[0012] Hereinafter, an embodiment of a mounting structure for a vehicle generating unit according to the present invention will be described with reference to the drawings (FIGS. 1 to 6).

[0013] In the drawings, the direction of the arrow Fr indicates the front in the longitudinal direction of the vehicle. In the description of the embodiment, the "front (front end) and rear (rear end)" correspond to the front and rear in the longitudinal direction of the vehicle. The arrows R and L indicate the right and left sides in the vehicle width direction, respectively, and the "left and right" in this embodiment correspond to the "left side" and "right side" when the occupant faces forward of the vehicle.

[0014] The mounting structure for a vehicle power generating unit of this embodiment is a structure for mounting a power generating unit 10 on a unit installation structure provided at the rear of a vehicle body. The configuration of the power generating unit 10 in the mounting structure will be described below.

[0015] The power generating unit 10 of this embodiment is detachably mounted, for example, under the floor of a luggage space or the like provided at the rear of the vehicle, and has a generally rectangular parallelepiped shape extending in the vehicle width direction as a whole. In this case, the power generating unit 10 is fixed to the rear of the vehicle in a state where it is inserted into the vehicle from an opening provided at the rear of the vehicle. In this example, as shown in FIG. 1, the power generating unit 10 is disposed between the rear wheels 22 in the vehicle width direction.

[0016] Although detailed configuration of the power generating unit 10 is not illustrated, the power generating unit 10 has a power generating engine and a generator that generates electricity when driven by the power generating engine. The power generating unit 10 also has a fuel tank filled with fuel for driving the power generating engine, electrical equipment such as an inverter that receives power from the generator, and a cooling device for cooling the electrical equipment, the power generating engine, etc. The power generating unit 10 further includes a tray 11 and a top lid 12 for accommodating the above-mentioned equipment.

[0017] The bottom of the tray 11 is substantially rectangular extending in the vehicle width direction, and the above-mentioned generator engine, fuel tank, generator, cooling device, etc. are installed on the tray 11. As shown in FIG. 6, a side wall 15 is provided on the side of the tray 11 in the vehicle width direction, and a side flange 16 is provided on the upper part of the side wall 15, protruding outward in the vehicle width direction and extending in the vehicle front-rear direction. A handle 17 and the like are provided on the upper surface of the side flange 16 for use in installation work, transportation, etc. The top cover 12 is a substantially rectangular box shape that covers the tray 11 from above the vehicle, and is attached to the tray 11 so that the side of the top cover 12 is located, for example, slightly inside the handle 17. A hole 12a through which a harness, etc., passes is provided on the side of the top cover 12.

[0018] The side flanges 16 are mounted on rails 35 of the unit mounting structure, which will be described later. The relationship between the side flanges 16 and the rails 35 will be described later.

[0019] Next, the unit installation structure provided on the vehicle body side will be described. The unit installation structure has a box-shaped member (unit installation structure) 30, a rail 35, and suspension support members (suspension support members) 40A, 40B, 50A, and 50B. As shown in FIG. 4, the box-shaped member 30 is a substantially rectangular parallelepiped member extending in the vehicle width direction, and has a top surface portion 31a, a right side wall (side wall) 31b and a left side wall (side wall) 31c facing the vehicle width direction, and a front wall (inner wall portion) 31d facing the front of the vehicle, and an opening portion 31e is provided at the rear. The box-shaped member 30 is attached to the vehicle body via the suspension support members 40A, 40B, 50A, and 50B.

[0020] The rail 35 is a member extending in the front-rear direction of the vehicle, provided inside the box-shaped member 30, and configured to be able to protrude from the opening 31e to the outside of the vehicle. As shown in Figures 2 and 3, the rail 35 has a rail support portion 36 and a long movable rail portion 37. The rail support portion 36 is fixed to the inner surface of the left side wall 31c and the inner surface of the right side wall 31b, and although detailed illustration is omitted, supports the movable rail portion 37 by covering it from above and below and from the width direction intersecting the moving direction of the rail 35. In other words, the rail support portion 36 supports the movable rail portion 37 by covering it from above, below, left and right.

[0021] The movable rail portion 37 is configured to be movable in parallel in the longitudinal direction of the rail 35 (in this example, the vehicle front-rear direction) while being supported by the rail support portion 36. The movable rail portion 37 in this example has an outer rail 37A and an inner rail 37B. The outer rail 37A directly engages with the rail support portion 36, and is configured to be movable in parallel along the longitudinal direction of the rail 35 (in this example, the vehicle front-rear direction) relative to the rail support portion 36. When the outer rail 37A moves in parallel toward the rear of the vehicle relative to the rail support portion 36, the outer rail 37A protrudes from the opening 31e to the outside of the vehicle.

