Description

Technical Field

[0001] This application relates to the field of vehicle intake manifold technology, and more specifically, to an anti-clogging intake manifold for a range-extender engine. Background Technology

[0002] The intake manifold itself typically doesn't have a dedicated "filter." The core component responsible for filtering the air entering the engine is the air filter, located at the very beginning of the engine's intake system, before the air enters the intake manifold. Air first passes through the air filter, is filtered, then passes through the throttle body and the intake manifold, finally entering each cylinder. Its function is to prevent impurities such as dust, grit, insects, and pollen from directly entering the engine cylinders. However, because existing intake manifolds are designed with sufficiently smooth inner walls to reduce friction and ensure uniform airflow, the air filter element accumulates a significant amount of dust over time, resulting in a heavy filtration load and potentially affecting the normal operation of the vehicle.

[0003] Therefore, a clog-resistant intake manifold for range-extender engines is needed to solve the above problems. Utility Model Content

[0004] The summary section of this application is intended to provide a brief overview of the concepts, which will be described in detail in the detailed description section below. This summary section is not intended to identify key or essential features of the claimed technical solutions, nor is it intended to limit the scope of the claimed technical solutions.

[0005] To address the technical problems mentioned in the background section, some embodiments of this application provide an anti-clogging range extender engine intake manifold, comprising: an intake manifold with an air inlet and uniformly distributed air outlets; a purification mechanism connected to the air inlet via a flange; the purification mechanism including a flange seat at the bottom, a fixed housing at the middle, and an intake pipe at the top; the flange seat, the fixed housing, and the intake pipe being fixedly connected to each other; an air filter being installed inside the fixed housing; two vertically distributed fixed brackets being fixedly installed inside the intake pipe; a rotating rod being rotatably connected between the two fixed brackets via a bearing; a spirally arranged elastic baffle being provided on the outer periphery of the rotating rod; a sliding groove being provided on the outer periphery of the rotating rod; a sliding block being fixedly installed at the inner end of the elastic baffle, which slides against the side wall of the sliding groove; and three sets of vertically distributed limiting rings being fixedly installed inside the intake pipe.

[0006] Furthermore, each set of limiting rings is symmetrically arranged vertically, and guide rods are fixedly provided on the three sets of limiting rings. Three counterweight rings are slidably arranged vertically on the guide rods. The three counterweight rings are respectively located at the three sets of limiting rings. Two vertically symmetrical sliding grooves are opened on the inner circumference of the counterweight rings. The cross-section of the counterweight rings is T-shaped. The outer circumference of the elastic baffle is fixedly provided with plug-in claws that slide and cooperate with the sliding grooves.

[0007] Furthermore, a cleaning strip is fixedly provided at the bottom end of the elastic baffle, and the inner end of the cleaning strip is fixedly connected to the outer periphery of the rotating rod. A dust collection ring is fixedly provided at the lower end of the air inlet pipe, and the cleaning strip can fit against the upper surface of the dust collection ring. The cleaning strip has an arc-shaped end and an inclined end at the connection end away from the elastic baffle. The outer end of the inclined end gradually narrows from top to bottom. A filter plate is installed in the middle of the filter box. A vent is provided at the inner end of the filter box and between the upper and lower parts of the filter box and the air inlet pipe. A fixed sleeve is fixedly provided at the vent inside the air inlet pipe. The fixed sleeve is circular and has a dust discharge chamber of about one-quarter size. A torsion rod is rotatably connected inside the fixed sleeve. A torsion spring is connected between the torsion rod and the fixed sleeve. One end of the torsion rod extends into the air inlet pipe and is inclined so as to fit against the wall of the inclined end. An opening and closing plate is fixedly provided at the end of the fixed sleeve inserted into the torsion rod. The opening and closing plate can close the dust discharge chamber in the normal state.

[0008] Furthermore, the outer periphery of the air intake pipe is provided with two circumferentially distributed protrusions, and two filter boxes are inserted between the two protrusions. The two filter boxes are provided with magnetic attraction mechanisms at their close ends. The magnetic attraction mechanism includes a magnet block and a magnetic attraction cavity. The magnet block can be inserted into the magnetic attraction cavity by magnetic attraction. The protrusions are provided with insertion cavities for the magnet block to pass through. The insertion cavities are inserted and matched with the magnet block. The two filter boxes are fixed with connecting plates at their close ends. The connecting plates are provided with threaded insertion holes.

