Description

Parking car enabling sound and blue taillight attention device

Technical field

This utility model belongs to electronic technology and technical field of automotive electronics, relates to a kind of parking car enabling sound and blue taillight attention device.

Background technology

It is part minor matter that door opening seems, but damage majority all ratios that accident causes are more serious, because door opening is taken by surprise. Particularly electric bicycle is skyrocketed through in recent years, and the speed generally too fast probability also allowing this type of accident occur increases further. According to incompletely statistics: in these accidents, 60% is directed to electric bicycle, and the ratio that taxi has an accident is the highest, about about 30%. Additionally, the accident ratio that sedan car door opening causes is about about 60%, the accident that other types opening door of vehicle causes is about about 10%.

The traffic police of process accident explain, this is because part renting car driver races against time, and inadequate specification when often stopping, sometimes forget again passenger is reminded, neglected during enabling and first observed door opening again, result in the passenger pedestrian accident that opens the door and happen occasionally. In the accident that taxi and car cause, mostly opened what car door caused by passenger, and the accident caused by driver's door opening also accounts for certain ratio.

How at utmost to prevent " door opening " accident from occurring? the heaviest is to choose parking spot, and door opening first opens bar seam! Before door opening, before and after reply, pedestrians, Vehicular behavior are conscientiously observed, confirm after safety can door opening, especially taxi person for driving a car also should remind before rider is opened the door in time; Except driver, rider gets off from right side as far as possible. As traffic participant, it is no matter the passenger in automobile driver, car or the people of electric motor car is ridden on road surface and pedestrian will take care.

Parking car enabling sound described in the utility model and blue taillight attention device are to utilize electronic technology means, use a small amount of discrete electric sub-element element manufacturing, this utility model warning personnel by bus note the electric motor car ruuning situation observed after following car closely when door opening, remind cycling personnel below to note dodging by blue taillight simultaneously.

Parking car enabling sound described in the utility model described further below and blue taillight attention device involved necessity, guardian technique content in implementation process.

Utility model content

Goal of the invention and beneficial effect: it is part minor matter that door opening seems, but damage majority all ratios that accident causes are more serious, because door opening is taken by surprise. Particularly electric bicycle is skyrocketed through in recent years, and the speed generally too fast probability also allowing this type of accident occur increases further. Parking car enabling sound described in the utility model and blue taillight attention device are to utilize electronic technology means, use a small amount of discrete electric sub-element element manufacturing, this utility model warning personnel by bus note the electric motor car ruuning situation observed after following car closely when door opening, remind cycling personnel below to note dodging by blue taillight simultaneously.

Circuit operation principle: when on and off switch SW connects 12V DC source, the 12V battery tension of automobile is added on circuit, the circuit of now parking car enabling sound and blue taillight attention device is in holding state. When car door is shut, 4 the gate controlled switch AN1��AN4 being serially connected are in on-state, and 12V direct current power source voltage is added in the two ends of resistance R1, makes silicon rectifier diode D2 end. The effect of visible resistance R1 is to stop NPN transistor VT1 conducting, and at this moment the circuit of sound and blue taillight attention device is in holding state. If by bus personnel open car a certain car door, corresponding gate controlled switch goes off state, circuit through electrochemical capacitor C1 time delay less than 1 second, the rapid conducting of NPN transistor VT1, then unidirectional controllable silicon S CR conducting is triggered, high loudness piezoelectric buzzer HA is driven to pipe, blue taillight is lighted at once, show that a certain car door has already turned on this moment, warning personnel by bus note the electric motor car ruuning situation observed after following car closely when door opening, remind cycling personnel below to note dodging by blue taillight simultaneously.

Even if the personnel that at this moment ride close rapidly entrance door, unidirectional controllable silicon S CR still maintains conducting, piezoelectric buzzer HA pipes without stopping, and blue taillight LED maintains illuminating state. Making parking car enabling sound and blue taillight attention device circuit reset, cut off 12V DC source only by and off switch SW, high loudness piezoelectric buzzer HA just can stop piping, blue taillight just can extinguish.
