Description

Technical Field

[0001] This utility model relates to the field of flange technology, and more specifically, to a split mounting flange for the housing of a refrigeration compressor for new energy vehicles. Background Technology

[0002] In the development of new energy vehicles, the refrigeration compressor is the core of the refrigeration system, and the split mounting flange is a key component in the air conditioning system of new energy vehicles used to connect the refrigeration compressor housing to the vehicle body or other components. Its core feature is the adoption of a split structure design, and its main function is to achieve stable installation of the compressor, power transmission, and vibration and noise reduction.

[0003] Existing split flanges use simple bolt connections, relying solely on the fit between bolt holes and bolts for positioning. Due to the gap between bolt holes and bolts, there is a lack of precise guiding structures during installation, making it impossible to ensure accurate alignment between the flange and components such as the refrigeration compressor housing and vehicle body. Furthermore, during bolt tightening, the flange's circumferential and radial offset cannot be effectively limited, making it difficult to accurately control the installation position. This can lead to positional deviations after compressor installation, affecting the normal connection of refrigerant pipelines and causing refrigerant leaks. Utility Model Content

[0004] In order to overcome the above-mentioned defects of the prior art, this utility model provides a split mounting flange for the housing of a refrigeration compressor for new energy vehicles, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A split mounting flange for the housing of a refrigeration compressor for new energy vehicles includes a first flange ring and a second flange ring. The first flange ring is disposed on one side of the second flange ring. A slot is provided on one side of both the first flange ring and the second flange ring. A plug is inserted into the slot. An upper flange ring is fixedly disposed on one side of one of the plugs, and a lower flange ring is fixedly disposed on one side of the other upper flange ring. A connecting mechanism is provided on one side of the lower flange ring.

[0007] The connecting mechanism includes multiple positioning grooves formed on the surfaces of the second flange ring and the lower flange ring. Positioning pins are inserted into the interior of the positioning grooves. Sealing grooves are formed on the surfaces of the second flange ring and the lower flange ring. Sealing lips are inserted into the interior of the sealing grooves. Threaded openings are formed on the surfaces of the insert block, the first flange ring, and the second flange ring. A first bolt is threaded into the interior of the threaded opening.

[0008] By adopting the above technical solution: the combination design of slot and plug allows the flange to be quickly assembled and disassembled, improving production efficiency and maintenance convenience. Moreover, the connection design of the positioning column and sealing lip not only ensures the precise alignment of each flange ring, but also enhances the sealing performance and prevents refrigerant leakage.

[0009] As a further description of the above technical solution: both the first flange ring and the second flange ring have embedded grooves on their surfaces, the first bolt matches the embedded groove, one end of the positioning post and the sealing lip are respectively connected to the bottom of the first flange ring and the upper flange ring, and multiple bolt holes are opened on the surfaces of the first flange ring, the second flange ring, the upper flange ring and the lower flange ring, and the internal threads of the bolt holes are connected to the second bolts, and a sealing gasket is fixedly installed between the second bolts and the first flange ring and the upper flange ring.

[0010] By adopting the above technical solution: the fitting of the embedded groove with the first bolt ensures a tight connection and a flat surface, avoiding protrusions from interfering with the installation of other components. The second bolt, in conjunction with the bolt hole, achieves a stable connection of the multi-layer flange rings, enhancing the overall structural strength, while improving installation convenience and maintenance efficiency.

[0011] As a further description of the above technical solution: both the bottom of the second flange ring and the lower flange ring are fixedly provided with an elastic buffer layer, which is made of butyl rubber.

[0012] The surface of the elastic buffer layer has multiple evenly distributed arc-shaped grooves, and the interior of the arc-shaped grooves is filled with damping material made of polyurethane. The first flange ring, the second flange ring, the upper flange ring, and the lower flange ring are all made of high-strength aluminum alloy, and the sealing lip is made of nitrile rubber.

[0013] By adopting the above technical solution: an elastic buffer layer is fixedly provided at the bottom of both the second flange ring and the lower flange ring, and the elastic buffer layer is made of butyl rubber.

[0014] The surface of the elastic buffer layer has multiple evenly distributed arc-shaped grooves, and the interior of the arc-shaped grooves is filled with damping material, which can be made of polyurethane. The first flange ring, the second flange ring, the upper flange ring, and the lower flange ring are all made of high-strength aluminum alloy, and the sealing lip is made of nitrile rubber.

[0015] As a further description of the above technical solution: the butyl rubber elastic buffer layer absorbs compressor vibration, reduces noise transmission, and improves driving comfort. Moreover, the polyurethane damping material in the arc groove further consumes vibration energy, suppresses resonance, and extends component life. The composite material design enables the flange to maintain stable performance under complex working conditions such as high temperature and vibration, thereby improving system reliability.

[0016] The technical effects and advantages of this utility model are as follows:

[0017] 1. By setting up a connection mechanism, multiple beneficial effects are achieved compared with existing technologies. When the components are initially assembled, the slot and plug cooperate to facilitate assembly. The first bolt strengthens the connection strength. The embedded groove design ensures a flat surface, which is conducive to subsequent installation and sealing. Moreover, the precise cooperation between the positioning column and the positioning groove can effectively avoid installation deviation and improve the installation accuracy and stability of the flange. The sealing structure composed of the sealing lip and the sealing groove can effectively block the intrusion of external impurities and prevent the leakage of internal refrigerant and other media, ensuring the normal operation of the compressor. In addition, the split structure makes the connection between the second flange ring, the lower flange ring and the compressor housing, and the first flange ring, the upper flange ring and the vehicle body or bracket more flexible. It not only facilitates disassembly and maintenance, but also isolates vibration to a certain extent, reduces noise, and improves the overall performance and user experience of new energy vehicles.

[0018] 2. By incorporating bolt holes, a second bolt, an elastic buffer layer for the sealing gasket, and damping material, this technology significantly improves connection stability and performance compared to existing technologies. Multiple bolt holes, in conjunction with the second bolt, form dense fastening points, greatly enhancing the connection strength between flange rings and resisting dynamic stress during compressor operation. Furthermore, the addition of the sealing gasket, combined with the sealing lip structure, strengthens the sealing system from a dual-dimensional perspective, effectively eliminating the risk of refrigerant leakage and ensuring the safe operation of the refrigeration system. Secondly, the elastic buffer layer, made of butyl rubber, with its high elasticity, efficiently absorbs compressor vibration energy, significantly reducing noise transmission to the vehicle body and improving ride comfort. The polyurethane damping material filled in the arc-shaped groove further dissipates vibration energy, changes the vibration frequency, suppresses resonance, reduces wear and fatigue of components caused by vibration, and extends the service life of the flange and compressor, providing a reliable guarantee for the stable operation of the refrigeration system in new energy vehicles.
