Abstract
Description
Technical Field
[0001] This utility model relates to the field of unmanned aerial vehicle (UAV) technology, and more specifically, to a low-cost folding helipad. Background Technology
[0002] With the development of technology, drones are transforming from "flying cameras" into intelligent aerial robots. Whether used for agricultural operations, transporting or hoisting goods, in agriculture, forestry, fisheries, animal husbandry, disaster relief, logistics, or for scientific research, such as typhoon monitoring or data collection at volcanoes, drones can perform various activities. As the application of drones in different scenarios increases, the requirements for drone helipad setups are also becoming more stringent.
[0003] Existing drone landing pads often employ a foldable flat panel structure. For example, the foldable landing pad disclosed in patent application CN108755462A includes folding blocks, hinges, a grounding / disengagement area, and a grounding positioning area. The folding blocks are the foldable parts around the landing pad. Furthermore, patent CN221367564U discloses a landing pad including a foldable landing board with a balancing bracket below it for adjusting its level. The balancing bracket is detachably connected to the landing board and includes at least three support rods, each consisting of at least two rod sections that slide together along its length. While this design allows the landing board to remain level in uneven areas, the multiple support rods weaken the anti-slip performance, making it prone to slipping on wet surfaces. Therefore, researching ways to expand the application range of landing pads, reduce their cost, and improve their folding ease is of significant importance.
[0004] Patent CN215859342U discloses a drone hangar with automatic centering and automatic charging functions. It includes a base plate, an outer frame mounted on the upper end of the base plate, an access door movably mounted on the front end of the outer frame, a display screen mounted on the left end of the outer frame, and a lifting device installed in the inner cavity of the outer frame. The lifting device is installed in the upper middle part of the base plate. The lifting device includes a folding frame, an electric push rod, a connecting shaft, and a lifting landing pad. The lifting landing pad is located above the folding frame, and the connecting shaft is located between two adjacent folding frames for connecting them. The connecting shaft is connected to the electric push rod. Under the action of the electric push rod, the connecting shaft drives the folding frame to extend or retract, thus raising or lowering the landing pad. This design facilitates drone takeoff and storage, but due to its complex structure, it is prone to high costs. Utility Model Content

Therefore, they should not be construed as limitations on this utility model.
[0022] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.
[0023] This embodiment is for a helipad. Similar to a conventional helipad, the overall structure consists of a helipad platform and a support frame.
[0024] To address the issues of high cost and complex folding mechanisms in existing helipad technologies, this embodiment proposes a low-cost folding helipad, comprising a helipad platform 1 and a folding support 2. The bottom of the helipad platform 1 is positioned on top of the folding support 2, and the top of the helipad platform 1 is connected to or detached from the bottom of a drone or model aircraft. The bottom of the folding support 2 is either flush with or detached from the ground. The folding support 2 includes a first folding frame 21, a second folding frame 22, and a pivot 23. The top and bottom of the second folding frame 22 are respectively flush with the bottom and top of the inner side of the first folding frame 21. Both the first folding frame 21 and the second folding frame 22 are rotatably positioned on the outside of the pivot 23 to enable the opening and folding of the folding support 2.
[0025] By setting up the helipad, the structure of the helipad can be effectively simplified, the cost of the helipad can be reduced, the overall structural mechanical stability of the helipad can be improved, the applicable scope of the helipad can be expanded, the folding method of the helipad can be simplified, and the helipad can be quickly and efficiently folded and assembled; it also helps to reduce the space occupied by the helipad.
[0026] The folding bracket 2 also includes a reinforcing plate 3, the bottom or top of which is connected to the top or bottom of the folding frame 21 and the pivot 23, respectively. At least one reinforcing plate 3 is provided. Preferably, two reinforcing plates 3 are provided; the bottom of one reinforcing plate 3 is screwed to the top of the folding frame 21 and the top of the pivot 23, respectively. The top of the other reinforcing plate 3 is screwed to the bottom of the folding frame 21 and the pivot 23, respectively. The reinforcing plate 3 is cylindrical. Preferably, the reinforcing plate 3 has a cylindrical structure.
[0027] By setting up the reinforcing plate 3, the stability of the connection between the first folding frame 21 and the pivot 23 can be effectively improved. It can also play a limiting role, ensuring the reliability of the connection between the pivot 23 and the first folding frame 21 and the second folding frame 22 during the opening and closing of the folding bracket 2.
[0028] The landing platform 1 is flat and square. The dimensions of the landing platform 1 can be any of 1.5m, 2m, or 2.5m. The landing platform 1 includes an inner marking frame 11 and an outer marking frame 12. Both the inner and outer marking frames 11 and 12 are located on the top of the landing platform 1. The inner marking frame 11 is located inside the outer marking frame 12. The landing platform 1 also includes a symbol 13, which is located at the center of the inner marking frame 11; this symbol is used for marking the drone take-off and landing area, especially in open spaces or situations where clear indication of take-off and landing directions is required, thus improving the safety of drone take-off and landing. Preferably, the symbol 13 is V-shaped, and the specific shape of the symbol 13 is set according to requirements. Furthermore, the dimensions of the inner marking frame 11 are L1mm and the outer marking frame 12 are L2mm, where L2 > L1, and the actual distance between L1 and L2 is set according to requirements. In this embodiment, the landing platform 1 is 1.5m in size. Where L1=1000, L2=1500, and the distance between the inner sign frame 11 and the outer sign frame 12 is 250mm. The frame size of the inner sign frame 11 and the outer sign frame 12 is 20mm.
