Description

Technical Field

[0001] This utility model relates to the field of fuel tank technology, specifically to a fuel tank fuel level detection device. Background Technology

[0002] Large vehicles are the foundation of logistics and transportation, fuel is the lifeblood of vehicles, and fuel tanks are containers used to store fuel.

[0003] A Chinese utility model patent (publication number: CN222617996U) discloses a fuel tank level detection device, comprising a protective shell, a fuel storage tube inside the protective shell, a connecting pipe at the bottom of the fuel storage tube, a transparent window on the fuel storage tube, a level window on the protective shell corresponding to the transparent window, and a cleaning assembly installed on the protective shell. The cleaning assembly includes a displacement block disposed inside the fuel storage tube, a scraping ring on the outside of the displacement block, and an extension rod connected to the top of the displacement block. The top end of the extension rod penetrates the fuel storage tube and is fixedly connected to a top plate of the protective shell. A drive motor is installed on the top of the top plate, and a lead screw is connected to the output end of the drive motor. When the fuel level in the tank reaches the bottom, the scraping ring can scrape the inner wall of the fuel storage tube as the displacement block moves down, preventing fuel from adhering for a long time and causing the transparent window to become blurred, thus facilitating the observation of the internal fuel level.

[0004] However, the following problems were found in the implementation of the relevant technologies:

[0005] The fuel tank itself is a relatively sturdy container (metal or engineering plastic), but during vehicle operation, it faces various dynamic loads and impacts. When the vehicle is driving, it will encounter various uneven road surfaces (potholes, speed bumps, gravel roads, etc.), which will generate continuous vibration and impact. Long-term severe vibration will cause fatigue cracking, loosening or even breakage of parts such as the fuel tank body, welds (metal fuel tank), fixed brackets, fuel pipe joints, and sensors.

[0006] Therefore, a fuel tank fuel level detection device is proposed. Utility Model Content
