Description

[Technical field]

[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 mounted in a luggage compartment located at the rear of a vehicle, the module comprising a base fixed to the body of the vehicle, a deck frame located on the base and movable in the fore-and-aft direction of the vehicle relative to the base, and a deck board located on the deck frame, the deck frame receiving the load of the deck board from above the vehicle and having a structure such that its length in the fore-and-aft direction is shortened when a load is input from the rear of the vehicle.

[0007] In such a moving deck module, when a collision load is input from the rear of the vehicle due to a rear-end collision of the vehicle, the base and deck board are deformed. However, since the deck frame has a function of supporting the deck board, it cannot be structured so as to be easily deformed or broken. Therefore, the deck frame is structured so that it receives the load of the deck board from above the vehicle and shortens its length in the front-rear direction when a load is input from the rear of the vehicle. Therefore, when a collision load is input to the moving deck module, the base and deck board are deformed and the length of the deck frame in the front-rear direction is shortened. Therefore, the amount of movement of the moving deck module toward the front of the vehicle is reduced. This prevents the moving deck module from pushing in the rear seats when the vehicle is rear-ended.

[0008] The deck frame may have a first frame member attached to the base so as to be movable in the fore-and-aft direction, and a second frame member supported by the first frame member so as to be slidable in the fore-and-aft direction. In this configuration, when a collision load is input to the deck frame from the rear of the vehicle, the second frame member slides in the fore-and-aft direction relative to the first frame member, shortening the fore-and-aft length of the deck frame. This makes it easier to design a deck frame structure that receives the deck board load from above the vehicle and shortens its fore-and-aft length when a load is input from the rear of the vehicle.

[0009] The first frame member may have a pair of left and right cylindrical portions extending in the front-rear direction, and the second frame member may have a pair of left and right sliding portions extending in the front-rear direction and housed in the cylindrical portions, the sliding portions being slidable relative to the cylindrical portions while housed in the cylindrical portions. In this configuration, when a collision load is input to the deck frame from the rear of the vehicle, the sliding portions of the second frame member slide relative to the cylindrical portions within the cylindrical portions of the first frame member, shortening the front-rear length of the deck frame. Therefore, the second frame member can be easily slid in the front-rear direction relative to the first frame member.

[0010] An energy absorbing material may be disposed inside the cylindrical portion to absorb energy generated when a load is input from the rear of the vehicle. In this configuration, when a collision load is input to the deck frame from the rear of the vehicle, the sliding portion slides against the cylindrical portion inside the cylindrical portion. At this time, the energy of the collision load generated inside the cylindrical portion is absorbed by the energy absorbing material. Therefore, the amount of penetration of the colliding object into the vehicle is reduced.

[0011] The sliding portion may be held by the cylindrical portion so as to be slidable in the front-rear direction by frictional resistance. In such a configuration, the sliding portion is normally held by the cylindrical portion by frictional resistance. Therefore, the holding position of the second frame member relative to the first frame member can be set by a simple structure.

[0012] The base may be provided with a recess that becomes the starting point of the base breaking when a load is input from the rear of the vehicle. In this configuration, when a collision load is input to the base from the rear of the vehicle, the base breaks starting from the recess, and the length of the deck frame in the front-rear direction is shortened. This further reduces the amount of movement of the deck module toward the front of the vehicle.

[0013] The deck board may be provided with a groove that serves as a starting point for the deck board to break when a load is input from the rear of the vehicle. In this configuration, when a collision load is input to the deck board from the rear of the vehicle, the deck board breaks starting from the groove, and the length of the deck frame in the front-to-rear direction is shortened. This further reduces the amount of movement of the deck module toward the front of the vehicle. Effect of the Invention

[0014] 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]

[0016] 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.

[0017] Fig. 1 is a schematic perspective view showing the rear of a vehicle equipped with a movable deck module according to one 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 panels 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 (see Fig. 2).

[0018] A luggage compartment 8 in which luggage 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. A movable deck module 10 of the present embodiment is mounted in the luggage compartment 8.

[0019] Fig. 2 is a schematic side view showing the rear of the vehicle 1 equipped with the moving deck module 10. Fig. 3 is a partial cross-sectional view of the moving deck module 10. Fig. 4 is an exploded perspective view of the moving deck module 10.

[0020] 2 to 4, the movable deck module 10 comprises a frame-shaped base 11, a deck frame 12 arranged on this base 11 and movable in the fore-and-aft direction of the vehicle 1 relative to the base 11 (hereinafter simply referred to as the fore-and-aft direction), and a deck board 13 arranged on this deck frame 12.

