[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Example

[0024] Reference Figures 1-3 An electronic oil pump with an installation structure includes a pump housing 1, a motor rotor inside the pump housing 1, an oil chamber 6 at one end of the pump housing 1, an outer rotor 7 inside the oil chamber 6, and an inner rotor 8 inside the outer rotor 7. The motor rotor and the inner rotor 8 are keyed together. An installation cover 9 is fixed to one end of the pump housing 1 by bolts. Multiple ends of the installation cover 9 are integrally formed with first connecting ears 11. The first connecting ears 11 are provided with first mounting holes 10. Bolts are inserted into the first mounting holes 10 to facilitate the external fixed installation of the electronic oil pump. Multiple reinforcing ribs 12 are integrally formed on one side of the outer wall of the installation cover 9. The reinforcing ribs 12 enhance the robustness of the installation cover 9 and extend the service life of the electronic oil pump. A first oil inlet hole 13 and a first oil outlet hole 14 are provided on one side of the installation cover 9.

[0025] One end of the pump housing 1 is fixed with an isolation cover plate 2 by bolts. One end of the isolation cover plate 2 is fixed with a circuit board housing 3 by bolts. The circuit board body 5 is fixed inside the circuit board housing 3 by bolts. One end of the circuit board housing 3 is fixed with an end cap 4 by bolts, thereby sealing the circuit board housing 3.

[0026] The working principle of this embodiment is as follows: When in use, the bolt is inserted into the first mounting hole 10, which facilitates the external fixed installation of the electronic oil pump. Then, the reinforcing rib 12 strengthens the rigidity of the mounting cover 9 and extends the service life of the electronic oil pump.

[0027] The interaction between the rotating magnetic field generated by the motor stator inside the electronic oil pump and the motor rotor conductors creates a rotating magnetic field when three-phase AC power is applied to the motor stator windings. This rotating magnetic field cuts the motor rotor conductors, and according to the principle of electromagnetic induction, an induced electromotive force and current are generated in the motor rotor conductors. Since the motor rotor conductors are closed, the current in the magnetic field is subjected to an electromagnetic force. This force causes the motor rotor to rotate in the direction of the rotating magnetic field. The motor rotor drives the inner rotor to rotate, and the inner rotor drives the outer rotor 7 to rotate, with the inner rotor rotating faster than the outer rotor 7. Multiple mutually enclosed working chambers are formed between the inner and outer rotors. Each working chamber is connected to the first oil inlet 13 when it is at its smallest. Subsequently, the volume increases, forming a vacuum and drawing in engine oil. As the inner rotor continues to rotate, the volume of the working chamber decreases, and the oil pressure increases. When the working chamber is connected to the first oil outlet 14, engine oil is squeezed out. Example

[0028] Reference Figures 4-5An electronic oil pump with an installation structure includes a connecting plate 15 integrally formed on the circumferential outer wall of a pump housing 1. The connecting plate 15 has multiple second connecting ears 16 integrally formed on the circumferential outer wall. The second connecting ears 16 are provided with second mounting holes 17. Bolts are inserted into the second mounting holes 17 to facilitate built-in fixed installation. A sealing ring 18 is snapped onto one side of the connecting plate 15. The sealing ring 18 is sleeved on the circumferential outer wall of the pump housing 1. The sealing ring 18 improves the sealing between the connecting plate 15 and the connecting parts. A pump cover 19 is fixed to one end of the pump housing 1 by bolts. A second oil inlet hole 20 and a second oil outlet hole 21 are provided on one side of the pump cover 19.

[0029] The working principle of this embodiment is as follows: When in use, the bolt is inserted into the second mounting hole 17 to facilitate built-in fixed installation. Then, the sealing ring 18 improves the sealing between the connecting plate 15 and the connecting parts.

[0030] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
