Description

Technical Field

[0001] This utility model relates to the field of vehicle-mounted oil pump technology, and in particular to a vehicle-mounted oil pump that is easy to assemble. Background Technology

[0002] With economic development and the gradual improvement of people's living standards, automobiles have become one of the preferred means of transportation for the general public. The automotive industry is developing rapidly, and as vehicle performance moves towards greater safety, reliability, stability, environmental protection, and energy conservation, a complete set of actuators is needed to ensure the stable operation of the vehicle's powertrain. Therefore, various actuators with electric motors are widely used in automotive powertrains, including hydraulic actuators, gear shift actuators, and brake boosters.

[0003] To ensure the cooling and lubrication of various engine components, an electronic oil pump is needed to power the oil circulation. The electronic oil pump is powered by an internal motor controlled by its own controller system, which drives the impeller (inner and outer rotors) to circulate the oil, thereby cooling and lubricating the relevant components. Currently, the new electronic oil pump consists of a controller, a motor, and inner and outer rotors of the pump head. To ensure the stability of the connection between various structures and the stable operation of the product, as well as to meet the heat dissipation requirements, there are high requirements for the overall structural design. The current vehicle oil pump structure is relatively simple and cannot meet higher practical needs, so there is a need for improvement. Utility Model Content

[0004] This utility model provides an easy-to-assemble vehicle-mounted oil pump with an integrated injection molding process for the connector lead wire and stator, ensuring the stability of the connector and stator, optimizing the assembly of the controller, and meeting higher practical requirements. It solves the technical problems of existing vehicle-mounted oil pumps having a relatively simple structure, low assembly efficiency, and an overall structure that cannot be further optimized to meet higher usage requirements.

[0005] The above-mentioned technical problem of this utility model is solved by the following technical solution: a vehicle-mounted oil pump that is easy to assemble, comprising an electronic oil pump consisting of a controller, a motor, a pump head, a rotor, and a stator. The stator of the electronic oil pump is encased in a plastic assembly, and a connector lead wire is integrally injection molded on the assembly. A connector is provided in the middle of the assembly, and a PCBA that mates with the connector is provided at the bottom of the controller cover. The stator and connector lead wire of this utility model are integrally injection molded, which improves their stability. During assembly, the stator is first pressed onto the electronic oil pump housing, and the assembly outside the stator mates with the oil pump housing, which greatly improves the stability of the stator during assembly. Then, the PCBA is assembled onto the controller cover, and finally the two are assembled together. During assembly, the connector passes through the middle of the annular PCBA, and the pins are led out from the surrounding area.

[0006] Preferably, the assembly is fitted and assembled with the electronic oil pump housing. The stator and connector lead wires of this invention are integrally injection molded, improving their stability. During assembly, the stator is first press-fitted onto the electronic oil pump housing, and the assembly outside the stator mates with the oil pump housing, greatly improving the stability of the stator during assembly.

[0007] Preferably, the PCBA is a ring-shaped structure. The ring-shaped structure of the PCBA in this invention allows for better control of the assembly process, facilitates observation of the PCBA's condition, and results in better assembly performance.

[0008] Preferably, the PCBA is directly mounted on the controller cover. First, the stator is mounted into the electronic oil pump, then the annular PCBA is directly mounted onto the controller cover, and then the two are assembled together.

[0009] Preferably, the connectors protrude from the central circular hole of the PCBA, with pins extending from the surrounding area. First, the stator is assembled into the electronic oil pump, then the PCBA is assembled onto the controller cover, and finally, the two are assembled together. During assembly, the connectors protrude from the center of the annular PCBA, with pins extending from the surrounding area.

[0010] Therefore, the vehicle-mounted oil pump of this utility model, which is easy to assemble, has the following advantages: it is easy to assemble, the connector lead wire and the stator are integrally injection molded, ensuring the stability of the connector and the stator, optimizing the assembly of the controller, and can meet higher practical requirements.
