[0002] In related technologies, when the port and the connecting hole of a multi-way valve are connected to each other, the sealing effect between them is poor, which can easily lead to liquid leakage. Liquid leakage can cause the performance of the thermal management system to deteriorate, prevent the components from being cooled or heated in a timely and sufficient manner, and easily cause damage to the components, thereby increasing maintenance costs and usage risks. Utility Model Content

[0003] This application provides a multi-way valve, a thermal management system, and a vehicle, which aim to improve the sealing performance when the pipe port and the connecting hole are connected, effectively avoid the problem of liquid leakage, and facilitate the disassembly of the connecting mechanism and the housing for easy maintenance or replacement.

[0004] A multi-way valve according to an embodiment of this application includes: a housing having a plurality of connecting holes; a connecting mechanism rotatably disposed within the housing and including a connecting pipe having a connecting flow channel and a plurality of ports communicating with the connecting flow channel; a sealing assembly including a first driving mechanism and a plurality of sealing slip rings, the plurality of sealing slip rings being respectively sleeved on the outer peripheral walls of the plurality of ports, the sealing slip rings being movable on the connecting pipe, the first driving mechanism being used to drive the sealing slip rings to move toward or away from the connecting holes; and a second driving mechanism disposed on the housing and used to drive the connecting mechanism to rotate in the circumferential direction of the housing, wherein, when the connecting mechanism rotates to make the plurality of ports and the plurality of connecting holes face each other, the first driving mechanism drives the sealing slip rings to move toward the connecting holes and a portion of the sealing slip rings is adapted to extend into the connecting holes.

[0005] According to the embodiments of this application, the multi-way valve has multiple sealing slip rings respectively sleeved on the outer peripheral walls of multiple pipe ports. The sealing slip rings are movable on the connecting pipe. The first driving mechanism can drive the sealing slip rings to move towards or away from the connecting hole. When the connecting mechanism rotates so that the multiple pipe ports and the multiple connecting holes are opposite each other, the first driving mechanism drives the sealing slip rings to move towards the connecting hole, and part of the sealing slip rings are adapted to extend into the connecting hole.

The connecting member is located between the first fixing member and the second fixing member. The magnet rod passes through the second fixing member, and the electromagnet module is located radially inside the second fixing member. The second fixing member provides support for the magnet rod, facilitating guidance. The connecting member's location between the first and second fixing members, and the electromagnet module's radially inside the second fixing member, ensures a compact structure and utilizes the space between the first and second fixing members, thus reducing space requirements.

[0010] According to some embodiments of this application, the fixing component further includes: a guide post, the guide post being at least disposed on one side of the magnet rod along the circumferential direction of the fixing component, the guide post being located between the first fixing member and the second fixing member, and its two ends in the length direction being respectively connected to the first fixing member and the second fixing member, and the connecting member being movably sleeved on the guide post. The guide post improves the structural strength of the fixing component, and the movable sleeve of the connecting member on the guide post limits the movement of the connecting member, further ensuring reliable movement of the connecting member, thereby ensuring reliable movement of the sealing slip ring.

[0011] According to some embodiments of this application, the second driving mechanism further includes: a rotating member located within the housing; and a motor mounted on the housing and connected to the rotating member, the motor driving the rotating member to rotate the connecting pipe along the circumferential direction of the housing. This achieves the rotation requirement of the connecting pipe, facilitating control, and the second driving mechanism has a simple structure, reducing production costs.

[0012] According to some embodiments of this application, the connecting pipe includes multiple connecting sub-pipes, which are spaced apart along the circumferential direction of the housing. Each connecting sub-pipe has a connecting flow channel, and its two ends in the length direction form the pipe openings. The rotating member is used to drive the multiple connecting sub-pipes to rotate along the circumferential direction of the housing. This fulfills the rotation requirement of the connecting pipe, allowing multiple pipe openings to be selectively connected to different connecting holes.

[0013] According to some embodiments of this application, the rotating component includes: a rotating shaft connected to the motor; and multiple rotating plates connected to the outer peripheral wall of the rotating shaft and spaced apart along the circumferential direction of the housing. A connecting sub-tube is provided between adjacent rotating plates, and the rotating plates abut against the connecting sub-tube. This allows the rotating shaft to drive the multiple rotating plates to rotate around the central axis of the rotating shaft. By abutting against the connecting sub-tube, the rotating plates can push the connecting sub-tube to rotate along the circumferential direction of the housing, satisfying the rotational requirements of the connecting sub-tube. Furthermore, the rotating component has a simple structure, is easy to manufacture, and helps reduce production costs.

[0014] According to some embodiments of this application, the end face of the rotating plate facing the connecting sub-tube has a protrusion, which fits against the outer peripheral wall of the connecting sub-tube. The protrusion improves the structural strength of the rotating component, reduces deformation, and the fit between the protrusion and the outer peripheral wall of the connecting sub-tube increases the contact area between the connecting sub-tube and the rotating component, ensuring more reliable rotation of the driving connecting sub-tube and improving the rotation accuracy of the driving connecting sub-tube.

