[0002] The detection equipment of unmanned aerial vehicles in the environmental protection industry usually adopts a structural form in which a pod equipped with detection equipment is hung under the unmanned aerial vehicle. At present, a structural form of directly fastening with bolts or connecting with dovetail grooves is usually adopted to fix the pod under the unmanned aerial vehicle. The defects of this hanging connection form are as follows: (1) The hanging connection structure between the unmanned aerial vehicle and the pod is complex, the connection and disassembly are very inconvenient, and the hanging cost is high; (2) The existing hanging connection structure between the unmanned aerial vehicle and the pod is heavy in weight and large in volume, resulting in a short staying time of the unmanned aerial vehicles in the environmental protection industry in the air and a short sampling and detection period for high-altitude environmental pollution sources, which cannot meet the use requirements; (3) The height after the unmanned aerial vehicle and the pod are connected by the existing hanging connection structure is too high, which has requirements for the flight height of the unmanned aerial vehicle and severely compresses the height that can be detected by the lower pod. Summary of the Utility Model

[0003] The purpose of the utility model is to overcome the above-mentioned defects existing in the prior art, and propose a locking device for hanging and mounting an unmanned aerial vehicle pod, which is light in weight, convenient to assemble, strong in reliability, and can meet the detection requirements.

[0004] The technical solution of the utility model is: a locking device for hanging and mounting an unmanned aerial vehicle pod, which includes:

[0005] A first hanging component for realizing fixed connection with the upper unmanned aerial vehicle;

[0006] A second locking component is arranged on the first hanging component, including a locking block and a spring connected to the locking block. Through the elastic force of the spring, the locking block is used to realize the locking and fixed connection between the second locking component and the lower pod.

[0007] In the utility model, the first hanging component includes:

[0013] The second locking assembly further includes a housing;

[0014] The housing is fixed on the upper surface of the mounting plate, and a strip-shaped cavity is arranged inside it. A groove is provided at the end of the housing facing the locking block, and a partition is provided between the groove and the strip-shaped cavity;

[0015] The locking block is connected to the housing through a guide rod. One end of the locking block is connected to the guide rod, and a hook facing the direction of the drone is provided at the other end of the locking block. In the initial state, the locking block is located in the groove of the housing;

Detailed implementation manners

[0037] In order to make the above objects, features and advantages of the present utility model more obvious and understandable, the following detailed description of the specific implementation manners of the present utility model will be given with reference to the accompanying drawings.

[0038] In the following description, specific details are set forth in order to provide a thorough understanding of the present utility model. However, the present utility model can be implemented in many other ways different from those described herein, and those skilled in the art can make similar generalizations without departing from the connotation of the present utility model. Therefore, the present utility model is not limited by the specific implementation manners disclosed below.

[0039] As Figure 1 and 2 shown in the figure, the unmanned aerial vehicle pod mounting and locking device of the present utility model includes a first hanging component 1 and a second locking component 2. Through the first hanging component 1, the connection between the device and the bottom surface of the unmanned aerial vehicle 3 is realized. The second locking component 2 is arranged on the first hanging component 1, and through the second locking component 2, the locking connection between the device and the lower pod 4 is realized.

[0040] like Figure 3 As shown, the first mounting assembly 1 includes a mounting plate 101, which is in a flat plate shape and is fixedly connected to the bottom plane of the drone by a plurality of bolts. When the device is in a mounting locking state, the top surface of the mounting plate 101 contacts the bottom surface of the drone 3, and the bottom surface of the mounting plate 101 contacts the top surface of the pod 4.

[0041] In the present application, one side of the mounting plate 101 is fixedly connected to the bottom surface of the drone 3, and the other side of the corresponding mounting plate 101 is suspended outside the drone. A second locking assembly 2 is provided on the top surface of one end of the mounting plate 101 suspended outside the drone.

[0042] The pod 4 is slidably connected to the first hanger assembly 1. The bottom surface of the mounting plate 101 and the two sides along the sliding direction of the pod are respectively fixed with mounting baffles 102, and the mounting baffles 102 on both sides are symmetrically arranged. Correspondingly, slide grooves are respectively arranged at the side walls on both sides of the pod 4. When the pod is in a connected state with the first hanger assembly 1, the mounting baffles 102 are respectively arranged in the slide grooves at the side walls on both sides, and the mounting baffles 102 and the slide grooves are slidably connected. When the pod 4 is connected to the first hanger assembly 1, the pod 4 is slid from the bottom of the mounting plate 101 and one end where the second locking assembly is arranged into between the mounting baffles 102 on both sides.

[0043] A bottom stopper 103 is also fixed to the bottom surface of the mounting plate 101, and the bottom stopper 103 is located at the end position of the pod 4 sliding along the bottom surface of the mounting plate. When the pod 4 slides along the bottom surface of the mounting plate, when the pod 4 slides to contact the bottom stopper 103, the bottom stopper 103 limits the pod 4 and prevents the pod 4 from sliding further.

[0044] In this embodiment, the mounting plate 101 is in the shape of a rectangular plate, one end of which along the length direction is suspended outside the drone, and the top surface of the mounting plate at this end is provided with a second locking assembly 2, and a bottom stopper 103 is fixed to the bottom surface of the other end of the corresponding mounting plate 101. Mounting baffles 102 are fixed to the bottom surface of the mounting plate 101 and to both sides of the mounting plate 101 in the width direction.

