Description

  The present invention relates to a luggage compartment structure of a vehicle, and more particularly to a housing structure for emergency wheels (spare tires).

  Many automobiles accommodate spare wheels (spare tires) at the bottom of a luggage compartment (trunk room). The spare wheel housing portion is generally composed of a spare wheel housing recess (hereinafter referred to as a housing recess) formed in the floor panel of the cargo compartment and a plate-like floor lid that covers the housing recess.

  In automobiles, in order to secure a large luggage space, the volume of the receiving recess is adapted so that it is suitable for emergency wheels (temper tires) that are narrower and smaller in diameter than the wheels that are used during normal driving (hereinafter referred to as normal wheels). May be set. In this case, if the normal wheel is exchanged between the emergency wheel and the normal wheel at the time of puncture or the like, and the normal wheel is to be accommodated in the accommodation recess, the floor lid may not be completely closed due to interference with the normal wheel that does not fit in the accommodation portion. As a method for solving this problem, a bracket that supports the floor lid at an arbitrary position (height) is provided on the side wall of the luggage compartment, and the support position of the floor lid can be changed according to the size of the wheel to be accommodated. There is (for example, Patent Document 1).

A connection portion (42) connected to a part of the peripheral edge of the cover panel and having the other end connected to the floor panel. When the connection portion is deformed or displaced, the height of the cover portion relative to the floor panel is increased. It is characterized by the change.

  According to this configuration, the height of the cover part with respect to the floor panel can be changed by deforming or displacing the connecting part according to the width of the wheel, so the cover part is maintained in a state parallel to the wheel. It is possible to cover the wheels appropriately and to secure a large cargo space.

  According to a second invention, in the first invention, the connecting portion is formed of a plate-like member and is rotatably connected to each of the cover lid portion and the floor panel.

  According to this structure, the height with respect to the floor panel of a cover part can be changed by changing the inclination-angle with respect to the floor panel of a connection part.

  In a third aspect based on the second aspect, the connecting portion is formed of at least two plate-like members, and the at least two plate-like members (42A, 42B) are rotatable between adjacent end portions. It is connected.

  According to this structure, since a connection part can be bent, when changing the height with respect to the floor panel of a cover part, the variation | change_quantity of the inclination angle with respect to the floor panel of a connection part can be made small.

  According to a fourth aspect of the present invention, in any one of the first to third aspects, a side wall (16C, 61) that protrudes from the floor panel and faces the free end of the cover lid portion, and the cover lid portion extends from the side wall. A convex portion (17, 62) projecting upward from the free end, and the free end (40A) of the cover lid portion is disposed below the convex portion or at a position in contact with the convex portion. It is characterized by.

  According to this configuration, even if the height of the cover portion with respect to the floor panel is changed, it is possible to prevent the wheels from being exposed to the outside. When the height of the cover part relative to the floor panel is changed by the rotation of the connecting part, the free end of the cover part moves in a direction parallel to the floor panel. Can be concealed.

  According to a fifth invention, in any one of the first to fourth inventions, the floor panel has a recess (16) in which the wheel is accommodated, and the connection portion is outside the recess (12A). It is connected to the floor panel.

  According to this configuration, a large cargo space can be secured.

  According to the above configuration, the luggage compartment structure can accommodate wheels of various widths and can ensure a large luggage compartment space.

The lower surface 17A of the convex portion 17 is formed in a tapered shape so as to go upward as it goes forward.

  As shown in FIG. 1, a floor lid 40 that covers the recess 16 and the normal wheel 30 or the emergency wheel 31 is provided above the recess 16. The floor lid 40 includes a fixed portion 41, a connecting portion 42, and a cover lid portion 43 in this order from the front side. The fixed portion 41, the connecting portion 42, and the cover lid portion 43 are plate-like members that respectively extend in the vehicle width direction. The fixed portion 41 and the connecting portion 42 are rotatably connected by a first hinge portion 44, and the connecting portion 42 and the cover lid portion 43 are rotatably connected by a second hinge portion 45. The first hinge part 44 and the second hinge part 45 have a rotation axis substantially parallel to the vehicle width direction. The cover portion 43 is longer in the front-rear direction than the fixed portion 41 and the connecting portion 42 and covers most of the recessed portion 16 and the normal wheel 30 (the emergency wheel 31). The vehicle width direction lengths of the fixed portion 41, the coupling portion 42, and the cover lid portion 43 are longer than the vehicle width direction length of the recessed portion 16. Note that the vehicle width direction lengths of the fixing portion 41, the coupling portion 42, and the cover lid portion 43 may be shorter than the vehicle width direction length of the recessed portion 16.