[0021] The base 11 is fixed to a rear frame 16 of the vehicle body 2 via a pair of left and right front support parts 14 and a pair of left and right rear support parts 15. The front support parts 14 and the rear support parts 15 support the base 11 with respect to the vehicle body 2.

[0022] The rear frame 16 has a pair of left and right rear side members 17 extending in the front-rear direction, a rear cross member 18 extending in the vehicle width direction, which is the left-right direction of the vehicle 1, and connecting the rear side members 17 to each other, and a rear reinforcement 19 extending in the vehicle width direction and connecting the rear side members 17 to each other behind the rear cross member 18. In addition, a bumper reinforcement 20 extending in the vehicle width direction is disposed behind the rear side members 17.

[0023] The front support part 14 connects the base 11 and the rear side member 17. The rear support part 15 connects the base 11 and the rear side member 17 on the rear side of the front support part 14. The base 11 and the rear support part 15 are connected via an inclined part 22. The inclined part 22 is inclined downward from the base 11 to the rear support part 15 toward the rear side of the vehicle body 2.

[0024] The base 11 has a pair of left and right concave rails 23 extending in the front-rear direction. The base 11 has a base portion 24a and side walls 24b, 24b integrated with the base portion 24a. The concave rails 23 are defined by the upper surface of the base portion 24a and the inner surfaces of the side walls 24b, 24b. End walls 25 that close the concave rails 23 are provided at the front and rear ends of the base 11, respectively.

[0025] The base 11 is provided with recesses 26 on both the left and right sides, which are the starting points for the base 11 to break when a load is input from the rear of the vehicle 1. The recesses 26 are located rearward of the center of the base 11 in the front-to-rear direction. The recesses 26 are provided in the side wall 24b (see FIG. 4) of the base 11. The recesses 26 open to the top surface of the base 11. The recesses 26 have, for example, a V-shaped cross section. The location of the recesses 26 is not limited to being rearward of the center of the base 11 in the front-to-rear direction.

[0026] Deck frame 12 supports deck board 13. Deck frame 12 receives the load of deck board 13 from above vehicle 1, and has a structure such that its length in the front-to-rear direction is shortened when a load is input from the rear of vehicle 1 (see FIG. 7).

[0027] The deck frame 12 has a U-shaped front frame member 30 (first frame member) and a U-shaped rear frame member 31 (second frame member) disposed on the rear side of the vehicle 1 relative to the front frame member 30. The deck frame 12 is made of a metal material such as stainless steel or aluminum.

[0028] The front frame member 30 is attached to the base 11 so as to be movable in the front-rear direction. The front frame member 30 has a pair of left and right tubular portions 32 extending in the front-rear direction, and a rod-shaped connecting portion 33 that connects the front ends of these tubular portions 32. The front frame member 30 has a strength sufficient to withstand the load from the deck board 13. In other words, the front frame member 30 has a structure that is strong against loads applied in the vertical direction.

[0029] As shown in Fig. 5, the cylindrical portion 32 has a square cylindrical shape (rectangular in cross section). The front end of the cylindrical portion 32 may be open or closed. The front end portion of the cylindrical portion 32 is provided with a plurality of left and right sets of rollers 34 (two sets in this case) that run in the front-rear direction along the concave rail 23 of the base 11. Each roller 34 is supported by support portions 35, 35 protruding from the lower surface of the cylindrical portion 32 so as to be freely rotatable. Therefore, the front frame member 30 is supported by the four rollers 34 so as to be movable on the base 11.

[0030] The rear frame member 31 is supported by the front frame member 30 so as to be slidable in the front-rear direction. The rear frame member 31 has a pair of left and right sliding portions 36 extending in the front-rear direction, and a rod-shaped connecting portion 37 connecting the rear ends of these sliding portions 36 to each other.

[0031] As shown in Fig. 5, the sliding part 36 has a square cylindrical shape (rectangular cross section) similar to the above-mentioned cylindrical part 32. The rear end of the sliding part 36 may be open or closed. The outer dimensions of the sliding part 36 are smaller than the outer dimensions of the cylindrical part 32. The sliding part 36 is slidable relative to the cylindrical part 32 while being housed within the cylindrical part 32. The sliding part 36 may have a square prism shape.

[0032] A plurality of leaf springs 38 that bias the sliding portion 36 are attached to the inner wall surface of the cylindrical portion 32. This allows the sliding portion 36 to slide in the front-rear direction by frictional resistance relative to the cylindrical portion 32. The leaf springs 38 may be attached to the outer wall surface of the sliding portion 36 and bias the sliding portion 36 toward the cylindrical portion 32.

