Description

Technical Field

[0001] This utility model belongs to the field of unmanned aerial vehicle (UAV) technology, and in particular relates to a UAV positioning device and a UAV take-off and landing nest. Background Technology

[0002] Currently, for consumer-grade drones, such as quadcopter drones, take-off and landing are mostly done directly from the ground. Of course, there are also portable take-off and landing platforms using similar folding table-like structures, but their automation level is not high and their operability is not strong. Of course, the take-off and landing platform disclosed in document number CN118419309A "UAV Take-off and Landing Platform" has flight capabilities and can dock drones in the air, but its structure is complex, and the technical difficulty of docking the take-off and landing platform with drones in the air is even greater, which may lead to the risk of drone crash. The take-off and landing device disclosed in document number CN109353536A "UAV Take-off and Landing Device and Automobile" can provide take-off and landing for drones and store drones. Its lifting plate is used for take-off and landing of drones, and the lifting plate has a receiving slot for drones to fall into. However, it has high requirements for the accuracy of drone take-off and landing. If the drone is misaligned on the lifting plate, the lifting plate is very likely to be squeezed and damaged by the top plate during the ascent or descent. Utility Model Content

[0003] In order to solve the above-mentioned technical problems, the purpose of this utility model is to provide a drone positioning device with a simple structure that enables drones to take off and land conveniently, and can automatically store the drone in the seat.

[0004] To achieve the above objectives, the technical solution of this utility model is as follows: A drone positioning device includes a base, a landing plate, and a lifting drive component. The upper end of the base is recessed with a positioning hole. The lifting drive component is vertically installed in the positioning hole. The landing plate is horizontally arranged, and the lower end of the landing plate is connected to the lifting end of the lifting drive component. The lifting drive component drives the landing plate to rise outside the positioning hole or descend into the positioning hole. The landing plate is used for drone take-off and landing.

[0005] The beneficial effects of the above technical solution are as follows: when the drone takes off and lands, the lifting drive component drives the landing plate to rise above the positioning hole, at which time the drone can take off and land conveniently on the landing plate. After the drone lands, the lifting drive component can retract to lower the landing plate into the positioning hole, so that the drone can also be accommodated in the positioning hole.

[0006] In the above technical solution, the positioning hole is a countersunk hole with its thick end facing upward. The lifting drive is installed in the thin end of the positioning hole. The lifting drive drives the lifting plate to rise outside the positioning hole or to descend into the thick end of the positioning hole.

[0007] The beneficial effect of the above technical solution is that the narrow end of the positioning hole is used to accommodate the lifting drive component, while the wide end of the positioning hole is used to accommodate the landing plate and the drone.

[0008] In the above technical solution, the upper end of the base body is provided with a plurality of rotor grooves circumferentially spaced around the edge of the positioning hole, and each rotor groove is recessed with a connecting groove near the positioning hole. The rotor groove and the positioning hole are connected through the connecting groove. The rotor groove and the corresponding connecting groove are used to accommodate the rotor and rotor arm of the UAV.

[0009] The beneficial effects of the above technical solution are as follows: the thick end of the positioning hole is used to accommodate the landing plate and the main body of the UAV, while the rotor slot and the corresponding connecting slot are used together to accommodate the corresponding rotor and rotor arm of the UAV. This allows the UAV to be stored on the seat after landing, and the positioning hole, connecting slot and rotor slot together limit the movement of the UAV.

[0010] The above technical solution also includes a rotary drive component, which is installed at the lifting end of the lifting drive component. The lifting plate is installed at the driving end of the rotary drive component. The lifting drive component is used to drive the rotary drive component to lift the lifting plate up and down, and the rotary drive component is used to drive the lifting plate to rotate horizontally.

[0011] The beneficial effect of the above technical solution is that when the UAV lands on the landing board, the landing board can be driven to rotate horizontally by the rotary drive component so that the multiple rotors can be aligned with their respective rotor slots.

[0012] The rotor groove described in the above technical solution is frustoconical in shape, with its thicker end facing upwards.

[0013] The beneficial effect of the above technical solution is that when the UAV descends with the landing plate, the rotor of the UAV lands in the rotor slot, and at this time the frustum-shaped rotor slot can guide the rotor to the center within the rotor slot.

[0014] The lifting drive component described in the above technical solution is a telescopic electric cylinder.

[0015] The advantages of the above technical solution are that it has a simple structure and is easy to control.

[0016] The rotary drive component described in the above technical solution is an electric rotary table.

[0017] The advantages of the above technical solution are that it has a simple structure and is easy to control.

[0018] The above technical solution also includes a controller and a power module disposed in the seat body, and the lifting drive, the rotating drive and the controller are all electrically connected to the power module.

[0019] The beneficial effect of the above technical solution is that it enables the entire UAV positioning device to be flexibly moved and highly adaptable.

