Description

Technical Field

[0001] This disclosure relates to the field of control valve assembly technology for vehicle thermal management systems, and more particularly to an integrated valve and a vehicle. Background Technology

[0002] Currently, vehicle thermal management integrated modules generally use independent valves assembled into the piping. For example, the refrigerant-side piping of the thermal management integrated module in heat pump vehicles typically requires the use of shut-off valves and check valves. This necessitates multiple piping sections to connect these two types of valves during the design and manufacturing process, increasing system complexity and cost. Furthermore, the existing solutions usually require straight, rigid pipe sections and valve support brackets to improve reliability. This design not only affects the overall vehicle layout but also limits available interior space. Moreover, the piping connection methods in the existing solutions are cumbersome, requiring careful consideration of the installation point orientation and tool space. Additionally, the numerous connection points in the existing solutions increase the risk of external leakage, especially for refrigerant-side piping with high internal pressure, thus reducing system reliability.

[0041] Some embodiments of this disclosure will now be described in detail, examples of which are illustrated in the accompanying drawings. When the following description refers to the drawings, unless otherwise indicated, the same numbers in different drawings denote the same or similar elements. Various changes, modifications, and equivalents of the methods, apparatus, and / or systems described herein will become apparent upon understanding this disclosure. For example, the order of operations described herein is merely illustrative and is not limited to those orders set forth herein, but can be changed as will become apparent upon understanding this disclosure, except for operations that must be performed in a particular order. Furthermore, for clarity and brevity, descriptions of features known in the art may be omitted.

[0042] The embodiments described in the following examples of this disclosure are not representative of all embodiments consistent with this disclosure. Rather, they are merely examples of apparatuses and methods consistent with some aspects of this disclosure as detailed in the appended claims.

[0043] See Figure 1 The diagram illustrates a typical integrated valve structure. In this exemplary embodiment, the integrated valve proposed in this disclosure is described using an application in a vehicle's thermal management system as an example, such as in the agent-side piping of a heat pump vehicle's thermal management system. It will be readily understood by those skilled in the art that various modifications, additions, substitutions, deletions, or other changes may be made to the specific embodiments described below to apply the relevant designs of this disclosure to other application scenarios, and these changes remain within the scope of the principles of the integrated valve proposed in this disclosure.

[0044] like Figure 1 As shown, in one embodiment of this disclosure, the integrated valve includes a valve seat 100, a shut-off valve component 200, and a check valve component 300. (See also...) Figures 2 to 10 , Figure 2 The image shows a representative axial sectional view of the integrated valve. Figure 3 China representatively shows Figure 2 A magnified view of a portion of the image; Figure 4 The image shows a representative three-dimensional sectional view of the integrated valve. Figure 5 and Figure 6 The diagrams show representative exploded views of the integrated valve from two different perspectives. Figure 7 and Figure 8 The diagrams show representative structural schematics of the one-way valve component 300 in the conducting state from two different perspectives.

[0045] Figure 9 and Figure 10 The figures above represent structural schematic diagrams of the one-way valve component 300 in the disconnected state from two different perspectives. The following will, in conjunction with the above figures, provide a detailed description of the structure, connection method, and functional relationship of the main components of the integrated valve proposed in this disclosure.

[0046] like Figures 1 to 4As shown, in one embodiment of this disclosure, the valve seat 100 serves as the main frame in the integrated valve assembly, with the shut-off valve component 200 and the one-way valve component 300 respectively integrated on this main frame. The valve seat 100 includes a valve cavity 101 and a first valve port 102 and a second valve port 103 communicating with the valve cavity 101. A first valve outlet 104 is located within the valve cavity 101, situated between the first valve port 102 and the second valve port 103. The shut-off valve component 200 includes a first valve body 210 connected to the valve seat 100 and a first valve core 220 movably disposed within the first valve body 210. The first valve core 220 partially extends into the valve cavity 101 and is driven by a drive mechanism 230 to close or open the first valve outlet 104. Thus, the shut-off valve component 200 enables the switching control of the integrated valve's conduction and shut-off states. The one-way valve component 300 includes a second valve body 310 disposed within a valve cavity 101 and a second valve core 320 movably disposed within the second valve body 310. The second valve body 310 is located on the side of the first valve port 104 near the second valve hole 103. The second valve body 310 is provided with a flow channel 3101 and a second valve port 3102 communicating with the flow channel 3101. The second valve core 320 opens the second valve port 3102 when the medium flows from the first valve hole 102 to the second valve hole 103, or closes the second valve port 3102 when the medium flows from the second valve hole 103 to the first valve hole 102. That is, the one-way valve component 300 can realize a one-way flow function, and the flow direction is from the first valve hole 102 to the second valve hole 103. Through the above structural design, the integrated valve proposed in this disclosure has a high degree of integration, which can reduce the number of pipelines and reduce system complexity and cost.

