Disclosure of Invention
Problems to be solved by the invention
In the flathead truck disclosed in patent document 1, a rear portion of the floor underframe extends substantially horizontally, and is fixed to the cab in a state of being in contact with a lower surface of the floor panel. That is, since the floor panel fixed to the rear portion of the floor bottom frame linearly extends in the front-rear direction, it is difficult to ensure the rigidity of the floor panel with respect to a load input from the vehicle width direction (hereinafter, referred to as a load from the vehicle width direction) in the rear region of the cab. In particular, in a vehicle such as a long-distance truck or the like having a resting space for an occupant behind a seat, the length of a floor panel in the front-rear direction in a region behind the seat of a cab (hereinafter simply referred to as a rear region of the cab) is longer than the length of the floor panel in the front-rear direction, and therefore there is a risk that: the rigidity of the floor panel in the rear region of the cab against a load from the vehicle width direction cannot be sufficiently ensured.
Accordingly, the present disclosure provides a floor panel structure of a cab capable of securing rigidity of a floor panel in a rear region of the cab against a load from a vehicle width direction.
Means for solving the problems
A first embodiment of the present disclosure is a floor panel structure of a cab, which extends continuously forward from a lower end edge portion of a cab rear surface portion that defines a rear of a vehicle compartment of the cab, forms a floor surface of the vehicle compartment, and supports a seat for sitting in the vehicle compartment from below, and which includes a seat support portion, a seat rear tubular portion, and a panel rear end edge portion. The seat support portion fixes the seat to support the seat from below. The seat rear tubular portion is disposed rearward of the seat support portion and extends in the vehicle width direction across the entire width of the cab. The seat rear tubular portion has a closed cross-sectional shape. The panel rear end edge portion extends in the vehicle width direction across the entire width of the cab at a rear end lower portion of the cab rearward of the seat rear tubular portion, and is fixed to a lower end edge portion of a cab rear surface portion.
In the above configuration, a closed cross-sectional seat rear tubular portion extending in the vehicle width direction across the entire width of the cab is provided between the seat support portion and the panel rear end edge portion. Therefore, the rigidity of the region of the floor panel between the seat support portion and the panel rear end edge portion with respect to a load from the vehicle width direction can be ensured by the seat rear cylindrical portion.
Further, since the seat is fixed to the seat support portion, the rigidity with respect to the load from the vehicle width direction can be ensured by the seat in the region of the floor panel having the seat support portion. Further, since the panel rear end edge portion of the floor panel extends in the vehicle width direction across the entire width of the cab and is fixed to the lower end edge portion of the cab rear surface portion, the rigidity of the panel rear end edge portion of the floor panel with respect to a load from the vehicle width direction can be secured by the cab rear surface portion.
Therefore, the rigidity of the floor panel in the region (rear region) rearward of the seating seat of the cab with respect to the load in the vehicle width direction can be ensured.
A 2 nd embodiment of the present disclosure is the floor panel structure of the 1 st embodiment, and includes a seat rear floor portion disposed between the seat rear cylindrical portion and the panel rear end edge portion. The seat rear tubular portion includes: a 1 st upper plate portion which is disposed above the seat rear floor portion and which defines an upper portion of an internal space of the seat rear tubular portion; and a 1 st vertical plate portion extending downward from a rear end edge of the 1 st upper plate portion and defining a rear portion of the internal space. The seat rear floor section extends continuously rearward from the 1 st vertical plate section of the seat rear tubular section. The panel rear end edge part has: a 2 nd vertical plate portion standing along a rear end edge of the seat rear floor portion; and a 2 nd upper plate portion extending rearward from an upper end edge of the 2 nd vertical plate portion. A concave space opened upward is formed between the 1 st vertical plate portion of the seat rear tubular portion, the seat rear floor portion, and the 2 nd vertical plate portion of the panel rear end edge portion.
