Electric vehicle

Abstract

The invention provides an electric vehicle, which, on the basis of realizing low cost and light weight, can inhibit interference of a power control unit or a PCU mounting frame and other parts disposed in a motor chamber, thereby protecting the power control unit. The PCU mounting frame (22) surrounds a PCU (5) from the periphery, and the PCU mounting frame (22) is provided with a front part supporting leg part (32) connecting a front supporting frame (25) and a left side supporting frame (24), a back part supporting leg part (34) connecting the left side supporting frame (24) and a back supporting frame, the back part supporting leg part (34) is in an offset configuration to an internal side along a left-right direction relative to the front part supporting leg part (32) in a mode of getting away from a travel simulator (6) in a left-right direction, and is at the back part of a front end part of the travel simulator (6).

Description

Technical field [0001] The present invention relates to electric vehicles. Background technique [0002] Conventionally, in an electric vehicle or the like, an electric motor is housed in a motor room arranged in the front part of the vehicle body, and a power control unit (hereinafter referred to as PCU) arranged above the electric motor to control the driving of the electric motor, for example. [0003] As such a PCU, for example, Patent Document 1 discloses a structure in which a plurality of electrical devices such as a DC-DC converter and an inverter are collectively housed in a housing. According to this structure, it is possible to reduce the number of cables to connect each electric device, and therefore it is considered that cost reduction and space efficiency improvement can be achieved. [0004] On the other hand, the PCU described in Patent Document 1 described above has a relatively large size due to the fact that a plurality of electric devices are housed in a housing....

AI Technical Summary

Problems solved by technology

[0011] However, as mentioned above, the PCU is a relatively large device, so if the PCU and the stroke simulator are housed integrally in the motor room, there is a problem that the layout of the motor room will be reduced.

In addition, when such a structure is adopted, for example, in a frontal collision (hereinafter referred to as a frontal collision), the stroke simulator, the PCU, and the frame supporting the PCU are opposed to each other by an impact load input from the front of the vehicle body. Interference occurs due to ground displacement, and the PCU may be damaged

[0012] On the other hand, it is conceivable to increase the rigidity or strength of the PCU case itself or the frame supporting the case, but there are problems of high manufacturing cost and increased weight.
