Unmanned aerial vehicle and waterproof container
Provided is an unmanned aerial vehicle including a waterproof container including: a container main body having an opening in a bottom surface defined in a landed state of the unmanned surface aerial vehicle; a waterproof door mounted to the container main body so as to open outward and close the opening; an elastic seal, which is interposed between the container main body and the waterproof door, and is configured to close the waterproof door in a liquid-tight manner; a first door-closing mechanism configured to retain a first door-closing state of the waterproof door; and a second door-closing mechanism configured to prevent movement of the waterproof door in a door-opening direction in a second door-closing state in which the waterproof door has been pushed in a direction of resisting against an elastic force of the elastic seal from the first door-closing state.
1. An unmanned aerial vehicle comprising a waterproof container configured to accommodate a package,
the waterproof container including:
a container main body having an opening in a bottom surface;
a waterproof door mounted to the container main body so as to translate outward and downward so as to open and close the opening;
an elastic seal, which is interposed between the container main body and the waterproof door, and which is configured to close the waterproof door in a liquid-tight manner;
a first door-closing mechanism configured to retain a first door-closing state of the waterproof door; and
a second door-closing mechanism configured to prevent movement of the waterproof door in a door-opening direction in a second door-closing state in which the waterproof door has been pushed in a direction of further compressing an elastic force of the elastic seal from the first door-closing state, when a landing surface contacts the waterproof door when the unmanned aerial vehicle is provided in a landed state.
2. The unmanned aerial vehicle according to claim 1 , wherein the waterproof door is a double door including a first door and a second door.
3. The unmanned aerial vehicle according to claim 2 , wherein the elastic seal is also interposed between the first door and the second door.
4. The unmanned aerial vehicle according to claim 1 , wherein the first door-closing mechanism and the second door-closing mechanism are included in a locking mechanism having a plurality of locking levels.
5. The unmanned aerial vehicle according to claim 1 , further comprising a pressure adjustment valve mounted to the container main body.
6. The unmanned aerial vehicle according to claim 1 , wherein the waterproof door includes a float.
7. The unmanned aerial vehicle according to claim 1 ,
wherein the waterproof door includes:
a first-side end portion extending along a rotation shaft for opening and closing; and
a second-side end portion located on a side opposite to the first-side end portion, and
wherein an outer surface of the waterproof door is a surface generated by translation of the rotation shaft and is inclined toward the first-side end portion.
8. The unmanned aerial vehicle according to claim 7 , wherein the outer surface is a curved surface.
9. The unmanned aerial vehicle according to claim 1 , further comprising a parachute.
10. The unmanned aerial vehicle according to claim 1 , further comprising a radio configured to perform at least one of transmission or reception of signals.
