Description

Technical Field

[0001] This invention relates to the field of landing pad technology, specifically a prefabricated EVTOL landing pad. Background Technology

[0002] EVTOL, or Electric Vertical Take-Off and Landing Aircraft, is an aircraft that uses electric power and is capable of vertical take-off and landing. This type of aircraft combines the vertical take-off and landing capabilities of helicopters with the fast cruise characteristics of airplanes, while also having advantages such as low noise and zero emissions, making it very suitable for urban air traffic. With the development of EVTOL technology, take-off and landing pads have been designed as their take-off and landing points in order to adapt to the characteristics and needs of this new type of aircraft.

[0003] Currently, EVTOL landing pads are relatively large, making assembly quite complicated. Furthermore, EVTOL landing pads need to be manufactured on demand according to different application scenarios, resulting in a narrow range of applications. Summary of the Invention

[0004] To address the shortcomings of existing technologies, this invention provides a prefabricated EVTOL landing pad, which mainly solves the problems of the large size of current EVTOL landing pads, the cumbersome assembly process, and the narrow applicability of EVTOL landing pads due to their need for on-demand manufacturing based on different application scenarios.

[0005] To achieve the above objectives, the present invention provides the following technical solution: An EVTOL landing pad includes a base frame, which is formed by interlacing and welding multiple support plates. Multiple sides of the base frame extend upward to form embedded cavities. Floor components are detachably connected to the embedded cavities. Connecting seats are fixed at the four corners of the bottom of the base frame by buffer components. Multiple through holes are opened inside the connecting seats. Half screws are inserted into the through holes and fixed to the object to be installed.

[0006] Furthermore, the object to be installed is a floating vessel.

[0007] Based on the aforementioned solution, the object to be installed is the rooftop.

[0008] As a further embodiment of the present invention, the object to be installed is the ground.

[0009] Furthermore, the buffer assembly comprises two bottom fixing ears, four side fixing ears, and four support rods. The two bottom fixing ears are welded to the middle of the bottom of the base frame, and the four side fixing ears are welded to the four corners of the base frame. A fixing seat is welded to the top of the multiple connecting seats. A damper is hinged to one side of the fixing seat, and one end of the damper is rotatably connected to the side fixing ear. The two ends of the four support rods are respectively welded with connecting end two and connecting end one. The two connecting end two on the same side are hinged to the bottom of the bottom fixing ears. The connecting end one is detachably fixed to the fixing seat by screws.

[0010] Based on the aforementioned scheme, multiple reinforcing ribs are welded to the connection points of the multiple connecting ends 2 and 1 with the support rod.

[0011] As a further embodiment of the present invention, the floor assembly includes multiple mounting plates one and multiple mounting plates two, which are staggered. Each of the mounting plates one and two has a protrusion and a groove on an adjacent side, and the protrusion and the groove fit together.

[0012] Furthermore, both ends of the plurality of mounting plates one and two are provided with through mounting holes.

[0013] Based on the aforementioned scheme, a guardrail is fixed to one side of the base frame with bolts, and a step is provided between the guardrail and the base frame.

[0014] Compared with the prior art, the present invention provides a prefabricated EVTOL landing pad, which has the following advantages: 1. This invention uses splicing to form floor components, which are then assembled with the embedded cavity at the top of the base frame to form a landing pad. The construction time is short. Then, the connecting seat is installed and fixed to the floating ship, roof or ground, so that it can be used in different application scenarios, thus having a wider range of applications. In addition, because there is a buffer component between the base frame and the connecting seat, the landing pad is buffered when subjected to force, which further improves the use effect of the landing pad.

[0015] 2. The present invention involves embedding the protrusion on the first mounting plate into the groove on the second mounting plate, and then alternately installing and snapping the first and second mounting plates to cover the embedded cavity on the base frame. Finally, screws are passed through the mounting holes to connect and fix the plate to the base frame, making it simple and convenient to use.

[0016] 3. The present invention uses a damper to connect and fix the base frame to the fixed seat, and the damper itself has a buffering capacity to effectively buffer the base frame when strong pressure occurs.

[0017] 4. The outer surface of the landing pad in this invention is coated with a protective paint, which gives it resistance to acids and alkalis, resistance to salt spray, strong resistance to freeze-thaw cycles, low maintenance costs, and an aesthetically pleasing appearance.

Both ends of the mounting plates 14 and 15 have through mounting holes 18. The protrusion 19 on the mounting plate 14 is inserted into the groove 20 of the mounting plate 25, and the mounting plates 14 and 25 are alternately installed and snapped together, covering the embedding cavity 16 on the base frame 3. Finally, screws are passed through the mounting holes 18 and connected to the base frame 3 for fixation. This method is simple and convenient to use. The mounting plates 14 and 15 can be pre-drilled for holes and wiring channels for lighting fixtures, such as navigation lights.

[0024] The working principle of this embodiment is as follows: In use, the protrusion 19 on the mounting plate 14 is embedded into the groove 20 of the mounting plate 25. Then, the mounting plates 14 and 25 are alternately installed and snapped together to cover the embedded cavity 16 on the base frame 3. Then, the mounting plate 3 is connected and fixed with the mounting plate 3 through the mounting hole 18 by screws to form a landing pad. The construction time is short. Then, the connecting seat 6 is installed and fixed to the floating ship, roof or ground, so that it can be used in different application scenarios, making it more applicable. The base frame 3 is connected and fixed to the fixed seat 13 by the damper 10, and the damper 10 itself has the buffering capacity to effectively buffer the base frame 3 when strong pressure occurs, further improving the use effect of the landing pad.
