[0005] [Patent Document 1] Japanese Unexamined Patent Application Publication No. 2010 - 18085 Summary of the Invention

[0006] [Problems to be Solved by the Invention]

[0007] However, in recent years, there has been a battery electric vehicle (hereinafter referred to as BEV) that travels by driving an electric motor using electric power from a battery charged by an external power source. In such a BEV, a high - voltage cable connecting the battery to a high - voltage device is sometimes arranged in the passenger compartment. In this case, when the passenger compartment is impacted due to a collision or the like, it is required that the high - voltage cable does not protrude into the passenger compartment.

[0008] Therefore, an object of the present disclosure is to suppress the high - voltage cable from protruding into the passenger compartment during a collision in an electric vehicle in which the high - voltage cable is arranged in the passenger compartment.

[0009] [Means for Solving the Problems]

[0010] The electric vehicle according to the present disclosure includes: a high - voltage cable arranged in the passenger compartment; a center console box for housing the high - voltage cable; a center console box bracket connecting the center console box to the upper surface of the floor tunnel; and a metal cover arranged inside the center console box and covering the upper part of the high - voltage cable. The electric vehicle is characterized in that the metal cover is rotatably mounted relative to the center console box bracket.

[0011] In this way, since the high - voltage cable is covered by the metal cover, external force can be not applied to the high - voltage cable. In addition, when the passenger compartment receives a large impact due to a collision, the metal cover rotates relative to the center console box bracket, so that a large impact force applied to the metal cover is suppressed, and the breakage of the metal cover is suppressed. Thereby, the situation where the metal cover breaks and the high - voltage cable protrudes into the passenger compartment during a collision can be suppressed.

[0012] In the electric vehicle of the present disclosure, it is also possible that the center control box includes: a main body installed on the upper surface of the floor tunnel via the center control box bracket disposed inside; and a cable cover disposed adjacent to the rear of the main body and accommodating the high-voltage cable inside. The center control box bracket is box-shaped and accommodates an inverter inside. The high-voltage cable is connected to the rear end of the inverter and extends rearward of the vehicle from the rear end of the inverter above the floor tunnel. The metal cover is disposed inside the cable cover and covers the upper part of the connection portion between the inverter and the high-voltage cable and the upper part of the high-voltage cable.

[0013] In this way, since the upper part of the connection portion between the inverter and the high-voltage cable and the upper part of the high-voltage cable are covered by the metal cover, external force can be prevented from being applied to the connection portion between the inverter and the high-voltage cable and the high-voltage cable. In addition, it is possible to suppress the connection portion between the inverter and the high-voltage cable and the high-voltage cable from being exposed into the passenger compartment during a collision.

[0014] In the electric vehicle of the present disclosure, the metal cover and the center control box bracket may also be fastened by one bolt.

[0015] As a result, the occupant cannot remove the metal cover without using tools, so that it is possible to suppress the occupant from accidentally touching the connection portion between the inverter and the high-voltage cable and the high-voltage cable.

[0016] [Advantages of the Invention]

[0017] In the electric vehicle of the present disclosure where the high-voltage cable is disposed in the passenger compartment, it is possible to suppress the high-voltage cable from being exposed into the passenger compartment during a collision. [Brief Description of the Drawings]

[0023] Hereinafter, the electric vehicle 100 according to the embodiment will be described with reference to the drawings. The electric vehicle 100 is described as a BEV, but it may also be a hybrid vehicle that travels by an engine and an electric motor. As Figure 1 shown, the electric vehicle 100 includes a vehicle cabin 10, a center console box 20, a center console box bracket 40, an inverter 50, a metal cover 30, and a high-voltage cable 60. In addition, FR, UP, and RH shown in each figure respectively represent the front side, the upper side, and the right side of the electric vehicle 100. In addition, the opposite directions of FR, UP, and RH represent the rear side, the lower side, and the left side. Hereinafter, when only the directions of front and rear, left and right, and up and down are used for description, unless otherwise specified, the front and rear in the front-rear direction of the electric vehicle 100, the left and right in the left-right direction, and the up and down in the up-down direction are meant.

