DETAILED DESCRIPTION OF THE INVENTION

[0009] The features and exemplary embodiments of each aspect of the present application will be described in detail below, and in order to make the objectives, technical solutions and advantages of the present application clearer, the present application will be further described below in combination with drawings and specific examples. In this document, relational terms such as "first" and "second" are used merely to distinguish one from another element having the same name, and do not necessarily require or imply the existence of any such actual relation or order between these elements.

[0010] DETAILED DESCRIPTION OF THE INVENTION Embodiments of the present application provide a fluid control assembly that can be used in a vehicle thermal management system, specifically a coolant circulation system, and that can perform the functions of conducting and switching fluid passages in the thermal management system.

[0011] As shown in FIGS. 1 to 13, the fluid control assembly 1 includes a connecting body 10, a valve body 20, and a sealing member 30. The fluid control assembly 1 has a storage chamber 101 and a communication port 102. The communication port 102 is adjacent to the storage chamber 101 and communicates with the storage chamber 101. The connecting body 10 includes a side wall portion 11 that forms at least a part of the peripheral wall of the storage chamber 101. The communication port 102 is located on the side wall portion 11. The connecting body 10 can further include a top wall portion and a bottom cover 12. The side wall portion 11, the top wall portion, and the bottom cover 12 surround the storage chamber 101. At least a portion of the side wall 11 is located between the top wall 11 and the bottom cover 12, one of the top wall 11 and the bottom cover 12 can be integrally injection molded with the side wall 11 to form a one-piece structure, and the other is sealingly connected to the side wall 11, at least a portion of the valve element 20 is located in the accommodating chamber 101 and the valve element 20 can be rotated, and at least a portion of the sealing member 30 is located between the side wall 11 and the valve element 20 along the radial direction of the side wall 11 and is used to achieve sealing of the fluid control assembly 1. Optionally, the fluid control assembly 1 further includes a drive assembly 50 including a drive member, which can include a motor or a combination of a motor and a group of transmission gears, and the drive member and the valve element 20 are communicatively connected so that the drive member rotates the valve element 20.

[0012] The sealing member 30 includes holes 31 that correspond to the communication ports 102 and communicate with each other. Alternatively, the sealing member 30 may include holes 31 that are equal in number to the communication ports 102 and communicate with each other in a one-to-one correspondence. As shown in Figures 9 to 13, the orthogonal projections of the holes 31 of the sealing member 30 are arranged at intervals along the axial direction of the sealing member 30 in the circumferential direction of the valve body 20. The holes include first holes 32 and second holes 33 that are arranged at intervals along the axial direction of the sealing member 30. In this case, the first holes 32 and second holes 33 that are arranged at intervals along the circumferential direction of the valve body 20 are located at different heights of the sealing member 30. Compared to arranging all the holes at intervals along the circumferential direction of the valve body and providing all the holes at the same height of the sealing member, the sealing member 30 of the flow control device provided in the embodiments of the present application facilitates increasing the wall distance between two holes 31 located at the same height, making it easier for the sealing member 30 to be pressed against the wall when the valve body 20 is rotated, thus facilitating improvement of the sealing performance of the fluid control assembly.

[0013] The first sealing member 30 includes a first fitting portion 34 to prevent rotation of the first sealing member 30, and as shown in FIG. 11, the connecting body 10 includes a position limiting portion 14, and as shown in FIG. 6, the first fitting portion 34 and the position limiting portion 14 are connected to limit the position, for example, the first fitting portion 34 may be one of a hole structure and a protrusion structure, and the position limiting portion 14 may be the other of a hole structure and a protrusion structure, and the protrusion structure fits into the hole structure to limit the position. The first sealing member 30 includes a first circumferential wall portion 35 and a second circumferential wall portion 36, and along the axial direction of the first sealing member 30, the orthogonal projections of the first circumferential wall portion 35 and the orthogonal projections of the second circumferential wall portion 36 are arranged along the circumferential direction of the valve body 20. The first circumferential wall portion 35 is located between the first sub-hole passage 321 and the third sub-hole passage 323, and the first circumferential wall portion 35 and the second sub-hole passage 322 are respectively provided on both radial sides of the first sealing member 30. A corresponding central angle a1 of the first circumferential wall portion 35 is greater than 90 degrees and less than 180 degrees. The second circumferential wall portion 36 is located between the fourth sub-hole passage 331 and the fifth sub-hole passage 332, and a corresponding central angle a2 of the second circumferential wall portion 36 is greater than 180 degrees.

[0014] 1 to 8 , in some embodiments, the fluid control assembly 1 has a flow passage 43 communicating with a corresponding communication port 102, and the fluid control assembly 1 further includes a first flow passage plate 41 forming at least a portion of the wall of the flow passage 43. The first flow passage plate 41 extends from the outer surface of the side wall portion 11 in a direction away from the receiving chamber 101, and the first flow passage plate 41 can be integrally injection molded with the connecting body 10 to form a one-piece structure. This arrangement allows the first flow passage plate 41 to have a good sealing performance with the connecting body 10, facilitates reducing the number of parts of the fluid control assembly 1, and improves the assembly efficiency of the fluid control assembly 1. Furthermore, the fluid control assembly 1 can further include a second flow passage plate 42 sealingly disposed with the first flow passage plate 41 and forming the wall of the flow passage 43. Optionally, the second flow passage plate 42 can be welded to the first flow passage plate 41.

