Description

Technical Field

[0001] This application relates to a drive mechanism, and more particularly, to a drive mechanism for a grouped drive valve. Background Art

[0002] A regulating valve is applied inside a vehicle. The regulating valve controls the flow path of the coolant by connecting different thermal control channels inside the vehicle, and regulates the temperature of each component inside the vehicle. The regulating valve generally includes a housing and a valve body disposed inside the housing. The housing is provided with housing flow ports, and each housing flow port is connected to the temperature regulating system inside the vehicle through a pipeline. The valve body is provided with an opening. The valve body can rotate under the drive of an actuator so that the opening part of the valve body aligns with the housing flow port, thereby connecting different flow ports of the housing, and further connecting different temperature regulating channels in the temperature regulating system. Among them, a plurality of seals are provided between the flow ports of the valve body and the housing to ensure the sealing performance of both the connected and unconnected channels. When the valve body rotates, the seal is pressed tightly between the housing and the valve body, and a pressing force is applied to it. The frictional resistance caused by the seal hinders the rotation of the valve body, and the frictional resistance needs to be overcome to drive the valve body to rotate.

[0003] As more and more components inside the vehicle need to be regulated, the number of flow ports on the housing is increasing.

[0062] Figure 1A is a perspective view of a regulating valve 100 according to an embodiment of the present application; Figure 1B is Figure 1A an exploded view of the regulating valve 100 shown in Figure 1C is Figure 1A a vertical downward sectional view of the regulating valve 100 shown in Figure 1A along the section line A-A in Figure 1A - 1C In order to clearly show the main components in the regulating valve 100, Figure 1A - 1CAs shown in the figure, the regulating valve 100 includes a housing 101, a first valve body 132, a second valve body 134, a third valve body 136, and a fourth valve body 138. The housing 101 has a first cavity 112 and a second cavity 114. The first valve body 132, the second valve body 134, and the fourth valve body 138 are arranged in the first cavity 112, and the third valve body 136 is arranged in the second cavity 114. A sleeve 155 is provided at the bottom of the rotating shaft 162 of the first valve body 132, and the sleeve 155 is sleeved on the top of the rotating shaft 164 of the second valve body 134, so that the first valve body 132 and the second valve body 134 can rotate around the same first axis X. The lower part of the rotating shaft 166 of the third valve body 136 passes through the first transverse partition plate 120 of the first cavity 112 and the second cavity 114 and then extends into the first cavity 112. A sleeve 156 is provided at the bottom of the third valve body 136, and the sleeve 156 is sleeved on the top of the rotating shaft 168 of the fourth valve body 138, so that the third valve body 136 and the fourth valve body 138 can rotate around the same second axis Y.

[0063] The regulating valve 100 further includes a drive shaft 118. The drive shaft 118 is arranged in the first cavity 112 and can rotate around a third axis Z. The first valve body 132 and the second valve body 134 are arranged on the left side of the drive shaft 118, and the third valve body 136 and the fourth valve body 138 are arranged on the right side of the drive shaft 118. The regulating valve 100 further includes a first clutch structure, a second clutch structure, a third clutch structure, and a fourth clutch structure. When the drive shaft 118 rotates, the first valve body 132, the second valve body 134, the third valve body 136, and the fourth valve body 138 can selectively rotate together with the drive shaft 118 through the first clutch structure, the second clutch structure, the third clutch structure, and the fourth clutch structure respectively.

[0064] Figure 2 is Figure 1A an exploded view of the housing 101 shown in the figure. As Figure 2 shown in the figure, the housing 101 includes a housing body 202 and a cover 203. The size of the cover 203 can match the size of the pipe opening 375 of the pipe 370 in the housing body 202, so that the cover 203 can be installed on the pipe opening 375 and block the pipe opening 375, so that the housing 101 cannot flow in or out from the pipe opening 375.

[0065] Figure 3A is a perspective view of the housing body 202 shown in the figure, viewed from top to bottom in front of the housing 101; Figure 2 Figure 3B is a perspective view of the housing body 202 shown in the figure, viewed from bottom to top behind the housing 101; Figure 2 Figure 3C and 3D are respectively Figure 2 the top view and the bottom view of the housing body 202 shown in the figure.​​Figure 3E is Figure 2 a vertical downward sectional view of the housing body 202 along the Figure 3A B-B section line in the figure to show more structural details inside the housing body 202. For better description of the structure of the housing body 202, in this application, the extending direction of the first axis X, the second axis Y and the third axis Z is taken as the first direction, the horizontal connection direction of the first axis X and the third axis Z is taken as the second direction, and the direction perpendicular to the first direction and the second direction is taken as the third direction.

[0066] As Figure 3A - 3E shown, the housing body 202 has a top plate. The top plate includes a first transverse partition plate 120, a second transverse partition plate 323 and a vertical partition plate 324. The first transverse partition plate 120 and the second transverse partition plate 323 are arranged to have a height difference in the first direction to form a stepped portion 310. A first cavity 112 is arranged below the first transverse partition plate 120 and the second transverse partition plate 323, and a second cavity 114 is arranged above the first transverse partition plate 120, so that the top of the second cavity 114 is partially higher than the top of the first cavity 112 in the first direction.

[0067] A perforation 391 is provided in the first transverse partition plate 120. The lower part of the third valve body 136 can pass through the perforation 391, so that the lower part of the third valve body 136 extends into the first cavity 112, and the third valve body 136 can rotate around the second axis Y.

