Handheld Gimbal Clamping Lock for Phone Orientation Stability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current handheld gimbals experience mobile phone rotation issues when powered off or out of power, causing screen orientation changes between vertical and horizontal modes.
Innovation Solution
A clamping mechanism with an upper and lower clamping portion, a clamping arm, a connecting arm, and a locking component that includes a locking ring and ring seat with external and internal threads, along with a gimbal motor comprising a permanent magnet, winding coil, and rotating shaft, to lock the angle between the clamping and connecting arms, preventing mobile phone rotation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If a handheld gimbal uses a mechanical balance adjustment system with clamping arms, then the balance and accuracy of the device are improved, but the mobile phone may still rotate or shake when the gimbal is powered off due to insufficient locking capability
Solution Approach 1:
The locking component is activated before the gimbal is turned off to pre-lock the clamping arm and connecting arm in their adjusted positions. This preliminary locking action ensures that when power is removed and the motor can no longer maintain position, the mechanical locking component has already secured the arms, preventing any subsequent rotation or shaking of the mobile phone.
Solution Approach 2:
The locking component acts as an intermediary mechanical element between the clamping arm and connecting arm. It provides a passive mechanical locking interface that does not require power, serving as a mediator to transfer and maintain the positional relationship between the arms even when the active motor system is deactivated.
2Device complexity
If the gimbal relies solely on motor power to maintain clamping arm position, then the structure can remain simple, but the phone orientation becomes unstable when power is lost
Solution Approach 1:
The locking function is extracted as a separate, independent component from the motor-driven clamping system. The locking component operates independently of the motor, providing a dedicated mechanical locking mechanism that can be engaged or disengaged as needed, rather than relying solely on the motor's continuous operation to maintain position.
Solution Approach 2:
The clamping system is segmented into two distinct functional parts: the motor-driven clamping arm for active positioning and adjustment, and the passive locking component for maintaining position. This segmentation allows each part to specialize in its function, with the locking component providing reliability without power while the motor provides active control when powered.
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 locking mechanism effectively stabilizes the mobile phone's orientation, enhancing the user experience by preventing unwanted rotation after adjusting the shooting angle, even when the gimbal is 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 permanent magnet pole is fixedly disposed on the connecting arm and is coaxial with the 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 clamping 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 aim 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 armor and the connecting arm.