[0015] In order to achieve corresponding communication between the communication ports 102 and the hole passages 31, in some embodiments, as shown in Figures 3 to 8, the orthogonal projections of the communication ports 102 are arranged at intervals along the circumferential direction of the valve body 20 along the axial direction of the side wall portion 11, and the communication ports 102 include a first communication port 1021 and a second communication port 1022 arranged at intervals along the axial direction of the valve side wall portion 11, and the first communication port 1021 corresponds to and communicates with the first hole passage 32, and the second communication port 1022 corresponds to and communicates with the second hole passage 33. Optionally, the communication ports 102 may include three first communication ports 1021 and two second communication ports 1022, and the three first communication ports 1021 may be located at the same height of the fluid control assembly 1, and the two second communication ports 1022 may be located at the same height of the fluid control assembly 1, with the orthogonal projections of the three first communication ports 1021 being adjacent to each other and the orthogonal projections of the two second communication ports 1022 being adjacent to each other along the axial direction of the valve body 20. As can be understood, in this context, the orthogonal projection of each communication port along the axial direction of the side wall portion 11 includes an area surrounded and limited by the orthogonal projection of the wall of each communication port along the axial direction of the valve body 20, and in this context, the axial directions of the side wall portion 11, the valve body 20, and the sealing member 30 are parallel or coincident.

[0016] 9 to 13 , the hole passages 31 of the sealing member 30 include at least one first hole passage 32 and at least two second hole passages 33, and the orthogonal projections of all the first hole passages 32 are adjacent to each other along the axial direction of the sealing member 30, and the orthogonal projections of all the second hole passages 33 are adjacent to each other along the axial direction of the sealing member 30. In a specific implementation, the hole passages 31 of the sealing member 30 include three first hole passages 32 and two second hole passages 33, and the three first hole passages 32 can be located at the same height of the sealing member 30, and the two second hole passages 33 can be located at the same height of the sealing member 30, and the orthogonal projections of the three first hole passages 32 are adjacent to each other along the axial direction of the sealing member 30, and the orthogonal projections of the two second hole passages 33 are adjacent to each other along the axial direction of the sealing member 30, and in this embodiment, the angle between two adjacent first hole passages 32 may be 90 degrees, and the angle between two adjacent second hole passages 33 may be 45 degrees. In this case, at the height where the first hole passage 32 of the sealing member 30 is located, approximately half of the wall portion is free of hole passages, and at the height where the second hole passage 33 of the sealing member 30 is located, approximately half or more of the wall portion is free of hole passages. Compared to arranging all of the hole passages circumferentially at the same height of the sealing member, the fluid control assembly provided in the embodiments of the present application can easily increase the wall distance between two hole passages 31 located at the same height, and can easily improve the sealing performance of the fluid control assembly.

[0017] When the valve element 20 rotates, due to factors such as the control precision of the drive assembly 50, delay in signal transmission, or the rotational moment of inertia of the valve element member 20, the valve element 20 may stop before rotating to the set angle, or continue to rotate after exceeding the set angle, which makes it easy for a rotation tolerance to occur in the valve element 20. For example, the rotation tolerance angle of the valve element member 20 may be ±5 degrees, that is, the valve element 20 may stop when rotating 5 degrees before the set angle, or may stop when continuing to rotate 5 degrees after exceeding the set angle. Therefore, The sealing member 30 contacts the valve body member 20 throughout the stroke range of the valve body member 20 as it rotates, thereby providing the sealing member 30 with good sealing performance. In this embodiment, the first hole 32 and the second hole 33 are arranged at intervals along the axial direction of the sealing member 30, which increases the wall distance between the two hole paths 31 at the same height, making it easier for the valve body 20 to contact the wall of the sealing member 30 throughout the stroke range and facilitating the improvement of the sealing performance of the sealing member 30.

[0018] As shown in Figures 14 to 18, in some embodiments, the valve body 20 includes a first group of chambers 21, a partition plate 23, and a second group of chambers 22, and along the axial direction of the valve body 20, the partition plate 23 is located between the first group of chambers 21 and the second group of chambers 22, and the first group of chambers 21 has at least two first communicating chambers 211 that are spaced apart from each other, and the second group of chambers 22 has at least two second communicating chambers 221 that are spaced apart from each other, and the partition plate 23 has through holes 231, and some of the first communicating chambers 211 and some of the second communicating chambers 221 are connected to each other through the through holes 231, and by rotating the valve body 20, the communication ports 102 corresponding to the first hole 32 and the second hole 33 can be connected to each other through the first communicating chambers 211, the through holes 231, and the second communicating chambers 221. The above arrangement allows the fluid control assembly to achieve a fluid control function.

[0019] 3 to 21, the communication port 102 of the fluid control assembly includes a first communication port 1021 and a second communication port 1022, the first communication port 1021 includes a first port P1, a second port P2, and a third port P3, the second communication port 1022 can include a fourth port P4 and a fifth port P5, and the orthographic projection of the first port P1, the orthographic projection of the second port P2, the orthographic projection of the third port P3, the orthographic projection of the fourth port P4, and The orthogonal projections of the five ports P5 are arranged in order along the circumferential direction of the valve body 20. In the drawings, the orthogonal projections of the above five ports are illustrated as being arranged counterclockwise along the circumferential direction of the valve body 20 as an example. Alternatively, the orthogonal projections of the first port P1, the orthogonal projections of the second port P2, the orthogonal projections of the third port P3, the orthogonal projections of the fourth port P4 and the orthogonal projections of the fifth port P5 may be arranged clockwise along the circumferential direction of the valve body 20.

With the above arrangement, multiple flow methods for the fluid control assembly can be realized.
