[0001] The present invention relates to a moving deck module. [Background technology]

[0002] A luggage floor device as described in Patent Document 1 is known as a conventional movable deck module. The luggage floor device described in Patent Document 1 is disposed at the rear of the vehicle. The luggage floor device includes a luggage floor that is provided so as to be substantially flush with the floor surface of the luggage room, and a floor support means that supports the luggage floor so as to be swingable in the vertical direction and slidable in the horizontal direction. The floor support means has a pair of guide rails that are spaced apart in the vehicle width direction. [Prior art documents] [Patent documents]

[0003] [Patent Document 1] JP 2003-341431 A Summary of the Invention [Problem to be solved by the invention]

[0004] However, the above-mentioned conventional technology does not take into consideration collisions, so that when a vehicle is rear-ended, there is a possibility that the moving deck module will come into contact with the rear seat and push the rear seat in.

[0005] An object of the present invention is to provide a moving deck module that can suppress pushing of the rear seats when the vehicle is hit from behind. [Means for solving the problem]

[0006] One aspect of the present invention is a movable deck module provided in a luggage compartment located at the rear of a vehicle, comprising a base member, a movable deck movable in the fore-and-aft direction of the vehicle relative to the base member, and a first support part that connects one of the front and rear end parts of the base member to the body of the vehicle and supports the base member against the body, the first support part being attached to the body such that when a load is input to the body from the rear of the vehicle, deformation of the body allows the base member to rotate in the vertical direction of the vehicle relative to the body.

[0007] In such a moving deck module, the first support portion that supports the base member relative to the vehicle body is attached to the vehicle body so that when a load is input to the vehicle body from the rear of the vehicle, the deformation of the vehicle body allows the base member to rotate in the vertical direction of the vehicle relative to the vehicle body. Therefore, when the vehicle is rear-ended and a collision load is input to the vehicle body from the rear, the first support portion causes the base member to rotate upward relative to the vehicle body, so that the base member is lifted together with the moving deck. This reduces the amount of movement of the base member and the moving deck toward the front of the vehicle. This prevents the moving deck module from pushing in the rear seats when the vehicle is rear-ended.

[0008] The moving deck module may further include a second support portion that connects the other of the front end portion and the rear end portion of the base member to the vehicle body and cooperates with the first support portion to support the base member to the vehicle body. In this configuration, the base member is supported to the vehicle body by the first support portion and the second support portion, increasing the rigidity of the moving deck module. Therefore, when luggage is placed on the moving deck, the load of the luggage can be efficiently received in the vertical direction of the vehicle.

[0009] The second support part may connect the other of the front end part and the rear end part of the base member to the vehicle body so as to incline downward toward the opposite side of the first support part. In such a configuration, when a load is input to the vehicle body from the rear of the vehicle, the second support part may trigger the rotation of the base member due to deformation of the vehicle body. Therefore, when the vehicle is rear-ended and a collision load is input to the vehicle body from the rear of the vehicle, the base member rotates smoothly above the vehicle relative to the vehicle body, making it easier for the base member and the moving deck to be lifted.

[0010] The second support part may have an inclined part attached to the other of the front end part and the rear end part of the base member so as to incline downward toward the opposite side of the first support part, and an upright part connected to the inclined part and fixed to the vehicle body so as to extend in the vertical direction of the vehicle. In this configuration, the upright part is fixed to the vehicle body so as to extend in the vertical direction of the vehicle, and the inclined part is connected to the upright part, so that the rigidity of the moving deck module is further increased. Therefore, when luggage is placed on the moving deck, the load of the luggage can be more efficiently received in the vertical direction of the vehicle.

[0011] The moving deck module may further include a third support portion that connects a portion of the base member between the first support portion and the second support portion to the vehicle body and cooperates with the first support portion and the second support portion to support the base member to the vehicle body. In this configuration, the base member is supported to the vehicle body by the first support portion, the second support portion, and the third support portion, so that the rigidity of the moving deck module is further increased. Therefore, when luggage is placed on the moving deck, the load of the luggage can be received more efficiently in the vertical direction of the vehicle.

[0012] The base member may be provided with a recess that becomes the starting point of the base member breaking due to deformation of the vehicle body when a load is input to the vehicle body from the rear of the vehicle. In such a configuration, when the vehicle is rear-ended and a collision load is input to the vehicle body from the rear of the vehicle, the base member rotates upward relative to the vehicle body due to deformation of the vehicle body, and the base member breaks at the recess. This further reduces the amount of movement of the base member and the moving deck toward the front of the vehicle. In addition, the moving deck may also rotate upward relative to the vehicle following the base member and break. In this case, the amount of reduction in the volume of the luggage compartment is suppressed, so that, for example, luggage placed on the moving deck is less likely to deform.

[0013] The recess may be provided so as to open on the upper surface of the base member. In such a configuration, when a collision load is input to the vehicle body from the rear of the vehicle, the base member is likely to break upward from the recess. Therefore, the folding direction of the base member coincides with the rotation direction of the base member, so that the base member and the moving deck are likely to be lifted up.

[0014] The first support portion may connect a front end portion of the base member to the vehicle body. In this configuration, when the vehicle is rear-ended and a collision load is input to the vehicle body from the rear of the vehicle, the rear portion of the base member and the moving deck are lifted. Therefore, the colliding object goes under the base member, causing the base member to rotate further above the vehicle relative to the vehicle body. This causes the base member and the moving deck to be sufficiently lifted.

[0015] A recess may be provided in a portion of the base member between the first support portion and the second support portion, which serves as a starting point for bending the base member into an inverted V shape due to deformation of the vehicle body when a load is input to the vehicle body from the rear of the vehicle. In this configuration, when the vehicle is rear-ended and a collision load is input to the vehicle body from the rear of the vehicle, the base member rotates upward relative to the vehicle body due to deformation of the vehicle body, and the base member bends into an inverted V shape starting from the recess. Therefore, the amount of movement of the base member and the moving deck toward the front of the vehicle is further reduced.

