Description

Technical Field

[0001] This invention relates to the field of unmanned aerial vehicles (UAVs), and more particularly to a UAV landing pad. Background Technology

[0002] Drones need a landing surface to land, and drone helipads were created to serve this purpose. Traditional drone helipads are divided into integrated types, manually folding types, and hangar types. An integrated helipad is a flat surface that cannot be folded, and its top surface area is the parking area. Manually folding helipads are an improvement on the integrated type by adding folding hinges. Hangar types are enclosed spaces to accommodate and protect drones. However, integrated helipads are inconvenient to carry, manually folding helipads lack automation and are all folded in one go, which cannot maximize the folded area, while hangar types offer limited parking area and are bulky. Summary of the Invention

Detailed Implementation

[0015] To better understand the purpose, structure, and function of this invention, the following detailed description of a specific embodiment of the "Unmanned Aerial Vehicle Landing Pad" of this invention is provided in conjunction with the accompanying drawings.

[0016] See Figures 1-3 and Figures 8-9 In this embodiment, the UAV landing pad of the present invention includes a fixed plate 100, a first folding plate 101, an auxiliary connecting plate 102, and a second folding plate 103 located on the same plane. A first transmission assembly 200 and a second transmission assembly 300 are disposed on the bottom surface of the fixed plate 100. The fixed plate 100 has a first side 1001 and a second side 1002 that are perpendicular to each other. The first folding plate 101 has a third side 1011 and a fourth side 1012 that are perpendicular to each other. The auxiliary connecting plate 102 has a fifth side 1021 that is perpendicular to each other. The second folding plate 103 has a seventh side 1031 and an eighth side 1032 that are perpendicular to each other; the second side 1002 is hinged to the third side 1011, the fourth side 1012 is hinged to the fifth side 1021, the sixth side 1022 is hinged to the seventh side 1031, and the eighth side 1032 is spliced ​​to the first side 1001; the second side 1002 and the seventh side 1031 are on the same straight line, and the fourth side 1012 and the eighth side 1032 are on the same straight line; at this time, the apron is... Figure 8 The helipad is in its fully unfolded state. The first transmission assembly 200 is connected to the bottom surface of the first folding plate 101 via the first C-shaped rocker arm 400; the first transmission assembly 200 can drive the first C-shaped rocker arm 400 to fold the first folding plate 101 to the top plane of the fixed plate 100, and drive the auxiliary connecting plate 102 to fold to the top plane of the second folding plate 103, thus completing the first fold; at this time, the helipad is... Figure 9 The first fold. The second transmission assembly 300 is connected to the bottom surface of the second folding plate 103 via the second C-shaped rocker arm 500; the second transmission assembly 300 can drive the second C-shaped rocker arm 500 to move the second folding plate 103 and the auxiliary connecting plate 102 folded onto the second folding plate 103, together folding them to the top plane of the fixed plate 100 to complete the second fold; at this time, the apron is... Figure 10 The second folded state. In this embodiment, the helipad can automatically fold / unfold twice. When the helipad is folded twice, its volume is minimized, making it highly portable. When it is unfolded twice, its top surface area is maximized, greatly increasing the helipad's parking area.

[0017] It should be noted that, in this embodiment, in order to achieve the best secondary folding effect, the helipad preferably has one fixed plate 100, two first folding plates 101, four auxiliary connecting plates 102, and two second folding plates 103. With this arrangement, the unfolded area can be about four times the area of ​​the top plane when folded, achieving the maximum unfolding effect. However, in other embodiments, the number and shape of the fixed plate 100, the first folding plates 101, the auxiliary connecting plates 102, and the second folding plates 103 can be changed, as long as the design requirements for folding on both sides are met. Furthermore, the hinge in the above embodiment is preferably a hinge, but other forms of hinge can also be used, as long as the hinge can be unfolded flat and folded easily.

