Description

Technical Field

[0001] The utility model belongs to the technical field of unmanned aerial vehicles and relates to an unmanned aerial vehicle RTK module connecting device. Background Art

[0002] At present, domestic civilian-grade drones are only used by consumers in conventional fields such as image shooting, entertainment, and educational games. The image parameters of their lenses meet the requirements for real-scene modeling data collection. In certain usage scenarios, they can be matched with corresponding flight control software, graphics and data processing software to collect real-scene modeling data, which will expand the three-dimensional digital application scenarios of civilian-grade drones in engineering and surveying and mapping industries. However, most civilian-grade drones currently rely only on GPS signal positioning, and the accuracy is generally lower than the meter level, resulting in the accuracy of the collected data modeling failing to meet the implementation requirements of some projects.

[0003] RTK (Real-Time Kinematic) is a real-time dynamic positioning technology based on carrier phase observations. It can provide three-dimensional positioning results of the measuring station in real time in a specified coordinate system and achieve centimeter-level accuracy. For drones, RTK helps improve positioning accuracy and reduce flight errors.

[0004] Most existing drones have built-in RTK modules installed inside the drone. For drones that do not have RTK modules pre-installed at the factory, external modules are installed on the drone. Currently, the external modules are mostly connected to the drone through a clamp. The clamp is connected to the drone through a pin block and an axle pin in conjunction with a torsion spring. When the clamping end is forced outward, the pin block is likely to apply a squeezing force to the torsion spring, causing positional displacement, resulting in insufficient clamping force, which cannot perform rigid positioning work well and reduces the clamping stability.

[0009] Furthermore, a plurality of the snap holes are circumferentially arranged on the clamping end.

[0010] Furthermore, the cross-sectional shape of the limiting post is in the shape of "plus", and one end of the limiting post inserted into the snap hole is provided with a guiding surface to guide when the limiting post is inserted into the snap hole, facilitating the insertion of the limiting post into the snap hole.

[0011] Furthermore, the two clamp bodies are connected to the RTK module through connecting bolts.

[0012] Furthermore, the clamp body is made of stainless steel with a thickness of 0.25 mm, having high strength and corrosion resistance, and can be used repeatedly for a long period.
