Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative labor fall within the scope of protection of the present application. The embodiments of the present application will be described in detail below in combination with the drawings.

[0027] The following will be described in conjunction with the accompanying drawings Figs. 1-2 The present application will be further described in detail.

[0028] The first aspect of the present application provides a rope-based unmanned aerial vehicle take-off device, comprising: a slide wire 1 and a slide block 2.

[0029] Specifically, the upper end of the slide wire 1 is fixedly installed on a high-altitude element 3, which can be a high-altitude hot air balloon or a mounting rack with a certain height; the slide block 2 is fixedly installed on the rear side of the center of gravity of the unmanned aerial vehicle 4, the slide block 2 is in sliding connection with the slide wire 1, and the slide block 2 can be detached from the lower end of the slide wire 1.

[0030] In a preferred embodiment of the present application, the slide wire 1 is a rigid element, which can be a steel cable, which can better meet the unmanned aerial vehicle take-off attitude retention.

[0031] In a preferred embodiment of the present application, two slide blocks 2 are arranged on the centerline of the belly of the unmanned aerial vehicle 4, and the two slide blocks 2 are matched with one slide wire 1. In another embodiment of the present application, two slide blocks 2 are symmetrically arranged on both sides of the centerline of the belly of the unmanned aerial vehicle 4, and the two slide blocks 2 are one-to-one corresponding to two slide wires 1. It can be understood that the arrangement of the slide block 2 and the slide wire 1 in the present application is not limited to the above two forms, and can be reasonably selected according to the actual needs of the unmanned aerial vehicle.

[0032] The rope-based unmanned aerial vehicle take-off device of the present application, the relative sliding distance between the slide block 2 and the slide wire 1 is at least L:

[0033] L = V2 / 2g

[0034] Wherein, V is the vertical tail speed of the unmanned aerial vehicle, and g is the acceleration of gravity.

[0035] That is, the lowermost slide block 2 can slide at least L distance before being detached from the lower end of the slide wire 1.

[0036] Based on the above rope-based unmanned aerial vehicle take-off device, the second aspect of the present application provides a rope-based unmanned aerial vehicle take-off method, the method comprising:

[0037] The unmanned aerial vehicle 4 is installed on the high-altitude element 3, and the rope-based unmanned aerial vehicle take-off device is assembled.

[0038] The unmanned aerial vehicle 4 is thrown from the high-altitude element 3, and the unmanned aerial vehicle 4 accelerates by gravity, and after reaching the speed of the unmanned aerial vehicle tail, the sliding block 2 is detached from the lower end of the sliding rope 1.

[0039] The unmanned aerial vehicle launching method based on the rope of the present application needs to first install the unmanned aerial vehicle 2 on the high-altitude element 3, such as a high-altitude hot air balloon, and the high-altitude hot air balloon brings the unmanned aerial vehicle 4 to a high altitude, and the unmanned aerial vehicle 4 is thrown, and the unmanned aerial vehicle 4 accelerates by gravity, so that the unmanned aerial vehicle 4 reaches the required take-off speed. Because the unmanned aerial vehicle 4 has a low speed at the beginning of the throwing, the attitude of the unmanned aerial vehicle 4 cannot be controlled, and therefore the sliding rope 1 and the sliding block 2 are designed to assist in controlling the attitude of the unmanned aerial vehicle 4 in the initial stage of the throwing. Because the sliding block 2 is designed on the rear side of the center of gravity of the unmanned aerial vehicle 4, when the attitude of the unmanned aerial vehicle 4 deviates from the direction of gravity, the sliding block 2 will generate a moment on the machine body, so that the attitude of the unmanned aerial vehicle 4 returns to the direction of gravity.

[0040] The unmanned aerial vehicle launching device and method based on the rope of the present application are suitable for relatively complex occasions, and can reduce the demand for runways and launching devices. The present application enriches the use conditions of unmanned aerial vehicles, and can be reused and has a lower cost compared with conventional take-off and landing methods.

[0041] The above is only a specific embodiment of the present application, but the protection scope of the present application is not limited thereto, and any person skilled in the art can easily think of changes or replacements within the technical scope disclosed in the present application, which should be covered within the protection scope of the present application. Therefore, the protection scope of the present application should be subject to the protection scope of the claims.
