[0027] The features and exemplary embodiments of various aspects of the present application will be described below. To make the purpose, technical solutions and advantages of the present application clearer, the present application 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.
[0028] An embodiment of the present application provides a control valve that can be used in a vehicle thermal management system, specifically in a coolant circulation system, and can perform flow isolation, conduction, and switching functions for the thermal management system.
[0029] like Figures 1 to 7 As shown, the control valve 1 implemented in the present application includes a valve body 10 , a valve core 20 and a sealing assembly 30 . The valve body 10 has a valve cavity 101 and a communication port 14. The valve body 10 includes a side wall portion 11, a valve cover 13 and a bottom wall portion 12. Along the axial direction of the side wall portion 11, at least a portion of the side wall portion 11 is located between the bottom wall portion 12 and the valve cover 13. The side wall portion 11, the valve cover 13 and the bottom wall portion 12 define at least a portion of the valve cavity 101. At least a portion of the communication ports 14 are located on the inner surface of the side wall portion 11. The valve cover 13 and the bottom wall portion 12 are both sealed to the side wall portion 11. For example, one of the valve cover 13 and the bottom wall portion 12 is injection molded as an integral structure with the side wall portion 11, and the other is welded to the side wall portion 11 to achieve sealing. The valve cover 13, the bottom wall portion 12 and the side wall portion 11 can jointly define the valve cavity 101. At least a portion of the valve core 20 is located in the valve cavity 101 and the valve core 20 can rotate in the valve cavity 101. In the embodiment of the present invention, the bottom wall portion 12 and the side wall portion 11 are injection molded into an integral structure, and the valve cover 13 and the side wall portion 11 are limitedly arranged and welded and sealed.
[0030] In the radial direction of the side wall portion 11, at least part of the sealing assembly 30 is located between the side wall portion 11 and the valve core 20, and is used to seal the control valve 1. The sealing assembly 30 has a channel 31 that is opposite to and connected to the communication port 14, and is connected to the corresponding communication port 14. In this embodiment, all the communication ports 14 are located in the side wall portion 11. In some other embodiments, a part of the communication ports 14 may be located in the side wall portion 11, and another part of the communication ports 14 may be located in the valve cover 13 and / or the bottom wall portion 12.
[0031] To realize the rotation of the valve core 20, optionally, as Figures 1 to 4 As shown, the control valve 1 may further include a drive assembly 40, which includes a drive member. The drive member may include a motor or a combination of a motor and a transmission gear set. The drive member is in transmission connection with the valve core 20 so that the drive member drives the valve core 20 to rotate. The rotation of the valve core 20 enables different flow paths to be connected, thereby achieving control of the fluid flow path by the control valve 1.
[0032] In some embodiments, the control valve 1 further has a port 102. The port 102 is exposed on the surface of the control valve 1, and fluid can enter or leave the control valve 1 through the port 102. The control valve 1 may further include a connecting pipe. The connecting pipe has a flow channel. One end of the flow channel communicates with the corresponding communication port 14, and the other end forms the port 102 of the control valve 1 or the other end communicates with the port 102. The connecting pipe is hermetically connected to the valve body 10 and is located on the outer peripheral side of the side wall portion 11. The connecting pipe can be connected to other fluid components in the thermal management system. Exemplarily, the fluid components can be structures such as heat exchangers and water pumps.
[0033] Or as Figures 1 to 6 shown, the valve body 10 further includes a flow channel portion 15. The flow channel portion 15 is located outside the side wall portion 11 and is hermetically arranged with the side wall portion 11. For example, the flow channel portion 15 can be integrally injection-molded with the side wall portion 11 and / or the bottom wall portion 12. Optionally, the port 102 corresponds to and communicates with the communication port 14. The port 102 is located on the outer surface of the flow channel portion 15 and at least some of the ports 102 have the same orientation. The flow channel portion 15 has a mounting surface, and the mounting surface can be connected to other fluid components in the thermal management system. Exemplarily, the fluid components can be structures such as heat exchangers and water pumps. Or, in some other embodiments, the port 102 is located on the outer end face side of the side wall portion 11. The control valve can be installed as a module in the integration cavity of the integrated component, and the port 102 can correspond to and communicate with the flow channel in the housing of the integrated component.
