[0005] In the meantime, in a sealing structure for sealing the gap between the cabin section and the rear body section from rainwater and the like outside the automobile, a structure capable of sealing the gap between the cabin section and the rear body section with a simple structure is desired.

[0006] SUMMARY OF THE PRESENT EMBODIMENTS An object of the present invention is to provide a sealing structure between a cabin portion and a rear body portion that is capable of sealing the space between the cabin portion and the rear body portion with a simple structure. [Means for solving the problem]

[0007] The present invention provides a sealing structure for a cabin part and a rear body part, the sealing structure comprising: a cabin part having a cabin opening opened at its rear end; a rear body part having a rear body opening opened at its front end, the interior of the cabin part communicating with the interior of the cabin part via the cabin opening and the rear body opening; and a hood member connecting the cabin opening and the rear body opening while sealing the space between the cabin opening and the rear body opening, the hood member being fixed at the cabin opening between a cabin seal member arranged on the inner surface of the cabin opening and a cabin retainer member arranged at a position farther from the inner surface of the cabin opening than the cabin seal member, while sealing between the inner surface of the cabin opening and the hood member by the cabin seal member; and the sealing structure for a cabin part and a rear body part, the sealing structure comprising: a cabin part having a cabin opening opened at its rear end; a rear body opening opened at its front end;

[0008] According to this configuration, in a sealing structure between a cabin portion and a rear body portion, which includes a hood member that connects the cabin opening of the cabin portion and the rear body opening of the rear body portion while sealing the gap between the cabin opening and the rear body opening, the hood member is fixed at the cabin opening between a cabin seal member arranged on the inner surface of the cabin opening and a cabin retainer member arranged at a position farther from the inner surface of the cabin opening than the cabin seal member, while sealing between the inner surface of the cabin opening and the hood member by the cabin seal member, and at the rear body opening, the hood member is fixed between a rear body seal member arranged on the inner surface of the rear body opening and a rear body retainer member arranged at a position farther from the inner surface of the rear body opening than the rear body seal member, while sealing between the inner surface of the rear body opening and the hood member by the rear body seal member, thereby enabling sealing between the cabin portion and the rear body portion with a simple structure.

[0009] In this case, it is preferable that the hood member, the cabin seal member and the rear body seal member are integrated with one another as a seal portion.

[0010] According to this configuration, the hood member, the cabin seal member and the rear body seal member are integrated with one another as the seal portion, so that the seal portion can be easily assembled to the cabin opening and the rear body opening.

[Figure 6] 3 is an enlarged perspective view of a portion A in FIG. 2. DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0019] Hereinafter, a sealing structure between a cabin part and a rear body part according to an embodiment of the present invention will be described in detail with reference to the drawings. The sealing structure between a cabin part and a rear body part of this embodiment is applied to, for example, a freight vehicle. As shown in FIG. 1, the sealing structure between a cabin part and a rear body part of this embodiment includes a cabin part 2 having a driver's seat and a passenger seat, and a rear body part 3 having a luggage compartment. The cabin part 2 and the rear body part 3 are manufactured separately, and are mounted separately on the chassis of the automobile, and then connected to each other. The rear body part 3 has a front gate frame 4 at its front end. The cabin part 2 and the rear body part 3 are connected via the front gate frame 4.

[0020] As shown in Figure 2, the cabin section 2 has a cabin opening 6 that opens at its rear end. The cabin opening 6 has an upper portion 15, a side portion 17, and a lower portion 19. The rear body section 3 has a rear body opening 7 that opens at its front end. The rear body opening 7 has an upper portion 16, a side portion 18, and a lower portion 20. The interior of the rear body section 3 is in communication with the interior of the cabin section 2 via the cabin opening 6 and the rear body opening 7 (walk-through).

[0021] 1 and 2, the sealing structure 1 includes a hood member 5 that connects the cabin opening 6 and the rear body opening 7 while sealing the gap between the cabin opening 6 and the rear body opening 7. The hood member 5 is, for example, a waterproof cloth coated with a synthetic resin such as polyvinyl chloride. The hood member 5 is flexible and bendable.