[0024] The vehicle cabin 10 includes a floor 11, a floor tunnel 12, and a rear floor 13. The floor 11 is a plate member that forms the ground of the vehicle cabin 10. The floor tunnel 12 is a portion that is disposed at the center in the vehicle width direction of the vehicle cabin 10 and protrudes upward from the upper surface 11A of the floor 11. The floor tunnel 12 has a trough-shaped cross section that is open at the bottom and extends from the front bulkhead (not shown) at the front of the vehicle cabin toward the rear of the vehicle to the front of the rear floor 13. The rear floor 13 is a pedestal-shaped portion that stands upward from the floor 11 behind the floor tunnel 12. Left and right front seats (not shown) are installed above the floor 11 on both sides of the floor tunnel 12. In addition, a rear seat 15 is installed above the rear floor 13. The regions above the upper surface 11A of the floor 11, the regions above the upper surface 12A of the floor tunnel 12, and the regions above the upper surface 13A of the rear floor 13 constitute the region inside the vehicle cabin.

[0025] The center console box 20 is installed on the floor tunnel 12. The center console box 20 is an interior component that houses small items inside. The center console box 20 includes a main body 21, end plates 25, and a cable cover 28. As will be described later, the main body 21 is installed on the upper surface 12A of the floor tunnel 12 via the center console box bracket 40 disposed inside. The inverter 50 is installed inside the center console box bracket 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 installed between the cable cover 28 and the rear floor 13.

[0026] As Figure 2As shown, the center control box bracket 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. An inverter 50 is installed on the bottom surface inside the housing portion 41. The lower bracket 42 is a leg portion that is installed on the lower surfaces of the front end and the rear end of the housing portion 41 and extends downward. The lower bracket 42 is installed on the upper surface 12A of the floor channel 12 by fastening members 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 center control box 20 and a tongue portion 46 for fastening the metal cover 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 at the center portion in the vehicle width direction of the pedestal portion 44. A bolt hole 47 is provided in the tongue portion 46. In addition, a fixing nut 73 (refer to Figure 4 ) is set on the lower surface of the tongue portion 46 (refer to Figure 4 ).

[0027] The inverter 50 installed on 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 from the rear end of the inverter 50 above the floor channel 12 toward the rear of the vehicle. In this way, the high-voltage cable 60 is arranged inside the vehicle compartment. Here, the connection terminal 51 and the connector 61 constitute a connection portion between the inverter 50 and the high-voltage cable 60.

[0028] As described before, the center control 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 includes a box portion 22 made of resin for accommodating 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.

[0029] 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-conditioned air toward the rear. The cable cover 28 is made of resin and is arranged adjacent to the main body 21 at the lower part behind the main body 21.

[0030] The metal cover 30 includes a plate-shaped portion 31 and a fastening portion 32 that protrudes forward from the plate-shaped portion 31. A bolt hole 33 is provided in the fastening portion 32. As Figure 4 shown, the metal cover 30 is installed on the inner surface of the cable cover 28. A pin seat 29 is provided on the inner surface of the cable cover 28. The metal cover 30 is installed on the inner surface of the cable cover 28 by a pin 75.

[0031] Next, with reference to Figure 2 , Figure 3 the assembly steps of the center control box 20 will be described. First, as Figure 2As 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 center control box bracket 40. Then, fix the arm portion 23 to the pedestal portion 44 using a bolt 71. Thus, the center control box bracket 40 connects the main body 21 and the upper surface 12A of the floor tunnel 12.

[0032] Next, connect the cable cover 28 to the rear end of the main body 21 and above the floor tunnel 12. Thus, the position of the bolt hole 33 of the fastening portion 32 of the metal cover 30 coincides with the position of the bolt hole 47 of the tongue portion 46 of the center control box bracket 40. Pass a bolt 72 through the bolt holes 47 and 33, and screw the bolt 72 into the fixing nut 73 (refer to Figure 4 ) to fasten the fastening portion 32 to the tongue portion 46.

