Emergency stop warning device for sedan cars

Abstract

The invention discloses an emergency stop warning device for sedan cars. The emergency stop warning device comprises a control component and a warning component, wherein the warning component furthercomprises a display component and a horn which are fixed in a trunk. During use, a person in a cab only needs to press a trunk switch and a double flash switch to send a warning signal to a back vehicle. The emergency stop warning device for the sedan cars has the advantages of quick layout and high identification degree and can effectively lower a rear-end collision risk.

Description

technical field

[0001] The invention belongs to the field of vehicle-mounted safety equipment, in particular to a device capable of reminding vehicles coming from behind and preventing rear-end collisions after accidental parking. Background technique

[0002] When a vehicle stops due to a breakdown on the road, a warning sign should be placed to remind the vehicle coming from behind. Article 68 of the "Road Traffic Safety Law" clearly requires: "When a motor vehicle breaks down on the expressway, ... the warning sign shall be set up 150 meters away from the direction of the broken down vehicle." On ordinary roads, it is also required to be placed tens of meters away. Cars carry triangular warning signs with them, but they are rarely placed within easy reach because they are not usually used. Once it is needed, it has to be taken out quickly and sent tens of meters or even one hundred and fifty meters away. Considering highway speeds, there is very little time left for th...

Examples

Embodiment 1

[0022] The lamps and lanterns of most of automobiles double as control line with power line, double flashing lights flicker is realized by intermittent power supply. The present embodiment is aimed at this kind of vehicle. The warning component includes a display component 2 and a horn 4 . The display part 2 is made of LED (Light Emitting Diode), and is fixed on the inner surface of the flat top portion of the trunk lid 3 by means of glue, screws or rivets. In the figure, for the sake of clarity, the display part 2 is drawn far away from the case cover 3, but they are actually close together. Loudspeaker 4 is installed in case cover corner. When the case cover 3 was opened, the display part 2 and the loudspeaker 4 were all naturally backward. The parts of the complete system except the display part 2 and the loudspeaker 4 are all accommodated in the electrical box 1, and the electrical box 1 is also contained in the trunk. Relay 51 is as control part, and its coil 61 is co...

Embodiment 2

[0025] This embodiment is basically the same as Embodiment 1, the difference is that: the monostable trigger 52 is used as the control component, its enable end 621 is connected with the trunk lock switch state line, the trigger input end 622 is connected with the double flashing power line, and The output terminal 72 is connected with the display part 2 and the speaker 4 . The transient state duration of the monostable flip-flop 52 is slightly longer than the period of the double flash. The monoflop 52 is enabled when the trunk is opened. If the double flash is also turned on at this time, the output terminal 72 will make the display part 2 and the speaker 4 work. Compared with the first embodiment, the display unit 2 and the horn 4 are continuously working in this example, which is conducive to sending clearer and more legible warnings.

Embodiment 3

[0027] The lights of some automobiles have dedicated control lines, and this embodiment is aimed at such vehicles. Basically the same as Embodiment 1, the difference is that there is no loudspeaker, and the single-chip microcomputer 53 is used as the control unit, and its two input terminals are connected with the trunk light control line and the double flash control line respectively, while the output terminal 73 is connected with the display unit 2. When the trunk is opened and the double flash is also opened, the single-chip microcomputer 53 can make the display part 2 work. In addition, the display part 2 includes two triangles on the left and right and a horizontal line in the middle.
