Description

Technical Field

[0001] The present invention relates to the technical field of swash plate compressors, in particular to a swash plate automobile air-conditioning compressor. Background Art

[0002] With the vigorous development of the automobile industry and people's increasing demand for automobile comfort, the performance and reliability of automobile air-conditioning systems, as key components to enhance the driving experience, have received widespread attention. The automobile air-conditioning compressor, as the core power source of the air-conditioning system, undertakes the important task of compressing and transporting refrigerant. Its performance directly determines the cooling effect and operating efficiency of the air-conditioning system. The swash plate automobile air-conditioning compressor has been widely used in the field of automobile air-conditioning due to its unique structure and working principle. It is mainly composed of a main shaft, a swash plate, a piston, a cylinder and other components. When the compressor is running, the main shaft drives the swash plate to rotate. The special angle design of the swash plate enables the piston connected to it to perform reciprocating linear motion in the cylinder, thereby realizing the refrigerant suction, compression and discharge process.

[0003] In the prior art, the reciprocating motion of the compressor piston causes a significant difference in the intake and exhaust speeds. When the piston moves outward, the pressure in the cylinder decreases, and the refrigerant slowly flows into the cylinder under a small pressure difference, resulting in a slow intake speed. However, when the piston moves inward to compress the refrigerant, the pressure in the cylinder suddenly increases, and the refrigerant is discharged at a higher speed. The exhaust speed is much faster than the intake speed. This speed difference causes the exhaust valve plate to bear huge impact forces when opening and closing. The high-speed refrigerant gas frequently impacts the valve plate, causing increased wear on the valve plate surface and even cracks or breakage. When the valve plate is worn, it does not seal tightly, causing the compressed high-temperature and high-pressure refrigerant gas to leak, reducing the exhaust efficiency of the compressor and thus affecting the cooling capacity of the entire refrigeration system. In addition, the prior art lacks the ability to monitor and adjust the intake temperature and airflow speed. During the intake process, it is impossible to accurately obtain airflow speed and temperature information in real time, making it difficult to adjust the intake state in a timely manner according to actual operating conditions. When the intake temperature is too low, the intake temperature cannot be effectively increased, which may affect the performance and stability of the refrigeration system. Summary of the Invention

The upper surface of the circulating air warehouse 2 is provided with an outlet pipe 5 and an inlet pipe 6. A steering valve for switching the communication path between the compressed air pipe 13 and the outlet pipe 5 and the inlet pipe 6 is provided inside the circulating air warehouse 2. An additional mechanism is also provided on the upper surface of the circulating air warehouse 2, and the additional mechanism includes an air induction component and a detection component; During use, the transmission disc 4 is connected to the external power output device through a transmission belt to drive the rotating shaft 3 to rotate. The inclined disc 11 drives multiple connected pistons 12 to reciprocate as the rotating shaft 3 rotates, thereby realizing the compression and transportation of the refrigerant. The air bleed assembly serves as an auxiliary regulating mechanism to enable the equipment to achieve better use effects during operation.

