Description

Technical Field

[0001] This utility model relates to the field of fuel pump technology, specifically to a modular brushless fuel pump. Background Technology

[0002] The brushless electric fuel pump includes a controller and a pump body. The controller obtains power from the ECU and converts the DC regulated power into a three-phase alternating current through its internal MOSFET. This current is then transmitted to the windings on the stator inside the pump body, forming an electromagnetic induction. This induction is then transmitted to the permanent magnet on the rotor inside the pump body, causing the rotor to run. This converts electrical energy into kinetic energy, which drives the turbine inside the pump body to rotate at high speed, thereby achieving fuel pumping.

[0003] For example, a brushless fuel pump with publication number "CN212318194U" includes a housing, a stator plastic-coated body, and a rotor assembly. The stator plastic-coated body has a hollow structure, and the rotor assembly is located inside the stator plastic-coated body. The stator plastic-coated body is located inside the housing. The rotor assembly includes a shaft and a magnet. One end of the stator plastic-coated body is connected to a power supply connector, and the other end of the stator plastic-coated body is connected to an oil inlet. The stator plastic-coated body includes stator silicon steel sheets, enameled wire windings, and a plastic shell arranged sequentially from the inside out. The terminals of the enameled wire windings are connected to the power supply connectors, and the terminals of the enameled wire windings are spot-welded to the power supply connectors.

[0004] However, the existing interfaces of the brushless fuel pumps mentioned above, namely the inlet and outlet specifications, are fixed, resulting in poor compatibility when adapting to different vehicle models or systems, and users cannot change the interface as needed. Summary of the Invention

[0005] The technical problem to be solved by this utility model is to provide a brushless fuel pump with modular interface that can be adapted to different vehicle models, addressing the shortcomings of the prior art.

[0007] By adopting the above technical solution: Compared with the existing technology where the interface specifications are fixed and cannot be adapted to different vehicle models, this utility model, through the first disassembly structure and the second disassembly structure, allows the oil outlet and oil inlet interfaces to be detachably set on the oil pump cover and pump body, thereby adapting to different vehicle models and realizing the modular design of the interface. Users only need to replace the corresponding interface as needed and install it on the oil pump cover and pump body, thereby improving compatibility.

[0008] A further feature of this invention is that: the oil outlet end is provided with a first mounting post, the middle part of the first mounting part is provided with a first mounting groove for the first mounting post to connect, the outer wall of the first mounting post is provided with a first external thread, the side wall of the first mounting groove is provided with a first internal thread adapted to the first external thread, and the oil outlet is provided with an oil outlet channel.

[0009] The above technical solution allows for quick assembly and disassembly of the oil outlet interface via a first mounting post. This connection between the first mounting post and the first mounting groove is simple and easy for users to replace.

[0010] A further feature of this invention is that: a second mounting portion extends outward from the bottom of the pump body; a second mounting groove is provided in the middle of the second mounting portion; a second through hole communicating with the pump body is opened at the bottom of the second mounting groove; a second mounting post is provided at the end of the oil inlet interface that can be connected to the second mounting groove; a second external thread is provided on the outer wall of the second mounting post; a second internal thread adapted to the second external thread is provided on the side wall of the second mounting groove; and an oil inlet channel is provided through the oil inlet interface.

[0011] The above technical solution allows for quick assembly and disassembly of the oil inlet interface via a second mounting post. This simple structure facilitates easy replacement by connecting the second mounting post to the second mounting groove.

[0012] A further feature of this invention is that an integrally formed mounting ring is provided in the middle of the outer wall of the pump body, mounting blocks are symmetrically provided on both sides of the mounting ring, and mounting holes are provided through the mounting blocks.

[0013] The above technical solution simplifies the installation process, improves installation efficiency, and makes it easier for users to install the present invention on a vehicle by using an integrally molded mounting ring.

[0014] A further feature of this invention is that the mounting ring and the pump body are connected by an arc surface.

[0015] The above technical solution utilizes an arc-shaped connection between the mounting ring and the pump body to disperse stress and prevent stress concentration.
