In addition, the terms "first", "second", etc. involved in the embodiments of the present application are only for the purpose of convenient description and cannot be understood as indicating or implying relative importance.

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

[0040] Referring to Figures 1-3 As shown, the present application discloses a water valve assembly, which includes a valve body 10, a valve cover 20, a valve core 30, a connecting shaft 40, a bracket 50, a wear-resistant ring 60, and an actuator 70. The valve body 10 and the valve cover 20 form a receiving cavity 11, and the valve core 30 is located in the receiving cavity 11. A convex rib is provided at the connection between the valve body 10 and the valve cover 20, and a groove adapted to the convex rib is provided on the corresponding valve cover 20. The valve body 10 is covered on the valve cover 20 by the adaptation of the convex rib and the groove.

[0041] The valve cover 20 is provided with a through hole 21, and a receiving groove 22 is provided at the top of the valve cover 20. The through hole 21 communicates with the receiving groove 22, and both the receiving groove 22 and the through hole 21 are located in the middle of the valve cover 20. An annular protrusion is formed upward at the top of the valve cover 20, and at the same time, the top of the valve cover 20 is recessed downward. The receiving groove 22 is formed by the above two parts.

[0042] Specifically, the receiving groove 22 includes a first through groove 221 and a second through groove 222 that are sequentially communicated. The annular protrusion at the top of the valve cover 20 forms the first through groove 221, and the top of the valve cover 20 is recessed downward to form the second through groove 222. The inner diameter of the first through groove 221 is smaller than the inner diameter of the second through groove 222. The wear-resistant ring 60 is arranged in the first through groove 221, and the bracket 50 is arranged in the second through groove 222.

[0043] One end of the connecting shaft 40 is fixed to the valve core 30. After the connecting shaft 40 passes through the through hole 21, it sequentially passes through the valve cover 20, the wear-resistant ring 60, and the bracket 50 and is fixed to the actuator 70. The rotation of the valve core 30 connected to the connecting shaft 40 is driven by the actuator 70 to realize the switching of different flow channels, thereby forming different liquid flow channels.

[0044] The connecting shaft 40 includes a first section 41, a second section 42, and a third section 43 that are sequentially connected from top to bottom. The outer diameters of the first section 41, the second section 42, and the third section 43 increase in sequence. A first step portion 44 is formed at the connection between the first section 41 and the second section 42.

[0045] The outer diameter of the annular abutting surface 442 is larger than the outer diameter of the first step portion 44. Thereby increasing the contact area between the bracket 50 and the wear-resistant ring 60 and reducing the friction force generated on the contact surface between the two.

[0046] The wear-resistant ring 60 is fitted between the connecting shaft 40 and the bracket 50. A first step portion 44 is provided on the connecting shaft 40, and a second step portion 441 adapted to the first step portion 44 and an annular abutting surface 442 in contact with the bracket 50 are provided on the wear-resistant ring 60.

[0047] Referring to Figures 4-5As shown, a bump 61 is provided at the bottom of the wear-resistant ring 60, and a groove 443 adapted to the bump 61 is provided circumferentially corresponding to the first step portion 44. The first step portion 44 and the wear-resistant ring 60 are fixed by the cooperation of the bump 61 and the groove 443.

[0048] In another embodiment, referring to Figures 6-7 As shown, a groove 443 is provided on the inner circumferential side wall of the wear-resistant ring 60, and a bump 61 adapted to the groove 443 is provided circumferentially corresponding to the first step portion 44. The first step portion 44 and the wear-resistant ring 60 are fixed by the cooperation of the bump 61 and the groove 443. Of course, the bump 61 and the groove 443 can also be provided at other positions of the connecting shaft 40 except the first step portion 44, and specific details are not limited here.

[0049] Referring to Figures 1-2 and Figure 4 As shown, the water valve assembly further includes a wear-resistant block 80, and the wear-resistant block 80 is arranged between the valve cover 20 and the valve core 30. Among them, a plurality of receiving portions 31 are provided at the edge of the valve core 30, and a plurality of reinforcing ribs 32 are further provided on the valve core 30, and the receiving portions 31 are connected to the reinforcing ribs 32.

