[0042] Water pumps are increasingly widely applied in the field of vehicles, and are not only used for heat management of engines, heat management of battery devices, heat management of driving motors, etc., but also can be used for heat management of vehicle-mounted air conditioners to realize functions of engine temperature regulation, battery temperature regulation, driving motor temperature regulation, passenger cabin temperature regulation, etc.

[0043] The temperature regulation pipelines corresponding to different devices or different assemblies can be switched in series, parallel, mixed parallel, etc. through integrated valve systems to realize linkage between engine temperature regulation, battery temperature regulation, driving motor temperature regulation and passenger cabin temperature regulation, such as battery device heating of cooling liquid with higher temperature after engine cooling.

[0044] However, during switching of the connection relationship between multiple temperature regulation pipelines, adverse effects between different temperature regulation pipelines can occur, such as in autumn and winter and under conditions of high air humidity, although the air conditioner is not turned on, cooling liquid for temperature regulation of other devices or assemblies causes slight temperature change of the air outlet of the air conditioner of the passenger cabin, causes fogging of the vehicle window, discomfort and driving danger caused by local high temperature, etc.

[0045] Furthermore, in the prior art, in order to reduce the above safety hazards, a one-way stop function is realized through a series electromagnetic valve, but the structure is complex, the cost is high, and the arrangement is difficult.

[0046] Based on this, the application provides a volute, an integrated valve body is arranged on the volute, a valve core is arranged in the valve body, and under the premise of realizing the one-way stop function of the water pump, the overall structure can be simplified, the cost can be reduced, and the arrangement difficulty can be reduced.

[0047] Hereinafter, the volute 100, the water pump 1000 and the vehicle according to the embodiments of the application will be described with reference to the accompanying drawings. Figures 1-7 The volute 100, the water pump 1000 and the vehicle according to the embodiments of the application will be described with reference to the accompanying drawings.

[0048] As shown in Figure 2 , Figure 3 , Figure 4 and Figure 5 , the application provides a volute 100, which comprises a shell body 10 and a stop valve 20, the shell body 10 is formed with a communication pipe segment 11; the stop valve 20 comprises a valve body 21 and a valve core 22, the valve body 21 is integrated on the communication pipe segment 11, and the valve core 22 is movably arranged in the valve body 21 to open or close the communication pipe segment 11.

[0049] It should be noted that the volute 100 is detachably arranged on the pump body 200, so that the volute 100 of the application can replace the volute of the conventional water pump to upgrade the conventional water pump, so that the conventional water pump can realize the one-way stop function by replacing the volute 100 of the application.

[0050] Specifically, the shell body 10 has a communication pipe section 11 for guiding the medium into or out of the volute 100, and the valve body 21 of the stop valve 20 is integrated on the communication pipe section 11, that is, the valve body 21 can be co-molded with the volute 100, which can reduce the cost, simplify the structure, reduce the assembly difficulty, reduce the space occupation, and can also give the water pump 1000 using the volute 100 of the application a one-way stop function, enrich the function of the water pump 1000, improve the versatility of the water pump 1000, and when the water pump 1000 is applied to the thermal management system of the vehicle, it can improve the temperature regulation effect of the thermal management system, reduce the interference between the sub-cooling flow paths in parallel in the thermal management system, and improve the user experience.

[0051] It can be understood that the application replaces the electromagnetic valve in series with the water pump 1000 in the prior art by integrating the stop valve 20 to realize the one-way stop function, which can simplify the structure, especially improve the complexity of the pipeline, and reduce the assembly difficulty and cost.

[0052] According to the volute 100 of the application, the valve body 21 is integrated on the communication pipe section 11, so that the stop valve 20 can be integrated on the volute 100, which can simplify the structure of the water pump 1000 using the volute 100 of the application, reduce the difficulty of arranging the stop valve 20, and reduce the production cost of the water pump 1000.

[0053] As shown in Figure 2 and Figure 3 According to some embodiments of the application, the communication pipe section 11 includes an inlet pipe section 11a in the axial direction of the volute 100 and an outlet pipe section 11b in the radial direction of the volute 100, and the valve body 21 is integrated on the inlet pipe section 11a and / or the outlet pipe section 11b.

[0054] In some embodiments, the valve body 21 is integrated on the inlet pipe section 11a to realize one-way stop on the inlet side, in other embodiments, the valve body 21 is integrated on the outlet pipe section 11b to realize one-way stop on the outlet side, and of course, the valve body 21 can be integrated on the inlet pipe section 11a and the outlet pipe section 11b at the same time.

