Description

Technical Field

[0001] The utility model relates to the technical field of vehicles, in particular to an air intake regulating mechanism, an engine, a power assembly and a vehicle. Background Art

[0002] When the engine is working, it needs to inhale clean and sufficient fresh air through the intake system. In addition, some systems that require pressure balance or venturi structures (such as carbon canister desorption system, crankcase ventilation system, etc.) will be connected to the intake system. These systems will produce a large amount of oil and gas when working, and enter the cylinder with the airflow of the intake system to burn. However, when the engine is turned off, some oil and gas will evaporate into the intake system and diffuse into the outside air through the intake port, causing air pollution.

[0003] In order to prevent oil and gas from diffusing into the air, some technologies close the air intake system by setting active substance adsorption or closing the air intake grille. However, the active substance adsorption cannot be completely adsorbed due to the layout position and composition restrictions, and the diffusion inhibition effect is poor. The closing method of the air intake grille requires complex actuators and active control by a controller, which is costly and has a complex structure. Utility Model Content

[0045] In the description of the present invention, "first feature" or "second feature" may include one or more of the features.

[0046] In the description of the present invention, "multiple" means two or more, and "several" means one or more.

[0047] The air intake adjustment mechanism 1 according to an embodiment of the present utility model will be described below with reference to the accompanying drawings.

[0048] like Figure 1-Figure 4 As shown, the air intake adjustment mechanism 1 according to the embodiment of the utility model includes an opening and closing member 100 and a transmission assembly 200 .

[0049] The opening and closing member 100 is suitable for controlling the opening and closing of the air intake 410 of the engine 2. One end of the transmission component 200 is suitable for transmission connection with the throttle valve and the other end is transmission connection with the opening and closing member 100 to control the opening and closing of the opening and closing member 100 and the throttle valve to open and close synchronously.

[0050] The shape of the opening and closing member 100 must be compatible with the cross-sectional shape of the air inlet 410 and can completely cover the air inlet 410 when closed.

[0051] According to the air intake regulating mechanism 1 of the embodiment of the utility model, the transmission assembly 200 is respectively connected to the throttle valve and the opening and closing member 100 to control the synchronous opening and closing of the opening and closing member 100 and the throttle valve. That is to say, when the throttle valve is switched to the closed state, the throttle valve can drive the opening and closing member 100 to move together through the transmission assembly 200, and then drive the opening and closing member 100 to cover the air inlet 410, and when the throttle valve is switched from the closed state to the open state, the throttle valve can drive the opening and closing member 100 to open the air inlet 410 through the transmission assembly 200.

[0052] In this way, when the throttle valve is opened, the opening and closing member 100 can open the air intake port 410 so that the engine 2 can normally inhale fresh air, ensuring that the engine 2 has sufficient air intake, and the oil and gas generated by the carbon canister purge system and the crankcase ventilation system can follow the airflow into the cylinder for combustion; and when the throttle valve is closed, the opening and closing member 100 can synchronously close the air intake port 410. At this time, the opening and closing member 100 isolates the inside of the engine 2 from the outside world, and then the opening and closing member 100 can be used to prevent the oil and gas generated by the carbon canister purge system and the crankcase ventilation system from diffusing to the outside world, thereby effectively avoiding oil and gas pollution of the air.

[0053] Furthermore, compared with the conventional technology of preventing the diffusion of oil and gas by adsorption of active substances or closing the air intake grille, the embodiment of the utility model links the action of the opening and closing member 100 with the throttle valve through the transmission component 200, and the transmission component 200 mechanically transmits the opening and closing member 100 and the throttle valve, without an electric actuator, and does not need to identify the accelerator pedal depth to open or close the air intake port 410, and the mechanical transmission process has a low delay. When the throttle valve is opened, the opening and closing member 100 synchronously opens the air intake port 410, and when the throttle valve is closed, the opening and closing member 100 synchronously closes the air intake port 410. The transmission structure is simple, can directly and effectively isolate the inside and outside of the engine 2, prevent the oil and gas from diffusing into the air, and is conducive to reducing costs.

