Detailed implementation manners

[0035] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the drawings in the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, rather than all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present invention. Embodiment 1:

[0036] As Figures 1-4 shown, the present invention provides a drone housing, including a fuselage 1, an arm 5, and a chassis 8. The fuselage 1 includes a top cover 2, a frame 3, and a bottom box 4 that are detachably connected in sequence from top to bottom. The arm 5 and the chassis 8 are both installed on the frame 3.

[0037] The frame 3 is a rectangular structure fixed by metal material pipe fittings. The top cover 2 is made of plastic and is detachably installed on the frame 3. The bottom box 4 is installed on the lower side of the frame 3. By disassembling and installing the top cover 2, operations such as maintenance, replacement, disassembly, and assembly of the components installed in the bottom box 4 can be conveniently performed.

[0038] A pair of limit pieces 31 are installed on the frame 3. The limit pieces 31 are fixedly installed on the inner wall of the frame 3 by means of welding, screws, etc., and the limit pieces 31 are relatively close to one end of the frame 3 in the length direction. A limit groove 32 is preset on the limit piece 31 towards the other end of the frame 3 in the length direction. A pair of limit rods 22 extend inside the lower part of the top cover 2. When the top cover 2 is installed on the frame 3, the limit rods 22 are clamped in the limit groove 32, thereby limiting the movement of one end of the top cover 2 in the length direction. At the same time, a male buckle 23 and a female buckle 33 are respectively installed on the other end of the top cover 2 and the frame 3. By controlling the connection and separation between the male buckle 23 and the female buckle 33, the disassembly and assembly of the top cover 2 on the frame 3 can be conveniently realized.

[0039] Side plates 41 are fixedly installed on the opposite sides inside the frame 3, and a bottom plate 42 is fixedly installed between the side plates 41. The side plates 41 and the bottom plate 42 form a bottom box 4 for supporting the battery 9. The bottom plate 42 is composed of multiple small plates fixedly spliced continuously. An upward-opening V-shaped support groove is formed between the small plates. The opening angle of the support groove matches the structure of the battery 9, so that two small plates support the battery 9. When multiple batteries 9 are placed in the bottom box 4, the batteries 9 are inserted into the bottom box 4 obliquely in sequence along the horizontal direction, avoiding direct stacking of the batteries 9 up and down. At the same time, a part of the top cover 2 bulges upward to form a receiving groove 21 to avoid the part of the battery 9 protruding from the bottom box 4, realizing the installation of the battery 9 in the fuselage 1.

[0040] Machine arms 5 are installed at the four corners of the frame 3. The machine arm 5 includes a fixed seat 51 fixedly installed outside the four corners of the frame 3. An arm tube 52 is rotatably installed on the fixed seat 51. When the arm tube 52 rotates and unfolds, a limit component (the limit component can adopt various conventional technical structures, such as bolts and nuts, etc.) is preset on the fixed seat 51 for controlling the arm tube 52 to remain fixed.

[0041] In addition, every two arm tubes 52 can be folded on both sides of the frame 3 respectively. The arm tubes 52 on the same side are folded obliquely upward or obliquely downward respectively, and an avoidance interval is left between the arm tubes 52 on the same side. At the same time, elastic retaining rings 6 for respectively fixing the four arm tubes 52 are fixed on the outside of the frame 3. When the drone is not in use, the arm tubes 52 can be rotated and clamped in the elastic retaining rings 6 to reduce the storage space requirement.

[0042] A hoisting assembly 7 is detachably installed at the non-articulated end of the arm tube 52. The hoisting assembly 7 is used to fixedly install the floating boat 12. Specifically, the hoisting assembly 7 includes a sleeve base 71, an upper suspension seat 72, a suspension rod 73, and a lower suspension seat 74 that are arranged in sequence from top to bottom. Among them, the sleeve base 71 is sleeved and fixed on the arm tube 52. A track is provided on the lower side of the sleeve base 71. A chute that is inserted and matched with the track is provided at the upper end of the upper suspension seat 72. The upper suspension seat 72 can be fixed on the track by bolts and nuts. An upper socket is preset on the lower side of the lower suspension seat 74. The upper end of the suspension rod 73 is detachably fixed in the upper socket. A lower socket is preset at the upper end of the lower suspension seat 74. The lower end of the suspension rod 73 is detachably fixed in the lower socket.

[0043] The chassis 8 includes four support rods 81 whose upper ends are respectively fixed to the lower sides of the four corners of the machine frame 3. Four stabilizing rods 82 are installed between the support rods 81. The two ends of the stabilizing rods 82 can be fixed to the support rods 81 or to other stabilizing rods 82. And a rectangular space is formed among the four stabilizing rods 82.

[0044] Stabilizing rods 83 are installed on at least two of the stabilizing rods 82. A hinge seat 84 that can rotate is provided at one end of the stabilizing rod 83 away from the stabilizing rod 82. Embodiment 2:

[0045] As Figures 1-4 shown, a four-axis amphibious UAV includes a battery 9 and other control components installed in the fuselage 1. An electronic speed controller and a motor 10 are installed on the arm 5. A rotor 11 is installed on the motor 10.

[0046] A floating boat 12 is detachably installed under the lower suspension seat 74. At the same time, the hinge seat 84 is installed on the floating boat 12. Through the lower suspension seat 74 and the hinge seat 84, the floating boat 12 can be stably installed at the bottom of the UAV.

[0047] The above are only the preferred embodiments of the present utility model and are not used to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements on some of the technical features.
