Description

TECHNICAL FIELD

[0001] The utility model relates to a coaxial double-paddle unmanned plane, in particular to a coaxial double-paddle unmanned plane with elastic buffer support. BACKGROUND

[0002] The coaxial double-paddle unmanned plane is connected with two rotors through a shaft, and the counter torques generated by the two rotors are offset in the state of reverse rotation at the same time, so that the stable operation of the helicopter is ensured.

[0003] However, the coaxial double-paddle unmanned plane in the prior art is directly landed on the ground, but the collision and the counter shock caused when the unmanned plane contacts the ground will cause damage to the unmanned plane and greatly affect the service life of the unmanned plane. Therefore, the coaxial double-paddle unmanned plane with elastic buffer support is provided. UTILITY MODEL CONTENT

[0004] The utility model discloses a coaxial double-paddle unmanned plane with elastic buffer support.

[0005] In order to achieve the above purpose, the utility model provides the following technical scheme: a coaxial double-paddle unmanned plane with elastic buffer support, which comprises an unmanned plane body, a rotor one and a rotor two installed on the unmanned plane body, and a support with elastic buffer function installed on the lower part of the fuselage.

[0006] Further preferably, the coaxial double-paddle unmanned plane with elastic buffer support further comprises a limiting sliding rod arranged on the limiting block and slidably connected with the sliding groove, which limits the position of the support rod and has a limiting and guiding effect.

[0007] Further preferably, the coaxial double-paddle unmanned plane with elastic buffer support further comprises a supporting block installed on the other end of the support rod.

[0008] Further preferably, the coaxial double-paddle unmanned plane with elastic buffer support further comprises a supporting pad movably installed on the supporting block, a spherical connecting piece arranged on the supporting pad, and a fixing piece for movably installing the spherical connecting piece on the supporting block.

[0009] Further preferably, the coaxial double-paddle unmanned plane with elastic buffer support further comprises a flexible pad installed on the bottom of the supporting pad.

[0010] The beneficial effects of this utility model are as follows: By setting an elastic contraction structure, the support rod can be contracted on the connecting rod. At the same time, by setting a spring between the connecting rod and the support rod, the support rod can be elastically contracted, thereby providing a cushioning effect when the drone lands, reducing the reaction force on the drone upon landing, and improving the service life of the drone. In addition, the design of several telescopic support rods allows the support rods to be contracted at the appropriate positions according to the terrain when the drone lands, thereby preventing the drone from tipping over and being damaged due to uneven terrain upon landing.

[0016] The following description, in conjunction with the accompanying drawings, further illustrates a coaxial dual-propeller unmanned aerial vehicle (UAV) with an elastic buffer support according to this utility model.

[0017] It should be noted that all directional indicators such as up, down, left, right, front, back, etc. in the embodiments of this utility model are only used to explain the relative positional relationship and movement of the components in a specific posture as shown in the attached figure. If the specific posture changes, the directional indicator will also change accordingly.

[0018] In this utility model, unless otherwise explicitly specified and limited, the terms "connection," "fixing," etc., should be interpreted broadly; for example, "fixing" can mean a fixed connection, a detachable connection, or an integral part; it can also mean a mechanical connection, unless otherwise explicitly limited. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0019] See Figures 1-4As shown, a coaxial dual-propeller unmanned aerial vehicle (UAV) with an elastic buffer support includes a UAV body 1 and rotor 2 and rotor 3 mounted on the UAV body 1; it is characterized by further including a support 4 with elastic buffer function mounted on the lower part of the fuselage; the support 4 includes a plurality of connecting rods 41 fixedly connected to the UAV body 1, a support rod 42 movably connected to the connecting rods 41, and an elastic retraction structure disposed between the connecting rods 41 and the support rod 42 to allow the support rod 42 to retract elastically; the elastic retraction structure includes a spring 5 disposed in the connecting rod 41, a sliding groove 51 disposed on the connecting rod 41, and a limiting block 52 installed at the end of the support rod 42.

[0020] By setting up an elastic contraction structure, the support rod 42 can be contracted on the connecting rod 41. At the same time, by setting a spring 5 between the connecting rod 41 and the support rod 42, the support rod 42 can be elastically contracted, thereby providing a cushioning effect when the drone lands, reducing the reaction force experienced by the drone upon landing. In addition, the telescopic design of the support rod 42 allows the drone to contract accordingly based on the terrain upon landing, thereby preventing the drone from tipping over and being damaged due to uneven terrain.

[0021] In one embodiment, a limiting sliding rod 53 is provided on the limiting block 52 and slidably connected to the sliding groove 51 to limit and guide the position of the support rod 42.

[0022] The sliding groove 51 and the limiting sliding rod 53 limit and guide the movement of the support rod 42 within the connecting rod 41, and also limit the support rod 42 within the connecting rod 41 to prevent the support rod 42 from detaching from the connecting rod 41. The limiting block 52 is threaded onto one end of the support rod 42, and the limiting sliding rod 53 is threaded onto the limiting block 52.

[0023] In one embodiment, the device further includes a support block 6 installed at the other end of the support rod 42; it also includes a support pad 61 movably installed on the support block 6, a spherical connector 62 disposed on the support pad 61, and a fixing member 63 for movably installing the spherical connector 62 on the support block 6; the spherical connector 62 allows the support pad 61 to be rotatably installed on the support block 6, so that the support pad 61 can be adjusted according to the flatness of the ground when in contact with the ground, thereby enabling the support pad 61 to be more stably supported on the ground, thereby improving the stability of the drone after landing.

[0024] In one embodiment, a flexible pad 64 is also installed at the bottom of the support pad 61, which further improves the cushioning effect of the drone after landing.

[0025] The scope of protection of this utility model is not limited to the above embodiments and their variations. Conventional modifications and substitutions made by those skilled in the art based on the content of these embodiments are all within the scope of protection of this utility model.
