LANDING DEVICE

Abstract

The present disclosure relates to a landing device capable of allowing an unmanned aerial vehicle to be accommodated in a compact manner. A landing device includes a first leg portion that is swingable with a first end portion on a main body side of an unmanned aerial vehicle as an axis; and a second leg portion that is detachably attached to a second end portion of the first leg portion such that the second leg portion extends in an axial direction of the first leg portion. The present disclosure can be applied to, for example, a drone including a camera at a bottom of a main body.

Description

Claims

1. A landing device comprising: a first leg portion that is swingable with a first end portion on a main body side of an unmanned aerial vehicle as an axis; anda second leg portion that is detachably attached to a second end portion of the first leg portion such that the second leg portion extends in an axial direction of the first leg portion.

2. The landing device according to claim 1, further comprising: an expansion and contraction link portion that constitutes a link mechanism together with the first leg portion, and lifts and lowers the first leg portion to which the second leg portion is attached.

3. The landing device according to claim 2, further comprising: an attachment member that is provided at the second end portion of the first leg portion and has a holding portion having a hollow tubular shape,wherein the second leg portion is fitted to an inner diameter of the holding portion.

4. The landing device according to claim 3, wherein the attachment member has an adjustment portion that adjusts the inner diameter such that a fitting portion of the second leg portion is fastened.

5. The landing device according to claim 4, wherein the holding portion has a gap at a portion in a circumferential direction, andthe adjustment portion adjusts the inner diameter by changing a width of the gap.

6. The landing device according to claim 5, wherein the holding portion has projection portions that project in a radial direction from both ends of the gap and face each other across the gap, andthe adjustment portion changes a width of the gap by a screw member that penetrates the projection portions across the gap.

7. The landing device according to claim 6, wherein the adjustment portion includes a lever that has a male screw portion screwed to a female screw portion that is formed in the through-hole penetrating the projection portions across the gap to be closer to a depth side than the gap.

8. The landing device according to claim 7, wherein the lever is a clamping lever.

9. The landing device according to claim 7, wherein the lever is a cam lever.

10. The landing device according to claim 4, wherein the attachment member further has a locking hole that locks a protrusion portion having a convex shape, which is provided to a fitting portion of the second leg portion.

11. The landing device according to claim 10, wherein the protrusion portion is pressed in a radial direction by an elastic body in a cylinder of the second leg portion formed in a hollow tubular shape to protrude to the fitting portion.

12. The landing device according to claim 2, wherein the expansion and contraction link portion expands and contracts by a linear actuator to lift and lower the first leg portion to which the second leg portion is attached.

13. The landing device according to claim 12, wherein the linear actuator includes a motor and a lead screw.
