The air intake and ventilation system includes a first air intake duct, a left port of the air intake duct, a right port of the air intake duct, an air intake duct controller, a second air intake duct, an external dust filter and an air filter element engine. One end of the first air intake duct is connected to the outside. The other end of the first air intake duct is connected to the left port of the air intake duct. The right port of the air intake duct is connected to one end of the second air intake duct. The other end of the second air intake duct is directly or indirectly connected to the engine through an air filter element. The left port of the air intake duct and the right port of the air intake duct are arranged opposite to each other. An external dust filter is arranged on the left port of the air intake duct and the outside of the air intake duct.

[0066] The utility model provides an intake valve assembly, an intake pipe device, an engine assembly and a vehicle. The intake valve assembly is installed in the intake pipe device to adjust the intake state of the intake pipe device, that is, to adjust the connected and closed states of the intake pipe device. The engine assembly includes an engine, an intake pipe device and an exhaust pipe device. The intake part of the engine is connected to the intake pipe device. The exhaust part of the engine is connected to the exhaust pipe device. The vehicle here can be used for the aforementioned engine assembly. The vehicle can be an off-road vehicle, or other traditional vehicles, hybrid vehicles and new energy vehicles.

[0067] Please refer to the attached Figures 1 to 6 The intake valve assembly, intake pipe device, engine assembly and vehicle according to the utility model are described in detail.

[0068] like Figures 1 to 6As shown, the utility model provides an intake valve assembly 110. The intake valve assembly 110 is used for an intake pipe device 100 of an engine. The intake valve assembly 110 may include a valve housing 111 and a valve 113. The valve housing 111 may include a valve hole 111a that is arranged to penetrate along its own extension direction D. When the intake valve assembly 110 is installed to the intake pipe device 100, the extension direction D of the valve housing 111 is consistent with the direction of the center line of the intake pipe device 100. An accommodating groove 121 is formed on the inner wall of the valve housing 111. The valve 113 is rotatably connected to the valve hole 111a around the rotation axis AX, so that the valve 113 can be selectively rotated to a closed position (such as a closed position) that closes the valve hole 111a. Figure 2 The solid line, Figure 3 The dotted line, Figure 4 The solid line, Figure 5 ) and the open position of the open valve hole 111a (as shown Figure 2 The dotted line, Figure 3 The solid line, Figure 4 The dotted line, Figure 5 ). The valve 113 in the open position is accommodated in the accommodating groove 121. In other words, when the valve 113 is in the open position, the valve 113 is accommodated in the accommodating groove 121. Here, the valve 113 being accommodated in the accommodating groove 121 can be understood as the valve 113 being completely accommodated in the accommodating groove 121. Here, the valve 113 being accommodated in the accommodating groove 121 can also be understood as the valve 113 being partially accommodated in the accommodating groove 121.

[0069] According to the intake valve assembly 110 of the utility model, when the intake valve assembly 110 is applied to the intake pipe device 100 of the engine, the intake pipe device 100 can be easily closed and opened. Among them, the valve 113 in the closed position can prevent water from flowing to the engine in a wading environment. Moreover, since the valve housing 111 is provided with a receiving groove 121, the valve 113 in the open state can be accommodated to reduce the space occupied by the valve 113 in the inner cavity of the valve housing 111, thereby reducing the impact on the intake volume, which helps to supply air to the engine more stably. The structure of the utility model is simpler, and while being able to conveniently adjust the open and closed state of the intake pipe device 100, it reduces the impact on the intake volume.

[0070] like Figures 2 to 5As shown, for example, the valve housing 111 has an air inlet end 111b and an air outlet end 111c along its own extension direction D. The valve 113 has a first end 113b and a second end 113c opposite to each other. The rotation axis AX is located at the first end 113b. When the valve 113 is in the open position, the second end 113c is located on the side of the rotation axis AX close to the air inlet end 111b. It can be understood that the valve 113 is rotated in the direction close to the air inlet end 111b to achieve movement to the open position. Similarly, the valve 113 is rotated in the direction close to the air outlet end 111c to achieve movement to the closed position. In this way, when the valve 113 is in the closed position, the valve 113 can be more effectively prevented from opening due to the pressure of water. That is, the valve 113 in the closed position can be more stably maintained in the closed position under the action of hydraulic force in a wading environment, thereby more reliably preventing water from flowing to the engine, thereby achieving the effect of blocking the water flow. In the wading state, water flows into the valve housing 111 from the air inlet end 111b. At this time, if the valve 113 is in the closed position, the hydraulic force of the water is applied to the valve 113 from the air inlet end 111b toward the air outlet end 111c, so that the valve 113 can be kept in the closed position more stably, which is conducive to more reliably blocking the water source.

