[0024] In order to make the purpose, technical solutions and advantages of the present application clearer, the present application is further described in detail below in conjunction with the accompanying drawings and specific embodiments. In this article, relational terms such as "first" and "second" are only used to distinguish one component with the same name from another, and do not necessarily require or imply that there is any such actual relationship or order between these components. It should be noted that the "limited connection" in this application includes detachable connections, such as threaded connections, snap connections, etc., and the "fixed connection" in this application includes non-detachable connections, such as welding, bonding, vulcanization fixation, riveting, insert injection molding, etc.

[0025] Figures 1 to 5 An embodiment of a valve device 100 is shown. The valve device 100 includes a valve body assembly 10, a valve core 7, a transmission assembly 9, and a driving unit 8. The driving unit 8 includes a rotor assembly 82 and a stator assembly 81. The valve body assembly 10 has a receiving chamber 31, and at least part of the valve core 7 is located in the receiving chamber 31. The rotor assembly 82 is in transmission connection with the transmission assembly 9, and the valve core 7 is in transmission connection with the transmission assembly 9. The valve core 7 can rotate under the drive of the transmission assembly 9. The stator assembly 81 can be electrically connected and / or signal connected to the outside world. At least part of the stator assembly 81 is located on the periphery of the rotor assembly 82. The transmission assembly 9 is a planetary gear mechanism.

[0026] The axial direction of the valve device 100 is defined, and the axial direction of the valve device 100 is indicated by H in the figure. The rotation axis of the valve core 7 is defined, and the rotation axis of the valve core 7 is indicated by C1 in the figure. The valve core 7 can rotate around the rotation axis. The axial direction of the valve device 100 is the same as the extension direction of the rotation axis of the valve core 7. The central axis of the valve device 100 coincides with the rotation axis of the valve core 7.

[0027] Figure 6-Figure 11 An embodiment of an integrated component is shown, the integrated component includes a connecting component 6 and the aforementioned valve device 100, the valve device 100 is fixedly connected or limitedly connected to the connecting component 6, the connecting component 6 has an installation cavity 63, at least part of the valve body component 10 is located in the installation cavity 63. The connecting component 6 can be plate-shaped or block-shaped, Figure 6 Only a part of the communication component 6 is shown, and other valves, pumps, heat exchangers, sensors, etc. may be integrated in the communication component 6.

[0028] The wall forming the installation cavity 63 includes at least one first side wall 641 and at least one second side wall 643. The valve body assembly 10 includes an outer peripheral portion 32. Along the radial direction of the valve device 100, the second side wall 643 is closer to the outer peripheral portion 32 than the first side wall 641. The first side wall 641 and the second side wall 643 are distributed along the circumference of the valve device 100. The valve device 100 includes a first sealing member 51. The first sealing member 51 includes a first sealing portion 512. Along the radial direction of the valve device 100, at least part of the first sealing portion 512 protrudes from the outer peripheral portion 32. Along the radial direction of the valve device 100, the outer side of the first sealing portion 512 abuts against the second side wall 643, and a gap is set between the first side wall 641 and the outer peripheral portion 32.

[0029] Along the radial direction of the valve device 100, the second side wall 643 is closer to the outer peripheral portion 32 than the first side wall 641, which can reduce the friction between the first seal 51 and the second side wall 643 during the assembly process of the integrated component. Specifically, when the valve body assembly 10 is axially installed into the installation cavity 63, the friction between the first sealing portion 512 and the connecting component 6 during insertion can be reduced, and the adverse deformation of the first sealing portion 512 can be reduced, thereby reducing the risk of a gap between the first sealing portion 512 and the wall forming the installation cavity 63, thereby improving the sealing effect. In addition, the risk of damage or falling off of the first sealing portion 512 during insertion can also be reduced. The "outside" in this application refers to the side of the central axis of the valve device 100 that is relatively far away from the valve device 100.

[0030] Fig.12 , Fig.13 An intermediate state of the integrated component during assembly is shown.

[0031] The assembly method of the integrated component includes at least:

[0032] Step S1, inserting the valve body assembly 10 into the installation cavity 63 along the axial direction of the valve device 100, so that the radial outer side of the first sealing portion 512 is arranged opposite to the first side wall 641;

[0033] Step S2 : rotating the valve device 100 in the circumferential direction so that the radial outer side of the first sealing portion 512 faces and abuts against the second side wall 643 .

