Description
Technical Field
The utility model belongs to unmanned aerial vehicle release mechanism field, especially an unmanned aerial vehicle launches automatic release mechanism.
Background
Before the ejection rack is released, the unmanned aerial vehicle is usually placed on the frame of the sliding trolley, so that the unmanned aerial vehicle sometimes unexpectedly slides out of the frame before the ejection rack is released, and damages are caused.
Disclosure of Invention
In order to solve the problem, the utility model provides an unmanned aerial vehicle launches automatic release mechanism.
The automatic unlocking mechanism for the ejection of the unmanned aerial vehicle comprises an ejection frame, wherein an ejection trolley is placed on the ejection frame, and is characterized in that a bracket is fastened on the ejection trolley through bolts, a mounting plate is fastened on the right upper portion of the bracket in a threaded manner, a cam disc is hinged to the middle of the mounting plate, a heavy hammer is welded on the cam disc, a guide groove with gradually changed depth is formed in one surface of the cam disc, a mounting seat located behind the cam disc is arranged on a hinge shaft of the cam disc in a penetrating manner, the mounting seat is fixed on the mounting plate through bolts, a through hole is formed in the mounting seat, a spring pin is placed in the through hole, the unmanned aerial vehicle is placed on the bracket, an ejection block is fixed on a body of the unmanned aerial.
Furthermore, the front side surface and the rear side surface of the bracket are hollow, and the hollow part is provided with cross ribs welded on four corners of the hollow part.
Furthermore, the heavy hammer comprises a straight rod, a heavy block is inserted into one end of the straight rod, and the heavy block is locked through a bolt.
When the unmanned aerial vehicle catapult is used, the unmanned aerial vehicle is placed on a catapult trolley of a catapult rack which is already stressed before being prepared for catapult, and is connected to a gravity unlocking mechanism through a catapult block of an unmanned aerial vehicle body, and the gravity unlocking mechanism is in a locking state; after the ground inspection of the unmanned aerial vehicle is finished, starting an engine of the unmanned aerial vehicle and adding the engine to a maximum accelerator, wherein the gravity unlocking mechanism prevents the unmanned aerial vehicle from sliding out of a bracket under the thrust action of the engine, and then releasing an ejection trolley, and the ejection trolley and the unmanned aerial vehicle accelerate along a sliding rail of the ejection rack under the action of the elasticity of the ejection rack and the thrust action of the engine; at the moment of release, the heavy punch moves reversely relative to the ejection trolley under the action of inertia to drive the cam disc to rotate, so that the elastic pin is driven to retract to reach an unlocking position, the unmanned aerial vehicle is released, and at the later stage of ejection acceleration, when the speed of the unmanned aerial vehicle exceeds the speed of the ejection trolley, the unmanned aerial vehicle slides out of the ejection trolley to fly.
The beneficial effects of the utility model are that realize unmanned aerial vehicle and launch automatic unblock, prevent that unmanned aerial vehicle from unexpected ground roll-off frame before launching the dolly release, cause the damage.