[0071] See also Figures 2 to 5 Furthermore, the accommodating groove 121 is located on one side of the rotation axis AX close to the air inlet end 111b in the extension direction D of the valve housing 111. This can adapt to the application scenario where the valve 113 rotates toward the air inlet end 111b and switches to the open position.

[0072] See also Figures 2 to 4 Optionally, a stop protrusion 113a is formed on one end face of the valve 113 along its own axial direction. The stop protrusion 113a faces the air inlet end 111b when the valve 113 is in the closed position. The stop protrusion 113a is used to abut against the inner surface of the accommodating groove 121 during the process of the valve 113 moving toward the open position or when the valve 113 is in the open position, so as to limit the valve 113 from continuing to move away from the closed position relative to the valve housing 111, and at the same time, it also helps to reduce the contact area between the valve 113 and the inner surface of the accommodating groove 121, thereby making the resistance of the valve 113 moving out of the accommodating groove 121 smaller.

[0073] For example, the air inlet valve assembly 110 may include a sealing ring. The sealing ring is connected to the valve 113 and is continuously arranged along the circumference of the valve 113. The sealing ring is adapted to be sealed to the inner wall of the valve housing 111 when the valve 113 is in the closed position to block the air inlet end 111b and the air outlet end 111c. By providing the sealing ring, when the valve 113 is in the closed position, the sealing between the valve 113 and the valve housing 111 can be achieved, thereby preventing water from passing through the gap between the valve 113 and the valve housing 111.

[0074] In one example, the inner wall of the valve housing 111 may include a first sealing surface 111e. The first sealing surface 111e is arranged to extend along the circumferential direction of the valve housing 111. The first sealing surface 111e intersects with the extension direction D of the valve housing 111. The intake valve assembly 110 may include a first sealing ring 114. The first sealing ring 114 is connected to the end surface of the valve 113 along the axial direction of the valve 113. The first sealing ring 114 is suitable for sealingly fitting to the first sealing surface 111e when the valve 113 is in the closed position. By providing the first sealing surface 111e and the first sealing ring 114, the gap between the valve 113 and the valve housing 111 can be sealed along the axial direction of the valve 113 when the valve 113 is in the closed position. The axial direction here can also be understood as the thickness direction of the valve 113.

[0075] In another example, the inner wall of the valve housing 111 may include a second sealing surface 111f. The second sealing surface 111f is arranged to extend along the circumference of the valve housing 111. In a direction parallel to the extension direction D of the valve housing 111 and close to the air inlet end 111b, the diameter of the second sealing surface 111f remains unchanged or increases. The air intake valve assembly 110 may include a second sealing ring 115. The second sealing ring 115 is connected to the outer peripheral surface of the valve 113. The second sealing ring 115 is suitable for sealingly fitting to the second sealing surface 111f when the valve 113 is in the closed position. By providing the second sealing surface 111f and the second sealing ring 115, the gap between the valve 113 and the valve housing 111 can be sealed along the radial direction of the valve 113 when the valve 113 is in the closed position. The radial direction here is perpendicular to the aforementioned axial direction.

