Description

Technical Field

[0001] This invention relates to the field of automotive technology, specifically to a multi-way water valve and a vehicle. Background Technology

[0002] Currently, the electronic water valves used in new energy vehicles are mostly three-way valves and four-way valves (both ball valves). Multiple three-way and four-way valves are needed to switch between and connect multiple water circuits (battery, motor, heater) in series or parallel, resulting in complex piping and high costs.

[0003] Therefore, multi-way water valves (pivot valve type) have emerged, which can realize the rotation of the water valve in a valve chamber, and at least two external flow channels can be connected to one of the valve core flow channels to realize the switching of multiple different circuit water channels.

[0004] However, if the multi-port water valve corresponds to two different expansion tanks with a large temperature difference, the multi-port water valve is prone to cross-contamination when switching states. This can cause coolant to flow from one tank to the other, resulting in reduced coolant levels, which affects cooling performance and increases heat loss. Summary of the Invention

[0005] In view of the defects existing in the prior art, the purpose of the present invention is to provide a multi-way water valve and vehicle, which can solve the problem that the multi-way water valve used in the prior art is prone to crosstalk during state switching, causing coolant to flow from one reservoir to another, resulting in reduced coolant, affecting cooling performance and increasing heat loss.

[0006] To achieve the above objectives, the technical solution adopted by the present invention is as follows:

[0007] On one hand, the present invention provides a multi-way water valve, comprising:

[0008] The outer cylinder has a first water passage group and a second water passage group connected at intervals on its axial side wall. Both the first water passage group and the second water passage group include at least three water passage pipes spaced apart in the circumferential direction of the outer cylinder.

[0009] A valve core is rotatably disposed within the outer cylinder. The valve core has a first connecting groove corresponding to the position of the first water passage group and a second connecting groove corresponding to the position of the second water passage group. The first connecting groove can connect at least two adjacent water passage pipes in the first water passage group, and the second connecting groove can connect at least two adjacent water passage pipes in the second water passage group. When the valve core rotates relative to the outer cylinder, the first connecting groove and / or the second connecting groove can be switched to connect to different adjacent water passage pipes in their corresponding water passage group.

[0010] In some alternative embodiments, the valve core includes an inner cylinder and support frames disposed at both ends of the inner cylinder, the first connecting groove and the second connecting groove are disposed on the side wall of the inner cylinder, and the first connecting groove and the second connecting groove are spaced apart in the axial direction of the inner cylinder.

[0011] In some alternative solutions, a sealing sleeve is provided between the inner cylinder and the outer cylinder. The sealing sleeve is rotatable relative to the inner cylinder and fixed in position relative to the outer cylinder. The sealing sleeve is provided with a water passage hole corresponding to the water passage pipe.

[0012] In some alternative designs, the cross-section of the water passage is rectangular.

[0013] In some alternative embodiments, a sealing ring is provided between the first and second connecting grooves in the axial direction of the inner cylinder, the sealing ring being located between the inner cylinder and the sealing sleeve.

[0014] In some alternative solutions, the inner sidewall of the sealing sleeve is provided with multiple axial sealing strips at intervals, which abut against the outer sidewall of the inner cylinder.

[0015] In some alternative configurations, the first and second water passage groups are symmetrically arranged along the radial plane of the outer cylinder.

[0016] In some alternative solutions, both the first and second water passage groups include three water passage pipes.

[0017] In some alternative solutions, the length of the first connecting groove in the circumferential direction is less than the length of the second connecting groove in the circumferential direction.

[0018] On the other hand, the present invention provides a vehicle including any of the multi-way water valves described above.

