A wind speed sensor and a control system are also arranged in the base 2. The wind speed sensor is connected to the control system by electrical signals, and the first driving part 501 is electrically connected to the control system.

[0073] In this embodiment, by setting a first connecting rod 5031, a second connecting rod 5032 and a support plate 5033, the first driving part 501 drives the first connecting rod 5031 to rotate, thereby driving the second connecting rod 5032 to rotate and driving the connecting shaft 504 to slide along the guide groove 5021. The support plate 5033 is pivotally connected to the connecting shaft 504, thereby improving the flexibility of the top plate 4 to flip. The structure is simple and easy to implement.

[0074] Among them, preferably, Figures 5 to 8The guide groove 5021 shown includes a first vertical groove 50211 arranged along the Y direction of the vehicle body, and a circular arc groove 50212 connected to the first vertical groove 50211. The circular arc groove 50212 extends from the middle part of the first vertical groove 50211 to the middle and upper part of the base 2. When the top plate 4 is in a closed state, the top plate 4 is parallel to the upper plane of the base 2, the connecting shaft 504 is arranged at the starting end of the first vertical groove 50211, and the guide rod 5034 and the connecting shaft 504 are arranged in the first vertical groove 50211 in correspondence with each other. When the top plate 4 is in a vertical state, the connecting shaft 504 moves to the intersection of the first vertical groove 50211 and the circular arc groove 50212, the guide rod 5034 is arranged at the top of the first vertical groove 50211, and a flow gap is provided between the top plate 4 and the base 2.

[0075] In this embodiment, by providing the guide groove 5021 with a first vertical groove 50211 and an arc groove 50212, when the top plate 4 is in a closed state, the guide rod 5034 and the connecting shaft 504 are respectively arranged in the first vertical groove 50211 with an upper and lower interval. In the closed state, the accommodating cavity can be a closed space to prevent external debris or rainwater from entering the base 2 and damaging the drone or the drone nest.

[0076] At the same time, when the first driving part 501 starts to drive the first connecting rod 5031 to rotate, the second connecting rod 5032 and the connecting shaft 504 rise a distance along the first slide groove 3041, and when the connecting shaft 504 reaches the intersection of the arc groove 50212 and the first vertical groove 50211, the top plate 4 is in a vertical state. In the vertical state, the drone can obtain an initial judgment of the external environment before taking off, thereby improving the take-off stability. When the first driving part 501 continues to rotate, the guide rod 5034 is placed on the top of the first slide groove 3041, and the connecting shaft 504 slides along the arc groove 50212 to the top of the arc groove 50212, and the top plate 4 is in a flipping state, at which time the top plate 4 extends along the Z direction of the vehicle body. By setting the flipping state, the lifting assembly 3 can be driven to rise after flipping, thereby protecting the lifting assembly 3.

When the top plate 4 is in a side-opening state, the connecting shaft 504 is disposed in the second vertical groove 50213, the guide rod 5034 is slidably disposed in the first vertical groove 50211, and the top plate 4 is disposed parallel to both sides of the base 2.

[0078] In this embodiment, the support plate 5033 is an L-shaped bent plate, and a second vertical groove 50213 is provided so that the first driving part 501 drives the first connecting rod 5031 to continue to rotate, thereby sliding the connecting shaft 504 located at the top of the arc groove 50212 downward along the second vertical groove 50213, thereby driving the support plate 5033 and the top plate 4 to move downward. Therefore, a through groove is provided on the side wall of the base 2 so that the support plate 5033 does not interfere with the base 2 during the downward movement.

[0079] In addition, if Figure 10 to Figure 11 As shown, an adjustment seat 505 is also provided on the connecting shaft 504, and a second driving unit 506 is provided on the adjustment seat 505; a straight rod 507 is provided at the bottom end of the support plate 5033, and a power output end of the second driving unit 506 is hingedly connected to the straight rod 507.

A position detector is provided on the top plate 4, and the position sensor is electrically connected to the control system; the second driving unit 506 is electrically connected to the control system.

[0080] As mentioned above, by setting the second driving part 506 on the adjustment seat 505, the second driving part 506 drives the support plate 5033 to rotate to adjust the angle between the support plate 5033 and the base 2, so as to be able to adjust the angle of the top plate 4 in time. When the connecting shaft 504 moves downward along the second vertical groove 50213, the top plate 4 gradually translates downward parallel to the outer side of the base 2 to avoid interference or collision during the movement of the top plate 4.

When the third driving part 305 drives the upper end of the scissor mechanism 303 to approach or move away, the two slide bars 308 slide along the slide groove 3041. By providing the slide bars 308, the upper and lower ends of the two scissor mechanisms 303 can be respectively arranged on the planes of the bottom plate 301 and the support plate 304, thereby improving the lifting strength. The scissor mechanism 303 is formed by connecting a plurality of straight rods 507 and a through shaft.

[0084] In addition, if Figures 7 to 9 As shown, the top plate 4 also has a supporting state; when the top plate 4 is in the supporting state, the top plate 4 is tilted and abutted against both sides of the support plate 304. The second driving unit 506 adopts a telescopic cylinder, and a pressure sensor is provided on the air path of the telescopic cylinder. In this embodiment, the angle between the support plate 5033 and the base 2 is adjusted by the second driving unit 506 so that the support plate 304 can lift the UAV to the upper part of the cargo box 1. The second driving unit 506 drives the top plate 4 to abut against both sides of the support plate 304, thereby forming support for the support plate 304 and protecting the scissor mechanism 303. In the case of strong external wind force, the stability of the support plate 304 is further improved, and the stability of the take-off and landing of the UAV is improved.