[0022] The outer rail 37A and the inner rail 37B are engaged with each other so as to be movable in parallel. The inner rail 37B is configured to be movable in parallel to the rear of the vehicle from a state where it overlaps with the outer rail 37A as viewed in the vehicle width direction. The inner rail 37B is also movable in parallel to the outer rail 37A regardless of the position of the outer rail 37A. For example, when the outer rail 37A is located inside the opening 31e, i.e., inside the box-shaped member 30, it is also possible for only the inner rail 37B to protrude from the opening 31e to the rear of the vehicle. When the outer rail 37A protrudes from the opening 31e to the rear of the vehicle and the inner rail 37B protrudes to the rear of the vehicle relative to the outer rail 37A, the movable rail portion 37 is in a maximum protruding state in which the length of protrusion from the opening 31e is the longest.

[0023] The inner rail 37B is provided with a pedestal 38 on which the above-mentioned side flange 16 is placed. The pedestal 38 is a long member with an L-shaped cross section that is joined to the inner rail 37B and extends in the front-rear direction of the vehicle, as shown, for example, as diagrammatically in Fig. 6. The pedestal 38 is fixed to the inner rail 37B and can move in parallel integrally with the inner rail 37B.

[0024] The power generation unit 10 is detachably mounted inside the box-shaped member 30 by moving the rail 35 inside the box-shaped member 30 while being installed on the rail 35 protruding outside the vehicle. In detail, the side flange 16 provided on the tray 11 of the power generation unit 10 is placed (installed) on the upper part of the movable rail part 37 in the maximum protruding state. At this time, the upper part of the base 38 of the inner rail 37B of the movable rail part 37 and the lower surface of the side flange 16 are fixed, and in this state, the movable rail part 37 moves in parallel to the inside of the opening 31e, so that the power generation unit 10 moves inside the opening 31e. The inner rail 37B of the movable rail part 37 moves in parallel to the front of the vehicle until it overlaps with the outer rail 37A in a side view, and after the inner rail 37B overlaps with the outer rail 37A, the inner rail 37B and the outer rail 37A move in parallel to the front of the vehicle toward the inside of the opening 31e together. When the inner rail 37B and the outer rail 37A reach the inside of the box-shaped member 30, the power generation unit 10 is housed inside the box-shaped member 30. In this state, the power generation unit 10 is fixed by a stopper member or the like (not shown) and is mounted inside the box-shaped member 30.

[0025] Next, a description will be given of the suspension support members 40A, 40B, 50A, and 50B that support the box-shaped member 30. The suspension support members 40A, 40B, 50A, and 50B each have a rear support member (first support portion) 40A, 40B and a front support member (second support portion) 50A, 50B.

[0026] As shown in Figs. 2 to 4, the rear support members 40A, 40B are fixed to the outer surface of the right side wall 31b and the outer surface of the left side wall 31c of the box-shaped member 30. The rear support members 40A, 40B are disposed on the vehicle lower side from the center in the vehicle up-down direction on the left and right outer surfaces. In this example, the rear support members 40A, 40B are disposed on the rear lower part of the outer surface of the right side wall 31b and the outer surface of the left side wall 31c. The right and left rear support members 40A, 40B are fixed to the corresponding rear side members 23. In this example, the rear support members 40A, 40B are joined to the lower surface of the rear side member 23.

[0027] The right and left rear support members 40A, 40B are joined to the outer surface of the right side wall 31b and the outer surface of the left side wall 31c of the box-shaped member 30, and are also joined to the corresponding rear side members 23. The right and left rear support members 40A, 40B have a strut member 41, a shaft member 46, a joint surface portion (first joint surface portion) 42, a flat plate portion (first flat plate portion) 43, an upper cushion member (first upper cushion member) 44, and a lower cushion member (first lower cushion member) 45.

[0028] The support member 41 is a hollow member having a substantially rectangular parallelepiped shape extending in the vehicle vertical direction. An upper portion of the support member 41 is joined to the lower surface of the rear side member 23. A shaft member 46 is fixed to the lower surface of the support member 41 in a state in which it penetrates through the lower surface. The joint surface portion 42 is a plate-shaped portion extending in the vehicle vertical direction and joined to the outer surfaces of the right side wall 31b and the left side wall 31c by spot welding or the like. The flat plate portion 43 is a plate-shaped portion protruding outward in the vehicle width direction from the middle portion of the joint surface portion 42 in the vehicle vertical direction. That is, the flat plate portion 43 of the right rear support member 40A protrudes outward to the right from the right side wall 31b, and the flat plate portion 43 of the left rear support member 40A protrudes outward to the left from the left side wall 31c.

