Abstract
The utility model provides an automobile electronic water pump which comprises an impeller, wherein a spiral groove is formed in the outer side of the impeller, and the rotation direction of the spiral groove is opposite to that of a rotor. When the electronic water pump works, because the pressure in the pump cavity is higher than the pressure of the water inlet of the impeller, liquid in the pump cavity flows from a high-pressure area to a low-pressure area through a gap of the circumferential surface outside the impeller, so that volume leakage loss and hydraulic loss are caused. Compared with the traditional impeller adopting a semi-closed structure, the impeller provided by the utility model can reduce the volume leakage loss and the hydraulic loss, improve the suction performance of the impeller, and improve the performance and efficiency of the impeller.

Technical Field
The utility model relates to the technical field of water pumps, in particular to an automobile electronic water pump.
Background
The new energy automobile generally refers to an automobile which uses some unconventional automobile fuel as a power source or uses the conventional automobile fuel but is driven by a novel vehicle-mounted power device. The new energy automobile is an advanced technology industry combining technologies such as a power control technology and a driving technology of the automobile, and the formed automobile is provided with an advanced technology, a novel technology and a novel structure.
The automobile water pump is a main component of an automobile and plays an important role in an automobile heat management system. The water pump used by the traditional fuel vehicle is a mechanical water pump, and is characterized in that the water pump is driven by an engine gear train to rotate and cannot be started or stopped as required, particularly in cold areas in winter, the water pump works along with the engine after the engine is started, the heat engine time of the engine is prolonged, and resource waste is caused. In recent years, energy vehicles are rapidly developed under the great support of China, new energy vehicles are driven by battery packs, heat generated by electric elements on the vehicles during working also needs to be cooled, and therefore electronic water pumps are generated. The electronic water pump can be started and stopped as required, and is more intelligent.
Chinese patent document CN 103256242B (application No. 201310160734.1) discloses an electronic pump for an automobile, which comprises a pump casing, a pump head, a housing, a rotor and a stator, wherein one end of the rotor is provided with an impeller, the impeller has a water inlet side and a water outlet side, the water inlet side faces a water inlet of the pump head, the water outlet side faces a water outlet of the pump head, and the impeller is a semi-open impeller without a leakage-proof design. Therefore, the volume loss and the hydraulic loss of the water pump are large in the operation process of the water pump, so that the pump lift and the hydraulic efficiency of the water pump are low, and the effective utilization rate of the battery of the new energy automobile is influenced.
SUMMERY OF THE UTILITY MODEL
The technical problem to be solved by the utility model is as follows: the technical problems that the volume loss and the hydraulic loss of a traditional automobile electronic water pump are large, and therefore the lift and the hydraulic efficiency of the electronic water pump are low are solved.
The utility model provides an automobile electronic water pump which comprises an impeller, wherein a spiral groove is formed in the outer side of the impeller, and the rotation direction of the spiral groove is opposite to that of a rotor.
When the electronic water pump works, because the pressure in the pump cavity is higher than the pressure of the water inlet of the impeller, liquid in the pump cavity flows from a high-pressure area to a low-pressure area through a gap of the circumferential surface outside the impeller, so that volume leakage loss and hydraulic loss are caused. Compared with the traditional impeller adopting a semi-closed structure, the impeller provided by the utility model can reduce the volume leakage loss and the hydraulic loss, improve the suction performance of the impeller, and improve the performance and efficiency of the impeller.
Because traditional motor back lid material is iron or plastics, and heat dispersion is relatively poor, so further improve and solve this problem, it is specific, still include the motor, the lid material is the aluminum alloy behind the motor.
In order to explain the concrete structure of the stator assembly in the motor, in the scheme, the motor stator is provided with an integrally formed central shaft, and the rotor is sleeved with the central shaft.

The utility model is further illustrated with reference to the following figures and examples.
FIG. 1 is a schematic structural view of the present invention;
in the figure: 1. an impeller; 2. a helical groove; 3. a rotor; 4. a bearing; 5. a water inlet; 6. a water outlet; 7. a stator; 8. a central shaft; 9. a motor; 10. a rear cover; 11. a controller cavity; 12. a controller; 13. a seal ring; 14. a pump chamber; 15. a volute.
Detailed Description
The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic views illustrating only the basic structure of the present invention in a schematic manner, and thus show only the constitution related to the present invention.
As shown in fig. 1, the present invention is an automotive electronic water pump, which includes a motor 9, the motor 9 includes a stator 7, a rotor 3 and a central shaft 8 located at the center of the stator 7, the stator 7 and the central shaft 8 are installed on the casing of the motor 9 by injection molding. The rotor 3 comprises a bearing 4 sleeved with the central shaft 8 and an impeller 1 sleeved with the bearing 4, so that the impeller 1 is rotatably connected.
The outer side of the blade of the impeller 1 is provided with a spiral groove 2, and the rotation direction of the spiral groove 2 is opposite to that of the rotor 3.
The lower end of the machine shell is provided with a rear cover 10 which is sealed by a sealing ring 13. The rear cover 10 is made of aluminum alloy, and has better heat dissipation performance compared with the conventional rear cover made of iron or plastic.
A controller cavity 11 is formed between the rear cover 10 and the casing, a controller 12 is installed in the controller cavity 11, the controller 12 is fixed with a buckle through a positioning pin of the casing by injection molding, and the controller 12 is electrically connected with the motor 9 and forms a brushless motor drive.
The upper end of the machine shell is provided with a volute 15, and the upper end of the volute 15 is provided with a water inlet 5. The lower end of the volute 15 is covered on the impeller 1, and forms a pump cavity 14 together with the stator 7 and the impeller 1. The pump chamber 14 is provided with a water outlet 6.
When the electronic water pump works, because the pressure in the pump cavity 14 is higher than the pressure of the water inlet 5 of the impeller 1, liquid in the pump cavity 14 can flow from a high-pressure area to a low-pressure area through a gap on the circumferential surface outside the impeller 1, so that volume leakage loss and hydraulic loss are caused, the spiral groove 2 is arranged, so that the spiral groove 2 can also convey a certain amount of liquid from the water inlet 5 to the pump cavity 14 in the rotating process of the impeller 1 on the rotor 3, the flow conveyed by the spiral groove 2 is equal to the leakage amount, zero leakage is realized, and the impeller 1 is sealed. Compared with the traditional impeller 1 adopting a semi-closed structure, the utility model can reduce the volume leakage loss and the hydraulic loss, improve the suction performance of the utility model and improve the performance and the efficiency of the utility model.
