Description

Technical Field

[0001] The utility model relates to the technical field of unmanned aerial vehicles, and in particular to a protective device for unmanned aerial vehicles. Background Art

[0002] Unmanned aircraft, also known as drones, are unmanned aircraft that are mainly controlled by radio remote control or its own program. Drones are gradually replacing early warning aircraft and manned aircraft due to their small size, strong safety, flexible and convenient use, and high resolution of low-altitude flight. Drone technology has developed rapidly. During the flight of a drone, any malfunction of any component or link may cause the aircraft to lose control and crash, resulting in damage to the aircraft itself and onboard equipment, and further causing huge property losses.

[0003] At present, the existing drone protection devices generally adopt a buffer structure at the bottom bracket to reduce the degree of damage when falling. For example, the Chinese patent with the publication number CN217022874U discloses a drone falling safety protection device, including two brackets, the two brackets are respectively fixed on both sides below the drone body, and the two brackets are provided with a lower plate directly below the two brackets. The lower parts of the two brackets are connected with a buffer mechanism between the lower plate and the lower plate. A bottom plate is provided below the lower plate, and a slide groove is provided below the lower plate. A slide plate is fixed above the bottom plate, and the slide plate is slidably arranged in the slide groove. When the drone falls and the bracket falls to the ground, the bottom plate of the protection device will fall to the ground first. By unfolding the bottom plate, the contact area between the bottom of the bracket and the ground can be increased to prevent it from falling. The buffer mechanism under the bracket can buffer the force received by the bracket when it falls, thereby preventing it from being damaged when falling.

[0004] Although this type of existing technology can provide cushioning protection for a falling drone to a certain extent, the effect of the cushioning protection is limited. It is difficult to protect a drone that falls from a high altitude, and serious drone crashes are still likely to occur.

[0005] Therefore, the present application provides a drone protection device to solve the above technical problems. Utility Model Content

[0006] The technical problem to be solved by the utility model is to provide a drone protection device to solve the problem that the existing drones are difficult to provide a high-altitude fall protection effect only by relying on the buffering of the bottom bracket.

[0007] In order to solve the above technical problems, the utility model provides the following technical solutions:

[0008] A drone protection device comprises a drone body, wherein a vertical mounting tube penetrates the middle part of the drone body, a storage tube is detachably mounted in the mounting tube, the lower end of the storage tube extends out of the lower port of the mounting tube and is located below the lower end surface of the drone body, a buffer frame is elastically mounted on the lower end of the storage tube, feet are fixed at both ends of the buffer frame, a wind collecting plate connected to the storage tube is fixed in the middle part of the lower end surface of the buffer frame, the lower end surface of the wind collecting plate is provided with an air inlet opening, and a parachute is connected in the storage tube, the parachute comprises an umbrella tube vertically stored in the storage tube, a sealing plate for blocking the inside of the storage tube is fixed to the lower end of the umbrella tube, an umbrella cover is mounted on the top end of the umbrella tube, and the umbrella cover is folded and tightly attached to the surface of the umbrella tube.

[0009] Optionally, a horizontal electric telescopic rod is fixed to the middle of the upper end surface of the drone body, and a baffle is fixed to the shaft of the electric telescopic rod. The baffle extends to the port on the mounting tube and limits and blocks the top of the storage tube and the parachute.

[0010] Optionally, wings are symmetrically fixed around the drone body, and rotor blades are provided on the wings.

[0011] Optionally, the outer edge surface of the receiving tube is configured with a thread adapted to the inner wall of the mounting tube.

[0012] Optionally, a movable cylinder is fixed to the middle of the upper end surface of the buffer frame, the movable cylinder is connected to the interior of the air collecting plate, and the movable cylinder is vertically inserted into the lower port of the storage tube.

[0013] Optionally, a spring is fixed to the upper end surface of the buffer frame, and the top end of the spring is fixed to the lower end surface of the drone body.

[0014] Optionally, a plurality of parachute ropes are symmetrically mounted on the top end of the umbrella tube, and the top ends of the plurality of parachute ropes are symmetrically mounted on the edges of the unfolded umbrella surface.

[0015] Optionally, a connecting rope connected to the storage tube is installed at the lower end of the blocking plate, and a through hole is opened in the middle of the lower end surface of the blocking plate, and air holes are opened on the surface of the umbrella tube and connected to the through hole in the middle of the lower end surface of the blocking plate.

[0016] Compared with the prior art, the utility model has at least the following beneficial effects:

[0017] In the above scheme, by elastically installing the buffer frame at the lower end of the storage tube, when the drone body is landing, when the two feet at both ends of the buffer frame touch the ground, the buffer frame and the storage tube form a landing buffer through the connection with the spring, thereby reducing the degree of shock to the parts inside the drone body, which is beneficial to reduce the looseness of parts and prolong the service life of the drone.

[0018] At the same time, thanks to the parachute stored in the storage tube and the baffle plate on the upper end surface of the drone body that controls the upper end of the storage tube through the electric telescopic rod to block and limit the parachute, when the drone body falls from a high altitude due to a malfunction, the baffle plate can be retracted by independently controlling the electric telescopic rod, so that when the drone body descends with a heavier buffer frame and standing feet, the airflow can be gathered into the storage tube through the wind gathering plate, the blocking plate is used to make the umbrella tube slide out of the storage tube, and the upward airflow is used to open the umbrella cover, so as to assist the drone body falling from a high altitude to land safely, thereby effectively improving the fall protection of the drone body and having a good use effect.