In the above configuration, the panel rear end edge portion includes: a 2 nd vertical plate portion standing along a rear end edge of the seat rear floor portion; and a 2 nd upper plate portion extending rearward from an upper end edge of the 2 nd vertical plate portion. That is, at least 2 corner portions, that is, a corner portion where the seat rear floor portion and the 2 nd vertical plate portion intersect each other and a corner portion where the 2 nd vertical plate portion and the 2 nd upper plate portion intersect each other, are formed at the panel rear end edge portion. Therefore, the rigidity of the panel rear end edge portion of the floor panel against a load from the vehicle width direction can be ensured by at least 2 corner portions.
Further, since the recessed space opened upward is formed between the rear plate portion of the seat rear tubular portion, the seat rear floor portion, and the front plate portion of the panel rear end edge portion, the recessed space can be utilized as a housing space for small objects and the like, and the rear region of the cab can be effectively utilized.
Effects of the invention
According to the present disclosure, the rigidity of the floor panel in the rear region of the cab with respect to a load from the vehicle width direction can be ensured.

Although the rail upper plate portion 26b is slightly separated from the bed 13 in fig. 4 for easy understanding, the bed 13 is actually placed on the rail upper plate portion 26b, and the rail upper plate portion 26b is in contact with the bed 13.
The 3 rd panel member 18 of the floor panel 10 has an upper fixing plate portion 18a engaged in a state of surface contact with the lower surface of the bed supporting floor portion 21 of the 1 st panel member 16, a lower fixing plate portion 18b engaged in a state of surface contact with the upper surface of the cab rear floor portion 25 of the 2 nd panel member 17, and a middle plate portion (1 st vertical plate portion) 18c extending between the upper fixing plate portion 18a and the lower fixing plate portion 18b, and the 3 rd panel member 18 extends in the vehicle width direction across the entire width of the cab 2. The rear end edge of the upper fixing plate portion 18a is disposed at the rear end edge portion of the bed supporting floor portion 21 of the 1 st panel member 16. The front end edge of the lower fixing plate portion 18b is disposed at a position separated rearward from the rear surface 27 of the inclined floor portion 20 of the 1 st panel member 16. The middle plate portion 18c extends between the rear end edge of the upper fixing plate portion 18a and the front end edge of the lower fixing plate portion 18 b.
The upper region 20b of the inclined floor portion 20 of the 1 st panel member 16, the bed supporting floor portion 21 of the 1 st panel member 16, the middle plate portion 18c of the 3 rd panel member 18, and the front end region 33 of the cab rear floor portion 25 of the 2 nd panel member 17 forward of the middle plate portion 18c of the 3 rd panel member 18 form a tubular portion (seat rear tubular portion) 34 extending in the vehicle width direction across the entire width of the cab 2. The tubular portion 34 is disposed rearward of the rear seat fixing portion 22a of the floor panel 10 and forward of a panel rear end edge portion (in the present embodiment, the rear cab attachment rail 26) of the floor panel 10. The cross section of the cylindrical portion 34 perpendicular to the vehicle width direction is a substantially rectangular closed cross section. That is, the inner space 35 of the tubular portion 34 is defined in the front by the upper region 20b of the inclined floor portion 20 of the 1 st panel member 16, in the upper portion by the bed supporting floor portion 21 of the 1 st panel member 16, in the rear portion by the middle plate portion 18c of the 3 rd panel member 18, and in the lower portion by the front end region 33 of the cab rear floor portion 25 of the 2 nd panel member 17. The tubular portion 34 protrudes upward from the cab front floor portion 19 of the 1 st panel member 16 forward of the tubular portion 34 and the cab rear floor portion 25 of the 2 nd panel member 17 rearward of the tubular portion 34.
