[0001] The utility model relates to the technical field of unmanned aerial vehicles, in particular to an unmanned aerial vehicle positioning device and an unmanned aerial vehicle positioning take-off and landing system. Background Art

[0002] During the landing process of a tethered unmanned aerial vehicle, due to the influence of various factors such as wind force and the accuracy of the control system, it is easy to deviate from the set landing position, resulting in low landing positioning accuracy.

[0035] To make the objectives, technical solutions and advantages of the present utility model clearer, the technical solutions in the present utility model will be clearly and completely described below with reference to the accompanying drawings in the present utility model. Apparently, the described embodiments are some but not all of the embodiments of the present utility model. All other embodiments obtained by those of ordinary skill in the art based on the embodiments in the present utility model without making creative efforts shall fall within the protection scope of the present utility model.

[0036] The following will be combined with Figures 1 to 7 Describe the UAV positioning device and the UAV positioning take-off and landing system provided by the present utility model.

[0037] Refer to Figures 1 to 3 As shown, the UAV positioning device provided by an embodiment of the present utility model includes: a rough positioning assembly 10 and a fine positioning assembly 20.

[0038] The rough positioning assembly 10 includes a first guiding bracket 110 and two second guiding brackets 120 that are circumferentially spaced apart. A guiding groove 111 is formed on the first guiding bracket 110. The guiding groove 111 is used to guide the guiding rod 410 on the landing gear 40 of the drone. An outwardly inclined first inclined guiding portion 121 is formed on the second guiding bracket 120. The first inclined guiding portion 121 is used to guide the bottom of the landing gear 40 of the drone.

[0039] The fine positioning assembly 20 includes a guiding support base 210. The diameter of the guiding support base 210 gradually decreases from bottom to top, so as to form a second inclined guiding portion 211 on the side of the guiding support base 210. The second inclined guiding portion 211 is used to guide the landing gear 40 of the drone.

[0040] The first guiding bracket 110 and the two second guiding brackets 120 are both located on the periphery of the guiding support base 210.

[0041] For the drone positioning device provided by the present utility model, during the entire process of the drone 30 landing, it is only necessary to position the drone 30 above the drone positioning device. Subsequently, the precise self-positioning landing of the drone 30 can be achieved without using any sensors for auxiliary positioning, solving the defect in the prior art that the landing accuracy of the drone 30 is improved by setting multiple high-precision sensors, resulting in a relatively high cost.

[0042] Specifically, by setting the rough positioning assembly 10 and the fine positioning assembly 20, when the drone 30 lands, the bottom of the landing gear 40 of the drone first contacts the two second guiding brackets 120. The first inclined guiding portion on the second guiding bracket 120 drives the drone 30 to move towards the center of the set position. At the same time, the guiding rod 410 on the landing gear 40 of the drone corrects the drone 30 under the guiding action of the guiding groove 111 on the first guiding bracket 110. Then, the mating portion on the landing gear 40 of the drone cooperates with the second inclined guiding portion 211 on the side of the guiding support base 210 to achieve the precise self-positioning landing of the drone 30.

[0043] See Figure 2 and Figure 4 As shown, according to some embodiments of the present utility model, the guiding groove 111 includes a guiding section 1111 and a limiting section 1112. The end of the guiding section 1111 is connected to the beginning of the limiting section 1112. The limiting section 1112 is located below the guiding section 1111. By setting the guiding groove 111 as the interconnected guiding section 1111 and limiting section 1112, after the drone 30 is corrected by the guiding groove 111, the limiting section 1112 can be used to perform circumferential limiting on the drone 30 to prevent it from rotating during subsequent positioning or fixing, ensuring its stability.

[0044] Specifically, in this embodiment, when the guide rod 410 of the UAV landing gear 40 reaches the bottom of the limiting section 1112, the mating part of the UAV landing gear 40 just mates with the second inclined guiding part 211. At this time, the first guiding bracket 110 and the guiding support seat 210 can simultaneously support the UAV 30.

