Description

Technical Field

[0001] This invention relates to smart light pole technology, specifically a smart light pole with a mechanism for charging drones. Background Technology

[0002] As is widely known, with the rapid development of the low-altitude economy, drone applications in cities are becoming increasingly common, such as agricultural spraying and food delivery—applications distinct from photography. However, limited battery life, insufficient communication coverage, and reliance on manual takeoff and landing hinder large-scale application. Existing drone hangars are mostly independently constructed, resulting in high deployment costs and low resource reuse rates. Combining hangars with smart streetlights can effectively reduce redundant infrastructure investment and improve drone operational efficiency and coverage.

[0003] For example, the invention patent with application publication number CN113844658A, application publication date of December 28, 2021, and title "A Logistics Delivery Drone".

[0004] For example, the invention patent with application publication number CN110979704B, application publication date August 20, 2021, and title "A Logistics Delivery Drone".

[0005] The shortcoming of existing technology is that when a light pole is combined with a drone hangar, the hangar is usually set on the top of the light pole as a take-off and landing platform for the drone. When the drone needs to charge and return to the hangar, it will land. Especially during landing, the impact generated by the drone and the airflow from the rotating rotor will bring dynamic load (small sway) to the light pole structure. As a slender structure, the fatigue strength of the light pole structure will be greatly tested during long-term use. Summary of the Invention

[0006] The purpose of this invention is to provide a smart light pole with a mechanism for charging drones, in order to overcome the aforementioned shortcomings in the prior art.

[0007] To achieve the above objectives, the present invention provides the following technical solution: a smart light pole with a charging mechanism for drones, comprising a light pole and a drone. The top of the light pole is respectively provided with an LED light frame and a platform hangar for supporting the drone. The platform hangar includes a shell with an upper opening. The shell is provided with a tensioned integral frame for supporting the drone. The tensioned integral frame includes two parallel planar frames. The planar frames are provided with protruding frames. The two protruding frames are arranged alternately and oppositely. A central load-bearing rope is provided between the tops of the two protruding frames. An outer pull rope is provided between the two planar frames along the diagonal.

[0008] As a further description of the above technical solution: a guide frame is provided on the planar frame, and a four-sided pyramidal groove is opened on the guide frame; a guide frame corresponding to the guide frame is provided at the bottom of the UAV.

[0009] As a further description of the above technical solution: a limiting plate is slidably connected to the shell, and the limiting plate is driven to slide between the two planar frames to restrict them, thereby locking the tensioning frame.

[0010] As a further description of the above technical solution: a rotating ring is rotatably connected to the bottom of the housing, and a limiting protrusion is provided on the rotating ring. The limiting plate is attached to the inner wall of the rotating ring to limit the degree of freedom of the tensioning frame, and the limiting plate is attached to the limiting protrusion to lock the tensioning frame.

[0011] As a further description of the above technical solution: a pushing drive source is provided at the bottom of the housing, and an extension plate corresponding to the pushing drive source is provided on the rotating ring. The pushing drive source pushes against the extension plate to drive the rotating ring to rotate.

[0012] As a further description of the above technical solution: a cable for pulling the housing is provided inside the lamp post, and flip-over cover plates are symmetrically rotatably connected to the housing, and the two flip-over cover plates are driven to flip over and cover the housing.

[0013] As a further description of the above technical solution: the lamp post is provided with a side limiting frame for a clamp flip cover plate, the flip cover plate is provided with an arc-shaped block, and the housing moves with the pull cable so that the flip cover plate opens and closes along the side limiting frame.

[0014] As a further description of the above technical solution: the side limiting frame includes a concave frame corresponding to the flip cover and a sealing head disposed on the lamp post, wherein the sealing head is provided with a central tube for the concave frame to slide.

[0015] As a further description of the above technical solution: steel balls are respectively provided at both ends of the central load-bearing rope, and the two steel balls are rotatably connected to the holes opened on the convex frame.

[0016] As a further description of the above technical solution: the lamp post is equipped with a tensioning wheel for winding the cable, and the tensioning wheel is driven by a traction motor on the lamp post.

[0017] In the above technical solution, the present invention provides a smart light pole with a charging mechanism for drones, which has the following beneficial effects: when landing, it contacts the top flat frame, and because the tension structure flat frame will sway with the impact of the drone's own weight and the rotor airflow, it buffers the dynamic load when the drone lands, protects the slender light pole structure, and compared with heavy metal springs and bulky vibration-absorbing sponges, the overall tension frame is used for buffering, which is suitable for the top of slender light poles.

Detailed Implementation

[0021] To enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings.