[0029] By setting the inner marking frame 11, outer marking frame 12, and V-shaped marking symbol 13 on the landing platform 1, clear markings can be provided for the take-off and landing of the drone. This also facilitates providing sufficient space for the drone's take-off and landing, ensuring a smoother and more precise take-off and landing. This, in turn, helps ensure the safety of the drone's take-off and landing.
[0030] Both the first folding frame 21 and the second folding frame 22 are hollow rectangular frame structures, and the pivot 23 is cylindrical. Both the first folding frame 21 and the second folding frame 22 are equipped with pivot rings 24. The pivot rings 24 are respectively located on the side of the frame of the first folding frame 21 and the second folding frame 22 parallel to the stop platform 1. At least four pivot rings 24 are provided. The pivot rings 24 of the first folding frame 21 and the second folding frame 22 are positioned correspondingly. The inner walls of the pivot rings 24 of both the first folding frame 21 and the second folding frame 22 are rotatably connected to the outer wall of the pivot 23.
[0031] By coordinating the folding frame 21, the folding frame 22, the pivot 23, and the pivot ring 24, the structure of the folding bracket 2 can be effectively simplified, the cost of the folding bracket 2 can be reduced, the folding convenience of the folding bracket 2 can be improved, and the stability and reliability of the folding bracket 2 in supporting the machine platform 1 can be greatly guaranteed.
[0032] Specifically, the folding frame 21 includes a supporting column 211, a supporting rod 212, a second supporting column 213, a second supporting rod 214, and a connecting column 215. Both ends of the supporting column 211 are connected to one end of the supporting rod 212 and the second supporting rod 214 respectively via the connecting column 215. The other ends of the supporting rod 212 and the second supporting rod 214 are connected to both ends of the supporting column 213 respectively via the connecting column 215. The supporting columns 211 and 213 are both perpendicular to the ground. The supporting rods 212 and 214 are both parallel to the ground. The tops of the supporting rods 212 and 215 are either attached to or separated from the bottom of the platform 1. The bottom of the supporting rod 212 and the top of the second supporting rod 214 are either attached to or separated from the top and bottom of the folding frame 22 respectively.
[0033] By setting up a folding frame 21, the structure of the folding frame 21 can be simplified, the cost of the folding frame 21 can be reduced, and the installation convenience between the folding frame 21 and the folding frame 22 can be improved.
[0034] The folding frame 22 includes three supporting columns 221, three supporting rods 222, four supporting columns 223, four supporting rods 224, and two connecting columns 225. Both ends of the three supporting columns 221 are connected to one end of the three supporting rods 222 and the four supporting rods 224 respectively via the connecting columns 225. The other ends of the three supporting rods 222 and the four supporting rods 224 are connected to both ends of the four supporting columns 223 respectively via the connecting columns 225. The three supporting columns 221 and the four supporting columns 223 are both perpendicular to the ground. The three supporting rods 222 and the four supporting rods 224 are both parallel to the ground. The top of the connecting column 225 is either flush with or separate from the bottom of the platform 1. The top of the three supporting rods 222 and the bottom of the four supporting rods 224 are either flush with or separate from the bottom of the first supporting rod 212 and the top of the second supporting rod 214, respectively. The height of the first connecting column 215 is less than the height of the second connecting column 225. This is to facilitate balancing the vertical errors between the folding frame 21 and the folding frame 22. Both the connecting column 215 and the connecting column 225 are columns.
[0035] By simplifying the structure of the folding bracket 22, its cost is reduced, and its installation convenience is improved. It can also work with the folding bracket 21 to achieve portable carrying and rapid assembly of the folding support 2. Furthermore, the different dimensions of the connecting column 215 and the connecting column 225 ensure the overall mechanical stability of the folding bracket 21 and folding bracket 22, and also improve their structural strength, guaranteeing the reliability and safety of their support for the machine platform 1.
[0036] Rotating rings 24 are respectively positioned at the center of support rod 212, support rod 214, support rod 222, and support rod 224. The rotating rings 24 are circular. Each support rod 212, support rod 214, support rod 222, and support rod 224 consists of two rods and their corresponding rotating rings 24. One end of each rod is connected to the outer wall of its corresponding rotating ring 24, and the two rods are aligned in a straight line. The other end of each rod is connected to either connecting post 215 or connecting post 225. The two rods and the rotating rings 24 are integrally formed. One end of the rotating shaft 23 is fitted with the inner wall of the rotating rings 24 of support rod 212 and support rod 222 from top to bottom. The other end of the rotating shaft 23 is fitted with the inner wall of the rotating rings 24 of support rod 214 and support rod 224 from bottom to top.
