Description

Technical Field

[0001] This application relates to the field of drone storage technology, and more specifically, to a foldable drone nest. Background Technology

[0002] With the rapid development of drone technology, drone nests, as a crucial infrastructure ensuring autonomous take-off and landing, charging, and mission scheduling for drones, are increasingly diversified in design and application scenarios. Particularly in areas such as logistics and delivery, agricultural monitoring, smart cities, and disaster emergency response, drone nests provide critical support for the automated operation of drones.

[0003] Currently, existing foldable drone nests typically employ a modular design, including charging, communication, and control modules, enabling rapid charging, data transmission, and scheduling management of drones. However, traditional foldable drone nests have limitations in adapting to complex terrain, especially when housing drones. Due to uneven ground, the nest struggles to maintain a horizontal position relative to the ground, which not only affects the smooth landing of the drone but may also increase the risk of equipment damage. Utility Model Content

[0004] To overcome the above deficiencies, this application provides a foldable drone nest to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the technical solution adopted by this utility model to solve its technical problem is as follows: A foldable drone nest includes a nest body and a drone mounted on top of the nest body. The nest body is characterized by having four leveling components bolted to its four bottom corners, with four anti-slip blocks glued to the bottom ends of each leveling component. An auxiliary opening and closing component is bolted to the inner surface of the nest body, and two protective covers are bolted to both ends of the auxiliary opening and closing component. The two protective covers approach each other through the auxiliary opening and closing component and enclose the drone.

[0006] Furthermore, the leveling assembly includes a telescopic cylinder, a flange cylinder, a flange plate, and a bottom cylinder. The telescopic cylinder is placed inside the main body of the machine nest, and its fixed end is bolted to the top of the flange cylinder. The telescopic end passes through the top of the flange cylinder and is welded to the inner ring of the flange plate. The top edge of the flange cylinder is bolted to the bottom of the main body of the machine nest. The telescopic end of the telescopic cylinder is bolted to the inner surface of the bottom cylinder through the flange plate. The bottom of the bottom cylinder is bonded to the surface of the anti-slip block.

[0007] Furthermore, the outer diameter of the bottom cylinder is smaller than the inner diameter of the flange cylinder, and they are fitted together.

[0008] Furthermore, the bottom of the anti-slip block is provided with a willow leaf groove, and the side wall is arc-shaped and larger than the bottom ring of the bottom cylinder and the bottom end of the flange cylinder.

[0009] Furthermore, the auxiliary opening and closing assembly includes a slide groove, two sliders, a dual-head motor, two bearing seats, two ball screws, and two ball nuts. The slide groove is formed on the surface of the main body of the machine nest. Two sliders are slidably connected to both ends of the slide groove surface. The surfaces of the two sliders are lower than the surface of the main body of the machine nest and are respectively fixed to the bottom bolts of the two protective covers. The dual-head motor is fixedly installed in the middle section inside the slide groove, and its output shafts at both ends are fixedly connected to the opposite ends of the two ball screws through couplings. The two bearing seats are located at both ends of the dual-head motor and are fixedly installed inside the slide groove by studs. The outer walls of the inner ends of the two ball screws are respectively fixedly connected to the inner rings of the two bearing seats, and the outer walls of the other ends are respectively ball-bearing connected to the two ball nuts. The outer walls of the two ball nuts are respectively fixedly connected to the inner rings of the two sliders.

[0010] Furthermore, the bottom of the protective cover has a connecting plate, the bottom of the connecting plate is bolted to the surface of the slider, and a sealing strip is provided between the two protective covers.

[0011] Furthermore, the outer wall of the main body of the nest is chamfered, and the interior is equipped with a charging module, a communication module, a control module, a locking module, etc., and the surface is connected to the drone through the locking module.

[0012] This utility model has the following beneficial effects: The four leveling components bolted to the four corners of the bottom of the drone's nest provide reliable horizontal adjustment capabilities. In practical applications, different terrains and ground conditions may cause the nest to tilt during placement. The leveling components can flexibly adjust according to the ground conditions to ensure that the nest always remains level. This is crucial for the safe take-off and landing of drones. A stable level surface can effectively prevent collisions or damage to the drone due to unstable attitude during take-off and landing, greatly improving the safety and success rate of drone take-off and landing. At the same time, during drone charging and maintenance, a level nest ensures accurate connection of the charging interface, avoiding safety hazards caused by poor contact. It also facilitates stable parking of the drone within the nest, reducing adverse effects on the fuselage structure and ensuring the normal operation and long service life of the drone.

[0013] The anti-slip block glued to the bottom of the leveling component of this utility model features a willow-leaf groove at the bottom and an arc-shaped design on the sidewalls, which significantly enhances the friction between the anti-slip block and the ground. Under various complex terrain conditions, such as grass and gravel, the anti-slip block effectively prevents the drone nest from sliding, ensuring the nest remains stable during drone takeoff, landing, charging, and other operations.

Detailed Implementation

[0017] The technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments.

