Traditional methods for detecting cargo weight and center of gravity mainly rely on manual measurement and estimation, which suffers from large errors and low efficiency. Some existing solutions include using weighing sensors and tilt sensors for calculation, but these devices are costly and complex to install and use. Therefore, there is an urgent need for a simple, efficient, and accurate fixture for detecting cargo weight and center of gravity. Utility Model Content

[0003] In view of the problems existing in the prior art, the present invention provides a drone cargo loading and balancing tool to improve the problems of large errors and low efficiency in manually measuring and estimating cargo weight and center of gravity.

[0004] To achieve the above and other related objectives, this utility model provides a drone cargo loading and balancing fixture, including a support plate, a carrier, elastic elements, and a detection element. The support plate is configured to place cargo; the carrier is disposed below the support plate; at least four elastic elements are disposed between the support plate and the carrier, connecting the support plate and the carrier; the detection element is configured to determine whether the lowest point of the support plate is lower than a preset threshold.

[0005] In an exemplary embodiment of this application, the support plate includes a support base plate and support side plates. The support base plate is connected to the elastic member; the support side plates are disposed on the side of the support base plate opposite to the elastic member, and the support side plates enclose a space for placing the goods.

[0006] In an exemplary embodiment of this application, the support member includes a support plate and a support side plate. The support plate is connected to the elastic member; the support side plate is fixed to the support plate and extends toward the support plate, and the detection member is fixed to the support side plate.

[0007] In an exemplary embodiment of this application, the detection element includes a detection plate, which is fixed to the top of the supporting side plate.

[0008] In an exemplary embodiment of this application, the detection plate is provided with a through hole, which accommodates the elastic member passing through.

[0009] In an exemplary embodiment of this application, the detection plate is disposed on the top of the bearing side plate and extends to the outer periphery of the bearing side plate, and the projection of the support plate along the direction perpendicular to the support plate coincides with the projection of the detection plate along the direction perpendicular to the support plate.

[0014] In combination with existing technologies, the beneficial effects of this utility model are as follows:

[0015] Cargo weight and center of gravity during loading primarily rely on manual calculation and estimation, which suffers from large errors and low efficiency. Other methods use weighing sensors and tilt sensors for calculation, but these are costly and complex to install and use. This application's drone cargo loading balancing fixture includes a support plate, a load-bearing component, an elastic component, and a detection component. When cargo loading is required, the cargo is placed on the support plate. Under the weight of the cargo, the elastic component is compressed. When the cargo's center of gravity deviates from the expected value, the support plate tilts. The detection component measures whether the lowest point of the support plate is below a preset threshold, thus determining whether the cargo weight or center of gravity meets the drone loading requirements. This application can quickly determine whether the drone-loaded cargo weight or center of gravity meets loading requirements, with high efficiency and low error. Furthermore, the drone cargo loading balancing fixture of this application is low-cost and simple to install and use. Attached Figure Description

[0030] With the rapid development of the logistics industry, drone cargo transportation is gradually becoming an emerging mode of transportation, such as drone delivery of express packages. However, drones have limited carrying capacity and strict requirements regarding the weight and center of gravity of the cargo. If the cargo is too heavy or the center of gravity is off-center, the drone's flight will be unstable, potentially leading to a crash. Currently, weight and center of gravity measurements are mainly determined manually, which is prone to errors, inefficient, and highly dependent on skilled workers.

[0031] In view of this, the present invention provides a drone cargo loading and balancing fixture to quickly determine whether the weight and center of gravity meet the cargo loading requirements, thereby determining whether the drone's flight conditions are met.

[0032] Please see Figures 1 to 4 The drone cargo loading and balancing fixture includes a support plate 100, a load-bearing member 200, an elastic member 300, and a detection member 400. The support plate 100 is used to place cargo 500. The load-bearing member 200 is located below the support plate 100, and the load-bearing plate 210 supports the entire balancing fixture and the cargo 500. At least four elastic members 300 are provided, positioned between the support plate 100 and the load-bearing member 200, and connecting the two. The detection member 400 is configured to detect whether the lowest point of the support plate 100 is below a preset threshold.

[0033] Please see Figure 1 and Figure 3When loading cargo 500, it is placed on support plate 100. Under the weight of cargo 500, elastic element 300 is compressed, causing support plate 100 to descend. By determining the lowest point of support plate 100, the amount of compression of elastic element 300 can be judged, thus directly determining whether the weight of cargo 500 exceeds a threshold. Adjustments to cargo 500 are made based on the current position of support plate 100 to ensure its weight does not exceed the threshold, preventing overloading. When cargo 500 is unevenly loaded on support plate 100, different elastic elements 300 experience different pressures, causing support plate 100 to tilt. By determining whether the lowest point of support plate 100 exceeds a threshold, it can be determined whether the center of gravity of support plate 100 meets loading requirements under the current weight. The position of cargo 500 on support plate 100 or the counterweight is adjusted based on the tilt of support plate 100 to ensure the center of gravity of support plate 100 also meets loading requirements, ensuring safe and stable flight and cargo delivery for the drone.

