Description

Technical Field

[0001] This utility model mainly relates to the field of unmanned aerial vehicle (UAV) technology, specifically a UAV crash protection device. Background Technology

[0002] The drone has no onboard cockpit, but it is equipped with an autopilot, program control devices, and other equipment. Ground personnel, personnel on ships, or at the mothership's remote control station track, locate, remotely control, telemetry, and transmit digital data to it using radar and other equipment. When recovering the drone, it can land automatically in the same manner as a conventional aircraft, or it can be recovered remotely using a parachute or net. It can be reused multiple times and is widely used for aerial reconnaissance, surveillance, communication, anti-submarine warfare, and electronic jamming.

[0003] Currently, when drones in use encounter unexpected situations, the ground is usually unable to control the drone that is about to crash. Existing conventional drones do not have effective protective devices, which can easily cause danger to ground personnel and economic losses. To avoid this, some protective structures or devices for drones have been disclosed in the existing technology. However, most conventional protective devices provide a certain degree of protection around the propeller. When a drone falls to the ground, it will be impacted from the bottom. Traditional mesh protective structures will affect the airflow of the propeller and are not strong enough. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a drone crash protection device. Its main function is to protect the drone propeller structure from impact by installing a rapidly deployable protective structure at the bottom of the propeller. The protective structure can be quickly deployed via a multi-stage folding structure pulled by springs and a control structure that allows for rapid unfolding of the folding structure. The device is integrated into the bottom of the drone through a lightweight and compact design, providing crash protection for the propeller structure.

[0005] To achieve the above objectives, this utility model employs the following technical solution:

[0006] A drone crash protection device includes a drone body, a support rod fixedly arranged around the drone body, a spiral motor fixedly arranged on the upper side of the end of the support rod, a drone propeller fixedly arranged on the upper part of the spiral motor, a support disk fixedly arranged on the bottom side of the end of the support rod, a folding plate storage box support plate fixedly arranged on one side of the support disk, inclined support columns fixedly arranged on both sides of the bottom of the support disk, a support block fixedly arranged at the bottom of the inclined support columns, a folding plate storage box fixedly arranged at the bottom of the folding plate storage box support plate, and a bolt plate fixedly arranged on the inner end of the folding plate storage box to be fixedly connected to the drone body.

[0007] Furthermore, the folding plate storage box has a slider inside which it slides. Folding fan blade support plates are fixed on both sides of the slider end. Folding fan blade support plates have holes for folding fan blade pivot rods on their surfaces. A folding fan blade pivot rod is installed inside the upper hole of the folding fan blade pivot rod, and a bolt is installed inside the lower hole of the folding fan blade pivot rod for threaded connection with the pivot rod. A fixed folding plate is fixedly sleeved in the middle of the pivot rod. Spring folding plates are sleeved on the upper and lower sides of the pivot rod and rotatably connected to it. A rotating plate is provided between the fixed folding plate and the spring folding plate, which is sleeved on the outer periphery of the pivot rod and rotatably connected to it. A connecting strip is fixedly connected between the fixed folding plate, the spring folding plate, and the rotating plate.

[0008] Furthermore, the bottom of the folding panel storage box is provided with a sliding column groove, and the bottom of the slider is fixedly provided with a sliding column installed inside the sliding column groove and slidably connected thereto. A spring column is provided on the outside of the sliding column groove and is fixedly connected to the folding panel storage box. A tension spring is fixedly connected on the inside of the spring column, and the end of the tension spring is fixedly connected to the sliding column. A limiting column hole is fixedly provided at the bottom of the slider, and a limiting column controller is fixedly provided at the bottom of the folding panel storage box. A limiting column is provided inside the limiting column controller and slidably connected thereto. The limiting column can pass through the sliding column groove and be inserted into the limiting column hole.

[0009] Compared with the existing technology, the beneficial effects of this utility model are:

[0010] A protective structure that can be quickly deployed is installed at the bottom of the drone propeller to protect the propeller structure from falling to the ground. The protective structure can be quickly deployed by using a multi-stage folding structure that is pulled by springs and a control structure that can be controlled to quickly deploy the folding structure. The device is integrated into the bottom of the drone through a lightweight and compact design, providing fall protection for the propeller structure. Attached Figure Description

[0023] Example: A drone crash protection device

[0024] like Figure 1-7 As shown, a drone crash protection device has the following specific structure:

[0025] A drone crash protection device includes a drone body 1, a support rod 2 fixed around the drone body 1, a spiral motor 3 fixed to the upper side of the end of the support rod 2, a drone propeller 4 fixed to the upper part of the spiral motor 3, the spiral motor 3 drives the drone propeller 4 to rotate, thereby providing lift to the drone body 1 and controlling the flight direction, a support disk 5 fixed to the bottom side of the end of the support rod 2, a folding plate storage box support plate 6 fixed to one side of the support disk 5, inclined support columns 7 fixed to both sides of the bottom of the support disk 5, a support block 8 fixed to the bottom of the inclined support column 7 for supporting the structure, a folding plate storage box 9 fixed to the bottom of the folding plate storage box support plate 6, and a bolt plate 10 fixed to the inner end of the folding plate storage box 9 for fixed connection with the drone body 1.

