Automatic Locking Structure for UAV Arm Assembly
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing unmanned aerial vehicles (UAVs) face stability issues due to the need for manual locking of arms, which can lead to safety hazards if not securely locked, increasing the risk of crashes when operators forget to lock the arms properly.
Innovation Solution
A locking structure that automatically locks the arm in the unfolded state when it reaches a preset angle, eliminating the need for manual operation and ensuring the arm remains securely locked without additional user intervention.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If manual locking operation is required after arm unfolding, then the arm can be locked in position, but the operator may forget to lock the arm securely, causing safety hazards and potential crashes
Solution Approach 1:
The locking assembly is designed to automatically lock the arm in the unfolded state without requiring manual operation. The movable member rotates to unfold the arm, and the locking assembly automatically engages to secure the arm in position, making the system self-servicing and eliminating the need for operator intervention.
Solution Approach 2:
The locking assembly performs the locking action in advance as part of the unfolding process itself. When the movable member rotates to the unfolded position, the locking assembly automatically engages before the arm is fully deployed, ensuring the arm is secured during the unfolding operation without requiring a separate manual locking step.
2Ease of operation
If the locking assembly automatically locks when preset angle is reached, then manual operation is eliminated and safety is improved, but the device complexity increases
Solution Approach 1:
The locking function is merged with the unfolding motion of the movable member. The locking assembly is integrated into the movable member structure, and the locking action occurs automatically as part of the rotation process, combining two functions (unfolding and locking) into a single integrated mechanism.
Solution Approach 2:
The locking assembly acts as an intermediary mechanism between the movable member's rotation and the arm's final positioned state. It translates the rotational motion into automatic engagement, mediating the transition from unfolded to locked state without requiring direct manual intervention.

AI summary
The present disclosure provides a locking structure, an arm assembly and a movable platform. The locking structure includes a mounting member, a movable part member and a locking assembly. The movable part member is rotatably connected to the mounting member. The locking assembly is disposed on the mounting member or the movable member. When the mounting member and the movable member are rotated to form a preset angle, the locking assembly may synchronously lock the mounting member and the movable member in the current position, so that the movable member is kept in an unfolded state.
