Description

Technical Field

[0001] This application relates to the technical field of air intake, and more particularly to an air intake pipe, an air intake assembly, and a vehicle. Background Technology

[0002] The vehicle's air filter traps dust and impurities in the air to prevent wear and tear on internal engine components caused by dust intrusion, thus ensuring the engine's normal operation. The air intake function of the air filter relies on the intake manifold; outside air must flow through the intake manifold before entering the filter element for filtration, and then be delivered to the engine's combustion chamber through subsequent pipelines.

[0003] Most existing air intake pipes are made of a single non-metallic material. When air flows inside the pipe, friction with the pipe wall easily generates static electricity. The charged pipe wall actively attracts fine particulate matter suspended in the air. These attracted particles gradually accumulate on the pipe wall surface, forming a dense dust cake layer. This reduces the cross-sectional area of ​​the airflow channel, thereby increasing the air filter's intake resistance. Consequently, a rated energy is required to maintain normal air intake. Furthermore, long-term use will reduce the lifespan of the air intake pipe. Utility Model Content

[0004] This application addresses, to at least some extent, one of the technical problems in the related art.

[0005] Therefore, this application aims to provide an intake pipe, intake assembly, and vehicle, by providing a conductive layer on the outer wall of the inner pipe. Static electricity generated by friction between the inner pipe and the air is captured by the intermediate conductive layer and conducted to the vehicle body or engine through a grounding wire. Since the vehicle body and engine are made of metal and are both grounded, the current can be discharged, thereby eliminating the problem of electrostatic adsorption of fine particulate matter on the inner pipe wall.

[0006] To achieve the above objectives, in a first aspect, this application provides an intake pipe, comprising: A pipe body for communicating with the air inlet of an air filter; the pipe body includes: Inner tube; A conductive layer that covers the inner tube; The outer tube is fitted with the conductive layer; A grounding wire, one end of which is electrically connected to the conductive layer, and the other end of which is used to conduct electricity.

[0007] In this technical solution, the inner tube serves as the airflow contact surface, ensuring a stable airflow. Static electricity generated by friction between the inner tube and the air is captured by the intermediate conductive layer and conducted to the vehicle body or engine via a grounding wire. Because the vehicle body and engine are made of metal and are grounded, the current can be discharged, thus eliminating the problem of fine particulate matter adsorbing due to electrostatic discharge on the inner tube wall. The outer tube is wrapped with a conductive layer and protected to prevent the conductive layer from failing due to wear or impact from the external environment. This continuously eliminates the electrostatic potential energy on the intake pipe wall, preventing fine particles from being forcibly adsorbed by electrostatic force, allowing the filter element surface to accumulate evenly according to natural filtration principles, and maintaining the effective cross-sectional area of ​​the airflow channel.

[0008] In some embodiments of this application, a metal clamp is further included for connecting the tube body to the air inlet of the air filter; the metal clamp is in contact with the conductive layer; The grounding wire contacts and connects to the metal clamp.

[0009] In this technical solution, the metal clamp serves two main functions: firstly, it secures the pipe body to the air filter inlet, enhancing the seal and structural stability of the connection and preventing airflow leakage from gaps, thus reducing air intake loss. Secondly, the metal clamp is in direct contact with the conductive layer, allowing static electricity to be transferred from the conductive layer through the clamp to the grounding wire. This design facilitates connection between the grounding wire and the metal clamp. Compared to connecting the grounding wire directly to the conductive layer, even if the grounding wire breaks, a new grounding wire can be quickly connected to the metal clamp, simplifying maintenance.

[0010] In some embodiments of this application, the conductive layer has a bent section folded outward at one end near the metal clamp; the bent section passes through the outer tube, or the bent section is located at one end of the outer tube, and the bent section is in contact with the metal clamp.

