[0035] like Figures 1 to 7 As shown, according to the first aspect of the present invention, a three-way electronic water valve for vehicles is provided, which includes a valve body 1, a valve core 2, and an actuator 3.

[0036] In the following description, reference will be made to Figures 1 to 7 The specific structure of the aforementioned components of the three-way electronic water valve for vehicles and the connection relationship of the aforementioned components are described in detail.

[0037] like Figures 1 to 7 As shown, in the embodiment, the first side of the valve body 1 (which can be as follows) Figure 5 The left side of the valve body 1 shown can be provided with a first outlet valve 11, and the second side of the valve body 1 can be as follows: Figure 5The valve body 1 shown can be provided with an inlet valve 10 on its middle side, and the valve body 1 can be provided with a third side (such as...). Figure 5 A second outlet valve port 12 can be provided on the right side of the valve body 1 shown. A valve core 2 can be disposed inside the valve body 1. A flow channel 20 can be formed on the outer periphery of the valve core 2. The inlet valve port 10 can be connected to the first outlet valve port 11 and / or the second outlet valve port 12 through the flow channel 20. An actuator 3 is mounted on the top of the valve body 1. The actuator 3 can be drivenly connected to the valve core 2 to drive the valve core 2 to rotate. The actuator 3 thereby adjusts the degree of connection between the inlet valve port 10 and the first outlet valve port 11 and the second outlet valve port 12, thereby enabling multiple flow modes and regulating the water flow rate.

[0038] Preferred, such as Figure 1 , Figure 2 and Figure 4 As shown, in this embodiment, a valve cavity for accommodating the valve core 2 can be formed inside the valve body 1. The valve core 2 is installed in the valve cavity and partially passes through the valve body 1. The valve body 1 may have a bottom opening. The three-way electronic water valve for vehicles may also include a valve cover 4, which can be sealed and welded to the bottom opening of the valve body 1. Alternatively, the valve cover may also be installed at the bottom of the valve body by means of a sealing ring and bolts.

[0039] Preferred, such as Figure 1 , Figure 2 and Figures 5 to 7 As shown, in this embodiment, valve ports communicating with the valve cavity can be provided on three sides of the valve body 1. The inlet valve port 10 can be located between the first outlet valve port 11 and the second outlet valve port 12. Preferably, the angle between the axis of the inlet valve port 10 and the axis of the first outlet valve port 11 can be 90°, and the angle between the axis of the inlet valve port 10 and the axis of the second outlet valve port 12 can also be 90°. The first outlet valve port 11 and the second outlet valve port 12 can be located on opposite sides of the valve body 1. Preferably, the inlet valve port 10, the first outlet valve port 11, and the second outlet valve port 12 can be designed with pipe joints, allowing the valve ports to be directly connected to water pipes in the thermal management system. However, this is not a limitation; the inlet valve port, the first outlet valve port, and the second outlet valve port can also adopt a flange-type mounting structure to communicate with the thermal management system.

[0040] Preferred, such as Figures 1 to 7As shown, in this embodiment, the valve core 2 can be a spherical valve core. A vertical valve core shaft 24 can be provided at the top of the valve core 2. A shaft hole 14 for the valve core shaft 24 to pass through can be formed at the top of the valve body 1. The valve core shaft 24 can partially extend out of the shaft hole 14. A spline 25 can be provided at the top of the valve core shaft 24, and the valve core shaft 24 can be connected to the actuator 3 via the spline 25. A motor can be installed inside the actuator 3 to drive the valve core 2 to rotate. The actuator 3 can be fixedly mounted on the top of the valve body 1 with bolts. The actuator 3 can adjust the degree of connection between the valve ports by rotating the valve core 2 to achieve multiple flow modes.

[0041] Furthermore, preferably, such as Figure 1 and Figure 3 As shown, in this embodiment, the valve body 1 may be provided with a first mounting seat 15 at the shaft hole 14. An annular mounting groove may be formed on the first mounting seat 15. A shaft seal 150 may be installed in the mounting groove. This arrangement allows the shaft seal 150 to be fitted around the outer periphery of the valve core shaft 24 when the valve core shaft 24 passes through the shaft hole 14, thereby providing a sealing function to prevent liquid in the valve cavity from flowing into the actuator 3 and causing damage to the actuator 3.

[0042] In addition, preferred, such as Figure 1 and Figure 4 As shown, in this embodiment, a rotating shaft 41 can be installed in the middle of the valve cover 4, and the valve core 2 can be installed on the rotating shaft 41. Specifically, an annular second mounting seat 40 can be formed in the middle of the valve cover 4. The bottom end of the rotating shaft 41 can be inserted into the second mounting seat 40. A cylindrical groove can be formed at the bottom of the valve core 2, and the rotating shaft 41 and the second mounting seat 40 can be inserted into the cylindrical groove, so that the valve core 2 can rotate around the axis of the rotating shaft 41.

[0043] Preferred, such as Figure 1 and Figure 3 As shown, in this embodiment, the flow channel 20 can be formed on the circumferential side of the valve core 2 (i.e., on the side of the valve core 2 facing the valve port), and the flow channel 20 can be formed only on half of the circumference of the valve core 2. The flow channel 20 can be an arc-shaped groove formed on the surface of the valve core 2, and the cross-section of the flow channel 20 can be U-shaped. The outer wall of the valve core 2 and the flow channel 20 can be transitioned by rounded corners.

