[0037] The embodiments of the present utility model are described in detail below. The embodiments described with reference to the accompanying drawings are exemplary. The embodiments of the present utility model are described in detail below.

[0038] Reference below Figure 1-Figure 14 The water pump 100 according to the embodiment of the present invention is described, and the water pump 100 can be applied to a vehicle.

[0039] Combination Figure 1-Figure 14 As shown, the water pump 100 according to the utility model may mainly include: a water pump body 10 and a power terminal 20, wherein a first electrical connector 11 is arranged in the water pump body 10, and the power terminal 20 may include a second electrical connector 21, and the second electrical connector 21 is detachably plugged and electrically connected to the first electrical connector 11.

[0040] Specifically, a stator 12 and a rotor 16 are provided in the water pump body 10. The stator 12 and the rotor 16 work together to convert the input current into magnetic force, and drive the impeller part of the rotor 16 to rotate, providing pressure for the medium, thereby conveying the liquid or pressurizing the liquid, thereby realizing the basic operation of the water pump 100.

[0041] Taking into account that the water pump body 10 requires an external power supply when working, a first electrical connector 11 is arranged in the water pump body 10, and the power connector 20 includes a second electrical connector 21. In this way, when using the water pump 100, the first electrical connector 11 and the second electrical connector 21 can be plugged and electrically connected to each other, and then the power connector 20 can be electrically connected to the external client, so that the water pump 100 can be powered to ensure the normal operation of the water pump 100.

[0042] Furthermore, since the plug-in electrical connection between the first electrical connector 11 and the second electrical connector 21 is detachable, the water pump body 10 and the power terminal 20 can be designed as a split type. On the one hand, when the client has different requirements for the interface or control method, there is no need to redesign the water pump body 10, and only the corresponding power terminal 20 needs to be replaced, thereby reducing the design verification time and cost of water pumps 100 with different interfaces under the same power, and saving production processes and costs. On the other hand, the water pump body 10 and the power terminal 20 can be replaced and repaired separately when damaged. For example, when the stator 12, rotor 16 and other parts in the water pump body 10 are damaged, the corresponding power terminal 20 can continue to be used, and when the second electrical connector 21 is damaged, the corresponding water pump body 10 can continue to be used, that is, only the damaged parts can be replaced and repaired, instead of repairing the entire water pump 100, which can reduce the maintenance cost.

[0043] Therefore, by providing a first electrical connector 11 in the water pump body 10, and making the power terminal 20 include a second electrical connector 21, the second electrical connector 21 is detachably plugged and electrically connected to the first electrical connector 11, so that the water pump body 10 and the power terminal 20 can be designed as a split type, which can not only adapt to the needs of different application scenarios and improve compatibility, but also allow the water pump body 10 and the power terminal 20 to be repaired separately, which can reduce maintenance costs.

[0044] Furthermore, the first electrical connector 11 and the second electrical connector 21 are interference fit. Specifically, by making the first electrical connector 11 and the second electrical connector 21 interference fit, there is no need to set other auxiliary installation structures, which can not only simplify the structure of the first electrical connector 11 and the second electrical connector 21, facilitate the electrical connection between the first electrical connector 11 and the second electrical connector 21, but also improve the stability of the electrical connection between the first electrical connector 11 and the second electrical connector 21, prevent the occurrence of electrical connection failure not intended by the user, and improve the reliability of the water pump 100.

[0045] Combination Figure 3-Figure 5 as well as Fig. 9 , Fig.11 and Fig.13 As shown, the first electrical connector 11 is a pin, and a slot 111 is provided in the pin, and the second electrical connector 21 is a column, and the column is plugged and matched with the slot 111, so that the pin and the column are electrically connected. Specifically, the first electrical connector 11 can be set as a pin, and the slot 111 is provided in the pin, and correspondingly, the second electrical connector 21 can be set as a column, so that when assembling the water pump 100, it is only necessary to extend the column into the slot 111, so that the column and the slot 111 are plugged and matched, and the electrical connection between the pin and the column can be achieved, that is, the electrical connection between the first electrical connector 11 and the second electrical connector 21 can be achieved, so that not only the speed and accuracy of the electrical connection between the first electrical connector 11 and the second electrical connector 21 can be improved, and the assembly efficiency of the water pump 100 can be improved, but also the stability and reliability of the electrical connection between the first electrical connector 11 and the second electrical connector 21 can be improved, and the reliability of the water pump 100 can be improved.

[0046] Combination Figure 5 , Fig. 9 , Fig.11 and Fig.13 As shown, the power terminal 20 can mainly include a mounting cover 22, a second electrical connector 21 and an external lead-out member 23. The second electrical connector 21 and the external lead-out member 23 are respectively arranged on both sides of the mounting cover 22, and the second electrical connector 21 is electrically connected to the external lead-out member 23.