[0011] In this technical solution, regardless of whether the bend passes through the outer tube or the end of the outer tube is located on one side of the bend, the conductive layer can form direct physical contact with the metal clamp. This avoids problems such as excessive conductive resistance or disconnection caused by an insufficient contact area between the conductive layer and the metal clamp, thus improving electrostatic conduction efficiency. Furthermore, the end of the outer tube can abut against the bend, limiting the relative position of the outer tube and the conductive layer. This prevents displacement of the conductive layer or the outer tube due to vibration during vehicle movement, ensuring long-term stable contact between the conductive layer and the metal clamp.

[0012] In some embodiments of this application, the end of the bent section is further bent into a contact section, the outer peripheral wall of the contact section is flush with the outer peripheral wall of the outer tube, and the metal clamp is fitted onto and contacts the contact section.

[0013] In this technical solution, the contact area with the metal clamp is increased by the contact section, further improving conductivity stability. This avoids excessive resistance caused by poor contact or an insufficient contact area. It also addresses instability issues, ensuring that static electricity can be fully transferred to the metal clamp through the contact section, improving the uniformity and efficiency of static electricity conduction. The design of the contact section being flush with the outer circumference of the outer tube allows the metal clamp to simultaneously fit the outer tube and the contact section during installation, enhancing the locking effect of the metal clamp on the tube body. This strengthens the connection and seal between the tube body and the air filter inlet, and avoids localized stress concentration caused by uneven contact surfaces of the metal clamp, reducing the risk of fatigue damage to the tube body or the metal clamp.

[0014] In some embodiments of this application, the outer peripheral wall of the inner tube has an annular receiving cavity, and both the conductive layer and the outer tube are located within the receiving cavity.

[0015] In this technical solution, the receiving cavity limits the position of the conductive layer and the outer tube, with both ends of the conductive layer and the outer tube abutting against the two inner walls of the receiving cavity. This prevents the conductive layer or outer tube from shifting due to vibration during vehicle movement, ensuring that the conductive layer remains in the preset position between the inner and outer tubes and guaranteeing stable contact between the conductive layer and the metal clamp. Simultaneously, it prevents the conductive layer from being exposed and thus avoiding damage or failure.

[0016] In some embodiments of this application, a retaining ring is provided on the outer peripheral wall of the inner tube end, and the conductive layer and the end of the outer tube are used to abut against the retaining ring.

[0017] In this technical solution, the retaining ring directly abuts against the ends of the conductive layer and the outer tube, limiting their movement and preventing displacement due to vibration during vehicle operation. This ensures the conductive layer remains in its preset position between the inner and outer tubes, guaranteeing stable contact between the conductive layer and the metal clamp. Simultaneously, it prevents the conductive layer from being exposed and thus avoiding damage or failure.

[0018] In some embodiments of this application, the conductive layer is a metal mesh.

[0019] In this technical solution, the metal mesh possesses excellent conductivity, efficiently capturing and conducting static electricity generated by friction between the air and the inner tube. Compared to other conductive materials, the metal mesh has lower conductivity resistance and faster static electricity conduction speed, quickly eliminating electrostatic potential energy on the tube wall and preventing dust adsorption caused by the temporary accumulation of static electricity on the inner tube wall. Simultaneously, the metal mesh exhibits good structural toughness and strength, adapting to vibrations and temperature changes during vehicle operation, and is not prone to breakage or deformation. Its conductivity remains stable over long-term use, preventing the static electricity discharge function from failing due to damage to the conductive layer. Furthermore, the mesh structure of the metal mesh does not hinder the fit between the inner and outer tubes, nor does it create additional resistance to airflow within the tube. While ensuring the static electricity discharge function, it also considers the air intake efficiency and structural stability of the tube. Moreover, the cost of the metal mesh material is controllable, facilitating mass production and application.

[0020] In addition, this application also provides an air intake assembly, which includes an air filter, an air filter exhaust pipe and the above-mentioned air intake pipe, wherein the air intake pipe is connected and communicates with the air intake port of the air filter, and the air filter exhaust pipe is connected and communicates with the exhaust port of the air filter.

