Abstract
Description
Technical Field
[0001] This utility model relates to the field of aircraft mechanism design, and in particular to a cargo drone launching device. Background Technology
[0002] With the rapid iteration of drone technology, the application scenarios of cargo drones are constantly expanding into multiple fields, from last-mile delivery in cities and emergency medical supply transfer to material transportation in special environments. For example, after natural disasters such as earthquakes and floods, ground transportation is often paralyzed, and cargo drones can use their flexible flight capabilities to accurately deliver supplies such as food, medicine, and rescue tools to stranded areas; in plateau regions, many outposts are located in remote areas with complex road conditions, and drones can efficiently complete the transportation of supplies such as fuel and living supplies; in the face of forest fires, drones can quickly carry fire extinguishing bombs, water bags, and other equipment to the fire scene to achieve precise delivery to control the spread of the fire.
[0003] However, in the actual operation of cargo drones, there are still many problems to be solved in cargo delivery and reception technologies. Some existing delivery mechanisms have significant shortcomings in terms of practicality and cost-effectiveness. On the one hand, many delivery structures require specially designed cargo containers to function properly, meaning users must invest additional costs in customizing these containers. This not only increases operating expenses but also greatly limits the applicability of the drone—these mechanisms are often unable to handle non-standard sized or shaped cargo. On the other hand, some mechanisms have flaws in their force transmission design, causing the servo motors to continuously bear large loads throughout the operation. As the core component of the drone delivery mechanism, the servo motors, under prolonged high loads, will experience significantly accelerated wear and tear, shortening their lifespan and increasing the frequency and cost of equipment maintenance. In severe cases, servo motor malfunctions may even lead to cargo delivery failures, causing unnecessary losses.
[0004] Therefore, there is an urgent need to provide a solution for a cargo drone delivery device. Utility Model Content
[0005] To address the above problems, this utility model provides a cargo drone launching device with a large load capacity and convenient use, which is particularly suitable for transporting multi-rotor drones.

[0029] Multiple, including two or more.
[0030] And / or, it should be understood that, for the purposes of this disclosure, the term "and / or" is merely a description of the relationship between related objects, indicating that three relationships can exist. For example, A and / or B can represent: A existing alone, A and B existing simultaneously, and B existing alone.
[0031] One embodiment of the present invention provides a cargo drone launching device, comprising: a support frame 1, a cargo support plate 2, a servo motor assembly, a linkage mechanism, a slide 8, and a slide bar 9.
[0032] like Figure 1 As shown, the servo assembly is connected to the support frame 1; the slide rod 9 is slidably disposed in the slide groove 8; one end of the linkage mechanism is connected to the servo assembly and the other end is connected to the slide rod 9. The servo assembly is used to provide power and, after passing through the linkage mechanism, can drive the slide rod 9 to slide in the slide groove 8; the cargo support plate 2 is connected to the slide rod 9, and the sliding of the slide rod 9 can drive the cargo support plate 2 to move.
[0033] This utility model has a compact overall structure and can withstand a large cargo box load; it can be used in conjunction with the body structure to limit and support cargo, and the cargo support plate 2 does not require a specially made cargo box; it has low power consumption during use, and only requires power to the servo motor 4 when the cargo box is airdropped and released; the servo motor 4 will not be subjected to force during the static load-bearing process, and the servo motor 4 has a long service life and high reliability.
[0034] Specifically, the linkage mechanism includes a crank 5, a rocker arm 6, and a connecting rod 7 that are hinged in sequence. The servo assembly can drive the crank 5 to move, so that the rocker arm 6 and the connecting rod 7 are linked together.
