Technical Field

[0001] This invention relates to the field of fluid control technology, and more particularly to a valve device and integrated component for a vehicle thermal management system. Background Technology

[0002] Valve devices are used to distribute coolant in vehicles. As the number of heat sources in vehicles increases, the number of fluid distribution paths regulated by valve devices also increases accordingly. It can be understood that the number of modes corresponding to the number of fluid distribution paths regulated by valve devices will also increase accordingly. Currently, valve devices usually have two valve core structures to adjust the mode corresponding to the number of fluid distribution paths in the vehicle. When one valve core switches modes, the current mode corresponding to the other valve core will be affected. Summary of the Invention

[0003] The purpose of this invention is to provide a valve device and integrated assembly in which, when a valve core switching mode is in one valve core switching mode, the current mode corresponding to the second valve core is not affected by the first valve core switching mode.

The first engaging tooth portion includes an actuating tooth portion and a plurality of first teeth portions. The second engaging tooth portion includes a plurality of second teeth portions and at least one disengaging tooth portion. When the first teeth portion rotates to the disengaging tooth portion position, the second valve core disengages from the first valve core. When the actuating tooth portion engages with the second engaging tooth portion, the first valve core can drive the second valve core to engage and rotate.

[0005] In this application's technical solution, the first valve core includes a first flow cavity, and the second valve core includes a second flow cavity. The first flow cavity connects to one of two inlets and one of two outlets, and the second flow cavity connects to the other of the two inlets and the other of the two outlets. The first valve core includes a first engaging tooth portion, and the second valve core includes a second engaging tooth portion. The first engaging tooth portion includes an actuating tooth portion and multiple first teeth portions, and the second engaging tooth portion includes multiple second teeth portions and at least one disengaging tooth portion. When the first teeth portion rotates to the disengaging tooth portion position, the second valve core disengages from the first valve core. When the actuating tooth portion engages with the second engaging tooth portion, the first valve core can drive the second valve core to engage and rotate. In this way, when the second valve core rotates to the desired operating mode, the second valve core disengages from the first valve core, and the first valve core can rotate independently as needed, switching the operating mode corresponding to the first valve core. Thus, the current mode corresponding to the second valve core is not affected by the switching mode of the first valve core.

[0007] In this application's technical solution, the first valve core includes a first engaging tooth portion, and the second valve core includes a second engaging tooth portion. The first engaging tooth portion includes an actuating tooth portion and multiple first teeth portions, and the second engaging tooth portion includes multiple second teeth portions and at least one disengaging tooth portion. When the first teeth portion rotates to the disengaging tooth portion position, the second valve core disengages from the first valve core. When the actuating tooth portion engages with the second engaging tooth portion, the first valve core can drive the second valve core to engage and rotate. In this way, when the second valve core rotates to the desired operating mode, the second valve core disengages from the first valve core, and the first valve core can rotate independently as needed, switching the operating mode corresponding to the first valve core. The current mode corresponding to the second valve core is not affected by the switching mode of the first valve core. Attached Figure Description

[0026] The embodiments of this application will be further described below with reference to the accompanying drawings:

[0027] Please see Figures 1 to 10As shown, one embodiment of this application provides an integrated component 1000, which can be used in a vehicle thermal management system. The integrated component 1000 includes a flow channel plate assembly 200, which includes a flow channel portion 2001 and a flow channel cavity 2001a. The integrated component 1000 also includes a fluid management device 2002. The flow channel plate assembly 200 and the fluid management device 2002 are fixedly connected or limitedly connected. The fluid management device 2002 includes at least a valve device 100. In this embodiment, the fluid management device 2002 includes a valve device 100 and an electric pump 300. Specifically, in this embodiment, the fluid management device includes a valve device 100 and two electric pumps 300. The valve device 100 can control or regulate the isolation, conduction, and switching functions of the coolant in the flow channel cavity 2001a. When the fluid management device 2002 includes an electric pump 300, at least one of the inlet and outlet 1164b of the electric pump 300 can be connected to the corresponding flow channel cavity 2001a through the mounting part 2001b, and the electric pump 300 can provide power for the flow of coolant. The flow channel plate assembly 200 includes an interface part 2001c, which is connected to an external pipe. Coolant outside the interface part 2001c can enter the flow channel cavity 2001a through the interface part 2001c, or coolant in the flow channel cavity 2001a can be transported to the outside of the integrated assembly 1000 through the interface part 2001c.