[0068] The first bottom plate 395 of the first cavity 112 has a concave portion 396 for receiving the lower part of the fourth valve body 138. Since the upper part of the fourth valve body 138 is connected to the lower part of the third valve body 136, and the lower part of the fourth valve body 138 is received in the concave portion 396 of the first bottom plate 395, the fourth valve body 138 can be arranged in the first cavity 112 and can rotate around the second axis Y.

[0069] The second transverse partition plate 323 has a concave portion 393 for receiving the upper part of the first valve body 132. The second bottom plate 397 of the first cavity 112 has a concave portion 398 for receiving the lower part of the second valve body 134. Since the lower part of the first valve body 132 and the upper part of the second valve body 134 are sleeved together, the first valve body 132 and the second valve body 134 can be arranged in the first cavity 112 together and can rotate around the first axis X.

[0070] The second transverse partition plate 323 also has a concave portion 394 for receiving the upper part of the drive shaft, so that when the actuator drives the drive shaft to rotate, the drive shaft can rotate around the third axis Z.

[0071] Figure 3F isFigure 2 A sectional view of the housing body 202 along the Figure 3A parallel direction of the C-C section line in the figure to more clearly show the shape of the first cavity 112. As Figure 3F shown, the shape of the first cavity 112 is generally three intersecting cylinders, thus forming the first cut cylinder cavity 311, the second cut cylinder cavity 312 and the third cut cylinder cavity 313. The first valve body 132 and the second valve body 134 are arranged in the first cut cylinder cavity 311, the drive shaft 118 is arranged in the second cut cylinder cavity 312, and the fourth valve body 138 is arranged in the third cut cylinder cavity 313. Among them, the central axis M of the first cut cylinder cavity 311 coincides with the first axis X, the central axis N of the second cut cylinder cavity 312 coincides with the third axis Z, and the central axis O of the third cut cylinder cavity 313 coincides with the second axis Y.

[0072] Combined Figure 3A - 3E it can be seen that a first group of flow ports are provided on the cavity wall of the first cavity 112. The first group of flow ports includes a first flow port 361 arranged along the third direction and a second flow port 362 arranged in the reverse direction of the third direction. The first flow port 361 and the second flow port 362 are set at the same height in the first direction, and the heights of the first flow port 361 and the second flow port 362 are set to enable the first flow port 361 and the second flow port 362 to cooperate with the first valve body 132. In other words, when the first valve body 132 rotates, it can selectively connect or disconnect the first flow port 361 and / or the second flow port 362.

[0073] The first group of flow ports further includes a third flow port 363. The third flow port 363 is arranged within the range of the included angle between the reverse direction of the second direction and the third direction, and its height set in the first direction is lower than that of the first flow port 361 and the second flow port 362. The height of the third flow port 363 is set to enable the third flow port 363 to cooperate with the second valve body 134. In other words, when the second valve body 134 rotates, it can selectively connect or disconnect the third flow port 363.

[0074] The first group of flow ports further includes a fourth flow port 364. The fourth flow port 364 is arranged within the range of the included angle between the reverse direction of the second direction and the reverse direction of the third direction, and its height set in the first direction is slightly lower than that of the third flow port 363. The set height of the fourth flow port 364 is lower than the set height of the second valve body 134. In other words, no matter what angle the second valve body 134 rotates to, the fourth flow port 364 remains in fluid communication with the first cavity 112.

[0075] Among them, each of the first communication port 361, the second communication port 362, the third communication port 363, and the fourth communication port 364 is arranged around the first cut cylindrical cavity 311 with the central axis M of the first cut cylindrical cavity 311 as the third direction.

[0076] The first set of communication ports further includes a fifth communication port 365, which is arranged within the range of the included angle between the reverse of the third direction and the second direction, and its setting height in the first direction is slightly lower than that of the second communication port 362. The height of the fifth communication port 365 is set such that the fifth communication port 365 can cooperate with the fourth valve body 138. In other words, when the fourth valve body 138 rotates, the fifth communication port 365 can be selectively connected or disconnected. In addition, the fifth communication port 365 is arranged around the third cut cylindrical cavity 313 with the central axis O of the third cut cylindrical cavity 313 as the third direction.

[0077] Around each of the first communication port 361, the second communication port 362, the third communication port 363, the fourth communication port 364, and the fifth communication port 365, there is a pipe extending outward from the housing body 202, so that each communication port can be connected to other devices or pipes through the pipes.

[0078] Figure 3G Yes Figure 2 The sectional view of the housing body 202 shown along Figure 3D the D-D section line in the figure is shown to illustrate the specific arrangement of the sixth communication port 366 and its pipe. As Figure 3G shown, the first set of communication ports further includes a sixth communication port 366, which is arranged at the junction of the cavity wall of the first cut cylindrical cavity 311 and the cavity wall of the second cut cylindrical cavity 312. The sixth communication port 366 is arranged within the range of the included angle between the reverse of the third direction and the second direction, and its setting height in the first direction is slightly lower than that of the second communication port 362. The height of the sixth communication port 366 is set such that the sixth communication port 366 can cooperate with the second valve body 134. In other words, when the second valve body 134 rotates, the sixth communication port 366 can be selectively connected or disconnected.

[0079] Combined Figure 2 seen, the pipe 370 is arranged around the sixth communication port 366 and extends outward from the housing body 202. The pipe orifice 375 of the pipe 370 is blocked by the cover 203 so that fluid cannot flow into or out of the housing body 202 from the pipe orifice 375. The housing body 202 further includes a pipe 371 perpendicular to the pipe 370. The pipe 371 is in fluid communication with the pipe 370. In this way, the fluid flowing out of or into the housing body 202 from the sixth communication port 366 can flow through the pipe orifices 373, 374 of the pipe 371.

