Embodiment

[0028] When the vehicle is running and encounters rain, the output voltage of the rain sensor increases with the increase of rainfall received by the detection end of the rain sensor located on the outer surface of the vehicle body. When the first input end of the voltage comparator and the second When the voltage difference at the input terminal is greater than the threshold value, the voltage comparator outputs a high level to turn on the triode VT to energize the main relay KA, so that the normally open contact is closed and the normally closed contact is disconnected, so that the frequency high-speed gear circuit The accelerating resistor is connected in series with the electromagnet coil to reduce the electromagnet current to reduce the suction force of the electromagnet and reduce the cooling time of the heating wire required for the heating wire to pull the moving contact away from the fixed contact, so as to speed up the switching frequency of the strobe switch , so tha...

Abstract

The invention provides a dual-gear-automatic-switching heating-wire flasher circuit. The dual-gear-automatic-switching heating-wire flasher circuit comprises a direct-current power source, a stroboscopic circuit and a frequency high-gear circuit; the stroboscopic circuit comprises an electromagnet and a stroboscopic switch pulled by a heating wire; a fixed contact of the stroboscopic switch is connected with an electromagnet coil, and a movable contact of the stroboscopic switch is connected with the heating wire; when the stroboscopic circuit works, the heating wire is heated and extends, themovable contact is connected with the fixed contact accordingly, the electromagnet coil is connected with an electric heating loop in parallel, the movable contact is attracted to the fixed contact through the magnetic force of the electromagnet, the heating wire is cooled and shrunk, and then the movable contact is pulled away to generate stroboscopic signals; the frequency high-gear circuit comprises an accelerating resistor and a rainfall detecting circuit, when the rainfall reaches a threshold value, the accelerating resistor is connected with the electromagnet coil in series through therainfall detecting circuit, and heating-wire cooling time required when the heating wire pulls the movable contact from the fixed contact is shortened to increase the switching frequency of the stroboscopic switch. By means of the dual-gear-automatic-switching heating-wire flasher circuit, vehicle lamps can have two flash rates, and the two flash rates can be automatically switched according to the rainfall in the vehicle driving process.

Description

technical field [0001] The invention relates to the technical field of electrical equipment, in particular to a dual-speed automatic switching electric heating wire flasher circuit. Background technique [0002] The flasher is a commonly used strobe device in vehicle lights, but the current heating wire flasher only has one flash frequency, and the flashing frequency of the heating wire flasher cannot be changed according to changes in rainy weather, which affects the vehicle lights. The function of how to solve it is a research direction. Contents of the invention [0003] The invention proposes a dual-speed automatic switching electric heating wire flasher circuit, which can allow vehicle lights to have two flashing frequencies and can automatically switch according to the amount of rainfall suffered by the vehicle during driving. [0004] The present invention adopts the following technical solutions. [0005] A heating wire flasher circuit with dual gears and automat...
