[0046] Embodiments of the present invention are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0047] In the description of this invention, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0048] The following is for reference. Figures 1-13 A multi-channel switching valve 10000 according to an embodiment of the present invention is described, wherein the multi-channel switching valve 10000 can be applied to any system that requires flow channel switching, such as in electric vehicles.

[0049] like Figure 1 and Figure 6 As shown, a multi-channel switching valve 10000 according to an embodiment of the present invention includes: a valve housing 1, multiple on / off valve bodies 2, and a drive assembly 3. The valve housing 1 includes an inlet tank layer 10 and an outlet tank layer 11 spaced apart. The inlet tank layer 10 includes multiple inlet tanks, each with an inlet valve port 12. The outlet tank layer 11 includes multiple outlet tanks, each with an outlet valve port 13. Each inlet tank communicates with at least one outlet tank through at least one through hole 106. Specifically, the valve housing 1 has multiple inlet valve ports 12, each corresponding to one inlet tank, and each inlet tank has at least one through hole 106. The valve housing 1 also has multiple outlet valve ports 13, each corresponding to one outlet tank, and each outlet tank communicates with at least one inlet tank through at least one through hole 106. Specifically, the inlet tank layer 10 and the outlet tank layer 11 can be spaced apart in the vertical direction.

[0050] Multiple on / off valve bodies 2 are configured one-to-one with multiple through holes 106. Each on / off valve body 2 can be moved to open or block the corresponding through hole 106. In other words, each through hole 106 is opened or blocked by the corresponding on / off valve body 2.

[0051] The drive component 3 cooperates with multiple on / off valve bodies 2 to control the working state of each on / off valve body 2 so that each inlet valve 12 in at least a portion of the inlet valve ports 12 is switched to be connected with at least two outlet valve ports 13.

[0052] Specifically, by controlling the working state of each on / off valve body 2 through the drive component 3, the opening or closing of each through hole 106 can be controlled, thereby controlling whether the corresponding inlet and outlet water tanks are connected. Furthermore, by controlling the opening of different through holes 106, at least some of the inlet valve ports 12 can be connected to different outlet valve ports 13, thus enabling the multi-channel switching valve 10000 to have different flow channels to meet different mode requirements. It should be noted that "at least some of the inlet valve ports 12 are connected to at least two outlet valve ports 13" means that each inlet valve port 12 can be connected to at least two outlet valve ports 13; or only a few inlet valve ports 12 are connected to at least two outlet valve ports 13, and some inlet valve ports 12 are connected to only one outlet valve port 13.

[0053] It is understandable that the number of inlet valve ports 12 and outlet valve ports 13 can be set according to actual conditions. For example, there can be five, six, seven, eight, etc., for the inlet valve ports 12. The number of through holes 106 corresponding to each inlet tank can also be selected according to actual conditions. No specific limitation is made here. Please refer to the following. Figures 1-3 The following explanation is based on the example of three inlet valves 12 and three outlet valves 13.

[0054] In some examples of the present invention, such as Figure 1 As shown, the valve housing 1 has six valve ports, including three inlet valve ports 12 and three outlet valve ports 13, as follows: Figure 2 As shown, the water inlet layer 10 includes three water inlet tanks: a first water inlet tank 101, a second water inlet tank 102, and a third water inlet tank 103. The first water inlet tank 101 is provided with a first valve port 121, a first through hole 1060, and a second through hole 1061. The second water inlet tank 102 is provided with a third valve port 123, a third through hole 1062, a fourth through hole 1063, and a fifth through hole 1064. The third water inlet tank 103 is provided with a fifth valve port 125 and a sixth through hole 1065.

[0055] like Figure 3 As shown, the water outlet layer 11 includes three water outlets, namely the first water outlet 110, the second water outlet 111, and the third water outlet 112. The first water outlet 110 is provided with a second valve port 122, the second water outlet 111 is provided with a fourth valve port 124, and the third water outlet 112 is provided with a sixth valve port 126. The first water outlet 110 is provided with a second through hole 1061 and a third through hole 1062, the second water outlet 111 is provided with a fourth through hole 1063, and the third water outlet 112 is provided with a first through hole 1060, a fifth through hole 1064, and a sixth through hole 1065.

[0056] The liquid, such as coolant, in the first inlet tank 101 can selectively flow to the first outlet tank 110 or the third outlet tank 112 through the first through hole 1060 or the second through hole 1061, thereby allowing the first valve port 121 to selectively communicate with the second valve port 122 or the sixth valve port 126.

[0057] Liquid, such as coolant, in the second inlet tank 102 can selectively flow to the first outlet tank 110, the second outlet tank 111, or the third outlet tank 112 through the third through hole 1062, the fourth through hole 1063, or the fifth through hole 1064, thereby allowing the third valve port 123 to selectively communicate with the second valve port 122, the fourth valve port 124, or the sixth valve port 126.

