Summary of the Invention

Problems to be Solved by the Invention

[0004] By the way, in Patent Document 1, since the SCU is attached to the lower part of the floor panel, there is room for improvement in that the degree of freedom in layout of the underfloor space under the floor panel is restricted. In particular, in vehicles such as hybrid electric vehicles (HEV) and plug-in hybrid electric vehicles (PHEV), since a drive battery and exhaust system components are arranged under the floor, the arrangement space for the SCU under the floor is limited.

[0005] In this case, the SCU could be placed on the passenger compartment side of the floor panel, but the wire harness extending from the SCU would have to be routed through a hole in the floor panel to the underfloor, suspending the sensor, and then connecting that sensor to the exhaust pipe, making the assembly process complicated. Furthermore, there is a risk that the suspended sensor and wire harness could come into contact with and damage equipment such as trolleys on the manufacturing line.

[0006] Therefore, the present invention aims to provide a vehicle structure that allows in-vehicle equipment to be easily assembled to the floor panel without being restricted by space limitations. [Means for solving the problem]

[Modes for carrying out the invention]

[0010] Embodiments of the present invention will be described in detail below with reference to the drawings. In the following drawings, the symbol FR indicates the front of the vehicle, the symbol UP indicates the top of the vehicle, and the symbol LH indicates the right side in the vehicle width direction (right side in the direction of travel). The opposite direction of symbol FR is the rear of the vehicle, the opposite direction of symbol UP is the bottom of the vehicle, and the opposite direction of symbol LH is the left side in the vehicle width direction (left side in the direction of travel). Hereinafter, these directions may simply be referred to as front, rear, top, bottom, left side, and right side.

[0011] Figure 1 is a cross-sectional view along the vehicle width direction of the floor portion on the right side of the vehicle illustrating the vehicle structure according to this embodiment. Figure 2 is an enlarged view of section A in Figure 1. Figure 3 is a perspective view of the protruding portion 25 of the floor panel 11 as seen from the bottom side.

[0012] The vehicle structure according to this embodiment is applied to the floor portion of a vehicle 100 such as an automobile. The type of automobile to which the vehicle structure is applied is not limited and may include an internal combustion engine vehicle (ICEV), a hybrid electric vehicle (HEV), or a plug-in hybrid electric vehicle (PHEV). In this example, a vehicle equipped with a drive battery is used as an example for explanation.

[0013] As shown in Figures 1 to 3, the vehicle 100 to which the vehicle structure of this example is applied is equipped with a floor panel 11. The floor panel 11 extends substantially horizontally. The floor panel 11 is a plate material that constitutes the floor surface of the vehicle body of the vehicle 100, and is formed, for example, by pressing a steel plate.

[0014] Vehicle 100 includes an exhaust pipe 13, which extends in the vehicle longitudinal direction along the lower surface 11B of the floor panel 11. The exhaust pipe 13 allows the exhaust gas discharged from an engine (not shown) to pass through. The exhaust pipe 13 includes a catalyst (not shown) that purifies nitrogen oxides (NOx) and the like contained in the exhaust gas sent from the engine.

[0015] The floor panel 11 is equipped with an in-vehicle device, an SCU (Sensor Control Unit) 15. The SCU 15 measures the concentration of the substance to be measured in the exhaust gas based on the detection signal from a sensor (not shown) such as a PM sensor provided in the exhaust pipe 13. Note that the in-vehicle devices mounted on the floor panel 11 are not limited to the SCU 15, and may also be an ECU (Electronic Control Unit) that controls various devices, a harness terminal block, a harness connector, a junction box, a DC / DC converter, a DC / AC converter, etc.

[0016] The floor panel 11 is provided on the upper part of a side member 21 that constitutes the chassis frame of the vehicle 100. The chassis frame includes a pair of side members 21 (only the side member on the right side of the vehicle is shown in FIG. 1) and a plurality of cross members (not shown). The pair of side members 21 extend in the vehicle longitudinal direction with a gap in the vehicle width direction. The cross members extend in the vehicle width direction at a plurality of locations spaced in the vehicle longitudinal direction, and both ends in the vehicle width direction of each are joined to the side member 21.

[0017] Vehicle 100 has a side sill 23 that extends in the vehicle longitudinal direction outside the side member 21 in the vehicle width direction. The side member 21 and the side sill 23 are arranged at intervals from each other, and the floor panel 11 is joined to the side member 21 and the side sill 23.

