Description

Technical Field

[0001] This application relates to the field of vehicle component technology, and more particularly to a two-way connector, a piping system, and a vehicle. Background Technology

[0002] In cooling systems, the application of check valves is crucial. Their main function is to ensure the unidirectional flow of the cooling medium and prevent backflow.

[0003] Existing check valve designs typically mount the valve directly inside the rubber tube, which can easily lead to the check valve sliding inside the rubber tube. This prevents the cooling medium from flowing unidirectionally at the preset position within the cooling system, thus affecting the cooling effect of the cooling system. Utility Model Content

[0004] In view of this, this application provides a two-way connector, a pipeline system and a vehicle. By making the inner diameter of the movable cavity larger than the inner diameter of the flow channel to form a stepped structure, when the two-way connector is connected to the pipeline system, the valve core will not detach from the movable cavity due to the blocking effect of the stepped structure, which helps to improve the reliability of the one-way conduction function of the two-way connector.

[0005] In a first aspect, this application provides a two-way connector, comprising: a connector body, wherein the inner side of the connector body is provided with a movable cavity and two flow channels located on both sides of the movable cavity, the inner diameter of the movable cavity is larger than the inner diameter of at least one of the two flow channels; a valve core disposed in the movable cavity, wherein there is a gap between the valve core and the inner wall of the movable cavity, and the valve core is movable between a first position and a second position, wherein, in the first position, the valve core blocks the one of the two flow channels whose inner diameter is smaller than the inner diameter of the movable cavity; and in the second position, the valve core is spaced apart from the one of the two flow channels whose inner diameter is smaller than the inner diameter of the movable cavity, so that the two sides of the valve core are connected.

[0006] The two-way connector of this application features a stepped structure because the inner diameter of the movable cavity is larger than the inner diameter of the flow channel. When the two-way connector is connected to the piping system, during normal operation of the vehicle equipped with the connector, the cooling medium flows normally, pushing the valve core to the second position, allowing the cooling system to be open at the preset position. When the cooling medium flows in the reverse direction, it pushes the valve core to the first position, causing the valve core to block the movable cavity and forming a one-way flow structure. During the sliding process of the valve core, the stepped structure formed at the connection between the movable cavity and the flow channel limits the sliding of the valve core, preventing it from coming out of the flow channel. This improves the reliability of the one-way flow function of the two-way connector, thereby ensuring the normal operation of the cooling system of the vehicle equipped with the two-way connector of this application.

[0007] In some embodiments, the inner wall of the movable cavity is provided with a guide structure extending along its own axial direction, and the peripheral wall of the valve core is provided with a guide engagement structure. The valve core and the connector body are slidably engaged through the guide structure and the guide engagement structure.

[0008] Thus, through the sliding fit between the guide structure and the guide mating structure, the valve core can move precisely between the first position and the second position, ensuring that the flow channel is completely blocked in the first position and that the fluid can flow smoothly in the second position.

[0009] According to some embodiments of this application, one of the guide structure and the guide mating structure is formed as a guide groove, and the other is formed as a guide protrusion.

[0010] The guide protrusion extends into the guide groove, and the relative sliding between the guide protrusion and the guide groove helps to avoid the rotation or tilting of the valve core during movement, ensuring the precise positioning of the valve core between the first and second positions. This improves the movement accuracy of the valve core and the sealing performance of the joint, and reduces the failure of the two-way joint due to improper valve core positioning.

[0011] According to some embodiments of this application, a fitting gap is provided between the guide groove and the guide protrusion, the width of which is 0.1mm-0.4mm; and / or,

[0012] The guide groove has a radial depth of 1mm-2mm along the movable cavity.

[0013] This ensures that the guide groove has a suitable depth and that there is a suitable clearance between the guide groove and the guide protrusion. This helps to ensure that the guide groove has a good guiding effect and that the valve core has a sufficient sealing effect, so as to guarantee the one-way conduction effect of the two-way connector.

[0014] According to some embodiments of this application, the outer wall of the valve core and the inner wall of the movable cavity are spaced apart to form a flow gap, and when the valve core is in the second position, the portions of the movable cavity located on both sides of the valve core are connected through the flow gap.

