[0019] The features and exemplary embodiments of various aspects of the present invention will be described in detail below. To make the objectives, technical solutions, and advantages of the present invention more clearly understood, the present invention will be further described in detail with reference to the accompanying drawings and specific embodiments. As used herein, relational terms such as "first" and "second" are merely used to distinguish one component from another having the same name, and do not necessarily require or imply any actual relationship or order between these components.

[0020] like Figures 1 to 4 As shown, an embodiment of the present invention provides a control valve 1, comprising a drive device 100, an upper cover 66, a valve body 61, a first valve core 62, and a second valve core 63. At least a portion of the first valve core 62 and at least a portion of the second valve core 63 are located within the valve body 61, and the first valve core 62 and the second valve core 63 can be driven to rotate independently, so that the conducting cavities of the two valve cores connect the valve ports of different control valves 1, thereby realizing the control function of the control valve 1 over the fluid. Furthermore, at least a portion of the first valve core 62 and at least a portion of the second valve core 63 are located between the upper cover 66 and the valve body 61. The upper cover 66 can be sealed with the valve body 61 to prevent leakage of the fluid. The drive device 100 is located on the side of the upper cover 66 facing away from the valve body 61, and the drive device 100 can drive the first valve core 62 and the second valve core 63 to rotate.

[0021] Further reading Figures 1 to 4 The control valve 1 has a first chamber 611, a second chamber 612, and a communication channel 613 between the first chamber 611 and the second chamber 612. The communication channel 613 can realize the mutual communication of fluids in the first chamber 611 and the second chamber 612. 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, Figure 1 In the embodiment, the arrangement direction of the first chamber 611 and the second chamber 612 is perpendicular to the height direction of the control valve 1. Figure 4The 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 sealed, or the first side wall portion 614 and the second side wall portion 615 are integrally formed. The first side wall portion 614 is the peripheral wall of the first chamber 611 or at least a part of the peripheral wall, and the second side wall portion 615 is the peripheral wall of the second chamber 612 or at least a part of the peripheral wall. Figure 4 The valve body 61 may further include a connecting wall portion 618 connecting the first side wall portion 614 and the second side wall portion 615. The connecting wall portion 618 is located between the first side wall portion 614 and the second side wall portion 615.

The first side wall portion 614, the second side wall portion 615 and the connecting wall portion 618 can be formed as one piece. To achieve fluid circulation, the control valve 1 has a first channel 616 and a second channel 617. One end of the first channel 616 penetrates the first sidewall portion 614 to form a first communication port 6141, which communicates with the first chamber 611. The other end of the first channel 616 penetrates the outer surface of the control valve 1 to form a first valve port, allowing fluid to enter or exit the control valve 1 from the first valve port 1011. One end of the second channel 617 penetrates the second sidewall portion 615 to form a second communication port 6151, which communicates with the second chamber 612. The other end of the second channel 617 penetrates the outer surface of the control valve 1 to form a second valve port, allowing fluid to enter or exit the control valve 1 from the second valve port. In the control valve provided in this embodiment of the present invention, by rotating the first valve core 62 and / or the second valve core 63, multiple conduction modes can be achieved between multiple first valve ports and between the first valve port and the second valve port, thereby realizing the control function of the control valve 1 on the fluid.

[0022] To drive the rotation of the first valve core 62 and the second valve core 63, as shown in FIG. Figure 1 and Figure 5As shown, an embodiment of the present invention further provides a driving device 100, including a shell 10 and a driving assembly, the driving assembly including a first driving assembly 20 and a second driving assembly 30, the driving device 100 has a accommodating cavity 101, the shell 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 the wall portion of the accommodating cavity 101 or at least a part of the wall portion, the side wall portion 12 is the peripheral wall of the accommodating cavity 101 or at least a part of the peripheral wall, along the two ends of the length direction of the driving device 100, the main body of the positive projection of the side wall portion 12 on the bottom wall portion 11 is an arc shape, which can reduce the size of the driving device 100. At least part of the first drive assembly 20 and at least part of the second drive assembly 30 are located in the accommodating cavity 101. The first drive assembly 20 and the second drive assembly 30 are spaced apart and arranged along the length direction of the drive device 100. The first drive assembly 20 includes a first motor 21, which includes a first body 211, a first power supply terminal 212 and a first output shaft 213. The first power supply terminal 212 is located at the first end of the long axis direction of the first body 211, and the first output shaft 213 is located at the second end of the long axis direction of the first body 211. The second drive assembly 30 includes a second motor 31, which includes a second body 311, a second power supply terminal 312 and a second output shaft 313. The second power supply terminal 312 is located at the first end of the long axis direction of the second body 311, and the second output shaft 313 is located at the second end of the long axis direction of the second body 311. The first end of the first body 211 is adjacent to the first end of the second body 311 and is 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, which are respectively a positive power supply terminal and a negative power supply terminal, and the second motor 31 includes two second power supply terminals 312, which are respectively a positive power supply terminal and a negative power supply terminal.