[0018] Also, when the vehicle 100 is a hybrid vehicle or a plug-in hybrid vehicle, a driving battery 17 is disposed in the underfloor space Fs on the lower surface 11B side of the floor panel 11. This battery 17 is disposed in the underfloor space Fs between a pair of left and right side members 21 that are at the center in the vehicle width direction.

[0019] The floor panel 11 has a protruding portion 25 that protrudes upward. This protruding portion 25 is disposed between the side member 21 and the side sill 23 in the floor panel 11 in the vehicle width direction. And the SCU 15 is housed in this protruding portion 25 and is disposed above the lower surface 11B of the floor panel 11.

[0020] The floor panel 11 has an opening 31. The protruding portion 25 is a bracket 33 separate from the floor panel 11, and this bracket 33 is attached to the floor panel 11 from the upper surface 11U side of the floor panel 11. Thereby, the opening 31 of the floor panel 11 is covered by the bracket 33. And the SCU 15 mounted on the floor panel 11 is assembled to the bracket 33, and the bracket 33 is fastened and attached to the flat portion 11F of the upper surface 11U of the floor panel 11 from the vehicle compartment Vc side with bolts 35 in the state of the sub-assembly SA to which the SCU 15 is assembled.

[0021] On the lower surface 11B of the floor panel 11, mounting plates 41 are fixed along the opposing edge portions of the opening 31 by welding or the like. Nuts 43 are welded to the mounting plates 41, and these nuts 43 communicate with hole portions 45 formed in the vicinity of the edge portion of the opening 31 of the floor panel 11. Bolts 35 for fastening the bracket 33 are fastened to these nuts 43 of the mounting plates 41, and thereby, the bracket 33 is fixed to the upper surface 11U of the floor panel 11. Note that the nuts 43 to which the bolts 35 for fastening the bracket 33 are fastened may be directly welded to the floor panel 11 and the mounting plates 41 may be omitted.

[0022] The opening 31 in the floor panel 11 is formed in a position that overlaps with the exhaust pipe 13 when viewed from above. As a result, the SCU 15 housed in the protruding section 25 is positioned near the exhaust pipe 13. Note that the opening 31 in the floor panel 11 and the exhaust pipe 13 do not need to be positioned to overlap when viewed from above; they may be positioned not to overlap when viewed from above. In addition, a shielding plate 47 is provided at the bottom of the floor panel 11 between the opening 31 and the exhaust pipe 13. This shielding plate 47 is a plate material such as a heat shield (heat protector) mainly provided to block heat from the exhaust pipe 13. This shielding plate 47 extends to a position that overlaps with the SCU 15 housed in the protruding section 25 and the exhaust pipe 13 when viewed from above.

[0023] Next, we will describe the sub-assembly SA in which the SCU15 is assembled to the bracket 33. Figure 4 is a perspective view of the sub-assembly SA with the SCU15 assembled to the bracket 33, viewed from below (the side attached to the floor panel 11). Figure 5 is a plan view of the sub-assembly SA with the SCU15 assembled to the bracket 33, viewed from below (the side attached to the floor panel 11). Figure 6 is a side view of the sub-assembly SA with the SCU15 assembled to the bracket 33.

[0024] As shown in Figures 4 to 6, the bracket 33 has an upper plate portion 51, a side plate portion 53, and a flange portion 55. The bracket 33 is integrally formed, for example, by press-forming a steel plate. The upper plate portion 51 is the upper part of the bracket 33 and is formed in the shape of a flat plate extending in a substantially horizontal direction. The side plate portion 53 is the part that constitutes the circumferential surface of the bracket 33 and is connected to the outer peripheral edge of the upper plate portion 51 and extends downward. The flange portion 55 is the part that is fixed to the floor panel 11 and is connected to the lower edge of the side plate portion 53 and extends so as to protrude outward in the horizontal direction. Thus, the bracket 33 having the upper plate portion 51, the side plate portion 53, and the flange portion 55 is hat-shaped with the central portion recessed upwards, thereby increasing its rigidity. In this way, the bracket 33 with a recessed central portion has a recessed central portion whose size in plan view is equivalent to the opening 31 of the floor panel 11.

[0025] The bracket 33 has a flange portion 55 with multiple insertion holes 61 into which bolts 35 are inserted from above. The flange portion 55 also has a recessed portion 63 formed on its inner peripheral edge where the side plate portion 53 connects, which extends upward in the circumferential direction, and an annular sealing member 65 is fitted into this recessed portion 63. This sealing member 65 is made of, for example, a resin such as rubber.

