Description

Technical Field

[0001] This utility model relates to the field of logistics transportation drone technology, specifically to an anti-detachment rack for adjustable storage space of logistics transportation drones. Background Technology

[0002] Logistics drones are an innovative technological product in the modern logistics field. Leveraging advanced flight control systems and navigation technology, they achieve autonomous flight and precise positioning. These drones possess efficient and flexible transportation capabilities, quickly traversing urban and remote areas, avoiding ground traffic congestion, and significantly shortening delivery times. Simultaneously, their design emphasizes safety and stability, and they can carry a certain weight of goods. Logistics drones are gradually changing traditional logistics models, bringing new opportunities for industry development.

[0003] Chinese patent CN218086027U discloses an integrated amphibious unmanned vehicle and drone device, comprising a drone body with four arms. Drone motors are fixed to the upper surfaces of the arms, and drone propellers are connected to the outputs of the motors. Unmanned vehicle motors are fixed to the lower surfaces of the arms, and unmanned vehicle wheels are connected to the outputs of the motors. A GPS inertial navigation system is fixed to the top of the drone body, and a binocular camera is mounted on the front. A storage box is mounted on the bottom of the drone body via a mounting bracket, which includes four connecting columns and a mounting base. A central controller is fixed to the upper surface of the mounting base, and a battery is installed inside the storage box. This integrated amphibious unmanned vehicle and drone device solves the problem that existing logistics and rescue operations still largely rely on manpower, and that some drone-unmanned vehicle collaborative devices often have low efficiency.

[0004] The aforementioned patent document describes an integrated land-air amphibious unmanned vehicle and drone device. This device utilizes a cargo storage box located at the bottom of the drone's fuselage. When the drone transports goods, the cargo is placed inside the storage box. However, the internal space of the cargo box is not adjustable, causing the cargo to shift due to the drone's inertia during takeoff and landing. Therefore, a non-detachment frame with adjustable storage space for logistics transport drones is proposed. Utility Model Content

[0005] To address the aforementioned issues, an adjustable storage space anti-detachment frame for logistics transport drones is provided. This frame utilizes a hydraulic telescopic component that extends or retracts at its output end, enabling the component to move a connecting frame longitudinally. Simultaneously, the connecting frame, via lifting lugs, moves a floating plate inside the cargo box longitudinally. This allows for adjustment of the cargo box's internal storage space through the longitudinal movement of the floating plate, thus resolving the problem of the cargo box's internal space being unadjustable.

[0006] To address the existing technical problems, this application provides an anti-detachment frame for adjustable storage space of a logistics transport drone. The anti-detachment frame includes a cargo box located at the bottom of the logistics transport drone, a liftable float located inside the cargo box, and a clamping mechanism located inside the cargo box for securing the cargo. The float has symmetrically arranged lifting lugs on both sides.

[0007] Hydraulic telescopic components are fixed longitudinally on both sides of the cargo box. A connecting frame is fixed to the output end of the hydraulic telescopic component. Mounting rods that can be connected to lifting lugs are fixed longitudinally at the bottom of both ends of the connecting frame.

[0008] As one technical solution of this application, four mounting posts are equidistantly arranged on the upper surface of the cargo box inside around the central axis;

[0009] The bottom end of the mounting column is fixed with a limiting plate, and a rotatable rotating seat is installed on the upper end surface of the limiting plate. A fixing rod is installed longitudinally on the upper end surface of the rotating seat near the edge.

[0010] The mounting post is externally fitted with a clamping mechanism that can rotate along its central axis, and the non-working end of the clamping mechanism can be hinged to the fixing rod.

[0011] As one technical solution of this application, the clamping mechanism includes an arc-shaped rod, one end of which is hinged to a push-pull rod, and the end of the push-pull rod away from the arc-shaped rod is hinged to a fixed rod;

[0012] The arc-shaped rod has a mounting hole on the side near the push-pull rod, which allows it to be installed on the outside of the mounting column;

[0013] The end of the arc-shaped rod away from the push-pull rod is longitudinally fitted with a clamping rod for securing the goods.

