Description

Technical Field

[0001] This utility model belongs to the field of signal enhancement devices, specifically a signal enhancement device and system for UAV relay radios. Background Technology

[0002] With the rapid development of drone technology and its widespread application in emergency communication and disaster relief, higher demands are being placed on the ability of drones to carry communication equipment. Traditional ground relay base stations have limitations in terms of mobility and coverage flexibility, making it difficult to meet the real-time communication needs in dynamic scenarios. Against this backdrop, an innovative communication solution is proposed: a signal enhancement device for a relay radio mounted on a drone. By combining the drone's flight capabilities with the relay radio's signal forwarding function, the signal coverage range can be flexibly adjusted, effectively improving the signal transmission quality and stability in complex environments and meeting the real-time communication needs in dynamic scenarios.

[0003] Various drone relay radio signal enhancement devices already exist in the prior art. For example, patent publication number CN219018816U discloses a remote sensing signal relay enhancement device for drones, including a repeater body (i.e., a relay radio), a top plate, side plates, a bottom plate, a mounting box, a wiring protection sleeve, and a signal pole. The top plate, side plates, and bottom plate work together to provide initial protection for the repeater body, preventing damage to the device from accidental collisions. By setting up the signal pole and the repeater body, drones can achieve stable remote sensing signal transmission through the relay signal device in complex urban environments or under long-distance remote control conditions.

[0004] However, the device described in the aforementioned patent has significant drawbacks in use. Specifically, while the drone receives signals via a signal pole during operation, the signal pole remains exposed to the external environment when not in operation, such as when parked. Given the complex operating environments of drones, often including the field, construction sites, and dusty or humid conditions, the exposed signal pole is susceptible to structural damage from impacts, scratches, dust accumulation, and rain erosion. This damage reduces signal transmission and reception efficiency, increases signal attenuation, and severely impacts the quality and stability of the drone's signal transmission. Utility Model Content

[0005] To address the aforementioned shortcomings in the existing technology, this utility model aims to provide a signal enhancement device and system for UAV relay radios, so as to effectively protect the signal pole in the non-working state while ensuring signal transmission performance in the working state.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0007] This utility model provides a signal enhancement device for a drone relay radio, comprising,

[0008] The box body has a hinged door panel at the top;

[0009] The drive mechanism is used to drive the door panel to open and close, and its output end is connected to the door panel;

[0010] The repeater radio is slidably installed inside the enclosure.

[0011] The signal pole is slidably installed inside the housing and electrically connected to the repeater station.

[0012] The lifting assembly is located inside the enclosure. Its output end is connected to the repeater radio and the signal pole. The lifting assembly controls the repeater radio and the signal pole to extend or retract from the enclosure.

[0013] As a limitation of this utility model: the lifting assembly includes a driving component, a scissor mechanism and a support plate, the driving component is connected to the input end of the scissor mechanism, and the support plate is disposed at the output end of the scissor mechanism; the relay radio is fixed on the support plate, and the signal pole is erected on the top of the relay radio.

[0014] As a further limitation of this utility model: the driving component includes a motor, a lead screw, and a moving block. The lead screw is rotatably disposed inside the housing. The output end of the motor is connected to the lead screw. The moving block is threaded onto the lead screw and is fixedly connected to the input end of the scissor mechanism. The moving block moves along the axial direction of the lead screw to control the extension and retraction of the scissor mechanism to realize the lifting and lowering of the bearing plate.

[0015] As another limitation of this utility model: the relay radio is provided with a windproof plate for blocking the wind from the signal pole. The windproof plate is located on the left end of the windward side of the signal pole, and the size of the windproof plate is adapted to the size of the signal pole.

[0016] As a further limitation of this utility model: a tray is rotatably mounted on the relay radio, the tray rotates around the circumference of the relay radio, the axis of rotation of the tray is perpendicular to the upper surface of the relay radio, and the signal pole and windproof plate are fixed on the tray.

