  • Patent number: 11407285
    Abstract: A vehicle cooling mechanism includes a first radiator configured to cool a battery of a vehicle, a second radiator configured to cool a power conversion device that converts electric power supplied from the battery and electric power supplied to the battery, and an air guide duct portion configured to guide outside air from an opening portion provided in a front end portion of the vehicle to the first radiator and the second radiator. The first radiator is arranged above the second radiator. At least a part of the second radiator is arranged so as to overlap the opening portion as viewed from a front side of the vehicle. An upper end portion of the second radiator is positioned above an upper end portion of the opening portion. A lower end portion of the second radiator is positioned below the upper end portion of the opening portion.

  • Patent number: 10787083
    Abstract: A vehicle includes an electric motor, a storage battery which supplies power to the electric motor, and a power line which configures a power transmission path between the electric motor and the storage battery. The power line is arranged to extend in a front-rear direction of the vehicle along a bottom surface of the vehicle. A part of the power line is covered by a protection member from below with a gap between the power line and the bottom surface. A fixing point of the protection member to the bottom surface is positioned on a front side of the protection member and on an outer side of the protection member in a vehicle width direction.
