It will be appreciated that the receptacle 111 is sized and shaped to match the shape and size of the GPS module 20. The accommodating portion 111 has an opening structure, and according to fig. 2, a cover plate 30 may be disposed thereon, and the cover plate 30 is made of a non-metal material and covers the opening structure. In other embodiments, the accommodating portion 111 may be protruded relative to the surface of the upper housing 11, for example, the accommodating portion 111 may be disposed on the top surface of the upper housing 11, the accommodating portion 111 may have an opening structure, a cover plate 30 may be disposed thereon, and the cover plate 30 may be made of a non-metal material and covers the opening structure. The receptacle 111 is sized and shaped to match the shape and size of the GPS module 20. The receiving portion 111 of the protrusion in this embodiment may be made of metal or nonmetal, and preferably, the material of the receiving portion 111 is the same as that of the upper case 11.

The first connecting portion 112 is used to connect the upper case 11 and the head cap 13. In the present embodiment, the number of the first connection portions 112 is two. Of course, the number of the first connecting portions 112 may be set according to actual needs, which is not limited in the present invention.

The lower case 12 is provided on the bottom-facing side of the main body 40, and the lower case 12 is also connected to the hood 13. The lower case 12 has a second connecting part 121, and the second connecting part 121 is used to connect the lower case 12 and the head cap 13. In the present embodiment, the number of the second connection portions 121 is two. Of course, the number of the second connection portions 121 may be set according to actual needs, which is not limited in the present invention. In the present embodiment, specifically, the upper housing 11 is disposed on one side of the drone 100 facing the sky when in a normal flight state; the lower housing 12 is disposed on one side of the unmanned aerial vehicle 100 facing the ground direction when in a normal flight state.

The head cap 13 has a protrusion 131 and a plurality of third connecting parts 132 for connecting with the upper case 11 and the lower case 12. The protrusion 131 may have a receiving space, so that the metal case 10 may have a larger volume; the main body portion 40 may be made to have greater design flexibility. The plurality of third connecting portions 132 are respectively matched with the first connecting portions 112 of the upper housing 11 and the second connecting portions 121 of the lower housing 12 in a one-to-one correspondence manner. In the present embodiment, the plurality of third connecting parts 132 are connected to the first connecting part 112 and the second connecting part 121 by a plurality of fixing head cap screws 14, respectively. Of course, the third connecting portion 132 may be fixedly connected to the first connecting portion 112 and the second connecting portion 121 by other methods, such as a snap connection, which is not limited in the present invention.

In the present embodiment, the head cover 13, the upper case 11, and the lower case 12 are all made of a metal material. Preferably, the head cover 13, the upper housing 11 and the lower housing 12 are made of the same metal material, which may be aluminum alloy or magnesium alloy, or may be other types of light metals or light metal alloys. Of course, the head cover 13, the upper housing 11 and the lower housing 12 may be made of different metal materials, which is not limited in the present invention.

In addition, the fixing head cap screw 14 is also made of metal, and connects the head cap 13, the upper shell 11 and the lower shell 12 into an integral metal shell; meanwhile, the hood 13 and the upper and

lower shells

11 and 12 are at the same potential (also called "equipotential" or "equipotential grounding"). The metal housing 10 can well shield other modules of the drone, routing between modules, and electromagnetic interference caused by magnetic fields in the space outside the fuselage.

The GPS module 20 is used for receiving satellite signals and thereby positioning its own position. The GPS module 20 is accommodated in the accommodating portion 111 of the upper case 11, and is connected to the upper case 11 by fixing GPS screws 21. In this embodiment, the GPS fixing screw 21 is made of metal, and the GPS fixing screw 21 fixes the GPS module 20 and the upper case 11, so that the GPS module 20 and the upper case 11 have the same electric potential. The GPS module 20 is disposed in the accommodating portion 111, and can shield electromagnetic interference of other modules of the unmanned aerial vehicle 100, and can also shield electromagnetic interference generated by routing of the other modules.

Of course, the GPS module 20 may be connected to the upper case 11 by other means, as long as the GPS module 20 can be fixed in the accommodating portion 111 and the GPS module 20 and the upper case 11 are at the same time electrically equalized, which is not limited in the present invention.

The cover plate 30 covers the upper portion of the GPS module 20. Specifically, the cover plate 30 covers an opening of the accommodating portion 111, and is disposed to match the opening of the accommodating portion 111. In the present embodiment, the cover plate 30 is made of a non-metal material, and specifically, the cover plate 30 is made of a plastic material because the plastic material does not block the GPS module 20 from receiving satellite signals. Of course, the cover plate 30 may also be made of other materials that do not block the GPS module 20 from receiving satellite signals, which is not limited in the present invention.

The main body portion 40 includes a power module 41 and a plurality of circuit boards (not shown). The power module 41 supplies power to the GPS module 20 and other power consuming components on the drone 100.

In the present embodiment, the negative electrode of the power module 41 is connected to the metal casing 10, and since the potential of the negative electrode of the power module 41 is zero, when the metal casing 10 is connected to the negative electrode of the power module 41, the potential of the metal casing 10 can also be zero. The GPS module 20 and the plurality of circuit boards are electrically connected to the metal housing 10, respectively, so that the sensors and processors on the plurality of circuit boards have the same zero potential reference as the GPS module 20, thereby reducing common mode radiated interference.

According to the unmanned aerial vehicle provided by the embodiment of the invention, the metal shell is arranged outside the unmanned aerial vehicle, so that the strength of the body is increased, and meanwhile, the metal shell can shield electromagnetic interference generated by other modules of the unmanned aerial vehicle, routing among the modules and the like. In addition, the accommodating part is arranged at the top of the metal shell to accommodate the GPS module, so that the metal shell and the GPS module are in the same electric potential, and the GPS module is not prevented from receiving GPS signals while a better electromagnetic interference resisting effect is achieved.

In addition, those skilled in the art should recognize that the foregoing embodiments are illustrative only, and not limiting, and that appropriate changes and modifications can be made without departing from the spirit and scope of the invention as defined by the appended claims.
