Description

TECHNICAL FIELD

[0001] The present application belongs to the technical field of unmanned aerial vehicle accessory calibration equipment, and particularly relates to a posture correction tool for a damping cabin body of an unmanned aerial vehicle. BACKGROUND

[0002] When an unmanned aerial vehicle performs high-precision tasks such as aerial photography, surveying and reconnaissance, the camera and sensor equipment carried by the unmanned aerial vehicle are installed in a damping cabin body with damping and stabilizing functions. In order to ensure that these loads can obtain accurate data and high-quality images, the posture, especially the pitch angle, of the damping cabin body must be regularly and accurately calibrated on the ground.

[0003] When performing such calibration operations, an auxiliary tool, i.e., a tool, is needed to stably fix the calibrated damping cabin body at a certain specific tilt angle. Some existing tools only provide a fixed slope and adjust the angle through a simple hinge structure. However, this simple structure has some deficiencies in actual application. For example, the adjustment method using an ordinary hinge combined with friction locking makes it difficult to finely adjust the angle. When an operator tries to set the cabin body at an accurate target angle, it is found that due to the structural gap and displacement during locking, it is difficult to reach the target angle at one step, and repeated attempts are needed, which greatly affects the calibration efficiency. After a damping cabin body with a certain weight is placed on the adjustment platform, the structure locked only by friction will slowly creep and slide in the angle after being subjected to external vibration and long-term placement, resulting in a change in the calibration reference, thereby affecting the accuracy and reliability of the calibration result.

[0004] Therefore, how to design a posture correction tool for a damping cabin body of an unmanned aerial vehicle that can achieve high-precision, labor-saving fine adjustment and provide long-term, stable and reliable angle locking has become a technical problem to be solved in the field.

[0026] Reference Figure 3, the rotating disc 9 is also threadedly connected with a fastening screw 11, the end of the fastening screw 11 abuts against the support body 12, for locking the rotating disc 9 after adjustment; when the adjusting handle 10 drives the adjusting shaft 8 to adjust the mounting platform 6 to a predetermined angle, the fastening screw 11 is tightened, the end will exert pressure on the surface of the support body 12, thereby locking the rotating disc 9 through the huge static friction, and further locking the adjusting shaft 8 as a worm, in addition to the transmission self-locking characteristics of the worm gear mechanism itself, this structure increases a physical hard lock, completely eliminates any small angle changes caused by vibration or heavy load, greatly improves the reliability of angle locking.

[0027] With reference to Figure 3 The fastening screw 11 is a hand screw with knurled head, facilitating tool-free operation.

[0028] With reference to Figure 2 Further comprising a rotating plate 5 fixedly arranged on the outer wall of the support body 12, the rotating shaft part penetrates the rotating plate 5; the arrangement of the rotating plate 5 increases the combination area and support span of the support body 12 and the rotating shaft part of the scale pointer 4, the rotating shaft part of the scale pointer 4 penetrates the rotating plate 5, so that the support body 12, the rotating plate 5 and the mounting platform 6 form a more solid overall structure, effectively resisting the bending moment or torsional deformation that may be generated when the unmanned aerial vehicle cabin 18 is carried, ensuring the smoothness of the angle adjustment process and the accuracy of the final angle retention capability.

[0029] With reference to Figure 1 Or Figure 4The coarse adjustment mechanism comprises at least three support leg assemblies arranged at the bottom of the support base 1, each support leg assembly comprises a connecting frame 13 rotatably arranged at the bottom of the support base 1, the rotatable connection enables the plurality of connecting frames 13 to be spread outwards with the support base 1 as the center, forming a stable triangular or polygonal support structure, and a sliding block 14 is slidably connected to the outer wall of each connecting frame 13, the inner wall of the sliding block 14 is matched with the outer wall of the connecting frame 13, so that the sliding block 14 can move up and down along the length direction of the connecting frame 13, thereby changing the effective length of the entire support leg. In order to reliably fix the length of the support leg, a fastening screw 17 is threadedly connected to each sliding block 14, when the position of the sliding block 14 on the connecting frame 13 is adjusted, the fastening screw 17 is tightened, the end of the fastening screw 17 abuts against the outer wall of the connecting frame 13, and the sliding block 14 is fixed in position through friction, preventing accidental sliding during use, and ensuring the height stability of the entire tool and the state after leveling. At the end of the support leg, the bottom of each sliding block 14 is fixedly connected with a sliding base 15, the sliding base 15 further increases the contact base with the ground and serves as a connecting transition piece, the bottom outer wall of the sliding base 15 is clamped and connected with the top inner wall of a foot base 16, and the foot base 16 serves as a component directly contacting the working plane and usually has a bottom surface with increased friction, so that the entire tool is not easy to slide when placed, and through independent length adjustment of the plurality of support leg assemblies, the unmanned aerial vehicle damping cabin body posture correction tool can also realize the horizontal of the support base 1 on uneven ground.

