CN2313782Y - Indicator for safetyly braking of automobile - Google Patents

Abstract

The utility model relates to an indicator for the safe brake of automobiles, which can respectively send out different optical signals of green, yellow and red when the automobile normally runs and decelerates for brake. The utility model is composed of a relay, a switch and a display. The utility model can make the driver of the rear automobile to rapidly and aforehand learn whether the front automobile has change to prevent the front and the rear automobiles from collision, etc.

Description

The automobile safety braking prompting device

When relating to automobile normal running, deceleration, brake, can send the utility model the automobile safety braking prompting device of the signal of not sharing the same light, it can promptly allow back vehicular drive personnel learn that in advance front driving vehicle situation does not have not variation, generation with accidents such as vehicle collisions before and after preventing

In recent years, along with the variation and the transportation and communication of China's traffic route is doubled and redoubled, building up of express highway and city overhead road particularly, the speed of a motor vehicle also increases at double, increases and traffic accident is also corresponding, for the automobile driver, if can learn the preceding vehicle situation of change of travelling in advance, just can bull point safety, traffic accident in few a minute takes place, and the automobile tail stoplight stop lamp has only the variation of moulding up till now and do not have functional variation

The purpose of this utility model designs a kind of later-model brake taillight---automobile safety braking prompting device, and behind car engine, promptly when stopping, prompting device shows steady yellow; When automobile during at cruising, prompting device shows green light signals; When car deceleration, prompting device shows steady yellow; When braking automobile, prompting device shows red signal, this shows: when high vehicle speeds, if generation sudden stop, prompting device demonstration are red light after converting amber light to by green light, the brake signal time ratio shifted to an earlier date 80% originally like this, for back trailer brake provides a brake safety signal in advance

In order to achieve the above object, the utility model is achieved like this: select two to have at least one relay normally closed and an open contact, the exciting coil of one of them relay joins by the BK Brake Switch and the positive supply of automobile, other end ground connection, the exciting coil of another relay then joins by Oil Switch and positive supply, the other end is ground connection also, the common junction of the normally closed contact of last relay and a back relay is joined, and open contact and prompting device red eye join, the normally closed contact and the prompting device yellow signal light of back one relay join, and open contact is connected to the prompting device greensignal light; The common junction and the positive supply of last relay join, this shows, when promptly stopping behind the car engine, the common junction positive supply of last relay is connected, power supply is by the normally closed contact of last relay, the normally closed contact and the connection lead of back one relay, the telltale yellow signal light gets electric and shows; When automobile normal running, Oil Switch is connected, and back one relay exciting coil gets electric, and normally closed contact tripping, and open contact closure make the telltale greensignal light get electric and show; When automobile runs into situation, when closing throttle, Reduced Speed Now, back one relay exciting coil outage normally closed contact and Chang Kai touch the recovery virgin state, the telltale yellow signal gets electric and is yellow, when braking automobile, and the BK Brake Switch closure, the tripping of last relay normally closed contact, and the open contact closure, the telltale red eye gets electric and takes on a red color

Accompanying drawing is the utility model electrical schematic diagram,

With reference to the accompanying drawings, the utility model is by relay 1, relay 2, display 3, switch 4 and 5 form, and relay 1 and 2 is two to have a normally-closed contact and one and often open tactile The common relay of point, display 3 is by 9 groups in cabinet 6 and red light 7, amber light 8 and green light Become, switch 4 is vehicle brake switch, and switch 5 is the gas switch, relay 1 Excitation coil joins other end ground connection by brake switch 4 and positive supply; Relay 2 Excitation coil joins other end ground connection, relay 1 by Oil Switch 5 and positive supply The common junction of normally-closed contact and relay 2 is joined, the normally opened contact of relay 1 and demonstration The red eye 7 of device 3 joins; The yellow of the normally-closed contact of relay 2 and display 3 Signal lamp 8 joins, and the normally opened contact of relay 2 connects the greensignal light 9 of display 3, Common joint and the positive supply of relay 1 join.

Embodiment: among the embodiment of the present utility model, the prompting device display lamp adopts three groups of light-emitting diodes, is divided into three rows and is installed in the lamp box, and the display lamp power supply adopts 6～12V.

After adopting the utility model, brake red signal front-back vehicle driver can see the steady yellow after throttle is closed earlier, therefore can remind the back vehicle to notice that preceding vehicle will brake, advance time 80 percent, can remind back car driver to note like this, vehicle bumps against before and after reducing, and therefore, uses on the vehicle that this device is specially adapted to run at high speed.

Claims (3)

1. automobile safety braking prompting device of forming by relay, signal indicator and switch, the exciting coil that it is characterized in that relay 1 joins by vehicle brake switch 4 and positive supply, and other end ground connection, the exciting coil of relay 2 joins by Oil Switch 5 and positive supply, other end ground connection, the common junction of the normally closed contact of relay 1 and relay 2 is joined, and the red eye 7 of open contact and demonstration 3 joins; The yellow signal light 8 of the normally closed contact of relay 2 and telltale 3 joins, and open contact connects the greensignal light 9 of telltale 3.

2. automobile safety braking prompting device according to claim 1 is characterized in that relay 1 and 2 is two common relays with a normally closed contact and an open contact.
