Description

Technical Field

[0001] The present invention relates to the technical field of unmanned aerial vehicles, and in particular to an unmanned aerial vehicle fixing device used for an unmanned aerial vehicle nest. Background Art

[0002] Most of the drones currently used in machine nests for inspection and reconnaissance are traditional quad-rotor drones that use the same flight principle as helicopters. Such drones can stop and go at will and are suitable for inspection and reconnaissance tasks. However, they are limited by their short range and flight time, resulting in low working efficiency and range of the drones.

[0003] A Chinese patent document with authorization announcement number CN 220865682 U discloses a multi-rotor UAV, which solves the above-mentioned problems. However, when the multi-rotor UAV is in use, two spring caps need to be pressed simultaneously when the battery is removed, so that the two limit blocks are separated from the corresponding limit grooves. However, when the spring caps are pressed, the multi-rotor UAV is usually not docked stably, which makes it impossible to remove it smoothly, thereby making it impossible to charge or replace the battery of the multi-rotor UAV. Summary of the invention

[0006] The beneficial effect is that when the drone fixing device for the drone nest of the present invention is used, the transmission plate is first driven to rotate by the rotating driving member, the transmission plate rotates to drive the transmission rod, the rotation of the rotating rod drives the connecting plate to rotate, and then drives the pressing block to rotate, so that the pressing block presses the end of the battery terminal of the drone into the limit space, and the battery in the drone can be taken out at this time. When the drone fixing device for the drone nest of the present invention is used, the drone is pressed into the limit space between the holding limit plate and the track by the pressing block, thereby fixing the drone and facilitating the grabbing mechanism to grab the battery.

The axis of the rotating hole coincides with the axis of the cylinder where the arc surface 9 is located, and a rotating rod 10 is rotatably installed in the rotating hole. An avoidance groove 14 is provided on the opposite side of the two holding and limiting plates 2 for avoiding the holding claws that clamp the drone battery. A limiting groove 11 is also provided on the upper end surface of the holding and limiting plate 2, and the limiting groove 11 is adapted to the casing of the battery end of the drone for limiting the drone. Each holding and limiting plate 2 is also provided with three weight-reducing holes 15 arranged at intervals along the left and right directions to reduce the weight of the holding and limiting plate 2 and save materials at the same time.

[0032] A rotating seat 19 is provided at the right end of the limiting groove 11, and a rotating groove 20 is opened on the rotating seat 19. Through holes are opened on the left and right side walls of the rotating groove 20. A rotating rod is coaxially fixed in the two through holes of each rotating groove 20. A bearing is coaxially connected to the rotating rod. The rotating rod is coaxially fixed to the inner ring of the bearing, and a guide wheel 21 is coaxially fixed on the outer ring of the bearing. The spacing between the two guide wheels 21 and the distance between the two limiting plates are adapted to the battery end of the drone.

[0033] The horizontal linear module mechanism is disposed on the track 1 and extends in the left-right direction.

[0035] The gripping assembly includes two holding claws and a rotating motor for driving the holding claws to rotate. The output shaft of the rotating motor is transmission-connected to the right end of the holding claw, thereby driving the right end of the holding claw to rotate to change the distance and space between the left ends of the two holding claws, thereby enabling the gripping assembly to grip the battery.

[0036] A top block is provided on one side surface opposite to the two holding clamps, and the top block is correspondingly arranged and adapted to the spring cap of the drone. When in use, the two top blocks of the two holding clamps are used to press the two spring caps on the drone, so that the limit block of the battery of the drone is disengaged from the limit groove 11, and the battery is taken out; and after the battery is taken out and replaced, the battery can be directly pushed into the drone through the horizontal linear module mechanism to complete the battery replacement operation.

[0037] The pressing assembly includes a pressing block 3 , a connecting plate 4 , a transmission rod 5 , a transmission plate 6 and a pressing motor 7 .

[0038] The connecting plate 4 includes a connecting portion and two crank arms 16 symmetrically distributed on both sides of the connecting portion along the front-to-back direction. Each crank arm 16 has a notch at one end away from the connecting portion that matches the arc surface 9 on the corresponding side, and the inner wall of the notch is tightly attached to the arc surface 9. The two notches are connected to the rotating rod 10 on the corresponding side.

[0039] The pressing block 3 includes a connecting section 17 and a pressing section 18. The connecting section 17 is connected to the connecting portion. The pressing section 18 is used to press the casing of the battery end of the drone. A hinge groove 13 is also provided at the connecting position of the connecting section 17 and the pressing section 18.

[0040] A cushion 12 is provided on the lower end surface of the pressing section 18 of the pressing block 3. The upper end surface of the cushion 12 is in close contact with the lower end surface of the pressing section 18. The lower end surface of the cushion 12 is an inclined surface arranged upward from right to left.

[0041] The left end of the transmission rod 5 is rotatably assembled in the hinge groove 13. The left end of the transmission plate 6 is hinged to the right end of the transmission rod 5, and the transmission plate 6 is a plate with a cam-shaped structure.

[0042] A reversing reducer 8 is connected to the output shaft of the pressing motor 7 . The output shaft of the reversing reducer 8 extends in the front-rear direction and is connected to the right end of the transmission plate 6 .

[0043] When the drone fixing device for a drone nest of the present invention is used, the pressing block 3 is first moved up and down so that the pressing block 3 presses the end of the drone into between the two holding limit plates 2, and the drone is fixed on the track 1 between the two holding limit plates 2. At this time, the battery in the drone is taken out by the grabbing component, and a new battery is replaced by moving the track 1 up and down. Then, the drone is pressed between the two holding limit plates 2 by the pressing block 3, and the battery is pushed into the drone by the grabbing mechanism.

[0044] When in use, the drone fixing device for a drone nest of the present invention presses the drone into the cavity between the holding limit plate 2 and the track 1 through the pressing block 3, thereby fixing the drone and facilitating the grabbing mechanism to grab the battery.
