Motorcycle power supply switch flameout circuit

Abstract

The invention discloses a motorcar power switch flameout circuit, which is characterized in that a field effect tube whose source electrode is connected with a battery anode, drain electrode is connected with a whole-car power can be a power switch tube, a single-way thyristor anode is connected with a flameout line whose cathode is connected with ground and gate electrode is connected on the flameout line through a resistance and a diode by capacitance, the needed trigger current can be acquired. When the power control end makes the power switch tube conduct the whole-car power and the current triggers the ground short-circuit thyristor which stops and breaks the flameout line, the vehicle can be normally started. When the whole-car flameout is closed and the control of the thyristor trigger electrode is broken, the ignition power on the flameout line trigger and conduct the thyristor and the flameout line grounds short-circuit and the vehicle flames out and can't be started. The circuit has no trigger point, no static power consumption and is low in cost, which has wide prospect in the application fields such as motorcar burglarproof device, ignition switch, motorcar automatic control and the like.

Description

technical field [0001] The invention relates to a motorcycle power switch flameout circuit, in particular to a motorcycle power switch flameout circuit which is controlled by an active device in a passive state and has no static power consumption. Background technique [0002] In the current prior art, the motorcycle ignition switch is the simplest and also adopts a double-pole double-throw switch to realize closing the whole vehicle power supply and extinguishing the engine by shorting the flameout control terminal to the ground; Affecting the normal switch and flameout function of the car key, three relays are used to switch the switch and flameout function of the whole vehicle power supply, one normally open relay is used for the whole vehicle power switch, one normally closed relay and the other normally open The type relay is used to turn on the flameout wire and ground the flameout wire, so as to achieve the functions of keyless driving, remote start, remote flameout a...

[0002] In the current prior art, the motorcycle ignition switch is the simplest and also adopts a double-pole double-throw switch to realize closing the whole vehicle power supply and extinguishing the engine by shorting the flameout control terminal to the ground; Affecting the normal switch and flameout function of the car key, three relays are used to switch the switch and flameout function of the whole vehicle power supply, one normally open relay is used for the whole vehicle power switch, one normally closed relay and the other normally open The type relay is used to turn on the flameout wire and ground the flameout wire, so as to achieve the functions of keyless driving, remote start, remote flameout and anti-robbery; especially, the active device cannot be solved to close the flameout circuit when the battery is damaged and the circuit has no power supply. problem, so the flameout circuit can only be closed by using the relay contact in the case of no power supply and the relay reset function

Due to too many switch contacts, complex structure, too many relays, large volume, high cost, and limited service life of contacts, it not only increases the fault range of the product, but also is not conducive to the miniaturization and automation design of the product.