[0034] At the end of step S1, the state of the integrated component is as follows Fig.12 , Fig.13 As shown, since the radial outer side of the first sealing portion 512 remains opposite to the first side wall 641 when inserted into the installation cavity 63, the first sealing portion 512 is subjected to less friction compared to the insertion method in which the first sealing portion 512 rubs against the second side wall 643.

[0035] In the present embodiment, when the valve body assembly 10 is inserted into the mounting cavity 63 along the axial direction of the valve device 100, along the radial direction of the valve device 100, the height of the first sealing portion 512 protruding from the outer peripheral portion 32 is less than the distance between the first side wall 641 and the outer peripheral portion 32. At this time, the first sealing portion 512 is in an un-extruded state, so that when the valve device 100 is inserted into the mounting cavity 63, the radial outer side of the first sealing portion 512 does not rub against the first side wall 641, thereby further reducing the adverse deformation of the first sealing portion 512.

[0036] In this embodiment, the first sealing portion 512 substantially extends along the axial direction of the valve device 100, and the second side wall 643 substantially extends along the axial direction of the valve device 100. “Substantially extending along the axial direction of the valve device 100” means that the angle with the axial direction is less than 20°.

[0037] like Figure 7-Figure 11 As shown, in this embodiment, the connecting component 6 includes two convex ribs 66, and the two convex ribs 66 are spaced apart along the circumference of the valve device 100. The convex ribs 66 extend along the axial direction of the valve device 100. Along the radial direction of the valve device 100, the convex ribs 66 protrude from the first side wall 641 to the outer peripheral portion 32, and the second side wall 643 is formed at the top of the convex ribs 66. The convex ribs 66 are used to form the second side wall 643, which has a simple structure, is easy to process and reduce weight. In other embodiments, the number of the convex ribs 66 can be three or more.

[0038] The outer peripheral portion 32 has a first communication port 35, and at least a portion of the first sealing member 51 surrounds the first communication port 35. The first sealing member 51 includes at least two first sealing portions 512. Along the circumference of the valve device 100, the first communication port 35 is located between two adjacent first sealing portions 512. The first sealing member 51 is located between the wall forming the installation cavity 63 and the valve body assembly 10. The wall forming the installation cavity 63 and the valve body assembly 10 press the second sealing member 52 to form a seal, thereby separating the first communication port 35 from other flow paths and reducing internal leakage.

[0039] Specifically, the wall forming the installation cavity 63 includes a third side wall 644. Along the circumference of the valve device 100, the third side wall 644 is located between the second side wall 643 and the first side wall 641. One side of the third side wall 644 is adjacent to the first side wall 641, and the other side of the third side wall 644 is adjacent to the second side wall 643. The angle formed by the third side wall 644 and the second side wall 643 is an obtuse angle. In step S2, the third side wall 644 can play a guiding role, making the valve device 100 easier to rotate and reducing the bumps on the first sealing part 512. The outer side of the first sealing part 512 is also convex, making the valve device 100 easier to rotate and reducing the bumps on the first sealing part 512.

[0040] The outer peripheral portion 32 includes a fourth side wall 321 and a fifth side wall 322. The first side wall 641 is cylindrical, the fourth side wall 321 is cylindrical, the first sealing portion 512 protrudes from the fourth side wall 321, and the first side wall 641 is coaxially arranged with the fourth side wall 321. The fifth side wall 322 is planar, the first communication port 35 is located on the fifth side wall 322, and the planar fifth side wall 322 can reduce the radial dimension of the valve body assembly 10.

[0041] The connecting component 6 includes a mounting surface 68, the mounting cavity 63 has a mounting opening 69 on the mounting surface 68, and the connecting component 6 has a groove 67, and the groove 67 is recessed in the mounting surface 68 along the axial direction of the valve device 100; a first plane is defined, the first plane is perpendicular to the axial direction of the valve device 100, and the projection of the side wall of the groove 67 on the first plane is arc-shaped, and the center of the side wall is substantially coincident with the rotation axis of the valve device 100 in step S2, and the rotation axis of the valve device 100 in step S2 is at Fig.10 As shown in C2, the valve device 100 includes a positioning portion 14, at least part of the positioning portion 14 is located in the groove 67, and the positioning portion 14 is slidably matched with the side wall forming the groove 67. Specifically, during the execution of step S1, at least part of the positioning portion 14 is inserted into the groove 67, so that the positioning portion 14 is located at one end of the groove 67, and the guide portion can play a positioning role at this time, ensuring that the first sealing portion 512 and the second side wall 643 are staggered; during the execution of step S2, the positioning portion 14 rotates with the valve device 100, and the side wall forming the groove 67 plays a guiding role for the positioning portion 14. At the end of step S2, the guide portion is located at the other end of the groove 67, and the guide portion can also play a positioning role at this time, so that the valve device 100 is rotated to the specified position more accurately, thereby ensuring the sealing effect.

