  A high voltage control device unit (control device) 20 connected to the power unit 3 via a cable 15 made of a three-phase wire is installed in the passenger compartment 7. FIG. 2 is a schematic sectional side view of the high voltage control device unit 20 as viewed from the rear of the vehicle 1. FIG. 3 is a schematic plan view showing the arrangement configuration of the high-voltage control device unit 20 and the cable 15. FIG. 4 is a schematic partial side view of the vehicle 1 showing the positional relationship between a part of the vehicle body 10 and the cable 15. In each figure, the components (battery module 50, high-voltage device 56, high-voltage distribution component 57, etc.) inside the high-voltage control device unit 20 are simplified.

  As shown in FIG. 2, the high voltage control device unit 20 is installed between the floor panel 9 in the passenger compartment 7 and the driver's seat 5a and the passenger seat 5b. As for the high voltage control equipment unit 20, the whole horizontal direction is installed under the driver's seat 5a and the passenger seat 5b. A projecting center console portion 21 projecting upward is provided at the central portion in the lateral direction. The center console portion 21 is disposed between the driver seat 5a and the passenger seat 5b in the vehicle width direction.

  The high voltage control device unit 20 includes a case 30 including a lower case 31 and an upper cover 41, and a battery module 50 accommodated in the case 30, a high voltage device (control device) 56, and a high voltage distribution component 57. Etc. The case 30 is, for example, a steel plate container. The lower case 31 is a bottomed container type having an opening 32 facing the upper side of the vehicle 1. On the other hand, the upper cover (lid body) 41 is a substantially plate-like member that closes the opening 32 of the lower case 31. The high voltage device 56 and the high voltage distribution component 57 are arranged in the center console unit 21. The high-voltage device 56 and the high-voltage power distribution component 57 are covered with a reinforcing member 59 having a substantially trapezoidal cross section when viewed from the front-rear direction. The lower case 31 is in the shape of a bottomed container, and the inside thereof is an accommodating portion 31c for accommodating the battery module 50 and the like.

  Although detailed illustration is omitted, the battery module 50 is installed in a state where a large number of battery cells are bundled together. The high voltage device 56 is an electronic device in which an inverter, a DC / DC converter (DC converter), an ECU, and the like are integrally configured, although the detailed internal configuration is not shown. The function of the high voltage device 56 obtains a direct current from the battery module 50, converts the direct current into a three-phase alternating current, supplies the current to the motor 3b to drive it, and regenerates the current from the motor 3b. Is converted into a direct current, so that the battery module 50 can be charged.

  A shift lever (select lever) 60, which is a shift operation device according to the present invention, is mounted on the upper portion (directly above position) of the high-voltage control device unit 20. The shift lever 60 is a device that is installed on the case 30 of the high-voltage control device unit 20 and outputs the travel range position selected by the driver. That is, the shift lever 60 is an operation means that is operated by the driver to select a parking position, a neutral position, a traveling position, and the like as the shift position of the vehicle 1. What is performed by the shift lever 60 is selection of shift positions of at least P, D, N, and R. The shift lever 60 is an electric communication type (shift-by-wire type) shift operation device, and although not shown, a signal line for outputting the travel range position is connected to a harness in the passenger compartment 7. Thus, in this embodiment, since the shift lever 60 mounted on the vehicle 1 is a shift-by-wire shift operation device, a shift wire for output of the travel range position connected to the shift lever 60 is not necessary.

  The vehicle 1 of the present embodiment includes a first shift lever 60-1 configured so that the output of the travel range position is transmitted via an electrical signal as the shift lever 60, and the output of the travel range position is the shift wire 65. A vehicle body 10 having a structure capable of selectively mounting either a second shift lever 60-2 (see FIG. 7 of the third embodiment described later) configured to be transmitted by the mechanical operation of Vehicle. Specifically, as shown in FIG. 3 and FIG. 4, a through hole 13 is provided in the dashboard portion 12 that separates the engine room 2 and the vehicle compartment 7. When the second shift lever 60-2 is mounted, the through hole 13 is used to pass the shift wire 65 for connecting the power unit 3 in the engine room 2 and the shift lever 60.

