Driver fatigue driving early warning device

Abstract

The invention discloses a driver fatigue driving early warning device comprising an installing support and an upper cover and a lower cover which are assembled to form an early warning shell. The early warning shell is internally provided with a mainboard module, a light guide cover which is used for clamping the mainboard module and an alerter which is installed on the internal side of the uppercover. The infrared circuit board and the processor circuit board of the mainboard module are vertically connected through a connector, and the photographing circuit board and the infrared circuit board are installed in parallel through a connecting member so that arrangement is reasonable, the structure of the mainboard module is enabled to be compact, the overall dimension of the early warning device can be greatly reduced and the influence of excessively large dimension of the early warning device on driving of the driver can be avoided; and the internal wall of the lower cover of the earlywarning shell is provided with buckles used for clamping the mainboard module so that the mainboard module can be rapidly clamped, installation is rapid, disassembling is convenient and the installing and disassembling efficiency of the early warning device can be enhanced.

Description

technical field [0001] The invention relates to the technical field of automobile driving, in particular to a driver fatigue driving early warning device. Background technique [0002] With the gradual increase in the use of automobiles, various problems affecting traffic safety often occur in driving automobiles, among which fatigue driving is particularly common in driving. Fatigue driving reduces the sensitivity of the driver's five sense organs, slow thinking and judgment, and slow operation response, which can easily cause traffic accidents. According to statistics, fatigue driving accounts for more than 30% of all kinds of traffic accidents, seriously affecting the safety of drivers. Therefore, it is of great significance to judge whether the driver is in a fatigue driving state, and to give an alarm prompt to the driver in the fatigue driving state. [0003] At present, the fatigue driving warning device is often installed on the car dashboard in front of the driver...

AI Technical Summary

Problems solved by technology

Since the fatigue driving warning device is installed in front of the driver to monitor the driver's eyes, if the internal structure design of the warning device is unreasonable, resulting in an excessively large size of the warning device, the warning device will block the driver's line of sight, thereby affecting driving safety In addition, the surface of the car dashboard of the commonly used car is uneven, and the difference between the car dashboards of different car types is greater. The commonly used warning device installation method is limited and cannot meet the needs of different models.