[0047] It should be noted that, compared to existing solutions that connect multiple valves individually to pipelines (hereinafter referred to as existing non-integrated solutions), this disclosure eliminates the need for straight sections of rigid pipe in the pipeline, and avoids the need for valve matching brackets or other structures to improve reliability, thereby reducing the impact on the overall vehicle layout and freeing up more interior space. Furthermore, this disclosure avoids the cumbersome process of connecting multiple valves to pipelines in existing non-integrated solutions, reducing the requirements for the orientation of installation points and tool space. Moreover, compared to existing non-integrated solutions, this disclosure reduces the number of connection points, especially when applied to agent-side pipelines with high internal pressure. By reducing the number of connection points, this disclosure reduces the risk of external leakage and improves system reliability. Furthermore, in existing non-integrated solutions, for pipelines that simultaneously install a shut-off valve and a check valve, a certain length of pipeline needs to be connected between these two valve components. In contrast, this disclosure adopts an embedded integrated design, that is, using the valve seat 100 to connect the shut-off valve component 200 and the check valve component 300, which can significantly shorten the distance between the two valve components, thereby significantly reducing the internal flow resistance of the integrated valve seat in the pipeline (e.g., the agent-side pipeline).

[0048] like Figure 1 , Figure 2 , Figures 4 to 6 As shown, in one embodiment of this disclosure, the shut-off valve component 200 can be connected to one end of the valve seat 100 in a first direction, and the first valve port 102 can be located at the other end of the valve seat 100 in the first direction. This first direction can be referred to as direction D1 shown in the figures, and can also be understood as the axial direction of the integrated valve, or the direction of movement of the first valve core 220 when opening and closing the first valve port 104. Based on this, the first valve port 102 can be located on one side of the valve seat 100 in a second direction perpendicular to the first direction, which can be referred to as direction D2 shown in the figures.

[0049] like Figure 1 and Figure 2 As shown, in one embodiment of this disclosure, the valve seat 100 may be provided with a first connecting flange 110 on the side where the first valve hole 102 is provided (e.g., on the side of the valve seat 100 in the second direction). For example, the side of the valve seat 100 may be provided with an interface 130 for arranging the first valve hole 102, and the end face of the interface 130 away from the valve seat 100 may serve as the flange face of the first connecting flange 110. Accordingly, the integrated valve can be connected to the pipeline via the first connecting flange 110 through a connector (e.g., but not limited to bolts). Through the above structural design, this disclosure can utilize the first connecting flange 110 to connect the pipeline, such as the refrigerant-side pipeline, so that the first valve hole 102 can serve as the refrigerant-side inlet, making the connection convenient and reliable. In addition, this disclosure can utilize the interface 130 to reserve installation depth when the first valve hole 102 is connected to the pipeline (e.g., when the first valve hole 102 serves as the refrigerant inlet of the refrigerant-side pipeline), facilitating the installation of the integrated valve in the pipeline.

[0050] like Figure 2 and Figure 4 As shown, in one embodiment of this disclosure, a second connecting flange 120 may be provided at one end of the valve seat 100 where the second valve hole 103 is provided (e.g., one side of the valve seat 100 in the first direction). For example, the end face of the valve seat 100 away from the shut-off valve component 200 in the first direction may serve as the flange face of the second connecting flange 120. Accordingly, the integrated valve can be connected to a pipeline via the second connecting flange 120 using a connector (e.g., but not limited to bolts). Through the above structural design, this disclosure enables the connection of pipelines, such as refrigerant-side pipelines, using the second connecting flange 120, so that the second valve hole 103 serves as the outlet on the refrigerant side, making the connection convenient and reliable.

