[0002] The engine air intake passage is the channel for air to enter and exit the air cleaner, the air intake pipe is the pipe connecting the air cleaner to the carburetor, and the pipe connecting to the cylinder intake valve.

[0003] At present, the air intake pipe refers to the section of pipeline through which air enters from the air inlet, passes through the air cleaner, and then enters each cylinder, which is the main engine intake pipeline and the total air intake pipeline.

[0004] However, the traditional air intake pipe often sucks in a large amount of dust, impurities and other particulate matters during operation, which not only affects the air intake efficiency of the engine, but also may cause damage to the internal components of the engine, and even cause failure in severe cases, affecting the normal operation and service life of the automobile.

[0005] To solve this technical problem, the prior art with application number "CN202020464682.2" named "Automobile engine air intake pipe" proposes an air intake pipe with particle filtration function, which comprises an air intake pipe and a protection device, the protection device comprises a first fixed pipe, a second fixed pipe, a circular connecting plate and a filter screen, the second fixed pipe extends into the inside of the first fixed pipe, the distance between the side wall of the first fixed pipe and the side wall of the second fixed pipe matches the thickness of the wall of the air intake pipe, the outer diameter of the circular connecting plate is consistent with the outer diameter length of the first fixed pipe, the inner diameter of the circular connecting plate is consistent with the inner diameter length of the second fixed pipe, and the rear wall of the circular connecting plate is fixedly connected with the front wall of the second fixed pipe and the second fixed pipe, the centers of the first fixed pipe, the second fixed pipe and the circular connecting plate are located at the same position, the filter screen is circular in shape and has a diameter consistent with the outer diameter length of the second fixed pipe, and the filter screen is fixedly connected with the rear wall of the second fixed pipe.

[0024] The application also relates to an automobile provided with the high-protection automobile engine air inlet pipe.