[0080] Continuing to refer to FIGS. 3A - 3E, a second set of flow ports is provided on the cavity wall of the second cavity 114. The second set of flow ports includes a seventh communication port 367 and an eighth communication port 368. The seventh communication port 367 is arranged within the range of the angle between the second direction and the third direction, and its setting in the first direction is higher than that of the fourth flow port 364. The eighth communication port 368 is arranged within the range of the angle between the reverse of the third direction and the second direction, and its setting height in the first direction is slightly lower than that of the seventh communication port 367. The heights of the seventh communication port 367 and the eighth communication port 368 are set such that the seventh communication port 367 and the eighth communication port 368 can cooperate with the third valve body 136. In other words, when the third valve body 136 rotates, the seventh communication port 367 and / or the eighth communication port 368 can be selectively connected or disconnected.

[0081] Each of the seventh communication port 367 and the eighth communication port 368 has a pipe disposed around it and extending outward from the housing body 202, so that each flow port can be connected to other devices or pipes through the pipe.

[0082] The second set of flow ports further includes a pump outlet communication port 369. The pump outlet communication port 369 is provided on the vertical partition plate 324 and is used to connect to a pump outlet (not shown). Specifically, the pump outlet communication port 369 is arranged within the range of the angle between the reverse of the second direction and the reverse of the third direction, and the height of the pump outlet communication port 369 is set such that the pump outlet communication port 369 can cooperate with the third valve body 136. In other words, when the third valve body 136 rotates, the pump outlet communication port 369 can be selectively connected or disconnected.

[0083] As an example, the regulating valve 100 in the present application uses a pump (not shown) as the power source for fluid flow. As Figure 3A shown, a plurality of through holes 342 are provided on the second transverse partition plate 323 at the top of the first cavity 112 for connecting to the inlet of the pump. The opening 399 at the top of the second cavity 114 can be covered by the pump. In this way, the fluid in the first cavity 112 can flow out of the housing 101 through the plurality of through holes 342 and then enter the pump, and the fluid flowing out through the pump outlet can enter the second cavity 114 through the pump outlet communication port 369.

[0084] As an example, an actuator (not shown) is used as the power source for driving the rotation of the drive shaft 118 in the present application. As Figure 3B shown, a circular hole 303 is provided at the bottom of the first cavity 112 for arranging the actuator. Through the hole 303, the actuator can be connected to the drive shaft 118 to drive the drive shaft 118 to rotate.

[0085] Figure 4A is Figure 1BA perspective view of the drive shaft 118 shown from above from an angle; Figure 4B is Figure 1B A perspective view of the drive shaft shown from below from another angle. As Figure 4A and 4B shown, the drive shaft 118 includes a shaft rod 401. The upper end 410 of the shaft rod 401 is designed to be able to match the concave portion 394 in the housing body 202, so that the shaft rod 401 can be rotatably connected to the housing 101. The lower end 412 of the shaft rod 401 is designed to be able to match the output end of the actuator, so that when the actuator operates, it can drive the drive shaft 118 to rotate.

[0086] The regulating valve 100 further includes a first separable drive structure 402, a second separable drive structure 403, and a third separable drive structure 404 provided on the shaft rod 401. Specifically, the first separable drive structure 402 is provided at the upper part of the shaft rod 401. The first separable drive structure 402 includes a first transverse plate 422 and a plurality of first rods 424, 426, 428. The first transverse plate 422 is generally fan-shaped and is horizontally provided at the upper part of the shaft rod 401 so that the circumferential direction of the fan shape is consistent with the circumferential direction of the shaft rod 401. The center of the fan coincides with the axis of the shaft rod 401, so that when the drive shaft 118 rotates about the first axis X, the plurality of first rods 424, 426, 428 on the first transverse plate 422 can also rotate about the first axis X. The plurality of first rods 424, 426, 428 are uniformly arranged along the circumferential direction of the first transverse plate 422 near the outer edge of the first transverse plate 422 and extend downward from the bottom surface of the first transverse plate 422. The plurality of first rods 424, 426, 428 are arranged to be able to cooperate with the first separable driven structure 555 on the first valve body 132, so that when the drive shaft 118 rotates within the first angular range, the first separable drive structure 402 on the drive shaft 118 (i.e., at least one of the plurality of first rods 424, 426, 428) can drive the first valve body 132 to rotate together.

[0087] The second separable drive structure 403 includes a second transverse arm 432 and a second rod 433. The second transverse arm 432 is generally elongated and perpendicularly extends from the shaft 401 in the radial direction of the shaft 401, so that when the shaft 401 rotates, the distal end 436 of the second transverse arm 432 can also perform a circular motion. The second rod 433 is disposed at the distal end 436 of the second transverse arm 432 and extends upward from the upper surface of the second transverse arm 432. The second rod 433 is configured to cooperate with the second separable driven structure 755 on the second valve body 134, so that when the drive shaft 118 rotates within the second angular range, the second separable drive structure 403 (i.e., the second rod 433) on the drive shaft 118 can drive the second valve body 134 to rotate together.

[0088] The third separable drive structure 404 includes a third transverse arm 442 and a third rod 443. The third transverse arm 442 is generally elongated and perpendicularly extends from the upper part of the shaft 401 in the radial direction of the shaft 401, so that when the shaft 401 rotates, the distal end 446 of the third transverse arm 442 can also perform a circular motion. The third rod 443 is disposed at the distal end 446 of the third transverse arm 442 and extends downward from the lower surface of the third transverse arm 442. The third rod 443 is configured to cooperate with the third separable driven structure 955 on the third valve body 136 and the fourth separable driven structure 1155 on the fourth valve body 138, so that when the drive shaft 118 rotates within the third angular range, the third separable drive structure 404 (i.e., the third rod 443) on the drive shaft 118 can drive the third valve body 136 to rotate; and when the drive shaft 118 rotates within the fourth angular range, the third separable drive structure 404 (i.e., the third rod 443) on the drive shaft 118 can drive the fourth valve body 138 to rotate.

