Description

Technical FieldThe utility model relates to a technical field of UAV, and more particularly relates to a bionic grapple for assisting UAV landing.Background TechnologyIn recent years, UAVs have been widely used in environmental surveillance and wild animal research, but landing in complex environments such as forests is still a challenge. Conventional UAVs rely on flat surfaces to land. However, they are unable to land safely in environments such as irregular branches. This not only limits the life of UAVs, but also reduces their utility in ecological research.Therefore, it is urgent to develop a method that can improve the landing stability of UAVs in complex forest environments, extend observation time, decrease energy consumption, and reduce wild animal impairment.Content of the Utility ModelThe invention aims to solve the technical problems existing in the prior art. The utility model provides a bionic gripper that assists in landing UAVs, inspiring from the bird's claw toe structure to allow UAV to remain stable on irregular surfaces such as branches. This device can reduce energy consumption and allow UAVs to sit on branches as birds, thereby increasing monitoring time and simultaneously reducing environmental impairment.A bionic grapple for supporting UAV landing, comprising a base for connecting to a UAV. The upper end of the base is provided with a support column. The support column is rotatably connected to a bionic hook claw away from an end of the base. The hook claw is rotatably connected to a first connecting rod.At the central position of the top of the base, a drive is provided. The drive is provided with an output shaft. The output shaft end is fixedly connected to the second connecting rod. The first connecting rod away from the hook claw at one end and the second connecting rod away from the driver is rotatably connected.In addition, the drive takes over a servomotor.Moreover, the support column is perpendicular to the base. The end of the support column remote from the base is arcuate. The hook claw is arc-shaped and its both ends are also arc-shaped. One end of the hook claw is connected to one end of the support column in a cocentre-rotatable manner. The radius of the arcuate end of the hook claw is smaller than the radius of the arcuate end of the support column.The utility model has the following advantageous effects as compared with the prior art: the utility model has a reasonable structure, can improve the landing stability of the UAV in a complex forest environment, can increase observation time, can decrease energy consumption, and can reduce wild animal impairment.The utility model improves the durability of the UAV, and the UAV may remain east rather than hovering, thereby reducing power consumption.The utility model increases stability, contributes to reducing wind or other environmental influences, and improves the accuracy of data acquisition.The utility model reduces ecological effects and reduces the impairment of wild animals by drone noise, particularly suitable for bird protection research.Description with DrawingsFIG. 1 is a schematic illustration of a bionic gripper for supporting the UAV landing of the utility model.As shown in the figure: 1. base, 2. support column, 3. hook claw, 4. first connecting rod, 5. drive, 6. second connecting rod.The specific embodimentHereinafter, the bionic hand for supporting UAV landing will be described as an example.As shown in Fig. 1, a bionic gripper for supporting UAV landing comprises a base 1 for connecting to the UAV. The upper end of the base 1 is provided with a support column 2. The support column 2 is rotatably connected to a bionic hook claw 3 away from an end of the base 1. The hook claw 3 is rotatably connected to a first connecting rod 4.At the central position of the upper surface of the base 1, a drive 5 is provided. The drive 5 is provided with an output shaft. The output shaft end is fixedly connected to the second connecting rod 6. The first connecting rod 4 away from the hook claw 3 at one end and the second connecting rod 6 away from the driver 5 is rotatably connected.The drive 5 takes over a servomotor.The support column 2 is perpendicular to the base 1. The hook claw 3 is arc-shaped and its both ends are also arc-shaped. One end of the hook claw 3 is connected to one end of the support column 2 in a cocentre-rotatable manner. The radius of the arcuate end of the hook claw 3 is smaller than the radius of the arcuate end of the support column 2.The radius of an end of the arcuate hook claw 3 is smaller than the radius of an end of the arcuate support column 2, which is conducive to the cooperation of the support column 2 and the hook claw 3 in order to together realize the gripping stability of the aste.The utility model discloses an application in landing the UAV in forest. Two feet, i.e. two structures of the utility model, are arranged on the underside of the UAV. When the UAV flies over a branch and floats, the servo motor starts. The hook claw 3 rotates through the first connecting rod 4, the second connecting rod 6, and the hook claw 3 and the arc end of the support column 2 cooperate to grasp and fix the branch. After the branch is firmly gripped, it may happen that the rotor fails from the UAV.The utility model is a bionic design that imitates the bird's claw tip structure, the hook claw 3 resembles the front lateral claw tip of the bird's claw, and the arcuate end of the support pillar 2 resembles the rear claw tip of the bird's claw, so that it can land on a branch and hang stably.The utility model discloses stable landing: improvement of landing ability of UAV in complex environment (e.g., forest), increase of observation stability.The utility model and its embodiments have been described above. This description is not limiting. What is illustrated in the drawings is only one embodiment of the utility model, and the actual structure is not limited thereto. In short, if one of ordinary skill in the art can inspire therefrom and, without departing from the curative purpose of the utility model, can design a similar structural method and embodiment to the technical solution without curativeness, they all fall within the protection of the utility model.
