Vehicle Lamp Module Sensor Rotation Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing auto leveling systems in vehicles adjust the headlamp direction but not the sensor directions, leading to degraded sensor sensitivity due to vehicle position changes, especially in the front-rear direction.
Innovation Solution
A vehicle lamp module with a beam pattern forming part, a sensor part, a driving part, and a connection part that allows the sensor and lamp directions to be automatically adjusted together with the vehicle position changes, using a rotatable connection mechanism to ensure synchronized movement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If only the headlamp direction is adjusted by the auto leveling system, then the headlamp illumination direction is maintained, but the sensor sensitivity degrades due to vehicle position changes
Solution Approach 1:
The patent combines the headlamp and sensor into a single integrated lamp module assembly. The connection part couples the sensor part to the beam pattern forming part, enabling them to move together as one unit when the vehicle position changes, thereby maintaining sensor sensitivity without requiring a separate adjustment mechanism
Solution Approach 2:
The auto leveling system is designed to simultaneously adjust both the headlamp direction and sensor direction through the same driving part and connection part mechanism. This multi-functional approach allows one system to serve multiple purposes: illuminating the road while maintaining sensor detection accuracy
2Adaptability or versatility
If the sensor part is rotated independently, then the sensor direction is adjusted, but the beam pattern forming part cannot be adjusted simultaneously
Solution Approach 1:
The connection part structurally couples the sensor part and beam pattern forming part together. When the driving part rotates the sensor part, the connection part transmits this motion to the beam pattern forming part, enabling synchronized rotation of both components through a single adjustment mechanism
Solution Approach 2:
The connection part is designed with rotational freedom, allowing it to dynamically adapt its orientation as the sensor part rotates. This dynamic coupling enables both the sensor and beam pattern to be adjusted simultaneously while maintaining their relative positional relationship
3Stability of the object's composition
If the connection part rigidly connects the beam pattern forming part and sensor part, then they move together, but the sensor rotation range is limited
Solution Approach 1:
The connection part employs a dynamic coupling mechanism that maintains stable relative positioning between the sensor and beam pattern while allowing rotational movement. The connection part can rotate along with the sensor, providing both stability and adaptability within the required rotation range

AI summary
A vehicle lamp module and a vehicle including the vehicle lamp module are provided. The vehicle lamp module includes a beam pattern forming part to form a beam pattern of light irradiated externally from a vehicle, a sensor part provided at one side of the beam pattern forming part to sense an external region including the beam pattern, a driving part coupled to one side of the sensor part to provide a driving force for rotating the sensor part to change the external region that the sensor part faces, and a connection part interposed between the beam pattern forming part and the sensor part to selectively connect or disconnect the beam pattern forming part and the sensor part with or from each other.