[0015] When the valve spool moves to the second position, the flow clearance provides a fluid passage, allowing fluid to bypass the valve spool and flow between the two sides of the moving chamber. This design ensures smooth fluid flow without obstruction by the valve spool when fluid connectivity is required.

[0016] According to some embodiments of this application, the width of the flow gap is 0.5mm-1mm.

[0017] On the one hand, the width of the flow gap ranges from 0.5mm to 1mm, providing sufficient space to allow fluid to flow freely between the two sides of the moving chamber. On the other hand, by precisely controlling the width of the flow gap, while ensuring fluid flow, problems such as poor sealing between the valve core and the moving chamber or flow runaway that may be caused by an excessively large gap are avoided. This improves the functional flexibility and reliability of the two-way connector, enabling it to provide stable unidirectional performance under various operating conditions.

[0018] According to some embodiments of this application, the inner diameters of both flow channels are smaller than the inner diameter of the movable cavity, and the projections of both flow channels onto the reference plane are both located inside the projection of the movable cavity onto the reference plane, wherein the reference plane is perpendicular to the axial direction of the movable cavity.

[0019] This design helps ensure the valve core slides between the first and second positions, preventing it from detaching from the moving cavity and improving the structural reliability of the two-way connector. Simultaneously, the projection of the flow channel is located inside the projection of the moving cavity, further ensuring that the inner diameter of the flow channel is smaller than the inner diameter of the moving cavity. This allows for better control of the valve core's sealing performance and reduces the likelihood of one-way flow failure in the two-way connector.

[0020] According to some embodiments of this application, the two flow channels are an inlet flow channel and an outlet flow channel, and the guide structure is spaced apart from the outlet flow channel at one end facing the outlet flow channel.

[0021] The spacing design between the guide structure and the outlet channel ensures that the cooling medium is not disturbed by the guide structure when flowing in the outlet channel, thus maintaining the smoothness and stability of the cooling medium flow in the pipeline system.

[0022] Secondly, this application also provides a pipeline system, including: a first unit to be connected and a second unit to be connected; the aforementioned two-way connector, wherein the first unit to be connected and the second unit to be connected are respectively connected to two flow channels of the two-way connector.

[0023] The pipeline system of this application uses the aforementioned two-way connector, in which the inner diameter of the movable cavity is larger than the inner diameter of the flow channel, forming a stepped structure. When the two-way connector is connected to the pipeline system, the valve core will not detach from the movable cavity due to the blocking effect of the stepped structure, which helps to improve the reliability of the one-way conduction function of the two-way connector.

[0024] Thirdly, this application also provides a vehicle including the aforementioned piping system.

[0025] The vehicle described in this application, due to the use of the aforementioned piping system, has good unidirectional conduction of the two-way connectors of the piping system, which is beneficial to the long-term stable operation of the vehicle's cooling system equipped with the aforementioned piping system.

[0039] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the specific technical solutions of this application will be further described in detail below with reference to the accompanying drawings of the embodiments of this application. The following embodiments are used to illustrate this application, but are not intended to limit the scope of this application.

[0040] In the embodiments of this application, 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. Therefore, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of the embodiments of this application, unless otherwise stated, "multiple" means two or more.

[0041] Furthermore, in the embodiments of this application, directional terms such as "upper," "lower," "left," and "right" are defined relative to the orientation of the components shown in the accompanying drawings. It should be understood that these directional terms are relative concepts, used for relative description and clarification, and can change accordingly depending on the orientation of the components in the accompanying drawings.

[0042] In the embodiments of this application, unless otherwise explicitly specified and limited, the term "connection" should be interpreted broadly. For example, "connection" can mean a fixed connection, a detachable connection, or an integral part; it can mean a direct connection or an indirect connection through an intermediate medium.

[0043] In embodiments of this application, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus.

[0044] In the embodiments of this application, the terms "exemplary" or "for example" are used to indicate that something is an example, illustration, or description.

Specifically, the use of the terms "exemplary" or "for example" is intended to present the relevant concepts in a specific manner.