[0076] exist Figures 2 to 4In the example shown, the inner wall of the valve housing 111 is provided with a first sealing surface 111e and a second sealing surface 111f. The first sealing ring 114 and the second sealing ring 115 are arranged to intersect. The first sealing ring 114 intersects with the extension direction D of the valve housing 111. In a direction parallel to the extension direction D of the valve housing 111 and close to the air inlet end 111b, the diameter of the second sealing surface 111f remains unchanged or increases. The sealing ring may include a first sealing ring 114 and a second sealing ring 115. The first sealing ring 114 is connected to the end surface of the valve 113 along the axial direction of the valve 113. The first sealing ring 114 is adapted to be sealed to the first sealing surface 111e when the valve 113 is in the closed position. The second sealing ring 115 is connected to the outer peripheral surface of the valve 113. The second sealing ring 115 is adapted to be sealed to the second sealing surface 111f when the valve 113 is in the closed position. By providing the first sealing surface 111e and the first sealing ring 114, the gap between the valve 113 and the valve housing 111 can be sealed along the axial direction of the valve 113 when the valve 113 is in the closed position. The axial direction here can also be understood as the thickness direction of the valve 113. By providing the second sealing surface 111f and the second sealing ring 115, the gap between the valve 113 and the valve housing 111 can be sealed along the radial direction of the valve 113 when the valve 113 is in the closed position. The radial direction here is perpendicular to the aforementioned axial direction. By providing two sealing rings, the sealing performance can be improved, thereby obtaining a better waterproof and water blocking effect. The first sealing surface 111e and the second sealing surface 111f are both annular surfaces, and the first sealing surface 111e is connected to the second sealing surface 111f. The inner diameter of the first sealing surface 111e is smaller than the inner diameter of the second sealing surface 111f. The outer diameter of the first sealing surface 111e can be the same as the inner diameter of one end of the second sealing surface 111f.

[0077] See also Figures 2 to 4 For example, the inner wall of the valve housing 111 forms a limiting portion 111d. The cross section of the limiting portion 111d perpendicular to the extension direction D of the valve housing 111 decreases in a direction close to the air inlet end 111b. The first sealing surface 111e is located at the limiting portion 111d.

[0078] See also Figures 2 to 6In addition, the intake valve assembly 110 may further include a rotating shaft 112 and a driving motor 116. The rotating shaft 112 is rotatably arranged in the valve housing 111 around the rotating axis AX. The axis of the rotating shaft 112 is parallel or colinear with the rotating axis AX. The rotating shaft 112 is connected to the valve 113. The driving motor 116 is connected to the valve housing 111. The driving motor 116 may include a motor shaft 116a of the driving motor 116. The motor shaft 116a of the driving motor 116 is transmission-connected to the rotating shaft 112 to drive the rotating shaft 112 to rotate. The driving motor 116 is connected to the rotating shaft 112, and the rotating shaft 112 is connected to the valve 113. When the driving motor 116 is started, the motor shaft 116a of the driving motor 116 can drive the rotating shaft 112 to rotate, thereby driving the valve 113 to rotate, so as to change the position of the valve 113.

[0079] See also Figures 2 to 3 For example, the motor shaft 116a of the driving motor 116 is coaxial with the rotating shaft 112. By arranging the motor shaft 116a of the driving motor 116 coaxially with the rotating shaft 112, the space occupied in the extension direction D of the valve housing 111 can be reduced.

[0080] Optionally, the motor shaft 116a of the drive motor 116 can be connected to the rotating shaft 112 via a spline. This helps to improve the transmission efficiency between the motor shaft 116a of the drive motor 116 and the rotating shaft 112. When the drive motor 116 housing of the drive motor 116 is fixed to the valve housing 111, it is also helpful to prevent the rotating shaft 112 from shaking or swaying.

[0081] Further, the valve housing 111 may include a mounting hole (not shown) suitable for passing the rotating shaft 112. The mounting hole is connected to the valve hole 111a and the outside. The intake valve assembly 110 may also include a third sealing ring. The third sealing ring is sleeved on the outside of the rotating shaft 112. And the third sealing ring is located in the mounting hole. The third sealing ring is suitable for sealing the gap between the rotating shaft 112 and the hole wall of the mounting hole. By arranging the third sealing ring between the rotating shaft 112 and the mounting hole, it is helpful to improve the airtightness between the rotating shaft 112 and the mounting hole.

[0082] See also Figures 1 to 6 The utility model also provides an intake pipe device 100, and the intake pipe device 100 includes the above-mentioned intake valve assembly 110.

[0083] According to the intake pipe device 100 of the utility model, by applying the above-mentioned intake valve assembly 110, the structure is simpler and more compact, and the opening and closing state of the intake pipe device 100 can be conveniently adjusted while reducing the impact on the intake volume.

