Abstract
Description
Technical Field
[0001] This application relates to the field of unmanned aerial vehicle (UAV) technology, and in particular to a retractable tray device for transporting logistics boxes by UAVs. Background Technology
[0002] In recent years, with the continuous pressure from e-commerce, cold chain, and emergency medical scenarios on the delivery time, coverage radius, and labor costs of the "last 100 meters" and even the "last mile" of delivery, drone freight has become an industry-recognized important solution. However, existing technologies generally have the following pain points: 1) The diverse sizes of logistics boxes do not match the payload space of drones. Traditional fixed brackets can only accommodate single-size boxes, resulting in low drone loading efficiency and high return empty load rate; 2) Insufficient on-site rapid deployment capability. Fixed brackets are large and non-foldable, making it difficult to quickly deploy and retrieve them in confined spaces such as the field, rooftops, and ship decks, and they occupy additional cargo space during transportation; 3) Limited box positioning and anti-collision methods. Relying solely on ropes or simple baffles for positioning, the boxes are prone to sliding and collisions due to airflow disturbances or sudden stops and starts during transportation, causing damage to the boxes and internal cargo; 4) Poor universality of lifting interfaces. Different drone brands have significant differences in hook size and form, and existing brackets often require additional adapters, increasing operational steps and the risk of failure; 5) Positioning and energy replenishment capabilities. If the drone loses contact en route, ground personnel cannot monitor the container's location in real time; at the same time, when left idle outdoors for an extended period, the positioning tag's battery will run out, leading to a "black box" phenomenon.
[0003] Therefore, based on the above problems, there is an urgent need to develop a retractable tray device for transporting logistics boxes by drones. Utility Model Content

Thus, a feature defined with "first," "second," "third," and "fourth" may explicitly or implicitly include one or more of that feature.
[0032] Combination Figure 1 As shown in the figure, this application discloses a retractable tray device for transporting logistics boxes by drones. The retractable tray device includes a tray 1 that can be retracted and extended along the length and width of the drone transport logistics box 5, an anti-collision positioning seat 2 disposed at the end of the tray 1 for positioning the drone transport logistics box 5, a lifting device 3 disposed on the side wall of the anti-collision positioning seat 2 for easy drone hoisting, a wireless positioning device disposed on the anti-collision positioning seat 2, and a solar panel 4 electrically connected to the wireless positioning device.
[0033] The retractable bracket device designed in the above manner can not only be compatible with various container sizes, but also facilitate the convenient and quick retraction and unfolding of the bracket 1. At the same time, it can also install the anti-collision positioning seat 2 at the end of the bracket 1, as well as accessories such as the wireless positioning device, solar panel 4, and hoisting device 3 set on the anti-collision positioning seat 2, which expands the functions and increases the ease of use. Moreover, if the drone loses contact during the journey, ground personnel can also monitor the position of the container in real time.
[0034] More specifically, in combination Figure 2 As shown, preferably, the bracket 1 includes a first telescopic member 11 and a second telescopic member 12 spaced apart, and a first connecting rod 13 and a second connecting rod 14 pivotally connected between the first telescopic member 11 and the second telescopic member 12. The first connecting rod 13 and the second connecting rod 14 are arranged in a cross configuration, and the middle parts of the first connecting rod 13 and the second connecting rod 14 are hinged to each other. The two ends of the first connecting rod 13 and the second connecting rod 14 are respectively pivotally connected to the corresponding first telescopic member 11 and the second telescopic member 12.
[0035] To further accommodate the expansion and contraction of the bracket 1 along the width and length of the drone transport logistics box 5, and thus better suit different sizes of drone transport logistics boxes 5, preferably, the first telescopic member 11 and the second telescopic member 12, configured as described above, have identical structures, and both the first telescopic member 11 and the second telescopic member 12 are as follows: Figure 4 As shown, a first telescopic part 111 and a second telescopic part 112 are provided, and the first telescopic part 111 and the second telescopic part 112 slide together along the length direction.
[0036] Specifically, the first telescopic part 111 and the second telescopic part 112 are provided with a first sliding groove 113, and the second telescopic parts 112 on both sides of the first sliding groove 113 are respectively provided with a second sliding groove 1121 and a third sliding groove 1122 along the length direction; the pivot shafts of one pivot end of the first connecting rod 13 and the second connecting rod 14 are respectively slidably engaged with the corresponding first sliding groove 113; the first telescopic part 111 is provided with a guide post 1111 that engages with the corresponding second sliding groove 1121 and third sliding groove 1122.
[0037] The bracket 1 with the above-mentioned structural design has the first telescopic member 11 and the second telescopic member 12 connected as one unit by the first connecting rod 13 and the second connecting rod 14 which are arranged in a cross manner. When the bracket 1 is retracted or extended, the end hinge shafts of the first connecting rod 13 and the second connecting rod 14 on the same side will slide along the first sliding groove 113 opened on the first telescopic part 111 and the second telescopic part 112 respectively, thereby realizing the adjustment of the first telescopic member 11 and the second telescopic member 12 along the width direction of the UAV transport logistics box 5.
[0038] When it is necessary to adjust the bracket 1 along the length of the drone transport logistics box 5, since the end of the first telescopic part 111 is provided with a guide post 1111 that cooperates with the second slide groove 1121 and the third slide groove 1122 on the second telescopic part 112, the telescopic length can be adjusted by pushing and pulling the first telescopic part 111 and the second telescopic part 112.
[0039] The bracket 1, designed in the above manner, can conveniently and flexibly accommodate various sizes of drone transport logistics boxes 5, thereby providing greater convenience and practicality for drone transportation.
[0040] Furthermore, to facilitate the positioning and loading of the drone transport logistics box 5, preferably, anti-collision positioning seats 2 are also installed at both ends of the first telescopic member 11 and the second telescopic member 12, respectively. These anti-collision positioning seats 2 are as follows: Figure 5As shown, it includes a base 21 and an L-shaped positioning wall 22 extending upward along the height direction of adjacent side walls of the base 21. During installation, the base 21 can be connected to the ends of the first telescopic member 11 and the second telescopic member 12 by screws or pivot shafts. Then, the bracket 1 is adjusted to match the drone transport logistics box 5, and the drone transport logistics box 5 is placed on the base 21 and positioned by the L-shaped positioning wall 22. In this way, the corners of the drone transport logistics box 5 can also be protected by the L-shaped positioning wall 22.
[0041] To facilitate quick and easy connection with the hook of the drone, eliminating the many hassles associated with rope fixation in related technologies, lifting rings are also provided on one side wall of each of the multiple anti-collision positioning bases 21. This not only enhances the versatility of lifting but also effectively improves the efficiency of lifting connection.
[0042] Furthermore, to prevent risks such as the loss of the drone transport logistics box 5 due to drone disconnection, preferably, at least one of the multiple anti-collision positioning seats 2 is equipped with a wireless positioning device and a solar panel 4. This way, the solar panel 4 provides power to the wireless positioning device, ensuring that the drone transport logistics box 5 can still be detected promptly even when the drone is disconnected. The specific circuit connection and working principle between the wireless positioning device and the solar panel 4 are commonly used in related technologies and will not be elaborated upon here.
[0043] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