[0026] SCU15 is fixed to the lower surface of the upper plate portion 51 of the bracket 33. SCU15 is fixed to the upper plate portion 51 via a fixing bracket 71. The upper plate portion 51 of the bracket 33 has stud bolts 73, and the fixing bracket 71 is fixed to the upper plate portion 51 by nuts 74 fastened to these stud bolts 73. The fixing bracket 71 has locking claws 75, and SCU15 is locked by the locking claws 75 and assembled to the fixing bracket 71. Note that the locking claws 75 are not shown in Figure 3.

[0027] The SCU15 is connected to a first wiring member 81 and a second wiring member 83. The first wiring member 81 is a sensor harness with a sensor at its tip that is connected to the exhaust pipe 13. The first wiring member 81 is pulled out through the opening 31 of the floor panel 11 to the lower surface 11B side of the floor panel 11, and the sensor at its tip is connected to the exhaust pipe 13. Detection signals from the sensor are transmitted to the SCU15 through the first wiring member 81. The second wiring member 83 is a control harness with its tip connected to a control device (not shown) such as the vehicle's ECU. The SCU15 transmits measurement signals to the control device through the second wiring member 83. This second wiring member 83 is pulled out to the upper side of the upper plate portion 51 through a hole (not shown) formed in the upper plate portion 51 of the bracket 33. As a result, the second wiring member 83 is pulled out from the protruding portion 25 of the bracket 33 to the vehicle compartment Vc and routed. A grommet 85 is fitted to the hole in the upper plate portion 51 through which the second wiring member 83 passes, and the grommet 85 seals the insertion point of the second wiring member 83 into the hole.

[0028] Next, we will describe the case in which the sub-assembly SA, with the SCU15 attached to the bracket 33, is attached to the floor panel 11.

[0029] First, the bracket 33 of the sub-assembly SA is positioned against the floor panel 11 from the passenger compartment Vc side so as to close the opening 31. At this time, in the sub-assembly SA, the first wiring member 81 extending from the SCU 15 is attached to the SCU 15 or the like with adhesive tape in a wound state, for example, and held in a state housed within the bracket 33.

[0030] After positioning the bracket 33 of the sub-assembly SA to cover the opening 31 of the floor panel 11, the through hole 61 formed in the flange portion 55 of the bracket 33 is connected to the hole 45 formed in the floor panel 11. A bolt 35 is then inserted into these connected through holes 61 and 45 and screwed into the nut 43 of the mounting plate 41 to fasten it. This fixes the bracket 33 of the sub-assembly SA to the floor panel 11. When the bracket 33 is fixed to the floor panel 11 in this way, the sealing member 65 of the bracket 33 comes into close contact with the upper surface 11U of the floor panel 11, thereby sealing the bracket 33 and the floor panel 11.

[0031] Next, on the underside of the floor panel 11, which is the lower surface 11B side, the first wiring member 81, which is held in place by being wrapped with adhesive tape within the bracket 33, is pulled downward through the opening 31, and the sensor at the tip of this first wiring member 81 is connected to the exhaust pipe 13.

[0032] As explained above, according to the vehicle structure of this embodiment, the SCU 15 is housed in a protruding portion 25 that extends upward from the floor panel 11 and is positioned above the lower surface 11B of the floor panel 11. Therefore, compared to a structure in which the SCU 15 is positioned on the lower surface 11B side of the floor panel 11, the installation position of the SCU 15 can be raised. This allows the SCU 15 to be easily assembled without being limited by the underfloor space Fs, and moreover, a large underfloor space Fs can be secured on the lower surface 11B side of the floor panel 11. Furthermore, even in a narrow underfloor space Fs with poor visibility, the assembly work of the SCU 15 to the floor panel 11 and the routing work of the first wiring member 81 can be performed without difficulty without damaging the SCU 15 or the first wiring member 81. Moreover, since the ground clearance of the SCU 15, which is the height of the SCU 15 from the road surface, can be increased, the amount of road surface interference countermeasures parts such as covers surrounding the SCU 15 can be reduced.

[0033] Furthermore, according to the vehicle structure of this embodiment, since the protruding portion 25 is a bracket 33 separate from the floor panel 11, the protruding portion 25 on which the SCU 15 is located can be easily provided on the floor panel 11 by assembling the bracket 33 on which the SCU 15 is provided so as to cover the opening 31 from the upper surface 11U side of the floor panel 11.

[0034] Furthermore, since the bracket 33 is assembled to the floor panel 11, the bracket 33 can be removed from the floor panel 11, making it easy to perform maintenance and replacement of the SCU 15 on the passenger compartment Vc side. In addition, various brackets 33 of different sizes and shapes can be used without being restricted by the molding of the floor panel 11, thereby easily accommodating changes in the size of the SCU 15. Moreover, a damaged bracket 33 can be easily replaced with a new bracket 33, and the strength can be increased by assembling a bracket 33 of a different thickness than the floor panel 11.