[0016] The first support portion may connect a front end portion of the base member to the vehicle body, the second support portion may connect a rear end portion of the base member to the vehicle body, and the recess may be provided at a position on the base member rearward of the center of the vehicle in the fore-and-aft direction. In this configuration, when the vehicle is rear-ended and a collision load is input to the vehicle body from the rear of the vehicle, the amount of rotation of the base member relative to the vehicle body is reduced, so that the tilt angle of the moving deck relative to the vehicle body can be small. This prevents the base member and the moving deck from being lifted too high. Therefore, for example, luggage placed on the moving deck is less likely to deform.

[0017] The base member has a pair of left and right rails extending in the front-rear direction of the vehicle, the front end portion of the moving deck is provided with multiple sets of left and right engagement parts that engage with the rails and move along the rails, and the recess may be provided at a position rearward of the multiple sets of engagement parts on the base member when the moving deck is stored in the luggage compartment. In such a configuration, when the vehicle is rear-ended with the moving deck stored in the luggage compartment and a collision load is input to the vehicle body from the rear of the vehicle, the base member bends into an inverted V shape starting from the recess, but the moving deck is less likely to bend. Therefore, damage to the moving deck can be suppressed.

[0018] The recess may be provided in the base member so that when a load is input to the vehicle body from the rear of the vehicle, the moving deck is tilted at an angle relative to the vehicle body so that it fits within the luggage compartment. In this configuration, even if the vehicle is rear-ended and a collision load is input to the vehicle body from the rear of the vehicle, the moving deck fits within the luggage compartment, making it less likely for the moving deck to interfere with the vehicle body. This further reduces damage to the moving deck.

[0019] The movable deck module may further include a third support part attached to a portion of the vehicle body between the first support part and the second support part and supporting the base member against the vehicle body in cooperation with the first support part and the second support part, and a connector for detachably connecting the base member and the third support part. In this configuration, the base member is supported against the vehicle body by the first support part, the second support part, and the third support part, so that the rigidity of the movable deck module is further increased. Therefore, when luggage is placed on the movable deck, the load of the luggage can be more efficiently received in the vertical direction of the vehicle. In addition, when the vehicle is rear-ended and a collision load is input to the vehicle body from the rear of the vehicle, the connection between the base member and the third support part by the connector is released, so that the bending of the base member caused by the recess is not hindered.

[0020] The third support portion may be located directly below the recess. In this configuration, the third support portion effectively suppresses a decrease in the rigidity of the moving deck module caused by providing a recess in the base member. Therefore, even if heavy luggage is placed on the moving deck, the load of the luggage can be sufficiently supported in the vertical direction of the vehicle.

[0021] The connector may have a connecting member fixed to the base member, and a pressing member fixed to the third support portion and pressing the connecting member against the third support portion. In such a configuration, in a normal state, the pressing member presses the connecting member against the third support portion, thereby connecting the base member and the third support portion. When a collision load is input to the vehicle body from the rear of the vehicle, the base member bends in an inverted V shape, causing the connecting member to come out of the pressing member, and the connection between the base member and the third support portion is released. In this way, the connector can be realized with a simple structure. Effect of the Invention

[0022] According to the present invention, it is possible to suppress pushing of the rear seat when the vehicle is hit from behind. [Brief description of the drawings]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0024] Hereinafter, an embodiment of the present invention will be described in detail with reference to the drawings. In the drawings, the same or equivalent elements are designated by the same reference numerals, and duplicated explanations will be omitted.

[0025] Fig. 1 is a schematic perspective view showing the rear of a vehicle equipped with a movable deck module according to a first embodiment of the present invention. In Fig. 1, the vehicle 1 has a vehicle body 2. A roof panel 3 is provided on the upper part of the vehicle body 2, and side panels 4 are provided on both sides of the vehicle body 2. A rear bumper 5 is disposed on the lower rear side of the vehicle body 2. An opening 6 defined by the roof panel 3, the side panel 4 and the rear bumper 5 is provided at the rear end of the vehicle body 2. The opening 6 is opened and closed by a back door 7, as shown in Fig. 2.

[0026] A luggage compartment 8 in which luggage M (see FIG. 9) is loaded is disposed at the rear of the vehicle 1. The luggage compartment 8 is disposed in an area behind the rear seats 9 of the vehicle 1. The luggage compartment 8 is equipped with a movable deck module 10 of this embodiment.

[0027] 2 and 3, the moving deck module 10 includes a frame-shaped base member 11 and a moving deck 12 that is movable in the fore-and-aft direction of the vehicle 1 relative to the base member 11. Fig. 2 is a schematic side view showing the rear of the vehicle 1. Fig. 3 is an exploded perspective view of the moving deck module 10.

[0028] The moving deck 12 includes a frame-shaped support 13 attached to the base member 11 so as to be movable in the fore-and-aft direction of the vehicle 1, and a flat deck board 14 attached to the support 13 so as to be movable in the fore-and-aft direction of the vehicle 1. Note that Fig. 1(a) shows a schematic diagram of the moving deck 12 stored in the luggage compartment 8. Fig. 1(b) shows a schematic diagram of the moving deck 12 pulled out from the luggage compartment 8.

[0029] The base member 11 is supported on the vehicle body 2 via two left and right front support parts 15 and two left and right rear support parts 16. The front support parts 15 and the rear support parts 16 will be described in detail later. A convex rail 17 extending in the fore-and-aft direction of the vehicle 1 is provided on the upper part of both the left and right sides of the base member 11. In addition, a slide block 18 is provided adjacent to the rail 17 on the upper part of the rear end part of both the left and right sides of the base member 11.

[0030] The support 13 is attached to the base member 11 so as to be slidable in the front-rear direction of the vehicle 1. Slide blocks 19 that fit into rails 17 of the base member 11 are provided near the front end of the lower left and right sides of the support 13. The slide blocks 19 are engagement parts that engage with the rails 17 and move along the rails 17. In addition, convex rails 20 that extend in the front-rear direction of the vehicle 1 are provided adjacent to the slide blocks 19 at the lower left and right sides of the support 13. The slide blocks 18 of the base member 11 fit into the rails 20. The slide blocks 18 form engagement parts that engage with the rails 20 and move along the rails 20.

