DETAILED DESCRIPTION

[0033] The technical solutions in the embodiments of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.

[0034] like Figure 1 As shown, an embodiment of the utility model provides a waterproof cabin of an unmanned aerial vehicle, the unmanned aerial vehicle comprising:

[0035] A waterproof chamber 100, which is a container with an opening on the side. A door assembly 120 for closing the opening is provided at the opening of the waterproof chamber 100. A sliding platform 110 that moves along a straight line is also provided inside the waterproof chamber 100. When the drone takes off / landing, the sliding platform 110 moves to the outside of the waterproof chamber 100;

[0036] The centering part 200 arranged in the waterproof chamber 100 is used to move the drone to a preset position inside the waterproof chamber 100, wherein the centering part 200 includes a blocking rod 210, a centering rod 220 and a swinging part 230, the blocking rod 210 is horizontally fixed inside the waterproof chamber 100, the swinging part 230 is fixedly connected to the inner wall of the waterproof chamber 100, the swinging part 230 is located on both sides of the sliding platform 110, the swinging part 230 is fixedly connected to the centering rod 220 to drive the centering rod 220 to swing, and the blocking rod 210 and the centering rod 220 are vertically arranged.

[0037] In this embodiment, if Figure 1 and Figure 2As shown, when receiving the drone, one end of the sliding platform 110 slides out from the waterproof compartment 100, and part of the sliding platform 110 is located outside the waterproof compartment 100. The drone lands on the sliding platform 110, and the sliding platform 110 slides toward the inside of the waterproof compartment 100. When the drone moves to a preset position, the blocking rod 210 blocks the drone from continuing to slide along the sliding platform 110. At this time, the sliding platform 110 continues to move inward. In the process of the blocking rod 210 blocking the drone, the supporting foot of the drone is attached to the blocking rod 210, so that it is at a preset position in the moving direction of the sliding platform 110. When the sliding platform 110 moves to the starting point, the swinging part 230 is started, and the swinging part 230 The centering rod 220 is driven to swing toward the direction of the UAV. During the swinging process of the centering rod 220, the centering rod 220 pushes the UAV to move toward the middle. Since the centering rod 220 is arranged on both sides of the sliding platform 110, the two centering rods 220 can push the UAV to the position between the two centering rods 220 when working at the same time, thereby completing the centering work of the UAV and also playing the role of fixing the UAV. When releasing the UAV, the centering rod 220 releases the UAV, and the sliding platform 110 slides outward, and the UAV follows the sliding platform 110 to move to the outside of the waterproof bin 100. Since the opening of the sliding platform 110 is arranged on the side, the top of the waterproof bin 100 is in a sealed state. When it rains, rainwater will not fall into the interior of the waterproof bin 100.

[0038] The waterproof cabin of the drone disclosed in the embodiment of the utility model is equipped with a waterproof compartment 100 with an entrance and exit on the side to load the drone.