[0009] The beneficial effects of this application are as follows: 1. By setting the elastic baffle in a spiral shape, it can not only filter dust but also collect dust downwards along the spiral direction. When a large amount of dust filters on the elastic baffle and clogs the filter holes, and air cannot or is reduced from flowing directly downwards through the filter holes, the elastic baffle can rotate. The wind propels the dust downwards, and the cleaning strip fixed to the rotating rod pushes the dust outwards for collection. This reduces the frequency of air filter clogging at the fixed housing and achieves an overall anti-clogging function for the intake manifold.

[0010] 2. The counterweight ring has a large weight and is more susceptible to vibration. By using the counterweight ring set around the elastic baffle and connecting it with the plug claw, the elastic baffle is shaken circumferentially, which can accelerate the dust removal rate of the elastic baffle and further improve the self-cleaning efficiency of the dust at the elastic baffle.

[0019] This disclosure will now be described in detail with reference to the accompanying drawings and embodiments.

[0020] Reference Figure 1-5A clog-resistant range extender engine intake manifold includes: an intake manifold 10, with an intake port 12 and evenly distributed outlets 13. A purification mechanism 11 is flanged to the intake port 12. The purification mechanism 11 includes a flange seat 14 at the bottom, a fixed housing 15 at the middle, and an intake pipe 16 at the top. The flange seat 14, the fixed housing 15, and the intake pipe 16 are fixedly connected to each other. An air filter is installed inside the fixed housing 15. Two vertically distributed fixed brackets 20 are fixed inside the intake pipe 16. A rotating rod 21 is rotatably connected between the two fixed brackets 20 via a bearing. A spirally arranged elastic baffle 23 is provided on the outer periphery of the rotating rod 21. A sliding groove 22 is provided on the outer periphery of the rotating rod 21. A sliding block that slides against the side wall of the sliding groove 22 is fixed to the inner end of the elastic baffle 23. Three sets of vertically distributed limiting rings 36 are fixed inside the intake pipe 16, each set of limiting rings 36 being symmetrically arranged vertically. Three sets of limiting rings 36 are fixed with guide rods 19. Three counterweight rings 24 are slidably arranged on the guide rods 19. The three counterweight rings 24 are located at the three sets of limiting rings 36 respectively. Two vertically symmetrical sliding grooves 25 are opened on the inner circumference of the counterweight rings 24. The cross-section of the counterweight rings 24 is T-shaped. The outer circumference of the elastic baffle 23 is fixed with a plug claw 26 that slides with the sliding groove 25. The counterweight rings 24 are slidably arranged on the guide rods 19. During the movement of the vehicle body, vibration will occur, so that some of the vibration force will be transmitted to the counterweight rings 24 (such as vertical force). As the counterweight rings 24 slide up and down in the guide rods 19, the elastic baffle 23 connected to the counterweight rings 24 through the plug claws 26 will vibrate up and down, so that the elastic baffle 23 will undergo elastic deformation, so that the elastic baffle 23 will have a vertical extension and contraction state in the air intake pipe 16, thereby accelerating the falling rate of dust attached to the elastic baffle 23.

[0021] Reference Figure 6-7A cleaning strip 32 is fixedly provided at the bottom of the elastic baffle 23. The inner end of the cleaning strip 32 is fixedly connected to the outer periphery of the rotating rod 21. A dust collection ring 35 is fixedly provided on the lower side of the elastic baffle 23 inside the air inlet pipe 16. The dust collection ring 35 is fixedly provided at the lower end of the air inlet pipe 16. The cleaning strip 32 can fit against the upper end surface of the dust collection ring 35. The cleaning strip 32 has an arc-shaped end 33 and an inclined end 34 at the connection end away from the elastic baffle 23. The outer end of the inclined end 34 (the part where the cleaning strip 32 fits against the dust collection ring 35) gradually narrows from top to bottom. A filter plate 37 is installed in the middle of the filter box 17. A vent 27 is provided at the inner end of the filter box 17 and between the upper and lower parts of the filter box 17 and the air inlet pipe 16. A fixing sleeve 28 is fixedly provided at the vent 27 inside the air inlet pipe 16. The fixing sleeve 28 is circular and has about one-quarter of a dust discharge chamber. A torsion bar 29 is rotatably connected inside the sleeve 28. A torsion spring 30 is connected between the torsion bar 29 and the fixed sleeve 28. One end of the torsion bar 29 extends into the air inlet pipe 16 and is inclined so as to fit against the wall of the inclined end 34. An opening and closing plate 31 is fixed to the end of the torsion bar 29 inserted into the fixed sleeve 28. The opening and closing plate 31 can close the dust discharge chamber under normal conditions. The cleaning bar 32 can rotate under blocked conditions, so that the inclined end 34 pushes the inclined end of the torsion bar 29, so that the torsion bar 29 overcomes the torsion force of the torsion spring 30 and rotates, thereby causing the opening and closing plate 31 at the dust discharge chamber to rotate and open. At the same time, during the rotation of the cleaning bar 32, the arc-shaped end 33 that abuts against the dust collection ring 35 is arc-shaped, which can push the dust outward during the rotation of the cleaning bar 32. Some air carrying dust enters the filter box 17 through the upper vent 27. After being filtered by the filter plate 37, it is discharged into the air inlet pipe 16 through the lower vent 27.

