It combines aerial photography, remote sensing technology and unmanned aerial vehicle technology, and can capture detailed images of the ground surface at high altitude, so as to generate high-precision geographic information data. It is usually used in the research on the integrated application of information technology and surveying and mapping technology. However, there are still some defects in the current surveying and mapping unmanned aerial vehicles, such as:

[0003] When the existing surveying and mapping unmanned aerial vehicle lands, it is easy to generate large vibrations, so that the surveying and mapping unmanned aerial vehicle is easy to cause a large impact on the bracket when landing, resulting in damage to the bracket. At the same time, the surveying and mapping unmanned aerial vehicle is easy to collide with the surveying and mapping camera during the landing process, thus affecting the subsequent surveying and mapping effect of the surveying and mapping unmanned aerial vehicle. Content of the Utility Model

[0004] The purpose of the utility model is to provide a surveying and mapping unmanned aerial vehicle capable of assisting in buffering when landing, so as to solve the problem that the surveying and mapping unmanned aerial vehicle is not easy to assist in buffering when landing proposed in the above background technique.

[0005] To achieve the above purpose, the utility model provides the following technical scheme: A surveying and mapping unmanned aerial vehicle capable of assisting in buffering when landing, including a surveying and mapping unmanned aerial vehicle body, fan blades, support legs and a camera. Fan blades are arranged on both sides of the surveying and mapping unmanned aerial vehicle body. Support legs are arranged at the bottom end of the surveying and mapping unmanned aerial vehicle body. A camera is arranged on one side of the bottom end of the surveying and mapping unmanned aerial vehicle body close to the support legs. Auxiliary buffer mechanisms are symmetrically distributed at the bottom ends of the support legs. The auxiliary buffer mechanism includes a fixed frame and a fixed block. A fixed frame is arranged at the bottom end of the support leg. Symmetrically distributed fixed blocks are welded and connected inside the two fixed frames.

[0006] Preferably, a T-shaped block extending to the outside of the fixed frame is arranged inside the fixed block. A connecting seat is welded and connected to one end of the T-shaped block. An anti-slip pad is arranged at the bottom end of the connecting seat.

[0007] Preferably, clamping blocks extending to the inside of the fixed block are arranged on both sides of the T-shaped block. Spring dampers extending to the outside and connected to the T-shaped block are arranged on both sides inside the fixed block. Symmetrically distributed U-shaped elastic pieces are arranged between the fixed frame and the connecting seat.

[0008] Preferably, protection mechanisms are arranged at the top ends of the two fixed frames. The protection mechanism includes a connecting block, a mounting rod, a protection plate, a rotating rod, a bolt and a locking groove. Connecting blocks are arranged at the top ends of the two fixed frames.

[0009] Preferably, an installation rod extending to the outside is arranged inside the connecting block, and a protection plate is welded and connected to one end of the installation rod.

One side of the rotating rod is threadedly connected with a bolt extending into the fixed frame, and a locking groove is formed on one side of the installation rod close to the rotating rod.

[0011] Compared with the prior art, the beneficial effects of the present utility model are as follows: for the surveying and mapping unmanned aerial vehicle capable of auxiliary buffering during landing, when the surveying and mapping unmanned aerial vehicle body lands, first, the anti-slip pad fits with the ground. At the same time, after the connecting seat is impacted, it moves, so that the impact force of the surveying and mapping unmanned aerial vehicle body landing can be offset through the cooperation of the U-shaped elastic piece, the spring damper and the clamping block, enabling auxiliary buffering when the surveying and mapping unmanned aerial vehicle body lands. The protection plate is driven by the installation rod to be engaged with the connecting block, then the rotating rod is rotated to be locked with the locking groove, and then the bolt can be rotated to be locked with the fixed frame, and at the same time, the rotating rod can be fixed, so that the protection plate can be installed below the camera, so that the surveying and mapping unmanned aerial vehicle can have a good protection effect during surveying.

[0012] 1. For the surveying and mapping unmanned aerial vehicle capable of auxiliary buffering during landing, when the surveying and mapping unmanned aerial vehicle body lands, first, the anti-slip pad can fit with the ground. At the same time, after the connecting seat is impacted, it moves, so that the connecting seat can drive the T-shaped block to move when moving. At the same time, the T-shaped block can drive the clamping blocks on both sides to move when moving, so that the clamping blocks can be stuck into different positions. Since the clamping blocks are made of rubber material, when being impacted and extruded and deformed into different engaging grooves, the impact force can be offset, thereby avoiding large vibrations of the surveying and mapping unmanned aerial vehicle. At the same time, the T-shaped block can drive the spring damper to be stretched and extruded when moving, so that the impact force of landing can be buffered again. And when the connecting seat moves, it can squeeze the U-shaped elastic piece, so that the cooperation of the U-shaped elastic piece, the spring damper and the clamping block can offset the impact force of the surveying and mapping unmanned aerial vehicle body landing, enabling auxiliary buffering when the surveying and mapping unmanned aerial vehicle body lands, avoiding damage to the surveying and mapping unmanned aerial vehicle body caused by large vibrations generated, and enabling the surveying and mapping unmanned aerial vehicle to have a good auxiliary buffering effect during surveying;

