Description

Transport drone with buffer landing gear

Technical field:

The invention relates to a transport drone with a buffer landing gear.

Background technique:

After the drone completes its mission, it needs to land. Existing drones will produce strong vibrations due to inertia when they land. This will cause damage to the drone parts or parts loose and fall off for a long time. Therefore, it is indeed necessary to improve the existing technology to solve the shortcomings of the existing technology.

Summary of the invention:

The present invention provides a transport drone with a cushioning landing gear in order to solve the above-mentioned problems in the prior art.

The technical solutions adopted by the present invention are:

A transport drone with a buffer landing gear, the drone body with a frame, and further includes a transport rack and a landing gear. The transport rack includes a bottom plate, a strap and a buckle with a male buckle and a female buckle. The strapping strap is fixedly connected to the frame, the male buckle and the female buckle in the buckle are respectively fixedly connected to both ends of the strapping strap, and an installation slot is provided on the bottom plate, the strapping strap passes through the installation slot, and the strapping The male buckle and the female buckle are connected to each other;

The landing gear includes a landing arm, a torsion spring, and a roller. Two mounting rods are provided on the frame, and each mounting rod is provided with a landing arm and a torsion spring. One end of the torsion spring abuts on the mounting rod, and the other One end abuts on the landing arm, and the roller is rotatably connected to the bottom end of the landing arm.

Further, the top end of the landing arm is provided with a mounting hole, and the landing arm is sleeved on the mounting rod through the mounting hole.

Further, the landing arm is made of aluminum, and a weight reduction hole is provided on the landing arm.

Further, the bottom plate is made of rubber material.

Further, the straps are fixedly connected to the frame by screws.

Further, there are four landing arms, which are respectively arranged at the four corners of the frame.

The present invention has the following beneficial effects:

The structure design of the invention is reasonable, the buffer effect is good, the material transportation is convenient, and the use effect is good.

Description of the drawings:

Figure 1 is a structural diagram of the present invention.

Figure 2 is a structural diagram of the present invention.

Figure 3 is a structural diagram of the landing gear in the present invention.

Detailed ways:

The present invention will be further described below in conjunction with the accompanying drawings.

As shown in Figures 1 to 3, the present invention is a transport drone with a buffer landing gear, a transport frame 2, a landing gear 3, and a drone body with a frame 1.

The transport rack 2 includes a bottom plate 21, a strap 22, and a buckle 23 with male and female buckles. The strap 22 is fixedly connected to the frame 1, and the male and female buckles in the buckle 23 are respectively fixedly connected to the strap 22. The bottom plate 21 is provided with installation grooves on both ends of the tying belt, the strap 22 passes through the installation groove, and the male buckle and the female buckle on the strap 22 are inserted into each other.

The bottom plate 21 and the strap 22 are connected by a buckle 23. When the material is fixed, the material is placed on the bottom plate, and then the position of the strap is adjusted to move the bottom plate up so that the material is fixed between the bottom plate and the frame.

The landing gear 3 in the present invention includes a landing arm 31, a torsion spring 32 and a roller 33. Two mounting rods are provided on the frame 1, and each mounting rod is provided with a landing arm 31 and a torsion spring 32. The torsion spring One end of 32 abuts on the mounting rod, the other end abuts on the landing arm 31, and the roller 33 is rotatably connected to the bottom end of the landing arm 31.

When the drone is falling, the gravity of the drone acts on the landing gear 3, so that the landing arm 31 is stretched outward, and the torsion spring 32 is twisted at this time. The landing gear 3 is stretched outwards to play a buffering role, and the torsion spring is reset when the UAV takes off.

In order to facilitate the installation of the landing arm 31 on the mounting rod, a mounting hole 30 is provided at the top of the landing arm 31, and the landing arm 31 is sleeved on the mounting rod through the mounting hole 30.

The landing arm 31 of the present invention is made of aluminum, and the landing arm 31 is provided with a weight reduction hole.

The bottom plate 21 is made of rubber material, and the rubber plate can avoid scratching the transported materials.

The strap 22 in the present invention is fixedly connected to the frame by screws.

There are four landing arms 31, which are respectively arranged at the four corners of the frame.

The above are only the preferred embodiments of the present invention. It should be pointed out that for those of ordinary skill in the art, several improvements can be made without departing from the principle of the present invention, and these improvements should also be regarded as the present invention. protected range.
