[0018] Figure 1 Cross-sectional view of the water pump and fan integrated structure according to an embodiment of the present application; Figure 2 For Figure 1A partial enlarged view of the integrated water pump and fan structure shown; Figure 3 for Figure 1 A schematic diagram of a partition disk with an integrated water pump and fan structure; Figure 4 for Figure 1 The diagram shows the distribution of the first and second magnets on the mounting plate in the integrated water pump and fan structure. Figures 1-4 As shown, the integrated structure of the water pump and fan includes a water pump base 1, a drive assembly 2, an impeller 3, a shaft sleeve 4, a partition disk 5, a magnetic force generating device 6, a first engaging assembly 7, and a fan 8.
[0019] The pump base 1 has a receiving cavity, and the pump base 1 has a first opening 101 and a second opening communicating with the receiving cavity at opposite axial ends. The drive assembly 2 is disposed in the receiving cavity. The impeller 3 is driven to the end of the drive assembly 2 facing the first opening 101, and the pump base 1 has a drain outlet circumferentially corresponding to the impeller 3. The bushing 4 is driven to the end of the drive assembly 2 facing the second opening. The partition disk 5 is circumferentially fixedly connected to the bushing 4 and has a first magnetic isolation groove 51 through it. The magnetic force generating device 6 is disposed on the side of the partition disk 5 facing the first opening 101, and is connected to the inner cavity of the pump base 1. The wall is fixedly connected and is set corresponding to the first magnetic isolation groove 51; the first attraction component 7 is fitted with a bushing 4, is rotatably connected to the bushing 4, and extends to the side of the partition disk 5 facing the second opening, and is set corresponding to the magnetic force generating device 6. Under the action of the magnetic force generating device 6, it is attracted to the partition disk 5 or detached from the partition disk 5; the fan 8 includes a mounting plate 81 and fan blades 82 fixed to the circumference of the mounting plate 81. The mounting plate 81 is rotatably connected to the first attraction component 7, and a plurality of first magnets 9 are fixedly fixed circumferentially on the side surface facing the first attraction component 7. The first magnets 9 are set corresponding to the first attraction component 7.
[0020] In use, the drive assembly 2 and the magnetic force generating device 6 are activated. The drive assembly 2 drives the impeller 3 connected to it to rotate synchronously. The rotation of the impeller 3 creates a low-pressure zone at its center, causing external water to be drawn in through the first opening 101 under the action of pressure difference. The centrifugal force generated by the rotation of the impeller 3 throws the water from the center of the impeller 3 to the edge, and discharges it to the outside through the drain port on the water pump base 1. At the same time, the drive assembly 2 drives the bushing 4 connected to it to rotate synchronously. The rotation of the bushing 4 causes the partition disk 5 fixedly connected to it to rotate as well. The magnetic force generated by the magnetic force generating device 6 acts on the first attraction assembly 7, causing the first attraction assembly 7 to attract the partition disk 5. Thus, the first attraction assembly 7 rotates synchronously with the partition disk 5. During the rotation, the first attraction assembly 7 is magnetized by the first magnet 9 arranged circumferentially on the mounting plate 81. The rotating induced magnetic field generated by the magnetized first attraction assembly 7 generates torque with the first magnet 9, causing the mounting plate 81 to rotate at a different speed than the partition disk 5, which in turn drives the fan blade 82 fixedly connected to the mounting plate 81 to rotate, ultimately generating airflow.
[0021] By adopting the integrated structure of the water pump and fan of the present invention, the impeller 3 of the water pump and the fan blades 82 of the fan 8 can be driven to rotate simultaneously by the same set of drive components 2. Compared with the separate structure of water pump and fan 8, the structure is simplified, which helps to reduce the space occupied and reduce the difficulty of operation. After reducing the number of structural components, fewer parts need to be maintained, thus reducing the failure rate. Moreover, the drive component 2 indirectly drives the mounting plate 81 and the fan blades 82 to rotate through the partition disk 5 and the first suction component 7, so that the fan blades 82 and the impeller 3 can rotate at different speeds at the same time, which improves the flexibility of use.