[0022] 2, 3, 4 and 5, particularly 4, the cabin opening 6 and the rear body opening 7 face each other but are spaced apart from each other. An inner peripheral surface 8 of the cabin opening 6 and an inner peripheral surface 11 of the rear body opening 7 have corresponding shapes and extend parallel to each other in the fore-and-aft direction of the cabin portion 2 and the rear body portion 3.

[0023] At the cabin opening 6, the hood member 5 is fixed between the inner circumferential surface 8 of the cabin opening 6 and the hood member 5, with the cabin seal member 9 arranged on the inner circumferential surface 8 of the cabin opening 6 and the cabin retainer member 10 arranged at a position farther away from the inner circumferential surface 8 of the cabin opening 6 than the cabin seal member 9. At the rear body opening 7, the hood member 5 is fixed between the inner circumferential surface 11 of the rear body opening 7 and the hood member 5, with the rear body seal member 12 arranged on the inner circumferential surface 11 of the rear body opening 7 and the rear body retainer member 13 arranged at a position farther away from the inner circumferential surface 11 of the rear body opening 7 than the rear body seal member 12.

[0024] The hood member 5 is arranged in a slackened state, with the length in the front-to-rear direction of the cabin portion 2 and the rear body portion 3 being longer than the distance between the cabin opening 6 and the rear body opening 7. The hood member 5, cabin seal member 9, cabin retainer member 10, rear body seal member 12 and rear body retainer member 13 are arranged around the entire inner circumferential surface 8 of the cabin opening 6 and the inner circumferential surface 11 of the rear body opening 7.

[0025] The cabin seal member 9 and the rear body seal member 12 are, for example, rubber plates having a thickness of about several mm. The cabin retainer member 10 and the rear body retainer member 13 are, for example, metal plates having a thickness of about several mm. As shown in FIG. 3, the hood member 5, the cabin seal member 9, and the rear body seal member 12 are integrated with each other as a seal portion 14. More specifically, as shown in FIG. 2 and FIG. 3, the seal portion 14 is divided into an upper seal portion 21 arranged on upper portions 15, 16 and both side portions 17, 18 of the cabin opening 6 and the rear body opening 7, a lower seal portion 22 arranged on lower portions 19, 20 of the cabin opening 6 and the rear body opening 7, and a connecting seal portion 23 that bridges between the upper seal portion 21 and the lower seal portion 22.

[0026] The cabin retainer member 10 is divided into an upper cabin retainer member 24 arranged on the upper part 15 of the cabin opening 6, a lower cabin retainer member 25 arranged on the lower part 19 of the cabin opening, and a pair of side cabin retainer members 26 arranged on the sides 17 of the cabin opening 6 and spanning between the upper cabin retainer member 24 and the lower cabin retainer member 25.

[0027] In this embodiment, only the side cabin retainer member 26 is separate from the upper seal portion 21, the lower seal portion 22, and the joint seal portion 23. The upper cabin retainer member 24 is integrated with the upper portion of the upper seal portion 21. The lower cabin retainer member 25 is integrated with the lower portion of the upper seal portion 21, the lower seal portion 22, and the joint seal portion 23. A gap is provided between the upper cabin retainer member 24 at the upper portion of the upper seal portion 21 and the lower cabin retainer member 25 at the lower portion of the upper seal portion 21 for the side cabin retainer member 26 to be attached later.

[0028] The rear body retainer member 13 is divided into an upper rear body retainer member 27 arranged on the upper part 16 of the rear body opening 7, a lower rear body retainer member 28 arranged on the lower part 20 of the rear body opening 7, and a pair of lateral rear body retainer members 29 arranged on the sides 18 of the rear body opening 7 and spanning between the upper rear body retainer member 27 and the lower rear body retainer member 28.

[0029] In this embodiment, only the side rear body retainer members 29 are separate from the upper seal portion 21, the lower seal portion 22, and the joint seal portion 23. The upper rear body retainer member 27 is integrated with the upper portion of the upper seal portion 21. The lower rear body retainer member 28 is integrated with the lower portion of the upper seal portion 21, the lower seal portion 22, and the joint seal portion 23. A gap is provided between the upper rear body retainer member 27 at the upper portion of the upper seal portion 21 and the lower rear body retainer member 28 at the lower portion of the upper seal portion 21 for the side rear body retainer members 29 to be attached later.