[0022] Reference Figure 3-4 Two circumferentially distributed protrusions are provided on the outer periphery of the intake pipe 16. Two filter boxes 17 are inserted between the two protrusions. Magnetic attraction mechanisms 18 are provided at the close ends of the two filter boxes 17. Each magnetic attraction mechanism 18 includes a magnet and a magnetic cavity. The magnetic attraction mechanism 18 includes an electromagnet fixed on the filter box 17 and a magnetic cavity opened on the filter box 17. The magnet can be magnetically attracted and inserted into the magnetic cavity. The protrusions have insertion cavities for the magnet to pass through, and the insertion cavities are inserted and matched with the magnet. A connecting plate is fixed at the close ends of the two filter boxes 17. The connecting plate has threaded insertion holes. The two filter boxes 17 are attached to the protrusions of the intake pipe 16 and can move circumferentially. The magnet is inserted into the magnetic cavity through the insertion cavity at the protrusion, thereby temporarily attracting the two filter boxes 17 with magnetic force. Then, threaded parts are installed at the connecting plate at the close ends of the two filter boxes 17 for fixed connection, so that the filter boxes 17 are completely fixed to the intake pipe 16.

[0023] Working process or usage method: 1. The flange seat 14 is installed at the purification mechanism 11 through the flange connection, so that the air inlet pipe 16 is partially connected to the purification mechanism 11. The air filter is installed in the fixed housing 15. Under vibration, air enters through the upper end of the air inlet pipe 16. When passing through the filter hole of the elastic baffle 23, the dust in the air will be blocked on the upper surface of the elastic baffle 23. In the subsequent process, the dust on the elastic baffle 23 will move downwards with the elastic baffle 23 and fall to the dust collection ring 35 for collection.

[0024] 2. Place the two filter boxes 17 against the convex plate portion of the air intake pipe 16, allowing them to move circumferentially. Insert the magnet block into the magnetic suction cavity through the insertion cavity at the convex plate, thereby enabling the two filter boxes 17 to be temporarily attracted by magnetic force. Then, install threaded parts at the connecting plate at the close ends of the two filter boxes 17 for fixed connection, so that the filter boxes 17 are completely fixed on the air intake pipe 16.

[0025] 3. The counterweight ring 24 is slidably mounted on the guide rod 19. During the movement of the vehicle body, it will vibrate, and some of the vibration force will be transmitted to the counterweight ring 24 (such as the force in the vertical direction). As a result, the counterweight ring 24 slides up and down within the guide rod 19, thereby causing the elastic baffle 23 connected to the counterweight ring 24 via the plug claw 26 to vibrate up and down. This causes the elastic baffle 23 to undergo elastic deformation, resulting in the elastic baffle 23 extending and contracting in the vertical direction within the air intake pipe 16, thereby accelerating the rate at which dust adhering to the elastic baffle 23 falls off.

[0026] 4. The cleaning strip 32 can rotate in a blocked state, thereby causing the inclined end 34 to push the inclined end of the torsion bar 29, so that the torsion bar 29 can rotate against the torsion of the torsion spring 30, thereby causing the opening and closing plate 31 at the dust discharge chamber to rotate and open. At the same time, during the rotation of the cleaning strip 32, the arc-shaped end 33 that abuts against the dust collection ring 35 is arc-shaped, which can push the dust outward during the rotation of the cleaning strip 32. Some air carrying dust enters the filter box 17 through the upper vent 27. After being filtered by the filter plate 37, it is discharged into the air inlet pipe 16 through the lower vent 27. By installing a baffle at the inner end of the dust collection ring 35, the amount of dust collected in the dust collection ring 35 can be increased.

[0027] 5. When the blockage of the elastic baffle 23 increases, the pressure received at the elastic baffle 23 also increases, which reduces the amount of air passing through the elastic baffle 23. As the downward flow on the surface of the elastic baffle 23 increases, the single elastic baffle 23 part located at the rotating rod 21 rotates. The force generated during the rotation and the wind work together to act on the dust, making it easier for the dust to slide down to the dust collection ring 35.
