Description

Technical Field

[0001] The invention relates to the technical field of vehicle air intake systems, in particular to a high-position air intake pipe with a dust suction component. Background Art

[0002] The high-position intake pipe, also known as the "wading hose", is mainly used in the modification of off-road vehicles. Its function is to prevent water from entering the engine when the car is wading, thereby avoiding engine damage. The principle of this modification is to cut off the shunt pipe originally located at the position of the car's grille, and drill holes from the fenders on both sides of the car, install a sealed and waterproof intake engineering plastic pipe, connect and seal it with the original car shunt pipe of the engine, and the design of the high-position intake pipe takes into account the operating principle of the internal combustion engine. During the operation of the internal combustion engine, especially during the compression stroke, the piston will move upward, compressing the air in the cylinder to generate high temperature, which is used to evaporate the liquid fuel into gas. If the engine inhales water at this time, since water can hardly be compressed, it will cause the piston to fail to reach the top dead center, which will cause the engine to stall or even be damaged. Therefore, the high-position intake pipe is located higher, which can effectively prevent water from entering the engine through the air intake when driving on a flooded road.

[0003] Although the high-position intake pipe can prevent water from entering the engine, in order to prevent dust in the air from entering the engine when inhaling air, an air filter is usually installed between the diverter pipe and the engine intake end. Its function is to filter the air entering the engine to protect the interior of the engine from damage by dust and other particulate matter.

[0004] In the prior art, as air is inhaled for a long time, the filter element of the air filter absorbs a lot of dust, resulting in a heavy filtering burden on the air filter. At the same time, the filter element of the air filter needs to be cleaned frequently. The installation position of the air filter is usually inside the vehicle body, which is troublesome to disassemble and clean, affecting the normal use of the vehicle. Infrequent cleaning will affect the engine's air intake, thereby affecting the engine's power output.

[0005] The root cause of the above series of problems is that the dust entering the high-position air intake pipe cannot be discharged autonomously.

[0006] To this end, the present invention aims to propose a high-position air intake pipe which can autonomously discharge the dust accumulated inside to the outside of the pipe through a dust suction component. The main purpose of the technical solution of the present invention is to discharge part of the dust from the inside of the pipe to the outside of the pipe to reduce the pressure of the air filter element and assist in dust removal, rather than absolute dust removal. Summary of the invention

[0007] The technical solution of the present invention aims at the technical problem that the existing technical solutions are too simple, and provides a solution that is significantly different from the existing technologies. Specifically, the purpose of the present invention is to provide a high-position air intake pipe with a dust absorption component to solve the problem mentioned in the above background technology that dust is difficult to be discharged after entering the high-position air intake pipe, thereby causing the filter element of the air filter to become clogged and need to be frequently disassembled and cleaned.

[0008] To achieve the above object, the present invention provides the following technical solution: a high-position air intake pipe with an ash suction assembly, comprising a main pipe and a rain cover installed on the top thereof, and also comprising an elastic rectifier plate arranged inside the air intake end of the main pipe for blocking ash and discharging ash to the edge, a sliding ring located at the bottom of the elastic rectifier plate for collecting edge dust, and an ash suction mechanism for discharging the edge dust of the sliding ring out of the main pipe and collecting it again in a bumpy state of the car; The elastic rectifying plate is arranged as a spiral structure inclined along the air intake direction, and the outer edge of the sliding ring and the inner wall of the main pipe form a groove with the inclined surface facing the inner wall of the main pipe.

[0009] Preferably, a center column rotatably connected to the rain cover is provided at the center of the elastic rectifier plate, and the inner edge of the elastic rectifier plate is in contact with the outer wall of the center column, and the outer edge of the elastic rectifier plate is close to the inner wall of the main pipe, and filter holes are evenly opened inside the elastic rectifier plate.

