Description

Technical Field

[0001] This application relates to the field of drone support technology, and more specifically, to a drone-based terrain mapping support device. Background Technology

[0002] Unmanned aerial vehicles (UAVs) are unmanned aircraft controlled by radio remote control equipment and their own program control devices, or operated autonomously by an onboard computer, either completely or intermittently. When equipped with surveying and mapping camera equipment, UAVs can perform remote terrain surveying.

[0003] Currently, drones used for topographic surveying are usually equipped with take-off and landing supports at the bottom of the fuselage. However, some existing drone supports cannot be folded and stored during use, leaving them in an extended state. This increases air resistance during drone flight and makes them more susceptible to collisions with foreign objects, thus increasing safety hazards during flight.

[0004] To address the aforementioned issues, this application provides a terrain mapping support device based on unmanned aerial vehicles (UAVs). Utility Model Content

[0005] The terrain mapping support device based on UAV provided in this application adopts the following technical solution:

[0006] A terrain mapping support device based on a drone includes a drone body. A connecting seat is fixedly connected to the center of the bottom of the drone body. A bidirectional electric actuator is fixedly sleeved through the inner cavity of the connecting seat. A rack plate is fixedly connected to the driving ends on both sides of the bidirectional electric actuator. A rotating rod is provided below one side of each of the two rack plates. The two rotating rods are located below the sides of the drone body. A support leg structure is connected to the outer wall of each end of the rotating rod. A groove is embedded in the outer wall of the middle of the rotating rod, and a lifting arm is rotatably sleeved on the outer wall of the middle of the rotating rod through the groove. The top of each lifting arm is fixedly connected to the outer surface of the bottom of the drone body. A gear is fixedly sleeved on the outer wall of the middle position of the rotating rod. The upper end of the gear meshes with one side of the bottom end of a rack plate. Limiting components are connected to the top of both rack plates.

[0007] Through the above technical solution, the lifting arm and the ring groove realize the rotational lifting and support function of the rotating rod.

[0008] Furthermore, the limiting component includes a rectangular strip located directly above the rack plate. The rectangular strip is fixedly installed on one side of the bottom of the drone body, and a slide rail groove is provided through the middle of the bottom end of the rectangular strip. A slide rail is slidably sleeved on the inner wall of the slide rail groove. The bottom of the slide rail extends out of the interior of the slide rail groove, and the bottom of the slide rail is fixedly connected to the middle position of the top of the rack plate.

[0009] The above technical solution can improve the linear sliding stability of the rack plate.

[0010] Furthermore, the outrigger structure includes a sleeve, the bottom of which is fixedly connected to a base, and a support rod is slidably sleeved through the central inner cavity at the top of the sleeve. The end of the support rod away from the sleeve is fixedly connected to the outer surface of the rotating rod, while the end of the support rod near the sleeve is fixedly connected to a limiting piece, which is slidably sleeved inside the upper end of the sleeve.

[0011] Furthermore, the support leg structure also includes a buffer spring fixedly connected to the bottom of the limiting plate. The bottom of the buffer spring is fixedly connected to the inner wall of the bottom end of the sleeve, and a spring damper is provided on the inner side of the buffer spring. The spring damper is connected at the connection between the bottom of the limiting plate and the inner wall of the bottom end of the sleeve.

[0012] Through the above technical solution, the outrigger structure provides support for the drone body.

[0013] Furthermore, each of the four corners of the outer wall of the drone body is fixedly connected to an arm, and each arm is equipped with a propeller on the side away from the drone body.

[0014] Through the above technical solutions, the arms and propellers enable the drone body to fly.

[0015] Furthermore, a camera frame is fixedly connected to the center of the bottom of the connector, and a surveying camera is rotatably mounted on the inner side of the lower end of the camera frame.

[0016] Using the above technical solutions, the mapping camera can realize the terrain mapping work of the entire drone.

[0017] In summary, this application includes the following beneficial technical effects:

[0018] This application, through the connection seat, bidirectional electric actuator, rack plate, rotating rod, ring groove, hoisting arm, gear, leg structure, and limiting component set at the bottom of the UAV body, can form a support for the take-off and landing of the UAV body for terrain mapping. At the same time, it can realize the automatic folding and storage of the support, and prevent it from being in the unfolded state, which would increase the air resistance during the flight of the UAV, and prevent it from touching foreign objects, which would increase the safety hazards of the UAV flight state.

