Technical Field

[0001] The utility model belongs to the technical field of unmanned aerial vehicles, and particularly relates to an undercarriage of an unmanned aerial vehicle. Background Art

[0002] An unmanned aerial vehicle is an aircraft that does not require a pilot to board for any manual driving operation and can automatically complete the entire flight process completely under the monitoring of electronic devices. Its appearance has brought the research on aircraft in various countries into a brand-new era. Unmanned aerial vehicles have strong survivability, high flexibility, good maneuverability, and are very convenient to use. Micro-rotor unmanned aerial vehicles are the products of the integration of micro-electro-mechanical systems, and have become the focus of research in many laboratories at home and abroad due to their advantages such as being able to take off and land vertically, hover freely, be flexibly controlled, and have strong adaptability to various environments.

[0003] The patent document with the publication number "CN115610643B" records "an anti-vibration undercarriage for an unmanned aerial vehicle. A buffer leg is rotatably connected below a fixed frame, a mounting box is fixedly connected to the middle of the lower part of the fixed frame, an anti-vibration mechanism is movably connected inside the mounting box, the top of the anti-vibration mechanism penetrates through the fixed frame and is fixedly connected to a connecting plate, and an installation plate is elastically connected above the connecting plate; the anti-vibration mechanism includes a pressing component and a deceleration component. When the unmanned aerial vehicle lands, the downward movement speed of the connecting plate will be slowed down. Due to the reduction of the downward pressure of the unmanned aerial vehicle, the push rod will no longer push the spiral rotating plate to rotate, realizing the landing of the unmanned aerial vehicle; and at this time, the ejector rod on the limit rack will extend into the circular groove to lock and limit the whole undercarriage. The cooperation of each structure of the undercarriage can achieve multi-stage buffering and improve the stability of the unmanned aerial vehicle body during landing".

[0029] Embodiment 1

[0030] Please refer to Figures 1-4 , the present utility model provides the following technical solutions:

[0031] An unmanned aerial vehicle landing gear, comprising:

[0032] an upper plate 1 and a lower plate 2;

[0033] two connecting rods 6, the two connecting rods 6 are respectively fixedly connected to the closer ends of the upper plate 1 and the lower plate 2;

[0034] a spool 9, the spool 9 is located inside the two connecting rods 6;

[0035] a telescopic rod 5, the telescopic rod 5 is fixedly connected to the upper end of the lower plate 2;

[0036] a hanging ring 11, the hanging ring 11 is fixedly connected to the extended end of the telescopic rod 5;

[0037] Fixing rod 10, the fixing rod 10 is fixedly connected to the lower end of the upper plate 1, and the hanging ring 11 is sleeved on the circumferential surface of the fixing rod 10.

[0038] In a specific embodiment of the present invention, there are four sets of two connecting rods 6, telescopic rods 5 and winding drums 9 in this device. The upper plate 1 is made of a light and high-strength material to ensure sufficient strength while reducing weight. The lower plate 2 is mainly responsible for contacting the ground and providing a stable foundation when the landing gear is in use. The two connecting rods 6 enhance the structural stability of the entire landing gear and also allow the landing gear to be folded or unfolded during use. The winding drum 9 is used for fixing the two connecting rods 6, enabling the upper plate 1 and the lower plate 2 to be connected, which can reduce the impact force when the drone lands. The telescopic rod 5 realizes the height adjustment of the landing gear. By setting different lengths of the telescopic rod 5, when the drone contacts the device, it can play a buffering effect. The cooperation of the hanging ring 11 and the fixing rod 10 enables the landing gear to maintain a stable state when the drone descends above the upper plate 1 and will not move unnecessarily due to factors such as air flow.

[0039] Specifically, please refer to Figures 1-4 The lower end of the lower plate 2 is fixedly connected with a base 3, and the material of the base 3 is rubber.

[0040] In this embodiment: The base 3 is made of rubber. The selection of the rubber material is to provide better friction and buffering effects, which helps to reduce the impact force of the drone on the ground when landing, and at the same time increases the grip ability of the landing gear to prevent the gravity device from tilting when the drone stops stably.

[0041] Specifically, please refer to Figures 1-4 One side end of the upper plate 1 is fixedly connected with two base support blocks 12, and the closer ends of the two base support blocks 12 are fixedly connected with a connecting rod 13.

[0042] In this embodiment: The base support blocks 12 can be used to support the four corners of the drone. When the drone stops stably, it can be used to protect the drone from tilting.

[0043] Specifically, please refer to Figures 1-4 Both sides ends of the upper plate 1 are fixedly connected with arc-shaped cushion plates 7.

[0044] In this embodiment: The arc-shaped cushion plates 7 provide an additional protective layer for the upper plate 1 to prevent damage to the upper plate 1 in a harsh environment. At the same time, the arc-shaped cushion plates 7 can also facilitate the use of various drones.

[0045] Specifically, please refer to Figures 1-4 The circumferential surfaces of the two arc-shaped cushion plates 7 are fixedly connected with arc-shaped protective plates 8, and the arc-shaped protective plates 8 are made of stainless steel.

[0046] In this embodiment, if the drone tilts before it comes to a complete stop, the arc-shaped protective plate 8 can prevent the drone from falling and keep it from contacting the ground, providing safety.

[0047] Specifically, please refer to Figures 1-4 , a threaded hole 14 is formed at the upper end of the lower plate 2. A bolt 4 is threadedly connected to the threaded hole 14. The lower end of the bolt 4 is fixedly connected to a tapered head, and the bolt 4 passes through the base 3.

[0048] In this embodiment, when used on sandy or uneven ground, the bolt 4 is threadedly connected to the threaded hole 14. In this way, the tapered head at the bottom of the bolt 4 will penetrate through the base 3 and gradually contact the uneven ground, enabling the device to maintain a stable state in different environments and being applicable to multiple environments.

[0049] The working principle and usage process of the present utility model: When the drone lands in a complex environment, the bottom of the drone first contacts the upper plate 1. Since the gravity telescopic rod 5 will be in a contracted state, and at the same time the connecting rod 6 will gradually be in a crossed state, the upper plate 1 will move downward. By slowly contracting the telescopic rod 5, the impact force caused by the drone's landing can be reduced. When the drone lands above the upper plate 1, with the telescopic rod 5 expanding and contracting, the landing gear can maintain a stable state and will not move unnecessarily due to factors such as air flow.

[0050] Finally, it should be noted that the above are only the preferred embodiments of the present utility model and are not used to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
