Description

Technical Field

[0001] This utility model belongs to the field of corrugated pipe technology, and particularly relates to an automotive corrugated pipe with anti-clogging function and a flame-retardant corrugated pipe. Background Technology

[0002] The primary significance of using bellows in automotive air intake systems lies in their superior flexibility and extensibility. This allows them to effectively absorb vibrations and thermal expansion and contraction stresses from the engine or exhaust system, reducing the impact of mechanical loads on pipe connections and thus improving system durability. Simultaneously, the bellows' corrugated structure reduces airflow noise and adapts to complex spatial layouts. Anti-clogging design is crucial because the air intake system is constantly exposed to high temperatures, carbon deposits, and particulate matter. Anti-clogging structures (such as special filters, self-cleaning channels, or optimized airflow designs) significantly reduce carbon deposits and foreign matter buildup, preventing increased exhaust back pressure due to reduced pipe cross-sectional area, thereby preventing engine power loss, increased fuel consumption, or worsened emissions. Furthermore, anti-clogging design reduces maintenance frequency, extends component life, and ensures smooth airflow for systems such as Exhaust Gas Recirculation (EGR), ultimately guaranteeing vehicle performance, environmental friendliness, and reliability. Combined, the bellows and anti-clogging design optimize the stability and long-term performance of the air intake system.

[0003] Corrugated pipes play an indispensable role in automotive duct systems, making anti-clogging of corrugated pipes particularly important. Existing anti-clogging components mostly use filters for interception, but since they are usually installed inside, disassembly and installation are inconvenient, and the pipes themselves are also difficult to disassemble and clean.

Figure 3 This is a schematic diagram of the connecting component structure of the automotive bellows with anti-clogging function according to this utility model. The automotive bellows with anti-clogging function includes: a main body 1, two connecting pipes 2 are fixedly installed at both ends of the main body 1, and two anti-clogging components with the same structure but facing opposite directions are respectively provided in the two connecting pipes 2. The anti-clogging component includes an annular plate 3 fixedly installed on the inner wall of the connecting pipe 2, multiple support plates 4 are fixedly installed at the bottom of the annular plate 3, one side of each of the multiple support plates 4 is fixedly connected to the inner wall of the connecting pipe 2, and multiple arc-shaped locking blocks 5 are fixedly installed at the top of the annular plate 3. The anti-blocking component also includes an annular block 6 slidably installed in the connecting pipe 2. The outer wall of the annular block 6 is provided with a plurality of arc-shaped slots, which are adapted to a plurality of arc-shaped blocks 5. A plurality of arc-shaped sliders 7 are slidably installed in the plurality of arc-shaped slots. The bottom of the plurality of arc-shaped sliders 7 is provided with a guide slope. A plurality of arc-shaped mounting holes are provided on one side of the plurality of arc-shaped sliders 7. A plurality of arc-shaped spring telescopic rods 8 are fixedly installed in the plurality of arc-shaped mounting holes. The output ends of the plurality of arc-shaped spring telescopic rods 8 are fixedly connected to the inner wall of the plurality of arc-shaped slots. The anti-clogging component also includes a filter cartridge 9 fixedly installed at the bottom of the annular block 6.

[0017] Through the cooperation of the arc-shaped locking block 5, the arc-shaped locking groove 1, and the arc-shaped slider 7, a quick-replaceable filter screen is used to intercept and prevent clogging, ensuring the anti-clogging effect while making it easy to remove the filter screen for cleaning.