[0045] Existing check valve designs typically mount the valve directly inside the rubber tube, which can easily lead to the check valve sliding inside the rubber tube. This prevents the cooling medium from flowing unidirectionally at the preset position within the cooling system, thus affecting the cooling effect of the cooling system.

[0046] In view of this, the present application provides a two-way connector 100, a pipeline system and a vehicle. By making the inner diameter of the movable cavity 111 larger than the inner diameter of the flow channel 112, a stepped structure is formed. When the two-way connector 100 is connected to the pipeline system, the valve core 120 will not detach from the movable cavity 111 due to the blocking effect of the stepped structure, which helps to improve the reliability of the one-way conduction function of the two-way connector 100.

[0047] refer to Figures 1 to 8 In one aspect, embodiments of this application provide a two-way connector 100, which may include a connector body 110 and a valve core 120.

[0048] refer to Figure 1 , Figure 2 , Figure 3 and Figure 4 The inner side of the connector body 110 is provided with a movable cavity 111 and two flow channels 112 located on both sides of the movable cavity 111. The inner diameter of the movable cavity 111 is larger than the inner diameter of at least one of the two flow channels 112. For example, the inner diameter of the movable cavity 111 can be larger than the inner diameter of one flow channel 112, or the inner diameter of the movable cavity 111 can be larger than the inner diameter of both flow channels 112 at the same time. In this way, by differentiating the inner diameter of the movable cavity 111 from the inner diameter of the flow channel 112, a stepped limiting structure is formed at the connection between the movable cavity 111 and the flow channel 112. The stepped limiting structure prevents the valve core 120 from coming out of the movable cavity 111, which helps to improve the structural reliability of the two-way connector 100.

[0049] It should be noted that when the inner diameter of the active cavity 111 is only larger than the inner diameter of one flow channel 112, and the cooling medium in the two-way connector 100 has a tendency to flow in the opposite direction, the valve core 120 blocks the flow channel 112 with the smaller inner diameter to ensure the sealing effect between the valve core 120 and the connector body 110.

[0050] refer to Figure 3 The valve core 120 is located in the movable cavity 111, and there is a gap between the valve core 120 and the inner wall of the movable cavity 111. Thus, when the two-way connector 100 is connected to the pipeline system, and the two-way connector 100 is unidirectionally open, the two flow channels 112 can be connected through the gap.

[0051] refer to Figure 2 , Figure 7 and Figure 8 The valve core 120 is movable between a first position and a second position. In the first position, the valve core 120 blocks the one of the two flow channels 112 whose inner diameter is smaller than the inner diameter of the movable cavity 111. (Refer to...) Figure 7When the cooling medium in the pipeline system connected to the two-way connector 100 exhibits a flow trend opposite to the preset flow direction (i.e., reverse flow), the valve core 120, driven by the cooling medium, moves to the first position, blocking one of the two flow channels 112. At this time, the connection between the two flow channels 112 is broken, thus blocking the reverse flow of the two-way connector 100. Specifically, when the valve core 120 is in the first position, it blocks one of the flow channels 112. This can be achieved by the valve core 120 having a blocking portion protruding towards the flow channel 112, the diameter of which matches the inner diameter of the flow channel 112. When the valve core 120 is in the first position, the blocking portion is inserted into the corresponding flow channel 112, thereby blocking that flow channel 112. Alternatively, the valve core 120 may have a sealing surface on the side facing the corresponding flow channel 112. When the valve core 120 moves to the first position, the sealing surface seals with the aforementioned stepped limiting structure, thereby blocking the flow channel 112, preventing the two-way connector 100 from conducting in reverse, and improving the structural reliability of the two-way connector 100.

[0052] refer to Figure 8 In the second position, the valve core 120 is separated from the one of the two flow channels 112 whose inner diameter is smaller than that of the movable cavity 111, so that the two sides of the valve core 120 are connected. In other words, when the cooling medium in the two-way connector 100 is flowing normally, the cooling medium flowing in the preset flow direction pushes the valve core 120 away from the first position. At this time, the blocked flow channel 112 is connected to the movable cavity 111, and is connected to the other flow channel 112 through the gap between the valve core 120 and the inner wall of the movable cavity 111, so as to realize the unidirectional conduction function of the two-way connector 100.

