The technical scheme of the invention is further defined in that the locking device comprises a hasp arranged on the outer side of the section of the main case and a hasp fixing end arranged on the outer side of the section of the nose cover, and the hasp fixing end are matched for use.

Furthermore, the anti-dislocation device comprises a spherical positioning hole arranged on the section of the main case and a positioning ball arranged on the section of the nose cover, and the positioning hole is matched with the positioning ball for use.

Further, the hinge is a 180 ° flip-up hinge.

Furthermore, the section formed at the cutting position of the shell is an inclined section, and the inclined angle of the inclined section is 30-60 degrees.

Furthermore, the shell is in streamline integrated molding and comprises a plurality of longitudinal ridge lines.

The other technical scheme provided by the invention is as follows: an unmanned helicopter includes an integral streamlined housing.

Has the advantages that: according to the integral streamline casing of the electric unmanned helicopter and the unmanned helicopter thereof, the integral streamline design and the front part and the rear part are perfectly matched to effectively reduce wind resistance, the upper end hinge realizes large-angle overturning, the operable space is large, the quick replacement of a battery and the equipment inspection are facilitated, the multiple positioning balls on the joint surfaces of the front part and the rear part better ensure the integral consistency of the casing, and the appearance integrity is high; the cabin door is quickly and effectively locked by the flexible hasp at the lower end; the shell belongs to an externally hung shell, the strength of the shell is effectively improved by the design of a plurality of longitudinal ridge lines, and the shell has the characteristic of light weight.

Detailed Description

The technical solution of the present invention is described in detail below with reference to the accompanying drawings, but the scope of the present invention is not limited to the embodiments.

Example 1: the utility model provides an electronic unmanned helicopter's whole streamlined casing, includes casing 1, casing 1 adopts the streamlined design of integration based on aerodynamic principle, contains many vertical crest lines. In consideration of the structural characteristics of the unmanned helicopter, in the present embodiment, the casing 1 is divided into the main casing 5 and the nose cover 2, the division position forms a tangent plane, the tangent plane is an inclined tangent plane, and the inclination angle is 30-60 °. The main hull 5 is largely longitudinally split and mounted from both sides of the fuselage to the helicopter fuselage and is waterproofed, with minimal disassembly once mounted. The head cover 2 is small and is used for replacing batteries.

The main case 5 and the head cover 2 are connected through a hinge 4, and the hinge 4 is a 180-degree upturning hinge. Meanwhile, the main chassis 5 and the head cover 2 are also locked by at least one set of locking devices. Locking device including set up in the hasp in the 5 tangent planes outsides of mainframe shell with set up in hasp stiff end 7 in the 2 tangent planes outsides of hood, the hasp with hasp stiff end 7 cooperation is used.

In this embodiment, the section is oval-like, the locking devices are provided in a group, and the hinge 4 and the locking devices are respectively provided at both ends of the long axis of the section. If the locking devices are in a plurality of groups, the locking devices are uniformly distributed along the circumferential direction of the tangent plane.

Meanwhile, the embodiment also comprises at least one group of dislocation prevention devices, and when the dislocation prevention devices are a plurality of groups, the dislocation prevention devices are uniformly distributed along the circumferential direction of the section. The anti-dislocation device comprises a spherical positioning hole 6 arranged on the section of the main case 5 and a positioning ball 3 arranged on the section of the nose cover 2, and the positioning hole 6 is matched with the positioning ball 3.

According to the unmanned helicopter comprising the integral streamline housing, the rear main housing 5 is fixedly connected with the helicopter body and is not detached after being assembled. The head cover 2 is only connected with the main case 5 through a hinge 4 and a flexible hasp, and a plurality of positioning balls 3 are arranged on the section of the head cover and are matched with positioning holes 6 of the rear main case. The upper end of the front-end hood can be turned up and closed by 180 degrees through a hinge connected with the rear main shell, so that the battery replacement and the equipment detection are facilitated; the lower end of the cabin door adopts a flexible hasp to realize locking after the cabin door is closed; the fit of the positioning balls and the positioning holes on the joint surface prevents local dislocation of the two parts, thereby realizing streamline lap joint of the whole casing.