[0032] like Figure 1 , Figure 2 and Figure 3As shown, an embodiment of the utility model provides a drone protection device including a drone body 1, wherein wings 2 are symmetrically fixed around the drone body 1, and rotor blades 3 are arranged on the wings 2. A vertical mounting tube 4 is passed through the middle of the drone body 1, and a storage tube 5 is detachably installed in the mounting tube 4. Specifically, the outer edge surface of the storage tube 5 is configured with a thread adapted to the inner wall of the mounting tube 4, so that the storage tube 5 is installed in the mounting tube 4 by threaded insertion.

[0033] At the same time, the lower end of the storage tube 5 extends out of the lower end of the mounting tube 4 and is located below the lower end surface of the drone body 1. A buffer frame 6 is elastically mounted on the lower end of the storage tube 5. Standing feet 7 are fixed at both ends of the buffer frame 6 to contact the ground during landing. In specific implementation, a movable cylinder 8 is fixed to the middle of the upper end surface of the buffer frame 6. The movable cylinder 8 is connected to the inside of the wind collecting plate 10. The movable cylinder 8 is vertically inserted into the lower end of the storage tube 5. A spring 9 is fixed to the upper end surface of the buffer frame 6. The top end of the spring 9 is fixed to the lower end surface of the drone body 1, so that the buffer frame 6 and the standing feet 7 are elastically mounted on the lower end surface of the drone body 1.

[0034] like Figure 2 and Figure 4 As shown, a wind collecting plate 10 connected to the storage tube 5 is fixed at the middle of the lower end surface of the buffer frame 6, and an air inlet opening is provided on the lower end surface of the wind collecting plate 10. A parachute 11 is connected to the storage tube 5, and the parachute 11 includes an umbrella tube 1101 vertically stored in the storage tube 5, and an umbrella cover 1104 is installed at the top of the umbrella tube 1101 through a plurality of umbrella ropes 1103, and the umbrella cover 1104 is folded and closely attached to the surface of the umbrella tube 1101. In specific implementation, a plurality of umbrella ropes 1103 are symmetrically installed at the top of the umbrella tube 1101, and the tops of the plurality of umbrella ropes 1103 are symmetrically installed at the edges of the unfolded umbrella cover 1104.

[0035] At the same time, a blocking plate 1102 is fixed to the lower end of the umbrella tube 1101 for blocking the inside of the storage tube 5, and a connecting rope 1106 connected to the storage tube 5 is installed at the lower end of the blocking plate 1102, and a through hole is opened in the middle of the lower end surface of the blocking plate 1102, and an air hole 1105 is opened on the surface of the umbrella tube 1101, which is connected to the through hole in the middle of the lower end surface of the blocking plate 1102, so that the blocking plate 1102 can be received by the upward wind force in the storage tube 5 and slide upward from the top port of the storage tube 5, and in this process, part of the airflow will also be ejected from the air hole 1105 to assist the umbrella cover 1104 to open.

[0036] In addition, a horizontal electric telescopic rod 12 is fixed to the middle part of the upper end surface of the drone body 1, and a baffle 13 is fixed to the shaft of the electric telescopic rod 12. The baffle 13 extends to the port on the mounting tube 4 and limits and blocks the top of the storage tube 5 and the parachute 11. Therefore, the electric telescopic rod 12 can be controlled to retract the baffle 13 to remove the cover from the upper ports of the mounting tube 4 and the storage tube 5, so as to ensure that the parachute 11 slides out from the upper port of the storage tube 5 and unfolds.

[0037] The utility model provides a working principle. When the drone body 1 falls from a high altitude due to a malfunction, the drone protection device can retract the baffle 13 by independently controlling the electric telescopic rod 12, so that when the drone body 1 descends downward with the heavier buffer frame 6 and the standing feet 7, the airflow can be gathered into the storage tube 5 through the wind gathering plate 10, and the blocking plate 1102 is used to make the umbrella tube 1101 slide out of the storage tube 5, and the upward airflow is used to open the umbrella cover 1104, so as to assist the drone body 1 falling from a high altitude to land safely.

[0038] At the same time, when the drone body 1 lands on the ground, the two feet 7 at both ends of the buffer frame 6 will first touch the ground, and the buffer frame 6 and the storage tube 5 will also form a landing buffer through the connection and cooperation with the spring 9, thereby reducing the shock level of the components in the drone body 1, thereby further improving the safety of the drone body 1 during landing, greatly reducing the loss of the drone falling, and having a good use effect.

[0039] The present invention covers any substitution, modification, equivalent method and scheme made on the essence and scope of the present invention. In order to make the public have a thorough understanding of the present invention, specific details are described in detail in the following preferred embodiments of the present invention, and those skilled in the art can fully understand the present invention without the description of these details. In addition, in order to avoid unnecessary confusion about the essence of the present invention, well-known methods, processes, procedures, components and circuits are not described in detail.

[0040] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principle of the present invention. These improvements and modifications should also be regarded as the protection scope of the present invention.
