Description

Technical Field

[0001] The embodiments disclosed herein relate to the field of unmanned aerial vehicle (UAV) technology, and more specifically, to a foldable transport UAV. Background Technology

[0002] With the booming development of the e-commerce industry and the explosive growth of logistics and delivery demand, traditional ground transportation methods have gradually shown their limitations in dealing with delivery challenges. Foldable transport drones have emerged to address these challenges. They aim to break through the limitations of terrain and traffic congestion, opening up new paths for express delivery, fresh food delivery, and other fields. On the one hand, their foldable design meets the requirements of modern warehousing for intensive space utilization, significantly reducing the footprint when idle. On the other hand, transport drones, with their high-speed cruising capabilities in the air, effectively shorten delivery time and improve delivery efficiency, becoming a key and highly anticipated component in the construction of a smart logistics system.

[0003] Existing foldable transport drones have many drawbacks. During the installation and fixing process, workers need to use a variety of external tools such as screwdrivers and wrenches to match the complex screws and clips one by one. The slightest mistake can ruin the entire process. The whole process not only consumes a lot of physical strength, but also wastes valuable time, causing labor and time costs to rise sharply. When it comes to folding and storing, the same dilemma arises again, still requiring the use of complicated tools. This greatly reduces the mobility and convenience of the equipment, making it difficult to meet the actual needs of efficient transportation. Therefore, improvements and optimizations are needed.

[0004] To overcome the above-mentioned defects, the embodiments of this disclosure provide a foldable transport drone, which solves the technical problems of a foldable transport drone in the prior art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a foldable transport drone, including a drone control device, a first arm fixedly mounted on the side of the drone control device, a first sleeve movably sleeved at the end of the first arm, a folding assembly fixedly mounted at one end of the first sleeve, the folding assembly including a fixed seat fixedly mounted at one end of the first sleeve, a protrusion fixedly mounted on the side of the fixed seat, a movable seat movably mounted on the side of the fixed seat, the protrusion and the movable seat being hinged to each other by rollers, and a second sleeve fixedly mounted on the side of the movable seat. The second sleeve is movably fitted onto the outer surface of the second arm. The fixed seat and the movable seat have grooves, each half of which is open. A fixed sleeve is fixedly installed inside the groove. A threaded groove is opened inside the fixed sleeve. A spring groove is opened inside the fixed sleeve and located above the threaded groove. A threaded rod is threadedly connected inside the threaded groove. A locking knob is fixedly installed at the top of the threaded rod. A first spring is fixedly connected to the bottom of the spring groove and movably fitted onto the outer surface of the threaded rod. A first half-sleeve is fixedly fitted onto the outer surface of the fixed sleeve. A second half-sleeve is fixedly installed at the top of the movable seat.

[0006] As one aspect of this utility model, a fastening component is fixedly installed on the side of the movable seat. The fastening component includes two protruding strips fixedly installed on the side of the movable seat. A strip-shaped groove is opened on the side of the fixed seat and matches the protruding strip. The depth of the strip-shaped groove is greater than the length of the protruding strip. A second spring is fixedly connected to the inner side of the strip-shaped groove. A movable plate is fixedly connected to the other end of the second spring.

[0007] As one aspect of this utility model, fastening sleeves are fixedly installed on the outer surfaces of the first sleeve and the second sleeve. The fastening sleeves are internally threaded with fixing bolts, and the two ends of the fixing bolts pass through the interior of the two fastening sleeves, with a snap-fit ​​groove opened at one end of the fixing bolt.

[0008] As one aspect of this utility model, support rods are fixedly installed on both sides of the top of the UAV control device, and the support rods are in groups of two on one side. A stabilizing rod is fixedly installed inside the support rod, and the two ends of the stabilizing rod pass through the interior of the two support rods.

[0009] As one aspect of this utility model, a battery box is fixedly installed at the bottom of the drone control device, and fixing rods are fixedly installed on both sides of the bottom of the battery box. The two ends of the fixing rods are fixedly connected to a three-way sleeve, and the two ends of the support rod pass through the inside of the three-way sleeve.

[0010] As one aspect of this utility model, a lighting fixture is fixedly installed on the outer surface of the support rod, and a lighting lamp is snapped onto the side of the lighting fixture.

[0011] As one aspect of this utility model, a flexible sleeve is fixedly sleeved on the outer surface of the stabilizer bar, and flexible sleeves are fixedly sleeved on the outer surfaces of both ends of the stabilizer bar.

[0012] As one aspect of this utility model, a battery box is fixedly installed at the bottom of the drone control device, and a battery is placed inside the battery box.

[0013] As one aspect of this utility model, the side of the fixing seat is provided with a flow groove, and both sides of the fixing seat are provided with flow grooves.