[0030] The cabin seal member 9 of the upper seal portion 21 and the cabin seal member 9 of the joint seal portion 23 overlap with each other in their covering areas of the inner circumferential surface 8. The rear body seal member 12 of the upper seal portion 21 and the rear body seal member 12 of the joint seal portion 23 overlap with each other in their covering areas of the inner circumferential surface 11. The cabin seal member 9 of the lower seal portion 22 and the cabin seal member 9 of the joint seal portion 23 overlap with each other in their covering areas of the inner circumferential surface 8. The rear body seal member 12 of the lower seal portion 22 and the rear body seal member 12 of the joint seal portion 23 overlap with each other in their covering areas of the inner circumferential surface 11.

[0031] On the other hand, the areas where the lower cabin retainer member 25 at the lower part of the upper seal portion 21 and the lower cabin retainer member 25 of the joining seal portion 23 cover the inner circumferential surface 8 may overlap with each other, or may not overlap at all. The areas where the lower rear body retainer member 28 at the lower part of the upper seal portion 21 and the lower rear body retainer member 28 of the joining seal portion 23 cover the inner circumferential surface 11 may overlap with each other, or may not overlap at all.

[0032] The areas where the lower cabin retainer member 25 of the lower seal portion 22 and the lower cabin retainer member 25 of the joining seal portion 23 cover the inner circumferential surface 8 may overlap with each other, or may not overlap at all. The areas where the lower rear body retainer member 28 of the lower seal portion 22 and the lower rear body retainer member 28 of the joining seal portion 23 cover the inner circumferential surface 11 may overlap with each other, or may not overlap at all.

[0033] The areas where the upper cabin retainer member 24 at the upper part of the upper seal portion 21 and the lateral cabin retainer member 26 cover the inner circumferential surface 8 may overlap with each other, or may not overlap at all. The areas where the upper rear body retainer member 27 at the upper part of the upper seal portion 21 and the lateral rear body retainer member 29 cover the inner circumferential surface 11 may overlap with each other, or may not overlap at all.

[0034] The areas where the lower cabin retainer member 25 at the lower part of the upper seal portion 21 and the lateral cabin retainer member 26 cover the inner circumferential surface 8 may overlap with each other, or may not overlap at all. The areas where the lower rear body retainer member 28 at the lower part of the upper seal portion 21 and the lateral rear body retainer member 29 cover the inner circumferential surface 11 may overlap with each other, or may not overlap at all.

[0035] 5 and 6, the cabin section 2 has a roof 30 above. At the cabin opening 6, the hood member 5 is fixed by bolts 31 and nuts 32 inserted through bolt holes in the upper cabin retainer member 24, the hood member 5, the cabin seal member 9, and the upper cabin retainer member 24, while sealing the gap between the inner circumferential surface 8 of the cabin opening 6 and the hood member 5 by the cabin seal member 9 between the cabin opening 6 and the upper cabin retainer member 24, which is disposed at a position farther from the inner circumferential surface 8 of the cabin opening 6 than the cabin seal member 9.

[0036] At the rear body opening 7, the hood member 5 is fixed by a rear body seal member 12 arranged on the inner surface 11 of the rear body opening 7 and an upper rear body retainer member 27 arranged at a position farther from the inner surface 11 of the rear body opening 7 than the rear body seal member 12, with the space between the inner surface 11 of the rear body opening 7 and the hood member 5 being sealed by the rear body seal member 12, while the space between the inner surface 11 of the rear body opening 7 and the hood member 5 is sealed by the rear body seal member 12, the upper rear body retainer member 27, the hood member 5, the rear body seal member 12 and a bolt 31 and a nut 32 inserted through bolt holes in the upper rear body retainer member 27, the hood member 5, the rear body seal member 12 and the upper part 16 of the rear body portion 3.

[0037] When manufacturing a freight vehicle, the cabin section 2 is mounted on the chassis of the freight vehicle, and then the rear body section 3 is mounted on the chassis. At this time, the positions at which the cabin section 2 and the rear body section 3 are mounted on the chassis vary by about 10 mm in the front-rear direction and by several mm in the lateral and vertical directions. The shapes of the cabin opening 6 and the rear body opening 7 also vary by about several mm. After the cabin section 2 and the rear body section 3 are mounted on the chassis, the hood member 5, the cabin seal member 9, the cabin retainer member 10, the rear body seal member 12 and the rear body retainer member 13 are assembled to the cabin opening 6 and the rear body opening 7, and the cabin section 2 and the rear body section 3 are connected by the hood member 5.

