Description

Technical Field

[0001] This utility model relates to the field of unmanned aerial vehicle (UAV) technology, and in particular to a shock-absorbing bracket for the throttle servo of a UAV. Background Technology

[0002] Unmanned aerial vehicles (UAVs) are aircraft controlled via radio remote control equipment and onboard program control devices. Their core equipment includes an autopilot, program control device, and information acquisition device. Operators can track, locate, control, and transmit data to the UAV through remote control equipment on a ground station or mother aircraft. UAVs are widely used in fields such as power line inspection, disaster emergency inspection, and agricultural and forestry plant protection. For gasoline-powered unmanned helicopters, the throttle control system is a key component ensuring flight stability and performance. This system connects the engine to the servo motor via a throttle cable, using the servo motor's rotation angle to adjust the throttle opening, thereby precisely controlling the engine's output power.

[0003] In current UAV throttle control systems, engine vibration has a significant impact on the servo motors, and traditional bracket designs are no longer sufficient to meet the requirements of high-performance UAVs. Therefore, designing a throttle servo vibration damping bracket with excellent shock absorption performance has become an urgent technical challenge. Utility Model Content

[0007] Further technical solutions also include: a shock absorption module, which is located at the bottom of the support arm, at the upper and lower ends of the first screw hole and the second screw hole, respectively.

[0011] A further technical solution involves using screws as the connecting device.

[0012] A further technical solution involves multiple sets of shock-absorbing modules, placed at the top and bottom ends of the support arm.