[0014] As one aspect of this utility model, the upper outer surface of the locking knob is toothed, and the locking knob is located above the fixing base.

[0015] The beneficial effects of the embodiments disclosed herein are as follows: When folding is required, the locking knob is rotated in the opposite direction. Due to the upward force of the first spring, the auxiliary locking knob rotates upward. When the binding force of the first spring on the first and second half-tubes disappears, the fixed seat and the movable seat can be smoothly separated. At the same time, the roller provides rotational support for the movable seat. Compared with traditional devices, in the installation and fixing stage, the operator only needs to apply external force to push the movable seat closer to the fixed seat. Through ingenious mechanical linkage, the two can be easily matched into a ring and firmly connected. The operation is simple and efficient, saving manpower and time costs. When the equipment needs to be stored, moved, or adjusted in space, the locking knob can be rotated in the opposite direction to trigger the elastic component, the first spring, to assist in the reset, quickly release the fixed state, and achieve large-angle folding. This greatly improves the portability and space adaptability of the equipment, making mud treatment work more flexible and convenient.

[0016] The beneficial effects of the embodiments disclosed herein are as follows: When the movable plate is squeezed, the squeezing force is transmitted to the second spring, causing the second spring to undergo elastic deformation. At the same time, a counterforce is applied to the protruding strip, which is then transmitted to the second half-tube through the movable seat, causing the second half-tube to fit tightly against the inner wall of the locking knob. Compared with traditional devices, in the assembly and fixing stage, when the key component locking knob wraps and binds the first and second half-tubes, a series of ingenious actions are initiated. The matching of the protruding strip with the strip groove and the process of the protruding strip penetrating into the inner side of the strip groove cleverly utilize the interaction between the elastic element second spring and the movable plate. This not only achieves a tight fit between the components, but also uses the reaction force to make the second half-tube firmly fit against the inner wall of the locking knob. This effectively eliminates potential gaps in the drone fuselage, greatly reduces airflow interference during flight, ensures stable and safe transportation, and greatly improves the accuracy and reliability of delivery.

[0030] Furthermore, in the description of this application, the terms "first," "second," etc., are used only to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0031] like Figures 1-6As shown, this utility model provides a foldable transport drone, including a drone control device 1. A first arm 2 is fixedly mounted on the side of the drone control device 1. A first sleeve 4 is movably sleeved at the end of the first arm 2. A folding assembly 6 is fixedly mounted at one end of the first sleeve 4. The folding assembly 6 includes a fixed seat 601 fixedly mounted at one end of the first sleeve 4. A protrusion 610 is fixedly mounted on the side of the fixed seat 601. A movable seat 611 is movably mounted on the side of the fixed seat 601. The protrusion 610 and the movable seat 611 are hinged to each other by a roller 613. A second sleeve 5 is fixedly mounted on the side of the movable seat 611 and is movably sleeved on the second arm. On the outer surface of 3, the fixed seat 601 and the movable seat 611 have grooves 602, each half of which is provided. A fixed cylinder 603 is fixedly installed inside the groove 602. A threaded groove 605 is provided inside the fixed cylinder 603. A spring groove 604 is provided inside the fixed cylinder 603 and is located above the threaded groove 605. A threaded rod 607 is threadedly connected inside the threaded groove 605. A locking knob 608 is fixedly installed on the top of the threaded rod 607. A first spring 609 is fixedly connected to the bottom of the spring groove 604 and is movably sleeved on the outer surface of the threaded rod 607. A first half-encased cylinder 606 is fixedly sleeved on the outer surface of the fixed cylinder 603. A second half-encased cylinder 612 is fixedly installed on the top of the movable seat 611.

[0032] When the operator needs to fix the first arm 2 and the second arm 3, external force is used to gradually move the movable seat 611 closer to the fixed seat 601. When the second half-tube 612 contacts the first half-tube 606, they fit together to form a complete ring. At this time, by rotating the locking knob 608, the threaded rod 607 will start to rotate. When the threaded rod 607 starts to rotate, it will gradually move downward along the thread groove 605. At the same time, the downward movement of the locking knob 608 will compress the first spring 609, causing elastic deformation. When the annular groove on the bottom side of the locking knob 608 is completely closed... When the first half-tube 606 and the second half-tube 612 are wrapped, the first arm 2 and the second arm 3 are fixed. When folding is required, the locking knob 608 is rotated in the opposite direction. Due to the upward force of the first spring 609, the auxiliary locking knob 608 rotates upward. When the binding force of the first spring 609 on the first half-tube 606 and the second half-tube 612 disappears, the fixed seat 601 and the movable seat 611 can be smoothly separated. At the same time, the roller 613 provides rotational support for the movable seat 611, so that the first sleeve tube 4 and the second sleeve tube 5, the first arm 2 and the second arm 3 can be folded at a large angle.