[0013] 2. For the surveying and mapping unmanned aerial vehicle capable of auxiliary buffering during landing, the protection plate is driven by the installation rod to be engaged with the connecting block, and then the rotating rod is rotated, so that the rotating rod can be locked with the locking groove when rotating. Then the bolt can be rotated, so that the bolt can be locked with the fixed frame when rotating, and at the same time, the rotating rod can be fixed, so that the protection plate can be installed below the camera, avoiding damage to the camera caused by the splashing of gravel or impurities when the surveying and mapping unmanned aerial vehicle body lands, so that the surveying and mapping unmanned aerial vehicle can have a good protection effect during surveying.

The auxiliary buffering mechanism 5 includes a fixed frame 501 and a fixed block 502. A fixed frame 501 is arranged at the bottom end of the support leg 3, and symmetrically distributed fixed blocks 502 are welded and connected inside the two fixed frames 501. A T-shaped block 503 extending to the outside of the fixed frame 501 is arranged inside the fixed block 502. One end of the T-shaped block 503 is welded and connected with a connecting seat 504. An anti-slip pad 505 is arranged at the bottom end of the connecting seat 504. Clamping blocks 506 extending to the inside of the fixed block 502 are arranged on both sides of the T-shaped block 503. Spring dampers 507 extending to the outside and connected with the T-shaped block 503 are arranged on both sides inside the fixed block 502. Symmetrically distributed U-shaped elastic pieces 508 are arranged between the fixed frame 501 and the connecting seat 504.

[0021] Refer to Figure 1 、 Figure 2 and Figure 3 It can be seen that when the surveying and mapping UAV body 1 lands, first, the anti-slip pad 505 fits with the ground. At the same time, after the connecting seat 504 is impacted and moves, the cooperation of the U-shaped elastic piece 508, the spring damper 507 and the clamping block 506 can offset the impact force of the surveying and mapping UAV body 1 when landing, so as to assist in buffering the surveying and mapping UAV body 1 when landing.

[0022] Refer to Figure 1 、 Figure 2 and Figure 4 It can be seen that protective mechanisms 6 are arranged at the top ends of the two fixed frames 501. The protective mechanism 6 includes a connecting block 601, a mounting rod 602, a protective plate 603, a rotating rod 604, a bolt 605 and a locking groove 606. Connecting blocks 601 are arranged at the top ends of the two fixed frames 501. A mounting rod 602 extending to the outside is arranged inside the connecting block 601. One end of the mounting rod 602 is welded and connected with a protective plate 603.

A locking groove 606 is opened on one side of the mounting rod 602 close to the rotating rod 604.

[0023] Refer to Figure 1 、 Figure 2 and Figure 4It can be seen that by driving the protection plate 603 through the installation rod 602 to engage with the connection block 601, and then rotating the rotating rod 604 to lock it with the locking groove 606, the rotatable bolt 605 can be locked with the fixed frame 501, and at the same time, the rotating rod 604 can be fixed, so that the protection plate 603 can be installed below the camera 4, so that the mapping UAV can have a better protection effect during mapping.

[0024] In summary, the mapping UAV is a UAV specifically used for geographic information collection. When the mapping UAV body 1 lands, first, the anti-slip pad 505 fits with the ground. At the same time, when the connection seat 504 moves after being impacted, it can drive the T-shaped block 503 to move. When the T-shaped block 503 is impacted and squeezed and deformed into different engaging grooves, it can offset the impact force, thereby avoiding large vibrations of the mapping UAV. At the same time, when the T-shaped block 503 moves, it can drive the spring damper 507 to stretch and squeeze, so that the impact force of landing can be buffered again. And when the connection seat 504 moves, it can squeeze the U-shaped elastic piece 508, so that the cooperation of the U-shaped elastic piece 508, the spring damper 507 and the clamping block 506 can offset the impact force of the mapping UAV body 1 landing, so that it can assist in buffering when the mapping UAV body 1 lands, avoiding damage to the mapping UAV body 1 caused by large vibrations, and enabling the mapping UAV to have a better auxiliary buffering effect during mapping.