[0021] In the technical solution, the intake pipe has an electrostatic discharge function to ensure that dust in the airflow entering the air filter is not adsorbed by the pipe wall, thus avoiding the formation of a dense dust cake layer in the filter element due to electrostatic adsorption, extending the service life of the filter element, and reducing the frequency of filter element replacement and maintenance costs.

[0022] In some embodiments of this application, the air inlet of the air filter is connected to a connecting pipe, which is inserted into one end of the inner tube; the metal clamp is located on the outer periphery of the connecting pipe, and the metal clamp locks the tube body to the connecting pipe.

[0023] In this technical solution, the connecting pipe is connected to the inner pipe via a metal clamp, further optimizing the connection reliability and intake stability of the intake assembly. This ensures smooth airflow into the air filter. The metal clamp, while achieving the connection, also functions to conduct current from the conductive layer to the grounding wire.

[0024] In addition, this application also provides a vehicle comprising: a body, an engine, and the aforementioned intake assembly; the engine is disposed on the body, and the grounding wire in the intake assembly is electrically connected to the body or the engine.

[0025] In this technical solution, the vehicle's air intake pipe is electrically conductive, dissipating static electricity generated by the air inside and preventing dust from adhering to the inner wall of the pipe due to static electricity. This ensures sufficient air intake, extends the pipe's lifespan, and reduces energy consumption.

[0026] As can be seen from the above technical solutions, additional aspects and advantages of this application will be set forth in part in the description which follows, and in part will be obvious from the description, or may be learned by practice of this application.

[0030] The present application will now be described in detail through exemplary embodiments. However, it should be understood that, without further description, elements, structures, and features in one embodiment may be advantageously incorporated into other embodiments. It should be noted that in the automotive industry, a vehicle's air filter uses a filter element to trap dust and impurities in the air to prevent wear and tear on internal engine components caused by dust intrusion, thus ensuring the engine's normal operation. The air filter's intake function relies on the intake manifold; outside air must flow through the intake manifold before entering the filter element for filtration, and then be delivered to the engine's combustion chamber through subsequent piping.

[0031] In existing technologies, most air intake pipes are made of a single non-metallic material. When air flows inside the pipe, friction with the pipe wall easily generates static electricity. The charged pipe wall actively attracts fine particulate matter suspended in the air. These attracted particles gradually accumulate on the pipe wall surface, forming a dense dust cake layer. This reduces the cross-sectional area of ​​the airflow channel, thereby increasing the air filter's intake resistance. Consequently, a rated energy is required to maintain normal air intake. Furthermore, long-term use leads to a reduction in the lifespan of the air intake pipe.

[0032] Based on this, this application proposes an intake pipe, an intake assembly, and a vehicle. By providing a conductive layer outside the inner pipe and a grounding wire on the conductive layer, the static electricity generated by the friction between the inner pipe and the air is captured by the intermediate conductive layer and conducted to the vehicle body or engine through the grounding wire. Since the vehicle body and engine are made of metal and are both grounded, the current can be discharged, thereby eliminating the problem of electrostatic adsorption of fine particulate matter on the inner pipe wall.

[0033] In the following, embodiments of this application will be described in detail with reference to the accompanying drawings.

[0034] Referring to all the accompanying drawings, in one illustrative embodiment of the intake pipe, intake assembly, and vehicle described in this application, the intake pipe includes a pipe body for communicating with the air intake port of an air filter 600. Air enters the air filter 600 through the pipe body. The pipe body ensures efficient and low-resistance airflow to guarantee that the engine receives sufficient and clean air under various operating conditions, thereby improving engine combustion efficiency and performance, while reducing the risk of wear and malfunctions caused by dust and impurities entering the engine.

[0035] In some embodiments, the tube body includes an inner tube 100 through which air is directly connected to the air filter 600. The inner tube 100 serves as an airflow contact surface, ensuring the basic function of stable airflow.

[0036] In some embodiments, the tube body further includes a conductive layer 200 and an outer tube 300, with the conductive layer 200 covering the inner tube 100. Static electricity generated by friction between the inner tube 100 and the air is captured by the intermediate conductive layer 200. The outer tube 300 is fitted with the conductive layer 200 to prevent damage to the conductive layer 200 and to prevent leakage from the conductive layer 200 from affecting other structures.

