The invention also provides a method for using the UAV, including the steps of UAV control, landing site selection, the first shock absorption and the second shock absorption, etc. The method of the present invention has a high degree of automation, and the operator only needs manual Controlling the landing site of the drone has low operational difficulty, and the method of the invention is highly operable.

The invention discloses a shock absorbing device, which comprises a belt pulley, a vehicle frame, a V-belt, a bearing seat, a lower shock absorbing pad, an isolation plate, an upper shock absorbing pad, a pressing plate and a pressing plate adjusting bracket. In the present invention, an isolation plate is installed between the bearing seat and the lower shock-absorbing pad, and upper shock-absorbing pads and pressure plates are installed on both sides of the isolation plate. Compression and deformation, at the same time, the upper shock pad generates an upward thrust, which is pushed back by the pressure plate, and then transmitted to the lower shock pad by the isolation plate, so that the lower shock pad receives an upward pull and a downward thrust at the same time, and most of them are affected. The force is offset, so that the tensile deformation of the rubber block of the lower shock-absorbing pad is reduced, thereby improving the life of the shock-absorbing pad, reliable shock absorption, and improving the working stability of the operating device.

A shield plate is provided with a plate-like member and a stress-concentrating section which is formed over the entire surface of the plate-like member and bends when an external force is applied.