[0017] The pallet is also fixed with a directional plate that is driven by the wind to rotate the pallet. The directional plate and the windproof plate are set opposite to each other about the central axis of the pallet, and the windward side of the directional plate is perpendicular to the windproof side of the windproof plate.

[0018] As a further limitation of this utility model: the windproof plate is an arc-shaped plate with a concave orientation towards the signal pole.

[0019] As another limitation of this utility model: a pivot is fixedly provided on the top of the box, and the door panel is fixedly sleeved on the pivot;

[0020] The drive mechanism includes a pull rope that is movably embedded in the inner wall of the housing. The pull rope is sleeved on the outer contour of the rotating shaft, and the pull rope is driven by friction with the rotating shaft. Both ends of the pull rope extend out of the inner wall of the housing, and the first end of the pull rope is fixedly connected to the top surface of the lifting assembly, and the second end of the pull rope is fixedly connected to the bottom surface of the lifting assembly.

[0021] As a further limitation of this utility model: the door panel includes a first door panel and a second door panel with the same structure and symmetrically arranged. The first door panel and the second door panel are each hinged to the top of the box through a pivot. The opening ends of the first door panel and the second door panel abut against each other when the box is closed.

[0022] As a further limitation of this utility model: the box body and door panel are both made of aluminum alloy.

[0023] This utility model also provides a UAV relay radio signal enhancement system, including a remote control component and a UAV relay radio signal enhancement device, wherein the remote control component is communicatively connected to the drive component.

[0024] By adopting the above technical solution, the beneficial effects achieved by this utility model compared with the prior art are as follows:

[0025] This utility model includes a housing, a door panel, a drive mechanism, a repeater radio, a signal pole, and a lifting assembly. The door panel is hinged to the top of the housing, and the drive mechanism is used to drive the door panel to open and close. The repeater radio and the signal pole are both slidably disposed inside the housing, and the lifting assembly is used to control the repeater radio and the signal pole to extend out of or retract into the housing.

[0026] During implementation, when the UAV is in operation, the lifting component controls the relay radio and signal pole to rise. At the same time, the drive mechanism controls the door panel to open, so that the relay radio and signal pole rise to extend out of the housing. The signal pole receives the signal and transmits the remote sensing signal through the relay radio.

[0027] When the drone is not in operation, the lifting assembly controls the relay radio and signal pole to descend and retract into the housing, while the right drive mechanism controls the door panel to close. This protects the signal pole and relay radio from exposure and potential damage.

[0028] In summary, this invention can effectively protect the signal pole when it is not in operation, and also ensure the signal reception efficiency when it is in operation, thus guaranteeing the quality and stability of signal transmission. This invention is applicable to the UAV remote sensing signal transmission industry and is used in conjunction with the UAV fuselage. Attached Figure Description

[0038] Example 1: A signal enhancement device for UAV relay radio

[0039] like Figures 1-5 As shown, this embodiment includes a housing 1, a door panel 2, a drive mechanism, a repeater radio 4, a signal pole 5, and a lifting assembly. The door panel 2 is hinged to the top of the housing 1, and the drive mechanism is used to drive the door panel 2 to open and close. The repeater radio 4 and the signal pole 5 are both slidably disposed inside the housing 1, and the lifting assembly is used to control the repeater radio 4 and the signal pole 5 to extend out of or retract into the housing 1.

[0040] I. Lifting components;

[0041] like Figure 2 , 4 As shown, the lifting assembly is located inside the housing 1 and includes a drive unit 6, a scissor mechanism 7, and a support plate 8. The drive unit 6 is connected to the input end of the scissor mechanism 7, which refers to the rear end of the first connecting rod 9 in the scissor mechanism 7. The support plate 8 is located at the output end of the scissor mechanism 7, which refers to the top of the scissor mechanism 7. The support plate 8 is fixedly connected to the front end of the second connecting rod 10, and the rear end of the third connecting rod 11 is slidably disposed on the bottom surface of the support plate 8, allowing it to slide in the forward and backward directions. In this embodiment, the scissor mechanism 7 adopts existing technology. The structure formed by the scissor mechanism 7 and the support plate 8 is similar to that of the existing scissor lift platform, and its structure and working principle are the same as those of the existing scissor lift platform, which will not be described in detail here.

