Description

Technical Field

[0001] This application relates to the field of vehicle engine technology, and more particularly to an intake bypass valve and a vehicle. Background Technology

[0002] In the automotive market, gasoline vehicles widely use turbocharging technology, and the ECRV valve used in conjunction with it has become an indispensable product.

[0003] The ECRV valve, also known as the intake bypass valve, is located on the pipeline after the turbocharger and before the throttle body. Its outlet is connected to the intake pipe after the air filter. The function of the ECRV valve is to protect the turbocharger. After the throttle body is closed, the ECRV valve opens, and some high-pressure gas flows into the intake pipeline through the ECRV valve, which serves to relieve pressure and prevent high-pressure gas from flowing back into the turbocharger, causing turbocharger surge or even damage.

[0004] Currently, in ECRV valves, the moving valve core, under the suction force of the coil when energized, moves the sealing element to open. A balance hole is provided on the sealing element, allowing moisture to easily enter the ECRV valve. To prevent moisture from affecting the normal operation of the coil, ECRV valves are usually installed upside down, with the moving valve core below the coil, facilitating the drainage of condensate. However, this also limits the installation method and location of the ECRV valve, affecting improvements in the layout of the turbocharger, air filter, etc. Utility Model Content

[0005] In order to solve the above-mentioned technical problems, or at least partially solve the above-mentioned technical problems, this application provides an intake bypass valve and a vehicle to block water vapor, prevent water vapor from affecting the normal operation of the coil, and realize the flexible arrangement of the intake bypass valve.

[0006] The first aspect of this application provides an intake bypass valve, comprising:

[0007] A sealing sleeve having a receiving cavity, one end of which is open and the other end is closed;

[0008] The valve core has one end extending into the receiving cavity and is able to slide relative to the sealing sleeve;

[0009] A sealing cap is connected to the other end of the moving valve core and extends partially into the receiving cavity through the opening. The sealing cap has a balance hole that communicates with the receiving cavity.

[0010] The moving valve core is configured to drive the sealing cap to reciprocate, thereby opening or closing the passage of the intake bypass valve.

[0011] This intake bypass valve, by setting a sealing sleeve, a moving valve core, and a sealing cap, allows the moving valve core to drive the sealing cap to move and open or close the channel. The sealing sleeve guides the movement of the moving valve core. Since the sealing cap extends into the receiving cavity through the opening and the other end of the receiving cavity is closed, water vapor entering through the balance hole on the sealing cap enters the receiving cavity of the sealing sleeve. The water vapor is blocked by the sealing sleeve and cannot contact the coil of the intake bypass valve, thus preventing water vapor from affecting the normal operation of the coil. This allows the intake bypass valve to be flexibly installed upright or upside down, which facilitates the arrangement of the intake bypass valve and adapts to the layout improvements of the turbocharger, air filter, etc.

[0012] In some embodiments, the sealing sleeve includes a first sleeve and a second sleeve connected together, one end of the first sleeve is closed, one end of the second sleeve is open, the inner diameter of the first sleeve is smaller than the inner diameter of the second sleeve, one end of the moving valve core extends into the first sleeve, and the sealing cap extends into the second sleeve.

[0013] The first cavity of the first sleeve and the second cavity of the second sleeve together constitute the receiving cavity of the sealing sleeve. The first sleeve guides the moving valve core, while the second sleeve allows the sealing cap to extend into it. Thus, a labyrinth seal is formed between the second sleeve and the sealing cap, which can separate water vapor entering through the balance hole, so that condensate is stored in the receiving cavity of the sealing sleeve and cannot enter the area where the coil is located.

[0014] Furthermore, the closed end of the first sleeve can also limit the movement of the moving valve core.

[0015] In some embodiments, the first sleeve extends into the second sleeve with an extension edge, the extension edge surrounding the moving valve core.

[0016] The extension edge serves two purposes: firstly, it extends the first sleeve, thus stably guiding and limiting the movement of the moving valve core. Secondly, the extension edge, in conjunction with the sealing cap and the second sleeve, allows moisture to enter the area between the extension edge and the second sleeve as much as possible, preventing excessive moisture from entering the first sleeve and affecting the movement of the moving valve core.

