When a machine body falls due to lack of power, since the protective shell is arranged on the surface of the machine arm and the drive motor, and the protective shell is arranged in layers like a spider web, the force impacting the machine arm and the drive motor is unloaded through the impact of the layers of the protective shell, thereby protecting the machine arm and the drive motor. When the machine body turns over and falls, the acceleration sensor detects abnormal speed and transmits a signal to a controller in the machine body, so that the buffer cover is controlled to pop up through the cylinder, so that the buffer cover and the machine body are suspended in the air to form a buffer zone, which can effectively reduce the impact force on the components in the machine body, thereby protecting the electronic components in the machine body.

Based on the embodiments in the implementation mode, other embodiments obtained by those skilled in the art without creative work are all within the protection scope of the present invention.

[0026] The specific embodiments of the present utility model are described below in conjunction with the accompanying drawings. Specific embodiment one:

[0029] Furthermore, a groove 8 is provided on the top surface of the body 1, and a cylinder 9 is provided inside the groove 8. The cylinder 9 is axially symmetrically arranged inside the groove 8, and a buffer cover 10 is provided at the end of the cylinder 9, and the shape of the buffer cover 10 corresponds to the groove 8. Therefore, through the setting of the cylinder 9, the buffer cover 10 can be controlled to pop up, so that a buffer zone is formed between the buffer cover 10 and the body 1 to reduce the impact force on the body 1.

[0030] Furthermore, a connecting arm 12 is provided inside the groove 8, and the end of the connecting arm 12 is connected to the bottom surface of the buffer cover 10. The buffer cover 10 and the groove 8 are connected by the setting of the connecting arm 12. An acceleration sensor 11 is provided inside the groove 8. Through the setting of the acceleration sensor 11, abnormal acceleration of the body 1 is detected, and the signal is transmitted to the control structure in the body 1, thereby controlling the cylinder 9 to open.

[0032] During flight, the propeller 13 can be driven to rotate by the driving motor 7, so that the body 1 takes off. During the flight, the surrounding environment can be observed through the camera 2. When the body 1 falls, since the protective shell 6 is arranged on the surface of the arm 3 and the driving motor 7, the impact can be buffered by the protective shell 6, thereby protecting the arm 3 and the driving motor 7. At the same time, when the acceleration sensor 11 detects an abnormal speed, the signal can be transmitted to the controller in the body 1, so that the buffer cover 10 is controlled to pop up through the cylinder 9, so that the buffer cover 10 and the body 1 are suspended in the air to form a buffer zone, which can effectively reduce the impact force on the components in the body 1, thereby protecting the electronic components in the body 1. Specific embodiment 2:

[0034] Reference Figure 7 The only difference between this embodiment and the first embodiment is that the interior of the arm 3 is hollowed out and a cross support rod is provided inside to increase the stability of the arm 3 and realize the lightweight design of the drone body.
