Description

Technical Field

[0001] This invention relates to the field of compressor technology, and more particularly to a novel exhaust hose assembly for automotive air conditioning compressors. Background Technology

[0002] The compressor exhaust pipe not only serves to exhaust air within the compressor but also plays a role in reducing noise and vibration. Therefore, the stability and sealing of the connection between the exhaust pipe and the compressor body have a significant impact on the noise and vibration levels during compressor operation.

[0003] The inventors of this application have discovered the following problems in practical use: In actual use, the high-pressure gas discharged from the existing automotive air conditioning compressor exhaust hose assembly is prone to generating noise, causing noise pollution, and the high-speed airflow has a large impact on the pipe, affecting its service life.

[0004] Therefore, the present invention provides a novel automotive air conditioning compressor exhaust hose assembly to solve the problems mentioned above. Summary of the Invention

[0005] The purpose of this invention is to provide a novel exhaust hose assembly for an automotive air conditioning compressor to solve the problems mentioned in the background section.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A novel automotive air conditioning compressor exhaust hose assembly includes a connector for connecting to the compressor. A connecting sleeve is fixedly installed on the inner surface of the connector, and an L-tube is fixedly installed on the surface of the connecting sleeve. An L-groove is formed on the surface of the L-tube, and an arc-shaped groove is formed on the inner wall of the L-groove. A round tube is fixedly connected to the inner surface of the connecting sleeve, and a telescopic rod is fixedly connected to the inner wall of the L-tube. A spring is provided on the surface of the telescopic rod, and an annular block is fixedly installed on the inner surface of the telescopic rod. A metal head is provided on the inner surface of the round tube, and a hose body is provided on the inner surface of the metal head.

[0008] Preferably, when it is necessary to disassemble the hose body 11 and the metal head 10, the metal head 10 is slid, which drives the limiting post 16 to slide, thereby separating the limiting post 16 from the arc groove 5. At the same time, the metal head 10 and the limiting post 16 are rotated, and the spring 8 pushes the annular block 9 to slide. The annular block 9 pushes the metal head 10 to slide out, so that the hose body 11 and the metal head 10 can be disassembled.

[0009] As a further embodiment of the present invention, a groove is provided on the surface of the circular tube, and a rubber pad is provided inside the groove, and a damping sheet is fixedly connected to the surface of the rubber pad.

[0010] Preferably, by using spring 219 and damping plate 218 in conjunction with damping plate 14, the circular block 20 can be buffered when high-speed airflow impacts it, thus preventing damage to the inner wall of the pipe caused by the high-speed airflow impacting it.

[0011] As a further embodiment of the present invention, a concave tube is fixedly connected to the surface of the metal head, and a limiting post is fixedly connected to the surface of the concave tube. A limiting ring is fixedly connected to the inner wall of the metal head, and a damping plate is fixedly connected to the surface of the limiting ring. A spring is provided on the inner wall of the metal head, and a circular block is provided inside the metal head, with several sets of through holes opened inside the circular block.

[0012] Preferably, when a high-speed airflow impacts the pipe, the through hole 21 inside the circular block 20 can divert the high-speed airflow and prevent damage to the pipe.

[0013] As a further embodiment of the present invention, the surface of the damping plate one is in contact with the inner wall of the metal head, and the inner surface of the damping plate one is in contact with the surface of the circular block.

[0014] Preferably, by using damping plate 14 in conjunction with damping plate 28, the circular block 20 can be buffered when high-speed airflow impacts it.

[0015] As a further embodiment of the present invention, the inner wall of the metal head is fitted with the surface of the round tube, the round tube and the connecting sleeve are integrally formed, and the telescopic rod is fixed to the L-tube by bolts.

[0016] Preferably, when the hose body 11 needs to be replaced, the threaded head 26 can be turned to separate the threaded head 26 from the metal head 10, making it convenient to replace the hose body 11. This avoids the problem of having to replace the entire hose assembly when it is damaged, greatly avoiding waste of resources and improving the performance.

