Description

Technical Field

[0001] The utility model belongs to the technical field of unmanned aerial vehicles, in particular to a multi-layered unmanned aerial vehicle nest. Background Art

[0002] With the continuous development of drones, drones have begun to be widely used in various fields and industries. Among them, vehicle-mounted drones are gradually becoming the next development direction of automotive technology because they are easy to use with cars and have strong maneuverability. However, the traditional way of using drones with vehicles is mostly to land the drone on the roof, and the personnel go up to the roof and manually place the drone into the roof storage equipment; or after the drone lands near the car, the personnel move the drone from the ground to the car for storage. Therefore, in actual application, there are situations where drones are inconvenient to take off and land.

[0003] The following problems exist during the use of the above-mentioned drones:

[0004] (1) The equipment has a low degree of automation, too much human intervention, and low efficiency;

[0005] (2) Insufficient use of roof space;

[0006] (3) In the prior art, after a drone is stored, the same problem also exists when the drone is released again, that is, the drone needs to be placed manually and a long period of preparation is required before the drone can be flown. The entire process of storing and releasing the drone is extremely cumbersome, which greatly reduces work efficiency.

[0007] In response to the above technical problems, there are studies on multi-layer drone nests in the prior art, such as the invention patent application with publication number CN113247288 A and name Drawer-type drone nest, which discloses a drawer-type drone nest that is overlapped up and down and can be rotated to open.

[0008] However, the inventors found that when drones are used on vehicles, they are often located in remote areas where the road conditions and road levels cannot be ensured. If the rotating and opened drone nest cannot be well positioned, it may cause certain interference to the drone during takeoff or landing. At the same time, during the transportation of the vehicle-mounted drone nest, when encountering rugged road conditions, the up and down vibrations pose a certain risk of damage to the drone. Utility Model Content

[0009] The purpose of the utility model is to provide a multi-layer drone nest, which can be well adapted to the transportation process of the drone and alleviate the vibration when the road is rugged. At the same time, when the drone's containment shell is rotated and opened, the abutment between the brake rod and the inner rod is used to lock and position the containment shell, preventing the movement of the containment shell from interfering with the take-off and landing of the drone, thereby solving the problems in the prior art.

[0010] In order to solve the above technical problems, the utility model is realized by the following technical solutions:

[0011] The utility model is a multi-layer drone nest, comprising an installation box, one side of which is provided with an inner rod, and the upper part of the installation box is provided with a multi-layer accommodating shell, each of which is rotatably connected to the installation box; a double-head locking motor is provided on the bottom wall of each accommodating shell, the first output end of the double-head locking motor is connected to a first screw, the first screw is rotatably connected to a first nut, the first nut is connected to a brake rod, and the brake rod is arranged toward the inner rod.

[0015] Optionally, a bracket is further provided in the installation box, and a plurality of rubber shock-absorbing tubes are provided on the bracket, and the top of the rubber shock-absorbing tubes is in contact with the top wall of the installation box.

[0016] Optionally, the rubber shock-absorbing cylinder includes a cylindrical body, a bulging portion is provided in the middle of the cylindrical body, and the bulging portion is bulged outward.

[0017] Optionally, an inner sleeve is sleeved on the inner rod, an outer sleeve is sleeved on the outside of the inner sleeve, and the inner sleeve and the outer sleeve are respectively connected to different accommodating shells; the inner sleeve and the inner rod, and the outer sleeve and the inner sleeve are all rotationally connected, a drive motor is arranged in the installation box, and the output end of the drive motor is connected to the inner sleeve through a transmission device.

[0018] Optionally, an arc-shaped slideway is provided on the inner wall of the outer sleeve, and a slider is provided on the outer wall of the inner sleeve, and the slider is adapted to the arc-shaped slideway.

[0021] The utility model has the following beneficial effects:

[0022] 1. The utility model provides a multi-layered drone nest. When the drone's housing shell is rotated and opened, the housing shell is locked and positioned by abutting against the brake rod and the inner rod, thereby preventing the housing shell from moving and interfering with the drone's take-off and landing, thereby ensuring the drone's smooth take-off and landing.