[0018] The air bleed assembly includes: an air outlet additional pipe 7 and an air inlet additional pipe 8, the air outlet additional pipe 7 is fixedly mounted on the upper surface of the air outlet pipe 5, the air inlet additional pipe 8 is fixedly mounted on the upper surface of the air inlet pipe 6, a central connecting pipe 9 is provided between the air outlet additional pipe 7 and the air inlet additional pipe 8, a sliding base 15 is provided on the inner bottom surface of the central connecting pipe 9, a driving motor 21 is provided inside the sliding base 15, an engaging screw 17 is provided on the output end of the driving motor 21, and an engaging connecting plate 28 is engaged with the surface of the engaging screw 17, and two limiting fixing plates 19 for limiting the range of motion of the engaging connecting plate 28 are also provided on the surface of the engaging screw 17, a gas main pipe 18 is provided at the center of the upper end of the engaging connecting plate 28, a compression inner pipe 29 is provided inside the gas main pipe 18, and one end of the gas main pipe 18 is provided with A telescopic tube 24 is provided with an outlet connecting tube 22 at one end of the telescopic tube 24 away from the gas main pipe 18. The outlet connecting tube 22 is located at the center of the side surface of the connection between the air inlet additional pipe 8 and the central connecting pipe 9. An opening for facilitating the installation of the outlet connecting tube 22 is provided at the center of the side surface of the connection between the air inlet additional pipe 8 and the central connecting pipe 9. An external elbow 23 is provided at the end of the air outlet connecting tube 22 away from the telescopic tube 24. An air bleed pipe 25 is provided at the end of the gas main pipe 18 away from the external elbow 23. A window is also provided on the side surface of the connection between the central connecting pipe 9 and the air outlet additional pipe 7 to facilitate the passage of the air bleed pipe 25. An air inlet opening is provided on the bottom surface of the air bleed pipe 25. Slide bars are also provided on both sides of the bottom surface of the air bleed pipe 25. A sliding base plate 16 that cooperates with the slide bar is also provided on the inner bottom surface of the central connecting pipe 9. In the prior art, when the piston moves outward, the volume of the cylinder increases and the pressure decreases, and the refrigerant enters the cylinder from the air inlet. At this time, the pressure in the cylinder is only slightly lower than the pressure in the external refrigerant pipeline. The pressure difference is relatively small, and the intake process is a relatively slow charging process. The refrigerant gradually flows into the cylinder under the action of the pressure difference, so the intake speed is slow. When the piston moves inward to compress the refrigerant, the refrigerant in the cylinder is rapidly compressed to a high-temperature and high-pressure gas state. At the moment of discharge, the pressure in the cylinder is much higher than the pressure in the external pipeline. This large pressure difference will cause the refrigerant to be discharged from the cylinder at a higher speed, so the exhaust speed is fast. When the exhaust speed is much faster than the intake speed, the exhaust valve plate will be subjected to greater impact force when opening and closing. The high-speed refrigerant gas impacts the valve plate, causing the valve plate to be frequently subjected to large stress, resulting in increased wear on the valve plate surface, and even cracks or breakage. Valve plate wear will lead to loose sealing, causing the compressed high-temperature and high-pressure refrigerant gas to leak, reducing the exhaust efficiency of the compressor, and thus affecting the refrigeration capacity of the entire refrigeration system. The additional mechanism in this solution is used to solve the above situation. When in use, the signal processor automatically sends a start command to the drive motor 21 of the air bleed assembly, so that the drive motor 21 starts to run, driving the meshing screw 17 to rotate. Since there is a threaded fit between the meshing screw 17 and the meshing connecting plate 28, the rotation of the meshing screw 17 will cause the meshing connecting plate 28 to move horizontally along the sliding base 15. The movement of the meshing connecting plate 28 pushes the gas transmission main pipe 18 and the air bleed pipe 25 to move as a whole toward one side of the air outlet additional pipe 7, and stretches the telescopic pipe 24. At the same time, the air bleed pipe 25 slides on the sliding base plate 16 through the sliding strip on its bottom surface. At this time, the air bleed pipe 25 enters the interior of the air outlet additional pipe 7 from the interior of the central connecting pipe 9, gradually exposing the air inlet opening of the air bleed pipe 25 to the outlet In the outlet air flow inside the air additional pipe 7, at this time, one of the high-temperature and high-pressure refrigerant outlet air flows in the central connecting pipe 9 enters the inside of the air bleed pipe 25 through the air inlet opening of the air bleed pipe 25. After the airflow enters the compression inner pipe 29 of the gas transmission main pipe 18, since the opening at one end of the compression inner pipe 29 is smaller, the airflow will be compressed after passing through the compression inner pipe 29, so that the airflow speed will be initially increased. Finally, after passing through the air outlet connecting pipe 22 and the telescopic tube 24, the airflow becomes a guided airflow and enters the inside of the air intake additional pipe 8, and contacts the intake air flow inside the air intake additional pipe 8. Because the flow rate of the guided airflow is faster than the intake airflow after compression, it will drive it under contact with the intake airflow, so that the speed of the intake airflow is increased, and the speed difference between the intake and outlet airflows on both sides is narrowed.