[0015] According to some embodiments of this application, the multi-way valve further includes: an indicator disc located on the side of the housing away from the motor along the axial direction of the housing; the end of the rotating shaft away from the motor extends out of the housing to connect with the indicator disc; and an indicator rib is provided on the end face of the indicator disc away from the housing, opposite to the connecting sub-pipe. While driving multiple rotating plates to rotate, the rotating shaft can also drive the indicator disc to rotate. The indicator rib allows for a direct visual display of the rotation angle and current connection status of the connecting pipe from the outside of the multi-way valve, facilitating the determination of the connection of multiple external pipes, making observation more convenient, and facilitating the adjustment or inspection of the connection relationship.

[0016] According to some embodiments of this application, the multi-way valve is the multi-way valve described in this application, the motor is located on the side of the electromagnet module away from the communication mechanism, and the rotating shaft passes through the electromagnet module. This ensures a compact structure, reduces the space occupied by the multi-way valve, and facilitates the miniaturization design of the multi-way valve.

[0017] According to some embodiments of this application, a fixing ring extending circumferentially along the rotating shaft is provided on the outer peripheral wall of the rotating shaft, and the inner peripheral wall of the electromagnet module is interference-fitted with the outer peripheral wall of the fixing ring. This ensures that the electromagnet module can be reliably fixed on the rotating shaft, and that the rotating shaft can simultaneously drive the electromagnet module to rotate, thus guaranteeing the rotational accuracy of the electromagnet module and ensuring reliable driving of the magnet rod by the electromagnet module.

[0018] According to some embodiments of this application, a clearance groove is provided at the end of the rotating shaft near the motor, and the wire of the first drive mechanism passes through the clearance groove. The clearance groove facilitates the placement of the wire of the first drive mechanism, allowing the wire to extend to the outside along the clearance groove to meet the connection requirements between the wire and the outside. It also utilizes the internal space of the rotating shaft, which helps to reduce the space occupied by the wire when placed outside, thereby facilitating the miniaturization design of the multi-way valve.

[0019] According to some embodiments of this application, a sealing element is provided within the wall of the connecting hole. The sealing element is formed in an annular shape. When a portion of the sealing slip ring extends into the connecting hole, the end face of the sealing slip ring away from the connecting pipe abuts against the end face of the sealing element facing the connecting pipe. This enhances the sealing effect of the sealing slip ring at the connecting hole, ensuring a reliable seal between the connecting hole and the pipe opening, and effectively preventing liquid leakage.

[0020] According to some embodiments of this application, the housing includes: a valve body, the valve body being annular in shape and having a plurality of communicating holes on its outer peripheral wall, the communicating mechanism being located within the valve body; a first valve cover and a second valve cover, the first valve cover and the second valve cover respectively covering both ends of the valve body in the axial direction. This design facilitates placing the communicating mechanism within the housing, protecting the communicating mechanism from exposure and potential damage. Furthermore, the housing has a simple structure, is easy to manufacture, and helps reduce production costs.

[0043] To make the technical problems, technical solutions, and beneficial effects solved by this application clearer, the following detailed description is provided in conjunction with embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this application.

[0044] This application provides a multi-way valve 100, which includes a housing 10, a communication mechanism 20, and a second drive mechanism 50.

[0045] Specifically, such as Figures 1-4 As shown, the housing 10 is provided with multiple connecting holes 11. The connecting mechanism 20 is rotatably disposed within the housing 10. The connecting mechanism 20 includes a connecting pipe 21, which has a connecting flow channel 213 and multiple pipe ports 211. The multiple pipe ports 211 are connected to the connecting flow channel 213. The second driving mechanism 50 is disposed on the housing 10. The second driving mechanism 50 can drive the connecting mechanism 20 to rotate in the circumferential direction of the housing 10, so that the multiple pipe ports 211 can selectively connect to different connecting holes 11. Thus, the multiple pipe ports 211 can connect to different external pipes through multiple different connecting holes 11 to achieve different connection requirements. The multi-way valve 100 has a flexible channel switching function, which can quickly and accurately adjust the connecting mechanism 20 according to thermal management requirements. For example, it can realize channel connection switching for cooling, heating and special working conditions, which can meet complex and diverse thermal management requirements. At the same time, it can reduce the bending and branching of external pipes, making the structure compact and reducing the space occupied by the thermal management system.

[0046] In related technologies, when the pipe opening and the connecting hole are connected to each other, the sealing effect between them is poor, which easily leads to the problem of liquid (such as coolant) leakage. Liquid leakage will cause the performance of the thermal management system to degrade, making it impossible for various components to be cooled or heated in a timely and sufficient manner, which can easily cause damage to various components, increase maintenance costs and usage risks.

[0047] Therefore, in this application, as Figures 3-8 As shown, the multi-way valve 100 also includes a sealing assembly 30, which includes a first driving mechanism 32 and multiple sealing slip rings 31. The multiple sealing slip rings 31 are respectively sleeved on the outer peripheral wall of multiple pipe ports 211. The sealing slip rings 31 are movable on the connecting pipe 21. The first driving mechanism 32 can drive the sealing slip rings 31 to move towards or away from the connecting hole 11 to realize the movement requirements of the sealing slip rings 31.