[0034] In the embodiments of the present invention, the communication port 14 includes a first port P1, a second port P2, a third port P3, a fourth port P4, a fifth port P5, and a sixth port P6. The first port P1 and the fourth port P4 are adjacent to each other. The second port P2, the third port P3, the fifth port P5, and the sixth port P6 are all located on the outer periphery of the first port P1 and the fourth port P4. Optionally, the fifth port P5, the first port P1, and the third port P3 are arranged along the circumferential direction of the valve body 10, and the sixth port P6, the fourth port P4, and the second port P2 are arranged along the circumferential direction of the valve body 10. The fifth port P5 and the sixth port P6, the fourth port P4 and the first port P1, and the second port P2 and the third port P3 are all arranged along the axial direction of the valve body 10. At this time, the first port P1 and the sixth port P6 are misaligned both in the circumferential direction and the axial direction of the valve body 10, that is, the first port P1 and the sixth port P6 are arranged diagonally at this time. Similarly, the fourth port P4 and the third port P3 are arranged diagonally. At this time, the valve core 20 can connect the first port P1 to any one of the second port P2, the third port P3, the fifth port P5, and the sixth port P6, and the valve core 20 can connect the fourth port P4 to any one of the second port P2, the third port P3, the fifth port P5, and the sixth port P6. Through the above arrangement, a plurality of communication ports 14 that can communicate with both the first port P1 and the fourth port P4 are all located around the first port P1 and the fourth port P4, which facilitates implementing the above communication relationship through a relatively simple valve core 20.
[0035] Accordingly, the port 102 of the control valve 1 includes a first port M1, a second port M2, a third port M3, a fourth port M4, a fifth port M5, and a sixth port M6. At least a partial number of ports 102 can face the same direction and are located in the flow channel portion 15. The first port P1 communicates with the first port M1, the second port P2 communicates with the second port M2, the third port P3 communicates with the third port M3, the fourth port P4 communicates with the fourth port M4, the fifth port P5 communicates with the fifth port M5, and the sixth port P6 communicates with the sixth port M6.
[0036] In some embodiments, the valve core 20 has a first outer cavity 21 and an inner cavity 23. The inner cavity 23 is closer to the axis of the valve core 20 than the first outer cavity 21. The inner cavity 23 connects at least two first outer cavities 21. The first outer cavities 21 connected through the inner cavity 23 are arranged in a staggered manner both in the circumferential direction and the axial direction of the valve body 10. Through the above arrangement, it is convenient to realize the connection of at least two communication ports 14 arranged diagonally.
[0037] Furthermore, when the first port P1 is connected to the communication port 14 arranged diagonally to the first port P1, and the fourth port P4 is connected to the communication port arranged diagonally to the fourth port P4, for example, when the first port P1 is connected to the sixth port P6 and the fourth port P4 is connected to the third port P3, in order to enable the conduction cavity of the valve core 20 to achieve the above connection relationship, combined with Figure 5 and Figure 6 as shown, the inner cavity 23 of the valve core 20 includes a first inner cavity 231 and a second inner cavity 232 which are arranged separately from each other. The second inner cavity 232 is closer to the axis of the valve core 20 than the first inner cavity 231. In the same control working mode, the first inner cavity 231 can be connected to one of the first port P1 and the fourth port P4, and the second inner cavity 232 can be connected to the other of the first port P1 and the fourth port P4.