[0019] The detection component includes: a central fixing plate 20, the central fixing plate 20 is fixedly installed at the inner center of the air intake additional pipe 8, the bottom surface of the central fixing plate 20 is provided with an additional bottom plate 30, the center of the central fixing plate 20 is provided with a detection fan blade 31, the bottom surface of the detection fan blade 31 is provided with a small wind turbine 32, the bottom surface of the small wind turbine 32 is connected to the upper surface of the additional bottom plate 30, the upper surface of the central fixing plate 20 is also provided with a temperature detector 33, the inner side surface of the central connecting pipe 9 is provided with a bearing plate body 35, the upper surface of the bearing plate body 35 is provided with a battery 34, one side surface of the battery 34 is provided with a signal controller, the battery 34 and the small wind turbine 32 are connected by a cable, and the two side surfaces of the battery 34 are provided with connecting wires Tube 36, a power transmission cable is provided inside the connecting wire tube 36, and the other end of the power transmission cable is connected to the drive motor 21. The detection component also includes a connecting ring tube 39, which is located in the middle section of the gas transmission main tube 18. The upper surface of the connecting ring tube 39 is provided with an acceleration ring tube 27, and the center of the acceleration ring tube 27 is provided with an acceleration fan blade 37. A meshing support plate 41 is provided on one side surface of the connecting ring tube 39, and a small screw 40 is meshed at the center of the meshing support plate 41. The surface of the small screw 40 is also provided with two limiting rings 42 for limiting the range of motion of the meshing support plate 41. The upper end of the limiting ring 42 is provided with a servo motor 38, and the upper surface of the servo motor 38 is provided with a sliding block 26. The inner upper surface of the central connecting tube 9 is also provided with a sliding groove that cooperates with the sliding block 26; The detection component serves as an intelligent monitoring unit in the device and is used to monitor the intake air temperature and air flow velocity in real time. When the refrigerant gas flows through the intake additional pipe 8, the air flow impacts the detection blade 31, causing it to rotate. The rotation of the detection blade 31 drives the rotor of the small wind turbine 32 to rotate, converting the kinetic energy of the air flow into electrical energy. The electrical energy is transmitted to the battery 34 for storage through a cable, and at the same time reflects the air flow velocity information (the output power of the wind turbine is positively correlated with the air flow velocity). The signal processor indirectly obtains the air flow velocity data by monitoring the charging state of the battery 34 or the output power of the small wind turbine 32. This data can be used to evaluate the effect of the air bleed component on improving the intake air velocity. The temperature detector 33 monitors the temperature of the refrigerant gas in real time in the intake additional pipe 8. The temperature detector 33 converts the temperature data into an electrical signal and transmits it to the signal processor through a cable. The signal processor processes and analyzes the temperature data to determine Whether the current intake air temperature meets the system requirements, and whether the high-temperature and high-pressure gas injected by the air bleed assembly effectively increases the intake air temperature. When it is detected that the temperature is too low, the connecting ring tube 39 in the middle section of the gas supply main pipe 18 and the acceleration ring tube 27 thereon play a role. The servo motor 38 is started according to the instruction of the signal processor to drive the small screw 40 to rotate. The rotation of the small screw 40 causes the meshing support plate 41 to move axially along the small screw 40, thereby changing the position of the acceleration ring tube 27 and the acceleration fan blade 37, so that the acceleration fan blade 37 enters the interior of the gas supply main pipe 18. When the high-speed airflow passes through the acceleration fan blade 37, the acceleration fan blade 37 further accelerates the airflow, so that the airflow passes through the outlet connecting pipe 22 and the external elbow 23 at a higher speed, so that more compressed high-temperature and high-pressure refrigerant gas is injected into the intake additional pipe 8 through the external elbow 23 and combines with the intake airflow, so that the temperature of the intake airflow becomes appropriate.