[0014] As one technical solution of this application, an annular slide rail is fixed on the upper end surface of the limiting plate;

[0015] The lower end face of the rotating seat is provided with an annular limiting groove that can slide and engage with the annular slide rail.

[0016] As one technical solution of this application, the cargo box has longitudinally provided clearance grooves on both sides for limiting the movement, and the lifting lugs can slide along the clearance grooves.

[0017] As one technical solution of this application, the logistics transport drone has several support legs symmetrically fixed on the side of the bottom near the cargo box, and a float box that can float on the water surface is fixed on the side of the support legs.

[0018] As one technical solution of this application, a support plate is installed on the outside of the support leg, and the support plate is used to support the cargo box.

[0019] As one technical solution of this application, the cargo box is also provided with a door that can be opened or closed, and the door is located on the side adjacent to the clearance groove.

[0020] The advantages of this utility model compared to the prior art are:

[0021] 1. This application utilizes the outward extension or retraction of the output end of a hydraulic telescopic component, enabling the component to drive the connecting frame at its output end to move longitudinally. Simultaneously, the connecting frame, via lifting lugs, drives the floats inside the cargo box to move longitudinally in sync. This allows for adjustment of the storage space inside the cargo box through the longitudinal movement of the floats, solving the problem of the inability to adjust the internal space of the cargo box.

[0022] 2. This application utilizes a servo motor to drive a rotating base, which in turn drives a fixed rod, which in turn drives a push-pull rod to push an arc-shaped rod. Simultaneously, the arc-shaped rod rotates around the central axis of the mounting column through the mounting hole. At this time, the arc-shaped rod drives the clamping rod to rotate synchronously around the central axis of the mounting column. This achieves the fixing or release of the goods by the clamping rod, ensuring the stability of the goods during transportation. Attached Figure Description

Detailed Implementation

[0034] To further understand the features, technical means, and specific objectives and functions achieved by this utility model, the following detailed description of this utility model is provided in conjunction with the accompanying drawings and specific embodiments.

[0035] See Figures 1-10 As shown, an adjustable storage space anti-detachment frame for a logistics transport drone is applied to a logistics transport drone 1. The adjustable storage space anti-detachment frame includes a cargo box 2 set at the bottom of the logistics transport drone 1, a float 4 set inside the cargo box 2 that can be raised and lowered, and a clamping mechanism 7 set inside the cargo box 2 for fixing the cargo. The float 4 is symmetrically provided with lifting lugs 41 on both sides.

[0036] Hydraulic telescopic components 3 are fixed longitudinally on both sides of the cargo box 2. A connecting frame 31 is fixed at the output end of the hydraulic telescopic component 3. Mounting rods 32 that can be connected to the lifting lugs 41 are fixed longitudinally at the bottom of both ends of the connecting frame 31.

[0037] When the output end of the hydraulic telescopic component 3 extends or retracts, it drives the connecting frame 31 at its output end to move longitudinally. Simultaneously, the connecting frame 31, through the lifting lug 41, drives the float 4 inside the cargo box 2 to move longitudinally in sync. When the float 4 moves upward, its upper surface gradually approaches the top of the cargo box 2, reducing the storage space inside. When the float 4 moves downward, it gradually moves away from the top of the cargo box 2, increasing the storage space inside. This allows for adjustment of the storage space inside the cargo box 2.

[0038] See Figure 6 , Figure 7 , Figure 8 and Figure 9 As shown, four mounting posts 23 are equidistantly arranged on the upper surface of the interior of the cargo box 2 around the central axis;

[0039] The bottom end of the mounting column 23 is fixed with a limiting plate 6, and a rotatable rotating seat 8 is installed on the upper end surface of the limiting plate 6. A fixing rod 81 is installed longitudinally on the upper end surface of the rotating seat 8 near the edge.

[0040] The mounting post 23 is externally mounted with a clamping mechanism 7 that can rotate along its central axis. The non-working end of the clamping mechanism 7 can be hinged to the fixing rod 81.