[0050] The valve core 30 is arched, and a wear-resistant block 80 is installed in each receiving portion 31. In order to effectively improve the unstable phenomenon of the valve core 30, the plurality of receiving portions 31 are evenly distributed along the circumference of the valve core 30, and an annular pressing portion 24 extending towards the valve core 30 is provided on the inner wall of the valve cover 20, and the annular pressing portion 24 abuts against the wear-resistant block 80. When the valve core 30 drives the wear-resistant block 80 to rotate within the entire rotation range, the annular pressing portion 24 always and only abuts against the wear-resistant block 80. In another embodiment, the surface of the valve core 30 can also be a plane or concave downward, and specific details are not limited here.

[0051] The surface roughness of the wear-resistant ring 60 and the wear-resistant block 80 is less than that of the bracket 50, the connecting shaft 40, the valve core 30 and the valve cover 20. The surface roughness of the bracket 50, the connecting shaft 40, the valve core 30 and the valve cover 20 mentioned here refers to the roughness of the contact surfaces of the two components. Among them, the bracket 50, the connecting shaft 40, the valve core 30 and the valve cover 20 can be made of the same material or different materials, and the materials can be selected as hard materials such as steel and iron. The materials of the wear-resistant ring 60 and the wear-resistant block 80 can be selected as smooth and wear-resistant materials such as POM plastic.

[0052] The water valve assembly further includes a seal 90, which includes a first seal 91 and a second seal 92. Specifically, a third step portion 45 is formed at the connection between the second section 42 and the third section 43, and the third step portion 45 is located within the receiving cavity 11. A positioning rib 23 extending downward is provided at the bottom of the valve cover 20, and the positioning rib 23 abuts against the side wall of the third section 43. The first seal 91 abuts against the second step portion 441 and is placed between the side wall of the second section 42 and the positioning rib 23 to prevent water in the receiving cavity 11 from flowing out through the gap between the through hole 21 and the connecting shaft 40. The first seal 91 mentioned here may refer to a sealing ring.

[0053] The second seal 92 is arranged between the valve core 30 and the valve body 10. The second seal 92 mentioned here may refer to a sealing ring.

[0054] The water valve assembly further includes an elastic member 71, and the elastic member 71 is placed between the bracket 50 and the actuator 70. Specifically, an elastic member installation groove 51 is formed at the top of the bracket 50, and the elastic member 71 is placed within the elastic member installation groove 51 and is clamped between the bracket 50 and the actuator 70.

[0055] The above-mentioned elastic member 71 is a corrugated spring. The advantage of this design is that it can increase the contact area between the bottom of the actuator 70 and the elastic member 71, thereby making the force-bearing area on the elastic member 71 larger and more uniform, and it can also increase the service life of the elastic member 71. Of course, what is mentioned here is only one implementable structure of the elastic member 71, and it is not limited specifically to this.

[0056] This application also discloses a vehicle, on which the above-mentioned water valve assembly is provided, solving the problem of the decrease in the compression amount caused by the wear between the internal components of the water valve assembly during long-term operation, which ultimately leads to leakage. Specifically, the water valve assembly adds a wear-resistant ring 60 between the bracket 50 and the connecting shaft 40, transferring the friction between the bracket 50 and the connecting shaft 40 to the friction between the connecting shaft 40 and the wear-resistant ring 60. By utilizing the smooth and wear-resistant characteristics of the wear-resistant ring 60, the problem of the continuous reduction of the compression amount caused by the non-wear resistance between the bracket 50 and the connecting shaft 40 is solved.

[0057] The water valve assembly also adds a wear-resistant block 80 between the valve core 30 and the valve cover 20 to share the pressing force, and the valve core 30 is pressed tightly by the combined action of the bracket 50 and the wear-resistant block 80. In addition, the wear-resistant blocks 80 are evenly arranged circumferentially along the top edge of the valve core 30, effectively improving the unstable phenomenon of the valve core 30.

[0058] Considering that the size of the wear-resistant ring 60 accommodated in the first through groove 221 is smaller than the size of the bracket 50 accommodated in the second through groove 222, the inner diameter of the first through groove 221 in this application is smaller than the inner diameter of the second through groove 222, improving the space utilization rate. At the same time, since the size of the first through groove 221 is related to the structural strength of the valve cover 20, reducing the size of the first through groove 221 can improve the overall structural strength of the valve cover 20.

[0059] It should be noted that the technical solutions or technical features described in the above embodiments can be combined or supplemented with each other without conflict. The scope of protection of this application is not limited to the precise structures described in the above embodiments and shown in the drawings; all modifications, equivalent replacements, improvements, etc. made within the spirit and principles of this application shall be included within the scope of protection of this application.
