The latest research progress of anti-leakage technology of fuel tank lock
With the development of science and technology and the enhancement of environmental awareness, the automobile industry is facing unprecedented challenges and opportunities. As one of the important parts of automobile, the safety, reliability and anti-leakage performance of fuel tank lock have attracted much attention. This paper will summarize the latest research progress of anti-leakage technology of fuel tank lock from three aspects: application of new materials, structural design optimization and intelligent management.
1. Application of new materials
In recent years, with the progress of nanotechnology and composite materials science, a variety of high-performance new materials have been successfully applied in the field of fuel tank locks. Among them, carbon fiber reinforced plastics (CFRP) and its modified alloy materials are the most representative high-strength lightweight materials. This kind of material has the characteristics of strong corrosion resistance, light weight, high strength, etc., which can improve the overall performance of the fuel tank lock and effectively reduce the quality of the whole vehicle, thus achieving the purpose of energy saving and emission reduction. In addition, some elastomers with good sealing and high temperature resistance, such as silicone rubber, are also widely used in the sealing ring between the tank cover plate and the car body to further enhance its anti-leakage ability.
2. Structural design optimization
In view of the problems existing in traditional mechanical locks, such as easy damage and inconvenient operation, modern oil tank locks generally adopt more advanced electronic control systems to control the opening/closing actions. Specifically, it mainly includes the combination scheme of electromagnetic induction mechanism and microswitch and the direct drive of electric motor. The former triggers the internal sensor signal to feed back to the ECU through the magnet arranged on the refueling gun, and then judges whether to allow unlocking; The latter is to monitor the current position information and adjust the force in time when the motor drives the gear set to open and close, so as to prevent leakage caused by too tight or loose.
3. Intelligent management
Considering all kinds of abnormal situations that may occur in daily use (such as forgetting to close the door handle or deformation caused by external impact), many new models are equipped with smart key systems based on radio frequency identification (RFID) technology. It can automatically detect the current state of the vehicle and send a warning prompt to the driver so as to take corresponding measures to avoid potential risks. In addition, with the support of the Internet of Things platform, car owners can also use the smartphone APP to remotely monitor the health of their cars and even execute certain specific instructions such as emergency power off.
Summary:
In short, with the continuous emergence of new technologies in related fields, the future fuel tank lock should not only continue to strengthen the basic physical protection level, but also actively embrace the digital transformation trend and develop in a more humane, convenient and efficient direction. I hope the above contents are helpful to you!