[0010] Preferably, a fixing rod fixed to one end of the elastic rectifier plate is fixed to the upper outer surface of the center column, and a moving block fixed to the other end of the elastic rectifier plate is provided on the lower outer surface of the center column, and the outer wall of the moving block is inclined toward the side wall on the upper surface of the elastic rectifier plate.

[0011] Preferably, a sliding column is fixed to the end surface of the moving block, and a sliding groove slidably matched with the sliding column is formed on the outer wall of the central column.

[0012] Preferably, the lower end of the sliding ring is slidably arranged with the inner wall of the main pipe, and the bottom of the moving block is located inside the sliding ring and fixed with a T-shaped slider, and the inner wall of the sliding ring is provided with an annular groove that slidably cooperates with the T-shaped slider.

[0013] Preferably, the outer wall of the main pipe is provided with a counterweight ring that slides with the main pipe, and a traction rope is fixedly connected between the bottom of the sliding ring and the top of the counterweight ring. The traction rope is set through the main pipe, and limiting rings are fixed at both ends of the counterweight ring on the outer wall of the main pipe.

[0014] Preferably, the ash suction mechanism includes ash collecting barrels distributed at equal angles on the outside of the main pipeline, a detachable sealing cover is provided on the top of the ash collecting barrel, and a diversion pipe penetrating the inner wall of the main pipeline is provided at the upper end of the ash collecting barrel, and the port of the diversion pipe is located above the sliding ring, and an air outlet pipe is connected between the bottom of the ash collecting barrel and the main pipeline to connect the two.

[0015] Preferably, a support ring is fixed to the inner wall of the ash collecting cylinder, a filter plate slidingly matched with the inner wall of the ash collecting cylinder is arranged on the top of the support ring, and a connecting column is fixedly connected between the filter plate and the sealing cover.

[0016] Preferably, a valve plate that fits with the diverter pipe is disposed in the port of the diverter pipe, and a bottom rod that penetrates to the bottom of the sliding ring is fixedly connected to the bottom of the valve plate, and the bottom rod is threadedly connected to the sliding ring.

[0017] Compared with the prior art, the present invention has the following beneficial effects: (1) In the present invention, during the driving process of the automobile, air enters from the air inlet end of the main duct. If there is less dust on the upper surface of the elastic rectifier plate, most of the air passes through the elastic rectifier plate and is filtered through the filter holes. Since the elastic rectifier plate is inclined along the air inlet direction, a small amount of dust on the upper surface of the elastic rectifier plate will fall outward due to the airflow and the inclined surface to be collected in the groove formed by the outer side of the sliding ring and the inner wall of the main duct. Even if the dust moves along the upper surface of the elastic rectifier plate to the end under the influence of the airflow, it can be guided to the edge of the elastic rectifier plate by the inclined surface of the side wall of the moving block to slide into the groove on the outer side of the sliding ring for collection. If there is more dust accumulated on the surface of the elastic rectifier plate, the fluidity of the elastic rectifier plate is reduced. Under the influence of the air, the elastic rectifier plate will generate a certain centrifugal force when it rotates, making it easier for the dust on the upper surface to slide outward, thereby preventing the elastic rectifier plate from being blocked while blocking the dust, thereby ensuring the air flow of the main duct and allowing dust collection.