[0053] The two-way connector 100 of this application embodiment has a stepped structure because the inner diameter of the movable cavity 111 is larger than the inner diameter of the flow channel 112. When the two-way connector 100 is connected to the pipeline system, during normal operation of the vehicle equipped with the two-way connector 100, the cooling medium flows normally, pushing the valve core 120 to the second position, and the cooling system can be opened at the preset position. When the cooling medium flows in the reverse direction, it pushes the valve core 120 to the first position, causing the valve core 120 to block the movable cavity 111, forming a one-way flow structure. During the sliding process of the valve core 120, the stepped structure formed at the connection between the movable cavity 111 and the flow channel 112 limits the sliding of the valve core 120, preventing the valve core 120 from coming out of the flow channel 112. This helps to improve the reliability of the one-way flow function of the two-way connector 100, thereby ensuring the normal operation of the cooling system of the vehicle equipped with the two-way connector 100.

[0054] In some embodiments, the corresponding portion of the movable cavity 111 of the connector body 110 may have a first outer diameter, and the two flow channels 112 may have a second outer diameter and a third outer diameter, respectively. To improve the installation stability of the two-way connector 100, the first outer diameter may exceed the second and third outer diameters, forming a stepped installation structure on both sides of the corresponding portion of the movable cavity 111 of the connector body 110. Simultaneously, the second and third outer diameters can be designed differently, for example, the second outer diameter may exceed the third outer diameter, or the second outer diameter may be smaller than the third outer diameter. The smaller outer diameter corresponds to the flow channel 112 corresponding to the outflow direction of the cooling medium in the two-way connector 100. The unidirectional flow direction of the two-way connector 100 is indicated by its external dimensions, which helps to avoid reverse installation of the two-way connector 100, thereby improving the installation reliability of the two-way connector 100.

[0055] refer to Figure 1 Furthermore, the connector body 110 may be provided with a guide mark. For example, the guide mark may be an arrow indicating a unidirectional conduction direction (see reference). Figure 1 Alternatively, the directional markings can be text labels (such as "in" and "out"). By setting directional markings, the installation reliability of the two-way connector 100 can be further improved, avoiding the need to disassemble and reinstall the two-way connector 100 after the pipeline system is assembled, which is conducive to improving production efficiency.

[0056] refer to Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6 In some embodiments, the inner wall of the movable cavity 111 is provided with a guide structure 1111 extending along its own axial direction, and the peripheral wall of the valve core 120 is provided with a guide mating structure 121. The valve core 120 and the connector body 110 are slidably mated through the guide structure 1111 and the guide mating structure 121. For example, the guide structure 1111 can be a guide groove, a guide slider, a guide rod, etc. Correspondingly, the guide mating structure 121 can be a mating block, a mating groove, a mating sleeve, etc. The mating block slides along the guide groove to achieve a sliding fit between the valve core 120 and the connector body 110, or the mating groove and the guide slider slide relative to each other to achieve a sliding fit between the valve core 120 and the connector body 110, or the mating sleeve sleeved on the guide rod slides along the guide rod to achieve a sliding fit between the valve core 120 and the connector body 110.

[0057] Thus, through the sliding fit between the guide structure 1111 and the guide mating structure 121, the valve core 120 can move precisely between the first position and the second position, ensuring that the flow channel 112 can be completely blocked in the first position, while the smooth flow of fluid can be achieved in the second position.

[0058] Continue to refer to Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6 According to some embodiments of this application, one of the guide structure 1111 and the guide mating structure 121 is formed as a guide groove 1111a, and the other is formed as a guide protrusion 1211. Exemplarily, the guide structure 1111 can be a guide groove 1111a, and the guide mating structure 121 can be a guide protrusion 1211; alternatively, the guide structure 1111 can also be formed as a guide protrusion 1211, and the guide mating structure 121 can be formed as a guide groove 1111a. By extending the guide protrusion 1211 into the guide groove 1111a, and allowing relative sliding between the guide protrusion 1211 and the guide groove 1111a, it is beneficial to avoid rotation or tilting of the valve core 120 during movement, ensuring precise positioning of the valve core 120 between the first and second positions. This improves the movement accuracy of the valve core 120 and the sealing performance of the joint, reducing the possibility of functional failure of the two-way connector 100 due to improper positioning of the valve core 120.