[0025] The application has the following advantages: 1. The application relates to a high-protection automobile engine air inlet pipe. The air inlet pipe has an automatic cleaning function. The cooperation of the scraper and the driving structure realizes automatic dust scraping on the inner wall of the air inlet pipe. External cleaning equipment is not needed, manual maintenance cost is reduced, dust accumulation is prevented, and the engine air inlet efficiency and performance are not affected. The mounting groove and the air outlet pipe of the dust collection structure are designed to effectively collect and discharge the scraped dust, prevent the dust from re-entering the airflow, keep the air inlet pipe clean, and prolong the service life of the engine. The stop valve closes the air inlet pipe outlet during cleaning, isolates the engine from the cleaning process, prevents the dust from entering the engine combustion chamber, and improves the cleaning safety and engine protection. The design integrates the cleaning and protection functions. Regular automatic cleaning reduces the risk of air inlet pipe blockage and corrosion, is suitable for harsh environments, and improves the durability and reliability of the air inlet pipe. 2. A plurality of connecting rods are arranged on the inner wall of the air inlet pipe body. The connecting rods provide accurate axial guidance for the scraper, ensure that the scraper always closely adheres to the inner wall of the air inlet pipe during movement, improve the uniformity and efficiency of cleaning, and prevent the scraper from being skewed or stuck. The fixed mode of the connecting rod and the mounting seat is compact, easy to manufacture and assemble, and reduces the production cost and maintenance difficulty. The circumferential interval arrangement of the connecting rod improves the stability of the overall structure, is suitable for high-speed airflow environments, and reduces vibration and wear. 3. A plurality of mounting seats are arranged on the inner wall of the air inlet pipe body. The grouping design of the mounting seats limits the movement range of the scraper, ensures that the scraper moves in the effective cleaning area, avoids excessive movement or disengagement, and improves the targeting and reliability of cleaning. The layout between adjacent mounting seats maximizes the use of the internal space of the air inlet pipe, reasonably arranges the movement path of the scraper, does not interfere with the normal flow of the airflow, and maintains the air inlet efficiency of the engine. The circumferentially spaced mounting seats evenly distribute the stress on the scraper, reduce local wear, and prolong the service life of the scraper and the air inlet pipe. 4. The drive structure of this application includes a baffle, which directly uses the intake gas pressure of the intake pipe to drive the scraper, eliminating the need for an external power source, saving energy and protecting the environment, and reducing system complexity and cost; when the engine is running, the intake airflow automatically pushes the baffle, realizing the axial movement of the scraper, achieving automated cleaning "as needed", and improving response speed; the connection between the baffle and the scraper is direct and effective, reducing moving parts, lowering the failure rate, and making it suitable for long-term use; 5. This application provides a conical groove on the baffle. The conical groove structure guides the airflow to concentrate, improves gas flow efficiency, reduces pressure loss, and increases the thrust on the baffle, thereby enhancing the driving capability of the scraper. The conical design reduces turbulence and resistance when the airflow passes through the baffle, which helps maintain stable engine intake pressure and improves engine performance. The conical groove may promote the cleaning of the baffle surface by the airflow and prevent dust from accumulating on the drive structure. 6. This application also provides multiple conical holes on the baffle. These multiple conical holes allow the airflow to pass through the baffle evenly, avoiding single-point pressure concentration, improving the force balance of the baffle, and ensuring smooth movement of the scraper. The conical holes increase the gas passage area, enhance the thrust output, and make the scraper move faster and the cleaning efficiency higher. The evenly distributed holes in the circumference reduce the weight of the baffle while ensuring structural strength, reducing the effect of inertia and facilitating rapid response. 7. The baffles on adjacent scrapers in this application do not overlap in the axial direction of the air intake pipe body. The non-overlapping baffle design ensures that each scraper does not interfere with each other when moving axially, improving the reliability of multiple scrapers working together. Each scraper responds independently to the airflow, realizing segmented cleaning and improving the comprehensiveness and efficiency of cleaning. 8. This application also includes a reset structure for driving the scraper to move axially along the intake pipe body to the initial position; the reset structure ensures that the scraper automatically returns to the initial position after cleaning, preparing for the next cleaning cycle, improving the automation level and continuous working capability of the system; there is no need to manually adjust the scraper position, reducing maintenance time and ensuring the timeliness and consistency of cleaning operations; it avoids the scraper from staying in a non-initial position for a long time, reducing structural stress and wear. 9. The reset structure of this application includes a reset spring that passes through the connecting rod. The spring structure uses elastic force to achieve reset, which is low in cost and durable, requires no additional control device, and reduces system complexity. The spring is installed on the connecting rod to provide uniform reset force, ensuring accurate return of the scraper and avoiding positional deviation. The spring fits tightly with the existing structure (connecting rod and mounting base), making installation and replacement convenient and reducing maintenance costs. 10. This application includes a filter screen installed in the mounting slot. The filter screen can capture fine dust that may escape after being scraped, improving cleanliness and further protecting the engine from dust damage. As a barrier, the filter screen ensures that the collected dust is effectively isolated and will not re-enter the intake manifold under the action of airflow, thus enhancing the dust collection effect. The additional filter layer improves the protection level of the intake manifold, making it suitable for high-dust environments and extending the engine maintenance cycle. 11. This application provides a cleaning brush on the outer circumferential end face of the scraper. The cleaning brush can more thoroughly remove stubborn dust adhering to the inner wall, improving the thoroughness of cleaning, and is especially suitable for oily or dusty environments. The brush material can adapt to the irregular surface of the inner wall of the air intake pipe, reducing the risk of scratching, while providing a gentler cleaning method. Compared with a hard scraper, the cleaning brush may reduce friction noise and wear with the inner wall, improving the comfort and lifespan of the air intake pipe. 12. This application provides a protective structure on the outside of the intake pipe body to absorb external impacts. The protective structure effectively absorbs and disperses external physical impacts (such as vibration and collision), protects the intake pipe from damage, and improves its durability under harsh road conditions. Through damping or elastic elements, it reduces the vibration transmitted from the intake pipe to the engine, improving the overall NVH (noise, vibration, and ride comfort) performance of the vehicle. The protective structure reduces the risk of intake pipe breakage or deformation, ensures the stability of engine intake, and improves vehicle safety. 13. The protective structure of this application includes a mounting bracket, a clamping bracket, and multiple damping springs. The damping springs provide multi-directional buffering and effectively absorb impact energy. At the same time, the clamp-type mounting bracket ensures that the structure is firmly fixed and prevents loosening. The circumferentially spaced springs distribute the impact force evenly, avoid local stress concentration, and improve the comprehensiveness and reliability of the protection. The spring structure allows the intake pipe to deform slightly under temperature changes, reducing thermal stress damage and making it suitable for the high-temperature environment of automotive engines. 14. The multiple sets of protective structures in this application are arranged at intervals along the axial direction of the intake pipe body and connected into one unit by a connecting structure. After the multiple sets of structures are connected, they form a continuous protective layer that covers the entire length of the intake pipe, providing more comprehensive protection and preventing local weaknesses. The connecting structure enables multiple protective units to work together, improving the overall rigidity and stability, and is suitable for long intake pipe designs. The axially spaced arrangement allows for flexible adjustment of the number of protective sets according to the length of the intake pipe, making it easy to customize and install, and reducing production costs. 15. The connection structure of this application includes a connecting frame that connects adjacent protective structures by bolts; the groove design allows for fine adjustment of the axial position to accommodate manufacturing tolerances or installation errors of the intake pipe, improving assembly flexibility; bolt fixing provides a reliable mechanical connection, ensuring that the protective structure does not loosen under vibration, enhancing long-term reliability; the bolt connection method makes the protective structure easy to disassemble for cleaning or replacement, reducing maintenance time and costs; 16. This application also relates to a dust removal method with clear and specific steps, ensuring the standardization and repeatability of cleaning operations, and improving cleaning efficiency and effectiveness; this application utilizes the air intake pipe itself to drive the scraper, eliminating the need for external energy, achieving low-cost automated cleaning, and reducing manual intervention; through the cooperation of scraper movement and dust collection structure, dust on the inner wall is thoroughly removed, avoiding engine problems caused by dust accumulation, and extending the life of the intake pipe and engine; 17. This application also relates to an automobile equipped with the above-mentioned intake pipe. The automobile using the intake pipe can keep the intake air clean, improve the combustion efficiency and power output of the engine, and reduce the failure rate; the automatic cleaning function reduces the need for regular maintenance of the intake pipe and lowers the overall operating cost of the automobile; the high protective design makes the automobile more suitable for operation in dusty or harsh environments, improving reliability and user satisfaction.

