Scalable foldable farming of wing protects unmanned aerial vehicle

Technical Field

The utility model relates to an unmanned air vehicle technique field, especially an unmanned aerial vehicle is protected to scalable foldable farming of wing.

Background

Unmanned aerial vehicle is unmanned aerial vehicle for short, is the unmanned vehicles who utilizes radio remote control equipment and self-contained program control device to control, and unmanned aerial vehicle is the general name of unmanned aerial vehicle in fact, can divide into from the technical perspective: compared with manned aircrafts, the unmanned fixed wing aircraft, the unmanned vertical take-off and landing aircraft, the unmanned airship, the unmanned helicopter, the unmanned multi-rotor aircraft, the unmanned umbrella wing aircraft and the like have the advantages of small volume, low manufacturing cost, convenient use, low requirement on the battlefield environment, strong battlefield viability and the like. Since the unmanned aircraft has important significance for future air battles, the research and development work of the unmanned aircraft is carried out in all major military countries in the world. In addition, the unmanned aerial vehicle has wide application and has better development prospect in the industries of police, city management, agriculture, geology, meteorology, electric power, emergency rescue and disaster relief, video shooting and the like.

The use of unmanned aerial vehicles to serve agriculture has rapidly evolved in recent years. When the drone is used in the agricultural field, it is generally used for agriculture and forestry plant protection operations, such as spraying of chemicals, seeds, dusts, etc., and is therefore also called as agricultural drone. Unmanned aerial vehicle is protected to farming has that the operation height is low, drift is few, can hover in the air, need not a great deal of advantages such as special take-off and landing airport, and the downdraft that the rotor produced helps increasing fog and flows the penetrability to crops, and the prevention and cure effect is high, and through remote control operation, sprays the operation personnel and has avoided exposing in the danger of pesticide, has improved and has sprayed the operation security. But because the particularity of work, the loading capacity of unmanned aerial vehicle is protected to farming needs big enough, leads to unmanned aerial vehicle is protected to farming's self volume great, and current unmanned aerial vehicle is protected to farming is fuselage and wing fixed connection formula usually, and can't fold or dismantle, leads to the whole occupation space of unmanned aerial vehicle big, has reduced the portability of its vanning transportation in very big degree, has increased the cost of transportation.

SUMMERY OF THE UTILITY MODEL

Not enough more than, the utility model provides a scalable foldable farming of wing protects unmanned aerial vehicle, its horn can fold down and stretch out and draw back, can effectively reduce its occupation space, not only reduces the cost of transportation, and reduces the collision damage of unmanned aerial vehicle on the way of the transportation, ensures unmanned aerial vehicle's transportation security.

The technical scheme of the utility model is that:

the four horn bodies are arranged around the fuselage symmetrically, the whole horn body can be folded downwards, the lower side of the end part of the horn body is connected with the fuselage through a hinge, the horn body is three sections of telescopic types, and when the three sections of the horn bodies are completely extended, buckles are used for locking every two sections of the joints.

The buckle is a spring buckle, a buckle button is arranged on the machine body and connected with the spring buckle, and when the buckle button is pressed down, a spring inside the spring buckle retracts.

The tail end of the machine arm is provided with a propeller, and the propeller is two double-blade propellers with opposite rotating directions.

The utility model discloses an unmanned aerial vehicle is protected to farming includes fuselage and horn, and the horn passes through hinged joint with the fuselage, and the horn can fold downwards, reduces and transversely occupies the width. Meanwhile, the machine arm body is of a three-section telescopic type, so that the whole length of the machine arm can be reduced, and the machine arm can be accommodated in a vertical space when being folded downwards. In order to facilitate fixing, the telescopic horn is locked by a spring buckle at the joint, and when the three-section horn is pulled open, the spring buckle automatically extends out under the elastic action to lock the horn. In order to facilitate the flexible extension of the machine arm, the spring buckle is controlled by the buckle button, the buckle button can be pressed down, and one key releases the locking of the spring buckle, so that the machine arm is converted into an extensible state from a locking state. The utility model discloses an unmanned aerial vehicle is protected to scalable foldable farming of wing can effectively reduce unmanned aerial vehicle's occupation space, not only makes things convenient for in unmanned aerial vehicle's transportation, can reduce the collision damage of unmanned aerial vehicle in the transportation moreover, ensures the security of unmanned aerial vehicle transportation.

Detailed Description

The conception, the specific structure and the technical effects of the present invention will be further described with reference to the accompanying drawings, so as to fully understand the objects, the features and the effects of the present invention.

Referring to fig. 1 and 3, the utility model discloses a scalable foldable farming of wing protects unmanned aerial vehicle, including fuselage 1 and horn 2, horn 2 is four, and the symmetry sets up around fuselage 1, and horn 2 is whole to be the folding formula downwards, and horn 2 tip downside is connected through hinge 3 with fuselage 1. The tail end of each machine arm 2 is provided with a propeller 5, and the propeller 5 consists of a blade, a motor and a motor bracket. Screw 5 is two rotation direction opposite bilobed screws, constitutes coaxial two rotor structure, and it has higher efficiency of hovering, and has lower induced resistance, and simultaneously, unmanned aerial vehicle's mobility increases to some extent to can guarantee comparatively good stability.

Referring to fig. 2, in order to reduce the overall length of the horn 2 and facilitate the downward folding of the horn 2, the body of the horn 2 is three-segment telescopic, and in order to facilitate the fixing, when the three segments of the horn 2 are completely extended, the joint of each two segments is locked by a buckle 4. In order to facilitate flexible extension and retraction of the horn 2, the buckle 4 is a spring buckle, the body 1 is provided with a buckle button 11, the buckle button 11 is connected with all the spring buckles, when the buckle button 11 is pressed down, locking of all the spring buckles can be released by one key, and the spring in the spring buckle drives the buckle to retract, so that the horn 2 is converted into a freely extendable state from a locking state.

When needs will the utility model discloses an agricultural unmanned aerial vehicle is folding to be dwindled when being used for the transportation, presses buckle button 11 on the fuselage 1 earlier, makes horn 2 trun into free telescopic state by the locking state, inwards promotes four horns 2, makes horn 2 inwards return and contract to the shortest state, then pulls horn 2 downwards, makes horn 2 rotate the vertical state by the horizontality. The length of the unmanned aerial vehicle in the horizontal direction is greatly reduced, so that the unmanned aerial vehicle is convenient to transport, the space occupied by the unmanned aerial vehicle is reduced, and the transportation cost is reduced. Simultaneously, because unmanned aerial vehicle's horn 2 is fold down state, can avoid extending longer, comparatively outstanding horn 2, screw 5 receive collision extrusion injury in the transportation, ensure unmanned aerial vehicle's security in the transportation.

The above disclosure is only for the embodiment of the present invention, however, the present invention is not limited thereto, and any changes that can be considered by those skilled in the art should fall within the protection scope of the present invention.