[0031] Therefore, the support 13 is movably supported on the base member 11 by the two slide blocks 18 and the two slide blocks 19. Rails 21 extending in the front-rear direction of the vehicle 1 are provided on the upper left and right sides of the support 13.

[0032] Deck board 14 is attached to supports 13 so as to be slidable in the fore-and-aft direction of vehicle 1. Slide blocks 22 that fit into rails 21 of supports 13 are provided on the front and rear sides of the lower part of both the left and right sides of deck board 14. Slide blocks 22 are engagement parts that engage with rails 21 and move along rails 21. Thus, deck board 14 is movably supported on supports 13 by four slide blocks 22.

[0033] In addition, although not specifically shown, the movable deck module 10 is equipped with a mechanism for locking the movable deck 12 to the base member 11 when the movable deck 12 is stored in the luggage compartment 8 and when the movable deck 12 is pulled out rearward from the luggage compartment 8.

[0034] The front support part 15 connects the front end part of the base member 11 to the rear frame 24 that constitutes a part of the vehicle body 2, and supports the base member 11 with respect to the vehicle body 2. The front support part 15 constitutes a first support part that connects one of the front end part and the rear end part of the base member 11 to the vehicle body 2. One end of the front support part 15 is attached to the front end part of the base member 11 by pin joining or the like. The other end of the front support part 15 is attached to the front end part of the rear frame 24 by pin joining or the like.

[0035] The rear support part 16 connects the rear end portion of the base member 11 to the rear frame 24, and cooperates with the front support part 15 to support the base member 11 relative to the vehicle body 2. The rear support part 16 constitutes a second support part that connects the other of the front end portion and the rear end portion of the base member 11 to the vehicle body 2. One end of the rear support part 16 is attached near the rear end of the base member 11 by a pin joint or the like. The other end of the rear support part 16 is attached to the rear end portion of the rear frame 24 by a pin joint or the like.

[0036] The rear frame 24 has a pair of left and right rear side members 25 extending in the front-rear direction of the vehicle 1, a rear cross member 26 extending in the left-right direction (vehicle width direction) of the vehicle 1 and connecting the rear side members 25 together, and a rear reinforcement 27 extending in the left-right direction of the vehicle 1 and connecting the rear side members 25 together behind the rear cross member 26. Both ends of the rear cross member 26 are fixed to front portions of the rear side members 25. The rear cross member 26 protrudes from, for example, an upper surface of the rear side member 25. The rear reinforcement 27 is disposed, for example, above the rear side member 25 and reinforces the rear frame 24 in cooperation with the rear cross member 26.

[0037] Further, a bumper reinforcement 28 extending in the left-right direction of the vehicle 1 is disposed on the rear side of the rear side member 25. The bumper reinforcement 28 reinforces the rear bumper 5.

[0038] Both ends of the front support portion 15 are attached to the front end of the base member 11 and the rear cross member 26 of the rear frame 24 so as to incline downward toward the front of the vehicle 1. In addition, both ends of the front support portion 15 are attached to the front end of the base member 11 and the rear cross member 26 so that when a load is input to the rear frame 24 of the vehicle body 2 from the rear of the vehicle 1, the rear frame 24 deforms and the base member 11 is capable of rotating relative to the rear frame 24 in the vertical direction of the vehicle 1.

[0039] Both ends of the front support part 15 may be attached to the front end part of the base member 11 and the rear cross member 26, respectively, so as to extend straight in the fore-and-aft direction of the vehicle 1. Also, both ends of the front support part 15 may be attached to the front end part of the base member 11 and the front end part of the rear side member 25, respectively.

[0040] Both ends of the rear support portion 16 are attached near the rear end of the base member 11 and to the rear end of the rear side member 25 of the rear frame 24, respectively, so as to slope downward toward the rear of the vehicle 1 (the opposite side of the front support portion 15).

[0041] In the movable deck module 10 configured as described above, when the movable deck 12 is stored in the luggage compartment 8 and a collision test barrier 30 collides with the vehicle 1 from behind as shown in Fig. 4(a), a collision load is input to the rear bumper 5 and the rear frame 24 of the vehicle body 2. Then, the rear frame 24 is pushed forward of the vehicle 1 and deformed.

[0042] At this time, as shown in Fig. 4(b), the rear support portion 16 triggers the base member 11 to rotate upward of the vehicle 1 relative to the rear frame 24 via the front support portion 15. At this time, the base member 11 rotates with any point of the front support portion 15 as a fulcrum. As a result, the rear portions of the base member 11 and the moving deck 12 are lifted up.

[0043] Then, when the rear frame 24 is further pushed forward of the vehicle 1, the barrier 30 enters under the moving deck module 10 as shown in Fig. 4(c). Therefore, the base member 11 further rotates upward relative to the rear frame 24 of the vehicle 1 via the front support portion 15, so that the rear portions of the base member 11 and the moving deck 12 are further lifted.

[0044] Fig. 5 is a schematic side view showing the rear of a vehicle equipped with a moving deck module as a comparative example, together with the operation of the moving deck module. In Fig. 5, the moving deck module 100 of this comparative example has two front support parts 101 on the left and right and two rear support parts 102 on the left and right that support the base member 11 on the rear frame 24 of the vehicle body 2. The front support parts 101 and the rear support parts 102 extend straight in the vertical direction of the vehicle 1.

[0045] In this comparative example, as shown in Fig. 5(a), when the barrier 30 collides with the vehicle 1 from behind, the rear frame 24 is pushed forward of the vehicle 1 and deformed. Then, as shown in Fig. 5(b), the movable deck module 100 hits the rear seat 9 and pushes the rear seat 9 in.

