Description

Technical Field

[0002] Currently, traditional fuel pumps generally suffer from complex structures. Existing technologies typically employ multi-component assembly, leading to inconvenient disassembly and high maintenance costs. Furthermore, the large number of components results in insufficient precision in their inter-component fit, increasing the risk of fuel leaks during long-term operation and impacting safety and environmental performance. While some improvements optimize the motor to alleviate these issues, they fail to fundamentally optimize the pump body structure and may even increase manufacturing costs or affect installation ease. Therefore, there is an urgent need for a structurally optimized fuel pump that simplifies the pump's structure through redesign, thereby making assembly more convenient. Utility Model Content

[0020] The technical solution of this utility model will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0021] In the description of this utility model, it should be noted that the terms "center," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," and "outer," etc., indicating the orientation or positional relationship, are based on the orientation or positional relationship shown in the accompanying drawings and are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model. Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0022] Reference Figures 1 to 7 The embodiments of this utility model will be further described below.

[0023] A more compact fuel pump 1 includes a fuel pump 1, a motor 2, and a control unit 3 connected to the motor 2. The control unit 3 forms a mounting cavity 31, within which a current overload protector 32, a switch 33, and a drive rod 34 are disposed. The current overload protector 32 is electrically connected to the switch 33. The switch 33 has a protruding control end. The drive rod 34 has a recessed drive groove 35, and the control end is located within the drive groove 35. One end of the drive rod 34 extends to the outside and slides within the mounting cavity 31. Furthermore, the axial movement of the drive rod 34 directly drives the switch 33 to open and close. The structure is compact and convenient. By simplifying the structure and improving compactness, the overall volume is significantly reduced, making the equipment more suitable for installation in confined spaces. Simultaneously, the internal wiring layout is optimized, effectively reducing the risk of wiring interference. This improvement significantly enhances installation and maintenance efficiency. The modular design makes wiring operations more convenient and troubleshooting faster. Furthermore, by reducing the number of connectors and optimizing the contact structure, the probability of poor contact is effectively reduced, enhancing operational reliability.

[0024] The control unit 3 is provided with a bracket 5. One end of the bracket 5 is provided with a connecting end, which is fixedly connected to the control unit 3. The bracket 5 has a hanging groove, one side of which is connected to the outside. The fuel nozzle is provided with a matching snap-fit ​​bend, which can move the snap-fit ​​bend of the fuel nozzle along the hanging groove into the interior. The bend of the snap-fit ​​bend allows the fuel nozzle to be hung on the bracket 5 for easy handling.

[0025] The control unit 3 has a connecting hole 41 that communicates with the outside. A limiting block 42 is installed inside the mounting cavity 31, positioned near the connecting hole 41. The limiting block 42 forms a limiting recess that can limit the wire harness entering through the connecting hole 41, ensuring the wire harness is neat and preventing it from becoming tangled and affecting the components in the mounting cavity 31. A limiting hole is also provided inside the mounting cavity 31 for easy positioning.

[0026] A sealing cover 51 extends from one side of the control unit 3 to the side of the sealing motor 2. The sealing cover 51 and the control unit 3 are separately configured and fixedly connected by bolts. The separate configuration of the sealing cover 51 and the control unit 3 is suitable for application scenarios that require frequent maintenance, customized modifications, or are budget-sensitive. In use, the sealing cover 51 and the control unit 3 can be integrally molded according to requirements. This is suitable for environments that require high mechanical strength and shock resistance. The integral molding greatly improves the overall mechanical strength and shock resistance, improves installation efficiency, and completely eliminates the risk of poor contact caused by loose bolts, thus extending the service life. Both embodiments can provide a more flexible technical solution for the fuel pump 1 product.

[0027] An oil drain section is provided on one side of the sealing cover 51. The output end of the motor 2 passes through the sealing cover 51 and extends into the oil drain section. One end of the oil drain section has an oil drain outlet 6 connected to the refueling gun. The oil draining structure is simple and convenient to construct.

[0028] This specific embodiment is merely an explanation of the present utility model and is not intended to limit the present utility model. After reading this specification, those skilled in the art can make modifications to this embodiment without contributing any inventive step, but as long as they are within the scope of the claims of the present utility model, they are protected by patent law.