[0026] The automotive engine intake pipe of this application has the advantages of high protection, high cleaning efficiency, reliable structure and high degree of automation. It solves the problem of dust accumulation in traditional intake pipes, and improves the performance and service life of the overall automotive engine system by integrating protection and cleaning functions.

Detailed Implementation

[0028] The embodiments of this application are described in detail below, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this application, and should not be construed as limiting this application.

[0029] In the description of this application, it should be understood that the terms "longitudinal", "lateral", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this application.

[0030] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this application, "multiple" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0031] The present application will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0032] This application provides a highly protective automotive engine intake pipe. The intake pipe of this application has a self-cleaning function, which can automatically clean the inner wall of the engine intake pipe, solving the problem of easy dust accumulation in traditional intake pipes. Furthermore, by integrating protection and cleaning functions, it improves the performance and service life of the overall automotive engine system.

[0033] Specifically, such as Figures 1 to 5 As shown, this application includes an intake pipe body 1, which is a hollow tubular structure with openings at both ends. Connectors are fixedly installed at both ends of the intake pipe body 1. Mounting plates are provided on the outside of the connectors, and threaded holes are provided inside the mounting plates to facilitate the connection of the intake pipe body 1 with other structures. The two ends of the intake pipe body 1 are connected to other functional components, such as filters or cylinders, through the connectors. When in use, they can be installed with bolts and threaded holes.