[0034] The drone cargo loading and balancing fixture of this application can quickly determine whether the weight and center of gravity of the cargo loaded by the drone meet the loading requirements. Compared with manual measurement and estimation, it has the advantages of high efficiency and low error. Moreover, the drone cargo loading and balancing fixture of this application has lower requirements for human skill, avoiding situations where the weight and center of gravity of the cargo cannot be determined in special circumstances. Compared with weighing sensors and tilt sensors, the drone cargo loading and balancing fixture of this application has lower cost, is easy to use, has low environmental requirements, and is suitable for promotion and application by logistics companies, reducing their purchase costs.

[0035] Please see Figure 2 In one embodiment, the support plate 100 includes a support base plate 110 and a support side plate 120.

[0036] The support base plate 110 is connected to the elastic element 300. The support base plate 110 and the elastic element 300 can be fixedly connected, for example, by using screws or other connecting components to fix the elastic element 300 to the support base plate 110. Alternatively, the support base plate 110 can be pressed onto the elastic element 300, and the weight of the support base plate 110 maintains a relatively stable state between the support base plate 110 and the elastic element 300. A groove can also be provided on the support base plate 110, allowing the elastic element 300 to be inserted into the groove for relative fixation between the support base plate 110 and the elastic element 300. This facilitates the use and assembly of the balancing fixture and also makes it easy to replace the elastic element 300.

[0037] Of course, as some alternatives, the support base plate 110 and the elastic element 300 can also achieve a relatively stable connection through other means.

[0038] A support side plate 120 is disposed on the side of the support base plate 110 opposite to the elastic member 300, and the support side plate 120 encloses a space for placing the cargo 500. By enclosing the space with the support side plate 120, the cargo 500 on the support plate 100 can be limited, preventing the cargo 500 from moving when the support plate 100 is tilted, thus effectively ensuring the stability of the loaded cargo 500.

[0039] The support plate 100 can be made of metal, wood, or plastic. The support base plate 110 and the support side plate 120 are fixed relative to each other. The fixing method is selected according to the material. For example, when the support base plate 110 and the support side plate 120 are made of wood, they can be connected by bolts, nails, mortise and tenon joints, etc.; when the support base plate 110 and the support side plate 120 are made of metal, they can be connected by bolts, riveting, welding, etc.; when the support base plate 110 and the support side plate 120 are made of plastic, they can be connected by bolts, heat fusion, etc.; the support base plate 110 and the support side plate 120 can also be integrally formed, etc., as long as the relative fixing of the support base plate 110 and the support side plate 120 is met.

[0040] In one embodiment, the support base plate 110 is a square plate to accommodate the drone's pod. In other embodiments, the support base plate 110 may also be a circular plate, an elliptical plate, or the like.

[0041] In one embodiment, the support plate 100 is detachably connected to the elastic element 300. The support plate 100 is adapted to the drone's loading mechanism, so that after the cargo 500 is loaded, the support plate 100 and the cargo 500 can be loaded together onto the drone, for example, placed in the drone's pod or directly inside the drone's fuselage. This reduces the number of times the cargo 500 needs to be handled, avoids repeated handling of the cargo 500, and improves the drone's loading efficiency.

[0042] Please see Figure 2 In one embodiment, the support member 200 includes a support plate 210 and a support side plate 220.

[0043] The support plate 210 is connected to the elastic element 300. The connection between the support plate 210 and the elastic element 300 can be a fixed connection, such as fixing the elastic element 300 to the support plate 210 with bolts; the connection between the elastic element 300 and the support plate 210 can also be that the elastic element 300 is placed on the support plate 210. Furthermore, the support plate 210 is provided with a groove, and the elastic element 300 is inserted into the groove to facilitate the assembly and disassembly of the balancing fixture, the replacement of the elastic element 300, etc.

[0044] The bearing side plate 220 is fixed to the bearing plate 210 and extends towards the support plate 100. The detection component 400 is fixed to the bearing side plate 220. The bearing side plate 220 provides fixed support for the detection component 400, making the balancing fixture a whole, which facilitates the handling of the balancing fixture, thereby facilitating the use of the balancing fixture and expanding the application scenarios of the balancing fixture.

[0045] The load-bearing component 200 can be made of wood, metal, or plastic, etc. The connection method between the load-bearing side plate 220 and the load-bearing plate 210 depends on the material of the load-bearing component 200. For example, when the load-bearing plate 210 and the load-bearing side plate 220 are made of wood, they can be connected by bolts, nails, mortise and tenon joints, etc. When the load-bearing plate 210 and the load-bearing side plate 220 are made of metal, they can be connected by bolts, riveting, welding, etc. The load-bearing side plate 220 and the load-bearing plate 210 can also be fixed by integral molding or other methods to ensure relative fixation between the load-bearing plate 210 and the load-bearing side plate 220.

