Abstract

A protection structure of a power control unit capable of realizing low cost and light weight, and protecting the power control unit is provided. Therefore, a protective holding rack (91) and an installing part (94) of a front supporting frame (34) are in a left-side-offset arrangement relative to a central part in a vehicle width direction of a PCU (5), and further, the installing part (94) is disposed between a fixed point of a left side vehicle rack (16b) and a foot part (41), namely a vehicle body side fixed part (95), and a fixed point of the front supporting frame (34) and the PCU (5), namely an installing sheet (84).

Description

technical field [0001] The invention relates to a protection structure of a power control unit. Background technique [0002] Conventionally, in electric vehicles and the like, for example, an electric motor is accommodated in a motor compartment disposed at the front of the vehicle body, a power control unit (hereinafter referred to as PCU) that controls the driving of the electric motor is disposed above the electric motor, and a power control unit (hereinafter referred to as PCU) is arranged between the electric motor and the PCU. The front mounted radiator. [0003] In such a vehicle, for example, in a frontal collision (hereinafter referred to as a frontal collision), peripheral components such as a radiator are pressed into the PCU by an impact load input from the front of the vehicle body. [0004] On the other hand, for example, Patent Document 1 discloses a configuration in which a cooling mechanism is provided below the electronic component unit, and the front end...