[0034] Inside the intake pipe body 1, multiple annular scrapers 2 are arranged at intervals along its axial direction, with the outer circumference of the scrapers 2 tightly fitted against the inner wall of the intake pipe body 1. A drive structure is also provided inside the intake pipe body 1, connected to the scrapers 2, for driving the scrapers 2 to move axially along the intake pipe body 1. Near the outlet of the intake pipe body 1, a dust collection structure is provided, including a mounting groove 3 installed on the pipe wall. One side of the mounting groove 3 communicates with the interior of the intake pipe body 1 (the intake pipe body 1 has a through hole through which the mounting groove 3 communicates with the intake pipe body 1), and the other side is connected to an outlet pipe 4. Furthermore, a shut-off valve 5 is installed in the pipe section between the mounting groove 3 and the outlet of the intake pipe body 1.

[0035] When it is necessary to clean the dust adhering to the inner wall of the intake pipe body 1, the control system first closes the shut-off valve 5, cutting off the connection between the intake pipe and the engine. Then, air is supplied to the intake pipe body 1 through an external air source. The airflow acts on the drive structure, which converts the energy of the airflow into mechanical thrust, pushing multiple scrapers 2 to move axially sequentially or synchronously. During the movement, the edges of the scrapers 2 scrape off the dust from the inner wall of the intake pipe body 1. The scraped dust, carried by the airflow, enters the mounting groove 3 and is temporarily stored there, eventually being centrally cleaned through the exhaust pipe 4. After cleaning, the shut-off valve 5 is opened, and the intake pipe resumes normal operation.

[0036] During normal use, when there is airflow inside the intake pipe body 1, the scraper 2 can move axially under the drive of the drive structure, thereby scraping the inner wall of the intake pipe body 1 to prevent dust in the gas from adhering to the inner wall of the intake pipe body 1.

[0037] The intake manifold of this application features online, automatic, and closed-loop cleaning capabilities. Through the coordinated action of the scraper 2, drive structure, dust collection structure, and shut-off valve 5, the inner wall can be cleaned without disassembling the intake manifold body 1, significantly reducing maintenance costs and time. The shut-off valve 5 ensures that dust does not enter the engine during cleaning, guaranteeing engine safety. The entire system is compact, fully functional, and significantly improves the protection and service life of the intake manifold.

[0038] In some embodiments of this application, the scraper 2 mounting structure described above has been optimized, specifically, as follows: Figure 1 As shown, multiple sets of mounting seats 7 are fixed on the inner wall of the intake pipe body 1. Multiple connecting rods 6 are arranged at intervals along the circumference of the intake pipe body 1. Each connecting rod 6 passes through all the scrapers 2, and the two ends of the connecting rod 6 are respectively fixed to two axially corresponding mounting seats 7. The scraper 2 is provided with through holes, so that it can be slidably sleeved on the connecting rod 6.

[0039] The connecting rod 6 and the mounting base 7 together form a rigid guide frame. When the drive structure pushes the scraper 2 to move, the scraper 2 slides along the connecting rod 6. The connecting rod 6 plays a guiding and supporting role, ensuring that the scraper 2 always remains perpendicular and in contact with the inner wall of the intake pipe body 1 during the movement, without deflection or jamming.

[0040] This embodiment, through the connecting rod 6 structure, greatly improves the stability and reliability of the scraper 2's movement. The connecting rod 6 prevents the scraper 2 from rotating or shaking under airflow impact, ensuring the uniformity and thoroughness of the dust removal effect. At the same time, this structure has high strength, is not easily deformed, and extends the overall lifespan of the cleaning system.

