AI Technical Summary
Technical Problem
Existing cylinders achieve buffering or acceleration effects through inner and outer piston rod designs, resulting in complex structures and large radial dimensions.
Method used
A pneumatic buffer cylinder is designed, comprising a main cylinder and a buffer cylinder. The buffer cylinder consists of an inner cylinder, an outer cylinder, an inner piston, and an outer piston. The buffering effect is achieved by utilizing the interaction between the liquid chamber and the air chamber of the inner cylinder, without the need for external hydraulic system adjustment.
Benefits of technology
The cylinder structure was simplified, enabling effective buffering and starting in drone acceleration testing, and the radial dimensions were reduced.

Abstract
This utility model discloses a pneumatic buffer cylinder, including a main cylinder and a buffer cylinder located at the rear end of the main cylinder. The buffer cylinder includes an inner cylinder, an outer cylinder, an inner piston, and an outer piston. The outer cylinder is connected to the main cylinder. The inner cylinder reciprocates within the main cylinder and the outer cylinder. The inner piston is located inside the inner cylinder, and the outer piston is located inside the outer cylinder and connected to the rear end of the inner cylinder. The inner piston divides the inner cylinder into an air chamber and a liquid chamber. The air chamber is located at the front end of the inner piston, and the liquid chamber is connected to the chambers on both sides of the outer piston within the outer cylinder. This utility model sets a buffer cylinder at the rear end of the main cylinder. The hydraulic oil in the two chambers of the outer cylinder is self-adjusted through the liquid chamber of the inner cylinder, thereby realizing the axial movement of the inner cylinder. During initial startup, the high pressure of the air chamber can instantly start the buffer cylinder. During the recovery of the drone, the buffer cylinder can play a good buffering role without the need for external hydraulic system adjustment, and the structure is simpler.
