Problems solved by technology

[0004] However, on the one hand, the process of opening holes in the slender crankshaft is difficult, and the processing of the lubricating oil passage is complicated; ; In order to meet the strength requirements of the crankshaft, the size and weight of the crankshaft have to be increased, which will lead to an increase in the size and power of the scroll compressor, which is not conducive to the miniaturization of the scroll compressor. Poor economy, especially not suitable for vehicle use

Abstract

The invention discloses a scroll compressor, an air conditioner and a vehicle, and relates to the field of air conditioners. The scroll compressor comprises a machine shell, an upper support, a movable scroll plate, a static scroll plate and a crank shaft, wherein the upper support is fixed on the machine shell; the upper support is provided with an installation cavity, the movable scroll plate and the static scroll plate are installed in the installation cavity, the crank shaft is rotationally arranged on the machine shell and the upper support, the movable scroll plate is meshed with the static scroll plate, the crank shaft drives the movable scroll plate to move; an oil pump is formed between the upper support and the crank shaft, an oil inlet and an oil outlet of the oil pump are formed in the upper support, the oil inlet of the oil pump communicates to the bottom of the shell through an oil suction channel, the oil outlet of the oil pump communicates with the installation cavity through an oil pumping channel, and the oil pumping channel is formed on the upper support. The process difficulty of forming a lubricating oil path on the upper support is low, the structural strengthof the crank shaft cannot be influenced when the lubricating oil path is formed in the upper support, miniaturization of the scroll compressor is facilitated, the operation power of the scroll compressor is reduced, and the economical efficiency of the scroll compressor is improved.

Description

technical field [0001] The invention relates to the field of air conditioning, in particular to a scroll compressor, an air conditioner and a vehicle. Background technique [0002] There are many friction parts in the scroll compressor, such as scroll, bearing, etc. If the friction force of the friction parts is too large, it will have a negative impact on the operation of the scroll compressor. [0003] The relatively mature solution in the prior art is: install an oil pump in the compressor, and open a hole on the crankshaft as a lubricating oil passage, and the oil pump pumps lubricating oil to each friction part through the lubricating oil passage. [0004] However, on the one hand, the process of opening holes in the slender crankshaft is difficult, and the processing of the lubricating oil passage is complicated; ; In order to meet the strength requirements of the crankshaft, the size and weight of the crankshaft have to be increased, which will lead to an increase in...