[0022] like Figures 1-4 As shown, in this embodiment, the pump base 1 is a stepped hollow shell, symmetrically arranged about the axis. The cross-sectional diameter of the inner wall is larger at the left end and smaller at the right end. The pump base 1 has a first opening 101 at the right end and a second opening at the left end. The drive assembly 2 is coaxially arranged with the pump base 1 in the receiving cavity. The right end of the drive assembly 2 is driven by the impeller 3, and the left end is driven by the bushing 4. A circular spacer disk 5 is fitted on the outer wall of the bushing 4, and the spacer disk 5 is fixedly connected to the bushing 4 by a semi-circular key. The spacer disk 5 extends circumferentially towards the inner wall of the pump base 1 and is arranged perpendicular to the axis of the bushing 4. A first magnetic isolation groove 51 is formed through the spacer disk 5, corresponding to the magnetic force generating device 6. Figure 3 As shown, in this embodiment, the first magnetic isolation groove 51 is an arc-shaped hole, and multiple first magnetic isolation grooves 51 are spaced apart along the circumference of the magnetic disk 5. Figure 2 As shown, the width of the first magnetic isolation groove 51 is much larger than the gap between the disk 5 and the first attraction component 7, as well as the gap between the disk 5 and the magnetic force generating device 6. When the magnetic field generated by the magnetic force generating device 6 propagates along the disk 5 to the first magnetic isolation groove 51, the magnetic field bypasses the first magnetic isolation groove 51 and propagates along the first attraction component 7 because the magnetic permeability of the first attraction component 7 is much stronger than that of air. Finally, it returns to the magnetic force generating device 6 to form a loop. A magnetic force generating device 6 is disposed between the partition disk 5 and the drive assembly 2, and is circumferentially fixedly connected to the inner wall of the water pump base 1. A first engaging assembly 7 is fitted with a bushing 4 and extends circumferentially between the partition disk 5 and the fan 8, parallel to the partition disk 5. The mounting plate 81 of the fan 8 is rotatably connected to the first engaging assembly 7, and the mounting plate 81 is coaxially arranged with the bushing 4. On one side of the mounting plate 81 facing the first engaging assembly 7, multiple first magnets 9 are fixedly fixed circumferentially at intervals. The magnetic pole directions of all first magnets 9 are parallel to the axial direction of the mounting plate 81, and the magnetic pole directions of adjacent first magnets 9 are opposite. Figure 4As shown, the first magnet 9 is arranged near the shaft of the mounting disc 81, and the two adjacent colors represent opposite magnetic pole directions. A plurality of vanes 82 are arranged along the circumference of the mounting disc 81. The magnetic force generating device 6 is a mature prior art, and the specific structure can be selected as needed. The first suction assembly 7 has a certain elasticity, so that when the magnetic force generating device 6 is started, the first suction assembly 7 is attracted to the magnetic disk 5 under the suction of the magnetic force, and when the magnetic force generating device 6 is turned off, the magnetic force disappears, and the first suction assembly 7 is separated from the magnetic disk 5 and restored to its original position.
[0023] Optionally, the driving assembly 2 comprises a fixed shaft 21, a rotor 22, a first bearing 23, a stator 24 and an isolation ring 25. The fixed shaft 21 is fixedly connected with the water pump base 1; the rotor 22 is sleeved with the fixed shaft 21 and is rotatably connected with the fixed shaft 21, and the circumferential surface of the rotor 22 is fixedly connected with the permanent magnet 26; the impeller 3 is fixedly connected with one end of the rotor 22 facing the first opening 101; the first bearing 23 is sleeved with one end of the rotor 22 facing the second opening and is fixedly connected with the rotor 22; the first bearing 23 is sleeved with one end of the shaft sleeve 4 facing the first opening 101 and is fixedly connected with the shaft sleeve 4; the stator 24 surrounds the rotor 22 and is fixedly connected with the inner wall of the water pump base 1; the isolation ring 25 is fixedly connected with the inner wall of the water pump base 1 at one end of the stator 24 facing the first opening 101, is inserted between the stator 24 and the permanent magnet 26, and extends to be fixedly connected with the outer ring of the first bearing 23. This kind of arrangement simplifies the structure of the driving assembly 2, and is convenient for assembly and operation.
