DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0009] The present invention will now be described in detail, and in order to make the objects and advantages of the present invention more comprehensible, the present invention will be further described in detail with reference to the following drawings and examples. In this specification, relational terms such as "first" and "second" do not require or imply that any such actual relationship or order exists between those elements, but rather are used merely to distinguish between two elements having the same name.

[0010] As shown in FIGS. 1 to 4, an embodiment of the present invention provides a control valve 1, which includes a drive unit 100, an upper cover 66, a valve body 61, a first valve element 62 and a second valve element 63. At least a portion of the first valve body 62 and at least a portion of the second valve body 63 are located within the valve body 61, and the first valve body 62 and the second valve body 63 can both be rotated individually by being driven. As a result, the communicating chambers of the two valve bodies communicate with the valve ports of the different control valves 1, thereby achieving the control function of the control valve 1 with respect to the fluid. Furthermore, at least a portion of the first valve body 62 and at least a portion of the second valve body 63 are located between the top cover 66 and the valve body 61, and the space between the top cover 66 and the valve body 61 is arranged to provide a seal, preventing leakage of fluid. The drive device 100 is located on the side of the upper cover 66 away from the valve body 61, and is capable of rotating the first valve body 62 and the second valve body 63.

[0011] 1 to 4, the control valve 1 has a first chamber 611, a second chamber 612, and a communication hole path 613 that connects the first chamber 611 and the second chamber 612, and this communication hole path 613 enables mutual flow of fluids in the first chamber 611 and the second chamber 612, and the arrangement direction of the first chamber 611 and the second chamber 612 intersects with the height direction of the control valve 1; for example, in FIG. 1, the arrangement direction of the first chamber 611 and the second chamber 612 is perpendicular to the height direction of the control valve 1. Referring to FIG. 4, the valve body 61 includes a first side wall portion 614 and a second side wall portion 615 . The first side wall portion 614 and the second side wall portion 615 are fixedly connected and arranged to seal or are integrally molded, and the first side wall portion 614 is the peripheral wall or at least a part of the peripheral wall of the first chamber 611, and the second side wall portion 615 is the peripheral wall or at least a part of the peripheral wall of the second chamber 612. Referring to FIG. 4, the valve body 61 further includes a connecting wall portion 618 that connects the first side wall portion 614 and the second side wall portion 615 . This connecting wall portion 618 is located between the first side wall portion 614 and the second side wall portion 615, and is a peripheral wall or at least a part of the peripheral wall of the communicating hole passage 613, and the first side wall portion 614, the second side wall portion 615 and the connecting wall portion 618 can be integrally molded. In order to realize fluid flow, the control valve 1 has a first passage 616 and a second passage 617, one end of the first passage 616 penetrates the first side wall portion 614 to form a first communication port 6141, which is connected to the first chamber 611, and the other end of the first passage 616 penetrates the outer surface of the control valve 1 to form a first valve port. This allows fluid to enter and exit the control valve 1 through the first valve port, one end of the second passage 617 penetrates the second side wall portion 615 to form a second communication port 6151 which communicates with the second chamber 612, and the other end of the second passage 617 penetrates the outer surface of the control valve 1 to form a second valve port, allowing fluid to enter and exit the control valve 1 through the second valve port. In the control valve according to the embodiment of the present invention, by rotating the first valve body 62 and / or the second valve body 63, it is possible to realize a plurality of conduction modes between the plurality of first valve ports and between the first valve port and the second valve port, and also to realize the control function of the control valve 1 with respect to the fluid.