[0042] Specifically, the valve body assembly 10 has a mounting plate 13, which is abutted or fixedly connected to the mounting surface portion 68, and extends outward from the outer peripheral portion 32 along the radial direction of the valve device 100; the positioning portion 14 is fixedly connected or limit-connected to the mounting plate 13 or is an integral structure, and a portion of the positioning portion 14 extends from the mounting plate 13 along the axial direction of the valve device 100.

[0043] like Figure 1-Figure 5 As shown, the valve device 100 includes a driving portion 8, and the valve body assembly 10 includes a main body 12, and the peripheral portion 32 is located in the main body 12; the main body 12 includes an end face portion 121, and along the axial direction of the valve device 100, the end face portion 121 is located at an end of the main body 12 away from the driving portion 8, and the end face portion 121 faces away from the driving portion 8. The first sealing member 51 includes a second sealing portion 513, and the second sealing portion 513 is fixedly connected or limitedly connected to the end face portion 121 to define a first plane, and the first plane is perpendicular to the axial direction of the valve device 100. Along the axial direction of the valve device 100, the projection of the second sealing portion 513 on the first plane is located on the inner side of the projection of the main body 12 on the first plane. When executing step S1, the friction between the second sealing portion 513 and the wall forming the installation cavity 63 can be reduced.

[0044] like Figure 7-Figure 11 As shown, the installation cavity 63 includes a first cavity 64, at least a portion of the main body 12 is located in the first cavity 64, and the wall forming the first cavity 64 includes a bottom wall 642. Along the axial direction of the valve device 100, one side of the second sealing portion 513 abuts against the bottom wall 642, and the other side of the second sealing portion 513 abuts against the end surface portion 121, thereby achieving sealing.

[0045] like Figure 1-Figure 5As shown, the valve body assembly 10 includes a first limiting portion 11. Along the axial direction of the valve device 100, the first limiting portion 11 is away from the driving portion 8 relative to the main body 12. Along the axial direction of the valve device 100, the first limiting portion 11 protrudes from the end surface portion 121; the installation cavity 63 includes a second cavity 65, at least part of the first limiting portion 11 is located in the second cavity 65, along the axial direction of the valve device 100, the second cavity 65 extends from the bottom wall 642 to the direction away from the driving portion 8; at least part of the first limiting portion 11 is located in the second cavity 65, along the radial direction of the valve device 100, the outer periphery of the first limiting portion 11 directly abuts or indirectly abuts against the side wall forming the second cavity 65. After the first limiting portion 11 is inserted into the second cavity 65, the rotation axis of the valve device 100 in step S2 is determined, and the first limiting portion 11 can be used as a support point for the rotation of the valve device 100. The side wall forming the second cavity 65 is a cylindrical surface or a conical surface, which can facilitate the rotation of the first limiting portion 11. Along the axial direction of the valve device 100, the projection of the first limiting portion 11 on the first plane is located inside the projection of the main body portion 12 on the first plane, which can reduce the friction of the valve body assembly 10 when it is inserted into the installation cavity 63. Specifically, the first limiting portion 11 is cylindrical or conical, and the first limiting portion 11 is coaxially arranged with the second side portion.

[0046] The first limiting portion 11 includes a second sealing member 52 and a main body portion 113, and the second sealing member 52 surrounds the main body portion 113 along the circumferential direction of the valve device 100; the valve body assembly 10 has a third connecting port 36, and the third connecting port 36 is located in the first limiting portion 11, and along the axial direction of the valve device 100, the second sealing member 52 is located between the third connecting port 36 and the main body portion 12; along the radial direction of the valve device 100, the second sealing member 52 is located between the main body portion 113 and the side wall forming the second cavity 65, one side of the second sealing member 52 abuts against the main body portion 113, and the other side of the second sealing member 52 abuts against the side wall forming the second cavity 65, and the second sealing member 513 surrounds the first limiting portion 11 along the circumferential direction.

