CN2825379Y - Vehicular antitheft igniting system - Google Patents

Abstract

The utility model discloses an anti-theft igniting system for a vehicle, which comprises an ignition switch, an igniter, a trigger and an ignition switch key with a plastic casing, wherein a Hall element is arranged in the ignition switch, and both ends of the Hall element are respectively connected with the igniter and the trigger; an iron block used for switching on the Hall element is arranged in the plastic casing of the ignition switch key. The utility model uses the iron block in the key to switch on the Hall element between the igniter and a trigger coil, and even though a newly matched key can switch on the ignition switch, a motor can not be started. Because no iron block is installed in the key, the Hall element in the ignition switch can not be switched on, and the ignition system can not form a closed circuit. Even though a circuit can be overlapped manually in traditional methods, because of the ignorance of the existence of the Hall element, even if the lap joint is completely correct, the vehicle can also not be started because the Hall element is not switched on. Therefore, the anti-theft measure of the utility model has very strong invisibility.

Description

The antitheft ignition system of a kind of power actuated vehicle

Technical field

The utility model relates to the ignition system that is used for power actuated vehicle, is specifically related to a kind of ignition system with anti-theft feature, belongs to electronic technology field.

Background technology

On power actuated vehicle, the effect of ignition system is that fuel oil in the cylinder and air Mixture are lighted, and promotes the piston acting, thereby makes vehicle to run, belongs to one of fundamental, and its effect and meaning are self-evident.Ignition system is made up of firing unit, ignition lock, high-tension coil, magneto generator, light-up plug and ignition key.In traditional ignition system, the binary pair of magneto generator directly is connected with firing unit by a lead, when key inserts ignition lock and rotates, disconnects whole ignition system formation C/LOOP when stopping working line, and firing unit work can normally start vehicle.Now the stolen phenomenon of vehicle is many, wherein a kind of theft means are because there is not key, can't make ignition system form the loop by key, so the thief on top of behind the line connecting relation of ignition system, directly replaces key that the ignition lock circuit is connected with hand.At the above-mentioned emerging driver's section of stealing, the someone has invented a kind of anti-theft igniting switch key, in this key coder is housed, and when having only coding consistent with the coding of demoder in the ignition system, ignition system could be worked; Otherwise even ignition lock is opened, car can not start yet, and anti-theft effect is relatively good.But above-mentioned anti-theft measure is very obvious, and ordinary people's a glance just can find that this car has anti-theft feature, and knows antitheft means thereby the method that can cause its searching to crack.Simultaneously, above-mentioned anti-theft measure complexity, the technical requirements height is difficult for repairing after damaging, and cost increases more, and is obvious to the price influence of car load.

The content of utility model

At the prior art above shortcomings, the purpose of this utility model is to provide that a kind of cost is low, the antitheft ignition system of the power actuated vehicle of good concealment.

The technical solution of the utility model is achieved in that the antitheft ignition system of a kind of power actuated vehicle, comprise ignition lock, have ignition key, firing unit and the binary pair of plastic casing, be provided with Hall element in the described ignition lock, the two ends of Hall element are connected with binary pair with firing unit respectively; Be provided with iron block in the plastic casing of described ignition key with the Hall element coupling.

Specifically, described Hall element is magnetic diode and is positioned at ignition lock sign postoperculum.

The utility model is owing to be provided with the Hall element of point of connection firearm and binary pair in ignition lock, the hidden iron block that mates with Hall element that is provided with the plastic casing of key (key body is a copper material) in simultaneously, before key inserts ignition lock, the not conducting of Hall element this moment, be open circuited between firing unit and the binary pair, after inserting key, iron block makes its conducting near Hall element in the key, thereby firing unit and also conducting of binary pair, just the same with prior art, thereby ignition system formation C/LOOP, vehicle can normally start.Antitheft effect of the present utility model and disguise thereof are embodied in: even the key bit of allotting again is from being living in appearance, key also can be opened ignition lock simultaneously, but is exactly can not start the engine.Because iron block is not installed in the key, can not make Hall element conducting in the ignition lock, ignition system can not form C/LOOP, and firing unit is not worked, and can not start vehicle certainly.Just be the thief by the manual overlap joint of orthodox method circuit, because of not knowing to exist Hall element, even overlap entirely true because not conducting of Hall element, i.e. not conducting of firing unit and trigger winding, so can not start vehicle.

The utility model is compared existing anti-theft measure, and is simple in structure, and the cost increase seldom.

Description of drawings

Fig. 1 is a schematic diagram of the present utility model.

Fig. 2 is the structural representation of Hall element in ignition lock.

Fig. 3 is the structural representation of iron block in ignition key.

The specific embodiment

The utility model is described in further detail below in conjunction with accompanying drawing:

Ignition system of the present utility model is made up of firing unit 1, ignition lock 2, high-tension coil 3, magneto generator 4 and light-up plug 5, and its circuit theory is referring to Fig. 1.From the figure as can be seen, the charge coil of magneto generator 4 is connected to firing unit 1 with firing unit 1 provides operating voltage, the trigger winding 10 of magneto generator 4 gives firing unit 1 with energizing signal by the Hall element in the ignition lock 27, by the primary winding of firing unit 1 with ignition signal entrance point fire coil 3, high-voltage signal after high-tension coil 3 boosts offers light-up plug 5 at last by secondary winding, light-up plug 5 produces electro spark under the effect of high-tension current, the carburetion mixture in the some gas cylinder.

Ignition lock is the switch part that the control ignition system quits work and resumes work, and reaches the purpose that is switched on or switched off circuit with it, and this being switched on or switched off by key finished.In the prior art, trigger winding directly is connected with firing unit by lead, and this part need not independent connection in ignition system, i.e. the function that trigger winding and firing unit is not switched on or switched off of key.This improved departure point just is being based on this, referring to Fig. 2, being positioned at sign in ignition lock 2 covers 6 rear portions and is provided with Hall element 7, the Hall element of present embodiment is magnetic diode or triode, the two ends of Hall element 7 are connected with trigger winding 10 (being binary pair) with firing unit 1 respectively, and annexation as can be seen from Figure 1.Referring to Fig. 3, be provided with iron block 8 in the ignition key, the effect of iron block 8 be when its can be when the Hall element 7 with Hall element 7 conductings.Because Hall element is switched on, correspondingly, firing unit and trigger winding also are switched on.Because iron block 8 is arranged in the plastic casing 9 of key, can't see that from the outside the person of being out of the swim does not know that the inside also keeps iron block, so disguise is very strong.

Claims (2)

1, the antitheft ignition system of a kind of power actuated vehicle, comprise ignition lock (2), firing unit (1), binary pair (10) and have the ignition key of plastic casing (9), it is characterized in that: be provided with Hall element (7) in the described ignition lock (2), the two ends of Hall element (7) are connected with binary pair (10) with firing unit (1) respectively; Be provided with the iron block (8) that is used for conducting Hall element (7) in the plastic casing of described ignition key (9).
