In order to solve the technical problem, the utility model discloses a technical scheme does:

a shock-absorbing structure of engine in unmanned aerial vehicle includes: the shock absorption device comprises a fixed base plate used for mounting an engine, a baffle used for fixing shock absorption balls, a suspension column with internal threads and arranged on one side of the fixed base plate, a plurality of shock absorption balls arranged between the fixed base plate and the baffle, and a nut gasket arranged between the suspension column and the fixed base plate, wherein the suspension column is connected with the baffle through a screw.

Furthermore, the nut gasket is matched with the screw rod to enable the damping ball to be in a compression state all the time.

Furthermore, the edge of the fixed bottom plate is provided with mounting holes matched with the damping balls in a clamping manner, and at least two mounting holes are arranged on two sides of the screw rod.

Further, the number of the mounting holes is four, the mounting holes are arranged at four vertexes of the rectangle, and the screw is located at the center of the rectangle.

Furthermore, a spring is arranged between the baffle plate and the fixed bottom plate.

Furthermore, a spring limiting hole is formed in the fixed base plate, a gasket is arranged in the spring limiting hole, and the screw penetrates through the spring and the gasket to be connected with the suspension column.

Compared with the prior art, the utility model provides a pair of shock-absorbing structure of engine among unmanned aerial vehicle, PMKD is used for connecting the engine, and on the baffle was fixed in unmanned aerial vehicle's undercarriage, adjusted damping ball through the nut gasket by the extrusion degree and then realize that extrusion damping ball prevents droing of damping ball.

Detailed Description

The following describes the present invention with reference to the accompanying drawings. It should be noted that the description of the embodiments is provided to help understanding of the present invention, but the present invention is not limited thereto. In addition, the technical features related to the embodiments of the present invention described below may be combined with each other as long as they do not conflict with each other.

Example (b):

as shown in fig. 1-2, a shock-absorbing structure of engine in unmanned aerial vehicle includes: the shock absorption device comprises a fixed base plate 1 for mounting an engine and a baffle plate 2 for fixing shock absorption balls 5, wherein a suspension column 3 with internal threads is arranged on one side of the fixed base plate 1, a plurality of shock absorption balls 5 are arranged between the fixed base plate 1 and the baffle plate 2, the suspension column 3 is connected with the baffle plate 2 through a screw 6, and the shock absorption device further comprises a nut gasket 4, and the nut gasket 4 is arranged between the suspension column 3 and the fixed base plate 1.

Wherein, the edge of the fixed bottom plate 1 is provided with a mounting hole 7 which is matched with the damping ball 5 in a clamping way; a spring 10 is arranged between the baffle plate 2 and the fixed bottom plate 1. The engine is mounted at the engine mount area 9.

In the thread part of one screw 6, when the suspension column 3 and the nut washer 4 rotate in the same direction, the two advance and retreat together; when the two are rotated in opposite directions, they are relatively close to each other or far away from each other. Therefore, the degree that the shock attenuation ball is compressed is can be regulated and control to can realize the level correction of PMKD and hang the fine setting of post height, this is crucial in unmanned aerial vehicle's balance adjustment.

In the process of flying, taking off or landing of the unmanned aerial vehicle, when the vibration of an engine is severe, the damping ball 5 between the fixed bottom plate 1 and the baffle 2 may collapse and fall off. Based on the structure, the distance between the adjusting nut gasket 4 and the bottom screw 6 is reduced, so that the damping ball 5 is always in a compression state. The method is one of the technical means for solving the problem that the damping ball 5 falls off in the unmanned aerial vehicle.

As a modification of the above embodiment, at least two of the mounting holes 7 are disposed on both sides of the screw 6, so that the damping balls on both sides receive substantially the same degree of compression, thereby preventing the damping balls from falling off.

Furthermore, the number of the mounting holes 7 is four, the mounting holes 7 are arranged at four vertices of a rectangle, and the screw 6 is located at the center of the rectangle. The degree of compression of the damping ball 5 is more consistent.

As another improvement of the above embodiment, a spring limiting hole is formed in the fixing bottom plate, a gasket is arranged in the spring limiting hole, and the screw 6 penetrates through the spring 10 and the gasket to be connected with the suspension column 3. The spring 10 enhances the damping effect and provides a strong elastic restoring force, so that the life of the damping ball 5 is prolonged. The gasket, the spring 10 and the screw 6 are concentrically matched, so that the spring 10 is in a stable working state.

The embodiments of the present invention have been described in detail with reference to the accompanying drawings, but the present invention is not limited to the described embodiments. It will be apparent to those skilled in the art that various changes, modifications, substitutions and alterations can be made in the embodiments without departing from the principles and spirit of the invention, and the scope of the invention is to be accorded the full scope of the claims.