[0038] The installation of the top member 5 and the like to the cabin opening 6 and the rear body opening 7 is performed, for example, as follows. The upper seal part 21, in which the upper cabin retainer member 24, the upper rear body retainer member 27, the lower cabin retainer member 25 and the lower rear body retainer member 28 are integrated, is attached to the upper part 15 of the cabin opening 6 and the upper part 16 of the rear body opening 7 by bolts 31. The lower seal part 22, in which the lower cabin retainer member 25 and the lower rear body retainer member 28 are integrated, is installed to the lower part 19 of the cabin opening 6 and the lower part 20 of the rear body opening 7 by bolts 31.

[0039] After the upper seal portion 21 and the lower seal portion 22 are assembled to the cabin opening 6 and the rear body opening 7, the joint seal portion 23, which is an integrated lower cabin retainer member 25 and a lower rear body retainer member 28, is assembled to the cabin opening 6 and the rear body opening 7 by bolts 31 so as to bridge between the upper seal portion 21 and the lower seal portion 22. The overlapping portions of the upper seal portion 21 and the joint seal portion 23 are appropriately bonded to each other by an adhesive or the like. In addition, the overlapping portions of the lower seal portion 22 and the joint seal portion 23 are appropriately bonded to each other by an adhesive or the like. This makes it possible to accommodate variations in the shapes and positions of the cabin opening 6 and the rear body opening 7. The upper seal portion 21 and the lower seal portion 22 may be assembled after the joint seal portion 23 is assembled.

[0040] After the upper seal portion 21, the lower seal portion 22 and the connecting seal portion 23 are assembled to the cabin opening 6 and the rear body opening 7, the excess length of the upper seal portion 21 covering the side portions 17, 18 which are the longest areas of the inner surfaces 8, 11 of the cabin opening 6 and the rear body opening 7, i.e., the portion between the upper cabin retainer member 24 at the top of the upper seal portion 21 and the lower cabin retainer member 25 at the bottom of the upper seal portion 21 and the portion between the upper rear body retainer member 27 at the top of the upper seal portion 21 and the lower rear body retainer member 28 at the bottom of the upper seal portion 21, are adjusted by folding as appropriate.

[0041] After the excess length of the portions of the upper seal portion 21 covering the side portions 17, 18 has been adjusted, the side cabin retainer members 26 and the side rear body retainer members 29 are attached by bolts 31 to the upper seal portion 21 via the side portions 17, 18, i.e., the portions between the upper cabin retainer member 24 at the top of the upper seal portion 21 and the lower cabin retainer member 25 at the bottom of the upper seal portion 21, and the portions between the upper rear body retainer member 27 at the top of the upper seal portion 21 and the lower rear body retainer member 28 at the bottom of the upper seal portion 21. This makes it possible to accommodate variations in the shapes and positions of the side portions 17, 18, which are the longest ranges of the inner circumferential surfaces 8, 11 of the cabin opening 6 and the rear body opening 7.

[0042] The operation and effect of the sealing structure 1 between the cabin section 2 and the rear body section 3 of this embodiment will be described below. In a structure in which the inside of the cabin section and the inside of the rear body section communicate with each other, if the cabin section and the rear body section are made integrally, a large investment and dedicated design are required, so a structure in which an existing cabin section is partially used and the rear body section is made separately as a box-shaped, highly versatile body is adopted for small-volume production. On the other hand, in a structure in which the cabin section and the rear body section are made separately, a sealing structure is required that connects the cabin section and the rear body section without any gaps and seals the gap between the cabin section and the rear body section from rainwater and the like outside the automobile. However, as described above, there is variation in the positions at which the cabin section and the rear body section are mounted on the chassis, so a structure that takes this variation into consideration is required.

[0043] For example, in order to absorb the variation, a structure in which the hood member is held by a strong, rigid iron frame at the front and rear can be considered. However, this structure, like the coupling part of a railway car, is very heavy and requires a lot of time for assembly, so it is difficult to apply it to only small-scale production cars such as modified cars. In addition, with this structure, the iron frames at both the front and rear take up the space inside the car, making it difficult to effectively use the space inside the car.

