Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a rear compartment structure in a vehicle such as a pickup truck.
[0002]
[Prior art]
In some pickup trucks, a rear portion of the vehicle interior, that is, a space behind the front seat is used as a luggage compartment and an auxiliary seat is provided so that a person can be temporarily placed. This is commonly referred to as an extended cab. Conventionally, this type of rear passenger compartment structure is as follows.
[0003]
That is, as shown in FIG. 6, the rear compartment 51 is divided into a floor portion and a rear portion by a floor panel 52 and a back panel 53 which are parts of the vehicle body, and a predetermined height is formed at the rear end portion of the floor panel 52. Step 54 is formed, and a sheet 55 is provided on the step 54. The seat 55 includes a seat cushion 56 placed on the step 54 and a seat back 57 fixed to the back panel 53, and the rear end of the seat cushion 56 is rotatable to the step 54 by a hinge 58. Connected.
[0004]
In this case, the occupant sits on the seat cushion 56 and leans against the seat back 57 and uses the space in front of the step 54 as a foot space. When a person does not get on, the seat cushion 56 is rotated backward as shown by the phantom line and is erected along the back panel 53. As a result, the seat cushion 56 is cleared rearward, and the rear passenger compartment 51 can be used as a luggage compartment.
[0005]
In this case, the height of the step 54 is relatively high, and a sufficient foot space can be secured only by providing the seat cushion 56 on the step 54. In the first place, the step 54 is provided for layout reasons. For example, in this example, a fuel tank (not shown) is stored and disposed under the step 54. However, since it is preferable that the passenger compartment is as wide as possible, the step 54 should be as low or as low as possible.
[0006]
The floor panel 52 is provided with a center tunnel 59 in the center of the vehicle compartment width. This is also provided for layout reasons, that is, a propeller shaft (not shown) is stored and disposed below the center tunnel 59. In this example, the height of the step 54 and the center tunnel 59 are made equal to stabilize the load when the baggage compartment is used.
[0007]
FIG. 7 shows another example. In addition, the same code | symbol is attached | subjected to the same part. In this example, the level difference 54 is set lower than the previous example. The rear end of the seat cushion 56 is pivotally connected by a hinge 61 to a support bracket 60 that stands at the rear end of the step 54. As a result, the seat cushion 56 can be flipped up and raised along the back panel 53 as in the previous example.
[0008]
In addition, in order to support the weight of an occupant seated on the seat cushion 56, an auxiliary stay 62 is provided that bridges the upper end of the support bracket 60 and the step 54 obliquely. This is to support the seating load by the auxiliary stay 62 at a position in front of the hinge 61 because the seat cushion 56 is completely cantilevered with the support bracket 60 alone.
[0009]
Although not shown in the drawings, in both examples, the sheets 55 are provided on the left and right sides of the center. Of course, it can be provided on either the left or right side.
[0010]
[Problems to be solved by the invention]
By the way, the above structure has the following drawbacks. First, in the case of the former (FIG. 6), when used as a luggage compartment, the high step 54 still exists and the floor is not flat. For this reason, there is a drawback in that the loadability is poor, such as being unstable when loading a large load. Moreover, in order to raise the seating position to such an extent that the occupant does not suffer, a somewhat high step 54 is required, and there is a disadvantage that the space in the vehicle interior is narrowed.
[0011]
In the latter example (FIG. 7), even if the auxiliary stay 62 is provided, the seat cushion 56 is still in a state of being almost cantilevered. Therefore, the support bracket 60, the auxiliary stay 62, and thus the seat cushion 56 must have high rigidity, and there is a disadvantage that the weight and cost increase. Further, since the support bracket 60 and the auxiliary stay 62 protrude in the passenger compartment even when the seat cushion 56 is flipped up backward, the loadability of the luggage is poor and the space efficiency is also poor. Furthermore, the height of the step 54, the foot floor 63 in front of it, and the center tunnel 59 are not all the same, and when used as a luggage compartment, the floor surface becomes stepped and the loadability is poor.
[0012]
SUMMARY OF THE INVENTION Therefore, an object of the present invention is to solve the above-mentioned drawbacks, to flatten the floor surface when used as a luggage compartment, to improve the loadability, and to reduce the level difference to expand the interior space of the vehicle interior. To provide a structure. It is another object of the present invention to provide a rear compartment structure that does not require a highly rigid bracket or the like and can suppress weight and cost.
