A gas spring is a type of spring that, similar to a typical mechanical spring that relies on elastic deformation, uses compressed gas contained within an enclosed cylinder sealed by a sliding piston to pneumatically store potential energy and withstand external force applied parallel to the direction of the piston shaft.

Electric gas spring

The invention relates to a gas spring, in particular to an electric gas spring electrically driven. External force needs to be applied by hands to allow the prior gas spring to reciprocate or to be located, and the manual mode causes great inconveniences to users. The electric gas spring is characterized in that a drive motor, a decelerator and a coupling are mounted in a motor connecting sleeve of an electric drive device; a spiral reciprocating mechanism, a guide sleeve and a piston rod component are disposed in a gas spring cylinder barrel; the gas spring cylinder barrel is filled with nitrogen. The electric gas spring has the advantages that applying external force by hands is avoided, more convenient, safer and high-comfort humanized services are provided for users, and the application range of the gas spring is widened; the electric gas spring is compact in structure, simple to mount, convenient to use, stable in performance, safe and reliable, and widely applicable.

In at least one embodiment, a gas spring includes a casing having an inner surface defining in part a gas chamber, a piston rod and a seal. The piston rod is received at least partially in the casing for reciprocation along an axis between extended and retracted positions. The piston rod has an internal cavity defining a hollow space, a stop and a rod guide disposed adjacent to the inner surface of the casing to guide the reciprocation of the piston rod at least in part. The seal generally is provided between the piston rod and the casing to prevent gas leakage from the gas chamber.

The invention provides a method for confirming air spring parameter and a device thereof; the method includes steps of setting a target position of an air spring on the first zone through confirming a first zone, a second zone and a rotary axis between the first zone and the second zone; receiving quality parameter of the first zone input externally, and confirming the first distance between the gravity of the first zone and the rotary axis; according to the target position and the first distance, calculating parameter of the air spring. The scheme provided by the invention can effectively improve the accuracy of the air spring parameter.