[0033] When folding is required, rotating the locking knob 608 in the opposite direction triggers the first spring 609 to exert an upward force, causing the auxiliary locking knob 608 to rotate upward. When the binding force of the first spring 609 on the first half-tube 606 and the second half-tube 612 disappears, the fixed seat 601 and the movable seat 611 can be smoothly separated. At the same time, the roller 613 provides rotational support for the movable seat 611. Compared with traditional devices, during the installation and fixing stage, the operator only needs to apply external force to push the movable seat 611 closer to the fixed seat 601. Through ingenious mechanical linkage, the two can easily be made to fit into a ring and be securely connected. The operation is simple and efficient, saving manpower and time costs. When the equipment needs to be stored, moved, or adjusted in space, rotating the locking knob 608 in the opposite direction will trigger the elastic component, the first spring 609, to assist in the reset, quickly releasing the fixed state and achieving large-angle folding. This greatly improves the portability and space adaptability of the equipment, making mud treatment work more flexible and convenient.

[0034] In some instances, a fastening assembly 7 is fixedly mounted on the side of the movable seat 611. The fastening assembly 7 includes two protrusions 701 fixedly mounted on the side of the movable seat 611. A strip-shaped groove 702 is provided on the side of the fixed seat 601 and matches the protrusions 701. The depth of the strip-shaped groove 702 is greater than the length of the protrusions 701. A second spring 703 is fixedly connected to the inner side of the strip-shaped groove 702. The other end of the second spring 703 is fixedly connected to a movable plate 704.

[0035] When the locking knob 608 wraps and binds the first half-tube 606 and the second half-tube 612, the protrusion 701 matches the strip groove 702. At the same time, as the movable seat 611 gradually matches the fixed seat 601, the protrusion 701 gradually penetrates into the strip groove 702. When it penetrates into the inner side of the strip groove 702, it will squeeze the movable plate 704. When the movable plate 704 is squeezed, it will transmit the squeezing force to the second spring 703, thereby causing the second spring 703 to undergo elastic deformation. At the same time, it will give the protrusion 701 a reverse force. Then, the protrusion 701 will transmit the force to the second half-tube 612 through the movable seat 611, so that the second half-tube 612 is tightly attached to the inner wall of the locking knob 608, avoiding gaps that could cause instability during the transport of the drone.

[0036] When the movable plate 704 is compressed, the compressive force is transmitted to the second spring 703, causing the second spring 703 to undergo elastic deformation. Simultaneously, a counterforce is applied to the protrusion 701, which is then transmitted through the movable seat 611 to the second semi-encasing 612, causing the second semi-encasing 612 to tightly adhere to the inner wall of the locking knob 608. Compared to traditional devices, in the assembly and fixing process, when the key component, the locking knob 608, wraps and binds the first semi-encasing 606 and the second semi-encasing 612, a series of precise... The ingenious combination is immediately activated. The fit between the protrusion 701 and the groove 702, and the process of the protrusion 701 penetrating into the inner side of the groove 702, cleverly utilize the interaction between the elastic element second spring 703 and the movable plate 704. This not only achieves a tight fit between the components, but also uses the reaction force to make the second half-cup 612 firmly adhere to the inner wall of the locking knob 608. This effectively eliminates potential gaps in the drone body, greatly reduces airflow interference during flight, ensures a stable and safe transportation process, and greatly improves the accuracy and reliability of delivery.

[0037] In some instances, fastening sleeves 8 are fixedly installed on the outer surfaces of the first sleeve 4 and the second sleeve 5. The fastening sleeve 8 is internally threaded with a fixing bolt 9, and both ends of the fixing bolt 9 pass through the interior of the two fastening sleeves 8, with a snap-fit ​​groove opened at one end of the fixing bolt 9.

[0038] The fixing bolt 9 passes through the two fastening sleeves 8 at both ends, and one end of the fixing bolt 9 has a snap-fit ​​groove, which makes it easy for the workers to remove the first sleeve 4 and the second sleeve 5 from the first arm 2 and the second arm 3.

[0039] In some instances, support rods 13 are fixedly installed on both sides of the top of the UAV control device 1, and the support rods 13 are arranged in two groups on one side. Stabilizing rods 14 are fixedly installed inside the support rods 13, and the two ends of the stabilizing rods 14 pass through the interior of the two support rods 13.

[0040] A stabilizing rod 14 is fixedly installed inside the support rod 13, with both ends of the stabilizing rod 14 passing through the two support rods 13. This effectively provides support for the entire drone during its ascent and descent.

