Background

Being equipped with a plurality of rotors on many rotor unmanned aerial vehicle's the fuselage, making many rotor unmanned aerial vehicle have higher lift, and a plurality of rotors distribute in the periphery of unmanned aerial vehicle fuselage, make many rotor unmanned aerial vehicle's area occupied great, be difficult to carry. Therefore current many rotor unmanned aerial vehicle's horn generally adopts detachable grafting structure, dismantles the horn when unmanned aerial vehicle transports or deposits and deposits to reduce unmanned aerial vehicle's area occupied. However, in order to ensure that the horn can smoothly be installed and dismantled, connection structure generally leaves the clearance between fuselage and the horn, and when unmanned aerial vehicle started, connection structure's clearance made the horn take place to rock, reduced unmanned aerial vehicle horn's stability.

Disclosure of Invention

The invention aims to provide a detachable unmanned aerial vehicle arm device, which is used for solving one or more technical problems in the prior art and at least providing a beneficial selection or creation condition.

The technical scheme adopted for solving the technical problems is as follows:

a can dismantle unmanned aerial vehicle horn device includes:

a body;

the mounting seat is connected to the machine body, the position of the machine body relative to the mounting seat is the opposite rear direction, a connecting hole is formed in the front side of the mounting seat, the connecting hole is a conical hole with a large front part and a small rear part, and a first connecting structure is arranged on the outer side wall of the mounting seat;

one end of the connecting rod is provided with a connector, the connector is inserted into the connecting hole, and the shape of the connector is matched with that of the connecting hole;

the connecting piece, its front side connect in the connecting rod, the rear side of connecting piece is equipped with second connection structure, second connection structure with first connection structure can dismantle the connection and make the lateral wall of connector hug closely in the inside wall of connecting hole.

The invention has the beneficial effects that: the mount pad is connected with the fuselage, the connector of connecting rod inserts in the connecting hole of mount pad, the connecting piece is connected with the connecting rod, the second connection structure of connecting piece rear side can be dismantled with first connection structure and be connected the inside wall that makes the lateral wall of connector hug closely the connecting hole, because the connecting hole is big-end-up's bell mouth, the appearance of connector and the shape phase-match of connecting hole, the inside wall of connecting hole centers on the connector round, during the inside wall of connecting hole and the lateral wall butt of connector, eliminate the clearance between the lateral wall of connector and the inside wall of connecting hole, the axis department of connector is assembled to the pressure direction of the lateral wall of connector to the inside wall of connecting hole, thereby make the connecting head firmly be fixed in the connecting hole, prevent that the connector from rocking in the connecting hole, improve the stability of horn.

As a further improvement of the technical scheme, the shape of the connector is a round table structure with a large front part and a small back part, and a gap is reserved between the rear end face of the connector and the inner wall of the rear side of the connecting hole.

The shape of connector is big-end-up's round platform structure, and when second connection structure was connected with first connection structure, the lateral wall of connector hugged closely in the inside wall of connecting hole, leaves the clearance between the rear end face of connector and the rear side inner wall of connecting hole, avoids the rear side inner wall of connecting hole to interfere the rear end face of connector to ensure that the lateral wall of connector and the inside wall of connecting hole keep the butt state.
