Vehicle Sliding Door Rail and Telescopic Linkage for Wider Opening
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Sliding vehicle doors are prone to accumulate foreign matter in their sliding rails, limiting their use to rear doors only due to vehicle shape constraints and restricting the opening degree of the door.
Innovation Solution
A door apparatus with a sliding rail mechanism and a transmission mechanism, including a mechanical or hydraulic telescopic arm, allows the door to slide laterally and open outward, hidden within the vehicle body, enabling use in both front and rear doors without shape limitations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a sliding rail mechanism is exposed on the vehicle body for sliding door operation, then the door can slide smoothly, but foreign matter accumulates in the sliding rail
Solution Approach 1:
The sliding rail mechanism is extracted from the external vehicle body surface and relocated to the internal door cavity. The sliding rail remains functional for door operation but is hidden inside the door structure, preventing foreign matter accumulation while maintaining smooth door sliding capability
Solution Approach 2:
The sliding rail mechanism is nested within the door body cavity. The sliding portion moves along the sliding rail that is internally mounted in the door structure, allowing the door to slide while the rail remains protected inside the door rather than exposed externally
2Adaptability or versatility
If a sliding vehicle door structure is used, then the door can be installed in rear door positions, but the vehicle shape is constrained and opening degree is limited
Solution Approach 1:
The door apparatus employs a dynamic transmission mechanism with telescopic arms that can extend and retract. This dynamic structure allows the door to achieve various opening degrees and positions, adapting to different vehicle shapes and door locations (front or rear doors) without being constrained by fixed geometric limitations
Solution Approach 2:
The transmission mechanism introduces additional motion dimensions through the telescopic arms that can both rotate and extend/retract. This multi-dimensional motion capability enables the door to overcome the traditional single-plane sliding limitation and adapt to various vehicle configurations and opening requirements
3Shape
If the door body and side panel are in the same plane when closed, then the vehicle appearance is streamlined, but the opening degree is restricted
Solution Approach 1:
The telescopic transmission arms provide dynamic motion capability, allowing the door to transition from a closed position (aligned with side panel) to various opening positions. The arms can extend to provide greater opening degree while retracting to maintain streamlined appearance when closed
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 prevents foreign matter accumulation, increases the lateral opening degree, reduces outward opening space, and enhances the convenience and comfort of using sliding doors in various vehicle configurations.
Implementation Method 1
the transmission mechanism may alternatively be a hydraulic telescopic arm. When the hydraulic telescopic arm is compressed, the door body can be driven to move toward an inner side of the vehicle body
Implementation Method 2
the transmission mechanism may be a mechanical swing arm including a transmission apparatus, and the mechanical swing arm is bent and unfolded based on the transmission apparatus

AI summary
A connection apparatus is disclosed, including: a sliding rail mechanism, where the sliding rail mechanism includes an internal rack; and a transmission mechanism, where the transmission mechanism includes a sliding portion, and the sliding portion is engaged with the internal rack. The sliding rail mechanism is configured to move relative to the sliding portion under driving of the sliding portion. A door apparatus including the connection apparatus and a vehicle are further provided. The door apparatus including the connection apparatus is used in the vehicle, so that use of a sliding door is no longer limited by a vehicle shape. In addition, this helps increase an opening degree of lateral sliding of a door body and effectively limits an opening degree of longitudinal pushing and pulling of the door body.
