Description

Technical Field

[0001] The utility model relates to the technical field of fuel tank cover structures, in particular to a fuel tank cover structure. Background Art

[0002] With the shortage of oil resources, oil prices have risen sharply, and the illegal behavior of stealing automobile fuel has become increasingly rampant, especially for some heavy-duty logistics vehicles. Due to the limitations of the overall vehicle layout, the fuel tank is generally arranged on the outside of the vehicle frame for easy refueling and maintenance. However, this exposed installation layout provides an opportunity for stealing fuel. The common means of stealing fuel is to pry open the fuel tank cap, remove the fuel filler filter, and directly pass the oil suction hose into the fuel tank. The oil thief hides a high-power oil suction pump and a large container for storing stolen oil in the trunk of the car, and sucks the fuel into its container through the oil pump. At the theft scene, a full tank of fuel can be stolen in about three minutes using a high-power oil suction pump, which brings great economic losses to users.

[0003] At present, in order to prevent fuel theft, heavy-duty vehicle users generally adopt the following methods to modify the structure of the fuel tank. One method is to weld the fuel filler filter to the fuel tank so that the fuel thief cannot remove the filter and the oil pipe cannot be inserted into the fuel tank from here. However, this method is only applicable to iron tanks and iron filters, and plastic filters cannot be used, and it brings difficulties to the maintenance of the fuel tank; the other method is to add a padlock to the outside of the fuel tank cap to provide secondary protection for the fuel filler port, but this method also fails to effectively prevent the fuel filler port from being pried open, and thieves can also use special tools to open the padlock, which cannot play an effective preventive role and brings inconvenience to users when refueling. The third is an automobile fuel anti-theft method based on wireless communication for oil level detection. The system includes: an oil level monitoring sensor module, a buzzer alarm module, an on-board radio frequency receiving module, a CAN communication module, a GPS positioning module, and a GSM text message sending module, and is based on a complex system such as a gear cover for anti-theft. The system is extremely complex and expensive, and the gear cover is easier to open than the first and second anti-theft methods. The oil level detection method is a complex system that requires sending end hardware and receiving end hardware, requires multi-module operation, is expensive, and the gear cover is easily opened, resulting in anti-theft failure.
