1. A scroll compressor, comprising:
a rotating shaft, an end of which is provided with an eccentric structure;
a compression mechanism, comprising a non-orbiting scroll and an orbiting scroll, wherein the orbiting scroll comprises an extending portion which extends from an end plate toward the rotating shaft;
a driving bearing with an axial height L1;
a bushing, wherein the extending portion is coupled with the eccentric structure via the driving bearing and the bushing, so that the rotating shaft is configured to drive the compression mechanism; and
a counterweight arranged on the bushing;
wherein a mass center of the counterweight is located above an axial lower end of the driving bearing, an axial distance from the mass center of the counterweight to an axial center of the driving bearing is L2, and a ratio R of the axial distance L2 to the axial height L1 satisfies: 0.1≤R≤0.4.