[0017] In some embodiments, an elastic element is further included; the elastic element is sleeved on the moving valve core, with one end limited to the sealing cap and the other end limited to the stepped surface formed by the second sleeve and the first sleeve, and the elastic element is configured to drive the moving valve core to move the sealing cap to close the channel.

[0018] Compared to having the elastic element inside the moving valve core, the sealing cap can provide a larger support surface for the elastic element, allowing for the use of a spring with a larger cross-section, thus providing stable support for the moving valve core.

[0019] In some embodiments, the sealing sleeve has a buffer protrusion at its closed end that protrudes into the accommodating cavity to buffer the moving valve core.

[0020] By setting a buffer protrusion, the movement of the moving valve core can be buffered, avoiding hard collisions and collision noise.

[0021] In some embodiments, the sealing sleeve is made of plastic;

[0022] And / or, the portion of the cavity wall that contacts the moving valve core is provided with a lubricating coating.

[0023] By using a plastic sealing sleeve, the problem of rusting can be avoided, and the sealing sleeve can also be prevented from becoming magnetized, which would affect the driving of the moving valve core after the coil is energized. It can also buffer the force of the moving valve core, preventing damage to the moving valve core due to hard impacts, and also avoid noise caused by impacts.

[0024] The lubricating coating reduces friction between the moving valve core and the sealing sleeve, providing smooth movement of the moving valve core and preventing jamming. This reduces the movement time of the moving valve core when driven by the coil or elastic element, thereby improving the accuracy of the intake bypass valve.

[0025] In some embodiments, a stationary valve core is also included; the sealing sleeve abuts against or is connected to the stationary valve core, and when the moving valve core moves toward the stationary valve core, it drives the sealing cap to open the channel.

[0026] By setting the sealing sleeve to abut or connect to the stationary valve core, the intake bypass valve has a compact structure, which helps to reduce the overall size of the intake bypass valve in the moving direction of the moving valve core and realize the miniaturization design of the intake bypass valve.

[0027] In some embodiments, it also includes:

[0028] A coil assembly, including a support and a coil wound around the outside of the support;

[0029] The stationary valve core is at least partially disposed on the inner side of the bracket, and the closed end of the sealing sleeve is relatively close to the stationary valve core;

[0030] An elastic element is configured to drive the moving valve core to move away from the stationary valve core, so that the sealing cap closes the passage;

[0031] When the coil is energized, it causes the moving valve core to move closer to the stationary valve core, thereby opening the channel with the sealing cap.

[0032] By setting up a coil assembly, an elastic element, and a stationary valve core, the reciprocating movement of the moving valve core can be achieved through the coil and the elastic element, thereby enabling the sealing cap to open or close the passage of the intake bypass valve, so that the intake bypass valve can perform the corresponding function.

[0033] In some embodiments, the device further includes a valve body and a valve cover connected to each other and surrounding an installation cavity, wherein the coil assembly, the sealing sleeve and the stationary valve core are all disposed in the installation cavity, the sealing sleeve is sandwiched between the valve cover and the bracket and a sealing element is provided between the sealing sleeve and the valve cover, the valve cover has a through hole and the sealing cap is sealed through the through hole.

[0034] The valve body and valve cover provide mounting cavities for the coil assembly, sealing sleeve, and stationary valve core, and fix the stationary valve core, sealing sleeve, and coil assembly. The valve cover also guides the movement of the sealing cap, improving the stability of the sealing cap during movement.

[0035] A second aspect of this application provides a vehicle including an intake bypass valve as described in any of the preceding claims.

[0036] The vehicle has the technical effect of the intake bypass valve provided in the first aspect. Attached Figure Description

[0051] To better understand the above-mentioned objectives, features, and advantages of this application, the solution of this application will be further described below. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0052] Many specific details are set forth in the following description in order to provide a full understanding of this application, but this application may also be implemented in other ways different from those described herein; obviously, the embodiments in the specification are only some embodiments of this application, and not all embodiments.

[0053] Currently, turbocharging technology is widely used in gasoline vehicles in the automotive market, making the intake bypass valve an indispensable product. The intake bypass valve (Emission Control Regulator Valve), also known as the intake bypass valve, is located on the pipeline after the turbocharger and before the throttle valve, with its outlet connected to the intake manifold after the air filter. When the throttle valve is closed, the turbocharger cannot stop rotating instantly, and the boost pressure remains, causing an increase in pressure in the afterburner pipeline. This leads to air flowing back into the turbocharger, causing surge and even damage to the turbocharger. Therefore, the function of the intake bypass valve is to open after the throttle valve is closed, allowing some high-pressure gas to flow into the intake pipeline through the intake bypass valve, thus relieving pressure.