[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 installed on the upper surface 12A of the floor tunnel 12 via the center control box bracket 40 disposed inside. And, since the inverter 50 is installed inside the center control box bracket 40, when the main body 21 is installed on the floor tunnel 12, the inverter 50 is housed inside the main body 21. In addition, as Figure 4 shown, when the cable cover 28 is installed above the floor tunnel 12, the high-voltage cable 60, the connector 61, and the connection terminal 51 are housed in the cable cover 28. In addition, the metal cover 30 covers the high-voltage cable 60, the connector 61, and the connection terminal 51 from above. Therefore, the metal cover 30 covers the high-voltage cable 60 and the connection portion between the inverter 50 and the high-voltage cable 60 from above. In addition, since the metal cover 30 is fastened to the center control box bracket 40 by one bolt 72, the metal cover 30 can rotate around the periphery of the bolt 72 when a large force is applied. In addition, the tightening torque of the bolt 72 can also be managed so that the metal cover 30 can rotate when a large force is applied.

[0035] As Figure 4 shown, the high-voltage cable 60 extends rearward of the vehicle above the floor tunnel 12 and extends rearward of the vehicle from the rear end of the cable cover 28. Moreover, the high-voltage cable 60 passes between the floor 11 and the floor trim 14 and extends upward from the front surface of the rear floor 13 to the upper surface 13A of the rear floor 13. And, it extends rearward of the vehicle between the upper surface 13A of the rear floor 13 and the rear seat 15.

[0036] Next, refer to Figure 5 to describe the movement and deformation of each part during a side collision of the electric vehicle 100. As Figure 5As shown by the hollow arrow 91 in the figure, when an impact force is input from the left side of the vehicle due to a side collision, the floor tunnel 12 deforms or moves to the right. As a result, the center console bracket 40 moves or deforms to the right direction. At this time, the fastening portion 32 of the metal cover 30 moves to the right direction together with the center console bracket 40. The fastening portion 32 is fastened to the tongue portion 46 by a bolt 72. Therefore, when the fastening portion 32 receives a large impact force, as Figure 5 shown by the hollow arrow 92 in the figure, it rotates around the periphery of the bolt 72. Thereby, it is possible to suppress a large impact force being applied to the metal cover 30 and suppress the metal cover 30 from breaking. And thereby, it is possible to suppress the high-voltage cable 60 disposed in the passenger compartment from being exposed into the passenger compartment when the metal cover 30 breaks during a side collision.

[0037] As described above, the electric vehicle 100 uses the metal cover 30 to cover the high-voltage cable 60 disposed in the passenger compartment, so that an external force can be prevented from being applied to the high-voltage cable 60. In addition, during a collision, by rotating the metal cover 30 relative to the center console bracket 40 to avoid the impact force, it is possible to suppress the metal cover 30 from breaking and suppress the high-voltage cable 60 from being exposed into the passenger compartment.

[0038] In addition, the electric vehicle 100 uses the metal cover 30 to cover above the connection portion of the inverter 50 and the high-voltage cable 60 and above the high-voltage cable 60, so that an external force can be prevented from being applied to the connection portion of the inverter 50 and the high-voltage cable 60 and the high-voltage cable 60. In addition, it is possible to suppress the connection portion of the converter 50 and the high-voltage cable 60 and the high-voltage cable 60 from being exposed into the passenger compartment during a collision.

[0039] In addition, in the electric vehicle 100, the cable cover 28, the floor trim 14 and the rear seat 15 cover above the high-voltage cable 60, so that it is possible to suppress the high-voltage cable 60 disposed in the passenger compartment from being exposed into the passenger compartment.

[0040] Moreover, in the electric vehicle 100, the metal cover 30 and the center console bracket 40 are fastened by bolts 72, so that the occupant cannot remove the metal cover 30 without using tools. Therefore, it is possible to suppress the occupant from accidentally touching the connection portion of the inverter 50 and the high-voltage cable 60 and the high-voltage cable 60 disposed in the passenger compartment.