[0044] On the other hand, according to this embodiment, in a sealing structure 1 between a cabin portion 2 and a rear body portion 3, which is provided with a hood member 5 that connects the cabin opening 6 of the cabin portion 2 and the rear body opening 7 of the rear body portion 3 while sealing the gap between the cabin opening 6 and the rear body opening 7, the hood member 5 is fixed at the cabin opening 6 between a cabin seal member 9 arranged on the inner surface 8 of the cabin opening 6 and a cabin retainer member 10 arranged at a position farther from the inner surface 8 of the cabin opening 6 than the cabin seal member 9, while sealing the gap between the inner surface 8 of the cabin opening 6 and the hood member 5.

[0045] Meanwhile, at the rear body opening 7, the hood member 5 is fixed while sealing the gap between the inner circumferential surface 11 of the rear body opening 7 and the hood member 5 by the rear body seal member 12 between the rear body seal member 12 arranged on the inner circumferential surface 11 of the rear body opening 7 and a rear body retainer member 13 arranged at a position farther from the inner circumferential surface 11 of the rear body opening 7 than the rear body seal member 12. Therefore, the gap between the cabin portion 2 and the rear body portion 3 can be sealed with a simple structure.

[0046] In addition, according to this embodiment, the hood member 5, the cabin seal member 9 and the rear body seal member 12 are integrated with each other as the seal portion 14, so that the seal portion 14 can be easily assembled to the cabin opening 6 and the rear body opening 7.

[0047] According to this embodiment, the upper seal portion 21 disposed on the tops 15, 16 and both side portions 17, 18 of the cabin opening 6 and the rear body opening 7, which is important for reliably sealing the gap between the cabin opening 6 and the rear body opening 7 from rainwater and the like outside the automobile, is integrally formed, thereby making it possible to reliably seal the gap between the cabin opening 6 and the rear body opening 7 from rainwater and the like outside the automobile. Also, by dividing the seal portion 14 into the upper seal portion 21, the lower seal portion 22, and the connecting seal portion 23 that bridges between the upper seal portion 21 and the lower seal portion 22, it is easy to accommodate variations in the shapes and positions of the cabin opening 6 and the rear body opening 7 when assembling the seal portion 14 to the cabin opening 6 and the rear body opening 7.

[0048] In addition, according to this embodiment, the lateral cabin retainer member 26, which fixes the longest range, is bridged between the upper cabin retainer member 24 and the lower cabin retainer member 25, so that it is easy to accommodate variations in the shape and position of the cabin opening 6 when assembling the hood member 5, cabin seal member 9 and cabin retainer member 10 to the cabin opening 6.

[0049] In addition, according to this embodiment, the lateral rear body retainer member 29, which fixes the longest range, is bridged between the upper rear body retainer member 27 and the lower rear body retainer member 28, making it easier to accommodate variations in the shape and position of the rear body opening 7 when assembling the hood member, rear body seal member 12 and rear body retainer member 13 to the rear body opening 7.

[0050] That is, in this embodiment, the cabin section 2 and the rear body section 3 are fastened from the inside of the vehicle compartment toward the outside by the hood member 5, the cabin retainer member 10 that holds the hood member 5, and the rear body retainer member 13, and are connected all around without any gaps, thereby reliably isolating the inside of the vehicle compartment from the outside of the vehicle compartment and absorbing variations in the shape and position of the cabin opening 6 and the rear body opening 7. The simple sealing structure 1 that connects the cabin section 2 and the rear body section 3 all around by the minimum number of hood members 5 corresponding to the necessary amount of variation absorption, the cabin retainer member 10 that holds the hood member 5, and the rear body retainer member 13, can make the sealing structure 1 lightweight and inexpensive. In addition, the sealing structure 1 of this embodiment is easy to assemble and can ensure mass productivity on a small-scale production basis. The sealing structure 1 of this embodiment can reduce the proportion of the space in the vehicle compartment.

[0051] Although the embodiment of the present invention has been described above, the present invention is not limited to the above embodiment and can be embodied in various forms. [Explanation of symbols]