[0018] The other ends of the two connecting pipes 2 are respectively provided with two external pipes 10. The two connecting pipes 2 and the two external pipes 10 are respectively provided with two quick-connect assemblies with the same structure. The quick-connect assembly includes a collar 11 fixedly sleeved on the connecting pipe 2. An annular insert plate 12 is fixedly installed on the connecting pipe 2. An annular slot adapted to the annular insert plate 12 is opened on the external pipe 10. Multiple arc-shaped locking blocks 13 are fixedly installed on the collar 11. The quick-connect assembly also includes a collar 14 fixedly sleeved on the outer tube 10. The collar 14 has multiple arc-shaped slots 13 that are adapted to multiple arc-shaped blocks 13. The inner walls of the arc-shaped slots 13 have multiple sliding grooves. Multiple sliders 16 are slidably installed in the sliding grooves. Multiple mounting holes are provided on one side of the sliders 16. Multiple spring telescopic rods 15 are fixedly installed in the mounting holes. The other ends of the spring telescopic rods 15 are fixedly connected to the inner walls of the sliding grooves. Multiple sliding holes are provided on the inner walls of the sliding grooves. Multiple connecting blocks 17 are slidably installed in the sliding holes. One end of the connecting blocks 17 is fixedly connected to the sliders 16. The other ends of the connecting blocks 17 extend out of the sliding grooves and are fixedly installed with the same ring 18.

[0019] The coordinated operation of the arc-shaped locking block 13, the arc-shaped slot 2, the slider 16, the connecting block 17, and the ring 18 allows for quick disassembly and maintenance of the pipeline while ensuring the overall sealing effect of the pipeline.

[0020] The working principle of the automotive bellows with anti-clogging function provided by this utility model is as follows: First step: When using, depending on the actual needs, choose whether to install anti-clogging components at both ends of the corrugated pipe. When installing the anti-clogging components, insert the annular block 6 together with the filter cartridge 9 into the corresponding connecting pipe 2. Rotate the annular block 6 until the arc-shaped slot 1 and the arc-shaped block 5 are aligned. Then press the annular block 6 down. Multiple arc-shaped sliders 7 are squeezed and move to one side to avoid the pressure under the action of multiple arc-shaped spring telescopic rods 8. After multiple arc-shaped blocks 5 are fully inserted into multiple arc-shaped slots 1, rotate the annular block 6 again so that multiple arc-shaped blocks 15 are inserted deeper into the arc-shaped slots 1. At the same time, multiple arc-shaped sliders 7 are released from the pressure and reset under the action of multiple arc-shaped spring telescopic rods 8, preventing multiple arc-shaped blocks 15 from easily returning to their original path and becoming loose. When disassembling, rotate the annular block 6 in the opposite direction to apply pressure to multiple arc-shaped sliders 7 and lift it up to remove it. Second step: When installing the corrugated pipe and the outer pipe 10, insert the annular insert plate 12 into the annular slot facing each other. At the same time, insert multiple arc-shaped locking blocks 13 into multiple arc-shaped slots. During insertion, multiple sliders 16 are compressed back into the slots. After full insertion, slightly rotate the multiple arc-shaped locking blocks 13 to make them fully fit with the multiple arc-shaped slots. At this time, the multiple sliders 16 lose pressure and reset under the action of multiple spring telescopic rods 15 to prevent the multiple arc-shaped locking blocks 13 from disengaging, thus completing the installation.

[0021] Please refer to the following: Figures 4 to 5 ,in, Figure 4 This is a three-dimensional structural diagram of the flame-retardant corrugated pipe of this utility model; Figure 5 This is a structurally disassembled schematic diagram of the flame-retardant corrugated pipe of this utility model. The flame-retardant corrugated pipe includes: a pipe body 19, with two metal flame-retardant rings 20 fixedly installed at each end of the pipe body 19, and two annular connectors 21 fixedly installed at the other ends of the two metal flame-retardant rings 20.

[0022] By combining the tube body 19 and the metal flame-retardant ring 20, and using non-combustible material as an intermediate transition section, the flame retardancy of the corrugated pipe is achieved.

[0023] The working principle of the flame-retardant corrugated pipe provided by this utility model is as follows: The first step: The flame retardancy of the corrugated pipe is achieved by using the isolation effect of the non-combustible metal ring.
