Description

Technical Field

[0001] This utility model relates to the field of drone parking equipment technology, and in particular to a drone parking deck with noise reduction function. Background Technology

[0002] With the rapid development of drone technology, its application scenarios are becoming increasingly widespread, ranging from logistics and delivery to agricultural monitoring and emergency rescue. However, the noise and vibration generated by drones during takeoff and landing not only affect the comfort of the surrounding environment but may also damage the equipment itself.

[0003] Most drone landing pads on the market today prioritize structural stability and safety, with relatively little consideration for noise control. Existing landing pads are typically constructed from simple metal or concrete materials, which, while sturdy and durable, offer virtually no vibration damping or sound absorption. When a drone lands, the lack of an effective cushioning mechanism results in a significant impact force from the direct collision between the drone and the landing pad. This not only increases noise levels but can also damage the drone's delicate components. Furthermore, traditional landing pad designs fail to adequately absorb and isolate secondary noise generated by vibrations, significantly reducing overall noise reduction effectiveness.

[0004] Therefore, it is necessary to design a drone landing deck with noise reduction function to solve the above-mentioned technical problems. Utility Model Content

[0005] To overcome the shortcomings of existing helipads which typically lack vibration damping or sound absorption functions, resulting in significant impact forces from direct collisions between the drone and the helipad when the drone lands due to the lack of an effective buffer mechanism, which not only increases noise levels but may also damage the drone, this invention provides a drone helipad deck with noise reduction function.

[0006] The technical implementation scheme of this utility model is as follows: a drone landing deck with noise reduction function, including a support base, a noise reduction frame and a landing plate. The noise reduction frame is fixedly connected to the top of the support base, and the landing plate is slidably connected to the top of the noise reduction frame. It also includes dampers and buffer springs. Multiple dampers are provided between the landing plate and the noise reduction frame. Each damper is externally fitted with a buffer spring, and both ends are fixedly connected between the landing plate and the noise reduction frame.

[0007] In a preferred embodiment of the present invention, the device further includes a mounting plate, a noise reduction curtain, and a sliding plate. Mounting plates are symmetrically and fixedly connected to the left and right sides of the top of the support base. The mounting plates are located between the top of the support base and its front and rear sides. A noise reduction curtain is provided on the opposite side of the two mounting plates. A sliding plate is fixedly connected to the inner side of each noise reduction curtain. Slide grooves are provided on the front and rear edges of the mounting plates. The two sides of the lower part of the sliding plate are embedded in the slide grooves and can slide along the direction of the slide grooves.

[0008] In a preferred embodiment of this utility model, both the noise-reducing frame and the noise-reducing curtain are made of noise-reducing material.

[0009] In a preferred embodiment of this utility model, it further includes an electric slide rail, an electric slider, a detector, and a controller. Electric slide rails are installed on the front and rear sides of the support base, and electric sliders that can slide left and right on the side of the two electric slide rails that are far apart from each other are symmetrically provided. The side of the electric sliders that are far apart from each other on both sides are fixedly connected to the corresponding sliding plate. A detector is installed on the top of the stop plate, and a controller is installed on the front side of the stop plate. The controller is electrically connected to the detector and the electric slide rail.

[0010] In a preferred embodiment of the present invention, a buffer pad is also included, with a buffer pad laid on the top of the stop plate and the detector disposed in the central area of ​​the buffer pad.

[0011] In a preferred embodiment of the present invention, an observation plate is also included, with observation plates provided on both sides of the mounting plate.

[0012] Compared with the prior art, the present invention has the following advantages:

[0013] 1. This utility model effectively absorbs the impact force generated when the drone lands by setting up a combination structure of damper and buffer spring, combined with a sliding stop plate design, achieving good shock absorption and noise reduction effects.

[0014] 2. This utility model uses an automatic control system composed of an electric slide rail, an electric slider, a detector, and a controller to automatically adjust the position of the landing plate and the shielding structure according to the landing status of the UAV, thereby improving intelligent management and ease of operation.

[0015] 3. This utility model achieves multiple noise reduction protection and visual monitoring functions by setting noise reduction curtains around the stop plate, setting observation windows on the mounting plate, and cooperating with buffer pads, thus achieving a balance between safety and practicality.

[0021] Example: A drone landing pad deck with noise reduction function, such as Figures 1-4 As shown, it includes a support base 1, a noise reduction frame 2, a landing plate 3, a damper 4, and a buffer spring 5. The top of the support base 1 is connected to the noise reduction frame 2 by bolts. The noise reduction frame 2 is made of noise reduction material. The landing plate 3 is slidably connected to the top of the noise reduction frame 2. Multiple dampers 4 are provided between the landing plate 3 and the noise reduction frame 2. Each damper 4 is fitted with a buffer spring 5. Both ends are connected to the landing plate 3 and the noise reduction frame 2 by bolts, which are used to absorb the impact energy generated when the drone lands.

