Description

Technical Field

[0001] This utility model relates to the field of drone landing gear technology, specifically a mechanism for locking drone landing gear. Background Technology

[0002] The landing gear of a drone is a crucial component ensuring its safe takeoff and landing. It is typically mounted on the bottom of the fuselage and comes in various structures, including fixed and retractable types. Fixed landing gear is simple in structure and low in cost, providing stable support for the drone during ground parking and takeoff and landing, but it generates significant drag during flight. Retractable landing gear, on the other hand, can be retracted during flight, reducing drag and improving flight performance, but it is more complex and expensive. Landing gear materials are often high-strength, lightweight alloys or composite materials to balance strength and weight. Its design must also consider cushioning performance, using shock-absorbing devices to reduce landing impact, prevent fuselage damage, and ensure smooth takeoff and landing and safe operation of the drone.

[0003] Utility model patent CN208731210U discloses a foldable drone landing gear and its locking device, including a connecting rod, a fixed tube clamp, and landing feet connected sequentially to the drone arm. The connecting rod and the fixed tube clamp are hinged, and the connecting rod and the fixed tube clamp are locked or unlocked by the locking device. This utility model's foldable drone landing gear and its locking device allow the drone landing gear to be folded and locked by rotation, greatly reducing the space occupied by the drone and facilitating storage and transport.

[0004] However, if a mechanical failure occurs when the landing gear of this drone is locked during storage and the locking mechanism fails to engage, it is difficult for the user to detect, which can easily cause malfunctions during flight. Therefore, a mechanism for locking the landing gear of a drone is proposed to solve the problems mentioned above. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a mechanism for locking the landing gear of unmanned aerial vehicles (UAVs), which has advantages such as the ability to detect the locking mechanism and solves the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A mechanism for locking the landing gear of a drone includes a mounting chassis and a drone body. The bottom of the mounting chassis has two mounting slots, and a locking component is provided on the bottom of the mounting chassis.

[0008] The locking assembly includes a rotary knob rotatably mounted on the bottom of the mounting chassis, and two locking rods are fixedly mounted on the surface of the rotary knob. A locking sensor is fixedly mounted on the top of each locking rod.

[0009] Furthermore, the locking rod is a hollow rod, and a connecting wire is fixedly installed inside the locking rod. One end of the connecting wire is electrically connected to the locking sensor, and the other end of the connecting wire is electrically connected to the main body of the drone.

[0010] Furthermore, the mounting chassis has an internal mounting cavity, and a rotating motor is fixedly mounted at the bottom of the mounting cavity. The output shaft of the rotating motor is fixedly connected to the top of the rotating knob.

[0011] Furthermore, a ventilation and heat dissipation hole is provided on one side of the mounting groove, and the ventilation and heat dissipation hole is connected to the mounting cavity.

[0012] Furthermore, two mounting arms are fixedly installed on both sides of the mounting chassis, and mounting side plates are fixedly installed at the bottom of the mounting arms. A rotating shaft is rotatably installed between the two mounting side plates.

[0013] Furthermore, a landing gear is fixedly mounted on the surface of the rotating shaft, a storage sensor is fixedly mounted on the top of the mounting slot, a storage motor is fixedly mounted on one side of the mounting side plate, and the output shaft of the storage motor is fixedly connected to one end of the rotating shaft.

[0014] Furthermore, a flight shaft is rotatably mounted on the top of the mounting arm, a propeller is fixedly mounted on the top of the flight shaft, and a high-speed motor is fixedly mounted on the bottom of the mounting arm, with the output shaft of the high-speed motor fixedly connected to the bottom end of the flight shaft.

[0015] Furthermore, the main body of the drone is fixedly mounted on the top of the mounting chassis, and the bottom of the mounting chassis has two limiting grooves that are adapted to the locking sensor.

[0016] Compared with the prior art, this utility model provides a mechanism for locking the landing gear of a drone, which has the following advantages:

[0017] This mechanism for locking the landing gear of drones uses a rotating knob at the bottom of the mounting chassis. A locking lever is located on the surface of the rotating knob. After the landing gear is retracted into the mounting slot, the locking lever rotates to the bottom of the landing gear, locking the sensor into contact with the landing gear and transmitting a signal of successful locking to the drone body. This solves the common problem of drone landing gear malfunctions during retraction and locking, where the locking mechanism fails to engage and is difficult for the user to detect, potentially causing malfunctions during flight.

[0023] 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.