[0028] As one implementation method, please refer to Figures 1 to 10As shown in the figure, a valve device 100 according to an embodiment of the present invention is provided. The valve device 100 includes a valve body 11, a valve core assembly 100a, and a sealing assembly 14. The valve body 11 has a valve cavity 111, an inlet, and an outlet. The valve body 11 includes a side wall portion 113, a top wall portion 114, and a bottom cover portion 115. At least a portion of the side wall portion 113 is located between the bottom cover portion 115 and the top wall portion 114. The side wall portion 113, the top wall portion 114, and the bottom cover portion 115 define at least a portion of the valve cavity 111. The inlet and the outlet are respectively located on the inner surface of the side wall portion 113, and the inner surface of the side wall portion 113 faces the valve cavity 111. The top wall portion 114 and the bottom cover portion 115 are both sealed to the side wall portion 113. At least a portion of the valve core assembly 100a is located in the valve cavity 111, and the valve core assembly 100a can rotate under the drive of an external drive assembly. Along the axial direction of the side valve core assembly 100a, the sealing assembly 14 is located between the side wall portion 113 and the valve core assembly 100a, for sealing the valve device 100. The valve core assembly 100a includes a guiding cavity 100b with a guiding port 110b1. The sealing assembly 14 has a channel opposite to and communicating with the inlet and / or outlet, which also communicates with the guiding port 110b1 to connect the corresponding inlet and / or outlet. It should be noted that the valve device 100 can be mounted as a separate component on the flow channel plate assembly 200, or the valve body 11 can be formed on the flow channel plate assembly 200, with other components of the valve device 100, excluding the valve body 11, mounted on the flow channel plate assembly 200. In this embodiment, the valve body 11 is formed on the flow channel plate assembly 200, and other components, excluding the valve body 11, are mounted on the flow channel plate assembly 200. This approach facilitates the miniaturization of the integrated assembly 1000.

[0029] Optionally, the valve device 100 further includes a drive assembly 15, which includes a drive member capable of driving the valve core assembly 100a via a combination of a motor and a transmission gear set. The drive member is connected to the valve core assembly 100a to rotate, thereby enabling the opening of different inlets and / or outlets. In this embodiment, the valve core assembly 100a includes a first valve core 12 and a second valve core 13, arranged side-by-side. The axis of the first valve core 12 is parallel to the axis of the second valve core 13. The first valve core 12 is connected to the drive member, and the first valve core 12 can drive the second valve core 13.

[0030] In some other embodiments, the valve device 100 further includes a connecting pipe 16 having a flow channel 161, one end of which is connected to a corresponding communication port 112, and the other end forming a port 162 of the valve device 100. The port 162 may be integrated on the same plane or configured according to the needs of the application. Alternatively, the connecting pipe 16 may also be connected to other fluid components in the thermal management system. For example, the fluid components may be structures such as heat exchangers.

[0031] With the increasing number of heat sources in vehicles, the number of fluid flow paths regulated by valve devices also increases accordingly. Currently, valve devices typically employ two valve core structures to adjust the modes corresponding to the number of fluid flow paths in the vehicle. When one valve core switches modes, the current mode corresponding to the other valve core is affected. Therefore, new requirements are being placed on the structural design of valve devices, and this application arose in this context.

[0032] As one implementation method, please refer to Figures 3 to 10 As shown, a valve device 100 includes a valve body 11, a first valve core 12, and a second valve core 13. The valve body 11 includes a valve cavity 116, and the first valve core 12 and the second valve core 13 are located in the valve cavity 116. The valve body 11 includes at least two inlets and at least two outlets. Specifically, the inlets and outlets are arranged on opposite sides along the axial direction of the valve device 100. The first valve core 12 includes a first flow cavity 121, and the second valve core 13 includes a second flow cavity 131. The first flow cavity 121 can connect to one of the two inlets and one of the two outlets, and the second flow cavity 131 can connect to the other of the two inlets. The first valve core 12 includes a first engaging tooth portion 122, and the second valve core 13 includes a second engaging tooth portion 134. The first engaging tooth portion 122 includes an actuating tooth portion 1222 and a plurality of first teeth 1221. The second engaging tooth portion 134 includes a plurality of second teeth 1342 and at least one disengaging tooth portion 1341. When any first tooth portion 1221 rotates to the position of the disengaging tooth portion 1341, the second valve core 13 disengages from the first valve core 12. When the actuating tooth portion 1222 engages with any tooth of the second engaging tooth portion 134, the first valve core 12 can drive the second valve core 13 to engage and rotate. In this way, when the first and second valve cores rotate to the desired operating mode, the second valve core disengages from the first valve core, and the first valve core can rotate independently as needed, switching the operating mode corresponding to the first valve core. Thus, the current mode corresponding to the second valve core is not affected by the switching mode of the first valve core. Secondly, setting the dual valve cores to rotate asynchronously helps reduce the torque output of the drive assembly 15, thereby reducing the cost of the drive assembly 15.