[0035] Furthermore, according to the vehicle structure of this embodiment, the first wiring member 81 connected to the SCU 15 can be easily pulled out from the opening 31 of the floor panel 11 and connected to the exhaust pipe 13.

[0036] Furthermore, according to the vehicle structure of this embodiment, since the SCU 15 is located near the exhaust pipe 13, the length of the first wiring member 81 pulled out from the opening 31 of the floor panel 11 can be shortened. This improves the ease of routing the first wiring member 81 and also improves sensing performance by shortening the routing length. In addition, since the routing length of the first wiring member 81 on the lower surface 11B side of the floor panel 11 can be shortened, the effects of pitching from the road surface can be suppressed.

[0037] Furthermore, according to the vehicle structure of this embodiment, the bracket 33 can be fixed to the floor panel 11 with high fixing strength by fixing the flange portion 55 on the periphery of the bracket 33 to the flat portion 11F of the floor panel 11.

[0038] Furthermore, according to the vehicle structure of this embodiment, the bracket 33 is formed in a hat shape having an upper plate portion 51 and a side plate portion 53 that extends downward from the outer peripheral edge of the upper plate portion 51 and is connected to the flange portion 55, so the rigidity of the bracket 33 itself can be increased.

[0039] Furthermore, according to the vehicle structure of this embodiment, since the SCU15 is fixed to the upper plate portion 51 of the bracket 33, the SCU15 can be positioned as high as possible and away from the exhaust pipe 13, thereby suppressing the influence of heat from the exhaust pipe 13.

[0040] Furthermore, according to the vehicle structure of this embodiment, since the shielding plate 47 extends to a position that overlaps the SCU 15 and the exhaust pipe 13 in the vertical direction, the shielding plate 47 can suppress the influence of heat from the exhaust pipe 13 on the SCU 15. In addition, the shielding plate 47 can suppress the influence of pitching from the road surface on the SCU 15.

[0041] In this example, the shielding plate 47 extends to a position where it overlaps vertically with respect to both the SCU 15 and the exhaust pipe 13. However, if the SCU 15 and the exhaust pipe 13 are positioned so that they do not overlap vertically, the shielding plate 47 may be positioned so that it overlaps vertically with respect to either the SCU 15 or the exhaust pipe 13.

[0042] Furthermore, according to the vehicle structure of this embodiment, the second wiring member 83 of the SCU15 is routed from the protruding portion 25 to the passenger compartment Vc, so the second wiring member 83 can be easily routed to the passenger compartment Vc. Therefore, it is not necessary to route the second wiring member 83 in the narrow underfloor space Fs where visibility is poor.

[0043] Furthermore, according to the vehicle structure of this embodiment, the protruding portion 25 is positioned between the side members 21 and the side sill 23, which extend in the longitudinal direction of the vehicle and are spaced apart from each other. Therefore, the protruding portion 25 housing the SCU 15 can be surrounded and protected by these side members 21 and the side sill 23. In addition, since the SCU 15 housed in the protruding portion 25 is positioned above the lower surface 11B of the floor panel 11, for example, when the side sill 23 is impacted by a side collision and displaced toward the side member 21, the downward movement of the SCU 15 is suppressed. Therefore, in a vehicle 100 with a battery 17 mounted in the underfloor space Fs, contact between the SCU 15 and the battery 17 due to impact can be suppressed.

[0044] In the above embodiment, the example described was that the size of the recessed portion of the bracket 33 in plan view is equivalent to the size of the opening 31 of the floor panel 11. However, the opening 31 of the floor panel 11 may be smaller than the size of the recessed portion of the bracket 33 in plan view, as long as it is large enough to allow the first wiring member 81 having the sensor to be removed without difficulty. By reducing the size of the opening 31 in this way, the intrusion of water and foreign matter from the road surface into the bracket 33 housing the SCU 15 can be further suppressed.

[0045] Thus, the present invention is not limited to the embodiments described above. It is also intended and within the scope of protection to be provided for the combination of each configuration of the embodiments, as well as for modifications and applications by those skilled in the art based on the description in the specification and well-known technology.