[0017] As a further embodiment of the present invention, a metal tube is fixedly installed on the surface of the metal head, and a threaded sleeve is connected to the surface of the metal tube by a thread. A conductive sheet is fixedly installed inside the threaded sleeve. A threaded ring is fixedly connected to the left end surface of the metal head, and a threaded head is connected to the surface of the threaded ring by a thread.

[0018] Preferably, when the metal head 10 needs to be installed, by engaging the limiting post 16 with the L groove 4, simultaneously sliding the metal head 10 and the limiting post 16, and rotating the limiting post 16 to a suitable position, the spring 8 pushes the annular block 9 to slide, causing the annular block 9 to push the metal head 10 to slide, so that the limiting post 16 on the surface of the metal head 10 engages with the inner wall of the arc groove 5, the metal head 10 can be installed with the connecting sleeve 2 and the connecting head 1, making the installation simpler.

[0019] As a further embodiment of the present invention, a limiting block is fixedly connected to the surface of the hose body, a graphite-lined resin layer is provided on the inner wall surface of the hose body, and an electrostatic connection block is fixedly installed on the surface of the hose body.

[0020] Preferably, when the high-speed airflow flows, it will rub against the inner surface of the hose body 11, causing the static electricity generated by the charge in the high-speed airflow to accumulate on the pipe wall. Since the metal head 10 is equipped with a conductive plate 24 and a conductive wire 29, the static electricity can be discharged, avoiding excessive static electricity accumulation and damage to the pipe.

[0021] As a further embodiment of the present invention, the surface of the conductive sheet is provided with conductive lines, the metal tube and the metal head are integrated into one structure, and both the conductive sheet and the electrostatic connection block are tin-plated copper busbars.

[0022] Preferably, since the inside of the hose body 11 is provided with a graphite inner resin layer 30 and an electrostatic connection block 28, static electricity can be further discharged.

[0023] As a further embodiment of the present invention, the surface of the limiting block contacts the inner wall of the threaded head, and the limiting block and the hose body are an integral structure.

[0024] Preferably, the hose body 11 can be separated from the metal head 10 by turning the threaded head 26, which facilitates the installation of hose bodies 11 and conductive wires 29 of different lengths.

[0025] Compared with related technologies, the novel automotive air conditioning compressor exhaust hose assembly provided by this invention has the following beneficial effects:

[0026] 1. This invention solves the technical problems of noise pollution caused by the discharge of high-pressure gas and the significant impact of high-speed airflow on the pipeline, which affects its service life, by setting up a circular block and through holes. The through holes inside the circular block can divert the high-speed airflow and avoid significant impact on the pipeline. Because a second spring and a second damping plate are set inside the metal head, in conjunction with the first damping plate, the circular block can be buffered when the high-speed airflow impacts it, resulting in better performance. The grooves and rubber pads on the surface of the circular tube improve the sealing between the metal head and the circular tube, resulting in better performance.

[0027] 2. When using this invention, the sliding metal head drives the limiting post to slide, thereby separating the limiting post from the arc-shaped groove. At the same time, rotating the metal head and the limiting post causes the spring to push the annular block to slide, and the annular block pushes the metal head out, which facilitates quick disassembly of the metal head and avoids the problem of needing to replace the entire hose when it is damaged. Disassembly is convenient, more energy-saving and environmentally friendly, and reduces maintenance costs.

[0028] 3. When using this invention, a conductive plate and a conductive wire are provided inside the metal head. When the high-speed airflow flows, it will rub against the inner surface of the hose body, causing the static electricity generated by the charge in the high-speed airflow to accumulate on the hose wall. It is practical. At the same time, the hose body can be separated from the metal head by turning the threaded head, which is convenient for installing hose bodies and conductive wires of different lengths.

[0029] In summary, this invention, through the through-holes inside the circular block, can divert high-speed airflow, preventing it from causing significant impact on the pipe. The presence of a second spring and a second damping plate inside the metal head, in conjunction with the first damping plate, buffers the circular block when it impacts. The presence of conductive plates and wires inside the metal head dissipates static electricity generated by the friction between the high-speed airflow and the inner surface of the flexible hose, thus improving its practicality.