[0047] Specifically, the second electrical connector 21 and the external lead-out member 23 are electrically connected, and by arranging the second electrical connector 21 and the external lead-out member 23 on both sides of the mounting cover 22, the mounting cover 22 can provide a shielding protection for the electrical connection line between the second electrical connector 21 and the external lead-out member 23, and the second electrical connector 21 and the external lead-out member 23 can be connected together to form the overall structure of the power connection head 20. Among them, the second electrical connector 21 can be electrically connected to the first electrical connector 11 of the water pump body 10, and the external lead-out member 23 can be connected to an external client, so that the water pump 100 can be powered through the power connection head 20 to ensure the normal operation of the water pump 100.

[0048] It should be noted that when the customer has new requirements for the setting position or setting direction of the external lead-out component 23, the position of the external lead-out component 23 relative to the mounting cover 22 can be changed without modifying the entire water pump 100, thereby further reducing the design verification time and cost and saving production processes and costs.

[0049] In some embodiments of the present invention, Figure 11-Figure 14 As shown, the power terminal 20 may further include: a built-in control board 24, which is disposed in the mounting cover 22, and the built-in control board 24 is electrically connected to the second electrical connector 21 and the external lead-out member 23 respectively.

[0050] Specifically, the power terminal 20 can include a built-in control board 24, which is arranged in the installation cover 22, and the built-in control board 24 is electrically connected to the second electrical connector 21 and the external lead-out member 23 respectively. In this way, after the first electrical connector 11 of the power terminal 20 and the second electrical connector 21 of the water pump body 10 are plugged and electrically connected, and the external lead-out member 23 of the power terminal 20 is connected to the external client, the operating state of the water pump 100 can be controlled through the built-in control board 24.

[0051] It should be noted that in other embodiments of the present invention, Figure 5-Figure 10 As shown, the power terminal 20 does not include: a built-in control board 24, and the power terminal 20 only includes: a mounting cover 22, a second electrical connector 21 and an external lead-out member 23, so that the first electrical connector 11 of the power terminal 20 and the second electrical connector 21 of the water pump body 10 can be plugged and electrically connected, and the external lead-out member 23 of the power terminal 20 is connected to the controller of the integrated module, so that the operating state of the water pump 100 can be controlled by the controller of the integrated module.

[0052] In some embodiments of the present invention, Figure 5-Figure 8As shown, the external lead-out member 23 is a swing wire 231. Specifically, the external lead-out member 23 can be set as a swing wire 231, so that after the first electrical connector 11 of the power supply terminal 20 and the second electrical connector 21 of the water pump body 10 are plugged and electrically connected, they can be connected to an external client through the swing wire 231. The swing wire 231 can be electrically connected to the external client by welding.

[0053] In other embodiments of the present invention, Figure 9-14 As shown, the external lead-out member 23 is a plug connector 232. Specifically, the external lead-out member 23 can be set as a plug connector 232, so that after the first electrical connector 11 of the power supply terminal 20 and the second electrical connector 21 of the water pump body 10 are plugged and electrically connected, they can be connected to an external client through the plug connector 232. The plug connector 232 can be electrically connected to the external client in a plug-in matching manner.

[0054] As described above, the power terminal 20 may have no built-in control board 24 but have a wire 231, or may have no built-in control board 24 but have a plug connector 232, or may have a built-in control board 24 and a plug connector 232, and the number of plug pins in the plug connector 232 may also be three, four or other. A water pump body 10 can be adapted to a variety of power terminal connectors 20. When the client connector or control method changes, the power terminal connector 20 can be replaced to meet various application requirements and achieve compatibility of the water pump 100.

[0055] Combination Figure 3-Figure 14 As shown, both the second electrical connector 21 and the first electrical connector 11 are multiple, and the multiple first electrical connectors 11 correspond one-to-one to the multiple second electrical connectors 21. Specifically, the second electrical connector 21 and the first electrical connector 11 can be multiple, and the multiple first electrical connectors 11 correspond one-to-one to the multiple second electrical connectors 21. When assembling the water pump 100 and electrically connecting the water pump body 10 and the power supply terminal 20, the multiple first electrical connectors 11 and the multiple second electrical connectors 21 can be plugged and matched accordingly, thereby ensuring the normal operation of the water pump 100.

[0056] There may be three first electrical connectors 11, and the three first electrical connectors 11 correspond to the U phase, V phase and W phase of the stator winding 121, respectively. Correspondingly, there are also three second electrical connectors 21. Further, when the stator winding 121 is connected in star connection, there is a motor common end electrical connector, and when the stator winding 121 is connected in triangle connection, there is no motor common end electrical connector.

[0057] In some embodiments of the utility model, a first perforation is provided on the water pump body 10, and a second perforation is provided on the mounting cover 22, and the first perforation corresponds to the second perforation and is connected and fixed by a fastener. Specifically, by providing a first perforation on the water pump body 10 and a second perforation on the mounting cover 22, when the water pump 100 is assembled and the first electrical connector 11 and the second electrical connector 21 are plugged in and matched, the first perforation corresponds to the second perforation, and the fastener can penetrate the first perforation and the second perforation to connect and fix the mounting cover 22 and the water pump body 10, thereby realizing the connection between the power terminal 20 and the water pump body 10, further ensuring the stability of the electrical connection between the first electrical connector 11 and the second electrical connector 21, and improving the overall reliability of the water pump 100.