[0020] In the above technical solution, a first photoelectric sensor is provided in the middle of the upper part of the landing plate, and a second photoelectric sensor is provided in the middle of the bottom wall of each rotor slot. The first photoelectric sensor and multiple second photoelectric sensors are electrically connected to the controller. The sensing ends of the first photoelectric sensor and multiple second photoelectric sensors are all facing upward, and are used to sense whether the multiple rotors of the UAV landing on the landing plate are aligned with the corresponding rotor slots.

[0021] The beneficial effects of the above technical solution are: its structure is simple, so that the first photoelectric sensor and multiple second photoelectric sensors can jointly monitor the position of the UAV on the landing plate. Only when the multiple rotors of the UAV are aligned with the multiple rotor slots can the lifting drive be lowered so that the UAV can be better accommodated in the receiving cavity composed of positioning holes, rotor slots and connecting slots.

[0022] The second objective of this invention is to provide a drone take-off and landing nest with a simple structure that can be used for drone take-off and landing.

Detailed Implementation

[0034] The principles and features of this utility model are described below with reference to the accompanying drawings. The examples given are for illustrative purposes only and are not intended to limit the scope of this utility model. The utility model is described more specifically in the following paragraphs by way of example with reference to the accompanying drawings. The advantages and features of this utility model will become clearer from the following description and claims. It should be noted that the drawings are all in a very simplified form and use non-precise proportions, and are only used to facilitate and clarify the illustration of the embodiments of this utility model.

[0035] Example 1

[0036] like Figure 1As shown, this embodiment provides a drone positioning device, including a base 1, a landing plate 2, and a lifting drive 3. The upper end of the base 1 has a recessed positioning hole 11. The lifting drive 3 is vertically installed in the positioning hole 11. The landing plate 2 is horizontally arranged, and the lower end of the landing plate 2 is connected to the lifting end of the lifting drive 3. The lifting drive 3 drives the landing plate 2 to rise outside the positioning hole 11 or to descend into the positioning hole 11. The landing plate 2 is used for drone take-off and landing. When the drone takes off or lands, the lifting drive drives the landing plate to rise above the positioning hole, allowing the drone to take off and land conveniently on the landing plate. After the drone lands, the lifting drive retracts to lower the landing plate into the positioning hole, allowing the drone to also be accommodated in the positioning hole.

[0037] like Figure 2 As shown, in the above technical solution, the positioning hole 11 is a countersunk hole with its thick end facing upward. The lifting drive 3 is installed in the thin end of the positioning hole 11. The lifting drive 3 drives the landing plate 2 to rise outside the positioning hole 11 or descend into the thick end of the positioning hole 11. In this way, the thin end of the positioning hole is used to accommodate the lifting drive, while the thick end of the positioning hole is used to accommodate the landing plate and the drone.

[0038] like Figure 1 and Figure 2 As shown in the above technical solution, the upper end of the base 1 is provided with a plurality of rotor grooves 12 arranged circumferentially around the edge of the positioning hole 11, and each rotor groove 12 is recessed with a connecting groove 13 near the positioning hole 11. The rotor groove 12 and the positioning hole 11 are connected through the connecting groove 13. The rotor groove 12 and the corresponding connecting groove 13 are used to accommodate the rotor and rotor arm of the UAV. In this way, the thick end of the positioning hole is used to accommodate the landing plate and the main body of the UAV, while the rotor groove and the corresponding connecting groove are used together to accommodate the rotor and rotor arm of the UAV. This allows the UAV to be stored on the base after landing, and the positioning hole, the connecting groove and the rotor groove together limit the position of the UAV.

[0039] like Figure 2 and Figure 3 As shown, the above technical solution also includes a rotary drive component 4, which is installed at the lifting end of the lifting drive component 3. The landing plate 2 is installed at the driving end of the rotary drive component 4. The lifting drive component 3 is used to drive the rotary drive component 4 to lift the landing plate 2. The rotary drive component 4 is used to drive the landing plate 2 to rotate horizontally. This allows the landing plate to rotate horizontally when the UAV lands on the landing plate, so that multiple rotors can be aligned with their corresponding rotor slots.

[0040] like Figure 2 and Figure 3 As shown, the rotor groove 12 in the above technical solution is truncated cone-shaped with its thick end facing upward. This allows the rotor of the UAV to be guided to the center of the rotor when it lands in the rotor groove as the UAV descends with the landing plate.

[0041] like Figure 2 and Figure 3 As shown, the lifting drive component 3 in the above technical solution is a telescopic electric cylinder. Preferably, the rotating drive component 4 is an electric rotary table, which has a simple structure and is easy to control (in this embodiment, the lifting drive component and the rotating drive component can be combined to form a two-degree-of-freedom drive component, which has lifting and rotating functions).