[0037] To facilitate understanding of the present invention, a more comprehensive description will be given below with reference to the accompanying drawings. Typical embodiments of the present invention are shown in the drawings.

[0038] Example 1:

[0039] Reference Figure 1-6 As shown, the novel automotive air conditioning compressor exhaust hose assembly of the present invention includes a connector 1 for connecting to the compressor. A connecting sleeve 2 is fixedly installed on the inner surface of the connector 1, and an L-tube 3 is fixedly installed on the surface of the connecting sleeve 2. An L-groove 4 is formed on the surface of the L-tube 3, and an arc-shaped groove 5 is formed on the inner wall of the L-groove 4. A round tube 6 is fixedly connected to the inner surface of the connecting sleeve 2, and a telescopic rod 7 is fixedly connected to the inner wall of the L-tube 3. A spring 8 is provided on the surface of the telescopic rod 7, and an annular block 9 is fixedly installed on the inner surface of the telescopic rod 7. A metal head 10 is provided on the inner surface of the round tube 6, and a hose body 11 is provided on the inner surface of the metal head 10. When it is necessary to disassemble the hose body 11 and the metal head 10, by sliding the metal head 10, the metal head 10 drives the limiting post 16 to slide, thereby separating the limiting post 16 from the arc-shaped groove 5. At the same time, by rotating the metal head 10 and the limiting post 16, the spring 8 pushes the annular block 9 to slide, and the annular block 9 pushes the metal head 10 to slide out, so that the hose body 11 and the metal head 10 can be disassembled.

[0040] In this embodiment, refer to Figure 1-6 As shown, a groove 12 is provided on the surface of the circular tube 6, and a rubber pad 13 is provided inside the groove 12. A damping plate 14 is fixedly connected to the surface of the rubber pad 13. With the use of the spring 19 and the damping plate 18, the circular block 20 can be buffered when the high-speed airflow impacts the circular block 20, so as to avoid damage to the inner wall of the pipe when the high-speed airflow impacts it.

[0041] In this embodiment, refer to Figure 1-6 As shown, a concave tube 15 is fixedly connected to the surface of the metal head 10, and a limiting post 16 is fixedly connected to the surface of the concave tube 15. A limiting ring 17 is fixedly connected to the inner wall of the metal head 10, and a damping plate 18 is fixedly connected to the surface of the limiting ring 17. A spring 19 is provided on the inner wall of the metal head 10. A circular block 20 is provided inside the metal head 10, and several sets of through holes 21 are opened inside the circular block 20. When the high-speed airflow impacts the pipe, the through holes 21 inside the circular block 20 can divert the high-speed airflow and avoid damage to the pipe.

[0042] In this embodiment, refer to Figure 1-6 As shown, the surface of damping plate 14 is in contact with the inner wall of metal head 10, and the inner surface of damping plate 14 is in contact with the surface of circular block 20. When damping plate 14 is used in conjunction with damping plate 28, it can buffer the circular block 20 when high-speed airflow impacts it.

[0043] In this embodiment, refer to Figure 1-6As shown, the inner wall of the metal head 10 is in contact with the surface of the round tube 6. The round tube 6 and the connecting sleeve 2 are integrally formed. The telescopic rod 7 is fixed to the L tube 3 by bolts. When the hose body 11 needs to be replaced, the threaded head 26 can be turned to separate the threaded head 26 from the metal head 10, which facilitates the replacement of the hose body 11 and avoids the problem of having to replace the entire hose assembly when it is damaged. This greatly avoids the waste of resources and improves the performance.

