Problems solved by technology

The above-mentioned welding or crimping connection method used between the circuit board and the motor stator is difficult to disassemble after connection. When the motor of the electric oil pump or its circuit board fails, it is impossible to determine whether the faulty part is the motor part or the drive device part or the Therefore, once the electrical performance of the electric oil pump is detected to be poor, usually the motor + circuit board part of the entire electric oil pump has to be scrapped.

Abstract

The invention relates to a motor oil pump. The motor oil pump comprises a mechanical part and a control part detachably connected with the mechanical part. The mechanical part comprises a stator and arotor matched with the stator; the control part comprises an end cover with an inner cavity, a circuit board located in the inner cavity of the end cover and an electric connection port used for being connected with an external power source and arranged on the outer wall of the end cover. The circuit board is detachably and electrically connected with the stator. According to the motor oil pump,the electric connection port and the end cover part which are complex in structure and prone to causing poor manufacturing are subjected to injection molding together, the motor stator part and the motor shell part are subjected to injection molding together, and when the motor oil pump breaks down, the motor oil pump can be detached and the mechanical part and the control part are detected, replaced and maintained respectively.

Description

technical field [0001] The invention relates to an electric motor oil pump. Background technique [0002] In the prior art, the motor stator of an injection-molded electric motor oil pump is integrally molded together with the motor housing. In addition to the connecting wires of the motor stator, there are also electrical connection ports on the housing part. These electrical connection parts The structure is complex, and it is easy to produce poor manufacturing during the injection molding process. Once a defective product is produced, the injection molded part will be scrapped as a whole. waste. [0003] In addition, the electric motor oil pump device has a control device with a circuit board, and the circuit board needs to be connected with the wires of the motor stator. The existing technology mainly adopts the fixed connection method of leading out the wire and welding or crimping the circuit board, and then fixes the circuit board on the injection molded stator thro...
