Description

Technical Field

[0001] This utility model relates to the field of automotive compressors, specifically a valve plate assembly for automotive air conditioning compressors. Background Technology

[0002] The valve plate assembly in an automotive air conditioning compressor is a crucial component ensuring the compressor's proper operation. The valve plate assembly typically includes an intake valve and an exhaust valve, whose function is to precisely control the intake and discharge of refrigerant, thereby regulating the temperature inside the vehicle. Currently, most automotive air conditioning compressors use valve plate assemblies made of thin metal sheets. While this traditional structure is lower in cost, it is prone to problems such as valve plate wear and breakage under high-intensity operating conditions, leading to decreased compressor cooling efficiency and even compressor damage.

[0003] With the continuous development of the automotive industry, the performance requirements for air conditioning compressors are becoming increasingly stringent. The shortcomings of traditional valve plate assemblies are becoming increasingly apparent, making it difficult to meet the demands of modern automobiles for efficient and reliable operation. Especially under high-temperature and high-pressure operating conditions, the fatigue resistance, corrosion resistance, and sealing performance of valve plate assemblies face severe challenges. Furthermore, with increasingly stringent environmental regulations, automotive air conditioning systems are increasingly choosing more environmentally friendly refrigerants, which places new demands on the materials and structure of valve plate assemblies.

[0004] To address the aforementioned issues, it is particularly important to develop a high-performance automotive air conditioning compressor valve plate assembly. Utility Model Content

[0005] The purpose of this invention is to provide a valve plate assembly for an automotive air conditioning compressor to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A valve plate assembly for an automotive air conditioning compressor includes a compressor. An upper seat and a lower seat are fixedly connected to the upper and lower parts of the outer wall of the compressor, respectively. An outer ring is fixedly connected to the front end of the compressor. A connecting rod is installed at the front end of the outer ring, and a connecting piece is fixedly connected to the top of the connecting rod. There are three sets of connecting pieces. Nuts are installed at the connecting parts of the three sets of connecting pieces. An outer rod is installed on the outer side of the front end of each nut. A triangular piece is fixedly connected to the bottom of the nut. An outer rod is fixedly connected to all four sides of the upper surface of the triangular piece. A connecting piece is fixedly connected to the rear part of the compressor.

[0008] As a further embodiment of this utility model: a pressure roller is fixedly connected to the bottom of the connecting piece, a front seat is fixedly connected to the end of the pressure roller away from the connecting piece, and a center seat is fixedly connected to the end of the front seat away from the pressure roller.

[0009] As a further embodiment of this utility model: the end of the center seat away from the front seat is fixedly connected to a rear seat, and mounting parts are installed around the top of the rear seat, with a connecting cap on the top of each mounting part.

[0010] As a further embodiment of this utility model: a connecting rod is hinged to the top of the connecting cap, a protruding piece is fixedly connected to the end of the connecting rod away from the connecting cap, and a mating plate is fixedly connected to the inner side of the protruding piece.

[0011] As a further embodiment of this utility model: a connecting plate is fixedly connected to the end of the docking plate away from the connecting rod, and a pressure plate is fixedly connected to the end of the connecting plate away from the docking plate.

[0012] As a further improvement of this utility model: the number of connecting rods and connecting caps is four sets, and all four sets of connecting caps and connecting rods are hinged.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] This utility model features an installation component mounted on the upper part of the rear seat cavity, used in conjunction with a connecting cap. A connecting rod hinged to the top of the connecting cap, along with a protruding piece, is fixed to the mating plate. The connecting plate connected to the top of the mating plate works in conjunction with a pressure plate. When the pressure plate rotates, it drives the connecting plate and the connected mating plate brake protruding piece to rotate, and also drives the connecting cap connected to the connecting rod to change the position of the installation component. Its structure is more optimized and its design is more reasonable.

[0015] In this utility model, the triangular piece located at the front end of the compressor is used in conjunction with the connecting piece. When the connecting piece rotates, it will drive the outer ring and the triangular piece connected by the outer rod to rotate. The outer rod installed on the top of the triangular piece is used in conjunction with the nut. When the connecting piece swings, it will drive the outer rod to rotate, and thus the triangular piece installed at the nut will rotate. Attached Figure Description
