When an accidental impact occurs, the anti-collision block (30) undergoes preferential deformation, and the air inside the block is squeezed out for primary impact force buffering and absorbing, after which the press rod (3) receives a force to push the press plate (21) to move, and the buffer piece (20) is pressed for secondary impact force buffering and absorbing, thereby significantly reducing impact damage, and protecting an unmanned aerial vehicle. The whole structure is simple and costs are low.

Description

 Unmanned aerial vehicle anti-collision structure Technical field

The invention relates to the technical field of drones, and more particularly to an anti-collision structure of a drone body.

Background technique

UAVs are unmanned aircraft operated by radio remote control equipment and self-provided program control devices. Civil drones have important applications in aerial photography, agriculture, plant protection, disaster relief, etc.; currently used UAV fuselage shells Most of the body is not equipped with anti-collision structure or the anti-collision structure is unreasonable, and it is impossible to effectively reduce and absorb the impact in the event of an accidental collision.

technical problem

The technical problem to be solved by the present invention is to provide a UAV body collision avoidance structure capable of effectively reducing and absorbing an impact against the above-mentioned drawbacks of the prior art.

Technical solution

The technical solution adopted by the present invention to solve the technical problem thereof is:

Constructing a UAV body collision avoidance structure, comprising a casing; wherein a casing of the casing is fixedly disposed with a buffer box; and a sidewall of the casing is provided with a through hole communicating with the buffer box; The buffer box is provided with a buffering member and a pressure plate; and further comprises a pressing rod penetrating through the through hole, the one end of the pressing rod is fixedly connected with the pressing plate, and the other end is connected with a hemispherical elastic anti-collision block, the anti-collision block The interior is hollow and the surface is provided with a plurality of air holes.

The anti-collision structure of the unmanned aerial vehicle body of the present invention, wherein the buffering member is an elastic water bag; and the plastic plate is connected to the upper plate portion.

The unmanned aerial vehicle anti-collision structure of the present invention further includes a spring piece connecting the plastic baffle and the pressure plate.

In the unmanned aerial vehicle anti-collision structure of the present invention, a spring is further disposed inside the anti-collision block.

Beneficial effect

The beneficial effects of the invention are: when an accidental impact occurs, the anti-collision block is preferentially deformed, the internal gas is extruded, and an impact force is buffered and absorbed, and the rear pressing rod is forced to push the pressing plate to press, and the buffering member is pressed. The secondary impact force buffering and absorbing greatly reduces the impact damage, thereby protecting the drone; the overall structure is simple and the cost is low.

DRAWINGS

In order to more clearly illustrate the embodiments of the present invention or the prior art, the present invention will be further described in conjunction with the accompanying drawings and embodiments. For ordinary technicians, other drawings can be obtained based on these drawings without any creative work:

1 is a schematic view showing the structure of an anti-collision structure of a UAV body according to a preferred embodiment of the present invention.

Embodiments of the invention

The present invention will be described in detail with reference to the embodiments of the present invention. Not all embodiments. All other embodiments obtained by a person of ordinary skill in the art based on the embodiments of the present invention without any inventive effort are within the scope of the present invention.

As shown in FIG. 1 , the unmanned aerial vehicle anti-collision structure of the preferred embodiment of the present invention includes an unmanned aerial vehicle anti-collision structure, including a casing 1 , and a buffer box 2 is fixedly disposed on an inner side wall of the casing 1 . The side wall of the casing 1 is provided with a through hole 10 communicating with the buffer box 2; the buffer box 2 is provided with a buffering member 20 and a pressure plate 21; and further comprises a pressing rod 3 penetrating through the through hole 10, and one end of the pressing rod 3 is fixed to the pressing plate 21 The other end is connected with a hemispherical elastic anti-collision block 30. The anti-collision block 30 is hollow inside and has a plurality of air holes (not shown) on the surface; when an accidental impact occurs, the anti-collision block 30 preferentially deforms, and the inside thereof The gas is squeezed out, and an impact force is buffered and absorbed, and then the pressure bar 3 is forced to move the pressure plate 21, and the buffer member 20 is squeezed to buffer and absorb the secondary impact force, thereby greatly reducing the impact damage, thereby protecting the unmanned person. Machine; the overall structure is simple and the cost is low.

As shown in FIG. 1 , the cushioning member 20 is an elastic water bag; the upper portion of the pressing plate 21 is connected with a plastic blocking piece 210; when striking, the pressing plate 21 presses the water bag 20, and the water bag is deformed to push the plastic blocking piece 210 to increase the impact on the impact. The degree of absorption of the force effectively reduces the vibration interference of the internal parts of the drone.

As shown in FIG. 1, the elastic piece 211 connecting the plastic baffle 210 and the pressing plate 21 is further included to enhance the strength against momentary impact.

As shown in FIG. 1, the anti-collision block 30 is further provided with a spring 300 to enhance the buffer deformation strength of the anti-collision block 30.

It is to be understood that those skilled in the art will be able to make modifications and changes in accordance with the above description, and all such modifications and variations are intended to be included within the scope of the appended claims.
