Description

Technical Field

[0001] This utility model relates to the field of drones, and in particular to a detachable drone landing gear. Background Technology

[0002] The landing gear is an important component of a drone. It is used to support the drone's take-off and landing operations and to protect the drone's bottom structure from damage.

[0003] Most existing drone landing gear is round rod-shaped, which makes it easy to install a basket, and the round rod structure has high support strength at high temperatures. However, the support area of ​​existing drone landing gear is small, which makes it easy for drones to get stuck in the mud when landing on special landing pads such as mud due to their own weight and the impact of unloading.

[0004] Therefore, a detachable drone landing gear has been developed that can increase the support area of ​​the support feet and prevent the support feet from sinking into the mud when the drone lands on muddy ground. Utility Model Content

[0005] To overcome the shortcomings of existing drone landing gear, which has a small support area and is prone to sinking into mud or other special landing pads due to its own weight and the impact of material unloading, this utility model provides a detachable drone landing gear that can increase the support area of ​​the support feet and prevent the drone from sinking into the mud when landing.

[0006] The technical implementation scheme of this utility model is as follows: a detachable drone landing gear, including a support foot, a connecting frame, a slider, a nut and an anti-sinking mechanism. There are two support feet. The upper sides of the front and rear parts of the support feet are connected to the connecting frame. The left and right parts of the connecting frame are slidably connected to the slider. The slider is connected to the nut. The support feet are equipped with an anti-sinking mechanism to prevent the drone from sinking into the mud.

[0007] Optionally, the anti-sinking mechanism includes an extension plate, a pin, and an elastic element. The lower part of each support foot is rotatably connected to an extension plate, and the front and rear parts of the extension plate are slidably connected to pins. Each pin is connected to an elastic element between it and the adjacent extension plate. When the extension plate rotates on the support foot and forms a 90-degree angle with the support foot, it can increase the support area of ​​the support foot and prevent the support foot from sinking into the mud.

[0008] Optionally, it also includes a buffer mechanism, which includes an air pump and an airbag. An air pump is connected to the top of each extension plate, and an airbag is connected to the bottom of each extension plate. Each airbag is connected to an adjacent air pump. The air pump injects air into the airbag, causing the airbag to expand and buffer the impact force when the support foot falls.

[0009] Optionally, the lower sides of both the front and rear parts of the support leg have insertion holes, and the pins are engaged with the adjacent insertion holes.

[0010] Optionally, each pin is equipped with a pull block to facilitate pulling out the pin.

[0011] Optionally, the elastic element is a spring.

[0012] Beneficial effects: 1. This utility model increases the support area of ​​the support foot by rotating the extension plate on the support foot. When the extension plate makes a 90-degree angle with the support foot, it can prevent the support foot from sinking into the mud when the drone lands on muddy ground.

[0013] 2. This utility model uses an air pump to inject air into the airbag, causing the airbag to expand and thus cushioning the impact force when the supporting foot lands. Attached Figure Description

[0019] To make the objectives, technical solutions, and advantages of this utility model clearer, the following will describe this utility model in further detail with reference to the accompanying drawings. It is hereby declared that the terms "up," "down," "left," "right," "front," "back," "inner," and "outer," etc., appearing or about to appear in this document, are based solely on the accompanying drawings and are not intended to specifically limit this utility model.

[0020] A detachable drone landing gear, such as Figure 1 and Figure 2 As shown, it includes a support foot 1, a connecting frame 2, a slider 3, a nut 4, and an anti-sinking mechanism 5. There are two support feet 1. The lower sides of the front and rear parts of the support foot 1 have insertion holes 101. The upper sides of the front and rear parts of the support foot 1 are connected to the connecting frame 2. The left and right parts of the connecting frame 2 are slidably connected to the slider 3. The slider 3 is connected to the nut 4. The support foot 1 is equipped with an anti-sinking mechanism 5.

[0021] like Figure 1 and Figure 3 As shown, the anti-sinking mechanism 5 includes an extension plate 50, a pin 51, and a spring 52. The lower part of the support leg 1 is rotatably connected to the extension plate 50. The front and rear parts of the extension plate 50 are slidably connected to the pin 51. Each pin 51 is provided with a pull block to facilitate pulling out the pin 51. Each pin 51 is connected to the adjacent extension plate 50 by a spring 52. Each pin 51 is engaged with the adjacent socket 101.

[0022] In use, the position of the nut 4 is first adjusted by the slider 3 to fit the size of the drone. Then, the slider 3 is installed on the drone by the nut 4, so that the drone can move the connecting frame 2 and the support foot 1 when taking off. When the drone needs to land on muddy ground, before the drone takes off, the pin 51 is pulled out and the extension plate 50 is rotated so that the extension plate 50 and the support foot 1 form a 90-degree angle, which can increase the support area of ​​the support foot 1 and prevent the support foot 1 from sinking into the mud when the drone lands. When landing on normal road sections, the extension plate 50 can be rotated to fit the support foot 1, and the support foot 1 can be used for take-off and landing support to save space.

[0023] like Figure 1 and Figure 4 As shown, it also includes a buffer mechanism 6, which includes an air pump 60 and an airbag 61. The top of the expansion plate 50 is connected to the air pump 60, and the bottom of the expansion plate 50 is connected to the airbag 61. The airbag 61 is connected to the adjacent air pump 60.

[0024] Using the buffer mechanism 6 of this utility model, impact buffering can be performed when the drone is descending. When the drone is descending, the air pump 60 is activated to inject air into the airbag 61, causing the airbag 61 to expand and buffer the impact force when the support foot 1 falls.

[0025] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made using the content of this utility model specification, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