[0054] When the vehicle accelerates, the intake bypass valve closes, and the high-pressure gas pressurized by the turbocharger flows into the intake manifold through the post-compression pipeline. When the vehicle decelerates, the intake bypass valve opens, and some of the high-pressure gas flows into the intake pipeline through the intake bypass valve, serving as a pressure relief function.

[0055] Currently, the moving valve core of the intake bypass valve opens by moving the sealing element under the suction force of the coil when it is energized. A balance hole is provided on the sealing element, allowing moisture to easily enter the intake bypass valve. To prevent moisture from affecting the normal operation of the coil, the intake bypass valve is usually installed upside down, with the moving valve core below the coil, facilitating the drainage of condensate. However, this also limits the installation method and location of the intake bypass valve, affecting improvements to the layout of the turbocharger, air filter, etc.

[0056] Based on this, this application provides an intake bypass valve and a vehicle. By providing a sealing sleeve in the intake bypass valve, water vapor entering through the balance hole of the sealing cap is blocked, preventing water vapor from affecting the normal operation of the intake bypass valve coil. This allows the intake bypass valve to be installed either upright or upside down, facilitating its arrangement. Specifically, when the intake bypass valve is installed upright, the moving valve core is located above the stationary valve core; when the ECRV is installed upside down, the moving valve core is located below the stationary valve core.

[0057] Reference Figures 1 to 3 Some embodiments of this application provide an intake bypass valve, including a sealing sleeve 3, a moving valve core 4, and a sealing cap 5.

[0058] The aforementioned sealing sleeve 3 has a receiving cavity 3a, one end of which is open and the other end is closed, with the closed end relatively close to the stationary valve core 2. One end of the aforementioned moving valve core 4 extends into the receiving cavity 3a and is able to slide relative to the sealing sleeve 3.

[0059] The sealing cap 5 is connected to the other end of the moving valve core 4, and part of it extends into the receiving cavity 3a through the opening. The sealing cap 5 has a balance hole 5a that communicates with the receiving cavity 3a. The moving valve core 4 drives the sealing cap 5 to move back and forth, so that the sealing cap opens or closes the passage of the intake bypass valve (not shown in the figure).

[0060] The sealing cap 5 extends into the receiving cavity 3a through the opening, and the closed end of the receiving cavity 3a is relatively close to the static valve core 2. Thus, water vapor entering through the balance hole 5a enters the receiving cavity 3a of the sealing sleeve 3, where it is blocked, preventing it from affecting the normal operation of the intake bypass valve coil 12. Furthermore, the sealing sleeve 3 also blocks oil in the gas, preventing oil from entering the area where the coil 12 is located.

[0061] It should be noted that, referring to Figure 1 The aforementioned moving valve core 4 reciprocates in the first direction, thereby driving the sealing cap 5 to open or close the intake bypass valve passage. The bidirectional arrow X in the diagram represents the first direction.

[0062] The intake bypass valve provided in this embodiment of the application, by setting a sealing sleeve 3, a moving valve core 4 and a sealing cap 5, provides guidance for the movement of the moving valve core 4. Since the sealing cap 5 extends into the receiving cavity 3a from the opening and the other end of the receiving cavity 3a is closed, the water vapor entering through the balance hole 5a on the sealing cap 5 enters the receiving cavity 3a of the sealing sleeve 3. The water vapor is blocked by the sealing sleeve 3 and cannot contact the coil 12 of the intake bypass valve, thus avoiding the water vapor from affecting the normal operation of the coil 12. This allows the intake bypass valve to be flexibly installed upright or upside down, which facilitates the arrangement of the intake bypass valve and adapts to the improved layout of the turbocharger, air filter, etc.

[0063] In some embodiments, the sealing sleeve 3 is made of plastic. This avoids the problem of the sealing sleeve 3 rusting and also prevents the sealing sleeve 3 from being magnetized and affecting the driving of the valve core 4 after the coil 12 is energized.

