[0034] In the embodiment, the bottom of the oil outlet pipe 3 is provided with a mounting hole, and the vertical shaft 6 penetrates the mounting hole through a sealing bearing and rotates, so that the smooth rotation of the vertical shaft 6 and the good sealing performance during rotation can be ensured.

[0035] In the embodiment, the top of the oil discharge pipe 3 is detachably mounted with a protective cover for shielding the driving assembly. The protective cover is used for dustproof and isolation protection of the driving assembly. The protective cover comprises a mesh cover 11, a supporting rod 12 and a connecting plate 13. The bottom of the mesh cover 11 is of an open structure. The vertical shaft 6, the secondary gear 7, the backing plate 8, the motor 9 and the main gear 10 are all located in the mesh cover 11.

[0039] Through the above structure, the working principle of the flow-adjustable new energy electric lubricating pump provided by the application is as follows:

[0040] During the working process of the electric lubricating pump main body 1, the lubricating oil is sucked from the oil inlet pipe 2, pressurized through the pump body, and then discharged outward through the oil outlet pipe 3 to provide lubrication for related parts of the new energy vehicle;

[0041] In the process of conveying lubricating oil, the actual flow of the lubricating oil in the oil outlet pipe 3 can be monitored in real time by using the flow sensor 15, and the oil pressure of the lubricating oil in the oil outlet pipe 3 can be monitored in real time by using the pressure sensor 16. The flow data monitored by the flow sensor 15 and the pressure data monitored by the pressure sensor 16 are transmitted to the controller 17, the controller 17 compares and analyzes the received flow data and pressure data with the preset standard value, if the flow or pressure deviates from the normal range, the controller 17 will control the motor 9 to rotate or operate according to the preset program, at this time, the output shaft of the motor 9 drives the main gear 10 to rotate, since the main gear 10 is engaged with the secondary gear 7, the secondary gear 7 rotates accordingly, and in turn drives the vertical shaft 6 to rotate, the bottom end of the vertical shaft 6 is fixedly connected with the baffle disc 5, so the baffle disc 5 also rotates, with the rotation of the baffle disc 5 in the oil outlet pipe 3, the flow area of the lubricating oil in the oil outlet pipe 3 changes, when the baffle disc 5 rotates to a small angle with the axis of the oil outlet pipe 3, the flow area of the lubricating oil increases, and the flow increases accordingly, when the angle increases, the flow area decreases, and the flow decreases, thereby realizing intelligent and accurate adjustment of the discharge flow of the lubricating oil, and reducing the consumption of electric energy;

[0042] In the process of conveying lubricating oil, if the lubricating oil pressure in the oil outlet pipe 3 monitored by the pressure sensor 16 exceeds the set threshold value, the controller 17 will detect that the flow is abnormal, at this time, the controller 17 will send a signal to the electromagnetic bypass valve 19 to open, in this way, the lubricating oil can be directly discharged back to the lubricating oil storage tank of the new energy vehicle through the bypass pipe 18, avoiding the rupture and leakage of the oil outlet pipe 3 due to the excessive oil pressure in the oil outlet pipe 3, ensuring the basic function of the lubricating system and improving the reliability and safety of the whole system.

[0043] The above are all preferred embodiments of the present application, and do not limit the protection scope of the present application, so that: all equivalent changes made according to the structure, shape, principle of the present application should be covered in the protection scope of the present application.