[0048] Therefore, when the connecting mechanism 20 rotates to align the multiple pipe ports 211 and multiple connecting holes 11, the first driving mechanism 32 drives the sealing slip ring 31 to move towards the connecting hole 11, and part of the sealing slip ring 31 can extend into the connecting hole 11. This ensures the sealing performance when the pipe ports 211 are connected to the connecting holes 11, providing a good sealing effect, effectively preventing liquid leakage, ensuring stable operation of the thermal management system, and reducing maintenance costs and usage risks. Simultaneously, when the first driving mechanism 32 drives the sealing slip ring 31 to move away from the connecting hole 11, the sealing slip ring 31 can extend out of the connecting hole 11, facilitating the disassembly of the connecting mechanism 20 from the housing 10, enabling the rotation of the connecting mechanism 20, and facilitating maintenance or replacement.

[0049] In the embodiments of this application, the number of connecting holes 11 can be flexibly set according to actual conditions. For example, the connecting holes 11 can be as follows: Figure 4 The number shown is six, but it can also be two, three, four, five, seven or more, all of which are within the scope of protection of this application.

[0050] In some embodiments, the number of ports 211 and connecting holes 11 may be the same or different, and can be set according to actual conditions to meet different usage requirements of the multi-way valve 100.

[0051] In some embodiments, the sealing slip ring 31 is made of polytetrafluoroethylene, which gives the sealing slip ring 31 good sealing performance and wear resistance, ensures sealing reliability, extends service life, and effectively reduces the risk of liquid leakage.

[0052] According to the embodiments of this application, the multi-way valve 100 has multiple sealing slip rings 31 respectively sleeved on the outer peripheral walls of multiple pipe ports 211. The sealing slip rings 31 are movable on the connecting pipe 21. The first driving mechanism 32 can drive the sealing slip rings 31 to move towards or away from the connecting hole 11. When the connecting mechanism 20 rotates so that the multiple pipe ports 211 and the multiple connecting holes 11 are opposite each other, the first driving mechanism 32 drives the sealing slip rings 31 to move towards the connecting hole 11 and part of the sealing slip rings 31 is adapted to extend into the connecting hole 11. While enabling the multiple pipe ports 211 to selectively connect with different connecting holes 11 to achieve different communication needs, it ensures the sealing performance when the pipe ports 211 are connected to the connecting holes 11, has a good sealing effect, effectively avoids liquid leakage problems, ensures the stable operation of the thermal management system, can reduce maintenance costs and usage risks, and facilitates the disassembly of the connecting mechanism 20 and the housing 10 for convenient maintenance or replacement.

[0053] According to some embodiments of this application, such as Figure 3 , Figure 6 and Figure 8As shown, the first driving mechanism 32 includes a connector 321, a magnetic rod 322, and an electromagnet module 323. The connector 321 is connected to the outer peripheral wall of the sealing slip ring 31, and the magnetic rod 322 is connected to the connector 321. The electromagnet module 323 is located inside the housing 10. The housing 10 can protect the electromagnet module 323, preventing it from being exposed and damaged. The electromagnet module 323 can drive the magnetic rod 322 to move towards or away from the connecting hole 11. The electromagnet module 323 can continuously maintain the driving force on the magnetic rod 322, ensuring that the sealing slip ring 31 is reliably inserted into the connecting hole 11. This prevents the sealing slip ring 31 from moving within the connecting hole 11 when the multi-way valve 100 is working, thereby ensuring a reliable seal between the pipe port 211 and the connecting hole 11. Furthermore, the first driving mechanism 32 has a simple structure, which can reduce production costs.

[0054] For example, when current is supplied to the electromagnet module 323 in one direction, the magnet rod 322 is driven to move toward the direction closer to the connecting hole 11 by the magnetism of the electromagnet module 323, thus fulfilling the movement requirement of the sealing slip ring 31; when current is supplied to the electromagnet module 323 in another direction, the magnet rod 322 is driven to move away from the connecting hole 11 by the magnetism of the electromagnet module 323, thus fulfilling the movement requirement of the sealing slip ring 31.

[0055] In some embodiments, the connector 321 is an engineering plastic part, which makes the connector 321 have good structural strength and light weight, making it easy to meet the requirements of lightweighting and reduce production costs.

[0056] In some embodiments, the magnet rod 322 is a neodymium iron boron magnet, which makes the magnet rod 322 strong, facilitates the electromagnet module 323 to drive the magnet rod 322, ensures drive reliability, and helps to improve stability.

[0057] In some embodiments of this application, such as Figure 3 , Figures 5-7 As shown, the first drive mechanism 32 also includes a fixing component 324, which is located inside the housing 10 and is formed as a ring extending in the circumferential direction of the housing 10. The electromagnet module 323 is located radially inside the fixing component 324, and the magnet rod 322 passes through the fixing component 324 in the radial direction. The fixing component 324 can guide the movement of the magnet rod 322, ensuring that the magnet rod 322 moves in the radial direction of the fixing component 324, avoiding the displacement of the sealing slip ring 31, ensuring sealing reliability, and ensuring that the structure of the first drive mechanism 32 is compact, thus reducing the space occupied.

