Oil pump controller and oil pump bracket assembly

Abstract

The invention discloses an oil pump controller and an oil pump bracket assembly integrated with the oil pump controller. The oil pump controller comprises a shell, a PCB and a flange connecting head, wherein an insert needle is fixed on the outer wall of one surface of the shell in an injection molding manner, and one end of the insert needle stretches out of the outer wall of the shell to form a controller electric plug; the PCB is vertically placed in a cavity of the shell; the flange connecting head is arranged at the lower end of the bottom surface of the shell and can be fixedly matched and assembled with a flange; and the flange is provided with a groove, a mounting hole is formed in the bottom of the groove, and the flange connecting head of the oil pump controller is clamped into the mounting hole. The oil pump controller is small in size, a wiring harness and an electrical plug between the oil pump controller and an oil pump assembly can be saved, and after-sale replacement of the oil pump controller is facilitated.

Description

technical field [0001] The invention relates to an automobile oil supply device, in particular to an oil pump controller and an oil pump bracket assembly. Background technique [0002] In the current automotive fuel pump control system that supplies fuel on demand, the separate fuel pump controller such as figure 1 As shown, the oil pump controller 2 is a part independent of the oil pump assembly 1, the oil pump controller 2 communicates with the engine controller 4, and is separately installed on the fuel tank or somewhere on the chassis. This separate design requires a separate complete oil pump controller 2 housing and its fixed chassis bracket parts, and also requires a complex wiring harness 3 with multiple pins (pins) for connecting the oil pump controller 2 and the oil pump assembly. Into 1, it not only takes up the limited space of the chassis, but also increases the cost of parts. [0003] Flange integrated oil pump controller such as figure 2 As shown, the oil ...

AI Technical Summary

Problems solved by technology

This separate design requires a separate complete oil pump controller 2 housing and its fixed chassis bracket parts, and also requires a complex wiring harness 3 with multiple pins (pins) for connecting the oil pump controller 2 and the oil pump assembly. 1, not only takes up limited space on the chassis, but also increases the cost of parts

[0003] Flange integrated oil pump controller such as figure 2 As shown, the oil pump controller 2 is integrated on the flange 10 of the oil pump assembly 1, but it cannot be disassembled and replaced after sales, and the area of ​​the oil pump controller 2 occupies even more than 60% of the layout space of the flange 10, making it difficult to re-arrange. other parts

Because the oil pump controller 2 itself needs to adapt to the space arrangement on the flange 10, its body is usually designed as an irregular shape, such as an irregular sector, which leads to a sharp increase in the cutting cost and chip placement cost of the oil pump controller 2 circuit board.