[0084] Continue reading Figures 1 to 6For example, the intake valve assembly 110 may include an intake end 111b and an outlet end 111c. The intake pipe device 100 may include a first intake pipe 120 and a second intake pipe 130. One end of the first intake pipe 120 is sealed and connected to the intake end 111b. The other end of the first intake pipe 120 is connected to the outside. One end of the second intake pipe 130 is sealed and connected to the outlet end 111c. The other end of the second intake pipe 130 is suitable for being directly or indirectly connected to the engine. When the air is inhaled, the gas flows to the engine through the first intake pipe 120, the intake end 111b of the intake valve assembly 110, the outlet end 111c of the intake valve assembly 110, and the second intake pipe 130 in sequence. When the valve 113 is in the closed position, the valve 113 can be cut off between the first intake pipe 120 and the second intake pipe 130, thereby preventing the second intake pipe 130 from being connected to the outside.

[0085] Further, one of the first air intake pipe 120 and the second air intake pipe 130 and the valve housing 111 of the air intake valve assembly 110 are constructed as an integral component. Taking the first air intake pipe 120 and the valve housing 111 as an integral component as an example, it can be understood that the first air intake pipe 120 and the valve housing 111 are manufactured as an integral component by an integrated manufacturing method. Alternatively, it can be understood that the first air intake pipe 120 and the valve housing 111 are first produced separately, and then assembled together by a non-detachable assembly process such as welding to become a component. This is conducive to simplifying the structure of the air intake pipe device 100, and can also reduce the number of parts and improve assembly efficiency.

[0086] Furthermore, the first air inlet pipe 120 is provided with a water flow hole 122. The water flow hole 122 is arranged near the air inlet valve assembly 110. The water flow hole 122 is used to discharge water when water from the outside spreads to the position of the water flow hole 122.

[0087] The air intake pipe device of the utility model can be used for a passenger car with a deep wading capability or a water floating function.

[0088] like Figure 1 As shown, the intake valve assembly 110 is located between the first intake pipe 120 and the second intake pipe 130 , and the opening and closing of the valve 113 is controlled by an external drive motor 116 .

[0089] like Figure 2 and Figure 5As shown, the intake valve assembly 110 includes a first sealing ring 114, a second sealing ring 115, a rotating shaft 112, a driving motor 116, a valve 113 and an accommodating groove 121. The driving motor 116 is fastened to the first intake pipe 120 with screws. The motor shaft 116a is coaxially arranged with the rotating shaft 112, and the driving shaft is connected to the rotating shaft 112 of the valve 113 through a spline from the inside of the motor. A third sealing ring can be provided on the motor shaft 116a so that the motor shaft 116a can still be effectively sealed when rotating in the mounting hole of the valve housing 111. The driving motor 116 is used to control the opening and closing of the valve 113 to prevent the rotating shaft 112 from shaking.

[0090] Depend on Figure 4 It can be seen that the two sealing rings fit tightly with the valve housing 111, which ensures the sealing and waterproofness of the air intake pipe to the greatest extent. The air intake valve assembly 110 can be connected to the first air intake pipe 120 and the second air intake pipe 130 by bolts to form a whole. A water flow hole 122 is provided at the tail end of the first air intake pipe 120. When a small amount of water from the outside spreads to this place, the water will flow out of the vehicle through the water flow hole 122.

[0091] like Figure 3 As shown, the valve 113 is installed in the valve housing 111 and is arranged corresponding to a receiving groove 121 protruding to the outside on the inner side of the valve housing 111. When the valve 113 is in the open position, the valve 113 is received in the receiving groove 121. At this time, under the non-wading working condition, the first air intake pipe 120 and the second air intake pipe 130 are normally connected to supply air to the engine. The valve 113 does not block the connection between the first air intake pipe 120 and the second air intake pipe 130, and does not affect the intake volume of the first air intake pipe 120 and the second air intake pipe 130 under normal operation of the engine, thereby ensuring the normal operation of the engine. When the water level depth sensor located outside the rearview mirror detects that the water level is too high and water may enter the engine through the air intake pipe, the vehicle control system controls the valve 113 to switch to the closed position, and the first sealing ring 114 and the second sealing ring 115 provide effective waterproof sealing performance. At this time, the driving mode of the vehicle can be converted to electric drive, and the motor provides the kinetic energy for the vehicle to travel. Even if the air inlet of the first air inlet pipe 120 of the vehicle is submerged below the water surface, the vehicle can still be driven normally to achieve the purpose of floating driving of the vehicle.

[0092] The drive motor 116 is fastened to the outside of the first air intake pipe 120 by screws. It does not occupy the internal space of the air intake pipe, which is conducive to improving the compactness of the internal structure of the air intake pipe. The drive motor 116 can be connected to the vehicle wiring harness through a connector, and thus connected to the vehicle control system through the vehicle wiring harness.

