Abstract

A vehicle mounting structure for an electric unit 1 includes a side member 10, a suspension member 5 including a high rigidity portion 5a and a low rigidity portion 5b in a vehicle front-rear direction, and an electric unit 1 in which an inverter 2 and a motor 3 are integrated. The side member 10 includes a curved portion 10c having an upwardly convex curved shape. The curved portion 10c is disposed at a position overlapping with the inverter 2 in the vehicle front-rear direction. The electric unit 1 is fixed to the low rigidity portion 5b.

First claim

The invention claimed is:

1. An assembly for a vehicle, the assembly comprising:
a vehicle mounting structure comprising:
a side member, and
a suspension member configured to extend in a front-rear direction of the vehicle, the suspension member comprising a high rigidity portion having a shape extending obliquely in a rearward and downward direction of the vehicle and a low rigidity portion extending rearward from a rear end of the high rigidity portion,

an electric unit comprising an inverter and a first motor; and
a generator fixed to the side member, wherein a height of a lower-most portion of the generator is less than a height of a lower-most portion of the first motor, wherein;
the side member comprises a curved portion having an upwardly convex curved shape,
a plane perpendicular to the front-rear direction of the vehicle passes through the curved portion and the inverter vehicle front-rear direction, and
the electric unit is fixed to the low rigidity portion.

2. The assembly according to claim 1 , wherein
the inverter is disposed above the side member.

3. The assembly according to claim 1 , wherein
the inverter comprises a high-voltage terminal connection portion and is partially located above the side member, and
a portion of the inverter located above the side member comprises the high-voltage terminal connection portion.

4. The assembly according to claim 1 , wherein
the side member comprises a second high rigidity portion,
the plane is a first plane,
the second high rigidity portion and the first high rigidity portion intersect with a second plane perpendicular to the front-rear direction of the vehicle, and
the generator is fixed to the second high rigidity portion of the side member and has a separate structure from the electric unit.

5. The assembly according to claim 4 , further comprising:
a high-voltage connector connected to the generator, wherein
the high-voltage connector is disposed below the side member.
