Electrified vehicle
A case in which a terminal block having a main body to which an electric motor is connected at one end side and a bus bar to which a power control device is connected at the other end side is integrally fixed is installed has an opening that matches the shape of the main body, and a hole into which the main body is fitted is formed. As a result, the terminal block is positioned by fitting the main body into a hole formed in the case and having an opening that matches the shape of the main body of the terminal block. By positioning with the main body integrated with the bus bar, it is possible to reduce the relative positional deviation amount between the bus bar and the electric motor or the power control device. Therefore, it is possible to improve the positioning accuracy of the terminal block.
1 . An electrified vehicle comprising:
an electric motor;
a power control device configured to control the electric motor;
a terminal block that includes
a bus bar to which the electric motor is connected on a first end and the power control device is connected on a second end and
a main body to which the bus bar is integrally fixed; and
a case in which the terminal block is installed, wherein
the case includes an opening portion,
a shape of the opening portion matches an outer peripheral shape of the main body, and
the terminal block is configured to be fitted into the opening portion such that an inner peripheral surface of the opening portion contacts an outer peripheral surface of the main body.
2 . The electrified vehicle according to claim 1 , wherein the terminal block includes a plurality of the bas bars, and
the bus bars are arranged parallel to each other.
3 . The electrified vehicle according to claim 1 , wherein the bus bar includes a longitudinally shaped portion which extends from the main body toward the second end and to which the power control device is connected at a distal end portion on the second end.
4 . The electrified vehicle according to claim 3 , further comprising a power transmission device to which the electric motor is coupled to transmit power, wherein:
the case houses, as an electromechanical integration unit, a drive device and the power control device, the drive device including the electric motor and the power transmission device;
the power control device is disposed adjacently above the electric motor in a vertical direction when mounted on the electrified vehicle; and
the longitudinally shaped portion of the bus bar extends upward from the main body in the vertical direction when mounted on the electrified vehicle.
5 . The electrified vehicle according to claim 4 , wherein:
the electric motor includes a first electric motor and a second electric motor;
the drive device is arranged such that, when mounted on the electrified vehicle, a rotational axis of the first electric motor, a rotational axis of the second electric motor, and a rotational axis of the power transmission device are each parallel to a horizontal direction perpendicular to a longitudinal direction of the electrified vehicle, and the rotational axis of the second electric motor is located above the rotational axis of the first electric motor in the vertical direction;
the power control device is arranged such that, when mounted on the electrified vehicle, a lower portion of the power control device overlaps an upper portion of the second electric motor when viewed in the longitudinal direction, and the lower portion of the power control device is located above the first electric motor in the vertical direction; and
the terminal block is installed in the longitudinal direction with respect to the second electric motor, and installed above the first electric motor in the vertical direction, when mounted on the electrified vehicle.
6 . The electrified vehicle according to claim 5 , wherein the distal end portion of the bus bar on the second end is connected to a power control device side bus bar that extends downward in the vertical direction from an upper portion of the power control device in the vertical direction when mounted on the electrified vehicle.