[0093] When the vehicle passes through a deep water section or a river, the vehicle control system can actively close the intake valve assembly 110 to prevent external water from entering the engine. In some embodiments, the open state and closed state of the intake valve assembly 110 can be linked to the driving mode. When the vehicle control system obtains the information that the intake valve assembly 110 is closed, it controls the engine to stop working and controls the vehicle's motor to start working. At this time, the vehicle can realize the function of wading and floating.

[0094] In the air intake valve assembly 110 of the utility model, the valve 113 can be configured to be normally open, that is, the valve 113 is in the open position by default in the initial state. When the vehicle enters a deep water area, the vehicle enters a wading mode or a floating mode, and the vehicle control system controls the valve 113 to rotate to a closed position to prevent water from entering the vehicle from the air intake of the engine, thereby protecting the engine. The air intake valve assembly 110 can be configured to be associated with the driving mode of the whole vehicle. When the vehicle enters the wading mode, the water level sensor located at the exterior rearview mirror detects that the water level is too high, and the vehicle control system determines that there may be water entering the engine through the first air intake pipe 120 and the second air intake pipe 130, then the valve 113 is controlled to rotate to a closed position. At this time, the driving mode of the vehicle is converted to electric drive, and the motor provides kinetic energy in the form of the vehicle. Even if the air intake of the first air intake pipe 120 of the vehicle is submerged below the water surface, the vehicle can be driven normally to achieve the floating of the vehicle.

[0095] The utility model also provides an engine assembly, which may include an engine and the above-mentioned intake pipe device 100 , wherein the intake pipe device 100 is connected to the engine.

[0096] According to the engine assembly of the utility model, by applying the above-mentioned air intake pipe assembly, it is possible to effectively prevent water from entering in a wading environment, and the air intake volume of the engine can be guaranteed, and the structure is simpler and more compact, which helps to improve the performance of the engine assembly. In the engine assembly of the utility model, the valve 113 can automatically control the opening and closing state of the air intake passage between the first air intake pipe 120 and the second air intake pipe 130 as the motor shaft 116a of the drive motor 116 rotates, and the waterproof performance is excellent, which can meet the needs of deep wading of the vehicle and floating driving of the whole vehicle. At the same time, the structural design of the utility model is more compact, and the assembly operation is more convenient. After adding this structure, the impact on the air intake volume of the engine can be reduced.

[0097] The utility model also provides a vehicle, which comprises the above-mentioned engine assembly.

[0098] According to the vehicle of the utility model, by applying the above-mentioned engine assembly, the waterproof performance of the vehicle in a wading environment can be improved, thereby better protecting the engine.

[0099] For example, the vehicle may include a water level sensor disposed at the exterior rearview mirror. The vehicle has a normal road driving mode, a wading mode, and a floating mode. When the vehicle enters a flooded road surface or a deep water location such as a river channel or a pit, the water level sensor automatically detects the water level. When the water level exceeds a set threshold, the vehicle control system controls the valve 113 of the intake valve assembly 110 to switch to a closed position and turns on the wading mode. In the wading mode, the engine stops working, and the starting motor uses the power of the power battery to drive the vehicle. Among them, the threshold of the water level is usually set to the height from the ground of the air inlet of the first intake pipe 120 minus the safety distance, which is the distance between the water surface and the air inlet of the first intake pipe 120. When the vehicle continues to travel to deeper waters and the four wheels are completely off the ground, the vehicle starts the floating mode. When the vehicle is traveling on a normal road, the valve 113 of the intake valve assembly 110 is in an open position, and the intake passage between the first intake pipe 120 and the second intake pipe 130 is in an open state. At this time, the first intake pipe 120 and the second intake pipe 130 are in normal use. When the vehicle is traveling in a deep water area and enters the wading mode, the drive motor 116 synchronously drives the intake valve 113 to rotate to a closed position, and the intake passage between the first intake pipe 120 and the second intake pipe 130 is in a closed state, thereby blocking external water from entering the engine. The switching of the position of the valve 113 here can be linked to the driving mode. When the vehicle detects that the valve 113 is in a closed position, the engine stops working and the motor starts working at the same time. At this time, the vehicle can achieve wading mode or floating mode.
