Unmanned aerial vehicle with a buffering protection device through using a knee structure as basis to achieve pressure bending

Abstract

The invention discloses an unmanned aerial vehicle with a buffering protection device through using a knee structure as a basis to achieve pressure bending. The unmanned aerial vehicle structurally comprises a supporting frame, an operating cabin, blades, an intelligent buffering device, an empennage, and wings. An internal stressed frame makes contact with a floor, power is received through a joint block at the same time, bending is carried out, an overall structure at the upper portion is pressed downwards at the same time, then a universal wheel at the upper portion is rotated, then a sliding frame is displaced and rotated, and a supporting pad is subjected to suction and separation, so that the device is prevented from quickly making contact with the damaged impression of a support; and then an internal pressing pad is pushed through a hinge rod at the upper part, so that internal gas is discharged, an internal air pressure pad is expanded at the same time, and then a memory spongeinside a damping pad is compressed, so that impulsive force is subjected to secondary pushing for damping, and the gas displacement replaces an internal spring to buffer the operation of the internaldevice.

Description

technical field [0001] The invention relates to the field of unmanned aerial vehicles, in particular to an unmanned aerial vehicle with a buffer protection device that is bent under compression based on a knee structure. Background technique [0002] When the current UAV is landing, the spring inside the internal rigid bracket is used to shock-absorb and buffer the device through the spring’s rebound and contraction after the device touches the ground when it lands, but in this way: [0003] When performing landing buffering work, when the spring is used for shock absorption and buffering, a critical point of compression will occur when the spring is compressed, and at the same time, the effect of shock absorption will be reduced under the condition of continued compression, and it cannot be buffered. At the same time, through the internal The rigid bracket is used to connect the equipment and the spring. After contacting the bottom surface, it is easy to cause the internal ...

Problems solved by technology

[0003] When performing landing buffering work, when the spring is used for shock absorption and buffering, a critical point of compression will occur when the spring is compressed, and at the same time, the effect of shock absorption will be reduced under the condition of continued compression, and it cannot be buffered. At the same time, through the internal The rigid bracket connects the equipment and the spring. After contacting the bottom surface, it is easy to cause the internal bracket to break due to force, so that the components of the drone are damaged and need to be replaced frequently, or even scrapped.