[0026] The folding plate storage box 9 has a slider 11 inside, which slides 12 with the slider 11. Folding fan blade support plates 13 are fixed on both sides of the end of the slider 11. The surface of the folding fan blade support plate 13 has a folding fan blade pivot hole 14. The upper part of the folding fan blade pivot hole 14 is provided with a folding fan blade pivot rod 15. The lower part of the folding fan blade pivot hole 14 is provided with a bolt 16 for threaded connection with the folding fan blade pivot rod 15. A fixed folding plate 17 is fixedly sleeved in the middle of the folding fan blade pivot rod 15. Spring folding plates 17 are sleeved on the upper and lower sides of the folding fan blade pivot rod 15. 8 is rotatably connected to it, and the spring-loaded folding plate 18 has an elastic structure inside to provide rotational force for it to rotate to both sides. A rotating plate 19 is provided between the fixed folding plate 17 and the spring folding plate 18 and is sleeved on the outer periphery of the folding fan blade shaft 15 and rotatably connected to it. A connecting strip 20 is fixedly connected between the fixed folding plate 17, the spring folding plate 18 and the rotating plate 19. By rotating the spring folding plate 18 to both sides, the connecting strip 20 and the rotating plate 19 connected to it are pulled to unfold, thereby protecting the UAV propeller 4.

[0027] The bottom of the folding panel storage box 9 has a sliding groove 21. A sliding post 22 is fixedly installed inside the sliding groove 21 and slidably connected to the bottom of the slider 11. A spring post 23 is fixedly connected to the outside of the sliding groove 21 and to the folding panel storage box 9. A tension spring 24 is fixedly connected to the inside of the spring post 23, and the end of the tension spring 24 is fixedly connected to the sliding post 22. A limiting post hole 25 is fixedly provided at the bottom of the slider 11, and a limiting post controller 26 is fixedly provided at the bottom of the folding panel storage box 9. The limiting post controller 26 has a limiting post 27 slidably connected to it. The limiting post 27 can pass through the sliding post groove 21 and be inserted into the limiting post hole 25. The tension spring 24 pulls the sliding post 22, causing the slider 11 to move outward inside the folding plate storage box 9. The limiting post 27 is inserted into the limiting post hole 25 to limit the slider 11. Furthermore, the limiting post controller 26 can be controlled to retract the limiting post 27 to release the limitation on the slider 11.

[0028] This solution also includes a controller, the location of which is set by the operator according to the actual situation during operation. The controller is used to control the electrical components used in this solution, including but not limited to sensors, motors, telescopic rods, water pumps, solenoid valves, heating wires, heat pumps, displays, computer input devices, switches, communication devices, lights, speakers, and microphones. The controller is an Intel processor, AMD processor, PLC controller, ARM processor, or microcontroller. It is used in conjunction with a motherboard, memory modules, storage media, and power supply, which is AC power or a lithium battery. When a display screen is provided, a graphics card is also included. For the operating principle of the controller, please refer to "Principles of Automatic Control," "Microcontroller Principles and Application Simulation Cases," and "Sensor Principles and Applications" published by Tsinghua University Press. Other books in this field can also be consulted. Other automation control and electrical components not mentioned are knowledge well known to those skilled in the art and will not be described in detail here.

[0029] Working principle:

[0030] In use, this device first controls the spiral motor 3 to drive the drone propeller 4 to rotate, thereby driving the drone body 1 to ascend, descend, and control flight. When the device accidentally falls, in the state of imminent landing, the limit post controller 26 retracts the limit post 27 to pull it out of the limit post hole 25, causing the slider 11 to enter the active state. Then, the tension spring 24 pulls the slider 11 to move outward, thereby driving the spring folding plate 18 and the rotating plate 19 to move outward. The spring folding plate 18 is detached from the support of the folding plate storage box 9 and further rotated to one side by the internal spring structure of the spring folding plate 18. The upper and lower spring folding plates 18 rotate to the sides respectively, pulling the connecting strip 20 to unfold. The inclined support column 7 limits the spring folding plate 18, and the spring folding plate 18 pulls the rotating plate 19 to unfold, forming a protective structure to protect the bottom of the drone propeller 4 after the device falls to the ground.
