Description

Technical Field

[0001] This invention relates to unmanned aerial vehicle (UAV) storage and transportation devices, and more specifically to a UAV storage and transportation mechanism that enables rapid loading. Background Technology

[0002] A vehicle-mounted unmanned aerial vehicle (UAV) system is a device capable of mounting and controlling UAVs on a moving vehicle. This system is typically designed for rapid deployment and operation of UAVs to support various missions, including reconnaissance, surveillance, search and rescue, etc. The main components of such a system include a loading vehicle, a UAV storage and transportation mechanism, storage containers, and a pitch mechanism. The storage containers store the UAVs to be loaded, the UAV storage and transportation mechanism contains a loading unit for mounting the storage containers, and the pitch mechanism works in conjunction with the UAV storage and transportation mechanism to adjust the pitch angle of the UAVs.

[0003] A commonly used storage and transportation cylinder has a length of 1.2–1.4 m, a diameter of 150–200 mm, with the diameter at both ends being larger than that in the middle, and weighs 9 kg. Due to its large size and weight, the loading and unloading of this storage and transportation cylinder in existing UAV storage and transportation mechanisms requires multiple people and tools. Furthermore, the length or diameter tolerance of the same batch of this storage and transportation cylinder is approximately ±2 mm, causing it to shake and make noise during storage and transportation after being installed in the loading unit of the UAV storage and transportation mechanism. Summary of the Invention

[0004] The purpose of this invention is to address the shortcomings of existing drone storage and transportation mechanisms, such as the inability of a single person to fill and disassemble the storage and transportation cylinders without tools due to their large size and weight, and the inability of the filling unit of existing drone storage and transportation mechanisms to accurately limit the position of the storage and transportation cylinders due to the large tolerance of the same batch of storage and transportation cylinders. The invention provides a drone storage and transportation mechanism that can achieve rapid filling.

[0005] To address the shortcomings of the existing technology, the present invention provides the following technical solution:

[0006] A drone storage and transportation mechanism that enables rapid loading is characterized by including at least one loading unit;

[0007] Each loading unit includes, from top to bottom, a locking assembly, a first support guide assembly, a panel, a front end cap, a second support guide assembly, a rear end cap, an end cap base, and a back plate;

[0008] The panel is provided with mounting holes adapted to the storage and transportation cylinder to be filled. The first support and guide assembly includes a support column disposed on the outer periphery of the mounting hole. The upper end of the support column is provided with the locking assembly, which includes a locking tongue for radially limiting the storage and transportation cylinder to be filled. The second support and guide assembly includes a plurality of guide columns evenly distributed on the outer periphery of the mounting hole. The front end of each guide column is connected to the front end cap, and the rear end is connected to the rear end cap. The axial cross-section of the plurality of guide columns is tangent to the inner ring of the rear end cap and the inner ring of the front end cap.

[0009] The lower end of the rear end cap is provided with an axial protruding ring, which extends into the inner hole of the end cap base and is fixed to the end cap base. The lower end of the end cap base is fixed to the back plate, and a radial protruding ring is provided on the inner ring of the lower end. A compression sleeve, an anti-collision pad, and a compression spring are arranged sequentially from top to bottom between the bottom surface of the axial protruding ring and the top surface of the radial protruding ring. The bottom surface of the anti-collision pad and the top surface of the radial protruding ring are respectively provided with grooves that fit the upper and lower ends of the compression spring. Multiple circumferentially distributed radial through holes are provided on the side wall of the rear end cap. A plunger is provided in each radial through hole, and a spring is provided in the plunger. The plunger is used to eliminate the radial clearance of the storage and transportation cylinder to be filled and prevent shaking.

[0010] Furthermore, the locking assembly includes a latch seat, a spring plate, a latch, a latch rod, and a latch spring. The latch seat is located at the upper end of the support column, and the spring plate is mounted on the latch seat. The latch is mounted on the latch seat and can slide along the latch seat. One end of the latch rod is provided with a handle, and the other end passes radially through a locking hole provided on the spring plate along the storage and transportation cylinder to be filled and connects to the latch. The end of the handle near the spring plate is provided with a locking element. When the handle is rotated to a preset angle, the locking element can pass through the locking hole. The latch spring is fitted on the latch rod, and its two ends abut against the spring plate and the latch, respectively. By rotating the handle, the locking element engages with the spring plate, the latch rod stretches the latch, and the latch spring is compressed, thereby retracting the latch and ensuring that the storage and transportation cylinder can be smoothly inserted and removed radially. By rotating the handle to a preset angle, the locking element passes through the locking hole, the latch spring is released, and the latch can achieve radial locking of the storage and transportation cylinder under the action of the latch spring.

[0011] Furthermore, the first support and guide assembly also includes a limiting guide post arranged along the axial direction of the storage and transportation cylinder to be filled. The limiting guide post is arranged on the top surface of the panel and is symmetrically arranged around the mounting hole with the support post.

[0012] Furthermore, the lower end of the support column is threadedly connected to the panel via a threaded pad, and the upper end is threadedly connected to the lock tongue seat via a fixed back plate.

[0013] Furthermore, the anti-collision pad includes two symmetrically arranged semicircles. The anti-collision pad can only move up and down, and will not generate torque if it does not move around the circumference.

[0014] Furthermore, it includes multiple filling units, multiple panels interconnected to form a whole, and multiple back plates interconnected to form a whole.

[0015] Compared with the prior art, the beneficial effects of the present invention are:

[0016] (1) The present invention provides a UAV storage and transportation mechanism that enables rapid filling, comprising at least one filling unit. Each filling unit includes a locking component, a first support and guide component, a panel, a front end cap, a second support and guide component, a rear end cap, an end cap base, and a back plate. The present invention can provide axial preload and radial preload to the storage cylinder, eliminate axial and radial gaps, and prevent shaking and noise during storage and transportation. Furthermore, the present invention adopts an integrated structure and uses the first support and guide component and the second support and guide component to ensure smooth and uninterrupted loading of the storage and transportation cylinder. It can be operated by a single person without tools, thereby improving filling efficiency.

[0017] (2) The present invention provides a UAV storage and transportation mechanism that enables rapid filling. It uses anti-collision pads and compression springs to achieve pre-tightening force in the axial direction of the storage and transportation cylinder, uses plungers to eliminate radial clearance of the storage and transportation cylinder, and uses locking components that meet the requirements of UAV storage and transportation and the requirements of the storage and transportation cylinder shell to radially limit the outer circumference of the storage and transportation cylinder within a range of less than or equal to 10mm, ensuring that the storage and transportation cylinder will not shake or make noise during the storage and transportation process after being installed in the filling unit.
