Abstract

A buffer mechanism for an unmanned aerial vehicle, comprising two stands (1) and a panel (2) for mounting the unmanned aerial vehicle, the panel (2) being provided thereon with holders (20) for holding the stands (1); a hollow cavity (21) is provided inside the panel (2), and the hollow cavity (21) is provided therein with a buffer board (210) and two dampening pads (211) sandwiching the buffer board therebetween; an end of each of the holders (20) is fixed onto the buffer board (210); the panel (2) is provided thereon with through-holes (22) fitting with the holders (20). When the unmanned aerial vehicle takes off and lands, the shock received by the stands (1) is transferred to the buffer board (210) via the holders (20), and the shock is absorbed by means of the dampening pads (211) on the upper and lower surfaces of the buffer board (210), efficiently preventing a shock effect, such that the vehicle body is protected. The buffer mechanism has a simple overall structure and is low in cost.

Description

UAV buffer mechanism

Technical field

The present invention relates to the field of drone technology, and more particularly to a drone buffer mechanism.

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.; drones need to take off and land. The shock absorber is used to protect the fuselage. The structure of the shock absorbing cushion mechanism currently used is complicated or unreasonable, and the shock absorbing effect is not satisfactory.

technical problem

The technical problem to be solved by the present invention is to provide a UAV buffer mechanism with good shock absorption and buffering effect 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 drone buffer mechanism, comprising two tripods and a panel for installing the drone; wherein the panel is provided with a clamping member for clamping the tripod; the panel is internally provided with a hollow a cavity, the buffer cavity is internally provided with a buffer plate and two cushions for clamping the buffer plate; the end of the clamp is fixedly disposed with the buffer plate; and the panel is provided with The through hole of the clamping member.

In the unmanned aerial vehicle buffer mechanism of the present invention, the buffer plate and the hollow cavity side wall are connected by a metal elastic rope.

In the UAV buffer mechanism of the present invention, the four corners of the lower surface of the baffle plate are connected to the hollow cavity through a spring.

In the unmanned aerial vehicle buffer mechanism of the present invention, the cushioning surface and the hollow cavity contact surface are provided with wave-shaped protrusions.

Beneficial effect

The utility model has the beneficial effects that when the drone is taken off and landed, the vibration of the tripod is transmitted to the buffer plate through the clamping member, and the vibration is absorbed by the two cushions on the lower surface of the buffer plate, thereby effectively preventing the vibration. The effect is to protect the fuselage; 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 a buffer mechanism of a drone 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.

The unmanned aerial vehicle buffer mechanism of the preferred embodiment of the present invention, as shown in FIG. 1, includes a UAV buffer mechanism, including two tripods 1 and a panel 2 for installing the drone, and the panel 2 is provided with a clip. The clamping member 20 of the supporting frame 1; the hollow portion 21 is disposed inside the panel 2, and the buffering plate 210 and the two cushioning pads 211 of the upper and lower clamping buffer plates 210 are disposed inside the hollow cavity 21; The portion is fixedly disposed with the buffer plate 210; the panel 2 is provided with a through hole 22 that cooperates with the clamping member 20; when the drone is taken off and landed, the vibration received by the stand 1 is transmitted to the buffer plate 210 through the clamping member 20, The vibration is absorbed by the two cushions 211 on the upper and lower surfaces of the buffer plate 210, thereby effectively preventing the vibration, thereby protecting the body; the overall structure is simple and the cost is low.

As shown in FIG. 1, the buffer plate 210 and the side wall of the hollow cavity 21 are connected by a metal elastic cord 212 to prevent displacement of the buffer plate 210, thereby ensuring the stability of the stand 1 and facilitating the transmission and absorption of vibration.

As shown in FIG. 1 , the four corners of the upper and lower surfaces of the buffer plate 210 are connected to the hollow cavity 21 through the spring 23, and the shock absorption effect is good and the balance is high.

As shown in FIG. 1, the contact surface of the cushion 211 and the hollow cavity 21 is provided with a wave-shaped protrusion 213 to prolong the buffering time and improve the cushioning and damping effect.

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.
