Description

Unmanned aerial vehicle wing body connection structure

Technical Field

The utility model belongs to the unmanned aerial vehicle field, concretely relates to unmanned aerial vehicle wing body connection structure.

Background

With the progress of mechanization, science and technology and informatization of the war, the moving speed and the concealment of ground targets on a modern battlefield are greatly improved, so that the shadows of the unmanned aerial vehicle are detected more and more frequently in the modern war. The soldiers on the front line of the battlefield need to perform long-time investigation on ground targets of enemies, so that the small-sized investigation unmanned aerial vehicle is created, in order to meet the requirements of convenience in carrying and long working time and have certain concealment, the unmanned aerial vehicle is generally in a normal pneumatic layout, has the appearance similar to that of a civil passenger plane, and has main components such as a machine body, wings, an empennage and the like which are disassembled and then placed in a backpack, and can be rapidly assembled and put into use after entering the battlefield. The wing and the fuselage of such unmanned aerial vehicles are usually assembled by means of screw connection, and screws are screwed into threaded holes in the fuselage by using a screwdriver, so that the wing and the fuselage are combined together, and 4-6 screws are generally required to be assembled. This type of mounting has the following disadvantages: the number of the screws is large, a large amount of time is spent on assembly, the assembly efficiency is low, enemy conditions on a battlefield change all the time, and the assembly efficiency is improved; secondly, if tools such as a screwdriver and the like are not used for assisting, the airplane can be assembled difficultly, and even the airplane can not be assembled; and thirdly, if tools such as a screwdriver and the like are left on the airplane, potential safety hazards exist, and the flying safety of the airplane is threatened.

Disclosure of Invention

The utility model aims to overcome current equipment mode and have that the assemble duration is longer, and is inefficient, and the operation degree of difficulty is great during the assembly, has the hidden danger scheduling problem of security, provides an unmanned aerial vehicle wing body connection structure.

In order to achieve the purpose, the utility model discloses a T type stand of setting in the wing bottom to and the U type groove of seting up at the wing afterbody, be provided with the U type fixture block that is used for fixed T type stand on the fuselage, preset the screw hole that corresponds with U type groove position on the fuselage.

The T-shaped upright post is arranged on the front side of the bottom of the wing.

T type stand and U type fixture block all have two, two T type stand parallel arrangement, and two U type fixture blocks set up the both sides at the fuselage respectively.

The U-shaped groove is connected with the threaded hole through a screw.

The screw is a dish cap screw.

The U-shaped clamping block is rigidly fixed with the machine body.

The T-shaped upright post is rigidly fixed with the wing.

Compared with the prior art, the utility model discloses a T type stand cooperatees with U type fixture block, the front portion of fixed fuselage and wing, cooperate through U type groove and screw hole, the afterbody of fixed fuselage and wing, when the assembly, only need keep flat on the fuselage with wing alignment position, the lower surface of wing and the upside plane of fuselage laminate completely, manual forward flat push wing, go into U type fixture block until T type stand card completely, U type groove on the wing is just in time relative with the screw hole on the fuselage this moment, this structure has reduced the operation degree of difficulty of unmanned aerial vehicle wing body equipment, aircraft assembly efficiency is improved, the risk of reliability and security has also been reduced simultaneously.

fig. 3 is a schematic structural view of the middle body of the present invention;

FIG. 4 is a schematic structural view of a screw according to the present invention;

wherein, 1, a screw; 2. a body; 3. an airfoil; 4. a U-shaped buckle; 5. a T-shaped upright post; 6. a threaded hole; 7. a U-shaped groove.

Detailed Description

The present invention will be further explained with reference to the accompanying drawings.

Referring to fig. 1, 2 and 3, the utility model discloses a T type stand 5 of setting in 3 bottoms of wing to and the U type groove 7 of seting up at 3 afterbody of wing, be provided with the U type fixture block 4 that is used for fixed T type stand 5 on the fuselage 2, preset on the fuselage 2 and correspond with U type groove 7 position screw hole 6. T type stand 5 and U type fixture block 4 all have two, and T type stand 5 sets up the front side in 3 bottoms of wing, two T type stand 5 parallel arrangement, and two U type fixture blocks 4 set up respectively in the both sides of fuselage 2. The U-shaped groove 7 is connected with the threaded hole (6) through a screw 1. The U-shaped fixture block 4 is rigidly fixed with the fuselage 2, and the T-shaped upright post 5 is rigidly fixed with the wing 3.

Referring to fig. 4, the screw 1 is preferably a cap screw.

During assembly, the wing 3 is flatly placed on the fuselage 2 in an aligned position, the lower surface of the wing 3 is completely attached to the upper side plane of the fuselage 2, the wing 3 is horizontally pushed forwards manually until the T-shaped upright post 5 is completely clamped into the U-shaped clamping block 4, and at the moment, the U-shaped groove in the wing 3 is just opposite to the threaded hole 6 in the fuselage 2. Finally, the cap screw is manually screwed into the threaded hole 6 of the fuselage 2 until the cap of the screw 1 is completely pressed on the U-shaped groove, so that the whole process of assembling the wing and the fuselage is completed.
