Description

Technical Field

[0001] The utility model relates to the technical field of unmanned aerial vehicle control, in particular to a safe landing deceleration device for unmanned aerial vehicle. Background Art

[0002] The function of the drone safe landing deceleration device is to increase air resistance and reduce the drone's descent speed during the drone's landing process, so that the drone can land smoothly and safely on the ground, effectively preventing the drone from being damaged due to excessively fast landing speed, and at the same time protecting the surrounding environment from safety hazards caused by the drone falling.

[0003] The utility model proposes a deceleration device for safe landing of unmanned aerial vehicles. At present, many unmanned aerial vehicles lack an effective deceleration mechanism during the landing process, which may lead to a series of problems. First, the unmanned aerial vehicle may generate a large impact force on the landing point when descending at a high speed, which may not only damage the structure of the unmanned aerial vehicle itself, but also pose a threat to ground facilities or personnel safety. Secondly, due to the lack of a stable deceleration process, the control system of the unmanned aerial vehicle may find it difficult to accurately control the landing posture, increasing the risk of landing failure. In addition, the lack of deceleration measures may also cause the unmanned aerial vehicle to be unable to respond quickly in an emergency, increasing the probability of accidents.

Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0026] like Figure 1-Figure 3 As shown, this embodiment provides a technical solution: a deceleration device for safe landing of a drone, comprising a deceleration film 1, a shrinkage component 2 is arranged at the bottom of the deceleration film 1;

[0027] The retraction assembly 2 includes a support frame 21, a fixed block 23 is provided on the top, a rotating shaft 24 is provided on the fixed block 23, a rotating shaft 25 is provided on the support frame 21, a rotating shaft 26 is provided at the bottom of the support frame 21, and a retraction rope 22 is provided on the outer side of the support frame 21. One end of the retraction rope 22 is connected to the top of the deceleration film 1, and the retraction rope 22 can be bent and fixed to a certain extent by the fixed block 23 and the rotating shaft 24. The purpose of this design is to make the retraction rope 22 more stable when pulling the equipment and reduce the risk of breakage caused by wear. The support frame 21 can be rotated by the rotating shaft 25 to adjust the bending angle of the equipment. This design can increase the deployment range of the deceleration film 1 and improve the use efficiency of the equipment. The function of the rotating shaft 26 is to bend the retraction rope 22 to make it more flexible when pulling the equipment. This design can effectively protect the retraction rope 22, extend its service life, and solve the technical problem of lack of an effective deceleration mechanism during the landing process.

[0028] Furthermore, Figure 2 and Figure 3 As shown: a connecting assembly 4 is provided on one side of the rotating shaft 25, and the connecting assembly 4 includes a supporting plate 3 44, a supporting plate slot 2 45 is provided on the supporting plate 3 44, and a supporting plate slot 3 46 is provided on the side of the supporting plate 3 44 away from the supporting plate slot 2 45, and a supporting plate 1 41 is provided on the other side of the rotating shaft 25, and a supporting plate 1 42 is provided on the supporting plate 1 41, and a supporting plate 2 43 is provided on the side of the supporting plate 1 41 away from the rotating shaft 25, and the supporting frame 21 can be connected to the rotating shaft 2 25 through the supporting plate slot 1 42 provided on the supporting plate 1 41. This design allows the shaft 26 to smoothly pass through the support plate 1 41, thereby providing a larger downward pressure range when the deceleration film 1 is pulled up. This design is very beneficial for the landing of the UAV and can provide a stable support point for the UAV. At the same time, the support plate slot 25 45 opened on the support plate 3 44 also plays a similar role. It allows the shaft 26 to pass through the support plate 3 44, further increasing the flexibility and adjustability of the equipment. This design not only improves the use efficiency of the equipment, but also ensures the stability of the equipment during use.

[0029] When the above solutions are still in use, the device cannot be installed for different models of drones, such as Figure 4As shown: the support assembly 3 includes a support column 31, a support column slot 32 is opened on the support column 31, a cross bar 33 is arranged on the top of the support column 31, a fixing ring 34 is sleeved on the cross bar 33, a telescopic rod 35 is arranged on the top of the fixing ring 34, a fixing plate 36 is arranged on the top of the telescopic rod 35, and a telescopic plate 37 is arranged between the fixing plates 36. The telescopic plates 37 between the fixing plates 36 can be adjusted by the fixing ring 34. This design enables the device to adapt to drones of different models and sizes. This design not only improves the versatility of the equipment, but also makes the installation process easier. The existence of the telescopic rod 35 further increases the adjustability of the equipment. When installing the drone, the telescopic rod 35 can be used to adjust different heights so that the drone can be stably wrapped inside the device. This design aims to provide better protection for the drone to prevent interference from external factors during flight.

[0030] Working principle:

[0031] like Figure 1 - Figure 4 As shown:

[0032] During use: When the device is installed under the drone, the telescopic plate 37 between the fixing plates 36 can be adjusted through the fixing ring 34, so that the device can be easily installed and adjusted for different drones. This design not only enables the device to adapt to various drones, but also greatly simplifies the installation process. The telescopic rod 35 can be used to adjust the height when installing the drone, so that the drone can be stably wrapped inside the device. This design is intended to provide better protection for the drone to prevent interference from external factors during flight. When the drone is ready to land, one end of the retractable rope 22 is connected to the top of the deceleration film 1, and the retractable rope 22 can be bent and fixed to a certain extent through the fixing block 1 23 and the rotating shaft 1 24. The purpose of this design is to make the retractable rope 22 more stable when pulling the device and reduce the risk of breakage caused by wear. The support frame 21 can be rotated through the rotating shaft 25 to adjust the bending angle of the device. This design can increase the deployment range of the deceleration film 1 and improve the use efficiency of the equipment. The rotating shaft 26 The function is to bend the retraction rope 22, making it more flexible when pulling the equipment. This design can effectively protect the retraction rope 22 and extend its service life. The motor 6 drives the retraction disk 5 to make the retraction disk 5 retract the retraction component 2, so that the retraction rope 22 retracts the retraction component 2 through the support plate slot 1 42 and the support plate slot 3 46, driving the deceleration film 1 to be laid flat. The support plate slot 1 42 opened on the support plate 1 41 can make the support frame 21 rotate under the action of the rotating shaft 25. This design allows the rotating shaft 26 to smoothly pass through the support plate 1 41, thereby providing a larger downward pressure range when the deceleration film 1 is pulled up. Such a design is very beneficial for the landing of the drone because it can provide a stable support point for the drone. The support plate slot 2 45 opened on the support plate 3 44 also plays a similar role. It allows the rotating shaft 26 to pass through the support plate 3 44, further increasing the flexibility and adjustability of the equipment. This design not only improves the use efficiency of the equipment, but also ensures the stability of the equipment during use.