[0013]
[Means for Solving the Problems]
The present invention provides a rear compartment structure in which a floor portion and a rear portion are partitioned by a floor panel and a back panel, a step having a predetermined height is formed at a rear end portion of the floor panel, and a seat is provided on the step. The seat is placed on the step and the front end is pivotally connected to the vehicle body side, and is moved to the lower floor surface in front of the step by a forward turning operation so that the floor is flat with the step. A storage box that forms a surface, and when the storage box is mounted on the step , the storage box is mounted on the storage box , and the rear end is pivotally connected to the vehicle body side to rotate backward. The storage box comprises an opening / closing means that can be opened and closed with its upper surface openable and closable. Contained items contained above And it forms the shape of a box body forming a closed space to prevent splashing.
[0014]
ADVANTAGE OF THE INVENTION According to this invention, when using as a luggage compartment, a flat floor surface can be formed with the back surface and level | step difference of a storage box, and stackability can be improved. In addition, the height difference of the storage box can be lowered, and the vehicle interior space can be expanded. Since the storage box and the seat cushion are stacked in two stages and supported in a mounted state, a high-rigidity bracket, a seat cushion, and the like are not required, and weight and cost can be suppressed.
[0015]
Here, it is preferable that the storage box is formed at a height equal to the step.
[0016]
Moreover, it is preferable that a center tunnel having a height equal to the step is formed on the floor panel.
[0017]
Moreover, it is preferable that the said storage box consists of the main body by which the upper surface was open | released, and the cover board which block | closes the upper open part of this main body so that opening and closing is possible.
[0018]
Moreover, it is preferable that a seat back is fixed to the back panel.
[0019]
DETAILED DESCRIPTION OF THE INVENTION
Preferred embodiments of the present invention will be described below in detail with reference to the accompanying drawings.
[0020]
FIG. 5 shows a vehicle to which the present invention is applied. This vehicle is a pickup truck. In the front part (front compartment) of the passenger compartment, a solid front seat 1 is provided on the driver's seat side and the passenger seat side so that the occupant can endure long distance travel. The rear part of the passenger compartment (rear passenger compartment 2) is basically used as a luggage compartment, but an auxiliary and simple seat 8 is provided for temporarily carrying a person. This is a so-called extended cab configuration. Here, the sheets 8 are provided on both the left and right sides, but any one of them can be used.
[0021]
As shown in FIGS. 1, 4, and 5, the rear compartment 2 is divided into a floor portion and a rear portion by a floor panel 5 and a back panel 6 that are a part of the vehicle body 4. The back panel 6 stands up in a substantially vertical direction. A step 7 having a predetermined height H is formed at the rear end of the floor panel 5, and a sheet 8 is provided on the step 7. The step 7 continues to the back panel 6 with a constant height. A low floor, that is, a foot floor 9 is formed in front of the step 7, and an occupant seated on the seat 8 puts his / her foot on the foot floor 9. Thus, a foot space is created on the foot floor 9. A center tunnel 10 having the same height as the step 7 is formed on the floor panel 5. As in the prior art, a fuel tank (not shown) is stored below the step 7, and a propeller shaft (not shown) is stored below the center tunnel 10. If limited to the step 7 and the center tunnel 10, a flat and horizontal floor surface is formed by these, and it becomes easy to stably load a large load (for example, a television or a refrigerator).
[0022]
In particular, the seat 8 includes a storage box 11 placed on the step 7, a seat cushion 12 placed and stacked on the storage box 11, and a seat back 13 fixed to the back panel 6. The storage box 11 has a front end and a lower end that are pivotally connected to a front end and an upper end of the step 7 by a hinge 14. The storage box 11 has the same height H as the step 7, and the front surface of the storage box 11 is substantially flush with the front surface of the step 7.
[0023]
As shown in FIG. 3, the storage box 11 includes a main body 15 having an open upper surface and a cover plate 17 that closes an upper open portion 16 of the main body 15 so as to be freely opened and closed. The storage box 11 can be used to store various small items such as tools. The main body 15 is a rectangular box with a bottom, and the cover plate 17 is used to prevent the internal contents from coming out when the storage box 11 is rotated. The main body 15 and the cover plate 17 are an integral injection-molded product made of plastic or resin. The lid plate 17 is fitted into the upper edge portion of the main body 15, and the lid plate 17 is placed on the shelf portion 18 in the main body 15. At this time, a deformable operation claw 19 provided at the center of the front edge of the lid plate 17 and two engagement claws 20 provided at the rear edge of the lid plate 17 were provided on the main body 15. Engaging with the front engaging portion 21 and the two engaging holes 22, the lid plate 17 can be easily and firmly attached with one touch.