[0029] Example:

[0030] This application discloses a terrain mapping support device based on a drone. Please refer to [link / reference]. Figures 1-5 The device includes a drone body 1. A connecting seat 2 is fixedly connected to the center of the bottom of the drone body 1. A bidirectional electric push rod 3 is fixedly installed through the inner cavity of the connecting seat 2. A rack plate 4 is fixedly connected to the driving ends on both sides of the bidirectional electric push rod 3. A rotating rod 5 is provided on the lower side of one side of each rack plate 4. The two rotating rods 5 are located on the lower sides of the drone body 1. A support leg structure 6 is connected to the outer wall of both ends of the rotating rod 5. A ring groove 7 is embedded in the outer wall of both sides of the middle of the rotating rod 5. A lifting arm 8 is rotatably sleeved on the outer wall of both sides of the middle of the rotating rod 5 through the ring groove 7. The top of each lifting arm 8 is fixedly connected to the outer surface of the bottom of the drone body 1. A gear 9 is fixedly sleeved on the outer wall of the middle position of the rotating rod 5. The upper end of the gear 9 meshes with one side of the bottom end of a rack plate 4. A limit member is connected to the top of both rack plates 4.

[0031] The limiting component includes a rectangular bar 10 located directly above the rack plate 4. The rectangular bar 10 is fixedly installed on one side of the bottom of the drone body 1, and a slide rail groove 11 is provided through the middle of the bottom end of the rectangular bar 10. A slide rail 12 is slidably sleeved on the inner wall of the slide rail groove 11. The bottom of the slide rail 12 extends out of the interior of the slide rail groove 11, and the bottom of the slide rail 12 is fixedly connected to the middle position of the top of the rack plate 4.

[0032] The outrigger structure 6 includes a sleeve 61, with a base 62 fixedly connected to the bottom of the sleeve 61. A support rod 63 is slidably sleeved through the central cavity of the top of the sleeve 61. The end of the support rod 63 away from the sleeve 61 is fixedly connected to the outer surface of the rotating rod 5, while a limiting piece 64 is fixedly connected to the end of the support rod 63 near the sleeve 61. The limiting piece 64 is slidably sleeved inside the upper end of the sleeve 61. The outrigger structure 6 also includes a buffer spring 65 fixedly connected to the bottom of the limiting piece 64. The bottom of the buffer spring 65 is fixedly connected to the inner wall of the bottom end of the sleeve 61, and the buffer... A spring damper 66 is provided on the inner side of the spring 65. The spring damper 66 is connected to the connection between the bottom of the limiting plate 64 and the inner wall of the bottom end of the sleeve 61. With the cooperation of the sleeve 61, base 62, support rod 63, limiting plate 64, buffer spring 65 and spring damper 66 in each set of support leg structure 6, it is beneficial to the overall landing of the UAV. When each set of support leg structure 6 is used for support work, it achieves a good buffering and shock absorption effect on the landing operation state of the UAV body 1, thereby preventing damage to the UAV body 1 caused by accidental operation and effectively improving its service life.

[0033] Arms 13 are fixedly connected to the four corners of the outer wall of the drone body 1. Each arm 13 is equipped with a propeller 14 on the side away from the drone body 1. A camera frame is fixedly connected to the center of the bottom of the connecting seat 2. A surveying camera 15 is rotatably installed on the inner side of the lower end of the camera frame.

[0034] The implementation principle of this embodiment is as follows: When in use, the UAV body 1 is passively controlled to fly by four sets of arms 13 and propellers 14, while the UAV body 1 performs terrain mapping work through the mapping camera 15 below it, and transmits the video data obtained from the mapping to the control terminal.

[0035] When the entire drone is in flight, the bidirectional electric actuator 3 can drive the rack plates 4 on both sides to move in opposite directions. Due to the meshing state of the rack plates 4 and gears 9, and the fixed engagement state of gears 9 on the outer wall of the middle part of the rotating rod 5, the rotating rods 5 on both sides are indirectly pushed to swing 90 degrees relative to each other. At this time, the four sets of support leg structures 6 fold from a downward vertical state to a storage state parallel to the bottom of the drone body 1, and are distributed in a rectangular shape below the drone body 1. During this process, the rotating rod 5 rotates and engages with the lifting arm 8 through the groove 7, while the lifting arm 8 provides rotational limit support for itself. The rack plates 4 are passively displaced and misaligned with the rectangular bars 10, and then engage with the sliding rails 12 through the sliding rail groove 11. When the entire drone needs to land, the bidirectional electric actuator 3 can drive the rack plates 4 on both sides to move and reset, indirectly causing each set of support leg structures 6 to swing back to a vertical state.

[0036] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