[0045] like Figure 3 and Figure 4 As shown, the second bracket assembly 2 includes a housing 201 and a locking block 202, and the housing 201 and the locking block 202 are rotatably connected via a guide rod 203. The housing 201 is fixed to the top surface of the mounting plate 101, and the locking block 202 is arranged at one end of the housing 201 away from the drone.

[0046] Inside the housing 201, there is a strip-shaped cavity, and the guide rod 203 is rotatably and slidably arranged in the strip-shaped cavity. The guide rod 203 passes through the side wall of the housing 201 and is fixedly connected to the locking block 202. Therefore, during the rotation of the guide rod 203, the locking block 202 fixedly connected to it is driven to rotate synchronously by a certain angle.

[0047] In this embodiment, the housing 201 is in the shape of a cuboid, and the guide rod 203 is arranged along the length direction of the housing 201. One end of the housing 201 along the length direction is closed, and the other end along the length direction is provided with a groove. When the locking block 202 is arranged vertically, the locking block 202 is exactly located in the groove. A partition 206 is provided between the groove and the strip-shaped cavity, and the partition 206 is connected to the inner wall of the housing.

[0048] The end of the guide rod 203 is connected to the side wall of the partition 206 through a spring 204. The spring 204 is wound around the outer ring of the guide rod 203. In the initial state, the spring 204 is in a compressed state. Under the elastic force of the spring 204, a pulling force towards the housing is applied to the locking block 202 through the guide rod 203, so that the locking block 202 can always be located in the groove. During the rotation of the guide rod, a torsional force is generated in the spring 204, and this torsional force enables the locking block to stay at this position after rotating a certain angle.

[0049] One end of the locking block 202 is fixedly connected to the guide rod 203, and a hook 205 is fixed to the other end of the corresponding locking block 202. The hook is convex and is arranged on the side of the locking block facing the drone. A fixing groove is provided on the side of the pod away from the drone. When the hook at the end of the locking block is located in the fixing groove, the fixed connection between the second locking component and the pod is realized, thereby realizing the fixed connection between the mounting plate and the pod.

[0050] The installation and use process of the device is as follows. First, fix the second locking component 2 on the top surface of the mounting plate 101, and fix the bottom limit block 103 and two symmetrically arranged mounting stoppers 102 at the designated positions on the mounting plate 101. The mounting plate after installation is as Figure 5 shown.

[0051] Then, fix the mounting plate 101 on the bottom surface of the drone 3 through bolts to realize the connection between the device and the drone. When fixing, suspend the mounting plate 101 with the second locking component 2 on the outside of the drone, and the other end of the corresponding mounting plate 101 is fixedly connected to the bottom surface of the drone. The schematic structural diagram of the mounting plate 101 connected to the drone 3 is as Figure 6 shown.

[0052] When installing the pod, first apply a certain external force to pull the locking block 202 out of the groove of the outer shell in the direction away from the drone. At this time, the guide rod 203 fixedly connected to the locking block 202 is also pulled out, and the spring between the guide rod 203 and the partition is compressed. A gap is generated between the end of the locking block 202 and the outer shell 201, as Figure 7 shown.

[0053] Then, apply another certain external force to rotate the guide rod 203 and the locking block 202 connected thereto by a certain angle. In this embodiment, the guide rod 203 and the locking block 202 are rotated by about 90°. At this time, the locking block 202 rotates from the vertical direction to the horizontal direction, as Figure 8 shown.

[0054] Next, remove the pulling force applied to the locking block 202. Under the elastic force of the spring 204, the locking block 202 automatically resets and fits against the side of the outer shell 201 again. At the same time, under the torque of the spring 204, the locking block 202 stays at the position after rotating by a certain angle, as Figure 9 shown.

[0055] Insert the pod 4 between the two mounting stoppers 102 on the bottom surface of the mounting plate. The mounting stoppers 102 are inserted into the sliding grooves on the side wall of the pod 4. Through the sliding connection between the mounting stoppers 102 and the sliding grooves, the pod 4 is gradually pushed below the mounting plate. When the pod is pushed until it contacts the bottom stopper 103, the bottom stopper 103 blocks the pod and stops pushing the pod further, as Figure 10 shown.

[0056] At this time, apply an outward pulling force to the locking block again to make the locking block leave the side of the outer shell; then rotate the guide rod and the locking block to rotate the locking block from the horizontal direction to the vertical direction again. At this time, the hook at the bottom of the locking block is located outside the fixing groove on the side of the pod 4; release the pulling force applied to the locking block. Under the pulling force of the spring, the locking block automatically resets into the groove of the outer shell. During the automatic reset process, the hook 205 on the locking block enters the fixing groove 401 on the side of the pod, and under the elastic force of the spring, the tightening and fixing between the pod and the mounting plate are realized, and then the locking and fixing between the drone and the pod are realized, as Figure 11 shown.

[0057] During the disassembly process of the drone and the pod, similarly pull the locking block 202 to make the hook 205 on the locking block 202 away from the fixing groove 401 on the side of the pod. At this time, the locking and fixing force applied between the drone and the pod is removed. Slide the pod along the mounting stopper 102 and pull it out. After separating the pod from the drone, remove the external force applied to the locking block. Under the elastic force of the spring, the locking block 202 automatically resets, thus realizing the disassembly of the drone and the pod.