[0064] Furthermore, a lubricating coating can be applied to the portion of the cavity wall of the aforementioned receiving cavity 3a that contacts the moving valve core 4. This lubricating coating reduces friction between the moving valve core 4 and the sealing sleeve 3, ensuring smooth movement of the moving valve core 4 and preventing jamming. This reduces the movement time of the moving valve core 4 when driven by the coil 12 and the elastic element 6, thereby improving the accuracy of the intake bypass valve. The lubricating coating can be a PTFE (Polytetrafluoroethylene) coating. Of course, if the self-lubricating effect of the sealing sleeve 3 is good, then a lubricating coating is unnecessary.

[0065] In addition, the sealing sleeve 3 is made of plastic, which can buffer the force of the moving valve core 4, avoid damage to the moving valve core 4 due to hard impact, and also avoid noise caused by impact.

[0066] To improve the buffering effect, a buffer protrusion can be made on the sealing sleeve 3 at its closed end protruding into the receiving cavity 3a to buffer the moving valve core 4. The buffer protrusion can be formed by the sealing sleeve 3 being recessed inward.

[0067] It should be noted that the aforementioned sealing sleeve 3 can be integrally molded by injection molding, which has high production efficiency and facilitates the assembly of the intake bypass valve.

[0068] In some embodiments, refer to Figure 1 and Figure 2 The aforementioned sealing sleeve 3 includes a first sleeve 31 and a second sleeve 32 that are connected to each other. One end of the first sleeve 31 is closed, and one end of the second sleeve 32 is open. The inner diameter of the first sleeve 31 is smaller than the inner diameter of the second sleeve 32. One end of the moving valve core 4 extends into the first sleeve 31, and the sealing cap 5 extends into the second sleeve 32.

[0069] Understandably, the first cavity 31a of the first sleeve 31 and the second cavity 32a of the second sleeve 32 together constitute the receiving cavity 3a of the sealing sleeve 3. The first sleeve 31 serves to guide the moving valve core 4, while the second sleeve 32 allows the sealing cap 5 to extend into it, thus forming a labyrinth seal between the second sleeve 32 and the sealing cap 5. This seal can separate water vapor entering through the balance hole 5a, allowing condensate to be stored in the receiving cavity 3a of the sealing sleeve 3 and preventing it from entering the area where the coil 12 is located. Therefore, when the intake bypass valve is installed upside down, the condensate will be discharged through the balance hole 5a.

[0070] Furthermore, the closed end of the first sleeve 31 can limit the movement of the moving valve core 4. That is, when the moving valve core 4 moves towards the stationary valve core 2 under the action of the coil attraction and contacts the closed end of the first sleeve 31, it indicates that the movement of the moving valve core 4 has reached the position. At this time, due to the limitation of the closed end of the first sleeve 31, the moving valve core 4 can no longer move.

[0071] It should be noted that the outer peripheral wall of the aforementioned moving valve core 4 is in contact with the inner wall of the first sleeve 31, so that the moving valve core 4 can move stably within the first sleeve 31, avoiding shaking of the moving valve core 4 during movement.

[0072] Reference Figure 2 The first sleeve 31 extends into the second sleeve 32 with an extension edge 311, which surrounds the moving valve core 4.

[0073] Understandably, the extension edge 311 serves two purposes: firstly, it extends the first sleeve 31, thereby stably guiding and limiting the movement of the moving valve core 4; secondly, the extension edge 311, in conjunction with the sealing cap 5 and the second sleeve 32, allows moisture to enter the area between the extension edge 311 and the second sleeve 32 as much as possible, preventing excessive moisture from entering the first sleeve 31 and affecting the movement of the moving valve core 4.

[0074] Reference Figure 2 The intake bypass valve also includes an elastic element 6, which is sleeved on the moving valve core 4, with one end limited to the sealing cap 5 and the other end limited to the stepped surface formed by the first sleeve 31 and the second sleeve 32. The elastic element 6 is used to drive the moving valve core to move the sealing cap 5 to close the passage.

[0075] By setting the elastic element 6 to be sleeved on the moving valve core 4, and using the stepped surface formed by the first sleeve 31 and the second sleeve 32 to support the elastic element 6, a larger cross-section elastic element 6 can be selected, so that the elastic element 6 provides more stable support for the moving valve core 4 and the sealing cap 5.