[0012] In order to rotate the first valve body 62 and the second valve body 63, as shown in Figs. 1 and 5, an embodiment of the present invention provides a driving device 100, which includes a housing 10 and a driving unit. The drive unit includes a first drive unit 20 and a second drive unit 30. The drive device 100 has an accommodating chamber 101, and the housing 10 includes a bottom wall portion 11 and a side wall portion 12 protruding from the bottom wall portion 11. The bottom wall portion 11 is a wall portion or at least a part of the wall portion of the storage chamber 101, and the side wall portion 12 is a peripheral wall portion or at least a part of the peripheral wall of the storage chamber 101, and along both ends of the longitudinal direction of the drive device 100, the main body of the orthogonal projection of the bottom wall portion 11 at both ends of the side wall portion 12 is arc-shaped. Compared with a rectangular orthogonal projection structure or other complex orthogonal projection structures, the driving device 100 according to the embodiment of the present invention has a smaller size. At least a portion of the first drive unit 20 and at least a portion of the second drive unit 30 are located within the accommodation chamber 101, the first drive unit 20 and the second drive unit 30 are arranged at a distance from each other and along the longitudinal direction of the drive device 100, and the first drive unit 20 includes a first motor 21. The first motor 21 includes a first body 211, a first power supply terminal 212, and a first output shaft 213, with the first power supply terminal 212 located at a first end in the longitudinal direction of the first body 211, and the first output shaft 213 located at a second end in the longitudinal direction of the first body 211, and the second drive unit 30 includes a second motor 31. The second motor 31 includes a second body 311, a second power supply terminal 312, and a second output shaft 313, with the second power supply terminal 312 located at a first end of the second body 311 in the longitudinal direction, the second output shaft 313 located at a second end of the second body 311 in the longitudinal direction, and the first end of the first body 211 and the first end of the second body 311 arranged adjacent to each other and located between the second end of the first body 211 and the second end of the second body 311. In a specific implementation, the first motor 21 includes two first power supply terminals 212, i.e., a positive power supply terminal and a negative power supply terminal, and the second motor 31 includes two second power supply terminals 312, i.e., a positive power supply terminal and a negative power supply terminal. The first power supply terminal 212 and the second power supply terminal 312 are disposed adjacent to each other and are located between the first body 211 and the second body 311 along the longitudinal direction of the drive device.

[0013] 5 to 9, the driving device 100 further includes a plurality of lead wire segments 401 for controlling the rotation of the first motor 21 and the second motor 31. As shown in FIG. The multiple lead wire segments 401 are electrically connected to correspond to the first power supply terminal 212 and the second power supply terminal 312. In the present invention, the electrical connection between the two components is such that an electrical signal can be transmitted between the two components, and the electrical connection between the two components may be achieved by direct contact, or the electrical connection may be achieved by another conductive component.

[0014] When specifically implemented, the driving device 100 further includes four lead wire segments 401, which are electrically connected to the two first power supply terminals 212 of the first motor 21 and the two second power supply terminals 312 of the second motor 31, respectively, so that electrical signals are transmitted to the corresponding power supply terminals via the lead wire segments 401. Each lead segment 401 includes a wire segment 402 . The wiring segment 402 is arranged adjacent to the bottom wall portion 11, and the extension direction of at least a portion thereof intersects with the longitudinal direction of the drive device 100, and in the multiple lead wire segments 401, the orthogonal projections of at least a portion of the wiring segments 402 at least partially overlap with the orthogonal projections of the first body 211 and / or the orthogonal projections of the second body 311, and in this case, the width of the gap between the first body 211 and the second body 311 along the longitudinal direction of the drive device 100 is smaller than the maximum width between the two wiring segments 402. For example, in FIG. 7 , the orthogonal projection of one wiring segment 402 electrically connected to the first power supply terminal 212 on the bottom wall portion 11 overlaps with the orthogonal projection of one wiring segment 402 electrically connected to the second power supply terminal 312 on the bottom wall portion 11 overlaps with the orthogonal projection of one wiring segment 402 electrically connected to the second power supply terminal 312 on the bottom wall portion 11 of the second body 311. Since the four wiring segments 402 are arranged side by side in the gap between the first body 211 and the second body 311, the size of the gap between the first body 211 and the second body 311 can be effectively reduced, thereby reducing the longitudinal size of the drive device, thereby achieving a miniaturized drive device.