[0051] like Figure 2 , Figure 5 and Figure 6As shown, in one embodiment of this disclosure, the valve seat 100 is provided with a mounting hole 105, which connects to the end of the valve cavity 101 away from the second valve hole 103. Based on this, a shut-off valve component 200 can be disposed at the end of the valve seat 100 away from the second valve hole 103, a first valve body 210 can be connected to the mounting hole 105, and a first valve core 220 extends to the side of the first valve port 104 near the mounting hole 105. A first sealing element 211, such as, but not limited to, a sealing ring, can be provided between the first valve body 210 and the mounting hole 105 to ensure the sealing performance between the first valve body 210 and the valve seat 100.

[0052] Based on the structural design of the first valve body 210 connected to the mounting hole 105, in one embodiment of this disclosure, the outer periphery of the first valve body 210 may be provided with external threads, and the wall of the mounting hole 105 may be provided with internal threads that mate with the external threads. The first valve body 210 and the mounting hole 105 are connected via threaded engagement. Through the above structural design, this disclosure can reduce the assembly difficulty of the first valve body 210 and the valve seat 100, and realize convenient and labor-saving disassembly and assembly of the shut-off valve component 200 and the valve seat 100, facilitating the maintenance or replacement of the shut-off valve component 200. In other embodiments of this disclosure, the first valve body 210 and the valve seat 100 may also be connected in other ways, such as welding, connecting with connectors, snap-fitting, crimping, etc., and are not limited to this embodiment.

[0053] like Figure 2 and Figure 4 As shown, in one embodiment of this disclosure, the shut-off valve component 200 may further include an elastic element 240 located between the first valve core 220 and the valve cavity 101. For example, the valve cavity 101 may be provided with a stop surface facing the mounting hole 105, the stop surface being provided, for example, around the first valve port 104, and one end of the elastic element 240 is limited by the stop surface. Through the above structural design, this disclosure can utilize the elastic element 240 to achieve the elastic reset of the first valve core 220. For example, after the first valve core 220 loses the driving force applied by the driving mechanism 230 toward the first valve port 104 (i.e., the driving force to close the first valve port 104), the first valve core 220 can return to its initial position under the drive of the elastic restoring force of the elastic element 240, thereby realizing the opening of the first valve port 104.

[0054] like Figure 3 As shown, in one embodiment of this disclosure, the cavity wall of the valve cavity 101 located between the first valve port 104 and the second valve hole 103 may be provided with a mounting groove 106. The second valve body 310 may be partially accommodated in the mounting groove 106. A second sealing element 311, such as, but not limited to, a sealing ring, may be provided between the second valve body 310 and the mounting groove 106 to ensure the sealing performance between the second valve body 310 and the valve seat 100.

[0055] like Figure 3 As shown, based on the structural design of the second valve body 310 being accommodated in the mounting groove 106, in one embodiment of this disclosure, the valve cavity 101 located between the first valve port 104 and the second valve hole 103 may have a first part 1011 and a second part 1012. The first part 1011 connects to the first valve port 104, and the second part 1012 connects the first part 1011 and the second valve hole 103. The inner diameter of the second part 1012 is larger than the inner diameter of the first part 1011. The mounting groove 106 is formed at the connection between the first part 1011 and the second part 1012. Through the above structural design, this disclosure utilizes a variable diameter design in a portion of the valve cavity 101 to form the mounting groove 106 for the one-way valve component 300, resulting in a simple structure that is easy to implement. Furthermore, since the inner diameter of the second part 1012 is relatively large, this disclosure can utilize the stepped surface (i.e., the bottom of the mounting groove 106) at the connection between the second part 1012 and the first part 1011 to limit and stop the second valve body 310. That is, the outer diameter of the one-way valve component 300 (the outer diameter of the second valve body 310) is larger than the inner diameter of the first part 1011. Accordingly, when assembling the one-way valve component 300, the one-way valve component 300 can be inserted into the valve cavity 101 through the second valve hole 103, and then moved towards the first valve port 104 until the second valve body 310 abuts against the aforementioned stepped surface, thereby reducing the assembly difficulty and improving the assembly efficiency.