[0089] Figure 5A is Figure 1B a perspective view of the first valve body 132 shown looking down from above; Figure 5B is Figure 1B a perspective view of the first valve body 132 shown looking up from below. As Figure 5A and 5B shown, the first valve body 132 is generally a sphere cut vertically up and down, and it has a rotating shaft 162. A concave portion 552 is provided at the lower part of the rotating shaft 162, thereby forming a sleeve 155. The sleeve 155 is used to receive the upper end of the rotating shaft 164 of the second valve body 134, so that the first valve body 132 and the second valve body 134 can rotate about the same first axis X. The upper part 502 of the first valve body 132 is designed to match the concave portion 393 of the second transverse partition plate 323, so that the upper part 502 of the first valve body 132 can be received by the concave portion 393.

[0090] A first detachable driven structure 555 is provided on the sphere of the first valve body 132. The first detachable driven structure 555 includes a plurality of first grooves 512, 513, 514, 515, 516, 517. The plurality of first grooves 512, 513, 514, 515, 516, 517 are provided on the upper surface of the sphere of the first valve body 132 and are arranged along the circumference of the first valve body 132. Specifically, the plurality of first grooves 512, 513, 514, 515, 516, 517 are formed by slotting from the edge of the sphere of the first valve body 132 to the inside of the sphere, and the distribution of the plurality of first grooves 512, 513, 514, 515, 516, 517 on the sphere of the first valve body 132 forms a central angle β.

[0091] The first valve body 132 is provided with two openings 562, 564, and the two openings 562, 564 are configured so that when the first valve body 132 rotates, at least one of the two openings 562, 564 can selectively align with the first flow port 361 and / or the second flow port 362 on the cavity wall of the first cavity 112, thereby realizing the flow and disconnection of the first flow port 361 and the second flow port 362 respectively.

[0092] Figure 6 1 is a schematic diagram of the matching relationship between the first valve body 132 and the drive shaft 118, which exemplarily shows one state in which the first detachable driving structure 402 is engaged with the first detachable driven structure 555. Figure 6 As shown, when the drive shaft 118 rotates within the first angle range, at least one of the plurality of first rods 424, 426, 428 on the drive shaft 118 can engage with at least one of the plurality of first grooves 512, 513, 514, 515, 516, 517. Thus, the drive shaft 118 can drive the first valve body 132 to rotate.

[0093] It should be noted that, although the first valve body 132 is sleeved on the second valve body 134 , due to the friction between the first valve body 132 and the second valve body 134 , when the first valve body 132 rotates, the second valve body 134 does not rotate with the first valve body 132 .

[0094] Figure 7A yes Figure 1B A perspective view of the second valve body 134 as viewed from above; Figure 7B yes Figure 1B The second valve body 134 is shown in a three-dimensional view from bottom to top. Figure 7A and 7BAs shown, the second valve body 134 includes a second valve body 733 and a rotating shaft 164. The top of the rotating shaft 164 is stepped and can be received by the sleeve 155 at the lower part of the first valve body 132, so that the first valve body 132 and the second valve body 134 can rotate around the same first axis X.

[0095] The second valve body 733 is generally a spherical shell cut at the top and bottom, and the second valve body 733 is arranged around the rotating shaft 164. The lower part of the second valve body 733 is fixedly connected to the rotating shaft 164 through a plurality of connecting columns 704, 706, 708. The second valve body 733 is provided with an opening 762, and the opening 762 is configured so that when the second valve body 134 rotates, the opening 762 can be selectively aligned with the third flow port 363 and / or the sixth communication port 366 on the cavity wall of the first cavity 112, thereby realizing the flow and disconnection of the third flow port 363 and the sixth communication port 366.

[0096] A second detachable driven structure 755 is provided at the lower portion of the rotating shaft 164. The second detachable driven structure 755 includes a second valve body plate 712. One end of the second valve body plate 712 is connected to the lower portion of the rotating shaft 164, and a second groove 722 is provided on the other end of the second valve body plate 712. The second groove 722 is arranged along the radial direction of the second valve body 134. When the driving shaft 118 rotates within the second angle range, the second rod 433 on the driving shaft 118 can engage with the second groove 722 on the second valve body 134.

[0097] Figure 8 1 is a schematic diagram of the matching relationship between the second valve body 134 and the drive shaft 118, which exemplarily shows one state of the second detachable driving structure 403 and the second detachable driven structure 755 being engaged. Figure 8 As shown, when the driving shaft 118 rotates within the second angle range, the second rod 433 on the driving shaft 118 engages with the second groove 722. Thus, the driving shaft 118 can drive the second valve body 134 to rotate within the second angle range.

[0098] It should be noted that although the first valve body 132 is sleeved on the second valve body 134 , due to the friction between the first valve body 132 and the second valve body 134 , when the second valve body 134 rotates, the first valve body 132 does not rotate with the rotation of the second valve body 134 .

[0099] Figure 9A yes Figure 1B A perspective view of the third valve body 136 as viewed from above from one angle; Figure 9B yes Figure 1B The third valve body 136 is shown in a three-dimensional view from another angle looking upward from the bottom. Figure 9A and 9BAs shown, the third valve body 136 includes a third valve body main body 933 and a rotating shaft 166. The top of the rotating shaft 166 is received by the connecting portion on the pump, and the lower portion of the rotating shaft 166 is provided with a recess 902, thereby forming a sleeve 156. The sleeve 156 is used to receive the upper end of the rotating shaft 168 of the fourth valve body 138, so that the third valve body 136 and the fourth valve body 138 can rotate around the same second axis Y.