[0058] According to some embodiments of this application, such as Figure 3 , Figures 5-7 As shown, the fixing assembly 324 includes a first fixing member 41 and a second fixing member 42. Both the first fixing member 41 and the second fixing member 42 are formed as annular rings extending in the circumferential direction of the housing 10. The second fixing member 42 is located inside the annular ring of the first fixing member 41, and the second fixing member 42 is spaced apart from the first fixing member 41. The fixing assembly 324 has a simple structure and is easy to manufacture. The magnet rod 322 passes through the second fixing member 42, which can support the magnet rod 322 and facilitate guidance. The connecting member 321 is located between the first fixing member 41 and the second fixing member 42, and the electromagnet module 323 is located radially inside the second fixing member 42, ensuring a compact structure and utilizing the space between the first fixing member 41 and the second fixing member 42, which helps to reduce the space occupied.

[0059] In some embodiments, such as Figure 9 As shown, the second fixing member 42 is provided with a guide hole 421, through which the magnet rod 322 passes. The guide hole 421 can support and guide the magnet rod 322. The structure is simple and easy to process and manufacture, which helps to reduce production costs.

[0060] In some embodiments, at least one of the first fixing member 41 and the second fixing member 42 is a copper alloy part, that is, the first fixing member 41 is a copper alloy part, or the second fixing member 42 is a copper alloy part, or both the first fixing member 41 and the second fixing member 42 are copper alloy parts. Copper alloy parts have good corrosion resistance, which is beneficial to extending service life, and are easy to process and manufacture, which is beneficial to reducing production costs.

[0061] In some embodiments of this application, such as Figure 6 and Figure 9 As shown, the fixing assembly 324 also includes a guide post 43. The guide post 43 is at least located on one side of the magnet rod 322 along the circumferential direction of the fixing assembly 324. The guide post 43 is located between the first fixing member 41 and the second fixing member 42, and the two ends of the guide post 43 in the length direction are respectively connected to the first fixing member 41 and the second fixing member 42, so that the first fixing member 41 and the second fixing member 42 can be connected through the guide post 43, ensuring the relative position of the first fixing member 41 and the second fixing member 42, facilitating the assembly of the fixing assembly 324, and improving the structural strength of the fixing assembly 324 through the guide post 43. The connecting member 321 is movably sleeved on the guide post 43, and the guide post 43 can limit the movement of the connecting member 321, further ensuring the reliable movement of the connecting member 321, thereby ensuring the reliable movement of the sealing slip ring 31.

[0062] In some embodiments, the guide post 43 is made of stainless steel to ensure high structural strength and avoid problems such as deformation. The outer surface of the guide post 43 is polished to ensure low frictional resistance, ensuring smooth sliding of the connector 321 on the guide post 43, thereby ensuring reliable movement of the sealing slip ring 31.

[0063] In some embodiments, such as Figure 8 As shown, the connector 321 is provided with a mating hole 325. The mating hole 325 is provided on at least one side of the magnet rod 322 along the length direction of the connector 321. The guide post 43 is slidably inserted into the mating hole 325, which enables the connector 321 to be sleeved on the guide post 43. The connector 321 has a simple structure, is easy to process and manufacture, and helps to reduce production costs.

[0064] In some embodiments of this application, such as Figure 3 , Figure 4 , Figure 6 and Figure 10 As shown, the second drive mechanism 50 includes a rotating component 22 and a motor 51. The rotating component 22 is located inside the housing 10, and the motor 51 is mounted on the housing 10 and connected to the rotating component 22. When the motor 51 is working, it can drive the rotating component 22 to push the connecting pipe 21 to rotate in the circumferential direction of the housing 10, thereby fulfilling the rotation requirement of the connecting pipe 21. This makes control convenient, and the structure of the second drive mechanism 50 is simple, which can reduce production costs.

[0065] According to some embodiments of this application, such as Figure 3 , Figure 4 , Figure 6 and Figure 8 As shown, the connecting pipe 21 includes multiple connecting sub-pipes 212, which are spaced apart along the circumferential direction of the housing 10. Each connecting sub-pipe 212 has a connecting flow channel 213, and both ends of the connecting sub-pipe 212 are formed as openings 211 along its length. This allows the two required connecting holes 11 to be achieved through one connecting sub-pipe 212. The connecting pipe 21 has a simple structure, is easy to process, manufacture, and assemble, and helps reduce production costs. The rotating component 22 can drive the multiple connecting sub-pipes 212 to rotate along the circumferential direction of the housing 10, thus fulfilling the rotation requirement of the connecting pipe 21 and allowing the multiple openings 211 to selectively connect with different connecting holes 11. For example, the connecting sub-pipes 212 can be made of copper pipes, which simplifies the structure, facilitates the processing and manufacturing of the connecting sub-pipes 212, and reduces production costs.

[0066] In the embodiments of this application, the number of connecting sub-tubes 212 can be flexibly set according to actual conditions. For example, the connecting sub-tubes 212 can be as follows: Figure 4The number shown is three, but it can also be two, four, five, six or more, all of which are within the scope of protection of this application.