[0056] like Figure 3 As shown, based on the structural design of the second valve body 310 being accommodated in the mounting groove 106, in one embodiment of this disclosure, the second valve body 310 can be fixed to the mounting groove 106 via a limiting snap ring 330. The limiting snap ring 330 is located at the end of the second valve body 310 away from the first valve port 104, and the limiting snap ring 330 engages with the slot 107 provided in the cavity wall of the second part 1012. Thus, the second valve body 310 is pressed against the stepped surface by the limiting snap ring 330, thereby fixing the second valve body 310 to the valve seat 100. Through the above structural design, this disclosure can improve the assembly stability and reliability of the second valve body 310 and the valve seat 100, and achieve convenient and labor-saving disassembly and assembly of the one-way valve component 300 and the valve seat 100. In other embodiments of this disclosure, the second valve body 310 and the valve seat 100 can also be connected in other ways, such as welding, connecting parts, threaded connections, snap-fitting, etc., and are not limited to this embodiment.

[0057] like Figure 2 and Figure 4As shown, in one embodiment of this disclosure, the one-way valve component 300 and the second valve hole 103 are arranged at intervals, such that the portion of the valve chamber 101 located between the one-way valve component 300 and the second valve hole 103 forms a reserved mounting portion 108. Through the above structural design, this disclosure can reserve an installation depth when the second valve hole 103 is connected to a pipeline (e.g., when the second valve hole 103 is used as a refrigerant outlet connector side pipeline), facilitating the installation of the integrated valve in the pipeline.

[0058] like Figure 3 As shown in one embodiment of this disclosure, the structure of the one-way valve component 300 is specifically exemplified as follows: The second valve body 310 is generally a cylindrical structure, and the cavity of the cylindrical structure is the flow channel 3101 of the second valve body 310. The flow channel 3101 is used to enable the two parts of the valve cavity 101 located on both sides of the one-way valve component 300 to be connected when the second valve core 320 opens the second valve port 3102, thereby enabling the first valve hole 102 and the second valve hole 103 to be connected when the first valve core 220 opens the first valve port 104. The second valve body 310 is provided with a guide portion 312 located in the flow channel 3101, and the guide portion 312 only connects to a portion of the inner wall of the flow channel 3101 and does not completely block the flow channel 3101. The guide portion 312 is provided with a guide hole. The second valve core 320 includes a valve stem 321 passing through a guide hole and a sealing structure 322 and a limiting part 323 disposed on the valve stem. The sealing structure 322 and the limiting part 323 are respectively located on both sides of the guide part 312. The sealing structure 322 is used to seal the second valve port 3102 to achieve the closure of the second valve port 3102. The limiting part 323 is used to limit the position of the valve stem 321 and the guide part 312. That is, when the second valve port 3102 is open, the limiting part 323 restricts the relative position of the second valve core 320 and the second valve body 310 (or the second valve port 3102) and prevents the second valve core 320 from detaching.

[0059] In one embodiment of this disclosure, the one-way valve component 300 may further include an elastic element (not shown in the figures) located between the second valve core 320 and the second valve body 310. For example, the elastic element may be located between the limiting portion 323 and the guide portion 312. Through the above structural design, this disclosure can utilize the elastic element to achieve the elastic reset of the second valve core 320, so that the one-way valve component 300 remains in a one-way closed state.

[0060] In one embodiment of this disclosure, the valve seat 100 may be made of aluminum, and more particularly of 6-series aluminum.

[0061] In one embodiment of this disclosure, the valve seat 100 can be manufactured by means of profiles or forged blanks and further machining.