[0054] In addition, for hybrid models, the air inlet 410 can be closed by the opening and closing member 100 in pure electric mode. In this way, when the vehicle is wading in pure electric mode, water outside the vehicle and the surge caused by the vehicle will not enter the air filter, let alone the engine 2, thereby ensuring that the engine 2 starts normally after the vehicle leaves the wading area, greatly improving the wading reliability of the vehicle.

[0055] In this way, the air intake regulating mechanism 1 according to the embodiment of the utility model can be linked with the throttle valve, and has the advantages of simple structure, no delay and low cost.

[0056] In some specific embodiments of the present invention, Figure 2-Figure 4 As shown, the transmission assembly 200 includes an active component 210 and a transmission component 220 .

[0057] The active member 210 is in transmission connection with the throttle valve, and one end of the transmission member 220 is in transmission connection with the active member 210 and the other end is in transmission connection with the opening and closing member 100. Therefore, when the throttle valve rotates, the active member 210 can be driven to rotate, and the opening and closing member 100 can be driven to rotate through the active member 210 and the transmission member 220, so as to control the opening and closing member 100 to cover the air inlet 410 or open the air inlet 410, and only a simple crank connecting rod structure is used, and there is no need for a controller to control the transmission assembly 200, so the structure is simpler, and it is more convenient to control the opening and closing of the air inlet 410, and it is easy to implement.

[0058] In addition, it should be noted that the opening and closing member 100 can open and close the air inlet 410 by flipping, for example, the central axis of the opening and closing member 100 is parallel to one side of the air inlet 410, and the opening and closing member 100 can flip around the central axis to open or close the air inlet 410; or, the opening and closing member 100 can open and close the air inlet 410 by rotating, for example, the central axis of the opening and closing member 100 is perpendicular to the plane where the air inlet 410 is located, and the opening and closing member 100 can rotate around the central axis to open or close the air inlet 410; or, the opening and closing member 100 can open and close the air inlet 410 by pushing and pulling the opening and closing member 100, for example, the opening and driving assembly 200 can drive the opening and closing member 100 to move along the length direction of the air inlet 410 to open or close the opening and closing member 100. Of course, the opening and closing method of the opening and closing member 100 is not limited to this, as long as the air inlet 410 can be opened and closed cyclically.

[0059] Furthermore, the active member 210 and the throttle valve rotate synchronously.

[0060] In this way, when the engine 2 is turned off, the throttle is closed, and the transmission assembly 200 can be used to synchronously drive the opening and closing member 100 to close the air inlet 410. When the engine 2 is started, the throttle is opened, and the transmission assembly 200 can be used to synchronously drive the opening and closing member 100 to open the air inlet 410. In this way, when the engine 2 is turned off, the opening and closing member 100 can synchronously close the air inlet 410 to effectively prevent the oil and gas from diffusing from the air inlet 410 to the air, and when the engine 2 is started, the opening and closing member 100 can synchronously open the air inlet 410 to allow the engine 2 to normally inhale air.

[0061] In some specific embodiments of the present invention, Figure 3 and Figure 4 As shown, the rotation axis of the active member 210 coincides with the rotation axis of the throttle valve.

[0062] Specifically, the throttle has a rotating shaft, and the engine 2 can drive the rotating shaft to rotate the throttle around the rotating shaft. One end of the active member 210 can be connected to the rotating shaft of the throttle. When the throttle rotates, the active member 210 can rotate along the rotating shaft of the throttle. This is not only conducive to simplifying the transmission connection structure of the active member 210 and the throttle, making it easier to connect, but also makes the synchronous rotation structure of the active member 210 and the throttle simpler, making it easier to achieve synchronous rotation of the active member 210 and the throttle.

[0063] In some specific embodiments of the present invention, Figure 3 and Figure 4 As shown, the active member 210 is configured with a slide groove 211 , and one end of the transmission member 220 is slidably connected to the slide groove 211 .