[0058] In other embodiments of the utility model, a first clamping portion is provided on the water pump body 10, and a second clamping portion is provided on the mounting cover 22, and the first clamping portion and the second clamping portion are clamped together. Specifically, by providing the first clamping portion on the water pump body 10 and providing the second clamping portion on the mounting cover 22, when the water pump 100 is assembled and the first electrical connector 11 and the second electrical connector 21 are plugged together, the first clamping portion and the second clamping portion can be clamped together to connect and fix the mounting cover 22 and the water pump body 10, so that the connection between the power terminal 20 and the water pump body 10 can be achieved, and the stability of the electrical connection between the first electrical connector 11 and the second electrical connector 21 can be further ensured, and the overall reliability of the water pump 100 can be improved.

[0059] In addition, a sealing gasket can be arranged between the mounting cover 22 and the water pump body 10, so as to improve the sealing between the mounting cover 22 and the water pump body 10 and prevent foreign matter from entering the interior of the water pump body 10 through the gap between the mounting cover 22 and the water pump body 10, thereby causing damage to the internal structure of the water pump body 10 or causing failure of the first electrical connector 11 and the second electrical connector 21, thereby improving the reliability of the water pump 100.

[0060] Furthermore, the side of the mounting cover 22 away from the water pump body 10 can be set as a metal part, which can improve heat dissipation and avoid heat accumulation inside the power terminal 20. In addition, the side of the mounting cover 22 close to the water pump body 10 and the side of the mounting cover 22 away from the water pump body 10 can be formed by welding, or by fastening with screws and sealing rings, which is not specifically limited here.

[0061] Combination Figure 2-Figure 4 As shown, a stator winding 121 is disposed in the water pump body 10 , and the stator winding 121 is connected to the first electrical connector 11 by butt welding; and / or the stator winding 121 is connected to the first electrical connector 11 by press fitting.

[0062] Specifically, when the water pump body 10 is working, the stator 12 is fixed and the rotor 16 rotates relative to the stator 12. The current in the stator winding 121 can determine the working state of the water pump 100. By electrically connecting the first electrical connector 11 to the stator winding 121, after the second electrical connector 21 of the power terminal 20 is plugged and electrically connected to the first electrical connector 11, the working state of the water pump 100 can be controlled.

[0063] Optionally, the stator winding 121 may be connected to the first electrical connector 11 by butt welding, which can ensure the stability and reliability of the connection between the stator winding 121 and the first electrical connector 11. The stator winding 121 may also be connected to the first electrical connector 11 by press-fitting, which can make the connection between the stator winding 121 and the first electrical connector 11 simpler and more convenient.

[0064] Combination Figure 1 , Figure 2 and Figure 8 As shown, the water pump body 10 may also include: a pump head 13, a watertight sleeve 14, a pump body 15, a sealing ring 19, a fastening screw 18 and a pump shaft 17. Among them, the pump head 13 can provide a volute flow channel so that the water pump 100 can perform energy conversion, and provide an installation interface for water-side assembly. The watertight sleeve 14 can separate the stator 12 from the rotor 16, realize the separation of the dry cavity and the wet cavity inside the water pump 100, and avoid the stator 12 short circuit caused by the coolant. The pump body 15 can provide support for the stator 12 and the watertight sleeve 14, and provide a fixed position for the power terminal 20. The sealing ring 19 can prevent the internal medium of the water pump 100 from flowing out and causing leakage, and prevent external impurities from entering the water pump 100. The fastening screw 18 can fix the pump head 13, the watertight sleeve 14, the pump body 15 and the sealing ring 19 together to provide a fastening force. The pump shaft 17 can provide support and limit for the rotation of the rotor 16. The pump shaft 17 can be injection molded in the waterproof sleeve 14, or the pump shaft 17 can be fixed in the waterproof sleeve 14 by pressing, assembling or welding, which is not specifically limited here.

[0065] In this way, when assembling the water pump body 10, the stator 12 can be pressed into the pump body 15 first, and then the sealing ring 19 and the water-blocking sleeve 14 can be installed. Then the rotor 16 can be installed on the pump shaft 17, the sealing ring 19 and the pump head 13 can be installed, and the fastening screws 18 can be installed to fasten and complete the assembly of the water pump body 10. Among them, the stator 12 can be axially positioned by the ribs on the pump body 15. There is a certain interference between the ribs and the iron core to ensure that it does not loosen after being pressed. In addition, there are protrusions on the stator 12, which are used to cooperate with the pump body 15 for circumferential positioning to ensure the stable installation of the stator 12 in the pump body 15.

[0066] The vehicle according to the utility model may include: the above-mentioned water pump 100. Specifically, by applying the water pump 100 to the vehicle, under the premise of ensuring that the water pump 100 meets the basic thermal management requirements of the vehicle, not only can the platform design of the vehicle be utilized, but also the maintenance cost of the vehicle can be reduced, thereby improving the user experience and enhancing the product competitiveness of the vehicle.
