ELECTRIC COMPRESSOR FOR VEHICLE AIR CONDITIONER

摘要

An electric compressor to be mounted on an engine in an engine compartment of a vehicle includes a compression mechanism, an electric motor, a motor driving circuit, a housing, a first mounting leg and a second mounting leg. The housing accommodates therein the compression mechanism, the electric motor and the motor driving circuit. The first mounting leg projects from the housing at a position adjacent to the compression mechanism. The second mounting leg projects from the housing at a position adjacent to the motor driving circuit. Each of the first mounting leg and the second mounting leg includes a fastening portion to be fastened to a portion of the engine and a connecting portion that connects the fastening portion with the housing. The connecting portion of the first mounting leg is made to be broken more easily than connecting portion of the second mounting leg.

主权项

1. An electric compressor configured to be mounted on an engine in an engine compartment of a vehicle, comprising:
a compression mechanism for compressing refrigerant; an electric motor for driving the compression mechanism; a motor driving circuit for driving the electric motor; a housing accommodating therein the compression mechanism, the electric motor and the motor driving circuit; a first mounting leg projecting from the housing at a position that is close to the compression mechanism; and a second mounting leg projecting from the housing at a position that is close to the motor driving circuit, wherein each of the first mounting leg and the second mounting leg includes a fastening portion configured to be fastened to the engine and a connecting portion which connects the fastening portion with the housing; wherein the connecting portion of the first mounting leg is configured to be broken more easily than the connecting portion of the second mounting leg so that the connecting portion of the first mounting leg that is closed to the compression mechanism suppresses the transmission of the external force to the connecting portion of the second mounting leg when external force applied to the vehicle is transmitted to the housing.
