Description

Technical Field

[0001] The utility model relates to the technical field of unmanned aerial vehicles, in particular to an unmanned aerial vehicle with a supporting tripod. Background Art

[0002] The drone tripod is a derivative product of the drone, and its function is to support the drone when it takes off and lands.

The installation is complicated in actual use and it is often necessary to install it before reaching the flight area. At the same time, there is no shock-absorbing device inside. When the drone lands, the tripod at the bottom of the drone directly contacts the ground, causing the impact force generated to be transmitted to the inside of the drone, which may cause damage to the inside of the drone.

[0011] Compared with the prior art, the utility model has the following beneficial effects:

[0012] 1. The drone with a supporting tripod is installed by placing the drone body above a fixed chassis, passing the first strap through the outer wall of the drone body to the top of the drone body, passing the second strap through the fixed block on the top of the first strap, and pulling the second strap to move the ratchet groove below the fixed ratchet.

[0022] In a preferred embodiment, a rectangular groove is provided on the outer wall of the fixing block 8, and the rectangular groove passes through the fixing block 8. The shape of the rectangular groove on the outer wall of the fixing block 8 is adapted to the shape of the strap 2 4. In the above structure, by passing the strap 2 4 through the square groove on the outer wall of the fixing block 8, it passes through the square groove on the outer wall of the fixing block 8 to reach the other side of the fixing block 8. At this time, pulling the strap 2 4 can adjust the length of the strap 2 4 passing through the fixing block 8, so that the tightness between the strap 2 4 and the strap 1 3 can be adjusted.

[0023] In a preferred embodiment, the top of the pull rod 10 passes through the fixed block 8, and the number of the pull rods 10 and the spring 11 is two, the two pull rods 10 and the spring 11 are symmetrically distributed inside the fixed block 8, and the tops of the two pull rods 10 are provided with connecting plates to connect the two pull rods 10. In the above structure, by pulling the connecting plate on the top of the pull rod 10 upward, the two pull rods 10 are driven to move upward, and then the fixed ratchet 9 is driven to move upward, so that the spring 11 on the top of the fixed ratchet 9 contracts.

[0024] In a preferred embodiment, the fixed ratchet 9 is located above the ratchet groove 12, and the fixed ratchet 9 is adapted to the size of the ratchet groove 12. In the above structure, the ratchet groove 12 at the top of the strap 2 4 is moved by pulling the strap 2 4, and the ratchet groove 12 is moved so that the fixed ratchet 9 is squeezed upward by the movement of the ratchet groove 12, so that the strap 2 4 can be pulled. When the strap 2 4 stops pulling, the fixed ratchet 9 is bounced between the ratchet grooves 12 by the downward elastic force of the spring 11, and the ratchet direction of the fixed ratchet 9 and the ratchet direction of the ratchet groove 12 make the ratchet groove 12 fixed by the fixed ratchet 9.

[0026] In a preferred embodiment, the top of the limiting column 13 penetrates the top of the fixed shell 6, and an extension ring is provided on the top of the limiting column 13. The diameter of the extension ring on the top of the limiting column 13 is larger than the through hole through which the limiting column 13 penetrates the fixed shell 6. In the above structure, the limiting column 13 is limited by the extension ring on the top of the limiting column 13, so that the limiting column 13 cannot be separated from the fixed shell 6.

[0027] Working principle: when using the device, the drone body 1 is placed above the fixed chassis 2, and the strap 1 3 is placed on the top of the drone body 1, and the strap 2 4 is passed through the square groove on the outer wall of the fixed block 8, so that it passes through the square groove on the outer wall of the fixed block 8 to reach the other side of the fixed block 8, and the ratchet groove 12 at the top of the strap 2 4 is moved by pulling the ratchet groove 12, and the ratchet groove 12 squeezes the fixed ratchet 9 upward through the movement of the ratchet groove 12, so that the strap 2 4 can be pulled, and when the strap 2 4 stops pulling, the fixed ratchet 9 is bounced into between the ratchet grooves 12 by the downward elastic force of the spring 11, and the ratchet direction of the fixed ratchet 9 and the ratchet direction of the ratchet groove 12 make the ratchet groove 12 be fixed The ratchet The tooth 9 is fixed. At this time, the drone body 1 is fixed on the top of the fixed chassis 2 by the strap 1 3 and the strap 2 4. Then, the drone body 1 is installed. The drone body 1 can be manipulated to make it fly. When the drone body 1 is landing, the fixed chassis 2 is facing downward, and the buffer pad 7 is in contact with the bottom surface. When the buffer pad 7 is in contact with the ground, the buffer pad 7 moves upward, thereby driving the bottom of the elastic steel 15 to move upward, so that the two ends of the elastic steel 15 expand, and drive the two sliding blocks 16 to move to both sides. At the same time, due to the upward movement of the buffer pad 7, the limit column 13 is driven to move upward, so that the spring 2 14 contracts, and the impact force during landing is absorbed by the spring 2 14 and the elastic steel 15, so that the impact force on the drone body 1 is reduced.
