Description

Technical Field

[0001] This utility model belongs to the field of unmanned aerial vehicle (UAV) surveying technology, and more specifically, it relates to a UAV surveying device that facilitates the adjustment of the camera bracket. Background Technology

[0002] Unmanned aerial vehicle (UAV) mapping is a technology that uses UAVs equipped with sensors, such as cameras, lidar, and multispectral cameras, to collect, process, and analyze geospatial data. Compared with traditional mapping methods, UAV mapping has advantages such as flexibility, efficiency, low cost, and wide coverage, and is widely used in many fields.

[0003] Chinese patent CN220263096U discloses a UAV mapping data acquisition device, relating to the field of UAV mapping technology. The device includes a UAV body. A first fixing plate and a second fixing plate are symmetrically fixedly connected to the lower surface of the UAV body. A fixing block is fixedly connected to the inner wall between the first and second fixing plates. An electric telescopic rod is fixedly connected to the lower surface of the fixing block. A mounting plate is fixedly connected to the lower surface of the electric telescopic rod. A data collector body is movably connected to the lower surface of the mounting plate. A fixing sleeve is fixedly connected to the middle of the lower surface of the data collector body. A first motor is fixedly connected to the inner wall of the fixing sleeve. A first rotating shaft is fixedly connected to the output end of the first motor. A mapping camera body is fixedly connected to the lower surface of the first rotating shaft.

[0004] When changing the overall surveying range, the UAV mapping data acquisition device requires personnel to control the UAV to adjust its direction. This adjustment can easily cause positional deviations, leading to inaccurate surveying data. Furthermore, adjusting the UAV's altitude to change the camera's shooting height is inconvenient and impractical. In the aforementioned document, the first motor drives the mapping camera body to rotate via the first shaft, thereby adjusting the camera's shooting range, which is convenient for use and adjustment. However, when the camera body descends, the left and right supports on the UAV cannot rise accordingly. Additional manual operation is required to rotate the left and right supports to avoid obstructing the camera body, which is cumbersome.

[0005] No effective solutions have yet been proposed to address the problems in the relevant technologies. Utility Model Content

[0006] In view of the problems in the related technologies, this utility model proposes a drone mapping device that is easy to adjust the camera bracket, so as to overcome the above-mentioned technical problems existing in the existing related technologies.

[0007] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0008] This utility model is a drone mapping device that facilitates the adjustment of a camera bracket. It includes a body, a connecting seat fixedly installed at the bottom of the body, a lifting component and a linkage component inside the connecting seat, a support component on the outer surface of the linkage component, and a mapping component on the outer surface of the lifting component. The lifting component is used to push the linkage component and the mapping component to move, and the linkage component is used to make the lifting component drive the support component to rotate.

[0009] Furthermore, the lifting assembly includes a fixed plate, which is fixedly connected inside the connecting seat. An electric push rod is fixedly installed at the bottom of the fixed plate, and a connecting plate is fixedly installed at the movable end of the electric push rod.

[0010] Furthermore, the linkage component includes a rack, which is fixedly connected to a connecting plate. A gear meshes with the outer surface of the rack, and a rotating shaft is fixedly connected to the outer surface of the gear. The rotating shaft is rotatably connected inside the connecting seat, and a rotating plate is fixedly connected to the outer surface of the gear.

[0011] Furthermore, the support assembly includes a rotating rod, which is fixedly connected to a rotating plate. A limiting plate is fixedly connected to the end of the rotating rod. A sliding rod is slidably connected to the outer surface of the rotating rod. A spring is fixedly connected inside the sliding rod and is fixedly connected to the bottom of the limiting plate. An arc groove is formed on the outer surface of the connecting seat, and the rotating rod is slidably connected to the arc groove.

[0012] Furthermore, the mapping component includes a housing, the rack is fixedly mounted on the outer surface of the housing, a first motor is fixedly connected inside the housing, a first rotating seat is fixedly connected to the output shaft of the first motor, the first rotating seat is rotatably connected to the bottom of the housing, a second motor is fixedly connected to the outer surface of the first rotating seat, a second rotating seat is fixedly connected to the output shaft of the second motor, and a camera is fixedly connected to the outer surface of the second rotating seat.