[0047] The first sealing member 51 includes a third sealing portion 514, the valve body assembly 10 includes a step surface portion 15, the step surface portion 15 is close to the driving portion 8 relative to the main body portion 12, and the step surface portion 15 faces away from the driving portion 8, the third sealing portion 514 is fixedly connected or limitedly connected to the step surface portion 15, and along the axial direction of the valve device 100, the third sealing portion 514 abuts against the wall forming the installation cavity 63, thereby achieving axial sealing. Along the axial direction of the valve device 100, the projection of the third sealing portion 514 on the first plane is located on the inner side of the projection of the step surface portion 15 on the first plane, and when performing step S1, the friction between the third sealing portion 514 and the wall forming the installation cavity 63 can be reduced.

[0048] Along the axial direction of the valve device 100 , one end of the first sealing portion 512 is integrally structured with the second sealing portion 513 , and the other end of the first sealing portion 512 is integrally structured with the third sealing portion 514 , thereby forming a sealing structure surrounding the first communication port 35 .

[0049] The first seal 51 is fixedly connected or limitedly connected to the valve body assembly 10. It should be noted that the "limited connection" in the present application includes a detachable connection, such as interference fit, snap-on connection, etc., and the "fixed connection" in the present application includes a non-detachable connection, such as insert injection molding, bonding, vulcanization connection, etc. In the present embodiment, the first seal 51 is fixedly connected to the peripheral portion 32 through a vulcanization process and is sealed, so that the first seal 51 can be fixed to the valve body assembly 10 more firmly, reducing the risk of leakage and reducing the risk of the first seal 51 falling off when the valve body assembly 10 is inserted into the installation cavity 63. Specifically, the valve body assembly 10 is made of metal, such as stainless steel, and the first seal 51 is at least partially an elastic member, and the material of the first seal 51 includes rubber, such as EPDM. Specifically, the valve body assembly 10 has a groove 34 recessed in the outer peripheral portion 32, and at least part of the first sealing portion 512 is located in the groove 34. The first sealing portion 512 can be vulcanized or interference fit with the wall forming the groove 34, further increasing the firmness of the connection between the first sealing portion 512 and the valve body assembly 10.

[0050] In this embodiment, the main body 12 has a second communication port 37. The first communication port 35 and the second communication port 37 are respectively located on opposite sides of the main body 12 along the radial direction of the valve device 100. The first sealing portion 512 is located between the first communication port 35 and the second communication port 37 along the circumferential direction of the valve device 100. The first communication port 35 and the second communication port 37 are located at substantially the same position in the axial direction of the valve device 100, which can reduce the axial length of the valve body assembly 10, making the valve body assembly 10 more compact and occupying less space of the communication assembly 6. Specifically, the third sealing portion 514 and the second sealing portion 513 both surround the main body 12 along the circumferential direction of the valve device 100, so that a portion of the first sealing member 51 surrounds the second communication port 37, and the second communication port 37 can be sealed.

[0051] The connecting component 6 has a first hole 61 and a second hole 62. Both the first hole 61 and the second hole 62 have openings in the wall forming the first cavity 64. The first hole 61 is connected to the first connecting port 35, and the second hole 62 is connected to the second connecting port 37. The connecting component 6 has a third hole 601. The third hole 601 has an opening in the wall forming the second cavity 65. The third hole 601 is connected to the third connecting port 36.

[0052] The valve device 100 further includes a sealing seat assembly 4, which is located between the outer peripheral surface of the valve core 7 and the valve body 3 along the radial direction of the valve device 100. The outer peripheral surface of the valve core 7 is spherical or quasi-spherical, and the sealing seat assembly 4 is slidably matched with the outer peripheral surface of the valve core 7. In other embodiments, the outer peripheral surface of the valve core 7 may be quasi-cylindrical or quasi-conical.

[0053] The valve core 7 has a communication passage 71, and the communication passage 71 can be communicated with the first communication port 35. In this embodiment, the communication passage 71 is connected to the third communication port 36. When the valve core 7 rotates to a certain angle, the third communication port 36 can be communicated with the first communication port 35, thereby making the first hole 61 communicate with the second hole 62. By controlling the rotation angle of the valve core 7, the third communication port 36 can be communicated with at least one of the first communication port 35 and the second communication port 37.

Although the present invention has been described in detail in this specification with reference to the above embodiments, it should be understood by those skilled in the art that the present invention can still be modified or replaced by equivalents, and all technical solutions and improvements thereof that do not depart from the spirit and scope of the present invention should be included in the scope of the claims of the present invention.
