AI Technical Summary
The heat dissipation of existing vehicle camera lens barrels is inadequate, which prevents the chip heat from dissipating quickly, potentially causing the camera to lag or be damaged.
Design a lens barrel with an embedded heat dissipation channel, which generates airflow through a ring fan and drive assembly to quickly dissipate heat. The lens barrel includes an inner cylinder, an outer cylinder, a heat dissipation channel, a ring fan, and a drive assembly. A motor drives a gear and a gear ring to rotate the fan, forming an airflow from back to front.
This improves the cooling and heat dissipation of the vehicle-mounted camera, preventing operational lag or damage caused by chip overheating.
