Description

Technical Field

[0001] This utility model belongs to the field of drone accessory technology, and more specifically, it relates to a mounting bracket for aerial photography drones. Background Technology

[0002] With the rapid development of drone technology, aerial photography drones are increasingly being used in fields such as film and television shooting, geographic surveying, and agricultural monitoring. In practical applications, the stability and adjustability of the drone's mounted equipment (such as cameras and sensors) directly affect the operational results.

[0003] Traditional mounting racks typically employ a fixed structure or a single-dimensional angle adjustment design, which has the following drawbacks:

[0004] 1. Most mounts do not allow for adjusting the distance between the equipment and the drone, making it difficult to adapt to the different shooting scenarios' requirements for field of view height;

[0005] 2. The inability to adjust angles in multiple dimensions limits the diversity of shooting perspectives.

[0006] Therefore, in view of this, we have studied and improved the existing structure and its shortcomings, and provided a drone mounting bracket for aerial photography in order to achieve a more practical purpose. Utility Model Content

[0007] To solve the above-mentioned technical problems, this utility model provides an aerial photography drone mounting bracket, which is achieved by the following specific technical means:

[0008] A drone mounting bracket includes a support plate. Rectangular tubes are mounted at each of the four corners of the upper end of the support plate. A sliding rod is slidably mounted within each rectangular tube for adjusting the height of the support plate. Hinges are rotatably mounted at each of the four corners of the upper end of the support plate. The bottom end of each sliding rod is located within a hinge joint, and hinge shafts are fixedly connected to both sides of the bottom end of each sliding rod. Each sliding rod is hinged to the hinge joint via the hinge shafts for adjusting the tilt angle of the support plate. A mounting plate is rotatably mounted at the top of each rectangular tube, and mounting holes are provided on the upper surface of each mounting plate for connecting to the drone.

[0009] Furthermore, each of the slide rods has several fixing holes equidistantly distributed on its surface. The fixing holes are distributed along the height of the slide rod. Each of the rectangular tubes has a bolt 2 that matches the fixing hole 2 screwed in, which is used to lock the position of the slide rod.

[0010] Furthermore, each of the four corners of the bottom of the bearing plate is provided with a circular plate, and each hinge joint is fixedly connected to the circular plate with a through shaft, and each through shaft movably passes through the bearing plate.

[0011] Furthermore, each of the four corners of the bottom surface of the bearing plate is provided with a set of fixing holes, and each set of fixing holes consists of two holes. Each circular plate is screwed into a bolt that matches the fixing hole to lock the position of the hinge joint.

[0012] Furthermore, a circular groove is formed in the center of the bottom surface of each mounting plate, and an annular groove is formed on the side wall of each circular groove.

[0013] Furthermore, each of the circular grooves is provided with a cylinder, and each cylinder is fixedly fitted with a ring on its outer wall. Each ring is located in the annular groove, and each cylinder is fixedly installed at the middle of the top of the rectangular tube.

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] First, the slide bar can slide flexibly along the rectangular tube. Combined with the equidistant fixing holes on the slide bar, the corresponding hole position can be precisely selected and the height locked according to the size of the mounted equipment (such as aerial camera, sensor). This avoids interference between the equipment and the drone body and prevents altitude deviation caused by flight vibration. During adjustment, only the four slide bars need to be controlled to move synchronously, making the operation simple and efficient.

[0016] 2. Supports forward and backward, left and right tilt adjustment; forward and backward tilt is achieved by controlling the difference in the extension length of the front and rear side sliders, which can meet the needs of aerial photography such as looking down (shooting ground details) and looking up (shooting aerial scenery); left and right tilt requires first rotating the hinge joint to switch the direction of the hinge axis, and then adjusting the difference in the length of the left and right side sliders, which is suitable for side shooting scenarios such as slopes and rivers; after adjustment, the tilt angle is locked by bolts, which makes the aerial shooting image less skewed.

[0017] 3. The mounting plate is fitted with a cylindrical and ring-shaped structure at the top of the rectangular tube through a circular groove, which not only prevents it from falling off but also allows it to rotate freely, avoiding rigid pulling when the UAV turns. The coaxial design of the cylinder and the through shaft can prevent component interference when adjusting the hinge joint. The multi-node locking (one bolt locks the hinge joint, and the other bolt locks the slide bar) ensures that the mounting frame is not easy to loosen even in high-speed flight or complex airflow, thus ensuring equipment safety.

[0027] Example:

[0028] As attached Figure 1 To be continued Figure 4 As shown:

[0029] This utility model provides a mounting bracket for an aerial photography drone, including a support plate 1. Rectangular tubes 2 are installed at the four corners of the upper end of the support plate 1. A sliding rod 3 is slidably installed inside each rectangular tube 2 for adjusting the height of the support plate 1. Hinges 4 are rotatably installed at the four corners of the upper end of the support plate 1. The bottom end of each sliding rod 3 is located inside the hinge 4, and hinge shafts 32 are fixedly connected to both sides of the bottom end of each sliding rod 3. Each sliding rod 3 is hinged to the hinge 4 via the hinge shafts 32 for adjusting the tilt angle of the support plate 1. A mounting plate 5 is rotatably installed at the top of each rectangular tube 2, and a mounting hole 51 is provided on the upper surface of each mounting plate 5 for connecting to the drone.

[0030] Each slide rod 3 has several fixing holes 31 evenly spaced on its surface. The fixing holes 31 are distributed along the height direction of the slide rod 3. Each rectangular tube 2 has a bolt 21 that matches the fixing hole 31, which is used to lock the position of the slide rod 3.

