Description

Technical Field

[0001] This utility model relates to the field of unmanned aerial vehicle (UAV) technology, and in particular to a modular combined deceleration parachute. Background Technology

[0002] A drag chute, also known as a deceleration chute, is a parachute-shaped device used to reduce the landing speed of an aircraft. It typically consists of a main parachute, a pilot chute, and a canopy, and is housed in a canopy compartment at the tail of the aircraft. During the landing roll, the pilot opens the canopy compartment door, the pilot chute opens first, pulling out the canopy, and then the main parachute opens. Once the canopy is pulled out and unfolds, it increases air resistance, dragging the aircraft backward to slow it down and shorten the landing distance.

[0003] Currently, when a drone lands, a drag chute can provide some cushioning. However, if the drag chute is not yet separated from the drone when it is about to hit the ground, it may rub against the ground as the drone glides, causing damage to the drag chute. To address this, we provide a modular combination drag chute. Utility Model Content

Detailed Implementation

[0025] This application provides a modular combined deceleration parachute. Through the arrangement of connecting components—shell one, shell two, rectangular block, inclined block, electromagnetic block, magnetic plate, positioning rod, restoring spring, and ball bearings—when the drone is about to land, the electromagnetic block is energized, generating magnetic poles identical to those of the magnetic plate. At this point, the electromagnetic block attracts the magnetic plate, and the inclined block and rectangular block move closer to the electromagnetic block. The restoring spring, no longer restricted by the inclined block, begins to recover. Simultaneously, the positioning rod disengages from the interior of shell one, and shell two, no longer restricted, separates from shell one, thus achieving separation of the deceleration parachute body from the drone. Furthermore, by providing a mounting part, through the cooperation of a mounting plate, internal threaded block, bolt, and sleeve block, the mounting plate is connected to the drone via bolts, and the bolts are connected to the two internal threaded blocks, with the sleeve block positioned in the middle of the bolt, thus achieving connection between the mounting part and the drone.

[0026] Example 1

[0027] The technical solution in this application embodiment is to effectively solve the technical problem that when a drone lands, the drag chute can provide a certain buffering effect, but if the drag chute has not yet separated from the drone when it is about to reach the ground, the drag chute may rub against the ground while the drone is gliding, causing some damage to the drag chute. The overall idea is as follows:

[0028] like Figures 1 to 4To address the problems existing in the prior art, this utility model provides a modular combined deceleration parachute, including a deceleration parachute body 1. An installation mechanism 2 is provided on one side of the deceleration parachute body 1. The installation mechanism 2 includes an installation part 21 and a connecting component 22. The connecting component 22 is disposed between the installation part 21 and the deceleration parachute body 1. The installation part 21 is used to connect with a drone, and the connecting component 22 is used to connect with the deceleration parachute body 1. The installation part 21 includes an installation plate 211, an internal threaded block 212, a bolt 213, and a sleeve block 214. The installation plate 211 is connected to the drone by bolts. Two internal threaded blocks 212 are fixedly connected to one side of the installation plate 211. The surface of the internal threaded block 212 is provided with threaded holes. The internal threads of the internal threaded block 212 are connected to the bolt 213, and the sleeve block 214 is movably sleeved on the outside of the bolt 213.

[0029] By adopting the above technical solution, the mounting plate 211 is connected to the UAV by bolts, the bolt 213 is connected to two internal threaded blocks 212, and the sleeve block 214 is located in the middle of the bolt 213.

[0030] Specifically, the connecting assembly 22 includes a first housing 221, a second housing 222, a rectangular block 223, a beveled block 224, an electromagnetic block 225, a magnetic plate 226, a positioning rod 227, a restoring spring 228, and a ball bearing 229. The first housing 221 is fixedly connected to one side of the sleeve block 214. The second housing 222 is inserted inside the first housing 221. A rectangular block 223 is inserted into one side of the inside of the second housing 222. One end of the rectangular block 223 is connected to the deceleration chute body 1. A ramp block 224 is fixedly connected to one side of 23, a magnetic plate 226 is fixedly connected to one side of the ramp block 224, an electromagnetic block 225 is fixedly connected to one side of the interior of housing 221, a positioning rod 227 is provided on both sides of the ramp block 224, a ball bearing 229 is fixedly connected to the side of the positioning rod 227 near the ramp block 224, a restoring spring 228 is fixedly connected between the ball bearing 229 and housing 222, and the restoring spring 228 is arranged around the outside of the positioning rod 227.

[0031] By adopting the above technical solution, when the drone is about to land, the electromagnetic block 225 is energized, and the electromagnetic block 225 generates magnetic poles with the same magnetism as the magnetic plate 226. At this time, the electromagnetic block 225 and the magnetic plate 226 are attracted to each other, and the inclined block 224 and the rectangular block 223 move closer to the electromagnetic block 225. The restoring spring 228 is no longer restricted by the inclined block 224 and begins to restore itself. At the same time as restoring itself, it drives the positioning rod 227 to detach from the interior of the first shell 221. The second shell 222 is no longer restricted and separates from the first shell 221, thereby realizing the separation of the deceleration parachute body 1 from the drone. When installing the deceleration parachute body 1, the electromagnetic block 225 is de-energized first. At this time, the electromagnetic block 225...

[0032] Working principle: In use, the mounting plate 211 is connected to the drone via bolts, and bolt 213 is connected to two internally threaded blocks 212, with the sleeve block 214 located in the middle of bolt 213. When the drone is about to land, the electromagnetic block 225 is energized, generating magnetic poles with the same magnetism as the magnetic plate 226. At this time, the electromagnetic block 225 and the magnetic plate 226 are attracted to each other, and the inclined block 224 and the rectangular block 223 move closer to the electromagnetic block 225. The restoring spring 228 is no longer restricted by the inclined block 224 and begins to return to its original position. During the return, the positioning rod 227 is disengaged from the interior of the first housing 221, and the second housing 222 is no longer restricted and... Separating from the shell 221, thus separating the parachute body 1 from the drone. When installing the parachute body 1, first de-energize the electromagnet 225. At this time, the electromagnet 225 no longer generates magnetic poles. Then insert the shell 222 into the interior of the shell 221. After insertion, pass an opposite current through the electromagnet 225. The opposite current refers to the current passed through the electromagnet when the parachute body 1 is separated from the drone. At this time, the electromagnet 225 and the magnetic plate 226 generate the same magnetic poles. Under the repulsive force of the magnetic poles, the inclined block 224 pushes the ball 229 and the positioning rod 227 and compresses the restoring spring 228, thus realizing the installation of the parachute body 1 from the drone.

[0033] Finally, it should be noted that the above embodiments are merely examples for clearly illustrating the present invention and are not intended to limit the implementation. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the protection scope of this invention.