[0018] See further Figure 2 In this embodiment, a first slide rail 104 is provided on the bottom surface of the first folding plate 101. The first movable end 401 of the first C-shaped rocker 400 is slidably connected to the first folding plate 101 through the first slide rail 104. This allows the first folding plate 101 to be folded / unfolded smoothly, preventing the first folding plate 101 from getting stuck or stopping during folding / unfolding. At the same time, a buffer stroke is reserved for the first folding / unfolding to prevent the components from being damaged due to rigid force between the first C-shaped rocker 400 and the first folding plate 101. Damage; The bottom surface of the second folding plate 103 is provided with a second slide rail 105, and the second movable end 501 of the second C-shaped rocker 500 is slidably connected to the second folding plate 103 through the second slide rail 105. This allows the second folding plate 103 to be folded / unfolded smoothly, preventing the second folding plate 103 from getting stuck or stopping during folding / unfolding. At the same time, it provides a buffer stroke for the second folding / unfolding to prevent damage to the components between the second C-shaped rocker 500 and the second folding plate 103 due to rigid force.

[0019] Furthermore, in some implementations, the first movable end 401 has a first roller 4011, which can roll on the first slide rail 104 to make the first movable end 401 of the first C-shaped rocker 400 slide more sensitively on the first slide rail 104; the second movable end 501 has a second roller 5011, which can roll on the second slide rail 105 to make the second movable end 501 of the second C-shaped rocker 500 slide more sensitively on the second slide rail 105.

The first power output part 201 drives the first rotating shaft 202 to rotate, and the first rotating shaft 202 drives the first rotating end 402 of the first C-shaped rocker 400 to rotate, thereby driving the first movable end 401 of the first C-shaped rocker 400 to swing, so as to drive the first folding plate 101 to fold / unfold. The second transmission assembly 300 includes a second power output part 301 and a second rotating shaft 302. Both ends of the second rotating shaft 302 are fitted with second bearing bases 307. The second bearing bases 307 are fixed to the bottom surface of the fixed plate 100. The second rotating shaft 302 can rotate relative to the fixed plate 100. The second rotating end 502 of the second C-shaped rocker 500 is fitted and fixed on the second rotating shaft 302. The second power output part 301 drives the second rotating shaft 302 to rotate. The second rotating shaft 302 drives the second rotating end 502 of the second C-shaped rocker 500 to rotate, thereby driving the second movable end 501 of the second C-shaped rocker 500 to swing, so as to drive the second folding plate 103 to fold / unfold.

[0021] For more details, see Figure 4 and Figure 5In this embodiment, the first power output unit 201 includes a first base 2011 fixed to the bottom surface of the fixing plate 100. A first motor 2012 is disposed on the first base 2011. The drive end of the first motor 2012 is connected to a first drive gear 2013.

The first driven gear 2014 is meshed with the first driving gear 2013 so that the first motor 2012 can drive the two first C-shaped rocker arms 400 to swing synchronously, preventing the two sides from being out of sync during the first folding process. Two second rotating shafts 302 are arranged in parallel on the bottom surface of the fixed plate 100. A second synchronous gear 3021 and a second C-shaped rocker arm 500 are sleeved and fixed on each of the second rotating shafts 302.

[0024] See further Figure 4 and Figure 5 In this embodiment, to ensure that the first folding and the second folding processes are performed in sequence and do not cause conflict, a first sensor 206 is provided on both the first front stop 204 and the first rear stop 205. When the first abutting member 403 abuts against the first front stop 204 / first rear stop 205, the first sensor 206 is triggered to sense that the first folding plate 101 has been folded / unfolded. A second sensor 306 is provided on both the second front stop 304 and the second rear stop 305. When the second abutting member 503 abuts against the second front stop 304 / second rear stop 305, the second sensor 306 is triggered to sense that the second folding plate 103 has been folded / unfolded.

When deployment is required, a command can be sent to the control unit via remote control. The control unit then sends a command to the second motor 3012, which starts working to perform the first deployment. When the second sensor 306 detects that the first deployment is complete, it sends a feedback command to the control unit, which then controls the second motor 3012 to stop working. The control unit then sends a command to the first motor 2012, which starts working to perform the second deployment. When the first sensor 206 detects that the second deployment is complete, it sends a feedback command to the control unit, which then controls the first motor 2012 to stop working, and the deployment is complete.