[0033] Specifically, as one implementation method, please refer to Figures 3 to 8As shown, the first valve core 12 includes a first end 123 and a second end 124, and the second valve core 13 includes a third end 135 and a fourth end 136. The first end 123 and the third end 135 are disposed on the same side. The first tooth 1221 extends from the first end 123 to the second end 124. The actuating tooth 1222 extends from the first end 123 to the second end 124. The extension length of the actuating tooth 1222 is greater than the extension length of the first tooth 1221. The second tooth 1342 extends from the third end 135 to the fourth end 136. The disengaging tooth 1341 extends from the fourth end 136 to the third end 135. Along the axial direction of the valve device 100, the end of the disengaging tooth 1341 near the third end 135 is spaced apart from the end of the first tooth 1221 near the second end 124 by a predetermined distance. When the first tooth 1221 of the first valve core 12 rotates to the position where it disengages from the tooth 1341, the second valve core 13 disengages from the first valve core 12. It can be understood that at this time, the second valve core 13 is in a pre-set operating mode. Thus, the first and first valve core 12 housings can rotate independently, switching the mode corresponding to the first valve core 12. It can be understood that the conduction or isolation of the flow channel cavity by the second valve core 13 is not affected by the rotation of the first valve core 12. Secondly, while achieving mode switching, it is beneficial to simplify the structure of the valve core assembly 110a. As a specific implementation, the first end 123 is flush with the second end 124, and the third end 135 is flush with the second end 124. It can be understood that one end of the first meshing tooth 122 is flush with the second tooth 1342, and the other end of the starting tooth 1222 is flush with the second meshing tooth 134. This helps to simplify the sealing structure between the valve core assembly 110a and the corresponding wall of the valve cavity 116, such as the sealing structure between the valve core assembly 110a and the side wall.

[0034] Furthermore, as one implementation method, please refer to Figures 1 to 9 As shown, the first flow cavity 121 includes a first flow port 1211 and a second flow port 1212. The first flow port 1211 is on the same side as the first end 123 and is located near the outer periphery of the first valve core 12 relative to its central axis. The second flow port 1212 is on the same side as the second end 124 and is located near the central axis of the first valve core 12 relative to its outer periphery. Thus, one inlet can be connected to the second flow port 1212, and multiple outlets can be connected to the first flow cavity, such as three outlets. This allows for the sharing of a single wellhead when switching between the three modes of the integrated component 1000, simplifying the structure of the integrated component 1000. In this embodiment, the first flow cavity is a cylindrical hole structure, and the point where the axis of the first flow cavity intersects the second end face is located on the axis of the first valve core 12.

[0035] As one implementation method, please refer to Figures 1 to 9 As shown, the inlet communicating with the first flow cavity is defined as the first inlet 117, and the outlet communicating with the first flow cavity is defined as the first outlet 119. There are three first outlets 119, all of which can communicate with the first flow port 1211. There is one first inlet 117, which is always communicating with the second flow port 1212. By setting the second flow cavity 131 to form a certain angle with the axis of the second valve core 13, it is beneficial to simplify the number of pipes communicating with the third flow port 1311 and / or the fourth flow port 1312, thereby simplifying the structure of the valve device 100.

[0036] As one implementation method, please refer to Figures 1 to 9 As shown, the second flow cavity includes a third flow port 1311 and a fourth flow port 1312. The third flow port 1311 is on the same side as the third end 135 and is located near the outer periphery of the second valve core 13 relative to its central axis. The fourth flow port 1312 is on the same side as the fourth end 136 and is located near the central axis of the second valve core 13 relative to its outer periphery. Three disengagement teeth 1341 are evenly distributed along the circumferential direction of the second valve core 13. Thus, three outlets corresponding to the second valve core 13 housing can be provided, which helps increase the number of flow paths corresponding to the second valve core 13, and consequently, increases the number of operating modes corresponding to the valve device 100.

[0037] To further simplify the structure of the valve device 100, please refer to the following implementation method: Figures 1 to 10 As shown, the inlet communicating with the second flow cavity is defined as the second inlet 118, and the outlet communicating with the second flow cavity is defined as the second outlet 119a. There are three second outlets 119a, all of which can communicate with the third flow port 1311. There is one second inlet 118, which is always connected to the fourth flow port 1312. The second inlet 118 can serve as a common inlet, meaning one inlet can correspond to three outlets, enabling switching between three modes. This simplifies the number of interfaces and further simplifies the structure of the valve device 100. In this embodiment, the second flow cavity has a cylindrical hole structure, and the point where the axis of the second flow cavity intersects the fourth end face is located on the axis of the second valve core 13.