  The floor lid 40 is obtained, for example, by integrally forming a flexible polymer material and forming the first hinge portion 44 and the second hinge portion 45 thin. By doing in this way, the 1st hinge part 44 and the 2nd hinge part 45 partition the fixing | fixed part 41, the connection part 42, and the cover cover part 43, and connect each part rotatably by bending deformation. To do.

  As shown in FIGS. 2 and 3, hook and loop fasteners 47 and 48 are attached to the lower surface of the fixing portion 41 and the upper surface of the rear floor panel front portion 12A, respectively, and the hook and loop fasteners 47 and 48 are coupled to each other. The fixing portion 41 is detachably fixed to the rear floor panel front portion 12A. Thereby, the connection part 42 is rotatably connected to the rear floor panel front part 12A via the fixing part 41 and the first hinge part 44. Instead of the hook-and-loop fasteners 47 and 48, the fixing portion 41 may be fixed to the rear floor panel front portion 12A with a fastening clip.

  In this way, the fixing portion 41 is fixed to the rear floor panel front portion 12A, whereby the connecting portion 42 and the cover lid portion 43 cover the concave portion 16, and the free end 40A (the rear end of the cover lid portion 43) of the floor lid 40 is covered. The concave portion 16 can be opened and closed by moving up and down. The floor lid 40 functions as a floor surface of the luggage compartment 11 in a state where the recess 16 is closed, and supports a load or the like on the upper surface thereof.

  Next, with reference to FIG. 2 and FIG. 3, the form of the floor lid 40 at the time of accommodating the emergency wheel 31 or the normal wheel 30 is demonstrated. As shown in FIG. 2, when the emergency wheel 31 is placed in the recess 16, the depth of the recess 16 is larger than the width W <b> 2 of the emergency wheel 31, so that the emergency wheel 31 does not protrude from the recess 16. Therefore, the emergency wheel 31 does not lift the floor lid 40, that is, does not interfere with the lower surface of the floor lid 40. The floor lid 40 is supported on the rear floor panel side part 12B (see FIG. 1) on both sides of the recess 16 at both ends in the vehicle width direction of the connecting part 42 and the cover part 43. In this state, the free end 40 </ b> A of the floor lid 40 extends to the lower side of the convex portion 17. Therefore, in the plan view, no gap is formed between the free end 40A of the floor lid 40 and the convex portion 17, and the emergency wheel 31 and the concave portion 16 are appropriately concealed.

  In addition, when the vehicle width direction length of the connection part 42 and the cover part 43 is shorter than the length of the recessed part 16 in the vehicle width direction, the connection part 42 and the cover part 43 are supported on the emergency wheel 31.

  As shown in FIG. 3, when the normal wheel 30 is placed in the recess 16, the normal wheel 30 protrudes from the recess 16 because the depth D of the recess 16 is smaller than the width W <b> 1 of the normal wheel 30. Therefore, the normal wheel 30 comes into contact with the lower surface of the floor lid 40 and the cover portion 43 is lifted upward by the height H1 on the normal wheel 30. At this time, since the floor lid 40 is bent at the first hinge portion 44 and the second hinge portion 45, the cover lid portion 43 is normally supported so as to be substantially parallel to the wheel 30. At this time, the floor lid 40 is bent at the first hinge portion 44 and the second hinge portion 45, whereby the free end 40A of the floor lid 40 is displaced forward. However, since the convex portion 17 is present, the floor lid 40 is free from play. The end 40 </ b> A is maintained below the convex portion 17 or in contact with the end face of the convex portion 17, and no gap is formed between the free end 40 </ b> A of the floor lid 40 and the convex portion 17 in plan view. Since the lower surface 17A of the convex portion 17 is formed in a taper shape, it does not interfere with the convex portion 17 even if the free end 40A of the floor lid 40 moves upward.