[0031] A circular plate 41 is provided at each of the four corners of the bottom of the bearing plate 1. A through shaft 42 is fixedly connected between each hinge joint 4 and the circular plate 41. Each through shaft 42 movably passes through the bearing plate 1.

[0032] Each of the four corners of the bottom of the bearing plate 1 is provided with a set of fixing holes 11. There are two fixing holes 11 in each set. Each circular plate 41 is screwed into a bolt 43 that matches the fixing hole 11 at the bottom, which is used to lock the position of the hinge joint 4.

[0033] A circular groove 52 is provided in the middle of the bottom surface of each mounting plate 5, and an annular groove 53 is provided on the side wall of each circular groove 52.

[0034] Each circular groove 52 contains a cylinder 54, and each cylinder 54 has a ring 55 fixedly fitted on its outer wall. Each ring 55 is located in an annular groove 53. Each cylinder 54 is fixedly installed at the middle of the top of the rectangular tube 2. The cylinder 54 and the through shaft 42 are on the same axis. The coaxial design avoids interference with the movement of the mounting plate 5 when adjusting the hinge joint 4.

[0035] The working principle of this embodiment:

[0036] Mounting plate 5 is the connecting carrier between the mount and the drone. The circular groove 52 in the middle of its bottom surface and the cylinder 54 at the top of the rectangular tube 2 form a nested fit. At the same time, the ring 55 on the outer wall of the cylinder 54 is inserted into the annular groove 53 on the side wall of the circular groove 52. This structure not only restricts the axial displacement of mounting plate 5 and rectangular tube 2 (to prevent detachment), but also allows mounting plate 5 to rotate freely around cylinder 54. The mount is connected to the bottom of the drone with bolts or other fasteners through the mounting holes 51 on the upper surface of mounting plate 5.

[0037] The sliding rod 3 and the rectangular tube 2 are in a sliding fit relationship (the sliding rod 3 can move up and down along the inner wall of the rectangular tube 2). The top of the sliding rod 3 is indirectly fixed to the drone through the mounting plate 5. Therefore, the sliding of the sliding rod 3 will directly change the distance between the support plate 1 (the mounting equipment placement platform) and the bottom of the drone. When the support plate 1 needs to be raised, pull the support plate 1 upward, and drive the rectangular tube 2 to slide upward along the sliding rod 3. When the support plate 1 needs to be lowered, press the support plate 1 downward, and make the rectangular tube 2 slide downward along the sliding rod 3. Tighten the bolt 21 on the side wall of the rectangular tube 2 clockwise into the fixing hole 31 on the surface of the sliding rod 3 (the fixing hole 31 is evenly distributed along the height direction of the sliding rod 3, and the corresponding height hole position can be selected). Through the clamping action of the bolt 21 and the fixing hole 31, the relative position of the sliding rod 3 and the rectangular tube 2 is locked to avoid height deviation. When adjusting the height, the height of the four sliding rods 3 moving down or up must be consistent.

[0038] Forward and backward tilt adjustment: Two front rectangular tubes 2 are installed at the two front corners of the upper end of the support plate 1, and two rear rectangular tubes 2 are installed at the two rear corners. The forward and backward tilt of the support plate 1 is achieved by controlling the difference in the length of the front slide rod 3 and the rear slide rod 3 extending out of the rectangular tube 2. If the support plate 1 is required to be "high at the rear and low at the front" (such as the downward angle of aerial photography), the extension length of the front slide rod 3 is made less than the extension length of the rear slide rod 3. If the support plate 1 is required to be "high at the front and low at the rear" (such as the upward angle of aerial photography), the opposite adjustment is made so that the extension length of the front slide rod 3 is greater than the extension length of the rear slide rod 3. After adjusting to the target tilt angle, the bolts 21 on the front and rear rectangular tubes 2 are screwed into the fixing holes 31 of the corresponding slide rods 3 one by one to lock the position of each slide rod 3 and ensure that the forward and backward tilt angle is stable.

[0039] In the initial state, the hinge shaft 32 is in the "front-back direction" and cannot tilt left or right. It is necessary to first rotate the hinge joint 4 to change the direction of the hinge shaft 32, and then adjust the tilt by the difference in the extension lengths of the left and right slide rods 3. First, loosen the bolts 43 on the four corner round plates 41 at the bottom of the bearing plate 1 (the bolts 43 are initially screwed into the fixing holes 11 of the bearing plate 1 to lock the position of the hinge joint 4), allowing the hinge joint 4 to rotate around the through shaft 42 (the connecting shaft between the hinge joint 4 and the round plate 41, which movably passes through the bearing plate 1). Rotate each hinge joint 4 90 degrees clockwise or counterclockwise around the through shaft 42, so that the hinge shaft at the bottom of the slide rod 3... 32 is changed from "front-back direction" to "left-right direction"; then, bolt 43 is re-screwed into the corresponding fixing hole 11 at the bottom of the bearing plate 1 (each set of fixing holes 11 contains two, to meet the locking requirements of the hinge joint 4 before and after rotation), locking the direction of the hinge joint 4 to prevent the hinge shaft 32 from shifting during subsequent adjustment; the left and right tilting direction of the bearing plate 1 is adjusted by the difference in the extension length of the left and right slide rods 3; after the adjustment is up to standard, bolts 21 on the left and right rectangular tubes 2 are screwed into the corresponding fixing holes 31 of the slide rods 3 one by one to lock the position of the slide rods 3 inside the rectangular tubes 2, ensuring that the left and right tilting angles do not shift due to vibration.