[0037] In some embodiments, the intake pipe further includes a grounding wire 500, one end of which is electrically connected to the conductive layer 200, and the other end of which is used to conduct current.

[0038] Specifically, the end of the grounding wire 500 away from the conductive layer 200 is electrically connected to the vehicle body or engine.

[0039] Through the above scheme, the static electricity generated by the friction between the inner tube 100 and the air is captured by the middle conductive layer 200 and conducted to the vehicle body or engine through the grounding wire 500. Since the vehicle body and engine are made of metal and are grounded, the current can be discharged, thereby eliminating the problem of fine particulate matter being attracted by electrostatic force on the inner tube 100 wall. The outer tube 300 wraps around and protects the conductive layer 200 to prevent it from failing due to wear or impact from the external environment. This continuously eliminates the electrostatic potential energy of the intake pipe wall, avoids the forced adsorption of fine particles by electrostatic force, and allows the filter element surface to accumulate evenly according to the natural filtration law, maintaining the effective cross-sectional area of ​​the airflow channel.

[0040] Understandably, conductive materials are usually metallic, which are easily corroded by moisture. Furthermore, they are expensive and heavy. Therefore, the inner tube 100 is made of a non-conductive material.

[0041] Furthermore, the inner tube 100 can be made of a polymer matrix layer. Inner tubes 100 made of this material have the advantages of being lightweight, low-cost, and highly corrosion-resistant. Secondly, this material has good formability and can be processed into tubes with smooth inner walls, reducing frictional resistance during airflow and lowering intake energy consumption.

[0042] In some embodiments, a metal clamp 400 is also included. The metal clamp 400 is used to connect the pipe body to the air inlet of the air filter 600; the metal clamp 400 is in contact with the conductive layer 200; and the grounding wire 500 is in contact with and connected to the metal clamp 400. The metal clamp 400 serves two purposes: firstly, it secures the connection between the pipe body and the air inlet of the air filter 600, enhancing the sealing and structural stability of the connection and preventing airflow leakage from the connection gaps, thus preventing airflow loss. Secondly, since the metal clamp 400 is in direct contact with the conductive layer 200, static electricity is transferred from the conductive layer 200 through the metal clamp 400 to the grounding wire 500. This design facilitates the connection between the grounding wire 500 and the metal clamp 400. Compared to connecting the grounding wire 500 directly to the conductive layer 200, even if the grounding wire 500 breaks, a new grounding wire 500 can be quickly connected to the metal clamp 400, simplifying maintenance.

[0043] Furthermore, the metal clamp 400 can be a metal cable tie. The metal cable tie has adjustable binding tension, which can flexibly adjust the locking force according to the size compatibility of the tube and the connecting parts. This ensures a tight fit between the tube and the air inlet of the air filter 600, preventing airflow leakage from gaps and resulting in air intake loss, while also avoiding tube deformation due to excessive rigidity.

[0044] In some embodiments, the conductive layer 200 has a bent section 201 at one end near the metal clamp 400; the bent section 201 passes through the outer tube 300.

[0045] Understandably, to ensure sufficient contact area between the bent section 201 and the clamp 400, the bent section 201 can be arranged in a circle, i.e., the bent section 201 is disc-shaped. In this case, if the bent section 201 passes through the outer tube 300, it will completely divide the outer tube 300 into two sections. Therefore, the bent section 201 is located at one end of the outer tube 300, and the bent section 201 contacts the metal clamp 400.

[0046] Through the above solution, regardless of whether the bent section 201 passes through the outer tube 300 or is located at the end of the outer tube 300, the conductive layer 200 can form direct physical contact with the metal clamp 400. This avoids problems such as excessive conductive resistance or disconnection caused by an insufficient contact area between the conductive layer 200 and the metal clamp 400, thus improving electrostatic conduction efficiency. Furthermore, the end of the outer tube 300 can abut against the bent section 201, limiting the relative position of the outer tube 300 and the conductive layer 200. This prevents displacement of the conductive layer 200 or the outer tube 300 due to vibration during vehicle operation, ensuring long-term stable contact between the conductive layer 200 and the metal clamp 400.

