Description

Technical Field

[0001] The present invention relates to a structure of an electric vehicle in which electrical components are arranged on a floor tunnel. Background Art

[0002] In recent years, with the electrification of automobiles, the number of electrical components arranged in the vehicle interior has increased (for example, refer to Japanese Unexamined Patent Application Publication No. 2011-229284). Summary of the Invention

[0003] In addition, in recent years, the electrification of vehicles traveling on off-road roads has been continuously developing. Such off-road electric vehicles sometimes perform river-crossing driving. Therefore, the electrical components are arranged on the floor tunnel in such a way that they will not be submerged during river-crossing driving. However, during river-crossing driving, the water that enters the vehicle interior flows relative to the vehicle, and thus there is a case where the water splashes and falls on the electrical components arranged on the floor tunnel.

[0004] Therefore, an object of the present disclosure is to suppress water from falling on the electrical components arranged on the floor tunnel during river-crossing driving.

[0005] The electric vehicle of the present disclosure includes: electrical components arranged on a floor tunnel; and a rectifying plate extending obliquely downward rearward of the vehicle from the rear of the electrical components. The electric vehicle is characterized in that the rectifying plate has a ridge portion extending in the vehicle front-rear direction on the lower surface.

[0006] Thereby, the water that enters the vehicle interior during river-crossing driving is rectified by the ridge portion provided on the rectifying plate and flows rearward. Therefore, it is possible to suppress the undulation of the water surface of the water that enters the vehicle interior, and it is possible to suppress the water from falling on the electrical components arranged on the floor tunnel due to the undulation.

[0007] In the electric vehicle of the present disclosure, it may be that the left and right side end portions of the rectifying plate are inclined toward the center in the vehicle width direction as they go to the rear of the vehicle and are connected to a rear end portion extending in the vehicle width direction, and the left and right side end portions are provided with flanges extending downward.

[0008] Thereby, the water flowing along the lower surface of the rectifying plate is concentrated in the central portion at the rear of the rectifying plate and flows out from the central portion to the rear of the vehicle. Therefore, it is possible to set the position where the fluctuation of the water that enters the vehicle interior occurs to the rear of the vehicle separated from the electrical components. Thereby, it is possible to suppress the water from falling on the electrical components due to the undulation.

[0009] In the electric vehicle of the present disclosure, it is also possible to include a console box that houses the electrical component and the rectifying plate therein. The console box includes: a main body that is mounted on the upper portion of the floor passage and houses the electrical component therein; and a cable cover that is disposed adjacent to the rear of the main body and houses the rectifying plate therein. The cable cover has ribs that protrude toward the rectifying plate and extend in the vehicle width direction on the surface facing the rectifying plate.

[0010] Thereby, it is possible to suppress water that has wound between the rectifying plate and the cable cover from flowing toward the front of the vehicle and flowing into the electrical component.

[0011] In the electric vehicle of the present disclosure, it is also possible that the electrical component is housed in an element housing, the element housing is mounted on the upper portion of the floor passage, the rectifying plate is mounted on the upper rear portion of the element housing, and extends obliquely downward to the rear of the vehicle from the element housing.

[0012] Thereby, it is possible to suppress water that has entered the vehicle interior from falling onto the electrical component.

[0013] The present disclosure can suppress water from falling onto the electrical component disposed on the floor passage during river crossing driving. BRIEF DESCRIPTION OF THE DRAWINGS

[0023] The console box 20 is mounted on the floor tunnel 12. The console box 20 is an interior component that houses small items inside. The console box 20 includes a main body 21, an end plate 25, and a cable cover 28. As will be described later, the main body 21 is mounted on the upper surface 12A of the floor tunnel 12 via the inverter housing 40 disposed inside. The inverter 50 is mounted inside the inverter housing 40. The rectifier plate 30 is housed inside the cable cover 28. The rectifier plate 30 is mounted at the upper rear of the inverter housing 40 and extends obliquely downward to the rear of the vehicle from the inverter housing 40. The high-voltage cable 60 is connected to the inverter 50. The high-voltage cable 60 is housed inside the cable cover 28 and extends toward the rear of the vehicle from the inverter 50. In addition, a floor trim 14 is mounted between the cable cover 28 and the rear floor panel 13.