The intermediate plate portion 18c of the 3 rd panel member 18, the seat rear floor portion 36 of the cab rear floor portion 25 of the 2 nd panel member 17, which is located rearward of the intermediate plate portion 18c of the 3 rd panel member 18, and the rail vertical plate portion 26a of the rear cab attachment rail 26 define a concave space 37 that opens upward. The seat rear floor portion 36 extends continuously rearward from the lower end of the middle plate portion 18c of the 3 rd panel member 18. That is, the seat rear floor portion 36 is disposed between the tubular portion 34 and the rear cab attachment rail 26, and connects the tubular portion 34 and the rear cab attachment rail 26. In a state where the bed 13 is placed on the bed support floor portion 21 of the 1 st panel member 16 and the rail upper plate portion 26b of the rear cab attachment rail 26, the upper portion of the concave space 37 is closed by the bed 13. In addition, the upper part of the concave space 37 is opened in a state where at least one of the front end edge part 13a and the rear end edge part 13b of the bed 13 is moved upward.
In the floor panel 10 configured as described above, a tubular portion 34 having a closed cross-sectional shape extending in the vehicle width direction across the entire width of the cab 2 is formed between the seat fixing portion 22 to which the seat 11 is fixed and the rear cab attachment rail 26. Therefore, the tubular portion 34 can ensure the rigidity of the region of the floor panel 10 between the seat fixing portion 22 and the rear cab attachment rail 26 against a load from the vehicle width direction. That is, the rigidity of the floor panel 10 in the rear region 14 of the cab 2 against a load from the vehicle width direction can be ensured.
Further, since the seat 11 is fixed to the seat fixing portion 22 of the 1 st panel member 16, the seat 11 can ensure rigidity against a load from the vehicle width direction in the region of the floor panel 10 having the seat fixing portion 22 (the rear region 39b of the 1 st panel member 16).
Further, since the rear panel 28 is fixed to the panel rear end edge portion of the floor panel 10 (the rear cab attachment rail 26 in the present embodiment), the rear panel 28 can ensure rigidity of the panel rear end edge portion of the floor panel 10 against a load from the vehicle width direction.
Rear cab attachment rail 26 includes a vertical rail plate portion 26a that is bent from a rear end edge of cab rear floor portion 25 and extends upward, a vertical rail plate portion 26b that is bent from an upper end edge of vertical rail plate portion 26a and extends rearward, and a rear rail plate portion 26c that is bent from a rear end edge of upper rail plate portion 26b and extends downward, and rear cab attachment rail 26 extends in the vehicle width direction across the entire width of cab 2 at a rear end lower portion of cab 2. That is, 3 corner portions 40, 41, and 42, that is, a corner portion 40 where the cab rear floor portion 25 and the rail vertical plate portion 26a intersect, a corner portion 41 where the rail vertical plate portion 26a and the rail upper plate portion 26b intersect, and a corner portion 42 where the rail upper plate portion 26b and the rail rear plate portion 26c intersect, are formed on the rear cab attachment rail 26, and these 3 corner portions extend in the vehicle width direction across the entire width of the cab 2. Therefore, the 3 corner portions 40, 41, and 42 can ensure the rigidity of the rear end edge portion of the floor panel 10 against a load from the vehicle width direction.
Therefore, the rigidity of the floor panel 10 in the rear region 14 rearward of the seat 11 of the cab 2 with respect to a load from the vehicle width direction can be ensured.
Further, since the middle plate portion 18c of the 3 rd panel member 18, the seat rear floor portion 36 of the 2 nd panel member 17, and the rail vertical plate portion 26a of the rear cab attachment rail 26 define a concave space 37 that opens upward, the concave space 37 can be used as a storage space for small objects and the like. In this way, since the rear region 14 of the cab 2 can be used as the resting space 12 for the occupant having the bed 13, and the concave space 37 below the bed 13 can be used as the accommodation space for small articles and the like, the rear region 14 of the cab 2 can be effectively utilized. Further, since the concave space 37 is provided below the bed 13, the dead space (dead space) below the bed 13 can be prevented from being formed.
