Description

Technical Field

[0001] This application relates to the field of UAV surveying, and more specifically, to a dedicated support structure for oblique photography UAVs. Background Technology

[0002] Oblique photogrammetry involves mounting multiple cameras on an aircraft to simultaneously capture images from different angles, such as vertical and oblique, to obtain more complete and accurate information about ground objects. Currently, oblique photogrammetry technology has wide applications in surveying and mapping, greatly aiding in the creation of realistic geographic models. Oblique photogrammetry is typically conducted using an unmanned aerial vehicle (UAV) platform equipped with oblique cameras.

[0003] The landing gear of existing drones is fixed and does not provide any cushioning protection during takeoff and landing. This causes the drone to vibrate during takeoff and landing, affecting the shooting effect.

[0025] This disclosure will now be described in detail with reference to the accompanying drawings and embodiments.

[0026] A dedicated support structure for an oblique photography UAV includes: a body 1, a rotating frame 3, a support frame 4, a retraction assembly, and a buffer 6; The body 1 is an unmanned aerial vehicle (UAV) and is configured to form a mounting section a1 for mounting a photographic device; the photographic device is an oblique photography 11 device for acquiring three-dimensional modeling influence data; Specifically, the bottom part of the body 1 protrudes to form a connecting block 2, and a fixed roller 21 is fixedly installed on the connecting block 2. The rotating frame 3 has an internal cavity a3, and the fixed roller 21 is inserted horizontally into the cavity a3 so that the rotating frame 3 is mounted on the fixed roller 21 for rotation. The side wall of the rotating frame 3 is connected to the fixed roller 21 through a first torsion spring 31. The torsion spring always provides the rotating frame 3 with a torque to rotate away from the center line of the body 1. More specifically, the support frame 4 has an internal cavity a3 that is connected to the rotating frame 3. The end of the rotating frame 3 is provided with a rotating hole a31, and the two sides of the end of the support frame 4 protrude and are inserted into the rotating hole a31. The side wall of the rotating frame 3 is connected to the rotating hole a31 through a second torsion spring 41, and the second torsion spring 41 always provides the support member with a torque to rotate away from the rotating frame 3. Thus, in the supported state, the rotating frame 3 and the support frame 4 are arc-shaped, which improves the support force. The first torsion spring 31 and the second torsion spring 41 can effectively absorb vibration when the body 1 lands, improving the landing stability.

[0027] Specifically, the fuselage 1 is equipped with a retraction assembly for rotating the rotating frame 3 and the support frame 4 to be directly below the fuselage 1. The retraction assembly allows the fuselage 1 to retract the rotating frame 3 and the support frame 4 to be directly below the fuselage 1 during flight, thereby reducing air resistance and making the flight more stable.

[0028] Specifically, the retractable assembly includes a drive component; the drive component consists of a power source 5, a rotating shaft 51, and a second pull rope 52; A power source component 5, which is a motor, is fixedly mounted on the body 1. A rotating shaft 51 is rotatably mounted on the body 1 and connected to the output shaft of the motor to drive the rotating shaft 51 to rotate. A second pull rope 52 is connected to the side wall of the rotating frame 3, and one end of the second pull rope 52 is connected to the side wall of the rotating shaft 51. Specifically, the side wall of the rotating shaft 51 forms an inlay groove a51 corresponding to the second pull rope 52. The inlay groove a51 extends along the circumferential direction of the rotating shaft 51. A loop for fixing the second pull rope 52 is formed at the end of the inlay groove a51 on the side wall of the rotating shaft 51. When the rotating shaft 51 is driven to rotate, the second pull rope 52 will be wound up along the inlay groove a51. During the winding process, the rotating frame 3 will be pulled to rotate closer to the power source component 5. More specifically, the side wall of the support frame 4 is connected to the rotating frame 3 via a third pull rope 53; when the second pull rope 52 is pulled, the third pull rope 53 will be pulled first to drive the frame to rotate, thereby folding with the support frame 4; preferably, the surface of the rotating frame 3 is recessed to form a groove a53, which extends along the length of the rotating frame 3; a fixed rack 54 is fixedly provided at the bottom of the groove a53, and a moving block 55 is movably provided on the inner wall of the groove a53 above the fixed rack 54; more specifically, the end wall of the groove a53 extends through to the outside to form a through hole; the second pull rope 52 passes through the through hole and is fixedly connected to one end of the moving block 55, so that the second pull rope 52 can pull the moving block 55 to move. Specifically, a sliding rack 56 is movably positioned above the movable block 55; a gear 57 is rotatably mounted on the end of the movable block 55 that is not connected to the second pull rope 52, meshing with the fixed rack 54 and the sliding rack 56; the end of the sliding rack 56 is fixedly connected to the side wall of the support frame 4 via a third pull rope 53; with this configuration, when the movable block 55 is pulled, the sliding rack 56 can move through the action of the gear 57, and the stroke of the movement is twice that of the movable block 55, thus enabling the support frame 4 to flip first, accelerating the retraction and extension speed of the rotating frame 3 and the support frame 4.

[0029] In another preferred embodiment, a buffer 6 is provided at the bottom of the support frame 4, which is an airbag; specifically, an air pressure groove a6 communicating with the airbag is formed inside the support frame 4; wherein, the retraction assembly also includes an inflatable component disposed in the air pressure groove a6. Specifically, the pressurization component consists of a piston 61 and a first elastic element 62; the piston 61 is movably disposed on the inner wall of the air pressure groove a6, initially close to the buffer 6, and when it is close to the buffer 6, the buffer 6 is inflated; the piston 61 is connected to the inner wall of the air pressure groove a6 through the first elastic element 62, which is a spring, and always provides the piston 61 with elasticity when it is close to the buffer 6; More specifically, the piston 61 is provided with a first pull rope 611, which extends along the extension direction of the cavity a3 to the fixed roller 21 and is fixed thereon. When the rotating frame 3 and the support frame 4 are flipped, the curvature of the extension path of the cavity a3 increases, while the length of the first pull rope remains unchanged and is fixed on the fixed roller 21. This causes the piston 61 to move, which allows air to be drawn from the buffer 6, causing the buffer 6 to contract. Conversely, when the support frame 4 is unfolded, the buffer 6 is inflated by the first elastic member 62, filling it with gas. This allows the gas-filled buffer 6 to improve the cushioning effect during descent. In addition, it can also act as a floater when the machine body 1 falls onto the water surface.

[0030] The above description is merely a selection of preferred embodiments of this disclosure and an explanation of the technical principles employed. Those skilled in the art should understand that the scope of the invention involved in the embodiments of this disclosure is not limited to technical solutions formed by specific combinations of the above-described technical features, but should also cover other technical solutions formed by arbitrary combinations of the above-described technical features or their equivalents without departing from the above-described inventive concept.