[0023] Combine Figures 5 to 9In order to control the rotation of the first motor 21 and the second motor 31, the driving device 100 further includes a plurality of wire segments 401, and the plurality of wire segments 401 are electrically connected to the first power supply terminal 212 and the second power supply terminal 312 respectively. In a specific implementation, the driving device 100 further includes four wire segments 401, and the four wire segments 401 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 in a one-to-one correspondence, so that the electrical signal is transmitted to the corresponding power supply terminal via the wire segments 401. Each wire segment 401 includes a routing segment 402, which is disposed adjacent to the bottom wall portion 11. At least a portion of the routing segment 402 extends in a direction that intersects with the length direction of the drive device 100. Among the plurality of wire segments 401, when projected toward the bottom wall portion 11 along the height direction of the drive device 100, the orthographic projections of at least some of the routing segments 402 at least partially overlap with the orthographic projections of the first body 211 and / or the orthographic projections of the second body 311. At this time, along the length direction of the drive device 100, the width of the gap between the first body 211 and the second body 311 is less than the maximum width between the two routing segments 402. For example, Figure 7 In the embodiment, the orthographic projection of one of the routing segments 402 electrically connected to the first power supply terminal 212 on the bottom wall portion 11 overlaps with the orthographic projection of the first main body 211 on the bottom wall portion 11, and the orthographic projection of one of the routing segments 402 electrically connected to the second power supply terminal 312 on the bottom wall portion 11 overlaps with the orthographic projection of the second main body 311 on the bottom wall portion 11. Compared with arranging the four routing segments 402 side by side in the gap between the first main body 211 and the second main body 311, the gap size between the first main body 211 and the second main body 311 can be effectively reduced, thereby reducing the length direction size of the driving device, which is conducive to miniaturization of the driving device.

[0024] Further reading Figures 5 to 9 In some embodiments, the driving device 100 further includes a control member 50, the control member 50 and the driving assembly are spaced apart and arranged along the width direction of the driving device 100, and each wire segment 401 is electrically connected to the control member 50, combined with Figure 5 、 Figure 8 and Figure 9The first drive assembly 20 and the second drive assembly 30 are located at one end of the drive device 100 in the width direction, and the control component 50 is located at the other end of the drive device 100 in the width direction.

The routing segment 402 of the second wire segment 42 and the routing segment 402 of the fourth wire segment 44 are buried in the bottom wall 11 or protrude from the bottom wall 11 and are located within the accommodating cavity 101. Projected toward the bottom wall 11 along the height direction of the driving device 100, the orthographic projection of the first routing segment 411 of the first wire segment 41 at least partially overlaps with the orthographic projection of the first body 211, the orthographic projection of the third routing segment 431 of the third wire segment 43 at least partially overlaps with the orthographic projection of the second body 311, and the orthographic projection of the second routing segment 421 of the second wire segment 42 and the orthographic projection of the fourth routing segment 441 of the fourth wire segment 44 are located in the gap between the orthographic projection of the first body 211 and the orthographic projection of the second body 311.

This arrangement can reduce signal interference between adjacent conductor segments and also alleviate faults such as circuit short circuits caused by condensation within the drive device.

[0026] Further reading Figure 5、 Figure 8 and Figure 9 In some embodiments, when projected toward the bottom wall 11 along the height direction of the drive device 100, the orthographic projection of the first drive assembly 20 and the orthographic projection of the second drive assembly 30 are symmetrically arranged about a symmetry axis M1 extending along the width direction of the drive device 100. The first drive assembly 20 and the second drive assembly 30 have the same structure. The first motor 21 further includes a first output shaft 213 located at the second end of the first body 211. The second motor 31 further includes a second output shaft 313 located at the second end of the second body 311. The first drive assembly 20 further includes a first transmission gear set 22, which can be transmission-connected to the first output shaft 213 via a worm gear.

