Description

Technical Field

[0001] The present application relates to the technical field of vehicle parts, and in particular to a water valve assembly and a vehicle. Background Art

[0002] An electronic water valve is a water valve device based on electronic control. It drives the opening and closing of the valve through electronic signals to control and regulate the water flow.

[0003] Existing water valves generally have elastic parts between the valve core and the valve cover. Such a structure makes the elastic parts stay in a high and low temperature alternating load environment for a long time. Secondly, the elastic parts are in a coolant environment for a long time, which places high requirements on the temperature resistance and corrosion resistance of the elastic parts. In addition, after long-term use in such an environment, the performance of the elastic parts will be greatly attenuated, resulting in a decrease in the sealing performance of the valve after durability. In addition, the arrangement of the elastic parts inside the valve will destroy the connection stability of the valve cover and the valve body during disassembly and maintenance.

[0004] Therefore, it is necessary to design a water valve assembly that is easy to disassemble and assemble, easy to maintain, has lower cost, and has lower requirements on elastic parts. Utility Model Content

[0005] The present application provides a water valve assembly and a vehicle, wherein the elastic parts in the water valve assembly are convenient to assemble and disassemble, easy to maintain, lower in cost, and have lower performance requirements.

[0039] Next, the embodiments of this specification are described in detail.

[0040] Reference Figure 1 As shown, this embodiment discloses a water valve assembly, which includes a valve 10, an actuator 20 and an elastic member 30. The elastic member 30 is arranged outside the valve 10, that is, between the valve cover 12 and the actuator 20, which is convenient for disassembly and maintenance.

[0041] In addition, since the elastic member 30 is arranged outside the valve 10, the elastic member 30 is prevented from being in a coolant environment and a high and low temperature alternating load environment, and the requirements for the performance of the elastic member 30 itself are reduced, and corrosion of the elastic member is avoided, and the cost of the elastic member can also be reduced.

[0042] Reference Figure 1 As shown, the valve 10 includes a valve body 11, a valve cover 12 covered on the valve body 11, and a valve core 13 accommodated in the valve body 11 and the valve cover 12, and the output end 131 of the valve core 13 extends out of the valve cover 12. In addition, the actuator 20 is covered on the valve cover 12 and connected to the output end 131, and the actuator 20 drives the rotation of the valve core 13 to realize the switching of different flow paths, thereby forming different liquid flow paths.

[0043] The water valve assembly further includes an elastic member 30, which is sleeved on the output end 131 and disposed between the valve cover 12 and the actuator 20. The actuator 20 initially compresses the elastic member 30, and transmits the force on the elastic member 30 to the valve core 13 through the bracket 40, so that the valve core 13 presses against the second sealing member 52, and the second sealing member 52 forms an end face contact seal with the valve body 11.

[0044] Specifically, refer to Figure 5 As shown, the water valve assembly also includes a bracket 40, and the top of the valve cover 12 is provided with a bracket matching groove 121 adapted to the bracket 40; the bracket 40 is provided with an installation groove 41; the bracket 40 is accommodated in the bracket matching groove 121, and the elastic member 30 is accommodated in the installation groove 41.

[0045] In addition, the bottom of the actuator 20 abuts against the elastic member 30 , thereby ensuring that when the actuator 20 is compressed toward the valve core 13 , the force can be transmitted to the elastic member 30 , and the elastic member 30 then transmits the force to the bracket 40 .

[0046] The elastic member 30 is a wave spring. The advantage of this design is that it can increase the contact area between the bottom of the actuator 20 and the elastic member 30, thereby making the force-bearing area on the elastic member 30 larger and more uniform; and it can also increase the service life of the elastic member 30. Of course, what is described here is only one structure that can be implemented for the elastic member 30, and it is not limited to this.

[0047] Further, refer to Figure 4-5 As shown, the side wall of the bracket matching groove 121 is provided with slots 1211 at intervals, and the side edge of the corresponding bracket 40 is provided with a convex rib 42 adapted to the slots 1211, and the convex rib 42 is accommodated in the slots 1211. In this way, the bracket 40 can only move axially, which limits the circumferential rotation of the bracket 40, ensuring that the elastic member 30 will not be twisted and deformed when the valve core 13 rotates.

[0048] Reference Figure 6 As shown, the top of the valve core 13 also includes a support block 132, the output end 131 is connected to the support block 132, and the radial width of the output end 131 is smaller than the radial width of the support block 132, thereby forming a step surface of the support bracket 40 on the outside of the support block 132. In order to improve the overall structural strength of the valve core 13, in this embodiment, the support block 132 and the output end 131 are integrally formed.

[0049] Furthermore, the valve cover 12 is provided with a first through hole 122, and the bracket 40 is provided with a second through hole 43 coaxially arranged with the first through hole 122. When the valve core 13 is accommodated in the first through hole 122 and the second through hole 43, the top of the support block 132 protrudes from the top of the second through hole 43, and the top of the bracket 40 abuts against the actuator 20, and the bottom of the bracket 40 abuts against the support block 132. In this way, the bracket 40 can be supported on the step surface of the support block 132. At the same time, it is ensured that there is a distance between the bracket 40 and the top of the valve cover 12. That is, when the actuator 20 is initially compressed by the elastic member 30 and the force on the elastic member 30 is transmitted to the valve core 13 through the bracket 40, the bracket 40 can move up and down to avoid motion interference.

[0050] Reference Figure 2-3As shown, in one practicable manner, the outer wall of the valve cover 12 is provided with an annular step portion 124, and the bottom of the corresponding actuator 20 is provided with a ridge 21, and the ridge 21 abuts against the step portion 124. Therefore, there is an overlapped area between the outer wall of the valve cover 12 and the ridge 21, and the overlapped area can prevent dust and water droplets from splashing and contaminating the elastic member 30. Since the step portion 124 of the valve cover 12 is arranged in an annular shape, the corresponding ridge 21 is also arranged in an annular shape to increase the contact area with the step portion 124.

[0051] In another possible implementation, refer to Figure 7 As shown, the water valve assembly further includes a first sealing member 51 , which is arranged between the convex rib 21 and the valve cover 12 . The first sealing member 51 mentioned here may be a sealing ring.

[0052] It should be noted that the above are only two dust-proof structures that can be realized, and are not specifically limited here. Of course, both dust-proof structures can also exist in the water valve assembly at the same time to further improve the sealing performance of the water valve assembly.

[0053] Furthermore, the actuator 20 is provided with a first mounting portion 22, which corresponds to a second mounting portion 123 adapted to the top of the valve cover 12, and the first mounting portion 22 and the second mounting portion 123 are detachably connected. For example, they are detachably connected by screws. When the actuator 20 and the valve cover 12 are disassembled, the valve core 13 does not need to be disassembled, and the elastic member 30 can be directly taken out from the top of the valve cover 12 for replacement or installation, which is more convenient and quick.

[0054] In addition, refer to Figure 1 As shown, a third sealing member 53 is also provided at the connection between the valve cover 12 and the valve core 13. In this way, the water flow in the valve core 13 can be prevented from overflowing.

[0055] This embodiment also provides a vehicle, on which the above-mentioned water valve assembly is provided. Since the water valve assembly arranges the elastic member 30 outside the valve 10, that is, between the valve cover 12 and the actuator 20, it is convenient to disassemble and assemble and easy to maintain. In addition, since the elastic member 30 is arranged outside the valve 10, the elastic member 30 is prevented from being in a coolant environment and a high and low temperature alternating load environment, and the requirements for the performance of the elastic member 30 itself are reduced, and corrosion of the elastic member is avoided, and the cost of the elastic member can also be reduced.
