Description

Emergency stop warning device for car

Technical Field

The invention belongs to the field of vehicle-mounted safety equipment, and particularly relates to equipment capable of reminding a driver of a coming vehicle behind and preventing rear-end collision after unexpected parking.

Background

When the vehicle parks on the road due to a fault, a warning sign is placed to remind the driver of coming the vehicle behind. The sixty-eight explicit requirements of the road traffic safety law are as follows: "the … … warning flag should be set beyond one hundred fifty meters of the coming direction of a failed vehicle when the vehicle fails on the highway". On ordinary roads, tens of meters are also required. The triangular warning sign is carried by the car, but the triangular warning sign can not be used at ordinary times, so the triangular warning sign is rarely placed in a place where the car can be reached by a user. Once it is ready for use, it is quickly removed and sent to tens of meters, even one hundred and fifty meters. Little time is left for the driver in view of highway speeds. An automobile with 120km per hour can drive over 150 meters in 4.5 seconds. Meanwhile, the warning sign is only about 40 cm square and is not obvious enough when placed on the ground. Therefore, the existing method for manually laying warning signs has great risk and poor effect.

The invention relates to a triangular warning board connecting structure (CN 203472710U), which provides that a warning sign is stored on an upper cover of a trunk so as to be convenient to take and use, but the warning sign can work only after being sent to a remote place by walking, so that the time cannot be shortened remarkably. The invention discloses a highlight automobile warning board (CN 204020706U), which proposes that a triangle warning sign is hung on an inner trunk cover of a trunk to be seen by a rear vehicle, but the invention requires that a contact piece is arranged on the trunk, and if the contact piece is in poor contact due to vibration and goods extrusion, the contact piece is forced to malfunction or not work. Furthermore, according to the invention, the warning sign is automatically activated each time the trunk is opened, which is obviously not the case with everyday vehicles. Finally, the invention "hangs" the warning sign in the trunk, affecting the cargo.

Disclosure of Invention

In view of the disadvantages of the prior art, the invention aims to provide a warning sign which is special for a car, can be set quickly and is sufficiently striking.

The invention is realized by the following steps:

the whole device comprises a warning component and a control component. The warning means includes at least one of a display means and a speaker. The display part is a light source fixed on the inner surface of the flat top part of the trunk lid of the car and is used for displaying a warning pattern in a flashing or constantly-bright mode. The display element is fixed here with the advantage that, on the one hand, it is naturally flushed back when the lid is opened and is located in the shadow of the lid itself, which is more conspicuous, and, on the other hand, it engages the inner surface of the lid, only slightly protruding and has little effect on the cargo. The specific structural features and implementation of the display component are as follows: a plurality of light sources are soldered to the substrate and form a warning pattern. The light source is a Light Emitting Diode (LED) or a Laser Diode (Laser Diode), the latter being brighter and smaller and having been used as a headlight on a few vehicle models such as bmark i 8. The substrate is FPC (flexible circuit board) or PCB (printed circuit board), and is fixed on the case cover by double-sided adhesive tape, screws or rivets. There are two patterning methods depending on the shape of the substrate. In the case of an elongated substrate, the substrate may be cut into segments (each segment having a row of light sources) that are used as lines to form a warning pattern. The method has the advantages of saving materials and directly using the LED lamp bar (also called as a 'lamp strip') which is commercially available. The LED lamp strip has been widely used for automobile decoration, and has sufficient market supply and low cost. If the substrate is a bulk substrate, a light source can be used to form a dot pattern. The method has the advantage of convenient installation. However, in both the elongated and the massive substrates, the light source is welded on the substrate, the substrate is fixed on the box cover, the power lines between the substrates are interconnected (the power lines can be fixed on the surface of the box cover by double-sided adhesive tape, wire fasteners, wire clamps or sleeves, and are led from one substrate to the other substrate), and the light is emitted after the power is on. In the aspect of size, the thickness of the LED lamp strip commonly found in the market is about 7mm, and the total thickness of the large substrate and the light source does not exceed 1 cm. In other words, the inner part of the box cover only protrudes less than 1cm, and the influence on the goods loading is very small. It is also emphasized that: the display member is fixed to a flat top portion of the cover, i.e., a portion parallel to the floor when the cover is closed, and is erected and directed rearward when the cover is opened. The display device is fixed at the position, so that the display device is convenient to see from the back. In addition, the inner surface of the trunk cover is slightly cambered, and the display component is correspondingly cambered, so that light rays are emitted to the rear in a fan shape and can be seen by vehicles coming in a large range. The warning pattern is in accordance with the requirements of traffic regulations. In terms of the regulations at the time of filing of the present invention, a triangle indicating "warning", right and left arrows indicating "turn", and a horizontal straight line indicating "drive-in prohibited" may be used as the warning pattern. Therefore, at least one of the three patterns can be used as a warning pattern.

The horn is fixed on the tail of the vehicle, the inside of the trunk or the trunk cover by double-sided adhesive tape, screws or rivets. In contrast, if fixed to the lid, the horn rises when the lid is opened, facilitating sound transmission. But if the horn is larger and heavier, the horn can be placed in a trunk. If the warning device comprises the display device and the loudspeaker at the same time, the warning device can send visual and audible warnings at the same time, and the warning device and the loudspeaker are connected in parallel to improve the robustness of the system. However, the warning device may include only one of the two, which is of course less effective.