[0046] To address such a problem, in this embodiment, the front support portion 15 that supports the base member 11 relative to the vehicle body 2 is attached to the vehicle body 2 so that when a load is input to the vehicle body 2 from the rear of the vehicle 1, the deformation of the vehicle body 2 causes the base member 11 to rotate in the vertical direction of the vehicle 1 relative to the vehicle body 2. Therefore, when the vehicle 1 is rear-ended and a collision load is input to the vehicle body 2 from the rear of the vehicle 1, the front support portion 15 causes the base member 11 to rotate upward relative to the vehicle body 2, so that the base member 11 is lifted together with the moving deck 12. This reduces the amount of movement of the base member 11 and the moving deck 12 toward the front of the vehicle 1. This prevents the moving deck module 10 from pushing in the rear seat 9 when the vehicle 1 is rear-ended.

[0047] Furthermore, in this embodiment, a rear support portion 16 is provided that supports the base member 11 relative to the vehicle body 2. Therefore, the base member 11 is supported relative to the vehicle body 2 by the front support portion 15 and the rear support portion 16, increasing the rigidity of the moving deck module 10. As a result, when luggage is placed on the moving deck 12, the load of the luggage can be efficiently received in the vertical direction of the vehicle 1.

[0048] Furthermore, in this embodiment, the rear support portion 16 connects the rear end portion of the base member 11 to the vehicle body 2 so as to incline downward toward the rear of the vehicle 1. For this reason, when a load is input to the vehicle body 2 from the rear of the vehicle 1, the rear support portion 16 can trigger the rotation of the base member 11 due to deformation of the vehicle body 2. Therefore, when the vehicle 1 is rear-ended and a collision load is input to the vehicle body 2 from the rear of the vehicle 1, the base member 11 rotates smoothly above the vehicle 1 relative to the vehicle body 2, making it easier for the base member 11 and the moving deck 12 to be lifted.

[0049] Furthermore, in this embodiment, when the vehicle 1 is rear-ended and a collision load is input to the vehicle body 2 from the rear of the vehicle 1, the rear portions of the base member 11 and the moving deck 12 are lifted. Therefore, the barrier 30 (the object that has been hit from behind) gets under the base member 11, causing the base member 11 to rotate further upward of the vehicle 1 relative to the vehicle body 2. As a result, the base member 11 and the moving deck 12 are sufficiently lifted.

[0050] In this embodiment, the base member 11 is supported on the rear frame 24 of the vehicle body 2 by the front support portion 15 and the rear support portion 16, but this is not particularly limited to such a configuration. For example, the front end portion of the base member 11 may be supported on the rear frame 24 via the front support portion 15, and the rear end portion of the base member 11 may be directly supported on the rear frame 24.

[0051] 6 is a schematic side view showing the rear of a vehicle equipped with a moving deck module according to a second embodiment of the present invention, together with the operation of the moving deck module. In FIG. 6, the moving deck module 10A of this embodiment includes a front support portion 35 and a rear support portion 36 instead of the front support portion 15 and the rear support portion 16 described above.

[0052] The rear support part 36 constitutes a first support part that connects one of the front end part and the rear end part of the base member 11 to the rear frame 24 of the vehicle body 2. One end of the rear support part 36 is attached to the rear end part of the base member 11 by pin joining or the like. The other end of the rear support part 36 is attached to the rear end part of the rear side member 25 of the rear frame 24 by pin joining or the like.

[0053] Both ends of the rear support part 36 are attached to the rear end of the base member 11 and the rear end of the rear side member 25, respectively, so that when a load is input to the rear frame 24 from the rear of the vehicle 1, the base member 11 is able to rotate in the vertical direction of the vehicle 1 relative to the rear frame 24 due to deformation of the rear frame 24. Note that both ends of the rear support part 36 may be attached to the rear end of the base member 11 and the rear reinforcement 27, respectively.

[0054] The front support part 35 constitutes a second support part that connects the other of the front end part and the rear end part of the base member 11 to the rear frame 24. One end of the front support part 35 is attached to the front end part of the base member 11 by a pin joint or the like. The other end of the front support part 35 is attached to the front end part of the rear side member 25 of the rear frame 24 by a pin joint or the like.

[0055] Both ends of the front support part 35 are attached to the front end part of the base member 11 and the front end part of the rear side member 25, respectively, so as to slope downward toward the front side of the vehicle 1 (the opposite side of the rear support part 36). Note that both ends of the front support part 35 may be attached to the front end part of the base member 11 and the rear cross member 26, respectively, so as to slope downward toward the front side of the vehicle 1.

[0056] In the movable deck module 10A as described above, when a collision test barrier 30 collides with the vehicle 1 from behind, the rear bumper 5 and the rear frame 24 are pushed forward of the vehicle 1 and deformed, as shown in Fig. 6(a). Then, as shown in Fig. 6(b), the front support part 35 triggers the base member 11 to rotate upward relative to the rear frame 24 via the rear support part 36. At this time, the base member 11 rotates with any point of the rear support part 36 as a fulcrum. As a result, the front parts of the base member 11 and the movable deck 12 are lifted up.

[0057] In this manner, in this embodiment, when the vehicle 1 is rear-ended and a collision load is input from the rear of the vehicle 1 to the vehicle body 2, the rear support portion 36 causes the base member 11 to rotate upward of the vehicle 1 relative to the vehicle body 2. This prevents the moving deck module 10 from pushing in the rear seat 9 when the vehicle 1 is rear-ended, similar to the first embodiment described above.

[0058] Fig. 7 is a schematic side view showing the rear of a vehicle equipped with a moving deck module according to a third embodiment of the present invention. Fig. 8 is an exploded perspective view of the moving deck module shown in Fig. 7. In Figs. 7 and 8, the moving deck module 10B of this embodiment has two intermediate support parts 41 on the left and right in addition to the configuration in the first embodiment described above.

[0059] The intermediate support portion 41 connects a portion of the base member 11 between the front support portion 15 and the rear support portion 16 to the rear frame 24 of the vehicle body 2, and constitutes a third support portion that cooperates with the front support portion 15 and the rear support portion 16 to support the base member 11 relative to the vehicle body 2. The intermediate support portion 41 extends straight in the up-down direction of the vehicle 1.

