Description

Technical Field

[0001] This invention relates to the field of sealed electronic oil pump technology, specifically to a high-pressure sealed electronic oil pump and method that is easy to install. Background Technology

[0002] An electric oil pump is an electric motor-driven oil pump used to maintain oil pressure and lubricate automatic transmissions / continuously variable transmissions during engine stop operations, such as when starting and stopping a vehicle. For hybrid vehicles, this product provides oil pressure for transmission operation in electric mode, while for electric vehicles, it has cooling and lubrication functions. The electric oil pump mainly consists of a housing, circuit board, stator, and rotor.

[0003] Electronic oil pumps need to be connected to oil pipelines during operation. For example, patent number 201810519275.4 published on the China Patent Network, entitled "Electronic Oil Pump," includes a pump housing, a first rotor assembly, a stator assembly, a second rotor assembly, and an electronic control board. The pump housing forms the pump cavity. The electronic oil pump includes a support member, at least a portion of which is disposed between the stator assembly and the electronic control board. The electronic oil pump includes connecting terminals. The support member includes a main body. The connecting terminal includes a main body, a first connecting part, and a second connecting part. The main body is disposed between the first connecting part and the second connecting part. At least a portion of the main body is tightly fitted to the main body or at least a portion of the main body is injection molded to the main body. At least a portion of the first connecting part extends out of the main body, and at least a portion of the second connecting part extends out of the main body. At least a portion of the first connecting part of the connecting terminal is connected to the stator assembly, and at least a portion of the second connecting part of the connecting terminal is connected to the electronic control board. This arrangement helps to improve the reliability of the connection between the connecting terminal and the stator assembly and the electronic control board.

[0020] 6. By setting a rotating wheel, the present invention makes it easier for users to rotate the bidirectional screw, which can increase the contact area between the bidirectional screw and the hand, and at the same time reduce the difficulty of operating the bidirectional screw.

[0021] 7. By setting a rubber sleeve, the present invention can protect the push rod, reduce the wear caused by the push rod and the transmission plate during contact friction, and at the same time facilitate the application of pressure by the push rod. Attached Figure Description