[0100] The third valve body 933 is roughly spherical and is arranged around the rotating shaft 166. The lower part of the third valve body 933 is fixedly connected to the rotating shaft 166 through the connecting plate 904. The third valve body 933 is provided with two openings 962, 964, and the two openings 962, 964 are configured so that when the third valve body 136 rotates, at least one of the two openings 962, 964 can selectively align with the pump outlet communication port 369, the seventh communication port 367 and / or the eighth communication port 368 on the cavity wall of the second cavity 114, so as to realize the flow and disconnection of the pump outlet communication port 369, the seventh communication port 367 and the eighth communication port 368.

[0101] A third detachable driven structure 955 is provided at the lower portion of the rotating shaft 166. The third detachable driven structure 955 includes a third valve body plate 912. One end of the third valve body plate 912 is connected to the lower portion of the rotating shaft 166, and a third groove 922 is provided on the other end of the third valve body plate 912. The third groove 922 is arranged along the radial direction of the third valve body 136. When the driving shaft 118 rotates within the third angle range, the third rod 443 on the driving shaft 118 can engage with the third groove 922 on the third valve body 136.

[0102] Figure 10 1 is a schematic diagram of the matching relationship between the third valve body 136 and the drive shaft 118, which exemplarily shows one state of the third detachable driving structure 404 and the third detachable driven structure 955 being engaged. Figure 10 As shown, when the drive shaft 118 rotates within the third angle range, the third rod 443 on the drive shaft 118 engages with the third groove 922 on the third valve body 136. Thus, the drive shaft 118 can drive the third valve body 136 to rotate within the third angle range.

[0103] It should be noted that although the third valve body 136 is sleeved on the fourth valve body 138 , due to the friction between the third valve body 136 and the fourth valve body 138 , when the third valve body 136 rotates, the fourth valve body 138 does not rotate with the rotation of the second valve body 134 .

[0104] Figure 11A yes Figure 1B A perspective view of the fourth valve body 138 as viewed from above from one angle; Figure 11B yes Figure 1BThe fourth valve body 138 is shown in FIG. 1 , which is a three-dimensional view from another angle looking upward from the bottom. Figure 11A and 11B As shown, the fourth valve body 138 includes a fourth valve body 1133 and a rotating shaft 168. The top of the rotating shaft 166 is stepped, which can be received by the sleeve 156 at the bottom of the third valve body 136, so that the third valve body 136 and the fourth valve body 138 can rotate around the same second axis Y.

[0105] The fourth valve body 1133 is generally spherical and is disposed around the rotating shaft 168. The upper and lower parts of the fourth valve body 1133 are respectively provided with connecting plates 1104 and 1105 fixedly connected to the rotating shaft 168. The fourth valve body 1133 is provided with three openings 1162, 1164, and 1166, and the three openings 1162, 1164, and 1166 are configured so that when the fourth valve body 138 rotates, at least one of the three openings 1162, 1164, and 1166 can be selectively aligned with the fourth flow port 364 on the cavity wall of the first cavity 112, thereby realizing the flow and disconnection of the fourth flow port 364.

[0106] A fourth detachable driven structure 1155 is provided on the upper portion of the rotating shaft 168. The fourth detachable driven structure 1155 includes a fourth valve body plate 1112. One end of the fourth valve body plate 1112 is connected to the upper portion of the rotating shaft 168, and a fourth groove 1122 is provided on the other end of the fourth valve body plate 1112. The fourth groove 1122 is arranged along the radial direction of the fourth valve body 138. When the driving shaft 118 rotates within the fourth angle range, the third rod 443 on the driving shaft 118 can engage with the fourth groove 1122 on the fourth valve body 138.

[0107] Figure 12 1 is a schematic diagram of the matching relationship between the fourth valve body 138 and the drive shaft 118, which exemplarily shows one state of the third detachable driving structure 404 and the fourth detachable driven structure 1155 being engaged. Figure 12 As shown, when the driving shaft 118 rotates within the fourth angle range, the third rod 443 on the driving shaft 118 engages with the fourth groove 1122. Thus, the driving shaft 118 can drive the fourth valve body 138 to rotate within the fourth angle range.

[0108] It should be noted that although the third valve body 136 is sleeved on the fourth valve body 138 , due to the friction between the third valve body 136 and the fourth valve body 138 , when the fourth valve body 138 rotates, the third valve body 136 does not rotate with the rotation of the fourth valve body 138 .

[0109] It should also be noted that, in the embodiments of the present application, the third clutchable driven structure 955 and the fourth clutchable driven structure 1155 are respectively engaged with the third clutchable driving structure 404 to form a third clutch structure and a fourth clutch structure. However, since the lengths of the groove walls on both sides of the third groove 922 are different from the lengths of the groove walls at both ends of the fourth groove 1122, the engagement and separation times of the third clutch structure and the fourth clutch structure are also different. In the embodiments of the present application, when the drive shaft 118 rotates within the third angular range, the third clutch structure can be engaged, and when the drive shaft 118 rotates within the fourth angular range, the fourth clutch structure can be engaged.

[0110] Since the first clutch structure, the second clutch structure, the third clutch structure, and the fourth clutch structure in the present application generally use the method of grooves and rods to achieve clutch engagement and separation, for the sake of clearly explaining the specific cooperation relationship in the clutch structure, the third clutch structure is taken as an example in the present application for detailed explanation.