[0060] One end of the intermediate support part 41 is fixed, for example, by welding or the like to a middle portion between the front support part 15 and the rear support part 16 of the base member 11. The other end of the intermediate support part 41 is fixed to the rear side member 25 of the rear frame 24 by fastening a bolt or the like.

[0061] The base member 11 is provided with recesses 42 on both the left and right sides, which become starting points for the base member 11 to break due to deformation of the rear frame 24 when a load is input to the rear frame 24 from the rear of the vehicle 1. The recesses 42 are provided in a middle portion of the rail 17 of the base member 11 in the front-rear direction of the vehicle 1. In other words, the middle support portion 41 is located directly below the recesses 42. The recesses 42 are provided so as to open to the upper surface of the rail 17 of the base member 11. The recesses 42 are, for example, a notch having a V-shaped cross section.

[0062] In the moving deck module 10B as described above, as shown in Fig. 9(a), when a collision test barrier 30 collides with the vehicle 1 from behind, a collision load is input to the rear bumper 5 and the rear frame 24. Then, as shown in Fig. 9(b), the base member 11 rotates upward relative to the rear frame 24 via the front support part 15, so that the rear portions of the base member 11 and the moving deck 12 are lifted.

[0063] 9(b), the base member 11 begins to bend in a V-shape above the vehicle 1, starting from a recess 42 provided in the base member 11. As a result, the moving deck 12 follows the base member 11 and bends in a V-shape above the vehicle 1. Note that the V-shape mentioned here includes not only a perfect V-shape but also an approximate V-shape.

[0064] In this embodiment, an intermediate support part 41 is provided that connects the portion of the base member 11 between the front support part 15 and the rear support part 16 to the vehicle body 2 and supports the base member 11 to the vehicle body 2. Therefore, the base member 11 is supported to the vehicle body 2 by the front support part 15, the rear support part 16, and the intermediate support part 41, so that the rigidity of the movable deck module 10B is further increased. Therefore, when luggage is placed on the movable deck 12, the load of the luggage can be received in the vertical direction of the vehicle 1 more efficiently.

[0065] In addition, in this embodiment, when a load is input to the vehicle body 2 from the rear of the vehicle 1, the base member 11 is provided with a recess 42 that becomes the starting point of the breakage of the base member 11 due to the deformation of the vehicle body 2. Therefore, when the vehicle 1 is rear-ended and a collision load is input to the vehicle body 2 from the rear of the vehicle 1, the base member 11 rotates upward relative to the vehicle body 2 due to the deformation of the vehicle body 2, and the base member 11 breaks starting from the recess 42. Therefore, the amount of movement of the base member 11 and the moving deck 12 toward the front of the vehicle 1 is further reduced. In addition, the moving deck 12 also rotates upward and breaks following the base member 11. Therefore, the amount of reduction in the capacity of the luggage compartment 8 is suppressed, so that, for example, the baggage M placed on the moving deck 12 is less likely to deform (see FIG. 9(b)).

[0066] Moreover, in this embodiment, the recess 42 is provided so as to open on the upper surface of the base member 11. Therefore, when a collision load is input to the vehicle body 2 from the rear of the vehicle 1, the base member 11 is likely to break upward of the vehicle 1, triggered by the recess 42. Therefore, the folding direction of the base member 11 coincides with the rotation direction of the base member 11, so that the base member 11 and the moving deck 12 are likely to be lifted.

[0067] Furthermore, in this embodiment, the intermediate support part 41 is located directly below the recessed part 42 of the base member 11. Therefore, the intermediate support part 41 effectively suppresses a decrease in the rigidity of the moving deck module 10B caused by providing the recessed part 42 in the base member 11. Therefore, even if heavy luggage is placed on the moving deck 12, the load of the luggage can be sufficiently received in the vertical direction of the vehicle 1.

[0068] In this embodiment, the intermediate support part 41 is located directly below the recessed part 42 of the base member 11, but is not limited to this particular form. The intermediate support part 41 may be disposed at a position shifted in the front-rear direction of the vehicle 1 with respect to the recessed part 42. In addition, such a recessed part 42 does not have to be provided in the base member 11.

[0069] 10 is a schematic side view showing the rear of a vehicle equipped with a moving deck module according to a fourth embodiment of the present invention, together with the operation of the moving deck module. In FIG. 10, in the moving deck module 10C of this embodiment, the recess 42 which is the starting point of folding of the base member 11 is provided so as to open to the underside of the base member 11.

[0070] As shown in Fig. 10(a), when the barrier 30 collides with the vehicle 1 from behind, a collision load is input to the rear bumper 5 and the rear frame 24. Then, as shown in Fig. 10(b), the base member 11 rotates upward relative to the rear frame 24 via the front support portion 15, so that the base member 11 and the moving deck 12 are lifted.

[0071] 10(b), the base member 11 begins to bend downwardly into an inverted V shape from the recess 42 provided in the base member 11. As a result, the moving deck 12 follows the base member 11 and bends downwardly into an inverted V shape in the vehicle 1. Note that the inverted V shape mentioned here includes not only a perfect inverted V shape but also an approximately inverted V shape.

[0072] Incidentally, when the vehicle 1 is rear-ended, not only does the rear frame 24 of the vehicle body 2 bend upwardly of the vehicle 1, but depending on the size of the vehicle 1 and the height position of the bumper, etc., the rear frame 24 of the vehicle body 2 may also bend downwardly of the vehicle 1.

[0073] In this embodiment, the recess 42 is provided so as to open on the underside of the base member 11, so that when a collision load is input to the vehicle body 2 from the rear of the vehicle 1, the base member 11 is caused to break downward of the vehicle 1 by the recess 42. Therefore, even if the vehicle body 2 bends downward of the vehicle 1 when the vehicle 1 is hit from behind, the base member 11 will break along the direction in which the vehicle body 2 bends, and the amount of reduction in the capacity of the luggage compartment 8 is suppressed.