[0033] 6(a), such deck frame 12 is normally in an extended state in which sliding portion 36 of rear frame member 31 is pulled out a predetermined length from within cylindrical portion 32 of front frame member 30. At this time, the length of deck frame 12 in the front-to-rear direction is L1. In addition, the position of rear frame member 31 relative to front frame member 30 is maintained by the biasing force of leaf spring 38.

[0034] In this normal state, when a load is input to the deck frame 12 from the rear of the vehicle 1, as shown in FIG. 6(b), the sliding portion 36 of the rear frame member 31 slides in the front-rear direction within the tubular portion 32 of the front frame member 30 against the biasing force of the leaf spring 38, causing the deck frame 12 to contract. At this time, the length of the deck frame 12 in the front-rear direction is L2 ( <L1)である。

[0035] The deck board 13 is fixed to an upper surface of the front frame member 30 of the deck frame 12. Luggage is placed on the deck board 13. The deck board 13 has a flat plate shape. The deck board 13 is made of, for example, resin.

[0036] Deck board 13 is provided with a groove 40 that serves as a starting point for deck board 13 to break when a load is input from the rear of vehicle 1. Groove 40 is located at a position rearward of the center of deck board 13 in the front-to-rear direction. Groove 40 is located at a position corresponding to recess 26 of base 11. Groove 40 extends in the vehicle width direction. Groove 40 opens to the lower surface of deck board 13. Groove 40 has, for example, a V-shaped cross section. Note that the location of groove 40 is not limited to being rearward of the center of deck board 13 in the front-to-rear direction.

[0037] In addition, although not specifically shown, the movable deck module 10 is equipped with a mechanism for locking the deck frame 12 to the base 11 when the deck frame 12 and the deck board 13 are stored in the luggage compartment 8 and when the deck frame 12 and the deck board 13 are pulled out rearward from the luggage compartment 8.

[0038] In the moving deck module 10 configured as described above, when a collision test barrier 41 collides with the vehicle 1 from behind, as shown in FIG. 7(a), a collision load is input to the rear bumper 5 and the vehicle body 2.

[0039] 7(b), the movable deck module 10 is pushed forward of the vehicle 1 together with the rear frame 16 and deformed. At this time, the recessed portion 26 of the base 11 triggers the base 11 to bend, and the groove portion 40 of the deck board 13 triggers the deck board 13 to bend. In addition, the sliding portion 36 of the rear frame member 31 slides forward of the vehicle 1 against the cylindrical portion 32 of the front frame member 30, thereby shortening the length of the deck frame 12 in the front-to-rear direction.

[0040] Fig. 8 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. Fig. 9 is an exploded perspective view of the moving deck module shown in Fig. 8.

[0041] 8 and 9, the movable deck module 100 of this comparative example comprises a frame-shaped base 101, a deck frame 102 arranged on this base 101 and movable in the forward and backward directions relative to the base 101, and a deck board 103 arranged on this deck frame 102.

[0042] The base 101 is not provided with the recess 26 described above. The deck frame 102 is composed of a single frame-shaped member. Like the deck frame 12 described above, the deck frame 102 has two sets of rollers 34, and is attached to the base 101 so as to be movable in the front-rear direction. The deck board 103 is fixed to the upper surface of the deck frame 102. The deck board 103 is not provided with the groove portion 40 described above.

[0043] 8, in this comparative example, when the barrier 41 collides with the vehicle 1 from behind, the rear frame 16 is pushed forward of the vehicle 1 and deformed. The moving deck module 100 is also pushed forward of the vehicle 1, but if the deformation of the moving deck module 100 is small, the moving deck module 100 will hit the rear seat 9 and push the rear seat 9 in.

[0044] In response to such a problem, in this embodiment, when the vehicle 1 is rear-ended and a collision load is input from the rear of the vehicle 1, the base 11 and the deck board 13 are deformed. However, since the deck frame 12 has a function of supporting the deck board 13, it cannot be structured to be easily deformed or broken. Therefore, the deck frame 12 is structured to receive the load of the deck board 13 from above the vehicle 1 and to shorten its length in the front-rear direction when a load is input from the rear of the vehicle 1. Therefore, when a collision load is input to the moving deck module 10, the base 11 and the deck board 13 are deformed and the length of the deck frame 12 in the front-rear direction is shortened. Therefore, the amount of movement of the moving deck module 10 toward the front of the vehicle 1 is reduced. This prevents the moving deck module 10 from pushing in the rear seat 9 when the vehicle 1 is rear-ended.

