Description

Technical Field

[0001] The present invention relates to the technical field of unmanned aerial vehicles, and in particular to a rotary locking type machine head suitable for modular unmanned aerial vehicles. Background Art

[0002] At present, the connection between the nose and the fuselage of the UAV is mainly connected by bolts between the bulkheads (see Figure 1 ), the advantage of this method is that the connection is tighter and the reliability is strong, but the disadvantage is also obvious, the disassembly and assembly is complicated and cannot be disassembled and assembled quickly. Summary of the invention

[0003] The purpose of the present invention is to provide a rotary locking head suitable for a modular drone in view of the defects and shortcomings of the prior art.

[0004] To achieve the above-mentioned purpose, the technical solution adopted by the present invention is: a rotating locking head suitable for modular unmanned aerial vehicles, including a fuselage and a head, and its innovation lies in: a plurality of positioning grooves are arranged in a ring array at the bulkhead of the fuselage, and the positioning groove is an L-shaped structure as a whole, including an inlet part and a locking part; a positioning ring is arranged on the rear end face of the head, and a plurality of positioning protrusions are arranged in a ring array on the outer ring of the positioning ring, and the number of the positioning protrusions is consistent with that of the positioning grooves, and they correspond one to one, and the positioning protrusions are embedded in the positioning grooves and then rotated to be fixed.

[0005] Furthermore, a plurality of buckles are arranged on the surface of the fuselage, and a plurality of hooks are arranged on the surface of the head. The buckles and hooks are of the same number and correspond one to one, and the two cooperate with each other to limit and fix the fuselage and the head.

[0006] Furthermore, the number of the positioning protrusions and the number of the positioning grooves are at least three respectively.

[0007] Furthermore, the number of the buckles and the number of the hooks are at least two respectively.

[0008] After adopting the above structure, the beneficial effects of the present invention are:

[0009] The present invention can realize the rapid disassembly and assembly of the fuselage and the head by setting the positioning groove, the positioning ring and the positioning protrusion. Compared with the traditional bolt connection, the present invention is faster, more reliable, more efficient, and convenient to position, does not need to use extra tools for installation, and reduces the installation cost.

[0014] The present invention will be further described below in conjunction with the accompanying drawings.

[0015] In order to make the purpose, technical solution and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods. It should be understood that the specific implementation methods described herein are only used to explain the present invention and are not used to limit the present invention.

[0016] See also Figure 1-2 A rotary locking nose suitable for modular UAVs includes a fuselage 1 and a nose 2. A plurality of positioning grooves 3 are arranged in a circular array at the bulkhead of the fuselage 1. The positioning grooves 3 are L-shaped structures as a whole, including an inlet portion 31 and a locking portion 32. A positioning ring 4 is arranged on the rear end face of the nose 2. A plurality of positioning protrusions 5 are arranged in a circular array on the outer ring of the positioning ring 4. The number of the positioning protrusions 5 is consistent with that of the positioning grooves 3, and they correspond one to one. The positioning protrusions 5 are inserted into the positioning grooves 3 and then rotated to be fixed. Specifically, when the fuselage 1 and the nose 2 are spliced, the positioning protrusions 5 first enter the locking portion 32 from the inlet portion 31, and then the positioning protrusions 5 are rotated to the bottom of the locking portion 32 by rotating the body 2, so that the splicing of the fuselage 1 and the nose 2 can be completed, and the rapid disassembly and assembly of the fuselage 1 and the nose 2 can be realized. Compared with the traditional bolt connection, the present invention is faster, more reliable and more efficient.

[0017] In this embodiment, a plurality of buckles 6 are provided on the surface of the body 1, and a plurality of hooks 7 are provided on the surface of the head 2. The buckles 6 and hooks 7 are of the same number and correspond to each other, and the two cooperate with each other to limit and fix the body 1 and the head 2. After the body 1 and the head 2 are rotated and fixed by the positioning protrusion 5 and the positioning groove 3, the buckles 6 and hooks 7 are used to limit and fix them, and the splicing can be completed. It is convenient and quick, and no extra tools are required for installation, which reduces the installation cost.

[0018] In this embodiment, the number of the positioning protrusions 5 and the number of the positioning grooves 3 are at least three, respectively, to ensure that the force between the fuselage 1 and the head 2 is uniform.

[0019] In this embodiment, the number of buckles 6 and hooks 7 is at least two, respectively, so as to ensure the stability after the fixed connection.

[0020] The above description is only used to illustrate the technical solution of the present invention rather than to limit it. Other modifications or equivalent substitutions made to the technical solution of the present invention by ordinary technicians in this field should be included in the scope of the claims of the present invention as long as they do not depart from the spirit and scope of the technical solution of the present invention.