[0111] Figure 13A - 13H It is a schematic diagram of the third clutch structure during operation, used to show how the third clutch structure achieves engagement and separation. Specifically, the third clutch structure includes a third clutchable driving structure 404 and a third clutchable driven structure 955. When the drive shaft 118 rotates within the third angular range, the third clutchable driving structure 404 can be engaged with the third clutchable driven structure 955, thereby driving the third clutchable driven structure 955 to rotate together; when the drive shaft 118 rotates outside the third angular range, the third clutchable driving structure 404 is separated from the third clutchable driven structure 955, so as not to drive the third clutchable driven structure 955 to rotate. Figure 13A - 13H The relative positional relationship between the shaft rod 401 of the drive shaft 118, the third transverse arm 442, and the third rod 443 is schematically shown. When the drive shaft 118 rotates, the shaft rod 401, the third transverse arm 442, and the third rod 443 rotate together around the third axis Z. Figure 13A - 13H The relative positional relationship between the rotating shaft 166 of the third valve body 136, the third valve body plate 912, and the third groove 922 is also schematically shown. When the third valve body 136 rotates, the rotating shaft 166, the third valve body plate 912, and the third groove 922 rotate together around the second axis Y.

[0112] Figure 13A It shows the relative positional relationship between the third clutchable driving structure 404 and the third clutchable driven structure 955 when the drive shaft 118 has not yet rotated to the initial angle of the third angular range. Specifically, the actuator drives the drive shaft 118 in the counterclockwise direction (for example, as Figure 13Arotates in the direction of arrow T in [description], so the third clutchable drive structure 404 also rotates counterclockwise. Since the third clutchable driven structure 955 is not driven by an actuator, it stays at the first position.

[0113] Figure 13B Shows the relative position relationship between the third clutchable drive structure 404 and the third clutchable driven structure 955 when the drive shaft 118 rotates to the first boundary angle of the third angle range. Specifically, when the drive shaft 118 rotates counterclockwise to the initial angle of the third angle range, the third rod 443 of the drive shaft 118 contacts the first side wall 1302 of the third groove 922, so the third rod 443 is received in the third groove 922.

[0114] Figure 13C Shows the relative position relationship between the third clutchable drive structure 404 and the third clutchable driven structure 955 when the drive shaft 118 rotates counterclockwise within the third angle range. Specifically, when the drive shaft 118 continues to rotate counterclockwise, the third rod 443 pushes the first side wall 1302 of the third groove 922, causing the third valve body plate 912 to rotate. Thus, the third clutchable drive structure 404 drives the third clutchable driven structure 955 to rotate in the clockwise direction (e.g., in the direction of arrow U in [description]). Figure 13C in the direction of arrow U in [description]).

[0115] Figure 13D Shows that when the drive shaft 118 rotates to the second boundary angle of the third angle range, the third clutchable drive structure 404 is separated from the third clutchable driven structure 955. Figure 13E Shows that when the drive shaft 118 rotates outside the third angle range, the third clutchable drive structure 404 is separated from the third clutchable driven structure 955. Specifically, when the drive shaft 118 continues to rotate counterclockwise, the third rod 443 disengages from the third groove 922, so that while the drive shaft 118 continues to rotate counterclockwise, the third clutchable driven structure 955 remains at the second position. That is to say, at this time, the third clutchable drive structure 404 cannot drive the third clutchable driven structure 955 to rotate.

[0116] Figure 13F Shows the relative position relationship between the third clutchable drive structure 404 and the third clutchable driven structure 955 when the drive shaft 118 rotates to the second boundary angle of the third angle range. Specifically, when the drive shaft 118 rotates in the clockwise direction (e.g., in the direction of arrow P in [description]), the third clutchable drive structure 404 also rotates clockwise. The third rod 443 of the drive shaft 118 contacts the second side wall 1304 of the third groove 922, so the third rod 443 is received in the third groove 922. Figure 13F in the direction of arrow P in [description]).

[0117] Figure 13G It shows the relative positional relationship between the third clutchable driving structure 404 and the third clutchable driven structure 955 when the drive shaft 118 rotates clockwise within the third angular range. Specifically, when the drive shaft 118 continues to rotate in the clockwise direction, the third rod 443 pushes the second side wall 1304 of the third groove 922, thereby causing the third valve body plate 912 to rotate. Thus, the third clutchable driving structure 404 drives the third clutchable driven structure 955 to rotate counterclockwise (e.g., in the direction of arrow V as shown in Figure 13G ).

[0118] Figure 13H It shows that when the drive shaft 118 rotates to the first boundary angle of the third angular range, the third clutchable driving structure 404 is separated from the third clutchable driven structure 955. Specifically, when the drive shaft 118 continues to rotate in the clockwise direction, the third rod 443 disengages from the third groove 922, so that while the drive shaft 118 continues to rotate clockwise or counterclockwise, the third clutchable driven structure 955 remains in the first position. That is to say, at this time, the third clutchable driving structure 404 cannot drive the third clutchable driven structure 955 to rotate.

[0119] It should be noted that the angle at which the rotation of the third clutchable driving structure 404 can engage with the third clutchable driven structure 955 to drive the third clutchable driven structure 955 to rotate is called the third angular range.

[0120] Continue to refer to Figure 4A - 4B . It can be seen from the figure that the first clutchable driving structure 402, the second clutchable driving structure 403, and the third clutchable driving structure 404 provided on the shaft rod 401 are arranged in different angular directions along the shaft rod 401. Such an arrangement can enable the clutchable driving structures on the shaft rod 401 to selectively engage with the clutchable driven structures on the valve body when the shaft rod 401 rotates by different angles, thereby driving the rotation of different valve bodies.

