Description

Technical Field

[0001] This utility model relates to the field of automotive fuel filtration technology, specifically a fuel filter assembly with an electric fuel pump. Background Technology

[0002] In automotive fuel supply systems, fuel filters are key components that ensure reliable engine operation. Their core function is to filter impurities, water, and other contaminants from the fuel, preventing downstream engine components such as fuel injectors and fuel pumps from failing due to wear or blockage, thereby ensuring stable engine power output and reducing emissions.

[0003] The filter and the oil pump need to be installed separately, involving the assembly of multiple sets of fixed brackets and pipeline interfaces. This not only increases the complexity of the vehicle assembly process, but also requires more installation space, which goes against the current trend of compact design of automobile chassis. Furthermore, the two sets of components need to be disassembled separately during later maintenance, which is cumbersome and time-consuming, increasing the user's maintenance costs. Therefore, improvements are needed. Utility Model Content

[0004] The purpose of this invention is to provide a fuel filter assembly with an electric fuel pump to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a fuel filter assembly with an electric fuel pump, comprising a mounting plate, a connecting frame fixedly connected to the bottom left side of the mounting plate, a fixing frame fixedly connected to the bottom right side of the mounting plate, a filtering mechanism provided at the bottom of the mounting plate, and a connecting mechanism provided at the bottom of the mounting plate;

[0006] The connecting mechanism includes a mounting bracket disposed on the front of a fixed bracket. A bolt is threadedly connected to the inner side of the mounting bracket, and the bolt is threadedly connected to the inner side of the fixed bracket. A delivery pump body is fixedly connected to the inner side of the connecting bracket. A connecting hose is fixedly connected to the back end of the delivery pump body. A tube is fixedly connected to the left side of the front of the connecting hose. A fixed cylinder is inserted into the tube. A connecting plate is fixedly connected to the outer side of the tube. Fixed screws are slidably connected to the left and right sides of the connecting plate. Nuts are threadedly connected to the outer side of the fixed screws.

[0007] Preferably, the nut is disposed on the back end of the connecting plate, and the front of the nut is in contact with the front of the connecting plate. The nut can be used to fix the connecting hose and the insert to the back end of the filter housing.

[0008] Preferably, the connecting plate has an insertion hole on its inner side that corresponds to the position of the fixing screw, and the fixing screw is slidably connected to the inner side of the insertion hole. Through the insertion hole, the connecting plate can slide around the fixing screw to initially limit the insertion cylinder and fix the insertion cylinder to the outside of the fixing cylinder.

[0009] Preferably, the filtration mechanism includes a filter cartridge housing fixedly connected to the bottom of the connecting frame, an oil outlet pipe fixedly connected to the front of the filter cartridge housing, a buffer plate fixedly connected to the front of the inside of the filter cartridge housing, a guide plate fixedly connected to the front of the buffer plate, a paper filter element fixedly connected to the front of the guide plate, a guide cylinder fixedly connected to the front of the paper filter element, and a filter plate fixedly connected to the front of the guide cylinder.

[0010] Preferably, there are two fixing screws, which are respectively fixedly connected to the back end of the filter housing. The fixing screws and nuts work together to limit the position of the connecting plate, making the connecting hose more stable when conveying oil.

[0011] Preferably, the fixed cylinder is fixedly connected to the middle of the back end of the filter housing, and the front of the insert and the connecting plate are in close contact with the back end of the filter housing, so that fuel is not easily leaked when the insert and the fixed cylinder are connected.

[0012] Compared with the prior art, the present invention provides a fuel filter assembly with an electric fuel pump, which has the following advantages:

[0013] 1. In the connection mechanism of this fuel filter assembly with electric fuel pump, the mounting bracket is connected to the fixing bracket by bolts and threads, which can quickly fix the device to the external structure. The connection between the pump body and the filter housing is positioned by inserting the insert and fixing cylinder, and then locked by the cooperation of the connecting plate, fixing screw and nut. The double fixing method not only simplifies the installation process, but also ensures a tight connection and effectively prevents the parts from loosening or falling off due to vibration during use.

[0014] 2. In this fuel filter assembly with an electric fuel pump, the buffer plate in the filtration mechanism slows down the flow rate of fuel entering the filter housing, preventing impact damage to the filter element. The guide plate and guide cylinder guide the fuel to flow orderly through the paper filter element and filter plate, extending the contact time between the fuel and the filter components. This allows the paper filter element to fully intercept fine impurities, and the filter plate further assists in filtration. The dual filtration structure significantly improves fuel cleanliness and effectively protects downstream equipment such as engines. Attached Figure Description
