[0019] Next, an embodiment of the present invention will be described with reference to FIG. For the sake of convenience, in the following description, the front-rear direction, left-right direction, and up-down direction of the refuse collection vehicle 1 will be defined and described using the directions of arrows shown in FIGS.

[0020] [Overall configuration of garbage collection vehicle 1] First, the overall configuration of a refuse collection vehicle 1, which is an example of a specially equipped vehicle that embodies the present invention, will be described using Figure 1. A specially equipped vehicle is a vehicle that has mounted equipment suited to a variety of uses attached to the rear of a chassis 2, and specially equipped vehicles for various uses are manufactured by mounting mounted equipment suited to the use on a ready-made chassis 2.

[0021] The specially equipped vehicle in this embodiment is, for example, a refuse collection vehicle 1, which loads and collects refuse such as food waste and bulky waste. Note that the refuse collection vehicle 1 is an example of a specially equipped vehicle, and is not limited to a specific type of specially equipped vehicle, and may also be, for example, a dump truck, a concrete mixer truck, a tanker truck, a refrigerated truck, a high-altitude work vehicle, a fire engine, an ambulance, or the like. As shown in FIG. 1, the refuse collection vehicle 1 mainly comprises a chassis 2, a refuse collection box 3 which is an example of a mounted component, a refuse drop box 4, a loading device 6, a discharge plate 7, and the like.

[0022] The chassis 2 has a shape that extends in the front-rear direction, and a driver's cab 21 is provided at the upper front portion thereof. Furthermore, at the top of the chassis 2, behind the driver's cab 21, a garbage collection box 3 is provided.

[0023] The garbage collection box 3 is for collecting garbage that is put into the garbage collection truck 1. The trash collection box 3 is configured, for example, in a substantially rectangular parallelepiped shape extending in the front-rear direction, and the rear side is opened to form a substantially rectangular collection-side opening 3a.

[0024] Refuse thrown into the refuse collection vehicle 1 is loaded into the refuse collection box 3 through the storage side opening 3a and is stored in the refuse collection box 3.

[0025] In addition, a discharge plate 7, which will be described later, is provided inside the garbage storage box 3, and the garbage stored in the garbage storage box 3 can be discharged to the outside through the storage side opening 3a by the discharge plate 7. In addition, the garbage storage box 3 may be configured so that it can be rotatably connected to the chassis 2 in the vertical direction at the lower rear end without providing a discharge plate 7, and can be rotated upward and tilted by a dump cylinder (not shown) or the like, thereby allowing the garbage stored inside the garbage storage box 3 to be discharged to the outside through the storage side opening 3a. In other words, the garbage collection vehicle 1 in this embodiment is equipped with a discharge device consisting of a discharge plate 7 and a dump cylinder (not shown), which discharges garbage loaded into the garbage storage box 3 to the outside of the garbage storage box 3.

[0026] The garbage dump box 4 opens and closes the storage side opening 3a of the garbage storage box 3, and loads the garbage to be dumped into the garbage storage box 3. The trash drop box 4 is connected to the upper rear end of the trash collection box 3 so as to be rotatable in the vertical direction. Further, on the rear side of the trash bin 4, there are provided an inlet 4a through which trash is put in, and a cover member 4b for opening and closing the inlet 4a. Furthermore, an opening on the input side is provided on the front side of the garbage dump box 4, and the inside of the garbage dump box 4 is configured to be able to communicate with the inside of the garbage storage box 3 through this opening on the input side.

[0027] Next, the chassis 2, in particular the base structure of the chassis 2 on which the refuse collection box 3, which is an attached object, is mounted, will be described with reference to FIGS. 2 and 3. FIG.

[0028] 2 and 3, the base structure of the chassis 2 includes chassis frames 11 having a rectangular frame structure. Each chassis frame 11 is made of, for example, a steel material having a U-shaped cross section. Note that the chassis frame 11 may also be made of a steel material having a generally rectangular cylindrical cross section or an H-shaped steel material.

[0029] A cab 21 is located at the front end of the chassis frame 11, which forms the left and right sides of the rectangular frame structure, and in the rear area of ​​the cab 21, reinforcing members 13 are provided on the upper part of each chassis frame 11 to reinforce the chassis frame 11.

[0030] The reinforcing member 13 is provided in a direction perpendicular to the chassis frame 11 in a plan view, and a root portion 13a is provided at the connection point between the reinforcing member 13 and the upper surface of the chassis frame 11. The root portion 13a is configured in a substantially triangular shape in a plan view, and the upper surface of the root portion abuts against the underside of the upper surface of the chassis frame 11.

[0031] A root portion 13a of the reinforcing member 13 is fixed to the underside of the upper surface of the chassis frame 11 by a fastening member 14. The fastening member 14 is a component that is driven downward from the upper surface of the chassis frame 11 to fix it, and is formed by, for example, a rivet. Note that the fastening member 14 is not limited to a rivet, and may be, for example, a screw or a caulking component.