[0038] Furthermore, in order to connect at least two communication ports 14 arranged in the circumferential direction of the valve body 10, in some embodiments, the valve core 20 further has a second outer cavity 22. The first outer cavity 21 and the second outer cavity 22 are arranged separately from each other. The second outer cavity 22 can connect at least two communication ports 14 adjacent to each other in the circumferential direction of the valve body 10. In this article, the separate arrangement of two cavities means that there is no connection between the two cavities in the control valve 1, and the fluid does not interact between the two cavities. Along the circumferential direction of the valve core 20, the angle of the second outer cavity 22 facing the conduction port of the valve body 10 is greater than the angle of the first outer cavity 21 facing the conduction port of the valve body 10.
[0039] Furthermore, in order to enable the valve core 20 to connect the first port P1 to any one of the second port P2, the third port P3, the fifth port P5, and the sixth port P6, and enable the valve core 20 to connect the fourth port P4 to any one of the second port P2, the third port P3, the fifth port P5, and the sixth port P6, combined withFigures 5 to 18 As shown, in some embodiments, the first outer cavity 21 of the valve core 20 includes a first cavity 201, a second cavity 202, a third cavity 203, a fourth cavity 204, a fifth cavity 205, a sixth cavity 206, a seventh cavity 207, and an eighth cavity 208. The second outer cavity 22 includes a ninth cavity 209, a tenth cavity 2010, and an eleventh cavity 2011. The valve core 20 further has a first isolation cavity 241 and a second isolation cavity 242, and both the first isolation cavity 241 and the second isolation cavity 242 can close the communication port 14.
[0040] Among them, the third cavity 203, the first cavity 201, the first isolation cavity 241, the second isolation cavity 242, the seventh cavity 207, the fifth cavity 205, and the ninth cavity 209 are arranged along the circumferential direction of the valve core 20. The fourth cavity 204, the second cavity 202, the eighth cavity 208, the sixth cavity 206, the tenth cavity 2010, and the eleventh cavity 2011 are arranged in an array along the circumferential direction of the valve core 20. The first cavity 201 and the fourth cavity 204 are arranged axially along the valve core 20. The second cavity 202 and the first isolation cavity 241 are arranged axially along the valve core 20. The second isolation cavity 242 and the eighth cavity 208 are arranged axially along the valve core 20. The sixth cavity 206 and the seventh cavity 207 are arranged axially along the valve core 20. Among them, the angles of any one of the first cavity 201, the second cavity 202, the third cavity 203, the fourth cavity 204, the fifth cavity 205, the sixth cavity 206, the seventh cavity 207, and the eighth cavity 208 facing the conduction port of the valve body 10 can be equal, and can be arranged opposite to and communicate with a communication port 14. The angles of any one of the ninth cavity 209, the tenth cavity 2010, and the eleventh cavity 2011 facing the conduction port of the valve body 10 can be equal, and can be arranged opposite to and communicate with at least two communication ports 14. In this article, the closing of a certain communication port 14 means that in the control valve 1, this communication port 14 is not communicated with other communication ports. The axial direction of the valve core 20 is parallel or coincident with the axial direction of the valve body 10, and the circumferential direction of the valve core 20 is coaxial or coincident with the circumferential direction of the valve body 10.
[0041] Furthermore, in some embodiments, the first inner cavity 231 includes a twelfth cavity 2012 and a thirteenth cavity 2013, the second inner cavity 232 includes a fourteenth cavity 2014 and a fifteenth cavity 2015. The twelfth cavity 2012 communicates the first cavity 201 and the second cavity 202. The thirteenth cavity 2013 communicates the seventh cavity 207 and the eighth cavity 208. The fourteenth cavity 2014 communicates the third cavity 203 and the fourth cavity 204. The fifteenth cavity 2015 communicates the fifth cavity 205 and the sixth cavity 206. The part of the fourteenth cavity 2014 is closer to the axis of the valve core 20 than the part of the twelfth cavity 2012. The part of the fifteenth cavity 2015 is closer to the axis of the valve core 20 than the part of the thirteenth cavity 2013.