[0059] According to some embodiments of this application, there is a fitting gap between the guide groove 1111a and the guide protrusion 1211. The width of the fitting gap is 0.1mm-0.4mm. For example, the width of the fitting gap can be 0.1mm, 0.2mm, 0.3mm or 0.4mm. Of course, the width of the fitting gap can also be other values. Designers can choose according to their needs. This application does not limit this.

[0060] On the one hand, it is important to avoid an excessively small fit clearance (e.g., less than 0.1 mm), which would result in excessive friction between the guide groove 1111a and the guide protrusion 1211, leading to severe wear between the valve core 120 and the connector body 110, and consequently reducing the service life of the two-way connector 100. On the other hand, it is also important to avoid an excessively large fit clearance (e.g., exceeding 0.4 mm), which would make the valve core 120 prone to wobbling and instability during its movement between the first and second positions. Furthermore, an excessively large fit clearance between the guide groove 1111a and the guide protrusion 1211 could also reduce the sealing performance of the valve core 120 in the first position, causing the cooling medium to flow out in the reverse direction through the fit clearance.

[0061] The radial depth of the guide groove 1111a along the movable cavity 111 is 1mm-2mm. For example, the radial depth of the guide groove 1111a along the movable cavity 111 can be 1mm, 1.2mm, 1.4mm, 1.6mm, 1.8mm, or 2mm. Of course, the radial depth of the guide groove 1111a along the movable cavity 111 can also be other values, and designers can choose according to their needs. This application does not limit this.

[0062] On the one hand, it is important to avoid the radial depth of the guide groove 1111a being too shallow (e.g., less than 1mm). In this case, the mating area between the guide groove 1111a and the guide protrusion 1211 is small, resulting in poor guiding effect and affecting the stability of the valve core 120 during movement. On the other hand, it is also important to avoid the radial depth of the guide groove 1111a being too shallow (e.g., exceeding 2mm). In this case, the thinning of the inner wall of the portion corresponding to the movable cavity 111 by the guide groove 1111a is large, affecting the structural strength of the connector body 110. Simultaneously, due to the large mating dimension of the guide protrusion 1211, its excessive protrusion size makes it prone to breakage at the connection point with the valve core 120, affecting the service life of the two-way connector 100.

[0063] In this embodiment, the guide groove 1111a has a suitable depth dimension, and the guide groove 1111a and the guide protrusion 1211 have a suitable fitting gap, which is beneficial to ensure that the guide groove 1111a has a good guiding effect and ensure that the valve core 120 has a sufficient sealing effect, so as to guarantee the one-way conduction effect of the two-way connector 100.

[0064] refer to Figure 3 and Figure 7 According to some embodiments of this application, the outer wall of the valve core 120 and the inner wall of the movable cavity 111 are spaced apart to form a flow gap 130. When the valve core 120 is in the second position, the portions of the movable cavity 111 located on both sides of the valve core 120 are connected through the flow gap 130. When the valve core 120 moves to the second position, the flow gap 130 provides a fluid passage, allowing fluid to bypass the valve core 120 and flow between the two sides of the movable cavity 111. This design ensures smooth fluid flow without obstruction by the valve core 120 when the two-way connector 100 needs to be connected.

[0065] According to some embodiments of this application, the width of the flow gap 130 is 0.5mm-1mm. For example, the width of the flow gap 130 can be 0.5mm, 0.6mm, 0.7mm, 0.8mm, 0.9mm, or 1mm. Of course, the width of the flow gap 130 can also be other values, and designers can choose according to their needs. This application does not limit this.