[0067] In some embodiments of this application, such as Figure 3 , Figure 4 , Figure 6 and Figure 10 As shown, the rotating component 22 includes a rotating shaft 221 and multiple rotating plates 222. The rotating shaft 221 is connected to the motor 51, and the multiple rotating plates 222 are connected to the outer peripheral wall of the rotating shaft 221. The multiple rotating plates 222 are spaced apart along the circumferential direction of the housing 10, and a connecting tube 212 is provided between two adjacent rotating plates 222. The rotating plates 222 abut against the connecting tube 212. Thus, when the motor 51 is working, the motor 51 can drive the rotating shaft 221 to rotate, so that the rotating shaft 221 can drive the multiple rotating plates 222 to rotate around the central axis of the rotating shaft 221. Through the abutment of the multiple rotating plates 222 against the connecting tube 212, the rotating plates 222 can push the connecting tube 212 to rotate along the circumferential direction of the housing 10, satisfying the rotation requirements of the connecting tube 212. Moreover, the rotating component 22 has a simple structure, is easy to process and manufacture, and helps to reduce production costs.

[0068] According to some embodiments of this application, such as Figure 4 and Figure 10 As shown, the end face of the rotating plate 222 facing the connecting sub-tube 212 is provided with a protrusion 223. The protrusion 223 can improve the structural strength of the rotating component 22 and reduce deformation and other problems. The protrusion 223 fits against the outer peripheral wall of the connecting sub-tube 212, which can increase the contact area between the connecting sub-tube 212 and the rotating component 22, ensuring that the rotation of the driving connecting sub-tube is more reliable and improving the rotation accuracy of the driving connecting sub-tube.

[0069] In some embodiments of this application, such as Figure 2 As shown, the multi-way valve 100 also includes an indicator disc 60, which is located on the side of the housing 10 away from the motor 51 along the axial direction of the housing 10 (e.g., Figure 3 (As shown in the lower side), the end of the rotating shaft 221 away from the motor 51 extends out of the housing 10 to connect with the indicator disk 60. The end face of the indicator disk 60 away from the housing 10 is provided with an indicator rib 61, which is arranged opposite to the connecting sub-tube 212.

[0070] Therefore, when the motor 51 drives the rotating shaft 221 to rotate, the rotating shaft 221 can drive the indicator disc 60 to rotate while driving multiple rotating plates 222 to rotate. The indicator rib 61 can intuitively display the rotation angle and current connection status of the connecting pipe 21 from the outside of the multi-way valve 100, which is convenient for determining the connection of multiple external pipes, making observation more convenient, and facilitating the adjustment or inspection of the connection relationship.

[0071] It should be noted that, for ease of description, the terms "up" and "down" in this application are based on the orientation relationships shown in the accompanying drawings, and are not intended to limit the orientation in actual application.

[0072] In some embodiments, the indicator disc 60 is made of plastic, which facilitates the processing and manufacturing of the indicator disc 60, makes it easier to form the indicator rib 61, and reduces the weight of the indicator disc 60, thus facilitating the lightweight design of the multi-way valve 100.

[0073] In some embodiments of the first drive mechanism 32, which includes a connector 321, a magnetic rod 322, and an electromagnet module 323, such as Figure 3 As shown, the motor 51 is located on the side of the electromagnet module 323 away from the communication mechanism 20 (e.g., Figure 3 As shown on the upper side), the rotating shaft 221 passes through the electromagnet module 323, ensuring a compact structure, reducing the space occupied by the multi-way valve 100, and facilitating the miniaturization design of the multi-way valve 100.

[0074] In some embodiments where the first drive mechanism 32 also includes a fixing component 324, such as Figure 6 and Figure 7 As shown, a rotating ring 44 is provided between the outer peripheral wall of the fixing component 324 and the inner peripheral wall of the housing 10. The rotating ring 44 is made of aluminum alloy. When the fixing component 324 rotates, the rotating ring 44 of the aluminum alloy can reduce the friction between the fixing component 324 and the housing 10, avoid wear and other problems, and help extend the service life.

[0075] In some embodiments, such as Figure 6 and Figure 9 As shown, the fixing component 324 is provided with a connecting part 411. The connecting part 411 extends toward the side close to the rotating plate 222 and is connected to the rotating plate 222, which can realize the connection between the rotating component 22 and the fixing component 324. When the motor 51 drives the rotating component 22 to push the connecting pipe 21 to rotate in the circumferential direction of the housing 10, the rotating component 22 can simultaneously drive the fixing component 324 to rotate synchronously, ensuring that the moving of the fixing component 324 is reliable, thereby ensuring the accurate position of the sealing slip ring 31 and ensuring reliable sealing.

[0076] In some embodiments, there are multiple (two or more) connecting parts 411, which are spaced apart along the circumferential direction of the fixing component 324. The multiple connecting parts 411 can be connected to multiple rotating plates 222 respectively, so as to realize the connection between multiple different positions of the fixing component 324 and the rotating member 22, ensuring that the connection of the fixing component 324 is reliable and avoiding problems such as stress concentration, and ensuring uniform force distribution.

[0077] In some embodiments, the connecting part 411 and the rotating plate 222 are connected by a fastener 104, which ensures a reliable connection between the connecting part 411 and the rotating plate 222 and facilitates assembly and disassembly, thereby improving assembly efficiency. For example, the fastener 104 is a screw or the like.