[0047] Specifically, the conductive layer 200 is tubular in shape and is fitted with an inner tube 100. This ensures that the inner wall of the conductive layer 200 adheres to the outer wall of the inner tube 100. This guarantees conductivity, allowing static electricity generated throughout the inner tube 100 to be guided by the conductive layer 200. Furthermore, the tight fit between the conductive layer 200 and the inner tube 100 reduces relative displacement between the conductive layer 200 and the inner tube 100 caused by vehicle vibrations, preventing disruption of the static electricity conduction path due to displacement.

[0048] Furthermore, the bent section 201 is annular and extends radially outward along the inner tube 100. It can approach the metal clamp 400 with the shortest distance. In addition, the side of the bent section 201 is perpendicular to the circumference of the outer tube 300, and the end of the outer tube 300 can be more stably abutted against the bent section 201.

[0049] In some embodiments, the end of the bent section 201 is further bent into a contact section 202, the outer peripheral wall of the contact section 202 being flush with the outer peripheral wall of the outer tube 300, and the metal clamp 400 is fitted onto and contacts the contact section 202. The contact section 202 increases the contact area with the metal clamp 400, further improving conductivity stability. This avoids poor contact or excessively small contact area leading to excessive resistance and instability, ensuring that static electricity can be fully transferred to the metal clamp 400 through the contact section 202, improving the uniformity and efficiency of static electricity conduction. The design of the contact section 202 being flush with the outer peripheral wall of the outer tube 300 allows the metal clamp 400 to simultaneously fit the outer tube 300 and the contact section 202, enhancing the locking effect of the metal clamp 400 on the tube body. This strengthens the connection and sealing between the tube body and the air filter inlet, and avoids local stress concentration caused by uneven contact surfaces of the metal clamp 400, reducing the risk of fatigue damage to the tube body or the metal clamp 400.

[0050] Furthermore, the contact section 202 is also cylindrical, with its end connected to the outer edge of the bent section 201. The contact section 202 is coaxially arranged with the inner tube 100. The inner diameter of the contact section 202 is larger than the outer diameter of the inner tube 100, and the outer diameter of the contact section 202 is the same as the outer diameter of the outer tube 300. The cylindrical contact section 202 forms a uniform conductive contact surface around the outer circumference of the inner tube 100. Combined with its connection to the bent section 201, this ensures that static electricity from the conductive layer 200 can be completely transferred to the contact section 202 and then efficiently discharged through contact with the metal clamp 400.

[0051] Furthermore, the section where the conductive layer 200 contacts the inner tube 100 is a wrapping section, and the contact section 202 is bent towards the wrapping section. A insertion cavity is formed between the wrapping section, the bent section 201, and the contact section 202, allowing a portion of the outer tube 300 to be inserted into the insertion cavity. The insertion cavity can wrap and limit the end of the outer tube 300, preventing radial or axial displacement of the outer tube 300 and the conductive layer 200 due to vehicle vibration, thus ensuring the coaxiality between the inner tube 100, the conductive layer 200, and the outer tube 300.

[0052] In some embodiments, the inner wall of the metal clamp 400 is provided with a plurality of protruding limiting members, which are spaced apart along the inner peripheral wall of the metal clamp 400. A limiting groove is formed on the outer peripheral wall of the contact section 202, and a plurality of limiting grooves are spaced apart along the circumferential direction of the contact section 202. The limiting members are engaged in the limiting grooves. After the metal clamp 400 is installed, the limiting members will be engaged in the limiting grooves, thereby preventing the circumferential rotation of the metal clamp 400. This ensures that the current from the conductive layer 200 can be transmitted to the metal clamp 400.

