Description

Technical Field

[0001] This utility model relates to the field of drone brackets, specifically a drone flat bracket. Background Technology

[0002] When drones perform missions in complex terrain environments (such as mountains, ruins, and wilderness), they often face the challenge of taking off and landing on uneven ground. Traditional fixed landing gear designs are based on the assumption of flat ground, and their rigid structures and fixed support points are difficult to adapt to differences in ground height, slopes, or local bumps / indentations. When a drone lands, if the contact points between the landing gear and the ground cannot distribute the load evenly, it may cause problems such as imbalance of the center of gravity and concentrated impact force.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figures 1 to 5This utility model provides a technical solution: a drone leveling bracket, including a drone 1 and a triangular bracket 2. The triangular bracket 2 is installed below the drone 1. A boom 3 is provided directly below the drone 1. A balance ring 4 is connected to the bottom of the boom 3. The balance ring 4 can rotate freely below the boom 3 to maintain horizontality. The triangular bracket 2 includes three equally spaced legs. Each leg includes a pipe leg 1 21 and a leg 22 that can slide relative to each other. The upper end of the pipe leg 1 21 is slidably connected to the leg 22. An electric actuator 23 is provided in the leg 22. The output shaft of the electric actuator 23 is connected to the top of the pipe leg 1 21. When the drone 1 lands, it is supported by the triangular bracket 2. When the bottom surface is uneven, the extension and retraction of the pipe leg 1 21 driven by the electric actuator 23 makes the drone 1 level again.

[0023] In this embodiment, the suspension rod 3 is located at the center of the triangular bracket 2. The lower end of the suspension rod 3 is provided with a ball joint 31. The center of the balance ring 4 is provided with a joint sleeve 41. The joint sleeve 41 is connected to the ball joint 31 and the two can slide freely. The joint sleeve 41 is connected to the inner side of the ring 43 through a support plate 42. The outermost end of the support plate 42 is provided with a photoelectric switch 44. Through the sliding connection between the ball joint 31 and the joint sleeve 41, the balance ring 4 is always kept horizontal under the action of gravity. At the same time, the balance ring 4 is a ring with uniform mass distribution.

[0024] In this embodiment, the bottom of the support leg 21 is provided with a buffer sleeve 211, and a pressure switch 212 is provided inside the buffer sleeve 211. The pressure switch 212 is used to control the power supply and de-energization of the electrical components in the entire triangular support 2 and the balance ring 4. When the drone takes off, the pressure switch 212 is not under pressure, and all electrical components are de-energized to avoid consuming the power of the drone. After landing, all electrical components are energized and the drone begins to adjust its state.

[0025] In this embodiment, a signal reflector 221 facing the balance ring 4 is provided on the side wall of the second support 22. A photoelectric switch 222 is provided below the signal reflector 221. The electric push rod 23 is installed in the second support 22 through a mounting ring. The electric push rod 23 is electrically connected to the first photoelectric switch 44. When the first photoelectric switch 44 shines on the signal reflector 221, it controls the electric push rod 23 to work. When the first photoelectric switch 44 shines on the second photoelectric switch 222, it controls the electric push rod 23 to stop working. When it shines on the second photoelectric switch 222, it does not start the electric push rod 23.

[0026] Working principle: When the drone 1 takes off, all electrical components are powered off, and all legs 1 21 are retracted into legs 22, keeping all legs in their shortest possible state to prevent them from snagging on obstacles during flight. When landing on uneven ground, if any one or two legs tilt, the balance ring 4 will rotate around the ball joint 31 under the action of gravity and eventually return to a horizontal state. Then, because of the tilt, the signal reflectors 221 on some legs 22 will be illuminated by photoelectric switches 1 44. At this time, the electric push rod 23 inside the leg is activated, causing the electric push rod 23 to push the legs 1 21 outward until the photoelectric switches 222 and 44 receive signals from each other. The electric push rod 23 stops, that is, all the photoelectric switches 1 44 and 222 are facing each other, which can keep the drone 1 back in a level state.

[0027] Based on the above, this utility model is equipped with a balance ring that can always maintain a horizontal state. The electric push rod is stopped by the electrical signal between photoelectric switch one and photoelectric switch two on the balance ring. The electric push rod is started by the electrical signal between photoelectric switch one and signal reflector to push the support leg one until the three support legs reach the same horizontal state as the balance ring, thereby realizing the flat parking of the drone on uneven ground.

[0028] As is known from common technical knowledge, this utility model can be implemented through other embodiments that do not depart from its spirit or essential characteristics. Therefore, the disclosed embodiments described above are merely illustrative in all respects and are not the only ones. All modifications within the scope of this utility model or its equivalents are included in this utility model.
