Detailed implementation manners

[0025] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Apparently, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0026] Figures 1-4 As shown, the present invention provides a floating pontoon mounting structure for an amphibious UAV, which specifically includes a hanging bracket disposed between the UAV housing 1 and a pair of floating pontoons 2. By controlling the deformation of the hanging bracket 3, the floating pontoon 2 can be controlled to approach or move away from the UAV housing 1, facilitating the state change of the amphibious UAV during operation and storage.

[0027] The hanging bracket 3 can adopt a telescopic rod. An electric cylinder or a pneumatic cylinder is assembled under the UAV housing 1, and the telescopic rod is driven by the electric cylinder or the pneumatic cylinder. The lower end of the telescopic rod is fixedly connected to the floating pontoon 2, that is, the lifting of the floating pontoon 2 can be conveniently controlled (the structure is simple and not shown in the figure).

[0028] In addition, other solutions can also be adopted for the hanging bracket 3 and the drive unit 4. The hanging bracket 3 includes an upper arm 31 and a lower arm 32. The upper end of the upper arm 31 is hinged to the lower side of the UAV housing 1, the lower end of the upper arm 31 is hinged to the upper end of the lower arm 32, and the lower end of the lower arm 32 is hinged to the floating pontoon 2. Moreover, hanging brackets 3 are installed between both ends of the floating pontoon 2 in the length direction and the UAV housing 1. By the relative rotation of the upper arm 31 and the lower arm 32 to approach and move away, the approach and separation between the UAV housing 1 and the floating pontoon 2 are controlled.

[0029] The drive unit 4 includes a bidirectional screw 5. Threads are symmetrically arranged along the middle of the bidirectional screw 5. At the same time, moving rings 51 are symmetrically installed on the bidirectional screw 5. Retractable rods 52 are symmetrically hinged to the outside of the moving rings 51. The end of the retractable rod 52 far from the moving ring 51 is fixedly connected to the hinge shaft between the upper arm 31 and the lower arm 32;

[0030] When the bidirectional screw 5 rotates, at this time, the moving ring 51 moves along the screw under the restriction of the retractable rod 52;

[0031] When the moving rings 51 move relative to each other, at this time, the upper arm 31 and the lower arm 32 rotate towards each other and approach, and the retractable rod 52 drives the hanger 3 to contract;

[0032] When the moving rings 51 move away from each other, at this time, the upper arm 31 and the lower arm 32 rotate away from each other and open, and the retractable rod 52 drives the hanger 3 to extend;

[0033] That is, the lifting of the floating boat 2 below the UAV is realized.

[0034] In addition, the driving unit 4 further includes a power assembly for controlling the forward and reverse rotation of the bidirectional screw 5. The power assembly specifically includes a driving wheel 6, a driven wheel 8 and a synchronous belt 7. The driven wheel 8 is coaxially fixed in the middle of the bidirectional screw 5. An installation box 11 is preset below the UAV housing 1. The driving wheel 6 is rotatably installed in the installation. The driving wheel 6 and the driven wheel 8 are connected by a synchronous belt 7. At the same time, a motor 10 for driving the driving wheel 6 is fixed in the installation box 11.

[0035] However, since the bidirectional screw 5 will also move up and down during the lifting process of the floating boat 2, a pair of slide rails 13 are also installed in the installation box 11. The slide rails 13 specifically include two slide rail seats and a guide rod. A bearing seat 131 is slidably assembled on the guide rod. A tension pulley 9 is installed between the two bearing seats 131. The tension pulley 9 is pressed against the inner side of the synchronous belt 7. A thrust spring 132 is also sleeved on the guide rod. The two ends of the thrust spring 132 are respectively abutted against the slide rail seat and the bearing seat 131;

[0036] When the driven wheel 8 rises or falls with the bidirectional screw 5, through the compression and extension deformation of the thrust spring 132, the tension pulley 9 enables the synchronous belt 7 to always maintain a tensioned state between the driving wheel 6 and the driven wheel 8, so as to realize the continuous and stable control of the rise and fall of the floating boat 2.

[0037] In addition, both ends of the bidirectional screw 5 penetrate through the installation box 11, and a vertically extending avoidance slideway is preset on the installation box; during the up and down displacement of the bidirectional screw 5, the inner wall of the avoidance slideway slides and abuts, preventing the bidirectional screw 5 from displacing in other directions, thereby improving the transmission stability during the lifting process of the floating boat 2.

[0038] The working principle of the present utility model is:

[0039] When it is necessary to control the lifting of the floating boat 2, the motor 10 is started to rotate forward or backward, and at the same time, the forward or reverse rotation of the bidirectional screw 5 is controlled through the driving wheel 6, the synchronous belt 7 and the driven wheel 8, and further the movement of the moving ring 51 on the bidirectional screw 5 is realized;

[0040] When the moving rings 51 move relative to each other, the floating boat 2 moves upward;

[0041] When the moving rings 51 move away from each other, the floating boat 2 moves downward.

[0042] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or equivalently replace some of the technical features. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
