Figure 8 The technical solutions in the embodiments of the present application will be described below in conjunction with the accompanying drawings 1 to 3.

[0053] The height of the foot support carried by the unmanned aerial vehicle itself is usually limited, and the distance between the unmanned aerial vehicle body and the bottom is usually low, which limits the use of the unmanned aerial vehicle in the field, for example, when the unmanned aerial vehicle lands on the grass, the grass and dust on the grass are easily sucked into the unmanned aerial vehicle body, causing damage to the unmanned aerial vehicle body.

[0054] Then, in order to solve this technical problem, the prior art usually uses a height-increasing foot support to increase the height of the unmanned aerial vehicle from the ground, but the combination of the height-increasing foot support and the unmanned aerial vehicle body in the prior art is not convenient to disassemble, and the unmanned aerial vehicle body is easily scratched during disassembly.

[0055] To this end, the present application provides a height-increasing foot support for an unmanned aerial vehicle, which aims to increase the height of the unmanned aerial vehicle body from the bottom while conveniently disassembling the height-increasing foot support from the unmanned aerial vehicle body without scratching the unmanned aerial vehicle body.

In an embodiment of the utility model, the first buckle member 112 is arranged on the both sides of the gap 114. The first buckle member 112 is a component protruding upward from the front end surface of the foot stand main body 1 and having a hooking part. The first buckle member 112 is connected with the unmanned aerial vehicle body by hooking the hooking part in the fastening position on the unmanned aerial vehicle body.

[0060] In an embodiment of the utility model, the bottom surface 111 of the groove 11 has a through hole 115 penetrating from its surface to the back, when the heightening foot is assembled on the unmanned aerial vehicle body, the through hole 115 is opposite to the air inlet hole at the bottom of the unmanned aerial vehicle body, to ensure the smooth air inlet of the air inlet hole at the bottom of the unmanned aerial vehicle body.

[0061] According to actual needs, the through hole 115 can have multiple through holes, to facilitate the heat dissipation of the bottom of the unmanned aerial vehicle body.

[0062] It should be further explained that, as shown in Fig. 3, the other side opposite to the bottom surface 111 of the groove 11 has several downward protruding assembling parts 12, which are used for assembling and connecting with external devices, such as assembling and connecting lighting devices, etc.

[0063] In an embodiment of the utility model, as shown in Figs. 3-5, the other end of the foot body 1 is movably connected with a second buckle part 2, specifically, the second buckle part 2 is located at the position of the rear end of the foot body 1. The second buckle part 2 has a clamping part 21 capable of clamping with the clamping position of the unmanned aerial vehicle body; the clamping part 21 has an unlocking position B and a locking position C.

[0064] As shown in Figs. 3-5, the second buckle part 2 further comprises a pressing part 23, the clamping part 21 and the pressing part 23 are connected through a corner connecting part 22, that is, the clamping part 21 and the pressing part 23 are connected by bending, so that the entire second buckle part 2 presents a structure similar to "L".

[0065] As shown in Figs. 3-5, the foot body 1 has a pivot part 116, which is located at the rear end of the foot body 1 and is used for assembling and connecting with the second buckle part 2. Specifically, the pivot part 116 extends from the rear end side of the foot body 1 to the part of the bottom surface 111 close to the rear end. The pivot part 116 has an assembling groove 1162 recessed from its surface in the part of the bottom surface 111, the assembling groove 1162 has a convex column 1163 therein, and the outer periphery of the convex column 1163 is sleeved with a telescopic part 4. In this embodiment, the telescopic part 4 is a spring. In detail, the telescopic part 4 is sleeved on the outer periphery of the convex column 1163, and the end of the telescopic part 4 abuts against the pressing part 23 in the second buckle part 2.