[0055] Therefore, according to the arrangement requirements of the water pump 1000, the volute 100 with one-way stop on the inlet side can be set, or the volute 100 with one-way stop on the outlet side can be set, or the volute 100 with one-way stop on both the inlet side and the outlet side can be set, so that the water pump 1000 using the volute 100 of the application has better use effect and improves the user experience.

[0056] Combination Figure 4 and Figure 5 As shown, according to some embodiments of this application, the valve body 21 includes a cover plate 211 and a body portion 212, the body portion 212 being integrated with the connecting pipe section 11, and the cover plate 211 covering the body portion 212.

[0057] Specifically, the cover plate 211 may include a flange located on the peripheral edge, the flange extending into the valve body 21, and the flange being adapted to push against the body portion 212 to realize the assembly and fixation of the cover plate 211 on the body portion 212. The cover plate 211 and the body portion 212 may be made of the same material, and the two may be assembled by friction welding, hot melt welding, or other methods to improve the sealing effect. The cover plate 211 may also be detachably set on the body portion 212 to facilitate the maintenance and repair of the valve core 22. A receiving space may be defined between the cover plate 211 and the body portion 212, and the valve core 22 is set inside the receiving space.

[0058] This simplifies the structure, reduces the assembly difficulty of the valve core 22 inside the volute 100, and makes the volute 100 more stable and reliable after assembly.

[0059] like Figure 3 , Figure 4 , Figure 6 as well as Figure 7 As shown, according to some embodiments of this application, the connecting pipe section 11 includes: a first section 111 and a second section 112 arranged sequentially in the medium flow direction, and the body part 212 is located between the first section 111 and the second section 112.

[0060] In other words, the first section 111 is located upstream of the second section 112, while the main body 212 is located between the first section 111 and the second section 112, so that the valve core 22 can be opened under the pressure of the medium that flows through the first section 111 first and then through the second section 112. When the water pump 1000 is in the closed state, the external medium acts in the opposite direction to the valve core 22, which can improve the sealing effect of the valve core 22 and the first section 111.

[0061] In this way, by setting the main body 212 between the first segment 111 and the second segment 112, the setting position of the main body 212 is more reasonable. The main body 212 can be located in a relatively smooth area of ​​the inlet pipe segment 11a or in a relatively smooth area of ​​the outlet pipe segment 11b, which can reduce the difficulty of setting the valve core 22 and improve the working stability and reliability of the shut-off valve 20.

[0062] like Figure 6 and Figure 7As shown, according to some embodiments of the present application, the valve core 22 comprises a sealing member 221 and a reset member 222, one end of the reset member 222 abutting against the valve body 21, and the other end of the reset member 222 abutting against the sealing member 221, so as to push the sealing member 221 against the inner wall of the communicating pipe section 11.

[0063] Specifically, the reset member 222 can be configured as a spring, and the sealing member 221 can be configured as a rubber member, when the water pump 1000 is in the closed state, the elastic force of the spring pushes the sealing member 221 against the inner wall of the communicating pipe section, so as to close the communicating pipe section 11, and when the internal medium flows, the medium pressure acts on the sealing member 221 and pushes the sealing member 221 to overcome the elastic force of the spring, at this time the medium can flow to the second section 112 through the gap between the sealing member 221 and the body part 212 and the cover plate 211, so as to realize the conduction of the communicating pipe section 11.

[0064] Thus, by the arrangement of the sealing member 221 and the reset member 222, the one-way cut-off function of the volute 100 can be realized by a relatively simple structure, and the structure of the volute 100 can be further simplified, so as to reduce the production cost of the volute 100.

[0065] It should be noted that in the embodiment in which the reset member 222 is configured as a spring, the wire diameter, effective number of turns and length of the spring, the material and size of the sealing member 221, etc. can be adjusted to adapt to water pumps 1000 of different powers.

[0066] In combination Figure 6 and Figure 7 As shown, according to some embodiments of the present application, the inner diameter of the valve body 21 is greater than the inner diameter of the communicating pipe section 11, so as to define a first step part a and a second step part b between the communicating pipe section 11 and the valve body 21, the reset member 222 abutting against the first step part a, and the sealing member 221 sealingly cooperating with the second step part b.