  As described above, even when the normal wheel 30 protruding from the recessed portion 16 is accommodated, the floor lid 40 can form a cargo floor surface substantially parallel to the normal wheel 30 in the cover portion 43, and the floor lid 40. In the vicinity of the free end 40A, the normal wheel 30 and the recess 16 can be appropriately concealed.

  Next, 2nd Embodiment is described with reference to FIG. 4 and FIG. 4 and 5 are cross-sectional views showing the luggage compartment according to the second embodiment, showing a state in which emergency wheels are accommodated (FIG. 4) and a state in which normal wheels are accommodated (FIG. 5). The same configurations as those of the first embodiment are denoted by the same reference numerals and description thereof is omitted. As shown in FIGS. 4 and 5, the rear floor panel 60 in the second embodiment is not formed with the recess 16 unlike the first embodiment, and the normal wheel 30 or the emergency wheel 31 is a planar rear floor panel. 60. A wall portion 61 projecting upward is formed at the rear end portion of the rear floor panel 60, and a convex portion 62 projecting forward is formed at the upper end of the wall portion 61. The lower surface 62A of the convex portion 62 is formed in a tapered shape so as to go upward as it goes forward.

  The connecting part 42 of the floor lid 40 has two plate-like members (first connecting part 42A and second connecting part 42B) extending in the vehicle width direction in the front-rear direction, and the first connecting part 42A and the second connecting part. The part 42B is rotatably connected by a third hinge part 49 having a rotation axis in the vehicle width direction. The front-rear direction widths of the first connecting portion 42A and the second connecting portion 42B are W3 and W4, respectively.

As shown in FIG. 4, when the emergency wheel 31 is placed on the rear floor panel 60, the sum of the longitudinal width W3 of the first connecting portion 42A and the longitudinal width W4 of the second connecting portion 42B is the emergency wheel. 31 is relatively large with respect to the width W2 of the cover 31, the connecting portion 42 is bent at the third hinge portion 49 so that the height H2 of the cover 43 with respect to the rear floor panel 60 corresponds to the width W2 of the emergency wheel 31, and the connecting portion The vertical length of 42 changes. Similarly, the bending angle of the first hinge portion 44 and the second hinge portion 45 also changes, and the height H2 of the cover portion 43 with respect to the rear floor panel 60 is adjusted. Thereby, the cover part 43 is supported on the upper surface of the emergency wheel 31 in parallel with the emergency wheel 31. Further, the free end A of the floor lid 40 extends below the convex portion 62, and the gap between the free end A of the floor lid 40 and the convex portion 62 is filled in a plan view.

  As shown in FIG. 5, when the normal wheel 30 is placed on the rear floor panel 60, the width W <b> 1 of the normal wheel 30 is larger than the width W <b> 2 of the emergency wheel 31. 4 corresponds to the width W1 of the normal wheel 30, and the connecting portion 42 has a smaller bending angle at the third hinge portion 49 than the case where the emergency wheel 31 of FIG. Becomes bigger. Similarly, the bending angle of the first hinge part 44 and the second hinge part 45 also changes, and the height H3 of the cover part 43 with respect to the rear floor panel 60 is adjusted. Thereby, the cover part 43 is supported on the upper surface of the normal wheel 30 in parallel with the normal wheel 30. At this time, the free end A of the floor lid 40 is displaced forward as compared with the case where the emergency wheel 31 is placed, but is in contact with the end surface of the convex portion 62 or positioned below the convex portion 62, When viewed, the gap between the free end A of the floor lid 40 and the convex portion 62 is filled.

  In the luggage compartment 11 according to the first and second embodiments described above, the height of the cover portion 43 relative to the rear floor panels 12 and 60 changes even if the widths W1 and W2 of the wheels 30 and 31 to be placed change. The wheels 30, 31 can be properly covered (become closed), and the floor surface of the horizontal luggage compartment 11 is formed. At this time, since the cover portion 43 contacts the wheels 30 and 31, the accommodation space for the wheels 30 and 31 is minimized, and a large cargo space is secured. Further, since the floor lid free end 40A extends below or contacts the convex portions 17 and 62, the wheels 30, 31 and the concave portion 16 are appropriately concealed in plan view. Is done.
