Rotating Sliding Door Arm Structure for Wider Vehicle Openings
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional sliding-type compartment opening/closing doors for vehicles face challenges such as excessive space intrusion by the door arm into the vehicle's side sill and limited door open amount due to a fixed sliding door arm structure.
Innovation Solution
A sliding door structure that combines linear motion and rotational motion by coupling a rotatable door arm to a slider moving along a linear rail, allowing the door arm to be rotated and fixed as the slider moves, thus minimizing space intrusion and maximizing door opening width.

1Ease of operation
If a fixed sliding door arm structure is used, then the door can be opened and closed, but the door arm intrudes excessively into the side sill part requiring increased floor height
Solution Approach 1:
The door arm is transformed from a fixed structure to a dynamic structure that can rotate and slide. The rotation unit enables the door arm to change its orientation angle, while the sliding unit allows the door arm to adjust its position along the sliding direction, thereby reducing space intrusion into the side sill area.
Solution Approach 2:
The door arm movement is extended from one-dimensional sliding to two-dimensional motion by adding rotational capability. The door arm can now move along the sliding direction and also rotate around the rotation axis, providing additional spatial freedom to minimize intrusion into the side sill space.
2Ease of operation
If a fixed sliding door arm structure is used, then the door can be opened and closed, but the door open amount is limited and door protrusion amount is excessive
Solution Approach 1:
The door arm structure is made dynamic through the rotation unit that changes the orientation angle of the door arm. This rotational freedom allows the door to achieve greater opening amounts by adjusting the door arm's angle relative to the vehicle body, rather than being constrained to a fixed geometric configuration.
Solution Approach 2:
The orientation angle of the door arm is changed as a variable parameter through the rotation unit. By adjusting this angle, the door open amount can be optimized to maximize the opening width while minimizing the protrusion amount, providing flexible control over the door's spatial configuration.

AI summary
A sliding door structure for a vehicle includes a door configured to open and close an opening of a vehicle body, a door arm that connects the door to the vehicle body, a slider connected to an end of the door arm and slide-moved along a linear rail installed on the vehicle body, a hook disposed on the slider and rotated by the movement of the slider to rotate the door arm, a rotation pin disposed on the linear rail and rotating the hook by being coupled to or uncoupled from the hook when the slider is moved, a release button disposed on the slider and rotated in contact with the rotation pin when the slider is moved, and a gear lock in contact with the release button and rotated by the rotation of the release button to fix or release the rotation of the door arm.