[0037] The rotating collar 24 ensures a smooth rotational connection between the folding bracket 2 and the rotating shaft 23. It also increases the contact area between the folding bracket 2 and the stop table 1, improving the tightness and reliability of their connection.
[0038] Preferably, the pivot ring 24 includes a pivot ring 241 and a pivot ring 242, which are respectively disposed on the frame of the folding frame 21 and the folding frame 22 parallel to the stop platform 1. When the folding support 2 does not include the reinforcing plate 3, the pivot ring 241 and the pivot ring 242 have the same height. When the folding support 2 includes the reinforcing plate 3, the height of the pivot ring 241 is less than the height of the pivot ring 242; the reinforcing plate 3 is disposed on the side of the pivot ring 241 of the folding frame 21 away from the folding frame 22. The reinforcing plate 3 is connected to the pivot ring 241 of the folding frame 21 by screws. The pivot ring 241 is provided with through holes corresponding to the screw holes of the reinforcing plate 3. The height of the pivot ring 241 + the height of the reinforcing plate 3 = the height of the pivot ring 242 = the height of the frame of the folding frame 21 or the folding frame 22 parallel to the stop platform 1.
[0039] By differentiating the design of the first and second pivot rings 241 and 242, the absence of the reinforcing disc 3 simplifies the structure of the folding bracket 2, reduces its manufacturing cost, and improves its assembly and disassembly efficiency. The inclusion of the reinforcing disc 3 facilitates better cooperation with the first and second folding frames 21 and the pivot 23, effectively strengthening the connection between them. This also enhances the overall stability and safety of the folding bracket 2, preventing the pivot 23 from detaching during assembly and disassembly, thus improving the user experience.
[0040] Specifically, when the folding bracket 2 includes the reinforcing disc 3, the heights of the first rotating ring 241 and the second rotating ring 242 are different. The height of the rotating shaft 23 is the distance from the top of the first rotating ring 241 of the first supporting rod 212 of the folding bracket 21 to the bottom of the first rotating ring 241 of the second supporting rod 214. The first rotating ring 241 is respectively located at the center of the first supporting rod 212 and the second supporting rod 214; the second rotating ring 242 is respectively located at the center of the third supporting rod 222 and the fourth supporting rod 224. Both the first rotating ring 241 and the second rotating ring 242 are circular. The first supporting rod 212, the second supporting rod 214, the third supporting rod 222, and the fourth supporting rod 224 are each composed of two rods and their corresponding rotating rings 24. The two rods of either support rod 212 or support rod 214 are connected to the rotating shaft ring 241 to form a groove. The groove opening on support rod 212 faces the stop platform 1, and the groove opening on support rod 214 faces the ground. Both reinforcing discs 3 are embedded in the groove. The diameter of the reinforcing disc 3 is the same as the outer diameter of the rotating shaft ring 241.
[0041] The grooves supporting rod 212 and rod 214 provide installation space for the reinforcing plate 3 and also help reduce the space occupied by the folding bracket 2. In addition, the grooves help reduce the consumption of raw materials, lower the cost of the device, and improve its aesthetics. The cylindrical shape of the reinforcing plate 3 helps ensure the safety of the user and avoids damage from bumps.
[0042] The folding bracket 2 also includes a reinforcing member 25. The inner wall of the reinforcing member 25 is rotatably attached to or detached from the outer wall of the rotating shaft 23. The reinforcing member 25 is attached to the inner wall of the folding secondary frame 22 of the folding bracket 2 by screws. The reinforcing member 25 is annular. At least two reinforcing members 25 are provided. Preferably, two reinforcing members 25 are provided. The two reinforcing members 25 are respectively provided at both ends of the rotating shaft 23; both reinforcing members 25 are respectively connected to the bottom of the support rod 222 and the top of the support rod 224 of the folding secondary frame 22 by screws. This is used to improve the tightness of the connection between the folding bracket 2 and the rotating shaft 23. The diameter of the end of the reinforcing member 25 away from the folding secondary frame 22 is less than the diameter of the end of the reinforcing member 25 close to the folding secondary frame 22.
[0043] By setting the reinforcing member 25, the connection stability of the folding bracket 2 before and after folding can be improved, thereby preventing excessive folding operation between the folding bracket 21 and the folding bracket 22 due to accidental collision, which would affect the user's safety. It can also make it easier to control the degree of folding and improve the flexibility of the folding bracket 2.
[0044] In this utility model, any helipad can include the low-cost folding helipad structure described in this embodiment. Based on the relevant structure and assembly relationship of the pivot 23 and reinforcing member 25 provided in this embodiment, the helipad also includes conventional components such as the helipad platform 1 and the support structure; since these are all prior art, they will not be described in detail here.
[0045] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
