Description

[Technical Field]

[0001] The present invention relates to a configuration of an electric vehicle in which electrical components are arranged above a floor tunnel. [Background technology]

[0002] In recent years, with the trend toward electrification of automobiles, the number of electrical components arranged inside the vehicle cabin has increased (see, for example, Patent Document 1). [Prior art documents] [Patent documents]

[0003] [Patent Document 1] Japanese Patent Application Laid-Open No. 2011-229284 Summary of the Invention [Problem to be solved by the invention]

[0004] In recent years, the electrification of off-road vehicles has been increasing. Such off-road electric vehicles may need to cross rivers, and electrical components are therefore arranged above the floor tunnel to prevent them from becoming submerged when crossing a river. However, when crossing a river, water may enter the vehicle cabin and flow toward the vehicle, causing the water to splash up and splash onto the electrical components arranged above the floor tunnel.

[0005] Therefore, an object of the present disclosure is to prevent water from splashing on electrical components arranged above the floor tunnel when crossing a river. [Means for solving the problem]

[0006] The electric vehicle disclosed herein is an electric vehicle comprising an electrical component arranged above a floor tunnel and a straightening plate extending diagonally downward from the rear of the electrical component toward the rear of the vehicle, characterized in that the straightening plate has a protrusion portion on its underside that extends in the fore-and-aft direction of the vehicle.

[0007] As a result, water that enters the vehicle cabin when crossing a river is straightened by the protrusions on the baffle plate and flows rearward, preventing the water surface from becoming choppy once it enters the vehicle cabin and preventing the water from splashing onto electrical components located above the floor tunnel due to choppy water.

[0008] In the electric vehicle of the present disclosure, the right and left side ends of the straightening plate are connected to a rear end that extends in the vehicle width direction, inclining toward the center of the vehicle width direction as they move toward the rear of the vehicle, and the left and right side ends may have flanges that extend downward.

[0009] This allows water flowing along the underside of the air straightening vane to be collected in the center behind the vane and then flow out from the center toward the rear of the vehicle, so that the position where rippling occurs in the water that has entered the passenger compartment is at the rear of the vehicle, away from the electrical components, thereby preventing water from splashing onto the electrical components due to rippling.

[0010] The electric vehicle of the present disclosure may include a console box that houses the electrical components and the air straightening plate inside, and the console box may include a main body that is attached to the top of the floor tunnel and houses the electrical components inside, and a cable cover that is arranged adjacent to the rear of the main body and houses the air straightening plate inside, and the cable cover may include a rib on the surface facing the air straightening plate that protrudes toward the air straightening plate and extends in the vehicle width direction.

[0011] This prevents water that has gotten between the air deflector and the cable cover from flowing toward the front of the vehicle and into electrical components.

[0012] In the electric vehicle of the present disclosure, the electrical components may be housed in a component case, the component case may be attached to the upper part of the floor tunnel, and the air deflector may be attached to the upper rear of the component case and extend from the component case diagonally downward toward the rear of the vehicle.

[0013] This prevents water that has entered the vehicle interior from splashing on electrical components. [Effects of the Invention]

[0014] The present disclosure can prevent water from splashing on electrical components arranged above the floor tunnel when crossing a river. [Brief explanation of the drawings]

[0016] An electric vehicle 100 according to an embodiment will be described below with reference to the drawings. The electric vehicle 100 will be described as a battery electric vehicle (hereinafter referred to as a BEV), but may also be a hybrid vehicle that runs on an engine and a motor. As shown in FIG. 1, the electric vehicle 100 includes a passenger compartment 10, a console box 20, an inverter case 40 which is a component case, an inverter 50 which is an electrical component, a rectifier plate 30, and a high-voltage cable 60. Note that FR, UP, and RH shown in each drawing indicate the front, upper, and right sides of the electric vehicle 100, respectively. The opposite directions of FR, UP, and RH indicate the rear, lower, and left sides. Hereinafter, when the terms "front-rear," "left-right," and "up-down" are used in the description, they will refer to the front-rear direction of the electric vehicle 100, the left-right direction, and the up-down direction, unless otherwise specified.

[0017] The vehicle interior 10 includes a floor panel 11, a floor tunnel 12, and a rear floor panel 13. The floor panel 11 is a plate member that constitutes the floor of the vehicle interior 10. The floor tunnel 12 is located in the center of the vehicle width direction of the vehicle interior 10 and protrudes upward from the upper surface 11A of the floor panel 11. The floor tunnel 12 has a groove-shaped cross section that is open at the bottom and extends toward the rear of the vehicle from a dash panel (not shown) at the front of the vehicle interior to the front of the rear floor panel 13. The rear floor panel 13 is a pedestal-shaped portion that rises upward from the floor panel 11 behind the floor tunnel 12. Left and right front seats (not shown) are attached to the floor panels 11 on both sides of the floor tunnel 12. A rear seat 15 is attached above the rear floor panel 13. The area above the upper surface 11A of the floor panel 11, the area above the upper surface 12A of the floor tunnel 12, and the area above the upper surface 13A of the rear floor panel 13 form the area inside the vehicle cabin.