[0018] (2) In the present invention, when the vehicle is bumpy during driving, the counterweight ring will slide longitudinally. If the counterweight ring moves upward, the pulling force of the traction rope on the sliding ring is released, and the elastic rectifier plate can pull the sliding ring to slide upward. While sliding, the sliding ring will push the dust in the groove upward. While sliding, the bottom rod will rotate due to the thread on the outer wall of the bottom rod. The bottom rod will drive the valve plate to rotate in the shunt pipe. After the shunt pipe is connected, the airflow will flow with the dust collected in the groove outside the sliding ring. During the flow, the dust is filtered through the filter plate and retained on the upper surface of the filter plate. Even if the sliding ring causes a slight disturbance in the collected dust when sliding, the valve plate has already rotated while the sliding ring moves upward, so the dust can be absorbed. When the weight ring slides down and resets, the sliding ring slides down and resets under the action of the traction rope, and the bottom rod rotates and resets, so that the valve plate rotates and resets to close the diversion pipe. The ash suction mechanism distributed at equal angles can increase its ash collecting capacity. During regular maintenance, you only need to open the sealing cover on the top of the ash collecting cylinder to take out the filter plate through the connecting column to clean the dust on the surface. During the bumpy process, the weight ring slides longitudinally, which can continuously discharge the dust in the groove into the main pipe and collect it. Not only is the maintenance operation convenient, but the dust collected in the air entering the main pipe can be discharged out of the pipe, thereby reducing the burden on the air filter. The main purpose is to discharge part of the dust from the inside of the pipe to the outside of the pipe to reduce the pressure of the air filter element and assist in dust removal, rather than absolute dust removal.

[0027] The outer wall of the main pipeline 1 is provided with a counterweight ring 11 that slides with the main pipeline 1. A traction rope 12 is fixedly connected between the bottom of the sliding ring 9 and the top of the counterweight ring 11. The traction rope 12 is set through the main pipeline 1. Limiting rings 13 are fixed at both ends of the outer wall of the main pipeline 1 at the counterweight ring 11.

[0028] The ash suction mechanism includes ash collecting cylinders 14 distributed at equal angles on the outside of the main pipeline 1, a detachable sealing cover is provided on the top of the ash collecting cylinder 14, and a bypass pipe 15 penetrating the inner wall of the main pipeline 1 is provided at the upper end of the ash collecting cylinder 14, and the port of the bypass pipe 15 is located above the sliding ring 9, and an air outlet pipe 16 is connected between the bottom of the ash collecting cylinder 14 and the main pipeline 1 to connect the two.

[0029] A support ring 17 is fixed to the inner wall of the ash collecting cylinder 14 , a filter plate 18 is provided on the top of the support ring 17 and is slidably matched with the inner wall of the ash collecting cylinder 14 , and a connecting column is fixedly connected between the filter plate 18 and the sealing cover.

[0030] A valve plate 19 matching with the shunt pipe 15 is arranged in the port thereof, and a bottom rod 20 penetrating to the bottom of the sliding ring 9 is fixedly connected to the bottom of the valve plate 19 , and the bottom rod 20 is threadedly connected to the sliding ring 9 .

[0031] Working principle: When using the high-position air intake pipe with dust absorption assembly, firstly, the bottom of the main pipe 1 is connected to the air filter inside the car, and the air filter is connected to the air intake end of the engine. The rain cover 2 located on the top of the main pipe 1 can prevent rainwater from entering the main pipe 1 on rainy days; Then, during normal driving, when the car has not passed through a bumpy section, the engine will use the air intake end at the top of the main pipe 1 to absorb air. Since the elastic rectifier plate 5 is made of a thin elastic material, and the center column 3 and the sliding ring 9 are both made of relatively light materials, when the air passes through the elastic rectifier plate 5, the dust in the air will be blocked on the upper surface of the elastic rectifier plate 5 due to the filter holes evenly opened on the elastic rectifier plate 5. As the dust on the upper surface of the elastic rectifier plate 5 decreases and the fluidity decreases, the spirally structured elastic rectifier plate 5 will rotate on the rain cover 2 using the center column 3 driven by the air. During the rotation, since the sliding column 7 is stuck in the sliding groove 8, the center column 3 also drives the moving block 6 to rotate synchronously, and the T-shaped slider 10 at the bottom of the moving block 6 slides in the annular groove 101 on the inner wall of the sliding ring 9.