[0121] In the present application, the specific structures and positional relationships of the first valve body 132, the second valve body 134, the third valve body 136, the fourth valve body 138, and the first clutch structure, the second clutch structure, the third clutch structure, and the fourth clutch structure are configured to enable: the opening on the first valve body 132 to cooperate with the first flow port 361 and the second flow port 362, so that the opening on the first valve body 132 can selectively open at least one of the first flow port 361 and the second flow port 362; the opening on the second valve body 134 to cooperate with the third flow port 363 and the sixth flow port 366, so that the opening on the second valve body 134 can selectively open at least one of the third flow port 363 and the sixth flow port 366; the opening on the third valve body 136 to cooperate with the seventh flow port 367 and the eighth flow port 368, so that the opening on the third valve body 136 can selectively open at least one of the seventh flow port 367 and the eighth flow port 368; the opening on the fourth valve body 138 to cooperate with the fifth flow port 365, so that the opening on the fourth valve body 138 can selectively open the fifth flow port 365.

[0122] When the drive shaft 118 rotates, one or more of the first valve body 132, the second valve body 134, the third valve body 136, and the fourth valve body 138 can be selectively rotated, thereby forming different flow channels inside the regulating valve 100. As an example, the regulating valve 100 can achieve various communication relationships as shown in Table 1.

[0123]

[0124] Table 1

[0125] The left serial numbers 1 - 10 in Table 1 represent different angles of rotation of the drive shaft 118. For example, serial number 1 represents the drive shaft 118 rotating at the first angle. It should be noted that, as an example, serial numbers 1 - 10 represent the angles of rotation of the drive shaft 118 from an initial angle in the same direction. It should also be noted that the drive shaft 118 is configured to be able to rotate bidirectionally (i.e., clockwise rotation and counterclockwise rotation).

[0126] The symbol "O" in Table 1 indicates that the communication port is in a fully connected state, that is, the flow port on the housing is aligned with the opening on the valve body, so that the fluid can flow through the entire area of the flow port on the housing. The symbol "R" in Table 1 indicates that the communication port is in a partially connected state, that is, the flow port on the housing is partially aligned with the opening on the valve body, so that the fluid can only flow through the part where the flow port is aligned with the valve body opening. The symbol "×" in Table 1 indicates that the flow port is in a disconnected state, that is, the flow port is blocked by the valve body itself, so that the fluid cannot flow through this flow port. It should be noted that "connection" in the present application includes the fully connected state and the partially connected state.

[0127] By controlling the opening and closing states of the flow ports on each housing and the mutual cooperation between the valve bodies, several flow channels can be formed in the regulating valve 100. Each flow channel is used to connect two corresponding flow ports, so that the external pipelines connected to these two corresponding flow ports can be connected through this flow channel. The several flow channels in the regulating valve 100 can be turned on or off by controlling the rotation of each valve body. For example, if the fourth flow port 364 listed in Table 1 is used as the fluid inlet of the regulating valve 100 and the remaining seven flow ports are used as the fluid outlets of the regulating valve 100, then there are seven flow channels in the regulating valve 100, including flow channel 1, flow channel 2, flow channel 3, flow channel 5, flow channel 6, flow channel 7, and flow channel 8. Among them, flow channel 1 connects the fourth flow port 364 and the first flow port 361, flow channel 2 connects the fourth flow port 364 and the second flow port 362, flow channel 3 connects the fourth flow port 364 and the third flow port 363, flow channel 5 connects the fourth flow port 364 and the fifth flow port 365, flow channel 6 connects the fourth flow port 364 and the sixth flow port 366, flow channel 7 connects the fourth flow port 364 and the seventh flow port 367, and flow channel 8 connects the fourth flow port 364 and the eighth flow port 368.

[0128] When the regulating valve 100 is at the first angle, the opening on the first valve body 132 is aligned with the first flow port 361, so that the first flow port 361 is opened; the opening on the first valve body 132 is aligned with the second flow port 362, so that the second flow port 362 is opened; the opening on the second valve body 134 is aligned with the third flow port 363, so that the third flow port 363 is opened; the opening on the fourth valve body 138 is aligned with the fifth flow port 365, so that the fifth flow port 365 is opened; the opening on the third valve body 136 is aligned with the seventh flow port 367, so that the seventh flow port 367 is opened; the opening on the third valve body 136 is aligned with the eighth flow port 368, so that the eighth flow port 368 is opened; and the opening on the second valve body 134 is not aligned with the sixth flow port 366, so that the sixth flow port 366 is closed or blocked. At this time, flow channel 1 connecting the fourth flow port 364 and the first flow port 361 is turned on, flow channel 2 connecting the fourth flow port 364 and the second flow port 362 is turned on, flow channel 3 connecting the fourth flow port 364 and the third flow port 363 is turned on, flow channel 5 connecting the fourth flow port 364 and the fifth flow port 365 is turned on, flow channel 7 connecting the fourth flow port 364 and the seventh flow port 367 is turned on, flow channel 8 connecting the fourth flow port 364 and the eighth flow port 368 is turned on, and flow channel 6 connecting the fourth flow port 364 and the sixth flow port 366 is turned off.

