Sliding Door Limiting Mechanism With Locking Opening Angle
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing limiting structures in electrical cabinets fail to securely lock the position of the door, leading to unwanted movement due to external forces, which interferes with worker operations.
Innovation Solution
A limiting mechanism featuring a connecting seat with a guide structure and a connecting shaft that slides along the guide structure, locked by a locking position, ensuring the door's opening degree is stable and preventing unwanted movement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a limiting structure is used to control the opening range of the door, then the door opening degree is limited, but the limiting structure cannot lock the position of the door, causing the door to move due to external forces
Solution Approach 1:
The connecting shaft is designed to be movable within the guide structure, allowing it to slide along the guide structure as the door opens and closes. This dynamic adjustment enables the limiting mechanism to adapt to different door opening angles while maintaining stable positioning through the locking position feature
Solution Approach 2:
The connecting shaft acts as an intermediary element between the door and the limiting structure. It transmits the door's movement to the guide structure while being constrained by the locking position, thereby mediating between the need for door movement and the need for position stability
2Ease of operation
If the door is hinged to the case for easy opening and closing, then the door is easy to operate, but the hinged portion is prone to deformation due to door movement
Solution Approach 1:
The limiting mechanism with locking position is installed beforehand to preemptively prevent excessive door opening. By establishing the maximum opening angle limit in advance, the hinged portion is protected from deformation before it can occur during normal door operation

AI summary
A limiting mechanism and an energy storage device. The limiting mechanism comprises: a connecting seat provided with a guide structure. The guide structure is arranged in the length direction of the connecting seat; a connecting shaft in sliding fit with the guide structure; and a connecting arm connected to the connecting shaft. A locking position for locking the position of the connecting shaft in the length direction of the connecting seat is further provided on the connecting seat. When the connecting arm and the connecting seat are unfolded, the connecting shaft can slide along the guide structure to adapt to the unfolding angle between the connecting arm and the connecting seat, and when the connecting shaft slides to the locking position, the locking position can lock the position of the connecting shaft, and the unfolding angle between the connecting arm and the connecting seat is locked.