[0042] The drive unit 6 includes a motor 61, a lead screw 62, and a moving block 63. The lead screw 62 is rotatably mounted inside the housing 1 via a lead screw seat 64, and its axial direction extends in the front and rear directions. The front end of the lead screw 62 is connected to the output end of the motor 61 via a coupling. The moving block 63 is threaded onto the lead screw 62, and the moving block 63 is fixedly connected to the input end of the scissor mechanism 7. Figure 4 As shown, the movable block 63 is connected to the rear end of the first connecting rod 9 via a rotating rod 12. One end of the rotating rod 12 is fixedly connected to the movable block 63, and the other end passes through the ear plate 13 and is rotatably connected to the rear end of the first connecting rod 9. Regarding the ear plates 13, in this embodiment, two ear plates 13 are provided at the bottom and top of the scissor mechanism 7. The two ear plates 13 at the bottom are connected to the bottom wall of the housing 1, and the two ear plates 13 at the top are connected to the support plate 8.

[0043] Working principle: Motor 61 drives lead screw 62 to rotate. Under the threaded engagement, moving block 63 moves along the axial direction of lead screw 62 to control the extension and retraction of the rear end of the first connecting rod 9 in scissor mechanism 7, thereby raising and lowering the bearing plate 8. Moving block 63 is threaded onto lead screw 62. The rotation of lead screw 62 causes moving block 63 to move linearly along the axial direction of lead screw 62. This method is existing technology.

[0044] It should be noted that the lifting assembly in this embodiment can also be replaced with any other structure in the prior art, such as a hydraulic cylinder, in which the piston rod end of the hydraulic cylinder is fixedly connected to the relay radio 4 to drive the lifting of the relay radio 4.

[0045] II. Repeater radio 4 and signal pole 5;

[0046] The output end of the lifting assembly is connected to the repeater radio 4 and the signal pole 5. Here, the output end of the lifting assembly refers to one end of the support plate 8. The lifting assembly controls the repeater radio 4 and the signal pole 5 to extend out of or retract into the housing 1.

[0047] Specifically, such as Figure 2 , 3 As shown, the repeater 4 is fixed on the support plate 8, and the signal pole 5 is installed vertically on the top of the repeater 4. The repeater 4 and the signal pole 5 can slide along the vertical direction of the housing 1 to rise or fall under the drive of the lifting assembly.

[0048] The signal pole 5 is electrically connected to the repeater radio 4; the specific structure of the repeater radio 4 and the signal pole 5, as well as the way they are electrically connected, are existing technologies and will not be described in detail in this embodiment.

[0049] 3. Windproof panel 14;

[0050] Considering that the signal pole 5 extending from the housing 1 will be affected by wind during drone flight, to prevent the signal pole 5 from bending, such as Figure 2 , 3 As shown, the relay radio 4 is equipped with a windproof plate 14 to shield the signal pole 5 from the wind. The windproof plate 14 is located at the front end of the signal pole 5 on the windward side. In this embodiment, it is assumed that the drone flies from back to front, so the windproof plate 14 is located at the front end of the signal pole 5. The size of the windproof plate 14 is adapted to the size of the signal pole 5. Adaptation here means: 1. The height of the windproof plate 14 is greater than or equal to 2 / 3 of the height of the signal pole 5, which can ensure that the signal pole 5 is not blown down by the wind, while not affecting the signal reception; 2. The width of the windproof plate 14 is greater than the farthest distance between multiple signal poles 5 in the left and right directions, so as to shield all signal poles 5 from the wind. Here, the width refers to the dimension in the left and right directions.

[0051] In this embodiment, the windproof plate 14 is an arc-shaped plate recessed towards the signal pole 5. On the vertical plane in the left and right directions, the left and right ends of the arc-shaped plate can block all the signal poles 5, thus achieving the effect of wind protection. In addition, the use of an arc-shaped plate in this embodiment, compared with a flat plate structure, can effectively reduce wind resistance by optimizing the airflow path.

