Description

Technical Field

[0001] This utility model relates to a landing gear buffer and shock absorption structure for transport drones, belonging to the field of drone technology. Background Technology

[0002] Drones, as the name suggests, are unmanned aircraft. Since the birth of airplanes in the early 20th century, people have proposed the idea of ​​unmanned aircraft due to safety concerns about piloting airplanes. Until the 1930s, with the development of drone technology, more and more drones were applied to various aspects of people's lives.

[0003] When a drone lands, the landing gear comes into contact with the landing point, causing severe vibrations. These severe vibrations can easily loosen internal parts of the drone. Therefore, some drones use landing gear with shock-absorbing structures to reduce vibrations during landing.

[0004] Installing shock-absorbing structures on the landing gear increases the number of parts on the drone, thereby increasing the overall weight of the drone and affecting its stability, maneuverability, and flight capability. At the same time, there are many drones on the market that do not use shock-absorbing landing gear. These drones are already assembled, and replacing the landing gear is not only time-consuming but also increases the production cost of the drone. Utility Model Content

[0005] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a landing gear buffer and shock absorption structure for transport drones, so as to solve the problem mentioned in the background art that installing a shock absorption structure on the landing gear will increase the number of parts on the drone, thereby increasing the overall weight of the drone, and thus affecting the stability, maneuverability and flight capability of the drone during flight.

[0006] To achieve the above objectives, this utility model is implemented through the following technical solution: a landing gear buffer and shock absorption structure for a transport drone, including a parking platform, wherein working slots are correspondingly provided on both sides of the parking platform;

Both ends of the outer side of the two guide rods are fitted with displacement sliders, and the bottom of each displacement slider is hinged with a movable rod. The ends of the movable rods away from the displacement sliders are respectively hinged to the four corners of the top of the mounting plate.

[0011] Furthermore, assembly plates are installed at both ends of the top of the mounting base plate, and mounting sleeves are arranged in an array on the top of the assembly plates. Assembly plates are installed on both sides of the bottom of the parking platform, and linkage columns are arranged in an array at the bottom of the assembly plates.

Shock absorbers are installed between the top of the cavity of the mounting sleeve and the bottom of the linkage column. Shock-absorbing springs are fitted on the outside of each linkage column. Buffer springs are fitted on the middle of the outside of each of the two guide rods, and auxiliary springs are fitted on both ends of the outside of each of the two guide rods.

[0012] Furthermore, a stabilizing base is placed below each of the two mounting plates. Each of the two stabilizing bases has a lower adjusting post at both ends of its top. Each of the lower adjusting posts has an adjusting screw opening at its top, and the lower adjusting posts correspond one-to-one with the upper adjusting posts. A bidirectional screw is placed between the lower and upper adjusting posts. The upper part of the bidirectional screw passes through the adjusting screw opening of the upper adjusting post and is located inside the upper adjusting post cavity, while the lower part of the bidirectional screw passes through the adjusting screw opening of the lower adjusting post and is located inside the lower adjusting post cavity.

[0016] 2. The parking mechanism and the drone are designed separately, which will not affect the operation of the drone and avoid increasing the weight of the drone, thereby reducing the stability, maneuverability and flight capability of the drone during flight.

[0017] 3. The landing mechanism utilizes an extended platform to change the area of ​​the drone's landing point, allowing the landing mechanism to adapt to drones of various sizes and enhancing the device's practicality.

[0018] 4. The fixed mechanism can stabilize the position of the device and prevent the impact force when the drone lands from knocking it over. At the same time, the two stable bases supporting the device can be adjusted in height, so that the device can better adapt to complex outdoor environments. Attached Figure Description

This expands the landing point area formed by the extension platform 3 and the landing platform 1. The user adjusts the landing point area according to the size of the drone. When the landing point receives the drone, the buffer spring 25, shock absorber 23, and shock-absorbing spring 24 work together to eliminate amplitude and improve shock absorption. Simultaneously, when the drone flies away from the landing point, the auxiliary spring 26 is used to... The buffer spring 25, shock absorber 23 and shock absorber spring 24 buffer the force when they return to their original state, so as to avoid excessive force when they return to their original state, which would cause vibration at the landing point and affect the take-off of the UAV. When the device is installed, the height of the two stable bases 27 can be adjusted by rotating the bidirectional screw 29, so that the two stable bases 27 can adapt to uneven ground. Then, the adjusting stud 32 is rotated to move the adjusting stud 32 with the fixing nail 34 of the moving plate 33 downward, and the fixing nail 34 is embedded in the position of the ground fixing device.