[0045] See Figure 2 and Figure 4 As shown, according to some embodiments of the present invention, the first guiding bracket 110 includes a first fixing plate 112 and two first guiding members 113. A first inclined section 1131 and a first straight section 1132 are formed on the first guiding member 113. The end of the first inclined section 1131 is connected to the beginning of the first straight section 1132. The two first guiding members 113 are symmetrically arranged on the first fixing plate 112, and a guiding section 1111 is formed between the two first inclined sections 1131, and a limiting section 1112 is formed between the two first straight sections 1132. By setting the first guiding bracket 110 as a frame structure, on the premise of considering structural stability, the structure of the first guiding bracket 110 is simple, with less material used and light weight, which is convenient for processing, manufacturing and assembly.

[0046] Specifically, the first inclined section 1131 and the first straight section 1132 can be formed by bending metal bars / tubes / profiles. The two ends of the metal bars / tubes / profiles can be connected to the upper surface of the first fixing plate 112 by welding or other means. During installation, the first fixing plate 112 can be fixed at a set position (such as the takeoff and landing platform of the UAV 30) through screws or other components.

[0047] See Figure 2 and Figure 5 As shown, according to some embodiments of the present invention, the second guiding bracket 120 includes a second fixing plate 122 and a second guiding member 123. A second inclined section 1231 and a second straight section 1232 are formed on the second guiding member 123. The end of the second inclined section 1231 is connected to the beginning of the second straight section 1232, and the end of the second straight section 1232 is connected to the second fixing plate 122. Similarly, by setting the second guiding bracket 120 as a frame structure, on the premise of considering structural stability, the structure of the second guiding bracket 120 is simple, with less material used and light weight, which is convenient for processing, manufacturing and assembly.

[0048] Specifically, the second inclined section 1231 and the second straight section 1232 can be formed by bending metal bars / tubes / profiles. The two ends of the metal bars / tubes / profiles can be connected to the upper surface of the second fixing plate 122 by welding or other means. During installation, the second fixing plate 122 can be fixed at a set position (such as the takeoff and landing platform of the UAV 30) through screws or other components.

[0049] SeeFigure 2 As shown, according to some embodiments of the present utility model, the first guiding bracket 110 is disposed opposite to the two second guiding brackets 120. By disposing the first guiding bracket 110 opposite to the two second guiding brackets 120, when the unmanned aerial vehicle 30 lands, the tail of the landing gear 40 of the unmanned aerial vehicle is guided by the two second guiding brackets 120, so that the whole unmanned aerial vehicle 30 moves towards the center of the set position. At the same time, the guiding rod 410 provided at the end of the landing gear 40 of the unmanned aerial vehicle makes the whole unmanned aerial vehicle 30 return to the correct position under the action of the guiding groove 111. During this process, the stability of guiding the unmanned aerial vehicle 30 can be ensured, and the position deviation of the unmanned aerial vehicle 30 during the guiding landing can be prevented.

[0050] Specifically, in this embodiment, the first guiding bracket 110 is disposed opposite to the two second guiding brackets 120, and the two second guiding brackets 120 are respectively located on both sides of the central axis of the guiding groove 111.

[0051] See Figure 3 As shown, according to some embodiments of the present utility model, a plurality of rolling guiding mechanisms are arranged at intervals along the circumferential direction on the side of the guiding support seat 210. The rolling guiding mechanism includes a first connecting rod 212 and a plurality of first rolling members 213. The plurality of first rolling members 213 are sleeved on the first connecting rod 212. By arranging a plurality of rolling guiding mechanisms at intervals along the circumferential direction on the side of the guiding support seat 210, during the process of the guiding rod 410 of the landing gear 40 of the unmanned aerial vehicle cooperating with the guiding groove 111 to make the unmanned aerial vehicle 30 return to the correct position, the sliding friction between the landing gear 40 of the unmanned aerial vehicle and the second inclined guiding portion 211 can be converted into rolling friction through the plurality of first rolling members 213 arranged on the first connecting rod 212, thereby reducing the resistance received during the process of the unmanned aerial vehicle 30 returning to the correct position.

[0052] See Figure 3 As shown, according to some embodiments of the present utility model, the guiding support seat 210 includes an upper support ring 214 and a lower support ring 215 which are arranged at intervals in the vertical direction. A plurality of second connecting rods 216 are arranged at intervals between the upper support ring 214 and the lower support ring 215. The upper support ring 214 and the lower support ring 215 are connected by the plurality of second connecting rods 216; at least some of the adjacent second connecting rods 216 are provided with strengthening connecting rods 217, and the first connecting rod 212 is arranged between the strengthening connecting rod 217 and the lower support ring 215. By arranging the strengthening connecting rod 217, the structural strength of the guiding support seat 210 can be enhanced, so that it does not deform when bearing the unmanned aerial vehicle 30. At the same time, the first connecting rod 212 is located between the strengthening connecting rod 217 and the lower support ring 215, and the first rolling members 213 on the first connecting rod 212 can convert the sliding friction between the landing gear 40 of the unmanned aerial vehicle and the second inclined guiding portion 211 into rolling friction, thereby reducing the resistance received during the process of the unmanned aerial vehicle 30 returning to the correct position.