[0052] IV. Pallet 15 and Directional Plate 16;

[0053] like Figure 2 , 3 As shown, tray 15 is rotatably mounted on repeater radio 4, and signal pole 5 and windproof plate 14 are both fixed on tray 15. Specifically, in this embodiment, tray 15 and repeater radio 4 are connected by a slewing bearing, allowing tray 15 to rotate circumferentially around repeater radio 4; that is, the axis of rotation of tray 15 is perpendicular to the upper surface of repeater radio 4. It should be further noted that... Figure 2 , 3 The slewing bearing between the middle tray 15 and the repeater 4 is not shown; only the tray 15 and the repeater 4 are shown for illustration.

[0054] The tray 15 is designed to rotate circumferentially around the relay radio 4 to ensure that the wind deflector 14 follows the drone's direction of flight. To this end, a directional plate 16, driven by wind, is fixed to the tray 15. The directional plate 16 and the wind deflector 14 are positioned opposite each other about the central axis of the tray 15. In this embodiment, the wind deflector 14 is located in front of the central axis of the tray 15, and the directional plate 16 is located behind it. The directional plate 16 is fixedly connected to the tray 15 via a support rod 17. The windward surface 18 of the directional plate 16 is perpendicular to the windproof surface 19 of the wind deflector 14. When the drone turns left or right, the wind force acts on the windward surface 18 of the directional plate 16, generating a circumferential torque that drives the tray 15 to rotate so that the wind deflector 14 faces the oncoming wind. This structure ensures that the wind deflector 14 can block the wind from the signal pole 5 regardless of the drone's flight direction.

[0055] 5. Door panel 2, drive mechanism;

[0056] like Figure 1 , 2 As shown, the door panel 2 is hinged to the top of the box body 1 in the following way: the top of the box body 1 is fixed with a rotating shaft 20 extending axially in the left and right directions, and the door panel 2 is fixedly sleeved on the rotating shaft 20. When the rotating shaft 20 rotates, it can drive the door panel 2 to rotate to realize opening and closing.

[0057] The output end of the drive mechanism is connected to the door panel 2 and is used to drive the door panel 2 to open and close.

[0058] The drive mechanism includes a pull rope 3 that is movably embedded in the inner wall of the housing 1, such as... Figure 2 , 5 As shown, a limiting groove 21 is formed in the inner wall of the housing 1. A portion of the pull rope 3 is embedded in the limiting groove 21, allowing the pull rope 3 to move within it. The pull rope 3 is sleeved on the outer contour of the rotating shaft 20, with its middle section also sleeved on the outer contour. Both ends of the pull rope 3 extend out of the inner wall of the housing 1. The first end 22 of the pull rope 3 is fixedly connected to the top surface of the lifting assembly, and the second end 23 is fixedly connected to the bottom surface of the lifting assembly. Specifically, the first end 22 of the pull rope 3 is fixedly connected to the upper surface of the support plate 8 via an ear plate, and the second end 23 is fixedly connected to the lower surface of the support plate 8 via an ear plate. The pull rope 3 is driven by friction with the rotating shaft 20. In this embodiment, the outer contour of the rotating shaft 20 is provided with a threaded structure to increase friction with the pull rope 3. Figure 1 , 2 The thread on the rotating shaft 20 in section 5 is not shown.

[0059] When the lifting assembly drives the support plate 8 to rise, the support plate 8 causes the second end 23 of the pull rope 3 to rise. The second end 23, under tension, pulls the pull rope 3, which in turn drives the rotating shaft 20 along... Figure 2 Rotate in the direction of the middle arrow to open door panel 2. In this embodiment, the rise of the support plate 8 and the opening of door panel 2 are synchronized, that is, when the repeater radio 4 and the signal rod 5 rise together, door panel 2 opens, allowing the repeater radio 4 and the signal rod 5 to extend from the top of the housing 1.

