The working principle is based on the hydraulic mechanics principle. When the trunk lid is closed, the hydraulic oil is compressed in the hydraulic cylinder; When the trunk cover needs to be opened, the trunk cover is lifted manually or electrically, and the hydraulic oil is squeezed to produce upward pressure, which is transmitted to the piston through the piston rod, thus supporting the trunk cover. When the trunk cover reaches the desired position, the pressure of the hydraulic oil and the support force on the piston are balanced, and the trunk cover can be stably held in this position
Advantages
The support force is stable and reliable : no matter what position the trunk cover is opened to, the hydraulic support rod can provide enough support force, so that the trunk cover can be statically maintained in this position, without accidentally closing or falling
easy to use : open the trunk cover just gently lift, the hydraulic support rod will automatically support the trunk cover; When closed, the hydraulic support rod retracts and does not hinder the closing of the trunk lid
improved convenience : The use of hydraulic support rods makes it easier for people to store and remove items, without the need to use hands or other objects to support the trunk lid