[0041] In a further embodiment of this application, the scraper 2 mounting structure described above has been optimized, specifically, as follows: Figure 1 As shown, the mounting seats 7 are arranged in "groups", each group containing multiple mounting seats 7 spaced apart circumferentially. The multiple groups of mounting seats 7 are arranged at intervals along the axial direction of the intake pipe body 1. Each connecting rod 6 passes through multiple mounting seats 7 that overlap in the axial direction. Each scraper 2 is disposed between two adjacent groups of mounting seats 7.

[0042] Two adjacent sets of mounting seats 7 define an axial travel limit range for a scraper 2. Under the action of the drive structure, the scraper 2 can move back and forth within this defined range. The mounting seat 7 itself is not only used to fix the connecting rod 6, but its sidewall can also serve as a mechanical limit block for the movement of the scraper 2.

[0043] This embodiment precisely controls the movement range of the scraper 2. On the one hand, it avoids excessive movement of the scraper 2 and interference with other components; on the other hand, it ensures that the inner wall of each section of the intake pipe body 1 can be effectively scraped, without any dead corners. This modular layout makes the design of the intake pipe more reasonable and facilitates production and assembly.

[0044] In other embodiments of this application, the driving structure described above has been optimized, specifically, as follows: Figure 1 and 2 As shown, the drive structure of this embodiment includes a baffle 8. One end of the baffle 8 is fixed to the inner circumference of the scraper 2 by one or more connecting posts, and the other end extends radially inward toward the scraper 2. The surface of the baffle 8 is perpendicular to the axial direction of the intake pipe body 1.

[0045] The kinetic energy of the gas inside the intake pipe body 1 is converted into mechanical energy by the baffle 8. When the airflow enters the intake pipe body 1, it impacts the vertical plate surface of the baffle 8. Since the baffle 8 is fixed, the airflow generates a continuous pressure on the baffle 8. This pressure is transmitted to the scraper 2 through the connecting column and is converted into a thrust that pushes the scraper 2 to move axially.

[0046] In this embodiment, the baffle 8 directly utilizes the air intake pipe itself as a power source, eliminating the need for an additional motor or hydraulic device, thus achieving zero-energy, self-driven cleaning. It features a simple structure, low cost, and extremely high reliability, virtually eliminating any potential points of failure in the system.

[0047] In a preferred embodiment of this application, the structure of the baffle 8 described above has been optimized, specifically, as follows: Figure 2 As shown, a conical groove 9 is provided in the center of the baffle 8 in this embodiment. The conical groove 9 is a hollow conical cylindrical structure with open ends. Its axis is parallel to the axis of the intake pipe body 1, and the end with the larger cross-sectional area (large end) faces the inlet side of the intake pipe body 1.

[0048] The conical groove 9 serves to guide and accelerate airflow. According to Bernoulli's principle, as airflow passes through the gradually narrowing conical channel, its velocity increases, creating a localized low-pressure zone behind the smaller end of the conical groove 9. This not only reduces the overall wind resistance of the baffle 8, minimizing its impact on intake efficiency, but also enhances the airflow's driving efficiency on the scraper 2.

[0049] This embodiment optimizes intake performance while achieving the driving function. The conical groove 9 effectively reduces the negative impact of the drive structure on engine intake resistance, ensuring engine power.

[0050] In a further embodiment of this application, the above-mentioned baffle 8 structure has been further optimized, specifically, as follows: Figure 2 As shown, in this embodiment, multiple conical holes 10 are also formed on the baffle 8. These conical holes 10 are conical holes 10 that penetrate the baffle 8, and their larger ends also face the inlet side of the intake pipe body 1. The multiple conical holes 10 are evenly distributed circumferentially with the central conical groove 9 as the center.

[0051] Multiple conical holes 10 form an auxiliary airflow channel. The conical holes 10 allow some airflow to pass through the baffle 8 with less resistance, further balancing the pressure difference before and after the baffle 8 and significantly reducing pressure loss. At the same time, the evenly distributed conical holes 10 ensure that the thrust acting on the baffle 8 is uniform, avoiding unilateral force.