[0044] Further optimized, such as Figure 1 and Figure 3As shown, in this embodiment, the valve core 2 may be provided with a grid-like reinforcing rib 23 at its top to improve the strength of the valve core 2. Furthermore, a first protrusion 21 and a second protrusion 22 may be formed on two of the reinforcing ribs 23, and a protruding stop point 13 may be provided on the inner surface of the valve body 1. This arrangement ensures that when the valve core 2 rotates a certain angle (i.e., when the valve core 2 rotates to a preset limit position), the stop point 13 can abut against the first protrusion 21 or the second protrusion 22, thereby limiting the maximum rotation range of the valve core 2.

[0045] Preferred, such as Figures 5 to 7 As shown, in this embodiment, the three-way electronic water valve for the vehicle may include three flow modes. Specifically, the preset rotation angle (less than the maximum rotation angle) of the valve core 2 may include 0° to 72°.

[0046] When the valve core 2 rotates to 0°, the three-way electronic water valve for the vehicle is in the first flow mode. In this case, the inlet valve port 10 is only connected to the first outlet valve port 11. Water enters through the inlet valve port 10, the second outlet valve port 12 is closed, and water exits through the first outlet valve port 11.

[0047] When the valve core 2 rotates to 36°, the three-way electronic water valve for the vehicle is in the second flow mode. In this case, the inlet valve 10 is connected to the first outlet valve 11 and the second outlet valve 12. Water enters through the inlet valve 10, and the first outlet valve 11 and the second outlet valve 12 each discharge water at a 50% ratio.

[0048] When the valve core 2 rotates to 72°, the three-way electronic water valve for the vehicle is in the third flow mode. In this case, the inlet valve port 10 is only connected to the second outlet valve port 12. Water enters through the inlet valve port 10, the first outlet valve port 11 is closed, and water exits through the second outlet valve port 12.

[0049] This enables the implementation of multiple flow modes required in the vehicle's thermal management system. Furthermore, by adjusting the rotation angle of the valve core 2, the water output ratio between the first outlet valve 11 and the second outlet valve 12 can be adjusted, thereby regulating the water flow rates of the first outlet valve 11 and the second outlet valve 12. Simultaneously, this configuration results in a smaller pressure difference between the first outlet valve 11 and the second outlet valve 12, thus minimizing the impact of flow resistance on the coolant flow rate within the valve body 1.

[0050] In addition, preferred, such as Figure 1 , Figure 2 and Figure 4As shown, in this embodiment, the three-way electronic water valve for vehicles may further include a sealing part to enhance the sealing performance of the outlet valve when it is in the closed state, thereby reducing liquid leakage. The sealing part may include a limiting support 51, a sealing valve seat 52, and a limiting groove 53. The limiting support 51 may be disposed on the valve cover 4. The upper surface of the limiting support 51 may be formed as an arc shape. The sealing valve seat 52 may be formed as an annular shape and may be installed on the arc shape of the limiting support 51. The sealing valve seat 52 can contact the valve core 2 and the inner surface of the valve body 1. The limiting groove 53 may be formed on the inner surface of the valve body 1 and may be disposed directly above the limiting support 51, such that the limiting groove 53 corresponds to the position of the limiting support 51. When the sealing valve seat 52 is installed on the limiting support 51, the top of the sealing valve seat 52 can be precisely engaged within the limiting groove 53, thereby achieving positioning of the sealing valve seat 52.

[0051] Furthermore, preferably, such as Figure 1 , Figure 2 and Figure 4 As shown, in this embodiment, there can be two sealing parts. The two sealing parts can be respectively located at the first water outlet 11 and the second water outlet 12 to reduce internal leakage. Through these two sealing parts, the three-way electronic water valve for the vehicle can achieve a leakage rate of less than 5.3 ml / min when the water outlet is closed under 60 kPa conditions. More preferably, the sealing valve seat 52 can be made of ethylene propylene rubber, and a polytetrafluoroethylene layer is provided on the side facing the valve core 2 to reduce friction, thereby allowing the valve core 2 to rotate rapidly within the valve body 1 to quickly adjust the flow rate. The valve body 1, valve cover 4, valve core 2, and actuator 3 can be made of engineering plastics to reduce the overall vehicle weight.

[0052] Furthermore, according to a second aspect of the present invention, a vehicle is provided, the vehicle including the three-way electronic water valve for vehicles as described above.

[0053] During use, the three-way electronic water valve for the vehicle can drive the valve core 2 to rotate via the actuator 3, thereby adjusting the connection between the inlet valve port 10, the first outlet valve port 11, and the second outlet valve port 12, thus realizing multiple flow modes. This enables the diversion of water in the vehicle's thermal management system and the control of the heat exchange water flow, thereby improving the thermal efficiency of the entire vehicle's thermal management system.

[0054] Finally, it should be noted that the above-described embodiments are merely specific implementations of this application, used to illustrate the technical solutions of this application, and not to limit them. The protection scope of this application is not limited thereto.