[0062] It should be noted that the integrated valves shown in the accompanying drawings and described in this specification are merely a few examples among many integrated valves capable of employing the principles of this disclosure. It should be clearly understood that the principles of this disclosure are by no means limited to any detail or component of the integrated valves shown in the accompanying drawings or described in this specification.

[0063] Based on the above detailed description of several exemplary embodiments of the integrated valve proposed in this disclosure, an exemplary embodiment of the vehicle proposed in this disclosure will be described below.

[0064] In one embodiment of this disclosure, the vehicle proposed in this disclosure includes the integrated valve proposed in this disclosure and described in detail in the above embodiments. For example, the vehicle is a heat pump model, which includes a thermal management system, and the thermal management system may specifically be provided with a refrigerant-side pipeline, which is provided with the integrated valve proposed in this disclosure, so that the refrigerant-side pipeline can respectively realize the pipeline functions of interception and unidirectional flow.

[0065] In one embodiment of this disclosure, the vehicle proposed in this disclosure can be a hybrid vehicle, a non-hybrid vehicle, an electric vehicle, a fuel cell vehicle, or other types of vehicles. The vehicle can be an autonomous vehicle, a semi-autonomous vehicle, or a non-autonomous vehicle.

It should be clearly understood that the principles of this disclosure are by no means limited to any detail or component of the vehicles shown in the accompanying drawings or described in this specification.

[0067] In summary, the integrated valve proposed in this disclosure includes a valve seat 100, a shut-off valve component 200, and a check valve component 300. The shut-off valve component 200 and the check valve component 300 respectively realize the shut-off function and the one-way flow function of the integrated valve. Specifically, the first valve body 210 of the shut-off valve component 200 and the second valve body 310 of the check valve component 300 are respectively disposed on the valve seat 100, realizing the integrated assembly of the two valve components, that is, providing an embedded solution for the shut-off valve component 200 and the check valve component 300 in the valve seat 100. Through the above structural design, the integrated valve proposed in this disclosure has a high degree of integration, which can reduce the number of pipelines, reduce system complexity and cost.

[0070] Other embodiments of this disclosure will readily occur to those skilled in the art upon consideration of the specification and practice of the invention disclosed herein. This application is intended to cover any variations, uses, or adaptations of this disclosure that follow the general principles of this disclosure and include common knowledge or customary techniques in the art not disclosed herein. The specification and examples are to be considered exemplary only, and the true scope and spirit of this disclosure are indicated by the following claims.

[0071] It should be understood that, unless otherwise expressly specified and limited, the terms "installation," "connection," "linking," "fixing," etc., used in the embodiments of this disclosure should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection, an electrical connection, or a connection that allows communication between them; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components, unless otherwise expressly limited. Those skilled in the art can understand the specific meaning of the above terms herein according to the specific circumstances.

[0072] Although terms such as “first” and “second” may be used herein to describe various components, parts, regions, layers, or sections, these components, parts, regions, layers, or sections are not limited to these terms. Rather, these terms are used only to distinguish one component, part, region, layer, or section from another. Therefore, without departing from the teachings of the examples described herein, the first component, part, region, layer, or section mentioned in the examples may also be referred to as the second component, part, region, layer, or section. Furthermore, the terms “first” and “second” are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, a feature defined as “first” or “second” may explicitly or implicitly include at least one of that feature. In the description herein, “a plurality” means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0073] It should be understood that spatial relative terms, such as “above,” “upper,” “below,” and “lower,” are used herein to describe the relationship between one element and another shown in the figures. In addition to the orientation depicted in the figures, these spatial relative terms are also intended to encompass different orientations of the device in use or operation. For example, if the device in the figures is flipped, an element described as “above” or “upper” relative to another element would be “below” or “lower” relative to that other element. Thus, depending on the spatial orientation of the device, the term “above” encompasses both above and below orientations. Devices may have other orientations (e.g., rotated 90 degrees or in other orientations), and the spatial relative terms used herein should be interpreted accordingly.

[0074] It should be understood that this disclosure is not limited to the precise structures described above and shown in the accompanying drawings, and various modifications and changes can be made without departing from its scope. The scope of this disclosure is limited only by the appended claims.