[0023] 2. The utility model utilizes positive and negative threaded screws to achieve the two abutting parts approaching or moving away from each other. The limiting claws on the top of the abutting parts are compatible with the landing gear of the UAV, thereby limiting or releasing the limit of the UAV, facilitating the safe transportation of the UAV.

[0024] 3. By setting a rubber shock-absorbing tube in the installation box, the rubber shock-absorbing tube can be fully utilized to alleviate the vibration during the process of vibration being transmitted from the base to the installation box. This can well adapt to the transportation process of the drone and alleviate the vibration when the road is rugged.

[0025] 4. When the vehicle is moving, under the action of the rubber shock absorber, the shock absorber will expand and contract up and down when it bumps up and down, thereby achieving shock absorption. When it vibrates laterally, the rubber shock absorber will bend laterally, thereby achieving lateral shock absorption movement. The rubber material of the rubber cylinder will convert part of the mechanical energy into heat energy when vibrating, thereby consuming the vibration energy and playing a shock absorption role.

[0026] Of course, any product implementing the present invention does not necessarily need to achieve all of the advantages described above at the same time. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0034] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0035] Embodiment 1:

[0036] See also Figure 1 As shown, the utility model is a multi-layer drone nest, including an installation box 1, an inner rod 2 is arranged on one side of the installation box 1, and a multi-layer accommodating shell 3 is arranged on the upper part of the installation box 1, and each of the accommodating shells 3 is rotatably connected to the installation box 1; a double-head locking motor 4 is arranged on the bottom wall of each accommodating shell 3, and a first output end of the double-head locking motor 4 is connected to a first screw 26, and a first nut 27 is rotatably connected to the first screw 26, and a brake rod 5 is connected to the first nut 27, and the brake rod 5 is arranged toward the inner rod 2.

[0037] In this embodiment, the brake rod 5 is used to abut or release the abutment with the inner rod 2. When the two are in abutment, the position of the accommodating shell 3 can be limited to prevent it from displacement or shaking; when the two are released from abutment, the accommodating shell 3 can be stored or opened under the drive of the driving motor 16.

[0038] The multi-layered drone nest proposed in this embodiment can be used in conjunction with a vehicle and is vehicle-mounted. Considering the use environment of the drone, the vehicle parking position may be not level, and the limit of the brake lever 5 can easily solve this problem, ensuring that the drone takes off and lands smoothly. In addition, the multi-layered driven rotating open cabin structure of this embodiment can ensure that multiple drones take off or land at the same time, improving space utilization and automation, and facilitating storage and transportation.

[0039] In order to effectively limit the position of the drone during transportation, this embodiment also proposes an expandable drone clamping and fixing structure:

[0040] The second output end of the double-head locking motor 4 is connected to a forward and reverse thread screw 6, which includes a forward thread segment and a reverse thread segment, and the forward thread segment and the reverse thread segment are respectively rotatably connected with a forward nut and a reverse nut, and the forward nut and the reverse nut are respectively connected with abutment portions 7. In this way, the forward and reverse thread screws 6 can be rotated to drive the forward nut and the reverse nut to approach or move away from each other, so that the two abutment portions 7 can be moved closer or farther from each other, and the drone can be limited.

[0041] In order to facilitate the contact between the abutting portion 7 and the drone, a sliding groove 8 is provided at the center of the bottom of each of the accommodating shells 3, and the abutting portion 7 passes through the sliding groove 8. A limiting claw 9 is provided at the top of the abutting portion 7, and the shape of the limiting claw 9 is adapted to the landing gear of the drone.

[0042] In this embodiment, an arc-shaped groove is arranged on the outer side of the limiting claw 9, and the arc-shaped groove can well cooperate with the rod body of the landing gear to achieve more effective limiting.

