Hereinafter, preferred embodiments of the present disclosure will be described in detail with reference to the drawings. Here, a flat body type loading platform mounted on a truck 100 is illustrated as the loading platform 1 of a freight vehicle. Further, in the following figures, the X direction is the longitudinal direction of the vehicle, the Y direction is the vehicle width direction, and the Z direction is the vertical direction.

First, an overview of the structure of the truck 100 will be explained with reference to FIG. The truck 100 shown in FIG. 1 includes a chassis 3, front wheels 5, rear wheels 7, a cab 8, and a loading platform 1. The chassis 3 is a structure that supports the members and devices that make up the truck 100, and can be exemplified by a structure in which an internal combustion engine, a drive mechanism, a steering mechanism, etc. are attached to a ladder frame or the like. The front wheels 5 and the rear wheels 7 are circular parts that move the truck 100 by frictional force with the road surface generated by rotation.In a typical truck 100, the front wheels 5 are attached to the steering mechanism of the chassis 3 and serve as steering wheels. , the rear wheels 7 are attached to a drive mechanism and serve as drive wheels.

The cab 8 is a driver's cabin of the truck 100, and includes a seat 11 on which a driver or a passenger is seated. FIG. 1 illustrates a structure in which only two seats 11 are provided: a driver's seat in the cab 8 and a passenger's seat provided next to the driver's seat in the vehicle width direction as necessary. Therefore, the seat 11 is the rearmost seat in the cab 8, and there is no rear seat behind the seat 11, but the back surface 9 of the cab 8 is provided.

The loading platform 1 is a box-shaped platform on which cargo is loaded, and here, a flat-body loading platform 1 is illustrated. The flat body type refers to a structure with a flat floor and surrounded by a wall-like fence, also called an aori.

In the truck 100 shown in FIG. 1, an upper back surface 9a, which is a portion of the back surface 9 of the cab 8, which is above the loading platform 1, is provided behind a lower back surface 9b, which is a portion below the loading platform 1. Thereby, a space called an expansion space 13 is formed between the seat 11 and the upper back surface 9a. The expansion space 13 is used for the purpose of increasing the tilting angle when the backrest of the seat 11 is tilted rearward around the lower end, so-called reclining, and for the purpose of securing luggage storage and sleeping space for the driver and fellow passengers. provided.

The cab 8 provided with the expansion space 13 in this manner is also called a space cab. In the space cab, the area below the expansion space 13 is the outside of the cab 8. In this way, in the space cab, the space outside the cab 8 behind the lower back surface 9b and below the expansion space 13 will be referred to as the lower space 15 in the following description. The above is an overview of the structure of the truck 100.

Next, details of the structure of the loading platform 1 of the truck 100 will be explained with reference to FIGS. 1 to 4. As shown in FIG. 2, the loading platform 1 includes a loading platform main body 21, a box portion 23, and a torii gate 25. The cargo platform 1 also includes a support structure 31 .

The loading platform body 21 is the rear end portion of the loading platform 1, and its outer shape is similar to that of a flat-body loading platform, with a floor plate 21a surrounded by a right side wall 21b, a left side wall 21c, and a rear wall 21d, which are wall-like fences. It has an enclosed structure.

The floor plate 21a is a rectangular member in a plan view that serves as a mounting surface for cargo loaded on the truck 100, and extends in the front-rear direction and the vehicle width direction. The width of the floor plate 21a in the vehicle width direction is approximately the same as that of the cab 8, and the width in the longitudinal direction is approximately the length obtained by subtracting the length of the cab 8 in the longitudinal direction from the overall length of the vehicle. In addition, the length of the cab 8 in the longitudinal direction here is the length between the front end of the cab 8 and the upper back surface 9a shown in FIG. 1. The thickness of the floor plate 21a in the Z direction is such that it will not be deformed by the load of the loaded cargo.