[0022] Please see Figure 1-10 This invention provides a technical solution: a smart light pole with a charging mechanism for drones, comprising a light pole 1 and a drone. The top of the light pole 1 is respectively provided with an LED light frame 3 and a platform hangar 2 for carrying the drone. The LED light frame 3 includes a bracket 32 ​​welded to the light pole 1, and an LED light head 31 is provided on the bracket 32. Figure 1 and Figure 2 As shown, the platform hangar 2 includes a lower shell 21 and an upper shell 22 fixedly connected by screws and nuts. The upper shell 22 has an open top design for the landing of drones. The lower shell 21 is equipped with a tensioned integral frame 41 for supporting the drones. The tensioned integral frame 41 includes two parallel planar frames 411, one of which is located at the bottom of the lower shell 21. Both planar frames 411 are welded with protruding frames 412, which are staggered and opposite to each other. Figure 3 and Figure 5 As shown, both convex frames 412 are hollow frames that interlock with each other. A central load-bearing rope 413 is provided between the tops of the two convex frames 412, and an outer tension rope 414 is provided diagonally between the two flat frames 411. The resulting tensioned integral frame 41 has support capabilities. When the drone needs to be charged, the drone flies to the top of the light pole 1 and aligns with the tensioned integral frame 41 before descending. Upon landing, it contacts the top flat frame 411. Due to the tension structure, the flat frame 411 will sway with the drone's own weight and the impact of the rotor airflow, thus buffering the dynamic load during the drone's descent and protecting the slender light pole 1 structure. Compared to the heavy metal springs and the bulky vibration-absorbing sponges, the tensioned integral frame 41 provides buffering, ensuring a smaller size and lighter weight, making it suitable for the top of the slender light pole 1 and protecting the light pole 1.

[0023] Preferably, steel balls are provided at both ends of the central load-bearing rope 413. The two steel balls are rotatably connected to the holes opened on the convex frame 412. One end of the central load-bearing rope 413 is rotatably connected to a stud, and one of the steel balls is threadedly connected to the stud. Thus, during maintenance, the tension can be maintained by rotating the stud to shorten the distance between the two convex frames 412.

[0024] In another embodiment provided by the present invention, such as Figure 3As shown, a guide frame 43 is provided on the planar frame 411, and a four-sided pyramidal groove is provided on the guide frame 43. A guide frame 44 corresponding to the guide frame 43 is provided on the bottom of the drone. The guide frame 44 is fixed to the bottom of the drone by screws. The four-sided pyramidal groove-shaped guide frame 43 and the four-sided pyramidal guide frame 44 can play a role in alignment and guidance, reducing the error of the drone's descent. It can directly dock with the charging port for charging during descent. Although the four-sided pyramidal guide frame 44 has high guidance accuracy, the joint of the pyramid is easy to stick to the inner wall of the guide frame 43 and stop moving due to friction. When the tensioned frame 41 is under force, it will swing around the central load-bearing rope 413. When swinging, it will overcome the friction and promote the docking of the guide frame 44.

[0025] In another embodiment of the present invention, a bottom plate 42 is provided at the bottom of the lower shell 21. A groove 421 is provided on the bottom plate 42. A limiting plate 40 is slidably connected to the groove 421. There are four limiting plates 40. The limiting plates 40 are arranged in a circular array along the central load-bearing rope 413. When the UAV needs to take off, the four limiting plates 40 are driven to slide closer to the tensioning frame 41, so that the two planar frames 411 between the limiting plates 40 are restricted. This restricts and locks the degree of freedom of the tensioning frame 41 to swing along the central load-bearing rope 413, thereby providing a stable platform for the UAV during takeoff and reducing the impact on the UAV during takeoff.

[0026] Preferably, a sliding protrusion ring 420 is provided on the base plate 42, and a rotating ring 422 is rotatably connected to the sliding protrusion ring 420. The rotating ring 422 is provided with limiting protrusions 4221, and there are four sets of limiting protrusions 4221, which correspond to the four limiting plates 40 respectively. The outer tension rope 414 is an elastic rope, which gives the top planar frame 411 the freedom of swing. When the drone is landing, the rotating ring 422 rotates, so that the limiting plates 40 are in contact with the inner wall of the rotating ring 422. At this time, there is a gap between the limiting plates 40 and the planar frame 411. This gap is the degree of freedom of movement of the top planar frame 411, thereby limiting the range of horizontal freedom of the tensioned overall frame 41 and preventing the top planar frame from being... Excessive swing range of 411 causes the entire tension frame 41 to fall apart. A limiting groove 401 is provided on the limiting plate 40. When the limiting plate 40 is in contact with the inner wall of the rotating ring 422, the limiting groove 401 is still between the two planar frames 411, which is used to limit the vertical degree of freedom of the tension frame 41. When the UAV needs to take off, the rotating ring 422 is driven to rotate, causing the limiting protrusion 4221 to push the limiting plate 40, pushing the limiting plate 40 between the two planar frames 411 for vertical filling. After filling, the top planar frame 411 cannot swing, thus also limiting the horizontal degree of freedom based on swing, and realizing the locking of the tension frame 41.

