Yes (see, for example, Patent Document 1).

JP 2007-76401 A

  The floor member in the above structure is formed in a plate shape that secures a certain degree of strength so that it can take two states: when the bottom surface of the trunk room is flattened by covering the upper surface of the recess, and when accommodated in the recess. The When used in a flattened state on the bottom surface of the trunk room, the floor member is supported by the edge of the recess (for example, the edge in the vehicle front-rear direction), and a large load is applied to the floor member by the load in that state. When the is added, the floor member may be bent. In order to prevent the floor member from being bent even when a large load is applied, in order to increase the strength of the floor member, for example, it is possible to increase the thickness of the floor member or to provide a rib or a bead. The floor member becomes large and increases in weight, resulting in a problem that handling properties deteriorate.

  In order to solve such a problem and realize a trunk room structure capable of improving load resistance without sacrificing handleability in a floor member covering a recess provided at the bottom of the trunk room, in the present invention, A recess (2) provided at the bottom of the trunk room (1), a floor member (13) covering the upper surface of the recess (2), and the floor member (13) at a first position and the first position. A trunk room structure having a support member (11) capable of being selectively placed at a second position higher than the upper position of the recess (2) below the first position. And a load transmission member (9) that integrally supports the support member (11) and is fixed on the bridge member (5).

  In particular, the electrical component (3) is disposed below the bridging member (5), and the bridging member (5) fixes the electrical component (3) to the trunk room (1). It is good that it is a bracket.

  As described above, according to the present invention, when the floor member is supported by the support member at the second position higher than the first position, the load transmission member integrated with the support member is bridged across the upper surface of the recess. Since the load from the load on the floor member is transmitted from the support member to the bridging member via the load transmitting member, the load can be received by the bridging member and the strength of the bridging member. The bending of the floor member can be suppressed by ensuring the above.

  In particular, when the electrical component is stored below the bridging member, it is possible to prevent the electrical component from being damaged due to the bending of the floor member. Moreover, since the bracket which supports an electrical component is a bridging member, it is not necessary to provide a bridging member separately, and an increase in the number of parts can be suppressed.

It is a perspective view which shows the principal part of the trunk room of the motor vehicle to which this invention was applied. It is a side cross-sectional enlarged view which shows the structure of the load transmission member based on this invention. (A) is the perspective view which located the trunk floor lid in the lower stage, (b) is the perspective view which located the trunk floor lid in the upper stage.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings. FIG. 1 is a perspective view showing a main part of a trunk room of an automobile (hybrid vehicle) to which the present invention is applied.

  In the illustrated vehicle, the bottom of the trunk room 1 is provided with a recess 2 having an opening area that is slightly smaller than, for example, the bottom surface of the trunk room 1. In the recess 2, a spare tire (not shown) is stored, or a tire repair tool or the like is stored in a vehicle not equipped with a spare tire. Further, the recess 2 houses a protective cover 4 that houses an electrical component 3 for operating the motor / generator of the hybrid vehicle. Examples of the electrical component 3 include a battery module, an inverter, and a DC-DC converter.

  In the illustrated example as a bracket for fixing the protective cover 4 (electrical component 3) to the trunk room 1, two bridging members 5 are arranged in the vehicle width direction at a predetermined interval in the vehicle front-rear direction. It is provided so that it may extend. The intermediate portion of the bridging member 5 crosses the lower surface of the lid member 4a of the protective cover 4 and is screwed to the lid member 4a. Both ends of the bridging member 5 are fixed by bolts with the inner panel 7 sandwiched between the left and right rear side frames 6 of the vehicle, and a protective cover 4 (electrical component 3) is attached to the trunk room 1 in a suspended state.

  A plate-like bracket 8 is attached to the upper surface of the lid member 4a corresponding to the intermediate portion of the bridging member 5 on the vehicle front side with a bolt. A bottom wall portion of the load transmission member 9 molded like the shape of the portion is attached. The load transmitting member 9 is integrally formed with a jaw portion 9a protruding toward the vehicle rear side, and a support member 11 is attached to the upper surface of the jaw portion 9a in an upright state. The support member 11 is formed such that the steel plate is bent into a substantially Z shape in a side view.

  A front panel 12 formed by molding a synthetic resin material so as to have a cross-sectional shape covering the load transmitting member 9 and bending it as shown by a two-dot chain line in FIG. It has been. The support members 11 are disposed at three locations at predetermined intervals in the vehicle width direction including those provided integrally with the load transmission member 9 described above, and each of the support members on both sides of the load transmission member 9 is provided. 11 is attached to a position on the left and right side walls of the protective cover 4 in the lid member 4a.