[0024] As Figure 2As shown, the converter housing 40 is made of metal and includes a housing portion 41, a lower bracket 42, and an upper bracket 43. The housing portion 41 has a square box shape that is open at the front and rear. Inside the housing portion 41, on the bottom surface, a converter 50, which is an electrical component, is installed. The lower bracket 42 is legs that are installed on the front and rear lower surfaces of the housing portion 41 and extend downward. The lower bracket 42 is installed on the upper surface 12A of the floor channel 12 by fastening components such as bolts. The upper bracket 43 is installed on the upper surface of the housing portion 41. The upper bracket 43 includes a pedestal portion 44 for fastening the main body 21 of the console box 20 and a tongue portion 46 for fastening the rectifier plate 30. The pedestal portion 44 has a cap-shaped cross section that protrudes upward, and a threaded hole 45 is provided in the web. The tongue portion 46 is a plate member that extends in a crank shape toward the rear of the vehicle in the center portion in the vehicle width direction of the pedestal portion 44. The tongue portion 46 is disposed at the rear upper part of the converter housing 40. A bolt hole 47 is provided in the tongue portion 46. In addition, a fixing nut 73 (refer to Figure 6 ) is set on the lower surface of the tongue portion 46.

[0025] The converter 50 installed in the housing portion 41 is provided with a connection terminal 51 at the rear end. The connector 61 of the high-voltage cable 60 is connected to the connection terminal 51. The high-voltage cable 60 extends toward the rear of the vehicle above the floor channel 12 from the rear end of the converter 50.

[0026] As described before, the console box 20 is composed of a main body 21, an end plate 25, and a cable cover 28. The main body 21 is installed on the upper surface 12A of the floor channel 12. The main body 21 has a box portion 22 made of resin for storing small items. An arm portion 23 that extends obliquely downward is provided at the rear end of the box portion 22. A bolt hole 24 is provided in the arm portion 23.

[0027] The end plate 25 is a component installed on the upper part of the rear end of the main body 21. The end plate 25 is made of resin and is provided with an air outlet 26 for blowing out air-conditioning air toward the rear. The cable cover 28 is made of resin and is disposed adjacent to the main body 21 at the lower part behind the main body 21. The cable cover 28 has a rib 28A (refer to Figure 6 ) that protrudes toward the rectifier plate 30 and extends in the vehicle width direction on the lower surface facing the rectifier plate 30.

[0028] As Figure 3 , Figure 4 shown, the rectifier plate 30 includes a plate portion 31 and a fastening portion 38 that protrudes toward the front of the vehicle from the plate portion 31. The plate portion 31 extends obliquely downward and rearward from the fastening portion 38. The plate portion 31 is divided by a front end portion 34, left and right side end portions 35, 36, and a rear end portion 37. The left and right side end portions 35, 36 incline toward the center in the vehicle width direction as they go toward the rear of the vehicle and are connected to the rear end portion 37. The rear end portion 37 extends in the vehicle width direction. As Figure 5As shown, the left and right side ends 35, 36 are provided with left and right flanges 35A, 36A extending downward. In addition, a bolt hole 39 is provided in the fastening portion 38.

[0029] As Figure 4 shown, a plurality of rib portions 32 extending in the vehicle front-rear direction are provided on the lower surface 31A of the plate-like portion 31. As Figure 5 shown, the rib portion 32 protrudes downward from the lower surface 31A of the plate-like portion 31.

[0030] As Figure 6 shown, a pin seat 29 is provided on the inner surface of the cable cover 28. The rear portion of the rectifying plate 30 is mounted on the inner surface of the cable cover 28 by a pin 75.

[0031] Next, with reference to Figure 2 and Figure 3 the assembly sequence of the console box 20 will be described. First, as Figure 2 shown, align the bolt hole 24 of the arm portion 23 of the main body 21 with the threaded hole 45 of the pedestal portion 44 provided on the converter housing 40. Then, fix the arm portion 23 to the pedestal portion 44 with a bolt 71. Thus, the main body 21 is mounted on the floor tunnel 12.

[0032] Next, connect the cable cover 28 to the rear end of the main body 21 and also connect it above the floor tunnel 12. Thus, the position of the bolt hole 39 of the fastening portion 38 of the rectifying plate 30 is aligned with the position of the bolt hole 47 of the tongue portion 46 of the converter housing 40. Pass a bolt 72 through the bolt holes 47, 39 and screw the bolt 72 into the fixing nut 73 (refer to Figure 6 ) to fasten the front fastening portion 38 of the rectifying plate 30 to the tongue portion 46. When the fastening portion 38 is fastened to the tongue portion 46, the rectifying plate 30 extends obliquely downward and rearward from the tongue portion 46 disposed at the upper rear of the converter housing 40.