[0129] When the control valve 100 is at the second angle, the opening on the first valve body 132 is aligned with the first flow port 361, so that the first flow port 361 is opened; the opening on the first valve body 132 is aligned with the second flow port 362, so that the second flow port 362 is opened; the opening on the second valve body 134 is aligned with the third flow port 363, so that the third flow port 363 is opened; the opening on the fourth valve body 138 is aligned with the fifth flow port 365, so that the fifth flow port 365 is opened; the opening on the second valve body 134 is aligned with the sixth flow port 366, so that the sixth flow port 366 is opened; the opening on the third valve body 136 is aligned with the seventh flow port 367, so that the seventh flow port 367 is opened; the opening on the third valve body 136 is aligned with the eighth flow port 368, so that the eighth flow port 368 is opened. At this time, the flow channel 1 connecting the fourth flow port 364 and the first flow port 361 is connected, the flow channel 2 connecting the fourth flow port 364 and the second flow port 362 is connected, the flow channel 3 connecting the fourth flow port 364 and the third flow port 363 is connected, the flow channel 5 connecting the fourth flow port 364 and the fifth flow port 365 is connected, the flow channel 6 connecting the fourth flow port 364 and the sixth flow port 366 is connected, the flow channel 7 connecting the fourth flow port 364 and the seventh flow port 367 is connected, and the flow channel 8 connecting the fourth flow port 364 and the eighth flow port 368 is connected.

[0130] Similarly, when the control valve 100 is at the third to tenth angles, the on-off states of the respective flow channels in the control valve 100 can be obtained according to Table 1.

[0131] It should be noted that Figure 1A - Figure 14 the control valve 100 in the illustrated embodiment is not limited to the above applications. According to the needs of the cooling path of the cooling system, various different flow channels can be formed in the control valve 100 by configuring power devices such as pumps, so that the control valve 100 can be used as a switching device for the cooling path to achieve the purpose of switching the cooling path.

[0132] Although the slot and the rod are used as an example to describe the clutch structure in this application, those skilled in the art can understand that according to the spirit of this application, other cooperation methods for realizing this clutch and separation (such as a clamping device, gear meshing) are also within the protection scope of this application. The control valve 100 of this application can realize the switching of different fluid channels through the settings of the openings on the valve body and the flow ports on the housing, and can also control the flow rates of the respective channels. Such a setting enables the control components in the system to control fewer components to achieve the switching of different fluid channels, and can enhance the stability of system control while achieving integrated control.

[0133] To ensure the sealing performance between the flow ports and the valve body when each flow port in the control valve 100 is not aligned with the opening on the valve body (i.e., the flow port is closed), the control valve 100 further includes a first set of seals and a second set of seals. Each of the first set of seals is disposed between the first valve body 132, the second valve body 134, the fourth valve body 138 and each of the first set of flow ports. Each of the first set of seals is configured to be able to resist against the cavity wall where each of the first set of flow ports is located, so that when the valve body rotates, the first set of seals can abut against the cavity wall and will not rotate along with the rotation of the valve body. The second set of seals includes two seals. One of the two seals is disposed between the seventh communication port 367 and the third valve body 136, and the other of the two seals is disposed between the eighth communication port 368 and the third valve body 136. Since the pump outlet communication port 369 in the second set of flow ports is connected to the outlet of the pump, no sealing ring is provided.

[0134] When the valve body rotates, due to the friction between the valve body and the seals, the actuator driving the valve body to rotate requires a large driving force to drive the valve body to rotate so as to overcome the frictional force between the valve body and the seals. When a conventional control valve drives one or more valve bodies to rotate, the drive shaft of the control valve needs to overcome the frictional forces brought by all the seals provided in the valve body, resulting in a relatively large required power for the actuator. However, in the control valve 100 of the present application, the drive shaft 118 in the drive mechanism selectively engages the drive structure and the driven structure at the same time, and the drive structure can drive the driven structure to rotate, so that the drive shaft 118 drives the driven component (i.e., at least one of the first valve body 132, the second valve body 134, the third valve body 136 and the fourth valve body 138) to rotate.

[0135] The control valve 100 in the present application further has the following advantages: when the passage that needs to be in communication in the control valve 100 can be achieved by the rotation of the valve body on one side of the drive shaft 118, since the valve body on the other side does not rotate, no frictional force will be generated between the non-rotating valve body and the seals, thereby reducing the driving force provided by the actuator, and only the frictional force that the valve body that the drive shaft 118 needs to rotate needs to overcome needs to be provided. The following takes the states of the valve bodies in the control valve 100 at serial numbers 8-10 in Table 1 as an example for introduction.

[0136] Figure 14 Yes Figure 1A Schematic diagram of the control valve 100 shown in which the first flow port 361 and the second flow port 362 are sectioned along the horizontal direction, Figure 14The first seal 1402 disposed between the first valve body 132 and the first flow port 361, the second seal 1404 disposed between the first valve body 132 and the second flow port 362, and the third seal 1406 disposed between the fourth valve body 138 and the fifth flow port 365 are shown. When the drive shaft 118 rotates within the angular range shown in Nos. 8-10, only the first valve body 132 and the second valve body 134 need to be rotated. Therefore, the actuator that drives the drive shaft 118 to rotate only needs to provide a force that can overcome the frictional force of the seals on the first valve body 132 and the second valve body 134.

[0137] Therefore, when the driving force of the actuator is constant, the regulating valve provided in the present application is particularly suitable for applications that provide a relatively large number of flow channels. Because the drive shaft of the regulating valve in the present application only needs to overcome the frictional force generated by the seal between the driven valve body and the housing, rather than having to overcome the frictional forces generated by all the seals between the valve bodies and the housing at the same time. Therefore, it is not necessary to increase the output power of the actuator 190 as the number of flow channels in the valve increases.

[0138] Although only some features of the present application are illustrated and described herein, various improvements and changes can be made by those skilled in the art. Therefore, it should be understood that the appended claims are intended to cover all such improvements and changes that fall within the spirit of the present application.