[0018] Example:

[0019] Please see Figure 1 , Figure 2 A foldable drone nest includes a nest body 1 and a drone 2 mounted on top of the nest body 1.

[0020] The main body of the nest, 1, forms the skeleton and foundation of the entire nest, and its design needs to balance strength, weight, durability, and foldable portability. The main body of the nest, 1, is manufactured through precision machining or injection molding. Aluminum alloy has a good strength-to-weight ratio and corrosion resistance, making it suitable for outdoor environments; while engineering plastics or composite materials can further reduce weight and provide good impact resistance.

[0021] The basic shape of the nest body 1 is a cuboid structure with an open top, providing sufficient space to accommodate a standard-sized UAV 2. The top surface of the nest body 1, especially the edge areas, is designed with positioning structures and interfaces that match the locking module. These structures ensure that the UAV 2 can land accurately and stably at the predetermined location. Once the UAV 2 is docked, its bottom locking mechanism interacts with the locking module at the top of the nest body 1 to complete both physical locking and electrical connection. This connection method ensures the stability of the UAV within the nest and enables reliable power supply and data exchange.

[0022] The drone 2 is a standardized commercial or customized drone, equipped with a docking mechanism at its bottom that matches the interface at the top of the nest 1, including charging contacts, a communication antenna, a positioning pin, and a locking mechanism. After completing its mission, the drone 2 autonomously flies back and lands in the top opening of the nest body 1. The drone 2 uses existing technology in the field, so it will not be described in detail.

[0023] Please see Figure 1 , Figure 2 , Figure 3 , Figure 4 A foldable drone nest includes a main body 1 with four leveling components 3 bolted to the four corners of the bottom. Four anti-slip blocks 4 are glued to the bottom of each leveling component 3. An auxiliary opening and closing component 5 is bolted to the inner surface of the main body 1. Two protective covers 6 are bolted to both ends of the auxiliary opening and closing component 5. The two protective covers 6 approach each other through the auxiliary opening and closing component 5 and cover the drone 2. The leveling component 3 includes a telescopic cylinder 31, a flange cylinder 32, a flange plate 33, and a bottom cylinder 34. The auxiliary opening and closing component 5 includes a slide 51, two sliders 52, a dual-head motor 53, two shaft seats 54, two ball screws 55, and two ball nuts 56. The bottom of the protective cover 6 has a connecting plate 61.

[0024] The leveling assembly 3 is the core component for achieving horizontal adjustment of the nest. The telescopic cylinder 31 is the main actuator of the leveling assembly 3, providing lifting power. Its fixed end is bolted to the top of the flange cylinder 32, ensuring stable installation inside the nest. The telescopic end of the telescopic cylinder 31 passes through the top of the flange cylinder 32 and is welded to the inner ring of the flange 33, thus transmitting power to the flange 33. The flange cylinder 32 is a cylindrical metal cylinder, its top edge fixed to the bottom of the nest body 1 by bolts. The flange 34 is a flat, circular metal disc, its inner ring welded to the telescopic end of the telescopic cylinder 31, ensuring a rigid connection during movement. The outer ring of the flange 33 is bolted to the inner surface of the bottom cylinder 34, serving to transmit force and provide positioning. The outer diameter of the bottom cylinder 34 is smaller than the inner diameter of the flange cylinder 32; the two are connected by a tight fit. The bottom of the bottom cylinder 34 is fixed with an anti-slip block 4 by adhesive bonding, ensuring sufficient friction when in contact with the ground to prevent slippage. Furthermore, the leveling assembly 3 operates based on the telescopic movement of the telescopic cylinder 31. Through the cooperation of the flange cylinder 32, flange 33, and base cylinder 34, it achieves independent height adjustment of the four corners of the nest bottom, thereby ensuring that the nest remains level. Initial state: When the nest is placed on uneven ground, the four leveling assemblies 3 at the bottom of the nest are at different heights due to the difference in ground height, causing the nest body 1 to tilt. The telescopic cylinder 31 extends and retracts according to the ground tilt, driving the base cylinder 34 and anti-slip block 4 to adjust the height through the flange 33. The flange cylinder 32 serves as a fixed base, ensuring that the telescopic cylinder 31 does not deviate from its original position during movement. The outer diameter of the base cylinder 34 is smaller than the inner diameter of the flange cylinder 32, allowing the base cylinder 34 to move flexibly within the flange cylinder 32. At the same time, the glued anti-slip block 4 contacts the ground, providing stable support. Final state: Through the coordinated adjustment of the four leveling assemblies 3, the nest body 1 can be placed horizontally on different ground surfaces, ensuring that the UAV 2 is in a stable state when landing and being stored.

[0025] The anti-slip block 4 directly affects the contact stability and friction between the machine housing and the ground. The bottom of the anti-slip block 4 has a willow-leaf shaped groove; this groove significantly improves anti-slip performance by increasing the irregularity of the contact surface. The sidewalls of the anti-slip block 4 are curved, a design that not only adapts to different ground shapes but also avoids damage that may be caused by sharp edges. The outer diameter of the anti-slip block 4 is slightly larger than the contact surface between the bottom ring of the base cylinder 34 and the bottom end of the flange cylinder 32, ensuring a tight fit after installation and preventing slippage or lifting.