[0024] As shown in Figure 1 and Figure 2 In this embodiment, the fixed shaft 21 is coaxially arranged with the water pump base 1 and is fixedly connected with the water pump base 1, the outer wall of the fixed shaft 21 is sleeved with the rotor 22, and the two are rotatably connected, one end of the rotor 22 facing the second opening, that is, Figure 1 the outer wall of the left end of the rotor 22 is sleeved with the first bearing 23, and the left end of the first bearing 23 is also sleeved with the outer wall of the shaft sleeve 4 and is fixedly connected with the shaft sleeve 4, one end of the rotor 22 facing the first opening 101, that is, Figure 1The right end of the middle rotor 22 is fixedly connected with the impeller 3. The outer wall of the rotor 22 is sleeved with a permanent magnet 26, the permanent magnet 26 is sleeved with a separation ring 25 in the circumferential direction, and the separation ring 25 keeps a certain gap with the permanent magnet 26. The separation ring 25 includes a fixed segment and a separation segment which are connected vertically. The fixed segment is arranged vertically to the axis of the water pump base 1 as a whole, and the outer wall of the fixed segment is fixedly connected with the inner wall of the water pump base 1 in the circumferential direction. The separation segment is arranged parallel to the axis of the water pump base 1, and surrounds the permanent magnet 26. The inner wall of the left end of the separation segment is fixedly connected with the outer ring of the first bearing 23. The stator 24 is arranged in the space between the outer wall of the separation ring 25 and the inner wall of the water pump base 1. Under the separation action of the separation ring 25, the water flow entering from the first opening 101 is separated in the space enclosed by the water pump base 1, the separation ring 25, the first bearing 23 and the rotor 22, so that the water flow cannot flow to the space where the stator 24, the magnetic force generating device 6, the magnetic separation disc 5 and the first suction assembly 7 are located. The stator 24 is circumferentially wound with a coil. When the coil is electrified, the permanent magnet 26 on the rotor 22 cooperates with the stator 24 to provide a deflection force, drive the rotor 22 to rotate, and drive the impeller 3 fixedly connected with the rotor 22 to rotate. The rotation of the impeller 3 causes the external water flow to be sucked in through the first opening 101, and to be thrown to the edge under the action of the centrifugal force generated by the rotation of the impeller 3, and to be discharged to the outside through the water outlet on the water pump base 1. At the same time, the rotation of the rotor 22 drives the inner ring of the first bearing 23 fixedly connected with the rotor 22 to rotate, and then the inner ring of the first bearing 23 drives the shaft sleeve 4 fixedly connected with the inner ring of the first bearing 23 to rotate synchronously. The process of driving the rotor 22 to rotate is a mature prior art, and the specific principle will not be described here.
[0025] Optionally, the magnetic force generating device 6 includes an annular iron core 61 and a first coil 62. The annular iron core 61 is sleeved with the first bearing 23, is fixedly connected with the outer ring of the first bearing 23, and is fixedly connected with the inner wall of the water pump base 1 in the circumferential direction. The annular iron core 61 is provided with a first ring groove on one side surface facing the magnetic separation disc 5. The first coil 62 is arranged in the first ring groove and corresponds to the first magnetic separation groove 51. This kind of arrangement simplifies the structural composition of the magnetic force generating device 6, and is convenient for assembly and operation.

Corresponding to the circumferential direction of the first coil 62, a plurality of first magnetic separation grooves 51 are arranged on the magnetic separation disc 5 in a spaced manner, and the first magnetic separation grooves 51 are arc-shaped holes. When the rotor 22 drives the shaft sleeve 4 and the magnetic separation disc 5 fixedly connected thereto directly or indirectly to rotate, the first coil 62 is controlled to be electrified, a magnetic field is generated after the first coil 62 is electrified, and a magnetic force is generated on the first suction assembly 7 on the other side of the magnetic separation disc 5, so that the first suction assembly 7 is attracted to the magnetic separation disc 5 and rotates synchronously with the magnetic separation disc 5, and then drives the mounting disc 81 and the fan blades 82 to rotate under the action of the torque generated by the first magnet 9; the first coil 62 is controlled to be de-energized, the magnetic field disappears, the attraction of the first suction assembly 7 disappears, the first suction assembly 7 is separated from the magnetic separation disc 5, and the first suction assembly 7 cannot rotate synchronously with the magnetic separation disc 5, and then the mounting disc 81 and the fan blades 82 stop rotating. The first coil 62 is connected to an external control circuit through a wire, and the energization or de-energization of the first coil 62 is controlled. It is a mature prior art, and the specific control circuit will not be described here.
[0027] Optionally, the first suction assembly 7 comprises a first transmission disc 71, a first elastic member 72 and a first clutch disc 73. The first transmission disc 71 is sleeved with the shaft sleeve 4, rotatably connected with the shaft sleeve 4, and extends to the side of the magnetic separation disc 5 facing the second opening, and is arranged corresponding to the first coil 62, and the mounting disc 81 is rotatably connected with the first transmission disc 71; the first elastic member 72 is fixedly connected with the side surface of the first transmission disc 71 facing the first coil 62; and the first clutch disc 73 is fixedly connected with the side surface of the first elastic member 72 facing the first coil 62. This kind of arrangement simplifies the structure of the first suction assembly 7, so that the first suction assembly 7 can not only ensure the relative position stability with the shaft sleeve 4, but also realize the suction or separation with the magnetic separation disc 5.