[0032] The subframe 12 is a frame for supporting the underside of the trash collection box 3, which is an attached object, and is made of, for example, a steel material having an H-shaped cross section. The subframe 12 is fixed to the underside of the trash collection box 3 by a mounting member (not shown), and by fixing the underside of the subframe 12 to the chassis frame 11 and supporting it, the trash collection box 3 is fixed to the chassis frame 11.

[0033] As shown in FIG. 3 , the floor plate 15 is provided between the subframe 12 for mounting a mounted object and the chassis frame. The floor plate 15 is a metal plate. The floor plate 15 has a clearance portion 15a through which the fastening member 14 protruding upward from the upper surface of the chassis frame 11 is inserted. The clearance portion 15a is configured as an insertion portion through which a portion of the fastening member 14 is inserted. The insertion portion is, for example, a hole. In this embodiment, as shown in FIG. 4 , a circular hole or an oval hole having a circular shape in a plan view is provided. Note that in this embodiment, the clearance portion 15a is formed as a hole, but is not limited thereto as long as it can avoid the upper end of the fastening member 14. For example, the clearance portion 15a can be formed as a recess or a notch. Note that when the clearance portion 15a is formed as a recess, inserting a portion of the fastening member 14 means that the fastening member 14 does not penetrate through the clearance portion, but rather that a portion of the fastening member 14 is stored in the recess.

[0034] 4, a plurality of floor plates 15 are provided, each having a connecting portion 15b that connects the plurality of floor plates 15 together. The connecting portion 15b is composed of an engaging claw and an engaged portion that meshes with the engaging claw, and the plurality of floor plates 15 can be connected together by engaging the engaging claw with the non-engaging portion.

[0035] The arrangement pattern of the avoidance portions 15a can be changed by changing the combination of the floor plates 15. For example, the arrangement pattern of the avoidance portions 15a may be formed in a pattern in which only oval holes are arranged in succession, a pattern in which only circular holes are arranged in succession, a pattern in which oval holes and circular holes are arranged in combination, a pattern in which recesses are arranged in succession without holes, or a pattern in which holes and recesses are arranged in combination. Furthermore, any of a plurality of patterns may be appropriately combined. For example, when multiple fastening members 14 are provided in the center of the chassis longitudinal direction to match the shape of the mounted object, the floor plates 15 are combined so that the oval holes are arranged in the center, as shown in FIG. 4. This eliminates the need to provide new avoidance portions 15a in the floor plates 15 during the process of attaching the mounted object and the subframe 12 to the chassis frame 11.

[0036] When attaching the mounted object to the chassis 2, floor plates 15 are placed on the upper surface of the chassis frame 11. The combination of floor plates 15 can be changed to match the arrangement pattern of the fastening members 14. After the floor plates 15 are placed, the subframe 12 is attached to the upper surface of the floor plates 15. Because the upper ends of the fastening members 14 are positioned within the avoidance portions 15a, the lower surface of the subframe 12 does not come into contact with the upper ends of the fastening members 14, and the entire floor plate 15 can support the subframe 12. In addition, a pair of floor plates 15 are provided symmetrically in the chassis width direction. This makes it possible to suppress tilting of the subframe 12 and the mounted object in the chassis width direction.

[0037] The specially equipped garbage collection vehicle 1 in this embodiment comprises a chassis 2, a garbage collection box 3 which is an example of an attached object mounted on the chassis 2, and a floor plate 15 interposed between the chassis 2 and the garbage collection box 3. The chassis 2 has a chassis frame 11 having a rectangular frame structure, a reinforcing member 13 which reinforces the chassis frame 11, and a fastening member 14 which fixes the reinforcing member 13 to the chassis frame 11, and the floor plate 15 has an avoidance portion 15a which avoids interference with the fastening member 14. By configuring it in this manner, the upper end of the fastening member 14 is positioned within the avoidance portion 15a, so that the lower surface of the subframe 12 and the upper end of the fastening member 14 do not come into contact with each other, and the entire floor plate 15 can support the subframe 12.

[0038] A plurality of floor plates 15 are provided, and each has connecting portions 15b that connect the plurality of floor plates 15 together. By configuring it in this way, the arrangement of the floor plate 15 can be adjusted to match the arrangement pattern of the fastening members 14. The combination can be changed.

[0039] In this embodiment, the floor plate 15 is made of metal, but is not limited to this and may be made of, for example, a resin material or an elastic material such as hard rubber. The upper and lower surfaces of the floor plate 15 can be reversed. The floor plate 15 can also be rotated 180° in the front-to-rear direction. This allows different arrangement patterns of the avoidance portions 15a to be prepared by reversing or rotating one floor plate 15.

[0040] The connecting portions 15b between the floor plates 15 are formed by an engaging claw and an engaged portion, but this is not limited to this and can be formed by joining with welding or adhesive, for example. Also, the connecting portions 15b may be formed by providing projections and depressions on both ends of the floor plates 15 and connecting them by fitting them together.

[0041] Furthermore, the reinforcing member 13 is provided in a direction perpendicular to the chassis frame 11 in a plan view, but is not limited to this and may be formed of, for example, a cross member. Also, a double reinforcing member may be provided inside the chassis frame 11 to further reinforce the reinforcing members together. [Explanation of symbols]
