Description

Technical Field

[0001] The utility model relates to the technical field of compressor rocker plates, in particular to a rocker plate structure for an automobile air-conditioning compressor. Background Art

[0002] The compressor is the heart of the refrigeration system. It sucks in low-temperature and low-pressure refrigerant gas from the intake pipe, compresses it by driving the piston through the operation of the motor, and then discharges high-temperature and high-pressure refrigerant gas to the exhaust pipe, providing power for the refrigeration cycle, thereby realizing the refrigeration cycle of compression → condensation → expansion → evaporation. The compressor currently widely used in automobiles is a swash plate compressor, which relies on the rotational motion of a swash plate that is inclined to the rotating shaft to drive the piston or piston rod to reciprocate to achieve gas compression.

[0003] Existing technologies, such as: CN215633598U, a high-strength rocker for automobile air-conditioning compressors, is provided with mounting grooves on both sides of the rocker body, mounting plates are installed in the mounting grooves, and multiple steel balls are arranged in the mounting plate, so that when the compressor is working, the steel balls are driven to squeeze the piston, avoiding the rocker body from directly contacting the piston, reducing the degree of wear of the rocker body, and increasing the service life of the rocker body, and by arranging mounting leaves on the outside of the mounting plate, and opening a fixing groove for docking the mounting leaves in the mounting groove, the mounting plate can be quickly maintained and replaced after a long period of use through the cooperation of simple bolts and nuts, avoiding the disadvantage of needing to replace the entire rocker, reducing the loss rate, avoiding excessive waste, and reducing cost expenditure. It has a good overall practical effect and is worthy of promotion and use in the existing market.

[0004] However, the device still has certain shortcomings when in use. When removing the mounting plate, the bolt needs to be tightened first so that the bolt and the nut can be separated before the mounting plate can be taken out, thereby reducing the disassembly efficiency. When lubrication is required, although the lubricant can flow along the connecting pipe to each steel ball groove, the flow efficiency is too low, which reduces the practicality.