The right side wall part 21b and the left side wall part 21c shown in FIG. 2 are rectangular fences when viewed from the side, respectively, erected from the right end and the left end of the floorboard 21a. Since the right and left ends of the floor plate 21a are along the longitudinal direction of the vehicle, the longitudinal direction of the rectangles of the right side wall 21b and the left wall 21c are also along the longitudinal direction of the vehicle, and the length in the longitudinal direction is the same as that of the floor plate 21a. The length is approximately the same as the length in the front-back direction. The length in the Z direction, which is the vertical direction, is determined depending on the height of the cargo to be loaded, but generally the height of the upper end is less than the height of the upper end of the cab 8. The thickness in the Y direction, which is the vehicle width direction, is such that it will not deform even if it is pushed by cargo when it is loaded. The rear wall portion 21d is a rectangular fence when viewed from the rear and is erected from the rear end of the floorboard 21a. Since the rear end of the floor plate 21a is along the vehicle width direction, the longitudinal direction of the rear wall portion 21d is also along the vehicle width direction, and its length in the vehicle width direction is the same as the length of the floor plate 21a in the vehicle width direction. That's about it. The length of the rear wall portion 21d in the Z direction is approximately the same as the length of the right side wall portion 21b and the left side wall portion 21c in the Z direction. The thickness of the rear wall portion 21d in the front-rear direction is such that it will not deform even if it is pushed by the cargo when it is loaded. In this way, the loading platform main body 21 is surrounded by the floor plate 21a on the left, right, and rear sides, but the top and front surfaces are open.

The box portion 23 is a box-shaped portion constituting the front end of the loading platform 1, and has an upper surface covered with a top plate 23e, an open back surface, and is connected to the front surface of the loading platform main body 21. Furthermore, as shown in FIG. 1, at least a portion of the box portion 23 is disposed in a lower space 15 formed below the expansion space 13.

To explain the structure of the box part 23 more specifically, as shown in FIG. 2, the box part 23 includes a box part floor plate 23a, a header board 23d, a box part right side plate 23b, a box part left side plate 23c, and a top plate 23e. .

Like the floor plate 21a, the box floor plate 23a is a plate-shaped portion that is rectangular in plan view and serves as an installation surface for cargo to be loaded on the loading platform 1, and extends in the horizontal direction. The rear end of the box floor plate 23a is connected to the front end of the floor plate 21a. The length of the box floor plate 23a in the front-rear direction is slightly longer than the length of the lower space 15 in the front-rear direction. The length of the box floor plate 23a in the vehicle width direction is approximately the same as the length of the floor plate 21a in the vehicle width direction. The thickness of the box floor plate 23a in the Z direction is also approximately the same as the thickness of the floor plate 21a in the Z direction.

The header board 23d is a plate-like member that is rectangular in front view and constitutes the front surface of the box section 23, and is erected from the front end of the box section floor plate 23a. Since the front end of the box floor plate 23a is along the vehicle width direction, the longitudinal direction of the header board 23d is also along the vehicle width direction. The length of the header board 23d in the vehicle width direction is approximately the same as the length of the box floor plate 23a in the vehicle width direction. The height of the header board 23d in the Z direction is such that the upper end of the header board 23d does not come into contact with the lower surface of the expansion space 13 of the cab 8 that constitutes the upper surface of the lower space 15. The thickness of the header board 23d in the front-rear direction is such that it will not deform even if it is pushed by the cargo when it is loaded with cargo.

The box portion right side plate 23b and the box portion left side plate 23c are rectangular walls in side view that stand upright from the right end and the left end of the box portion floor plate 23a, respectively. The front ends of the box right side plate 23b and the box left side plate 23c are connected to the right and left ends of the header board 23d, respectively, and the rear ends are connected to the outer frame 27 of the torii gate 25, respectively. The length of the box portion right side plate 23b and the box portion left side plate 23c in the front-rear direction is approximately the same as the length of the box portion floor plate 23a in the front-rear direction. The thickness of the box portion right side plate 23b and the box portion left side plate 23c in the vehicle width direction is such that they will not deform even if they are pushed by the cargo when loaded. The heights of the box portion right side plate 23b and the box portion left side plate 23c in the Z direction are approximately the same as the height of the header board 23d in the Z direction.

The top plate 23e constitutes the upper surface of the box portion 23 and is a rectangular ceiling in plan view, and its longitudinal direction runs along the vehicle width direction. The length of the top plate 23e in the vehicle width direction is approximately the same as the length of the box floor plate 23a in the vehicle width direction, and the length of the top plate 23e in the longitudinal direction is approximately the same as the length of the box floor plate 23a in the longitudinal direction. The thickness of the top plate 23e in the Z direction is sufficient to support the torii gate 25. Furthermore, the portion of the box portion 23 disposed in the lower space 15 must have a height such that the upper surface of the top plate 23e does not come into contact with the lower surface of the expansion space 13 of the cab 8 that constitutes the upper surface of the lower space 15. There is.

The front end of the top plate 23e is connected to the upper end of the header board 23d. The right and left ends of the top plate 23e are connected to the upper ends of the box portion right side plate 23b and the box portion left side plate 23c. In this way, the box portion 23 has a box-like shape with the rear open.

