A kind of fatigue driving warning device

Abstract

A fatigue driving warning device includes a body. The front face of the body is provided with a rectangular groove. The back face of the rectangular groove communicates with the outside. The lower part of one side of the rectangular groove is provided with a strip-shaped through groove. All of the outer side, the front face and the back face of the strip-shaped through groove communicate with theoutside. The upper ends of a plurality of first springs are connected to the top face of the rectangular groove. The first springs are uniformly distributed in the rectangular groove. The lower ends of the first springs are fixedly connected to the top face of one pressing plate. Two sides of the pressing plate are respectively provided with T-shaped grooves. Two sides of the body are respectivelyprovided with inverted L-shaped grooves. The inner sides of the inverted L-shaped grooves are respectively provided with inverted L-shaped through grooves communicating with the inside of the rectangular groove. According to the invention, a wireless charging input end can be installed on a power supply, and a wireless charging output end is installed at a USB port beside a cigarette lighter in avehicle through a conductive plug, so that charging while using can be realized, and charging can be carried out through wireless electric energy transmission, which is more safe and convenient.

Description

technical field [0001] The invention belongs to the technical field of safety warning, in particular to a fatigue driving warning device. Background technique [0002] Driving fatigue refers to the phenomenon that the driver's physiological function and psychological function are out of balance after driving continuously for a long time, and the driving skill declines objectively. If you continue to drive the vehicle after fatigue, traffic accidents are likely to occur. For this reason, products to prevent fatigue driving have been developed both at home and abroad, such as alarms worn on the ears, but generally drivers do not want to hang them on the ears. It is estimated that it is too late to wait for the driver to lower his head before calling the police; the fatigue driving warning system is a driving assistance warning system based on machine vision technology, which can detect the driver's fatigue and distraction in real time and provide alarm information, but its co...

If you continue to drive the vehicle after fatigue, traffic accidents are likely to occur

For this reason, products to prevent fatigue driving have been developed both at home and abroad, such as alarms worn on the ears, but generally drivers do not want to hang them on the ears. It is estimated that it is too late to wait for the driver to lower his head before calling the police; the fatigue driving warning system is a driving assistance warning system based on machine vision technology, which can detect the driver's fatigue and distraction in real time and provide alarm information, but its cost It is relatively high, not affordable for ordinary drivers, and it needs to be installed in the car body, and it is difficult to disassemble and assemble, so it cannot be widely used