  In the present embodiment, the first shift lever 60 (of the shift-by-wire system) configured to transmit the output of the travel range position via an electrical signal is mounted. Since the first shift lever 60 does not require the shift wire 65, when the second shift lever 60 is mounted, the through hole 13 in which the shift wire 65 is disposed and the path leading to the through hole 13 become a dead space. Therefore, instead of the shift wire 65, the high-voltage cable 15 formed by connecting the motor 3b in the engine room 2 and the high-voltage control device unit 20 in the passenger compartment 7 is passed through the through-hole 13, The cable 15 is introduced from the engine room 2 into the vehicle compartment 7. That is, the cable 15 for connecting the motor 3b and the high voltage control device unit 20 is disposed in the through hole 13 for disposing the shift wire 65. Thereby, the cable 15 is arrange | positioned using the dead space in the vehicle 1 effectively.

  In addition, since the cable 15 that connects the motor 3b and the high voltage control device unit 20 is provided using the through hole 13 for the shift wire 65, it is not necessary to provide a dedicated path for the cable 15. . Thereby, while being able to aim at the effective utilization of the space in the compartment 7, the weight reduction and cost reduction of the vehicle 1 can be achieved.

  Further, as shown in FIG. 3, the through hole 13 for the shift wire 65 is provided at a substantially central portion of the dashboard portion 12 in the vehicle width direction, and is disposed in the vehicle compartment 7 through the through hole 13. The cable 15 thus extended extends in the front-rear direction between the feet of the driver seat 5a and the passenger seat 5b, and is connected to the high voltage control device unit 20 of the center console section 21. In addition, since the actual cable 15 is arrange | positioned under the floor board in the step of the driver's seat 5a and the passenger seat 5b, it is not exposed in the state seen from upper direction.

  Thus, by arranging the high voltage control device unit 20 in the center console portion 21, the high voltage control device unit 20 is arranged by effectively using the dead space in the passenger compartment 7. Further, since a high voltage is applied to the cable 15 connecting the motor 3b and the high voltage control device unit 20, the route through which the cable 15 passes through the passenger compartment 7 is seated in the driver's seat 5a and the passenger seat 5b. By setting the position away from the occupant, it is necessary to make it difficult for the occupant to be affected by the high voltage. In this regard, according to the arrangement configuration of the present embodiment, the shift lever 60 and the high voltage control device unit 20 are arranged in the center console portion 21 between the driver seat 5a and the passenger seat 5b, so that the motor in the engine room 2 is provided. The cable 15 extending from 3b to the shift lever 60 in the passenger compartment 7 can be arranged on a straight line extending in the front-rear direction at the center in the width direction of the vehicle 1. Therefore, the cable 15 can be disposed in a safe position that does not affect the passengers in the passenger compartment 7 in a space-saving manner, and can be disposed at a low cost with a simple configuration.

  Further, since the high-voltage control device unit 20 is disposed between the driver's seat 5a and the passenger seat 5b, a high outside dimension is provided below the center console portion 21 that is a dead space in the passenger compartment 7. The voltage control device unit 20 is efficiently arranged. Further, since the shift lever 60 is disposed directly above the high voltage control device unit 20, the shift lever 60 is disposed at a position where it can be easily operated from the driver's seat 5a.

  The shift lever 60 is directly placed on the case 30 of the high voltage control device unit 20. Thereby, since the shift lever 60 can be mounted (supported) using the case 30 of the high-voltage control device unit 20, a dedicated component for mounting the shift lever 60 becomes unnecessary. Therefore, it is possible to reduce the number of parts and simplify the vehicle assembly process.

  As shown in FIGS. 3 and 4, the cable 15 of the present embodiment is covered with a corrugated tube 15 a and is a flexible wire that can be bent and deformed. On the other hand, a rigid cylindrical member 15b made of a stainless steel pipe, a resin cable holder, or the like is attached to a part of the cable 15. The portion to which the cylindrical member 15b is attached is a hard portion that does not bend and deform. Therefore, the cable 15 is a portion having a part thereof having flexibility and the other part being a portion having no flexibility.

