Description

Technical Field

[0001] This utility model relates to the field of unmanned aerial vehicle (UAV) technology, and specifically to a small UAV mounting and deployment device. Background Technology

[0002] Drone technology has developed rapidly in recent years, and its applications have expanded from the military field to many civilian fields such as surveying, logistics, agricultural plant protection, and emergency rescue. However, the capabilities of a single drone platform are often limited. Although small drones are flexible and have low take-off and landing requirements, they are limited by their endurance and payload capacity, making it difficult to perform long-distance, long-endurance missions. Large drones, on the other hand, have the advantages of long range and large payload, but their large size and take-off and landing requirements limit their direct application in complex environments (such as urban buildings, jungles, and mountains).

[0003] To address these contradictions, the industry has proposed a collaborative operation model of "mother drone + daughter drone," in which a large drone carries a smaller drone to the target airspace for deployment. This model places clear technical requirements on the drone-mounted deployment device, requiring it to be compact and lightweight to accommodate the load and space constraints of the mother drone; at the same time, it must ensure the safety of the daughter drone during long-distance flight and reliable separation at the moment of deployment.

[0004] Currently, existing drone-mounted delivery systems suffer from the following main problems: First, complex structure and poor adaptability. Many large delivery systems originating from the industrial sector are complex in structure, excessively large in size and weight, and cannot be effectively carried by small and medium-sized drones, let alone adapted to the delivery needs of lightweight small drones or standard mission payloads. Second, limited functionality and lack of effective protection: Some delivery systems on the market with simple structures often only have basic release functions. During the mother aircraft's flight, they cannot provide effective physical protection for the small drones or equipment they are carrying, exposing them directly to airflow, rain, dust, and even low temperatures, which can easily lead to equipment damage or performance degradation. Third, harsh delivery environment and low separation reliability. Crucially, traditional delivery systems typically release the load directly under the mother aircraft's fuselage. In this case, the small drone or its payload will immediately be caught in the powerful and turbulent downwash generated by the mother aircraft's rotor. This harsh aerodynamic environment can easily cause the small drone to lose control, tumble, or even collide with the mother aircraft during startup or wing deployment, resulting in mission failure and extremely high risk. Utility Model Content

[0005] The purpose of this invention is to provide a small drone mounting and delivery device to overcome the shortcomings of existing drone mounting and delivery devices, such as complex structure, poor adaptability, lack of effective protection during flight, and low separation reliability due to airflow interference from the mother aircraft at the moment of delivery.

[0006] To achieve the above objectives, this utility model provides a small unmanned aerial vehicle (UAV) mounting and deployment device, comprising: The mother machine body; The linear drive unit is provided in at least two sets, which are arranged opposite and symmetrically on both sides of the bottom of the mother machine body, forming a mounting space with a delivery port on at least one side of the bottom of the mother machine body; A connecting crossbar is connected to the drive end of the linear drive unit; The loading and unloading mechanism is installed below the main body of the machine via the connecting crossbars. It includes a mounting plate erected between the connecting crossbars, a load-bearing platform slidably mounted on the upper surface of the mounting plate for bearing the load, a clamping mechanism disposed on the load-bearing platform for fixing the load, and a driving mechanism disposed on the mounting plate for driving the load-bearing platform to extend out of the loading port from the mounting space or retract from the mounting space into the mounting space. The linear drive unit can drive the crossbars to move the load-bearing platform toward and away from the main body of the machine, thereby increasing and decreasing the space above the load-bearing platform. A telescopic protective cover is installed on the lower part of the mother machine body and covers the mounting space; the telescopic protective cover has a protective state of descending and unfolding to cover the cargo platform and a deployment state of rising and retracting to expose the cargo platform.

[0007] Through the above technical solution, the suspension mechanism composed of the linear drive unit and the connecting crossbar realizes the integration and space optimization of the load-bearing and delivery mechanism. It is not only compact and highly adaptable, but also can flexibly adjust the size of the mounting space to adapt to loads of different sizes, overcoming the problems of bulky and poor adaptability of existing technology devices.

[0008] As an active protection unit, the telescopic protective shield forms a physical protective barrier during flight, providing protection against environmental factors such as airflow and rain for the load, thus solving the problems of existing technologies having limited functionality and lacking effective protection.

[0009] By controlling the telescopic protective cover, an ideal separation environment with no obstructions and stable airflow is created for the payload, ensuring that the small drone can start up safely and fly away stably. This avoids the risk of collision and loss of control caused by direct release in the mother aircraft's turbulence zone, thereby achieving a comprehensive improvement in the reliability, safety, and environmental adaptability of the payload release mission.

[0010] The technical solution of this utility model unifies compact layout, active protection and reliable delivery, and solves the problems of traditional mounted delivery devices.

The lifting drive unit drives the telescopic protective cover connected to the cover mounting plate to move up and down, so that the telescopic protective cover switches between a protective state and a deployment state.

[0023] The following provides a detailed description of specific embodiments of the present invention. It should be understood that the specific embodiments described herein are for illustrative and explanatory purposes only and are not intended to limit the scope of the invention.

