[0032] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installation", "connection" and "connection" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0033] like Figure 1 and Figure 2 As shown, the automatic airport skylight opening and closing mechanism provided by the embodiment of the utility model includes: a frame 100, a movable part 200, a driving part 300, a plurality of swing arms 400 and a plurality of skylight petals 500; the movable part 200 is slidably matched with the frame 100, and the movable part 200 is transmission-connected with the driving part 300; a plurality of skylight petals 500 are arranged at intervals around the frame 100, and each skylight petal 500 is connected to at least one swing arm 400; the middle parts of the plurality of swing arms 400 are respectively slidably hinged to the frame 100, and the ends of the plurality of swing arms 400 away from the skylight petals 500 are respectively hinged to the movable part 200.

[0034] The driving device 300 can drive the movable part 200 to slide relative to the frame 100, and the movable part 200 can push and pull multiple swing arms 400, and the swing arms 400 can drive the skylight petals 500 to move. Specifically, when the movable part 200 pushes the swing arm 400, the swing arm 400 slides relative to the frame 100 and swings outward, thereby pushing multiple skylight petals 500 to swing outward and disperse from each other, which can not only avoid motion interference caused by the opening action, but also increase the size of the opening formed between the multiple skylight petals 500, thereby ensuring that the drone can take off and land smoothly through the opened skylight. When the movable part 200 pulls the swing arm 400, the swing arm 400 slides relative to the frame 100 and swings inward, thereby pulling multiple skylight petals 500 to swing inward and converge, and any two adjacent skylight petals 500 are relatively closed, so that the multiple skylight petals 500 can be aggregated more tightly.

[0035] like Figure 1 As shown, in the embodiment of the utility model, a slide groove 401 is provided in the middle of the swing arm 400; a sliding shaft 101 is installed on the frame 100, and the sliding shaft 101 is matched in the slide groove 401, so as to realize the sliding hinge connection between the middle of the swing arm 400 and the frame 100. When the movable part 200 can push and pull the swing arm 400, the swing arm 400 slides along the slide groove 401 relative to the sliding shaft 101, and the swing arm 400 can swing around the sliding shaft 101. During the opening process, multiple skylight petals 500 swing outward and move in a direction of mutual dispersion, and during the closing process, multiple skylight petals 500 swing inward and move in a direction of convergence, which improves the compactness of the structure and can avoid motion interference of the skylight petals 500 during the opening process.

[0036] Furthermore, the swing arm 400 bends outward from one end hinged to the movable part 200 to one end connected to the skylight flap 500, thereby increasing the opening size between the multiple skylight flaps 500 in the open state and preventing the skylight flaps 500 from interfering with the take-off and landing of the drone.

[0037] Furthermore, the frame 100 is connected with a guide member 102, and the movable member 200 is slidably matched with the guide member 102. The guide member 102 is configured as a rod or a guide rail, and the movable member 200 can be configured as a ring member or a rectangular frame. The movable member 200 is slidably matched with the guide member 102, thereby ensuring that the movable member 200 can slide smoothly relative to the frame 100.

[0038] like Figure 1 and Figure 2 As shown, in an optional embodiment, the driving component 300 may be a telescopic cylinder, which drives the movable component 200 to slide back and forth relative to the frame 100, thereby driving the opening and closing of the plurality of skylight petals 500.

[0039] In this embodiment, the driving device 300 includes: a lead screw 301 and a power source 302, the lead screw 301 is connected to the power source 302 by transmission, and the lead screw 301 is matched with the movable part 200. The power source 302 can be a stepping motor, or the power source 302 is connected to the reducer by an electric motor, and is connected to the lead screw 301 by transmission through the reducer, and the rotating lead screw 301 can cooperate with and drive the movable part 200 to slide relative to the frame 100. On the one hand, when the movable part 200 slides relative to the frame 100, the skylight petals 500 can be driven to open and close through the swing arm 400; on the other hand, when the lead screw 301 stops rotating, the lead screw 301 can lock the movable part 200, so that the plurality of skylight petals 500 remain in an open or closed state.

[0040] like Figure 1 and Figure 2 As shown, the drone automatic airport provided by the embodiment of the utility model comprises: a cabin shell 600 and the automatic airport skylight opening and closing mechanism described in the above embodiment; the cabin shell 600 surrounds and connects the frame 100; in the closed state, the plurality of skylight petals 500 are relatively closed and cover the cabin shell 600. The drone automatic airport has the technical effects of the above automatic airport skylight opening and closing mechanism, which will not be described in detail here.

[0041] In the embodiment of the utility model, the skylight petals 500 are connected with sealing strips; in the closed state, the sealing strips are sandwiched between any two skylight petals 500. During the closing process, the plurality of skylight petals 500 swing inward with the swing arm 400 and deviate obliquely downward, so that the sealing strips can be pressed more tightly between the two skylight petals 500.

[0042] like Figure 1 As shown, the open end of the cabin shell 600 is provided with a plurality of raised edges 601, and the plurality of raised edges 601 are arranged at intervals along the circumference of the cabin shell 600; the skylight petals 500 are provided with concave arc portions 501, and in the closed state, the concave arc portions 501 of the plurality of skylight petals 500 correspond one-to-one with the plurality of raised edges 601.

[0043] The open end of the cabin shell 600 is provided with a plurality of recessed edges 602, and the plurality of recessed edges 602 are arranged at intervals along the circumference of the cabin shell 600; the skylight petal 500 is provided with a convex arc portion 502, and in the closed state, each recessed edge 602 is fitted with at least one convex arc portion 502.

[0044] By matching the concave arc portion 501 with the convex edge 601 and matching at least one convex arc portion 502 within the concave edge 602, it can be ensured that multiple skylight petals 500 fit tightly against the opening edge of the cabin shell 600, thereby ensuring a stable relative position and a good sealing effect.

[0045] Furthermore, in the closed state, the cross-section of the structure spliced ​​by the plurality of skylight petals 500 is configured as a circle or a polygon; the middle of the skylight petals 500 bulges outward along the sliding direction of the movable part 200. In the closed state, the area enclosed by the plurality of skylight petals 500 is relatively large, increasing the accommodation space of the drone automatic airport; in the open state, the middle of the skylight petals 500 bulges outward to form a larger opening size, which is convenient for the take-off and landing of the aircraft.

[0046] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model, rather than to limit it. Although the utility model has been described in detail with reference to the aforementioned embodiments, ordinary technicians in this field should understand that they can still modify the technical solutions recorded in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents. However, these modifications or replacements do not make the essence of the corresponding technical solution deviate from the scope of the technical solution of the embodiments of the utility model.