[0078] For example, in some specific embodiments, the multi-way valve 100 is applied to a thermal management system, which is applied to a vehicle.

[0079] The thermal management system is installed and commissioned. The multi-way valve 100 is installed in the thermal management system's piping, ensuring the connecting hole 11 is correctly connected to other piping in the thermal management system. The motor 51 and electromagnet module 323 are connected to the vehicle's power supply and control systems. The wiring connections are checked for secureness to avoid loose connections or short circuits. The thermal management system's commissioning program is started, sending control signals to the multi-way valve 100. The rotation function of the motor 51 is tested, and the connecting mechanism 20 is observed to ensure normal rotation. With the multi-way valve 100 including the indicator panel 60, the accuracy of the indicator panel 60's indication is checked. Simultaneously, the sealing of each connection 411 is tested. A pressure testing device is used to fill the piping with gas or liquid at a certain pressure to check for leaks. If leaks are found, they are promptly investigated and repaired.

[0080] The thermal management system operates in its initial state. Before the thermal management system starts or when it is in standby mode, the electromagnet module 323 is not energized, and multiple ports 211 are connected to multiple connecting holes 11 respectively, forming a specific small circulation path, such as the battery preheating or precooling circuit of the vehicle. Under the action of the like pole repulsion between the magnet rod 322 and the electromagnet module 323, the sealing slip ring 31 moves towards the direction of the connecting hole 11 and partially extends into the corresponding connection hole, achieving a good sealing effect and preventing coolant leakage.

[0081] The thermal management system operates in cooling mode. When the vehicle is running and needs to cool components such as the battery and motor 51, the thermal management system sends control signals to the motor 51 and electromagnet module 323 based on the temperature data of the battery and motor 51 monitored by the sensors. The electromagnet module 323 is first energized to generate magnetism opposite to its initial state, attracting the magnet rod 322, causing the magnet rod 322 to move the sealing slip ring 31 away from the connecting hole 11, allowing the sealing slip ring 31 to disengage from the connecting hole.

[0082] Then, motor 51 starts, driving rotating shaft 221 to rotate. Rotating shaft 221 drives multiple rotating plates 222 to rotate, enabling multiple rotating plates 222 to push the connecting sub-pipe 212 to rotate. When the rotation reaches the point where the two ports 211 of one of the connecting sub-pipes 212 are respectively connected to the channels of the battery cooling system, motor 51 cooling system and radiator, motor 51 stops working. Electromagnet module 323 is energized again to generate opposite magnetism, pushing magnet rod 322 to drive sealing slip ring 31 to move towards the connecting hole 11 and partially extend into the connecting hole 11, forming a stable sealing connection. Under the action of water pump, coolant flows out from radiator, flows through the cooling channels of battery cooling system and motor 51 cooling system in sequence, absorbs heat and flows back to radiator to dissipate heat, realizing the cooling cycle of thermal management system.

[0083] The thermal management system operates in heating or special working condition modes. In cold weather, when the vehicle's battery or cabin needs heating, or when the battery needs equalization heating, the thermal management system sends corresponding control signals to the motor 51 and the electromagnet module 323. The electromagnet module 323 changes its magnetism according to the control signals, controlling the extension and retraction of the sealing slip ring 31. The motor 51 drives the connecting pipe 21 to rotate to a specific angle through the rotating component 22, connecting the channel between the battery heating device, the cabin heating system, and the engine waste heat recovery system. At this time, the waste heat generated by the engine or the heat generated by the battery heating device is used to provide heat to the battery and cabin, realizing the heating function of the thermal management system or meeting the needs of special working conditions.

[0084] The thermal management system should be maintained and serviced. Regularly check the connecting pipe 21 for deformation or damage to facilitate maintenance or replacement. Inspect the sealing slip ring 31 at regular intervals; if wear or aging is found, replace it promptly to ensure sealing performance. Check the operating status of the motor 51 and the electromagnet module 323, using professional testing equipment to test their electrical performance; repair or replace any faulty components promptly. Clean dust and debris from the surface of the multi-way valve 100 to avoid affecting heat dissipation and normal operation.

[0085] According to some embodiments of this application, such as Figure 3 , Figure 6 and Figure 10 As shown, a fixing ring 224 is provided on the outer peripheral wall of the rotating shaft 221. The fixing ring 224 extends in the circumferential direction of the rotating shaft 221. The inner peripheral wall of the electromagnet module 323 is interference-fitted with the outer peripheral wall of the fixing ring 224, so that the electromagnet module 323 can be reliably fixed on the rotating shaft 221. When the rotating shaft 221 rotates, it can drive the electromagnet module 323 to rotate at the same time, which can ensure the rotation accuracy of the electromagnet module 323, thereby ensuring that the electromagnet module 323 reliably drives the magnet rod 322.