[0058] Liquid, such as coolant, in the third inlet tank 103 can flow to the third outlet tank 112 through the sixth through hole 1065, that is, the fifth valve port 125 can be connected to the sixth valve port 126.

[0059] As can be seen from the above analysis, the first valve port 121 can be switched to connect with the second valve port 122 and the sixth valve port 126 according to specific needs, the third valve port 123 can be switched to connect with the second valve port 122, the fourth valve port 124 and the sixth valve port 126, and the fifth valve port 125 can be controlled to connect with the sixth valve port 126, so that the multi-channel switching valve 10000 according to the embodiment of the present invention has multiple modes.

[0060] It is understandable that when the valve housing 1 has six valve ports, the configuration of the through holes 106 is not limited to this. For example, the first water inlet trough 101 can be provided with three through holes 106, so that the first water inlet trough 101 can selectively switch to connect with the first water outlet trough 110, the second water outlet trough 111 and the third water outlet trough 112. The configuration of the through holes 106 can be set according to actual needs, as long as each of at least some of the water inlet valve ports 12 can switch with at least two water outlet valve ports 13.

[0061] In summary, according to the embodiments of the present invention, the multi-channel switching valve 10000 can control the connection between the corresponding outlet valve 13 and different inlet valves 12 by controlling the opening and closing of the through holes 106 in each outlet tank. This allows the multi-channel switching valve 10000 to have multiple modes, and the number of inlet valves 12 and outlet valves 13 is unlimited and can be set according to needs, thereby expanding the applicability of the multi-channel switching valve 10000. Simultaneously, mode switching can be achieved by controlling the operating state of multiple on / off valve bodies 2 through the drive component 3, making the mode switching method of the multi-channel switching valve 10000 simple and reliable. Furthermore, since multiple inlet valves 12 and multiple outlet valves 13 can be regularly distributed on the valve housing 1, for example, distributed on opposite side walls of the valve housing 1, the multi-channel switching valve 10000 occupies a small volume, facilitating installation.

[0062] In some embodiments of the present invention, such as Figure 1 , Figure 4 , Figure 6 As shown, each on / off valve body 2 is movable relative to the through hole 106. The drive assembly 3 includes multiple cams 30, multiple reset members 31, and a drive member 32. The multiple cams 30 are respectively configured to correspond one-to-one with the multiple on / off valve bodies 2 to push the on / off valve bodies 2 to close the through hole 106. The multiple reset members 31 are disposed on the valve housing 1 and are respectively configured one-to-one with the multiple on / off valve bodies 2. Each reset member 31 pushes the corresponding on / off valve body 2 to move in the direction of opening the through hole 106. The drive member 32 cooperates with the multiple cams 30 to drive the multiple cams 30 to rotate. Specifically, each on / off valve body 2 is provided with one cam 30 and one reset member 31. The drive member 32 can drive the cam 30 to rotate. Each cam 30 has a mating position, including a high position and a low position. When the cam 30 rotates, the high position presses down on the corresponding on / off valve body 2, causing the on / off valve body 2 to close the corresponding through hole 106. When the cam 30 rotates and its lower part contacts the on / off valve body 2, the on / off valve body 2 opens the through hole 106 under the action of the reset member 31. That is, when the cam 30 rotates, it gradually presses down on the on / off valve body 2 and gradually releases it upward. This makes the structure of the drive assembly 3 simple and the driving method of the on / off valve body 2 simple and reliable.

[0063] Furthermore, each cam 30 is provided with multiple engagement positions that contact and engage with the on / off valve body 2. These engagement positions include a low position and a high position. When the high position contacts the on / off valve body 2, the on / off valve body 2 closes the through hole 106. When the low position contacts the on / off valve body 2, the reset member 31 pushes the on / off valve body 2 to open the through hole 106. At least some of the cams 30 have different shapes, thereby satisfying the various mode requirements of the multi-channel switching valve 10000.

[0064] Understandably, the multi-channel switching valve 10000 has multiple modes. The number of engagement positions for each cam 30 is the same as the number of modes, allowing the operating state of the on / off valve body 2 corresponding to each cam 30 to match the needs of multiple modes. The multiple engagement positions of the cam 30 can be set to high or low positions as needed. When the cam 30 rotates from one engagement position to another, it can control the multi-channel switching valve 10000 to switch from one mode to another. Furthermore, each engagement position of the cam 30 can be formed into an arc surface structure, allowing the cam 30 to make line contact with the on / off valve body 2. Compared to surface contact, line contact ensures that the cam 30 can push the on / off valve body 2 to block the through hole 106 during rotation, ensuring the operational reliability of the multi-channel switching valve 10000. Furthermore, the engagement positions of the cam 30 can be transitioned by inclined surfaces, thus simplifying the structure of the cam 30.