[0019] Compared with the prior art, the advantages of the present invention are as follows: a first water passage group and a second water passage group are connected at intervals on the side wall of the outer cylinder in the axial direction. The valve core is rotatably disposed in the outer cylinder. The valve core is provided with a first connecting groove corresponding to the position of the first water passage group and a second connecting groove corresponding to the position of the second water passage group. The first connecting groove can connect at least two adjacent water passage pipes in the first water passage group, and the second connecting groove can connect at least two adjacent water passage pipes in the second water passage group. This arrangement forms a multi-way valve with two layers of at least three-way valves combined together, and when the valve core rotates relative to the outer cylinder, it can simultaneously drive the two layers of at least three-way valves, so that the first connecting groove and / or the second connecting groove can be switched to connect to different adjacent water passage pipes in their corresponding water passage group. When the valve core rotates relative to the outer cylinder, the first connecting slot can switch to connect with different adjacent water pipes in its corresponding water passage group, or the second connecting slot can switch to connect with different adjacent water pipes in its corresponding water passage group, or both the adjacent water pipes connected to the first and second connecting slots can change. A servo motor connected to the valve core determines the valve core's rotation, thus enabling the entire valve core to rotate relative to the outer cylinder, thereby switching the connection between the first and / or second connecting slots and different adjacent water pipes in their corresponding water passage groups. This single-valve-body layered multi-way water valve achieves a "one valve body, two valves" structure, solving the cross-contamination problem of existing single-layer multi-way valves when connecting two different water tanks, and reducing the need for a drive unit, thus minimizing the space occupied by other vehicle components.

[0027] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0029] like Figure 1 , Figure 2 and Figure 3 As shown, in one aspect, the present invention provides a multi-way water valve, comprising: an outer cylinder 1 and a valve core 2. A first water passage group 11 and a second water passage group 12 are spaced apart on the axial sidewall of the outer cylinder 1. Both the first and second water passage groups 11 and 12 include at least three water passage pipes spaced apart in the circumferential direction of the outer cylinder 1. The valve core 2 is rotatably disposed within the outer cylinder 1. The valve core 2 has a first connecting groove 21 corresponding to the position of the first water passage group 11 and a second connecting groove 22 corresponding to the position of the second water passage group 12. The first connecting groove 21 can connect at least two adjacent water passage pipes in the first water passage group 11, and the second connecting groove 22 can connect at least two adjacent water passage pipes in the second water passage group 12. When the valve core 2 rotates relative to the outer cylinder 1, the first connecting groove 21 and / or the second connecting groove 22 can switch to connect to different adjacent water passage pipes in their corresponding water passage groups.

[0030] In this design, a first water passage group 11 and a second water passage group 12 are connected at intervals on the side wall of the outer cylinder 1 in the axial direction. The valve core 2 is rotatably disposed inside the outer cylinder 1. The valve core 2 is provided with a first connecting groove 21 corresponding to the position of the first water passage group 11 and a second connecting groove 22 corresponding to the position of the second water passage group 12. The first connecting groove 21 can connect at least two adjacent water passage pipes in the first water passage group 11, and the second connecting groove 22 can connect at least two adjacent water passage pipes in the second water passage group 12. This arrangement forms a multi-way valve with two layers of at least three-way valves combined together, and when the valve core 2 rotates relative to the outer cylinder 1, it can simultaneously drive the two layers of at least three-way valves, so that the first connecting groove 21 and / or the second connecting groove 22 can be switched to connect to different adjacent water passage pipes in their corresponding water passage groups. When the valve core 2 rotates relative to the outer cylinder 1, the first connecting groove 21 can switch to connect with different adjacent water pipes in its corresponding water passage group, or the second connecting groove 22 can switch to connect with different adjacent water pipes in its corresponding water passage group, or both the adjacent water pipes connected to the first connecting groove 21 and the second connecting groove 22 can change. A servo motor connected to the valve core 2 determines the rotation of the valve core 2 relative to the outer cylinder 1, thereby switching the connection between the first connecting groove 21 and / or the second connecting groove 22 and different adjacent water pipes in its corresponding water passage group. This single-valve-body layered multi-way water valve achieves a "one valve body for two valves" structure, solving the cross-contamination problem of existing single-layer multi-way valves when connecting two different water tanks, and reducing the need for a drive device, thus reducing the space occupied by other vehicle components.

[0031] In this example, the valve core 2 is rotatably disposed inside the outer cylinder 1, and the valve core 2 and the outer cylinder 1 are sealed.

[0032] Taking the first water passage group 11 and the second water passage group 12 as examples, each of which includes three water passage pipes, the three water passage pipes included in the first water passage group 11 are water passage pipe A, water passage pipe B and water passage pipe C, and the three water passage pipes included in the second water passage group 12 are water passage pipe D, water passage pipe E and water passage pipe F. Water passage pipes A, B, C, D, E and F are respectively the ports A, B, C, D, E and F of the six-way valve in the figure.