[0015] 5 to 9, the drive device 100 includes a control member 50. As shown in FIG. The control member 50 and the drive unit are disposed with a gap therebetween and are arranged along the width direction of the drive device 100 , and each of the lead wire segments 401 is electrically connected to the control member 50 . 5, 8 and 9, the first driving unit 20 and the second driving unit 30 are located at one end of the width of the driving device 100, the control member 50 is located at the other end of the width of the driving device 100, the first power supply terminal 212 of the first motor 21 includes a first terminal T1 and a second terminal T2, one of the first terminal T1 and the second terminal T2 is a positive power supply terminal and the other is a negative power supply terminal, and the second power supply terminal 312 of the second motor 31 includes a third terminal T3 and a fourth terminal T4. One of the third terminal T3 and the fourth terminal T4 is a positive power supply terminal and the other is a negative power supply terminal. Along the width direction of the driving device 100, the first terminal T1 is located between the second terminal T2 and the control member 50, i.e., the first terminal T1 is closer to the control member 50 than the second terminal T2, and the third terminal T3 is located between the fourth terminal T4 and the control member 50. The multiple lead wire segments 401 of the driving device 100 include a first lead wire segment 41 electrically connected to the first terminal T1, a second lead wire segment 42 electrically connected to the second terminal T2, a third lead wire segment 43 electrically connected to the third terminal T3, and a fourth lead wire segment 44 electrically connected to the fourth terminal T4. 7, 9 and 10, at least a part of the wiring segments of the first lead wire segment 41 and at least a part of the wiring segments of the third lead wire segment 43 are embedded in the bottom wall portion 11, and the wiring segment 402 of the second lead wire segment 42 and the wiring segment 402 of the fourth lead wire segment 44 are embedded in the bottom wall portion 11 or protrude from the bottom wall portion 11 and positioned within the accommodation chamber 101. When projected onto the bottom wall portion 11 along the height direction of the drive device 100, The orthogonal projection of the first wiring segment 411 of the lead wire segment 41 at least partially overlaps with the orthogonal projection of the first body 211, the orthogonal projection of the third wiring segment 431 of the third lead wire segment 43 at least partially overlaps with the orthogonal projection of the second body 311, and the orthogonal projection of the second wiring segment 421 of the second lead wire segment 42 and the orthogonal projection of the fourth wiring segment 441 of the fourth lead wire segment 44 are located within the gap between the orthogonal projection of the first body 211 and the orthogonal projection of the second body 311.

[0016] Referring to FIG. 10, the wiring segment of the first lead wire segment 41 is defined as the first wiring segment 411, the wiring segment of the second lead wire segment 42 is defined as the second wiring segment 421, the wiring segment of the third lead wire segment 43 is defined as the third wiring segment 431, and the wiring segment of the fourth lead wire segment 44 is defined as the fourth wiring segment 441. The first wiring segment 411, the second wiring segment 421, the fourth wiring segment 441 and the third wiring segment 431 are arranged in order along the longitudinal direction of the driving device 100, and the pitch between two adjacent wiring segments 402 is 2.6 mm or more. The above arrangement reduces signal interference between adjacent lead segments and improves failures such as short circuits caused by condensation inside the drive.

[0017] Referring to Figures 5, 8 and 9, when projected onto the bottom wall portion 11 along the height direction of the drive device 100, the orthogonal projection of the first drive unit 20 and the orthogonal projection of the second drive unit 30 are arranged symmetrically with respect to an axis of symmetry M1 extending along the width direction of the drive device 100, and the structures of the first drive unit 20 and the second drive unit 30 are similar, and the first motor 21 includes a first output shaft 213 located at the second end of the first body 211, and the second motor 31 includes a second output shaft 313 located at the second end of the second body 311. The first driving unit 20 includes a first transmission gear set 22 that is transmission-connected to the first output shaft 213 by a worm, and the second driving unit 30 further includes a second transmission gear set 32 ​​. This second transmission gear group 32 is connected to the second output shaft 313 by a worm, and when projected onto the bottom wall portion 11 along the height direction of the drive unit 100, the orthogonal projection of the control member 50 at least partially overlaps with the orthogonal projection of the first transmission gear group 22 and the orthogonal projection of the second transmission gear group 32, respectively. With the above arrangement, the size of the drive device 100 in the width direction can be reduced.

[0018] As shown in FIGS. 8, 9 and 11, the first transmission gear group 22 includes a first output gear 223 and a first shaft 224 disposed coaxially with the first output gear 223. The first shaft 224 is located on the side of the first output gear 223 that is away from the bottom wall portion 11, and the second transmission gear group 32 includes a second output gear 323 and a second shaft 324 that is arranged coaxially with the second output gear 323. This second shaft 324 is located on the side of the second output gear 323 that is away from the bottom wall portion 11, and the first output gear 223 and the second output gear 323 are both located between the control member 50 and the bottom wall portion 11, and the first shaft 224 and the second shaft 324 both pass through the control member 50 and are arranged so as to be positionally limited relative to the control member 50, thereby achieving positional limitation of the control member 50.

