Technical Field

[0001] This utility model relates to the field of electronic fuel pump technology, specifically to a novel automotive electronic fuel pump assembly. Background Technology

[0002] In current automotive fuel supply systems, fuel in the fuel tank needs to be continuously delivered to the engine through fuel lines. This process usually relies on a fuel pump installed inside the fuel tank to achieve power transmission.

[0003] However, while existing electronic fuel pumps filter impurities in the fuel after extraction, large particles accumulate on the filter screen over time. These impurities gradually clog the screen, leading to decreased filtration efficiency or even filter failure. This problem necessitates frequent filter replacement or cleaning, increasing maintenance costs and operational complexity, and also impacting the stability and continuity of the fuel supply system. Therefore, the technology still has room for improvement. Utility Model Content

[0012] Furthermore, the filter is equipped with an oil outlet connector, which is connected to the filter.

[0013] The beneficial effects of adopting the above-mentioned further solutions are:

[0014] The fuel outlet connector serves as the output channel for filtered clean fuel and can be connected to the fuel supply line of the car engine to deliver the filtered fuel.

[0015] Furthermore, a sealing cap is threaded onto the side end face of the filter, and a sealing ring is fitted onto the inner wall of the sealing cap.

[0016] The beneficial effects of adopting the above-mentioned further solutions are:

[0017] The threaded sealing cap can be disassembled and installed, facilitating the maintenance, cleaning, or replacement of internal filter components; the inner sealing ring enhances sealing performance and effectively prevents fuel leakage from the connection between the sealing cap and the filter during filtration and delivery.

[0018] Furthermore, a mounting base is fixed to the bottom end face of the filter, and the mounting base is connected to the electronic fuel pump body by mounting bolts.

[0035] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0036] Please see Figures 1 to 4 As shown, the embodiments provided by this utility model are as follows:

[0037] A novel automotive electronic fuel pump assembly includes an electronic fuel pump body 1, on which a filter 3 is provided;

[0038] A filter screen 4 is fitted inside the filter 3. A connecting block 401 is fixedly installed on the inner wall of the filter screen 4. A connecting rod 5 is provided inside the filter screen 4. A metal spring piece 501 is installed on the connecting rod 5. The connecting rod 5 is connected to the connecting block 401 by threads.

[0039] The electronic fuel pump body 1 is equipped with an inlet connector 101 and a delivery pipe 102. The end of the delivery pipe 102 facing away from the electronic fuel pump body 1 is installed inside the filter 3. The inlet connector 101 provides an interface for fuel to enter the electronic fuel pump body 1, which is convenient for connecting to the fuel supply line of the car's fuel tank. The delivery pipe 102 can guide the fuel delivered by the electronic fuel pump body 1 into the filter 3, forming a continuous process of "fuel inlet-delivery-filtration".

[0040] The filter 3 is equipped with an oil outlet connector 301, which is connected to the filter 3. The oil outlet connector 301 serves as the output channel for the filtered clean fuel and can be connected to the fuel supply line of the car engine to realize the delivery of the filtered fuel.

[0041] A sealing cover 302 is threadedly installed on the side end face of the filter 3. A sealing ring is fitted on the inner wall of the sealing cover 302. The threaded sealing cover 302 can be disassembled and installed, which facilitates the maintenance, cleaning or replacement of the internal components of the filter 3. The sealing ring on the inner wall can enhance the sealing performance and effectively prevent fuel from leaking from the connection between the sealing cover 302 and the filter 3 during filtration and transportation.

[0042] The bottom end face of the filter 3 is fixed with a mounting base 2. The mounting base 2 is connected to the electronic fuel pump body 1 by mounting bolts 201. The cooperation between the mounting base 2 and the mounting bolts 201 allows the filter 3 to be installed on the electronic fuel pump body 1.

[0043] Several metal springs 501 are arranged in a circular array relative to the center of the connecting rod 5, and through holes 502 are provided on the metal springs 501. The several metal springs 501 arranged in a circular array can form sufficient and uniform contact with the fuel when the fuel enters the filter 3 through the delivery pipe 102, so that the force distribution of the fuel impacting the springs is more reasonable. When the fuel impacts the metal springs 501, the springs vibrate and drive the filter screen 4 to vibrate synchronously through the connecting rod 5, which can shake off large particles of debris attached to the mesh of the filter screen 4 in time, effectively preventing the mesh from being blocked and ensuring that the filtration channel is unobstructed. At the same time, the through holes 502 on the metal springs 501 do not obstruct the flow of fuel.

[0044] Furthermore, the metal spring 501 can be made of stainless steel. It has good elasticity, can deform appropriately and return to its original position under fuel impact, and meet vibration requirements; at the same time, stainless steel is resistant to fuel corrosion and can maintain structural stability and performance over a long period of time.

[0045] Working principle: Fuel enters the electronic fuel pump body 1 through the fuel inlet connector 101 on the electronic fuel pump body 1. The fuel inlet connector 101 is connected to the fuel supply line of the vehicle's fuel tank, providing a channel for fuel to enter.

[0046] The electronic fuel pump body 1 delivers fuel to the delivery pipe 102. One end of the delivery pipe 102 away from the electronic fuel pump body 1 is installed inside the filter 3, and the fuel is introduced into the filter 3 through the delivery pipe 102.

[0047] The fuel entering the filter 3 first comes into contact with the metal spring 501 on the connecting rod 5. Several metal springs 501 arranged in a ring array vibrate under the impact of the fuel, and the vibration is transmitted to the filter screen 4 through the connecting rod 5.

[0048] After passing through the through holes 502 on the metal spring 501, the fuel flows to the filter screen 4. The filter screen 4 intercepts and filters large particulate impurities in the fuel, and at the same time, the vibration shakes off the debris attached to the mesh, preventing the mesh from becoming clogged.

[0049] The filtered clean fuel is output through the oil outlet connector 301 on the filter 3. The oil outlet connector 301 is connected to the fuel supply line of the car engine to deliver the clean fuel to the engine.

[0050] A sealing cap 302 is threadedly installed on the side end face of the filter 3. The sealing ring on the inner wall of the sealing cap 302 ensures the sealing performance of the filter 3 and prevents fuel leakage. The bottom end face of the filter 3 is connected to the electronic fuel pump body 1 through the mounting base 2 and mounting bolts 201 to ensure the stability of the entire assembly structure.
