Handheld Gimbal Clamping Lock for Stable Camera Angle
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional handheld gimbals fail to prevent mobile phone rotation when powered off or out of power, leading to unstable camera angles and user experience issues.
Innovation Solution
A clamping mechanism with a locking component, comprising a locking ring and ring seat with external and internal threads, and a gimbal motor for adjustable clamping, which locks the angle between the clamping arm and connecting arm, preventing relative rotation and ensuring stable camera positioning.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a conventional handheld gimbal is used without a locking component, then the device can rotate freely for adjustment, but the mobile phone rotates or shakes when the gimbal powers off, causing screen orientation changes
Solution Approach 1:
The locking component is activated after the clamping arm reaches the desired position to lock the connecting arm, preventing unintended rotation when powered off. This preliminary locking action ensures the camera angle remains stable without requiring continuous power supply.
Solution Approach 2:
The locking component acts as an intermediary mechanism between the clamping arm and connecting arm, physically preventing relative rotation through mechanical engagement of the locking ring and ring seat with thread structures.
2Reliability
If a locking component is added to prevent rotation when powered off, then camera angle stability improves, but the device structure becomes more complex
Solution Approach 1:
The locking component integrates multiple functions: the locking ring and ring seat with thread structures provide both the locking mechanism and the drive interface for the driving component, while also serving as structural connection elements between the clamping arm and connecting arm.
Solution Approach 2:
The locking component is integrated with the existing clamping arm and connecting arm structures. The ring seat is disposed on the clamping arm and the locking ring engages with it, merging the locking function into the existing mechanical framework rather than adding completely separate components.
3Ease of operation
If a thread-based locking mechanism is used, then the locking component can be easily engaged and disengaged, but manufacturing precision requirements increase due to threading
Solution Approach 1:
The thread structures on the locking ring and ring seat automatically engage and lock the components in place when the locking component is rotated, without requiring additional fastening steps or tools. The self-locking thread mechanism provides both easy operation and reliable engagement.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The solution effectively locks the angle between the clamping arm and connecting arm, preventing mobile phone rotation after adjusting the shooting angle, thereby enhancing the user experience of handheld gimbals by maintaining stable camera stability even when powered off.
Implementation Method 1
An external thread is disposed on the ring seat. An internal thread is disposed on the locking ring and matches with the external thread. The locking ring is moved toward the clamping arm by matching the internal thread with the external thread when the locking ring rotates.
Implementation Method 2
a knurl is disposed on a periphery surface of the locking ring to increase friction
Implementation Method 3
the gimbal motor comprises a permanent magnet pole, a winding coil and a rotating shaft. The winding coil is disposed on the sleeve and is located inside the permanent magnet pole.

AI summary
The present disclosure relates to a field of shooting support device, and to a champing mechanism and a handheld gimbal. The clamping mechanism includes an upper clamping portion, a lower clamping portion opposite to the upper clamping portion, a clamping arm connected to the upper clamping portion and the lower clamping portion, a connecting arm rotably connected with the clamping arm, and a locking component. The locking component limits relative rotation of the clamping arm and the connecting arm. The locking component is disposed on a rotational connection position of the clamping arm and the connecting arm.
