DETAILED DESCRIPTION

[0018] The features and exemplary embodiments of various aspects of the present invention will be described below. In order to make the purpose, technical solutions and advantages of the present invention more clear, the present invention will be further described below in conjunction with the accompanying drawings and specific embodiments. In this article, relational terms such as "first" and "second" are only used to distinguish one component with the same name from another, and do not necessarily require or imply any such actual relationship or order between these components.

[0019] Reference Figure 1 and Figure 2 An embodiment of the present application discloses a fluid control component having the functions of forward conduction and reverse cutoff, which is applied to an automotive thermal management system and can realize the flow direction control function of the fluid medium of the thermal management system in conjunction with other components. The specific introduction is as follows.

[0020] Reference Figure 1 and Figure 2The embodiment of the present application discloses a fluid control component, including a first housing 1, a valve core component 5, and a second housing 2. The second housing 2 has a housing chamber 20. The valve core component 5 is at least partially located in the housing chamber 20. The second housing 2 includes a first sub-shell 21 and a second sub-shell 22. The first sub-shell 21 and the second sub-shell 22 are fixedly connected or have an integral structure. For ease of processing, they are preferably fixedly connected. Specifically, the first sub-shell 21 and the second sub-shell 22 are welded and fixed. The wall forming the housing chamber 20 includes the first sub-shell 21 and the second sub-shell 22. In this embodiment, the first sub-shell 21 and the second sub-shell 22 are plates. There is a flow channel between the first sub-shell 21 and the second sub-shell 22 to accommodate The cavity 20 is a part of the flow channel, and the first shell 1 is fixedly connected or limit-connected with the first sub-shell 21; specifically, the first shell 1 and the first sub-shell 21 are connected by welding, threaded connection, screw connection, spring clamping or other fixed connection methods, and the second sub-shell 22 includes a valve mouth part 4, and the valve mouth part 4 has a valve mouth 40. In the valve closing state, the valve core component 5 abuts against the valve mouth part 4 to close the valve mouth 40. Specifically, in the valve opening state, the valve mouth 40 connects the accommodating cavity 20 and the lower space of the valve mouth part 4, and the fluid in the lower space of the valve mouth part 4 enters the accommodating cavity 20 through the valve mouth 40. In the valve closing state, the valve mouth 40 is closed by the valve core component 5, and the fluid in the accommodating cavity 20 cannot pass through the valve mouth 40. Compared with the traditional fluid control component, the fluid control component of this embodiment has a simplified valve body structure. The valve mouth part 4 traditionally located in the valve body is arranged in the second shell body 2. The valve mouth part 4 is an integral structure with the second sub-shell 22. The valve mouth part 4 is molded together during the molding process of the second sub-shell 22. In addition, in the traditional solution, the valve mouth part 4 is located in the valve body, and an internal leakage seal is required between the valve body and the shell. In this embodiment, there is no need to set an additional sealing structure, thereby simplifying the structure of the fluid control component.

[0021] refer to Figure 7 For the implementation method of integrally forming the first sub-shell 21 and the second sub-shell 22, the first sub-shell 21 and the second sub-shell 22 are integrally injection molded, and an insertion port for the valve core component 5 is reserved, the valve core component 5 is inserted into the accommodating cavity of the second shell 2, the first shell 1 and the second shell 2 are fixedly connected, and then the second shell 2 is connected to other parts at the connecting surface 101. The connecting surface 101 can be welded with other components, or it can be a limited connection such as a screw connection.

[0022] refer to Figure 1-Figure 5The fluid control component includes a third shell 3, which is at least partially located in the accommodating chamber 20. The third shell 3 is connected to the first shell 1 or the second shell 2. Specifically, in some embodiments, the third shell 3 is fixedly connected, limitedly connected or integrally formed with the first shell 1. In other embodiments, the third shell 3 is fixedly connected, limitedly connected or integrally formed with the first sub-shell 21, or the third shell 3 is fixedly connected, limitedly connected or integrally formed with the second sub-shell 22. Considering the processing cost, it is preferred that the third shell 3 is an integrally formed structure with the first sub-shell 21 or the second sub-shell 22. The third shell 3 includes a guide portion 31, and the valve core component 5 is slidably matched with the guide portion 31. The valve core component 5 approaches or moves away from the valve port 40 along the guide portion 31. The provision of the guide portion 31 is beneficial to improving the stability of the valve core component 5.

[0023] The fluid control assembly of this embodiment is an L-type one-way valve assembly. In this embodiment, the third housing 3 has a valve cavity 30, the valve core component 5 is at least partially located in the valve cavity 30, the third housing 3 has an outlet 32, the outlet 32 ​​is at least partially located in the side of the third housing 3, the outlet 32 ​​is connected to the valve cavity 30, and the outlet 32 ​​is connected to the accommodating cavity 20. In this embodiment, the fluid can push the valve core component 5 abutting against the valve port 4 from the bottom of the valve core, and the fluid enters the valve cavity 30 through the valve port 40, and then enters the accommodating cavity 20 and other flow channels between the first sub-shell 21 and the second sub-shell 22 through the outlet 32 ​​on the side of the valve cavity 30. The flow path of the fluid is roughly L-shaped. Of course, it is not limited to the L-type. For example, the paving area of ​​the third housing 3 can be appropriately increased, and the outlet 32 ​​can be set at the bottom or top of the third housing 3, so that the fluid enters the valve cavity 30 and reaches other areas from the top or bottom.