[0018] A console box 20 is attached above the floor tunnel 12. The console box 20 is an interior component that stores small items inside. The console box 20 is composed of a main body 21, an end panel 25, and a cable cover 28. As will be described later, the main body 21 is attached to the upper surface 12A of the floor tunnel 12 via an inverter case 40 disposed inside. An inverter 50 is attached inside the inverter case 40. A rectifying plate 30 is housed inside the cable cover 28. The rectifying plate 30 is attached to the upper rear of the inverter case 40 and extends from the inverter case 40 diagonally downward toward the rear of the vehicle. A high-voltage cable 60 is connected to the inverter 50. The high-voltage cable 60 is housed inside the cable cover 28 and extends from the inverter 50 toward the rear of the vehicle. In addition, a floor trim 14 is attached between the cable cover 28 and the rear floor panel 13.

[0019] As shown in FIG. 2 , the inverter case 40 is made of metal and includes a housing 41, a lower bracket 42, and an upper bracket 43. The housing 41 has a rectangular box shape with open front and rear ends. An inverter 50, an electrical component, is attached to the bottom surface of the interior of the housing 41. The lower bracket 42 is a leg attached to the underside of the front and rear ends of the housing 41 and extends downward. The lower bracket 42 is attached to the upper surface 12A of the floor tunnel 12 with fastening members such as bolts. The upper bracket 43 is attached to the upper surface of the housing 41. The upper bracket 43 includes a base 44 to which the main body 21 of the console box 20 is fastened and a tongue 46 to which the air straightening plate 30 is fastened. The base 44 has an upwardly convex hat-shaped cross section and a screw hole 45 formed in the web. The tongue 46 is a plate member extending in a crank shape toward the rear of the vehicle from the center of the base 44 in the vehicle width direction. The tongue portion 46 is disposed at the upper rear of the inverter case 40. A bolt hole 47 is formed in the tongue portion 46. A fixing nut 73 (see FIG. 6) is set on the underside of the tongue portion 46.

[0020] The inverter 50 attached to the housing 41 has a connection terminal 51 at its rear end. A connector 61 of a high-voltage cable 60 is connected to the connection terminal 51. The high-voltage cable 60 extends from the rear end of the inverter 50 above the floor tunnel 12 toward the rear of the vehicle.

[0021] As explained above, the console box 20 is made up of the main body 21, the end panel 25, and the cable cover 28. The main body 21 is attached to the upper surface 12A of the floor tunnel 12. The main body 21 is provided with a box portion 22 made of resin for storing small items. The rear end of the box portion 22 is provided with an arm portion 23 extending diagonally downward. The arm portion 23 is provided with a bolt hole 24.

[0022] End panel 25 is a member attached to the upper rear end of main body 21. End panel 25 is made of resin and is provided with air outlets 26 that blow conditioned air rearward. Cable cover 28 is made of resin and is disposed adjacent to main body 21 at the lower rear of main body 21. Cable cover 28 has ribs 28A on its lower surface facing air straightening vane 30 that protrude toward air straightening vane 30 and extend in the vehicle width direction (see FIG. 6).

[0023] As shown in Figures 3 and 4, the air straightening vane 30 includes a plate-shaped portion 31 and a fastening portion 38 that protrudes from the plate-shaped portion 31 toward the front of the vehicle. The plate-shaped portion 31 extends from the fastening portion 38 diagonally downward toward the rear of the vehicle. The plate-shaped portion 31 is divided into 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 slope toward the center in the vehicle width direction as they extend 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 shown in Figure 5, the left and right side end portions 35, 36 include left and right flanges 35A, 36A that extend downward. In addition, the fastening portion 38 is provided with a bolt hole 39.

[0024] As shown in Fig. 4, a plurality of protrusions 32 extending in the vehicle longitudinal direction are provided on the lower surface 31A of the plate-shaped portion 31. As shown in Fig. 5, the protrusions 32 protrude from the lower surface 31A of the plate-shaped portion 31 downward of the vehicle.

[0025] 6, a pin seat 29 is provided on the inner surface of the cable cover 28. The rear part of the rectifying plate 30 is attached to the inner surface of the cable cover 28 by a pin 75.

[0026] Next, the assembly procedure for the console box 20 will be described with reference to Figures 2 and 3. First, as shown in Figure 2, the bolt holes 24 of the arm portions 23 of the main body 21 are aligned with the screw holes 45 provided in the base portion 44 of the inverter case 40. Then, the arm portions 23 are fixed onto the base portion 44 with bolts 71. This attaches the main body 21 to the floor tunnel 12.

