Description

Technical Field

[0001] This utility model relates to the field of compressor valve plates, and more specifically to a novel compressor valve plate. Background Technology

[0002] With dwindling energy resources and increasing environmental pollution, new energy vehicles are receiving strong government support due to their environmentally friendly and energy-saving characteristics. Electric compressors, as a crucial component of new energy vehicles, play a vital role.

[0003] Currently, scroll electric compressors are widely used in the air conditioning systems of new energy vehicles to provide cooling and heating functions for the vehicle interior, meeting the needs of a comfortable environment. They are also used in automotive braking systems, turbocharging systems, etc., to provide compressed air for related equipment. The compressor includes a scroll plate, motor, housing, bracket, eccentric shaft, anti-rotation mechanism, back pressure chamber, suction port, discharge port, etc. These components work together to ensure the normal operation of the compressor.

[0004] When the scroll electric compressor is working, gas is drawn into the periphery of the stationary scroll plate through the air filter. At this time, the crescent-shaped space between the moving and stationary scroll plates gradually increases, forming a low-pressure area. External gas enters these spaces under the action of the pressure difference. Driven by the motor, the moving scroll plate rotates around the stationary scroll plate in a plane with a very small radius. Due to the relative motion of the moving and stationary scroll plates, the volume of the crescent-shaped compression chamber gradually decreases, and the gas inside the chamber is gradually compressed, with the pressure and temperature continuously increasing. When the volume of the compression chamber decreases to a certain extent, the compressed high-pressure gas is continuously discharged through the axial hole of the central component of the stationary scroll plate and enters the subsequent refrigeration or other system circuits.

[0005] In scroll electric compressors, a certain gap is often maintained between moving parts or between moving parts and stationary parts to achieve sealing. Gas passing through the gap will inevitably cause leakage, which limits the ability of rotary compressors to achieve a large compression ratio. The opening and closing of the valves in scroll electric compressors must be strictly controlled. When the valves are working, they are subjected to high-frequency alternating loads. The larger the cross-section of the middle section of the valve, the relatively poor the elasticity of the middle section, resulting in insufficient fatigue performance and affecting the sealing performance at the end. If the valve cantilever is slotted, the clearance will increase, reducing the compressor's suction efficiency. Utility Model Content

The stabilizing part is located at the end of the valve plate body away from the connecting part. The valve plate body is provided with two sets of positioning holes and one set of connecting holes.

[0009] Furthermore, the connecting portion includes a first portion, a second portion, and a third portion that are parallel to each other and sequentially arranged on the same side of the valve plate body. The width of the first portion is smaller than that of the third portion, and the width of the third portion is smaller than that of the second portion.

[0025] In this embodiment, a novel compressor valve includes a valve body 100, a connecting portion 200, a limiting portion 300, and a stabilizing portion 400. The valve body 100 is fixedly connected to the connecting portion 200 and the stabilizing portion 400, respectively. The limiting portion 300 is located at the end of the connecting portion 200 away from the valve body 100. The connecting portion 200 is provided with an arc-shaped segment 500 protruding from the valve body 100 at the end near the valve body 100. The stabilizing portion 400 is located at the end of the valve body 100 away from the connecting portion 200. The valve body 100 is provided with two sets of positioning holes 600 and one set of connecting holes 700.

[0026] The connecting portion 200 has an arc-shaped segment 500 protruding from the valve body 100 at one end near the valve plate body 100. This arc-shaped segment 500 effectively disperses the stress at the connection between the connecting portion 200 and the valve body 100. Since the compressor valve plate operates under repeated opening and closing actions, this arc-shaped structure reduces fatigue damage to the connecting portion 200 caused by frequent stress. Each time the valve plate opens and closes, the arc-shaped segment 500 of the connecting portion 200 better adapts to changes in force direction, making the material at the connecting portion 200 less prone to fatigue damage such as cracks during long-term operation, thus extending the service life of the valve plate. The design of the arc-shaped segment 500 protruding from the valve body 100 also guides airflow. When gas flows through the valve plate, the arc-shaped segment 500 allows the airflow to pass more smoothly through the transition area between the connecting portion 200 and the valve body 100, reducing airflow turbulence. This reduces airflow resistance and improves the compressor's operating efficiency. The presence of the arc segment 500 provides some positioning assistance for valve plate installation. When installing the valve plate into the corresponding position on the compressor, the installer can more accurately determine the installation direction and angle of the valve plate by using the position and shape of the arc segment 500, ensuring the correct fit between the valve plate and other components. Simultaneously, when connecting with other components, the arc segment 500 provides a certain amount of tolerance, making it easier for the valve plate to adapt to adjacent components during installation, reducing component damage or malfunctions caused by installation errors.

