Abstract

A vehicle electrical anti collision device is provided on the front part of the vehicle with a transmitting probe, wherein, the relay of the controller is connected with a vehicle ignition coil and a braking controller. When the vehicle drives within the safety distance from the front vehicle, the circuit works to automatically extinguish and brake so as to avoid collision accident. The utility model is especially suitable for highway driving during the snow rainfall or heavy mist in order to ensure the safety drive of vehicles.

Description

The motor vehicle electronic anticollision device

The utility model belongs to electronics package, is specifically related to a kind of structure of motor vehicle electronic anticollision device.

Along with developing rapidly of highway in China communication, express highway, high-grade highway constantly increase, for running at high speed of vehicle provides convenience, but thing followed traffic accident is also in rising trend, particularly sleety weather or have a dense fog because Vehicle Speed is fast, is easy to cause traffic accident, cause damage for the country and people's lives and properties, also do not have a kind of electronic control package of anti-vehicle collision at present.

The purpose of this utility model is: design a kind of motor vehicle electronic anticollision device, be installed on vehicle after, can avoid collision happens effectively, reduce the generation of traffic accident.

The purpose of this utility model is achieved in that installs an electron detection device in the front portion of vehicle, control relay contact fire coil and brake actuator, when find the place ahead at safety distance with interior when vehicle is arranged, this detector sends signal, cutting off the vehicle circuit makes vehicle flame-out, make car brakeing simultaneously, make vehicle and front truck keep crash-proof safety distance.

The concrete device circuit of this technical scheme is: exploring antenna connects ic chip ₁Y ₁, Y ₂, ic chip ₁On the V pin meet IC ₂Its centre of 1 pin also meets RT, D ₁An end and the C of negative pole, K ₁Positive pole, IC ₁0 pin meet D ₁The other end of anodal and K is behind the L pin power connection positive pole and connect another pin of RT and capacitor C ₁Negative pole, IC ₂2 pin, IC ₁W ₁, W ₂Serial connection adjustable resistance RP between the bipod, IC ₂3 pin power connection negative poles, output termination vehicle ignition electric coil and the brake actuator of K.

Fig. 1 is the utility model scheme of installation

Fig. 2 is the utility model structural representation

Fig. 3 is the utility model circuit diagram

Among the figure: 1, relay, 4, the brake actuator in detector transmitting probe, 2, electron detection device, 3, the vehicle ignition coil.

Introduce the utility model implementation method below in conjunction with accompanying drawing: the transmitting probe 1 of electronics anticollision device is installed on front part of vehicle, this device control relay 2 connects vehicle ignition coil 3 and brake actuator 4, when in probe 1 is sensed the place ahead safety distance, vehicle being arranged, device 2 sends signal cut high-tension coil 3, make vehicle flame-out, drive brake actuator 4 simultaneously, make vehicle brake, guarantee that vehicle does not bump against with front truck.

Electronic control package 2 is made up of integrated circuit, and detection range is adjustable according to the speed of a motor vehicle and road surface situation, and very strong bite is arranged, and is fit to the monitoring when travelling of night and greasy weather, and its circuit connecting mode is: detecting head two termination IC ₁Y ₁, Y ₂Between bipod, IC ₁On the V pin meet IC ₂1 pin and centre also meet RT, D ₁An end and the C of negative pole, K ₁Positive pole, IC ₁The O pin meet D ₁The other end of positive pole and K, L pin power connection positive pole, another pin of its indirect RT and capacitor C ₁Negative pole, IC ₂Pin, IC ₁W ₁, W ₂Serial connection adjustable resistance RP between the bipod, IC ₂3 pin power connection negative poles, output termination vehicle ignition electric coil 3 and the brake actuator 4 of K.

The element referential data of this circuit is: IC ₁Be TWH9250, IC ₂Integrated package of pressure-stabilizing is 7812, and K is small-sized sealing DC relay 4088 or 4098, D ₁Be IN4007-diode, RP 510K adjustable resistance, RT photoconductive cell, photoresistance is less than IK Ω, and resistance in the dark is greater than 2M Ω.

The utility model detectivity height; can be under the situation that navigating mate is not reacted as yet; action in advance; be night and fog precipitation weather vehicle safety fender guard; can be installed on various vehicles; when needing detector work slowly or not in the many speed of a motor vehicle of obstacle, this device can be closed, recover usual driving condition.