[0024]
As a result, when the storage box 11 rotates, even if a relatively heavy container is stored in the box, it is prevented from popping out and scattering. The cover plate 17 can be easily removed by disengaging the operating claw 19 and the front engaging portion 21 and then disengaging the engaging claw 20 and the engaging hole 22. At this time, since the notch 23 is provided in the front engaging portion 21, the operation claw 19 of the cover plate 17 can be deformed by hand and the engagement can be released.
[0025]
When the cover plate 17 is attached, the upper surface of the storage box 11 is flat. In particular, the back surface 24 (see FIG. 2) that can be seen when the storage box 11 is turned forward 180 ° and the storage box 11 is turned over is also formed flat. When an occupant sits on the seat cushion 12, the seating load is transmitted from the seat cushion 12 to the frame-like portion of the main body 15 and not transmitted to the lid plate 17. For this reason, the cover plate 17 can be made thin, and it contributes to the volume expansion of the storage box 11.
[0026]
As shown in FIG. 1, there is a gap behind the storage box 11, and the support bracket 25 stands on the step 7 in this gap, and the upper end of the support bracket 25 and the lower end and the rear end of the seat cushion 12 are hinges 26. Connected by
[0027]
Next, the operation of this embodiment will be described.
[0028]
In the present embodiment, the rear compartment 2 can be shifted from the passenger compartment state of FIG. 1 to the luggage compartment state of FIG. At this time, first, as shown by an arrow A ₁ in FIG. 1, the seat cushion 12 is rotated rearward to stand along the back panel 6. At this time, the seat cushion 12 approaches just below the seat back 13. Next, the storage box 11, as shown by arrow A ₂ in FIG. 1, moving on to the foot floor 9 to turn forward. In this case, a flat floor surface is formed by the back surface 24 and the step 7 of the storage box 11. At this time, the storage box 11 is turned upside down by 180 °. However, since the open portion of the upper surface of the main body 15 is firmly closed by the cover plate 17, the internal storage items are prevented from popping out and scattering.
[0029]
As described above, when the rear compartment 2 is used as a luggage compartment, a flat floor surface can be formed by the back surface 24 and the step 7 of the storage box 11, and the loadability can be improved. Further, the level difference 7 can be lowered by the height of the storage box 11, and the vehicle interior space can be expanded. That is, when the passenger compartment is formed, the storage box 11 and the step 7 can secure a sufficient height of the foot space, and when the passenger sits down, the foot is not cramped and is comfortable. On the other hand, when the luggage room is used, the height of the step 7 and the storage box 11 is higher than the foot floor 9 by the height H, and the height H is low. For example, a tall refrigerator or the like can be easily accommodated. Further, when used as a passenger compartment, the storage box 11 and the seat cushion 12 are stacked in two stages and supported in a mounted state. The support bracket 25 only supports the seat cushion 12 that stands up when used as a luggage compartment. Therefore, it is not necessary to make the support bracket 25 highly rigid, and the weight and cost can be suppressed by eliminating the need for a highly rigid bracket and seat cushion.
[0030]
Further, in the present embodiment, the center tunnel 10 is formed at a height H equal to the step 7, so that when it is used as a luggage compartment, the step 7, the storage box 11 and the center tunnel 10 can form a vast flat floor surface. The nature is further enhanced.
[0031]
The rear casing 2 has the same configuration on the left and right. For this reason, when it is set as a luggage compartment, the left and right steps 7 and the storage box 11 and the center tunnel 10 can realize a flat floor surface with a very large area, and large luggage can be loaded more stably.
[0032]
The foot floor 9 is usually dirty, and when the storage box 11 is turned forward, the upper surface of the storage box 11 comes into contact with the foot floor 9 and becomes dirty. However, when the storage box 11 is tilted backward and used as a seat, the seat cushion 12 is placed on the upper surface of the storage box 11, so that the passenger can sit without getting dirty.
[0033]
As described above, the embodiment of the present invention is not limited to the above. For example, the present invention is not limited to a pickup truck and can be applied to any vehicle. The configuration of the storage box is not limited to the above. For example, as shown in FIG. 3, a partition plate 27 that partitions the inside of the main body 15 forward and backward is added, thereby facilitating the arrangement of the storage box 11, increasing the rigidity of the storage box 11, and supporting the seating load. You may make it perform. The lid plate can be opened and closed freely.
[0034]
【The invention's effect】
The present invention exhibits the following excellent effects.
[0035]
(1) The loadability of luggage in the rear passenger compartment can be improved.
[0036]
(2) The interior space of the rear compartment can be expanded.
[0037]
(3) A high-rigidity bracket or the like is unnecessary, and the weight and cost can be suppressed.