[0066] In use, when the pressing portion 23 in the second buckle 2 is pressed by external force, the clamping portion 21 moves to the unlocking position B to achieve the separation of the clamping portion 21 from the buckling position of the UAV body, thereby achieving the unlocking of the trivet body 1 from the UAV body; when the external force on the second buckle is removed, the second buckle 2 is subjected to the elastic force of itself, that is, the stretching member 4 loses the external pressure and according to its own elastic retraction performance, an acting force is applied to the pressing portion 21, thereby causing the clamping portion 21 to reset to the locking position to achieve the mutual clamping of the clamping portion 21 and the buckling position of the UAV body, thereby achieving the locking connection of the trivet body 1 and the UAV body.

[0067] It should be understood that, as designed, the heightening trivet can be quickly detached from the UAV body by switching the clamping portion 21 between the unlocking position and the locking position. In specific operation, the clamping portion 21 can be moved from the locking position to the unlocking position by pressing the pressing portion 23 with external force, so that the clamping portion 23 is separated from the buckling position on the UAV body, and then the first buckle 112 is separated from the UAV body, thereby achieving the separation of the heightening trivet from the UAV body. In this way, the problem of scratching the UAV body by the first buckle 112 and the second buckle 2 when the heightening trivet is separated from the UAV body can be effectively avoided, and the heightening trivet can be conveniently and quickly detached.

[0068] Further, the connection between the clamping portion 21 and the pressing portion 23 has a through hole 24; that is, the corner connecting portion 22 has a through hole 24. The through hole 24 is inserted with a pin shaft, both ends of the pin shaft are exposed from both sides of the through hole, and the two ends are respectively inserted with the pivot portion 116.

[0069] It should be understood that, as designed, when the user presses the pressing portion 23, the clamping portion 21 can rotate relative to the axis of the through hole 24, thereby achieving the switching of the clamping portion 21 between the unlocking position and the locking position.

[0070] In another embodiment, as Figure 6As shown, the second buckle 2 is in a "U" shape structure, and the two ends of the "U" shape structure correspond to the pressing part 23 and the clamping part 21 respectively. The end of the pressing part 21 extends into the inside of the telescopic part 4, and the other end of the telescopic part 4 is fixed on the support body 1, thereby indirectly realizing that the second buckle 2 of this type is fixedly arranged on the support body 1, and the end of the clamping part 21 is arranged at the buckling position of the unmanned aerial vehicle body.

[0071] In use, the user can pull the pressing part 23 outward to make the clamping part 21 separate from the buckling position on the unmanned aerial vehicle body, thereby realizing the unlocking of the support body 1 and the unmanned aerial vehicle body; on the contrary, when the user removes the pulling force on the pressing part 23, the pressing part 23 moves in the direction opposite to the pulling force direction due to the retraction force of the telescopic part 4, thereby making the clamping part 21 return from the unlocking position to the locking position, so as to realize the quick assembly of the height-increasing support and the unmanned aerial vehicle body.

[0072] In an embodiment of the utility model, as shown in Figure 7 As shown, the support body 1 has a connecting part 13 on both sides; each connecting part 13 is pivotally connected with a support frame 3, and each support frame 3 can generate a folding or unfolding state relative to the support body 1.

[0073] It should be understood that, in this way, when the unmanned aerial vehicle lands, the support frame 3 in the unfolded state can increase the height between the unmanned aerial vehicle body and the landing surface, so as to avoid the sand and dust on the landing surface from entering the unmanned aerial vehicle body.

[0074] However, in another scenario, when the unmanned aerial vehicle flies in the sky, the support frame 3 can be folded to avoid affecting the airflow near the unmanned aerial vehicle body when the unmanned aerial vehicle flies.

[0075] Further, in order to better change the unfolding or folding state of the support frame 3 relative to the support body 1 in actual use, the connecting part 13 has a connecting end 131 extending towards the support frame 3; the connecting end 131 has a connecting through hole 133; the top of the support frame 3 has a through hole 31; and the height-increasing support further comprises a connecting piece 5.