[0074] Fig. 11 is a schematic side view showing the rear of a vehicle equipped with a moving deck module according to a fifth embodiment of the present invention. In Fig. 11, a moving deck module 10D of this embodiment has a rear support part 46 instead of the rear support part 16 in the first embodiment.

[0075] The rear support portion 46 has an inclined portion 47 attached to the rear end portion of the base member 11, and an erected portion 48 connected to the inclined portion 47 and fixed to the rear frame 24 of the vehicle body 2 so as to extend in the vertical direction of the vehicle 1. The inclined portion 47 and the erected portion 48 are fixed to each other by welding or the like.

[0076] The inclined portion 47 is attached by a pin joint or the like near the rear end of the base member 11 so as to incline downward toward the rear side of the vehicle body 2 (the opposite side to the front support portion 15). The base end of the standing portion 48 is fixed by a bolt fastening or the like near the rear end of the rear side member 25 of the rear frame 24. The tip of the standing portion 48 is in contact with the base member 11. The standing portion 48 extends straight in the vertical direction of the vehicle 1 and supports the load from the base member 11.

[0077] In this embodiment, the standing portion 48 of the rear support portion 46 is fixed to the vehicle body 2 so as to extend in the vertical direction of the vehicle 1, and the inclined portion 47 is connected to the standing portion 48, so that the rigidity of the moving deck module 10D is further increased. Therefore, when luggage is placed on the moving deck 12, the load of the luggage can be received in the vertical direction of the vehicle 1 more efficiently.

[0078] 12 is a schematic side view showing the rear of a vehicle equipped with a moving deck module according to a sixth embodiment of the present invention. In FIG. 12, a moving deck module 10E of this embodiment includes a base member 51 and a moving deck 52 instead of the base member 11 and the moving deck 12 of the first embodiment.

[0079] As shown in Fig. 13, the base member 51 has a pair of left and right rails 55 extending in the front-rear direction of the vehicle 1. Each rail 55 has a concave shape. The base member 51 has a base portion 57a ​​and side wall portions 57b, 57b integrated with both left and right edges of the base portion 57a. The concave rail 55 is defined by the upper surface of the base portion 57a ​​and the inner surfaces of the side wall portions 57b, 57b. End wall portions 56 that close the rails 55 are provided at the front and rear ends of the base member 51, respectively.

[0080] The moving deck 52 includes a frame-shaped support 53 and the above-mentioned deck board 14. The support 53 is attached to the base member 51 so as to be movable in the fore-and-aft direction of the vehicle 1. As shown in FIG. 13, the front end portions of the left and right sides of the support 53 are provided with multiple pairs of rollers 59 (two pairs, left and right in this case) that run in the fore-and-aft direction of the vehicle 1 along rails 55 of the base member 51. The rollers 59 are engagement portions that engage with the rails 55 and move along the rails 55. Each roller 59 is supported by support portions 58, 58 provided at the front end portion of the support 53 so as to be freely rotatable. Thus, the support 53 is supported by the base member 51 so as to be movable by the four rollers 59.

[0081] Deck board 14 may also be movably supported by support 53 with four rollers. In this case, for example, concave rails along which the rollers of deck board 14 run are provided on support 53.

[0082] The front support part 15 connects a front end portion of the base member 51 to the rear frame 24 of the vehicle body 2, and supports the base member 51 relative to the vehicle body 2. The rear support part 16 connects a rear end portion of the base member 51 to the rear frame 24, and cooperates with the front support part 15 to support the base member 51 relative to the vehicle body 2. The other structures are similar to those of the first embodiment described above.

[0083] In this embodiment, as in the first embodiment described above, the front support portion 15 and the rear support portion 16 are provided, so that when a collision load is input to the vehicle body 2 from the rear of the vehicle 1, the base member 51 rotates upward of the vehicle 1 relative to the vehicle body 2. This reduces the amount of movement of the base member 51 and the moving deck 52 toward the front of the vehicle 1. This prevents the moving deck module 10E from pushing in the rear seat 9 when the vehicle 1 is hit from behind.

[0084] Fig. 14 is a schematic side view showing the rear of a vehicle equipped with a moving deck module according to the seventh embodiment of the present invention. In Fig. 14, the moving deck module 10F of this embodiment has a rear support part 66 instead of the rear support part 16 in the sixth embodiment.

[0085] The rear support part 66 extends straight in the up-down direction of the vehicle 1. An upper end of the rear support part 66 is fixed to the rear end of the base member 51 by welding or the like. A lower end of the rear support part 66 is fixed to the rear end of the rear side member 25 of the rear frame 24 by bolting or the like. In other words, both ends of the rear support part 66 are rigidly joined to the base member 11 and the rear side member 25, respectively. For this reason, when a collision load is input to the vehicle body 2 from the rear of the vehicle 1, a bending moment is generated in the base member 51.

[0086] In addition, recesses 60 are provided on both the left and right sides of the base member 51 in a portion between the front support portion 15 and the rear support portion 66. The recesses 60 serve as starting points for bending the base member 51 into an inverted V shape due to deformation of the rear frame 24 when a load is input to the rear of the vehicle 1 from the rear of the vehicle 1. At this time, the recesses 60 serve as starting points for bending into an inverted V shape when viewed from the side of the moving deck module 10F. The recesses 60 are provided in the side wall portion 57b (see FIG. 13) of the base member 51. The recesses 60 are provided so as to open on the upper surface of the base member 51. The recesses 60 are, for example, cutouts having a V-shaped cross section.

[0087] The recesses 60 are provided in a position on the base member 51 rearward of the center in the front-rear direction of the vehicle 1. Specifically, the recesses 60 are provided in a position on the base member 51 rearward of each set of rollers 59 when the moving deck 52 is stored in the luggage compartment 8. The recesses 60 are also provided in the base member 51 so that when a load is input to the vehicle body 2 from the rear of the vehicle 1, the moving deck 52 is inclined at an angle relative to the rear frame 24 of the vehicle body 2 so as to fit within the luggage compartment 8 (see FIG. 15).