[0019] 6 to 8, the control member 50 includes a control plate 51, and a first potentiometer 521 and a second potentiometer 522 fixedly connected to the control plate 51. The first potentiometer 521 and the second potentiometer 522 are located on the side of the control plate 51 away from the bottom wall portion 11, the first axis 224 passes through the control plate 51 and is fitted into the position limiting hole of the first potentiometer 521, and the second axis 324 passes through the control plate 51 and is fitted into the position limiting hole of the second potentiometer 522, and the cross-sections of the position limiting holes of the first potentiometer 521 and the second potentiometer 522 may be semicircular, and the cross-sections of the first axis 224 and the second axis 324 may also be semicircular. With the above arrangement, the rotating piece in the first potentiometer 521 and the first shaft 224 rotate synchronously, and the rotating piece in the second potentiometer 324 and the second potentiometer 522 rotate synchronously, to monitor the rotational status of the motor and valve body in the control valve. Compared to arranging a magnetic element on the worm and a Hall element on the control member, the first potentiometer 521 and the second potentiometer 522 of the embodiment of the present invention can simplify the structure of the drive device and reduce the size of the drive device.

[0020] As shown in FIGS. 11 and 12, the first transmission gear group 22 further includes a first input gear 221 and a first intermediate gear 222. The first input gear 221 is power-transmittingly connected to the first output shaft 213 by a worm gear, and the first output gear 223 is power-transmittingly connected to the first input gear 221 by a first intermediate gear 222. The center distance between the first input gear 221 and the first intermediate gear 222 is defined as d1, and the center distance between the first output gear 223 and the first intermediate gear 222 is defined as d2. The second transmission gear group 32 further includes a second input gear 321 and a second intermediate gear 322. The second input gear 321 is drivably connected to the second output shaft 313, and the second output gear 323 is drivably connected to the second input gear 321 by the second intermediate gear 322. The center distance between the second input gear 321 and the second intermediate gear 322 is defined as d3, the center distance between the second output gear 323 and the second intermediate gear 322 is defined as d4, and the center distance between the first output gear 223 and the second output gear 323 is defined as d5, and preferably, d1 is 13.5 mm, d2 is 17.5 mm, d3 is 13.5 mm, d4 is 17.5 mm, and d5 is 66 mm or less. With the above arrangement, the transmission gear group can stably transmit torque and shorten the center distance between the first output gear 223 and the second output gear 323, thereby reducing the size of the drive unit 100. When this drive unit 100 is applied to the control valve 1, referring to Figures 1 to 3, the control valve 1, which is an embodiment of the present invention, can shorten the pitch between the first input shaft 223 and the second input shaft 323, and the pitch between the first valve body 62 and the second valve body 63, thereby realizing the miniaturization of the control valve.

[0021] As described above, the driving device 100 includes the first motor 21 and the second motor 31 that are arranged with a gap between them. Furthermore, by arranging the first end of the first motor 21 and the first end of the second motor 31 adjacent to each other, the first power supply terminal 212 located at the first end of the first motor 21 and the second power supply terminal 312 located at the first end of the second motor 31 are arranged adjacent to each other, facilitating concentrated wiring of multiple lead wire segments 401, and when projected along the height direction of the drive device 100 onto the bottom wall portion 11, the orthogonal projections of at least a portion of the wiring segments 402 are arranged so as to at least partially overlap with the orthogonal projections of the first body 211 and / or the orthogonal projections of the second body 311. As a result, all of the wiring segments 402 are arranged in the gap between the first body 211 and the second body 311, whereas the embodiment of the present invention reduces the number of wiring segments 402 arranged between the first body 211 and the second body 311, shortens the pitch between the first body 211 and the second body 311, and further reduces the longitudinal size of the drive device. When this drive device is applied to the control valve 1, the size of the control valve 1 is further reduced, making it easy to miniaturize the control valve 1, and contributing to its widespread use and application.

[0022] Here, the above embodiments are intended to illustrate the present invention and do not limit the present invention. For example, the definitions of directions such as "front", "back", "left", "right", "upper", and "lower" have been described in detail in this specification with reference to the above embodiments. However, as can be understood by those skilled in the art, amendments, references, or equivalent replacements may be made to the present invention, and all improvements that do not depart from the spirit and scope of the present invention should fall within the scope of the claims of this application.