[0043] Taking into account the bumpy road conditions that may occur during transportation, in order to reduce the impact of vibration on the drone, a bracket 10 is further provided in the installation box 1 of this embodiment, and a plurality of rubber shock-absorbing tubes 11 are provided on the bracket 10, and the top of the rubber shock-absorbing tube 11 is in contact with the top wall of the installation box 1; a base 22 is connected to the bottom of the installation box 1, and the base 22 is connected to the bracket 10 in the installation box 1.

[0044] During installation, the base 22 is fixed to the set position of the vehicle, and when vibration occurs, the vibration degree is reduced by the shock absorbing effect of the rubber shock absorbing tube 11. The rubber shock absorbing tube 11 is made of rubber material.

[0045] like Figure 1 , Figure 4As shown, the rubber shock-absorbing cylinder 11 includes a cylindrical body 12, and a bulging portion 13 is provided in the middle of the cylindrical body 12, and the bulging portion 13 is provided to protrude outward. When the vehicle moves, under the action of the rubber shock-absorbing cylinder 11, the shock-absorbing cylinder will expand and contract up and down when bumping up and down, thereby achieving shock absorption. When vibrating laterally, the rubber shock-absorbing cylinder 11 bends laterally, thereby playing a lateral shock-absorbing movement. The rubber material of the rubber cylinder will convert part of the mechanical energy into heat energy when vibrating, thereby consuming the vibration energy and playing a shock-absorbing role.

[0046] When the rubber shock absorbing tube 11 is pressed downward by pressure, the middle protruding structure of the rubber shock absorbing tube 11 continues to bulge outward under the pressure, thereby playing a buffering role.

[0047] In actual use, multiple drones are usually required to work together. The multi-layer drone nest of this embodiment can improve space utilization, solve the problem that a single-layer structure is not convenient for accommodating multiple drones, and realize the simultaneous take-off and landing of multiple drones.

[0048] like Figure 3 As shown, the multi-layer containment shell 3 is rotated and opened in place. In this embodiment, two layers of containment shells 3 are provided, namely, an upper containment shell 233 and a lower containment shell 243. When rotated in place, the upper containment shell 233, the lower containment shell 243 and the cover 21 are all opened, so that multiple drones can take off and land simultaneously.

[0049] In the specific implementation, Figure 2 As shown, in this embodiment, an inner sleeve 14 is sleeved on the inner rod 2, and an outer sleeve 15 is sleeved on the outside of the inner sleeve 14. The inner sleeve 14 and the outer sleeve 15 are respectively connected to different containing shells 3; in this embodiment, the inner sleeve 14 is connected to the upper containing shell 233, and the outer sleeve 15 is connected to the lower containing shell 243.

[0050] The inner sleeve 14 and the inner rod 2, and the outer sleeve 15 and the inner sleeve 14 are all rotatably connected. A driving motor 16 is provided in the installation box 1, and the output end of the driving motor 16 is connected to the inner sleeve 14 through a transmission device. An arc-shaped slideway 19 is provided on the inner wall of the outer sleeve 15, and a slider 20 is provided on the outer wall of the inner sleeve 14, and the slider 20 is adapted to the arc-shaped slideway 19. A cover plate 21 is provided on the top of the inner rod 2, and the cover plate 21 is adapted to the shape of the accommodating shell 3.

[0051] The angle corresponding to the arc slide 19 of this embodiment is 120 degrees. In the starting position, the slider 20 is located at one end of the arc slide 19. When the drive motor 16 is running, the drive motor 16 drives the slider 20 to slide in the arc slide 19, thereby driving the upper containment shell 233 to rotate. At this time, the inner sleeve 14 rotates, while the outer sleeve 15 does not rotate, and relative rotation occurs between the inner sleeve 14 and the outer sleeve 15; when the slider 20 rotates 120 degrees to the other end of the arc slide 19, the inner sleeve 14 no longer rotates relative to the outer sleeve 15, but the inner sleeve 14 drives the outer sleeve 15 to rotate together. After rotating 120 degrees again, the inner sleeve 14 and the outer sleeve 15 stop rotating. The final position relationship is as follows: Figure 3 shown.