[0053] In another embodiment, the outer peripheral wall of the metal clamp 400 is provided with an annular clamp, and the outer peripheral wall of the contact section 202 is provided with an annular groove. After the metal clamp 400 is installed, the annular clamp is inserted into the groove, thereby preventing the metal clamp 400 from moving along the axial direction of the pipe body and ensuring that the metal clamp 400 can maintain contact with the contact section 202.

[0054] It is understandable that the annular retainer can be located on the outer peripheral wall of the contact section 202, the annular groove can be formed on the inner peripheral wall of the metal retainer, or the metal retainer can be bent outward to form an annular groove.

[0055] In some embodiments, an annular receiving cavity is formed on the outer peripheral wall of the inner tube 100, and both the conductive layer 200 and the outer tube 300 are located within the receiving cavity. The receiving cavity can limit the conductive layer 200 and the outer tube 300, with the two ends of the conductive layer 200 and the outer tube 300 respectively abutting against the two inner walls of the receiving cavity. This prevents the conductive layer 200 or the outer tube 300 from shifting due to vibration during vehicle operation, ensuring that the conductive layer 200 is always in a preset position between the inner tube 100 and the outer tube 300, and guaranteeing stable contact between the conductive layer 200 and the metal clamp 400. At the same time, it prevents the conductive layer 200 from being exposed and thus damaged or malfunctioning.

[0056] Understandably, the receiving cavity extends through the peripheral wall of the outer tube 300. The annular receiving cavity is coaxially arranged with the inner tube 100. The inner wall of the conductive layer 200 is attached to the peripheral wall of the receiving cavity. The two inner end walls of the receiving cavity are respectively close to the two ends of the inner tube 100, and the two end walls respectively abut against the two ends of the conductive layer 200. The two ends of the outer tube 300 are also abutted by the two end walls.

[0057] In other embodiments, the inner tube 100 is a circular tube, and a retaining ring is provided on the outer peripheral wall of the end of the inner tube 100. The ends of the conductive layer 200 and the outer tube 300 are used to abut against the retaining ring. The retaining ring directly abuts against the ends of the conductive layer 200 and the outer tube 300, limiting the conductive layer 200 and the outer tube 300, preventing the conductive layer 200 or the outer tube 300 from shifting due to vibration during vehicle operation, ensuring that the conductive layer 200 is always in a preset position between the inner tube 100 and the outer tube 300, and ensuring stable contact between the conductive layer 200 and the metal clamp 400. At the same time, it prevents the conductive layer 200 from being exposed and thus damaged or malfunctioning.

[0058] Furthermore, two retaining rings are provided, with the conductive layer 200 located between the two retaining rings. The sides of the two retaining rings that are close to each other abut against the two ends of the conductive layer 200 in the axial direction. The two retaining rings axially limit the conductive layer 200.

[0059] Furthermore, the outer tube 300 is also positioned between the two retaining rings, with the sides of the two retaining rings close to each other abutting against the two ends of the outer tube 300 along its axial direction. The two retaining rings provide axial restraint for the outer tube 300.

[0060] It is understandable that, in order to ensure the connection stability between the retaining ring and the inner tube 100, the retaining ring and the inner tube 100 can be integrally molded.

[0061] In some embodiments, the conductive layer 200 is a metal mesh. The metal mesh possesses excellent conductivity, efficiently capturing and conducting static electricity generated by friction between the air and the inner tube 100. Compared to other conductive materials, the metal mesh has lower conductivity resistance and faster static electricity conduction speed, quickly eliminating electrostatic potential energy on the tube wall and preventing dust adsorption caused by temporary accumulation of static electricity on the inner tube 100 wall. Simultaneously, the metal mesh exhibits good structural toughness and strength, adapting to vibrations and temperature changes during vehicle operation, and is not prone to breakage or deformation. Its conductivity remains stable over long-term use, preventing the static electricity discharge function from failing due to damage to the conductive layer 200. Furthermore, the mesh structure of the metal mesh does not obstruct the fit between the inner tube 100 and the outer tube 300, nor does it create additional resistance to airflow within the tube. While ensuring the static electricity discharge function, it also considers the air intake efficiency and structural stability of the tube. Moreover, the cost of the metal mesh material is controllable, facilitating mass production and application.