[0024] In this invention, unless otherwise stated, directional terms such as "upper" and "lower" generally refer to the orientation in the assembled and used state. "Inner" and "outer" refer to the inner and outer sides relative to the outline of each component itself.

[0025] It should be noted that the terms "first," "second," etc., in the specification, claims, and accompanying drawings of this invention are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence. It should be understood that such data can be interchanged where appropriate for the embodiments of the invention described herein. Furthermore, the terms "comprising" and "having," and any variations thereof, are intended to cover non-exclusive inclusion; for example, a process, method, system, product, or apparatus that comprises a series of steps or units is not necessarily limited to those steps or units explicitly listed, but may include other steps or units not explicitly listed or inherent to such processes, methods, products, or apparatus.

[0026] This utility model provides a small drone mounting and deployment device, such as... Figures 1-5 As shown, the device includes a mother machine body 1, a linear drive unit 2, a connecting crossbar 3, a load-bearing and delivery mechanism, and a telescopic protective cover 4.

[0027] Linear drive unit 2 The linear drive unit 2 can be an electric push rod, with at least two sets arranged symmetrically on both sides of the bottom of the machine body 1, forming a loading space with a loading port on at least one side. A connecting crossbar 3 is connected to the drive end of the linear drive unit 2. The linear drive unit 2 can move vertically by driving the connecting crossbar 3 to adjust the height of the loading space and accommodate loads of different sizes.

[0028] Delivery and distribution agencies The load-bearing and delivery mechanism is mounted below the mother machine body 1 via the connecting crossbars 3. It includes a mounting plate 10 erected between the connecting crossbars 3, a load-bearing platform 15 slidably mounted on the upper surface of the mounting plate 10 for bearing the load, a clamping mechanism mounted on the load-bearing platform 15 for fixing the load, and a drive mechanism mounted on the mounting plate 10 for driving the load-bearing platform 15 to extend from the loading space into the delivery port or retract from the loading space into the loading space. The linear drive unit 2 can drive the crossbars 3 to move the load-bearing platform 15 toward and away from the mother machine body 1, thereby increasing and decreasing the space above the load-bearing platform 15.

[0029] On both sides of the mounting plate 10, corresponding to the positions of the connecting crossbar 3, buckles 9 are respectively installed, and the buckles 9 form a detachable fastening connection with the connecting crossbar 3 on the corresponding side.

[0030] This utility model provides three specific implementation methods for the driving mechanism: Specific Implementation Method 1 The drive mechanism includes a drive screw, a drive nut, a screw drive motor, and a connecting part. The drive screw is rotatably mounted on the mounting plate 10 via a bearing seat, and its axial direction is consistent with the sliding direction of the loading platform 15. The drive nut is fitted onto and threadedly engages with the drive screw. The screw drive motor is fixed on the mounting plate 10, and its output shaft is connected to one end of the drive screw. The connecting part fixes the drive nut to the bottom of the loading platform 15. The screw drive motor drives the screw to rotate, causing the drive nut and the loading platform 15 to move linearly along the axial direction of the drive screw. Specific Implementation Method Two The drive mechanism includes a linear motor stator 31, a linear motor mover 32, and a mover connecting frame 33. The linear motor stator 31 is fixedly mounted on the mounting plate 10, and its length direction is consistent with the sliding direction of the loading platform 15. The linear motor mover 32 is magnetically coupled to the linear motor stator 31 and can move linearly along its length direction. One end of the mover connecting frame 33 is fixedly connected to the linear motor mover 32, and the other end is fixedly connected to the bottom of the loading platform 15. By controlling the electromagnetic field of the linear motor stator 31, the linear motor mover 32 and the loading platform 15 are driven to perform synchronous linear motion. Specific Implementation Method 3 The driving mechanism includes a drive motor 11 mounted on the mounting plate 10. The mounting plate 10 has a main drive groove 12, and the output end of the drive motor 11 has a friction drive wheel 13 extending into the main drive groove 12. A sliding base 18 is provided at the bottom of the loading platform 15, and a driven groove 19 is provided on the sliding base 18 that engages with the friction drive wheel 13. The drive motor 11 drives the loading platform 15 to move through the engagement of the friction drive wheel 13 and the driven groove 19, while the load-bearing slider 20 slides along the limiting groove 14. At least one side of the main drive groove 12 has a limiting groove 14, and at least one side of the sliding base 18 has a load-bearing slider 20 that slides with the limiting groove 14. The load-bearing slider 20 slides along the limiting groove 14 to limit the movement trajectory of the loading platform 15 and withstand overturning moments.

[0033] The clamping mechanism includes multiple sets of clamping plates 17. At least two sets of opposing screw mounting grooves 16 are provided on the upper surface of the loading platform 15, and ball screws are installed within the screw mounting grooves 16. The clamping plates 17 are movably mounted on the loading platform 15 and connected to the screw nut of the ball screw. Each clamping plate 17 includes a connecting portion perpendicular to the loading platform 15 and a hook portion extending parallel to the loading platform 15. By driving the rotation of the ball screw, the clamping plates 17 can be moved relative to each other to clamp or release the load.

