Abstract
Description
Technical Field
[0001] This utility model relates to the field of logistics drone technology, specifically a logistics drone with a detachable cargo compartment. Background Technology
[0002] As an important tool for last-mile delivery, logistics drones have significant advantages in scenarios such as resupplying remote areas and transporting emergency supplies. Their carrying capacity and delivery flexibility directly affect transportation efficiency.
[0003] Currently, most traditional logistics drones adopt a fixed cargo hold design, with the cargo hold rigidly connected to the fuselage or hoisted by steel cables. When the cargo hold is rigidly connected to the fuselage, the drone must return with an empty cargo hold after delivery, which not only increases the ineffective load and consumes extra range, but also limits the amount of goods transported in a single flight. When the cargo hold is hoisted by steel cables, under the influence of external wind and resistance, the center of gravity of the cargo hold is no longer on the same straight line as the center of gravity of the drone. When the center of gravity deviation is large, it affects the balance of the drone's delivery. In view of this, a logistics drone with a detachable cargo hold is proposed. Utility Model Content
[0004] The main objective of this invention is to provide a logistics drone with a detachable cargo compartment, which can solve the problems mentioned in the background section.
[0005] To achieve the above objectives, this utility model proposes a logistics drone with a detachable cargo compartment, comprising a drone body and a cargo compartment. A connecting arm is rotatably connected to the lower side of the drone body, and a mounting plate is bolted to the upper side of the cargo compartment. Connecting components are fixedly connected to the mounting plate, and a limiting mechanism is provided on the mounting plate. The limiting mechanism includes:
[0006] An adjustment assembly, which is connected to a mounting plate;
[0007] An extrusion assembly is connected to an adjustment assembly, and a plug-in assembly is provided above the adjustment assembly.
[0008] Preferably, the adjustment assembly includes a connecting plate, a screw, a nut, and an elastic telescopic rod. The screw is fixed to the connecting plate, threadedly connected to the mounting plate, and threadedly connected to the nut. The two ends of the elastic telescopic rod are fixed to the connecting plate and the mounting plate, respectively. By rotating the nut, the distance between the connecting plate and the mounting plate is adjusted, thereby enabling the limiting mechanism to be used for cargo holds of different sizes.
[0009] Preferably, the compression assembly includes a sleeve, an adjusting telescopic rod, a fixing ring, and a fixing foot. The fixing ring is fixedly connected to the outer wall of the adjusting telescopic rod, and the fixing ring is elastically connected to the inner wall of the sleeve through a return spring. The fixing foot is fixedly connected to the bottom of the adjusting telescopic rod. By adjusting the telescopic rod, the position of the fixing foot can be adjusted, thus adapting to cargo holds of different sizes.
[0010] Preferably, the sleeve is fixedly connected to the lower side of the connecting plate, and the first adjusting telescopic rod passes through the sleeve and the connecting plate, and the first adjusting telescopic rod is slidably connected to the sleeve and the connecting plate.
[0011] Preferably, the plug-in assembly includes a hinge rod, an adjusting telescopic rod II, a guide member, and a connecting ring. The hinge rod is hinged to the adjusting telescopic rod II, the adjusting telescopic rod II passes through the guide member and is slidably connected to the guide member, the connecting ring is fixedly connected to the outer wall of the adjusting telescopic rod II, and the connecting ring is elastically connected to the guide member through a connecting spring.
[0012] Preferably, the hinge rod is hinged to the first adjusting telescopic rod, and the second adjusting telescopic rod passes through the connecting member and is slidably connected to the connecting member.
[0013] Preferably, the outer wall of the connecting arm has a socket that matches the second adjusting telescopic rod. When the cargo hold lands, the fixed foot is pressed by the ground, causing the first adjusting telescopic rod to rise. The return spring is compressed, which drives the hinge rod to move, thereby causing the second adjusting telescopic rod to move out of the connector. This allows the connecting arm to rotate and be inserted into or removed from the connector. When the cargo hold is lifted, the return spring returns to its original position, causing the first adjusting telescopic rod to fall. This allows the hinge rod to drive the second adjusting telescopic rod into the socket, thus fixing the connecting arm.
[0014] This invention provides a logistics drone with a detachable cargo compartment. It offers the following advantages:
[0015] (1) The logistics drone with a detachable cargo compartment uses a limiting mechanism. When the cargo compartment lands, the fixed feet are squeezed, which automatically triggers the plug-in components to release the fixation, allowing the drone to detach quickly. When lifting, the components automatically reset and fix, eliminating the need for manual operation and improving loading and unloading efficiency.
[0016] (2) The cargo compartment of the logistics drone with a separate cargo compartment is designed separately. After the delivery is completed, the drone does not need to carry an empty cargo compartment back to the airport, which reduces the energy consumption caused by the ineffective load and extends the range. At the same time, the load space occupied by the empty cargo compartment is reduced, which can increase the amount of goods transported in a single flight and solves the problem of short range and limited transport volume caused by the return flight of the traditional fixed cargo compartment.
[0017] (3) The cargo compartment of the logistics drone with a split cargo compartment can be adapted to different specifications of cargo compartments by using the adjustment components, adjustment telescopic rod one and adjustment telescopic rod two in combination, adjusting the position of the connecting plate by the screw, and adjusting the distance between the fixed feet by the squeezing components.

