The invention relates to an unmanned aerial vehicle footpad folding and unfolding device and an unmanned aerial vehicle. The unmanned aerial vehicle footpad folding and unfolding device comprises a support, a motor fixed to the support, a synchronous driving part connected to an output shaft of the motor, a plurality of footpads rotatably connected to the support, worm wheels fixed to the corresponding footpads and worms rotatably connected to the support and engaged with the worm wheels. The motor drives the worms to rotate through the synchronous driving part. The multiple footpads of the unmanned aerial vehicle footpad folding and unfolding device are controlled to be folded and unfolded through the motor, so that the unmanned aerial vehicle footpad folding and unfolding device is smallin size, simple to control and low in cost. In addition, the footpads can be locked deadly by utilizing reverse self-locking characteristics of driving of the worms and the worm wheels, a dead locking mechanism does not need to be arranged additionally, the volume of the whole unmanned aerial vehicle footpad folding and unfolding device can be reduced, weight reduction of the unmanned aerial vehicle is facilitated, and accordingly the endurance mileage of the unmanned aerial vehicle is increased.
Description
technical field [0001] The invention belongs to the technical field of aircraft, and in particular relates to an unmanned aerial vehicle tripod retractable device and an unmanned aerial vehicle. Background technique [0002] Each tripod of the existing UAV is controlled by a motor. When it is applied to a UAV with multiple tripods, the size of the tripod retractable device is too large, the control unit is complicated and the cost is high; and a lock is required. When the tripod is dead, a locking mechanism is added independently to make the whole structure larger. Contents of the invention [0003] The technical problem to be solved by the present invention is aimed at the existing unmanned aerial vehicle with multiple tripods, each tripod is retracted and retracted by a motor control, the tripod retractable device is too large in size, the control unit is complicated and the defect is high in cost , Provide a UAV tripod retractable device. [0004] The technical soluti...