The outer wall of the first fixed ring of the part of the shaft sleeve 4 sleeved with the first transmission disc 71 is sleeved and fixed with the third bearing 16, the mounting disc 81 of the fan 8 is fixedly connected with the outer ring of the third bearing 16, realizing the rotatable connection between the mounting disc 81 and the first transmission disc 71. After the first coil 62 is electrified, the magnetic field generated by the first coil 62 acts on the first clutch disc 73 matched with the magnetic shielding disc 5, so that the first clutch disc 73 has a tendency to move towards the magnetic shielding disc 5, the first elastic member 72 is elastically deformed, and finally the first clutch disc 73 is attracted to the magnetic shielding disc 5 and rotates synchronously with the magnetic shielding disc 5, thereby driving the first elastic member 72 and the first transmission disc 71 to rotate; after the first coil 62 is deenergized, the magnetic field disappears, the first elastic member 72 restores the deformation, and drives the first clutch disc 73 to separate from the magnetic shielding disc 5 and return to the initial position. According to the actual application, the specific shape and size of the first transmission disc 71, the first elastic member 72 and the first clutch disc 73 can be adjusted, as long as the first transmission disc 71 can be stably sleeved outside the shaft sleeve 4, the first elastic member 72 is deformed under the action of elastic force after the first coil 62 is electrified to generate a magnetic field, so that the first clutch disc 73 can be attracted to the magnetic shielding disc 5, and then the first transmission disc 71 can be driven to rotate synchronously.

After the second coil 63 is controlled to be electrified, the magnetic field generated by the second coil 63 acts on the second clutch disk 1003, so that the second clutch disk 1003 has a tendency to move towards the isolation disk 5, the second elastic member 1002 is elastically deformed, and finally the second clutch disk 1003 is attracted to the isolation disk 5 and rotates synchronously with the isolation disk 5, thereby driving the second elastic member 1002 and the second transmission disk 1001 to rotate, and the second transmission disk 1001 is magnetized by the second magnets 11 arranged in the circumferential direction on the mounting disk 81 in the process of rotating, the induced magnetic field generated by the magnetized second transmission disk 1001 generates a torque with the second magnets 11, thereby driving the mounting disk 81 to rotate at a speed different from that of the rotor 22. Since the number of second magnets 11 is greater than that of first magnets 9, the generated torque is greater, and therefore, when the second coil 63 is electrified alone, the speed of the fan 8 is faster than that when the first coil 62 is electrified alone.
[0031] By means of the cooperation of the first coil 62 and the second coil 63, different speeds of the fan 8 can be driven according to requirements: (1) neither the first coil 62 nor the second coil 63 is electrified, when the rotor 22 rotates, the impeller 3, the shaft sleeve 4 and the isolation disk 5 are driven to rotate, but the first clutch disk 73 and the second clutch disk 1003 are not attracted to the isolation disk 5 and cannot rotate, so the fan 8 does not rotate; (ii) the first coil 62 is energized, the second coil 63 is not energized, when the rotor 22 rotates, the impeller 3 is driven to rotate, at the same time, the shaft sleeve 4 and the magnetic separation disc 5 are driven to rotate, the first clutch disc 73 is attracted to the magnetic separation disc 5 under the action of the magnetic field generated by the first coil 62, the second clutch disc 1003 is not attracted to the magnetic separation disc 5, the first clutch disc 73 drives the first transmission disc 71 to rotate synchronously, the first transmission disc 71 is magnetized by the first magnet 9, the rotating induced magnetic field generates torque with the first magnet 9, and the fan 8 is driven to rotate at a low speed differential; (iii) the first coil 62 is not energized, the second coil 63 is energized, when the rotor 22 rotates, the impeller 3 is driven to rotate, at the same time, the shaft sleeve 4 and the magnetic separation disc 5 are driven to rotate, the first clutch disc 73 is not attracted to the magnetic separation disc 5, the second clutch disc 1003 is attracted to the magnetic separation disc 5 under the action of the magnetic field generated by the second coil 63, and the second transmission disc 1001 is driven to rotate synchronously, the second transmission disc 1001 is magnetized by the second magnet 11, the rotating induced magnetic field generates torque with the second magnet 11, and the fan 8 is driven to rotate at a medium speed differential; (iv) the first coil 62 and the second coil 63 are both energized, when the rotor 22 rotates, the impeller 3 is driven to rotate, at the same time, the shaft sleeve 4 and the magnetic separation disc 5 are driven to rotate, the first clutch disc 73 is attracted to the magnetic separation disc 5 under the action of the magnetic field generated by the first coil 62, and the first transmission disc 71 is driven to rotate synchronously, the first transmission disc 71 is magnetized by the first magnet 9, the rotating induced magnetic field generates torque with the first magnet 9, the second clutch disc 1003 is attracted to the magnetic separation disc 5 under the action of the magnetic field generated by the second coil 63, and the second transmission disc 1001 is driven to rotate synchronously, the second transmission disc 1001 is magnetized by the second magnet 11, the rotating induced magnetic field generates torque with the second magnet 11, and the two torques are superimposed, and the fan 8 is driven to rotate at a high speed differential.