[0034] Furthermore, the buckle 17 includes a connecting portion and a hook portion. The connecting portion is perpendicular to the loading platform 15 and connected to the screw nut of the ball screw. One end of the hook portion is connected to the connecting portion, and the other end extends in a direction parallel to the loading platform 15.

[0035] The driving force of a single friction drive wheel 13 is limited by the motor torque and the coefficient of friction. When facing heavier submachine or objects, there is a risk of insufficient driving force, slippage, or even jamming. Therefore, multiple friction drive wheels 13 are arranged at intervals along the length of the main drive groove 12. Using multiple drive wheels in parallel effectively distributes the total driving load across multiple contact points. This allows the device to stably and reliably deliver heavier loads, greatly expanding its application range.

[0036] It should be noted that the friction drive wheel 13 only contacts one side of the driven slide groove 19, and cannot contact both sides simultaneously. If there are two driven slide grooves 19, the friction drive wheels 13 in the two driven slide grooves 19 contact the side wall of the driven slide groove 19 on the same side. Specifically, if there are two driven slide grooves 19, the friction drive wheel 13 in the left driven slide groove contacts the right wall of the left driven slide groove, and the friction drive wheel 13 in the right driven slide groove contacts the right wall of the right driven slide groove.

[0037] Telescopic protective cover 4 A telescopic protective cover 4 is installed on the lower part of the mother machine body 1 and encloses the mounting space; specifically, it is a telescopic corrugated cover. A cover mounting plate 5 is connected to the bottom edge of the telescopic protective cover 4, and a lifting drive unit is provided on the lower surface of the mother machine body 1. The lifting drive unit includes a servo motor mounting base 6 located on the lower surface of the mother machine body 1. A drive arm 7 is rotatably mounted inside the drive base 6. A guide groove 8 is provided on the cover mounting plate 5, and the end of the drive arm 7 slides into the guide groove 8. The rotation of the drive arm 7 pushes the cover mounting plate 5 to rise and fall, thereby switching the telescopic protective cover 4 between a lowered, deployed protective state and an raised, retracted deployment state.

[0038] The mothership 1 adopts a multi-rotor layout, with multiple wings evenly spaced along its circumference. The launch port is located in the space between adjacent wings, ensuring that the load has unobstructed takeoff airspace after the cargo platform 15 extends. Generally, the mothership typically carries four wings, evenly spaced circumferentially. If the mothership frame is circular, the four wings are rotationally symmetrical about the frame's axis. If the mothership frame is rectangular, the four wings are typically located at several corners of the rectangle, with the launch port located along the rectangle's side and in the space between two adjacent wings.

[0039] When in the carrying state, the linear drive unit 2 is adjusted to a suitable height, the load is fixed on the loading platform 15, and the telescopic protective cover 4 is in a lowered and deployed protective state to protect the load.

[0040] When the machine reaches the delivery area, the telescopic protective cover 4 is first raised and retracted to the delivery state, exposing the cargo platform 15. Then, the drive mechanism operates to extend the cargo platform 15 outward from the mounting space through the delivery port. Finally, the load is released, completing the delivery operation. After delivery, the drive mechanism retracts the cargo platform 15 back into the mounting space, and the telescopic protective cover 4 returns to its protective state.

[0041] Through the above technical solution, the suspension mechanism composed of the linear drive unit and the connecting crossbar realizes the integration and space optimization of the load-bearing and delivery mechanism. It is not only compact and highly adaptable, but also can flexibly adjust the size of the mounting space to adapt to loads of different sizes, overcoming the problems of bulky and poor adaptability of existing technology devices.

[0042] As an active protection unit, the telescopic protective shield forms a physical protective barrier during flight, providing protection against environmental factors such as airflow and rain for the load, thus solving the problems of existing technologies having limited functionality and lacking effective protection.

[0043] By controlling the telescopic protective cover, an ideal separation environment with no obstructions and stable airflow is created for the payload, ensuring that the small drone can start up safely and fly away stably. This avoids the risk of collision and loss of control caused by direct release in the mother aircraft's turbulence zone, thereby achieving a comprehensive improvement in the reliability, safety, and environmental adaptability of the payload release mission.

[0044] The small drone mounting and delivery device of this invention overcomes the problems of existing drone mounting and delivery devices, such as complex structure, poor adaptability, lack of effective protection during flight, and low separation reliability caused by airflow interference from the mother aircraft at the moment of delivery.

[0045] The preferred embodiments of the present invention have been described in detail above. However, the present invention is not limited to the specific details of the above embodiments. Within the scope of the technical concept of the present invention, various simple modifications can be made to the technical solution of the present invention, and these simple modifications all fall within the protection scope of the present invention.

[0046] It should also be noted that the various specific technical features described in the above embodiments can be combined in any suitable manner without contradiction. To avoid unnecessary repetition, this utility model will not describe the various possible combinations separately.

[0047] Furthermore, various different embodiments of this utility model can be combined in any way, as long as they do not violate the spirit of this utility model, they should also be regarded as the content disclosed by this utility model.