[0042] Please further combine Figure 9 andFigure 10 As shown in the figure, the valve core 20 includes a top plate 251, a bottom plate 252, a transmission shaft 254, and a partition plate 253. The top plate 251 and the bottom plate 252 are arranged along the axial direction of the valve core 20. The partition plate 253 is located between the top plate 251 and the bottom plate 252. The partition plate 253 includes a vertical partition plate extending along the axial direction of the valve core 20 and a horizontal partition plate extending in a direction perpendicular to the axial direction. The vertical partition plate and the horizontal partition plate can define at least part of the wall of the conduction cavity and / or the isolation cavity. At least part of the transmission shaft 254 is located on the side of the top plate 251 facing away from the bottom plate 252. The transmission shaft 254 can be integrally injection-molded with the top plate 251, the bottom plate 252, and the partition plate 253. The drive assembly 40 is in transmission connection with the transmission shaft 254.
[0043] To facilitate the fabrication of the above-mentioned first inner cavity 231 and second inner cavity 232, the twelfth cavity 2012, the thirteenth cavity 2013, and the fourteenth cavity 2014 penetrate through the top plate 251, and the fifteenth cavity 2015 penetrates through the bottom plate 252. Through the above arrangement, on the one hand, it is convenient to fabricate the above-mentioned inner cavities. On the other hand, compared with the case where the above four inner cavities 26 all penetrate through the bottom plate 252 or the top plate 251, the control valve 1 provided by the embodiment of the present invention facilitates the top plate 251 and the bottom plate 252 of the valve core 20 to have better strength.
[0044] Further, the transmission shaft 254 passes through 13 and is in transmission connection with the driving member in the drive assembly 40. To reduce fluid leakage, in some embodiments, the control valve 1 further includes a sealing ring 103, and the sealing ring 103 is clamped between the valve core 20 and the valve cover 13. When the fourteenth cavity 2014 penetrates through the top plate 251, the fourteenth cavity 2014 is relatively close to the axis of the valve core 20 at this time. The fluid flowing through the fourteenth cavity 2014 is likely to impact the sealing ring, easily causing damage or displacement of the sealing ring and affecting the sealing performance. To solve the above problems, in some embodiments, the valve core 20 in the embodiment of the present invention further includes a first baffle 255. The first baffle 255 can be welded and sealed with the top plate 251, so that the first baffle 255 closes the fourteenth cavity 2014, and the fourteenth cavity 2014 is fluid-isolated from the valve cavity 101. The first baffle 255 and the transmission shaft 254 can be welded and sealed.
[0045] Further, to prevent fluid cross-flow between the twelfth cavity 2012, the thirteenth cavity 2013, and the fourteenth cavity 2014, in some embodiments, the control valve 1 further includes a second baffle 256. The second baffle 256 can be welded and sealed with the top plate 251, so that the second baffle 256 closes the twelfth cavity 2012 and the thirteenth cavity 2013, and both the twelfth cavity 2012 and the thirteenth cavity 2013 are fluid-isolated from the valve cavity 101. In specific implementation, the top plate 251 is provided with a groove structure, and the first baffle 255 and the second baffle 256 can be arranged in the corresponding groove structures.

[0054] The control valve 1 further includes a sealing assembly 30. Along the radial direction of the valve core 20, the sealing assembly 30 is located between the valve core 20 and the valve body 10. The sealing assembly 30 has a pore 31, and the pore 31 is correspondingly connected to the communication port 14. In some working modes of the control valve 1, some communication ports 14 are closed through the first outer cavity 21 and / or the second outer cavity 22. To reduce the leakage of the control valve 1 and improve the sealing performance of the control valve 1, in some embodiments, combined with Figures 5 to 7As shown, along the circumferential direction of the sealing component 30, on the side of the second port P2 away from the fourth port P4, the central angle corresponding to the sealing component 30 is greater than the central angle corresponding to the second port P2; on the side of the third port P3 away from the first port P1, the central angle corresponding to the sealing component 30 is greater than the central angle corresponding to the third port P3; on the side of the fifth port P5 away from the first port P1, the central angle corresponding to the sealing component 30 is greater than the central angle corresponding to the fifth port P5; on the side of the sixth port P6 away from the fourth port P4, the central angle corresponding to the sealing component 30 is greater than the central angle corresponding to the sixth port P6.