[0033] When the multi-port water valve is a six-port valve, and the six-port valve includes, for example: Figure 1When connecting ports A, B, C, D, E, and F, the following multiple modes are included: First mode: the F water pipe is connected to the D water pipe via the second connecting groove 22, and the A water pipe is connected to the C water pipe via the first connecting groove 21; Second mode: as shown in the figure, rotating the valve core 2 counterclockwise connects the F water pipe to the D and E water pipes via the second connecting groove 22, and the A and B water pipes via the first connecting groove 21; Third mode: as shown in the figure, continuing to rotate the valve core 2 counterclockwise connects the F water pipe to the D... In the first mode, the water pipes are connected to each other via the second connecting groove 22, and the water pipes A, B, and C are connected via the first connecting groove 21. In the second mode, the valve core 2 is rotated counterclockwise to connect the water pipes F, D, and E via the second connecting groove 22, and the water pipes A and B via the first connecting groove 21. In the third mode, the valve core 2 is rotated counterclockwise to switch the connection between the water pipes F and E via the second connecting groove 22, and the water pipes A and B via the first connecting groove 21.

[0034] In addition, the valve core 2 can be an integral valve core or a segmented valve core; in this example, a segmented valve core is used, with the two valve core segments fixedly connected. The first connecting groove 21 and the second connecting groove 22 are respectively located on the side walls of the two valve core segments. The drive shaft is connected to the valve core, and the entire valve core 2 can be rotated relative to the outer cylinder 1 by a servo motor, thereby switching the connection between the first connecting groove 21 and / or the second connecting groove 22 and different adjacent water pipes in their corresponding water channel groups.

[0035] In some optional embodiments, the valve core 2 includes an inner cylinder 20 and support frames 23 disposed at both ends of the inner cylinder 20. A first connecting groove 21 and a second connecting groove 22 are disposed on the side wall of the inner cylinder 20, and the first connecting groove 21 and the second connecting groove 22 are spaced apart in the axial direction of the inner cylinder 20.

[0036] In this embodiment, the valve core 2 is designed to include an inner cylinder 20 and support frames 23 disposed at both ends of the inner cylinder 20. The support frames 23 can ensure the strength of the inner cylinder 20. The support frames are mesh structures, which can reduce the overall weight. The first connecting groove 21 and the second connecting groove 22 are connecting grooves formed by indentation in the side wall of the inner cylinder 20. The inner cylinder 20 is a hollow cylinder. The first connecting groove 21 and the second connecting groove 22 are spaced apart in the axial direction of the inner cylinder 20, which makes it difficult for the water flowing in the first connecting groove 21 and the second connecting groove 22 to exchange heat. Cold water and hot water will not have temperature cross-contamination, thereby avoiding additional energy consumption in the hot water circuit and the cold water circuit.

[0037] In this example, the drive shaft of the servo motor of the multi-way water valve is connected to the support frame 23, thereby driving the valve core 2 to rotate. If the valve core 2 is a segmented valve core, the segmented valve core is a two-section hollow cylinder, and each hollow cylinder has a support frame at both ends. The first connecting groove 21 and the second connecting groove 22 are connecting grooves formed by the inward indentation of the inner cylinder 20 side wall of each hollow cylinder.

[0038] Figure 4 This is a schematic diagram of the sealing sleeve in the multi-way water valve in an embodiment of the present invention; as shown. Figure 4 As shown, in some optional embodiments, a sealing sleeve 3 is provided between the inner cylinder 20 and the outer cylinder 1. The sealing sleeve 3 can rotate relative to the inner cylinder 20 and is relatively fixed in position relative to the outer cylinder 1. The sealing sleeve 3 is provided with a water passage hole 33 corresponding to the water passage pipe.

[0039] In this embodiment, a sealing sleeve 3 is provided between the inner cylinder 20 and the outer cylinder 1 to improve the sealing performance between the inner cylinder 20 and the outer cylinder 1. A water passage hole 33 corresponding to the water passage pipe is provided on the sealing sleeve 3, and the sealing sleeve 3 can rotate relative to the inner cylinder 20, while its position relative to the outer cylinder 1 is fixed. In this way, when the valve core 2 rotates, the first connecting groove 21 and the second connecting groove 22 are connected to the water passage pipe through the corresponding water passage hole 33.

[0040] In some alternative embodiments, the cross-section of the water passage 33 is rectangular.