[0086] In some embodiments of this application, such as Figure 3 and Figure 10 As shown, a clearance groove 225 is provided at the end of the rotating shaft 221 near the motor 51. The wire of the first drive mechanism 32 passes through the clearance groove 225. The clearance groove 225 facilitates the placement of the wire of the first drive mechanism 32, allowing the wire to extend to the outside along the clearance groove 225 to meet the connection requirements with the outside. For example, the wire can be used to control the magnetism of the electromagnet module 323 from the outside. Moreover, the internal space of the rotating shaft 221 can be utilized, which helps to reduce the space occupied by the wire when placed outside, thereby facilitating the miniaturization design of the multi-way valve 100. For example, the motor 51 can be a hollow shaft motor 51.

[0087] In some embodiments, such as Figure 6 and Figure 10 As shown, the outer peripheral wall of the rotating shaft 221 is provided with a clearance hole 226, which is connected to the clearance groove 225. The wire can pass through the clearance hole 226 to connect with the first drive mechanism 32, thus realizing the connection requirement between the first drive mechanism 32 and the wire. The structure is simple and easy to process and manufacture.

[0088] According to some embodiments of this application, such as Figure 4 , Figure 5 and Figure 7 As shown, a sealing element 111 is provided inside the wall of the connecting hole 11. The sealing element 111 is formed into a ring. When a portion of the sealing slip ring 31 extends into the connecting hole 11, the end face of the sealing slip ring 31 away from the connecting pipe 21 abuts against the end face of the sealing element 111 facing the connecting pipe 21. This enhances the sealing effect of the sealing slip ring 31 at the connecting hole 11, making the connection hole 11 and the pipe opening 211 reliably sealed and effectively preventing liquid leakage.

[0089] In some embodiments, the seal 111 is a rubber component. The rubber component has high elasticity and wear resistance, which can ensure reliable sealing between the sealing slip ring 31 and the seal 111, and facilitate the processing and manufacturing of the seal 111, thereby reducing production costs.

[0090] In some embodiments, the seal 111 is inspected at regular intervals. If wear or aging is found in the seal 111, it is replaced in time to ensure sealing performance and thus ensure the normal operation of the multi-way valve 100.

[0091] In some embodiments of this application, such as Figure 5As shown, the inner peripheral wall of the seal 111 is flush with the inner peripheral wall of the sealing slip ring 31, ensuring smooth liquid flow, avoiding obstruction of the liquid, and reducing leakage between the seal 111 and the sealing slip ring 31, thereby further improving the sealing reliability.

[0092] According to some embodiments of this application, such as Figure 5 As shown, the thickness of the seal 111 is 2mm-4mm along the radial direction, that is, the thickness of the seal 111 is T along the radial direction and satisfies 2mm≤T≤4mm. Within the above-mentioned size range, the sealing reliability of the seal 111 and the sealing slip ring 31 can be ensured, and it is easy to process and manufacture, with low production cost. For example, in some specific embodiments, the thickness of the seal 111 along the radial direction can be 2mm, 2.5mm, 3mm, 3.5mm, 4mm, etc.

[0093] In some embodiments of this application, such as Figures 1-3 As shown, the housing 10 includes a valve body 101, a first valve cover 102, and a second valve cover 103. The valve body 101 is formed in an annular shape, and a plurality of connecting holes 11 are provided on the outer peripheral wall of the valve body 101. The connecting mechanism 20 is located inside the valve body 101. The first valve cover 102 and the second valve cover 103 are respectively covered on the valve body 101 in the axial direction (e.g., Figure 3 The two ends (in the up and down direction shown in the figure) facilitate the placement of the connecting mechanism 20 inside the housing 10, which can protect the connecting mechanism 20 and prevent it from being exposed and damaged. In addition, the structure of the housing 10 is simple, easy to process and manufacture, and helps to reduce production costs.

[0094] In some embodiments, such as Figures 1-3 As shown, the valve body 101, the first valve cover 102, and the second valve cover 103 are connected by multiple fasteners 104, ensuring reliable connection between the valve body 101, the first valve cover 102, and the second valve cover 103, and facilitating installation and disassembly, which helps reduce production costs and improve assembly efficiency. For example, the fasteners 104 can be bolts, etc.

[0095] In the embodiments of this application, the number of fasteners 104 can be flexibly set according to actual conditions. For example, the fasteners 104 can be as follows: Figure 3 The number shown is six, but it can also be two, three, four, five, seven or more, all of which are within the scope of protection of this application.

[0096] In some embodiments, the appearance of the multi-way valve 100 is inspected periodically to check whether the fasteners 104 connecting the valve body 101, the first valve cover 102, and the second valve cover 103 are loose, and any loose fasteners 104 are tightened to ensure the normal use of the multi-way valve 100 and to achieve maintenance and upkeep of the multi-way valve 100.

[0097] In some embodiments, the valve body 101 can be an aluminum alloy part, which can improve the structural strength of the valve body 101, have good pressure resistance and corrosion resistance, which is beneficial to extend the service life, and is lightweight, making it easy to realize the lightweight design of the valve body 101.

[0098] In some embodiments, the valve body 101 is formed by precision casting, which enables the valve body 101 to be processed into complex shapes, meet the required shape requirements, facilitate processing and manufacturing, and ensure good pressure resistance and corrosion resistance, which is beneficial to extending service life.