[0046] In one embodiment, the support plate 210 is a square plate, such as a rectangular plate or a square plate. In other embodiments, the support plate 210 may also be a circular plate, an elliptical plate, or the like.

[0047] Please see Figure 4 In one embodiment, the detection component 400 includes a detection plate 410, which is fixed to the top of the bearing side plate 220. When the support plate 100 abuts against the detection plate 410, it can be determined that the goods 500 on the support plate 100 are overloaded or that the center of the goods 500 is deviated. The judgment method is simple and clear, and it is convenient to use the balancing tool.

[0048] Please see Figure 4 In one embodiment, the detection plate 410 is provided with a through hole 420, which allows the elastic element 300 to pass through. The through hole 420 does not affect the compression or rebound of the elastic element 300, thus not affecting the operation of the elastic element 300. When the elastic element 300 tilts, the wall of the through hole 420 can also limit the excessive tilting of the elastic element 300, thereby protecting the elastic element 300.

[0049] In one embodiment, the detection plate 410 is disposed on the top of the bearing side plate 220 and extends to the outer periphery of the bearing side plate 220, which can effectively avoid interference between the detection plate 410 and the elastic member 300 and ensure the use of the elastic member 300.

[0050] The outer periphery of the support plate 100 along the direction perpendicular to the support plate 100 coincides with the projection of the detection plate 410 along the direction perpendicular to the support plate 100. The vertical distance between the support plate 100 and the detection plate 410 is small, and the displacement in the horizontal plane when the support plate 100 deflects can be ignored. Therefore, when the support plate 100 descends or deflects, it can interfere with the detection plate 410, and more quickly determine whether the weight or center of gravity of the goods 500 on the support plate 100 meets the loading requirements.

[0051] In another embodiment, the detection element 400 is arranged in a direction perpendicular to the support plate 100, and the detection element 400 is provided with a scale bar. For example, the detection element 400 is in the shape of a vertical rod, and the scale bar is provided on the vertical rod. By observing the height of the lowest point of the support plate 100, it can be determined whether the weight and center of gravity of the goods 500 on the support plate 100 meet the loading requirements.

[0052] Four detection elements 400 are provided, and the four detection elements 400 are respectively disposed on the outer periphery of the support plate 100. The four detection elements 400 can quickly and accurately determine the lowest point height when the support plate 100 is tilted in different directions, and thus quickly and accurately determine whether the weight and center of gravity of the goods 500 on the current support plate 100 meet the loading requirements.

[0053] In one embodiment, the detection element 400 includes a detection plate 410, which is disposed between the support plate 100 and the carrier plate 210. The detection plate 410 is fixed to the carrier plate 210 by a connector, such as a vertical rod, to achieve relative fixation between the detection plate 410 and the carrier plate 210 and ensure that the detection plate 410 is in the expected position to determine whether the weight and center of gravity of the goods 500 on the support plate 100 meet the loading requirements. The outer periphery of the support plate 100 along the direction perpendicular to the support plate 100 coincides with the projection of the detection plate 410 perpendicular to the support plate 100, so that the support plate 100 can interfere with the detection plate 410 when it deflects or descends, and quickly and accurately determine whether the goods 500 on the support plate 100 meet the loading requirements.

[0054] In one embodiment, the elastic element 300 is a spring, which is distributed around the bottom of the support plate 100. The springs are symmetrically arranged at the bottom of the support plate 100 along the centerline of the length direction or the centerline of the width direction of the support plate 100 so that the springs are evenly stressed.

[0055] In one embodiment, the elastic element 300 is a spring, and the springs are arranged in a circumferential array around the bottom of the support plate 100 along its axis. The circumferential array of springs at the bottom of the support plate 100 results in more even force distribution among the springs, thereby allowing for a more accurate determination of whether the center of gravity of the cargo 500 meets the loading requirements.

[0056] This application discloses a drone cargo loading balancing fixture that utilizes the compression degree of the elastic element 300 and the tilt of the support plate 100 to detect the weight and center of gravity of the cargo 500. Compared with traditional manual measurement and estimation methods, this method has smaller errors and higher accuracy. The balancing fixture has a simple structure, is easy to operate, and can quickly detect whether the weight and center of gravity of the cargo 500 meet the requirements, thus improving detection efficiency. This balancing fixture can be made of simple materials such as springs and wooden boards, resulting in low cost and ease of large-scale promotion and application, meeting the needs of logistics companies. Therefore, this utility model effectively overcomes some practical problems in the prior art, thus possessing high utilization value and practical significance.

[0057] The above embodiments are merely illustrative of the principles and effects of this utility model and are not intended to limit the scope of this utility model. Any person skilled in the art can modify or alter the above embodiments without departing from the spirit and scope of this utility model. Therefore, all equivalent modifications or alterations made by those skilled in the art without departing from the spirit and technical concept disclosed in this utility model should still be covered by the claims of this utility model.