[0066] On the one hand, the width of the flow gap 130 ranges from 0.5 mm to 1 mm, providing sufficient space to allow fluid to flow freely between the two sides of the movable chamber 111. On the other hand, by precisely controlling the width of the flow gap 130, while ensuring fluid flow, problems such as poor sealing between the valve core 120 and the movable chamber 111 or flow runaway that may be caused by an excessively large gap are avoided. This improves the functional flexibility and reliability of the two-way connector 100, enabling it to provide stable unidirectional performance under various operating conditions.

[0067] refer to Figure 2 , Figure 7 and Figure 8 According to some embodiments of this application, the inner diameters of the two flow channels 112 are both smaller than the inner diameter of the movable cavity 111. This helps to ensure that the valve core 120 slides between the first position and the second position, avoids the valve core 120 from falling out of the movable cavity 111, and improves the structural reliability of the two-way connector 100.

[0068] The projections of both flow channels 112 onto the reference plane are both located inside the projection of the movable cavity 111 onto the reference plane, and the reference plane is perpendicular to the axial direction of the movable cavity 111. The fact that the projection of the flow channel 112 is located inside the projection of the movable cavity 111 helps to further ensure that the inner diameter of the flow channel 112 is smaller than the inner diameter of the movable cavity 111, thereby better controlling the sealing performance of the valve core 120 and reducing the possibility of unidirectional flow failure in the two-way connector 100.

[0069] Continue to refer to Figure 2 , Figure 7 and Figure 8 According to some embodiments of this application, the two flow channels 112 can be respectively an inlet flow channel 1121 and an outlet flow channel 1122. The guide structure 1111 is spaced apart from the outlet flow channel 1122 at one end. In other words, during the sliding process of the valve core 120 between the first position and the second position, when it slides to the first position, the valve core 120 blocks the inlet flow channel 1121 (see reference). Figure 6 When slid to the second position, the guide structure 1111 on the valve core 120 remains spaced apart from the liquid outlet channel 1122 (refer to...). Figure 7 The cooling medium can flow through the inlet channel 1121 and the flow gap 130 into the gap between the guide structure 1111 and the outlet channel 1122, and then flow out from the outlet channel 1122. Thus, the design of the gap between the guide structure 1111 and the outlet channel 1122 ensures that the cooling medium is not disturbed by the guide structure 1111 when flowing in the outlet channel 1122, thereby maintaining the smoothness and stability of the cooling medium flow within the piping system.

[0070] Secondly, this application also provides a pipeline system, which may include: a first unit to be connected, a second unit to be connected, and the aforementioned two-way connector 100, wherein the first unit to be connected and the second unit to be connected are respectively connected to the two flow channels 112 of the two-way connector 100.

[0071] In the pipeline system of this application embodiment, since the two-way connector 100 described above is used, the inner diameter of the movable cavity 111 is larger than the inner diameter of the flow channel 112, forming a stepped structure. When the two-way connector 100 is connected to the pipeline system, the valve core 120 will not detach from the movable cavity 111 due to the blocking effect of the stepped structure, which helps to improve the reliability of the one-way conduction function of the two-way connector 100.

[0073] It should be noted that the vehicle in this application can refer to large vehicles, small vehicles, etc. For example, according to vehicle type, the vehicle in this application can be a sedan, an off-road vehicle, a multi-purpose vehicle (MPV), or other types of vehicles. Generally, a vehicle is equipped with wheels, a power source, and a transmission system between the wheels and the power source. The transmission system can transmit the power provided by the power source to the wheels, causing the wheels to rotate and thus driving the vehicle.

[0074] It should be noted that the type of power source for the vehicle is not limited in this embodiment. For example, for gasoline vehicles, the power source can refer to a gasoline engine, diesel engine, or other fuel-powered engine; for electric vehicles, the power source can refer to an electric motor; for hybrid vehicles, the power source can refer to either an engine or an electric motor; and for vehicles powered by other means, the power source can refer to any device that generates power.

[0075] In the vehicle of this application embodiment, due to the use of the above-described piping system, the two-way connector 100 of the piping system has good unidirectional conduction function, which is conducive to the long-term stable operation of the vehicle's cooling system with the above-described piping system.