  As described above, since a part of the cable 15 is a flexible part, the degree of freedom in arrangement is improved in the cable arrangement process described later, so that the cable 15 can be easily arranged in a desired path. become. Further, since a part of the cable 15 is covered with the rigid cylindrical member 15b, the operator can hold the part and assemble it when the cable 15 is assembled (at the time of installation). As a result, the operator can easily and quickly carry out the operation of holding the cable 15 by hand from the motor 3b in the engine room 2 to the high voltage control device unit 20 in the vehicle compartment 7. Further, the portion of the cable 15 covered with the cylindrical member 15b is prevented from being worn by rubbing against other parts and members after the arrangement.

  Next, a process of assembling the power unit 3 and the cable 15 to the vehicle body 10 in the assembly of the vehicle 1 of the present embodiment will be described. FIG. 5 is a schematic partial side view for explaining the assembly process of the vehicle 1. As shown in the figure, in this process, the power unit 3 is inserted into the engine room 2 from the lower side of the vehicle 1 and installed, and the cable 15 connected to the power unit 3 (motor 3b) is connected to the dashboard section 12. The cable 15 is introduced into the vehicle compartment 7 by being inserted into the through-holes 13, and the tip of the cable 15 introduced into the vehicle compartment 7 is installed in the vehicle compartment 7 in advance. The process of connecting to is performed in this order.

  In this case, the process of introducing the cable 15 connected to the power unit 3 into the vehicle compartment 7 through the through hole 13 is the same as the process of inserting the power unit 3 into the engine room 2 from the lower side of the vehicle 1 and installing it. It is also possible to carry out in a process.

  In the present embodiment, the through hole 13 for the shift wire 65 provided in the dashboard portion 12 of the vehicle body 10 is configured to be used for arranging the cable 15 for the high voltage control device unit 20. Accordingly, the cable 15 can be disposed (assembled) in the same process as the process of mounting the power unit 3 in the engine room 2, so that a dedicated process for disposing the cable 15 can be omitted.

[Second Embodiment]
Next, a second embodiment of the present invention will be described. In the description of the second embodiment and the corresponding drawings, the same or corresponding components as those in the first embodiment are denoted by the same reference numerals, and detailed description thereof will be omitted below. In addition, matters other than those described below are the same as those in the first embodiment. This is the same in other embodiments.

  FIG. 6 is a diagram showing a cable arrangement structure according to the second embodiment of the present invention, and is a schematic partial side view of the vehicle 1 showing an arrangement relationship between a part of the vehicle body 10 and the cables 15 and the like. In the first embodiment, the wiring connected to the shift lever 60 is connected to a harness (not shown) in the passenger compartment 7 without passing through the through hole 13, whereas in the present embodiment, the wiring is connected to the shift lever 60. The wiring 62 is connected to the power unit 3 in the engine room 2 through the through hole 13 together with the cable 15. In the present embodiment, although not shown, the power unit 3 includes a speed change mechanism for performing a speed change operation according to the operation signal of the shift lever 60 transmitted via the wiring 62.

  That is, in this embodiment, the cable 15 that connects the motor 3b and the high-voltage control device unit 20 and the wiring 62 that is connected to the shift lever 60 both pass through the through hole 13 of the dashboard portion 12. Thus, the cable 15 and the wiring 62 are arranged with a part of their paths in common.

  A process of assembling the power unit 3 and the cable 15 to the vehicle body 10 will be described. In this process, the dashboard unit is formed in a state where the power unit 3 is inserted into the engine room 2 from the lower side of the vehicle 1 and installed, and a part of the cable 15 and the wiring 62 connected to the power unit 3 are integrated together. The cable 15 and the wiring 62 are introduced into the vehicle compartment 7 by being inserted into the through-holes 13 of the twelve, and the tip of the cable 15 introduced into the vehicle compartment 7 is connected to the high voltage control device unit 20 and wired.