[0055] In specific implementation, in combination with Figures 5 to 7 As shown, the sealing component 30 includes a transverse rib 32 and a longitudinal rib 33. The transverse rib 32 extends along the circumferential direction of the sealing component 30, and the longitudinal rib 33 extends along the axial direction of the sealing component 30. The transverse rib 32 intersects with the longitudinal rib 33, and the duct 31 is correspondingly located in the area defined by the intersection of the transverse rib 32 and the longitudinal rib 33. The sealing component 30 has six ducts, the same number as the number of the communication ports 14. These six ducts 31 are arranged in three columns along the circumferential direction of the sealing component 30 and in two rows along the axial direction of the sealing component. Correspondingly, the area defined by the intersection of the transverse rib 32 and the longitudinal rib 33 has six first areas corresponding to the ducts 31. The six first areas are arranged in two rows and three columns, and each first area is provided with a duct 31.
[0056] In addition, to enable the first outer cavity 21 and / or the second outer cavity 22 to close the corresponding communication ports 14, the area defined by the intersection of the transverse rib 32 and the longitudinal rib 33 further has four second areas. These second areas are arranged in two columns. Along the circumferential direction of the sealing component 30, the three columns of first areas are integrally located between the two columns of second areas. It can be understood that the conduction port of the second outer cavity 22 facing the valve body 10 can communicate with two conduction ports. However, when the conduction port of the second outer cavity 22 communicates with three conduction ports, to achieve the function of the second outer cavity 22 closing the communication port 14, the number of the second areas of the sealing component 30 needs to be increased adaptively. The corresponding relationship between the first outer cavity 21 and the second areas is similar to the corresponding relationship between the second outer cavity and the second areas.
[0057] Furthermore, to accurately position the sealing component 30 in the valve body 10 and prevent the position of the sealing component 30 from shifting, in some embodiments, as Figure 7 and Figure 8 shown, the valve body 10 includes a plurality of limiting portions 121 arranged at intervals along the circumferential direction of the valve body 10. The limiting portions 121 protrude from the bottom wall portion 12 of the valve body 10. The sealing component 30 includes a plurality of concave portions 34 arranged at intervals along the circumferential direction of the sealing component 30. The limiting portions 121 are inserted into the grooves of the corresponding concave portions 34, and the limiting portions 121 are limitedly arranged with the wall surfaces of the grooves.
[0058] To improve the accuracy of the position of the sealing component 30 and the accuracy of the installation of the sealing component 30, in some embodiments, such as Figure 7 As shown, the sealing component 30 includes a first rib portion 331. Along the axial direction of the sealing component 30, the first rib portion 331 is located at one end of the sealing component 30, and the extension distance of the first rib portion 331 along the axial direction of the sealing component 30 is less than the axial length of the sealing component 30.
[0059] In summary, according to the control valve 1 provided by the embodiments of the present application, since the valve core 20 can communicate any one of the first port P1 with the second port P2, the third port P3, the fifth port P5, and the sixth port P6, and the valve core 20 can communicate the fourth port P4 with any one of the second port P2, the third port P3, the fifth port P5, and the sixth port P6. To achieve the above communication relationship, the fifth port P5, the first port P1, and the third port P3 are arranged in the circumferential direction of the valve body 10, the sixth port P6, the fourth port P4, and the second port P2 are arranged in the circumferential direction of the valve body 10, and the fifth port P5 and the sixth port P6, the fourth port P4 and the first port P1, and the second port P2 and the third port P3 are all arranged in the axial direction of the valve body 10, so that a plurality of communication ports 14 that can communicate with both the first port P1 and the fourth port P4 are all located around the first port P1 and the fourth port P4, which facilitates the realization of the above communication relationship through a relatively simple valve core 20.
