Dual-Mode Vehicle Door Hinge for Side-Opening and Swing-Up Access
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle doors are limited to a single opening method, which restricts their use in various environments due to space constraints, and there is a need for a design that allows for multiple opening modes to enhance user convenience and aesthetic appeal.
Innovation Solution
A dual-mode vehicle door electric system featuring a hinge assembly with a connecting mechanism and driving mechanism, allowing for both side opening and swing-up opening operations, utilizing a locking mechanism with first and second locking parts and a rotating component to facilitate both modes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a conventional single-mode door opening mechanism is used, then the structure is simple, but the door opening is limited by environmental space constraints
Solution Approach 1:
The hinge assembly is designed to perform multiple functions: it can lock the door in a closed position, enable lateral opening movement, and enable swing-up opening movement. The first locking part locks the vehicle door member on the vehicle body member, while the second locking part locks the vehicle door connecting member on the vehicle door member, allowing the same hinge structure to support both opening modes
Solution Approach 2:
The hinge assembly is divided into distinct functional components: a bracket mechanism with vehicle body member and vehicle door member, a connecting mechanism with vehicle door connecting member, and a locking mechanism with first and second locking parts. This segmentation allows independent control of locking and opening functions for each mode
2Shape
If scissor doors are used to achieve upward-sweeping posture, then visual impact is enhanced, but longitudinal space is required
Solution Approach 1:
The system dynamically switches between two opening modes based on spatial requirements. The swing-up opening mode provides the desired upward-sweeping posture for visual impact, while the lateral opening mode provides an alternative when longitudinal or transverse space is constrained, allowing the door to adapt its movement trajectory
3Ease of operation
If side-opening doors are used, then transverse space is required, but the door opening is still limited by environment
Solution Approach 1:
The hinge assembly serves as a universal mechanism that can accommodate both side-opening and swing-up opening methods. The locking mechanism with two locking parts enables the system to switch between lateral opening (when transverse space is available) and swing-up opening (when longitudinal space is available), making the door operation adaptable to different environmental constraints

AI summary
The present disclosure relates to the field of vehicle doors, and in particular, to a dual-mode vehicle door electric system and a vehicle with the same. The electric system includes a hinge assembly, wherein the hinge assembly is connected with a connecting mechanism and a driving mechanism; the driving mechanism includes a side opening driving mechanism and a swing-up driving mechanism; the hinge assembly includes a bracket mechanism and a locking mechanism; the bracket mechanism includes a vehicle body member and a vehicle door member, the vehicle door member being rotatable on the vehicle body member; the connecting mechanism includes a vehicle door connecting member arranged on the vehicle door member, the vehicle door connecting member being rotatable on the vehicle door member under the push of the side opening driving mechanism; and the locking mechanism includes a first locking part and a second locking part that are connected to the vehicle door member for locking and limiting the vehicle door. In the present disclosure, through the cooperation of the hinge assembly, the connecting mechanism, and the driving mechanism, the vehicle door installed with the electric system can have two door opening methods, which facilitates the use of the vehicle door in the actual opening process.