[0064] Among them, the slide groove 211 extends along the length direction of the active member 210. When the active member 210 rotates synchronously with the throttle valve, the relative position between the active member 210 and the air inlet 410 will change, and then the relative position between the slide groove 211 and the air inlet 410 will change, that is, the distance between the slide groove 211 and the air inlet 410 will change. At this time, one end of the transmission member 220 can move in the slide groove 211 to drive the transmission member 220 to move through the active member 210, and use the transmission member 220 to drive the opening and closing member 100 to move relative to the air inlet 410, so that the relative position of the opening and closing member 100 and the air inlet 410 can be adjusted to achieve the opening and closing member 100 covering or opening the air inlet 410.

[0065] In some specific embodiments of the present invention, Figure 3 and Figure 4 As shown, the rotation axis of the active member 210 is located in the slide slot 211 and adjacent to one end of the slide slot 211 .

[0066] In this way, when the active member 210 rotates along its rotation axis, the slide groove 211 can rotate with one end of the slide groove 211 as the center, that is, one end of the slide groove 211 coincides with the rotation axis of the active member 210 (that is, the rotation axis of the throttle valve). Therefore, when the active member 210 rotates, the position of one end of the slide groove 211 can remain unchanged. In this way, after the transmission component 200 drives the opening and closing member 100 to fully open the air inlet 410, one end of the transmission component 220 can always cooperate with one end of the slide groove 211, that is, after the air inlet 410 is fully opened, the transmission component 220 can remain stationary, and the active member 210 no longer drives the opening and closing member 100 to move relative to the air inlet 410 through the transmission component 220. This is conducive to simplifying the movement of the transmission component 200, which can not only ensure that the transmission component 200 can drive the opening and closing member 100 to open or close the air inlet 410, but also reduce the movement of the transmission component 200, which is conducive to protecting the transmission component 200 and extending the service life of the transmission component 200.

[0067] In some specific embodiments of the present invention, Figure 1-Figure 4 As shown, the air intake adjustment mechanism 1 has a first direction and a second direction that are orthogonal to each other. The first direction and the second direction are perpendicular to the rotation axis of the active member 210 . The opening and closing member 100 and the active member 210 are arranged at intervals along the first direction.

[0068] As shown in the figure, the direction indicated by arrow A is the first direction, and the direction indicated by arrow B is the second direction. In this embodiment, the first direction can be understood as the horizontal direction, and the second direction can be understood as the vertical direction.

[0069] When the throttle is in a closed state, the angle between the active member 210 and the second direction is A; when the throttle switches from a closed state to an open state, the active member 210 rotates by at least β; wherein α and β satisfy: α<β.

[0070] It should be noted that when the throttle is in the open state, the opening angle of the throttle will be adjusted according to the intake demand of the engine 2, and when the engine 2 is in the idle state, the opening angle of the throttle is the smallest, that is, when the engine 2 enters the idle state from being turned off, the rotation angle of the throttle is β.

[0071] By setting the angle between the active member 210 and the second direction to α, and α<β, when the engine 2 is started from being turned off, the active member 210 and the throttle valve can simultaneously rotate by an angle β, so that the active member 210 can be rotated from one side of the second direction to the other side of the second direction. At this time, the distance between the end of the slide groove 211 away from the rotation axis of the active member 210 and the air inlet 410 increases, and the transmission member 220 can slide along the slide groove 211 to the end of the slide groove 211 close to the rotation axis of the active member 210, and the transmission member 220 can drive the opening and closing member 100 to open the air inlet 410, so that the engine 2 can take in air normally.

[0072] For example, the angle α is 7° and the angle β is 10°.

[0073] When the engine 2 is turned off, the throttle is closed, and the angle between the active member 210 and the second direction is 7°; when the engine 2 is started, the throttle is opened at the first time, the engine 2 enters the idle state, the throttle rotates 10°, and at the same time, the active member 210 rotates 10° synchronously, and the active member 210 pulls the transmission member 220 in the direction away from the air inlet 410, thereby driving the opening and closing member 100 to flip and open the air inlet 410. At the same time, one end of the transmission member 220 will move along the slide groove 211 to the position of the slide groove 211 close to the rotation axis of the active member 210, and always remain in this position when the throttle is opened.

