Detailed Description

The principles and features of the present invention are described below in conjunction with the following drawings, the examples given are only intended to illustrate the present invention and are not intended to limit the scope of the present invention.

As shown in fig. 1, the bidirectional buffering undercarriage comprises a front buffering plate 1 and a rear buffering plate 3, wherein the front buffering plate 1 and the rear buffering plate 3 are connected through a connecting strip 2, and the front buffering plate and the rear buffering plate are respectively and fixedly connected with two end parts of a main undercarriage 6 through a front buffering plate connecting bolt 7 and a rear buffering plate connecting bolt 8; the connecting strip 2 is positioned under the main landing gear 6, and a sliding groove 9 for the relative movement of the front buffer plate 1, the rear buffer plate 3 and the connecting strip 2 is arranged on the connecting strip 2;

when the landing gear is specifically implemented, the front buffer plate and the rear buffer plate are connected with the landing gear main body through the front buffer plate connecting bolts and the rear buffer plate are connected through the connecting bolts, and small-amplitude movement can be performed through the sliding grooves.

More specifically, the main landing gear 6 is a bidirectional inclined structure, and two side plates of the main landing gear are inclined outwards by a certain angle;

more specifically, the front buffer plate 1 and the rear buffer plate 3 are respectively sleeved with a front buffer sponge 4 and a rear buffer sponge 5;

the landing gear of the utility model comprises three parts, including a main landing gear, a front buffer plate and a rear buffer plate, for the convenience of description, the current definition is X axis along the direction of the buffer plate, the direction perpendicular to the buffer plate and parallel to the ground is Y axis, and the direction perpendicular to the ground is Z axis; the main landing gear forms an angle with an XZ plane and forms an angle with a YZ plane; when the aircraft lands, the landing gear can elastically deform in X, Y two directions simultaneously, so that the two-way deformation can absorb impact energy under the minimum deformation. The buffer board is used for increasing area of contact, improves descending stability, and the buffer board divide into preceding, back buffer board again, and the two relies on a movable sliding tray to connect to guarantee that main undercarriage can carry out limited deformation motion on the X axle.

More specifically, an included angle between a top plate of the main landing gear 6 and side plates on two sides is 45 degrees;

more specifically, the included angle between the side plates on the two sides and the front buffer plate and the rear buffer plate is 17 degrees;

the utility model has the advantages of as follows: when the unmanned aerial vehicle that hangs down descends, after the undercarriage contacted ground, because carbon fiber material has certain toughness, the undercarriage main part can be followed Y axle direction deformation to along X axle direction deformation simultaneously, through the impact energy when descending of the common effect absorption of two directions. Under the same impact, the unidirectional deformation easily exceeds the allowable value of the carbon fiber, the landing gear is easily damaged, the impact is absorbed in the two directions at the same time, and the deformation in each direction is not easily beyond the allowable value, so that the use limit of the landing gear is improved.

The above description is only for the preferred embodiment of the present invention, and is not intended to limit the present invention, and any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention should be included within the protection scope of the present invention.