In the present embodiment, the floor panel 10 is configured by joining 3 panel members 16, 17, and 18, i.e., the 1 st panel member 16, the 2 nd panel member 17, and the 3 rd panel member 18, but the number of panel members configuring the floor panel 10 is not limited to this. The joint between the 3 panel members 16, 17, and 18 is not limited to the above joint.
In addition, although in the present embodiment, the floor base frame 15 is provided, the floor base frame 15 includes: a front portion 15 a; an inclined portion 15b extending obliquely rearward and upward continuously from a rear end of the front portion 15 a; and a rear portion 15c extending substantially horizontally from a rear end of the inclined portion 15b to a rear end portion of the cab 2, but the shape of the floor underframe 15 is not limited thereto.
Although the cab rear surface portion 5 (the lower end edge portion 28a of the rear plate 28) is fixed to the rail rear plate portion 26c of the rear cab attachment rail 26 in the present embodiment, the cab rear surface portion 5 may be fixed to the rail vertical plate portion 26a, the rail upper plate portion 26b, or the like of the rear cab attachment rail 26.
In the present embodiment, the bed 13 is provided in the rest space 12 of the rear region 14 of the cab 2, but the present invention is not limited to this, and any plate-shaped member may be used as long as it functions as a lid that closes the upper part of the concave space 37 so as to be openable and closable. Alternatively, the recessed space 37 of the rear region 14 of the cab 2 may be opened upward without providing the bed 13.
In the present embodiment, the rear cab attachment rail 26 supported from below by the vehicle body frame (not shown) is provided at the panel rear end edge portion of the floor panel 10, but the present invention is not limited to this. For example, instead of providing the rear cab attachment rail 26 at the panel rear end edge portion of the floor panel 10, the panel rear end edge portion of the floor panel 10 may be fixed to the lower end edge portion 28a of the rear panel 28 of the cab rear portion 5. Even in this case, since the rear panel 28 is fixed to the panel rear end edge portion of the floor panel 10, the rear panel 28 can ensure rigidity of the panel rear end edge portion of the floor panel 10 against a load from the vehicle width direction.
In the present embodiment, the cab rear floor portion 25 of the 2 nd panel member 17 extends substantially horizontally and is disposed at substantially the same height position as the seat rear floor portion 36 of the 2 nd panel member 17 below the recessed space 37 defining the rear region 14 of the cab 2 and the front end edge portion 33 of the 2 nd panel member 17 below the internal space 35 defining the tubular portion 34, but the present invention is not limited thereto.
For example, as shown in fig. 5 (a), the seat rear floor portion 47a of the panel member 47 below the concave space 37 may be arranged above the front end edge portion 47b of the panel member 47 below the internal space 45 defining the tubular portion (seat rear tubular portion) 44. In this case, the rear of the internal space 45 of the cylindrical portion 44 may be defined by the vertical plate portions (1 st vertical plate portion) 46a, 47c of the 2 panel members 46, 47, and the seat rear floor portion 47a of the panel member 47 may be continuously extended rearward from the upper end of the vertical plate portion 47c of the panel member 47.
As shown in fig. 5b, the seat rear floor portion 57a of the panel member 57 below the concave space 37 may be disposed below the front end edge portion 57b of the panel member 57 below the internal space 55 defining the tubular portion (seat rear tubular portion) 54. In this case, the seat rear floor portion 57a of the panel member 57 may have a vertical plate portion 58 that is bent from the rear end edge of the front end edge portion 57b and extends downward, and a horizontal plate portion 59 that is bent from the lower end edge of the vertical plate portion 58 and extends rearward, and the lower end edge portion of the vertical plate portion (1 st vertical plate portion) 56a of the panel member 56 that defines the rear of the internal space 55 of the tubular portion 54 may be joined to the upper end edge portion of the vertical plate portion of the seat rear floor portion 57 a.
