Description

Technical Field

[0001] The utility model relates to the technical field of connecting mechanisms for surveying and mapping instruments used in unmanned aerial vehicles, and specifically relates to a connecting mechanism for surveying and mapping instruments used in unmanned aerial vehicle surveying and mapping. Background Technique

[0002] An unmanned aerial vehicle generally refers to a remotely controlled flying device. During the surveying and mapping process, it is often necessary to connect a surveying and mapping device to the unmanned aerial vehicle to conduct topographic surveying work in the sky. When connecting the surveying and mapping device to the unmanned aerial vehicle, a connecting mechanism is often required to fix the surveying and mapping device at the bottom of the unmanned aerial vehicle. However, the existing connecting mechanisms for surveying and mapping instruments used in unmanned aerial vehicles have some deficiencies, such as:

[0003] For a surveying and mapping instrument fixing mechanism of a surveying and mapping unmanned aerial vehicle with the application number CN202320340579.0, this device uses a rotating device to drive the horizontal rotation of the first connecting plate. The top end of the connecting piece is connected to the bottom end of the first connecting plate. The middle part of the fixing plate is rotatably installed on the inner side wall of the connecting piece. The fixed end of the electric cylinder is rotatably installed at the bottom end of the first connecting plate through a hinge. However, in the actual use process, due to the different weights of the surveying and mapping devices, it may be necessary to conduct an unmanned aerial vehicle balance test first when connecting and fixing the surveying and mapping devices, thereby reducing the convenience of this device during installation.

[0004] Therefore, we propose a connecting mechanism for surveying and mapping instruments used in unmanned aerial vehicles to solve the problems raised above. Content of the Utility Model

[0005] The purpose of the utility model is to provide a connecting mechanism for surveying and mapping instruments used in unmanned aerial vehicles to solve the problems in the current market proposed in the above background technique.

A driving motor is connected inside the unmanned aerial vehicle body, and a first sprocket is connected to the front end of the driving motor. A chain is meshed outside the first sprocket, and a second sprocket is meshed with the left end of the chain. Lead screws are provided at the front ends of both the first sprocket and the second sprocket. A sliding plate is meshed outside the lead screw, and the sliding plate and the lead screw form a threaded sliding connection.

[0007] The bottom of the sliding plate is connected with a fixed shell, and a limiting mechanism is arranged inside the fixed shell. A fixed block is provided at the bottom of the fixed shell. The top of the fixed block fits with the inside of the fixed shell, and the fixed shell is snap-connected to the fixed block through the limiting mechanism. The bottom of the fixed block is connected with a connecting plate, and a connecting shell is provided at the bottom of the connecting plate. The inside of the connecting shell is connected to the detection equipment body.

[0008] By installing the detection device body in the connection plate, and then fixing it with the fixed shell through the fixing block set on the top of the connection plate to complete the connection work. When the drone drives the detection device body at the bottom, it may be difficult to balance. As a result, the driving motor drives the first sprocket and the second sprocket to rotate, causing the lead screw to drive the sliding plate to move, thereby adjusting the position of the detection device main body, increasing the convenience and stability of the device during installation and connection.

[0009] As a preferred technical solution of the present utility model, a rotary blade bracket is provided on the top of the drone body, and the drone body is connected to the rotary fan blades through the rotary blade bracket.

[0014] Adopting the above technical solution can set a clamping block inside the fixed shell, and the clamping block is pushed by the spring shaft. When the fixing block enters the fixed shell, the outside of the fixing block can be fixed by the clamping block, thereby increasing the stability of the fixed shell when connected to the fixing block. At this time, only a set of bolts is needed to connect the connection plate and the fixed shell, and the fixing block and the detection device body can be effectively limited and fixed in the horizontal and vertical directions.

At this time, when the UAV drives the detection device body at the bottom, it may be difficult to balance. As a result, the driving motor drives the first sprocket and the second sprocket to rotate, causing the lead screw to drive the sliding plate to move, thereby adjusting the position of the detection device main body, increasing the convenience and stability of the device during installation and connection;

[0022] By providing a clamping block inside the fixed shell, and the clamping block is pushed through a spring shaft, it can make the outside of the fixed block be fixed by the clamping block when the fixed block enters the fixed shell, thereby increasing the stability of the connection between the fixed shell and the fixed block.

Moreover, a fixed block 10 is provided at the bottom of the fixed shell 9. The top of the fixed block 10 fits inside the fixed shell 9, and the fixed shell 9 is snap-connected to the fixed block 10 through the limiting mechanism. Additionally, the bottom of the fixed block 10 is connected to a connection plate 15, and a connection shell 17 is provided at the bottom of the connection plate 15. The inside of the connection shell 17 is connected to the detection device body 16;

[0037] When using the instrument connection mechanism for UAV mapping, first install the detection device body 16 on the bracket of the connection plate 15 and the connection shell 17. Subsequently, insert the fixed block 10 into the inside of the fixed shell 9, and limit the fixed block 10 through the limiting mechanism provided inside the fixed shell 9, so that the fixed shell 9 and the fixed block 10 are fixedly connected. At this time, start the UAV body 1, so that the UAV body 1 flies at low altitude or high altitude, and observe the balance condition of the UAV body 1. When the UAV body 1 is in an unbalanced state, the driving motor 3 can drive the first sprocket 4, so that the first sprocket 4 drives the chain 5 and the second sprocket 6 to rotate, thereby making the lead screw 7 provided at the front ends of the first sprocket 4 and the second sprocket 6 rotate, and then making the lead screw 7 drive the sliding plate 8 to move, so that the sliding plate 8 drives the fixed shell 9 and the detection device body 16 provided at its bottom to perform position adjustment, so that the UAV body 1 is in a horizontal state;

[0045] When the fixed housing 9 is connected to the fixed block 10 through the limiting mechanism, the clamping block 14 will then retract under the drive of the spring shaft 12. When the clamping block 14 is located outside the clamping hole 11, the spring shaft 12 will drive the clamping block 14 to extend, so that the spring shaft 12 will push the clamping block 14 into the clamping hole 11, thereby limiting and fixing the fixed housing 9 and the fixed block 10.