[0062] In another embodiment, the conductive layer 200 can be a metal sleeve. The all-metal sleeve can completely cover the outer wall of the inner tube 100, quickly capturing the static electricity generated by the friction between the inner tube 100 and the air, and avoiding localized accumulation of static electricity.

[0063] In some embodiments, the outer tube 300 can be made of a polymer matrix layer. This material has the advantages of being lightweight, low-cost, and highly corrosion-resistant. Furthermore, this material has excellent insulation properties, preventing leakage from causing damage to adjacent structures.

[0064] In some embodiments, the inner wall of the outer tube 300 is roughened. This increases the coefficient of friction between the outer tube 300 and the conductive layer 200, effectively limiting axial movement of the outer tube 300 and the conductive layer 200 during vehicle vibration or temperature changes, ensuring that the outer tube 300 is always in a preset position and preventing the conductive layer 200 from being exposed.

[0065] In some embodiments, the outer peripheral wall of the inner tube 100 is rough, thereby increasing the coefficient of friction between the inner tube 100 and the conductive layer 200, which can effectively limit the axial movement of the conductive layer 200 and the inner tube 100 when the vehicle is vibrating or the temperature changes, and prevent the conductive layer 200 from failing to contact the metal clamp 400.

[0066] Furthermore, this application also provides an air intake assembly, which includes an air filter 600, an air filter exhaust pipe 700, and the aforementioned air intake pipe. The air intake pipe is connected to and communicates with the air intake port of the air filter 600, and the air filter exhaust pipe 700 is connected to and communicates with the exhaust port of the air filter 600. The air intake pipe has an electrostatic discharge function, ensuring that dust in the airflow entering the air filter 600 is not adsorbed by the pipe wall, preventing the formation of a dense dust cake layer on the filter element due to localized electrostatic adsorption, extending the filter element's service life, and reducing the frequency of filter element replacement and maintenance costs.

[0067] In some embodiments, the air inlet of the air filter 600 is connected to a connecting pipe, which is inserted into one end of the inner pipe 100. A metal clamp 400 is located on the outer periphery of the connecting pipe and locks the pipe body to the connecting pipe. The connecting pipe is connected to the inner pipe 100 through the metal clamp 400, further optimizing the connection reliability and intake stability of the intake assembly. This ensures smooth airflow into the air filter 600. While achieving the connection, the metal clamp 400 also functions to conduct the current from the conductive layer 200 to the grounding wire 500.

[0068] In some embodiments, the conductive layer 200 is a metal mesh, so the outer tube 300 and the inner tube 100 can be bonded together with adhesive. The adhesive layer adheres to the outer tube 300 and the inner tube 100 through the mesh of the metal mesh. While connecting the inner tube 100 and the outer tube 300, the adhesive layer also fixes the position of the metal mesh, ensuring that the relative positions of the inner tube 100, the conductive layer 200, and the outer tube 300 do not change.

[0069] Furthermore, this application also provides a vehicle comprising: a body, an engine, and the aforementioned intake assembly; the engine is mounted on the body, and the grounding wire 500 in the intake assembly is conductively connected to the body or the engine. The intake pipe of this vehicle has a conductive function, dissipating internal air through static electricity and preventing dust from adhering to the inner wall of the intake pipe due to static electricity. This ensures sufficient air intake, extends service life, and reduces energy consumption.

[0070] It is understandable that since the vehicle itself is grounded, the current generated by the friction between the inner tube 100 and the air is conducted by the conductive layer 200 and transmitted to the metal clamp 400. The current is transmitted to the vehicle body or engine through the grounding wire 500, and then grounded through the vehicle itself to achieve current discharge.

[0071] Although embodiments of this application have been shown and described above, it is understood that the above embodiments are exemplary and should not be construed as limiting this application. Those skilled in the art can make changes, modifications, substitutions and variations to the above embodiments within the scope of this application.