[0029] In this embodiment, two metal flat plates having a predetermined thickness are each bent into an L shape, and one surface of each L-shaped plate member is joined to each other to form flat plate portion 43, and the other surface is aligned vertically across the vehicle and joined to right side wall 31b or left side wall 31c to form joint surface portion 42. A through hole is provided in approximately the center of flat plate portion 43, and shaft member 46 is fixed in a state of passing through the through hole.

[0030] The upper cushion member 44 is a member made of a resin material having a predetermined elastic modulus, is cylindrical with a predetermined thickness, and has a through hole in the center in the radial direction. The upper cushion member 44 is installed on the upper surface of the flat plate portion 43 with the shaft member 46 passing through the through hole. In this example, the upper cushion member 44 is disposed between the upper surface of the flat plate portion 43 and the lower surface of the support member 41.

[0031] The lower cushion member 45 is a member formed from a resin material having a predetermined elastic modulus, similar to the upper cushion member 44, and is cylindrical with a predetermined thickness, with a through hole provided in the radial center. The lower cushion member 45 is installed on the lower surface of the flat plate portion 43 with the shaft member 46 passing through the through hole.

[0032] In this embodiment, there are two front support members 50A, 50B. The two front support members 50A, 50B are fixed to the outer surface of the front wall 31d facing the front of the vehicle with a gap between them in the vehicle width direction. The right front support member 50A and the left front support member 50B are fixed to, for example, a rear cross member which is a vehicle body frame member. In this example, the front support members 50A, 50B are joined to the lower surface of the rear cross member.

[0033] The right and left front support members 50A, 50B are configured in a manner substantially similar to the rear support members 40A, 40B, as shown in Figures 2 to 4. The right and left front support members 50A, 50B have the same structure, and each has a support member 51, a shaft member 56, a joint surface portion (second joint surface portion) 52, a flat plate portion (second flat plate portion) 43, an upper cushion member (second upper cushion member) 54, and a lower cushion member (second lower cushion member) 55.

[0034] An upper portion of the support pillar member 51 of the front support members 50A, 50B is joined to the lower surface of the rear cross member, and a joint surface portion 52 is joined to the outer surface of the front wall 31d of the box-shaped member 30. Similarly to the rear support members 40A, 40B, the upper cushion member 54 and the lower cushion member 55 of each of the front support members 50A, 50B are disposed so as to sandwich the flat plate portion 53 from above and below, and are fixed by shaft members 56 or the like.

[0035] In this embodiment, the right and left rear support members 40A, 40B are disposed below the vehicle with respect to the right and left front support members 50A, 50B. For example, as shown in FIG. 4, the joint surface portion 42 and the flat plate portion 43 of the right rear support member 40A are disposed below the vehicle with respect to the joint surface portion 52 and the flat plate portion 53 of the right front support member 50A. With this configuration, when the power generation unit 10 is pulled out from the opening 31e, that is, when the movable rail portion 37 is in the maximum protruding state, the rail 35 is deformed in a cantilever state, and the rear end of the inner rail 37B is positioned below the vehicle with respect to the front end of the outer rail 37A. The dashed line in FIG. 5 shows a state in which the tip (rear end) of the movable rail portion 37 is displaced toward the vehicle lower side.

[0036] Since the front support members 50A, 50B and the rear support members 40A, 40B are both joined to the frame members of the vehicle body, a cantilever load acts on the rear support members 40A, 40B with the front support members 50A, 50B as the rotation center axis. In consideration of this, when the front support members 50A, 50B and the rear support members 40A, 40B are at the same vehicle up-down position, the flat plate portion 43 only deforms the lower cushion member 45 downward in plan, whereas when the rear support members 40A, 40B are at a lower position than the front support members 50A, 50B, the flat plate portion 43 of the rear support members 40A, 40B compresses, for example, the rear portion of the lower cushion member 45. As a result, the rear end of the rail 35 (particularly the inner rail 37B) protruding from the opening 31e toward the rear of the vehicle moves more toward the vehicle downward side. In addition, when the rear support members 40A, 40B are located higher on the vehicle than the front support members 50A, 50B, the front portions of the lower cushion members 45 of the rear support members 40A, 40B are compressed, so that the movement of the rear end of the inner rail 37B toward the lower side of the vehicle is relatively small.

[0037] By positioning the rear end of the inner rail 37B lower than the front end of the outer rail 37A, it becomes easier to maintain the power generation unit 10 in an extended state, resulting in improved visibility of the power generation unit 10 from above the vehicle. The improved visibility improves the ease of maintenance and refueling of the power generation unit 10.