[0041] In some instances, a battery box 11 is fixedly installed at the bottom of the drone control device 1, and fixing rods 18 are fixedly installed on both sides of the bottom of the battery box 11. The two ends of the fixing rods 18 are fixedly connected to a three-way sleeve 19, and the two ends of the support rod 13 pass through the inside of the three-way sleeve 19.

[0042] The fixed rod 18 is fixedly connected to the two ends of the three-way sleeve 19, and the two ends of the support rod 13 pass through the inside of the three-way sleeve 19. This can effectively assist the support rod 13 and the stabilizer rod 14, and increase the impact resistance of the entire drone.

[0043] In some instances, a lighting fixture 16 is fixedly mounted on the outer surface of the support rod 13, and a lighting lamp 17 is snapped onto the side of the lighting fixture 16.

[0044] The lighting fixture 16 has a lighting lamp 17 that is snapped onto the side, which can provide lighting for the drone while it is in flight. The snap-fit ​​structure also avoids the need for disassembly and replacement.

[0045] In some instances, a flexible sleeve 15 is fixedly fitted onto the outer surface of the stabilizer bar 14, and flexible sleeves 15 are fixedly fitted onto the outer surfaces of both ends of the stabilizer bar 14.

[0046] The flexible sleeves 15 are fixedly sleeved on the outer surfaces of both ends of the stabilizer bar 14, which can effectively buffer the impact when the drone lands, avoiding excessive impact and damage to the drone.

[0047] In some instances, a battery box 11 is fixedly mounted on the bottom of the drone control unit 1, and a battery 12 is placed inside the battery box 11.

[0048] A battery box 11 is fixedly installed at the bottom of the drone control device 1, and the battery 12 is located inside the battery box 11, so that the battery box 11 can provide physical protection for the battery 12 and prevent the battery 12 from being easily damaged by external physical forces.

[0049] In some instances, the side of the fixing seat 601 is provided with a flow groove 10, and both sides of the fixing seat 601 are provided with flow grooves 10.

[0050] With flow channels 10 provided on both sides of the fixed base 601, rainwater can be discharged through the flow channels 10 during rainy weather, reducing the resistance during rainwater flow.

[0051] In some instances, the upper outer surface of the locking knob 608 is toothed, and the locking knob 608 is located above the mounting base 601.

[0052] The toothed shape on the upper outer surface of the locking knob 608 increases friction, making it easier for operators to rotate the locking knob 608.

[0053] The working principle and usage process of this utility model are as follows: When the operator needs to fix the first arm 2 and the second arm 3, external force is used to gradually move the movable seat 611 closer to the fixed seat 601. When the second half-tube 612 contacts the first half-tube 606, they fit together to form a complete ring. At this time, by rotating the locking knob 608, the threaded rod 607 will start to rotate. When the threaded rod 607 starts to rotate, it will gradually move downward along the thread groove 605. At the same time, the downward movement of the locking knob 608 will compress the first spring 609 to produce elastic deformation. When the locking knob 608 reaches its bottom... When the annular groove on the side is completely covered by the first half-cover 606 and the second half-cover 612, the first arm 2 and the second arm 3 are fixed. When folding is required, the locking knob 608 is rotated in the opposite direction. Due to the upward force of the first spring 609, the auxiliary locking knob 608 rotates upward. When the binding force of the first spring 609 on the first half-cover 606 and the second half-cover 612 disappears, the fixed seat 601 and the movable seat 611 can be smoothly separated. At the same time, the roller 613 provides rotational support for the movable seat 611, so that the first sleeve 4 and the second sleeve 5, the first arm 2 and the second arm 3 can be folded at a large angle.

[0054] When the locking knob 608 wraps and binds the first half-tube 606 and the second half-tube 612, the protrusion 701 matches the strip groove 702. At the same time, as the movable seat 611 gradually matches the fixed seat 601, the protrusion 701 gradually penetrates into the strip groove 702. When it penetrates into the inner side of the strip groove 702, it will squeeze the movable plate 704. When the movable plate 704 is squeezed, it will transmit the squeezing force to the second spring 703, thereby causing the second spring 703 to undergo elastic deformation. At the same time, it will give the protrusion 701 a reverse force. Then, the protrusion 701 will transmit the force to the second half-tube 612 through the movable seat 611, so that the second half-tube 612 is tightly attached to the inner wall of the locking knob 608, avoiding gaps that could cause instability during the transport of the drone.

[0055] It should be noted that the above embodiments are only used to illustrate the technical solutions of this disclosure and are not intended to limit it. Although this disclosure has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this disclosure without departing from the spirit and scope of the technical solutions of this disclosure, and all such modifications or substitutions should be covered within the scope of the claims of this disclosure.