When projected toward the bottom wall 11 along the height direction of the drive device 100, the orthographic projection of the control member 50 at least partially overlaps with the orthographic projections of the first transmission gear set 22 and the second transmission gear set 32, respectively. With the above arrangement, the width dimension of the drive device 100 can be reduced.

[0027] like Figure 8 、 Figure 9 and Figure 11 As shown, in some embodiments, the first transmission gear group 22 includes a first output gear 223 and a first shaft 224 coaxially arranged with the first output gear 223, and the first shaft 224 is located on the side of the first output gear 223 away from the bottom wall portion 11, the second transmission gear group 32 includes a second output gear 323 and a second shaft 324 coaxially arranged with the second output gear 323, and the second shaft 324 is located on the side of the second output gear 323 away from the bottom wall portion 11, the first output gear 223 and the second output gear 323 are 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 limited by the control member 50 to facilitate the limiting of the control member 50.

[0028] Further reading Figures 6 to 8In some embodiments, the control component 50 includes a control board 51 and a first potentiometer 521 and a second potentiometer 522 fixedly connected to the control board 51. The first potentiometer 521 and the second potentiometer 522 are located on the side of the control board 51 away from the bottom wall portion 11. The first shaft 224 passes through the control board 51 and is sleeved in the limiting hole of the first potentiometer 521. The second shaft 324 passes through the control board 51 and is sleeved in the limiting hole of the second potentiometer 522. The cross-sections of the limiting holes of the first potentiometer 521 and the second potentiometer 522 can be semicircular, and the cross-sections of the first shaft 224 and the second shaft 324 can also be semicircular. Through the above-mentioned arrangement, the rotating piece in the first potentiometer 521 rotates synchronously with the first shaft 224, and the rotating piece in the second potentiometer 324 rotates synchronously with the second potentiometer 522, so as to monitor the rotation of the motor and the valve core in the control valve. Compared with setting a magnetic element on the worm and setting a Hall element on the control part, the first potentiometer 521 and the second potentiometer 522 in the embodiment of the present invention can simplify the structure of the driving device and reduce the size of the driving device.

[0029] like Figure 11 and Figure 12 In some embodiments, the first transmission gear set 22 further includes a first input gear 221 and a first intermediate gear 222. The first input gear 221 can be connected to the first output shaft 213 through a worm gear, and the first output gear 223 is connected to the first input gear 221 through the 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 set 32 further includes a second input gear 321 and a second intermediate gear 322. The second input gear 221 and the first intermediate gear 222 are connected to the first output gear 223 through the first intermediate gear 222. The input gear 321 is in transmission connection with the second output shaft 313, and the second output gear 323 is in transmission connection with the second input gear 321 via 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. Optionally, d1 is 13.5 mm, d2 is 17.5 mm, d3 is 13.5 mm, d4 is 17.5 mm, and d5 is less than or equal to 66 mm. Through the above arrangement, the transmission gear set can stably transmit torque, and the center distance between the first output gear 223 and the second output gear 323 can be reduced, thereby reducing the size of the drive device 100. When the drive device 100 is applied to the control valve 1, combined with Figures 1 to 3 The control valve 1 provided in the embodiment of the present invention can also reduce the distance between the first input shaft 223 and the second input shaft 323 and the distance between the first valve core 62 and the second valve core 63, thereby facilitating miniaturization of the control valve.

[0030] In summary, the drive device 100 includes a first motor 21 and a second motor 31 that are spaced apart. The first end of the first motor 21 and the first end of the second motor 31 are disposed adjacent to each other, such that 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 disposed adjacent to each other. This facilitates the centralized wiring of multiple wire segments 401. By arranging the projections of at least some of the wiring segments 402 along the height direction of the drive device 100 toward the bottom wall 11 to at least partially overlap with the orthographic projections of the first body 211 and / or the orthographic projections of the second body 311, compared to arranging all the wiring segments 402 within the gap between the first body 211 and the second body 311, the embodiment of the present invention reduces the number of wiring segments 402 disposed between the first body 211 and the second body 311, thereby reducing the spacing between the first body 211 and the second body 311, and thereby reducing the lengthwise dimension of the drive device. When the drive device is applied to the control valve 1, the size of the control valve 1 can be further reduced, thereby facilitating miniaturization of the control valve 1 and promoting its widespread application.
