Description

Technical Field

[0001] The invention relates to the technical field of unmanned aerial vehicle equipment, and in particular to an unmanned aerial vehicle frame structure used for a single-soldier flying machine. Background Art

[0002] Unmanned aircraft, also known as "drones", are unmanned aircraft that are controlled by radio remote control equipment and self-contained program control devices. There is no cockpit on the aircraft, but it is equipped with autopilots, program control devices and other equipment. Personnel on the ground, on ships or at the remote control station of the mother aircraft use radar and other equipment to track, locate, remotely control, telemeter and digitally transmit it. It can take off like an ordinary aircraft or be launched into the air with a booster rocket under radio remote control, or it can be taken into the air by the mother aircraft for flight. When recovered, it can land automatically in the same way as an ordinary aircraft landing process, or it can be recovered by remote control with a parachute or a blocking net. It can be used repeatedly many times. It is widely used in aerial reconnaissance, surveillance, communication, anti-submarine, electronic interference, etc.

[0003] The existing single-soldier cross-country drones are of higher flight speed and flexibility than ordinary drones, and their speed can even reach 200 kilometers per hour. In order to provide qualified power, existing cross-country drones often need to add a large number of brushless motors and propellers or increase the size of propellers and the output power of motors. However, the equipment exposed outside the frame will increase the flight resistance of the cross-country drone due to air resistance, which will in turn reduce the flight power. Moreover, when objects need to be transported, it is often necessary to install a corresponding carrying platform at a later stage, which makes it inconvenient to expand the load at any time. Summary of the invention

[0004] In view of the deficiencies in the prior art, the present invention provides a UAV frame structure for a single-soldier cross-country drone, which solves the problem of excessive wind resistance and inability to expand the load at any time caused by the fixed structure of the frame of the prior cross-country drone.

[0006] The main frame mechanism includes a top frame plate, a bottom frame plate, a connecting end column, a fixed wind tail, an extension column, a reinforcement shaft column, a top-controlled brushless motor, a protective cover, a ventilation slot and a side-controlled brushless motor. The four sides of the bottom of the top frame plate are fixedly connected to the bottom frame plate through the connecting end columns. A group of extending columns are fixedly connected to the left and right parts between the top frame plate and the bottom frame plate. The top frame plate and the reinforcement shaft column are fixedly connected to the reinforcement shaft column. A group of ventilation slots are arranged on the four side ends between the top frame plate and the bottom frame plate. A group of side-controlled brushless motors are fixedly connected to the four side ends between the bottom frame plate and the top frame plate.

[0007] Preferably, the top center of the top frame plate is fixedly connected to the wind-fixing tail wing, and the front side between the top frame plate and the bottom frame plate is fixedly connected to a protective cover.

[0008] Preferably, the two groups of extending pillars are arranged in a left-right symmetrical relationship, and the outer sides of the two groups of extending pillars are fixedly connected to a group of top-controlled brushless motors.

[0009] Preferably, the auxiliary mechanism includes a rotating shaft seat, a two-way rotating bracket rod, a connecting bracket rod, a limiting slide groove, a fastening threaded rod, an additional plate, a rotating shaft column, an auxiliary fixing rod, a rotating handle and an internal threaded column. The four groups of rotating shaft seats are evenly fixedly connected to the four sides of the bottom of the bottom frame plate, the two front groups of rotating shaft seats are respectively rotatably connected to a group of two-way rotating bracket rods, the bottoms of the two groups of two-way rotating bracket rods are respectively rotatably connected to the left and right sides of the additional plate, the front of the left and right sides of the additional plate are respectively rotatably connected to a group of auxiliary fixing rods through a group of rotating shaft columns, a group of limiting slide grooves are respectively arranged inside the two groups of two-way rotating bracket rods, and the upper parts of the outer side walls of the two groups of auxiliary fixing rods are respectively fixedly connected to a group of internal threaded columns.

[0010] Preferably, the two groups of rotating shaft seats at the rear side are respectively rotatably connected to a group of connecting bracket rods, and the bottoms of the two groups of connecting bracket rods are respectively rotatably connected to the left and right sides of the additional plate through a group of rotating shaft columns.

[0011] Preferably, the two groups of auxiliary fixing rods are respectively slidably connected to a group of limiting slide grooves through a group of internal threaded columns, the insides of the two groups of internal threaded columns are respectively threadedly connected to a group of fastening threaded rods, and the outer ends of the two groups of fastening threaded rods are respectively fixedly connected to a group of internal threaded columns.

[0012] Preferably, the two groups of limiting slide grooves respectively transversely penetrate a group of bidirectional rotating bracket rods.

[0013] Preferably, the four groups of side-controlled brushless motors are respectively arranged to be fixed at an angle of 45 degrees.

[0014] Working principle: First, four sets of connecting end columns are installed between the top frame plate and the bottom frame plate, and the top frame plate and the bottom frame plate are suspended. A set of inclined 45 The side-controlled brushless motors with fixed heights, the power provided by the four sets of side-controlled brushless motors can drive the drone to rotate horizontally for forward movement, and the top-controlled brushless motors fixed on both sides of the frame by extending pillars can provide lifting power for the drone. This structure fixes the four sets of side-controlled brushless motors that can provide forward power inside the frame, and the central part between the top frame plate and the bottom frame plate is fixed overhead by reinforcing shaft columns.