[0027] Preferably, a push drive source 423 (which can be a telescopic motor) is provided on the base plate 42, and an extension plate 4201 corresponding to the push drive source 423 is provided on the rotating ring 422. The push drive source 423 pushes the extension plate 4201 to drive the rotating ring 422 to rotate. A spring plate 424 is provided on the base plate 42, and there are two extension plates 4201. One of the extension plates 4201 and the spring plate 424 has a spring, which is used to reset the rotating ring 422 after the push drive source 423 pushes it.

[0028] Preferably, the push drive source 423 can be hinged to the extension plate 4201 on the rotating ring 422 via an intermediate hinge, thereby driving the rotating ring 422 to rotate when it extends or retracts.

[0029] Preferably, a spring can be provided between the limiting plate 40 and the slide groove 421. The spring is used to pull the limiting plate 40 to re-adhere to the inner wall of the rotating ring 422 when the rotating ring 422 is rotated and reset.

[0030] In another embodiment of the present invention, a cable 51 is provided inside the lamp post 1. One end of the cable 51 is provided on the lower shell 21. A flip cover plate 221 is symmetrically rotatably connected to the upper shell 22. After receiving the falling drone, the two flip covers 221 are driven to flip and cover the upper shell 22 to avoid external dust and rain. The structure that drives the flip covers 221 to flip can be a motor provided on the upper shell 22.

[0031] Preferably, a tensioning wheel 52 for winding the cable 51 is rotatably connected to the light pole 1. The tensioning wheel 52 is driven by the traction motor 53 on the light pole 1, thereby driving the platform hangar 2 to move up and down along the light pole 1 for easy maintenance. A cover can be installed at the bottom of the light pole 1 to protect the traction motor 53.

[0032] In another embodiment of the present invention, a side limiting frame 20 for a clamping flip cover 221 is provided on the lamp post 1. An arc-shaped block 222 is provided on the flip cover 221. The upper shell 22 moves with the pull cable 51. When it is necessary to open the flip cover 221, the upper shell 22 is pulled upward along the lamp post 1 by the pull cable 51. At this time, the flip cover 221 moves to both sides due to the weight of the arc-shaped block 222 and opens. When it is necessary to close, the upper shell 22 is pulled downward along the lamp post 1 by the pull cable 51. At this time, due to the restriction of the side limiting frame 20, the arc-shaped block 222 moves downward with the upper shell 22 and closes. The opening and closing of the flip cover 221 is achieved by the movement of the upper shell 22.

[0033] Preferably, the side limiting frame 20 includes a recessed frame 203 corresponding to the flip cover plate 221 and a sealing head 202 disposed on the lamp post 1. The sealing head 202 is provided with a central tube 201 for the recessed frame 203 to slide. An elastic element 2031 is disposed between the recessed frame 203 and the central tube 201. The elastic element 2031 can be a spring. During maintenance, by driving the cable 51 to lower the platform hangar 2, the arc block 222 pushes the recessed frame 203 open and slides along the central tube 201, thereby disengaging from the side limiting frame 20 and enabling maintenance.

[0034] Electromagnets can be installed at the joint of the two flip-up covers 221. When the maintenance is completed and the device needs to be reset, the electromagnets are activated and the electromagnets on the two flip-up covers 221 attract each other. At this time, the platform hangar 2 moves upward through the platform hangar 2 and is pushed open by the arc block 222 to return to the top of the lamp post 1.

[0035] When preparing to receive the falling drone, the upper shell 22 is pulled upward along the light pole 1 by the cable 51. At this time, the flip cover 221 is opened by moving to both sides due to the weight of the arc block 222. Then the rotating ring 422 rotates, so that the limiting plate 40 fits against the inner wall of the rotating ring 422. At this time, there is a gap between the limiting plate 40 and the flat frame 411. This gap is the degree of freedom of movement of the top flat frame 411. Then the drone flies to the top of the light pole 1 and aligns with the tensioned integral frame 41 before starting to descend. When it lands, it contacts the top flat frame 411. Because of the tension structure, the flat frame 411 will sway with the impact of the drone's own weight and the rotor airflow, thus buffering the dynamic load when the drone lands and protecting the slender light pole 1 structure. At the same time, when the tensioned integral frame 41 is under force, it will swing around the central load-bearing rope 413. When swinging, it will overcome the friction and cause the guide frame 44 to connect. When the drone needs to take off, the rotating ring 422 is driven to rotate, causing the limiting protrusion 4221 to push the limiting plate 40, pushing the limiting plate 40 between the two planar frames 411 to fill in the vertical direction. After filling, the top planar frame 411 cannot swing, thus also limiting the horizontal degree of freedom based on swing, and realizing the locking of the tensioned overall frame 41.

[0036] The foregoing has only described certain exemplary embodiments of the present invention by way of illustration. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the foregoing drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