[0044] Example 2:

[0045] Reference Figure 1-6 As shown, the difference from embodiment 1 is that a metal tube 22 is fixedly installed on the surface of the metal head 10, and a threaded sleeve 23 is threadedly connected to the surface of the metal tube 22. A conductive sheet 24 is fixedly installed inside the threaded sleeve 23. A threaded ring 25 is fixedly connected to the left end surface of the metal head 10, and a threaded head 26 is threadedly connected to the surface of the threaded ring 25. When the metal head 10 needs to be installed, the limiting post 16 is engaged with the L groove 4, and the metal head 10 and the limiting post 16 are slid simultaneously. The limiting post 16 is rotated to a suitable position, and the spring 8 pushes the annular block 9 to slide, so that the annular block 9 pushes the metal head 10 to slide, and the limiting post 16 on the surface of the metal head 10 is engaged with the inner wall of the arc groove 5. The metal head 10 can then be installed with the connecting sleeve 2 and the connecting head 1, making the installation simpler.

[0046] In this embodiment, refer to Figure 1-6 As shown, a limiting block 27 is fixedly connected to the surface of the hose body 11, a graphite-lined resin layer 30 is provided on the inner wall surface of the hose body 11, and an electrostatic connection block 28 is fixedly installed on the surface of the hose body 11. When the high-speed airflow flows, it will rub against the inner surface of the hose body 11, causing the static electricity generated by the charge in the high-speed airflow to accumulate on the pipe wall. Since the metal head 10 is provided with a conductive sheet 24 and a conductive wire 29, the static electricity can be discharged to avoid excessive static electricity accumulation and damage to the pipe.

[0047] In this embodiment, refer to Figure 1-6 As shown, the conductive sheet 24 has conductive wires 29 on its surface. The metal tube 22 and the metal head 10 are integrated. The conductive sheet 24 and the electrostatic connection block 28 are both tin-plated copper busbars. Since the inside of the flexible tube body 11 is provided with a graphite inner resin layer 30 and an electrostatic connection block 28, static electricity can be further discharged.

[0048] In this embodiment, refer to Figure 1-6 As shown, the surface of the limiting block 27 contacts the inner wall of the threaded head 26. The limiting block 27 and the hose body 11 are an integral structure. By turning the threaded head 26, the hose body 11 can be separated from the metal head 10, which facilitates the installation of hose bodies 11 and conductive wires 29 of different lengths.

[0049] The working principle of this invention is as follows: First, the connector 1 is installed in a suitable position inside the car. When high-speed airflow impacts the pipe, the through hole 21 inside the round block 20 can divert the high-speed airflow. The second spring 19 and the second damping plate 18, in conjunction with the first damping plate 14, can buffer the round block 20 when it impacts the pipe, preventing damage to the inner wall of the pipe and affecting its service life. When it is necessary to disassemble the hose body 11 and the metal head 10, the metal head 10 is slid, causing the limiting post 16 to slide, thus separating the limiting post 16 from the arc groove 5. At the same time, rotating the metal head 10 and the limiting post 16 causes the spring 8 to push the annular block 9 to slide, and the annular block 9 pushes the metal head 10 out, allowing the hose body 11 and the metal head 10 to be disassembled. When it is necessary to replace the hose body 11, the threaded head 26 is turned to separate the threaded head 26 from the metal head 10, facilitating the replacement of the hose body 11 and avoiding the problem of having to replace the entire hose assembly when it is damaged. This design avoids resource waste and improves performance. When installing the metal head 10, the limiting post 16 engages with the L-groove 4, while simultaneously sliding the metal head 10 and the limiting post 16 and rotating the limiting post 16 to the appropriate position. The spring 8 pushes the annular block 9 to slide, causing the annular block 9 to push the metal head 10 to slide, thus engaging the limiting post 16 on the surface of the metal head 10 with the inner wall of the arc groove 5. This allows the metal head 10 to be installed with the connecting sleeve 2 and the connecting head 1, making installation simpler. When high-speed airflow flows, it rubs against the inner surface of the hose body 11, causing static electricity to accumulate on the pipe wall. Since the metal head 10 has a conductive plate 24 and a conductive wire 29 inside, it can conduct away static electricity, preventing excessive static electricity accumulation and damage to the pipe. At the same time, since the hose body 11 has a graphite inner resin lining layer 30 and a static electricity connecting block 28 inside, it can further conduct away static electricity. The use of the conductive plate 24 in conjunction with the threaded sleeve 23 facilitates the installation of hose bodies 11 and conductive wires 29 of different lengths.