[0046] As described above, the following matters are disclosed in this specification: (1) Floor panels that make up the floor surface of the vehicle body, The in-vehicle equipment provided on the floor panel, Equipped with, The floor panel has a protruding portion that extends upward, The vehicle structure is such that the in-vehicle equipment is housed within the protruding portion and positioned above the lower surface of the floor panel. This vehicle structure allows for a higher mounting position for on-board equipment compared to structures where the equipment is placed on the underside of the floor panel. This makes it possible to easily assemble the equipment without being limited by the underfloor space, and also allows for a large amount of underfloor space to be secured on the underside of the floor panel. Furthermore, even in narrow underfloor spaces with poor visibility, the assembly of on-board equipment and the routing of wiring can be performed on the floor panel without damaging the equipment or wiring. In addition, since the ground clearance of the on-board equipment from the road surface can be increased, the amount of road surface interference prevention parts such as covers surrounding the equipment can be reduced.

[0047] (2) The floor panel has an opening, The vehicle structure according to (1), wherein the protruding portion is a bracket that covers the opening from the upper side of the floor panel. According to this vehicle structure, by assembling a bracket on which the onboard equipment is mounted so as to cover the opening from the upper side of the floor panel, a protruding portion on which the onboard equipment is located can be easily provided on the floor panel. Furthermore, because the bracket is assembled to the floor panel, the bracket can be easily removed from the floor panel to perform maintenance and replacement of in-vehicle equipment from inside the vehicle. In addition, various brackets of different sizes and shapes can be used without being restricted by the molding of the floor panel, thereby easily accommodating changes in the size of in-vehicle equipment. Moreover, damaged brackets can be easily replaced with new ones, and the strength can be increased by assembling brackets of a different thickness than the floor panel.

[0048] (3) The in-vehicle equipment is connected to the first wiring member, The vehicle structure according to (2), wherein the first wiring member is connected through the opening to an exhaust pipe disposed along the lower surface of the floor panel. This vehicle structure allows the first wiring component, which is connected to the onboard equipment, to be easily routed through an opening in the floor panel and connected to the exhaust pipe.

[0049] (4) The vehicle structure according to (3), wherein the onboard equipment is located near the exhaust pipe. This vehicle structure allows for a shorter length of the first wiring component pulled out from the opening in the floor panel. This improves the ease of routing the first wiring component and also enhances sensing performance by shortening the routing length. Furthermore, since the routing length of the first wiring component on the underside of the floor panel can be shortened, the effects of pitching from the road surface can be reduced.

[0050] (5) The bracket has a flange portion on its periphery, The vehicle structure according to any one of (2) to (4), wherein the flange portion is fixed to a flat portion on the upper surface of the floor panel. According to this vehicle structure, the bracket can be fixed to the floor panel with high fixing strength by fixing the peripheral flange portion to the flat surface of the floor panel.

[0051] (6) The vehicle structure according to (5), wherein the bracket has an upper plate portion and a side plate portion that extends downward from the outer peripheral edge of the upper plate portion and is connected to the flange portion. This vehicle structure allows for increased rigidity by using a hat-shaped bracket.

[0052] (7) The vehicle structure according to (6), wherein the in-vehicle equipment is fixed to the upper plate portion of the bracket. This vehicle structure allows onboard equipment to be positioned as high up as possible, away from the exhaust pipe, thereby minimizing the effects of heat from the exhaust pipe.

The vehicle structure according to any one of (3) to (7), wherein the shielding plate extends to a position that overlaps vertically with respect to at least one of the on-board equipment and the exhaust pipe. This vehicle structure allows for the reduction of heat from the exhaust pipe's impact on onboard equipment through the use of shielding plates. Furthermore, the shielding plates also reduce the impact of pitching from the road surface on onboard equipment.

[0054] (9) The in-vehicle equipment is connected to a second wiring member, The vehicle structure according to any one of (1) to (8), wherein the second wiring member is routed from the protruding portion into the passenger compartment. This vehicle structure allows for easy routing of the second wiring component, which is connected to the onboard equipment, into the passenger compartment.

[0055] (10) The vehicle structure according to any one of (1) to (9), wherein the protruding portion is located between a side member and a side sill, each extending in the longitudinal direction of the vehicle and spaced apart from one another. According to this vehicle structure, by positioning the on-board equipment between the side member and the side sill, the equipment can be enclosed and protected by these side members and the side sill. Furthermore, since the on-board equipment housed in the protruding section is positioned above the underside of the floor panel, if, for example, the side sill is impacted by a side collision and displaced toward the side member, the downward movement of the on-board equipment is suppressed. Therefore, in vehicles with batteries mounted in the underfloor space, contact between the on-board equipment and the battery due to impact can be suppressed. [Explanation of symbols]
