Vehicle warning device and accident instant warning method

Abstract

The first aspect of the present invention provides a vehicle warning device, which includes a vehicle collision detection unit, the vehicle collision detection unit is connected to a control unit, the control unit is connected to a pop-up device, and the control unit is also connected to an audible and visual alarm device. The control unit is connected with a power supply, the control unit is connected with a control button, and the control unit is connected with a reset button. The second aspect of the present invention provides an instant warning method for accidents, which includes a. The inertial sensor of the vehicle detects the vehicle collision signal, and compares the value of the collision signal with the set value; b. The control unit controls the pop-up of the warning sign; steps a and b are executed in sequence, and the warning sign pops up. The installation position of the vehicle warning device and the instant warning method for accidents provided by the present invention is on the top of the vehicle, which is easier to be found by distant vehicles; and the warning device in the warning method does not need to be manually assembled and placed, and can be popped up by itself when needed, and can be removed when not in use. Take it back on your own.

Description

technical field [0001] The invention relates to a vehicle warning device and a warning method, in particular to a pop-up vehicle warning device. Background technique [0002] In recent years, there have been frequent accidents of secondary collisions caused by faulty vehicles not placing warning signs in time. These accidents can increase the injuries of people in the vehicles, and cause casualties and economic losses in severe cases. At present, most of the car warning signs we use are foldable. They are usually folded and placed in the car. When encountering a traffic accident or car failure, they are manually taken out and opened into a triangle and placed on the ground at a certain distance behind the car. Play a safety warning role for passing vehicles to avoid collisions. But there is following shortcoming in this safety warning method: 1, because warning sign area is less and is placed on the ground, cause target not conspicuous, can not find and slow down in time fo...

But there is following shortcoming in this safety warning method: 1, because warning sign area is less and is placed on the ground, cause target not conspicuous, can not find and slow down in time for the vehicle of high-speed running, just finds when often very close to accident vehicle; 2. For the users, there are certain safety hazards in the placement of safety signs, especially on expressways, where they may be injured during the placement process; 3. In some serious traffic accidents, people in the car may be injured and lost Mobility, unable to walk on their own to place warning signs

[0003] The Chinese utility model patent with the application number of 93210034.1 discloses a car anti-rear collision and reversing anti-obstacle warning device, which includes a display warning circuit and a host, and uses the principle of ultrasonic transmission-reception to send flashing signals or red light and white light on the display screen. This effectively reminds the driver of the car behind to prevent rear-end collisions. This warning device is easy to install, but it cannot automatically pop up when the vehicle breaks down, and the font displayed on the display screen is not easy to see clearly in the distance, which may easily cause the driver of the car behind to misunderstand. as attached figure 1 , attached figure 2 shown
