Description

Technical Field

[0001] The utility model relates to the technical field of cameras, and particularly relates to a DMS module. Background Art

[0002] The occurrence of traffic accidents is affected by various factors, including driving behavior, road conditions, vehicle status, etc.

[0003] In order to reduce the occurrence of traffic accidents, dual-channel IPC cameras have emerged. The dual-channel IPC cameras have both driver behavior monitoring DMS cameras and ADAS assisted driving functions, which can effectively improve driving safety and have positive social and economic effects.

[0004] The existing DMS and ADAS of dual-channel IPC cameras can be divided into independent functional modules or a dual-channel integrated structure. However, this internal structure is complex, with low integration. Moreover, the fill light and internal components in the DMS functional module will generate heat during operation, causing the internal components of the DMS functional module to work in a high-temperature environment, affecting performance, lifespan, and reliability. Additionally, the current DMS functional module does not have a structure for positioning the lens, prone to lens assembly deviation, reducing the overall visual effect of the DMS functional module. And the DMS functional module is usually fixed by screws or snap positions, which is not convenient for assembly. Summary of the Utility Model

[0005] Aiming at the problems of inconvenient assembly, inaccurate lens positioning, and too high internal temperature in the existing DMS functional module, the utility model proposes a DMS module to solve the above technical problems.

[0006] According to the first aspect of the present application, a DMS module is proposed, which includes a lens, a DMS front shell, a fill light, a DMS lens module, and a DMS rear shell. Fixed columns are provided inside the DMS rear shell, and fixing holes adapted to the fixed columns are provided inside the DMS front shell.

Lens openings for passing through the lens are provided at the centers of both the fill light and the DMS front shell. The lens passes through the lens openings of the fill light and the DMS front shell to the lower side of the lens.

[0020] In some specific embodiments, lamp beads are provided on both sides of the lens opening of the fill light.

[0021] By adopting the above technical solutions, the lens can pass through the center of the fill light to the lower side of the lens, and the lamp beads of the fill light can be arranged on both sides slightly lower than the lens, ensuring sufficient light when the lens takes pictures.

[0022] In some specific embodiments, the fill light is provided with a power supply line for supplying power to the lamp beads, and the DMS lens module is provided with a wire hole through which the power supply line passes.