[0053] Specifically, the diameter of the upper support ring 214 is smaller than that of the lower support ring 215. A plurality of second connecting rods 216 are obliquely connected between the upper support ring 214 and the lower support ring 215. The plurality of second connecting rods 216 can keep the upper support ring 214 and the lower support ring 215 relatively fixed and form the above-mentioned second inclined guiding portion 211. At the same time, the first rolling members 213 provided on the first connecting rod 212 can convert the sliding friction between the drone landing gear 40 and the second inclined guiding portion 211 into rolling friction, thereby reducing the resistance suffered during the process of the drone 30 returning to the correct position.

[0054] Of course, in some embodiments, the first rolling members 213 can also be provided on the second connecting rods 216.

[0055] See Figure 3 As shown, according to some embodiments of the present invention, a plurality of second rolling members 219 are provided on the upper support ring 214. The second rolling members 219 are used to convert the sliding friction between the cable and the upper support ring 214 into rolling friction when the cable is wound or unwound, thereby reducing the frictional resistance when the cable is wound or unwound and preventing wear of the cable and the upper support ring 214.

[0056] Specifically, in this embodiment, the first rolling members 213 and the second rolling members 219 can be rolling members such as rollers or balls.

[0057] See Figure 3 As shown, according to some embodiments of the present invention, a plurality of flexible support members 218 are provided on the guiding support base 210 at circumferential intervals. The flexible support members 218 are used to support the drone landing gear 40. Since a linear limiting section 1112 is formed at the bottom of the guiding groove 111, when the guiding rod 410 of the drone landing gear 40 enters the limiting section 1112, the whole drone 30 will have a small downward drop distance. By circumferentially and intermittently arranging a plurality of flexible support members 218 on the guiding support base 210, the drone landing gear 40 can be flexibly supported to prevent the drone 30 from impacting the guiding support base 210 when landing, resulting in damage to the drone 30 and / or the guiding support base 210.

[0058] Specifically, the flexible support member 218 can be a rubber pad or an airbag, etc.

[0059] Preferably, in this embodiment, an airbag is selected. A plurality of airbag mounting brackets are provided on the guiding support base 210 at circumferential intervals, and the airbag is arranged on the airbag mounting brackets.

[0060] Next, the drone 30 positioning takeoff and landing system provided by the present invention will be described. The drone 30 positioning takeoff and landing system described below can be mutually corresponding and referred to the drone positioning device described above.

[0061] SeeFigure 6 River Figure 7 As shown in Figure 7 , the positioning take-off and landing system for the drone 30 provided by the embodiment of the present invention includes a drone 30 and the drone positioning device described in any one of the above embodiments.

[0062] A drone landing gear 40 is provided at the bottom of the drone 30. One end of the drone landing gear 40 is provided with a guide rod 410 for matching with the guide groove 111, and a matching portion for cooperating with the second inclined guiding portion 211 is formed on the drone landing gear 40.

[0063] For the positioning take-off and landing system of the drone 30 provided by the present invention, due to the adoption of the above-mentioned drone positioning device, during the entire process of the drone 30 landing, it is only necessary to position the drone 30 above the drone positioning device, and subsequent precise self-positioning landing of the drone 30 can be achieved without using any sensors for auxiliary positioning, solving the defect in the prior art that the cost is relatively high by setting multiple high-precision sensors to improve the landing accuracy of the drone 30.

[0064] See Figure 7 As shown in Figure 7 , according to some embodiments of the present invention, a plurality of cooperating rods 420 are provided at intervals on the side of the drone landing gear 40, and the cooperating rods 420 are used to cooperate with the above-mentioned first rolling member 213.

[0065] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit them; although the present invention has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements for some of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the spirit and scope of the technical solutions of the embodiments of the present invention.