[0088] In the movable deck module 10F configured as described above, when the movable deck 52 is stored in the luggage compartment 8 and the barrier 30 for a collision test collides with the vehicle 1 from behind as shown in Fig. 15(a), a collision load is input to the rear bumper 5 and the rear frame 24 of the vehicle body 2. Then, the rear frame 24 is pushed forward of the vehicle 1 and deformed.

[0089] 15(b), a bending moment is generated in the base member 51 triggered by the rear support portion 66, so that the base member 51 rotates upward relative to the rear frame 24 via the front support portion 15, and the base member 51 and the moving deck 52 are lifted. In addition, the base member 51 rotates upward relative to the vehicle 1 relative to the vehicle body 2, and the base member 51 is bent into an inverted V shape triggered by the recess 60. However, the moving deck 52 does not bend into an inverted V shape following the base member 51.

[0090] Then, when the rear frame 24 is further pushed forward of the vehicle 1, the barrier 30 enters under the moving deck 52 as shown in Fig. 15(c). Therefore, the base member 51 rotates further upward relative to the rear frame 24, so that the base member 51 and the moving deck 52 are further raised. At this time, the moving deck 52 is kept in a state of being accommodated within the luggage compartment 8.

[0091] In the present embodiment as described above, when the vehicle 1 is rear-ended and a collision load is input to the vehicle body 2 from the rear of the vehicle 1, the vehicle body 2 deforms, causing the base member 51 to rotate upward relative to the vehicle 1 relative to the vehicle body 2, and the base member 51 is bent into an inverted V shape starting from the recess 60. Therefore, the amount of movement of the base member 51 and the moving deck 52 toward the front of the vehicle 1 is further reduced.

[0092] Furthermore, in this embodiment, the recess 60 is provided at a position on the base member 51 rearward of the center of the vehicle 1 in the front-rear direction. Therefore, when the vehicle 1 is rear-ended and a collision load is input to the vehicle body 2 from the rear of the vehicle 1, the amount of rotation of the base member 51 relative to the vehicle body 2 is reduced, and the inclination angle of the moving deck 52 relative to the vehicle body 2 can be made small. This prevents the base member 51 and the moving deck 52 from being lifted too high. Therefore, for example, luggage placed on the moving deck 52 is less likely to deform.

[0093] Furthermore, in this embodiment, the recess 60 is provided at a position on the base member 51 rearward of the sets of rollers 59 when the moving deck 52 is stored in the luggage compartment 8. Therefore, when the vehicle 1 is rear-ended while the moving deck 52 is stored in the luggage compartment 8 and a collision load is input to the vehicle body 2 from the rear of the vehicle 1, the base member 51 bends in an inverted V shape starting from the recess 60, but the moving deck 52 is less likely to bend. Therefore, damage to the moving deck 52 can be suppressed. As a result, for example, it becomes possible to reuse the moving deck 52.

[0094] Furthermore, in this embodiment, even if the vehicle 1 is rear-ended and a collision load is input from the rear of the vehicle 1 to the vehicle body 2, the moving deck 52 is accommodated within the luggage compartment 8, so the moving deck 52 is unlikely to interfere with the vehicle body 2. Therefore, damage to the moving deck 52 can be further suppressed.

[0095] In this embodiment, the rear support part 66 extends straight in the vertical direction of the vehicle 1, but is not limited to this form. For example, the rear support part 66 may extend in an oblique direction relative to the base member 11 and the rear frame 24, as long as it is rigidly joined to the base member 11 and the rear frame 24, respectively.

[0096] Fig. 16 is a schematic side view showing the rear of a vehicle equipped with a moving deck module according to an eighth embodiment of the present invention, together with the operation of the moving deck module. In Fig. 16, the moving deck module 10G of this embodiment includes two left and right intermediate support parts 71 and two left and right connectors 72 (see Fig. 17) in addition to the configuration in the seventh embodiment. Note that the connectors 72 are omitted in Fig. 16 for convenience.

[0097] The intermediate support part 71 is attached to a portion of the rear frame 24 of the vehicle body 2 between the front support part 15 and the rear support part 66. The intermediate support part 71 is fixed to the rear side member 25 of the rear frame 24 by bolting or the like. The intermediate support part 71 cooperates with the front support part 15 and the rear support part 66 to form a third support part that supports the base member 51 relative to the vehicle body 2. The intermediate support part 71 extends straight in the up-down direction of the vehicle 1. The intermediate support part 71 is located directly below the recess 60 of the base member 51.

[0098] As shown in Fig. 17, the connector 72 detachably connects the base member 51 and the intermediate support portion 71. As shown in Figs. 17 to 19, the connector 72 has a crank-shaped connector 73 fixed to the base member 51, and a J-shaped pressing member 74 fixed to the intermediate support portion 71 and pressing the connector 73 against the intermediate support portion 71. Both the connector 73 and the pressing member 74 are formed of a metal plate.

[0099] The connecting member 73 is fixed to the lower surface of the base member 51 by welding or the like. The pressing member 74 is fixed to the upper end surface of the intermediate support part 71 by welding or the like. The pressing member 74 has a base part 74a fixed to the intermediate support part 71 and a locking part 74b which cooperates with the base part 74a to sandwich the connecting member 73. The connecting member 73 is pressed against the intermediate support part 71 by the base part 74a and the locking part 74b sandwiching the connecting member 73 between them. This brings the base member 51 and the intermediate support part 71 into a connected state (see FIG. 17(a)).

[0100] In the movable deck module 10G as described above, as shown in Fig. 16(a), when a collision test barrier 30 collides with the vehicle 1 from behind, a collision load is input to the rear bumper 5 and the rear frame 24. Then, as shown in Fig. 16(b), the base member 51 rotates upward relative to the rear frame 24, so that the base member 51 and the movable deck 52 are lifted and the base member 51 is bent in an inverted V shape starting from the recess 60.