[0042] like Figure 2 and Figure 3 As shown, the above technical solution also includes a controller 5 and a power module 6 disposed within the base 1. The lifting drive 3, the rotation drive 4, and the controller 5 are all electrically connected to the power module 6, thus enabling the entire UAV positioning device to be flexibly moved and highly adaptable. In this embodiment, a mounting cavity can also be provided within the base, where the power module and the controller can be installed. The power module can be a lithium battery, and the controller can be an ARM series microcontroller. In this embodiment, a charging port electrically connected to the power module 6 can also be provided at the upper end of the base.

[0043] like Figures 1-3 As shown in the above technical solution, a first photoelectric sensor 7a is provided in the middle of the upper end of the landing plate 2, and a second photoelectric sensor 7b is provided in the middle of the bottom wall of each rotor slot 12. The first photoelectric sensor 7a and the multiple second photoelectric sensors 7b are all electrically connected to the controller 5. The sensing ends of the first photoelectric sensor 7a and the multiple second photoelectric sensors 7b are all facing upwards. They are used to sense whether the multiple rotors of the UAV landing on the landing plate 2 are aligned with the corresponding rotor slots 12. The structure is simple. In this way, the first photoelectric sensor and the multiple second photoelectric sensors can jointly monitor the position of the UAV on the landing plate. Only when the multiple rotors of the UAV are aligned with the multiple rotor slots can the lifting drive be lowered so that the UAV can be better accommodated in the accommodating cavity composed of positioning holes, rotor slots and connecting slots.

[0044] In this embodiment, four rotor slots and four connecting slots are provided, so that the UAV positioning device can meet the take-off and landing requirements of the matching quadcopter UAV.

[0045] In this embodiment, the base can be made of lightweight plastic.

[0046] In this embodiment, both the first and second photoelectric sensors can be infrared ranging probes (an obstacle within 20cm above them can be considered as generating a sensing signal). When the drone is landing, if the first photoelectric sensor detects a signal at the top of the landing plate, it can be considered that the drone has successfully landed on the landing plate. If any of the second photoelectric sensors does not detect a signal, it can be considered that there is a circumferential misalignment when the drone lands on the landing plate, that is, multiple rotors are not aligned with multiple rotor slots. This requires the rotation drive to rotate the landing plate so that each rotor of the drone is aligned with the corresponding rotor slot (at this time, the first photoelectric sensor detects a signal, multiple second photoelectric sensors detect a signal, and multiple third photoelectric sensors do not detect a signal). Then, the lifting drive will drive the landing plate downward so that the drone falls into the receiving cavity.

[0047] In this embodiment, the rotation angle of the rotary drive can be limited to within ±180°, which can avoid the problem of wire tangling in the first photoelectric sensor on the landing plate.

[0048] Example 2

[0049] like Figures 4-7 As shown, this embodiment provides a drone take-off and landing nest, including a shell 200 and a drone positioning device 100 as described in Embodiment 1. The shell 200 includes a housing 210 and a cover 220. The upper end of the housing 210 is open, and the cover 220 is installed at the opening of the housing 210. The cover 220 is used to open or close the opening of the housing 210. The base 1 is embedded in the housing 210. Its structure is simple and enables the drone take-off and landing nest to provide better take-off and landing for drones. In this embodiment, two covers 220 can be provided. The two covers 220 are rotatably or slidably disposed at the opening of the housing 210, and the covers have a drive member 230 for driving them to open or close. At this time, a vehicle roof rack can be integrated under the shell, and the shell can be installed on the roof of an SUV through the vehicle roof rack.

[0050] like Figure 4 and Figure 5 As shown, when the cover is rotatably mounted at the opening of the housing 210, a joint motor (i.e., a drive component 230) can be installed at the rotatable connection between the cover and the housing. At this time, the cover rotates to open under the drive of the corresponding drive component. This is when the two covers are configured to open opposite each other. Figures 6-8As shown, when the cover is slidably installed at the opening of the housing 210, the cover and the upper end of the housing are slidably connected. The two covers slide close to each other to close the housing 210, and the two covers slide away from each other to open the opening of the housing 210. The driving component can be a telescopic electric cylinder (i.e., driving component 230, which is set against the wall inside the housing so that the driving component does not occupy the space above the seat). At this time, the two driving components are horizontally installed on one side inside the housing, and their telescopic ends are opposite to each other and are respectively connected to the corresponding cover. At this time, the two driving components retract synchronously to drive the two covers to slide close to each other, and the two driving components extend synchronously to drive the two covers to slide away from each other.

[0051] In this embodiment, the controller can also be connected to a smartphone via a wireless communication module. In this case, the operating status of the drone positioning device can be controlled by the APP on the mobile phone, while the drone is remotely controlled by its matching control terminal.

[0052] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model in any way. Those skilled in the art can readily implement this utility model based on the accompanying drawings and the above description. However, any modifications, alterations, or equivalent variations made by those skilled in the art without departing from the scope of the utility model's technical solution, utilizing the disclosed technical content, are considered equivalent embodiments of this utility model. Furthermore, any equivalent changes, alterations, or variations made to the above embodiments based on the essential technology of this utility model are still within the protection scope of this utility model's technical solution.