[0099] In some embodiments, a sealing ring is provided between the valve body 101 and the first valve cover 102 to achieve a seal between the valve body 101 and the first valve cover 102, ensuring reliable sealing and preventing external dust and other impurities from entering the interior through the gap between the valve body 101 and the first valve cover 102, which could cause damage to the communication mechanism 20, thus extending the service life of the multi-way valve 100. For example, the sealing ring can be a rubber sealing gasket.

[0100] In some embodiments, a sealing ring is provided between the valve body 101 and the second valve cover 103, which can achieve a seal between the valve body 101 and the second valve cover 103, ensuring reliable sealing and preventing external dust and other impurities from entering the interior through the gap between the valve body 101 and the second valve cover 103, which could cause damage to the communication mechanism 20, thus helping to extend the service life of the multi-way valve 100.

[0101] In some embodiments, such as Figures 1-5 As shown, multiple connecting pipes 112 are connected to the outer peripheral wall of the valve body 101. Each connecting pipe 112 corresponds to one of the multiple connecting holes 11. The multiple connecting pipes 112 are arranged around the multiple connecting holes 11 respectively. The connection pipes 112 facilitate the connection between the external pipeline and the multi-way valve 100, ensuring reliable connection.

[0102] In some embodiments, the connecting pipe 112 is welded to the valve body 101 to ensure a reliable connection between the connecting pipe 112 and the valve body 101, which helps to improve the connection strength and sealing performance and avoid problems such as liquid leakage.

[0103] In some embodiments, the connecting pipe 112 is made of stainless steel. Stainless steel has good structural strength and corrosion resistance, which helps to extend its service life and facilitates the connection of the connecting pipe 112 to external pipelines.

[0104] In some embodiments, the connecting pipe 112 and the external pipeline are fixed by pipe clamps or flanges to ensure reliable connection between the connecting pipe 112 and the external pipeline and to avoid problems such as liquid leakage.

[0105] The thermal management system according to an embodiment of this application includes a multi-way valve 100 according to an embodiment of this application. Since the multi-way valve 100 according to an embodiment of this application has the aforementioned beneficial technical effects, the thermal management system according to an embodiment of this application uses multiple sealing slip rings 31 respectively sleeved on the outer peripheral walls of multiple pipe ports 211. The sealing slip rings 31 are movable on the connecting pipe 21. A first driving mechanism 32 can drive the sealing slip rings 31 to move towards or away from the connecting hole 11. When the connecting mechanism 20 rotates to make the multiple pipe ports 211 and the multiple connecting holes 11 face each other, the first driving mechanism 32 drives the sealing slip rings 31 to move towards the connecting hole 11, and part of the sealing slip rings 31 are adapted to extend into the connecting hole 11. This allows the multiple pipe ports 211 to selectively connect with different connecting holes 11 to achieve different communication needs, while ensuring the sealing performance when the pipe ports 211 are connected to the connecting holes 11. This provides a good sealing effect, effectively avoids liquid leakage, ensures stable operation of the thermal management system, reduces maintenance costs and usage risks, and facilitates the disassembly of the connecting mechanism 20 from the housing 10 for convenient maintenance or replacement.

[0106] The vehicle according to the embodiments of this application includes a thermal management system according to the embodiments of this application. Since the thermal management system according to the embodiments of this application has the aforementioned beneficial technical effects, the vehicle according to the embodiments of this application uses multiple sealing slip rings 31 respectively sleeved on the outer peripheral walls of multiple pipe openings 211. The sealing slip rings 31 are movable on the connecting pipe 21. The first driving mechanism 32 can drive the sealing slip rings 31 to move towards or away from the connecting hole 11. When the connecting mechanism 20 rotates so that the multiple pipe openings 211 and the multiple connecting holes 11 are opposite each other, the first driving mechanism 32 drives the sealing slip rings 31 to move towards the connecting hole 11, and part of the sealing slip rings 31 are adapted to extend into the connecting hole 11. This allows the multiple pipe openings 211 to selectively connect with different connecting holes 11 to achieve different communication needs, while ensuring the sealing performance when the pipe openings 211 are connected to the connecting holes 11. This provides a good sealing effect, effectively avoids liquid leakage, ensures stable operation of the thermal management system, reduces maintenance costs and usage risks, and facilitates the disassembly of the connecting mechanism 20 from the housing 10 for convenient maintenance or replacement.

[0107] In some embodiments, the multi-way valve 100 of this application is applied to a thermal management system. A sealing slip ring 31 is fitted onto the outer peripheral wall of each port 211. The sealing slip ring 31 is movable on the connecting pipe 21. When the port 211 and the connecting hole 11 are opposite, the sealing slip ring 31 moves towards or away from the connecting hole 11 and is partially adapted to extend into the connecting hole 11. When the sealing slip ring 31 moves towards the connecting hole 11, it can partially extend into the connecting hole 11, ensuring a tight seal when the port 211 is connected to the connecting hole 11. This provides a good sealing effect, effectively preventing liquid leakage and ensuring the stable operation of the thermal management system. This avoids affecting the overall performance and safety of the vehicle, and further prevents damage to other vehicle components, thus reducing maintenance costs and usage risks, and ultimately improving the overall performance and safety of the vehicle. For example, the vehicle can be a new energy vehicle.