[0060] Conversely, when the lifting assembly drives the support plate 8 to descend, the support plate 8 causes the first end 22 of the pull rope 3 to descend. The tension on the first end 22 pulls the pull rope 3, which in turn causes the rotating shaft 20 to move along the same path as the load. Figure 2 Rotate in the opposite direction of the middle arrow to close door 2. In this embodiment, the descent of the support plate 8 and the closing of door 2 are synchronized. That is, when the repeater radio 4 and the signal pole 5 descend together, door 2 gradually closes, allowing the repeater radio 4 and the signal pole 5 to retract into the housing 1 and be sealed inside the housing 1.

[0061] The drive mechanism designed in this embodiment is to realize the synchronous movement of the lifting component and the door panel 2 when opening and closing. Of course, the drive mechanism can also be replaced with any kind of automatic control structure in the prior art, as long as it can realize the automatic opening and closing of the door panel 2.

[0062] Furthermore, such as Figure 1 , 2 As shown, door panel 2 includes a first door panel 201 and a second door panel 202 with identical structures and symmetrical arrangement. The first door panel 201 and the second door panel 202 are each hinged to the top of the housing 1 via a pivot 20. Figure 1 As shown, the front end of the first door panel 201 is hinged and fixed by a pivot 20, and the rear end of the second door panel 202 is hinged and fixed by a pivot 20. The opening end of the first door panel 201 (i.e., the rear end of the first door panel 201) and the opening end of the second door panel 202 (i.e., the front end of the second door panel 202) abut against each other when the housing 1 is closed, forming a closed state.

[0063] In this embodiment, the door panel 2 is configured as a separate first door panel 201 and a second door panel 202, each controlled independently by its own drive mechanism, which can effectively reduce the workload of a single drive mechanism. Compared to the entire door panel 2 being driven by a single drive mechanism, the drive mechanism needs to bear a greater workload, is prone to damage after prolonged use, and will also cause the opening and closing response speed of the door panel 2 to slow down.

[0064] In this embodiment, both the box body 1 and the door panel 2 are made of aluminum alloy, which is lightweight, high-strength, and corrosion-resistant.

[0065] Working principle of this embodiment:

[0066] During flight, motor 61 drives lead screw 62 to rotate, causing moving block 63 to move forward. At this time, scissor mechanism 7 drives support plate 8 to rise, and relay radio 4 and signal pole 5 to rise as well. Simultaneously, the rising support plate 8 pulls the second end 23 of pull rope 3, thereby controlling door plate 2 to open. Relay radio 4 and signal pole 5 rise to extend from the housing 1. Signal pole 5 receives signals and transmits remote sensing signals through relay radio 4.

[0067] When the drone is parked, motor 61 rotates in the reverse direction, causing moving block 63 to move backward. At this time, scissor mechanism 7 drives support plate 8 to descend, and relay radio 4 and signal pole 5 descend and gradually retract into the housing 1. Simultaneously, the descending support plate 8 pulls the first end 22 of pull rope 3, thereby controlling door plate 2 to rotate in the reverse direction and close. At this time, housing 1 is in a closed state, which can protect signal pole 5 and relay radio 4 from being exposed and damaged. This embodiment can effectively protect signal pole 5 in the non-operating state, while also ensuring signal transmission performance in the operating state, thus guaranteeing the quality and stability of drone signal transmission.

[0068] Example 2: A UAV relay radio signal enhancement system

[0069] This embodiment includes a remote control component and Embodiment 1. The remote control component is communicatively connected to the drive component 6, that is, the signal output terminal of the remote control component is wirelessly connected to the signal input terminal of the motor 61. Wireless remote control enables the motor 61 to start and rotate in both directions, thereby controlling the relay radio 4 and the signal pole 5 to extend from or retract into the housing 1. The structure of the remote control component is prior art, and the control principle between the remote control component and the motor 61 is also prior art; therefore, it will not be described in detail in this embodiment.

[0070] The usage process of this embodiment is described in Embodiment 1.

[0071] It should be noted that the above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the above embodiments, those skilled in the art can still modify the technical solutions described in the above embodiments or make equivalent substitutions for some of the technical features.