[0032] Optionally, the water pump and fan integrated structure further comprises a plurality of deceleration magnet groups 12, the plurality of deceleration magnet groups 12 are arranged at intervals along the circumference of the second transmission disc 1001, each deceleration magnet group 12 comprises a third magnet 121 and a fourth magnet 122 arranged oppositely, the third magnet 121 is fixed to the second transmission disc 1001, and the fourth magnet 122 is fixed to the inner wall of the water pump base 1. When the magnetic separation disc 5 rotates with the shaft sleeve 4, the second transmission disc 1001 may rotate slightly with the rotation of the magnetic separation disc 5 due to the friction between components, and the above-mentioned arrangement can ensure that the second transmission disc 1001 remains stationary when the second coil 63 is not energized by means of the deceleration magnet group 12.
[0033] As Figure 1 and Figure 2As shown, in the embodiment, the second transmission disc 1001 is rotatably connected to the isolation disc 5 through the fourth bearing 17. When the isolation disc 5 rotates with the shaft sleeve 4 and in turn drives the inner ring of the fourth bearing 17 to rotate, the outer ring has the possibility of rotating and driving the second transmission disc 1001 to rotate due to the friction between the inner ring and the outer ring. The magnetic pole direction of the deceleration magnet group 12 is parallel to the fan axis direction, and the magnetic pole directions of the third magnet 121 and the fourth magnet 122 are the same. The two are attracted to each other, and under the attraction of the third magnet 121 and the fourth magnet 122 in the same deceleration magnet group 12, the rotation trend of the second transmission disc 1001 is offset. In the embodiment, the deceleration magnet group 12 is arranged on a set of surfaces of the second transmission disc 1001 and the inner wall of the water pump base 1 that are oppositely arranged along the axis direction of the rotor 22. According to actual application conditions, the deceleration magnet group 12 can also be arranged on other opposite surfaces of the second transmission disc 1001 and the inner wall of the water pump base 1. The number of deceleration magnet groups 12 can also be adjusted as needed. As long as the second transmission disc 1001 can remain stationary under the magnetic force of the deceleration magnet group 12 without the second coil 63 being energized, and does not affect the normal rotation of the second transmission disc 1001 when the second coil 63 is energized.
[0034] Optionally, the water pump and fan integrated structure further comprises a first sealing ring 13 arranged between the rotor 22 and the first bearing 23.

[0036] Optionally, the water pump and fan integrated structure further comprises a second sealing ring 14 arranged between the isolation ring 25 and the first bearing 23. This arrangement seals the gap that may exist between the isolation ring 25 and the outer ring of the first bearing 23 by means of the second sealing ring 14, preventing the water flow entering through the first opening 101 from flowing into the space on the side of the isolation ring 25 facing the stator 24.
[0037] As shown in Figure 1 and Figure 2 , the second sealing ring 14 surrounds the first bearing 23 and is embedded between the outer ring of the first bearing 23 and the isolation ring 25.

In this way, the fan blade 82 and the mounting disc 81 are covered in the protective frame 83, preventing the fan blade 82 from damaging other components during rotation and preventing the fan blade 82 from being damaged.
[0039] The application further provides a vehicle comprising the water pump and fan integrated structure according to any one of the above embodiments.
[0040] With the vehicle, the impeller 3 of the water pump and the fan blade 82 of the fan 8 can be simultaneously driven to rotate by the same set of driving assembly 2, compared with the split structure of the water pump and the fan 8, the structure is simplified, the occupied space is reduced, the operation difficulty is reduced, the number of components is reduced, the number of components to be maintained is reduced, the failure rate is reduced, and the fan blade 82 and the impeller 3 can be simultaneously rotated at different speeds by the indirect driving of the mounting disc 81 and the fan blade 82 by the magnetic isolation disc 5 and the first suction assembly 7, so that the flexibility of use is improved.