[0074] In some specific embodiments of the present invention, Figure 3 As shown, when the throttle is in the open state, projected onto a plane perpendicular to the second direction, the distance between one end of the transmission member 220 and the rotation axis of the opening and closing member 100 is equal to the distance between the air inlet 410 and the rotation axis of the active member 210.

[0075] In this way, on the one hand, the length of the transmission member 220 can be prevented from being too short, so that the active member 210 can drive the opening and closing member 100 to flip and open the air inlet 410 through the transmission member 220. On the other hand, the length of the transmission member 220 can be prevented from being too long. After the throttle starts, one end of the transmission member 220 can always be maintained on the side of the rotation axis of the slide groove 211 close to the active member 210. In this way, when adjusting the throttle opening, the transmission member 220 can remain stationary, and then the position of the opening and closing member 100 can be kept unchanged, so that the air inlet 410 is in an open state, which is convenient for the engine 2 to intake air.

[0076] In some specific embodiments of the present invention, Figure 3 and Figure 4 As shown, the opening and closing member 100 is rotatably connected to one side of the air inlet 410 .

[0077] Specifically, the opening and closing member 100 can be hinged to the lower side of the air inlet 410, and when the throttle drives the transmission assembly 200 to move, the opening and closing member 100 can rotate around one side of the air inlet 410 to open or close the air inlet 410. In addition, it can be understood that by connecting the opening and closing member 100 to the air inlet 410, it is not only easy to install, but also the opening and closing member 100 has enough rotation space, so that the opening and closing member 100 can be rotated to open or close the air inlet 410.

[0078] In some specific embodiments of the present invention, Figure 2 As shown, the opening and closing member 100 includes a main body 110 and an extension rod 120 .

[0079] The air inlet 410 has a first side 411 and a second side 412 relative to each other, the main body 110 is rotatably connected to the first side 411 and is suitable for covering the air inlet 410, the extension rod 120 is connected to the main body 110, and one end of the extension rod 120 extends beyond the first side 411 in a direction away from the second side 412; wherein the other end of the transmission assembly 200 is rotatably connected to one end of the extension rod 120.

[0080] That is, the opening and closing member 100 is hinged to one side of the air inlet 410 , and the transmission assembly 200 is hinged to one end of the extension rod 120 .

[0081] In addition, by extending the extension rod 120 beyond the first side 411 in the direction away from the second side 412, the force arm of the transmission assembly 200 driving the opening and closing member 100 to flip can be greater than 0, so that the transmission assembly 200 drives the opening and closing member 100 to flip, so as to realize that the throttle drives the opening and closing member 100 to open or close the air inlet 410 through the transmission assembly 200.

[0082] Furthermore, if Figure 2 and Figure 3 As shown, one end of the extension rod 120 extends beyond the main body 110 .

[0083] It can be understood that the main body 110 only needs to be able to completely cover the air inlet 410. By setting the extension rod 120 beyond the main body 110, it is helpful to reduce the area of ​​the main body 110, thereby saving materials of the opening and closing member 100 and reducing the weight of the opening and closing member 100, making it easier for the transmission component 200 to drive the opening and closing member 100 to flip. Moreover, the extension rod 120 is longer, and the force arm of the transmission component 200 to drive the opening and closing member 100 to flip can be longer, which makes it more labor-saving for the transmission component 200 to drive the opening and closing member 100 to flip.

[0084] In some specific embodiments of the present invention, Figure 2-Figure 4 As shown, the extension rod 120 is connected to a side of the main body 110 ; and / or, the extension rod 120 is connected to a side of the main body 110 that faces away from the air inlet 410 .

[0085] It is understandable that, along the rotation axis of the opening and closing member 100 , the extension rod 120 can be connected to any position in the length direction of the main body 110 .

[0086] For example, the extension rod 120 can be connected to one side of the main body 110 in the length direction, or the extension rod 120 can be connected between the two ends of the main body 110 in the length direction. In this case, the extension rod 120 needs to be arranged on the side of the main body 110 that is away from the air inlet 410. This can ensure that the side of the opening and closing member 100 facing the air inlet 410 is flat, so that the opening and closing member 100 can better cover the air inlet 410 and effectively prevent oil and gas from diffusing from the air inlet 410 to the outside air.

