Description

Technical Field

[0001] This utility model relates to the field of thermal management technology for new energy vehicles, specifically to an electronic water valve. Background Technology

[0002] Currently, with the improvement of people's living standards, private cars have become an indispensable means of transportation for most families. Since petroleum is a non-renewable energy source, new energy vehicles are gradually becoming the mainstream mode of transportation. The drive motors of new energy vehicles require high power and high speed, which generates a large amount of heat during high-speed driving. If this heat is not dissipated in time, it will seriously affect the performance and lifespan of the motor. Furthermore, to improve range, automakers often choose power batteries with high energy density and high discharge rate. However, excessively high energy density and discharge rate inevitably cause the battery to generate a large amount of heat during use. Excessive temperature not only affects battery life but also easily leads to safety accidents.

[0003] In the thermal management system of new energy vehicles, it is necessary to control the different temperature requirements of functional areas such as the battery, motor, electronic control, and passenger compartment. The coolant circulates in real time between different loops according to the demand, and maintains each functional area within the target temperature range through heat exchange. The thermal management system generally uses multiple electric valves to control multiple flow paths of the system. How to design electric valves so that a single electronic water valve can handle the control of different flow paths of the system, thereby reducing the system's footprint, is a technical problem that needs to be improved.

[0030] Example 1

[0031] like Figures 1 to 4 As shown, an electronic water valve in the first aspect embodiment of the present invention includes a valve body 1, a valve cover 2, a valve disc 3, a valve stem 4 and a drive mechanism. The valve body 1 is provided with a valve cavity, and the valve body 1 is provided with an inlet pipe 13 and a plurality of outlet pipes. The inlet pipe 13 is arranged along the axis of the valve cavity, and both the inlet pipe 13 and the outlet pipes are connected to the valve cavity.

[0032] The valve disc 3 is rotatably mounted in the valve cavity along the axis of the valve cavity. The valve disc 3 is provided with an inlet and an outlet, which are connected. The inlet is set along the axis of the valve cavity and is connected to the inlet pipe 13. The outlet is set correspondingly to the outlet pipe. Specifically, the outlet is set in a direction perpendicular to the axis of the inlet, and the diameter of the outlet is larger than the diameter of the outlet pipe. Rotating the valve disc 3 can control the switching of coolant between two adjacent outlet pipes. During the rotation of the valve disc 3, when the coolant flow rate in one outlet pipe decreases, the coolant flow rate in the adjacent outlet pipe increases.

[0033] The valve stem 4 is vertically arranged along the axis of the valve disc 3, and the bottom end of the valve stem 4 is connected to the valve disc 3. The valve stem 4 and the valve disc 3 are integrally injection molded structures.

[0034] The valve cover 2 is located on the top of the valve body 1. Specifically, the valve cover 2 and the valve body 1 are connected by screws 22, and a sealant is provided between the valve cover 2 and the valve body 1. The drive mechanism is located inside the valve cover 2, and the output end of the drive mechanism is connected to the top of the valve stem 4.

[0035] In this embodiment, it should be noted that the valve body 1 is provided with a connecting ear 11, which is an integral structure with the valve body 1. The connecting ear 11 is provided with multiple connecting holes, and each connecting hole is provided with a shock-absorbing sleeve 12. The connecting ear 11 can be used in conjunction with the connecting holes to quickly install and fix the entire electronic valve. By setting the shock-absorbing sleeve 12, vibration and noise can be effectively reduced.

[0036] like Figure 2 and Figure 3As shown, the valve body 1 adopts an integrated design. The valve body 1 is provided with a first liquid outlet pipe 14, a second liquid outlet pipe 15 and a third liquid outlet pipe 16. The first liquid outlet pipe 14, the second liquid outlet pipe 15 and the third liquid outlet pipe 16 are all arranged in a direction perpendicular to the liquid inlet pipe 13.

[0037] The technical effect achieved by this embodiment is that multiple outlet pipes are provided, and the control of multi-flow coolant can be realized by using a single electronic water valve. This can effectively reduce the number of electronic valves used in the thermal management system, thereby reducing the overall system volume and making the thermal management system structure more compact.

[0038] Example 2

[0039] like Figures 1 to 4 As shown, another electronic water valve provided in this embodiment has the same structure as in Embodiment 1. Only the different parts are described below.

[0040] In this embodiment, sealing components 9 are respectively provided between the top and bottom of the valve disc 3 and the valve body 1.

[0041] In this embodiment, it should be noted that, as Figure 4 As shown, the sealing assembly 9 includes a support ring 24 and a second sealing ring 23. The second sealing ring 23 includes an outer ring and an inner ring. The inner ring is arranged in a direction perpendicular to the axial direction of the outer ring. The inner ring and the outer ring are an integral structure. The diameter of the inner ring is smaller than the diameter of the outer ring.

[0042] The support ring 24 is set on the inner ring, and one end of the support ring 24 abuts against one side of the outer ring, while the other side of the outer ring abuts against the valve disc 3.

[0043] The technical effect achieved by this embodiment is that by setting the sealing component 9, a spherical contact is formed between the sealing component 9 and the valve disc 3, which can effectively ensure the sealing performance between the valve disc and the valve body and prevent leakage during use.

[0044] Example 3

[0045] like Figures 1 to 4 As shown, another electronic water valve provided in this embodiment has the same structure as in Embodiment 1. Only the different parts are described below.

[0046] In this embodiment, the valve stem 4 is provided with two first sealing rings 8, which are arranged sequentially along the length direction of the valve disc 3 to form a double seal and prevent leakage along the valve stem direction during use.

[0047] In this embodiment, it should be noted that the valve body 1 is provided with a drain hole 10. The drain hole 10 is arranged in a direction perpendicular to the valve stem 4. The drain hole penetrates the side wall of the valve body 1 and is located between two sealing rings. By providing the drain hole 10, when coolant leakage occurs along the valve stem direction during use, the coolant can be discharged along the drain hole 10 to prevent coolant from entering the valve cover 2 and damaging electronic components.

[0048] Example 4

[0049] like Figures 1 to 4 As shown, another electronic water valve provided in this embodiment has the same structure as in Embodiment 1. Only the different parts are described below.

[0050] In this embodiment, as Figure 1 and Figure 2 As shown, the drive mechanism includes a motor 5 and a reduction mechanism.

Specifically, the motor 5 and the worm gear 17 are interference-fitted.

[0052] The output gear 6 is equipped with a displacement sensor 7, and the valve cover 2 is equipped with a detector. The detector and the displacement sensor 7 are set in correspondence. During use, the detector can determine the status of the electronic valve by identifying the position of the displacement sensor 7. During operation, the detector and the motor 5 are both connected to the VCU (Vehicle Control Unit).

[0053] The first double gear 19 and the second double gear 21 are rotatably mounted inside the valve cover 2 via the first rotating shaft 18 and the second rotating shaft 20, respectively. The worm gear 17 meshes with the large gear of the first double gear 19, the small gear of the first double gear 19 meshes with the large gear of the second double gear 21, and the small gear of the second double gear 21 meshes with the output gear 6.

[0054] The technical effect achieved by this embodiment is as follows: the reduction mechanism includes a first double gear 19 and a second double gear 21. The first double gear 19 and the second double gear 21 cooperate with each other to form a two-stage reduction. When used with the motor 5 and the worm gear 17, it can provide sufficient driving force and stably control the rotation of the valve disc 3, thus ensuring the stable operation of the entire electronic valve.

[0055] Although the present invention has been described in detail above with general descriptions and specific embodiments, some modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, all such modifications or improvements made without departing from the spirit of the present invention fall within the scope of protection claimed by the present invention.