[0013] Furthermore, the outer surface of the rack is provided with a stepped hole, and the internal thread of the stepped hole is connected to a bolt. The rack is fixedly installed on the outer surface of the housing by the bolt.

[0014] Furthermore, a protective plate is fixedly installed on the outer surface of the box.

[0015] This utility model has the following beneficial effects:

[0016] 1. This utility model connects the lifting component and the linkage component. After the lifting component is started, it moves downward and drives the linkage component to work. The linkage component converts the linear motion of the lifting component into rotational motion, causing the support component on the linkage component to rotate. When the lifting component pushes the surveying component down, the support component can avoid the surveying component without additional operation, making it more convenient to use.

[0017] 2. This utility model uses the connection between the sliding rod and the spring. When the sliding rod rotates to the bottom of the connecting seat, the sliding rod contacts the ground first when the machine body descends. Then the machine body pushes the rotating rod and the limiting plate to compress the spring. The friction between the limiting plate and the sliding rod consumes kinetic energy to achieve shock absorption and prevent the machine body from being damaged when it touches the ground.

[0018] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0029] The technical solutions of the utility model embodiments will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the utility model, and not all embodiments. Based on the embodiments of the utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the utility model.

[0030] In the description of this utility model, it should be understood that the terms "opening", "upper", "lower", "top", "middle", "inner", etc., which indicate orientation or positional relationship, are only for the convenience of describing the utility model and simplifying the description, and do not indicate or imply that the components or elements referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the utility model.

[0031] Please see Figures 1-7 As shown, this utility model is a drone mapping device that facilitates the adjustment of the camera bracket. It includes a body 1, a connecting seat 2 fixedly installed at the bottom of the body 1, a lifting component 3 and a linkage component 4 disposed inside the connecting seat 2, a support component 5 disposed on the outer surface of the linkage component 4, and a mapping component 6 disposed on the outer surface of the lifting component 3. The lifting component 3 is used to push the linkage component 4 and the mapping component 6 to move, and the linkage component 4 is used to make the lifting component 3 drive the support component 5 to rotate.

[0032] After the drone is started, the body 1 drives the connecting seat 2 and the mapping component 6 to take off. The lifting component 3 inside the connecting seat 2 is activated, which pushes the linkage component 4 to move. At the same time, the lifting component 3 pushes the mapping component 6 to descend and extend it outside the connecting seat 2. The linkage component 4 drives the support component 5 to rotate so that it avoids obstructing the mapping component 6's field of view.

[0033] This utility model connects the lifting component 3 and the linkage component 4. After the lifting component 3 is started, it moves downward and drives the linkage component 4 to work. The linkage component 4 converts the linear motion of the lifting component 3 into rotational motion, so that the support component 5 on the linkage component 4 rotates. When the lifting component 3 pushes the surveying component 6 down, the support component 5 can avoid the surveying component 6 without additional operation, making it more convenient to use.

[0034] In one embodiment, the lifting assembly 3 includes a fixed plate 301, which is fixedly connected to the inside of the connecting seat 2. An electric push rod 302 is fixedly installed at the bottom of the fixed plate 301, and a connecting plate 303 is fixedly installed at the movable end of the electric push rod 302.

[0035] When the electric push rod 302 is activated, the movable end of the electric push rod 302 can drive the connecting plate 303 to move up and down. The fixing plate 301 is used to provide a fixed position for the electric push rod 302 and fix the movable end of the electric push rod 302 in the connecting seat 2.

[0036] In one embodiment, the linkage component 4 includes a rack 401, which is fixedly connected to a connecting plate 303. A gear 402 meshes with the outer surface of the rack 401. A rotating shaft 403 is fixedly connected to the outer surface of the gear 402. The rotating shaft 403 is rotatably connected inside the connecting seat 2. A rotating plate 404 is fixedly connected to the outer surface of the gear 402.