[0087] In some specific embodiments of the present invention, Figure 2 As shown, the air intake regulating mechanism 1 further includes a sealing member 300 , which is disposed at least one of the air intake port 410 and the main body 110 , and is used to seal a gap between the main body 110 and the air intake port 410 .

[0088] For example, the seal 300 may be provided on one side of the main body 110 facing the air inlet 410; or, the seal 300 may be provided around the air inlet 410; or, the seal 300 may be provided on one side of the main body 110 facing the air inlet 410 and around the air inlet 410. In this way, when the opening and closing member 100 closes the air inlet 410, the seal 300 may seal the gap between the opening and closing member 100 and the air inlet 410, so that the opening and closing member 100 can better cover the air inlet 410, further preventing the oil and gas from diffusing from the air inlet 410 to the outside air.

[0089] In some specific embodiments of the present invention, the air intake regulating mechanism 1 further includes an elastic member (not shown in the figure).

[0090] The elastic member is installed on the opening and closing member 100 , and the elastic member has an elastic force that drives the opening and closing member 100 to cover the air inlet 410 .

[0091] In this way, when the throttle valve switches from an open state to a closed state, the elastic force of the elastic member can drive the opening and closing member 100 to rotate, so that the opening and closing member 100 can be flipped to a position to close the air inlet 410, and the elastic force of the elastic member can press the opening and closing member 100 against the air inlet 410, thereby maintaining the state of the opening and closing member 100, so that the opening and closing member 100 can better cover the air inlet 410.

[0092] The engine 2 according to the embodiment of the present invention is described below with reference to the drawings. The engine 2 includes an intake guide pipe 400, an intake manifold 500 and an intake adjustment mechanism 1 according to the above embodiment of the present invention.

[0093] The air intake duct 400 has an air intake port 410, and a throttle is provided in the air intake manifold 500 for adjusting the air intake amount of the air intake manifold 500. The air intake regulating mechanism 1 is connected to the throttle in a transmission manner and is used to open and close the air intake port 410. The air intake regulating mechanism 1 can be arranged at the air intake port 410 or in the air intake duct 400, and when the throttle is closed, the air intake regulating mechanism 1 can close the air intake line of the air intake duct 400.

[0094] According to the engine 2 of the embodiment of the utility model, by utilizing the intake regulating mechanism 1 according to the above embodiment of the utility model, the intake regulating mechanism 1 can be linked with the throttle valve, and has the advantages of simple structure, no delay and low cost.

[0095] In some specific embodiments of the present invention, the engine 2 further includes an air filter, which is connected between the intake duct 400 and the intake manifold 500 , and the opening and closing member 100 is located on a side of the air filter facing the intake duct 400 .

[0096] That is to say, the opening and closing member 100 can be set at any position before the air filter, so that when the engine 2 is turned off and the opening and closing member 100 covers the air inlet 410, the oil and gas will not diffuse to the outside through the air inlet 410, and the engine 2 also stops taking in air. At this time, the outside air no longer flows through the air filter, that is, the air filter can stop working after the engine 2 is turned off, which is beneficial to extending the service life of the air filter.

[0097] The power assembly according to the above embodiment of the present invention will be described below with reference to the accompanying drawings. The power assembly includes the engine 2 according to the above embodiment of the present invention.

[0098] According to the power assembly of the embodiment of the utility model, by utilizing the engine 2 according to the above embodiment of the utility model, the air intake adjustment mechanism 1 can be linked with the throttle valve, which has the advantages of simple structure, no delay and low cost.

[0099] A vehicle according to an embodiment of the present invention will be described below with reference to the accompanying drawings. The vehicle includes an engine 2 according to the above embodiment of the present invention or a powertrain according to the above embodiment of the present invention.

[0100] According to the vehicle of the embodiment of the utility model, by utilizing the engine 2 according to the above embodiment of the utility model or the power assembly according to the above embodiment of the utility model, the air intake adjustment mechanism 1 can be linked with the throttle valve, which has the advantages of simple structure, no delay and low cost.