[0041] In this embodiment, the water passage 33 is designed with a rectangular cross-section, which allows for more linear flow regulation when switching water passages by rotating the valve core 2, without sudden increases. This makes it convenient to control the flow rate by rotating the valve core 2.

[0042] In some optional embodiments, a sealing ring 31 is provided between the first connecting groove 21 and the second connecting groove 22 in the axial direction of the inner cylinder 20, and the sealing ring 31 is located between the inner cylinder 20 and the sealing sleeve 3.

[0043] In this embodiment, a sealing ring 31 is provided between the inner cylinder 20 and the sealing sleeve 3, and the sealing ring 31 is located on the outside of the inner cylinder 20 between the first connecting groove 21 and the second connecting groove 22. This can improve the sealing between the first connecting groove 21 and the second connecting groove 22 and prevent cross-flow of fluids in the first connecting groove 21 and the second connecting groove 22, thus avoiding heat exchange.

[0044] In addition, a circumferential limiting groove is provided on the inner wall of the sealing sleeve 3. The limiting groove is used to install the sealing ring 31 and restrict the movement of the sealing ring 31 in the axial direction.

[0045] In some optional embodiments, the inner sidewall of the sealing sleeve 3 is provided with a plurality of axial sealing strips 32 at intervals, and abuts against the outer sidewall of the inner cylinder 20.

[0046] In this embodiment, a sealing strip 32 is provided on the inner side wall of the sealing sleeve 3, which abuts against the outer side wall of the inner cylinder 20, thereby improving the sealing performance between the sealing sleeve 3 and the inner cylinder 20. Additionally, in this example, at least one axial sealing strip 32 is provided between adjacent water passage holes 33 to prevent water leakage between the disconnected and connected water passage pipes when switching the connection state between the first connecting groove 21 and the second connecting groove 22 and the water passage pipe.

[0047] In some alternative embodiments, the first water passage group 11 and the second water passage group 12 are symmetrically arranged along the radial plane of the outer cylinder 1.

[0048] In this embodiment, the first water passage group 11 and the second water passage group 12 are symmetrically arranged along the radial plane of the outer cylinder 1 through the axis, and the water passage pipes in the first water passage group 11 and the second water passage group 12 are spaced apart. This design makes it convenient for the entire valve body to be installed in the vehicle.

[0049] In some alternative embodiments, both the first water passage group 11 and the second water passage group 12 include three water passage pipes.

[0050] In this embodiment, the first water passage group 11 includes three water passage pipes, namely water passage pipe A, water passage pipe B, and water passage pipe C; the second water passage group 12 includes three water passage pipes, namely water passage pipe D, water passage pipe E, and water passage pipe F. Water passage pipes A, B, C, D, E, and F are respectively... Figure 3 and 5 Ports A, B, C, D, E, and F in a six-way valve.

[0051] In some alternative embodiments, the length of the first connecting groove 21 in the circumferential direction is less than the length of the second connecting groove 22 in the circumferential direction.

[0052] In this embodiment, the spacing between the A, B, and C water pipes in the first water passage group 11 in the circumferential direction, and the spacing between the D, E, and F water pipes in the second water passage group 12 in the circumferential direction are reasonably designed.

[0053] In this example, the circumferential spacing between water pipes A, B, and C in the first water passage group 11 is smaller than the circumferential spacing between water pipes D, E, and F in the second water passage group 12.

[0054] This can be achieved as follows: In electric drive cooling mode, water pipes F, D, and E are connected via the second connecting groove 22, and water pipes A and B are connected via the first connecting groove 21; when switching to crew compartment heating + battery cooling mode, rotating valve core 2 connects water pipes F, D, and E via the second connecting groove 22, and water pipes A, B, and C via the first connecting groove 21; when switching back to crew compartment cooling (defogging) + battery heating mode, rotating valve core... 2. Connect water pipes F, D, and E through the second connecting groove 22, and connect water pipes A and C through the first connecting groove 21. In other modes, the connection can be changed so that water pipes F and E are connected through the second connecting groove 22, and water pipes A and B are connected through the first connecting groove 21. Alternatively, rotate valve core 2 to connect water pipes F and D through the second connecting groove 22, and water pipes A and C through the first connecting groove 21.