[0052] This embodiment further enhances the effects of reducing drag and balancing force. The tapered orifice 10 makes the flow field of the intake pipe body 1 more stable, minimizing the impact on engine intake efficiency. At the same time, the uniform force makes the scraper 2 move more smoothly, reducing structural vibration and wear.

[0053] In some embodiments of this application, the scraper 2 structure described above has been further optimized. Specifically, as follows: Figure 1 As shown in the figure, in this embodiment, the baffles 8 connected to two adjacent scrapers 2 do not overlap in the axial direction along the axial direction.

[0054] The staggered arrangement of the baffles 8 ensures that the airflow acts on each baffle 8 without obstruction and sequentially. If the baffles 8 overlap, the upstream baffle 8 will block the downstream baffle 8, affecting the driving effect of the downstream scraper 2.

[0055] The arrangement of baffles 8 in this embodiment ensures the independence and efficiency of multiple drive units. Each scraper 2 can obtain sufficient airflow drive, realizing coordinated and efficient segmented cleaning, and ensuring that the entire inner wall of the intake pipe body 1 can be thoroughly cleaned.

[0056] In some other embodiments of this application, a reset structure is added to the above structure. This reset structure is disposed on the scraper 2 and is used to drive the scraper 2 back to its initial position after ventilation is completed. Specifically, as shown... Figure 1 As shown, the reset structure includes a reset spring 11. The reset spring 11 is directly sleeved on the connecting rod 6. The two axial ends of the spring are respectively fixed to two mounting seats 7 representing the stroke range of the scraper 2. The scraper 2 is fixed to the reset spring 11 by means of snap-fit ​​or welding.

[0057] The reset structure provides a force opposite to the driving direction. Its control method is integrated with the driving process: when the cleaning process ends and the air supply is stopped (or the driving air source is turned off), the driving thrust disappears. At this time, the reset structure starts working, automatically pushing or pulling the scraper 2 back to its initial position, preparing for the next cleaning cycle.

[0058] When the drive mechanism pushes the scraper 2 to compress the spring on one side, the spring stores elastic potential energy. When the driving force disappears, the compressed spring releases its potential energy, pushing the scraper 2 to move in the opposite direction until it returns to its initial equilibrium position.

[0059] The reset structure enables the scraper 2 to automatically return to its original position, making the entire system a complete, cyclical, automated system. No manual intervention is required for reset, greatly improving ease of use and automation. The reset spring 11 has a simple structure, reliable operation, long lifespan, and requires no external control. The design of fixing the scraper 2 to the middle of the spring cleverly utilizes the spring's bidirectional elasticity to achieve stable reciprocating motion.

[0060] In some embodiments of this application, the dust collection structure described above has been further optimized, specifically, as follows: Figure 3 As shown, in this embodiment, a filter screen 12 is installed inside the mounting slot 3.

[0061] The filter screen 12 acts as a filtration barrier. When the airflow carrying the scraped dust enters the mounting slot 3, the flow rate decreases, and the filter screen 12 can intercept most of the dust and collect it inside the filter screen 12. For subsequent cleaning, it is only necessary to remove the filter screen 12 from the mounting slot 3 for cleaning.

[0062] The filter 12 structure in this embodiment greatly improves dust collection efficiency and cleanliness. Filter 12 ensures that dust can be collected efficiently, achieving more thorough cleaning and providing a higher level of air purification protection for the engine.

[0063] In other embodiments of this application, the dust collection structure described above has been further optimized, specifically, as follows: Figure 1 and 2As shown, in this embodiment, a cleaning brush 13 made of flexible material (such as nylon or rubber) is embedded or bound to the outer circumferential end face of the scraper 2.

[0064] The cleaning brush 13 provides a gentler and deeper cleaning. Compared to the hard scraper 2, the bristles can better adapt to the minor unevenness that may exist on the inner wall of the intake manifold body 1, and can effectively remove stickier dirt.