[0045] Furthermore, in this embodiment, when a collision load is input to the deck frame 12 from the rear of the vehicle 1, the rear frame member 31 slides in the fore-and-aft direction relative to the front frame member 30, shortening the fore-and-aft length of the deck frame 12. This makes it easier to design a structure for deck frame 12 that receives the load of the deck board 13 from above the vehicle 1 and also shortens its fore-and-aft length when a load is input from the rear of the vehicle 1.

[0046] Furthermore, in this embodiment, when a collision load is input to the deck frame 12 from the rear of the vehicle 1, the sliding portion 36 of the rear frame member 31 slides relative to the cylindrical portion 32 of the front frame member 30 within the cylindrical portion 32, shortening the length of the deck frame 12 in the front-to-rear direction. Therefore, the rear frame member 31 can be easily slid relative to the front frame member 30 in the front-to-rear direction.

[0047] Furthermore, in this embodiment, under normal circumstances, the sliding portion 36 is held by the cylindrical portion 32 due to frictional resistance. Therefore, the holding position of the rear frame member 31 relative to the front frame member 30 can be set with a simple structure.

[0048] In this embodiment, when a collision load is input to the base 11 from the rear of the vehicle 1, the base 11 breaks at the recess 26 of the base 11, and the length of the deck frame 12 in the front-rear direction is shortened. Therefore, the amount of movement of the moving deck module 10 toward the front of the vehicle 1 is further reduced.

[0049] Furthermore, in this embodiment, when a collision load is input to deck board 13 from the rear of vehicle 1, deck board 13 breaks at groove portion 40 of deck board 13, and the length of deck frame 12 in the front-to-rear direction is shortened. As a result, the amount of movement of moving deck module 10 toward the front of vehicle 1 is further reduced.

[0050] In this embodiment, the base 11 and the rear support part 15 are connected via an inclined part 22 that inclines downward toward the rear side of the vehicle 1. For this reason, when a collision load is input to the vehicle body 2 from the rear of the vehicle 1, this may trigger the base 11 to break together with the recessed part 26. Therefore, the base 11 becomes even more likely to break.

[0051] Fig. 10 is a plan view including a partial cross section of a deck frame of a moving deck module according to another embodiment of the present invention. In Fig. 10, the moving deck module 10 of this embodiment includes a deck frame 12 having a front frame member 30 and a rear frame member 31, similar to the above embodiment.

[0052] An energy absorbing material 45 (EA material) is disposed inside the cylindrical portion 32 of the front frame member 30. The energy absorbing material 45 is a material that absorbs energy generated inside the cylindrical portion 32 when a load is input to the deck frame 12 from the rear of the vehicle 1. As the energy absorbing material 45, for example, polystyrene foam, mesh metal, or resin mixed with a foaming agent, etc., is used.

[0053] In this embodiment, when a collision load is input to the deck frame 12 from the rear of the vehicle 1, the sliding portion 36 slides against the cylindrical portion 32 inside the cylindrical portion 32. At this time, the energy of the collision load generated inside the cylindrical portion 32 is absorbed by the energy absorbing material 45. Therefore, the amount of intrusion of the barrier 41 (collision object) into the vehicle 1 is reduced.

[0054] Figure 11 is a perspective view showing a modified example of the deck frame shown in Figure 6. In Figure 11, deck frame 12A of this modified example has a U-shaped rear frame member 50 (first frame member) and a U-shaped front frame member 51 (second frame member) arranged on the front side of vehicle 1 with respect to rear frame member 50.

[0055] The rear frame member 50 is attached to the base 11 so as to be movable in the front-rear direction. The rear frame member 50 has a pair of left and right tubular portions 52 extending in the front-rear direction, and a connecting portion 53 connecting the rear ends of these tubular portions 52. The front end portion of the tubular portion 52 is provided with multiple left and right sets of rollers 54 (here, two sets) that run in the front-rear direction along the concave rail 23 of the base 11.

[0056] The front frame member 51 is supported by the rear frame member 50 so as to be slidable in the front-rear direction. The front frame member 51 has a pair of left and right sliding portions 55 extending in the front-rear direction, and a connecting portion 56 connecting front ends of these sliding portions 55. The sliding portions 55 are slidable relative to the cylindrical portion 52 while being housed within the cylindrical portion 52.

