How the trunk strut works :
The tail-box strut is mainly composed of air cylinder, piston rod, guide rod and sealing ring. Its working principle is to use the volume change of compressed gas and the principle of fluid mechanics. When the tail door is closed, the pressure cylinder is filled with high pressure gas, and the piston is in a retracted state. When the tailgate is opened, the piston rod is stretched, and the compressed gas will enter the reduced volume through the sealing circulation, forming liquid pressure, which supports the tailgate to open
Trunk strut material :
Car trunk struts are usually made of materials such as stainless steel or aluminum alloy. These materials have good corrosion resistance and strength, and can withstand the weight of the tailgate and frequent opening and closing operations. Stainless steel struts perform well in harsh environments, while aluminum alloy has a lighter weight and good toughness
