Unmanned aerial vehicle damping structure

Abstract

This utility model discloses a shock absorption structure for unmanned aerial vehicles (UAVs), relating to the field of UAV shock absorption. It includes an adapter PCB, with small shock-absorbing columns fixed to the UAV's flight control board on its inner wall. Four-legged silicone pillars are fixedly connected to the top of the adapter PCB, and IMU sensors are mounted on the tops of these pillars. A counterweight is located on one side of the four-legged silicone pillars at the top of the adapter PCB, used to increase the overall module's shock absorption. The four small shock-absorbing columns, the four-legged silicone pillars, the IMU sensors, and the counterweight are mounted on the adapter PCB, increasing its weight. The other ends of the four small shock-absorbing columns are fixed to the UAV's flight control board. When the UAV is operating, the four small shock-absorbing columns provide overall module shock absorption, effectively reducing the shock for the adapter PCB and the IMU sensors.

[0014] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions in the embodiments of this utility model are described clearly and completely. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0015] To better understand the above technical solutions, the following will provide a detailed explanation of the technical solutions in conjunction with the accompanying drawings and specific implementation methods.

[0016] This utility model discloses a shock absorption structure for a drone, according to the attached... Figure 1-3As shown, the system includes an adapter PCB1. The inner wall of the adapter PCB1 is provided with small shock-absorbing columns 2 that are fixed to the flight control board of the UAV. The top of the adapter PCB1 is fixedly connected to a four-legged silicone column 3. An IMU sensor 4 is installed on the top of the four-legged silicone column 3. A counterweight block 5 is provided on one side of the top of the adapter PCB1 located on the four-legged silicone column 3. The counterweight block 5 is used to increase the counterweight of the adapter PCB1 to achieve overall module shock absorption. The four sets of small shock-absorbing columns 2 are fixed at one end to the flight control board of the UAV and at the other end to the adapter PCB1. When the UAV is working, the four sets of small shock-absorbing columns 2 absorb the shock of the adapter PCB1. The outer wall of the adapter PCB1 has two sets of interconnected circuit through holes 6. The contact part between the small shock-absorbing column 2 and the adapter PCB1 has mounting holes 7, which facilitates the small shock-absorbing column 2 to be fixed on the adapter PCB1 through the mounting holes 7. When the adapter PCB1 is powered on, heat is dissipated through the circuit through holes 6.

[0017] According to the appendix Figure 1-3 As shown, further, four sets of small shock-absorbing columns 2 are provided. The positions of the four sets of small shock-absorbing columns 2 are symmetrically arranged about the adapter PCB1. By fixing the four sets of small shock-absorbing columns 2 to the flight control board of the UAV, the adapter PCB1 can be more stably installed on the flight control board of the UAV.

[0018] According to the appendix Figure 1-3 As shown, further, the end of the IMU sensor 4 furthest from the four silicone posts 3 is soldered to the top of the adapter PCB 1. When the IMU sensor 4 is powered on, the data measured by the IMU sensor 4 is transmitted to the adapter PCB 1.

[0019] According to the appendix Figure 1-3 As shown, further, the overall module refers to the adapter PCB1 and all the components on the adapter PCB1.

[0020] According to the appendix Figure 1-3 As shown, the adapter PCB1 further includes a cavity connected to two sets of circuit through holes 6. When the adapter PCB1 is powered on, it generates heat that is conducted into the air. Through the two sets of circuit through holes 6, the air inside the adapter PCB1 can interact with the air outside the adapter PCB1, thus dissipating heat from the adapter PCB1.

[0021] Working principle: Four sets of small shock-absorbing columns 2, four-legged silicone columns 3, IMU sensor 4 and counterweight block 5 are installed on the adapter PCB1. The counterweight block 5 increases the weight of the adapter PCB1. The other end of the four sets of small shock-absorbing columns 2 is fixed to the flight control board of the drone. When the drone is working, the four sets of small shock-absorbing columns 2 achieve overall module shock absorption, thereby reducing the shock of the adapter PCB1 and IMU sensor 4.
