Description

Technical Field

[0001] The utility model relates to the technical field of unmanned aerial vehicle surveying and mapping, and in particular to a bracket device used for unmanned aerial vehicle surveying and mapping. Background Art

[0002] Unmanned aerial vehicles (UAVs) are unmanned aircraft that are controlled by radio remote control equipment and self-contained program control devices, or are fully or intermittently autonomously operated by onboard computers. UAVs can be used in a variety of industries when paired with surveying instruments.

[0003] For example, a Chinese patent with publication number CN218806515U discloses a shock-absorbing bracket for unmanned aerial vehicle surveying and mapping. In view of the fact that the existing unmanned aerial vehicle brackets are prone to collision with the ground and vibration, which will reduce the service life of the unmanned aerial vehicle, and the surveying and mapping equipment is mostly arranged inside the unmanned aerial vehicle, it is relatively cumbersome to disassemble and repair it, and it is not convenient to install it after disassembly, which reduces the work efficiency. Now, the following scheme is proposed, which includes an unmanned aerial vehicle body; two unmanned aerial vehicle brackets, the two unmanned aerial vehicle brackets are arranged on the lower side of the unmanned aerial vehicle body for landing; two sets of shock-absorbing mechanisms, the two sets of shock-absorbing mechanisms are respectively arranged between the two unmanned aerial vehicle brackets and the unmanned aerial vehicle body to reduce the vibration of the unmanned aerial vehicle body; the surveying and mapping device can effectively prevent the vibration of the unmanned aerial vehicle when it lands from being transmitted to the unmanned aerial vehicle body, and can ensure the service life of the electronic components inside the unmanned aerial vehicle;

[0004] The technical solution recorded in this proposal sets up two sets of shock-absorbing mechanisms to prevent the vibration generated when the drone lands from being transmitted to the drone body, thereby ensuring the service life of the drone's internal electronic components. However, the height of the shock-absorbing mechanism in this proposal cannot be adjusted. When landing on complex terrain, when the weeds on the ground are deep, after the drone lands, the blades are easily entangled with the weeds, thereby affecting the subsequent flight of the drone.

[0005] Therefore, in view of this, the existing structure and deficiencies are studied and improved, and a bracket device for drone mapping is provided, in order to achieve a purpose with greater practical value. Utility Model Content

[0038] Embodiment 3 of the support device for unmanned aerial vehicle surveying and mapping of the utility model

[0039] Reference Figure 1-Figure 5As shown, a transmission box 2006 is fixedly installed on the upper end of each pair of first adjustment frames 2002 and second adjustment frames 2009, a power box 2007 is fixedly installed between one end of a pair of transmission boxes 2006, and a first servo motor 2008 is fixedly installed on one side of the power box 2007. By installing the transmission box 2006, it is convenient to transmit the first adjustment frame 2002 and the second adjustment frame 2009. By installing the power box 2007, it is convenient to drive the internal mechanism of the transmission box 2006 to operate. The interior of the transmission box 2006 is rotatably connected to the first rotating shaft 2021, and the first bevel gear 2015 is sleeved on both ends of the first rotating shaft 2021. A pair of retaining frames 2008 are fixedly installed inside the power box 2007. 018, a second rotating shaft 2016 is rotatably connected between a pair of retainers 2018, and second bevel gears 2017 are sleeved at both ends of the second rotating shaft 2016. By sleeved first bevel gears 2015 at both ends of the first rotating shaft 2021, a pair of first bevel gears 2015 can be made to rotate synchronously, and by sleeved second bevel gears 2017 at both ends of the second rotating shaft 2016, the second bevel gears 2017 can be made to rotate synchronously.

The bevel gear plates 2014 are meshed with the first bevel gears 2015 and the second bevel gears 2017. A bevel gear 2014 is sleeved on the top of the second screw 2011, and is meshed with the first bevel gear 2015 and the second bevel gear 2017. When the second rotating shaft 2016 rotates, the meshing between the first bevel gear 2015 and the second bevel gear 2017 and the bevel gear 2014 can be utilized to make the first screw 2010 and the second screw 2011 rotate synchronously, thereby controlling the first telescopic frame 2005 and the second telescopic frame 2022 to rise and fall synchronously. A worm gear 2019 is sleeved at the center of the second rotating shaft 2016. A worm 2020 is rotatably connected to the bottom end of the worm gear 2019 inside the power box 2007. The worm 2020 and the worm gear 2019 are meshed with each other. The first servo motor 2008 The output end is connected by transmission with the worm 2020.

During landing, the landing gear 2004 first contacts the ground, thereby causing the first shock absorbing seat 2003 and the second shock absorbing seat 2023 to extend and retract at the bottom ends of the first telescopic frame 2005 and the second telescopic frame 2022, respectively, thereby squeezing the spring 2012 and the shock absorber 2013. Under the coordination of the damping effect of the shock absorber 2013 and the elastic effect of the spring 2012, a shock absorbing effect is achieved, thereby preventing the landing from causing damage to the internal electronic components of the drone body 1001.

[0041] It should be noted that in a bracket device used for drone mapping, the specific models and specifications of the first servo motor 2008, the second servo motor 1003 and the drone body 1001 need to be selected and determined based on the actual specifications of the device, and the specific selection calculation method adopts the existing technology in the field, so it will not be described in detail.