[0055] In other embodiments, a third connecting groove can be provided in the same circumferential direction as the inner cylinder 20 and the first connecting groove 21. The third connecting groove is located in the same axial position as the first water passage group 11 in the axial direction. The first connecting groove 21 and the third connecting groove are not connected and have different lengths. A fourth connecting groove can be provided in the same circumferential direction as the inner cylinder 20 and the second connecting groove 22. The fourth connecting groove is located in the same axial position as the second water passage group 12 in the axial direction. The second connecting groove 22 and the fourth connecting groove are not connected and have different lengths. This design allows the valve core 2 to be rotated 180 degrees when the multi-way water valve needs to switch to another state, so that the third connecting groove corresponds to the position of the first water passage group 11 and the fourth connecting groove corresponds to the position of the second water passage group 12, making it suitable for other usage environments.

[0056] On the other hand, the present invention also provides a vehicle including any of the above-mentioned multi-way water valves.

[0057] After the multi-way valve is installed on the vehicle, a first water passage group 11 and a second water passage group 12 are connected at intervals on the side wall of the outer cylinder 1 in the axial direction. The valve core 2 is rotatably disposed inside the outer cylinder 1. The valve core 2 is provided with a first connecting groove 21 corresponding to the position of the first water passage group 11 and a second connecting groove 22 corresponding to the position of the second water passage group 12. The first connecting groove 21 can connect at least two adjacent water passage pipes in the first water passage group 11, and the second connecting groove 22 can connect at least two adjacent water passage pipes in the second water passage group 12. This arrangement forms a multi-way valve with two layers of at least three-way valves combined together, and when the valve core 2 rotates relative to the outer cylinder 1, it can drive the two layers of at least three-way valves at the same time, so that the first connecting groove 21 and / or the second connecting groove 22 can be switched to connect to different adjacent water passage pipes in their corresponding water passage groups. When the valve core 2 rotates relative to the outer cylinder 1, the first connecting groove 21 can switch to connect with different adjacent water pipes in its corresponding water passage group, or the second connecting groove 22 can switch to connect with different adjacent water pipes in its corresponding water passage group, or both the adjacent water pipes connected to the first connecting groove 21 and the second connecting groove 22 can change. A servo motor connected to the valve core 2 determines the rotation of the valve core 2 relative to the outer cylinder 1, thereby switching the connection between the first connecting groove 21 and / or the second connecting groove 22 and different adjacent water pipes in its corresponding water passage group. This single-valve-body layered multi-port water valve achieves a "one valve body for two valves" structure, solving the cross-contamination problem when connecting two different water tanks using a single-layer multi-port valve in existing vehicles, and reducing the need for a drive device, thus reducing the space occupied by other vehicle components.

[0058] The valve core 2 is designed to include an inner cylinder 20 and support frames 23 at both ends of the inner cylinder 20. The support frames 23 can ensure the strength of the inner cylinder 20. The support frames are mesh structures, which can reduce the overall weight. The first connecting groove 21 and the second connecting groove 22 are connecting grooves formed by inward indentation on the side wall of the inner cylinder 20. The inner cylinder 20 is a hollow cylinder. The first connecting groove 21 and the second connecting groove 22 are spaced apart in the axial direction of the inner cylinder 20, which makes it difficult for the water flowing in the first connecting groove 21 and the second connecting groove 22 to exchange heat. Cold water and hot water will not have temperature cross-contamination, thereby avoiding additional energy consumption in the hot water circuit and the cold water circuit.

[0059] A sealing sleeve 3 is provided between the inner cylinder 20 and the outer cylinder 1 to improve the sealing between the inner cylinder 20 and the outer cylinder 1. The water passage 33 is designed with a rectangular cross-section, so that when the valve core 2 is rotated and the water passage pipe is switched, the flow rate adjustment is more linear and will not suddenly increase. It is convenient to control the flow rate by rotating the valve core 2.

[0060] A sealing ring 31 is provided between the inner cylinder 20 and the sealing sleeve 3, which can improve the sealing between the first connecting groove 21 and the second connecting groove 22, and prevent cross-flow of fluids in the first connecting groove 21 and the second connecting groove 22, thus preventing heat exchange.

[0061] At least one axial sealing strip 32 is provided between adjacent water passage holes 33 to prevent water leakage between the unconnected water passage pipe and the connected water passage pipe when switching the connection state between the first connecting groove 21 and the second connecting groove 22 and the water passage pipe.