[0101] 17(b) and 18, the locking portion 74b of the pressing member 74 is pressed upward by the connecting member 73, so that the locking portion 74b is plastically deformed and the connecting member 73 comes out from between the base portion 74a and the locking portion 74b, and the connection between the base member 51 and the intermediate support portion 71 is released. Therefore, even with the connecting tool 72, the base member 51 is smoothly bent into an inverted V shape.

[0102] In the present embodiment as described above, the base member 51 is supported relative to the vehicle body 2 by the front support parts 15, the rear support parts 66, and the intermediate support parts 71, so that the rigidity of the moving deck module 10G is further increased. Therefore, when luggage is placed on the moving deck 52, the load of the luggage can be received more efficiently in the vertical direction of the vehicle 1. Furthermore, when the vehicle 1 is rear-ended and a collision load is input to the vehicle body 2 from the rear of the vehicle 1, the connection between the base member 51 and the intermediate support parts 71 by the connector 72 is released, so that bending of the base member 51 triggered by the recess 60 is not hindered.

[0103] Furthermore, in this embodiment, the intermediate support part 71 is located directly below the recessed part 60 of the base member 51. Therefore, the intermediate support part 71 effectively suppresses the decrease in rigidity of the moving deck module 10G caused by providing the recessed part 60 in the base member 51. Therefore, even if heavy luggage is placed on the moving deck 52, the load of the luggage can be sufficiently received in the vertical direction of the vehicle 1.

[0104] In this embodiment, in a normal state, the pressing member 74 presses the connecting member 73 against the intermediate support portion 71, thereby connecting the base member 51 and the intermediate support portion 71. When a collision load is input to the vehicle body 2 from the rear of the vehicle 1, the base member 51 bends in an inverted V shape, causing the connecting member 73 to come out of the pressing member 74, and the connection between the base member 51 and the intermediate support portion 71 is released. In this way, the connecting device 72 can be realized with a simple structure.

[0105] In this embodiment, the intermediate support portion 71 is located directly below the recessed portion 60 of the base member 51, but is not limited to this. The intermediate support portion 71 may be disposed at a position shifted in the front-rear direction of the vehicle 1 with respect to the recessed portion 60 of the base member 51.

[0106] 20 is a schematic side view showing the rear of a vehicle equipped with a moving deck module according to the ninth embodiment of the present invention, together with the operation of the moving deck module. In FIG. 20, the moving deck module 10H of this embodiment includes a base member 81 and a moving deck 82, instead of the base member 51 and the moving deck 52 in the seventh embodiment.

[0107] Support parts 85 are provided at the rear end portions on both the left and right sides of the base member 81. Left and right pairs of rollers 86 (two pairs in this case) are supported so as to be freely rotatable on each support part 85. The base member 81 is also provided with the recesses 60 described above. When the movable deck 82 is stored in the luggage compartment 8, the recesses 60 are provided in front of each pair of rollers 86 on the base member 81.

[0108] The moving deck 82 includes a frame-shaped support 83 and the above-mentioned deck board 14. The support 83 is attached to the base member 81 so as to be movable in the fore-and-aft direction of the vehicle 1. The support 83 has a pair of left and right rails 87 extending in the fore-and-aft direction of the vehicle 1. Each roller 86 of the base member 81 runs relatively along the rails 87. The rollers 86 are engagement parts that engage with the rails 87 and move relatively along the rails 87. Thus, the support 83 is movably supported by the base member 81 by the four rollers 86.

[0109] Moreover, the moving deck module 10H includes a front support portion 88 and the rear support portion 36 in the second embodiment, instead of the front support portion 15 and the rear support portion 66 in the seventh embodiment.

[0110] The front support part 88 connects the front end portion of the base member 81 and the rear frame 24 of the vehicle body 2. One end of the front support part 88 is fixed to the front end portion of the base member 81 by welding or the like. The other end of the front support part 88 is fixed to the front end portion of the rear side member 25 of the rear frame 24 by bolt fastening or the like. In other words, both ends of the front support part 88 are rigidly joined to the base member 81 and the rear side member 25, respectively. For this reason, when a collision load is input to the vehicle body 2 from the rear of the vehicle 1, a bending moment is generated in the base member 81.

[0111] In the movable deck module 10H described above, when a collision test barrier 30 collides with the vehicle 1 from behind, the rear bumper 5 and the rear frame 24 are pushed forward of the vehicle 1 and deformed, as shown in Fig. 20(a). Then, as shown in Fig. 20(b), the base member 81 rotates upward relative to the rear frame 24 via the rear support portion 36, and the base member 81 and the movable deck 82 are lifted, and the base member 81 is bent into an inverted V shape starting from the recess 60.

[0112] In this manner, also in this embodiment, as in the above-described seventh embodiment, when the vehicle 1 is rear-ended and a collision load is input to the vehicle body 2 from the rear of the vehicle 1, the base member 81 rotates upward relative to the vehicle body 2 due to deformation of the vehicle body 2, and the base member 81 is bent in an inverted V shape starting from the recess 60. Therefore, the amount of movement of the base member 81 and the moving deck 82 toward the front of the vehicle 1 is further reduced.

[0113] Although several embodiments of the present invention have been described above, the present invention is not limited to the above-mentioned embodiments. For example, when a recess is provided in the base member as a starting point of folding, the appropriate position of the recess varies depending on the type, dimensions, specifications, etc. of the vehicle, and therefore can be changed in various ways depending on the vehicle.

[0114] In addition, the front support part or the rear support part may be rotatably attached to the vehicle body 2 via the shaft part so that when a load is input to the vehicle body 2 from the rear of the vehicle 1, the deformation of the vehicle body 2 allows the base member to rotate in the vertical direction of the vehicle 1 relative to the vehicle body 2.

[0115] Also, in the above embodiment, the moving deck is made up of two parts, a support and a deck board, and the support is attached to the base member so as to be movable in the fore-and-aft direction of the vehicle 1, and the deck board is attached to the support so as to be movable in the fore-and-aft direction of the vehicle 1, but this is not particularly limited to such an embodiment. For example, the deck board may be structured so as not to move in the fore-and-aft direction of the vehicle 1 relative to the support.