[0027] Next, the cable cover 28 is connected to the rear end of the main body 21 and to the top of the floor tunnel 12. This aligns the position of the bolt hole 39 of the fastening portion 38 of the rectifier plate 30 with the position of the bolt hole 47 of the tongue portion 46 of the inverter case 40. A bolt 72 is passed through the bolt holes 47 and 39, and the bolt 72 is screwed into a fixing nut 73 (see Figure 6) to fasten the fastening portion 38 at the front of the rectifier plate 30 to the tongue portion 46. When the fastening portion 38 is fastened to the tongue portion 46, the rectifier plate 30 extends diagonally downward and rearward from the tongue portion 46, which is located at the upper rear of the inverter case 40.

[0028] Next, the front end of the end panel 25 is connected to the rear end of the main body 21 , and the bottom end of the end panel 25 is connected to the top end of the cable cover 28 .

[0029] In this manner, the main body 21 is attached to the upper surface 12A of the floor tunnel 12 via the inverter case 40 disposed therein. Since the inverter 50 is attached inside the inverter case 40, when the main body 21 is attached to the floor tunnel 12, the inverter 50 is housed inside the main body 21. The rectifier plate 30 is housed inside the cable cover 28 and extends from the rear upper part of the inverter case 40 diagonally downward toward the rear of the vehicle. As shown in FIG. 6 , the rib 28A of the cable cover 28 protrudes toward the upper surface of the rectifier plate 30. When the cable cover 28 is attached to the floor tunnel 12, the high-voltage cable 60, the connector 61, and the connection terminal 51 are housed inside the cable cover 28. The rectifier plate 30 covers the high-voltage cable 60, the connector 61, and the connection terminal 51 from above.

[0030] 6, the high-tension cable 60 extends above the floor tunnel 12 toward the rear of the vehicle, and then extends from the rear end of the cable cover 28 toward the rear of the vehicle. The high-tension cable 60 then passes between the floor panel 11 and the floor trim 14 and extends upward from the front surface of the rear floor panel 13 toward the upper surface 13A of the rear floor panel 13. The high-tension cable 60 then extends between the upper surface 13A of the rear floor panel 13 and the rear seat 15 toward the rear of the vehicle.

[0031] Next, the flow of water relative to the vehicle compartment 10 when the electric vehicle 100 is crossing a river will be described with reference to FIGS.

[0032] 6 indicates the water level that has entered the vehicle interior 10 when the vehicle is fording a river. As indicated by the two-dot chain line 91, the water level when the vehicle is fording a river is lower than the inverter 50, and the inverter 50 is not submerged.

[0033] On the other hand, the dashed-dotted line 92 in FIG. 6 indicates the water level when the electric vehicle 100 accelerates while crossing a river. When the electric vehicle 100 accelerates, water is pushed toward the rear of the passenger compartment 10, causing the water level at the rear of the passenger compartment 10 to rise. Furthermore, the force of the water flow increases, causing waves to form on the water surface, as indicated by the curved arrow 93 in FIG. 6. As shown in FIGS. 4 and 5, the lower surface 31A of the plate-shaped portion 31 is provided with a protrusion 32 extending in the fore-and-aft direction of the vehicle. Waves generated on the water surface are rectified by the protrusion 32 and flow toward the rear of the vehicle, as indicated by the arrow 90 in FIG. 4. This prevents waves that strike the lower surface 31A of the plate-shaped portion 31 from flowing backward toward the front of the vehicle. This prevents water from splashing on the inverter 50.

[0034] 4, water that hits the underside 31A of the plate-shaped portion 31 is guided by the flanges 35A, 36A of the left and right side ends 35, 36 and collects in the center in the vehicle width direction. It then flows out from the rear end 37. In this way, water flowing along the underside 31A of the plate-shaped portion 31 is collected in the center behind the plate-shaped portion 31 and flows out from the center toward the rear of the vehicle. This allows the position where rippling occurs in water that has entered the passenger compartment 10 to be located at the rear of the vehicle, away from the inverter 50. This makes it possible to prevent water from splashing on the inverter 50 due to rippling.

[0035] 6, some of the water that flows out from the rear end 37 of the straightening vane 30 may slip between the plate-shaped portion 31 and the cable cover 28 and flow toward the front of the vehicle. This flow of water toward the front of the vehicle is blocked by the rib 28A provided on the cable cover 28, so that the water that has slipped between the plate-shaped portion 31 and the cable cover 28 can be prevented from splashing on the inverter 50.

[0036] As described above, the electric vehicle 100 can prevent water from splashing on the inverter 50 arranged above the floor tunnel 12 when crossing a river.

[0037] In the above description, the electrical component is the inverter 50, but is not limited to this. For example, the electrical component may be a control device such as an ECU, or a battery. [Explanation of symbols]
