Description

Technical Field

[0001] The utility model relates to the technical field of unmanned aerial vehicles, in particular to an auxiliary take-off device for unmanned aerial vehicles. Background Art

[0002] In the early stage of drone takeoff, due to its slow flight speed, its ability to resist external interference is relatively weak, especially when encountering severe weather conditions such as strong winds, which will affect the stability of the drone and cause it to deviate from the planned flight path. In serious cases, it may cause the drone to lose control, suffer structural damage or even crash.

[0003] In the prior art, operations are mainly performed in areas with lower wind speeds to reduce the impact of the external environment on flight stability, but this is greatly affected by the site; or the drone is manually thrown into the air to give it a higher initial speed, but this method is only suitable for drones that can automatically correct their flight attitude in the air, and has high requirements on the performance of the drone itself. Therefore, the present application provides a drone auxiliary take-off device. Utility Model Content

[0004] In order to solve the above-mentioned deficiencies in the prior art, the purpose of the utility model is to provide a drone auxiliary take-off device, which can reduce the wind impact from a specific direction, provide a stable and controllable take-off environment for the drone, and has a high safety factor.

[0005] The technical solution adopted by the utility model to solve its technical problems is:

[0006] Provided is a drone auxiliary take-off device, comprising an extension arm, a steering seat and a drone placement plate; the end of the extension arm is rotatably mounted with the steering seat, and the drone placement plate is rotatably mounted on the steering seat; a windshield is fixedly mounted on the upper end of the side of the drone placement plate, and L-shaped elastic clamp arms are detachably connected to both sides of the top of the drone placement plate.

[0007] Furthermore, an articulated seat is provided at the end of the extension arm, and the direction-adjusting seat is rotatably connected to the articulated seat.

[0008] Furthermore, a magnetic column and an adsorption handle are provided on the adjustment seat, and a magnetic sheet and an embedding groove are provided on both sides of the hinged seat respectively.

[0011] Furthermore, a motor for driving the drone placement plate to rotate is installed in the direction adjustment seat.

[0012] Compared with the prior art, the beneficial effects of the utility model are:

[0013] 1. The drone auxiliary take-off device of the utility model example adjusts the distance between the two L-shaped elastic clamp arms so that the two L-shaped elastic clamp arms clamp and limit the drone legs. After the propeller speed increases, the drone legs are separated from the two L-shaped elastic clamp arms, so that the drone takes off smoothly after having a certain initial speed. In this process, the wind shield is used to block the direction of the wind, weaken the wind impact from a specific direction, and provide a stable and controllable take-off environment for the drone. In addition, since the extension arm has a certain length, a safe distance between the drone and the user can be maintained.

[0014] 2. In the drone auxiliary take-off device of the utility model example, a pressure sensor is installed between the wind shield and the wind detection plate; when the wind blows towards the wind detection plate, pressure is applied to the wind detection plate, at which time the pressure sensor is triggered to detect the wind direction, and the device has a good automated use effect.
