Twin Swing Gate Sealing Assembly With Rotating Center Bar
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Twin swing gates on vehicles face interference issues during opening and closing, leading to improper sealing and water intrusion, requiring a predetermined order of operation to maintain sealing between the gates.
Innovation Solution
A sealing assembly featuring a center bar unit that rotates in conjunction with the first gate, contacting the second gate when closed and spacing away when open, equipped with weatherstrips for sealing and a hinge mechanism for flexible operation, allowing both gates to open and close regardless of order while preventing water and noise intrusion.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a weatherstrip is mounted on one gate to provide sealing, then sealing between gates is improved, but the weatherstrip interferes with gate operation during opening and closing
Solution Approach 1:
The patent applies the dynamics principle by making the center bar movable rather than fixed. The center bar rotates about a hinge axis and can translate along the gate, allowing it to dynamically adjust its position. When the gate is closed, the center bar extends to contact the other gate for sealing. When the gate opens, the center bar retracts and rotates away, eliminating interference with the weatherstrip and enabling smooth operation.
2Object-affected harmful factors
If gates are tightly engaged to prevent water and noise intrusion, then sealing performance is improved, but the gates require predetermined opening and closing order
Solution Approach 1:
The patent applies preliminary action by positioning the center bar in advance on the first gate, equipped with sealing weatherstrips. The center bar is pre-configured to automatically contact the second gate when the first gate is closed, ensuring sealing is established before any potential water or noise intrusion can occur. This preliminary positioning eliminates the need for predetermined gate operation sequences.

AI summary
An embodiment is a sealing assembly for a twin swing gate of a vehicle, the sealing assembly including a first gate of which an outside end portion is hinge-connected to a vehicle, a second gate of which an outside end portion is hinge-connected to the vehicle and configured to be rotated in a direction opposite to rotation of the first gate, and a center bar unit along a height direction of the vehicle on an inside end portion of the first gate, the center bar being configured to rotate in conjunction with opening or closing the first gate.