[0030] Reference Figures 2 to 3 The mounting platform 6 is preferably a flat bearing surface, providing uniform support for the bottom of the unmanned aerial vehicle cabin body 18, and mounting frames 7 are fixedly connected around the outer wall of the mounting platform 6, the mounting frames 7 are preferably L-shaped flange structures, and the plurality of mounting frames 7 jointly enclose a containing space matched with the outer shape of the bottom of the unmanned aerial vehicle cabin body 18, when the unmanned aerial vehicle cabin body 18 is placed on the mounting platform 6, the mounting frames 7 can be effectively limited from all directions to prevent sliding or displacement during angle adjustment or calibration, ensuring the stability of the calibration reference.

[0031] The working principle of the present application is as follows: Working principle: before the posture correction work, first of all, the erection and leveling of tooling, the plurality of foot base 16 is placed on the work plane, according to the ground flatness and the required working height, manual adjustment of the plurality of sliding block 14 on the corresponding connecting frame 13 on the sliding position, so as to change the length of each support leg, when the support chassis 1 is adjusted to the horizontal state, respectively, tighten the fastening screw two 17 on each sliding block 14, fastening screw two 17 by exerting pressure to lock the sliding block 14 on the connecting frame 13 firmly, prevent height change, at this time, by the support chassis 1, connecting frame 13, sliding block 14, sliding base 15 and foot base 16 together constitute the base assembly, for the upper adjusting mechanism provides a stable and reliable horizontal reference.

[0032] After the preparation work is ready, the unmanned aerial vehicle cabin 18 to be calibrated is placed on the installation platform 6, the bottom of the unmanned aerial vehicle cabin 18 is stably limited by the installation frame 7 around, to prevent displacement in the subsequent operation, when it is needed to adjust the unmanned aerial vehicle cabin 18 to a certain pitch angle for calibration, the operator starts to rotate the adjusting handle 10, the rotation of the adjusting handle 10 will synchronously drive the rotation of the rotating disc 9 fixedly connected with it, and in turn drive the adjusting shaft 8 fixedly connected with the rotating disc 9 to rotate inside the support main body 12.

[0033] The adjusting shaft 8, as the power input end of the whole core transmission mechanism, is a worm, the threads on the outer wall of the adjusting shaft 8 and the gear structure on the rotating shaft part of the scale pointer 4 as the worm wheel form precise meshing transmission, therefore, the rotation of the adjusting shaft 8 will stably drive the precise, small amplitude rotation of the rotating shaft part of the scale pointer 4 with a large reduction ratio, since the support main body 12, the rotating plate 5 and the installation platform 6 bearing the unmanned aerial vehicle cabin 18 are all fixedly connected to the rotating shaft part of the scale pointer 4, forming an indivisible rigid rotating whole, so the rotation of the rotating shaft part will drive the whole support main body 12 assembly to tilt around the central axis of the rotating shaft part relative to the fixed scale support seat 2.

[0034] During the whole angle adjustment process, with the rotation of the support body 12, the pointer end of the scale pointer 4 fixed thereon will synchronously sweep the adjustment angle scale 3 on the outer wall of the scale support seat 2, so that the accurate inclination angle of the installation platform 6 can be observed in real time and intuitively, when the posture of the installation platform 6 reaches the target angle required for calibration, the operator stops rotating the adjustment handle 10, at this time, due to the inherent reverse self-locking characteristics of the worm gear transmission mechanism, even if the moment is exerted on the installation platform 6 by the gravity of the UAV cabin body 18, the angle of the installation platform 6 will be stably maintained and will not be reversed or slipped, in order to further ensure the absolute reliability of the locking, the fastening screw I 11 arranged on the rotating disc 9 is screwed, the end of the fastening screw I 11 abuts against the support body 12, and by exerting a physical locking force, the possibility of any rotation of the rotating disc 9 and the adjustment shaft 8 is completely eliminated, so that double high-strength locking of the posture angle is realized, finally, through the cooperation of the above-mentioned parts, the unmanned aerial vehicle cabin body 18 can be stably and accurately fixed at any preset posture for high-precision posture calibration work.