[0026] The auxiliary opening and closing assembly 5 enables the synchronous and smooth opening and closing of the two protective covers 6. The slide groove 51, the basic track for the auxiliary opening and closing assembly, is located on the inner surface of the housing body 1, providing a guide for the linear motion of the slider 52. The slide groove 51 is designed to have sufficient strength and wear resistance to withstand the reciprocating sliding of the slider 52. The two sliders 52 are slidably connected to both ends of the slide groove 51. The surface of the slider 52 is designed to be lower than the inner surface of the housing body 1, which helps to reduce the space occupied inside the housing when the protective covers 6 are fully open and may also provide some concealment. The slider 52 is fixedly connected to the connecting plate 61 at the bottom of the protective cover 6 by bolts, transmitting its linear motion to the protective cover 6. The dual-head motor 53 is the power source for the entire opening and closing system, fixedly installed in the middle section inside the slide groove 51. Its special feature is that it has output shafts at both ends. When the motor is working, both ends rotate synchronously, providing power to the two ball screws 55. Two bearing seats 54 are located at both ends of the dual-start motor 53 and are fixed to the inner wall of the slide groove 51 by studs. The function of the bearing seats 54 is to support and fix the inner end of the ball screw 55, ensuring that the screw remains stable during rotation and does not experience axial movement or radial runout. The two ball screws 55 are connected to the output shafts at both ends of the dual-start motor 53 via couplings. The couplings ensure precise coaxial transmission between the motor output shaft and the screw, reducing vibration and wear. The ball screw 55 is a high-efficiency transmission element that converts the rotational motion of the motor into the linear motion of the slider 52. Its inner end is fixed by the bearing seat 54, and its outer end extends to the area where the slider 52 is located. Two ball nuts 56 are respectively connected to the outer ends of the two ball screws 55 by ball bearings. When the ball screw 55 rotates, the ball nuts 56 move along the thread direction of the screw. The outer wall of the ball nut 56 is fixedly connected to the inner ring of the slider 52, so the movement of the ball nut 56 directly drives the slider 52 to move along the groove 51. Opening process: When the UAV 2 needs to take off or undergo maintenance, the control system issues a command. The dual-head motor 53 begins to rotate forward. The output shafts at both ends of the motor drive two ball screws 55 to rotate synchronously in opposite directions via couplings, for example, one clockwise and the other counterclockwise, depending on the thread direction design of the screws. The rotation of the ball screws 55 drives the connected ball nut 56 to move in the opposite direction. The movement of the ball nut 56, in turn, drives the slider 52 fixed to it to slide within the groove 51. Since the two sliders 52 are respectively connected to the bottom ends of the two protective covers 6, the relative or opposite movement of the sliders 52 depends on the specific design. Here, it is described as facing each other to achieve closure, while the reverse rotation of the motor achieves opening, causing the two protective covers 6 to move away from each other, thus opening and exposing the UAV 2. Closing process: When the UAV 2 lands and needs to be protected, the control system issues a closing command.The dual-head motor 53 rotates in opposite directions, the ball screw 55 rotates in opposite directions accordingly, the ball nut 56 moves in the opposite direction, driving the slider 52 to slide towards the middle of the groove 51, thereby driving the two protective covers 6 to move closer to each other until they completely cover the drone 2.

[0027] The protective cover 6 is the component that directly covers and protects the drone 2 within the housing. The protective cover 6 is designed as two semi-enclosed shell structures, the shape of which can be customized according to the size and shape of the drone 2. The connecting plate 61 is a connecting structure integrated into the bottom of the protective cover 6. It extends from the bottom of the protective cover 6, forming a flat area. The design of the connecting plate 61 not only provides a direct and secure mounting base for the slider 52, but also requires a sealing strip between the two protective covers 6 when they approach and eventually close. The sealing strip is typically installed on the outer edge of one of the protective covers 6, or grooves are provided on the corresponding edges of both protective covers 6 to embed the sealing strip. The sealing strip is commonly made of silicone or rubber, which has good elasticity and aging resistance. Its function is to fill the gap between the two protective covers 6 when they are closed, forming an effective seal, further improving the protection level and preventing moisture and dust from entering from the joint.

[0028] It should be noted that the specific models and specifications of the main body 1, the drone 2, the telescopic cylinder 31, and the dual-head motor 53 need to be selected and determined according to the actual specifications of the device. The specific selection and calculation method adopts the existing technology in this field, so it will not be described in detail.

[0029] The power supply and operating principle of the main body 1, the drone 2, the telescopic cylinder 31, and the dual-head motor 53 are clear to those skilled in the art and will not be described in detail here.

Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this application is defined by the appended claims rather than the foregoing description.
