Technical Field

[0001] The invention relates to an unmanned aerial vehicle, and in particular to an emergency mapping unmanned aerial vehicle with a fall protection function. Background Art

[0002] Emergency mapping drones are unmanned aerial vehicles used to quickly obtain geographic information of disaster-stricken areas after emergencies or disasters. Equipped with high-resolution cameras, LiDAR, infrared sensors and other equipment, these drones can perform tasks in complex and dangerous environments, providing timely and accurate data support for rescue command, disaster assessment, and reconstruction planning.

[0003] During the flight operation of a drone, it may fall due to equipment failure, bad weather, signal interference and other reasons. Once a drone falls, it will not only damage its own equipment and affect the continuity of the data collection task, but also pose a threat to the safety of people and property on the ground. At present, existing surveying and mapping drones have certain shortcomings in fall protection. For example, it is difficult to cope with complex fall situations with a simple buffer structure alone, or there is a lack of targeted protection for key surveying and mapping equipment.

[0004] Therefore, there is an urgent need to develop an emergency mapping UAV with fall protection function to solve the above technical problems. Summary of the invention

[0030] The principle and structure of the present invention are described in detail below with reference to the accompanying drawings and embodiments.

[0031] Embodiment: An emergency mapping drone with fall protection function, such as Figure 1-Figure 5 As shown, it includes a body 1, a camera body 2, a bracket 3, a buffer component 4 and a camera protection component 5. The camera body 2 is fixedly connected to the bottom of the body 1, and the brackets 3 are fixedly connected to the left and right sides of the body 1 by bolts. The buffer component 4 is connected between the bottom ends of the brackets 3, and the camera protection component 5 is connected to the outside of the camera body 2.

[0032] like Figure 3 As shown, the buffer assembly 4 includes a guide rod 41, a buffer ring 42 and a second spring 43. The bottom end of the bracket 3 is installed with a guide rod 41 that can slide vertically. The bottom ends of the guide rods 41 are fixedly connected with the buffer ring 42 by bolts. The second spring 43 is sleeved on the guide rod 41. The top end of the second spring 43 is connected to the bottom end of the bracket 3, and the bottom end of the second spring 43 is connected to the buffer ring 42. The buffer ring 42 is made of flexible material, and the surface of the buffer ring 42 is evenly provided with protective grooves 44.

[0033] like Figure 4 and Figure 5As shown, the camera protection assembly 5 includes a slider 51, a first spring 52, a protective cover 53, a magnet 54, an inclined plate 55, a pressure plate 56 and an air cushion 57. The upper part of the bracket 3 is slidably connected to the slider 51, the first spring 52 is connected between the slider 51 and the bracket 3, the bottom of the slider 51 is connected to the protective cover 53, the protective covers 53 on both sides are close to each other and combined into a closed space to cover the camera body 2, the contacting sides of the protective covers 53 on both sides are provided with magnets 54, the bottom of the protective covers 53 is fixedly connected with the inclined plate 55 by bolts, the inclined plate 55 extends from the connection position to the inner side and downward, the left and right parts of the buffer ring 42 are provided with pressure plates 56, the pressure plate 56 and the inclined plate 55 partially overlap in the vertical direction, and the inner wall of the protective cover 53 is installed with an air cushion 57.

[0034] When the body 1 is working with the camera body 2 and accidentally falls, the buffer ring 42 falls to the ground. Under the action of the second spring 43, the bracket 3 and the device thereon move downward, so that the second spring 43 is compressed to prevent the bracket 3 and the device thereon from directly colliding with the ground. At the same time, the buffer ring 42 is made of flexible material, which can better reduce the damage to the body 1 and the camera body 2. When the bracket 3 and the device thereon move downward, the protective cover 53 is driven to move downward, and then the inclined plate 55 is driven to move downward. When the inclined plate 55 moves downward to contact with the pressure plate 56, the protective cover 53 moves toward the middle, and the magnet 54 attracts the protective covers 53 on the left and right sides together to cover the camera body 2 and protect the camera body 2. At the same time, the air cushion 57 in the protective cover 53 can prevent the camera body 2 from colliding with the protective cover 53, so as to better protect the camera body 2. A protective frame 8 is installed on the rotating blades of the body 1, and the protective frame 8 covers the rotating blades. The protective frame 8 can protect the rotating blades of the body 1.

[0035] like Figure 6 and Figure 7 As shown, it also includes a slow-descent component 6, which is connected between the top of the body 1 and the bracket 3. The slow-descent component 6 includes a connecting frame 61, a mounting cover 62, a flow sensor 63 and a parachute 64. There is a mounting cover 62 on the top of the body 1, and a cover is rotatably connected to the top of the mounting cover 62, and the cover is opened electrically. A parachute 64 is installed in the mounting cover 62, and a flow sensor 63 is installed on the side of the mounting cover 62. The flow sensor 63 can measure the flow speed of the gas and send a signal when it exceeds a preset speed. The top of the guide rod 41 is fixedly connected to the connecting frame 61, and the top of the connecting frame 61 is fixedly connected to the mounting cover 62.

[0036] When the drone falls unexpectedly and rapidly, the flow sensor 63 detects a drastic change in the flow rate of the gas. At this time, the cover on the top of the mounting cover 62 opens, and the parachute 64 opens, which slows down the descent of the fuselage 1 and the devices thereon. At the same time, because the parachute 64 opens, the guide rod 41 and the buffer ring 42 are driven upward through the connecting frame 61, thereby driving the pressure plate 56 to move upward. When the pressure plate 56 moves upward to contact the inclined plate 55, the protective cover 53 can be closed to protect the camera body 2 before the fuselage 1 falls to the ground.

[0037] like Figure 8 and Fig. 9 As shown, an anti-collision component 7 is also included. The anti-collision component 7 is connected between the protective cover 53 and the connecting frame 61. The anti-collision component 7 includes an arc rod 71, a mounting cylinder 72, a blocking plate 73 and a rotating piece 74. The lower part of the connecting frame 61 is provided with an arc rod 71. The side of the protective cover 53 close to the connecting frame 61 is symmetrically provided with a mounting cylinder 72. An airbag is arranged in the mounting cylinder 72. The front outlet of the mounting cylinder 72 is connected to the blocking plate 73 through an axis rotation. The end of the shaft used for rotating the blocking plate 73 is fixedly connected to the rotating piece 74. The rotating piece 74 overlaps with the end of the arc rod 71 in the vertical direction.

[0038] When the parachute 64 is opened and the connecting frame 61 moves upward under the action of the reaction force, the arc rod 71 is driven to move upward. When the arc rod 71 moves upward and contacts the rotating piece 74, the rotating piece 74 is pushed to rotate upward, so that the blocking plate 73 rotates and opens. At this time, the airbag installed in the installation tube 72 is ejected, so that the body 1 and the camera body 2 can be protected when the body 1 collides with the ground. At the same time, if the body 1 falls into the water, the body 1 can be suspended to prevent the body 1 from falling into the water and sinking to the bottom.

[0039] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, it is still possible for those skilled in the art to modify the technical solutions described in the aforementioned embodiments or to make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
