As a specific embodiment of the present invention, the housing assembly 10 of this embodiment further includes the spiral cases 13 disposed at two ends, each spiral case 13 is disposed with a set of water inlets 11 and water outlets 12, two impellers 22 are disposed near two spiral cases 13, and the impeller 22 pushes the liquid flowing into the water inlet 11 near the spiral case 13, so that the liquid flows to the water outlet 12 at the same spiral case 13.
More specifically, the housing assembly 10 of the present embodiment may further include a housing 14, and the housing 14 and the two volutes 13 are connected by a fastener 15, so that the entire housing assembly 10 forms a hollow structure to enclose the motor assembly 20 inside the housing assembly 10. The fastener 15 in this embodiment may be a combination of a screw, a bolt, and a nut. Of course, in other embodiments, the housing 14 and the volute 13 may be connected by other means, such as welding, clamping, etc.
As a specific embodiment, the axes of the two water inlets 11 of the present embodiment are parallel to the axis of the rotor 21, and the axes of the two water outlets 12 are at a preset angle with the axis of the rotor 21, and the preset angle is 80-90 °. That is, the water outlet 12 may be perpendicular to the water inlet 11, or may be at an angle similar to the perpendicular. As other embodiments, the axes of the two water inlets 11 are arranged coaxially with the rotor 21.
In the present embodiment, for example, as shown in fig. 1, the left end of the left volute 13 is provided with a water inlet 11, and the upper left part is provided with a water outlet 12. The right end of the right volute 13 is provided with a water inlet 11, and the upper right part is provided with a water outlet 12. The perpendicular alignment of the inlet 11 and outlet 12 facilitates better flow of liquid from the inlet 11 into the housing assembly 10 to the outlet 12.
Fig. 3 is a cross-sectional view of a dual drive water pump according to an embodiment of the present invention; as a specific example, the motor assembly 20 may further include a rotating shaft 23, a stator 24, and a water stop sleeve 25. The rotation shaft 23 is provided in the housing assembly 10 with both ends rotatably abutting at both volutes 13. The stator 24 is disposed outside the rotor 21, and the stator 24 generates an alternating magnetic field under the action of the alternating electric field to drive the rotor 21 to rotate. The water blocking sleeve 25 is disposed between the rotor 21 and the stator 24 for supporting the rotor 21 while preventing liquid in the rotor 21 from entering the stator 24. The double-drive water pump 100 of the present embodiment is coaxially arranged in sequence from inside to outside by the rotating shaft 23, the rotor 21, the water-stop jacket 25, the stator 24 and the housing 14. Specifically, in the present embodiment, the rotating shaft 23 and the rotor 21 may be disposed to rotate relatively or may be disposed to rotate together as an integral structure.
Fig. 4 is a schematic structural view of a water partition jacket according to an embodiment of the present invention. Specifically, as shown in fig. 4, the water partition jacket 25 of the present embodiment may include a first blocking portion 251 and a second blocking portion 252. The first blocking portion 251 is disposed coaxially with the rotating shaft 23, and the first blocking portion 251 is a through structure. The number of the second blocking portions 252 is two, and the second blocking portions 252 are respectively disposed at both end portions of the first blocking portion 251, each second blocking portion 252 extends outward along a direction perpendicular to the axis of the rotating shaft 23, and the housing 14, the second blocking portion 252 and the scroll 13 are sequentially disposed and connected by the fastening member 15. The first blocking portion 251 and the second blocking portion 252 are connected without a gap, and together block the liquid flowing from the water inlet 11 of the volute casing 13 to the rotor 21 from entering the space where the stator 24 is located.
Specifically, in this embodiment, the spaces between the water blocking sleeves 25 are communicated, and after the water inlets 11 of the volutes 13 at the two sides enter the volutes 13, the water can flow from the inside of the water blocking sleeve 25 and flow from the volute 13 at one end to the volute 13 at the other end. However, during the rotation of the rotor 21 inside the water-stop sleeve 25, due to the action of the impellers 22 at the two ends of the rotor 21, most of the liquid entering the volute casing 13 from the water inlet 11 at one end flows out from the water outlet 12 at the same end, and a small part of the liquid flows to the water outlet 12 at the middle position or the other end. In the embodiment, the space in the water blocking sleeve 25 can be designed into a through structure (as shown in fig. 3), so that one rotor 21 can drive two impellers 22, and meanwhile, under the condition that liquid inlet and outlet at two ends are not influenced, the flow of the liquid between the rotor 21 and the water blocking sleeve 25 has a self-cooling effect on the whole water pump, and a cooling system is not required to be additionally used, so that the cost is reduced.
In addition, in other embodiments, the space inside the water stop sleeve 25 of the dual drive water pump 100 may be designed as a non-through structure. For example, a baffle plate or the like may be used to divide the internal space of the water-blocking jacket 25 into at least two closed spaces, and to divide the left end and the right end, so as to prevent the liquid entering the volute 13 from the water inlet 11 from the left end and the right end from streaming mutually. The dual drive water pump 100 of this embodiment may be used in some vehicles where coolant is not available to flow in series.
As a specific example, in the present embodiment, the dual-drive water pump 100 may further include at least two sealing rings 26 (as shown in fig. 2 and 3), and each sealing ring 26 is disposed between each volute 13 and the corresponding second blocking portion 252.
More specifically, the second blocking portion 252 is provided with a step 253 (shown in fig. 4) at a side surface near the corresponding volute 13, and the seal ring 26 is provided at the step 253.
In this embodiment, the structure of the second blocking portion 252 may be designed according to the volume, strength, and other requirements of a specific water pump.
In addition, the dual drive water pump 100 of the present embodiment may further include a control device 30, and the control device 30 is disposed at the housing 14 and connected to the stator 24. Specifically, the control device 30 is mainly used to provide power to the dual drive water pump 100, and control and feed back various information of the dual drive water pump 100.
As a specific example of the present invention, the present embodiment further provides a vehicle, which may include the above dual drive water pump 100.
Thus, it should be appreciated by those skilled in the art that while a number of exemplary embodiments of the invention have been shown and described in detail herein, many other variations and modifications can be made, consistent with the principles of the invention, which are directly determined or derived from the disclosure herein, without departing from the spirit and scope of the invention.