[0033] Next, connect the front end of the end plate 25 to the rear end of the main body 21 and connect the lower end of the end plate 25 to the upper end of the cable cover 28.

[0034] In this way, the main body 21 is mounted on the upper surface 12A of the floor tunnel 12 via the converter housing 40 disposed inside. And, since the converter 50 is mounted inside the converter housing 40, when the main body 21 is mounted on the floor tunnel 12, the converter 50 is housed inside the main body 21. The rectifying plate 30 is housed inside the cable cover 28 and extends obliquely downward and rearward from the upper rear of the converter housing 40. In addition, as Figure 6As shown, the rib 28A of the cable cover 28 protrudes toward the upper surface of the rectifying plate 30. Further, when the cable cover 28 is installed above the floor passage 12, the high-voltage cable 60, the connector 61, and the connection terminal 51 are housed in the cable cover 28. Further, the rectifying plate 30 covers the high-voltage cable 60, the connector 61, and the connection terminal 51 from above.

[0035] As Figure 6 shown, the high-voltage cable 60 extends rearward of the vehicle above the floor passage 12 and extends rearward of the vehicle from the rear end of the cable cover 28. Further, the high-voltage cable 60 extends upward from the front surface of the rear floor panel 13 toward the upper surface 13A of the rear floor panel 13 through between the floor panel 11 and the floor trim 14. Further, it extends rearward of the vehicle between the upper surface 13A of the rear floor panel 13 and the rear seat 15.

[0036] Next, referring to Figure 4 、 Figure 6 the water flow with respect to the passenger compartment 10 when the electric vehicle 100 travels across a river will be described.

[0037] Figure 6 The double-dot dash line 91 shown indicates the water level of the water that enters the passenger compartment 10 during river-crossing travel. As shown by the double-dot dash line 91, the water level during river-crossing travel is lower than the converter 50, and the converter 50 will not be submerged by water.

[0038] On the other hand, Figure 6 the single-dot dash line 92 shown indicates the water level when the electric vehicle 100 accelerates during river-crossing travel. When the electric vehicle 100 accelerates, the water is pushed toward the rear of the passenger compartment 10, so the water level at the rear of the passenger compartment 10 becomes higher. Further, since the momentum of the water flow becomes larger, waves are generated on the water surface as shown by the curved arrow 93 in Figure 6 . As Figure 4 、 Figure 5 shown, a rib portion 32 extending in the vehicle front-rear direction is provided on the lower surface 31A of the plate-like portion 31. As shown by the arrow 90 in Figure 4 , the waves generated on the water surface are rectified by the rib portion 32 and flow toward the rear of the vehicle, so it is possible to suppress the waves hitting the lower surface 31A of the plate-like portion 31 from flowing backward toward the front of the vehicle. Thereby, it is possible to suppress water from falling onto the converter 50.

[0039] Further, as Figure 4As shown by arrow 90A in [description], the water that hits the lower surface 31A of the plate-like portion 31 is guided by the flanges 35A and 36A of the left and right side end portions 35 and 36 and gathers toward the center in the vehicle width direction. Then it flows out from the rear end portion 37. In this way, the water flowing along the lower surface 31A of the plate-like portion 31 is concentrated in the central portion at the rear of the plate-like portion 31 and flows out from the central portion toward the rear of the vehicle. Therefore, the position where the water that enters the passenger compartment 10 fluctuates can be made to be the rear of the vehicle separated from the converter 50. Thereby, it is possible to suppress the water from falling onto the converter 50 due to fluctuations.

[0040] In addition, as Figure 6 shown by the curved arrow 94 in [description], sometimes a part of the water flowing out from the rear end portion 37 of the rectifying plate 30 wraps around between the plate-like portion 31 and the cable cover 28 and flows toward the front of the vehicle. The water flow toward the front of the vehicle is blocked by the rib 28A provided on the cable cover 28. Therefore, it is possible to suppress the water that wraps around between the plate-like portion 31 and the cable cover 28 from falling onto the converter 50.

[0041] As described above, the electric vehicle 100 can suppress water from falling onto the converter 50 disposed on the floor tunnel 12 during river crossing driving.

[0042] In the above description, the electrical component is described as the converter 50, but it is not limited thereto. For example, the electrical component can be a control device such as an ECU, or a storage battery, etc.