[0037] The connecting plate 303 drives the rack 401 to move. When the rack 401 moves downward, the rack 401 pushes the gear 402 to rotate through the rotating shaft 403. The rotating plate 404 on the gear 402 rotates accordingly. The rotating shaft 403 is used to support the gear 402.

[0038] In one embodiment, the support assembly 5 includes a rotating rod 501, which is fixedly connected to a rotating plate 404. A limiting plate 502 is fixedly connected to the end of the rotating rod 501. A sliding rod 503 is slidably connected to the outer surface of the rotating rod 501. A spring 504 is fixedly connected inside the sliding rod 503. The spring 504 is fixedly connected to the bottom of the limiting plate 502. An arc groove 505 is formed on the outer surface of the connecting seat 2, and the rotating rod 501 is slidably connected to the arc groove 505.

[0039] Gear 402 drives rotating plate 404 and rotating rod 501 to rotate. Rotating rod 501 slides in sliding groove 505. Rotating rod 501 drives limiting plate 502 and sliding rod 503 to rotate, so that sliding rod 503 rotates from the bottom of connecting seat 2 to the side.

[0040] In one embodiment, the surveying component 6 includes a housing 601, a rack 401 fixedly mounted on the outer surface of the housing 601, a first motor 602 fixedly connected inside the housing 601, a first rotating seat 603 fixedly connected to the output shaft of the first motor 602, the first rotating seat 603 rotatably connected to the bottom of the housing 601, a second motor 604 fixedly connected to the outer surface of the first rotating seat 603, a second rotating seat 605 fixedly connected to the output shaft of the second motor 604, and a camera 606 fixedly connected to the outer surface of the second rotating seat 605.

[0041] When rack 401 moves downward, housing 601 on rack 401 moves downward as well. Camera 606 at the bottom of housing 601 extends beyond connecting seat 2, and rack 401 drives gear 402 to rotate, causing sliding rod 503 to rotate to the side and above camera 606, avoiding interference with the surveying field of view of camera 606. During the surveying process, the angles of first rotating seat 603, second rotating seat 605, and camera 606 are adjusted by rotating first motor 602 and second motor 604. After the surveying is completed, when rack 401 moves camera 606 upward back into connecting seat 2, rack 401 drives sliding rod 503 to rotate to below connecting seat 2. When the machine body 1 lands, shock absorption is achieved through the sliding of sliding rod 503 and spring 504.

[0042] In one embodiment, for the rack 401, a stepped hole 7 is provided on the outer surface of the rack 401, and a bolt 8 is threaded into the stepped hole 7. The rack 401 is fixedly installed on the outer surface of the housing 601 by the bolt 8.

[0043] In one embodiment, for the aforementioned housing 601, a protective plate 9 is fixedly installed on the outer surface of the housing 601.

[0044] The bolt 8 facilitates the disassembly of the housing 601. After removing the housing 601, the protective plate 9 can be opened to maintain the first motor 602 inside the housing 601.

[0045] Through the above technical solution, 1. By connecting the lifting component 3 and the linkage component 4, after the lifting component 3 is started, the lifting component 3 moves downward and drives the linkage component 4 to work. The linkage component 4 converts the linear motion of the lifting component 3 into rotational motion, so that the support component 5 on the linkage component 4 rotates. When the lifting component 3 pushes the mapping component 6 down, the support component 5 can avoid the mapping component 6 without additional operation, which is more convenient to use; 2. By connecting the sliding rod 503 and the spring 504, when the sliding rod 503 rotates to the bottom of the connecting seat 2, when the machine body 1 descends, the sliding rod 503 contacts the ground first. Then the machine body 1 pushes the rotating rod 501 and the limiting plate 502 to compress the spring 504. The friction between the limiting plate 502 and the sliding rod 503 consumes kinetic energy to achieve shock absorption and avoid damage to the machine body 1 when it touches the ground.