[0057] A plurality of leaf springs 38 (see FIG. 5) that bias the sliding portion 55 are attached to the inner wall surface of the cylindrical portion 52. This allows the sliding portion 55 to be held slidably in the front-rear direction relative to the cylindrical portion 52 by frictional resistance.

[0058] 11(a), such deck frame 12A is normally in an extended state in which sliding portion 55 of front frame member 51 is pulled out a predetermined length from within cylindrical portion 52 of rear frame member 50. When a load is input to deck frame 12A from the rear of vehicle 1 in this normal state, cylindrical portion 52 of rear frame member 50 moves relatively toward the front of vehicle 1 with respect to sliding portion 55 of front frame member 51, causing deck frame 12A to enter a contracted state, as shown in FIG.

[0059] Figure 12 is a plan view showing another modified example of the deck frame shown in Figure 6. In Figure 12, deck frame 12B of this modified example has a U-shaped front frame portion 60, a U-shaped rear frame portion 61 arranged on the rear side of this front frame portion 60, and a pair of left and right connecting portions 62 arranged between front frame portion 60 and rear frame portion 61.

[0060] The front frame portion 60, the rear frame portion 61 and the connection portion 62 are integrally formed. The dimension of the front frame portion 60 in the vehicle width direction (left and right direction) is greater than the dimension of the rear frame portion 61 in the vehicle width direction. The connection portion 62 connects the rear end of the front frame portion 60 and the front end of the rear frame portion 61.

[0061] When a load is input to such deck frame 12B from the rear of the vehicle 1, as shown in Fig. 12(b), the portion of deck frame 12B including connection portion 62 undergoes plastic deformation, shortening the length of deck frame 12B in the front-to-rear direction. At this time, the energy of the load is absorbed by the plastic deformation of connection portion 62, preventing deck frame 12B from breaking and flying apart.

[0062] Fig. 13 is a plan view showing yet another modified example of the deck frame shown in Fig. 6. In Fig. 13, the deck frame 12C of this modified example has a U-shaped front frame portion 65 and a U-shaped rear frame portion 66 arranged rearward of the front frame portion 65. The dimension of the front frame portion 65 in the vehicle width direction is greater than the dimension of the rear frame portion 66 in the vehicle width direction. The rear end portion of the front frame portion 65 and the front end portion of the rear frame portion 66 are integrally connected.

[0063] When a load is input from the rear of the vehicle 1 to such deck frame 12C, the connection between the front frame portion 65 and the rear frame portion 66 breaks, and the rear frame portion 66 moves forward, as shown in Fig. 13(b). This shortens the length of the deck frame 12C in the front-to-rear direction.

[0064] The present invention is not limited to the above embodiment. For example, in the above embodiment, base 11 is provided with recess 26 that serves as a starting point for base 11 to bend when a load is input from the rear of vehicle 1, but such recess 26 does not necessarily have to be provided. Also, deck board 13 is provided with groove 40 that serves as a starting point for deck board 13 to bend when a load is input from the rear of vehicle 1, but such groove 40 does not necessarily have to be provided.

[0065] In addition, in the above embodiment, the base 11 is fixed to the vehicle body 2 via the front support portion 14 and the rear support portion 15, but this is not particularly limited to the embodiment, and an intermediate support portion may be additionally disposed between the front support portion 14 and the rear support portion 15. In this case, a connector may be provided that detachably connects the base 11 and the intermediate support portion.

[0066] Also, in the above embodiment, the sliding portion 36 of the rear frame member 31 is held slidably in the front-rear direction relative to the tubular portion 32 of the front frame member 30 by frictional resistance, but this is not particularly limited to such a configuration. As long as the rear frame member 31 is slidable in the front-rear direction relative to the front frame member 30 when a load is input from the rear of the vehicle 1 to the deck frame 12, for example, a locking device or the like for locking the front frame member 30 and the rear frame member 31 together may be provided.

[0067] In addition, in the above embodiment, the rollers 34 of the deck frame 12 run along the concave rails 23 of the base 11, thereby allowing the deck frame 12 to move in the front-to-rear direction relative to the base 11; however, this is not particularly limited to this form, and the sliding bodies of the deck frame 12 may slide along the concave rails 23 of the base 11, thereby allowing the deck frame 12 to move in the front-to-rear direction relative to the base 11.

[0068] Further, in the above embodiment, the deck board 13 is fixed to the deck frame 12, but this is not particularly limited to the embodiment, and the deck board may be attached so as to be movable in the front-rear direction relative to the deck frame. [Explanation of symbols]