[0065] For example, Figure 1 , Figure 4 and Figure 5 As shown, in some examples of the present invention, the multi-channel switching valve 10000 has four modes (e.g., Figure 5 (As shown by numbers 1, 2, 3, and 4 in the diagram), the multi-channel switching valve 10000 includes six on / off valve bodies 2, and six cams 30, with one cam 30 corresponding to each through-hole 106, as shown in the diagram. Figure 5 As shown, each cam 30 has four mating positions to match four modes. The shapes of the six cams 30 are set according to the corresponding modes of the through-hole 106. A cam 30 can switch from one mode to another by rotating 110 degrees. Taking the cam 30 corresponding to the first through-hole 1060 as an example, in modes one, two, and four, the cam is in the high mating position, causing the on / off valve body 2 to close the first through-hole 1060. In mode three, the cam is in the low mating position, and the first through-hole 1060 is open. Specifically, the cam 30 can rotate 110 degrees from the first mating position to the second mating position, causing the multi-channel switching valve 10000 to switch from mode one to mode two. The cam 30 continues to rotate 110 degrees from the second mating position to the third mating position, and then rotates another 110 degrees to switch from the third mating position to the fourth mating position. Then the cam 30 reverses to rotate from the fourth mating position back to the third mating position, and this rotation is repeated to switch back to the first mating position. It is understandable that... Figure 6 As shown, the multi-channel switching valve 10000 may also include five on / off valve bodies 2 and five cams 30. Each through hole 106 is provided with one cam 30. The number of on / off valve bodies 2 and cams 30 can be limited according to actual needs, such as the number of inlet valve ports 12 and the number of outlet valve ports 13.

[0066] Optionally, each reset element 31 is a spring, thus simplifying the structure of the reset element 31. When the cam 30 presses down on the on / off valve body 2 to close the through hole 106, the spring is compressed. When the lower part engages with the on / off valve body 2, the spring opens to move the on / off valve body 2 to open the through hole 106. Of course, it is understood that the reset element 31 can also be a structure such as an elastic metal sheet.

[0067] In some embodiments of the present invention, such as Figure 1 As shown, the drive component 32 includes a drive motor 320 and a connecting rod 321. The drive motor 320 is connected to the connecting rod 321 to drive the connecting rod 321 to rotate. Multiple cams 30 are mounted on the connecting rod 321 and are driven by the connecting rod 321 to rotate synchronously. That is, multiple cams 30 are driven to rotate synchronously by the connecting rod 321, and the drive motor 320 drives the connecting rod 321 to rotate, thereby driving the multiple cams 30 to rotate synchronously, achieving the purpose of pushing multiple on / off valve bodies 2 to move. Thus, the structure of the drive component 32 is simple and reliable. Of course, it is understood that the structure of the drive component 32 is not limited to this. As long as the drive component 32 can drive multiple cams 30 to rotate to control the movement of multiple on / off valve bodies 2, it is acceptable. For example, the drive component 32 can also include multiple drive motors 320, with each drive motor 320 corresponding to one of the multiple cams 30, and each drive motor 320 driving the corresponding cam 30 to rotate.

[0068] Specifically, such as Figure 6 As shown, adjacent cams 30 can be connected by connectors 33 to form a single mounting unit. The multiple connected cams 30 are fitted onto the linkage 321, facilitating the assembly of the multiple cams 30. Furthermore, the multiple cams 30 and the connectors 33 are formed as a single unit.

[0069] It should be noted that the structure of the drive assembly 3 is not limited to the above description. As long as the drive assembly 3 can drive multiple on / off valve bodies 2 to move, it is acceptable. For example, the drive assembly 3 may include multiple drive elements 32 and multiple push rods. The multiple drive elements 32 are respectively matched with the multiple push rods. Each drive element 32 drives the corresponding push rod to move. The multiple push rods are respectively matched with the multiple on / off valve bodies 2. When each push rod moves, it drives the corresponding on / off valve body 2 to move to control its working state.

[0070] like Figure 6 As shown, the multi-channel switching valve 10000 also includes a housing 5, which is mounted on the valve body 1. The drive assembly 3 is housed within the housing 5, and each on / off valve body 2 extends into the housing 5 to cooperate with the drive assembly 3. Thus, by providing the housing 5, the drive assembly 3 can be protected. Specifically, the housing 5 can be fixed to the valve body 1, thereby improving the overall integrity of the multi-channel switching valve 10000 and facilitating its installation.

[0071] Furthermore, the bottom of the housing 5 is provided with multiple through holes, each of which corresponds to a multiple on / off valve body 2. Each on / off valve body 2 extends into the housing 5 through the through hole to cooperate with the drive assembly 3. The multiple through holes can play a positioning role for the on / off valve body 2.

[0072] like Figure 1 As shown, in some embodiments of the present invention, each on / off valve body 2 is provided with a first sealing ring 4. When the on / off valve body 2 blocks the through hole 106, the first sealing ring 4 cooperates with the inner wall of the through hole 106. This further ensures that there is no communication between the corresponding inlet and outlet water channels when the through hole 106 is closed, further ensuring the reliability of the multi-channel switching valve 10000. Furthermore, the on / off valve body 2 is provided with a groove for installing the first sealing ring 4.