[0038] To further position and support the first valve core 12 and the second valve core 13, the valve body 11 includes a main body portion 119b and a support portion 119c. Both the first valve core 12 and the second valve core 13 are connected to the support portion 119c for limiting. The wall portion corresponding to the valve cavity 116 includes the main body portion 119b, and the support portion 119c is located in the valve cavity 116 and is fixedly connected to the main body portion 119b. This facilitates the limiting of the first valve core 12 and the second valve core 13. For example, the first valve core 12 and the second valve core 13 can have the same positioning reference, which helps to improve the manufacturing and assembly accuracy of the valve device 100.

[0039] The first valve core 12 includes a first positioning portion 125 and a first main portion 126. The second valve core 13 includes a second positioning portion 137 and a second main portion 138. A first meshing tooth portion 122 protrudes from the outer peripheral wall of the first main portion 126. A first end portion 123 is formed at the end of the first main portion 126. The first positioning portion 125 is arranged from the first end portion 123 along the axial direction of the valve device 100. A second meshing tooth portion 134 protrudes from the outer peripheral portion of the second main portion 138. A third end portion 135 is formed at the end of the third main portion. The second positioning portion 137 is arranged from the third end portion 135 along the axial direction of the valve device 100. A support portion 119c supports a first support portion 119C1 and a second support portion 119C2. The first positioning portion 125 is in a limiting fit with the first support portion 119C1, and the second positioning portion 137 is in a limiting fit with the second support portion 119C2. It should be noted that the above-mentioned limiting fit includes clearance fit or transition fit. It can be understood that under the action of the driving member, the first positioning part 125 can rotate around the wall corresponding to the support part 119C1, and the second positioning part 137 can rotate around the wall corresponding to the support part 119C2.

[0040] Please refer to Figures 1 to 10 As shown, the valve device 100 includes a sealing assembly 14, which includes a first sealing gasket 141 and a second sealing gasket 142. The first sealing gasket 141 is disposed between the first positioning part 125, the second positioning part 137 and the corresponding wall portion of the valve cavity 116. The second sealing gasket 142 is disposed between the second end 124, the fourth end 136 and the corresponding wall portion of the valve cavity 116. The first sealing gasket 141 includes a first connecting channel 1411, and the second sealing gasket 142 includes a second connecting channel 1421, a first sub-sealing gasket 1422, and a second sub-sealing gasket 1423. Multiple first connecting channels 1411 are included, and the number of first connecting channels 1411 is consistent with the number of outlets. The first sub-sealing gasket 1422 and the second sub-sealing gasket 1423 both include a second connecting channel 1421.

[0041] Please refer to Figures 1 to 10As shown, this application also discloses an integrated component 1000, which includes a flow channel plate assembly and a valve device 100. The valve device 100 includes a valve body 11, a first valve core 12, and a second valve core 13. The valve body 11 is formed in the flow channel plate assembly and includes a valve cavity 116. The first valve core 12 and the second valve core 13 are located in the valve cavity 116. The valve body 11 includes at least two inlets and at least two outlets, which are arranged on opposite sides along the axial direction of the valve device 100. The first valve core 12 includes a first flow cavity 121, and the second valve core 13 includes a second flow cavity 131. The first flow cavity 121 is capable of connecting one of the two inlets and one of the two outlets. Firstly, the second flow chamber 131 can connect the other of the two inlets and the other of the two outlets. The first valve core 12 includes a first engaging tooth portion 122, and the second valve core 13 includes a second engaging tooth portion 134. The first engaging tooth portion 122 includes an actuating tooth portion 1222 and a plurality of first teeth portions 1221. The second engaging tooth portion 134 includes a plurality of second teeth portions 1342 and at least one disengaging tooth portion 1341. When the first tooth portion 1221 rotates to the position of the disengaging tooth portion 1341, the second valve core 13 disengages from the first valve core 12. When the actuating tooth portion 1222 engages with the second engaging tooth portion 134, the first valve core 12 can drive the second valve core 13 to engage and rotate. In this way, when the second valve core rotates to the desired working mode, the second valve core disengages from the first valve core, and the first valve core can rotate independently as needed, switching the working mode corresponding to the first valve core. Thus, the current mode corresponding to the second valve core is not affected by the switching mode of the first valve core.