[0067] Specifically, the inner diameter of the valve body 21 is greater than the inner diameter of the communicating pipe section 11, so that the part of the valve body 21 larger than the inner diameter of the communicating pipe section 11 forms a flow gap, when the valve core 22 is opened, the medium can flow to the second section 112 through the flow gap, and at the same time, the inner diameter of the valve body 21 being greater than the inner diameter of the communicating pipe section 11 can make the end face of the second section 112 adjacent to the body part 212 form the first step part a, and the end face of the first section 111 adjacent to the body part 212 form the second step part b, the first step part a is used for abutting and fixing the reset member 222, and the second step part b can sealingly cooperate with the sealing member 221, so as to realize the plugging of the communicating pipe section 11.

[0068] In this way, the fixing stability and reliability of the reset member 222 can be improved, and the movement of the reset member 222 can be reduced, thereby improving the stability and reliability of the shut-off valve 20.

[0069] It should be noted that at least a portion of the second step b can be constructed as a conical or arc-shaped surface to improve the sealing fit between the seal 221 and the second step b.

[0070] Combination Figure 4 and Figure 5 As shown, according to some embodiments of this application, a guide portion c is provided in the cover plate 211 and / or the body portion 212, and the sealing member 221 is movably disposed in the guide portion c.

[0071] For example, the body portion 212 may be provided with such Figure 4 The guide portion c in the groove shape shown is provided, and the cover plate 211 can be configured as follows: Figure 5 The guide portion c of the rib shown serves to guide the movement of the seal 221, allowing it to move according to the stroke defined by the guide portion c. This improves the smoothness and reliability of the seal 221's movement, while also reducing any lateral movement during its motion and preventing jamming. This ensures that the seal 221 can rebound smoothly, further enhancing the reliability and stability of the shut-off valve 20.

[0072] According to some embodiments of this application, the seal 221 is constructed of a rubber material.

[0073] In this way, the rubber elasticity of the rubber material can better seal the connecting pipe section 11, further improving the sealing effect and sealing reliability.

[0074] For example, if the shut-off valve 20 is installed in the inlet pipe section 11a, when the medium enters the volute 100, the pressure of the entering medium overcomes the elastic force of the reset member 222. When the water pump 1000 is turned off, the seal 221 can be reset to the closed state under the action of the elastic force of the reset member 222 to block the connecting pipe section 11. At this time, the external medium cannot enter the volute 100 through the first section 111. Similarly, in the embodiment where the shut-off valve 20 is installed in the outlet pipe section 11b, when the medium flows out of the volute 100, the pressure of the flow medium overcomes the elastic force of the reset member 222. When the water pump 1000 is turned off, the seal 221 can be reset to the closed state under the action of the elastic force of the reset member 222 to block the connecting pipe section 11. At this time, the outflowing medium cannot flow out through the connecting pipe section 11.

[0075] like Figure 1 As shown, this application provides a water pump 1000, including: a pump body 200 and a volute 100, the volute 100 being detachably disposed on the pump body 200.

[0076] Specifically, the water pump 1000 of the embodiment of the present application adopts the volute 100 described above, so that the water pump 1000 can integrate the one-way stop function, which not only can enrich the use function of the water pump 1000 and improve the use experience, but also can reduce the integration cost of the stop valve 20.

[0077] It can be understood that the volute 100 of the embodiment of the present application can be interchanged with the volute of the existing water pump 1000, so that the existing water pump 1000 has the technical effect of the volute 100 of the embodiment of the present application, and improves the universality of the water pump 1000 of the embodiment of the present application.

[0078] In summary, according to the water pump 1000 of the embodiment of the present application, the stop valve 20 can be at least partially integrated on the volute 100, so that the stop valve 20 structure is integrated on one side of the liquid inlet or one side of the liquid outlet of the volute 100, the one-way stop function of the water pump 1000 is realized, and the structure can be simplified and the cost can be reduced under the premise of improving the use experience.

[0079] The present application provides a vehicle, comprising the water pump 1000 in the above-mentioned embodiments.

[0080] Specifically, the vehicle has a thermal management system, and the water pump 1000 is used in the thermal management system to drive the cooling liquid to flow in the cooling liquid flow path, and the cooling liquid flow path can include a plurality of sub-cooling flow paths, each of which is used for cooling one or more devices or assemblies. By the one-way stop function of the water pump 1000, interference between sub-cooling flow paths in a parallel state can be avoided, such as avoiding the presence of a small amount of water vapor and temperature changes at the passenger compartment air outlet, to improve the use experience and improve the safety and reliability of the thermal management system, thereby improving the ride comfort of the vehicle and further improving the safety and stability of the vehicle.

[0081] The volute 100, the water pump 1000 and the other configurations and operations of the vehicle according to the embodiments of the present application are known to those skilled in the art, and will not be described here.