[0022] like Figures 1-3 As shown, it also includes a mounting plate 6, a noise-reducing curtain 7, and a sliding plate 8. The mounting plates 6 are symmetrically connected to the top left and right sides of the support base 1 by bolts. The mounting plates 6 are located between the top of the support base 1 and its front and rear sides to form a stable support structure. Noise-reducing curtains 7 are respectively provided on the opposite side of the mounting plates 6. The noise-reducing curtains 7 are all made of noise-reducing material. The inner side of each noise-reducing curtain 7 is connected to the sliding plate 8 by bolts. The mounting plates 6 have grooves on the front and rear edges. The two sides of the lower part of the sliding plate 8 are embedded in the grooves and can slide along the direction of the grooves, thereby driving the noise-reducing curtain 7 to open and close.

[0023] The landing plate 3 is connected to the noise reduction frame 2 below through the damper 4 and the buffer spring 5, forming the main shock absorption structure. When the drone lands on the surface of the landing plate 3, the landing plate 3 will move slightly downward due to the impact. At this time, the damper 4 converts the kinetic energy into heat energy, and the buffer spring 5 on the outside further absorbs the remaining vibration energy, effectively reducing the vibration and noise caused by the impact.

[0024] like Figures 1-4As shown, it also includes an electric slide rail 9, an electric slider 10, a detector 11, a controller 12, a buffer pad 13, and an observation plate 14. Electric slide rails 9 are installed on the front and rear sides of the support base 1. On the side of the two electric slide rails 9 that are far apart from each other, there are electric sliders 10 that can slide left and right on their tracks. The side of the electric sliders 10 that are far apart from each other on both sides are fixedly connected to the corresponding sliding plate 8. A detector 11 is installed on the top of the landing plate 3. A controller 12 is installed on the front side of the landing plate 3. The controller 12 is electrically connected to the detector 11 and the electric slide rail 9 to realize automatic control of the position of the landing plate 3 and the shielding structure. A buffer pad 13 is laid on the top of the landing plate 3. The detector 11 is set in the central area of ​​the buffer pad 13. The buffer pad 13 is used to protect the bottom of the drone and assist in shock absorption. Observation plates 14 are set in the middle of the mounting plates 6 on both sides. The observation window is made of transparent and weather-resistant material, which makes it convenient for staff to observe the landing status of the drone in real time.

[0025] Before the drone prepares to land, the operator first turns on the equipment power and initializes the settings via controller 12. At this time, detector 11 is in standby mode, used to monitor the drone's position information in real time. When detector 11 detects that the drone is approaching and about to land, controller 12 automatically activates the electric slide rail 9 system based on the received signal.

[0026] Electric slide rails 9 are installed on the front and rear sides of the support base 1. Each electric slide rail 9 is equipped with an electric slider 10 that can slide left and right on the track. Under the action of the controller 12, the electric slider 10 drives the sliding plate 8 to move along the sliding groove on the mounting plate 6, thereby controlling the opening or closing of the noise reduction curtain 7. When the drone is about to land, the noise reduction curtain 7 automatically opens to both sides. Firstly, it provides landing space for the drone. Secondly, the semi-enclosed structure can block some of the air pressure waves caused by the high-speed rotation of the rotor, absorbing some of the drone's noise. After the drone completes landing, the noise reduction curtain 7 automatically closes, forming a relatively closed acoustic environment to reduce the outward transmission of noise.

[0027] In addition, a buffer pad 13 is laid on top of the landing plate 3. The buffer pad 13 not only protects the bottom structure of the drone but also enhances the overall shock absorption effect and improves stability during takeoff and landing. With both the noise reduction frame 2 and the noise reduction curtain 7 made of noise-reducing materials, the entire device works together from both structural and material perspectives to further improve noise reduction performance. For easy manual monitoring, an observation plate 14 made of transparent, weather-resistant material is located in the middle of the mounting plate 6. Staff can observe the drone's landing status in real time through this window, ensuring the entire process is safe and controllable.

[0028] In summary, this device uses detector 11 to sense the drone's position, controller 12 to automatically adjust the position of the shielding structure and landing plate 3, combined with a composite shock absorption system consisting of damper 4 and buffer spring 5, and a multi-layer noise reduction structure design, to achieve efficient control of impact force and noise during drone landing, thereby improving the safety, stability and user comfort of the equipment.

Therefore, the scope of this invention should be limited only by the appended claims.