  As shown in FIGS. 3 (a) and 3 (b), a trunk floor lid 13 made of a plate-like body as a floor member forming the bottom surface of the trunk room 1 is selectively placed on the upper surface of the recess 2 at different heights. Be able to. The vehicle front side portion of the trunk floor lid 13 is supported by the support member 11.

  As shown in FIG. 2, the support member 11 is provided with a head portion 11a corresponding to the upper side and a leg portion 11b corresponding to the lower side in the Z-shape so as to protrude rearward of the vehicle at different heights. Thus, the vehicle front side portion of the trunk floor lid 13 can be placed in two steps, high and low. The vehicle rear side portion of the trunk floor lid 13 is selectively supported by two upper and lower projecting step portions formed on the rear end panel (not shown) according to the height difference of the support member 11 by pressing. It has become.

  The front panel 12 includes an upper portion 12a that is substantially the same height as the upper surface of the head portion 11a of the support member 11, and a lower step portion 12b that is flush with the upper surface of the leg portion 11b. On both sides of the trunk room 1 (left and right parts of the vehicle), left and right side panels 14 having portions that are the same height as the upper stage part 12a and the lower stage part 12b are provided.

  Further, as shown in FIGS. 3A and 3B, interior materials 15a and 15b each having a size corresponding to each of the upper panel portions of the front panel 12 and the side panel 14 are placed. Yes. As shown in FIG. 3A, the upper surface of the trunk floor lid 13 placed on the head 11a of the support member 11 and the upper surfaces of the interior members 15a and 15b are made to have the same height. Yes. As shown in FIG. 3B, the trunk floor lid 13 placed on the legs 11 b of the support member 11 includes the lower projecting stepped portion of the rear end panel and the left and right side panels 14. Supported by each lower part.

  Thus, the trunk room 1 can be efficiently used according to the size and shape of the load by positioning the trunk floor lid 13 at a height difference between the upper side and the lower side. In the state where the trunk floor lid 13 is placed on the lower side, the four sides of the trunk floor lid 13 are supported, so that the load due to the load placed on the trunk floor lid 13 is dispersed.

  On the other hand, in a state where the trunk floor lid 13 is placed on the upper stage side, the trunk floor lid 13 is supported by two sides before and after the trunk floor lid 13 by the head portion 11a of the support member 11 and the upper protruding step portion of the rear end panel. Therefore, the load applied to each side becomes large. In particular, when the electrical component 3 is disposed in the front portion of the trunk room 1 and the support member 11 is positioned on the protective cover 4 as in the illustrated vehicle, the large size is provided on the trunk floor lid 13. If a heavy load is applied to the lid member 4a via the support member 11 by placing a heavy object, the lid member 4a may be bent.

  According to the structure of the present embodiment, as described above, the central support member 11 is supported by the load transmission member 9, and the load transmission member 9 is supported by the bridging member 5 as a strength member. Therefore, when a load F acts on the central support member 11 from the trunk floor lid 13 side as indicated by an arrow A in FIG. 2, the load F is applied to the load transmitting member 9 as indicated by a solid line arrow in the figure. Is transmitted to the bridging member 5. By increasing the bending strength of the bridging member 5, the load F acting on the central support member 11 can be received by the bridging member 5, and the lid member 4a can be prevented from being bent by the load F. . Since the support members 11 on both sides are attached to positions on the left and right side walls of the protective cover 4 in the lid member 4a, the load can be received in the vertical direction by the side walls of the protective cover 4. The load can be received without problems.

  Further, since the load is received by the load transmitting member 9 and the bridging member 5, it is not necessary to increase the rigidity of the trunk floor lid 13 so much, so the weight of the trunk floor lid 13 does not increase and the height position is changed. In this case, the handleability of the trunk floor lid 13 is not sacrificed. In addition, according to this Embodiment, the leg part 11b of the support member 11 is also received by the load transmission member 9, and the load in the case of using the trunk floor lid 13 in the lower stage can also be received by the bridging member 5. .

  Thereby, the bad influence with respect to the electrical component 3 by the bending of the cover member 4a is also prevented, and by minimizing the strength of the holding member of the electrical component 3 and the protective cover 4, their weight increase is suppressed, and the vehicle Weight reduction can be promoted. The bridging member 5 can be easily made lightweight and high in bending strength by forming each pipe shape with a hollow rectangular cross section as shown in FIG.

  Further, the bridging member 5 is used as a protective cover 4, that is, a bracket for mounting the electrical component 3 to the trunk room 1, and can also reduce the number of components by being used as a strength member for receiving the load F. It can also have an effect.

  In the illustrated example, the load transmitting member 9 is provided at one place in the center in the vehicle width direction. However, two or more places may be provided depending on the load resistance design. Moreover, although the selection of the height position of the trunk floor lid 13 is made two steps, the invention can be similarly applied even when there are three or more steps.
