Electric compressor

Abstract

An electric compressor includes: a driving part being a driving source configured to generate a rotating force of the electric compressor, the driving part including a stator; a motor housing surrounding the driving part, the motor housing including: one or more first mounting lugs installed on an outer surface of the motor housing; and a press fitting portion formed on an inner surface of the motor housing, the stator of the driving part is press fitted into the press fitting portion; a rear housing surrounding a compressing part configured to rotate due to a rotational driving force generated by the driving part so as to compress a refrigerant; and a center housing installed between the motor housing and the rear housing, wherein the first mounting lugs are installed spaced at a first distance from a center of gravity of the electric compressor overlapping with the press fitting portion.

1 . An electric compressor comprising:
 a driving part being a driving source configured to generate a rotating force of the electric compressor, the driving part comprising a stator;   a motor housing surrounding the driving part, the motor housing comprising:
 one or more first mounting lugs installed on an outer surface of the motor housing; and 
 a press fitting portion formed on an inner surface of the motor housing, the stator of the driving part is press fitted into the press fitting portion; 
   a rear housing surrounding a compressing part configured to rotate due to a rotational driving force generated by the driving part so as to compress a refrigerant; and   a center housing installed between the motor housing and the rear housing,   wherein the first mounting lugs are installed spaced at a first distance from a center of gravity of the electric compressor and overlapping with the press fitting portion.   
     
     
         2 . The electric compressor of  claim 1 , wherein the first mounting lugs of the motor housing are installed as far away as possible from the center of gravity of the electric compressor within the range of the press fitting portion. 
     
     
         3 . The electric compressor of  claim 1 , wherein the first mounting lugs of the motor housing are installed to be spaced at a second distance from each other on the outer surface of the motor housing. 
     
     
         4 . The electric compressor of  claim 3 , wherein the first mounting lugs of the motor housing are symmetrically installed to be collinear with each other on motor housing. 
     
     
         5 . The electric compressor of  claim 1 , wherein the rear housing comprises: one or more second mounting lugs installed on an outer surface of the rear housing, the mounting lugs being installed to be spaced at a third distance from the center of gravity of the electric compressor. 
     
     
         6 . The electric compressor of  claim 5 , wherein the second mounting lugs are installed as far away as possible from the center of gravity of the electric compressor. 
     
     
         7 . The electric compressor of  claim 5 , wherein the mounting lugs of the rear housing are installed to be spaced at a fourth distance from each other on the outer surface of the rear housing. 
     
     
         8 . The electric compressor of  claim 7 , wherein the second mounting lugs of the rear housing are symmetrically installed to be collinear with each other on the rear housing. 
     
     
         9 . The electric compressor of  claim 1 , wherein the first mounting lugs of the motor housing are formed to have a cylindrical shape. 
     
     
         10 . The electric compressor of  claim 5 , wherein the second mounting lugs of the rear housing are formed to have a cylindrical shape.