[0076] Of course, in another scenario, the moving valve core can have an inner cavity, with the elastic element positioned within this cavity and confined between the closed ends of the moving valve core and the sealing sleeve. When the moving valve core moves towards the stationary valve core, it compresses the elastic element. Thus, after the coil is de-energized, the elastic element can still drive the moving valve core away from the stationary valve core. However, compared to having the elastic element fitted onto the moving valve core, the cross-section of the elastic element is relatively smaller in this case, but it helps to reduce the radial dimension of the sealing sleeve. Therefore, the placement of the elastic element can be chosen appropriately according to actual needs; it can be placed inside or outside the moving valve core.

[0077] The aforementioned elastic element 6 can be selected as a spring. When the elastic element is located inside the moving valve core, it can be selected as an elastic gasket.

[0078] Reference Figure 1 and Figure 3 In some embodiments, the intake bypass valve further includes a stationary valve core 2, and a sealing sleeve 3 abuts against or is connected to the stationary valve core 2. When the moving valve core 4 moves toward the stationary valve core 2, it drives the sealing cap 5 to open the passage of the intake bypass valve.

[0079] Understandably, by setting the sealing sleeve 3 to abut or connect to the stationary valve core 2, the structure of the intake bypass valve is made compact, which helps to reduce the overall size of the intake bypass valve in the moving direction of the moving valve core 4, and realizes the miniaturization design of the intake bypass valve.

[0080] Specifically, refer to Figure 3 The stationary valve core 2 is provided with a receiving groove 2a, and at least a portion of the sealing sleeve 3 is disposed within the receiving groove 2a. By providing a receiving groove 2a on the stationary valve core 2, the sealing sleeve 3 extends into the receiving groove 2a, thus further shortening the overall size of the intake bypass valve in the moving direction of the moving valve core 4, and the receiving groove 2a on the stationary valve core 2 can be used to position and limit the sealing sleeve 3, thereby improving the stability of the sealing sleeve 3.

[0081] Reference Figures 1 to 3 In some embodiments, the intake bypass valve further includes a coil assembly 1, a stationary valve core 2, and an elastic element 6.

[0082] The aforementioned coil assembly 1 includes a bracket 11 and a coil 12 wound around the outside of the bracket 11. When the coil 12 is energized, it drives the valve core 4 to move via electromagnetic force. Preferably, the bracket 11 is cylindrical, which is simple in structure, increases magnetic flux, reduces coil winding, and saves costs. Of course, the bracket 11 can also be other structures, such as a U-shape.

[0083] The aforementioned stationary valve core 2 is at least partially disposed inside the bracket 11, with the closed end of the sealing sleeve relatively close to the stationary valve core. The position of the stationary valve core 2 relative to the bracket 11 remains fixed, meaning that the position of the stationary valve core 2 is fixed during the operation of the intake bypass valve.

[0084] When coil 12 is energized, it drives the moving valve core 4 to move closer to the stationary valve core 2, thereby opening the passage of the sealing cap 5. Meanwhile, the aforementioned elastic element 6 drives the moving valve core 4 to move away from the stationary valve core 2, thereby closing the passage of the intake bypass valve with the sealing cap 5. Thus, when the moving valve core 4 moves closer to the stationary valve core 2, it compresses the elastic element 6. Therefore, when coil 12 is de-energized, the force of the elastic element 6 returning to its original shape pushes the moving valve core 4 away from the stationary valve core 2.

[0085] It should be noted that, referring to Figure 1 The aforementioned moving valve core 4 and stationary valve core 2 are arranged at intervals in the first direction, and the moving valve core 4 reciprocates relative to the stationary valve core 2 in the first direction. The bidirectional arrow X in the diagram represents the first direction.

[0086] Reference Figures 1 to 3 The intake bypass valve also includes a valve body 7 and a valve cover 8 connected to and surrounding an installation cavity. The coil assembly 1, the sealing sleeve 3 and the stationary valve core 2 are all disposed in the installation cavity. The sealing sleeve 3 is sandwiched between the valve cover 8 and the bracket 11, and a sealing element 9 is disposed between the sealing sleeve 3 and the valve cover 8. A through hole 8a is provided on the valve cover 8, and a sealing cap 5 is sealed through the through hole 8a.