[0065] The cleaning brush 13 provides a more thorough cleaning while protecting the inner wall. The flexible bristles reduce the potential abrasion to the pipe wall caused by hard scraping, while removing adhering substances that are difficult to handle by the hard scraper 2, thus expanding the applicable conditions of this cleaning system.

[0066] In some embodiments of this application, an external protective structure is also provided, such as... Figure 4 and 5 As shown, in this embodiment, one or more protective structures for absorbing external impacts are fitted on the outside of the intake pipe body 1. The protective structure includes a clamp-type mounting bracket 14 fitted on the outside of the intake pipe body 1, a clamping bracket 15 tightly fitted to the outer wall of the intake pipe body 1, and a plurality of circumferentially arranged damping springs 16 connecting the mounting bracket 14 and the clamping bracket 15.

[0067] The protective structure in this embodiment acts as a buffer energy-absorbing layer. When the intake pipe body 1 is subjected to mechanical impact, the impact force is first transmitted to the damping spring 16 through the mounting bracket 14. The damping spring 16 absorbs and dissipates energy through compression and rebound. The clamping bracket 15 ensures flexible contact with the intake pipe body 1 to avoid scratches.

[0068] The protective structure of this embodiment provides excellent cushioning and shock absorption performance. The damping spring 16 can effectively attenuate vibrations and impacts of various frequencies, which not only protects the intake manifold body 1, but also indirectly improves the lifespan of the engine components connected to it.

[0069] In a further embodiment of this application, the dustproof structure described above has been further optimized, specifically, as follows: Figure 4 and 5 As shown, multiple sets of protective structures as described in the embodiment are arranged at intervals along the axial direction of the intake pipe body 1. Furthermore, adjacent protective structures are axially connected as a single unit via a connecting structure. The connecting structure includes a connecting bracket 17 fixed to the mounting bracket 14, and the connecting bracket 17 has an axially elongated sliding groove. The connecting brackets 17 of two adjacent protective structures are connected and locked by bolts passing through the sliding groove.

[0070] Multiple interconnected protective structures form a continuous, integrated protective framework. This ensures that the protective effect covers the entire length of the intake pipe body 1, and each unit can work together to resist and transfer loads, enhancing overall rigidity.

[0071] The groove on the connecting bracket 17 provides axial position adjustment. During installation, the spacing of each set of protective structures can be finely adjusted according to the actual length of the intake pipe body 1 and the installation point position, and finally locked and fixed with bolts.

[0072] This protective structure greatly facilitates the installation of the intake pipe body 1, adapts to different vehicle models and sizes of intake pipe bodies 1, has strong versatility, and reduces the requirements for manufacturing and assembly precision.

[0073] When dust removal is required on the intake manifold body 1, this application closes the shut-off valve 5 via the vehicle ECU or manual control, blocking the outlet of the intake manifold body 1; an external air source is connected to allow air to flow into the intake manifold body 1, and the airflow acts on the baffle 8; the baffle 8 pushes the scraper 2 to move axially, and during the movement, the scraper 2 scrapes off the dust on the inner wall of the intake manifold body 1 that is attached to its outer circumference; the scraped dust is carried by the airflow into the mounting groove 3 and collected in the filter screen 12; after the dust on the inner wall of the intake manifold body 1 has been completely scraped off (which can be determined by a preset airflow time), the airflow is stopped, the shut-off valve 5 is opened, and the normal function of the intake manifold is restored. Then, periodically or as needed, the filter screen 12 in the mounting groove 3 is removed for cleaning, completing the entire dust removal operation.

[0074] This application also relates to a vehicle equipped with the aforementioned air intake pipe.

[0075] like Figure 1 As shown, the axial direction of this application Figure 1 The axial direction of the scraper in this application, the circumferential direction. Figure 1 In the circumferential direction centered on the scraper's center, the radial direction of this application refers to... Figure 1 The radial direction centered on the center of the scraper.

Those skilled in the art should understand that this application is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this application. Various changes and modifications can be made to this application without departing from the spirit and scope thereof, and all such changes and modifications fall within the scope of this application as claimed.