[0020] The working principle of the present invention is: During use, the transmission disc 4 is connected to the external power output device through a transmission belt to drive the rotating shaft 3 to rotate. The inclined disc 11 drives the multiple connected pistons 12 to reciprocate as the rotating shaft 3 rotates, thereby achieving the compression and transportation of the refrigerant. The air bleed assembly serves as an auxiliary regulating mechanism to achieve better performance during the operation of the equipment. When in use, the signal processor automatically sends a start command to the drive motor 21 of the air bleed assembly, so that the drive motor 21 starts to run, driving the meshing screw 17 to rotate. Since there is a threaded fit between the meshing screw 17 and the meshing connecting plate 28, the rotation of the meshing screw 17 will cause the meshing connecting plate 28 to move horizontally along the sliding base 15. The movement of the meshing connecting plate 28 pushes the gas supply main 18 and the air bleed pipe 25 to move as a whole toward one side of the air outlet additional pipe 7, and stretches the telescopic pipe 24. At the same time, the air bleed pipe 25 is moved by The sliding strip on its bottom surface slides on the sliding base plate 16. At this time, the air duct 25 enters the interior of the outlet auxiliary pipe 7 from the interior of the central connecting pipe 9. Finally, after passing through the outlet connecting pipe 22 and the telescopic pipe 24, the airflow is transformed into the guide airflow and enters the interior of the air intake auxiliary pipe 8. There, it contacts the intake airflow inside the air intake auxiliary pipe 8. Because the flow rate of the guide airflow is faster than that of the intake airflow after compression, the contact with the intake airflow will drive the intake airflow, thereby increasing the speed of the intake airflow and narrowing the speed difference between the inlet and outlet airflows on both sides. The detection component serves as an intelligent monitoring unit in the device, and is used to monitor the intake air temperature and airflow velocity in real time. When the refrigerant gas flows through the intake additional pipe 8, the airflow impacts the detection blade 31, causing it to rotate. The rotation of the detection blade 31 drives the rotor of the small wind turbine 32 to rotate, converting the kinetic energy of the airflow into electrical energy, which is transmitted to the battery 34 for storage through a cable, and at the same time reflects the airflow velocity information (the output power of the wind turbine is positively correlated with the airflow velocity). The signal processor indirectly obtains the airflow velocity data by monitoring the charging status of the battery 34 or the output power of the small wind turbine 32. This data can be used to evaluate the effect of the air bleed component on improving the intake air velocity. The temperature detector 33 monitors the temperature of the refrigerant gas in real time in the intake additional pipe 8. The temperature detector 33 converts the temperature data into an electrical signal and transmits it to the battery 34 through the cable. The cable transmits the data to the signal processor, which processes and analyzes the temperature data to determine whether the current intake air temperature meets the system requirements and whether the high-temperature and high-pressure gas injected by the air bleed assembly has effectively increased the intake air temperature. When it is detected that the temperature is too low, the servo motor 38 starts according to the instruction of the signal processor, driving the small screw 40 to rotate, thereby changing the position of the acceleration ring tube 27 and the acceleration fan blade 37, so that the acceleration fan blade 37 enters the interior of the gas supply main pipe 18. When the high-speed airflow passes through the acceleration fan blade 37, the acceleration fan blade 37 further accelerates the airflow, so that the airflow passes through the air outlet connecting pipe 22 and the external bend 23 at a higher speed, so that more compressed high-temperature and high-pressure refrigerant gas is injected into the intake additional pipe 8 through the external bend 23 and combined with the intake airflow, so that the temperature of the intake airflow becomes suitable.