[0024] Please see Figures 1 to 4 The mechanism for locking the landing gear of a drone in this embodiment includes a mounting chassis 1 and a drone body 19. The bottom of the mounting chassis 1 has two mounting slots 2 and a locking component is provided at the bottom of the mounting chassis 1.

[0025] The locking assembly includes a rotary knob 3 rotatably mounted on the bottom of the mounting chassis 1, two locking rods 4 fixedly mounted on the surface of the rotary knob 3, and a locking sensor 5 fixedly mounted on the top of the locking rods 4.

[0026] Specifically, rotating knob 3 rotates the two locking levers 4, which in turn rotate the locking sensor 5 to detect the locking status and prevent mechanical failures that could cause knob 3 to rotate incorrectly, thus avoiding problems that the user might not be able to detect when locking fails.

[0027] Please see Figure 1 and Figure 2 In this embodiment, the locking rod 4 is a hollow rod, and a connecting wire 6 is fixedly installed inside the locking rod 4. One end of the connecting wire 6 is electrically connected to the locking sensor 5, and the other end of the connecting wire 6 is electrically connected to the drone body 19.

[0028] It should be noted that the main body 19 of the drone is a common drone control structure, which contains power supply, controller and sensors.

[0029] The mounting chassis 1 has an internal mounting cavity 7, and a rotating motor 8 is fixedly mounted at the bottom of the mounting cavity 7. The output shaft of the rotating motor 8 is fixedly connected to the top of the rotating knob 3.

[0030] Secondly, a ventilation hole 9 is provided on one side of the mounting groove 2, and the ventilation hole 9 is connected to the mounting cavity 7. The rotating motor 8 drives the rotating knob 3 to rotate, which in turn drives the locking rod 4 to rotate.

[0031] Please see Figures 1 to 3 In this embodiment, two mounting arms 10 are fixedly installed on both sides of the mounting base 1, and mounting side plates 11 are fixedly installed at the bottom of the mounting arms 10. A rotating shaft 12 is rotatably installed between the two mounting side plates 11.

[0032] The landing gear 13 is fixedly mounted on the surface of the rotating shaft 12, the storage sensor 14 is fixedly mounted on the top of the mounting groove 2, the storage motor 15 is fixedly mounted on one side of the mounting side plate 11, and the output shaft of the storage motor 15 is fixedly connected to one end of the rotating shaft 12.

[0033] Specifically, during takeoff, the retraction motor 15 drives the rotating shaft 12 to rotate, which in turn drives the landing gear 13 to rotate, rotating the landing gear 13 into the mounting slot 2 and into contact with the retraction sensor 14. The retraction sensor 14 transmits a signal that the landing gear 13 is retracted to the main body of the drone 19. The main body of the drone 19 controls the rotating motor 8 to drive the rotating knob 3 to rotate, which drives the locking lever 4 to rotate to the bottom of the landing gear 13, locking the landing gear 13. The locking sensor 5 contacts the landing gear 13 and transmits a signal that the locking is complete to the main body of the drone 19.

[0034] Secondly, a flight shaft 16 is rotatably mounted on the top of the mounting arm 10, a propeller 17 is fixedly mounted on the top of the flight shaft 16, and a high-speed motor 18 is fixedly mounted on the bottom of the mounting arm 10. The output shaft of the high-speed motor 18 is fixedly connected to the bottom end of the flight shaft 16.

[0035] Meanwhile, the main body 19 of the drone is fixedly installed on the top of the mounting chassis 1. The bottom of the mounting chassis 1 has two limiting grooves 20, which are adapted to the locking sensor 5.

[0036] It should be noted that both the storage sensor 14 and the locking sensor 5 are pressure sensors, which transmit signals to the main body of the drone 19 when subjected to pressure from the landing gear 13.

[0037] The working principle of the above embodiment is as follows: During takeoff, the retraction motor 15 drives the rotating shaft 12 to rotate, which in turn drives the landing gear 13 to rotate, rotating the landing gear 13 into the mounting slot 2 and into contact with the retraction sensor 14. The retraction sensor 14 transmits the signal that the landing gear 13 is retracted to the main body of the drone 19. The main body of the drone 19 controls the rotating motor 8 to drive the rotating knob 3 to rotate, which drives the locking lever 4 to rotate to the bottom of the landing gear 13, locking the landing gear 13. The locking sensor 5 contacts the landing gear 13 and transmits the signal that the locking is complete to the main body of the drone 19.