[0024] refer to Figure 1 In order to further simplify the structure of the fluid control assembly, in the present embodiment, one end of the third shell 3 is fixedly connected or limitedly connected to the first shell 1. Specifically, the third shell 3 is fixedly connected to the first shell 1 by welding, threaded connection, screw connection, screw connection, screw-on connection or limited-position connection, and the other end of the third shell 3 abuts against the second shell 2. The purpose of the abutment here is to increase the stability of the third shell 3, so that the guide portion 31 located in the third shell 3 is more stable, which is conducive to improving the stability of the movement of the valve core component 5. Of course, in some cases, when the stroke of the valve core component 5 is short, or when the guide portion 31 has a stable structure, such as when the guide portion 31 is a hollow cylinder, the other end of the third shell 3 may not need to abut against the second shell 2; refer to Figure 3 In another embodiment, in order to further simplify, the third shell 3 is an integral structure with the first shell 1, and the end of the third shell 3 away from the first shell 1 abuts against the second shell 2. Of course, as in the above situation, the third shell 3 may not abut against the second shell 2.

[0025] refer to Figure 4 and Figure 5 , also in order to further simplify the structure of the fluid control component, in other embodiments, one of the first sub-shell 21 and the second sub-shell 22 is integrally structured with the third shell 3, and the other of the first sub-shell 21 and the second sub-shell 22 abuts against the third shell 3. Specifically, the first sub-shell 21 and the third shell 3 are integrally structured, and the second sub-shell 22 abuts against the third shell 3, or the second sub-shell 22 and the third shell 3 are integrally structured, and the first sub-shell 21 abuts against the third shell 3. The purpose of the abutment here is to increase the stability of the third shell 3, so that the guide portion 31 located in the third shell 3 is more stable, which is conducive to improving the stability of the movement of the valve core component 5. Of course, in some cases, when the stroke of the valve core component 5 is short, or when the guide portion 31 is stable in structure, such as when the guide portion 31 is a hollow cylinder, the third shell 3 may not need to abut against the second shell 2.

[0026] It should be noted that the third housing 3 is not limited to a shell-shaped component, but also includes components of other shapes, such as a plurality of columnar components, and the guide portion 31 is located on the peripheral wall of the columnar component.

[0027] refer to Figure 6 In order to further simplify the structure of the fluid control component, in another embodiment, the fluid control component includes a guide portion 31, and the guide portion 31 is located in the second shell 2. The valve core component 5 slides with the guide portion 31 located in the second shell 2, that is, the third shell 3 can be completely removed, and the guide portion 31 is set in the second shell 2. The guide portion 31 can be additionally set on the second shell 2, or the second shell 2 can be partially designed as an arc shell, and the outer peripheral wall of the valve core component 5 cooperates with the arc shell to achieve a guiding function. In this embodiment, if the first sub-shell 21 and the second sub-shell 22 are adopted as a split structure, it is preferred to move the joint surface 211 of the first shell 21 and the second shell 22 toward or away from the valve mouth 4, so that the joint surface 211 is away from the guide portion, that is, the valve core component 5 does not pass through the joint surface 211 during its stroke, which can prevent the step or welding overflow at the joint surface 211 from affecting the stability of the valve core component 5.

[0028] In the above embodiment, in order to improve the movement stability of the valve core component 5, reference Figure 8 The guide portion 31 is preferably designed to be a plurality of guide grooves 310, the walls of the guide grooves 310 extend along the axial direction of the valve core component 5, the guide grooves 310 are arranged at intervals along the circumference of the valve core component 5, the valve core component 5 has guide wings 55 corresponding to the guide grooves 310, and the guide wings 55 are slidably matched with the guide grooves 310. Of course, guide grooves 310 can also be provided on the outer periphery of the valve core component 5, and guide ribs can be provided on the third shell 3 or the second shell 2, and the guide grooves 310 are slidably matched with the guide ribs.

[0029] refer to Figure 6In this embodiment, on the one hand, the structure of the valve mouth portion 4 is simplified, and on the other hand, the one-way flow function of the fluid is realized. The wall designed to form the valve mouth 40 includes a first wall surface 41. The first wall surface 41 is located at the second sub-shell 22. The first wall surface 41 expands along the axial direction of the valve core component 5. The diameter of the end close to the first sub-shell 21 is larger than the diameter of the end away from the first sub-shell 21, that is, the first wall surface 41 is roughly in the shape of a bell mouth. The valve mouth portion 4 is designed in this shape, and the difficulty of processing and molding is lower.

[0030] refer to Figure 8 In this embodiment, the valve core component 5 includes a valve core 51 and a sealing member 54. The sealing member 54 is located at the outer periphery of the valve core 51. In the valve closing state, the sealing member 54 abuts against the first wall surface 41 to close the valve port 40. Specifically, the fluid control component of this embodiment includes an elastic member 56. The valve core component 5 includes a valve core 51, a valve stem 52, and a sealing member 54. The valve core 51 and the valve port 4 can move relative to each other. The valve core 51 can open or close the valve port 40 in one direction to achieve the functions of one-way conduction and reverse cutoff. The valve core 51 and the valve stem 52 are fixedly connected or have an integrated structure. The first housing 1 has a guide hole 10 opening toward the valve core component 5.
