Description

Technical Field

[0001] This utility model relates to the field of fuel supply, specifically to a fuel pump assembly fuel supply module. Background Technology

[0002] The fuel pump assembly is a crucial component of a car's fuel system. It is responsible for delivering fuel from the fuel tank to the engine and ensuring that the fuel pressure remains stable within the appropriate range. It has a critical impact on the normal operation, performance, and fuel economy of the engine.

[0003] Chinese utility model patent publication number "CN205423013U" discloses an intelligent fuel pump assembly, including a fuel pump, a bracket, and an assembly housing. An intelligent control module is provided on the outside of the fuel pump. The intelligent control module includes a flow sensor module and an adjustable motor driver. The adjustable motor driver is communicatively connected to the flow sensor module. The flow change signal output by the flow sensor module is transmitted to the adjustable motor driver. The adjustable motor driver analyzes the flow change signal, determines the change in the amount of fuel used by the car engine, and outputs the optimal amount of fuel according to the needs of the car engine.

[0004] However, the fuel supply module of the aforementioned fuel pump assembly still has the following drawbacks:

[0005] First, the flow sensor identifies changes in the amount of fuel in the tank to control the speed of the motor. During operation, the fuel will slosh around in the tank, and the fuel level will not be uniform. The flow sensor has low recognition accuracy and slow dynamic response. In addition, the flow sensor needs to be installed inside the tank, making replacement and maintenance more complicated.

[0006] Second, the measuring element of the flow sensor is in direct contact with the fuel in the tank. Impurities or gum deposits in the fuel can easily lead to measurement errors or sensor malfunctions, resulting in reduced accuracy of fuel output control.

[0007] Third, the fuel pump assembly usually integrates the filter and the fuel pump. The connectors of the filter and the fuel pump are directly electrically connected to the connectors on the flange. The connectors need to be wrapped around or placed directly in the gap. During use, the connectors are prone to shaking on the fuel pump assembly. The connection between the connectors and the connectors may become loose due to shaking. Furthermore, the random placement of the connectors can affect the disassembly or installation process.

[0008] Therefore, it is necessary to improve upon the aforementioned shortcomings. Utility Model Content

[0054] The flange 1 has a surrounding edge 15 at the oil outlet pipe 22. The surrounding edge 15 has several clips 151 for fastening the filter. Each clip 151 has a corresponding groove 152 on both sides. The clips 151 provide a tight connection point between the fuel filter and the fuel supply module, ensuring a secure installation of the fuel filter and preventing it from loosening due to vibration or external force during vehicle operation, thus ensuring the stability and safety of the fuel supply system. Furthermore, the clearance fit between the surrounding edge 15 and the filter enhances the structural strength around the oil outlet pipe 22 and also serves as a guide and positioner, making filter installation more convenient and accurate. The cooperation between the clips 151 and the grooves 152 effectively disperses the connection force between the filter and the fuel pump assembly, preventing damage caused by excessive localized force. Simultaneously, the grooves 152 facilitate the fastening and disassembly of the clips 151, improving maintenance and replacement efficiency.

[0055] A connector 16 is provided around the perimeter of the circumference of the flange 15. The connector 16 has a guide strip 161 on the flange 15, and the end of the guide strip 161 has a wedge-shaped portion 162 for guiding insertion. The guide strip 161 and the wedge-shaped portion 162 provide high positioning accuracy for the filter installation and effectively control vibration and noise of the fuel pump assembly during operation. Furthermore, the guide strip 161 allows for quick insertion and removal of the flange 1, making installation more precise and convenient. At the same time, the wedge-shaped portion 162 ensures an anti-dislodgement effect, further improving the reliability of the flange 1 connection.