[0087] Understandably, the valve body 7 and the valve cover 8 form an installation cavity to install the coil assembly 1, the sealing sleeve 3 and the stationary valve core 2, thereby fixing the coil assembly 1, the stationary valve core 2 and the sealing sleeve 3. The sealing cap 5 seals the through hole 8a on the valve cover 8, so that when the moving valve core 4 drives the sealing cap 5 to move, the sealing cap 5 and the valve cover 8 remain in a sealed state.

[0088] Thus, when the intake bypass valve passage is closed, after coil 12 is energized, the attraction of coil 12 on the moving valve core 4 drives the moving valve core 4 to move closer to the stationary valve core 2. During this process, the moving valve core 4 moves relative to the sealing sleeve 3, the sealing cap 5 moves relative to the valve cover 8, and the elastic element 6 is gradually compressed. When the moving valve core 4 moves to contact the closed end of the sealing sleeve 3, the moving valve core 4 cannot move due to the limitation of the sealing sleeve 3, and the intake bypass valve passage is in the open state.

[0089] When the intake bypass valve is open, and coil 12 is de-energized, the attraction of coil 12 to the moving valve core 4 disappears. Under the action of elastic element 6, the moving valve core 4 moves away from the stationary valve core 2 until the sealing cap 5 closes the passage and can no longer move. The state at this time is as follows: Figure 1 As shown.

[0090] For example, refer to Figures 1 to 3 An intake bypass valve is provided, which includes a coil assembly 1, a stationary valve core 2, a sealing sleeve 3, a moving valve core 4, a sealing cap 5, an elastic element 6, a valve body 7, and a valve cover 8.

[0091] The coil assembly 1 includes a bracket 11 and a coil 12 wound around the outside of the bracket 11. A stationary valve core 2 is partially disposed inside the bracket 11. A sealing sleeve 3 has a receiving cavity 3a, one end of which is open and the other end is closed, with the closed end relatively close to the stationary valve core 2. One end of the aforementioned moving valve core 4 extends into the receiving cavity 3a and can slide relative to the sealing sleeve 3. When the coil 12 is energized, it drives the moving valve core 4 to move towards the stationary valve core 2, thereby opening the channel of the sealing cap 5. The sealing cap 5 is connected to the other end of the moving valve core 4 and partially extends into the receiving cavity 3a through the opening. The sealing cap 5 has a balance hole 5a communicating with the receiving cavity 3a.

[0092] When coil 12 is energized, the attraction of coil 12 to moving valve core 4 drives moving valve core 4 towards stationary valve core 2, thereby causing sealing cap 3 to open the passage of the intake bypass valve, and compressing elastic element 6 in the process. When coil 12 is de-energized, the force of elastic element 6 returning to its original shape drives moving valve core 4 away from stationary valve core 2, thereby causing sealing cap 5 to close the passage of the intake bypass valve.

[0093] The sealing sleeve 3 includes a first sleeve 31 and a second sleeve 32 that are connected to each other. One end of the first sleeve 31 is closed, and one end of the second sleeve 32 is open. The inner diameter of the first sleeve 31 is smaller than the inner diameter of the second sleeve 32. One end of the moving valve core 4 extends into the first sleeve 31, and the sealing cap 5 extends into the second sleeve 32. The first sleeve 31 is provided with an extension edge 311 extending into the second sleeve 32, and the extension edge 311 surrounds the moving valve core 4.

[0094] The sealing sleeve 3 is made of plastic.

[0095] The aforementioned elastic element 6 is sleeved on the moving valve core 4, with one end limited to the sealing cap 5 and the other end limited to the stepped surface formed by the first sleeve 31 and the second sleeve 32.

[0096] The aforementioned static valve core 2 is provided with a receiving groove 2a, and the first sleeve 31 is partially disposed in the receiving groove 2a.

[0097] The valve body 7 and valve cover 8 are connected and enclosed to form an installation cavity. The coil assembly 1, sealing sleeve 3 and static valve core 2 are all set in the installation cavity. The sealing sleeve 3 is sandwiched between the valve cover 8 and the bracket 11, and a sealing element 9 is provided between it and the valve cover 8. A through hole 8a is opened on the valve cover 8, and the sealing cap 5 is sealed through the through hole 8a.
