[0001] This utility model relates to a drone launcher, specifically a drone launcher with an automatically tilting rocker arm, belonging to the field of drone launch technology. Background Technology

[0002] A drone is an unmanned aerial vehicle that is widely used in the military field, while a drone launcher is a device specifically designed to launch drones.

[0003] Currently, most low-speed drones use tail-thrust engines. However, during the launch process, the tail propeller of the tail-thrust engine is prone to colliding with the drone launcher. Furthermore, after the launcher support rod collapses, it is easy for it to rebound and collide with the tail propeller again. This poses a serious threat to the safety of the drone and affects its normal launch. Summary of the Invention

For those of ordinary skill in the art, the specific meaning of the above terms in the application can be understood according to the specific circumstances.

[0036] Some embodiments of the application will be described in detail below with reference to the accompanying drawings. In the case of no conflict, the following embodiments and features in the embodiments can be combined with each other.

[0037] As Figures 1 to 7As shown, the unmanned aerial vehicle launching rack with automatic rocking arm flattening provided by the embodiment comprises a front support frame 1-1, a front rocking arm 1-3, an upper bracket 1-6, a rear rocking arm 1-8 and a rear support frame 1-10. The front support frame 1-1 and the rear support frame 1-10 are connected with the upper bracket 1-6 by screws respectively, supporting the upper bracket 1-6. The front support frame 1-1 is fixed by being connected with the middle part of the upper bracket 1-6 through two connecting shafts 1-5.

[0038] The shaft sleeve 1-6-5 is welded at the through hole of the upper bracket connecting frame 1-6-1. The rotating shaft 1-7 is inserted into the upper bracket 1-6 through the shaft sleeve 1-6-5, and the front rocking arm 1-3 and the rear rocking arm 1-8 are connected with the rotating shaft 1-7 respectively, so that the front rocking arm 1-3 and the rear rocking arm 1-8 can rotate around the rotating shaft 1-7. A pair of torsion springs 1-2 are installed on the rotating shaft 1-7 at intervals, one end of each torsion spring 1-2 is connected with the front rocking arm 1-3 and the rear rocking arm 1-8 respectively, and the other end is connected with the rear flattening support beam 1-6-6. The bottom of the front rocking arm 1-3 and the rear rocking arm 1-8 is respectively provided with two limiting blocks 1-13. The bottom of the front rocking arm 1-3 is provided with a pull rod 1-14, and the pull rod 1-14 is located between the two limiting blocks 1-13 on the front rocking arm 1-3.

[0039] The rocket support frame 1-9 is connected with the rear rocking arm 1-8 by screws. The hook devices 1-11 are respectively installed in the grooves on the outer sides of the front rocking arm 1-3 and the rear rocking arm 1-8, and the hook devices 1-11 can clamp the side supporting points of the unmanned aerial vehicle 3 installed on the frame plate, so as to temporarily fix the unmanned aerial vehicle before launching.

[0040] One end of the constant force rod 1-4 is connected with the front support frame 1-1, and the other end is connected with the bottom pull rod 1-14 of the front rocking arm 1-3 through a shear pin 1-5. The shear force of the shear pin 1-5 is smaller than the thrust of the boost rocket 2, so as to ensure that the thrust of the boost rocket 2 is sufficient to quickly push off the shear pin 1-5.

[0041] The buffer locking mounting block 1-6-2 and the rear flattening support beam 1-6-6 are welded on the upper bracket connecting frame 1-6-1, and the two rear flattening support beams 1-6-6 are fixed on the upper bracket 1-6 and located behind the front rocking arm 1-3 and the rear rocking arm 1-8. The buffer locking mounting block 1-6-2 is located behind the rear flattening support beam 1-6-6, and the buffer locking mounting block 1-6-2 has an inverted "L" shape structure. The buffer plate spring 1-6-4 is fixedly installed on the buffer locking mounting block 1-6-2, and the middle part of the buffer plate spring 1-6-4 is protruded, and the top of the buffer locking mounting block 1-6-2 forms a cavity which can accommodate the limiting block 1-13. The buffer rubber pad 1-6-3 is bonded to the inner side of the buffer locking mounting block 1-6-2 and located above the buffer plate spring 1-6-4, and is used for buffering the limiting block 1-13 and reducing the impact sound generated during flattening.

[0042] When the unmanned aerial vehicle is assembled before launching, the unmanned aerial vehicle launching stand 1 is clamped to the side support point of the unmanned aerial vehicle 3 installed on the frame plate through the clamping device 1-11, and the rocket support stand 1-9 is tightened against the boost rocket 2 by screwing in, as shown. Figure 5

[0043] Before launching, the constant force rod 1-4 pulls the front rocker arm 1-3 to limit its movement, so as to realize the locking of the clamping device 1-11, and at the same time, the two rear inverted support beams 1-6-6 limit the tendency of the front rocker arm 1-3 and the rear rocker arm 1-8 to be inverted backward, so that the whole launching stand realizes the fixation of the unmanned aerial vehicle 3 before launching. At the same time, the rocket support stand 1-9 realizes the tightening against the boost rocket 2.

[0044] In the embodiment, the clamping device 1-11 is a prior art, and reference can be made to the patent document with the application number CN201420144257.X and the invention name of a releasing mechanism of an unmanned aerial vehicle launching stand. As a person skilled in the art should know, other similar clamping device 1-11 structures can also be adopted under the premise of realizing the locking / release function.

[0045] Since the thrust of the boost rocket is sufficient to ensure that the shear pin 1-5 is pulled off, when the boost rocket 2 is ignited, the shear pin 1-5 is quickly pushed off under the action of the boost rocket 2, the front rocker arm 1-3 and the rear rocker arm 1-8 are accelerated to be inverted forward under the action of the torsional spring 1-2, and at the same time, the clamping device 1-11 is released, and the unmanned aerial vehicle 3 starts to move forward; when the front rocker arm 1-3 and the rear rocker arm 1-8 are inverted to be horizontal to the upper bracket 1-6, the limiting block 1-13 at the bottom contacts the buffer plate spring 1-6-4, is clamped into the cavity between the buffer plate spring 1-6-4 and the buffer locking mounting block 1-6-2 and cannot rebound, and contacts the buffer rubber pad 1-6-3 above to realize buffering, thereby preventing the rocker arm from rebounding and colliding with the propeller of the unmanned aerial vehicle.

[0046] The technical scheme of the unmanned aerial vehicle launching stand with the rocker arm automatically inverted is provided, and there are many methods and ways to realize the technical scheme, and the preferred embodiment of the utility model is described above, and it should be pointed out that for ordinary technical personnel in the technical field, some improvements and decorations can be made without departing from the principle of the utility model, and these improvements and decorations should also be regarded as the protection range of the utility model. The unexplained components in the embodiment can be realized by using the prior art.​