[0026] The realization of the purpose, functional features and advantages of this utility model will be further explained in conjunction with the embodiments and with reference to the accompanying drawings. Detailed Implementation
[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0028] Please see Figures 1-5 This utility model proposes a logistics drone with a detachable cargo compartment, including a drone body 1 and a cargo compartment 3. A connecting arm 2 is rotatably connected to the lower side of the drone body 1, and a mounting plate 4 is fixedly connected to the upper side of the cargo compartment 3 by bolts. A connecting piece 5 is fixedly connected to the mounting plate 4, and a limiting mechanism 6 is provided on the mounting plate 4. By rotating the connecting arm 2, the connecting arm 2 is inserted into the connecting piece 5, which can initially fix the cargo compartment 3. At the same time, it is convenient to separate the cargo compartment 3 later. After the delivery is completed, there is no need for the drone to return with an empty cargo compartment, which reduces the energy consumption caused by ineffective load and extends the range. At the same time, reducing the load space occupied by the empty cargo compartment can increase the amount of goods transported in a single flight. This solves the problem of short range and limited transport capacity caused by the return flight with an empty cargo compartment in the traditional fixed cargo compartment 3.
[0029] In an embodiment of this utility model, the limiting mechanism 6 includes an adjusting component 61 and a pressing component. The adjusting component 61 is connected to the mounting plate 4, and the pressing component is connected to the adjusting component 61. A plug-in component is provided above the adjusting component 61. The adjusting component 61 includes a connecting plate 611, a screw 612, a nut 613, and an elastic telescopic rod 614. The screw 612 is fixed to the connecting plate 611, threadedly connected to the mounting plate 4, and threadedly connected to the nut 613. The two ends of the elastic telescopic rod 614 are fixed to the connecting plate 611 and the mounting plate 4, respectively. By rotating the nut 613, the distance between the connecting plate 611 and the mounting plate 4 is adjusted, thereby enabling the limiting mechanism 6 to be used for cargo compartments 3 of different sizes.
[0030] Furthermore, the extrusion assembly includes a sleeve 62, an adjusting telescopic rod 63, a fixing ring 64, and a fixing foot 65. The fixing ring 64 is fixedly connected to the outer wall of the adjusting telescopic rod 63, and the fixing ring 64 is elastically connected to the inner wall of the sleeve 62 by a return spring. The fixing foot 65 is fixedly connected to the bottom of the adjusting telescopic rod 63. The sleeve 62 is fixedly connected to the lower side of the connecting plate 611. The adjusting telescopic rod 63 passes through the sleeve 62 and the connecting plate 611, and the adjusting telescopic rod 63 is connected to the sleeve 62 and the connecting plate 611. The connecting plate 611 is slidably connected. The plug-in assembly includes a hinge rod 66, an adjusting telescopic rod 67, a guide member 68, and a connecting ring 69. The hinge rod 66 is hinged to the adjusting telescopic rod 67. The adjusting telescopic rod 67 passes through the guide member 68 and is slidably connected to the guide member 68. The connecting ring 69 is fixedly connected to the outer wall of the adjusting telescopic rod 67. The outer wall of the connecting arm 2 has a socket 21 that matches the adjusting telescopic rod 67. The connecting ring 69 and the guide member 68 are elastically connected by a connecting spring. The connecting rod 66 is hinged to the first adjusting telescopic rod 63, and the second adjusting telescopic rod 67 passes through the connecting piece 5 and is slidably connected to the connecting piece 5. By using the first adjusting telescopic rod 63 and the second adjusting telescopic rod 67, the position of the fixed foot 65 can be adjusted, thus adapting to cargo holds 3 of different sizes. When the cargo hold 3 is lifted by the connecting arm 2, the return spring extends and returns, causing the fixed ring 64 to descend, which in turn causes the first adjusting telescopic rod 63 to descend, causing the hinge rod 66 to move, so that the second adjusting telescopic rod 67 can be inserted into the socket 21 of the connecting arm 2, thereby fixing the connecting arm 2 and ensuring the stability of the connecting arm 2 and the hoisted cargo hold 3. After being transported to the designated location, when the cargo hold 3 comes into contact with the ground, the fixed foot 65 is squeezed by the ground, causing the first adjusting telescopic rod 63 to rise, the return spring to be compressed, causing the hinge rod 66 to move, which in turn causes the second adjusting telescopic rod 67 to move out of the connecting piece 5, thereby releasing the fixation of the connecting arm 2, making it easier to remove the connecting arm 2, and allowing the cargo hold 3 to be quickly separated, improving loading and unloading efficiency.
[0031] It should be noted that the above electrical components are all existing technology products. Those skilled in the art should select, install and complete the circuit debugging work according to the needs of use to ensure that all electrical appliances can work normally. The components are all general standard parts or components known to those skilled in the art. Their structure and principle can be known by those skilled in the art through technical manuals or conventional experimental methods. No specific restrictions are made here.
[0032] In use, first rotate the connecting arm 2 and insert it into the connector 5. Then, the drone body 1 lifts the cargo hold 3. During this process, the return spring extends and resets, causing the fixing ring 64 to descend. This causes the first telescopic rod 63 to descend, moving the hinge rod 66 and allowing the second telescopic rod 67 to be inserted into the socket 21 of the connecting arm 2, thus fixing the connecting arm 2 and ensuring the stability of the connecting arm 2 and the cargo hold 3. After transportation to the designated location, when the cargo hold 3 contacts the ground, the fixing foot 65 is squeezed by the ground, causing the first telescopic rod 63 to rise. The return spring is compressed, moving the hinge rod 66 and causing the second telescopic rod 67 to move out of the connector 5, thereby releasing the fixation of the connecting arm 2 and facilitating the removal of the connecting arm 2. This allows the cargo hold 3 to be quickly separated and removed.
[0033] The above description is only a preferred embodiment of the present utility model and does not limit the patent scope of the present utility model. All equivalent structural transformations made under the inventive concept of the present utility model using the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present utility model.