The control component is used for starting the warning component at proper time. The control logic is: the warning feature is activated if and only if the trunk is open and the dual flashing lights are active. Before describing the implementation in detail, the related background knowledge will be introduced. The trunk lock of the automobile is provided with a state line (a 'trunk lock switch state line') for reflecting whether the lock is opened or not, and if the lock is opened, the trunk cover is opened. The trunk is also provided with a lamp which is controlled by a trunk lighting control line, and the lamp can be lightened when the trunk cover is opened. Therefore, whether the trunk lid is opened or not can be judged through the trunk lock switch state line or the trunk illumination control line. In addition, a 'double-flash control line' (which is also used as a steering lamp line in some vehicle types) leading to a tail lamp is arranged, and whether a driver turns on the double-flash can be judged by using the line. The implementation of the control means is such that: the logic AND part is realized by a relay or a relay group, a logic circuit and a singlechip module. One input of the intelligent control system is a trunk lock switch state line or a trunk illumination control line (the specific selection depends on the difficulty of wiring, and the trunk lock switch state line can only be selected if a few vehicle types do not have trunk lamps), the other input of the intelligent control system is a double-flash control line, and the output of the double-flash control line is communicated with a warning component. Need to explain: the original line of the automobile is not cut off and then connected into the control part, but one line is separated to be connected into the control part, so that the original function is reserved. The control component is arranged in the electric box and is fixed in the trunk by double-sided adhesive tape, screws or rivets, and the incoming and outgoing electric wires are fixed by the double-sided adhesive tape, wire buckles, wire clamps or sleeves.

The power cord of the kit is connected to the vehicle power supply line, but preferably also includes a battery and a manual switch, the battery being connected to the warning device via the manual switch. The warning feature may be manually activated when the vehicle is powered down or the control feature is malfunctioning.

The using method of the invention is as follows: when the trunk lid is opened and the double flashing light switch is pressed in the cab, the warning member starts to display a warning pattern and generate a warning sound. In case of power failure of the whole vehicle or failure of the control component, the manual switch is pressed down, and the battery is used for working.

The outstanding substantive features and remarkable progress of the technical scheme of the invention are mainly reflected in that: the device can be quickly set, is very striking, has high reliability and does not influence daily use.

Detailed Description

In order to make the objects, technical solutions and advantages of the present invention more apparent, the following description is further provided with reference to the accompanying drawings and embodiments.

The first embodiment is as follows:

the power line of most automobile lamps is also used as a control line, and the flashing of the double-flashing lamp is realized by intermittent power supply. The present embodiment is directed to such a vehicle. The warning means comprises a display means 2 and a speaker 4. The display part 2 is formed by a commercial LED lamp strip, the width of the display part is 10mm, the thickness of the display part is 7mm, the display part is flexible and can be twisted, and double-sided adhesive tape is arranged on the back of the display part. According to different manufacturers, 60 or 120 LED lamp beads are arranged on each meter of the lamp strip. The lamp strip is cut into small sections as lines and is pasted on the inner surface of the flat top part of the trunk lid 3 to form arrow-shaped warning patterns. The display part 2 is drawn relatively far from the cover 3 for clarity and is actually close together. The horn 4 is arranged at one corner of the box cover. When the cover 3 is opened, the display part 2 and the speaker 4 are naturally directed backward. The whole set of system components except the display component 2 and the loudspeaker 4 are accommodated in the electrical box 1, and the electrical box 1 is also fixed in the trunk by screws or rivets. The relay 51 is used as a control part, and a coil 61 of the relay is connected with a trunk illumination power line, a normally open contact 71 is connected with a double lightning power line, and a movable contact is connected with the display part 2 and the loudspeaker 4. The battery 8 is also connected to the display unit 2 and the speaker 4 via a manual switch 9. For ease of operation, a hole is made in the electrical box 1 to expose the manual switch 9.

The principle and the using method are as follows: at ordinary times, the box cover 3 is closed, the trunk illuminating lamp is not electrified, and the relay 51 is disconnected. When the driver opens the box cover 3 and double flashes, on one hand, the trunk illuminating lamp is electrified to attract the relay 51, and on the other hand, the power supply of the double flashes is always opened, the contact 71 and the movable contact are sent to the display part 2 and the loudspeaker 4 to enable the display part 2 to flash and sound. If the vehicle is powered off or the relay 51 fails, the manual switch 9 is pressed, and the display unit 2 and the speaker 4 are driven by the battery 8.

Example two:

this embodiment is basically the same as the first embodiment, except that: the monostable trigger 52 is used as a control component, the enable terminal 621 of the monostable trigger is connected with a trunk lock switch state line, the trigger input terminal 622 is connected with the double lightning power lines, and the output terminal 72 is connected with the display component 2 and the loudspeaker 4. The transient hold time of the monostable flip-flop 52 is slightly longer than the double flash period. When the trunk is open, the monostable trigger 52 is enabled. If the double flash is also turned on, the output terminal 72 will make the display unit 2 and the speaker 4 operate. Compared with the first embodiment, the display part 2 and the loudspeaker 4 are continuously operated in the present embodiment, so that a clearer and more easily-distinguished warning is sent.

Example three:

some automotive lights have dedicated control wires and the present embodiment is directed to such vehicles. Basically the same as the first embodiment, except that there is no speaker, and the single chip module 53 is used as the control unit, and its two inputs are connected to the trunk lamp control line and the dual flash control line, respectively, and the output 73 is connected to the display unit 2. When the trunk is opened and the double flash is also opened, the one-chip microcomputer 53 causes the display section 2 to operate. Further, the display section 2 includes two left and right triangles and a horizontal line in the middle. The middle horizontal line is composed of LED lamp strips, the two triangles are formed by welding a plurality of laser diodes on a substrate (PCB circuit board) to form a triangular lattice pattern, and the substrate is fixed on the trunk cover by screws or rivets.