The torii 25 is a gate-shaped structure that protects the cab 8 from the cargo loaded on the carrier body 21. Specifically, the torii 25 is a structure that covers the back surface 9 of the cab 8 from the outside in order to prevent the cargo loaded on the loading platform body 21 from coming into contact with the cab 8. erected above.

As shown in FIG. 2, the torii gate 25 includes an outer frame 27 and an inner support 29.

The outer frame 27 is a frame body serving as the outer peripheral portion of the torii gate 25, and has the shape of an upside-down U-shape when viewed from the front. Both ends of the U-shape are supported by the top plate 23e of the box portion 23. In FIG. 2, the box part right side plate 23b, the box part left side plate 23c, the box part floor plate 23a, and the floor plate 21a of the carrier main body 21 are also connected and supported.

The inner support 29 is a pillar that blocks the inside of the outer frame 27 and reinforces the outer frame 27 to prevent the cargo loaded on the carrier body 21 from coming into contact with the back surface 9 of the cab 8 from the inside of the outer frame 27. The inner support 29 is erected upward from the rear end of the top plate 23e, and its upper end is connected to the lower surface of the outer frame 27. A plurality of inner support columns 29 are provided inside the outer frame 27 at predetermined intervals in the vehicle width direction. The number of inner struts 29 is determined by the distance between adjacent inner struts 29 in the vehicle width direction, and the distance between the rightmost and leftmost inner struts 29 and the outer frame 27 in the vehicle width direction. The number is preferably shorter than the maximum horizontal width of . This is to prevent cargo from coming into contact with the back surface 9 of the cab 8 from between the adjacent inner support columns 29. Moreover, it is preferable that the number is necessary to reinforce the outer frame 27.

In this way, the loading platform 1 extends the loading platform 1 by providing the box section 23 in the lower space 15, which is a space below the expanded space 13 of the cab 8, so that even if the expanded space 13 is provided in the cab 8, the truck 100 is To prevent the cargo space on the flat surface of a loading platform 1 from decreasing as much as possible without increasing the overall length. Furthermore, by supporting the torii gate 25 on the top plate 23e of the box portion 23, a surface for supporting the torii gate 25 is secured.

Therefore, even when the front end of the loading platform 1 is provided in the lower space 15 which is the space below the expansion space 13 behind the seat 11 of the cab 8, the torii 25 can be provided in the loading platform 1. Further, by providing the top plate 23e on the top surface of the box portion 23, there is an advantage that rainwater is difficult to enter into the inside of the box portion 23 even though the loading platform 1 is of a flat body type.

The support structure 31 is a member that vertically connects the top plate 23e of the box portion 23 and the inner support 29 of the torii gate 25 to support the inner support 29, and is provided as necessary. As shown in FIGS. 3 and 4, the support structure 31 includes an upper member 35 and a lower member 37. As shown in FIGS.

The upper member 35 is a member that connects the top plate 23e of the box portion 23 and the inner support 29 of the torii gate 25, and FIG. 3 shows an example of an angle member that is L-shaped when viewed from the vehicle width direction and extends in the vehicle width direction. are doing. The angle material here means a member having an outer shape obtained by bending a long plate into an L-shape with a line along the longitudinal direction being a crease.

As shown in FIGS. 3 and 4, in the upper member 35, the upper member horizontal portion 51, which is one straight portion forming the L-shape, faces in the horizontal direction. Further, the front end 51a of the upper member horizontal portion 51, which is one straight portion, faces the header board 23d at the front end of the box portion 23. The upper surface of the upper member horizontal portion 51 is connected to the lower end of the inner support 29 of the torii gate 25 by a known connecting means such as welding. In the upper member 35, an upper member vertical part 55, which is the other straight part forming the L-shape, faces in the vertical direction and projects downward from the rear end of the upper member horizontal part 51. Further, as shown in FIG. 4, an upper member through hole 57 passes through the lower end of the upper member vertical portion 55 in the front-rear direction. On the other hand, the top plate 23e of the box portion 23 has a plate-shaped top plate-side connecting portion 33 that projects upward from the rear end and has a surface facing the vehicle width direction and the vertical direction.

In this configuration, the bolt 41 with a head is inserted into the upper member through hole 57 and the through hole (not shown) of the top plate side connection part 33, and the nut 43 is screwed onto the bolt 41, and the bolt head and nut 43 are connected to the upper member vertical part. 55 and the top plate side connection part 33 are sandwiched. Thereby, the lower end of the upper member 35 is connected to the box part 23, and the upper member 35 connects the top plate 23e of the box part 23 and the inner support 29 of the torii gate 25.

