It can be disposed between the seat 5-1 and the passenger seat 5-2. Therefore, it is possible to optimize each temperature environment while arranging the battery module 50, the high voltage device 56, and the power distribution component 57 adjacent to each other.

  In addition, the power distribution component 57 is a component having a complicated structure in which a large number of wiring branches and a high voltage is applied. Therefore, in order to ensure safety and maintain the function of the vehicle, it is necessary to protect it from an impact at the time of a side collision of the vehicle. Therefore, the power distribution component 57 is disposed together with the main switch 58 in the center console portion 21 that is located farthest from both side surfaces of the vehicle 1.

  Further, at the time of a side collision of the vehicle 1, an excessive collision load is applied to the driver seat 5-1 or the passenger seat 5-2 disposed at a position outside the high voltage control device unit 20 in the vehicle width direction. Thus, the driver seat 5-1 or the passenger seat 5-2 may be deformed or collapsed. On the other hand, in the present embodiment, the battery 50 and the main switch 58 are disposed below the seat rails 18 and 19, so that the driver seat 5-1 or the passenger seat 5-2 is deformed and collapsed. It is possible to suppress the probability that the influence of the above will affect the battery 50 and the main switch 58.

  Further, as shown in FIG. 4, a reinforcing member 59 surrounding both sides of the high voltage device 56 and the power distribution component 57 in the vehicle width direction is provided, and the reinforcing member 59 is provided with the high voltage device 56 and the power distribution component 57 and the driver's seat. 5-1 and the passenger seat 5-2.

Therefore, it is possible to prevent the high voltage device 56 and the power distribution component 57 from being crushed at the time of a side collision of the vehicle 1.

  As shown in FIG. 5, the inverter device 56a and the converter device 56b of the high-voltage device 56 are disposed between the driver seat 5-1 and the passenger seat 5-2 in the vehicle width direction.

  Since the inverter device 56a having an inverter and the converter device 56b having a DC-DC converter are relatively large parts, the high-voltage device 56 including them is relatively easy to secure a space. It is desirable to arrange between the driver seat 5-1 and the passenger seat 5-2. Thereby, it is possible to efficiently mount the inverter device 56a and the converter device 56b having relatively large outer dimensions by effectively using the space in the passenger compartment 7.

  Further, as shown in FIGS. 3 to 5, the inverter device 56 a and the converter device 56 b of the high-voltage device 56 are in a back-to-back state in the vehicle width direction of the vehicle 1 (the surfaces on the center side in the vehicle width direction are butted together. Installed). Thereby, it is possible to save the space of the high voltage device 56 including the inverter device 56a and the converter device 56b whose outer dimensions are relatively large.

  Further, since the inverter device 56a and the converter device 56b arranged between the seats 5-1 and 5-2 are installed in a back-to-back state, a detailed illustration is omitted, but a cooling duct or the like for cooling them is used for cooling. When this structure is provided, the cooling structure can be shared. Therefore, it is possible to reduce the number of parts and save space. In addition, since the wires extending from the inverter device 56a and the converter device 56b can be drawn out from the lower surface side, the length of the wire connected from the battery module 50 to the inverter device 56a and the converter device 56b can be kept short. It becomes. In other words, since the high-voltage wiring requires a countermeasure against electric leakage and high-voltage protection over the entire length of the wiring path, it is desirable to make the wiring path as short as possible. Thus, an efficient arrangement is possible in which the path length of the wiring connected to the high voltage device 56 is kept short.

  Further, in the mounting structure of the present embodiment, as shown in FIG. 3, a cross member 11 that is a pair of reinforcing members disposed on the floor panel 9 at a predetermined interval in the front-rear direction of the vehicle 1 and extending in the vehicle width direction. , 12 and side frames 26, 27, which are another pair of reinforcing members that are arranged at predetermined intervals in the vehicle width direction of the vehicle 1 and extend in the front-rear direction. The high-voltage control device unit 20 is arranged at a position where the front-rear direction and the vehicle width direction are surrounded by the cross members 11, 12 and the side frames 26, 27.

  As described above, since the four sides of the high voltage control device unit 20 are surrounded by the cross members 11 and 12 and the side frames 26 and 27, the high voltage control device unit 20 is crushed by an impact when the vehicle 1 collides. It can be effectively prevented.

  Further, as shown in FIG. 2, the high voltage control device unit 20 includes a battery case 30 that integrally includes a battery module 50, a high voltage device 56, a power distribution component 57, and a main switch 58, and the battery case 30. And a frame member 55 that supports the battery module 50 in the battery case 30. With this configuration, it is possible to effectively protect the battery module 50 for driving the vehicle, the high voltage device 56 attached thereto, the power distribution component 57, the main switch 58, and the like from the impact at the time of the collision of the vehicle 1. In addition, it is possible to manage the environmental temperature of the battery module 50 to an appropriate temperature with the heat insulating material 60 installed in the battery case 30.

  As described above, according to the high voltage control device unit 20 of the present embodiment, the battery module 50 having a relatively low management temperature is disposed below the seat rails 18 and 19 in the passenger compartment 7 so that the management temperature is low. By arranging the relatively high high voltage device 56 (inverter device 56a, converter device 56b) between the left and right seats 5-1 and 5-2, the battery module 50 and the high voltage device 56 are arranged adjacent to each other, It is possible to place them in an appropriate temperature environment.

  That is, in the vehicle 1 provided with the battery module 50 for driving the vehicle, the battery module 50 and its control device are laid out in the passenger compartment 7, thereby reducing the front noise and reducing the size of the vehicle 1. In this case, the above-described mounting structure is adopted to optimize the arrangement of the battery module 50, the high voltage device 56, and the like.