[0032] At this time, the counterweight ring 11 is in a stationary state and is located on the limiting ring 13 at the bottom. Under the pulling action of the traction rope 12, the sliding ring 9 pulls the moving block 6 through the T-shaped slider 10, and the moving block 6 pulls the elastic rectifier plate 5 to deform. One end of the elastic rectifier plate 5 is fixed to the outer wall of the fixed rod 4, so that the elastic rectifier plate 5 is stretched, and the sliding column 7 on the outer wall of the moving block 6 is located at the bottom of the slide groove 8; Based on the above state, the elastic rectifier plate 5 is tilted along the air intake direction, and a small amount of dust on the upper surface of the elastic rectifier plate 5 will fall outward to the groove formed by the outer side of the sliding ring 9 and the inner wall of the main pipe 1 due to the airflow and the tilted surface. At the same time, when the elastic rectifier plate 5 is rotated due to reduced fluidity, a certain centrifugal force will be generated to make the dust on the upper surface more easily slide to the outside, thereby preventing the elastic rectifier plate 5 from being blocked. Even if the dust moves to the end along the upper surface of the elastic rectifier plate 5 driven by the airflow, it can be guided to the edge of the elastic rectifier plate 5 by the inclined surface of the side wall of the moving block 6 to slide to the groove on the outer side of the sliding ring 9 and be collected, thereby blocking the dust while ensuring the air flow of the elastic rectifier plate 5, and can collect most of the dust; Finally, it is inevitable that the off-road vehicle will bump during driving. During the movement of the counterweight ring 11, the vehicle body will cause the counterweight ring 11 to slide on the outer wall of the main pipe 1 when bumping, and under the limit of the top limit ring 13, the moving distance of the counterweight ring 11 is short. During the sliding process of the counterweight ring 11, the pulling force of the traction rope 12 on the sliding ring 9 is released, so that the elastic rectifier plate 5 is deformed and reset, so that the sliding column 7 on the outer wall of the moving block 6 slides upward in the sliding groove 8, and the moving block 6 is driven to slide through the T-shaped slider 10. The ring 9 slides upward, and the dust in the groove is pushed upward while sliding. The thread on the outer wall of the bottom rod 20 drives the bottom rod 20 to rotate while sliding. The length of the slide groove 8 is limited so that the sliding distance of the sliding ring 9 is limited to the lower end of the outer edge of the sliding ring 9 being attached to the bottom of the shunt pipe 15. At the same time, the thread density on the bottom rod 20 is set so that when the sliding ring 9 moves to the highest point, the bottom rod 20 rotates ninety degrees, and the bottom rod 20 drives the valve plate 19 to rotate in the shunt pipe 15. The shunt pipe 15 After the conduction, part of the airflow will flow into the main pipeline 1 along the shunt pipe 15, the dust collecting cylinder 14 and the air outlet pipe 16, and the airflow will flow mixed with the dust collected in the groove outside the sliding ring 9. Through the inclined side design of the sliding ring 9, when the intake air contacts the inclined surface, the direction of the intake air will also be diverted to the intake end of the shunt pipe 15 under the compulsion of the inclined surface, so as to achieve the effect of diverting the intake air and discharging dust. During the flow, the dust is filtered through the filter plate 18 and retained on the upper surface of the filter plate 18. Even if the sliding ring 9 makes the collected dust The dust is slightly disturbed, but the valve plate 19 has rotated while the sliding ring 9 moves up. The dust collecting capacity can be increased by using the dust collecting mechanism with equal angle distribution. During regular maintenance, it is only necessary to open the sealing cover on the top of the dust collecting cylinder 14 to remove the filter plate 18 through the connecting column to clean the dust on the surface. The operation is convenient and can reduce the burden of the air filter. When the counterweight ring 11 slides down and resets, the sliding ring 9 slides down and resets under the action of the traction rope 12, and the bottom rod 20 rotates and resets, so that the valve plate 19 rotates and resets to close the shunt pipe 15. During the bumping process, the counterweight ring 11 slides up and down, and the dust in the groove formed by the sliding ring 9 and the main pipe 1 can be continuously discharged from the main pipe 1 and collected.