The lower member 37 is arranged inside the upper member 35 which is bent into an L-shape, and the upper member horizontal part 51 which is one straight part of the upper member 35 and the upper member vertical part 55 which is the other straight part are connected to each other. This is a member that absorbs the load of the torii gate 25 by connecting and reinforcing it. The inside of the L-shaped bend means the side with the smaller angle of the two angles of the L-shaped bend when viewed from the side. For example, in FIG. 4, the angles of the L-shaped bent portions are 90° and 270°, and the inside means the side where the angle is 90°.

Specifically, the lower member 37 includes a reinforcing portion 61 and a lower member connecting portion 63. The reinforcing part 61 is a member that connects and reinforces the inner sides of the L-shape of the upper member vertical part 55, and as shown in FIG. It has an outer shape that extends in the vehicle width direction. Digital numerals here mean Arabic numerals displayed on a 7-segment display. A 7-segment display is also called a Japanese character display.

Specifically, the uppermost surface horizontal portion 61a of the reinforcing portion 61 faces in the horizontal direction and extends in the vehicle width direction. 51 is supported. The lower first vertical portion 61b that protrudes vertically downward from the rear end of the uppermost surface horizontal portion 61a is in contact with the front surface of the upper member vertical portion 55 of the upper member 35, and is a spot welded joint. They are joined at a portion 67. As a result, the uppermost surface horizontal portion 61a and the lower first vertical portion 61b connect and support the inner sides of the upper member horizontal portion 51 and the upper member vertical portion 55 of the upper member 35.

Further, the reinforcing part 61 includes a lower first horizontal part 61c that projects horizontally forward from the lower end of the lower first vertical part 61b, and a lower part that projects from the front end of the lower first horizontal part 61c to the lower end in the vertical direction. A side second vertical portion 61d is provided. The reinforcing portion 61 also includes a lower second horizontal portion 61e that projects horizontally backward from the lower end of the lower second vertical portion 61d. Note that the first lower vertical portion 61b, the first lower horizontal portion 61c, the second lower vertical portion 61d, and the second lower horizontal portion 61e also extend in the vehicle width direction.

The lower member connecting portion 63 is a member that connects the lower member 37 with the upper member 35 and the top plate side connecting portion 33, and is the right side of the reinforcing portion 61 in the shape of a “2” or an S-shape inverted horizontally. This is a member that projects downward from the lower end, that is, the rear end of the lower second horizontal portion 61e, and extends in the vehicle width direction. A lower member through hole 65 is formed in the lower member connecting portion 63 so as to extend through the lower member connecting portion 63 in the front-rear direction.

Further, by screwing and fastening the nut 43 onto the tip of the bolt 41, the lower member connecting portion 63 is fixed to the upper member 35 and the top plate 23e. Therefore, the lower end of the lower member connecting portion 63 is fixed to the top plate 23e and the upper member vertical portion 55, and the reinforcing portion 61 and the lower member connecting portion 63 connect the inner sides of the upper member horizontal portion 51 and the upper member vertical portion 55. and support.

In this way, the loading platform 1 may have a configuration in which the top plate 23e of the box portion 23 supports the inner support 29 of the torii gate 25 via the support structure 31. With this configuration, even when the inner support 29 of the torii gate 25 is provided on the upper surface of a plate that is not supported downwardly, such as the top plate 23e, the inner support support 29 of the torii gate 25 can be supported without buckling of the top plate 23e.

Further, in this configuration, the upper member 35 of the support structure 31 connects the top plate 23e and the inner support 29 of the torii gate 25, and the lower member 37 reinforces the upper member 35 from the inside to prevent buckling. Therefore, compared to the case where the top plate 23e and the inner support column 29 of the torii gate 25 are directly connected, or the case where the top plate 23e and the inner support column 29 of the torii gate 25 are connected only by the upper member 35, the top plate 23e and the inner support column 29 of the torii gate 25 are connected. The strength of the connection portion between the inner support column 29 and the inner support column 25 can be improved.

Furthermore, in this configuration, the reinforcing portion 61 of the lower member 37 has an outer shape in which the flat plate is bent into the shape of the digital number "2" or the shape of the left-right reversed S-shape when viewed from the side, and the shape of the torii 25 is Buckling is prevented by the reinforcing portion 61 receiving the load of the inner support 29.

With this configuration, compared to a case where the lower member 37 is a flat plate like the header board 23d, the lower member 37 can be made lighter and have the same strength. Therefore, even when the inner column 29 of the torii gate 25 is supported by a member, such as the top plate 23e, that is not directly supported by the floor plate 21a of the loading platform 1 or the box part floor plate 23a of the box part 23, the weight of the support structure 31 This can prevent the top plate 23e from buckling.