[0076] In the assembly, the connecting piece 5 passes through the connecting through hole 133 and the through hole 31 in sequence to connect the support frame 3 and the support frame body 1 together, and the support frame 3 and the support frame body 1 can rotate relative to the axis of the connecting piece 5, so that the support frame 3 can be folded or unfolded relative to the support frame body 1.

[0077] Further, the connecting part 13 has a fixing piece 132, the top of the support part 32 of the support frame 3 has a first limiting groove 321, and when the fixing piece 132 falls into the first limiting groove 321, the support frame 3 is fixed at the current unfolded angle relative to the support frame body 1.

[0078] It should be understood that when the support frame 3 is unfolded relative to the support frame body 1, the support frame 3 is unfolded to a certain angle so that the fixing piece 132 falls into the first limiting groove 321, and the support frame 3 is fixed at the required unfolded angle by using the static friction between the end of the fixing piece 132 and the first limiting groove 321, so as to prevent the support frame 3 from moving, which can effectively prevent the support frame 3 from being unstable when standing on the landing surface.

[0079] Further, the top of the support frame 3 has a second limiting groove 322, and the fixing piece 132 falls into the second limiting groove 322 to fix the support frame 3 at the current folded angle relative to the support frame body 1.

[0080] It should be understood that when the support frame 3 is folded relative to the support frame body 1, the support frame 3 is folded to a certain angle so that the fixing piece 132 falls into the second limiting groove 322, and the support frame 3 is fixed at the required folded angle by using the static friction between the end of the fixing piece 132 and the second limiting groove 322, so as to prevent the support frame 3 from moving, which can effectively prevent the support frame 3 from suddenly unfolding unnecessarily to affect the flight of the unmanned aerial vehicle when flying.

[0081] Further, when the unmanned aerial vehicle lands, the contact impact force of the grounding part 33 of the support frame 3 with the ground is relatively large due to the influence of gravity, so the grounding part 33 is designed to be a flat shape with a wide surface, which can effectively disperse the impact force, and in the embodiment, the grounding part 33 is in the shape of a snowshoe to improve the service life of the support frame 3.

[0082] Further, since the first contact with the ground when the UAV lands is the front end of the grounding portion 33, and then the entire grounding portion 33 slowly falls on the landing surface. Therefore, the front end of the grounding portion 33 is surrounded by a protective end 331. The protective end 331 can prevent excessive dust from flowing into the grounding portion 33 when the grounding portion 33 contacts the ground, and the large area of the protective end 331 can also effectively disperse the impact force on the front end of the grounding portion 33 when landing, thereby effectively preventing excessive wear of the front end of the grounding portion 33.

[0083] Further, as shown in FIG. 8, the support frames 3 on both sides gradually narrow from the front end to the rear end of the foot stand main body 1 in the top view. It should be understood that, by using the principle of triangular stability, such design can make the UAV more stable when landing on the ground.

[0084] In addition, a UAV, a UAV main body, and a UAV height-increasing foot stand detachably connected to the UAV main body are also provided.

[0085] It should be noted that the detachable connection includes the assembly connection of the UAV main body and the UAV height-increasing foot stand by the cooperation of the first buckle member 112 and the second buckle member 2 as described above; the detachable connection also includes other screw connections of the UAV main body and the height-increasing foot stand, etc., as long as it is convenient and fast to connect the UAV height-increasing foot stand and the UAV main body. Moreover, the UAV with the height-increasing foot stand adopting the technical solution can not only increase the contact distance between the UAV body and the landing surface, but also can be unfolded or folded according to the use needs, so as to enrich the use scenarios of the UAV.

[0086] According to the disclosure and teaching of the above description, those skilled in the art of the present application can also make changes and modifications to the above embodiments. Therefore, the present application is not limited to the specific embodiments disclosed and described above, and some modifications and changes of the present application should also fall within the protection scope of the claims of the present application. In addition, although some specific terms are used in the present specification, these terms are only for convenience of explanation and do not constitute any limitation on the present application.
