battery or the like.

The present invention in order to achieve the above object, the spare tire storage unit for a vehicle formed by providing the inclined surface of the front up to the front wall 4 of the recess 1 provided on the rear floor panel FP, the upper end of the front wall 4 A substantially horizontal upper surface extending rearward from the portion, a rear surface 8 which is inclined from the rear end of the upper surface at a steeper angle than the inclined surface of the front wall 4 and becomes a second inclined surface, and is continuous with the upper surface and the rear surface And the left and right side surfaces, and a brace 5 having a closed box shape when the front wall 4 is fixed to the rear side .

  According to the present invention, in the case of a rear collision of a gasoline engine vehicle, the spare tire is moved forward on the inclined surface of the front wall of the original recess, and in the case of a rear collision of the hybrid vehicle, the brace is moved forward. The spare tire can be flipped up further upward by the second inclined surface obtained by being attached to the wall. This makes it possible to share the vehicle body between the gasoline engine vehicle and the hybrid vehicle, and simply select the presence or absence of braces, and in the case of a hybrid vehicle, spare tires for electrical components such as batteries installed between the passenger compartment and the luggage compartment. Can be prevented from hitting.

  Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

  FIG. 1 schematically shows a rear floor panel FP located in a trunk room of a vehicle body constructed according to the present invention. The rear floor panel FP is press-formed with a steel plate, and a recess 1 for storing a spare tire is integrally formed at the rearmost portion in the center in the vehicle width direction. A bracket 3 to which a fixing bolt is screwed is fixed at the center of the recess 1 viewed from above the bottom wall 2 through a center hole or a clip bolt hole of a wheel of a spare tire placed horizontally. The rear floor panel FP is configured so that required rigidity can be obtained by a bead, a cross member, a side beam, and the like extending in the vehicle body width direction and the front-rear direction, but these are not related to the essence of the present invention. The description is omitted.

  As shown in FIG. 2, the front wall 4 of the recess 1 forms an inclined surface that rises forward at an appropriate angle (for example, 45 degrees with respect to the horizontal). The front wall 4 is configured such that a brace 5 formed of a separate member is selectively detachable using, for example, a plurality of bolts.

  The brace 5 is formed by press-molding a steel plate, and the upper surface, the rear surface, and both the left and right side surfaces are closed. When this is joined to the front wall 4 of the recess 1, a box-shaped closed cross section is formed. It has become.

  On the rear surface of the brace 5, the shoulder 7 of the spare tire 6 a indicated by a solid line on the base side of the brace 5 and an angle somewhat steeper than the angle of the front wall 4 of the recess 1 (for example, 60 degrees) a second inclined surface 8 is formed.

  The brace 5 is attached only to the vehicle body for the hybrid vehicle.

  In the case of a gasoline engine vehicle, the brace 5 is not attached to the front wall 4 of the recess 1. Accordingly, the front portion of the spare tire 6b stored horizontally is positioned near the boundary between the bottom wall 2 and the front wall 4 of the recess 1 as indicated by a two-dot chain line. On the other hand, in the case of a hybrid vehicle, since the brace 5 is attached, as shown by the solid line, the shoulder portion of the portion located on the front side of the spare tire 6a is placed on the step portion 7 of the brace 5 and is raised somewhat forward The positional relationship of each part is set so that it may be mounted inclined.

  As a result, when the spare tire 6a is pushed forward in the case of a rear collision in the hybrid vehicle, the front portion of the spare tire 6a jumps upward along the second inclined surface 8 of the brace 5 as indicated by an arrow. It is done. That is, the trajectory of the front portion of the spare tire 6a bounced up by the second inclined surface 8 is shifted rearward as compared with the case of a gasoline engine vehicle. The spare tire 6a does not hit the electrical component 9.

  When the position and angle of the inclined surface (second inclined surface 8) corresponding to the hybrid vehicle are also applied to the gasoline engine vehicle, there is no inconvenience with respect to the trajectory of the spare tire 6b at the time of the rear collision. However, the position and angle of the inclined surface of the hybrid vehicle are useless settings for the gasoline engine vehicle, and there is a disadvantage that the space of the spare tire storage portion must be sacrificed. According to the present invention, it is possible to easily cope with the difference in specifications using a common vehicle body by simply attaching the brace 5, so that in the case of a gasoline engine vehicle, the spare tire storage portion is connected to a jack or a tool. There is no problem in using it as a storage location.

It is a schematic perspective view of the spare tire storage part to which this invention is applied. It is a cross-sectional outline figure which follows the vehicle body front-back direction centerline of a spare tire storage part.