[0038] In this embodiment, the elastic modulus of the lower cushion member 45 of the rear support members 40A, 40B is set to be smaller than the elastic modulus of the upper cushion member 44 of the rear support members 40A, 40B. With this configuration, it is possible to directly create a stroke toward the vehicle downward side caused by the application of a large cantilever load. Furthermore, since the elastic characteristics are different between the top and bottom, it is possible to achieve both a reduction effect on low-frequency vibration and high-frequency vibration.

[0039] In addition, in this embodiment, since the right and left front support members 50A, 50B are provided on the front wall 31d, the movable rail portion 37 can rotate downward around the right and left front support members 50A, 50B as the rotation center axis. As a result, the displacement of the rear end of the inner rail 37B becomes simpler, and the rail 35 can easily deform as intended.

[0040] Furthermore, in this embodiment, since the front support members 50A, 50B clamp the flat plate portion 53 between the upper cushion member 54 and the lower cushion member 55, the deformation of the cushion members 54, 55 is simpler, and the state of the rail 35 etc. after deformation can be more easily stabilized.

[0041] In addition, since the power generation unit 10 of this embodiment has the side flanges 16 installed on the rails 35, a load due to the weight of the power generation unit 10 acts on the inner rails 37B, etc. At this time, the inner rails 37B and the outer rails 37A are twisted, and the right and left inner rails 37B located at the rear are deformed so that the distance between them in the vehicle width direction increases toward the bottom of the vehicle. As a result, the upper parts of the outer rails 37A and the inner rails 37B lower toward the bottom of the vehicle toward the rear of the vehicle. Therefore, the rear end of the inner rails 37B is reliably deformed toward the bottom of the vehicle as described above.

[0042] As shown in Fig. 6, a plurality of holes are formed in the upper part of the base 38 fixed to the inner rail 37B of the movable rail portion 37 of this embodiment. These holes are arranged at intervals from one another in the longitudinal direction of the rail 35 (the vehicle front-rear direction). Furthermore, a plurality of protrusions 18 that protrude downward from the vehicle are provided on the side flange 16 of the power generation unit 10 of this embodiment. The protrusions 18 are arranged at intervals from one another in the vehicle front-rear direction so as to correspond to the holes 38a provided in the base 38 of the inner rail 37B. In this example, the protrusions 18 are formed by fixing the lower part of the handle 17 in a state in which it penetrates the side flange 16.

[0043] The power generating unit 10 is fixed to the rail 35 by inserting the protrusions 18 of the side flanges 16 into holes 38a of the bases 38 of the rails 35. To install the power generating unit 10, an operator grasps the handles 17 and installs the power generating unit 10 on the upper part of the outer rail 37A and the inner rail 37B that are in the maximum protruding state. At this time, since the protrusions 18 are provided on the lower part of the handles 17, the installation work in the holes 38a is facilitated. In addition, by forming a threaded portion on the protrusions 18, the protrusions 18 that pass through the holes 38a can be tightened with a nut or the like, thereby making it possible to more stably fix the power generating unit 10 to the rails 35.

[0044] In this embodiment, a widthwise gap and a vertical gap are formed between the rail support portion 36 and the movable rail portion 37, and the vertical gap is set to be larger than the widthwise gap. This makes it possible to stabilize the state in which the rear end of the inner rail 37B is located below the vehicle.

[0045] The description of the present embodiment is merely an example for explaining the present invention, and does not limit the invention described in the claims. Furthermore, the configuration of each part of the present invention is not limited to the above embodiment, and various modifications are possible within the technical scope described in the claims.

[0046] For example, in this embodiment, the front support members 50A, 50B are provided on the front wall 31d of the box-shaped member 30, but this is not limited thereto. The front support members 50A, 50B may be provided on the right side wall 31b and the left side wall 31c, which are closer to the front of the vehicle than the rear support members 40A, 40B. The front support members 50A, 50B may also be provided on the top surface portion 31a.

[0047] In the present embodiment, the power generating unit 10 is inserted from the rear of the vehicle, but the present invention is not limited thereto. For example, the power generating unit 10 may be inserted in the width direction from the side of the vehicle body. In this case, the opening of the box-shaped member may be disposed on the outer side in the vehicle width direction, and members corresponding to the rear support members 40A, 40B may be attached to the outer sides of the front and rear sides of the box-shaped member in the vehicle width direction, and a member corresponding to the front support member 50 may be attached to, for example, the inner wall of the box-shaped member 30 in the vehicle width direction.