[0041] A servo motor 5 is fixed at the center of the top of the cargo box 2. The output shaft of the servo motor 5 extends downward into the interior of the cargo box 2 and is fixed to the rotating base 8. When the servo motor 5 is started, it drives the rotating base 8 to rotate through the output shaft. At this time, the rotating base 8 drives the non-working end of the clamping mechanism 7 through the fixed rod 81, so that the clamping mechanism 7 can rotate around the central axis of the mounting column 23, thereby achieving the purpose of clamping the goods by the working end of the clamping mechanism 7.

[0042] See Figure 6 , Figure 7 , Figure 8 , Figure 9 and Figure 10 As shown, the clamping mechanism 7 includes an arc-shaped rod 71, one end of which is hinged to a push-pull rod 73, and the end of the push-pull rod 73 away from the arc-shaped rod 71 is hinged to a fixed rod 81.

[0043] The curved rod 71 has a mounting hole 72 on the side near the push-pull rod 73, which can be installed on the outside of the mounting post 23;

[0044] The end of the curved rod 71 away from the push-pull rod 73 is longitudinally fitted with a clamping rod 74 for securing the goods.

[0045] The rotation of the rotating seat 8 drives the fixed rod 81, which in turn drives the push-pull rod 73, which in turn pushes the arc-shaped rod 71. Simultaneously, the arc-shaped rod 71 rotates around the central axis of the mounting post 23 through the mounting hole 72. At this time, the arc-shaped rod 71 drives the clamping rod 74 to rotate synchronously around the central axis of the mounting post 23. This allows the clamping rod 74 to fix or release the goods, ensuring the stability of the goods during transportation.

[0046] See Figure 8 and Figure 9 As shown, an annular slide rail 61 is fixed to the upper end face of the limiting plate 6;

[0047] The lower end face of the rotating seat 8 is provided with an annular limiting groove 82 that can slide and engage with the annular slide rail 61.

[0048] To ensure the stability of the rotating seat 8, an annular limiting groove 82 is provided on the lower end face of the rotating seat 8, allowing the annular limiting groove 82 to slide in cooperation with the annular slide rail 61. When the rotating seat 8 rotates, it can slide along the annular slide rail 61 through the annular limiting groove 82, effectively preventing displacement of the rotating seat 8 during rotation.

[0049] See Figure 4 and Figure 5 As shown, the cargo box 2 has longitudinal relief grooves 21 on both sides for limiting the position, and the lifting lugs 41 can slide along the relief grooves 21.

[0050] To ensure the stability of the float 4, relief grooves 21 are symmetrically provided on both sides of the cargo box 2 for the lifting lugs 41 to slide. When the float 4 moves longitudinally, the float 4 can drive the lifting lugs 41 to move along the inside of the relief grooves 21, thus preventing the float 4 from shifting during lifting and lowering.

[0051] See Figure 1 , Figure 2 and Figure 3 As shown, several support legs 12 are symmetrically fixed on the side of the bottom of the logistics transport drone 1 near the cargo box 2, and float boxes 13 that can float on the water surface are fixed on the side of the support legs 12.

[0052] By installing several support legs 12 at the bottom of the logistics transport drone 1, the drone can land on land when it lands. By symmetrically installing float boxes 13 on both sides of the bottom of the support legs 12, the drone can land on the water.

[0053] See Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, a support plate 14 is installed on the outside of the support leg 12, and the support plate 14 is used to support the cargo box 2.

[0054] By fixing the support plate 14 to the support leg 12, the float plate 4 can fix the bottom of the support leg 12, thereby increasing the stability of the support leg 12. At the same time, the cargo box 2 is fixed to the upper surface of the support plate 14, so that the support plate 14 can support the body of the cargo box 2 and ensure the stability of the body.

[0055] See Figure 4 As shown, the cargo box 2 is also equipped with a door 22 that can be opened or closed, and the door 22 is located on the side adjacent to the clearance groove 21.

[0056] By setting a door 22 on the cargo box 2, the door 22 can close or open the cargo box 2, thereby facilitating the loading and unloading of goods.

[0057] The above embodiments only illustrate one or more implementations of this utility model, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of this utility model. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the appended claims.
