Vehicle Camera Shielding Mechanism for Panoramic Imaging Clearance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle-mounted camera devices face issues with contamination and damage due to exposure, and existing shielding mechanisms either obstruct panoramic imaging or risk damaging the camera components during movement.
Innovation Solution
A shielding device with a shielding member that pivots and rotates, allowing it to move away from and towards the camera without obstructing 360° imaging, and fits securely against the camera cover without causing damage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a movable shield plate is used to protect the camera, then the camera is protected from contamination and damage, but the shield plate may obstruct panoramic imaging when not properly positioned
Solution Approach 1:
The shielding member is designed to be movable between a closed position (providing protection) and an open position (clearing the imaging path). The dynamic positioning mechanism allows the shield to adapt its position based on operational requirements, resolving the contradiction between protection and imaging clarity.
2Reliability
If the shield plate translates or rotates to move between positions, then the shielding function is achieved, but the movement mechanism may risk damaging camera components
Solution Approach 1:
A guide structure acts as an intermediary between the movable shield plate and the camera components. This guide structure constrains the shield's movement path, ensuring it moves smoothly between positions without colliding with or damaging the camera components, thus enabling the shielding function while eliminating the damage risk.
3Reliability
If the shield plate covers the camera when not in operation, then contamination and damage are prevented, but the camera cannot be exposed for operation
Solution Approach 1:
The shield plate is designed with dynamic positioning capability, allowing it to automatically or manually transition between a closed protective position and an open operational position. This dynamic design ensures the camera is fully covered during non-operation for protection, yet easily exposed during operation without mechanical complexity.

AI summary
A shielding device for a vehicle-mounted camera device having a camera. The shielding device includes a shielding member, a first motion actuating element, a second motion actuating element and a driving device. The shielding member has a closed position and an open position. The first motion actuating element and the shielding member are pivotably connected about a first axis. The first motion actuating element is rotatably mounted about a second axis and configured to drive the shielding member to rotate about the second axis relative to the camera. The second motion actuating element and the shielding member are pivotably connected at a distance from the first axis. The second motion actuating element drives the shielding member to flip relative to the camera about the first axis. The driving device is drivingly connected with the first motion actuating element and the second motion actuating element and configured to drive the first motion actuating element and the second motion. The shielding member is driven to rotate about the second axis and is concurrently driven to flip about the first axis, so as to move between the closed position and the open position.