[0027] The limiting part 300 is located at the end of the connecting part 200 away from the valve plate body 100, and has a circular structure with a diameter larger than the width of the corresponding connecting part 200. During the movement of the valve plate, the limiting part 300 can limit excessive displacement of the valve plate. When the valve plate is subjected to a large airflow impact or other external force, the limiting part 300 can prevent the valve plate from leaving its normal working position, ensuring the normal operation of the compressor and avoiding malfunctions caused by excessive valve plate displacement.

[0028] In one or more possible embodiments of this utility model, the connecting portion 200 includes a first portion 210, a second portion 220, and a third portion 230 that are parallel to each other and sequentially arranged on the same side of the valve plate body 100. The width of the first portion 210 is smaller than that of the third portion 230, and the width of the third portion 230 is smaller than that of the second portion 220. The limiting portion 300 has a circular structure, and the diameter of the limiting portion 300 is larger than the width of the corresponding connecting portion 200. The connecting portion 200 is composed of the first portion 210, the second portion 220, and the third portion 230, and they are arranged in parallel to each other in sequence. This multi-layered structure and the width variation (the width of the first portion 210 is smaller than that of the third portion 230, and the width of the third portion 230 is smaller than that of the second portion 220) can increase the stability of the connection. When the valve plate is subjected to pressure changes and airflow impacts during the operation of the compressor, this structure can better distribute the force and prevent the connecting portion 200 from being damaged due to force concentration.

[0029] In one or more possible embodiments of this utility model, the first part 210 and the second part 220 are arranged in an arc-shaped fit with the valve body 100, and the distance between the first part 210 and the second part 220 is smaller than the distance between the second part 220 and the third part 230. The arc-shaped fit between the first part 210 and the second part 220 and the valve body 100 reduces stress concentration compared to a right-angle connection. Under frequent pressure changes and mechanical vibration, this structure can effectively reduce the risk of material fatigue and damage caused by stress concentration, thereby extending the service life of the valve. Furthermore, the smaller distance between the first part 210 and the second part 220 compared to the distance between the second part 220 and the third part 230 may help the connection part 200 adaptively adjust the stress distribution according to the force under different working conditions.

[0030] In one or more possible embodiments of this utility model, the two positioning holes 600 are located on both sides of the connecting hole 700, and the two positioning holes 600 and the connecting hole 700 are arranged in a triangle. The valve body 100 is provided with two sets of positioning holes 600 and one set of connecting holes 700, with the two positioning holes 600 located on both sides of the connecting hole 700 in a triangular arrangement. This triangular layout facilitates precise positioning of the valve body during installation, similar to the stability principle of a triangle, ensuring the accuracy and stability of the valve body's installation position. Installers can quickly determine the installation direction and position of the valve body through the positioning holes 600, improving installation efficiency.

[0031] In one or more possible embodiments of this utility model, the stabilizing part 400 is a tongue-shaped structure with its width reduced at the connection point with the valve plate body 100 at the end furthest from the valve plate body 100, forming a bend. This tongue-shaped structure can provide good elastic support when subjected to pressure and vibration. It can absorb and buffer the vibration and impact forces generated during the operation of the compressor to a certain extent, reduce the swaying and displacement of the valve plate, and thus ensure the stability of the valve plate during operation.

[0032] In one or more possible embodiments of this utility model, the connection between the stabilizing part 400 and the valve plate body 100 is arc-shaped. This arc-shaped connection also reduces stress concentration. During the frequent opening and closing of the valve plate, the arc-shaped connection effectively prevents damage to the connection part 200 due to stress concentration, allowing the stabilizing part 400 to better perform its function of stabilizing the valve plate.

The protection content of the specific embodiments is merely an explanation of the protection scope of the claims of this utility model.