[0035] Furthermore, the end of the slide rod 9 has a connecting portion, which is connected to the connecting rod 7. Even further, the connection between the connecting portion and the connecting rod 7 is hinged. That is, the connecting rod 7 and the connecting portion can rotate along the connection point. In one specific embodiment, the end of the connecting rod 7 connected to the connecting portion is a plate-like structure with a connecting rod connecting hole in the middle. The connecting portion consists of two parallel plate-like structures with a slide rod connecting hole in the middle. The plate-like structure of the connecting rod 7 can be placed between the two plate-like structures of the connecting portion, aligning the connecting rod connecting hole and the slide rod connecting hole, and then locked in place with bolts, thus hinged the connecting portion to the connecting rod 7. Of course, the hinge structure can also be in other forms, such as a gear-like structure or a hinge structure, which will not be elaborated here.
[0036] In this preferred embodiment, the slide bar 9 is horizontally positioned and slides in the horizontal direction, and the cargo support plate 2 is connected to the upper surface of the slide bar 9. Therefore, the slide bar 9 drives the cargo support plate 2 to move in the horizontal direction.
[0037] Furthermore, the slide rod 9 is also provided with a limiting part, which is located near the connecting part. Therefore, after the slide rod 9 is connected to the connecting rod 7, the limiting part is located outside the slide groove 8 on the side where the slide rod 9 is connected to the connecting rod 7. The limiting part can restrict the sliding of the slide rod 9 and prevent the slide rod 9 from coming out of the slide groove 8.
[0038] Furthermore, the servo assembly includes a servo mount 3 and a servo 4. The servo mount 3 is connected to the support frame 1, and the servo 4 is mounted on the servo mount 3.
[0039] Furthermore, the slide 8 is connected to the support frame 1. Therefore, the position of the slide 8 can be fixed and will not move as the slide rod 9 slides. The slide 8 can be a separate tubular structure for the slide rod 9 to slide, or it can include a tubular structure for the slide rod 9 to slide and a fixing part, which is connected to the support frame 1. The fixing part increases the space between the slide 8 and the support frame 1, thereby increasing the space above the cargo support plate 2, thus not affecting the placement of large goods on the cargo support plate 2. Specifically, the fixing part is vertically positioned above the slide 8 and connected to the bottom of the support frame 1.
[0040] Furthermore, the support frame 1 has a mounting section for connection with the drone. The mounting section is connected to the drone by bolts.
[0041] The unloading and receiving process of the cargo drone throwing device provided by this utility model is as follows: The servo motor 4 drives the crank 5 to rotate, which drives the connecting rod 7 to move through the rocker arm 6. The connecting rod 7 provides tension so that the slide rod 9 slides in the slide groove 8 and drives the cargo support plate 2 to move, thereby achieving unloading; Conversely, the servo motor 4 works in the opposite direction so that the connecting rod 7 provides thrust, and the slide rod 9 drives the cargo support plate 2 to move, thereby achieving receiving.
[0042] The force analysis of the cargo drone throwing device provided by this utility model is as follows: When transporting cargo, the gravity and inertial force of the cargo are transmitted from the cargo support plate 2 to the slide bar 9, and then the force and torque act on the slide groove 8, and finally are transmitted to the drone body structure through the support frame 1. Since the slide bar 9 and the connecting rod 7 are hinged, the entire force transmission process does not involve the linkage mechanism, and therefore the servo motor 4 is not subjected to force when transporting cargo.
[0043] It should be noted that, in this document, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus. Unless otherwise specified, an element defined by the phrase "comprising one..." does not exclude the presence of other identical elements in the process, method, article, or apparatus that includes that element.
[0044] The sequence numbers of the above embodiments of the present invention are for descriptive purposes only and do not represent the superiority or inferiority of the embodiments.
[0045] Through the above description of the embodiments, those skilled in the art can clearly understand that the above implementation methods can be implemented by means of software plus necessary general-purpose hardware platforms. Of course, they can also be implemented by hardware, but in many cases the former is a better implementation method. Based on this understanding, the technical solution of this utility model, in essence, or the part that contributes to the prior art, can be embodied in the form of a software product. This computer software product is stored in a storage medium (such as ROM / RAM, magnetic disk, optical disk) and includes several instructions to cause a terminal (which may be a mobile phone, computer, server, air conditioner, or network device, etc.) to execute the methods described in the various embodiments of this utility model.
