Problems solved by technology

At the same time, the warning sign is only about 40 cm square, and it is not obvious enough to be placed on the ground
Therefore, the existing method of manually laying warning signs is extremely risky and ineffective
[0003] Invented "A Triangular Warning Sign Connection Structure" (CN203472710U) proposed to store the warning sign on the upper cover of the trunk for easy access, but it still needs to be transported to a distance by walking before it can work, so the time cannot be significantly shortened
The invention "High Brightness Automobile Warning Sign" (CN204020706U) proposes to hang the triangular warning sign on the inner cover of the trunk for the rear vehicles to see, but the invention requires a contact piece to be installed on the trunk. If the contact is poor, it is bound to malfunction or not work.

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 a commercially available LED light strip, with a width of 10mm and a thickness of 7mm, which is flexible and twistable, and has double-sided adhesive tape on the back. Depending on the manufacturer, there are 60 or 120 LED beads per meter of light bar. The light bar is cut into small sections, and as lines, it is pasted on the inner surface of the flat top portion of the trunk lid 3 to form an arrow-shaped warning pattern. 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...

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 module 53 is used as the control unit, and its two input terminals are respectively connected with the trunk light control line and the double flashing control line, 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. The horizontal line in the middle is composed of LED light strips, and the two triangles are welded on the substrate (PCB circuit board) with multiple laser diodes to form a triangular lattice pattern, and then the substrate is fixed on the trunk lid with screws or rivets.

Abstract

The invention discloses an emergency stop warning device for cars. The emergency stop warning device comprises a control component and a warning component, and the warning component further comprisesa display component and a trumpet which are fixed inside a trunk. When the emergency stop warning device for the cars is used, a person inside a driving cab will send warning signals to the cars coming from the rear just needing to press down a trunk switch and a double-flash switch, the emergency stop warning device for the cars has the advantages of being rapid to arrange and high in identification degree, and the risk of rear-end collision is effectively reduced.

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...
