Description

Technical Field

[0001] The utility model relates to the technical field related to unmanned aerial vehicles, in particular to an anti-collision unmanned aerial vehicle for three-dimensional modeling engineering surveying and mapping. Background Art

[0002] Unmanned aerial vehicles, abbreviated as UAVs, are unmanned aircraft controlled by radio remote control equipment and self-contained program control devices, or operated completely or intermittently autonomously by on-board computers. UAVs are only used for three-dimensional modeling engineering surveying and mapping in some environments with relatively harsh terrain.

[0003] However, in the process of 3D modeling engineering surveying and mapping, due to the harsh terrain being surveyed, obstacles are inevitable during the surveying and mapping process. UAVs often cause friction or collision with obstacles. When colliding, the UAV will be damaged, thereby reducing work efficiency and increasing the cost of use. For this reason, we propose an anti-collision UAV for 3D modeling engineering surveying and mapping. Utility Model Content

[0004] The purpose of the utility model is to provide an anti-collision drone for three-dimensional modeling engineering surveying and mapping, so as to solve the problem raised in the above-mentioned background technology that when a collision occurs, the drone will be damaged, thereby reducing work efficiency. In order to achieve the above-mentioned purpose, the utility model provides the following technical solutions: an anti-collision drone for three-dimensional modeling engineering surveying and mapping, comprising a drone body and an articulated frame, the top of the drone body is fixedly connected to an inflatable airbag, the bottom of the drone body is fixedly connected to a connecting frame, the bottom of the connecting frame is fixedly connected to a hexagonal prism, the bottom of the articulated frame is fixedly connected to an articulated seat and the articulated frame is arc-shaped, the other side of the articulated seat is articulated with a telescopic rod, the side surface of the telescopic rod is sleeved with a spring, one end of the spring is fixedly connected to the other side of the articulated seat, and the other end of the spring is fixedly connected to one side of the hexagonal prism. When in use When the anti-collision drone is used for 3D modeling engineering surveying, the drone body and the power parts drive the drone to fly as a whole. During the flight, when it is about to hit a wall or an obstacle, the drone body is controlled to bend the articulated frame downward through the connecting seat, and the spring and the telescopic rod are pressed. Since the telescopic rod is hinged at both ends, when the articulated frame is bent downward through the connecting seat, the spring can be limited to prevent elastic deformation of the spring. At the same time, the power parts are closed, and the four articulated frames are folded inward to shrink. At the same time, the inflatable airbag opens. When it hits an obstacle, the airbag is used for cushioning to avoid damage to the drone body.

[0005] Further preferably, four smooth grooves are opened on the side surface of the connecting frame, and the four smooth grooves are distributed in a circular array, and an extension arm is fixedly connected in each of the smooth grooves, wherein two opposite extension arms are located on top of the other two opposite extension arms, and the extension arms are arc-shaped.

[0006] Further preferably, the other side of each of the extension arms is fixedly connected to a connection seat, the articulated frame is hinged to the connection seat, and the other side of the articulated frame is fixedly connected to an extension plate.

[0007] Further preferably, a power piece is fixedly connected to the top of the extension plate, and support plates are respectively fixedly connected to two sides of the hexagonal prism, and the two support plates are symmetrically distributed on two sides of the hexagonal prism, and the drone is driven to fly by the power piece.

[0008] Further preferably, two sides of the hexagonal prism are respectively fixedly connected with support plates, and the two support plates are symmetrically distributed on two sides of the hexagonal prism. The hexagonal prism is hexagonal and can be folded and stretched by a spring, so that the drone has high flexibility.

[0009] Further preferably, a triangular seat is fixedly connected to the bottom of each support plate, and a protective airbag is fixedly connected to the bottom of the triangular seat. The triangular seat is in the shape of a triangle. When using the anti-collision drone for three-dimensional modeling engineering surveying and mapping, when the drone flies too low and hits an obstacle, the power parts cannot be opened in time, and the drone will fall to the ground and cause damage. Therefore, this patent designs a triangular seat and a protective airbag. The triangle has stability and can make the drone have a higher balance. At the same time, when the power parts cannot be opened in time, the protective airbag is opened to prevent the bottom of the drone from falling to the ground and causing damage.

[0010] Compared with the prior art, the utility model has the following beneficial effects:

[0011] In the utility model, when the anti-collision drone for three-dimensional modeling engineering surveying is used, the drone body and the power component drive the drone as a whole to fly. During the flight, when it is about to hit a wall or an obstacle, the drone body is controlled to bend the articulated frame downward through the connecting seat, and the spring and the telescopic rod are pressed. Since the telescopic rod is hinged at both ends, when the articulated frame is bent downward through the connecting seat, the spring can be limited to prevent the spring from elastic deformation. At the same time, the power component is closed, and the four articulated frames are folded inward to shrink. At the same time, the inflatable airbag is opened. When it hits an obstacle, the airbag is used for cushioning to avoid damage to the drone body.

[0012] In the utility model, when the anti-collision drone for three-dimensional modeling engineering surveying is used, when the drone flies too low and hits an obstacle, the power parts cannot be opened in time, the drone will fall to the ground and cause damage. Therefore, this patent designs a triangular seat and a protective airbag. The triangle has stability and can make the drone have a higher balance. At the same time, when the power parts cannot be opened in time, the protective airbag is opened to avoid the bottom of the drone falling to the ground and causing damage.

During the flight, when it is about to hit a wall or an obstacle, the drone body 1 is controlled to bend the articulated frame 7 downward through the connecting seat 6, and press the spring 11 and the telescopic rod 12. Since the telescopic rod 12 is hinged at both ends, when the articulated frame 7 is bent downward through the connecting seat 6, the spring 11 can be limited to prevent the spring 11 from elastic deformation. At the same time, the power piece 9 is closed, and the four articulated frames 7 are folded inward to shrink. At the same time, the inflatable airbag 3 is opened. When it hits an obstacle, the airbag is used for cushioning to avoid damage to the drone body 1.

[0021] In this embodiment, Figure 1 As shown, four smooth grooves 4 are opened on the side surface of the connecting frame 2, and the four smooth grooves 4 are distributed in a circular array.

During the flight, when it is about to hit a wall or an obstacle, the drone body 1 is controlled to bend the articulated frame 7 downward through the connecting seat 6, and the spring 11 and the telescopic rod 12 are pressed. Since the telescopic rod 12 is hinged at both ends, when the articulated frame 7 is bent downward through the connecting seat 6, the spring 11 can be limited to prevent the spring 11 from elastic deformation. At the same time, the power piece 9 is closed, and the four articulated frames 7 are folded inward. The airbag 3 is folded and shrunk, and the airbag 3 is opened at the same time. When the drone hits an obstacle, the airbag is used for cushioning to avoid damage to the drone body 1. When the drone flies too low and hits an obstacle, the power part 9 cannot be opened in time, and the drone will fall to the ground and cause damage. Therefore, the patent designs a triangular seat 15 and a protective airbag 16. The triangle has stability and can make the drone have a higher balance. At the same time, when the power part 9 cannot be opened in time, the protective airbag 16 is opened to avoid the bottom of the drone from falling to the ground and causing damage.