[0052] When the inner sleeve 14 and the outer sleeve 15 stop rotating, the first lead screw 26 in the double-head locking motor 4 rotates, the first lead screw 26 is connected to the first nut 27, and the first nut 27 is connected to the brake rod 5, so that the brake rod 5 extends toward the inner rod 2 until the end of the brake rod 5 abuts against the inner rod 2, thereby achieving the effect of locking the position of each accommodating shell 3. When the drone lands, similarly, the first lead screw 26 is used to drive the brake rod 5 to move toward the inner rod 2, and the position lock of each accommodating shell 3 can be released.

[0053] The transmission mechanism in this embodiment is a worm gear 18 and worm 17 transmission device:

[0054] The driving motor 16 drives the worm 17 to rotate, and the worm 17 is meshed with the worm wheel 18, thereby driving the worm wheel 18 to rotate. The worm wheel 18 is connected to the inner sleeve 14, thereby driving the inner sleeve 14 to rotate.

[0055] Working principle:

[0056] A bracket 10 is embedded in the lower part of the installation box 1, a base 22 is installed at the lower end of the bracket 10, a rubber shock-absorbing tube 11 is installed at the upper end of the bracket 10, and the rubber shock-absorbing tube 11 is a cylindrical structure with the middle part protruding outward. A double-layer sleeve structure is rotatably installed on the installation box 1, an inner sleeve 14 is rotatably inserted in the outer sleeve 15, an inner rod 2 is rotatably inserted on the innermost side of the inner sleeve 14, the upper end of the inner rod 2 is connected to the cover plate 21, and a multi-layer containing shell 3 is attached to the lower part of the cover plate 21, and the multi-layer containing shell 3 is fixedly connected to the multi-layer sleeve respectively, and the lower end of the inner rod 2 is fixedly installed in the installation box 1.

[0057] A slider 20 is installed at the lower part of the inner sleeve 14, and an arc-shaped slideway 19 is opened on the inner side of the lower part of the outer sleeve 15 located outside. The angle range of the arc-shaped slideway 19 is 120 degrees. A worm gear 18 is set at the lower end of the inner sleeve 14. A worm 17 is engaged with the worm gear 18. The worm 17 is connected to the output end of the drive motor 16, and the drive motor 16 is fixedly installed on the installation box 1. A first lead screw 26 is connected to one output end of the double-head locking motor 4. A first nut 27 is engaged with the first lead screw 26. A brake rod 5 is installed on the first nut 27. The brake rod 5 passes through the accommodating shell 3 and is arranged toward the inner rod 2.

[0058] By installing the base 22 of the device on the luggage rack or in the compartment of the vehicle, the driving motor 16 drives the worm 17, and then drives the worm wheel 18 to rotate, the rotation of the worm wheel 18 drives the inner sleeve 14 inside to rotate, and the rotation of the inner sleeve 14 drives the upper accommodating shell 3 to rotate. When the upper accommodating shell 3 rotates 120 degrees counterclockwise, the slider 20 contacts the other end of the arc slide 19, and then drives the outer sleeve 15 outside to rotate. When the upper accommodating shell 3 rotates 240 degrees, the driving motor 16 stops rotating.

[0059] At the same time, the double-head locking motor 4 rotates to unlock the limit claw 9 and the abutment part 7, and at the same time drives the first nut 27 on the first screw 26 to produce linear movement. The movement of the first nut 27 drives the brake rod 5 to contact the inner rod 2, thereby locking the rotation angle of the inner sleeve 14 and the outer sleeve 15.

[0060] When the drone is landing, the drone lands in the housing 3, and then the double-head locking motor 4 is actuated to drive the limit claws 9 to expand outward, thereby clamping and fixing the landing gear of the drone body 25, thereby increasing the stability of the drone during transportation.

[0061] The multi-layer structure of the device increases space utilization, can store multiple drones, and can realize the take-off and landing of multiple drones at the same time.
